Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forest tree nutrition supply, in particular to a precise paulownia tree nutrition supply device and an operation method thereof. BACKGROUND

[0002] Paulownia trees grow fast, are widely distributed, have good material quality, and have multiple uses, are suitable for roadside greening and patch afforestation, and in recent years, many areas have planted a large number of paulownia trees, and have also engaged in paulownia and crop intercropping and planted paulownia trees in square field forest nets, and some places have gradually developed mountain afforestation. In the growth process of paulownia trees, the forest rangers cannot do without hard work, and usually in the dry season, irrigation devices are placed around the trees to irrigate the trees regularly. The existing irrigation devices are divided into three types:

[0003] One is flood irrigation, which relies on a water pump to pump water to the surface of the soil where the trees are planted, and the water solution is allowed to penetrate into the soil and be absorbed by the roots. Although this method can irrigate a large area, a part of the water solution far from the roots cannot be absorbed, another part evaporates on the ground, and only a small part reaches the roots and is absorbed, causing waste of water resources;

[0004] Another is drip irrigation, which slowly drips water into the soil through a drip head. Although this irrigation method can accurately control the amount of drip irrigation water and fertilizer, a part of the liquid that falls on the soil surface will still evaporate, especially in dry and hot areas, which is particularly inappropriate;

[0005] There is also a sprinkler irrigation method, which sprays water in the form of fine droplets on the soil surface or plant leaves. The advantage of this method is that the spraying range is large, with a spraying radius of about 5 meters, but the irrigation accuracy is low, and the water droplets sprayed on the leaves eventually fall on the ground and are partially evaporated, causing waste.

[0006] Based on the above, based on the demand for supply accuracy and supply range of the existing paulownia tree nutrition supply device, and the technical cost of realizing this function in the prior art, a supply device that can overcome resource waste and has high nutrition supply accuracy is needed.

[0062] When the first adjusting assembly 11 pushes the piston 1003 to move up, the air in the air exchange box 1001 is extruded, the air in the air exchange box 1001 flows into the shell 201 through the second vent hole 1002 and the first vent hole 203, the air pressure in the shell 201 is increased, the spray head 204 is pushed to move forward, until the nozzle 205 at the front end of the spray head 204 completely protrudes out of the shell 201, the movement of the spray head 204 stops, at this time, the interface 206 on the spray head 204 corresponds to the connector 202, the water solution in the arc-shaped flow guide pipe 3 enters the spray head 204 through the connector 202 and the interface 206, and finally is sprayed out from the nozzle 205, the Paulownia trees surrounded in the arc-shaped flow guide pipe 3 are sprayed with water, the dust attached to the surface of the Paulownia trees is washed away, the normal photosynthesis of the Paulownia trees is ensured, and the growth of the Paulownia trees is beneficial;

[0063] The working mode and advantages of the device are further illustrated in combination with the prior art as follows:

[0064] In the basic logic and concept expressed above, the precise nutrient supply device for Paulownia forest provided by the present application is significantly different from the prior art, which is shown as follows:

[0065] Firstly, the prior device adopts the method of opening the spray holes in the lower end surface of the arc-shaped flow guide pipe 3 to guide the water solution to the ground, or setting the spraying structure on the inner side of the arc-shaped flow guide pipe 3 to realize the irrigation of the forest by relying on the penetration of the water solution itself. The present application adopts the cooperation of the arc-shaped flow guide pipe 3, the supply pipe 6 and the lead-in pipe 8, and after the lead-in pipe 8 is inserted into the soil, the water source is guided to the ground below for irrigation, which avoids the evaporation on the ground and saves the water resources. At the same time, after the lead-in pipe 8 is inserted into the soil, it is closer to the Paulownia root, which is beneficial to the faster absorption of the water solution nutrients by the tree, especially for the Paulownia seedlings in the early stage, which accelerates the growth speed;

