Description

Technical Field

[0001] The utility model relates to the technical field of forest and grass maintenance, in particular to a forest and grass maintenance device. Background Art

[0002] The application of forest and grass maintenance equipment plays a key role in forest and grass maintenance work. It aims to improve the efficiency and effectiveness of forest and grass maintenance through specific equipment and tools. Forest and grass maintenance mainly includes tree maintenance, lawn maintenance, inter-row cultivation and weeding, fertilization management, and cold protection and warmth preservation. Among them, lawn maintenance includes mowing management, watering management and drainage management.

[0003] The utility model patent with authorization announcement number CN219961364U discloses "A forest grass maintenance device for forestry". By turning on the power of the motor and the vacuum cleaner, the handrail is used to push the utility model to the position of the forest grass that needs to be harvested. The motor drives the first rotating shaft and the cutting knife to rotate at high speed. The broken grass falls to the ground under the obstruction of the gathering plate. The grass suction port sucks the broken grass when passing through the broken grass. The broken grass enters the filter bag after passing through the straw. After the grass harvesting is completed, the handle is pulled to open the movable door and the filter bag can be removed. By setting the gathering plate, the broken grass can be made to fall to the ground after hitting the gathering plate and will not splash everywhere, which makes it convenient for the grass suction port to suck the broken grass into the filter bag. No manual cleaning is required, and the collected broken grass can be processed into fertilizer.

[0004] However, the above-mentioned prior art solutions still have the following deficiencies: first, the length of the first rotating shaft is fixed, so that the distance between the cutting knife and the ground is also fixed, which results in that the height of the mowed lawn is unchanged and the harvesting height cannot be adjusted as needed; second, the cutting knife is fixedly connected to the first rotating shaft, which makes it difficult to disassemble and replace the cutting knife, and may become blunt after long-term use, thereby reducing the mowing efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a forest grass maintenance device that can adjust the mowing height, facilitate the disassembly and replacement of the cutting blade, and ensure the mowing efficiency.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A forest grass maintenance device comprises a box body, an adjustment mechanism is arranged on the box body, and a disassembly mechanism is arranged on the adjustment mechanism;

[0008] The adjusting mechanism comprises a servo motor, the output shaft of the servo motor is fixedly connected to a threaded rod, the outer side of the threaded rod is threadedly connected to a threaded plate, the top of the threaded plate is fixedly connected to a cutting motor, the output shaft of the cutting motor is fixedly connected to a rotating rod, a mounting groove is provided inside the rotating rod, a spring is fixedly connected to the outer side of the rotating rod, a stopper extending into the mounting groove is fixedly connected to one side of the spring, and a magnetic ring is fixedly connected to the bottom of the rotating rod;

[0009] The disassembly and assembly mechanism comprises a magnetic block, the top of the magnetic block is fixedly connected with a clamping block, and the bottom of the magnetic block is fixedly connected with a cutting knife.

[0010] Preferably, a handle is fixedly connected to the rear side of the box body, two supporting legs symmetrically distributed front to back are fixedly connected to the left and right sides of the bottom of the box body, and moving wheels are rotatably connected inside the supporting legs.

[0011] Preferably, the servo motor is fixedly connected to the top of the box, the output shaft of the servo motor extends to the inside of the box and is fixedly connected to the threaded rod, and the bottom of the threaded rod is rotatably connected to the inner bottom wall of the box.

[0012] Preferably, the four sides of the threaded plate are fixedly connected to limit blocks, and the inner walls of the four sides of the box body are provided with limit grooves that are compatible with the moving tracks of the limit blocks.

[0013] The limit block and the limit groove jointly limit the moving direction and moving distance of the threaded plate, thereby preventing the threaded plate from rotating together with the threaded rod.

[0014] Preferably, a through hole is provided at the bottom of the box body, the size of the through hole is larger than the size of the cutting knife, and the maximum distance that the threaded plate moves downward outside the threaded rod is smaller than the height of the supporting leg.

[0015] The distance that the threaded plate moves on the threaded rod is the adjustable range of the cutting knife height. Since the height of the supporting leg is greater than the adjustable range of the cutting knife height, the moving wheel at the bottom of the supporting leg can always contact the ground, avoiding damage to the cutting knife caused by contact with the ground.

