[0034] like Figure 1-8 As shown: A specific implementation of a feed adjustment mechanism and a cleaning machine with the mechanism of the utility model:
[0035] Embodiment 1: Figure 2 , 4 -8, a feed adjustment mechanism is disclosed, including a supporting shell 12 and an inverted cone-shaped feed hopper 11, wherein the feed hopper 11 is mounted on the top of the supporting shell 12, and a feed port 13 is provided at the bottom of the feed hopper 11, and a feed flow plate 14 is provided on one side of the lower part of the feed port 13 to be tilted downward, and a plug-in card slot 15 is provided at the feed port 13 on the opposite side of the feed flow plate 14, and a feed adjustment plug-in card slot 15 is slidably provided with a feed adjustment plug-in card 16, and the feed adjustment plug-in card 16 is driven by a rack 17 and a gear 18 meshing with each other arranged at the lower part thereof, and the gear 18 is arranged on a feed adjustment shaft 19, and both ends of the feed adjustment shaft 19 are rotatably arranged on the side walls of the supporting shell 12, and the feed adjustment plug-in card 16 slides to control the opening and closing of the feed port 13.
[0036] That is, the utility model is provided with a feed flow plate 14 at the lower part of the feed port 13, which is used to change the direction of the material falling, slow down the falling speed, avoid the material from falling directly, and affect the air separation effect of the subsequent air separation process, so that the falling is more uniform; and the opening and closing size of the feed port 13 is controlled by moving the feed adjustment plug plate 16 forward and backward, and the feed adjustment plug plate 16 is driven by the gear 18 on the feed adjustment shaft 19 to realize linear control of the opening and closing size. The size of the feed port 13 can be fine-tuned to make the feeding of the material more uniform to meet the feeding needs of materials of different sizes.
[0037] Specifically, the rack 17 is arranged at the bottom of the feed adjustment plug plate 16, and the gear 18 is sleeved on the feed adjustment shaft 19. That is, the rack 17 is fixedly arranged with the feed adjustment plug plate 16, and the rack 17 can also be a square hole adapted to the gear 18, and the square holes are evenly arranged. The feed adjustment plug plate 16 can be composed of two parts, the front section is the plug plate part that matches the feed port 13, and the surface is smooth, and the rear section is the card plate that matches the plug plate slot 15, and the card plate is provided with a rack 17 or a square hole that matches the gear 18.
[0038] It should be noted that, in order to ensure that the gear 18 drives the rack 17 to run smoothly, there are two groups of meshing racks 17 and gears 18; two racks 17 are arranged in parallel at the bottom of the feed adjustment plug 16, and the two corresponding gears are coaxially arranged on the feed adjustment shaft 19. The two groups of racks 17 are symmetrically arranged on the feed adjustment plug 16, and the two gears 18 are also symmetrically arranged on the feed adjustment shaft 19. When the feed adjustment shaft 19 rotates, it can smoothly drive the feed adjustment plug 16 to move forward and backward, avoiding the feed adjustment plug 16 from tilting and getting stuck in the plug slot 15.
[0039] Furthermore, a limit plate 110 is provided at one end of the feed adjustment shaft 19, and the limit plate 110 is located on the inner wall of the support shell 12. A spring positioning plate 111 is provided at the opposite end of the limit plate 110 of the feed adjustment shaft 19, and the spring positioning plate 111 is located inside the support shell, and a compression spring 112 is provided between the spring positioning plate 111 and the inner wall of the support shell 12 at the far end of the limit plate 110.

[0040] That is, both ends of the feed adjustment shaft 19 are rotatably connected to the supporting outer wall, but the limit plate 110 and the clamping spring limit part of the freedom of the feed adjustment shaft 19. When the external force does not rotate the feed adjustment handle 113, the feed adjustment shaft 19 is fixed in the supporting shell 12. Relying on the restoring force of the clamping spring, the limit plate 110 is abutted against the supporting shell 12, avoiding the rotation of the feed adjustment shaft 19, making the opening and closing size state of the feed port 13 stable, and avoiding sudden changes of the feed port 13 during operation, resulting in uneven feeding.
