Description

Technical Field

[0001] The present invention relates to the technical field of forest tree nutrition supply, and in particular to a device for accurately supplying nutrition to paulownia trees and an operating method thereof. Background Art

[0002] Paulownia trees grow fast, are widely distributed, have good quality, and are versatile. They are suitable for greening the surrounding areas and planting trees in large areas. In particular, in recent years, many areas have planted Paulownia trees in large numbers, intercropping with agriculture and planting them in square field forest networks. In some places, they are gradually developing into mountainous afforestation. During the growth process of Paulownia trees, they cannot be separated from the hard work of forest rangers. Usually, irrigation devices are placed around the trees in the dry season and the rainy season to regularly water the trees. 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 soil surface where trees are planted, and then wait for the water solution to penetrate into the soil and be absorbed by the roots of the trees. Although this method can irrigate a large area, in the process of the water solution penetrating into the soil, part of it is far away from the roots and cannot be absorbed, and the other part is evaporated on the ground. Only a small part reaches the roots and is absorbed, resulting in a waste of water resources;

[0004] The other is drip irrigation, which slowly drips water into the soil through a dripper. Although this irrigation method can accurately control the amount of drip irrigation water and fertilizer, some of the liquid dripping on the soil surface will still evaporate, which is particularly inappropriate in high-temperature areas during the dry season.

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

[0006] In summary, based on the requirements of the existing Paulownia forest nutrient supply device for supply accuracy and supply range, as well as the technical cost of realizing this function in the existing technology, a supply device that can overcome resource waste and has high nutrient supply accuracy is needed. For this purpose, we proposed a Paulownia forest nutrient precision supply device and its operation method. Summary of the invention

[0021] The present invention also discloses an operation method of the device for accurately supplying nutrients to paulownia trees, comprising the following steps:

[0022] S1: Assemble the supply device, fit the boss at the end of the arc-shaped flow guide pipe into the circular groove at the end of another arc-shaped flow guide pipe, and then install the corresponding mounting ears on the two arc-shaped flow guide pipes together by bolts, so that the arc-shaped flow guide pipes surround the periphery of the paulownia forest;

[0023] S2: installing the supply device, pressing the arc-shaped guide tube by hand or a pressing tool, so that the introduction tube at the lower end of the arc-shaped guide tube is inserted into the soil around the paulownia tree;

[0024] S3: Turn on the supply device, connect the water inlet pipe on the arc-shaped guide pipe with the output end of the water pump, and then start the water pump to supply water to the arc-shaped guide pipe. The aqueous solution enters the supply pipe through the arc-shaped guide pipe and the transfer pipe;

[0025] The impact force generated by the kinetic energy of the water flow opens the sealing plug, causing the No. 1 regulating component to rise. The top of the No. 1 regulating component squeezes the air in the ventilation box into the shell by squeezing the piston, causing the nozzle at the front end of the nozzle to protrude from the shell. The interface at the upper end of the nozzle corresponds to the joint, and part of the aqueous solution in the arc-shaped guide pipe enters the nozzle through the auxiliary pipe and is sprayed out to clean the dust on the surface of the paulownia wood.

[0026] At the same time, the No. 1 adjustment component lifts the lower cut-off cone upwards to prevent the cut-off cone from opening the lower end of the inlet pipe. Water flows out through the lower end opening of the inlet pipe to accurately irrigate the Paulownia trees.

[0027] S4: Turn off the supply device and the water pump at the water source. At this time, the sealing plug deflects downward under the action of gravity and blocks the port of the transfer tube again. The No. 1 regulating component also moves downward under the action of gravity, and the piston slides downward. The gas in the shell returns to the ventilation box again, and the nozzle retracts into the shell with the nozzle. The broken cone head at the bottom of the No. 1 regulating component also blocks the lower port of the inlet pipe again.

