Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a potato harvester with adjustable depth. Background Technology
[0002] In modern agricultural production, potatoes are an important food crop, and their harvesting efficiency and quality directly affect the economic benefits and crop quality of agricultural production. With the continuous improvement of agricultural mechanization, potato harvesters have gradually become indispensable equipment in agricultural production. However, in practical applications, existing potato harvesters still face many challenges, especially in adapting to different soil conditions and harvesting depths.
[0003] Currently, most potato harvesters on the market use a fixed shovel and conveyor design. While this design can meet basic harvesting needs, it has poor adaptability when facing soils of varying depths and complex terrains. For example, during the harvesting of potatoes in soft soil or shallow planting, the fixed shovel depth may lead to over-digging or damage of the potatoes, while when harvesting potatoes planted in deeper soil, the fixed shovel cannot effectively penetrate the soil, affecting harvesting efficiency.

[0017] By adopting the above technical solution, the angle adjustment function of the loosening shovel is added, which can adjust the angle of the loosening shovel according to soil conditions and potato planting status, further optimizing the loosening effect and reducing damage to potatoes.
[0018] Furthermore, the adjustment mechanism includes a swing rod extending radially along the rotation axis, a horizontal plate fixing the swing rod at a preset position, the horizontal plate being fixedly mounted on the upright, and a screw being rotatably mounted on the swing rod, the screw passing through the horizontal plate and being fixed to the horizontal plate by a nut.

[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0039] This embodiment relates to a potato harvester with adjustable depth. In terms of overall structure, as follows... Figure 1 As shown, its components include a frame 1, a conveyor belt 2, a loosening shovel 3, a lifting mechanism 4, and wheels 5.
[0040] The machine frame 1 has a vertical frame 6 at the tail end and a mounting frame 7 at the head end. The loosening shovel 3 is set at the bottom of the mounting frame 7 to loosen the soil. The lifting mechanism 4 is set on the mounting frame 7 and drives the loosening shovel 3 to lift. The two ends of the conveyor belt 2 are located at the head of the machine frame 1 and the top of the vertical frame 6 to transport the potatoes shoveled by the loosening shovel 3. The wheels 5 are installed at the bottom of the machine frame 1.
[0041] It is worth mentioning that the upright frame 6 ensures that the potatoes can be tilted and lifted. During the lifting process, excess soil can be removed and fall through the gaps in the conveyor belt 2. It also ensures that the potatoes are transported to the next stage of equipment for further processing. The mounting frame 7 is used to install the lifting mechanism 4, ensuring that the loosening shovel 3 is located at the front end of the conveyor belt 2. The loosening shovel 3 moves up and down under the drive of the lifting mechanism 4, ensuring that the loosening shovel 3 can loosen the soil at different depths. The wheels 5 facilitate the movement of the frame 1 in the soil.
[0042] Based on the above overall introduction, this embodiment presents an exemplary structure of a potato harvester with adjustable depth, such as... Figure 2 As shown, a conveyor shovel 8 is installed between the conveyor belt 2 and the loosening shovel 3. The conveyor shovel 8 is rotatably mounted at the front end of the frame 1. Through holes 9 are respectively opened on the frame 1 and the conveyor shovel 8, and pins 10 are inserted into the through holes 9. It should be noted that multiple through holes 9 are opened on the frame 1. When the pins 10 are inserted into the through holes 9 of the frame 1 and the conveyor shovel 8, the conveyor shovel 8 can be fixed. Different through holes 9 on the frame 1 can fix the conveyor shovel 8 to different positions, thereby shoveling soil at different depths, thus more effectively protecting the potatoes from being damaged. In other words, after the loosening shovel 3 loosens the soil, the conveyor shovel 8 shovels the potatoes out of the soil and transfers them to the conveyor belt 2, thus completing the potato harvest.
