These are the main uses of mini excavators

[BONOVO]

With the development of The Times and the progress of science and technology, the proportion of machines replacing labor is getting larger and larger, and the use of small construction machinery is becoming more and more extensive. The birth of small excavator, instead of the original bulky large wheeled excavator, compared with large excavator, small excavator low fuel consumption, good quality, low failure rate, not limited by space, more functions, can be applied to the following aspects:

In simple terms, from basic field weeding and trenching to greenhouse land repair; From the fertilization and loosening of the orchard to the work of the paddy field, there are busy small excavator. With different accessories, small excavatorcan do different jobs, digging, crushing, drilling, moving and grabbing materials; This is the charm of small excavators.

1: Price advantage: Because large excavatorare expensive, small excavators have certain advantages in price, ranging from 30,000 to 200,000, and small excavators are not inferior to large excavators in terms of performance;
2: Volume advantage: When the large excavatoris too narrow and complex working environment, it can do nothing, while the small excavator is small in size, flexible in movement, can work in a small space, not affected by space limitations, and is very popular. In the rural environment, the advantages of small excavators can be described as incisive and widely used.

According to the different rotation angles of the turntable, it can be divided into half rotary rotary mechanism and full rotary rotary mechanism. Suspended hydraulic excavatorusually use a semi-rotary rotary mechanism, and the rotation Angle is generally equal to or less than 180°. According to the structure of hydraulic motor can be divided into cylinder and blade hydraulic two categories

These transmission methods are powered by the oil cylinder, through the chain sprocket or steel rope pulley, rack and pinion, lever system to drive the working device around the rotating shaft. The first two angles are large, the torque is stable, and the cylinder does not swing, so it is easy to arrange, but the structure is complex. Rack gear transmission mechanism has two series of single rack and full rack cylinder, the Angle is generally 90°, 120° and 180°, and individual can reach 270°. The lever transmission mode is simple in structure, but the Angle is small, the torque is changed during the rotation process, and the cylinder is in the swing state, so it is inconvenient to arrange.

One of the three main parameters of an excavator is the volume of material that the bucket can hold. A tilting machine can be equipped with buckets with different bucket sizes according to different material densities. Reasonable selection of bucket capacity is one of the important means to improve operation efficiency and reduce energy consumption.
