Description

[Detailed description of the invention] Industrial applications The present invention provides a closure for measuring rice bins.

Structure of conventional measuring rice jugs and their problems In conventional weighing rice jugs, when measuring a certain amount of rice, it is common to place a rice container under the rice discharge port and perform the weighing operation. Many measuring rice jugs allow you to perform measuring operations with or without a rice container. Therefore, if you forget to insert the rice container and perform the weighing operation, a large amount of rice will spill onto the floor where the rice bin is installed or the bottom of the rice bin.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks by providing a dedicated rice receiving container and a structure in which rice does not come out even if the measuring operation is performed when there is no rice receiving container. purpose.

Structure of the Invention In order to achieve the above object, the present invention provides an opening/closing lid for locking the discharge of rice at the lower end of the rice metering/discharging opening, and inserts an operating pestle connected to the opening/closing lid into the insertion space of the rice receiving container. The opening/closing lid is made to protrude, and when the rice receiving container is inserted, the operating pestle is pushed by the rear wall to open the opening/closing lid, and when the rice receiving container is taken out, one end of the opened opening/closing lid is pulled to close it again. By simply inserting and taking out the removable rice container, the discharge port can be closed when there is no rice container, allowing the rice to spill onto the floor or bottom, and once the rice container is inserted, normal operations can be performed. The rice can be discharged using the lid, and no special operations are required to open and close the lid, making it safe to use.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, a measuring rice jug 1 is equipped with a measuring operation lever 2 on the front, and a dedicated rice receiving container 3 below it.
, which can be attached and detached from the front.

In FIG. 2, reference numeral 4 denotes a measuring chamber, in which rice flowing from the rice storage section above is measured by a measuring device 5 and discharged into the rice receiving container 3 through a discharge port 6. The measuring instrument 5 can swing around a shaft 7, and has an upper shutter 8 and a lower shutter 9 on the upper and lower sides, respectively. When a measuring operation is not performed, the lower shutter 9 closes the discharge inside the measuring chamber 4 by the force of a spring or the like. It is inserted near the outlet 6 to prevent the rice from falling. When the weighing operating lever 2 on the front is pushed down, the measuring instrument 5 swings about the shaft 7 by the cam 10 provided at one end of the operating lever 2, and the upper shutter 8 is inserted into the measuring chamber 4, and at the same time, the lower shutter is inserted into the measuring chamber 4. 9 is measuring room 4
It comes out more. The upper shutter 8 stops the rice from falling from the rice storage section, and the lower shutter 9 can be opened to discharge a certain amount of rice from the upper and lower shutters 8 and 9.

The discharge port 6 is provided with an opening/closing lid 11 that closes the discharge port 6, and when the opening/closing lid 11 closes the discharge port 6, rice will not fall below the discharge port 6 even if a metering operation is performed. There isn't.

The opening/closing lid 11 is connected to a shaft 1 provided at the lower end of the discharge port 6.
It can be opened and closed using 2 as a fulcrum, and has an operating punch 13 at one end. The operating pestle 13 is the opening/closing lid 1
When the rice container 1 is blocking the discharge port 6, it protrudes downward into the space where the rice container 3 is taken in and out, and when the rice container 3 is inserted in this state, it hits the rear end 3' of the rice container. come into contact with

One end of a tension spring 14 is attached to the side of the operating punch 13, and the other end is fixed to a part of the outside of the measuring chamber 4. When the opening/closing lid 11 is closing the discharge port 6, the force of the tension spring 14 is applied in the direction of closing the opening/closing lid 11.

When the rice container 3 is inserted, the operating pestle 13 is pushed by the rear end 3', and the tensile force of the tension spring 14 connects the fixed end of the tension spring and the pivot point 12 of the opening/closing lid 11 on a straight line. Beyond a certain bottom dead center, it begins to act in the direction of opening the opening/closing lid 11. Opening/closing lid 1
1 is opened, and the operating pestle provided at its tip or on the opposite side from the operating pestle 13 is inserted into the rice receiving container 3, as shown in FIG. When the rice container 3 is removed, the opening/closing lid 11 is pushed in the closing direction by the rear end 3', and the tension spring 14 passes the bottom dead center again.
A tensile force is applied in the direction of closing the opening/closing lid 11.

As described above, according to this embodiment, the rice receiving container 3
When the rice receiving container 3 is not inserted, no rice will be discharged even if a metering operation is performed by mistake because the discharge port 6 is blocked by the opening/closing lid 11, and when the rice receiving container 3 is inserted, Operation pestle 13 at one end of the opening/closing lid 11
is pushed at the rear end of the rice receiving container 3 to open the opening/closing lid 11 and enable the rice to be discharged. In addition, the tension spring 14, which had been acting in the direction of closing the lid 11, now acts in the direction of opening the lid 11, so that if the tip of the lid 11 comes off the rear end 3' of the rice container, If the discharge port 6' is immediately closed, or if the tip of the opening/closing lid 11 remains on the rear end 3' of the rice container, applying force to push the rice container 3 forward. There's nothing wrong with that. When the rice receiving container 3 is pulled out, the tip of the opening/closing lid 11 is inserted into the rice receiving container 3, so the opening/closing lid 11 is opened by the rear end 3'.
is rotated in a direction to close the tension spring 14.
The opening/closing lid 11 is closed by force, and the loading/unloading of the rice receiving container 3 and the opening/closing of the rice discharge port 6 are linked, so that even if the rice receiving container 3 is operated incorrectly, the rice will not be spilled if there is no rice receiving container. can be prevented.

Effects of the Invention As described above, the present invention has the following effects.

1. If the rice receiving container is not inserted, rice will not be discharged even if the metering operation is performed by mistake, so rice will not be scattered on the bottom or floor.

2. When the rice receiving container is inserted, the rice discharge port will automatically open and measurement operations can be performed at any time. This is extremely convenient because no extra operations are required.

3. Also, the discharge port is automatically closed when the rice container is removed, so even if the measuring device or the like breaks down, the discharge port will be double blocked, allowing for worry-free use.
