Novel cement stirring tank

Abstract

The novel cement stirring tank comprises a tank body with an opening in the front end, a front base and a rear base, a front connecting disc is arranged outside the front end of the tank body and rotationally connected with the front base through a rotary supporting device, and a rear connecting disc is arranged in the center of the rear end of the tank body and rotationally connected with the rear base through a transmission device. The rotary supporting device comprises a rotary outer ring and a rotary inner ring sealing cover, the rotary outer ring is fixedly connected with the front connecting disc, the rotary inner ring sealing cover is fixedly installed on the front base, and the end, close to the tank body, of the rotary inner ring sealing cover is fixedly connected with a rotary inner ring. The rotary outer ring is sleeved with the rotary inner ring and is in running fit with the rotary outer ring, the contact face of the rotary outer ring and the rotary inner ring is an inclined face or an arc-shaped face, the outer portion of the rotary outer ring is sleeved with an outer gear ring, and the outer gear ring is fixedly connected with the front connecting disc.

Description

technical field [0001] The invention relates to the technical field of cement mixer trucks, in particular to a novel cement mixing tank. Background technique [0002] Existing cement mixer truck tank body rotation work adopts the rear-end reducer and the front double supporting wheel structure. In the construction of coal mines and engineering tunnels, the space height of the passage section is limited and the tilt angle of the tank body is lowered or the transportation distance is relatively short. In the long-distance use, the sealing cover will be installed at the inlet and outlet of the cement mixing tank, and because the cement mixing tank is constantly rotating during transportation to prevent the cement in the tank from solidifying, this will affect the relative rotation accuracy of the inlet and outlet positions. High requirements are put forward, and the commonly used double supporting wheel slewing mechanism is due to the production process method, which needs to m...

[0002] Existing cement mixer truck tank body rotation work adopts the rear-end reducer and the front double supporting wheel structure. In the construction of coal mines and engineering tunnels, the space height of the passage section is limited and the tilt angle of the tank body is lowered or the transportation distance is relatively short. In the long-distance use, the sealing cover will be installed at the inlet and outlet of the cement mixing tank, and because the cement mixing tank is constantly rotating during transportation to prevent the cement in the tank from solidifying, this will affect the relative rotation accuracy of the inlet and outlet positions. High requirements are put forward, and the commonly used double supporting wheel slewing mechanism is due to the production process method, which needs to meet the high slewing accuracy of the tank inlet and outlet for a long time. The manufacturing cost is extremely high, and it is difficult to achieve, so it is currently in use For all products, the rotary seal is as short as ten days and a half months, and it takes three or two months to repair and replace parts, which consumes manpower and the vehicle utilization rate is low.

At the same time, the rotary power of the existing cement mixer tanks all comes from the power plant of the car. When the power of the car fails and there is no available power source around the tank and the tank cannot operate, the cement mixer tank cannot rotate, resulting in cement solidification. It cannot be discharged in the tank, and manpower is required to enter the tank to remove the solidified cement manually, which consumes a lot of manpower and causes unnecessary economic losses.
