Tamping rammer:it is made according to the principle of two-stroke internal combustion engine, and there are two pistons in the cylinder, the upper piston is the internal combustion piston, and the lower piston is the buffer piston. The lower part of the cylinder is equipped with a rammer that slopes the bottom surface, so that the vertical axis of the cylinder is skewed forward. The upper piston rod stretches out from the through hole in the middle of the cylinder top cover, and the lower piston rod stretches out from the lower end face of the cylinder, and is integrated with the rammer, and the cylinder and the rammer are tightened by a spring, and a handrail is provided to control the forward direction of the rammer. The fire rammer is under the action of the ignition and explosion force of the combustible mixture, therefore, it jumps off the ground in front of the top and under the action of its own weight, and falls to the ground to ram the soil, and the rammer jumps and falls, and the fuselage moves forward step by step. The rammer product has a wide range of uses, not only suitable for tamping and leveling with various sand, gravel and triple soil, but also suitable for tamping and leveling asphalt gravel, concrete and clay, especially suitable for the construction of buildings, ground, courtyards, roadbeds, bridge piles, trenches, fields, narrow sites and other environments.

Five steps to solve the rusted stainless steel screws in life
Stainless steel screws are commonly used in everyday life, but over time, they can develop rust, making them difficult to remove. If you find yourself dealing with a rusted stainless steel screw, there are several effective methods you can try to loosen and remove it. Here’s a detailed guide on how to handle the situation:
1. **Shaking with a Wrench**: Instead of forcefully tightening the screw with a wrench, which could damage the corners or strip the screw, gently tap the wrench handle with a hammer. This motion helps break the bond between the screw and the surrounding material, making it easier to turn.
2. **Tapping the Nut**: Use the edge of a square-headed hammer to lightly tap the rusted nut. The tapping helps to loosen the grip between the nut and the thread. For example, when working on a bicycle pedal, adjust the force based on the thickness of the pedal and the material (metal or plastic). Be careful not to apply too much pressure on plastic parts. If this doesn’t work, try tapping the nut directly with a hammer in the direction of loosening.
3. **Heating with Fire**: For stubborn screws that won’t budge, you can use a gas welding torch. Apply an oxidizing flame to heat the nut and screw. Once hot, apply a small amount of oil to the heated area. The heat causes the metal to expand, while the oil helps it contract quickly when cooled, creating space for removal. However, be cautious if there are nearby plastic components, as excessive heat could damage them.
4. **Punching Technique**: When the top of the screw is corroded and can’t be turned with a wrench or wire cutter, start by using a flat-head screwdriver and a hammer to create a V-shaped groove on the screw head. Then, angle the tool to strike in the direction the screw needs to come out. Once loosened, you can use a wire cutter to remove the screw. This method is also useful for slotted screws that have been damaged.
5. **Welding Method**: If the screw head is broken and you can't use an electric drill (as it might damage the threads), consider welding a piece of iron onto the remaining part of the screw. The size of the iron should match the diameter of the stainless steel screw. This provides a better grip, allowing you to unscrew it more easily.
Whether you're working on a mechanical device, a bicycle, or a home repair project, these techniques can help you safely and effectively deal with rusted stainless steel screws. Always take care to avoid damaging surrounding materials, especially when using heat or force. With the right approach, even the most stubborn screws can be removed without causing further issues.
