Description

Grit conveyor suitable for concrete mixing plant

Technical Field

The utility model belongs to concrete production equipment field, in particular to grit conveyor suitable for concrete mixing plant.

Background

At present, aggregate is often conveyed into a mixer in proportion by a conveyor belt conveying mode in a material conveying system of a concrete mixing plant for mixing. The conveying belt has the advantages of large conveying distance, high efficiency and low failure rate, and effectively shortens the charging time of the stirrer. However, as the density of the sand is high, when the sand directly falls onto the conveying equipment from the sand filtering device, the sand continuously impacts the feed end part of the conveying belt, so that the service life of the conveying belt is influenced; and when the sand falls on the conveyer belt from a high position or the sand is heavy, the carrier roller is easy to damage, so that the sand conveyer belt can not keep good and stable operation.

CN205802205U discloses a grit conveyor, includes the frame, installs a plurality of drive shafts in the frame and overlaps the conveyer belt that is used for carrying the grit in the drive shaft, be equipped with a plurality of crashproof pieces on the conveyer belt, crashproof piece fixed mounting is located the region that the grit dropped on the conveyer belt surface, the conveyer belt surface still is equipped with a plurality of guide pillars, the guide pillar is the symmetry and sets up fixed mounting and forms concave type dish in crashproof piece both sides. The device improves through carrying out improvement to conveyer belt itself, improves the life of conveyer belt. But need carry out special processing to the conveyer belt, the processing degree of difficulty is great, still exists the damage to conveying equipment's bearing roller moreover.

Disclosure of Invention

The utility model aims to solve the technical problem that a grit conveyor suitable for concrete mixing plant is provided, improve conveying equipment's life, processing is easy.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a grit conveyor suitable for concrete mixing plant, includes band conveyer, be equipped with buffer gear in the frame of band conveyer's pan feeding end, buffer gear includes the supporting leg of being connected with band conveyer's frame, is equipped with the buffer board on the supporting leg, and the one end that the buffer board is close to band conveyer's feed end is higher than the other end.

In a preferred scheme, the buffer plate is of an arc-shaped structure.

In a preferable scheme, a material stopping plate is arranged at the higher end of the buffer plate.

In the preferred scheme, the supporting leg includes the sleeve and sets up the connecting rod in the sleeve, is equipped with the limiting plate on the connecting rod, is equipped with the spring between limiting plate and the telescopic top.

In a preferable scheme, a vibration motor is arranged at the bottom of the buffer plate.

In the preferred scheme, the machine frames on two sides of the belt conveyor are provided with material baffle plates.

The utility model provides a pair of grit conveyor suitable for concrete mixing plant through setting up buffer gear, can be to the grit that falls into on the band conveyer at first fall into the buffer board landing on the conveyer belt again, effectively cushion the whereabouts of grit, reduces the damage to conveyer belt and band conveyer's bearing roller, improves band conveyer's life. Preferably, set up the buffer board into the arc structure, can block the grit of whereabouts on the one hand, fall into the buffer board outside when preventing the grit whereabouts, on the other hand, the grit falls into the central point of buffer board along the cambered surface of arc structure and puts, plays the effect of gathering together to the grit.

Drawings

The invention will be further explained with reference to the following figures and examples:

fig. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a cross-sectional view of a cushioning mechanism;

FIG. 3 is a schematic view of a preferred cushioning mechanism;

in the figure: band conveyer 1, supporting leg 2, buffer board 3, striker plate 4, vibrating motor 5, striker plate 6, sleeve 201, connecting rod 202, limiting plate 203, spring 204.

Detailed Description

Example 1: as shown in figures 1-2, a grit conveyor suitable for concrete mixing plant, includes band conveyer 1, be equipped with buffer gear in the frame of band conveyer 1's pan feeding end, buffer gear includes supporting leg 2 of being connected with band conveyer 1's frame, is equipped with buffer board 3 on the supporting leg 2, and the one end that buffer board 3 is close to band conveyer 1's feed end is higher than the other end.

When the sand filtering device is used specifically, sand discharged from the sand filtering device or the grading equipment falls onto the buffer plate 3, is buffered by the buffer plate 3 and then falls onto the conveying belt of the belt conveyor 1, and is conveyed to the next procedure. The impact force of the sand on the conveying belt is reduced through the buffer plate 3,

preferably, as shown in fig. 2, the buffer plate 3 has an arc-shaped structure. Set up buffer board 3 into the arc structure, can block the grit of whereabouts on the one hand, fall into the 3 outsides of buffer board when preventing the grit whereabouts, on the other hand, the grit falls into buffer board 3's central point along the cambered surface of arc structure and puts, plays the effect of gathering together to the grit.

Preferably, a material stopping plate 4 is arranged at the higher end of the buffer plate 3. Set up the material stopping plate 4 and carry out the shutoff to the tip of buffer board 3, prevent that the grit from the tip departure.

Preferably, the machine frames on two sides of the belt conveyor 1 are provided with material baffle plates 6. Can prevent through setting up striker plate 6 that band conveyer 1 from carrying the time of grit, the grit drops from conveyor belt's both sides.

Example 2: different from embodiment 1, as shown in fig. 3, the support leg 2 includes a sleeve 201 and a connecting rod 202 disposed in the sleeve 201, the lower end of the sleeve 201 is connected to the frame of the belt conveyor 1, the connecting rod 202 is connected to the buffer plate 3, a limiting plate 203 is disposed on the connecting rod 202, and a spring 204 is disposed between the limiting plate 203 and the top of the sleeve 201.

Through with connecting rod 202 slidable mounting in sleeve 201 to through spring 204's combined action, when making the grit fall into on buffer board 3, buffer board 3 can reciprocate, thereby can realize effectual buffering, reduces the vibration conduction to band conveyer 1 and to the impact force of buffer board 3.

Preferably, the bottom of the buffer plate 2 is provided with a vibration motor 5. When the gravel humidity is large, the buffer plate 3 vibrates up and down by starting the vibration motor 5, which is beneficial to the sliding of the gravel.
