JPS5928328Y2 - Automatic weighing device for farmers - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a simple automatic weighing device that farmers can purchase and use for their own use.

In conventional grain weighing devices, the cylindrical part of the elevator is fixed to the side of other equipment by complicated fixing means or buried in the floor. The entire device was large because it was installed through a discharge gutter.

Furthermore, because platform scales for grain weighing are either placed on the elevator support or touch the elevator support when set in their use position, the vibrations of the elevator are transmitted to the platform scale, resulting in accurate weighing. It is not possible to perform measurements, and there is also the disadvantage that when setting the platform scale to the use position, vibration is applied to the platform scale, causing it to go out of order.

This is particularly important when the switch on the platform scale is electrically connected to an automatic on-off valve provided at the tank outlet.

This is because platform scales with switches are sensitive and vibration is their natural enemy.

That is, in the weighing device described in Japanese Patent Publication No. 29-2313, a frame for supporting the weighing machine is provided around the discharge opening at the bottom end of the funnel, and the funnel is attached to this frame.

The vibrations of the weighing machine and the funnel, which are composed of a balance frame, a balance beam device mounted thereon, and a display device, are transmitted to the weighing machine,
Accurate weighing with a weighing machine is not possible, and it is troublesome to attach the weighing machine to the frame, and there is no interlocking mechanism between the weighing machine and the funnel. This was done by attaching external diagonal girders, which made the whole structure large and required a large number of parts.

The present invention addresses the above-mentioned problems, and the elevator only needs to have a base plate attached to the lower end of the cylindrical part, does not require any other members such as diagonal girders, and can be made compact with a small number of parts and can be installed in any location. By forming a notch in the bed plate from the side and installing the platform scale inside this notch, the platform scale can be placed at a specified position on the elevator while sliding or rolling on the ground without touching the plywood of the elevator. The switch on the platform scale can be installed without any unnecessary external force acting on the switch of the platform scale, and the platform scale does not come into contact with the elevator after installation, so there is no possibility of inaccurate weighing due to the vibration of the elevator. The object of the present invention is to provide an automatic weighing device for farmers that performs accurate weighing by operating an automatic opening/closing valve.

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 2 denotes a cylindrical portion having a rectangular cylindrical cross section and serving as a pillar of the elevator. A packet belt is wound within the cylindrical portion 2 as is known in the art.

A collar opening 10 for tensioning is formed at a lower position of the cylindrical portion 2.

The height of the cylindrical portion 2 is the height required to feed grain into the container a on the platform scale 5 provided on the side thereof, and is therefore extremely short.

An opening 3 for discharging grains is formed in the upper side of the cylinder part 2.

Normally, a long and short discharge gutter is attached to the upper part of the cylindrical part 2, but in the present invention, the -cut discharge gutter is not installed, and the storage tank 4 is directly attached to the upper side of the cylindrical part 2. is to be installed.

Thus, the base plate 1 is attached to the lower end of the cylindrical part 2 with the storage tank 4 so as to maintain the cylindrical part 2 in an upright state.

Therefore, in the present invention, the cylindrical portion 2 with a storage tank can maintain an upright state without using any fixing means.

The discharge port 11 formed at the lower end of the storage tank 4 is connected to the platform scale 5.
It opens at the top of the upper container a, and an automatic on-off valve 12 is attached thereto.

13 is an electrical actuation device that opens and closes the automatic on-off valve 12;
4 is a switchboard that sends a signal to the electrical actuation device 13; 15 is a scale rod of the platform scale 5; 16 is a switch; and 17 is a cord.

Further, 6 is a notch formed from the side so as not to give vibration to the platform scale 5, 7 is a motor, 8 is a passive wheel, and 9 is a belt.

In the above configuration, when the motor 7 rotates the driven wheel 9 and grains are supplied from the supply port 10, the grains are delivered to the cylindrical portion 2.
The liquid rises inside and is stored in the storage tank 4 through the opening 3.

Next, when the container a is placed on the platform scale 5 and the switch on the switchboard 14 is connected, the electric actuator i3 is energized to open the automatic on-off valve 12 and the discharge port 11 to open the storage tank 14. The grains inside flow into container a.

When the grain discharge reaches a predetermined amount, the weighing rod 15 of the platform scale 5 stops moving, so that the switch 16 is automatically operated and sends a signal to the electric actuating device 13 to automatically close the automatic opening/closing valve 12. let

As described above, in the present invention, an opening 3 is provided on the upper side surface of the cylindrical portion 2 of the elevator, and the storage tank 4 connected to the opening 3 is directly attached to the side surface of the cylindrical portion 2. Not only is it not necessary to form a large discharge gutter, but it can also be formed compactly.
The cylinder part 2 with the storage tank 4 has a base plate 1 attached to the lower end of the cylinder part 2 so that the cylinder part 2 with the storage tank 4 can be maintained in an upright state without using other fixing means such as an external diagonal rod. It has the effect of being able to be installed in any situation, and since the outlet 11 of the storage tank 4 is opened at the top of the container a on the platform scale 5, it becomes a weighing device with a very simple configuration, and can be used by farmers as their own equipment. In addition to having the advantage of being able to implement equipment that can be purchased at a low cost, the platform scale for weighing does not touch the elevator, so the vibration of the elevator will not be transmitted to the switch on the platform scale that is electrically connected to the tank discharge port. The switch action is accurate, and the platform scale slides or rolls on the ground without touching the plywood through the notch provided from the side of the plywood, allowing it to be mounted as close to the cylinder of the elevator as possible, making it easy to hold the platform scale. Since there is no need to raise the scale, the mounting operation is extremely easy, and there is no need to apply unnecessary external force to the platform scale during mounting, and there is no possibility that the switch will go awry.
