Abstract

The invention provides a clod crushing and screening machine for a laboratory, comprising a machine shell, a conveying belt, an electromotor, a power shaft, a temporary clod holding device, a jaw-type clod crushing mechanism located at the upper part inside the machine shell, a roller-type clod crushing mechanism located in the middle inside the machine shell, an automatic clod screening mechanism located at the lower part inside the machine shell and a dust collecting device; two ends of the power shaft are respectively connected with a first bow-shaped rotating shaft and a second bow-shaped rotating shaft, and a first function converter and a second function converter are respectively arranged at the junctions of two ends of the power shaft as well as the first bow-shaped rotating shaft and the second bow-shaped rotating shaft; each of the first function converter and the second function converter comprises an annular clamping part and a fastening bolt; the temporary clod holding device is located below the jaw-type clod crushing mechanism; and the upper part of the temporary clod holding device is connected with the machine shell through a fixing bolt. By using the clod crushing and screening machine provided by the invention, the clod crushing efficiency and effect are improved, the clod screening and dust collecting functions are additionally provided, and meanwhile, clod crushing and screening are realized.

Description

technical field [0001] The invention belongs to the technical field of mechanical pulverization, in particular to a soil crushing and sieving machine for laboratories. Background technique [0002] The amount of soil used in geotechnical engineering is very large, and the demand for crushing and screening of soil in the research process is also very large. However, the existing commonly used laboratory soil crushers have low crushing efficiency and poor soil crushing effect. Ideal, and lack of soil sieving function and dust collection device, which brings great inconvenience to laboratory soil. For this reason, we propose a new type of soil crushing and sieving machine for laboratory use. Contents of the invention [0003] In view of this, the object of the present invention is to provide a soil crushing and sifting machine for laboratory use, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, t...
