Roller electromagnetic-push-and-pull size-changed manual-assisted electric branch mulberry picker

Abstract

The invention provides a roller electromagnetic-push-and-pull size-changed manual-assisted electric branch mulberry picker. The roller electromagnetic-push-and-pull size-changed manual-assisted electric branch mulberry picker comprises handles, a supporting rod, a spring, a picking device and a collecting bag, wherein the spring, the supporting rod and the picking device are fixedly mounted on the handles, the supporting rod is mounted on the handles and is hinged to the handles, the picking device consists of rollers, telescopic rods, springs and shear knives, the springs are compression springs, one end of each telescopic rod is connected with one corresponding roller, the other end of each telescopic rod penetrates through one corresponding spring and a through hole formed in one corresponding handle and is connected with the corresponding handle, one end of each connecting rod is fixed on one corresponding telescopic rod through a bolt, the other end of each connecting rod penetrates through an axial hole formed in one corresponding shear knife, cutting edges of the shear knives are serrate, and U-shaped grooves are formed in outer circle faces of the rollers; and the handles are manually assisted, a power switch is turned on, electromagnetic push-and-pull devices drive the shear knives to reciprocate, the rollers rotate on mulberry branches, fruit stems of mulberries are cut off by the shear knives, and the mulberries fall into the collecting bag.

Description

technical field [0001] The invention relates to a roller electromagnetic push-pull type variable-diameter branch artificially assisted electric mulberry picker, which belongs to the technical field of agricultural machinery. Background technique [0002] At present, most of the mulberries in our country are picked by hand, and there are six picking methods. The first method is to pick directly from the mulberry branches by hand, and the picking efficiency is low. The second method is to use picking combs. When picking, the mulberries are located between the two comb teeth of the picking comb, and the power drives the comb teeth to rotate, and the mulberries are separated from the fruit stem by pulling. Resistance to crushing. When the stalk is separated from the mulberry, part of the skin or pulp of the mulberry will fall off, causing the loss of nutrients in the mulberry. The extrusion of the comb teeth on the surface of the mulberry will cause damage to the skin and oxidat...

[0002] At present, most of the mulberries in our country are picked by hand, and there are six picking methods. The first method is to pick directly from the mulberry branches by hand, and the picking efficiency is low. The second method is to use picking combs. When picking, the mulberry is located between the two comb teeth of the picking comb, and the power drives the comb teeth to rotate, and the mulberry is separated from the fruit handle by pulling. Resistance to crushing. When the stalk is separated from the mulberry, part of the skin or pulp of the mulberry will fall off, causing the loss of nutrients in the mulberry. The extrusion of the comb teeth on the surface of the mulberry will cause damage to the skin and oxidation of the surface, which will affect the quality of the mulberry. One kind of destructive picking, the third method is the air-suction type, the airflow cannot enter between the clustered fruits, even if the air flow is increased, the air-suction type cannot be picked at all, the air-suction type determines that the airflow type cannot be picked Realization, the fourth way is the clamping type, the surface generates relative movement, which seriously damages the surface of the mulberry, the fifth way is the vibration and percussion type, during the falling process of the mulberry, the outer surface is damaged by gravity, and the sixth way Is the eccentric mass vibration picking
