Description

Technical Field

[0001] This invention belongs to the field of chrysanthemum harvesting technology, specifically, it relates to a chrysanthemum harvesting device. Background Technology

[0002] Chrysanthemum is a plant that can clear heat, relieve summer heat, improve eyesight, and nourish the mind. It has certain therapeutic effects on dry mouth, excessive internal heat, and eye irritation, and is one of the main ingredients in mainstream herbal teas on the market. However, chrysanthemums have a short flowering period, and if they are not harvested in time, they will wither and lose their economic value.

[0003] Currently, chrysanthemums are mainly harvested by hand. Chrysanthemum harvesting is time-consuming and requires a lot of manpower, resulting in low harvesting efficiency. There are few chrysanthemum harvesting machines on the market. They are generally harvested by combing with teeth. In the commonly used harvesting devices, the gap between the teeth, i.e. the harvesting gap, is often fixed, which can easily lead to missed harvesting or chrysanthemums being pressed under the teeth during the harvesting process. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a chrysanthemum harvesting device to solve the technical problem mentioned in the background art that the gap between the comb teeth, i.e. the picking gap, is often fixed in the commonly used harvesting devices.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this invention includes:

[0006] A chrysanthemum harvesting device includes a frame, a drive mechanism, a transmission mechanism, a rotating plate assembly, fixed picking comb teeth, movable picking comb teeth, a pushing assembly, and a side baffle.

[0007] The drive mechanism is mounted on the frame, and the transmission mechanism and the rotating plate assembly are rotatably mounted on the frame. The drive mechanism can periodically drive the transmission mechanism to rotate forward and reverse, thereby driving the rotating plate assembly to rotate forward and reverse.

[0008] The fixed picking comb teeth are provided in multiple ways and fixed on the rotating plate assembly. The movable picking comb teeth are provided in multiple ways and slidably provided on the rotating plate assembly. The pushing component is slidably inserted through the rotating plate assembly and connected to each of the movable picking comb teeth in sequence. The side baffle is fixed on the frame and is provided with a guide groove with a slope. The pushing component abuts against the guide groove and moves from a low position to a high position as the rotating plate assembly rotates forward, driving each of the movable picking comb teeth to move toward the fixed picking comb teeth or the rotating plate assembly.

[0009] The pushing assembly includes a sliding rod, a telescopic connector, a support spring, and a stop rod; the sliding rod is slidably mounted on the rotating plate assembly, the movable picking comb teeth are fixed on the sliding rod, the telescopic connector is fixed on the end of the sliding rod away from the rotating plate assembly and is connected to the rotating plate assembly through the support spring, and the stop rod is fixed on the telescopic rod;

[0010] The telescopic connector includes a fixed box, a connecting spring, and a sliding plate. The fixed box is fixed to the sliding rod, and the sliding plate is slidably connected to the fixed box in a vertical manner and connected to the inner bottom surface of the fixed box via the connecting spring. The abutment rod is fixed to the sliding plate. By setting the telescopic connector to have an elastic telescopic range, the abutment rod can move more smoothly within the guide groove.

[0011] Furthermore, the guide groove includes a slope groove and a flat groove; when the pushing component is in the flat groove, the moving picking comb teeth maintain their initial position. The slope groove and the flat groove are connected, and the lowest end of the slope groove and the flat groove are on the same plane. A baffle assembly is rotatably provided on the flat groove, and the baffle assembly is elastic. When the rotating plate assembly rotates forward, the pushing component is guided into the slope groove through the baffle assembly. Before reversing, the rotating plate assembly falls from the slope groove into the flat groove, and slides along the flat groove during reversal, pushing the baffle assembly back to its initial position. That is, the picking gap gradually narrows to its minimum when the picking rotation is lifted, and returns to its maximum value when reversing and lowering, further avoiding the problem of knocking the chrysanthemum off due to the small gap when lowering.

[0012] Furthermore, the baffle assembly includes a baffle body, a baffle shaft, and an elastic connector; the baffle body is rotatably connected to the flat groove via the baffle shaft, and abuts against the slope groove on the side away from the rotating plate assembly via the elastic connector, the elastic connector being disposed in the upper horizontal groove.

[0013] Furthermore, the rotating plate assembly includes a rotating plate body and side leak-proof plates; the baffle assembly is rotatably mounted on the frame, and the rotation of the transmission assembly can drive the rotation of the rotating plate body; the side leak-proof plates are fixed to both sides of the rotating plate body. By setting the side leak-proof plates, the chrysanthemums can be prevented from accidentally slipping off the sides during harvesting.

