[0030] Coal is widely used in industrial production such as steel, electricity, chemical industry and residents' life. It is one of the indispensable sources of energy for human production and life. After the production and processing of coal is completed, it is often necessary to use chain conveyors to transport the coal to silos for storage.

[0031] Since coal often falls when being transported to nearby silos (it falls directly to the ground without entering the silo) and is scattered outside the silo, the current practice is to manually clean the top of the silo regularly, which causes a waste of manpower and has local limitations.

[0032] In order to solve the problems in the related technology to a certain extent, an embodiment of the present application provides a pneumatic device suitable for leakage at the head of a conveyor belt, the device is provided with a cleaning component 3, after the coal is transported to the unloading bin 2, the cleaning component 3 is started, the pneumatic device 32 is extended and retracted to drive gear 1 34 to rotate on the rack 33, and then gear 1 34 drives gear 2 35 to rotate in the opposite direction, so that the cleaning brush 36 can clean the top area of ​​the unloading bin 2 when moving toward the feed hopper 21, which can not only quickly clean and save manpower, but also recover scattered coal and save resources.

[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Combination Figure 1-Figure 4 The embodiment of the present application provides a pneumatic device suitable for leakage of a conveyor belt head, comprising a chain conveyor 1; a discharge bin 2 is arranged at one end of the chain conveyor 1; the discharge bin 2 is also provided with: a feed hopper 21 is connected to the top of the discharge bin 2; an entry slot 22 is opened on both sides of the feed hopper 21; a cleaning assembly 3 is also arranged on the discharge bin 2, and the cleaning assembly 3 comprises: a fixed seat 31 is arranged on the outer periphery of the discharge bin 2; a pneumatic device 32 is arranged on the fixed seat 31; a rack 33 is arranged on the fixed seat 31; a gear 1 34 is rotatably connected to the telescopic end of the pneumatic device 32, and the gear 1 34 is meshed with the rack 33; a gear 2 35 is rotatably connected to the telescopic end of the pneumatic device 32; and the gear 1 34 is meshed with the gear 2 35; a slide rail 1 37 is arranged on the fixed seat 31; one end of a cleaning brush 36 is fixedly connected to the gear 2 35, and the other end of the cleaning brush 36 is movably connected to the slide rail 1 37.

[0035] After the coal is produced, it is generally transported via a chain conveyor 1 and finally transported to a discharge bin 2 for storage. Unlike the traditional solution, the device is provided with a cleaning component 3. When the chain conveyor 1 drives the coal to be transported, the cleaning component 3 is started. The cleaning component 3 is mainly powered by a pneumatic device 32. The telescopic end of the pneumatic device 32 is provided with a meshing gear 1 34 and a gear 2 35, wherein the gear 1 34 is also meshed with a rack 33 on a fixed seat 31. The operation of the pneumatic device 32 drives the gear 1 34 to move. Under the action of the rack 33 It rotates and drives gear 2 35 to rotate in the opposite direction. A cleaning brush 36 is provided on gear 2 35, and the cleaning brush 36 is close to the upper wall of the unloading bin 2. When the pneumatic device 32 drives the cleaning brush 36 to move in the direction of the feed hopper 21, the cleaning brush 36 rotates in the opposite direction under the action of gear 1 34 and gear 2 35, so as to clean the coal dropped on the unloading bin 2. Finally, under the push of the cleaning brush 36, the scattered coal is re-entered into the unloading bin 2 through the entry slot 22, which not only completes the cleaning, but also saves resources and eliminates waste, killing two birds with one stone.

[0036] In some embodiments, the outlet end of the chain conveyor 1 is arranged directly above the feed hopper 21 , so that the coal can enter the discharge bin 2 during normal unloading.

[0037] In some embodiments, multiple groups of cleaning components 3 are provided to greatly increase the cleaning efficiency.

[0038] In some embodiments, the cleaning components 3 are arranged in a circular array. Generally, two groups of cleaning components 3 are arranged, one group is arranged on both sides of the feed hopper 21, and the two groups are symmetrical about the center, so that the entire upper wall of the discharge bin 2 can be cleaned.

[0039] In some embodiments, the cleaning assembly 3 further includes: a ceiling 38 disposed above the unloading bin 2, and the ceiling 38 can shield the position of the hopper 21 on rainy days to prevent rainwater from seeping in.

[0040] In some embodiments, the feed hopper 21 is configured to be square. Since the outlet end of the chain conveyor 1 is square, it can not only better receive the coal to reduce scattering, but also reduce sanitary dead corners when the cleaning component 3 is cleaned.

[0041] In some embodiments, the cleaning assembly 3 further includes: a second slide rail 39 disposed on the fixing seat 31, and a second gear 35 disposed on the second slide rail 39. The second slide rail 39 can stably fix the other end of the cleaning brush 36 to increase the stability of the entire device.

[0042] In some embodiments, the cleaning brush 36 is a brush, which can clean scattered coal with maximum efficiency. In the description of this specification, the description of reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0043] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0044] 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.
