Technical Field

[0001] The utility model relates to the technical field of fine granular material feeding, in particular to a fine granular material dust-proof feeding mechanism. Background Art

[0002] Fine aggregate refers to granular materials with smaller particle size and finer particle diameter. It is usually made by crushing, grinding or artificial preparation of natural ore. Fine aggregate is widely used in building materials, concrete, asphalt, cement mortar and other fields.

[0003] However, when the existing fine particles are transported to a certain location for processing, a large amount of dust is likely to occur, which is easy for workers to inhale and is very harmful to the body. The existing method usually uses a suction fan and a filter to absorb the dust generated when the fine particles are fed. However, this method easily causes the filter to become blocked, affecting the dust collection effect. Utility Model Content

[0013] Preferably, a feed port is provided on the left inner wall of the feed bin, a suction pipe is fixedly connected to the surface of the suction fan, and one end of the suction pipe away from the suction fan is fixedly connected to a dust hood.

[0014] Compared with the prior art, the utility model provides a dust-proof feeding mechanism for fine particles, which has the following beneficial effects:

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 5 A dust-proof feeding mechanism for fine particles includes a feeding bin 1 and a suction fan 2 arranged on the right side of the feeding bin 1, a motor 3 is fixedly arranged at the bottom of the feeding bin 1, a dust cover 4 is arranged on the top inner wall of the feeding bin 1, and a filter screen 5 is fixedly connected to the bottom surface of the dust cover 4, and also includes: a rotating rod 6, which is fixedly connected to the output end of the motor 3; a convex block 7, which is fixedly connected to the top of the rotating rod 6; a fixed plate 8, which is fixedly connected to the left inner wall of the feeding bin 1; a collision rod 9, which is slidably connected to the fixed plate 8 The arc plate 10 is fixedly connected to the bottom of the collision rod 9, and the motor 3 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the protrusion 7 to rotate and contact the arc plate 10. The arc plate 10 can drive the collision rod 9 to slide upward on the fixed plate 8 along the arc surface of the arc plate 10, thereby driving the collision rod 9 to collide with the bottom of the filter screen 5, so that the fine particles stuck on the surface of the filter screen 5 can collide and fall off, thereby preventing the filter screen 5 from being blocked, so that the suction fan 2 can absorb dust better and more efficiently.

[0026] The rotating rod 6 passes through the bottom of the feeding bin 1 and is rotatably connected to the feeding bin 1 . The feeding bin 1 can support the rotating rod 6 , which helps to make the rotating rod 6 rotate stably.

[0027] The protrusion 7 is slidably connected to the arc plate 10. When the protrusion 7 rotates and contacts the arc surface of the arc plate 10, the arc plate 10 can slide upward. The reciprocating contact can make the arc plate 10 slide up and down reciprocatingly.

[0028] The collision rod 9 passes through the right end of the fixing plate 8 and is slidably connected to the fixing plate 8. The fixing plate 8 can support and guide the collision rod 9 to prevent the collision rod 9 from deflecting.

[0029] A return spring 11 is sleeved on the surface of the collision rod 9, one end of the return spring 11 is fixedly connected to the bottom of the fixed plate 8, and the other end of the return spring 11 is fixedly connected to the arc plate 10. When the arc plate 10 slides upward, the collision rod 9 can be driven to compress the return spring 11. When the protrusion 7 does not conflict with the arc plate 10, the return spring 11 can automatically reset the arc plate 10.

[0030] A bevel gear 12 penetrates the surface of the rotating rod 6 and is fixedly connected to the rotating rod 6. A discharge port is opened on the inner wall on the right side of the bottom of the feeding silo 1. A spiral conveying roller 13 is rotatably connected in the discharge port of the feeding silo 1. The left end of the spiral conveying roller 13 is fixedly connected to a bevel gear 2 14, which meshes with the bevel gear 1 12. A dustproof frame 15 is fixedly sleeved on the surface of the feeding silo 1 near the bevel gear 12 and the bevel gear 2 14. The motor 3 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the bevel gear 12 to mesh with the bevel gear 2 14, so that the spiral conveying roller 13 can rotate, which is convenient for orderly conveying of the fine particles in the feeding silo 1. The dustproof frame 15 can prevent the material from affecting the rotation of the bevel gear 12 and the bevel gear 2 14.

[0031] A discharge pipe 16 is fixedly connected to the outer wall of the discharge port of the feed bin 1 , and the fine particles conveyed by the spiral conveying roller 13 can be discharged through the discharge pipe 16 , which can prevent excessive accumulation of materials in the feed bin 1 .

[0032] A feed port is provided on the left inner wall of the feed bin 1, and a suction pipe 17 is fixedly connected to the surface of the suction fan 2. The end of the suction pipe 17 away from the suction fan 2 is fixedly connected to the dust hood 4. The dust generated in the feed bin 1 can be absorbed by the suction fan 2 through the suction pipe 17 and then enter the feed bin 1. At the same time, the waste of materials can be avoided, and the dust hood 4 can increase the absorption area.

[0033] In the utility model, when feeding fine granular materials, the suction fan 2 is first started, and the materials are put into the feeding port of the feeding bin 1. After the materials enter the feeding bin 1, dust is generated. The suction fan 2 sucks the dust into the dust collection cover 4 through the suction pipe 17, and then the motor 3 is started to drive the rotating rod 6 to rotate. The rotating rod 6 drives the top protrusion 7 to collide with the arc surface of the arc plate 10, so that the arc plate 10 drives the collision rod 9 to slide upward, and at the same time compresses the reset spring 11. When the protrusion 7 does not collide with the arc plate 10, , the reset spring 11 resets the arc plate 10 and contacts the protrusion 7 again, so that the collision rod 9 repeatedly collides with the filter screen 5 upward, causing the fine particles blocked on the surface of the filter screen 5 to collide and fall off, thereby preventing the filter screen 5 from being blocked when the suction fan 2 is vacuuming. At the same time, the filter screen 5 can avoid absorbing materials other than dust. At the same time, the rotating rod 6 drives the bevel gear 12 to rotate and mesh with the bevel gear 2 14, so that the bevel gear 2 14 drives the spiral conveying roller 13 to rotate to transport the material to the discharge pipe 16 in an orderly manner.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
