[0034] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] like Figures 1 to 10 As shown, one embodiment of this utility model provides a potato planting mechanism for hilly and mountainous areas, including a frame body 1 and a potato seed storage and conveying component 2, a contour ridging component 3, a field ridge shaping component 4, a implement lifting and connecting component 5, and a boot-type furrow opener 6 installed on the frame body 1; the frame body 1 includes a frame longitudinal beam 11, a frame crossbeam 12, a tie rod 13, a mounting base 14, a connecting crossbeam 15, a first support beam 16, a front connecting plate 17, a second support beam 18, and a third support crossbeam 19; the potato seed storage and conveying component 2 is connected between the first support beam 16 and the third support crossbeam 19, the contour ridging component 3 is connected to the bottom end of the frame crossbeam 12, the field ridge shaping component 4 is connected to the front end of the connecting crossbeam 15, the implement lifting and connecting component 5 is connected to the front connecting plate 17, and the boot-type furrow opener 6 is connected to the frame longitudinal beam 11.

[0038] In this invention, the potato planting mechanism integrates key components such as a seed storage and conveying assembly 2, a contour ridging assembly 3, a ridge shaping assembly 4, a implement lifting and connecting assembly 5, and a boot-type furrow opener 6 through the frame body 1, forming a fully functional planting system. The structural design of the frame body 1 ensures the stable installation and coordinated operation of each component. The seed storage and conveying assembly 2 is responsible for precise planting, while the contour ridging assembly 3 and the ridge shaping assembly 4 can flexibly adjust their operating states according to changes in terrain to ensure ridging and shaping effects. The implement lifting and connecting assembly 5 facilitates connection with power equipment and enables overall lifting, while the boot-type furrow opener 6 provides suitable seed furrows for planting.

[0039] In one embodiment, such as Figures 1 to 4As shown, the seed storage and conveying assembly 2 includes a seed storage box 21, a seed collection box 22, and a seed collection component 23 connected to the seed collection box 22, arranged in sequence. The seed storage box 21 is connected to the first support beam 16, and the seed collection mounting plate 231 on the seed collection component 23 is connected to the third support beam 19. An adjustable side plate 24 is slidably connected to the inner wall of the seed storage box 21. Understandably, the seed storage box 21 has an opening at the bottom, and the adjustable side plate 24 can slide on the inner wall of the seed storage box 21 through a sliding structure such as bolts, slide rails, and sliders to adjust the height of the adjustable side plate 24 from the ground (or from the bottom wall of the seed storage box 21). This controls the speed at which the seeds fall from the seed storage box 21 into the seed collection box 22, avoiding difficulties in seed collection due to excessive seeds in the seed collection box 22. Understandably, when it is necessary to reduce the seed flow rate, the adjusting side plate 24 can be slid upward to reduce the area of ​​the seed outlet; conversely, when it is necessary to increase the seed flow rate, the adjusting side plate 24 can be slid downward to increase the area of ​​the seed outlet.

[0040] In one embodiment, such as Figures 5 to 6 As shown, the seed-collecting assembly 23 includes a housing 232, a drive sprocket 233 and a driven sprocket 234 arranged opposite each other on the outer wall of the housing 232, a transmission chain 235 meshing with the drive sprocket 233 and the driven sprocket 234, and a plurality of seed-collecting scoops 236 connected to the transmission chain 235; the driven sprocket 234 is connected to a second drive shaft 237, and the drive sprocket 233 is connected to a first drive shaft 238; a drive motor 25 connected to the first drive shaft 238 is also installed on the outer wall of the seed-collecting box 22. Understandably, the drive motor 25 can drive the shaft of the drive sprocket 233 and the drive sprocket 233 to rotate via a coupling, thereby driving the transmission chain 235 and the seed-collecting scoops 236 to circulate. The seed-collecting scoops 236 scoop up potato seeds as they pass through the seed-collecting box 22, and after being lifted by the chain to the planting position, they are tilted. The periodic motion of the chain drive ensures a stable seed-taking frequency, and the spacing of the seed-taking spoons 236 allows for precise control of the amount of seeds taken in a single session.

[0041] In one embodiment, such as Figure 7 As shown, the contour ridging assembly 3 includes a base plate 31, a top plate 32, and ridging discs 33 symmetrically mounted at opposite ends of the base plate 31; the top plate 32 is welded to the frame crossbeam 12. Understandably, the ridging discs 33, symmetrically mounted at both ends of the base plate 31, can effectively turn and shape the soil during movement, forming neat ridges. The top plate 32, welded to the frame crossbeam 12, provides stable support for the entire assembly, ensuring operational stability in complex terrain.

[0042] In one embodiment, such as Figure 7As shown, the contour ridging assembly 3 also includes an elastic component installed between the base plate 31 and the top plate 32. The elastic component includes at least one screw 34 threaded between the base plate 31 and the top plate 32, a nut 35 threaded to the screw 34, and a first spring 36 sleeved on the screw 34. Understandably, the contour ridging assembly 3 dynamically adjusts the working state of the ridging disc 33 through an elastic adaptive structure: the base plate 31 and the top plate 32 form an elastic support system through the screw 34, nut 35, and first spring 36. When the machine travels to a slope, the ridging disc 33 floats up and down due to the terrain reaction force. When going uphill, the ridging disc 33 is subjected to upward pressure from the ground, compressing the first spring 36, and causing the ridging disc 33 to move upward; when going downhill, the ridging disc 33 moves downward due to its own weight, and the first spring 36 extends. This elastic adjustment mechanism allows the ridging disc 33 to flexibly adapt to ground undulations, maintaining stable contact with the soil at all times, thereby accurately completing the ridging operation. It effectively avoids ridging failure or poor quality caused by terrain changes, ensures the continuity and consistency of ridging operations, and significantly improves the performance and quality of potato planters in complex terrain.

