Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding equipment, in particular to a suction feeding machine. Background Art
[0002] Currently, commonly used particle feeding mechanisms include conveyor belts, screw feeders, and pneumatic feeders. Compared to conveyor belts and screw feeders, pneumatic feeders offer advantages such as smaller size, simpler structure, and relatively low noise. However, current pneumatic feeders can only deliver materials to the desired location and are unable to separate or air-select lighter materials from the conveyed material.
[0003] During grain production, the grain inevitably contains various lighter impurities, such as straw fragments in rice grains. To prevent these impurities from affecting processing, they must be separated during processing. The traditional method involves loading the grain into a sorting machine, using the sorting machine to separate the impurities, and then feeding the grain into a processing machine for processing. This process is complex and energy-inefficient. If a pneumatic loading mechanism could simultaneously load the grain and use its airflow to separate impurities from the grain, the grain processing process would be greatly simplified and energy-efficient.

[0007] One end of the feeding pipe is connected to the feeding port, the air inlet of the air extraction device is connected to the air extraction port, and the feeding port of the cyclone separator is connected to the air outlet of the air extraction device.
[0008] Furthermore, the feed port is arranged horizontally or inclined relative to the horizontal direction, and the air extraction port is arranged at the lower side of the feed port.

DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] like Figure 1 、 Figure 2As shown, the suction loading machine of the present invention includes a lifting bracket 1, a sealed storage bin 2, an exhaust device 3, a cyclone separator 4, and a feeding pipe 5. The exhaust device 3 can be various vacuum pumps, air extraction pumps, etc. The sealed storage bin 2 is mounted on the lifting bracket 1. A discharge port 21 is provided at the bottom of the sealed storage bin 2. A removable discharge mechanism 7 is mounted on the sealed storage bin 2 to control the opening and closing of the discharge port 21. The sealed storage bin 2 is also provided with a feed port 22 and an exhaust port 23 located above the discharge port 21. The exhaust port 23 is located below the feed port 22 to simultaneously extract air and separate material that falls from the feed port 22. One end of the feeding pipe 5 is connected to the feed port 22. The air inlet of the exhaust device 3 is connected to the exhaust port 23. The feed port of the cyclone separator 4 is connected to the air outlet of the exhaust device 3.
[0021] When the suction feeder of the present invention is loading, the discharge mechanism 7 is first closed to the discharge port 21, and then the suction device 3 is activated. The suction device 3 extracts the air in the sealed storage bin 2 through the suction port 23, creating a negative pressure in the sealed storage bin 2. One end of the feeding pipe 5 is inserted into the material to be loaded, and the material is lifted into the sealed storage bin 2 by the air flow under the pressure of the external air. After entering the sealed storage bin 2, the material falls under the action of gravity and accumulates at the bottom of the sealed storage bin 2. As the material falls, the airflow generated by the suction port 23 below the feed port 22 air-selects the falling material, allowing the lighter material to flow out of the suction port 23 with the air flow, thereby achieving air-selection of the loaded material. The loading and sorting are completed in one go, greatly simplifying the grain processing process and saving energy. The impurities separated by air finally enter the cyclone separator 4, which performs gas-solid separation. When the material in the sealed storage bin 2 reaches a certain amount and needs to be unloaded, the unloading mechanism 7 is opened to unload the material into the hopper of the processing equipment.
[0022] It is understood that the distance between the air extraction port 23 and the feed port 22 cannot be too close or too far. If it is too close, the falling material will be extracted, while if it is too far, the falling material cannot be air-selected. Therefore, it is necessary to reasonably set the position of the air extraction port 23. The specific setting position of the air extraction port 23 can be determined through experimental methods based on relevant factors such as the type of actual feed material and the rated displacement of the air extraction device 3.
