Description

Technical Field

[0001] The utility model relates to the technical field of pulverized coal processing, in particular to a sampling buffer platform. Background Art

[0002] Pulverized coal refers to a specialized process that transforms raw coal into a powdered form suitable for various industrial applications. Pulverized coal's physical properties, such as particle size, moisture content, fluidity, and combustion performance, are crucial to its effectiveness. Therefore, pulverized coal processing technology prioritizes the control of these parameters. Consequently, sampling and inspection are essential during pulverized coal processing, particularly at the point of unloading.

[0003] Sampling and observing pulverized coal mainly involves observing and testing the state of the pulverized coal or the quality of the pulverized coal, because the quality of the pulverized coal directly affects the efficiency and effect of the use of pulverized coal. When machinery and equipment are producing pulverized coal, workers generally use a sampling shovel to take samples from the discharge port of the pulverized coal. During the sampling process, the sampling shovel is first inserted from the hole on the side wall of the discharge port to the position where the pulverized coal falls. The sampling shovel will cut off part of the pulverized coal that continues to fall, and the pulverized coal that is blocked from falling will fall onto the sampling shovel. However, when the pulverized coal falls onto the sampling shovel, because the sampling shovel is in a suspended state, it will produce a certain impact force on the sampling shovel, which will cause damage to the sampling tool. It will also cause impact force on the worker holding the sampling shovel, and the worker's arm will be injured if caught off guard.

[0004] Based on the above situation, it is necessary to design a sampling buffer platform to solve the above problems. Utility Model Content

[0005] The utility model provides a sampling buffer platform to solve the problems of the sampling buffer platform in the prior art.

[0006] The technical problem solved by the present invention is achieved by the following technical solutions:

[0007] A sampling buffer platform includes a feeding channel and a sampling port that can be opened and closed and is provided on the side wall of the feeding channel. It also includes: a buffer plate for placing a sampling shovel, the buffer plate is located inside the feeding channel near the sampling port, and the upper end surface of the buffer plate is close to the horizontal plane of the lower edge of the sampling port; a telescopic rod, the telescopic rod is located inside the feeding channel and is composed of a plurality of hollow tubes, and the movable end of the telescopic rod is connected to the buffer plate; a support assembly, the telescopic rod and the buffer plate are supported and stabilized by the support assembly when they are stationary and in use.

[0008] Furthermore, the support assembly includes a slot plate fixedly connected to the movable end of the telescopic rod, the slot plate is fixedly connected to the lower end surface of the buffer plate, and the telescopic rod is connected to and supports the buffer plate through the slot plate.

[0009] Furthermore, the support assembly further comprises a fixing plate connected to the telescopic rod and a support block fixedly connected to the fixing plate, wherein one end of the support block away from the fixing plate contacts the slot plate.

[0010] Furthermore, the support assembly also includes a support frame fixedly connected to the inner wall of the discharge channel, and one end of the support frame is connected to the telescopic rod.

[0011] Furthermore, the buffer plate is provided with a plurality of long through grooves for preventing the accumulation of pulverized coal, and the buffer plate is provided with an arc groove.

[0012] Furthermore, a stop rod is fixedly connected to one end of the buffer plate away from the sampling port.

[0013] Furthermore, a spring is fixedly connected inside the telescopic rod, and two ends of the spring are fixedly connected to the movable end and the fixed end of the telescopic rod respectively.

[0014] The beneficial effect of the present invention is that a buffer plate for placing a sampling shovel is provided in the pulverized coal feeding channel, so that when a worker uses the sampling shovel to take samples, the sampling shovel can be supported, avoiding the worker from continuously holding the sampling shovel for sampling, and reducing the impact force on the sampling shovel transmitted to the worker. The buffer plate is provided on the telescopic rod, so that the buffer plate can move synchronously with the sampling shovel, which is more convenient for the worker to use the sampling shovel for sampling. Compared with the worker directly using the sampling shovel to reach into the falling place of the pulverized coal for sampling, this method of providing the buffer plate saves more energy, and the sampling shovel is not in a suspended state. Therefore, when the falling pulverized coal impacts the sampling shovel, the buffer plate can reduce the impact force on the sampling shovel, thereby reducing damage to the sampling tool, and thus reducing the damage to the worker's arm caused by the impact force, making it safer for the worker to sample the pulverized coal.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0023] Reference Figure 1-Figure 5 As shown, a sampling buffer platform includes a feeding channel 1. When pulverized coal is produced and fed, the pulverized coal will fall through the output end of a conveyor belt (not shown in the figure), and the output end of the conveyor belt extends to the inside of the feeding channel 1, so the falling process of the pulverized coal is carried out inside the feeding channel 1. In order to facilitate the sampling of the falling pulverized coal, an openable and closable sampling port 2 is opened in the feeding channel 1. Workers can sample the pulverized coal through the sampling port 2. The sampling method is generally to insert a sampling shovel from the position of the sampling port 2, and then the falling pulverized coal will fall onto the sampling shovel, and then the sampling shovel filled with pulverized coal is taken out to complete the sampling operation of the pulverized coal.

