Specifically, the first transmission rod 31 and the second transmission rod 32 may be screwed, and the second transmission rod 32 and the blade 6 may be welded or screwed.
驱动轴 1的作用在于带动凸轮 2转动， 为了保证驱动轴在转动过程中 不易发生偏移， 上述熨平板压实梁还优选包括： 轴承座 8, 其安装于熨平板 架 7, 用于穿设驱动轴 1。 The driving shaft 1 functions to drive the cam 2 to rotate. In order to ensure that the driving shaft is less likely to be displaced during the rotating process, the screed compacting beam preferably further includes: a bearing housing 8 mounted on the screed frame 7 for piercing Drive shaft 1.
熨平板压实梁的刀片 6通常较长， 其在运动过程中容易出现偏摆， 上 述限位机构的作用在于： 使传动杆 3沿垂直方向运动， 避免传动杆 3带动 刀片 6偏摆。 本实施例提供的限位机构为设有传动杆滑动轴套 401的限位 板 4, 对传动杆 3的运动起导向限位作用， 同时降低传动杆 3沿轴向运动时 的摩擦力。 优选方案， 该传动杆滑动轴套 401与传动杆 3间隙配合。 The blade 6 of the screed compacting beam is generally long, and is prone to yaw during the movement. The function of the above-mentioned limiting mechanism is to move the transmission rod 3 in the vertical direction to prevent the transmission rod 3 from displacing the blade 6. The limiting mechanism provided in this embodiment is a limiting plate 4 provided with a sliding sleeve 401 of the transmission rod, which guides the movement of the transmission rod 3 and reduces the frictional force of the transmission rod 3 when moving in the axial direction. Preferably, the transmission rod sliding sleeve 401 is in clearance fit with the transmission rod 3.
传动杆复位机构 5的作用在于： 使所述传动杆 3的上端紧压凸轮 2, 由 此使得凸起部 21转离传动杆 3时， 传动杆 3能向上运动， 实现刀片 6的向 上运动。 上述传动杆复位机构 5包括： 振动板 51、 复位弹簧 52、 复位弹簧 导向杆 53和连接杆 54。 其中， 振动板 51和连接杆 54与传动杆 3位置相对 固定， 当传动杆 3向下运动时， 连接杆 54带动振动板 51向下运动用来压 缩复位弹簧 52,使传动杆 3向下运动时复位弹簧 52保持压紧状态； 复位弹 簧 52用来提供回复力将振动板 51弹起， 使刀片 6向上运动； 复位弹簧导 向杆 53对复位弹簧 52起到导向和限位的作用。 进一步地， 为了便于安装 并提高固定强度， 复位弹簧限位部 9 包括： 螺母和垫板， 螺母螺接于复位 弹簧导向杆 53的下端， 垫板位于螺母上方。 具体的， 上述复位弹簧导向杆 53可以为螺栓， 其头部的螺母和位于螺母上方的垫板形成复位弹簧限位部 9。 传动杆复位机构 5中的第一紧固件和第二紧固件可以为本领域技术人员 熟知的部件， 具体如： 螺母、 螺栓、 铆釘等。 The function of the transmission rod resetting mechanism 5 is to press the upper end of the transmission rod 3 against the cam 2, thereby causing the transmission rod 3 to move upward when the projection portion 21 is turned away from the transmission rod 3, thereby achieving upward movement of the blade 6. The transmission rod reset mechanism 5 includes a vibration plate 51, a return spring 52, a return spring guide rod 53, and a connecting rod 54. Wherein, the vibrating plate 51 and the connecting rod 54 and the connecting rod 3 are relatively fixed in position.

In order to prevent the return spring guide rod 53 from being excessively rubbed by the guide rod through hole, the inner wall of the guide rod through hole is preferably provided with a guide rod sliding sleeve, and the guide rod sliding shaft The sleeve is clearance-fitted with the return spring guide rod 53 to reduce the friction of the guide rod 53 and prolong the service life of the return spring guide rod 53.
由上述内容可知， 本实施例提供的熨平板压实梁是利用凸轮转动过程 中： 凸起部转向传动杆→挤压传动杆→带动刀片向下运动， 和凸起部转离 传动杆→传动杆复位→带动刀片向上运动， 由此产生振动脉沖， 实现熨平 板压实梁的往复运动。 相对现有的液压驱动熨平板压实梁， 本实施例提供 的熨平板压实梁结构较为筒单， 由此一方面成本较低， 另一方面拆卸方便， 便于设备的后期维修。 It can be seen from the above that the screed compacting beam provided by the embodiment is in the process of using the cam to rotate: the bulge steering transmission rod → the squeezing transmission rod → driving the blade downward movement, and the convex portion turning away from the transmission rod → transmission The rod is reset → the blade is moved upward, thereby generating a vibration pulse to realize the reciprocating motion of the screed compacting beam. Compared with the existing hydraulically driven screed compacting beam, the screed compacting beam structure provided in this embodiment is relatively simple, so that the cost is low on the one hand, and the disassembly is convenient on the other hand, which facilitates the later maintenance of the equipment.
