Abstract

The utility model belongs to the field of devices for screening rockfill materials, and discloses a device for screening the rockfill materials. The device for screening the rockfill materials comprises two parts: a screen mesh and a support. The screen mesh consists of a frame body, a mesh body and mesh openings. The mesh body is formed by arranging mesh strips at an equal interval, wherein each mesh strip is made of a solid steel roller; an operating rod can be inserted into one end of one mesh strip; the mesh strips can be embedded into the frame body, and can freely rotate; each mesh opening is rectangular; the support consists of a front support and a rear support; the front support is lower than the rear support, so that the screen mesh and the horizontal plane form an angle of 30-45 degrees; the joints of the screen mesh and the support are respectively provided with a spring. The device is simple in structure, convenient to operate, good in screening effect, low in labor strength, high in efficiency and good in construction quality, and mechanized screening of the rockfill materials is realized.

Description

A kind of stockpile screening plant

Technical field

The utility model relates to stockpile screening plant field, is specifically related to a kind of rock-fill concrete stockpile screening plant.

Background technology

Rock-fill concrete is a kind of novel low-carbon environment-friendly concrete, adopts self-compacting concrete to fill rockfill, and wherein enrockment volume ratio generally can reach the 55%-60% of rock-fill concrete volume.In order to guarantee the construction quality of rock-fill concrete, require enrockment particle diameter used more than 30cm.In practice of construction, because transhipment and the collision of enrockment can exist disintegrating slag and inferior footpath piece stone, generally rely on excavator and human assistance to choose roughly the part meeting the demands in enrockment material source.

This mode can meet certain engineering demand, but still Shortcomings part:

1. the control of enrockment particle diameter is affected by workman's technical operation level and sense of responsibility, and quality control difficulty is larger.When in rockfill, inferior footpath piece stone is more, self-compacting concrete filling channel is blocked, causes the local leakiness of rock-fill concrete, forms mass defect;

2. complicated operation, efficiency is lower, easily affects construction speed.

Summary of the invention

The purpose of this utility model is to solve the deficiency of enrockment screening technology, and a kind of simple in structure, easy to operate, stockpile screening plant that screening effect is good is provided, and realizes do mechanization operation, and labour intensity is low, efficiency is high, construction quality is good.

The utility model is achieved through the following technical solutions.

A stockpile screening plant, comprises screen cloth and bearing two parts, and described screen cloth is comprised of framework, dictyosome and mesh, and dictyosome is embedded in framework, and dictyosome is formed by equidistant layout of net bar, and mesh is rectangle; Bearing consists of front bearing, rear support; Screen cloth and bearing junction are provided with spring.

Wherein, front height of support, lower than rear support, makes screen cloth become 30 °-45° angle with horizontal plane, and enrockment relies on deadweight along screen cloth landing, because angle is excessive, does not cause enrockment landing fast simultaneously, and screening effect is poor.

Wherein, the solid steel rider of net strip adoption, steel rider is cylindrical, and wearability is good, and enrockment is easy to landing on screen cloth.

Wherein, net bar is embedded in framework, can rotate freely, and end welded end plate is to fix its position in framework.Enrockment landing drives the rotation of net bar, and then promotes enrockment landing, reduces card stone phenomenon and occurs.

Wherein, net bar one end can update bar, and the action bars body of rod is mutually vertical with handle, is easy to grasp and the application of force.While there is card stone phenomenon, action bars is inserted in net bar and fixed, rotating operation bar drives the rotation of net bar, makes enrockment landing.

Wherein, spring is arranged on the junction of each screen cloth and bearing.Slow down the impact of enrockment to bearing, extension fixture service life; Spring is used the vibrations that produce the little amplitude of low frequency simultaneously, is conducive to reduce the probability of card stone.

The utility model stockpile screening plant, when stockpile sieves, particle diameter stone not up to standard is screened out by mesh, falls into the sieve end, and bulk enrockment relies on deadweight to slide and drop on before screening plant along screen cloth, then concentrates and piles into stock ground.The beneficial effects of the utility model are:

1. screening effect is good, avoids small particle diameter enrockment to put in storage, and guarantees construction quality.

2. realize do mechanization operation, save manpower and time, accelerating construction progress.

The specific embodiment

Embodiment 1

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figure 1, stockpile screening plant described in the utility model, comprises screen cloth 1 and bearing 5,6 two parts.Screen cloth 1 is comprised of framework 2, dictyosome 3 and mesh 4, and dictyosome 3 is embedded in framework 2, and dictyosome 3 is formed by equidistant layout of net bar 8, and mesh 4 is rectangle; Bearing consists of front bearing 5, rear support 6; Screen cloth 1 is provided with spring 7 with each junction of bearing 5,6.Action bars 9, end plate 10, nut 11 are all on net bar 8, referring to Fig. 4 explanation.

As shown in Figure 2, front bearing 5 height, lower than rear support 6, make screen cloth become 30 °-45° angle with horizontal plane, and enrockment relies on deadweight along screen cloth landing, because angle is excessive, does not cause enrockment landing fast simultaneously, and screening effect is poor.Spring 7 is arranged on the junction of each screen cloth and bearing, slows down the impact of enrockment to bearing, extension fixture service life; Spring is used the vibrations that produce the little amplitude of low frequency simultaneously, is conducive to reduce the probability of card stone.

As shown in Figure 3, framework 2 equal intervals are arranged embedded hole 12, and aperture is slightly larger than the diameter of net bar, for also free to rotate in net bar 8 embedding frameworks 2, and the rotation of enrockment landing drive net bar, and then promote enrockment landing, minimizing to block the generation of stone phenomenon.

As shown in Figure 4, net bar 8 is solid steel rider, and steel rider is cylindrical, and wearability is good, and enrockment is easy to landing on screen cloth.Net bar 8 one end can update bar 9, and the action bars body of rod is mutually vertical with handle, is easy to grasp and the application of force.While there is card stone phenomenon, action bars 9 is inserted in net bar 8 and use nut 11 fixing, rotating operation bar drives the rotation of net bar, makes enrockment landing.The net bar 8 equal welded end plate 10 in two ends are to fix its position in framework 2.

During use, by excavator, stockpile is placed on screen cloth 1, while sieving, particle diameter stone not up to standard is screened out by mesh 4, falls into the sieve end, and bulk enrockment relies on deadweight to slide and drop on before screening plant along screen cloth 1, then concentrates and piles into stock ground.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model within spirit of the present utility model and principle.
