[0018] The present application is not limited by the following embodiments, and the specific implementation method can be determined according to the technical solution of the present application and actual conditions.

[0019] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached Figure 1 The layout is described in detail, such as the positional relationship of top, bottom, left, right, etc. is based on the instructions attached to the manual. Figure 1 It is determined by the layout direction.

[0020] The present invention will be further described below in conjunction with embodiments and drawings. Figures 1 to 5 As shown, the chamomile flower head harvester includes a tractor 1, a flower head harvester, and a negative pressure flower collector. The front and rear sides of the tractor 1 are respectively provided with a front suspension mechanism and a rear suspension mechanism. The flower head harvester is installed on the front suspension mechanism, and the negative pressure flower collector is installed on the rear suspension mechanism. The tractor 1 is also provided with a hydraulic control system and a power output shaft 2 installed on the rear side of the tractor 1. The hydraulic control system is connected to the flower head harvester to control the operation of the flower head harvester. The power output shaft 2 of the tractor 1 is connected to the negative pressure flower collector to control the operation of the negative pressure flower collector. A flower head conveying hose 3 is provided on the body of the tractor 1. One end of the flower head conveying hose 3 is connected to the discharge port of the flower head harvester, and the other end of the flower head conveying hose 3 is connected to the feed port of the negative pressure flower collector.

[0021] When the tractor 1 is started, the power output shaft 2 and the hydraulic control system on the tractor 1 start working. At this time, the hydraulic oil in the hydraulic control system enters the hydraulic motor 4 on the flower head harvester to drive the hydraulic motor 4 to run. The hydraulic motor 4 serves as a power source to drive the operation of the entire flower head harvester. At the same time, the power output shaft 2 at the rear of the tractor 1 drives the negative pressure flower collector through the universal shaft 5, so that the negative pressure flower collector generates negative pressure. When the tractor 1 is moving in a field planted with chamomile, the flower head harvester will harvest the chamomile in the field. The flower stem part of the chamomile will be automatically thrown away in the process and finally form the required flower heads. The negative pressure generated by the negative pressure flower collector sucks the flower heads formed by the flower head harvester into the flower collecting box 6 on the negative pressure flower collector for storage through the flower head conveying hose 3. When the flower collecting box 6 is full of flowers, it is transported to the tractor 1 The power output shaft 2 and the hydraulic control system are used to stop the flower head harvester and the negative pressure flower collector, and then the flower collecting box 6 on the negative pressure flower collector is manually opened to unload the collected flower heads uniformly, and then the above operation process is repeated to continue the collection operation of chamomile flower heads. Compared with the existing manual harvesting operation and the auxiliary harvesting device in the shape of spike teeth 20 for auxiliary flower harvesting, the present invention can perform fully automatic and continuous harvesting of chamomile flower heads, which saves time and effort and has high efficiency, greatly reducing the harvesting cost, and the present invention has a simple structure, the flower head harvester and the negative pressure flower collector are installed on the existing tractor 1, and have strong maneuverability and flexibility, so it is particularly suitable for field operations of chamomile, which is conducive to promotion and promotes farmers to expand the planting area of ​​chamomile, and has strong practicality. The front suspension mechanism and the rear suspension mechanism of the tractor 1 are both existing well-known technologies.

