Description

Technical Field

[0001] This application relates to the technical field of agricultural machinery and equipment, and particularly to a horizontal turbine type precision fertilizer discharging device. Background Art

[0002] The integrated water and fertilizer technology is one of the important means for the transformation of modern agriculture towards precision agriculture and intelligent agriculture. This technology combines irrigation and fertilization, and through scientific and reasonable means, realizes the coordinated utilization of water and fertilizer. While providing sufficient water to crops, it ensures that crops obtain appropriate nutrients through precise fertilization. The integrated water and fertilizer system realizes the integrated management of water and fertilizer, can effectively reduce the waste of water and fertilizer resources, improve crop yield and quality, and improve environmental pollution.

[0003] In an intelligent irrigation system, the growth of crops requires precise regulation of the supply of water and nutrients, and it is particularly crucial to configure a certain concentration of fertilizer solution. By precisely mixing fertilizer with water to form a uniform water and fertilizer solution, and using a pipeline system to transport it to the root area of crops, it ensures that crops can obtain sufficient and appropriate water and nutrients. However, currently, the configuration process of the water and fertilizer solution mostly relies on manual operation. Operators need to manually pour bagged solid fertilizer into the water and fertilizer integration machine, and then add a certain amount of water and stir. Due to the frequent caking phenomenon in solid fertilizer, the dissolution efficiency of fertilizer during the stirring process is low, resulting in an unsatisfactory water and fertilizer mixing effect, and it is difficult to meet the precise requirements of crop growth for the concentration of the fertilizer solution. In addition, different types of crops have different requirements for the concentration of water and fertilizer at each growth stage, which forces operators to frequently adjust the fertilizer solution ratio and configure multiple different concentrations of fertilizer solutions, increasing the labor intensity and operation complexity. When adding solid fertilizer, it is difficult to precisely control the feeding amount, and often it is impossible to achieve precise fertilizer injection, thereby affecting the fertilization efficiency and effect. Most commonly used fertilizer adding devices currently require operators to weigh and proportion the fertilizer in advance and then manually put it into the device. The entire process is complicated and time-consuming, and during the fertilization process, staff also need to continuously monitor the operation status of the equipment. When the set fertilization amount is reached, the pump body needs to be manually stopped. Existing fertilizer adding devices have inaccurate fertilizer injection, high operation complexity, and low efficiency in actual application. They not only increase the operation complexity but also limit the automation level of the system, and it is difficult to achieve efficient and precise quantitative fertilization.

[0033] Embodiment 1:

[0034] As Figures 1 to 5 shown, a horizontal turbine type precise fertilizer discharging device includes:

[0035] A housing 1; the housing is integrally in a cylindrical structure, and a fertilizer inlet 2 is constructed at the top of the housing 1; a rotating shaft 3, a breaking arch knife 301 and a crushing tool 302 are arranged at the top of the rotating shaft 3, and the crushing tool 302 is arranged below the breaking arch knife 301; a fertilizer discharging turbine 4, the fertilizer discharging turbine 4 includes turbine blades 401, a turbine blade mounting seat 402, a fertilizer discharging turbine positioning mounting hole 403, the turbine blades 401 are connected and arranged on the turbine blade mounting seat 402, and the fertilizer discharging turbine positioning mounting hole 403 is constructed at the center of the turbine blade mounting seat 402; a fertilizer discharging turbine base 5, a fertilizer discharging turbine base positioning mounting hole 501 and a fertilizer discharging port 502 are constructed at the bottom of the fertilizer discharging turbine base 5; and a base 6; a motor is connected and arranged inside the base 6.

[0036] Wherein, the fertilizer discharging turbine base 5 is connected and arranged on the base 6, the motor passes through the fertilizer discharging turbine base positioning mounting hole 501 and is connected to the rotating shaft 3, and the rotating shaft 3 is embedded in the fertilizer discharging turbine positioning mounting hole 403.

[0037] Optionally, the housing 1 is integrally in a cylindrical structure, and the diameter of the bottom cylinder is variably set.

[0038] Optionally, the arch-breaking knife 301 is obliquely arranged on the upper part of the rotating shaft 3, and its blades are evenly spaced at an angle of 180°.

[0039] Optionally, the crushing tool 302 is arranged in the middle of the rotating shaft 3, and its blades are evenly spaced at an angle of 120°.

[0040] Optionally, the turbine blades 401 of the fertilizer discharge turbine 4 are arranged in a plurality of pieces, and the turbine blades 401 are evenly distributed around the periphery of the turbine blade mounting seat 402, and the interval between adjacent blades is 72°.

[0041] Optionally, the turbine blade 401 is tilted on the turbine blade mounting seat 402 .

[0042] The device can ensure the continuity of fertilizer supply and the high efficiency of the crushing process by providing the arch-breaking knife 301 and the crushing knife 302, and improve the weighing accuracy and dissolution efficiency of the fertilizer. The fertilizer particles are thrusted by the rotation of the fertilizer discharge turbine 4 to move along a predetermined trajectory. Under the driving action of the fertilizer discharge turbine 4, the fertilizer reaches the fertilizer discharge port and is discharged from the device in an orderly manner to achieve quantitative weighing and accurate delivery of the fertilizer.