[0066] Secondly, the supply pipe 6, the adapter pipe 7 and the lead-in pipe 8 provided by the present application not only have the function of conveying the water solution, but also support the arc-shaped flow guide pipe 3, which is equivalent to a support frame. The adapter pipe 7 is L-shaped and forms a cuboid with the arc-shaped flow guide pipe 3 and the supply pipe 6 at both ends, which enhances the firmness and stability of the connection between the arc-shaped flow guide pipe 3 and the supply pipe 6;

[0067] Thirdly, the present application sets the first adjusting assembly 11. When irrigation is needed, the first adjusting assembly 11 moves upwards to open the lower off-cone head 9. When irrigation is not needed, the first adjusting assembly 11 moves downwards to automatically close the off-cone head 9, which avoids the large particles in the outside environment from entering the supply pipe 6 through the lead-in pipe 8. Moreover, after the off-cone head 9 is inserted into the soil, a water storage groove is left below the lead-in pipe 8. When the off-cone head 9 moves upwards to open the opening at the lower end of the lead-in pipe 8, the water storage groove plays a good buffering role, which avoids the phenomenon of back suction when the water pump stops working, which causes the soil to be sucked into the lead-in pipe 8 and causes blockage;

[0068] Fourthly, during the upward movement of the first adjusting assembly 11, the gas in the connecting rod 1101 is compressed by the mounting pin 1103, so that the air in the connecting rod 1101 enters the shell 201, so that the spray head 204 drives the nozzle 205 to protrude from the shell 201. The water solution in the arc-shaped flow guide pipe 3 enters the spray head 204 through the joint 202 and the interface 206, and is sprayed out through the nozzle 205, which cleans the dust on the surface of the Paulownia tree, avoids the influence of the dust on the photosynthesis of the Paulownia tree, and promotes the growth of the Paulownia tree;

[0069] To sum up, the present application adopts a completely different nutrition supply mode from the prior art, and the device has the advantages of easy manufacturing and low cost by using the first adjusting assembly 11 and the open-and-close cone head 9, effectively solving the problems of resource waste and inability to realize precise supply in the use process of the supply device in the prior art.

[0070] Specifically, the operation method of the precise nutrition supply device for Paulownia trees in the present application includes the following steps,

[0071] S1: Assemble the supply device, fit the arc-shaped flow guide pipe 3 through the end boss with the circular groove at the end of another arc-shaped flow guide pipe 3, and then install the corresponding mounting ears 1 on the two arc-shaped flow guide pipes 3 together through bolts, so that the arc-shaped flow guide pipes 3 are arranged around the Paulownia trees;

[0072] S2: Install the supply device, press the arc-shaped flow guide pipe 3 by hand or a pressing tool, and insert the inlet pipe 8 at the lower end of the arc-shaped flow guide pipe 3 into the soil around the Paulownia trees;

[0073] S3: Start the supply device, connect the water inlet pipe 5 on the arc-shaped flow guide pipe 3 with the output end of the water pump, and then start the water pump to supply water into the arc-shaped flow guide pipe 3, and the water solution enters the supply pipe 6 through the arc-shaped flow guide pipe 3 and the adapter pipe 7;

[0074] Wherein, the impact force generated by the kinetic energy of the water flow opens the sealing plug 13, the first adjusting assembly 11 rises, the top end of the first adjusting assembly 11 extrudes the piston 1003 and then extrudes the air in the air exchange box 1001 into the shell 201, the nozzle 205 at the front end of the spray head 204 protrudes out of the shell 201, the interface 206 at the upper end of the spray head 204 corresponds to the joint 202, and part of the water solution in the arc-shaped flow guide pipe 3 enters the spray head 204 through the auxiliary pipe 4 and is sprayed out, thereby cleaning the dust on the surface of the Paulownia trees;

[0075] At the same time, the first adjusting assembly 11 lifts the open-and-close cone head 9 below upward, avoiding the open-and-close cone head 9 opening the lower end of the inlet pipe 8, and the water flow flows out through the lower end opening of the inlet pipe 8 for precise irrigation of the Paulownia trees;

[0076] S4: Turn off the supply device and turn off the water pump at the water source, at this time, the sealing plug 13 deflects downward again under the action of gravity and blocks the port of the adapter pipe 7, the first adjusting assembly 11 also moves downward under the action of gravity, the piston 1003 slides downward, the gas in the shell 201 returns to the air exchange box 1001 again, the spray head 204 with the nozzle 205 retracts into the shell 201, and the open-and-close cone head 9 at the bottom of the first adjusting assembly 11 also blocks the lower port of the inlet pipe 8 again.

