Abstract

A vehicular automotive soil treating machine having a main frame structure provided on an automotive drive means to support thereon a soil feeding stage including at least a soil hopper and an additive hopper for feeding soil and an additive soil improving material, a soil processing stage including a soil processing trough which is internally provided with a mixing device for mixing soil and additive material while being transferred from one to the other end of the soil processing trough, and a processed soil discharging stage including a soil discharging conveyer for transferring processed soil of improved quality in a predetermined direction. The soil processing trough is provided with an inlet opening on the upper side of its fore end portion to receive soil and additive material therethrough, and an outlet opening on the bottom side of its rear end portion to discharge processed soil of improved quality toward the discharging conveyer.

Claims25

Dependent claims

An automotive soil treating machine, comprising:

a main frame mounted on a vehicular base carrier;
a first hopper provided on one longitudinal end of said main frame to receive soil to be processed;
a second hopper provided on said main frame in a position forward of said first hopper in a soil processing direction to receive a supply of an additive soil improving material;
a first conveyer provided on said main frame and adapted to receive soil and a soil improving material from said first and second hoppers and to transfer same forward in a longitudinal direction of said main frame;
a soil processing mechanism mounted on said main frame in a position forward of said first conveyer in said soil processing direction, and adapted to receive soil and additive soil improving material from said first and second hoppers and mix said soil and additive soil improving material uniformly with each other while transferring same substantially in a horizontal direction toward the other longitudinal end of said main frame;
a second conveyer provided on said the other longitudinal end of said main frame and adapted to transfer treated soil coming out of said soil processing mechanism further toward a predetermined dumping position;
and
a drive mechanism for said soil processing mechanism, supported on said main frame by means of a support member and at a position over said soil processing mechanism.

An automotive soil treating machine, comprising:

a main frame provided on a vehicular base carrier;
a soil hopper provided on said main frame to throw in soil to be treated;
a soil charging conveyer located beneath said soil hopper to receive soil and transfer same onward;
an additive feed unit including an additive hopper and a quantitative feeder and adapted to feed an additive soil improving material onto said conveyer at a controlled feed rate;
a soil processing mechanism mounted on said main frame in association with said soil charging conveyer, and provided with a mixing transfer unit within a soil processing trough, said mixing transfer unit being adapted to mix soil and additive soil improving material uniformly with each other while transferring same substantially horizontally through said soil processing trough;
a soil discharging conveyer provided on said main frame in association with a soil outlet end of said soil processing trough to transfer treated soil onward toward a predetermined discharging point;
a mixing ratio control unit adapted to control a feed rate of said additive soil improving material by said quantitative feeder of said additive feed unit according to a soil feed rate by said soil charging conveyer;
and
a drive mechanism for said soil processing mechanism, supported on said main frame by means of a support member and at a position over said soil processing mechanism.
