DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] The present invention provides a root fertilizer applicator for grape planting, such as Figure 1 and Figure 2As shown, it includes a liquid storage tube 1, the top of which is sleeved with a connecting tube 2, the connecting tube 2 is externally connected to the output end of a water pump, and the input end of the water pump extracts fertilizer liquid, and the water pump passes the extracted fertilizer liquid into the interior of the liquid storage tube 1 through the connecting tube 2, and a limiting component for limiting the fertilizer liquid is arranged on the top of the liquid storage tube 1, the bottom of the liquid storage tube 1 is connected with a discharge pipe 3, the discharge port diameter at the bottom of the discharge pipe 3 is smaller than the liquid inlet diameter at the top, a ring edge 4 is arranged at the bottom of the circumferential outer side surface of the liquid storage tube 1, an inner ring 5 is arranged at the top of the liquid inlet of the discharge pipe 3, and the discharge pipe 3 is spirally clamped at the bottom of the liquid storage tube 1 using the inner ring 5, the bottom of the liquid storage tube 1 is sleeved with a collar 6, one side of the collar 6 is connected to a pressing plate 7, a nut 8 is arranged on the top of the collar 6, the nut 8 is spirally sleeved on the surface of the liquid storage tube 1, and the spiral cooperation of the nut 8 and the liquid storage tube 1 makes the bottom surface of the collar 6 fit tightly with the top surface of the collar 4. The top of the drain pipe 3 is connected to the bottom of the liquid storage pipe 1 by rotating the collar 6, and the collar 6 is rotated by the pressing plate 7 so that the position of the pressing plate 7 corresponds to the farmer's foot. The nut 8 is tightened, and the nut 8 moves down on the surface of the liquid storage pipe 1. The downwardly moved nut 8 cooperates with the ring edge 4 to clamp the collar 6 to prevent the collar 6 from rotating on the surface of the liquid storage pipe 1, so as to facilitate the matching of the pressing plate 7 with the applicable feet of different farmers. The bottom of the drain pipe 3 is matched with the root of the grape plant, and the farmer's foot steps on the top surface of the pressing plate 7. The pressure of the foot on the pressing plate 7 causes the collar 6 to use the ring edge 4 to move the liquid storage pipe 1 and the drain pipe 3 downward. The downwardly moved drain pipe 3 is gradually inserted into the soil under the pressure of the foot until the bottom surface of the ring edge 4 of the liquid storage pipe 1 contacts the ground. Start the water pump, open the limiting component, and draw fertilizer liquid from the water pump input end, and the fertilizer liquid passes into the connecting pipe 2 through the water pump output end. Since the limiting component is in the open state, the fertilizer liquid in the connecting pipe 2 passes into the liquid storage pipe 1. The liquid storage pipe 1 uses the discharge port at the bottom of the discharge pipe 3 to discharge the fertilizer liquid to the roots of the grape plants, thereby completing the root fertilization treatment of the grape planting.

[0027] After fertilization is completed, close the limiting component, which blocks the liquid storage tube 1, pull the drainage tube 3 out of the soil, and match the bottom end of the drainage tube 3 with the root of the next grape plant. Reinsert the drainage tube 3 into the soil by stepping on it, so that the fertilizer liquid can pass through the drainage tube 3 to fertilize different grape plants.

[0028] exist Figure 1 and Figure 3In the figure, a clamping component for clamping the bottom end of the connecting tube 2 is arranged at the top end of the liquid storage tube 1, and the connecting tube 2 is made of soft material. The clamping component includes two opposite arc plates 9, and the inner concave surface of the arc plate 9 corresponds to the circumferential outer surface of the connecting tube 2. A clamping ring 10 is connected to the bottom end of the arc plate 9, and the inner surface of the clamping ring 10 is connected to the circumferential outer surface of the liquid storage tube 1 by means of a first spring 11. The elastic force of the first spring 11 enables the clamping ring 10 to drive the inner concave surface of the arc plate 9 to fit the circumferential outer surface of the connecting tube 2. Pull the clamp ring 10 away from the liquid storage tube 1, the moving clamp ring 10 cooperates to pull the first spring 11, and the connecting tube 2 is connected to the top of the liquid storage tube 1 by deformation. The tension applied to the clamp ring 10 is released, and the elastic force of the first spring 11 uses the clamp ring 10 to make the arc plate 9 close to the liquid storage tube 1 until the inner concave surface of the arc plate 9 fits with the outer circumferential surface of the connecting tube 2. The initial clamping effect of the connecting tube 2 is completed by limiting the elastic force of the first spring 11.

