[0001] The present disclosure relates to the technical field of coal mine comprehensive mining, and in particular to a coal accumulation cleaning device and a chute assembly. Background Art

[0002] In the related art, during the screening and processing of raw coal in a coal preparation plant, since the raw coal mined from the mine contains a certain amount of moisture, the water-containing coal is prone to accumulation in the chute. If it is not cleaned in time, the chute is easily blocked. The existing method for cleaning the accumulated coal in the chute is usually to manually clean the accumulated coal with a shovel, or to move a coal scraper back and forth in the chute to clean the accumulated coal. However, manual cleaning of the accumulated coal is time-consuming and labor-intensive. When the coal scraper is used to scrape and clean the coal in the chute, the raw coal is easily agglomerated due to its high moisture content, and is easily attached to the coal scraper to increase the load of the coal scraper.

[0022] The specific embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not used to limit the present disclosure. In the present disclosure, unless otherwise stated, the directional words used, such as "inside and outside", refer to the inside and outside relative to the outline of the component or structure itself; "first, second" and the like are used to distinguish one element from another, and do not have order and importance. In addition, the same figure mark in different reference figures represents the same element.

[0023] In a first aspect of the present disclosure, a coal accumulation cleaning device is provided, referring to Figures 1 to 3 As shown, the coal accumulation cleaning device includes a driving mechanism 1 and a cleaning mechanism 2, wherein the cleaning mechanism 2 is connected to the driving end of the driving mechanism 1; and the driving mechanism 1 is used to drive the cleaning mechanism 2 to move along the extension direction of the chute 4 to scrape off the accumulated coal attached to the inner wall of the chute 4, and a gap 201 is formed on the cleaning mechanism 2 for allowing part of the accumulated coal to pass through.

[0024] Through the above scheme, that is, the coal accumulation cleaning device provided by the present invention, when the coal accumulation in the chute 4 is cleaned by the coal accumulation cleaning device, the driving mechanism 1 can drive the cleaning mechanism 2 to move back and forth along the extension direction of the chute 4, so that the coal accumulation attached to the inner wall of the chute 4 can be cleaned, and when the coal accumulation attached to the inner wall of the chute 4 has a lot of moisture and is agglomerated, the gap 201 formed on the cleaning mechanism 2 can allow the coal accumulation with a lot of moisture to pass through the cleaning mechanism 2, so as to reduce the weight of the coal accumulation attached to the cleaning mechanism 2 itself, thereby reducing the problem of the overall load of the coal accumulation cleaning device caused by the coal accumulation attached to the cleaning mechanism 2, so that the coal accumulation on the inner wall of the chute 4 can be better cleaned by the coal accumulation cleaning device.

[0025] In some embodiments, reference Figures 1 to 3As shown, the cleaning mechanism 2 includes a cleaning component 210 and a splitting component 220. The cleaning component 210 is at least partially attached to the chute 4 to scrape the coal accumulation adhering to the inner wall of the chute 4. The splitting component 220 is connected to the cleaning component 210 and forms a gap 201 therebetween. The splitting component 220 is used to break part of the coal accumulation passing through the gap 201. In this way, the cleaning component 210 can clean the coal accumulation on the inner wall of the chute 4 by attaching to the inner wall of the chute 4. At the same time, the splitting component 220 can split the coal accumulation that forms lumps due to more moisture in the chute 4, and the split coal accumulation can pass through the gap 201 to achieve the effect of breaking the coal accumulation, that is, reference can be made to Figure 2 and Figure 3 As shown, when the driving mechanism 1 drives the cleaning mechanism 2 to reciprocate along the length direction of the chute 4, the cleaning component 210 can repeatedly scrape the coal accumulation on the inner wall of the chute 4. At the same time, when the coal accumulation forms large lumps due to more moisture, the splitting component 220 will also split the coal accumulation with large lumps along the extending direction of the chute 4. Then, the large coal accumulation can be split into smaller pieces of coal, and the cleaning component 210 moving reciprocally can clean the broken coal out of the chute 4. Therefore, the cleaning component 210 and the splitting component 220 cooperate with each other to first split the coal accumulation and then clean it, thereby reducing the situation of more coal accumulation in the chute 4.

