Lime soil stirring and spreading device based on stepless speed change principle

Abstract

The invention relates to the technical field of lime soil stirring, and discloses a lime soil stirring and spreading device based on a stepless speed change principle. The lime soil stirring and spreading device comprises a shell, wherein a rotating shaft is movably connected to the left end of the inner wall of the shell, a fixed block is fixedly connected to the right end of the rotating shaft, a connecting block is fixedly connected to the right end of the fixed block, a cam is fixedly connected to the outer surface of the connecting block, a working box is fixedly connected to the right end of the connecting block, a connecting shaft is fixedly connected to the left end of the inner wall of the working box, and a conveying mechanism is fixedly connected to the outer surface of the connecting shaft. A pressure rod moves downwards, so that a crushing mechanism is pushed to move downwards, and the crushing mechanism is located just above the conveying mechanism, so that the crushing mechanism is matched with the outer surface of the conveying mechanism when moving downwards, large soil is compacted and crushed into small blocks when internal lime soil moves, internal bulk mixtures are crushed during mixing, and the mixing is uniform.

Description

technical field [0001] The invention relates to the technical field of lime-soil mixing, in particular to a lime-soil mixing and spreading device based on the principle of infinitely variable speed. Background technique [0002] Lime soil is one of the traditional building materials in northern China. It is made by mixing and compacting clay and lime with water. Lime soil is mainly distributed on the coarse acidic parent material in the humid cold temperate zone, including lime soil, brown podzolite and submerged lime soil. In order to prevent foundation settlement in the industry, lime soil mixers are needed to mix soil and lime to produce a mixture to be filled into the foundation, so that the foundation can be laid in the early stage of construction. [0003] But at present, there are still defects that need to be overcome when mixing lime soil. When mixing lime soil, quicklime and soil need to be mixed in a proportion. At the same time, it affects the proportion require...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a lime-soil mixing and spreading device based on the principle of infinitely variable speed, capable of accelerating internal mixing, and at the same time crushing the internal bulk mixture during mixing, so that the mixing is more uniform and comparable to that of the machine When the speed is too fast, the advantage of slowing down the internal speed solves the need to mix quicklime and soil in a proportion when mixing lime soil. However, if the soil is large during the round, it is not easy to achieve the mixing effect. At the same time Affect the ratio requirements, and at the same time, the stirring of the internal mixing is not uniform. At the same time, if the stirring speed is too fast, the internal parts are easily damaged under the action of huge inertia
