Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a gantry-type longitudinal and transverse moving lifting operation platform for multi-layer three-dimensional planting racks. Background Technology

[0002] With the development of modern agricultural technology, multi-layer vertical planting racks have been widely used to save land resources and increase yield per unit area, especially in the industrialized cultivation of edible fungi, where they have become standard equipment. However, the harvesting process still relies heavily on manual labor, resulting in high labor intensity and low efficiency.

[0003] In existing technologies, there are similar lifting platforms or work vehicles for storing and retrieving goods on high-rise shelves, but their direct application in agricultural planting scenarios has many limitations:

[0004] 1. Insufficient flexibility: Large fixed lifting equipment cannot move flexibly and be precisely positioned in the narrow planting rack aisle.

[0005] 2. Lack of functionality: Industrial lifting platforms focus on load-bearing capacity, but their structures are often bulky and lack special designs for agricultural harvesting operations (such as easy access to crops and storage of tools).

[0006] 3. Insufficient space utilization: The passageways between planting racks are usually narrow, and the fixed platform will occupy the passageway space when not in use, affecting the passage of other agricultural equipment.

[0007] 4. High cost: Complex automated equipment is expensive to manufacture and maintain, making it difficult to promote in small and medium-sized agricultural enterprises.

[0008] Therefore, there is an urgent need in this field for a new type of operating platform specifically designed for multi-layer vertical planting. It should be flexible, practical and economical, able to move easily between planting racks, stably rise and fall to any working height, and occupy as little space as possible when not in use. To this end, we propose a gantry-type longitudinal and transverse moving lifting operating platform for multi-layer vertical planting racks to solve the above problems. Utility Model Content

[0046] The small sliding frame 33 can move up and down (Y-axis) along the slide groove 32, and in conjunction with the bidirectional self-locking winch 34, realize the overall lifting function of the small sliding frame 33.

[0047] Furthermore, the small sliding frame 33 includes short columns 331, short crossbeams 332, a movable top beam 333, and a movable bottom beam 334. Two short columns 331 are arranged in parallel. Guide pulleys 39 are fixedly connected to the top and bottom sides of the opposite ends of the two short columns 331. Multiple short crossbeams 332 are fixedly welded between the two short columns 331. The short crossbeams 332 are evenly distributed. The movable top beam 333 is fixedly connected to the top of the two short columns 331. A self-locking winch 34 is fixedly installed at the center of the top of the movable top beam 333.

[0048] Specifically, the foldable pedal 4 includes a pedal 41, a connector 42, and a hinge shaft 43. The connector 42 is fixedly installed on the movable base beam 334, and the hinge shaft 43 is slidably engaged on the connector 42. The hinge shaft 43 is fixedly connected to one end of the pedal 41.

[0049] Furthermore, the pedal 41 includes a support bar 411 and a pedal strip 412. Two support bars 411 are arranged in parallel. One end of each of the two support bars 411 is fixedly connected to a hinge shaft 43. Multiple pedal strips 412 are fixedly welded between the two support bars 411.

[0050] Furthermore, the connector 42 includes mounting holes 421, a limiting plate 422, a hinge slide 423, and a mounting plate 424. The mounting plate 424 has an L-shaped structure. Two mounting holes 421 are provided through one side of the mounting plate 424, and a hinge slide 423 is provided on the other side of the mounting plate 424. The hinge shaft 43 is slidably engaged in the hinge slide 423. One end of the mounting plate 424 is fixedly connected to the limiting plate 422, which has an L-shaped structure.

[0051] By using connector 42 in conjunction with hinge shaft 43, pedal 41 is connected to small sliding frame 33, so that pedal 41 can switch between a horizontally extended working position and a vertically retracted non-working position.

[0052] The working principle and process are as follows:

[0053] 1. Lateral movement (positioning): The operator pushes the gantry frame 1 in the aisle. The pulleys at the top and bottom of the frame roll on the top guide rail 23 and bottom guide rail 24 on the side of the planting rack, easily moving the platform to the target work column.

[0054] 2. Vertical movement (lifting):

[0055] The operator stands on the unfolded foldable footboard 4 and cranks the bidirectional self-locking winch 34 mounted on the small sliding frame 33. The winch winds up the rope, pulling the right fixed pulley 37 and left fixed pulley 38 on the crossbeam 11 through the steel cable 31. Since the right fixed pulley 37 and left fixed pulley 38 are fixed, the reaction force drives the small sliding frame 33, the drive assembly and the operator to rise synchronously. Conversely, the operator cranks the bidirectional self-locking winch 34 in the opposite direction, and the small sliding frame 33 descends smoothly under the action of gravity. The self-locking function of the bidirectional self-locking winch 34 ensures safe hovering.

[0056] 3. Folding the pedal: After the work is completed, lower the platform, step onto the ground, fold the pedal 41 upwards and close it to the column 12, and then push the platform away from the work area.

[0057] Example 3

[0058] The difference between this embodiment and embodiments 1 and 2 is that:

[0059] 1. Drive method replacement: The bidirectional self-locking winch 34 can be replaced with a hand-cranked sprocket and chain mechanism, while the rest of the structure remains the same.

[0060] 2. Replacement of guide mechanism: The guide combination of "slide groove 32 + guide pulley 39" in the longitudinal lifting system 3 can be replaced by linear guide rail slider combination, cylindrical guide rail pulley combination, slide groove roller combination, and the rest of the structure remains the same.

[0061] 3. Power source replacement: The bidirectional self-locking winch 34 can be replaced with a small low-speed motor driven electric winch to achieve electric lifting, while the rest of the structure remains the same.

[0062] 4. Material substitution: The entire portal frame 1 and the small sliding frame 33 can be made of aluminum alloy to achieve lightweighting, while the rest of the structure remains the same.

[0063] 5. Single-track guidance: Refer to Figure 12 The bottom guide rail 24 is removed, and only the top guide rail 23 is retained. The lower pulley 22 or roller of the portal frame 1 is in direct contact with the ground, and the rest of the structure is the same.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
