Abstract
Description
Technical Field
[0001] The invention relates to the technical field of fertilizer preparation, and in particular to a water-fertilizer integrated liquid fertilizer preparation device. Background Art
[0002] In modern agricultural production, water-fertilizer integration technology is widely used because it can accurately supply the water and nutrients needed for crop growth, improve the utilization rate of water resources and fertilizers, and reduce environmental pollution. The corresponding liquid fertilizer preparation device has become a key equipment to realize this technology.
[0003] Traditional liquid fertilizer preparation devices have many shortcomings. In the fertilizer ratio link, most lack accurate measurement and control methods, and mainly rely on manual experience to add fertilizers. It is difficult to ensure that the nutrient ratio of the fertilizer prepared each time is consistent, resulting in unstable fertilizer quality, unable to meet the specific nutrient needs of different crops at different growth stages, and affecting the yield and quality of crops.

[0015] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects: The present invention arranges a plurality of gravity sensors on the mounting square plate, which cooperate closely with the feeding assembly, and can monitor the weight changes of solid and liquid fertilizers in real time and accurately. During the preparation process, the user sets the proportion weight of the fertilizer corresponding to each gravity sensor in advance through the controller. Once the gravity sensor detects that the fertilizer on its top is reduced to the set weight, it will immediately send a signal to the controller to close the corresponding solenoid valve and motor, and accurately control the feeding amount of each fertilizer, thereby realizing accurate proportioning of the fertilizers, ensuring the stability and uniformity of the fertilizer quality, and meeting the nutritional needs of different crops at different growth stages.
[0016] The present invention provides a cleaning, crushing and stirring integrated component. Motor 2 drives the rotating tube to rotate at high speed, thereby driving multiple groups of stirring arms and stirring claws to stir the fertilizer in all directions. The stirring arms are distributed at different positions below the bucket cavity. Combined with the multi-angle setting of the stirring claws, the fertilizer can be fully tumbled and mixed in the preparation tank, which greatly improves the mixing efficiency and uniformity, ensures that various nutrients in the liquid fertilizer are evenly distributed, and improves the fertilization effect.
[0017] The present invention plays a key role in the liquid fertilizer discharging process by providing a detachable impurity cover net at the inlet of the discharging bend pipe. The detachable impurity cover net can effectively intercept impurities in the liquid fertilizer and prevent the impurities from entering the preparation tank, thereby ensuring the purity of the prepared liquid fertilizer and preventing impurities from clogging subsequent fertilization equipment (such as sprinklers, drip irrigation systems, etc.), thereby extending the service life of the equipment and ensuring the smooth progress of the fertilization operation.
[0018] The present invention uses a first crushing knife and a second crushing knife that are staggeredly arranged on a rotating tube and are located in a bucket cavity. When solid fertilizer falls into the bucket cavity from a solid material storage bucket, the high-speed rotating crushing knife can quickly and efficiently crush it, and crush larger particles of solid fertilizer into fine particles, which is beneficial to faster dissolution and mixing of the solid fertilizer in a liquid environment, thereby improving the reaction speed and utilization rate of the fertilizer and giving full play to the efficacy of the fertilizer.
[0019] The scrapers on both sides of the mounting plate at the top of the stirring arm of the present invention always rotate in close contact with the inner wall of the preparation tank during the stirring process, so as to timely scrape off the solid fertilizer adhering to the inner wall, avoid fertilizer accumulation and waste, ensure the cleanliness of the interior of the preparation tank, and ensure that the quality of the fertilizer prepared each time is not affected; on the other hand, when cleaning the equipment, the pump body draws cleaning liquid and sprays it through the nozzle on the rotating tube to continuously rinse the preparation tank and the inner wall of the bucket cavity, and cooperates with the motor 2 to drive the rotating tube to rotate, so as to achieve all-round cleaning without dead angles, simple maintenance, and ensure the long-term stable operation of the equipment.

DETAILED DESCRIPTION
[0022] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.
