Abstract

PURPOSE:To facilitate assembling without requiring no reinforcing member and to enable accurate measurement, by interposing a detection unit, wherein a fixing side and a force acting point side were connected by parallel beams, to the lowermost end of each of the support legs of a silo. CONSTITUTION:Each detection unit 9 is interposed between the lowermost end of each silo support leg 1 and the foundation 2. The fixing side member 10 of the unit is mounted to the foundation 2 by an anchor bolt 11. The force acting member 12 and member 10 welded to the lowermost end of the support leg 1 are connected at two upper and lower places as parallel beams through two leaf springs 13, 14 to constitute a mechanism. A shearing type load cell LC Is attached to the bracket 16 of the member 10 at one end thereof by a bolt 15 and the other end of said load cell LC is engaged with the bracket 18 of the member 12 through a hanging rod 17 to be pulled downwardly. Because the support leg 1 is supported through the unit 9 as mentioned above, lateral load and bending moment are supported by the leaf springs 13, 14 and no reinforcing member is required. Further, a weighing value is obtained from the output by the adder output of the load cell LC.

BACKGROUND OF THE INVENTION Conventionally, this type of scale for feed silos has been constructed as shown in FIG. 10 or 11. Figure 10 shows a load cell of the lower type, with a pressure type load cell /l/ (3) interposed between each silo support leg (1) and the foundation (2). ) The load cell (3) and the silo support leg (1) are in point contact to prevent a bending moment from acting on the silo and reducing accuracy. Furthermore, since the two are in point contact as described above, a sash (4) is provided between the two and the fixed side to counteract lateral loads. Figure 11 shows a top-mounted load cell, with only a compression type load cell/v (3) interposed between the silo support leg (1) and the silo (5). ) is the 10th contact with
As shown in the figure, 1 and sash (4) are required for point contact.

Function: With this configuration, the silo is attached to the stationary side via the detection unit rather than by point contact, so no sash is required. Moreover, since the silo support leg of some length is interposed between the silo and the sliding type load cell that detects the load at the force application point of the detection unit, accuracy and linearity are improved.

First, consider a case where the detection unit (9) is interposed between the silo (5) and the upper end of the silo support leg (1). In principle, the detection unit (9) incorporating the shear type load cell/I/(LC) detects only the shear force even if a bending moment or lateral load is applied, so it detects only the load acting in the vertical direction. Can be measured. However, since it is difficult to completely detect only the shear force in the dark, accuracy decreases when a large bending moment or lateral load is applied. The silo (5) can be considered as an equivalent tAg3 with an equivalent elastic modulus and an equivalent moment of inertia as shown in FIG.

On the other hand, when the detection unit (9) is interposed in the middle part or the lowest end as in the present invention, it can be expressed as shown in FIG. The rigidity of the tabs and silo support legs (1) is
If the steel column is smaller than the steel column in 5), the silo support leg (1

The bending moment 1-M2 at is smaller than that in Fig. 6 (

To this extent, the longer the length of the silo support leg (1) interposed between the silo (equivalent beam) and the load set/L/(LC), the smaller the bending moment, and the smaller the bending moment, the load set/L/L. /(LC) straight line 1□ property is improved and four corner errors become easier.

As described in the detailed description of the invention, the feed silo scale ρ of the present invention has a detection unit in which the fixed side and the force-applying point side are connected by a parallel beam, installed in the middle part or the lowest end of the silo supporting legs, and detecting the applied force. Since the load acting on the point side is measured with a shear type load cell, there is no need for metal fittings such as sashes that were required when using a compression type or cantilever beam type load cell in the conventional point contact state. The new structure actively utilizes the elasticity of the interposed silo support legs by interposing the detection unit in the middle or the bottom end of the silo support legs, so there is no possibility of deterioration of the linearity of the load set μ due to bending moments. It is possible to prevent this and achieve highly accurate measurement. In addition, it is easy to roll the silo support leg by interposing the detection unit in the middle or the lowest end, and to assemble it into an existing feed silo.
