Description

Technical Field

[0001] The present invention relates to the technical field of water-fertilizer ratio control devices, and in particular to a water-fertilizer integrated water-fertilizer ratio control device and method. Background Art

[0002] Integrated water-fertilizer technology refers to a new agricultural technology that integrates irrigation and fertilization. It uses a pressure system (or natural terrain height difference) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop types. The fertilizer solution is mixed with irrigation water and supplied through a controllable pipeline system. After the water and fertilizer are mixed, sprinkler irrigation or drip irrigation is formed through pipelines and drippers to evenly, regularly and quantitatively infiltrate the crop root development and growth area, so that the main root soil always remains loose and has an appropriate water content. At the same time, according to the fertilizer requirements of different crops, soil environment and nutrient content, the water requirements of crops in different growth periods, and the fertilizer requirements, the needs of different growth periods are designed, and water and nutrients are provided directly to crops in a regular and quantitative manner in proportion.

[0003] The integration of water and fertilizer requires the addition of various fertilizers for mixing, such as nitrogen, phosphorus, and potassium fertilizers, which are mixed with water in a certain proportion to form water-fertilizer integration and irrigate crops. In the process of the fertilizer delivery pipe supplying materials to the fertilizer tank, the top of the fertilizer will be piled up in a cone shape, and the upper surface of the fertilizer is not flat, which makes it difficult for users to intuitively judge the amount of fertilizer, thereby causing ratio errors, and in the process of feeding, part of the fertilizer may be affected by the humid environment and stick to the inner wall of the fertilizer tank, thereby making it impossible for some of the fertilizer remaining in the fertilizer tank to be discharged in time. The above will cause an error between the water-fertilizer regulation ratio and the actual fertilizer input, and the greater the fertilizer input, the greater the error, which is not conducive to the precise adjustment of the water-fertilizer ratio. Therefore, a water-fertilizer ratio control device and method for the integration of water and fertilizer are proposed. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

[0020] Step 1: Adjust the height of the partition in the mixing barrel by rotating the rotating rod. When each mixing barrel is adjusted, connect the water inlet pipe to the water pump, and then start the upper output end of the double-axis motor to drive all the connecting rods to rotate, so that each straight plate drives the L-shaped telescopic rod to move;

[0021] Step 2: The L-shaped telescopic rod pulls the baffle to move through the straight telescopic rod. When the limit groove of the baffle is connected with the bottom end of the feed pipe, the upper output end of the double-axis motor is driven to rotate in the opposite direction, so that the straight plate and the circular hole of the mixing barrel are staggered, and the baffle is connected with the feed pipe through the L-shaped telescopic rod, and then fertilizer is added into the mixing barrel through the feed pipe;

[0022] Step 3: The double-axis motor drives the straight plate to perform linear reciprocating motion, so that the ball head rod vibrates the mixing barrel, so that the fertilizer is flush with the bottom of the partition, and then the double-axis motor moves the straight plate toward the arc plate, so that the L-shaped telescopic rod pushes the baffle to block the feed pipe through the straight telescopic rod, and then the double-axis motor pushes the straight plate toward the mixing barrel again, so that the straight plate and the circular hole of the mixing barrel are connected with each other;

[0023] Step 4: At this time, the baffle plate continues to block the feed pipe, and the double ball rod no longer contacts the arc block. The double ball rod vertically vibrates the mixing barrel, causing the material in the mixing barrel to fall into the mixing barrel. In the process of the straight plate being connected to the circular hole of the mixing barrel, the connecting telescopic plate pushes the valve handle of the control valve, so that the water inlet pipe delivers clean water to the mixing barrel;

[0024] Step 5: When the materials in the mixing barrel are emptied, the upper output end of the double-axis motor drives the arc plates to approach each other, so that the connected telescopic rod pulls the valve handle of the control valve to stop the water inlet pipe, and then the lower output end of the double-axis motor is started to drive the stirring rod to rotate, so that the fertilizer and clean water are mixed to form water fertilizer;

[0025] Step 6: Observe the dissolution state of the fertilizer through a transparent tube and take samples for testing. After the test, open the valve of the drain pipe and drain the water and fertilizer in the mixing barrel through the drain pipe.

