[0038] like Figure 1-Figure 14As shown, the present invention provides a technical solution: an irrigation device for forestry seedling cultivation, comprising a base plate 1, the base plate 1 is used to provide support for a mixing tank 201, and a circular groove is arranged on the upper surface of the base plate 1, the circular groove is designed according to the radius of the mixing tank 201, and is used to limit the mixing tank 201 on the top of the base plate 1, so as to prevent the mixing tank 201 from rocking back and forth on the upper surface of the base plate 1 due to the uneven road surface when the staff pushes the device forward through the handle on one side of the base plate 1, and the base plate 1 is connected to the auxiliary plate 101 by a hinge, the hinge is a prior art, and will not be described in detail here, and the setting of the hinge can cause the auxiliary plate 101 to flip, it should be noted that the auxiliary plate 101 and the lower surface of the base plate 1 They are all equipped with brake universal wheels, which are convenient for the staff to move the device and brake after reaching the working area, so as to carry out seedling cultivation operations on seedlings in different areas. Since the brake universal wheels are prior art, they will not be described in detail here. The mixing and stirring component 2 is arranged at the top of the base plate 1, and is used to mix the fertilizer and water for forestry seedling cultivation, and is easy to disassemble and replace. The root interception component 3 is arranged at the top of the auxiliary plate 101 on one side of the base plate 1, and is used to adjust the irrigation depth of forestry seedling cultivation so as to irrigate the roots of seedlings at different depths. The fixed irrigation component 4 is arranged above the base plate 1 and the auxiliary plate 101, and is used to connect the mixing tank 201 and the fixed cylinder 303, and transport the growth fluid required for forestry seedling cultivation.

[0039] like Figure 1-14As shown, in the embodiment of the present application, a hook 102 is symmetrically provided at the top of the base plate 1, and a hanging rod 103 is symmetrically provided at the top of the auxiliary plate 101, and a convex column 104 is provided on the side of the hanging rod 103 facing the upper surface of the auxiliary plate 101, and the hanging rod 103 is matched with the hook 102. Specifically, when performing forestry seedling operations, the staff pushes the device to the working area. At the beginning, the auxiliary plate 101 is horizontally placed with the base plate 1, and the convex column 104 on one side of the hanging rod 103 on the auxiliary plate 101 is inserted into the circular hole on the upper surface of the base plate 1, and the circular hole is matched with the convex column 104, which is used to fix the hanging rod 103 above the auxiliary plate 101, and the root cutting component 3 is placed on the upper surface of the auxiliary plate 101, and the upper surface of the auxiliary plate 101 is also used to accommodate the outlet pipe 402. After reaching the vicinity of the seedling, the root cutting component 3 is removed from the auxiliary plate 10 1 and inserted into the soil beside the sapling, then, the protruding column 104 on the hanging rod 103 is pulled out from the circular hole on the base plate 1, and the hanging rod 103 is swung. While swinging the hanging rod 103, the auxiliary plate 101 is folded. During the folding process of the auxiliary plate 101, the hanging ring at one end of the hanging rod 103 is sleeved on the hook 102, so that the hanging rod 103 will support the auxiliary plate 101, so that the auxiliary plate 101 and the base plate 1 are in a vertical state to reduce the footprint of the device, and at the same time, the water outlet pipe 402 is freed so that its water outlet end does not need to face the ground. It should be noted that the hanging rod 103 is swung around the outer side of the splint on the upper surface of the auxiliary plate 101 by the rotating rod, and the opening of the hook 102 faces the mixing tank 201. When the back is facing the auxiliary plate 101, the hanging rod 103 can be firmly locked in the hook 102 when the auxiliary plate 101 is tilted forward.

