Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, and in particular to a tea-picking netting device and its working method. Background Technology

[0002] In recent years, with the increasing demand for refined management of tea gardens, tea-picking netting machines have gradually become important equipment in tea production due to their combination of picking efficiency and shading control capabilities. Traditional netting machines deploy the shading net through a robotic arm or track system, and then rely on manual labor to fix the net to the ground or tea tree stems using ground nails, straps, or weights.

[0003] This type of fixing method has the following significant drawbacks:

[0004] 1. Low efficiency: Manual labor is time-consuming and labor-intensive, especially in tea gardens on slopes or in large-scale operations, where labor costs increase significantly.

[0005] 2. Insufficient stability: The ground nails are easily affected by the looseness of the soil, and the hooks may cause the net to shift due to the swaying of the tea trees. The shade net is prone to falling off in strong winds, affecting the uniformity of shading.

[0006] 3. Using fixed load-bearing blocks greatly improves the quality of the shade net when it is stored. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a tea-picking netting device and its working method. Based on a water-filled bladder that adaptively fixes and coordinates with irrigation, the tea-picking netting device achieves integrated operation of netting fixation and netting irrigation.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a tea-picking netting device, comprising a roller, a roller frame, and a shade net wound on the roller;

[0009] The shade net has several symmetrical and equidistant pockets on both sides;

[0010] The roll frame is equipped with a guide rail assembly that cooperates with the bladder body;

[0011] The roll frame is movably equipped with an injection tube for injecting liquid into the capsule;

[0012] The injection tube is equipped with an adsorption element, and the side of the bladder away from the shade net is equipped with a docking plate that cooperates with the adsorption element, so that the injection tube can accurately inject liquid into the bladder after the docking plate cooperates with the adsorption element.

[0013] In the above scheme, preferably, the adsorption element is a magnet and the docking plate is a ferromagnetic metal plate.

[0014] In the above scheme, preferably, the injection tube is provided with a guide rod, and the reel frame is provided with a guide groove that cooperates with the guide rod.

[0015] In the above scheme, preferably, the drum frame is provided with a drive push rod that drives the guide rod to move along the guide groove.

[0016] 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 on one side of the shading net for the shading net to pass through.

[0017] In the above scheme, preferably, the injection pipe is connected to an injection pump and a spray pipe respectively through a three-way valve;

[0018] When the net is covered, the injection pump is connected to the injection pipe so that the injection pipe injects liquid into the capsule when it is in motion;

[0019] When closing the net, the injection pipe is connected to the liquid injection pipe, and the liquid injection pipe moves in the opposite direction to squeeze the bladder, so as to discharge the liquid in the bladder through the injection pipe.

[0020] In the above scheme, preferably, the bladder body is provided with an injection port, the injection port is provided with a valve core, and a spring is provided between the valve core and the bladder body;

[0021] The end of the injection tube is provided with several injection holes.

[0022] In the above scheme, preferably, the bladder is provided with an injection port, and the injection port is provided with a two-way check valve;

[0023] The telescopic part is made of deformable plastic, and can be compressed and expanded by squeezing through the injection tube and injecting liquid.

[0024] In the above scheme, a preferred method for operating a tea-picking netting device is as follows:

[0025] S1: When covering the net, the injection pipe is connected to the injection pump, the shade net is discharged outward, the bag slides along the guide rail assembly, and when it passes through the injection pipe, it is adsorbed by the adsorption component through the docking plate. While the injection pipe is moving, the injection pump injects liquid into the bag to increase the weight of the bag. After covering the net, the bag hangs on both sides of the tea tree to fix the tea tree after covering the net.

[0026] S2: When the net is closed, the injection pipe is connected to the spray pipe. The liquid-containing capsule slides along the guide rail assembly. When it passes through the injection pipe, it is adsorbed by the adsorption component through the docking plate. After the injection pipe moves in the opposite direction, it squeezes the capsule, so that the liquid in the capsule is sprayed outward through the spray pipe onto the uncollected shade net. While collecting, the shade net vibrates, which vibrates the liquid on the net through the gaps onto the tea trees to achieve irrigation.

[0027] The beneficial effects of the present invention are: by setting water-flushing bladders on the shade net and injecting water into the bladders during the net covering process, the bladders are fixed by their own weight, eliminating the need for manual operation, thus improving the net covering efficiency and reducing the initial weight of the shade net during winding.

[0028] At the same time, by reusing the liquid in the capsules as irrigation water when the net is harvested, the water resource utilization rate is improved, the transpiration stress of tea trees is alleviated, and the irrigation effect is enhanced.

