Further, described slide is connected with a screw rod axially overlapped with bull ring radial direction near the one end at bull ring center, described screw rod outward and cover have the swivel nut with its threaded engagement, described swivel nut rotates in a circumferential direction, axial restraint.
Further, described grinding roller frame is provided with the coaming plate upwards extended, and slide surrounds within it by said coaming plate, and described coaming plate inner surface is provided with the backstay with screw coaxial, described backstay overcoat has spring, and described both ends of the spring is connected with coaming plate inwall and slide outer wall respectively.
Further, described main shaft is provided with the through hole coaxial with it, through an elevating lever in described through hole, described elevating lever is driven by the drive unit below body and is elevated in through hole, the top of described elevating lever connects a flat board, the lower edge of described flat board is provided with the ring-type scraper plate to downward-extension, and described scraper plate declines with elevating lever and contacts with bull ring inner surface.
The beneficial effects of the utility model: raymond mill of the present utility model, comprise main frame, main frame comprises body, bull ring, main shaft, grinding roller frame, shaft of grinding roller and grinding roller, described bull ring is fixed in body, described main shaft and bull ring are coaxially and penetrate from the bottom to top in body, described grinding roller frame to be placed on main shaft and to connect with main shaft key, described shaft of grinding roller is installed on grinding roller frame, described grinding roller is coaxially placed on shaft of grinding roller outward also can around its axis rotation, when described grinding roller revolves round the sun with main shaft and bull ring inner surface tangent, described grinding roller frame upper surface has chute along bull ring radial direction, to snap in described chute and to be sliding combined with slide with it, described shaft of grinding roller is arranged on slide.Can grinding roller be made to continue with bull ring tangent along bull ring is radially outward mobile by moving sliding base after the contact surface of bull ring and grinding roller is impaired, guarantee material grinding effect be constant.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the zoomed-in view of I part in Fig. 1.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in the figure be host machine part in raymond mill, comprise a fixing body 1, be provided with bull ring 2, grinding roller 6 and main shaft 3 in body 1, wherein the axis vertical of bull ring 2, and fixing; Grinding roller 6 is supported by the shaft of grinding roller 5 coaxial with it and can around its axis rotation, and shaft of grinding roller 7 is arranged on slide 7; Main shaft 3 and bull ring are coaxially arranged, main shaft 3 there is grinding roller frame 4 by binding female connector, grinding roller frame 4 upper surface has chute 41 along the radial direction of bull ring 2, slide 7 snaps in chute 41 and also can move radially along track length direction and bull ring under external force, main shaft 3 drives lower rotation by belt drive unit, grinding roller 6 is driven to revolve round the sun around main shaft 3 around main shaft 3 rotation and grinding roller 6, tangent at grinding roller 6 and bull ring 2 inner peripheral surface.Material enters in body from body 1 upper feeding mouth, grinding roller 6 revolves round the sun around main shaft 3, simultaneously grinding roller 6 be subject to the effect of the frictional force of bull ring 2 can around shaft of grinding roller 5 rotation, grinding roller 6 revolution with in rotation process together with bull ring 2 by material grinding, along with the accumulation of working time, grinding roller 6 can produce with the contact surface of bull ring 2 and weares and teares and make to produce gap between the two, cause abrasive material decreased effectiveness, now, can moving sliding base 7 be that grinding roller is tangent with bull ring along bull ring 2 radially outward mobile continuation, and slide 7 is connected with grinding roller frame by bolt, the position that wherein on grinding roller frame, corresponding bolt passes will be provided with elongated hole, so just can ensure that slide can be fixed after moving.