[0029] exist Figure 3 and Figure 4 In the embodiment, the inner side of the clamp ring 10 is fixed with an inner tube 12 that penetrates the liquid storage tube 1. A rotating rod 13 is inserted through the centers of the two inner tubes 12. An inner thread is provided on the inner wall of the inner tube 12. A threaded portion is provided on the outer side of the circumference of the rotating rod 13. The rotating rod 13 is spirally engaged with the inner tube 12 by means of the threaded portion. The rotating rod 13 is spirally clamped inside the inner tube 12. The inner threads of the two inner tubes 12 are in opposite directions. The rotating rotating rod 13 makes the two inner tubes 12 approach or move away from each other. A semicircular plate 14 is provided inside the liquid storage tube 1. The semicircular plate 14 is located on one side of the rotating rod 13. A limiting ring 15 that is sleeved with the surface of the rotating rod 13 is fixed on the side of the semicircular plate 14. An inserting rod 16 is spirally inserted at the center of the limiting ring 15. A slot corresponding to the inserting rod 16 is provided on the surface of the rotating rod 13. The semicircular plate 14 carrying the limiting ring 15 is placed inside the liquid storage tube 1, the clamp ring 10 is pulled away from the liquid storage tube 1, and the rotating rod 13 is rotated to pass through the clamp ring 10 and the inner tube 12. Since the rotating rod 13 is spirally matched with the inner tube 12, until the end of the rotating rod 13 enters the liquid storage tube 1, the moving rotating rod 13 gradually passes through the limiting ring 15 until the bottom end of the rotating rod 13 corresponds to the inner side end of the other inner tube 12, the rotating rotating rod 13 is continued to be rotated, and the rotating rotating rod 13 gradually enters the other inner tube 12, and the tension applied to the clamp ring 10 is released. At this time, the end of the rotating rotating rod 13 gradually passes through the two inner tubes 12, and the rotating threaded part makes the two opposite inner tubes 12 gradually approach until the slot at the center of the rotating rod 13 is inside the limiting ring 15, and the inserted rod 16 is spirally inserted through the limiting ring 15. At this time, the inner end of the inserted rod 16 is spirally clamped in the slot of the rotating rod 13 to complete the limitation of the semicircular plate 14.

[0030] The rotating rod 13 continues to rotate, and the rotating rotating rod 13 causes the inner tube 12 to separate from the threaded portion. At this time, the elastic force of the first spring 11 causes the two opposite arc plates 9 to approach the liquid storage tube 1, and the connecting tube 2 is sleeved on the top of the liquid storage tube 1. The elastic force of the first spring 11 causes the inner concave surface of the arc plate 9 to fit the outer circumferential surface of the connecting tube 2, and the elastic force of the first spring 11 causes the inner thread of the inner tube 12 to contact the threaded portion of the rotating rod 13. When the fertilizer liquid passes through the liquid storage tube 1, the fertilizer liquid causes the semicircular plate 14 to rotate inside the liquid storage tube 1. The rotating semicircular plate 14 uses the insertion rod 16 on the limiting ring 15 to rotate the rotating rod 13. The rotating rotating rod 13 uses the threaded portion to make the two opposite inner tubes 12 approach each other. The moving inner tube 12 causes the arc plate 9 to clamp the connecting tube 2 through the clamp ring 10. During the flow of the fertilizer liquid, the connection stability between the connecting tube 2 and the liquid storage tube 1 is improved, and the connection tube 2 and the liquid storage tube 1 are prevented from being separated during the flow of the fertilizer liquid.

