Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, specifically relating to a feeding device for grain drying. Background Technology

[0002] In the grain drying process, to improve drying efficiency, the grain to be processed is usually conveyed to the feed inlet of the drying unit via a feeding device. Current technologies commonly use stationary screw conveyors or bucket elevators to transport the grain.

[0003] However, there are the following shortcomings: First, traditional feeding devices are mostly fixed structures, which cannot flexibly adjust the discharge direction according to the inlet position of the drying equipment, resulting in poor adaptability of the device and limiting the flexibility of equipment layout; Second, existing feeding structures generally neglect the simultaneous treatment of grain impurities and dust, resulting in a large amount of dust being scattered during the conveying process, which not only affects the working environment, but also easily causes blockage or pollution to the equipment in the subsequent drying process; In addition, some conveying devices with dust removal functions have complex structures and are difficult to maintain, which cannot meet the requirements of small and medium-sized grain processing plants for simple structure and stable operation. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a feeding device for grain drying, which can flexibly connect to the feed inlet of the drying device and has the ability to simultaneously and efficiently remove dust and impurities during the feeding process, so as to solve the technical problems of poor adaptability, unsatisfactory dust removal effect and inconvenient maintenance of existing equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A feeding device for grain drying includes a movable frame, a guide cylinder that tilts upward to the right is fixed on the upper side of the movable frame, a downward discharge pipe is fixed on the right end of the guide cylinder, and a hopper is fixed on the upper side of the guide cylinder near the left end. A spiral blade rod is installed on the inner side of the guide cylinder, and a driving component for driving the spiral blade rod to rotate is fixed on the left end of the guide cylinder.

[0007] A suction box is fixed on the upper side of the mobile frame near the left end. The spiral blade rod includes a tube and spiral blades fixed on the outside of the tube. The outer surface of the tube has evenly distributed suction holes. The left end of the tube is connected to the suction box.

[0008] Furthermore, the left end of the tube is inserted into the right side wall of the suction box, and a worm gear is fixed near the left end of the tube.

[0009] Furthermore, the driving component includes a fixed plate fixed on the guide cylinder, a worm gear meshing with the worm wheel is rotatably mounted on the fixed plate, and a motor for driving the worm gear to rotate is fixed on one side of the fixed plate.

[0010] Furthermore, an end cap is fixed at the left port of the suction box, and a partition with only the lower half is fixed in the middle of the inner side of the suction box. A fan is fixed on the end cap, a filter plate is inserted on the upper side of the suction box and pressed against the partition, and a collection box is inserted on the right side of the partition at the front of the suction box.

[0011] Furthermore, the filter plate includes a frame, a mesh plate is fixed to the inner side of the frame, and a baffle is fixed to the upper end of the frame.

[0012] Furthermore, the movable frame includes a base plate, on the upper surface of which a first bracket and a second bracket are fixed to provide inclined support for the guide cylinder, and on the lower side of the base plate are evenly distributed rollers.

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

[0014] By incorporating a roller structure into the movable frame, the mobility of the feeding device is enhanced, allowing for flexible adjustment of the guide cylinder's position. This enables the discharge pipe to accurately connect with the inlet of the drying equipment at different locations, solving the problems of fixed structure and poor adaptability of traditional feeding devices and improving the device's practicality and ease of operation.

[0015] By installing a spiral blade rod inside the feed tube and using a drive component to drive the worm gear and worm wheel, the linkage rotation of the tube body and the spiral blade is realized, which can efficiently and continuously transport the grain in the hopper towards the drying equipment, solving the problems of low conveying efficiency and unstable drive structure of existing equipment.

[0016] By opening dust suction holes on the surface of the feed cylinder and setting up a suction box structure at the left end of the feed cylinder, along with the fan, filter plate and collection box inside the suction box, the adsorption and collection of dust and impurities in the grain can be completed simultaneously during the grain conveying process. This solves the problem of the lack of dust removal function or poor effect of existing devices, effectively prevents dust from spreading and polluting the working environment, and avoids impurities from entering the drying equipment and causing blockage or pollution.

[0017] By incorporating baffles and insertable filter plates inside the suction box, the suction path and impurity retention effect are optimized. Combined with the collection box, this enables centralized processing of dust particles, improving the overall efficiency and ease of maintenance of the dust removal system, and solving the problems of complex structures and inconvenient cleaning in traditional dust removal systems.

[0018] By using an obliquely installed guide cylinder and fixing it with two supports, the smoothness and structural stability of grain conveying are improved, and the problem of conveying blockage caused by unstable support or unreasonable inclination angle of the existing feeding structure is solved.

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figure 1 and Figure 2As shown, a feeding device for grain drying includes a movable frame 1; a guide cylinder 5 inclined to the upper right is fixed on the upper side of the movable frame 1; the guide cylinder 5 is used to transport the grain loaded during the feeding process; a downwardly extending discharge pipe 6 is fixedly connected to the right end of the guide cylinder 5, used to discharge the grain in the guide cylinder 5 into the feed inlet of the drying equipment; an open hopper 4 is fixed on the upper side of the guide cylinder 5 near the left end, used to feed raw grain into the guide cylinder 5; a spiral blade rod 3 is installed along the length direction in the middle of the inner side of the guide cylinder 5, used to push the grain along the guide cylinder 5 to the upper right under drive; a drive component 7 is installed on the outer side of the left end of the guide cylinder 5 to drive the spiral blade rod 3 to rotate, used to provide power output for spiral feeding; through the structural setting of the guide cylinder 5, the feeding device has the function of directional conveying, which is convenient for use with drying equipment.