[0014] Furthermore, the transmission assembly includes a transmission shaft, a gear, a connecting plate, and a slider; the transmission shaft is rotatably connected to the frame, the gear is coaxially fixed on the transmission shaft, and the drive mechanism can drive the gear to rotate forward and reverse; one end of the connecting plate is fixed on the transmission shaft, and the other end is slidably connected to the rotating plate assembly through the slider.

[0015] Furthermore, the driving mechanism includes a driving component, a connecting assembly, and a rack. The driving component is mounted on the frame and connected to the rack via the connecting assembly. The rack is slidably connected to the frame and meshes with the gear. The driving component can drive the rack to perform linear reciprocating motion via the connecting assembly. Driven by the driving component, the rack performs linear reciprocating motion, thereby causing the gear to periodically rotate forward and backward.

[0016] Furthermore, the driving component is a motor, and the connecting assembly includes a connecting rod and a transmission rod; the connecting rod is fixed to the output end of the motor, one end of the transmission rod is hinged to the output end of the motor, and the other end is hinged to the rack.

[0017] Furthermore, the frame is also equipped with a limiting groove, and a collection frame is placed inside the limiting groove. By restricting the position of the collection frame by the limiting groove, the picked chrysanthemums can be made to fall towards the target.

[0018] Compared with the prior art, the advantages of the present invention include:

[0019] During harvesting, the harvesting gaps are gradually reduced from large to small, thereby reducing the possibility that some chrysanthemums may slip out of the harvesting gaps due to excessively large gaps, thus reducing the possibility of missed harvesting.

[0020] After harvesting, the harvesting gaps are gradually widened to reduce the possibility that the chrysanthemums will not be caught in the gaps or will be directly pulled off the plants when the harvesting combs fall due to the small harvesting gaps. Attached Figure Description

[0034] The present invention aims to introduce and explain the structural composition of a chrysanthemum harvesting device and the cooperation relationship between the various components. Unless otherwise specified, the size, material and manufacturing process of each component in the chrysanthemum harvesting device in the present invention can be selected according to specific circumstances, and no special limitations or explanations are made here.

[0035] Furthermore, to provide the public with a better understanding of the present invention, certain specific details are described in detail in the following description of the invention. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0036] Please refer to the following: Figures 1-5 This embodiment provides 1. A chrysanthemum harvesting device, characterized in that: it includes a frame 1, a drive mechanism 2, a transmission mechanism 3, a rotating plate assembly 4, fixed picking comb teeth 5, movable picking comb teeth 6, a pushing assembly 7, and a side baffle 8;

[0037] The drive mechanism 2 is mounted on the frame 1, and the transmission mechanism 3 and the rotating plate assembly 4 are rotatably mounted on the frame 1. The drive mechanism 2 can periodically drive the transmission mechanism 3 to rotate forward and reverse, thereby driving the rotating plate assembly 4 to rotate forward and reverse. Specifically, the forward rotation of the transmission mechanism 3 drives the rotating plate assembly 4 to rotate forward, and the reverse rotation of the transmission mechanism 3 drives the rotating plate assembly 4 to rotate reverse. After the drive mechanism 2 drives the transmission mechanism 3 to rotate forward to a certain angle, it drives the transmission mechanism 3 to rotate reverse and reset, thereby realizing the lifting and lowering of the rotating plate assembly 4. It should also be understood that the frame 1 includes the body and the moving wheels and other mechanisms that drive its movement. There are many detailed descriptions in the prior art, so this application will not repeat them here.

[0038] Multiple fixed picking comb teeth 5 are fixedly mounted on the rotating plate assembly 4. Multiple movable picking comb teeth 6 are slidably mounted on the rotating plate assembly 4. A pushing component 7 is slidably mounted on the rotating plate assembly 4 and connected to each movable picking comb tooth 6 in sequence; that is, each movable picking comb tooth 6 slides as the pushing component 7 slides. A side baffle 8 is fixed on the frame 1 and is provided with a sloped guide groove 81. The pushing component 7 abuts against the guide groove 81 and moves from a lower position to a higher position as the rotating plate assembly 4 rotates forward, driving each movable picking comb tooth 6 to move toward the fixed picking comb teeth 5 or the rotating plate assembly 4.

