Description

Technical Field

[0001] The invention relates to the field of agricultural technical equipment, in particular to a large-scale water-soluble fertilizer dissolving device. Background Art

[0002] In the process of the vigorous development of modern agriculture, water-soluble fertilizers have been widely popularized and applied in the cultivation of various crops due to their outstanding advantages such as enabling crops to quickly absorb nutrients, high fertilizer utilization rate, and easy operation. Especially as agriculture is advancing towards scale and intensification, the demand for water-soluble fertilizers by growers has risen sharply like mushrooms after rain. As a result, it is urgent to develop efficient and large-scale water-soluble fertilizer dissolution equipment to effectively meet the current growing agricultural production needs.

[0003] Looking back at the traditional methods of dissolving water-soluble fertilizers, they can be roughly divided into two categories: one is purely manual operation, where workers use handheld tools to stir the water-soluble fertilizers in the container; the other is to use simple mechanical equipment to provide certain assistance, but the core of the operation is still manual. In actual use, the water-soluble fertilizer is first placed in a specific container, then an appropriate amount of water is added, and then the stirring process is started until the water-soluble fertilizer is completely dissolved, and finally a usable water-soluble fertilizer solution is obtained.

[0004] However, these traditional dissolution methods have significant defects at this stage: when a large number of water-soluble fertilizer solids are put into a container at once and then clean water is added to try to dissolve them, there are some disadvantages. On the one hand, the dissolution efficiency is low and often consumes a lot of time. On the other hand, due to the large amount of water-soluble fertilizer solids accumulated in a short period of time, it is very easy to cause agglomeration after the injection of clean water, which hinders the dissolution process. It takes a longer stirring time to ensure that the water-soluble fertilizer is completely dissolved, which undoubtedly seriously slows down the overall rhythm of production and is greatly unfavorable to improving production efficiency.

[0024] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0025] 1. The present invention provides a large-scale water-soluble fertilizer dissolving equipment, which supports the water-soluble fertilizer through a mesh plate. The mesh design of the mesh plate can allow powdered water-soluble fertilizer and water-soluble fertilizer dissolved in water to pass through the mesh smoothly, and granular or flaky water-soluble fertilizer can fully stay on the mesh plate and initially dissolve, effectively preventing premature leakage; in addition, the rotary drive mechanism can be used to make the nozzle reciprocate, so that the water-soluble fertilizer can fully contact with clean water and dissolve, thereby improving the dissolution efficiency.

[0026] 2. The mixing drive mechanism in the present invention causes the stirring paddle to rotate back and forth, and shares the output power with the forward and reverse rotation of the nozzle, saving equipment costs, enabling the stirring paddle to rotate forward and reverse, accelerating the mixing of water-soluble fertilizers, and avoiding the formation of vortex flows; this multi-dimensional power synergy allows the water-soluble fertilizer to be in a dynamic and complex water flow environment in the dissolution barrel at all times, accelerating the dissolution process compared to the traditional single stirring mode.

[0027] 3. The suction system composed of the connecting pipe, the moving rod, the piston, etc. of the present invention generates suction and reverse thrust jets through the reciprocating motion of the piston, which strongly disturbs the solution from bottom to top. This jet further breaks the stratification of the solution, allowing the undissolved water-soluble fertilizer solids to continue to roll and fully contact the solvent, so that even the fertilizer components with poor solubility can be quickly dissolved in the water, and the dissolution uniformity is greatly improved. This process is carried out simultaneously with the horizontal stirring, without the need for additional driving force, and the mechanical structure is used to control the high precision and is easy to use.

[0028] 4. In the present invention, the liquid discharge passage can be quickly opened by pulling the pull rod, thereby realizing rapid discharge of residual liquid, and can be quickly closed, and the structure is reliable.

[0029] In summary, the mesh plate of the present invention allows powdered and dissolved water-soluble fertilizers to pass smoothly, and granular or flaky water-soluble fertilizers are fully retained on it for initial dissolution to prevent leakage; the rotary drive mechanism drives the nozzle to rotate back and forth, so that the water-soluble fertilizer is fully in contact with clean water and the dissolution efficiency is improved; the mixing drive mechanism causes the stirring paddle to rotate back and forth, and shares the dual-output motor power with the nozzle, which not only saves costs, but also accelerates mixing and avoids vortex flow, and multi-dimensional power synergy accelerates dissolution. The present invention can also generate a jet disturbance solution to break the stratification and help the insoluble fertilizer components to be integrated.

