Description

(54) LIMITER OF VINE-GRINDING MACHINE VIBRATIONS

I

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to the working bodies of harvesting machines.

Limiters of oscillations of a grape harvesting machine are known, including a bar drum connected by means of a vertical axis with a frame hinged on the frame of the machine and connected to the latter with a spring-loaded lever with a tension device. Vibration limiters are installed in front of the grape harvesting machine and in the process of work they limit the zone of propagation of the oscillation wave created by the activators and thereby prevent the crop from being segregated outside the capture zone}.

However, with intensive action of activators on a grape bush, a part of the separated harvest in the form of a year is thrown out of the catch zone, ahead of the machine, into the free space between the rods of the oscillation limiters. In addition, with the free rotation of the drums, the limiting oscillations of the vine, the penetration between the rods, is wound on them, which causes damage to the vines and the drums themselves.

The purpose of the invention is to reduce crop losses and damage to grapes.

This is achieved by the fact that the vibration limiter is provided with reflective plates installed between the axis and the rods of the drum.

FIG. 1 is a diagram of the construction of the vibration limiter; in fig. 2 is a section A-A in FIG. one; in fig. 3 - scheme of operation of the oscillation limiter.

The vibration limiter consists of a frame 1 with a reflective cover 2, a swing frame 3 pivotally connected to the frame, a freely rotatable bar drum 4, a lever 5, a spring 6 and a tension device 7.J

Freely vrashayuasyis drum consists of a central axis 8, the upper and lower rims 9, to which the rods 10 are welded, and reflective plates 11 are installed between the rods and the central axis.

On the harvesting machine installed activators 12.

During the operation of the machine, activators 12 Create a trellis oscillation, as a result of which the harvest is eaten. The drums of 4 oscillation stops perpendicular to the axis of the row limit the zone of propagation of the oscillation wave, and the reflection plates 11 installed between npytKHMH and the central axis of the drum close the catch zone in front of the machine, thereby preventing loss of crop separating directly from the oscillation stops. With free rolling of rod bars || abans of vibration limiters along the shayalers (while the machine is moving), the reflection plates also warn the winding of the shoots of the vine on the rods of the drum and, therefore, damage to the bushes and the vibration limiters themselves. When meeting with tapestry supports, the swing frames with the drums are deflected, passes the support, and then under the action of the springs they return to their original position. The installation between the central axis and the drum rods of the reflective plates ensures the formation of a closed trapping zone and prevents the winding of the windings on the rods of the drums, which reduces crop losses and damage to the grape bushes. Claims of the grape harvesting machine, including a bar drum, connected by means of a vertically positioned axis to a frame hinged on the machine frame and connected to the latter by means of a spring-loaded lever with a tensioning device, characterized in that in order to reduce crop losses and damages vines, it is equipped with reflective plates installed between the axis and the rods of the drum.
