Description

Technical Field

[0001] This utility model relates to the technical field of floating coal sampling devices, and in particular to a floating coal sampling device. Background Technology

[0002] In existing technologies, when sampling small coal lumps and coal powder, sampling is usually carried out after a single transport and stockpiling. This sampling method can only sample the surface of the coal pile, and the sampling is incomplete. Therefore, it is necessary to design a floating coal sampling device. Utility Model Content

[0003] Therefore, it is necessary to provide a floating coal sampling device to address the aforementioned technical problem of incomplete sampling.

[0004] To achieve the above objectives, this utility model provides a floating coal sampling device, including a frame, on which a belt conveyor and idlers are mounted. A transmission mechanism is mounted on the frame, and the output end of the transmission mechanism is connected to the idlers via a transmission component. An auger conveyor is mounted on the frame, and the output end of the transmission mechanism is connected to the auger conveyor via a transmission assembly. A discharge baffle is mounted on the frame, and the discharge baffle is clearance-fitted with the upper surface of the belt conveyor. The auger conveyor is provided with a feed inlet located on the extension line of the discharge baffle.

[0005] Preferably, the transmission mechanism includes a first bevel gear and a second bevel gear, which are meshed together. The first bevel gear is connected to the idler roller, and the second bevel gear is connected to the auger conveyor via a transmission assembly.

[0007] Preferably, the idler roller is provided with a square slot, and a square block is installed on the bevel gear, the square block being slidably engaged in the square slot.

[0008] Preferably, a ratchet disc is rotatably mounted on the frame, and an inner rotating disc is mounted on the auger conveyor. The inner rotating disc is located inside the ratchet disc, and several pawls are hinged on the inner rotating disc. The pawls are configured to cooperate with the ratchet disc. A spring is mounted on the inner rotating disc, and the spring provides a thrust for the pawls to deflect outward. Several push rods are mounted on the inner rotating disc.

[0009] Preferably, a protective door is hinged to the frame, the protective door is located on one side of the push rod, and a laser signal sensor is installed on the frame, the laser signal sensor being configured in conjunction with the protective door.

[0010] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: 1. The auger conveyor is driven by idler rollers to operate, so that during the conveying and feeding process of the belt conveyor, the auger conveyor can continuously collect splashed materials, thereby achieving the purpose of uniform sampling throughout the process. 2.

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Please see Figures 1 to 4This application provides a floating coal sampling device, including a frame 1, on which a belt conveyor 2 and idler rollers 3 are mounted. The belt conveyor 2 is a belt conveyor with a built-in servo motor, as is the case in the prior art. The idler rollers 3 are in contact with the belt and are driven to rotate by it. A transmission mechanism 4 is fixedly mounted on the frame 1, and the output end of the transmission mechanism 4 is connected to the idler rollers 3. An auger conveyor 5 is fixedly mounted on the frame 1, and the output end of the transmission mechanism 4 is connected to the auger conveyor 5 through a transmission component 6. The transmission component 6 can be a belt drive component, as is the case in the prior art, including a belt, pulleys, and other structures. A discharge baffle 7 is fixedly mounted on the frame 1, and the discharge baffle 7 is clearance-fitted with the upper surface of the belt conveyor 2. The auger conveyor 5 is provided with a feed inlet 8, which is located on the extension line of the discharge baffle 7.

[0014] In this embodiment, when the belt conveyor 2 conveys materials, it can drive the idler roller 3 to rotate. The rotating idler roller 3 can then drive the auger conveyor 5 to rotate via the transmission mechanism 4. When the material conveyed by the belt conveyor 2 is blocked by the discharge baffle 7, the material is guided out by the discharge baffle 7 due to the collision with it. During the collision, the material splashes, allowing it to fall into the feed inlet 8 of the auger conveyor 5 and be continuously discharged by the operating auger conveyor 5. The belt conveyor 2 is relatively large because it transports a large amount of material. The belt conveyor provides a large amount of power to the idler roller 3. The auger conveyor 5 only needs to sample a small amount of material, so it is a miniaturized design. The feed inlet 8 only needs to be located on the extension line of the discharge baffle 7 to collect splashed material. The auger conveyor 5 can also be designed to be cool, such as only the blades and impeller at the discharge inlet 8 being made of metal, while other internal impellers can be made of lightweight materials such as high-strength polypropylene. The discharge inlet of the auger conveyor 5 is located at the bottom of the side away from the discharge baffle 7, so it can share a guide plate with the belt conveyor 2 without mixing.

