Embodiment 1

[0025] Such as figure 1 with figure 2 As shown, it is a rotary automatic centering device for a mining mixer truck, including a car body bracket 212, an inner ring used to connect to the mixing drum 109, and a cover arranged on the inner ring and rotatably connected with the circumferential outer wall of the inner ring The feeding and discharging unit 200 also includes a floating self-aligning structure, one end of the floating self-aligning structure is flexibly connected to the feeding and discharging unit 200, and the other end is connected to the car body bracket 212; the feeding and discharging unit 200 includes an outer ring 102 and a sealed tail cover 103 ( In the figure, the inner ring is covered by the sealing end cap 103, so the inner ring is not shown), the circumferential inner wall of the outer ring 102 is rotationally connected with the circumferential outer wall of the inner ring, and the sealing end cap 103 is connected to the outer ring by circumferentially d...

Embodiment 2

[0030] The present embodiment is similar to embodiment 1, and its difference is:

[0031] In this example, if Figure 4 As shown, the floating self-aligning structure is an elastic compensating assembly 207 respectively connected to the two sides of the outer ring 102 close to the end of the vehicle body bracket 212; Figure 5 As shown, the elastic compensation assembly 207 includes a support bracket 208, a reset device 209 and a support 210. The support bracket 208 is connected to the circumferential outer wall of the outer ring 102, the support 210 is installed on the vehicle body bracket 212, and one end of the reset device 209 is connected to the support Holder 208, the other end is connected to support 210; Reset device 209 is a stainless steel spring; In this embodiment, one side of sealing tail cap 103 is also connected with outer ring 102 by hinge 211, is convenient to open sealing tail cap 103, replaces seal .

[0032] As an alternative, the elastic compensating ass...

Abstract

The invention provides a mining mixer truck rotation automatic aligning device. The mining mixer truck rotation automatic aligning device comprises a truck body support, an inner ring used for being connected to a mixing drum, a feeding and discharging unit arranged on the inner ring in a covering mode and rotationally connected with the circumferential outer wall of the inner ring, and a floatingaligning structure, wherein one end of the floating aligning structure is flexibly connected with the feeding and discharging unit, and the other end of the floating aligning structure is connected to the truck body support. According to mining mixer truck rotation automatic aligning device, due to the action of an floating aligning assembly, the floating aligning assembly can float up and down,front and back and left and right within a certain range for compensation, so that the feeding and discharging unit can move along with the inner ring, an outer ring does not excessively restrain theinner ring, and the inner ring and the outer ring do not suppress force, so that the outer ring and the inner ring are prevented from generating abnormal sound and even damaging the rotary device dueto excessive attachment and excessive friction, therefore the whole rotary device can be protected, operation safety is guaranteed, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the field of mixer trucks, in particular to a rotary automatic centering device for mine mixer trucks. Background technique [0002] Mine mixer truck is a kind of mixer truck used in mines and tunnels. The feed port and discharge mechanism (discharge port and discharge cylinder for opening the discharge mechanism) of the existing mixer truck are integrated in the mixing At the same time, the tail cover is used to seal the tank body of the mixer truck to prevent the tank from being exposed, causing the material liquid to evaporate or be exposed; the inner ring is connected to the mixing drum of the tank body through bolts, and follows the mixing drum Rotate together, as a whole on the moving side; the tail cover is connected to the outer ring to form a static side as a whole, thus forming a rotary seal; there will be a gap between the end cover and the inner ring, and the sealing of the inlet and outlet mainly depends on the inn...
