DETAILED DESCRIPTION

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by users of the present invention without creative work belong to the protection scope of the present invention.

[0043] refer to Figures 1 to 4 , a tea picking machine for picking and grading famous and high-quality tea, comprising a frame 1;

[0044] The frame 1 is provided with a walking mechanism, which is a crawler-type walking mechanism 2; the walking mechanism is used to drive the frame 1 to walk in the tea field;

[0045] The frame 1 is also provided with at least one set of tea picking components 3;

[0046] The tea picking assembly 3 includes an impeller, a guide platform 31 and a cutting platform. The guide platform 31 is provided with a guide channel 32 for tea leaves to pass through. The guide platform 31 is provided with a visual detector 33 for identifying tea leaves in the guide channel 32. It also includes a cutting blade 34. The cutting blade 34 is located directly behind the transmission direction of the guide platform 31. Once the leaf picking point is identified, the blade will move to a certain height for cutting. The guide platform 31 is also provided with a negative pressure collector 35 for collecting the tea leaves cut by the cutting blade 34.

[0047] The negative pressure collector 35 comprises a collecting port 351, and there are at least two collecting ports 351, and tea leaves of different qualities pass through each collecting port 351;

[0048] The guide vane platform 31 is also provided with a controller, and the visual detector 33 is in communication connection with the controller. The controller controls the cutting blade 34 and the negative pressure collector 35 to work according to the parameters detected by the visual detector 33 .

[0049] The frame 1 is also provided with a traction assembly, which is used to drive the walking mechanism to move and realize the walking of the tea picking machine.

[0050] The visual detector 33 and the controller are both common structures in the prior art.

[0051] The visual detector 33 is used to detect the shape of the tea leaves, that is, the grade of the tea leaves, such as single-leaf tea or multi-leaf tea, etc. After the visual detector 33 detects the grade of the tea leaves, it sends a signal to the controller, and the controller controls the cutting blade 34 to work, and the cutting blade 34 cuts the tea leaves. At the same time, the controller controls the negative pressure collector 35 to work, so that the cut tea leaves enter the corresponding collecting port 351.

[0052] As for inferior tea leaves that do not need to be collected, they can be directly discharged into the tea fields.

[0053] Specifically, the impeller 36 is arranged on the guide vane platform 31, and the impeller 36 is rotatably connected to the guide vane platform 31. The ratio of the impeller impeller speed, the guide vane speed and the frame travel speed is 2:1.5:1.

[0054] There are two impellers 36, both of which are rotatably connected to the guide vane platform 31, each of which is driven by an independent first driver, and the two impellers 36 are respectively located on both sides of the guide vane channel 32. There are two impellers in a group, both of which are rotatably connected to the guide vane platform, forming an angle of 30° with the forward direction, each of which is driven by an independent first driver, and the two impellers are respectively located on both sides of the guide vane channel.

[0055] The paddle wheel 36 includes a rotating shaft driven by the first driver. The rotating shaft is provided with elastic paddle teeth 361 . The elastic paddle teeth 361 are evenly distributed on the rotating shaft along the circumferential direction of the rotating shaft.

[0056] The elastic leaf-pushing teeth 361 can be made of a metal material with elastic deformation function, and a rubber layer can be sleeved on the elastic leaf-pushing teeth 361 to prevent the tea leaves from being damaged by the elastic leaf-pushing teeth 361 .

[0057] The first driver may be a motor. The guide vane platform 31 includes a bracket 37 , which is fixed on the frame 1 , and the visual detector 33 , the cutting blade 34 and the negative pressure collector 35 are all fixed on the bracket 37 .

[0058] The first driver can be fixed to the bracket 37 by screws.

[0059] The visual detector 33 may be disposed on any side of the guide vane channel 32 , for example, may be fixed to any side of the guide vane channel 32 by screws.

[0060] refer to Figures 1 to 4 Specifically, the guide vane platform 31 further includes a conveyor belt 38 disposed on the bracket 37 , and there are two conveyor belts 38 , and the guide vane channel 32 is formed between the two conveyor belts 38 .

[0061] The conveyor belt 38 includes a driving pulley rotatably connected to the bracket 37, a driven pulley rotatably connected to the bracket 37, and a belt body sleeved on the driving pulley and the driven pulley, and the driving pulley is driven by the rotating shaft.

[0062] The bracket 37 is also provided with an electromagnet 341 for driving the cutting blade 34 to move up and down. The electromagnet 341 includes a coil fixed on the bracket 37 and a movable block driven by the coil. The cutting blade 34 is fixed on the movable block.

[0063] refer to Figures 1 to 4 A further improved solution is as follows: the cutting blade 34 includes a cutting edge portion, the cutting edge portion is provided with a groove 342, the groove 342 is evenly arranged along the length direction of the cutting edge portion, and the cross-sectional shape of the groove 342 is semicircular.

[0064] The groove 342 may also be in other shapes. The groove 342 is used to cooperate with the blade to tear the tea leaves. For example, when the tea leaves are not completely cut off, since the tea picking machine is moving relative to the tea leaves, part of the tea leaves enter the groove 342 and are pulled by the groove 342, so that the tea leaves can be torn off and the tea leaves can be harvested.

[0065] Specifically: the negative pressure collector 35 also includes a negative pressure generator, which is connected to the collecting port 351 through a pipeline. The collecting port 351 corresponds to the pipeline one by one. Each pipeline is provided with a control valve for controlling the on and off of the pipeline, and the control valve is controlled by the controller.

[0066] The working principle of this embodiment:

[0067] When the tea picking machine is moving in the tea field, the impeller 36 is in a rotating state, and the impeller 36 guides the tea leaves to the guide vane channel 32. At this time, the conveyor belt 38 forming the guide vane channel 32 is also in a rotating state, and the conveyor belt 38 conveys the tea leaves into the guide vane channel 32.

[0068] The tea leaves entering the guide vane channel 32 are detected by the visual detector 33, and the visual detector 33 detects the grade of the tea leaves. Then, the conveyor belt 38 continuously conveys the tea leaves in the guide vane channel 32. Since the speed of the conveyor belt 38 is different from that of the tea picking machine, the conveyor belt 38 will bend the tea leaves during the conveying process, so that the handle of the tea leaves is in a water state.

[0069] The controller then controls the electromagnet 341 to work, and the electromagnet 341 drives the cutting blade 34 to move to cut the tea leaves.

[0070] After the tea leaves are cut, the controller controls the negative pressure collector 35 to work, so that the corresponding collecting port 351 generates negative pressure to suck the cut tea leaves into the corresponding collecting port 351, thereby completing the harvesting and sorting of the tea leaves.

[0071] The present invention is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in their shapes or structures, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
