Description

Technical Field

[0001] The invention relates to the technical field of road engineering equipment, and in particular to an opening structure of a side plate of a milling machine, a side plate and a milling machine. Background Art

[0002] With the continuous development of milling machines, there is a higher demand for the replacement efficiency of the milling drum. The current drum replacement method requires disassembly of the transmission door box, reducer and other components, and then the milling drum is pulled out from the bearing support end.

[0003] Since the milling drum needs to be pulled out from the bearing support end, the side panel needs to be designed to be an openable structure. The current mainstream side panel opening and closing methods mainly include the following two:

[0004] The first method: single hinge + screw fixing. Since directly opening the side panel will cause interference between the support flange and the bearing support, the side panel fixing screws and the screws on the support flange need to be removed, and then the support flange is taken out. Only then can the side panel be opened. In addition, due to the obstruction of the side slide plate, it is very difficult to remove the screws on the support flange. Sometimes, it is even necessary to remove the side slide plate before removing the support flange. The workload is large and it takes a long time, and it is impossible to quickly change the drum.

[0005] The second method: hinge + tapered hole flange, which uses a tapered hole flange to match the bearing support. When the side panel is opened, the flange and the bearing support can avoid each other and will not interfere with each other. However, the use of tapered hole flanges has very high requirements for its processing accuracy. It is necessary to ensure the coordination of the flange and the bearing, and also to ensure that the flange and the bearing will not interfere with each other during the rotation of the hinge.

[0006] Therefore, for those skilled in the art, how to provide a new opening structure for the side panel of the milling machine so that the side panel can be rotated out without removing the supporting flange, and at the same time the structure is simpler than the existing technology and is easier to process, is of more practical significance. Summary of the invention

[0007] In order to improve at least one of the above-mentioned technical problems, an object of the present invention is to provide an opening structure of the side panel of a milling machine, so that the side panel can be rotated out without removing the supporting flange. At the same time, the structure is simpler than the prior art and is easier to process.

[0008] Another object of the present invention is to provide a side plate of a milling machine.

[0009] Another object of the present invention is to provide a milling machine comprising the above-mentioned opening structure.

[0010] In order to achieve the above-mentioned objectives, the technical solution of the first aspect of the present invention provides an opening structure of the side plate of a milling machine, wherein a milling drum is arranged in the milling machine, and a supporting flange is arranged on the side plate, and the supporting flange and the bearing support of the milling drum abut against each other, and the opening structure comprises: a first connecting member, one end of the first connecting member is used to be rotatably connected with one of the side plate and the milling machine body; a second connecting member, one end of the second connecting member is rotatably connected with the other end of the first connecting member, and the other end of the second connecting member is used to be rotatably connected with the other of the side plate and the milling machine body; the first connecting member and the second connecting member cooperate to enable the side plate to translate along the axial direction of the bearing support to move away from or approach the milling drum, and when the side plate translates to a first preset position, the supporting flange and the bearing support can always remain non-contact when the side plate rotates relative to the milling drum, and when the side plate translates to a second preset position, the supporting flange and the bearing support of the milling drum abut against each other.

[0011] Specifically, the opening structure provided by the technical solution of the first aspect of the present invention includes a first connecting member and a second connecting member that are rotatably connected to each other, so that the first connecting member can move relative to the second connecting member, and the end of the first connecting member away from the second connecting member can make a translational movement relative to the end of the second connecting member away from the first connection. At the same time, the first connecting member is rotatably connected to one of the side plate and the milling machine body of the milling machine, and the second connecting member is rotatably connected to the other of the side plate and the milling machine body of the milling machine, so that during the movement of the first connecting member relative to the second connecting member, there is no relative rotation between the side plate and the milling machine body, so that during the movement, the side plate can also translate along the axial direction of the bearing support of the milling drum, and the support flange on the side plate is separated from the bearing support without interfering with each other. After the translation process is completed and the side plate is away from the milling machine body, the side plate can be rotated relative to the milling machine body by rotating the first connecting member with one of the side plate of the milling machine and the milling machine body, or by rotating the second connecting member with the side plate of the milling machine and the other of the milling machine body, thereby completing the opening of the side plate, so that the milling drum can be pulled out of the milling machine without removing the side plate.

