[0044] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0045] Reference Figure 1-2 The utility model provides a device suitable for automatic covering of a dump truck, which is used to realize the automatic covering process of the dump truck compartment.

When one of the sliding plates 2 is slid, The remaining sliding plates 2 can move simultaneously; two driving structures are provided, and the two driving structures are respectively installed on the two outer side walls of the carriage 1, and the driving mechanism is used to drive at least one sliding plate 2 to move along the length direction of the carriage 1, thereby driving several sliding plates 2 to slide simultaneously; several support frames 4 are provided, and the support frames 4 are in a "ㄇ"-shaped structure. The support frames 4 are arranged along the width direction of the carriage 1, and the two ends of the support frames 4 are respectively connected to the sliding plates 2 on the two outer side walls of the carriage 1; the canopy 5 is located above the carriage 1, and the canopy 5 is installed on the support frames 4.

[0046] When in use, a group of sliding plates 2 respectively arranged on the two outer side walls of the carriage 1 and close to the front end are fixed, and then one of the remaining sliding plates 2 is driven to slide by the driving structure. Due to the connection of the first connecting rod 3, the remaining sliding plates 2 will slide at the same time, and can respectively drive the support frame 4 to move toward the rear of the vehicle, and then drive the canopy 5 installed on the support frame 4 to unfold synchronously, further realizing the covering process of the carriage 1. During the use of the utility model, the support frame 4 is used to drive the canopy 5 to move, instead of the canopy 5 driving the support frame 4 to move, which reduces the force on the canopy 5 during the covering process of the carriage 1, and can realize the uniform dragging process of the canopy 5, thereby reducing the damage to the canopy 5 and increasing the service life of the canopy 5.

[0047] Preferably, the utility model further comprises a first baffle plate 6, a sliding rod 7 and a second connecting rod 8.

Preferably, the second baffle 10 is arranged opposite to and adjacent to the first baffle 6 near the front end of the vehicle. A threaded rod 11 is rotatably connected between the second baffle 10 and one of the first baffles 6, and one of the sliding plates 2 is threadedly connected to the threaded rod 11. By rotating the threaded rod 11, one of the sliding plates 2 can be driven to move along the sliding rod 7, and then the remaining sliding plates 2 can be driven to move along the sliding rod 7, so as to realize the process of covering and uncovering the carriage 1.

[0051] Reference Figure 3-4 The driving mechanism also includes a driving assembly, a threaded sleeve 12 and a clutch plate 14. The driving assembly is used to drive the threaded rod 11 to rotate; the threaded sleeve 12 is rotatably connected in one of the sliding plates 2, the threaded sleeve 12 is threadedly connected to the threaded rod 11, and the outer wall of the threaded sleeve 12 is provided with a plurality of clutch grooves 13 at intervals along its axial direction; the clutch plate 14 is slidably connected to the inside of the sliding plate 2 along the radial direction of the threaded sleeve 12, and the clutch plate 14 is detachably connected to the clutch groove 13.

[0054] When in use, when the second baffle 10 or one of the first baffles 6 near the front end of the vehicle abuts against the unlocking plate 19, it can drive the unlocking plate 19 to slide in the second through hole, and further drive the sliding protrusion 18 to slide in the V-shaped groove 20, which can overcome the elastic force of the elastic member 16 to move the clutch plate 14 away from the threaded sleeve 12 until the clutch plate 14 disengages from the clutch groove 13. At this time, the threaded rod 11 and the threaded sleeve 12 rotate synchronously, and the threaded sleeve 12 and the sliding plate 2 slide relative to each other, and the sliding plate 2 no longer undergoes relative displacement. On the contrary, when the sliding plate 2 moves, the second baffle 10 or the first baffle 6 is no longer in contact with the unlocking plate 19, and under the action of the elastic member 16, the sliding protrusion 18 slides in the V-shaped groove 20, and synchronously, the unlocking plate 19 slides in the second through hole until the sliding protrusion 18 slides to the corner of the V-shaped groove 20. At this time, the clutch plate 14 will be embedded in the threaded sleeve 12 again. At this time, the threaded sleeve 12 and the unlocking plate 19 are relatively stationary, and rotating the threaded rod 11 can drive the sliding plate 2 to slide along the sliding rod 7.