[0016] Preferably, the number of the stoppers is two and they are symmetrically distributed left and right, and the opposite sides of the two stoppers are fixedly connected with a pressure block, and the pressure block is fixedly connected to the spring.

[0017] Preferably, the opposite sides of the two stoppers are both designed as inclined surfaces, the left and right sides of the clamping block are both designed as inclined surfaces, and a through hole matching the clamping block is provided inside the magnetic attraction ring.

[0018] Since the sides of the stopper and the card block are both designed with inclined surfaces, the card block can push the two stoppers to both sides during the upward movement, stretching the spring to continuously push the card block onto the stopper, and under the elastic force of the spring, the stopper rebounds to fix the position of the card block, thereby realizing the installation of the cutting knife.

[0019] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0020] First, by pushing the handle, the entire device can be moved under the action of the moving wheel, and the servo motor is started to drive the threaded rod to rotate. Under the restriction of the limit block and the limit groove, the threaded plate moves up and down to adjust the height of the cutting motor and the rotating rod fixedly connected thereto, so as to realize the adjustment of the mowing height.

[0021] Second, insert the card block on the cutting knife into the installation slot, push the two blocks outward, stretch the spring until the card block moves above the two blocks, and the block is reset under the elastic force of the spring, which can lock the position of the card block and fix the cutting knife on the rotating rod. At the same time, the magnetic block and the magnetic ring are magnetically attracted to further improve the fixing effect. When the cutting knife needs to be disassembled, pull the two blocks toward each other to remove the card block from the installation slot, completing the disassembly of the cutting knife, which is convenient for disassembly and replacement of the cutting knife to ensure mowing efficiency.

[0030] The adjusting mechanism 2 includes a servo motor 21, the output shaft of the servo motor 21 is fixedly connected to a threaded rod 22, the outer side of the threaded rod 22 is threadedly connected to a threaded plate 23, the top of the threaded plate 23 is fixedly connected to a cutting motor 24, the output shaft of the cutting motor 24 is fixedly connected to a rotating rod 25, the interior of the rotating rod 25 is provided with a mounting groove 26, the outer side of the rotating rod 25 is fixedly connected to a spring 27, one side of the spring 27 is fixedly connected to a stopper 28 extending into the mounting groove 26, and the bottom of the rotating rod 25 is fixedly connected to a magnetic ring 29;

[0031] The disassembly and assembly mechanism 3 comprises a magnetic block 31 , a clamping block 32 is fixedly connected to the top of the magnetic block 31 , and a cutting knife 33 is fixedly connected to the bottom of the magnetic block 31 .

[0032] Specifically, a handle is fixedly connected to the rear side of the box body 1, and two support legs 11 symmetrically distributed front to back are fixedly connected to the left and right sides of the bottom of the box body 1, and moving wheels 12 are rotatably connected inside the support legs 11.

[0033] Through the above technical solution, the handle is convenient for the operator to push the entire device, the support legs 11 can support the entire device, and the entire device can be driven to move through the moving wheels 12, thereby reducing the labor of manual handling.

[0034] Specifically, the servo motor 21 is fixedly connected to the top of the box body 1 , the output shaft of the servo motor 21 extends into the interior of the box body 1 and is fixedly connected to the threaded rod 22 , and the bottom of the threaded rod 22 is rotatably connected to the inner bottom wall of the box body 1 .

[0035] Through the above technical solution, the output shaft of the servo motor 21 is fixedly connected to the threaded rod 22 , and the threaded rod 22 can be driven to rotate in the box body 1 by the servo motor 21 .

[0036] Specifically, the four sides of the threaded plate 23 are fixedly connected to the limiting blocks 231 , and the inner walls of the four sides of the box body 1 are provided with limiting grooves 232 that are compatible with the moving tracks of the limiting blocks 231 .

Under the elastic force of the spring 27, the block 28 rebounds, fixing the position of the clamping block 32, and realizing the installation of the cutting knife 33, which is convenient for disassembly and replacement of the cutting knife 33 to ensure the mowing efficiency.
