Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of walnut planting, in particular to a pruning machine for walnut planting. Background Art
[0002] Walnut, also known as walnut, belongs to the Juglandaceae family. Its varieties are divided into wild walnuts and artificially grafted improved varieties of walnuts. Originated in Central Asia, it is planted all over China. Generally, artificially improved varieties are chosen for planting. Walnut trees can be used as protective forests for road greening; because of its tough and elastic wood, it is also a top-grade material used in industry; walnut shells can be processed into works of art. Walnuts, almonds, cashews, and hazelnuts are collectively known as the "four major nuts" in the international market. For some dense branches that affect the growth of mother branches and block other ordinary branches from receiving light and nutrients, pruning is generally performed once every 2 to 3 years. Current pruning machines can usually only cut thinner branches. When cutting thicker branches, it is more laborious and difficult to cut, thereby reducing the efficiency of pruning. Utility Model Content

[0015] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate the understanding of technicians.
[0016] like Figure 1-4As shown, the utility model provides a pruning machine for walnut planting, comprising a support rod 1, a shearing mechanism 2, and a cutting mechanism 3; the shearing mechanism 2 is installed at the front end of the support rod 1, and the cutting mechanism 3 is installed on the support rod 1; the shearing mechanism 2 comprises a fixed blade 21, a movable blade 22, a connecting wire 23, and a driving mechanism 24; the fixed blade 21 is fixedly installed at the front end of the support rod 1, the middle part of the movable blade 22 is hinged at the front end of the support rod 1 to shear with the fixed blade 21, one end of the connecting wire 23 is hinged at the tail end of the movable blade 22, and the other end is hinged to the driving mechanism 24 installed on the support rod 1. When shearing thinner walnut branches, the support rod 1 is operated to make the branches to be pruned stuck between the fixed blade 21 and the movable blade 22, and then the driving mechanism 24 is operated to pull the connecting wire 23, so that the connecting wire 23 pulls the movable blade 22 to rotate, thereby cutting the branches. When the branches are thicker, the branches can be clamped and fixed by the shearing mechanism 2, and then the branches are cut by the cutting mechanism 3. The utility model can both shear and cut branches through the shearing mechanism 2 and the cutting mechanism 3. When the branches are thin, the shearing mechanism 2 can be used to shear and quickly shorten the branches. When the branches are thick and the shearing mechanism 2 is difficult to cut short, the cutting mechanism 3 can conveniently and labor-savingly cut the branches. Therefore, the utility model can quickly shear both thick and thin branches, thereby improving the pruning efficiency. The connecting wire 23 provided on the shearing mechanism 2 can be pulled as well as pushed, so as to conveniently control the opening and closing of the movable blade 22, thereby facilitating the shearing of branches.
[0017] The driving mechanism 24 includes a fixed handle 241 and a movable handle 242. The fixed handle 241 is fixedly mounted on the support rod 1, and the movable handle 242 is slidably mounted in a slide groove 243 provided on the support rod 1. The connecting wire 23 is hinged on the movable handle 242. The fixed handle 241 and the movable handle 242 are pinched to move the movable handle 242 in the slide groove 243, and the connecting wire 23 is pulled to pull the movable blade 22 to rotate and cut the branches. The movable handle 242 is pushed to push the movable blade 22 to open through the connecting wire 23, so that the branches are conveniently clamped between the fixed blade 21 and the movable blade 22 for cutting, thereby improving the cutting efficiency of the branches.
[0018] A return spring 244 is provided in the slide groove 243. When the movable handle 242 is pulled to cut the branches, the return spring 244 can automatically push the movable handle 242 back to its original position, thereby pushing the movable blade 22 to open through the connecting wire 23, so as to facilitate the next shearing.
[0019] The cutting mechanism 3 includes a circular blade 31, an L-shaped mounting frame 32, a screw rod 33, and a motor 34. The circular blade 31 is rotatably mounted on the L-shaped mounting frame 32, and the L-shaped mounting frame 32 is slidably mounted on the support rod 1. Both ends of the screw rod 33 are rotatably mounted on the fixed blocks 35 fixedly arranged on the support rod 1 through bearings. The screw rod 33 is threadedly connected to the L-shaped mounting frame 32, and the motor 34 is installed on the L-shaped mounting frame 32 and is transmission-connected to the circular blade 31. When the shearing mechanism 2 is difficult to cut thicker branches, the branches are clamped and fixed by the shearing mechanism 2, and then the screw rod 33 is rotated. Since the screw rod 33 is threadedly connected to the L-shaped mounting frame 32, the L-shaped mounting frame 32 is driven to move on the support rod 1, and the motor 34 drives the circular blade 31 to rotate, thereby cutting the branches, thereby improving the efficiency of cutting thicker branches.
[0020] The tail end of the screw rod 33 is connected to a rotating handle 36 for rotating the screw rod 33 through a gear transmission. The rotating handle 36 is connected by a gear, so that the rotating handle 36 can be kept at a certain distance from the support rod 1, which is convenient for rotating the rotating handle 36, thereby rotating the screw rod 33.
[0021] Working process:
[0022] When shearing thinner walnut branches, operate the support rod 1 to make the branches to be sheared be stuck between the fixed blade 21 and the movable blade 22, then pinch the fixed handle 241 and the movable handle 242 to make the movable handle 242 move in the slide groove 243, pull the connecting wire 23, thereby pulling the movable blade 22 to rotate to shear the branches, and the reset spring 244 can automatically push the movable blade 22 to open. When the branches are thicker, the branches can be clamped and fixed by the shearing mechanism 2, and then the screw rod 33 is rotated to drive the L-shaped mounting frame 32 to move on the support rod 1, and the motor 34 drives the circular blade 31 to rotate, thereby cutting the branches, thereby improving the efficiency of cutting the branches.
[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
