Abs cracked peanuts precision sowing problem
Peanut is one of the important economic crops and oil crops. The development and promotion of peanut production has become an effective way for farmers to increase income and increase agricultural efficiency. However, due to a variety of factors such as planting habits, seed quality, and sowing machinery in particular, for a long time, most regions are accustomed to extensive peanut seeding. According to statistics, the loss of seeds is as high as 20%. At the same time, due to irregular planting spacing and plant spacing, individual plant growth is relatively small and easy to pull up, and diseases, insect pests, lodging and other hazards are aggravated, which also greatly reduces peanut production.
In the field day field, Arpois air-suction precision seeder innovatively achieved accurate single-grain seeding of peanuts. After sowing, the on-site staff used special tools to measure and analyze the sowing effect. The plant depth, plant spacing, and row spacing adjusted according to Hebei's planting agrology all corresponded to the standard, and the sample area was not missed and broadcasted. “The biggest advantage of Absorption Precision Seeder is that it is precise and efficient. By changing the seed plate, you can achieve single seeding of granular seeds ranging from sesame seeds to peanuts. The exclusive patented EASY-SET system can quickly adjust the sowing line spacing. “Yang Yuanwu, head of sales for planting machines for agricultural equipment at Revoapoos, introduced it.
On-site experts said that the precise sowing of peanuts by Arbus air-suction precision seeder can make the plant evenly distributed, and nutrient distribution, light and moisture are more adequately distributed at the seedling stage, which is conducive to the cultivation of strong seedlings. At the same time, compared to conventional sown soya-beans, single-seed sowing can promote the growth of fine roots in peanut roots, significantly increase the total length of roots, and make nutrition more balanced throughout the growth process. Experiments have shown that single-seed sowing can increase the number of pods in peanuts, increase fruit weight and 100 kernel weight, and can achieve an increase of about 8% in the production of pods with an increase of 8% in the whole species. obvious.

Abs achieves efficient plant protection throughout crop growth
In this field day event, cabbage transplanting, operation technology demonstrations such as soybean, potato, peanut, and corn planting, and job skill training were carried out. The author found that each of the above-mentioned crops has an Abs product under operation during the cultivation process. They are the Apos series plant protection machinery.
From the transplanting of cabbage, the Arpoos ZP9500H self-propelled boom sprayer during the planting of peanuts and corn, to the Arpoos ZP81200 backpack sprayer after soybean and potato planting, the Loboa Persian agricultural equipment can already be used as the main foodstuff in China and Cash crops provide plant protection operations throughout the growth cycle.
“Food safety has received more and more attention from the whole society, especially the use of pesticides for cash crops is affecting everybody’s heart. The promotion of green prevention and control technologies, efficient and low-toxicity low-residue pesticides, and efficient plant protection machinery have become industry-wide and the whole society. "The consensus." Liu Wenzhong, head of sales and marketing at Albus Plant Protection Machinery, said, "In addition to the two products demonstrated today, Abs Plant Protection also has a traction air delivery product suitable for orchard operations. The advantages of a wide range of ground clearance and a wide variety of crop applications."
After the Apollo series of plant protection machinery worked on site, expert judges conducted analysis and analysis of the overall operation results. Experts agreed that the biggest advantage of the Apollo series of plant protection machinery lies in the uniform application of pesticides or fertilizers, as well as the savings in the amount of use. The overall operating results exceed those of well-known international brands.
It is understood that the Loboa Persian agricultural equipment adheres to the concept of "pharmaceutical application, reduction of control and harm reduction" sprayer product design concept, and develops a self-propelled spray boom with "safety, reliability, high efficiency, and environmental protection" characteristics. Sprayer, its key components sprayed abroad, sprinkler built-in anti-drip device, stop the spray nozzle without dripping; equipped with water backflow prevention device to prevent pesticides leaked to farmland or lakes, improve agricultural environmental safety; spray intelligent control, spray uniform, Compared with similar equipment in the market, it can save medication and use more than 8% of fat.
“This field day event is to adapt to the structural reform of the agricultural supply side as the theme and fully implement the key work of the Ministry of Agriculture Center for Agriculture and the Department of Agricultural Mechanization Management of the Ministry of Agriculture. The full range of products from Loboa Persian Agricultural Equipment participate in demonstrations and training throughout the course of the project and is believed to be mature. The Loewe products and the well-established Loewe program will surely provide all-round guarantees for the realization of mechanization and intelligence for the major grain and economic crops nationwide!†said Liang Qirong, party secretary of Lovol Heavy Industry.

