Fig. 2 is a left view of the present invention.
Fig. 3 is the cut-open view of the A-A of Fig. 1.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 1～shown in Figure 3: comprise compositions such as scale bucket 1 (side plate 11, clamping plate 12, bending plate 13), rubber damping piece 2, web joint 3 (upper overturning 31, flange 32) down, U type damping block 4, elastic body 5, LOAD CELLS 6, electromagnet 7, feeder trough 8 and bending plate 9.
The present invention adopts the vertical scale bucket 1 of installing on side plate 11 1 sidewalls is being installed, on installation side plate 11 back side sidewalls that scale bucket 1 is installed, be provided with LOAD CELLS 6, LOAD CELLS 6 is installed on the bottom surface of stretching out the limit of bending plate 9, and the installation limit of bending plate 9 is connected installs side plate 11 walls.Bending plate 9 bending angles are the right angle.
The bottom of scale bucket 1 is provided with discharging opening, and this discharging opening stretches in the feeder trough 8 that scale bucket 1 below is provided with, and is provided with at scale bucket 1 sidewall clamping plate 12 are installed, and is provided with electromagnet 7 at corresponding feeder trough 8 tail positions of installation side plate 11 bottom sidewalls of scale bucket 1 one sides.On installation clamping plate 12, be provided with the vibration absorber that surrounds scale bucket 1 sidewall.
Described vibration absorber is made of rubber damping piece 2, web joint 3, U type damping block 4, elastic body 5 (latch plate), rubber damping piece 2 is installed on web joint 3, web joint 3 bottoms are connected with U-shaped damping block 4, and U type damping block 4 is connected with elastic body 5 (latch plate).Elastic body 5 (latch plate) lower end links to each other with web member on the feeder trough 8.Electromagnet 7 links to each other with installation side plate 11 on the scale bucket 1, and each parts connects with securing member, forms micro-feed weighing structure.Play the effect of vibration damping when making vibration wave successively, prevent the vibration effect LOAD CELLS 6 of electromagnet 7 and feeder trough 8 by vibration isolation rubber piece 2, U type damping block 4.
The upper overturning 31 that is provided with on the web joint 3 is being taken in rubber damping piece 2 upper surfaces, and the bottom of web joint 3 is provided with the following flange 32 that stretches out to scale bucket 1, surrounds the U type damping block 4 of scale bucket 1 sidewall on the following flange 32.
It is the quadrangular shape that described scale bucket 1 is epimere; The stage casing is inverted truncated rectangular pyramids shape; End section is quadrangular shape or the funnel that joins successively.Being provided with bending angle on the lateral wall of the stage casing of scale bucket 1 is the bending plate 13 of acute angle, and the limit level of stretching out of bending plate 13 is stretched out, and the installation limit of bending plate 13 is connected on the stage casing lateral wall of scale bucket 1.