[0022] According to actual needs, the above-mentioned chamomile flower head harvester is further optimized and / or improved: further, as shown in the attached Figures 1 to 3As shown, the flower head harvester includes a front base 7, a left turntable 8, a right turntable 9, and a hydraulic motor 4. The front base 7 is installed on the front suspension mechanism. The front and rear sides of the front base 7 are respectively fixedly connected with a front support 10 and a rear support 11. The left and right sides of the front support 10 are respectively installed with a left shaft 12 and a right shaft 13. The right side of the extended end of the left shaft 12 is fixedly connected to the left turntable 8, and the left side of the extended end of the right shaft 13 is fixedly connected to the right turntable 9. A flower receiving bucket 14 with a low middle and high surroundings is arranged between the left turntable 8 and the right turntable 9. The upper opening of the flower receiving bucket 14 is a feeding port, and a flower leakage port 15 is arranged at the bottom of the flower receiving bucket 14. A negative pressure box 16 is arranged below the flower bucket 14, and the negative pressure box 16 is connected to the flower leakage port 15, and the discharge port of the negative pressure box 16 is communicated with the flower head conveying hose 3. The connecting arm 33 arranged on the front base 7 is fixedly connected to the bottom outer side of the flower receiving bucket 14, and a plurality of cantilever beams 17 are evenly distributed along the circumferential direction of the right end face of the left turntable 8, and a row of spike teeth 20 are transversely fixed along the length direction of the cantilever beam 17, and gaps are arranged between adjacent spike teeth 20. When the spike teeth 20 follow the rotating left turntable 8 to run to the highest point, the spike teeth 20 are in a horizontal state and the spike teeth 20 face backwards. Similarly, the cantilever beam 17 and the spike teeth 20 are arranged on the right turntable 9, and the left turntable 8 and the right turntable 9 are connected. The cantilever beams 17 on the turntable 9 correspond to each other on the left and right sides, and the spike teeth 20 surround the outer side of the flower receiving bucket 14. A space is set between the cantilever beams 17 on the left turntable 8 and the right turntable 9, and the connecting arm 33 is located at the space. A tool holder 18 is also fixed on the front base 7, and an outrigger arm 19 is provided on the tool holder 18. The outrigger arm 19 is located above the connecting arm 33 and extends through the space between the left turntable 8 and the right turntable 9. A tool is fixedly connected to the left and right sides of the outrigger arm 19, respectively. A thin blade 21 is fixedly provided on the tool horizontally, and the spike teeth 20 surround the outer side of the thin blade 21. The upper blade surface of the thin blade 21 can be aligned with the lower end surface of the spike teeth 20 that runs to the highest point. The blade 21 of the thin blade 21 faces forward, the lateral width of the feed port of the flower receiving bucket 14 corresponds to the lateral width between the left turntable 8 and the right turntable 9 to receive the flower heads cut off from the thin blade 21, and a synchronous rotating shaft 22 is horizontally installed on the rear support 11, and a sprocket drive is arranged between the left outer end of the synchronous rotating shaft 22 and the left outer end of the left rotating shaft 12, and a sprocket drive is also arranged between the right outer end of the synchronous rotating shaft 22 and the right outer end of the right rotating shaft 13. A hydraulic motor 4 is also installed on the base, and a pulley drive is arranged between the rotating shaft end of the hydraulic motor 4 and the synchronous rotating shaft 22. The hydraulic control system on the tractor 1 is connected to the hydraulic motor 4 to control its operation.

[0023] The specific harvesting process of the chamomile flower heads by the flower head harvester is as follows: when the hydraulic oil in the hydraulic control system of the tractor 1 enters the hydraulic motor 4, it will drive the operation of the hydraulic motor 4, and the running hydraulic motor 4 drives the synchronous shaft 22 to rotate through the pulley transmission, and the synchronous shaft 22 drives the left turntable 8 and the right turntable 9 to rotate synchronously through the sprocket transmission. The running left turntable 8 and the right turntable 9 will drive their own spike teeth 20 to make a circular motion. After the chamomile on the ground passes through the gap between the spike teeth 20 and enters the spike teeth 20 located at the lower part of the left turntable 8 and the right turntable 9, as the spike teeth 20 move from low to high, it will have a certain impact on the chamomile flower heads. The flower heads of chamomile will form two states under this action. One is that the flower heads are stuck in the gap between adjacent spike teeth 20 and are usually accompanied by a flower stem. The other is that a few flower heads are in a free state. Most of these flower heads in a free state will fall into the flower receiving bucket 14 when the spike teeth 20 move from low to high, so as to reduce the loss and waste in the process of flower head harvesting. The remaining flower heads stuck on the spike teeth 20 will follow the spike teeth 20 to run to the highest point. When the spike teeth 20 run to the highest point, the flower heads face downward and will be cut off by the thin blade 21 on the tool, and the flower heads will naturally fall into the flower receiving bucket 14. The reason for putting the thin blade 21 on the tool is that the flower heads are cut off by the thin blade 21 on the tool. The upper blade surface of the blade 21 is designed to be tangent to the lower end surface of the spike tooth 20 that runs to the highest point. This is because this position is exactly where the chamomile flower head is stuck on the spike tooth 20. Cutting from here can not only accurately cut off the flower head, but the upper blade surface of the thin blade 21 can also have an outward squeezing effect on the flower stem from the connection end between the flower head and the flower stem, so that after the thin blade 21 cuts off the flower head, the flower stem is more likely to be thrown off the spike tooth 20 by inertia. Since the spike tooth 20 surrounds the outside of the flower receiving bucket 14, the flower stem rarely enters the flower receiving bucket 14. Even if there is still a small amount of flower stem left on the spike tooth 20 at this time, it will be During the chrysanthemum harvesting process, the newly collected chamomiles are squeezed out, so the continuous harvesting operation of the chamomile flower heads will not be affected. In this way, the flower head harvester can continuously and efficiently harvest the chamomile flower heads in the field. The flower heads entering the flower receiving bucket 14 enter the negative pressure box 16 through the flower leakage port 15. The flower heads are then sucked into the flower collecting box 6 on the negative pressure flower collector through the flower head conveying hose 3 for storage. The hydraulic motor 4 is an existing well-known technology. The pulley transmission or sprocket transmission described in the technical solution is only a form of transmission between shafts, and other forms can also be used as long as the mutual transmission between the shafts can be achieved.

