Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude fruit picking, in particular to a litchi high-altitude fruit picking branch shear structure. Background Art

[0002] Lychee is a tropical fruit that is sweet and juicy and is commonly found in Asian countries. Lychee aerial fruit picking shears are usually designed as a tool specifically for picking lychee fruits at higher altitudes. It has a telescopic or foldable long pole structure to adapt to fruit tree branches at different heights, ensuring that operators can complete high-altitude pruning and harvesting work on the ground.

[0003] The existing method of picking lychees is to pick lychees through a high-altitude picker, which is usually composed of a telescopic rod, a clamp, a collection frame and a pair of scissors. The collection frame is usually of semi-open design. During the picking process, lychees will fall into the collection frame. When the collection frame is full, the telescopic rod will descend and the lychees will easily slip from the collection frame, causing damage to the lychees. At the same time, it is also easy to hit the operator, causing injury to the operator.

[0004] Therefore, it is necessary to design a lychee high-altitude fruit branch picking shear structure that can tighten the collection bag to prevent lychees from falling and reduce damage to lychees, while preventing lychees from accidentally falling and causing injuries to operators, thereby reducing the risk of injury to operators. Summary of the invention

[0005] In order to overcome the shortcomings of the existing high-altitude pickers that the collecting frame is usually of semi-open design, during the descent of the telescopic rod, lychees are easy to slip from the collecting frame, causing damage to the lychees, and are also easy to hit the operators, causing injuries to the operators. The utility model provides a lychee high-altitude fruit picking branch shear structure which can tighten the collecting bag to prevent lychees from falling and reduce the damage to the lychees, while preventing lychees from accidentally falling and causing injuries to the operators, thereby reducing the risk of injuries to the operators.

[0006] A high-altitude lychee fruit-picking branch shear structure comprises an electric lifting rod, a cutting knife, scissors, a mounting block, a rotating frame, a winding wheel, a first pull rope, a limiting mechanism and a collecting mechanism, wherein the cutting knife is connected to the top of the telescopic end of the electric lifting rod, the scissors are rotatably connected to the front side of the telescopic end of the electric lifting rod, the cutting knife cooperates with the scissors, the mounting block is connected to the middle part of the fixed end of the electric lifting rod, the rotating frame is rotatably connected to the mounting block, the winding wheel is rotatably connected to the rotating frame, a first pull rope is wound between the winding wheel and the scissors, a limiting mechanism for limiting the rotation of the winding wheel is provided on the front side of the rotating frame, and a collecting mechanism for collecting lychees is provided on the electric lifting rod.

[0007] Optionally, the cutting knife and the scissors are both made of stainless steel, which has good corrosion resistance and durability.

[0008] Optionally, the limiting mechanism includes a limiting rod and a telescopic spring, the limiting rod is slidably connected to the front side of the rotating frame, the limiting rod is snap-fitted with the winding wheel, and a telescopic spring is connected between the limiting rod and the rotating frame.

[0009] Optionally, a handle is also included, and the front side of the limiting rod is connected to the handle.

[0010] Optionally, the collecting mechanism includes a supporting frame, a telescopic rod, a fixed frame, a connecting frame, a collecting frame, a collecting bag and a second pull rope. The lower part of the fixed end of the electric lifting rod is connected to the supporting frame, the front and rear sides of the right part of the supporting frame are connected to the telescopic rod, the fixed frame is connected between the tops of the telescopic ends of the telescopic rods, the fixed frame is connected to the telescopic ends of the electric lifting rods, the upper parts of the telescopic ends of the telescopic rods are connected to connecting frames, and the collecting frames are connected between the connecting frames. A collecting bag is placed on the collecting frame, the collecting bag is provided with holes, the second pull rope is passed through the holes on the top of the collecting bag, and the second pull rope enters from one side and exits from the other side.

[0011] Optionally, a pull ring is provided on the second pull rope.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model cooperates with the cutting knife by rotating the scissors to cut the lychees, so that the lychees fall into the collecting bag. When the collecting bag is full, the second pull rope is pulled by the pull ring to tighten the collecting bag, thereby preventing the lychees from falling and reducing the damage to the lychees. At the same time, it prevents the lychees from accidentally falling and causing injuries to the operators, thereby reducing the risk of injuries to the operators.

[0013] 2. The utility model is lifted up by the electric lifting rod, which drives the telescopic rod to extend, and then drives the collecting frame to move upward. After moving to a suitable height, the handle is released, the telescopic spring rebounds, the limiting rod moves back to the original position and engages with the winding wheel, thereby fixing the winding wheel to prevent the winding wheel from rotating and causing the cutting knife and scissors to move and affect litchi picking, thereby improving the efficiency of litchi picking.

The winding wheel 6 is rotatably connected to the rotating frame 5, and a first pull rope 7 is wound between the winding wheel 6 and the scissors 3. A limiting mechanism 8 for limiting the rotation of the winding wheel 6 is provided on the front side of the rotating frame 5, and a collecting mechanism 9 for collecting litchi is provided on the electric lifting rod 1.

[0021] like Figure 1 and Figure 3 As shown, the limiting mechanism 8 includes a limiting rod 81, a handle 82 and a telescopic spring 83. The limiting rod 81 is slidably connected to the front side of the rotating frame 5. The limiting rod 81 is snap-fitted with the winding wheel 6. The handle 82 is connected to the front side of the limiting rod 81 to facilitate hand-holding and pulling the limiting rod 81.
