[0002] In municipal garden projects, tree transplanting is a common and important link. Common tools include shovel-type devices. The current traditional tree transplanting devices take up a large space. When transplanting trees to a distant place, too many resources will be occupied during transportation. When not in use, a large storage space is required, which wastes resources and is not convenient to carry.

[0003] The patent announcement number is CN111789013B, which is a tree transplanting device for municipal gardens. It relates to the technical field of tree transplanting, and includes a mounting rod that connects the vibration device and the tree transplanting device. It also includes a pressure block, a first return spring, a top block, a balance spring, a transmission shell, a protective shell, a connection shell, a support slat, a swing pin and a shovel, etc., wherein a pressure block, a first return spring, a top block and a balance spring are installed in the sliding cavity in the transmission shell from top to bottom in sequence, and the transmission shell guides the movement of the pressure block and the top block; when the shovel in the present invention encounters tree roots or bricks and stones, the shovel with sharp serrations at the lower end forms a high-frequency repeated sawing and shearing function for the encountered tree roots and bricks, thereby making it easier to cut off thicker tree roots or bricks and stones, shortening the time of tree transplanting, and improving the work efficiency of tree transplanting.

[0004] The above-mentioned tree transplanting device for municipal gardens, when in use, although it repeatedly saws and shears tree roots and bricks at a high frequency by setting a vibration device, it occupies a large space and is inconvenient to carry and store, and the sharp bladed saw teeth may also cause harm to personnel in unexpected situations.

[0015] The present invention provides a tree transplanting device for municipal gardening, which has the following beneficial effects:

[0016] 1. The present invention provides a folding device. When the device is in working state, the connecting rod moves downward through the threaded groove and the fixing nut, pushing the shovel blade to rotate around the first rotating shaft, so that the shovel blade fits the grip rod, thereby reducing the size of the device, making it easy to carry when transplanting trees, and taking up less storage space when not in use. At the same time, after rotation, the sharp part of the shovel blade is close to the grip rod, reducing the risk of accidental injury; and when the shovel blade is used and unfolded, the foot pedal can be unfolded through the cooperation of the limit block, so that people can do shoveling operations by stepping on the foot pedal conveniently.

[0017] 2. The present invention provides a mud removal device. When the device is in working state and needs to be used, the half-tooth rotates, and the scraper block moves through the cooperation of the slider and the slide groove, and the large pieces of mud on the blade are scraped off by the scraper block, so as to keep the blade clean and facilitate subsequent shoveling operations; at the same time, when the half-tooth rotates, the teeth of the half-tooth squeeze the protruding block, and the compression spring is in a compressed state through the cooperation of the striking rod and the compression spring, so that the striking rod is knocked out, and the blade is knocked to make the blade vibrate, so that the mud at the scraper block can be quickly dropped from the blade, thereby improving the cleaning efficiency.

[0018] 3. The present invention provides a scraping device. When the semi-rotating tooth rotates, the rotating rod at its front end moves synchronously, so that one end of the third connecting rod is subjected to force and squeezes the other end of the third connecting rod. When the other end of the third connecting rod is squeezed, the third connecting rod pushes the rotating rod to move, which pushes the transmission block to move and slide on the front end of the foot pedal, so that the scraping block moves synchronously at the upper end of the foot pedal, and the soil on the surface of the foot pedal is removed, so as to prevent the wet soil from reducing the friction between the foot pedal and the sole, thereby reducing the work efficiency; and when the foot pedal is rotated and folded, the relatively sticky soil attached to the bottom side wall of the shovel blade can be pushed away through the cooperation of the hinged rod, the hinged seat, the movable seat and the push plate, and fall from the side wall of the shovel blade, so as to prevent the soil on the bottom side wall of the shovel blade, which may be relatively sticky and inconvenient to fall, and adhere to the side wall of the shovel blade for a long time, which may easily cause the shovel blade to rust.

