Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor soil hopper in a seedling floor soil supply device, and more particularly to a method for preventing a blockage of floor soil by vibrating a hopper side plate.

[0002]

2. Description of the Related Art Conventionally, there is a seedling container soil reversing device as a device for placing a paper cylinder used for seedling raising technology, filling floor soil, and then turning over. As a device for supplying floor soil to the seedling raising container soil reversing device, Utility Model Registration No. 3033572, "A device for supplying soil to a paper container container soiling device" is known. The floor soil hopper in the floor soil supply device is rectangular in plan view and gradually narrows downward, releasing the upper surface and the bottom surface, providing a discharge port at the front lower edge, and desiring the bottom surface at the center of the four-post frame. At the same time, the outlet is directed forward, and the outside of the middle of the four corners is supported by the upper end of the four-post frame, and is placed on the ground.

[0003] In the case of a hopper in which a granular material flows by gravity, it is an important problem to eliminate the blockage of the hopper. It is said that it is effective to reduce the cone angle and to apply vibration to the side plate to eliminate the blockage. Japanese Laid-Open Utility Model Publication No. 6-3345 discloses a floor soil hopper in which the cone angle of the hopper is reduced in order to prevent blockage. Each one provided with a vibrator is disclosed in Japanese Utility Model Laid-Open No. 5-46256. Further, there is also a device in which a stirring rod is provided to cross the middle portion of the floor soil hopper, and the handle is manually turned from outside the floor soil hopper to eliminate the blockage. Many farmers, on the other hand, hit the soil hopper to remove the blockage or agitate the hopper with a scoop.

[0004]

As described above, in the floor soil hopper of the floor soil supply device, reducing the cone angle of the hopper in order to eliminate the blockage in the hopper is to reduce the hopper floor soil storage. It is not preferable because the amount is reduced. Attachment of the vibrator to the side plate has a problem that a lot of cost is required for the apparatus. Providing a stirring rod that rotates manually in the floor soil hopper involves the trouble of rotating the stirring rod. Hitting the floor soil hopper or stirring the inside of the hopper with a scoop not only requires human labor but also has disadvantages such as deformation of the hopper. In view of the above circumstances, the present invention provides a flooring feeding device for raising seedlings that can prevent blockage by applying vibration to the side plate of the floor soil hopper with a relatively simple device without reducing the hopper capacity. It aims to provide a soil hopper.

[0005]

According to the present invention, a discharge port having a square shape in plan view, which becomes narrower toward the lower portion, has a top surface and a bottom surface open to a plane, and has a discharge port provided with a metering plate at a lower edge of the front surface. In a girder floor hopper, a motor is fixed to one of the side plates of the floor hopper, an eccentric load is attached to a rotating plate fixed to the output shaft of the motor, and the side plate on which the motor is provided faces the side plate. A rod is erected between the side plate.

Further, in the motor, it is preferable that the rotary plate provided with the eccentric load has a load attached by changing the amount of eccentricity from the center of the rotary plate.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The floor soil hopper of the present invention has a rectangular shape in plan view and becomes narrower as it reaches the lower part, the upper surface and the lower surface are opened to a plane, and a discharge port provided with a metering plate is provided on the lower edge of the front surface. Hopper made of thin steel sheet. In other words, the shape of the truncated cone is inverted. The capacity for supplying the soil to the nursery box is about 1. The capacity is determined in consideration of 5 cubic meters to 2.0 cubic meters, and the inclination of the side plate of the floor soil hopper is set to a cone angle of 75 degrees inside and outside. Make a square opening. The height of the floor soil hopper is about 1.2m so that the floor soil can be easily put in. Then, on the ground, the opening of the bottom surface is viewed in the center of the lower part of the four-post frame, and the four corners of the four-post frame are supported outside the four corners of the intermediate height of the hopper.

In order to apply vibration to the side plate to prevent the floor soil hopper from being blocked, a motor is fixedly mounted on the outer surface of a central portion of one of the side plates of the hopper and an eccentric load is fixed to an output shaft of the motor. Attach the rotating plate and apply vibration to the hopper side plate by the rotation of the motor. Furthermore, this vibration is transmitted to the opposing side plates to enhance the effect of preventing the blockage due to the vibration. That is, a bracket is provided on the inner surface of the hopper where the motor is mounted, a bracket is also provided on the inner surface of the hopper opposed to the inner surface of the hopper, and a rod is erected between the two brackets. The above-mentioned motor mounting position may be near the center of the intermediate height of the floor hopper side plate. In addition, the rod may be installed horizontally, or may be installed with a slight inclination up and down.

A rotary plate mounted on the output shaft of the motor has an eccentric load by screwing a bolt penetrating the center of the cylindrical weight at an appropriate distance in the outer peripheral direction from the center of the rotary plate to the rotary plate. In addition, a screw hole for screwing the bolt with an eccentric amount can be provided on the outer peripheral portion of the rotating disk so that the strength of vibration can be changed, and the mounting position of the cylindrical weight can be changed. To do.
