A chain bucket elevator

Abstract

The invention discloses a chain bucket elevator, which includes a limiting device and an adjusting device; the limiting device includes a chain, a sprocket, and a baffle, and the sprocket is located on the inner surface of the chain and meshed with the chain. The baffle is located on both sides of the chain, and it is slidingly connected with the chain. The outer surface of the chain is fixedly equipped with a hopper, and the outer surfaces of both sides of the hopper are fixedly connected with slide bars. The side of the baffle close to the hopper The outer surface is provided with a chute, and the sliding rod is slidably connected with the chute. The outer surface of the sprocket is fixedly equipped with gear teeth, and the outer surface of the rear end of the gear teeth is provided with grooves. A pin shaft is rotatably connected to the side inner surface, and a rectangular block is fixedly connected to the outer circular surface of the pin shaft. The invention ensures the stability of the hoist during operation, reduces the probability of the chain detaching from the transmission gear, and can quickly adjust the chain of the hoist so that the chain is always in a tensioned state.

Description

technical field [0001] The invention relates to the technical field of material transportation, in particular to a chain bucket elevator. Background technique [0002] As an efficient vertical lifting equipment, the chain bucket elevator is widely used in the transportation of mineral materials, cement clinker, gypsum and other materials. [0003] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: 1. When the chain bucket elevator is transporting stones, the chain often breaks away from the sprocket, resulting in an emergency stop of the machine and affecting production The normal operation of the chain will increase the friction between the sprocket and the chain when the chain is running, resulting in wear and tear on both the sprocket and the chain, reducing the stability of the chain operation, and the hopper is full of materials when the chain is running If there is an offset...

[0003] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: 1. When the chain bucket elevator is transporting stones, the chain often breaks away from the sprocket, resulting in an emergency stop of the machine and affecting production The normal operation of the chain will increase the friction between the sprocket and the chain when the chain is running, resulting in wear and tear on both the sprocket and the chain, reducing the stability of the chain operation, and the hopper is full of materials when the chain is running If there is an offset, it will be difficult to recover, resulting in a decrease in transportation efficiency; 2. After the chain is used for a long time, the worn part will cause the connection of the shaft on the chain to loosen. When the chain bucket is full of materials, the chain will be pressed to bend the chain, reducing the The stability of the transportation increases the difficulty of the transportation process; 3. When the existing transportation belt is used to transport the stones in the way of lifting, the slope of the transportation belt needs to be small, and the long-term transportation For stones, the chain will loosen and shake when the chain moves, which will reduce the stability of the elevator transportation, and the opening of the existing hopper has not been improved for the stones. The opening of the traditional hopper is small. When loading stones, It is time-consuming to adjust the angle at which stones enter the hopper, and the hopper will vibrate when transporting stones and cause scratches to the hopper itself
