Description

DETAILED DESCRIPTION OF THE INVENTION In order to improve the drainage effect, this invention
This invention relates to a rice husk discharging device in a trencher used for filling rice husks into trenches dug in a trencher.

A rice husk discharge device is known which has a structure in which a hopper is provided at the rear of a trencher body that is suspended from a tractor so as to be able to rise and fall, and the rice husks in the hopper are scraped up by a screw toward the outlet of the discharge pipe.

In this known device, the screw is moved to the tractor's P
Although it is driven by a TO shaft, it is necessary to install a transmission shaft etc. from the tractor to the trencher, and it is necessary to start rotating the screw without delay at the start and end of trench drilling. , it is necessary to stop,
If there is a delay in the opening and opening operation, there will be problems such as areas not filled with rice husks being crushed, or rice husks spilling wastefully onto the ground surface at the end of the trench.

Therefore, in this invention, a scraper is configured to drive the rice husks in the hopper toward the outlet of the discharge pipe in conjunction with the grounding operation of the drive wheel rolling on the ground surface, so that the groove is created by lowering the trencher. When the trench begins to be excavated, the rice husks are immediately discharged, and when the trencher is lifted up after the process, for example, the discharge of the rice husks is stopped and the trench is filled with rice husks without waste. It has been devised so that it can be done.

The concrete structure of the present invention will be explained based on one embodiment shown in the drawings.A trencher 2 connected to a power agricultural machine 1
The hopper 3 is installed at the rear in the direction of travel, and as shown in Figure 3, this hopper 8 has a large width in the left and right directions in the direction of travel, a short front and rear length, a deep top and bottom, and a bottom with a cross section. Hopper 3
A cylindrical discharge pipe opening 4 is provided at the center of the bottom, and a lid 5 that can be opened and closed is hinged.

A raking body 6 is internally supported on the bottom of the hopper 3 in the left-right direction, and the auger 6 is formed so as to have twist angles opposite to each other on the left and right sides from the discharge pipe opening 4, respectively.
A sprocket wheel 7 is attached to an auger shaft 6a projecting outward from one side of the hopper 3.

The front ends of upper and lower links 8 and 9, which are of the same length as each other, are pivoted to the upper machine frame 2a of the trencher 2 so as to be rotatable in the vertical direction, and thus two sets are provided on the left and right sides of the upper machine frame 2a. The left and right side plates 3 of the hopper 3 are attached to the rear ends of the links 8, 9.
A, 3b are pivotally connected, and a chain case 10 with a sprocket foil 7 inside is mounted on one side plate 3b of the hopper 3.
Further, the arms 11 are attached to the other side plate 3a, respectively.
At the front end of the chain case 10 and the front end of the arm 11, respectively,
Drive wheels 12 and 13 with spikes are pivotally supported, a sprocket wheel 14 is attached to the drive wheel 13 inside a cheno case 10, and a chenno 15 is wrapped between the sprocket wheels 14 and 7. Stoppers 16, 16 are provided on the upper surface of 2a to protrude below the left and right upper links 8, 8, respectively.

Therefore, when the trencher 2 supported by the left and right lower links 17, 17 and the top link 8 at the center of the upper part is lowered to the excavation work position as shown in Fig. 1, the left and right drive wheels 12, 13 are The drive wheels 12 and 13 rotate as the trencher 2 moves forward after touching the ground, and the rotation of the sprocket wheel 14°7 causes the raking body 6 to transport the rice husks in the hopper 3 toward the discharge port 4. Also, when the trencher 2 is lifted, the first drive wheels 12 and 13 are separated from the ground surface, so together with the hopper 3,
The upper links 8, 8, which are slightly downwardly inclined, are configured to be supported by stoppers 16, 16.

Therefore, hopper 3 is wide on the left and right, short on the front and back,
The top and bottom are deep, so the height is not too tall.
Therefore, charging the rice husks into the hopper 3 became extremely easy.

The rice husk discharging device in a 1-wrencher according to the present invention is configured as described above, and the scraping body 6 that scrapes up the rice husks in the hopper 3 toward the discharge pipe opening 4 is moved by a driving wheel that rolls on the ground surface. Since the first drive is performed in conjunction with the ground contact operation, for example, when the trencher 2 is lowered to open a trench at the start of one work process, the raking body 6 starts to drive and the rice husk is removed. In addition, when trencher 2 is lifted at the end of one working process, the discharge of rice husks will stop, leaving a part of the groove without chaff, or leaving a part of the groove outside the groove. There was no more waste such as rice husks spilling on the ground, and
Since the raking body 6 is driven at a speed proportional to the trench digging speed of the trencher 2, the trench is always filled with rice husks to a predetermined thickness regardless of the trench digging speed, and a uniform drainage effect is expected. It can be done.
