Description

Technical Field

[0001] This utility model relates to the field of material collection technology, specifically to a belt conveyor sampling device. Background Technology

[0002] In the production of materials such as coal and ore, belt sampling is an important step. It is a process of automatically collecting bulk material samples from a running belt conveyor. The material needs to be sampled and collected without stopping the belt conveyor.

[0003] The existing sampling process usually involves sampling personnel standing on one side of a belt conveyor with a sampling shovel. Since the belt conveyor is running continuously, the material travels at a relatively high speed and has a large impact force. During sampling, there is a high risk that the sampling shovel or the personnel may be caught in the running belt. Therefore, this method of operation has a high safety hazard and is also inefficient. Furthermore, this method of collection cannot achieve full-section sample collection, which affects the accuracy of the samples. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a belt conveyor sampling device.

[0005] This utility model is achieved through the following technical solution:

[0006] A belt conveyor sampling device includes a frame and a conveyor belt fixed to the upper part of the frame. A support frame is provided on the upper part of the conveyor belt. A sampling shovel that can rotate in a circle is provided on the support frame. An inclined and retractable receiving chute is provided on one side of the sampling shovel. A receiving box is provided at the outlet of the receiving chute. A retractable receiving container is provided inside the receiving box.

[0007] Alternatively, one side of the sampling shovel is open, and a rotating shaft is fixedly connected to the lower part of the opening. The rotating shaft is rotatably supported inside the support frame, and one end extends to the outside of the support frame and is equipped with a crank handle at the end. The crank handle is located outside the conveyor belt.

[0008] Alternatively, the receiving chute may consist of a movable chute and a fixed chute.

[0009] Alternatively, the movable chute is fitted inside the fixed chute, with sliding grooves on both sides of the movable chute. A sliding rod matching the sliding groove is provided inside the fixed chute, and push rods are connected and fixed to the outside of the fixed chute. The telescopic rods of the corresponding push rods are connected and fixed to the movable chute.

[0010] Alternatively, guide rods are provided on both sides of the receiving box, and a limiting groove is provided on the inside of the receiving box to cooperate with the guide rods. The guide rods are slidably connected to the limiting groove.

[0011] Alternatively, the receiving box may be equipped with a handle on the outside for easy pulling.

[0012] Alternatively, the support frame may be provided with a pull-out limiting rod, one end of which extends to the outside of the support frame and has a pull ring at the end.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting a sampling shovel that can rotate in a circular motion on the upper part of the conveyor belt, this utility model fundamentally solves a series of problems caused by hand-held sampling shovels, greatly avoids safety hazards to operators during sampling, improves sampling efficiency, and ensures sampling accuracy.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1 , 2 As shown in Figure 3, a belt conveyor sampling device includes a frame 1 and a conveyor belt 2 fixed on the upper part of the frame 1. A support frame 7 is provided on the upper part of the conveyor belt 2. A sampling shovel 3 that can rotate in a circular motion is provided on the support frame 7. An inclined and retractable receiving chute 4 is provided on one side of the sampling shovel 3. A receiving box 5 is provided at the outlet of the receiving chute 4. A retractable receiving container 6 is provided inside the receiving box 5.

[0020] like Figure 1 , 2 As shown, the sampling shovel 3 has an opening on one side, and a rotating shaft 8 is fixedly connected to the lower part of the opening. The rotating shaft 8 is rotatably supported inside the support frame 7 and one end extends to the outside of the support frame 7, with a crank handle 9 at the end. The crank handle 9 is located outside the conveyor belt 2.

[0021] like Figure 1 , 2As shown in Figure 3, the receiving chute 4 consists of a movable chute 10 and a fixed chute 11.

[0022] like Figure 1 , 2 As shown in Figure 3, the movable chute 10 is fitted inside the fixed chute 11. Slide grooves 12 are respectively opened on both sides of the movable chute 10. A slide rod 13 matching the slide groove 12 is provided on the inner side of the fixed chute 11. Push rods 14 are connected and fixed on both sides of the outside of the fixed chute 11. The telescopic rods of the corresponding push rods 14 are connected and fixed to the movable chute 10.

[0023] like Figure 2 As shown, guide rods 15 are provided on both sides of the receiving box 6, and a limiting groove 16 that cooperates with the guide rods 15 is provided on the inner side of the receiving box 5. The guide rods 15 and the limiting groove 16 are slidably connected.

[0024] like Figure 2 As shown, the outer side of the receiving box 6 is provided with a handle 17 for easy pulling.

[0025] like Figure 1 , 2 As shown, a pull-out limiting rod 18 is provided on the support frame 7. One end of the limiting rod 18 extends to the outside of the support frame 7 and a pull ring 19 is provided at the end.

[0026] The implementation principle of a belt conveyor sampling device according to an embodiment of this application is as follows:

[0027] During sampling, first pull the ring 19 to pull out the limiting rod 18. After pulling out the limiting rod 18, turn the handle 9. While turning the handle 9, the sampling shovel 3 connected to the rotating shaft 8 will move in a circular motion. The direction of rotation of the sampling shovel 3 is opposite to the direction of material transport by the conveyor belt 2. When rotating in the opposite direction, the relative movement between the sampling shovel 3 and the material is relatively gentle, reducing the instantaneous impact force. At the same time, when rotating in the opposite direction, the sampling shovel 3 can contact the material at different depths and positions of the conveyor belt, rather than being limited to the surface or a specific area, thus more accurately reflecting the overall composition and characteristics of the material.

[0028] When the sampling shovel 3 rotates vertically downwards, the push rod 14 is activated. The push rod 14 pushes out the movable chute 10 to receive the material collected by the sampling shovel 3. When the sampling shovel 3 rotates to its highest point, the sample collected will be discharged from the tail of the sampling shovel 3 into the movable chute 10. The sample discharged into the movable chute 10 will slide down and slide through the fixed chute 11 into the receiving box 6 in the receiving box 5. After sliding into the receiving box 6, the handle 17 is pulled to pull it out of the receiving box 5 and pour the collected sample into the designated container. At the same time, the push rod 14 is activated to retract, so that the movable chute 10 retracts into the fixed chute 11 to prevent it from affecting the next sampling rotation of the sampling shovel 3. The limit rod 18 is inserted into the support frame 7 and the sampling shovel 3 is placed on top of it to prevent the sampling shovel 3 from rotating and causing damage to the equipment.
