Description

Technical Field

[0001] The invention belongs to the technical field of chrysanthemum picking, and in particular relates to a chrysanthemum picking device. Background Art

[0002] Chrysanthemum is a plant that can clear away heat, relieve summer heat, improve eyesight and nourish the mind. It has a certain effect on dry mouth, excessive internal heat and dry eyes. It is one of the important formulas of mainstream herbal tea on the market. At present, there are professional chrysanthemum planting bases in Jiangsu, Liaoning, Chongqing and other regions in my country. However, the flowering period of chrysanthemum is short. If it is not picked in time, the chrysanthemum will wither and lose its economic value.

[0003] At present, chrysanthemums are mainly picked manually, which is time-consuming and requires a lot of manpower, and the picking efficiency is low. There are few chrysanthemum picking and harvesting machines on the market. They are generally picked by combing brushes. In the current common harvesting devices, the gap between the comb teeth, that is, the picking gap, is often fixed, which makes it easy to miss picking or press the chrysanthemums under the comb teeth during the picking process. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a chrysanthemum harvesting device to solve the technical problem mentioned in the above background technology that the gap between the comb teeth, i.e. the picking gap, is often fixed in the currently common harvesting devices.

[0005] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention includes:

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

By setting the telescopic connection member to have an elastic telescopic amount, the abutment rod can move more smoothly in 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 movable picking comb teeth maintain the initial position, the slope groove is connected to the flat groove, the lowest end of the slope groove and the flat groove are in the same plane, and the flat groove is also rotatably provided with a baffle assembly, which is elastic; when the rotating plate assembly rotates forward, the pushing component is guided into the slope groove by the baffle assembly, and the rotating plate assembly falls from the slope groove into the flat groove before reversing, and slides along the flat groove during reversing, and pushes the baffle assembly to return to the initial position. That is, the picking gap gradually shrinks to the minimum when the picking is rotated and lifted, and resets to the maximum value when the reversal is put down, further avoiding the problem of knocking down the chrysanthemums due to the small gap when putting them down.

[0012] Furthermore, the baffle assembly includes a baffle body, a baffle shaft and an elastic connecting member; the baffle body is rotatably connected to the flat groove through the baffle shaft, and abuts against the side of the slope groove away from the rotating plate assembly through the elastic connecting member, and the elastic connecting member is arranged in the upper horizontal groove.

[0013] Furthermore, the rotating plate assembly includes a rotating plate body and side leakage prevention plates; the baffle assembly is rotatably arranged on the frame, and the rotation of the transmission assembly can drive the rotation of the rotating plate body; the side leakage prevention plates are fixedly arranged on both sides of the rotating plate body. By providing the side leakage prevention plates, the chrysanthemums can be prevented from accidentally sliding off from the side when picking.

[0017] Furthermore, the frame is provided with a limit slot, in which a collecting frame is placed. The position of the collecting frame is limited by the limit slot, so that the picked chrysanthemums can fall toward the target.

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

[0019] During picking, the picking gap gradually decreases from large to small, thereby reducing the possibility of some chrysanthemums slipping out of the picking gap due to the gap being too large during picking, thereby reducing the possibility of missing picking;

[0020] After picking is completed, the picking gap gradually expands from a small size, thereby reducing the possibility that the chrysanthemums cannot be stuck in the picking gap when the picking comb falls or the chrysanthemums are directly pulled off the plant due to the picking gap being too small.

[0034] The embodiment of the present invention is intended to introduce and illustrate the structural composition of the chrysanthemum harvesting device and the coordination relationship between the various components. Unless otherwise specified, the size, material and manufacturing process of each component in the chrysanthemum harvesting device in the embodiment of the present invention can be selected according to the specific situation and are not specifically limited or explained here.

[0035] Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. For those skilled in the art, the present invention can be fully understood without the description of these details.

