    专利说明:

    The invention relates to agricultural machinery, in particular to balers, which form rectangular bales of hay, straw and similar materials.
    A baler is known, comprising a bale chamber with a piston reciprocating, and a bale wrapping mechanism with switching devices associated with the toothed measuring wheel 1.
    Under the influence of the press, the pressed mass moves in the channel of the bale chamber and turns the gear wheel, which, when the bale reaches a predetermined length, uses a special rod to turn on the dressing mechanism.
    However, this design cannot be used in balers that form large bales with closed-type chambers, where the hay mass is compressed with the rear door closed and the binding mechanism must be turned on when the bale reaches a given density and not a given length.
    A known baler includes a baler, a loading device, a mechanism for tying bales with a device for switching it on, a pressed chamber with a rear wall having a density sensor of the compacting mass 2.
    The mass of hay or straw, supplied by the pick-up and putter to the bale chamber, is gradually compressed by the oscillating wall. As the gauge plate fills and increases in density, the pressure increases and is transmitted through the oil line to the pressure gauge. According to his testimony, the operator determines the moment of completion of the bale formation and, stopping the tractor, not including the PTO shaft, pulls the belt off. After the dressing is completed, when the needles return to their original position, the rear door automatically opens and the bale is pushed into the field with new incoming batches of material. Then the door is slammed by the action of its weight, and a new bale begins to form in the chamber.
    A disadvantage of the known construction is that it is constantly necessary for the operator to monitor the meter readings while turning back, which leads to rapid fatigue and worsens working conditions. The time spent on stopping and manually turning on the mechanism of the node assembly reduces the productivity of the unit.
    The purpose of the invention is to increase productivity and improve the working conditions of the operator by automating the process of turning on the bale binding mechanism.
    This goal is achieved in that in the baler containing the pick-up.
    a loading device, a mechanism for tying bales with a device for switching it on, a pressing chamber with a rear wall having a density sensor of the pressed mass, an axis with an emphasis for interacting with the tying mechanism is installed on the rear wall, and the sensor is made in the form of a plate pivotally mounted on the rear wall and connected to the axis and the elastic element. Moreover, the emphasis is made by turning the BQ around the axis and provided with a device for fixing it relative to it and indicating the value of the specified density.
    FIG. 1 schematically shows the proposed baler, side view; ya fig. 2 - rear end of the row. camera in a perspective view.
    The baler contains chassis 1, pick-up 2, loading device 3, press chamber 4 with a porsche 5 and periodically opening rear steak 6, having a well-formed density sensor 7, connected to the shaft 8 with a crank 9, fixed on axis 10, Yah which is fixed and the gorge 11, coupled with the elastic element 12, vyployyyym in the form of a spring. The baler also contains a mechanism 13 for tying bales with a device for switching it on, consisting of a chain drive 14, a single turn clutch 15 and a crank 16, connecting rod 17 with a block of 18 needles. Dog 19
    0 one-turn clutch $ 1 in the off position rests on the double-arm lever 20, connecting rod 21 to another two-arm lever 22. On the axis 10, the indicator of the value of the specified density is also set, performed as sector 23 co.
    a scale and an anvil 24 which can be rotated on the axis 10 and fixed by means of a fixture 25.
    On the bale chamber 4 of the hinge, hooks 26 are fixed, holding the trunnions 27 of the wall 6 in the closed position. The wall 6 is rotated by the hinges 28. To return the wall 6 after it is opened to its original position, an elastic element 29 serves, which interacts with the arm 30 fixed on the wall 6. The hook 26 of the rear 31 is pivotally connected with the lever 33 swinging on the axis 32 a roller 34 interacting with an anvil 35 attached to a block of 18 needles.
    The one-turn coupling 15 is mounted on the shaft 36, and the needle block is mounted on the axis 37. The lever 33 has a pin 38, which is inserted into the slots of the rod 31, and the lever 33 is held by a spring 39. The hook 26 is Spring 40 for retaining the rear wall 6 in the closed the position and position of the axis 41. On the press chamber on the side, on the side of the rear wall 6, there is a stop 42 for interacting with the hook 26. The baler operates as follows. In the process of moving the baler along the roll, the crop weight is picked up by the pick-up 2 and fed by the loading device 3 to the bale chamber 4, where it is compressed by the piston 5, reciprocating. As the entire volume of the chamber is filled, the mass reaches the rear wall 6 and begins to exert pressure on the plate of the density sensor 7, which rotates the axis 10 through the rod 8, overcoming the resistance of the elastic force of the elastic element 12. The elastic element 12 is designed in such a way that it starts to stretch only when the pressure on the plate reaches a certain value corresponding to the Required minimum density of the material in the chamber. As the axis 10 rotates, the stop 24, which then acts on the double-arm lever 22, also rotates the chuck 20 through the pullout 21 and the dog 19 of the single-turn clutch 15, i.e., the chain drive 14 is automatically connected to the shaft 36 of the binding mechanism 13. At the same time, the crankshaft 16, fixed on the shaft 36, rotates the needle block 18 relative to the axis 37 through the pull 17. When the needle block 18 rotates, the stop 35, acting on the roller 34, rotates the lever 33, the finger 38 of which moves along the notch in this position torque 31. The lever 33 is rotated until the stop 35 comes out of contact with the roller 34, after which the lever 33 returns to its original position under the action of the spring 39, at which the finger 38 abuts against the end of the groove of the rod 31. Spring 39 is obviously weaker than the spring 40, which holds the hook 26 in the closed position therefore, the lever 33 will remain stationary until the stop 35 approaches the roller 34 (now from the opposite side) upon completion of the binding cycle, i.e. when the needle block is returned. When the stop 35 acts on the roller 34 from the opposite side, the lever 33 uses a finger 38 to move the rod 31, which rotates the hook 26 relative to the axis 41, thus releasing the rear wall trunnion 27 6. 6. The stop 35 again returns from the needle to the initial position. meshing with the roller 34. The back wall 6 under the action of the advancing twisted bale opens, turning on the hinges 28 and compressing the elastic element 29. When the wall 6 is opened, the hook 26 returns to its original position, limited by the stop 42.33 ychag rod 31 also returns to the initial position where the roller 34 again engages the stop 35, i.e. set the initial position of elements of the mechanism. The stop 24 when opening the wall 6 releases the double-arm lever 22, and the spring returns the lever 20 to its original position, in which the dog 19, resting against the lever 20, turns off the clutch 15. The entire process of opening the rear wall occurs in one turn of the crankshaft 16. When dropping the bale holding the back wall 6 in the open position, the elastic element 29 closes it. In this case, the pin 27, slid along the wedge-shaped edge of the hook 26, pushes it, stretching the spring 40, which snaps the hook when the pin is in its original position. When hauling the hook 26 and snapping it, the slide 31 slides on the finger 38, which is still at that moment. Thus, all the mechanisms mentioned above return to their original position, and the whole process of controlling the pressing density of the bale and its dressing takes place automatically. . The reconfiguration of the mechanism of incorporation into the cavity apparatus to obtain bales of a given density is carried out as follows. The fixture 25 is loosened and the stop 24 is rotated on axis 10 relative to sector 23 until the desired density scale division is required, then tightened. Different positions of the anvil 24 allow it to act on the lever 22 at various forces on the sensor 7, i.e. at a higher or lower density of the compressible mass. Thus, the proposed technical solution allows increasing productivity and improving the operator's working conditions by automating the process of activating the bale binding mechanism.