When the short rod 307 moves downward, the inner wall of the first connecting rod 308 is squeezed, so that one end of the first connecting rod 308 is subjected to a downward force and rotates around the other end, so that the first rotating shaft 6 rotates synchronously, driving the connecting frame 7 fixedly connected thereto to rotate. When the connecting frame 7 rotates, it drives the shovel 8 to rotate synchronously. The outer end of the connecting frame 7 is rotationally connected to the inner end of the foot pedal 309. The outer end of the connecting frame 7 is fixedly connected to one end of the torsion spring 310, and the other end of the torsion spring 310 is fixedly connected to the inner side of the foot pedal 309.

[0029] When the present embodiment is working: when the blade 8 is not needed to be used, the fixing nut 305 is rotated to rotate and move downward around the threaded shaft. When the fixing nut 305 moves downward, the connecting rod 302 is driven to move downward. When the connecting rod 302 moves downward, the short rod 307 fixedly connected thereto is driven to move downward synchronously. When the short rod 307 moves downward, the inner wall of the first connecting rod 308 is squeezed, so that one end of the first connecting rod 308 is subjected to a downward force and rotates around the other end. When the first connecting rod 308 rotates, the first rotating shaft 6 fixedly connected thereto rotates synchronously. When the first rotating shaft 6 rotates, it drives the connecting frame 7 fixedly connected thereto to rotate. When the connecting frame 7 rotates, it drives the shovel blade 8 to rotate synchronously, so that the front end of the shovel blade 8 fits the grip rod 1; thereby reducing the size of the device and greatly shortening the overall length after rotation. When the connecting rod 302 moves downward, it drives the limit block 311 fixedly connected thereto to move downward synchronously. The foot pedal 309, which loses the obstruction of the limit block 311, rotates around the hinge point with the connecting frame 7 under the force of the torsion spring 310, and finally makes the lower end of the foot pedal 309 fit the shovel blade 8, thereby reducing the size of the device. When the blade 8 needs to be used, the fixing nut 305 is rotated to rotate around the threaded shaft and move upward. When the fixing nut 305 moves upward, the connecting rod 302 is driven to move upward. When the connecting rod 302 moves upward, the short rod 307 fixedly connected thereto is driven to move upward synchronously. When the short rod 307 moves upward, the inner wall of the first connecting rod 308 is squeezed, so that one end of the first connecting rod 308 is subjected to an upward force and rotates around the other end. When the first connecting rod 308 rotates, the first rotating shaft 6 fixedly connected thereto is synchronously driven to move upward. When the first rotating shaft 6 rotates, it drives the connecting frame 7 fixedly connected thereto to rotate. When the connecting frame 7 rotates, it drives the shovel blade 8 to rotate synchronously, so that the front end of the shovel blade 8 is separated from the grip rod 1 and unfolded to enter a working state; when the connecting rod 302 moves upward, it drives the limit block 311 fixedly connected thereto to move upward synchronously, so that the limit block 311 squeezes the end arc surface of the foot pedal 309 to unfold, and finally the lower end of the foot pedal 309 is separated from the shovel blade 8 and enters a working state. The unfolding of the foot pedal 309 facilitates the workers to perform earth-moving operations.

[0030] See also Figure 1-Figure 6On the basis of the above embodiment, in another embodiment of the present invention, a mud removal device 4 for keeping the blade 8 clean is provided at the lower end of the grip 1, including a slide groove 401, a slider 402, a scraper block 403, a return spring 404, a fixed block 405, a second connecting rod 406, a semi-rotating tooth 407, a striking rod 408, a blocking sheet 409, a compression spring 410 and a protruding block 411.

