Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

1 to 4, a coal silo feeding device according to an embodiment of the present invention comprises: a coal silo body 1, a transmission seat 2 is arranged above the coal silo body 1; a transmission roller 3, two transmission rollers 3 are arranged, and are rotatably arranged inside the transmission seat 2 respectively, one end of the transmission roller 3 is connected to the output end of the external motor, and the two transmission rollers 3 are connected and transmitted through a conveyor belt 301; the upper opening of the coal silo body 1 corresponds to the transmission direction of the conveyor belt 301; a scraping mechanism, the scraping mechanism is arranged inside the transmission seat 2, and the scraping mechanism is used to scrape the coal material adhered to the surface of the conveyor belt 301; a dispersing mechanism, the dispersing mechanism is arranged inside the transmission seat 2, and the dispersing mechanism is used to disperse the coal material partially compacted on the surface of the conveyor belt 301;

During operation, when it is necessary to transport coal into the coal silo main body 1, the coal is first transported to the bottom end of the conveyor belt 301 through external equipment, and then the transmission roller 3 and the conveyor belt 301 are driven to rotate by the motor, so that the conveyor belt 301 drives the coal to be transported to the inside of the coal silo main body 1, and in the process of conveying the coal, the scraping mechanism can be used to scrape off part of the coal adhering to the surface of the conveyor belt 301, so as to avoid the problem that the coal adhering to the surface of the conveyor belt 301 does not completely fall into the coal silo during the conveying process, resulting in the subsequent coal falling outside the coal silo; and the dispersion mechanism can disperse part of the compacted coal, so as to avoid the problem that the compacted coal increases the oxidation rate of coal and causes spontaneous combustion.

The scraping mechanism includes a round shaft 4 fixedly installed inside the transmission seat 2, and a guide frame 5 is rotatably installed on the outer circumference of the round shaft 4. The guide frame 5 is inclined and arranged at the opening above the coal silo body 1. A scraper 6 is fixedly installed above the guide frame 5. The surface of the scraper 6 contacts the outer surface of the conveyor belt 301, and the width of the scraper 6 is adapted to the width of the conveyor belt 301.

During operation, when the conveyor belt 301 is conveying coal, most of the coal will directly fall into the coal silo, while a small amount of coal with greater adhesion will adhere to the surface of the conveyor belt 301;

Therefore, during the process of coal transportation by the conveyor belt 301, the end of the scraper 6 is always in contact with the surface of the conveyor belt 301. Therefore, during the rotation of the conveyor belt 301, the scraper 6 will scrape off the sticky coal on the surface of the conveyor belt 301. Then, under the action of the inclined guide frame 5, the coal will slide along the guide frame 5 to the inside of the coal silo body 1. As shown in Figures 3 and 4, the scraper 6 is positioned above the opening of the coal silo body 1. Therefore, the coal can completely fall into the inside of the coal silo body 1 and will not fall outside the coal silo body 1. The operation is relatively convenient.

Referring to FIGS. 2 to 9 , a transverse shaft 7 is fixedly installed at both ends of one group of the transmission rollers 3, a rotating shaft 8 is rotatably installed inside the transmission seat 2, the transverse shaft 7 and the ends of the rotating shaft 8 are connected by a belt 9, a cam 10 is fixedly installed on the outer circumference of the rotating shaft 8, and during the rotation of the cam 10, the protrusion on the surface of the cam 10 will intermittently contact the side wall of the guide frame 5, and a torsion spring 12 is provided at the contact position between the inner wall of the guide frame 5 and the circular shaft 4;

During operation, when the transmission roller 3 rotates, the transmission roller 3 will simultaneously drive the horizontal shaft 7 to rotate, and the horizontal shaft 7 will drive the rotating shaft 8 to rotate through the belt 9, and the rotating shaft 8 will drive the cam 10 to rotate. During the rotation process, the protrusions on the surface of the cam 10 will contact and squeeze the surface of the guide frame 5, so that the guide frame 5 rotates at a certain angle on the outer surface of the circular shaft 4, so that the contact friction between the scraper 6 on the surface of the guide frame 5 and the surface of the conveyor belt 301 is increased, thereby improving the scraping effect of the bonded coal material;

Moreover, when the guide frame 5 rotates on the surface of the circular shaft 4, it will simultaneously drive the torsion spring 12 to contract to a certain extent. When the cam 10 is separated from the guide frame 5, the guide frame 5 will vibrate to a certain extent under the elastic force of the torsion spring 12, so that the coal on the surface of the guide frame 5 can fall into the coal silo as soon as possible, thereby accelerating the feeding of the coal.

