A fruit tree nutrient solution preparation device

Abstract

This invention relates to the technical field of nutrient solution preparation, and more particularly to a device for preparing fruit tree nutrient solution. It includes: a tank; a controller installed on the outer wall of the tank; a column connected to the inner bottom of the tank; a rotating rod rotatably connected to the column; a first motor installed on the top of the tank, with its output shaft connected to the top of the rotating rod; a swing block rotatably connected at intervals inside the rotating rod; a stirring rod symmetrically connected to both sides of the swing block; and a fixing ring connected at intervals to the column. This invention uses the rotating rod to drive the swing block to rotate, and the protruding rod slides within the corrugated groove of the fixing ring, causing the swing block and stirring rod to intermittently swing forward and backward while revolving with the rotating rod. This significantly expands the shearing and disturbance range of the stirring rod, breaking the limitation of stirring only in a horizontal area, significantly enhancing the convection effect of the upper and lower layers of liquid in the tank, and effectively preventing concentration stratification caused by large differences in flow velocity.

Description

Technical Field

[0001] This invention relates to the technical field of nutrient solution preparation, and more particularly to a device for preparing nutrient solution for fruit trees. Background Technology

[0002] In modern fruit tree cultivation and precision agriculture, integrated water and fertilizer technology has become a key means to improve fruit quality and yield. The uniformity of the nutrient solution preparation directly determines the fertilization effect. Currently, most existing nutrient solution preparation devices adopt a vertical tank structure with a rotating stirring rod at the center. The rotation of the blades drives the liquid flow to achieve mixing. However, this traditional stirring method has gradually revealed significant technical limitations in practical applications.

[0003] Because the effective range of the stirring blades is mainly limited to their rotation radius and surrounding horizontal area, the fluid shear force and circulation velocity are significantly insufficient in areas such as the tank edges, bottom corners, and areas far from the blades. This makes it difficult for the liquid inside the tank to form effective convection in all directions, easily leading to large differences in flow velocity between the upper and lower layers of liquid and uneven concentration distribution, thus forming obvious stratification. This problem is particularly prominent when preparing high-viscosity nutrient solutions or mixtures containing a high proportion of suspended solid particles (such as micronutrient fertilizers, organic matter, etc.). Gravity causes denser solid particles or viscous components to settle rapidly to the bottom, while the upper liquid is relatively thin, resulting in a heterogeneous state of "clear upper layer and thick lower layer." This concentration stratification phenomenon causes the initial liquid concentration discharged from the unit to be low, while the later liquid concentration is too high, resulting in drastic fluctuations in the output nutrient solution concentration. For fruit trees that are highly sensitive to nutrients, this uneven fertilization not only fails to achieve the goal of precise nutrient supplementation, but may also cause root burn due to excessively high local concentrations, or lead to malnutrition due to excessively low concentrations, which will seriously restrict the level of precision in fruit tree planting and economic benefits. Summary of the Invention

[0004] In view of this, the present invention provides a fruit tree nutrient solution preparation device, which can overcome the shortcomings of existing nutrient solution preparation devices, which have limited range of action of stirring blades, resulting in uneven flow rate and concentration of liquid between the upper and lower layers, easy formation of stratification, especially under high viscosity or high solid content conditions, large fluctuation of liquid concentration, and inability to meet the requirements of uniformity of precise fertilization of fruit trees.

[0005] Technical solution: A fruit tree nutrient solution preparation device, comprising: a tank; a controller installed on the outer wall of the tank; a column connected to the inner bottom of the tank; a rotating rod rotatably connected to the column; a first motor installed on the top of the tank, with the output shaft of the first motor connected to the top of the rotating rod; a swing block rotatably connected at intervals inside the rotating rod; a stirring rod symmetrically connected to both sides of the swing block; a fixing ring connected at intervals to the column, with corrugated grooves on the outer wall of the fixing ring; a protruding rod connected to the swing block, with the end of the protruding rod located within the corrugated groove; and a stirring assembly disposed within the tank for stirring the raw materials within the tank.

[0006] Furthermore, it is particularly preferred that the agitation assembly includes: a first rotating disk rotatably connected to the inner side of the tank; an agitating scraper connected to the top of the first rotating disk and in contact with the inner wall of the tank; and a rotation mechanism disposed inside the tank for driving the first rotating disk to rotate.

[0007] Furthermore, it is particularly preferred that the rotating mechanism includes: a driving gear connected to the lower end of the rotating rod; a first rotating rod symmetrically rotatably connected to the lower end of the column; a first gear connected to the first rotating rod and meshing with the driving gear; a second rotating rod symmetrically rotatably connected to the inner bottom of the tank; a second gear connected to the second rotating rod; a driven gear ring connected to the first rotating disk and meshing with the second gear; and a pulley assembly disposed between the first rotating rod and the second rotating rod, so that the first rotating rod and the second rotating rod can be driven through the pulley assembly.

