Description

Technical Field

[0001] The invention relates to the field of sowing, and in particular provides a novel potato sowing device. Background Art

[0002] Potato sowing is the process of placing potato seeds in the soil.

[0003] Potatoes bear fruit below the ground, so the seeds need to be placed below the ground. Traditional manual planting is labor-intensive and inefficient. With the continuous development of science and technology, potato machines have been used for automatic sowing. However, traditional potato sowing only adjusts the amount of material fed by the size of the feeding port when feeding. If there is a lot of accumulation, it is easy to get stuck at the feeding port, resulting in no material in some positions and more material in other positions, resulting in uneven sowing. When transmitting potato seeds, traditional machines are driven by motors, which consume a lot of energy after long-term use. Since there is a lot of starch on the surface of potato seeds, for the transmission device, if it is not cleaned regularly, the surface will be sticky with more starch, which will affect the subsequent feeding. Traditionally, it is cleaned manually, which is relatively troublesome. Therefore, in order to solve the above problems, it is necessary to design a new potato sowing device.

DETAILED DESCRIPTION

[0031] The present invention will be further explained below in conjunction with specific implementation schemes, but the present invention is not limited thereto.

[0032] like Figure 1-13As shown, the present invention provides a novel potato sowing device, comprising: a ridging mechanism, a soil covering mechanism, a sowing mechanism and a moving mechanism, wherein the sowing mechanism is located above the moving mechanism, the ridging mechanism is located in front of the moving drive mechanism, and the soil covering mechanism is located at the rear of the moving mechanism. The sowing mechanism comprises: a shell, a hopper 1, a main driving wheel 2, a secondary driving wheel 3, a cloth belt 4, a vibration wheel 5, a plurality of pairs of sowing spoons 6, an isolation screen 7, a sowing spoon cleaning brush 8, a left guide plate 9 and a right guide plate 10, the main driving wheel 2 and the secondary driving wheel 3 pass through the shell and are respectively located at the upper and lower ends of the shell, the cloth belt 4 is sleeved on the main driving wheel 2 and the secondary driving wheel 3, and the secondary driving wheel 3 is located at the lower end, the hopper 1 A retaining screen 11 is provided in the hopper 1 at the front side of the shell and close to the driven power wheel 3, and a material discharge gap is left between the lower end of the retaining screen 11 and the lower end of the hopper 1. Several pairs of seeding spoons 6 are fixedly connected to the cloth belt 4 and are staggered in pairs. The isolation screen 7 is located at the upper end of the shell to intercept the seeding spoon 6. The vibration wheel 5 is located in the shell and between the active power wheel 2 and the driven power wheel 3. The vibration wheel 5 overlaps the inner surface of the cloth belt 4. A reverser is provided between the vibration wheel 5 and the active power wheel 2. A discharge port connected to the lower end of the cloth belt 4 is provided at the lower end of the shell. The left guide plate 9 and the right guide plate 10 are arranged in the discharge port and are relatively placed. The sowing spoon cleaning brush 8 is located at the lower end of the shell and above the left guide plate 9 and the right guide plate 10. The main power wheel 2 and the driven power wheel 3 are both provided with driven gears at one end. When using this device, the ridge-opening mechanism is located at the lower end of the front side, so that the ridges can be opened first. The moving mechanism is followed and moved by external pulling on both sides, so that the device moves as a whole, and then sowing is carried out. After sowing, the soil covering mechanism on the rear side covers the sown ridges with soil, and makes the ridges into original trapezoidal ridges. The device is connected to an external driving device (such as a tractor), and is pulled and followed by the external driving device to move. When the sowing operation is carried out, the potato pieces are piled inside the hopper 1, and during the movement During the feeding process, the retaining screen 11 inside the hopper 1 is convenient for properly intercepting potatoes, so that the materials are discharged at a distance between the lower surface of the hopper 1, wherein the seeding spoon 6 located on the cloth belt 4 carries the potato pieces during continuous feeding, wherein the cloth belt 4 is mounted on the main power wheel 2 and the driven power wheel 3, and when rotating, the main power wheel 2 and the driven power wheel 3 make the cloth belt 4 rotate, and the potato pieces are driven by the seeding spoon 6 to rotate and transmit, wherein the reverser located between the vibration wheel 5 and the main power wheel 2 can transmit the rotation of the main power wheel 2 to the vibration wheel 5, but the direction of transmission is opposite, so when the cloth belt 4 rotates clockwise, the vibration wheel 5 rotates counterclockwise,During the continuous rotation, the cloth belt 4 is struck, so that the cloth belt 4 feels the vibration, and the seeding spoon 6 also feels the vibration. Since the shape of the seeding spoon 6 is similar to that of a human hand, the size of the potato piece is about the same as that of the seeding spoon 6. Therefore, after a long period of uniform vibration, only one potato piece is left in each seeding spoon 6, ensuring that the material is discharged more evenly when it is conveyed downward. Bearings and round shafts are provided at the connection between the vibration wheel 5 and the shell, which are convenient for rotating on the shell and conveying the potato pieces downward, and are dropped through the discharge port at the lower end of the hopper 1. A pair of left guide plates 9 and right guide plates 10 located in the shell and close to the discharge port are convenient for limiting the potato pieces on the left and right during discharge, so that the material is discharged only in the center. Each discharge port corresponds to the center of a ridge for discharging materials, wherein the isolation screen 7 located on the upper surface of the shell and above the sowing spoon 6 is only used to intercept the sowing spoon 6 carrying potato pieces when it is transported from the top to prevent overflow, wherein the sowing spoon cleaning brush 8 located at the lower end of the shell and overlapping with the sowing spoon 6 is convenient for cleaning the sowing spoon 6 after the sowing spoon 6 has finished discharging materials once, so that when the potato pieces are received again, the most original state is maintained to prevent the sticky starch inside from affecting the carrying of potato pieces, wherein the sowing spoon cleaning brush 8 is selected as a relatively hard brush, which is convenient for extending into the inside of the sowing spoon 6, and the cleaning is better during the rotation process, wherein the left guide plate 9 and the right guide plate 10 are only fixed to the shell, and can be connected by screws, etc.,
