Description

Technical Field

[0001] The utility model belongs to the field of garden management, and in particular relates to a garden branch and leaf pruning device. Background Technique

[0002] With the continuous advancement of urbanization construction, the construction of gardens and greening facilities has gradually matured. In the daily management of gardens, gardeners often need to use various types of garden tools. Among them, garden shears are commonly used tools for gardeners to prune branches and leaves of trees, so as to beautify the trees and facilitate the growth of trees. At present, when using the existing garden shears, the pruned branches and leaves directly fall to the ground. These branches and leaves need to be cleaned up by the gardener after pruning other plants. However, these branches and leaves fall on the ground in a messy manner, bringing greater labor intensity and cleaning difficulty to the gardener. At the same time, although the garden shears adopt the lever principle, a certain amount of force is still required when pruning branches and leaves. Therefore, when pruning a large area of gardens, the hands are prone to soreness. Content of the Utility Model

[0003] The purpose of the utility model is to provide a garden branch and leaf pruning device, which can reduce the labor intensity when pruning branches and leaves and the difficulty of cleaning branches and leaves.

[0004] The described garden branch and leaf pruning device includes a first handle and a second handle. The upper ends of the first handle and the second handle are hinged in a scissor shape by a rivet. Installation blocks are fixed at the tops of the first handle and the second handle. A shearing component for pruning branches and leaves and a clamping component for clamping the sheared branches and leaves are installed between the two installation blocks. An installation sleeve is sleeved at the hinge of the first handle and the second handle, and both the front and rear ends of the rivet are fixed on the inner wall of the installation sleeve. A driving mechanism for driving the first handle and the second handle to approach each other is installed on the installation sleeve.

[0005] Further, the shearing component includes a shearing knife and a fixed block. The shearing knife and the fixed block are respectively fixed on one of the installation blocks, and a receiving groove for the shearing knife to be embedded is formed at one end of the fixed block facing the shearing knife.

[0006] Further, the clamping component includes two clamping blocks. Installation grooves are formed on the opposite surfaces of the two installation blocks. One ends of the two clamping blocks are installed in one of the installation grooves through springs and are in left-right sliding fit therewith.

[0007] Further, fixing grooves are formed at one ends of the clamping blocks located in the corresponding installation grooves. One end of the spring is fixed at the bottom of the installation groove, and the other end is fixed at the bottom of the fixing groove.

[0008] Further, when the spring is in a natural state, the width of the clamping block is greater than the width of the fixed block and the shearing knife.

[0009] Furthermore, the driving mechanism includes a rotatable shaft that is installed within a mounting sleeve. A motor for driving the rotation of the shaft is installed on the front side wall of the mounting sleeve. Two pulling ropes are arranged within the mounting sleeve. One end of each of the two pulling ropes is fixed to the first handle and the second handle respectively, and the other ends of the two pulling ropes are both wound around the shaft.

[0010] Furthermore, at the ends of the first handle and the second handle located within the mounting sleeve, limiting rods are fixedly inserted. Limiting chutes for restricting the sliding direction of the limiting rods are formed on the inner wall of the mounting sleeve.

[0011] Furthermore, at the ends of the first handle and the second handle away from the hinge, grips that are slidably fitted therewith are sleeved. Bolts that are threadedly fitted therewith and used to fix the position after the grips slide are inserted through the grips.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] In the present utility model, the motor drives the rotation of the shaft, causing the two pulling ropes to wind around the shaft, thereby pulling the first handle and the second handle closer to each other. Then, the two mounting blocks are made to approach each other. Together with the shearing assembly and the clamping assembly, automatic shearing and clamping operations on the trimmed branches and leaves can be achieved, eliminating the need for manual shearing by the staff, thus reducing the labor intensity of the staff when shearing branches and leaves. Among them, the shearing assembly makes the first handle and the second handle approach each other, causing the shearing blade to be inserted into the receiving groove of the fixed block, thereby achieving the shearing of the branches and leaves. At the same time, this shearing method can effectively reduce the damage to the shearing blade caused by friction compared with the shearing method of scissors, improving the service life of the shearing blade. The clamping assembly can clamp the trimmed branches and leaves through two slidable clamping blocks, enabling the staff to place the trimmed branches and leaves together in one place, thus preventing the trimmed branches and leaves from falling messily to the ground, reducing the work intensity and difficulty of the staff in cleaning the trimmed branches and leaves. At the same time, the spring provides elastic force to ensure that the clamping blocks can fully clamp the trimmed branches and leaves. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following further illustrates the present utility model through specific embodiments in conjunction with the accompanying drawings, but it is not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present invention.

