Embodiment Construction

[0037] In the prior art, the control of the paver hopper needs to be carried out according to the results of human visual inspection by the operator, resulting in poor operation accuracy and reliability, and the frequent operation of the paver hopper switch also increases the labor intensity of the operator problem, the embodiment of the present invention provides a paver hopper control method, which uses a rangefinder to automatically measure the distance between the material truck and the paver, and automatically controls the opening and closing of the paver hopper according to the measurement results, thereby improving The precision and reliability of paver hopper control, and reduce the labor intensity of the operator.

[0038] Such as figure 1 As shown, a hopper control system for a paver provided in an embodiment of the present invention includes:

[0039] The opening valve 1011 for controlling the opening of the paver hopper and the closing valve 1012 for controlling t...

Abstract

The invention relates to the field of engineering machinery, provides a control technique of a spreading machine hopper, and is used for automatically controlling the spreading machine hopper. The embodiment of the invention provides the following technical schemes: a control system of the spreading machine hopper comprises a valve used for controlling the hopper to open and another valve used for controlling the hopper to close, as well as a range finder and a controller, wherein the range finder is arranged on a spreading machine and is used for measuring the distance between a skip car and the setting position of the spreading machine; and the controller is connected with control loops of the two valves and the range finder respectively, and is used for controlling the valve for opening to have electric action to open the spreading machine hopper when determining that the distance between the skip car and the setting position of the spreading machine is gradually reduced and is smaller than or equal to a set first distance threshold value according to the measured result of the range finder, or controlling the valve for closing to have electric action to close the spreading machine hopper when determining that the distance between the skip car and the setting position of the spreading machine is gradually increased and is larger than or equal to a set second distance threshold value, and the stock level is smaller than or equal to a set height threshold value.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a control technology for a paver hopper. Background technique [0002] Construction machinery is a general term for the mechanical equipment necessary for comprehensive mechanized construction projects required for earthwork construction projects, road surface construction and maintenance, mobile lifting and loading and unloading operations, and various construction projects. Mainly used in national defense construction projects, transportation construction, energy industry construction and production, mining and other raw material industry construction and production, agriculture, forestry and water conservancy construction, industrial and civil construction, urban construction, environmental protection and other fields. [0003] Paver is a kind of construction equipment mainly used for paving various materials on the base course and surface course of the expressway. The ty...
