Technical Field
[0001] This utility model belongs to the field of potato planting machinery technology, specifically relating to a pre-planting ridge compaction device for a single-row potato planter. Background Technology
[0002] With the modernization of agriculture, potatoes, as the world's fourth most important food crop, are seeing increasingly larger planting scales and stricter requirements for planting quality. In small-scale potato planting operations, various types of small planting machines are used, among which single-row potato planters are widely used due to their lightweight structure and flexible operation. However, some single-row potato planters require planting on pre-ridged surfaces. During this process, the flatness of the ridge surface affects the uniformity of planting depth, which directly relates to planting quality. Therefore, to ensure planting quality, appropriate compaction of the ridge surface is necessary. Currently, traditional small-scale potato planters have significant problems in the compaction process. They are usually equipped with simple compaction devices that generally lack effective methods for adjusting compaction depth, easily leading to excessive soil compaction and damage to soil structure. Furthermore, these devices lack stability and are prone to damage in complex field conditions, reducing the reliability of the machine. Therefore, designing a compaction device suitable for single-row potato planters in small-scale planting areas will help improve potato planting quality. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems by providing a compaction device for single-row potato planters in small plots that features adjustable compaction depth, good stability, versatility, and suitability for low-speed operation.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: The pre-planting ridge compaction device for a single-row potato planter of this utility model includes a frame, a height adjustment frame, an angle adjustment frame, and a compaction roller assembly. The frame is a single-row potato planter frame, with a height adjustment sleeve welded to the middle of the front surface of the frame. The height adjustment frame consists of a height adjustment main beam, a crossbeam, an upper vertical beam, and an arc-shaped plate. The height adjustment main beam is fixed to the height adjustment sleeve by bolts. The crossbeam is welded to the lower end of the height adjustment main beam. There are two arc-shaped plates, welded to the left and right sides of the height adjustment main beam, with pin holes on the arc-shaped plates. There are two upper vertical beams, each with pin holes at the lower end, welded to the left and right sides of the lower surface of the crossbeam. The angle adjustment frame includes an angle adjustment main beam, a lower vertical beam, a U-shaped plate, and an adjustment plate. There are two lower vertical beams, each with a U-shaped groove at the lower end, welded to the left and right sides of the lower surface of the angle adjustment main beam. There are four profile plates, each with a pin hole at the top. They are welded in pairs to the left and right sides of the upper surface of the angle-adjusting main beam, respectively, and connected to the upper vertical beam via large pins. Each pin has a small hole into which an R-shaped cotter pin is inserted for axial positioning, connecting the angle-adjusting frame and the height-adjusting frame. There are two adjustment plates, each with a pin hole at the front, welded to the center of the front of the angle-adjusting main beam, and connected to the arc-shaped plate via small pins. An R-shaped cotter pin is inserted into the small hole of the small pin for axial positioning. The press roller assembly includes a press roller, a through shaft, bearings, and elastic retaining rings for holes. Press roller flanges are welded to both ends of the press roller. Two bearings are installed in the left and right press roller flanges, respectively, and are axially positioned using elastic retaining rings for holes. The through shaft is installed at both ends in U-shaped grooves at the lower end of the lower vertical beam, and is fixed at both ends by nuts and elastic washers.
[0005] As a further optimization or improvement of this utility model, the height adjustment sleeve is welded to the middle position of the front surface of the frame, and the height adjustment frame is fixed to the height adjustment sleeve by bolts. The vertical relative position between the height adjustment frame and the height adjustment sleeve can be adjusted according to the operation requirements to adjust the pressing depth of the pressing device.
[0006] As a further optimization or improvement of this utility model, the arc-shaped plate is provided with 11 pin holes. By adjusting the pin holes on the adjustment plate in the angle adjustment frame to be concentric with different pin holes on the arc-shaped plate, the compaction depth can be adjusted in stages. When concentric with the lowest pin hole, the compaction depth is the lowest. Each time the hole is adjusted upwards, the compaction depth will increase by 1cm. Taking a ridge height of 25cm as an example, the compaction depth adjustment range is 0-15cm. Through staged adjustment, the compaction device becomes more adaptable to the ridge height.
[0007] As a further optimization or improvement of this utility model, two upper vertical beams are welded to the lower surface of the crossbeam of the height adjustment frame, making the force on the entire pressing device more uniform and the pressing device more stable in operation.
[0008] As a further optimization or improvement of this utility model, the press roller assembly consists of a press roller, a through shaft, a bearing, and a retaining ring for the hole. The two ends of the through shaft are respectively installed in the U-shaped groove at the lower end of the lower vertical beam, thereby connecting the press roller assembly and the angle adjustment frame. The press roller can rotate around the through shaft.
