Description

Technical Field

[0001] The utility model relates to the technical field of grain transportation, in particular to an automatic anti-blocking device for a grain transportation bucket elevator. Background Art

[0002] Grain transportation refers to the process of transporting grain from one location to another, which usually involves multiple links, including harvesting, storage, processing and transportation. In the grain industry, bucket elevators are often used to lift grain from storage warehouses to processing equipment or other storage facilities. They are one of the important equipment for grain processing and transportation.

[0003] For example, Chinese patent CN220033423U discloses a bucket elevator, which uses a driving motor to drive the paddle wheel to rotate, thereby automatically discharging the material in the lifting hopper, making it discharge evenly and avoiding blockage. However, the driving motor and the paddle wheel are arranged in the lifting hopper. When multiple lifting hoppers are used to lift materials, the lifting mechanism that drives the lifting hoppers to rise and fall has a heavy load and high energy consumption, which is not conducive to saving resources. Therefore, we propose an automatic anti-blocking device for grain conveying bucket elevator. Utility Model Content

[0004] The utility model aims to provide an automatic anti-blocking device for a grain conveying bucket elevator, which has the effects of preventing blockage and saving resources.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: an automatic anti-blocking device for a grain conveying bucket elevator, comprising a cover shell, a lifting mechanism installed in the cover shell and a plurality of lifting hoppers installed on the lifting mechanism, the upper rotation of the lifting hopper is connected to a dredging mechanism, an elastic pressure block intermittently fitted with the dredging mechanism is installed on the inner wall of the lifting hopper, a transmission mechanism engaged with the dredging mechanism is installed on the lifting hopper, and a driving mechanism for driving the transmission mechanism to rotate is installed on the inner wall of the cover shell.

[0006] By adopting the above technical solution, the lifting mechanism lifts multiple lifting hoppers one by one to pour out the grains in the lifting hoppers. After the grains pass through the driving mechanism, the driving mechanism starts and drives the transmission mechanism to rotate. The transmission mechanism engages with the dredging mechanism to drive the dredging mechanism to rotate. When the dredging mechanism rotates, the powder attached to the corresponding position in the lifting hopper is dredged and discharged. The dredging mechanism also intermittently squeezes the elastic pressure block when rotating to dredge the inner wall of the lifting hopper, causing the inner wall of the lifting hopper to resonate, further facilitating the dredging and discharge of the powder attached to the inner wall of the lifting hopper at the corresponding position to prevent blockage, and using a driving structure to realize the rotational dredging of multiple lifting hoppers. The load on a single lifting hopper is light, which makes the lifting mechanism light in weight and low in energy consumption, which is conducive to saving resources.

[0007] The present invention is further configured as follows: the inner wall of the lifting hopper on the side away from the lifting mechanism is configured to be inclined.

[0008] By adopting the above technical solution, the inclined design makes it easier for the lifting hopper to scoop more grains at the bottom of the cover into the lifting hopper when it moves with the lifting structure.

[0009] The utility model is further configured as follows: the dredging mechanism includes a rotating shaft rotatably connected to the inner wall of the lifting hopper, and a bevel gear and a dredging blade installed outside the rotating shaft.

[0010] The present invention is further configured as follows: the bevel gear 1 is located outside the material lifting hopper, and the dredging blades are located inside the material lifting hopper.

[0011] By adopting the above technical solution, the driving mechanism starts to drive the transmission mechanism to rotate, and the transmission mechanism engages with the bevel gear to drive the rotating shaft to rotate. When the rotating shaft rotates, the dredging blades rotate inside the lifting hopper, and the powder attached to the corresponding position in the lifting hopper is dredged and discharged.

[0012] The present invention is further configured as follows: a plurality of dredging blades are provided on the rotating shaft and are distributed in a circular shape with equal distances, and the plurality of dredging blades intermittently squeeze the elastic pressing block.

[0013] By adopting the above technical solution, multiple dredging blades intermittently squeeze the elastic tooth blocks when dredging the inside of the lifting hopper, causing the inner wall of the lifting hopper to resonate, further facilitating the dredging of powder attached to the inner wall of the lifting hopper at the corresponding position to prevent blockage.

[0014] The utility model is further configured as follows: the transmission mechanism includes a guide shell installed on the lifting hopper, a rack plate slidably connected to the guide shell, a connecting spring connecting the rack plate and the inner wall of the guide shell, a side plate installed on the lifting hopper, a transmission roller rotatably connected to the side plate, and a gear and a bevel gear installed on the outside of the transmission roller.

