Description

Technical Field

[0001] The invention relates to the technical field of grain processing, in particular to a grain processing conveying device with a grain processing dust removal component. Background Art

[0002] Conveying devices for grain processing are key equipment in the grain production, processing, storage and transportation process. They are mainly used to automatically and efficiently convey various types of grain raw materials (such as wheat, rice, corn, etc.), semi-finished products or finished products. They are also used to transport grain raw materials to different processing equipment. They mainly include belt conveyors, vibrating conveyors and screw conveyors, etc., and are indispensable and important equipment in the grain processing process.

[0003] At present, belt conveyors and vibrating conveyors are mainly used in the grain processing process to transport grain raw materials to different processing equipment. During the harvesting, drying and storage of grain raw materials, fine debris and soil will naturally adhere to the surface. In addition, collision, extrusion and friction during transportation will further cause the surface adhesions to break, thereby generating a lot of dust. Therefore, when using traditional conveying equipment to transport grain raw materials to different processing equipment, the dust on the surface of the grain will pollute the environment of the processing site and even cause respiratory infections in operators. In addition, grain raw materials are often mixed with stones of different sizes, and the hardness of the stones is relatively high. After entering the processing equipment with the grain raw materials, it will aggravate equipment wear and even shorten its service life.

[0042] The screening assembly 5 includes a main screen plate 501 and a turntable 510.

[0044] The present invention is used in the following 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 drive shaft 408 to rotate, the fourth gear 409, the fifth gear 410 and the sixth gear 411 on the surface of the drive 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, thereby 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 grain 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 collecting 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 fan 207 along with the air flow. When the dust reaches the semicircular filter 206, it will be blocked and retained on the rear arc surface of the semicircular filter 206 under the action of the air flow. When the first motor 208 starts and drives the auger blade 209 to rotate, the dust adsorbed on the surface of the semicircular filter 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 of the operators. In addition, the volume of the same food raw materials is relatively small. The grains are similar in volume. 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 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. 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 in transmission, and the fourth gear 409 meshing with each other near the middle 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 rotate at the same speed. Therefore, the movement speed of the outer conveyor belt 412 is lower than that of the inner conveyor belt 412. When the grain raw materials entrained by the stones and moving to the outer conveyor belt 412 contact 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 stones.The conveyor belt 412 with a slower transport speed on the outside will generate reverse resistance, and the high height of the stones will not allow them 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, while the grain will pass through the guide plate 301 and move irregularly to the three middle conveyor belts 412 to continue to be transported forward. Then the large stones will pass through the two sides of the guide plate 301 and be blocked by the partition plate 203, and then fall directly from the positions on both sides of the inner side of the surrounding shell 1 to the collection shell 12 below, while the grain raw materials on the three middle conveyor belts 412 will fall from the position between the two partition plates 203 to the inclined main screen plate 501. At this time, the grain raw materials will roll to the bottom, and smaller stones and impurities will pass through the overlapping holes on the surface of the main screen plate 501 and the auxiliary screen plate 502 and fall into the collection shell 12 below. Finally, the grain raw materials on the main screen plate 501 will fall into the corresponding processing equipment through the open port 11 on the front side, completing the conveying operation, and can be stably cleared during the conveying process. Impurities such as stones that are different in volume from the grain raw materials can be removed to avoid damage to subsequent processing equipment or even equipment failure. At the same time, according to different types of grain raw materials, the connecting plate 302 and the guide plate 301 can be driven up and down by rotating the adjusting rod 303 under the action of the thread, so that the gap between the grain raw materials and the bottom of the guide plate 301 and the top of the conveyor belt 412 can be adjusted to a matching state. Subsequently, the auxiliary screen plate 502 can be driven to slide back and forth on the bottom of the main screen plate 501 under the action of the thread after rotating the screw 503, so that the overlapping area between the two screen plates matches the grain volume. The adjustment method is simple, which meets the transportation requirements of different types of grain processing and improves the use effect of the device. During the lifting and lowering process of the connecting plate 302 and the guide plate 301, the limit rod 304 plays a limiting role to ensure that the guide plate 301 is stable. When impurities such as stones fall into the collection shell 12, the collection shell 12 can be taken out and cleaned by pulling. It is simple to use.

