Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, specifically to a milling machine tool magazine assembly and a milling machine. Background Technology

[0002] Currently, milling machines are mainly used in the renovation or construction of highways and urban roads. Milling machines are suitable for removing abandoned and damaged road markings, cement slurry, roughening, ice and snow, and hard slag left over from construction on cement or asphalt roads, parking lots, running tracks, and other road surfaces.

[0003] When a milling machine performs a cleaning operation, it primarily utilizes high-speed rotating milling blades to repeatedly impact and break up the material being removed. Because the milling blades of existing milling machines are rigidly connected to the machine frame, the impact force received by the machine frame when the blades impact the material is significant. This makes the milling machine difficult to operate and poses certain safety risks. Furthermore, when the milling blades impact the road surface, the lack of reverse cushioning means that the blades can also impact the internal structure of the road surface, potentially damaging the road or bridge's internal structure and affecting its service life. Utility Model Content

[0004] The purpose of this utility model is to provide a milling machine tool magazine assembly and a milling machine. After the milling blade contacts the road surface, it can bounce upwards in the opposite direction due to the obstruction of the road surface. During the upward bounce, its own weight can reduce its upward recoil force. At the same time, after the first support shaft is subjected to the recoil force of the milling blade, it can also further buffer the recoil force through elastic deformation. Therefore, by utilizing the recoil force buffering effect of the milling blade and the first support shaft, the recoil force received by the entire machine support can be greatly reduced, thereby making it easier for the operator to drive the milling machine and improving the safety of the milling machine. Furthermore, after the milling blade contacts the road surface, it immediately rebounds, so its vertical impact on the road surface is relatively light, which helps to reduce the degree of damage to the internal structure of the road surface.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a tool magazine assembly for a milling machine and a milling machine, including a tool magazine bracket, a tool magazine, and a rotating support assembly. The rotating support assembly is used to support the free rotation of the tool magazine bracket. The tool magazine includes four sets of tool assemblies. The four sets of tool assemblies are distributed around the rotation center axis of the tool magazine bracket in the circumferential direction. Each set of tool assemblies includes a first support shaft and milling inserts. The first support shafts are distributed along the axial direction of the rotation center axis of the tool magazine bracket. A plurality of milling inserts are sleeved on the corresponding first support shafts. The diameter of the central hole of the milling insert is larger than the diameter of the first support shaft.

[0006] Preferably, the tool magazine bracket includes a first circular plate and a central sleeve, with two first circular plates fixedly disposed at both ends of the central sleeve, and both ends of the first support shaft respectively disposed on the corresponding first circular plates.

[0007] Furthermore, two semi-circular support plates are fixedly installed in the middle region of the central sleeve. The two semi-circular support plates are arranged in an adjacent, staggered left-right distribution along the axial direction of the central sleeve, and in a front-back distribution along the radial direction of the central sleeve. A first through hole is provided on the semi-circular support plate for the first support shaft to pass through. Each pair of first support shafts passes through one corresponding semi-circular support plate. The diameter of the first through hole is smaller than the diameter of the central hole of the milling cutter and larger than the diameter of the first support shaft.

[0008] Furthermore, a spacer is provided between the milling cutter and the adjacent first circular plate, between the milling cutter and the adjacent semi-circular support plate, and between two adjacent milling cutters.

[0009] Furthermore, the rotating support assembly includes a T-shaped rotating support seat and a rotating support shaft. The T-shaped rotating support seat is fixedly disposed on the left side of one of the first circular plates and is coaxially distributed with the central sleeve. The rotating support shaft is sleeved inside the central sleeve, and one end of the rotating support shaft is threadedly connected to the inside of the T-shaped rotating support seat.

[0010] A milling machine includes the milling machine tool magazine assembly described above. The milling machine also includes a gasoline engine, a machine frame, a protective cover, and a control assembly. The gasoline engine is located on the upper part of the machine frame, and the protective cover is located on the lower part of the machine frame. The milling machine tool magazine assembly is located inside the protective cover. The outer ends of the T-shaped rotating support and the rotating support shaft are rotatably connected to the side wall of the protective cover. The gasoline engine provides rotational power to the T-shaped rotating support via belt drive. Two first traveling wheels are located inside the protective cover in front of the milling machine tool magazine assembly. The control assembly includes a fixed base, an adjusting support, a control handle, and a swing adjustment mechanism. The fixed base is fixedly located at the rear of the protective cover. The adjusting support is hinged to the fixed base. Two second traveling wheels are located at the rear of the adjusting support. The lower end of the control handle is fixedly located on the upper part of the fixed base. The swing adjustment mechanism is used to limit the upward swing of the adjusting support.