图 3示出了本发明实施例 2的熨平板压实梁的结构。 本实施例提供的 熨平板压实梁与实施例 1的区别在于： Fig. 3 shows the structure of a screed compacting beam of Embodiment 2 of the present invention. The difference between the screed compacting beam provided in this embodiment and the embodiment 1 is:
凸轮 2的凸起部 21个数为多个（本实施例中为 6个）， 且凸起部 21沿 凸轮 2的周向均匀分布。 The number of the projections 21 of the cam 2 is plural (six in the present embodiment), and the projections 21 are evenly distributed along the circumferential direction of the cam 2.
增加凸起部 21的优点在于： 凸轮 2转动一周， 可实现传动杆的多次挤 压复位， 带动刀片多次进行往复运动。 因此， 设有多个凸起部 21的凸轮 2 具有振动频率加速的作用， 使驱动轴较低的转速便可获得较高的振动频率， 节约能耗； 本领域技术人员还可通过调节凸轮凸起部的个数来调节熨平板 压实梁的振动频率。 The advantage of adding the raised portion 21 is that: the cam 2 is rotated one turn, and multiple press-reduction of the transmission rod can be realized, and the blade is driven to reciprocate a plurality of times. Therefore, the cam 2 provided with the plurality of bosses 21 has the function of accelerating the vibration frequency, so that a lower vibration speed of the drive shaft can obtain a higher vibration frequency, saving energy consumption; those skilled in the art can also adjust the cam convex The number of the starting parts is used to adjust the vibration frequency of the screed compacting beam.
设置凸起部 21沿凸轮 2的周向均匀分布的优点在于： 提高熨平板压实 梁振动频率的稳定性。 The advantage of providing the convex portion 21 uniformly distributed along the circumferential direction of the cam 2 is to increase the stability of the vibration frequency of the screed compacting beam.
作为优选方案， 凸轮的相邻凸起部之间通过圓弧面圓滑过渡， 用以降 低凸轮和传动杆之间的摩擦， 延长凸轮和传动杆的使用寿命。 如图 4至图 5示出了本发明实施例 3的熨平板压实梁的结构。 本实施 例提供的熨平板压实梁与实施例 2的区别在于： Preferably, the adjacent convex portions of the cam are smoothly transitioned through the circular arc surface to reduce the friction between the cam and the transmission rod, and prolong the service life of the cam and the transmission rod. The structure of the screed compacting beam of Embodiment 3 of the present invention is shown in Figs. The difference between the screed compacting beam provided in this embodiment and the second embodiment is:
传动杆 3的上端设有传动杆滚子 301 ,转动杆滚子 301与凸轮 2滚动配 合。 凸轮转动过程中， 传动杆滚子 301 也随之转动， 由此减小凸轮受到的 摩擦， 延长凸轮的使用寿命。 The upper end of the transmission rod 3 is provided with a transmission rod roller 301, and the rotation rod roller 301 is in rolling engagement with the cam 2. During the rotation of the cam, the drive rod roller 301 also rotates, thereby reducing the friction experienced by the cam and prolonging the service life of the cam.
类似的， 传动杆的上端还可设为圓弧面， 同样起到减小凸轮摩擦， 延 长设备使用寿命的效果。 Similarly, the upper end of the transmission rod can also be set as a circular arc surface, which also reduces the friction of the cam and prolongs the service life of the equipment.
需要说明的是， 上述实施例中凸轮的个数为一个， 相应的传动杆的个 数也为一个， 本领域技术人员可以理解： 为了降低每个传动杆的受力， 延 长传动杆的使用寿命， 凸轮和传动杆的个数也可以为多个， 只需保证凸轮 形状相同， 且沿转动轴轴线方向可重叠设置， 便可保证每个传动杆的运动 的振幅及频率一致， 不影响刀片的上下往复运动。 It should be noted that, in the above embodiment, the number of the cams is one, and the number of the corresponding transmission rods is also one. Those skilled in the art can understand that: in order to reduce the force of each transmission rod, the service life of the transmission rod is extended. The number of cams and transmission rods can also be multiple. It only needs to ensure that the cams have the same shape and can be overlapped along the axis of the rotating shaft to ensure the amplitude and frequency of the movement of each transmission rod are consistent, without affecting the blade. Reciprocating up and down.
需要说明的是， 上述实施例中传动杆复位机构中连接杆、 复位弹簧和 复位弹簧导向杆的个数均为两个， 为了优化传动杆的复位效果， 上述部件 的个数也大于 2。 It should be noted that, in the above embodiment, the number of the connecting rod, the return spring and the return spring guiding rod in the transmission rod resetting mechanism are both two. In order to optimize the reset effect of the transmission rod, the number of the above components is also greater than 2.
需要说明的是， 上述限位机构还可采用本领域技术人员熟知的其它形 式， 如采用限位轴、 限位块等。 上述传动杆复位机构也可采用本领域技术 人员熟知的其它形式。 It should be noted that the above-mentioned limiting mechanism may also adopt other forms well known to those skilled in the art, such as using a limiting shaft, a limiting block and the like. The above-described transmission rod reset mechanism can also take other forms well known to those skilled in the art.
