Description

Technical Field

[0001] The utility model relates to concrete Background Art

[0002] At present, in the process of asphalt concrete production, hot materials and cold materials need to be put into the mixing drum for mixing. In order to prevent the asphalt raw materials and cold materials from being mixed and melted unevenly in the mixing drum, which affects the viscosity of the asphalt, the cold materials are generally heated in the heating drum, and then mixed with the hot materials. The cold concrete materials need to be transported to the designated project site through the concrete cold material loading device for loading and use.

[0003] The existing asphalt concrete cold material feeding structure is achieved by installing an adjustment mechanism at the upper end of the device body, installing an inner extension column at the upper end of the machine table, and installing a connecting column at the lower end of the feeding barrel. The connecting column is flexibly connected to the upper end of the inner extension column through a tension spring. The height of the feeding barrel is adjusted by the connecting column, and the angle of the rotating shaft limit material box is adjusted, thereby driving the height of the discharge port to be adjusted. By inserting the bolt in the bolt groove, the height of the connecting column after adjustment is fixed, thereby realizing rapid angle adjustment.

[0004] However, since the loading barrel is relatively large and long, it is laborious and inconvenient to operate to manually adjust the height of the connecting barrel column and fix it with bolts. Utility Model Content

DETAILED DESCRIPTION

[0031] In order to make those skilled in the art better understand the present invention, the present invention is further explained in detail below with reference to the accompanying drawings and embodiments. It should be noted that the features in the embodiments and embodiments of the present application can be combined with each other without conflict.

[0032] A typical embodiment of the utility model provides a concrete cold material feeding device, such as Figure 1 As shown, it includes a machine platform 2, a feeding structure 8 and a loading barrel 1.

[0033] The feeding mechanism 8 is rotatably connected to the machine platform 2 through a mounting seat, and the main body of the feeding structure 8 is a feeding hopper. The feeding barrel 1 has a feeding channel inside, and the feeding barrel 1 is connected to the feeding mechanism 8. The feeding mechanism 8 is used to pour the cold concrete into the device, and the feeding barrel 1 is used to transport the cold concrete in the feeding mechanism 8 to a designated position.

[0034] On this basis, if Figure 1 , Figure 2 As shown, in this embodiment, an adjusting assembly 3 for adjusting the inclination of the loading barrel is provided. The adjusting assembly 3 comprises a motor 31 , a shaft 32 , a gear 33 and an arc-shaped rack 34 .

[0035] The motor 31 is disposed on the outer wall of the loading barrel 1 and is electrically connected to an external power source. One end of the shaft 32 is connected to the rotating shaft of the motor 31. The gear 33 is fixedly sleeved on the outer wall of the other end of the shaft 32. The bottom end of the arc-shaped rack 34 is fixedly connected to the upper surface of the machine table 2, and the gear 33 is meshed with the arc-shaped rack 34.

[0036] According to the above embodiment, when it is necessary to adjust the height of the discharge port of the loading barrel 1, start the motor 31, and the rotating shaft of the motor 31 drives the shaft body 32 to rotate, and the shaft body 32 drives the gear 33 sleeved on its outer wall to rotate. When the gear 33 rotates, it is in a meshing state with the arc-shaped rack 34. The gear 33 rotates and moves on the arc-shaped rack 34. When the gear 33 moves, it drives the loading barrel 1 and the feeding mechanism 8 to rotate relative to the machine table 2. The height of the discharge port on the loading barrel 1 is changed by adjusting the inclination of the loading barrel 1. When the height of the discharge port on the loading barrel 1 reaches a suitable height, the motor 31 can be turned off.

[0037] like Figure 3 , 4 As shown, based on the above structure, a preferred embodiment of the present invention is provided with a limit assembly 4. The limit assembly 4 includes a tank body 41, a slider 42, an arc-shaped slide rail 43 and a rod body 44.

[0038] The tube body 41 is bearing-connected to the outer wall of the shaft body 32. One end of the slider 42 is connected to the outer wall of the tube body 41. The bottom end of the arc-shaped slide rail 43 is fixedly connected to the upper surface of the machine table 2, and the other end of the slider 42 is slidably connected to the arc-shaped slide rail 43. The two ends of the rod body 44 are respectively connected to the top of the arc-shaped slide rail 43 and the arc-shaped rack 34.

[0039] According to this embodiment, when the shaft body 32 moves, it drives the slider 42 on the tube body 41 to slide in the arc-shaped slide rail 43, and the rod body 44 serves as a connecting member to maintain the relative stability of the arc-shaped slide rail 43 and the arc-shaped rack 34. The arc-shaped slide rail 43 limits the gear 33 and prevents the gear 33 from being separated from the arc-shaped rack 34. One end of the slider 42 that is slidably connected to the inner side wall of the arc-shaped slide rail 43 is a smooth arc surface, so that the slider 42 slides more smoothly in the arc-shaped slide rail 43.

[0041] One end of the clamping rod 5 is detachably connected to one end of the shaft 32 away from the motor 31 . Specifically, one end of the clamping rod 5 is hinged to the shaft 32 via a pin.

[0042] The block 6 is fixedly arranged on the outer wall of the upper barrel 1, and a clamping ring 7 matching the clamping rod 5 is arranged on the surface of the block 6. The clamping rod 5 is clamped on the clamping ring 7. By rotating the clamping rod 5 and engaging it with the clamping ring 7, the stability of the upper barrel 1 after height adjustment will be further enhanced.

[0043] The cross section of the clamping rod 5 is fan-shaped, which facilitates the clamping rod 5 to be clamped with the clamping ring 7. A plate 9 is provided at one end of the clamping rod 5 away from the shaft 32, and the plate 9 abuts against the outer wall of the clamping ring 7 to increase the stability of the clamping rod 5 when clamping with the clamping ring 7.