[0043] As a preferred embodiment, it is still as follows Figure 2 As shown, in this embodiment, the conveying shovel 8 is provided with a fixed shaft 11, and the frame 1 has a circular hole 12 for inserting the fixed shaft 11. Multiple through holes 9 are formed on the frame 1 along the circumference of the circular hole 12. Specifically, the purpose of having the through holes 9 along the circumference of the circular hole 12 is to ensure that the through holes 9 on the conveying shovel 8 coincide with each through hole 9 on the frame 1, facilitating the engagement of the pin 10. The fixed shaft 11 can rotate within the circular hole 12, ensuring that the bottom of the conveying shovel 8 can rotate to different positions. Combined with the lifting and lowering of the loosening shovel 3, this allows for better adaptation to soil depths.
[0044] As a preferred option, such as Figure 3As shown, the lifting mechanism 4 in this embodiment includes pin holes 401 on the mounting frame 7, a vertical rod 402 installed at the pin holes 401, and bolts 403 that fix the vertical rod 402 at the pin holes 401. The loosening shovel 3 is installed at the bottom of the vertical rod 402. It should be noted that the vertical rod 402 has multiple pin holes 401 arranged vertically, which are the same as those on the mounting frame 7. The vertical rod 402 is lifted and lowered by inserting bolts 403 into different pin holes 401. The bolts 403 pass through the pin holes 401 on the mounting frame 7 and the vertical rod 402 respectively for fixation. When the vertical rod 402 is lifted and lowered, it can drive the loosening shovel 3 to lift and lower. The bolts 403 can fix the vertical rod 402 in the adjusted position. The mounting frame 7 has pin holes 401 at both the top and bottom ends. This arrangement can improve the strength of the vertical rod 402 on the mounting frame 7.
[0045] As a preferred embodiment, it is still as follows Figure 3 As shown, in this embodiment, multiple sets of uprights 402 are provided on the mounting frame 7. A rotating shaft 404 is rotatably mounted at the bottom of the uprights 402, and the loosening shovel 3 is fixedly mounted on the rotating shaft 404. An adjustment mechanism 13 for adjusting the angle of the loosening shovel 3 is provided on the rotating shaft 404. It should be noted that the arrangement of multiple sets of uprights 402 can ensure the strength of the loosening shovel 3 on the mounting frame 7, the arrangement of the rotating shaft 404 can adjust the angle of the loosening shovel 3, and the adjustment mechanism 13 can fix the loosening shovel 3 in the adjusted position. This arrangement can ensure that potatoes are shoveled out when loosening the soil, thereby improving the harvest quality.
[0046] As a preferred option, such as Figure 4 As shown, the adjustment mechanism 13 of this embodiment includes a swing rod 1301 extending radially along the rotation axis 404, and a horizontal plate 1302 that fixes the swing rod 1301 at a preset position. The horizontal plate 1302 is fixedly mounted on the upright 402. A screw 1304 is rotatably mounted on the swing rod 1301. The screw 1304 passes through the horizontal plate 1302 and is fixed to the horizontal plate 1302 by a nut 1305. Specifically, the swing rod 1301 and the rotating shaft 404 are fixedly connected. The swing rod 1301 is fixed to the horizontal plate 1302 by the screw 1304. This arrangement ensures that the swing rod 1301 can be fixed after the position is adjusted. A strip groove 1303 can be opened on the horizontal plate 1302. The screw 1304 can pass through the strip groove 1303 and slide inside it. The nut 1305 rotates on the screw 1304, thereby driving the swing rod 1301 to swing. Nuts 1305 are provided on both the upper and lower sides of the horizontal plate 1302 to fix the screw 1304 to the horizontal plate 1302. This arrangement ensures that the loosening shovel 3 can be fixed after the adjustment.
[0047] The potato harvester with adjustable depth in this embodiment realizes the lifting and position adjustment functions of the loosening shovel 3 and the conveying shovel 8, which can adapt to soil conditions at different depths and significantly improve the harvesting efficiency and integrity of potatoes. Through the multi-level adjustment structure, the flexibility and versatility of the equipment are enhanced, enabling it to better cope with complex farmland environments. The angle adjustment function of the loosening shovel 3 is optimized, further improving the loosening effect and reducing damage to potatoes during the harvesting process. The use of a stable adjustment mechanism 13 and a fixed structure improves the reliability and service life of the equipment.
[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
