Embodiment 1

[0029] Such as figure 1 As shown, a raw material mixing equipment for road and bridge construction includes: a mixing drum 1 with an arc surface at the bottom, a stirring mechanism 2 and a driven mechanism 4, and the top of the mixing drum 1 is hollow; the mixing mechanism 2 is arranged on the mixing drum 1 On the top, it includes: a drive gear 21 driven by an external motor, a first transmission wheel 22 that is coaxial with the drive gear 21 and rotates synchronously, a second transmission wheel 23 that is symmetrically arranged with the second transmission wheel 22, and is sleeved on the The drive belt 24 on the first transmission wheel 22 and the second transmission wheel 23, the rocking bar 25 with one end arranged on the second transmission wheel 23, and the stopper with one end arranged on the drive gear 21 through the runner 221 Arm 27, the stirring arm 26 that is connected on the other end of described limiting arm 27, the stirring head 3 that is arranged on the other...

Embodiment 2

[0042] The difference from Example 1 is:

[0043] Such as image 3 As shown, in order to improve the mixing effect of raw materials in the mixing drum 1, the support member 51 includes: a first support plate 511, a second support plate 512, a first telescopic rod 513 and a rotating shaft 514, and the first support plate 511 is arranged on the Below the mixing drum 1; the second support plate 512 is arranged below the first support plate 511; the first telescopic rod 513 is arranged between the first support plate 511 and one end of the second support plate 512, and the other One end is connected by a rotating shaft 514, and the first telescopic rod 513 is controlled by an external controller, which is an electric telescopic rod. The inclination of the first support plate 511 is changed through the first telescopic rod 513, and the rotation state of the mixing drum 1 is changed, thereby improving Mixing effect of raw materials.

Abstract

The invention discloses raw material mixing equipment for road and bridge construction. The raw material mixing equipment comprises a stirring cylinder, a stirring mechanism and a driven mechanism, wherein the stirring mechanism comprises a driving gear, a first transmission wheel, a second transmission wheel, a transmission belt, a rocking bar, a limiting arm, a stirring arm and a stirring head; the stirring head is positioned in the stirring cylinder; one end of the rocking bar is arranged on the stirring arm; the driven mechanism comprises a driven wheel; a water supply mechanism absorbs water through the driven mechanism and sprays water into the stirring cylinder; one end of the water supply mechanism is used for providing a water source for the stirring cylinder, and a piston rod is arranged at the other end of the water supply mechanism in a penetrating manner; one end, positioned outside the stirring cylinder, of the piston rod is connected with a connecting arm; the other end of the connecting arm is connected to a position, deviating from the center of a circle, on the driven wheel. According to the raw material mixing equipment disclosed by the invention, the stirring mechanism is matched with the water supply mechanism, so that water is added at a neutral position generated in the stirring cylinder by stirring and overturning, the water and raw materials are in more sufficient contact and mixing, and the phenomena that the raw materials are solidified and inconvenient to stir due to poor water quantity control are prevented.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a raw material mixing equipment for road and bridge construction. Background technique [0002] Road bridges are generally composed of several parts such as roadbed, road surface, bridge, tunnel engineering and traffic engineering facilities. [0003] The main materials for building roads and bridges are asphalt, cement and concrete. When preparing cement, a mixing device is needed to mix the proportioned aggregate, cement powder and other raw materials. However, when mixing the raw materials, water is prone to occur. The small addition will cause the stirring to solidify, so it is necessary to continuously add water during stirring to prevent the cement from solidifying. [0004] The current mixing device is easy to cause the cement to solidify, because it can only stir the cement raw materials, resulting in uneven mixing, and the bottom or unstirred area i...
