[0002] In recent years, with the growing demand for refined management of tea gardens, tea-picking net-covering machines have gradually become an important piece of equipment in tea production because of their ability to combine picking efficiency with sunshade regulation. After traditional net-covering machines unfold the sunshade net through a robotic arm or track system, they need to rely on manual work to fix the net to the ground or the stem of the tea tree using ground nails, straps or heavy objects.

[0003] This type of fixing method has the following significant defects: 1. Low efficiency: Manual fixation is time-consuming and labor-intensive, especially in sloping tea gardens or large-scale operations, the labor cost increases significantly.

[0004] 2. Insufficient stability: The ground nails are easily affected by the softness of the soil, the hooks may cause the net to shift due to the shaking of the tea trees, and the sunshade net is easy to fall off in strong winds, affecting the uniformity of shading.

[0005] 3. The use of fixed weight blocks greatly improves the quality of the sunshade net when it is stored. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a tea-picking net-covering device and a working method thereof, and realizes the integrated operation of net-covering fixation and net-collecting irrigation based on the tea-picking net-covering device with adaptive fixation and coordinated irrigation of a water-filled bag.

[0011] In the above scheme, preferably, the guide rail assembly includes a lower guide rail and an upper guide rail, and the lower guide rail and the upper guide rail form a gap groove for the sunshade net to pass through on one side of the sunshade net.

[0012] In the above scheme, preferably, the injection pipe is respectively connected to the injection pump and the injection pipe through a three-way valve; When covering the net, the injection pump is connected to the injection tube so that the injection tube can inject liquid into the bag body when it is moving; When the net is closed, the injection pipe is connected to the liquid injection pipe, and the liquid injection pipe moves in the reverse direction to squeeze the sac, so that the liquid in the sac is discharged through the injection pipe.

[0013] In the above scheme, preferably, the capsule body is provided with a liquid injection port, the liquid injection port is provided with a valve core, and a spring is provided between the valve core and the capsule body; The end of the liquid injection tube is provided with a plurality of liquid injection holes.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 6 .

[0024] A tea picking net covering device comprises a reel 1, a reel frame 2 and a sunshade net 3 wound on the reel 1, wherein the reel 1 is rotatably arranged on the reel frame 2, and the reel frame 2 is fixedly arranged on a traveling mechanism. This is the prior art of the net covering device and will not be described in detail here; for example, Japanese patent No. JP6030500B2 discloses a net covering device arranged on a traveling mechanism.

[0025] The sunshade net 3 is wound on the reel 1, and a counterweight block can be fixedly arranged at the head end of the sunshade net 3, so that when the sunshade net 3 starts to cover, its front end can be hung on the front end of the tea tree through the counterweight block for fixation.

[0026] A plurality of capsules 301 are symmetrically arranged on both sides of the sunshade net 3. The capsules 301 are arranged equidistantly and arranged at intervals of 1-3m along the straight direction of the sunshade net 3. The specific spacing can be adaptively adjusted according to the actual laying conditions of the tea trees. The capsules 301 are telescopic capsules, which include a fixed part 303 fixedly connected to the sunshade net 3, a telescopic part 304 and a docking plate 302. Figure 5-Figure 6As shown, the fixed part 303 is fixedly connected to the side of the sunshade net 3 by a shorter rope, and the telescopic part 304 is extended along the side away from the sunshade net 3 and fixed to the docking plate 302. The telescopic part 304 is made of deformable plastic. After the bag 301 is filled with liquid, it is stretched through the telescopic part 304 to achieve the water injection expansion of the bag 301; at the same time, the bag 301 is compressed after the telescopic part 304 is squeezed.

[0027] The reel frame 2 is symmetrically provided with guide rail assemblies 4 for guiding the capsules 301 on both sides. Figure 1-Figure 3 As shown, the guide rail assembly 4 includes a lower guide rail 401 and an upper guide rail 402. The lower guide rail 401 and the upper guide rail 402 form a gap groove 403 on one side of the sunshade net 3 for the sunshade net 3 to pass through. Specifically, the upper guide rail 402 is provided with an upper groove, and the lower guide rail 401 is provided with a lower groove. The upper groove and the lower groove are arranged opposite to each other to form a groove body for sliding and accommodating the bag body 301, so that when the sunshade net 3 is retracted and covered, the bag body 301 can slide along the groove body guide in the upper and lower grooves.