[0029] In addition, the automatic switching between injection and drainage modes is achieved by linking the three-way valve with the drive push rod, which improves the efficiency of the netting and the accuracy of the control of the capsule. Attached Figure Description

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-6 .

[0037] A tea-picking netting device includes a roller 1, a roller frame 2, and a shade net 3 wound on the roller 1. The roller 1 is rotatably mounted on the roller frame 2, and the roller frame 2 is fixed on a traveling mechanism. This is the prior art of netting devices, and will not be described in detail here. For example, Japanese Patent No. JP6030500B2 discloses a netting device mounted on a traveling mechanism.

[0038] The shade net 3 is wound around the roll 1. A counterweight can be fixedly installed at the beginning of the shade net 3, so that when the shade net 3 is covering the tea tree, its front end can be fixed by hanging it on the front end of the tea tree through the counterweight.

[0039] The shade net 3 has several symmetrically arranged pockets 301 on both sides. The pockets 301 are equidistantly spaced, spaced 1-3m apart along the straight direction of the shade net 3. The specific spacing can be adjusted adaptively according to the actual laying conditions of the tea trees. Each pocket 301 is a telescopic pocket, comprising a fixing part 303 fixedly connected to the shade net 3, a telescopic part 304, and a connecting plate 302. Figures 5-6 As shown, the fixing part 303 is fixedly connected to the side of the shade net 3 by a short rope, and the telescopic part 304 extends along the side away from the shade net 3 and is fixed to the docking plate 302. The telescopic part 304 is made of deformable plastic. After the capsule 301 is filled with liquid, it expands through the telescopic part 304 to achieve the water-filled expansion of the capsule 301; at the same time, the capsule 301 is compressed when the telescopic part 304 is squeezed.

[0040] The roller frame 2 is symmetrically provided with guide rail assemblies 4 on both sides to guide the bladders 301 on both sides, such as Figures 1-3 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 shade net 3 for the shade 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 for the bladder 301 to slide and accommodate, so that when the shade net 3 is being pulled up and covered, the bladder 301 can slide along the groove in the upper and lower grooves.

[0041] The gap groove 403 between the upper guide rail 402 and the lower guide rail 401 allows the rope connecting the bladder 301 to the side of the sunshade net 3 to pass through. When the telescopic part 304 is squeezed by the docking plate 302, the fixing part 303 abuts against the wall on one side of the gap groove 403 with the upper guide rail 402 and the lower guide rail 401, thereby limiting the lateral movement of the bladder 301. The side of the upper guide rail 402 and the lower guide rail 401 away from the sunshade net 3 is in an open state, which allows the docking plate 302 of the bladder 301 to cooperate with the components on the roller frame 2, thereby realizing the telescopic movement of the bladder 301 through the docking plate 302.

[0042] The roll frame 2 is movably provided with an injection tube 201 for injecting liquid into the capsule 301. An adsorption element 202 is provided at one end of the injection tube 201 facing the capsule 301. The adsorption element 202 is preferably a magnet, and the docking plate 302 is preferably a ferromagnetic metal plate with ferromagnetic adsorption force. When the adsorption element 202 approaches or contacts the capsule 301, the injection tube 201 and the capsule 301 are docked through the adsorption element 202 and the docking plate 302.

[0043] The capsule 301 has a liquid injection port 305 on one side of the docking plate 302. The liquid injection port 305 is located 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 5 As shown, initially, the valve core 306 is placed inside the injection port 305 to block the injection port 305. When the end of the injection tube 201 is magnetically attracted to the docking plate 302 by the adsorption member 202, the injection tube 201 pushes against the valve core 306 inside the injection port 305, and the spring 307 is stretched, so that the end of the injection tube 201 is placed inside the bladder 301.

[0044] The side wall of the end of the injection tube 201 is evenly provided with a plurality of injection holes 206. When it is placed inside the bladder 301, liquid can be injected into the bladder 301 through the injection holes 206. One end of the injection tube 201 is engaged with the bladder 301, and the other end is connected to the injection pump and the injection tube 102 respectively through the three-way valve 101. The injection tube 201 is connected to the three-way valve 101 through a flexible tube. The three-way valve 101 is a three-way solenoid valve. By electromagnetically controlling the flow direction of the valve body, the injection tube 201 can be connected to the injection pump or the injection tube 102 respectively.

[0045] Specifically: during netting, the three-way valve 101 controls the injection pump to connect with the injection pipe 201, so that the injection pipe 201 injects liquid into the bladder 301 when it is moving; during netting, the three-way valve 101 controls the spray pipe 102 to connect with the injection pipe 201, so that the injection pipe 201 moves in the opposite direction to squeeze the bladder 301, and the liquid in the bladder 301 is discharged through the spray pipe 102 under the compression of the telescopic part 304.

