[0018] Please refer to Figure 1-7 , the embodiments of the present invention provide a technical solution: a dust suppression hopper system, including a support frame structure, a hopper structure arranged inside the support frame structure, a grid structure arranged at the top opening of the hopper structure, and a dust removal structure evenly distributed on the outer wall of the top of the hopper structure. The dust removal structure is inclined and forms an angle of 50-55 degrees with the horizontal, which is convenient for dust suction operation. A windshield 1 is arranged at the top of the hopper structure, and the windshield 1 is detachably connected to the hopper structure. The hopper structure includes a hopper frame 2, and a chute cylinder 3 is detachably connected to the discharge port at the bottom of the hopper frame 2. A vibrator 4 is arranged on the outer wall near the discharge port at the bottom end of the hopper frame 2. The dust removal structure is inclined and the output end extends into the hopper frame 2. The dust removal structure includes a power box 5, and a filter cartridge skeleton 6 is connected to the outside of the power box 5. A plurality of filter pipes 7 are arranged at equal intervals at the bottom end of the filter cartridge skeleton 6 in a row. A fan is arranged inside the power box 5, and an ash discharge hood 8 is also arranged at the outer end of the power box 5.

[0019] A plurality of adsorption holes 9 are opened on the side wall of the power box 5, and a filter net 10 is embedded in the adsorption holes 9 to improve the effect of adsorbing dust and floating dust through the adsorption holes 9.

[0020] The support frame structure includes a horizontal lower shelf plate 11 and an upper shelf plate 12. A plurality of load-bearing rods 13 vertically penetrate through the upper shelf plate 12 and the lower shelf plate 11. An operation platform 14 is connected to the top end of the load-bearing rod 13. A steel frame ladder 15 is arranged outside the support frame structure. Supported and reinforced by using the lower shelf plate 11 and the upper shelf plate 12, the steel frame ladder 15 is convenient for operators to walk and is easy to maintain and repair the equipment.

[0021] A hydraulic cylinder 16 is provided at the bottom of the edge of the lower shelf plate 11, and a reinforcing rod 17 is obliquely connected to the top of the lower shelf plate 11 in series. The tops of several reinforcing rods 17 are jointly connected to a top shelf plate 18. The outer side of the top shelf plate 18 is connected to the load-bearing rod 13. A driving wheel 19 is connected to the bottom end of the load-bearing rod 13. The hydraulic cylinder 16 is used to adjust the up and down height of the equipment, facilitating the transfer equipment at the bottom to pass through.

[0022] The grille structure includes a light grille plate 20. The light grille plate 20 is arranged at the feeding port of the funnel frame 2. And a heavy grille 21 is arranged inside the light grille plate 20. The light grille is at the bottom of the windshield. A light grille with an opening size of about 200mm×200mm needs to be configured above the feeding port of the hopper to prevent large lumpy materials or sundries from entering the hopper or downstream equipment and causing damage. For the heavy grille, the support structure of the light grille needs to be able to bear the weight of an empty grab bucket (16t) and protect the lower curtain system from accidental impacts during grab bucket unloading.

[0023] A support rod 22 is arranged at the top of the heavy grille 21. The top of the support rod 22 is connected to the light grille plate 20. A curtain structure is arranged at the bottom of the heavy grille 21. The hopper is equipped with a curtain system to reduce the overflow of dust-containing air during grab bucket unloading. The curtain system adopts a modular design and is divided into a steel lining plate and a rubber curtain. One side of the curtain is fixed to the steel lining plate and the other side is movable. The flexible curtain is made of highly wear-resistant food-grade rubber according to the material properties. The steel scouring surface affected by the material impact needs to be configured with an NM500 lining plate with a thickness of not less than 8mm. And both the flexible curtain and the wear-resistant lining plate need to be easy to replace. When the goods fall from the hopper opening, the gravity of the goods presses open the rubber curtain of the flexible curtain. The goods pass through the curtain. After passing through, the rubber curtain returns to its position, blocking the passage, so that the dust cannot rise back through the curtain.

[0024] In the first embodiment, the curtain structure includes several steel lining plates 23. The steel lining plates 23 are connected to the inner wall of the funnel frame 2. And a detachable rubber curtain 24 is connected to the inner side of the steel lining plates 23. The elastic and flexible rubber curtain 24 can be used to promote the passage of raw materials and can be reset.

[0025] In the second embodiment, the curtain structure includes four connecting plates 25. A rotatable shaft rod 26 is arranged on the inner wall of the connecting plates 25. And lead screws 27 are connected to both ends of the shaft rod 26. A torsion spring 28 is wound around the outer side of the shaft rod 26. The shaft rod 26 and the two lead screws 27 form a sector. And a detachable rubber sheet 29 is arranged inside. By utilizing the elastic force of the torsion spring 28, the rubber sheet 29 is urged to reset along the lead screw 27.

[0026] A load-bearing plate 30 is arranged at the top of the middle position of the lower shelf plate 11. A control cabinet 31 is arranged on the top of the load-bearing plate 30. The control cabinet 31 is used to control the equipment as a whole.

[0027] Working principle: The support structure externally supports and fixes the entire hopper structure. At the same time, the grille structure can prevent dust from flying inside. A wind shield 1 is provided at the top of the hopper structure to avoid dust flying during unloading. At the same time, the grab bucket can be placed on the top of the grille structure to avoid suspended operation. The light grille plate 20 can screen the raw materials, and the heavy grille 21 at its bottom plays an overall load-bearing effect. When the material passes through and enters the curtain structure, elastic buffering can be carried out, and then it slowly slides down and falls, and is discharged through the chute cylinder 3 and sent to the loading equipment. The curtain structure can adopt a steel lining plate 23 and a rubber curtain, or a curtain structure composed of four connecting plates 25. A rotatable shaft rod 26 is provided on the inner wall of the connecting plate 25, and screw rods 27 are connected to both ends of the shaft rod 26. A torsion spring 28 is wound around the outer side of the shaft rod 26. The elastic force of the torsion spring 28 is used to promote the reset of the screw rod 27 and the rubber sheet 29, thereby buffering the falling of the material and reducing dust. The support structure can lift the entire equipment through the hydraulic cylinder 16, and can drive the entire equipment to move through the driving wheel 19. The dust removal structure includes a power box 5, and a filter cartridge skeleton 6 is connected to the outside of the power box 5. A number of filter pipes 7 are arranged at equal intervals at the bottom end of the filter cartridge skeleton 6 and are distributed in rows and penetrate into the inside of the funnel frame 2 to effectively suck out more dust. A fan is provided inside the power box 5, and an ash discharge cover 8 is also provided at the outer end of the power box 5. A number of adsorption holes 9 are opened on the side wall of the power box 5, and filter nets 10 are embedded in the adsorption holes 9 to improve the effect of adsorbing dust, and the dust flying during the overall unloading process is greatly reduced.
