Description

Technical Field

[0001] The utility model relates to the technical field of tillage equipment, in particular to wheat tillage equipment. Background Art

[0002] In the agricultural field, wheat is one of the most widely grown food crops in the world. With the accelerated advancement of agricultural mechanization, the design and innovation of wheat farming equipment has become the key to improving agricultural production efficiency, reducing costs and increasing crop yields.

[0003] After searching, a utility model with announcement number CN219205216U provides a wide-width sowing device for wheat cultivation, involving the technical field related to sowing devices. The wide-width sowing device for wheat cultivation includes a material box, a strip sliding hole is opened at the bottom of the material box, and at least three plow legs are slidably connected to the strip sliding hole. The top of each plow leg is fixedly connected to a funnel that is slidably fitted with the inner wall of the material box, and a connecting soft plate that is slidably fitted with the inner wall of the material box is fixedly arranged between each adjacent two funnels. When in use, the guide plate is driven to move up and down by controlling the telescopic driving device. The up and down movement of the guide plate drives the connecting rods to have different inclination angles through the rotating shaft to drive the plow legs to move. During this period, the rotating shaft in the card slot will slide along the card slot, so that the adjacent plow legs are brought close or away, and then the spacing between the adjacent plow legs is adjusted, so that the sowing width can be adjusted according to the usage situation to avoid affecting the seed growth quality and the planting yield, thereby improving its practicability.

[0004] The wide-width sowing device for wheat cultivation described above still has some shortcomings in actual use:

[0005] When the device adjusts the distance between the plow legs, it is necessary to pull the guide plate up and down through the telescopic drive device to adjust the distance between the plow legs. This adjustment method requires that the weight of the guide plate and the connecting part under the guide plate be all added to the telescopic drive device, increasing the burden borne by the telescopic drive device. At the same time, the guide plate is only moved up and down through the telescopic drive device, and cannot be effectively fixed, and the stability is relatively poor. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings in the prior art that the weight of the guide plate and the connecting parts below the guide plate are all added to the telescopic drive device, increasing the burden borne by the telescopic drive device, and the guide plate is only moved up and down by the telescopic drive device, cannot be effectively fixed, and has relatively poor stability, and a wheat tillage equipment is proposed to solve the shortcomings.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A wheat farming equipment comprises an H-shaped bracket, and a material box is fixedly installed on the top of the H-shaped bracket, and the sides of the two H-shaped brackets close to each other are rotatably connected to rotating wheels, and a truss is fixedly connected inside the H-shaped bracket. A two-way screw rod is rotatably penetrated inside the truss, and one end of the two-way screw rod extends to one side of the H-shaped bracket. One side of the truss is provided with a plurality of connecting rods, and the connecting rods are cross-placed. The rotation of the two-way screw rod can drive the cross-placed connecting rods to adjust the distance.

[0009] In a possible design, a sliding block is fixedly connected inside the truss, and the sliding block is rotatably sleeved on the outer wall of the bidirectional screw rod. A plurality of nuts are slidably connected inside the truss, and the plurality of nuts are threadedly sleeved on the positive and negative threaded sections of the outer wall of the bidirectional screw rod. One side of the plurality of nuts and sliding blocks is fixedly connected to a second connecting shaft, and one end of two adjacent connecting rods is cross-sleeved on the outer wall of the second connecting shaft. A connecting block is provided on one side of the connecting rod, one side of the plurality of connecting blocks is fixedly connected to a first connecting shaft, and the other ends of the plurality of connecting rods are correspondingly sleeved on the outer wall of the first connecting shaft.

[0010] In a possible design, one side of the connecting block is fixedly connected to the pulling block, and the pulling block is slidably sleeved on the outer wall of the arm leg.

[0011] In a possible design, a plurality of movable grooves are provided in the H-shaped bracket, a limiting groove is provided in the movable groove, a limiting ring is provided on the outer wall fixing sleeve of the arm leg, and the limiting ring is slidably connected to the limiting groove.

[0012] In a possible design, a connecting frame is provided on one side of the material box and the H-shaped bracket, and a connecting hole is provided in the connecting frame, and the connecting hole can be connected to the agricultural equipment.

[0013] In a possible design, a rotating handle is fixedly mounted on one end of the bidirectional screw rod, and the bidirectional screw rod can be driven to rotate by rotating the handle.

[0014] In the present application, when the handle is turned to drive the bidirectional screw rod to rotate, due to the positive and negative thread design of the bidirectional screw rod, the nut will move relatively along its axial direction, and the movement of the nut drives the connecting rod to cross-rotate through the second connecting shaft, thereby changing the spacing between the connecting rods. The other end of the connecting rod is fixed by the first connecting shaft and the connecting block to ensure the stability and reliability of the entire adjustment mechanism. At the same time, the movable groove, the limiting groove, and the limiting ring are combined to limit the movement of the arm leg, thereby playing a limiting role on the arm leg.

[0015] Beneficial effects:

[0016] In the utility model, the wheat tillage equipment can flexibly adapt to the cultivation requirements of different wheat varieties or terrains by adjusting the spacing of the connecting rods, thereby achieving precise sowing or tillage;

[0017] In the utility model, the wheat tillage equipment described in the utility model has an internal limiting mechanism, a moving groove, a limiting groove, and a limiting ring, which can limit the movement of the legs, thereby not only ensuring the stability of the movement of the legs, but also ensuring the stability of the legs during tillage;

[0018] In the utility model, not only the distance adjustment of the legs is realized, but also the stability and reliability of the entire adjustment mechanism are ensured through the support and coordination of the truss and the H-shaped bracket, thereby extending the service life of the equipment.
