Description

Technical Field

[0001] This utility model relates to the field of limestone processing technology, and in particular to a limestone conveyor belt feed port sampling device. Background Art

[0002] Limestone is a calcium carbonate rock with calcite (mineral) as its main component, and it is primarily formed in shallow marine environments. It can be directly processed into stone or burned into quicklime.

[0003] When limestone conveyor belts are in operation, the material volume is large and the speed is fast. It is inconvenient to manually collect the material by opening the guard at the feed port of the belt and using tools. In addition, during the operation, because the material is discharged very fast, personnel are prone to dropping tools when sampling, which may affect the equipment below or hit the sampling personnel and cause personal injury. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a limestone conveyor belt discharge port sampling device, which solves the technical problems of inconvenient material collection by manually using tools through openings in the conveyor belt discharge port cover, and the risk of personnel dropping tools during sampling due to the high speed of material discharge, which could damage the equipment below or cause personal injury to the sampling personnel.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A limestone conveyor belt discharge port sampling device includes a fixed frame, a receiving pipe fixedly installed at the side end of the fixed frame, a connecting pipe fixedly installed at the top end of the receiving pipe, a sampling pipe fixedly installed at the top end of the connecting pipe, a collar fixedly installed at the end of the sampling pipe, a fixed seat fixedly installed on the inner side of the fixed frame, and telescopic rods rotatably installed at both sides of the fixed seat.

[0009] Preferably: a steel wire rope is slidably installed on the side end of the fixing frame, two positioning sleeves are fixedly installed on the surface of the steel wire rope, a base plate is fixedly installed on the outer side of the fixing frame, two side plates are fixedly installed on the top of the base plate, two spring rods are fixedly installed on the inner side of each side plate, the same arc-shaped clamping block is fixedly installed on the top of each of the two spring rods, a limit block is slidably installed on the bottom end of each arc-shaped clamping block, a spring rod is fixedly installed on the top of each limit block, and at least two grooves are formed on the top of the base plate.

[0010] (III) Beneficial Effects

[0011] 1. By pushing the sampling tube inward, the sampling tube can sample the limestone material. During sampling, it is fixed and overlapped with the receiving tube. The limestone material flows out to the outside through the connecting tube and the receiving tube. The head of the sampling tube is a sieve-shaped receiving box made of iron plate. The collar on the outer surface of the sampling tube, together with the steel wire rope, is used to control the opening and closing of the sampling tube, which facilitates material collection and increases the safety of use.

[0012] 2. The spring rod pushes the arc-shaped clamping blocks to slide against each other and fit with the positioning sleeve, restricting the movement of the wire rope and preventing the sampling tube from falling. At the same time, the movement of the arc-shaped clamping blocks causes the limiting block to slide at the top of the base plate. Under the reverse force of the reset rod, the force applied by the reset rod to the limiting block causes the limiting block to insert downward into the top of the base plate, positioning the arc-shaped clamping blocks and increasing stability.

[0019] This application embodiment provides a limestone conveyor belt discharge port sampling device, which effectively solves the problems of inconvenient manual material collection using tools through openings in the conveyor belt discharge port cover, and the risk of dropping tools that could damage lower equipment or cause personal injury to the sampling personnel due to the rapid material flow during operation. By pushing the sampling tube inward, the sampling tube can sample the limestone material. During sampling, it is fixed and overlapped with the receiving tube. The limestone material flows out to the outside through the connecting pipe and the receiving pipe. The head of the sampling tube is a scoop-shaped receiving box made of iron plate. The collar on the outer surface of the sampling tube, together with a steel wire rope, is used to control the opening and closing of the sampling tube, facilitating material collection and increasing safety during use. Example

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problems of inconvenient material handling by manually using tools to receive materials through openings in the conveyor belt discharge port cover, and the risk of personnel dropping tools during sampling due to the high speed of material discharge, which could damage lower equipment or cause personal injury to the sampling personnel. The overall approach is as follows:

[0021] To address the problems existing in the prior art, this utility model provides a limestone conveyor belt unloading port sampling device, including a fixed frame 1. A receiving pipe 11 is fixedly installed on the side end of the fixed frame 1, and a connecting pipe 12 is fixedly installed on the top end of the receiving pipe 11. A sampling pipe 13 is fixedly installed on the top end of the connecting pipe 12. A collar 14 on the outer surface of the sampling pipe 13, in conjunction with a steel wire rope 18, is used to control the opening and closing of the sampling pipe 13. At the same time, by pulling the steel wire rope 18, the positioning sleeve 17 is driven to slide on the side end of the fixed frame 1. A collar 14 is fixedly installed at the end of the sampling pipe 13. A fixed seat 16 is fixedly installed on the inner side of the fixed frame 1. Telescopic rods 15 are rotatably installed on both sides of the fixed seat 16. The top end of the telescopic rod 15 is rotatably connected to the side end of the collar 14. The telescopic rod 15 itself is a telescopic structure. A belt transmission device is installed inside the fixed frame 1. The connecting pipe 12 itself is a flexible connecting material that can be bent.

