Description

Technical Field

[0001] The invention belongs to the technical field of gardening pruning, and in particular relates to a garden landscape pruning device. Background Art

[0002] Garden landscape pruning is an important means to maintain and enhance the beauty of the landscape. Regular pruning can not only control the growth form of plants and prevent overgrowth, but also help improve the disease resistance of plants and reduce the occurrence of diseases and insect pests. According to the needs of aesthetics, a spherical gardening pruning device was born;

[0003] It is mainly used to prune and shape various round shrubs, such as holly, boxwood, photinia, etc., to maintain their spherical appearance. The spherical gardening pruning device is mainly composed of three main parts: a supporting device, a transmission system and a cutting device. In the actual pruning process, since the pruning knife is pruned by a chain blade that continuously rotates in a circle, the farther the branches and leaves are from the center of the pruning tool, the greater the centrifugal force they are subjected to. During the continuous pruning process, they will be continuously thrown outward, and the leaves may be bounced back while splashing to other positions of the equipment. If they are stuck in the exposed mechanical structure or blade, it will cause the device to jam, and in severe cases, it will cause damage to parts. Summary of the invention

[0033] The trimming assembly 6 is fixedly mounted on the bottom of the adjusting assembly 5. The trimming assembly 6 includes an arc plate 61, which is fixedly connected to the output shaft of the second motor 54. The outer edge of the arc plate 61 is movably sleeved with a chain-type cutting knife 62. The right inner wall of the chain-type cutting knife 62 is movably clamped with a rotating wheel 65.

[0034] The third motor 63 rotates clockwise, and transmits the rotational force to the rotating wheel 65 through the bevel gear set 64, and then the rotating wheel 65 drives the chain-type cutting knife 62 to make a circular motion on the arc plate 61 to form a cutting effect, and then the second motor 54 is started to drive the guard plate 55 and the pruning assembly 6 to rotate slowly. One rotation cycle will approximately form a hemispherical shape, and the shrubs will be spherically pruned. When the leaves cut and thrown away by the chain-type cutting knife 62 reach the reamer 56, they will be cut again and thrown away from the guard plate 55 by the counterclockwise rotating reamer 56. When the moving block 51 moves left and right, the cleaning agent can also be sprayed on the cross bar 24 and the first screw rod 25 through the nozzle 53 to remove the splashed broken small leaves, which solves the problem that the leaves will be constantly thrown outward during the continuous pruning process.

[0040] The first motor 33 drives the large gear 32 to rotate clockwise, and the three small gears 34 rotate synchronously. The rings 36 on the tops of the three second screw rods 35 will drop accordingly, and the counterweight block 39 will be pushed downward through the connecting piece 37 and the bent rod 38. The conical counterweight block 39 will further lower the center of gravity to ensure the stability of the equipment during operation;

[0041] The fixing assembly 4 includes a round block 41, which is fixedly mounted on the bottom ends of the three second screw rods 35, and a cross cone 43 is fixedly mounted on the bottom of the round block 41. A guide block 42 is sleeved on the outer surface of the cross cone 43, and the guide block 42 is fixedly mounted on the outer side of the base 21.

[0042] The first motor 33 drives the large gear 32 to rotate clockwise, and the three small gears 34 rotate synchronously, driving the three second screw rods 35 to spirally descend, and the round block 41 will also descend, pushing the cross cone 43 downward along the guide block 42 into the soil to complete the fixation.

[0044] After the equipment is fixed, the auxiliary component 7 is installed as needed. If the branches at the bottom of the bush are scattered, the two semicircular blocks 71 can be moved to the bottom of the bush through the universal wheel 73, and the two semicircular blocks 71 can be merged through the quick-release ring 72. The merged semicircular blocks 71 form a complete ring, which has a gathering effect on the branches.

[0045] Working principle:

[0046] When using the present invention, firstly, the device is moved to the top of the shrubs to be pruned by two moving components 1, and the crawler 14 can rotate around the roller 13, so as to move smoothly on the soil, and the bearing 11 can drive the connecting rod 12 by rotating, so that the crawler 14 can be reversed;

[0047] When the equipment moves to the designated area, the counterweight assembly 3 is started first, the first motor 33 drives the large gear 32 to rotate clockwise, and the three small gears 34 rotate synchronously, driving the three second screw rods 35 to spirally descend, and the round block 41 will also follow the decline, pushing the cross cone 43 along the guide block 42 and inserting it into the soil to complete the fixation. When the counterweight assembly 3 is in operation, the ring 36 on the top of the three second screw rods 35 will also decline, and will push the counterweight block 39 downward through the connecting piece 37 and the bent rod 38. The conical counterweight block 39 will make the center of gravity further drop, ensuring the stability of the equipment during operation;

[0048] After the device is fixed, the auxiliary component 7 is installed as needed. If the branches at the bottom of the bush are scattered, the two semicircular blocks 71 can be moved to the bottom of the bush through the universal wheels 73, and the two semicircular blocks 71 can be merged through the quick release ring 72. The merged semicircular blocks 71 form a complete ring, which has a gathering effect on the branches.

[0049] After the preparations are completed, the third motor 63 is started first, and the third motor 63 rotates clockwise, and the rotation force is transmitted to the rotating wheel 65 through the bevel gear set 64, and then the rotating wheel 65 drives the chain-type cutting knife 62 to make a circular motion on the arc plate 61 to form a cutting effect, and then the second motor 54 is started to drive the guard plate 55 and the pruning assembly 6 to rotate slowly. A rotation cycle will approximately form a hemispherical shape, and the shrubs will be pruned in a spherical shape. When the leaves cut and thrown away by the chain-type cutting knife 62 reach the reamer 56, they will be cut again by the counterclockwise rotating reamer 56 and thrown away from the guard plate 55;

[0050] During circular pruning, the stroke of the hydraulic rod 22 can be retracted to drive the adjustment component 5 and the pruning component 6 close to the shrub. At the same time, the moving block 51 can also move laterally on the first screw rod 25 for further fine-tuning to ensure the roundness of the pruning. When the moving block 51 moves left and right, the cleaning agent can also be sprayed on the cross bar 24 and the first screw rod 25 through the nozzle 53 to remove the splashed broken leaves. The work process ends here.
