Description

Technical Field

[0001] The present application belongs to the technical field of coal mine engineering machinery, and specifically, relates to cleaning devices and recovery equipment. Background Art

[0002] In the relevant technology, the mining of thin coal seams is mainly based on the longwall mining method, among which the scraper and the transfer machine are important conveying equipment for the transportation of coal in the longwall mining face. In order to meet the needs of mining, in order to improve the efficiency of scraper coal mining and reduce the labor intensity and labor costs of workers, a chute can be set at the head of the scraper in front of the thin coal seam working face. Generally, the chute is used for coal cleaning and then the floating coal is cleaned manually. The floating coal at the bottom of the chute cannot be recovered, resulting in high labor costs and waste. Summary of the invention

[0003] The embodiments according to the present invention are intended to solve or improve at least one of the above technical problems.

[0004] A first object of an embodiment of the present invention is to provide a cleaning device.

[0005] A second object of an embodiment of the present invention is to provide a recycling device.

[0006] In order to achieve the first purpose of an embodiment of the present invention, the technical solution of the present invention provides a cleaning device, including: a power mechanism; a material blocking part, which is connected to the power mechanism; a scraping plate, which is arranged on one side of the material blocking part, and the scraping plate is inclined in a direction away from the material blocking part, and a material trough is formed between the scraping plate and the material blocking part.

[0007] In this technical solution, the power mechanism can drive the material blocking part to move, so as to drive the shoveling plate to perform the cleaning action of shoveling materials. The shoveling plate extends out of the material blocking part and is arranged in a direction away from the material blocking part, which can be used to clean materials and allow the materials to enter the material trough for temporary storage, so as to facilitate the transportation of the cleaned materials. Therefore, the cleaning device can automatically complete the cleaning of materials, avoid manual cleaning, and reduce labor costs and waste.

[0008] In addition, the technical solution provided according to the embodiment of the present invention may also have the following additional technical features:

[0009] In the above technical solution, the material blocking part includes: a box body, and a notch is provided on one side of the box body; wherein the material scraping plate blocks the notch, and the material scraping plate and the side of the box body where the notch is provided form a material trough.

[0010] In this technical solution, the box body is used as a material blocking part, and the notch extends to the bottom of the box body, so that after the shovel plate covers the notch, it can form a material trough with the side of the box body above the notch, so that the box body can not only play a connecting role, but also store a certain amount of material to assist in the automatic cleaning of the material. The structure is simple and reliable.

[0011] In any of the above technical solutions, the box body includes: a top plate; a bottom plate, which is arranged opposite to the top plate, and the width of the bottom plate is greater than or equal to the width of the top plate; a side panel, which is connected between the top plate and the bottom plate; a material panel, which is connected to the top plate, and the material panel and the side panels are spaced apart and opposite to each other, and the width of the material panel gradually increases from one side to the other side opposite to it; wherein, the width of the shoveling plate gradually increases from one side to the other side opposite to it, one side of the shoveling plate is connected to the material panel, and the side of the shoveling plate away from the material panel is connected to the bottom plate, and the first angle formed between the shoveling plate and the bottom plate is an acute angle.

[0012] In this technical solution, the side panel can be connected to the power mechanism as a connecting part. A gap is formed between the material panel and the bottom plate. Since the shoveling plate covers the gap, the width of the bottom plate is greater than the width of the top plate, so that the shoveling plate can be tilted outward, and the first angle formed with the bottom plate is an acute angle, which is conducive to the shoveling plate shoveling materials into the trough. The material panels are of unequal width, so that the shoveling plates connected along the length direction of the material panel can be tilted in the direction away from the box body, and can also be tilted along the material panel, so that the material entering the trough is easier to pour out, saving time and effort, and improving the efficiency of the cleaning device in cleaning materials.

[0014] In this technical solution, the angle between the shoveling plate and the horizontal plane is the first angle, and the first angle is ≤45°, which can ensure that the material is accumulated to a certain height in the trough and prevent the material from exceeding the height of the box body, further increasing the height that the trough can accommodate the material and increasing the dumping speed.

[0015] In any of the above technical solutions, the cleaning device further comprises: a connecting structure, which is arranged between the material blocking part and the power mechanism and enables the material blocking part and the power mechanism to be detachably connected.

