Abstract
The invention discloses a screening roller of a screening feeder. The transition section of the screening roller of the existing screening feeder is a straight section, and in the transportation process, when materials are pressed towards adjacent rollers by the screening roller, the straight section of the screening roller linearly downwards presses the materials, the friction time is long, resistance is increased, the materials are even clamped between two rollers, normal operation of the screening feeder is affected, and more seriously, a speed reducer can be damaged. The screening roller of the screening feeder comprises a rotating shaft and a plurality of oval roller bodies arranged along the axial direction of the rotating shaft. The screening roller can achieve a function of conveying the materials, and when the adjacent screening rollers rotate, the materials are fed between the screening rollers, the friction time of the oval outer contour and the materials is short, resistance is reduced, and therefore the materials can be conveyed smoothly, material clamping is avoided, and device safety is effectively protected.
Description
[technical field]
The present invention relates to a kind of screening feeding machine, especially the roller in the screening feeding machine.
[background technology]
Screening feeding machine is used for the industries such as building materials, metallurgy, coal, chemical industry, is mainly used in along continuous straight runs and carries various loose shapes, bulk materials.In cement industry, be used for the conveying from the ore storage bin bottom to disintegrating machine such as block shale, sandstone or coal, play continuous flow rate, improve the effect of crushing efficiency.The high-speed motion that each roll shaft of screening section is made continuous uniform in the screening feeding machine reaches the lower minor diameter material of sieve, transports larger material purpose.
The changeover portion of screening roller is one section flat segments in the existing screening feeding machine, does not have radian.In operation process, when material is sized roller and presses to adjacent rollers, screening roller flat segments straight line presses down material, increased the time of material friction, strengthened resistance, even material can be stuck between two rollers, the lighter can affect the normal operation of screening feeding machine, severe one can be destroyed reducer gear, even damages reductor.
Therefore, how avoiding material to be stuck between the two screening rollers, is the present technical issues that need to address of those skilled in the art.
[summary of the invention]
The invention provides a kind of screening roller of screening feeding machine, material is sent process to and can be avoided material to block, and changes simultaneously and safeguard also to make things convenient for.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of screening roller of screening feeding machine comprises rotating shaft and the some roll bodies that axially arrange along rotating shaft, and described roll body is oval roll body.
Further, the excircle of described rotating shaft is to arranging described oval roll body, and described oval roll body comprises left roll body and the right roll body of C shape, and described left roll body is fixedly connected with and clamps rotating shaft with right roll body.
Further, upwards be provided with the groove that connects described left roll body and right roll body the week of described rotating shaft.
Further, the end face that described left roll body is relative with right roll body is provided with the screwed hole that runs through, and is connected by screw the screwed hole on left roll body and the right roller.
Further, the end face that described left roll body is relative with right roll body is provided with projection, right roll body is provided with the corresponding groove that connects described projection, the sidewall of projection is provided with through hole, the corresponding described through hole of the both sides inwall of groove is provided with the connecting hole that runs through, and rivets described left roll body and right roll body by rivet cross-under through hole and connecting hole.
Beneficial effect of the present invention:
Screening roller of the present invention changes roll body into ellipsoidal structure, inherited outside the function of convey materials, in the time of adjacent screening roller running, when the roll body of last screening rod presses down material and the tangent angle of a rear screening roller can not produce straight line, shorten with the fraction time of material, resistance reduces, and material just can smooth delivery of power.Greatly reduce the phenomenon that gets stuck, effectively protected the safety of equipment.
And what roll body was detachable is arranged in the rotating shaft, and one of them roll body damages and just can change immediately, convenient for maintaining, and in same rotating shaft replaceable different big or small roll bodies, thereby adapt to the requirement of different step sizings.
These characteristics of the present invention and advantage will be below the specific embodiment, accompanying drawing in detailed exposure.
[description of drawings]
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram of shaft of the present invention;
Fig. 3 is the schematic diagram of oval roll body in the embodiment of the invention one;
Fig. 4 is the schematic diagram of oval roll body in the embodiment of the invention two.
[specific embodiment]
The invention provides a kind of screening roller of screening feeding machine, comprise rotating shaft and the some roll bodies that axially arrange along rotating shaft, described roll body is oval roll body.Realize outside the function of convey materials, in the time of adjacent screening roller running, material is sent between the screening roller, and the fraction time of oval outline and material shortens, and resistance reduces, so material just can smooth delivery of power; Prevent the phenomenon that gets stuck, effectively protected the safety of equipment.
Be explained and illustrated below in conjunction with the accompanying drawing of the embodiment of the invention technical scheme to the embodiment of the invention, but following embodiment is the preferred embodiments of the present invention only, is not whole.Based on the embodiment in the embodiment, those skilled in the art belong to protection scope of the present invention at lower other embodiment that obtains of the prerequisite of not making creative work.
