Simple and practical Chinese chestnut pickup device

Abstract

The invention discloses a simple and practical Chinese chestnut pickup device. A pressing device comprises a threaded rod and a pressing part, the threaded rod is inserted into a small round tube, a sleeve is arranged at the lower end of the small round tube, a left square hole and a right square hole of symmetry are formed in the thick wall part of the upper left part and the thick wall part of the upper right part of the sleeve respectively in the axial direction, a through long strip is arranged in the left square hole and the right square hole, and the left end and the right end of the long strip are fixed to the upper end of a big round tube; an upper round baffle is arranged in the portion, below the long strip, of the sleeve, the long strip and the upper round baffle are connected with a thread on the lower portion of the threaded rod through a first threaded hole and a second threaded hole in the middle respectively in a matched mode, and a compression spring is arranged below the upper round baffle. The pickup device comprises a lower round baffle, an internal thread is arranged on the portion, below the lower round baffle, of the sleeve, and a cylindrical foam plate is arranged in the position, below the lower round baffle, of the sleeve. The simple and practical Chinese chestnut pickup device can pick up Chinese chestnuts easily and conveniently, obviously improves the operation efficiency and can avoid that spines growing densely on involucres stab the fingers.

Description

technical field [0001] The invention relates to the technical field of agricultural implements, in particular to a simple and practical chestnut picker. Background technique [0002] The nuts of the chestnut are hidden in the densely spiky involucre. Chestnuts fall to the ground when they are ripe, and people have to bend down to pick them up. Not only is the labor intensity extremely high, but the work efficiency is low, and the dense spikes on the involucre can even hurt fingers. Contents of the invention [0003] The object of the present invention is to provide a chestnut picker, which is not only convenient for picking up chestnuts easily, obviously improves the work efficiency, but also avoids the sharp thorns densely grown on the involucre from pricking fingers. [0004] The technical solution of the present invention is to design and manufacture a simple and practical chestnut picker including a pressing device, a picking device and a handle, the pressing device i...
