具体实施方式detailed description
下面结合附图及实施例对本发明作进一步说明：The present invention will be further described below in conjunction with the accompanying drawings and embodiments:
实施例1，如图1所示，本发明高频振动纵向铣挖头包括纵向铣挖头2、铣挖头座12、铣挖机体10、切削马达4、变速箱3，铣挖头座12安装在铣挖机体10的一端，铣挖机体10的另一端设有连接座7，连接座7可与挖掘机挖斗销相联接。切削马达4和变速箱3安装在铣挖头座12上，纵向铣挖头2上设有铣挖截齿1，纵向铣挖头2的顶部转轴安装在铣挖头座12上并与变速箱3输出端联接，变速箱3的输入端与切削马达4联接；铣挖头座12的上方固定 安装有振动箱体5，振动箱体5置于铣挖机体10内，振动箱体5和铣挖头座12与铣挖机体10侧壁通过减振橡胶9连接并实现滑动位移，振动箱体5与铣挖机体10顶部之间设有空气弹簧8。所述的振动箱体5可以采用现有技术的振动箱体5。 Embodiment 1, as shown in FIG. 1, the high-frequency vibration longitudinal milling head of the present invention comprises a longitudinal milling head 2, a milling head holder 12, a milling body 10, a cutting motor 4, a gearbox 3, and a milling head holder 12. Mounted at one end of the milling body 10, the other end of the milling body 10 is provided with a connecting seat 7, which can be coupled with the excavator bucket pin. The cutting motor 4 and the gearbox 3 are mounted on the milling head block 12, and the longitudinal milling head 2 is provided with a milling pick 1 on which the top rotating shaft of the longitudinal milling head 2 is mounted and coupled to the gearbox 3 output end connection, the input end of the gearbox 3 is coupled with the cutting motor 4; the upper part of the milling head block 12 is fixed The vibration box body 5 is installed, and the vibration box body 5 is placed in the milling machine body 10. The vibration box body 5 and the milling head block 12 are connected with the side wall of the milling machine body 10 through the vibration damping rubber 9 to realize sliding displacement, and the vibration box body An air spring 8 is provided between the top of the milling body 10 and the top of the milling body 10. The vibration box body 5 can be a vibration box 5 of the prior art.
本实施例的振动箱体5具有一对偏心轮11，偏心轮11的转轴上分别安装有完全一样的啮合齿轮，其中一个偏心轮11的转轴通过振动马达6驱动其旋转，再通过啮合齿轮使一对偏心轮11作相对运动，使振动箱体5对铣挖头座12输出高频振动力，从而实现纵向铣挖头2在做自身旋转运动的同时还能实现高速反复振动运动。The vibrating case 5 of the present embodiment has a pair of eccentric wheels 11 on which the exact same meshing gears are respectively mounted on the rotating shaft of the eccentric wheel 11, wherein the rotating shaft of one of the eccentric wheels 11 is driven to rotate by the vibration motor 6, and then the meshing gear is used to The pair of eccentric wheels 11 are relatively moved, so that the vibration box body 5 outputs a high-frequency vibration force to the milling head block 12, thereby realizing the high-speed repeated vibration movement of the longitudinal milling head 2 while performing its own rotation motion.
