Description

Technical Field

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

[0002] With the advancement of agricultural modernization, the grain processing industry is developing day by day, and the transportation of grain has become an important link in the grain processing process. Among them, grain transportation equipment is an indispensable and important tool in the grain processing process. They are mainly used to transfer grain from one place to another efficiently and safely. Traditional grain transportation devices often lack effective dust removal methods, which produces a lot of dust during the transportation process, which not only pollutes the environment but also threatens human health. In recent years, the industry has begun to pay attention to this issue and has successively developed some grain transportation devices with dust removal functions. These devices have reduced dust pollution during the transportation process to a certain extent.

[0003] At present, although some existing grain processing and transportation devices have certain dust removal functions, they generally have problems such as poor dust removal effect, complex equipment, and high cost. Especially when processing a large amount of grain, the dust removal effect is even less ideal, resulting in environmental pollution and waste of resources.

[0004] For example, the Chinese invention patent with authorization announcement number CN113772451B provides a dust-removing grain transfer device. Although the dust can be adsorbed by the dust removal device, the dust removal device can only adsorb the dust floating in the air, but cannot adsorb the dust that falls on the conveyor belt and mixed in the grain pile. Therefore, the transferred grain still contains a large amount of dust, and dust removal is still required after being transferred to different processing equipment, which greatly increases the grain processing cost. Summary of the invention

[0005] The purpose of the present invention is to provide a grain processing and transfer device with a dust removal function, which not only has high dust removal efficiency but also good dust removal effect. At the same time, a dust suction control mechanism is arranged in each dust suction port to scatter the grain on the transfer conveyor belt, ensuring that the dust suction port can effectively absorb the dust mixed in the grain, so that the grain does not need to be dusted again after transfer, which greatly reduces the cost of grain processing.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A food processing and transfer device with a dust removal function comprises a frame and a transfer conveyor belt cyclically rotated on the frame, and also comprises a dust removal mechanism, wherein the dust removal mechanism comprises a sealing cover body fixedly connected to the frame, the transfer conveyor belt is located in the sealing cover body, a feeding port is provided on the side of the sealing cover body opposite to the conveying starting end of the transfer conveyor belt, a discharge port is provided on the side below the sealing cover body opposite to the conveying end of the transfer conveyor belt, a partition is provided between the upper surface of the transfer conveyor belt and the top of the sealing cover body, the partition and the top wall and side wall of the sealing cover body form a dust suction chamber, the dust suction chamber is provided with an exhaust port connected to a dust collector, a plurality of dust suction ports are provided on the partition, and a dust suction control mechanism is provided in each dust suction port.

[0008] By adopting the above technical solution, a sealed cover is set on the transfer conveyor belt, which can effectively curb the diffusion of dust during the transportation process and ensure the dust removal effect. The dust suction chamber cleverly set in the sealed cover, combined with the multiple dust suction ports on the partition, constructs a multi-point dust suction network above the transfer conveyor belt to fully absorb dust, which not only improves the dust suction efficiency but also optimizes the dust suction effect. In addition, the dust suction control mechanism built into the dust suction port can also effectively disperse the grain on the transfer conveyor belt, ensuring that the dust suction port can penetrate into the grain and fully absorb the dust mixed in it, thereby realizing the dust removal-free treatment of the grain after transfer, greatly reducing the cost of grain processing.

[0009] The present invention is further configured as follows: the dust suction port is circular, the dust suction control mechanism includes a sphere matching the diameter of the dust suction port, the top of the sphere is connected to the top wall of the sealing cover body through a spring, and the bottom of the sphere is connected to the material dispensing mechanism.