The ends are fixedly connected. When the slider 402 slides in the slide groove 401, it drives the scraper block 403 to move synchronously. The outer side of the slider 402 is fixedly connected to one end of the return spring 404, and the other end of the return spring 404 is fixedly connected to the inner side of the fixed block 405. When the slider 402 loses other forces, the return spring 404 pushes the slider 402 to quickly return to its original position and drives the scraper block 403 to return to its original position. The front end of the slider 402 is rotatably connected to one end of the second connecting rod 406, and the other end of the second connecting rod 406 is rotatably connected to the rear end of the semi-rotating tooth 407. The connecting frame 7 is dynamically connected, and the center point of the semi-rotating tooth 407 is fixedly connected to the hinge of the connecting frame 7 and the foot pedal 309. When the foot pedal 309 rotates, the semi-rotating tooth 407 rotates, so that the second connecting rod 406 drags the slider 402 to move, and the slider 402 drives the scraper block 403 to move synchronously, so as to remove the large pieces of soil of the shovel blade 8; the inner wall of the connecting frame 7 is slidably connected to the outer wall of the striking rod 408, and the outer wall of the striking rod 408 is fixedly connected to the inner wall of the blocking plate 409, and the upper end of the blocking plate 409 is fixedly connected to one end of the compression spring 410, and the compression spring 410 is fixedly connected to the inner wall of the blocking plate 409. The other end of the compression spring 410 is fixedly connected to the lower end of the connecting frame 7. When the driving rod 408 moves upward, it is quickly reset under the pressure of the compression spring 410. The upper end of the driving rod 408 is fixedly connected to the lower end of the protruding block 411, and the outer wall of the protruding block 411 fits with the semi-rotating tooth 407. When the semi-rotating tooth 407 rotates, it squeezes the protruding block 411 to make the driving rod 408 move upward. At this time, under the action of the compression spring 410, the driving rod 408 moves downward rapidly and knocks the upper end of the shovel blade 8, accelerating the falling of soil on the shovel blade 8.

[0031] The lower end of the handle 1 is provided with a scraping device 5 for scraping off the dirt on the foot pedal 309, and the scraping device 5 includes a rotating rod 501, a third connecting rod 502, a first rotating rod 503, a transmission block 504, a scraping block 505, a hinge seat 506, a hinge rod 507, a movable seat 508 and a push plate 509. The front end of the semi-rotating tooth 407 is fixedly connected to the rear end of the rotating rod 501, the outer wall of the rotating rod 501 is rotatably connected to the inner wall of the third connecting rod 502, and the inner wall of the third connecting rod 502 is rotatably connected to the outer wall of the first rotating rod 503. When the semi-rotating tooth 407 rotates, the third connecting rod 502 squeezes the first rotating rod 50 3 movement, the rear end of the first rotating rod 503 is fixedly connected to the front end of the transmission block 504, and the rear end of the transmission block 504 slides on the front end of the foot pedal 309, the rear end of the transmission block 504 is fixedly connected to the front end of the scraping block 505, and the lower end of the scraping block 505 is fitted with the upper end of the foot pedal 309, the hinge seat 506 is slidably installed on the side wall of the scraper 8, one end of the hinge rod 507 is hinged on the hinge seat 506, and the other end of the hinge rod 507 is hinged to the bottom of the foot pedal 309, the moving seat 508 is fixed to the bottom of the hinge seat 506, and the push plate 509 is fixed to the bottom of the moving seat 508.

[0032] When the semi-rotating tooth 407 rotates, the rotating rod 501 at its front end moves synchronously, so that one end of the third connecting rod 502 is subjected to force and the other end of the third connecting rod 502 is squeezed. When the other end of the third connecting rod 502 is squeezed, the third connecting rod 502 pushes the first rotating rod 503 to move, which pushes the transmission block 504 to move and slide on the front end of the foot pedal 309, so that the scraping block 505 moves synchronously on the upper end of the foot pedal 309, removes the surface soil of the foot pedal 309, prevents a large amount of soil from adhering to the foot pedal 309, reduces the friction between the foot pedal 309 and the sole of the foot, reduces work efficiency, and makes it inconvenient for workers to step on the foot pedal 309 to shovel soil.

[0033] And when the foot pedal 309 is rotated and folded, through the cooperation of the hinged rod 507, the hinged seat 506, the movable seat 508 and the push plate 509, the relatively sticky soil attached to the bottom side wall of the shovel blade 8 can be pushed away and fall off the shovel blade 8, preventing the soil on the bottom side wall of the shovel blade 8 from being sticky and inconvenient to fall off, causing the shovel blade 8 to rust easily.