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0046] like Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, the large-scale water-soluble fertilizer dissolving equipment includes: a dissolving barrel 1, a mesh plate 101, a liquid discharge port 102, a bracket 2, a shell 3, a fixing ring 301, a dual-output motor 4, a rotating seat 7, a connecting frame 8, a nozzle 11, a water pump 12 and a water pipe 13. The mesh plate 101 is installed in the dissolving barrel 1, and the dissolving barrel 1 is a cylindrical hollow container with an open top. The mesh plate 101 is used to place the water-soluble fertilizer solids, and it is made of stainless steel. This material has good corrosion resistance and high strength, and can withstand the weight of the water-soluble fertilizer solids and the erosion of the liquid during the dissolution process. The surface of the mesh plate 101 is evenly distributed with mesh holes in an array, and the diameter of these mesh holes is smaller than the particle size of the water-soluble fertilizer solid particles, which can effectively prevent the water-soluble fertilizer solid particles from falling directly to the bottom of the dissolving barrel 1, ensuring that the water-soluble fertilizer has enough time to contact and dissolve with water on the mesh plate 101, and can also make the dissolved liquid quickly penetrate through the mesh holes and enter the lower area of ​​the dissolving barrel 1, thereby promoting the efficient conduct of the entire dissolution process. A drain port 102 is installed at the bottom of the side of the dissolving barrel 1. An electric valve is arranged on the drain port 102, which can automatically open the passage according to the setting to discharge the water-soluble fertilizer solution in the dissolving barrel 1. The bracket 2 is installed at the bottom of the dissolving barrel 1. The bracket 2 is divided into three steel frames arranged equidistantly along the circumference, which can stably support the equipment as a whole on the ground. The rotating seat 7 is rotatably installed at the top of the dissolving barrel 1 to ensure the smooth rotation of the rotating seat 7. The connecting frame 8 is installed on the rotating seat 7, and it rotates synchronously with the rotation of the rotating seat 7. The nozzle 11 is installed on the connecting frame 8. There are several nozzles 11, which are equidistantly installed on the connecting frame 8 along the circumference. The water pipe 13 is installed between the output end of the water pump 12 and the nozzle 11. The water pipe 13 adopts a corrosion-resistant rubber water pipe. When in use, the external water tank is connected to the water inlet of the water pump 12. Turning on the water pump 12 can transport clean water along the water pipe 13, and finally spray it on the water-soluble fertilizer at the top of the mesh plate 101 through the nozzle 11. The housing 3 is fixedly connected to the dissolving barrel 1 through two fixing rings 301 arranged in the vertical direction. The fixing ring 301 is made of stainless steel and is firmly fixed to the housing 3 and the dissolving barrel 1 by welding, ensuring the stability of the connection between the housing 3 and the dissolving barrel 1. The housing 3 is a hollow structure, and the dual-output motor 4 is installed in the housing 3. In this embodiment, a worm gear dual-output shaft reduction motor with a model of 5840-31ZYS is selected. One of the output ends of the dual-output motor 4 is connected to a rotating drive mechanism that can drive the connecting frame 8 to rotate back and forth, thereby ensuring that when the dual-output motor 4 is started, the connecting frame 8 can be reciprocated forward and reverse.

[0047] refer to Figure 3 and Figure 4The rotary drive mechanism includes: a turntable 5, a lever 6, an extension arm 9 and a through slot 10. The turntable 5 is rotatably mounted on the top of the housing 3 and is connected to one of the output ends of the dual-output motor 4. The lever 6 is mounted at an eccentric position of the turntable 5 so that the lever 6 can produce a circular motion trajectory when the turntable 5 rotates. The extension arm 9 is mounted on the rotating seat 7, and the through slot 10 is provided on the extension arm 9, and the lever 6 extends into the through slot 10. When the turntable 5 rotates, the circular motion of the lever 6 is utilized to make the lever 6 slide in the through slot 10, thereby driving the extension arm 9 and the connecting frame 8 to reciprocate, thereby causing each nozzle 11 to reciprocate. The length of the through slot 10 is not less than the diameter of the turntable 5, so as to ensure that the lever 6 can be smoothly moved to avoid interference.

