Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in processing, specifically a dust removal device for grain processing. Background Technology

[0002] Grain processing refers to the business activities of transforming raw grains into semi-finished or finished grains, or vice versa. Grain processing mainly includes: ① rice milling; ② wheat milling; ③ corn and miscellaneous grain processing; ④ extraction, refining, and processing of vegetable oils; ⑤ production of plant protein products and starch processing; ⑥ processing of grain and oil foods using rice and flour as main raw materials; and ⑦ comprehensive utilization of by-products from grain and oil processing. Currently, grain needs to be transferred to grain depots via unloading machines during production. During unloading, workers must first open the truck doors. Because the trucks are filled with a large amount of grain, grain often spills out when the doors are opened, potentially injuring the workers. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a grain processing dust removal device to solve the technical problem that when the cargo door is opened, the grain will pour out from the cargo door, which may easily injure the workers opening the door.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a grain processing dust removal device, comprising a box fixed on the ground, a fan fixedly connected to the back of the box, and an installation frame fixedly connected to the top of the box. The installation frame has two hollow door blocks with one open side rotatably connected to its interior. A damping rod is provided between the hollow door blocks and the installation frame, and the two ends of the damping rod are rotatably connected to the hollow door blocks and the installation frame, respectively.

[0005] By adopting the above technical solution, the container is firmly fixed on the ground, providing a stable support foundation for the entire device. The fan effectively ensures the operation of the dust removal system, which uses suction to promptly suck in the dust and impurities generated during the unloading process and transport them to the external dust removal device for treatment, thereby significantly improving the working environment and reducing environmental pollution.

[0006] Furthermore, the hollow door stop is provided with a slot, and a locking block is rotatably connected to one side of the mounting frame, with two locking blocks provided.

[0007] By adopting the above technical solution, the slot on the hollow door block and the rotatably connected block on one side of the mounting frame cooperate with each other to form a simple and effective locking mechanism. When the block is engaged in the slot, the hollow door block is firmly locked in the mounting frame and cannot be rotated at will. This ensures that the hollow door block can remain stable when there is no unloading operation and will not be accidentally opened due to external force, thereby improving the safety and stability of the device.

[0008] Furthermore, one end of each of the two locking blocks engages with the slots on the two hollow door blocks respectively, thereby locking the hollow door blocks.

[0009] By adopting the above technical solution, one end of each of the two locking blocks engages with the slots on the two hollow door blocks, thus realizing a simple and reliable locking mechanism. When it is necessary to lock the hollow door block, simply rotate the locking block to the slot position and engage it to securely lock the hollow door block in the mounting frame.

[0010] Furthermore, the bottom of the box is fixedly connected to adjustable height support legs, and multiple support legs are provided, with multiple support legs fixedly connected to the ground.

[0011] By adopting the above technical solution, the adjustable height support legs fixedly connected to the bottom of the container allow the entire device to be flexibly adjusted according to different working environments and ground conditions. By adjusting the height of the support legs, a suitable docking distance can be maintained between the container and the truck door, thus facilitating the smooth unloading of grain.

[0012] Furthermore, the hollow door block is arranged in a fan shape, and the side of the hollow door block facing the truck has an opening for unloading materials.

[0013] By adopting the above technical solution, the hollow door stop is set in a fan-shaped structure, which allows the hollow door stop to better adapt to the opening angle of the truck door when rotating. The fan-shaped structure not only increases the contact area between the hollow door stop and the truck door, improving the sealing performance, but also ensures that the hollow door stop can rotate and open smoothly when the truck door is opened, providing sufficient space for unloading grain.

[0014] Furthermore, a slot for placing the conveyor belt is provided at the bottom of the box, and the fan is connected to an external dust removal device through a pipe.

[0015] By adopting the above technical solution, the empty trough set at the bottom of the box for placing the conveyor belt provides convenience for the installation and use of the conveyor belt. During the unloading process, the conveyor belt can smoothly enter the box through the empty trough and transport the unloaded grain away in a timely manner.

[0016] Furthermore, a foot pedal is fixedly connected to the back of the container, which is used to facilitate the user's entry into the grain transport vehicle.

[0017] By adopting the above technical solution, the foot pedal fixedly connected to the back of the container provides users with a convenient and safe passage, allowing them to easily enter the grain truck. The foot pedal allows workers to enter the grain truck quickly and stably without the need for other tools or equipment, greatly improving work efficiency and operational safety.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model provides a stable foundation for grain unloading operations by setting up an installation frame, hollow door blocks, and damping rods. The installation frame and hollow door blocks ensure that the truck doors can fit tightly against the frame, forming an effective seal to prevent grain from splashing out during unloading. The damping rods control the opening speed of the hollow door blocks, preventing a sudden surge of grain and ensuring a smooth and orderly unloading process. The support legs are adjusted to a suitable height according to the vehicle body requirements, further ensuring the stability of the container and providing reliable support for the unloading operation. The operation of the fan and external dust removal device ensures the normal operation of the dust removal system, contributing to a cleaner working environment. The damping rod effectively controls the opening speed of the hollow door block, preventing sudden spillage of grain and ensuring the safety and stability of the unloading process. As the cargo door gradually opens, the grain inside the truck begins to flow out in an orderly manner, falling into the container through the opening on the hollow door block. This ensures accurate grain entry and avoids spillage and waste. The grain that falls into the container is then transported to a designated location for further processing via a conveyor belt. This achieves rapid and efficient grain transfer, ensures a clean working environment, reduces environmental pollution, and provides strong support for environmental protection in the grain processing process.

