[0020] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] Reference Figure 1 to Figure 11 A potato sowing device with an adjustable crawler 4 chassis is proposed, comprising: a frame 1; a sowing mechanism 2 is arranged on the frame 1; there are two adjusting frames 3, which are slidably arranged on the frame 1, and the crawler 4 is sleeved on the adjusting frames 3, and the two adjusting frames 3 are used to support the frame 1. After the two adjusting frames 3 slide, they move closer to or away from each other; there are two first telescopic members 5, which are arranged on the frame 1, and the two first telescopic members 5 independently drive one adjusting frame 3 to rise and fall.

[0022] In this embodiment, the two adjustment frames 3 are slidably arranged to be close to or far from each other, and the spacing between the crawlers 4 can be flexibly adjusted according to different terrains and operating requirements, thereby improving the stability and passability of the chassis on complex terrains. The first telescopic member 5 can independently control the lifting and lowering of each adjustment frame 3, even in mountainous areas, with a certain inclination angle, the frame 1 can adapt to the undulating ground in mountainous and hilly areas, and maintain a horizontal state, thereby ensuring the normal operation and sowing accuracy of the sowing mechanism 2, increasing the adaptability of the crawler 4 chassis, so that it can stably travel in various complex mountainous and hilly terrains, and reducing the bumps and tilts caused by uneven terrain. Moreover, the device can effectively avoid problems such as uneven sowing and inconsistent depth caused by the tilt of the chassis, and improve the quality and emergence rate of potato sowing. The flexible adjustment function enables the device to maintain good operating performance under different slopes and terrain conditions, thereby improving work efficiency and scope of application.

[0023] As a further technical solution, the adjustment frame 3 includes: a main support rod 6 is slidably set on the frame 1; a support seat 7 is lifted and lowered on the main support rod 6; there are several lower support wheels 8, which are rotatably set on the support seat 7; a tensioning seat 9 is slidably set on one side of the support seat 7, and a tensioning wheel 10 is rotatably set on the tensioning seat 9; a driving wheel 11 is set on the frame 1, and the driving wheel 11, the lower support wheel 8 and the tensioning wheel 10 are all in contact with the inner wall of the track 4, and the driving wheel 11 is used to drive the track 4 to rotate.

[0024] In this embodiment, the main support rod 6 is slidably arranged to facilitate adjustment of the position of the entire adjustment frame 3, thereby changing the spacing between the tracks 4 to adapt to different terrains. The lifting and lowering arrangement of the support seat 7 can further fine-tune the height of the chassis and enhance the adaptability to complex terrain. The multiple lower support wheels 8 are evenly distributed, which can support the track 4 more stably, disperse the pressure, and reduce the wear of the track 4. The setting of the tensioning seat 9 and the tensioning wheel 10 can adjust the tension of the track 4 to ensure that the track 4 maintains a good transmission effect during operation and reduces slippage. The effective contact between the driving wheel 11, the lower support wheel 8 and the tensioning wheel 10 and the inner wall of the track 4 forms a stable transmission and support structure, which ensures the normal operation and power transmission of the chassis of the track 4 and improves the reliability and work efficiency of the device.

[0025] As a further technical solution, the tensioning seat 9 has a first screw hole 12, the support seat 7 has a plurality of second screw holes 13, and also includes: a first screw 14 is rotatably set on the support seat 7, and the first screw 14 is threadedly engaged with the first screw hole 12; there are a plurality of first bevel gears 15, which are set on the first screw 14; a second screw 16 is rotatably set on the support seat 7, and the second screw 16 is threadedly engaged with the second screw hole 13, and the second screw 16 is used to drive the support seat 7 to rise and fall; a second bevel gear 17 is set on the second screw 16, and the first bevel gear 15 is meshed with the second bevel gear 17.

[0026] In this embodiment, the position of the tensioning seat 9 is precisely adjusted by the threaded cooperation between the first screw 14 and the first screw hole 12, and the meshing transmission between the first bevel gear 15 and the second bevel gear 17, so as to effectively control the tension of the crawler 4 and ensure the stability and reliability of the operation of the crawler 4. The threaded cooperation between the second screw 16 and the second screw hole 13 makes the lifting and lowering adjustment of the support seat 7 more accurate and stable, and can accurately adjust the height of the chassis according to the terrain changes. The transmission mode of the bevel gear has a compact structure and high transmission efficiency. It can effectively transmit the rotational power and realize the motion conversion in different directions, meeting the requirements of tensioning and lifting adjustment. This combined adjustment structure of the screw and the bevel gear is simple to operate and easy to control, reduces the complex mechanical structure, reduces the probability of failure, and improves the maintainability of the device. Accurate tension adjustment and height lifting adjustment help to improve the adaptability and stability of the entire chassis, thereby ensuring the operation quality and efficiency of the potato sowing device in mountainous and hilly areas.

