Description

Technical Field

[0001] The utility model relates to the field of soil crust breaking, in particular to a surface soil crust breaker for plastic film wheat. Background Art

[0002] Plastic film wheat cultivation refers to a cultivation technique in which, after land preparation and ridging, the whole ground is covered with plastic film, and then hole sowing is carried out on the ridges. This technique effectively solves the prominent problems of the occurrence of stems under the film and weed damage, simplifies the technical operation procedures, and greatly reduces the labor cost. This technique integrates yield-increasing elements such as rainwater collection, temperature increase, and soil moisture conservation, greatly improves the precipitation utilization efficiency, and can also be extended to other close-planting crops and water-saving furrow irrigation on the film in irrigation areas, and has great popularization and application prospects in arid and semi-arid regions and irrigation areas.

[0003] During the planting process, especially in wheat fields, in some areas, strong precipitation occurs after sowing, resulting in serious crusting of the surface soil covered with plastic film, which hinders the normal emergence of wheat. Traditional breaking methods mostly use a drum-type breaker with external cutter heads for operation. During the rotary breaking process, the cutter heads are prone to sticking to the soil. When they come into contact again and attempt to break the compacted soil under the plastic film, the stuck soil may cause significant damage to the plastic film, thereby affecting the growth environment and yield of wheat.

[0008] As an improvement of the above technical solution, the counterweight block is a magnetic block, and the magnetic force of the counterweight block is less than the gravity of the sum of the blade and the counterweight block.

[0009] The beneficial effects of the present utility model are as follows: During the rotation of the device, the recycling of the blade enables the soil adhering to the surface of the blade to fall off by itself, preventing damage to the plastic film again, affecting its effect, and hindering the growth of wheat. An installation groove is provided inside the rotating cylinder at one end of the protruding groove. A blocking block is arranged inside the installation groove, and a connecting strip is arranged inside the blocking block and is fixedly connected to the rotating shaft through an arc groove, so that the blocking block will not be displaced with the rotation and always remains below, which can block the blade located below and damage the soil plate.

Detailed Embodiments

[0014] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] Please refer to Figures 1-3, the present utility model provides a technical solution: a surface soil crust breaker for plastic film wheat, which includes a fixed shaft 10. Handles 11 are installed on the outer periphery of both sides of the fixed shaft 10. Turntables 13 are arranged at both ends of the fixed shaft 10. Wheels 12 are rotatably arranged on the outer periphery of the turntables 13; a rotating shaft 20 is rotatably installed on the outer periphery of the middle of the fixed shaft 10. A rotating cylinder 21 is rotatably arranged on the outer periphery of the rotating shaft 20. An extending groove 22 is formed on the surface of the rotating cylinder 21. A limiting groove is arranged inside the extending groove 22. A counterweight block 23 is arranged in the limiting groove formed inside the extending groove 22. A blade 24 is fixedly installed on one side of the counterweight block 23. An installation groove 25 is formed inside the rotating cylinder 21 at one end of the extending groove 22. A blocking block 26 is arranged inside the installation groove 25. An arc groove is formed on the outer peripheral surface of the rotating cylinder 21. A connecting strip is arranged inside the blocking block 26 and is fixedly connected to the rotating shaft 20 through the arc groove.

[0016] In this implementation scheme, through the rotation of the rotating cylinder 21 combined with the inertial force of the counterweight block 23, the blade 24 can cut into the soil more powerfully during the rotation process, effectively breaking the compacted surface soil. At the same time, the design of the limiting groove ensures the stability of the counterweight block 23 and the blade 24 during the rotation process, preventing loosening or falling off. During the rotation process, the blade 24 can be retracted so that the soil adhering to the surface of the blade 24 can fall off by itself, preventing damage to the plastic film again, affecting its effect, and hindering the growth of wheat. An installation groove 25 is formed inside the rotating cylinder 21 at one end of the extending groove 22. A blocking block 26 is arranged inside the installation groove 25. A connecting strip is arranged inside the blocking block 26 and is fixedly connected to the rotating shaft 20 through the arc groove, so that the blocking block 26 will not displace with the rotation and always remains below, and can play a blocking role on the blade 24 located below to break the soil slab.

[0017] Specifically, a groove is formed inside the turntable 13. A fixed block 32 is arranged inside the turntable 13. A spring 31 is arranged on the outer periphery of the fixed block 32. A connecting block 30 is arranged at one end of the spring 31. The connecting block 30 is arranged on the outer periphery of the fixed block 32.

[0018] In this implementation scheme, through the groove formed inside the turntable 13, the fixed block 32 arranged inside the turntable 13, the spring 31 arranged on the outer periphery of the fixed block 32, and the connecting block 30 arranged at one end of the spring 31 and on the outer periphery of the fixed block 32, the rotating cylinder 21 of the device can always fit for the land with uneven bottom surface, and the crushing effect of the device will not be affected by the uneven bottom surface.

[0019] Specifically, a counterweight groove 33 is formed on one side of the rotating cylinder 21. A fixed column 34 is arranged inside the counterweight groove 33. The counterweight groove 33 is closed by a quick-release cover.

[0020] In this implementation scheme, the design of the counterweight groove 33 and the quick-release cover makes the adjustment or replacement of the counterweight block 23 simple and fast. Users can adjust the weight of the counterweight block 23 according to different soil conditions to achieve the best crushing effect, improving the flexibility and adaptability of the equipment.

[0021] Specifically, balls are arranged inside the rotating cylinder 21, and both the inner and outer sides of the rotating cylinder 21 are rotatably connected.

[0022] In this implementation scheme, the design of the balls reduces the friction and resistance during the rotation of the rotating cylinder 21, making the rotation of the rotating cylinder 21 smoother.

[0023] Specifically, the counterweight block 23 is a magnetic block, and the magnetic force of the counterweight block 23 is less than the gravity of the blade 24 plus the counterweight block 23.

[0024] In this implementation scheme, by controlling the magnetic force to be less than the gravity of the blade 24 plus the counterweight block 23, it is ensured that the blade 24 can cut into the soil stably and powerfully during the crushing process, improving the crushing effect. At the same time, the blade 24 can be better recovered inside when it is above, and the adhered soil can fall off.

[0025] The working principle and usage process of the present utility model: When using the surface soil hardening crusher for plastic film wheat, first hold the handle 11 tightly, place the rotating wheel 12 on the ground surface, start the rotation, the rotating cylinder 21 rotates with the rotating shaft 20, the counterweight block 23 drives the blade 24 to cut powerfully into the hardened soil to achieve crushing. As it rotates, the soil on the blade 24 is blocked and falls off by itself inside its recovery device, avoiding damage to the plastic film next time. The spring 31 structure inside the turntable 13 adapts to the uneven ground to ensure the crushing effect. If the counterweight needs to be adjusted, the quick-release cover can be quickly opened to increase or decrease the counterweight block 23 to complete the operation.

[0026] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it.
