[0004] In existing technologies, rotary tillers are generally used, which use a rotating motor to rotate loosening blades to loosen the soil. However, relying solely on the blades to cut through the soil in a circular motion results in poor soil transport efficiency and can place an excessive load on the rotating motor when the soil is hard. Summary of the Invention
[0005] Based on the technical problems in the background technology, the present invention proposes a soil loosening machine for environmentally friendly agricultural production.
[0006] This invention proposes a soil loosening machine for environmentally friendly agricultural production, comprising a frame with wheels at both ends, a lifting frame at the bottom of the frame, a fixed tube fixed to the bottom of the lifting frame, a rotating cylinder rotatably mounted outside the fixed tube, and a loosening component slidably mounted within the rotating cylinder in a circular array of slots. Multiple cuts are provided at the ends of the loosening component away from the rotating cylinder. A connecting frame is fixed to the outer wall of the loosening component near the fixed tube, and springs connect the two ends of the connecting frame to the inner wall of the rotating cylinder. A hydraulic cylinder is vertically mounted in the middle of the fixed tube, and a pressure block is connected to the bottom of the hydraulic cylinder. The top of the pressure block can fit against the outer wall of the fixed tube, and the thickness of the pressure block gradually decreases from the middle towards both sides.
[0007] Preferably, magnetic blocks are installed on both sides of the fixing tube outside the pressure block, and the magnetic blocks are magnetically attracted to the loosened part away from the cut head.
[0008] Preferably, a hydraulic telescopic rod is installed on the side of the lifting frame. The telescopic shaft of the hydraulic telescopic rod extends upward to the top of the lifting frame. The top end of the telescopic shaft of the hydraulic telescopic rod is fixed to the bottom of the frame. A vertically downward extending limit rod is fixed at the bottom of the frame away from the hydraulic telescopic rod. A through hole is provided on the lifting frame to slide in contact with the limit rod.
[0009] Preferably, both ends of the rotating cylinder are equipped with cover plates, and a rotating ring is fixed at a position away from the rotating cylinder on the cover plate. The inner wall of the rotating ring slides in contact with the outer wall of the fixed tube. A rotating motor is fixed at one end of the lifting frame, and a gear is fixed on the output shaft of the rotating motor. The outer wall of one of the rotating rings is configured as a ring tooth structure that meshes with the gear.
[0010] Preferably, the loosened part has notches on both sides corresponding to the cutting head, the notches are set near the end of the cutting head, and a blade is fixed on the inner wall of the notch, the blade is set parallel to the extension direction of the cutting head.
[0011] Preferably, the loose part has multiple equally spaced perforations on both sides above the slot.
[0012] Preferably, the two ends of the loosened part slide in contact with the inner walls of the two ends of the through groove, and the inner walls on both sides of the through groove are fixed with limit plates. An airbag is fixed on the limit plate toward the position of the loosened part, and the two sides of the loosened part are in contact with the airbag.
[0013] Preferably, multiple extension blocks are installed on both sides of the connecting frame, and a movable rod is installed at the bottom end of the extension block. A movable cylinder is slidably connected to the bottom of the outer wall of the movable rod.
[0014] Preferably, the bottom end of the movable cylinder is sealed, and the bottom end of the movable cylinder is configured as an outwardly arched arc structure, and the bottom end of the movable rod is fixed with a piston that is slidably connected to the inner wall of the movable cylinder.
[0015] Preferably, a connecting pipe is provided between the bottom end of the outer wall of the movable cylinder and the airbag at the corresponding position, and the connecting pipe is configured as a flexible tube.
[0016] The beneficial effects of this invention are as follows:
[0017] 1. In this invention, the loosening effect on the soil is improved by the movable setting of the loosening component and the setting of the pressure block connected to the hydraulic cylinder, and the load on the motor driving the rotating drum is effectively reduced, thereby increasing the service life of the equipment during long-term loosening operations.
[0018] 2. In this invention, during the operation of loosening soil by rotating the loosening component and moving radially along the rotating cylinder, after the cutting head breaks the soil, the blade in the slot helps to disperse the soil. As the depth of the loosening component changes, the soil broken at the upper and lower positions is dispersed through the perforations distributed above, thereby improving the soil dispersion and loosening effect.
[0019] 3. In this invention, while the loosening component can move radially in the rotating cylinder, it can also swing between the two airbags. The swinging motion of the loosening component improves the crushing and loosening effect at the bottom contact position. On the other hand, the swinging motion of the loosening component can avoid direct hard compression causing excessive load on the rotating motor position, thereby further improving the loosening operation effect and extending the service life of the equipment.
[0020] 4. In this invention, as the connecting frame and the loosening component are pressed down to a greater depth, the movable rod moves the piston toward the bottom of the movable cylinder, thereby inflating the airbag and increasing the squeezing force of the airbag on the side of the loosening component. Through the displacement of the movable rod with the loosening component and the setting of the airbags on both sides of the loosening component, the loosening effect of the loosening component on the soil during rotation and movement is improved.

