Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a soybean sowing device for saline-alkali land. Background Art

[0002] Soybean planters are usually mechanically or hydraulically driven and can automatically complete operations such as furrowing, sowing, and covering soil. They can adjust the sowing depth and row spacing according to different soil conditions and sowing requirements to ensure that soybean seeds reach the best planting state in the soil. Especially when planting soybeans in saline-alkali land, the survival rate of soybeans can be improved by planting in deep furrows and shallow covers.

[0003] For example, the Chinese utility model patent disclosed in the publication number CN208638917U: a precision soybean seeder, which drives the forward component forward and further drives the sowing device forward through the driving component. Each seeder is used to sow a row of land. The grooving component, the sowing component, the covering component and the power component are supported by the supporting component. The grooving component first opens a sowing groove on the ground. The power component provides power for differential sowing of the sowing component. The sowing component sows one soybean seed each time for differential sowing. Therefore, the sowing spacing of the soybean seeds is completely dependent on the rotation of the first motor to drive the first driving gear to rotate. The first driving gear drives the first The chain further drives the first driven gear to rotate, and then drives the second rotating shaft to rotate. The rotation of the second rotating shaft will drive the second driving gear to rotate, and further drive the rotating gear and the first rotating shaft to rotate. The rotation of the first rotating shaft will drive the suction plate and the material distribution plate to rotate. The suction holes on the suction plate can absorb the soybean seeds. This application cannot adjust the planting spacing of soybeans according to the actual needs of planting. Therefore, if the sowing spacing is too dense, the nutrient competition between soybean plants will intensify, which may cause some plants to develop poorly or even die, because the nutrients in the soil are not enough to support the healthy growth of all plants, especially when the nutrients in saline-alkali soil are insufficient.

[0023] A gear 14 is fixedly installed at one end of the first rotating shaft 7, and a distributing wheel 17 is fixedly installed on the first rotating shaft 7 located in the distributing box 6. The outer side of the distributing wheel 17 has a plurality of grooves. Through the arrangement of the first rotating shaft 7 and the distributing wheel 17, the seeds in the silo 4 can be quantitatively transported to the lower material pipe 8 in a quantitative manner. A plurality of mounting grooves 18 are provided on the outer side of the driving wheel 15, and two first limit blocks 19 are fixedly installed on both sides of the mounting groove 18. A plurality of first card slots 20 and second card slots 21 are provided on one side of the driving wheel 15, and a single first card slot 20 and a single second card slot 21 are a group. A slot 22 is provided at the center position of the driving tooth 16, and a connecting screw 25 is inserted in the slot 22. Limiting slots 23 are provided on both sides of the driving tooth 16, and a telescopic slot 24 is also provided on the side of the driving tooth 16 away from the second sprocket 12, and a limiting rod 26 is movably installed in the telescopic slot 24. 6 is inserted and installed in the corresponding installation groove 18, and one end of the connecting screw 25 is threadedly connected to the screw groove at the bottom of the installation groove 18.

[0024] It should be noted that the utility model is a soybean sowing device for saline-alkali land. When the main frame 1 is pulled by the vehicle and the connecting frame 3, the main frame 1 moves in the planting area through the roller 2, and the slotting component 5 synchronously performs slotting and soil covering operations on the planting area. At the same time, the transmission wheel 10 also rotates on the soil layer in the planting area, so that the transmission wheel 10 drives the first sprocket 11 to rotate, so that the first sprocket 11 drives the second sprocket 12 to rotate through the chain, and then the second sprocket 12 drives the driving wheel 15 to rotate through the second rotating shaft 13.

Therefore, the first rotating shaft 7 cooperates with the distribution wheel 17 located in the distribution box 6 to distribute the soybean seeds into the feeding pipe 8 and cover the soil through the slotting component 5 for planting;

[0025] When it is necessary to control the unloading cycle of the dividing wheel 17, the multiple driving teeth 16 on the outside of the driving wheel 15 can be adjusted at intervals. First, the limiting rod 26 on the side of the corresponding driving tooth 16 is pulled to one side, so that one end of the limiting rod 26 equipped with the rubber ring 28 can be pulled out from the corresponding first slot 20. Then, the corresponding driving tooth 16 can be pressed into the installation slot 18, and the driving tooth 16 can be moved on the telescopic slot 24 through the slot 22 and the compression spring can be compressed toward the bottom of the installation slot 18. When the driving tooth 16 is completely received in the installation slot 18, the limiting rod 26 can be pushed toward the driving wheel 15, so that one end of the limiting rod 26 is installed in the corresponding second slot 21 through the two rubber rings 28, thereby completing the limiting of the received driving tooth 16. The rotation cycle of the driving gear 14 can be controlled by adjusting the spacing of the multiple driving teeth 16, thereby controlling the rotation cycle of the first rotating shaft 7 and the dividing wheel 17.