[0028] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. The present invention adopts an arc-shaped flow guide pipe, a supply pipe and an introduction pipe to cooperate. After the introduction pipe is inserted into the soil, the water source is led to the ground for irrigation, thereby avoiding evaporation on the ground and saving water resources;

[0030] 2. The present invention sets a No. 1 regulating component. When watering is required, the No. 1 regulating component moves upward to open the breaking cone head below. When watering is not required, the No. 1 regulating component moves downward to automatically close the breaking cone head, thereby preventing large particles from the outside from entering the supply pipe through the introduction pipe. After the breaking cone head is inserted into the soil, a water storage tank will be left below the introduction pipe. When the breaking cone head moves upward to open the opening at the lower end of the introduction pipe, the water storage tank plays a good buffering role, thereby preventing the soil from being sucked into the introduction pipe and causing blockage when the water pump at the water source stops working due to back suction;

[0031] 3. In the process of the No. 1 adjusting component moving upward, the gas in the connecting rod is compressed by the installation pin, so that the air in the connecting rod enters the shell, so that the nozzle drives the nozzle to protrude from the shell, and the aqueous solution in the arc guide pipe enters the nozzle through the joint and the interface and is sprayed out through the nozzle to clean the dust on the surface of the paulownia wood, thereby preventing the dust from affecting the photosynthesis of the paulownia wood and promoting the growth of the paulownia wood.

DETAILED DESCRIPTION

[0047] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0048] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Embodiment 1, refer to the attached Figure 1 Fig. 7 is the first embodiment of the present invention, which provides a device for accurately supplying nutrients to Paulownia trees, and has the effect of accurately supplying aqueous solution to Paulownia trees and avoiding waste of water resources. The device comprises two arc-shaped flow guide pipes 3 and a plurality of supply pipes 6 arranged on the lower end surface of the arc-shaped flow guide pipes 3, and also comprises a water inlet pipe 5 arranged on the side wall of the arc-shaped flow guide pipe 3. An introduction pipe 8 is fixedly installed on the lower end surface of the supply pipe 6. The bottom end of the introduction pipe 8 is in an inverted truncated cone shape, and a broken cone head 9 is slidably sleeved at the center. The bottom of the introduction pipe 8 and the broken cone head 9 are combined into a cone shape. When the introduction pipe 8 is inserted into the soil, the broken cone head 9 reduces the resistance between the introduction pipe 8 and the soil, saving the operator's time and physical strength.

[0050] See attached Figure 1 and Figure 2 The two arc-shaped flow guide pipes 3 are fixed together by mounting ears 1 at both ends, and each mounting ear 1 is provided with a mounting hole;

[0051] Among them, each arc-shaped flow guide tube 3 is provided with a boss and a circular groove at both ends, and one arc-shaped flow guide tube 3 is spliced ​​together with another arc-shaped flow guide tube 3 by the boss and the circular groove at the head and tail being matched with each other, and then the mounting ears 1 on the two arc-shaped flow guide tubes 3 are installed together by bolts and nuts, so that the assembly of the device of the present invention can be completed, which is simple and efficient;

[0052] See attached Figure 3 The supply pipe 6 and the arc-shaped flow guide pipe 3 are connected to each other through the transfer pipe 7. The connection between the transfer pipe 7 and the supply pipe 6 is hinged with a sealing plug 13. By setting the transfer pipe 7, the aqueous solution in the arc-shaped flow guide pipe 3 can enter the supply pipe 6. The cross-sectional area of ​​each supply pipe 6 is one third of the cross-sectional area of ​​the arc-shaped flow guide pipe 3. When the water flow enters the transfer pipe 7, the speed is accelerated, the kinetic energy is increased, and the sealing plug 13 is impacted and opened;

[0053] In addition, by providing the transfer tube 7, a rectangular shape is formed between the transfer tube 7, the supply tube 6 and the arc-shaped flow guide tube 3, thereby increasing the connection strength and stability between the arc-shaped flow guide tube 3 and the supply tube 6;

