Embodiment 1

[0029] Such as figure 1 , an attached rotary sealed mixer truck, comprising a mixing bucket 1 and a sealing cover 3 located at the rear side of the mixing bucket 1 , the mixing bucket 1 is connected to the mixing bucket 1 through a rotary sealing device 2 .

[0030] Such as Figure 4 , the specific structure of the rotary sealing device 2 is: the rear end of the mixing bucket 1 is provided with a ring rail 2-3, and the inner edge of the ring rail 2-3 is connected to the rear end of the mixing bucket 1, The ring rail 2-3 is located on the front side of the sealing cover 3.

[0031] The front end of the sealing cover 3 is provided with a connecting ring 2-2 sleeved on the outside of the ring rail 2-3, and the sealing cover 3 and the connecting ring 2-2 are directly provided with a sealing gasket 2-4. The front end of the connecting ring 2-2 is equipped with a fixed ring 2-1 located at the front side of the ring rail 2-3. The fixed ring 2-1 is a split type, which is spliced ​​...

Embodiment 2

[0046] Such as figure 2 and 3 , the difference between this embodiment and Embodiment 1 is:

[0047] The bottom plate 5 is also installed at the inlet and outlet, which is composed of hard side plates, hard plates and soft side plates, and can also be made of integral hard or soft materials. The base plate 5 is manually switched, or its opening and closing is controlled by an opening and closing control mechanism.

[0048] The specific structure of the opening and closing control mechanism is: the base plate 5 is hingedly installed at the inlet and outlet; the opening and closing control structure includes a telescopic cylinder 6, and the telescopic rod is an oil cylinder or an air cylinder. The sealing cover 3 is rotatably connected, and the other end is rotatably connected with the bottom plate 5 .

[0049] When feeding or discharging, bottom plate 5 is opened. When transporting, the bottom plate 5 is closed to prevent the material from spraying out during transport.

Abstract

The invention discloses an attaching body type revolution sealing agitation vehicle. The agitation vehicle comprises an agitation barrel and a sealing cover located on the rear side of the agitation barrel. The sealing cover is connected with the agitation barrel through the revolution sealing device. The agitation vehicle further comprises a stop mechanism used for stopping the sealing cover fromrotating along with the agitation barrel. When the stop mechanism is locked, the sealing cover is static relative to a vehicle body of the agitation vehicle. When the stop mechanism is released, thesealing cover revolves along with the agitation barrel under the effect of the revolution sealing device. A feeding and discharging mechanism is installed on the sealing cover. When a feeding and discharging opening of the feeding and discharging mechanism is upward, the feeding and discharging opening is used as a feeding opening. When the feeding and discharging opening is downward, the feedingand discharging opening is used as a discharging opening. According to the sealing agitation vehicle, the sealing cover is connected with the agitation barrel through the revolution sealing device, the sealing cover is provided with the feeding and discharging mechanism combining feeding and discharging, the structure is simplified, the weight is reduced, and the agitation vehicle further has theadvantages of being convenient to maintain, reducing scattering and leaking and the like.

Description

technical field [0001] The invention relates to a rotary sealing device for a ready-mixed concrete mixer truck, which can also be used on dry and wet material trucks for other fluids. Background technique [0002] The mixing barrel of the traditional concrete mixer truck is mainly open, which has problems such as poor heat preservation and moisture retention, easy spillage, and poor concrete quality. In order to solve the above problems, the existing mixer truck has a sealing cover added at the end of the mixing tank, and the sealing between the mixing tank and the sealing cover is realized by a rotary sealing device and supported by a rotary support device. [0003] The existing mixer trucks have the following problems: the tail includes mechanisms such as rotary seals, rotary supports, feed hoppers, and discharge ports, and the structure is complex and heavy. Contents of the invention [0004] The invention proposes a body-attached rotary sealed mixer truck, the purpose...
