DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0022] As Figures 1 - 4As shown in the figure, a device for stripping the soil of the agricultural tillage layer includes a support frame 1, a storage battery 15, and an electric control system. A vertical support arm 2 is fixed in the middle of the support frame 1, and a guiding arm 3 inclined downward to the left is fixed on the left part. A support shaft 4 extending forward is fixed at the bottom of the support arm 2. A handle 5 is fixed on the upper left part of the support frame 1. The front and rear parts of the support shaft 4 are coaxially and rotatably connected with main rollers 6 respectively. A lifting arm 7 is slidably connected to the guiding arm 3 along its inclined direction. A universal wheel is fixed at the bottom of the lifting arm 7. An electric drive telescopic mechanism for controlling the lifting arm 7 to reciprocally slide along the guiding arm 3 is jointly installed between the lifting arm 7 and the guiding arm 3. A support cylinder 10 parallel to the support shaft 4 is fixed at the lower right part of the support frame 1. An opening is radially penetrated through the upper part of the support cylinder 10, and an electric drive conveying mechanism for front and rear conveying is installed inside. A cylindrical transmission frame 12 is coaxially and rotatably connected to the outside of the support cylinder 10. A plurality of rows of stripping claws 13 arranged in the front and rear are fixedly arranged on the circumference of the transmission frame 12 at equal angles. The end of the stripping claw 13 far from the support cylinder 10 is bent counterclockwise in the frontal plane. An electric drive rotating mechanism is fixed to the support frame 1. The electric drive rotating mechanism is drivingly connected to the transmission frame 12 to drive the transmission frame 12 to rotate along the support cylinder 10. The electric drive telescopic mechanism, the electric drive conveying mechanism, the storage battery 15, and the electric control system are electrically connected. The electric control system is a known prior art, such as an industrial computer and a single-chip microcomputer During use, make the universal wheel and the main rollers 6 contact the ground, hold the handle 5 and manually push the device to move. Then use the electric drive rotating mechanism to drive the transmission frame 12 to rotate counterclockwise (observed from the front view angle), so as to use the stripping claws 13 to grab, break, and screen the soil, making the stones and the like inside it separate, and then enter the electric drive conveying mechanism inside the support cylinder 10 and be centrally transported to the front side of the support cylinder 10 to achieve preliminary stripping. When it is necessary to adjust the stripping depth of the stripping claws 13 for the soil, control the electric drive telescopic mechanism to appropriately extend and retract, so as to change the distance between the lifting arm 7 and the support frame 1, and then the depth of the stripping claws 13 relative to the soil can be changed, making the adjustment convenient and fast. The row-shaped stripping claws 13 have a larger stripping coverage area, thus improving the working efficiency.

[0023] The electric drive telescopic mechanism is an electric push rod 17. The electric push rod 17 is fixed to one of the guiding arm 3 or the lifting arm 7, and the push rod of the electric push rod 17 is fixed to the other of the guiding arm 3 or the lifting arm 7. The telescopic direction of the push rod of the electric push rod 17 is parallel to the direction in which the lifting arm 7 slides along the guiding arm 3.

[0024] Furthermore, by controlling the extension and retraction of the electric push rod 17, the position of the lifting arm 7 relative to the support frame 1 can be changed, so as to change the stripping depth of the stripping claws 13 for the soil.

[0025] The universal wheel includes a drive shaft 18, a bracket 19, a roller with a shaft 20, a first reduction motor 21, a worm 22, a servo motor 23, and a worm gear 24. A vertical drive shaft 18 is rotatably connected to the bottom of the lifting arm 7. A vertical bracket 19 is fixed to the bottom end of the drive shaft 18. A roller with a shaft 20 is rotatably connected to the bottom of the bracket 19 in the front-rear direction. A first reduction motor 21 extending in the front-rear direction is fixed to the front end of the bracket 19. The rotating shaft of the first reduction motor 21 is coaxially fixed to the roller with a shaft 20. A worm 22 is rotatably connected to the bottom of the guiding arm 3 in the front-rear direction, and a servo motor 23 is fixed to the front end of the bottom in the front-rear direction. The rotating shaft of the servo motor 23 is coaxially fixed to the worm 22. A worm gear 24 is coaxially fixed to the drive shaft 18. The worm 22 meshes with the worm gear 24. The first reduction motor 21 and the servo motor 23 are electrically connected to the electric control system.

