Abstract

PURPOSE:To improve a conveying efficiency of articles, by continuously connecting links with pins, each link being formed with an arc at a lower portion along a longitudinal direction thereof, and thereby forming a waved concave surface on a conveyor surface. CONSTITUTION:A link 1 has an inner circle 2 of about 40cm radius and an outer circle 3 of about 44cm radius which is a concentric circle of the inner circle 2. The link 1 is formed at its longitudinal end with a male portion 4 and at the other end with a female portion 6. The male and female portions 4 and 6 are formed with pin holes 5 and 7, respectively. Thus, the link 1 is formed in a generally arcuate shape. The inner circle 2 is positioned outside a line P connecting the pin holes 5 and 7 by a distance L. A plurality of links 1 each having a generally arcuate shape are connected to form an endless belt, thus forming a waved concave surface on a conveyor surface. Accordingly, a conveying efficiency of articles may be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION - Industrial Application Field The present invention relates to a link chain that has a wide range of uses, such as for transmitting power, transporting articles, crushing articles, and dewatering.

・Prior art and its problems A typical cheno has a structure in which both types of link plates and roller link plates are connected continuously with pins, and is used for power transmission or conveyors, etc. Machining requires precision, it is expensive, the sprocket for driving the chain is expensive, lubrication is required,
There are problems such as the fact that it cannot be used directly for crushing articles, dehydration, etc.

・Purpose of the present invention The present invention is proposed in view of the above points, and its purpose is to be able to be manufactured at low cost, have the same performance as a ceno, and be suitable for conveyor, crushing, dewatering, etc. The objective is to provide a link chain that can be used directly.

・Structure of the present invention The present invention, as a technical means to achieve the above object, continuously connects links forming an arc at the lower part of the longitudinal direction with a bottle to form an endless shape. A concave part with the same curvature as the arc of the link is spanned between rotors that are continuously machined into a wave shape, and this is used for rotation transmission, for transporting goods, for crushing, dewatering, etc. It is something.

When an arc is formed at the lower part of the link in this way, the arc of the link itself engages with the four parts on the rotor side, making driving possible. In addition, by arranging link chains side by side in the horizontal direction to form an endless belt, a link chain belt surface can be formed.
By forming a continuous concave curved surface on the belt surface, it is possible to improve the conveyance ability when conveying articles, especially powder and granular materials, and it is also possible to design a large conveyance angle.

In addition, by pressing a pressure roller against the endless strip surface and inserting an article between the pressure roller and the endless strip surface, it is possible to crush the article, squeeze the article, crush pulp, etc. with high efficiency. be able to.

ΦEmbodiment Figure 1.2 shows a link of a link chain according to the present invention, which has an inner circle 2 with a radius of 40 cm and an inner circle 2 with a radius of 40 cm.
It has an outer circle 3 with a radius of 44 cm, and has a male part 4 at one longitudinal end and a female part 6 at the other end.
, and each part 4.6 is provided with a bottle hole 5.7, so that the whole is in the shape of an arc.

Note that the inner circle 2 is located outside (L) of the line P connecting the centers of the left and right bottle holes 5.7. Further, the inner circle 2 may not be a circle but may be a straight line depending on the application.

Fig. 3.4 shows a state in which the links 1 are connected continuously using the bin 8, and Fig. 5 shows a state in which the links 1 are connected continuously using the bins 8, and Fig. 5 shows a state in which the links 1 are connected continuously and spanned between the left and right rotors 9 and 10 to transmit power. This is an example of a link chain for use.

In the embodiment, the structure of the rotor 9.10 is such that the rotor 9.10 has a bottle hole 5 on its circumference having the same radius as the outer circle 3 of the link 1.
．． This is a configuration in which concave curved portions 11 having a length smaller than the distance between the two concave portions 7 are continuously formed.

Figure 6.7 shows the rotor 9 with link chains arranged horizontally.
．． FIG. 8 shows an example in which a link chain is used as a dewatering device.

In FIG. 8, a link chain arranged in an endless band is spanned between the left and right rotors 9 and 10, with the middle hanging down, and a pressure roller 12 is pressed against this from above. When the pressure roller 12 is pressed against the link chain surface in this manner, the link chain changes from a continuous wave-shaped surface to a circular curved surface close to concentric circles with the bin 8 as the center. As a result, the pressing roller 12 becomes inscribed in a circle with respect to the changed inner curved surface of the link chain, and the pressing surface becomes wider.

13 indicates a guide rotor. In addition, when using the link chain according to the present invention as a dehydrator, it is preferable to provide a relief angle Q as shown in FIG. 2 (b), and further provide a small gap P between adjacent parts.

-Effects of the present invention As described above, in the present invention, links having circular arcs in the longitudinal direction are successively connected by bottles to form a link chain, so the following effects can be expected.

a. Since the link consists of a single body, it can be easily manufactured by guicasting, casting, machining, etc. depending on the material.

b. Since a link chain or an endless belt can be constructed by simply connecting the links with bins, it is easy to manufacture a link chain or an endless belt chain, and the cost is very low.

When the entire C0 is connected to form an endless belt with arc-shaped links, and this is applied to a conveyor, a continuous wave-shaped concave curved surface is formed on the conveyor surface, which improves the conveyance efficiency of articles and also prevents steep angles. It is also easy to transport goods.

d. By positioning the inner circle of the link outside the center of the left and right pin holes, it becomes stronger against tension.

e. The link chain can be made into an endless strip and a pressure roller can be pressed against it to use it as a crusher or dehydrator. In this case, the deformation of the link chain expands the pressure contact surface, so the crushing or squeezing efficiency is improved. As the nail penetration rate improves, Q' becomes smaller in FIG. 8, and the nail penetration rate also improves.

f. By adding relief angles to the left and right sides of the link, the liquid drains very easily when dehydrated.
