Sand falling amount control system of screening machine

Abstract

The invention discloses a sand falling amount control system of a screening machine. The sand falling amount control system comprises a supporting rod, a shell and dust collecting bags; a dustproof cover is installed on the right side of the supporting rod, moreover, a discharging pipe is fixed above the dustproof cover, a metering pipe is installed on the left side above the discharging pipe, moreover, a piston is arranged inside the metering pipe, a first push plate is installed on the right side above the discharging pipe, and a second push plate is fixed above the first push plate; and a sliding groove is formed above the second push plate, moreover, a fixing pipe is installed above the sliding groove, the fixing pipe is fixed under the shell, moreover, a motor is arranged on the leftside inside the shell, a rotating shaft is installed on the left side of the motor, and stirring rods are fixed on the rotating shaft. The sand treatment sand falling amount control system with a dustremoval function is provided with the dustproof cover, the discharging pipe is shielded through a circular structure at the bottom of the dustproof cover, and dust generated by sand falling from thedischarging pipe is absorbed through air suction covers.

Description

technical field [0001] The invention relates to the technical field of sand treatment, in particular to a control system for the amount of sand falling out of a screening machine. Background technique [0002] Sand treatment is a series of treatments such as crushing, filtering, and drying of sand. After the sand is processed, the sand must be used. Therefore, there is a sand treatment shakeout system on the market. Although the sand treatment shakeout system currently on the market There are various types of systems, but there are still some shortcomings. For example, the traditional shakeout system cannot control the amount of shakeout well during the shakeout process, resulting in too much or too little shakeout, which affects the staff. In the process of falling sand, a large amount of dust will be generated, and there will be dust splashing when pouring sand and gravel at the material inlet, which will affect the work of the staff, and the sand and gravel will easily ac...

Problems solved by technology

[0003] The purpose of the present invention is to provide a control system for the amount of sand shakeout of a screening machine, to solve the problem that the traditional shakeout system on the market cannot control the amount of sand shakeout well during the sand shakeout process, resulting in sand shakeout. Too much or too little will affect the use of the staff, and a large amount of dust will be generated during the sand falling process, and there will be dust splashes when pouring sand and gravel at the feed port, and the sand and gravel are easy to accumulate.