[0011] Furthermore, the swing adjustment mechanism includes an adjustment handwheel, a pull tube, a steel wire rope, a support tube, and a guide wheel. The support tube is fixedly mounted on the operating handle. The adjustment handwheel is rotatably mounted on the upper part of the support tube and can only rotate on the support tube, not move up and down. The adjustment threaded rod at the lower part of the adjustment handwheel is threadedly connected to the upper part of the pull tube. The guide wheel is rotatably mounted on the fixed seat and located below the support tube. An upper connecting rod and a lower threaded rod are fixedly mounted on the upper and lower parts of the steel wire rope, respectively. The upper connecting rod is connected to the lower part of the pull tube by a pin. The lower threaded rod is connected to the adjustment support seat. The steel wire rope is wound around the front side of the guide wheel. By pulling the steel wire rope upward, the adjustment support seat can be swung downward for adjustment.

[0012] Furthermore, an elongated hole is provided on the support tube, located on the outside of the pull tube, and three threaded holes corresponding to the elongated hole are provided on the pull tube. A limiting screw is provided on one of the threaded holes, and the nut of the limiting screw is located inside the elongated hole.

[0013] Furthermore, an upper swing limit rod and a lower swing limit rod are provided on the fixed base.

[0014] Furthermore, a dust pipe is provided on the upper rear side of the protective cover.

[0015] The beneficial effects of this utility model are: This utility model enables miniaturized manufacturing, allowing for the removal of debris in relatively confined operating spaces; due to the buffer gap between the milling cutter and the first support shaft, after the milling cutter contacts the road surface, it can bounce upwards under the obstruction of the road surface. During this upward bounce, its own weight reduces the upward recoil force. Simultaneously, there is also a buffer gap between the first support shaft and the semi-circular support plate. After the first support shaft is subjected to the recoil force of the milling cutter, it shifts through elastic deformation, further improving the... The machine incorporates a buffer to absorb recoil force. By utilizing the recoil force buffering effect of the milling cutter and the first support shaft, the recoil force received by the entire machine support can be greatly reduced, making it easier for operators to drive the milling machine and thus improving its operational safety. Furthermore, after the milling cutter contacts the road surface, it immediately rebounds upwards, resulting in a lighter vertical impact on the road surface and reducing damage to the internal structure of the road surface. By using a steel wire rope to adjust the upward swing limit of the adjustable support seat, the milling depth can be flexibly adjusted and controlled, enabling the milling machine to adapt to the cleaning work of materials within a certain thickness range.