5 to 11 , the guide frame 5 is composed of a positioning frame 501 and a compression frame 502. The positioning frame 501 is rotatably mounted on the outer circumference of the circular shaft 4, the compression frame 502 is slidably mounted on the top of the positioning frame 501, the scraper 6 is fixedly mounted on the top of the compression frame 502, the side wall of the positioning frame 501 is mounted with a compression spring 504, and the side wall of the compression frame 502 is connected to one end of the compression spring 504;

During operation, when the cam 10 rotates, the cam 10 will contact the surface of the positioning frame 501. When the top of the scraper 6 is subjected to the surface pressure of the conveyor belt 301, the compression frame 502 connected to the scraper 6 will be compressed and squeeze the compression spring 504, and move a certain distance outside the positioning frame 501; when the cam 10 is separated from the positioning frame 501, under the action of the compression spring 504, the compression frame 502 will recover, so that the compression frame 502 can move up and down outside the positioning frame 501, so that the coal on the surface of the positioning frame 501 can fall into the coal silo as soon as possible.

The two side walls of the positioning frame 501 are provided with limiting grooves 13, a telescopic rod is installed inside the limiting groove 13, the compression spring 504 is sleeved on the outer surface of the telescopic end of the telescopic rod, the inner wall of the compression frame 502 is installed with a limiting block 503, the compression frame 502 is slidably installed inside the limiting groove 13 through the limiting block 503, the shape of the limiting block 503 is adapted to the shape of the limiting groove 13, the end of the compression spring 504 is in contact with the lower side wall of the limiting block 503, the inside of the transmission seat 2 is fixedly installed with a limiting frame 14 through a side bracket, two limiting frames 14 are provided, and the tops of the two limiting frames 14 are respectively in contact with the lower side wall of the positioning frame 501 When the compression frame 502 is working, it moves up and down on the outer side of the positioning frame 501, and the compression frame 502 will simultaneously drive the limit block 503 on its inner wall to move, and the limit block 503 will move inside the limit groove 13, and the limit block 503 will squeeze the compression spring 504 inside the limit groove 13 when moving down; when the contact pressure between the top of the scraper 6 and the conveyor belt 301 is reduced, under the action of the compression spring 504, the compression frame 502 will move up on the outer side of the positioning frame 501, so that under the mutual limitation of the limit block 503 and the limit groove 13, the compression frame 502 can be conveniently moved up and down on the outer side of the positioning frame 501, and the coal material adhering to the surface of the positioning frame 501 can be scraped off as soon as possible;

When the protrusion of the cam 10 is separated from the positioning frame 501, under the elastic force of the torsion spring 12, the positioning frame 501 and the compression frame 502 will be driven to quickly return to the initial position, that is, to return to the side close to the rotating shaft 8. When it rotates, the limit frame 14 on the lower side wall of the positioning frame 501 will limit the recovery angle of the positioning frame 501, that is, to avoid the positioning frame 501 from recovering too much, resulting in the positioning frame 501 and the compression frame 502 and the scraper 6 at the top being away from the surface of the conveyor belt 301, that is, the scraper 6 can always be in contact with the surface of the conveyor belt 301.

5 to 16, the dispersion mechanism includes a support frame 15 slidably mounted inside the transmission seat 2, a support spring is installed at the contact position between the support frame 15 and the transmission seat 2, a plurality of swing rods 16 are installed on the outer surface of the support frame 15, and the plurality of swing rods 16 are arranged at equal distances on the outer surface of the support frame 15, and the ends of the plurality of swing rods 16 away from the support frame 15 are in contact with the surface of the conveyor belt 301;

During operation, as shown in FIG. 8 , the swing rod 16 is located on the surface of the conveyor belt 301. When the conveyor belt 301 is transporting coal, the swing rod 16 will disperse the coal on the surface of the conveyor belt 301, thereby dispersing some of the coal that is piled higher, which is beneficial to the subsequent transportation of the coal.

