[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-6 The belt automatic sampling machine shown includes a base 1, a guide hopper 2 for guiding materials is installed on the top of one end of the base 1, a belt conveyor frame 3 for material sampling and conveying is installed on the inner side of the base 1, and a dustproof mechanism 4 is provided on the surface of the belt conveyor frame 3.

[0025] The dustproof mechanism 4 includes a protective cover 41 and a limiting component 42. The limiting component 42 is arranged on both sides of the protective cover 41. There are two sets of limiting components 42, and each set of limiting components 42 has two components that are evenly distributed at both ends of the protective cover 41.

[0026] The base 1 serves as the foundation of the equipment, supporting the guide hopper 2 and the belt conveyor frame 3. The guide hopper 2 is responsible for guiding the material, and the belt conveyor frame 3 completes the material sampling and conveying. The material enters from the guide hopper 2 and then falls onto the belt conveyor frame 3. Subsequently, the material is conveyed to the designated position through the belt conveyor frame 3. At the same time, the dustproof mechanism 4 covers the belt conveyor frame 3 with a protective cover 41. Two sets (two in each set) of evenly distributed limiting components 42 on both sides fix the position of the protective cover 41, realizing the functions of dustproof and positioning of the protective cover 41.

[0027] Thus, dust is blocked by the dustproof mechanism 4. The two sets of symmetrically distributed limiting components 42 can not only fix the position of the protective cover 41, but also facilitate the opening and closing of the protective cover 41, ensuring the dustproof effect of the equipment on materials. At the same time, it is convenient for staff to operate during maintenance and shortens the operation time.

[0028] The protective cover 41 includes an outer arc plate 411 and an inner arc plate 412. The inner sidewall of the outer arc plate 411 is provided with a plurality of limiting grooves 413. The outer wall of the inner arc plate 412 is integrally formed with a limiting block 414 at the position corresponding to the limiting groove 413. The inner arc plate 412 and the outer arc plate 411 are slidably connected to each other through the cooperation of the limiting groove 413 and the limiting block 414.

[0029] The protective cover 41 adopts a combination structure of an outer arc plate 411 and an inner arc plate 412. Multiple limiting grooves 413 are preset on the inner side wall of the outer arc plate 411, and a limiting block 414 is integrally formed on the corresponding position of the outer wall of the inner arc plate 412. The limiting block 414 is embedded in the limiting groove 413 and can slide along the groove, so that the inner arc plate 412 can move telescopically relative to the outer arc plate 411 or the outer arc plate 411 can move telescopically relative to the inner arc plate 412. This sliding cooperation not only restricts the lateral offset of the outer arc plate 411 and the inner arc plate 412, but also allows them to adjust their relative positions along the length direction, thereby flexibly changing the overall coverage area of ​​the protective cover 41.

[0030] The inner and outer arc plates 411 are used in a sliding and telescopic cooperation, which can flexibly adjust the coverage area of ​​the protective cover 41 to ensure full or partial shielding of the belt conveyor frame 3, while also preventing dust generated by the belt conveyor frame 3 transporting materials.

[0031] The limiting component 42 includes two fixing plates 421, which are fixed to the top of the outer wall of the base 1. A first groove 422 is provided on the lower surface of the fixing plate 421. One end of the inner arc plate 412 and the outer arc plate 411 is installed on the fixing plate 421 and the base 1. A second groove 423 is provided at the contact position between the inner arc plate 412 and the outer arc plate 411 and the fixing plate 421. A slide seat 424 is provided in the first groove 422 and the second groove 423.

[0032] The limiting component 42 also includes a slider 425 integrally formed with the slide base 424. The slider 425 is located symmetrically within the slide base 424, and the slide base 424 is slidably connected to the slider 425 within the slide groove 422 and the slide groove 423.

[0033] Positioning pins 426 are movably connected to both ends of the upper surface of the slide block 424. Connecting blocks 427 are fixedly connected to the two opposing ends of the two positioning pins 426. Adjusting parts 428 that provide elastic force to the positioning pins 426 are installed on the connecting blocks 427. The lower end of the positioning pins 426 passes through the upper end of the slide block 425 inside the slide block 424 and extends downward. The inner arc plate 412 and the outer arc plate 411 are provided with insertion holes 429 that cooperate with the positioning pins 426. The fixed plate 421 is provided with insertion holes 4210 at the position corresponding to insertion holes 429. The lower end of the positioning pins 426 is inserted into insertion holes 429 and insertion holes 4210 in sequence.