[0023] The orientation of the feed port 22 determines the direction in which the material and airflow enter the sealed storage bin 2. The orientation of the feed port 22 can be set horizontally or tilted relative to the horizontal direction. The orientation of the feed port 22 can be tilted upward or downward relative to the horizontal direction. Of course, in some embodiments, the orientation of the feed port 22 is also set vertically downward. In the embodiment of the present invention, the orientation of the feed port 22 is set horizontally or tilted relative to the horizontal direction. When the orientation of the feed port 22 is set horizontally or tilted relative to the horizontal direction, the air exhaust port 23 can be set directly below the feed port 22, directly below in front, or below to the side. Figure 2 and Figure 3 As shown, when the feed port 22 is set horizontally or tilted relative to the horizontal direction, in the present invention, preferably, the air extraction port 23 is set at the lower front side of the feed port 22. Experiments have shown that when the feed port 22 is set horizontally or tilted relative to the horizontal direction, the air extraction port 23 is set at the lower front side of the feed port 22, and the air extraction port 23 has the best air separation effect on the material.
[0024] In order to better air-select the fallen materials, Figure 2 As shown, the feed inlet 22 is further provided with a vertical deflector 24 on the side thereof for guiding the airflow flowing from the feed inlet 22 toward the bottom of the sealed storage bin 2. The lower end of the vertical deflector 24 is provided with a transverse deflector 25 extending toward the air extraction port 23 to direct the airflow toward the air extraction port 23. The transverse deflector 25 generally extends to connect with the side panels of the sealed storage bin 2. This structure allows the airflow 6 entering from the feed inlet 22 to flow downward first and then laterally toward the air extraction port 23. This makes it easier for the airflow 6 to lift impurities on the surface of the material 8 in the sealed storage bin 2, allowing them to flow out of the air extraction port 23 with the airflow, further improving the air separation efficiency of the loader. The air extraction port 23 can be located on the side panels of the sealed storage bin 2 or on the transverse deflector 25. In the present invention, the air extraction port 23 is preferably located on the transverse deflector 25 and faces downward. The air extraction port 23 is provided on the transverse guide plate 25 and is arranged downward, which is not only convenient for installation of the air extraction device but also most beneficial for air separation of the material.
[0025] The lifting bracket 1 can be welded from profiles, and its height can be set to an adjustable or non-adjustable structure. In order to facilitate the adjustment of the loading height of the loading machine according to actual conditions, such as Figure 4As shown, the lifting bracket 1 is configured as a height-adjustable structure, comprising a lower bracket 11 and an upper bracket 12. The upper bracket 12 is vertically slidably connected to the lower bracket 11. The lower bracket 11 is provided with a locking member 13 for locking the upper bracket 12 in position. The sealed storage bin 2 is mounted on the upper bracket 12. In this way, the upper bracket 12 can be slid upward or downward as needed to adjust the height of the sealed storage bin 2, and thus the loading height of the loader. The locking member 13 can be a screw, bolt, latch, etc.
[0026] The unloading mechanism 7 can adopt an existing heavy hammer type flap lock air valve to realize automatic opening and closing of unloading. In some embodiments, the unloading mechanism 7 can also adopt a manually controlled or automatically controlled plug-in plate structure or a rotating flap structure arranged at the unloading port 21. Figure 2 In the embodiment, the unloading mechanism 7 includes a flap disposed at the unloading port 21 for controlling the opening and closing of the unloading port 21. One end of the flap is hingedly connected to the sealed storage bin 2. When unloading is required, the flap is rotated to open the unloading port 21. In the embodiment of the utility model, the opening and closing of the flap are controlled by the start and stop of the suction device 3. The specific control principle is as follows: the flap is positioned appropriately so that it can be closed by the suction of the suction device 3. The feeding pipe 5 is first inserted into the material to reduce the amount of airflow entering the sealed storage bin 2 from the feeding pipe 5, so that the airflow enters mainly from the unloading port 21. The suction device 3 is then activated, and the negative pressure (suction) generated by the suction device 3 causes the flap to rotate and close the unloading port 21. When unloading is required, the suction device 3 is stopped, and the flap automatically opens under the action of gravity to unload. During the operation of the feeder, the start and stop of the suction device 3 are automatically controlled by a controller.
