(Prior Art) As a conventional material applicator, Utility Model Application No. 56-150308 (Prior Art Example 1) filed by the present applicant is known. The idea is to horizontally install a wide tank with a roughly V-shaped cross section in side view behind a boom equipped with a digging blade, and a discharge pipe is installed at the bottom of the tank, and organic matter is removed inside the tank by a feeding blade. It is moved from left and right and forced to fall.

In addition, conventional examples include "Rice husk underdrain method and device" (Japanese Patent Application Laid-Open No. 52-14044, Conventional Example 2);
“Deep fertilization device in fertilizer spreader” (1986-
147808, Conventional Example 3), "Fertilizer in Trencher" (Utility Model Publication No. 50-415, Conventional Example 4), and "Manual Spreader" (Utility Model Publication No. 55-131612, Conventional Example 5) are known. . Conventional Example 2 is a rice husk culvert device characterized in that a trenching chain that is driven and rotated is installed at the rear of a power moving machine so as to protrude downward, and a rice husk supply tank is attached to the rear of the trenching chain. ”
Pertains to. Conventional Example 3 is a "deep fertilization device for a fertilizer spreader, which has a fertilizer feeding funnel protruding downward from a hopper, and a groove-cutting device installed at the front of the funnel so that the depth and shallowness can be adjusted freely." It has a conveyor that moves the fertilizer back and forth inside the hopper.

Conventional Example 4 is configured such that the part of the trenching device 2 located on the rear side in the direction of travel of the trenching chain 2d is configured to rotate from below to the top, and the drop opening is located in the direction of travel of the trenching chain 2d. A fertilizer application device for a trencher, in which a compost pipe of a fertilizer application device 5 extending into a region located on the rear side is attached to a trencher beam 2b of a trench excavation device 2 so as to be vertically adjustable.
Consisting of

Conventional Example 5 is characterized in that a tilling device is arranged in series on the fertilizer release side, a fertilizing device is arranged near the tilling device, and a seeding device is arranged near the tilling device. It consists of ``Many Spretzder.''

(Problem to be solved by the invention) However, in Conventional Example 1, the problem of causing bridging at the droplet is caused by kneading the material to be spread, such as organic matter, such as compost, by the compression action or stirring action of the feeding blades. I had it. however,
In Conventional Example 2, "immediately after the trench 29 is dug, rice husks fall from the lower mouth of the tank 20 and are filled, as shown in FIG. to create a rice husk culvert.
In Conventional Example 3 as well, a fertilizer feeding funnel is provided behind the trencher separately from the trencher, and a reversing conveyor is provided above the funnel, and the conveyor is connected between the funnel and the reversing conveyor. is installed to guide the fertilizer transported by the conveyor to the funnel.

"Rice husk underdrain device" described in Conventional Example 2 and Conventional Example 3,
In both "deep layer fertilization devices in fertilizer spreaders," the material to be spread is not supplied to the upper part of the excavation body, so the soil is partially excavated and the material to be spread, such as fertilizer, is supplied to the soil in the excavated area. It was not suitable for the work of uniformly mixing. In addition, both methods aim to create a layer of material to be sprayed in the soil, such as by creating a ``culvert'' or a ``deep layer,'' which prevents the excavated soil from being mixed with the material to be sprayed again. It is not intended as a purpose. In Conventional Example 3, since the conveyor is only arranged in the front-back direction, it is not suitable for conveying fertilizer onto a trencher which is generally narrower in the width direction than in the movement direction.

In Conventional Example 4, since the fertilization pipe is made of a pipe, it is suitable for dispersing powdery fertilizer, etc., but has a problem in that it becomes clogged with organic compost and is difficult to supply.

In Conventional Example 5, the material to be spread does not fall directly onto the tillage device, so there was a problem in that the tilled soil and the material to be spread were not sufficiently mixed.

(Means for Solving the Problems) This invention consists of an excavation device installed on the side of the material applicator and rotatably driven in the front-rear direction and up and down;
A material to be spread, characterized by comprising a conveyor that conveys material to be spread in the width direction of the material application machine, and has one end installed directly above an excavation device, and supplies the material to be spread to one end side. We solve the conventional problems by providing application machines.

(Function) When the excavation device is driven, the soil is sequentially excavated by the excavation device installed on the side of the material applicator in the traveling direction of the material applicator. When the conveyor is also driven, the material to be spread is sequentially supplied directly above the excavation device located on the side of the material applicator. At this time, the material to be spread falls into the soil at the falling speed and is mixed therein, and the rotationally driven excavator supplies the fertilizer to the excavated area while mixing the fertilizer or the excavated soil.

(Example) The present invention will be explained based on the drawings. Figures 1, 2, and 3 are partially cutaway front views of the present invention;

Then, the floor conveyor 4 and the drive sprocket 9 of the excavation equipment are driven through the transmission path as described above, and the organic matter and other fertilizers transferred by the floor conveyor 4 are delivered to the excavation equipment through the wide supply port 6 arranged on one side. It falls forward and upward, is mixed in with the excavation equipment at the same time as it is being excavated, and is evenly mixed into the excavation ridge. Furthermore, since the supply amount can be adjusted, it can be used for a variety of purposes. The benefits are great.

(Effect of the invention) Therefore, in this invention, an excavation device is installed on the side of the material applicator and is driven to rotate in the front-rear direction and up and down, and the material to be spread is conveyed in the width direction of the material applicator. The excavating material applicator consists of a conveyor, which has one end installed directly above the excavation equipment, and a conveyor that supplies the material to be spread.

Therefore, when the excavation device is driven, the soil is sequentially excavated by the excavation device installed on the side of the material applicator in the traveling direction of the material applicator. When the conveyor is also driven, the material to be spread is sequentially supplied directly above the excavation device located on the side of the material applicator. At this time, the material to be spread falls into the soil at the falling speed and is mixed in, and the rotationally driven excavation equipment mixes the fertilizer or the excavated soil and supplies it to the excavated location.
As a result, the material to be spread is evenly mixed into the excavated area, and even when spreading organic compost, problems such as bridging caused by constriction at the bottom of the tank, which were observed in conventional methods, occur. The predetermined amount is mixed without fail.
