Description
Technical Field
[0001] The present invention belongs to the technical field of potato seeding machinery, and particularly relates to a pre-sowing ridge surface compressing device for a single-row potato seeder. Background Art
[0002] With the development of agricultural modernization, as the fourth most important food crop globally, the planting scale of potatoes has been continuously expanding, and the requirements for seeding quality have become increasingly strict. In small-plot potato seeding operations, various types of small seeding machines are applied, among which single-row potato seeders are widely used due to their light structure and flexible operation. However, some single-row potato seeders need to carry out seeding operations on the basis of pre-ridged fields. During this process, the flatness of the ridge surface will affect the uniformity of seeding depth, and the uniformity of seeding depth is directly related to seeding quality. Therefore, in order to ensure seeding quality, it is necessary to carry out appropriate compressing operations on the ridge surface. Currently, traditional small-plot potato seeders have significant problems in the compressing link. They usually are equipped with a compressing device with a simple structure, which generally lacks an effective way to adjust the compressing depth. During the operation, it is very easy to cause excessive compaction of the soil, thereby destroying the soil structure; in addition, the stability of this device is poor, and it is prone to damage in a complex field operation environment, reducing the reliability of the machine. Therefore, designing a compressing device suitable for small-plot single-row potato seeders will help improve the quality of potato planting. Summary of the Invention
[0003] The purpose of the present invention is to provide a compressing device for a small-plot single-row potato seeder with adjustable compressing depth, good stability, good versatility, and suitable for low-speed operation, aiming at the problems mentioned above.
[0004] To achieve the above object, the present invention adopts the following technical solutions: The pre-sowing ridge surface compaction device of the single-row potato planter of the present invention includes a frame, a height adjustment frame, an angle adjustment frame, and a compaction roller assembly. The frame is the frame of the plot single-row potato planter, and the height adjustment sleeve is welded at the middle position of the front surface of the frame. The height adjustment frame is composed of a height adjustment main beam, a cross beam, a vertical beam, and an arc plate; the height adjustment main beam is fixed to the height adjustment sleeve by bolts; the cross beam is welded to the lower end of the height adjustment main beam; there are two arc plates, which are welded to the left and right sides of the height adjustment main beam respectively, and pin holes are provided on the arc plates; there are two vertical beams, and pin holes are provided at the lower ends, which are respectively welded to the left and right sides of the lower surface of the cross beam; the angle adjustment frame includes an angle adjustment main beam, a vertical beam, a U-shaped plate, and an adjustment plate; there are two vertical beams, and U-shaped grooves are provided at the lower ends, which are respectively welded to the left and right sides of the lower surface of the angle adjustment main beam; there are 4 U-shaped plates, and pin holes are provided above, and they are respectively welded to the left and right sides of the upper surface of the angle adjustment main beam in pairs, and are connected to the vertical beam by pins. The pin has a small hole, and an R-shaped split pin is inserted into the small hole to axially position the pin and connect the angle adjustment frame and the height adjustment frame; there are two adjustment plates, and pin holes are provided in the front, and they are welded to the middle position in front of the angle adjustment main beam and are connected to the arc plate by pins. An R-shaped split pin is inserted into the small hole of the pin to axially position the pin; the compaction roller assembly includes a compaction roller, a through shaft, a bearing, and a hole-type elastic retaining ring; the left and right ends of the compaction roller are welded with compaction roller flanges, and there are two bearings, which are respectively installed in the left and right compaction roller flanges, and axial positioning is achieved through the hole-type elastic retaining ring. The two ends of the through shaft are respectively installed in the U-shaped grooves at the lower ends of the vertical beams, and are respectively fixed by nuts and elastic washers.
[0005] As a further optimization or improvement of the present invention, the height adjustment sleeve is welded at the middle position of the front surface of the frame, and the height adjustment frame is fixed to the height adjustment sleeve by bolts. According to the operation requirements, the relative position in the vertical direction between the height adjustment frame and the height adjustment sleeve can be adjusted to adjust the compaction depth of the compaction device.
[0006] As a further optimization or improvement of the present invention, there are 11 pin holes provided on the arc plate. By adjusting the concentricity between the pin holes on the adjustment plate in the angle adjustment frame and different pin holes on the arc plate, hierarchical adjustment of the compaction depth is realized. When it is concentric with the lowermost pin hole, it represents the lowest compaction depth. For each upward adjustment of one hole, the compaction depth will increase by 1 cm. Taking the ridge height of 25 cm as an example, the compaction depth adjustment range is 0-15 cm. Through hierarchical adjustment, the adaptability of the compaction device to the ridge height is better.
[0007] As a further optimization or improvement of the present invention, two vertical beams are welded to the lower surface of the cross beam of the height adjustment frame, making the force on the entire compaction device more uniform and enabling the compaction device to work more stably.
[0008] As a further optimization or improvement of the present invention, the compaction roller assembly is composed of a compaction roller, a through shaft, bearings, and a circlip for hole. The two ends of the through shaft are respectively installed in the U-shaped grooves at the lower ends of the vertical beams, thereby connecting the compaction roller assembly with the angle adjustment frame, and the compaction roller can rotate around the through shaft.
