    A sensor for use in the automatic control of an agricultural machine wherein a change in distance from a crop boundary or row of plants, is transmitted as a positional change to the solenoid plunger of an inductive transmitter comprises a housing (1) connectible to an agricultural machine and a rotatably journalled spring-loaded pin (2) with a crank pin (3), which is mounted at the front end of the pin (2) and which bears against a collar (13) of a spring-loaded, displaceable sleeve connected to a push rod (11) of the plunger. Mounted on the pin (2) opposite to the crank pin (3) is a lever arm (5) with a rotatably journalled and spring-loaded pin (6), to which are attached a feeler element (7), which is movable along a crop boundary or row of plants, and a stop (25). A stop (26) co-operable with the stop (25) is mounted on the lever arm (5) and a peg (14) projects from the pin (2) and into a recess of the housing (1). When a crop boundary 28 is sensed by movement of arm 7, this movement is transmitted to pin 2 as a rotational movement and as a result plunger 9 of the transmitter 10 is displaced by pin 3. <IMAGE>

    2. The device according to claim 1, characterized in that a cylindrical spring is installed in the recess of the body, fixed at one end in the hole in the body and the other in the hole of the centering washer, which is rigidly connected to the axis and the lever.
    3. The device according to claim 1, characterized in that under the cap, which is rigidly connected to the trunnion, a cylindrical spring is installed, previously wound up in the direction opposite to the direction of winding the spring of the housing, with the ends thereof
    strengthened respectively in the lever and the cap, which is provided with a stop.
    4. The device according to claim 1, characterized in that the probe of the sensor, made in the form of a straight or curved rod, is fixed in the transverse hole of the trunnion by means of a locking screw installed in the axial threaded hole.
    5. The device according to claim 4, characterized in that the transverse hole in the pin for mounting the sensor probe is figured - its profile is predominantly four or six-sided.
    The invention relates to agricultural machinery, namely, devices that provide automatic driving of self-propelled agricultural harvesting machines, mainly for driving corn combine harvesters on a number of plants or planting borders.
    A device is known that includes probing elements located on rotary housings around stationary axles that actuate sensors (GDR Patent No. 113684, class A 01 B 69/04).
    However, the known device is characterized by insufficient moisture resistance, large dimensions, a large moment of inertia of the mass of the rotating housing, and an unsuccessful mounting system on the harvesting machine.
    The purpose of the invention is to ensure the moisture resistance of the sensor due to reliable sealing of the point of connection of the probe to the sensor and the reduction of the dimensions of the device.
    The goal is achieved by installing a bearing in the housing, mounted on an agricultural machine, and an axis provided with a cylindrical spring, on the inner end of which there is a crank pin abutting the shoulder of a spring-loaded movable sleeve connected to the stem, while securing on the outer end of the shaft a lever with a trunnion mounted on it in a bearing, fitted with a spring and a probe probe, interacting with the stand of the plantations or a number of plants, with the stop of the trunnion cap mounted so that it can work together with an emphasis on the lever, and the pin of the axis moves along the groove in the housing.
    A coil spring is installed in the undercut of the body, fixed at one end in the hole in the case, and the other in the hole of the centering washer, which is rigidly connected to the shaft and lever.
    A cylindrical spring is installed under the cap rigidly connected to the trunnion, while the spring is previously inserted in the direction opposite to the winding of the spring of the body, and its ends are fixed in the lever and the cap, respectively, which is provided with a stop.
    The probe stylus, made in the form of a straight or curved rod, is reinforced
    in the transverse hole of the trunnion with a locking screw installed in the axial threaded hole.
    The transverse hole in the axle for mounting the sensor probe is figured - its profile is predominantly four or
    hexagonal.
    FIG. 1 shows the housing of the probing device, a longitudinal section; in fig. 2 - the device, a general view from above; in fig. 3 is a section A-A in FIG. 2
    In case 1, mounted on an agricultural machine, axis 2 is movably fixed by bearing 2 with crank pin 4 on the inner end, which rests on flange 5 of spring-loaded sleeve 6. A rod is mounted on sleeve 6
    7 with a core 8 of sensor 9 at the end. The axis 3 is provided with a pin 10, the free end of which moves along the groove 11, which limits its movement, the centering pawl 12 and the lever 13 are fixed on the outer end of the axis 3, and in the recess 14
    a cylindrical spring 15, the fixed end 16 of which is located in the Hole 17 of the housing 1, and the movable 18 in the hole 19 of the centering washer 12. At the end of the lever 13 by means of the bearing 20, the housing 21 is movably mounted pin 22, on
    the cap 23 with the stop 24 is fixed. Between the case 21 and the cap 23 there is placed a cylindrical spring connecting them 25, and in the figured hole of the trunnion 22 a probe 26 is fastened with a screw 26. 23 when the probe 27 is in contact with the plant stalks 29.
    The device works as follows.
    The probing of a row of plant stems 29 or planting boundaries is carried out by probe, 27, while the probing force is transmitted by means of cap 23, stops 24 and 28 to lever 13, which, moving, rotates axis 3 with Krivostym finger 4. Cruel pin 4 rests on collar 5 spring b bushings and displacement -1
    ABOUT
    em it for some distance. This also moves the core 8 of the sensor 9, which is connected to the spring-loaded sleeve 6 by means of a rod 7.
    The proposed probing device provides full waterproofness of the sensor and allows to significantly reduce its dimensions, while simplifying the mounting of the device on the harvesting machine and the maintenance process.
    It is recognized as the invention of the results of the examination carried out by the Office for the Invention of the German Democratic Republic.
