Description

Technical Field

[0001] The invention relates to the technical field of flow control, and in particular to a rectangular distributor outlet flow control structure and method. Background Art

[0002] With the rapid advancement of the resource utilization of livestock and poultry manure, the supporting rate of manure treatment facilities in large-scale farms has increased year by year. The efficient transportation and uniform distribution of liquid fertilizers are crucial to the growth of crops. Traditional liquid fertilizer distribution systems often have the problem of uneven flow between fertilizer pipes. Especially in the case of multiple pipeline outlets, liquid fertilizer is easily concentrated in a few outlets, resulting in excessive liquid fertilizer in some local areas and insufficient supply in other areas. This not only affects the utilization rate of fertilizers, but may also cause crop root burns or fertilizer waste. How to solve the resource utilization of manure has become a problem that needs to be solved urgently.

[0003] At present, organic liquid fertilizer is transported to the distributor housing through the fertilizer inlet pipe, and the internal pressure difference of the device enables the liquid fertilizer to be spread to the field through the fertilizer outlet pipeline. Due to the simple structure of the rectangular shell, it is impossible to ensure that the liquid fertilizer flow in each fertilizer outlet pipeline is even, and there are problems such as unstable pressure, uneven flow, and low efficiency in multi-way distribution; In addition, most of the existing technologies improve the distribution efficiency by improving the liquid fertilizer distribution structure and regulation methods, but these methods usually lack the ability to accurately control the liquid fertilizer flow rate, and it is difficult to achieve flow balance and activity regulation between multiple fertilizer outlet pipes. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a rectangular distributor outlet flow control structure and method.

[0005] A rectangular distributor outlet flow control structure, the structure comprising: Distributor housing; A fertilizer inlet pipe is installed on one side of the distributor housing; A plurality of fertilizer outlet pipes are arranged on the side wall of the distributor housing and are opposite to the fertilizer inlet pipes; a drive motor mounted on a side wall of the distributor housing, with a drive shaft extending to the other side of the distributor housing; Four auger blades are arranged on the side wall of the output shaft of the driving motor.

[0006] Furthermore, the adjacent auger blades have opposite rotation directions, and the auger blades are arranged equidistantly.

[0007] A rectangular distributor outlet flow control method, the method is based on any rectangular distributor outlet flow control structure, the method comprising: According to the location of the fertilizer delivery pipeline, the fertilizer delivery pipeline is divided into fertilizer delivery areas; Obtain flow data of each fertilizer output area and flow value of the fertilizer input pipeline, wherein the flow data includes regional flow data of each fertilizer output area at time t and regional flow change value of each fertilizer output area from time t to time t+k, and compare the flow data of each fertilizer output area, generate comparison data and output; The auger is adjusted according to the comparison data and the preset fertilizer output target, and the flow adjustment is verified according to the regional flow change value of each fertilizer output area, and the verification result is output.

[0008] Furthermore, the fertilizer output area includes area A, area B, area C, area D and area E, and the number of fertilizer output pipelines arranged in a single fertilizer output area is greater than or equal to 1.

[0009] Furthermore, the regional flow data includes a fertilizer flow value Vr of region A, a fertilizer flow value Vs of region B, a fertilizer flow value Vt of region C, a fertilizer flow value Vx of region D, and a fertilizer flow value Vy of region E. Assuming that the flow value of the fertilizer inlet pipeline is V, the logical relationship between the flow value of the fertilizer inlet pipeline V and the flow data of each region is: V=Vr+Vs+Vt+Vx+Vy.

[0010] Further, the regional flow change value includes a fertilizer flow change value of region A, a fertilizer flow change value of region B, a fertilizer flow change value of region C, a fertilizer flow change value of region D, and a fertilizer flow change value of region E.

[0011] Furthermore, the logic for comparing the flow data of each fertilizer distribution area is as follows: The sum of the fertilizer flow value Vr of area A, the fertilizer flow value Vt of area C and the fertilizer flow value Vy of area E is multiplied by two, and divided by three times the sum of the fertilizer flow value Vs of area B and the fertilizer flow value Vx of area D minus 1, to obtain the fertilizer comparison value Dv=2 / (3(Vs+Vx))×(Vr+Vt+Vy)-1, A first threshold k1 and a second threshold k2 are set, wherein k1<0<k2, and the fertilizer comparison value Dv is compared with the first threshold k1 and the second threshold k2 to generate comparison data.

