Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural picking, and specifically relates to a portable double-roller oil-tea fruit picking device. Background Art
[0002] Camellia oleifera is one of my country's important oil crops, belonging to the genus Camellia in the family Theaceae. It generally refers to tree species with a high oil content and certain planting value and economic benefits. Currently, the main methods of harvesting camellia oleifera in my country are manual harvesting and mechanized harvesting. In manual harvesting, pickers pick camellia oleifera from the tree with their bare hands and place them into collection devices such as backpacks and snakeskin bags. This is slow, labor-intensive, and has low economic benefits. The current mainstream mechanized harvesting of camellia oleifera is the vibrating camellia oleifera harvesting device, which has a high picking efficiency but high energy consumption, and the clamping mechanism clamps the branches, causing vibration that can easily damage the branches.

The crossbeam 19 of the picking head base is a columnar structure. The rubber roller 8 is a shaft-like part with an outer diameter at both ends smaller than the outer diameter in the middle. The transmission rod 6, the telescopic rod 5 and the holding rod 2 are all slender shaft-like parts. The electric push rod 1 adopts the existing technology, and its connection method and working principle are no longer described here.
[0042] In the present invention, the collecting net 10 is fixed on the left and right two end rubber roller support plates 11 located on the front side or fixed on the left and right two end rubber roller support plates 11 located on the rear side, that is, the two end rubber roller support plates 11 connected to the collecting net 10 are respectively installed on one end of the two connecting plates 9 and are located on the same side.

[0044] The utility model is provided with three rubber rollers 8. Compared with two rubber rollers that can only pick the oil-tea fruits on a single layer of branches by opening and closing at one time, the two rubber rollers 8 located on the rubber roller support plates 11 at both ends of the utility model open and close at the same time, which increases the opening and closing angle and can pick the upper and lower layers of oil-tea branches at the same time, thereby improving the picking efficiency; the telescopic mechanism adopts rollers 18 and rollers 17 as intermediate transmission components, which greatly reduces the friction resistance when the telescopic mechanism drives the picking mechanism to open and close, and the transmission efficiency is high; the degree of modularization is high, the functional allocation of the picking mechanism and the telescopic mechanism is clear, and the damage of a single mechanism does not affect the function of the other mechanisms; the plate-shaped parts provided in the utility model all adopt rounded corner transition, which reduces the resistance of the picking device to shuttle through the oil-tea branches, reduces the labor intensity of manpower and damage to the oil-tea tree; the telescopic stroke of the utility model mainly depends on the length of the slide 29 and the stroke of the electric push rod 1. When the stroke of the electric push rod 1 is surplus, the limit value of the opening and closing angle can be adjusted by designing slide grooves 29 of different lengths, and the adjustability is good. It has the characteristics of high picking efficiency, high transmission efficiency, high degree of modularization and good adjustability.
[0045] The working principle of the utility model is as follows: when the utility model is used, first connect a 12V lithium battery and an electric push rod remote control to the electric push rod 1 through a cable, and press the extension button and retraction button of the remote control to confirm whether the electric push rod 1 and the telescopic mechanism and the picking mechanism can work normally. After confirmation, hold the lower part of the holding rod 2 close to the oil tea tree. When picking, you can also use the strap to carry the device on your shoulder to reduce the weight. By pressing the extension button of the electric push rod remote control, the telescopic end of the electric push rod 1 is extended to make the telescopic rod 5 and the transmission rod 6 move upward, and the transmission rod 6 pushes the slide plate 13 to move upward. At the same time, the roller 18, the roller 17 and the limit The sheet metal 14 makes a planar motion in the direction of both sides of the slide 29 and the vertical direction, and then transmits the motion to the rubber roller support plates 11 at both ends through the roller pin 15, so that they are opened, and the picking mechanism is extended into the oil-tea branches. After the position is suitable, press the remote control retraction button of the electric push rod to retract the telescopic end of the electric push rod 1, so that the telescopic rod 5 and the transmission rod 6 move downward, and the roller 18 moves along the inner side of the slide 29, so that the rubber roller support plates 11 at both ends are closed, clamping the oil-tea branches and oil-tea fruits, and pulling back with the arms, the oil-tea fruits in the gap between the rubber rollers 8 are pulled down and dropped into the collection net 10, completing the harvesting of the oil-tea fruits.
