Description

Technical Field

[0001] The utility model relates to the field of concrete mixing, in particular to a concrete mixing device. Background Art

[0002] After the concrete mixing device is mixed, some concrete will adhere to the inner wall of the mixing tank and the stirring paddle. If it is not cleaned for a long time, the concrete will solidify on the inner wall of the mixing tank and the stirring paddle, which will not only increase the resistance when the stirring paddle rotates, but also affect the concrete ratio and thus the effect of the concrete. Therefore, it is necessary to add a cleaning mechanism to clean the mixing device. The current cleaning mechanism generally uses a brush to scrub the inner wall of the mixing tank, and then uses a nozzle to spray the mixing tank to clean the mixing tank and the stirring paddle. This method has a good cleaning effect on the mixing tank. However, the cleaning effect of the stirring paddle is relatively poor when it is only cleaned by spraying.

[0003] CN201820335015 discloses an easy-to-clean concrete mixing device with a detachable brush, comprising a base and a mixing barrel. The top of the mixing barrel is open, and a discharge pipe is connected to the lower right corner of the mixing barrel. The discharge pipe is provided with a valve. A rotating shaft is provided at the axis position of the mixing barrel, and the bottom end of the rotating shaft passes through the bottom wall of the mixing barrel and is rotatably connected to the bottom wall of the mixing barrel. A reduction motor is also fixedly provided at the center of the bottom of the mixing barrel, and the motor shaft at the top of the reduction motor is fixedly connected to the bottom end of the rotating shaft. A plurality of stirring rods are evenly fixedly installed on the left and right sides of the rotating shaft, and the left and right stirring rods are staggered. A spiral blade is fixedly installed at the bottom of the rotating shaft. When cleaning this mixing device, it is necessary to install the plug rod on the stirring rod to clean the inner wall of the mixing barrel. The stirring rod is only cleaned by spraying.

[0004] The technical problem to be solved by the utility model is: how to improve the cleaning effect of the concrete mixing device. Utility Model Content

[0005] The main purpose of the utility model is to provide a concrete mixing device, which can clean the mixing paddle separately by arranging a cleaning bucket. Moreover, by arranging a brush module and a spray module in the cleaning bucket, the mixing paddle can be cleaned more thoroughly, thereby improving the cleaning effect of the mixing device.

[0006] To achieve the above objectives, the technical solutions adopted in this application are:

[0007] A concrete mixing device includes a mixing paddle, a frame, a mixing tank connected to the frame, a cleaning bucket, and a drive unit for driving the mixing paddle to move between the cleaning bucket and the mixing tank; the mixing paddle is rotatably connected to the drive unit; the inner wall of the cleaning bucket is provided with a brush module and a spray module for spraying water onto the mixing paddle;

[0008] After the stirring is completed, the driving unit drives the stirring paddle to move into the cleaning bucket and drives the stirring paddle to rotate around its own axis, so that the stirring paddle and the brush module are in friction contact for cleaning.

[0009] Compared with the existing technology, this solution has the following beneficial effects:

[0010] The concrete mixing device in this case is equipped with a cleaning bucket and a cleaning unit to clean the mixing paddle and mixing tank respectively. The cleaning bucket is equipped with a brush module and a spray module. After the driving unit drives the mixing paddle to move into the cleaning bucket, the driving unit continues to drive the mixing paddle to rotate. At this time, the spray module sprays water on the mixing paddle, causing the concrete on the mixing paddle to initially fall off and soften. During the rotation of the mixing paddle, the mixing paddle and the brush module are in constant contact, allowing the brush module to clean the concrete on the mixing paddle. Through the action of the spray module and the brush module, the concrete on the mixing paddle can be completely cleaned. Moreover, the spray module can not only assist in cleaning the mixing paddle, but also clean the brush module, preventing concrete from sticking to the brush module.

[0011] Secondly, by cleaning the stirring paddle and the stirring tank separately, the cleaning space of the cleaning unit for the stirring tank is increased. Moreover, the stirring paddle can be moved out of the stirring tank, so that the stirring paddle can be cleaned better. BRIEF DESCRIPTION OF THE DRAWINGS
