Abstract

THE METHOD OF PRESSING STEMPEL MATERIAL, including periodic material supply to the piston pressing chamber with the rear wall, creating a pressing force towards the rear wall, moving it away from the piston and wrapping the newly obtained bale of material, characterized in that reducing energy consumption when pressing bales of various sizes, the back wall is moved by an amount that is a multiple of the size of the bale to be produced, each movement being carried out before the start of the formation after. of the bale and after strapping the previous one.

Description

The invention relates to agriculture and can be used in pressing the stalked material, in particular flax.

A known method of pressing a stalked material, which includes feeding the material into a rectangular pressing chamber with a rear wall and a mechanism for opening it and creating a pressing force followed by wrapping the pressed material 1.

The method is known for pressing a stalked material, which includes periodically feeding the material into a piston type pressing chamber with a rear wall, creating a pressing force towards the rear wall, moving it from the direction of the piston and wrapping the newly produced bale material 2.

The disadvantage of these methods is the impossibility of obtaining bales of different sizes in one press chamber. The need to obtain bales (bales) with different sizes may arise, for example, when pressing flax, depending on the type of pressed raw material - flax straw and flax. Bales of flax seed should have a large mass of 500 kg or more, since they do not undergo a lobe operation, and a larger mass facilitates the mechanization of their loading to discharge. The flax fiber is operated on the flax plant, the result is that its weight increases 5-6 times when wet, and a bale weighing 500 kg after the lobe weighs 2.5-3 tons. The sizes of bales of flax straw are also limited by the size of my urinal chambers . Therefore, for pressing flax straw and flax straw, it is necessary to have two known presses, which leads to higher energy costs.

The purpose of the invention is to reduce energy consumption when pressing huks of various sizes.

This goal is achieved by the fact that the rear one is moved by the magnitude of the bale size of the bale produced, and each move is made before the formation of the next bale begins and after the previous one has been tied.

Pressing is carried out as follows.

The back wall is installed inside the bale chamber to the desired bale size (bale). The compressible material is fed into the press chamber and pressed to the rear wall. The compacted material is tied around, the rear wall is moved, and it is placed inside the bale chamber at the size of the bale bound or at the end of the bale chamber, if the bale size is half the length of the chamber. In this case, the back wall is displaced by a whole width multiplied by the size of the bale in the direction of the pressing force. The pressed material is then fed back into the bale chamber, the bale being pushed all the way into the back wall.

If more than two bales of the required size are placed in the bale chamber, the rear wall is rearranged along the length of the gauge, and the material is further pressed and wrapped. The rear wall is rearranged until it is at the exit end of the bale chamber. In this position, the wall is fixed for the rest of the press with bales of a given size. Pushing the wrapped bale out of the press chamber is made in the next batch of material. After the bale is pulled out of the press, the rear wall is closed, the next bale is pressed all the way to the rear wall, and the new bale is pressed to the previous bales located in the bale chamber.

Pa figs. 1 shows a device for carrying out the proposed method, side view; in fig. 2 - a device with a rear wall installed inside the press chamber, a longitudinal section; in fig. 3- section A-A in FIG. one; in fig. 4 shows the device at the position of the rear wall after tying the first bale

The device contains a loading chamber 1, a pressing chamber 2, a rear wall 3, which is fixed on the opening mechanism 4, which is mounted on the transverse beam 5, which moves along the guide 6 by means of a hydraulic cylinder 7. The stop 8 is fixed on the guide 6 the press chamber 2 is formed by guides 8 with grooves 10, and the bottom wall by guides 1 with stops 12 and 13. The back wall 3 has lugs 14 in the upper part and lugs 15 in the lower part.

The device works as follows.

The rear wall 3 is installed inside the bale chamber 2 on the bale size (bales) so that the projections 14 are waxed into the grooves 0 of the guides 9, and the projections 15 reach the lugs 12 of the guides 11. These operations are carried out by the hydraulic cylinder 7 and the opening mechanism 4. A compressible mass is fed into the press chamber 2, which is pressed to the back wall 3 1-1 is bound. Next, the rear wall 3 is opened and moved by the hydraulic cylinder 7 to the output end of the pressing chamber 2. In this position, the rear wall 3 in the closed state is held at the top by a transverse beam 5 and the hydraulic cylinder 7, and at the bottom by a projection 15 abutting against the stop 13 of the guides P. Then, a pressed mass is fed into the pressing chamber, which moves the previous bale, which is located on the pressing chamber, up to the stop into the back wall 3. The second bale is formed and tied, the back wall is opened, and With this, the first tied bale is pushed out of the press with the rear wall open. Then the back wall is closed, and then the cycle repeats. The subsequent bales (bales) are pressed to the bales located in the bale chamber, and the pushing of the tied bales is performed as in presses with an open bale chamber.

The proposed method allows bales (bales) of various sizes to be obtained in the same bale chamber, thereby reducing the energy intensity of the bale.