[0026] The beneficial effects of the present invention are as follows: the fertilizer ratio of the mixing barrel can be preset through the adjustment component, so that various fertilizers can be mixed with water in a standard ratio and accurate water-fertilizer can be obtained; the dual-axis motor pushes the multiple arc plates away from each other through the multiple connecting rods, so that the multiple springs are in intermittent contact with the ball head rod, thereby the ball head rod can make the mixing barrel vibrate laterally through the first spring, thereby ensuring that the fertilizer in the mixing barrel is flush with the partition; the second ball head rod can provide longitudinal vibration for the mixing barrel, so that the fertilizer will not adhere to the inner wall of the mixing barrel to cause residue, and the fertilizer can all fall into the mixing barrel, thereby ensuring the high accuracy of the water-fertilizer ratio.

[0046] Embodiment 1

[0047] Reference Figure 1-Figure 9 , which is an embodiment of the present invention, provides a water-fertilizer integrated water-fertilizer ratio control device, including: a control unit 100, a proportioning unit 200, a vibration unit 300 and an integrated unit 400;

[0048] Among them, the control unit 100 includes a mixing barrel 101 and four arc-shaped plates 102 slidably arranged on the top of the mixing barrel 101, wherein one side of the three arc-shaped plates 102 is fixedly connected to a straight plate 103, a dual-axis motor 104 is fixedly installed on the top of the inner cavity of the mixing barrel 101, the upper output end of the dual-axis motor 104 passes through the top of the inner cavity of the mixing barrel 101 and is hinged to each arc-shaped plate 102 with a connecting rod 105, the lower output end of the dual-axis motor 104 is fixedly connected to a stirring rod 106, and the bottom of the mixing barrel 101 is fixedly connected to a drain pipe 107.

[0049] The four arc plates 102 are distributed in a circular shape. When the upper output end of the dual-axis motor 104 rotates, each connecting rod 105 will synchronously push the corresponding arc plate 102, so that the four arc plates 102 are equidistantly unfolded. The upper and lower output ends of the dual-axis motor 104 are independently controlled. The lower output end of the dual-axis motor 104 is used to drive the stirring rod 106 to rotate, so that the fertilizer and water are stirred and mixed. A valve is connected to the drain pipe 107, and the mixed water and fertilizer are discharged through the drain pipe 107.

[0050] The proportioning unit 200 includes three pairs of support plates 201 fixedly connected to the top of the mixing barrel 101, and a mixing barrel 202 is fixedly connected to the top of each pair of support plates 201. The bottom of the mixing barrel 202 and the top of the straight plate 103 are both provided with circular holes, and the top of the mixing barrel 101 is provided with a plurality of feeding holes. The proportioning unit 200 also includes an adjustment component 203 for adjusting the fertilizer ratio;

[0051] The vibration unit 300 includes a plurality of spring pieces 301 fixedly connected to both sides of each straight plate 103, a ball head rod 302 is slidably penetrated on one side of each support plate 201, and a first spring 303 is sleeved on each ball head rod 302, a door plate 304 is fixedly connected to one side of each mixing barrel 202, and two double ball rods 305 are slidably penetrated at the bottom of each door plate 304, and a second spring 306 is sleeved on each double ball rod 305, and arc blocks 307 are fixedly connected on both sides of each straight plate 103.

[0052] At the same time, the adjusting component 203 includes a rotating rod 2031 threadedly connected to the top of each mixing barrel 202, the inner cavity of each mixing barrel 202 is slidably provided with a partition 2032, the bottom end of the rotating rod 2031 is rotatably connected to the top of the partition 2032, the top of each mixing barrel 202 is slidably penetrated by a feed pipe 2033 fixedly connected to the top of the partition 2032, the bottom of each partition 2032 is connected to the feed pipe 2033, the top of the mixing barrel 101 is fixedly penetrated by a water inlet pipe 2034, two control valves 2035 are mounted on the water inlet pipe 2034, and a telescopic plate 2036 is hingedly connected between the control valve 2035 located below the water inlet pipe 2034 and one of the arc plates 102.

[0053] The bottom of the mixing barrel 202 and the top of the straight plate 103 are both provided with circular holes. When the four curved plates 102 are in contact with each other, the circular holes of the straight plate 103 and the mixing barrel 202 are staggered. When the four curved plates 102 are away from each other, the curved plates 102 will also push the corresponding straight plates 103 to move relative to each other. When the straight plate 103 and the circular holes of the mixing barrel 202 overlap with each other, the fertilizer in the mixing barrel 202 passes through the two circular holes and the discharge hole of the mixing barrel 101 and enters the mixing barrel 101.

