Definitions
- the invention relates to a driver primarily for driving a post into the ground.
- the driver can be more compact than known types of post drivers making it much easier to use in confined spaces.
- the operating means is arranged to apply repeated back and forth movements to the hammer following an initial striking load applied by the hammer.
- the resilient means comprises a pair of springs within a housing one of which springs may compress as the hammer is urged in a striking direction and the other of which springs may compress as the operating means urges the hammer in the opposite direction.
- the said springs may be coil springs preferably arranged substantially coaxially within the housing. Adjacent ends of the springs may be separated by a member through which the hammer can be moved by the operating means.
- the resilient means may comprise rubber springs.
- the operating means preferably includes an arm which may be arranged to move the hammer along the guide.
- the arm is preferably pivotally connected to a mounting.
- the arm may also be pivotally connected to the hammer.
- the aforesaid operating means may take the form of an actuator which is preferably fluid operable.
- the actuator preferably acts on the arm to move the arm about its pivotal connection to the mounting.
- the actuator preferably acts on the arm at a point closer to the pivot which connects the arm to the mounting than to the point at which the arm is pivotally connected to the hammer. In that way, a short stroke of the actuator will provide a relatively large movement of the pivotal connection to the hammer. Therefore, the actuator can be fairly fast acting bearing in mind that a small stroke is all that is needed to move the hammer as required.
- the operating means is preferably fluid operable and means may be provided in a fluid circuit for the operating means for reversing the operation of the operating means after the given parameter has been sensed.
- the means for reversing the operating means may be valve arranged to reverse fluid flow to the operating means on sensing the said parameter.
- the guide is upstanding and the operating means arranged to move the hammer up and down on the guide.
- the guide may be adjusted in an up-and-down direction.
- Holding means such as a removable pin may be provided for holding the carrier in its adjusted position.
- the aforesaid mounting for arm is preferable on or part of the carrier.
- An impact receiver such as a cap or cap-like member may be provided for location 75 on the top of a member such as a post to be driven by the hammer and to which the striking load is applied by the hammer.
- the actuator for adjusting the position of the carrier may be arranged to apply a load on the impact receiving member during operation of the hammer.
- Mounting means may be provided for mounting the driver on a host vehicle such as a tractor.
- the host vehicle may be a front end loader or a host machine with an hydraulic arm for example a JCB or a three hundred and sixty degrees machine.
- the driver has ground engageable legs.
- Figure 2 is a front view of the post driver of Figure 1 in the direction of arrow 95 II in Figure 1 ;
- Figure 7 is a perspective diagrammatic view of a preferred form of post driver in accordance with the invention.
- cap 22 is generally rectangular and is shown in cross-section in Figures 2 to 5.
- Cap 22 has metal side plates 28 which receive between them a rigid metal top plate 30.
- a dished metal plate 32 is mounted within the cap 22 immediately beneath the top plate 30.
- the cap 22 locates on the upper end of a post 34, the dished plate 32
- the arm 48 is pivotally connected close to the pivots 52 and between its ends to a push rod 60 of a hydraulic actuator 62.
- the weight of the post driver is primarily carried by the arms 40 and the arms 40 are lowered so as to position the cap as shown in Figures 3 to 5 with at least some of the weight of the post driver and the arms 40 being carried by the post 34. In that way, the cap 22 will remain in position on the post 34 during the hammer action of the post driver described below.
- the actuator 104 has a push rod 106 which is secured by an attachment (not shown) to the inside of the mast 10. Extension and retraction of the actuator 104 raises and lowers the mast 10, a slightly raised position of the mast 10 being shown in broken lines in Figure 7.
- the mast 10 carries two spaced- apart mounting plates
- the legs 98 are adjusted so as to contact the ground. In that way, the vehicle 124 does not need to support the weight of the post driver.
- the pin 120 is removed and fluid under reduced pressure is fed to the chamber 132 of the actuator 104 so that the actuator 104 draws the mast 10 downwardly. Such downward movement continues until the stop 81 (the stop 26
