Abstract

PROBLEM TO BE SOLVED: To attain uniform mixing and prevent plugging of a mixing part and damage to baffle members by composing a mixing device body of a cylinder body provided with collision slip-off plates inclining inward, at specified spaces, and providing baffle members inside the cylinder body. SOLUTION: A mixing device body 1 is provided as a cylinder body 106 between first and second belt conveyors of a continuous mixing treatment plant. The appropriate number of collision slip-off plates 2 are integrally provided in the cylinder body 106 along the inner periphery in the state of inclining toward the center of the inside. Charged material therefore slips down easily toward the center of the inside. Inside the cylinder body 106, flexible baffle members B3 are further fitted in a cantilever form to a fixed member installed at the inner peripheral wall of the cylinder body 106. The baffle members B3 are provided vertically at a suitable space in the longitudinal direction of the cylinder bode 106 and in such a way as to contain the collision slip-off plates 2 particularly at a part where baffle members B3, B3' are disposed in an intersecting state. Since the baffle members B3 are constantly vibrated, adhesion of solidifying material mixed earth or the like passing between the baffle members 3 is prevented so as to be able to mix sufficiently with efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field for producing a soil stabilized soil, and more particularly to a screen for removing large-size gravels in earth and sand, and a screen after passing through the screen. Untreated soil storage hopper, first conveyor belt conveyor for cutting and conveying earth and sand, solidified material supply unit for supplying a predetermined amount of solidified material to the soil conveyed by the first conveyor belt conveyor, and this solidified material The present invention relates to a continuous mixed treated soil plant comprising a second conveyor belt conveyor for transporting treated soil mixed with a solidified material in a mixing section.

[0002]

2. Description of the Related Art Conventionally, mixing of earth and sand with a solidified material has been performed by a backhoe, a stabilizer, a pug mill, a vibrating screen, or the like. However, all of these mixing methods are performed using mechanical or electric power. This is expensive and uneconomical in terms of equipment. When a vibrating screen is used, the screen may be closed depending on the size and shape of the particle size. Therefore, the working capacity is reduced, the degree of mixing of the earth and sand and the solidified material is reduced, and an operation of removing the earth and sand from the screen is required, which complicates the operation, interrupts the construction, and is economically disadvantageous.

A mixing method or plant which focuses on mixing by the natural fall of earth and sand instead of such a conventional mixing method by mechanical or electric power is known from, for example, Japanese Patent Publication No. 6-17571. In this known method and plant, in order to avoid the above-mentioned disadvantages, the mixing damper is constituted by a front plate orthogonal to the center line of the conveyor belt conveyor, and the material of the front plate is projected. In the direction of hitting and flowing down, and at the center of the front plate body, there are provided two substantially square baffle members as viewed from the side. Further, in this known technique, a bar is provided for the same purpose.

[0004] In such a baffle member and the bar, the material layer which abuts on the baffle member and the bar is cut or sheared, and the earth mass is broken and thereby homogeneously mixed. However, since these members are fixed and immovable, the material simply collides with them and is destroyed, only passing through the gaps between the members. It is not done, it stagnates between the gaps, and even in the case of flat earth and sand, it may even cause clogging. In addition, there is a possibility that even the baffle member and the bar are damaged.

[0005]

The problem underlying the present invention is to avoid the above-mentioned disadvantages in a plant of the type described at the outset. That is, instead of the conventional mixing method using mechanical or electric power, in mixing using natural fall of earth and sand, uniform mixing by the flexible member and clogging of the mixing section can be avoided. And to prevent breakage of the baffle member and the bar.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided, in accordance with the present invention, a mixing device body comprising a cylinder body having an inwardly inclined impingement slide plate formed at an appropriate interval and in an appropriate number. The problem is solved by providing the obstruction member inside the body. In order to increase the mixing efficiency, in the present invention the baffles are provided in an orthogonal and parallel manner.

The baffle member according to the present invention is a flexible member such as a leaf spring, a rod, a chain, a wire rope or the like, which is fixed at both ends by a spring. Hereinafter, the present invention will be described in detail with reference to embodiments of the invention illustrated in the accompanying drawings.