Gate Valve is a opening and closing the gate assembly, perpendicular to the direction of movement and direction of flow of the gate, gate valve can be fully open and fully closed, discomfort door parameter varies, usually 5 degrees, the medium temperature is not high for 2 ~ 52 '. Improve the process, make up the sealing surface angle in the process of the deviation, which is called the gate.
Photo of our Gate Valve:
Movement mode
Gate valve closed, the sealing surface can only rely on media pressure to seal, that is, only rely on the media
Pressure to seal the sealing surface of the gate to the other side of the seat to ensure the sealing surface of the seal, which is self sealing. Most of the valve is forced to seal, that is, when the valve is closed, to rely on external force to force the gate to the seat, in order to ensure the sealing surface of the seal.
Movement: gate valve with the valve stem together for a straight line movement, also known as the gate valve. Usually on the lifting rod with trapezoidal thread, through the valve on the top of the nut and the body of the guide slot, the rotating motion into a linear motion, that is, the operating torque into the operating thrust. When the valve is opened, when the gate height is equal to 1:1 times the diameter of the valve, the fluid passage is completely free, but at the time of operation, the position can not be monitored. Actual use, is the apex of the stem as a sign, that is, the open position, as its fully open position. In order to consider temperature changes occur locked phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as a fully open valve position. Therefore, the valve fully open position, according to the location of the gate (that is, the stroke. Some gate valve stem nut is located on the gate, the hand wheel rotation to drive the valve stem rotation, and so that the gate to upgrade, this valve is called the rotating rod gate valve or called the dark bar gate valve.
Type
Domestic production of more than a number of manufacturers, the size of the connection is mostly not uniform. Mainly divided into the following categories: JB/T2203 - 1999 "gate structure length" of the general category. At present, most of the domestic safety valve manufacturers are in accordance with the standard design and production.
Manual gate valve working principle: turn the hand wheel, through the hand wheel and the stem of the thread into the back, enhance or decrease the valve plate connected with the stem, to achieve the role of opening and closing.
According to the shell / main material classification, gate valve can be divided into:
Metal material valve: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium valves, Monel valves, copper alloy valves, lead alloy valves.
Metal body lining valves: such as rubber lined valves, fluorine lined valves, lined with lead valves, plastic lined valves, lined with enamel valves.
Non metallic materials, such as ceramic valves, glass valves, plastic valves.
Advantage:
1, flow resistance is small. Body internal media channel is through, the media into a straight flow, flow resistance is small.
2, open and close when more effort. Is compared with the cut-off valve, because whether it is open or closed, the direction of movement of the gate and the direction perpendicular to the media flow.
3, a high degree of large, open and close for a long time. The opening and closing of the gate is larger, and the reduction is carried out through the screw.
4, water hammer phenomenon is not easy to produce. The reason is that the closure time is long.
5, medium can flow in any direction on both sides, easy to install. Gate valves are symmetrical on both sides of the channel.
6, the structure of the length (the distance between the two connecting end of the shell) is small.
7, the form is simple, the structure length is short, the manufacture craft is good, the scope of application is wide.
8. The structure is compact, the valve is rigid, the passage is smooth, the flow resistance is small, the sealing surface is made of stainless steel and hard alloy, and the service life is long, the sealing is reliable, the operation is light and flexible.
Disadvantages:
the sealing surface is easy to cause erosion and abrasion, maintenance is more difficult. Larger size, open requires a certain space, open and close for a long time. More complex structure.
Valve types: according to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate valve and is divided into: single gate type, dual gate plate and the flexible gate type; parallel gate valve can be divided into single gate plate and dual gate plate. According to the screw position of the valve stem can be divided into two kinds of the bright and dark bar gate valve.
Structure characteristics: general valve market has long been used widespread leakage or rusting phenomenon, the introduction of European high-tech rubber and valve manufacturing technology to produce elastic valve seat seal, valve seal to overcome the generally poor, rust and other defects, flexible seat seal gate valve with flexible gate generate tiny elastic deformation of compensation function to achieve a good sealing effect, the valve with a switch to compact, reliable sealing, elastic memory is good, and the use of life and other significant advantages. Can be widely used for water, sewage, construction, petroleum, chemical industry, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy systems, a body of pipeline regulation and closure devices as.