[0036] Please also read Figure 1-Figure 5 The present embodiment provides 1. a chrysanthemum harvesting device, characterized in that it comprises a frame 1, a driving mechanism 2, a transmission mechanism 3, a rotating plate assembly 4, fixed picking comb teeth 5, a movable picking comb teeth 6, a pushing assembly 7 and a side baffle 8;

[0037] The driving mechanism 2 is arranged on the frame 1, and the transmission mechanism 3 and the rotating plate assembly 4 are rotatably arranged on the frame 1 respectively. The driving mechanism 2 can periodically drive the transmission mechanism 3 to rotate forward and reverse, and then drive 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 reverse rotation of the rotating plate assembly 4. After the driving mechanism 2 drives the transmission mechanism 3 to rotate forward to a certain angle, it drives the transmission mechanism 3 to 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 a fuselage and a mechanism such as a moving wheel that drives it to move. There are a lot of specific descriptions in the prior art, so this application will not repeat them here.

[0038] A plurality of fixed picking comb teeth 5 are provided and fixed on the rotating plate assembly 4, a plurality of movable picking comb teeth 6 are provided and slidably provided on the rotating plate assembly 4, and a pushing assembly 7 is slidably provided on the rotating plate assembly 4 and is sequentially connected with each movable picking comb tooth 6; that is, each movable picking comb tooth 6 slides with the sliding of the pushing assembly 7. The side baffle 8 is fixed on the frame 1 and is provided with a guide groove 81 with a slope. The pushing assembly 7 abuts against the guide groove 81 and moves from a low position to a high position with the forward rotation of the rotating plate assembly 4, driving each movable picking comb tooth 6 to move toward the fixed picking comb teeth 5 or the rotating plate assembly 4.

[0039] That is to say, during the forward rotation of the turn plate assembly 4, the pushing assembly 7 slides in the direction close to the turn plate assembly 4 by means of the squeezing of the slope of the guide groove 81, thereby driving each other movable picking comb teeth 6 to slide, thereby gradually reducing the gap between the movable picking comb teeth 6 and the fixed picking comb teeth 5 or the turn plate assembly 4 in its moving direction. Since the pushing assembly 7 is elastic, the pushing assembly 7 can drive each movable picking comb tooth 6 to reset after the turn plate assembly 4 is reversed. Specifically, in the initial state, the movable picking comb teeth 6 are close to the turn plate assembly 4 or the fixed picking comb teeth 5. During the forward rotation, the sliding distance to the adjacent fixed picking comb teeth 5 or the turn plate assembly 4 is the picking gap for picking chrysanthemums. By reducing the picking gap, the chrysanthemums are picked during the rotation. In addition, as for the connection strength problem of the side baffle 8, it can be improved by adding reinforcing ribs and other methods, which will not be elaborated in this article.

[0040] The push assembly 7 includes a sliding rod 71, a telescopic connection member 72, a support spring 73 and an abutment rod 74; the sliding rod 71 is slidably arranged on the rotating plate assembly 4, the mobile picking comb 6 is fixed on the sliding rod 71, the telescopic connection member 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, and the abutment rod 74 is fixed on the telescopic rod. The abutment rod 74 abuts in the guide groove 81 through the support spring 73, and its abutment end is preferably provided with a rounded corner or a spherical surface.

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

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

[0043] During picking, the picking gap gradually decreases from large to small, thereby reducing the possibility of some chrysanthemums slipping out of the picking gap due to the gap being too large during picking, thereby reducing the possibility of missing picking;

[0044] After picking is completed, the picking gap gradually expands from a small size, thereby reducing the possibility that the chrysanthemums cannot be stuck in the picking gap when the picking comb falls or the chrysanthemums are directly pulled off the plant due to the picking gap being too small.

[0045] In other schemes, 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, it moves the picking comb teeth 6 to maintain the 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 in the same plane, and a baffle assembly 9 is also rotatably provided on the flat groove 812, and the baffle assembly 9 is elastic; when the turntable assembly 4 rotates forward, the pushing component 7 is guided into the slope groove 811 by the baffle assembly 9, and the turntable assembly 4 falls from the slope groove 811 into the flat groove 812 before reversing, and slides along the flat groove 812 during reversing, pushing the baffle assembly 9 and returning to the initial position.

