Abstract

Изобретение относитс к сельскому хоз йству, в частности к приводным механизмам режущих аппаратов жаток или косилок. Цель изобретени - упрощение конструкции. Механизм привода содержит корпус 1, в котором установлен кривошипный вал 3 с шатунами 5, посредством которых привод тс в колебательное движение поводки 6, на одних концах которых закреплены дугообразные ножи 7, а другие концы установлены на общей оси 8 вращени . Один из ножей 7 закреплен на своем поводке 6 цанговым зажимом 9. 1 з.п. ф-лы, 2 ил.FIELD OF THE INVENTION The invention relates to agriculture, in particular to the drive mechanisms of the cutting apparatus of the headers or mowers. The purpose of the invention is to simplify the design. The drive mechanism includes a housing 1 in which a crank shaft 3 with rods 5 is installed, by means of which the drivers 6 are driven into oscillatory motion, at one end of which arc-shaped knives 7 are mounted, and the other ends are mounted on a common axis of rotation 8. One of the knives 7 is fixed on its leash with a 6-collet clamp 9. 1 cp f-ly, 2 ill.

,Изобретение относитс к сепъскому хоз йству, в частности к приводным механизмам режут их аппаратов жаток или косщюк., The invention relates to a septic enterprise, in particular to drive mechanisms, they cut their heads or skins.

Цель изобретени - упрощение конструкции .The purpose of the invention is to simplify the design.

На фиг.1 показан механизм, общий вид, план; на фиг.2 - разрез А-А на фиг.1.Figure 1 shows the mechanism, general view, plan; figure 2 - section aa in figure 1.

Механизм привода содержит корпус 1, в котором на подшипниках 2 уста- новлен кривошипный вал 3. На криво- : шипах вала установлены подшипники 4 ;и шатуны 5, шарнирно св занные с поводками 6 ножей 7. Концы поводков 6 св заны общей осью вращени 8. Один из ножей 7 соединен с поводком 6 цангой 9.The drive mechanism includes a housing 1, in which crankshaft 3 is mounted on bearings 2. On curvature: shaft studs, bearings 4 are installed; and connecting rods 5 pivotally connected to the drivers of 6 knives 7. The ends of the leads 6 are connected by a common axis of rotation 8 . One of the knives 7 is connected to the leash 6 by collet 9.

Механизм привода режу1цего аппарата работает следующим образом.The drive mechanism of the cutting apparatus operates as follows.

При подготовке к работе ножи 7 с помощью цанги 9 устанавливаютс па- ;раллельно друг другу. При работе вращение кривошипного вала 3 через подшипники 4 приводит в движение шатуны 5, которые в свою очередь за15953784In preparation for operation, the knives 7 with collet 9 are installed parallel to each other. When working rotation of the crank shaft 3 through the bearings 4 sets in motion the connecting rods 5, which in turn 15953784

Claims

1. A two-knife cutting machine drive mechanism comprising a housing with a crank shaft mounted therein, connected by connecting rods with knives' leads, the leads being fixed on a common axis of rotation; and the axis of rotation of the leads, and the connecting rods are made in the form of eccentric washers pivotally mounted on the crank shaft and fixed

in the body of the leads, and the knives are made in the form of an arc of a circle, whose center coincides with the axis of rotation of the leads, and are rigidly fixed on these leads

2. The mechanism of pop, 1, distinguishes u and with the fact that one of the knives is fixed on its leash by means of a collet clamp.

F. formula of invention

in the body of the leads, and the knives are made in the form of an arc of a circle, whose center coincides with the axis of rotation of the leads, and are rigidly fixed on these leads.
