Description

Technical Field

[0001] The invention relates to the technical field of agricultural fertilization, and in particular to a rice field biogas slurry fertilization system and a fertilization method. Background Art

[0002] With the development of agricultural modernization, how to efficiently utilize resources and increase crop yields has become a key issue in agricultural production; as an organic fertilizer, biogas slurry is rich in nutrients such as nitrogen, phosphorus, and potassium, and plays an important role in promoting crop growth; in the process of rice field cultivation, the rational application of biogas slurry can improve soil structure, increase soil fertility, and improve rice yield and quality.

[0003] At present, most rice fields use traditional farmland irrigation methods to apply biogas slurry fertilization. Under the traditional irrigation mode, the biogas slurry flows directly into the rice fields through pipes or ditches, which can easily cause the biogas slurry concentration in some local areas to be too high or too low and cannot be evenly distributed in the entire rice field area. This not only affects the balanced absorption of nutrients by rice seedlings, but may also cause rice seedlings in some areas to grow too tall due to excess nutrients, or grow slowly due to insufficient nutrients. Moreover, since the biogas slurry mainly stays in the surface layer, it is difficult to penetrate into the soil layer where the roots of the rice fields are located, resulting in the inability of the roots of the rice seedlings to effectively absorb nutrients, reducing the effectiveness of the biogas slurry as a fertilizer. Summary of the invention

[0004] In view of this, the present invention provides a rice field biogas slurry fertilization system and fertilization method, which can solve the shortcomings of using traditional farmland irrigation methods to carry out biogas slurry fertilization, that is, the biogas slurry cannot be evenly distributed in the entire rice field area, and the biogas slurry mainly stays in the surface layer and is difficult to penetrate into the soil layer where the rice field roots are located.

[0035] See also Figure 8 and Fig. 9 As shown, the reset mechanism includes an annular frame 1601 and a spring 1603; an annular frame 1601 is slidably arranged on the inner side of the insertion tube 13, and the annular frame 1601 is connected to the left end of the movable rod 15, and water holes 1602 are spaced apart on the annular frame 1601; a spring 1603 is connected between the right side of the annular frame 1601 and the left side of the annular column 14, and the spring 1603 is made of corrosion-resistant material, and the surface of the spring 1603 is coated with an anti-corrosion coating to extend the service life of the spring 1603.