[0039] In other words, during the forward rotation of the rotating plate assembly 4, the slope of the guide groove 81 causes the pushing component 7 to slide closer to the rotating plate assembly 4, thereby driving the other moving picking combs 6 to slide. This gradually reduces the gap between the moving picking combs 6 and the fixed picking combs 5 or the rotating plate assembly 4 in their direction of movement. Furthermore, due to the elasticity of the pushing component 7, after the rotating plate assembly 4 reverses, the pushing component 7 can drive the moving picking combs 6 to reset. Specifically, in the initial state, the moving picking combs 6 are tightly attached to the rotating plate assembly 4 or the fixed picking combs 5. During forward rotation, the sliding distance of the moving combs 6 towards the adjacent fixed picking combs 5 or the rotating plate assembly 4 is the picking gap for picking chrysanthemums. By reducing the picking gap, the chrysanthemums are picked during rotation. Regarding the connection strength of the side baffle 8, this can be improved by adding reinforcing ribs or other methods, which will not be elaborated upon here.

[0040] The pushing assembly 7 includes a sliding rod 71, a telescopic connector 72, a support spring 73, and an abutment rod 74. The sliding rod 71 is slidably mounted on the rotating plate assembly 4, and the movable picking comb 6 is fixed on the sliding rod 71. The telescopic connector 72 is fixed on the end of the sliding rod 71 away from the rotating plate assembly 4 and is connected to the rotating plate assembly 4 through the support spring 73. The abutment rod 74 is fixed on the telescopic rod. The abutment rod 74 abuts against the guide groove 81 through the support spring 73, and its abutment end preferably has a rounded corner or a spherical surface.

[0041] The telescopic connector 72 includes a fixed box 721, a connecting spring 722, and a sliding plate 723. The fixed box 721 is fixed to the sliding rod 71, and the sliding plate 723 is slidably connected to the fixed box 721 and connected to the inner bottom surface of the fixed box 721 via the connecting spring 722. The abutment rod 74 is fixed to the sliding plate 723. By setting the telescopic connector 72 to have an elastic telescopic range, the abutment rod 74 can move more smoothly within the guide groove 81.

[0042] In this application, the forward rotation of the rotating plate assembly 4 drives the pushing assembly 7 to continuously move from the lower part of the guide groove 81 to the higher part, so that the pushing assembly 7 slides towards the rotating plate assembly 4 during the forward rotation of the rotating assembly, thereby driving each moving picking comb tooth 6 to slide, reducing the distance between the moving picking comb tooth 6 and its opposite fixed picking comb tooth 5 or the rotating plate assembly 4.

[0043] During harvesting, the harvesting gaps are gradually reduced from large to small, thereby reducing the possibility that some chrysanthemums may slip out of the harvesting gaps due to excessively large gaps, thus reducing the possibility of missed harvesting.

[0044] After harvesting, the harvesting gaps are gradually widened to reduce the possibility that the chrysanthemums will not be caught in the gaps or will be directly pulled off the plants when the harvesting combs fall due to the small harvesting gaps.

[0045] In other embodiments, the guide groove 81 includes a slope groove 811 and a flat groove 812; when the pushing component 7 is in the flat groove 812, the picking comb 6 moves to maintain its initial position. The slope groove 811 and the flat groove 812 are connected. The lowest end of the slope groove 811 and the flat groove 812 are on the same plane. A baffle assembly 9 is rotatably provided on the flat groove 812. The baffle assembly 9 is elastic. When the rotating plate assembly 4 rotates forward, the pushing component 7 is guided into the slope groove 811 through the baffle assembly 9. Before reversing, the rotating plate assembly 4 falls from the slope groove 811 into the flat groove 812 and slides along the flat groove 812 during reversal. After pushing the baffle assembly 9, it returns to its initial position.

[0046] Specifically, the flat groove 812 is composed of an arc-shaped groove and an inclined L-shaped groove. The long side of the L-shaped groove is connected to the end of the arc-shaped groove. The highest end of the slope groove 811 is connected to the end of the short side of the L-shaped groove, and the lowest end of the slope groove 811 is connected to the arc-shaped groove. One end of the rotating shaft of the baffle assembly 9 is located on the arc-shaped groove, and the other end is abutted against the slope groove 811 away from the rotating plate assembly 4 by elastic force. This allows the pushing assembly 7 to move on the arc-shaped groove to the baffle assembly 9 when the rotating plate assembly 4 rotates forward. Due to the pull of its own elastic force, the baffle assembly 9 abuts against the slope groove 811. The pushing assembly 7 enters the slope groove 811 along the baffle assembly 9 and falls from the slope groove 811 into the L-shaped groove before the rotating plate assembly 4 reverses. Then, it moves along the L-shaped groove to the arc-shaped groove, pushing the baffle assembly 9 to rotate towards the rotating plate assembly 4 until it is reset. The arc-shaped groove is preferably concentric with the axis of the rotating plate assembly 4, thereby making its initial rotation smoother. It should be understood that the pushing component 7 abuts against the inner bottom surface of the guide groove 81 under the action of its own elastic force, and the plane formed by any three abutment points of the pushing component 7 within the inner bottom surface of the flat groove 812 is coplanar. Through this structure, the moving picking comb 6 can return to the initial distance after rotating and approaching the fixed picking comb 5 or the rotating plate assembly 4. That is, the picking gap gradually narrows to the minimum when the picking is rotated and lifted, and returns to the maximum value when it is reversed and lowered, further avoiding the problem of knocking the chrysanthemum off due to the small gap when lowering.