7 to 9, the side surface of the support frame 15 is provided with a plurality of circular grooves, each of which is provided with a crushing rod 17, the bottom of which is conical, and a cylinder 18 is rotatably provided on one side of the transmission seat 2 close to the support frame 15, and a rotating shaft 2 19 is fixedly provided at both ends of the cylinder 18, the rotating shaft 2 19 and the horizontal axis 7 are connected by a belt 2 20, and a plurality of arc-shaped pressing plates 21 are fixedly provided on the outer circumference of the cylinder 18, and the arc-shaped pressing plates 21 are in contact with the upper end surface of the support frame 15 when the cylinder 18 drives the arc-shaped pressing plates 21 to rotate;

During operation, when the horizontal axis 7 rotates, the belt 20 causes the rotating shaft 19 to rotate at the same time, and the rotating shaft 19 drives the cylinder 18 to rotate, and the cylinder 18 drives the arc-shaped pressure plate 21 on its surface to rotate. The arc-shaped pressure plate 21 presses down the support frame 15 during rotation, and the support frame 15 drives the crushing rod 17 to move downward. When the crushing rod 17 moves downward, some of the more compacted coal will be crushed, and with the subsequent dispersion of the coal by the swing rod 16, the problem of coal spontaneous combustion can be avoided because the oxidation rate of coal will increase during compaction, which may cause serious problems.

It should be noted that there is a margin for movement of the support frame 15 between the bottom of the swing rod 16 and the surface of the conveyor belt 301, so as to facilitate the dispersion and transmission of the coal.

8 to 16, a limiting cylinder 22 is fixedly installed inside the support frame 15 and in the circular groove, the crushing rod 17 is arranged inside the limiting cylinder 22, and a limiting groove 23 is provided on the inner wall of the limiting cylinder 22. An elastic arc head 24 is fixedly installed on the side wall of the crushing rod 17, and the elastic arc head 24 is stuck in the limiting groove 23. A contact 1 25 is fixedly installed on the side wall of the crushing rod 17, and a contact 2 26 is installed at a position corresponding to the inner wall of the limiting cylinder 22 and the contact 1 25, and a reset spring is sleeved on the outer peripheral surface of the crushing rod 17;

During operation, in the initial state, the elastic arc head 24 is located inside the limiting groove 23, and the contact 1 25 and the contact 2 26 are not in contact; if the compaction of the transmitted coal is too large, that is, the pressure on the crushing rod 17 when moving downward is too large, the crushing rod 17 will drive the elastic arc head 24 to break away from the limiting groove 23, and the crushing rod 17 will drive the contact 1 25 to move to the side close to the contact 2 26, and then the contact 1 25 and the contact 2 26 will contact. At this time, the external controller will control the alarm to sound an alarm to remind the staff that the compaction of the transmitted coal is too large, and to process the coal to facilitate the use of the coal;

When the arc pressure plate 21 is separated from the support frame 15, under the action of the support spring, the support frame 15 will return to its initial position, so that the dispersion effect of the coal can be further improved under the reciprocating movement of the support frame 15; and if the elastic arc head 24 is detached from the inside of the limiting groove 23 and the support frame 15 is restored again, the contact 1 25 and the contact 2 26 will be separated, and under the elastic force of the reset spring on the outside of the crushing rod 17, the crushing rod 17 will return to its initial position, and the elastic arc head 24 will slowly enter the inside of the limiting groove 23, which is convenient for the subsequent monitoring of the coal and has high safety.

A placement groove is provided inside each of the swing rods 16, and an elastic ball 27 is placed inside the placement groove. Each of the swing rods 16 is rotatably mounted on the outer surface of the support frame 15, and a limit bracket is provided at the surface of the support frame 15 and the rotation position of the swing rod 16. During operation, since the swing rod 16 is rotatably set on the surface of the support frame 15, and when the support frame 15 moves up and down, the elastic ball 27 inside the swing rod 16 will move disorderly, and this disordered movement includes movement in the horizontal direction, which will drive the swing rod 16 to swing horizontally with a certain amplitude, thereby further dispersing the coal, which is beneficial to its storage and reuse.

The surface of the limiting groove 23 is provided with rounded corners, the shape of the elastic arc head 24 is adapted to the shape of the limiting groove 23, and the outer surface of the elastic arc head 24 is sleeved with a spring; during operation, such a design can facilitate the elastic arc head 24 to be stuck inside the limiting groove 23, thereby facilitating the monitoring of the compaction degree of the coal material and improving the safety of coal material transportation.

