Dynamic automatic weighing system for kitchen garbage truck

Abstract

The invention discloses a dynamic automatic weighing system of a kitchen garbage vehicle. The dynamic automatic weighing system comprises a lifting track, a turnover mechanism, a lifting rack, a weighing mechanism, a pressure compensation mechanism and a data control device; and the lifting track is assembled on a garbage vehicle body, the turnover mechanism can longitudinally be turned over and movably installed on the lifting track in the vertical direction, the lifting track is fixedly installed on the turnover mechanism, the weighing mechanism is movably installed on the lifting rack in the vertical direction, the upper end of the turnover mechanism is provided with the pressure compensation mechanism, the barrel pressing force compensation mechanism comprises a barrel pressing force compensation sensor, a force transmission connector and a barrel pressing plate, the barrel pressing plate is connected below the barrel pressing force compensation sensor through the force transmission connector, signals of the weighing mechanism and the barrel pressing force compensation mechanism are output to the data control device, and then garbage weight operation is performed. The system needs no manual operation in the whole process, is provided with the dynamic weighing barrel pressing force compensation structure, satisfies a good dynamic weighing performance requirement, and has the advantage of high weighing precision.

Description

technical field [0001] The invention relates to the technical field of sanitation equipment, in particular to a dynamic automatic weighing system for a kitchen garbage truck. Background technique [0002] At present, various cities in China have strengthened law enforcement on the management of food waste, and incorporated the recycling, transportation, and disposal of food waste into the normal supervision of the environmental protection department. Kitchen garbage trucks usually need to weigh the garbage in the garbage bin before loading. The electronic scale of the kitchen garbage truck in the prior art is used in conjunction with the hanging bucket lifting frame and the turning frame in the vehicle loading mechanism. After the garbage can is mounted, it is lifted to withstand the top plate of the turning frame and performs static or dynamic measurement during the rising process. Because the top plate of the turning mechanism presses the edge of the trash can, it will in...

Problems solved by technology

In this structure, when the hanging teeth hang on the garbage can, the pressure plate will produce a slight deformation, and the resistance strain sensor collects the deformation data of the pressure plate and converts it into an electrical signal to obtain the measured value. However, when the lifting device drives the garbage When dynamic weighing is carried out during the moving process of the barrel, the lifting frame is affected by frictional resistance and other forces, resulting in deviations in the weighing value. Due to the lack of dynamic performance compensation design for weighing pressure, it does not have good dynamic weighing performance. poor accuracy