[0034] When the protective cover 41 (inner arc plate 412, outer arc plate 411) is fixed above the belt conveyor frame 3 by the limiting component 42, the positioning pin 426 on the slide 424 is inserted into the first insertion hole 429 of the inner arc plate 412 and the outer arc plate 411 and the second insertion hole 4210 of the fixing plate 421 in turn under the elastic force of the adjusting component 428, so as to firmly lock the protective cover 41. The slide 424 is embedded in the first sliding groove 422 of the fixing plate 421 and the second sliding groove 423 of the protective cover 41 by the symmetrical slider 425, so as to ensure that the protective cover 41 does not shift during the vibration of the equipment operation, forming a stable dustproof closed space.

[0035] When maintenance is required on the belt conveyor frame 3, the maintenance personnel pull the positioning pin 426 upwards (simultaneously driving the two positioning pins 426 through the connecting block 427), compressing the adjusting component 428 to generate elastic reserve. The lower end of the positioning pin 426 disengages from the first insertion hole 429 and the second insertion hole 4210, releasing the lock on the protective cover 41. At the same time, the slide block 424 is removed from the surface of the first slide groove 422 and the second slide groove 423. Then, the protective cover 41 is pushed, causing the inner arc plate 412 to move relative to the outer arc plate 411. Move the cover open to expose the maintenance area of ​​the belt conveyor frame 3. After maintenance, push the protective cover 41 in the reverse direction to the closed position so that the first insertion hole 429 and the second insertion hole 4210 are aligned. Then slide the slide block 424 into the first slide groove 422 and the second slide groove 423. Then slide it to the position of the first insertion hole 429 and the second insertion hole 4210. The adjusting part 428 releases its elasticity and pushes the positioning pin 426 to re-insert into the first insertion hole 429 and the second insertion hole 4210, thus completing the fixing of the protective cover 41 and restoring the equipment to normal operation.

[0036] Through the rigid connection of the positioning pin 426, the first insertion hole 429, and the second insertion hole 4210, and the tight fit between the slider 425 and the first and second sliding grooves 422 and 423, the protective cover 41 is securely connected to the base 1 during operation, effectively resisting vibrations during equipment operation and ensuring a continuous and stable dustproof effect. Furthermore, the protective cover 41 does not require complete removal; it can be unlocked simply by pulling the positioning pin 426 and opened by pushing a portion of the protective cover 41. This simple operation significantly reduces maintenance preparation time, minimizes interruptions to sampling operations, and improves the overall operating efficiency of the equipment.

[0037] The synchronous linkage and elastic reset mechanism of the positioning pin 426 reduces the operating force and repetitive actions of maintenance personnel, reduces physical exertion during maintenance, and improves operational safety and comfort.

[0038] The adjusting component 428 includes a positioning rod 4281 movably connected to both ends of the connecting block 427. The lower end of the positioning rod 4281 is fixed to the upper surface of the slide block 424, and the upper end of the positioning rod 4281 is fixedly connected to a stop block 4282. A spring 4283 is sleeved on the surface of the positioning rod 4281 located between the connecting block 427 and the slide block 424. One end of the spring 4283 is fixedly connected to the connecting block 427, and the other end of the spring 4283 is fixedly connected to the slide block 424.

[0039] The positioning rod 4281 of the adjusting component 428 is fixed on the slide 424. The spring 4283 is sleeved on the positioning rod 4281 and its two ends are respectively connected to the connecting block 427 and the slide 424. In the natural state, the spring 4283 pushes the connecting block 427 to drive the positioning pin 426 to be inserted into the first insertion hole 429 and the second insertion hole 4210. When the positioning pin 426 is pulled, the spring 4283 is compressed. After being released, the spring 4283 returns to its original position and pushes the positioning pin 426 to be reinserted into the first insertion hole 429 and the second insertion hole 4210.

[0040] Spring 4283 provides stable elasticity to ensure that positioning pin 426 is tightly inserted, preventing positioning pin 426 from loosening and falling off during equipment operation; no additional fixing structure is required, positioning is achieved by automatic reset of spring 4283, simplifying operation steps, reducing the difficulty of operation for maintenance personnel, and improving the ease of use of equipment.

[0041] A fixing block 4284 is fixedly connected to the bend at the upper end of the positioning pin 426. The lower surface of the fixing block 4284 is attached to the upper surface of the slide 424. The insertion end of the positioning pin 426 is set in an arc shape.

[0042] The fixing block 4284 at the upper bend of the positioning pin 426 fits against the upper surface of the slide 424, limiting the offset of the positioning pin 426 when it is inserted or removed. The insertion end of the positioning pin 426 is set to be arc-shaped to reduce the frictional resistance when it is inserted into the socket, making it easier to insert accurately and quickly.

[0043] The fixing block 4284 improves the stability of the positioning pin 426 during insertion and removal, preventing damage to the socket during operation. The arc-shaped insertion end reduces the difficulty of insertion and removal, further improving the convenience of opening and closing the protective cover 41, reducing the workload of maintenance personnel, and extending the service life of equipment components.
