The mounting frame 131 is further provided with a driving oil cylinder 132, one end of the driving oil cylinder 132 is hinged to the upper end of the hammer rod 133, and the other end of the driving oil cylinder 132 is hinged to the mounting frame 131. The driving cylinder 132 can drive the hammer lever 133 to move up and down, and when the hammer lever 133 moves down, it can impact the crushing head 134, and at this time, the crushing head 134 can crush the rock stratum.
The crushing work machine includes a power machine 2 and the crushing unit 13, and the power machine 2 includes a power system, a hydraulic system, and a control system. The power system comprises two running components, the hydraulic system is connected with the driving oil cylinder 132 through a pipeline and used for providing hydraulic oil for the driving oil cylinder 132, and the control system is used for controlling the whole power machine 2 and the crushing component 13 to work. In this embodiment, the power machine 2 adopts a part of the excavator with the forearm removed, and in other embodiments, the power machine 2 may adopt other structures. The mounting bracket 131 of the crushing assembly 13 is arranged at the front end of the large arm.
In this embodiment, the crushing head 134 adopts a drill rod, and the mounting bracket 131 adopts a cylindrical structure; the crushing head 134 is slidably mounted at the lower end of the mounting bracket 131. The lower end of the mounting bracket 131 is further provided with a limiting pin for limiting the upper and lower movable ranges of the crushing head 134. In other embodiments, the crushing head 134 may employ a hammer head or other structure capable of crushing the formation.
The hammer rod 133 has a cylindrical rod-shaped structure, a movable block 135 is arranged at the lower end of the hammer rod 133, the movable block 135 is in spherical hinge connection with the hammer rod 133, and when the hammer rod 133 moves downwards, the hammer rod 133 can hammer the crushing head 134 through a hammering surface at the lower end of the movable block 135. Specifically, the movable block 135 includes a mounting portion 1351 and a hammering portion 1352 connected to each other, wherein the mounting portion 1351 is a hemispherical spherical convex portion; the spherical convex portion includes a spherical surface and a circular end surface, and the hammering portion 1352 is cylindrical and has a diameter smaller than that of the circular end surface. Correspondingly, a spherical groove 1331 is arranged on the end surface of the lower end of the hammer rod 133, and the radii of the spherical groove 1331 and the spherical convex part are approximately equal, so that the groove surface of the spherical groove 1331 can be well matched with the surface of the spherical convex part; the spherical protruding portion can freely swing in the spherical recess 1331.
If a certain included angle exists between the hammering surface and the upper surface of the crushing head 134, when the part of the hammering surface is firstly contacted with the upper surface of the crushing head 134, the movable block 135 is in spherical hinge connection with the hammer rod 133, and under the action of force, the movable block 135 can swing a certain angle in a self-adaptive manner until the whole hammering surface of the movable block 135 is well matched with the upper surface of the crushing head 134, so that the damage caused by the local stress of the crushing head 134 or the hammer rod 133 is avoided.
In addition, since the spherical protruding portion and the spherical groove 1331 are in spherical contact, the contact manner enables the movable block 135 to keep the whole stress surface of the spherical protruding portion and the spherical groove 1331 to be maximized within a certain swing range, and damage of the contact surface can be reduced.
Further, a circular limiting plate 1332 is arranged on the lower end face of the hammer rod 133, and the limiting plate 1332 is connected with the hammer rod 133 through a screw; the movable block 135 includes a limit portion 1353, and the limit plate 1332 can be contacted with or separated from the limit portion 1353. Specifically, the middle of the stopper plate 1332 is provided with a through hole having a diameter smaller than that of the spherical protrusion and larger than that of the hammering portion 1352. The spherical protrusion of the movable block 135 is disposed between the stopper plate 1332 and the groove surface of the spherical groove 1331, and the hammering portion 1352 of the movable block 135 passes through the through hole of the stopper plate 1332. Since the diameter of the through hole of the stopper plate 1332 is smaller than the diameter of the spherical protrusion, the stopper plate 1332 is enabled to restrict the spherical protrusion between the stopper plate 1332 and the spherical groove 1331.
When the hammering portion 1352 of the movable block 135 is separated from the upper end of the crushing head 134, the movable block 135 as a whole moves downward by the gravity, and the edge of the spherical protrusion contacts the stopper plate 1332, and at this time, the edge of the spherical protrusion corresponds to the stopper portion 1353 of the movable block 135. When the hammering portion 1352 of the movable block 135 contacts with the upper end of the crushing head 134, the spherical protrusion contacts with the spherical groove 1331, and the lower surface of the spherical protrusion is disposed in a gap with the upper surface of the stopper plate 1332, so that the stopper plate 1332 can be prevented from affecting the swing of the spherical protrusion. It should be noted that, in other embodiments, the limiting plate 1332 may not be provided, and the movable block 135 may be limited by a limiting structure in other spherical hinge assemblies.
Further, a recess is provided in the middle of the hammer 1352. As the time of use increases, the edges of the crushing head 134 are more easily damaged, and at this time, the upper surface of the crushing head 134 is easily formed with a convex structure. If the lower part of the hammering part 1352 is a circular end surface, when the hammering part 1352 contacts with the upper surface of the crushing head 134, point contact is easily formed, and the contact part is excessively stressed. Therefore, after the recess is provided in the middle of the hammering portion 1352, point contact between the hammering portion 1352 and the crushing head 134 can be prevented, and thus the service life of the crushing head 134 can be improved.
It should be noted that this embodiment is one of many embodiments, and in other embodiments, the spherical protrusion may be disposed on the hammer lever 133, and correspondingly, the spherical recess 1331 may be disposed on the movable block 135. Alternatively, the movable block 135 is ball-hinged to the upper end of the crushing head 134, and when the hammer lever 133 moves downward, the lower end of the hammer lever 133 strikes the upper end of the movable block 135. Alternatively, the hammering portion 1352 is not limited to be cylindrical, and may have other bump structures; the hammer lever 133 is not limited to a cylindrical shape, and may have other rod-like structures. Alternatively, in other embodiments, the drive ram 132 may be replaced with other telescoping power arrangements. The mounting bracket 131 is not limited to be cylindrical, and other structures may be employed as long as the crushing head 134 and the hammer lever 133 can be slidably provided on the mounting bracket 131.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and various modifications and variations may be made to the present utility model by those skilled in the art.