[0010] By adopting the above technical solution, the sphere overcomes the spring force under the action of its own gravity and falls into the dust suction port to block the dust suction port. When the dust collector exhausts air into the dust suction chamber through the exhaust port, negative pressure is gradually formed in the dust suction chamber. As the negative pressure in the dust suction chamber continues to increase, the sphere gradually moves upward until the dust suction port is opened. When the dust suction port is opened, the dust below the dust suction port and above the transfer conveyor belt and between the grain particles on the transfer conveyor belt are quickly sucked in, ensuring the cleanliness of the grain during transportation. After the dust is sucked into the dust suction chamber along with the air, the negative pressure in the dust suction chamber is instantly reduced, and the sphere falls again under the action of its own gravity to close the dust suction port. The dust collector continues to exhaust air, and the negative pressure in the dust suction chamber increases again, causing the sphere to fall again. The upward movement opens the dust suction port, and this process is repeated to form an intermittent dust suction effect. While the sphere moves up and down, it drives the material-dispensing mechanism to continuously disperse the grain on the transfer conveyor belt, so that the dust inside the grain on the transfer conveyor belt is fully exposed and fully adsorbed. Therefore, the negative pressure of the dust suction chamber not only drives the sphere to achieve intermittent movement to form a dynamic balance and ensure the dust removal effect, but also drives the material-dispensing mechanism to repeatedly dispense materials, thereby achieving efficient cleaning during the grain transfer process. At the same time, due to the intermittent blocking and opening of the sphere, the dust removal efficiency of the dust suction chamber is optimized. In addition, the structure is simple and easy to maintain, and will not cause any damage to the grain itself, further improving the quality and efficiency of grain processing.

[0011] The present invention is further configured as follows: the material shifting mechanism includes a connecting rod fixed at the bottom of the sphere, and a shifting rod 1 and a shifting rod 2 are symmetrically provided on both sides of the connecting rod, the upper ends of the shifting rod 1 and the shifting rod 2 are respectively rotatably connected to the bottom of the connecting rod through waist-shaped long holes, and the lower ends of the shifting rod 1 and the shifting rod 2 are respectively provided with a toothed shifting plate 1 and a toothed shifting plate 2, and the middle parts of the shifting rod 1 and the shifting rod 2 are respectively connected to the partition through a driving rod 1 and a driving rod 2.

[0012] By adopting the above technical solution, the connecting rod moves up and down with the ball, and the lower ends of the lever 1 and the lever 2 are driven by the driving rod 1 and the driving rod 2 to make an arc movement towards or away from each other. During the movement, the lever 1 and the lever 2 drive the toothed plate 1 and the toothed plate 2 to reciprocate the grain on the transfer conveyor belt, so that the dust in the grain on the transfer conveyor belt is fully exposed, so that the dust in the grain can be better absorbed by the dust suction port, thereby achieving the purpose of improving the dust removal effect of the grain.

[0013] The present invention is further configured as follows: the toothed plate 1 and the toothed plate 2 are both located between the lever 1 and the lever 2, the toothed plate 1 and the toothed plate 2 are both slidably matched with a guide rod parallel to the conveying surface of the transfer conveyor belt, the toothed plate 1 and the toothed plate 2 are connected by a spring 2, and the two ends of the guide rod are respectively fixedly connected to the side walls on both sides of the sealing cover body.

[0014] By adopting the above technical scheme, the toothed paddle plate 1 and the toothed paddle plate 2 are connected by the spring 2, so that when the paddle rod 1 and the paddle rod 2 are approaching or moving away from each other, the toothed paddle plate 1 and the toothed paddle plate 2 can slide back and forth along the guide rod toward or in the opposite direction. The toothed paddle plate 1 and the toothed paddle plate 2 repeatedly poke the grain on the transfer conveyor belt during the sliding toward or in the opposite direction, and the toothed paddle plate 1 and the toothed paddle plate 2 can fully cover the width of the transfer conveyor belt under the action of the spring 2, thereby fully ensuring the material shifting effect. In addition, when the toothed paddle plate 1 and the toothed paddle plate 2 are in motion, the grain is effectively turned over during the transportation process through the sliding cooperation with the guide rod. On the one hand, the grain is evenly distributed on the transfer conveyor belt, effectively avoiding the accumulation and slipping of grain during the transportation process, further improving the reliability of the transfer and transportation, and on the other hand, the grain is more easily exposed to dust when being shifted, thereby improving the dust suction effect and improving the dust removal efficiency.

