Description

Technical Field

[0001] The utility model relates to the technical field of agricultural tools, in particular to a novel fruit picker. Background Art

[0002] In fruit production, pears, citrus, loquats and other fruits need to be picked with a sharp tool to cut the fruit stem to ensure that the fruit is intact. When picking, one hand is required to grasp the fruit and the other hand to cut the fruit stem before placing it in a container. The two hands operate simultaneously, which is inefficient. The hands directly contact the surface of the fruit, which easily leaves fingerprints and affects the appearance of the fruit. This is especially true for fruits with soft flesh such as Baisha loquat. Once the fuzz on the fruit surface is damaged, the storage resistance is reduced in the later stage, the fruit loss is high, and the economic benefits are damaged. It is very necessary to develop a simple, efficient, one-handed operation tool that reduces the damage to the fruit surface during picking and reduces the loss of fruit picking. In response to the above situation, technical innovation is carried out on the basis of existing fruit picking. Utility Model Content

[0003] The purpose of the present invention is to provide a novel fruit picker to solve the problems raised in the above background technology.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] In the present invention, since the elastic force of the second torsion spring is greater than the elastic force of the first torsion spring, when the first clamping arm and the pruning arm are gripped, the first clamping arm and the first clamping block, as well as the second clamping arm and the second clamping block, will first clamp the fruit stem. Then, when the first clamping arm and the pruning arm are gripped, the sharpened portion of the pruning arm will be driven to cut the fruit stem. The grooves between the top of the second clamping arm and the second clamping block, and between the top of the first clamping arm and the first clamping block, allow the scissors to fit into the fruit stem without slipping, thereby achieving the effect of cutting the fruit stem from the branch without the fruit falling, greatly improving the efficiency of picking and reducing the loss rate of commercial fruit during the picking process. Actual measurements of citrus picking have shown that the present invention can achieve one-handed fruit picking, increasing the picking height of fruit at the top of the fruit tree by approximately 15-20 cm. At the same time, due to the convenience of one-handed operation, the efficiency of picking fruit at the top of the fruit tree is effectively improved, with an increase of 26.92%.

A first bolt 34 is rotatably provided in the third through hole, and the first bolt 34 passes through the third through hole and is screwed with a third nut 35. A second bolt 36 is rotatably provided in the fourth through hole, and the second bolt 36 passes through the fourth through hole and is screwed with a fourth nut 37. The left and right ends of the second torsion spring 14 are respectively wound around the outside of the first bolt 34 and the second bolt 36.

[0020] Working principle: Hold the first clamping arm 1 and the pruning arm 12 with your hand, and place the fruit stem between the first clamping arm 1 and the first clamping block 2 and the second clamping arm 11 and the second clamping block 21. At this time, hold the first clamping arm 1 and the pruning arm 12 inward. Since the elastic force of the second torsion spring 14 is greater than the elastic force of the first torsion spring 13, the first clamping arm 1 and the second clamping arm 11 will merge inward with the second screw 32 as the center point, thereby merging the first clamping arm 1 and the first clamping block 2 and the second clamping arm 11 and the second clamping block 21 to clamp the fruit stem. At this time, continue to hold the first clamping arm 1 and the pruning arm 1 2 causes the second torsion spring 14 to be deformed by the force, thereby causing the pruning arm 12 to flip around the first screw 3 as the center point, and then causing the sharp edge of the pruning arm 12 to slide in front of the first clamping block 2, thereby cutting off the fruit stalk. At this time, the cut fruit stalk is still clamped and fixed by the first clamping arm 1 and the first clamping block 2 as well as the second clamping arm 11 and the second clamping block 21, and the grooves between the top of the second clamping arm 11 and the second clamping block 2 and between the top of the first clamping arm 1 and the first clamping block 2 can enable the scissors to be embedded in the fruit stalk without slipping, thereby achieving the effect of cutting the fruit stalk from the branch without the fruit falling.