[0045] Example 2: Figures 1-8 As shown, the difference between the embodiment and the embodiment is that the turntable 510 is fixedly connected to the end of the drive shaft 408 away from the second motor 402, and the eccentric shaft 511 is rotatably connected to the eccentric part of the outer surface of the turntable 510, and the third connecting arm 509 is rotatably sleeved on the outer surface of the eccentric shaft 511, and the 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.

[0046] Arc-shaped avoidance grooves 13 are provided near the middle of the outer surfaces of both sides of the surrounding shell 1, and a crescent block 505 is fixedly connected to the top of the main screen plate 501 near the rear side, and the rear surface of the crescent block 505 near the top is slidably fitted with the outer surface of the conveyor belt 412.

[0047] The usage steps of the present invention are as follows: when the second motor 402 drives the drive shaft 408 to rotate, the drive 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 of circular motion. The main sieve plate 501 is coordinated with the second fixed shaft 421 through the bottom connecting block 504, the connecting shaft 506 and the first connecting arm 507 and the second connecting arm 508 on both sides to form a rotational connection. Therefore, the main sieve plate 501 can rotate with the second fixed shaft 421 as the center of the circle, and the bottom end of the second connecting arm 508 is rotationally connected to the front end of the third connecting arm 509. Therefore, when the front end of the third connecting arm 509 performs a small range of circular motion, it will simultaneously drive the lower end of the second connecting arm 508 to swing slightly back and forth. At this time, the main sieve plate 501 will be in an up and down bumping state, which can effectively prevent the grain raw materials from being stuck on the surface of the main sieve plate 501, ensuring smooth material unloading and without 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 with the second fixed shaft 421 as the center, the connecting shaft 506 will slide in the avoidance groove 13 at the same time without obstruction. 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 with the second fixed shaft 421 as the center, the crescent block 505 also moves with the second fixed shaft 421 as the center, and the position of the front side of the conveyor belt 412 near the crescent block 505 is semicircular, so the crescent block 505 will not have excessive contact with the conveyor belt 412.

[0048] Example 3: Figures 1-4 and Figure 6 As shown, the difference between the embodiment and the basis is that a center shaft 419 is rotatably connected between the outer surfaces of the two side panels 401 near the middle, and the outer surface of the center shaft 419 is rotatably connected to a rocker 417, which is located between the inner walls of multiple conveyor belts 412 and the rocker 417 is close to the inner top of the conveyor belt 412, and an opening 418 is provided on the outer surface of the rocker 417 near the rear side.

[0049] A mounting plate 413 is fixedly connected between the inner walls of the two side plates 401 near the rear side, a gear rack 414 is fixedly connected to the top of the mounting plate 413 near the center, the outer surfaces of both sides of the gear rack 414 are rotatably connected to driven gears 415, the two driven gears 415 are fixedly connected by an axis, and the eccentric parts of the outer surfaces of the opposite sides of the two driven gears 415 are fixedly connected to eccentric rods 416, 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, and a reserved opening is opened at the overlapping part of the rocker plate 417 and the driven gear 415.

[0050] The present invention is used in the following steps: 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, the eccentric rod 416 on the surface slides and is inserted into the opening 418 on 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 axis 419. Therefore, when the height of the eccentric rod 416 changes during the movement, it will simultaneously drive the rocker 417 to rotate around the central axis 419. The center of the gear 415 swings up and down. During the process, when the front and rear ends of the rocker 417 swing to the highest point, they will hit the front and rear sides of the conveyor belt 412, thereby vibrating the accumulated materials and ensuring the conveying effect. 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 an axis, and the axis connecting the driven gears 415 passes through the inside of the gear rack 414, so as to achieve the purpose of rotating the driven gears 415 and the gear rack 414.

