Pickup device for walnuts with green husks

Abstract

The green walnut pickup device comprises a protective sleeve, a holding rod and a taking assembly, the protective sleeve is arranged at the lower end of the holding rod, the taking assembly is arranged in the protective sleeve, the taking assembly comprises a supporting body, a taking needle and a telescopic spring, radial mounting holes are evenly distributed in the supporting body, needle outlet holes are formed in the positions, right opposite to the mounting holes, of the protective sleeve, and the needle outlet holes are communicated with the supporting body. A sliding block is arranged at the inner end of the taking needle, a telescopic spring, the sliding block and the taking needle are sequentially arranged in the mounting hole from inside to outside, the outer end of the taking needle extends out of the needle outlet of the protecting sleeve, and when the taking needle pierces the peel of a green-peel walnut, the hardness of a kernel is larger than that of the peel, and when the taking needle touches the kernel, the kernel is taken out. The picking-up needle pushes the sliding block to extrude the telescopic spring to move inwards, the picking-up needle is prevented from puncturing kernels in the picking-up process, the supporting body can move up and down in the axial direction of the protective sleeve under the action of external force, the outer end of the picking-up needle swings, the green-husk walnuts are separated from the picking-up needle, and the green-husk walnuts falling to the ground can be picked up without bending down.

Description

technical field [0001] The invention relates to the technical field of forestry hand tools, in particular to a green walnut picker. Background technique [0002] There are usually two harvesting methods for green walnuts, one is manual picking, and the other is picking by knocking down. Because the efficiency of manual picking is low, the way of picking by knocking down is often used at present. The canopy of the tree is knocked down with a falling rod. When the walnut falls on the ground below, it is picked up manually by bending over. The long-term labor is not only labor-intensive, but also the walnut skin contains a large amount of walnut green skin, which sticks to the hands of the human body. After that, it will oxidize and turn black, damaging the skin of the hands. [0003] For this reason, research and develop a kind of easy to carry, easy to use, the instrument of fast collection green skin walnut is the problem that those skilled in the art need to solve urgently...
