The arc-shaped bottom plate is the first barrier for corn when it falls, so that the corn kernels cannot fall directly, and the time for the corn kernels to be blown by the blower is increased.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. Since a lot of dust and small stones will adhere to the bottom of the corn kernels during the drying process, a large amount of dust will cause harm to the health of the workers. Therefore, the present invention sets a dust removal mechanism, increases the contact area between the corn kernels and the air, and prolongs the falling time of the corn kernels, so that the dust on the surface of the corn kernels is continuously blown into the dust reduction chamber by the blower, thereby improving the dust suction effect, and the stones contained in the corn kernels are graded, removed and collected, thereby reducing the impurity content of the corn kernels.

[0019] 2. In the process of dust removal by wind, some corn kernels will be blown away by the wind, which makes recovery difficult and increases the burden on the staff. The present invention sets a recovery mechanism to recover and clean the corn kernels, while reducing dust scattering, making the work of the staff not only simple to operate and environmentally friendly, but also reducing food waste.

[0020] 3. The existing dust removal equipment only performs wind dust removal on the corn kernels entering the equipment. The speed at which the corn kernels pass through the fan is too fast, resulting in a short time for the wind to blow the dust, resulting in poor dust removal effect. The present invention controls the feeding speed of the corn kernels by arranging a feeding component and a buffer component to avoid accumulation and prevent the corn kernels from blocking the grain suction pipe when feeding, thereby increasing the dispersibility of the corn kernels so that the dust adhered to the surface can increase the area in contact with the air and prevent the corn kernels from falling directly. The time that the corn kernels are in the dust blown by the blower is increased, and the rubber disk is knocked and vibrated so that the corn kernels are subjected to the elastic rebound of the rubber disk, thereby strengthening the mutual friction between the surfaces of the corn kernels, causing the dust to separate from the surface of the corn kernels and improving the dust removal efficiency.

[0021] 4. The existing dust removal equipment cannot remove the stones mixed in the corn kernels at the same time during the wind dust removal process. The presence of stones will also affect the quality and appearance of the corn kernels. The present invention sets a separation component to separate the smaller stones from the corn kernels by filtering, and separates the larger stones from the corn kernels by centrifugal force, and cleans and collects the stones in the corn kernels by classification, thereby reducing the content of solid debris in the corn kernels.

[0037] The impurity removal mechanism 4 includes an inclined plate 402, the outer wall of the inclined plate 402 is fixedly connected to the inner wall of the processing chamber 8, the top of the inclined plate 402 is fixedly connected to a vibrator 403, the top of the vibrator 403 is fixedly connected to a round shell 404, the inner wall of the round shell 404 is fixedly connected to a separation component 405, the top of the separation component 405 is rotatably connected to a buffer component 406, the top of the buffer component 406 is fixedly connected to a telescopic rod 407, the top of the telescopic rod 407 is fixedly connected to a feed component 409, and the bottom of the feed component 409 is fixedly connected to the outer wall of the separation component 405;

[0038] A recovery mechanism 5, the outer wall of the recovery mechanism 5 is slidably connected to the inner wall of the body 1;

[0039] The recovery mechanism 5 comprises a sealing shell 503 , the outer wall of the sealing shell 503 is slidably connected to the inner wall of the body 1 , the inner wall of the sealing shell 503 is fixedly connected to a filter plate 504 , and the top of the filter plate 504 is fixedly connected to a cleaning assembly 506 .

[0040] A blower 3 is fixedly connected to the outer wall of the machine body 1 on the side close to the grain suction pipe 2, a grain outlet pipe 7 is fixedly connected to the outer wall of the machine body 1 on the side close to the blower 3, a glove box 6 is fixedly connected to the top of the grain outlet pipe 7, and the outer wall of the glove box 6 is fixedly connected to the outer surface of the machine body 1.

[0041] During operation, the corn kernels spread on the ground are sucked into the body 1 through the grain suction pipe 2 by an external induced draft fan, and the blower 3 is turned on at the same time. The corn kernels entering the processing chamber 8 first contact the feeding assembly 409, and the feeding assembly 409 separates the accumulated corn kernels through the telescopic rod 407, so that they are dispersed into the processing chamber 8, so as to increase the contact area between the corn kernels and the air, so that the dust attached to the corn kernels is blown into the dust reduction chamber 9 by the blower 3, and the corn kernels coming out of the feeding assembly 409 fall onto the buffer assembly 406, and the feeding speed of the corn kernels is controlled by the buffer assembly 406, so that the working intensity of the separation assembly 405 is kept moderate, and finally the separation assembly 405 throws the corn kernels out by centrifugal force, so that they fall onto the inclined plate 402 and are discharged from the grain outlet pipe 7 through the induced draft fan, and the stones contained in the corn kernels are filtered by the separation assembly 405, collected and cleaned into the debris box 6 through the round shell 404, and are cleaned regularly by the staff.

