Abstract
The utility model discloses an adjusting fork rack of a small underground coal cutter. The adjusting fork of the small underground coal cutter comprises a fixing main shaft, wherein a pair of fixing fork shafts are arranged at the tail part of the fixing main shaft; an adjusting protruding piece is respectively arranged at the tail end of each fixing fork shaft; each adjusting protruding piece comprises a fish fin shaped protruding piece main body; a first adjusting through hole, a second adjusting through hole, a third adjusting through hole and a fourth adjusting through hole are formed in the protruding piece main body. Due to adoption of the four adjusting through holes in the adjusting protruding pieces of the adjusting fork rack of the small underground coal cutter, a user can select different positions for mounting a drill bit or a water nozzle, the conventional screw adjustment is replaced, and the reliability and usability of the underground coal cutter are greatly improved. Besides, as a locking bayonet is arranged at the tail part of the protruding piece main body, the fastness in fixing the drill bit or the water nozzle is further improved, and the practicability is high.
Description
Technical field
The utility model relates to a kind of coal mining equipment, or rather, is a kind of adjusting crotch of small-sized silo shearer.
Background technology
Silo shearer is a kind of common coal excavating gear, by utilizing drill bit or hydraulic giant to carry out coal mining activity.The position general using screw of the drill bit of existing coal-winning machine or hydraulic giant regulates, and because the vibration of coal-winning machine is very big, screw is easily loosening, easily causes drill bit or hydraulic giant to come off, and causes danger.
Summary of the invention
The utility model is mainly to solve the existing technical problem of prior art, thereby a kind of adjusting crotch of small-sized silo shearer is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of adjusting crotch of small-sized silo shearer, the adjusting crotch of described small-sized silo shearer comprises a fixed main shaft, the afterbody of described fixed main shaft is provided with a pair of fixing fork shaft, described fixation fork the tip of the axis is respectively equipped with an adjusting tab, the tab main body that described adjusting tab comprises a fin shape, described tab main body is provided with one first and regulates through hole, one second regulates through hole, one the 3rd regulates through hole and the 4th to regulate through hole, the first described adjusting through hole, second regulates through hole, the 3rd regulates through hole and the 4th to regulate the size of through hole to increase gradually.
As the utility model preferred embodiment, the afterbody of described tab main body is provided with a locking bayonet socket.
The adjusting crotch utilization of small-sized silo shearer of the present utility model regulates four on tab to regulate through hole, user can select different positions that drill bit or hydraulic giant are installed, replace traditional screw and regulated, greatly improved reliability and the ease for use of silo shearer.In addition, because the afterbody of tab main body is provided with locking bayonet socket, further improve the fixing fastness of drill bit or hydraulic giant, practical.
