[0002] Due to the unique climate resources in the mountainous area, it is the main production area of ​​specialty tea cash crops. The mountainous area has abundant precipitation, but it is very unevenly distributed in time and space, and water and drought disasters are relatively frequent. It is mainly hilly area, and hills account for about 75%-80% of the total area. The hilly area has steep terrain and scattered tea gardens. Although the annual precipitation generally meets the water required for the growth of tea trees, the coupling between the monthly precipitation and the water demand of tea trees is poor. "Summer drought" and "autumn drought" often occur during the production season, affecting the yield, quality and benefits of tea.

[0003] During the dry season, the soil has difficulty retaining water and irrigation is also difficult, causing significant economic losses to tea farmers.

[0004] A large number of tea gardens in mountainous areas are located on mountain slopes, and it is difficult to implement traditional ground irrigation methods. Due to the lack of good irrigation and cooling conditions in summer and autumn, the taste of summer and autumn tea is bitter, forcing some tea companies and tea farmers to abandon the picking and production of summer and autumn tea, resulting in low annual yields of tea gardens (farms), serious waste of resources, and reduced economic benefits. Therefore, it is urgent to develop a water-lifting irrigation and fertilization device suitable for tea gardens on hilly slopes. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0042] Please refer to Figure 1 In an embodiment of the present invention, a water-lifting irrigation and fertilization device for a tea garden on a hilly slope is provided, comprising a water-lifting component and a drip irrigation component. The water-lifting component is connected to a high-level water tank 10, and the water-lifting component is used to send clean water in a power water tank 1 located at a low position to the high-level water tank 10 located at a high position; the drip irrigation component is connected to the high-level water tank 10, and a Venturi fertilizer applicator 15 is connected between the drip irrigation component and the high-level water tank 10. In the process of the high-level water tank 10 sending clean water to the drip irrigation component, liquid fertilizer is added to the transported water flow through the Venturi fertilizer applicator 15, and the liquid fertilizer enters the drip irrigation component and is applied to the tea garden 12, so that the tea plants in the tea garden 12 can absorb the fertilizer.

[0043] Please refer to Figure 1 and Figure 3In a preferred embodiment of the present invention, the water lifting assembly includes a power water pool 1, which is arranged at a low position on a hill slope. The power water pool 1 is connected to a water source stream 2. In actual use, the water from the water source stream 2 entering the power water pool 1 needs to be filtered. Generally, a grid, a filter screen and other structures are used to ensure that there are no debris in the water entering the power water pool 1, so as to avoid damage to the irrigation and fertilization device during the water lifting process;

[0044] Furthermore, the power water pool 1 is connected to the water hammer pump through a power water pipe 3, the top of the power water pipe 3 is connected to the bottom water outlet of the power water pool 1, and the power water pipe 3 is used to discharge the water in the power water pool 1 so that the water enters the water hammer pump; preferably, the power water pipe 3 is installed straight and no bending is allowed, and the angle between the power water pipe 3 and the horizontal line is about 7 degrees;

[0045] The water hammer pump comprises a curved pipe body 8, the curved portion of the curved pipe body 8 is upward, a drain valve 4 is arranged at the top of the curved portion of the curved pipe body 8, and a diffusion pipe 5 is arranged at the water outlet of the drain valve 4; the transverse portion of the curved pipe body 8 is connected to the bottom end of the power water pipe 3, and a valve is arranged at the connection between the curved pipe body 8 and the power water pipe 3, which is used to control the on and off of the power water pipe 3 to deliver water to the water hammer pump;

[0046] Furthermore, an air tank 7 is provided at the top of the outlet pipe of the transverse portion of the elbow body 8, and a water delivery valve 6 is provided on the outlet pipe; a water pumping pipe 9 is connected to one side of the air tank 7, and the other end of the water pumping pipe 9 is connected to a high-level water tank 10;

[0047] The water lifting assembly provided in the embodiment of the present invention delivers water in the power water pool 1 at a low position to the high-position water pool 10 at a high position through the arrangement of the power water pipe 3, the drain valve 4, the diffuser 5, the water transfer valve 6, the air tank 7, the curved pipe body 8 and the water lifting pipe 9.

