Description

Technical Field

[0001] The present invention relates to the technical field of grain processing, and particularly to a grain processing conveyor device with a grain processing dust removal component. Background Technique

[0002] The conveyor device for grain processing is a key equipment in the processes of grain production, processing and storage and transportation. It is mainly used for automatically and efficiently conveying various grain raw materials (such as wheat, rice, corn, etc.), semi-finished products or finished products, and is also used for conveying grain raw materials to different processing equipment. It mainly includes belt conveyors, vibrating conveyors and screw conveyors, etc., and is an important equipment indispensable in the grain processing process.

[0003] At present, belt conveyors and vibrating conveyors are mainly used in the grain processing process to convey grain raw materials to different processing equipment. During the processes of harvesting, drying and storing of grain raw materials, fine debris and soil will naturally adhere to the surface. And during the conveying process, through collisions, squeezes and frictions, the surface adhesions will be further broken, thus generating more dust. Therefore, during the process of using traditional conveying equipment to convey grain raw materials to different processing equipment, the dust on the grain surface will pollute the environment of the processing site and even cause respiratory infections to the operators. Moreover, the grain raw materials often contain stones of different sizes, and the hardness of the stones is relatively high. After entering the interior of the processing equipment following the grain raw materials, it will aggravate the equipment wear and even shorten the service life.

[0027] The separation component 3 includes a guide plate 301. The position of the guide plate 301 near the rear side is V-shaped and the position near the front side is parallel to the side plate 401. A connecting plate 302 is fixedly connected to the top of the guide plate 301. A regulating rod 303 is rotatably connected to the center of the top of the connecting plate 302. Symmetrically fixedly connected to the top of the connecting plate 302 near the front and rear side edges are limiting rods 304. The outer surfaces of the limiting rods 304 slidably penetrate through the outer surface of the top shell 201 and extend upward. The outer surface of the regulating rod 303 threadedly penetrates through the outer surface of the top shell 201 and extends upward. The bottom of the guide plate 301 does not fit against the top of the conveyor belt 412.

[0028] The screening component 5 includes a main sieve plate 501 and a turntable 510. A connecting block 504 extending rearward is fixedly connected to the bottom of the main sieve plate 501 near the rear side. Connecting shafts 506 are fixedly connected to both outer surfaces of the connecting block 504. The opposite ends of the two connecting shafts 506 penetrate through the avoidance groove 13 and extend outward. The opposite ends of the two connecting shafts 506 are respectively fixedly connected to a first connecting arm 507 and a second connecting arm 508.

A screw rod 503 is threadedly penetrated and connected to the front surface of the main sieve plate 501. The rear end of the screw rod 503 is rotatably connected to the front surface of the secondary sieve plate 502.

The rear surfaces of the two partition plates 203 are slidably fitted to the positions near both sides of the front surface of the guide plate 301. The outer surfaces of both sides of the two partition plates 203 and the main sieve plate 501 are slidably fitted. The bottom of the converging baffle 205 is slidably fitted to the top of the conveyor belt 412.