Detailed Implementation

[0018] The following will describe specific embodiments and appendices. Figure 1-12 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] This utility model provides a tool magazine assembly 1 for a milling machine (such as...). Figure 3 and 4 As shown, the tool magazine includes a tool magazine bracket 11, a tool magazine 12, and a rotating support assembly. The rotating support assembly supports the tool magazine bracket 11 for free rotation. The tool magazine bracket 11 provides fixed support for the tool magazine 12. The tool magazine 12 includes four sets of tool assemblies 121, which are distributed circumferentially around the rotation center axis of the tool magazine bracket 11. Each set of tool assemblies 121 includes a first support shaft 1211 and a milling insert 1212. The first support shaft 1211 is axially aligned with the rotation center axis of the tool magazine bracket 11. The milling cutters 1212 are arranged in a directional distribution and are sleeved on the corresponding first support shafts 1211. In actual application, the rotating tool magazine bracket 11 drives the four sets of tool assemblies 121 to rotate, thereby enabling the milling cutters 1212 to continuously and frequently impact and break up the abandoned road markings, thus achieving the removal of the abandoned road markings. The diameter of the central hole of the milling cutter 1212 is larger than the diameter of the first support shaft 1211. Utilizing the diametrical gap between the milling cutter 1212 and the first support shaft 1211, the milling cutter 1212... 2. After contacting the ground, the milling cutter 1212 can bounce upwards due to the ground's obstruction. During this upward bounce, the milling cutter 1212 can reduce its upward recoil force using its own weight. The reduced recoil force of the milling cutter 1212 helps to reduce its impact force on the first support shaft 1211, thereby improving the ease of operation of the milling machine and enhancing its safety in practical applications. In this specific embodiment, the diameter of the first support shaft 1211 can be set to 10mm, and the diameter of the center hole of the milling cutter 1212 can be... With a clearance of 16mm, when the milling cutter 1212 is rotated around the rotation center axis of the tool magazine bracket 11 using the first support shaft 1211, the maximum gap between the side wall of the center hole of the milling cutter 1212 and the side wall of the first support shaft 1211 can be 6mm. When the milling cutter 1212 contacts the ground, the maximum upward movement distance it can move is 6mm. During the 6mm movement, the gravity of the milling cutter 1212 is used to offset part of the recoil force, thereby reducing the upward recoil force of the milling cutter 1212.

[0020] Based on the above embodiments, the specific implementation of the tool magazine bracket 11 is as follows: The tool magazine bracket 11 includes a first circular plate 111 and a central sleeve 112. Two first circular plates 111 are fixedly disposed at both ends of the central sleeve 112. The two first circular plates 111 can be directly fixedly disposed at the ends of the central sleeve 112 by welding. The two ends of the first support shaft 1211 are respectively disposed on the corresponding first circular plate 111. Specifically, a countersunk hole corresponding to the first support shaft 1211 is provided on one of the first circular plates 111, and a through hole corresponding to the first support shaft 1211 is provided on the other first circular plate 111. One end of the first support shaft 1211 is inserted into the corresponding countersunk hole, and the other end is sleeved in the corresponding through hole. Then, a pressure plate is fixedly disposed on the outside of the first circular plate 111 with the through hole. The pressure plate is used to limit the axial movement of each first support shaft 1211, thereby realizing the fixed installation of each first support shaft 1211.

[0021] Based on the above embodiments, to improve the support stability of each first support shaft 1211 for the milling cutter 1212 and ensure the accuracy of the milling depth, two semi-circular support plates 122 are fixedly installed in the middle region of the central sleeve 112. The semi-circular support plates 122 are fixedly connected to the central sleeve 112 by welding. The two semi-circular support plates 122 are arranged in an adjacent left-right staggered manner along the axial direction of the central sleeve 112, and in a front-back arrangement in the radial direction of the central sleeve 112. Through the above-mentioned arrangement of the two semi-circular support plates 122, the tool magazine 12 can ensure that there are no missed areas in the lateral range during the clearing of the markings, thereby ensuring the clearing effect. A first through hole for the first support shaft 1211 to pass through is provided on the semi-circular support plate 122, and every two first support shafts 1211 pass through... A corresponding semi-circular support plate 122 is inserted to support the central area of ​​the first support shaft 1211, thereby improving the stability of the first support shaft 1211 and its support stability for the milling cutter 1212. The diameter of the first through hole is smaller than the diameter of the central hole of the milling cutter 1212 but larger than the diameter of the first support shaft 1211. The gap between the first through hole and the first support shaft 1211 allows the first support shaft 1211 to have a certain elastic deformation and movement capability after being impacted by the milling cutter 1212. This reduces the degree of impact of the first support shaft 1211 on the first circular plate 111, thus helping to reduce the recoil force of the milling machine during operation. In practical applications, the diameter of the first through hole can be set to 11mm, so that the maximum gap between the first support shaft 1211 and the first through hole is 1mm.

[0022] Based on the above embodiments, in order to facilitate the axial movement limit of the milling blade 1212, a spacer 14 is provided between the milling blade 1212 and the adjacent first circular plate 111, between the milling blade 1212 and the adjacent semi-circular support plate 122, and between two adjacent milling blades 1212.

