[0002] my country is the largest producer of fruit trees and has a rich variety of fruit trees. Walnuts are widely planted. Xinjiang, the second largest walnut producing province (autonomous region), produces nearly 1.2 million tons of walnuts annually. As the main productive force of Xinjiang walnuts, the southern Xinjiang region has an annual walnut planting area increasing at a rate of 300,000 mu, and the walnut industry area has reached 6 million mu. At present, my country's total walnut production value and walnut planting area are both ranked first in the world.

[0003] Currently, walnut picking mostly relies on manual labor. Although the initial cost of manual labor is low, the walnut picking cycle is long, it is difficult to harvest in time, and the efficiency is low. Walnut picking operations are highly seasonal and labor-intensive. If the harvest is not timely, it will increase the infection of walnut mold, causing the walnuts to turn black and moldy, affecting the yield and quality of walnuts, thereby affecting the economic benefits of fruit farmers.

[0004] To sum up, how to solve the problem that walnut picking operations are highly seasonal and labor-intensive, and untimely harvesting will increase walnut mold infection, causing walnuts to turn black and moldy, affecting walnut yield and quality, and thus affecting the economic benefits of fruit farmers has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a new walnut collection all-in-one machine. Summary of the invention

[0056] The fourth wheel axle 21 is located inside the vehicle body 1 and is provided with a peeling cage 22. One side wall of the peeling cage 22 is fixedly welded to the inner wall of the vehicle body 1. A cleaning box 23 is fixedly welded to the side of the peeling cage 22 away from the side wall of the vehicle body 1.

[0060] A collecting assembly for collecting the peeled and cleaned walnuts is provided at the discharge port 27 .

[0061] The collecting assembly includes a collecting pipe 28 and a collecting box 29. One end of the collecting pipe 28 is connected to the cleaning box 23 through the discharge port 27. One side wall of the collecting box 29 is fixedly welded to the rear end of the vehicle body 1 in the moving direction. The end of the collecting pipe 28 away from the cleaning box 23 is connected to the collecting box 29. The collecting pipe 28 is inclined from the cleaning box 23 to the collecting box 29.

[0062] The specific implementation process is as follows:

[0063] The user starts the controller, and the controller sends a control signal to control the start of the driving member. The user drives the rotation of the driving wheel 2 and the steering wheel 3 through the driving pulley 4 to control the forward movement and steering of the vehicle body 1. In this embodiment, the driving member is a motor; when the motor output shaft rotates, it can drive the driving pulley 4 to rotate. At this time, the rotation of the driving pulley 4 can drive the third belt 18 and then drive the fifth pulley 33 to rotate; at this time, the rotation of the fifth pulley 33 can drive the third wheel shaft 14 to rotate, and the rotation of the third wheel shaft 14 can drive the conveyor pulley 15 and then drive the conveyor belt 16 to rotate; at this time, due to the rotation of the third wheel shaft 14, it can drive the fourth belt 32 to rotate and then drive the fourth pulley 20 to rotate and then drive the fourth wheel shaft 21 to rotate.

[0064] At the same time, the driving pulley 4 can also drive the second belt 11 to rotate and then drive the first pulley 8 to rotate. The first pulley 8 rotates and then drives the second pulley 17 to rotate. The rotation of the first pulley 8 and the second pulley 17 can drive the first wheel shaft 9 to rotate and then drive the toggle wheel 12 to rotate, so that one motor drives all rotating parts to rotate at the same time.

[0065] When the user drives the vehicle body 1 over the walnuts on the ground, the user controls the output shaft of the electric push rod 7 to extend through the controller, thereby driving the collecting arms 5 to relatively retract. At this time, the collecting arms 5 can drive the walnuts between the two collecting arms 5 to be collected and put into the vehicle body 1. In the process of the vehicle body 1 moving forward, the walnuts enter under the shifting wheel 12. At this time, the shifting wheel 12 can shift the walnuts to the conveyor belt 16. At the same time, the conveyor belt 16 can transport the walnuts to the funnel 26 and then fall into the peeling cage 22. At this time, the force point and force angle of a walnut are as follows: Fig. 9 As shown, through calculation, the force on a walnut is: f = 0.068N.

[0066] During the transportation of walnuts, other impurities on the surface of the walnuts will be separated to the ground through the through grooves 30 between every two shafts in the conveyor belt 16. At the same time, due to the vibration of the motor, the impurities can also be transmitted to the walnuts by the conveyor belt 16, so that the impurities on the surface of the walnuts are further separated.

[0067] Since the rotation of the fourth wheel shaft 21 can drive the blade 24 to rotate, the walnuts with green skin and those that are not completely peeled can be peeled; then, due to the inclined setting of the bottom of the peeling cage 22, the walnuts will enter the cleaning box 23 from the peeling cage 22 due to gravity, and the fourth wheel shaft 21 can also provide power to the wire brush 25, and the wire brush 25 will brush off the dandruff adhering to the surface of the walnuts. At the same time, water is filled in the cleaning box 23 in advance, and the peeled walnuts can be cleaned in the cleaning box 23. Then, due to the inclined setting of the bottom of the cleaning box 23, the collecting pipe 28 is inclined from the cleaning box 23 to the collecting box 29; at this time, the cleaned walnuts can enter the collecting box 29 from the collecting pipe 28 from the discharge port 27 for collection.

[0068] Embodiment 2:

[0069] As attached Figure 1 As shown, the difference from Example 1 is that the end of the collecting arm 5 away from the vehicle body 1 is fixedly connected to the infrared sensor 31 by screws, and the controller is used to receive the infrared obstacle avoidance signal sent by the infrared sensor 31.

[0070] The specific implementation process is as follows: the infrared sensor 31 can detect obstacles such as garbage in front of the vehicle body 1, and send an infrared obstacle avoidance signal to the controller. The controller sends a control signal to control the output shaft of the electric push rod 7 on the corresponding collecting arm 5 to extend and push the collecting arm 5 to bypass the obstacles and prevent garbage and other impurities from entering the vehicle body 1.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
