Изобретение относитс к землеройным машинам, а именно к траншейным машинам дл выполнени щелевого дренажа и узкотраншейных водовыпусков из каршовых каналов на пол х производства фрезерного торфа. The invention relates to earthmoving machines, namely, trenching machines for performing slotted drainage and narrow trench outflows from Karsh channels on the fields of milled peat production.

Известна машина дл закладки трубчатого дренажа, включающа базовое шасси, рабочий орган в виде шнекфрезы и его привод tl.A known machine for laying a tubular drainage, comprising a base chassis, a working tool in the form of augers and its drive tl.

Наиболее близким, техническим решением вл етс рабочее оборудование землеройной машины, включающее рану базовой машины, рабочий орган с редуктором, который соединен с валом отбора мощности базовой машины посредством двухшарнирной карданной передачи 2.The closest technical solution is the working equipment of the earth-moving machine, which includes the wound of the base machine, the working body with a gearbox, which is connected to the power take-off shaft of the base machine by means of a double-joint cardan transmission 2.

Недостатком вл етс то, что при изменении глубины копани измен етс угол наклона рабочего органа и нарушаетс равенство углов между . смежными валами карданной.передачи, что нарушает частоту вращени ведомого вала, а следовательно, снижает надежность работы всего привода рабочего органа.The disadvantage is that when the depth of digging is changed, the angle of inclination of the working member changes and the equality of the angles between the two is violated. adjacent shafts of the cardan drive, which violates the frequency of rotation of the driven shaft, and therefore reduces the reliability of the entire drive of the working body.

Цель изобретени - повышение надежности привода при изменении глубины копани .The purpose of the invention is to increase the reliability of the drive when changing the depth of digging.

Достигаетс цель тем, что в землеройном рабочем оборудовании дл рыть щелей, включающем землеройный рабочий орган с редуктором, соединен10 ный с рамой базового т гача шарниром поворота и гидроцилиндром, и двухшарнирную карданную передачу, ведущий вал которой соединен с приводом базового т гача, а ведомый - с редук15 тором рабочего органа, шарнир пово рота расположен в точке пересечени осей ведущего и ведомого валов карданной передачи и на равном рассто нии от ее шарниров.The goal is achieved by the fact that in the earthmoving work equipment for digging gaps, including an earth-moving working body with a gearbox, connected to the base frame of the steering shaft by a hinge and hydraulic cylinder, and a two-joint cardan drive, the drive shaft of which is connected to the drive of the base tractor, and the driven shaft with the gear of the working body, the hinge of rotation is located at the point of intersection of the axes of the drive and driven shafts of the cardan gear and at an equal distance from its hinges.

Claims

Figure 1 shows earth-moving equipment, side view; in Fig.2, view A in Fig.1; FIG. 3 is a kinematic diagram of the drive of the working member; in fig. - section bb in figure 1; Fig.5 section bb In Fig.2. The earthmoving equipment is mounted on the base plate 1 with the frame 2, on which the rotary in the vertical plane pivotally mounted and controlled by the hydraulic cylinder 3, the working body is made, for example, in the form of the screw-milling cutter 4, of the double-hinged cardan drive 5 with the driving 6 and the slave 7 shafts, an internal fork 8 and a splined shaft 9 of the closing device 10. The working body rotates from the gearbox 1 1 with the hinge 12 rotations. Behind the screw cutter on the gearbox housing 11 there is fixed a casing in the form of a beam 13 of variable length T-section Two-joint cardan transmission is installed so that at equal distances from the hinge centers of the intersection of the axes of the master 6, and the driven 7 shafts is located on the geometrical axis 12 of rotation of the working body 4. Such an arrangement of the cardan gear ensures the equality of the angles (Fig. 3) at different depths of the working body. The work of the earthmoving equipment is as follows. With a raised working organ / | k base machine T enters the working passage, the rotating working body is moved to the working position and simultaneously the working stroke is activated. When the machine is in operation, the drain holes are torn off and the upper part of it is closed by the apparatus 10. The use of the invention improves the reliability of the drive of the working body at various positions. Claims for earthmoving equipment for digging a shell. including a digging tool with a gearbox, connected to the base frame, a swivel hinge and hydraulic cylinder, and a two-hinged cardan gear, the drive shaft of which is connected to the drive of the base gear hatching machine, the gearbox of the working body, characterized in that increase of reliability when changing the depth of digging, the hinge of rotation is located at the point of intersection of the axes of the drive and driven shafts of the cardan gear and at equal distance from its hinges.
