Through the cooperation of the image sensor and the tracker 51, the tracking mark 53 on the distributing vehicle 30 is tracked, the first rotary driving mechanism 19 and the second rotary driving mechanism 20 on the distributing machine 10 are controlled, and the synchronous tracking and following of the discharging end of the distributing machine 10 and the position of the distributing vehicle 30 are realized.
According to the concrete distributing device 100 of the embodiment of the application, the distributing truck 30 is connected with the distributing machine 10 through the flexible connecting pipe, so that the impact force of concrete conveying is reduced, the movement deviation of the distributing machine 10 in the following process is compensated, the swinging and vibrating force of the conveying pipe in the concrete pumping process of the distributing machine 10 is ensured not to be transmitted to the distributing truck 30, and the accurate movement control of the distributing truck 30 is not influenced. The secondary feeding of the distributing vehicle 30 avoids the pulse caused by direct distributing of the concrete pumping equipment, distributing is realized through the movement of the distributing vehicle 30 and the stretching and swinging of the distributing pipe 35, and the distributing precision is improved. This concrete distributing device 100 has saved the manpower, has reduced intensity of labour, is convenient for realize the automatic accurate cloth of concrete.
It should be noted that the features of the embodiments in the present application may be combined with each other without conflict.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
