DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-Figure 8 As shown, the utility model provides the following technical solutions:
[0026] A telescopic orchard agricultural ladder comprises a ladder body 2 for people to climb, and support members 1 are installed on both symmetrical sides of the ladder body 2;
[0027] The support member 1 includes a first connecting tube 13, which has a through first connecting groove 14 along its own axis, and a supporting foot 12 is slidably connected inside the first connecting groove 14. A connecting member 4 for connecting to a fruit tree is provided on the top of the ladder body 2. A first side frame 15 is fixedly connected to one side of the first connecting tube 13, and a first hook 16 is rotatably connected inside the first side frame 15. A first return spring 17 is provided between the first side frame 15 and the first hook 16. One end of the first hook 16 moves through the first connecting tube 13 and the supporting foot 12, and a first through hole matching the first hook 16 is formed between the first connecting tube 13 and the supporting foot 12.
[0028] The ladder body 2 is placed on one side of the fruit tree, and the ladder body 2 is supported by the supporting foot 12 and the first connecting tube 13. The ladder body 2 is used to assist the personnel in climbing to a high place, so that the personnel can move to a high place to perform operations such as pruning branches or picking fruits.
[0029] In addition, in the present invention, after the support legs 12 are placed, in order to make the device more stable when used, Figure 1-Figure 2 , Figure 5 As shown, the bottom of the supporting foot 12 is fixedly connected to the bottom plate 11 .
[0030] Furthermore, in order to increase the strength of the ladder body 2, as Figure 1-Figure 4 As shown, a reinforcement member 3 is provided on one side of the ladder body 2;
[0031] The reinforcement member 3 is located between the two first connecting pipes 13 .
[0032] In this embodiment, when a person uses the ladder body 2 , the strength of the ladder body 2 is increased by the reinforcement member 3 , so that the ladder body 2 is more stable when in use.
[0033] Specifically, in one embodiment, regarding the above-mentioned connecting member 4:
[0034] like Figure 1 , Figure 2 , Figure 6 As shown, the connecting member 4 includes a second connecting tube 45, and the second connecting tube 45 is provided with a through-type second connecting groove 44 along its own axis, and a hook 41 is slidably connected inside the second connecting groove 44, and the second connecting tube 45 is fixedly connected to the second side frame 43 on the circumference, and the second hook 42 is rotatably connected inside the second side frame 43, and a second return spring 46 is arranged between the inside of the second side frame 43 and the second hook 42, and one end of the second hook 42 moves to pass through the second connecting tube 45 and the hook 41, and a second through hole matching the second hook 42 is formed between the second connecting tube 45 and the hook 41.
[0035] In this embodiment, when the person moves the ladder body 2 to the vicinity of the fruit tree, the person presses the second hook 42 to rotate the second hook 42 around the second side frame 43, and then inserts the hook 41 into the second connecting groove 44 on the second connecting pipe 45 until the hook 41 and the second through hole on the second connecting pipe 45 coincide with each other, and then releases the second hook 42, and resets it by the second reset spring 46, so that the second hook 42 is rotated back, so that one end of the second hook 42 is inserted between the second connecting pipe 45 and the hook 41, and then the hook 41 is fixed, and the hanging rod 45 is fixed. After being fixed on the second connecting pipe 45, the ladder body 2 is placed on one side of the fruit tree and connected to the fruit tree through the hook 41, so that the ladder body 2 is placed stably, and the ladder body 2 is supported by the supporting legs 12 and the first connecting pipe 13. The ladder body 2 assists personnel to climb to a high place, so that the personnel can move to a high place to perform operations such as pruning branches and picking fruits of fruit trees. When the personnel need to transport the device, they only need to press the second hook 42 to separate the second hook 42 from the second through hole, and then the hook 41 can be pulled out, so that the device is easy to transport.
[0036] Specifically, in one embodiment, regarding the ladder body 2:
[0037] like Figure 1 , Figure 2 , Figure 6 As shown, the ladder body 2 includes two symmetrically arranged main ladder rods 21 , and a plurality of auxiliary ladder rods 22 are equidistantly arranged between the two main ladder rods 21 .
[0038] In this embodiment, after the personnel move the ladder body 2 to the vicinity of the fruit tree, the main ladder rod 21 and the auxiliary ladder rod 22 cooperate to facilitate the personnel to climb the slope.
[0039] Furthermore, in order to increase the strength between the main ladder rod 21 and the bottom reinforcement rib 23, as shown in FIG. Figure 1-Figure 4 As shown, a reinforcing rib 23 is fixedly connected to one side between the two main ladder rods 21 , and the top free end of the reinforcing rib 23 is fixedly connected to the lowermost auxiliary ladder rod 22 .
[0040] In this embodiment, when a person climbs up through the main ladder rod 21 and the auxiliary ladder rod 22, the strength of the device is increased by the reinforcing ribs 23, so that the device is more stable when in use.
[0041] Specifically, in one embodiment, regarding the reinforcement member 3:
[0042] like Figure 1-Figure 4 As shown, the reinforcement member 3 includes two symmetrical reinforcement main rods 31, and the two reinforcement main rods 31 are respectively fixedly connected to one side of the two main ladder rods 21, and a plurality of reinforcement secondary rods 32 are fixedly connected between the two reinforcement main rods 31, and the free ends of the reinforcement secondary rods 32 are fixedly connected to the secondary ladder rods 22, and the reinforcement secondary rods 32 are matched one by one with the secondary ladder rods 22.
[0043] In this embodiment, when a person uses the device, the connection strength between the main ladder rod 21 and the auxiliary ladder rod 22 is increased by strengthening the main rod 31 and strengthening the auxiliary rod 32, so that the device is more stable when used.
[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
