Description

Technical Field

[0001] The utility model relates to the technical field of dust-free feeding bins, in particular to a dust-free feeding bin. Background Art

[0002] The dust-free feeding silo uses manual labor to break the bag and pour the material into the feeding silo. According to the process requirements, it can be combined with a vibrating hopper or a stirring hopper for unloading, and is used for unloading operations of small bags of powdered materials.

[0003] For example, the dust-free feeding hopper with the function of preventing materials from getting stuck is authorized with announcement number CN217023747U. Although the above document can hinge a support plate on the upper side of the baffle to facilitate placing the material bag on the support plate, and then pull the material bag to lift one end of the support plate, thereby reducing the burden of the operator lifting the material bag to unload the material, but when the dust-free feeding hopper with the function of preventing materials from getting stuck in the above document is used, the vibration of the air hammer is used to discharge the material through the discharge pipe to realize the feeding function. However, since there is no material control device under the discharge pipe, it is impossible to control the discharge amount of the material and the speed at which the material falls during discharge, resulting in dust still being generated when the material falls, which is inconvenient to use. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] This embodiment:

[0019] See also Figure 1-4In this embodiment: a dust-free feeding bin includes a dust-free feeding bin 1, and outer shells 2 are fixedly connected on both sides of the outer wall of the dust-free feeding bin 1. A material control device 4 is provided at the lower part of the two outer shells 2. A feeding port 3 is opened on the left side of the top of the dust-free feeding bin 1, and the raw materials enter the dust-free feeding bin 1 through the feeding port 3. A discharge port 5 is opened at the lower part of the dust-free feeding bin 1, and the raw materials are discharged from the dust-free feeding bin 1 through the discharge port 5. A first dust reduction plate 6 is fixedly connected to the upper part of the dust-free feeding bin 1, and a second dust reduction plate 7 is fixedly connected to the middle of the dust-free feeding bin 1. The first dust reduction plate 6 and the second dust reduction plate 7 are used to reduce the falling speed of the raw materials, thereby reducing the dust production.

[0020] The material control device 4 includes an electric push rod 401, a rack 402, a spur gear 403, a connecting plate 404 and a baffle 405. The outer wall of the electric push rod 401 is fixedly connected to the shell 2. The model of the electric push rod 401 is selected according to actual use requirements to meet the working requirements. The output end of the electric push rod 401 is fixedly connected to the rack 402. The output end of the electric push rod 401 pushes the rack 402 to move up and down, and the outer wall of the rack 402 is meshed with the spur gear 403. When the rack 402 moves, the spur gear 403 rotates. The rear end of the spur gear 403 is rotatably connected to the shell 2 through a rotating shaft. The front end of the spur gear 403 is fixedly connected to a connecting plate 404. The spur gear 403 drives the connecting plate 404 to rotate. One end of the connecting plate 404 is fixedly connected to a baffle 405. The connecting plate 404 drives the baffle 405 to rotate. The top of the baffle 405 fits against the feeding port 3, and the baffle 405 is used to block the feeding port 3.

[0021] Adjust the electric push rod 401 so that the output end of the electric push rod 401 pushes the rack 402 to move upward, and the rack 402 causes the spur gear 403 to rotate downward. The spur gear 403 drives the connecting plate 404 to rotate, and the connecting plate 404 simultaneously drives the baffle 405 to rotate slowly. By adjusting the inclination angle of the baffle 405, the size of the discharge port 5 can be adjusted. At the same time, the inclination angle can be used to slow down the falling speed of the raw materials, reduce the generation of dust, and facilitate use.

[0022] A small fan 8 is fixed to the upper part of the interior of the two outer shells 2 through a bracket. The model of the small fan 8 is selected according to actual use requirements and can meet the work requirements. The input end of the small fan 8 is connected to the dust hood 9. The small fan 8 absorbs the dust generated inside through the dust hood 9. The output end of the small fan 8 is installed with a dust collecting bag 10. The dust collecting bag 10 is used to separate dust and air. The lower part of the outer wall of the outer shell 2 is fixed to the air hammer 11. The air hammer 11 is a prior art and will not be described in detail here. The output end of the air hammer 11 is in contact with the dust-free feeding bin 1. The air hammer 11 will vibrate after starting, thereby increasing the falling speed of the raw materials inside the dust-free feeding bin 1.

[0023] Working principle:

[0024] When the dust-free feeding bin is in use, first, the user pours the raw materials into the dust-free feeding bin 1 through the feed port 3. The raw materials will move in turn under the deceleration of the first dust reduction plate 6 and the second dust reduction plate 7, thereby reducing the output of dust. When the raw materials need to be discharged, the user adjusts the electric push rod 401 so that the output end of the electric push rod 401 pushes the rack 402 to move upward, and the rack 402 will cause the spur gear 403 to rotate downward, and the spur gear 403 drives the connecting plate 404 to rotate, and the connecting plate 404 simultaneously drives the baffle 405 to rotate slowly. By adjusting the inclination angle of the baffle 405, the size of the discharge port 5 can be adjusted. At the same time, the inclination angle can be used to slow down the falling speed of the raw materials, reduce the generation of dust, and facilitate use, thus completing the use of this device.

[0025] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