[0015] The present invention is further configured as follows: the dust suction ports are evenly distributed on the partition, and the dust suction ports are staggered with each other.

[0016] By adopting the above technical solution, the dust suction ports are staggered to form a high-efficiency adsorption network above the transfer conveyor belt, which not only significantly expands the coverage area of ​​the adsorption point, but also ensures that the dynamic movement of the sphere in the suction port and the synergy between the material dispensing mechanisms will not interfere with each other, thereby ensuring the continuous and stable operation of the entire dust removal system.

[0017] The present invention is further configured as follows: when the sphere moves up and down, it drives the lower end of the connecting rod to contact or separate from the upper surface of the transfer conveyor belt.

[0018] By adopting the above technical solution, the grain on the transfer conveyor belt can be effectively disturbed during the contact or separation between the lower end of the connecting rod and the upper surface of the transfer conveyor belt, causing dust to easily escape from between the grain particles, thereby significantly improving the dust removal efficiency. At the same time, the ingenious linkage between the sphere and the connecting rod not only reduces energy consumption, but also greatly improves the operating efficiency of the entire dust removal system.

[0019] The present invention is further configured as follows: the first toothed shift plate and the second toothed shift plate are both made of rubber.

[0020] By adopting the above technical solution, the rubber material is softer in texture, which can greatly reduce the wear on the transfer conveyor belt, while ensuring the safety of the conveyor belt and the grain, extending the service life of the equipment, and ensuring the quality of the grain. In addition, the rubber material is low in cost, easy to process, and more economical. At the same time, because the rubber material of the toothed paddle plate 1 and the toothed paddle plate 2 has good elasticity, in the process of shifting the grain, it can better adapt to the vibration of the transfer conveyor belt, maintain stable contact, and have a better material shifting effect, which indirectly improves the dust collection efficiency.

[0021] The present invention is further configured as follows: the transfer conveyor belt is tensioned and driven by conveyor roller one and conveyor roller two, the conveyor roller one and conveyor roller two are respectively rotatably connected to the sealing cover body, one end of the conveyor roller one or conveyor roller two is fixedly connected to the output shaft of the driving motor fixed on the sealing cover body, and the surfaces of the conveyor roller one and conveyor roller two are provided with anti-slip stripes.

[0022] By adopting the above technical scheme, the driving motor drives the conveyor roller one or the conveyor roller two connected thereto to rotate. When the conveyor roller one or the conveyor roller two rotates, it drives the transfer conveyor belt to rotate circularly. During the circular rotation of the transfer conveyor belt, the grain is transported and transferred. The structure is simple and the operation is convenient, making the equipment more stable and reliable during operation. The anti-slip stripes on the surface of the conveyor roller one and the conveyor roller two can effectively enhance the friction with the transfer conveyor belt, thereby ensuring the stability of the conveying process and effectively ensuring the efficiency of grain transfer and transportation.

[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention can effectively curb the diffusion of dust during the transportation process and ensure the dust removal effect by arranging a sealing cover on the transfer conveyor belt. The dust suction chamber cleverly arranged in the sealing cover cooperates with the multiple dust suction ports on the partition to construct a multi-point dust suction network above the transfer conveyor belt to fully absorb the dust, which not only improves the dust suction efficiency but also optimizes the dust suction effect. In addition, the dust suction control mechanism built into the dust suction port can also effectively disperse the grain on the transfer conveyor belt, ensuring that the dust suction port can penetrate into the grain and fully absorb the dust mixed therein, thereby realizing the dust-free treatment of the grain after transportation, greatly reducing the grain processing cost.

