The length of the upper end opening of the recovery case 41 is greater than the distance between the two first sealing plates 223 and less than the width of the shield 2.
In this embodiment, the third driving member 43 is specifically a driving motor, and the material outlet 411 is disposed at an end of the bottom of the recycling case 41 far away from the third driving member 43. The third driving member 43 can drive the rotating shaft 42 to rotate, and the oil stain falling into the recycling housing 41 is led to the material outlet 411 through the helical blade on the periphery of the rotating shaft 42.
Further, the material outlet 411 is connected to one end of a conduit, the other end of the conduit is communicated with the recovery box, and the oil stain flowing into the recovery shell 41 is discharged from the material outlet 411 and enters the recovery box along the conduit, so that the recovery of workers is facilitated.
In the embodiment, the bottom of the protective cover 2 is provided with a through hole communicated with the outside; typically, the through hole is covered by a sealing cover. Because a small amount of oil stain does not flow into the recovery shell 41, but is gathered and deposited at the bottom of the protection cover 2 downwards, when the protection cover is overhauled after long-time work, a small amount of deposited oil stain can be discharged through the through hole at the bottom of the protection cover 2. The oil stain quantity of the part is less, and the part is not attached to the gear, so that the transmission of the gear is not influenced.
Referring to fig. 13, in the present embodiment, the height of the axis of the screw shaft 314 in the brush head assembly 31 from the ground is equal to the height of the axis of the open gear 1 from the ground; the recovery housing 41 is disposed between the brush head assembly 31 and the ground, and preferably, the recovery housing 41 is disposed at a lower position so that the oil dirt flowing down from the open gear 1 can vertically fall into the recovery housing 41.
The working principle of the application is as follows:
when the open gear of the mill needs to be cleaned, the open gear 1 is slowly rotated clockwise, and simultaneously, the first driving piece 313, the second driving piece 324 and the third driving piece 43 are started; under the driving action of the first driving element 313, the brush head body 311 reciprocates along the axial direction of the open gear 1, and brushes dirt between teeth of the open gear 1 to two ends of the open gear 1; then, the oil stain flows downwards into the recovery casing 41 from the gaps between the second sealing plate 212 and the first sealing plate 223 and the open gear 1, and flows out from the material outlet 411 under the driving action of the third driving element 43; under the driving action of the second driving member 324, the rubber stoppers 321 at two ends of the open gear 1 are respectively contacted with two end surfaces of the open gear 1, so that dirt attached to the two end surfaces of the open gear 1 flows downwards into the recovery mechanism 4 under the wiping action of the rubber stoppers 321; after the open gear 1 rotates for one or several circles, the cleaning of the open gear of the mill is completed.
In this embodiment, the brush head body 311 can rotate relative to the brush head holder 312 with the rotation of the opening gear 1.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not depart from the spirit of the corresponding technical solutions of the embodiments of the present invention.
