[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Reference drawings Figure 1 - Appendix Figure 2 In the embodiment one, the walnut fruit picking auxiliary tool has a frame 1, a chamber 2 for containing fruits and an opening 3 on the top surface, the opening 3 is communicated with the chamber 2; a fixed roller 4 is rotationally arranged on the frame 1 and partially exceeds the opening 3 outward; a movable roller 5 is slidingly arranged on the frame 1 and partially exceeds the opening 3 outward; a support rod 11 is fixedly connected to the bottom of the frame 1 and used for controlling the frame 1 to move in the air by the picker.

[0027] The two ends of the fixed roller 4 and the movable roller 5 are coaxially fixedly connected with the fixed shaft 7, the fixed shaft 7 between the fixed roller 4 and the frame 1 is rotationally connected, the fixed shaft 7 of the movable roller 5 extends into the chute 6 and is slidingly connected with the chute 6, the length of the fixed roller 4 and the movable roller 5 is same with the shortest straight line distance between the two chutes 6, the outer edge of the fixed roller 4 and the movable roller 5 is fixedly sleeved with the rubber ring 10, the friction coefficient of the rubber ring 10 is greater than that of the outer edge of the fixed roller 4 and the movable roller 5.

[0028] The driving device is installed outside the frame 1, the output end is coaxially fixedly connected with the fixed roller 4 and used for driving the fixed roller 4 to rotate, the driving device is the motor 8 and the speed reducer 9, the speed reducer 9 is fixedly installed outside the frame 1, the output end of the speed reducer 9 is coaxially fixedly connected with one of the fixed shafts 7 of the fixed roller 4, the motor 8 is fixedly connected with the speed reducer 9, the output end of the motor 8 is fixedly connected with the input end of the speed reducer 9.

[0029] The frame 1 is provided with two chutes 6, the chute 6 has a first end portion and a second end portion, the first end portion is higher than the second end portion, the movable roller 5 is slidingly arranged along the chute 6, under the action of gravity, the movable roller 5 always has a tendency to move towards the second end portion.

[0030] When the walnut fruit picking auxiliary tool is actually used, the picker first holds the support rod 11 fixedly connected to the bottom of the frame 1 and moves the frame 1 in the air to the position of the walnut fruits.

[0031] In this embodiment, the fixed roller 4 on the frame 1 is driven by a drive device, such as a motor 8 driving a reduction gearbox 9, and its fixed shaft 7 rotates stably on the frame 1. Under the action of gravity, the fixed shaft 7 of the moving roller 5 slides along the inclined groove 6 from the first end to the second end, cooperating with the rotating fixed roller 4, thereby rolling the fruit that is in contact between the fixed roller 4 and the moving roller 5 into the chamber 2 to complete the harvesting. (Refer to the attached diagram.) Figure 2 The arrow on the fixed roller 4 indicates the direction of rotation of the fixed roller 4. The sliding setting of the moving roller 5 allows the distance between the moving roller 5 and the fixed roller 4 to be adjusted, so that fruits of various sizes can be picked. Due to the setting of the inclined groove 6, the moving roller 5 always slides towards the fixed roller 4, thereby effectively clamping the fruit and completing the picking better. Of course, a minimum distance with gaps can also be set between the fixed roller 4 and the moving roller 5. The setting of this gaps avoids rolling the leaves as much as possible while picking the fruit. The lengths of the fixed roller 4 and the moving roller 5 are the same as the shortest straight distance between the two inclined grooves 6, ensuring that the moving roller 5 is prevented from deviating when sliding and can work effectively together. The drive equipment consisting of the motor 8 and the reduction gearbox 9 stably provides rotational power to the fixed roller 4 to ensure the continuous picking work. The reduction ratio of the reduction gearbox 9 is 1:10.

[0032] The frame 1 can be made of lightweight and sturdy aluminum alloy, and its internal chamber 2 is of moderate size to hold multiple walnut fruits within the reach of the picker.

[0033] The fixed shafts 7 at both ends of the fixed roller 4 and the moving roller 5 are made of stainless steel and have been polished.

[0034] Reference Appendix Figure 3 -Appendix Figure 4 Example 2 is an improvement on Example 1. Multiple equally spaced annular grooves 12 are opened in the rubber ring 10 of the fixed roller 4. Multiple arc-shaped plates 13 are set in each annular groove 12. The arc-shaped plates 13 are connected to the outer edge of the fixed roller 4. The side of the arc-shaped plates 13 facing outward is provided with a hook surface with barbs.

[0035] A vertical rod 14 is fixedly connected to the other side of the arc plate 13. A cylinder 15 is slidably connected to the vertical rod 14. The cylinder 15 is fixedly connected to the outer edge of the fixed roller 4. A limit ring 16 is fixedly sleeved on the outer wall of the vertical rod 14.

The elastic coefficient of the spring 17 inside the cylinder 15 that cooperates with it is set so that the arc-shaped plates 13 cannot crush the fruit.

[0037] The rubber ring 10 fixedly sleeved with the outer edge of the fixed roller 4 and the movable roller 5 increases the friction force when contacting with the fruits, and improves the picking efficiency, wherein the arc-shaped plate 13 arranged in the ring groove 12 of the rubber ring 10 of the fixed roller 4 is arranged in a plurality of equidistant rows, and the hook face with hooks on the outer side of the arc-shaped plate 13 can better grasp the fruits;

[0038] When the fruits contact with the fixed roller 4, the arc-shaped plate 13 is extruded, the vertical rod 14 fixedly connected on the other side of the arc-shaped plate 13 slides in the cylinder body 15, and the compression spring 17 is compressed, after the fruits pass into the chamber 2, the elastic force of the spring 17 makes the arc-shaped plate 13 reset, and is ready for the next picking, so that the hook face can grasp the fruits, and the fruits are not damaged due to the extrusion of the hook face, the outer surface of the fruits of the Juglans mandshurica is covered with hairs, the fruits are spherical, oval or ellipsoidal, the top end is sharp, and the fruits are densely covered with glandular short hairs, so that the fruits are easily grasped by the hook face structure similar to the magic tape.
