Abstract

PURPOSE:To convert the rotational motion of vanes into centrifugal flow inertia of a body without any loss by arranging plural rotary vanes in such a manner as disposing plural synthetic widths eccentrically. CONSTITUTION:Plural rotary vanes are arranged in such a manner as eccentrically disposing vane forms based upon a synthetic sine curve and vanes 6-1 to 6-6 having effective widths on the basis of concentric circumferential edges 6 having an arbitrary radius around a rotary shaft 1. When rotary vanes throw out bodies outward from their central parts, vanes are hardly subjected to shock resistance applied to them from view of vane form curve structure applied to vanes 6-1 to 6-6 and method of arrangement and mounting, thus the force for rotating vanes acts as it is to promote the centrifugal flow inertia of bodies.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for conveying various industrial materials using various forces such as direct centrifugal inertia 1 generated by single-rotation blades or wind power. be.

(Conventional technology) Nowadays, various objects can be controlled by the rotational force of two blades.

There are many devices that transport objects directly or by the wind force generated by them. Most of the force sucked and discharged by these devices is generated or caused by the rotation of the two blades as the two blades rotate. Due to the centrifugal flow inertia of the object or air (hereinafter simply referred to as the object), much of the two-rotation resistance friction is concentrated on the blade itself, as well as on its outer end and peripheral wall. Therefore, the strength of the force for suctioning and discharging an object is roughly proportional to the rotational speed, so if you want stronger force, you tend to go for higher speed and greater power.

Therefore, there is a need for improved technology to reduce the rotational speed and required power.

(Problems to be Solved by the Invention) The present invention has been made in view of two or more circumstances and aims to improve the technology thereof. The gist of the invention that forms the basis of the invention is
No. 3-967 was filed.

In illustrating the vane shape of the rotating blade featured in the previous application, an approximate curve based on a two-synthetic cycloid curve expression was used, but it is more certainly intended that a sine curve illustrative method be used thereafter. It turned out that it could be made closer to the shape of a feather.

This application relies on it.

This application is based on the trial study based on the previous application, and includes the following: the target object, the expansion of the range of applications, how to combine the curves that make up the wing shape of the blade, and how the rotation speed should be depending on the usage type, etc. This application is for improvements and expansions based on the features of the previous application.

(Means for Solving the Problems) The present invention provides rotary blades used in devices for conveying various kinds of objects, each having a nine-composite sinusoidal vane shape.

The basic structure is to have a plurality of vanes with an effective width arranged eccentrically.

(1) The structural diagram of the basic vane blade shape is shown in Figure 1, and the basis thereof is as follows.

The general formula of the basic composite sine curve is shown as y - As1n CBx)...■.

A method of superimposing the tangent of the curve at point A (blade base, which varies between OADs in relation to the eccentricity) of the vane shape and the necessary width created in this way on the tangent of the circle around the axis of one rotation. In order to improve the efficiency of each device, the blades are arranged and fixed at a plurality of locations.

In addition, the radius (eccentricity) of the circumferential circle of the rotating shaft that forms the base of the vane blade base should be determined through careful consideration, as the relative relationship is large depending on the target object, purpose of use, and device. be.

The above are the two basics of the present invention. Claims Paragraph 1 (
This is an explanation of the means related to (hereinafter simply referred to as "No. 2").

(2) An example of use regarding item 2 is the serial type conveying device shown in Figure 4.5.6 of the first drawing.

(3) Examples of use related to item 3 are various suction type conveyance devices shown in Figures 7, 8 and 9 of the nine drawings.

(4) An example of use regarding items 4, 5, and 6 is the serial conveyance device shown in Figures 10, 11, and 12 of the two drawings.

(Function) The function of the projection mentioned above is shown in Drawing 2. The nine wings shown in Fig. 3, which have a characteristic curved structure, function synergistically with the flow inertia of the object that accompanies the rotation of the two wings.

