Description

Technical Field

[0001] This invention belongs to the field of grain conveying technology, specifically a mixing and conveying device for producing grain products. Background Technology

[0002] A mixing and conveying device for producing coarse grain foods aims to efficiently and uniformly mix and convey various coarse grain raw materials (such as oats, quinoa, brown rice, black rice, red beans, mung beans, etc.) according to a preset formula ratio, and finally stably and continuously convey the mixed coarse grain materials to the next processing equipment, which greatly improves production efficiency and ensures the accuracy of product formula and batch-to-batch stability.

[0003] In the field of coarse grain food processing, screw conveyors are widely used for horizontal or inclined conveying of materials such as grains, beans, and millet due to their simple structure, good sealing, and low cost. However, when conveying small-particle, low-strength coarse grain materials such as millet, the tiny particles and impurities attached to the material itself, as well as the continuous friction, compression, and collision between the screw blades and the material, the material and the shell, and between the material particles during the conveying process, cause damage to the surface of the material or overall breakage, thereby generating new dust. This dust will permeate the equipment cavity under the vibration of the equipment operation and the disturbance of internal airflow, and escape from the gaps in the equipment, polluting the workshop environment. Furthermore, high concentrations of dust will invade key components such as transmission bearings, aggravating their wear, leading to an increased failure rate and shortened lifespan of the equipment.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0036] As shown in Figures 1 to 7 , the mixed conveying device for producing coarse cereal food described in the embodiments of the present application comprises a conveying device 1, a conveying cavity 5 arranged inside the conveying device 1, and a feed pipe 2 extending to the conveying cavity 5;

[0037] The inside of the conveying cavity 5 is provided with an auger, and the coarse cereal is poured into the conveying cavity 5 through the feed pipe 2 and is conveyed by the auger. ​​

[0038] The inside of the conveying device 1 is fixedly provided with a dedusting box 6, the bottom of the dedusting box 6 is provided with an air hole 17 for communicating with the conveying cavity 5, and the inside of the dedusting box 6 is divided into a plurality of impurity cavities 7 by a plurality of partitions 8;

[0039] When the auger conveys the coarse grains, the dust generated at this time can be sucked into the inside of the dedusting box 6 through the air hole 17 provided at the bottom of the dedusting box 6, the plurality of impurity cavities 7 correspond to different positions of the conveying cavity 5 respectively, and the conveying cavity 5 is covered as much as possible, so as to realize efficient dust removal.

[0040] The outside of the conveying device 1 is provided with a negative pressure pipe 11, the plurality of impurity cavities 7 are in communication with the inner cavity of the negative pressure pipe 11, and the negative pressure pipe 11 is connected with a negative pressure assembly;

[0041] The inner cavities of the plurality of impurity cavities 7 are not communicated with each other, the plurality of impurity cavities 7 are in communication with the inner cavity of the negative pressure pipe 11, so that the inner cavity of the negative pressure pipe 11 is in a negative pressure state through the negative pressure assembly, the inner cavities of the plurality of impurity cavities 7 are also in a negative pressure state at the same time, and then the dust generated when the coarse grains are transported in the conveying cavity 5 is sucked in, the dust escaping from the equipment is reduced, the workshop environment is purified, the wear of the equipment caused by the dust is reduced, and the equipment failure rate is reduced.

[0042] The inside of the conveying device 1 is rotatably provided with a belt 10, the two ends of the belt 10 are rotatably provided with first belt pulleys 12, and the inside of each of the plurality of impurity cavities 7 is slidably provided with a second belt pulley 24;

[0043] Under normal circumstances, the second belt pulley 24 is located above the belt 10, when the second belt pulley 24 slides downward, the second belt pulley 24 is engaged with the belt 10, at this time, the rotation of the second belt pulley 24 can drive the first belt pulley 12 to rotate through the belt 10.

[0044] The inside of the conveying device 1 is slidably provided with a cleaning block 9 which is provided with a cavity and an opening at the top, and the belt 10 and the dedusting box 6 are located in the inside of the cleaning block 9;

[0045] The inner wall of the cleaning block 9 is attached to the bottom end of the dedusting box 6, the end of the cleaning block 9 close to the dedusting box 6 is provided with an air port 45, and the cleaning block 9 is in communication with the negative pressure pipe 11 through a connecting assembly;

[0046] When the cleaning block 9 slides outside the impurity removal box 6, the inner wall of the cleaning block 9 will scrape the bottom of the impurity removal box 6 first, and the attached impurities can be scraped off. The size of the cleaning block 9 can just cover the area of one of the impurity cavities 7. When the cleaning block 9 is just located directly below one of the impurity cavities 7, the air port 45 (which can be a strip or a hole, and can be designed by those skilled in the art according to the needs) on the cleaning block 9 is directly opposite the air hole 17 of the current impurity cavity 7. At this time, the inner cavity of the cleaning block 9 is in communication with the inner cavity of the current impurity cavity 7. Since the inner cavity of the cleaning block 9 is in communication with the negative pressure pipe 11 through the connecting assembly, when the negative pressure pipe 11 is in negative pressure due to the start of the negative pressure assembly, the inner cavity of the cleaning block 9 will also be in negative pressure. In addition, the air port 45 on the cleaning block 9 is located below the impurity removal box 6, and the airflow flows towards the inside of the cleaning block 9. Therefore, the air hole 17 on the impurity removal box 6 can be back-sucked, which facilitates the suction of the impurities blocked in the air hole 17, and further ensures the flow of the air hole 17 and the normal use of the impurity cavity 7.

