Description

Grit unloader

Technical Field

The application relates to the technical field of grit unloader, especially relates to a grit unloader.

Background

With the continuous development and progress of economic construction and the acceleration of urbanization process in China, urban infrastructure and real estate development in China are developed rapidly, and meanwhile, the rapid improvement of the yield of concrete is promoted.

In the process of producing concrete, a plurality of materials need to be prepared and mixed after being accurately weighed. The commonly used batching mode is a belt batching mode, and the structure of the belt batching mode is sequentially provided with a sand and stone discharging hopper, a weighing hopper and a sand and stone conveying belt from top to bottom. When the sandstone is used for batching, the natural sandstone is poured into the sandstone discharging hopper, then the natural sandstone is weighed through the weighing hopper, and finally, the sandstone is conveyed to the production equipment through the sandstone conveying belt for concrete batching.

However, natural sandstone farms are mostly produced by using natural raw materials of river channels or beaches, and the natural raw materials have a lot of uncertainty, such as large mud content, large water content, more ultrapath stones and the like. In the process of pouring the sandstone into the sandstone discharging hopper, a mudstone mixture often appears, and the mudstone mixture is adhered to the sandstone discharging hopper due to high mud content and water content, so that the discharging of the sandstone discharging hopper is influenced, and the feeding speed is reduced; and the falling process of the ultradiameter stone breaks a receiving belt or blocks a feed inlet due to large volume and heavy weight.

To the correlation technique among the above-mentioned, the inventor thinks great grit can block up the discharge gate of hopper under the grit at the in-process of feeding, and then influences the unloading efficiency of hopper under the grit.

SUMMERY OF THE UTILITY MODEL

In order to improve the unloading efficiency of hopper under the grit, this application provides a grit unloader.

The application provides a grit unloader adopts following technical scheme:

the utility model provides a grit unloader, is including burying the unloading mechanism under subaerial grit hopper and on being located the grit hopper, unloading mechanism includes the support frame, is located first screen cloth and two at least on the support frame can be right the support frame carries out the support column that supports, set up subaerial in one side of support frame, the opposite side by the support of support column, the one end of support column with the support frame is connected, and the other end is placed hopper and subaerial junction under the grit.

Through adopting above-mentioned technical scheme, during the use, utilize the forklift to fall the grit on first screen cloth, the grit can be along with gravity whereabouts, but grit and the impurity that hardens in the grit can be blockked by first screen cloth, and the grit that the messenger can pass through first screen cloth falls into the grit smoothly and hopper down. Through first screen cloth, can sieve the grit, make the grit that meets the requirements get into the grit hopper down, reduce the grit that hardens and cause the jam to the feed inlet of grit hopper down, and then improve the unloading efficiency of grit hopper down.

Optionally, a vibration motor is arranged on the first screen.

By adopting the technical scheme, when too much gravel is accumulated on the first screen, the vibrating motor is adjusted, the driving shaft of the vibrating motor drives the vibrating motor to vibrate, the vibrating motor drives the first screen to shake, and then hardened gravel is decomposed, so that the gravel capable of passing through the first screen falls and enters the gravel discharging hopper; the grit and the residue that are difficult to be decomposed are vibrated to one side by first screen cloth, and then reduce the jam of first screen cloth, make the grit that can pass through first screen cloth get into the grit hopper. The vibrating motor who sets up can drive first screen cloth as required and vibrate, and then reduces the grit and take place to block up, improves the unloading efficiency of grit.

Optionally, at least two inclined struts are arranged on the support frame, one ends of the inclined struts are connected with the bottom of the support frame, and the other ends of the inclined struts are arranged at the joint of the gravel discharging hopper and the ground.

Through adopting above-mentioned technical scheme, the bracing of setting can strengthen the stability of support frame, makes the support frame carry out stable support to first screen cloth, reduces the support frame and takes place the slope, and then causes the grit to directly fall into the grit hopper under the grit, and then causes the jam of grit hopper under the grit, influences the unloading speed of hopper under the grit.

Optionally, the support frame is arranged obliquely.

Through adopting above-mentioned technical scheme, when the grit that is difficult to decompose was blockked by first screen cloth, grit and residue can fall along the wire side roll of first screen cloth, reduce the possibility that first screen cloth blockked up, and then can improve the unloading efficiency of grit, in the grit gets into the grit fast and expects down. Simultaneously, the grit that rolls along a direction of first screen cloth rolls, and rolls and pile, and the staff of being convenient for concentrates the collection to the grit, reduces the work load of retrieving the grit that hardens, improves recovery efficiency.

Optionally, a second screen is paved on the feed inlet of the sand discharging hopper.

By adopting the technical scheme, when the hardened sand and stone pass through the first screen, the hardened sand and stone meet the second screen, and the hardened sand and stone are decomposed again under the action of gravity, so that the sand and stone can conveniently enter the sand and stone discharging hopper; simultaneously, when first screen cloth damaged, the second screen cloth can continue to sieve the grit, reduces the grit that hardens and in impurity gets into the grit hopper down, and then reduces the possibility of the jam of hopper under the grit, and then improves grit unloading efficiency.

Optionally, a reinforcing rib is arranged in the sand discharging hopper.

By adopting the technical scheme, the arranged reinforcing ribs can divide the feed inlet of the gravel discharging hopper into a plurality of subareas, so that the connecting strength of the two opposite sides of the gravel discharging hopper can be enhanced, the pressure on the two opposite sides of the gravel discharging hopper can be balanced, and the stress caused by gravel can be reduced; simultaneously, through the shutoff door of adjusting the grit hopper below, can control the unloading speed of hopper under the grit as required.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the sand and stone can be screened through the first screen, so that the sand and stone meeting the requirements enter the sand and stone discharging hopper, the blockage of the hardened sand and stone to the feeding hole of the sand and stone discharging hopper is reduced, and the discharging efficiency of the sand and stone discharging hopper is improved;

2. the support frame is obliquely arranged, so that sand and residues which cannot pass through the first screen mesh roll down along the mesh surface of the first screen mesh, and blockage of the sand and the first screen mesh by the sand is reduced; simultaneously, the grit that rolls can roll along the slope of first screen cloth and fall, and roll and pile, and the staff of being convenient for concentrates the grit and collects, reduces the work load of retrieving the grit that hardens, improves the recovery efficiency of grit.
