Description

Technical Field

[0001] This utility model relates to the field of orchard ladder technology, and in particular to a multifunctional orchard ladder. Background Technology

[0002] Orchards, as an important part of agricultural production, undertake key tasks such as fruit planting, management, and harvesting. In the daily operation of an orchard, fruit farmers need to frequently perform a series of agricultural operations, including pruning branches and leaves, thinning flowers and fruits, bagging, harvesting, and pest and disease control. These operations often involve working areas at different heights, from the base of the fruit trees near the ground to the higher canopy, requiring fruit farmers to be able to reach them conveniently and safely to carry out effective work. Therefore, orchard ladders are an indispensable auxiliary tool for fruit farmers in orchards, and their performance and functionality directly affect the fruit farmers' work efficiency, work quality, and personal safety.

[0003] An adjustable orchard ladder, with announcement number CN222701900U, addresses the instability issues of existing ladders during use. It includes a left and right support leg, with vertical support rods fixedly connected to the top of each leg. Multiple upper footrests are evenly fixedly connected between the two vertical support rods. Lower footrests are evenly fixedly connected between the left and right legs. A top footrest is fixedly connected between the top of the left and right legs, and the top footrest is equipped with a support device. Grip claws are fixedly connected to the lower ends of the support device, the left leg, and the right leg. The upper surfaces of the upper, lower, and top footrests are all textured with anti-slip surfaces. A chain controls the angle between the support tubes and the vertical support rods, improving ladder stability. Simultaneously, pins inserted into positioning holes limit the movement of the support columns, preventing slippage.

[0004] The existing orchard ladders mentioned above rely on grippers for support, offering limited functionality and failing to adapt to diverse terrains. Orchards are typically located in mountainous, hilly, and plain areas, often featuring localized depressions or soft soil. Orchard ladders need to be adaptable to these terrains to ensure stable placement and provide a safe working platform for fruit farmers. The current technology, using only a single gripper, cannot accommodate these variations. Soft ground is prone to collapse, and uneven hard ground can cause wobbling, leading to the ladders easily tipping over and failing to meet the needs of fruit farmers. Therefore, improvements are necessary. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional orchard ladder to solve the problem mentioned in the background art that the existing orchard ladders have only one function and cannot be adapted to different terrains and usage environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional orchard ladder, comprising a left support leg, a right support leg, and a footrest, wherein the footrest is evenly connected between the left support leg and the right support leg;

[0007] The top ends of the left and right support legs are connected to a top frame, and two fixing rods are fixed between the top frames. A disassembly assembly is provided on the outside of the top frame, and a side support leg is connected to the bottom of the disassembly assembly. Diagonal rods are fixed on both sides of the side support leg. A telescopic sleeve is sleeved on the lower end of the side support leg, and multiple fixing holes are arranged longitudinally at equal intervals on the telescopic sleeve. A locking mechanism is provided between the telescopic sleeve and the side support leg. The bottom ends of the left and right support legs and the telescopic sleeve are all fixed with bases. Four foot pedals are provided between the left and right support legs. The bottom of the third foot pedal from the bottom is fixed with a support chain. Limiting rods are connected to both sides of the foot pedal.

[0008] Furthermore, the bottom of the left support leg, the right support leg, and the telescopic sleeve are all provided with mounting grooves, and aluminum nuts are welded into the mounting grooves. A grounding screw is inserted into the aluminum nut, and a fixing nut for fixing the grounding screw is threaded onto the grounding screw.

[0009] Furthermore, a mating screw is inserted into the aluminum nut, and a locking nut for fixing the mating screw is threaded to the outside of the mating screw. One end of the mating screw is connected to a universal ball joint, and a universal foot cup is connected to the outside of the universal ball joint.

[0010] Furthermore, a connecting screw is inserted into the aluminum nut, and a movable wheel is connected to the bottom end of the connecting screw. A limiting nut for fixing the connecting screw is threaded to the outside of the connecting screw.

[0011] Furthermore, the disassembly assembly includes an upper retaining ring and a lower retaining ring fitted onto the top frame. Both the upper and lower retaining rings have three threaded holes evenly spaced, and each threaded hole is threaded with a fixing bolt. One end of the side support leg is welded to the lower retaining ring, and the diagonal bars on both sides of the side support leg are fixedly connected to the bottom of the lower retaining ring.

[0012] Furthermore, hooks are fixed on the side support legs, and the hooks are engaged with the footrests.

[0013] Furthermore, the locking mechanism includes a built-in groove, which is formed on the telescopic sleeve. A telescopic spring is connected inside the built-in groove, and a connecting plate is fixed to one end of the telescopic spring. A fixing pin is fixed to the connecting plate, and one end of the fixing pin passes through the fixing hole.

[0014] Furthermore, the side support rod is rotatably connected to the top frame via an upper and lower clamping ring, and the side support rod extends and retracts in the telescopic sleeve to form a telescopic connection with the telescopic sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the multi-functional orchard ladder can adapt to different usage environments to ensure stability in use, and the inclined support can be disassembled for partial replacement after damage, so as to save usage costs. In addition, the side support can be extended and retracted to adjust the support angle and improve the safety of orchard ladder use.