[0048] The implementation process of the water extraction assembly provided by the present invention is as follows:

[0049] First, water from the water source stream 2 is introduced into the power water pool 1 through the water diversion facilities, and the power water pipe 3 with a certain drop is provided to input the water into the water hammer pump. The drop of the power water pipe 3 is the energy source for the water hammer pump to work; then part of the water is transported to the high-level water pool 10 through the water hammer pump, and the remaining tail water is discharged back into the power water pool 1 through the overflow pipe;

[0050] Secondly, during the implementation of the water hammer pump, the water hammer pump is connected to the power water pipe 3, and the length of the power water pipe 3 should be 6 to 8 times the height difference. For example, when the height difference is 4 meters, the length of the power water pipe 3 should be 24 to 32 meters. The higher the head, the greater the multiple should be. The material of the power water pipe 3 should be selected according to the specific mountain environment. The pressure-resistant seamless steel pipe should be hard enough and not deformed under the huge water hammer pressure, so that the power is sufficient and the operation efficiency of the water hammer pump is higher.

[0051] The special feature of the water hammer pump of the present invention is that the diffuser 5 is arranged behind the bend of the elbow main body 8, so that the flow channel of the drain valve 4 is enlarged at the elbow. When the cross-section of the pipeline is suddenly expanded, the flow beam at the interface is dispersed and swirled into a strong vortex, resulting in impact loss. Therefore, in order to reduce the impact loss and obtain better hydraulic performance, the pump body section of the drain valve 4 is equipped with a diffuser 5, and there is no gap between the elbow, the diffuser 5 and the drain valve 4. The vortices generated by the flow will interfere with each other, reducing the head loss.

[0052] For further information, please refer to Figure 1 and Figure 3 In the embodiment of the present invention, a second infusion pipe 17 is connected to the bottom water outlet of the high-level water tank 10, and the other end of the second infusion pipe 17 is connected to the first infusion pipe 16; a venturi fertilizer applicator 15 is provided at the connection between the second infusion pipe 17 and the first infusion pipe 16, and the venturi fertilizer applicator 15 is used to absorb liquid fertilizer in the fertilizer barrel 11;

[0053] Among them, Figure 2 As shown, the venturi fertilizer applicator 15 includes a connecting pipe 151, which is arranged in parallel with the first infusion pipe 16, wherein the connecting pipe 151 is provided with a first venturi tube 152 and a second venturi tube 154 which are arranged opposite to each other in series, wherein the first venturi tube 152 and the second venturi tube 154 are connected by a throat pipe 153, and a suction pipe 155 is connected to the throat pipe 153, and the bottom end of the suction pipe 155 extends into the fertilizer barrel 11, when water flows through the connecting pipe 151, due to the first The design of the venturi tube 152 and the second venturi tube 154 (the water flows through a cross-section that gradually decreases and then gradually increases). When the water flows through the throat tube 153 in the narrow part, the flow rate will increase, and the pressure will decrease. This change in flow rate and reduction in pressure will form a pressure difference. By utilizing this pressure difference, the fertilizer solution can be evenly sucked out from the open fertilizer barrel 11 and mixed with the water flow to achieve water-fertilizer mixing. After the mixed water-fertilizer solution enters the first infusion pipe 16, it is fertilized into the tea garden 12 through the drip irrigation assembly.

[0054] Please continue to refer to Figure 3-Figure 7In the embodiment of the present invention, the drip irrigation assembly includes a plurality of drip irrigation bodies 14 connected to the first infusion pipe 16, and a drip irrigation belt 13 is detachably installed on each drip irrigation body 14, so that the drip irrigation belt 13 is easy to replace, and the drip irrigation belt 13 is installed and laid in the tea garden 12;