[0023] Based on the above embodiments, the specific implementation of the rotating support assembly is as follows: The rotating support assembly includes a T-shaped rotating support seat 131 and a rotating support shaft 132. The T-shaped rotating support seat 131 is fixedly disposed on the left side of one of the first circular plates 111, and the T-shaped rotating support seat 131 is coaxially distributed with the central sleeve 112. The T-shaped rotating support seat 131 can be directly fixed to the corresponding first circular plate 111 by bolts. The rotating support shaft 132 is sleeved inside the central sleeve 112, and one end of the rotating support shaft 132 is threadedly connected to the inside of the T-shaped rotating support seat 131. Specifically, an external thread is provided at one end of the rotating support shaft 132, and an internal thread is provided inside the T-shaped rotating support seat 131. After one end of the rotating support shaft 132 extends into the inside of the T-shaped rotating support seat 131, it is rotated and tightened, thereby realizing the fixed connection between the rotating support shaft 132 and the T-shaped rotating support seat 131. In practical applications, the outer ends of the T-shaped rotating support 131 and the outer ends of the rotating support shaft 132 are rotatably mounted on the corresponding brackets, thereby enabling them to provide rotational support for the tool magazine 12.

[0024] This utility model provides a milling machine (such as...) Figure 1 , Figure 2As shown, the milling machine includes the tool magazine assembly 1 described above. The milling machine also includes a gasoline engine 2, a machine support frame 3, a protective cover 4, and a control assembly. The gasoline engine 2 is located on the upper part of the machine support frame 3. The gasoline engine 2 is a known mature product in the prior art, therefore its specific structure and working principle will not be described in detail. The gasoline engine 2 is directly fixed to the machine support frame 3 with bolts. The protective cover 4 is located on the lower part of the machine support frame 3 and is fixed to the lower part of the machine support frame 3 by bolt connections. Shock-absorbing columns are provided between the protective cover 4 and the machine support frame 3. The milling machine tool magazine assembly 1 is located inside the protective cover 4. The T-shaped rotating support 1... The outer ends of the T-shaped rotating support 131 and the outer ends of the rotating support shaft 132 are rotatably connected to the side wall of the protective cover 4. The support of the protective cover 4 ensures stable rotation of the milling machine tool magazine assembly 1. The gasoline engine 2 provides rotational power to the T-shaped rotating support 131 via belt drive. Specifically, a first pulley is fixedly installed at the outer end of the T-shaped rotating support 131, and a second pulley is installed on the output shaft of the gasoline engine. A transmission belt is sleeved between the first and second pulleys. When the gasoline engine 2 starts rotating, the transmission belt drives the T-shaped rotating support 131 to rotate, thereby enabling the four sets of tool assemblies 121 to rotate around the rotating support shaft 132. The interior of the cover 4 is equipped with two first traveling wheels 41 located in front of the milling machine tool magazine assembly 1. A partition 42 is provided between the two first traveling wheels 41 and the milling machine tool magazine assembly 1. The control assembly includes a fixed base 51, an adjusting support base 52, a control handle 53, and a swing adjustment mechanism. The fixed base 51 is fixedly installed at the rear of the protective cover 4. The adjusting support base 52 is hinged to the fixed base 51. Specifically, a hinge shaft is provided on the fixed base 51. Two hinge lugs 522 on the adjusting support base 52 are rotatably mounted on the hinge shaft. The adjusting support base 52 can rotate around the hinge shaft. To limit the rotation range of the adjusting support base 52, an upper... The upper swing limit rod 511 and the lower swing limit rod 512 are located above and below the hinge shaft, respectively. The upper swing limit rod 511 is used to limit the adjusting support seat 52 from swinging upward, and the lower swing limit rod 512 is used to limit the adjusting support seat 52 from swinging downward. Two second traveling wheels 521 are provided at the rear of the adjusting support seat 52. In actual application, the milling machine can move smoothly on the ground by using the support of the first traveling wheel 41 and the second traveling wheel 521. The lower end of the control handle 53 is fixedly set on the upper part of the fixed seat 51. The swing adjustment mechanism is used to limit the upward swing of the adjusting support seat 52.

