DETAILED DESCRIPTION

[0018] The following is a further description of an orchard fruit box loading and unloading transport vehicle of the present invention in conjunction with the accompanying drawings and specific embodiments:

[0019] Figure 1 This is a structural schematic diagram of an orchard fruit box loading and unloading transport vehicle of the present invention. Figure 2 yes Figure 1In the figure, the orchard fruit box loading and unloading transport vehicle includes a frame body 4, which is two long beams parallel to each other. Wheels 8 are arranged on the two outer sides of the middle part of the frame body 4. A lifting shaft 20 is arranged between the two wheels 8. The two ends of the lifting shaft 20 are connected to the wheels 8 through crank arms 21. The crank arms 21 are connected to the wheel shafts 22 and the lifting shaft 20 through bearings. The lifting shaft 20 is fixed to the lower end surface of the frame body 4. Two connecting rods 19 are arranged on the lifting shaft 4. The ends of the connecting rods 19 are hinged to the hydraulic cylinder 15 through the pins 18. The other end of the hydraulic cylinder 15 is hinged to the welding On the oil cylinder support beam 14 on the lower end surface of the frame body, chains 6 are arranged on the two long beams of the frame body 4, the upper edge of the chain 6 is higher than the upper end surface of the frame body 4, the front and rear ends of the chain 6 are respectively provided with a driven sprocket 3 and a driving sprocket 10, the two driving sprockets 10 share the same main shaft 25, the driving sprocket 10 is directly driven by a hydraulic motor 12, an adjustment mechanism 13 for adjusting the tightness of the chain is arranged on the inner side of the frame body 4, a traction rod 11 connected to the power is arranged at the rear end of the frame body, and a vertically erected limit frame 9 is arranged on the upper end surface of the rear end of the frame body. In order to facilitate the front end of the frame body to extend into the bottom gap of the fruit box, a shovel head 1 in the shape of an inclined wedge is arranged at the front end of the frame body 4, and a bottom plate 24 wider than the long beam of the frame body is arranged on the lower end surface of the shovel head 1. A plurality of support wheels 5 for supporting the chain are arranged between the driven sprocket 3 and the driving sprocket 10 on the frame body. A block 2 is provided on the side of the driven sprocket 3 at the front end of the frame body to prevent the fruit box from sliding down. A linkage plate 17 is provided next to the connecting rod 19. The linkage plate 17 is provided with a driving long slot hole 26 and a joystick long slot hole 27. The block 2 is connected to the joystick long slot hole 27 through the block joystick 23. The pin 18 connecting the connecting rod and the oil cylinder is inserted into the driving long slot hole 26. The block 2 rotates around the driven sprocket shaft. The block joystick 23 is in a "U" shape. The two ends of the block joystick 23 are hinged to the two block 2, and the rear end of the block joystick 23 is simultaneously connected to the joystick long slot holes 27 of the two linkage plates. A return spring 16 is provided between the rear end of the linkage plate 17 and the side wall of the hydraulic cylinder 15.

[0020] When the hydraulic cylinder 15 is retracted, since the connecting rod 19 is welded to the lifting shaft 20, and the lifting shaft 20 is fixed to the lower end surface of the frame body 4, the lifting shaft 20 rotates downward around the wheel shaft 22, and the lifting shaft 20 will lower the frame body 4, and the front end of the frame body will touch the bottom surface. At the same time, under the action of the return spring 16, the linkage plate 17 moves backward, the block lever 23 is pulled backward, and the block 2 rotates counterclockwise, so that the end is lower than the inclined surface of the shovel head 1. At this time, the front end of the frame body 4 is extended into the bottom of the fruit box, and the hydraulic motor 12 is started to move the chain 6 backward, driving the fruit box to move along the long beam of the frame body to the limit frame 9. When the hydraulic cylinder 15 is pushed out, the lifting shaft 20 rotates upward around the wheel shaft 22, and the lifting shaft 20 will lift the frame body 4, so that the long beam of the frame body 4 is in a horizontal state, and the fruit box is laid flat, so that four fruit boxes are loaded continuously. When the hydraulic cylinder 15 is pushed out, the linkage plate 17 will also move forward, so that the block lever 23 is pushed forward, the block 2 rotates clockwise, and the head of the block is lifted to clamp the fruit box to prevent the fruit box from sliding off the frame during transportation. After the fruit box filled with fruits is transported to the designated location, the hydraulic cylinder 15 is retracted, the front end of the frame lands, and the block falls, and the reverse hydraulic motor 12 moves the chain in the opposite direction, unloading the fruit box on the ground, thereby realizing automatic loading and unloading of the fruit box.

[0021] The orchard fruit box loading and unloading transport vehicle uses a tractor or the like as a power traction, automatically loads the fruit boxes onto the vehicle frame, then directly transports the fruit boxes to a designated location, and automatically unloads the fruit boxes, which is highly efficient, saves time and effort, and is suitable for picking in large orchards.
