Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain drying and conveying technology, and in particular to a continuous conveying device for grain drying. Background Technology
[0002] In the grain processing industry, drying is a key step in ensuring the quality of stored grain, and the continuous conveying device, as an important piece of equipment connecting the pre-processing and drying of grain, directly affects the overall processing progress in terms of its operating efficiency.
[0003] Traditional grain conveying devices mostly have only a single conveying function. Grain needs to be pre-treated separately before entering the drying equipment, which not only increases equipment investment costs but also extends the processing cycle. Furthermore, some conveying devices have unreasonable feeding structure designs, making them prone to jamming due to high grain moisture content or grain sticking, leading to production interruptions and affecting the efficiency of continuous operation. In addition, existing conveying devices lack effective anti-clogging mechanisms during the conveying process, especially in critical areas such as the discharge port, where grain accumulation often causes blockages, requiring frequent manual cleaning, increasing labor costs and posing safety hazards. Therefore, there is an urgent need for a continuous conveying device for grain drying to solve these problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a continuous conveying device for grain drying. Its advantages include: continuous grain conveying; preheating and drying function to improve subsequent drying efficiency; and effective prevention of material blockage through a stirring component, ensuring smooth conveying and reducing processing costs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A continuous conveying device for grain drying includes a feeding hopper and a hopper frame for fixing the feeding hopper. A first inclined plate is fixedly connected to one side of the hopper frame, and a motor is fixedly connected to the outer wall of one side of the first inclined plate. A rotating rod is fixedly connected to the output end of the motor. A feeding cylinder is fixedly connected to one side of the hopper frame, and the other end of the rotating rod is rotatably connected to the inner wall of one side of the feeding cylinder. Spiral blades for conveying grain are fixedly connected to the outer circumference of the rotating rod.
[0007] A discharge pipe is fixedly connected to the bottom outer wall of the feeding hopper, and one end of the discharge pipe is connected to the feeding cylinder;
[0008] The other end of the feeding cylinder is fixedly connected to the discharge cylinder;
[0009] The feed pipe is equipped with a stirring component to prevent the grain from accumulating and clogging.
[0010] A preheating component for drying grain is provided on one side of the feeding hopper.
[0011] The above technical solutions enable continuous grain conveying. Meanwhile, the stirring components inside the feeding pipe can agitate the falling grain to prevent blockages, and the preheating components can perform preliminary drying of the grain during the conveying process, thereby improving the subsequent drying efficiency.
[0012] Preferably, a support frame is fixedly connected to one side of the hopper frame, and a second inclined plate for secondary fixing of the feeding cylinder and a horizontal plate for fixed installation of the preheating component are distributed and fixedly connected to one side of the support frame.
[0013] The above technical solutions enhance the stability of the feeding cylinder during operation, preventing positional shifts caused by vibration. Meanwhile, the horizontal plate provides a stable mounting platform for the hot air blower in the preheating assembly, ensuring stable operation of the preheating assembly.
[0014] Preferably, the preheating assembly includes a hot air blower fixedly connected to the outer wall of the top of the horizontal plate, an air inlet pipe is provided on the top of the hot air blower, and an air guide pipe is provided on the other side of the hot air blower, with the end of the air guide pipe away from the hot air blower connected to the feeding cylinder.
[0015] The above technical solution involves a hot air blower that draws in outside air through an air inlet pipe, heats it to produce hot air, and then transports the hot air through a duct to the inside of the feeding cylinder. This hot air comes into full contact with the grain being transported in the feeding cylinder, preheating and drying the grain, removing some of the moisture, reducing the workload of subsequent drying equipment, and improving overall drying efficiency.
[0016] Preferably, the outer circumferential wall of the feeding cylinder is provided with vent holes, which are distributed in a circular pattern at equal intervals on the outer circumferential wall of the feeding cylinder.
[0017] The above technical solution allows for timely discharge of humid and hot air through vents on the outer circumference of the feeding cylinder, preventing the accumulation of such air inside the cylinder and thus preventing the grain from deteriorating or sticking together due to the influence of humid and hot air, thereby ensuring the quality of the grain during the transportation process.
[0018] Preferably, the stirring assembly includes a fixed block fixedly connected to the outer circumference of the rotating rod, a connecting rod fixedly connected to the outer circumference of the fixed block, and a lifting column rotatably connected to one end of the connecting rod.
[0019] Through the above technical solution: because the connecting rod is rotatably connected to the lifting column, the lifting column can also move up and down while rotating with the rotating rod, thereby agitating the grain in the feeding pipe and preventing the grain from accumulating.