[0080] Referring to the drawings Figure 11a , the state of the water-absorbing and expanding strip 1701 when the present embodiment has not introduced the water source is more obviously shown;

[0081] Referring to the drawings Figure 11b, more prominent show the state of the water-absorbing expansion strip 1701 when the water source is introduced, at this time the water source enters the guide pipe 8 through the water pump, the arc-shaped flow guide pipe 3, the adapter pipe 7 and the supply pipe 6, after the water flow enters the second adjusting assembly 17 through the fine hole 1706, the water-absorbing expansion strip 1701 absorbs water and expands (the expansion volume is about 90% of the original volume), and then drives the first adjusting assembly 11 to move upward, compresses the air in the connecting rod 1101, increases the air pressure of the shell 201, and drives the nozzle 205 to protrude out of the shell 201, thereby cleaning the surface of the Paulownia tree; the effect of the cleaning assembly 2 is the same as that of example 1;

[0082] At the same time, the water flows downward through the guide pipe 8, drives the impeller 1602 to rotate, and then drives the rotating shaft 1601 to rotate, the rotating shaft 1601 drives the rotating cone head 15 to rotate to loosen the surrounding soil, and finally the water flows into the soil through the circular hole 14 on the periphery of the rotating cone head 15, after irrigation is completed, the water absorbed by the water-absorbing expansion strip 1701 is slowly discharged, the water-absorbing expansion strip 1701 shrinks, the piston 1003 moves downward, the pressure of the shell 201 increases, the gas in the shell 201 returns to the air exchange box 1001 through the first air hole 203 and the second air hole 1002, the nozzle 205 is brought into the shell 201 by the nozzle 205, the water absorbed by the water-absorbing expansion strip 1701 flows out through the fine hole 1706, and finally is discharged through the circular hole 14, which cleans and dredges the circular hole 14, prevents the circular hole 14 from sucking in the soil due to the stop of the water pump, and blocks the circular hole 14 after drying;

[0083] The Paulownia forest nutrient precise supply device provided by the embodiment is significantly different from the existing one, and the differences are as follows:

[0084] Firstly, the water-absorbing expansion strip 1701 absorbs water and expands (the expansion volume is about 90%), and then drives the first adjusting assembly 11 to move upward, compresses the air in the connecting rod 1101, increases the air pressure of the shell 201, drives the nozzle 205 to protrude out of the shell 201, and cleans the surface of the Paulownia tree forest, thereby promoting photosynthesis and being conducive to the growth of the Paulownia tree forest;

[0085] Secondly, the impeller 1602 is driven to rotate, and then the rotating shaft 1601 is driven to rotate, the rotating shaft 1601 drives the rotating cone head 15 to rotate to loosen the surrounding soil, so that the water solution sprayed by the nozzle can quickly penetrate into the soil after the dust is cleaned and falls on the ground, thereby reducing the evaporation waste of the water solution;

[0086] Thirdly, after irrigation is completed, the water absorbed by the water-absorbing and swelling strip 1701 is slowly discharged, the water-absorbing and swelling strip 1701 shrinks, the discharged water flows out through the fine holes 1706, and finally flows out through the round hole 14, which washes and dredges the round hole 14, avoids the situation that the round hole 14 is blocked by soil after the soil is sucked into the round hole 14 due to the reverse suction phenomenon of the water pump when the water pump stops working, and avoids the situation that the round hole 14 is blocked by the dried soil.

[0087] In summary, the device drives the power assembly 16 to rotate by using the kinetic energy of the water flow, and then drives the rotating cone head 15 to rotate, so as to loosen the soil around the paulownia tree, which is beneficial to the penetration of the water solution in the soil and promotes the growth of the paulownia forest.