[0029] A suction box 2 is fixed on the upper side of the mobile frame 1 near the left end. The suction box 2 is a hollow box structure, which is equipped with suction, filtration and collection functional components. The spiral blade rod 3 includes a hollow tube 32 arranged along the length of the guide cylinder 5. Multiple dust suction holes 34 are evenly arranged on the outer circumference of the tube 32 for sucking up fine impurities and dust generated with the flow of grain in the suction state. A spiral blade 33 arranged along the spiral direction is fixedly connected to the outside of the tube 32 for pushing the grain to the right as the tube 32 rotates. The left end of the tube 32 is connected to the suction box 2, so that a negative pressure environment is formed inside the suction box 2, thereby achieving the dust removal effect through the dust suction holes 34.

[0030] like Figure 1 and Figure 2 As shown, the left end of the tube body 32 is inserted and installed on the right side wall of the suction box 2 and communicates with the inner cavity of the suction box 2; a worm gear 31 that works in conjunction with the drive system is fixedly installed near the left end of the tube body 32 to receive the drive torque and drive the tube body 32 to rotate as a whole, thereby realizing the spiral conveying of grain and synchronous dust removal function.

[0031] like Figure 3 As shown, the driving component 7 includes a fixing plate 72 disposed at the left end of the guide cylinder 5. The fixing plate 72 is vertically mounted on the guide cylinder 5 and provides a mounting support surface. A worm 71 that meshes with the worm wheel 31 is rotatably mounted on the fixing plate 72. The worm 71 drives the worm wheel 31 to rotate through the meshing structure. A motor 73 that drives the worm 71 to rotate is mounted on one side of the fixing plate 72. The motor 73 outputs power to make the worm 71 rotate, thereby driving the tube body 32 and its spiral blades 33 to rotate through the transmission mechanism of the worm and the worm wheel, so as to realize the continuous conveying of grain.

[0032] like Figure 4As shown, an end cap 22 is sealed at the left port of the suction box 2. The end cap 22 is used to close the left opening of the suction box 2 and provide a fan mounting position. A fan 21 is fixedly installed on the end cap 22. When the fan 21 is working, it forms a negative pressure airflow inside the suction box 2, thereby sucking in impurities in the grain through the dust suction hole 34. A lower half of the partition 23 is fixedly installed in the middle of the inner cavity of the suction box 2. The partition 23 divides the internal space of the suction box 2 into upper and lower parts. A filter plate 24 is installed on the upper side of the suction box 2. The filter plate 24 presses down against the partition 23 to perform preliminary filtration of impurity particles in the suction airflow. A collection box 25 is set on the right side of the partition 23 on the front side of the suction box 2. The collection box 25 is inserted into the suction box 2 and communicates with the bottom of the filter plate 24 to receive the impurities and dust deposited after filtration, so as to realize the centralized storage of impurities.

[0033] like Figure 5 As shown, the filter plate 24 includes a frame 243 with an outer frame structure. The frame 243 supports the entire filter plate structure and facilitates installation and positioning. A mesh plate 242 is fixedly installed on the inner side of the frame 243. The mesh plate 242 is made of high-density woven metal wire or perforated stainless steel plate and is used to block tiny impurities from entering the fan 21 with the airflow. An integrated baffle 241 is fixedly installed at the upper end of the frame 243. The baffle 241 is used to further prevent dust from falling back and improve filtration efficiency and operational stability.

[0034] like Figure 6 As shown, the mobile frame 1 includes a bottom plate 12 at the bottom, which serves as a support platform for the entire machine, supporting the guide cylinder 5, the suction box 2, and the drive component 7. A first bracket 13 and a second bracket 14 are fixedly installed on the upper surface of the bottom plate 12. Both the first bracket 13 and the second bracket 14 are L-shaped or arc-shaped plates, used to support the guide cylinder 5 at an inclined angle and fix its position to ensure a stable and consistent guiding direction. Multiple rollers 11 are evenly fixedly installed on the lower side of the bottom plate 12. The rollers 11 are located at the four corners or four edges of the bottom of the bottom plate 12, allowing the entire device to move smoothly on the ground, facilitating docking with drying equipment in different locations, thereby improving the adaptability and flexibility of the feeding device.

[0035] The working principle of this utility model is as follows: When drying and feeding grain, the moving frame 1 moves the guide cylinder 5 so that the discharge pipe 6 is aligned with the feed inlet of the drying device. At this time, the grain is loaded into the hopper 4. The motor 73 drives the worm wheel 31 through the worm gear 71 to drive the tube body 32 and the spiral blade 33 to rotate, thus pushing the grain upward, thereby completing the feeding. At the same time as the grain is fed, the suction box 2 continuously sucks air so that the dust suction holes 34 on the tube body 32 suck away all the fine impurities and dust in the grain. The sucked-away dust and fine impurities enter the suction box 2, are filtered by the filter plate 24, and finally fall into the collection box 25, thus completing the efficient dust and impurity removal treatment of the grain while feeding it.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
