Description

[Detailed explanation of the invention] (Industrial application field) This invention takes out a part of the grain as a sample before drying it in a drying facility, and measures the granulation yield, moisture content, etc. of the taken out grain. This relates to a sample dryer for investigation.

(Prior Art) In joint grain drying facilities called rice centers, today a method is used to increase efficiency by pooling the grains of each farmer and drying them all at once. In this case, if you do not dry the sample, hull it, or in the case of wheat, put it through a grader to check the yield of grading, etc., you will not be able to accurately determine the ownership ratio when returning the grain after drying to each farmer. This causes the inconvenience of not being able to return the item. That is,
This is because it is not possible to accurately determine each farmer's ownership percentage based on grain weight and moisture content alone.

Therefore, a sample dryer becomes necessary, but if there are many farmers who receive shipments in a day, the moisture differences in the samples from each farmer will vary, so a sample dryer equipped with many drying boxes to dry the samples is necessary. In this case, it is difficult to control the timing of drying of each individual sample, and moreover, frequent moisture determination is required, which makes the process even more complicated. Therefore, as a conventional sample dryer, as shown in Japanese Unexamined Patent Publication No. 56-124883, there has been proposed a sample dryer in which a casing body is provided with a drawer frame having a drying box which can be freely pulled out.

(Purpose of the invention) However, the drawer frame of the conventional sample dryer is
Since the drawer can be drawn out simply by making surface contact with the flange provided on the inner wall of the casing body, the coefficient of friction is high and there are problems such as the drawer frame becoming difficult to pull out when filled with samples.

The present invention provides a sample dryer in which a drawer frame is provided so that it can be pulled out smoothly, and when the drawer frame is stored, the periphery of the drawer frame is sealed to allow ventilation only from the drying box. This is the purpose.

(Structure of the invention) In order to achieve the above object, the present invention provides a casing body 1, an outlet 1b provided in the side wall of the casing body 1, and a
A pair of flanges 5 attached to the inner wall surfaces of the left and right casing bodies, a plurality of pulleys 4 arranged along the inner edges of the flanges 5, and a pulley 4 that can be freely drawn out to the outlet 1b of the casing body 1. A drawer frame 3 which is inserted, has a plurality of drying boxes 2, has notched recesses 3d' at the lower part of both side edges, and has a fixed rail 3d for abutting on the pulley 4.
When the drawer frame 3 is stored in the casing body 1 along the rail, the drawer frame 3
The pulley 4 of the casing body 1 engages with the notch recess 3d' provided in the rail 3d of the sample dryer, and in this state, both side edges of the drawer frame 3 are in contact with the flange 5. be.

(Function) Since the present invention has the above configuration,
When the drawer frame is stored in the casing body, both edges of the drawer frame are pressed against the flanges of the casing body by the drawer frame's own weight, so the airtightness around the drawer frame is high, and the inside of the drying box is Since it can be used as a ventilation path, drying efficiency is improved. Also,
When the drawer frame is pulled out from the storage position, the rail rides on the pulley, so the drawer frame can be pulled out very smoothly.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

First, explanation will be given based on FIGS. 1 to 3.

The front wall 1a of the casing body 1 has an outlet 1.
b is formed, and a drawer frame 3 housing a plurality of drying boxes 2 is inserted into this drawer opening 1b.

The drawer frame 3 is composed of a drawer front plate 3a and a drawer plate 3c having a plurality of drying box insertion holes 3b, 3b, . . . (see FIGS. 4, 5, and 7). The drying box 2 is inserted into each drying box insertion hole 3b, but since the drying box 2 has a flange 2b and a packing 2c is stretched on the lower surface of the flange, the drying box 2 is inserted into the flange. 2b is placed in a crimped state around the insertion hole 3b of the drawer plate 3c. The bottom 2a of the drying box 2 is formed of a perforated plate made of wire mesh, punched metal, etc., and allows hot air to pass therethrough for drying the sample. The drawer frame 3 is designed to facilitate the drawer operation.
Rails 3d, 3d are provided on the lower surface of both side edges thereof, and presser rollers 3e, 3e are provided to slide on a plurality of pulleys 4, 4... provided on the casing body 1, and are rotatably provided on the drawer frame 3. ... comes into contact with the lower surface of the flanges 5, 5 provided on the casing body 1. Also, a part of the lower surface of the rails 3d, 3d is cut out to form a recess 3d' (FIG. 7).

When the drawer frame 3 is pushed into the casing body 1, the recess 3d' is placed above the pulley 4, so in that state, the drawer frame 3 is lowered by the depth of the recess 3d'. , crimped onto the backing 5 on the flange 5.

Further, a packing 3f is attached to the back surface of the drawer front plate 3a of the drawer frame 3 to improve airtightness with the front wall 1a of the casing body 1.

The interior of the casing body 1 is vertically divided into an air supply chamber 6 and an exhaust chamber 7 by the above-mentioned drawer frame 3. The air supply chamber 6 sends hot air to the bottom of the drying box 2 hanging from the drawer frame 3.

In this embodiment, the air that has passed through the electric heater 8 is heated and sent to the air supply chamber 6.

When the drawer frame 3 is pushed into the heater 8
Make sure it is turned on.

A duct 7a is connected to the exhaust chamber 7,
A suction blower 9 is housed in this duct. By driving the blower 9 in conjunction with turning on the heater 8, it is possible to create a flow of hot air from the supply air chamber 6 through the drying box 6 to the exhaust chamber 7.

In the figure, 10 is a switch box containing an electric operation panel, a thermometer, etc.

Since the sample dryer of the present invention has the above-mentioned configuration, the drawer frame 3 is connected to the casing body 1.
When the sample is put in the drying box 2 and the drying box 2 is inserted into the insertion hole 3b, the packing 2c of the flange 2b of the drying box 2 is compressed by the weight of the drying box 2 and the weight of the sample. Eliminate gaps.
When the drawer frame 3 is pushed into the casing body 1, the drawer frame 3 smoothly enters due to the action of the rail 3d and the pulley 4, and the rail is pushed in with the front plate 3a of the drawer frame 3 and the front wall 1a of the casing body 1 in contact with each other. The position of the drawer frame 3 is lowered by the action of the recess 3d' provided at 3d, and the drawer frame 3 is pressed onto the packing 5a on the flange 5, and the back side of the front plate 3a of the drawer frame is also attached to the front wall 1a through the packing.
As a result, the inside of the casing body 1 is hermetically separated into an air supply chamber 6 and an exhaust chamber 7 by the drawer frame 3, and the two communicate only through the perforated plate at the bottom of the drying box 2. Become. In this state, the heater 8 and the blower 9 are turned on, respectively.
Dry samples effectively.

The sample dryers of this invention can be stacked as shown in Figure 1, and multiple pieces can be stacked up and down.
A horizontal arrangement is also possible.

(Effects) Since the present invention has the above configuration,
The drawer frame with the drying box can be pulled out smoothly, and the drawer frame and flange can be brought into close contact when the drawer frame is housed in the casing body, so ventilation to the drying box can be made efficient. There are other effects.
