Background technique
Dozer is the usual means of the engineering machinery push cubic metre of earth and stone, and mini-excavator is frequently as a kind of standard configuration.It pushes away
Mamoty maximum width is generally with the chassis of complete machine the same as wide.Excavator dozer blade can play exclusion preceding object under certain operating condition
The effect of object, cleaning road surface or fixed main body, control stick are arranged in excavator driving room, and driver is controlled by control stick
The lifting of dozer, with the operation of assisted mining machine equipment.
With the continuous transformation replacement of urbanization and popularizing for mechanization of agriculture, the condition range of mini-excavator is increasingly
More, requirement is continuously improved, such as external certain areas, it is desirable that digging machine must not destroy ground when public way is implemented.And it is normal
Dozer is advised, when supporting ground, seamed edge certainly will occur relative motion and interaction, lead to knife plate with knife plate edge contacts
Cutting edge damages ground.
Utility model content
The technical problems to be solved in the utility model be excavator dozer blade as excavator front end support device when can damage
The problem of bad ground, and a kind of excavator dozer blade knife plate cutting edge protective device is provided, reduce excavator using dozer into
To the damage on ground when row front support.
The utility model is to realize that the technical solution of its purpose is such that construct a kind of excavator dozer blade knife plate cutting edge
Protective device, including dozer have knife plate in the lower part of dozer, it is characterised in that further include multiple being made of abrasive rubber
Cutting edge protective jacket, each cutting edge protective jacket pacified along the dozer knife plate length direction interval by removably
On the knife plate of the dozer, knife plate cutting edge holding tank, the knife of the dozer are provided on the cutting edge protective jacket
Plate cutting edge is located in the knife plate cutting edge holding tank.In the present invention, dozer knife plate sword is coated using cutting edge protective jacket
Mouthful, avoid dozer when as supporting role dozer knife plate cutting edge directly with ground face contact and destroy ground.
In above-mentioned excavator dozer blade knife plate cutting edge protective device, the bottom surface of the cutting edge protective jacket is plane or circular arc
Face.
In above-mentioned excavator dozer blade knife plate cutting edge protective device, the cross section of the cutting edge protective jacket is described in hook-shaped
The height for being located at the front side portion on front side of knife plate cutting edge holding tank on cutting edge protective jacket, which is greater than, to be located on rear side of knife plate cutting edge holding tank
The height of rear lateral portion, front side portion are fixedly connected on the leading flank of dozer knife plate.
In above-mentioned excavator dozer blade knife plate cutting edge protective device, the front side portion of the cutting edge protective jacket passes through bolt and institute
Knife plate is stated to be fixedly connected.Or cutting edge protective jacket mounting hole is provided on the knife plate, on the front side portion of the cutting edge protective jacket
It is provided with and front side portion one and the rubber pin that is inlaid in the cutting edge protective jacket mounting hole.
The utility model compared with prior art, in the present invention, coats dozer knife plate using cutting edge protective jacket
Cutting edge avoids dozer dozer knife plate cutting edge when as supporting role from directly destroying ground with ground face contact.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model excavator dozer blade knife plate cutting edge protective device.
Fig. 2 is the structural schematic diagram of cutting edge protective jacket in the utility model excavator dozer blade knife plate cutting edge protective device.
Parts title and serial number in figure:
Dozer 1, knife plate 11, bolt 2, gasket 3, cutting edge protective jacket 4, knife plate cutting edge holding tank 41, front side portion 42, rear side
Portion 43, through-hole 44.
Specific embodiment
Illustrate specific embodiment with reference to the accompanying drawing.
As shown in Figure 1, excavator dozer blade knife plate cutting edge protective device includes dozer 1, have in the lower part of dozer 1
Knife plate 11 is equipped with cutting edge protective jacket 4 along interval on dozer knife plate length direction.Cutting edge protective jacket 4 is by abrasive rubber system
At.
As shown in Fig. 2, the cross section of cutting edge protective jacket 4 in hook-shaped, is located at knife plate cutting edge holding tank 41 on cutting edge protective jacket 4
The height of the front side portion 42 of front side is greater than the height for being located at the rear lateral portion 43 of 41 rear side of knife plate cutting edge holding tank, and front side portion 42 is fixed
It is connected to the leading flank of dozer knife plate 11.The front side portion 42 of cutting edge protective jacket 4 is provided with through-hole 44, passes through bolt 2, gasket 3
And nut is fixedly connected with knife plate 11.After cutting edge protective jacket 4 is fixedly mounted, the cutting edge of the knife plate 11 of dozer 1 is located at cutting edge
In the knife plate cutting edge holding tank 41 of protective jacket 4.The bottom surface of cutting edge protective jacket 4 is plane, to be used as the support used time in dozer
To increase the contact area of cutting edge protective jacket and ground.In the specific implementation, bottom surface may be set to be cambered surface.
In the present embodiment, being fixedly connected by the realization of bolt 2 and knife plate 11 and removably of cutting edge protective jacket 4,
In dozer 1 as soil-shifting in use, being removed cutting edge protective jacket 4 by removing bolt 2.In digging operation and need to bulldoze
When shovel 1 destroys ground using and in order to avoid dozer as support, then cutting edge protective jacket 4 is mounted by means of bolts on
On knife plate.
In this excavator dozer blade knife plate cutting edge protective device, also it can be set on the front side portion of cutting edge protective jacket and sword
The rubber pin of mouth protective jacket one, setting accommodates the installation through-hole of rubber pin on knife plate, when installing cutting edge protective jacket,
Cutting edge protective jacket is first entangled to the cutting edge of dozer knife plate, then rubber pin is pressed into setting on knife plate and accommodates rubber pin
In installation through-hole, cutting edge protective jacket is fixed on knife plate by the friction between rubber pin and installation through-hole.
