Screw distributing system, control equipment, method and engineering mechanical equipment

Abstract

A spiral material distribution system comprises a spiral drive apparatus (1), a material distribution screw rod (2), a spreading groove (3) and a control device. The material distribution screw rod (2) is positioned in the spreading groove (3) and is driven by the spiral drive apparatus (1) to rotate. The control device comprises a receiving apparatus (10) and a controller (20). The controller (20) is connected to the receiving apparatus (10) and the spiral drive apparatus (1), and compares a detected material level value with a preset material level value, so as to control running of the spiral drive apparatus (1). Also provided are a method for controlling the spiral material distribution system and an engineering mechanical device configured with the spiral material distribution system. According to different material level situations, the control device controls, in different manners, the spiral drive apparatus (1) to work, so that a material is spread evenly.

Description

technical field [0001] The present invention relates to the field of construction machinery, in particular to a spiral material distribution system, control equipment, method and construction machinery equipment. Background technique [0002] figure 1 Schematic diagram of the structure of the spiral cloth system. Such as figure 1 As shown, the system includes a screw driving device 1, a distributing screw 2 and a spreading tank 3, the distributing screw 2 is located in the spreading tank 3, and is driven by the screw driving device 1 (the screw rotating device 1 can Including hydraulic motor and reducer) to drive the rotation. Note that this figure only shows the structure of an auger distribution system located on the left side of the paver. The right spiral cloth system is much the same. The screw driving device 1 drives the distribution screw 2 to rotate, and the material conveyed by the scraper to the system can be conveyed to the paving width through a spiral relay...

AI Technical Summary

Problems solved by technology

[0004] However, in the actual construction process, due to various reasons, it often occurs that there is too much material at the end of the paving groove instead of too little material at the end

In this case, the material level detection device can only detect the material level of the end material, and the system cannot make corresponding control for the lack of non-end material. At this time, the material can only be replenished manually
