Description

Technical Field

[0001] This invention relates to the technical field of fertilizer raw material processing, and in particular to an automatic fertilizer raw material mixer with precise proportioning. Background Technology

[0002] In modern agricultural production, fertilizers are core materials for increasing crop yields and improving soil fertility. The quality of their processing directly determines the growth effect of crops and the quality of agricultural products. Currently, in the traditional fertilizer mixing process, the raw material ratio and mixing steps generally rely on manual operation. The core process is usually as follows: First, the operator manually weighs various types of raw materials (such as nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, organic fertilizer, and various trace element additives) according to the preset fertilizer formula. After weighing, the raw materials are poured into the mixing tank in sequence by manual handling. The mixing equipment is then started to stir and mix. After the mixture meets the preset requirements, the material is discharged to complete the processing.

[0003] In the traditional model, the two steps of manual weighing and manual feeding are independent of each other. After weighing one raw material, it is necessary to wait for the operator to move the raw material to the mixing tank and complete the feeding before the next raw material can be weighed. There are obvious waiting gaps between the processes, making it impossible to achieve continuous operation of raw material weighing, feeding and mixing. This kind of processing has poor continuity, reduces processing efficiency, and the repetitive operation of manual weighing, moving and feeding is physically demanding.

[0004] Therefore, those skilled in the art have provided an automatic fertilizer raw material mixer with precise proportioning to solve the problems mentioned in the background art.

[0010] Preferably, the stirring mechanism includes a drive motor installed above the mixing tank, a support plate is fixedly connected between the drive motor and the outside of the supporting truncated cone, a stirring shaft is fixedly connected to the output end of the drive motor, and multiple stirring blades are evenly fixedly connected to the stirring shaft from top to bottom.

[0011] Preferably, the inner wall of the mixing tank is circumferentially fixedly connected with multiple fixing rods, and the near ends of the multiple fixing rods are jointly fixedly connected with an annular sleeve, which is sleeved on the outside of the stirring shaft. The stirring shaft is fixedly fitted with limiting rings above and below the annular sleeve.

[0012] Preferably, each of the gravity sensors has a protruding rod fixedly connected to its top, and the top of each protruding rod penetrates the interior of the upper annular support plate.

[0013] Preferably, a plurality of support columns are uniformly fixedly connected to the lower edge of the turntable, and the bottom of each support column is attached to the top of the support frustum.

[0014] Preferably, the inner diameter of the lower annular support plate is larger than the outer diameter of the pre-weighed tank.

[0015] Preferably, each of the T-shaped brackets has two diagonal braces installed on both sides of its bottom in a figure-eight shape.

[0017] In summary, the present invention has the following beneficial technical effects:

[0018] 1. The second servo motor drives the spiral feed rod to rotate, continuously and evenly conveying the raw materials inside the feed slant tube to the pre-weighing tank.

The gravity sensor signals are converted into numerical values ​​by the control terminal and displayed on the control terminal screen, allowing real-time awareness of the weight of the raw materials added to the pre-weighing tank. Simultaneously, the third servo motor drives the adjusting plate to a horizontal position, promptly blocking further material feeding into the transparent feed tube, reducing raw material weighing errors, and improving the accuracy of proportioning. At the same time, the first servo motor drives the turntable, lower annular support plate, and pre-weighing tank to rotate and adjust their positions, enabling continuous weighing of multiple raw materials before direct feeding into the mixing tank for mixing. This device makes the entire process of weighing, feeding, and mixing more seamless, saving time in the processing procedure, improving daily processing efficiency, and reducing the physical exertion of workers during processing.

[0019] 2. By fixing a limiting rod to one side of the bottom of the inner wall of the transparent feeding tube, the limiting rod can limit the adjustment plate, ensuring the consistency of the horizontal state of the adjustment plate after each reset. This allows the adjustment plate to stop the feeding state of the transparent feeding tube in a timely, fast and effective manner after reset, reducing the error value when weighing raw materials and further improving the accuracy of the proportioning.

