Detailed Description of the Preferred Embodiment

[0026] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0027] Refer toFigure 1 and Figure 2 The utility model provides a sampling device for a particle analysis detector, including a conveyor belt 1, an extraction mechanism 2 and a material conveying mechanism 3 are arranged on the top of the conveyor belt 1, a material guide table assembly 4 is connected to the output end of the material conveying mechanism 3, the extraction mechanism 2, the material conveying mechanism 3, and the material guide table assembly 4 are all fixed on the ground, the material guide table assembly 4 is used to collect the material output by the material conveying mechanism 3, and guide the material to the detection instrument, and the material guide table assembly 4 is also used for air drying the material;

[0028] The extraction mechanism 2 includes a fixed frame 21, a hanging plate 23 is fixedly installed on the top of the fixed frame 21 through two transverse movement mechanisms 22, an electric cylinder 24 is fixedly installed on the top of the hanging plate 23, and the output end of the electric cylinder 24 passes through the hanging plate 23 and is connected to a lifting component 25.

[0029] Reference Figure 2 A positioning rod 26 is fixedly connected to the top of the lifting assembly 25, and the top of the positioning rod 26 penetrates to the top of the hanging plate 23. By setting the positioning rod 26, the stability of the lifting assembly 25 during vertical lifting can be improved.

[0030] Reference Figure 3 The material lifting component 25 includes a hanging plate 251, and the bottom of the hanging plate 251 is fixedly connected to each ear plate 252 of the chain. The inner sides of the two ear plates 252 are installed with a material lifting cabin 253. An electric cylinder 254 is installed inside the material lifting cabin 253. The output shaft of the electric cylinder 254 is fixedly connected to a push plate 255. The push plate 255 is slidably sleeved inside the material lifting cabin 253. One side of the material lifting cabin 253 is set to be an opening. When the material lifting component 25 descends to the top of the conveyor belt 1, the conveyed material can be intercepted by the material lifting cabin 253, and the material enters the interior of the material lifting cabin 253 from the opening on one side of the material lifting cabin 253. When the material lifting component 25 outputs the material, the push plate 255 is driven to slide inside the material lifting cabin 253 through the operation of the electric cylinder 254, so that the sample material can be pushed out, thereby achieving the effect of the material lifting component 25 outputting the sample.

[0031] Reference Figure 3 The front and back sides of the material lifting cabin 253 are fixedly connected with swivel columns 258, and the two swivel columns 258 are movably connected on the inner sides of the two ear plates 252. The bottom of the second hanging plate 251 and the top of the material lifting cabin 253 are fixedly connected with a connecting frame 256, and the two connecting frames 256 are connected by transmission through the telescopic rod 257. When the conveyor belt 1 has a certain slope, the material lifting assembly 25 is in a horizontal state and its opening cannot fit with the top of the conveyor belt 1, and the material cannot be intercepted. At this time, the telescopic rod 257 is extended and retracted to make the swivel columns 258 rotate on the inner sides of the two ear plates 252, thereby adjusting the inclination of the material lifting cabin 253, so that the material lifting assembly 25 can be adapted to the conveyor belts 1 with different slopes, and the use of the material lifting assembly 25 has a higher matching degree.

[0032] ReferenceFigure 4 The telescopic rod 257 includes an outer cylinder 2571 and a threaded rod 2572. The threaded rod 2572 is threadedly sleeved on the inner wall of the outer cylinder 2571. Connecting rings 2573 are movably sleeved on the outer ends of the outer cylinder 2571 and the threaded rod 2572. The two connecting rings 2573 can rotate along the central axes of the outer cylinder 2571 and the threaded rod 2572. The two connecting rings 2573 are respectively movably sleeved on the side walls of the two connecting brackets 256. By rotating the outer cylinder 2571, due to the threaded cooperation relationship between the outer cylinder 2571 and the threaded rod 2572, the telescopic rod 257 can achieve the telescopic effect.