[0024] In the existing pulverized coal sampling method, since the sampling shovel is in a suspended state, the pulverized coal will cause a certain impact on the sampling shovel during the falling process, and the impact force will be transmitted along the sampling shovel to the human body, which will cause a certain burden on the human arm, and may cause damage to the worker's arm if caught off guard. Therefore, in order to facilitate the carrying of the sampling shovel and reduce the burden on the worker's arm, a buffer plate 3 for placing the sampling shovel is provided inside the feeding channel 1. The buffer plate 3 is located inside the feeding channel 1 near the sampling port 2, and the upper end surface of the buffer plate 3 is close to the horizontal plane of the lower edge of the sampling port 2. Therefore, when the sampling shovel is placed on the buffer plate 3 from the sampling port 2, it can be placed smoothly and stably on the buffer plate 3.

[0025] like Figure 3 As shown, when the sampling shovel is placed on the buffer plate 3 and the sampling shovel is sampling the pulverized coal, the pulverized coal will inevitably fall onto the buffer plate 3. In order to prevent the pulverized coal from accumulating too much on the buffer plate 3, a plurality of long through grooves 9 are provided on the buffer plate 3 to prevent the pulverized coal from accumulating. The pulverized coal accumulated on the buffer plate 3 will fall along the long through grooves 9, and the plurality of long through grooves 9 will not affect the stability of the sampling shovel when it is placed. In order to adapt to the stability of the sampling shovel when it is placed, some sampling shovels have a bottom. The bottom of the sampling shovel is in an arc shape, so when it is placed on a flat buffer plate 3, especially after a certain weight is placed on the sampling shovel, the sampling shovel with an arc shape on the bottom will inevitably tilt to one side. At this time, the worker needs to exert a certain force to correct the sampling shovel. However, this also puts a certain burden on the worker's arm. Therefore, an arc groove 10 is provided on the buffer plate 3. When the sampling shovel with an arc shape on the bottom is placed on the buffer plate 3, the bottom of the sampling shovel will be stuck on the arc groove 10, thereby stabilizing the sampling shovel.

[0026] like Figure 3 As shown, after the sampling shovel is placed on the buffer plate 3, the sampling shovel needs to be moved to the position where the pulverized coal begins to fall. During the movement, the sampling shovel will generate friction between the buffer plate 3, and friction means that the worker needs to apply a certain force to the sampling shovel to prompt the sampling shovel to move back and forth, especially after the sampling shovel carries the pulverized coal. At this time, the weight of the sampling shovel increases, and the worker needs to apply more force to retract the sampling shovel. At this time, a number of telescopic rods 4 are arranged under the buffer plate 3 to assist the movement of the buffer plate 3. The telescopic rod 4 is located inside the discharge channel 1 and is composed of a number of hollow tubes 5. The movable end of the telescopic rod 4 is connected to the buffer plate 3, and the fixed end of the telescopic tube is fixedly connected to the inner wall of the discharge channel 1. The movable end of the telescopic rod 4 drives the buffer plate 3 to move, and during the movement, the telescopic rod 4 can also support the buffer plate 3.

[0027] The buffer plate 3 can be moved under the action of the telescopic rod 4, and the force required for movement comes from the force applied by the worker to the sampling shovel. In order to better transmit the force on the sampling shovel to the buffer plate 3, a gear rod 12 is fixedly connected to the end of the buffer plate 3 away from the sampling port 2. When the sampling shovel is placed on the buffer plate 3, the front end of the sampling shovel will conflict with the gear rod 12. When the worker pushes the sampling shovel forward, the sampling shovel will resist the gear rod 12, thereby pushing the buffer plate 3 to move synchronously. Among them, some sampling shovels have a sharp front end, and a single gear rod 12 is not conducive to the interference of such sampling shovels. Therefore, two or more gear rods 12 are set on the buffer plate 3 to meet a better interference relationship between the sampling shovel and the buffer plate 3.

