Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

A mobile impact crushing station with a leak proof seal mechanism, as shown in fig. 1 and 2, comprising: the hollow main frame 1 is provided with an opening at the upper end. The top end of the main frame 1 is fixed with a crushing device 2, and the outer side wall of the main frame is fixedly provided with a crawler moving mechanism 3. The main frame 1 is internally provided with a conveying belt frame 4, a first sealing rubber plate 5, at least one group of two second sealing rubber plates 6 which are oppositely arranged, a chain sealing mechanism 7 and a rubber plate sealing mechanism. Be equipped with the conveyor belt on 4 frames of conveyor belt, the conveyor belt includes: a horizontal main transport section 401, and a side transport section 402 connected to both sides of the main transport section 401 and tilted upward. The outlet of the lower silo 201 of the crushing device 2 is opposite to the main transportation section 401. The chain sealing mechanism 7 and the rubber plate sealing mechanism are respectively and sequentially installed in the reverse front of the lower storage bin 201 along the transportation direction of the main transportation section 401.

First sealing rubber plate 5 sets up along main transportation section 401 axial, and on the vertical installation in feed bin 201 bottom face down in its top, the bottom just was equipped with the inclined plane with side transportation section 402 assorted with the contact of side transportation section 402. The second sealing rubber plate 6 is respectively located between the first sealing rubber plate 5 and two vertical inner walls of the main frame 1 along the axial direction of the main transportation section 401, and is fixedly installed between the lower storage bin 201 and the transportation belt frame 4 along the vertical direction.

The working process of the device is as follows: the crawler moving mechanism 3 is used for driving the main frame 1 and the crushing device 2 to move, and the crushing device 2 is used for crushing materials. The material crushed by the crushing device 2 falls into the main transportation section 401 from the feed opening of the feed bin 201, and is collected by the side transportation section 402 and is transported to a target position on the main transportation section 401. At this time, the fine particles and dust generated by crushing under the driving of the wind force are also flushed into the upper part of the conveyer belt frame 4 from the feed opening of the feed bin 201. The fine particles and dust that are rushed in are first confined and collected by the first sealing rubber sheet 5 onto the main transport section 401 and the side transport section 402. Because the lower end of the first sealing rubber plate 5 and the side conveying section 402 form a matching inclined plane, when the first sealing rubber plate 5 is pressed outwards and is squeezed, the lower end face of the first sealing rubber plate is contacted with the side conveying section 402 more tightly, and thus, two sides of the conveying belt frame 4 form a closed cavity. Meanwhile, the chain sealing mechanism 7 arranged in the reverse front of the main conveying section 401 in the conveying direction can effectively block large granular materials blown by wind power and moving reversely to the front of the blanking bin 201, and reduce the speed of the materials flowing reversely. The rubber sheet sealing mechanism forms a secondary seal to retain the counterflow material on the main 401 and side 402 transport sections for transport away on the main 401 and side 402 transport sections.

When the first sealing rubber sheet 5 is subjected to excessive pressure, the rubber sheet may be bent by stress to form a gap with the side transportation section 402, so that a part of the pressure is lost. At this time, the second sealing rubber plate 6 fixed between the lower bin 201 and the conveyor belt frame 4 forms a second airtight chamber for preventing the small particles and dust from leaking out.

Through research, the applicant only adopts the sealing rubber plate with the upper end and the lower end fixed, and the following problems exist: the sealing rubber plates are too close to each other, and if the sealing rubber plates are located at the position of the first sealing rubber plate 5, although the sealing rubber plates have a good bundling effect, the rubber plates cannot bear too large pressure, and the phenomenon of fracture is easy to occur under the pressure of wind power and materials. Too alternate segregation between the sealing rubber board, if be located second sealing rubber board 6 position department (do not install first sealing rubber board 5 additional), it is not good to receive the effect of restrainting, and a large amount of tiny particles and dust can be piled up outside side transportation section 402 and can not be carried away by the transportation belt, cause extravagant and increased later stage abluent work load. The sealing rubber plate which is fixed at the upper end and attached at the lower end is adopted, so that the following problems exist: too close to each other between the sealing rubber board, if be located 5 positions of first sealing rubber board when locating (do not install second sealing rubber board 6 additional), although there is the effect of restrainting, can carry out automatic pressure release when the rubber board bears too big pressure, the pressure release process can lead to some tiny particle and dust to leak certainly. Too alternate segregation between the sealing rubber board, if be located second sealing rubber board 6 position department (do not install first sealing rubber board 5 additional), it is not good to receive the effect of restrainting, and a large amount of tiny particles and dust can be piled up outside side transportation section 402 and can not be carried away by the transportation belt, cause extravagant and increased later stage abluent work load. The two-layer sealing rubber plate mechanism with the arrangement and the structure can better collect small particles and dust on the side edge and safely collect the small particles and the dust.

