Description

Technical Field

[0001] This utility model relates to the field of bulk material sampling technology in industries such as cement and building materials, specifically to a belt conveyor head sampling machine. Background Technology

[0002] In the production processes of industries such as cement and building materials, automated sampling of bulk materials (such as cement mixtures) at the discharge point of conveyor belts is a crucial step in quality control. Traditional sampling methods have significant drawbacks: manual sampling is inefficient, carries high safety risks, and is difficult to operate at high-speed discharge points; it is also difficult to obtain the real-time, accurate state of the material at the discharge end, resulting in insufficient sample representativeness. This severely affects sampling accuracy and equipment reliability. Therefore, there is an urgent need to design a conveyor belt head sampling machine to address the problems of poor sample representativeness and operational safety risks in existing technologies. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides a belt conveyor head sampling machine.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a belt conveyor head sampling machine, including a sampling mechanism, a transmission mechanism, and a guide rail. The transmission mechanism and the guide rail are fixed to the top of the support base. The sampling mechanism is slidably connected to the inner wall of the guide rail. The output end of the transmission mechanism is connected to the sampling mechanism. The transmission mechanism drives the sampling mechanism to slide on the inner wall of the guide rail. A material outlet is provided on one side of the guide rail. Material is discharged from top to bottom inside the material outlet. The sampling mechanism samples the material inside the material outlet.

[0005] In one specific embodiment, the transmission mechanism consists of a motor, a lead screw, and a transmission seat. The motor is fixedly connected to the support base, and the output end of the motor is fixedly connected to the lead screw. One end of the lead screw is rotatably connected to the support base, and the outer wall of the lead screw is threaded with a transmission seat.

[0006] In one specific embodiment, the sampling mechanism consists of a sampling plate, a connecting rod, a transmission plate, rollers, and baffles. Rollers are rotatably connected to both sides of the sampling plate, and the rollers are rotatably connected to the inner wall of the guide rail. Baffles are fixedly connected to the top of both sides of the sampling plate. A connecting rod is fixedly connected to one end of the sampling plate, and a transmission plate is fixedly connected to one end of the connecting rod. The transmission plate and the transmission seat are fixedly connected by bolts.

[0007] In one specific embodiment, the material discharged from the inner side of the material outlet is a cement mixture, the support base is a brick wall that supports and fixes the transmission mechanism and the guide rail, and the guide rail is a C-shaped steel plate.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. The motor-driven lead screw drives the transmission seat to achieve precise linear reciprocating motion. Combined with the C-shaped steel plate guide rail and roller guide support structure, this ensures low-resistance and smooth sliding of the sampling mechanism, allowing the sampling plate to traverse the material flow falling from the material outlet at high speed and with precision. The side baffles effectively block lateral splashing and longitudinal overflow of material due to inertia, ensuring that the intercepted material is retained sufficiently and completely within the sampling range. This significantly improves the representativeness and reliability of the sampling (especially for easily dusty materials such as cement mixtures), achieving automated, high-efficiency, safe, and reliable material interception, providing core assurance for quality control in industries such as cement and building materials.

[0014] like Figures 1 to 2 The belt conveyor head sampling machine shown includes a sampling mechanism 1, a transmission mechanism 2, and a guide rail 3. The transmission mechanism 2 and the guide rail 3 are fixed to the top of the support base 4. The sampling mechanism 1 is slidably connected to the inner wall of the guide rail 3. The output end of the transmission mechanism 2 is connected to the sampling mechanism 1. The transmission mechanism 2 drives the sampling mechanism 1 to slide on the inner wall of the guide rail 3. A material outlet 5 is provided on one side of the guide rail 3. Material is discharged from top to bottom inside the material outlet 5. The sampling mechanism 1 samples the material inside the material outlet 5.

