Abstract

PURPOSE:To provide a fixed amount of transportation smoothly by forming a horizontal cantilever screw at a hopper lower part, being surrounded by an outer wall where there are provided radial receiving fittings on its inner surface, installing a rotating outer cylinder which has fins at a small inclining angle on the inner surface vertically, and disposing a screw which rotates in the opposite direction at its inside. CONSTITUTION:A cantilever screw 2 is provided at the lower part of a dust accumulating hopper 1, and several radial receiving fittings 3 in a mountain shape are protrudingly installed on the hopper inner wall surface 1b which surrounds the cantilever screw 2 in a central shaft direction of the screw 2. With this constitution, the divided force in a radial direction which is applied to a transported article by the cantilever screw 2 is eliminated, and only divided force in a thrust direction is applied for smooth transportation. Besides, a rotating outer cylinder 4 where a fin 5 with a small inclining angle is obliquely installed at its inner surface is disposed at the outlet edge of the cantilever screw 2 vertically or at a sharp inclination to provide a screw 7 in the rotating outer cylinder 4 and rotate the rotating outer cylinder 4 and the screw 7 in an opposite direction to each other.

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention consistently performs the process from storage of objects to upper level conveyance, and enables wide installation by installing the upper level conveyor vertically or at a steep angle. It concerns a screw conveyor that does not require space.

[Prior Art] Conventionally, a steep-angle screw conveyor that transfers objects such as garbage to a higher level vertically or at a steep angle is disclosed in Japanese Patent Laid-Open No. 62-2.
This method is described in Japanese Patent No. 05912, and the screw blades are fixed to the inner surface of an outer cylinder that rotates in the opposite direction to the screw shaft, but as a result of experiments, the screw blades are fixed to the inner surface of the outer cylinder that rotates in the opposite direction to the screw shaft. Even if the conveyor was reversed, it was difficult to smoothly raise the conveyed object.

[Problems to be Solved by the Invention] An object of the present invention is to provide a screw conveyor that is capable of transporting objects to be transported to high places in fixed amounts without any problems.

[Means for Solving the Problems] The means of the present invention is to arrange a cantilever horizontal screw at the bottom of a hopper for storing garbage, etc., and to attach a radial bracket to the inner wall surface of the hopper on the outer periphery of the horizontal screw. A rotating outer cylinder with its lower end connected to the hopper discharge port is installed vertically or at a steep angle, and a large number of rows of fins with shallow inclinations are installed diagonally on the inner peripheral surface of the rotating outer cylinder. A screw shaft is provided at the center of the outer cylinder, and the screw shaft and the rotary outer cylinder are connected to a rotating mechanism that rotates the rotary outer cylinder in opposite directions.

[Example] In the figure, 1 is a storage hopper, and a cantilever screw 2 is provided at the bottom of the storage hopper. This cantilevered screw 2 moves the support point to one side, opens the delivery port la side at the other end, and prevents it from interfering with the conveyance. Several metal fittings 3 are provided in the direction of the center axis of the screw 2, and the cantilever screw 2 is attached to the conveyed object.
The radial component of the force is canceled and only the thrust component is applied. In this way, it becomes possible to send out a fixed amount of the material to be transported. Reference numeral 4 denotes a rotary outer cylinder, the fixed inlet outer cylinder 14 at the lower end of which communicates with the outlet port 1a, and fins 5 having a shallow inclination angle are obliquely provided on the inner circumferential surface. (See the developed view in Figure 5) Then, a screw shaft 6 with a screw 7 is installed in the center of the rotating outer cylinder 4, and collars 11 are attached to the outer peripheral surface of the rotating outer cylinder 4 at several locations at predetermined intervals. The contacting guide trochanter 12 is attached to the support 1
It is pivotally supported by an outer cylinder mount 13 fixed to 6. The upper part of the rotary outer cylinder 4 is provided with an outlet outer cylinder 15 having a communication passage 51 communicating with an incinerator 50 and fixed to a support 16 . 10 is an electric motor for rotating the rotary outer cylinder 4 in the opposite direction to the screw shaft 6, 9 is its chain mechanism, 10' is an electric motor for forward rotation of the screw shaft 6, 9' is its chain mechanism, and 8 and 8' are the screw shafts. It is a bearing.

[Function] The rotating outer cylinder installed vertically or at a steep angle has fins on its inner peripheral surface that are inclined at approximately 30 degrees with respect to the central axis, so when these fins rotate in the opposite direction to the screw 7, , it is possible to transport small objects upwards and to transport them sequentially in a stable state without falling back.

[Effects of the Invention] According to the present invention, the storage of objects to be transported to upper-level transport is carried out continuously and automatically, thereby making it possible to transport the objects in a fixed quantity. In addition, space can be used effectively by installing vertically or at a steep angle.

By changing the rotation ratio between the rotary outer cylinder and the shaft, each gap, etc., it is possible to obtain a conveyor that can handle any size of conveyed object.