[0040] like Figure 1-14As shown, in the embodiment of the present application, the mixing and stirring component 2 includes a mixing tank 201, which is located at the top of the substrate 1, and a fixed shaft 209 is arranged on the inner side of the middle part of the mixing tank 201, and a locking column 205 is arranged on the inner wall of the top of the fixed shaft 209, and the top of the locking column 205 is connected to the output end of the motor. Specifically, the motors of the present application are connected to the external power supply and controlled by the control system. The mixing tank 201 consists of a tank body and a tank cover. The tank cover and the tank body are snap-fitted, and two feeding ports are centrally symmetrically arranged on the tank cover for the delivery of water and fertilizer for seedling cultivation. Before performing the injection operation, the internal parts need to be installed first, and then the tank cover is covered. It should be noted that the fixed shaft 209 is rotatably arranged in the mixing tank 201, and a part of the upper end of the fixed shaft 209 is located on the tank cover, so that under the cooperation of the tank body and the tank cover, the fixed shaft 209 is limited. The fixed support is in the middle of the mixing tank 201, and a notch matched with the locking column 205 is provided at the top of the fixed shaft 209. The locking column 205 consists of two parts, one part is a cylinder, whose radius is consistent with the fixed shaft 209, and the length is the distance between the top of the fixed shaft 209 and the upper surface of the tank cover, and the other part is a hexagonal prism, which is matched with the notch of the inner wall of the top of the fixed shaft 209, and the lengths of the two affect each other. Therefore, when the motor drives the locking column 205 to rotate, the locking column 205 can synchronously drive the fixed shaft 209 to rotate through the hexagonal prism. It should be noted that the lower part of the locking column 205 can also be other styles such as a triangular prism and a cross column, but it cannot be a cylinder. Because if it is a cylinder, when the motor drives the locking column 205 to rotate, the locking column 205 will only rotate inside the fixed shaft 209, and cannot drive the fixed shaft 209 to rotate synchronously.

[0041] like Figure 1-14As shown, in the embodiment of the present application, the outer wall of the fixed shaft 209 is symmetrically provided with a limit block 208 on the central axis, and the outer wall of the limit block 208 is provided with a stirring shaft 207 and a circular plate 206, and the circular plate 206 is located at the upper and lower ends of the stirring shaft 207. Specifically, under the action of the limit block 208, the stirring shaft 207 and the circular plate 206 can be limited, so that when the fixed shaft 209 rotates, the stirring shaft 207 and the circular plate 206 can be synchronously driven to rotate, and the circular plate 206 is located at the upper and lower ends of the stirring shaft 207, and the upper surface of the circular plate 206 at the top is not in direct contact with the lower surface of the tank cover. The length of the limit block 208 is much higher than the thickness of the circular plate 206, so that the synchronous limit of the stirring shaft 207 and the circular plate 206 can be satisfied, and the limit block 208 located below also plays a role in positioning the fixed shaft 209. When the fixed shaft 209 is installed, When the bottom end of the lower limit block 208 contacts the bottom end of the inner wall of the mixing tank 201, the fixed shaft 209 is rotated and installed in the circular groove at the bottom end of the inner wall of the mixing tank 201. The limit block 208 is used to determine whether the fixed shaft 209 is completely installed in the mixing tank 201. It should be noted that during installation, the stirring shaft 207 should be placed between the circular plates 206. After the fixed shaft 209 is installed, the limit block 208 is aligned with the limit grooves on the circular plate 206 and the stirring shaft 207, and then the circular plate 206 and the stirring shaft 207 are inserted. The inner walls of the circular plate 206 and the stirring shaft 207 are both provided with limit grooves that are compatible with the limit block 208, and the limit grooves run through the upper and lower ends of the circular plate 206 and the stirring shaft 207. The space between the brush plates 204 can accommodate the stirring shaft 207 and the stirring blades 203 on its outer wall.