[0022] A steel wire rope 18 is slidably installed on the side end of the fixed frame 1. Two positioning sleeves 17 are fixedly installed on the surface of the steel wire rope 18. A base plate 19 is fixedly installed on the outer side of the fixed frame 1. Two side plates 24 are fixedly installed on the top of the base plate 19. Two spring rods 22 are fixedly installed on the inner side of each side plate 24. The same arc-shaped clamping block 21 is fixedly installed on the top of each of the two spring rods 22. Moving the two arc-shaped clamping blocks 21 causes the arc-shaped clamping blocks 21 to drive the limiting block 23 to move. Under the reverse force of the spring rods 22, the limiting block 23 slides downward and inserts into the groove at the top of the base plate 19. By releasing the fixing of the positioning sleeves 17, the bottom end of each arc-shaped clamping block 21 is slidably installed with a limiting block 23. The top of each limiting block 23 is fixedly installed with a spring rod 22. At least two grooves are opened at the top of the base plate 19.

[0023] Working principle:

[0024] In the first step, during use, a conveyor belt is installed inside the fixed frame 1 to transport the limestone raw materials. By pushing the two arc-shaped clamps 21, the two arc-shaped clamps 21 are separated from each other, allowing the arc-shaped clamps 21 to move away from the side end of the positioning sleeve 17. The arc-shaped clamps 21 press the top of the spring rod 22, forcing the spring rod 22 to extend and retract. At the same time, the arc-shaped clamps 21 drive the limiting block 23 to slide on the top of the base plate 19. The limiting block 23 first presses the reset rod 25, forcing the reset rod 25 to compress at the bottom end of the arc-shaped clamps 21. Simultaneously, the two arc-shaped clamps 21 are moved, allowing the arc-shaped clamps 21 to drive the limiting block 23 to move. Under the reverse force of the reset rod 25, the limiting block 23 slides downward and inserts into the groove at the top of the base plate 19. By releasing the fixation of the positioning sleeve 17, the tension applied to the wire rope 18 is released. Under the force of the sampling tube 13, the sampling tube 13 flips inward toward the fixed frame 1. At the same time, the sampling tube 13 drives the collar 14 to move, so that the collar 14 stretches the end of the telescopic rod 15. While the telescopic rod 15 rotates at the side end of the fixed seat 16, the telescopic rod 15 itself is a telescopic structure. The telescopic rod 15 also extends and retracts downward, so that the sampling tube 13 deflects inward. At the same time, the sampling tube 13 drives the connecting tube 12 to bend.

[0025] The second step involves simultaneously pushing the sampling tube 13 inwards to sample the limestone material. The connecting tube 12 is 520mm long and 10mm in diameter. During sampling, it is fixed and overlapped with the receiving tube 11. The limestone material flows out through the connecting tube 12 and the receiving tube 11 to the outside. The head of the sampling tube 13 is a scoop-shaped receiving box made of iron plate, with an outer length of 400mm and a diameter of 10mm. The collar 14 on the outer surface of the sampling tube 13, together with the steel wire rope 18, is used to control the opening and closing of the sampling tube 13. Simultaneously, by pulling... The wire rope 18 drives the positioning sleeve 17 to slide at the side end of the fixed frame 1. The spring rod 22 pushes the arc-shaped clamping block 21 to slide against each other and fit with the positioning sleeve 17, restricting the movement of the wire rope 18 and preventing the sampling tube 13 from falling. At the same time, the movement of the arc-shaped clamping block 21 drives the limiting block 23 to slide at the top of the base plate 19. Under the reverse force of the reset rod 25, the reset rod 25 applies a force to the limiting block 23, causing the limiting block 23 to insert downward into the top of the base plate 19, positioning the arc-shaped clamping block 21 and increasing stability.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
