[0023] The utility model provides Figures 1 to 4 A dust prevention device for a batching bin is shown, comprising:

[0024] A batching bin body 1, a feeding frame 2 connected to the inside of the batching bin body 1 is fixedly provided on the top of the batching bin body 1;

[0025] A dust collection frame 3 is fixedly arranged at the outer end of the feeding frame 2. A plurality of dust collection holes 4 are opened at the top of the dust collection frame 3. The plurality of dust collection holes 4 are arranged in a circle on the outside of the feeding frame 2. A fixed dust collecting frame 5 is arranged at the top of the batching bin body 1. The bottom end of the fixed dust collecting frame 5 passes through the batching bin body 1 and extends to the inside of the batching bin body 1. The fixed dust collecting frame 5 is arranged on one side of the dust collection frame 3. A connecting pipe 6 is fixedly arranged between the dust collection frame 3 and the fixed dust collecting frame 5. The inside of the dust collection frame 3 and the inside of the fixed dust collecting frame 5 are connected through the connecting pipe 6. An exhaust cleaning mechanism is arranged inside the fixed dust collecting frame 5.

[0026] The exhaust cleaning mechanism includes an exhaust component and a cleaning component. The cleaning component includes a reciprocating screw rod 7 arranged inside the fixed dust collecting frame 5. The top end of the reciprocating screw rod 7 passes through the top end of the fixed dust collecting frame 5 and is rotatably connected to the top end of the fixed dust collecting frame 5 through a bearing. A motor 8 is fixedly arranged at the top of the fixed dust collecting frame 5. The output shaft of the motor 8 is fixedly connected to the top end of the reciprocating screw rod 7. The outer end of the reciprocating screw rod 7 is threadedly connected with a threaded sleeve 15. Four connecting rods 16 are fixedly arranged at the outer end of the threaded sleeve 15. A cleaning frame 17 is fixedly arranged at the outer end of the four connecting rods 16. The outer end of the cleaning frame 17 contacts the inner wall of the fixed dust collecting frame 5. The exhaust component includes a rotating rod 9 arranged inside the connecting pipe 6. A fan blade 10 is fixedly arranged at one end of the rotating rod 9. A first bevel gear 11 is fixedly arranged at the outer end of the reciprocating screw rod 7. The first bevel gear 11 is arranged at the top of the threaded sleeve 15. A second bevel gear 12 is fixedly arranged at the other end of the rotating rod 9. The second bevel gear 12 and the first bevel gear 11 are meshed with each other.

[0027] A first support plate 13 is fixedly provided at the bottom end of the inner wall of the fixed dust collecting frame 5, the bottom end of the reciprocating screw rod 7 passes through one end of the first support plate 13 and is rotatably connected to the first support plate 13 through a bearing, a second support plate 14 is fixedly provided at the bottom end of the inner wall of the connecting tube 6, one end of the rotating rod 9 passes through one end of the second support plate 14 and is rotatably connected to the second support plate 14 through a bearing.

[0028] When the external raw materials are added from the feeding frame 2 to the inside of the batching bin body 1, dust will be raised at the edge of the feeding frame 2. At this time, the motor 8 is started, and the output shaft of the motor 8 drives the reciprocating screw 7 to rotate, the reciprocating screw 7 drives the first bevel gear 11 to rotate, the first bevel gear 11 drives the second bevel gear 12 to rotate, the second bevel gear 12 drives the rotating rod 9 to rotate, the rotating rod 9 drives the multiple fan blades 10 to rotate, and the multiple rotating fan blades 10 will generate suction, and the external air will pass through the multiple dust suction holes 4 into the dust suction frame 3, and then enter the connecting pipe 6 and the fixed dust collecting frame 5. The raised dust will enter the dust suction frame 3, the connecting pipe 6 and the fixed dust collecting frame 5 together with the air, and the air carries the dust from the bottom end of the fixed dust collecting frame 5 into the batching bin body 1;

[0029] Since the threaded sleeve 15 is connected to the reciprocating screw 7 by threads, the threaded sleeve 15 moves up and down with the rotation of the reciprocating screw 7, and the threaded sleeve 15 drives multiple connecting rods 16 and a cleaning frame 17 to move up and down. The cleaning frame 17 will clean the raw materials adhered to the inner wall of the fixed dust collecting frame 5, and the cleaned raw materials will fall into the interior of the batching bin 1.

[0030] The utility model generates suction inside the dust collection frame 3 and the connecting pipe 6 through the exhaust component, so that the dust raised on the outside of the feeding frame 2 can be sucked into the connecting pipe 6 and the fixed dust collecting frame 5 in time, which effectively prevents the dust from escaping to the external environment, making the external working environment better and preventing the dust from affecting the equipment and the health of employees. The cleaning component can clean the raw materials adhered to the inside of the fixed dust collecting frame 5 and bring them into the batching bin body 1, preventing the collected raw materials from adhering to the inside of the fixed dust collecting frame 5. This embodiment specifically solves the problem in the prior art that when the resin powder raw material is added to the batching bin, the top of the batching bin is generally open for feeding. Since the resin raw material is a powdery raw material, a large amount of dust will be raised during the addition process, which will seriously pollute the working environment and affect the equipment, and the dust will also affect the health of the staff.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
