Description

Technical Field

[0001] This utility model specifically relates to the field of feeding machine technology, and more specifically to a dust-free feeding machine. Background Technology

[0002] Dust-free feeding machines are used to reduce dust emissions and ensure that the working environment is not polluted when feeding powdered materials. At the same time, when adding materials, they can break up the clumps in the materials to prevent them from clogging the feeding structure during transmission. When traditional feeding machines add materials, a large amount of material rushes into the hopper at the same time. This causes a large amount of material to be pushed in the feeding port, affecting the feeding efficiency. In addition, the material may generate a large amount of floating dust when it is poured in. A large amount of dust will affect the surrounding environment and may cause certain harm if inhaled by the human body. A search revealed that Chinese patent application CN202422211697.9 discloses a dust-free feeding machine; it includes a feeding and screening device and a feeding device, wherein the feeding device is mounted on the feeding and screening device; the feeding and screening device includes a screening shell, a feeding hopper, a left slide, a right slide, a screen ring frame, a circular screen disc, a bearing, an arc-shaped rack, a rack, a motor, a crankshaft, a screening pull rod, an auxiliary gear, and two screening hinge rods; the feeding hopper is located at the bottom of the screening shell; the crankshaft is movably connected to the screening shell and one end is connected to the motor; the motor is mounted on the screening shell; the left and right slides are connected to both sides of the screen ring frame and are slidably connected inside the screening shell; In the aforementioned patent, although an L-shaped lifting rod is installed inside the feeding device to achieve the material transmission effect when adding materials, the material that is clumped inside cannot be effectively broken up during the transmission process and will still be added to the hopper in a clumped manner. As a result, the clumped material will cause feeding blockage during feeding, affecting the feeding effect. Utility Model Content

[0003] The purpose of this invention is to provide a dust-free feeding machine. In this device, materials are added to a screen plate inside the hopper. The screen plate effectively separates lumpy materials. During the material's descent, the screen holes on the screen plate also block the lumpy materials, achieving a crushing effect. After screening, the powder and lumpy powder are effectively separated. The powder falling below the screen plate is effectively conveyed by auger rollers installed inside the conveyor frame. When the material passes through the screen plate, the dust generated is effectively extracted by a negative pressure fan at the top of the housing, preventing a large amount of dust from floating inside the housing. This solves the problems mentioned in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A dust-free feeding machine includes a frame; a bracket is fixedly installed inside the frame; a hopper is fixedly installed inside the bracket; a screen plate is fixedly installed inside the hopper; the screen plate is inclined; and the bottom of the hopper is open. A box is fixedly installed at one end of the top of the hopper; an observation door is movably installed on the inclined surface of the box; the bottom ends of the observation door are movably installed with a rotating shaft; the two ends of the rotating shaft extend to both sides of the box and are movably installed with an electric push cylinder through a fisheye joint; the end of the electric push cylinder away from the rotating shaft is connected to the top of the frame with a Rongguang connecting frame.

[0005] As a further technical solution of this utility model, a rectangular groove is provided on the top of the box, which cooperates with the feed inlet of the negative pressure fan; the negative pressure fan is fixedly installed on the top of the box.

[0006] As a further technical solution of this utility model, the opening at the bottom of the box body matches the opening groove on the side wall of the transmission frame; the transmission frame is fixedly installed with the hopper through a sealing plate.

[0007] As a further technical solution of this utility model, the transmission frame is inclined; the side wall of the transmission frame is movably connected to one end of the frame body with a connecting plate.

[0008] As a further technical solution of this utility model, a auger roller is movably installed inside the transmission frame; one end of the auger roller is fixedly installed with a drive motor; the drive motor is fixedly installed at the end of the transmission frame away from the hopper.

[0009] Compared with the prior art, the beneficial effects of this utility model are: In use, the electric push cylinders installed on both sides of the box drive the rotating shaft to open the observation door between the box and the box, which facilitates the addition of materials. When the materials are added to the screen plate inside the hopper, the powder is effectively transferred to the bottom of the hopper through the screen holes on the screen plate. The lumpy materials are crushed during the rolling process, thereby reducing material waste. In this invention, lumpy materials that are not completely broken up accumulate at the connection between the bottom of the screen plate and the inner wall of the hopper, which avoids the lumpy materials from causing blockages in the conveying device during feeding. The inside of the box is connected to the inside of the negative pressure fan. When materials are added, the dust generated is effectively extracted by the negative pressure fan installed on the top of the box, thereby achieving separate storage of the dust. In this invention, the opening at the bottom of the hopper matches the opening groove on the side wall of the conveyor frame. The opening groove of the conveyor frame is fixedly installed with the bracket and the hopper by a sealing plate to prevent material leakage. In this invention, during material feeding and conveying, a drive motor installed on the top of the conveyor frame drives the rotation of the auger roller, thereby transferring the material inside the hopper to the processing device through the discharge port on the conveyor frame, achieving the effect of automatic dust-free feeding.
