Description

Technical Field

[0001] This utility model relates to the field of pepper harvesting technology, specifically a handheld pepper harvesting machine. Background Technology

[0002] Sichuan pepper, a cooking ingredient with a long history, is drought-resistant and suitable for planting in mountainous and hilly areas, bringing good natural and economic benefits. It can bring high economic income to growers, and the maintenance of Sichuan pepper trees requires little labor, making it suitable for large-scale planting.

[0003] However, Sichuan pepper trees have many thorns that can easily cause injury, so manual harvesting is labor-intensive, inefficient, and harmful to health. Manual harvesting is not suitable for large-scale harvesting operations. Harvesting robots are often limited by terrain, and branches and leaves can obstruct the visual sensors. In most cases, manual secondary harvesting is required to retrieve the fruits that the robot missed. This working method is not ideal.

[0004] A search revealed a handheld pepper harvester disclosed in application number CN120036121A, comprising a housing, a handle, a cutter, a motor, and a crank-rocker mechanism. The handle has a battery, the housing is located at the front end of the handle, and the front end of the housing has fruit-combing teeth. The cutter is located above the fruit-combing teeth. The motor is fixed to the housing. The crank-rocker mechanism includes a crank, a rocker arm, and a connecting rod. The first end of the crank is fixedly connected to the motor output shaft, and the second end of the crank is hinged to the middle section of the connecting rod. The first end of the rocker arm is rotatably connected to the housing, and the second end of the rocker arm is hinged to the first end of the connecting rod. The second end of the connecting rod is fixedly connected to the cutter. This invention reduces the unloaded movement time of the cutter through a pull-cut-push-quick-return motion, resulting in a short unloaded running time and rapid cutter reset, thereby improving harvesting efficiency.

[0005] However, in the aforementioned device, the cutter uses a pull-push-rapid return motion to collect peppercorns. When the peppercorns enter the box from the starting position of the cutter, i.e., above the "pull" position, the four-stage motion cannot effectively collect this portion of peppercorns. Furthermore, the device relies on motor drive and crank-rocker transmission, but these structures are not protected. When entering dense peppercorn forests to harvest peppercorns, branches and leaves may damage the motor and crank-rocker structure, causing the device to jam and malfunction. At the same time, the peppercorns harvested by this device are accompanied by a large number of branches and leaves, requiring a significant amount of manpower to remove the branches and leaves after harvesting.

[0006] A search revealed that application number CN110226411B discloses a pepper-separating device with clamping force, comprising a clamping device, a support, a separating roller assembly, and separating blades. The clamping device is positioned above the separating roller assembly and connected to a pepper-harvesting machine. The support is fixedly installed inside the pepper-harvesting machine, and the separating roller assembly is rotatably connected to the support. Multiple separating blades are fixedly installed on the separating roller assembly, with adjustable angles. This invention uses a motor drive and utilizes the combined action of the clamping cap and the separating roller assembly to separate pepper berries from pepper spikes. Multiple separating blades cycle, mimicking a "pinching" action, allowing the pepper stalks to smoothly enter the grooves of the comb teeth without missing any pepper berries. This avoids peppers getting stuck on the blades, and the entire harvesting process only requires one-handed operation, effectively preventing machine malfunctions, improving harvesting efficiency, and significantly enhancing harvesting comfort.

[0007] However, the aforementioned devices are mostly operated with one hand, are small in size, require frequent replacement of storage bags, and are limited in size, resulting in a limited area that can be harvested each time, leading to less than ideal harvesting efficiency. Moreover, the short body of the machine still poses a risk of cuts to harvesters from the thorns of the pepper trees. In addition, the device imitates the "pinching" action by having the harvester press the reset device with their hand to lower the cap. After working for a period of time, the harvester may become exhausted due to the need to repeatedly press the reset device, which could lead to a significant decrease in harvesting efficiency.

Detailed Implementation

[0035] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0036] Please see Figures 1 to 7 This utility model provides a technical solution:

[0037] A handheld pepper harvester includes: a housing 1, a storage box 6, and a protective shell 7. The housing 1 is hollow inside, with its front and bottom surfaces being open. The storage box 6 is suspended below the housing 1 and is used to store the peppers harvested by the harvesting mechanism. The protective shell 7 is fixed to the outer surface of the housing 1, forming a semi-enclosed structure to protect the drive and transmission components. The harvesting mechanism is located inside the cavity of the housing 1 and includes rollers 2, comb-tooth components 3, and a central shaft 5. The rollers 2 are installed at both ends of the central shaft 5. Several comb-tooth components 3 are arranged circumferentially on the rollers 2. The transmission component drives the central shaft 5 to rotate, and the rotating central shaft 5 drives the rollers 2, which are equipped with several comb-tooth components 3, to rotate, for harvesting the peppers that come into contact with the comb-tooth components 3.

