[0022] 1. Guide member; 101. Guide rod; 102. Fixed seat; 2. Coal pusher; 210. Groove portion; 3. Driving member; 301. Mounting seat; 4. Hydraulic integrated valve group; 410. Liquid inlet and return pipelines. DETAILED DESCRIPTION
[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0024] In the present disclosure, unless otherwise specified, the terms "first" and "second" used in the present disclosure are for the purpose of distinguishing one element from another and have no order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0025] according to Figure 1 As shown, the example of the present disclosure provides a coal cleaning device for cleaning the floating coal remaining on the body of the coal mining machine when the coal mining machine is working. Specifically, the coal cleaning device includes a coal pushing plate 2, a driving member 3 and a guide member 1. The coal pushing plate 2 is arranged on the body of the coal mining machine along a first direction X. One end of the driving member 3 is connected to the coal pushing plate 2, and the other end is connected to the coal mining machine. The driving member 3 is used to drive the coal pushing plate 2 to move along a second direction Y perpendicular to the first direction X. Through the cooperation of the driving member 3 and the coal pushing plate 2, the floating coal remaining on the body of the coal mining machine is cleaned. The guide member 1 extends along the second direction Y. The coal pushing plate 2 is movably connected to the guide member 1. When the driving member 3 drives the coal pushing plate 2 to move along the second direction Y, it plays a guiding role to avoid the coal pushing plate 2 from moving and deforming under the driving action of the driving member 3.
[0026] Through the above technical solution, the driving member 3 drives the coal pushing plate 2 to move along the second direction Y to clean the floating coal remaining on the coal mining machine body, and the guide member 1 connected to the coal pushing plate 2 is used to ensure the stability of the coal pushing plate 2 during the working process, so as to reduce safety hazards and improve the safety and stability of the operation process.
[0027] It should be noted that the coal pushing plate 2 can be a plate with a certain height and extending along the first direction X. The certain height is to prevent the accumulated floating coal from passing over the coal pushing plate 2 and falling on the other side of the coal pushing plate 2 due to insufficient height when pushing the floating coal on the body of the coal mining machine.
[0028] The structure of the driving member 3 can be adaptively adjusted according to actual conditions. For example, the driving member 3 can be constructed as a driving cylinder, an electric push rod, and other adaptive structures. The present disclosure does not make specific limitations on this, as long as it can realize its function of pushing the coal pushing plate 2 to move along the second direction Y.
[0029] In order to facilitate the movement of the coal pushing plate 2 relative to the guide member 1 along the second direction Y, in other feasible embodiments, the connection relationship between the coal pushing plate 2 and the guide member 1 can be adaptively adjusted according to actual conditions, for example, the coal pushing plate 2 and the guide member 1 can be slidably connected or rolled. The present disclosure does not make specific limitations on this, as long as its function can be achieved.
[0030] In some embodiments, for example, reference Figure 1 As shown, in order to facilitate the stability of the coal pushing process of the coal pushing plate 2, the guide member 1 may include a guide rod 101, which is slidably connected to the coal pushing plate 2, and both ends of the guide rod 101 are fixedly connected to the body of the coal mining machine through a fixed seat 102, so that the coal pushing plate 2 is arranged between the two fixed seats 102 and slides in the second direction Y along the guide rod 101, so as to clean the floating coal.
[0031] It should be noted that the two fixed seats 102 are respectively arranged on the opposite sides of the coal pushing plate 2 in the second direction Y, and one of the fixed seats 102 can be close to the coal dropping side of the coal mining machine body, so that the coal pushing plate 2 can push as much floating coal as possible to the coal dropping side of the body and drop it.
[0032] In order to facilitate the disassembly and installation of the guide member 1, the fixing seats 102 at both ends of the guide rod 101 can be connected to the body of the coal mining machine by bolt connection.
[0033] In order to prevent floating coal from adhering to the guide rod 101 and affecting the movement of the coal pushing plate 2, in some embodiments, a protective member such as a protective cover can be provided above the guide rod 101 to avoid affecting the normal operation of the coal cleaning device. In addition, those skilled in the art can also adopt any other appropriate method to protect the guide rod 101.
[0034] The structure of the guide member 1 can be adaptively adjusted according to actual conditions. For example, in other feasible embodiments, the guide member 1 can also be constructed as a guide box with a slide groove, and the coal pushing plate 2 is partially arranged in the guide box and can slide along the slide groove in the second direction Y, which can also realize the function of the above-mentioned guide member 1. The present disclosure does not make specific limitations on this.
[0035] In some embodiments, the number of guide members 1 may be multiple, and the multiple guide members 1 are arranged at intervals along the first direction X, so as to better guide the coal pushing plate 2. For example, the guide members 1 may be two or three, or may be four or more guide rods 101, and the multiple guide rods 101 are arranged at intervals along the first direction.
[0036] In some embodiments, for example, reference Figure 1 As shown, the number of the guide members 1 can be two, and the two guide members 1 are arranged in parallel and spaced apart along the first direction X.