[0028] The gap groove 403 set between the upper guide rail 402 and the lower guide rail 401 is used for the rope connecting the bag body 301 and the side of the sunshade net 3 to pass through. When the telescopic part 304 is squeezed by the docking plate 302, the fixed part 303 is pressed against the wall of the upper guide rail 402 and the lower guide rail 401 on one side of the gap groove 403, thereby realizing the limitation of the lateral movement of the bag body 301; the upper guide rail 402 and the lower guide rail 401 form an open state on the side away from the sunshade net 3, which is used to make the docking plate 302 side of the bag body 301 cooperate with the components on the reel frame 2, and realize the telescopic and extension of the bag body 301 through the docking plate 302.

[0029] The reel frame 2 is movably provided with an injection tube 201 for injecting liquid into the bladder body 301. The injection tube 201 is provided with an adsorption component 202 at one end facing the bladder body 301. The adsorption component 202 is preferably a magnet, and the docking plate 302 is preferably a ferromagnetic metal plate with ferromagnetic adsorption force. When the adsorption component 202 approaches or contacts the bladder body 301, the injection tube 201 and the bladder body 301 are docked through the adsorption component 202 and the docking plate 302.

[0030] The capsule 301 is provided with a liquid injection port 305 on one side of the docking plate 302. The liquid injection port 305 is set through the center of the docking plate 302. A movable valve core 306 is provided on the liquid injection port 305. A spring 307 is provided between the valve core 306 and the capsule 301. Figure 5As shown, initially, the valve core 306 is placed in the injection port 305 to block the injection port 305. When the end of the injection tube 201 is magnetically adsorbed by the adsorption member 202 and the docking plate 302, the injection tube 201 pushes the valve core 306 in the injection port 305, and the spring 307 is stretched, so that the end of the injection tube 201 is placed in the capsule 301.

[0031] A plurality of injection holes 206 are evenly arranged on the side wall of the end of the injection tube 201. When the injection tube 201 is placed in the capsule 301, liquid can be injected into the capsule 301 through the injection holes 206. One end of the injection tube 201 is matched with the capsule 301, and the other end is connected to the injection pump and the injection pipe 102 through the three-way valve 101. The injection tube 201 is connected to the three-way valve 101 through a hose. The three-way valve 101 is a three-way electromagnetic valve. Through the cutting ring of the electromagnetic control valve body flow direction, the injection tube 201 can be connected to the injection pump or the injection pipe 102 respectively. Specifically: when covering the net, the three-way valve 101 controls the injection pump to be connected with the injection tube 201 so that the injection tube 201 injects liquid into the sac 301 when it is moving; when closing the net, the three-way valve 101 controls the injection tube 102 to be connected with the injection tube 201 so that the injection tube 201 moves in the reverse direction to squeeze the sac 301, and the sac 301 discharges the liquid in the sac 301 through the injection tube 102 under the compression and squeezing of the telescopic part 304.

[0032] The spray pipe 102 is arranged at the front end of the reel frame 2, and its spray direction is set toward the front center of the sunshade net 3, so that the sprayed liquid can be sprayed onto the surface of the sunshade net 3 that is not collected. Subsequently, when the sunshade net 3 is rolled up and collected, the surface moisture falls onto the surface of the tea leaves through vibration and squeezing to achieve irrigation.

[0033] In this embodiment, the valve core 306 structure on the capsule 301 can also be replaced by a two-way check valve to control the flow of liquid in one direction through the liquid flow direction. That is, when the capsule 301 is squeezed, the liquid in the capsule 301 flows to the injection tube 201 through the two-way check valve. When the injection tube 201 is injected, the liquid is injected into the capsule 301 through the two-way check valve.