[0036] When in use, biogas slurry is input into the liquid storage tank 1 through the biogas slurry providing place 101 for storage, so that an appropriate amount of biogas slurry is stored in the liquid storage tank 1, and then the longer (length) and shorter (width) sides of the rice field 102 are found, and the butt joint pipe 4 is placed near the shorter side of the rice field 102 (such as Figure 2As shown in the figure, the joint 5 on the butt-joint pipe 4 cannot be aligned with the rice seedling 103, and the joint 5 on the butt-joint pipe 4 needs to be staggered with the rice seedling 103 so as to lay the distribution pipe 7 later), and then the first connecting plate 602 is twisted to rotate, so that the first connecting plate 602 drives the first fixing rod 601 to rotate, so that the first fixing rod 601 drills into the soil through rotation, and then the first fixing rod 601 fixes the butt-joint pipe 4 and the joint 5, and then when the first connecting plate 602 approaches the limit block 603 and the first connecting plate 602 When the slot of the first connecting plate 601 is aligned with the limit block 603, the first connecting plate 602 is pressed down to make the limit block 603 snap into the slot on the first connecting plate 602, so as to limit the first connecting plate 602, and then repeat the above operation, drill all the first fixing rods 601 into the soil, and make all the limit blocks 603 snap into the corresponding slots on the first connecting plate 602; then adjust the length of the distribution pipe 7 according to the longer side of the rice field 102 (make sure it is slightly longer than the long side of the rice field 102, so as to better cover the entire area domain), and then, the distribution pipes 7 are laid at intervals in the rice field 102 so as to be connected to the joints 5 one by one. When the distribution pipes 7 are correctly placed, the mounting frame 10 will be stably supported on the surface of the rice field 102, and at the same time, the end of the insertion pipe 13 will naturally sag due to gravity and contact the ground, ensuring that the cone of the movable rod 15 can be smoothly inserted into the soil. After all the distribution pipes 7 are laid, hold the sleeve 801 and move it to the right, so that the sleeve 801 drives the rubber tube 802 and the right end of the distribution pipe 7 to move to the right. When the distribution pipe 7 is When the right end contacts the joint 5, the joint 5 will stretch the right end of the distribution pipe 7, so that the right end of the distribution pipe 7 squeezes the rubber tube 802, and then as the right end of the distribution pipe 7 continues to move to the right, the right end of the distribution pipe 7 will be sleeved on the joint 5 to complete the docking. During this period, due to the elasticity of the rubber tube 802, the rubber tube 802 will apply pressure to the right end of the distribution pipe 7, thereby pressing the right end of the distribution pipe 7 against the joint 5, thereby stabilizing the right end of the distribution pipe 7 to prevent the right end of the distribution pipe 7 from falling off the joint 5;Then, hold the second connecting plate 904 and rotate it at the left end of the distribution pipe 7, so as to drive the second fixing rod 901 to rotate, so that the second fixing rod 901 drills into the soil by rotation, thereby fixing the second fixing rod 901. After the second fixing rod 901 is fixed, the left end of the distribution pipe 7 is placed between the clamping rod 905 and the groove 903, and then the connecting block 902 is pulled upward with force to make the connecting block 902 drive the left end of the distribution pipe 7 upward. When the left end of the distribution pipe 7 contacts the clamping rod 905, the clamping rod 905 will press the left end of the distribution pipe 7 The left end of the distribution pipe 7 is flattened to close the left end of the distribution pipe 7, and then the clamping rod 905 presses the flattened left end of the distribution pipe 7 into the groove 903 of the connecting block 902, so that the clamping rod 905 limits the flattened left end of the distribution pipe 7 in the groove 903, thereby preventing the left end of the distribution pipe 7 from leaking (the leakage prevention treatment of the left end of the distribution pipe 7 in this way is lower in cost and more convenient to operate than the traditional detachable end joint); then, one end of the connecting pipe 3 is docked with the water outlet of the water pump 2, and the other end of the connecting pipe 3 is docked with the docking pipe 4 (such as; Figure 2 As shown), the right end of the distribution pipe 7 is manually pulled to the right (the length of the distribution pipe 7 is slightly larger than the longer side of the rice field 102, so pulling the right end of the distribution pipe 7 to the right will not affect the fixed position of the left end of the distribution pipe 7). As the distribution pipe 7 drives the mounting frame 10 and the rotating frame 12 to move to the right, since the rotating frame 12 is rotatably set on the mounting frame 10, the insertion pipe 13 is rotatably set on the rotating frame 12, and the end of the insertion pipe 13 naturally droops due to gravity and contacts the ground, the insertion pipe 13 is inserted into the mounting frame 10. The tube 13 forms an inclination angle with the soil surface. The rightward movement of the rotating frame 12 can exert a combined force on the insertion tube 13 along the inclination angle, so that the insertion tube 13 can drive the cone of the movable rod 15 to move downward and insert into the soil. Then, as the mounting frame 10 and the rotating frame 12 continue to move to the right, the cone of the movable rod 15 can be inserted deeper and deeper, so that the movable rod 15 drives part of the insertion tube 13 to be inserted into the soil. After the insertion of part of the insertion tube 13 is completed, the right end of the distribution tube 7 is loosened. In this way, the installation of the fertilization system can be completed.

[0037] When it is necessary to fertilize the rice seedlings 103 in the rice field 102, it is only necessary to start the water pump 2 so that the water pump 2 can pump the biogas liquid in the liquid storage tank 1 into the connecting pipe 3, the butt pipe 4, the joint 5, the distribution pipe 7 and the insertion pipe 13. As the biogas liquid flowing into the insertion pipe 13 increases, when the pressure applied by the biogas liquid to the movable rod 15 is greater than the elastic force of the spring 1603, the biogas liquid in the insertion pipe 13 will squeeze the annular frame 1601 and the movable rod 15 to move downward, and the spring 1603 is compressed, so that the gap between the movable rod 15 and the annular column 14 gradually increases, so that the biogas liquid in the insertion pipe 13 flows into the gap between the movable rod 15 and the annular column 14 through the water hole 1602, thereby making the biogas liquid The biogas flows out through the gap into the soil of the rice field 102, thereby fertilizing the rice seedlings 103 in the rice field 102, and by discharging the biogas liquid in the soil, it can be easily absorbed by the roots of the rice seedlings 103. After the fertilization is completed, the water pump 2 is turned off. As the biogas liquid flowing into the insertion tube 13 decreases, when the pressure applied by the biogas liquid to the movable rod 15 is less than the elastic force of the spring 1603, the spring 1603 returns to its original state, and the spring 1603 drives the annular frame 1601 and the movable rod 15 to move upward and reset, so that the gap between the movable rod 15 and the annular column 14 is gradually reduced, thereby stopping the biogas liquid in the insertion tube 13 from flowing out and blocking the soil in the rice field 102 from entering the insertion tube 13.

