Description

Technical Field

[0001] This utility model relates to the field of plant protection machinery technology, and in particular to a portable shredder-type pesticide dismantling machine. Background Technology

[0002] With the development of intelligent agriculture, drone-based plant protection has become one of the core methods for pest and disease control in modern agricultural production due to its advantages such as high efficiency, precision, and low reliance on manual labor. In the drone-based plant protection operation process, pesticide preparation is a crucial step: the pilot must first disassemble the pesticide packaging (such as hard plastic bottles, sealed plastic bags, etc.), remove the liquid or powder inside, mix it with water, and then pour it into the drone's tank before spraying can begin. The efficiency and safety of this preliminary step directly affect the continuity of the overall plant protection operation and the pilot's occupational health.

[0003] Currently, pesticide packaging dismantling in the industry still largely relies on manual operation—drone operators handle the packaging by tearing it apart by hand or cutting it with scissors. However, with the large-scale promotion of drone-based plant protection, a single drone operation often needs to handle dozens to hundreds of pesticide packages. The traditional manual dismantling mode has gradually exposed significant pain points: First, the efficiency bottleneck is prominent. Manual dismantling takes a long time per operation, which is difficult to match the high-efficiency requirements of drones for "rapid relocation and continuous operation," easily leading to operational bottlenecks. Second, the safety risks are high. If the pesticide packaging is damaged or the liquid / powder leaks, direct contact with the drone operator's hands can easily cause skin absorption poisoning. Long-term accumulation may even lead to chronic health damage, becoming a major hidden danger restricting safe operation in the industry.

[0004] Existing shredders and crushers on the market are mainly divided into two categories: those for industrial applications, used to crush stone, metal, and concrete, and those designed for high-hardness, large-volume industrial waste. When used for dismantling pesticide packaging, these machines suffer from "excessive power and redundant functions," resulting in high energy consumption, noise, and the risk of pesticide splashing due to over-crushing. The other category consists of lightweight agricultural and forestry equipment designed for crushing branches, straw, and medicinal herbs. These machines are designed for handling fragile, low-strength plant materials, and often fail to tear or jam when dealing with the high hardness and toughness of pesticide packaging (especially rigid plastic bottles), thus failing to meet basic dismantling requirements. Neither type of equipment can accurately meet the "medium strength, controllable tearing" characteristics of pesticide packaging. Utility Model Content

[0005] This application provides a portable shredder-type medicine dismantling machine, which adopts the following technical solution: A portable shredding and dismantling machine includes a housing assembly, a shredding assembly disposed inside the housing assembly, and a drive device that is pulverizedly connected to the shredding assembly. The shredding assembly has a feed inlet at the top and a discharge outlet at the bottom. The shredding assembly is divided into a first shredding group and a second shredding group. The shredding assembly includes a rotating shaft with a plurality of winches mounted on it. The winches are engaged with the rotating shaft. The winches on the first shredding group and the second shredding group are staggered. The rotating shaft is pulverizedly connected to the drive device.

[0006] Preferably, the inner ring of the winch is provided with a plurality of raised ribs, and the rotating shaft is provided with a plurality of snap-fit ​​grooves along the circumference, the snap-fit ​​grooves engaging with the raised ribs.

[0007] Preferably, the driving device includes a drive motor and a reduction gear, the output shaft of the drive motor is provided with transmission teeth, and the drive motor is connected to the reduction gear through the transmission teeth.

[0008] Preferably, the deceleration device includes two drive shafts, which correspond to the first shredding group and the second shredding group respectively. At least two deceleration modules are provided on the drive shafts, and the deceleration modules are alternately arranged on the two drive shafts.

[0009] Preferably, the reduction module includes a large reduction gear and a small reduction gear. The large reduction gear, which is connected to the drive motor, meshes with the transmission gear. The large reduction gear and the small reduction gear rotate synchronously. The small reduction gear meshes with the large reduction gear on another stage of the reduction module.

[0010] Preferably, the rotating shaft is provided with output teeth, one of which is connected to the reduction gear and meshes with the other output tooth for transmission.

[0011] Preferably, the housing assembly includes side plates and a frame, the side plates are located at both ends of the axial direction of the shredding assembly, the frame is disposed on the left and right sides of the shredding assembly, and the frame is connected to the side plates at both ends of the shredding assembly.

[0012] Preferably, the side plate is divided into a first plate and a second plate that are separate from each other. The first plate and the second plate are spliced ​​together to form a complete side plate. The skeleton is divided into two independent skeleton segments along the height. The two adjacent skeleton segments are threaded together. An arc-shaped groove is provided on the skeleton segment. The groove depth of the arc-shaped groove is adapted to the outer diameter of the winch.

[0013] Preferably, protective covers are provided on both sides of the side plate away from the shredding assembly.