[0054] See attached Figure 4a A No. 1 adjustment component 11 is arranged on the side of the sealing plug 13 away from the transfer tube 7, a ventilation component 10 is arranged on the top of the No. 1 adjustment component 11, and the lower end of the No. 1 adjustment component 11 is arranged on the upper end surface of the breaking cone head 9. The No. 1 adjustment component 11 is arranged between the ventilation component 10 and the breaking cone head 9 and has a switch function of connecting the upper and lower parts;

[0055] See attached Figure 6 The first adjustment component 11 includes a connecting rod 1101 and an adjustment plate 1107. A sliding opening 1106 is provided at the center of the adjustment plate 1107. The connecting rod 1101 is vertically slidably connected in the sliding opening 1106. A lifting block 1105 is fixedly installed on the left side wall of the connecting rod 1101. The lifting block 1105 is a right-angled triangle block, and the right-angled side wall on one side is fixedly attached to the side wall of the connecting rod 1101, and the right-angled side wall on the other side is located at the top;

[0056] A limit plate 1104 is fixedly installed on the side wall of the connecting rod 1101, and the top of the limit plate 1104 abuts against the adjusting plate 1107. The lower end of the connecting rod 1101 is fixedly installed on the upper end surface of the breaking cone head 9. When the introduction pipe 8 is inserted into the soil, the adjusting plate 1107 has a limiting effect on the connecting rod 1101 through the limit plate 1104 to prevent the connecting rod 1101 from moving up and down.

[0057] A connecting block 1108 is fixedly mounted on one end of the adjusting plate 1107, and the connecting block 1108 is rotatably mounted on the side wall of the sealing plug 13. A rectangular groove 12 matching the thickness of the connecting block 1108 is provided on the side wall of the sealing plug 13, and the connecting block 1108 is slidably mounted on the inner wall of the rectangular groove 12. A pin sleeve 1109 is fixedly mounted on the other end of the adjusting plate 1107, and a mounting pin 1103 is slidably sleeved on the other end of the pin sleeve 1109. The other end of the mounting pin 1103 is fixedly connected to the inner wall of the supply pipe 6, and a spring 1102 is sleeved on the mounting pin 1103.

[0058] See attached Figure 4b , wherein, when the sealing plug 13 is flushed open under the action of water pressure, the sealing plug 13 deflects to the upper right, pushing the connecting block 1108 to move horizontally to the right, the connecting block 1108 pushes the adjusting plate 1107 to move to the right, and the adjusting plate 1107 pushes the pin sleeve 1109 to compress the spring 1102 along the mounting pin 1103;

[0059] In particular, when the sliding opening 1106 moves to the right, it will gradually approach the lifting block 1105 until it contacts the lifting block 1105. At this time, when the adjusting plate 1107 continues to move to the right, the lifting block 1105 will move upward, driving the connecting rod 1101 and the limiting plate 1104 to move upward through the sliding opening 1106. Finally, the upper end of the connecting rod 1101 pushes the mounting pin 1103 to compress the gas in the connecting rod 1101 upward, so that the gas enters the housing 201 through the second vent 1002 and the first vent 203. The lower end of the connecting rod 1101 drives the broken cone head 9 upward, so that the pouring port below the introduction pipe 8 is opened.

[0060] See attached Figure 5 The breaking cone head 9 can prevent the pouring port at the lower end of the introduction pipe 8 from being blocked, and can be automatically opened when in use and automatically closed when idle;

[0061] See attached Figure 7a and Figure 7b A cleaning assembly 2 is fixedly mounted on the side wall of the supply pipe 6. The cleaning assembly 2 includes a shell 201 and a nozzle 204. A joint 202 is fixedly connected to the upper end surface of the shell 201. The joint 202 is connected to the arc-shaped guide pipe 3 through an auxiliary pipe 4. The nozzle 204 is slidably connected in the shell 201. An interface 206 matching the joint 202 is provided at the top of the nozzle 204. The joint 202 and the interface 206 are staggered. A nozzle 205 is provided at the front end of the nozzle 204. The shell 201 is fixedly connected to the upper end surface of the shell 201. The joint 202 and the interface 206 are staggered. 1 is provided with a No. 1 vent hole 203, the ventilation assembly 10 comprises a ventilation box 1001 and a piston 1003, the ventilation box 1001 is fixedly mounted on the inner wall of the supply pipe 6, the piston 1003 is vertically slidably connected in the ventilation box 1001, the piston 1003 is fixedly mounted on the upper end of the connecting rod 1101, and a No. 2 vent hole 1002 is provided on the inner wall of the ventilation box 1001, the No. 2 vent hole 1002 penetrates the side wall of the supply pipe 6 and corresponds to the No. 1 vent hole 203;

