Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a vibrating screen, and more particularly to a vibrating screen with an improved drive mechanism.

[Conventional technology]

Conventionally, as this type of vibrating sieve, for example, Japanese Patent Publication No. 54-40791, etc. The one described in is known. In other words, a pair of adjacent oscillation means are placed on the left and right. and a synchronous reversing mechanism for synchronously rotating the oscillating means in mutually opposite directions. By connecting the synchronous reversing mechanism and providing a driving means at the input end of the synchronous reversing mechanism, was driven to generate linear or elliptical motion on the vibrating sieve.

0003 The oscillating means are provided as a pair in the longitudinal direction of the sieve frame of the vibrating sieve, and further in the opposite direction. A pair of similar oscillating means is provided in the longitudinal direction of the sieve frame, and the oscillating means is They are connected by a connecting shaft, further connected to the synchronous reversal mechanism, and the synchronous reversal mechanism described above. A drive means is provided at the input end of the rotation mechanism.

0004 When the drive means is rotated, the output end of the synchronous reversing mechanism rotates in the opposite direction to the input end. The oscillating means are rotated synchronously in opposite directions, or a pair of oscillating means are rotated in opposite directions. An excitation force is generated by the rotation of the unbalanced weight of the means, and as mentioned above, it is directly applied to the vibrating sieve. Giving linear or elliptical motion. In addition, the drive means, synchronous reversing mechanism, and connecting shaft described above are all arranged laterally from the sieve frame. It is located in an isolated location.

[0005]

[Problem that the idea aims to solve]

However, in the above-mentioned conventional vibrating sieve, the drive means constituting the drive mechanism, the synchronous reaction Both the rotation mechanism and the connecting shaft are located at a location spaced laterally from the sieve frame. This increases the required width of the vibrating sieve as a whole, and , which limits the use of space on the machine side.

[0006] In addition, since a synchronous reversing mechanism and connecting shaft are used, the weight of the vibrating sieve drive system is reduced. It is possible to achieve weight reduction, which is an essential task of vibrating sieves due to excessive weight. In addition, the drive means, synchronous reversing mechanism, and linking mechanism are installed in the machine side space of the vibrating sieve. In addition to the pedestal that supports the connection shaft, wiring for power supply to the drive means is installed to reduce interference. This results in a crowded arrangement of components, making it difficult to simplify the structure of the space on the machine side of the vibrating sieve. Not possible and not desirable.

[0007] The present invention solves these conventional problems, and its purpose is to improve the vibrating sieve. It is possible to avoid an increase in the width dimension, and it is possible to simplify the structure of the space on the side of the machine. The purpose is to obtain a vibrating sieve that can be used.

[Means to solve the problem]

This invention consists of two or more shafts that form an unbalanced weight between the side plates installed on both sides of the sieve frame. An oscillation means consisting of an eccentric shaft is installed, and a support part is installed near the oscillation means. driving means for constructing a material between the side plates and driving the eccentric shaft on the support member; This is what is listed.

[0009]

[Effect]

In the above means, drive mechanisms such as oscillation means and drive means are arranged above the sieve frame. Therefore, it is possible to avoid an increase in the width of the vibrating sieve, and the sieve frame of the vibrating sieve can be There is no need to install drive mechanism components on the outside in the width direction of the vibrating sieve. It is possible to have a simple structure between the two.