[0038] Later, as the rice seedlings 103 grow, the roots of the rice seedlings 103 will penetrate deep into the soil. At this time, the right end of the distribution pipe 7 can be manually pulled to the right regularly to make the cone of the movable rod 15 and part of the insertion pipe 13 inserted deeper and deeper, so that the biogas slurry applied in the rice field 102 will also penetrate deep into the soil, so that the roots of the rice seedlings 103 can absorb the fertilizer in the soil.

[0039] When not in use, disconnect the two ends of the connecting pipe 3 from the water outlet of the water pump 2 and the docking pipe 4 respectively, then press the connecting block 902 downward with force to make the clamping rod 905 leave the groove 903, then take the left end of the distribution pipe 7 out from between the clamping rod 905 and the groove 903, and then twist the second connecting plate 904 in reverse to drive the second fixing rod 901 to twist out of the soil, then hold the sleeve 801 and move it to the left, so that the sleeve 801 drives the rubber tube 802 and the right end of the distribution pipe 7 to move to the left and reset, when the right end of the distribution pipe 7 is separated from the joint 5, the rubber tube 802 returns to its original state, and the rubber tube 802 drives the right end of the distribution pipe 7 to shrink, and then as the right end of the distribution pipe 7 continues to move to the left, the right end of the distribution pipe 7 will leave the joint 5, and then the distribution pipe 7 is pulled upward to be taken out, so that the cone of the movable rod 15 and part of the insertion tube 13 are separated from the soil, and then the first connecting plate 602 is pulled upward to move upward, so that the limit block 603 is separated from the slot of the first connecting plate 602, and then the first connecting plate 602 is twisted to reverse, thereby driving the first fixed rod 601 to twist out of the soil, and finally the docking pipe 4 is removed from the rice field 102. In this way, the disassembly of the fertilization system can be completed.

[0040] See also Figure 8 and Fig.10 As shown, a blocking mechanism is also included, which includes a fixing ring 17, a rubber plate 18 and a baffle 19; a fixing ring 17 is arranged on the inner side of the insertion tube 13, and the fixing ring 17 is located on the left side of the annular frame 1601; a rubber plate 18 is connected to the upper right side of the fixing ring 17, and a baffle 19 is connected to the rubber plate 18, and the baffle 19 blocks the middle part of the fixing ring 17.

[0041] By setting a blocking mechanism, when the biogas slurry flows into the insertion tube 13, as the biogas slurry in the insertion tube 13 increases, when the pressure exerted by the biogas slurry on the baffle 19 is greater than the elastic force of the rubber sheet 18, the biogas slurry will squeeze the baffle 19 to open, causing the rubber sheet 18 to deform. After the baffle 19 is opened, the biogas slurry will flow through the middle of the fixing ring 17. After the water pump 2 is turned off, as the biogas slurry flowing into the insertion tube 13 decreases, when the pressure exerted by the biogas slurry on the baffle 19 is less than the elastic force of the rubber sheet 18, the rubber sheet 18 returns to its original state, and the rubber sheet 18 drives the baffle 19 to close, so that the baffle 19 is fixed to the ring 17 again. 7, thereby separating the space below the baffle plate 19 in the insertion tube 13 into a closed space. Later, when the spring 1603 drives the annular frame 1601 and the movable rod 15 to move upward and reset, since the space below the baffle plate 19 in the insertion tube 13 is a closed space, when the movable rod 15 moves upward, the gas or liquid in the closed space will be pressurized to flow out from the gap between the movable rod 15 and the annular column 14. The outflow of gas or liquid in the closed space can flush out some soil that has seeped into the gap, thereby preventing the soil from being stuck in the gap between the movable rod 15 and the annular column 14.

