Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vertical grain sorting and weighing device that removes fine grains from grains and weighs the grains.

[Conventional technology]

A conventional vertical sorting and weighing device will be explained with reference to FIG. The vertical sorter 45 is passed through a grain lifting machine 46 to a weighing grading tank 47.
．． Shutter device 48. Weighing machine 49 and weighing device 50
A vertical sorting and weighing device 51 is formed. Supply port 5
The grains flowing down from the helix 53 are urged toward the porous wall sorting tube 54 by the centrifugal force caused by the spiral body 53. Porous wall sorting tube 5
The fine grains are removed from the through hole 4 and discharged outside the machine from the fine grain discharge port 55, and the sized grains that are not removed are sent from the grain size discharge port 56 via the grain lifting machine 46 to the grain size grading tank 47 for weighing. . When a certain amount of grain accumulates in the weighing grading tank 47, the shutter device 48 is opened and the grains are supplied to the bag body 57. When the weighing machine 49 detects the set weight, an electric signal from the weighing machine causes the shutter to close. @48 is closed and weighing is completed.

However, in the conventional vertical sorting device as mentioned above,
As shown in Fig. 4, the vertical sorter 45 and the weighing grading tank 47 are arranged on the left and right sides of the QR 46, so the installation area is large, making it difficult to work in a narrow workshop such as a farmer's barn. The problem was that it was difficult.

[Problem that the invention seeks to solve]

It is an object of the present invention to solve the above-mentioned problems and to provide a vertical grain sorting and weighing device that has a significantly reduced installation area.

[Means for solving problems]

In order to achieve this object, the present invention has the following configuration.

A perforated wall sorting cylinder is rotatably installed inside the vertical machine cylinder, and a rotating body with a spiral body suspended around the circumference is fitted inside the porous wall sorting cylinder to form a vertical sorting machine.

The grain sizing discharge port installed at the bottom of the porous wall sorting tube and the grain sizing tank for weighing installed at the top of the vertical sorter are connected by a grain lifting machine to form a vertical sorting and weighing device. It is equipped with a discharge shutter electrically connected to the weighing machine. A locking fitting is provided to detachably connect the weighing grain size tank and the grain lifting machine.

[For production]

The grains supplied to the feed port of the vertical sorter are subjected to centrifugal force due to the rotation of the spiral body, and fine grains are removed from the perforated wall sorter tube, and the unremoved grains are sent to the grain lifter for weighing. Sent to a grading tank.

Then, when the weighing machine senses the set weight of the grains supplied from the grading tank to the bag body, the discharge shutter is closed and the weighing is completed. In addition, when replacing the porous wall sorting tube, first the locking metal fittings are released, and then the weighing sizing tank is removed from the grain lifting machine. Then, the porous wall sorting tube is pulled out from the vertical sorter and replaced.
