Technical field:

[0001] The present application relates to the technical field of drying equipment, and in particular to a lifting device for a grain dryer. Background technology:

[0002] A grain dryer is a hot air drying box that uses a rotary heating device to generate large amounts of hot air in a short period of time. This high temperature treatment kills insect eggs, completely solving the grain drying problem. With improved grain varieties, rising yields, and increased national investment in grain drying equipment, the construction of large, medium, and small grain drying facilities is increasing. Choosing a high-quality, long-lasting, cost-effective, reliable, and highly automated dryer is crucial.

The hot air unit includes a burner, a heat exchanger and a fan, and the lifting unit includes a spiral feeding mechanism.

[0004] This patent uses a spiral feeding mechanism to transport grains. During the transportation process, the squeezing and friction of the spiral auger can easily cause the grain particles to break, affecting the grain quality. Utility model content:

[0005] In order to solve the above technical problems, the present invention provides a grain dryer lifting device, which solves the technical problem that grain particles are easily damaged during the drying and transportation process. In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A bracket, with a bucket elevator provided on one side of the bracket in a fixed structure manner;

[0008] A sidewall belt conveyor is located below the discharge port of the drying bin of the grain dryer. The sidewall belt conveyor is connected to the bracket in a fixed structure, and the output end of the sidewall belt conveyor is set at the feed port of the bucket elevator.

[0009] Side baffles, both sides of the baffles are respectively arranged on both sides of the main frame of the side baffle belt conveyor in a fixed structure manner;

[0010] A connecting plate is arranged between the two side baffle plates in a fixed structure;

[0011] The brush strip is connected to the connecting plate in a fixed structure, and the brush strip extends toward the sidewall belt conveyor.

[0012] Furthermore, the bucket elevator includes a casing, in which a transmission roller and a redirecting roller are arranged in a rotating structure. The transmission roller is arranged at the upper part of the casing, and the redirecting roller is arranged at the lower part of the casing. The transmission roller and the redirecting roller are connected by a belt, and the belt is provided with a plurality of hoppers in a fixed structure. A motor for driving the transmission roller to rotate is also provided outside the casing.

[0013] Furthermore, the redirecting roller comprises two discs arranged in parallel and at intervals, and a plurality of side ribs are evenly spaced and arranged on the outer circumferences of the two discs in a fixed structure.

Specific implementation method:

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will now be described in further detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the present invention. The specific implementation scheme of the present invention is as follows:

[0027] The grain dryer lifting device includes a bracket 1, a bucket elevator 2 is fixedly provided on one side of the bracket 1; a sidewall belt conveyor 4 is located below the discharge port of the drying bin 3 of the grain dryer, the sidewall belt conveyor 4 is connected to the bracket 1 in a fixed structure, and the output end of the sidewall belt conveyor 4 is provided at a feed port of the bucket elevator 2; by providing the sidewall belt conveyor 4 and the bucket elevator 2 instead of the spiral feeder, the extrusion and friction of the grain are avoided, the integrity of the grain particles during the transportation process is ensured, and the grain quality is improved;

[0028] Side baffles 5 are respectively provided on both sides of the main frame of the side guard belt conveyor 4 in a fixed structural manner, and a connecting plate 6 is provided between the side baffles 5 in a fixed structural manner. The connecting plate 6 is provided with a brush strip 7 in a fixed structural manner. The brush strip 7 extends toward the side guard belt conveyor 4, and can prevent food from spilling while ensuring the conveyor belt of the side guard belt conveyor 4 passes.

[0029] Specifically, the bucket elevator 2 includes a casing 21, in which a transmission roller and a redirecting roller 22 are arranged in a rotating structure. The transmission roller is arranged at the upper part of the casing 21, and the redirecting roller 22 is arranged at the lower part of the casing 21. The transmission roller and the redirecting roller 22 are connected by a tape, and the tape is provided with a plurality of hoppers in a fixed structure. A motor for driving the transmission roller to rotate is also provided outside the casing 21.

[0030] like Figure 3 As shown, the redirecting roller 22 with a cage structure includes two discs 221 arranged in parallel and at intervals. The outer circumferences of the two discs 221 are evenly spaced with a number of side ribs 222 in a fixed structure. By setting the redirecting roller as a cage structure, when part of the grain is pressed between the redirecting roller and the belt, it can enter the interior of the redirecting roller through the side ribs, avoiding the flattening of the grain particles and further improving the quality of the grain.

[0031] It should be noted that a circulation channel 8 extending into the drying bin 3 is provided at the upper part of the casing 21, a unloading channel 9 is provided at the lower part of the circulation channel 8, a conversion plate 10 is provided between the unloading channel 9 and the circulation channel 8, and a hinge shaft 11 is fixedly provided at the lower part of the conversion plate 10. The hinge shaft 11 is connected to the casing 21 in a rotating structure, and the hinge shaft 11 extends to the outside of the casing 21 and is fixedly provided with an adjusting rod 12. The middle part of the adjusting rod 12 is connected to the hinge shaft 11, and pull ropes 13 are provided at both ends of the adjusting rod 12. When the circulation drying is completed, the adjusting rod 12 is pulled by the pull rope 13 to control the grain to enter the unloading channel 9 to meet the unloading needs.

[0032] It should be noted that a baffle is provided inside the housing 21 for supporting the conversion plate 10 and limiting the position of the conversion plate 10 .

[0033] The sidewall belt conveyor 4 itself has motor-type power. Wave-shaped vertical skirts 14 are set on both sides of the conveyor belt of the sidewall belt conveyor 4 to prevent food from spilling during transportation. The conveyor belt is a Teflon conveyor belt 15 with high temperature resistance.

[0034] The working principle and working process of this utility model are as follows:

[0035] First, start the bucket elevator 2 and the sidewall belt conveyor 4, and put the grain into the casing 21 through the outer feed port of the bucket elevator 2. The grain is transported to the top of the casing by the hopper, turns after passing through the transmission roller, and throws the grain into the circulation channel 8. Then the grain falls into the drying bin 3 for drying. After drying to a certain extent, it falls onto the conveyor belt of the sidewall belt conveyor 4, and enters the casing 21 again through the sidewall belt conveyor 4 for the next cycle until the drying is completed. Pull the pull rope 13, and the pull rope 13 pulls the adjusting rod 12, and then the conversion plate 10 blocks the circulation channel 8 and opens the discharge channel 9. The grain enters the discharge channel 9 to meet the needs of unloading.
