Chain type discharging mechanism of self-dumping tractor-semitrailer

Abstract

The invention relates to a chain type discharging mechanism of a self-dumping tractor-semitrailer. The chain type discharging mechanism comprises a plurality of chains arranged at intervals, a plurality of conveying belts covering the chains are sequentially arranged on the chains, one end of each conveying belt is installed on a belt cross beam, the other end of each conveying belt is a free end,and the belt cross beams are detachably arranged on the chains; a limiting protrusion is arranged at the upper end of an outer chain plate in each chain, a limiting groove matched with the corresponding limiting protrusion is formed in each belt cross beam, each belt cross beam is flatly arranged on the corresponding outer chain plate, and each limiting groove is clamped on the corresponding limiting protrusion; and the limiting protrusions are matched with the limiting grooves to limit the belt cross beams in the horizontal direction, pin shaft installation holes are formed in the limiting protrusions, and pin shafts and pins used for limiting the belt cross beams in the vertical direction are detachably arranged on the pin shaft installation holes. The chain type discharging mechanism has the advantages that the structural design is reasonable, the conveying belts are convenient to disassemble, the chains are convenient to maintain, and the conveying belts are well matched with longitudinal beams.

Description

Technical field: [0001] The invention relates to the technical field of bulk cargo transportation equipment, in particular to a chain-type unloading mechanism of a self-unloading semi-trailer. Background technique: [0002] Dump semi-trailers are mainly used for the transportation of grain, ore, coal, steel and other bulk cargo. Dump semi-trailer mainly includes frame, carriage, rear door and unloading mechanism, etc. The traditional unloading mechanism mainly relies on hydraulic cylinder to lift the whole carriage to turn over to realize unloading. This unloading method has extremely high requirements on hydraulic cylinder, and the whole After the carriage is lifted, the stability is poor, and problems such as hydraulic cylinder explosion, hydraulic cylinder oil leakage, unstable lifting of the carriage, and rollover of the carriage sometimes occur. disuse. The chain-type unloading mechanism is set on the frame at the bottom of the carriage, and relies on the chain and th...

Problems solved by technology

Although the existing chain-type unloading mechanism meets the unloading requirements to a certain extent, it is very inconvenient in the later chain maintenance, because the chain in the chain-type unloading mechanism not only needs to bear the weight of all materials in the compartment (half The load of the trailer is generally between a few tons and dozens of tons) and the material must be dragged to unload in translation, so the pressure and impact on the chain are very large. This special working environment makes the chain vulnerable to damage, so the chain more frequent repairs

Generally, all conveyor belts need to be disassembled during chain maintenance. Each conveyor belt needs about 10 bolts and nuts to be installed on the beam. Generally, more than a dozen conveyor belts are installed on the chain. Each set of chain unloading mechanism generally requires several chains. , so the chain needs to dismantle and install hundreds of bolts and nuts every time it is repaired, and the chain needs to be repaired more often, so the operation of the chain repair is very time-consuming and laborious
