Job Details

In construction, there are three main types of compactor: the plate, the rammer, and the road roller. The roller type compactors are used for compacting crushed rock as the base layer underneath concrete or stone foundations or slabs. The plate compactor, vibrating plate, or tamper, has a large vibrating baseplate and is suited for creating a level grade, while the rammer compactor has a smaller foot. The rammer, or trench rammer, is mainly used to compact the backfill in narrow trenches for water or gas supply pipes etc. Road rollers may also have vibrating rollers. In plates and rollers the vibration is provided by rapidly rotating eccentric masses. In smaller plates the vibration causes a tendency to move forwards, while some larger plates are provided with a directional control. In the rammer the foot is mounted on a sleeve that slides vertically in the leg. Inside the sleeve, a piston is driven up and down by the engine through a reduction gear, crank and connecting rod. Substantial coil springs above and below the piston connect it to the sliding sleeve. The connection between the sleeve and foot is at small angle so that the whole rammer leans away from the operator. The vibrating motion is therefore slightly off the vertical, and this gives the rammer a tendency to 'walk' forwards. The sliding joint in the leg is protected by a flexible bellows.squeezed in. Such handguns usually had a ramming mechanism built into the frame. The user pulled a lever underneath the barrel of the pistol, which pushed a rammer into the aligned chamber.

With the development of modern mechanical processing industry, the requirements for cutting quality and accuracy are constantly improving, and the requirements for improving production efficiency, reducing production cost and having high intelligent automatic cutting function are also improving. The development of NC cutting machine must meet the requirements of the development of modern mechanical processing industry. Cutting machine is divided into flame cutting machine, plasma cutting machine, laser cutting machine, water cutting, etc. Laser cutting machine has the fastest efficiency, the highest cutting accuracy and generally small cutting thickness. The cutting speed of plasma cutting machine is also very fast, and the cutting surface has a certain slope. Flame cutting machine needle for thick carbon steel material. Cutting machines are used in metal and non-metal industries. Generally speaking, non-metal industries are divided in detail, such as stone cutting machines for cutting stone, concrete cutters, water cutting machines, sawtooth cutting machines, laser cutting machines for cutting cloth and plastic, chemical fiber products, blade cutting machines, flame cutting machines, plasma cutting machines for cutting metal materials, and NC cutting machines in flame cutting machines, And manual. Manual includes small sports car, semi-automatic, pure manual, CNC, gantry CNC cutting machine, cantilever CNC cutting machine, desktop CNC cutting machine, intersecting line CNC cutting machine, etc.

The trowel machine is also known as the light receiver. Its main structure is a trowel rotor driven by gasoline engine, and a trowel is installed on the bottom of the cross in the middle of the rotor. The tilt direction of the spatula is consistent with the rotation direction of the rotor. Road construction machinery is a kind of machinery used to build and maintain roads. It is also called "road machinery". There are mainly circuit breakers, bulldozers, scrapers, leveling machines, loaders, rollers, etc. When the pavement needs to be paved, there are pavement engineering machinery such as pavement material preparation and paving machinery, as well as auxiliary engineering machinery such as lifting, transportation and stone processing.

Gasoline engine is an engine that uses gasoline as fuel to convert internal energy into kinetic energy. Due to the small viscosity and fast evaporation of gasoline, gasoline can be injected into the cylinder with the gasoline injection system. After being compressed to a certain temperature and pressure, it can be ignited with a spark plug to expand the gas and do work. Gasoline engine is characterized by high speed, simple structure, light weight, low cost, stable operation and convenient use and maintenance. Gasoline engines are widely used in cars, especially small cars. It includes many gasoline engine accessories. The engine body is the assembly matrix of all parts of the engine. It includes cylinder head, cylinder block and lower crankcase (oil pan). The cylinder head and