[0020] Preferably, a rotating seat is fixedly connected to the inner circumference of the feeding pipe, and one end of the lifting column passes through the inside of the rotating seat.
[0021] The above technical solutions ensure that the lifting column maintains a stable trajectory during its up-and-down movement and rotation, preventing it from colliding with the inner wall of the discharge pipe due to shaking, and guaranteeing the normal operation of the mixing components.
[0022] Preferably, the outer circumferential wall of the lifting column is fixedly connected with a diagonal rod, and the diagonal rod is distributed in a circular pattern at equal intervals on the outer circumferential wall of the lifting column.
[0023] Through the above technical solution: when the lifting column moves, the inclined rod on its outer circumference moves along with it. The inclined rod can increase the contact area with the grain, more effectively agitate the grain in the feeding pipe, and further prevent the grain from accumulating and blocking due to high humidity and particle sticking, thus ensuring smooth feeding.
[0024] The beneficial effects of this utility model are as follows:
[0025] 1. A continuous conveying device for grain drying, which drives the rotating rod and spiral blades to rotate by a motor, and works in conjunction with the synergistic effect of the feeding hopper, the feeding pipe, the feeding cylinder and the unloading cylinder to achieve continuous and stable conveying of grain, avoiding the conveying jamming problem caused by unreasonable structural design in traditional conveying process, ensuring continuous operation of grain processing, and effectively improving the overall processing progress.
[0026] 2. A continuous conveying device for grain drying, which is equipped with a preheating component to enable the device to pre-dry. The hot air generated by the hot air blower enters the feeding cylinder through the air guide pipe and fully contacts the grain, which can remove some moisture and timely discharge the hot and humid air through the exhaust hole to avoid moisture accumulation affecting the drying effect. This design reduces the load on the subsequent drying equipment, improves the drying efficiency, and reduces energy consumption, which helps to ensure the quality of the grain after drying.
[0027] 3. A continuous conveying device for grain drying, wherein the stirring component inside the feeding pipe drives the fixed block and connecting rod through the rotating rod to make the lifting column rise and rotate in the rotating seat, and at the same time the inclined rod on its outer circumference can effectively stir the grain, effectively solving the problem of blockage caused by grain accumulation at the feeding port, eliminating the need for frequent manual cleaning, reducing labor costs, eliminating the safety hazards caused by manual cleaning, and further ensuring the smooth operation of the device.

[0037] Reference Figures 1-4A continuous conveying device for grain drying includes a feeding hopper 1 and a hopper frame 3 for fixing the feeding hopper 1. A first inclined plate 4 is fixedly connected to one side of the hopper frame 3. A motor 5 is fixedly connected to the outer wall of one side of the first inclined plate 4. A rotating rod 15 is fixedly connected to the output end of the motor 5. A feeding cylinder 6 is fixedly connected to one side of the hopper frame 3. The other end of the rotating rod 15 is rotatably connected to the inner wall of one side of the feeding cylinder 6. A spiral blade 16 for conveying grain is fixedly connected to the outer circumference of the rotating rod 15.
[0038] The bottom outer wall of the feeding hopper 1 is fixedly connected to the discharge pipe 2, and one end of the discharge pipe 2 is connected to the feeding cylinder 6;
[0039] The other end of the feeding cylinder 6 is fixedly connected to the unloading cylinder 7;
[0040] The inside of the feeding pipe 2 is equipped with a stirring component to prevent the grain from accumulating and clogging.
[0041] A preheating component for drying grain is provided on one side of the feeding hopper 1. When the motor 5 starts, its output end drives the rotating rod 15 to rotate inside the feeding cylinder 6. The spiral blades 16 on the rotating rod 15 rotate accordingly, which can continuously push the grain entering the feeding cylinder 6 from the discharge pipe 2 forward and finally discharge it through the discharge cylinder 7, realizing continuous grain conveying. At the same time, the stirring component in the discharge pipe 2 can stir the falling grain to avoid blockage. The preheating component can perform preliminary drying of the grain during the conveying process, improving the subsequent drying efficiency.
[0042] Furthermore, a support frame 14 is fixedly connected to one side of the hopper frame 3. A second inclined plate 13 for secondary fixation of the feeding cylinder 6 and a horizontal plate 12 for fixed installation of the preheating component are distributed and fixedly connected to one side of the support frame 14. The support frame 14 provides a stable support foundation for the device. The second inclined plate 13 cooperates with the hopper frame 3 to fix the feeding cylinder 6 from both sides, which enhances the stability of the feeding cylinder 6 during operation and avoids position displacement due to vibration. At the same time, the horizontal plate 12 provides a stable installation platform for the hot air blower 9 in the preheating component, ensuring that the preheating component can work stably.
