Jaw crusher applied to soil

Abstract

The invention relates to a jaw crusher applied to soil. The jaw crusher comprises a frame and a crushing auxiliary mechanism, wherein the crushing auxiliary mechanism comprises a fixed jaw plate, a movable jaw plate, a fixed jaw plate supporting plate and a movable jaw plate supporting plate; the fixed jaw plate is fixedly mounted on the fixed jaw plate supporting plate; the movable jaw plate is removably mounted on the movable jaw plate supporting plate; a first crushing cavity is formed between the fixed jaw plate supporting plate and the movable jaw plate supporting plate; the lower parts of the fixed jaw plate supporting plate and the movable jaw plate supporting plate are in extension connection with a fixed jaw tooth supporting plate and a movable jaw tooth supporting plate respectively; a second crushing cavity is formed between the fixed jaw tooth supporting plate and the movable jaw tooth supporting plate; the second crushing cavity forms a parallel cavity type structure with equally-spaced top and bottom; a plurality of fixed jaw teeth are fixedly mounted on the fixed jaw tooth supporting plate; movable jaw teeth are removably mounted on the movable jaw tooth supporting plate; the fixed jaw teeth are meshed with the movable jaw teeth. The jaw crusher applied to soil has the advantages of simple structure, low production cost, high crushing efficiency, long service life, low time consumption, low energy consumption, convenience in maintenance and capability of uniformly and finely crushing large-particle hardened soil.

Description

Technical field [0001] The invention relates to a crushing machine, which is specifically a jaw crusher for crushing soil under a vegetable greenhouse. Background technique [0002] my country's urbanization is developing rapidly, and its demand for vegetables is also increasing. Intensive vegetable production (mainly represented by vegetable greenhouses) is one of the main development directions in the future. In vegetable greenhouses, farmers can adjust the microclimate in the greenhouse to create suitable environmental conditions for vegetable growth, thereby extending the vegetable production season and increasing vegetable output. This not only has a greater significance for increasing production and income, but also because it relieves the tension of urban vegetables in the off-season Supply and have positive social benefits. Vegetable greenhouses (including solar greenhouses, etc.) have developed rapidly in my country and have expanded from the north to all parts of the ...

Problems solved by technology

[0003] Usually, crushing the compacted soil with a pulverizer is one of the effective ways to reduce soil compaction. However, in the actual application of the pulverizers on the market, it is difficult to completely pass the material after one crushing, and it is necessary to return the material to re-crunch many times. This increases the workload of personnel and equipment, is time-consuming, inefficient, and consumes a lot of power.

Moreover, due to the large area of ​​soil under the vegetable greenhouse and the large amount of soil, conventional hammer mills and knife mills can only crush light soil, and the processing capacity cannot meet the requirements, which affects work efficiency. When a jaw crusher with a large processing capacity is crushing, the rack or teeth on the movable jaw plate are easily damaged and need to be replaced in time, but the existing situation is that once the movable jaw plate is damaged, the entire movable jaw plate needs to be replaced. The jaw mechanism is disassembled for replacement, and maintenance is difficult
