Detailed implementation manners

[0018] It is easily understood that according to the technical solution of the present invention, without changing the essential spirit of the present invention, those of ordinary skill in the art can propose various interchangeable structural forms and implementation manners. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0019] According to an embodiment of the present invention in combination with Figures 1-5 And Figure 8 As shown, a pull-out type farmland weeding device includes: a movable vehicle frame 1, an adjusting member 2 is arranged inside the movable vehicle frame 1, a weeding mechanism 3 for weeding is arranged below the adjusting member 2, the weeding mechanism 3 includes an outer housing 31, a lifting member 32 is arranged inside the outer housing 31, and the bottom end of the outer housing 31 is rotatably connected to an inner housing 33; The lifting component 32 includes a motor 321 fixedly connected to the inner wall of the outer housing 31. The output end of the motor 321 is fixedly connected to a lead screw 322. An inner disk 323 is threadedly connected to the outside of the lead screw 322. An outer disk 324 is rotatably connected to the outside of the inner disk 323. An activity groove 325 is formed on the outside of the outer disk 324. A weeding component 36 is arranged inside the activity groove 325. The bottom end of the lead screw 322 is fixedly connected to a rotating disk 39. An arc groove 391 is formed on the upper surface of the rotating disk 39. A spring rod 38 is fixedly connected to the bottom surface of the outer disk 324. The spring rod 38 is arranged corresponding to the arc groove 391. After aligning the position where the grass needs to be pulled out, the motor 321 is started. The lead screw 322 is driven to rotate by the motor 321, so that the inner disk 323 and the outer disk 324 vertically move downward along the direction of the lead screw 322. At the same time, the weeding component 36 also moves downward. The weeding component 36 is used to insert around the soil of the grass that needs to be removed. As the outer disk 324 further moves downward, the spring rod 38 gradually approaches the rotating disk 39 and inserts into the arc groove 391. Under the rotation action of the rotating disk 39, the spring rod 38, the outer disk 324 and the weeding component 36 are synchronously driven to rotate, so as to realize shoveling up all the soil around the grass, and the root of the grass is also included in this piece of soil, achieving the effect of removing the root system. Subsequently, the motor 321 reverses, driving the inner disk 323 and the outer disk 324 to move upward completely, completing the weeding work of pulling out the grass.

[0020] To further solve the problems of the device that it cannot converge to the middle when shoveling up and the firmness when the bucket inserts into the soil, according to the embodiments of the present invention in combination with Figures 1-11 As shown, the weeding component 36 includes a connecting short rod 361 rotatably connected inside the activity groove 325.

There are four groups of the weeding component 36 and the activity groove 325. The four groups of the weeding component 36 and the activity groove 325 are arranged at equal intervals correspondingly. During the downward movement of the outer disk 324, the connecting short rod 361 and the vertical plate 363 are synchronously driven to move downward, and the bucket 364 is used to complete the work of inserting into the soil. The connecting short rod 361 and the torsion spring 362 provide conditions for the bucket 364 to move closer to the middle subsequently.

[0021] A compression groove is formed inside the vertical plate 363, and a locking component 37 is arranged inside the compression groove. There are two groups of locking components 37, and the two groups of locking components 37 are symmetrically arranged on both sides of the vertical plate 363. The locking component 37 includes a spring A372 fixedly connected to the inner wall of the compression groove. One end of the spring A372 is fixedly connected with a movable plate 371. The movable plate 371 is slidably connected inside the compression groove. A magnetic convex block 373 is fixedly connected to one side of the movable plate 371. A top shell 326 is fixedly connected to the upper surface of the outer plate 324. The top shell 326 is correspondingly arranged with the movable groove 325. A clamping groove corresponding to the magnetic convex block 373 is formed on the inner wall of the top shell 326. During the downward movement of the vertical plate 363, the magnetic convex block 373 is clamped inside the clamping groove, so as to realize the stable vertical movement of the vertical plate 363 when it moves downward, and ensure stable insertion into the soil.

[0022] An inner frame 334 is fixedly connected to the inner wall of the inner shell 33, and a magnetic block 335 is fixedly installed on the inner wall of the inner frame 334. The inner frame 334 is correspondingly arranged with the top shell 326, and the magnetic block 335 and the magnetic convex block 373 are magnetically repulsive. After the vertical plate 363 moves downward and the bucket 364 has been inserted into the soil, the top shell 326 moves downward between the inner frames 334. By using the magnetic repulsion between the magnetic block 335 and the magnetic convex block 373, the magnetic convex block 373 is compressed into the compression groove. At this time, the vertical plate 363 can rotate, providing conditions for subsequent rotational excavation.

[0023] A T-shaped groove 332 is formed on the inner wall of the inner shell 33. The T-shaped groove 332 is correspondingly arranged with the vertical plate 363. The magnetic convex block 373 is adapted to the inside of the T-shaped groove 332. A bottom ring 34 is fixedly connected to the bottom surface of the inner shell 33, and an outer inclined block 341 is fixedly connected to the inner wall of the bottom ring 34. The outer inclined block 341 is correspondingly arranged with the bottom surface of the vertical plate 363. During the downward movement of the vertical plate 363, by using the corresponding extrusion between the bottom surface of the vertical plate 363 and the outer inclined block 341, the bottom ends of the buckets 364 are rotated and converged towards the middle until one side of the vertical plate 363 contacts the inner wall of the T-shaped groove 332. The magnetic convex block 373 pops out under the action of the spring A372 and is clamped inside the T-shaped groove 332. At this time, the bottom ends of the four buckets 364 all converge towards the middle, and cooperate with the arc groove 391 to contact and resist the spring rod 38, driving the whole to rotate, which is convenient for subsequent shoveling of the soil.