[0047] One end of the cleaning block 9 is fixedly installed with a magnetic block 27 for magnetic attraction with the belt 10, and the other end of the cleaning block 9 is fixedly installed with a limiting block 28 for limiting the belt 10. The diameter of the second belt pulley 24 is larger than that of the first belt pulley 12.

[0048] One side of the belt 10 is fixedly installed with a magnetic plate for mutual attraction with the magnetic block 27. The belt 10 can drive the cleaning block 9 to slide in the inside of the conveying device 1 through the attraction of the magnetic force. Since the diameter of the second belt pulley 24 is larger than that of the first belt pulley 12, when the second belt pulley 24 slides downward and controls the rotation of the belt 10, the two sides of the belt 10 will be stretched outward at this time. Under the action of the magnetic force, the cleaning block 9 slides synchronously until the cleaning block 9 drives the limiting block 28 to slide to the position of the second belt pulley 24 which slides downward. The cleaning block 9 cooperates with the limiting block 28 to apply a pressing force from the outside to the inside of the belt 10, and at the same time limits the rotation of the second belt pulley 24. At this time, the cleaning block 9 will be located directly below one of the impurity cavities 7 (each impurity cavity 7 is provided with a second belt pulley 24 and is located at the center position of the impurity cavity 7), which facilitates the cleaning block 9 to cooperate with the negative pressure assembly to suck the impurities blocked in the air hole 17.

[0049] When the air hole 17 in one of the impurity cavities 7 is blocked, the air flow entering the impurity cavity 7 from the conveying cavity 5 will be reduced. By controlling the second belt pulley 24 to slide downward and engage with the belt 10, and then rotating the belt 10, the cleaning block 9 is moved to the position below the impurity cavity 7 with reduced air flow, and cooperates with the negative pressure assembly to suck the impurities blocked in the air hole 17, so as to ensure the dust removal efficiency of the impurity removal box 6 on the conveying cavity 5.

[0050] When the second pulley 24 slides upward and disengages from the belt 10, the belt 10 resets, the cleaning block 9 drives the limiting block 28, which is no longer blocked, and can continue to slide inside the conveying device 1.

[0051] As a preferred embodiment of the present application, the inside of the miscellaneous cavity 7 is fixedly provided with a three-way air pipe 31, one end of the three-way air pipe 31 penetrates the miscellaneous removal box 6 and extends to the inside of the negative pressure pipe 11, the bottom end of the second pulley 24 is fixedly provided with a transmission rod 26, one end of the transmission rod 26 extends to the inside of the three-way air pipe 31 and is fixedly provided with a piston 32, and the top end of the piston 32 is provided with a reset spring.

[0052] Through the cooperation of the piston 32 and the reset spring, the transmission rod 26 drives the second pulley 24 to maintain the state of engagement with the belt 10, and the piston 32 is also located below the communication position of the three-way air pipe 31. Since the transverse end of the three-way air pipe 31 extends to the inside of the negative pressure pipe 11, when the negative pressure assembly is started and the inner cavity of the negative pressure pipe 11 is in a negative pressure state, the inside of the three-way air pipe 31 will also be in a negative pressure state. Under the action of air pressure, the piston 32 located below the communication position of the three-way air pipe 31 will slide upward under the action of air pressure until it slides to the inner cavity communication position of the three-way air pipe 31. At this time, the inside of the miscellaneous cavity 7 is in a negative pressure state, and when the piston 32 slides upward, the second pulley 24 can be driven to slide upward and disengage from the belt 10 through the transmission rod 26. Therefore, when the air hole 17 in the miscellaneous cavity 7 is not blocked and the air flow remains at a certain level, the second pulley 24 in the current miscellaneous cavity 7 will be located above the belt 10. When the air hole 17 in the miscellaneous cavity 7 is blocked and the air flow decreases to a normal level, the corresponding three-way air pipe 31 cannot control the piston 32 to be located at the communication position of the three-way air pipe 31 through air pressure. At this time, the piston 32 will slide downward under the action of the reset spring, and the second pulley 24 will slide downward and engage with the belt 10 through the cooperation of the transmission rod 26. Through the rotation of the second pulley 24, the belt 10 can control the cleaning block 9 to slide to the lower side of the current miscellaneous cavity 7 under the action of the magnetic force. Finally, the cleaning block 9 cooperates with the negative pressure assembly to suck the impurities blocking the air hole 17 and dredge the air hole 17. Through the reduction of the air flow of the air hole 17, the cleaning block 9 is controlled to slide to the corresponding position, and the blocked air hole 17 is subjected to reverse suction. In this way, the automatic positioning and processing of the blocked part of the air hole 17 are realized, and the normal operation of the dust removal system is ensured.

[0057] When the belt 10 drives the cleaning block 9 to slide to the position corresponding to the miscellaneous cavity 7, at this time, the first toothed plate 29 provided on the cleaning block 9 will be engaged with the rotating gear 38, and the rotating pipe 37 will be rotated through the movement of the cleaning block 9, and the extension pipe 39 will slide towards the direction of the cleaning block 9 through the cooperation of the second spiral groove 40 and the second guide block 41, until the extension pipe 39 is inserted with the positioning ring port 30, and at the same time, when the extension pipe 39 slides, the transmission gear 43 cooperates with the second toothed plate 44 to drive the transmission shaft to drive the blocking ball 42 to rotate, and the hole provided on the blocking ball 42 is consistent with the flow direction of the extension pipe 39, at this time, the inner cavity of the cleaning block 9 will be communicated with the inner cavity of the negative pressure pipe 11, realizing the operation of suction from the bottom of the air hole 17, and further ensuring the flow of the air hole 17.