[0020] Embodiment 1

[0021] A garden branch and leaf pruning device described in this embodiment includes a first handle 1 and a second handle 9. The upper ends of the first handle 1 and the second handle 9 are hinged in a scissor shape by a rivet 4, as Figure 1 and Figure 4 shown. A through groove communicating left and right is opened at the upper end of the second handle 9. The upper end of the first handle 1 independently passes through this through groove, and through holes for the rivet 4 to pass through are opened at one end of the second handle 9 where the through groove is opened and at one end of the first handle 1 located in the through groove;

[0022] Refer to Figure 1 , Figure 3 and Figure 4 , installation blocks 5 are fixed to the tops of both the first handle 1 and the second handle 9. A shearing knife 8 and a fixed block 6 are provided between the two installation blocks 5. The shearing knife 8 and the fixed block 6 are respectively fixed to one of the installation blocks 5, and a receiving groove for the shearing knife 8 to be embedded is opened at one end of the fixed block 6 facing the shearing knife 8 (the shearing knife 8 and the fixed block 6 as a whole in this paragraph constitute the shearing assembly for pruning branches and leaves. In actual application, the fixed block 6 can also be a blade and be tangent to the shearing knife 8). In this embodiment, by bringing the first handle 1 and the second handle 9 closer to each other, the shearing knife 8 is clamped into the receiving groove of the fixed block 6, thereby realizing the shearing of branches and leaves. At the same time, this shearing method can effectively reduce the damage to the shearing knife 8 caused by friction compared with the shearing method of scissors, and improve the service life of the shearing knife 8; as Figure 1 , Figure 3 and Figure 4 shown, the fixed block 6 is integrally in a "U" - shaped structure, the fixed block 6 is fixed to the right side wall of the installation block 5 on the left, and the shearing knife 8 is fixed to the left side wall of the installation block 5 on the right;

[0023] Refer to Figure 1 , Figure 3 and Figure 4, there are two clamping blocks 7 between the two mounting blocks 5. Mounting grooves are provided on the opposite surfaces of the two mounting blocks 5. One end of each of the two clamping blocks 7 is installed in one of the mounting grooves through a spring 15 and is in left-right sliding fit therewith (the two clamping blocks 7 and the spring 15 in this paragraph together constitute the clamping assembly for clamping the pruned branches and leaves. In actual application, the spring 15 can also be an elastic metal sheet). In this embodiment, the two slidable clamping blocks 7 can clamp the pruned branches and leaves, enabling the staff to place the pruned branches and leaves together uniformly, thus preventing the pruned branches and leaves from falling messily on the ground, reducing the working intensity and difficulty for the staff to clean the pruned branches and leaves. At the same time, the spring 15 provides elastic force to ensure that the clamping blocks 7 can fully clamp the pruned branches and leaves; fixing grooves are provided at one end of each clamping block 7 located in the corresponding mounting groove. One end of the spring 15 is fixed to the bottom of the mounting groove, and the other end is fixed to the bottom of the fixing groove; the fixing block 6 and the cutting blade 8 are both located in front of the corresponding clamping block 7;

[0024] As Figure 1 , Figure 3 and Figure 4 shown, when the spring 15 is in its natural state, the width of the clamping block 7 is greater than the widths of the fixing block 6 and the cutting blade 8, so that the pruned branches and leaves can be in a clamped state before being cut, ensuring that the pruned branches and leaves can be in a clamped state after being cut;

