Chain bucket type elevator

Abstract

The invention discloses a chain bucket type elevator which comprises a limiting device and an adjusting device. The limiting device comprises a chain, a chain wheel and baffles. The chain wheel is located on the inner surface of the chain and engaged with the chain. The baffles are located on the two sides of the chain and connected with the chain in a sliding manner. A hopper is fixedly installedon the outer surface of the chain. Sliding rods are fixedly connected to the outer surfaces of the two sides of the hopper correspondingly. Sliding grooves are formed in the outer surfaces of the sides, close to the hopper, of the baffles. The sliding rods are connected with the sliding grooves in a sliding manner. Gear teeth are fixedly installed on the outer circle face of the chain wheel. Grooves are formed in the outer surfaces of the rear ends of the gear teeth. Pin shafts are connected to the inner surfaces of the two sides of the chain in a rotating manner. Rectangular blocks are fixedly connected to the outer circle faces of the pin shafts. According to the elevator, the stability of the elevator in the operation process is guaranteed, the probability of separation from a transmission gear of the chain is reduced, the chain of the elevator can be adjusted rapidly, and the chain is always in a tension 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...

Problems solved by technology

[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
