Nut picking machine

Abstract

The invention discloses a nut picking machine. The nut picking machine comprises a tail machine box, a machine rod and a machine head, and the tail machine box is internally provided with a driving motor; the machine rod extends in the front-back direction and is hollow, at least one transmission shaft or a plurality of transmission shafts in end-to-end transmission connection are arranged in the machine rod, and an output shaft of the driving motor is in transmission connection with the closest transmission shaft; and the machine head comprises a machine head shell, a crank connecting rod mechanism located in the machine head shell and a picking head located in front of the machine head shell and used for hooking branches, a reciprocating motion rod extending in the front-back direction is arranged in the machine head shell, the reciprocating motion rod extends out of the front end of the machine head shell and is connected with the picking head, the transmission shafts penetrate into the machine head shell from the rear end of the machine head shell, and the crank connecting rod mechanism is in transmission connection with the transmission shafts and the reciprocating motion rod and used for converting rotation of the transmission shafts around the shaft into front-back linear reciprocating motion of the reciprocating motion rod. The nut picking machine has the beneficial effect that the transmission efficiency can be improved.

Description

technical field [0001] The invention relates to a nut picking machine, which is mainly used in the technical field of nut picking equipment. Background technique [0002] Nuts such as walnuts and chestnuts can be picked manually by tapping with bamboo poles, long sticks, etc., or using nut picking equipment. Large-scale picking equipment is often used abroad. The nuts on the branches are vibrated and picked by hitting or shaking the trunk, but this type of equipment is more troublesome to use, inconvenient to move, and the price is relatively high. Fruit trees are often located in hilly areas that are not suitable for large equipment, so small, hand-held nut pickers are often used. [0003] For example, the patent application whose publication number is CN204968562U discloses a novel nut picker, which includes an accelerator handle, a retractable transmission shaft, a power source, a flexible shaft, a beater, a beater, a first telescopic tube, a second Two telescopic tubes...

AI Technical Summary

Problems solved by technology

But this kind of nut picking machine still has the following problems: connecting rods, linear moving parts, push-pull rods, and first joint rods are arranged between the crank linkage mechanism and the picking head (push-pull mechanism), and the connecting rods and linear connecting parts are connected by pins , the linear connector and the push-pull rod are socketed, and the push-pull sleeve is set between the push-pull rod and the first segment rod; the total length of the connecting rod, the linear connector, the push-pull rod, and the first segment rod is relatively long. It is prone to bending and deformation, resulting in inaccurate positioning of the reciprocating movement of the picking head (push-pull mechanism), and it is prone to shaking and shaking, which will affect stability; in addition, the power mechanism will rotate around the axis and transmit it to the connecting rod through the crank linkage mechanism , due to the change of the power mode, the kinetic energy loss of the transmission to the connecting rod is relatively large. The structure is also prone to severe friction and even jamming, resulting in a large attenuation of kinetic energy from the final transmission to the picking head (push-pull mechanism). The above two points will affect the effect of the picking head hitting the branch

In addition, it is easy to operate the picking head (push-pull mechanism) to hook relatively horizontal branches, but it is more difficult to hook the branches that are inclined to the vertical, such as branches or branches that are closer to the trunk.
