Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a simple weighing scale, that is, a simple weighing device for livestock that is used by farmers who raise livestock to manage the livestock while checking the growth process. It is something.

[Conventional technology]

Conventionally, there are scales for measuring the weight of livestock produced by specialized scale manufacturers, but these are regular scales for commercial use, and most of them are computerized and have specifications that allow each animal to be managed by coding. be.

[Problem that the invention attempts to solve]

The conventional measuring instrument is a commercial measuring instrument,
Because of the above configuration, it is very expensive and has a problem in that the number of buyers is limited, and farmers who raise livestock prefer to use high-precision products for commercial purposes.
Rather, it would be very convenient for livestock management if the weight could be easily measured as a guide to the growth process of livestock and it was inexpensive, but at present it is accurate with little measurement error and easy to handle. Therefore, there was no economically inexpensive weighing device for livestock.

In view of these points, this invention is not intended for commercial use, and does not consider management by computer.
The purpose of the present invention is to provide a simple, assembled scale for livestock that is easy to handle and transport, has a simple configuration, and is inexpensive.

[Means for solving problems]

The structure of the present invention to achieve the above purpose is as follows:
To explain using FIGS. 1 to 3 corresponding to the embodiment, a weighing table 1, a bottom plate 2 for weighing, and a digital display section installed on the bottom plate 2 between them are attached to the bottom plate independently of the main body. A process consisting of a digital health meter 3 placed outside, and using a combination of arbitrary levers to measure the weight on the weighing platform 1, the side edges of which are supported at the four corners of the bottom plate 2 for weighing. It is reduced by the lever ratio of the force point part 6a that supports the weighing platform 1 at a position inside the support part 8a of the connecting arm 5, and the point of action 7 of the connecting arm 5 placed on the health meter 3 in the center with respect to the fulcrum. At least tell health meter 3, and health meter 3
This is a simple prefabricated livestock weighing device configured to convert and restore the reduced numerical value into a multiplied leverage ratio and display it on a digital display 4 placed outside the bottom plate.

[Effect]

The present invention has the above-mentioned configuration, and the health meter 3 is installed on the bottom plate 2, and the four corners of the health meter 3 are supported using the four side ends of the connecting arm 5, which is connected at the center, as a fulcrum. The center point of action 7 is placed on the health meter 3, and the assembly is such that the weight on the weighing platform 1 is applied to the support pin 6 of the connecting arm 5, so the weight on the weighing platform 1 is applied to the connecting arm 5. It is transmitted to the health meter 3 by reducing the leverage of the force point 6a and the point of action 7. Suppose the leverage is 1/
If it is 10, the mechanism transmits 1/10 of the weight on the weighing platform 1 to the health meter 3, and the weight transmitted to the health meter 3 is calculated by the reduction ratio inside the digital display 4 placed outside the bottom plate. Restored to twice its normal weight as shown. By doing this, it is possible to measure weights up to twice the lever ratio of the measurable range of Health Meter 3, and by improving the health meter so that only the digital display part is placed outside the bottom plate, it is possible to easily measure up to 1 ton. Measurable.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 indicates a weighing platform of the present device, and 2 indicates a bottom plate for weighing, both of which are composed of rectangular plates approximately 900 to 1000 mm in length and approximately 1500 mm in width.

3 is a digital health meter whose display part is installed on the bottom plate 2 and is independent from the main body, and is connected to a digital display appropriately installed outside the bottom plate 2 by a cord 4a.

The connecting arm 5 is configured with an arbitrary lever ratio, and the four arms 5 assembled in the mold
a, 5b, 5c, 5d in the middle and bolt 10
One side end of the lever is supported by a blade receiver 8 which serves as a fulcrum attached to the four corners of the bottom plate 2, and the protruding point of action 7 of the pestle 5e provided in the middle is connected to the health meter. It is designed to be placed on top of 3.

Supports 11 having fitting grooves are provided on all sides of the back surface of the weighing platform 1, and each of the four supports 11 is connected between the fulcrum 8a at the side end of the connecting arm 5 and the point of action 7. Arms 5a, 5b, 5c, 5d
The weighing platform 1 is supported by being mounted on support pins 6 provided at The health meter 3 is configured to transmit the reduced value by the amount of leverage, and in the digital display 4, the reduced value is converted to the leverage multiplied, restored, and displayed as a real value. In the figure, 12 is a start/reset switch;
13 is a power switch that turns the power on and off;
Reference numeral 14 denotes a plug, which can be plugged into an outlet or powered by batteries. The weight of the weighing platform 1 is applied to the health meter 3 by the leverage of the connecting arm 5, and a value is displayed on the display section of the digital display 4 as a tare.
When the start/reset switch 12 is pressed when measuring the weight of livestock, a zero display is displayed, allowing the actual weight to be measured.

In addition, by changing the position of each support pin 6 of the connecting arm 5, the length ratio between the point of action 7 and the point of force 6a relative to the fulcrum 8a can be set to 10:1 or 5:1, and the lever ratio can be freely changed. With this, a small health meter designed for weighing 100 kilograms can accurately measure weights up to 1 ton.

The weighing device of the present invention has an accurate measurement error of less than 1%, and is convenient because it allows farmers to easily measure the weight of livestock kept and managed, and to easily understand their growth.

[Effect of idea]

As described above, the present invention consists of a bottom plate, a weighing stand, a connecting arm, and a digital health meter.
This connecting arm reduces the weight on the weighing platform by the amount of leverage and transmits it to the health meter, and since the weight transmitted to the health meter is lighter than the actual weight by the amount of leverage, it is connected to the health meter independently with a cord. By restoring the normal weight and displaying it on a digital display installed outside the weighing platform, it is possible to measure weights up to twice the lever ratio of the measurable range of a single digital health meter, making it easier for farmers to As a weight scale for livestock, it is possible to obtain an inexpensive scale that can measure up to 1 ton with a lightweight health meter, and because it is an assembly type, it is easy to handle and transport, and can be easily used even in remote areas. It is possible. In addition, the lever ratio can be changed as desired, and the actual weight can be digitally displayed and restored easily.
