Abstract

The utility model relates to an improved sweeping head of a road sweeper, which comprises a driving shaft bar and a brush head, wherein an automatic regulating apparatus for the brush head height is arranged between the driving shaft bar and the brush head and comprises a compression spring, a sleeve barrel and a telescopic barrel which are movably sheathed and connected mutually, wherein a strip-shaped spacing hole is arranged on the side wall of the sleeve barrel. A spacing stick matched with the strip-shaped spacing hole is arranged on the side wall of the rear part of the telescopic barrel, and the compression spring is positioned between the sleeve barrel and the telescopic barrel. The top end of the sleeve barrel is fixedly jointed with the lower end of the driving shaft bar, and the brush head is fixed to the lower end of the telescopic barrel by a connecting bolt. In the utility model, because the brush head which is directly contacted with a road surface is connected with a driving shaft bar fixed to high and low positions by the automatic regulating apparatus for the brush head height, which is composed of the compression spring, the telescopic barrel and the sleeve barrel, the brush head in the utility model can automatically regulate the height of the brush head according to the concave and convex condition of the road surface in use.

Description

Improved pavement sweeping machine cleaning head

Technical field

The utility model relates to the parts of using on a kind of improved road cleaning machinery equipment, particularly relates to a kind of improved pavement sweeping machine cleaning head.

Background technology

At present; existing be used to clean brush head on the cleaning head of using on the road cleaning machinery equipment on road surface when work and the distance between the vehicle frame fix; this makes existing cleaning head brush head on it in cleaning process to carry out in real time height according to the rough concrete condition in road surface and regulates; so scratched through regular meeting when the brush head on the existing cleaning head runs into ridge on the road surface in the process of using, and when running into the road surface recess, can't be cleaned.

Summary of the invention

The purpose of this utility model provides the improved pavement sweeping machine cleaning head that a kind of brush head on it can be regulated its high and low position automatically in real time according to the concavo-convex situation on road surface.

The purpose of this utility model is achieved in that a kind of improved pavement sweeping machine cleaning head, comprises drive shaft rod and brush head, also is provided with brush head height self-checking device between drive shaft rod and brush head;

Brush head height self-checking device comprises compression spring and mutual pivot bush unit sleeve and retracting cylinder together; Wherein have the bar shaped spacing hole on the sidewall of sleeve, be provided with the limit stick that matches with the bar shaped spacing hole on the sidewall at retracting cylinder rear portion, the compression spring is arranged between sleeve and the retracting cylinder; Fixedly connected with the lower end of drive shaft rod in the top of sleeve, brush head is fixedly installed on the lower end of retracting cylinder by connecting bolt.

Owing to be to link together among the utility model, so the brush head in the utility model can be regulated its high and low position automatically according to the concavo-convex situation on road surface when working by the drive shaft rod that the brush head height self-checking device that is made of compression spring, retracting cylinder and sleeve and high and low position are fixed with brush head that the road surface directly contact.

The specific embodiment

The utility model will be further described below in conjunction with drawings and Examples, and a kind of improved pavement sweeping machine cleaning head comprises drive shaft rod 1 and brush head 8, wherein also is provided with brush head height self-checking device between drive shaft rod 1 and brush head 8;

Brush head height self-checking device comprises compression spring 4 and mutual pivot bush unit sleeve 2 and retracting cylinder 6 together; Wherein on the sidewall of sleeve 2, have bar shaped spacing hole 3, on the sidewall at retracting cylinder 6 rear portions, be provided with the limit stick 5 that matches with bar shaped spacing hole 3, compression spring 4 is arranged between sleeve 2 and the retracting cylinder 6, under the effect of limit stick 5 and bar shaped spacing hole 3, the distance of bar shaped spacing hole 3 length can upwards be withdrawn or stretch out to the brush head 8 of retracting cylinder 6 and its lower end downwards; Fixedly connected with the lower end of drive shaft rod 1 in the top of sleeve 2, brush head 8 is fixedly installed on the lower end of retracting cylinder 6 by connecting bolt 7.

As shown in Figure 4, when the utility model uses, at first adjust the terrain clearance that frame 10 of the present utility model is installed, when 9 levels of road surface, limit stick 5 just in time is positioned near the middle part of bar shaped spacing hole 3; When brush head 8 ran into protrusion on the road surface 9, brush head 8 can be by upwards lifting behind the retracting cylinder 6 compression compression springs 4 like this; And when brush head 8 ran into pit on the road surface 9, under the compression elasticity effect of compression spring 4, retracting cylinder 6 can promote brush head 8 downwards, thereby brush head 8 can be cleaned the road surface 9 of caving in the pit.