[0042] like Figure 1-14As shown, in the embodiment of the present application, a plurality of round rods 210 are arranged on the outer wall of the circular plate 206, and a circular ring 202 is arranged on the other end of the circular rod 210. A brush plate 204 is arranged on the outer wall of the circular ring 202, and one side of the brush plate 204 is in contact with the inner wall of the mixing tank 201. A stirring blade 203 is arranged on the outer wall of the stirring shaft 207. Specifically, under the action of the brush plate 204, the inner wall of the mixing tank 201 can be cleaned, and the stirring blade 203 can mix the liquid inside the mixing tank 201, so that the water and fertilizer inside the mixing tank are dissolved together faster. The round rod 210 is used to connect the circular plate 206 and the circular ring 202, and the surface of the round rod 210 is smooth, so that it will not adhere to the material projected into the mixing tank 201. The stirring blades 203 are arranged upward in a spiral. When the stirring shaft 207 rotates, it can drive the stirring blades 203 to perform horizontal circular motion, and can simultaneously stir the growth liquid at different water levels in the mixing tank 201. It should be noted that the mixing tank Two feeding ports are arranged at the top of 201, one for projecting water and the other for projecting fertilizer required for growth. After water and fertilizer are projected into the mixing tank 201 in a certain proportion, the control system is used to start the motor, and the motor will drive the fixed shaft 209 to rotate by driving the locking column 205. While the fixed shaft 209 rotates, the limit block 208 drives the stirring shaft 207 and the circular plate 206 to rotate synchronously. When the stirring shaft 207 and the circular plate 206 rotate, they can drive the stirring blade 203 to stir the liquid in the mixing tank 201, thereby accelerating the mixing, and the circular plate 206 drives the brush plate 204 on one side of the ring 202 through the round rod 210 to scrape the inner wall of the mixing tank 201 to prevent the fertilizer from sticking to the inner wall of the mixing tank 201, and at the same time plays the function of cleaning the inner wall of the mixing tank 201. However, if the saplings are simply watered, the motor does not need to be started. When the growth liquid mixed with water and fertilizer needs to be watered, the motor will be started.

[0043] like Figure 1-14 As shown, in an embodiment of the present application, the fixed irrigation component 4 includes a water inlet pipe 403, which is located inside the mixing tank 201, and a water pump 401 is provided at one end of the water inlet pipe 403, and a valve 404 is provided on one side of the water pump 401, and the water pump 401 and the valve 404 are connected by an interconnecting pipe 405, and a water outlet pipe 402 is provided at the other end of the valve 404. Specifically, the valve 404 is installed behind the water pump 401 to facilitate the adjustment of the water output of the water pump 401 to prevent overload caused by excessive water output. In addition, the valve 404 is installed behind the water pump 401 to simulate different water use conditions during debugging and adjust certain parameters. One end of the water inlet pipe 403 extends to the inner wall of the mixing tank 201 and coincides with its inner wall. This design can ensure that the water inside the mixing tank 201 flows out normally without affecting the normal rotation of the brush plate 204.

[0044] like Figure 1-14As shown, in the embodiment of the present application, one end of the water outlet pipe 402 passes through the auxiliary plate 101 to the outside, a limiting ring 407 is provided on the outer wall of the water outlet pipe 402, a fixing sleeve 406 is provided on the outer wall of the limiting ring 407, a merging pipe 408 is provided on the inner wall of the fixing sleeve 406, a sprinkler head 410 is provided on one end of the merging pipe 408, and a retaining ring 409 is provided on the outer wall thereof. Specifically, a limiting ring 407 is fixedly provided on the outer wall of the water outlet pipe 402, and the existence of the limiting ring 407 prevents the fixing sleeve 406 from detaching from the outer wall of the water outlet pipe 402, and limits the water outlet port of the water outlet pipe 402 to below the auxiliary plate 101, so that when the pipe is being piped, When connecting the pipes, it is convenient for the staff to find the water outlet in time, instead of being randomly curled on the upper surface of the auxiliary plate 101, thereby increasing the staff's searching time. The design of the present application improves the speed of pipe connection, and the fixing sleeve 406 and the limiting ring 407 are rotatably connected, that is, the fixing sleeve 406 rotates around the limiting ring 407. When connecting the pipes, the staff drags the fixing sleeve 406 to make it penetrate into the center of the push-pull rod 304. After the fixing sleeve 406 enters the center of the push-pull rod 304, the fixing sleeve 406 is aligned with the center of the merged