Abstract

Изобретение относится к горной промышленности, а именно к режущим инструментам исполнительных органов горных машин, используемых преимущественно для разработки солей и углей без крепких включений и их крепления. Породоразрушающее устройство содержит резцедержатель с клиновидным пазом, в котором расположены клин и резец, клин выполнен с зубчатыми выступами, размещенными в зубчатых впадинах, выполненных на контактирующей с клином поверхности резца. Клин поджат в сторону суженной части клиновидного паза с помощью упругого элемента, который размещен в пазу, выполненном в клине, при этом один конец упругого элемента, выполненного в виде резинового кольца, зафиксирован на клине штифтом, а другой его конец оттянут в сторону суженной части клиновидного паза крюком, закрепленным на корпусе резцедержателя. Повышается технологичность изготовления породоразрушающего устройства при одновременном обеспечении надежного и безлюфтового крепления резца на исполнительном органе горной машины.The invention relates to the mining industry, namely to the cutting tools of the executive bodies of mining machines, used mainly for the development of salts and coals without strong inclusions and their fastening. The rock-breaking device comprises a tool holder with a wedge-shaped groove, in which a wedge and a cutter are located, the wedge is made with toothed protrusions located in the gear depressions made on the cutter surface in contact with the wedge. The wedge is pressed in the direction of the constricted part of the wedge-shaped groove using an elastic element that is placed in a groove made in the wedge, with one end of the elastic element made in the form of a rubber ring fixed on the wedge with a pin, and the other end is drawn in the direction of the constricted part of the wedge-shaped groove hook mounted on the case of the tool holder. The manufacturability of the rock-breaking device is increased while ensuring reliable and backlash-free fastening of the cutter on the executive body of the mining machine.