[0051] The effect and working principle of the entire mechanism are as follows: when using the device to transport food raw materials, first start the fan 207, the first motor 208 and the second motor 402, and use a cloth bag to cover the lower end outlet of the dust exhaust pipe 210 and fix it. When the second motor 402 is started and drives the drive shaft 408 to rotate, the fourth gear 409, the fifth gear 410 and the sixth gear 411 on the surface of the drive 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, thereby 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 to move. When the food is conveyed forward, the fan 207 is started to suck the air inside the top shell 201. At this time, 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 fan 207 along the airflow. When the dust reaches the semicircular filter 206, it will be blocked and retained on the rear curved surface of the semicircular filter 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 206 will be transported to the inside of the dust exhaust pipe 210 under the conveying action of the auger blade 209 and then enter the cloth bag for collection, 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 of the operators.

[0052] In addition, the volume of similar grain raw materials is 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 position of 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 outermost conveyor belt 412. 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, and different conveyors will move sideways at the same time. 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 the first gear 405, the second gear 406 and the third gear 407. The fourth gear 409, which is meshed with each other near the middle, has a larger number of teeth than the third gear 407, and has an accelerating effect. The sixth gear 411, which is near the side, has a smaller number of teeth than the first gear 405, and has a decelerating 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 slower than that of the conveyor belt 41 on the inside. 2 movement speed, and when the grain raw materials carried by the stones and moved to the outer conveyor belt 412 come into contact with the two conveyor belts 412 at the same time, the inner conveyor belt 412 with a faster movement speed will generate traction for the grain and stones, while the outer conveyor belt 412 with a slower movement speed will generate reverse resistance. 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, while the grain passes through the guide plate 301 and moves irregularly to the three middle 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 move from the position on both sides of the interior of the surrounding shell 1. The grains on the three conveyor belts 412 in the middle will fall directly into the collecting shell 12 below, while 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 downwards, and smaller stones and impurities will pass through the overlapping holes on the surfaces of the main sieve plate 501 and the auxiliary sieve plate 502 and fall into the collecting shell 12 below. 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, during the conveying process, stones and other impurities that are different in volume from the grains can be stably removed to avoid damage to subsequent processing equipment or even equipment failure.

[0053] At the same time, according to different types of grain raw materials, the connecting plate 302 and the guide plate 301 can be driven up and down by rotating the adjusting rod 303 under the action of the thread, so that the gap between the grain raw material and the bottom of the guide plate 301 and the top of the conveyor belt 412 is adjusted to a matching state, and then the auxiliary sieve plate 502 is driven to slide back and forth on the bottom of the main sieve plate 501 under the action of the thread after rotating the screw 503, so that the overlapping area between the two sieve plates matches the volume of the grain. The adjustment method is simple, meets the transportation requirements of different types of grain processing, and improves the use effect of the device. During the lifting and lowering process of the connecting plate 302 and the guide plate 301, the limit rod 304 plays a limiting role to ensure the stability of the guide plate 301.

[0054] When the second motor 402 drives the drive shaft 408 to rotate, the drive 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 of circular motion. The main sieve plate 501 is connected to the second fixed shaft 421 through the bottom connecting block 504, the connecting shaft 506 and the first connecting arm 507 and the second connecting arm 508 on both sides to form a rotation connection. The main sieve plate 501 can rotate with the second fixed axis 421 as the center of the circle, and the bottom end of the second connecting arm 508 is rotatably connected to the front end of the third connecting arm 509. Therefore, when the front end of the third connecting arm 509 performs a small-range circular motion, it will simultaneously drive the lower end of the second connecting arm 508 to swing back and forth slightly. At this time, the main sieve plate 501 will be in an up and down bumpy state, which can effectively prevent the grain raw materials from getting stuck on the surface of the main sieve plate 501, ensuring smooth material discharge without the need for additional power equipment, and having the effect of energy saving and efficiency improvement.

[0055] At the same time, when the driving shaft 408 drives the fourth gear 409 to rotate, the fourth gear 409 will simultaneously drive the driven gear 415 engaged with it to rotate. When the driven gear 415 rotates, the eccentric rod 416 on the surface slides and is inserted into the opening 418 on 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 axis 419. Therefore, when the height of the eccentric rod 416 changes during the movement, it will simultaneously drive the rocker 417 to swing up and down with the central axis 419 as the center. During the process, when the front and rear ends of the rocker 417 swing to the highest point, they will hit the front and rear sides of the conveyor belt 412, thereby vibrating and dispersing the accumulated materials, ensuring the conveying effect, and without the need for additional power equipment.