pipe 408, and the fixing sleeve 406 is rotated to make it rotate along the merged pipe. The outer wall of 408 faces downward, and the fixing sleeve 406 and the merging pipe 408 are threadedly connected. When the fixing sleeve 406 rotates, the outlet pipe 402 will not rotate with it. After the lower surface of the fixing sleeve 406 contacts the upper surface of the retaining ring 409, the pipeline connection work is completed. It should be noted that the area where the inner wall of the fixing sleeve 406 contacts the limiting ring 407 is smooth, and a ring groove that matches the limiting ring 407 is separately provided, while the area in contact with the merging pipe 408 is provided with a thread on its inner wall, and the outer wall of the merging pipe 408 is provided with a threaded groove that matches the fixing sleeve 406. After the installation of pipe 408 is completed, the water outlet end of the outlet pipe 402 enters the inner wall area of ​​the merging pipe 408 to reduce the seepage of the growth liquid during the circulation process. When the seedling growth liquid is transported, the growth liquid flows from the mixing tank 201 to the water inlet pipe 403, the water pump 401 is started, and the valve 404 is adjusted. The water pumps 401 of the present application are connected to an external power supply and controlled by a control system. The growth liquid in the water inlet pipe 403 flows through the interconnecting pipe 405 to the outlet pipe 402, and is passed to the sprinkler head 410 at the outlet pipe 402. The growth liquid is sprayed out from the nozzle of the sprinkler head 410 to water the seedlings.

[0045] like Figure 1-14As shown, in the embodiment of the present application, the root interception assembly 3 includes a fixed cylinder 303, the fixed cylinder 303 is located above the auxiliary plate 101, and a plurality of irrigation grooves 311 are arranged on the fixed cylinder 303. A mud guard 305 is arranged between the inner walls of the irrigation grooves 311 on both sides, and a fixing rod 309 is arranged inside the mud guard 305. The fixing rod 309 is located on the inner walls of the irrigation grooves 311 on both sides. The mud guard 305 is provided with an arch block 308 on one side facing the inner wall of the fixed cylinder 303, and the mud guard 305 and the irrigation grooves 311 are both provided with a guide slope 310 at the bottom. Specifically, before the sapling irrigation operation is performed, the fixed cylinder 303 needs to be inserted into the soil. During the insertion process, And ensure that the fixed tube 303 is close to the root of the sapling. The bottom of the fixed tube 303 is threadedly connected with a drill bit 306 for easy disassembly and replacement. The design of the drill bit 306 facilitates the fixed tube 303 to enter the soil better and reduces the force required for it to enter the soil. The fixed tube 303 area near the top of the drill bit 306 is provided with a number of leakage holes. The leakage holes are arranged in a circle and are used to discharge the growth liquid sprinkled into the fixed tube 303 when the sprinkler head 410 sprays water. The length of the fixed tube 303 is adjusted according to the height of the root of the sapling to ensure that its length is higher than the height of the root of the sapling, so as to meet the irrigation operation. In the process of the fixed tube 303 being inserted into the soil , the soil enters the guide slope 310 at the bottom of the irrigation trough 311, and then the fixed cylinder 303 continues to fall and under the action of gravity, the soil pushes up the mud guard 305, and because the bottom of the mud guard 305 is also provided with a guide slope 310, the soil will leave the area of ​​the irrigation trough 311 along the guide slope 310, and the lower surface of the mud guard 305 is in contact with the bottom end of the irrigation trough 311, so as to prevent the soil from entering the fixed cylinder 303 through the irrigation trough 311 during the process of the fixed cylinder 303 being inserted into the soil. An arch block 308 is provided on one side of the mud guard 305, and the arch block 308 is an isosceles trapezoid, and its edges are set to be rounded, so that the ring 409 can be moved along The outer wall of the arch block 308 moves. It should be noted that although the fixing tube 303 is inserted into the soil, it does not have to be completely immersed. Instead, the root part of the sapling is divided into three parts: the surface layer, the middle layer, and the bottom layer. The surface layer refers to the surface layer, that is, the surface of the soil, while the middle layer and the bottom layer refer to the root system of the sapling in the soil. The middle layer and the bottom layer are respectively adapted to the two layers of irrigation grooves 311 on the fixing tube 303. When the fixing tube 303 is inserted into the soil, after the irrigation grooves 311 are matched with the middle and bottom layers of the root system, the insertion operation of the fixing tube 303 is stopped. At this time, a part of the fixing tube 303 near the top is still exposed above the soil.