[0008] Furthermore, particularly preferably, it also includes: a support base connected to the top of the tank; an annular hollow slide block slidably connected to the support base, with the lower part of the annular hollow slide block slidably connected to and maintaining communication with the tank; a weight sensor installed on the top of the support base, with the top of the weight sensor in contact with the annular hollow slide block; a loading cylinder connected to and maintaining communication with the top of the annular hollow slide block; a grinding assembly disposed inside the loading cylinder for grinding the raw materials inside the loading cylinder; a dispersing assembly disposed on the grinding assembly for dispersing the raw materials inside the loading cylinder; and a metering assembly disposed inside the loading cylinder for metering the raw materials inside the loading cylinder.

[0009] Furthermore, it is particularly preferred that the grinding assembly includes: a fixed disk connected to the inner wall of the loading cylinder; a second motor mounted on the fixed disk; a grinding disc connected to the output shaft of the second motor; and grinding strips circumferentially spaced and connected to the inner wall of the loading cylinder, with the bottom of the grinding strips contacting and engaging with the top of the grinding disc.

[0010] Furthermore, it is particularly preferred that the dispersing component includes: a connecting rod connected to the top of the grinding disc; and a stirring rack connected to the connecting rod.

[0011] Furthermore, it is particularly preferred that the metering component includes: a conical disc connected to the inner wall of the feeding cylinder, and the conical disc having a first opening; a second rotating disc connected to the connecting rod, and the second rotating disc having symmetrically opened second openings; and an annular airbag installed on the inner wall of the feeding cylinder, with a gap between the annular airbag and the grinding disc.

[0012] Furthermore, it is particularly preferred that the device also includes an annular air tube connected to the inner wall of the filling cylinder, and the annular air tube is located below the annular air bladder.

[0013] Beneficial effects: 1. The present invention drives the swing block to rotate by rotating the rod, and the convex rod slides in the corrugated groove of the fixed ring, which drives the swing block and the stirring rod to swing intermittently forward and backward while revolving with the rotating rod. This can greatly expand the shear and disturbance range of the stirring rod, break the limitation of stirring only in the horizontal area, significantly enhance the convection effect of the upper and lower liquids in the tank, and effectively prevent the concentration stratification phenomenon caused by large differences in flow rate.

[0014] 2. The rotating rod of the present invention drives the first rotating disk and the stirring scraper to rotate in opposite directions through the transmission of the drive gear, the first gear, the pulley assembly and the second gear. The spiral structure at the bottom of the stirring scraper can stir up the thick components or solid particles deposited at the bottom of the tank, forming a reverse shearing engagement with the upper stirring rod, forcing the liquid in the whole tank to form a three-dimensional circulation flow. Especially under high viscosity or high solid content conditions, it ensures that the concentration of the liquid in the upper and lower layers is uniform and consistent, avoiding the problem of concentration fluctuation that is thin at the beginning and thick at the end. In addition, the stirring scraper can scrape and clean the inner wall of the tank to prevent the raw materials from sticking together.

[0015] 3. This invention uses a second motor to drive the grinding disc and the second rotating disc to rotate, which can intermittently feed the raw material on the conical disc to the grinding area in a quantitative manner. The grinding disc and grinding strip work together to grind the raw material into fine particles before it falls into the tank. At the same time, a weight sensor monitors the amount of material fed in real time. When the preset value is reached, the annular airbag is controlled to expand and block the feeding channel. This structure can not only realize the automatic weighing and uniform feeding of solid raw materials, avoiding the direct addition of lumpy raw materials that would lead to uneven dissolution, but also ensure the stability of the nutrient solution concentration from the source by precisely controlling the amount of material fed, thus meeting the uniformity requirements of precision fertilization for fruit trees.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example: A device for preparing nutrient solution for fruit trees, such as... Figures 1-6As shown, the device includes a tank 1, a controller 2, a column 3, a rotating rod 4, a first motor 5, a swing block 6, a stirring rod 7, a fixing ring 8, a protruding rod 9, and a stirring assembly. An inlet valve and an outlet valve are installed on the left side of the outer wall of the tank 1. The controller 2 is installed on the lower right side of the outer wall of the tank 1. The column 3 is connected to the middle of the inner bottom of the tank 1, and the rotating rod 4 is rotatably connected to the column 3. The first motor 5 is installed in the middle of the top of the tank 1, and the output shaft of the first motor 5 is connected to the top of the rotating rod 4. The rod 4 has multiple swing blocks 6 rotatably connected from top to bottom inside. Each swing block 6 has a stirring rod 7 symmetrically connected to both sides. The column 3 has multiple fixing rings 8 rotatably connected from top to bottom. Each fixing ring 8 corresponds to a swing block 6 and is located inside the swing block 6. Each fixing ring 8 has a corrugated groove 801 on its outer wall. Each swing block 6 has a protruding rod 9 connected to its inner side, and the end of the protruding rod 9 is located inside the corrugated groove 801. The tank 1 is also equipped with a stirring component for stirring the raw materials.

