Description

Technical Field

[0001] The utility model relates to the technical field of lotus pod harvesting, in particular to a lotus pod harvesting device. Background Technique

[0002] A lotus pod is the inverted conical spongy receptacle of the pistil of a lotus flower. There are dozens of holes in the receptacle connected like a honeycomb, forming a disc shape on the surface. Each hole contains 1 small nut, which is the lotus seed. After maturity, the whole lotus pod needs to be picked. It can be eaten fresh or processed into dried lotus seeds. Fresh lotus seeds are a delicious and healthy summer fruit, and dried lotus seeds are Chinese medicinal materials with high medicinal value.

[0003] At present, the main way to harvest lotus pods is still manual harvesting. Workers put on waterproof clothes and enter the lotus pond (field). After judging the lotus pods of different maturity levels, they pick them according to requirements. However, since the water depth in the lotus pond (field) is at least 30 cm or more, the silt hinders the feet, the lotus stalks are tall and obstructive to the eyes, and there are no ridges or ditches to judge the direction, resulting in limited vision and movement of workers in the lotus pond (field). They simply cannot move around at will to observe. The range and efficiency of manually harvesting lotus pods are limited. Therefore, the method of manually picking lotus pods by hand is not conducive to picking lotus pods in a large area at the same position. The labor intensity during the lotus pod picking process is large, and it is not convenient to pick. It is necessary to fix a certain route to harvest within a certain range along the way. Therefore, we propose a lotus pod harvesting device to solve the above-mentioned problems. Content of the Utility Model

The first support plate and the second support plate form a rotating structure, and the second support plate and the third support plate form a rotating structure. This design can use the picking device composed of the support plates to hook the lotus pods around the human body for picking, and can flexibly expand and retract the picking device, which is convenient for carrying.

[0010] Preferably, the lower ends of the second support plate and the third support plate are both inclined, and the contact parts of the second support plate and the third support plate with the positioning rod are both smooth. This design can facilitate the smooth sliding of the positioning rod on the support plate when the support plate is unfolded, and prevent it from blocking the unfolding of the support plate.

[0011] Preferably, the adjusting plates form an elastic structure through compression springs. One end of the adjusting plate penetrates through the fixed block and is slidably connected with the fixed block. This design can realize the flexible movement of the adjusting plate, so as to flexibly adjust the position of the positioning rod and realize the locking and unlocking between the support plates.

[0012] Preferably, one end of the positioning rod penetrating through the side wall of the fixed block is engaged with the positioning hole, and the positioning rod and the adjusting plate are perpendicularly distributed. This design can use the engaged positioning rod and positioning hole to lock the support plate in the unfolded state, which is convenient to use the support plate and cooperate with the harvesting hook to harvest the lotus pods.

[0013] Preferably, the first support plate and the third support plate are on the same side of the second support plate in the unfolded state, and the second support plate is located between the first support plate and the third support plate.
