Problems solved by technology

The currently used dry soil crushing equipment is relatively simple, and the crushing process is only dissolved after preliminary crushing. The poor crushing effect leads to slow dissolution speed. At the same time, there is no screening device after crushing, and some larger stones are often Dissolved in the dissolution bottle, affecting the analysis results

Abstract

The invention discloses a dry soil fine crushing and screening device for soil analysis in a polluted area, which comprises a device case, a preliminary crushing roller, a double-axis motor, a first cam, a sealing partition, a fine crushing roller and a screening box. A slider is slidably installed on the lower side of the material plate A, and a packing plate is fixedly installed on the lower side of the sliding block. One side of the packing plate is fixedly connected with a first connecting rod, and the first connecting rod passes through the device chassis and is connected with a top block. A. A fine crushing roller is installed in rotation inside the casing of the device, and arc-shaped plates are arranged on the left and right sides of the fine crushing roller; a screening box is slidingly installed on the guide rod. The crushing and screening device can carry out preliminary crushing and fine crushing, so as to improve the effect of crushing. At the same time, it can carry out fine crushing in batches when performing fine crushing after preliminary crushing, thereby reducing the working pressure of the fine crushing roller and improving the effect of crushing. At the same time, after the crushing is completed, the arc-shaped plates on both sides can be moved to both sides, so as to facilitate the falling of the crushed dry soil.

Description

technical field [0001] The invention relates to a crushing and screening device, in particular to a dry soil fine crushing and screening device for soil analysis in polluted areas. Background technique [0002] Before the analysis and test of soil nutrients, the soil samples need to be pulverized to facilitate the effective dissolution of chemical components in the soil. The currently used dry soil crushing equipment is relatively simple, and the crushing process is only dissolved after preliminary crushing. The poor crushing effect leads to slow dissolution speed. At the same time, there is no screening device after crushing, and some larger stones are often Dissolved in the dissolution bottle, affecting the analysis results. Contents of the invention [0003] The object of the present invention is to provide a dry soil fine crushing and screening device for soil analysis in polluted areas, so as to solve the problems raised in the above-mentioned background technology. ...
