This type of hand-held power pile driver has a small engine in a hand-held frame, and the impact of the hammer is applied directly to the hand, making the machine easy to shake and difficult to hold.
As a result, the hammer head easily comes off from the head of the pile, which is dangerous and difficult to work with, and in the case of wooden piles, pieces of wood from the broken pile head are scattered, which is very dangerous.

This idea was made in view of the above points,
The hammer head that strikes the pile head is wrapped in a pile guide cylinder and the pile head is driven into the cylinder to prevent the hammer head from coming off the pile head and to prevent the wood chips from flying off the pile head. The purpose of this invention is to provide a hand-held power pile driver that measures machine stability and work safety.

This machine is installed in the handheld frame 1 as shown by the dashed line in Figure 1.
Since it can be placed on the ground 24 by the lower square frame 1a,
In this state, the engine 7 is started. engine 7
When the clutch shaft 1 is started, the clutch shaft 1 rotates, and the small gear 12
The crank pin 14 rotates by being decelerated by the large gear 13, and the piston 16 moves up and down along with the striker 20 by the stove 15. Although the striker 20 is not fixed to the piston 16, it moves up and down almost equally due to the action of its negative pressure chamber 20a. At this time, since the hammer head 21 does not have a stake 25, it is positioned below and away from the tip of the cylinder 19, as shown by the two-dot chain line in FIG. 2, so that there is no blank hitting by the piston 16. Then, holding the machine in hand as shown in Fig. 3, place the pile guide tube 22 over the head of the pile 25 that has been lightly erected in advance, and place the hammer head 21 on the head of the pile 25. . Then pile 2
5 pushes up the hammer head 21, resulting in the state shown by the solid line in FIG. If the machine is placed on the head of the pile 25 by its own weight, the machine will gradually lower as the hammer head 21 drives the pile 25, and the pile driving will be completed. At this time, the striker 20 strikes the hammerhead 21 as the piston 16 descends, but since the force released from the piston 16 at the bottom dead center of the piston 16 acts on the striker 20, the hammerhead 21 is hit by the actual strike by the piston 16. The striking force is even greater than force. In this way, when you finish driving one pile, you can move it to the top of the pile that has been lightly erected next to it, and you can drive consecutive piles just by carrying this machine around.

As mentioned above, this invention provides a pile guide tube, wraps the hammerhead inside the pile guide tube, and drives the pile within the tube using the hammerhead, so that the hammerhead does not come off the pile head and is attached to the main shaft. In addition to making the machine more stable and easier to work with, the machine is also superior in terms of safety, as wood chips at the top of the pile scatter and fall within the pile guide tube, preventing them from scattering around and hitting the worker's face. Effects can be obtained.
