Description

Technical Field

[0001] This utility model relates to the field of air separator technology, specifically a rapeseed impurity separation fan. Background Technology

[0002] The working principle of a small air separator is based on aerodynamic classification, which uses high-speed airflow to classify materials. Its core lies in using the difference in suspension velocity of different materials in the airflow to achieve separation. An internal fan generates a controllable airflow (positive or negative pressure). After the materials enter, lighter materials (such as plastics and paper scraps) are carried to the top of the separator due to their faster suspension velocity, while heavier materials (such as bricks and metals) settle along a specific path due to gravity. By reducing the number of fan blades or adjusting the height of the separator's hood, the airflow intensity and classification accuracy can be changed to adapt to different material requirements.

[0003] Patent CN220574045U discloses a tea air separator for separating impurities. During operation, tea leaves are stored in a hopper, and then an electromagnetic vibrating feeding assembly is activated. Under the action of the electromagnetic vibrating feeding assembly, the tea leaves entering the inlet are evenly and dispersed. The blowing mechanism blows lighter impurities towards the discharge outlet, while the tea leaves themselves fall directly to the outlet, achieving separation and impurity removal. This tea air separator allows for even feeding of tea leaves, resulting in more thorough screening and significantly improved work efficiency.

[0004] The shortcomings of the above solution are: when rapeseed is fed into the air separator, it is easy to accumulate and affect the air separation effect. Some impurities and dust are trapped inside the rapeseed, and thus cannot be separated smoothly by air separation. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a rapeseed impurity separation blower to solve the problems mentioned in the background art. This utility model has a novel structure. The drive component shakes and separates the rapeseed sent out by the feed frame, thereby preventing the rapeseed from accumulating together. The cleaning component cleans the bottom of the blower box and pushes out the rapeseed that falls outside the discharge port, thus preventing the raw material from being unable to be sent out.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapeseed impurity separation blower, comprising a wind box, a blower fixedly installed at one end of the wind box, a dust outlet at the other end of the wind box, a feed frame fixedly installed at the top of the wind box, a discharge outlet at the bottom of the wind box, a collection box at the bottom of the discharge outlet, a driving assembly on the outside of the feed frame, the driving assembly including a perforated plate slidably installed inside the feed frame, a cleaning assembly inside the wind box including a third scraper, the third scraper sliding along the side of the discharge outlet towards the dust outlet, a second scraper slidably installed on the other side of the wind box at the discharge outlet, a dustproof net fixed at the connection end between the wind box and the wind box, and a first scraper slidably installed on the outer surface of the dustproof net, the first scraper and the second scraper being drively connected.

[0007] Furthermore, the drive assembly also includes a fence, with the feed frame fixed to the top of the perforated plate, and the perforated plate sliding along the bottom of the fence.

[0008] Furthermore, the feed frame has a moving groove on one side parallel to the perforated plate, and a first toothed plate is fixed through the moving groove of the perforated plate. A first gear is meshed with the bottom of the first toothed plate. A drive motor is fixed on the outer wall of the feed frame at the position corresponding to the first gear, and the output end of the drive motor is fixedly connected to the first gear.

[0009] Furthermore, the cleaning assembly also includes a first connecting rod, with the first connecting rod fixed to the outer side of the third scraper extending out of the air box. A second toothed plate is fixed to the top of the first connecting rod, and a second gear is meshed with the bottom of the second toothed plate. The second gear is rotatably mounted on the outer wall of the air box.

[0010] Furthermore, a transmission belt is installed on the outer side of the first gear, and the pulley on the other side of the transmission belt is fixedly connected to the second gear.

[0011] Furthermore, the bottom of the first gear is meshed with a third gear, the side plate of the third gear is meshed with a third toothed plate, the bottom of the third toothed plate is fixed with a connecting frame, the bottom of the first scraper is fixed with a second connecting rod, the bottom of the second connecting rod slides through the bellows and is fixedly connected to the connecting frame, the bellows is fixed with a limit frame corresponding to the side plate of the third toothed plate, and the third toothed plate slides along the inside of the limit frame.

[0012] Furthermore, push rods are rotatably connected to both sides of the first scraper via a rotating shaft, and the other end of the push rod is rotatably connected to the second scraper via a rotating shaft.

[0013] Furthermore, two top rods are fixed to the bottom of the first scraper, and a baffle is rotatably mounted on the wind box opposite the bottom of the first scraper via a rotating shaft and a torsion spring.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a drive motor to drive the first gear to rotate. The first gear meshes with the first toothed plate, causing the perforated plate to slide back and forth along the bottom of the moving groove and the fence, thereby accelerating the separation and shaking of rapeseed on the perforated plate. When it falls into the bellows, it can reduce the accumulation of rapeseed.

[0016] 2. This utility model utilizes the meshing of a first gear and a third gear, and the meshing of a third toothed plate with the third gear, to allow the third toothed plate to slide downwards along the limiting frame. A connecting frame pulls the second connecting rod and the first scraper along the surface of the dustproof net. When the first scraper reaches its lowest point, the push rod presses against the baffle, opening it and clearing the dust accumulated on the dustproof net from the bottom of the airbox. Simultaneously, the second scraper, connected by a push rod, slides along the bottom of the airbox, pushing the dust on one side of the bottom of the airbox towards the discharge port. Through the transmission belt, the second gear rotates and meshes with the second toothed plate, which in turn moves the first connecting rod. The third scraper moves along the other side of the discharge port, clearing away the rapeseed that has fallen to the sides of the discharge port at the bottom of the airbox.

[0017] 3. Compared with the prior art, this utility model uses a drive component to shake and separate the rapeseed sent out by the feeding frame, thereby preventing the rapeseed from piling up. The cleaning component cleans the bottom of the bellows and pushes out the rapeseed that falls outside the discharge port, thus preventing the raw material from being unable to be sent out.
