Technical Field

[0001] The utility model relates to the technical field of mixing, in particular to mixing equipment for road construction. Background Art

[0002] Currently, most roads are paved with asphalt, but some roads are still paved with cement concrete. Cement concrete pavements include plain concrete, reinforced concrete, continuously reinforced concrete, prestressed concrete and other types of pavements.

[0003] In the prior art with publication (announcement) number: CN217395324U and publication (announcement) date: 2022-09-09, a concrete mixing device for road construction is proposed, which raises the problem that "a concrete mixing device is generally set up on the construction site during concrete road construction, but the existing concrete mixing device is inconvenient to move, and the road will move forward during road construction. After moving to a certain distance, it will become very troublesome to use or transport concrete, affecting the construction period", and solves the above problem.

[0004] However, in the above-mentioned prior art, the mixing barrel needs to be rotated each time material is added or discharged, so as to adjust the position of the feeding port to facilitate feeding or discharging, resulting in poor convenience of use. Therefore, a mixing equipment for road construction is proposed to optimize the above-mentioned prior art. Utility Model Content

[0011] As a further solution of the utility model: a material guide trough is provided on the outer side of the discharge port, and the material guide trough is connected to the outer side of the discharge port by damping rotation. After the material guide trough is flipped upward, a positioning effect is formed by damping limitation. After the material guide trough is flipped downward, the tail end edge of the material guide trough abuts against the bottom surface of the discharge port, forming a limiting effect on the material guide trough.

[0025] The wheels 4 cooperate with the auxiliary wheels 9 to form a four-point stable support for the mixing barrel 2 installed between the mounting plates 1 to prevent the mixing barrel 2 from rotating. In addition, with the setting of a separate discharge port 5 and a feeding port 6, concrete raw materials can be easily added and discharged. There is no need to rotate the mixing barrel when adding materials, making the addition of materials more convenient.

[0026] See also Figure 2The mounting frame 7 is also fixedly connected to a traction frame 10, on which a traction ring 11 is provided. The mounting frame 7 can be connected to a traction machine through the traction frame 10 and the traction ring 11, so that the mixing device can be moved by the wheels 4 and dragged.

[0027] See also Figure 3 A motor 12 is fixedly installed at the center of one end of the extension sleeve 3 corresponding to the mixing barrel 2, and a rotating shaft 13 is rotatably installed on the inner side of the mixing barrel 2. One end of the rotating shaft 13 extends out of the mixing barrel 2 and is fixedly connected to the output end of the motor 12. The motor 12 is electrically connected to an external power supply and a switch through a wire, and a stirring arm 14 is symmetrically fixedly connected to the outer side of the rotating shaft 13.

[0028] See also Figure 3 A scraper 15 is fixedly connected to the end of the stirring arm 14 , and the scraper 15 slides in contact with the inner wall of the stirring barrel 2 .

[0029] The motor 12 drives the rotating shaft 13, thereby driving the stirring arm 14 to stir in the mixing barrel 2, so that the concrete is evenly stirred. During the rotation of the stirring arm 14, the scraper 15 is driven to move along the inner wall of the mixing barrel 2, so as to hang on the wall, thereby effectively reducing the amount of concrete sticking to the inner wall of the mixing barrel 2 during discharge, thereby achieving a self-cleaning effect of the barrel.

[0030] See also Figures 4-5 A material guide groove 16 is provided on the outer side of the discharge port 5. The material guide groove 16 is connected to the outer side of the discharge port 5 in a damped rotation manner. After the material guide groove 16 is turned upward, a positioning effect is formed through damping limitation. After the material guide groove 16 is turned downward, the tail end edge of the material guide groove 16 abuts against the bottom surface of the discharge port 5, forming a limiting effect on the material guide groove 16.

[0031] See also Figures 4-5 A slot 17 is provided on the discharge port 5, and a sealing plate 18 matching the slot 17 is slidably connected in the slot 17. The sealing plate 18 extends out of the discharge port 5 and is threadedly connected with a hand bolt 19. A threaded hole for the hand bolt 19 to be threadedly connected is provided on the sealing plate 18. The hand bolt 19 passes through the sealing plate 18 and rests on the front end surface of the mixing barrel 2.

[0032] By tightening and loosening the hand-tightening bolts 19, the sliding of the sealing plate 18 in the slot 17 is controlled, so that the sealing plate 18 can slide up to open the discharge port, thereby discharging the material. At the same time, the discharged concrete is guided away from the equipment by the setting of the guide chute 16 to prevent the concrete from approaching the wheel 4 and causing equipment contamination. At the same time, the guide chute 16 can be rotated and contracted, so that it can be folded during the traction and movement of the equipment to reduce space occupancy.

[0033] The working principle of the utility model is:

[0034] When in use, the mixing device is connected to the traction machinery through the traction frame 10 and the traction ring 11. At this time, the mixing device is placed on the ground through the wheels 4 and the auxiliary wheels 9. At this time, concrete raw materials can be added through the feeding port 6, and the motor 12 is started to drive the mixing arm 14 to rotate through the rotating shaft 13, so as to mix the concrete raw materials, and further rotate the guide chute 16 until the guide chute 16 and the bottom surface of the discharge port 5 form a tight limit. At this time, the hand-tightening bolt 19 is rotated to loosen the fixation of the sealing plate 18, and the sealing plate 18 is further lifted up along the slot 17, and the hand-tightening bolt 19 is rotated to lock the sealing plate 18 to prevent the sealing plate 18 from falling naturally and causing the discharge port 5 to be blocked, so that the concrete in the mixing barrel 2 slides down under the action of gravity and is finally discharged through the discharge port 5. The discharged material falls on the guide chute 16 and is discharged outwardly. During the discharge of the discharge port 5, the mixing arm 14 continues to rotate, so that the mixing arm 14 drives the scraper 15 to clean the inner wall of the mixing barrel 2, reduces the concrete residue on the inner wall, and achieves a self-cleaning effect.

[0035] When it is necessary to change the location, the sealing plate 18 is directly reinserted into the slot 17 to close the discharge port 5, and the guide trough 16 is flipped upward. At this time, the traction machinery tows the mixing device, and the mixing device moves on the construction road through the wheels 4 and the auxiliary wheels 9, so as to move the mixing device to another construction position on the road. At this time, the material can be added through the feeding port 6 again, and stirred by the stirring arm 14, and finally discharged through the discharge port 5 and the guide trough 16 for reuse.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
