Description

Technical Field

[0001] The utility model relates to the field of potato planting auxiliary tools, in particular to a soil covering machine for potato planting. Background Art

[0002] In potato planting, covering the soil is a very important step. By covering the soil, the ground temperature can be increased, the evaporation of soil moisture can be reduced, and it is beneficial to drought resistance. For potatoes covered with plastic film, covering the soil on the film can allow the potato seedlings to automatically drill out of the film, which can better avoid the problems of seedling death and missing seedlings and broken ridges caused by improper film breaking and seedling release.

[0003] In the prior art, soil covering was initially done manually with a shovel, which was slow, labor-intensive, and generally uneven. Later, some specialized potato covering machines emerged. However, since the soil was generally uneven, workers still had to sit on the potato covering machines to control the direction. Part of the power of the potato covering machines was actually used to carry the workers forward, making the efficiency of these machines relatively low. Utility Model Content

[0004] In view of the above-mentioned defects, the utility model provides a soil covering machine for potato planting, which is pushed forward by humans between two ridges where potatoes are planted. Part of the driving force can be converted into a force for lifting the soil in the ditch and covering the ridges on both sides with soil, making it easier for operators to operate and achieving higher work efficiency.

[0005] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0006] A potato planting soil covering machine, comprising:

[0007] The hand push unit comprises a U-shaped chassis, a plurality of rollers are rotatably matched between two parallel sides of the chassis, and a hand push plate is arranged above the U-shaped chassis;

[0008] The soil covering unit is arranged at the front end of the hand-push unit, and includes a pair of conical gear rings respectively fixed on both sides of the front end roller of the hand-push unit, the upper end of the tooth portion of the conical gear ring is meshed with a conical gear, the upper end of the conical gear is provided with a disc portion, and the disc portion is provided with a plurality of soil covering plates arranged in a circular array. The soil covering unit also includes a pair of soil guide pipes respectively arranged in front of the two parallel sides of the U-shaped chassis, and a shovel plate for shoveling soil extends from the lower side of the lower end opening of the soil guide pipe, and a connecting plate extending toward the outer circumference of the disc portion is provided at one side of the connecting plate. The arc portion matching the outer circumference of the disc portion is provided.

[0009] Furthermore, a reinforcement plate is provided between two parallel sides of the U-shaped chassis.

[0010] Furthermore, two round rods are provided between two parallel sides of the U-shaped chassis, and the rollers are rotatably engaged with the outer circumference of the round rods.

[0011] Furthermore, the front ends of the two parallel sides of the U-shaped chassis are respectively provided with rotating holes, and the lower end of the bevel gear is provided with a rotating rod which is rotatably matched with the rotating hole.

[0012] Furthermore, a soil dividing block is provided at the lower end of the rear end of the U-shaped chassis, and its cross section is an inverted triangle.

[0013] Furthermore, an inverted V-shaped frame is provided at the upper end of the U-shaped chassis, a hand push plate is provided at the upper end of the inverted V-shaped frame, and handles are provided at both ends of the hand push plate.

[0022] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0023] like Figure 1~Figure 4The potato planting covering machine shown comprises a hand-push unit 1 and a covering unit 2.

[0024] The hand push unit 1 includes a U-shaped chassis 11, between which a reinforcement plate 12 is provided. A plurality of round rods are also provided between the two parallel sides of the U-shaped chassis 11. In the present embodiment, there are two round rods, and rollers 13 are rotatably provided on the outer circumference of the round rods. Rotating holes 14 are also provided on the front ends of the two parallel sides of the U-shaped chassis 11, respectively. A soil dividing block 15 is provided at the lower end of the rear end of the U-shaped chassis 11, and its cross section is an inverted triangle. An inverted V-shaped frame 16 is provided at the upper end of the U-shaped chassis 11, and a hand push plate 17 is provided at the upper end of the inverted V-shaped frame 16, and handles are provided at both ends of the hand push plate 17.

[0025] The soil covering unit 2 is arranged at the front end of the hand-pushing unit 1, and includes a pair of conical gear rings 21 respectively fixed to both sides of the front end roller 13 of the hand-pushing unit 1. One conical gear ring 21, the roller 13, and the other conical gear ring 21 are arranged in sequence and limited between the two parallel sides of the U-shaped chassis 11. The upper end of the tooth portion of the conical gear ring 21 is meshed with a conical gear 22. The lower end of the conical gear 22 is provided with a rotating rod 23 that is rotatably matched with the rotating hole 14. The upper end of the conical gear 22 is provided with a disc portion 24, and the disc portion 24 is provided with a plurality of soil covering plates 25 arranged in a circumferential array. The soil covering unit 2 also includes A pair of soil guide pipes 26 are respectively arranged in front of the two parallel sides of the U-shaped chassis 11 and penetrated up and down. The length direction of the soil guide pipes 26 has a predetermined angle with the horizontal plane, and the angle range is 30°-60°. Specifically, the lower sides of the two soil guide pipes 26 are provided with fixing plates 28 respectively connected to the front ends of the two parallel sides of the U-shaped chassis 11, and the lower side of the lower end opening of the soil guide pipe 26 extends with a shovel plate 27 for shoveling soil. The upper end opening of the soil guide pipe 26 is provided with a connecting plate 29 extending toward the outer peripheral side of the disc portion 24, and one side of the connecting plate 29 is provided with an arc portion matching the outer peripheral side of the disc portion 24.

[0026] The “front end” and “rear end” in this embodiment are concepts set relative to the traveling direction of the covering machine.

[0027] Working method:

[0028] The potato planting covering machine can cover soil on two rows of ridges 3 each time. First, the covering machine needs to be moved to one end of the ditch 4 between the two rows of ridges 3.

[0029] Then push the soil covering machine. Preferably, the front end of the soil covering machine can be pressed downward for a while so that the shovel plate 27 can shovel into the soil more smoothly. Then the soil continues to enter the soil guide pipe 26 through the shovel plate 27 and is finally pushed to the disc portion 24. At this time, it can be seen from the accompanying drawings that as the entire soil covering machine moves forward, when viewed from the outside, the roller 13 on the right side rotates in a clockwise direction. Then, when viewed from above, the bevel gear 22 on the right side will also rotate in a clockwise direction. Each soil covering plate 25 will disperse the soil onto the ditch 4. The same is true for the left side. Preferably, if the soil covering machine can be kept moving forward at a roughly uniform speed, the uniformity of the soil covering can be better.

[0030] Preferably, when covering the soil, the amount of soil at the position where the shovel plate 27 passes may decrease, so the setting of the covering plate 25 can make the soil at the position where the roller 13 passes be divided into two sides, so that the cross-section of the ridge 3 can be restored to an approximately V-shaped shape.

[0031] The above are only some of the embodiments listed in this application and are not intended to limit this application.