Example 2

Based on the mobile impact crushing station with the material leakage prevention sealing mechanism in embodiment 1, as shown in fig. 1, a buffer bed 403 is padded below the main transportation section 401, and a wear-resisting plate 404 is padded below the side transportation section 402. This arrangement protects the main 401 and side 402 transport sections from material impacts.

Example 3

Based on embodiment 1 the mobile impact crushing station with the material leakage preventing sealing mechanism, as shown in fig. 1, two sets of four angle steels 11 are symmetrically arranged between the first sealing rubber plate 5 and the main frame 1, wherein one set of two angle steels 11 are fixed at the bottom end of the lower bin 201 to form a first mounting groove, and the other set of two angle steels 11 are fixed at the top end of the conveying belt frame 4 to form a second mounting groove. The top end of the second sealing rubber plate 6 is inserted into the first mounting groove, and the bottom end of the second sealing rubber plate is inserted into the second mounting groove for fixing. This arrangement makes it possible to easily replace the second sealing rubber sheet 6 while ensuring that sufficient sealing is achieved.

Example 4

Based on the mobile impact crushing station with the material leakage prevention sealing mechanism in embodiment 1, as shown in fig. 1, the bottom end of the lower bin 201 is provided with a fixed baffle 12 in the vertical direction at a position above the side transportation section 402. The top end of the first sealing rubber plate 5 is fixed on the fixed baffle 12 through a screw. This arrangement makes it possible to easily replace the first sealing rubber sheet 5 while ensuring sufficient sealing.

Example 5

A gear 702 is rotatably installed between the adjacent vertical brackets 701. The gear 702 is engaged with a chain 703. The chain sealing mechanism with the structure can effectively block large particles through the chain 703, and meanwhile, the freely rotating gear 702 can drive the chain 703 to release part of materials into a second sealing cavity formed by the rubber plate sealing mechanism when the pressure is higher, so that the service life of the chain sealing mechanism 7 is prolonged, and particularly the service life of the vertical support 701 serving as a main pressure bearing member is prolonged.

Example 6

Based on the mobile impact crushing station with the material leakage prevention sealing mechanism in embodiment 1, as shown in fig. 2, the first sealing rubber plate 5 is a first preset distance away from the second sealing rubber plate 6, the first sealing rubber plate 5 extends outward a second preset distance relative to the chain sealing mechanism 7, and the second sealing rubber plate 6 extends outward a third preset distance relative to the first sealing rubber plate 5. The first preset distance is X/K1. The second preset distance is Y/K2. The second preset distance is Y/K3. X is the width of the feed opening of the feed bin 201, and Y is the length of the feed opening of the feed bin 201. The K1 takes the value of 10-30, the K2 takes the value of 30-50, and the K3 takes the value of 10-15. The values of K1, K2 and K3 are determined according to the rated wind power of the crushing device, and the larger the rated wind power is, the smaller the value is. Through the research of the applicant, the adoption of the preset distance can ensure that each sealed cavity can form enough sealing effect on one hand, and can reduce the size of each sealed cavity as much as possible on the other hand, thereby effectively controlling the whole size of the crushing station.

Example 7

And through disturbance and the obstruction that chain sealing mechanism 7 goes on the air current, the wind-force that first horizontal rubber seal board 8 itself need bear has been less greatly, consequently adopt the upper end fixed mode can, and the lower extreme adopts the mode of laminating, can make first horizontal rubber seal board 8 set up in main transportation section 401 and side transportation section 402 top, thereby the material that will block is transported away by main transportation section 401 and side transportation section 402 once more, thereby reduce the material loss, avoid the material to reveal to main transportation section 401 and side transportation section 402 outside. And through the secondary blocking of the first transverse rubber sealing plate 8, the pressure which needs to be borne by the second transverse rubber sealing plate 9 is smaller, so that the second transverse rubber sealing plate 9 can be compressed and fixed by adopting the spring compressing device 10, and meanwhile, the second transverse rubber sealing plate 9 can be manually lifted to carry out cleaning operation when needed.