[0042] See also Fig.11 As shown, it also includes a shovel plate 20 and a resistance-increasing plate 21; the shovel plate 20 is connected to the right side of the bottom of the insertion tube 13; the resistance-increasing plate 21 is symmetrically arranged at the front and back of the insertion tube 13, and the shovel plate 20 and the resistance-increasing plate 21 are both used to assist the conical structure of the movable rod 15 to be inserted into the rice field 102.

[0043] When the right end of the distribution pipe 7 is pulled to move right, as the distribution pipe 7 drives the mounting frame 10 and the rotating frame 12 to move right, the mounting frame 10 and the rotating frame 12 can apply a thrust to push the cone of the movable rod 15 into the soil. By setting the shovel plate 20 and the resistance increasing plate 21, when the rotating frame 12 moves to the right, the shovel plate 20 and the resistance increasing plate 21 will be affected by the resistance of the soil, thereby gradually increasing the resistance of the insertion tube 13 to move to the right. When the resistance encountered by the insertion tube 13 is equal to the pulling force of the rotating frame 12 on the insertion tube 13, the insertion tube 13 can stop moving, thereby ensuring the position of the insertion tube 13 and preventing the insertion tube 13 from moving to the right with the rotating frame 12 and causing position deviation.

[0044] See also Fig.12 As shown, a conversion mechanism is also included, which includes a power storage box 22 and a photovoltaic panel 23; a power storage box 22 is arranged at the lower front part of the liquid storage tank 1; a photovoltaic panel 23 for converting solar energy into electrical energy is installed on the top of the power storage box 22, and the photovoltaic panel 23 and the water pump 2 are electrically connected to the power storage box 22.

[0045] By setting up a conversion mechanism, when sunlight shines on the photovoltaic panel 23, the photovoltaic panel 23 will convert the solar energy into electrical energy and store it in the power storage box 22. The electrical energy stored in the power storage box 22 can be used by the water pump 2, thereby saving resources.

[0046] See also Figure 1-Figure 9As shown, the present invention also provides a fertilization method of a rice field biogas slurry fertilization system, comprising the following steps: first, the biogas slurry is input into the liquid storage tank 1 for storage through the biogas slurry providing place 101; then, the butt joint pipe 4 is placed at a specified position in the rice field 102, and then the first connecting plate 602 is twisted to rotate, so that the first fixing rod 601 is rotated to drill into the soil, so that the first fixing rod 601 fixes the butt joint pipe 4 and the joint 5; then, the distribution pipe 7 is laid in the rice field 102 at intervals, so that the distribution pipe 7 and the joint 5 are aligned one by one, and then the sleeve 801 is held and moved to the side close to the joint 5, so that one end of the distribution pipe 7 is sleeved on the joint 5 to complete the docking; then, the second connecting plate 904 is twisted to rotate, so that the second fixing rod 901 is rotated to drill into the soil, so that the second fixing rod 901 is fixed; then, the other end of the distribution pipe 7 is placed between the clamping rod 905 and the groove 903, and then the connecting block 9 is pulled. 02 is moved toward the side close to the clamping rod 905, so that the clamping rod 905 presses the other end of the distribution pipe 7 into the groove 903 of the connecting block 902; then, the two ends of the connecting pipe 3 are docked with the water outlet of the water pump 2 and the docking pipe 4 respectively, and then one end of the distribution pipe 7 is pulled to move, so that the mounting frame 10 and the rotating frame 12 apply thrust to push the cone of the movable rod 15 into the soil, so that the cone of the movable rod 15 and a part of the insertion pipe 13 are inserted into the soil; then The biogas slurry in the liquid storage tank 1 is pumped into the insertion tube 13 by the water pump 2, so that the biogas slurry in the insertion tube 13 squeezes the annular frame 1601 and the movable rod 15 apart, so that the biogas slurry flows out into the soil of the rice field 102 through the gap between the movable rod 15 and the annular column 14, thereby fertilizing the rice seedlings 103 in the rice field 102; thereafter, one end of the distribution pipe 7 is pulled and moved regularly to make the cone of the movable rod 15 and part of the insertion tube 13 penetrate into the soil.
