Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example: An automatic lifting tracked vehicle for an automatic film covering machine for agricultural greenhouses, such as... Figure 1-4As shown, the system mainly includes an action module 1, a lifting module 2, a sliding assembly 3, and two cargo modules 4. The action module 1 adopts a tracked vehicle structure, including a vehicle body and two sets of track wheels symmetrically mounted on both sides of the vehicle body. The track wheels consist of drive wheels, guide wheels, support wheels, and surrounding tracks, ensuring good traction and passability on muddy greenhouse surfaces. The base plate 5 in the lifting module 2 is bolted to the upper surface of the vehicle body. The scissor lift 7 is located between the base plate 5 and the top plate 6, and consists of multiple sets of cross-hinged connecting rods. The cylinder end of the lifting cylinder 8 is hinged to the base plate 5, and the piston rod end is hinged to the lower surface of the top plate 6. The lifting cylinder 8 is driven to extend and retract via a pneumatic control system (conventional technology in the art), thereby causing the scissor lift 7 to extend or retract, thus achieving smooth lifting and lowering of the top plate 6 and the sliding assembly 3 and cargo modules 4 above it.

[0022] like Figure 2-3 As shown, the sliding assembly 3 includes three parallel sliding rods 17 fixedly mounted on the upper surface of the top plate 6. Each sliding rod 17 has a T-shaped groove 18 formed along its length on its upper surface. The bottom of the two sliders 9 is provided with T-shaped fasteners 19 that match the shape of the groove 18, allowing the sliders 9 to slide smoothly along the groove 18 and preventing them from easily detaching. Simultaneously, several staggered reinforcing strips 20 are welded to the bottom of the sliding rods 17, greatly enhancing the bending strength and overall rigidity of the sliding rods 17.

[0023] like Figure 2-3 As shown, each loading module 4 is fixedly mounted on the upper surface of a slider 9. The loading platform includes a main platform 10 and a secondary platform 11. Vertical support frames 13 are fixed on both sides of the main platform 10. The secondary platform 11 is rotatably connected between the two support frames 13 via a pivot. A horizontal support rod 14 is fixed on the support frame 13. The cylinder end of the linkage cylinder 12 is hinged to the support rod 14, and its piston rod end is hinged to the lower surface of the secondary platform 11. When the linkage cylinder 12 extends or retracts, it can drive the secondary platform 11 to rotate around the pivot, forming an angle with the main platform 10 to achieve a retracted state. At the same time, a rod bracket 15 is fixedly mounted on the main platform 10, and a stop rod 16 is erected between the rod brackets 15 of the two loading modules 4. One end of the stop rod 16 is fixedly connected to one of the rod brackets 15 by bolts or welding, and the other end is inserted into the hole of the other rod bracket 15 and is movably connected by pins, snap rings, or screws, which facilitates disassembly or position adjustment. The lever 16 is used to block the coated wheels when carrying goods, preventing them from accidentally slipping off.

[0024] When using, such as Figure 5As shown, based on the wheelbase of the film-covering trolley to be carried (the film-covering trolley is used for automatic film covering in greenhouses), manually push the two load modules 4, adjust the distance between them, and ensure that the linkage cylinder 12 is in the extended state, and that the auxiliary platform 11 and the main platform 10 are on the same plane, that is, in a horizontal state. Install and fix the stop bar 16 between the rod brackets 15;

[0025] Activate Action Module 1 to drive the entire device across the muddy greenhouse floor, moving it to a suitable location near the end of the greenhouse that needs to be covered or the starting position.

[0026] The operating control cylinder 8 extends, driving the scissor arm 7 to extend, smoothly lifting the top plate 6, sliding component 3 and loading module 4. The lifting height should be such that the wheels of the film-covered trolley on the loading platform are slightly higher than the height of the drainage troughs on both sides of the greenhouse.

[0027] The operating control linkage cylinder 12 retracts. The linkage cylinder 12 pulls the auxiliary platform 11 to rotate downwards, so that the auxiliary platform 11 and the main platform 10 form a certain angle. The film-covering trolley located on the main platform 10 and the auxiliary platform 11 loses the support of the platform on one side of the auxiliary platform 11. Under the action of gravity and the rotation of the film-covering trolley wheels, it falls along the inclined surface of the retracted auxiliary platform 11 into the drainage ditch on the same side of the greenhouse, completing the precise placement of the film-covering trolley.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