工作时，开启切削马达4，切削马达4经过变速箱3驱动纵向铣挖头2旋转。再开启振动马达6，振动马达6驱动偏心轮11的转轴旋转，两条转轴通过完全一样的啮合齿轮形成相对同相旋转，带动两个完全一样的偏心轮11同相旋转运动，使振动箱体5在水平方向的偏心力瓦相抵消，在垂直方向偏心力互相叠加，从而对铣挖头座12输出垂直方向的反复振动力，使铣挖头座12带着纵向铣挖头2做高频反复运动，在振动箱体5带着铣挖头座12作高速反复运动时，顶部设有空气弹簧8，限制其往上运动位置，同时空气弹簧8可以储存振动销体向上的振动力和被切物料对纵向铣挖头2的反弹力，在下行运动时释放出来，使铣挖截齿1对物料的冲击力更强。同时，机体也可通过空气弹簧对铣挖头施加压力，使切削力更大。减振橡胶9可使铣挖头座上的振动力不直接传递到铣挖机体之上。In operation, the cutting motor 4 is turned on, and the cutting motor 4 drives the longitudinal milling head 2 to rotate through the gearbox 3. The vibration motor 6 is further turned on, and the vibration motor 6 drives the rotation of the rotating shaft of the eccentric wheel 11. The two rotating shafts are rotated in the same phase by the same meshing gears, and the two identical eccentric wheels 11 are rotated in the same phase, so that the vibration box body 5 is The horizontal eccentric force is offset, and the eccentric forces are superimposed on each other in the vertical direction, thereby outputting the repeated vibration force in the vertical direction to the milling head 12, so that the milling head 12 carries the longitudinal milling head 2 to perform high frequency repetitive motion. When the vibration box body 5 carries the milling head block 12 for high-speed repeated movement, the top is provided with an air spring 8 to restrict the upward movement position, and the air spring 8 can store the vibration force of the vibration pin body and the material to be cut. The repulsive force of the longitudinal milling head 2 is released during the downward movement, so that the impact of the milling cutter 1 on the material is stronger. At the same time, the body can also apply pressure to the milling head through the air spring to make the cutting force larger. The damping rubber 9 allows the vibration force on the milling head to not be transmitted directly to the milling body.
实施例2，如图2所示，本实例的高频振动纵向铣挖头的结构与实施例1基本相同，只是采用的振动箱体5为直列四偏心轮振动箱体(其结构为现有技 术，可参见中国专利申请号；2013103465294，发明名称为直列式偏心轮振动机构)，该振动箱体可获得更大的振动冲击力。铣挖头座12与铣挖机体10之间可以不设置减振橡胶。 Embodiment 2, as shown in FIG. 2, the structure of the high-frequency vibration longitudinal milling head of the present example is basically the same as that of Embodiment 1, except that the vibration box 5 used is an in-line four-eccentric vibration box (the structure is existing) Technology For the technique, see Chinese Patent Application No. 2013103465294, the invention name is an in-line eccentric vibration mechanism, and the vibration box can obtain greater vibration impact force. No damping rubber may be provided between the milling head block 12 and the milling body 10.
实施例3，如图2所示，本实例的高频振动纵向铣挖头可应用于一些特殊场合，其结构与实施例1基本相同，只是采用的振动箱体安装在铣挖头座12的侧边，振动箱体采用集成有单偏心轮或偏心块的单偏心轮振动箱15，铣挖头座12与铣挖机体10侧壁之间设有减振橡胶9，铣挖头座12与铣挖机体10顶部之间设有空气弹簧8。振动马达6驱动单偏心轮振动箱15，在旋转运动时使偏心振动力呈圆周状，从而带动铣挖头2呈圆周状甩动，不像前文所述为直线反复振动力，这些都可实现铣挖截齿1对物料同时进行切削和冲击作用，因此也应在本发明保护范围之中。 Embodiment 3, as shown in FIG. 2, the high-frequency vibration longitudinal milling head of the present example can be applied to some special occasions, and the structure thereof is basically the same as that of Embodiment 1, except that the vibration box body used is installed on the milling head block 12. On the side, the vibration box body adopts a single eccentric vibration box 15 integrated with a single eccentric wheel or an eccentric block, and a damping rubber 9 is arranged between the milling head seat 12 and the side wall of the milling machine body 10, and the milling head seat 12 is An air spring 8 is disposed between the tops of the milling body 10. The vibration motor 6 drives the single eccentric vibration box 15, and the eccentric vibration force is circumferentially shaped during the rotary motion, thereby causing the milling head 2 to be circumferentially swayed, unlike the above-mentioned linear repeated vibration force, which can be realized. The milling cutter 1 simultaneously cuts and impacts the material and should therefore also be within the scope of the invention.
