[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0031] The present application provides a potato digging plow, which is mainly used to solve the problem that the existing tractor-drawn potato digging plow usually includes a traction frame, a walking wheel and a soil-breaking plowshare. The soil-breaking plowshare is generally fixed to the traction frame by bolts, and the digging depth and the angle of the soil-breaking plowshare cannot be adjusted, which limits its ability to adapt to different planting depths. The following technical solutions are provided. Figure 1-Figure 5 Make a detailed description:

[0032] A potato digging plow mainly comprises a traction frame 1, two walking wheels 2, a soil-breaking plowshare 3 and an adjustment component 4, wherein: a traction rod 11 is fixed to the top of the front end of the traction frame 1, a traction head 12 is fixed to the traction rod 11, and the traction head 12 is used to connect with a tractor; support rods 13 are installed on both opposite sides of the traction frame 1, and support legs 14 are arranged on both opposite sides of the traction frame 1. The arrangement of the support legs 14 can ensure that the digging plow can be placed stably; the two walking wheels 2 are rotatably installed at the bottom ends of the two support rods 13 respectively to provide a stable walking foundation; the soil-breaking plowshare 3 is arranged at the bottom of the tail end of the traction frame 1 and is used to The adjusting component 4 is connected between the traction frame 1 and the soil-breaking plowshare 3 and is used to adjust the height and angle of the soil-breaking plowshare 3. When the device is used, the traction rod 11 of the tractor is first connected to the traction head 12 of the digging plow to ensure that the connection is firm. Then, according to the planting depth of the potatoes, the depth and angle of the soil-breaking plowshare 3 are adjusted by the adjusting component 4. After adjusting to the appropriate digging depth and angle, the tractor is started and the digging plow is pulled to work. Through the setting of the adjusting component 4, the digging plow can adapt to potatoes planted at different depths, thereby improving the adaptability to different farmland conditions.

[0033] In this example, see Figure 2-Figure 5 The number of adjustment components 4 is two and they are symmetrically arranged to ensure the balance of the soil-breaking plowshare 3. The adjustment component 4 includes a mounting block 41 fixed to the tail end of the traction frame 1. A vertical adjustment rod 42 is movably inserted on the mounting block 41. A connecting block 43 is hinged at the bottom end of the adjusting rod 42. The soil-breaking plowshare 3 is fixed to the bottom ends of the two connecting blocks 43. A positioning pin 44 is threadedly inserted on the mounting block 41. One end of the positioning pin 44 corresponds to the outer side of the adjusting rod 42. The other end of the positioning pin 44 is fixed with a hexagonal head 441. According to the potato The planting depth can be adjusted by adjusting the height of the two adjusting rods 42 and rotating the positioning pin 44 so that one end of the positioning pin 44 contacts the outer side of the adjusting rod 42, so that the adjusting rod 42 can be fixed, thereby adjusting the height of the soil-breaking plowshare 3. The setting of the hexagonal head 441 is convenient for operation with tools such as wrenches. The threaded design of the positioning pin 44 allows precise adjustment of the digging depth and improves the adjustment accuracy. A fixing part 45 is installed on the bottom end of the adjusting rod 42 and the fixing part 45 is used to fix the angle between the connecting block 43 and the adjusting rod 42.

[0034] For details, please refer to Figure 3-Figure 5The adjusting rod 42 is provided with a plurality of positioning holes 421 distributed in an array, and one end of the positioning pin 44 is movably inserted into one of the positioning holes 421. The array distribution of the positioning holes 421 provides a plurality of adjustment options, making the adjustment of the adjusting rod 42 more flexible. By inserting one end of the positioning pin 44 into one of the positioning holes 421, the stability of the adjusting rod 42 is higher. In this solution, by selecting appropriate positioning holes 421 and positioning pins 44 for cooperation, the precise adjustment of the excavation depth can be achieved. The positioning pins 44 connected by threads simplify the adjustment and fixing process of the adjusting rod 42, and improve the convenience of operation. Two positioning pins 44 are threadedly inserted on the mounting block 41, and the two positioning pins 44 are respectively inserted into two adjacent positioning holes 421. The setting of the two positioning pins 44 makes the stability of the adjusting rod 42 higher.

[0035] For further information, see Figure 3 , Figure 4 and Figure 5 The bottom end of the adjusting rod 42 is configured with a slot 422, and a hinge block 431 movably arranged inside the slot 422 is fixed on the top of the connecting block 43, and a hinge rod 432 movably penetrating the adjusting rod 42 is fixed on the hinge block 431, and a fixing hole 433 located on the same line as the hinge rod 432 is configured on the side of the hinge block 431 facing away from the hinge rod 432, and the fixing member 45 includes a fixing rod 451 movably inserted at the bottom end of the adjusting rod 42, one end of the fixing rod 451 is threadedly inserted inside the fixing hole 433, and the other end of the fixing rod 451 is fixed with a hexagonal fastening block 452. After the soil-breaking plow head 3 is adjusted to an angle, the fixing rod 451 is driven to move by rotating the hexagonal fastening block 452, so that the hexagonal fastening block 452 is tightly in contact with the adjusting rod 42, thereby fixing the angle between the connecting block 43 and the adjusting rod 42.

[0036] In order to further improve the fixing effect of the connecting block 43 and the adjusting rod 42, please refer to Figure 4 and Figure 5 A connecting rod 453 is fixed to one end of the movable adjusting rod 42 through which the hinged rod 432 passes. An arc plate 454 coaxial with the hinged rod 432 is fixed to the outer side of the adjusting rod 42. The arc plate 454 is provided with a plurality of insertion holes 455 distributed in an array. A plug rod 456 is threadedly passed through the connecting rod 453. One end of the plug rod 456 is movably inserted into one of the insertion holes 455. After the angle of the soil-breaking plowshare 3 is adjusted, the plug rod 456 is rotated so that one end of the plug rod 456 is inserted into the corresponding insertion hole 455. This can provide an additional fixing effect, and the angle of the connecting block 43 is more stable, thereby making the soil-breaking plowshare 3 more stable when working.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