[0046] The spray pipe 102 is located at the front end of the roll frame 2, and its spraying direction is set towards the front middle of the shade net 3, so that the sprayed liquid can be sprayed onto the surface of the shade net 3 that has not been collected. Subsequently, when the shade net 3 is rolled up for collection, the surface water is dropped onto the surface of the tea leaves through vibration and compression, so as to achieve irrigation.

[0047] In this embodiment, the valve core 306 structure on the bladder 301 can also be replaced by a two-way check valve. The flow of liquid is controlled unidirectionally by the direction of liquid flow. That is, when the bladder 301 is squeezed, the liquid in the bladder 301 flows to the injection tube 201 through the two-way check valve. When the injection tube 201 is injecting liquid, the liquid is injected into the bladder 301 through the two-way check valve.

[0048] like Figures 3-4As shown, the injection tube 201 has a vertically upward guide rod 203 in the middle of its rod body, and the axis of the injection tube 201 is always spatially perpendicular to the plane of the docking plate 302 of the bladder body 301; the roll frame 2 has a guide groove 204 that cooperates with the guide rod 203, the guide groove 204 is a long groove, and its direction is inclined from one side of the roll 1 to the side away from the roll 1 and the shade net 3; the guide rod 203 is provided with a guide surface that fits against the two side walls of the guide groove 204, so that the guide rod 203 slides along the guide groove 204.

[0049] The roll frame 2 is provided with a drive push rod 205 that drives the guide rod 203 to move along the guide groove 204. The drive push rod 205 can be an electric push rod. When the drive 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 element 202 and the docking plate 302.

[0050] like Figure 3 and Figure 4 The state shown is the state when the shade net 3 is being collected. The injection pipe 201 is connected to the spray pipe 102. At this time, the docking plate 302 is adsorbed and docked with the adsorption component 202. When the shade net 3 is being wound and rolled up, the drive push rod 205 pushes the guide rod 203 to slide to the side of the drum 1, so that the end of the injection pipe 201 squeezes the bladder 301, thereby causing the liquid in the bladder 301 to be discharged through the spray pipe 102. After further winding, the bladder 301 is automatically detached from the injection pipe 201 by the traction force of the rope on the shade net 3 and is wound and collected. Then the drive push rod 205 retracts to the initial position, so that the injection pipe 201 returns to the initial state to wait for the next bladder 301 to pass.

[0051] Conversely, during the netting process, the injection pipe 201 is connected to the injection pump, and the guide rod 203 is positioned at the end of the guide groove 204 near the drum 1. Subsequently, when the bladder 301 of the shade net 3 passes through the injection pipe 201, it cooperates with the adsorption element 202 on the injection pipe 201 for adsorption. At the same time, the drive push rod 205 retracts, causing the guide rod 203 to slide in the opposite direction along the guide groove 204. While the injection pipe 201 slides, it injects liquid into the bladder 301. When the guide rod 203 is limited by the end of the guide groove 204, the bladder 301 automatically detaches from the injection pipe 201 by the traction of the rope on the shade net 3, completing the liquid injection. Then, the injection pipe 201 is pushed to the initial position by the drive push rod 205, waiting for the next bladder 301 to pass.

[0052] A method for operating a tea-picking netting device is as follows:

[0053] S1: When covering the net, the injection pipe 201 is connected to the injection pump, the shade net 3 is discharged outward, and the bag body 301 slides along the guide rail assembly 4. When passing through the injection pipe 201, it is adsorbed by the adsorption component 202 through the docking plate 302. While the injection pipe 201 is moving, the injection pump injects liquid into the bag body 301 to increase the weight of the bag body 301. After covering the net, the bag body 301 hangs on both sides of the tea tree to fix the tea tree after covering the net.

[0054] S2: When the net is collected, the injection pipe 201 is connected to the spray pipe 102. The liquid-containing capsule 301 slides along the guide rail assembly 4. When it passes through the injection pipe 201, it is adsorbed by the adsorption component 202 through the docking plate 302. After the injection pipe 201 moves in the opposite direction, it squeezes the capsule 301, so that the liquid in the capsule 301 is sprayed outward through the spray pipe 102 onto the uncollected shade net 3. While collecting, the shade net 3 vibrates, vibrating the liquid on the net through the gaps onto the tea trees to achieve irrigation.

[0055] In this embodiment, the controller can connect and control the above-mentioned drum, three-way valve, injection pump and drive push rod to realize the automated control of the entire tea picking and covering netting device. At the same time, various sensors can also be set on the guide rail assembly 4 of the drum frame 2 to detect the passage status of the bag 301.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