[0029] like Figure 5 and Figure 6 As shown, the agitation assembly includes a first rotating disk 10, an agitating scraper 11, and a rotation mechanism. The first rotating disk 10 is rotatably connected to the lower inner side of the tank body 1, and the agitating scraper 11 is connected to the top of the first rotating disk 10. The lower part of the agitating scraper 11 has a spiral structure, and the agitating scraper 11 contacts the inner wall of the tank body 1. A rotation mechanism for driving the first rotating disk 10 to rotate is provided inside the tank body 1. The rotation mechanism includes a driving gear 12, a first rotating rod 13, a first gear 14, a second rotating rod 15, a second gear 16, a driven gear ring 17, and a pulley assembly 18. The lower end of the rotating rod 4 is connected to the driving gear 12, and the lower end of the column 3 is symmetrically rotatably connected to two first rotating rods. The moving rod 13 has two first rotating rods 13 connected to first gears 14, which mesh with the driving gear 12. The inner bottom of the tank body 1 is symmetrically connected to two second rotating rods 15, each connected to a second gear 16. The lower part of the first rotating disk 10 is connected to a driven gear ring 17, which meshes with the second gear 16. The pulley assembly 18 consists of two pulleys and a flat belt. The two pulleys are respectively connected to the upper parts of the first rotating rods 13 and the second rotating rods 15. The flat belt is wound between the two pulleys so that the first rotating rods 13 and the second rotating rods 15 can be transmitted through the pulley assembly 18.

[0030] When the device is needed, the raw materials are first placed into the tank 1 in a certain proportion. Then, the controller 2 controls the first motor 5 to start working. The first motor 5 drives the rotating rod 4 to rotate, which in turn drives the swing block 6 to rotate. The swing block 6 drives the convex rod 9 to slide in the corrugated groove 801 of the fixed ring 8. Due to the guidance of the corrugated groove 801, the convex rod 9 moves up and down intermittently while revolving with the swing block 6, thereby causing the swing block 6 to produce regular forward and reverse swings. This, in turn, drives the stirring rod 7 to swing up and down on the basis of horizontal rotation, significantly expanding the stirring range of the stirring rod 7, so that its working area is no longer limited to a single plane of rotation. At the same time, the rotating rod 4 drives the drive gear 12 to rotate, and the drive gear 12 and the first gear 14... The first rotating rod 13 is driven to rotate, and the first rotating rod 13 transmits power to the second rotating rod 15 through the pulley assembly 18, which drives the second gear 16 to rotate. The second gear 16 meshes with the driven gear ring 17, driving the first rotating disk 10 and the stirring scraper 11 to rotate. The rotation direction of the stirring scraper 11 is opposite to that of the rotating rod 4, forming a reverse shearing effect, which effectively enhances the turbulence of the liquid in the tank 1 and ensures that the raw materials are mixed more evenly. In addition, the lower part of the stirring scraper 11 has a spiral structure, which can stir the raw materials at the bottom of the tank 1 upward during rotation to avoid the deposition of solid particles. At the same time, the stirring scraper 11 keeps in contact with the inner wall of the tank 1 and can scrape and clean the inner wall during stirring to prevent the raw materials from sticking together.

[0031] like Figure 1 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, it also includes a support base 19, an annular hollow slide 20, a weight sensor 21, a loading cylinder 22, a grinding component, a dispersing component, and a metering component. The top of the tank 1 is connected to the support base 19, and the annular hollow slide 20 is slidably connected to the support base 19. The top and bottom of the annular hollow slide 20 are both open-type designs, and the lower part of the annular hollow slide 20 slides through the top of the tank 1 and maintains communication with the interior of the tank 1. The weight sensor 21 is installed on the top of the support base 19, and the top of the weight sensor 21 contacts the annular hollow slide 20. The top of the annular hollow slide 20 is connected to the loading cylinder 22 and maintains communication. The loading cylinder 22 is equipped with a grinding component for grinding raw materials, and the grinding component is equipped with a dispersing component for dispersing raw materials. The loading cylinder 22 is also equipped with a metering component for metering the raw materials.