[0016] In this technical solution, the connection structure is used to connect the power mechanism and the material blocking part, so that the material blocking part can drive the shoveling plate to complete the corresponding shoveling action. The power mechanism and the material blocking part are detachably connected, which improves the applicability and flexibility of the cleaning device and can improve work efficiency.

[0017] In any of the above technical solutions, the connection structure includes: at least two ear plates, which are respectively connected to the material blocking part and are spaced apart from each other and arranged opposite to each other; and a positioning pin, which is used to pass through the two ear plates and the power mechanism.

The positioning pin runs through the ear plate and a part of the power mechanism, so that the stopper is detachably connected to the power mechanism, and both disassembly and connection are convenient.

[0019] In any of the above technical solutions, the cleaning device further comprises: a hanging ring, which is arranged on the material blocking part.

[0020] In this technical solution, the lifting ring is arranged on the material blocking part, which can facilitate the lifting of the cleaning device and improve the turnover efficiency of the cleaning device.

[0021] In order to achieve the second purpose of the embodiment of the present invention, the technical solution of the present invention provides a recycling equipment, including: a conveying device, the conveying device is provided with a conveying trough; a transfer device, the transfer device is provided with a unloading trough; a cleaning device in any technical solution, the cleaning device is arranged opposite to the unloading trough, and the power mechanism is arranged on the conveying device.

[0022] In this technical solution, the power mechanism is arranged on the conveying device, which has high reliability. The discharge chute and the cleaning device are arranged opposite to each other, so that the cleaning device can automatically clean the floating coal in the chute and automatically dump the floating coal into the discharge chute, and the transfer device can transport the coal to the ground without manual cleaning, which reduces the labor cost, and the overall equipment structure is simple, the failure rate is low, and the maintenance is convenient.

[0023] In addition, the recycling device provided according to the embodiment of the present invention includes the cleaning device according to any embodiment of the present invention, so it has all the beneficial effects of the cleaning device according to any embodiment of the invention.

[0024] In any of the above technical solutions, the height of the shoveling plate is more than 1.5 times the height of the discharge chute, and the height of the material blocking portion is more than 2 times the height of the discharge chute.

[0025] In this technical solution, the height of the material blocking part and the height of the shovel plate are designed relative to the height of the discharge chute, respectively, in order to effectively prevent the accumulated floating coal from crossing the chute and ensure that the cleaning device can smoothly clean the floating coal into the discharge chute.

[0026] In any of the above technical solutions, a second angle is formed between the material blocking portion and the feeding direction of the conveying trough, and the second angle is greater than or equal to 10°, and a third angle is formed between the end of the shovel plate and the feeding direction of the conveying trough, and the third angle is greater than or equal to 25°.

[0027] In this technical solution, the material blocking part is arranged at an angle relative to the feeding direction of the conveying trough, and can guide the trough to pour the floating coal toward the discharge trough. Furthermore, since the shovel plate is arranged at one side of the material blocking part, the shovel plate is also arranged at an angle relative to the feeding direction, which further ensures the guiding direction of the trough to pour the floating coal toward the discharge trough, and finally allows the floating coal to enter the discharge trough for recovery, thereby increasing the coal mining volume, increasing the enterprise benefits, and reducing waste.

The scraper conveyor includes a tail, and the coal cleaning device includes: a base connected to the tail; a shielding cabinet connected to the base for shielding floating coal; and a coal cleaning plate provided at one end of the base away from the tail for cleaning floating coal. The coal cleaning device and the scraper conveyor can automatically intercept and clean the floating coal at the tail of the scraper conveyor through the joint action of the shielding cabinet and the coal cleaning plate, without manual cleaning, thereby reducing the labor intensity and labor cost of workers, and avoiding possible personal injuries caused by manual cleaning of floating coal.

[0041] Refer to the following Figures 1 to 7 A cleaning apparatus 100 and a recycling device 10 are described according to some embodiments of the present invention.

[0042] Example 1

[0043] like Figure 1 As shown, this embodiment provides a cleaning device 100, including: a power mechanism 110, a material blocking portion 120 and a shoveling plate 130, wherein the material blocking portion 120 is connected to the power mechanism 110. The shoveling plate 130 is disposed on one side of the material blocking portion 120, and the shoveling plate 130 is inclined in a direction away from the material blocking portion 120, so that a material trough 140 is formed between the shoveling plate 130 and the material blocking portion 120.