[0062] When the No. 1 regulating component 11 pushes the piston 1003 to move upward, the air in the ventilation box 1001 is squeezed, so that the internal air flows into the shell 201 through the No. 2 vent 1002 and the No. 1 vent 203, so that the air pressure in the shell 201 increases, pushing the nozzle 204 to move forward until the front nozzle 205 of the nozzle 204 completely protrudes from the shell 201, and the nozzle 204 stops moving. At this time, the interface 206 on the nozzle 204 corresponds to the joint 202, and the aqueous solution in the arc-shaped guide tube 3 enters the nozzle 204 through the auxiliary tube 4 through the joint 202 and the interface 206, and finally sprays out from the nozzle 205, spraying water on the paulownia trees surrounded by the arc-shaped guide tube 3, washing away the dust attached to the surface, ensuring the normal photosynthesis, and facilitating the growth of paulownia;

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

[0064] In the basic logic and concept expressed above, the Paulownia forest nutrient precision supply device provided by the present invention is significantly different from the existing one, as shown in the following aspects:

[0065] First, the existing device uses a spray hole arranged in a circle on the lower end surface of the arc-shaped guide pipe 3 to lead the aqueous solution to the ground, or a spray structure is set on the inner side of the arc-shaped guide pipe 3, relying on the penetration of the aqueous solution itself to achieve watering of the trees. The arc-shaped guide pipe 3, the supply pipe 6 and the introduction pipe 8 provided by the present invention are matched. After the introduction pipe 8 is inserted into the soil, the water source is led to the ground for irrigation, thereby avoiding evaporation on the ground and saving water resources. At the same time, after the introduction pipe 8 is inserted into the soil, it is closer to the roots of the paulownia trees, which is conducive to the trees to absorb nutrients from the aqueous solution faster, especially for the early paulownia seedlings, accelerating their growth rate;

[0066] Secondly, the supply pipe 6, the transfer pipe 7 and the introduction pipe 8 provided in the present invention not only have the function of conveying the solution, but also play a supporting role for the arc-shaped flow guiding pipe 3, which is equivalent to a support frame. The transfer pipe 7 is L-shaped and forms a rectangular parallelepiped with the arc-shaped flow guiding pipe 3 and the supply pipe 6 at both ends, which enhances the firmness and stability of the connection between the arc-shaped flow guiding pipe 3 and the supply pipe 6;

[0067] Thirdly, the present invention sets a No. 1 regulating component 11. When watering is needed, the No. 1 regulating component 11 moves up to open the breaking cone head 9 below. When watering is not needed, the No. 1 regulating component 11 moves down to automatically close the breaking cone head 9, thereby preventing large particles from the outside from entering the supply pipe 6 through the introduction pipe 8. After the breaking cone head 9 is inserted into the soil, a water storage tank will be left below the introduction pipe 8. When the breaking cone head 9 moves upward to open the opening at the lower end of the introduction pipe 8, the water storage tank plays a good buffering role, thereby preventing the soil from being sucked into the introduction pipe 8 and causing blockage when the water pump at the water source stops working due to back suction;

[0068] Fourthly, when the No. 1 regulating assembly 11 moves upward, 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 housing 201, so that the nozzle 204 drives the nozzle 205 to protrude from the housing 201, and the aqueous solution in the arc-shaped flow guide tube 3 enters the nozzle 204 through the joint 202 and the interface 206 and then is sprayed out through the nozzle 205, so as to clean the dust on the surface of the paulownia wood, thereby preventing the dust from affecting the photosynthesis of the paulownia wood and promoting the growth of the paulownia wood;

[0069] In summary, the present invention adopts a nutrition supply method that is completely different from the existing one. The device effectively solves the problem of resource waste and inability to achieve accurate supply during the use of the supply device in the prior art by utilizing the advantages of easy manufacturing and low cost of the No. 1 adjustment component 11 and the breaking cone head 9.