[0026] In some embodiments, reference is made to Figures 1 to 3 As shown, the number of the gaps 201 is multiple. In this way, multiple gaps 201 can jointly allow the broken coal accumulation to pass through. And in the arrangement where the number of the gaps 201 is multiple, the splitting component 220 can also break the coal accumulation with more moisture more thoroughly, that is, the coal accumulation can be broken into smaller pieces of coal, and it is also convenient for the subsequent cleaning component 210 to clean the coal accumulation, that is, reference can be made to Figure 1 and Figure 3 As shown, the splitting component 220 divides the cleaning mechanism 2 into four gaps 201, and the four gaps 201 are arranged in a "field" shape. In this arrangement, after the splitting component 220 breaks the coal accumulation, the broken coal accumulation can pass through the four gaps 201 respectively, and then the cleaning component 210 can scrape and clean the coal accumulation, thereby completing the process of breaking and cleaning the coal accumulation.

[0027] It should be noted that the number of the gaps 201 being four described in the above specific embodiments is exemplary, and the present disclosure is not limited thereto. For example, the number of the gaps 201 can also be two, three or more, and the present disclosure does not make specific limitations thereto.

[0028] In some embodiments, reference is made to Figures 1 to 3As shown, the cleaning assembly 210 includes a connecting member 211 and a cleaning member 212, wherein the connecting member 211 is connected to the driving end of the driving mechanism 1; the cleaning member 212 is connected to the connecting member 211 and is used to fit the chute 4. In this way, when the cleaning assembly 210 scrapes and cleans the accumulated coal in the chute 4, it can be connected to the driving end of the driving mechanism 1 through the connecting member 211, and the cleaning member 212 can be driven by the connecting member 211 to fit the inner wall surface of the chute 4, and reciprocate along the inner wall surface of the chute 4, so that the accumulated coal on the inner wall surface of the chute 4 can be repeatedly scraped.

[0029] In some embodiments, reference Figures 1 to 3 As shown, the cleaning member 212 includes a first cleaning portion 2121 and a second cleaning portion 2122. The number of the first cleaning portions 2121 is two and they are respectively connected to the two ends of the connecting member 211, so as to respectively fit the two opposite side walls of the chute 4; the second cleaning portion 2122 is connected between the two first cleaning portions 2121, and the second cleaning portion 2122 is used to fit the inner bottom surface of the chute 4. In this way, when the cleaning member 212 reciprocates along the length direction of the chute 4, the coal accumulation on the side wall surface of the chute 4 can be cleaned by the two first cleaning portions 2121, and the inner bottom surface of the chute 4 can be cleaned by the second cleaning portion 2122. In this cleaning method, the first cleaning portion 2121 and the second cleaning portion 2122 work together to clean the coal accumulation in the chute 4 in a more all-round manner, thereby improving the cleaning efficiency of the chute 4.

[0030] In some embodiments, reference Figures 1 to 3 As shown, the two first cleaning portions 2121 extend obliquely from the connecting member 211 toward the second cleaning portion 2122. In this way, when the side wall of the chute 4 has a certain inclination angle, the two obliquely extending first cleaning portions 2121 can better clean the coal accumulation on the side wall of the chute 4, that is, it can be understood that the inclination angle of the side wall of the chute 4 relative to the vertical direction can be the same as the inclination angle of the two first cleaning portions 2121 relative to the vertical direction, that is, the extension direction of the first cleaning portion 2121 is parallel to the side wall of the chute 4, so that the first cleaning portion 2121 can be completely attached to the side wall of the chute 4 when it is attached to the side wall of the chute 4, and thus the coal accumulation on the side wall of the chute 4 can be better cleaned.

[0031] It should be noted that the first cleaning portion 2121 is not limited to the tilting manner in the above specific embodiment. Figure 1 and Figure 3As shown, the two first cleaning portions 2121, the second cleaning portion 2122 and the connecting member 211 together form an inverted trapezoidal structure, so that the accumulated coal on the inner wall surface of the inverted trapezoidal chute 4 can be cleaned. When the inner wall surface of the chute 4 is configured as other shapes, the inclination angle of the first cleaning portion 2121 can also be adaptively adjusted. For example, when the inner wall surface of the chute 4 is configured as a rectangle, the first cleaning portion 2121 can extend in the vertical direction. When the inner wall surface of the chute 4 is configured as a right trapezoid, the two first cleaning portions 2121, the second cleaning portion 2122 and the connecting member 211 can together form a right trapezoidal shape that is the same as the shape of the inner wall surface of the chute 4 to adapt to the shape of the chute 4. The present disclosure does not limit this.

