Design scheme of concrete distributor

Sweeper is the patented head of belt conveyor, which is designed for the special requirements of conveying concrete cleaning mortar. The scraper adopts cemented carbide with rectangular cross section, which is wear-resistant and does not hurt the adhesive tape, and the mortar loss is small. The belt feeder is designed as a hinged structure with two light trusses, the upper end of which is hinged on the rotating hopper on the frame, and the angle between the two trusses is adjusted according to the needs through the hinged oil cylinder; A universal wheel is designed at the lower part of the belt conveyor, which can move along the truss axis under the drive of the oil cylinder and adjust the height of the belt tail.

With this design, the cloth feeder can walk on the tail without disassembly, and can also be mounted on the cloth feeder without disassembly. The loading and unloading of the feeding tape machine is completed by the cloth machine itself, and auxiliary equipment such as cranes are not needed. Belt conveyor supported by four telescopic trusses The belt conveyor is designed as a single telescopic (multi-section) belt conveyor supported by four telescopic trusses, which is linked by steel wires, driven by friction wheels and guided by eccentric slideways. The adhesive tape is wound by reversing rollers in multiple layers, and the lap length can automatically change with the lap length of the truss during expansion and contraction, so that the total length of the adhesive tape remains unchanged; Eccentric slideway can ensure the accurate alignment of truss during expansion and contraction.

The imported cloth machine (tire belt machine) is based on heavy trucks or off-road tire cranes. The patent of distributor adopts self-propelled crawler crane as chassis, forming the structure of articulated belt feeder+crawler chassis+telescopic belt feeder, which is the first in China. This innovative design has created a road for the localization of the belt loom and is the main protection content of the loom patent. This design is mainly based on two considerations: first, there is no large-scale off-road tire crane product in China at present, so it is impossible to produce tire chassis distributor (tire belt conveyor), but there is a mature 50 ~ 80t crawler crane chassis in China; Secondly, the chassis of crawler crane has good working stability, and it can be put into work immediately without additional legs on the ground with a slope less than 4, so it has good maneuverability.