[0046] like Figure 1-14As shown, in the embodiment of the present application, a drill bit 306 is provided at the bottom of the fixed cylinder 303, and a fixing ring 302 is provided on its outer wall, a tripod 301 is provided on the outer wall of the fixing ring 302, and a vertical groove 307 is provided on the inner wall of the fixed cylinder 303. The vertical groove 307 and the irrigation groove 311 are arranged in a staggered manner, and a push-pull rod 304 is provided on the inner wall of the vertical groove 307. Specifically, the tripod 301 and the fixing ring 302 are an integrated adaptive structure. The tripod 301 is used to support the fixed cylinder 303 when it is inserted into the soil, and the fixing ring 302 is used to limit the fixed cylinder 303 to avoid angle deviation during the insertion process, thereby damaging the roots of the saplings. When performing root irrigation operations, the sprinkler head 410 is installed in advance, and each pipeline is connected. The push-pull rod 304 is connected by a joint to ensure that the connection is firm and well sealed. The vertical groove 307 arranged on the inner wall of the fixed cylinder 303 is adapted to the push-pull rod 304 and is used to limit it, and the push-pull rod 304 moves along the vertical groove 307. The vertical groove 307 and the irrigation groove 311 are staggered, so that the translation of the push-pull rod 304 will not affect the irrigation groove 311. The push-pull rod 304 is aligned with the vertical groove 307, and the staff pushes the push-pull rod 304 downward. During the downward movement of the push-pull rod 304, the ring 409 is simultaneously driven to move downward. During the downward movement of the ring 409, it will gradually contact the arch block 308. After the ring 409 contacts the arch block 308, it moves along the hypotenuse of the arch block 308, and at the same time, the arch block 308 is pressed. 08 is squeezed, and after the arch block 308 is squeezed by the ring 409, it will drive the fender 305 to rotate around the fixed rod 309. The fixed rod 309 is fixedly set on the irrigation groove 311. During the rotation of the fender 305, the soil on the outside can be pushed away, thereby freeing up a part of the space. When the ring 409 enters the vertical side of the arch block 308, the downward movement of the push-pull rod 304 is stopped. At this time, the water spray port of the sprinkler head 410 below the ring 409 is facing the gap in the irrigation groove 311, and the growth liquid will be sprayed from the water spray port, thereby irrigating the roots at different depths, and the guide slope 310 can facilitate the flow of the growth liquid and play a certain diversion role. After the irrigation is finished, the staff pulls the push-pull rod 304 upwards , so that the arch block 308 will lose the squeezing force applied by the ring 409, and then the arch block 308 will drive the fender 305 to return to its original position under the vertical action. It should be noted that before the push-pull rod 304 is pushed and pulled, the depth to which the push-pull rod 304 needs to be moved down should be tested before the fixed tube 303 is inserted into the soil, and when the corresponding depth is reached, a scale mark is made on the outer wall of the push-pull rod 304. When the staff moves the push-pull rod 304 downward, as long as they see that the scale mark coincides with the top surface of the fixed tube 303, they know that the ring 409 has reached the corresponding position. The push-pull rod 304 is located on the outer wall of the ring 409, and the two are fixedly connected, and a filter plate is provided on the inner wall of the merging tube 408.The filter plate is located below the position of its outlet pipe 402 in the merging pipe 408. When performing irrigation operations, if the middle layer is to be irrigated, the ring 409 will only squeeze the upper arch block 308. If the bottom layer is to be irrigated, the ring 409 will first squeeze the upper arch block 308 and release it, and then squeeze the lower arch block 308 to achieve irrigation operations. If the surface layer needs to be irrigated, there is no