[0030] The present invention is used in steps. When in use, the fan 207, the first motor 208 and the second motor 402 are started, and a cloth bag is put on the lower end outlet of the dust exhaust pipe 210 and fixed. When the second motor 402 is started and drives the driving shaft 408 to rotate, the fourth gear 409, the fifth gear 410 and the sixth gear 411 on the surface of the driving shaft 408 are meshed with the third gear 407, the second gear 406 and the first gear 405 on the surface of the five active rollers 403, so as to achieve the effect of driving all the active rollers 403 to rotate. At this time, the active rollers 403 cooperate with the corresponding driven rollers 404 to drive the five parallel conveyor belts 412 to move, and then the food raw materials are put into the feed hopper 204 and fall on the conveyor belt 412 for forward transportation. After the fan 207 is started, The dust suction holes 202 arranged below the top shell 201 will suck the dust particles in the food raw materials into the top shell 201 and flow toward the direction of the fan 207 along the airflow. When the dust reaches the semicircular filter screen 206, it will be blocked and retained on the rear curved surface of the semicircular filter screen 206 under the action of the airflow. When the first motor 208 is started and drives the auger blade 209 to rotate, the dust adsorbed on the surface of the semicircular filter screen 206 will be transported to the bag through the dust exhaust pipe 210 for collection under the conveying action of the auger blade 209, which effectively solves the problem that the dust generated when the food raw materials move on the conveying device will pollute the processing environment and even cause respiratory infections to the operators. In addition, the volume of the same food raw materials is The grains are similar in volume, and when they fall onto the conveyor belt 412 through the feed hopper 204, they will be gathered onto the middle conveyor belt 412 under the action of the gathering baffle 205. As the grain raw materials are conveyed forward to the guide plate 301, the larger stones and other debris are higher than the volume of the grain raw materials, and therefore cannot pass through the gap between the bottom of the guide plate 301 and the conveyor belt 412. At this time, the large stones will move forward along the inclined surface of the guide plate 301, and finally move to the conveyor belt 412 at the far side. In the process of moving along the inclined surface of the front side of the guide plate 301, the stones will entrain a part of the grain and move sideways at the same time. The active rollers 403 inside the different conveyor belts 412 are connected by the first gear 405, the second gear 406 and the third gear 407 and the sixth gear The wheel 411, the fifth gear 410 and the fourth gear 409 are connected by transmission, and the fourth gear 409 meshing with each other near the middle position has a larger number of teeth than the third gear 407, which has an acceleration effect. The sixth gear 411 near the side has a smaller number of teeth than the first gear 405, which has a deceleration effect. The fifth gear 410 between the fourth gear 409 and the sixth gear 411 has the same number of teeth as the second gear 406, and the two have the same rotation speed. Therefore, the movement speed of the conveyor belt 412 on the outside is lower than that of the conveyor belt 412 on the inside. When the grain raw materials entrained by the stones and moving to the outer conveyor belt 412 are in contact with the two conveyor belts 412 at the same time, the conveyor belt 412 with a faster inner movement speed will generate traction on the grain and the stones.The conveyor belt 412 with a slower outer conveying speed will generate a reverse resistance. Since the height of the stones is relatively high and they are not allowed to pass through the gap between the guide plate 301 and the conveyor belt 412, the stones will continue to move obliquely at this time. The grains pass through the guide plate 301 and move irregularly onto the middle three conveyor belts 412 and continue to be conveyed forward. Subsequently, the large stones are blocked by the two sides of the guide plate 301 and the partition plate 203, and then directly fall from the positions on both sides inside the enclosure 1 into the lower collection shell 12 below. The grain raw materials on the middle three conveyor belts 412 will fall from the position between the two partition plates 203 onto the inclined main sieve plate 501. At this time, during the process of the grain raw materials rolling down to a lower place, the smaller stones and impurities will fall into the lower collection shell 12 through the overlapping holes on the surfaces of the main sieve plate 501 and the auxiliary sieve plate 502. Finally, the grain raw materials on the main sieve plate 501 will fall through the front opening 11 into the corresponding processing equipment to complete the conveying operation. And during the conveying process, stones and other impurities with different volumes from the grain raw materials can be stably removed, avoiding damage to the subsequent processing equipment and even causing equipment failures. Also, at the same time, according to different types of grain raw materials, by rotating the adjusting rod 303, the connecting plate 302 and the guide plate 301 can be driven to lift under the action of the thread, so as to adjust the gap between the bottom of the grain raw materials and the guide plate 301 and the top of the conveyor belt 412 to a matching state. Subsequently, by rotating the screw rod 503, the auxiliary sieve plate 502 can be driven to slide back and forth at the bottom of the main sieve plate 501 under the action of the thread, so that the overlapping area between the two sieve plates matches the volume of the grains. The adjustment method is simple, meeting the conveying requirements during the processing of different types of grains, improving the use effect of the device. During the lifting process of the connecting plate 302 and the guide plate 301, the limiting rod 304 plays a limiting role to ensure the stable posture of the guide plate 301. When stones and other impurities fall into the inside of the collection shell 12, the collection shell 12 can be taken out and cleaned by means of pulling, and the usage method is simple.

[0031] Embodiment 2: As Figures 1 - 8 shown, the difference based on the combination of the embodiments is that the turntable 510 is fixedly connected to the end of the drive shaft 408 away from the second motor 402. An eccentric shaft 511 is rotatably connected to an eccentric position on the outer surface of the turntable 510. A third connecting arm 509 is rotatably sleeved on the outer surface of the eccentric shaft 511. One end of the third connecting arm 509 away from the eccentric shaft 511 is rotatably connected to the bottom end of the second connecting arm 508.

[0032] Arc-shaped avoidance grooves 13 are respectively formed at positions near the middle on the outer surfaces of both sides of the enclosure 1. A crescent block 505 is fixedly connected to the position near the rear side of the top of the main sieve plate 501. The rear surface of the crescent block 505 near the top is in sliding fit with the outer surface of the conveyor belt 412.

