Description

Technical Field

[0001] This invention relates to the agricultural field, specifically to a telescopic jujube harvesting device. Background Technology

[0002] Jujubes are one of the most common fruits. Since jujubes grow on trees, it is inconvenient to harvest them manually. Workers need to use tools to pick them from the trees, so jujube harvesting equipment is essential.

[0003] The jujube harvesting device works by hooking a hook onto a tree branch and pulling it down to collect the jujubes as they fall to the ground.

[0004] However, current jujube picking devices are not convenient to clamp the hooks to the branches, resulting in incomplete harvesting. Summary of the Invention

[0005] To solve the above-mentioned technical problems, a telescopic jujube picking device is provided. This technical solution solves the problem mentioned in the background technology that it is inconvenient to form a clamp between the hook and the tree branch, which leads to incomplete harvesting when picking jujubes.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A telescopic jujube harvesting device includes a first rod, a second rod, and a third rod. The first rod and the second rod are slidably connected, and the second rod and the third rod are slidably connected. A first connecting rod is provided at the top and bottom of the outer side of the second rod, and a second connecting rod is provided at the top and bottom of the outer side of the third rod. A vertical rod is fixed to the top of the third rod, a horizontal rod is fixed to the top of one side of the vertical rod, a rotating rod is rotatably connected to one side of the horizontal rod, and a squeezing rod is fixed to the bottom of one side of the rotating rod.

[0008] Preferably, the vertical rod has a slot inside, the slot cooperates with the rotating rod, and a spring is installed at the contact position between the rotating rod and the horizontal rod.

[0009] Preferably, there are two connecting rods, one first and one second, with friction grooves on the outer top of the first connecting rod and the other outer top of the second connecting rod.

[0010] Preferably, both the first connecting rod and the second connecting rod have threaded grooves on their outer sides, and the top of the inner wall of the first connecting rod and the top of the inner wall of the second connecting rod are provided with threads that cooperate with the threaded grooves.

[0011] Preferably, a collection groove is provided on the outer side of one of the second connecting rods, and the collection groove is slidably connected to the second connecting rod.

[0012] Preferably, a limiting block is provided at the bottom of the outer side of the second connecting rod, and a limiting groove that cooperates with the limiting block is provided at the bottom of the inner wall of the collection tank.

[0013] Compared with the prior art, the present invention provides a telescopic jujube harvesting device, which has the following beneficial effects:

[0014] The second rod is slidably connected to the first rod. Then, rotating the first connecting rod drives the second rod to rotate, so that the connecting rod at the bottom end fits against the top of the inner wall of the first rod. Under the action of the thread, the extension and fixation between the first rod and the second rod are completed. Similarly, the length adjustment between the third rod and the second rod is completed, thus adapting to jujube branches of different heights. By placing the squeezing rod on the branch and pulling it down, the branch pushes the squeezing rod to rotate outward. Then, the branch enters the bottom of the crossbar, and under the action of the spring, the rotating rod quickly returns to its original position. The rotating rod, together with the crossbar, squeezes the branch. Then, it continues to pull downward, making it easy to pull the jujubes off the branch. Attached Figure Description

[0020] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Example 1

[0022] Please refer to Figures 1-3As shown, a telescopic jujube picking device includes a first rod 1, a second rod 2, and a third rod 3. The first rod 1 and the second rod 2 are slidably connected, and the second rod 2 and the third rod 3 are slidably connected. The top and bottom of the outer side of the second rod 2 are connected by a first connecting rod 4, and the top and bottom of the outer side of the third rod 3 are provided with a second connecting rod 6. The top of the third rod 3 is fixed with a vertical rod 8, the top of one side of the vertical rod 8 is fixed with a horizontal rod 10, one side of the horizontal rod 10 is rotatably connected with a rotating rod 11, and the bottom of one side of the rotating rod 11 is fixed with a squeezing rod 12.

[0023] In this embodiment, the length of the whole is adjusted by sliding the connection between the first rod 1, the second rod 2 and the third rod 3 to adapt to the height of the branch. After the squeezing rod 12 is pushed above the branch, it is pulled down. The branch gradually pushes the squeezing rod 12, and the squeezing rod 12 drives the rotating rod 11 to rotate. After the rotating rod 11 rotates away from the slot 9, the branch enters the lower part of the horizontal bar 10. At this time, the rotating rod 11 resets and presses the branch into the middle position between the rotating rod 11 and the horizontal bar 10. Then, the whole is pulled down continuously to make the jujube on the branch fall.

[0024] Example 2

[0025] Please refer to Figure 3 As shown, the vertical rod 8 has a slot 9 inside, which cooperates with the rotating rod 11. A spring is installed at the contact position between the rotating rod 11 and the horizontal rod 10.

[0026] In this embodiment, the slot 9 facilitates the rotation of the rotating rod 11 into the slot, so that a clamping cavity is formed between the rotating rod 11, the horizontal bar 10 and the vertical bar 8 to clamp the tree branch, and the spring facilitates the rotation of the rotating rod 11 to return to its original position.

[0027] Example 3

[0028] Please refer to Figure 1 and Figure 2 As shown, there are two first connecting rods 4 and two second connecting rods 6. The top of the outer side of one first connecting rod 4 and the top of the outer side of one second connecting rod 6 are provided with friction diagonal lines 7. The outer side of both the first connecting rod 4 and the second connecting rod 6 is provided with threaded grooves. The top of the inner wall of the first connecting rod 4 and the top of the inner wall of the second connecting rod 6 are provided with threads that cooperate with the threaded grooves.

[0029] In this embodiment, the friction groove 7 facilitates manual rotation of the first connecting rod 4 and the second connecting rod 6, and the screw groove and thread cooperate with each other to facilitate the fixing between the first rod 1 and the second rod 2, and the connection and fixing between the second rod 2 and the third rod 3, thereby improving the stability of the overall length adjustment.

[0030] Example 4

[0031] Please refer to Figure 1 and Figure 2 As shown, a collection groove 5 is provided on the outer side of a second connecting rod 6. The collection groove 5 is slidably connected to the second connecting rod 6. A limiting block is provided at the bottom of the outer side of the second connecting rod 6. A limiting groove that cooperates with the limiting block is provided at the bottom of the inner wall of the collection groove 5.

[0032] In this embodiment, the collection trough 5 facilitates the collection of falling jujubes. The limiting block and the limiting trough cooperate with each other to facilitate the disassembly of the collection trough 5, thereby making it convenient to collect the jujubes inside the collection trough 5.