[0026] Further, by controlling the rotation of the first reduction motor 21, the roller with a shaft 20 can be rotated, so that the manual pushing of the stripping device is changed to electric self-propulsion. By controlling the forward and reverse rotation of the servo motor 23, the rotation of the drive shaft 18 can be achieved by the meshing of the worm 22 and the worm gear 24, so as to indirectly change the angle between the axis of the roller with a shaft 20 and the support shaft 4, and then realize electric control steering, thereby improving work efficiency.

[0027] The storage battery 15 is fixed to the left part of the support frame 1. Two second support shafts 25 extending in the front-rear direction are fixed to the bottom of the guiding arm 3. The two second support shafts 25 are respectively located at the front and rear parts of the guiding arm 3 and are respectively rotatably connected to a foot pedal 26. Counterweight blocks 27 are respectively fixed to the left and right parts of the foot pedal 26.

[0028] Further, during the self-propelling process of the stripping device, a person can hold the handle 5 and step on the foot pedal 26, and then move along with it. While reducing the labor intensity, the self-propelling speed of the stripping device can be made faster without being affected by the walking speed of people, improving work efficiency. The position where a person stands and the position of the storage battery 15 can make the overall center of gravity of the stripping device shift to the lower left, thereby increasing the contact effect between the roller with a shaft 20 and the ground, making it more convenient to move on the ground, and at the same time being able to achieve the effect of "pressing the vehicle" to make the self-propelling more stable.

[0029] The electric drive rotating mechanism includes a second reduction motor 28, a gear 29, and an external gear ring 30. The second reduction motor 28 is fixed to the right rear part of the support frame 1. The rotating shaft of the second reduction motor 28 is coaxially fixed with a gear 29. The transmission frame 12 is coaxially fixed with an external gear ring 30. The gear 29 meshes with the external gear ring 30. The second reduction motor 28 is electrically connected to the electric control system.

[0030] Furthermore, by controlling the rotation of the second reduction motor 28, the driving frame 12 can be rotated by the engagement of the gear 29 and the external gear ring 30, thereby driving the stripping claws 13 to move circumferentially and realizing the stripping of the soil.

[0031] The conveying mechanism includes a speed-regulating motor 31, a lower crankshaft 32, a lower connecting rod 33, and a conveying hopper 34. A vertical speed-regulating motor 31 is fixed to the front of the support frame 1. The rotating shaft of the speed-regulating motor 31 is coaxially fixed with the lower crankshaft 32. The upper end shaft of the lower crankshaft 32 is coaxially fixed with the rotating shaft of the speed-regulating motor 31, and the lower end shaft is rotatably connected to the support frame 1. A horizontal lower connecting rod 33 is rotatably connected to the connecting rod journal of the lower crankshaft 32. A conveying hopper 34 is slidably connected back and forth in the support cylinder 10. The bottom end inner wall of the conveying hopper 34 is an inclined plane shape that is higher at the rear and lower at the front. The front upper part of the conveying hopper 34 is rotatably connected to the other end of the lower connecting rod 33 and penetrates through the front part. The rotating shaft of the speed-regulating motor 31 is electrically connected to the electronic control system.

[0032] Furthermore, by controlling the rotation of the speed-regulating motor 31, the lower crankshaft 32 can be driven to rotate, thereby driving the conveying hopper 34 to reciprocate back and forth along the support cylinder 10 through the lower connecting rod 33. And the bottom end inner wall of the conveying hopper 34 is in an inclined plane shape, so that the crushed stones falling into the conveying hopper 34 can move forward slowly and be discharged, which is convenient for centralized treatment.

[0033] The lower part of the support cylinder 10 penetrates downward. A plurality of support rollers 35 arranged in the front-rear direction are rotatably connected to the left and right parts of the inner wall of the support cylinder 10. The bottom end of the conveying hopper 34 is in rolling friction with each support roller 35. A plurality of sieve holes 36 penetrate through the upper and lower parts of the bottom of the conveying hopper 34.

[0034] Furthermore, during the reciprocating movement of the conveying hopper 34, the objects on it can be screened by using the sieve holes 36, which is convenient for the soil particles mixed in to be discharged through the sieve holes 36, thereby reducing the continuous mixing of soil and crushed stones, reducing the waste of soil caused by cleaning the crushed stones subsequently, and indirectly improving the overall working efficiency of soil stripping. And the use of the support rollers 35 can reduce the wear of the conveying hopper 34 during the reciprocating movement.

[0035] The type of the speed-regulating motor 31 is a double-shaft speed-regulating motor 31. A gear reducer 43 is fixed to the front part of the support frame 1. The input shaft of the gear reducer 43 is vertically downward, and the output shaft is horizontally forward. The bottom of the rotating shaft of the double-shaft speed-regulating motor 31 is coaxially fixed to the upper end shaft of the lower crankshaft 32, and the upper part of the rotating shaft is coaxially fixed to the input shaft of the gear reducer 43. The output shaft of the gear reducer 43 is coaxially fixed with an upper crankshaft 37. The rear end shaft of the upper crankshaft 37 is coaxially fixed to the output shaft of the gear reducer 43, and the front end shaft is in transmission connection with the support frame 1. A discharge hopper 39 extending in the front-rear direction is fixed to the front part of the support frame 1. The discharge hopper 39 penetrates and communicates with the front part of the support cylinder 10. A pressing seat 40 is slidably connected up and down to the discharge hopper 39. The pressing seat 40 and the upper connecting rod 38 are jointly provided with an upper connecting rod 38. The upper connecting rod 38 includes an upper rod body 44, a lower rod body 45 and a compression spring 46. The upper rod body 44 and the lower rod body 45 are slidably connected to each other along the extending direction of the upper connecting rod 38. The upper rod body 44 and the lower rod body 45 jointly fix a compression spring 46. The upper rod body 44 and the lower rod body 45 tend to move away from each other under the elastic repulsive force of the compression spring 46. The upper part of the upper rod body 44 is rotatably connected to the connecting rod journal of the upper connecting rod 38, and the lower rod body 45 is rotatably connected to the upper part of the pressing seat 40.

[0036] Furthermore, by the rotation of the double-shaft speed-regulating motor 31, the upper crankshaft 37 can be driven to rotate slowly at the same time, so as to drive the pressing seat 40 to move up and down slowly through the upper connecting rod 38. Then, the crushed stones slowly discharged from the conveying hopper 34 can be crushed by extrusion at the position of the discharge hopper 39, which is convenient for the subsequent collection and treatment of the crushed stones and improves the working efficiency. Due to the action of the compression spring 46, a certain movable margin is left between the upper rod body 44 and the lower rod body 45, so as to avoid damaging the double-shaft speed-regulating motor 31 due to the difficulty of crushing hard stones.

[0037] A ranging sensor 41 for downward ranging is rotatably connected to the rear part of the support 19. The virtual rotation axis of the ranging sensor 41 is coaxially arranged with respect to the support cylinder 10 and is electrically connected to the electric control system. The electric control system includes a display screen.

[0038] Furthermore, under the action of its own gravity, the ranging sensor 41 can always tend to be in a vertical state, so as to indirectly determine the height of the support cylinder 10 relative to the ground, and then display it through the display screen, so as to conveniently know the depth of the peeling claws 13 inserted into the soil and improve the working efficiency.

[0039] Reinforcing ribs 42 are jointly fixed between the peeling claws 13 in each row of the peeling claws 13. The reinforcing ribs 42 are close to the bent part of the peeling claws 13. The reinforcing ribs 42 and the peeling claws 13 are both in a shape of blade gathering in the counterclockwise direction in the front plane.

[0040] Furthermore, through the reinforcing rib 42, the overall structural strength of each stripping claw 13 can be improved, making the work of stripping soil more stable.

[0041] The above is a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, the changes, modifications, substitutions, and variations made to the embodiments still fall within the protection scope of the present invention.
