Description
Technical Field
The utility model relates to a technological device, in particular to a pineapple auxiliary picking device.
Background
Because the pineapple leaf tips are hard and the leaf edges are accompanied by sawteeth, farmers need to wear protective clothing and eyeshields when picking pineapples to prevent the pineapple leaves from cutting the bodies. In the picking process, farmers need to cut pineapples off the plants by using a cutter and place the pineapples in a basket on the back. In the picking process, farmers need to carry the heavy basket and walk in the pineapple field with thorns spread all over, which causes a large amount of physical power consumption. The harvesting cost is about 40% of the pineapple planting process. With the advance of scientific and technological farmers in China, it is obvious that the mechanization of pineapple harvesting is vigorously developed, the structure adjustment of the agricultural industry is promoted, the income of farmers is increased, and the competitiveness of agricultural products is improved.
Under the environment of rapid development of orchard picking mechanization in China, the pineapple picking device still has the following defects:
1) in the traditional pineapple picking device, a fruit grower needs to squat down to use the device, so that the pineapple is picked for a long time and has high fatigue strength; in the traditional pineapple picking device, fruits need to be picked by matching with left and right wrestling of the wrist of a user, and the picking efficiency is low.
2) In the traditional pineapple picking device, when a pineapple is clamped, fingers need to overcome the resistance of a spring to slowly push a clamping switch, when the pineapple reaches a specified position, the clamping switch is pressed down to enable the pineapple to be self-locked, and after the cutting work is finished, the clamping switch is pressed down again to enable the pineapple to automatically recover to an initial state. In the process, the force needs to be from the clamping switch, to the push rod and then to the gear rack to realize the movement, so that the transmission stage is multiple and the energy loss is large. And the transmission ratio is more than 1, so that the device is a labor-consuming device, and the labor intensity of fingers is increased.
3) In traditional pineapple picking device, most of transmission structure are rack and pinion transmission, are difficult to process, and pinion bearing capacity is relatively weak, and fragile needs often to change the part.

This picking device compares and picks the device in the past, and its theory of operation is simpler, and the design more accords with human engineering, stands and can operate, and the operation is more convenient. The time cost is reduced, and the picking efficiency is improved, so that greater economic benefit is created for fruit growers.
2. The clamping force born by the pineapples can be accurately controlled according to the easiness in sensing of the clamping force of the clamping mechanism, and the pineapples are prevented from being damaged when the clamping force is too large; according to the fact that the power arm in the shearing mechanism is long and the stroke is long, the effect of saving labor can be achieved; the picking device is mainly composed of components such as ropes, pulleys and the like, and has light weight and low cost; the picking device is convenient for operating the device in a standing state by a fruit grower because the handle is far from the shearing cutter in the vertical direction; inverting the device picks fruit growing on trees, such as citrus fruits and the like.
3. In traditional pineapple picking device, most of transmission structure are rack and pinion transmission, are difficult to process, and pinion bearing capacity is relatively weak, and fragile needs often to change the part. After improvement, the weight is reduced to a great extent, and the machine is simple to process and assemble, low in cost, long in service life and simple to maintain.