[0025] The specific implementation of the swing adjustment mechanism is as follows: The swing adjustment mechanism includes an adjusting handwheel 541, a pull tube 542, a steel wire rope 543, a support tube 544, and a guide wheel 545. The support tube 544 is fixedly mounted on the operating handle 53. The adjusting handwheel 541 is rotatably mounted on the upper part of the support tube 544 and can only rotate on the support tube 544, not move up and down. The adjusting threaded rod 5411 at the lower part of the adjusting handwheel 541 is threadedly connected to the upper part of the pull tube 542. The guide wheel 545 is rotatably mounted on the fixed seat 51 and located below the support tube 544. An upper connecting rod 5431 and a lower threaded rod 5432 are fixedly mounted on the upper and lower parts of the steel wire rope 543, respectively. The upper connecting rod 5431 is connected to the lower part of the pull tube 542 by a pin. Specifically, on the pull tube... A through hole is provided at the lower part of 542, and a through hole is also provided at the upper part of the upper connecting rod 5431. After the upper connecting rod 5431 is sleeved inside the lower part of the pull tube 542, a pin is used to connect the pull tube 542 and the upper connecting rod 5431 through the two through holes. The lower threaded rod 5432 is connected to the adjusting support seat 52. Specifically, the rear end of the lower threaded rod 5432 passes through a through hole provided on the rear part of the adjusting support seat 52. Then, a nut is sleeved on the rear end of the lower threaded rod 5432. The nut's limiting action prevents the lower threaded rod 5432 from detaching from the adjusting support seat 52. At the same time, the tension of the wire rope 543 can be adjusted by rotating the nut. The wire rope 543 is wound around the front side of the guide wheel 545. By pulling the wire rope 543 upward, the adjusting support seat 52 can be adjusted downward. When the adjusting handwheel 541 is turned to move the pull tube 542 upward, the pull tube 542 pulls the adjusting support seat 52 downward at a certain angle through the steel wire rope 543. Since the second traveling wheel 521 is in contact with the ground and cannot swing downward, the downward movement of the adjusting support seat 52 actually increases the rear height of the protective cover 4, thereby achieving a reduction in the milling depth. When the adjusting handwheel 541 is turned to move the pull tube 542 downward, the pull tube 542 releases the adjusting support seat 52 through the steel wire rope 543. Releasing the adjusting support seat 52 lowers the rear height of the protective cover 4, thereby achieving a change in the milling depth.

[0026] During the reciprocating movement of the pull tube 542 by adjusting the rotation of the threaded rod 5411, to prevent the pull tube 542 from disengaging from the threaded rod 5411, an elongated hole 5441 located on the outside of the pull tube 542 is provided on the support tube 544. Three threaded holes 5421 corresponding to the elongated hole 5441 are provided on the pull tube 542. A limiting screw 5422 is provided on one of the threaded holes 5421. In actual application, the positions of the three threaded holes 5421 on the pull tube 52 are determined according to actual needs. At the same time, which threaded hole 5421 is used to install the limiting screw 5422 is also determined according to actual needs. The nut of the limiting screw 5422 is located inside the elongated hole 5441. By using the elongated hole 5441 to limit the movement of the limiting screw 5422, the movement of the pull tube 52 is limited, thereby effectively preventing the pull tube 52 from disengaging from the threaded rod 5411.

[0027] When milling the road surface using the high-speed rotating milling cutter 1212, a large amount of dust will be stirred up inside the protective cover 4. To facilitate the collection of this dust, a dust exhaust pipe 43 is installed on the upper rear side of the protective cover 4. The dust exhaust pipe 43 is connected to a vacuum cleaner via a flexible hose. When the vacuum cleaner is turned on, the stirred-up dust can be collected. To improve the service life of the milling cutter 1212, a carbide tip can be added to the cutting head of the milling cutter 1212.

[0028] In practical applications, to further improve the safety of milling machine operation, an ignition switch 531 is installed on the control handle 53 near the handle. The ignition switch 531 can be used to control the gasoline engine 2 to shut down. In case of emergency during milling, the ignition switch 531 can be used to immediately shut down the gasoline engine 2.

[0029] In this utility model, "left" and "right" are relative positions used for the convenience of describing positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.

[0030] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

However, the present invention is not limited to the above embodiments and examples. For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
