Description

A kind of broken husky sand sieving machine of civil engineering classification
Technical field
The present invention relates to civil engineering training equipment technical field, specifically a kind of broken husky sieve of civil engineering classification is husky Machine.
Background technology
Sand sieving machine is essential instrument on Construction of Civil Engineering building site, and current Sand screen is due to the limit in structure System, be all often be sieved by one piece of metal mesh tiltedly put, but its exist be sieved area it is small, cannot adequately to sand into Row filtering, it is often necessary to secondary sieving be carried out to filtered sand, cause time-consuming and laborious, and screening efficiency is too low;In addition, being Applied to various construction sites, meet the needs of different constructions are to fineves such as sands, often the fineves such as sand is carried out different Grain size is classified, and then develops and classification sand sieving machine occur, but existing sand sieving machine mostly uses the sieve progress of different meshes Multistage screening coordinates the vibration of vibrator is whole quickly to sieve material to realize, but existing Multi-stage screening machine discharging knot at present Structure is complicated, or only with a discharge port, be easy to cause the material later stage in this way and the case where batch mixing, while whole discharging behaviour occurs Make it is troublesome, it is inconvenient.
Publication No. is that the Chinese patent of CN 107309162A discloses a kind of civil engineering classification sand sieving machine, including sieve The top surface of case, the screen box offers sand inlet, and is welded with into sand hopper at the sand inlet;The bottom of screen box is tapered Structure, and the lowermost end of screen box offers sand export, and the sand export in the form of welding to being connected to the pipe that shakes out, the invention is logical Release locking nut is crossed, then rotating shaft so that side-lower tilts sieve backwards, and the sandstone material on sieve can be through collection at this time The front opening of hopper rolls into aggregate bin, and then the back outlet through aggregate bin rolls into discharge tube, finally soft from discharging It is discharged at pipe, the entire process that discharges is rapid, more quick to operate without unpacking to equipment, and level-one screening dress Set, two level screening plant and three level screen device have independent discharging structure, therefore the discharging of each screening component is independent of each other, The case where traditional equipment easily causes batch mixing from one outlet discharge is avoided to occur.
But a kind of civil engineering of above-mentioned technical proposal exists with classification sand sieving machine:1) using manual elastic locking screw every time Mother makes sieve tilt down the mode of sand discharge, and manpower substantial length of operation is needed to control, and intelligence degree is not high, sieves husky working efficiency Relatively low, static tilt sand discharge, which often generates, to be left or is discharged not exclusively;Though 2) being provided with three-level exciting screens layered structure, the Level-one sieve is easy not screening caused by being put into the reasons such as former sand is more or deposition is thicker and just be discharged completely, and screening is not enough; 3) grains of sand of larger particles can not be decomposed with screen utilize, with traditional sand sieving machine there are identical can only screen cannot be broken Husky problem.