[0015] The transmission mechanism 2 consists of a motor 21, a lead screw 22 and a transmission seat 23. The motor 21 is fixedly connected to the support base 4. The output end of the motor 21 is fixedly connected to the lead screw 22. One end of the lead screw 22 is rotatably connected to the support base 4. The outer wall of the lead screw 22 is threaded with the transmission seat 23.

[0016] The sampling mechanism 1 consists of a sampling plate 11, a connecting rod 12, a transmission plate 13, rollers 14 and baffles 15. Rollers 14 are rotatably connected to both sides of the sampling plate 11. The rollers 14 are rotatably connected to the inner wall of the guide rail 3. Baffles 15 are fixedly connected to the top of both sides of the sampling plate 11. A connecting rod 12 is fixedly connected to one end of the sampling plate 11. A transmission plate 13 is fixedly connected to one end of the connecting rod 12. The transmission plate 13 and the transmission seat 23 are fixedly connected by bolts.

[0018] In summary, this utility model has the following working principle:

[0019] Power and Transmission (Transmission Mechanism 2):

[0020] Motor 21: Provides power source and precisely controls start, stop, forward and reverse rotation and speed.

[0021] Lead screw 22: Converts the rotational motion of motor 21 into precise and controllable linear motion.

[0022] Transmission seat 23: As the nut part of lead screw 22, it engages with lead screw 22 by thread and directly bears the linear driving force brought by the rotation of lead screw 22. It is the core actuator for linear output of the mechanism.

[0023] Guidance and support:

[0024] C-shaped steel plate guide rail 3: Provides a robust and stable straight track for the sliding of sampling mechanism 1, ensuring the accurate movement trajectory of sampling plate 11. The C-shaped structure effectively accommodates the rollers and prevents derailment.

[0025] Rollers 14 are installed on both sides of the sampling plate 11 and roll within the C-shaped steel plate guide rail 3, which greatly reduces the sliding friction resistance, making the reciprocating motion of the sampling mechanism 1 smooth, labor-saving and with little wear.

[0026] Brick wall support base 4: Provides strong and stable foundation support, bearing and fixing the entire transmission mechanism, guide rail and working load, ensuring stable operation of the equipment under vibration and heavy load.

[0027] Sampling execution (sampling agency 1):

[0028] Transmission plate 13 and connecting rod 12: Transmission plate 13 is rigidly connected to transmission seat 23 (fixed by bolts) and is the interface through which power is transmitted from transmission mechanism 2 to sampling plate 11. Connecting rod 12 connects transmission plate 13 and sampling plate 11, transmitting linear driving force.

[0029] Sampling plate 11: The core sampling component, whose width is usually designed to be slightly larger than the width of the material flow. Driven by motor 21, it crosses the falling material flow at high speed and with precision to physically intercept material samples. Its crossing speed and position control directly affect the representativeness and integrity of the sampling.

[0030] Baffle 15: Located at the top of both sides of the sampling plate 11, its key function is to prevent lateral splashing (dust) and longitudinal overflow of material under inertia when the sampling plate 11 passes through the high-speed falling material flow. This forces most of the intercepted material to remain on the sampling plate 11 (or in the collection area behind the plate), thus ensuring that a complete and sufficient sample representing the entire cross-section of the material is captured. This is crucial for sampling easily dusty and highly fluid materials such as cement mixtures.

[0031] Sampling point location:

[0032] Material outlet 5: Specifies the location of the equipment—below the unloading end of the belt conveyor. The material flow sample taken here best represents the material characteristics of the current conveying batch.

[0033] In summary, this equipment achieves precise linear reciprocating motion by driving a lead screw and nut (transmission seat) with a motor 21, and achieves smooth, low-resistance movement by using C-shaped guide rails and roller supports. Ultimately, it drives a sampling plate 11 with a splash guard to traverse the free-falling material flow at the unloading port of the conveyor head at high speed, thereby automatically, efficiently, safely, and representatively (especially the role of the baffle) intercepting samples of bulk materials such as cement mixtures. It is a key automatic sampling device for quality control in industries such as cement and building materials.