[0025] An installation sleeve 3 is sleeved at the hinge joint of the first handle 1 and the second handle 9. The front and rear ends of the rivet 4 are fixed to the inner wall of the installation sleeve 3. As Figure 1 , Figure 2 and Figure 4 shown, the installation sleeve 3 can effectively limit the maximum opening angle of the first handle 1 and the second handle 9. The installation sleeve 3 is semicircular, with an open bottom end and a channel provided at the top;

[0026] Refer to Figure 1 , Figure 2 and Figure 4, a freely rotatable rotating shaft 10 is installed inside the installation sleeve 3. A motor 14 for driving the rotation of the rotating shaft 10 is installed on the front side wall of the installation sleeve 3. Two pulling ropes 11 are arranged inside the installation sleeve 3. One ends of the two pulling ropes 11 are respectively fixed to the first handle 1 and the second handle 9, and the other ends of the two pulling ropes 11 are both wound around the rotating shaft 10 (the rotating shaft 10, the motor 14 and the pulling ropes 11 in this paragraph together constitute the driving mechanism for driving the first handle 1 and the second handle 9 to approach each other. In actual application, the motor 14 can be a motor with a gear reducer or a DC reduction motor). In this embodiment, the motor 14 drives the rotation of the rotating shaft 10, so that the two pulling ropes 11 are wound around the rotating shaft 10, thereby pulling the first handle 1 and the second handle 9 to approach each other, and then making the two mounting blocks 5 approach each other. Then, in cooperation with the shearing assembly and the clamping assembly, the automatic shearing and clamping operations of the trimmed branches and leaves can be realized, without the need for the staff to manually shear the branches and leaves, thereby reducing the labor intensity of the staff when shearing the branches and leaves; as Figure 1 , Figure 2 and Figure 4 shown, one end of the rotating shaft 10 is installed on the inner wall of the installation sleeve 3, and the other end independently passes through the side wall of the installation sleeve 3 and is connected to the power output end of the motor 14. The housing of the motor 14 is fixed on the front side wall of the installation sleeve 3; among them, the motor 14 can be powered by a storage battery, and at the same time, the switch is arranged on the first handle 1 or the second handle 9;

[0027] As Figure 1 and Figure 2 shown, fixed limit rods 2 are installed through the ends of the first handle 1 and the second handle 9 located inside the installation sleeve 3, and limit sliding grooves for restricting the sliding direction of the limit rods 2 are opened on the inner wall of the installation sleeve 3.

[0028] When this embodiment is in use, hold a second handle 9 with one hand. When the trimmed branches and leaves are relatively small, the first handle 1 and the second handle 9 can be directly manually brought closer. During this process, the two clamping blocks 7 will first clamp the branches and leaves to be trimmed, and then the shearing knife 8 will shear the branches and leaves. After shearing, the whole moving device will then release the first handle 1 and the second handle 9 to uniformly place the trimmed branches and leaves. When the branches and leaves to be trimmed are relatively large, the switch on the first handle 1 or the second handle 9 is activated, and the motor 14 is started to reel in the two pulling ropes 11, so that the first handle 1 and the second handle 9 automatically approach each other, and then the larger branches and leaves are sheared.

[0029] Embodiment 2

[0030] In this embodiment, the technology will be further described. Sleeves 13 that are in sliding fit with them are sleeved on the ends of the first handle 1 and the second handle 9 far from the hinge. Bolts 12 that are in threaded fit with them and are used to fix the position of the sleeve 13 after sliding are installed on the sleeve 13. As Figure 1 and Figure 4As shown, in this embodiment, the overall lengths of the second handle 9 and the grip 13 can be adjusted by bolts 12 and a slidable grip 13, enabling the staff to adjust according to the size of the vegetation to be trimmed and improving the trimming range.