Detailed Implementation
[0031] Example 1: Refer to Figures 1-7 A soil loosening machine based on environmentally friendly agricultural production includes a frame 1, with tire frames 2 installed at both ends of the frame 1, and wheels 3 installed at the bottom of the tire frames 2. A lifting frame 4 is installed at the bottom of the frame 1 between the two wheels 3. A horizontally placed fixed pipe 5 is fixed to the bottom of the lifting frame 4. A rotating cylinder 6 is rotatably installed outside the fixed pipe 5. The rotating cylinder 6 has a ring-shaped array of grooves on its outer side. A loosening component 7 is slidably installed in the grooves. Multiple cuts 701 are provided at the end of the loosening component 7 away from the rotating cylinder 6. The end of the loosening component 7 away from the cuts 701 extends into the rotating cylinder 6, and there is a gap between the end of the loosening component 7 away from the cuts 701 and the outer wall of the fixed pipe 5. A connecting frame 8 is fixed to the outer wall of the loosening component 7 near the fixed pipe 5. Springs 9 are connected between the two ends of the connecting frame 8 and the inner wall of the rotating cylinder 6. The springs 9 are located at the position of the connecting frame 8 away from the fixed pipe 5. A hydraulic cylinder 10 is vertically installed in the middle of the fixed pipe 5. The extension axis of the hydraulic cylinder 10 is downward. Extending to the bottom of the fixed pipe 5, the bottom end of the hydraulic cylinder 10 is connected to a pressure block 11. The top of the pressure block 11 can fit against the outer wall of the fixed pipe 5. The thickness of the pressure block 11 gradually decreases from the middle position to both sides. When loosening, the lifting frame 4 lowers with the rotating cylinder 6 and multiple loosening parts 7, so that the frame 1 moves with the wheel 3. The rotating cylinder 6 rotates in the same direction as the wheel 3 and the rotation speed of the rotating cylinder 6 is greater than that of the wheel 3, so that the loosening parts 7 contact the ground in the forward direction of movement to carry out loosening operations. For example, the wheel rotates counterclockwise, causing the frame 1 to move from right to left. The rotating cylinder 6 also rotates counterclockwise, causing the loosening parts 7 to descend from the left side to contact the ground. As the frame continues to move to the left, the loosening parts 7 continuously rotate downward to insert into the ground until the loosening parts 7 rotate to the right side to realize the soil conveying operation. By moving the loosening parts 7 in the same direction and at a different speed as the wheel 3, the load on the rotating cylinder 6 can be reduced while ensuring the loosening operation.
[0032] Furthermore, during the soil loosening operation, as the loosening component 7 rotates downwards, the hydraulic cylinder 10 reciprocates, causing the pressure block 11 to alternately impact the top of the loosening component 7. Due to the thickness difference of the pressure block 11, the loosening component 7 experiences increasing downward pressure as it rotates downwards from its forward direction. This improves the loosening effect in harder soil by continuously penetrating downwards through impact. In softer soil, the spring 9, combined with the reciprocating motion of the loosening component 7 during rotation, further enhances the loosening effect. Thus, the movable design of the loosening component 7 and the pressure block 11 connected to the hydraulic cylinder 10 improve the soil loosening effect and effectively reduce the load on the motor driving the rotating cylinder 6, thereby extending the equipment's service life during prolonged loosening operations.
[0033] In this invention, magnetic blocks 12 are installed on both sides of the fixed tube 5 located on the pressure block 11. The magnetic blocks 12 are magnetically attracted to the loosening component 7 at a position away from the cutter head 701. Before the loosening component 7 rotates to a position close to the pressure block 11, that is, before the cutter head 701 contacts the ground, it is first moved towards the rotating cylinder 6 by magnetic attraction. Then, when it moves away from the magnetic blocks 12 and close to the pressure block 11, the cutter head 701 is inserted into the soil surface and penetrates deeply under the simultaneous action of the spring 9 and the pressure block 11. This improves the insertion and conveying effect of the loosening component 7 on the soil surface, avoids relying solely on rotational force for insertion, thereby reducing the equipment load and improving the long-term effectiveness of the equipment. Furthermore, when the loosening component 7 rotates to the tail position, magnetic attraction is used to assist in pulling the loosening component 7 upward. At the same time, the change in magnetic force causes the loosening component 7 to move radially upward along the rotating cylinder 6 during the rotation and loosening of the soil, thereby further improving the loosening operation effect.
[0034] In this invention, a hydraulic telescopic rod 17 is installed on the side of the lifting frame 4. The telescopic shaft of the hydraulic telescopic rod 17 extends upward to the top of the lifting frame 4. A through hole 1 corresponding to the telescopic shaft of the hydraulic telescopic rod 17 is provided on the lifting frame 4. The inner diameter of the through hole 1 is larger than the outer diameter of the telescopic shaft of the hydraulic telescopic rod 17. The top end of the telescopic shaft of the hydraulic telescopic rod 17 is fixed to the bottom of the frame 1. In this way, when the hydraulic telescopic rod 17 extends its telescopic shaft, the lifting frame 4 can move downward relative to the frame 1. A vertically extending limiting rod 18 is fixed at the bottom of the frame 1 away from the hydraulic telescopic rod 17. A through hole 2 that slides in contact with the limiting rod 18 is provided on the lifting frame 4 to maintain the vertical lifting and lowering of the lifting frame 4 and the stability during the operation.
