Problems solved by technology

[0003] The traditional sand screening machine is bulky and inconvenient to move. In addition, it needs the cooperation of the transmission mechanism to transport the coarse sand on the ground to the sand screening device for screening. The operation is troublesome. In addition, the requirements for the site are higher. For some small projects, there is no corresponding The current sand screening device can only rely on manual sand screening, which is very inefficient and the screen holes are easy to block

Abstract

The invention discloses a scattering type high efficiency sand screening device. The scattering type high efficiency sand screening device comprises a car body; a crawler is arranged under the car body; the left side of the car body is hinged to rotating shafts through a first hinge shaft, a first driving shaft is rotatably connected between the rotating rods, the first driving shaft is fixedly connected with a circumferentially distributed throwing plate, and a guiding cover is arranged above the throwing plate. The guiding cover extends into the car body, and the inner wall of the guiding cover is evenly distributed with conical teeth; the car body is provided with a screen plate. Coarse sand is scattered by means of a throwing plate and a guiding cover, and sand blocks are initially broken by the conical teeth, later screening is convenoent and the screening efficiency is improved; an eccentric roller and a screen plate are arranged so as to vibrate the screen plate up and down, ensure the screening efficiency and avoide the blockage of a screen hole.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a throwing type high-efficiency sand screening device. Background technique [0002] The sand sieving machine imitates the working principle of artificially using the inclined screen to screen sand. It adopts a flat rolling screen cylinder and ensures that the material flow can be continuously rolled for more than five circles between the multi-turn inner spiral blades in the screen cylinder, so that the sand material can be repeatedly screened. It is fully discrete and separated by tumbling and sliding; it is different from the pushing and burying of large and small materials caused by inclined roller sieves, and the screening process is rushed; it is also different from the vibration and mixing of large and small materials caused by inclined vibrating screens. [0003] The traditional sand screening machine is bulky and inconvenient to move. In addition, it needs the coope...
