DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0031] like Figure 1-Figure 9 As shown, a sweet potato ridging machine comprises a frame 1 and a traction frame 2 welded to the front end of the frame 1, a ridging structure is arranged at the bottom of the frame 1, the ridging structure comprises fixed blocks 8 fixed to both sides of the bottom of the frame 1, and a shaft 5 rotatably connected between the two fixed blocks 8, two groups of symmetrically distributed ridging members are arranged on the shaft 5, and each group of ridging members comprises a fixed cylinder 3 fixed to the shaft 5, and a movable cylinder 4 slidably sleeved on the outside of the shaft 5;

[0032] An adjusting mechanism 7 for adjusting the distance between the two moving cylinders 4 is also provided on the shaft 5, and the adjusting mechanism 7 includes a bidirectional threaded rod 71 rotatably installed between the two fixed blocks 8, and a sleeve 72 fixed at one end inside the two moving cylinders 4, and a screw seat 73 sleeved on the bidirectional threaded rod 71 is installed in each of the two sleeves 72. The shaft 5 has a cavity inside for the bidirectional threaded rod 71 to pass through, and grooves for the screw seat 73 to move are provided on both sides of the shaft 5; one end of the bidirectional threaded rod 71 extends to the outside of the fixed block 8, and an adjusting disk 74 is installed.

[0033] When performing ridge forming operation on a sweet potato planting field, the frame 1 can be connected to a traction device (common agricultural machinery, such as a tractor) through a traction frame 2, and then the fixed cylinder 3 and the movable cylinder 4 are driven to move along the sweet potato planting field under the action of the shaft 5 through the traction of the traction device, and the sweet potato planting field is divided into ridges through the cooperation of the two sets of fixed cylinders 3 and movable cylinders 4 to complete the ridge forming operation;

[0034] During the ridging operation, the distance between the two movable cylinders 4 can be adjusted according to the ridging requirements, and then the distance between the movable cylinder 4 and the fixed cylinder 3 can be adjusted to adjust the ridging width, and the specific adjustment steps are as follows:

[0035] By rotating the bidirectional threaded rod 71 through the adjusting disk 74, the bidirectional threaded rod 71 drives the two screw seats 73 to move relative to each other along their axial directions. Then the screw seat 73 drives the movable cylinder 4 to move relative to each other along the shaft 5 through the sleeve 72, thereby adjusting the distance between the two movable cylinders 4, thereby meeting the requirements of different ridge forming widths, improving the application range of the ridging machine, and facilitating its use in sweet potato cultivation.

[0036] Furthermore, if Figure 1-Figure 5 As shown, telescopic covers 75 are connected between both sides of the screw seat 73 and the slot, and the telescopic covers 75 are used to cover the slot.

[0037] During the use of the ridger, the telescopic cover 75 covers the slot, which can prevent soil from entering the shaft rod 5 to facilitate the rotation of the bidirectional threaded rod 71. During the adjustment of the moving cylinder 4, the telescopic cover 75 can be extended and retracted accordingly, thereby ensuring effective covering of the slot and preventing soil from entering the interior of the shaft rod 5.

[0038] Furthermore, if Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the adjustment mechanism 7 also includes a limit assembly, and the limit assembly includes a limit plate 9 installed on the side wall of one of the fixed blocks 8, and a plurality of limit holes 10 distributed in a ring array are opened on the limit plate 9, and two limit rods 12 are inserted on the adjustment plate 74, and one end of the two limit rods 12 is respectively inserted into the corresponding limit holes 10, and the other ends of the two limit rods 12 are commonly connected to a handle 11.

[0039] When adjusting the movable cylinder 4, the limit rod 12 can be pulled out of the limit hole 10 on the limit plate 9 through the handle 11, and then the bidirectional threaded rod 71 can be rotated through the adjusting disk 74 to achieve the adjustment of the movable cylinder 4. After the adjustment of the movable cylinder 4 is completed, the limit rod 12 can be inserted into the corresponding limit hole 10 on the limit plate 9 through the handle 11 to limit the adjustment plate 74 and the limit plate 9, thereby preventing the bidirectional threaded rod 71 from rotating, so as to achieve the stability of the movable cylinder 4 after adjustment, which is beneficial to the stable operation of the ridging machine.

[0040] In addition, in one embodiment, if Figure 1-Figure 3 as well as Figure 5 and Figure 6As shown, a ditch clearing mechanism 6 is also provided at the rear end of the frame 1, and the ditch clearing mechanism 6 includes a connecting rod 61 fixed at the rear end of the frame 1, a bracket 62 is welded to one end of the connecting rod 61 away from the frame 1, and a shovel piece 63 is welded to the front side of the bracket 62.

[0041] During the ridge forming operation, the ditch clearing mechanism 6 moves along the ditch formed between the two movable cylinders 4 under the drive of the frame 1. At this time, the shovel member 63 shovels up the scattered soil in the ditch, and as the frame 1 moves, the soil is shoveled out of the ditch, thereby clearing the ditch without the need for subsequent manual ditch clearing, thereby greatly reducing the labor intensity of the ridge forming operation and improving the efficiency of the ridge forming operation.

[0042] Furthermore, if Figure 1-Figure 3 as well as Figure 5 and Figure 6 As shown, the ditch cleaning mechanism 6 further includes two scraping plates 65 arranged at the rear side of the bracket 62, and the two scraping plates 65 are distributed in an eight-shaped shape.

[0043] During the ditch clearing process, two scraper plates 65 distributed in an eight-shaped shape will scrape the soil missed by the two sides of the shovel piece 63, so as to effectively clean the ditch and avoid residual soil in the ditch, thereby improving the ditch clearing effect and further facilitating the ridge formation of the sweet potato planting field.

[0044] Furthermore, if Figure 1-Figure 3 as well as Figure 5 , Figure 6 and Fig. 9 As shown, a connecting frame 64 is welded to the rear side of the bracket 62, and an adjusting screw 66 is rotatably installed between the vertical portion of the connecting frame 64 and the bracket 62, a moving seat is sleeved on the adjusting screw 66, and telescopic connecting rods 67 are connected to both sides of the moving seat, the bottom ends of the two telescopic connecting rods 67 are connected to support rods 68, and sliders 610 are installed at the bottom ends of the two support rods 68, and the tops of the two scraper plates 65 are provided with sliding grooves 69 for the two sliders 610 to slide respectively, and one end of the two scraper plates 65 is hinged to the bracket 62, and a knob is installed on one end of the adjusting screw 66 relative to the connecting frame 64.

[0045] When the distance between the two moving cylinders 4 is adjusted, the adjusting screw 66 can be rotated by the knob, so that the adjusting screw 66 drives the moving seat to move along its axial direction, and then the moving seat drives the support rod 68 to move through the telescopic connecting rod 67. At this time, the slider 610 at the bottom end of the support rod 68 slides in the slide groove 69 at the top of the scraper plate 65, and as the support rod 68 moves, the telescopic connecting rod 67 can be extended and retracted accordingly, thereby driving the two scraper plates 65 to open or close, thereby realizing the opening and closing adjustment of the two scraper plates 65, so that the scraper plates 65 can adapt to the width of the ditch formed after the distance between the two moving cylinders 4 is adjusted, thereby ensuring the effective cleaning of the ditch by the scraper plate 65, further improving the ditch cleaning effect, and facilitating the ridge formation of the sweet potato planting field.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
