[0017] The present invention also provides a sowing method of a soil loosening and sowing device for wheat planting, comprising the following steps:

[0018] S1: First, the device is moved to the position where sowing is required, and then the wheat seeds required for sowing are added into the storage bin. The operator steps on the right fender to climb onto the device and sits on the seat near any operating part, and controls the rotating plate to rotate clockwise based on the rotating shaft. With the cooperation of pulley 2 and belt 2, the gear drives the toothed plate to move to the right, so that the guide wheel can be against belt 1, and then belt 1 and the two pulleys can be kept in a taut state. Then, the operating part controls the adjustment motor to drive the worm to rotate, so that the worm wheel drives the screw sleeve to rotate.

In the process of the device moving automatically, the driving shaft can be controlled to rotate with the cooperation of pulley 1 and belt 1, so that the wheat seeds in the storage bin can be evenly transported to the sowing legs through the telescopic hose. Since the sowing legs are deeply embedded in the soil, the wheat seeds enter the specified depth in the soil, thereby completing the sowing operation;

[0020] S3: After one sowing is completed, the lifting plate is controlled by the electric cylinder to move upward, so that the loosening teeth and the sowing legs move upward to a state of being out of contact with the soil, and then the steering motor is used to control the rotation of the U-shaped frame on the right side, so as to complete the steering of the device.

[0021] Compared with the prior art, the present invention provides a soil loosening and sowing device for wheat planting and a sowing method thereof, which have the following beneficial effects:

[0022] 1. By adjusting the coordinated use of the motor and the worm gear mechanism, the sowing depth can be accurately controlled, so that the wheat seeds can be sown into the soil at a predetermined depth, thereby improving the uniformity of sowing and the germination rate of the wheat seeds.

[0023] 2. The design of the transmission assembly enables the device to keep the belt in a taut state during movement, ensuring the stable rotation of the drive shaft, thereby ensuring the continuous and uniform transportation of wheat seeds and avoiding the problem of uneven sowing caused by loose belts.

[0024] 3. The setting of the operating components enables the operator to easily control the entire sowing device, improves the convenience and efficiency of operation, and reduces the labor intensity of the operator.

[0025] 4. The design of the linkage assembly enables the movement of the gear and the toothed plate to accurately control the tension of the belt 1 and the pulley 1, thereby ensuring the transmission stability between the moving wheel and the driving shaft and improving the reliability and service life of the device.

[0026] 5. The design of the U-shaped frame and the slider provides a stable guide for the lifting plate, ensuring the stability and accuracy of the sowing legs in the soil, while allowing the right U-shaped frame to perform steering movements, improving the flexibility and adaptability of the device.

[0027] 6. The setting of the loosening component enables the soil to be loosened effectively before sowing, creating a good soil environment for the germination and growth of wheat seeds and improving the sowing effect.

[0028] 7. The sowing device of the present invention has a compact structure, is easy to operate, can adapt to sowing operations under different terrains and soil conditions, and has high practicality and promotion value.

[0029] In summary, the present invention provides an efficient, precise, and easy-to-operate soil loosening and sowing device for wheat planting and a sowing method thereof, which can significantly improve the efficiency and quality of sowing operations, and at the same time can well adapt to wheat sowing operations in different situations when separated from traction equipment, and has good application prospects.

[0044] This embodiment also provides a sowing method of a soil loosening and sowing device for wheat planting, comprising the following steps:

[0045] S1: First, move the device to the position where sowing is required, and then add the wheat seeds required for sowing into the storage bin 2. The operator steps on the right mudguard to climb onto the device and sits on the seat 6 near any operating part 63, and controls the rotating plate 62 to rotate clockwise around the rotating shaft 61. With the cooperation of the pulley 2 73 and the belt 2 74, the gear 72 drives the toothed plate 7 to move to the right, so that the guide wheel 71 can be against the belt 1 51, and then the belt 1 51 and the two pulleys 1 5 can be kept in a taut state.

[0046] S2: Start the motor 13 through the operating part 63, and the motor 13 controls one of the moving wheels 12 to rotate. With the cooperation of the other moving wheels 12, the device can move automatically. After moving to the sowing position, the electric cylinder 32 is controlled to extend through the operating part 63, so that the lifting plate 3 moves downward, and the motor 2 43 is started at the same time. The motor 2 43 drives the plurality of loosening teeth 42 to rotate rapidly around the mounting roller 41 through the mounting roller 41. As the lifting plate 3 descends, the loosening teeth 42 contact the soil and loosen the soil. The depth of loosening the soil can be easily adjusted by controlling the extension length of the electric cylinder 32. In the process of the self-movement of the device, the driving shaft 201 can be controlled to rotate with the cooperation of the pulley 1 5 and the belt 1 51, so that the wheat seeds in the storage bin 2 can be evenly transported to the sowing legs 22 through the telescopic hose 21.

At the same time, motor 2 (43) is started, and the motor 2 (43) drives a plurality of loosening teeth (42) to rotate rapidly around the mounting roller (41) through the mounting roller (41), so that the loosening teeth (42) rotate rapidly around the mounting roller (41), and the lifting plate (3) is lowered. The teeth (42) contact the soil and loosen the soil. The depth of the loosening can be easily adjusted by controlling the extension length of the electric cylinder (32). During the self-movement of the device, the driving shaft (201) can be controlled to rotate under the cooperation of the pulley (5) and the belt (51), so that the wheat seeds in the storage bin (2) can be evenly transported to the sowing legs (22) through the telescopic hose (21). Since the sowing legs (22) penetrate deep into the soil, the wheat seeds enter the soil to a specified depth, thereby completing the sowing operation. S3: After one sowing operation is completed, the lifting plate (3) is controlled by the electric cylinder (32) to move upward, so that the loosening teeth (42) and the sowing legs (22) move upward to a state where they are out of contact with the soil, and then the steering motor (14) is used to control the right U-shaped frame (11) to rotate, thereby completing the steering of the device. After the steering is completed, the device is driven to another position where sowing is required, and then the above operation is repeated to perform the sowing operation again.
