Description

TECHNICAL FIELD

[0001] The utility model relates to a field of scarifier, specifically is a kind of adjustable field scarifier. BACKGROUND

[0002] In the field of ginseng planting, the soil quality of ginseng field directly affects the growth and quality of ginseng, and the cutter layout and shape of traditional scarifier are often relatively simple, so it is difficult to achieve uniform cutting of soil. During the scarifying process, it is easy to cause excessive or insufficient loosening of local soil, resulting in uneven soil structure. For example, the cutters of some traditional scarifiers are arranged in a straight line, and during operation, they can only concentrate on cutting the soil in a specific direction, and cannot ensure that the soil in the entire operation area is uniformly treated.

[0003] Uneven soil loosening can cause many problems for ginseng growth. Ginseng roots are sensitive and need to grow in a relatively uniform soil environment. If the soil is not loosened evenly, it may cause ginseng roots to be hindered in some areas, while in other areas, the soil may be too loose to allow stable root growth. In addition, uneven soil structure also affects the distribution of water and nutrients, making it difficult for ginseng to obtain balanced growth conditions.

[0004] Therefore, the skilled person in the art provides an adjustable field scarifier to solve the problems raised in the background art. SUMMARY

[0005] The utility model aims at providing an adjustable field scarifier to solve the problems raised in the background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an adjustable field scarifier, comprising a base, a receiving cavity is formed on the lower end surface of the base, a lifting disc is movably connected in the receiving cavity, a through hole is formed in the center of the lifting disc, an annular sleeve is arranged at the lower end of the through hole, the annular sleeve is rotatably connected to the lower end surface of the lifting disc, a plurality of rotating arms are fixedly connected to the outer wall of the annular sleeve at equal angles, and a plurality of crushing knives are fixedly connected to the lower end surface of the rotating arms at equal intervals.

[0007] As a further scheme of the utility model: left and right slide grooves are respectively formed on the inner walls of the opposite sides of the receiving cavity, a guide rod is fixedly connected between the top wall and the bottom wall of the left slide groove, a reciprocating screw rod is rotatably connected between the top wall and the bottom wall of the right slide groove, and the upper end of the reciprocating screw rod extends to the upper side of the base and is fixedly connected with a handle.

[0008] As a further scheme of the utility model: the left sliding groove is slidably connected with a left sliding block, one end of the left sliding block is fixedly connected with the lifting disc, the right sliding groove is slidably connected with a right sliding block, one end of the right sliding block is fixedly connected with the lifting disc, the left sliding block is slidably connected with the guide rod, and the right sliding block is threadedly connected with the reciprocating screw rod.

[0009] As a further scheme of the utility model: the upper end surface of the base is fixedly provided with a driving part, and the output shaft of the driving part is fixedly connected with a rotating shaft.

[0010] As a further scheme of the utility model: the lower end of the rotating shaft penetrates into the inside of the accommodating cavity, passes through the through hole and the annular sleeve on the lifting disc and extends to the bottom of the base.

[0011] As a further scheme of the utility model: four rectangular grooves are equiangularly formed on the outer wall of the rotating shaft, four rectangular protrusions are equiangularly fixedly connected to the inner wall of the annular sleeve, and the four rectangular protrusions are respectively located in the four rectangular grooves and are slidably connected with the inner wall of the grooves.

[0012] As a further scheme of the utility model: the two side corners of the upper end surface of the base close to the rear end are respectively fixedly connected with handles.

[0013] As a further scheme of the utility model: the two side end surfaces of the base close to the lower end corners are rotatably connected with wheels.

[0014] Compared with the prior art, the utility model has the advantages that:

[0015] 1. The advantage of the circular design: the soil loosening machine adopts a circular disc design, and the crushing knives at the lower end of the rotating arm are distributed in a circumferential manner. This design enables the crushing knives to uniformly cut the soil during the rotation of the rotating arm, avoiding uneven local stress. Compared with the traditional soil loosening machine, the circular disc design can be in large-area contact with the soil, improving the soil loosening efficiency while ensuring the uniformity of the soil structure. Uniform soil structure helps the uniform distribution of water and nutrients in the soil, avoiding local waterlogging or water shortage, and nutrient excess or deficiency. The ginseng can grow and develop better in such a soil environment, improving the yield and quality.

[0016] 2. The crushing knives of the disc-shaped soil loosening machine are distributed in a circumferential manner, which can simultaneously cut the soil in multiple directions during rotation, greatly improving the soil loosening efficiency. Compared with the traditional soil loosening machine, this design can reduce the operation time and labor input, improve the efficiency of ginseng field management, and quickly complete the task in large-area ginseng field loosening, which saves more time for subsequent planting and maintenance work.

[0017] 3、The circular disc design and the circumferentially distributed breaking knives make the soil loosening machine better adapt to different soil conditions, whether heavy clay soil, sandy soil or soil containing stones, the disc-shaped soil loosening machine can realize effective soil loosening operation by adjusting the rotation speed, for example, in heavy clay soil, the rotation speed can be appropriately reduced to increase the cutting force of the breaking knives to overcome the viscosity of the soil, and in sandy soil, the rotation speed can be increased to reduce the depth of the breaking knives into the soil to prevent the soil from being too loose.