[0042] The impurity removal mechanism 4 also includes a connecting pipe 401, the top of which is fixedly connected to the bottom of the circular shell 404, and one end of the connecting pipe 401 away from the circular shell 404 is fixedly connected to the outer surface of the debris box 6, and a grille 408 is fixedly connected to the side of the inner wall of the processing chamber 8 close to the feed assembly 409, and the top of the feed assembly 409 is rotatably connected to the top of the inner wall of the processing chamber 8.

[0043] The external induced draft fan sucks the corn kernels spread on the ground into the machine body 1 through the grain suction pipe 2, separates the accumulated corn kernels through the feeding assembly 409, and enters the processing chamber 8. The vibrator 403 is turned on to make the separation assembly 405, the buffer assembly 406 and the feeding assembly 409 vibrate intermittently with a small amplitude. At this time, the telescopic rod 407 pulls the feeding assembly 409 to deform it, so that when the corn kernels enter the processing chamber 8, the contact area between the corn kernels and the air is increased, so that the dust attached to the corn kernels is blown into the dust reduction chamber 9 by the blower 3, and the corn kernels coming out of the feeding assembly 409 fall onto the buffer assembly 406. The buffer assembly 406 controls the corn kernels. The feeding speed is increased, and the falling time of the corn kernels is prolonged, so that the dust on the surface is continuously blown into the dust reduction chamber 9 by the blower 3, the dust collection effect is improved, and the working intensity of the separation component 405 is kept moderate. Finally, the corn kernels are thrown out by centrifugal force through the separation component 405, and the separation component 405 classifies and collects the stones contained in the corn kernels. The smaller stones are directly filtered into the round shell 404, and the larger stones are located near the middle of the separation component 405. After being cleaned and entering the round shell 404, they enter the debris box 6, and the corn thrown out of the separation component 405 falls on the grain inclined plate 402, and is discharged from the grain outlet pipe 7 through the induced draft fan.

[0044] The recovery mechanism 5 also includes a nozzle 501, the top of the nozzle 501 is fixedly connected to the top of the inner wall of the dust reduction chamber 9, a feed inlet 502 is opened on the side of the inner wall of the dust reduction chamber 9 close to the grille 408, and a collection box 505 is fixedly connected to the bottom of the sealing shell 503 away from the filter plate 504.

[0045] The blower 3 blows the dust impurities into the dust reduction chamber 9 through the feed port 502, and the nozzle 501 sprays water mist to wet the dust, so that the particles are settled to the bottom of the dust reduction chamber 9 with the water. Not only dust but also a certain amount of corn kernels are blown into the dust reduction chamber 9 by the wind. After being filtered and cleaned by the filter plate 504, the cleaning component 506 cleans the large particles on the filter plate 504 including the corn kernels into the collection box 505, waiting for the staff to clean them out and then recycle the corn kernels, thereby reducing the scattering of dust and recycling the corn kernels blown away by the wind to reduce food waste.

[0046] Embodiment 2, use Figure 1-Figure 9 A dust filtering device for a grain suction machine according to one embodiment of the present invention is described as follows.

[0047] like Figure 1-Figure 9 As shown, a dust filtering device of a grain suction machine described in the present invention is based on the first embodiment, and the feeding component 409 includes a connecting rod 4091, the outer wall of the connecting rod 4091 is fixedly connected to the outer surface of the combing rod 4056, the bottom of the connecting rod 4091 is fixedly connected with a ring 4092, the top of the ring 4092 is symmetrically provided with a cleaning rod 4093, the bottom of the cleaning rod 4093 is fixedly connected to the top of the ring 4092, the top of the cleaning rod 4093 is fixedly connected to a frame 4095, the bottom of the frame 4095 is fixedly connected with a rubber ring 4096, the bottom of the rubber ring 4096 is fixedly connected with an arc-shaped bottom plate 4097, the top of the inner wall of the processing chamber 8 is rotatably connected with a turntable 4094, the outer wall of the turntable 4094 is slidably connected to the outer wall of the cleaning rod 4093, and the bottom of the turntable 4094 is fixedly connected to the top of the frame 4095.

