Stock bin weighing device

Abstract

The invention relates to a stock bin weighing device. The upper end and the lower end of a column type weighing sensor are provided with a bearing head and a connecting head respectively, external threads are formed on the bearing head and the connecting head, the bearing head is in threaded connection with an upper flange plate, a bearing table is connected at the upper end of the upper flange plate, the upper end of the bearing table is provided with a retractable locating step, the connecting head is in threaded connection with a lower flange plate, a supporting seat is connected with the lower end of the lower flange plate, the bottom surface of the supporting seat is oblique relative to the horizontal plane, and a tubular landing leg at the bottom of the stock bin is arranged on the locating step of the bearing table in a sleeved mode for welding on site conveniently, therefore, the aesthetic degree and the connecting strength are improved; the bottom surface of the supporting seat is seated on the ground of the installation site, the stressed axis of the column type weighing sensor in the weighing device is coincided with the stressed direction of the landing leg, so that the influence of lateral force caused by inconsistence of the stressed direction of the tubular landing leg and the weighing sensor is eliminated; and the column type weighing sensor and the upper flange plate or the lower flange plate rotate oppositely, therefore, a distance between the upper flange plate and the lower flange plate can be accurately and conveniently adjusted.

Description

technical field [0001] The invention relates to a weighing device, in particular to a weighing device for a silo. Background technique [0002] At present, the weighing of various silos is mostly completed by weighing sensors. For example, the weighing of the dry-mixed mortar mobile silo is currently used to install a weighing device with a load cell at the bottom of the dry-mixed mortar mobile silo. , the basic structure of an existing dry-mixed mortar mobile bin weighing device is as follows: it has a column-type load cell, the upper and lower ends of the column-type load cell are respectively provided with a load-bearing head and a connecting head, and the load-bearing head is connected to a For the butt-joint semicircular upper flange connection, after a pair of flanges are butted, the stepped notch of the two is butted to form a stepped blind hole, and the bearing head is located in the stepped hole blind; the connecting head is threadedly connected with a support seat ...

AI Technical Summary

Problems solved by technology

Therefore, the shortcomings of the above-mentioned weighing device are: it is inconvenient to adjust and correct; during the transfer process of the dry-mixed mortar mobile bin from the transport vehicle, due to the bumps in the transportation, the calibrated sensor is prone to move, resulting in It needs to be adjusted and corrected in the next installation, which increases the difficulty of adjustment and affects the measurement accuracy of the sensor
