[0002] Cargo loader is one of many logistics and transportation equipment. It is mainly suitable for the transmission, loading and unloading of goods. It can greatly shorten the distance of manual round-trip material transportation. The loader can be freely extended and retracted in the length direction and the length of the conveyor can be controlled at any time. The chain conveyor efficiently transports materials for loading and unloading. Therefore, cargo loader is widely used in logistics centers, corporate warehousing, post offices, express delivery, airports, fertilizers, flour, food, beverages, tires and other companies for loading or unloading of goods.

[0003] For example, a loading device in a Chinese patent (CN207451123U) includes a vehicle body, a robot and a receiving device, wherein the robot and the receiving device are both installed on the vehicle body, the receiving device is used to receive objects, the robot is used to lift the objects from the receiving device and place the objects at a preset position, and the receiving surface of the receiving device is height-adjustable so that the receiving device can be connected to object conveying devices with different conveying heights. By arranging a robot, the utility model can effectively reduce manual labor, shorten loading time, and improve loading efficiency; by arranging a receiving device and adjusting the receiving surface height of the receiving device, the receiving device can still be smoothly connected to the object conveying device when the conveyed height of the object changes, thereby improving the adaptability of the loading equipment.

[0004] The above scheme also has the following technical deficiencies. The height adjustment of the bearing surface of the receiving device in the above scheme is limited by the height of the vehicle body itself, and the bearing surface cannot be adjusted to a height below the contact surface between the receiving device and the vehicle body. Therefore, it is difficult to load goods whose height is lower than the contact surface between the receiving device and the vehicle body. Based on this, a step-by-step unmanned loading equipment is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a step-by-step unmanned loading equipment, which has the advantages of adjusting the conveyor platform body to a height close to the ground to load goods, thereby solving the problem that the prior art cannot load goods close to the ground.

The linear module is located between the front and rear pairs of vertical rods. On the linear module, a hydraulic cylinder is fixed. On the telescopic end of the hydraulic cylinder, a clamping mechanism is provided;

[0007] The goods receiving mechanism includes a rotating rod rotatably connected to the left side inside the two bottom plates. On the front and rear ends of the rotating rod, stoppers are fixed. On the outer surface of the rotating rod, a connecting plate is fixed. On the top side of the connecting plate, a conveyor table body is fixed. On the bottom side of the conveyor table body, two hinge seats are fixed. On the hinge seats, support plates are hinged. On the bottom sides of the two support plates, a mounting plate is fixed. Inside the mounting plate, four bolt holes are opened.

[0008] Furthermore, the clamping mechanism includes a moving plate fixed on the telescopic end of the hydraulic cylinder. On the front side of the moving plate, a motor is fixed. On the output shaft of the motor, a bidirectional lead screw is fixed. On the outer surface of the bidirectional lead screw, two sliders are threadedly connected. On the top sides of the sliders, two limit blocks are fixed. On the bottom sides of the sliders, clamping plates are fixed.

[0009] Furthermore, through holes are opened on the right sides inside the two bottom plates. The rotating rod rotates in the through holes. The opposite sides of the two stoppers are respectively in contact with the opposite sides of the two bottom plates.

[0010] Furthermore, a bearing seat is fixed on the rear side inside the moving plate. The bidirectional lead screw rotates in the bearing seat.

[0011] Furthermore, a chute is opened on the top side of the inner wall of the moving plate. The two limit blocks slide in the chute.

[0012] Furthermore, the cross section of the moving plate is U-shaped. Rubber pads are fixed on the opposite sides of the two clamping plates.

[0013] Compared with the prior art, the technical solution of the present application has the following beneficial effects:
