[0023] like Figures 1-5 As shown, the self-dumping garbage truck with grab bucket provided in this embodiment of the invention includes a chassis 10, a self-dumping bucket 20 disposed on the chassis 10, and a steering crane 30 disposed on the chassis. The grab bucket body 40 is located at the end of the steering crane 30. The grab bucket body 40 includes two grab petals 41 that perform grabbing and releasing actions. Each grab petal 41 is provided with at least one rotation adjustment mechanism 42 and a plate 43 connected to the rotation adjustment mechanism 42. The rotation adjustment mechanism 42 includes a swing arm 421, which is hinged to the plate 43 and drives the plate 43 to fill the end area of ​​the grab petal 41.

[0024] Compared with the prior art, the self-dumping garbage truck with a grab bucket provided in this embodiment, when the rotation adjustment mechanism 42 operates to drive the swing arm 421 to rotate, rotates the plate 43 to the grab tooth end of the corresponding grab petal 41, forming two continuous grabbing components, which can grab relatively broken garbage. This is the first working mode of the self-dumping garbage truck, such as... Figure 1 As shown; when the rotation adjustment mechanism 42 operates, it drives the swing arm 421 to rotate in the opposite direction, rotating the plate 43 to the connecting end of the corresponding grabbing petal 41, forming a discrete structure at the grabbing tooth end of the grabbing petal 41, which facilitates the grabbing of large waste items. This is the second working mode of the self-dumping garbage truck, as shown. Figure 2 As shown, for items such as old sofas, tables, chairs, mattresses, and cabinets, when transferring garbage from the garbage truck to a designated location, the dump truck can first be switched to working mode two to transfer large items. After the large items are processed, switching the dump truck to working mode one allows it to grab the more fragmented garbage remaining at the bottom of the dump truck bed 20, avoiding the difficulty of transferring the garbage to the designated location by simply dumping the garbage from the dump truck bed 20. This also allows for a faster switch between working modes, improving the efficiency of garbage transfer.

[0025] In the embodiment, the rotating adjusting mechanism 42 further comprises a driving rotating mechanism, an execution end of the driving rotating mechanism is provided with a driving wheel 422 and a rotating shaft 423 coaxially connected with the driving wheel 422, the rotating shaft 423 is fixedly connected with the grabber 41, and the driving wheel 422 is rigidly connected with the swing arm 421. The driving rotating mechanism is fixed on the grabber 41, and after being started, the driving wheel 422 can be driven to rotate, the swing arm 421 rigidly connected with the driving wheel 422 is driven to swing, and the plate 43 moves along an arc track to approach or move away from the grab tooth end of the grabber 41.

[0026] In one embodiment, the driving rotating mechanism comprises a linear driver 424 and a rack 425 rigidly connected to an end of the linear driver 424, the rack 425 is engaged with the driving wheel 422, and the driving wheel 422 is a gear.

[0027] Specifically, the linear driver 424 is an electric cylinder, an oil cylinder or a gas cylinder, the linear driver 424 is fixedly installed on the inner side of the grabber 41, linear reciprocating movement of the linear driver 424 can drive the rack 425 to move linearly, thereby driving the driving wheel 422 engaged with the rack 425 to rotate, and the swing arm 421 is driven to swing. From the side of the grabber 41, the driving rotating mechanism is completely shielded by the grabber 41, and is not easy to be collided in use, thereby reducing the probability of damage. A protective cover (not shown in the figure) can also be installed on the grabber 41 to shield the side of the rotating adjusting mechanism 42 close to the garbage grabbing side, so as to avoid being collided by the garbage.

[0028] Further, the driving rotating mechanism further comprises a guide rail 426, the guide rail 426 is embeddedly and slidably connected with the rack 425. Specifically, the guide rail 426 is fixed on the inner side of the grabber 41 by welding or screws, recesses are formed on the guide rail 426, and protrusions are arranged on the rack 425. Through cooperation of the recesses and the protrusions, the rack 425 can maintain sufficient straightness when moving, the stability of the plate 43 in the two working modes is increased, and the rack 425 is not easy to be extruded out of the grabber 41.

[0029] Further, in order to improve the convenience of connection and disconnection of the linear driver 424 and the rack 425, the driving rotating mechanism further comprises a connecting block 427, two ends of the connecting block 427 are connected with the linear driver 424 and the rack 425 respectively.

[0030] In one embodiment, the connecting block 427 is L-shaped, so that the connecting block 427 can be fixedly connected with the rack 425 through the two vertical surfaces, the connection strength is improved, and interference between the output shaft of the linear driver and the grabber 41 is avoided.

[0031] In one embodiment, the plate member 43 is an arc-shaped plate, the plate member 43 is hinged with the rotation adjusting mechanism 42, and a plurality of limiting strips 44 are arranged on the inner side of the grab bucket 41. When the plate member 43 is moved to the limit position at both ends by the rotation adjusting mechanism 42, the inner side of the plate member 43 abuts against the limiting strips 44. In this way, the position of the plate member 43 in the working mode one and the working mode two can be accurately and stably fixed, and the rotation adjusting mechanism 42 is simplified.

[0032] In the embodiment, please refer to Figure 4 The grab bucket 41 is composed of two rigid plates 411 arranged in parallel, and one rotation adjusting mechanism 42 is arranged on each rigid plate 411. That is, a total of four rotation adjusting mechanisms 42 are arranged on the two grab buckets 41. The distance between the rigid plates 411 of the two grab buckets 41 is different, so the width of the two plate members 43 is different. Two rotation adjusting mechanisms 42 jointly drive one plate member 43. In this way, the rigid plates 411 are made of steel plates and have a dogtooth shape when viewed from the side, which facilitates grabbing garbage. The two rotation adjusting mechanisms 42 jointly driving one plate member 43 can improve the stability of the plate member 43.

[0033] In the embodiment, the grab bucket body 40 further comprises a hydraulic cylinder 45, a crank 46 and a mounting member 47. One end of the hydraulic cylinder 45 is rotationally connected with the connecting shaft of the crank 46, and the other end is hinged with one grab bucket 41. The two ends of the crank 46 are respectively hinged with the two grab buckets 41, and the mounting member 47 is hinged with the two grab buckets 41. In this way, the two ends of the crank 46 are swung by the extension and retraction of the hydraulic cylinder 45 to make the two grab buckets 41 perform a grabbing and releasing action. The mounting member 47 is detachably connected to the end of the turning and hoisting machine 30, and the spatial position can be adjusted by the turning and hoisting machine 30. The specific structure and working principle of the turning and hoisting machine 30 are not described in detail, which can be referred to the prior art.

[0034] In the embodiment, at least four hydraulic support columns 101 are arranged on the vehicle chassis 10, which can be supported on the bottom surface to maintain the stability of the vehicle chassis 10.