[0034] When the present embodiment is working: when the device is in working state, the fixing nut 305 is rotated downward, the pedal 309 rotates downward, and the half-rotating tooth 407 fixedly connected to the hinge of the connecting frame 7 and the pedal 309 rotates synchronously. When the half-rotating tooth 407 rotates, one end of the second connecting rod 406 moves synchronously. At this time, the other end of the second connecting rod 406 pulls the slider 402, so that the slider 402 squeezes the reset spring 404 to slide in the slide groove 401. When the slider 402 slides, it drives the scraper block 403 moves synchronously, so that it slides on the surface of the scraper 8, scrapes off the large pieces of dirt on the surface of the scraper 8, and keeps the scraper 8 clean; at the same time, when the semi-rotating tooth 407 rotates, the teeth of the semi-rotating tooth 407 squeeze the protruding block 411. When the protruding block 411 is squeezed upward, the striking rod 408 moves upward synchronously. When the striking rod 408 moves upward, it drives the blocking piece 409 to move upward synchronously. When the blocking piece 409 moves upward, it drives and squeezes the compression spring 410 so that the compression spring 410 is in In the compressed state, when the compression spring 410 is in the compressed state and the protruding block 411 passes over a tooth, the protruding block 411, which loses the upward squeezing force of the tooth, moves downward rapidly under the action of the compression spring 410, so that the lower end of the striking rod 408 quickly strikes the upper end of the shovel blade 8 until the protruding block 411 moves to the next tooth, and the above process is repeated, and the striking rod 408 strikes the upper end of the shovel blade 8 repeatedly, knocking off the small pieces of soil remaining on the shovel blade 8; on the contrary, when the device is in the folded state, the protruding block 411 loses the upward squeezing force of the tooth, and moves downward rapidly under the action of the compression spring 410, so that the lower end of the striking rod 408 quickly strikes the upper end of the shovel blade 8 until the protruding block 411 moves to the next tooth, and the above process is repeated, and the striking rod 408 strikes the upper end of the shovel blade 8 repeatedly, and knocks off the small pieces of soil remaining on the shovel blade 8; on the contrary, when the device is in the folded state, the protruding block 411 moves downward rapidly under the action of the compression spring 410, and ... strikes the upper end of the shovel blade 8 When in the state, the foot pedal 309 is free from obstruction and pops out. At this time, the half-rotating tooth 407 rotates. When the half-rotating tooth 407 rotates, one end of the second connecting rod 406 moves synchronously. At this time, the other end of the second connecting rod 406 pushes the slider 402. At the same time, one end of the reset spring 404 squeezes the fixed block 405, and the other end releases the pressure, so that the slider 402 squeezes the reset spring 404 and slides quickly in the slide groove 401 and resets. When the slider 402 slides, it drives the scraper block 403 to move synchronously, so that it resets quickly.

[0035] When the device is in working state, the half-rotating gear 407 rotates. When the half-rotating gear 407 rotates, the rotating rod 501 at its front end moves synchronously. When the rotating rod 501 moves, one end of the third connecting rod 502 is subjected to force and squeezes the other end of the third connecting rod 502. When the other end of the third connecting rod 502 is squeezed, the third connecting rod 502 pushes the first rotating rod 503 to move. When the first rotating rod 503 moves, it pushes the transmission block 504 to move and slide on the front end of the pedal 309. When the transmission block 504 moves, the scraping block 505 moves synchronously on the pedal. The upper end of the plate 309 removes the surface soil of the foot pedal 309 to prevent the wet soil from reducing the friction between the foot pedal 309 and the sole of the foot and reducing work efficiency. When the foot pedal 309 is rotated and stored, the foot pedal 309 rotates toward the shovel blade 8, which will cause the foot pedal 309 to squeeze the hinge rod 507, causing the hinge rod 507 to rotate at the hinge, so that the hinge rod 507 can squeeze the hinge seat 506 and the movable seat 508 to move downward, so that the movable seat 508 drives the push plate 509 to push away the sticky soil on the bottom side wall of the shovel blade 8.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