[0070] Specifically, the operating method of the device for accurately supplying nutrients to paulownia trees in the present invention comprises the following steps:

[0071] S1: Assemble the supply device, fit the boss at the end of the arc-shaped flow guide pipe 3 into 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 by bolts, so that the arc-shaped flow guide pipes 3 surround the periphery of the paulownia forest;

[0072] S2: Install the supply device, press the arc-shaped guide tube 3 by hand or by a pressing tool, so that the introduction tube 8 at the lower end of the arc-shaped guide tube 3 is inserted into the soil around the paulownia wood;

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

[0074] The impact force generated by the kinetic energy of the water flow opens the sealing plug 13, so that the No. 1 regulating component 11 rises, and the top of the No. 1 regulating component 11 squeezes the piston 1003 to squeeze the air in the ventilation box 1001 into the shell 201, so that the nozzle 205 at the front end of the nozzle 204 protrudes from the shell 201, and the interface 206 at the upper end of the nozzle 204 corresponds to the joint 202. A part of the aqueous solution in the arc-shaped guide pipe 3 enters the nozzle 204 through the auxiliary pipe 4 and is sprayed out to clean the dust on the surface of the paulownia wood;

[0075] At the same time, the first regulating component 11 lifts the lower breaking cone head 9 upwards, preventing the breaking cone head 9 from opening the lower end of the introduction pipe 8, and the water flows out through the lower end opening of the introduction pipe 8 to accurately irrigate the Paulownia trees;

[0076] S4: Turn off the supply device and the water pump at the water source. At this time, the sealing plug 13 deflects downward under the action of gravity and blocks the port of the transfer tube 7 again. The No. 1 adjustment component 11 also moves downward under the action of gravity, and the piston 1003 slides downward. The gas in the shell 201 returns to the ventilation box 1001 again, and the nozzle 204 retracts into the shell 201 with the nozzle 205. The broken cone head 9 at the bottom of the No. 1 adjustment component 11 also blocks the lower port of the inlet pipe 8 again.

[0077] Embodiment 2, refer to the attached Figure 8 , Fig. 9 , Fig.10, Fig.11a and Fig.11b , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a second regulating assembly 17, a power assembly 16 and a rotating cone head 15, which can realize watering the trees while loosening the soil around the paulownia trees. The first regulating assembly 11, the second regulating assembly 17, the power assembly 16 and the rotating cone head 15 have the advantages of simple manufacturing process, very low use cost and stable and reliable performance, and are used to replace traditional manual or loosening equipment for loosening the soil.

[0078] See attached Fig.11a and Fig.11b The first adjustment component 11 is an adjustment rod, and the lower end surface of the first adjustment component 11 is fixedly installed with the second adjustment component 17, and the second adjustment component 17 includes a containing box, and a plurality of fine holes 1706 are opened on the side wall of the second containing box, and the containing box is fixedly installed on the lower end surface of the first adjustment component 11, and a water-absorbing expansion strip 1701, an extrusion sheet 1702 and a connecting column 1703 are arranged in the containing box, and the extrusion sheet 1702 is slidably connected in the containing box, and the water-absorbing expansion strip 1701 is fixedly adhered to the extrusion sheet 1702, and the connecting column 1703 is fixedly installed at the lower end of the extrusion sheet 1702, and a limiting sheet 1705 is also fixedly sleeved on the connecting column 1703, and the lower end of the connecting column 1703 passes through the lower side wall of the containing box and is provided with a power component 16 through a transfer sleeve 1704;

