Detailed implementation manners

[0021] In order to describe the present utility model more clearly, the present utility model will be further described below with reference to the accompanying drawings.

[0022] In the following description, example details are given to provide a deeper understanding of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. It should be understood that the specific embodiments are only used to explain the present utility model and are not used to limit the present utility model.

[0023] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the described features, wholes, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components or combinations thereof.

[0024] Since when the bucket elevator has too much material, the ascending hopper 3 and the descending hopper 3 will have an unbalanced weight. When the hopper 3 filled with bulk materials ascends, due to its excessive gravity, it will cause unstable transportation, resulting in shaking and the bulk materials falling out. In severe cases, it may even cause jamming, stalling and even more serious safety problems. And at this time, the bucket elevator needs to be repaired, which greatly affects the production efficiency. Therefore, there is an urgent need for a reasonable and stable-transporting bucket elevator to solve the above-mentioned technical problems.

[0025] Please refer to Figures 1 - 5, A bucket elevator with stable transportation of the present utility model includes a fuselage 1. Inside the fuselage 1, a traction device 2 and a hopper 3 are provided. The traction device 2 includes an upper traction motor 21, a lower traction motor 22, a traction wheel 23, and a traction chain 24. Traction wheels 23 are respectively sleeved on the output shafts of the upper traction motor 21 and the lower traction motor 22. A connection groove 231 is provided on the traction wheel 23, and the traction chain 24 is embedded in the connection groove 231. The hopper 3 is fixedly arranged on the traction chain 24; the fuselage 1 includes a feed chute opening 5 and a discharge chute opening 6. A guide rail 4 is provided inside the fuselage 1. The guide rail 4 is sleeved on the traction wheel 23. An installation groove 41 is provided on the guide rail 4. The traction chain 24 is fixed to both sides of the guide rail 4 through the installation groove 41. By embedding the traction chain 24 in the connection groove 231 of the traction wheel 23, it is ensured that when the traction wheel 23 rotates, the traction chain 24 will not break away from the traction wheel 23. At the same time, the guide rail 4 is sleeved outside the traction wheel 23, and the traction chain 24 is fixedly arranged on the guide rail 4. In this application, the guide rail 4 is a conveyor belt made of metal material, specifically, it can be a stainless steel conveyor belt, which has high strength, corrosion resistance, and large tensile strength and is not easily deformed. It is particularly suitable as a transmission component for driving the traction chain 24, and can maximally avoid the shaking caused by the weight imbalance of the ascending hopper 3 and the descending hopper 3 on the traction chain 24.

[0026] Generally, to increase the transportation stability of the hopper 3, the length of the conveyor belt or the conveyor chain is reduced to make it in a taut and straight state to reduce shaking. However, there are also problems such as short service life of the conveyor belt and the conveyor chain, and easy breakage due to excessive tension, which poses a great safety hazard. Therefore, in order to increase the transportation efficiency and stability of the bucket elevator of the present utility model, a connection groove 231 is provided on the traction wheel 23, the traction chain 24 is embedded into the connection groove 231, and pitting points 232 are provided in the connection groove 231. Specifically, the pitting points 232 are metal welding points that are welded by electric welding and slightly protrude, which are used to increase the contact area between the traction wheel 23 and the traction chain 24, make the friction force between the traction chain 24 and the traction wheel 23 larger, improve the grasping force of the traction chain 24, so that the traction chain 24 can stably lift and lower the hopper 3 with a greater traction force. And the traction chain 24 is fixedly arranged on the guide rail 4, and the traction chain 24 and the guide rail 4 are balanced with each other, effectively preventing the problem of left and right shaking of the hopper 3 during the ascending process, enabling the hopper 3 to ascend smoothly, reducing shaking, and making the traction chain 24 in a stable transportation state through the pitting points 232 and the guide rail 4 to achieve the purpose of stable hopper transportation.

[0027] During use, the upper traction motor 21 and the lower traction motor 22 are started to operate to drive the traction wheel 23 to rotate. At the same time, the traction chain 24 on the traction wheel 23 moves accordingly. Since the traction chain 24 will shake when being pulled by the gravity of the hopper 3 itself and drive the hopper 3 to shake, the traction chain 24 can reduce shaking through the guide rail 4.

[0028] Furthermore, the traction chain 24 further includes a connecting chain 241 and a transmission chain 242. One end of the connecting chain 241 has an installation notch 243. The hopper 3 is provided with a connecting hole. The connecting chain 241 connects the transmission chain 242 through the installation notch 243 and is fixedly connected to the hopper 3 through the connecting hole. The connecting chain 241 passes through the transmission chain 242 and the connecting hole on the hopper 3 through the installation notch 243, and finally the connecting chain 241 and the hopper 3 are fixed by a nut to ensure the stable connection between the hopper 3 and the traction chain 24.

[0029] In this embodiment, please refer to Figure 1 , a cleaning hatch 61 for cleaning materials is also provided on the side of the discharge chute opening 6. After the bucket elevator finishes working, workers still need to clean the internal materials. In order to ensure that workers can clean the materials safely and conveniently, the cleaning hatch 61 is provided on the side of the discharge chute opening 6, so that workers can open the cleaning hatch 61 from the side to clean the residual materials without leaning into the discharge chute opening 6 for cleaning. After cleaning, it can be closed, and relevant locking devices can be further set to prevent the cleaning hatch 61 from being opened during the operation of the bucket elevator. Since this method is a prior art, it will not be elaborated here; by setting the cleaning hatch 61, the safety of workers is ensured and the cleaning efficiency is improved.

[0030] In this embodiment, the angle between the discharge chute opening 61 and the fuselage 1 is 30°. In order to reduce the impact of materials on the discharge chute opening and protect the integrity of the materials themselves, the discharge chute opening is configured as an inclined surface opening with an angle of 30° relative to the fuselage to reduce the impact force caused when the materials are thrown out.

[0031] The advantages of the present utility model are as follows:

[0032] 1) The hopper of this product can remain stable during the upward and downward transportation. By setting the pitting to increase the friction of the traction chain and cooperating with the guide rail, the transportation stability is further improved, and the production efficiency and safety of the bucket elevator are improved.

[0033] The above discloses only several specific embodiments of the present utility model, but the present utility model is not limited thereto. Any change that can be thought of by those skilled in the art should fall within the protection scope of the present utility model.