need to insert the fixed cylinder 303 into the soil. The push-pull rod 304 can be directly removed from the vertical groove 307 on the inner wall of the fixed cylinder 303, and the surface of the seedling can be irrigated. After the irrigation operation is completed, the fixed cylinder 303 can be taken out of the soil or kept inserted into the soil. If it is kept inserted into the soil, there are two situations. One is One is that the push-pull rod 304 is removed. If it rains, the rainwater will enter the fixed tube 303 and be discharged from the water leakage hole near the top of the drill bit 306, thereby replenishing moisture to the soil where the sapling is located. The other is that the push-pull rod 304 is still placed in the fixed tube 303. When the push-pull rod 304 exists, if the position where the ring 409 stays is the vertical edge of any one of the arch blocks 308, when it rains, the rainwater will flow out from the water spray port of the sprinkler head 410 and irrigate the corresponding middle or bottom layer of the roots. If the ring 409 does not stay in the area of ​​the irrigation trough 311, the rainwater will be stored in the sprinkler head 410 and the merging tube 408, as well as the inner wall area of ​​the fixed tube 303 above it. The filter plate inside the merging tube 408 can filter impurities, thereby preventing the sprinkler port from being blocked.

[0047] When carrying out irrigation operations for forestry seedlings, first remove the fixed tube 303, rotate the auxiliary plate 101, support it with the hanging rod 103, set up the tripod 301 and the fixed ring 302, insert the fixed tube 303 into the soil where the roots of the seedlings are located, and the staff drags the fixed sleeve 406 to connect it with the merging tube 408. The staff drives the push-pull rod 304 to move downward so that the abutment ring 409 contacts the vertical side of the arch block 308, so that the water outlet of the sprinkler head 410 can correspond to the gap leaked by the irrigation trough 311. After that, the growth liquid required for the seedlings is poured into the mixing tank 201 according to a certain water-fertilizer ratio, and the motor is started. The motor is locked through the locking column 205 drives the fixed shaft 209 to rotate. During the rotation of the fixed shaft 209, the limit block 208 is used to synchronously drive the stirring shaft 207 and the circular plate 206 to rotate. During the rotation of the stirring shaft 207, the stirring blade 203 is driven to mix the water and the fertilizer. The circular plate 206 drives the brush plate 204 on the outside of the ring 202 through the round rod 210 to clean the inner wall of the mixing tank 201. After the water and fertilizer in the mixing tank 201 are completely mixed, the water pump 401 is started and the valve 404 is opened. The growth liquid will start from the water inlet pipe 403, pass through the interconnecting pipe 405 and the water outlet pipe 402, flow to the sprinkler head 410, and be sprayed out from the sprinkler port to irrigate the roots of the seedlings.

Irrigation operations are carried out at the roots of the seedlings, so that irrigation operations can be carried out at positions of different depths of the roots, thereby saving water resources and avoiding the phenomenon of over-irrigation of shallow roots and lack of water in deep layers. The outlet pipe 402 and the sprinkler head 410 can be quickly connected through the cooperation of the fixing sleeve 406 and the merging pipe 408, and can be quickly assembled and disassembled on site, which is convenient for adjustment according to the layout and growth conditions of the seedling raising area, shortening the preparation time of the staff before implementing the irrigation operation and improving work efficiency. The internal parts of the mixing tank 201 are loaded and unloaded by mutual limiting operations. The locking column 205 cooperates with the fixed shaft 209, and the limit block 208 cooperates with the circular plate 206 and the stirring shaft 207, so that the stirring mechanism is easy to disassemble and replace, thereby improving the practicability of the device.
