[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. After the coal is mined, a coal conveyor is needed to transport it out.

[0003] The existing (Announcement No.: CN219708232U) discloses a coal conveying device for coal mining, which is provided with a reciprocating component. During the coal conveying process, the continuously rotating cam causes the connecting arm to slide back and forth, thereby driving the fixed frame, so that the cleaning brush reciprocates on the surface of the conveyor belt, thereby improving the cleaning efficiency and preventing stubborn coal from being unable to be cleaned out.

[0004] Although the above patent can clean up the waste dust residue, there is often a lot of dust flying at the coal mining site, and it is not possible to achieve a good dust removal and dust prevention effect by simply relying on simple reciprocating cleaning and brushing. Utility Model Content

[0005] The purpose of the utility model is to provide a coal conveying device for coal mining, which solves the technical problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coal conveying device for coal mining, comprising a conveying shell, a conveying belt body for coal conveying is fixedly installed inside the conveying shell, an upper surface of one side of the conveying shell is connected to a feed shell fixedly installed inside, a side surface of the conveying shell away from the feed shell is connected to a discharge port, a discharge port is fixedly installed with a discharge guide plate that fits the conveying surface of the conveying belt body, an electric push rod is fixedly installed on the upper surface of the conveying shell, a sealing plug plate is fixedly connected to the push rod of the electric push rod, and a through groove for the sealing plug plate to be inserted and sealed is penetrated through the surface of one side of the feed shell;

[0007] The inner top wall of the conveying shell located at the position of the feeding shell is symmetrically installed with relative feeding guide plates and buffer guide plates of different lengths, and a dust head is embedded in the surface of one side of the conveying shell located at the unloading position between the feeding guide plate and the buffer guide plate, and a dust box is fixedly installed on the outer surface of one side of the conveying shell, a dust pipe is connected between the dust box and the dust head, and a filter is fixedly installed at the dust suction position of the dust head.

[0008] Optionally, a sliding rod is fixedly connected to a central lower surface of the sealing plug plate on a side close to the electric push rod, and a first sliding groove for sliding the sliding rod is provided on an upper surface of the conveying housing.

[0009] Optionally, the lower surface of the feed guide plate is in contact with the conveying surface on the other side of the conveyor belt body.

[0010] Optionally, a scraper frame is fixedly installed on the inner bottom wall of the conveying shell near the discharge port, and the scraper frame scrapes and fits on the conveying surface of the conveyor belt body. A collection box is slidably installed on one side of the scraper frame.

[0011] Optionally, the conveying shell is provided with a waste port below the discharge port, a rotating shaft plate is fixedly installed on the lower surface of the collecting box, a second slide groove is provided on the inner bottom wall of the conveying shell near the discharge port, a sliding seat is slidably connected inside the second slide groove, and the rotating shaft plate is rotatably connected inside the sliding seat.

[0012] Optionally, a waste baffle is fixedly connected to a surface of one side of the collecting box body close to the waste opening, and the waste baffle seals and slides inside the waste opening, and a handle is fixedly connected to the surface of the collecting box body.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model adopts the design of the conveying shell, which effectively achieves the purpose of isolating the coal entering the conveying shell for transportation from the external environment, thereby greatly reducing the situation where waste dust and residues adhere to the conveyor belt body and are difficult to clean, and improves the dust-proof effect of the coal conveying device.

[0015] 2. The utility model utilizes a sealing plug-in plate that is inserted and sealed in a through groove and driven by an electric push rod. When there is no need to use the conveying shell for coal mine transportation, the operator can start the electric push rod, and the push rod of the electric push rod drives the sealing plug-in plate to slide in the through groove until a sealing surface on one side of the sealing plug-in plate abuts against an inner wall surface of the feed shell, thereby avoiding the situation where dust falls through the feed shell and floats into the interior of the conveying shell when not in use, further ensuring the purpose of dust prevention.

[0016] 3. The utility model uses a dust collector head, a filter, a dust collector tube and a dust collector box in coordination. When the coal passes through the feed shell, enters the conveying shell and falls to the conveying surface of the conveyor belt body, the coal will produce tiny coal slag dust due to the collision with the material guide of the feed guide plate and the buffer guide plate. At this time, the dust collector head facing the feed guide plate and the buffer guide plate will, under the control of the dust collector box, perform dust removal through the dust collector tube. In addition, the filter not only has a filtering effect when vacuuming, but also avoids the phenomenon that larger coal slag enters the dust collector head and easily damages the machine, thereby further ensuring the efficient dust prevention effect of the coal conveying device.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] For example, see Figures 1 to 5The utility model provides a coal conveying device for coal mining, comprising a conveying shell 1, a conveying belt body 4 for coal conveying is fixedly installed inside the conveying shell 1, an upper surface of one side of the conveying shell 1 is connected to a feed shell 2 fixedly installed inside, a side surface of the conveying shell 1 away from the feed shell 2 is connected to a discharge port 3, a discharge port 3 is fixedly installed with a discharge guide plate 16 attached to the conveying surface of the conveying belt body 4, an electric push rod 7 is fixedly installed on the upper surface of the conveying shell 1, a sealing plug-in plate 8 is fixedly connected to the push rod of the electric push rod 7, and a side surface of the feed shell 2 is penetrated with a sealing through groove 9 for inserting the sealing plug-in plate 8;

