[0029] This utility model provides a detection and analysis device, such as... Figures 1-6As shown, a solid waste detection and analysis device for improving detection accuracy includes a crushing box 1, a crushing component fixedly installed on one side of the crushing box 1, a protective component fixedly connected to the top of the outer surface of the crushing box 1, a first screening screen 2 fixedly connected to the bottom of the inner side wall of the crushing box 1, and an adjustment component fixedly connected to the lower surface of the crushing box 1.

[0030] The protective assembly includes a guide plate 3, the inner side of which is fixedly connected to the top of the outer surface of the crushing box 1. A first cylinder 4 is fixedly connected to one side of the guide plate 3. A dust collection box 5 is fixedly connected to the output end of the first cylinder 4. An exhaust fan 6 is fixedly installed on one side of the dust collection box 5. A sealing cover 7 is fixedly connected to the lower surface of the dust collection box 5. When the first cylinder 4 is activated, it pushes the sealing cover 7 to move along the guide plate 3, thereby sealing the opening of the crushing box 1 to prevent solid waste from splashing during the crushing process and causing safety hazards to surrounding personnel and equipment. Subsequently, the exhaust fan 6 is activated to absorb the dust generated during the crushing process into the dust collection box 5 for storage, preventing it from being scattered into the air and affecting the working environment.

[0031] The crushing assembly includes a first motor 8, one side of which is fixedly installed on one side of the crushing box 1. A first gear 9 is fixedly connected to the output end of the first motor 8. A second gear 10 meshes with the outer surface of the first gear 9. Crushing rollers 11 are fixedly connected to the inner sides of both the first gear 9 and the second gear 10. When the first motor 8 is started by an external power source, the first gear 9 drives the second gear 10 to rotate relative to each other, thereby causing the crushing rollers 11 to rotate relative to each other and crush the solid waste so that its particle size meets the testing standards.

[0032] The adjustment assembly includes a support plate 12, the upper surface of which is fixedly connected to the lower surface of the crushing box 1. A second cylinder 13 is fixedly connected to one side of the support plate 12, and a second sieve 14 is fixedly connected to the output end of the second cylinder 13. When the second cylinder 13 is activated, it drives the second sieve 14 to move relative to the first sieve 2, thereby misaligning the sieve holes and adjusting the size of the sieve holes so that the crushed solid waste can fall onto the calorific value tester 18 for testing. This effectively ensures the quality of crushing, obtains qualified particle size, and improves the accuracy of the test data.

[0033] A surrounding plate 15 is fixedly connected to the lower surface of the support plate 12. A funnel 16 is fixedly connected to the top of the inner side wall of the surrounding plate 15. The funnel 16 facilitates the entry of the solid waste screened by the first screening screen 2 and the second screening screen 14 into the calorific value tester 18 for testing.

[0034] A placement plate 17 is fixedly connected to the bottom of the inner side wall of the enclosure 15. A calorific value tester 18 is provided on the upper surface of the placement plate 17. The placement plate 17 facilitates the placement of the calorific value tester 18, which can test solid waste.

[0035] The lower surface of the enclosure 15 is fixedly connected with a support leg 19. The front and back of the enclosure 15 are provided with access ports, which facilitate the removal of solid waste after testing by the calorific value tester 18 for the next use.

[0036] There are two dust collection boxes 5 connected together. A through groove is provided on the upper surface of the sealing cover 7 and the lower surface of one of the dust collection boxes 5. The through groove facilitates the entry of dust into the dust collection box 5. The through connection of the two dust collection boxes 5 can prevent dust from flowing back into the crushing box 1 and ensure the dust removal effect.

[0037] Working steps: First, start the first cylinder 4 to push the sealing cover 7 along the guide plate 3 to close the opening of the crushing box 1. Next, start the first motor 8 with the external power supply. The first gear 9 drives the second gear 10 to rotate relative to each other, so that the crushing roller 11 rotates relative to each other to crush the solid waste. Next, start the exhaust fan 6 to absorb the dust generated during the crushing process into the dust collection box 5 for storage to prevent it from being scattered into the air. Finally, start the second cylinder 13 to drive and control the second screening screen 14 to move relative to the first screening screen 2, so that the screen holes of the two are misaligned and the size of the screen holes is adjusted so that the crushed solid waste can fall above the calorific value tester 18 for testing.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
