Description

Technical Field

[0001] This utility model relates to the field of recycled concrete preparation technology, specifically to mobile recycled concrete preparation equipment. Background Technology

[0002] The process of preparing recycled concrete typically involves crushing waste concrete blocks, screening them to obtain aggregates of the appropriate particle size, and then transporting them to a concrete mixing plant for recycled concrete preparation. After the concrete is prepared, large concrete trucks are used to transport the recycled concrete from the concrete pumping station to the site of use. However, for construction projects in remote locations, this method has drawbacks. Firstly, the limited access roads prevent large concrete trucks from navigating the site effectively. Secondly, the repeated transport of aggregates and materials severely restricts the production efficiency of recycled concrete. Therefore, it is necessary to design appropriate recycled concrete mixers to enable on-site concrete preparation. Utility Model Content

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0028] Example 1: See Figure 1-4A mobile recycled concrete preparation equipment includes a frame 16, with parallel wheels 15 mounted on the bottom of the frame 16. A tilting frame 20 is hinged to the top of the frame 16. A head beam 11 is fixed to one end of the head of the tilting frame 20. A tilting power device is fixed between the head beam 11 and the frame 16. A first portal frame 19 and a second portal frame 21 are fixed to the top of the tilting frame 20. An aggregate conveyor is fixed to the top of the first portal frame 19 and the second portal frame 21. The discharge port 27 of the aggregate conveyor is located directly above the inlet of the mixing drum 9. One end of the outer wall of the mixing drum 9 is rolled and supported on a rotating seat 22. The rotating seat 22 is fixed to the top of the tilting frame 20. The tail end of the mixing drum 9 is connected to the rotating power device. This mixer, with its mobile structure, allows for easy movement and enables on-site preparation of recycled concrete, replacing the traditional process of multiple material transports. This adapts to the needs of remote construction sites where large mixer trucks cannot access, enhancing the flexibility of recycled concrete preparation. The mixer facilitates the addition and unloading of aggregates during the preparation process, improving efficiency. In practice, when recycled concrete is needed, concrete aggregates are automatically fed into an aggregate conveyor, while the required cement, additives, and other materials are simultaneously adjusted and automatically transported to the mixing drum 9. A rotary power unit drives the mixing drum 9 to rotate, thus mixing the aggregates and ultimately completing the preparation of recycled concrete.

[0029] Furthermore, a support platform 3 is provided at one end of the front of the frame 16, and a diesel generator 4 is fixed on the top of the support platform 3. The diesel generator 4 can be used to provide electrical energy to the mixer.

[0030] Furthermore, a connecting beam 2 is fixed to the head end of the support platform 3, and a towing hook 1 is fixed to one end of the head of the connecting beam 2. The towing hook 1 facilitates the connection of the entire mixer to a corresponding trailer, thereby enabling the entire mixer to be moved by the trailer.

[0031] Furthermore, the tilting frame 20 is hinged to the ear plate seat 17 via a pin 18, and the ear plate seat 17 is fixed to the top of the frame 16. The pin 18 facilitates the normal tilting of the tilting frame 20, thereby enabling the mixing drum 9 to operate in two different states. When not tilting, the mixing drum 9 can normally mix the aggregates. When unloading is required, the tilting frame 20 is driven to tilt, facilitating the unloading of concrete.

[0032] Furthermore, the tilting power device includes a tilting cylinder 12. The cylinder body of the tilting cylinder 12 is hinged to the frame crossbeam 14 via a first hinge seat 13. The frame crossbeam 14 is fixed between the frames 16. The piston rod end of the tilting cylinder 12 is hinged to the head crossbeam 11 via a second hinge seat 10. The tilting power device described above enables the rotation of the tilting frame 20. During operation, when the tilting frame 20 needs to be tilted, the tilting cylinder 12 is activated, driving the entire tilting frame 20 to rotate.

[0033] Furthermore, the aggregate conveyor includes a conveyor 30 fixed to the top of the first portal frame 19 and the second portal frame 21. A first conveying roller 26 is rotatably mounted at one end of the conveyor 30, and a second conveying roller 24 is rotatably mounted at the other end. A conveyor belt 25 is installed between the first conveying roller 26 and the second conveying roller 24. The first conveying roller 26 is connected to a conveyor motor 31. This aggregate conveyor can be used to automatically convey aggregates during the mixing process, thereby transporting the aggregates needed to prepare concrete into the mixing drum 9. During operation, the aggregates fall onto the conveyor belt 25, and the conveyor motor 31 is started. The conveyor motor 31 drives the first conveying roller 26, which in turn drives the conveyor belt 25, thus achieving the conveying of the aggregates via the conveyor belt 25.

[0034] Furthermore, the bearing seats of the first conveyor roller 26 and the second conveyor roller 24 are connected to the reaction frame 29 via a tensioning screw 28 to form a threaded transmission. The tensioning screw 28 can be used to tension the first conveyor roller 26 and the second conveyor roller 24, thereby realizing the tension adjustment of the conveyor belt 25.

[0035] Furthermore, the rotary power device includes a main shaft seat 7 fixed to the top of the head beam 11. A rolling main shaft 8 is rotatably mounted on the main shaft seat 7 via bearing seats. The rolling main shaft 8 is fixedly connected to the center of the tail end of the mixing tank 9. The rolling main shaft 8 is connected to the mixing motor 5 via a reducer 6. This rotary power device can be used to achieve mixing during the concrete preparation process. During operation, the mixing motor 5 is started, which drives the reducer 6, which in turn drives the rolling main shaft 8, which in turn drives the mixing tank 9 to rotate.

[0036] Furthermore, the outer wall of the mixing tank 9, which mates with the rotating base 22, is provided with an annular guide rail 23. This annular guide rail 23 ensures that the mixing tank 9 can rotate normally, thereby achieving mixing.

[0037] The working process and principle of this utility model: When recycled concrete needs to be prepared on-site, the mixer is connected to a trailer, which then moves the mixer to the location where the recycled concrete needs to be prepared. The mixer is then secured, and the aggregate is fed onto the conveyor belt 25 according to the required proportions. The conveyor motor 31 is started, driving the first conveyor roller 26, which in turn drives the conveyor belt 25, thus conveying the aggregate to the mixing drum 9. The rotary power unit is then started, driving the mixing motor 5, which in turn drives the reducer 6, which in turn drives the rolling spindle 8, which in turn drives the mixing drum 9 to rotate, thus preparing the recycled concrete. After preparation, the tilting frame needs to be tilted for unloading. The tilting cylinder 12 is started, driving the entire tilting frame 20 to rotate. The rotary power unit is then started again, causing the mixing drum 9 to rotate in the opposite direction, thus unloading the recycled concrete.
