Description

Technical Field

[0001] This utility model belongs to the field of walnut harvesting technology, specifically relating to a convenient walnut picking machine. Background Technology

[0002] Walnuts are usually harvested with their green husks on when they are ripe. When the fruit is ripe, bamboo poles or long, flexible wooden poles are used to knock the branches where the walnuts are located or to knock the fruit down directly, so that the green husks fall directly to the ground, and then they are picked up and collected.

[0003] Currently, walnut collection mainly relies on manual labor, where people bend over one by one to pick them up and place them in baskets. This method is characterized by long working hours, low efficiency, and high labor intensity. Some existing walnut-picking devices collect walnuts by sweeping. While this method can improve picking efficiency, it introduces dirt, fallen leaves, and other impurities during the picking process. This results in a higher level of impurities in the collected walnuts, increasing the number of subsequent processing steps and thus reducing overall work efficiency. Utility Model Content

[0004] To overcome the problems of long working hours, low efficiency, and high labor intensity associated with manually collecting walnuts one by one in the prior art, some existing walnut picking devices collect walnuts by sweeping. Although this can improve picking efficiency, it introduces impurities such as soil and fallen leaves during the picking process, resulting in a higher impurity content in the collected walnuts. This increases the number of subsequent processing steps and further reduces work efficiency. This utility model provides a convenient walnut picking machine. The picking mechanism sweeps walnuts from the ground into the guide shell, and under the pushing force of the pushing mechanism, the walnuts are thrown along the sieve plate into the collection box. This can automatically complete the picking and collection of walnuts, greatly reducing manual labor intensity and improving work efficiency. At the same time, the rotation of the wheel axle drives the cam to rotate, which in turn drives the sieve plate to swing back and forth, separating the walnuts from soil, fallen leaves, and other impurities, reducing the mixing of impurities and effectively reducing subsequent processing operations, further improving work efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A convenient walnut picking machine mainly includes a collection box, a picking mechanism, a pushing mechanism, a sieve plate, a guide shell, a wheel axle, a motor, an elastic component, a baffle shell, a support frame, a cam, a handrail, a drive wheel, and a traveling wheel. The support frame is installed at the front end of the collection box, and a baffle shell connected to the inlet of the collection box is installed obliquely on the support frame. The guide shell is installed at the front end of the baffle shell, the bottom end of the sieve plate is hinged to the bottom of the guide shell, and the top end is installed at the inlet of the collection box through an elastic component. An inclined material guiding channel is formed between the sieve plate and the baffle shell. A pushing mechanism for pushing walnuts is installed inside the material guiding shell. A motor connected to the pushing mechanism is installed on the outer wall of the material guiding shell. A picking mechanism is installed on the material guiding shell and connected to the pushing mechanism, located at the front end of the pushing mechanism. The axle is installed on the support frame through a bearing seat, located at the bottom of the sieve plate. A cam that contacts the bottom of the sieve plate is installed in the middle of the axle. A drive wheel is installed at the end of the axle. The axle is connected to the pushing mechanism. Two sets of walking wheels are installed on the side of the collection box. A handrail is installed at the rear end of the collection box.

[0006] The pushing mechanism includes a rotating shaft, a support plate, and a pushing plate. The rotating shaft is mounted on the guide shell via bearings. Support plates are installed at both ends of the rotating shaft, and a pushing plate is installed between the support plates. The rotating shaft is connected to a motor drive.

[0007] The picking mechanism includes a drive roller and levers. The end of the drive roller is mounted on the guide shell via bearings. Multiple sets of levers are evenly arranged on the drive roller along the circumferential direction. The end of the drive roller is connected to the rotating shaft via a chain drive mechanism.

[0008] The elastic component includes a guide rod, a spring, and a limiting nut. The top of the screen plate has a waist-shaped groove, the bottom end of the guide rod passes through the waist-shaped groove and is fixed to the collection box, and the top end is threaded to the limiting nut. The spring is sleeved on the guide rod, with its bottom end abutting against the screen plate and its top end abutting against the limiting nut.

[0009] The wheel axle is connected to the rotating shaft via a chain drive mechanism.

[0010] The top of the baffle shell is equipped with a battery that is electrically connected to the motor.

