[0019] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. The described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0021] Figure 1-6 The invention comprises a pedal mechanism 1, a lateral top cover plate 1A, a pedal board 1B, a pedal limit plate 1C, a lateral outer sealing plate 1D, a pedal connecting rod 1E, a return spring 1F, a lateral bottom sealing plate 1G, a pedal lever 1H, a pedal lever support rod 1J, a lever gear driving end 1K, a one-way driving mechanism 2, a driving gear 2A, a driving disk 2B, a driving device rotating shaft 2C, a gear switching plate 2D, a check plate assembly 2E, a page turning shaft 2E-1, Rectangular opening 2E-2, rectangular patch 2E-3, spring fixing piece 2E-4, page turning fixing piece 2E-5, spring 2E-6, driving gear disc 2F, short driving gear 2G, long driving gear 2H, driving gear disc fixing shaft 2J, shearing mechanism 3, lateral outer sealing plate 3A, top cover plate 3B, cutter fixing shaft 3C, cutter 3D, root entry 3E, gear meshing mouth 3F, spring fixing column 3G, cutter return spring 3H, etc.

[0022] like Figure 1-6 As shown, the present invention is a shearing type shallow tree pool root growth prevention device, including a shearing mechanism 3, wherein the shearing mechanism 3 includes a shearing frame, a cutter 3D is hinged at one end of the shearing frame, the cutter 3D extends to the other end of the shearing frame, and a one-way driving mechanism 2 and a pedaling mechanism 1 are installed at the other end of the shearing frame.

[0023] The driving sprocket 2F of the unidirectional driving mechanism 2 is driven by the pedal mechanism 1 to realize unidirectional operation. Two groups of long driving gears 2H are symmetrically arranged on the circumferential surface of the driving sprocket 2F, and a group of short driving gears 2G are respectively arranged on the circumferential surface between the two groups of long driving gears 2H.

[0024] During the rotation of the driving toothed disc 2F, the long driving gear 2H can mesh with the gear meshing opening 3F constructed at the end of the cutter 3D, thereby driving the cutter 3D to rotate. An elastic reset component is arranged on the shearing frame. The long driving gear 2H drives the cutter 3D to rotate and squeezes the elastic reset component. When the driving toothed disc 2F rotates past the long driving gear 2H, the short driving gear 2G is disengaged from the gear meshing opening 3F. The elastic reset component drives the cutter 3D to rotate in the opposite direction to cut off the shallow roots extending into the root entry opening 3E. Multiple root entry openings 3E are arranged on the shearing frame.

[0025] like Figure 4 As shown, the shearing frame includes an outer sealing plate 3A and a top cover plate 3B, and a cutter 3D is rotatably arranged on the shearing frame via a cutter fixing shaft 3C.

[0026] The lower end of the head of the cutter 3D is rotatably connected to the cutter fixing shaft 3C.

[0027] The elastic reset assembly comprises a spring fixing column 3G and a cutter return spring 3H. The spring fixing column 3G is fixed to the top cover plate 3B. One end of the cutter return spring 3H is connected to the spring fixing column 3G, and the other end is connected to the cutter 3D.

[0028] like Figure 3 As shown, the one-way drive mechanism 2 also includes a driving gear 2A, a driving disc 2B, a rotating shaft 2C, a gear switching plate 2D, a check plate assembly 2E, and a driving gear disc fixing shaft 2J.

[0029] The driving gear 2A and the driving disc 2B are both fixed to the rotating shaft 2C, and the rotating shaft 2C is rotatably arranged on the lateral bottom side sealing plate 1G of the pedal mechanism 1. The driving disc 2B includes two disc bodies arranged parallel to each other, and the two driving discs 2B are connected by a spiral gear switching plate 2D. The driving gear 2A is located below the two driving discs 2B, and the check plate assembly 2E realizes the unidirectional rotation of the driving toothed disc 2F. In specific production practice, the driving gear 2A is in the shape of a right triangle.

