Description

Technical Field

[0001] This invention pertains to agricultural machinery and mainly relates to a crop stubble crushing device using a variable-direction disc cutter composite magnetic spraying tower for root clearing. Background Technology

[0002] If corn stubble is not thoroughly crushed, it will affect the quality of plowing and land preparation, and it will not decompose quickly after being returned to the field, thus affecting the efficiency of subsequent sowing. Existing crop stubble crushing devices have low accuracy in crushing stubble and a large amount of soil is disturbed during root crushing, resulting in serious soil moisture loss. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned technical problems by developing a crop stubble crushing device with a variable-direction disc cutter and a composite magnetic spraying tower for root clearing. This device achieves automatic variable-angle stubble cutting while simultaneously driving the magnetic tower forward. The magnetic tower always operates in the shallow soil layer below the surface, effectively impacting and spraying pesticides on the underground roots as it moves, thus achieving efficient stubble crushing while minimizing the exposure of the topsoil. The invention achieves this objective as follows: A crop stubble crushing device with a variable-direction disc cutter and a composite magnetic spraying tower for root clearing, characterized in that: the device includes an outer shell, with a triangular connecting frame at the front of the outer shell; a stubble-cutting mechanism is installed inside the outer shell, and an underground root-clearing mechanism is installed outside the outer shell.

[0004] The cutting mechanism includes a first support, a second support, a motor, a disc cutter, and a camera. The upper ends of the first and second supports are fixed to the outer casing via a first rotating device and a second rotating device, respectively. The outer casing has grooves, and the ends of the first and second supports are slidably installed within these grooves. The motor includes a first motor, a second motor, a third motor, a fourth motor, a fifth motor, and a sixth motor. The first motor and the first support are fixedly connected via a second combined rotating shaft. One end of the second combined rotating shaft is fixed to a second pull rod, and the other end is fixed to the main shaft of the third motor. The fourth motor and the second support are fixedly connected via a fourth combined rotating shaft. One end of the fourth combined rotating shaft is fixed to a fourth pull rod, and the other end is fixed to the sixth motor. The first and second rotating devices are each rotatably mounted on a short shaft by two fixed blocks. The short shafts of the fixed blocks are fixed to the first and third combined rotating shafts, respectively. The main shaft of the motor is fixedly mounted to the first combined rotating shaft, driving the first combined rotating shaft to rotate. The main shaft of the fifth motor is fixedly mounted to the third combined rotating shaft, driving the third combined rotating shaft to rotate. The first and third combined rotating shafts are respectively driven by the first and second gearboxes. The disc cutter includes a first variable-direction shaving disc cutter and a second variable-direction shaving disc cutter, which are respectively fixedly mounted on the first and second lead screws, and also fixedly mounted to the first and fourth motors respectively. The number and spacing of the cutters can be changed according to the actual situation by using washers for limiting. The camera is fixed to the front end of the outer casing. The camera on the right side of the machine's forward direction is connected to the first and third controllers, which control the third and sixth motors respectively. The third and sixth motors are respectively connected to the first and second batteries. At the same time, the camera on the left side is connected to the second and fourth controllers, which control the second and fifth motors respectively. The second and fifth motors are respectively connected to the first and second batteries.

[0005] The underground root clearing mechanism includes a magnetic double-layer spraying pyramid and a deep loosening shovel. A magnetic block is installed on the triangular connecting frame, which can move the magnetic double-layer spraying pyramid along the machine's movement direction. The deep loosening shovel is fixed to the frame. The magnetic double-layer spraying pyramid includes an outer magnetic spraying pyramid and an inner magnetic spraying pyramid. Each of the four inclined layers of the magnetic double-layer spraying pyramid is equipped with a triangular lifting plate. The outer magnetic spraying pyramid has a spray nozzle, and the inner magnetic spraying pyramid has slots on each side and rotating shafts on its four bottom sides. The inner magnetic spraying pyramid contains an electric pump connected to a fifth controller. The fifth controller is connected to a third battery, and the fourth battery is connected to a seventh motor, which is connected to the fifth controller. By controlling the lifting of the lifting plates, the amount of pesticide sprayed is controlled. This constitutes a crop root stubble clearing device using a variable-direction disc cutter composite magnetic spraying tower.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention mainly includes a stubble-cutting mechanism and a root-cleaning mechanism. The stubble-cutting mechanism uses a camera to observe the stubble and adjusts the angle of the blades parallel and perpendicular to the stubble according to the actual situation, so as to achieve efficient variable-angle stubble cutting and improve the crushing effect. In addition, based on the distribution characteristics of underground roots, the shape of the magnetic double-layer spraying pyramid is designed, which reduces the frequency of soil emergence and entry, reduces the amount of soil disturbed, and does not damage the surface soil when operating in shallow soil layers. It has a good moisture retention effect, and at the same time, the drug accelerates the root decomposition rate and cleans up the residual roots in the soil. Attached Figure Description

This constitutes a crop root stubble crushing device with a variable direction disc cutter composite magnetic spraying tower for clearing roots.

[0019] During operation, after the camera 24 observes the shape characteristics of the stubble, the second controller 27 controls the second motor 7 to rotate. The second motor 7 transmits power to the first support 1 through the first combined rotating shaft 9 and the first gearbox 43, causing the first pull rod 3 to slide in the groove on the outer shell 37, thus changing the angle of the first variable-direction stubble cutting disc blade 5 parallel to the stubble.

The effect of changing the angle perpendicular to the stubble is achieved by the third controller 30 controlling the rotation of the sixth motor 23. The sixth motor 23 inputs power to the fourth pull rod 16 through the fourth combined rotating shaft 21, causing the fourth pull rod 16 to slide in the groove on the second bracket 13, thus completing the cutting in a specific direction and achieving the effect of changing the angle perpendicular to the stubble. The magnetic block 32 drives the magnetic double-layer spraying pyramid to move along the direction of the machine's movement. The fifth controller 35 controls the forward and reverse rotation of the main shaft of the seventh motor 40. Through the transmission of the gearboxes of the three identical spraying mechanisms on the inner spraying pyramid 42, the bottom rotating shafts on all four sides of the inner spraying pyramid 42 rotate simultaneously, causing the lifting plate 39 to slide in the slot. The fifth controller 35 controls the switch of the electric pump 33. The electric pump 33 causes the medicine in the interlayer of the magnetic double-layer spraying pyramid to be sprayed out from the nozzles on the four inclined surfaces of the magnetic outer spraying pyramid 36, impacting the roots while achieving controllable amount of spraying, thereby achieving the effect of clearing the roots.