[0038] Specifically, the comb component 3 includes a round tooth comb part 3a, which includes a comb frame 301 and round comb teeth 303a; the central shaft 5 includes a cylindrical shaft body 5a.

[0039] Specifically, small holes 106 are symmetrically opened in the middle of the two side walls of the housing 1, a large threaded hole 201 is opened in the center of the roller 2, and threaded posts 501 matching the large threaded hole 201 are provided at both ends of the central shaft 5. When the roller 2 is fully screwed into the threaded post 501 through the large threaded hole 201, the end face of the threaded post 501 away from the central shaft 5 is flush with the end face of the roller 2 that is not in contact with the central shaft 5.

[0040] Specifically, the roller 2 is a polygonal roller, and the number of comb teeth 3 is equal to the number of sides of the roller 2. The roller 2 has a third threaded hole 202 near each vertex. The comb tooth frame 301 has a fourth threaded hole 302 at the middle of both ends that matches the third threaded hole 202. The comb teeth 3 are fixed to each vertex of the roller 2 by fastening screws that pass through the third threaded hole 202 and the fourth threaded hole 302. The comb teeth of each comb tooth 3 are parallel to the corresponding edge line of the roller 2. At the same time, the comb teeth 3 closest to the front end of the box 1 always point towards the bottom surface of the box 1.

[0041] In this embodiment, after the roller 2 is installed on the threaded post 501, a driven gear 11 is installed at the end of the threaded post 501 away from the shaft of the central shaft 5.

[0042] Specifically, the driven gear 11 has a sixth threaded hole 1101 at its center, and the threaded post 501 has a fifth threaded hole 502 at its center on the end face away from the central shaft 5, which matches the sixth threaded hole 1101. The driven gear 11 is fixed to the end face of the threaded post 501 away from the central shaft 5 by fastening screws that pass through the sixth threaded hole 1101, the small hole 106 on the side wall of the housing, and the fifth threaded hole 502 in succession.

[0043] Specifically, the driven gear 11 is located on the outside of the side wall of the housing 1, and the threaded post 501 is located inside the cavity of the housing 1. The driven gear 11 is fixed on the threaded post 501 by a small hole 106 opened in the side wall of the housing 1.

[0044] Specifically, the size of the small hole 106 can be the same as that of the fifth threaded hole 502 and the sixth threaded hole 1101, so that the driven gear 11 drives the central shaft 5 to rotate through the fastening screw; the size of the small hole 106 can also be slightly larger than that of the fifth threaded hole 502 and the sixth threaded hole 1101, and a bearing matching the size of the fifth threaded hole 502 and the sixth threaded hole 1101 can be installed on the inner wall of the hole to make the driven gear 11 drive the central shaft 5 to rotate more smoothly. In short, as long as the driven gear 11 can drive the central shaft 5 to rotate, it is acceptable.

[0045] Specifically, the direction of rotation of the central shaft 5 is the same as the direction of the tips of the comb teeth in the comb component 3.

[0046] In this embodiment, the harvesting structure is driven by a motor 8 and gear transmission.

[0047] Specifically, the top surface of the housing 1 is provided with a motor frame 101 for fixing the motor 8. The transmission rods 9 are symmetrically installed on both sides of the motor 8, and a transmission gear 10 is installed on the end of the transmission rod 9 that is not connected to the motor 8.

[0048] Specifically, the transmission gear 10 has a seventh threaded hole 1001 at its center. The transmission gear 10 is fixed by a fastening screw that passes through the seventh threaded hole 1001 and penetrates to a certain depth through the center of the end face of the transmission rod 9 before it is installed to the motor 8.

[0049] Specifically, the distance between the transmission gear 10 and the driven gear 11 ensures that they can mesh with each other to achieve gear engagement.

[0050] Specifically, after the motor 8 starts working, it first drives the transmission gear 10 to rotate. The rotation of the transmission gear 10 drives the driven gear 11 to rotate, thereby driving the central shaft 5 to rotate, which in turn drives the rollers 2, which are fixed at both ends of the central shaft 5 and have several comb-tooth components 3 installed, to rotate, so as to carry out the pepper harvesting operation.

[0051] Specifically, during the rotation of the comb tooth component 3, the branches, leaves and fruits of the pepper can be initially separated, reducing the tediousness of the subsequent separation of branches and leaves.

