Embodiment Construction

[0026] 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. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] Such as figure 2 and image 3 As shown, the pipeline delivery system of the embodiment of the present invention includes a delivery pipeline 1 and a buffer device 2 . The conveying pipeline 1 is used to convey the material in pulse state. The buffer device 2 includes a gas source 21, an air storage tank 22 and a gas delivery pipeline. The gas source 21 is connected to the gas storage tank 22 to supply gas to the gas storage tank 22. The gas delivery pipeline 23 has an air inlet and an air outlet. The air inlet of the gas storage tank 22 is communicated with the outlet of the gas storage tank 22, and the gas outlet of the gas delivery pipeline is communicated with the delivery pipelin...

Abstract

The invention provides a pipeline conveying system, a concrete pump truck and concrete conveying equipment. The pipeline conveying system includes: conveying pipeline, which is used to convey materials in a pulsed state; buffer device, which includes a gas source, a gas storage tank and a gas transmission pipeline, and the gas source is connected to the gas storage tank to supply the gas to the gas storage Tank gas supply, the gas transmission pipeline has an air inlet and an air outlet, the air inlet of the gas transmission pipeline is connected to the outlet of the gas storage tank, and the gas outlet of the gas transmission pipeline is connected to the delivery pipeline for delivery and delivery to the delivery pipeline Airflow in the same direction as the material flow in the pipeline. By applying the technical scheme of the present invention, the buffer device delivers airflow consistent with the flow direction of the material to the conveying pipeline, thereby alleviating the sudden change of pressure in the conveying pipeline and effectively alleviating the problem of shaking.

Description

technical field [0001] The invention relates to the field of construction machinery, and more specifically, to a pipeline conveying system, a concrete pump truck and concrete conveying equipment. Background technique [0002] Such as figure 1 As shown, the existing concrete distributing pump truck is composed of the dismounting assembly 1', the upper body 2', the electrical system 3', the concrete conveying pipe 4', the distributing arm 5', the hydraulic system 6' and the pumping unit 7', etc. , The cooperation of each unit can make the concrete distribution pump truck have the functions of driving, pumping and distribution. [0003] In the process of pumping operation, the concrete distribution pump truck completes the process of absorbing and feeding concrete through the cooperation of the main oil cylinder, concrete cylinder and S valve of the pumping unit 7'. When pouring materials, the concrete is conveyed to the predetermined pouring position through the hopper of th...
