Abstract

The utility model belongs to a special device for separating sandstones for construction use, which solves the problems of high labor intensity and low work efficiency in the prior art. The utility model is mainly formed by the organic combination of a multilayer screen mesh, a support frame with adjustable height, rocking equipment of which the motives power is supplied by a diesel engine or a vibrorammer used as the rocking equipment and auxiliary connection shafts. The work efficiency of the utility model is hundredfold of that of people, four kinds of sandstones of different granularity can be simultaneously separated and elected, and the utility model can be widely used for sandstone fields, building sites, etc.

Description

Quick sand sieving machine

The utility model relates to a kind of with the device of solid material by size sorting, belongs to the quick sand sieving machine of sorting sandstone sand for building especially.

In the prior art, when sorting sandstone, sand, used separating sieve all is made up of a screen frame (unit) and screen cloth.The concrete operations way is separating sieve to be supported to and ground forms an inclined-plane, with iron plate sand is raised on the compass screen surface then, sieves by the impulse force of sand and gravity and gets sand.It is very big to get sand labour intensity with this original way sieve, and efficiency is very low, can not satisfy the demand of modern architecture industry far away.When the sand of need screening wet, the sorting difficulty increased all the more, causes waste of manpower, material resources.

The purpose of this utility model provides a kind of low novel quick sand sieving machine of high efficiency, labor strength that overcomes the deficiencies in the prior art part.

The purpose of this utility model reaches by following measure:

Sand sieving machine is made up of the connecting axle of up-down adjustment mechanism, screen cloth and support on screen cloth, support, the support and frame bottom and the shaking device on the screen cloth fast.

The purpose of this utility model can also realize by following measure:

Screen cloth is hierarchal arrangement from top to bottom from coarse to fine, and four jiaos are connected as a single entity by support, and wherein the superiors' screen cloth has delivery sheet, and two, three layers of screen cloth have the side delivery sheet.

Shaking device can select for use the tank bracket of bearing bracket stand and screen cloth directly to weld, and connects band eccentric bearing in both sides under the bearing bracket stand, and the sheave of bearing end is connected with the driving wheel of diesel engine by the V-belt.

Shaking device also can adopt under screen cloth and directly make shaking device by the dress vibrator.

When using this sand sieving machine, can determine the gradient of screen cloth by the activity up-down adjustment mechanism that regulates support according to the humidity of sandstone, usually, humidity is big more, gradient is more little, so that make the sand material long more in the time that the screen cloth scend is sieved, on the contrary also anti-.The gradient of regulating screen cloth is considered the number of plies of screen cloth simultaneously, and the number of plies is many more, and gradient is just more little.When adjusting gradient, connecting axle between screen cloth and the support, between support and the crossbearer can rotate as required, to reach the requirement of any adjustment angle.

Up-down adjustment mechanism can adopt the pin-and-hole of porous and the way that pin is used, and the pin nail has just been determined the gradient of screen cloth at fixing pin-and-hole.

The delivery sheet of upper strata screen cloth is located bottom at it, and the material that sieved is sent the place away from sand sieving machine thus, pulls away in order to entrucking.The lower end of the screen cloth of two layers and three layers also left and tiltedly upright to the right fixing with plate washer, two, three layers of material that sieve also the while delivered to the both sides of sand sieving machine respectively, be convenient to separate varigrained sand.

When non-transformer, the power of shaking device just can be selected diesel engine for use; When electricity is arranged, vibrator can be installed on screen frame directly.

Drawing is described as follows:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model shaking device schematic diagram.

The good effect that the utility model produces is: improved widely efficiency, and vertical by artificial one hour sieve sand 1 Side's rice is not enough, is increased to and per hour can sieves 80 cubic metres of sands, and can disposablely just can sift out varigrained four kinds of sand Son, labor strength reduces greatly.

Embodiment:

1, screen cloth is formed by three layers, upper strata screen cloth [1] delivery sheet [6] arranged bottom, delivery sheet is manufactured with the 2mm steel plate.The sand material that has tiltedly upright marker board [7] to sieve bottom of second layer screen cloth [2] is delivered to the sand sieving machine left side.The sand material that the tiltedly upright bottom marker board of the 3rd layer of screen cloth [3] will sieve is delivered to the right side of sand sieving machine.Support [12] and screen cloth edge all are to use angle bar.Up-down adjustment device [4] is selected pin, pin-and-hole structure for use.With angle bar welding, and be connected by connecting axle [8] between the support [12] between screen cloth [1], [2], [3].When shaking device [11] selects for use diesel engine to do power, a bearing bracket stand [9] is lived in each fixing weldering on two body side frames of bottom screen cloth, and bearing bracket stand [9] is connected with bearing, and respectively there is an eccentric wheel [5] the bearing both sides, one side of bearing has sheave [10], links to each other with diesel engine by the V-belt.

2, having under the situation of power supply, change shaking device into vibrator and get final product, other are constant.General screen mesh size is grasped about 3 meters * 4 meters.

Claims

1, a kind of quick sand sieving machine is characterized in that: screen cloth [1], [2], [3], to fix by support [12] layering, and the lower end of support [12] is up-down adjustment mechanism [4], the connecting axle [8] of support [12] bottom is gone up fixedly vibrating device [11].

2, quick sand sieving machine according to claim 1, it is characterized in that: screen cloth [1], [2], [3] are hierarchal arrangement from top to bottom from coarse to fine, four jiaos are connected as a single entity by support [12], and the superiors' screen cloth [1] has delivery sheet [6], and second and third layer screen cloth has side delivery sheet [7].

3, quick sand sieving machine according to claim 1, it is characterized in that: shaking device [11] selects for use bearing bracket stand [9] and screen cloth [1], [2], [3] framework directly to weld, the bearing that connects both sides band eccentric wheels [5] under the bearing bracket stand [9], the sheave of bearing end [10] is connected with the driving wheel of diesel engine by the V-belt.

4, quick sand sieving machine according to claim 1 is characterized in that: smash device in the direct installation in the lower end of screen cloth [1], [2], [3] and make shaking device [11].
