Full-automatic sand sieving machine

Abstract

A full-automatic sand sieving machine relates to the field of the constructional engineering machinery. The sand sieving machine is provided with a frame on which a feeding mechanism, a sand sieving mechanism and a conveying mechanism are arranged, wherein a travelling mechanism is arranged on the frame; the travelling mechanism is composed of a travelling motor, a front driving wheel, a rear driving wheel and a guide wheel all arranged on the frame; the travelling motor is connected to a double belt wheel through a speed reducer; the double belt wheel and a clutch belt wheel form double-belttransmission; tensioning wheels are arranged on the two driving belts of the double-belt transmission, respectively; the tensioning wheels are connected to an external travelling speed switching handle through a tensioning wheel carrier; the clutch belt wheel is connected to a differential mechanism on the front driving wheel through a transmission shaft; a coupling and a universal joint are arranged on the transmission shaft; the coupling is connected to an external travelling mode switching handle; and the front driving wheel is connected to the rear driving wheel through a chain. The full-automatic sand sieving machine is capable of automatically completing all the procedures of travelling, feeding, sand sieving and conveying; when the working position of sieving sand is changed, no external force is needed for drawing, so that time and labour are saved; and the production efficiency is high and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a fully automatic sand screening machine. Background technique [0002] We know that the sand used in construction projects needs to be screened to a certain extent. The initial screening method is to use a sieve to screen manually. This method mainly relies on manpower, which is labor-intensive and low-efficiency. In the case of increasing construction projects , the efficiency of manual sand screening is far from enough; with the development of mechanical equipment and the promotion of applications, various mechanical sand screening equipment has appeared one after another. There are feeding mechanism, sand screening mechanism and conveying mechanism. When the working position of this kind of sand screening machine is changed, it needs to be pulled by external force, which is time-consuming and laborious, and the production efficiency is low.