[0011] The beneficial effects of this utility model are:

[0012] This invention uses a picking mechanism to sweep walnuts from the ground into a guide shell. Under the pushing force of a pushing mechanism, the walnuts are thrown along a sieve plate into a collection box, automatically completing the picking and collection of walnuts. This greatly reduces the intensity of manual labor and improves work efficiency. At the same time, the rotation of the wheel axle drives the cam to rotate, which in turn drives the sieve plate to swing back and forth, separating the walnuts from impurities such as soil and fallen leaves. This reduces the mixing of impurities and effectively reduces the subsequent processing operations of the walnuts, further improving work efficiency. Attached Figure Description

A handrail 13 is installed at the rear end of the collection box 1. The pushing mechanism 3 includes a rotating shaft 301, a support plate 302, and a pushing plate 303. The rotating shaft 301 is mounted on the guide shell 5 through bearings. Both ends of the rotating shaft 301 are equipped with... The device is equipped with a support plate 302, and a pusher plate 303 is installed between the support plates 302. The rotating shaft 301 is connected to the motor 8 via a drive mechanism. The wheel axle 6 is connected to the rotating shaft 301 via a chain drive mechanism. The picking mechanism 2 includes a drive roller 201 and a lever 202. The end of the drive roller 201 is mounted on the guide shell 5 via a bearing. Multiple sets of levers 202 are evenly arranged on the drive roller 201 along the circumferential direction. The end of the drive roller 201 is connected to the rotating shaft 301 via a chain drive mechanism.

[0022] During use, the operator holds the handle 13 and turns on the power switch of the motor 8. The motor 8 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the pusher plate 303 to rotate through the support plate 302. At the same time, the rotating shaft 301 drives the wheel axle 6 and the transmission roller 201 to rotate through two sets of chain transmission mechanisms. The wheel axle 6 further drives the drive wheel 14 and the cam 12 to rotate, causing the device to move forward. The cam 12 drives the screen plate 4 to swing back and forth, separating the walnuts from impurities such as soil and fallen leaves, reducing the mixing of impurities and effectively reducing the subsequent processing operations of the walnuts, further improving work efficiency. During the forward movement of the device, the lever 202 on the transmission roller 201 pushes the walnuts on the ground into the guide shell 5. Then, under the pushing force of the pusher plate 303, the walnuts are thrown along the screen plate 4 into the collection box 1 for easy collection.

The spring 902 is sleeved on the guide rod 901, with its bottom end abutting against the sieve plate 4 and its top end abutting against the limiting nut 903. When the cam 14 rotates, the protruding part of the cam 14 periodically contacts the bottom of the sieve plate 4, pushing the sieve plate 4 to swing around the hinge point. During the upward swing of the sieve plate 4, the spring 902 is compressed and stores elastic potential energy. When the protruding part of the cam 14 leaves the bottom of the sieve plate 4, the spring 902 releases the elastic potential energy, causing the push plate 4 to swing downward and return to the initial position. The sieve plate 4 can reciprocate under the action of the cam 14 to achieve the function of screening out impurities such as soil and fallen leaves, reducing the subsequent processing operations of walnuts and further improving work efficiency.

[0024] The top of the baffle shell 10 is equipped with a storage battery 7 that is electrically connected to the motor 8; the storage battery 7 provides power to the motor, enabling it to work in the orchard and improving the portability of the device.

[0025] Work process:

[0026] During use, the operator holds the handle 13 and turns on the power switch of the motor 8. The motor 8 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the pusher plate 303 to rotate through the support plate 302. At the same time, the rotating shaft 301 drives the wheel axle 6 and the transmission roller 201 to rotate through two sets of chain transmission mechanisms. The wheel axle 6 further drives the drive wheel 14 and the cam 12 to rotate, causing the device to move forward. The cam 12 drives the screen plate 4 to swing back and forth, separating the walnuts from impurities such as soil and fallen leaves, reducing the mixing of impurities and effectively reducing the subsequent processing operations of the walnuts, further improving work efficiency. During the forward movement of the device, the lever 202 on the transmission roller 201 pushes the walnuts on the ground into the guide shell 5. Then, under the pushing force of the pusher plate 303, the walnuts are thrown along the screen plate 4 into the collection box 1 for easy collection. It can automatically complete the picking and collection of walnuts, greatly reducing the intensity of manual labor and improving work efficiency.
