JP3028909U - Ventilation device for raw rice storage bag - Google Patents

Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: To insert a pipe, attach a fan to the upper end of the pipe, and forcibly suck in a ventilator, in which hot humid air sucked by the fan causes an exhaust port of the fan to pass through. There was a problem that when it passed, it was cooled and liquefied, and this was liquefied and dripped on the raw paddy in the container to wet the raw paddy in this part. SOLUTION: In the above conventional ventilation device, a means is provided in which an exhaust pipe communicating laterally from an exhaust port of a suction pump is provided and a drain reservoir is vertically provided at the base of the exhaust pipe.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilator that prevents stuffiness due to a rise in temperature inside raw rice that is harvested by a combine harvester and stored in a large rice padding storage bag.

[0002]

[Prior art]

 In recent years, rice harvesting with combine harvesters has been carried out by temporarily storing the cut rice grain in a tank built in the combine harvester, and then storing a large amount of rice grain of 700 to 1,000 kg, for example, a diameter of 1,200 cm and height. A method has been adopted to improve harvesting efficiency by transferring to a large 1,300 cm large paddy storage bag (hereinafter referred to as "container").

Then, the container filled with the cut rice grain is carried by a truck or the like into a drying facility of the home or a rice center in the area to be dried and then stored. It was.

[0004]

[Problems to be solved by the device]

 Generally, the moisture content of raw paddy harvested in the field is as high as around 28%, and the container that stores a large amount of such high-moisture paddy is a container made of breathable material. However, since internal ventilation is hardly obtained, if the rice is left in the housed state for a long time, stuffiness in the center of the container causes stuffiness due to the internal temperature rise and the taste after rice polishing deteriorates. Not only does it cause discoloration and broken rice, but there is a problem that product value is significantly reduced.

This problem often occurs in rice centers and countries due to waiting for dryness during the agricultural season when a large amount of raw rice is brought in from each farmer.

In order to deal with this, the applicant of the present invention has previously provided a large number of pores having a size such that raw rice cannot pass from the upper surface to the bottom of the central portion of the container containing the raw rice. Invented a ventilation device with a structure in which a perforated pipe formed by inserting a perforated pipe was installed and a fan that sucks air inside the pipe was installed at the upper end opening of the pipe. Was done.

However, in the above ventilator, the hot and humid air sucked by the fan is cooled and liquefied when passing through the fan exhaust port, and this drips onto the raw rice in the container, We faced the new problem of moistening the paddy in this area.

[0008]

[Means for Solving the Problems]

 In view of the above-mentioned situation, the present invention adopts a means of providing an exhaust pipe that communicates laterally from the exhaust port of the suction pump and vertically arranging a drain reservoir at the base of the exhaust pipe. This is a solution to the conventional problems that have been found in the ventilation of.

A means for connecting a hose to the lower end of the drain reservoir and guiding the drain to the outside of the container was also used.

[0008]

[Embodiment]

 Hereinafter, an embodiment of the present invention will be described in more detail with reference to the drawings. In the drawings, 1 is a container main body, and 2 is raw rice stored in a container 1. Further, 3 is a pipe made of metal or hard plastic having an appropriate diameter, and at least the peripheral wall of the region where the pipe is embedded in the paddy 2 is provided with pores 3a having a size such that the paddy can not pass through. In addition to the multiple penetrations, an outer collar or the like is formed on the upper end side of the pipe to form a mounting seat 3b for the suction fan (F).

Further, 3c shows a basic shape having a tapered portion in which the bottom of the pipe 3 is gradually reduced in diameter to make a sharp end, and if necessary, a screw blade 3d is projected on the peripheral wall of the tapered portion 3c. (See FIG. 2B). Further, the bottom of the pipe 3 is not limited to the one having the taper portion 3c (not limited to that shown in FIG. 2A, a flat bottom, a flat bottom having a large number of pores penetrating it, or a bottomless one (both not shown). No.), but in the case of flat bottom or bottomless, it is necessary to stand upright in the container 1 before adding raw rice.

Then, the suction fan (F) mounted on the mounting seat 3b at the upper end of the pipe is moved in the direction of the arrow in FIG. 1 to bring both flange portions into close contact with each other, and airtightly with a separate bolt or the like. Although tightened, an exhaust pipe 4 having a constant length is connected to the exhaust port (f), and a drain reservoir 4a hanging near the base of the exhaust pipe 4 is airtightly connected. In this case, the drain reservoir 4a is preferably made of a transparent material such as glass or plastic that can be seen through from the outside, and the exhaust cylinder 4 has an outlet tube 4 that simply spills water liquid dripping outside the upper opening of the container 1. For the purpose of guiding to the above, it is preferable that the length exceeds the outer peripheral edge of the container main body, but if it is too long, suction resistance of air in the pipe becomes high, which is not preferable.

When the number of containers 1 that need ventilation at one time is large and the containers are arranged in a plurality of rows in close proximity to each other, it is advisable to project the exhaust pipes 4 sideways so that they are adjacent to each other. Since it is possible that the container is exposed to humid exhaust, or it may be an obstacle when handling the container, the exhaust pipe 4 on the tip side of the drain reservoir 4a should be gently tilted upward to open the drain with a small size. It is possible to maintain good harvesting (see Fig. 1).

Further, the present invention is configured such that a drain pipe 4b made of a soft hose or the like is provided at the bottom of the drain reservoir 4a in consideration of the capacity of the drain reservoir 4a and the liquefaction amount of the exhaust gas, and a large amount of water is continuously supplied. I also made it possible to handle the drain. In the figure, 1a is a column for supporting the container, which is provided on the outer circumference of the container, and 3e is a handle for embedding the pipe 3.

[0013]

[Effect of device]

 As is clear from the above description, the ventilation device of the present invention has an extremely simple structure and can be supplied at a low cost. By providing an exhaust stack and a drain trap in the container, it is possible to reliably wipe out the adverse effects of stuffiness of the raw rice stored in the container and to store the raw rice in the container for a long time, especially during the agricultural season. It is particularly effective in solving the conventional problems that awaited dryness in rice centers in Japan.