[0041] In addition, if Figure 2-3 As shown, the utility model also provides a cleaning machine, including a frame 21, a wind selection component 22 installed on the top of the frame 21 and a screening component 23 installed at the bottom of the wind selection component 22, and the wind selection component 22 is provided with a feed adjustment mechanism as described in any of the above items.
[0042] That is, the above-mentioned feed regulating mechanism is applied to the cleaning machine. The cleaning machine has two processes: air selection and screening. The materials uniformly fed by the feed regulating mechanism complete the air selection operation under the action of the air selection component 22, and then directly enter the screening component 23 for screening. The cooperation between the feed regulating mechanism of the utility model and the air selection component 22 can meet the needs of cleaning materials of different sizes, and make the feeding of materials more uniform during air selection, and the cleaning effect is better.
[0043] It should be noted that the air selection component 22 includes an air selection channel 221 arranged at the lower part of the feed port 13, an air selection impeller 222 is installed on the feed flow plate 14 side of the air selection channel 221, the air selection impeller 222 is driven and connected to a wind selection motor, a light impeller outlet 223 is arranged on the opposite side of the air selection impeller 222, a secondary material outlet 224 is arranged at the lower part of the light impeller outlet 223, and an air selection material outlet 225 is arranged at the lower part of the air selection channel 221. The feed adjustment mechanism is installed in the middle position of the upper part of the air selection channel 221, so that the material entering the air selection channel 221 is blown out of impurities by wind under the rotation of the air selection impeller 222, and is discharged from the light impurity outlet 223 and the secondary material outlet 224 according to the weight of the impurities, and the air-selected material can fall directly. An air flow guide plate is arranged on the side wall of the air selection channel 221, so that the air flow blown out by the air selection impeller 222 is more stable and the air selection is more uniform.
[0044] Further, the screening component 23 includes a screening bracket 231, on which a large impurity screen plate 232, a small impurity screen plate and a small impurity flow plate are sequentially arranged from top to bottom, a large impurity outlet 233 is arranged at the lowest point of the large impurity screen plate 232, a clean material outlet 234 is arranged at the lowest side of the small impurity screen plate, and a small impurity outlet 235 is arranged at the lowest side of the small impurity flow plate. The screening bracket 231 is tiltedly arranged on the frame 21 through a connecting belt 236, and the screening bracket 231 is driven and connected to a screening motor 238 through an eccentric transmission connecting rod 237, and the screening motor 238 is fixedly mounted on the frame 21.
[0045] The materials after air selection directly fall onto the large impurities screen plate 232 of the screening component 23, and the screening motor 238 drives the eccentric transmission connecting rod 237 to vibrate the screening bracket 231, thereby vibrating the large impurities screen plate 232 and the small impurities screen plate, so that the materials entering the large impurities screen plate 232 are classified during the vibration process, and larger impurities remain on the large impurities screen plate 232 and are discharged from the large impurities outlet 233, and the materials enter the small impurities screen plate, and smaller impurities fall onto the small impurities flow plate below the small impurities screen plate and are discharged from the small impurities outlet 235, while the materials remain on the small impurities screen plate and are discharged from the clean material outlet 234.
[0046] The feed adjustment mechanism of the utility model changes the direction of the material through the feed flow plate 14, and can fine-tune the size of the feed port 13 through the horizontal feed adjustment plug plate 16, so that the material feeding is more uniform and can adapt to the feeding requirements of materials of different sizes. The cleaning machine of the utility model has the above-mentioned feed adjustment mechanism, which can accurately adjust the size of the material entering the air selection component 22 according to the actual material conditions, so that the air selection is more stable and the effect is better, and the material after air selection directly enters the screening component 23 to complete the screening process. The entire cleaning process is scientific, efficient and effective. Of course, the feed adjustment mechanism can also be used for other processing equipment, such as powdering machines, grinders, etc.
[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