[0025] 2. The dust suction control mechanism of the present invention drives the material-discharging mechanism to continuously disperse the grains on the transfer conveyor belt while the ball moves up and down, so that the dust inside the grains on the transfer conveyor belt is fully exposed and fully adsorbed. Therefore, the negative pressure of the dust suction chamber not only drives the ball to achieve intermittent movement and form a dynamic balance to ensure the dust removal effect, but also drives the material-discharging mechanism to repeatedly disperse the material, thereby achieving efficient cleaning during the grain transfer process. At the same time, due to the intermittent blocking and opening of the ball, the dust removal efficiency of the dust suction chamber is optimized, and the structure is simple and easy to maintain, and will not cause any damage to the grain itself, further improving the quality and efficiency of grain processing.

[0026] 3. The toothed paddle plate 1 and the toothed paddle plate 2 in the material-pickup mechanism of the present invention are connected by a spring 2, so that when the paddle rod 1 and the paddle rod 2 are approaching or moving away from each other, the toothed paddle plate 1 and the toothed paddle plate 2 can slide back and forth along the guide rod toward or in the opposite direction. The toothed paddle plate 1 and the toothed paddle plate 2 repeatedly poke the grain on the transfer conveyor belt during the process of sliding toward or in the opposite direction, and the toothed paddle plate 1 and the toothed paddle plate 2 can fully cover the width of the transfer conveyor belt under the action of the spring 2, thereby fully ensuring the material-pickup effect. In addition, when the toothed paddle plate 1 and the toothed paddle plate 2 are in motion, the grain is effectively turned over during the transportation process through the sliding cooperation with the guide rod. On the one hand, the grain is evenly distributed on the transfer conveyor belt, effectively avoiding local accumulation and slipping of the grain during the transportation process, further improving the reliability of the transportation and transportation, and on the other hand, the grain is more easily exposed to dust when being pried, thereby improving the dust suction effect and improving the dust removal efficiency.

[0027] 4. The dust suction ports on the partitions of the present invention are staggered to form a highly efficient adsorption network above the transfer conveyor belt, which not only makes the adsorption point coverage area larger, but also the dynamic movement of the sphere in the adsorption port and the coordinated action of the material-dispensing mechanism will not interfere with each other, thus ensuring the continuous and stable operation of the entire dust removal system.

[0028] 5. In the present invention, the toothed paddle plate 1 and the toothed paddle plate 2 are both made of rubber material, which is relatively soft and can greatly reduce the wear on the transfer conveyor belt, and will not cause damage to the transfer conveyor belt and grain, which is beneficial to improving the service life of the equipment and ensuring the quality of grain. In addition, the rubber material is low in cost and easy to process. At the same time, since the rubber material of the toothed paddle plate 1 and the toothed paddle plate 2 has good elasticity, in the process of prying grain, it can better adapt to the vibration of the transfer conveyor belt, maintain stable contact, and have a better material prying effect, which indirectly improves the dust collection efficiency.

[0037] Furthermore, the dust suction port 36 is circular, and the dust suction control mechanism 4 includes a sphere 41 that matches the diameter of the dust suction port 36 , the top of the sphere 41 is connected to the top wall of the sealing cover body 31 through a spring 42 , and the bottom of the sphere 41 is connected to the material dispensing mechanism 5 .

[0038] Furthermore, the material shifting mechanism 5 includes a connecting rod 51 fixed to the bottom of the sphere 41, and a shifting rod 1 52 and a shifting rod 2 53 are symmetrically provided on both sides of the connecting rod 51, and the upper ends of the shifting rod 1 52 and the shifting rod 2 53 are rotatably connected to the bottom of the connecting rod 51 through waist-shaped long holes, and the lower ends of the shifting rod 1 52 and the shifting rod 2 53 are respectively provided with a toothed shifting plate 1 54 and a toothed shifting plate 2 55, and the middle parts of the shifting rod 1 52 and the shifting rod 2 53 are respectively connected to the partition 37 through a driving rod 1 56 and a driving rod 2 57.