[0048] The actual use of the above structure is as follows: before use, first connect the water pump 13 to the external water tank, and then place the water-soluble fertilizer material on the mesh plate 101. Turning on the water pump 12 can make clean water spray out through each nozzle 11, and use the clean water to dissolve the water-soluble fertilizer. The dissolved water-soluble fertilizer flows into the bottom of the inner cavity of the dissolution barrel 1 through the mesh of the mesh plate 101. At the same time, turn on the dual-output motor 4 to drive the turntable 5 connected thereto to rotate. Since the lever 6 is installed in the eccentric position of the turntable 5, the lever 6 performs a circular motion when the turntable 5 rotates. The lever 6 extends into the through slot 10 on the extension arm 9, and the circular motion of the lever 6 is converted into the reciprocating swing of the extension arm 9 through the through slot 10. The extension arm 9 is installed on the rotating seat 7, which in turn drives the rotating seat 7 and the connecting frame 8 to rotate back and forth, so that the nozzle 11 rotates back and forth, so that the clean water is evenly sprayed on the water-soluble fertilizer.

[0049] The device greatly increases the contact probability between water and water-soluble fertilizer solids by adding clean water in a spraying manner, which enables the water-soluble fertilizer to dissolve quickly in the initial stage. At the same time, the rotation of the turntable 5 causes the lever 6 to drive the connecting frame 8 to rotate back and forth, so that the nozzle 11 sprays water back and forth, which can cover all the water-soluble fertilizers and improve the dissolution efficiency.

[0050] refer to Figure 6 The large-scale water-soluble fertilizer dissolving equipment also includes: a stirring paddle 103, which is rotatably installed in the dissolving barrel 1, and the mesh plate 101 is located at the top of the stirring paddle 103. The stirring paddle 103 rotates to further mix the material and solution entering the dissolving barrel 1. However, the continuous rotation of the stirring paddle 103 in the same direction is likely to cause the appearance of vortex flow, affecting the mixing efficiency. To solve this problem, the following solution is proposed. Figure 2 and Figure 5 As shown, the other output end of the dual-output motor 4 is connected to a hybrid driving mechanism capable of driving the stirring paddle 103 to rotate forward and reversely, and the hybrid driving mechanism can drive the stirring paddle 103 to stir the liquid in the dissolving barrel 1 back and forth.

[0051] The hybrid drive mechanism includes: a connecting piece 14, a rotating piece 15, a first connecting column 16, a first gear 17, a second gear 18, a second connecting column 19 and a connecting rod 20. The connecting piece 14 is rotatably mounted at the bottom end of the housing 3 and is connected to the other output end of the dual output motor 4. When the dual output motor 4 is turned on, the connecting piece 14 can be driven to rotate together. The rotating piece 15 is mounted on the lower surface of the connecting piece 14, and the two can rotate synchronously. The first connecting column 16 is mounted at an eccentric position on the lower surface of the rotating piece 15. The first gear 17 is rotatably mounted at the center position of the lower surface of the dissolving barrel 1, and the first gear 17 is connected to the stirring paddle 103, and the two can rotate synchronously. The second gear 18 is rotatably mounted on the lower surface of the dissolving barrel 1, and the second gear 18 is meshed and connected with the first gear 17. When the second gear 18 rotates, the first gear 17 can be driven to rotate. The second connecting column 19 is mounted at an eccentric position on the lower surface of the second gear 18. The two ends of the connecting rod 20 are rotatably connected to the first connecting column 16 and the second connecting column 19 respectively. The specific usage of this structure is as follows: when the other output end of the dual-output motor 4 drives the connecting piece 14 to rotate, the rotating piece 15 installed on the lower surface of the connecting piece 14 rotates synchronously therewith, and since the first connecting column 16 is located at an eccentric position on the lower surface of the rotating piece 15, it performs a circular motion. The two ends of the connecting rod 20 are respectively connected to the rotation of the first connecting column 16 and the second connecting column 19, so that the circular motion of the first connecting column 16 drives the second connecting column 19 to perform synchronous motion, thereby driving the second gear 18 to rotate. Because the second gear 18 is meshed with the first gear 17, and the first gear 17 is connected to the stirring paddle 103, the stirring paddle 103 is finally realized to stir back and forth in the dissolving barrel 1. In addition, the distance between the first connecting column 16 and the center of the rotating piece 15 is smaller than the distance between the second connecting column 19 and the center of the second gear 18. When the rotating disk 15 rotates half a circle and the first connecting column 16 rotates from the farthest end to the closest end of the second gear 18, it can ensure that the connecting rod drives the second gear 18 to rotate less than half a circle, thereby ensuring that the second gear 18 rotates back and forth within the range of half a circle, and then the first gear 17 drives the stirring paddle 103 to stir back and forth, effectively breaking the vortex flow in the solution and improving the mixing efficiency.

