Abstract

The invention relates to mechanisms for the processing of agricultural products and can be used in packaging machines in which the feeding to the weighing device is carried out using vibrating channels. The aim of the invention is to simplify the design and usability. When the shaft 5 with cams 6 rotates, the number of which corresponds to the number of trays 1, the oscillatory motion in the horizontal plane is transmitted through the rollers to the trays 1. If it is necessary to turn off any of the trays 1, a traction electromagnet is activated, the core of which is connected to a lever whose end acts on stop tray 1. At the same time, the lever closes the tray flap through the drum. The oscillation amplitude of the tray 1 is adjusted by axial movement of the shaft 5 relative to the frame using the flywheel 13. This moves the contact point of the cam 6 with the roller, changes the eccentricity and, accordingly, the movement of the tray 1. All the trays receive movement from one electric motor. 1 hp f-ly, 3 ill. to

FIG. 2

The invention relates to mechanisms for the processing of agricultural products and can be used in packaging machines in which the feeding to the weighing device is carried out using vibrating channels.

The purpose of the invention is to simplify the design and usability.

FIG. 1 shows a vibrating feeder, side view; in fig. 2 - drive shaft axis, cut; in fig. 3 - cam, cut.

The vibrating feeder contains trays 1, which with the help of lamellar springs 2 are attached to an UNDERBASE base 3. The vibrating filler has an electric motor 4, a drive device containing a drive shaft 5 located perpendicularly to them, with a drive shaft 5 installed on it under each tray .m 1 by cams 6 and rollers 7 fixed on each m. of tray 1 with the possibility of interaction with cams 6. The feeder is equipped with a mechanism for disconnecting trays 1 from the drive device, including autonomous electromagnets 8 each of which They are connected to the lever 9, the free end of which is installed with the possibility of contact with the supports 10 fixed on the trays I. To the end of each lever 9 there is attached a ha 11 connected to the hinge 12. Each cam 6 in cross section with a longitudinal plane is a trapezium the sides of which serve as the working surface of the cam. The feeder contains a flywheel 13 for adjusting the oscillation amplitude of the trays 1.

Vibrating feeder works as follows.

The motor 4 by means of a belt transmission causes the shaft 5 to rotate by cams 6, the number of which corresponds to the number of trays 1. When rotating, the cams 6 through the rollers 7 set the tray to oscillate in a horizontal plane.

Tray 1 is pressed to cam 6 by plate springs 2. If any of the

Trays 1 or all together includes a traction electromagnet 8, the core of which is connected to the lever 9, which acts on the stop 10 of the tray, 1, thereby removing the tray 1 from the cam 6. At the same time, the lever 9 closes the shutter 12 of the tray through t 11.

The oscillation amplitude adjustment of the tray 1 is carried out by axial movement of the shaft 5 relative to the base by means of the flywheel 13. This moves the contact point of the cam 6 with the roller 7, changes the eccentric system and, accordingly, the movement of the tray 1.

The use of the proposed device of the vibrating feeder will significantly simplify the design, since all the trays receive movement from one electric motor, preserve the autonomy of their movement, increase the durability of the nodes, and provide ease of maintenance.

Claims (2)
