(54) ЯМОКОПАТЕЛЬ(54) MOBILE

1one

Изобретение относитс к сельскохоз йственному машиностроению, в частности к устройствам дл рыть м.The invention relates to agricultural machinery, in particular to devices for digging m.

Известен мокопатель, включающий бур с редуктором, продольные т ги навески и центральную т гу, гидроцилиндр и привод 1.A well-known scooper includes a drill with a gearbox, longitudinal links of a hinge and a central tractor, a hydraulic cylinder, and a drive 1.

Недостатком известного мокопател вл етс то, что при его работе, за счет внедрени шнека в стенки мы, происходит интенсивное погружение бура, в результате чего происходит буксование предохранительной муфты, а следовательно, уменьшение производительности мокопател .A disadvantage of the known scooter is that during its operation, due to the insertion of the screw into the walls of the we, an intensive immersion of the drill occurs, as a result of which the safety clutch slips and, therefore, the performance of the scootel decreases.

Известен также мокопатель, содержащий бур, соединенный с имеющим горизонтальные кронштейны редуктором, на котором шарнирно закреплена навески 2.Also known mokopatel containing a drill connected to a horizontal bracket having a gearbox, on which the hinge 2 is hinged.

Недостатками известного мокопател вл ютс его сложна конструкци и невозможность обеспечени строго вертикального заглублени бура. В результате этого значительна часть грунта срезаетс витками шнека, а не лемехами, что приводит к увеличению объема работ и энергоемкости процесса .The disadvantages of the known scooter are its complex structure and the impossibility of ensuring a strictly vertical penetration of the drill. As a result, a significant part of the soil is cut off by the turns of the screw, and not by the plowshares, which leads to an increase in the volume of work and the energy intensity of the process.

Целью изобретени вл етс обеспечение вертикального заглублени мокопател .The aim of the invention is to provide a vertical burial of the scooppel.

Эта цель достигаетс тем, что в мокопателе рамка навески снабжена амортизаторами , а редуктор - установленным свер5 ху него Г-образным кронштейном, на котором смонтирована одна из т г рамки навески , при этом оси штоков амортизаторов и кронштейны установлены в шарнирах эксцентрично относительно осей их вращени .This goal is achieved by the fact that the frame of the linkage is provided with shock absorbers in the scooter, and the gearbox is mounted with an L-shaped swivel bracket on which one of the linkage hr frames is mounted, while the axes of the shock absorbers and the brackets are mounted in the hinges eccentric about their axes .

Claims

Q In FIG. 1 shows a scraper, general view; in fig. 2 - kinematic linkage diagram; in fig. 3 is a view A of FIG. 1. The drive machine contains a drill 1 with a gearbox 2, which is connected to a drive (not shown). On the top of the gearbox, G-ob15 is fixed with a different bracket 3, and on the side - horizontal brackets 4. Brackets 3 and 4 are mounted in the hinges 5 eccentrically relative to the axes 6 of their rotation. The frame of the mokopatel consists of the upper 7 and lower 8 tons of g, which are connected to the arms of 9 hinges 5. In addition, the hinge contains shock absorbers 10, the axes of the rods 11 which are mounted in the hinges 5 are eccentric relative to the axes of their rotation. The hole digger is hinged by means of a frame hinged on tractor 12 at points 13-16. The scooper is raised and lowered by means of a remote cylinder 17. The hole digger works as follows. Having installed the drill 1 on the ground and giving it rotation, the hydraulic cylinder 17 begins to deepen it. At the same time, before the beginning of the deepening, the longitudinal axes of the shock absorbers 10 pass over the axes 6 of the hinges 5 along the chord, and the springs of the shock absorbers are fully released. From the moment of deepening, the longitudinal rods 8 begin to rotate around the hinge point 15, while the hinges 5 begin to rotate clockwise in the holders 9 and thereby compensate for the displacement of the drill relative to the vertical axis. When we reach the horizontal line passing through point 15, and digging up half the depth we, the lower rods 8 begin to deviate downwards. and the hinges 5 begin to rotate counterclockwise and also compensate for the displacement of the drill from the vertical axis. Thus, during the digging process, the drill 1 is penetrated perpendicularly. Drilling is done in the same way, but in reverse order. The use of the invention makes it possible to reduce the amount of excavated soil as well as reduce the energy consumed by the auger, as a result of which the processing of denser soils becomes possible. Claims A hole containing a drill connected to a horizontal gearbox with a hinged frame attached to it, characterized in that, in order to ensure vertical penetration, the hinge frame is provided with shock absorbers and the gearbox is mounted on top of it by a L-shaped hanger that One of the hinges of the hinge frame is mounted, while the axes of the shock absorber rods and brackets are mounted eccentrically in the hinges relative to their axes of rotation.