[0048] When the corn kernels are sucked into the grain suction pipe 2, the built-in power system of the body 1 drives the turntable 4094 to rotate, thereby driving the frame 4095 to make the cleaning rod 4093 rotate accordingly. When the corn kernels enter the arc-shaped bottom plate 4097, the telescopic rod 407 cooperates to extend and retract, pulling the rubber ring 4096, so that the holes on the rubber ring 4096 are sometimes larger and sometimes smaller, thereby controlling the feeding speed of the corn kernels to avoid accumulation and also preventing the corn kernels from blocking the grain suction pipe 2 when feeding. The holes evenly arranged on the rubber ring 4096 allow the corn kernels to disperse into the processing chamber 8 after falling from the grain suction pipe 2, thereby increasing the dispersibility of the corn kernels and increasing the area of ​​dust adhered to the surface of the corn kernels in contact with the air. The arc-shaped bottom plate 4097 is the first barrier for the corn when it falls, preventing the corn kernels from falling directly and increasing the time when the blower 3 blows the dust. The cleaning rod 4093 cleans the surface of the grille 408 during the rotation process to avoid large pieces of debris blocking the grille 408 and affecting the collection of dust.

[0049] The buffer assembly 406 includes a fixed frame 4061, the bottom of which is fixedly connected to the outer surface of the driving seat 4053, the top of the fixed frame 4061 is fixedly connected to a rubber disk 4062, the outer wall of the rubber disk 4062 is evenly provided with openings 4063, the outer surface of the fixed frame 4061 is evenly provided with rotating rods 4064, the inner wall of the rotating rod 4064 is rotatably connected to the outer wall of the fixed frame 4061, the bottom of the rotating rod 4064 is fixedly connected to a counterweight ball 4065, and the outer wall of the telescopic rod 407 is fixedly connected to the inner wall of the rubber disk 4062.

[0050] After the corn kernels are dispersed and flow out through the rubber ring 4096, they fall on the rubber disk 4062. The rubber disk 4062 has a large elasticity and is used to adjust the feeding speed of the corn kernels. When the amount of corn kernels is not large, the rubber disk 4062 maintains a normal opening 4063 size. When the corn kernels are piled up, the opening 4063 opened on the surface of the rubber disk 4062 is gradually enlarged by the accumulated corn kernels, so that the corn kernels quickly fall on the surface of the separation component 405. The rubber disk 4062 is the second barrier for the corn kernels in the processing chamber 8, which prolongs the time that the corn kernels stay in the processing chamber 8. The fixed frame 4061 has a built-in power source, which drives the counterweight ball 4065 on the rotating rod 4064 to knock and vibrate the rubber disk 4062, so that the corn kernels are elastically rebounded by the rubber disk 4062, thereby strengthening the mutual friction between the surfaces of the corn kernels, separating the dust from the surfaces of the corn kernels, and improving the dust removal efficiency.

[0051] The separation assembly 405 includes a first motor 4051, the bottom of the first motor 4051 is fixedly connected to the bottom of the inner wall of the round shell 404, the top of the first motor 4051 is fixedly connected to a sieve plate 4052, the top of the inner wall of the sieve plate 4052 is rotatably connected to a drive seat 4053, the inner wall of the drive seat 4053 is evenly provided with baffles 4054, the outer wall of the baffle 4054 is rotatably connected to the inside of the drive seat 4053, the top of the baffle 4054 is rotatably connected to a bent plate 4055, and the bent plate The outer wall of 4055 is slidably connected to the inner wall of the driving seat 4053. The outer surface of the driving seat 4053 is evenly provided with combing rods 4056. The combing rods 4056 stir and rotate when the corn is on the sieve plate 4052, so that the pebbles inside are quickly filtered. The outer wall of the combing rods 4056 is fixedly connected to the outer surface of the driving seat 4053, the bottom of the combing rods 4056 is in contact with the inner wall of the sieve plate 4052, and the top of the driving seat 4053 is fixedly connected to the bottom of the telescopic rod 407.