[0023] like Figure 1-Figure 11 As shown, the present invention proposes a water-fertilizer integrated liquid fertilizer preparation device, which includes a preparation tank body 1, a plurality of legs 10 are evenly distributed at the bottom of the preparation tank body 1 for stably supporting the entire device, and a discharge valve pipe 11 is provided at the center of the bottom of the preparation tank body 1 so as to discharge the finished fertilizer after the fertilizer preparation is completed; At the middle of the outer wall of the preparation tank body 1, a mounting circular plate 12 is fixedly installed, and a pair of telescopic cylinders 2 are symmetrically arranged on the mounting circular plate 12. The top of the telescopic rod of each telescopic cylinder 2 is connected to a connecting plate 20, and the connecting plate 20 is firmly connected to the mounting square plate 3 through a number of bolts 21. This connection method not only ensures the stability of the connection, but also facilitates disassembly and maintenance when necessary. Through the telescopic action of the telescopic cylinder 2, the mounting square plate 3 can be driven to move up and down, thereby realizing the adjustment of the working position of the unloading assembly 8 and the cleaning, crushing and stirring integrated assembly 6; A pair of jacks 18 are provided on the top of the preparation tank body 1, and the pair of jacks 18 are used to cooperate with the discharge pipe 37 in the discharge assembly 8. A bucket cavity 16 structure is provided on the inner wall of the preparation tank body 1, and a number of discharge holes 17 are evenly distributed on the inner bottom surface of the bucket cavity 16. These discharge holes 17 are channels for the crushed solid fertilizer to enter the lower part of the preparation tank body 1 for mixing. Discharge bending pipes 14 are symmetrically installed on both sides of the preparation tank body 1, and the outlet position of the discharge bending pipe 14 is just below the bucket cavity 16. A detachable impurity cover net 15 is provided in its inlet, which can effectively filter impurities in the liquid fertilizer and ensure the purity of the liquid fertilizer entering the preparation tank body 1. At the same time, the detachable design facilitates the cleaning and replacement of the impurity cover net 15; Several gravity sensors 31 are evenly distributed on the mounting square plate 3. The unloading assembly 8 includes a bottom plate 1 34 respectively arranged on two relative gravity sensors 31, and a bottom plate 2 35 symmetrically arranged on the other two relative gravity sensors 31. The gravity sensor 31 can monitor the weight change of the object placed above it in real time, and feed back the signal to the control system so as to accurately control the fertilizer ratio; on the bottom plate 1 34, a forward fixing frame 32 is installed, and a liquid material storage hopper 4 is fixedly arranged in the forward fixing frame 32. A solenoid valve 1 40 is installed on the discharge pipe of the liquid material storage hopper 4. By controlling the opening and closing of the solenoid valve 1 40, the unloading amount of the liquid fertilizer can be accurately controlled. The discharge pipe of the liquid material storage hopper 4 is located just above the unloading bend pipe 14 to ensure that the liquid fertilizer can accurately fall into the unloading bend pipe 14 and then enter the preparation tank body 1; a unloading trough 36 is provided on the bottom plate 2 35, and a unloading pipe 37 is correspondingly arranged below the unloading trough 36. A reverse fixing frame 33 is also installed on the bottom plate 35, and a solid material storage hopper 5 is arranged in the reverse fixing frame 33. A solenoid valve 2 50 is installed on the discharge pipe of the solid material storage hopper 5. The discharge pipe is located just above the discharge chute 36. A motor 1 51 is installed on the top of the solid material storage hopper 5. The transmission end of the motor 1 51 extends into the solid material storage hopper 5 and is connected to a transmission shaft 52. A spiral pushing blade 53 is arranged on the outer wall of the transmission shaft 52. When the motor 1 51 is started, the transmission shaft 52 drives the spiral pushing blade 53 to rotate, and pushes the solid fertilizer in the solid material storage hopper 