[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] refer to Figures 1-6As shown, this invention discloses an automatic fertilizer raw material mixer with precise proportioning, including a support base 13. Support feet 14 are installed at the four corners of the support base 13. Multiple support rods 5 are fixed circumferentially at the center of the support base 13. A support frustum 4 is fixedly connected to the tops of the multiple support rods 5. A first servo motor 2 is installed at the center of the support frustum 4. A turntable 1 is fixedly connected to the output end of the first servo motor 2. A connecting plate 20 is fixedly connected to one side of the outer edge of the turntable 1. A control terminal 19 is installed above the connecting plate 20. A lower annular support plate 18 is fixedly connected to one end of the connecting plate 20. A pre-weighing tank 16 passes through the center of the lower annular support plate 18. An upper annular support plate 17 is fixedly fitted above the pre-weighing tank 16. Multiple gravity sensors 30 are evenly installed above the lower annular support plate 18. The tops of the multiple gravity sensors 30 overlap the lower annular support plate 17. Multiple T-shaped brackets 11 are evenly installed around the periphery of the support base 13 with the turntable 1 as the center. Each T-shaped bracket 11 has a crossbar 10 fixedly connected to its top. Each crossbar 10 has a feeding mechanism at its adjacent ends. A mixing tank 15 is installed on one side of the supporting frustum 4 on the support base 13. The mixing tank 15 contains a stirring mechanism. The feeding mechanism includes a sleeve 8 fixedly connected to the end of the crossbar 10. A transparent feeding pipe 9 is fixedly fitted inside the sleeve 8. A second servo motor 6 is installed at the top of the transparent feeding pipe 9. A spiral feeding rod 28 is fixedly connected to the output end of the second servo motor 6. The outer edge of the feed rod 28 is attached to the inner wall of the transparent feed tube 9. An adjustment plate 33 is sleeved at the bottom of the spiral feed rod 28 inside the transparent feed tube 9. A through rod 35 is fixedly inserted inside the adjustment plate 33, and both ends of the through rod 35 pass through the transparent feed tube 9. A fixing plate 31 is fixedly connected below the crossbar 10. A third servo motor 32 is fixedly connected to the bottom of the fixing plate 31, and the output end of the third servo motor 32 is fixed to one end of the through rod 35. An inclined feed tube 7 is installed above the transparent feed tube 9.

[0029] The control terminal 19 can be activated by pressing the button to start the first servo motor 2, which in turn drives the turntable 1 to rotate. The rotating turntable 1, in conjunction with the connecting plate 20, drives the control terminal 19, the lower annular support plate 18, and the pre-weighing tank 16 to rotate, allowing the pre-weighing tank 16 to rotate directly below the corresponding transparent feeding pipe 9. Then, the third servo motor 32 is activated, causing its output to drive the through rod 35 to rotate, causing the adjusting plate 33 to flip vertically inside the transparent feeding pipe 9, preventing obstruction of material flow. Next, the second servo motor 6 is activated, causing its output to drive the spiral feeding rod 28 to rotate, continuously and evenly conveying the raw material from the feed pipe 7 to the pre-weighing tank 16. At this point, the raw material inside the pre-weighing tank 16... The weight is distributed within multiple gravity sensors 30 via the upper annular support plate 17. The gravity signals from the multiple gravity sensors 30 are transmitted to the control terminal 19, which converts the signals into numerical values ​​and displays them on its screen. This allows for real-time and clear monitoring of the weight of the raw materials added to the pre-weighing tank 16. When the specified weight is reached, the control terminal 19 can be quickly reset by pressing the reset button. This controls the third servo motor 32 to drive the adjusting plate 33 to a horizontal position, preventing further material feeding from the transparent feeding pipe 9, reducing weighing errors, and improving the accuracy of the proportioning. Then, the bottom cover of the pre-weighing tank 16 is manually opened, allowing the weighed raw materials to fall directly into the mixing tank 15. The same steps are repeated when weighing the next raw material. After weighing, the raw materials in the pre-weighing tank 16 are fed into the mixing mechanism for mixing.

[0030] refer to Figure 1 and Figure 2 As shown, the stirring mechanism includes a drive motor 22 installed above the mixing tank 15. A support plate 21 is fixedly connected between the drive motor 22 and the outside of the support truncated cone 4. A stirring shaft 25 is fixedly connected to the output end of the drive motor 22. Multiple stirring blades 23 are evenly fixedly connected to the stirring shaft 25 from top to bottom. By starting the drive motor 22, the output end of the drive motor 22 can drive the stirring shaft 25 to rotate, thereby driving the multiple stirring blades 23 to rotate, thus realizing the mixing and stirring of multiple raw materials.

[0031] refer to Figure 2 and Figure 3 As shown, the mixing tank 15 has multiple fixed rods 24 circumferentially fixedly connected to its inner wall. The near ends of the multiple fixed rods 24 are all fixedly connected to an annular sleeve 27, which is sleeved on the outside of the stirring shaft 25. Limiting rings 26 are fixedly fitted on the outside of the stirring shaft 25 above and below the annular sleeve 27. These rings provide lateral support to the stirring shaft 25 without affecting its normal rotation, thus ensuring the stability of the stirring shaft 25 and the multiple fixed rods 24 during the mixing process.