[0052] The corn kernels dropped from the rubber plate 4062 enter the surface of the sieve plate 4052. When the cleaning rod 4093 rotates, the combing rod 4056 fixedly connected to the connecting rod 4091 is driven to rotate accordingly, so that the driving seat 4053 rotates on the top of the sieve plate 4052. At the same time, the first motor 4051 drives the sieve plate 4052 to rotate. The rotation speed of the sieve plate 4052 is higher than the rotation speed of the combing rod 4056, so that the corn kernels are just subjected to the centrifugal force and are thrown out of the sieve plate 4052. The stones contained in the corn kernels are filtered by the sieve plate 4052 and collected in the round shell 404. The larger stones cannot be thrown out of the sieve plate 4052. During the interval of grain absorption, the driving seat 4053 drives the baffle 4054 to rotate, so that the bottom opening 4063 of the sieve plate 4052 is exposed. Under the vibration of the vibrator 403 and the stirring of the combing rod 4056, the large stones roll to the middle of the bottom of the sieve plate 4052. When the baffle 4054 rotates inward, it drives the bent plate 4055 to extend outward, reducing the corn kernels falling with the large stones. After the stones and a small amount of corn kernels fall into the round shell 404, they enter the debris box 6 through the connecting pipe 401, and the stones in the corn kernels are collected and cleaned, reducing the content of solid debris in the corn kernels.

[0053] The cleaning assembly 506 includes a second motor 5061, the bottom of which is fixedly connected to the top of the filter plate 504, the outer wall of the second motor 5061 is fixedly connected to a special-shaped rod 5062, the inner wall of the special-shaped rod 5062 is provided with a slide groove 5063, the outer surface of the special-shaped rod 5062 is symmetrically provided with support rods 5064, the outer wall of the support rod 5064 is rotatably connected to the inner wall of the special-shaped rod 5062 on the side close to the second motor 5061, the outer wall of the support rod 5064 is fixedly connected to a counterweight block 5066 on the side away from the second motor 5061, the outer surface of the counterweight block 5066 is slidably connected to the inner wall of the slide groove 5063, the outer wall of the support rod 5064 is fixedly connected to a spring 5065 on the side away from the counterweight block 5066, and one end of the spring 5065 away from the support rod 5064 is fixedly connected to the outer wall of the special-shaped rod 5062.

[0054] The filter plate 504 is tilted at the bottom of the sealing shell 503. Initially, the arc-shaped end of the special-shaped rod 5062 is located at the opening 4063 of the sealing shell 503, blocking the water containing dust and reducing the water entering the sealing shell 503. When the dust enters the dust reduction chamber 9 and is sprayed with water mist, the smaller impurities directly pass through the filter plate 504 and enter the bottom of the dust reduction chamber 9, and the larger impurities and corn kernels are collected on the surface of the filter plate 504. After accumulating to a certain amount, the second motor 5061 drives the special-shaped rod 5062 to rotate 180 degrees, and the arc-shaped end of the special-shaped rod 5062 fits with the inner wall of the dust reduction chamber 9 to gather the debris. On the inner side of the arc-shaped end, after rotating 180 degrees, there is no foreign object blocking the collection box 505 and the filter plate 504, and at this time, the support rod 5064 is driven by the counterweight block 5066 and rotates around the special-shaped rod 5062, pushing the debris on the filter plate 504, causing it to roll into the collection box 505 after being subjected to force on the inclined surface, and then the special-shaped rod 5062 returns to its position, and the staff removes the collection box 505 and separates the corn kernels to reduce the corn kernels mixed in the process of dust treatment being processed together, and cleans and collects the recovered corn kernels, reducing the staff's recycling work and reducing waste.

[0055] The specific workflow is as follows:

[0056] During operation, the corn kernels spread on the ground are sucked into the machine body 1 through the grain suction pipe 2 by the external induced draft fan, and the blower 3 is turned on at the same time. The feeding component 409 separates the accumulated corn kernels through the telescopic rod 407, and disperses them into the processing chamber 8 to increase the contact area between the corn kernels and the air, so that the dust attached to the corn kernels is blown into the dust reduction chamber 9 by the blower 3, and the corn kernels coming out of the feeding component 409 fall onto the buffer component 406. The feeding speed of the corn kernels is controlled by the buffer component 406, so that the working intensity of the separation component 405 is kept moderate, and finally the separation component 405 throws the corn kernels out by centrifugal force to make them fall. The grain is discharged from the grain outlet pipe 7 through the induced draft fan onto the inclined plate 402, and the stones contained in the corn kernels are filtered by the separation component 405, collected and cleaned into the debris box 6 through the round shell 404, and the blower 3 blows the dust impurities into the dust reduction chamber 9 through the feed inlet 502, and the nozzle 501 sprays water mist to wet the dust, so that the particles settle to the bottom of the dust reduction chamber 9 with the water. Not only dust but also a certain amount of corn kernels are blown into the dust reduction chamber 9 by the wind. After being filtered and cleaned by the filter plate 504, the cleaning component 506 cleans the large particles on the filter plate 504 including the corn kernels into the collection box 505, waiting for the staff to clean them out and recycle the corn kernels.
