Description

Technical Field

[0002] The field raising project is an engineering measure taken to reduce the flooding of cultivated land by raising the cultivated land to a level that is no longer flooded when constructing a water storage project. As the country pays more attention to the protection of cultivated land resources, this engineering measure is being used more and more widely in water conservancy and hydropower construction projects.

[0003] At present, in the construction process of the field raising project, the cultivated soil is filled in. The current common filling method is to use a dump truck to transport the cultivated soil to the construction site for unloading, and then spread the cultivated soil manually. However, since the cultivated soil is often excavated by an excavator and directly loaded on the dump truck, there will be large pieces of soil in the cultivated soil unloaded on site. Therefore, due to the lack of suitable crushing means during manual spreading, a large amount of manpower is often required to carry out the crushing operation, resulting in low efficiency in spreading and filling the cultivated soil.

[0030] The above structure is used specifically in the construction of paving and filling cultivated soil in the field lifting project. When the cultivated soil is crushed for use, the cover 1 above the top of the conveyor belt 3 is combined with a crushing and stirring component 2. Then, the crushing and stirring component 2 can crush the hardened large blocks of soil transported by the conveyor belt 3 evenly, without consuming manpower to crush the soil blocks specifically, and at the same time, it is convenient to better control the paving thickness. Specifically, since the outer ends of the crushing roller 201 of the crushing and stirring component 2 are coaxially fixed There is a fixed end seat 206, and the end seats 206 at both sides are detachably mounted with an arc-shaped mounting plate 202 through the disassembly and assembly assembly 4. The arc-shaped mounting plate 202 is coaxially covered on the outside of the crushing roller 201 and a plurality of crushing blades 203 extending radially outward are fixed on the outer surface. Then, the crushing roller 201 is driven to rotate by the transmission box 204, so that the crushing blades 203 can be rotated to crush and mix the hardened bulk soil material conveyed by the conveyor belt 3, which simplifies the crushing and mixing operation of the hardened bulk soil material.

The locking rod 407 only needs to be disengaged from the locking hole 405 to make the matching block 402 slide out of the matching groove 401 and the arc-shaped mounting plate 202 and the crushing blade 203 be detachably assembled on the outside of the crushing roller 201. The arc-shaped mounting plate 202 and the crushing blades 203 are detached from the outside of the crushing roller 201. The combination and disassembly of the arc-shaped mounting plate 202 and the crushing blades 203 on the outside of the crushing roller 201 are simple and easy to implement. It is convenient to quickly combine the arc-shaped mounting plate 202 and the crushing blades 203 on the outside of the crushing roller 201 to crush and mix the hardened large soil materials. At the same time, it is convenient to subsequently detach the arc-shaped mounting plate 202 and the crushing blades 203 from the outside of the crushing roller 201 to clean and reshape the crushing blades 203 for maintenance.
