[0003] The existing automatic loaders mainly include two categories: one is the truss type loaders, when loading, the truck is driven under the truss, and the loading is carried out by the loading robot with three axes moving with the help of the visual system. This loading method is complex, expensive, and inefficient; the other is the horizontal conveyor type loaders, in which the loading conveying mechanism is placed on the lifting platform, and when loading, the truck is parked next to the loader, and the loading conveying mechanism moves up and down with the lifting platform to adjust the height between the conveying mechanism and the bottom of the truck box. This loading method is more flexible, low in cost, and high in loading efficiency. However, the width of the carriages varies greatly, and the size of the cargo stacks is also different. The conveying mechanism in the prior art is not easy to adjust according to the width of the carriages and the cargo stacks.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0029] like Figure 1-6 As shown, the utility model provides a width-adjustable conveying and loading mechanism, comprising a bottom support plate 1, a plurality of drive units are arranged side by side along the width direction of the upper side of the bottom support plate 1, the drive units comprise a middle drive assembly and side drive assemblies distributed on both sides of the middle drive assembly, the middle drive assembly and the side drive assembly both comprise a plurality of chain conveying assemblies;

[0030] The chain conveyor assembly includes a roller 2 arranged at the front end and a sprocket 3 arranged at the rear end. A conveyor chain 4 is wound between the roller 2 and the sprocket 3. When loading and unloading goods, the pile of goods is placed on the conveyor chain 4, and the pile of goods is driven by the sprocket 3 to move.

[0031] The conveying mechanism also includes a driving shaft 5 arranged at the rear end, the sprockets 3 of the intermediate driving assembly are fixedly installed on the driving shaft 5 at equal intervals, and the sprockets 3 of the side driving assembly are slidably installed on the driving shaft 5. When the sprockets 3 slide on the driving shaft 5, the distance between the chain conveying assemblies of the side driving assembly can be changed, so that the side driving assembly can be extended and retracted in the width direction of the bottom support plate 1.

[0032] A plurality of sliding keys are axially arranged on both sides of the driving shaft 5 , and sliding grooves are correspondingly arranged on the mounting hole of the sprocket wheel 3 .

[0033] Each chain conveying assembly of the side drive assembly includes two parallel square tubes 6 and two sprockets 3. The two square tubes 6 are fixedly connected. A sprocket 3 is correspondingly provided at the rear end of each square tube 6. The sprocket 3 is rotatably mounted on a bracket 7. The bracket 7 is fixedly connected to the two square tubes 6. A roller 2 is rotatably mounted at the front end of each square tube 6. A conveying chain 4 is wound between the roller 2 and the sprocket 3 of each square tube 6.

[0034] A plurality of spacing adjustment devices are provided on the side of the side drive assembly away from the middle drive assembly, and the spacing adjustment devices include a screw rod 13, and the screw rod 13 transversely penetrates the square tube 6 of the chain conveying assembly; a nut 14 is fixedly installed between the two square tubes of the innermost chain conveying assembly of the side drive assembly, and a bearing 15 is installed between the two square tubes 6 of the outermost chain conveying assembly, the screw rod 13 is rotatably matched with the bearing 15 between the two outermost square tubes 6, and the screw rod 13 is axially fixedly connected to the two outermost square tubes 6, the screw rod 13 can only rotate relative to the square tube 6, but cannot slide axially relative to the square tube 6; the front end of the screw rod 13 is rotatably matched with the nut 14.

[0035] The spacing adjustment device also includes a drive motor 11, which is slidably mounted on the fixed frame 9 through a slide rail 10. The drive motor 11 is connected to the telescopic rod of the cylinder 8. The cylinder 8 telescopes and drives the drive motor 11 to slide on the fixed frame 9. A sleeve 12 is fixedly mounted on the drive shaft of the drive motor 11. The end of the screw rod 13 is a hexagonal head, and the sleeve 12 cooperates with the hexagonal head at the end of the screw rod 13.

[0036] When the width of the side drive assembly needs to be narrowed, the telescopic rod of the cylinder 8 contracts and pulls the drive motor 11 to move inward, so that the sleeve 12 matches the end of the screw rod 13, and the drive motor 11 is started to drive the screw rod 13 to rotate. The screw rod 13 and the nut 14 rotate and match to move the screw rod 14 inward. Since the screw rod 13 is axially fixed to the two outermost square tubes 6, the screw rod 13 drives the chain conveying assembly other than the innermost chain conveying assembly to move inward, and finally achieves contraction; when the width of the side drive assembly needs to be narrowed, the drive motor 11 is reversed, so that the screw rod 13 pulls the chain conveying assembly other than the innermost chain conveying assembly outward to achieve widening. In this way, the width of the conveying mechanism can be adjusted according to the width of the cargo stack and the carriage, making loading more convenient.

[0037] A limit link 16 is provided between the square tubes of different chain conveyor assemblies. The limit link 16 slides through the square tubes 6 of different chain conveyor assemblies. Limit caps 17 are provided at both ends of the limit link 16. The limit caps 17 block the outer side of the square tube 6. The limit link 16 is used to limit the maximum distance between two adjacent chain conveyor assemblies. When the conveying mechanism is widened, the distance between the chain conveyor assemblies will not be too large.

[0038] A conveying motor 18 is also provided at the rear end of the bottom support plate 1 , and the conveying motor 18 drives the driving shaft 5 to rotate, thereby providing power for the transmission of the conveying chain 4 .

[0039] The specific working principle of the utility model:

[0040] A plurality of drive units are arranged side by side along the width direction of the upper side of the bottom support plate 1, and the drive units include a middle drive assembly and side drive assemblies distributed on both sides of the middle drive assembly, and the middle drive assembly and the side drive assembly each include a plurality of chain conveying assemblies; the distance between the plurality of chain conveying assemblies of the side drive assembly is adjustable.

[0041] When it is necessary to narrow the width of the side drive assembly, the telescopic rod of the cylinder 8 contracts to pull the drive motor 11 inward, so that the sleeve 12 cooperates with the end of the screw rod 13, and the drive motor 11 is started to drive the screw rod 13 to rotate. The screw rod 13 and the nut 14 rotate and cooperate to move the screw rod 14 inward. Since the screw rod 13 is axially fixed to the two outermost square tubes 6, the screw rod 13 drives the chain conveying assemblies other than the innermost chain conveying assembly to move inward, and finally achieves contraction; when it is necessary to narrow the width of the side drive assembly, the drive motor 11 is reversed, so that the screw rod 13 pulls the chain conveying assemblies other than the innermost chain conveying assembly outward to achieve widening.

[0042] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
