Rolling wheel type variable-diameter branch human-assisted blueberry picking device

Abstract

The invention provides a rolling wheel type variable-diameter branch manual-assisted blueberry picking device. which comprises handles, a supporting rod, a spring, a picking device and a collection bag; the handles are fixedly provided with the spring, the supporting rod and the picking device; the supporting rod is installed on the handles and is hinged to the handles; the picking device is formed by rolling wheels, telescopic rods, springs and rotary cutters; the springs are pressure springs; one end of each telescopic rod is connected with the corresponding rolling wheel; the other end of each telescopic rod penetrates through the corresponding spring and a through hole formed in the corresponding handle and is connected with the corresponding handle; one end of a connecting rod is fixed to the corresponding telescopic rod through a bolt; the other end of each connecting rod is connected with the corresponding rotary cutter through a bolt; and a blade of each rotary cutter is in a trapezoid shape. When the rolling wheel type variable-diameter branch manual-assisted blueberry picking device is used, a long bottom edge of each trapezoid shape is close to the surface of a blueberry branch, a U-shaped groove is formed in the external circular surface of each rolling wheel, the handles are manually assisted, a power switch is started, the rolling wheels rotate on the blueberry branch, the rotary cutters cut a fruit stem of a blueberry, and the blueberry falls into the collection bag.

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 blueberry picking in our country adopts manual picking. There are four 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 a picking comb. 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 stalk by pulling. Squeeze ability, when the stalk is separated from the blueberry, part of the peel or pulp of the blueberry falls off, which leads to the loss of nutrients in the blueberry. This kind of destructive picking, the third method is the air-suction type, the airflow cannot enter between the clustered fruits, even if t...

Problems solved by technology

[0002] At present, most of the blueberries in our country are picked by hand. There are four ways. The first way is to pick directly from the blueberry branches by hand, and the picking efficiency is low. The second way 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 ability, 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, and the extrusion of the comb teeth on the surface of the blueberry will cause the skin to be damaged, the surface will oxidize, and affect the quality of the blueberry. A destructive picking method, the third method is the air suction type, the airflow cannot enter between the clustered fruits, even if the air flow increases, the air suction type cannot be picked at all, and the air suction type determines that the airflow type picking cannot be realized , the fourth way is clamping, the surface produces relative motion, 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 sentient animal. Blueberries have different growth years, and the tensile strength of their fruit stalks is not the same
