Description

Technical Field

[0001] This utility model relates to the field of plant pruning technology, and in particular to a pumpkin vine length-limiting pruning device. Background Technology

[0002] As a widely cultivated economic crop, the growth status of pumpkin vines directly affects the yield and quality of pumpkins. During the growth process of pumpkins, in order to control the vegetative growth of the plant, promote reproductive growth, and increase the fruit setting rate and fruit size, it is necessary to prune and top the vines regularly, that is, limit the length of the vines.

[0003] Currently, traditional manual scissors or sickles are simple in structure and inexpensive. However, in practice, when dealing with vines that are high up or deep in the ground, operators need to bend over significantly or use ladders or other auxiliary tools. This not only results in high labor intensity and low work efficiency but also poses certain safety hazards. In addition, plant sap will adhere to the scissors after pruning. If it is not cleaned and disinfected in time, it can easily cause cross-infection of pathogens during continuous operation, leading to plant diseases.

[0004] Long-handled manual pruning shears, with their extended handles or levers, have solved the problem of pruning vines at heights and in distant places to some extent. However, their cutting heads are usually controlled by complex linkages or pull-wire mechanisms, making them cumbersome and prone to malfunction after prolonged use. More importantly, these tools do not take into account the cleaning and disinfection of the blades. After use, the sharp blades are exposed, which can easily cut people or damage other items when stored or carried, resulting in poor safety.

[0005] Electric or pneumatic pruning equipment is highly automated and efficient, but it generally suffers from complex structure, heavy weight, high cost, and requires external energy supply (batteries or air pumps), making it unsuitable for all field environments. Utility Model Content

[0006] The purpose of this invention is to provide a pumpkin vine length limiting pruning device that is simple in structure, easy to use, highly safe, and capable of cleaning and disinfecting the blade.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a pumpkin vine length limiting pruning device, including a handle 10, a connecting rod 11, a pruning component, a driving component, and a drying component.

[0020] The handle 10 is the part held by the operator, and one end of it has an integrally formed threaded rod 101, which is used to connect with the connecting rod 11 by threads. This design allows the handle 10 and the connecting rod 11 to be easily disassembled and assembled.

[0021] The connecting rod 11 has a hollow structure. One end of the connecting rod 11 has an internal thread that mates with the threaded rod 101 for connecting the handle 10. The other end of the connecting rod 11 has a threaded groove for installing the trimming component. The interior of the connecting rod 11 is divided into spaces for drying and storage functions, and the outer ring is equipped with a drive component. In order to meet the trimming needs of different heights, connecting rods 11 of different lengths can be replaced, which improves the applicability of the device.

[0022] The trimming assembly is the core component for performing the cutting function. The trimming assembly includes a mounting rod 12, one side of which is threaded and can be screwed into and fixed in the threaded groove of the connecting rod 11, achieving a stable and detachable connection. The other end of the mounting rod 12 is integrally formed with a fixed cutter head 13. A movable cutter head 14 is rotatably mounted on the fixed cutter head 13 via a rotating shaft. In the initial state, the movable cutter head 14 and the fixed cutter head 13 are in an open state. When the movable cutter head 14 rotates around the fixed cutter head 13 to close, the cutting of the pumpkin vine can be completed.

[0023] The drive assembly is used to drive the trimming assembly. The drive assembly includes two rectangular plates 15 arranged in parallel. These two rectangular plates 15 are fixed to the outer ring of the connecting rod 11 by welding or bolts. Between the two rectangular plates 15, a rotating plate 16 is rotatably installed. One end of the rotating plate 16 is connected to the movable cutter head 14 by a high-strength connecting rope 17. When the operator rotates the rotating plate 16 by hand, the connecting rope 17 is tightened, thereby pulling the movable cutter head 14 to move and close in the direction of the fixed cutter head 13, realizing the shearing action. After the rotating plate 16 is released, the movable cutter head 14 can automatically reset and open under the action of the return spring (not shown in the figure).

[0024] The drying assembly is located inside the connecting rod 11 and is used to dry and disinfect the trimmed blade. The internal space of the connecting rod 11 is divided into an installation cavity, a drying cavity, and a storage cavity.

[0025] The mounting cavity is located at one end near the trimming assembly, and a miniature drive motor 20 is installed inside. The output shaft of the drive motor 20 extends through the partition to the drying cavity.

[0026] The drying chamber is located in the middle part. The output shaft of the drive motor 20 is fixedly connected to the fan blade 18 inside the drying chamber. At the same time, several electric heating wires or PTC heating elements are fixedly installed on the inner wall of the drying chamber as heating elements 19. An air inlet 111 is opened on the rod wall of the connecting rod 11 to connect the outside and the drying chamber.

[0027] The storage cavity is located at one end near the handle 10, i.e. the open end of the connecting rod 11. The space of the storage cavity is large enough to accommodate the entire disassembled trimming assembly. An air outlet 112 is provided on the partition between the drying cavity and the storage cavity. An exhaust vent 113 is provided on the side wall of the storage cavity near the open end to connect to the outside.

[0028] The handle 10, connecting rod 11, and pruning assembly are all connected by threads, realizing a modular design. Users can quickly replace the connecting rod 11 of different lengths according to the different heights or distances of the vines to be pruned, easily achieving long-distance pruning operations, reducing labor intensity, and improving operational safety without the need for ladders or other auxiliary tools.

[0029] Workflow: The operator holds the handle 10 and aligns the blade of the pruning component with the pumpkin vine that needs to be pruned. Then, the operator uses the other hand to turn or rotate the rotating plate 16 in the drive component. The rotating plate 16, through the tension of the connecting rope 17, drives the movable blade 14 to move closer to the fixed blade 13 to complete the cutting. By changing the connecting rod 11 of different lengths, this device can easily handle vine pruning work of different heights.

[0030] After the operation is completed, remove the handle 10, unscrew the trimming assembly from the threaded groove of the connecting rod 11, and then place the trimming assembly into the storage cavity at the open end of the connecting rod 11. Screw the threaded rod 101 on the handle 10 into the open end of the storage cavity to seal the storage cavity and prevent the blade from being exposed and causing injury.

[0031] When the drying function of the device is activated, the drive motor 20 starts working, driving the fan blades 18 to rotate. At the same time, the heating element 19 is energized to generate heat. External cold air is drawn in through the air inlet 111, and when it passes through the drying chamber, it is accelerated by the fan blades 18 and heated by the heating element 19 to form hot air. The hot air enters the storage chamber through the air outlet 112 to blow and dry the pruning components stored therein. The water vapor and waste heat generated during the drying process are discharged through the air outlet 113. This process can not only quickly dry the cut of the blade and avoid plant diseases caused by moisture, but also the high temperature hot air can play a role in sterilization and disinfection.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
