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.