[0044] In this embodiment, the shovel plate 130 is a plate-like structure. The shovel plate 130 is arranged on one side of the material blocking portion 120 and is inclined in a direction away from the material blocking portion 120, so that the shovel plate 130 extends out of the material blocking portion 120 and can be used to clean materials, such as floating coal. The material blocking portion 120 is connected to the power mechanism 110, so that the power mechanism 110 can drive the material blocking portion 120 to move, thereby driving the shovel plate 130 to perform a cleaning action of shoveling materials. The shovel plate 130 and the material blocking portion 120 on one side of the shovel plate 130 form a material trough 140, so that after the shovel plate 130 cleans the material, the material can enter the material trough 140, so as to facilitate the temporary storage of the material in the material trough 140, so as to facilitate the transportation of the cleaned material. Therefore, the cleaning device 100 can automatically complete the cleaning of the material, avoid manual cleaning, and reduce labor costs and waste.

[0045] Example 2

[0046] like Figure 2 As shown, this embodiment provides a cleaning device 100. In addition to the technical features of the above embodiment, this embodiment also includes the following technical features:

[0047] The material blocking portion 120 includes a box body 122 , and a notch 124 is formed on one side of the box body 122 . A material scraping plate 130 blocks the notch 124 , and a material trough 140 is formed between the material scraping plate 130 and the side of the box body 122 where the notch 124 is formed.

[0048] In this embodiment, the interior of the box body 122 is hollow, and the notch 124 is set at a position a certain distance from the top of one side of the box body 122, and the notch 124 extends to the bottom of the box body 122, so that after the shovel plate 130 covers the notch 124, it can form a material trough 140 with the side of the box body 122 above the notch 124, so that the box body 122 can serve as a part of the connecting structure and can also block the material entering the material trough 140, thereby preventing the material entering the material trough 140 from the shovel plate 130 from flowing out again, and the structure is simple and reliable.

[0049] Example 3

[0050] like Figure 2 As shown, this embodiment provides a cleaning device 100. In addition to the technical features of the above embodiment, this embodiment also includes the following technical features:

[0051] The box body 122 includes: a top plate 1222, a bottom plate 1224, a side plate 1226 and a material panel 1228. The bottom plate 1224 is arranged opposite to the top plate 1222, and the width of the bottom plate 1224 is greater than or equal to the width of the top plate 1222. The side plate 1226 is connected between the top plate 1222 and the bottom plate 1224. The material panel 1228 is connected to the top plate 1222, and the material panel 1228 and the side plate 1226 are spaced apart and opposite to each other, and the width of the material panel 1228 gradually increases from one side to the other side opposite to each other. Among them, the width of the shoveling plate 130 gradually increases from one side to the other side opposite to each other, one side of the shoveling plate 130 is connected to the material panel 1228, and the side of the shoveling plate 130 away from the material panel 1228 is connected to the bottom plate 1224, and the first angle α formed between the shoveling plate 130 and the bottom plate 1224 is an acute angle.

[0052] In this embodiment, the widths of the top plate 1222 at the two opposite ends are not equal. For example, the top plate 1222 can be trapezoidal, so that one side of the top plate 1222 is inclined. One end of the side panel 1226 is connected to the top plate 1222, so that the side panel 1226 can be connected to the power mechanism 110 as a connecting part. One end of the material panel 1228 is connected to the top plate 1222, and a gap 124 is formed between the material panel 1228 and the bottom plate 1224. The shoveling plate 130 covers the gap 124, and the width of the bottom plate 1224 is greater than the width of the top plate 1222, so that the shoveling plate 130 is inclined outward, and the first angle α formed between the bottom plate 1224 and the shoveling plate 130 is an acute angle, and the shoveling plate 130 and the material panel 1228 can form a material trough 140. It is beneficial for the shoveling plate 130 to scoop up the material and enter the material trough 140. The material panel 1228 is arranged on the inclined side of the top plate 1222, so that the material panel 1228 can be inclined in the same direction as the inclined side of the top plate 1222, and the width of the material panel 1228 gradually increases or decreases from one side to the opposite side, so that the material can flow along the inclined direction of the material panel 1228, which can facilitate the unloading of the material trough 140. At the same time, since the side of the material panel 1228 located in the notch 124 is an inclined side edge, the bottom position of the material panel 1228 is not at the same height, that is, the width of the material panel 1228 gradually increases from one side to the other opposite side, so that the material panel 1228 is located at a lower position on one of the two opposite sides and a higher position on the other side, so that the shoveling plate 130 covering the notch 124 has a highest position 132 and a lowest position 134, that is, the shoveling plate 130 can be tilted in a direction away from the box body 122, and can also be tilted along the inclined side edge of the material panel 1228, so that the material entering the material trough 140 is easier to pour out, which simplifies the structural design and saves time and effort.

