Description

Technical Field

[0001] This utility model relates to the field of air screen cleaning machine technology, specifically to a feeding mechanism for an air screen cleaning machine. Background Technology

[0002] An air-screen cleaner is a material processing device that combines air separation and screening. It is mainly used to remove impurities from materials, improving their cleanliness and purity. Its working principle involves air separation based on aerodynamic characteristics, while simultaneously screening based on the size characteristics of the materials, thus achieving fine processing. In the production of milk thistle extract, an air-screen cleaner is needed to process milk thistle (seeds).

[0003] A search revealed that utility model patent CN218902697U discloses a wind-screen cleaning machine with a feeding mechanism. This wind-screen cleaning machine includes a machine body, a rotating mechanism, and a striking mechanism. The machine body has a conveying channel. Through the coordinated use of the machine body, conveying channel, funnel, motor, rotating rod, bevel gear, fixed plate, rotating shaft, rotating plate, transmission rod, first gear, second gear, rotating disk, and rubber ball, the machine performs wind-screen cleaning of seeds. Compared to traditional wind-screen cleaning machines, this machine can control the seed feeding speed and quantity during use, ensuring effective wind-screen cleaning and preventing seed accumulation in the funnel, thus guaranteeing uniformity of seed cleaning. This also increases the practicality of the device, facilitating its promotion and use.

[0004] However, the aforementioned patents still have the following shortcomings: the discharge port position of the fixed plate in the conveying channel is fixed, making it inconvenient to disperse the material into the air screen cleaner, which will also affect the screening quality and efficiency of the air screen cleaner; and the funnel is generally placed at a high position, making it inconvenient to add the material into the funnel. To address this, we propose a feeding mechanism for an air screen cleaner. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a feeding mechanism for an air-screen cleaning machine.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A feeding mechanism for an air-screen cleaning machine includes an air-screen cleaning machine, a lifting mechanism on the side of the air-screen cleaning machine, a material distribution pipe fixedly sleeved on the top of the air-screen cleaning machine, a material distribution net fixedly sleeved at the bottom of the inner cavity of the material distribution pipe, a funnel fixedly connected to the top of the material distribution pipe, a mounting frame fixedly connected to the top of the funnel, a second motor fixedly mounted on the top surface of the mounting frame, the output shaft of the second motor extending into the inner cavity of the funnel and fixedly connected to a transmission rod, a second spiral conveying rod fixedly connected to the bottom end of the transmission rod, the bottom end of the second spiral conveying rod movably sleeved into the inner cavity of the material distribution pipe, a scraper fixedly connected to the bottom end of the rotating shaft of the second spiral conveying rod, and the bottom end of the scraper abutting against the top surface of the material distribution net.

[0008] As a preferred embodiment of this utility model, the lifting mechanism includes a lifting cylinder fixedly connected to the side of the air-screen cleaning machine, a discharge hopper fixedly connected to the side of the bottom end of the lifting cylinder, a feeding pipe fixedly connected to the side of the top end of the lifting cylinder, the end of the feeding pipe extending to the upper part of the inner cavity of the funnel, a first spiral conveying rod rotatably connected to the inner cavity of the lifting cylinder, and a first motor fixedly installed at the top end of the lifting cylinder, the output shaft of the first motor being connected to the top end of the rotating shaft of the first spiral conveying rod.

[0009] As a preferred embodiment of this utility model, a plurality of stirring plates are fixedly connected to the side of the transmission rod and located in the inner cavity of the funnel.

[0010] As a preferred embodiment of this utility model, a control panel is provided on the outside of the air-screen cleaning machine.

[0011] In a preferred embodiment of this utility model, the side of the second spiral conveyor rod is in contact with the inner wall of the feeding tube.

[0012] In a preferred embodiment of this utility model, the side of the first spiral conveyor rod is in contact with the inner wall of the lifting cylinder.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, when the material is added into the funnel, the second motor drives the stirring plate, the second spiral conveying rod and the scraper to rotate. The stirring plate is used to prevent the material in the inner cavity of the funnel from being blocked. The second spiral conveying rod is used to guide the material in the inner cavity of the funnel into the inner cavity of the feeding pipe. The feeding net at the bottom of the inner cavity of the feeding pipe disperses the material and feeds it into the air screen cleaner. The scraper is used to scrape the material above the feeding net to prevent the feeding net from being blocked. This realizes the function of dispersing the material into the air screen cleaner for air screen cleaning.

[0015] (2) In this utility model, by using the lifting cylinder, the discharge hopper, the injection pipe, the first spiral conveying rod and the first motor in combination, the material is put into the discharge hopper before the air screen is cleaned, so that the material falls from the bottom of the discharge hopper into the lifting cylinder. The first motor drives the first spiral conveying rod to rotate, and the rotation of the first spiral conveying rod drives the material at the bottom of the lifting cylinder to move upward. When the material is lifted by the first spiral conveying rod to the side of the injection pipe, the material in the lifting cylinder is guided into the inner cavity of the funnel along the injection pipe, thus realizing the function of automatically lifting the material at the lower position to the funnel at the higher position.

A discharge hopper 13 is fixedly connected to the side of the bottom end of the lifting cylinder 12. A feeding pipe 14 is fixedly connected to the side of the top end of the lifting cylinder 12. The end of the feeding pipe 14 extends to the top of the inner cavity of the funnel 4. A first spiral conveying rod 15 is rotatably connected to the inner cavity of the lifting cylinder 12. A first motor 16 is fixedly installed at the top end of the lifting cylinder 12.

[0035] Working principle: In use, firstly, the material to be screened by the air filter is placed into the inner cavity of the discharge hopper 13, allowing the material to fall from the bottom of the discharge hopper 13 into the lifting cylinder 12. Then, the first motor 16 is started to drive the first spiral conveyor rod 15 to rotate. The rotation of the first spiral conveyor rod 15 causes the material at the bottom of the lifting cylinder 12 to move upward. When the material is lifted by the first spiral conveyor rod 15 to the side of the injection pipe 14, the material in the lifting cylinder 12 is guided into the inner cavity of the funnel 4 through the injection pipe 14.
