Description

Technical Field

[0001] The invention relates to the technical field of sowing equipment, and in particular to a multifunctional corn film-covered seeder and a use method thereof. Background Art

[0002] Corn is a common coarse grain. Eating it in moderation usually provides nutrition and energy, promotes bowel movements, etc. It is cultivated throughout China and is widely grown in tropical and temperate regions around the world. It is an important cereal. Corn has strong drought resistance, cold resistance, and barrenness resistance, as well as excellent environmental adaptability. It has high nutritional value. Corn also has many biological activities, such as lowering blood sugar, improving immunity, and inhibiting and killing bacteria.

[0003] During the corn cultivation process, the traditional planting method uses hoes, shovels, manual seeders, etc. The disadvantages are high labor intensity, low efficiency, and poor sowing uniformity. Now corn sowing is usually carried out through modern agricultural machinery, which reduces people's labor intensity. Corn seeder is a kind of agricultural machinery specially used for corn planting. It can efficiently complete a series of operations such as trenching, sowing, fertilizing, and covering soil. The use of corn seeder has greatly improved the efficiency and uniformity of corn planting and reduced manual labor intensity.

[0004] During the corn sowing process, covering the soil can effectively maintain soil moisture and improve crop yield and quality. This has led to the development of a mulching seeder, which is an agricultural machinery that integrates sowing and mulching functions. It can complete multiple tasks such as furrowing, sowing, covering the soil, and laying ground film in one operation. This machinery has greatly improved the efficiency of agricultural production, especially in arid areas, providing people with great convenience. However, the existing mulching seeders have a fixed number of sowing rows during use, and cannot be properly adjusted according to different land conditions in different regions. If the number of sowing rows needs to be adjusted, the seeder can only be replaced, which delays the sowing efficiency. Therefore, it is very necessary to design a multifunctional corn mulching seeder and a method of using it that is highly practical and can switch the number of sowing rows. Summary of the invention

The film member 13, the film pressing member 14, the flattening member 15, the soil expelling member 16 and the duckbill seeder 17, the ditching member 12, the film covering member 13, the film pressing member 14, the flattening member 15, the soil expelling member 16 and the duckbill seeder 17 are sequentially arranged on the fixing seat 11, the auxiliary accessory 2 includes a connecting seat 21, a supporting member 22 and a soil dividing member 23, the supporting member 22 and the soil dividing member 23 are sequentially arranged on the connecting seat 21, and the soil dividing member 23 can push the soil in the middle position of the ditch after the ditching to both sides, so as to facilitate the soil expelling of the soil expelling member 16;

[0042] During use of the present application, the main sowing component 1 and the two auxiliary accessories 2 together form a sowing unit, and each sowing unit can perform independent sowing operations. A single sowing unit can perform furrowing, film covering, film pressing, flattening, soil division, soil shifting and sowing operations on ridges. It is functionally rich and sowing is smooth. The main sowing component 1 is the main core sowing component, which can perform furrowing, film covering, film pressing, flattening, soil shifting and sowing operations on ridges. The auxiliary accessories 2 are accessories of the main sowing component 1, which support and assist in soil division for the main sowing component 1. When both parties are assembled, corn sowing operations can be carried out smoothly. The main sowing component 1 and the auxiliary accessories 2 are connected in a detachable manner. On the premise of ensuring their stability, they can be conveniently disassembled and assembled, and connected. The connection method can be a mechanical connection, which is fixedly connected by tightening bolts. The position of the bolt fixing plate in this application has been indicated, and the corresponding position can be tightened by tightening bolts. At the same time, a positioning component can be added to the adjacent wall surface, which can be set as a positioning block and a positioning groove to help the sowing main component 1 and the auxiliary accessory 2 to better perform stable docking and prevent them from usurping their positions.

The electromagnetic device can be appropriately selected according to the needs, and it is a common technical means in the field of this technology, so it will not be described in detail here.

[0043] According to the demand for the number of corn sowing rows, multiple sowing units can be used in parallel to increase the number of furrowing rows and sowing rows. At the same time, they can be customized according to the sowing requirements, with a wider range of applications and more convenient use. In a single sowing trip, multiple sowing trips can be completed, and the sowing operation efficiency is high. Adjacent sowing units share one auxiliary accessory 2, that is, the auxiliary accessories 2 between adjacent sowing units are shared, which can reduce the use of materials, reduce the use cost, and simplify the connection method;

[0044] Specifically, the ditching member 12 includes a control plate 121, a threaded rod 122, a lifting plate 123, a guide rod 124, a limit plate 125, a connecting handle 126 and a plowshare 127. The threaded rod 122 is threadedly connected in the fixing seat 11. The control plate 121 is fixedly installed on the upper end of the threaded rod 122. The lifting plate 123 is movably installed on the lower end of the threaded rod 122. The guide rod 124 is mirror-imaged at the lower end of the fixing seat 11. The lower end of the guide rod 124 passes through the lifting plate 123 and is fixedly installed with the limit plate 125. The connecting handle 126 is mirror-imaged on the left and right sides of the lifting plate 123. The plowshare 127 is fixedly installed on the lower end of the connecting handle 126.

[0045] By turning the handle on the top of the control plate 121, the threaded rod 122 can be driven to rotate, and then the plowshare 127 can be lifted and lowered along the direction of the guide rod 124, so as to adjust the height of the plowshare 127 appropriately, so as to adjust the furrowing depth. The appropriate sowing depth helps to improve the germination rate of corn seeds and the survival rate of seedlings, thereby improving the overall yield of the crop. Too deep or too shallow sowing may lead to poor germination of seeds or even no germination. By adjusting the furrowing depth, the needs of the early growth of crops can be better met, thereby improving the final yield. At the same time, the flexibility of its use is increased, and it is convenient to make timely adjustments according to different operation requirements. There is no need to replace furrow openers of different specifications. Only simple adjustments can adapt to different operation requirements, which greatly improves the operation efficiency. At the same time, this also reduces the preparation time and labor intensity of the machinery.
