Backpack medlar-picking machine

[0013] The present invention will be described in detail below with reference to the drawings and embodiments.

[0014] Such as figure 1 , figure 2 As shown, the present invention adopts a combination of a backpack and a hand-held structure. It includes a backpack 1 which is made of hard and light materials, such as aluminum plates. A fruit collection box 2, an electric exhaust fan 3 and a storage battery 4 are placed in the backpack box 1; two straps 5 are bolted on the outside of the backpack box 1. The suction port of the electric exhaust fan 3 communicates with the fruit collection box 2 so that the fruit collection box 2 can generate negative pressure. There is another entrance on the fruit collection box 2 which is connected with a soft straw 6 which penetrates the carrying box 1. The soft straw 6 has a certain length, which can be suitable for medlar plants of different heights. A plurality of brackets 7 are provided on the periphery of the soft straw 6, and a handle 8 is supported by the bracket 7. In order to be convenient to hold, the handle 8 is made into a pistol type. In order to reduce the weight, the handle 8 does not need to completely protect the soft straw 6, but only needs to be set at the front end of the soft straw 6 to facilitate the lifting of the soft straw 6.

[0015] The front part of the handle 8 has two upper and lower flat surfaces, and a plurality of horizontally long holes 9 are opened on the upper and lower flat surfaces. There are also two upper fixing plates 10 and two lower fixing plates 11 with round holes 12 on them. The two upper fixing plates 10 can be fixed to the upper flat surface longitudinally side by side, and the two lower fixing plates 11 can be fixed to the lower flat surface longitudinally side by side by using screws to pass through the circular holes 12 and the horizontally long holes 9 respectively. Since the upper and lower two flat surfaces are provided with horizontally long holes 9, the distance between the two upper fixing plates 10 on the upper flat surface can be adjusted by loosening the screws. In the same way, the distance between the two lower fixing plates 11 can also be adjusted. Each upper fixing plate 10 and the corresponding lower fixing plate 11 below it constitute a group, and a rotating roller 12 is respectively arranged between each group of fixing plates, so there are two rotating rollers in total. One end of each roller 12 is connected to a fixed plate on one side through a bearing, and the other end is connected to the output shaft of the roller motor 13, and the roller motor 13 is fixed on the fixed plate on the other side, for example, One end of the roller 12 is fixed to the upper fixing plate 10, and the roller motor 13 is fixed to the lower fixing plate 11. Of course, it can also be arranged in reverse. The two rotating rollers 12 are vertically arranged side by side. Since the distance between the two upper fixing plates 10 and the distance between the two lower fixing plates 11 can be adjusted, the distance between the two rotating rollers 12 can also be adjusted. The rear ends of the two rollers 12 face the nozzle of the soft straw 6. A soft brush 14 is provided on the outer wall of each roller 12.

[0016] As a special description of the soft brush 14 on the roller 12, such as image 3 , Figure 4 As shown, a circle of holes is arranged every 5 mm in the length direction of the roller 12, and the hole positions between a circle of holes and another adjacent circle of holes are staggered at 30°, and in the same circle of holes, The interval angle between two adjacent holes is 60°. A soft brush 14 is fixed in each of the above-mentioned holes.

[0017] In order to realize automatic control of the entire device, a manual switch 15 is provided at the handle of the handle. The manual switch 15 forms a control loop with the battery 4, the electric exhaust fan 3, and the roller motor 13. The battery can be realized by turning the switch 15 by the wrench. 4 pairs of electric exhaust fan 3 and roller motor 13 work control.

[0018] When the present invention is working, the backpack 1 is manually carried on the back through the strap 5, a branch of mature fruit is picked up with the left hand, so that the wolfberry fruit hangs down at the lower end of the branch, and the handle 8 is held with the right hand, so that the roller 12 is aligned with the wolfberry At the end of the fruit, press the manual switch 15 with your right index finger at the same time, start the electric exhaust fan 3 and the two roller motors 13, so that the two rollers 12 rotate inward respectively, and at the same time make the soft straw 6 inhale inward, and the soft brush 14 The fruit on the branches is swept to separate the fruit from the branches. The fruit is sucked into the collection box 2 along the soft straw 6 under the action of suction. Then the right hand holds the handle 8 and slowly moves along the branches to complete the picking of a branch.