如图4所示，铣挖机或掘进机可以利用本发明高频振动纵向铣挖头。本发明铣挖机是与挖掘机配套使用的附属机具，其结构是：将实例1的高频振动纵向铣挖头通过连接座7与掘进大臂23的一端连接，掘进大臂2为伸缩结构，掘进大臂23的另一端与安装基座27铰接，安装基座27固定在挖掘机上，掘进大臂23的侧边及下边分别安装有伸缩油缸22和举升油缸25，伸缩油缸22和举升油缸25的一端与安装基座27铰接，另一端与掘进大臂23铰接。所述的高频振动纵向铣挖头采用实施例2的高频振动纵向铣挖头。As shown in Fig. 4, the milling machine or the roadheader can utilize the high frequency vibration longitudinal milling head of the present invention. The milling machine of the invention is an auxiliary machine used in combination with the excavator, and the structure thereof is: the high-frequency vibration longitudinal milling head of the example 1 is connected to one end of the excavating arm 23 through the connecting seat 7, and the digging arm 2 is a telescopic structure.

The hydraulic oil pipe is connected to the oil pipe of the driving device of the present invention. After the connection is completed, the body 10 can be placed in a position where the milling operation is required by operating the size arm of the excavator.
在铣挖头2的旋转速度和振动频率调节到合适值之后，通过控制掘进大臂23，使铣挖头2接触需要铣挖物体，铣挖截齿1对物体施加切削力的同时，还施加振动冲击力，从而使物料瞬间被击碎，被击碎的物料经过铣挖头2的旋转运动被带出，离开原来位置，避免二次磨损铣挖截齿1。After the rotational speed and the vibration frequency of the milling head 2 are adjusted to appropriate values, by controlling the tunneling arm 23, the milling head 2 is brought into contact with the object to be milled, and the milling cutter 1 applies a cutting force to the object while also applying The vibration impact force causes the material to be crushed instantaneously, and the crushed material is taken out by the rotary motion of the milling head 2, leaving the original position, and avoiding secondary wear and milling of the pick 1 .
继续操作挖掘机的的大小臂，使铣挖头2移动位置接触需要铣挖物体，从而形成连续铣挖作业。Continue to operate the size arm of the excavator so that the moving position of the milling head 2 contacts the object to be milled, thereby forming a continuous milling operation.

Fixed to the excavator, a telescopic cylinder 22 and a lifting cylinder 25 are respectively mounted on the side and the lower side of the excavating boom 23, and one end of the telescopic cylinder 22 and the lifting cylinder 25 are hinged to the mounting base 27, and the other end is connected to the excavating boom 23 Hinged; the mounting base 27 is mounted at one end of the boring machine chassis 21, and a side swaying mechanism 34 is mounted between the mounting base 27 and the boring machine chassis 21, and the mounting base 27 is controlled by the side swaying mechanism 34 to swing left and right, so that the boring is large The arm 23 performs a lateral swing at a certain angle.

本发明采用的掘进机底盘21与现有掘进机底盘相同，由底盘中发动机或电机驱动液压泵提供动力源，通过举升油缸25可使掘进大臂23上下移动。铣挖机体10安装在掘进大臂23前端，在掘进大臂23上设有伸缩油缸22，可以使铣挖机体10做一定的伸缩运动。 The roadhead chassis 21 used in the present invention is the same as the conventional roadheader chassis. The power source is driven by an engine or a motor-driven hydraulic pump in the chassis, and the jacking arm 23 can be moved up and down by the lift cylinder 25. The milling body 10 is mounted on the front end of the boring boom 23, and the telescopic cylinder 22 is disposed on the boring boom 23, so that the milling body 10 can perform a certain telescopic movement.