During operation: during the conveyor belt 301 conveying the coal, most of the coal will directly fall into the coal silo, while a small amount of coal with greater adhesion will adhere to the surface of the conveyor belt 301;

Therefore, during the coal transportation process of the conveyor belt 301, the end of the scraper 6 is always in contact with the surface of the conveyor belt 301. Therefore, during the rotation of the conveyor belt 301, the position of the scraper 6 remains unchanged, and the coal adhering to the surface of the conveyor belt 301 is scraped off. Then, under the action of the inclined guide frame 5, the coal slides along the guide frame 5 into the coal silo body 1. As shown in FIGS. 3 and 4, the position of the scraper 6 is above the opening of the coal silo body 1, so the coal can fall completely into the coal silo body 1 without falling off. It falls outside the coal silo body 1, which is convenient to operate; when the transmission roller 3 rotates, the transmission roller 3 will simultaneously drive the horizontal shaft 7 to rotate, and the horizontal shaft 7 will drive the rotating shaft 8 to rotate through the belt 9, and the rotating shaft 8 will drive the cam 10 to rotate. During the rotation process, the cam 10 will contact and squeeze the surface of the guide frame 5, so that the guide frame 5 rotates at a certain angle on the outer surface of the circular shaft 4, so that the contact friction between the scraper 6 on the surface of the guide frame 5 and the surface of the conveyor belt 301 is increased, thereby improving the scraping effect of the bonded coal material;

Moreover, when the guide frame 5 rotates on the surface of the circular shaft 4, it will simultaneously drive the torsion spring 12 to contract to a certain extent. When the cam 10 is separated from the guide frame 5, under the elastic force of the torsion spring 12, the guide frame 5 will vibrate to a certain extent, so that the coal on the surface of the guide frame 5 can fall into the coal silo as soon as possible, thereby accelerating the feeding of the coal. When the compression frame 502 moves up and down on the outer side of the positioning frame 501, the compression frame 502 will simultaneously drive the limit block 503 on its inner wall to move, and the limit block 503 will The compression frame 502 moves inside the limiting groove 13, and the limiting block 503 squeezes the compression spring 504 inside the limiting groove 13 when moving downward; when the contact pressure between the top of the scraper 6 and the conveyor belt 301 decreases, under the action of the compression spring 504, the compression frame 502 moves upward on the outside of the positioning frame 501, so that under the mutual limitation of the limiting block 503 and the limiting groove 13, the compression frame 502 can be easily moved up and down on the outside of the positioning frame 501, and the coal material adhering to the surface of the positioning frame 501 can be scraped off as soon as possible;

When the protrusion of the cam 10 is separated from the positioning frame 501, the elastic force of the torsion spring 12 will drive the positioning frame 501 and the compression frame 502 to quickly return to the initial position, that is, to return to the side close to the rotating shaft 8. When it rotates, the limit frame 14 on the lower side wall of the positioning frame 501 will limit the recovery angle of the positioning frame 501, that is, to avoid the positioning frame 501 from recovering too much, resulting in the positioning frame 501 and the compression frame 502 and the scraper 6 at the top being away from the surface of the conveyor belt 301, that is, the scraper 6 can always be in contact with the surface of the conveyor belt 301.

When the horizontal axis 7 rotates, the belt 20 causes the rotating shaft 2 19 to rotate at the same time, and the rotating shaft 2 19 will drive the cylinder 18 to rotate, and the cylinder 18 will drive the arc-shaped pressure plate 21 on its surface to rotate. The arc-shaped pressure plate 21 will press down the support frame 15 during the rotation, and the support frame 15 will drive the crushing rod 17 to move downward. When the crushing rod 17 moves downward, some of the more compacted coal will be crushed, and under the subsequent dispersion of the coal by the swing rod 16, it can avoid the problem of coal spontaneous combustion caused by the increase of the oxidation rate of coal during compaction, which may cause serious problems. In the initial state, the elastic arc head 24 is located inside the limiting groove 23, and the contact 1 25 and the contact 2 26 are not in contact. If the compaction of the transmitted coal is too large, that is, the pressure on the crushing rod 17 when it moves downward is too large, the crushing rod 17 will drive the elastic arc head 24 from the inside of the limiting groove 23 When the arc-shaped pressure plate 21 is separated from the support frame 15, the support frame 15 will return to its initial position under the action of the spring, so that the dispersion effect of the coal can be further improved under the reciprocating movement of the support frame 15; and when the elastic arc head 24 is separated from the inside of the limiting groove 23 and the support frame 15 is restored again, the contact 1 25 and the contact 2 26 will be separated, and under the self-gravity of the crushing rod 17, the elastic arc head 24 will slowly enter the inside of the limiting groove 23, which is convenient for the subsequent monitoring of the coal and has high safety.

Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