[0014] Preferably, the inlet is provided with a feed hopper, which is fixedly connected to the top of the outer casing assembly, and the outlet is provided with a base, which is fixedly connected to the bottom of the outer casing assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The outer shell of this medicine disassembly machine is composed of side plates and a frame. The frame retains only the necessary load-bearing structure, and the side plates only need to close the two ends. The overall weight is much lower than that of a fully enclosed metal shell, making it easier to carry and suitable for use when going out. The frame bears the main load, and the side plates play a protective role. The two have a clear division of labor and do not need to sacrifice volume for strength. Compared with traditional equipment, the whole machine is lighter and more convenient.

[0016] 2. This disassembly machine is designed by dividing the side plate into a first plate and a second plate, which are then spliced ​​together to form a complete side plate. The frame is divided into two independent frame segments. During maintenance or transportation, the disassembly machine can be disassembled into small modules such as single plates and short frame segments, breaking the fixed shape of the whole machine, greatly reducing storage space, making it smaller in size, and allowing users to quickly complete disassembly and maintenance, thus making it more portable.

[0017] 3. This disassembly machine features a quick-release design between the rotating shaft and the winch via raised ribs and slots. The winch can be quickly disassembled and reassembled via raised ribs and slots, eliminating the need to disassemble the rotating shaft. This avoids the difficulty of maintenance caused by disassembling most components when replacing parts. Furthermore, the overall device has no redundant structures; all auxiliary structures retain only essential functions without unnecessary extensions, resulting in a more concise and compact overall design.

[0018] 4. This medicine unpacking machine replaces the traditional method of drone operators manually opening medicine packaging, avoiding irreversible damage to the drone operator, with a higher safety factor, higher efficiency in unpacking medicine packaging, and is more suitable for continuous operation, large-scale farm drone operation, and rapid relocation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] An embodiment of this utility model provides a portable shredding and dismantling medicine machine. Example:

[0026] like Figure 1-3 As shown: A portable shredder for dismantling medicine includes a housing assembly 1, a shredding assembly 2 disposed inside the housing assembly 1, and a drive device 3 driven by the shredding assembly 2. The shredding assembly 2 has an inlet 4 at its top and an outlet 5 at its bottom. The shredding assembly 2 is divided into a first shredding group 201 and a second shredding group 202. The shredding assembly 2 includes a rotating shaft 204 with several winches 203 mounted on it. The winches 203 are engaged with the rotating shaft 204. The winches 203 on the first shredding group 201 and the second shredding group 202 are staggered. The rotating shaft 204 is driven by the drive device 3. This shredding assembly 2 employs a shredding design of the first shredding group 201 and the second shredding group 202, with the two sets of winches 203 staggered. This design significantly improves the shredding efficiency for various types of medicine packaging. The staggered winches 203 also effectively prevent material from leaking through the gaps without being fully shredded, ensuring shredding quality.

[0027] like Figure 8-9 As shown, the inner ring of the winch 203 is surrounded by several raised ribs 6, and the rotating shaft 204 has several engaging grooves 241 along its circumference. The engaging grooves 241 engage with the raised ribs 6. This engaging engagement between the raised ribs 6 and the engaging grooves 241 enables quick installation and removal of the winch 203 on the rotating shaft 204. When a winch 203 needs to be replaced due to wear or damage, it is not necessary to disassemble the entire rotating shaft 204. The old winch 203 can be simply pushed out axially into the engaging grooves 241 to install the new winch 203, greatly simplifying the maintenance process and reducing repair difficulty and time costs. At the same time, this rigid connection method also ensures the stability and transmission reliability of the winch 203 during high-speed rotation, reducing the risk of slippage.

[0028] like Figure 4As shown, the drive unit 3 includes a drive motor 301 and a reduction gear 302. The output shaft of the drive motor 301 has transmission gears 311, and the drive motor 301 is connected to the reduction gear 302 via these gears. By setting two independent drive shafts 321 corresponding to two sets of shredding components respectively, and employing alternating multi-stage reduction modules 322, this dismantling machine achieves reasonable power distribution and smooth transmission. The multi-stage reduction design effectively reduces the high speed output of the drive motor 301, converting it into the low speed and high torque required by the shredding components, meeting the shredding needs of drug packaging with different hardness. The alternating reduction modules 322 help balance the load on the two drive shafts 321, preventing deformation of a single bearing due to excessive torque, thus improving the overall service life and operational stability of the equipment. like Figure 5 As shown: The reduction device 302 includes two drive shafts 321, which correspond to the first shredding group 201 and the second shredding group 202, respectively. At least two stages of reduction modules 322 are provided on each drive shaft 321, and these modules are alternately arranged on the two drive shafts 321. The design of synchronous rotation of the large reduction gear 3221 and the small reduction gear 3222 (e.g., using an integrally formed gear or a rigid coupling) ensures lossless power transmission during reduction, avoiding additional energy consumption and noise caused by relative motion between gears. The step-by-step meshing reduction method provides a larger reduction ratio, resulting in a stronger torque ultimately transmitted to the shredding assembly, ensuring that even thicker or harder pharmaceutical packaging materials can be easily shredded.