[0033] During the process of the second motor 402 driving the drive shaft 408 to rotate in the use steps of the present invention, the drive shaft 408 will simultaneously drive the turntable 510 with a smaller end diameter to rotate. When the turntable 510 rotates, it will perform an eccentric motion through the eccentric shaft 511 on the surface. At the same time, the eccentric shaft 511 will drive the rear end of the third connecting arm 509 to perform a small-range circular motion. The main sieve plate 501 is rotationally connected to the second fixed shaft 421 through the bottom connecting block 504, the connecting shaft 506, and the first connecting arms 507 and the second connecting arms 508 on both sides. Therefore, the main sieve plate 501 can rotate around the second fixed shaft 421. The bottom end of the second connecting arm 508 and the front end of the third connecting arm 509 are rotationally connected. Therefore, during the process of the front end of the third connecting arm 509 performing a small-range circular motion, it will simultaneously drive the lower end of the second connecting arm 508 to perform a slight reciprocating swing back and forth. At this time, the main sieve plate 501 will be in a state of bouncing up and down, which can effectively prevent the grain raw materials from getting stuck on the surface of the main sieve plate 501, ensuring smooth feeding and eliminating the need for additional power equipment, which has the effect of energy saving and efficiency improvement. When the second connecting arm 508 swings back and forth around the second fixed shaft 421, the connecting shaft 506 will simultaneously slide in the avoidance groove 13 without being blocked. When the main sieve plate 501 receives the grain raw materials dropped on the conveyor belt 412, the design of the crescent block 505 can reduce the gap between the conveyor belt 412 and the main sieve plate 501 to avoid material leakage. At the same time, when the main sieve plate 501 swings around the second fixed shaft 421, the crescent block 505 simultaneously moves around the second fixed shaft 421. The front side of the conveyor belt 412 near the crescent block 505 is semicircular. Therefore, the crescent block 505 will not have excessive contact with the conveyor belt 412.

[0034] Embodiment 3: As Figures 1 - 4 and Figure 6 shown, the difference based on the combination of the embodiments lies in that a central shaft 419 is rotatably connected at a position near the middle between the outer surfaces of the two side plates 401. A rocker 417 is rotatably connected to the outer surface of the central shaft 419. The rocker 417 is located between the inner walls of the plurality of conveyor belts 412 and the rocker 417 is close to the inner top of the conveyor belt 412. An opening 418 is formed at a position near the rear side of the outer surface of the rocker 417.

[0035] A mounting plate 413 is fixedly connected at a position near the rear side between the inner walls of the two side plates 401. A gear rack 414 is fixedly connected near the center of the top of the mounting plate 413. Driven gears 415 are rotatably connected to both outer surfaces of the gear rack 414. The two driven gears 415 are fixedly connected by a shaft. Eccentric rods 416 are fixedly connected to the eccentric positions on the opposite outer surfaces of the two driven gears 415. The eccentric rods 416 are inserted between the inner walls of the opening 418. The outer surface of the driven gear 415 is meshed with the outer surface of the fourth gear 409. A reserved opening is formed at the overlapping position of the rocker 417 and the driven gear 415.

[0036] In the using steps of the present invention, when the drive shaft 408 drives the fourth gear 409 to rotate, the fourth gear 409 will simultaneously drive the driven gear 415 meshing with it to rotate. When the driven gear 415 rotates, since the eccentric rod 416 on the surface is slidably inserted into the opening 418 at the rear side of the rocker 417, and the middle position of the rocker 417 is rotatably connected to the side plate 401 through the central shaft 419, when the height changes during the movement of the eccentric rod 416, it will simultaneously drive the rocker 417 to swing up and down with the central shaft 419 as the center. During the process, when the front and rear ends of the rocker 417 swing to the highest position, they will impact the front side and the rear side of the conveyor belt 412, thereby vibrating and dispersing the accumulated materials, ensuring the conveying effect, and no additional power equipment is required. The mounting plate 413 is used to connect the gear rack 414 and the two side plates 401. The two driven gears 415 are fixed by shafts, and the shafts connecting the driven gears 415 pass through the inside of the gear rack 414, achieving the purpose of rotatably connecting the driven gears 415 and the gear rack 414.

