(54) ПОДКАПЫВАЮЩЕЕ УСТРОЙСТВО(54) PACKING DEVICE

II

Изобретение относитс к сельскохоз йственному машиностроению, а именно к выкапывающим устройствам, и может найти применение в корнеклубнеуборочных и других маишнах, включаклдих операции подрезани почвенного пласта и его сепарации.The invention relates to agricultural machinery, in particular to digging devices, and can be used in root-harvesting and other machines, including the operation of cutting the soil layer and its separation.

Известно подкапывающее устройство, включающее лемех, установленный на подвесках и шарнирно св занный с кривошипно-коромысловым механизмом привода l .A digging device is known, which includes a plowshare mounted on hangers and pivotally connected to a crank-beam drive mechanism l.

Однако известное устройство характеризуетс недостаточными степенью крошени почвенного пласта и скоростью его перемещени .However, the known device is characterized by an insufficient degree of crumbling of the soil layer and the speed of its movement.

Цель изобретени - интенсификаци процесса крошени почвенного пласта .The purpose of the invention is to intensify the crushing process of the soil layer.

. Указанна цель достигаетс тем, что шарнир креплени лемеха к механизму привода размещен на продолжении шатуна со стороны коромысла. При этом Коромысло св зано с шатуном noq .редством ползуна и выполнено регулирую |емь1м по длине.. This goal is achieved by the fact that the hinge of fastening the plowshare to the drive mechanism is located on the extension of the connecting rod from the rocker side. In this case, the Yoke is connected with the connecting rod noq. By means of a slider and is made adjustable in length.

На чертеже схематически изображено предлагаемое подкапьшающее устройство .The drawing schematically shows the proposed undercutter.

Устройство включает лемех 1, установленный на подвесках 2 и св зан- ный через шарнир 3 с кривошипно-коромысловым механизмом привода, состо щим , в свою очередь, из кривошипа 4, The device includes a plowshare 1 mounted on hangers 2 and connected via a hinge 3 to a crank-beam drive mechanism, which in turn consists of a crank 4,

Ш шатуна 5 и регулируемого по длине коромысла 6. При этом последнее св зано с шатуном 5 посредством ползуна 7, а шарнирЗ креплени лемеха I к механизму привода размещен на продолIS жении шатуна 5 за коромысло 6.The connecting rod 5 and the adjustable rocker arm 6. The latter is connected with the connecting rod 5 by means of the slide 7, and the hinge of the fastening shares I to the drive mechanism is located at the extension of the connecting rod 5 by the rocker 6.

Устройство работает следующим образом .The device works as follows.

Claims

Fluctuating plowshare I cuts the soil layer and makes it move backwards due to periodic tossing. Since different points of the plowshare do not have the same trajectory of movement, the dragging of the formation takes place and its crumbling is intensive. The speed of soil movement is controlled by re-securing the slide 7 on the connecting rod 5, and the inclination angle of the plowshare 1 is changed by changing the length of the rocker arm 6. The proposed device allows to intensify the process of impacting the working surface of plowshare 1 on the bedding layer and increase its speed at the optimum rotation frequency and radius crank 4. Invention formula 1. An undermining device, including a plowshare, mounted on suspension and pivotally connected to the crank-beam drive mechanism, distinguishing so that, in order to intensify the process of crumbling of the soil layer, the hinge of fastening the plowshare to the drive mechanism is placed on the extension of the connecting rod from the rocker arm.

2. A device according to claim 1, characterized in that the rocker arm is connected to the connecting rod by means of a slide and is adjustable in length. Sources of information taken into account during the examination 1. USSR author's certificate No. 452299, cl. A 01 D 15/04, 1973.