[0009] Due to the adoption of the above technical solution, the pre-sowing ridge surface compaction device of the single-row potato planter provided by the present invention has the following beneficial effects compared with the prior art:
[0010] Since the present invention adds the left and right vertical beams below the height adjustment frame compared with the existing compaction device, the force on the compaction device is more uniform, it is not easily damaged, and it works more stably; by adjusting the relative position in the vertical direction between the height adjustment frame and the height adjustment sleeve, the compaction depth of the compaction device can be increased or decreased; by adjusting the concentricity of the pin hole on the adjustment plate in the angle adjustment frame and different pin holes on the arc-shaped plate, the hierarchical adjustment of the compaction depth is realized, improving the applicability of the compaction device, meeting the operation requirements of different soil types and different ridge heights, making the ridge surface smoother, ensuring the consistency of the sowing depth of potato planting, and improving the sowing quality and operation efficiency of the single-row potato planter.

Specific implementation mode
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes:
[0022] As Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown in the figures, it is a schematic diagram of the overall structure of a pre-sowing ridge surface pressing device for a single-row potato planter, including a frame 1 and a height adjustment sleeve 5 welded at the middle position of its front surface. Arc-shaped plates 21 are welded on the left and right sides of the main height adjustment beam 6 in the height adjustment frame 2. There are 11 pin holes on the arc-shaped plates 21. The cross beam 7 is welded to the lower end of the main height adjustment beam 6. Two vertical beams 8 are welded on the left and right sides of the lower surface of the cross beam 7. There are pin holes at the lower ends of the vertical beams 8; in the angle adjustment frame 3, two pairs of 4 U-shaped plates 13 are respectively welded on the left and right sides of the upper surface of the main angle adjustment beam 10. The U-shaped plates 13 are provided with pin holes. Two adjusting plates 22 are welded at the middle position in front of the main angle adjustment beam 10. Two vertical beams 12 are welded on the left and right sides of the lower surface of the main angle adjustment beam 10; the left and right ends of the pressing roller 11 are respectively welded with pressing roller flanges 17.
[0023] As Figure 3 As shown, bearings 25 are installed in the pressing roller flanges 17. Circlips for holes 19 are installed in the pressing roller flanges 17 to axially position the bearings 25 sleeved on the through shaft 15. The two ends of the through shaft 15 are respectively installed in the U-shaped grooves at the lower ends of the vertical beams 12, thereby connecting the pressing roller assembly 4 and the angle adjustment frame 3; the two ends of the through shaft 15 are respectively fixed by nuts 16 and elastic washers 18.
[0024] As Figure 4 As shown, the vertical beam 8 in the height adjustment frame 2 is connected to the U-shaped plate 13 on the angle adjustment frame 3 through a pin shaft 9. After connection, an R-shaped split pin 14 is inserted into the small hole of the pin shaft 9 to axially position the pin shaft 9.
[0025] As Figure 5As shown in the figure, the arc plate 21 in the height adjustment frame 2 and the adjustment plate 22 on the angle adjustment frame 3 are connected by a pin shaft 23. After connection, an R-shaped split pin 24 is inserted into the small hole of the pin shaft 23 to axially position the pin shaft 23.
[0026] As Figure 7 shown in the figure, the height adjustment main beam 6 is fixed to the height adjustment sleeve 5 by bolts 20. By adjusting the relative position in the vertical direction between the height adjustment main beam 6 and the height adjustment sleeve 5, the pressing depth of the pressing device can be adjusted.
[0027] The working principle of the present invention will be described below. The height adjustment sleeve 2 is welded to the frame 1 of the single-row potato planter. The height adjustment main beam 6 in the height adjustment frame 2 is fixed to the height adjustment sleeve 5 by bolts 20. Before work, by adjusting the relative position in the vertical direction between the height adjustment main beam 6 and the height adjustment sleeve 5, the pressing depth of the pressing device can be adjusted. On the lower surface of the cross beam 7 in the height adjustment frame 2, two vertical beams 8 are welded on the left and right sides, making the force on the entire pressing device more uniform and the work more stable. On the left and right sides of the height adjustment main beam 6 in the height adjustment frame 2, two arc plates 21 are welded. The arc plates 21 are provided with 11 pin holes. On the front surface of the angle adjustment main beam 10 in the angle adjustment frame 3, two adjustment plates 22 are welded. The adjustment plates 22 are provided with pin holes. By adjusting the angle between the angle adjustment frame 3 and the vertical plane, the pin holes on the adjustment plates 22 are made concentric with the pin holes on the arc plates 21. The adjustment plates 22 and the arc plates 21 are fixed by passing the pin shaft 23 through the concentric pin holes, and the R-shaped split pin 24 is inserted to axially position the pin shaft 23. By adjusting the pin holes on the adjustment plates 22 in the angle adjustment frame 3 to be concentric with different pin holes on the arc plates 21, the hierarchical adjustment of the pressing depth is realized. When it is concentric with the lowermost pin hole, it represents the lowest pressing depth. For each upward adjustment of one hole, the pressing depth will increase by 1 cm. Taking the ridge height of 25 cm as an example, the pressing depth adjustment range is 0 - 15 cm. Through hierarchical adjustment, the adaptability of the pressing device to the ridge height is better.
[0028] The present invention has the characteristics of good ridge surface leveling effect, strong stability, convenient adjustment, good versatility, and not easy to be damaged. It can meet the operation requirements of different soil types and different ridge heights, improve the sowing quality and operation efficiency of the single-row potato planter, ensure the certain depth of potato planting, make the ridge surface more flat, and obtain a good sowing effect.
[0029] The present invention is applicable to the pressing operation before sowing single-row potatoes in plots.
