Description

The utility model relates to a movable cement mixing device.

The concrete used in general construction sites is transported out of the cement mixing plant by large cement mixer trucks. The mixing plant is equipped with cement storage tanks, sand and gravel storage tanks, conveyor belts and mixing tanks (see Figure 7), of which the mixing tank is a cylinder. It can be rotated in situ, using the blades in the tank to mix cement, sand and stone into concrete, and then distribute the mixed concrete to various construction sites. This approach has the following disadvantages:

1. Because the raw materials required by the mixing plant need to be shipped in large quantities from other places, and the concrete after mixing needs to be transported to the construction site by a large number of vehicles, which increases the number of transportation of concrete, which not only increases the transportation cost, but also makes transportation easier. Road damage.

2. Since the concrete is sent to the construction site by a sealed concrete truck, the actual loading capacity and mixing ratio cannot be measured, which will affect the construction quality and cause insufficient loading weight.

3. The concrete mixed in the mixing tank is sometimes poured into the concrete truck without being fully and uniformly mixed. Although the rotating drum on the transport truck is constantly rotating during transportation, the function of the rotating drum in the transport truck is only to rotate, so the concrete enters the construction site. There are still cases where the mixture is not evenly mixed.

4. During the transportation of concrete, although the rotating drum of the transport vehicle is constantly rotating, it will still harden. If more than a proportion of water or retarder is added, it will have a significant impact on the quality of the concrete.

The purpose of this utility model is to provide a movable cement mixing device, which can directly mix concrete on the construction site, and is easy to move, so as to ensure the quality of concrete, reduce transportation costs, and save costs.

The purpose of this utility model is achieved in this way: the movable cement mixing device is composed of a fixed bracket installed on the transport vehicle, a mixing drum and a transmission device, and the inner surface of the drum is provided with a wave surface to form a wave surface on the inner surface. Between the revolving screw blades, there is a stirring frame, the end of the mixing drum is equipped with a flip cover, and the center of the flip cover is equipped with a bearing installed on the cross bar, and the two sides of the cross bar are connected to the fixed bracket. The movable connecting rod and the two ends of the cross bar are respectively connected with the hydraulic cylinder, and the other end of the hydraulic cylinder is hinged on the support rods fixed on the rear sides of the two sides of the frame. When in use, the concrete mixed well in the drum can be discharged by the inner hydraulic cylinder in time while the drum is rotating.

The utility model has the advantage that the device is easy to move, and the device can be used to directly mix concrete on the construction site, which can not only ensure the quality of the concrete, but also reduce the number of times of transportation during the concrete production process, thereby reducing the cost and benefiting the protection of the road surface.

Below in conjunction with accompanying drawing, describe in detail the concrete structure of the present utility model and working conditions thereof.

Refer to Figure 1-4 movable cement mixing device, which includes:

A fixed bracket 2 is arranged at the rear of the transport vehicle 1. The top of the bracket 2 has a left and right support rod 21 and an inclined fixing seat 23. On the left and right support rods 21 and the fixing seat 23, corresponding I-shaped rollers are respectively provided. twenty two;

A stirring drum 3 is located between the left and right support rods 21 and the fixing seat 23, and a slide rail 31 is provided on the outer edge of the drum 3, and the slide rail 31 is fitted with the I-shaped roller 22;

A transmission mechanism is composed of a motor and a chain meshed with the gear 37 on the outer edge of the mixing drum 3;

On the inner surface of the mixing drum 3, there are revolving screw blades 4 that make the surface of the inner bore form a concave-convex undulating wave surface, and a stirring frame 5 is arranged between the revolving screw blades 4, and the center of the stirring frame 5 is provided with a mesh that allows the concrete raw materials to pass through. hole;

The outside of the mixing drum 3 ends is provided with a flip cover 31, and the center of the flip cover 31 is provided with a bearing 33. The bearing 33 is horizontally connected with the cross bar 34, and the two sides of the cross bar 34 are respectively connected with the movable connecting rod 35. The rods fixed on the left and right struts 21 are hinged, and the two ends of the cross bar 34 are respectively hinged to a hydraulic cylinder 36, and the hydraulic cylinder 36 is hinged to the struts 21' on the rear sides of the fixed bracket 2.

When in use, put cement, sand, stone, and water in the mixing drum 3 according to the mixing ratio, start the motor (not shown in the figure) to drive the chain, and make the mixing drum 3 rotate axially, and the slide rail 31 and the I-shaped roller 22 The rolling friction prevents the displacement of the cylinder 3, and can reduce the frictional resistance. Since the center of the flip cover 32 is provided with a bearing 33, when the drum 3 rotates, the bearing 33 is fixed, but only the flip cover 32 rotates accordingly. The concave part formed by the revolving screw blade 4 in the drum 3 can guide the sand, stone and cement to roll and mix. At the same time, the mesh of the mixing frame 5 can be used to sieve the concrete material to be fully and evenly mixed. After the mixing is completed, While the drum continues to rotate, it rises by the contraction of the hydraulic cylinder 36 and the limit of the movable connecting rod 35, so that the concrete can follow the inclination of the drum 3 and the guidance of the revolving screw blade 4, and the concrete is discharged from the drum outlet 6. Spill out, concrete pressure injection can be poured on the building, after the pouring of concrete is completed, lift cover 32 before being covered by hydraulic cylinder 36, rinse with water jet 38 sprays, make lift cover 32 to be able to tightly cover.

With reference to Fig. 5, when this device is used in the construction site that concrete demand is less, available a gravel car 7 that has conveyer belt, materials such as cement, sand, stone, water are input in mixing drum 3 and stirred.

With reference to Fig. 6, when being used in the construction site that concrete demand is bigger, then can add metering and conveying equipment 8 on the front side of transport vehicle 1, this equipment 8 is mainly made up of water tank 81, belt conveyor 82, and metering tank 83. Composition, its sand, stone, cement and other raw materials are transported to different metering tanks 83 by the above-mentioned gravel truck 7 at the same time, and the amount of materials in the concrete is measured and controlled by the microcomputer, and sent to the drum 3 by the conveyor belt. The water in the cabinet 81 can be pumped into a metering tank 83 by a water pump, then poured into the drum 3, and wash the inlet along the trend, so as to achieve direct and uniform mixing, save transportation costs, ensure the quality of concrete, and be convenient to use.
