It is connected to the rotary screw body for the display body so that the rotational force of the rotary screw body can be transmitted via the orthogonal conversion gear transmission mechanism unit, and accompanies the rotation of the rotary screw body of the earth and sand discharge plate for scraping out earth and sand and the like. When the movement of the display body and the movement of the display body accompanying the rotation of the rotary screw body for the display body are linked to drive the movement of the soil removal plate by the soil removal plate movement drive mechanism unit, the soil removal system discharges the soil. A structure for displaying the position of the soil plate as the position of the display body so that the position of the soil discharge plate in the drive frame portion can be recognized from the front surface. The scraping frame body, which is removed by the vehicle's sediment removal device and installed in the area of sediment that accumulates on the ground below it,
In the scraping frame main body, a soil discharging plate for scraping out earth and sand arranged in the width direction thereof, and
It is incorporated in the scraping frame main body, and the soil removal plate is moved between the rear side and the front discharge side in the scraping frame main body, and the earth and sand accumulated on the ground in the scraping frame main body by the scraping frame, etc. A rotary screw body screwed into the soil removal plate, a drive sprocket supported by the drive frame, a handle for rotating the drive sprocket, etc. When,
It is a position display device of the soil removal plate added to the soil removal system having
A driving bevel gear located at the end of the rotary screw body protruding to a position outside the drive frame portion, and a rotary screw body for a display body rotatably supported on the front surface of the drive frame portion. A quadrature conversion gear transmission mechanism including a driven captive gear attached to the end, and a
It is arranged on the front surface of the drive frame portion in the same direction as the rotary screw body for the display body, and can move in the same direction as the rotary screw body for the display body while restraining the base of the display body for position display. Display body support rail body to guide and
Equipped with
The rotation of the rotary screw body is connected to the rotary screw body for the display body so that the rotational force can be transmitted via the prime mover tooth gear and the driven umbrella tooth gear, and the earth and sand are scraped out. When the soil removal plate movement drive mechanism is used to drive the movement of the soil removal plate by linking the movement of the rotary screw body with the rotation of the display body and the movement of the display body with the rotation of the display body rotation screw body, the above-mentioned The position display of the soil removal plate in the soil removal system is displayed as the position of the display body, and the position of the soil removal plate in the drive frame portion can be recognized from the front. Device. The length of the rotating screw body for the display body to which the display body is screwed can be adjusted by the gear ratio between the driving captive gear and the driven captive gear, and the screw pitches of the rotating screw body and the rotating screw body for the display body. 2. The position display device for a soil removal plate according to claim 2. The position display device for a soil removal plate according to any one of claims 1 to 3, wherein the soil removal plate position display device can be retrofitted to the front surface of an existing soil removal system. The soil removal plate according to any one of claims 1 to 4, wherein the soil removal plate position display device does not require its own electric power by utilizing the rotational force on the soil removal system side. Position display device. The position of the earth removal plate according to any one of claims 1 to 5, wherein the end position spring is attached to the end position of the rotary screw body for the display body by removing the screw portion. Display device.