[0047] In other embodiments, the baffle assembly 9 includes a baffle body 91, a baffle pivot 92, and an elastic connector 93. The baffle body 91 is rotatably connected to the flat groove 812 via the baffle pivot 92, and abuts against the slope groove 811 on the side away from the rotating plate assembly 4 via the elastic connector 93, which is located within the upper horizontal groove 812. Specifically, the baffle pivot 92 is located within the flat groove 812 on the side away from the slope groove 811 and is situated on the extended surface of the slope groove 811. The elastic connector 93 is in a stretched state and is preferably an elastic rope.

[0048] In other embodiments, the rotating plate assembly 4 includes a rotating plate body 41 and side leak-proof plates 42; the baffle assembly 9 is rotatably mounted on the frame 1, and the rotation of the transmission assembly can drive the rotation of the rotating plate body 41; the side leak-proof plates 42 are fixed on both sides of the rotating plate body 41. Preferably, the sliding rod 71 is slidably inserted through the side leak-proof plate 42, and the support spring 73 is in a compressed state located between the telescopic connector 72 and the side leak-proof plate 42. By setting the side leak-proof plates 42, the accidental slippage of chrysanthemums from the side during harvesting can be prevented.

[0049] In other embodiments, the transmission assembly includes a transmission shaft 31, a gear 32, a connecting plate 33, and a slider 34. The transmission shaft 31 is rotatably connected to the frame 1, and the gear 32 is coaxially fixed to the transmission shaft 31. The drive mechanism 2 can drive the gear 32 to rotate forward and backward. One end of the connecting plate 33 is fixed to the transmission shaft 31, and the other end is slidably connected to the rotating plate assembly 4 via the slider 34. Specifically, the rotating plate body 41 on the rotating plate assembly 4 has a groove 411 on its side, and the slider 34 is slidably connected in the groove 411 and rotatably connected to the connecting plate 33 via the shaft. Preferably, connecting plates 33 are provided on both sides of the transmission shaft 31, and the transmission shaft 31 is preferably located at the bottom of the frame 1 and connected to the frame 1 via a connecting frame on the frame 1, thereby saving top space. In other embodiments, the drive mechanism 2 includes a drive element 21, a connecting assembly 22, and a rack 23. The drive element 21 is mounted on the frame 1 and connected to the rack 23 via the connecting assembly 22. The rack 23 is slidably connected to the frame 1 and meshes with the gear 32. The drive element 21 can drive the rack 23 to perform linear reciprocating motion via the connecting assembly 22. Driven by the drive element 21, the rack 23 performs linear reciprocating motion, which in turn drives the gear 32 to periodically rotate forward and reverse. It is worth noting that the rack 23 is always meshed with the gear 32.

[0050] In other embodiments, the driving component 21 is a motor, and the connecting assembly 22 includes a connecting rod 221 and a transmission rod 222; the connecting rod 221 is fixed to the output end of the motor, one end of the transmission rod 222 is hinged to the output end of the motor, and the other end is hinged to the rack 23. That is, the motor, connecting rod 221, transmission rod 222, and rack 23 can be approximately regarded as a crank-slider 34 mechanism, in which the motor can hold its output end when it stops rotating.

[0051] In other designs, the frame 1 is also equipped with a limiting groove 11, and a collection frame 12 is placed inside the limiting groove 11. By limiting the position of the collection frame 12 through the limiting groove 11, the picked chrysanthemums can be made to fall towards the target ground.

[0052] Preferably, the frame 1 is also equipped with a handrail. The handrail allows the operator to move the device conveniently.

[0053] The chrysanthemum picking device described above can gradually narrow the picking gap during picking and gradually widen the picking gap when preparing for the next picking.

[0054] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It should not be considered that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention.
