The trash plate having sufficient rigidity to withstand the soil pressure thereagainst and sufficient flexibility under said pressure to inhibit the adherence of soil thereto.，下面是Flexible plastic trash plate for a moldboard plow专利的具体信息内容。
1. A flexible trash plate attachment for fixed securement adjacent to the upper portion of the moldboard of a moldboard type plow that is adapted to be propelled through the soil, said attachment having a smooth soil engaging surface and formed of a flexible plastic material and of a shape, size and thickness such that it has sufficient rigidity so as to implement inversion of the earth worked by, the moldboard plow and is adapted to flex under the pressure of soil engagement to inhibit the tendency of soil to adhere thereto.
2. A trash plate for a moldboard type plow comprising: a. a plate formed of plastic material; b. means for fixedly mounting said plate juxtaposed to the moldboard of a moldboard type plow, at least partially in the path of earth worked by the tool; c. said plate having a curved soil engaging surface of a shape, size and thickness to provide sufficient rigidity so as to implement inversion of the earth worked by said moldboard type plow but permitting sufficient flexing in response to earth pressure so as to inhibit adherence of material thereto.
3. A trash plate formed of plastic material and fixedly mountable such that it is juxtaposed to the moldboard of a moldboard type plow at a location to positively engage the furrow slice as it emerges from the moldboard of the moldboard type plow, said trash plate functioning as a moldboard extension and having a face for slidably pressing against a furrow slice of soil formed by such bottom to implement inversion of such slice, Said face of the trash plate being smooth and said plate having a shape, size and thickness to provide a character of rigidity so as to implement inversion of the earth worked and a character of flexibility making it susceptible to flexing in response to variation in the furrow slice pressure to a degree inhibiting adherence of soil to such face.
4. The combination with a moldboard type plow including a moldboard having a generally horizontal upper edge, a flexible trash plate attachment fixedly secured to the moldboard and formed of relatively thick plastic material, said trash plate having a smooth soil engaging surface, said flexible trash plate having a shape, size and thickness to provide sufficient rigidity so as to implement inversion of the earth worked but permitting sufficient flexing in response to earth pressure so as to inhibit adherence of material thereto, said trash plate having a lower portion of lesser thickness than the main body thereof extending downwardly from and rearwardly of said horizontal upper edge of the moldboard and forming with the upper portion of the flexible trash plate a shoulder adapted to engage said horizontal upper edge of the moldboard.
5. A trash plate as set forth in claim 4, wherein there is a concavo-convex portion to define a concave side of the plate and the smooth soil-pressing face is concave and incorporated into the concave side of the plate.