[0055] Among them, Figure 4-Figure 6 In the embodiment of the present invention, an impeller mechanism is further included, the impeller mechanism includes an impeller tank 161, the drip irrigation body 14 includes a support box 141, the support box 141 is fixedly mounted on the impeller tank 161, the impeller tank 161 is serially connected to the first infusion pipe 16, an impeller shaft 146 is rotatably arranged in the impeller tank 161, an impeller assembly 147 is arranged on the impeller shaft 146, when the fertilizer solution flowing through the first infusion pipe 16 passes through the impeller tank 161, it impacts the impeller assembly 147, and drives the impeller shaft 146 to rotate;

[0056] Furthermore, one end of the impeller shaft 146 is connected to the output shaft of the servo motor 143 through an electromagnetic clutch 145. By controlling the opening of the electromagnetic clutch 145, the impeller shaft 146 can be driven to rotate when the servo motor 143 is started. Correspondingly, when the electromagnetic clutch 145 is closed, the free rotation of the impeller shaft 146 is not affected. The servo motor 143 is supported and fixedly installed on the motor frame 142, and the motor frame 142 is fixedly arranged on the support box 141. The other end of the impeller shaft 146 is coaxially fixedly installed with a first gear 148.

[0057] Furthermore, the support box 141 is provided with a first chamber 1411 and a third chamber 1413;

[0058] Among them, a push-pull piston 1495 is sealed and slidably arranged in the first chamber 1411, and a push-pull member for pushing the push-pull piston 1495 to move back and forth is arranged in the third chamber 1413. The push-pull member is transmission connected to the impeller mechanism arranged in series on the first infusion tube. When the push-pull piston reciprocates in the first chamber, the fertilizer solution transported in the first infusion tube is discharged through the drip port; the push-pull member is transmission connected to the first gear 148 of the impeller mechanism; the support box 141 is also provided with a delivery pipe 144 connected to the first chamber 1411, the delivery pipe 144 is connected to the first infusion pipe 16, and a second one-way valve 1441 is arranged at the connection between the delivery pipe 144 and the first chamber 1411. The second one-way valve 1441 is used to allow the fertilizer solution in the delivery pipe 144 to enter the first chamber 1411 in one direction.

[0059] Please continue to refer to Figure 5 and Figure 7In the embodiment of the present invention, a plurality of drip ports 1311 are arranged at equal intervals on the drip irrigation belt 13, and a pressure valve 131 is arranged at the connection between the drip port 1311 and the drip irrigation belt 13. When the pressure in the drip irrigation belt 13 increases, the pressure valve 131 is turned on. At this time, the fertilizer solution in the drip irrigation belt 13 can be discharged through the drip port 1311. After the pressure in the drip irrigation belt 13 is released, the pressure valve 131 is closed, and the cycle is repeated, thereby forming a drip irrigation effect of the fertilizer.

[0060] Furthermore, one end of the drip irrigation belt 13 is connected to a connecting pipe head 132, and an external threaded interface 1321 is provided at the port of the connecting pipe head 132. The external threaded interface 1321 is installed at the open end of the first chamber 1411 by a threaded connection, and a sealing gasket is provided at the connection between the external threaded interface 1321 and the support box 141. A first one-way valve 1322 is installed at the port of the external threaded interface 1321. The first one-way valve 1322 is used to allow the fertilizer solution to enter the connecting pipe head 132 in one direction;

[0061] It should be noted that when the external threaded interface 1321 is removed from the support box 141 , the first one-way valve 1322 is also removed because the first one-way valve 1322 is installed on the external threaded interface 1321 .

[0062] Therefore, combined with the above discussion on the structure, the implementation process of the drip irrigation assembly of the embodiment of the present invention is as follows:

[0063] When the liquid fertilizer solution flows through the first liquid infusion pipe 16 and passes through the impeller tank 161, the solution impacts the impeller assembly 147 to rotate the impeller shaft 146, and the rotating impeller shaft 146 drives the first gear 148 to rotate. Due to the linkage between the first gear 148 and the push-pull member, the push-pull piston 1495 is driven by the push-pull member to reciprocate in the first chamber 1411. Among them, due to the provision of the second one-way valve 1441 and the first one-way valve 1322, when the push-pull piston 1495 moves to the left in the first chamber 1411, the second one-way valve 144 1 is turned on, and the first one-way valve 1322 is closed. At this time, the liquid fertilizer in the first infusion pipe 16 is sucked into the first chamber 1411 by means of the delivery pipe 144; when the push-pull piston 1495 moves to the right in the first chamber 1411, the second one-way valve 1441 is closed, and the first one-way valve 1322 is turned on, so that the fertilizer solution in the first chamber 1411 enters the connecting pipe head 132 and the drip irrigation belt 13. At this time, the pressure in the drip irrigation belt 13 increases, and the fertilizer solution in the drip irrigation belt 13 is discharged through the drip port 1311, forming the effect of fertilizer drip irrigation.

[0064] In addition, the detachable structure between the external threaded interface 1321 and the support box 141 provided in the present invention can replace the drip tape 13; moreover, after the drip tape 13 is removed, the first chamber 1411 is directly connected to the outside, and when the push-pull piston 1495 continues to move in the first chamber 1411, it no longer affects the conduction state of the second one-way valve 1441 (after the drip tape 13 is removed, the second one-way valve 1441 will always be in a non-conducting state).

[0065] Please continue reading Figure 5 and Figure 6 In the embodiment of the present invention, the push-pull member includes a rotating disk 1491, which is rotatably arranged on the third chamber 1413, and a second gear 149 is coaxially installed on the rotating disk 1491, and the second gear 149 is meshed with the first gear 148; the push-pull member also includes a push-pull frame 1493, which is slidably sleeved on the guide column 1492, and the guide column 1492 is fixedly installed on one side of the upper surface of the rotating disk 1491, so that when the rotating disk 1491 rotates, the guide column 1492 performs a circular motion, thereby pushing the push-pull frame 1493 to reciprocate;

[0066] The push-pull frame 1493 and the push-pull piston 1495 are connected via a piston rod 1494;

[0067] Based on the above structure, it can be seen that when the first gear 148 rotates, it drives the second gear 149 and the turntable 1491 to rotate, and then drives the guide column 1492 to make a circular motion, thereby pushing the push-pull frame 1493 and the push-pull piston 1495 to move back and forth, that is, pushing the push-pull piston 1495 to move back and forth in the first chamber 1411, thereby achieving the drip irrigation effect of discharging liquid fertilizer from the drip irrigation belt 13.

[0068] Please continue reading Figure 4 and Figure 5 A second chamber 1412 is also provided in the support box 141, and the second chamber 1412 is communicated with the first chamber 1411, so that the air pressure in the chamber on the left side of the push-pull piston 1495 can be balanced; a controller 18 is also provided on the support box 141, and the controller 18 is arranged above the mesh at the top of the second chamber 1412. When the push-pull piston 1495 moves in the first chamber 1411, the air flow effect of the mesh on the second chamber 1412 can be accelerated to achieve a certain heat dissipation effect on the controller 18.

[0069] Furthermore, the present invention uses a speed sensor to detect the speed of the impeller shaft 146. The speed sensor can be set on the impeller shaft 146 or on the first gear 148. When the speed of the impeller shaft 146 is too fast or too slow, the controller 18 controls the electromagnetic clutch 145 to open, so that the output shaft of the servo motor 143 and the impeller shaft 146 are linked, and the output shaft of the servo motor 143 is controlled to rotate at a required speed, and then the servo motor 143 is used to drive the impeller shaft 146 to rotate, so that the impeller shaft 146 can rotate at a required speed, because the speed of the impeller shaft 146 will affect the speed of the push-pull piston 1495 to reciprocate in the first chamber 1411, and further affect the speed of change of the pressure in the drip irrigation belt 13, that is, affect the drip irrigation speed of the liquid fertilizer in the drip irrigation belt 13;

[0070] The specific control principle is as follows: the controller 18 receives the speed signal of the impeller shaft 146, compares the real-time speed of the impeller shaft 146 with the preset speed built into the controller 18, and based on the comparison result, the controller 18 generates a control instruction to control the working state of the servo motor 143 and the electromagnetic clutch 145 so that the speed of the impeller shaft 146 can meet the requirements.
