[0024] The present invention will be further described in detail below with reference to the accompanying drawings.
[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0026] like Figure 1As shown, a coal sampler includes a conveyor frame 1, on which several sets of idler roller assemblies are arranged. A conveyor belt is arranged on the idler roller assemblies, and a conveyor drive assembly is arranged on the conveyor belt. A sampling cam 2 is above the conveyor belt, and a sampling drive assembly is arranged on the sampling cam 2. A lifting assembly for controlling the raising and lowering of the sampling cam 2 is arranged on the sampling drive assembly. A sampling box 3 is also arranged on the conveyor frame 1. Several collection boxes 4 are arranged below the sampling box 3. A spill prevention cover 5 is slidably connected to the collection box 4. A support assembly is arranged at the bottom of the collection box 4, and a pushing assembly for pushing the collection box 4 to move.
[0027] The conveyor frame 1 provides support for the entire equipment. The lifting component raises and lowers the sampling cam 2 to a suitable height. During use, the conveyor drive component is the power source, and the coal is transported by the conveyor belt. During the transportation process, the sampling drive component drives the sampling cam 2 to rotate accordingly, so that the coal on the conveyor belt enters the sampling box 3. The bottom of the sampling box 4 is inclined, so that the sampled coal sample can be slid into the sampling box 4. During the sampling process, the push component moves the sampling box 4 on the support component. When the sampling box 4 moves to directly below the sampling box 3, the support component opens the spill cover 5, so that the collected coal sample can smoothly enter the sampling box 4. The sampling cam 2 performs multiple samplings. When there is enough sample in the sampling box 4, the push component works again to push the sampling box 4 out of the support component and make the next sampling box 4 slide directly below the sampling box 3.
[0028] like Figure 1 As shown, the sampling cam 2 has a sampling port 6 on the side facing the sampling box 3; through the sampling port 6, the collected coal sample can be temporarily stored in the sampling cam 2. As the sampling cam 2 rotates, the coal sample can make parabolic motion, leave the sampling cam 2 and enter the sample collection box 4.
[0029] like Figures 3 to 5 As shown, the top of the sample collection box 4 has two sliding grooves 7, which are symmetrically distributed along the center of the sample collection box 4. A sample collection slide 8 is slidably connected in each of the two sliding grooves 7. A spring 9 is fixedly connected to one side of each of the two sample collection slides 8. The two springs 9 are respectively fixedly connected to the inner wall of the two sample collection slots 13. The top of each of the two sample collection slides 8 is bolted to the anti-spill cover 5. The support assembly includes a support base plate 10, a support side plate 11 is provided on the support base plate 10, and a fixing rod 12 is provided on the support side plate 11. The fixing rod 12 is inserted into the sample collection slide 8 on one side of the support side plate 11. A sample collection slot 13 is provided on the sample collection slide 8 for the fixing rod 12 to be inserted.
[0030] The support base plate 10 provides corresponding support for the sample collection box 4. The sample collection box 4 is pushed by the pushing component, so that the sample collection box 4 can slide on the surface of the support base plate 10. The anti-spill cover 5 on the sample collection box 4 is normally closed and the spring 9 is relaxed. The sample collection slide 8 is pushed to the rightmost end. When the fixing rod 12 is inserted into the sample collection groove 13, the thrust of the fixing rod 12 pushes the sample collection slide 8 to slide. At the same time, the spring 9 is compressed and the anti-spill cover 5 is opened, so that the collected sample can enter the sample collection box 4.
[0031] like Figures 3 to 4 As shown, the pushing assembly includes a pushing disk 14, on which a plurality of pushing rods 15 are provided. A driving wheel 16 and a driven wheel 17 are respectively provided on the rotating shaft of the pushing disk 14. A pushing belt 18 is wound around the driving wheel 16 and the driven wheel 17. A pushing motor 19 is drivenly connected to the rotating shaft of the driving wheel 16. The pushing motor 19 is fixed to the conveyor frame 1 by a pushing seat bolt.
[0032] The push rod 15 on the push disc 14 can fix the sample collection box 4 and push the sample collection box 4 to a certain position. The push motor 19 is the driving source, which drives the active rotating wheel 16 to rotate and causes the push disc 14 on the active rotating wheel 16 to rotate accordingly. The active rotating wheel 16 can drive the driven rotating wheel 17 to rotate accordingly through the push belt 18, and push the sample collection box 4 fixed on the push disc 14 accordingly.
[0033] like Figures 1 to 2 As shown, the sampling drive assembly includes a sampling motor 20, a sampling gear 21 is provided on the output shaft of the sampling motor 20, the sampling gear 21 is connected to the sampling cam 2, the sampling cam 2 is provided with a cam groove that meshes with the sampling gear 21, and the sampling motor 20 is connected to the lifting assembly through the sampling seat; the lifting assembly includes a lifting cylinder 22, a lifting connecting plate 23 is provided on the piston rod of the lifting cylinder 22, a lifting base plate 24 is provided on the lifting connecting plate 23, the lifting base plate 24 is bolted to the sampling seat, and several lifting slides are bolted to one side of the lifting base plate 24. The lifting slides are slidably connected to two lifting slide rails, and each of the two lifting slide rails is provided with a slide rail seat.
[0034] The lifting cylinder 22 can drive the lifting connecting plate 23 to rise and fall. The rising and falling of the lifting connecting plate 23 can drive the lifting base plate 24 to rise and fall accordingly, so that the sampling drive assembly is moved to a suitable height, which is convenient for sampling the material on the conveyor belt. The lifting slide and the lifting slide rail play a guiding and supporting role, so that the lifting base plate 24 can rise and fall in a predetermined direction during the lifting process. The sampling motor 20 is the power source, and its output shaft drives the sampling gear 21 to rotate. Through the meshing of the sampling gear 21 with the cam groove, the sampling cam 2 rotates accordingly to complete the sampling work.
[0035] Working principle: The sampling cam 2 is moved to a suitable height by the lifting cylinder 22, and the coal sample is transported by the conveyor belt. During the transportation process, the sampling motor 20 drives the sampling gear 21 to rotate through its output shaft. The rotation of the sampling gear 21 drives the sampling cam 2 to rotate, and the sampling cam 2 can collect the coal sample on the conveyor belt. The collected coal sample can be slid into the sample collection box 4. During the sampling process, the push motor 19 drives the push disk 14 to rotate, so that the sample collection box 4 can slide on the support base plate 10. When the sample collection box 4 is moved directly below the sampling box 3, the thrust of the fixed rod 12 pushes the sample collection slide 8 to slide. At the same time, the spring 9 is compressed, the spill cover 5 is opened, and the collected sample can enter the sample collection box 4. The sampling cam 2 performs multiple samplings. When there is enough sample in the sample collection box 4, the push disk 14 works again to push the sample collection box 4 out of the support base plate 10 and make the next sample collection box 4 slide directly below the sampling box 3.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