[0052] Specifically, the design of the comb teeth makes the picking process more like a "sweeping" action, which initially separates the branches and leaves of the pepper from the fruit. As the comb tooth component 3 rotates continuously, the peppers that are not located between the teeth are hit by the comb tooth component 3 and change position, so that they are "sweeped" off by the subsequent rotating comb tooth component 3.

[0053] In this embodiment, a first boss 105 for mounting a connecting rod 12 is provided at the center of the top of the housing 1 near the rear end face; both ends of the connecting rod 12 are provided with ear plates 1201 that cooperate with the first boss 105, and the ear plate 1201 on the side of the connecting rod 12 that does not cooperate with the first boss 105 is used to mount a gripping rod 13.

[0054] Specifically, the gripping rod 13 has a second boss 1301 at one end that is exactly the same as the first boss 105, which is used to cooperate with the ear plate 1201 to install the gripping rod 13 to the end of the connecting rod 12 away from the housing 1.

[0055] Specifically, damping elements are provided between the first boss 105 and the ear plate 1201 at one end that mates with it, and between the second boss 1301 and the ear plate 1201 at the other end that mates with it. The two sets of damping elements are similar to two joints on a human arm, which allows the box 1, the connecting rod 12 and the gripping rod 13 to rotate relative to each other to adjust the angle, making it convenient to collect peppercorns from different positions.

[0056] Specifically, the design of the damping element results in significant friction between the first boss 105 and the ear plate 1201 at one end that mates with it, and between the second boss 1301 and the ear plate 1201 at the other end that mates with it. A large amount of force needs to be applied manually to adjust the angle between the housing 1, the connecting rod 12, and the gripping rod 13. After the force is stopped, the housing 1, the connecting rod 12, and the gripping rod 13 maintain the required angle and remain relatively fixed.

[0057] Specifically, the gripping rod 13 has a battery compartment inside to accommodate the battery 14. The battery compartment cover 1303 is hinged to the end face of the gripping rod 13 away from the second protrusion 1301. Due to the complex terrain for picking peppercorns and the large degree of machine shaking, the end face of the gripping rod 13 that is hinged to the battery compartment cover 1303 is also additionally hinged to a fixing plate 1304 to help fix the battery compartment cover 1303, so as to ensure that the battery 14 will not fall off when picking peppercorns.

[0058] Specifically, the fixing plate 1304 and the battery compartment cover 1303 are hinged on different edge lines of the same end face of the gripping rod 13.

[0059] Specifically, when it is necessary to replace the battery 14, first open the fixing plate 1304, then open the battery compartment cover 1303, and slightly tilt the end of the holding rod 13 that is hinged to the battery compartment cover 1303 towards the ground. The battery 14, which has been depleted of power, will slide out due to gravity. After inserting the new battery 14, close the battery compartment cover 1303 and then close the fixing plate 1304. The replacement of the battery 14 is then complete.

[0060] Specifically, a rotary switch 1302 is mounted on the grip rod 13. The rotary switch 1302 is located near the fixed plate 1304. The rotary switch is used to control the start and stop of the motor 8 and its speed.

[0061] Specifically, since the first boss 105 and the ear plate 1201 at one end that mates with it, and the second boss 1301 and the ear plate 1201 at the other end that mates with it, both have wires that transmit electrical energy from the battery 14 to the motor 8, protective sleeves made of rubber or other elastic insulating materials can be installed at these two locations. This will protect the circuit without affecting the relative rotation of the adjustment angle between the housing 1, the connecting rod 12, and the gripping rod 13.

[0062] In this embodiment, the motor 8, transmission gear 10 and driven gear 11 are protected by fixing a protective shell 7 that partially covers the surface of the housing 1.

[0063] Specifically, the protective shell 7 has several second threaded holes 704 on its front and rear faces, and the box body 1 has first threaded holes 104 that match the second threaded holes 704 on its front and rear faces. The protective shell 7 is fixed to the outer surface of the box body 1 by fastening screws that pass through the second threaded holes 704 and the first threaded holes 104.

[0064] Specifically, the bottom and lower half of the front face of the protective shell 7 are open. The lower half of the front face is open to ensure that the harvesting structure inside the box cavity can be fully exposed when the protective shell 7 is installed on the outer surface of the box body 1, and to protect the motor 8 above the box body 1.

[0065] Specifically, the protective shell 7 is slightly wider than the box body 1, so that after the protective shell 7 is installed on the outer surface of the box body 1, it can protect the transmission gear 10 and driven gear 11 on both sides of the box body.

