Abstract

The invention discloses a buffer scale based on hydraulic buffering. The buffer scale comprises an upper scale body, a lower scale body and pre-warning bolts. The upper scale body comprises a plurality of upper ring center discs, and the lower scale body comprises a plurality of single-rod single-item type piston cylinders and lower ring center discs. Piston rods of the single-rod single-item type piston cylinders are connected with the upper ring center plates and the lower ring center plates in a clearance fit mode. The lower scale body further comprises a sealed shell, a fluid channel, an elastic piston assembly, a pressure sensor, an outer frame and the like. A spring buffering structure is replaced with a hydraulic buffering system structure. In the weighing process, impact of non-constant speed and non-constant mass objects can be effectively and rapidly absorbed through hydraulic oil to achieve primary buffering, secondary buffering is achieved through the elastic small change of a channel elastic piston assembly unit, buffering time is shortened, the weighing weight is increased, and the weighing adaptability in a complex working environment is improved.

Description

technical field [0001] The invention relates to a buffer scale based on hydraulic buffer, which belongs to the technical field of buffer scale equipment. Background technique [0002] Electronic weighing technology is one of the important foundations of modern weighing measurement and control system engineering. Since the infiltration of electronic technology into the auxiliary measuring device of weighing instruments in the mid-1950s, and the appearance of electromechanical electronic weighing instruments in the early 1960s, it has been continuously improved for more than 40 years. With the improvement and improvement, the electronic weighing apparatus has developed from the original electromechanical combination type to the current all-electronic type and digital intelligent type. In recent years, with the rapid development of computer and weighing sensor technology and the mutual penetration of modern science and technology, electronic weighing technology and its applicat...
