DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0018] Embodiment: A soil scarifier for agricultural planting, comprising Figure 1-3 As shown, the vehicle comprises a body 5 with motor-driven track wheels 1 mounted on either side of the body 5, ensuring stable travel in various soil conditions. A first motor 4 and a reducer 3 are mounted on the top of the body 5. The output shaft of the first motor 4 is connected to the reducer 3 to provide power. Rotating shafts 12 are located on either side of the reducer 3 to adjust the direction of power output. A pair of bearing mounts 11 are fixed to each end of the top front side of the body 5. Bearings are secured to these mounts. A crank 15 is secured to the end of the rotating shaft 12, which passes through one end of the bearing and is connected to the crank 15. A handle 6 is connected to the rear side of the top of the body 5. A second connecting rod 19 is hingedly attached to each side of the handle 6. Reinforcing ribs 13 are provided between the handle 6 and the body 5 to ensure structural stability. A connecting rod 14 is mounted on the top end of the handle 6. Bearings are secured to each end of the connecting rod 14, which is connected to the end of the second connecting rod 19 via bearings. The end of the second connecting rod 19 is hingedly connected to a connecting rod connector 18, which is hingedly connected to the end of the first connecting rod 16. The crank 15 is hingedly connected to the middle of the first connecting rod 16. A plowshare 8 is positioned between the first connecting rods 16. The front end of the plowshare 8 is wedge-shaped. The ends of the first connecting rods 16 are provided with fixing members 7. A fixing plate 17 is connected between the fixing members 7. The fixing plate 17 has several sets of threaded holes 26 that connect to the plowshare 8. The plowshare 8 is fixed to the front end of the fixing plate 17 via the threaded holes 26 and bolts.

[0019] The rear end of the vehicle body 5 is equipped with a rotary tillage assembly 9, which houses a rotary tiller wheel 10. The assembly 9 includes a cutter wheel housing 20 fixed to the rear end of the vehicle body 5. Cutter wheel housing 20 is flanked by cutter wheel sleeves 21, which fit over both ends of the rotary tiller wheel 10. A baffle 22 is provided at the rear end of the cutter wheel housing 20. A pulley housing 23 is located in the middle of the upper side of the cutter wheel housing 20, and a pulley 24 is located within the pulley housing 23. A second motor 25 is located on one side of the pulley 24 and is electrically connected to a control circuit board. The central portion of the rotary tiller wheel 10 passes through the lower end of the pulley 24, and is driven by the pulley 24. The rotary tiller wheel 10 is equipped with multiple sets of rotary blades 2. Driven by the pulley 24 and the second motor, the blades rotate at high speed, improving soil loosening efficiency.

[0020] Through the linkage design of the first motor 4, the speed reducer 3, and the crank-connecting rod, the plowshare 8 can efficiently turn the soil, improving the efficiency of loosening the soil and the quality of tillage. By providing the crawler wheel 1, combined with the plowshare 8 and the rotary tilling blade 2, the tiller can adapt to different terrains while completing soil loosening, turning, and crushing operations, greatly improving the efficiency of farmland management. In addition, the rotary tillage assembly 9 of the device achieves efficient rotation of the rotary tillage wheel 10 through the cooperation of the pulley 24 and the second motor, and the rotary tillage blade 2 can more thoroughly crush the soil, improving the soil's air permeability and water retention.

[0021] Working process

[0022] After startup, the first motor 4 serves as the power source, and its output shaft is connected to the speed reducer 3. The speed is reduced and the torque is increased by the speed reducer 3, which transmits power to the crawler wheel 1, driving the tiller forward. The rotating shaft 12 at both ends of the speed reducer 3 is connected to the crank 15. The rotation of the rotating shaft 12 drives the crank 15, which then drives the fixed plate 17 at the front end to move up and down through the first connecting rod 16 and the connecting rod connector 18, thereby realizing the tillage of the soil by the plowshare 8. The second motor is connected to the rotary tiller wheel 10 shaft via a pulley 24, providing power to the rotary tillage assembly 9. The rotary tiller wheel 10 shaft is equipped with multiple rotary tillage blades 2. When the second motor is started, the pulley 24 drives the rotary tiller wheel 10 shaft to rotate, and the rotary tillage blades 2 rotate at high speed, further crushing and loosening the soil after being plowed by the plowshare 8. The handle 6 is used to manually control the direction and forward and backward movement of the tiller to adapt to different soils and tillage requirements.

[0023] In summary, the utility model can adapt to different terrains and has the advantages of simple structure, easy use, high efficiency and durability.
