Embodiment Construction

[0027] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0028] Such as figure 1 As shown in FIG. 6 , according to the first embodiment of the present invention, the pumping dispensing mechanism includes a dispensing valve pipe 10 , a rotary gate 20 and a wear disc 30 . The distribution valve tube 10, the rotary gate disc 20 and the wear disc 30 are coaxially arranged along the center of the rotation axis of the distribution valve tube 10. The material is transported from the delivery cylinder to the wear disc 30, and then distributed through the rotary gate disc 20 through the distribution valve tube. 10 pumped into the discharge pipe. The rotary gate 20 is arranged between the distributing valve pipe 10 and the wear-resistant disc 30, and is used to co...

Abstract

The invention provides a pumping distribution mechanism, a pumping device and a control method for the pumping device, and a concrete pump truck. The pumping distribution mechanism comprises a wear-resistant disc (30) provided with n conveying cylinder openings which are uniformly distributed on the circumference, wherein the radian of each conveying cylinder opening is less than or equal to 2 pionic / [n*(n+1)], and n is more than or equal to 3; a distribution valve tube (10) is provided with n+1 distribution valve branch tubes with a common outlet; a rotary brake disc (20) comprises brake disc openings which are respectively formed in each 2 pionic / [n*(n+1)] radian at intervals, and two blades, and the blades shield the conveying cylinder openings when superposed with the conveying cylinder openings of the wear-resistant disc (30); and the inlets of the distribution valve branch tubes, the conveying cylinder openings of the wear-resistant disc (30) and the brake disc openings of the rotary brake disc (20) are in rotary fit. According to the pumping distribution mechanism, pumping impact can be reduced while continuous pumping is realized, and the service life of the pumping distribution mechanism is prolonged.

Description

technical field [0001] The invention relates to the field of pumping, in particular to a pumping distribution mechanism, a pumping device and a control method thereof, and a concrete pump truck. Background technique [0002] Pumping technology is currently the mainstream technology widely used in viscous material transportation construction represented by cement concrete, which has the characteristics of high efficiency and low environmental pollution. Pumping equipment is the core equipment in pumping construction, which is used to transport viscous materials such as concrete in the vertical or horizontal direction. [0003] In the prior art, pumping equipment generally includes a hopper, a conveying cylinder, a distribution valve, a conveying pipe and related driving and control mechanisms. Usually, the pumping equipment has two conveying cylinders on the left and right arranged side by side, the piston is connected with the driving hydraulic cylinder from the rear end of...
