[0036] In other embodiments, the second jet section 422 can also be a wedge-shaped channel with an airflow cross-sectional area gradually increasing along the airflow direction, and the minimum airflow cross-sectional area in the wedge-shaped channel is larger than the minimum airflow cross-sectional area of the first jet section 421 .
[0037] The cross section of the dust collection tank body 41 is circular, and the width of the notch 5 is much smaller than the diameter of the dust collection tank body 41 . That is, the dust collecting groove 41 belongs to a large-volume dust collecting chamber relative to the width of the groove.

The invention discloses a dust collector and a sweeping truck; the dust collector comprises a cylindrical shell body (3), of which both ends are provided with openings; a supporting shaft (1) located at inside of the shell body (3) and extended along the length direction of the shell body (3); several rotational flow blades (3) installed on the supporting shaft (1), wherein the rotational flow blades (3) are extended towards the inner wall side of the shell body (3) and have a setting gap with the inner wall of the shell body (1); the dust collector further comprises a dust collecting tank (4) arranged at the outside of the shell body (3) and interconnected with the shell body (3); the dust collecting tank (4) is extended along the length direction of the shell body (3). The dust collector solves the problems that the existing dust collector is poor in dust removal effect, large in occupied space and high in manufacturing cost, and is especially suitable for the sweeping truck.
Description
technical field [0001] The invention belongs to the field of road sweeper design, in particular to a dust removal device for a road sweeper. Background technique [0002] The dust removal device of the road sweeper is an important part that affects the performance of the whole vehicle of the road sweeper. Under the same working conditions, the quality of the dust removal device directly determines the cleaning rate, cleaning ability and dust removal effect of the whole vehicle of the road sweeper. Under the premise of ensuring the cleaning performance, the dust removal device with superior dust removal performance can greatly reduce the long-term wear of the dust particles on the fan and the damage to the dynamic balance of the fan rotor, greatly reduce the dust concentration in the air at the fan outlet, and prolong the use of the road sweeper life. Therefore, it is an inevitable way to implement the performance optimization design of the road sweeper starting from the dus...