[0054] By rotating the rotating rod 2031, the partition 2032 can be raised and lowered in the mixing barrel 202. The gap between the bottom of the partition 2032 and the bottom of the inner cavity of the mixing barrel 202 is the amount of fertilizer used. By rotating the rotating rod 2031, the partition 2032 can be raised and lowered to different heights in the mixing barrel 202 to adjust the usage ratio between different fertilizers. The feeding pipe 2033 is used to add fertilizer to the mixing barrel 202. The fertilizer transported by the feeding pipe 2033 will pass through the partition 2032 and fall to the bottom of the inner cavity of the mixing barrel 202. At this time, the fertilizer is accumulated in a cone shape and diffuses to the surroundings. At this time, the upper output end of the dual-axis motor 104 slowly drives the connecting rod 105 to deflect, so that multiple straight plates 103 all move linearly through the arc plate 102.

[0055] The end of the ball head rod 302 facing the arc plate 102 is fixedly connected with a round piece, the relative distance between the round piece and the spring piece 301 is less than zero, and the relative distance between the rod surface of the ball head rod 302 and the spring piece 301 is greater than zero. When the straight plate 103 moves, the spring piece 301 will contact the round piece and push the ball head rod 302, so that the round piece and the support plate 201 squeeze the first spring 303. The spring piece 301 is elastic, and then the spring piece 301 is deformed and bent by the interaction force. When the straight plate 103 continues to move, the round piece is out of contact with the spring piece 301, so that The first spring 303 recovers its elasticity and pushes the disc. At this time, the ball end of the ball head rod 302 will repeatedly hit the support plate 201 through the first spring 303, so that each pair of support plates 201 will be hit by the ball head rod 302. When the straight plate 103 continues to move, the disc will contact the second spring piece 301 and then break away from the second spring piece 301 again, thereby generating lateral vibration in a cycle, so that the support plate 201 can receive multiple vibrations from the ball head rod 302, and in this process, the round hole of the straight plate 103 and the mixing barrel 202 will not overlap;

[0056] The support plate 201 transmits the vibration to the mixing barrel 202, so that the fertilizer in the mixing barrel 202 is vibrated and leveled. The mixing barrel 202 is made of transparent material, so that the user can observe whether the fertilizer is flush with the partition 2032. After being flush, no fertilizer is added through the feeding pipe 2033. Then the upper output end of the dual-axis motor 104 rotates in the opposite direction, so that the arc plate 102 drives the straight plate 103 to reset. During the reset of the straight plate 103, multiple springs 301 will contact the round piece in turn, so that the ball head rod 302 continues to hit the support plate 201 for multiple times to ensure that the fertilizer is flush with the partition 2032. The upper output end of the dual-axis motor 104 has a relatively slow speed to avoid the straight plate 103 in the process of linear motion, so as to avoid too fast speed causing the material in the mixing barrel 202 to be shaken and thus break the flatness. The bottom of the mixing barrel 202 can be vibrated smoothly and evenly through multiple ball head rods 302 to ensure that the user can accurately add different fertilizers according to the proportion.

[0057] When the mixing barrel 202 needs to discharge fertilizer, the double-axis motor 104 pushes the straight plate 103 to move. During the movement of the straight plate 103, the bottom of the double ball rod 305 is always in contact with the upper surface of the arc block 307. The weight of the ball at the bottom of the double ball rod 305 is greater than the weight of the ball at the top. When the straight plate 103 moves to the limit, the straight plate 103 and the circular hole of the mixing barrel 202 overlap each other, and the fertilizer in the mixing barrel 202 passes through the discharge hole of the mixing barrel 101 and enters the mixing barrel 101. At the same time, the door plate 30 The two double ball rods 305 on 4 are no longer in contact with the two arc blocks 307. At this time, the double ball rods 305 fall by their own gravity. When the double ball rods 305 fall, the balls on the top of the double ball rods 305 will press the second springs 306 downwards and rebound by the elastic force of the second springs 306. At this time, the balls on the top of the double ball rods 305 will repeatedly hit the top of the inner wall of the door-shaped plate 304, thereby generating longitudinal vibrations, so that the fertilizers sticking to the inner wall of the mixing barrel 202 are shaken off, and at the same time, it can ensure that the fertilizers at the circular hole of the mixing barrel 202 will not be accumulated and blocked;