5 downward, and enters the preparation tank body 1 through the discharge chute 36 and the discharge pipe 37; A through slot 38 is provided in the middle of the installation square plate 3. The cleaning, crushing and stirring integrated component 6 includes a second motor 60 arranged on the top of the preparation tank body 1. The second motor 60 is arranged in the through slot 38. The transmission end of the second motor 60 is tightly connected with the rotating tube 610 through a coupling 61 to ensure that the power of the second motor 60 can be efficiently transmitted to the rotating tube 610. The bottom of the rotating tube 610 is movably arranged at the bottom of the preparation tank body 1 through a first sealing bearing 63. The first sealing bearing 63 can not only ensure the flexible rotation of the rotating tube 610, but also effectively prevent fertilizer leakage; a group of first crushing knives 62 and a group of second crushing knives are arranged on the rotating tube 610. The crushing knife 64 and the second crushing knife 64 are located below the first crushing knife 62, and the two are arranged in a staggered distribution. The first crushing knife 62 and the second crushing knife 64 are both located in the bucket cavity 16. When the rotating tube 610 rotates at a high speed driven by the motor 2 60, the crushing knife can fully crush the solid fertilizer falling into the bucket cavity 16. At the same time, the rotating tube 610 is also provided with a scraper 69, and the scraper 69 is tightly arranged on the inner wall of the bucket cavity 16. With the rotation of the rotating tube 610, the scraper 69 can scrape off the solid fertilizer attached to the inner wall of the bucket cavity 16, so that it can smoothly pass through the discharge hole 17 into the lower part of the preparation tank body 1; An array of stirring arms 65 is also provided on the outer wall of the rotating tube 610. The array of stirring arms 65 is located below the bucket cavity 16. Each stirring arm 65 is provided with an array of stirring claws 66. The stirring claws 66 can fully stir and mix the fertilizer under the drive of the stirring arm 65. A mounting plate 67 is provided at the top of the several stirring arms 65 on the same side. Scrapers 68 are symmetrically provided on both sides of the mounting plate 67. The scrapers 68 are closely fitted on the inner wall of the preparation tank body 1. As the stirring arm 65 rotates, the scrapers 68 can scrape and clean the inner wall of the preparation tank body 1 to prevent the fertilizer from sticking to the inner wall. An array of nozzles 611 is symmetrically arranged on the wall of the rotating tube 610. These nozzles 611 are used to spray water or cleaning liquid delivered by the pump body 7. When preparing fertilizer, the water drawn by the pump body 7 is sprayed out through the nozzles 611 to mix with the fertilizer; when cleaning the equipment, the cleaning liquid drawn by the pump body 7 is sprayed out through the nozzles 611 to wash the inner wall of the preparation tank 1 and the bucket cavity 16; A pump body 7 is arranged on the mounting circular plate 12, and an L-shaped tube 70 is connected to the output end of the pump body 7. A second sealing bearing 71 is arranged on a port of the L-shaped tube 70 away from the pump body 7. One end of the rotating tube 610 located outside the bottom of the preparation tank 1 is arranged in the second sealing bearing 71. This connection mode enables the pump body 7 to smoothly transport water or cleaning liquid to the rotating tube 610, and the second sealing bearing 71 ensures the sealing of the connection and the normal rotation of the rotating tube 610. In order to further ensure the stability of the mounting square plate 3 during the up and down movement, a pair of guide columns 30 are symmetrically arranged on both sides of the bottom of the mounting circular plate 12, and a sliding sleeve 13 is arranged at the position corresponding to the guide column 30 on the mounting square plate 3. The guide column 30 is inserted into the sliding sleeve 13. When the telescopic cylinder 2 drives the mounting square plate 3 to move up and down, the cooperation between the guide column 30 and the sliding sleeve 13 can play a good guiding role, prevent the mounting square plate 3 from deflecting or shaking, and ensure the normal operation of the entire device.