[0035] In this invention, cover plates 13 are installed at both ends of the rotating cylinder 6. An opening adapted to the fixed tube 5 is provided in the middle of the cover plate 13, and the inner wall of the opening slides in contact with the outer wall of the fixed tube 5. A rotating ring 14 is fixed to the cover plate 13 away from the rotating cylinder 6, and the inner wall of the rotating ring 14 slides in contact with the outer wall of the fixed tube 5. An annular protrusion 141 is provided on the inner wall of the rotating ring 14. An annular groove 501 is provided on the outer wall of the fixed tube 5 at a position corresponding to the protrusion 141. The protrusion 141 and the groove 501... The wall sliding contact is explained as follows: the cover plate 13 and the rotating ring 14 are constructed by splicing two plates, which facilitates the assembly and disassembly of the cover plate 13. A rotating motor 15 is fixed at one end of the lifting frame 4, and a gear 16 is fixed to the output shaft of the rotating motor 15. The outer wall of one of the rotating rings 14 is set as a ring tooth structure that meshes with the gear 16, so that the rotating motor 15 drives the rotating ring 14 and the rotating cylinder 6 to perform circumferential rotation, and facilitates the cleaning, maintenance or replacement of parts inside the rotating cylinder 6.
[0036] In this invention, slots 19 are provided on both sides of the loosening component 7 at positions corresponding to the cutting head 701. The slots 19 are opened near the end of the cutting head 701. A blade 20 is fixed on the inner wall of the slot 19. The blade 20 is arranged parallel to the extension direction of the cutting head 701. Multiple equally spaced perforations 21 are provided on both sides of the loosening component 7 above the slots 19. During the operation of loosening the soil by rotating the loosening component 7 and moving radially along the rotating cylinder 6, the cutting head 701 breaks the soil and the blade 20 in the slots 19 assists in dispersing the soil. The thickness difference between the surface of the loosening component 7 and the position of the slots 19 is used to disperse the local soil. During the change of the pressing depth of the loosening component 7, the soil broken at the upper and lower positions is dispersed through the perforations 21 distributed above, thereby improving the soil dispersion and loosening effect.
[0037] Example 2: Refer to Figures 1-9 A soil loosening machine based on environmentally friendly agricultural production, based on embodiment 1, has two ends of the loosening component 7 slidingly contacting the inner walls of the two ends of the trough. Limiting plates 22 are fixed on both sides of the inner walls of the trough. Airbags 23 are fixed to the positions of the limiting plates 22 toward the loosening component 7. The two sides of the loosening component 7 are in contact with the airbags 23. Under the action of the spring 9 connecting the loosening component 7, the loosening component 7 can move radially in the rotating cylinder 6, and the loosening component 7 can also swing between the two airbags 23. When the cutting head 701 encounters a harder position, the loosening component 7 can deflect with the bottom end of the cutting head 701 as the rotation point as it continues to rotate and moves with the frame 1. On the one hand, the swinging of the loosening component 7 improves the crushing and loosening effect on the bottom contact position. On the other hand, the swinging nature of the loosening component 7 can avoid direct hard compression causing excessive load on the rotating motor 15, thereby further improving the loosening operation effect and extending the service life of the equipment.
[0038] In this invention, multiple extension blocks 801 are installed on both sides of the connecting frame 8. A movable rod 24 is installed at the bottom end of the extension block 801. A movable cylinder 25 is slidably connected to the bottom of the outer wall of the movable rod 24. The bottom end of the movable cylinder 25 is sealed and has an outwardly arched arc structure. A piston 26 is fixed to the bottom end of the movable rod 24 and slidably connected to the inner wall of the movable cylinder 25. A connecting pipe 27 connects the bottom end of the outer wall of the movable cylinder 25 with the corresponding airbag 23. The movable cylinder 25 is only connected to the airbag 23 on the same side through the connecting pipe 27. The connecting pipe 27 is a flexible hose structure. An opening corresponding to the position of the connecting pipe 27 is opened on the limiting plate 22. During use, the bottom end of the movable cylinder 25 and the inner wall of the rotating cylinder 6 are connected by a... However, with the sliding contact, as the connecting frame 8 and the loosening component 7 are pressed down deeper, the movable rod 24 moves the piston 26 towards the bottom of the movable cylinder 25, thereby inflating the airbag 23 and increasing the squeezing force of the airbag 23 on the side of the loosening component 7. When the loosening component 7 is inserted into a relatively shallow soil layer, the loosening component 7 is less restricted by the resistance between the two airbags 23, and the swing amplitude is larger, which can disperse the surface soil. When the loosening component 7 is inserted into the soil at a greater depth, the resistance on both sides of the loosening component 7 increases and the swing amplitude decreases, so that the loosening component 7 can break the soil below more stably. Thus, through the displacement of the movable rod 24 with the loosening component 7 and the setting of the airbags 23 on both sides of the loosening component 7, the loosening effect of the loosening component 7 on the soil during rotation and movement is improved.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
