Problems solved by technology

The disadvantages of the above two utility model patents applied for earlier are that the structure is complex, which increases the energy consumption of the road sweeper, and fails to improve the cleaning quality by increasing the proportion of air flow that does useful work in the air intake.

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] A suction nozzle of a sweeping road sweeper, comprising a suction cylinder 4, a nozzle seat 2, a roller 5, a roller bracket 6, a rubber baffle 1, and a surrounding plate 7, etc., and the roller bracket 6 is installed on the nozzle seat 2 On the top, three or four rollers 5 are respectively installed on the roller bracket 6, and the left, rear and right panels 7 are connected to each other, and the upper end is installed under the suction nozzle seat 2, and the rubber baffle 1 is installed at the front entrance of the suction nozzle. The upper end of the rubber baffle 1 is installed under the suction nozzle seat 2, the lower ends of the rubber baffle 1 and the left, rear and right three-sided enclosures 7 are close to the ground, and the suction nozzle seat 2 covers the rubber baffle 1 and the connected left, rear, and right side...

Abstract

The invention discloses a sweep and suction nozzle of sweep road car. By using the suction nozzle of sweep road car the clearing quality is good when the road surface is cleared. The clearing rate is improved and the energy consumption can not be added. The using cost need not be added, which comprises suction cylinder 4, seat of suction nozzle 2, rolling wheel 5, rack for rolling wheel 6, rubber baffle 1 and wall board 7 so on. A silicon baffle 3 is set vertically to the seat of suction nozzle 2 in inner cavity of suction nozzle, at the back of rubber baffle 1 and at the front of the lower mouth of suction cylinder 4. Notches with 60mm or so upwards are set on the lower end of baffle in every 30mm. when the sweep road car of sweep and suction works, the lower end of rubber baffle 1 bends so that the section area of air input is decreased and the air speed is increased. After the air enters into the suction nozzle, it flows near the ground for a long distance to pass through the baffle 3, it turns a corner to enter into the suction cylinder 4. The air through the suction nozzle can take garbage with bigger weight, bigger cubage and more quantity into the suction cylinder 4. Finally, it is sent into dustbins.

Description

technical field [0001] The invention relates to a suction nozzle of a road sweeper, in particular to a suction nozzle of a sweeping type road sweeper. Background technique [0002] Road sweepers have been increasingly used in the cleaning and cleaning of urban roads, highways, squares, schools, factories, parks, and community roads. Because some roads often have some sand and gravel left by vehicles transporting building materials, and there are more sand and garbage on the outer ring roads of some cities, the sweeping suction road sweeper often does not sweep and suck clean when cleaning these roads. [0003] Some road sweeper manufacturers and research institutions at home and abroad generally adopt three improvement schemes to improve the quality of sweeping and suction road sweeper cleaning operations: 1. Increase the power of the fan, increase the air flow and increase the negative pressure; The air outlet is connected with 1-2 ventilation pipes connected to the lower ...
