Description

Technical Field

[0001] This utility model relates to the field of grain feeding and conveying technology, specifically a grain feeding and conveying device for grain sales. Background Technology

[0002] Grain conveying systems are mechanical devices used in the agricultural and food processing industries. They are designed to efficiently and safely transport granular materials such as grains. These devices play an important role in modern agriculture and food processing plants, significantly improving work efficiency, reducing labor costs, and ensuring that material losses are minimized during transport.

[0003] Screw conveyors are a common type of conveying device. They use rotating helical blades to push materials along pipes. This equipment can conveniently transport grains to designated locations. However, in actual use, some grains are quite wet. When grains are wet, they are more likely to adhere to the helical blades and the inner wall of the pipe, causing poor material flow or even complete blockage. This not only reduces conveying efficiency but may also require shutdown for cleaning, increasing maintenance costs and time. Utility Model Content

Through the integration of mechanical conveying, rotary drying and intelligent control, it realizes efficient conveying and pre-drying of wet grains. It not only solves the problems of easy clogging and uneven drying of traditional screw conveyors when processing wet grains, but also improves the overall automation level and energy efficiency of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grain feeding and conveying device, comprising a feeding pipe inclined from left to right, wherein support frames are fixedly connected to the front and rear surfaces of both ends of the feeding pipe, and the bottoms of the four support frames are located on the same horizontal plane.

[0006] A feeding hopper is fixedly connected to the top left end of the feeding pipe, and a feeding pipe is fixedly connected to the bottom right end of the feeding pipe. A feeding auger is rotatably connected inside the feeding pipe and is inclined to the left and right. The feeding auger is parallel to the feeding pipe. A drying sleeve is rotatably connected to the outer surface of the feeding pipe. The drying sleeve is parallel to the feeding pipe and the feeding auger. At least four horizontal pipes are fixedly connected to the surface of the drying sleeve in a circumferential array. Multiple nozzles are fixedly connected to the four horizontal pipes near the side of the drying sleeve. The ends of the multiple nozzles away from the horizontal pipes extend into the interior of the drying sleeve and are fixedly connected thereto. Multiple air holes are opened in a circumferential array on the inner surface of the feeding pipe located in the drying sleeve.

[0007] As a preferred embodiment of the grain feeding and conveying device of this utility model, a rotating rod is fixedly connected to the inner wall of the feeding auger, which is arranged with the left side lower than the right side. The rotating rod is arranged parallel to the feeding pipe, the feeding auger and the drying sleeve. A controller is fixedly connected to the surface of the support frame at the front left end.

[0008] In a preferred embodiment of the grain sales feeding and conveying device of this utility model, the right end of the rotating rod is rotatably connected to the right side of the inner wall of the feeding pipe, the left end of the rotating rod extends to the left side of the outer wall of the feeding pipe and is rotatably connected thereto, and a first motor is fixedly connected to the left side of the outer wall of the feeding pipe.

[0009] As a preferred embodiment of the grain sales feeding and conveying device of this utility model, the output shaft of the first motor is fixedly connected to the left end of the rotating rod, a protective cover is provided outside the first motor, and one side of the protective cover is fixedly connected to the outer wall of the left side of the feeding pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, grains enter the feeding pipe through the feeding hopper. The feeding auger is driven by the first motor to rotate and push the grains from left to right. The second motor starts and drives the drive gear to rotate. The drive gear drives the driven gear and the entire drying sleeve to rotate through meshing transmission. The drying sleeve rotates around the feeding pipe, so that the position of the nozzle changes continuously, forming dynamic drying. This dynamic heating method makes the hot air distribution more uniform and avoids the problems of local overheating or uneven drying. The limit ring ensures that the drying sleeve rotates smoothly and prevents eccentricity or shaking from affecting the sealing performance.

The hot air in the horizontal pipe is sprayed into the interior of the drying jacket through multiple nozzles. All the horizontal pipes are interconnected through connecting pipes to form a complete hot air circulation. The hot air is evenly distributed in the drying jacket and transfers heat to the grain inside through the air holes on the wall of the feeding pipe. The hot air penetrates into the interior of the feeding pipe and directly contacts the grain, improving the drying efficiency. The grain that has been conveyed and dynamically dried reaches the right end of the feeding pipe and is discharged through the discharge pipe to enter the subsequent processing stage.

Detailed Implementation

[0020] Please see Figures 1-3 A grain feeding and conveying device includes a feeding pipe 1 that is inclined from left to right, with support frames 2 fixedly connected to the front and rear surfaces of both ends of the feeding pipe 1. The bottoms of the four support frames 2 are located on the same horizontal plane.

