[0018] To make the purpose, technical solutions and advantages of the present invention clearer, reference will now be made to Figure 1 、 Figure 2The present invention is further described in detail with examples so that the public can better understand the implementation method of the present invention. The specific implementation method of the present invention is as follows:

[0019] A composite impurity cleaning machine includes a frame 1, on which are provided an electric fan 2, a three-way pipe 3, a wind hoist 4, a conveying pipe 5, a specific gravity hose 6 and a specific gravity stone remover 7. The air inlet of the electric fan 2 is connected to the three-way pipe 3, the upper end of the wind hoist 4 is connected to the three-way pipe 3, the three-way pipe 3 is connected to the specific gravity stone remover 7 through the specific gravity hose 6, the wind hoist 4 is connected to the specific gravity stone remover 7 through the conveying pipe 5, a grain leveling mechanism 8 is rotatably arranged in the conveying pipe 5, and a demagnetization mechanism 9 is arranged in the pipe wall at the lower part of the grain leveling mechanism 8. The electric fan 2 utilizes the three-way pipe 3 to realize the coordinated movement of the wind hoist 4 and the specific gravity stone remover 7 to realize their respective functions, from lifting grains, cleaning dust and large and small impurities, to demagnetization, to removing side stones, which can be completed at one time. The machine has a compact structure, small footprint, low energy consumption, reliable performance and easy operation.

[0020] The wind hoist 4 includes a lifting pipe 41 and a volume chamber 42. The lifting pipe 41 extends into the lower part of the volume chamber 42. A material blocking inclined plate A10, a material blocking inclined plate B11 and a plurality of material blocking inclined plates C12 are provided in the volume chamber 42. The material blocking inclined plates A10 and the material blocking inclined plates B11 are staggered one above and one below. In this embodiment, there are three material blocking inclined plates C12. The material blocking inclined plates C12 are arranged above the material blocking inclined plates B11. The three material blocking inclined plates C12 are evenly distributed on both sides with the central axis of the volume chamber 42 as the axis. The three material blocking plates are arranged upward in the order of one left and one right, and the projections intersect with the central axis of the volume chamber 42. ; The lower part of the volume chamber 42 is provided with an inclined flow plate 15 for quickly allowing the grain to enter the conveying pipe 5; a number of strip holes are evenly arranged on the baffle ramp C12, which can pass small debris such as wheat awns; different baffle ramps are provided in the volume chamber 42, which can not only prevent the grain from being sucked out by the electric fan 2 when lifting and causing food waste, but also form a cyclone in the cavity between the baffles, so that large debris and dust with smaller specific gravity are sucked out and collected by the electric fan 2, which can not only achieve the purpose of lifting grain, but also prevent grain from being sucked out and causing waste, and can also achieve the purpose of cleaning large and small debris. It has complete functions and high cost performance.

[0021] The lower end of the lifting pipe 41 is connected to the storage bin, and a wind regulating mechanism is provided at the entrance of the lifting pipe 41. The upper end is connected to a gradual channel 13. The outlet of the gradual channel 13 is provided on the upper part of the baffle inclined plate A10. The outlet cross-section of the gradual channel 13 is rectangular. Through the setting of the gradual channel 13, the grains can be directly lifted to the top of the baffle inclined plate A10. The lifted grains mixed with impurities are scattered on the baffle inclined plate A10, which is conducive to the large and small impurities being sucked out and collected by the electric fan 2. The grains flow to the inclined flow plate 15 at the bottom of the volume chamber 42, and then enter the conveying pipe 5.

[0022] The delivery pipe 5 includes a delivery pipe A51 and a delivery pipe B52. One end of the delivery pipe A51 is connected to the volume chamber 42, and the other end extends into the delivery pipe B52. The other end of the delivery pipe B52 extends into the specific gravity stone remover 7.

[0023] A pressure flap valve is provided at one end of the delivery pipe A51 extending into the delivery pipe B52.

[0024] A grain leveling mechanism 8 and a demagnetizing mechanism 9 are provided in the conveying pipe B52. The grain leveling mechanism 8 includes a support shaft and an impeller. The support shaft is fixedly connected to the conveying pipe B52, and the impeller is rotatably provided on the support shaft. The impeller rotates due to the flow of grains, so that the grains pass through evenly; the demagnetizing mechanism 9 includes a magnetic box and a permanent magnet. The permanent magnet is placed in the magnetic box, and the magnetic box is communicated with the conveying pipe B52. When the grains pass through evenly, it is more conducive to the permanent magnet to absorb the iron in the grains.

[0025] The specific gravity hose 6 includes a connecting pipe 61 , a regulating chamber 62 and a bag tube 63 . The connecting pipe 61 is connected to the bag tube 63 through the regulating chamber 62 . The flexibility of the bag tube 63 can remove the vibration of the specific gravity stoner 7 .

[0026] An adjusting plate 14 is rotatably provided on the central axis of the adjusting chamber 62 , which can adjust the suction volume in the specific gravity stone removing machine 7 .

[0027] The working principle and working process of the present invention are as follows: when the equipment is started, the air in the volume chamber 42 and the conveying pipe A51 is discharged through the rotation of the impeller in the electric fan 2. At this time, the pressure flap is closed, and the gas pressure in the wind hoist 4 is lower than the outside atmospheric pressure, forming an air pressure difference. Under the action of the pressure difference, the raw grains are lifted to the upper part of the baffle ramp A10 in the storage bin through the lifting pipe 41 and the gradual channel 13, and are evenly dispersed on both sides of the discharge port of the gradual channel 13. The lighter-grained impurities and dust are sucked out and collected by the electric fan 2; when the internal negative pressure is adjusted, when the negative pressure increases, part of the grains are sucked into the upper part of the baffle ramp B11, and part is blocked by the baffle ramp C12 to prevent the grains from being discharged. Part of the wheat awns enter the wind hoist 4 through the strip holes evenly arranged on the baffle ramp C12 and are discharged, thereby completing the purpose of removing impurities and dust.

[0028] After the raw grains from which large and small impurities and dust are removed accumulate to a certain extent, they flow to the inclined flow plate 15 and then reach the conveying pipe A51. When the grain reaches a certain amount, pressure is generated. When the pressure is greater than the pressure of the pressure flap door, the pressure flap door is pushed open and the raw grains are sent to the end of the conveying pipe B52. Due to the weight of the raw grains and the inclination of the conveying pipe B52, it slides down along the pipeline, thereby driving the impeller of the grain leveling mechanism 8 to rotate, and the raw grains are evenly dispersed. The magnetic materials are collected by the permanent magnet of the demagnetization mechanism 9, and the permanent magnets are taken out and cleaned regularly in the magnetic box, thereby achieving the purpose of removing magnetic materials.

[0029] The grains containing shoulder stones continue to be transported along the retaining inclined plate B11 to the specific gravity stoner 7 for stone removal. The specific gravity stoner 7 is connected to the tee pipe 3 through the specific gravity hose 6. The grains and shoulder stones are affected by wind. According to the difference in specific gravity and suspension speed between the grains and shoulder stones, the porosity between the particles is increased due to the vibration of the screen surface and the action of the air flow passing through the material layer. The material is in a fluidized state, which promotes automatic grading. The stones and the like with higher specific gravity sink to the bottom layer and contact the screen surface, and the grains with lower specific gravity float to the upper layer. Under the push of gravity, inertia and continuous feeding, the grains are separated from the shoulder stones, completing the cleaning work.
