Description

[Detailed Description of the Invention] The present invention is characterized by the premise 111 of the first term of the range of hj1°d.]
Regarding sieving as described in Section 4.

It is in the Federal Republic of Germany that the rods holding the thrust pieces and the swinging levers are supported rotatably around a vertical axis in a box, and that these rotary support pieces are configured as rubber torsion springs! 181-2016199. Additionally, the six rods can be oscillated by an electromagnetic drive, but this results in relatively low manufacturing costs.

Furthermore, all the +/1-way swinging rehakas that hold the thrust pieces are connected via a common pusher, and this 411′lL
Screening machines in which the rods can be vibrated via only one vibrator are known. As a vibrator, a crank transmission capable of being driven dynamically is provided, and the connecting rod of this crank transmission is pivotally connected to the push rod.

In this case, the sieving according to German Patent No. 2016199 requires a significantly reduced number of vibrators compared to the sieving method, and therefore also lowers the manufacturing costs, but also Regardless, in all cases, a connecting rod that is connected 1 inch and 1 is required, that is,
jj! It is possible to cancel the vertical vibration of the push rod that inevitably occurs when the 5-motion lever reciprocates, jj, and 6. Shake h instead of “-n device-”
It is necessary to install a salt drive device (t:I) as a device (it is also necessary in the case of

Furthermore, these known sieving machines have the following drawbacks: That is, the sieve part is tilted with respect to the woven fabric surface by the rods provided under the woven fabric surface and the rotating support pieces of these rods fixedly held on the stand, and the sieve part is tilted with respect to the woven fabric surface. - The part hits the woven fabric surface, and at this time, the sieve part is moved along the woven fabric surface while contacting the woven fabric, resulting in considerable sifting?!8(5i;j; wear).

The problem to be solved by the present invention is that claim t1 (premise 1 of clause 1,
As described in Section 1, the machine for the tl sieve was improved so that all the sieves holding the cut pieces were driven by a common vibrator through a common push rod. sifting by maintaining the advantages already obtained in the prior art, and further maintaining at least a quiet operation and reducing wastage (each sifting portion of the material is The advantage is that by better adapting the properties, manufacturing becomes easier and more controlled.

The solution to this problem has the following characteristics. That is, the bar holding the protrusion piece is provided at both ends, the sieve portion is provided along the surface of the woven fabric, and this sieve portion is green;
It is supported by vertically elongated bending springs made of gold 14 placed in a cylinder at least approximately the same as the plane II, and one end of these bending springs is placed in the box, and the other end is placed in the box. An electromagnetic vibrator is provided, the free end of which can be taken out in one series, and which acts on the pressed persimmon in a straight or triangular shape and is capable of adjusting the frequency and amplitude. (・ru.

By this means, the surface of the sieve has been protected to a degree that has not been reached until now. 3
・The sieve part can be installed at the same height as the woven fabric surface by using the 1111 single-piece, trouble-free and maintenance-free 1111-inch dust moving shaft that holds the dust particles, so the sieve part can be installed at the same height as the woven fabric surface. During the time the piece hits, the sieve size is approximately 1 to the woven fabric surface.
This sieve portion is directed to one corner and hits the woven fabric surface and 7
C) The sieve portion promotes wear on the woven fabric surface by t.
I., 7-) This is because the lateral component is calculated twice.

Furthermore, the elastic holding piece that holds the thrust piece enables direct connection between the vibrator and the push rod by reducing the conventionally required continuous wire (4" IJ6), resulting in a significant reduction in manufacturing time. Furthermore, with the above-mentioned 125. spring, a larger spring stroke can be obtained in the vertical direction than with the rotary support piece formed as a rubber torsion push spring, so that the vertical vibration of the push spring can be suppressed. In addition, the frequency and/or
The separation effect is enhanced by the change in amplitude, and the risk of clogging of the woven fabric surface by the sieve is also significantly reduced by the sieve. Furthermore, the electromagnetic drive M is cheaper than the rank transmission, which can be driven by an electric motor 7'.

In this case, it is advantageous if the free end of the flexure spring, which serves to attach the rod, is directed toward the material input, with the screen portion of the woven fabric facing toward the material input.

In particular, the above-mentioned sieve is configured to further improve the quiet operation of the machine, in which the bar is connected to the push bar via a swinging lever by means of a metal flexure spring which is attached to the push bar on the one hand and to the pivot lever on the other hand. It consists in being combined.

For this purpose, a 4-4 configuration, which is preferred and useful in the sense of the present subject matter, is such that at the free end of each oscillating lever on the push rod side, this oscillating lever is At least one spring oriented perpendicularly to the longitudinal extension of the lever is held approximately in the center of the extension, with each deflection 1. Both ends are held by the push rod of the lever in the same direction as the vertical extension 1ff of the pusher.
81.The other person was transferred to the liquid bank.81.
This makes it possible to eliminate rotary joints hitherto deemed necessary and subject to wear and tear (depending on the material used), and these rotary joints First, due to the expansion of the support single play 151 caused by 1i f+, the I bell sound level becomes slightly higher.

The above-mentioned 1. is useful for movable interaction between the pressed persimmon and the swinging lever. In order to exclude the shipper of the rice, it is advantageous to support the push azusa on the stand in almost the same direction as the swinging lever. Preferably, it has approximately the same effective length as the lever.

The guide piece is designed as a flexible rod which can be accessed on the one hand by the frame and on the other hand by the push rod and is oriented at right angles to the secondary extension of the push rod.

Another advantageous process of the above-mentioned object is that the 5-sieve part will prevent the vibration superimposition on the woven fabric surface.
The push rod consists in being supported movably only in the direction of the longitudinal extension of the push rod by the inside of the linear arm, which is fixedly held on the frame.

Embodiments of the invention are shown in the drawings and described below.
I will explain h51;
