DETAILED DESCRIPTION

(6) Referring to FIG. 1, an exemplary machine 100 is illustrated. The exemplary machine 100 is a cold planer. The machine is configured to scarify, remove, mix, or reclaim material from the surface of bituminous, concrete, or asphalt roadways and other surfaces. The machine 100 includes a frame 102, support apparatus 104, a plurality of ground engaging units 106, and a tool (not shown). The frame 102 may include a front end 110, a rear end 112, a first side 114 and a second side 116. The support apparatus 112 is configured to support the frame 102 on a surface. The machine 100 has an engine (not shown). Further, the machine 100 includes other components that are not described herein.

(7) The machine also includes an enclosure compartment 122 for a milling rotor (not shown). The enclosure compartment 122 includes a moldboard 124. The enclosure compartment 124 includes a frame 202 (see FIG. 2). The moldboard 124 is moveable with respect to the frame 202 in a generally vertical direction between an first position and a second position. For the purpose of this disclosure, the moldboard 124 is open or raised when in the first position and the moldboard 124 is closed or lowered when in the second position.

(8) The present disclosure relates to an interfacing arrangement 200 for the moldboard 124. Referring to FIGS. 2 and 3, the interfacing arrangement 200 includes a first pair of components 204 provided on the frame 202. Further, the interfacing arrangement 200 also includes a second pair of components 206 carried on the moldboard 124. As shown, the first and second pair of components 204, 206 are placed on opposing sides 208, 210 of the frame 202. The interfacing arrangement 200 is provided at an upper portion 212 of the moldboard 124 and the frame 202. Alternatively, the interfacing arrangement 200 may be provided at any other suitable location on the moldboard 124 and the frame 202.

(9) Each of the first and second pair of components 204, 206 have a slanted edge 214, 216 respectively. Each of the first and second pair of components 204, 206 have a substantially triangular shape. Referring to FIG. 2, the moldboard 124 is in the second position. In this position, the interfacing components 200 are placed in such a manner that the slanted edges 214 of the first pair of components 204 engage with the slanted edges 216 of the second pair of components 206 to prevent a lateral or sideways movement of the moldboard 124 with respect to the frame 202 when the moldboard 124 is in the second position.

(10) Referring to FIG. 3, the moldboard 124 is shown in the first position. The moldboard 124 may move vertically upwards and downwards with respect to the frame 202 between the second position and the first position. As shown, when the moldboard 124 is in the first position, the first and second pair of components 204, 206 disengage from one another. Additionally, a gap 302 is created between the first and second pair of components 204, 206, allowing the lateral movement of the moldboard 124 relative to the frame 202.

(11) FIGS. 4 and 5 illustrates another interfacing arrangement 400, according to an embodiment of the present disclosure. As described, the first pair of components 404 are provided on the frame 202. The second pair of components 406 are embodied as projections that are circular in shape. When the moldboard 124 is in the second position as in FIG. 4, the circular projection contacts and engages with the slanted edges 414 of the first pair of components 404, preventing the lateral movement of the moldboard 124. As shown in FIG. 5, when the moldboard 124 is in the first position, the gap 502 is created between the first and second pair of components 404, 406 so that the lateral movement of the moldboard 124 can take place. Alternatively, the circular shaped projection may be provided on the frame 202 and the slanted edges 414 may be provided on the moldboard 124.

(12) FIGS. 6 and 7 illustrate yet another interfacing arrangement 600, according to one embodiment of the present disclosure. As shown, the first pair of components 604 are provided on the frame 202. The first pair of components 604 have a generally wedge-shaped appearance including the slanted edge 614. The second pair of components 606 are provided on the moldboard 124. The second pair of components 606 have a generally rectangular shape and a corner of the component that faces the first pair of components 604 has a slanted edge 616. When the moldboard 124 is in the second position, the second pair of components 606 engage with the first pair of components 604 for preventing the lateral movement of the moldboard 124. Referring to FIG. 7, when the moldboard 124 is in the first position, the first pair of components 604 disengage from the second pair of components 606. The gap 702 is created between the slanted edges 614, 616 of the first and second components 604, 606 respectively, allowing the lateral movement of the moldboard 124. Alternatively, the rectangular shaped component may be carried by the frame 202 and the wedge-shaped component may be carried by the moldboard 124.

(13) The shape of the first pair of components 204, 404, 604 and the second pair of components 206, 406, 606 provided in the accompanying drawings are exemplary and do not limit the scope of the present disclosure. The first pair of components 204, 404, 604 and the second pair of components 206, 406, 606 may be made of any suitable metal and attached to the frame 202 and the moldboard 124 using known methods. Further, two or more interfacing arrangements 200, 400, 600 may be provided at different locations on the moldboard 124 and the frame 202.

(14) As described above, the first pair of components 404, 604 may include the slanted edge 414, 614. Alternatively, the second pair of components 406, 606 may include the slanted edge. In one example, both the first and second pair of the components 204, 206 include slanted edges 214, 216. The slanted edge of any one or both the first pair of components 204, 404, 604 and the second pair of components 206, 406, 606 selectively interact with one another, such that the lateral movement of the moldboard 124 is allowed when the moldboard 124 is in the first position and is prevented when the moldboard 124 is in the second position. The first pair of components 204, 404, 604 and the second pair of components 206, 406, 606 are shaped and arranged such that the first pair of components 204, 404, 604 and the second pair of components 206, 406, 606 mate with one another for locking the moldboard 124 when in the second position. Also, first pair of components 204, 404, 604 and the second pair of components 206, 406, 606 are disengaged from one another and allow the lateral movement of the moldboard 124 when the moldboard 124 is in the first position.

INDUSTRIAL APPLICABILITY

(15) The present disclosure relates to the interfacing arrangement 200, 400, 600 for the moldboard 124 of the machine 100. Referring to FIG. 8, a method 800 for controlling the movement of the moldboard 124 with respect to the frame 202 of the machine 100 is provided. At step 802, the method includes providing the interfacing arrangement 200, 400, 600 including the first pair of components 204, 404, 604 carried by the frame 202 and the second pair of components 206, 406, 606 carried by the moldboard 124. The first pair of components 404, 604 or both the first and second pair of components 204, 206 have respective slanted edges 414, 614 or 214, 216.

(16) At step 804, the method includes operating the moldboard 124 between the first position and the second position. At step 806, the first pair of components 204, 404, 604 and the second pair of components 206, 406, 606 are configured to allow a lateral movement of the moldboard 124 when the moldboard 124 is in the first position. At step 808, the first pair of components 204, 404, 604 and the second pair of components 206, 406, 606 are configured to engage one another to prevent the lateral movement of the moldboard 124 when the moldboard 124 is in the second position.
