Description

Technical Field

[0001] The utility model relates to the technical field of agricultural tools, in particular to an auxiliary ladder. Background Art

[0002] Fruit trees are edible trees, a general term for perennial plants and their rootstocks that produce edible fruit and seeds. Examples include apple trees, pear trees, citrus trees, apricot trees, and peach trees. Planting fruit trees has become an effective way for farmers to increase their income. Currently, fruit trees are typically grown in mountainous areas. When the fruit ripens, it needs to be harvested. Due to cost constraints, manual harvesting is the most common method.

[0003] At present, the special picking ladder adopts a tripod structure design, which does not need to be set up during picking. However, the support rods of the existing picking ladder are connected to the climbing frame with thin wires, which can only be placed at a maximum angle. Not only is the connection strength insufficient, but the ladder position needs to be readjusted for branches in some special positions, and the operator needs to get down and move the ladder again for adjustment. In the existing technology, the ladder with ladder plates on both sides is relatively large in size and is not easy to place in the orchard. Secondly, it is relatively heavy. Whether it is picking or pruning, the ladder needs to be moved frequently, which increases the labor intensity of the operator. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-3As shown, an auxiliary ladder includes a climbing component, the upper part of which is hinged with a supporting component, the climbing component includes a ladder frame 1, the upper end of the ladder frame 1 is provided with a top frame 2, the top frame 2 is provided with a first pedal 3 and a second pedal 4, the supporting component includes a support rod 5, the upper part of the support rod 5 is connected to the top frame 2 for limited rotation, an auxiliary pedal 6 is provided on the relatively outer side of the support rod 5, the inner end of the auxiliary pedal 6 is fixedly connected to the outer wall of the support rod 5, and auxiliary fixing plates 7 connected to the support rod 5 are provided on both sides of the auxiliary pedal 6, the auxiliary fixing plates 7, the auxiliary pedal 6 and the outer wall of the support rod 5 constitute a positioning area for the operator to step on.

[0024] The ladder frame 1 includes ladder bars 8, which are bent and extended downward and outward from the top frame 2. Ribs 9 are provided on the edges of the ladder bars 8. A plurality of ladder treads 10 are spaced apart between the ladder bars 8. A reinforcing plate 11 may be provided at the connection between the ladder treads 10 and the ladder bars 8. The reinforcing plate 11 has a triangular cross-section. The bent and extended ladder bars 8 increase the strength of the ladder bars 8 and buffer the downward pressure on the ladder bars 8. The reinforcing plates 11 increase the strength of the connection between the ladder treads 10 and the ladder bars 8. The triangular shape of the reinforcing plates 11 enhances the stability of the connection.

[0025] Positioning plates 12 are installed at the ends of the ladder bars 8 and support bars 5. These plates comprise a plate body, the upper portion of which is fixedly connected to the lower ends of the ladder bars 8 and support bars 5, respectively. Several supporting edges are evenly distributed on the lower portion of the plate body. Positioning plates 12 provide a supporting fulcrum for the ladder bars 8 and support bars 5. The arrangement of the plates increases the contact area between the plates 12 and the ground, thereby reducing the pressure at the contact point and ensuring the stability of the ladder support.

[0026] The top frame 2 includes a frame body with an open end. The first tread 3 is fixedly mounted on the frame body near the opening. The ladder rod 8 is fixedly connected to the lower portion of the frame body at an angle. The open end of the frame body facilitates the fixed installation of the first tread 3. The ladder rod 8 is arranged at an angle to the frame body to facilitate the fixing of the ladder rod 8.

[0027] A non-slip cover 16 is mounted on the frame away from the opening. This cover is equipped with several anti-slip grooves. This cover increases the stability of the frame, preventing operators from slipping. Connecting rods 17 securely connect the cover 16 to the support rod 5. These connecting rods 17 are located on either side of the support rod 5. These rods strengthen the connection between the cover 16 and the support rod 5, ensuring operator safety.

[0028] The support rod 5 includes a main rod 18 and a secondary rod 19. The outer diameter of the main rod 18 is larger than the outer diameter of the secondary rod 19. The upper end of the main rod 18 is rotatably connected to the top frame 2, the lower end of the main rod 18 is fixedly connected to the upper end of the secondary rod 19, and the lower end of the secondary rod 19 is fixedly connected to the positioning plate 12. The support rod 5 adopts the arrangement of the main rod 18 and the secondary rod 19, and the length can be adjusted according to actual conditions.

[0029] Example 2

[0030] The difference between this embodiment and the first embodiment is that: Figure 4 As shown, a mounting plate 15 is provided between the lower portion of the frame and the ladder bar 8. The support rod 5 is rotatably mounted on the mounting plate 15. The mounting plate 15 is provided with two adjustment holes corresponding to the support rod 5. The mounting plate 15 can provide a mounting position for the support rod 5. At the same time, the support rod 5 can be adjusted according to actual conditions by adjusting the adjustment holes.

[0031] Example 3

[0032] The difference between this embodiment and the first embodiment is that: Figure 5 As shown, positioning rings 13 are provided on opposite inner sides of the ladder plate 10. The positioning rings 13 are symmetrically arranged along the middle position of the ladder plate 10. Positioning rods 14 are provided on the positioning rings 13. The axial direction of the positioning rods 14 is arranged along the length of the ladder plate 10. The addition of the positioning rings 13 to the ladder plate 10 increases the stepping area for the operator, thereby ensuring the operator's safety.

[0033] The beneficial effect of the utility model is that during normal use, the operator can unfold the climbing component and the supporting component, and the operator can climb on the climbing component to handle the tree. The highest point can be stepped on the first pedal 3 and the second pedal 4 for processing. When processing branches at the same height but different positions, the operator can climb to the auxiliary pedal 6 through the climbing component, and then process the branches at the same height but different positions. There is no need to change the position of the ladder for adjustment, which reduces the labor intensity of the workers and greatly increases the safety of people on the ladder, thereby realizing operation of fruit trees from multiple angles.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