[0053] Combination Figure 2 and Figure 4As shown, the top plate 1222, the material panel 1228 and the shoveling plate 130 are plate structures with different widths respectively, and when the top plate 1222, the material panel 1228 and the shoveling plate 130 are connected, the width and narrowness are set correspondingly, so that the shoveling plate 130 can have a horizontal tilt direction and a vertical tilt direction, thereby improving the efficiency of the cleaning device 100 in cleaning materials.

[0054] In this embodiment, the box body 122 also includes two end side plates 1220, and the two end side plates 1220 are arranged opposite to each other, and are used to adapt to the shapes defined by the bottom plate 1224, the top plate 1222, the material panel 1228, the side panel 1226 and the shoveling plate 130 and make the box body 122 form a closed box structure.

[0055] Example 4

[0056] like Figure 5 As shown, this embodiment provides a cleaning device 100. In addition to the technical features of the above embodiment, this embodiment also includes the following technical features:

[0057] The first angle α is less than or equal to 45°.

[0058] In this embodiment, the bottom plate 1224 is arranged horizontally, and the angle between the shoveling plate 130 and the horizontal plane is the angle between the shoveling plate 130 and the bottom plate 1224. The angle formed between the shoveling plate 130 and the horizontal plane is the first angle α, and the first angle α≤45°, which can be used to ensure that the material is accumulated to a certain height in the trough 140 and prevent the material from exceeding the height of the box body 122. In particular, when the first angle α is 42°, the trough 140 formed by the shoveling plate 130 and the material panel 1228 has an optimal tilt angle, further increasing the height of the material that can be accommodated in the trough 140 and increasing the dumping speed.

[0059] Example 5

[0060] like Figure 1 As shown, this embodiment provides a cleaning device 100. In addition to the technical features of the above embodiment, this embodiment also includes the following technical features:

[0062] In this embodiment, the connection structure 150 is used to connect the material blocking portion 120 and the power mechanism 110, so that the material blocking portion 120 can drive the shoveling plate 130 to complete the corresponding shoveling action. The material blocking portion 120 and the power mechanism 110 are detachably connected, which improves the applicability and flexibility of the cleaning device 100 and can improve work efficiency.

[0065] The connection structure 150 includes: at least two ear plates 152 and a positioning pin 154. The at least two ear plates 152 are respectively connected to the material blocking portion 120 and are spaced apart from each other and arranged opposite to each other.

[0066] In this embodiment, Figure 3 As shown, at least two ear plates 152 can be provided to maintain the stability of the connection structure. The ear plates 152 are connected to the side panels 1226. Both ear plates 152 are provided with through holes. Figure 6 As shown, a frame structure is provided on the power mechanism 110, and at least two ear plate groups are provided on the frame structure. The ear plate group is mainly composed of two vertical plates that are opposite to each other and spaced apart from each other. The ear plate 152 extends into the ear plate group, and a positioning pin 154 penetrates the ear plate 152 and the ear plate group, so that a detachable connection between the material blocking part 120 and the power mechanism 110 can be achieved. The structure is simple and reliable, and disassembly and connection are relatively convenient.

