Description

The invention relates to mechanical engineering and is intended for the treatment of pests of a threshing drum of grain harvesting machines in an automatic line.

The aim of the invention is to increase the productivity of the process by simultaneously supplying several parts to one technological equipment.

Figure 1. Shows a longitudinal section aa; figure 2 is a section bB (top view); Fig. 3 is a ratchet locking mechanism.

The transport device comprises a multi-tray table 1, which is common to the loading device. In each tray 2, feed rollers 3 are mounted on a common shaft 4, which are rotated by an electric motor 5 through a reducer 6. The spring-loaded rollers 7 are independent of other rollers and perform three functions: the ability to receive a whip strip from a loading device and press it against feed rollers 3 in order to create friction forces for movement and to give a signal after spending the strip to subsequent nodes. .

The locking device consists of two interacting nodes: the probe mechanism 8 and the feeding mechanism 9. The clamping levers 10 are connected to the rod 11 and are driven from the cylinder 12. The signaling spring stops 13 are freely mounted on the axis in the levers 14, which in turn are attached to the shaft 15. Against each signaling stop 13, a fixed induction sensor 16. These stops come into operation once at the beginning of the reception of the strip through the lever 17 from the cylinder 18. The ratchet mechanism 19 with the control cams 20 is driven e of lock 21 mounted on the carriage of the cutting machine, the pawl 22.

The device operates as follows.

As soon as the feed rollers 3 are released from the workpieces, the spring-loaded rollers 7 are lowered and the stops 23 attached to the other end of the lever press the limit switches 24, which command the cylinder 18 through the electric hole 25 to install the levers 14 together with the signaling stops 13 in a horizontal position and at the same time with a delay, give the command to the sliders of the loading device to feed the strips into the feed rollers 3 and 7. Moreover, the commands from the limit switch 24 will be executed provided that the cutting zone is released automaton

from the cut pieces, So, the working area is freed and the commands are executed.

When the strips are fed into the feed rollers 3 and 7, the sliders of the loading device

give the command to the rollers to move: the strips, As soon as all the strips reach the signaling stops 13, they will contact the induction sensors, which will give a signal to stop the supply of roles 3 through the gearbox b from the electric motor 5 and with a delay will give the command to the cylinder 18 through the electric 25 to lower the signaling stops 13 to the initial position (Fig. 1) and also with a delay of yes5 give a signal to the limit switch 26 for executing commands to the probe mechanism 8 and the feed mechanism 9, which were interrupted by the limit switch 24 .

After the base reef has been set to its predetermined position during the interaction of the probe 8 with the feeding mechanism 9 of the fixing device, it gives a command via the induction sensor 32 to the cylinder 12 through the electric pickup 27 to clamp the strips to the table. At the end of the clamp, the stop 28 presses the end switch 29, which will command the cutting carriage to trim the end face. After the cuts, the carriage returns. And with

0 dogs 22 through a ratchet gear leads the cam 20 to the end switch 30, from the contact of which the locking device is turned off and the strips are compressed by the cylinder 12. After

5 to release, the induction sensor 31 instructs the feed rollers 3 and 7 to feed the scouring strips to subsequent signaling stops, if permission is given.
