The utility model provides a technical scheme: a grain loading and unloading machine is structurally shown in figures 1-3 and comprises a rotator and an ejector, wherein the ejector comprises an ejector body 1, a scissor type telescopic structure is arranged in the ejector body 1 and comprises a first driving arm 11 and a first driven arm 12, the first driving arm 11 is connected with a second driving arm 13, the first driven arm 12 is connected with a second driven arm 14, the first driving arm 11 is hinged with the first driven arm 12, the second driving arm 13 is hinged with the second driven arm 14, and an ejection oil cylinder 15 is arranged in the opening of the first driving arm 11 and the second driving arm 13. The pallet fork 2 is arranged below the ejector machine body 1 at intervals and used for removing the frictional resistance between the ejector machine body 1 and the pallet fork 2. The rotator structure is as shown in fig. 4 and 5, and comprises a first box 3, the first box 3 and a second box 4 are fixed by a first bolt 19 to form a hollow structure, a first gear 5 is arranged on the upper side of the hollow accommodating structure, a first shaft 6 is arranged in the center of the first gear 5 in a penetrating way, a first gear key 23 is arranged on the first shaft 6, a first bearing cover 16 is arranged at the front end of the first shaft 6, the second bearing cover 17 and the second box 4 are fixed by a second bolt 20, a third bearing cover 18 is arranged at the rear end of the first shaft 6, and the third bearing cover 18 and the first box 3 are fixed by a fourth bolt 22. First bearings 7 are arranged on two sides of the first shaft 6, second bearing covers 17 are arranged outside the first bearings 7, the second bearing covers 17 and the second box body 4 are fixed through third bolts 21, the lower side of the first gear 5 is meshed with the second gear 8, and second gear keys 24 are arranged at the lower ends of the second gear 8. The front end of the rotator is provided with a flange 9, the rear end of the flange 9 is provided with two second bearings 10, and the flange 9 is connected with the rotator.

The working principle of the ejector is as follows: at the minimum position of the scissor type telescopic structure, after the ejector forklift reaches a goods stacking designated position, the multi-way valve is operated to convey system pressure oil to the rear cavity of the ejection oil cylinder 15, the ejection oil cylinder 15 extends to drive the first driving arm 11 and the second driving arm 13 to rotate relatively and move forwards, so that the first driven arm 12 and the second driven arm 14 are driven to move synchronously with the first driving arm 11 and the second driving arm 13, the ejection frame is always vertical to the ground and continuously moves forwards until the ejection frame reaches the maximum position, and grains are ejected. And then, the multi-way valve is operated reversely to convey system pressure oil to a front cavity of the push-out oil cylinder 15, the push-out oil cylinder is shortened, the first driven arm 12, the second driven arm 14, the first driving arm 11 and the second driving arm 13 move reversely during pushing, and the push-out frame continuously moves backwards until the push-out frame retracts to the minimum position, so that a working cycle is completed. The pusher replaces the carriage, the goods blocking rack and the fork part of the common forklift, and is directly installed and connected on the rotator of the hoisting system, thereby being beneficial to reducing the structural size and the dead weight of the pusher and improving the effective bearing capacity.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