[0037] In addition, the volumes of similar grain raw materials are similar. When they fall onto the conveyor belt 412 through the feed hopper 204, they will be gathered above the middle conveyor belt 412 under the action of the gathering baffle 205. As the grain raw materials are conveyed forward to the guide plate 301, larger stones and other debris are higher than the volume of the grain raw materials and cannot pass through the gap between the bottom of the guide plate 301 and the conveyor belt 412. At this time, the large stones will move forward along the inclined surface of the guide plate 301 and finally move to the conveyor belt 412 on the far side. In the process of moving along the inclined surface of the front side of the guide plate 301, the stones will entrain a part of the grain and move sideways at the same time, while different conveyors The driving roller 403 inside the conveyor belt 412 is connected to the sixth gear 411, the fifth gear 410 and the fourth gear 409 by transmission, and the fourth gear 409 near the middle position meshing with each other has a larger number of teeth than the third gear 407, which has an acceleration effect, and the sixth gear 411 near the side has a smaller number of teeth than the first gear 405, which has a deceleration effect, and the fifth gear 410 between the fourth gear 409 and the sixth gear 411 has the same number of teeth as the second gear 406, and the two have the same rotation speed, so the movement speed of the conveyor belt 412 on the outside is slower than that of the conveyor belt 412 on the inside. 2 movement speed, and when the grain raw materials carried by the stones and moved to the outer conveyor belt 412 are in contact with the two conveyor belts 412 at the same time, the inner conveyor belt 412 with a faster movement speed will generate traction on the grain and the stones, while the outer conveyor belt 412 with a slower transportation speed will generate reverse resistance, and the stones are too high to pass through the gap between the guide plate 301 and the conveyor belt 412. At this time, the stones will continue to move obliquely, and the grains will pass through the guide plate 301 irregularly and move to the middle three conveyor belts 412 to continue to be transported forward. Then the large stones pass through the two sides of the guide plate 301 and are blocked by the partition plate 203, and then from the positions on both sides of the inner side of the surrounding shell 1. The grains on the three conveyor belts 412 in the middle will fall from the position between the two partition plates 203 to the inclined main sieve plate 501. At this time, the grains will roll down, and smaller stones and impurities will fall into the collecting shell 12 below through the overlapping holes on the surface of the main sieve plate 501 and the auxiliary sieve plate 502. Finally, the grains on the main sieve plate 501 will fall into the corresponding processing equipment through the open port 11 on the front side, completing the conveying operation. In addition, stones and other impurities with different volumes from the grains can be stably removed during the conveying process to avoid damage to subsequent processing equipment or even equipment failure. Meanwhile, according to different types of grain raw materials, the adjusting rod 303 can be rotated, and under the action of the thread, the connecting plate 302 and the guiding plate 301 can be driven to rise and fall, so as to adjust the gap between the grain raw materials and the top of the conveyor belt 412 at the bottom of the guiding plate 301 to a matching state. Subsequently, after the screw 503 is rotated, under the action of the thread, the auxiliary sieve plate 502 can be driven to slide back and forth at the bottom of the main sieve plate 501, so that the overlapping area between the two sieve plates matches the grain volume. The adjustment method is simple, meeting the conveying requirements during the processing of different types of grains, improving the use effect of the device. During the rising and falling process of the connecting plate 302 and the guiding plate 301, the limiting rod 304 plays a limiting role, ensuring the stable attitude of the guiding plate 301; During the process of the second motor 402 driving the driving shaft 408 to rotate, the driving shaft 408 will simultaneously drive the turntable 510 with a smaller diameter at the end to rotate. When the turntable 510 rotates, it will perform eccentric motion through the eccentric shaft 511 on the surface. At the same time, the eccentric shaft 511 will drive the rear end of the third connecting arm 509 to perform a small-range circular motion. The main sieve plate 501 is rotationally connected to the second fixed shaft 421 through the bottom connecting block 504, the connecting shaft 506 and the first connecting arms 507 and the second connecting arms 508 on both sides. Therefore, the main sieve plate 501 can rotate around the second fixed shaft 421. The bottom end of the second connecting arm 508 is rotationally connected to the front end of the third connecting arm 509. Therefore, during the process of the front end of the third connecting arm 509 performing a small-range circular motion, it will simultaneously drive the lower end of the second connecting arm 508 to perform a slight reciprocating swing back and forth. At this time, the main sieve plate 501 will be in a state of jolting up and down, which can effectively prevent the grain raw materials from getting stuck on the surface of the main sieve plate 501, ensuring smooth feeding and not requiring additional power equipment, playing a role in energy conservation and efficiency improvement; Meanwhile, when the driving shaft 408 drives the fourth gear 409 to rotate, the fourth gear 409 will simultaneously drive the driven gear 415 meshing with it to rotate. When the driven gear 415 rotates, since the eccentric rod 416 on the surface is slidably inserted into the opening 418 at the rear side of the rocker 417, and the middle position of the rocker 417 is rotationally connected to the side plate 401 through the central shaft 419, when the height of the eccentric rod 416 changes during the movement process, it will simultaneously drive the rocker 417 to swing up and down around the central shaft 419. During the process, when the front and rear ends of the rocker 417 swing to the highest position, they will hit the front side and the rear side of the conveyor belt 412, thereby vibrating and dispersing the accumulated materials, ensuring the conveying effect and not requiring additional power equipment.
