Abstract

PROBLEM TO BE SOLVED: To provide an automatic grain feeder causing no grain jam for a covered conduit laying machine. SOLUTION: This automatic grain feeder is provided with a tank 3 mounted in the covered conduit laying machine for storing unhulled grain m, a horizontal screw conveyor 4 conveying out the unhulled grain m inside the tank 3 to the outside of the tank 3 along the lower end of the tank 3, and a delivery passage 50 leading the conveyed unhulled grain m to a hopper 23. The delivery passage 50 is formed of a belt type horizontal conveyor 5, and a starting end 5b of the conveyor 5 is connected to a terminal end of the horizontal screw conveyor 4, while a terminal end 5c of the conveyor 5 is connected to the hopper 23. As the upper side of the conveyor 5 is opened, the unhulled grain m can be fed to the upper 23 without causing any jam even if it is solidified by high humidity or rainwater. The unhulled grain m can be visually observed on the conveyor 5, so that foreign matter can be removed easily.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically supplying granules of a culvert laying machine mounted on a culvert laying machine for forming a culvert such as rice hulls for improving drainage capacity of paddy fields.

[0002]

Conventionally, Japanese Unexamined Patent Application Publication No. 11-164628 discloses a self-propelled vehicle body that travels on the ground by means of an endless track or wheels. While advancing and digging a ditch, a drain pipe is provided at the bottom of the ditch, and the suction pipe is covered with rice hulls supplied from a hopper, and the ditch is buried back to lay a culvert. A tank for storing rice hulls, and a horizontal transport member for carrying out the rice husks in the tank to the outside of the tank along the lower end of the tank. And a vertical screw conveyor that guides the transported rice hulls to the hopper, and a telescopic bellows pipe-shaped connecting member connected to the upper end of the vertical screw conveyor and connected at the lower end to the hopper, and the rice stored in the tank. The transverse conveying member, the vertical screw conveyor, was to send out the hopper through a bellows pipe-shaped connecting member (herein paragraph 0006,0007).

[0003] However, in such a device, since the portion from the end of the horizontal conveying member to the hopper is formed by the vertical screw conveyor and the bellows pipe-shaped connecting member, the rice husk passes through the closed space. For this reason, when the environment is high humidity or rainy weather, the rice husks may adhere to each other and the rice hulls may be clogged by the vertical screw conveyor and the connecting member. Further, even when foreign matter is mixed in the rice husk, there is another problem that the rice husk moves in a closed space from the tank to the hopper, so that the foreign matter cannot be visually observed and removed.

Accordingly, the present invention solves the above-mentioned problems and eliminates the clogging of the granules from the tank to the hopper, and also enables the automatic removal of granules from the underdrain laying machine which can easily remove foreign matters and the like. It is intended to provide a device.

[0005]

In addition to installing a water absorption pipe at the bottom of the concave groove, the water absorption pipe is covered with grains such as rice hulls supplied from the hopper, and the groove is backfilled and installed on a culvert laying machine with a drain layer part that lays a culvert. Possible, a tank for storing the granules, a horizontal conveying member for carrying out the granules in the tank to the outside of the tank along the lower end of the tank, and a delivery path for guiding the carried out granules to a hopper, The delivery path is formed by a horizontal belt-type or screw-type conveyor, and the start end of the conveyor is connected to the end of the horizontal conveying member, the end of the conveyor is connected to the hopper, and the upper part of the conveyor is opened. Features A granule automatic feeder underdrain laying machine for.

According to the structure of the first aspect, the grains such as rice hulls can be guided from the tank to the hopper via the horizontal conveying member, the belt type or the screw type conveyor.

According to a second aspect of the present invention, there is provided the automatic granule feeding apparatus for an underdrain laying machine according to the first aspect, wherein a windbreak is provided on at least one side of the conveyor.

According to the configuration of the second aspect, it is possible to prevent the wind from hitting the grains such as the chaff on the conveyor.