[0079] See attached Fig.10 , Fig.11a and Fig.11b The power assembly 16 includes a rotating shaft 1601 and an impeller 1602. The impeller 1602 is fixedly sleeved on the rotating shaft 1601. The upper end of the rotating shaft 1601 is rotatably mounted in the adapter sleeve 1704. The lower end of the rotating shaft 1601 is fixedly mounted with a rotating cone head 15. The rotating cone head 15 is rotatably mounted at the bottom of the introduction pipe 8. A plurality of circular holes 14 are opened on the side wall of the rotating cone head 15 at equal intervals.

[0080] Reference Fig.11a , which more significantly shows the state of the water-absorbing and swelling strip 1701 in this embodiment when no water source is introduced;

[0081] Reference Fig.11b, which more significantly shows the state of the water-absorbing expansion strip 1701 when the water source is introduced into the embodiment. At this time, the water source enters the introduction pipe 8 through the water pump, the arc-shaped guide pipe 3, the transfer pipe 7 and the supply pipe 6. After the water flows through the fine hole 1706 and enters the second regulating component 17, the water-absorbing expansion strip 1701 absorbs water and expands (the expansion volume is about 90% of the original volume), thereby pushing the first regulating component 11 to move upward, compressing the air in the connecting rod 1101, so that the air pressure of the shell 201 increases, and the nozzle 204 drives the nozzle 205 to protrude from the shell 201 to clean the surface of the paulownia wood. The effect of the cleaning component 2 here is the same as that of the embodiment 1;

[0082] At the same time, water flows downward through the inlet pipe 8, driving the impeller 1602 to rotate, and then driving the rotating shaft 1601 to rotate. The rotating shaft 1601 drives the rotating cone head 15 to rotate to loosen the surrounding soil. Finally, the water flows into the soil through the circular holes 14 on the periphery of the rotating cone head 15. After the irrigation is completed, the water absorbed by the water-absorbing expansion strip 1701 is slowly discharged, and the water-absorbing expansion strip 1701 contracts, causing the piston 1003 to move downward, so that the pressure of the shell 201 increases, and the gas in the shell 201 returns to the ventilation box 1001 through the No. 1 vent 203 and the No. 2 vent 1002. The nozzle 204 brings the nozzle 205 into the shell 201 for reset. The water absorbed by the water-absorbing expansion strip 1701 flows out through the pores 1706 and is finally discharged through the circular hole 14, cleaning and dredging the circular hole 14 to prevent the circular hole 14 from sucking in soil due to the back suction phenomenon when the water pump stops working, and blocking the circular hole 14 after drying;

[0083] The Paulownia tree nutrient precision supply device provided in this embodiment is significantly different from the existing one, as shown in the following aspects:

[0084] First, the water-absorbing expansion strip 1701 absorbs water and expands (expands by about 90%), thereby pushing the first regulating component 11 upward, compressing the air in the connecting rod 1101, increasing the air pressure in the shell 201, and the nozzle 204 drives the nozzle 205 to protrude from the shell 201, cleaning the surface of the paulownia forest, promoting its photosynthesis, and facilitating the growth of the paulownia 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 washing the dust and falling on the ground, thereby reducing the evaporation waste of the water solution;

[0086] Third, after the irrigation is completed, the water absorbed by the water-absorbing expansion strip 1701 is slowly discharged, the water-absorbing expansion strip 1701 shrinks, and the discharged water flows out through the fine hole 1706 and finally discharged through the circular hole 14, so as to clean and dredge the circular hole 14, and avoid the circular hole 14 from sucking in soil due to the back suction phenomenon when the water pump stops working, and the circular hole 14 is blocked by the soil after drying;

[0087] In summary, the device utilizes the kinetic energy of the water flow to drive the power assembly 16 to rotate, and then drives the rotating cone head 15 to rotate, thereby loosening the soil around the paulownia tree, which is beneficial to the penetration of the aqueous solution in the soil and promotes the growth of the paulownia trees.