[0024] When preparing fertilizer, firstly, solid fertilizer and liquid fertilizer need to be loaded into the solid material storage hopper 5 and liquid material storage hopper 4 respectively. After being ready, start the pump body 7. The pump body 7 extracts an appropriate amount of water according to the required ratio. Under the action of the pump body 7, the water is transported to the rotating tube 610 through the L-shaped tube 70, and then sprayed out from several nozzles 611 on the rotating tube 610 and added to the preparation tank body 1. After the water is added, start the two telescopic cylinders 2 to make their telescopic rods retract synchronously. The telescopic rods drive the installation square plate 3 to move slowly downward until the two discharge pipes 37 are just inserted into the two sockets 18 on the top of the preparation tank body 1 and enter the bucket cavity 16; at the same time, the discharge pipes of the two liquid material storage hoppers 4 are also just inserted into the impurity cover net 15 to prepare for the subsequent fertilizer discharge; Next, the controller sets the weight ratio of the fertilizer corresponding to each gravity sensor 31. After the setting is completed, the controller opens all the solenoid valves 1 40, 2 solenoid valves 50, motor 1 51 and motor 2 60 at the same time. When the two solenoid valves 1 40 are opened, the liquid fertilizer in the liquid storage hopper 4 flows out, is filtered by the impurity cover net 15, flows into the discharge bending pipe 14, and finally enters the preparation tank body 1, while the impurities contained in the liquid fertilizer are intercepted in the impurity cover net 15. When the two solenoid valves 2 50 are opened, the motor 1 51 starts to work, drives the transmission shaft 52 to rotate, and the spiral pusher 53 connected to the transmission shaft 52 rotates accordingly, pushing the solid fertilizer downward along the discharge pipe 37 until the fertilizer falls into the bucket cavity 16. At this time, the motor 2 60 starts The rotating tube 610 rotates at a high speed, and the first crushing knife 62 and the second crushing knife 64 fixed on the rotating tube 610 rotate synchronously, and the falling solid fertilizer is efficiently crushed. The crushed fertilizer falls into the preparation tank body 1 through the discharge hole 17. During the rotation of the rotating tube 610, the scraper 69 installed on the rotating tube 610 also rotates accordingly, and continuously pushes the crushed solid fertilizer on the inner wall of the bucket cavity 16 to ensure that all fertilizers can smoothly pass through the discharge hole 17 and fall into the preparation tank body 1. Once the gravity sensor 31 detects that the corresponding fertilizer on the top is reduced to the set ratio weight, it will immediately send a signal to the controller. After receiving the signal, the controller quickly closes the corresponding solenoid valve and motor on the top to stop the discharge operation of this type of fertilizer. Under the continuous drive of the motor 2 60, the rotating tube 610 drives the stirring arm to rotate, and the fertilizer in the preparation tank 1 is fully stirred and mixed. At the same time, the stirring arm 65 drives the mounting plate 67 to rotate, and the scraper 68 on the mounting plate 67 continuously scrapes the inner wall of the preparation tank 1, effectively preventing the solid fertilizer from adhering to the inner wall of the tank, ensuring the uniformity of the fertilizer mixing. After the fertilizer mixing and preparation is completed, only the discharge valve tube 11 needs to be opened to discharge the prepared fertilizer; When it is necessary to clean the equipment, start the two telescopic cylinders 2 to extend their telescopic rods, driving the mounting square plate 3 to move upward and reset. At this time, the impurity cover net 15 can be easily removed to clean the impurities intercepted by it, and the inside of the unloading bend pipe 14 can also be cleaned. After completing the above cleaning, connect the input end of the pump body 7 to the cleaning liquid, turn on the motor 2 60, and the pump body 7 starts to extract the cleaning liquid and transport it to the rotating tube 610. Driven by the motor 2 60, the rotating tube 610 continues to rotate at a high speed, and the cleaning liquid is forcefully sprayed out from several nozzles 611 on the rotating tube 610, and the preparation tank body 1 and the inner wall of the bucket cavity 16 are all-round and continuously flushed and cleaned to ensure the internal cleanliness of the equipment and prepare for the next fertilizer preparation.
