technical field

The utility model relates to the technical field of sweeper appliances, in particular to a garbage collection device for sweepers.

Background technique

In the era of rapid urban construction, all aspects of urban maintenance are developing towards mechanization, especially in road maintenance and cleaning. Therefore, garbage sweepers came into being in this environment. Garbage sweeper is one of the road maintenance machinery with relatively early development and more market utilization in my country.

The sweeper is an important working device for various types of garbage sweepers to clean and collect garbage during the cleaning operation. When the garbage sweeper is in the cleaning operation, the sweeper is in contact with the cleaning road to carry out the garbage cleaning and collection operation.

The State Intellectual Property Office of China has published a patent with an application number of 2017112396183, which includes a sweeping disc, an adjustment mechanism for adjusting the up and down movement of the sweeping disc, and a motor for controlling the rotation of the sweeping disc. The motor is a hydraulic motor, and the motor enters and exits the oil pipe.

The present invention adopts a method of stabilizing the oil pressure difference to adjust the height of the sweeping disc from the ground, which is more convenient than directly detecting the pressure of the sweeping disc to the ground. , the detection results are more accurate.

Among them, when the sweeper is working, it is cleaned and recycled by sweeping the disc, but the following situations often occur during the sweeping process:

First, during the cleaning process of the existing sweeper, due to the high-speed rotation of the sweeper, dust is easily generated, so the sweeper is equipped with a dust suppression mechanism to reduce the flying of dust, but most of the devices use water to spray it. , in which it is necessary to inject the water source into the internal water storage tank. When the used water is sucked into the collection box after dust reduction, it cannot be used continuously, which increases the waste of water source.

Second, when the dust enters the collection box through the air suction channel, since the dust diffuses in the collection box, the exhaust port of the collection box is easily blocked, which increases the labor intensity of cleaning, and is inconvenient for precipitation collection and export.