[0058] When the multiple arc plates 102 move away from each other, the connecting telescopic plate 2036 is pushed by one of the arc plates 102, and the length of the connecting telescopic plate 2036 begins to shorten. When the straight plate 103 begins to overlap with the circular hole of the mixing barrel 202, the connecting telescopic plate 2036 is extended to the limit, and the connecting telescopic plate 2036 no longer extends and opens a valve handle for pushing the control valve 2035, so that the valve of the control valve 2035 is opened. The control valve 2035 located at the top of the water inlet pipe 2034 is used to adjust the water inlet amount. The control valve 2035 allows the user to adjust the water consumption according to the proportion of fertilizers. The control valve 2035 located below the water inlet pipe 2034 is used to control whether water is introduced. When the mixing barrel 202 is discharging fertilizers, the water inlet pipe 2034 discharges water, so that fertilizers and water are discharged at the same time according to a certain proportion.

[0059] When the straight plate 103 moves to reset, the straight plate 103 and the circular hole of the mixing barrel 202 begin to stagger with each other, and the connecting telescopic plate 2036 also begins to be stretched by the arc plate 102. When the straight plate 103 and the circular hole of the mixing barrel 202 are completely staggered with each other, the connecting telescopic plate 2036 stretches to the limit, thereby pulling the valve handle of the control valve 2035, so that the water inlet pipe 2034 no longer enters water. A rotational virtual position is left between the valve handle and the control valve 2035, so that after the control valve 2035 closes the water inlet, the valve handle can still rotate to a certain angle. At the same time, the ball at the bottom of the double ball rod 305 contacts the arc block 307 again, and the double ball rod 305 is squeezed upward and reset through the arc block 307 to facilitate the next vibration use.

[0060] In addition, the top of each straight plate 103 is fixedly connected to an L-shaped telescopic rod 204, and the end of each L-shaped telescopic rod 204 slides through the inner cavity of the corresponding mixing barrel 202. The top of each partition 2032 is slidably provided with a baffle 205, and the top of the baffle 205 is provided with a limiting groove that fits the feed pipe 2033. The top of each baffle 205 is fixedly connected to an L-shaped telescopic rod 206, and the top of each L-shaped telescopic rod 206 is fixedly connected to the corresponding L-shaped telescopic rod 204.

[0061] The straight telescopic rod 206 can be extended and retracted with the lifting and lowering of the partition 2032. The lateral end of the L-shaped telescopic rod 204 is designed to be retractable. A sliding groove that fits the baffle 205 is provided on the top of the partition 2032. When the multiple arc-shaped plates 102 contact each other and form a ring, the baffle 205 blocks the lower end of the feed pipe 2033. When the fertilizer is added to the mixing barrel 202, the straight plate 103 moves toward the mixing barrel 202. At this time, the straight plate 103 drives the L-shaped telescopic rod 204 to move, and the lateral end of the L-shaped telescopic rod 204 is stretched, so that the L-shaped telescopic rod 204 will not pull the straight telescopic rod 206.

[0062] During the movement of the straight plate 103, the round holes of the straight plate 103 and the mixing barrel 202 overlap with each other and stagger after overlapping. Then, as the straight plate 103 continues to move, the lateral end of the L-shaped telescopic rod 204 is stretched to the limit. At this time, the L-shaped telescopic rod 204 pulls the straight telescopic rod 206 to move the baffle 205 along the sliding groove of the partition 2032. When the limiting groove of the baffle 205 is connected to the lower end of the feed pipe 2033, The double-axis motor 104 moves the straight plate 103 toward the arc plate 102, so that the straight plate 103 and the circular hole of the mixing barrel 202 will overlap again and stagger after overlapping. At this time, the lateral end of the L-shaped telescopic rod 204 begins to shorten, but does not push the straight telescopic rod 206, so that the limit groove of the baffle 205 is connected with the lower end of the feed pipe 2033. At this time, fertilizer can be added into the mixing barrel 202 through the feed pipe 2033;

[0063] At this time, the upper output end of the dual-axis motor 104 rotates in the forward and reverse directions at a low speed, while the limit groove of the baffle plate 205 is kept connected with the feed pipe 2033, and the circular hole of the straight plate 103 is staggered with the circular hole of the mixing barrel 202, so that the straight plate 103 performs a linear reciprocating motion, and a rotation virtual position is left between the valve handle and the control valve 2035, so that the connecting telescopic plate 2036 will not open the control valve 2035 of the water inlet pipe 2034, and the ball head rod 302 repeatedly contacts with the multiple spring pieces 301 and hits the support plate 201 to flatten the fertilizer in the mixing barrel 202;