[0031] exist Figures 5 to 7 In the embodiment, the limiting component includes a sliding sleeve 17, the outer circumferential surface of the sliding sleeve 17 is in contact with the inner wall of the liquid storage tube 1, the side wall of the liquid storage tube 1 is provided with a side groove 18, the outer circumferential surface of the liquid storage tube 1 is provided with a plate 19 for blocking the side groove 18, the outer circumferential surface of the sliding sleeve 17 is connected to the inner concave surface of the plate 19 by a connecting plate, and a pull bar 20 is provided on the top of the outer convex surface of the plate 19. Pull the pull bar 20 upward, the upward pull bar 20 uses the plate 19 to pull the sliding sleeve 17 upward inside the liquid storage tube 1, the upward plate 19 always blocks the side groove 18 to prevent the fertilizer liquid inside the liquid storage tube 1 from leaking, and the upward plate 19 uses the connecting plate to move upward inside the side groove 18 until the top surface of the connecting plate is in contact with the inner top surface of the side groove 18.

[0032] An inner frame 21 is embedded in the center of the sliding sleeve 17, and a plurality of leakage grooves 22 are arranged in an annular manner on the outer side of the inner frame 21. The sliding sleeve 17 cooperates to block the plurality of leakage grooves 22. A plurality of side plates 23 are fixed to the bottom of the outer side of the inner frame 21, and the inner frame 21 is connected to the inner wall of the liquid storage tube 1 by using the plurality of side plates 23. A plurality of vertical rods 24 are fixed to the bottom of the sliding sleeve 17, and the plurality of vertical rods 24 correspond to the plurality of side plates 23 one by one, and the vertical rods 24 pass through the center of the side plates 23. A second spring 25 is sleeved on the surface of the vertical rod 24, and the top end of the second spring 25 is connected to the bottom surface of the side plate 23, and the bottom end of the vertical rod 24 is connected to a circular plate, and the bottom end of the second spring 25 is connected to the top surface of the circular plate. When the sliding sleeve 17 moves upward, since the inner frame 21 is clamped in the liquid storage tube 1 by a plurality of side plates 23, the upward sliding sleeve 17 moves upward on the surface of the inner frame 21, and the sliding sleeve 17 gradually moves to the top of the plurality of leakage grooves 22. The fertilizer liquid in the liquid storage tube 1 enters the drain pipe 3 through the plurality of leakage grooves 22, and the fertilizer liquid is injected into the roots of the grape plants by the discharge port of the drain pipe 3, thereby completing the fertilization of the roots of the grape plants.

[0033] The upward sliding sleeve 17 drives multiple vertical rods 24 to move upward synchronously. The upward vertical rod 24 uses a circular plate to cooperate with the second spring 25 on the surface of the vertical rod 24 to complete the injection of the fertilizer liquid. The tension applied to the pull rod 20 is released, and the elastic force of the multiple second springs 25 causes the sliding sleeve 17 to move downward. The downward sliding sleeve 17 gradually blocks the multiple leakage grooves 22 on the surface of the inner frame 21 until the connecting plate fits with the inner bottom surface of the side groove 18. At this time, the sliding sleeve 17 blocks the leakage groove 22, and the fertilizer liquid at the bottom of the sliding sleeve 17 is injected into the soil through the drainage pipe 3, and the drainage pipe 3 is pulled out of the soil.

[0034] exist Figure 1 and Figure 7 In the embodiment, a handle 26 is fixed on the outer side of the circumference of the liquid storage tube 1. The handle 26 is located at the top of the pull bar 20. A limiting rod 27 penetrating the handle 26 is fixed on the top surface of the plate 19. An elastic member 28 is sleeved on the surface of the limiting rod 27. The top of the elastic member 28 is connected to the handle 26, and the bottom of the elastic member 28 is connected to the top surface of the plate 19. The farmer holds the handle 26, and uses the handle 26 to match the bottom end of the drainage tube 3 with the soil at the root of the grape plant. The drainage tube 3 is inserted into the soil by stepping on the pressure plate 7. The index finger pulls the pull bar 20 upward. The upward pull bar 20 uses the plate 19 to squeeze the elastic member 28 on the surface of the limiting rod 27 until the fertilizer liquid enters the soil through the drainage tube 3. The pulling force on the pull bar 20 is released, and the elastic force of the elastic member 28 makes the plate 19 away from the handle 26, which is convenient for the plate 19 to reset.