[0012] Compared with the related technology, the opening structure provided by this scheme increases the translational movement space of the side plate relative to the milling machine body, so that the side plate and the milling machine body can translate relative to each other, and can also rotate relative to each other after the relative translational movement, which provides conditions for the separation of the side plate and the milling drum of the milling machine, and at the same time limits the interference between the bearing support and the support flange. It has a simple structure and is easy to install. At the same time, it does not require major modifications to the structure of the milling machine. The processing is relatively simple and the cost is low. When replacing the milling drum, there is no need to remove the side plate as a whole, which improves the replacement efficiency.

[0013] It can be understood that the first connecting member and the second connecting member both have a certain length, so that during the translation of the side plate, the side plate reciprocates between the first preset position and the second preset position, and when the side plate is in the second preset position, the support flange of the side plate and the bearing support of the milling drum are abutted against each other, and when the side plate needs to be rotated, the side plate is translated to the first preset position relative to the milling machine body, so that the support flange and the bearing support of the milling drum are separated, and a certain gap distance exists between them, and the gap distance provides a rotation space for the side plate, and the gap distance is large enough to make the side plate far enough away from the milling drum, so that the activity space for the side plate to rotate continues to exist, so that during the rotation of the side plate, the support flange and the bearing support can avoid each other and not contact, thereby greatly reducing the possibility of interference between the support flange and the bearing support, and at the same time, after the side plate rotates relative to the milling machine body, there is enough space for the milling drum to be directly pulled out of the milling machine body, eliminating the work of removing the side plate or the support flange, and effectively improving the replacement efficiency of the milling drum.

[0014] In addition, the opening structure in the above technical solution provided by the present invention may also have the following additional technical features:

[0016] In the above technical solution, the rotating shaft extends in the vertical direction; and / or a stopper is provided at the end of the rotating shaft, and the stopper abuts against the first connecting member or the second connecting member.

[0017] In any of the above technical solutions, the number of the first connecting members is two, and the two first connecting members are respectively arranged at the axial ends of the rotating shaft; and / or the number of the second connecting members is two, and the two second connecting members are respectively arranged at the axial ends of the rotating shaft.

[0018] In any of the above technical solutions, the first connecting member and the second connecting member have the same size.

[0019] The technical solution of the second aspect of the present invention provides a side panel of a milling machine, and the side panel is provided with an opening structure as described in any one of the technical solutions of the first aspect.

[0020] The side plate of the milling machine provided by the technical solution of the second aspect of the present invention comprises the sliding part described in any one of the technical solutions of the first aspect, and thus has all the beneficial effects of any of the above technical solutions, which will not be described in detail here.

[0021] In addition, it is worth mentioning that the side panel provided with the above-mentioned opening structure can perform translational movement relative to the milling machine body, so that the side panel and the milling machine body are not limited to being connected only by rotation, but can also be connected in a sliding manner. Correspondingly, the opening method of the side panel is expanded, so that the side panel can be suitable for a variety of milling machines. At the same time, since the processing method of the opening structure is simple, it is conducive to maximizing standardization.

[0022] The technical solution of the third aspect of the present invention provides a milling machine, comprising: a milling machine body, in which a milling drum is arranged; a side plate, which is provided with a support flange, and the support flange and the bearing support of the milling drum are abutted against each other to support the milling drum; and an opening structure as described in any one of the technical solutions of the first aspect, wherein the milling machine body and the side plate are connected through the opening structure.

[0023] The milling machine provided by the technical solution of the third aspect of the present invention includes the opening described in any one of the technical solutions of the first aspect, and thus has all the beneficial effects of any of the above technical solutions, which will not be repeated here.

[0024] It is also worth mentioning that the milling machine body in this solution can use its own rotating parts, such as bolts, to be rotatably connected to the first connecting part or the second connecting part of the opening structure, without the need to modify other structures, which can further reduce the modification cost.

[0038] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0040] Refer to the following Figures 1 to 6 An opening structure 1 , a side plate 2 , and a milling machine according to some embodiments of the present invention are described.

[0041] Some embodiments of the present invention provide an opening structure 1, comprising a first connecting member 11 and a second connecting member 12, wherein the first connecting member 11 and the second connecting member 12 are rotatably connected.

[0042] Embodiment 1

[0043] The opening structure 1 provided in the present application is used for a milling machine. A milling drum is arranged in the milling machine, and a supporting flange 21 is arranged on the side plate 2.

