Description

Bulk cargo device

Technical Field

The utility model relates to a technical field is carried to the material, concretely relates to bulk cargo device.

Background

Bulk material devices are essential in bulk material conveying systems, i.e. intermediate links for transferring material from one apparatus to the next. Under the ordinary condition, a cylindrical guide chute is directly arranged between the two devices. However, for the screening of the vibrating screen, if the material entering the equipment can be fully distributed on the whole screen surface working width, the utilization rate and the screening efficiency of the screen are greatly improved, and the abrasion of the screen is correspondingly reduced. For air classification powder removing equipment, the material needs to be spread wide enough and thin enough, and the air can penetrate through the material flow to achieve the effect of classification powder removing. The solutions commonly adopted in the prior art mainly have three types: the first is to use a vibration feeder to slowly spread the materials in the vibration forward process; secondly, a partition plate is arranged in the chute to divide the material into a plurality of parts; and the third method is that an adjusting comb plate is arranged in the chute, and the material flow thickness is adjusted by adjusting the gap between the adjusting comb plate and the chute body. The first is that the middle part is thick and the two sides are thin in the bulk cargo process. When the feeding is concentrated, the discharging is concentrated, and the materials cannot be uniformly spread out to realize the purpose of bulk cargo.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a bulk cargo device with good bulk cargo effect and convenient adjustment.

The utility model adopts the technical proposal that:

the utility model provides a bulk cargo device, includes bulk cargo fill, pull apron and access door, the bulk cargo fill is two ladder type structures, the two ladder type structures of bulk cargo fill are arranged perpendicularly, the round hole of evenly arranging is seted up to the ladder board under the bulk cargo fill.

Furthermore, one side of the stepped plate under the bulk hopper is provided with a rectangular hole for the pulling cover plate to be flexibly pulled and inserted.

Further, a buffer plate is arranged between the lower stepped plate of the bulk hopper and the discharge port.

Further, cover all round holes of ladder board under the bulk cargo fill when the pull apron is inserted completely, do not shelter from arbitrary round hole when pulling out completely.

Compared with the prior art, the utility model has the advantages of: the bulk cargo device of the utility model can evenly spread the entering material flow under various working conditions, improve the feeding condition of the screening device and improve the screening efficiency; meanwhile, the utility model makes full use of the gravity of the material to effectively guide the material, and no external power is needed in the operation process, thereby saving the operation cost and energy consumption; in addition, the utility model discloses only need during the regulation with every rank pull apron pull to suitable position alright, light, convenient, swift, practiced thrift the adjust time.

Detailed Description

The invention is further described with reference to the following figures and detailed description.

As shown in fig. 1, fig. 2 and fig. 3, the bulk cargo device of the present invention comprises a bulk cargo hopper 1, a pull cover plate 2, a small access door 3 and a large access door 4, wherein the bulk cargo hopper 1 comprises an upper step plate 11, a lower step plate 12, a feed inlet 14 and a discharge outlet 15; the bulk material hopper 1 is of a double-step structure consisting of an upper step plate 11 and a lower step plate 12; the double-step structure of the bulk material hopper 1 is vertically arranged; the lower step plate 12 of the bulk material hopper 1 is provided with round holes 52 which are uniformly distributed.

Preferably, a rectangular hole 51 for flexibly inserting the pull-out cover plate 2 is formed on one side of the lower step plate 12 of the bulk bin 1.

Preferably, a buffer plate 13 is provided between the lower step plate 12 and the discharge port 15 of the bulk bin 1.

Preferably, the drawing cover plate 2 covers all the circular holes 52 of the lower step plate 12 of the bulk bin 1 when being completely inserted, and does not shield any circular hole 52 when being completely drawn out.

The materials 61 enter the bulk material hopper 1 from the feeding hole 14, the upper stepped plate 11 concentrates all the materials 61 entering the feeding hole 14 of the bulk material device, after the materials 61 are concentrated, all the materials 61 fall onto two uppermost steps of the lower stepped plate 12, and fall along the steps from the two uppermost steps, in the falling process, the through quantity of the materials 61 of each step of the lower stepped plate 12 is adjusted by covering partial circular holes 52 on the lower stepped plate 12 with the drawing cover plate 2, so that the materials 61 passing through each step of the lower stepped plate 12 are uniform, the materials 61 are uniformly dispersed when passing through the discharging hole 15, and the purpose of uniform bulk material distribution is achieved; and when the material 61 is provided with the buffer plate 13 between the lower stepped plate 12 and the discharge port 15, the falling kinetic energy of the material 61 is buffered, the falling speed is reduced, and the equipment below the discharge port 15 is fully protected.