[0024] Further, as attached Figure 5As shown, the negative pressure flower collector includes a flower collecting box 6, a speed increasing gear box 23, a universal shaft 5, a centrifugal fan 24, and a rear base 25. The rear base 25 is installed on the rear suspension system of the tractor 1. The flower collecting box 6, the speed increasing gear box 23, and the centrifugal fan 24 are all fixedly installed on the rear base 25. One end of the universal shaft 5 is installed on the power output shaft 2 on the rear side of the tractor 1, and the other end of the universal shaft 5 is installed on the input shaft of the speed increasing gear box 23. The output shaft of the speed increasing gear box 23 and the fan shaft on the centrifugal fan 24 are driven by a pulley. The axial air inlet of the centrifugal fan 24 is connected to the flower collecting box 6 by setting a connecting hose 26. One end of the flower head conveying hose 3 is connected to the feeding port of the flower collecting box 6, and the other end of the flower head conveying hose 3 is connected to the discharging port of the flower head harvester. A filter cover 27 is installed in the flower collecting box 6. The filter cover 27 is arranged at the connecting port of the flower collecting box 6 and the connecting hose 26. The flower collecting box 6 is also equipped with a sealing door for unloading.

[0025] The specific working process of the negative pressure flower collector is as follows: the tractor 1 drives the universal shaft 5 to rotate through the power output shaft 2 at the rear, and under the action of the speed-increasing gear box 23, the low speed input by the universal shaft 5 can be converted into the high speed output by the speed-increasing gear box 23, so as to ensure the normal operation of the centrifugal fan 24. The running centrifugal fan 24 will form a negative pressure in the flower collecting box 6 and the flower head conveying hose 3, so as to suck the flower heads in the negative pressure box 16 into the flower collecting box 6. The filter cover 27 can prevent the flower heads entering the flower collecting box 6 from being sucked into the centrifugal fan 24 due to the negative pressure, thereby ensuring the safe operation of the centrifugal fan 24. When the flower collecting box 6 is full of flower heads, the negative pressure flower collector and the flower head harvester are stopped by controlling the tractor 1, and then the sealing door is manually opened for unloading. The centrifugal fan 24, the universal shaft 5, and the speed-increasing gear box 23 are all existing well-known technologies, and the flower head conveying hose 3 can be other hoses such as a PVC transparent steel wire hose.

[0026] Further, as attached Figure 1 , 2 As shown in Figures 3 and 5, a divider is also fixedly provided on the front side of the front base 7, and the divider includes a left paddle 28 and a right paddle 29. One end of the left paddle 28 is fixedly connected to one end of the right paddle 29 to form a pointed protrusion 30, and the pointed protrusion 30 corresponds to the empty space between the cantilever beams 17. The other end of the left paddle 28 is fixedly connected to the left side of the front base 7, and the other end of the right paddle 29 is fixedly connected to the right side of the front base 7. The left paddle 28 and the right paddle 29 together constitute a "human" shaped frame structure.