[0034] like Figure 3-Figure 4 As shown, a vertically upward guide rod 203 is provided in the middle of the rod body of the injection tube 201, and the axis of the injection tube 201 and the plane of the docking plate 302 of the bag body 301 are always in a vertical state in space; the reel frame 2 is provided with a guide groove 204 that matches the guide rod 203, and the guide groove 204 is a long groove, and its direction is inclined from one side of the reel 1 to the direction away from the side of the reel 1 and the sunshade net 3; the guide rod 203 is provided with a guide surface that fits with the two side walls of the guide groove 204, so that the guide rod 203 is guided and slides along the guide groove 204.

[0035] The reel frame 2 is provided with a driving push rod 205 for driving the guide rod 203 to move along the guide groove 204. The driving push rod 205 can be an electric push rod. When the driving push rod 205 drives the guide rod 203 to move along the guide groove 204, the distance between the end of the injection tube 201 and the docking plate 302 of the capsule 301 is changed, thereby realizing the approach and distance between the adsorption part 202 and the docking plate 302.

[0036] like Figure 3 and Figure 4 The state shown is the state when the sunshade net 3 is collected, and the injection tube 201 is connected with the injection tube 102. At this time, the docking plate 302 is adsorbed and docked with the adsorbent 202. When the sunshade net 3 is wound and rolled, the driving push rod 205 synchronously pushes the guide rod 203 to slide to the side of the reel 1, so that the end of the injection tube 201 squeezes the capsule 301, so that the liquid in the capsule 301 is discharged through the injection tube 102. After further winding, the capsule 301 is automatically separated from the injection tube 201 by the traction force of the rope on the sunshade net 3 and is wound and collected. Then, the driving push rod 205 is retracted to the initial position, so that the injection tube 201 returns to the initial state to wait for the passage of the next capsule 301. On the contrary, when covering the net, the injection pipe 201 is connected to the injection pump, and the guide rod 203 is at one end close to the reel 1 in the guide groove 204. Then, the capsule 301 of the sunshade net 3 cooperates with the adsorption part 202 on the injection pipe 201 to be adsorbed when passing through the injection pipe 201. At the same time, the driving push rod 205 retracts to make the guide rod 203 slide in the opposite direction along the guide groove 204. The injection pipe 201 injects liquid into the capsule 301 while sliding, and when the guide rod 203 is limited by the end of the guide groove 204, the capsule 301 automatically detaches from the injection pipe 201 through the traction of the rope on the sunshade net 3, completing the injection, and then the injection pipe 201 is pushed to the initial position by the driving push rod 205, waiting for the passage of the next capsule 301.

[0037] A working method of a tea picking net covering device, the method is as follows: S1: When covering the net, the injection pipe 201 is connected to the injection pump, the sunshade net 3 is discharged outward, and the capsule 301 slides along the guide rail assembly 4. When passing through the injection pipe 201, it is adsorbed by the adsorption member 202 through the docking plate 302. When the injection pipe 201 moves, the liquid is injected into the capsule 301 through the injection pump to increase the weight of the capsule 301. After covering the net, the capsule 301 is hung on both sides of the tea tree to achieve the fixation of the tea tree after covering the net; S2: When the net is closed, the injection tube 201 is connected to the spray tube 102, and the capsule 301 containing liquid slides along the guide rail assembly 4. When passing through the injection tube 201, it is adsorbed by the adsorption component 202 through the docking plate 302. The injection tube 201 moves in the opposite direction and squeezes the capsule 301, so that the liquid in the capsule 301 is sprayed outward through the spray tube 102 to the uncollected sunshade net 3. The sunshade net 3 vibrates while collecting and vibrates the liquid on the net through the gaps to the tea trees to achieve irrigation.

[0038] In this embodiment, the above-mentioned reel, three-way valve, injection pump and driving push rod can be connected and controlled by the controller to realize the automatic control of the entire tea picking and net covering device. At the same time, various sensors can also be set on the guide rail assembly 4 of the reel frame 2 to detect the passing status of the bag 301.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