[0078] Example 10

[0079] like Figure 7 As shown, this embodiment provides a recycling device 10. In addition to the technical features of the above embodiment, this embodiment also includes the following technical features:

[0083] Embodiment 11

[0084] like Figure 1 and Figure 7As shown, this embodiment provides a cleaning device 100 and a recovery device 10. The cleaning device 100 is mainly composed of a shovel plate 130, a box body 122, a lifting ring 160 and an ear plate 152. The end of the shovel plate 130 extending out of the box body 122 is a shovel tip. The shovel plate 130 and the box body 122 are welded to form a shovel plate assembly. The shovel plate 130 is used to clean the floating coal at the bottom of the chute 30. Figure 4 As shown, the scraper plate 130 has a highest position 132 and a lowest position 134. The height of the highest position 132 is more than 1.5 times the height of the discharge chute 310, which is convenient for pouring the floating coal in the chute 30 onto the discharge chute 310. The height of the box body 122 is more than 2 times the height of the discharge chute 310, which can prevent the floating coal from passing over the scraper plate 130. The power mechanism 110 is the head push part of the scraper conveyor, which is connected to the box body 122 and can provide power and support for the cleaning device 100. The discharge chute 310 is used for pouring and transporting the floating coal at the bottom of the chute 30. The bracket 220 provides power support for the scraper conveyor push part.

[0085] The head of the scraper conveyor at the front of the thin coal seam working face can be provided with a cleaning device 100. This solves the problem that the floating coal at the bottom of the head of the existing front scraper conveyor needs to be manually cleaned and cannot be recovered. The cleaning device 100 is mainly composed of an integrally welded scraper plate assembly, a head pusher and a connecting piece of the scraper conveyor, and a bracket, and is used in conjunction with the unloading chute 310 of the transfer machine.

[0086] like Figure 7 As shown, when the cleaning device 100 is used underground, the box 122 meets the size requirements. The positioning pin 154 is connected to the head push part, the distance between the box 122 and the discharge chute 310 is greater than or equal to 100mm, and the distance between the box 122 and the coal wall 32 of the chute 30 is ≥100mm. The box 122 forms an inclination angle of ≥25° with the layout direction of the middle trough of the scraper conveyor, and moves with the random head push part. The positioning pin 154 is then lifted and the lifting ring 160 is then lifted to complete the disassembly. The conveying trough 210 is a middle trough. The scraper conveyor is a scraper conveyor.

[0087] In this embodiment, the angle between the box 122 and the middle slot of the scraper is ≥10°, and the height of the box 122 is ≥2.5 times the unloading chute of the transfer machine, which can guide the floating coal in the chute to pour toward the transfer machine. The angle between the shovel tip of the shovel assembly and the horizontal plane is ≤45°, which can ensure the efficiency of cleaning the floating coal in the chute. The angle between the shovel tip and the middle slot of the scraper is ≥25°, and the height of the highest point of the shovel tip is ≥1.5 times the unloading chute of the transfer machine. The above inclination angles are used to ensure that the floating coal at the bottom of the chute 30 accumulates to a certain height, and prevent the floating coal from crossing the box 122 in the chute 30, guiding the accumulated floating coal to move in the direction of the transfer machine, and then pouring onto the chute of the transfer machine.

[0088] The cleaning device 100 uses vertical and horizontal inclination angles to guide the flow direction of coal. The floating coal is cleaned and recovered at the same time, which increases the coal mining volume, increases the enterprise benefits, and reduces waste. The coal cleaning and recovery device at the bottom of the chute has a simple structure, high reliability, low failure rate, low cost, easy maintenance, and no additional power requirements for the power mechanism (support).

[0089] When the cleaning device 100 is used underground, the head shovel plate assembly is arranged in the front scraper head flume, connected to the front scraper pusher ear plate through the connecting positioning pin 154, and moves toward the coal wall as the bracket to remove floating coal at the bottom of the flume.

[0090] The cleaning device 100 is not only used for scraper conveyors at underground coal mine working faces, but can also be widely promoted and used at transfer interface locations in other transportation fields.

[0091] In summary, the beneficial effects of the embodiments of the invention are as follows:

[0092] 1. The cleaning device 100 automatically cleans the materials through the shovel plate 130 and pours out the accumulated materials through the material trough 140, eliminating the need for manual cleaning and reducing labor costs.

[0093] 2. By connecting the cleaning device 100 between the conveying device 200 and the transfer device 300 underground, the cleaning and recovery of floating coal can be automatically completed, thereby increasing the coal mining volume, reducing energy waste, and increasing profits.