[0043] In one embodiment, such as Figure 8 As shown, the ridge shaping component 4 includes a set of side plate mounting plates 41, a horizontal tube 42 connected between the set of side plate mounting plates 41, a first ridge shaping side plate 43 and a second ridge shaping side plate 44 mounted on the side plate mounting plates 41 and located below the horizontal tube 42, a first ridge smoothing horizontal plate 45 and a second ridge smoothing horizontal plate 46 connected between the first ridge shaping side plate 43 and the second ridge shaping side plate 44, and an elastic limiting component 47 connected between the horizontal tube 42 and the first ridge smoothing horizontal plate 45; the side plate mounting plates 41 are connected to the connecting beam 15 by U-bolts. Understandably, the width of the ridge can be controlled by adjusting the installation distance of the side plate mounting plates 24 on the connecting beam 15. The first ridge shaping side plate 43 and the second ridge shaping side plate 44 are fixedly installed to their respective connected side plate mounting plates 41 by bolts. Multiple mounting holes 411 are provided on the side plate mounting plates 41 for installing the first ridge shaping side plate 43 and the second ridge shaping side plate 44. Thus, the installation height of the first ridge shaping side plate 43 and the second ridge shaping side plate 44 on the side plate mounting plates 41 can be adjusted according to actual needs. The first ridge smoothing horizontal plate 45 and the second ridge smoothing horizontal plate 46 are both bent plates (not shown in the figure). The outer bent plate (not shown in the figure) has a round hole (not shown in the figure), and the inner bent plate has a U-shaped groove. The length of the connection between the first ridge smoothing horizontal plate 45 and the second ridge smoothing horizontal plate 46 can be adjusted by bolts, thereby adjusting the width of the ridge.

[0044] In one embodiment, such as Figure 8As shown, the elastic limiting component 47 includes an adjusting tube 471 fixedly connected to the horizontal tube 42, a limiting tube 472 inserted into the adjusting tube 471 and slidably connected to the adjusting tube 471, a connecting longitudinal plate 473 mounted on the first ridge leveling horizontal plate 45 and hinged to the limiting tube 472, and a second spring 474 mounted between the limiting tube 472 and the connecting longitudinal plate 473. Understandably, the horizontal tube 42 is provided with hexagonal socket head cap screws (not shown) and multiple screw holes (not shown). The limiting tube 472 is inserted into the horizontal tube 42, and its vertical position can be adjusted using the hexagonal socket head cap screws and multiple screw holes, thereby adjusting the height of the first ridge leveling horizontal plate 45 and thus the height of the ridge.

[0045] In one embodiment, such as Figure 8 As shown, the ridge shaping component 4 also includes a connecting sheet metal part 49 for connecting a height adjustment arm, a height adjustment plate 48 nested in the connecting sheet metal part 49, and an installation tube 481, all fixedly installed on the horizontal tube 42. Understandably, the height adjustment plate 49 is nested in the rectangular hole of the connecting sheet metal part 48, and the height of the first ridge leveling horizontal plate 45 can be controlled by moving the height adjustment plate 49 up and down. A hexagonal hole is opened on the right side of the connecting sheet metal part 48, and a nut 35 is welded into the hexagonal hole. By tightening the bolt that mates with the nut 35, the displacement of the connecting sheet metal part 48 along the direction of the installation tube 491 and the displacement of the height adjustment plate 49 in the vertical direction can be limited.

[0046] In one embodiment, such as Figure 9 As shown, the implement lifting connection assembly 5 includes a lifting frame composed of a first horizontal plate 51, a second horizontal plate 52, and a vertical plate 53 connected between the first horizontal plate 51 and the second horizontal plate 52. The lifting frame is welded to the front connecting plate 17. Channel steel pulleys 54 are detachably mounted on the vertical plate 53. Understandably, the two pairs of channel steel pulleys 54 on the implement lifting connection mechanism can be installed in the slide rails of the power implement lifting device, and the overall lifting of the seeding implement can be achieved by sliding up or down in the slide rails.

[0047] In one embodiment, such as Figure 10As shown, the boot-type trencher 6 includes a trenching connecting plate 61 connected to the longitudinal beam 11 of the vehicle frame, a trenching blade 62 disposed on the front end face of the trenching connecting plate 61, trenching side plates 63 disposed on the two outer end faces of the trenching blade 62, and reinforcing ribs 64 connected to the trenching side plates 63. Understandably, the boot-type trencher 6 can efficiently and accurately complete trenching operations while ensuring soil moisture retention. Connected to the longitudinal beam 11 by the trenching connecting plate 61, the front trenching blade 62 and the two side trenching side plates 63 can compress the topsoil downwards and to both sides during operation, forming a planting trench of a certain depth. The welded structure of the trenching blade 62 and the trenching side plates 63, as well as the reinforcing ribs 64 connected to the trenching side plates 63, enhances the overall strength and stability of the trencher, effectively preventing the trenching side plates 63 from bending inwards due to stress during operation. This not only ensures that the depth and width of the furrow meet the planting requirements, but also ensures that the wet soil will not be turned over through its own weight and additional gravity, thus helping to retain soil moisture and providing good soil conditions for potato seed planting and growth. At the same time, it improves the efficiency and quality of furrowing operations.