[0039] Furthermore, the toothed plate 1 54 and the toothed plate 2 55 are both located between the lever 1 52 and the lever 2 53, and the toothed plate 1 54 and the toothed plate 2 55 are both slidably matched with the guide rod 58 parallel to the conveying surface of the transfer conveyor belt 2, and the toothed plate 1 54 and the toothed plate 2 55 are connected by a spring 2 59, and the two ends of the guide rod 58 are respectively fixedly connected to the side walls on both sides of the sealing cover body 31.

[0040] Further, such as Figure 4 As shown, the dust suction ports 36 are evenly distributed on the partition 37, and the dust suction ports 36 are staggered with each other.

[0041] Furthermore, when the sphere 41 moves up and down, it drives the lower end of the connecting rod 51 to contact or separate from the upper surface of the transfer conveyor belt 2.

[0042] Furthermore, the toothed shift plate 1 54 and the toothed shift plate 2 55 are both made of rubber.

[0043] Furthermore, the transfer conveyor belt 2 is tensioned and driven by conveyor roller 1 6 and conveyor roller 2 7, and the conveyor roller 1 6 and conveyor roller 2 7 are respectively rotatably connected to the sealing cover body 31, and one end of the conveyor roller 1 6 or conveyor roller 2 7 is fixedly connected to the output shaft of the driving motor 8 fixed on the sealing cover body 31.

[0044] The working principle of the present invention is as follows: the grain to be transported enters the sealed cover body 31 from the feed port 32 on one side of the sealed cover body 31 and falls on the upper surface of the transport conveyor belt 2 in the sealed cover body 31, and the driving motor 8 drives the conveyor roller 1 6 or the conveyor roller 2 7 connected thereto to rotate, and the conveyor roller 1 6 or the conveyor roller 2 7 drives the transport conveyor belt 2 to rotate cyclically when the conveyor roller 1 6 or the conveyor roller 2 7 rotates, and the grain is transported and transported during the cyclic rotation of the transport conveyor belt 2 and discharged from the discharge port 33;

[0045] When the driving motor 8 is started, the dust collector is also started. When the dust collector exhausts the dust suction chamber 34 through the exhaust port 35, a negative pressure is gradually formed in the dust suction chamber 34. As the negative pressure in the dust suction chamber 34 continues to increase, the ball 41 gradually moves upward until the dust suction port 36 is opened. When the dust suction port 36 is opened, the dust below the dust suction port 36 and above the transfer conveyor belt 2 and between the grain particles on the transfer conveyor belt 2 are quickly sucked in, ensuring the cleanliness of the grain during the transportation process. After the dust is sucked into the dust suction chamber 34 along with the air, the negative pressure in the dust suction chamber 34 is instantly reduced, and the ball 41 falls again under the action of its own gravity to close the dust suction port 36. The dust collector continues to exhaust, and the negative pressure in the dust suction chamber 34 increases again, causing the ball 41 to move upward again to open the dust suction port 36, and this is repeated to form an intermittent dust suction effect.

[0046] During the up and down movement, the sphere 41 drives the material shifting mechanism 5 to continuously shift the grains on the transfer conveyor belt 2, so that the dust inside the grains on the transfer conveyor belt 2 is fully exposed and fully absorbed, that is, during the up and down movement of the sphere 41, the connecting rod 51 is driven to move up and down, and during the up and down movement of the connecting rod 51, the lower ends of the shifting rods 1 52 and 2 53 are driven to move in an arc shape toward or away from each other through the driving rods 1 56 and 2 57 respectively, and the shifting rods 1 52 and 2 53 drive the toothed shifting plates 1 54 and 2 55 to shift the grains on the transfer conveyor belt 2 back and forth during the movement, so that the dust in the grains on the transfer conveyor belt 2 is fully exposed, so that the dust in the grains can be better absorbed by the dust suction port 36, thereby achieving the purpose of improving the dust removal effect of the grains.
