The invention relates to agricultural machinery and can be used in presses for pressing large bales, mainly from haymaking materials.

A press for haymaking materials press containing a press chamber, a piston connected to a connecting rod of a crank connecting rod mechanism, and a flywheel 1 are izweiten.

A disadvantage of the known press is that there are difficulties in creating presses, pressing, haymaking material into large bales of high density mainly due to the fact that the prepressing and pressing operations of the material in it are carried out by moving the piston to one and the same value using the crank mechanism. Therefore, the press must have a large pressing force, the path and the frequency of the piston strokes. The fulfillment of these conditions leads to an increase in the size, mass and energy intensity of the press.

Repeated force action of the piston on the material in the process of its pressing and pressing leads to a decrease in the quality of pressing when forming large bales.

The closest in technical essence to the present invention is a press for pressing hay materials, which includes a crank but-crank mechanism, the crank of which is designed as a hydrocylic rod, connected with noptiHeM 2.

The disadvantage of it is that the repeated impact of the piston on the material in the process of its pressing and pressing leads to a decrease in the quality of pressing during the formation of large bales.

The purpose of the invention is to improve the quality of pressing in the formation of large bales.

This goal is achieved by the fact that a press for pressing hay and straw materials, including a crank mechanism, the crank which is made in the form of a hydraulic cylinder connected to a piston, is provided with a coupling mounted on the crankshaft shaft and an associated pawl for stopping the crank mechanism and activating the hydraulic cylinder with the extreme forward position of the piston.

FIG. 1 shows a diagram of the proposed press in the process of prepressing, side view; in fig. 2 - the same when pressing.

The press for pressing hay materials consists of a pressing chamber 1 with a loading window 2, 3 and a crank-crank mechanism 4 with a crank 5 and a connecting rod 6, made in the form of a hydraulic cylinder. A clutch 8 is mounted on the shaft 7 of the crank mechanism to be turned on with a lug 9 and a pawl 10, to stop the crank mechanism 4 and to turn on the hydraulic cylinder at the extreme. front piston position 3.

The press works as follows

The material is fed into the press chamber 1 through the loading-window 2. The dog 10 during filling of the press chamber 1 with the material is in the raised position and the clutch 8 transfers the torque to the crank 5 of the crank mechanism 4, which moves the piston 3 from the rearmost I the frontmost II, through the intermediate 11 position and back, i.e. tells the piston to return a reciprocating motion in the receiving chamber 1. During this movement, the piston 3 continuously displaces the feed window 2 fed through the press to the press. joint chamber 1, simultaneously pressing it in. At the same time the hydraulic cylinder works as a rigid rod.

When filling the volume of the press chamber 1 with the compressed material, which is established either visually by the operator or with the help of known technical solutions, for example, a measuring wheel or a spring-loaded rear wall, the dog 10 is lowered by the operator (the tractor operator using a hand connected to the dog 10 th or hydraulically {not shown in the diagrams), and stops the clutch, approaching the protrusion 9 is always in the same place, corresponding to the extreme front position of the crank 5 and the connecting rod b, and turns off the clutch 8.

After stopping the crank mechanism in the extreme forward position III of the piston 3, the operator (or tractor operator) uses the tractor's hydraulic distributor i to turn the hydraulic cylinder on a working stroke to press the material to the required density, moving the piston 3 from position III to position 1U. The compressed material is wrapped in a bale (not shown in the inlet apparatus).

Thus, the material is pressed by a single force action of the piston 3.

After the compressed material is wrapped, the hydraulic cylinder is turned on by the operator or the tractor driver with the help of the tractor's hydraulic distributor on the return stroke of the rod and the piston 3 returns from position IV to position III. Yes, the tripping dog 10 rises

upwards by the operator or the tractor operator with the help of a handle connected to a 10t dog or a hydraulic drive and releases the protrusion 9, including the clutch 8 and the piston 3 again begins to reciprocate, shifting through

A loading window 2 is inserted into the bale chamber 1, and the whole process is repeated,

In a way, the proposed press i allows ;; It does not improve the quality of pressing in the formation of large bales.
