Description

Technical Field

[0001] The utility model belongs to the technical field of walnut picking, and particularly relates to a lightweight walnut picker. Background Art

[0002] With the development of modern agriculture, mechanization, automation, and intelligence have become important trends in agricultural development. The research and development of walnut pickers exactly conforms to this trend, aiming to improve the efficiency and safety of walnut picking through mechanical means, reduce labor intensity, and increase picking efficiency.

[0003] In the Chinese patent with the publication number CN220897234U, a walnut picker is mentioned, which includes a picking part and a collection part. The picking part includes a telescopic rod and a picking cylinder. There is a picking cavity with an upper opening in the picking cylinder. A cutter head assembly for cutting walnuts is provided in the picking cavity. A discharge hose for discharging walnuts into the collection part is provided at the lower end of the picking cylinder. The collection part includes a collection box. A collection cavity communicated with the discharge hose is provided in the collection box. A screening assembly for screening walnuts is provided in the collection cavity. Through the setting of the collection part, the walnuts picked by the picking part can be collected. Compared with the existing walnut pickers without a collection part, the utility model can collect the walnuts picked by the picking part through the setting of the collection part, and there is no need to bend down to pick up the walnuts on the ground, thus reducing the work burden.

[0004] However, in the above technical solution, through the setting of the collection part, the walnuts picked by the picking part can be collected, and there is no need to bend down to pick up the walnuts on the ground. Although the above device can collect the picked walnuts, the walnut picking efficiency of this device is relatively low, it is easy to cause damage to walnuts during the picking process, and the operation process is relatively complicated. Therefore, it needs to be improved by the staff. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1:

[0026] Please refer to Figures 1 to 4 As shown, a lightweight walnut picker includes:

[0027] Telescopic rod 1;

[0028] The top of the telescopic rod 1 is fixedly connected with a vibration mechanism 2. One side of the top of the vibration mechanism 2 is fixedly connected with a clamping mechanism 3. One side of the vibration mechanism 2 is electrically connected with a controller 4. One side of the controller 4 is electrically connected with a power supply 5. Carry the picker to under the walnut tree, ensure that the power supply 5 is fully charged or connected to an external power supply 5, adjust the length of the telescopic rod 1 to adapt to walnut trees of different heights, and the operator holds the telescopic rod 1 by hand and brings the clamping mechanism 3 close to the branch;

[0029] The vibration mechanism 2 includes a frame 201, a first linear bearing 202, a slider 203, a push rod 204, a motor 205, a crank 206, a connecting rod 207, a second linear bearing 208, a bearing rod 209 and a rod sleeve 210. On one side of the surface of the frame 201, the first linear bearing 202 is fixedly connected. In the middle of the surface of the frame 201, the slider 203 is slidably connected. At the top of the back surface of the frame 201, the second linear bearing 208 is fixedly connected. The push rod 204 is slidably connected with the second linear bearing 208. On one side of the back surface of the frame 201, the motor 205 is fixedly connected. The output end of the motor 205 is rotationally connected with the crank 206. On one side of the surface of the crank 206, the connecting rod 207 is rotationally connected. On one side of the surface of the push rod 204, the bearing rod 209 is fixedly connected. On one side of the surface of the bearing rod 209, the rod sleeve 210 is sleeved, and one side of the surface of the rod sleeve 210 is slidably connected with the slider 203. Press the button on the controller 4 to start the motor 205. The motor 205 drives the crank 206 to rotate. The crank 206 drives the slider 203 to slide left and right on the frame 201 through the connecting rod 207. The push rod 204 is driven by the cam on the slider 203 to reciprocate up and down, so that the clamping mechanism 3 and the walnut branches vibrate together. The vibration generated by the vibration mechanism 2 is transmitted to the branches. After a period of vibration, the walnuts are separated from the branches, thus completing the picking.

[0030] Embodiment 2:

[0031] Please refer to Figures 1 to 4 As shown in the figure, the clamping mechanism 3 includes a clamping seat 301, a spring stopper 302, a spring 303 and a ball 304. On one side of the clamping seat 301, the spring stopper 302 is fixedly connected. On both sides of the inner wall of the clamping seat 301, the springs 303 are connected. The front ends of the springs 303 are connected with the balls 304, and one side of the surface of the balls 304 is inserted into the inner wall of the clamping seat 301. On one side of the inner wall of the clamping seat 301, a socket groove is opened, and an arc groove is opened on the inner wall of the socket groove. When the clamping mechanism 3 is close to the walnuts, the design of the balls 304 and the springs 303 in the clamping mechanism 3 enables the clamping seat 301 to easily clamp the branches without causing damage to them. Through the vibration of the vibration mechanism 2, the walnuts generate inertial force and fall off the branches. After the walnuts fall to the ground, they are picked up manually and placed in a collection container.

[0032] Embodiment 3:

[0033] Please refer to Figures 1 to 4As shown in the figure, carry the picker under the walnut tree, ensure that the power supply 5 is fully charged or connected to an external power supply 5, adjust the length of the telescopic rod 1 to adapt to walnut trees of different heights. The operator holds the telescopic rod 1 by hand and brings the clamping mechanism 3 close to the branch. The spherical beads 304 and the spring 303 in the clamping mechanism 3 are designed such that the clamping seat 301 can easily clamp the branch without causing damage to it. Press the button on the controller 4 to start the motor 205. The motor 205 drives the crank 206 to rotate. The crank 206 drives the slider 203 to slide on the frame 201 through the connecting rod 207, thereby making the ejector rod 204 reciprocate up and down, causing the clamping mechanism 3 and the branch to vibrate together. The vibration generated by the vibration mechanism 2 is transmitted to the branch, causing the walnuts to generate inertial force. After a period of vibration, the walnuts fall off. After the walnuts fall to the ground, they are picked up manually and placed into the collection container.

[0034] Working principle: The motor 205 drives the crank 206 to rotate. Through the connecting rod 207 mechanism, the rotational motion is converted into a linear reciprocating motion, driving the ejector rod 204 and the clamping mechanism 3 to vibrate. Using the elastic clamping principle of the spring 303 and the spherical beads 304, the branch can be firmly clamped and is not easily detached. At the same time, no damage will be caused to the tree body during the vibration process. The power supply 5 provides electrical energy for the motor 205, and the controller 4 is used to control the start and stop of the motor 205, facilitating the operator to operate according to needs.
