Description

FIG. 2

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to a device for preventing the breakage of forage harvesting machines.

The purpose of the invention is to increase the reliability in the work.

Figure 1 shows schematically the proposed foreign object controller; figure 2 - section aa in Fig, 1; fig.Z - electrical circuit.

The foreign object controller consists of a drum 2 installed on the frame 1, equipped with needles 3, and an impurity sensor made in the form of a contact drum 4 placed inside the main drum 2, and a con-. . clock heads 5 mounted on the ends of the needles 3 using dielectric washers 6. Needles 3 are installed inside the main drum 2 with the possibility of radial movement relative to the outer surface of the drum 2 by means of concave springs 7. The contact heads 5 are functionally connected to the contactors 8 by a power supply 9 , relay 10, signal dumps II and ringing 12, engine start and power device 13 (not shown).

The controller of foreign objects pa-jQ of the drum, and heads mounted on

bots as follows.

The drum 2 moves over the controlled forage mass, while the needles 3 freely penetrate into the layer of needle crowns by means of dielectric washers, the needles being installed .- .. inside the main drum with the possibility of radial movement of the contact head 5 on them 5 or converge to contact the drum 4, the electrical circuit is closed, the warning lamp 11 is turned on and the bell 1-2 is turned off, the engine is turned off, the unit is stopped and cannot be started before the object is removed

to work

The use of the proposed device improves the reliability of the unit, eliminates its breakage due to the ingress of foreign objects, and also allows you to smoothly adjust the force required to operate the sensors when changing the device to control the forage with a different rheology.