[0044] Specifically, Figure 1 As shown, the opening structure 1 includes a first connecting member 11 and a second connecting member 12 that are rotatably connected. The first connecting member 11 and the second connecting member 12 are rotatably connected so that the first connecting member 11 and the second connecting member 12 can rotate relative to each other, thereby making the end of the first connecting member 11 away from the second connecting member 12 and the end of the second connecting member 12 away from the first connecting member 11 approach or move away from each other. At the same time, one end of the first connecting member 11 is rotatably connected to the side plate 2, and one end of the second connecting member 12 is rotatably connected to the milling machine body 3. In the process of making the end of the first connecting member 11 away from the second connecting member 12 and the end of the second connecting member 12 away from the first connecting member 11 approach or move away from each other, the side plate 2 and the milling machine body 3 do not rotate relative to each other, but perform relative translational movement to approach or move away from each other.

[0045] The present application sets an opening structure 1 so that the side plate 2 is suitable for translation along the axial direction of the bearing support 31 to move away from or close to the milling drum. Then, the first connecting member 11 and the second connecting member 12 are rotatably connected, or one end of the first connecting member 11 is rotatably connected to the side plate 2, or one end of the second connecting member 12 is rotatably connected to the milling machine body 3, so that the side plate 2 can rotate relative to the milling machine body 3. The side plate 2 is first translated and then rotated relative to the milling machine body 3 through the opening structure 1, so that the milling drum can be pulled out of the milling machine without removing the side plate.

[0046] It can be understood that the first connecting member 11 and the second connecting member 12 both have a certain length, so that during the translation of the side plate 2, the side plate 2 reciprocates between the first preset position and the second preset position. When the side plate 2 is in the second preset position, the support flange 21 of the side plate 2 and the bearing support 31 of the milling drum are in contact with each other. When the side plate 2 needs to rotate, the side plate 2 is translated to the first preset position relative to the milling machine body, so that the support flange 21 and the bearing support 31 of the milling drum are separated, and a certain gap distance is left between them. The gap distance provides rotation space for the side plate 2. The gap distance is large enough so that the side plate 2 is far enough away from the milling drum, so that there is continuous space for the side plate 2 to rotate, so that during the rotation of the side plate 2, the support flange 21 and the bearing support 31 can avoid each other and do not contact each other, thereby greatly reducing the possibility of interference between the support flange 21 and the bearing support 31. At the same time, after the side plate 2 rotates relative to the milling machine body, there is enough space for the milling drum to be directly pulled out of the milling machine body, eliminating the work of removing the side plate 2 or the support flange 21, and effectively improving the replacement efficiency of the milling drum.

[0047] Compared with the related art, this embodiment increases the translational movement space of the side plate 2 relative to the milling machine body 3 by setting a sliding part, provides conditions for the separation of the side plate 2 and the milling drum of the milling machine, limits the interference between the bearing support 31 and the support flange 21, has a simple structure and is easy to install. At the same time, it does not require major modifications to the structure of the milling machine, and the cost is low. When replacing the milling drum, there is no need to remove the side plate 2 as a whole, which improves the replacement efficiency.

[0048] It is understandable that, in some embodiments, one end of the first connecting member 11 is rotatably connected to the milling machine body 3 , and one end of the second connecting member 12 is rotatably connected to the side plate 2 .

[0049] Embodiment 2

[0050] On the basis of the first embodiment, further, Figure 2 and Figure 3 As shown, the opening structure 1 also includes: a rotating shaft 13; the first connecting member 11 is in the shape of a long rod, and a first through hole is provided at the other end of the first connecting member 11; the second connecting member 12 is in the shape of a long rod, and a second through hole is provided at one end of the second connecting member 12; the rotating shaft 13 is passed through the first through hole and the second through hole to enable the first connecting member 11 to be hinged to the connecting member.

[0051] It can be understood that there are various ways of rotationally connecting the first connecting member 11 and the second connecting member 12, such as hinge connection, ball joint connection, etc., wherein the hinge connection method includes pivot connection, hinge connection, etc.