The first gear 22 on the two rotating shafts 21 drives the conveyor chain 23 to rotate in a circle, and the transmission is smooth and reliable, ensuring the continuity and accuracy of the feeding process. The feed plate 24 is arranged at intervals in an array, which can accurately control the number of potato tubers sent out each time, thereby realizing precise sowing, improving the emergence rate and planting quality. This sowing mechanism 2 has a compact structure, occupies a small space, cooperates well with the adjustable crawler 4 chassis, and is suitable for the complex working environment in mountainous and hilly areas.

[0029] As a further technical solution, it also includes: a trenching seat 25 is arranged on the frame 1; there are two adjusting rods 26, one end of each of the two adjusting rods 26 is hinged to the trenching seat 25; a trenching member 27 is hinged to the other ends of the two adjusting rods 26, and the trenching seat 25, the two adjusting rods 26 and the trenching member 27 form a parallelogram structure; a connecting block 28 is arranged on an adjusting rod 26; a second telescopic member 29 is arranged on the frame 1, the second telescopic member 29 is hinged to the connecting block 28, and the second telescopic member 29 is used to drive the adjusting rod 26 to rotate, and after the adjusting rod 26 rotates, the trenching member 27 extends into or leaves the ground.

[0030] In this embodiment, the parallelogram structure formed by the ditching seat 25, the adjusting rod 26, and the ditching member 27 enables the ditching member 27 to maintain a relatively stable posture during the lifting process, ensuring that the depth and shape of the ditching are relatively uniform. The second telescopic member 29 controls the ditching member 27 to penetrate or leave the ground by driving the adjusting rod 26 to rotate. The operation is simple and the control is precise. The ditching depth can be flexibly adjusted according to different soil conditions and sowing requirements. This adjustable ditching structure can adapt to the diverse terrain and soil hardness in mountainous and hilly areas, and improve the adaptability and quality of ditching operations. The coordination of the parallelogram structure and the telescopic member effectively reduces the vibration and impact during the ditching process and prolongs the service life of the equipment. It can achieve stable and controllable ditching operations in complex mountainous and hilly terrains, create good conditions for subsequent potato sowing, and improve sowing effects and crop growth environments.

[0031] As a further technical solution, it also includes: a ridging frame 30 is rotatably set on the frame 1, the ridging frame 30 is located behind the furrowing member 27, and after the ridging frame 30 rotates, it enters or leaves the ground; the rotary tillage shaft 31 is rotatably set in the ridging frame 30, and the rotary tillage shaft 31 is used to crush the soil; the ridging board 32 has a plurality of blocks, which are obliquely set in the ridging frame 30, and the ridging board 32 is located behind the rotary tillage shaft 31, and the ridging board 32 is used to shape the soil crushed by the rotary tillage shaft 31 into ridges.

[0032] In this embodiment, the ridging frame 30 is rotatably arranged on the frame 1, and can flexibly enter or leave the ground as needed, so as to facilitate ridging operations at different operation stages or avoid unnecessary interference. The rotary tillage shaft 31 can crush the soil to make the soil looser, which is conducive to the growth of seeds and drainage, moisture conservation and field management as a further technical solution. This ridging structure cooperates with the ditching operation, and can complete the continuous processes of ditching, crushing the soil and ridging in one operation, thereby improving the operation efficiency and reducing the number of operations and costs. It is adapted to the complex soil conditions in mountainous and hilly areas, and improves the soil structure by crushing and shaping the soil, thereby improving the utilization rate of land and the adaptability of potato planting.

[0033] As a further technical solution, the bottom of the storage hopper 18 is conical.

[0034] In this embodiment, the bottom of the storage hopper 18 is tapered, which is conducive to the concentration of potato tubers to the matching holes 19, ensuring smooth material discharge and reducing the accumulation and blockage of materials at the bottom of the storage hopper 18. The tapered design can improve the discharge efficiency of the material in the storage hopper 18, making the feeding process more continuous and stable, and helping to achieve uniform sowing. It is convenient to better control the flow speed and flow rate of the material, so as to more accurately cooperate with the feeding plate 24 to transport potato tubers. The residual material in the storage hopper 18 is reduced, the waste of seeds is reduced, and the planting cost is saved. This design makes the storage hopper 18 more compact and occupies less space, while enhancing the stability of the entire sowing device.

[0038] In this embodiment, the film covering shaft 34 can perform film covering operation in time after the field ridge is formed, effectively maintain the temperature and humidity of the soil, and create favorable environmental conditions for the growth of potatoes. It is helpful to reduce the evaporation of soil moisture and improve the water utilization rate, which is of great significance to the growth of potatoes, especially in arid mountainous and hilly areas.