[0033] Refer to Figure 5 The material conveying mechanism 3 includes a material conveying cylinder 31, a spiral blade rod 32, a feed hopper 33, and a motor 34. The spiral blade rod 32 is movably sleeved inside the material conveying cylinder 31. A feeding groove is provided at the top of the material conveying cylinder 31. The feed hopper 33 is fixedly connected in the feeding groove. The output shaft of the motor 34 penetrates through the material conveying cylinder 31 and is connected to the spiral blade rod 32. A discharge pipeline 37 is provided at the bottom of the material conveying cylinder 31. The discharge pipeline 37 is communicated with the inside of the material conveying cylinder 31. The material conveying cylinder 31 is supported on the ground by two support plates 35. The bottom of the material conveying cylinder 31 is supported on the top of the material guiding table assembly 4 by a support block 36. When the feeding assembly 25 outputs sample particles, the samples fall into the inside of the feed hopper 33. The samples inside the feed hopper 33 enter the inside of the material conveying cylinder 31 through the feed hopper 33. The motor 34 outputs power to drive the spiral blade rod 32 to rotate, thereby spirally conveying the granular samples. The materials conveyed inside the material conveying cylinder 31 fall and are output through the discharge pipeline 37.

[0034] Refer to Figure 6 The material guiding table assembly 4 includes a main table body 41. A hole penetrating through to the bottom is opened at the top of the main table body 41. A material guiding hopper assembly 44 is fixedly connected inside the hole. A frame plate 42 is fixedly connected to the top of the main table body 41 at the position of the hole. An intercepting plate 43 is slidably sleeved inside the frame plate 42. A scraping plate 45 is fixedly connected to one side of the inner wall of the frame plate 42. The bottom of the scraping plate 45 is attached to the top of the intercepting plate 43. An electric cylinder three 46 is fixedly installed on the top of the main table body 41. One side of the intercepting plate 43 penetrates through the side wall of the frame plate 42 and is connected to the output shaft of the electric cylinder three 46. A hot air blower 48 is provided on the top of the main table body 41. The output end of the hot air blower 48 is communicated with the inside of the frame plate 42 through a duct 47. The sample particles output by the material conveying mechanism 3 fall into the inside of the frame plate 42 and are intercepted by the intercepting plate 43. At this time, hot air is output by the hot air blower 48 and enters the inside of the frame plate 42. Thus, the granular materials intercepted on the top of the intercepting plate 43 can be dried. Then, the electric cylinder three 46 operates to drive the intercepting plate 43 to slide, so that the intercepting plate 43 moves outward from the frame plate 42. At this time, the sample particles on the top of the intercepting plate 43 come into contact with the scraping plate 45. The scraping plate 45 has a pushing effect on the sample particles. The sample particles fall into the inside of the material guiding hopper assembly 44. The granular materials are guided into the detection instrument through the material guiding hopper assembly 44.

[0035] Reference Figure 7 , the material guiding table assembly 4 includes a main hopper body 441. At the bottom ends on both sides of the main hopper body 441, there are two discharge end pipes 442. The two discharge end pipes 442 are communicated with the inside of the main hopper body 441. The sample particles entering the inside of the material guiding hopper assembly 44 are located inside the main hopper body 441. The particles inside the main hopper body 441 can be output through the two discharge end pipes 442. By providing the two discharge end pipes 442, the material guiding hopper assembly 44 is convenient for guiding the sample material to different detection instruments or devices.

[0036] The working principle of the present utility model: When in use, the granular material is conveyed by the conveyor belt 1. During this process, the sample of the granular material is extracted by the extraction mechanism 2. The process is that the electric cylinder 1 24 outputs to drive the material lifting assembly 25 to move downward, so that the material lifting assembly 25 contacts the top of the conveyor belt 1, thereby intercepting and collecting part of the granular material through the material lifting assembly 25 to achieve the effect of extracting the sample. Then, the electric cylinder 1 24 drives the material lifting assembly 25 to rise and return to its position. The hanging plate 1 23 is driven by the transverse movement mechanism 22 to move transversely so that the material lifting assembly 25 reaches the top of the material conveying mechanism 3. Then, the collected sample is output through the material lifting assembly 25. The sample drops into the inside of the material conveying mechanism 3. The material conveying mechanism 3 conveys the sample into the inside of the material guiding table assembly 4. The material guiding table assembly 4 guides the sample into the detection instrument and air-dries the sample, thereby achieving the effect of automatic sampling.