[0052] By setting a rotating shaft 13 between the first connecting member 11 and the second connecting member 12, a hinged connection is formed, and the first connecting member 11 and the second connecting member 12 rotate around the rotating shaft 13, so that the first connecting member 11 and the second connecting member 12 rotate in the same plane, which is more stable and reliable. Among them, the size of the first through hole and the size of the second through hole are both adapted to the rotating shaft 13, which can achieve a better rotation matching effect. At the same time, the first through hole and the second through hole are set to coaxial rotation through the rotating shaft 13, so that the first connecting member 11 and the second connecting member 12 rotate in the same plane, which can make the side panel 2 translate along a fixed route, thereby limiting the opening route of the side panel 2 in the translational movement, which helps to improve the stability of the opening structure 1. The rotating shaft 13 in this embodiment has a simple structure, is easy to set up, and is easy to operate. Compared with rotation connection methods such as ball joints, it is more helpful to realize the opening process of the side panel 2.

[0053] In addition, it can be understood that the first connecting member 11 and the second connecting member 12 can also be connected to the side plate 2 and the milling machine body 3 respectively in a hinged manner.

[0054] Embodiment 3

[0055] On the basis of the above embodiments, further, Figure 3 and Figure 4 As shown, the rotation axis 13 extends in the vertical direction.

[0056] By setting the rotating axis 13 to extend in the vertical direction, the rotating axis 13 line of the opening structure 1 extends in the vertical direction, and the movement trajectory of the end of the side panel 2 away from the rotating axis 13 is horizontal, so that the side panel 2 can remain relatively stable during the rotation process. Compared with the embodiment in which the rotating axis 13 line of the opening structure 1 extends in the horizontal direction or extends obliquely, there is no need to set up other additional structures to fix the side panel 2, which is conducive to further reducing the difficulty of installation and maintenance, and is convenient for maintenance personnel to check, repair and load and unload the milling drum, thereby further reducing the difficulty of maintenance.

[0057] Embodiment 4

[0058] On the basis of the above embodiments, further, Figure 3 and Figure 4 As shown, a stopper 14 is provided at the end of the rotating shaft 13 , and the stopper 14 abuts against the first connecting member 11 or the second connecting member 12 .

[0059] By setting the stopper 14, the stability of the connection between the first connecting member 11, the second connecting member 12 and the rotating shaft 13 can be improved, and the possibility of the first connecting member 11 or the second connecting member 12 being separated from the rotating shaft 13 during the translation or rotation of the side panel 2 can be reduced, thereby improving the reliability and stability of the opening structure 1.

[0060] Optionally, the rotating shaft 13 is a step bolt, and the first connecting member 11 and the second connecting member 12 are rotationally connected to the step of the step bolt; the stop member 14 is a nut, and the nut is threadedly connected to the screw of the step bolt, so that the first connecting member 11 and the second connecting member 12 are limited between the nut and the bolt cap of the step bolt by the nut.

[0061] It can be understood that in the case where two first connecting members 11 or two second connecting members 12 are provided on the rotating shaft 13, a limiting structure and a stop member 14 can be provided on the side panel 2 or the milling machine body 3 to limit the axial movement of the first connecting member 11 and the second connecting member 12 along the rotating shaft 13, thereby improving the reliability and stability of the opening structure 1.

[0062] Embodiment 5

[0063] On the basis of the above embodiments, further, Figure 3 and Figure 4 As shown, there are two first connecting members 11 , which are respectively arranged at two axial ends of the rotating shaft 13 ; there are two second connecting members 12 , which are respectively arranged at two axial ends of the rotating shaft 13 .

[0064] The opening and closing structure provided in this embodiment includes two first connecting members 11 and two second connecting members 12, which are respectively rotatably connected to the rotating shaft 13. At the same time, by arranging the two first connecting members 11 and the two second connecting members 12 at the upper and lower ends of the rotating shaft 13, the translational movement of the rotating member can be made smoother, so as to improve the use stability of the opening and closing structure. At the same time, by arranging the two first connecting members 11 and the two second connecting members 12, the support for the side panel 2 is improved, so that the side panel 2 is more stable during translation or rotation.

[0065] In some embodiments, the first connecting member 11 and the second connecting member 12 have the same size.

[0066] By setting the sizes of the first connecting member 11 and the second connecting member 12 to the same specifications, the cost of processed parts can be reduced and the standardization of parts can be improved.

[0067] In some other embodiments, the first connecting member 11 and the second connecting member 12 may be provided with different specifications. For example, the thickness of the first connecting member 11 and the second connecting member 12 located at the bottom is slightly thicker than that of the first connecting member 11 and the second connecting member 12 located at the top, and the structural strength can be improved by increasing the thickness. For another example, the first connecting member 11 and the second connecting member 12 connected to the side plate 2 is slightly longer than that connected to the milling machine body 3, and the possibility of interference between the side plate 2 and the mounting structure such as the hinge seat 32 provided on the milling machine body 3 can be reduced.