[0024] An inner inclined block 333 is fixedly connected to the top surface of the inner wall of the T-shaped groove 332. The inner inclined block 333 is correspondingly arranged with the magnetic convex block 373. During the subsequent process of the motor 321 driving the lead screw 322 to reverse and the outer plate 324 moving upward, the inner inclined block 333 is used to squeeze the magnetic convex block 373 to make it contract back into the compression groove. Under the restoring force of the torsion spring 362, the vertical plate 363 is driven to reset and the magnetic convex block 373 pops out again after resetting and is inserted into the clamping groove to complete the fixation. This process is used to move the uprooted grass to other positions for easy collection.

[0025] A limiting inner ring 3231 is fixedly connected to the outer side of the inner disc 323. An empty groove is formed in the inner wall of the outer disc 324. The limiting inner ring 3231 is rotatably connected in the empty groove. A limiting outer ring 331 is fixedly connected to the outer side of the inner housing 33. A rotating groove 311 is formed in the inner wall of the outer housing 31. The limiting outer ring 331 is rotatably connected inside the rotating groove 311. When the inner disc 323 moves up and down, the limiting inner ring 3231 drives the outer disc 324 to lift and lower synchronously. When the magnetic bump 373 is clamped inside the T-shaped groove 332, the rotation of the outer disc 324 drives the inner housing 33 to rotate synchronously.

[0026] A fixed disc 35 is fixedly connected to the inner wall of the outer housing 31. A limiting rod 351 is fixedly connected to the bottom surface of the fixed disc 35. The limiting rod 351 penetrates through the inner disc 323. A collar 352 is fixedly connected to the bottom surface of the limiting rod 351. The collar 352 is sleeved on the outer side of the lead screw 322. Through the settings of the fixed disc 35, the limiting rod 351 and the collar 352, the stable lifting of the inner disc 323 is ensured.

[0027] The adjusting component 2 includes an electric telescopic rod 21 fixedly connected to one side of the movable vehicle frame 1. One end of the electric telescopic rod 21 is fixedly connected with an adjusting block 23. The bottom surface of the adjusting block 23 is fixedly connected to the upper surface of the outer housing 31. A guide rod A22 is arranged inside the movable vehicle frame 1. The guide rod A22 penetrates through the adjusting block 23. When performing horizontal position adjustment, the electric telescopic rod 21 is turned on to drive the adjusting block 23 to move along the guide rod A22, so as to realize the horizontal position displacement of the outer housing 31.

[0028] A controller 11 is fixedly connected to one side of the movable vehicle frame 1. An industrial camera 12 is fixedly connected to the bottom surface of the movable vehicle frame 1. The controller 11 is electrically connected to the industrial camera 12, the electric telescopic rod 21 and the motor 321. The industrial camera 12 is controlled by the controller 11 to perform positioning analysis on the position where weeding is required, and then the weeding work is completed through the cooperation of the electric telescopic rod 21 and the motor 321.

[0029] Specifically, when weeding, the industrial camera 12 is controlled by the controller 11 to perform positioning analysis on the position where weeding is required. The electric telescopic rod 21 is activated to drive the adjusting block 23 to move along the guide rod A22, thereby realizing the horizontal position displacement of the outer housing 31. After aligning with the position where weeding is required, the motor 321 is activated. The motor 321 drives the lead screw 322 to rotate, so that the inner disk 323 and the outer disk 324 vertically move downward along the direction of the lead screw 322. Through the settings of the fixed disk 35, the limit rod 351 and the collar 352, the stable lifting of the inner disk 323 is ensured. During the downward movement of the outer disk 324, the connecting short rod 361 and the vertical plate 363 are synchronously driven to move downward. The bucket 364 is used to insert into the soil. After the top shell 326 moves down between the inner frames 334, the magnetic block 335 and the magnetic convex block 373 repel magnetically, compressing the magnetic convex block 373 into the compression groove. Then, the bottom surface of the vertical plate 363 and the outer inclined block 341 are correspondingly squeezed, so that the bottoms of the four buckets 364 rotate and converge towards the middle until one side of the vertical plate 363 contacts the inner wall of the T-shaped groove 332. The magnetic convex block 373 pops out under the action of the spring A372 and is clamped inside the T-shaped groove 332. At this time, the bottoms of the four buckets 364 all converge towards the middle, and the spring rod 38 gradually approaches the rotating disk 39 and inserts into the arc groove 391. Under the rotation action of the rotating disk 39, the spring rod 38, the outer disk 324 and the weeding assembly 36 are synchronously driven to rotate, so as to realize shoveling all the soil around the grass; Subsequently, the motor 321 rotates in reverse, driving the inner disk 323 and the outer disk 324 to move upward completely. During the upward movement of the outer disk 324, the inner inclined block 333 is used to squeeze the magnetic convex block 373 to make it contract back into the compression groove. Under the restoring force of the torsion spring 362, the vertical plate 363 is driven to reset and the magnetic convex block 373 pops out again after resetting and inserts into the card slot to complete the fixation, thereby realizing the loosening of the weeded grass and completing the weeding work.