[0066] Specifically, the protective shell 7 has several vertically arranged strip holes 701 on the front and rear faces near the top, several round holes 702 on the top, and a square hole 703 centered on the top close to the rear face, the square hole 703 penetrating the rear face of the protective shell 7 to a certain depth.

[0067] Specifically, the strip-shaped holes 701 are relatively fine and are oriented towards the top surface of the protective shell 7, and the round holes 702 on the top of the protective shell 7 are also relatively fine.

[0068] Specifically, the fine strip-shaped holes 701 and round holes 702 ensure heat dissipation during the operation of the motor 8, while making it difficult for the branches and leaves of the pepper tree to enter the protective shell 7 and cause damage to the motor 8, transmission gear 10 and driven gear 11.

[0069] Specifically, the square hole 703 ensures that the protective shell 7 does not restrict the relative rotation between the housing 1 and the connecting rod 12.

[0070] Specifically, the protective shell 7 is made of materials that combine hardness, transparency and lightweight, such as PVC transparent board or plexiglass, which protect the drive components and transmission components while facilitating the inspection of their operation at any time, and at the same time reducing the weight of the machine.

[0071] In this embodiment, a first protrusion 102 is provided at the center of the bottom of both sides of the box 1 for hanging the storage box 6. The storage box 6 is used to collect the peppercorns harvested by the harvesting structure. The top of the storage box 6 has a hanging ear 601.

[0072] Specifically, since the harvesting structure is located inside the chamber of the box 1, even if the harvested peppercorns are affected by the rotation of the harvesting structure and splash, they will be constrained by the inner wall of the box 1 and finally fall into the storage box 6 suspended below the box 1.

[0073] Specifically, the first protrusion 102 can be used not only to hang the storage box 6, but also to hang storage bags, storage boxes, etc. In short, it can be used to store the peppercorns harvested by the harvesting structure. When these storage items are hung on the first protrusion 102, due to their own weight, the hanging points, such as the hanging ears 601, are in close contact with the first protrusion 102, and the friction between the two is relatively large, making it difficult for the storage items to fall off the first protrusion 102.

[0074] In this embodiment, when harvesting Sichuan peppercorns, the front end of the box 1, which is exposed at the harvesting structure, is aligned with the area where the harvesting operation is to be carried out. The machine is then moved forward so that the Sichuan peppercorn branches 15 enter the harvesting structure. Subsequently, the harvested Sichuan peppercorns 1502 and the thin Sichuan peppercorn branches 1501 that are knocked down together detach from the thick Sichuan peppercorn branches 1503 and fall into the storage box 6. Example

[0075] Please see Figures 8 to 9 This utility model provides a technical solution;

[0076] This embodiment is largely the same as Embodiment 1, with slight differences: the comb component 3 includes a sawtooth comb part 3b, which includes a comb frame 301 and sawtooth comb teeth 303b; the central shaft 5 includes a shaft body 5b with blades and blades 503b arranged axially along the central shaft 5; the two side walls of the housing 1 are symmetrically provided with second protrusions 103 for installing guide teeth 4 near the bottom of the housing 1 and away from the rear end face of the housing 1.

[0077] Specifically, because the comb tooth component 3 uses the serrated comb tooth part 3b, it can pick some pepper varieties that are harder on the branches and are not easy to pick using the round tooth comb tooth part 3a.

[0078] Specifically, the tooth spacing, size, shape, number, and density of each tooth of the guide tooth 4 are the same as those of the serrated comb tooth 303b. This design ensures that the peppercorns diverted by the guide tooth 4 are evenly guided to the tooth spacing of the serrated comb tooth 303b, making it easier for the harvesting structure to pick the peppercorns.

[0079] Specifically, the guide tooth 4 is designed to be detachable and can be removed when not necessary to reduce the weight of the handheld pepper harvester and reduce the burden on the harvesters. The guide tooth 4 and the second protrusion 103 are provided with a damping element. After the guide tooth 4 is installed, the harvesters can adjust the angle of the guide tooth 4 relative to the box 1 according to the specific situation to meet the harvesting needs of peppers in different positions.

[0080] Specifically, because the central shaft 5 rotates continuously, the blades 503b arranged along the central shaft 5 axis on the shaft 5b with blades can crush the pepper branches and leaves that enter the harvesting structure and cause them to eventually flow into the collection box 6, preventing the harvesting structure from getting stuck or even the machine from being damaged.

[0081] Specifically, the blade 503b has the same orientation as the tooth tip of the serrated comb 303b, and both rotate in the same direction and on the same axis.

[0082] All other parts of this utility model not described herein are the same as existing technology, or are known technology, or can be implemented using existing technology, and will not be described in detail here.

[0083] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