[0068] Embodiment 6

[0069] Some embodiments of the present invention provide a side panel 2 including the opening structure 1 in any of the above embodiments.

[0070] like Figure 2 As shown, the side panel 2 provided with the opening structure 1 provided in the present embodiment can perform translational movement relative to the milling machine body 3 on the basis of rotational movement, and accordingly the opening method of the side panel 2 is expanded, so that the side panel 2 can be applied to a variety of milling machines, which is conducive to maximizing standardization.

[0071] Embodiment 7

[0072] Some embodiments of the present invention provide a milling machine, such as Figures 3 to 5 As shown, it includes: a milling machine body 3, in which a milling drum is arranged; a side plate 2, which is provided with a supporting flange 21, and the supporting flange 21 and the bearing support 31 of the milling drum are abutted against each other, and are used to support the milling drum; and an opening structure 1 in any of the above embodiments, and the milling machine body 3 and the side plate 2 are connected through the opening structure 1.

[0073] Specifically, Figure 3 The side plate 2 on the milling machine is in a closed state, the side plate 2 is in a second preset position, the support flange 21 and the bearing support 31 of the milling drum are in abutment with each other, and the side plate 2 provides a stable support to the milling drum; Figure 4 When the side plate 2 is in the first preset position, the support flange 21 and the bearing support 31 of the milling drum are separated by relative rotation between the first connecting member 11 and the second connecting member 12; Figure 5 After the side plate 2 is in the first preset position, it is rotated to open the side plate 2. At this time, the milling drum can be taken out of the milling machine body 3 for replacement.

[0074] Since the milling machine provided in this embodiment includes the opening mechanism in the above embodiments, it has all the beneficial effects in any of the above embodiments, which will not be described in detail here.

[0075] In addition, the milling machine provided in this embodiment can use its own rotating parts, such as bolts, etc., and there is no need to modify other structures, which can further reduce the modification cost.

[0076] Embodiment 8

[0077] On the basis of Example 7, Figure 5 and Figure 6 As shown, the opening structure 1 is connected to a hinge structure; the hinge structure includes a hinge seat 32 , which is connected to the milling machine body 3 and is hinged to one of the first connecting member 11 and the second connecting member 12 of the opening structure 1 .

[0078] The opening structure 1 of the milling machine provided in this embodiment is a hinge structure, which is fixedly connected to the side panel 2 through a connecting portion, and fixedly connected to the milling machine body 3 through a hinge seat 32, thereby making installation more convenient and improving the connection strength, thereby preventing the side panel 2 from shaking relative to the milling machine body 3 and improving the stability of the opening structure 1.

[0079] Furthermore, a mating portion 22 is provided on the side panel 2, and the mating portion 22 is arranged on the side of the side panel 2 for connecting the opening structure 1; the mating portion 22 extends in a direction away from the milling machine body 3, and an avoidance space 23 for avoiding the hinge seat 32 is formed between the mating portion 22 and the side panel 2.

[0080] By setting the matching portion 22, the opening structure 1 is kept at a certain distance from the side panel 2 body, avoiding interference between the side panel 2 body and the opening structure 1 during the opening process, making the opening and closing process smoother. Optionally, the matching portion 22 is a long strip connecting rod, and the extending direction of the connecting rod is perpendicular to the plane where the side panel 2 is located. At the same time, by setting the matching portion 22, the connection between the side panel 2 and the opening structure 1 is facilitated.

[0081] Embodiment 9

[0082] Based on any of the above embodiments, Figure 6 As shown, further, the number of the opening structures 1 is two, and the two opening structures 1 are coaxially arranged.

[0083] The milling machine provided in this embodiment is provided with two opening structures 1, and the rotating shafts 13 of the two opening structures 1 are coaxially arranged. By providing two opening structures 1, they can be respectively arranged at the upper and lower ends of the same side of the side plate 2, so that the rotation and translation of the side plate 2 are more stable, so as to improve the use stability of the opening and closing structure. At the same time, a long rotating shaft 13 is taken out of two short rotating shafts 13, which reduces the length of the rotating shaft 13, and at the same time reduces the possibility of interference between the middle section of the omitted rotating shaft 13 and the milling machine body 3 or other equipment, further improving the use reliability.