[0046] Specifically, the flat groove 812 is composed of an arc groove and an inclined L-shaped groove, the long side of the L-shaped groove is connected to the end of the arc 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 groove. One end of the rotating shaft of the baffle assembly 9 is arranged on the arc groove, and the other end is abutted on the slope groove 811 away from the side of the turn plate assembly 4 through elastic force, so that the pushing assembly 7 moves to the baffle assembly 9 on the arc groove when the turn plate assembly 4 rotates forward. Since the baffle assembly 9 is pulled by its own elastic force and abuts on 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 turn plate assembly 4 reverses, and then moves along the L-shaped groove to the arc groove, pushing the baffle assembly 9 to rotate in the direction close to the turn plate assembly 4 until it is reset. The arc groove is preferably concentric with the axis of the rotating plate assembly 4, so that its early rotation is smoother. It should be understood that the pushing assembly 7 is abutted against the inner bottom surface of the guide groove 81 by its own elastic force, and the planes formed by any three abutment points of the pushing assembly 7 in the inner bottom surface of the flat groove 812 are coplanar. Through this structure, the mobile picking comb teeth 6 can return to the initial distance after rotating and approaching the fixed picking comb teeth 5 or the rotating plate assembly 4, that is, the picking gap gradually shrinks to the minimum when the picking is rotated and lifted, and resets to the maximum value when it is reversed and put down, further avoiding the problem of knocking down the chrysanthemums due to the small gap when putting them down.

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

[0048] In other schemes, the rotating plate assembly 4 includes a rotating plate body 41 and a side leakage prevention plate 42; the baffle assembly 9 is rotatably arranged on the frame 1, and the rotation of the transmission assembly can drive the rotation of the rotating plate body 41; the side leakage prevention plates 42 are fixedly arranged on both sides of the rotating plate body 41. Preferably, the sliding rod 71 is slidably arranged on the side leakage prevention plate 42, and the support spring 73 is located between the telescopic connecting member 72 and the side leakage prevention plate 42 in a compressed state. By providing the side leakage prevention plate 42, it can prevent the chrysanthemum from accidentally sliding from the side when picking.

[0049] In other schemes, 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, the gear 32 is coaxially fixed on the transmission shaft 31, and the driving mechanism 2 can drive the gear 32 to rotate forward and reverse; one end of the connecting plate 33 is fixed on the transmission shaft 31, and the other end is slidably connected to the rotating plate assembly 4 through the slider 34. Specifically, a sliding groove 411 is provided on the side of the rotating plate body 41 of the rotating plate assembly 4, and the slider 34 is slidably connected in the sliding groove 411 and is rotatably connected to the connecting plate 33 through the shaft. Preferably, connecting plates 33 are provided on both sides of the transmission shaft 31, and the transmission shaft 31 is preferably arranged at the bottom of the frame 1, and is connected to the frame 1 through a connecting frame on the frame 1, thereby saving top space.

[0050] In other schemes, the driving mechanism 2 includes a driving member 21, a connecting assembly 22 and a rack 23; the driving member 21 is arranged on the frame 1 and connected to the rack 23 through the connecting assembly 22; the rack 23 is slidably connected to the frame 1 and meshes with the gear 32; the driving member 21 can drive the rack 23 to perform linear reciprocating motion through the connecting assembly 22. Driven by the driving member 21, the rack 23 performs linear reciprocating motion, thereby driving the gear 32 to periodically rotate forward and reverse. It is worth noting that the rack 23 is always meshed with the gear 32.

[0051] In other embodiments, the driving member 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, and 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, the connecting rod 221, the transmission rod 222 and the rack 23 can be approximately regarded as a crank slider 34 mechanism, and the motor can hold its output end tightly when it stops rotating.

[0052] In other solutions, the frame 1 is further provided with a limiting groove 11, and a collecting frame 12 is further placed in the limiting groove 11. The limiting groove 11 limits the position of the collecting frame 12, so that the picked chrysanthemums can fall toward the target.

[0053] Preferably, an armrest is also provided on the frame 1. The armrest enables the operator to move the device conveniently.

[0054] The chrysanthemum picking device can gradually reduce the picking gap during picking, and gradually expand the picking gap when preparing for the next picking.