[0009] By adopting the above technical solution, the pre-planting ridge compaction device for a single-row potato planter provided by this utility model has the following advantages compared with the prior art:
[0010] Compared to existing compaction devices, this invention adds left and right upper vertical beams below the height adjustment frame, resulting in more even force distribution, reduced damage, and greater stability during operation. By adjusting the vertical relative position between the height adjustment frame and the height adjustment sleeve, the compaction depth can be increased or decreased. Furthermore, by adjusting the concentricity of the pin holes on the adjustment plate of the angle adjustment frame with different pin holes on the arc-shaped plate, graded adjustment of the compaction depth can be achieved, improving the applicability of the compaction device. It can meet the operational requirements of different soil types and ridge heights, resulting in a smoother ridge surface, ensuring consistent planting depth for potatoes, and improving the planting quality and operational efficiency of single-row potato planters.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0022] like Figure 1 , Figure 2 , Figure 6 , Figure 8 The diagram shows the overall structure of a pre-planting ridge compaction device for a single-row potato planter. It includes a frame 1 and a height adjustment sleeve 5 welded to the middle of its front surface. The height adjustment frame 2 has an arc-shaped plate 21 welded to the left and right sides of the height adjustment main beam 6, with 11 pin holes on the arc-shaped plate 21. A crossbeam 7 is welded to the lower end of the height adjustment main beam 6, and two upper vertical beams 8 are welded to the left and right sides of the lower surface of the crossbeam 7, with pin holes at their lower ends. In the angle adjustment frame 3, four U-shaped plates 13 are welded in pairs to the left and right sides of the upper surface of the angle adjustment main beam 10, with pin holes on the U-shaped plates 13. Two adjustment plates 22 are welded to the middle of the front of the angle adjustment main beam 10, and two lower vertical beams 12 are welded to the left and right sides of the lower surface of the angle adjustment main beam 10. Compactor flanges 17 are welded to the left and right ends of the compaction roller 11.
[0023] like Figure 3 As shown, a bearing 25 is installed in the press roller flange 17. An elastic retaining ring 19 is installed in the press roller flange 17 to axially position the bearing 25 fitted on the through shaft 15. The two ends of the through shaft 15 are respectively installed in the U-shaped groove at the lower end of the lower vertical beam 12, thereby connecting the press roller assembly 4 and the angle adjustment frame 3. The two ends of the through shaft 15 are fixed by nuts 16 and elastic washers 18 respectively.
[0024] like Figure 4 As shown, the upper vertical beam 8 in the height adjustment frame 2 is connected to the U-shaped plate 13 on the angle adjustment frame 3 by a large pin 9. After connection, an R-type cotter pin 14 is inserted into the small hole of the large pin 9 to axially position the large pin 9.
[0025] like Figure 5As shown, the arc plate 21 in the height adjustment frame 2 is connected to the adjustment plate 22 on the angle adjustment frame 3 by a small pin 23. After connection, an R-type cotter pin 24 is inserted into the small hole of the small pin 23 to axially position the small pin 23.
[0026] like Figure 7 As shown, the height-adjusting main beam 6 is fixed to the height-adjusting sleeve 5 by bolts 20. The pressing depth of the pressing device can be adjusted by adjusting the vertical relative position between the height-adjusting main beam 6 and the height-adjusting sleeve 5.
[0027] The working principle of this utility model is explained below. The height adjustment sleeve 5 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 operation, the compaction depth of the compaction device can be adjusted by adjusting the vertical relative position between the height adjustment main beam 6 and the height adjustment sleeve 5. Two upper vertical beams 8 are welded to the left and right sides of the lower surface of the crossbeam 7 in the height adjustment frame 2, so that the force on the entire compaction device is more even and the operation is more stable. Two arc-shaped plates 21 are welded to the left and right sides of the height-adjusting main beam 6 in the height-adjusting frame 2. Each arc-shaped plate 21 has 11 pin holes. Two adjusting plates 22 are welded to the front surface of the angle-adjusting main beam 10 in the angle-adjusting frame 3. Each adjusting plate 22 has pin holes. By adjusting the angle of the angle-adjusting frame 3 relative to the vertical plane, the pin holes on the adjusting plates 22 are made concentric with the pin holes on the arc-shaped plates 21. A small pin 23 passes through the concentric pin holes to fix the adjusting plates 22 and arc-shaped plates 21. An R-type cotter pin 24 is inserted to axially position the small pin 23. By adjusting the concentricity of the pin holes on the adjusting plates 22 in the angle-adjusting frame 3 with different pin holes on the arc-shaped plates 21, the compaction depth can be adjusted in stages. Concentricity with the lowest pin hole represents the lowest compaction depth. Each upward adjustment increases the compaction depth by 1 cm. Taking a ridge height of 25 cm as an example, the compaction depth adjustment range is 0-15 cm. By adjusting the gradation, the compaction device becomes more adaptable to the ridge height.
[0028] This invention features good ridge leveling effect, strong stability, convenient adjustment, good versatility, and is not easily damaged. It can meet the operational requirements of different soil types and different ridge heights, improve the sowing quality and operational efficiency of single-row potato planters, ensure the consistency of potato planting depth, make the ridge surface flatter, and achieve good sowing results.
[0029] This invention is applicable to the compaction operation before planting single-row potatoes in a small plot.