[0025] The inner top wall of the conveying shell 1 located at the position of the feed shell 2 is symmetrically installed with relative feed guide plates 5 and buffer guide plates 6 of different lengths. The lower surface of the feed guide plate 5 is attached to the conveying surface on the other side of the conveyor belt body 4. A dust head 12 is embedded in the surface of one side of the conveying shell 1 at the unloading position between the feed guide plate 5 and the buffer guide plate 6. A dust box 15 is fixedly installed on the outer surface of one side of the conveying shell 1. A dust pipe 14 is connected between the dust box 15 and the dust head 12, and a filter 13 is fixedly installed at the dust suction position of the dust head 12.

[0026] More specifically, in this embodiment, the design of the conveying shell 1 effectively achieves the purpose of isolating the coal entering the conveying shell 1 for transportation from the external environment, thereby greatly reducing the situation where waste dust and residue adhere to the conveyor belt body 4 and are difficult to clean, thereby improving the dust prevention effect of the coal conveying device.

[0027] When the coal passes through the feed shell 2, enters the conveying shell 1 and falls to the conveying surface of the conveyor belt body 4, the coal will produce tiny coal slag dust due to the collision with the material guide of the feed guide plate 5 and the buffer guide plate 6. At this time, the dust suction head 12 facing the feed guide plate 5 and the buffer guide plate 6 will, under the control of the dust suction box 15, perform dust suction and dust removal through the dust suction pipe 14. In addition, the filter screen 13 not only has a filtering effect when vacuuming, but also avoids the phenomenon that larger coal slag enters the dust suction head 12 and easily damages the machine, thereby further ensuring the efficient dust prevention effect of the coal conveying device. Finally, through the transportation of the conveyor belt body 4 and the guiding of the discharge guide plate 16, the coal is discharged from the discharge port 3.

[0028] When there is no need to use the conveying shell 1 for coal mine transportation, the operator can start the electric push rod 7, and the push rod of the electric push rod 7 drives the sealing plug plate 8 to slide in the through groove 9 until the sealing surface on one side of the sealing plug plate abuts against the inner wall surface of the feed shell 2, thereby avoiding the situation where dust falls through the feed shell 2 and floats into the interior of the conveying shell 1 when it is not in use, further ensuring the purpose of dust prevention.

[0029] Furthermore, a slide bar 10 is fixedly connected to the central lower surface of the sealing insert plate 8 close to the electric push rod 7 , and a first slide groove 11 for the slide bar 10 to slide is provided on the upper surface of the conveying housing 1 .

[0030] It is worth noting that the sealing insert plate 8 synchronously drives the slide bar 10 to perform a limited sliding motion inside the first slide groove 11 , thereby providing a limiting effect on the sealing sliding insertion of the sealing insert plate 8 .

[0031] Embodiment 2, based on the above embodiment:

[0032] Furthermore, a scraper frame 17 is fixedly installed on the inner bottom wall of the conveying shell 1 near the discharge port 3, and the scraper frame 17 scrapes and fits on the conveying surface of the conveyor belt body 4. A collecting box 18 is slidably installed on one side of the scraper frame 17. The conveying shell 1 is located below the discharge port 3 and is provided with a waste port 21. A rotating shaft plate 24 is fixedly installed on the lower surface of the collecting box 18. A second slide groove 22 is provided on the inner bottom wall of the conveying shell 1 near the discharge port 3. A sliding swivel seat 23 is slidably connected inside the second slide groove 22, and the rotating shaft plate 24 is rotatably connected inside the sliding swivel seat 23. A waste baffle 19 is fixedly connected to the surface of one side of the collecting box 18 near the waste port 21, and the waste baffle 19 slides sealingly inside the waste port 21. A handle 20 is fixedly connected to the surface of the collecting box 18.

[0033] More specifically, in the present embodiment, each time the conveyor belt of the conveyor belt body 4 passes through the scraper frame 17, it will be slid and cleaned by the scraper frame 17, and the cleaned residue will enter the interior of the collection box 18. When the residue in the collection box 18 needs to be cleaned, the handle 20 can be pulled, and the handle 20 drives the waste baffle 19 to slide in the waste port 21. At the same time, the collection box 18 drives the rotating shaft plate 24 and the sliding swivel seat 23 to slide in the same direction in the second slide groove 22. Finally, the design of the rotating shaft plate 24 rotating inside the sliding swivel seat 23 tilts the collection box 18 to facilitate cleaning by the operator.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
