Description

Technical Field

[0001] The utility model relates to a potato harvester with adjustable digging depth, belonging to the technical field of potato harvesters. Background Art

[0002] Potato harvester is an indispensable mechanical equipment for modern potato agricultural production. It can greatly reduce the labor intensity of potato harvesting process and improve production efficiency. At the same time, it can also increase farmers' income by improving potato harvest rate and reducing potato damage rate.

[0003] Traditional potato harvesters are not easy to adjust the digging depth. If the planting cage is high or low, the digging depth cannot be automatically adjusted according to the height of the planting cage. If the digging depth is too deep, it will cause great digging resistance, excavate more soil, make selection difficult, and greatly reduce efficiency; if the digging depth is too shallow, potatoes will be damaged and the yield will be reduced. Therefore, it is required to dig as shallow as possible without missing any soil.

[0004] In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] The utility model aims at the deficiencies in the background technology and provides a potato harvester with adjustable digging depth.

DETAILED DESCRIPTION

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0028] like Figure 1-Figure 5 As shown, the utility model provides a potato harvester with adjustable digging depth, including a soil cutting disc tool frame body 4, and a potato harvester frame body 1 is respectively installed on both sides of the rear end of the soil cutting disc tool frame body 4, and the potato harvester frame body 1 is connected to a traction machine.

[0029] An excavating device is installed at the bottom of the potato harvester frame 1, and the soil-cutting disc cutter frame body 4 includes a main beam 401. A soil-pressing roller bracket 8 is provided on the front side of the main beam 401, and a soil-pressing roller 9 is rotatably installed on the soil-pressing roller bracket 8. An adjusting rod 10 is also provided on the soil-cutting disc cutter frame body 4, and one end of the adjusting rod 10 is hinged to the main beam 401, and the other end is connected to the soil-pressing roller bracket 8. The soil-pressing roller 9 can be moved up and down by adjusting the length of the adjusting rod 10 to adapt to different depths.

[0030] A hinged portion 402 is provided on the lower side of the main beam 401, and the soil pressing roller bracket 8 includes a horizontal cross bar 802 arranged on the rear side, and the end of the horizontal cross bar 802 is hinged to the hinged portion 402, so that the soil pressing roller bracket 8 is hinged to the lower side of the main beam 401, so that the soil pressing roller 9 can swing up and down.

[0031] The front end of the adjusting rod 10 is provided with a long sliding hole 1001, and the soil pressing roller bracket 8 also includes a soil pressing roller mounting beam 803 arranged at the top, and a sliding shaft is installed at the upper end of the soil pressing roller mounting beam 803, and the sliding shaft is slidably installed in the long sliding hole 1001. Because there are potholes and uneven places in the farmland, and the traction machine will also vibrate up and down during driving, which will cause the soil pressing roller 9 to move up and down, and then cause the digging depth to fluctuate. The design of the sliding shaft being slidably installed in the long sliding hole 1001 prevents the soil pressing roller 9 from vibrating, thereby ensuring a constant digging depth and reducing the potato damage rate.

[0032] A soil cutting disc mounting frame 6 is fixed directly below both sides of the soil cutting disc cutter frame 4, and a soil cutting disc cutter 7 is rotatably mounted on the soil cutting disc mounting frame 6. The soil cutting disc cutter 7 is located on both sides of the excavating device and cuts the soil longitudinally through its blade. At the same time, the soil cutting disc cutter 7 can block the potatoes dug out by the excavating device to prevent the potatoes from leaking from both sides of the excavating device.

[0033] A mounting plate 11 is fixedly mounted on both ends of the main beam 401 , and a soil-cutting disc scraper 5 is fixed on the lower end of the mounting plate 11 . The soil-cutting disc scraper 5 scrapes away the soil on the soil-cutting disc knife 7 .

[0034] A soil pressing roller scraper 801 is installed at the lower end of the soil pressing roller mounting beam 803, and the scraper 801 scrapes the soil on the soil pressing roller.

[0035] like Figure 4 The excavating device comprises an excavating frame 2, and an excavating shovel 3 is installed at the front end of the excavating frame 2.

[0036] The specific working principle of the utility model:

[0037] During operation, the potato harvester frame 1 needs to be lowered before work to ensure that the soil pressing roller 9 is pressed on the planting cage. During the falling process, observe the position of the sliding axis of the soil pressing roller mounting beam 803 in the long sliding hole 1001 to ensure that the sliding axis is in the middle position of the long sliding hole 1001. At the same time, ensure that the digging shovel 3 is under the potato fruit, so that the soil pressing roller 9 will not vibrate, thereby ensuring a constant digging depth and reducing the potato damage rate.

[0038] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
