Abstract

PURPOSE:To make easily a silo into a measuring instrument by cutting and removing one lower part of the supporting leg of the silo so as to assemble a load detecting unit and assembling sequentially the detecting units on other supporting legs. CONSTITUTION:A lower frame 20 is assembled on a base 2 so that the supporting leg 1a of the silo 5 supported by silo supporting legs 1a-1d can be enclosed, connected on the base 2 with an anchor volt 11 and welded and fixed on the supporting leg 1a. Afterward, the lower end of the supporting leg 1a is cut into the prescribed length so as to remove and the fixed side member 10 of the detecting unit 9 and an attachment point side member 12 are assembled between the lower frame 20 and the lower end of the supporting leg 1a. The detecting units 9 are assembled on the remaining supporting legs 1b-1d in the same manner. Thus it is unnecessary that the silo 5 is completely hoisted by a crane and is landed on the ground, and accordingly the silo 5 can be made into a measuring instrument with a simple construction.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a method of constructing a scale for a feed silo.

BACKGROUND OF THE INVENTION Conventionally, this type of scale for feed silos has been constructed as shown in FIG. 7 or 8. Figure 7 shows a load cell type that is placed below, with a compression type load cell (3) interposed between each silo support leg (1) and foundation (2), and a bending moment acts on the load cell (3). The load cell (3) and the silo support leg (1) are in point contact so as not to reduce accuracy. In addition, since the two are in point contact, there is a sash (four sashes) between the fixed side and the fixed side to counteract lateral loads.
) is provided. Figure 8 shows a top-mounted load cell.
Only the compression type load cell (3) is interposed between the silo support leg (1) and the silo (5), and the load cell (
The contact between 3) and the silo (5) is point contact as in Fig. 7, and a sash (4) is required.

In the case of a top-mounted type as shown in Fig. 8, some load cells (3) are not compression type but are shown in Fig. 9 or 10.
As shown in the figure, there is a type that uses a cantilever beam type load cell (6), but in either case, it is in point contact with the silo (5) or is only suspended, so the sash (4) should be eliminated. It is not possible. Note that (7) is a steel ball and (8) is a hanging rod.

Conventionally, when assembling a weighing section to an existing feed silo, the silo (5) was immediately lifted from the support legs (1) with a crane, etc., or the silo (5) was once lowered to the ground. A construction method is adopted in which the silo (5) is assembled and installed with a load cell (4), and finally the silo (5) is placed in its original state.

Problems to be Solved by the Invention In such a conventional construction method, it is necessary to completely lift the silo (5) or lower it to the ground, which requires extensive work. Furthermore, in the case of a silo or the like installed in a building, there is a problem in that it is difficult to bring a crane or the like into the building, making it impossible to assemble the weighing device.

An object of the present invention is to provide a method for constructing a scale for a feed silo, which allows a weighing device to be easily assembled into an existing feed silo.

Means for Solving the Problems The method for constructing a scale for a feed silo of the present invention is such that one end or middle part of a silo supported by a plurality of support legs is extended over the size of a load detection unit. The load detection unit is assembled to the removed cut portion, and after this assembly is completed, one of the supporting legs that remains is cut and removed in the same way and the load detection unit is assembled in the same way, thereby attaching multiple units to the silo. It is characterized by being equipped with a detection unit.

Function: With this configuration, the weighing section with a new configuration that does not require the conventional sash (4) is sequentially attached to the support legs, making it easy to lower the silo (5) to the ground or completely lift it up. It can be used as a scale for feed silos without any addition, and construction is easier than before.

EXAMPLES Hereinafter, the construction method of the present invention will be explained based on specific examples.

1 to 4 show an embodiment of the present invention, and FIG. 1 shows a front view of a completed feed silo scale. (5) is the silo, (1m) to (1d) are the silo support legs, and (9) is the lowest end of each silo support leg (1a) to (1d) and the foundation (2
) is a load detection unit interposed between the

The load detection unit (9) is constructed as shown in FIG. αQ is a fixed side member, which is attached to the foundation (2) with anchor bolt 0◇. (6) is the silo support leg (
The force-applying side member is welded to the lowermost end of 1a) to (1d), and the force-applying side member @ and the fixed side member αQ are connected at two places, upper and lower, via a two-plate spring a304 as a parallel beam. This constitutes a robal pal mechanism. (LC) is a sliding type load cell, one end is attached to the bracket (III) of the fixed side member αQ with a bolt α0, and the other end is attached to the bracket (III) of the force side member (6) via a hanging rod αη.
) and is pulled downward. (to) is the side cover.

In this way, each of the silo support legs (1a) to (1d) was supported via the load detection unit (9), so the lateral load and bending moment were absorbed by the leaf spring (
It is supported by Lm Q41 and does not require a traditional sash (4). Note that the weight value is obtained from the summation output of the load cell (LC) in each detection unit (9).

As described above, the load detection unit (9) is attached to each of the silo support legs (1a) to (1d) through the following steps. FIG. 4 shows the process of first assembling the load detection unit (9) to (1a) of the silo support legs (1a) to (ld). First, the silo support leg (1a) of the silo (5) supported by the silo support legs (1 set) to (1d)
Place the lower frame (1) on the foundation (2) to surround the
Assemble it as shown and attach it to the anchor bolt αυ.
(2), then attach the lower frame (rolling) to the silo support legs (1a
), and as shown in Figure 4(e), attach the silo support legs (
The lower end of 1a) is cut off over a predetermined length at the position of the lower frame (roll).

Next, as shown in Figure 4(d), the lower frame members and silo support legs (
After assembling each part so that the structure shown in FIG. 8 is obtained between the lower end of the silo support leg (Lm), the force application side member (2) and the silo support leg (1a) are welded.

When the assembly to the silo support leg (1a) is completed in this way, one of the remaining silo support legs (lb)-6 (ld), for example, the silo support leg (1b), is attached in the same manner as shown in FIG. The load detection unit (9) is assembled to one silo support leg, then the silo support leg (1c), then the silo support leg (1d), and so on.

In this way, the next silo support leg is removed after assembly is completed, so the silo (5) is supported by the remaining eight silo support legs, and the silo (5) does not tilt significantly.
The weighing device can be assembled to the feed silo without completely lifting it from the silo support legs (1st leg) to (IC) or lowering it to the ground.

In the above embodiment, the load detection unit (9) is a plate spring (to).

A beam (strain body) that has parallel beams that make up the donkey pal mechanism that rotates the body, and has a strain gauge attached between the parallel beams to detect shear stress.
One end of the load cell body is attached to the fixed side member αQ with a bolt (2), and the force-applying point side member (6) is secured with a bolt to the other end, so that the plate spring (2) α ◆ can be omitted.

In the above embodiment, the detection unit (9) is connected to the silo support leg (1).

A similar effect can be obtained by interposing it in each intermediate portion of (1d).

In the above embodiment, the number of silo supporting legs is four, but the same applies if there are eight or more than four silo supporting legs.

As described in the detailed description of the invention, the feed silo scale construction method of the present invention includes cutting and removing the lower end or middle part of one of the support legs of a silo supported by a plurality of support legs over the size of the load detection unit. Then, a load detection unit is assembled to this removed cut section, and after this assembly is completed, one of the remaining support legs is cut and removed in the same way and the load detection unit is assembled in the same way, thereby installing multiple detection units in the silo. In order to install the feed silo, it is possible to turn a feed silo into a weighing device with simple construction without having to use a crane or the like to completely lift the silo upwards or lower it to the ground.
