[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-6 As shown, a uniform seeding device for a potato planter includes two tillage planters 1. The rear of the two tillage planters 1 is fixedly connected to a main connecting frame 2 by a hoop. Two side plates 6 are installed on the left and right sides of the top of the main connecting frame 2 by screw threads. A winding assembly 3 is installed between the opposite surfaces of the two side plates 6. Two unwinding assemblies 4 are symmetrically installed on the rear sides of the main connecting frame 2 away from the middle along its length direction. Two soil-shoveling assemblies 5 are respectively installed on the front sides of the left and right ends of the main connecting frame 2 along its width direction.

[0026] In practical use, this new design uses two land clearing and planting machines 1 to clear the land in double rows and plant potato seeds. The unwinding assembly 4 unwinds the plastic film installed on the winding assembly 3. In this way, the plastic film on the winding assembly 3 is laid on the sown land during the sowing process of the two land clearing and planting machines 1, so that the two key processes of sowing and mulching can be completed in a continuous and efficient manner, which greatly improves the overall efficiency and quality of potato planting. The soil shoveling assembly 5 is set to press the unwound plastic film in place, which effectively avoids the plastic film from shifting or being lifted due to wind, human touch or other factors.

[0027] Specifically, the winding assembly 3 includes a hinge seat 31 and a connecting seat 34. The hinge seat 31 and the connecting seat 34 are symmetrically and rotatably mounted on the opposite surfaces of the two side plates 6. The opposite surfaces and tops of the hinge seat 31 and the connecting seat 34 are open. A hinge block 32 is rotatably mounted on the inner surface of the hinge seat 31. A connecting rod 33 is fixedly mounted on one end of the hinge block 32 near the connecting seat 34.

[0028] A limiting block 35 adapted to the inner surface of the connecting seat 34 is fixedly installed at the end of the connecting rod 33 away from the hinge block 32. A through threaded hole 36 is opened at one end of the connecting seat 34 and the limiting block 35 along its height direction. A screw 37 is threadedly installed on the inner surface of the threaded hole 36.

[0029] Remove the screw 37 from the connecting seat 34, rotate the connecting rod 33 upward to release the limiting effect of the limiting block 35 and the connecting seat 34, so that the plastic film roll is inserted into the connecting rod 33. When unwinding, the plastic film is pressed onto the ground by the two unwinding components 4. As the two tillage seeders 1 move forward, the plastic film roll inserted into the connecting rod 33 rotates and unwinds.

[0030] Specifically, the unwinding assembly 4 includes two L-shaped rods 41, which are symmetrically installed at the rear end of the main connecting frame 2 away from the middle in the length direction. Two fixing discs 42 are fixedly installed on the middle part of the outer surface of the two L-shaped rods 41 along their height direction.

[0031] Two slip rings 43 are slidably mounted on the vertical outer surface of the two L-shaped rods 41 respectively. Two springs 44 are respectively sleeved on the lower side of the vertical outer surface of the two L-shaped rods 41. Two limiting discs 421 are respectively fixedly mounted on the bottom of the two L-shaped rods 41 in the vertical direction. The two ends of the two springs 44 are respectively held between the two fixed discs 42 and the two slip rings 43.

[0032] Two connecting blocks 45 are fixedly installed on the bottom end of the two slip rings 43, which are close to each other. Two shafts 451 are fixedly installed on the bottom end of the two connecting blocks 45, which are close to each other. Two pressure rollers 46 are rotatably installed on the outer surface of the two shafts 451.

[0033] After the plastic film roll on the outer surface of the connecting rod 33 is laid on the ground, the two pressure rollers 46 are respectively pressed on both sides of the plastic film laid on the ground. As the two tillage seeders 1 move forward, the two pressure rollers 46 press down on the plastic film on the ground, so that the plastic film roll on the connecting rod 33 is pulled to achieve unwinding.

[0034] Because the cultivated ground is uneven, the two pressure rollers 46 slide along the vertical direction of the L-shaped rod 41 through the two slip rings 43. In this way, the two pressure rollers 46 can be raised and lowered according to the height of the road surface during the driving process. During the raising and lowering process, the tension of the spring 44 pushes the slip ring 43 to return to its original position.

[0035] Specifically, the two soil-shoveling components 5 include two connecting arms 51, which are symmetrically installed at both ends of the main connecting frame 2 in the width direction. Two base plates 52 are fixedly installed at the bottom ends of the two connecting arms 51 respectively, and two mounting brackets 53 are fixedly installed at the bottom ends of the two base plates 52 respectively. Two plow blades 54 are respectively installed on the end faces of the two mounting brackets 53 that are close to each other by bolt threads.

[0036] As the two tillage and seeding machines 1 move, they drive the two plow blades 54 on the underside of the two base plates 52 to scoop up the soil on the ground. The scooped soil splashes along the slope of the plow blades 54 onto the unrolled plastic film, pressing the plastic film in place.

[0037] It should be noted that the two land clearing and planting machines 1 used in this utility model are potato planters with authorization announcement number: 201020249499.7. Their specific working principles are all existing technologies and will not be described in this solution.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
