Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It is to be understood that the preferred embodiments described herein are for purposes of illustration and understanding only and are not intended to limit the invention.

Embodiment is applied to feeding storehouse on coal breaker

As shown in fig. 1 to 2, the present embodiment includes a feeding bin body 1, a conveying mechanism fixed on one side of the feeding bin body 1, and a vibrating screen and a splash-proof mechanism fixed in a material cavity of the feeding bin; wherein, can dismantle between the screen cloth 2 of shale shaker and the feeding storehouse inner wall and be connected. The embodiment can enable the coal crusher to get rid of the limitation of the screen 2 to the coal crusher, and the screen 2 with different specifications can be replaced according to the use requirements of customers, so that the application range of the coal crusher is wider; on the other hand, in the working process, the anti-splashing mechanism can prevent coal from splashing from the hammer breaking mechanism, so that the device is safer and more reliable to use.

First, feeding storehouse body 1

When the device works, the feeding bin body 1 is used for directly screening out small coal meeting the specification in the large raw coal and delivering the rest large coal to the hammer crushing mechanism. The basic structure of the feeding bin body 1 is the same as that of a feeding bin in the prior art, namely, the upper end part of the feeding bin body 1 is a feeding hole, the lower end part of the feeding bin body is a first discharging hole, and a material cavity is formed between the feeding hole and the first discharging hole.

As shown in fig. 1, a second discharge port is further formed in one side surface of the feeding bin body 1, the feeding bin body 1 is communicated with a hammering mechanism of the coal crusher through the second discharge port, and large coal on the screen mesh 2 is thrown into the hammering mechanism through the second discharge port. And the position of the second discharge port is provided with an anti-splashing mechanism so as to prevent coal from splashing from the hammer breaking mechanism when the hammer breaking mechanism works. In this embodiment, the anti-spattering mechanism is a plurality of groups of closely arranged chains 3, and each group of chains 3 is fixedly arranged at the top end of the second discharge hole and extends downwards to the bottom end of the second discharge hole. When specifically arranging, select the chain 3 quantity of using according to the size of second discharge gate, can shelter from the second discharge gate completely through chain 3 promptly.

And a vibrating screen is arranged in the material cavity of the feeding bin and used for directly screening out small coal which meets the specification in the large raw material coal in advance. The vibrating screen comprises a vibrating motor fixedly arranged on the outer wall of the material cavity and a screen 2 which is detachably connected with the inner wall of the material cavity and completely covers the first discharge hole. The vibrator in the vibrating motor is an eccentric wheel, and the vibrator is driven by the motor to rotate so that the side wall of the material cavity shakes, and the screen 2 vibrates. The screen 2 is obliquely fixed in the material cavity, as shown in fig. 1, one end of the screen 2 is arranged at the bottom end of the second discharge hole, and the other end is relatively higher and is basically positioned at the same horizontal plane with the feed hole.

As shown in fig. 2, the two sides of the screen 2 are welded with a plurality of fixing blocks 6, the inner wall of the material cavity is provided with fixing clamping grooves 4 matched with the fixing blocks 6, and the screen 2 is detachably fixed on the inner wall of the material cavity through the mutual matching of the fixing blocks 6 and the fixing clamping grooves 4. As shown in fig. 1, three fixing blocks 6 are fixedly arranged on two sides of the screen 2 at equal intervals in the embodiment, three fixing slots 4 are correspondingly arranged on the inner wall of the material cavity, and the closer to the second discharge port, the lower the arrangement position of the fixing slot 4 is, so as to realize the inclined fixation of the screen 2 in the material cavity. It should be noted that each fixing slot 4 extends to the feeding opening, so that the fixing block 6 is placed in the fixing slot 4. When the device is in operation, in order to prevent the fixed block 6 from separating from the fixed clamping groove 4, each fixed clamping groove 4 is L-shaped, and a blocking rod 5 is hinged to one side of the corner of the fixed clamping groove 4 and the inner wall of the material cavity.

Second, the transport mechanism

Transport mechanism is used for throwing in the material to the feeding storehouse, can avoid once only throwing in too much material to the material intracavity at the device during operation. Conveying mechanism sets up in one side of feeding storehouse body 1, and conveying mechanism includes material conveyer belt 7 and to the driving motor of material conveyer belt 7 transport power, and wherein the output of material conveyer belt 7 extends to feed inlet department.

And a transmission roller is fixed at one end of the material conveying belt 7 and is connected with the power output end of the driving motor through a transmission belt to provide power for the material conveying belt 7. In order to avoid the problem that the conveying efficiency of the material conveying belt 7 is low due to the fact that the materials to be conveyed are too heavy and too much, a driven roller is arranged at one end, which is not connected with the transmission roller, of the material conveying belt 7. The driven roller is in driving connection with the transmission roller through a transmission belt and rotates under the driving of the transmission roller, so that the auxiliary transmission roller drives the material transmission belt.

Third, the working process

This device and coal breaker formula structure as an organic whole, feeding storehouse body 1 is linked together through the discharging belt in first discharge gate and the coal breaker promptly, breaks the mechanism through the hammer in second discharge gate and the coal breaker and is linked together. When the coal mining device is used, the bulk raw coal is put on the material conveyor belt 7 through the forklift, and the bulk raw coal is gradually put into the feeding bin through the material conveyor belt 7; then a vibrating screen in the feeding bin works, large raw coal blocks are screened in the material cavity, and small coal blocks which are screened out by the screen 2 and meet the specification directly fall onto a discharging belt through a first discharging hole; and large coal which is not sieved out by the screen mesh 2 is thrown into the hammer breaking mechanism through a second discharge hole. The iron chain arranged at the second discharge hole can prevent the coal in the hammer breaking mechanism from splashing out on the premise of not influencing the forward movement of the large coal entering the hammer breaking mechanism.

When the screen 2 needs to be replaced, the blocking rod 5 is rotated firstly, so that the blocking rod 5 is far away from the fixed clamping groove 4, and then the whole screen 2 is taken out of the material cavity; and the screen 2 to be replaced is fixed in the material cavity through the fixing block 6, and the blocking rod 5 is reset to complete the replacement of the screen 2.

It should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and the present invention is not limited thereto, and although the present invention has been described in detail with reference to the above-mentioned embodiments, it will be apparent to those skilled in the art that modifications can be made to the technical solutions described in the above-mentioned embodiments, or some technical features can be replaced with equivalents. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