[0021] Furthermore, a feeding hopper 3 is fixedly connected to the top left end of the feeding pipe 1, and a feeding pipe 4 is fixedly connected to the bottom right end of the feeding pipe 1. A feeding auger 5, which is inclined to the left and high, is rotatably connected inside the feeding pipe 1. The feeding auger 5 is parallel to the feeding pipe 1. A drying sleeve 8 is rotatably connected to the outer surface of the feeding pipe 1. The drying sleeve 8 is parallel to the feeding pipe 1 and the feeding auger 5. At least four horizontal pipes 9 are fixedly connected to the surface of the drying sleeve 8 in a circumferential array. Multiple nozzles 10 are fixedly connected to the four horizontal pipes 9 near the side of the drying sleeve 8. The ends of the multiple nozzles 10 away from the horizontal pipes 9 extend into the interior of the drying sleeve 8 and are fixedly connected thereto. Multiple air holes 101 are opened in a circumferential array on the inner surface of the feeding pipe 1 located in the drying sleeve 8.

[0022] The feeding pipe 1 is inclined from left to right, and contains a feeding auger 5 to actively transport grain from left to right. Four support frames 2 are installed at the left and right ends of the feeding pipe 1, one at the front and one at the back, ensuring the entire machine is stably installed on the ground with its bottom on the same horizontal plane for smooth operation. The feed hopper 3 is fixedly connected to the top left end of the feeding pipe 1, serving as the inlet for the grain. The discharge pipe 4 is located at the bottom right end of the feeding pipe 1, discharging the partially dried grain to subsequent equipment or storage containers. The feeding auger 5 is installed inside the feeding pipe 1, inclined and parallel to it, and rotates to propel the grain from left to right, achieving continuous conveying. The drying jacket 8... The drying sleeve 8 is fitted outside the feeding pipe 1 and is inclined at the same angle to form an annular drying chamber. Hot air enters the drying sleeve 8 and heats the surface of the feeding pipe 1, thereby indirectly drying the grain inside. Multiple horizontal pipes 9 are arranged in a circumferential array around the drying sleeve 8. Each horizontal pipe 9 is equipped with multiple equally spaced nozzles 10. The nozzles 10 extend into the interior of the drying sleeve 8 and are used to spray hot air into the drying sleeve 8 to form a uniform airflow field and improve drying efficiency. The air holes 101 are distributed on the outer wall of the feeding pipe 1 and come into direct contact with the hot airflow formed by the nozzles 10 inside the drying sleeve 8. The air holes 101 allow heat to be conducted through the wall of the feeding pipe 1 to the grain inside, enhancing the drying effect.

[0023] Grains enter the feed pipe 1 from the feed hopper 3. The feeding auger 5 rotates and pushes the grains to move from left to right along the inclined direction. During the conveying process, the nozzles 10 in the drying jacket 8 spray hot air to heat the feed pipe 1. The air holes 101 on the feed pipe 1 allow the heat to be transferred into the pipe and come into contact with the grains. During the conveying process, the grains gradually lose some moisture, achieving the purpose of preliminary drying. The dried grains are finally discharged through the discharge pipe 4 and enter the next process or storage stage. This equipment combines the conveying and drying functions into one, saving space and reducing the number of equipment. It dries the grains through indirect heating, avoiding the dust problem caused by direct blowing.

[0024] Furthermore, a rotating rod 6 is fixedly connected to the inner wall of the feeding auger 5, which is arranged with the left side lower than the right side. The rotating rod 6 is arranged parallel to the feeding pipe 1, the feeding auger 5 and the drying sleeve 8. A controller 18 is fixedly connected to the surface of the support frame 2 on the front left side.

[0025] The rotating rod 6 is fixedly connected to the inner wall of the feeding auger 5, and is inclined on the left and right, keeping parallel to the feeding pipe 1, the feeding auger 5 and the drying sleeve 8 to ensure structural coordination. The controller 18 is fixedly connected to the surface of the front left end support frame 2 for easy observation and operation by the operator. This equipment can realize centralized control of the entire conveying and drying process, and automatically adjust the heating power and conveying speed according to the moisture content of the material.

[0026] Furthermore, the right end of the rotating rod 6 is rotatably connected to the right side of the inner wall of the feeding pipe 1, the left end of the rotating rod 6 extends to the left side of the outer wall of the feeding pipe 1 and is rotatably connected thereto, and the first motor 7 is fixedly connected to the left side of the outer wall of the feeding pipe 1.

[0027] The right end of the rotating rod 6 is rotatably connected to the right side of the inner wall of the feeding pipe 1, ensuring that it can rotate freely during operation without axial displacement. The left end of the rotating rod 6 extends through the left outer wall of the feeding pipe 1 and forms a rotatable seal connection with it, ensuring that the rotating rod 6 can rotate normally. The left end of the rotating rod 6 is directly connected to the output shaft of the first motor 7 fixed to the outer wall of the feeding pipe 1. The first motor 7 provides power to drive the rotating rod 6 to rotate. This structural design gives the rotating rod 6 the characteristics of double support and external drive, making the operation more stable and the transmission efficiency higher.

