The power mechanism, the driving mechanism, the traveling mechanism and the like of the present invention are not different from the mechanism of the wheeled vehicle in the prior art, and therefore, they are not described in detail herein. As can be seen from fig. 1, compared with the wheeled vehicle in the related art, the present invention is mainly characterized in that an excavation mechanism for realizing an excavation function is provided at the front right of the driver's seat. Specifically, the excavating mechanism is provided on the frame 7 via the swivel device 6, and mainly includes hydraulic actuators 9 and 10, an excavator arm 5, and the like, and is operated by a steering mechanism.

The specific structure of the working mechanism, i.e., the excavating mechanism, according to the present invention will be described with reference to fig. 2 and 3. Turning first to fig. 2, there is shown a digging mechanism disposed on a vehicle frame 7. The excavating mechanism includes a hydraulic actuator 9, a hydraulic line 11, and the like, and is rotatable relative to the frame by the turning device 6. The excavating mechanism is connected to the swivel arrangement 6 by means of a mounting base 15. The rotation device further comprises an elastic limiting device comprising an elastic limiting member 13 (which may be a compression spring, for example), a mounting portion 14 and a limiting portion 12. The elastic stopper 13 is provided on the mounting portion 14, and rotates together with the rotating device 6 and the excavating mechanism, and the stopper portion 12 is provided on the frame and fixed to the frame. When the rotating device 6 is operated to rotate, the elastic limiting device can prevent the excavating mechanism from rotating beyond the limit and generating rigid impact with the frame.

See also figure 3. As can be seen in fig. 3, the rotating means 6 comprise a gearwheel 61 and a pinion 62; wherein the pinion 62 is arranged on the frame and driven by a power mechanism to rotate; the large gear 61 is rotatably disposed, is constantly engaged with the small gear 62, and is rotated by the small gear 62, thereby rotating the excavating mechanism disposed on the large gear 61.

Referring to fig. 4, a detailed description will be given of a specific structure of a frame 7 of a utility vehicle according to a first embodiment of the present invention. The main structure of frame 7 includes two side members 72 and two cross members 73, and further includes an excavating mechanism mounting portion 71 provided at the front of the frame, and a frame reinforcement 74 provided at the middle-rear portion of the frame. The number and location of frame reinforcements 74 are calculated and configured according to the operating mechanism and the particular power requirements.

The first embodiment of the present invention has been described in detail above. In the actual manufacturing process, the frame 7 is mainly modified by adopting a ground disc of a small agricultural vehicle, and the frame with the reinforced structure is arranged, and the excavating mechanism and the corresponding operating mechanism are arranged on the frame, so that the miniaturization of the engineering machinery is realized. The vehicle in the first embodiment can be configured in a narrow road, and the excavation mechanism can be rotated in a wide range, thereby achieving flexible work.

According to the utility vehicle of the first embodiment, since the special frame is calculated and manufactured on the basis of the existing agricultural vehicle, and the corresponding excavating mechanism and the operating mechanism are added, the manufacturing cost is greatly reduced, and the utility vehicle is particularly suitable for occasions with narrow space and occasions with low power demand. Typical applications of the present invention include, but are not limited to: the method comprises the following steps of excavating and loading sand and soil of a river beach, loading and transporting a small number of forest trees, excavating tombs, excavating and transferring a small number of objects in daily life and the like. In the running process, the excavating mechanism is placed backwards and is arranged in the carriage, and the overall size of the vehicle is not increased; when the excavator reaches the working site, the excavator is turned to an appropriate position by rotating the rotation mechanism.

Other embodiments of the present invention are described below with reference to fig. 5-7.

Firstly, on the basis of the first embodiment, a support structure 16 is added, which is located between the front and rear wheels of the vehicle, preferably in the vicinity of the driver's seat. The support structure 16 is preferably a hydraulic support leg that is capable of extending in the vehicle width direction and that, after extending to a certain length, projects a foot downwardly to provide support for the vehicle frame. The embodiment of fig. 5 differs from the first embodiment in that the mounting position of the swivel device is not in front of the vehicle body frame but in the rear position on the right side of the driver. This arrangement reduces the disturbance to the driver's view and facilitates the arrangement of the steering mechanism.

Fig. 6 shows a third embodiment of the utility model discloses a utility model. The main improvement of the embodiment is that the running gear is a crawler running gear 1' rather than a wheel running gear. The crawler-type traveling mechanism is more suitable for roads with bad road conditions than the wheel-type traveling mechanism, particularly roads with non-paved road surfaces and the like, such as inter-mountain roads, muddy dirt roads and the like.

Fig. 7 shows a fourth embodiment of the utility model discloses a utility model. This embodiment differs from the previous embodiments in that it does not include a car and the range of rotation of the excavating mechanism is also small. The embodiment is particularly suitable for structural improvement of an agricultural tractor, and the excavating function can be realized by additionally arranging a corresponding hydraulic device and an excavating mechanism.

In addition, although not shown in the drawings, obviously, the working mechanism of the present invention may not be limited to the excavating mechanism, but may be a lifting mechanism, for example, a hydraulic lifting mechanism is provided to transport people to a higher position, so as to realize the installation and maintenance of the street lamp.

The detailed structure, manufacturing method, working process, etc. of the present invention have been described above, and possible modifications are introduced. Without departing from the spirit of the present invention, those skilled in the art can make improvements according to the technical solution of the present invention.
