Specific embodiment
As shown in the figure.A kind of mechanical scale correcting apparatus, including load cell 1, position-limit mechanism and scale correcting apparatus 4, it is described
Load cell 1 is connected to 4 top of scale correcting apparatus, and position-limit mechanism is set to the top of load cell 1, and the scale correcting apparatus 4 is put
In feed bin ear mount 3, bunker scale weighing sensor 2 is provided with below the feed bin ear mount 3, the scale correcting apparatus 4, which drives, to be surveyed
The rising of force snesor 1 withstands position-limit mechanism and is locked by locked mechanism 6, and the bunker scale weighing sensor 2 is for measuring limit
The reaction force that position mechanism generates.Load cell 1 and the split type structure of scale correcting apparatus 4, reduce the self weight of single machine, more square
Just transport and operation.The locking of locked mechanism allows force value source to have mechanical structure to keep, and reaches a stable load.
It is equipped with hydraulic cylinder and elevating lever 41 in the scale correcting apparatus 4,41 upper end of elevating lever is fixed with force-measuring sensing
Device 1, the hydraulic cylinder are connected with driving mechanism 7, and the speed driving mechanism 7 drives hydraulic cylinder to go up and down elevating lever 41.Institute
Stating locked mechanism 6 is lock screw, and lock screw is sheathed on elevating lever 41.Lock screw locking elevating lever 41 makes elevating lever
It can not go up and down.
The position-limit mechanism is portal frame 5, and the portal frame 5 is set up in 1 top of load cell.It builds conveniently, is convenient for