[0084] It is understandable that the number of the opening structures 1 may be two, three or more. The specific number of the opening structures 1 is related to the length of the side plate 2 along the direction of the rotation axis 13 .

[0085] The following is a specific embodiment to illustrate the opening structure 1 of the side panel 2 of the milling machine provided in the present application, the specific structure and working principle of the side panel 2 and the milling machine.

[0086] With the continuous development of milling machines, there is a higher demand for the replacement efficiency of the milling drum. The current drum replacement method requires the disassembly of the transmission door box, reducer and other components, and then the milling drum is pulled out from the bearing support 31 end. Since the milling drum needs to be pulled out from the bearing support 31 end, the side panel 2 needs to be designed as an openable structure. The current mainstream side panel 2 opening and closing methods mainly include the following two types: 1. Single hinge + screw fixation. Since directly opening the side panel 2 will cause the flange to interfere with the bearing support 31, the side panel 2 fixing screws and the screws on the support flange 21 need to be removed, and then the support flange 21 is taken out. Only then can the side panel 2 be opened. 2. Single hinge + tapered hole flange, which uses a tapered hole flange to cooperate with the bearing support 31. When the side panel 2 is opened, the flange and the bearing support 31 can avoid each other and will not interfere.

[0087] However, the above two side panel 2 opening and closing methods have the following problems: for the combination structure of single hinge + screw fixing, due to the obstruction of the side slide plate, the screw removal process on the support flange 21 is very difficult, and sometimes it is even necessary to remove the side slide plate before removing the support flange 21. The workload is large and it takes a long time, and it is impossible to quickly change the drum. For the combination structure of single hinge + conical hole flange, the use of conical hole flange has very high requirements for its processing accuracy. It is necessary to ensure the coordination between the flange and the bearing, and it is also necessary to ensure that the flange and the bearing will not interfere with each other during the rotation of the hinge.

[0088] To address the above limitations, the present application provides an opening structure 1 of the side panel 2, and the side panel 2 is first translated and then rotated out through the opening structure 1 without removing the supporting flange 21. The opening structure 1 is simple in structure and easy to process.

[0089] Specifically, a connecting rod mechanism is used between the side plate 2 and the milling machine body 3, and at least two connecting rods (such as the first connecting member 11 and the second connecting member 12) are used to connect the side plate 2 to the milling machine body 3. When the drum needs to be replaced, before rotating the side plate 2, the entire side plate 2 is first translated outward. After confirming that the bearing support 31 flange 21 is completely disengaged from the bearing support 31, the side plate 2 is rotated. At this time, the flange and the bearing support 31 will not interfere with each other.

[0090] The milling machine includes a side plate 2, a milling machine body 3, a bearing support 31, a support flange 21, a first connecting member 11, a second connecting member 12 and a rotating shaft 13. The side plate 2 is provided with a countersunk hole for installing a locking screw, the middle of the side plate 2 is connected to the support flange 21, and the side plate 2 is provided with a hole hinged to the first connecting member 11 or the second connecting member 12. The support flange 21 is used as a connecting plate between the side plate 2 and the bearing support 31, and the support flange 21 is fixed to the side plate 2 by bolts, and the bearing support 31 directly passes through the support flange 21.

[0091] The first connecting member 11 and the second connecting member 12 are hinged to each other, and are hinged to the milling machine body 3 and the side panel 2, respectively. The rotating shaft 13, as the rotation center, can be the hinge axis between the first connecting member 11 and the second connecting member 12. Of course, the hinge axis between the first connecting member 11 and the side panel 2, or between the second connecting member 12 and the milling machine body 3 can also be in the form of the rotating shaft 13. The entire opening structure 1 has a simple structure, convenient processing, and low cost. At the same time, through the hinged structure, the side panel 2 can be translated first and then flipped relative to the milling machine body 3. When replacing the milling drum, the side panel 2 can be opened faster for replacement, thereby improving work efficiency.

[0092] In summary, the opening structure 1, side panel 2, and milling machine provided in the present application adopt a combined structure that enables the side panel 2 to first translate and then rotate, and during the opening process of the side panel 2, the support flange 21 and the bearing support 31 are separated, thereby reducing interference during opening and closing. The structure is simple and easy to operate, and at the same time, no major modification to the structure of the milling machine is required, and the cost is low. Compared with the related technology, when replacing the milling drum, there is no need to remove the side panel 2 as a whole, which saves time and effort.
