Description

Technical Field

[0001] The utility model relates to the technical field of soil treatment, in particular to a spraying device for soil treatment. Background Art

[0002] Soil refers to a loose layer of material on the surface of the earth, composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals formed by weathering of rocks, organic matter produced by the decomposition of animal and plant and microbial remains, soil organisms (solid phase matter) and water (liquid phase matter), air (gaseous phase matter), oxidized humus, etc. Soil management, also known as soil remediation, is a technical measure to restore the normal function of contaminated soil. In order to improve the quality of agricultural soil, spraying devices are needed for management.

[0003] In the actual operation process of using the soil treatment spraying device, the treatment liquid is sprayed directly on the soil surface. Affected by the different depths of soil that need to be treated, for the spraying device, when treating thicker or deeper soil layers, the treatment liquid may not be transported to the deep soil layer for uniform and effective treatment. In order to effectively treat the deep soil, personnel are required to dig and break the soil before spraying to facilitate subsequent spraying treatment, which causes personnel to spend a certain amount of time on the step of digging the soil layer, increasing the workload of personnel, thereby reducing the practicality of the spraying device.

[0004] Chinese utility model patent CN202322867283.7 discloses a soil treatment spraying device, including a base plate, a water tank is provided on one side of the top of the base plate, a mounting groove is provided on the other side of the top of the base plate, a mounting shell is provided below the base plate, one side of the mounting shell is open, and a second motor is fixedly installed inside, the output end of the second motor is driven and connected to a spiral drill rod, and an adjustment component connected to the mounting shell is provided on the top of the base plate and in the mounting groove. During the use of the utility model, the soil treatment spraying device can effectively spray and treat deep soil, avoiding the problem that when treating thicker or deeper soil layers, the treatment liquid may not be transported to the deep part of the soil layer for uniform and effective treatment, and personnel are required to dig and break the soil before spraying to facilitate subsequent spraying treatment, which results in time-consuming and laborious operation of personnel in soil treatment, thereby reducing the burden on personnel and improving the practicality of the spraying device.

[0005] It can solve some of the above problems, but there are still major defects:

[0006] The scraper is driven by a pulley group, which causes the soil drilled by the auger rod to pile up on one side of the equipment. After the spraying is completed, it takes a lot of manpower and material resources to restore the soil surface, which is inconvenient to use;

[0007] The soil drilled up by the auger rod will be re-covered by the movement of the scraper, affecting the spraying effect. Summary of the invention

[0008] Technical problems to be solved by the utility model

[0009] The scraper is driven by a pulley group, which will cause the soil drilled out by the auger rod to pile up on one side of the equipment. After the spraying is completed, the restoration of the soil surface is more labor-intensive and inconvenient to use. The soil drilled up by the auger rod will be re-covered under the action of the scraper movement, affecting the spraying effect.
