Description

Technical Field

[0001] This utility model relates to the field of agricultural product harvesting technology, specifically a new type of harvesting shears. Background Technology

[0002] The harvester is equipped with harvesting blades at the head, which are used to cut the connection between the fruit stem and the branch, and then the stem is clamped and harvested.

[0003] A search revealed that the patent with patent number CN220897237U, entitled "Utility Model of Multifunctional Harvester," includes a support rod, a harvesting mechanism, and a handle. Research and analysis revealed that although the cooperation between the cutting blade and the gripping fingers during use enables cutting or gripping actions, thus expanding the harvester's application range and making its functions more comprehensive, it also has the following drawbacks to some extent.

[0004] For example, the lack of adjustment function makes it difficult to adjust the position of the clamp, resulting in difficulty in adapting to branches of different thicknesses. In actual operation, when faced with slender fruit branches and thick branches, the fixed-position clamp often cannot hold them accurately, and there is no auxiliary support structure. When using it with one hand, when encountering thicker branches or larger fruits that require greater force for picking, the pole is prone to shaking or even going out of control, which not only increases the difficulty of picking, but may also cause unnecessary damage to surrounding fruits, branches and leaves. In order to solve the above technical problems, we have designed a new type of picking shears. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of harvesting shears, which has the advantages of adjustment function and auxiliary support function. It solves the problem that existing harvesters cannot adjust the position of the clamp during use, resulting in the inability to clamp branches of different thicknesses and the inability to hold the stem stably.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel harvesting shear includes a pole body, a handle assembly riveted to the bottom of the pole body, a first pair of scissors riveted to the front side of the top of the pole body, a second pair of scissors movably connected to the right rear side of the first pair of scissors via bolts, a connecting rod fixedly connected to the left rear side of the second pair of scissors, a positioning plate riveted to the right front side of the second pair of scissors, an adjusting bolt threadedly connected to the right side of the positioning plate, a frame movably connected to the left side of the surface of the adjusting bolt via a pivot, a first clamping plate riveted to the left side of the frame, a second clamping plate bolted to the front side of the first pair of scissors, positioning bolts threadedly connected to the top and bottom of the right side of the positioning plate, and an auxiliary support mechanism fixedly sleeved on the bottom of the surface of the pole body, the auxiliary support mechanism including a rectangular sleeve.

[0007] Preferably, a bracket is riveted to the top left side of the rectangular sleeve, and a fastening bolt is movably connected through the front side of the bracket, with a handle movably sleeved on the surface of the fastening bolt.

[0008] Preferably, the left side of the first clamping plate is provided with an anti-slip groove, and the right side of the positioning bolt is riveted with a knob.

[0009] Preferably, a rubber block is riveted to the left end of the positioning bolt, and the left side of the rubber block is in contact with the first clamping plate.

[0010] Preferably, an arc-shaped hole is provided on the left side of the front side of the first scissors, and the front end of the connecting rod passes through the interior of the arc-shaped hole.

[0011] Preferably, a pull rod is movably connected to the top of the handle assembly via a pivot, and the top end of the pull rod passes through the rod body and is movably connected to the connecting rod via the pivot.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model has the advantage of adjustment function through the cooperation of positioning plate, adjusting bolt, frame, first clamping plate, second clamping plate and positioning bolt. Rotating the adjusting bolt can drive the first clamping plate to move left and right.

[0021] Please see Figures 1-5 A novel harvesting shear includes a pole 1, with a handle assembly 2 riveted to the bottom of the pole 1. A first pair of shears 3 is riveted to the front side of the top of the pole 1. A second pair of shears 4 is movably connected to the right rear side of the first pair of shears 3 via bolts. By setting the first pair of shears 3 and the second pair of shears 4, a cutting mechanism can be formed to cut branches. A connecting rod 5 is fixedly connected through the left rear side of the second pair of shears 4. A positioning plate 6 is riveted to the right front side of the second pair of shears 4. An adjusting bolt 7 is threaded through the right side of the positioning plate 6. By setting the adjusting bolt 7, the distance between the first clamping plate 9 and the second clamping plate 10 can be adjusted to accommodate branches of different thicknesses. The left side of the clamping and adjusting bolt 7 is movably connected to the frame 8 via a pivot. The left side of the frame 8 is riveted to the first clamping plate 9. The front side of the first shears 3 is connected to the second clamping plate 10 via bolts. The top and bottom of the right side of the positioning plate 6 are threaded with positioning bolts 11. By setting the positioning bolts 11, the positioning bolts 11 can drive the rubber block 18 to move. By the rubber block 18 pressing against or loosening the first clamping plate 9, the angle of the first clamping plate 9 can be finely adjusted, further improving the clamping accuracy of branches at different angles. The bottom of the surface of the pole 1 is fixedly fitted with an auxiliary support mechanism 12, which includes a rectangular sleeve 13.

