Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-2 As shown, a chassis driving device of a potato harvester with adjustable ridge spacing comprises: a harvester crawler 1, a support frame 6 and a chassis adjusting rod 9, wherein a crawler frame 2 is provided inside the harvester crawler 1, and the harvester crawler 1 can be supported by the crawler frame 2, and a hydraulic driving mechanism 3 is installed on the upper part of the crawler frame 2, and the hydraulic driving mechanism 3 can drive a driving wheel 4 to rotate, and a driving wheel 4 is connected to one side of the hydraulic driving mechanism 3, and a driven wheel 5 is connected to the other side of the driving wheel 4, so that the driving wheel 4 and the driven wheel 5 can rotate on the inside, and a support frame 6 is installed on the outside of the crawler frame 2, and a first sliding guide rail 7 is installed inside the support frame 6, and the first sliding guide rail 7 can be fixed to the side of the crawler frame 2 by the support frame 6. An upper telescopic cylinder 8 is installed on the upper end of the support frame 6 and the first sliding guide rail 7, and the first sliding guide rail 7 can be moved by the upper telescopic cylinder 8. A chassis adjusting rod 9 is installed on the inner side of the crawler bracket 2, and a second sliding guide rail 10 is installed inside the chassis adjusting rod 9. The second sliding guide rail 10 can be fixed to the side of the crawler bracket 2 by means of the chassis adjusting rod 9. A lower telescopic cylinder 11 is installed on the lower end of the chassis adjusting rod 9 and the second sliding guide rail 10, and the second sliding guide rail 10 can be moved by the lower telescopic cylinder 11. A telescopic support rod 12 is installed on one side of the support frame 6 and the chassis adjusting rod 9, and the entire crawler can be supported by the telescopic support rod 12. A chassis connecting frame 13 is installed on the upper part of the support frame 6 and the chassis adjusting rod 9.

[0021] Furthermore, the support frame 6 and the chassis adjusting rod 9 are fixedly connected to the track frame 2, the first sliding guide rail 7 and the second sliding guide rail 10 are fixedly connected to the track frame 2, and the support frame 6, the chassis adjusting rod 9 and the sliding guide rail are arranged on the side of the track frame 2 to save space.

[0022] Furthermore, the support frame 6 and the chassis adjusting rod 9 are in an embedded sliding connection with the first sliding guide rail 7 and the second sliding guide rail 10, and the height of the support frame 6 is greater than the height of the chassis adjusting rod 9, which can improve the lifting operation of the harvester's digging shovel and at the same time lower the center of gravity to prevent the machine from tipping over in hilly areas.

[0023] Furthermore, auxiliary wheels 14 are connected to the inner sides of the driving wheel 4 and the driven wheel 5 , so that the driving wheel 4 and the driven wheel 5 can rotate inside the harvester track 1 .

[0024] Furthermore, the telescopic support rod 12 is a hydraulic telescopic rod, and a fixing block is installed at the lower part of the telescopic support rod 12. The harvester as a whole can be supported by lifting and lowering the telescopic support rod 12.

[0025] Furthermore, one end of the upper telescopic cylinder 8 and the lower telescopic cylinder 11 are connected to the sliding guide rail, and the other end is connected to the fixed block. Through the telescopic movement of the upper telescopic cylinder 8 and the lower telescopic cylinder 11, the track track can be adjusted.

[0026] Furthermore, the driving wheel 4 and the driven wheel 5 are rotatably connected to the track frame 2 via a connecting shaft, so that the driving wheel 4 and the driven wheel 5 can rotate along the track frame 2.

[0027] According to the principle of the utility model, the harvester crawler 1 can be supported by the crawler bracket 2. Since the height of the support frame 6 is greater than the height of the chassis adjusting rod 9, the lifting operation of the harvester shovel can be improved, and the center of gravity can be lowered to prevent the machine from tipping over in hilly areas. The support frame 6 is fixed to the outside of the crawler bracket 2 to facilitate the arrangement of the engine above the machine. The first sliding guide rail 7 and the second sliding guide rail 10 are fixed to the inside of the crawler bracket 2 to save space. The wheelbase between the harvester crawler 1 is adjustable. By extending and retracting the upper telescopic cylinder 8 and the lower telescopic cylinder 11, different crawler wheelbases can be adjusted to adapt to different potato planting patterns.

[0028] Before adjustment, the harvester is supported as a whole by the telescopic support rod 12. The telescopic support rod 12 is connected to the main frame of the machine. The telescopic support rod 12 is on one side of the machine and can lift up the supported crawler. After the supported crawler leaves the ground, the upper telescopic cylinder 8 and the lower telescopic cylinder 11 push the first sliding guide rail 7 and the second sliding guide rail 10 to move outward. The first sliding guide rail 7 and the second sliding guide rail 10 both play a guiding and supporting role, thereby increasing the wheelbase of the crawler to adapt to the potato operation mode with a wide ridge spacing. Similarly, the upper telescopic cylinder 8 and the lower telescopic cylinder 11 contract to move the first sliding guide rail 7 and the second sliding guide rail 10 inward, thereby reducing the wheelbase between the harvester crawler 1, so that the first sliding guide rail 7 and the second sliding guide rail 10 can complete both sliding and supporting functions, thereby reducing the wheelbase of the crawler to adapt to the potato operation mode with a narrow ridge spacing, and thus being suitable for potato harvesting in different planting modes.
