Sand screening device with automatic feeding and discharging functions

Abstract

The invention discloses a sand screening device with the automatic feeding and discharging functions. The sand screening device comprises a base frame. An edge baffle and a pressure sensor are arranged on the upper portion of the base frame. A multi-stage oil cylinder is arranged on one side of the base frame and matched with a discharging plate. The base frame is connected with a middle frame through a set of stand columns. A controller is arranged in the middle of the middle frame. A sand screening motor is arranged at one end of the middle frame and matched with a screen. The middle frame is matched with a feeding hopper through a support. A feeding motor is arranged on the lower portion of the feeding hopper and matched with a feeding wheel. A solar cell panel and an accumulator are arranged on the upper portion of the feeding hopper. The accumulator is electrically connected with lighting lamps at the ends of an extending-and-contracting rod. The electric sand screening manner is adopted in the sand screening device with the automatic feeding and discharging functions, automatic sand screening and discharging can be achieved, the workload of construction workers is relieved greatly, the sand screening quality is guaranteed while efficiency is improved, the solar lighting function is achieved, and part of electric energy is saved.

Description

technical field [0001] The invention relates to the field of sand screening devices, in particular to a sand screening device for automatic feeding and unloading. Background technique [0002] The reform of sheds across the country is in full swing, the number of buildings has increased dramatically, and the construction of buildings is inseparable from the use of sand. As an indispensable material for construction, sand needs to be screened before it can be put into use. Currently, the construction site is under construction and transported to the construction site The sand is usually screened by the construction workers with a sieve, and the sieve is placed sideways on the ground, and the sand is scooped up with a shovel and scattered to the screen. , Efficiency is low, is unfavorable for improving the speed of building construction, now needs a kind of equipment that can automatically sieve sand to make up for this deficiency, to improve the speed and quality of sieve san...

[0002] The reform of sheds across the country is in full swing, the number of buildings has increased dramatically, and the construction of buildings is inseparable from the use of sand. As an indispensable material for construction, sand needs to be screened before it can be put into use. Currently, the construction site is under construction and transported to the construction site The sand is usually screened by the construction workers with a sieve, and the sieve is placed sideways on the ground, and the sand is scooped up with a shovel and scattered to the screen. , The efficiency is low, which is not conducive to improving the speed of construction. Now a kind of equipment that can automatically screen sand is needed to make up for this deficiency, so as to improve the speed and quality of sand screening.