[0043] Embodiment 2:

[0044] like Figures 1 to 5 A horizontal turbine type precision fertilizer discharge device is shown, comprising: an outer shell, a rotating shaft, and a fertilizer discharge turbine. The outer shell 1 is an overall cylindrical structure, with a fertilizer inlet 2 provided on the top and fixedly mounted on a fertilizer discharge turbine base 5 at the bottom. A rotating shaft 3 is provided at the center of the inner part of the outer shell 1; an arch breaking knife 301 and a crushing knife 302 are layered on the rotating shaft 3, and are transmission-connected to the fertilizer discharge turbine 4 through a rotating shaft base 303; the fertilizer discharge turbine base 5 is an annular structure, a square fertilizer discharge port 502 is provided on the inner ring, and a fertilizer discharge turbine base positioning mounting hole 501 used for rotating shaft connection is provided at the center.

[0045] The housing 1 of the present application is cylindrical in structure as a whole, specifically, the middle and upper part is cylindrical, and the middle and lower part is variable in diameter, similar to a trapezoidal cylinder, and the bottom gradually converges toward the fertilizer turbine base 5, which cannot effectively accommodate the arch-breaking knife 301 and the crushing knife 302 set on the rotating shaft 3. The housing 1 provides a closed working environment during the operation of the device to prevent the dust or uncrushed particles generated when the fertilizer is crushed from leaking out, ensuring the safety and efficiency of the crushing process. A fertilizer inlet 2 is provided on the top of the housing, which is connected to the external fertilizer feeding pipe and is used to introduce fertilizer into the housing 1. The bottom of the housing 1 is fixedly installed on the fertilizer turbine base 5.

[0046] The rotating shaft 3 is provided with an arch-breaking knife 301 and a crushing knife 302 in layers, and the two cooperate with each other to ensure the continuity of fertilizer supply and the efficiency of the crushing process. The arch-breaking knife 301 is arranged at the upper part of the rotating shaft, and its blades are evenly spaced at an angle of 180° to prevent the solid fertilizer from forming an arch during the feeding process and blocking the upper part of the shell. Through the rotation of the arch-breaking knife 301, the fertilizer can smoothly pass through the fertilizer inlet 2 and enter the crushing area, thereby maintaining the smoothness and continuity of the feeding process; the crushing knife 302 is arranged in the middle of the rotating shaft, and its blades are evenly spaced at an angle of 120° to form a reasonable cutting and crushing path. The rotating crushing knife 302 can effectively crush the agglomerated granular fertilizer into fine granular fertilizer, further improve the weighing accuracy and dissolution efficiency of the fertilizer, help the uniform mixing of the fertilizer liquid, and ensure the smooth progress of the subsequent water-fertilizer mixing process. The rotating shaft 3 is connected to the fertilizer discharge turbine 4 through transmission, and moves coaxially through a stepping motor arranged at the bottom of the rotating shaft 3. The rotation of the motor drives the rotating shaft 3 and the fertilizer discharge turbine 4 to rotate synchronously, thereby realizing the precise fertilizer discharge process of the fertilizing device.

[0047] The fertilizer turbine 4 is a multi-blade structure, and the blades are evenly distributed around the outer periphery of the turbine, and the interval between adjacent blades is 72°. The center of the turbine is provided with a fertilizer turbine positioning and mounting hole 403 for connecting the rotating shaft 3. Through this hole, it is tightly connected to the rotating shaft 3 to ensure that the fertilizer turbine 4 can rotate synchronously and stably under the drive of the rotating shaft 3. After the fertilizer falls to the fertilizer turbine base 5 through the fertilizer inlet 2, the fertilizer turbine 4 will comb the scattered fertilizer evenly, and rely on the rotation of the fertilizer turbine 4 to apply thrust to the fertilizer particles to make them move along a predetermined trajectory, which can effectively prevent fertilizer accumulation or blockage. With the cooperation of the square fertilizer outlet 502 of the fertilizer turbine base 5, the fertilizer is gradually and orderly discharged from the device under the driving action of the fertilizer turbine 4, thereby ensuring the continuity and uniformity of the entire fertilizer discharge process.

