[0019] ​The utility model is further described below with reference to the drawings and specific embodiments, but is not used to limit the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.

[0020] Embodiment

[0021] The soil leveling device for land consolidation described in the embodiment comprises a mounting frame 1, a traction frame connected with a tractor is arranged on the mounting frame 1, the traction frame comprises two traction arms 5 distributed in front and back, and the traction ends of the two traction arms 5 are connected with a same connector 6 connected with the tractor. Figures 1 to 4 When used, the two traction arms 5 help to improve the stability of the structure, and the traction arm 5 is a prior art and is mainly used to connect with the traction end of the tractor.

[0022] The mounting frame 1 is in a 'door' type structure, a rotating shaft 10 freely rotatable is installed in the mounting frame 1, mounting holes are formed on the inner side walls in front and back of the mounting frame 1, and the front and back ends of the rotating shaft 10 are independently and freely rotatably arranged in the mounting holes.

[0023] A plurality of scrapers 8 distributed along the circumference of the rotating shaft 10 are fixed on the rotating shaft 10, the scrapers 8 are four, and the four scrapers 8 are distributed on the outer side wall of the rotating shaft 10 at equal intervals; the scrapers 8 can also be three. Each scraper 8 is distributed along the length direction of the rotating shaft 10.

[0024] As shown in Figure 1 The inner top of the mounting frame 1 is installed with a blocking plate 4 used for abutting against any one of the scrapers 8 and limiting the rotation of the rotating shaft 10, and the blocking plate 4 is made of an elastic material. The whole part constitutes a blocking assembly used for limiting the rotation of the rotating shaft 10. When used, since the blocking plate 4 appears in the rotation path of the scraper 8, the rotating shaft 10 cannot rotate due to the blocking of the blocking plate 4 to one of the scrapers 8.

[0025] As shown in Figure 1As shown, in use, the tractor moves forward through the traction arm 5 to move the traction frame 1, the blade 8 is in contact with the ground, and the soil is leveled, but as the movement, the soil accumulated in front of the blade 8 in working at this time gradually increases, and the resistance is generated in the opposite direction of the movement of the blade 8, when reaching a point, the force breaks through the restriction of the blocking plate 4 to the upper blade 8, the rotating shaft 10 rotates a quarter of a circle, the blade 8 originally working rotates to the right side of the rotating shaft 10, the blade 8 on the left side rotates to the lower side of the rotating shaft 10 to replace the leveling work, and the blade 8 originally on the right side rotates to the upper side of the rotating shaft 10 and is blocked by the blocking plate 4; the blade 8 originally on the upper side rotates to the left side of the rotating shaft 10 and is on standby for the next leveling work, and the process is repeated in turn. As long as the soil is accumulated too much, the resistance breaks through the restriction of the blocking plate 4, the rotating shaft 10 rotates a quarter of a circle to release part of the soil, reduce the load of the tractor, and thus reduce the fuel consumption of the tractor.

[0026] A through slot is formed between the top and bottom of the traction frame 1, the upper end of the blocking plate 4 is independently fixed with a fixed plate 2 through the through slot, and the fixed plate 2 is fixed on the top of the traction frame 1 through two bolts 3. Two through holes are formed in the fixed plate 2, and corresponding threaded holes are formed in the top of the traction frame 1 and are in threaded cooperation with the bolts 3. In use, the fixed plate 2 is fixed on the top of the traction frame 1 by connecting the through holes and the threaded holes through the bolts 3, that is, the detachable connection of the blocking plate 4 is realized. Because the blocking plate 4 is subjected to strong load for a long time, it needs to be replaced regularly, so it is set to be detachable, which facilitates replacement.

[0027] In actual production, the blocking plate 4 can be made of high-quality carbon steel, which has good elasticity and strength and is one of the basic materials for making the blocking plate 4. It can meet the deformation and load relationship of the blocking plate 4 under stress, and ensure the stability and reliability of the blocking plate 4. In production, the selection of the elasticity of the blocking plate 4 needs to be determined according to the experiment how much power can break through the restriction of the blocking plate 4.

[0028] As shown in Figure 3 and Figure 4 , the front and rear sides of the blade 8 and the rotating shaft 10 are provided with a retaining frame for stabilizing the blade 8; the retaining frame includes a fixed disc 7 which is sleeved on the rotating shaft 10, and the fixed disc 7 is provided with a limiting groove 9 for locking each blade 8. In use, because the blade 8 needs to have strong bearing force, the fixed disc 7 and the limiting groove 9 increase the connection strength between the blade 8 and the rotating shaft 10, so that the structure is more stable.

[0029] In actual use, the scraper 8 accumulates soil to a certain amount during the process of land leveling, the resistance increases to break through the limit of the blocking plate 4, the rotating shaft 10 rotates a quarter of a circle, the soil is released by the rotation of the scraper 8, the resistance is reduced, the load of the tractor during the working process is reduced, and the fuel consumption is reduced.

[0030] The embodiment further illustrates the technology;

[0031] The blocking assembly includes a blocking plate 4, and a through slot corresponding to the blocking plate 4 is formed in the top of the mounting frame 1. The blocking plate 4 is hinged to the left and right and swings left and right. The top of the blocking plate 4 independently passes through the through slot and is located above the mounting frame 1. A base is fixed to the right side of the blocking plate 4 at the top of the mounting frame 1. A strong spring is arranged between the base and the right side of the blocking plate 4. In the natural state of the strong spring, the blocking plate 4 is in a vertical state, and the bottom of the blocking plate 4 abuts against any one of the scrapers 8.

[0032] Front and rear hinge holes are formed in the front and rear slot walls of the through slot, and the front and rear side walls of the blocking plate 4 are hinged to the hinge holes through hinge columns, so that the blocking plate 4 can swing left and right. In the natural state of the strong spring, the blocking plate 4 remains in a vertical state and blocks the scraper 8 located on the upper side. In order to rotate the rotating shaft 10, the blocking plate 4 needs to break through the limit of the strong spring and swing. When the damping force of the blocking plate 4 cannot be determined, different strength strong springs can be replaced and repeatedly adjusted.
