how used farm straw pressing machine (feed)

Straw pressing machines (feed)

This type of machinery takes hay or green feed after drying from the surface of the soil, and in the form of rectangular or circular bales and tie it to the thread.

There are two kinds of feed presses:

Frequency Feeding Machine

Circular Feeding Machine

First: Frequency Feeding Machine:

This machine compresses the feed in rectangular bales 90 cm long and 40 cm width, making it easy to process and transport, which consists of:

1 - Pickup device:

It consists of spring skewers that rotate in the direction of reverse rotation of the earth wheel (up and down). The picker picks up the feed crop from the surface of the earth and inserts it into the machine.

The lifting and lowering of the picker can be carried out to suit the nature of the soil so that the skewers do not collide with the soil surface or the obstacles present in it.

On the picker is a network of skewers that prevent the scattering of straw by wind when caught.

2. Feeding Device:

The feeder may move the straw and insert it into the press room after it has been raised to the machine by the catcher. The feeder may be a helical drum that moves the hay near the cupboard to meet a special straw that enters the straw into the cupboard. The clipper pulls the straw with it while the piston is back and when the piston moves forward, the thorns are outside the press room. The spiral cylinder can be replaced by two sets of first flakes that deliver the crop near the piston chamber to take the second set of throws by pulling it into the chamber.

3 - the pressing device

Is a piston that moves in the compression chamber (forward and backward) due to its connection to an elbow shaft that draws movement from the back shaft. There is a knife on the piston wall that works with another fixed knife located at the back of the feeding chamber. Inside the cable room for the outside.

The piston during an advance forward feeds the feed inside the cupboard. In the case of the piston back, the clipped straw falls back and falls inside the cupboard. In order to overcome this problem, many methods have been used to fix the straw inside the piston chamber when the piston is back. :

* Make the inner wall of the cupboard room is grainy and curvy and has protrusions that prevent the feed from falling back and falling while the piston is back.

* Put the crumbs on the bottom and ceiling of the cupboard room and these jaws are equipped with a swiss that will always allow them to emerge in the clipping chamber. When the piston is pressed, it presses the jaws, which leads to entering the bottom and ceiling of the clasp chamber. When the piston returns to the back, I ordered the feed and did not allow it to fall back and fall inside the room.

The feeder continues to feed and pull the crop into the piston chamber by pressing it until the feed bale exits from the outside stream at the end of the cupboard.

It is possible to control the height and width of straw bales, where there are two arms connected to the roof of the course, and through these arms can raise and reduce the outer course of the straw room, and thus control the height of straw bales, the lower the ceiling of the stream, this will reduce the height Bale straw.

The width of the bala can be controlled by pressing on both sides of the tube chamber. The lower the width of the stream, the lower the width of the straw bala.

There is a wheel called the star wheel in the roof of the outer tube of the chamber and its teeth are touched by the upper surface of the bala while pushing the piston to the straw in the chamber of the pack. This wheel is used to determine the length of the bala.

4. The contract device (shuttle):

After the straw bales are reached and reached to the specified length, which is set and determined by the star wheel, the contract device attaches the thread to a nylon, flax or sisal, and then the piston presses another ballet to push the bales that have been tied to the ground.

The process of linking the bala in three stages:

Stage 1: When the piston is ready to work, the tip of the rope outside the pulley is connected to the needle and the second end is connected to the contract device.

Stage 2: When the piston presses the straw, the hay comes out of the chamber of the clipper, carrying the cord to surround the hay bales from top to bottom and back.

Third stage: When you reach the straw machine to the specified length, the needles rise up with the pull of the end of the thread to be delivered to the contract device, which is the process of binding Bala.

Second: Circular Feeding Machine

This machine is composed of the same parts of the feed feed machine, but the press room consists of two tracks, one upper and the other lower, thus the final form of bales in the form of a cylinder.

As the straw enters the chamber, the lower walk moves and wraps around the crop inside the machine and the upper walk is equipped with a hexagon or a hydraulic cylinder that enables it to press the straw in the chamber of the capsule and the upper walkway as a result of friction and pressure on the bala. The size of the bala presses the upper wheel. When the bales reach the required size (machine controlled), they are connected to the thread that is fed with the crop inside the machine. After the binding process, the back gate of the machine is opened to push the bales outwards.