[0027] In order to leave the required installation position for the outrigger arm 19 and the connecting arm 33, an empty space is set between the cantilever beam 17 on the left turntable 8 and the cantilever beam 17 on the right turntable 9. However, it is precisely because of the existence of this empty space that the flower head harvester cannot normally harvest the chamomile flower heads located at this position. In order to avoid this situation, a divider structure is set. Through the "human" shaped frame structure of the divider, the chamomile located at the empty space can be divided to the left and right sides of the empty space so that the spike teeth 20 can harvest it. The flowers on chamomile are high and low, and some of the lower flowers cannot be harvested by the flower head harvester. However, this is not a defect of the present invention. Why do I say this? This is because even the traditional manual picking method will not harvest all the flower heads on the chamomile cleanly. It is necessary to deliberately leave some flower heads in order to allow these flower heads to grow naturally, mature, and form seeds. After the seeds mature, they fall into the ground. When watered next year, new chamomile will grow, which can greatly reduce the sowing amount next year and form a virtuous circle. Further improvements can be made later according to actual needs. A hydraulic cylinder or a hydraulic arm connected to the hydraulic control system of the tractor 1 can be installed on the front suspension mechanism of the tractor 1 to adjust the harvesting height of the flower head harvester.

[0028] Further, as attached Figure 1 , 2 As shown in Figures 3 and 5, the flower receiving bucket 14 includes a bottom arc plate, a left baffle and a right baffle, which together form a groove structure with a feed port on the upper side, a flower leaking mouth 15 is provided at the lowest point of the bottom arc plate, and the flower leaking mouth 15 is connected to the negative pressure box 16 pipe, the bottom arc plate area on the front side of the flower leaking mouth 15 is the front arc plate 31, and the bottom arc plate area on the rear side of the flower leaking mouth 15 is the rear arc plate 32, the top edge of the rear arc plate 32 is higher than the top edge of the front arc plate 31, the material receiving area of ​​the rear arc plate 32 does not exceed three-eighths of the circumferential surface of the cantilever beam 17, and the material receiving area of ​​the front arc plate 31 does not exceed one-eighth of the circumferential surface of the cantilever beam 17.

[0029] The outward extension of the front arc plate 31 should be appropriately shorter, because the side of the front arc plate 31 is the harvesting side of the flower heads. If it is too long, it will affect the harvesting of the flower heads. If it is too short, most of the flower heads scattered on the spike teeth 20 will fall to the ground during the rising process of the spike teeth 20, causing waste. The optimal size of the front arc plate 31 is to ensure that as many flower heads scattered on the spike teeth 20 as possible enter the flower receiving bucket 14 without affecting the harvesting of the flower heads. The function of the cantilever beam 17 is not only to provide a fixed place for the spike teeth 20, but also to play a certain blocking role for the flower heads scattered on the spike teeth 20 within a certain height range, so as to prevent the flower heads from falling to the ground too early. The outward extension of the rear arc plate 32 is preferably as long as possible without affecting the flower heads from falling into the flower receiving bucket 14, so as to further prevent the flower stems from entering the flower receiving bucket 14.

[0030] Further, as attached Figure 5 As shown, the outer wall of the flower collecting box 6 is in a cone shape with a larger upper part and a smaller lower part. The flower head conveying hose 3 is connected to the material port at the top of the flower collecting box 6. One end of the connecting hose 26 is connected to the upper outer wall of the flower collecting box 6. The other end of the connecting hose 26 is connected to the axial air inlet of the centrifugal fan 24. The sealing door is installed at the lower part of the outer wall of the flower collecting box 6.

[0031] The shape of the flower collecting box 6, which is larger at the top and smaller at the bottom, is conducive to the collection of the flower heads at the bottom of the flower collecting box 6, and then it is convenient to unload the flower heads from the sealed door. There are many structural forms of the sealed door. For example, the sealed door includes a door body and a door lock. The door lock is installed in the door body. A door frame connected to the interior of the flower collecting box 6 is arranged on the side wall at the lower part of the flower collecting box 6. The door body is installed in the door frame. A handle for controlling the door lock switch is installed on the outside of the door body. A sealing strip is arranged on the door frame to seal the gap formed between the door body and the door frame when the door body is closed, thereby ensuring that the negative pressure flower collector is in a negative pressure state when working.

[0032] The above description is only an example for clearly explaining the present application, and is not intended to limit the implementation methods of the present application. Any obvious changes or modifications derived from the technical solution of the present application are still within the scope of protection of the present application.
