[0001] The utility model belongs to the technical field of concrete production equipment, and particularly relates to a production and conveying device for concrete admixtures. Background Art

[0002] Concrete admixtures, simply referred to as admixtures, refer to substances added before or during the mixing of concrete to improve the performance of concrete. Most concrete admixtures are powders.

[0003] During the discharge and transportation of the admixture onto the conveying device, a large amount of dust will be raised, which will have a certain impact on the working environment. Therefore, a screw conveyor is often used for transportation. However, the traditional screw conveyor is not convenient to clean its interior after use. As the core component of the conveying device, the maintenance of the screw blade is very important. If not cleaned for a long time, the dirt accumulated inside the screw may cause increased wear of the equipment, even lead to failures, and shorten the service life of the equipment.

Detailed implementation

[0018] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0019] As Figures 1-3 shown, a concrete admixture production and conveying device includes a base 1 and a conveying device body. The conveying device body is inclined and installed on the upper side of the base 1. The conveying device body includes a lower housing 2. The rear side of the lower housing 2 is hinged with an upper housing 3. The lower housing 2 and the upper housing 3 can jointly form a complete pipe body. An auger 4 matching the upper housing 3 and the lower housing 2 is rotatably connected inside the upper housing 3. A feed hopper 5 communicating with the inside of the upper housing 3 is installed on the outer side of the left part of the upper housing 3. A conveying motor 6 is installed at the left end of the upper housing 3. The output end of the conveying motor 6 is in transmission connection with the auger 4. A fixing component for fixing the upper housing 3 is installed on the front side of the lower housing 2;

[0020] The number of the fixing components is three groups, and they are evenly spaced along the direction of the auger 4. The fixing component includes a screw 7. The lower end of the screw 7 is hinged to the front side of the lower housing 2 in the front and back directions. A runner 8 is threadedly connected to the upper side of the screw 7. A card slot 9 matching the screw 7 and the runner 8 is fixedly installed on the front side of the upper housing 3;

[0021] Two sealing strips 10 distributed in the front and back are installed on the upper side of the lower housing 2. The sealing strips 10 match the upper housing 3.

[0022] When the present utility model is in use, the concrete admixture to be conveyed is added to the inside of the feed hopper 5. The upper housing 3 and the lower housing 2 are in a closed state, and the fixing component locks them. The conveying motor 6 drives the auger 4 to rotate, so as to realize the conveying of the concrete admixture. When it is necessary to clean the inside of the conveying device, the fixing component can release the upper housing 3, and the upper housing 3 can be folded backward. At this time, it is convenient to clean the inside of the conveying device.

[0023] During use, the bolt is inserted into the inner side of the upper chute 9, and the rotating wheel 8 is tightened. At this time, the upper housing 3 is fixed. The design of the lower housing 2 and the upper housing 3 that can be folded up and down can be combined into a complete pipe body during use, without raising dust during transportation, and enabling the conveying equipment to be opened from the middle when not in use, facilitating the staff to regularly clean the inside of the auger 4, reducing equipment wear, and extending the service life of the equipment; the setting of the three groups of fixing components enables the upper housing 3 to be evenly fixed, and at the same time, the cooperation of the three groups of bolts, rotating wheels 8 and chutes 9 makes the operation of the fixing components simple; the sealing strip 10 can increase the sealing performance between the upper housing 3 and the lower housing 2, fill the gap between the upper housing 3 and the lower housing 2, prevent admixtures from entering, and improve the reliability of the conveying equipment.

[0024] A lifting component is also provided on the lower side of the conveying equipment body. The lower left side of the lower housing 2 is hinged to the base 1 up and down.
