Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a storage chamber wall that is provided at a bottom-side portion of the storage chamber wall due to the movement of the contained objects to expand outward as the storage chamber bottom rotates. A method for leading out stored objects such as seeds in a direct seeding machine, which allows the stored objects such as seeds stored in a storage chamber to be smoothly and easily led out from the leading-out holes, based on sequentially leading out the stored materials from the leading-out holes in the storage chamber, and The present invention relates to a deriving device used in the method.

(Conventional technology) For example, in the case of rice cultivation, direct seeding of rice is an innovative cultivation method that can reduce costs and expand the range of cropping seasons by omitting seedling raising and rice planting. In recent years, trial cultivation of direct sowing has been actively carried out.

In order to meet the demand for direct sowing, the present applicant proposed in Japanese Patent Application No. 63-270440 a seed ejecting device for a seeding machine for intermittently ejecting appropriate amounts of seeds stored in a hopper.

As the principle of this device is shown in FIGS. 12 and 13, this device is provided with a rotary plate C that rotates about its axis while keeping in contact with the lower surface of the bottom of a hopper a, and a The seed outlet hole e matches the regulation hole r as the rotary plate C rotates, so that an appropriate amount of seeds are intermittently extracted.

(Problems to be Solved by the Invention) However, in the device having the above configuration, the seeds near the bottom of the omper a are greatly affected by the pressure of the weight of the stored seeds. Therefore, the seeds existing at the lower end of the bottomed seed outlet hole g whose lower surface is closed by the rotary plate C are strongly pressed against the upper surface of the rotary plate, and as a result, the size of the seeds and the coating on the seed surface are affected. Depending on the state, the seeds may become partially or completely trapped in the small gap i between the bottom part d and the rotary plate C, and the coating on the seed surface and the seeds themselves are likely to be damaged. There was a problem.

As a result of careful consideration of such problems, the inventor of the present invention found that as long as the conventional ejection method of ejecting the contained objects from the outlet hole provided at the bottom of the storage chamber is adopted, the influence of the weight of the contained objects can be eliminated. As a result of extensive research, we concluded that it is virtually impossible to It was discovered that the stored items could be smoothly brought out without being affected by pressure.

The present invention has been completed by further developing this knowledge, and aims to provide a method for extracting stored materials such as seeds in direct tin, and a extractor for use in the method.

In FIG. 11, a blower device 11 in which a fan rotates in a horizontal plane is arranged slightly below the bottom of the container, and the high-speed rotation of the fan is controlled by a drive shaft 25 that rotates a rotary bottom plate 19 and a transmission device 102. A required number of air exhaust ports 10 are provided around the casing 103 that covers the fan.
4 is provided, and a contained material delivery pipe 105 is attached to this air outlet 104, so that the contained material discharged from the storage chamber is air-transported by the air fed from the air discharge port 104. With this configuration, it is possible to make the %6i1F more compact.

(Effects of the Invention) The present invention employs a basic configuration in which the bottom of the storage chamber is rotated, the wall is fixed, and the lower end of the wall is provided with an outlet hole for the stored items. When the bottom part is rotated in this state, the stored items are automatically pushed outward as the bottom part rotates, and the stored items can be easily and smoothly led out from the storage and ejection hole.

Therefore, the rotary plate provided with the regulation hole is placed in contact with the lower surface of the hopper bottom provided with the outlet hole, and as the rotating plate rotates, the regulation hole and the outlet hole match, and the contained material is discharged. Unlike the above-mentioned conventional apparatus, problems such as damage to the surface coating of the seed world due to the weight of the stored material, or damage to the stored material such as seeds, etc., do not occur.

If the outlet hole provided in the storage chamber is opened into the temporary storage chamber, the contents drawn out into the temporary storage chamber will be removed through the upper and lower discharge holes as the bottom of the temporary storage chamber rotates. Due to the coincidence, the scales will be discharged intermittently.

In particular, if a storage chamber is provided with an object receiving section provided with a through hole for falling objects at the lower end of the storage chamber, and the storage chamber is divided into two into a main storage chamber and a sub-accommodation chamber by this storage chamber. In the meantime, most of the weight of the stored objects in the storage chamber is supported by this object receiving part, so that the objects dropped into the sub-containment chamber are not affected by the pressure exerted by the weight of the stored objects. It is possible to spread outward without any force with almost no damage, and even if the stored object is easily damaged, it can be smoothly and effortlessly led out from the stored object outlet hole.