[0020] 2. By setting up a step, this utility model provides workers with a stable and convenient passage, enabling them to easily climb the device. This reduces the physical exertion required for workers to climb, alleviates their physical burden, and improves work comfort and efficiency. Workers no longer need to exert themselves to climb or find other climbing tools; they can easily enter the device for operation or maintenance simply by using the step. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Example 1:

[0029] A dust removal device for grain processing, such as Figures 1-4 As shown, the system includes a box 1 fixed to the ground, a fan 2 fixedly connected to the back of the box 1, and a mounting frame 3 fixedly connected to the top of the box 1. The mounting frame 3 has two hollow door blocks 4 with one open side rotating internally. A damping rod 5 is installed between the hollow door blocks 4 and the mounting frame 3, with both ends of the damping rod 5 rotatably connected to the hollow door blocks 4 and the mounting frame 3 respectively. The mounting frame 3 allows the two hollow door blocks 4 to rotate and connect to it in a mirror image, facilitating truck docking and unloading operations. Furthermore, the opening of one side of the hollow door blocks 4 allows the grain to fall orderly into the box 1, preventing spillage and waste. The damping rod 5, connected between the hollow door blocks 4 and the mounting frame 3, effectively controls the rotation speed of the hollow door blocks 4 through its damping effect, allowing the truck doors to open slowly and smoothly, preventing a sudden surge of grain and effectively protecting worker safety and reducing grain loss.

[0030] See Figure 1 , Figure 2 and Figure 3 The hollow door stop 4 has a slot 6, and a locking block 7 is rotatably connected to one side of the mounting frame 3. There are two locking blocks 7, which are respectively locked into the slots 6 of the two hollow door stop 4, forming a double lock to ensure the stable locking of the hollow door stop 4.

[0031] See Figure 1 , Figure 2 and Figure 3One end of each of the two locking blocks 7 engages with the slots 6 on the two hollow door blocks 4 respectively, thereby locking the hollow door blocks 4. The tight fit between the locking blocks 7 and the slots 6 not only provides the locking function, but also strengthens the connection between the hollow door blocks 4 and the mounting frame 3 to a certain extent, making the whole device more stable and durable.

[0032] See Figure 1 , Figure 2 and Figure 3 The bottom of the container 1 is fixedly connected to adjustable height support legs 8. Multiple support legs 8 are provided and fixedly connected to the ground. The multiple support legs 8 enhance the stability and load-bearing capacity of the device. They are evenly distributed at the bottom of the container 1, forming multiple stable support points with the ground, effectively distributing the weight and pressure of the device, improving the stability of the device, and preventing the device from tilting or collapsing due to single-point force, thereby ensuring the safety of workers and the smooth unloading of grain.

[0033] See Figure 1 , Figure 2 and Figure 3 The hollow door block 4 is arranged in a fan shape, and the side of the hollow door block 4 facing the truck has an opening 9 for unloading. The opening 9 on the side of the hollow door block 4 facing the truck allows the grain to fall into the container 1 in an orderly manner through the opening 9 during the unloading process, avoiding the grain from splashing out during the unloading process, thereby improving the cleanliness and efficiency of the unloading operation.

[0034] See Figure 1 , Figure 2 and Figure 3 The box 1 has an empty trough 10 for placing the conveyor belt at the bottom. The blower 2 is connected to the external dust removal device through the pipe 11. The connection between the blower 2 and the external dust removal device through the pipe 11 makes the dust removal system more complete. During the unloading process, the blower 2 can work continuously, sucking in the generated dust and impurities through the pipe 11 and transporting them to the external dust removal device for treatment.

[0035] The implementation principle of this utility model is as follows: First, ensure that the device is correctly installed and fixed on the ground. Adjust the support leg 8 to a suitable height according to the needs of the vehicle body to ensure that the box 1 is stable and stationary, so that the door and the hollow door stop 4 can abut against each other. Start the fan 2 and the external dust removal device to ensure that the dust removal system can operate normally. Place the conveyor belt in the hollow groove 10 below the box 1. Open the truck door and rotate the locking block 7 to disengage it from the locking groove 6 of the hollow door stop 4, releasing the lock on the hollow door stop 4. At this time, the truck door rotates outward under the pressure of the grain, and slowly... The two hollow door blocks 4 are smoothly pushed open. Due to the presence of the damping rod 5, the opening speed of the hollow door blocks 4 is controlled, preventing a large amount of grain from rushing out instantly. As the cargo door gradually opens, the grain inside the truck begins to flow out in an orderly manner, falling into the container 1 through the opening 9 on the hollow door blocks 4. The grain falling into the container 1 is then transported to a designated location for further processing via a conveyor belt. During the unloading process, the blower 2 continues to work, sucking in the generated dust and impurities through the pipe 11 and transporting them to the external dust removal device for treatment, ensuring a clean working environment.

[0036] Example 2:

[0037] See Figure 4 A foot pedal 12 is fixedly connected to the back of the container 1. The foot pedal 12 is used to facilitate the user to enter the grain transport vehicle. The fixed connection of the foot pedal 12 also enhances the stability and durability of the entire device. The foot pedal 12 is firmly connected to the back of the container 1 and can withstand a large weight and pressure, ensuring that there are no safety hazards such as foot pedal loosening or collapse during the use of the vehicle.

[0038] The principle of this utility model is as follows: First, workers can easily climb onto the device via the step 12, which reduces the physical effort required for climbing and improves convenience.
