[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 5 The utility model provides a technical solution: a tipping machine hook structure and a tipping machine thereof, comprising a tipping machine 1, a casing 2 is respectively arranged on the left and right sides of the front end of the tipping machine 1, the inner cavities of the two casings 2 are respectively provided with a lifting assembly, the front ends of the two lifting assemblies respectively extend to the front ends of the two casings 2 and are respectively fixedly connected with a fixing box 3, the inner cavity of each fixing box 3 is provided with an adjusting assembly, and a reset plate 4 is arranged on the side where the two adjusting assemblies are close to each other. Through the setting of the lifting assembly, the fixing box 3 can drive the adjusting assembly and the reset plate 4 to slide up and down, so that the height of the reset plate 4 and the hook are at the same horizontal line, and through the setting of the adjusting assembly, the reset plate 4 can slide toward the middle of the front end of the tipping machine 1, thereby making the hook upright to a state vertical to the tipping machine 1, facilitating the connection of the hook, solving the problem that the tipping machine 1 in the prior art does not have a positive hook structure in actual use, resulting in the problem that the hook is tilted after unloading and needs to be manually reset before the hook can be hung.

[0024] In this embodiment, the lifting assembly includes a first motor 5, a screw rod 6, a slider 7, a slide 8, a moving rod 9 and a limit assembly. The first motor 5 is arranged at the top of the casing 2, and the output end of the first motor 5 extends to the inner cavity of the casing 2. One end of the screw rod 6 is rotatably connected to the bottom end of the inner cavity of the casing 2 through a bearing, and the other end of the screw rod 6 is fixedly connected to the output end of a motor. The slider 7 is screwed to the outer wall of the screw rod 6, and the slide 8 is opened at the front end of the casing 2. The moving rod 9 can be slidably embedded in the inner cavity of the slide 8. One end of the rod 9 is fixedly connected to the slider 7, and the other end of the moving rod 9 is fixedly connected to the fixed box 3. The limiting assembly is arranged on the rear side of the inner cavity of the casing 2 and is fixedly connected to the slider 7, so that the first motor 5 drives the screw rod 6 to rotate. Under the action of the rotational force of the thread on the outer wall of the screw rod 6, when the screw rod 6 rotates, the slider 7 can drive the fixed box 3, the rack 16 and the reset plate 4 to slide up and down through the moving rod 9 under the limiting action of the limiting groove 10 and the limiting block 11, so that the height of the reset plate 4 is at the same horizontal line as the hook.

[0025] In this embodiment, the limit assembly includes a limit groove 10 and a limit block 11. The limit groove 10 is opened on the rear side of the inner cavity of the casing 2. The limit block 11 can be slidably embedded in the inner cavity of the limit groove 10 and fixedly connected to the slider 7. Under the joint action of the limit groove 10 and the limit block 11, the slider 7 can be prevented from rotating with the screw rod 6 when the screw rod 6 rotates, thereby improving the stability of the lifting assembly when in use.

[0026] In this embodiment, the inner cavity of the limiting groove 10 is matched with the outer wall of the limiting block 11 and both are in a "T" shape, so that one end of the limiting block 11 can always remain embedded in the inner cavity of the limiting groove 10, thereby improving the stability of the limiting assembly during use.

[0027] In this embodiment, the adjustment component includes a second motor 12, a gear 13, a connecting component and a rack 16. The second motor 12 is arranged at the front end of the fixed box 3. The output end of the second motor 12 extends to the inner cavity of the fixed box 3 and is rotatably connected to the rear side of the inner cavity of the fixed box 3 through a bearing. The gear 13 is fixedly sleeved on the output end of the second motor 12. The connecting component is arranged at the bottom end of the inner cavity of the fixed box 3. The rack 16 is arranged at the top of the connecting component. The second motor 12 is started to drive the gear 13 to rotate. Since the gear 13 is meshed with the rack 16, when the gear 13 rotates, the rack 16 can be driven to reset along a straight line to the middle of the front end of the tipping machine 1 under the limiting action of the connecting block 15 and the connecting groove 14, so that the hook is straightened to a state perpendicular to the tipping machine 1, which facilitates the connection of the hook.

[0028] In this embodiment, the rack 16 is meshed with the gear 13 .

[0029] In this embodiment, the connection assembly includes a connection slot 14 and a connection block 15 .

[0030] In this embodiment, the connection groove 14 is provided at the bottom end of the inner cavity of the fixing box 3 .

[0031] In this embodiment, the connection block 15 is slidably embedded in the inner cavity of the connection groove 14 and fixedly connected to the bottom end of the rack 16 .

[0032] In this embodiment, the inner cavity of the connecting groove 14 is matched with the outer wall of the connecting block 15 and both are dovetail-shaped, so that one end of the connecting block 15 can always remain embedded in the inner cavity of the connecting groove 14, so that the rack 16 always remains in meshing with the gear 13.

[0033] The use method and advantages of the utility model: When in use, the working process is as follows:

[0034] Start the first motor 5, so that the first motor 5 drives the screw rod 6 to rotate. Under the action of the rotational force of the outer wall thread of the screw rod 6, when the screw rod 6 rotates, the slider 7 can drive the fixed box 3, the rack 16 and the reset plate 4 to slide up and down through the moving rod 9 under the limiting action of the limiting groove 10 and the limiting block 11, so that the height of the reset plate 4 is at the same horizontal line as the hook. Start the second motor 12, so that the second motor 12 drives the gear 13 to rotate. Since the gear 13 is meshed with the rack 16, when the gear 13 rotates, the rack 16 can be driven to reset along a straight line to the middle of the front end of the tipping machine 1 under the limiting action of the connecting block 15 and the connecting groove 14, so that the hook is straightened to a state perpendicular to the tipping machine 1, which is convenient for the connection of the hook and solves the problem that the tipping machine 1 in the prior art does not have a positive hook structure during actual use, resulting in the tilting of the hook after unloading and the need for manual reset before the hook can be hung.