[0029] like Figure 6 As shown, the reduction module 322 includes a large reduction gear 3221 and a small reduction gear 3222. The large reduction gear 3221, which is connected to the drive motor 301, meshes with the transmission gear 311. The large reduction gear 3221 and the small reduction gear 3222 rotate synchronously. The small reduction gear 3222 meshes with the large reduction gear 3221 on another stage reduction module 322. The synchronous rotation design of the large reduction gear 3221 and the small reduction gear 3222 ensures lossless power transmission during deceleration and avoids additional energy consumption and noise caused by relative motion between gears. The step-by-step meshing deceleration method can provide a larger reduction ratio, making the torque finally transmitted to the shredding component more powerful, ensuring that even thicker or harder pharmaceutical packaging materials can be easily shredded. The rotating shaft 204 is equipped with output teeth 323, one of which is connected to the reduction gear 3221 and meshes with the other output tooth 323. By setting the meshing output teeth 323 on the rotating shaft 204, synchronous transmission of a single input power to multiple rotating shafts 204 can be achieved. This design ensures the synchronization of the rotational speed and the consistency of the direction of rotation between the first shredding group 201 and the second shredding group 202, avoiding material jamming or equipment overload caused by different rotational speeds or directions of the two shredding components, and further improving the smoothness and stability of the shredding process.

[0030] like Figure 7 As shown: The outer casing assembly 1 includes side plates 101 and a frame 102. The side plates 101 are located at both axial ends of the shredding assembly 2, and the frame 102 is disposed on the left and right sides of the shredding assembly 2, connected to the side plates 101 at both ends of the shredding assembly 2. This combined outer casing structure of side plates 101 and frame 102 balances the structural strength and spatial adaptability of the equipment. The frame 102, as the main load-bearing component, ensures the overall rigidity of the equipment during operation; the side plates 101 serve to enclose and protect the internal components. This modular frame design facilitates dimensional adjustments or component replacements as needed. The overall design is lighter and more convenient and quicker during maintenance and replacement.

[0031] like Figure 10-11 As shown: The side plate 101 is divided into a first plate 111 and a second plate 112, which are separate from each other. The first plate 111 and the second plate 112 are spliced ​​together to form a complete side plate 101. The skeleton 102 is divided into two independent skeleton segments 121 along its height, and the two adjacent skeleton segments 121 are threaded together. The separate design of the first plate 111 and the second plate 112, as well as the segmented threaded connection design of the skeleton segment 121, gives this drug disassembly machine excellent disassembly and adjustability. When deep cleaning, maintenance or replacement of the shredding component 2 is required, the first plate 111, the second plate 112 and the skeleton segment 121 can be quickly disassembled to expose the entire internal structure, providing a large operating space and making it convenient and quick. In addition, the threaded connection of the skeleton segment 121 also allows the height or local size of the outer shell to be adjusted according to actual needs to adapt to the processing requirements of different specifications of drug packaging or the space constraints of different working scenarios. An arc-shaped groove 122 is formed on the frame section 121, and the depth of the groove 122 is adapted to the outer diameter of the winch 203. This matching depth effectively limits the radial movement of the winch 203, preventing radial displacement due to centrifugal force or material impact during high-speed rotation. This ensures the coaxiality of the winch 203 and the rotating shaft 204, thereby guaranteeing shredding accuracy and equipment operational stability. Simultaneously, the arc-shaped groove 122 facilitates the installation, positioning, and alignment of the winch 203.

[0032] Protective covers 103 are provided on both sides of the side plate 101 away from the shredding assembly 2. The protective covers 103 effectively prevent operators from accidentally coming into contact with the high-speed rotating winch 203 or other moving parts during equipment operation, significantly improving the safety of equipment use. At the same time, the protective covers 103 can also block some of the dust or small fragments generated during the shredding process from splashing outwards, improving the working environment.

[0033] A feeding hopper 104 is provided at the inlet 4, and the feeding hopper 104 is fixedly connected to the top of the outer shell assembly 1. A base 105 is provided at the outlet 5, and the base 105 is fixedly connected to the bottom of the outer shell assembly 1. The feeding hopper 104 guides the pharmaceutical packaging material smoothly into the feeding inlet 4, and its funnel-shaped structure helps to concentrate the material and reduce spillage. The base 105 provides stable support for the outlet 5 and can easily collect the shredded material into a designated container or directly discharge it, optimizing the continuity of material handling. The fixed connection between the feeding hopper 104 and the base 105 and the outer shell assembly 1 ensures the structural stability of the overall equipment. In use, this invention involves placing a standard medicine dispensing container below the discharge port 5. A filter screen is added between the container and the discharge port 5 to filter out shredded medicine packaging, preventing it from entering the container. Then, the drive motor 301 is activated, and the medicine to be shredded is fed into the feed hopper 104, entering the shredding assembly 2 to shred the medicine packaging. The shredded medicine falls from the discharge port 5 into the medicine dispensing container. After use, the winch 203 can be easily cleaned, either by rinsing or disassembling for cleaning.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims, not by the foregoing description, and is therefore intended to encompass all variations falling within the meaning and scope of equivalents of the claims. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