[0030] like Figure 5 , 6As shown, the non-return piece assembly 2E is fixed on the lateral outer sealing plate 1D, and the non-return piece assembly 2E includes a non-return piece body, which is fixed on the lateral outer sealing plate 1D by a long strip fixing piece, and a rectangular opening 2E-2 is set at one end of the non-return piece body in the length direction, and the page turning shaft 2E-1 is installed on the non-return piece body through the page turning fixing piece 2E-5, and the rectangular patch 2E-3 is rotatably set on the page turning shaft 2E-1, and the rectangular patch 2E-3 can completely cover the rectangular opening 2 E-2, that is, the rectangular patch 2E-3 is larger than the rectangular opening 2E-2, and the rectangular patch 2E-3 is provided with a spring fixing piece 2E-4, and the page turning shaft 2E-1 is also provided with a spring 2E-6, one end of the spring 2E-6 is fixed to the spring fixing piece 2E-4, and the other end is clamped on the non-return plate body. Under the action of the spring, the rectangular patch 2E-3 is always in contact with the non-return plate body, and the driving gear 2A is also in contact after it rotates, and the driving gear 2A is prevented from rotating back. Figure 5 , 6 As shown, during operation, when the driving gear 2A rotates, through the rectangular opening 2E-2, under the action of the rectangular patch 2E-3, the driving gear 2A cannot rotate back and can only rotate in the clockwise direction.

[0031] like Figure 2 As shown, the pedal mechanism 1 includes a lateral top cover plate 1A, a pedal plate 1B, a pedal limit plate 1C, a lateral outer side sealing plate 1D, and a lateral bottom side sealing plate 1G. The upper end of the lateral outer side sealing plate 1D is fixed to the lateral top cover plate 1A, and the lower end is fixed to the lateral bottom side sealing plate 1G. The pedal plate 1B is arranged at the outer end of the lateral top cover plate 1A. The bottom surface of the lateral top cover plate 1A is vertically fixedly connected to the pedal connecting rod 1E. The pedal return spring 1F is installed on the lateral bottom side sealing plate 1G. The pedal link 1E cooperates with the pedal return spring 1F, and the lower end of the pedal link 1E is fixedly connected to the pedal lever 1H. The pedal lever 1H can rotate around the pedal lever support rod 1J. The pedal lever support rod 1J is vertically installed on the inner wall of the lateral outer sealing plate 1D. The inner end of the pedal lever 1H is the lever gear driving end 1K. The lever gear driving end 1K is arranged at the upper end of the pedal lever 1H and is triangular in shape to cooperate with the driving gear 2A of the one-way driving mechanism 2.

[0032] A pedal limit plate 1C is also fixedly arranged on the lateral outer sealing plate 1D, and the pedal limit plate 1C is used to limit the pedal board 1B.

[0033] When the present invention is working, the root needs to be cut to the depth of the tree root, and the corresponding model of the device or combination is selected for use; after stepping on the pedal mechanism 1, the pedal link 1E moves downward to compress the return spring 1F, and the pedal link 1E drives the pedal lever 1H to rotate, and the pedal lever 1H rotates with the pedal lever support rod 1J as the rotation fulcrum, and the lever gear driving end 1K at the inner end of the pedal lever 1H in a triangular shape drives the driving gear 2A to rotate, thereby driving the one-way driving mechanism 2 to operate. Figure 2 As shown, it can be understood that among the teeth uniformly distributed on the circumferential surface of the driving gear 2A, the shape of each tooth is a right triangle, and the right triangle driving portion of the lever gear driving end 1K cooperates with the right triangle shaped tooth profile of the driving gear 2A, so that the driving gear 2A rotates. Under the action of the check plate assembly 2E, the driving gear 2A cannot rotate and can only rotate in the clockwise direction. When the gear switching plate 2D rotates to the short driving gear 2G or the long driving gear 2H, it drives the driving sprocket 2F to rotate.

[0034] After the driving toothed disc 2F rotates, it drives the cutter 3D with a gear meshing opening to move upward. After continuing to rotate, when the short driving gear 2G rotates to a position flush with the gear meshing opening, it cannot mesh. Under the action of the cutter return spring 3H, the cutter 3D is pushed out to cut off the shallow roots extending into the root entry 3E. Since the circumferential surface of the driving toothed disc 2F is sequentially provided with short driving gears 2G and long driving gears 2H, the cutter 3D can be rotated around the cutter fixed shaft 3C, thereby achieving the cutting operation. During the stepping process of the pedal 1B, the pedal limit plate 1C is used to limit the pedal, and after the pedal link 1E is stepped on, the pedal return spring 1F is used to reset the pedal after being stepped on.

[0035] The invention is simple to use, and the corresponding model of device or combination is selected according to the depth of the tree root. After the pedestrian steps on it, a series of mechanical transmissions are used to finally cut the tree root. The invention is not only compact in structure and easy to use, but also can effectively control the growth of tree roots and protect structures such as sidewalks from damage, and has a wide range of application prospects.

[0036] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
