Description

Technical Field

[0001] The utility model relates to the technical field of fruit picking devices, and in particular to a foldable fruit picking and lifting device. Background Art

[0002] Fruit picking is a common activity in agricultural production and daily life, especially in orchard management and fruit harvest season. However, traditional fruit picking methods have many limitations, especially when it comes to picking fruits at high altitudes. Currently, there are three common picking methods:

[0003] First, directly climb up the fruit tree to pick: Although this method can directly contact the fruit, it is not only laborious but also has great safety hazards when operating on tall fruit trees. During the climbing process, people are prone to lose balance, resulting in falls or other injuries; Second, use ladders to assist in picking: Building a ladder under the tree is another common means of picking, but the height of the ladder is limited. For fruits at higher places, it is necessary to constantly adjust the position of the ladder or use a higher ladder, which is not only time-consuming and labor-intensive, but also the process of frequently moving the ladder also poses safety risks. In orchards, especially in places with complex terrain or narrow space, the use of ladders is more restricted; Third, use tools to assist in picking. By using tools such as high-branch shears to pick fruits at high places, this method is safer and more flexible than the above two methods, but there are still problems such as limited tool length, inconvenient use and difficult storage. These problems will have a negative impact on picking efficiency, thereby causing inconvenience to fruit farmers.

[0004] Therefore, in view of the above problems, there is an urgent need to design a foldable fruit picking and lifting device to facilitate fruit farmers' picking, while taking into account the convenience of placement and height adjustability to solve the limitations of the current picking method. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a foldable fruit picking and lifting device to facilitate fruit farmers' picking, while taking into account the convenience of placement and the adjustability of height to solve the limitations of the current picking method.

[0006] The technical solution is: a foldable fruit picking and lifting device, including an electric telescopic rod, a corrugated sleeve, an armrest, a first connecting frame, a guide rail, a slider, a second connecting frame, a positioning ring and an electric scissors. A corrugated sleeve is provided on the outer shell of the electric telescopic rod, and an armrest is provided on the corrugated sleeve. A first connecting frame is provided on the telescopic end of the electric telescopic rod, guide rails are laterally provided on both sides of the top of the first connecting frame, sliders are slidably provided in the sliding grooves of the two guide rails, a second connecting frame is rotatably provided between the two sliders, the lower end of the second connecting frame is slidably matched with the first connecting frame, a positioning ring is provided on the top right side of the second connecting frame, and an electric scissors with an opening facing the positioning ring are provided on the top of the second connecting frame.

[0007] Furthermore, it also includes a clamping frame and a first elastic member, positioning grooves are provided on both sides of the lower part of the second connecting frame, and the tops of the two guide rails are slidably provided with clamping frames. The two clamping frames are in a relative sliding state, and a first elastic member is provided between the clamping frame and the adjacent guide rails, and the facing ends of the two clamping frames are respectively clamped with the adjacent positioning grooves.

[0008] Furthermore, it also includes guide sleeves, screws and clamps. At least two guide sleeves are arranged at intervals on the outer surface of the positioning ring. Screws are arranged through threads on all guide sleeves. A clamp is arranged at one end of the screw placed inside the positioning ring.

[0009] Furthermore, it also includes a limiting frame and a second elastic member. Slide grooves are opened on both sides of the first connecting frame. The limiting frames are slidably arranged in the two slide grooves. The second elastic member is arranged between the limiting frame and the inner wall of the slide groove on the same side. L-shaped slots are opened on both sides of the second connecting frame, and the L-shaped slots are clamped with the limiting frames on the same side.

[0010] Furthermore, the sliding distance between the second connecting frame and the first connecting frame is smaller than the total length of one guide rail, so as to reserve enough space to allow the second connecting frame to rotate relative to the first connecting frame.

[0011] Furthermore, the second connecting frame can be rotated relative to the first connecting frame and folded until the two are parallel to each other, forming a 180-degree unfolded or folded state.

[0012] The beneficial effects are as follows: 1. The utility model adjusts the height of the entire device through the electric telescopic rod, and cooperates with the electric scissors to complete the picking of fruits. In addition, after the picking is completed, the position of the second connecting frame is adjusted by pushing the slider, and then the second connecting frame is rotated and laid down to achieve a foldable effect, thereby realizing two forms of both height adjustment and convenient folding and storage;

[0013] 2. The utility model fixes the position of the unfolded second connecting frame by means of a positioning frame, thereby achieving stability of the position of the second connecting frame, and significantly improving the stability of the entire device;

[0014] 3. The utility model stabilizes the position of the second connecting frame after folding by means of the limiting frame and the second elastic member, thereby preventing the second connecting frame from rotating and deviating, thereby achieving a stable position effect.

[0024] like Figure 2 and Figure 3 As shown, it also includes a clamping frame 9 and a first elastic member 10. Positioning grooves 61 are provided on the front and rear sides of the lower part of the second connecting frame 6. The tops of the two guide rails 5 are slidably provided with clamping frames 9. The two clamping frames 9 are in a relatively left-right sliding state. The first elastic member 10 is provided between the clamping frame 9 and the adjacent guide rails 5. In this embodiment, the first elastic member 10 is a spring, and the facing ends of the two clamping frames 9 are respectively engaged with the adjacent positioning grooves 61, so as to fix the position of the second connecting frame 6 after unfolding to avoid unnecessary rotation or sliding.

[0025] like Figure 4 and Figure 5As shown, it also includes a guide sleeve 11, a screw rod 111 and a clamping plate 12. Three guide sleeves 11 are arranged at intervals in the circumferential direction of the outer surface of the positioning ring 7. Screw rods 111 are threadedly provided on the three guide sleeves 11. A clamping plate 12 is arranged at one end of the screw rod 111 placed inside the positioning ring 7.

During the above operation, since the clamping frame 9 is placed in the positioning groove 61, that is, the second connecting frame 6 is clamped on both sides. The frame 9 is in a fixed state, so it will not slide or rotate with the slider 51, and the whole will be in a vertical unfolded state to achieve a shape for fruit picking; when the whole picking is completed, the positioning frame 9 is opened, the first elastic member 10 is deformed, so that the second connecting frame 6 is free from the restriction, and then the slider 51 is pushed to drive the second connecting frame 6 to slide to the right on the guide rail 5, and when the second connecting frame 6 moves to the end of the guide rail 5, it is rotated 180 degrees to knock down the second connecting frame 6, so that it is in a folded state parallel to the first connecting frame 4, and then the limiting frame 14 is pushed to slide on the slide groove 13, and the second elastic member 15 is deformed accordingly, and the right end of the limiting frame 14 slides into the L-shaped slot 16, and then cooperates with the inner wall of the L-shaped slot 16 to clamp the position of the second connecting frame 6 after folding to achieve fixation. In summary, the overall operation process.