[0052] In addition, the large-volume water-soluble fertilizer dissolving equipment also includes: a suction mechanism. Figure 8 , Fig. 9 and Fig.10, the suction mechanism is installed on the dissolving barrel 1, and the suction mechanism is controlled to mix the liquid in the dissolving barrel 1 in the up and down directions. The suction mechanism is symmetrically arranged in two groups to improve the efficiency of mixing in the up and down directions. The suction mechanism includes: a connecting pipe 21, a moving rod 22, a driving block 23, a limiting rod 24, a limiting groove 2401, a piston 25, a suction chamber 26, a fixed seat 27, a discharge port 28, a pull rod 29, a spring 30 and a sealing plug 31. The connecting pipe 21 is fixedly connected to the dissolving barrel 1, and the connecting pipe 21 is L-shaped, and one end of the connecting pipe 21 extends into the bottom end of the inner cavity of the dissolving barrel 1. The moving rod 22 is movably installed in the connecting pipe 21, and the top end of the moving rod 22 extends out of the other end of the connecting pipe 21. The driving block 23 is installed at the top end of the moving rod 22, and the cross-sectional diameter of the driving block 23 is larger than the inner cavity of the connecting pipe 21, which can play a limiting role to prevent the moving rod 22 from excessive displacement. The limiting rod 24 is installed on the side of the driving block 23 facing the dissolving barrel 1, and the limiting groove 2401 is provided on the rotating seat 7, the limiting groove 2401 is arranged obliquely, and the limiting rod 24 extends into the limiting groove 2401. When the rotating seat 7 rotates, the limiting groove 2401 can be driven to rotate synchronously, and then the limiting effect of the limiting groove 2401 on the limiting rod 24 can be used to make the driving block 23 and the moving rod 24 move up and down. The piston 25 is installed at the bottom end of the moving rod 22 and is made of rubber material with good elasticity and sealing. The piston 25 fits tightly with the inner wall of the connecting pipe 21. The cross-sections of the moving rod 22 and the piston 25 are polygonal, and the shape is adapted to the inner cavity cross-section of the connecting pipe 21. The polygonal setting can play a limiting role and prevent the piston 25 and the moving rod 22 from rotating. A suction chamber 26 is formed between the piston 25 and one end of the connecting pipe 21 extending into the dissolving barrel 1. The movement of the moving rod 22 can change the size of the space of the suction chamber 26 to form a suction force or a thrust. The connecting pipe 21 is symmetrically installed with a fixed seat 27 and a discharge port 28 in the upper and lower directions. A pull rod 29 is slidably installed in the fixed seat 27, and the pull rod 29 can move up and down. The bottom end of the pull rod 29 extends into the suction chamber 26. A spring 30 is installed between the pull rod 29 and the fixed seat 27. Pulling the pull rod 29 upward can stretch the spring 30. When the external force is removed, the pull rod 29 can be reset by the tension of the spring 30. A sealing plug 31 is installed at the bottom end of the pull rod 29, and the sealing plug 31 is engaged with the discharge port 28. When the sealing plug 31 is separated from the discharge port 28, the liquid in the suction chamber 26 can be discharged through the discharge port 28.

[0053] The specific use of the above structure is as follows: when the dual output motor 4 is turned on, the connecting frame 8 and the rotating seat 7 rotate synchronously, and the limit groove 2401 rotates back and forth. The limit groove 2401 limits the limit rod 24, so that the driving block 23, the moving rod 22 and the piston 25 can move up and down. When the piston 25 moves upward, the suction chamber 26 expands and sucks the solution in the dissolution barrel 1. On the contrary, when the piston 25 descends, the suction chamber 26 shrinks, and the sucked solution is pushed back into the dissolution barrel 1. The jet formed disturbs the solution in the dissolution barrel 1 from bottom to top, accelerating the mixed dissolution. When the dissolution is completed, after the solution is discharged by the discharge port 102, the pull rod 29 is pulled upward to make the sealing plug 31 leave the discharge port 28, so that the residual liquid in the suction chamber 26 is discharged. After the external force is removed, the tension of the spring 30 is used to make the sealing plug 31 re-block the discharge port 28.

[0054] This structure forms a suction and reverse thrust jet by reciprocating up and down motion of the piston 25 in the connecting pipe 21. Compared with the traditional single stirring method, this jet can strongly disturb the solution from the bottom of the dissolution barrel 1 from bottom to top, so that the water-soluble fertilizer solid particles are in contact with water more fully and frequently. At the same time, this process is carried out synchronously with the horizontal stirring, without the need for additional driving force, and the mechanical structure has high control accuracy and is easy to use. In addition, the drainage passage can be quickly opened by pulling the pull rod 29 to achieve rapid discharge of residual liquid, and can be quickly closed.

[0055] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