[0064] When the fertilizer is flush with the bottom of the partition 2032, the straight plate 103 moves toward the curved plate 102. At this time, the lateral end of the L-shaped telescopic rod 204 is shortened to the limit and begins to push the straight telescopic rod 206. The baffle 205 is pushed by the straight telescopic rod 206, so that the limit groove of the baffle 205 is no longer connected to the feeding pipe 2033, and the baffle 205 will block the bottom of the feeding pipe 2033 to prevent the feeding pipe 2033 from continuing to add fertilizer. This can prevent the fertilizer attached to the inner wall of the feeding pipe 2033 from accidentally falling into the mixing barrel 202 when the mixing barrel 202 adds fertilizer to the mixing barrel 101, thereby increasing the amount of fertilizer used, thereby causing an error in the water-fertilizer ratio. In addition, the fertilizer above the partition 2032 can be blocked by the baffle 205 to prevent workers from accidentally adding excessive fertilizer.

[0065] When discharge is required, the double-axis motor 104 moves the straight plate 103 toward the mixing barrel 202, so that the circular hole of the straight plate 103 is connected to the circular hole of the mixing barrel 202. At this time, the lateral end of the L-shaped telescopic rod 204 will extend synchronously, but will not pull the straight telescopic rod 206, and the baffle 205 continues to block the bottom of the feed pipe 2033. Through the lateral vibration of the double ball rod 305, the fertilizer in the mixing barrel 202 will not stick to the inner wall of the mixing barrel 202, and then the fertilizer in the mixing barrel 202 will pass through the mixing barrel 202 and the circular holes of the straight plate 103 in turn, and fall into the mixing barrel 101 to mix with clean water.

[0066] Furthermore, the water-fertilizer ratio control device also includes an integrated unit 400, wherein the integrated unit 400 includes a conical cover 401 fixedly connected to the inner wall of the mixing barrel 101, the water inlet pipe 2034 penetrates downward through the conical cover 401, the inner wall of the conical cover 401 is provided with a spiral groove that fits the conical cover 401, the inner wall of the mixing barrel 101 is fixedly connected with a plurality of arc panels 402, the arc surface of each arc panel 402 is provided with a plurality of through holes, one side of the mixing barrel 101 is fixedly connected with a transparent tube 406, and a sealing cover is provided at the top of the transparent tube 406.

[0067] The three mixing barrels 202 can add fertilizers such as nitrogen, phosphorus, and potassium fertilizers according to demand. When the fertilizers in the mixing barrels 202 are added to the mixing barrel 101, the fertilizers will fall into the conical cover 401, and through the conical cover 401, the various fertilizers will move downward along the spiral groove of the conical cover 401 in a spiral manner, thereby enabling the various fertilizers to be pre-mixed to improve the stirring effect. A circular opening is provided at the bottom of the conical cover 401 to allow the mixed fertilizers to fall from the axis of the stirring rod 106, so that the stirring rod 106 can stir;

[0068] While the stirring rod 106 is stirring, the stirring rod 106 mixes the fertilizer and the water. The arc plate 402 can prevent the water and fertilizer from generating a vortex in a rotating state in the mixing barrel 101, so that the water and fertilizer can be passively disturbed by the arc plate 402 to avoid the water and fertilizer rotating along the inner wall of the mixing barrel 101, thereby causing the problem of poor mixing efficiency. A plurality of through holes are provided on the arc plate 402, so that the water and fertilizer are dispersed and mixed again by the through holes, so as to improve the mixing efficiency of the water-fertilizer integration;

[0069] The transparent tube 406 is interconnected with the side of the mixing barrel 101, and the mixed liquid of water and fertilizer in the mixing barrel 101 will flow into the transparent tube 406 to facilitate observation of the dissolution of the fertilizer. The sealing cover on the top of the transparent tube 406 can be removed to facilitate the user to extract the water and fertilizer in the transparent tube 406 for sampling and testing.

