Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
The utility model provides a kind of dozer assembly, comprises dozer body, and described dozer assembly also comprises: at least one first dozer, and described the first dozer and described dozer body are slidably matched; Driving mechanism, drives and is connected with described the first dozer; Described driving mechanism drives described the first dozer to stretch out outside described dozer along described dozer body length direction, or is shunk back outward by described dozer.
The first dozer of the present utility model and dozer body are slidably matched, and this is external under the driving of driving mechanism, can to stretch out dozer, increase the soil shifting area of whole dozer.Can carry out smooth dozing on a large scale without transverse shifting excavator, alleviate driver's operation intensity, greatly increase operating efficiency.
Shown in Fig. 1, the dozer assembly that the utility model provides, comprises dozer body 4, also comprises the first dozer 1.The first dozer 1 is slidably matched with dozer body 4; Driving mechanism 3 drives and is connected with the first dozer 1; Driving mechanism 3 drives the first dozer 1 to stretch out outside dozer along described dozer body 4 length directions, or is shunk back outward by described dozer.Each the first dozer 1 is under the driving of driving mechanism 3, and the distance of stretching out outside dozer body 4 is about L.
Specifically, the first dozer 1 is installed on the described dozer body 4 soil-shifting faces for dozing.The effect of the first dozer is to expand dozing face, installs and increases the stability of installing for convenient, and the dozer body in the present embodiment is mounted on soil-shifting face.
The connecting portion that offers sliding-rail groove 5, the first dozers 4 on dozer body 4 is stretched to the rear of described dozer body 4 by soil-shifting face by sliding-rail groove 5, connecting portion and driving machine 3 structures are hinged by bearing pin 2.
Driving mechanism 3 is installed on described dozer body to deviate from the one side of described soil-shifting face.Driving mechanism is arranged on
Driving mechanism is oil cylinder.Oil cylinder can be connected with the working connection of excavator, rushes oil or draining by controller control oil cylinder, to reach the object of driving.By oil cylinder different rush oil mass, determine different driving length, make the first dozer stretch out the length of dozer body adjustable.
The first dozer 1 of the present utility model is two, is arranged on respectively the two ends of dozer body 4 along the length direction of dozer body 4, is symmetric design.In the time needing the soil shifting area of enlarging soil shifting shovel, control driving mechanism and drive two the first dozers to extend, because two the first dozers are symmetric designs, the stability under loading while having ensured dozing.In addition, two driving mechanisms are respectively corresponding the first dozer to be driven, and make two the first dozers independent movable; And drive the first dozer to move in drives structure, the first dozer can stop at an arbitrary position, so just can meet different dozing area needs in sliding-rail groove.
Shown in Fig. 2, two the first dozers 1 are wherein the state in reclaiming with respect to dozer body 4.Under the effect of drives structure 3, the first dozer 1 connecting by bearing pin 2 moves to the innermost end of dozer body 4 along sliding-rail groove 5, together with baffle plate 6 is posted by with dozer body 4.Like this, baffle plate 6 can stop impurity to enter in the gap between dozer body 4 and the first dozer 1.
Shown in Fig. 3, one of them first dozer 1 is the state in reclaiming with respect to dozer body 4, and another first dozer 1 is the state in stretching out with respect to dozer body 4.Because drives structure of the each freedom of each the first dozer is controlled, so two the first dozers can be realized different states.
The utility model also provides a kind of excavator, comprises dozer assembly as above.
It should be noted that, this excavator is the excavator that comprises above-mentioned dozer assembly, and the implementation of above-mentioned dozer assembly embodiment is equally applicable in the embodiment of this excavator, also can reach identical technique effect, does not repeat them here.
Above-described is preferred embodiment of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