[0048] In this application, the breaking arch knives 301 and crushing cutters 302 are arranged in layers on the rotating shaft 3. The two cooperate with each other to ensure the continuity of fertilizer supply and the efficiency of the crushing process. In the actual use of this device, the rotation speed of the rotating shaft 3 is one of the key factors affecting the entire fertilizer discharging process. If the rotation speed of the rotating shaft 3 is too fast, the high-speed rotation of the breaking arch knives 301 and crushing cutters 302 may cause an occlusion effect on the falling fertilizer, thereby inhibiting the smooth falling of some fertilizers, and further affecting the overall fertilizer discharging efficiency. On the other hand, if the rotation speed of the rotating shaft 3 is too slow, the rotation speed of the breaking arch knives 301 and crushing cutters 302 is insufficient, and it is difficult to effectively break up the caked granular fertilizer, resulting in the fertilizer not being fully crushed into fine particles, which will have an adverse impact on the fertilizer discharging accuracy and dissolution efficiency, and further affect the uniform mixing of the fertilizer solution. Therefore, when in use, the rotation speed of the rotating shaft 3 needs to be precisely controlled according to the actual fluidity of the fertilizer, particle size, and required crushing accuracy. By reasonably adjusting the rotation speed of the rotating shaft 3, not only can the smooth falling of the fertilizer be ensured, but also efficient crushing can be achieved, thereby improving the discharging and dissolution effects of the fertilizer.

[0049] In this application, the fertilizer discharging turbine 4 is designed with a multi-blade structure, and the blades are evenly distributed around the outer circumference of the turbine. The fertilizer discharging turbine 4, as the core component for realizing precise fertilizer discharging, its design and operation play a crucial role in the fertilizer discharging efficiency of the entire device. Relying on the rotation of the fertilizer discharging turbine 4 to apply a thrust to the fertilizer particles to make them move along a predetermined trajectory, the fertilizer is gradually and orderly discharged from the device under the pushing action of the fertilizer discharging turbine. The rotation speed of the fertilizer discharging turbine 4 is one of the key parameters affecting the fertilizer discharging efficiency. If the rotation speed of the turbine is too fast, the rotating blades may form an obstructive effect on the falling fertilizer, resulting in some fertilizers not being able to enter the fertilizer discharging channel in time, thereby affecting the overall fertilizer discharging efficiency and uniformity. On the contrary, if the rotation speed of the turbine is too slow, the driving force of the turbine on the fertilizer is insufficient, and the movement speed of the fertilizer in the device slows down, resulting in an extended time for it to reach the fertilizer discharging port, thereby reducing the fertilizer discharging efficiency. Therefore, the rotation speed of the fertilizer discharging turbine 4 should be finely adjusted according to the physical properties of the fertilizer particles, the required fertilizer discharging speed, and discharging accuracy to ensure that the fertilizer realizes efficient and precise quantitative discharging under an appropriate thrust.

[0050] This application provides a specific control method for control, that is, to establish a mathematical model of the discharging time and the fertilizer discharging amount, and indirectly reflect the fertilizer discharge amount through the running time of the device. The rotation speed of the fertilizer discharging turbine 4 will affect the fertilizer discharge, and further affect the accuracy of predicting the fertilizer discharge amount through time. In order to verify the working performance of the device at different rotation speeds, this device has carried out simulation tests under the conditions that the rotation speed of the fertilizer discharging turbine is 5 rad / s, 10 rad / s, and 20 rad / s respectively. The results show that when the rotation speed of the fertilizer discharging turbine is 5 rad / s, the best linear fitting effect is presented between the fertilizer discharging time and the fertilizer discharging amount, and its linear regression coefficient (R 2)It reaches 0.9992, indicating that the accuracy of predicting the fertilizer application amount by the passing time is the highest at this rotational speed, and the stability of the fertilizer application process is the best.

[0051] Finally, it should also be noted that in this article, relationships such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0052] The unit described as a separate component may or may not be physically separated. The component shown as a unit may or may not be a physical unit, that is, it may be located in one place, or may be distributed to multiple network units. Some or all of the units can be selected according to actual needs to achieve the purpose of the solution of this embodiment.

[0053] Compared with the quantitative fertilizer adding devices on the market, the utility model can realize the quantitative weighing and precise delivery of fertilizers through the designed fertilizer discharging turbine 4. Based on this, the utility model can achieve the precise discharge of fertilizers by adopting a relatively simple control strategy, thereby significantly reducing the complexity and operation and maintenance costs of the quantitative fertilizer adding device, and having higher market promotion and application value.

[0054] The utility model can ensure the continuity of fertilizer supply and the high efficiency of the pulverizing process, and improve the weighing accuracy and dissolution efficiency of fertilizers by setting the arch-breaking knife 301 and the pulverizing tool 302. The rotation of the fertilizer discharging turbine 4 exerts a thrust on the fertilizer particles to make them move along a predetermined trajectory. Under the pushing action of the fertilizer discharging turbine, the fertilizers reach the fertilizer discharging port and are discharged from the device orderly. The utility model is applicable to different types and magnitudes of fertilizers. By designing a corresponding control system, the efficient operation of the measurement and discharging processes can be realized, and the working efficiency in the fertilization process is greatly improved.

[0055] Compared with the commonly used fertilizer adding devices, this device significantly reduces the manual operation links. By integrating an automatic control system, the comprehensive control of the fertilizer adding process can be easily realized, effectively improving the fertilizer adding efficiency, reducing the problem of inaccurate fertilizer application amount caused by operator errors, and ensuring the precise control of the fertilizer solution concentration. The high degree of automation and simplicity of operation of the device make it have higher reliability and stability, and have a wider application scenario in modern agriculture.