[0035] Working principle of the present invention:

[0036] Reference Figures 1 to 7 As shown, the semicircular plate 14 carrying the limiting ring 15 is placed inside the liquid storage tube 1, the clamp ring 10 is pulled away from the liquid storage tube 1, and the rotating rod 13 is rotated to pass through the clamp ring 10 and the inner tube 12. Since the rotating rod 13 is spirally matched with the inner tube 12, until the end of the rotating rod 13 enters the liquid storage tube 1, the moving rotating rod 13 gradually passes through the limiting ring 15 until the bottom end of the rotating rod 13 corresponds to the inner side end of the other inner tube 12, the rotating rotating rod 13 continues to be rotated, and the rotating rotating rod 13 gradually enters the other inner tube 12, and the tension applied to the clamp ring 10 is released. At this time, the end of the rotating rotating rod 13 gradually passes through the two inner tubes 12, and the rotating threaded part makes the two opposite inner tubes 12 gradually approach until the slot at the center of the rotating rod 13 is inside the limiting ring 15, and the inserted rod 16 is spirally inserted through the limiting ring 15. At this time, the inner end of the inserted rod 16 is spirally clamped in the slot of the rotating rod 13, completing the limitation of the semicircular plate 14.

[0037] The rotating rod 13 continues to rotate, and the rotating rotating rod 13 separates the inner tube 12 from the threaded portion. At this time, the elastic force of the first spring 11 makes the two opposite arc plates 9 approach the liquid storage tube 1, and the connecting tube 2 is sleeved on the top of the liquid storage tube 1. The elastic force of the first spring 11 makes the inner concave surface of the arc plate 9 fit with the outer circumferential surface of the connecting tube 2, and the elastic force of the first spring 11 makes the internal thread of the inner tube 12 contact the threaded portion of the rotating rod 13. The farmer holds the handle 26 and uses the handle 26 to align the bottom end of the drainage pipe 3 with the soil at the root of the grape plant. The farmer uses the pressure plate 7 to insert the drainage pipe 3 into the soil. The index finger pulls the pull rod 20 upward. The upward pull rod 20 uses the adhesive plate 19 to squeeze the elastic member 28 on the surface of the limiting rod 27. The upward pull rod 20 uses the adhesive plate 19 to pull the sliding sleeve 17 upward inside the liquid storage pipe 1. The upward sliding sleeve 17 moves upward on the surface of the inner frame 21. The sliding sleeve 17 gradually moves to the top of the multiple leakage grooves 22. The fertilizer liquid inside the liquid storage pipe 1 enters the drainage pipe 3 through the multiple leakage grooves 22. The drainage port of the drainage pipe 3 is used to inject the fertilizer liquid into the root of the grape plant. The pulling force on the pull rod 20 is released. The elastic force of the elastic member 28 makes the adhesive plate 19 away from the handle 26, which is convenient for the adhesive plate 19 and the pull rod 20 to reset.

[0038] When the fertilizer liquid passes through the liquid storage tube 1, the fertilizer liquid causes the semicircular plate 14 to rotate inside the liquid storage tube 1. The rotating semicircular plate 14 uses the insertion rod 16 on the limiting ring 15 to rotate the rotating rod 13. The rotating rotating rod 13 uses the threaded portion to make the two opposite inner tubes 12 approach each other. The moving inner tube 12 allows the arc plate 9 to clamp the connecting tube 2 through the clamping ring 10. During the flow of the fertilizer liquid, the connection stability between the connecting tube 2 and the liquid storage tube 1 is improved, and the connection tube 2 and the liquid storage tube 1 are prevented from separating during the flow of the fertilizer liquid.

[0039] After fertilization is completed, close the limiting component, which blocks the liquid storage tube 1, pull the drainage tube 3 out of the soil through the handle 26, and make the bottom end of the drainage tube 3 correspond to the root of the next grape plant. The drainage tube 3 is reinserted into the soil by stepping on it, so that the fertilizer liquid can pass through the drainage tube 3 to fertilize different grape plants.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