[0043] Furthermore, the preheating component includes a hot air blower 9 fixedly connected to the top outer wall of the horizontal plate 12. The top of the hot air blower 9 is provided with an air inlet pipe 8, and the other side of the hot air blower 9 is provided with an air guide pipe 10. The end of the air guide pipe 10 away from the hot air blower 9 is connected to the feeding cylinder 6. The hot air blower 9 draws in outside air through the air inlet pipe 8, generates hot air after heating, and is transported to the inside of the feeding cylinder 6 through the air guide pipe 10. It comes into full contact with the grain conveyed in the feeding cylinder 6, preheats and dries the grain, removes some moisture, reduces the workload of subsequent drying equipment, and improves the overall drying efficiency.
[0044] Furthermore, the outer circumferential wall of the feeding cylinder 6 is provided with exhaust holes 11. The exhaust holes 11 are distributed in a circular pattern at equal intervals on the outer circumferential wall of the feeding cylinder 6. The hot and humid air generated after the hot air comes into contact with the grain can be discharged in time through the exhaust holes 11 on the outer circumferential wall of the feeding cylinder 6, so as to avoid the accumulation of hot and humid air in the feeding cylinder 6, prevent the grain from deteriorating or sticking due to the influence of hot and humid air, and ensure the quality of the grain during the conveying process.
[0045] Furthermore, the mixing assembly includes a fixed block 21 fixedly connected to the outer circumference of the rotating rod 15. A connecting rod 20 is fixedly connected to the outer circumference of the fixed block 21. One end of the connecting rod 20 is rotatably connected to a lifting column 17. When the rotating rod 15 rotates, it drives the fixed block 21 to rotate synchronously. The fixed block 21 drives the lifting column 17 to move through the connecting rod 20. Since the connecting rod 20 and the lifting column 17 are rotatably connected, the lifting column 17 can also move up and down while rotating with the rotating rod 15, thereby agitating the grain in the feed pipe 2 and preventing the grain from accumulating.
[0046] Furthermore, a rotating seat 18 is fixedly connected to the inner circumference of the feeding pipe 2. One end of the lifting column 17 passes through the inside of the rotating seat 18. The rotating seat 18 provides support and limit for the lifting column 17, ensuring that the lifting column 17 maintains a stable movement trajectory during the up-and-down lifting and rotation process, avoiding collision between the lifting column 17 and the inner wall of the feeding pipe 2 due to shaking, and ensuring the normal operation of the mixing component.
[0047] Furthermore, a diagonal rod 19 is fixedly connected to the outer circumference of the lifting column 17. The diagonal rods 19 are distributed in a circular pattern at equal intervals on the outer circumference of the lifting column 17. When the lifting column 17 moves, the diagonal rods 19 on its outer circumference move together with it. The diagonal rods 19 can increase the contact area with the grain, more effectively agitate the grain in the feeding pipe 2, and further prevent the grain from accumulating and blocking due to high humidity and particle sticking, thus ensuring smooth feeding.
[0048] Working Principle: During operation, grain enters from the hopper 1 and is conveyed to the feeding cylinder 6 via the discharge pipe 2. The motor 5 drives the rotating rod 15 to rotate, which in turn drives the spiral blades 16 to rotate, achieving continuous conveying of the grain within the feeding cylinder 6. Finally, the grain is discharged through the discharge cylinder 7. During the conveying process, the hot air blower 9 in the preheating component draws in air through the air inlet pipe 8 and heats it. The hot air enters the feeding cylinder 6 through the air guide pipe 10, making full contact with the flowing grain to achieve pre-drying treatment. The humid and hot air is discharged through the exhaust hole 11 on the outer wall of the feeding cylinder 6, preventing moisture accumulation from affecting the drying effect, improving the efficiency of subsequent drying treatment, and reducing the overall processing time. At the same time, when the rotating rod 15 rotates, the fixed block 21 on its outer circumference drives the connecting rod 20 to move, causing the lifting column 17 to move up and down and rotate within the rotating seat 18. The inclined rod 19 on the lifting column 17 stirs the grain in the discharge pipe 2, effectively preventing grain accumulation and blockage, and ensuring smooth feeding.
[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