[0037] The driving member 3 needs to be arranged on the machine body, and it will occupy a certain space in the second direction Y, thereby affecting the position of the coal pushing plate 2 in the second direction Y. In some embodiments, for example, referring to Figure 1 As shown, in order to ensure that the telescopic distance of the driving member 3 can match the width of the coal mining machine body along the second direction Y and increase the coal pushing area, the coal pushing plate 2 is formed with a groove portion 210 that is recessed in the direction away from the driving member 3 along the second direction Y. One end of the driving member 3 can be connected to the body away from the coal falling side, and the other end is connected to the bottom of the groove portion 210. It should be noted that the coal falling side of the body can be as follows Figure 1 The connection position of the upper two fixing seats 102 shown in the figure, or the position slightly above the connection position, can be referred to as the dotted line in the figure.
[0038] It should be noted that the structural limitation of the coal pushing plate 2 in the present disclosure is only for the present disclosure, and the structure of the coal pushing plate 2 can be adaptively adjusted according to actual conditions. The present disclosure does not make any special limitation on this, as long as its function can be achieved.
[0039] In some embodiments, there can be only one driving member 3 of the disclosed embodiment, and one end of the driving member 3 is connected to the machine body, and the other end is connected to the middle of at least two guide members 1 of the coal pushing plate 2. By pushing the driving member 3 and guiding the two guide members 1, the coal pushing plate 2 can be moved stably in the second direction Y, and the coal pushing plate 2 will not be deflected due to the uneven resistance of the floating coal, making it impossible to clean the floating coal.
[0040] In some embodiments, the number of the groove parts 210 and the driving member 3 can be multiple, and the number of the groove parts 210 and the driving member 3 corresponds to each other, that is, one end of each driving member 3 connected to the coal pushing plate 2 is connected to the groove bottom of the groove part 210, which can meet the premise of the installation of the driving member 3 and try to arrange at least part of the coal pushing plate 2 away from the coal falling side. For example, the number of the groove parts 210 and the driving member 3 can be two to provide sufficient thrust. Of course, the number of the groove parts 210 and the driving member 3 can also be set to three or four, and the present disclosure does not make specific limitations on this.
[0041] In some embodiments, for example, reference Figure 1 As shown, in order to improve the coal pushing efficiency and stability of the coal pushing plate, the number of the groove portions 210 and the driving members 3 can be two, and the two groove portions 210 and the two driving members 3 are arranged along the first direction X at intervals.
[0042] In some embodiments, for example, reference Figure 1 As shown, in order to facilitate the disassembly and replacement of the driving member 3, the side of the driving member 3 facing away from the coal pushing plate 2 can be detachably connected to the coal mining machine through the mounting seat 301. The other side of the driving member 3 can also be detachably connected to the groove portion 210 of the coal pushing plate 2.
[0043] In some embodiments, for example, reference Figure 1 As shown, the driving member 3 can be configured as a driving cylinder.
[0044] It should be noted that the structural limitation of the driving member 3 in the present disclosure is only for the present disclosure, and the structure of the driving member 3 can be adaptively adjusted according to actual conditions, for example, a cylinder, an electric push rod, or other linear modules are all possible. The present disclosure does not make any special limitation on this, as long as it can achieve its function.
[0045] An embodiment of the present disclosure further provides a coal mining machine, which includes the above-mentioned coal cleaning device, and the coal cleaning device can be installed on the top of the body of the coal mining machine to clean the floating coal on the top.
[0046] In order to facilitate the direct control of the coal cleaning device by the controller to clean the floating coal on the coal mining machine body, in some embodiments, the coal mining machine further includes a hydraulic integrated valve group 4, which is connected to the driving cylinder through the inlet and return liquid pipeline 410, and the hydraulic integrated valve group 4 is used to drive the driving cylinder to move along the second direction Y. The coal mining machine has all the beneficial effects of the above-mentioned coal cleaning device, which will not be described in detail in this disclosure.
[0047] It should be noted that the liquid inlet and return pipeline 410 may include an oil inlet pipeline and an oil return pipeline, and are respectively connected to the oil inlet and oil return ports of the hydraulic integrated valve group 4. At the same time, the hydraulic integrated valve group 4 can be controlled by the control system of the coal mining machine to realize the oil inlet or oil return of the oil inlet pipeline and the oil return pipeline, thereby realizing the extension and retraction of the driving cylinder, thereby pushing the coal pushing plate 2 to extend or retract. The specific connecting pipelines can refer to the relevant hydraulic field technology, which will not be repeated here.
[0048] The present disclosure describes the coal cleaning process of the coal cleaning device by way of example, for example: one end of the driving member 3 is connected to the coal mining machine body through the mounting seat 301, and the other end is connected to the coal pushing plate 2 arranged on the coal mining machine body, and then the fixing seats 102 at both ends of the guide member 1 are installed on the coal mining machine body, so that the coal pushing plate 2 is located between the two fixing seats 102 of the guide member 1, so that when the driving member 3 drives the coal pushing plate 2 to move along the second direction Y toward the coal falling side, the guide member 1 plays a guiding role, improves the stability when cleaning the floating coal, and avoids the coal pushing plate from moving and deforming during the movement; when the floating coal cleaning is completed, the driving member 3 moves in the reverse direction, driving the coal pushing plate 2 to retract. Furthermore, the hydraulic integrated valve group 4 of the coal mining machine can be connected to the driving member 3 through the inlet and return liquid pipeline 410, so as to control the hydraulic integrated valve group 4 through the control system of the coal mining machine to drive the driving cylinder to move along the second direction Y, which is convenient for actual automatic control, so as to save labor costs and improve work efficiency.
[0049] 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.
[0050] 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.
[0051] 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.
