Description

The invention relates to the field of agricultural machinery, in particular: BUT: STI: To devices for koiprol for the ratio of s; speed 1B1rash, for the working bodies of an agricultural machine, the speed of its recipient CSO movement, and can be controlled For the ratio of the speed of rotation of the reel and the speed of the dwelling d: in the same.

By ociHOBHOiMy auth. St. N ° 221412 is known as a speed controller for controlling the speed ratio, which is used, in particular, in grain harvesters to control the ratio of the reel speed to the speed of the combine and the movement of the combine.

This device has a hollow shaft mounted i3 under the corus cap. Two pairs of sliding blocks are freely mounted on the shaft. The sliding block consists of two DISKS, which are mouths, but are movable relative to each other. The discs are made once by a disk, the tapered disks, which serve as satellites, are fixed on the shaft and rotate in the bearings of the carrier, the latter; kestk | 0 is connected to a gear rack: ka: a gear-rack mechanism. The end of the hollow shaft is connected with a flexible shaft to the p "Eod reel or other working body, and 1Bal shchestris.ni - with a drive running

wheels or track measuring M wheel. Having obtained a cumulative motion, the indicator disc remains on the spot if the turns of the sludge mat correspond to the given mode.

However, in the known device this control is carried out visually, at risk, marked on the index disk, i.e. this device, together with the input codes, must be placed immediately and immediately, by Mbiner. In the event of a violation of the kinematic mode of operation of the reel, the pointing disc will rotate in one direction or another, and, therefore, the co-driver is not known to increase or

reduce reel speed. All this creates certain advantages in the management of the coil.

The purpose of the invention is to improve the quality, quality, speed ratio, the working bodies of the machines.

This goal is ensured by the fact that the known device is equipped with a signaling device made in the form of a J-fiber on a flat loop-shaped spring contact block, hinged on the body of a flat plate and non-stemmed insulated spring-loaded contacts - sensors with an electrical block circuit, and a flat loop-like The spring contact is established with the possibility of interaction with a flat plate, and the last one - with the insulating contacts - sensors.

FIG. Fig. 1 shows (Kinemains's schematic diagram of the instrument for control over the velocity ratio; and Fig. 2 shows section A-L of Fig. 1; Fig. 3 shows the electrical block diagram of operation control of the machine; Fig. 4 - view B of Fig. 1 .

The device for controlling the ratio of speeds contains a hollow shaft. At the gauge (reducer, well-mounted in bearings 2 Housings 3. On the shaft 1 is freely mounted a sliding block of two disks 4 (AND 5. The disk 5 is set to move on step D) | fold: mesh, e, at work the compression spring 6, pressing the disks against each other. On the disk 4 of the disk 4 the gear 7 is fixed, the input is w, and the gear 8 is in engagement. On the right end of the shaft i / installed Blo: to from disks 9 .and 10, made similarly to disks 4 and 5. A proper disk JO is an indication between the D1IS1kam.i and 4 and 5, 9 and 10 are spaced. conical disks 11 and 12, serving as satellites. The distas are fixed on the shaft 13, rotated in the slotted 14 slide carrier 15. The carrier 15 contains telescopic rods 16 and 17, and also plan / 8 and 19, which are rigidly associated with gear rack and 20 and 21 rack and pinion mekapizm-a. Reimi is in tandem with the bristles 22, installed on shaft 23 with a spring-loaded handle 24 fixed on the graduated disks of disk 26. The carrier's length is changed by turning the handle 24. The right end of the shaft / is connected to the flexible shaft with Odom reel or other working body, a pinion shaft 8 - Drive running "or OLES puteizmeritelnym wheels. Shaft 7 and the left block of disks 9 and 10 should be B1 rotated in opposite directions. The length of the dowel is chosen so that the pointer disc 10, receiving a total motion, remains; in place, if o6oipOTbi. The rollers correspond to a given mode. On the disk 10 disk. A limiting disk 2 with a spring loop-shaped contact 27. is pressed. On the axis 28, fixed to the base, there is a movable contact flag 29. But both sides of the movable co-tact flag 29 are at the same distance two different ones are installed. d. mobile; onta.kta - sensor 30 and 31. The common electrical circuit is switched on by a toggle switch 32. An electrical block circuit placed on the control panel will activate two independent sections 33 and 34 with light bulbs 35 and 36 installed in them. Both compartments are closed with different glass panes she,; on which the inscriptions are inscribed: in department 33 - “to increase the turnovers — wind, and in department 34 -“ to reduce the revolutions of the motif.

In the course of work, at the optimum ratio of speeds, the index .disc .10 STO.IT is stationary, the contacts are all open. That indicates compliance with the established relmma of work. In case of speed mismatch, the disk 10 starts to move in one direction or another. When the disk is rotated to the left, an elastic contact. Act 27. Leads the flap; K 29: to a fixed contact - sensor 31, resulting in

the circuit is closed and the signal lamp 36 lights up, which indicates the need to reduce the o6opoTOiB reel. If the com busner did not accept the measures, then DIS.K 10, having made a turn, will repeat

same signal. As the JO disk rotates in the opposite direction, contact 27. Fails the check to the contact 30 to the sensor 30 and closes the second branch of the circuit, resulting in a blinking signal 35 in the section NSh1 34, which indicates the need to increase the reel revolutions. In case the measures are not received, the signals will be repeated. The repetition rate of the signals varies. If the velocity mismatch increases, the signals repeat more often, and vice versa.

The use of the proposed device will allow stabilizing the kinematic mode of operation of the reel and sn;

L1r1ozha for reel m reaper, especially when harvesting stubby bread.
