Problems solved by technology

When the spiral stirring blade is used, the contact area between the stirring blade and the material to be mixed is small during the stirring process, the force along the circumferential direction of the barrel and the axial direction of the stirring shaft is small, the stirring time is long, and the stirring efficiency is poor.
When using a mixing shovel fixed to the mixing arm, on the one hand, the connection between the mixing arm, the stirring shaft and the mixing shovel needs to be considered, and the structure is complex; And the clumsy mixing shovel is difficult to open the flocculated material group, and the mixing effect is also unsatisfactory

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] 1. Technical requirements:

[0022] 1. The bottom plate of the reducer bracket needs a sealing device for the shaft end of the stirring shaft. After assembly, it is required to be free from warping, parallel, and the bolts are tightened without loosening when rotating.

[0023] 2. The gap between each shovel and the lining plate of the mixing drum is 3-5mm after installation.

[0024] 3. The two ends of the discharge door must be parallel, and the gap between them and the mixing drum should not be greater than 0.5mm.

[0025] 4. The mixer should run smoothly without impact, abnormal vibration and noise.

[0026] 2. Main technical parameters:

[0027] 1. Nominal capacity: 3000L

[0028] 2. Feed capacity: 5000L

[0029] 3. Productivity: 200-240m 3 / H

[0030] 4. Stirring shaft speed: 23.5r / min

[0031] 5. Dimensions: 4000mmx300mmx2000mm

[0032] According to t...

Abstract

The invention provides a novel double-horizontal-shaft concrete mixer, belongs to the technical field of building industry equipment, and aims to provide the novel double-horizontal-shaft concrete mixer. A transmission device (1) is arranged at one side of a mixing drum assembly (3), a discharge door assembly (5) is arranged below the transmission device (1), an upper cover (7) is arranged above the mixing drum assembly (3), a mixing device (4) is arranged in the mixing drum assembly (3) and penetrates through one end of the mixing drum assembly (3) through two main shafts to be connected with a reduction gearbox arranged on the transmission device (1), the other end of the mixing device (4) is connected with a shaft end seal and a bearing (2) arranged on the outer side of the mixing drum assembly (3), and an oil cup arranged on the shaft end seal and the bearing (2) is connected with an oil supply device (6) and an electric appliance assembly (8). Mixing quality is good, energy consumption is low, efficiency is high, bottom-opening-type discharge is achieved, labor intensity of workers is reduced, quality of concrete engineering is improved, and working requirements of different occasions are met.

Description

technical field [0001] The invention belongs to the technical field of construction industry equipment, and in particular relates to a novel twin-shaft concrete mixer. Background technique [0002] Concrete is one of the main building materials, widely used in industry, agriculture, transportation, national defense, water conservancy, municipal and civil infrastructure construction, and plays an important role in the national economy. But what use the most widely in building is the common concrete that is cementitious material with cement at present. In ordinary concrete, sand and stone act as the skeleton, filling the concrete and resisting the shrinkage of the concrete during the setting and hardening process. The cement slurry formed by cement and water wraps on the surface of the aggregate and fills the gaps between the aggregates. Concrete is widely used as the main building material because it has many characteristics that other materials do not have. Such as easy f...
