Preferably, the two groups of helical blades are arranged in a forward and reverse rotation mode.

Preferably, a loading and unloading hopper is arranged on one side, close to the buffer mechanism, of the bearing shell and the material rolling barrel.

Preferably, the total length of the roller bucket is less than the total length of the load bearing housing.

Preferably, the water gun head, the water pump and the water tank are connected through a water pipe.

The invention has the beneficial effects that:

1. the helical blade who adopts positive and negative rotation to set up in the device can control the process of stirring and unloading respectively through two kinds of rotations, can guarantee simultaneously through the buffer gear who sets up in the transportation, can not lead to the unrestrained of concrete because jolting, and also avoided long-term the use because jolt the damage that leads to certain part of device.

2. Need abluent process after the transportation driver unloads the material, need not wash through the mode of filling water again, after unloading the material, the transportation driver opens the water pump and draws the water branch to the material rolling bucket in the in-process of returning journey, and the direction stirring begins simultaneously, has avoided the solidification of concrete, has also washd inside the material rolling bucket, and save time is also convenient quick.

The invention has the advantages that the buffer mechanism is arranged, the scattering of the loading materials in the transportation process is avoided, the device in long-term use is also protected, the cleaning process can be carried out on the way of return in the cleaning process, the time for transporting a driver is saved, the solidification of the residual concrete in the barrel is also avoided, and the practicability is high.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below.

The stirring device for the concrete mixer comprises a self-contained car body 1, wherein a bearing shell 11 is arranged on the upper surface of the self-contained car body 1, a buffer mechanism 2 is fixedly connected to the lower end of one side of the bearing shell 11, roller tracks 6 are fixedly arranged on the inner wall of the bearing shell 11 in a symmetrical distribution manner, the bottom end of the buffer mechanism 2 is fixedly arranged on one side of the upper surface of the self-contained car body 1, a rolling barrel 3 is arranged inside the bearing shell 11, spiral blades 10 are symmetrically welded inside the rolling barrel 3 along the central axis direction, a roller slide 9 matched with the roller tracks 6 is fixedly arranged on the outer wall of the rolling barrel 3, a transmission mechanism 12 is fixedly arranged on one side of the upper surface of the self-contained car body 1, a fixed support 15 is fixedly arranged at the top end of the transmission mechanism 12, a servo motor 13 is fixedly arranged inside the fixed support 15, a rotary rod 14 is fixedly arranged, and the top fixed connection of rotary rod 14 is in the bottom of roller bucket 3, the lower fixed surface of full-package automobile body 1 installs water tank 4, and the upper fixed surface of full-package automobile body 1 installs water pump 5, the one end inner wall fixed mounting of bearing casing 11 has a water gun head 8, two sets of helical blade 10 are the setting of positive and negative rotation mode, bearing casing 11 is provided with loading and unloading hopper 7 with one side that is close to buffer gear 2 of roller bucket 3, the total length of roller bucket 3 is less than the total length of bearing casing 11, water gun head 8 and water pump 5, water pump 5 and water tank 4 all lead to pipe connection.