[0032] In some embodiments, reference Figures 1 to 3 As shown, two first cleaning parts 2121, a second cleaning part 2122 and a connecting member 211 form a polygonal frame, and the dividing assembly 220 includes at least one partition 221, and at least one partition 221 is connected to the polygonal frame to divide the inner space of the polygonal frame into a plurality of gaps 201, and the partition 221 is used to break up some of the coal deposits passing through the gaps 201. In this way, the partition 221 can divide the large pieces of coal deposits in the chute 4, that is, it can be understood that when the polygonal frame reciprocates along the length direction of the chute 4, the partition 221 will continuously divide the large pieces of coal deposits during the reciprocating movement of the polygonal frame, and then the large pieces of coal deposits can be divided into smaller pieces of coal, which is convenient for the first cleaning part 2121 and the second cleaning part 2122 to clean and scrape the coal deposits.

[0033] It should be noted that in the above-mentioned specific embodiment, the specific shape of the partition 221 can also be any suitable one. For example, in order to improve the efficiency of dividing large pieces of coal, the partition 221 can be set to a conical structure on the front and rear sides along the length direction of the chute 4. The conical structure can better divide the large pieces of coal, thereby improving the effect of dividing the coal. Alternatively, the partition 221 can also be provided with any other suitable structure that can divide the coal. The present disclosure does not make specific limitations on this.

[0034] In some embodiments, reference Figures 1 to 3 As shown, the driving mechanism 1 is constructed as a hydraulic cylinder or a synchronous belt transmission mechanism. In this way, the hydraulic cylinder or the synchronous belt transmission mechanism can be connected to the cleaning mechanism 2, and can drive the cleaning mechanism 2 to move back and forth along the length direction of the chute 4 to clean the coal accumulation in the chute 4. Among them, when the driving mechanism 1 is constructed as a hydraulic cylinder, it can be applied to the application scenario where the length of the chute is relatively short, and when the driving mechanism is constructed as a synchronous belt transmission mechanism, it can be applied to the application scenario where the length of the chute is relatively long, and the present disclosure does not make specific limitations on this.

[0035] In addition, after the coal accumulation cleaning device has finished cleaning the accumulated coal in the chute 4, in order to enable the chute 4 to transport coal normally, the connection relationship between the cleaning mechanism 2 and the driving mechanism 1 can be designed to be detachable. For example, the connecting member 211 can be detachably connected to the driving end of the driving mechanism 1. When it is necessary to clean the accumulated coal in the chute 4, the connecting member 211 can be connected to the driving end of the driving mechanism 1 so that the accumulated coal in the chute 4 can be cleaned normally through the coal accumulation cleaning device. After the accumulated coal in the chute 4 is cleaned, the connecting member 211 can be removed from the driving end of the driving mechanism 1, so that the chute 4 can continue to transport coal normally.

[0036] It should be noted that the coal cleaning device can be installed in conjunction with the chute 4 in any suitable manner when cleaning the accumulated coal in the chute 4, and the present disclosure does not make any specific limitation on this. For example, the upper end of a general chute 4 has an opening, and a mounting frame for installing the coal cleaning device can be added to the opening at the upper end of the chute 4, and the coal cleaning device can be installed above the mounting frame to complete the installation in conjunction with the chute 4.

[0037] In some embodiments, reference Figures 1 to 3 As shown, the coal accumulation cleaning device also includes a control switch 3, which is connected to the driving mechanism 1 by signal. In this way, the control switch 3 can control the start and stop of the driving mechanism 1, and can further control the travel of the cleaning mechanism 2 along the length direction of the chute 4. In this arrangement, the staff can more conveniently control the cleaning time and cleaning range of the coal accumulation cleaning device for the coal accumulation.

[0038] It should be noted that the control switch 3 can be any suitable form of control switch. For example, the control switch 3 can be a control button connected to the drive mechanism 1 by wire, or it can be a remote control that wirelessly controls the drive mechanism. The present disclosure does not make specific limitations on this.

[0039] According to a second aspect of the present disclosure, there is provided a chute assembly, comprising a chute 4 and the coal accumulation cleaning device mentioned in the above specific embodiments, and the chute assembly has all the beneficial effects of the above specific embodiments.

[0040] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0042] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
