Before cleaning, the first horizontal section 4311 is pulled outwards to facilitate the movement of the supporting rod 431; the first horizontal section 4311 is pushed inward after cleaning so that the support bar 431 is adjacent to the discharge chute 2.
Referring to fig. 3, the spraying member 44 includes a spraying pipe 441 and a plurality of spraying heads 443. The shower pipe 441 is disposed between the second horizontal sections 4312 at the upper ends of the two support rods 431, and the axis of the shower pipe 441 is parallel to the width direction of the discharge chute 2.
The interior of the shower pipe 441 is provided with a hollow water storage cavity 405, one side of the shower pipe 441 is provided with a connector 4 communicated with the water storage cavity 405, and the connector 4 is connected with the outlet of the liquid discharge pipe 41 to receive the cleaning medium from the liquid storage tank 3. A plurality of through holes are arranged in parallel on the other side of the shower pipe 441, and the nozzles 443 are correspondingly arranged in the through holes one by one. The plurality of nozzles 443 are distributed along the axial direction of the shower pipe 441, and the axial direction of the shower pipe 441 is parallel to the width direction of the discharge chute 2.
And bayonets 403 are disposed at two axial ends of the shower pipe barrel 441 for respectively receiving and fixing the ends of the two second horizontal sections 4312. The spray tube 441 and the second horizontal section 4312 are connected by welding, bolting, snapping, etc. So, can support spraying barrel 441 from both sides respectively through two bracing pieces 431, guarantee the structural stability of spraying barrel 441 in the cleaning process, avoid the concrete thick liquid to splash outside the feeder hopper, guaranteed the cleanliness factor of churn in the cleaning process.
As shown in fig. 4, the side wall of the discharge chute 2 is provided with a limiting hole 203. The vertical section 4313 is provided with a through hole 401 corresponding to the limiting hole 203 in a matching manner, so that the support rod 431 is fixed on the side wall of the discharge chute 2 when being collected in the side wall.
In the using process, the two support rods 431 rotate respectively to drive the support frame 43 to swing backwards relative to the discharge chute 2 integrally, and the support frame is unfolded and stands on the discharge chute 2, so that the spraying piece 44 can be conveniently aligned to the discharge chute 2 downwards. After cleaning, the supporting rod 431 swings forward relative to the discharging chute 2 until swinging to a certain angle, so as to be folded and attached to the side wall of the discharging chute 2. At this moment, the via hole 401 on the bracing piece 431 and the spacing hole 203 on the blowpit 2 are correspondingly conducted, and the spacing pin through the adaptation is penetrated through the spacing hole 203 and the via hole 401 to lock the support frame 43 on the blowpit 2, realize accomodating of support frame 43.
It should be noted that, because the support frame 43 can rotate relative to the discharge chute 2, the spray piece 44 is driven by the support frame 43 to rotate in a reciprocating manner, so that the hopper of the mixer truck can be further cleaned sufficiently while the mixer drum is cleaned, and the cleaning effect is better.
The discharge chute 2 is used for guiding the concrete slurry flowing out of the discharge port 201 of the mixing drum, and the width of the discharge chute is smaller than the maximum caliber of the feed hopper of the mixing truck. Since the support bracket 43 is mounted on the discharge chute 2, the support bracket 43 should be offset from the discharge chute 2 by a predetermined distance, which is determined so that the shower pipes 441 on the support bracket 43 can sufficiently act on the hopper.
Before use, the position of the discharge chute 2 is adjusted, so that the higher end of the discharge chute 2 is positioned right below the mixing drum discharge port 201, and the spray head 443 of the spray pipe barrel 441 is positioned right above the mixing drum hopper. After the lift pump 412 is activated, the lift pump 412 pumps the cleaning medium in the tank 3 into the spray pipe 441 through the drain pipe 41, and sprays the cleaning medium into the hopper through the spray pipe 441. The cleaning medium can wash the hopper (arranged at the tail end of the mixing truck barrel), so that the cleanliness of the hopper is maintained. The washed cleaning medium can enter the mixing drum through the discharge port 201 of the hopper. The power device on the mixer truck drives the mixing drum to rotate, and the inner wall of the mixing drum is automatically cleaned in the rotating process of the mixing drum. The concrete slurry produced during the cleaning process flows out through the inlet and outlet 201 of the mixing drum.

The follower 53 is drivingly connected to a first horizontal section 4311 of a support rod 431. The driving motor 51 is fixedly installed on the discharging chute 2. The output end of the driving motor 51 is connected with a driving wheel 52 for driving the supporting rod 431 to rotate so as to adjust the angle between the supporting rod 431 and the discharging chute 2. During the cleaning process, the rotation direction of the rotating shaft of the driving motor 51 can be changed to change the angle of the spraying pipe barrel 441 relative to the hopper, so that the hopper can be fully cleaned. In order to avoid interference between the driving motor 51 and the support rod 431 during storage, the driving motor 51 is preferably installed at the bottom of the discharge chute 2. It should be noted that when the rotary drive unit is provided, a separate positioning mechanism is not required to ensure that the shower pipe 441 and the hopper of the mixer truck are relatively stationary during the cleaning process.