[0015] In some embodiments, to facilitate the operation of the transmission mechanism 4, the transmission mechanism 4 includes a first bevel gear 9 and a second bevel gear 10, which are meshed together. The first bevel gear 9 is driven by the idler roller 3, and the second bevel gear 10 is driven by the auger conveyor 5 through the transmission assembly 6. Through the meshing of the first bevel gear 9 and the second bevel gear 10, the power of the idler roller 3 can be transmitted to the auger conveyor 5; and the operating speed of the auger conveyor 5 can be adjusted to a suitable level by using different tooth ratios of the first bevel gear 9 and the second bevel gear 10.

[0016] In some embodiments, to protect bevel gear 9 and bevel gear 10 and prevent material from entering and affecting meshing, bevel gear 9 and bevel gear 10 are rotatably mounted in protective housing 11, and protective housing 11 is mounted on frame 1 by bolt fasteners.

[0017] In some embodiments, to facilitate the transmission between the idler roller 3 and the bevel gear 9, a square slot 12 is provided on the idler roller 3, and a square block 13 is fixedly installed on the bevel gear 9. The square block 13 is slidably engaged in the square slot 12. After the square block 13 is inserted into the square slot 12, the protective box 11 is then installed on the frame 1 using bolts and fasteners.

[0018] In some embodiments, to facilitate the operation of the auger conveyor 5, a ratchet disk 14 is rotatably mounted on the frame 1, and an inner rotating disk 15 is fixedly mounted on the inner blade shaft of the auger conveyor 5. The inner rotating disk 15 is located inside the ratchet disk 14, and a plurality of pawls 16 are hinged on the inner rotating disk 15. The pawls 16 are configured to cooperate with the ratchet disk 14. A crank spring 17 is fixedly mounted on the inner rotating disk 15, and the crank spring 17 provides a thrust for the pawls 16 to deflect outward. A plurality of push rods 18 are fixedly mounted on the inner rotating disk 15. When the idler roller 3 drives the auger conveyor 5 to operate, the power source is transmitted to the inner rotating disk 15 via the ratchet disc 14. The inner rotating disk 15 can drive the impeller shaft inside the auger conveyor 5 to rotate together. During transmission, the crank spring 17 provides an outward pushing force to the pawl 16, so that the pawl 16 can abut and lock with the inner groove on the ratchet disc 14, allowing the ratchet disc 14 and the inner rotating disk 15 to rotate together. When the belt conveyor 2 finishes conveying materials and stops working, the workers can clean the auger conveyor 5 at the same time as cleaning the discharge baffle 7 and the guide plate on one side of the belt conveyor 2. During cleaning, the workers can rotate several push rods 18 to make the inner rotating disk 15 rotate. At this time, the pawl 16 will only continuously collide with the ratchet disc 14 without getting stuck and driving it to rotate together, thus achieving a labor-saving effect. The inner rotating disk 15 and the ratchet disc 14 are fitted with a clearance, and a protective shell can be installed on the outside to prevent materials from entering.

[0019] In some embodiments, to ensure worker safety, a protective door 19 is hinged to the frame 1, located on one side of the push rod 18. A laser signal sensor 20 is fixedly installed inside the frame 1, and the laser signal sensor 20 is configured to cooperate with the protective door 19. The laser signal sensor 20 can be connected to an external signal processor. The laser signal sensor 20 can detect whether the protective door 19 is closed and send a signal, thereby preventing workers from being injured by the push rod 18 while observing the working conditions through the protective door 19.

[0020] The fixed connection and rotating installation in the above embodiments can all be achieved by welding, screw fasteners and other forms in the prior art, and the rotating installation can be achieved by bearings, circular rotating blocks and circular grooves. All of the above components are standard parts, and those that are not standard parts can also be specially customized, so the inventor will not elaborate further.

[0021] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0022] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
