Description

Technical Field

[0001] This invention relates to the field of sampling machine technology, specifically to a fully automatic belt sampling machine and its usage method. Background Technology

[0002] Fully automatic belt sampling machines are the most common type of sampling equipment. Their working principle involves a motor-driven sampling head that rotates and oscillates against the belt surface to sample the material across the entire cross-section. However, this type of sampling machine has the following drawbacks in practical applications: 1. The rotary sampling head requires a large space to operate, resulting in a bulky device. Furthermore, the sampling head experiences significant material resistance during operation, necessitating a high-power motor and thus increasing equipment costs. 2. Due to the fixed structure of the sampling head, the sample volume per operation is constant, making it unsuitable for diverse sampling needs. 3. When unloading the sample from the sampling head, it relies solely on gravity, which can easily lead to clogging, especially with materials that are highly moist or viscous. 4. The rotary sampling head samples material by scraping, causing significant damage to the belt at the tip.

[0003] Therefore, a fully automatic belt sampling machine and its usage method are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic belt sampling machine and its usage method, so as to overcome the shortcomings of the prior art, such as large equipment size, high equipment cost, easy material blockage, and significant damage to the belt during sampling.

[0005] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, the present invention provides a fully automatic belt sampling machine, comprising a housing; the housing is disposed on a belt conveyor, a sampling component is installed on the housing, a scraping component is disposed above the sampling component and is mounted on the housing; the sampling component includes a hydraulic rod, which is fixedly connected to the housing, a connecting rod is connected to the output end of the hydraulic rod, a first connecting shaft is fixedly connected to the connecting rod, a first housing is fixedly connected to the first connecting shaft, and both the first housing and the first connecting shaft are fixedly connected to the housing, a second housing is fixedly connected to the first housing, and side plates are fixedly connected to the outer walls on both sides of the second housing, and the side plates are slidably connected inside the housing.

[0006] Furthermore, the housing has through holes, and both ends of the first housing are hinged to the through holes. A feed pipe is fixed to the housing at the position corresponding to the through holes, and one end of the first housing is rotatably connected to the feed pipe.

[0007] Furthermore, a motor is fixedly connected to the conveying pipe, and a second connecting shaft is fixedly connected to the output end of the motor. The second connecting shaft is rotatably connected to the first housing, and a spiral blade is fixedly connected to the second connecting shaft, with the spiral blade sleeved inside the first housing.

[0008] Furthermore, the first housing has a feed inlet located at the first end of the second housing, and the first housing has a discharge outlet located at the position of the conveying pipe.

[0009] Furthermore, a first elastic bending plate is fixedly connected to the second end of the second housing, and there are first elastic bending plates on both sides of the first elastic bending plate, and a second elastic bending plate is fixedly connected to the side plate.

[0010] Furthermore, a first drive roller is rotatably connected to one end of the second housing near the first housing, and a conveyor belt is slidably connected to the second housing. The two ends of the conveyor belt are respectively connected to a first drive roller and a second drive roller, and both the first drive roller and the second drive roller are rotatably connected to the second housing.

[0011] Furthermore, both ends of the second transmission roller are fixedly connected to a first gear, and a second gear is meshed with each of the first gears. A third connecting shaft is fixedly connected to the second gear, and a first roller is fixedly connected to the third connecting shaft. Mounting plates are fixedly connected to both outer walls of the second housing, and the first end of the third connecting shaft is hinged to the mounting plate. A sealing plate is fixedly connected to the mounting plate, and the second end of the third connecting shaft is hinged to the sealing plate. Both ends of the second transmission roller are respectively hinged to the two sealing plates.

[0012] Furthermore, a guide plate is fixedly connected to the second housing, and a scraping assembly is connected to the top of the guide plate. The scraping assembly includes two guide rods, and a slider is slidably connected to the two guide rods. A fixing block is fixedly connected to the guide rods and is fixedly connected to the housing. A spring is sleeved on the guide rod, with one end of the spring set on the slider and the other end set on the fixing block. A wheel seat is fixedly connected to the slider, and a second roller is hinged to the wheel seat. The second roller is set at the top of the guide plate. A spring sheet is fixedly connected to the wheel seat, and a scraper is fixedly connected to the spring sheet.

[0013] Furthermore, an avoidance groove is provided on the scraper at the position corresponding to the guide plate.

[0014] Secondly, the present invention provides a method for using a fully automatic belt sampling machine, comprising the following steps: The casing is mounted on a belt conveyor, which is used to transport materials. When sampling is performed, the sampling assembly is activated, and the hydraulic rod drives the second housing to deflect, performing a slanted shovel sampling. After sampling is completed, the sampling component is turned off. At this time, the scraping component scrapes off the residual material on the first housing, thus completing the sampling.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention provides a fully automatic belt sampling machine. The sampling component utilizes a hydraulic rod to drive the second housing to deflect, thereby achieving oblique shovel sampling. Compared to traditional sampling methods, this design requires less operating space and is adaptable to the space-constrained environment of belt conveyors, greatly enhancing the equipment's environmental adaptability. Simultaneously, it eliminates the need for a high-power motor, reducing energy consumption and the configuration of large components such as motors, fundamentally achieving miniaturization and weight reduction, lowering manufacturing costs and simplifying installation and maintenance. The sampling volume per pass can be controlled by adjusting the oblique shovel sampling time, meeting diverse sampling needs. This invention also includes a scraping component for material discharge, solving the problem of material blockage at the sampling head. The scraping component is linked to the sampling component; after the sampling component completes its sampling action, the scraping component operates synchronously via a mechanical transmission structure during the hydraulic rod-driven second housing reset or the next sampling action, eliminating the need for an additional power source. This integrated, linked design not only simplifies the equipment's power system architecture and reduces energy consumption but also fundamentally lowers manufacturing costs. In actual operation, the scraping component can promptly scrape off the material adhering to the inner wall of the sampling head or in the sampling channel, ensuring the unobstructed flow of the sampling channel and effectively avoiding problems such as sampling errors and equipment failures caused by material blockage.

