Walk-itself-type operation device for three-dimensional protective non-tillage deep scarification and application

Abstract

The invention discloses a walk-itself-type operation device for three-dimensional protective non-tillage deep scarification and application. The walk-itself-type operation device comprises an operation platform and a walking assembly capable of moving the operation platform to a region to be operated, and further comprises a self-moving operation assembly installed on the operation platform and used for moving the operation platform to the region to be operated for operation, wherein a deep scarification and application gun in the self-moving operation assembly is used as a deep scarification and application execution component and can also be used as a movable supporting leg. Variable-plane compaction friction pulling walking is point-position supported walk-itself type walking. By the adoption of the operation mode, the deep scarification and application non-tillage effect is achieved on the condition that soil is not turned and an original soil layer structure is not disturbed, and the deep scarification and application gun can form supporting so as to lift the whole operation platform and a walking assembly, so that the dead weight of the operation system can be used as a movable pivot through which the deep scarification and application gun smoothly enters soil, soil compactness is reduced, and the purpose that the deep scarification and application gun can be rapidly inserted into target soil is achieved.

Description

technical field [0001] The invention relates to the field of agricultural cultivation, in particular to a three-dimensional protective no-tillage deep loosening and deep application self-moving stepping operation device. Background technique [0002] At present, the so-called deep loosening and deep soil preparation operation technology is mainly designed for the cultivation conditions of field crops in plain areas. Generally speaking, the operation system uses tractor-drawn subsoilers or combined soil preparation machines with subsoiling parts to realize plowing and soil plowing in an incomplete sense between rows or all-round deep soil cultivation and soil preparation. The specific operation method is as follows: It mainly pulls plows, shovels, shovels and other subsoiling equipment to move laterally through traction devices (such as high-power tractors), tearing the bottom of the plow or obstructing soil. Its technology and equipment are mainly divided into chisel subsoil...

Problems solved by technology

Generally speaking, the operation system uses tractor-drawn subsoilers or combined soil preparation machines with subsoiling parts to realize plowing and soil plowing in an incomplete sense between rows or all-round deep soil cultivation and soil preparation. The specific operation method is as follows: It mainly pulls plows, shovels, shovels and other subsoiling equipment to move laterally through traction devices (such as high-power tractors), tearing the bottom of the plow or obstructing soil. Its technology and equipment are mainly divided into chisel subsoiling, shovel subsoiling and vibration Subsoiling, but there is no technology and supporting equipment for automated mechanical deep application of powder fertilizers

[0003] The above subsoiling and deep construction methods have the following defects: 1. This technology basically belongs to plane destructive tillage subsoiling, rather than three-dimensional protective no-tillage subsoiling in the strict sense, and it is difficult to achieve the real purpose of subsoiling

According to this purpose, the current subsoiling and soil preparation technology is difficult to fully realize the subsoiling quality requirements of "deep, flat, fine, and solid", that is, the operation depth is generally above 25cm, and the field surface must be leveled after operation. Finely crushed, no missed plowing, consistent depth, solid top and empty bottom, reaching the ready-to-sow state; 2. As far as terrain requirements are concerned, there are many limiting factors for this technology to be applicable to terrain and different crop planting areas, because this technology is mainly suitable for plain areas. It cannot be operated even in relatively flat hilly areas, mountains, and facility agricultural areas; for different crop planting areas, the current technology is limited to the spring and autumn subsoiling operations of single-season field crops in the year, and it is impossible to intertill and subsoil the crops. 3. High energy consumption and inflexible action, because the current subsoiling operation system needs to be driven by a high-power tractor, and there is a lack of supporting equipment. It is not allowed to turn and reverse the car at will during the process, otherwise 4. The quality of the operation is not up to standard, and there are many limiting factors on the soil texture of the operation. The reason is that the depth of subsoiling is relatively large. When the depth exceeds 30cm, there may be insufficient power, and the operating environment requires no roots in the plow layer. During the operation process, it is required that there should be no high stubble in the work area, and the straw after stubble should not be laid too thick on the ground, otherwise the ground friction will be too small and the machine will slip and it will be difficult to move forward.

In addition, incomplete subsoiling will occur during the subsoiling process, often leaving hard ridges with different degrees of subsoiling that have not been subsoiled or formed by different depths of subsoiling shovels; 5. This technology is mainly used for relatively Dry land in spring and autumn, rainy season, ice and snow season, and land with high water content cannot be fully loosened. Otherwise, due to the easy action of mechanical compaction, hard and dry ridges often appear or it is difficult to tear the frozen soil layer by ice and snow; 6. Repeated operations will compact and disturb the surface soil, because when the machine is inserted into the soil, the machine will travel with the vehicle, causing the soil to be rolled repeatedly, which will cause great disturbance and damage to the soil, and accelerate the soil erosion of the surface soil to a certain extent