[0032] like Figure 8As shown, the grinding assembly includes a fixed disk 23, a second motor 24, a grinding disk 25, and grinding strips 26. The fixed disk 23 is connected to the lower inner wall of the loading cylinder 22. The second motor 24 is installed in the middle of the fixed disk 23. The grinding disk 25 is connected to the output shaft of the second motor 24. The top of the grinding disk 25 is conical. Multiple grinding strips 26 are circumferentially spaced on the lower inner wall of the loading cylinder 22, and the bottom of the grinding strips 26 contacts and engages with the top of the grinding disk 25.

[0033] like Figure 8 As shown, the dispersing assembly includes a connecting rod 27 and a stirring rack 28. The top of the grinding disc 25 is connected to the connecting rod 27, and the stirring rack 28 is connected to the connecting rod 27.

[0034] like Figures 8-10 As shown, the metering component includes a conical disc 29, a second rotating disc 30, and an annular airbag 31. The conical disc 29 is connected to the lower inner wall of the feeding cylinder 22. The conical disc 29 is located above the grinding disc 25. The connecting rod 27 rotates through the middle of the conical disc 29, and a first opening 2901 is provided on the conical disc 29. The second rotating disc 30 is connected to the connecting rod 27, and two second openings 3001 are symmetrically provided on the second rotating disc 30. An annular airbag 31 is installed on the lower inner wall of the feeding cylinder 22. The annular airbag 31 is located outside the grinding disc 25, and a gap is left between the annular airbag 31 and the grinding disc 25. The annular airbag 31 needs to be connected to an external air pump when working.

[0035] Initially, the weight sensor 21 is at zero. During the raw material feeding process, solid raw materials are first placed into the loading cylinder 22, where they accumulate on the conical disk 29. At this time, the weight sensor 21 monitors the total weight of the solid raw materials in the loading cylinder 22 in real time. Subsequently, liquid raw materials are placed into the tank 1, and the required amount of solid raw materials is set in the controller 2 according to the liquid-solid ratio. After the setting is completed, the controller 2 starts the second motor 24, which drives the grinding disc 25, connecting rod 27, stirring frame 28, and second rotating disk 30 to rotate synchronously. During the rotation, the stirring frame 28 stirs the loading cylinder. The solid raw materials in 22 are continuously stirred and dispersed to prevent them from clumping. As the second rotating disk 30 rotates, when the second opening 3001 rotates to align with the first opening 2901, the solid raw materials on the conical disk 29 fall down through the first opening 2901 and the second opening 3001 to the top of the grinding disk 25. When the second opening 3001 and the first opening 2901 are misaligned, the feeding stops, thereby realizing intermittent quantitative feeding of solid raw materials. The raw materials falling into the top of the grinding disk 25 move towards the edge under the action of centrifugal force. The grinding disk 25 and the grinding strip 26 rotate relative to each other to grind and crush the raw materials. The ground powder slides down the conical surface of the grinding disc 25, passes through the gap between the conical disc 29 and the annular air bladder 31, enters the hollow slide block 20, and finally falls into the tank 1. The weight sensor 21 monitors the reduction of solid raw material in the feeding cylinder 22 in real time. When the total amount of raw material falling into the tank 1 reaches the preset feeding amount, the weight sensor 21 sends a signal to the controller 2. The controller 2 immediately starts the external air pump to inflate the annular air bladder 31, causing it to expand and seal the gap between the conical disc 29 and the annular air bladder 31, thus blocking the original material. The material continues to fall; it should be noted that when the solid raw material has passed through the above gap but has not yet completely fallen into the tank 1, this part of the raw material is in a suspended state and has left the monitoring range of the weight sensor 21. After the annular airbag 31 expands and blocks the gap, this part of the raw material can still continue to pass through the hollow slide 20 and enter the tank 1, thereby ensuring that the actual feeding amount is highly consistent with the preset value, achieving precise feeding. The whole process does not require manual intervention, and the intermittent feeding method helps the raw material to remain dispersed before entering the tank 1, promoting uniform mixing in the later stage.

[0036] like Figure 10 As shown, it also includes an annular air pipe 32. The annular air pipe 32 is connected to the lower side of the inner wall of the feeding cylinder 22, and the annular air pipe 32 is located below the annular air bag 31. When working, the annular air pipe 32 needs to be connected to an external air pump. Air is blown downward through the annular air pipe 32 to generate an auxiliary airflow, which pushes the solid raw material into and through the hollow slide block 20 quickly, preventing the raw material from being stuck in the hollow slide block 20.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