[0016] Furthermore, the cooperation between the first and second housings in the sampling assembly, as well as the arrangement of the conveying pipe and spiral blades, further optimizes the sampling process. The connection between the inlet on the first housing and the second housing ensures that materials can smoothly enter the sampling channel; driven by the motor, the spiral blades can evenly and efficiently transport the collected materials to the outlet, avoiding material accumulation and blockage, and improving the continuity and efficiency of sampling. The first and second elastic bending plates on the second housing not only effectively prevent material spillage but also buffer material impact to a certain extent, protecting the equipment structure and extending the service life of the equipment.

[0017] Furthermore, in terms of material transport, the conveyor belt inside the second housing, in conjunction with the first and second drive rollers, achieves stable material transport. The meshing transmission of the first and second gears, along with the third connecting shaft and the first roller, provides stable power to the conveyor belt.

[0018] Furthermore, when the sampling assembly is running, the movement of the second housing drives the second roller of the scraping assembly via the guide plate, which in turn causes the slider to slide on the guide rod. The elasticity of the spring ensures a tight fit between the scraper and the inner wall of the sampling channel, and also provides cushioning when encountering significant resistance, preventing equipment damage. Under the action of the spring, the scraper can promptly scrape off the material adhering to the inner wall of the sampling head, the conveyor belt, and the sampling channel, effectively solving the problem of material blockage during the sampling process.

The spring piece 37 on the slider 34 provides the scraper 38 with the spring force, so that the scraper 38 can fit against the second housing 210 and the side plate 211. The slider 34 drives the scraper 38 to push the material on the second housing 210. Under the weight of the material and the push of the scraper 38, the material enters the first housing 24 through the feed port 25.

[0038] Example 3 This invention also provides a method for using a fully automatic belt sampling machine, comprising the following steps: The casing 1 is installed on the belt conveyor 4, and the belt conveyor 4 is used to transport materials. When sampling is performed, sampling component 2 is activated, and hydraulic rod 21 drives second housing 210 to deflect, performing inclined shovel sampling; After sampling is completed, the sampling component 2 is turned off. At this time, the scraping component 3 scrapes off the residual material on the first housing 24, thus completing the sampling.

[0039] Specific principle: When using this invention, the housing 1 is installed on the belt conveyor 4, and the belt conveyor 4 is used to transport materials. When sampling is required, the hydraulic rod 21 can be activated. The hydraulic rod 21 extends and drives the first connecting shaft 23 via the connecting rod 22. The first housing 24 on the first connecting shaft 23 deflects accordingly, and the second housing 210 on the first housing 24 also deflects accordingly. The end of the second housing 210 is obliquely inserted into the transported material. The first elastic bending plate 222 at the end of the second housing 210 and the second elastic bending plate 223 at the end of the side plate 211 contact the belt conveyor. The belt 4, with the first roller 220 also in contact with the belt, allows the material being conveyed to be scooped up by the second housing 210. The belt drives the first roller 220, causing it to rotate. This rotation, via the third connecting shaft 219, drives the second gear 218. The second gear 218, through the first gear 217, drives the second transmission roller 216. The second transmission roller 216 then drives the conveyor belt 215, which in turn drives the first transmission roller 214. The conveyor belt 215 continues to transport the material scooped up by the second housing 210 upwards into the first housing 24, ensuring that subsequently scooped material can be continuously fed into the first housing 24. In this process, the sampling amount can be controlled by controlling the contact time between the second housing 210 and the belt conveyor 4. After sampling is completed, the hydraulic rod 21 retracts, causing the second housing 210 to reverse and reset. During this process, the guide plate 221 pushes the second roller 36, which drives the slider 34 via the wheel seat 35. The slider 34 slides along the guide rod 32 and, in conjunction with the fixing block 31, compresses the spring 33. The spring piece 37 on the slider 34 provides elasticity to the scraper 38, allowing the scraper 38 to adhere to the second housing 210 and the side plate 211. The slider 34 drives the scraper 38 to push the second housing 210. The material on the housing 210, under its own weight and the push of the scraper 38, enters the first housing 24 through the feed port 25. Then the motor 27 is started, and the spiral blades 29 are driven through the second connecting shaft 28. The spiral blades 29 send the material in the first housing 24 into the discharge port 26, and then fall into the conveying pipe 12 to enter the next process. The through hole 11 is used to accommodate the first housing 24, the mounting plate 212 and the sealing plate 213 are used to protect the second gear 218, the spring 33 is used to provide the reset force for the slider 34, and the clearance groove 39 is used to avoid the guide plate 221.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
