Roller type reducing branch artificial assistance blueberry picking device

Abstract

The invention provides a roller type reducing branch artificial assistance blueberry picking device which comprises a handle, a supporting rod, a spring, a picker and a collection bag. The spring, the supporting rod and the picker are fixedly installed on the handle. The supporting rod is installed on the handle and hinged to the handle. The picker is composed of a roller, a stretchable rod, a spring and a cutter. The spring is a compression spring, one end of the stretchable rod is in linkage with the roller, the other end of the stretchable rod penetrates through through holes formed in the spring and the handle and is in linkage with the handle, the cutter is in linkage with the stretchable rod through a bolt, the point of the cutter is in a U shape, the bolt is loosened, the cutter is rotated, an included angle formed between the cutter and the outer surface of a blueberry branch is 0-30 degrees, a U-shaped groove is formed in the external circle of the roller, force in the forward direction is exerted to the handle, the roller rotates on the blueberry branch, the cutter is driven to move, the cutter cuts off stems of blueberries, and the blueberries fall into the collection bag to be recycled.

Description

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

[0002] At present, most of the blueberries in our country are picked by hand. There are four picking methods. The first method is to pick directly from the blueberry branches by hand, which has low picking efficiency. The second method is to use picking combs. When picking, the blueberries are located between the two comb teeth of the picking comb, and the power drives the comb teeth to rotate, and the blueberries are separated from the fruit stem by pulling. Squeeze resistance. When the fruit stalk is separated from the blueberry, part of the skin or pulp of the blueberry will fall off, causing the loss of nutrients in the blueberry. The extrusion of the comb teeth on the surface of the blueberry will cause damage to the skin and oxidation of the surface, which will affect the quality of the blueberry. 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 clamping, the surface generates relative movement, and the surface of the blueberry is seriously damaged. The fifth way is to imitate the robot. The robot's fingers can't replace the human in any case, and the human is a high-level sensory Animals, the growth years of blueberries are different, the tensile strength of the fruit stalk is different, and the pulling force is also different