[0070] A control method for a water-fertilizer ratio control device, the control method for a water-fertilizer ratio control device is applicable to any of the above water-fertilizer ratio control devices, the control method for a water-fertilizer ratio control device comprises the following steps:

[0071] Step 1: The height of the partition 2032 in the mixing barrel 202 is adjusted by rotating the rotating rod 2031. When each mixing barrel 202 is adjusted, the water inlet pipe 2034 is connected to an external water pump, and then the upper output end of the double-axis motor 104 is started to drive all the connecting rods 105 to rotate, so that each straight plate 103 drives the L-shaped telescopic rod 204 to move;

[0072] Step 2: The L-shaped telescopic rod 204 pulls the baffle plate 205 to move through the straight telescopic rod 206. When the limit groove of the baffle plate 205 is connected with the bottom end of the feed pipe 2033, the upper output end of the double-axis motor 104 is driven to rotate in the opposite direction, so that the straight plate 103 and the circular hole of the mixing barrel 202 are staggered, and the baffle plate 205 is connected with the feed pipe 2033 through the L-shaped telescopic rod 204, and then fertilizer is added into the mixing barrel 202 through the feed pipe 2033;

[0073] Step 3: The double-axis motor 104 drives the straight plate 103 to perform linear reciprocating motion, so that the ball head rod 302 vibrates the mixing barrel 202, so that the fertilizer is flush with the bottom of the partition 2032, and then the double-axis motor 104 moves the straight plate 103 toward the arc plate 102, so that the L-shaped telescopic rod 204 pushes the baffle 205 to block the feed pipe 2033 through the straight telescopic rod 206, and then the double-axis motor 104 pushes the straight plate 103 to move toward the mixing barrel 202 again, so that the straight plate 103 and the circular hole of the mixing barrel 202 are connected to each other;

[0074] Step 4: At this time, the baffle 205 continues to block the feed pipe 2033, and the double ball rod 305 no longer contacts the arc block 307. The double ball rod 305 vertically vibrates the mixing barrel 202, so that the material in the mixing barrel 202 falls into the mixing barrel 101. During the process of the straight plate 103 being connected to the circular hole of the mixing barrel 202, the connecting telescopic plate 2036 pushes the valve handle of the control valve 2035, so that the water inlet pipe 2034 delivers clean water to the mixing barrel 101.

[0075] Step 5: When the materials in the mixing barrel 202 are emptied, the upper output end of the double-axis motor 104 drives the arc plates 102 to approach each other, so that the connected telescopic rod pulls the valve handle of the control valve 2035 to stop the water inlet pipe 2034, and then the lower output end of the double-axis motor 104 is started to drive the stirring rod 106 to rotate, so that the fertilizer and the clean water are mixed to form water fertilizer;

[0076] Step 6: Observe the dissolution state of the fertilizer through the transparent tube 406 and take samples for testing. After the testing is completed, open the valve of the drain pipe 107 to drain the water and fertilizer in the mixing barrel 101 through the drain pipe 107.

[0077] Embodiment 2

[0078] Reference Figure 2 and Fig. 9 The difference from the first embodiment is that: a sieve plate 403 is fixedly connected to the inner wall of the mixing barrel 101, the stirring rod 106 penetrates downwardly through the center of the sieve plate 403, the rod surface of the stirring rod 106 is rotatably connected to a plurality of rollers 404, the rollers 404 are in contact with the upper surface of the sieve plate 403, and the rod surface at the bottom of the stirring rod 106 is fixedly connected to two inclined inclined plates 405, and the two inclined plates 405 are both located at the bottom of the sieve plate 403.

[0079] After the fertilizer particles come into contact with water, they are soaked by water, thus increasing in weight and starting to sink. While the stirring rod 106 is stirring, some undissolved fertilizer particles will naturally sink. The sieve plate 403 can prevent the fertilizer particles from sinking to the bottom quickly, so that the stirring rod 106 can stir the water fertilizer. When some fertilizer particles settle on the sieve plate 403, the stirring rod 106 makes the roller 404 roll on the sieve plate 403, and the roller 404 crushes the fertilizer particles on the sieve plate 403, so that the fertilizer is fully dissolved.

[0080] Some fine fertilizers will pass through the sieve plate 403 and settle to the bottom of the mixing barrel 101. The inclined plate 405 is driven to rotate by the stirring rod 106, so that the inclined plate 405 stirs the fertilizer at the bottom of the mixing barrel 101. The stirring of the inclined plate 405 allows some water to pass through the sieve holes of the sieve plate 403, so that the fertilizer blocked in the sieve holes of the sieve plate 403 is quickly dissolved, thereby improving the rapid solubility of water and fertilizer and forming an integrated water-fertilizer for irrigating crops.

[0081] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