[0016] By pre-reserving installation slots on the left and right support legs and the telescopic sleeve, and welding bases into the corresponding slots, ground-inserting screws, docking screws, and connecting screws can be installed into the bases. When the orchard ladder is used on muddy ground, the ground-inserting screws can be used to insert the ladder into the ground to improve its stability. The end of the docking screw is fitted with a universal ball joint and universal feet, allowing the left and right support legs to cope with complex terrain, that is, to maintain stable use on pits, bumps, or uneven ground. Then, the end of the connecting screw is fitted with a caster wheel, which allows the orchard ladder to be moved easily to meet different usage environments.

[0017] The side support legs can be installed on the orchard ladder by using the upper and lower clamps to hug the top frame and securing them with multiple fixing bolts. The side support legs can be disassembled later by reversing the operation to achieve partial replacement, thus saving replacement costs in case of damage.

[0018] Press the fixing pin to disengage it from the corresponding fixing hole, and the side support rod can be pulled out to adjust the length of the side support rod and the telescopic sleeve. The side support rod can also be flipped to adjust the support angle. Together with the left and right support legs, it can achieve stable triangular support, improve the overall stability of use, and facilitate fruit farmers' operations. Attached Figure Description

[0031] Please see Figures 1-9 The present invention provides the following technical solution:

[0032] Example 1

[0033] To address the problem of inconvenient replacement and increased operating costs associated with existing orchard ladder inclined support components, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 9 A multi-functional orchard ladder includes a left support leg 1, a right support leg 2, and footrests 3. Footrests 3 are evenly connected between the left support leg 1 and the right support leg 2. A top frame 4 is connected to the top of the left support leg 1 and the right support leg 2, and two fixing rods 5 are fixed between the top frames 4. A disassembly assembly is provided on the outside of the top frame 4, and a side support rod 9 is connected to the bottom of the disassembly assembly. Diagonal rods 901 are fixed on both sides of the side support rod 9. Four footrests 3 are provided between the left support leg 1 and the right support leg 2. The bottom of the third footrest 3 from the bottom is fixed with a support rod. The support chain 18 and the footrest 3 are connected to the limiting rods 13 on both sides. The disassembly components include an upper clamping ring 6 and a lower clamping ring 7 that are sleeved on the top frame 4. The upper clamping ring 6 and the lower clamping ring 7 are each evenly provided with three threaded holes 17, and the threaded holes 17 are each threaded with fixing bolts 8. One end of the side support leg 9 is welded to the lower clamping ring 7. The diagonal bars 901 on both sides of the side support leg 9 are fixedly connected to the bottom of the lower clamping ring 7. The side support leg 9 is fixed with a hook 902, and the hook 902 is snapped onto the footrest 3.

[0034] In this embodiment, the left support leg 1, right support leg 2, multiple footrests 3, and limiting rod 13 work together to form an orchard ladder. Then, the upper retaining ring 6 and lower retaining ring 7 are wrapped around the top frame 4 and fixed with multiple bolts through threaded holes 17, thereby installing the side support leg 9 between the left support leg 1 and right support leg 2 to form a triangular support. Later, the diagonal rod 901 on the side support leg 9 is correspondingly snapped onto the footrest 3 to realize the storage of the side support leg 9. When the side support leg 9 is opened, the diagonal rod 901 can be snapped onto the corresponding chain link on the support chain 18 according to the support angle of the side support leg 9, thereby using the taut support chain 18 to achieve the effect of auxiliary support.

[0035] Example 2

[0036] This embodiment differs from Embodiment 1 in that the length of the side support leg 9 can be adjusted by utilizing the locking mechanism 14, thereby adjusting its support angle. Therefore, the following technical solution is disclosed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3 , Figure 8The lower end of the side support rod 9 is fitted with a telescopic sleeve 10, and the telescopic sleeve 10 is provided with multiple fixing holes 1001 at equal intervals in the longitudinal direction. A locking mechanism 14 is provided between the telescopic sleeve 10 and the side support rod 9. The locking mechanism 14 includes an internal groove 1401, and the internal groove 1401 is opened on the telescopic sleeve 10. A telescopic spring 1402 is connected inside the internal groove 1401, and a connecting plate 1403 is fixed to one end of the telescopic spring 1402. A fixing pin 1404 is fixed on the connecting plate 1403, and one end of the fixing pin 1404 passes through the fixing hole 1001. The side support rod 9 is rotatably connected to the top frame 4 through the upper clamping ring 6 and the lower clamping ring 7. The side support rod 9 extends and retracts in the telescopic sleeve 10 to form a telescopic connection with the telescopic sleeve 10.

[0037] In this embodiment, when in use, press the fixing pin 1404 to move it into the inner groove 1401, and compress the telescopic spring 1402 until the fixing pin 1404 disengages from the fixing hole 1001. Then, pull the side support leg 9 to extend and retract it in the telescopic sleeve 10, thereby adjusting the length of the side support leg 9. Then, using the elastic restoring effect of the telescopic spring 1402, the fixing pin 1404 can be pushed into the corresponding fixing hole 1001, thereby fixing and locking the extended and retracted side support leg 9, so that it can meet the support at different angles during use to adapt to different terrains.