[0022] Please see Figure 5 A bracket 14 is riveted to the top left side of the rectangular sleeve 13. A fastening bolt 15 is movably connected through the front side of the bracket 14. A handle 16 is movably fitted on the surface of the fastening bolt 15. By setting the handle 16, the handle 16 can be rotated 90 degrees, and the two hands can hold the handle assembly 2 and the handle 16 respectively, thus forming a two-hand support structure, reducing the sway of the rod 1. This is especially suitable for pruning thick branches or large fruits, improving operational stability.

[0023] Please see Figure 4The first clamping plate 9 has an anti-slip groove on its left side. By setting the anti-slip groove, the friction between the first clamping plate 9 and the branch can be increased. The concave and convex texture of the anti-slip groove can be embedded in the surface of the branch, especially the rough branch, thereby increasing the contact area and friction resistance, preventing the branch from sliding or falling off during clamping, and ensuring that it is not easy to slip when clamping the branch, thereby improving the stability and reliability of clamping. A knob 17 is riveted to the right side of the positioning bolt 11. By setting the knob 17, the positioning bolt 11 can be moved left and right by hand without additional tools, and the angle of the first clamping plate 9 can be quickly adjusted.

[0024] Please see Figure 4 A rubber block 18 is riveted to the left end of the positioning bolt 11. By setting the rubber block 18, when the rubber block 18 contacts the first clamping plate 9, its rough surface texture can increase the friction between the two, prevent the first clamping plate 9 from shifting due to force during the clamping of the branch, and ensure that the adjusted position remains stable. The left side of the rubber block 18 contacts the first clamping plate 9.

[0025] Please see Figure 2 An arc-shaped hole 19 is provided on the left side of the front side of the first scissors 3. By setting the arc-shaped hole 19, the design of the arc-shaped hole 19 makes the movement trajectory of the connecting rod 5 match the rotation trajectory of the scissors, ensuring that the force transmission is continuous and stable during the cutting process, improving the smoothness of operation and cutting efficiency. The front end of the connecting rod 5 extends through the interior of the arc-shaped hole 19.

[0026] Please see Figure 1 and Figure 2 The top of the handle assembly 2 is movably connected to the pull rod 20 via a pivot. The top of the pull rod 20 passes through the rod body 1 and is movably connected to the connecting rod 5 via the pivot.

[0027] When in use, during prolonged pruning and harvesting of branches, rotate the handle 16 90 degrees, then hold the handle assembly 2 with your right hand and the handle 16 with your left hand to improve the stability of the handle 1 and facilitate subsequent harvesting operations. During harvesting, squeeze the handle assembly 2, which moves the pull rod 20 downwards. The pull rod 20 moves the connecting rod 5 downwards, and the connecting rod 5 causes the second shears 4 to rotate. The second shears 4 works in conjunction with the first shears 3 to cut the branches. Simultaneously, the second shears 4 also moves the first clamping plate 9 during cutting. After the branch is cut, it is then... The first clamp 9 and the second clamp 10 are used to hold the branch. When the branch is thick, the adjusting bolt 7 can be rotated. The adjusting bolt 7 moves the first clamp 9 to the right, so the position of the first clamp 9 can be adjusted left and right. Rotating the top positioning bolt 11 clockwise moves the top positioning bolt 11 to the left, and rotating the bottom positioning bolt 11 counterclockwise moves the bottom positioning bolt 11 to the right. With the cooperation of the two positioning bolts 11, the angle of the first clamp 9 can be adjusted, thereby changing its position so that it can clamp branches of different thicknesses.

[0028] In summary, this new type of harvesting shear, through the cooperation of positioning plate 6, adjusting bolt 7, frame 8, first clamping plate 9, second clamping plate 10, positioning bolt 11, auxiliary support mechanism 12 and rectangular sleeve 13, solves the problem that existing harvesters cannot adjust the position of the clamps during use, resulting in the inability to clamp branches of different thicknesses and the inability to stably hold the stem.
