Abstract

(57) [Abstract] [Purpose] To provide a measuring device for powder and granular material, in which the measuring capacity can be easily changed and the rising is suppressed. [Structure] A part of the wall surface of the rotary weighing box is formed slidably in the axial direction. By fixing this wall surface at a predetermined position, a desired measuring capacity is set. A weighing box is placed under the hopper, and the granules are charged. After the powder of a predetermined volume is put into the weighing box, the weighing box is rotated by a predetermined angle, and the powder of the predetermined volume is discharged downward or sideways. By changing the rotation angle or the rotation direction, the powder or granular material is discharged to one place or a plurality of places. The granular material is stored as it is in a plastic bag attached to each outlet.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a powder and granular material measuring device, and in particular, a variety of small-lot production of soil conditioners (peat moss, vermiculite, perlite, etc.), seeds, horticultural soil (akadama soil, Kanuma soil, pumice stone, etc.) The present invention relates to a device that can easily measure powder particles of a predetermined volume.

[0002]

[Prior art]

 Conventionally, when measuring a predetermined amount for packaging a powder or granular material, the weight of the product is usually measured. This is because, when mass-producing small varieties in a factory, it is more efficient to weigh and package the products.

However, some products are packaged by measuring in volume. Many soil-improving agents (peemos, vermiculite, perlite, etc.), seeds, horticultural soil (Akadama soil, Kanuma soil, pumice stone, etc.) are measured in volume and subdivided into plastic bags. .

In the case of measuring such a small amount of a wide variety of products, an operator manually puts the products into an appropriate measuring container to measure a desired amount of the product. If the amount is small, the product is weighed, and if the amount is large, the product is put into a measuring container such as a bucket with a scoop and weighs a fixed amount.

[0005]

[Problems to be solved by the device]

 According to the conventional weighing method, when transferring products, a part of the powdery product floats up in the air and the working environment deteriorates. Therefore, it is necessary to work with a dust mask.

Further, the operator puts the product in a dedicated measuring container manufactured for each packaging unit of the product, measures the product, and packs the product in a bag. All of these were manual work, and the work efficiency was extremely poor.

[0007]

[Means for Solving the Problems]

 The present invention provides a measuring device for powder particles which solves such a problem. The powdery-measuring device of the present invention comprises a powdery-grain storage container having a powdery-grain supply port below, and a powdery-grained body located below the container for receiving a predetermined volume of powder and discharging the powdery or laterally. And a measuring volume adjusting mechanism that adjusts the measuring volume by moving and adjusting the wall surface of the measuring box.

[0008] Further, a driving unit that rotates the measuring unit and discharges the powder and granules to the measuring unit, and a measurement volume adjustment that moves the wall surface of the measuring unit in the rotation axis direction to adjust the measurement volume. And a mechanism.

Further, the driving unit is characterized in that the measuring box unit is rotated by a predetermined angle to discharge the powder or granular material at a plurality of positions.

Further, the driving unit is characterized in that the metering box unit is rotated in the forward and reverse directions to discharge the powder and granular material at a plurality of locations.

[0011]

[Action]

 The measurement volume can be easily changed by moving and adjusting the wall surface of the weighing box. Also, by attaching a packaging bag such as a vinyl bag to the outlet, the powder of the product does not rise and the working environment can be improved. By rotating the measuring section by a predetermined angle, the powder and granules can be sequentially discharged from the plurality of discharge ports, and the work efficiency is good. By rotating the weighing box in the opposite directions, powder and granules can be discharged on both sides of the weighing device, further improving work efficiency.

EXAMPLES Hereinafter, an example of a powdery or granular material measuring device according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a main part of a powdery or granular material measuring device according to the present invention. A rotary box 2 is arranged under the hopper 1, and a powder / particle discharge port 3 is further provided under the rotary box 2. The rotating box part 3 includes a fixed box 4 fixed to a powder and granular material supply port (not shown) at the bottom of the hopper 1, a rotating box 5 rotatably fitted to the fixed box 4, and a side of the fixed box. It is composed of a rotating box holder 6 which is fixed to one side and supports a rotating box 5.

2 and 3 are perspective views of the rotary box 5 according to the present invention. The rotary box 5 is fitted to the rotary shaft 7, fixed wall members 9 and 9 ′ that form the inner wall surfaces 8 and 8 ′ of the box, and the rotary shaft 7 in a slidable manner, and a part of the inner wall surface of the box. And a sliding wall member 11 forming a sliding wall surface 10. The sliding wall member 11 has a through hole 12 formed therein for fitting with the rotating shaft 7, and is fitted as shown in FIG. When the sliding wall member 11 is slid along the rotary shaft 7 and fixed at an appropriate position, the volume of measurement of the granular material is defined. That is, the inner wall surface of the fixed box 4, the fixed wall surfaces 8 and 8 ′ of the rotating box 7, and the sliding wall surface 10 form a weighing box space 13.

FIG. 4 is a cross-sectional view taken along the line A-A ′ of the rotary box in FIG. The space surrounded by the shaded portion and the alternate long and short dash line is the measurement space 13, 13 '. Since there are two weighing spaces, it is possible to discharge the granular material downward from the opposite measuring space while supplying the granular material to one. One measuring space may be provided, but it is more efficient to provide two or more measuring spaces.

FIG. 5 is a sectional view of a weighing box according to another embodiment. The granules are fed by their own weight from the hopper or discharged from the weighing box. Various shapes of the weighing box can be considered depending on the bulk specific gravity, surface shape, water content, stickiness, etc. of the granular material, but the present invention is not limited to the shape of the weighing box of the embodiment.

When changing the measurement volume, the sliding wall member 11 is slid along the rotary shaft 7 and fixed to the rotary shaft 7 by the stopper 14.

FIG. 7 is a cross-sectional view of a main part of a weighing device capable of discharging the weighed powder and granules at two positions, as viewed from the rotation axis direction. Since the outlets 3 and 3'are provided on both sides of the weighing device, the bags can be alternately packed and the working efficiency is very good. FIG. 6 is a sectional view of a weighing box of this weighing device. There are three weighing spaces 13, 13 ', 13 ", which rotate in the forward and reverse directions by 120 degrees each. A foot switch (not shown) and an operator are arranged on both of the weighing devices, and the operator operates the foot switch. When stepped on, the weighing box 5 rotates to the front side, and the granular material is discharged from the outlet in front of the eyes.When working alone, rotate the weighing box 5 in only one direction.

【effect】

 The powder and granular material measuring device of the present invention can easily change the measuring volume, the powder of the product does not rise, and a good working environment can be maintained. Further, the powder and granules can be discharged in order from a plurality of discharge ports, and the powder and granules can be discharged on both sides of the weighing device, so that the working efficiency is greatly improved.