[0032] refer to Figure 1 and Figure 2 As shown, each of the multiple gravity sensors 30 has a protruding rod 29 fixedly connected to its top, and the top of each protruding rod 29 penetrates the interior of the upper annular support plate 17 to limit the pre-weighing tank 16 and prevent the pre-weighing tank 16 from tilting or misaligning, which would affect the error when weighing the raw materials later.

[0033] refer to Figures 1-6 As shown, multiple support columns 3 are uniformly fixedly connected to the lower edge of the turntable 1, and the bottom of each support column 3 is attached to the upper part of the support frustum 4. The multiple support columns 3 can rotate synchronously with the turntable 1 above the support frustum 4, providing real-time support to the lower part of the turntable 1 and ensuring the stability of the turntable 1 driving the pre-weighing tank 16 to rotate.

[0034] refer to Figure 2 and Figure 4 As shown, the inner diameter of the lower annular support plate 18 is larger than the outer diameter of the pre-weighing tank 16, which avoids direct contact between the outside of the pre-weighing tank 16 and the inner circle of the lower annular support plate 18, thus avoiding increased frictional external force and increasing the error when weighing raw materials.

[0035] refer to Figure 1 and Figure 5 As shown, two diagonal braces 12 are installed in a figure-eight shape on both sides of the bottom of each T-shaped bracket 11 to improve the lateral support on both sides of the T-shaped bracket 11 and further ensure the stability of the T-shaped bracket 11 when providing support for the component.

[0036] refer to Figure 5 and Figure 6 As shown, a limiting rod 34 is fixedly connected to one side of the bottom of the inner wall of the transparent feed tube 9. The limiting rod 34 can limit the adjustment plate 33 to ensure the consistency of the horizontal state of the adjustment plate 33 after each reset.

[0037] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] The implementation principle of an automatic fertilizer raw material mixer with precise proportioning according to an embodiment of the present invention is as follows:

[0040] Each feed slant tube 7 has an inclined opening at the top that connects to an external feeding channel. The control buttons for the second servo motor 6, the first servo motor 2, the drive motor 22, and the third servo motor 32 are all integrated on the control terminal 19. When it is necessary to weigh one of the raw materials, the first servo motor 2 can be started by pressing the button on the control terminal 19. This allows the output of the first servo motor 2 to drive the turntable 1 to rotate. Then, the rotating turntable 1, in conjunction with the connecting plate 20, drives the control terminal 19, the lower annular support plate 18, and the pre-weighing tank 16 to rotate. This allows the pre-weighing tank 16 to rotate directly below the corresponding transparent feed tube 9. Then, the third servo motor 32 is started at that location. This allows the output of the third servo motor 32 to drive the through rod 35 to rotate, causing the adjusting plate 33 to flip inside the transparent feed tube 9 to a vertical position, thus avoiding affecting the flow of material inside the transparent feed tube 9.

[0041] Next, by starting the second servo motor 6, the output of the second servo motor 6 can drive the spiral feed rod 28 to rotate, continuously and evenly conveying the raw material inside the feed pipe 7 to the pre-weighing tank 16. At this time, the weight of the raw material inside the pre-weighing tank 16 is distributed in the multiple gravity sensors 30 through the upper annular support plate 17. The gravity signals of the multiple gravity sensors 30 are transmitted to the control terminal 19. The control terminal 19 converts the signals into values ​​and displays them on the display screen of the control terminal 19, so that the weight of the raw material added to the pre-weighing tank 16 can be clearly known in real time. When the weight ratio is reached, the control terminal 19 can quickly reset the third servo motor 32 to drive the adjustment plate 33 to reset to a horizontal state by pressing the reset button, so as to block the continued feeding of material inside the transparent feed pipe 9, reduce the weighing error of the raw material, and improve the accuracy of the ratio.

[0042] Next, the bottom cover of the pre-weighing tank 16 is manually opened so that the weighed raw material can fall directly into the mixing tank 15. The above steps are repeated when weighing the next raw material. After weighing, the raw material in the pre-weighing tank 16 is sent into the mixing tank 15. When using this device, the entire process of weighing, feeding and mixing can be more seamless, saving time in the processing procedure, improving the efficiency of daily processing, and reducing the physical exertion of workers in the processing process.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
