Description

Technical Field

[0001] The utility model belongs to the technical field of subsoilers, and particularly relates to a subsoiling, leveling and rolling working component. Background Art

[0002] The statements in this part only provide background technical information related to the utility model, and do not necessarily constitute prior art.

[0003] A subsoiler is a device for deeply tilling and loosening the soil. In the prior art, a power take-off box is mostly used to connect multiple rotating shafts, and spiral blades are installed on the rotating shafts to achieve deep tillage operations. In the prior art, patent CN108738396B discloses a new type of hydraulically driven vertical spiral subsoiler. The subsoiling component uses spiral blades to cut the soil mass, and a scraping plate is connected to the subsoiling component to scrape the surface of the soil after deep tillage.

[0004] The following technical problems exist in the above technical solutions:

[0005] 1) The resistance of the spiral blade entering the soil is large. When the subsoiler drives the subsoiling component to move forward, the lower surface of the spiral blade is easily worn when cutting and rubbing the soil. During the cutting process, the cut soil forms a blockage to the blade, resulting in a large resistance to the operation of the machine.

[0006] 2) Since the soil mass after deep tillage is loose, there are a large number of pores both inside and on the surface. Only scraping the surface of the soil mass after deep tillage cannot reduce the pores on the surface and inside of the soil mass, which leads to the easy evaporation of the water in the soil mass and causes a large loss of the entropy of the soil mass.

One end of the frame-shaped fixing bracket 1 away from the drill shaft 3 is movably connected with a leveling assembly 4, and a roller 5 is fixedly connected. The roller 5 is arranged behind the leveling assembly 4.

[0028] As Figure 2 shown in the figure, the frame-shaped fixing bracket 1 includes two long-side cross beams 11 and two short-side cross beams 12. The long-side cross beams 11 and the short-side cross beams 12 are fixedly connected in sequence. As Figure 1 shown in the figure, a first ear plate 13 is arranged at the bottom of one end of the short-side cross beam 12 away from the drill shaft 3. On this side, a plurality of second ear plates 14 are arranged on the long-side cross beam 11 connected to the short-side cross beam 12. In this embodiment, the number of the second ear plates 14 is three, and the intervals between the second ear plates 14 are equal. One of the second ear plates 14 is arranged at the central position of the long-side cross beam 11. It can be understood that the number of the second ear plates 14 can also be an even number, such as four, and they are symmetrically distributed with the central position line of the long-side cross beam 11 as the symmetry line.

As Figure 1 shown in the figure, a pin shaft hole is arranged on the first ear plate 13. The frame-shaped fixing bracket 1 is movably connected with the leveling assembly 4 through the second ear plate 14 and the first ear plate 13.

[0030] In this embodiment, as Figure 1 shown in the figure, a flange is arranged at the bottom of the transmission shaft 21, and a flange of the same size is also arranged at the top of the drill shaft 3. Bolts are passed through the flanges of the transmission shaft 21 and the drill shaft 3 and tightened to fixedly connect the transmission shaft 21 and the drill shaft 3. It can be understood that the transfer case 2 adopts the existing technology and can drive a plurality of transmission shafts 21 to rotate simultaneously.

[0031] In this embodiment, as Figure 1 shown in the figure, a plurality of groups of fixing bolt holes 32 are arranged at equal intervals on the spiral blade 31. The number of each group is two, which are used for fixedly connecting auxiliary blades. It can be understood that the auxiliary blades are tillage blades in the existing technology and have a certain angle. Its purpose is to enhance the ability of the spiral blade to enter the soil, reduce the resistance of the spiral blade to enter the soil, enhance the ability to cut the soil when the deep tillage assembly moves forward, and protect the lower surface of the spiral blade.

[0032] In this embodiment, as Figure 1As shown in the figure, the leveling assembly 4 includes a leveling plate 41. The bottom of the leveling plate 41 is provided with a leveling portion 411 with an inclined surface, which can level the soil after deep plowing.
