Abstract

The utility model relates to a pavement grooving machine, which comprises a pedestal and a cutting saw blade, wherein a cutting saw blade hood is arranged above the cutting saw blade, a mudguard plate is arranged behind the cutting saw blade, the mudguard plate comprises an upper mudguard plate and a lower mudguard plate, the upper mudguard plate is fixed on the cutting saw blade hood, and the lower mudguard plate is fixed on the pedestal. When the cutting saw blade is contacted with a cut face, the bottom end of the upper mudguard plate is lower than the top end of the lower mudguard plate, and the pavement grooving machine can more effectively prevent splash objects brought by cutting and extend service life of mudguard plates.

Description

A kind of joint cutter

Technical field

The utility model relates to a kind of joint cutter, is specifically related to a kind of joint cutter that cuts various hard grounds.

Background technology

Joint cutter is a kind of visual plant that is used for road construction, extensively applies in the fluting, operation such as finishing cut-out etc. of concrete, flexible pavement.Along with the fast development of road traffic industry, the road joint cutter is widely used.

Existing joint cutter comprise the hinged underframe of pedestal between pedestal and trailing wheel, on the underframe by the cast-cutting saw slice of cutting spindle mounted, the cast-cutting saw slice guard shield that is fixed in underframe be installed on cast-cutting saw slice top, be arranged at the dashboard on the cast-cutting saw slice guard shield.Owing to only on the cast-cutting saw slice guard shield, be provided with a dashboard in the existing joint cutter, in order to guarantee that the splash that cuts each stage generation all can effectively be stopped, this dashboard need be made longlyer, and must adopt flexible material to make, like this, in the joint cutter course of work, dashboard Lower Half branch often bending and and ground friction, thereby cause dashboard to damage easily, application life is shorter, and because of this dashboard soft, so the plate washer edge can not effectively stop the splash that brings of cutting when deeply cutting.

The utility model content

The purpose of this utility model provides a kind of joint cutter with novel dashboard, can stop the splash that cutting brings under the operating mode of various road surfaces more effectively, and reduced the bending of dashboard and the friction on dashboard and ground, prolonged the application life of dashboard.

To achieve these goals, the technical solution adopted in the utility model is: a kind of joint cutter with novel dashboard, comprise pedestal and cast-cutting saw slice, above cast-cutting saw slice, be covered with the cast-cutting saw slice guard shield, rear at cast-cutting saw slice is provided with dashboard, described dashboard comprises dashboard and undershield, the described dashboard of going up is fixed on the cast-cutting saw slice guard shield, described undershield is fixed on the pedestal, when cast-cutting saw slice contact cut surface, the bottom of last dashboard is lower than the top of undershield.

The described dashboard of going up is when cast-cutting saw slice is done the deepest cutting, and its dashboard bottom is a little more than ground.

The described dashboard of going up is made by rigid material, and described undershield is made by flexible material.

Be installed with linking arm on the described pedestal, described undershield is fixedly connected on the pedestal by this linking arm.

In the utility model, because described undershield and last dashboard are used, can stop the splash that cutting brings under the operating mode of various road surfaces effectively, owing to keep off the fixed-site of mud mud plate down, design with last dashboard length, avoid too much friction in upper and lower dashboard and ground and the frequent damage that bends the dashboard that causes, prolonged the application life of dashboard.In addition, because last dashboard adopts rigid material to make,, can more effectively stop for deeply cutting a large amount of splashes that bring.

The specific embodiment

Joint cutter as shown in Figure 1, comprise the hinged underframe 2 of pedestal between pedestal 1 and trailing wheel, at the cast-cutting saw slice 3 by the cutting spindle mounted on the underframe 2, above cast-cutting saw slice 3, be covered with cast-cutting saw slice guard shield 4, rear at cast-cutting saw slice 3 is provided with dashboard, described dashboard comprises dashboard 5 and undershield 6, the described dashboard 5 of going up is fixed on the cast-cutting saw slice guard shield 4, described undershield 6 is fixed on the pedestal 1, when cast-cutting saw slice 3 contact cut surfaces, the bottom of last dashboard 5 is lower than the top of undershield 6.The bottom of last dashboard 5 is when cast-cutting saw slice is done the deepest cutting, and its dashboard bottom is a little more than ground.

Be installed with linking arm 7 on the pedestal 1, undershield 6 is connected with pedestal 1 by linking arm 7; Undershield 6 is close to linking arm 7, fixes by bolt 8 and nut 9; Linking arm 7 is fixedlyed connected with pedestal 1, for not influencing the support strength of pedestal 1, adopts welding fixing.

Last dashboard 5 is made by rigid material, and described undershield 6 is made by flexible material.

In the present embodiment, following fender 6 adopts two fixed points to fix with linking arm 7, can adopt plural fixed point to fix for strengthening fixed effect.

In the present embodiment; the fixed form of undershield and linking arm is a bolt; linking arm and described pedestal adopt the welding fixed form; in the specific implementation; the fixed form of undershield and linking arm can also be riveted and fixed; linking arm and pedestal also can adopt linking arm and the described pedestal snap fit with locking and fixing device; locking and fixing device can be the nut bolt locking device; suchlike variation all belongs to the replacement that is equal to of present embodiment relevant art feature, only has the technical scheme of similar variation must belong to protection domain of the present utility model.