In other words, in the case of a device in which a five-rotation blade emits an object outward from its center (section 3 type), as shown in Figure 2, the blade-shaped curved structure and arrangement of the blade are Since the impact resistance against the two blades is extremely low, the rotating force of the two blades directly acts to promote the centrifugal flow inertia of the object, and the point of force P that releases the object is the outer end C of the two blades.
Since it is far from point P, the shearing force of the object is small and the resistance friction against the outer peripheral wall is also small.The force to release the object is concentrated at point P.The example equation is rotational moment Δ1. Weight of transported object G
If the distance from the shaft center to the point of force P is r..., then M-Or holds true.In this way, the rotational energy of the blade is directly converted into the centrifugal flow inertia of the object and promotes it.

Since momentum and inertia are imparted to the ejection of the object, the relative suction force becomes stronger, and efficiency is improved by the effect of synergistically increasing the suction and ejection force.

In addition, in a device in which rotating blades suction and discharge cutting objects in series (paragraph 2, 41 type), as shown in Fig. 2, the side end point C of the blade cutting the object and the discharge point Because the point P where the force is concentrated is far away, it is impossible to bite the object.

As described above, the rotary vane has the characteristics described in item 1, which mainly takes advantage of the centrifugal inertia of a relatively heavy object, which increases the force released together with the air flowing from the base. I have explained that there are two main types of usage, but as pointed out in the previous section (means), it is natural that there are subtle differences in the requirements for configuring the blades depending on the usage type. . Furthermore, there is a degree to which it is connected to its rotational speed when used.The front type can be fast depending on the degree of force required to be released, but the rear type has a speed at which the wind force is applied at the position where it bites into the object. It is necessary to consider the requirement that the amount must be kept to a level that does not interfere with the biting.

(Embodiments) Hereinafter, embodiments according to the present invention will be described in accordance with the preceding section of means and effects with reference to the drawings.

The rotating blade rotates. When an object is thrown in from 4, the outer end of the blade takes it in without any force, and it is ejected from \5. It should be understood that the rotation of the blade efficiently functions to bite into the object, convert centrifugal flow inertia, and provide ejection force, as shown in FIG. 3 and explained in detail in the operation section.

In this example, if the wind force generated is too strong (rotation is too fast), the biting from 4 will be hindered, so
Appropriate rotational speed is required.

This is a simplified device that rotates at a relatively low speed and is suitable for transporting heavy objects without relying on wind power.

I want to be understood because I am

In this example device, the direct resistance associated with the rotation of the nine blades is small even when the target objects are different, including air, objects that are integrated with air, and objects with high density such as water.

Since the energy of the rotation of the blades is directly converted into the centrifugal flow inertia of the object, it is easy to obtain high-speed, high-pressure conveyance effects. There are multiple fields of use.

(1) In the apparatus shown in FIGS. 10 to 12, nine rotary blades are rotated in a set direction by engine power of nine. When an object is supplied to the dissolved arc, it is cut by the outer end point C of the blade, is easily held by the blade, rotates, and is released from 5.

This example is an example of the use of a device specifically for the purpose of moving and conveying small snow or compost, but since the shearing force of the object at the outer end point C is small, it is easy to bite into a large cross-sectional area. It is. Centrifugal flow inertia is applied to the held object and it is smoothly released. In addition, since the object in this case can be bitten easily, there is little need for forward force to bite the object, so by providing a bridge section only for manual movement and holding the aircraft.

The device can be operated easily and is simple and convenient.

This makes it possible to downsize. Suitable for moving and conveying large-volume objects.

(Similar to example 11, if the wind force generated by the rotation of the blades is too strong, it will hinder the biting of the object, so a moderate rotation speed is required.) Also, this device can be used as an attachment for a tractor, etc., and only for a working machine. Of course, it can also be used in structures.

(Effects of the Invention) Several usage types have been described above, and in all cases, according to the present invention, due to the characteristics of the two-rotation blade structure, there is little resistance to the blades as the blades rotate, and the rotational movement of the nine blades is It is converted into centrifugal flow inertia of the object without waste, and suction, biting and ejection are performed efficiently.

Therefore, compared to conventional devices, the efficiency proportional to the rotational speed is greatly improved, so that the required power can be significantly reduced. Furthermore, compared to the required power, it becomes easier to transport at higher speeds and higher pressures, or to move large quantities of objects.

Considering the fact that a large number of conveying devices using a single-rotation blade mechanism are used in today's industrial activities, the effect of expanding the scope of use and improving efficiency is significant, and the effect of cost reduction is also significant.