[0028] Furthermore, the output shaft of the first motor 7 is fixedly connected to the left end of the rotating rod 6, and a protective cover 701 is provided outside the first motor 7. One side of the protective cover 701 is fixedly connected to the outer wall of the left side of the feeding pipe 1.

[0029] The protective cover 701 is fixedly connected to the outer left side of the feeding pipe 1, completely enclosing the first motor 7. It serves to prevent water, dust, and debris from entering, effectively protecting the first motor 7 from harsh working conditions. At the same time, it facilitates daily maintenance and improves the service life and safety of the equipment.

[0030] Furthermore, a hot air blower 12 is fixedly connected to one side of the circumferential surface of the drying jacket 8, a second motor 16 is fixedly connected to the top of the right end of the feeding pipe 1, connecting pipes 11 are fixedly connected between the left and right ends of the four horizontal pipes 9, and an air supply pipe 13 is fixedly connected to the air outlet of the hot air blower 12.

[0031] A hot air blower 12 is installed on one side of the circumference of the drying jacket 8. The function of the drying jacket 8 is to provide a heating environment for the material passing through it to accelerate the drying process. The hot air blower 12 is responsible for generating and supplying hot air into the drying jacket 8 to ensure that the heat can be evenly distributed throughout the drying area. The air duct 13 connects the air outlet of the hot air blower 12 to the center of one of the horizontal pipes 9, serving as a channel for hot air transmission to ensure that the hot air can be efficiently transferred to the material that needs to be dried.

[0032] Furthermore, the second motor 16 is arranged parallel to the drying sleeve 8 and the feeding pipe 1, and the end of the air duct 13 away from the hot air blower 12 is fixedly connected to the center of one of the horizontal pipes 9. The driven gear 14 is fixedly sleeved on the right end surface of the drying sleeve 8.

[0033] There are four horizontal pipes 9, which are located around the circumference of the drying jacket 8 and serve to distribute the hot air. The connecting pipe 11 connects all the horizontal pipes 9 to each other, ensuring that the hot air can flow freely between the horizontal pipes 9, thereby achieving a more comprehensive and uniform heating effect on the material. After the hot air blower 12 is started, the generated hot air enters one of the horizontal pipes 9 through the air duct 13 and begins to circulate in the entire network of horizontal pipes 9. As the hot air circulates continuously in the horizontal pipes 9 and the connecting pipe 11, the heat is gradually transferred to the drying jacket 8, promoting the evaporation of moisture. At the same time, the hot air ensures that each piece of material can fully contact the hot air, improving the drying efficiency.

[0034] Furthermore, the driven gear 14 is meshed with the driving gear 15 at the top, the output shaft of the second motor 16 extends into the inside of the driving gear 15 and is fixedly connected to its inner wall, a limiting ring 17 is fixedly sleeved on the left end of the surface of the feeding pipe 1, and the left end of the drying sleeve 8 is rotatably connected to the inner wall of the limiting ring 17.

[0035] The second motor 16 starts, driving the drive gear 15 to rotate. The power is transmitted to the driven gear 14 through gear meshing, causing the entire drying jacket 8 to rotate around the feed pipe 1. The hot air generated by the hot air blower 12 enters the horizontal pipe 9 through the air duct 13 and is evenly sprayed out at multiple nozzles 10. The rotation of the drying jacket 8 causes the position of the nozzles 10 to change continuously, forming a dynamic hot air curtain, which improves the heat exchange efficiency. The external rotation heating further accelerates the evaporation of grain moisture. Dynamic heating reduces the phenomenon of local overheating or uneven drying, ensuring the consistency of material quality.

[0036] Grains enter the feed pipe 1 through the feed hopper 3. The feeding auger 5 is driven by the first motor 7 to rotate and push the grains from left to right. The second motor 16 starts and drives the drive gear 15 to rotate. The drive gear 15 drives the driven gear 14 and the entire drying sleeve 8 to rotate through meshing transmission. The drying sleeve 8 rotates around the feed pipe 1, so that the position of the nozzle 10 changes continuously, forming dynamic drying. This dynamic heating method makes the hot air distribution more uniform and avoids the problems of local overheating or uneven drying. The limit ring 17 ensures that the drying sleeve 8 rotates smoothly and prevents eccentricity or shaking from affecting the sealing.

[0037] After the hot air blower 12 is started, it generates a high-temperature airflow. The hot air is sent into one of the horizontal pipes 9 through the air conveyor 13. The hot air in the horizontal pipe 9 is sprayed into the interior of the drying jacket 8 through multiple nozzles 10. All the horizontal pipes 9 are connected to each other through the connecting pipe 11 to form a complete hot air circulation. The hot air is evenly distributed in the drying jacket 8 and transfers heat to the grain inside through the air holes 101 on the wall of the feeding pipe 1. The hot air penetrates into the interior of the feeding pipe 1 and directly contacts the grain, improving the drying efficiency. The grain that has been conveyed and dynamically dried reaches the right end of the feeding pipe 1 and is discharged through the discharge pipe 4 to enter the subsequent processing stage.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