[0015] The present invention is further configured as follows: the gear is engaged with the rack plate, and the second bevel gear is engaged with the first bevel gear.

[0016] By adopting the above technical solution, the driving structure starts to squeeze the rack plates on the front and rear sides, the connecting spring is compressed, and when the rack plate moves, it engages with the gear to rotate the transmission shaft. The rotating shaft drives the rotating shaft to rotate through the engagement of bevel gear 2 and bevel gear 1, thereby realizing the dredging and cleaning of the lifting hopper.

[0017] The present invention is further configured such that the inner wall of the guide housing is smooth.

[0018] By adopting the above technical solution, the rack plate moves more smoothly on the guide housing.

[0019] The utility model is further configured as follows: the driving mechanism includes a mounting bracket mounted on the inner wall of the cover shell, a bidirectional screw rotatably connected to the inner side of the mounting bracket, a driving motor mounted on the mounting bracket and driving the bidirectional screw to rotate, and a pressure plate threadedly connected to the outside of the bidirectional screw and slidingly connected to the inner wall of the cover shell.

[0020] The utility model is further configured as follows: the exterior of the bidirectional screw is provided with two sections of threads in opposite directions, and one side of the pressure plate slides back and forth on the inner wall of the mounting frame.

[0021] By adopting the above technical solution, the driving motor is started to drive the bidirectional screw to rotate, so that the two pressure plates are moved closer to or away from each other on the bidirectional screw, squeezing the rack plate to make the rack plate slide in the guide housing. When the rack plate moves, it engages with the gear to rotate the transmission shaft, and the rotating shaft is driven to rotate by the engagement of bevel gear 2 and bevel gear 1, thereby realizing the dredging and cleaning of the lifting hopper.

[0022] The beneficial effects of the utility model are:

[0023] 1. The lifting mechanism lifts multiple lifting hoppers one by one and pours out the grains in the lifting hoppers. When the grains pass through the driving mechanism, the driving mechanism starts and drives the transmission mechanism to rotate. The transmission mechanism engages with the dredging mechanism to drive the dredging mechanism to rotate. When the dredging mechanism rotates, the powder attached to the corresponding position in the lifting hopper is dredged and discharged. When the dredging mechanism rotates to dredge the inner wall of the lifting hopper, it also intermittently squeezes the elastic pressure block, causing the inner wall of the lifting hopper to resonate, further facilitating the dredging and discharge of the powder attached to the inner wall of the lifting hopper at the corresponding position to prevent blockage.

[0024] 2. A driving structure is used to realize the rotation dredging of multiple lifting hoppers. The load on a single lifting hopper is light, which makes the lifting mechanism light in weight and low in energy consumption, which is conducive to saving resources.

[0033] When the lifting mechanism 2 lifts the multiple lifting hoppers 3 one by one and pours out the grains in the lifting hoppers 3 and passes through the driving mechanism 7, the driving mechanism 7 starts and drives the transmission mechanism 6 to rotate. The transmission mechanism 6 engages with the dredging mechanism 4 to drive the dredging mechanism 4 to rotate. When the dredging mechanism 4 rotates, the powder attached to the corresponding position of the lifting hopper 3 is dredged and discharged. When the dredging mechanism 4 rotates to dredge the inner wall of the lifting hopper 3, it also intermittently squeezes the elastic pressure block 5, so that the inner wall of the lifting hopper 3 resonates, further facilitating the dredging and discharge of the powder attached to the inner wall of the lifting hopper 3 at the corresponding position to prevent blockage, and using a driving structure 7 to realize the rotation dredging of multiple lifting hoppers 3. The load on a single lifting hopper 3 is light, which makes the lifting mechanism 2 light in weight and low in energy consumption, which is conducive to saving resources.

[0034] The inner wall of the lifting hopper 3 away from the lifting mechanism 2 is set to be inclined. The inclined design makes it easier for the lifting hopper 3 to scoop more grains at the bottom of the cover 1 into the lifting hopper 3 when it moves with the lifting structure 2.

[0035] The dredging mechanism 4 includes a rotating shaft 41 rotatably connected to the inner wall of the lifting hopper 3 and a bevel gear 42 and a dredging blade 43 installed on the outside of the rotating shaft 41.

The plurality of dredging blades 43 also intermittently squeeze the elastic tooth block 5 when dredging the interior of the lifting hopper 3, so that the inner wall of the lifting hopper 3 resonates, further facilitating the dredging and discharge of powder attached to the inner wall of the lifting hopper 3 at the corresponding position to prevent blockage.
