Description

A deep loosening shovel capable of cutting crop fibers

Technical Field

The invention relates to the technical field of soil deep loosening, in particular to a deep loosening shovel capable of cutting crop fibers.

Background technique

A subsoiler is an agricultural production tool, mainly used for subsoiling in farmland. The design and use of a subsoiler is to break up the bottom layer of the plow, increase the air permeability and water storage capacity of the soil, improve the soil structure, and facilitate the development of crop roots and the absorption and utilization of nutrients and water, thereby increasing the yield and quality of crops.

Traditional deep plowing shovels mostly have a rigid connection between the shovel head and the main body of the deep plowing equipment. When the deep plowing equipment is in operation, the shovel head needs to be inserted deep into the soil. When encountering stones or other hard obstacles, the rigidly connected shovel head will be subjected to strong impact and easily damaged, affecting its service life. In addition, when deep plowing the soil, traditional deep plowing shovels only plow out deep soil blocks, but cannot disturb the soil evenly. The soil is not finely broken, resulting in the shoveled soil blocks agglomerating, which is not conducive to the improvement of the overall soil structure.

Summary of the invention

The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a deep loosening shovel capable of cutting crop fibers, which can loosen the soil into finer pieces, and the shovel head is elastically arranged and is not easily damaged by rigid impact.

The technical scheme is as follows: A deep loosening shovel capable of cutting crop fibers comprises a mounting frame, a hollow frame, a crank frame, an elastic member, a shovel head and a side blade, wherein at least four hollow frames are fixedly arranged on the right part of the mounting frame, crank frames are slidably installed in all the hollow frames, and elastic members are arranged between the crank frames and the corresponding hollow frames, the shovel head is detachably installed on the right end of the crank frame, and the shovel head is arranged in a trapezoidal shape, with its tip tilted to the lower right, and the side blades are fixedly arranged on the front and rear side walls of the shovel head, and the side blades are also tilted to the lower right, and the inclination angle of the side blades is consistent with that of the tip of the shovel head;

The deep tillage shovel also includes a vibration mechanism, which includes a dual-axis motor, a mounting block, a straight shaft, a toggle wheel and a contact block I. A mounting block is fixedly arranged in the middle position of the right part of the mounting frame, and a dual-axis motor is horizontally mounted on the mounting block. A straight shaft is fixedly connected to each of the two output shafts of the dual-axis motor, and toggle wheels are arranged at the position of each crank frame corresponding to the two straight shafts. Contact block I is fixedly arranged on one side of all crank frames facing the toggle wheel, and the toggle wheel can contact and cooperate with the contact block I close to it.

Optionally, the toggle wheel is evenly provided with teeth along the circumferential direction, and when the toggle wheel rotates counterclockwise, the teeth will contact the corresponding contact blocks I in sequence and toggle the contact blocks I and the crank frame upwards.

Optionally, the deep plowing shovel also includes a crushing mechanism, which includes an arc frame, a synchronous shaft and a crushing blade. The lower part of all the crank frames is provided with a synchronous shaft that rotates through them, and both ends of the synchronous shaft are fixedly provided with an arc frame. The arc frame is a hollow structure, and a crushing blade is fixedly provided on the arc frame.

Optionally, the crushing mechanism further comprises a limit plate, and the limit plates are fixedly arranged on the front and rear side walls of the lower part of the crank frame, and the arc frame can contact the limit plates after rotating.

Optionally, the deep plowing shovel also includes a shaking mechanism, which includes a push rod, a contact block II and a torsion spring.

The cutting blade is spirally installed on the side wall of the roller.

Beneficial effects of the present invention:

After the shovel head of the present invention is inserted into the soil, under the joint action of the hollow frame, the crank frame and the vibration mechanism, the double-axis motor is started to drive the straight shaft and the toggle wheel to rotate, and the contact block I is rotated to make the crank frame slide up and down in the hollow frame. The shovel head will also shake up and down when loosening the soil. The front and rear sides of the shovel head are provided with side blades, which can assist the shovel head to shake up the shoveled soil blocks, and loosen the soil into finer pieces. The hollow frame and the crank frame are elastically connected. Even if the shovel head hits a hard stone during work, there is a certain space for buffering, thereby reducing the impact on it and extending its service life.

Through the setting of the crushing mechanism and the shaking mechanism, the large pieces of soil shoveled out by the shovel head will be crushed by the arc frame and the crushing blade, and while the crank frame slides up and down, the contact block II will reciprocate in contact with the top rod, and cooperate with the torsion spring to make the arc frame rotate back and forth to shake off the broken soil blocks, so as to avoid excessive soil blocks accumulating on the arc frame and affecting the subsequent crushing work;

Through the setting of the shredding mechanism, after the shovel head turns over the soil, the roller will immediately backfill the turned over soil to ensure the integrity of the field soil cover layer, which is beneficial to reduce soil erosion and maintain soil fertility. The cutting blade on the roller will chop the turned over plant roots and stems when rolling, and fill them back with the soil for composting.

In this way, the crank frame 3 will rise and fall reciprocatingly, and the shovel head 4 and the side blade 41 on the crank frame 3 will also rise and fall reciprocatingly. When descending, they will be inserted into the soil. When rising, the loosened soil will be brought out by the side blade 41. The soil will then fall on the arc frame 61 and slide down from the hollow part of the arc frame 61 after being crushed by the crushing blade 62. When the crank frame 3 rises, the contact block II 72 will also rise accordingly. , and is blocked by the push rod 71 on the way up. The push rod 71 then forces the contact block II 72 and the synchronous shaft 611 to rotate counterclockwise, and the arc frames 61 at both ends of the synchronous shaft 611 also rotate counterclockwise. The torsion spring 73 is compressed and stored at this time. When the crank frame 3 descends and resets, the contact block II 72 is disengaged from the push rod 71, the torsion spring 73 is restored, and the synchronous shaft 611 and the arc frame 61 are driven back to their original positions. In this way, the arc frame 61 will rotate periodically and shake off the remaining soil blocks during the rotation process to prevent the soil blocks from blocking its hollow part and loosening the subsequent soil. The limit plate 63 arranged on the crank frame 3 can limit the rotation angle of the arc frame 61 to prevent it from rotating too much and causing damage; the soil blocks turned out by the shovel head 4 and the side blade 41 will be rolled by the roller 82 after being crushed by the arc frame 61 and the crushing blade 62, and the soil will be backfilled to ensure the integrity of the field soil cover layer, and at the same time, the cutting blade 83 on the roller 82 will cut the plant roots and stems mixed in the soil during rotation, and then they will be backfilled together with the soil blocks through the roller 82 for composting, thereby enhancing soil fertility.