[0028] like Figure 3As shown, a friction pad 11 is provided on the buffer plate 3, and the friction pad 11 is made of a non-slip and durable material. The friction pad 11 avoids the long through groove 9 on the upper end surface of the buffer plate 3 and is in close contact with the upper end surface of the buffer plate 3 and the arc groove 10. When the sampling shovel is placed on the friction pad 11 on the buffer plate 3, and when the sampling shovel is retracted carrying the pulverized coal, it is only necessary to pull the sampling shovel, and the friction between the sampling shovel and the friction pad 11 enables the sampling shovel to drive the buffer plate 3 to move and retract synchronously.

[0029] like Figure 5 As shown, a spring 13 is fixedly connected inside the telescopic rod 4, and both ends of the spring 13 are fixedly connected to the movable end and the fixed end of the telescopic rod 4 respectively. When the sampling shovel drives the buffer plate 3 to be retracted, the movable end of the telescopic rod 4 will be retracted synchronously. Because there is a certain friction between the several hollow tubes 5 of the telescopic rod 4, the spring 13 inside the telescopic rod 4 is conducive to the retraction of the movable end of the telescopic rod 4. If the worker directly removes the sampling shovel from the buffer plate 3, the telescopic rod 4 can also drive the buffer plate 3 to return to its initial position under the action of the spring 13.

[0030] When the buffer plate 3 and the telescopic rod 4 carry the sampling shovel, the buffer plate 3 and the telescopic rod 4 will be affected by the sampling shovel. If there is no supporting structure to support the buffer plate 3 and the telescopic rod 4, the buffer plate 3 and the telescopic rod 4 will inevitably deform over time, which will affect the use effect of the buffer plate 3. Therefore, a support component is set on the buffer plate 3 and the telescopic rod 4, and the telescopic rod 4 and the buffer plate 3 are supported and stabilized by the support component when they are stationary and in use.

[0031] Specifically, such as Figure 3-5 As shown, the support assembly includes a slot plate 6 fixedly connected to the movable end of the telescopic rod 4, the slot plate 6 is fixedly connected to the lower end surface of the buffer plate 3, the telescopic rod 4 is connected to and supports the buffer plate 3 through the slot plate 6, and the movable end of the telescopic rod 4 drives the buffer plate 3 to move through the slot plate 6. In addition, the movable end of the telescopic rod 4 can support and stabilize the buffer plate 3, and the force applied by the sampling shovel to the buffer plate 3 will be transmitted to the telescopic rod 4 through the slot plate 6.

[0032] The support assembly also includes a fixed plate 7 connected to the telescopic rod 4 and a support block 70 fixedly connected to the fixed plate 7. According to actual use needs, several support blocks 70 can be set. The end of the support block 70 away from the fixed plate 7 is in contact with the slot plate 6. The support block 70 is set to better support the buffer plate 3. When the buffer plate 3 is stationary and not in use, the weight of the buffer plate 3 itself is supported by the movable end of the telescopic rod 4. Under the action of the support block 70, the weight of the buffer plate 3 itself is also transferred to the fixed end of the telescopic rod 4 through the support block 70. The fixed end of the telescopic rod 4 is directly fixedly connected to the inner wall of the discharge channel 1. When the buffer plate 3 moves, the contact relationship between the support block 70 and the slot plate 6 ensures that the support block 70 will not affect the movement of the buffer plate 3, and can support the buffer plate 3 when the buffer plate 3 moves, thereby reducing the pressure of the slot plate 6 on the movable end of the telescopic rod 4.

[0033] The support assembly also includes a support frame 8 fixedly connected to the inner wall of the discharge channel 1, one end of the support frame 8 is connected to the telescopic rod 4, and after the telescopic rod 4 bears the weight of the buffer plate 3, in order to ensure the stability of the telescopic rod 4 itself during use, the support frame 8 can transfer the force from the telescopic rod 4 to the side wall of the discharge channel 1 to reduce the burden of the telescopic rod 4 when supporting the buffer plate 3.