[0012] Furthermore, the comparison data includes an ACE three-region high flow mark, a BD two-region high flow mark, and a flow stability mark. The generation logic of the comparison data is: Substitute the fertilizer output comparison value Dv into the first threshold k1 and the second threshold k2, where the threshold k1 is less than the second threshold k2. If the fertilizer output comparison value Dv is greater than or equal to the second threshold k2, an ACE three-region high flow mark is generated; if the fertilizer output comparison value Dv is less than or equal to the first threshold k1, a BD two-region high flow mark is generated; if the fertilizer output comparison value Dv is greater than the first threshold k1 and greater than the second threshold k2, a flow stability mark is generated.

[0013] Furthermore, the logic of adjusting the auger according to the comparison data is: Setting fertilizer output targets, the fertilizer output targets include converting high flow in three ACE areas into high flow in two BD areas, converting high flow in three ACE areas into equal flow in five areas, converting high flow in two BD areas into high flow in three ACE areas, and converting high flow in two BD areas into equal flow in five areas; Based on the comparison data generated at time t, if the fertilizer output target is to convert the high flow rate of the three-area ACE into the high flow rate of the two-area BD, or to convert the high flow rate of the three-area ACE into the equal flow rate of the five-area ACE, the drive motor is positively regulated, and the positive regulation is that the drive motor drives the infusion direction of the auger blade to change from biased towards area A, area C and area E to biased towards area B and area D; If the fertilizer output target is to convert the high flow rate of the BD double areas into the high flow rate of the ACE three areas, or to convert the high flow rate of the BD double areas into the equal flow rate of the five areas, the drive motor is negatively regulated, and the negative regulation is that the drive motor drives the infusion direction of the auger blades to change from being biased towards areas B and D to being biased towards areas A, C and E.

[0014] Furthermore, the logic of flow regulation verification based on the regional flow change value of each fertilizer output area is: The regional flow change value of each fertilizer-distributing area from time t to time t+k is compared with the preset fertilizer-distributing target. If the flow change of a single area does not match the preset fertilizer-distributing target, an abnormal flow control label is generated and the auger adjustment is repeated. If the flow change of a single area matches the preset fertilizer-distributing target, a normal flow control label is generated.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting the blade rotation directions of adjacent auger blades to be opposite, pressure balance can be achieved during the liquid fertilizer distribution process, avoiding excessive or insufficient pressure in a single fertilizer outlet pipeline, thereby ensuring uniform liquid fertilizer flow in each fertilizer outlet pipeline and improving the liquid fertilizer delivery efficiency. In addition, the design of the auger blades can also effectively mix the solids and liquids in the liquid fertilizer and crush the solid matter, further reducing pipeline resistance, reducing the risk of blockage, and improving the overall operating stability and efficiency of the distributor.

[0016] Through real-time comparison of regional division and flow data, precise adjustment of liquid fertilizer flow can be achieved to ensure that the liquid fertilizer distribution in different areas meets the preset goals. Combined with the positive or negative regulation of the drive motor based on the comparison data, the problem of flow differences between regions can be effectively solved, ensuring flow stability and realizing flexible regulation of liquid fertilizer flow when discharging fertilizer from the fertilizer delivery pipeline.

Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

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.

[0019] Example 1 See also Figure 1 As shown, this embodiment discloses a rectangular distributor outlet flow control structure, the structure comprising: Distributor housing; A fertilizer inlet pipe is installed on one side of the distributor housing; A plurality of fertilizer outlet pipes are arranged on the side wall of the distributor housing and are arranged opposite to the fertilizer inlet pipes; a drive motor mounted on a side wall of the distributor housing, with a drive shaft extending to the other side of the distributor housing; The auger blade is arranged on the side wall of the output shaft of the driving motor.

[0020] Specifically, the auger blades are provided with four leaves, the adjacent auger blades have opposite rotation directions, and the auger blades are arranged equidistantly.

[0021] It should be noted that: the driving motor is a servo motor; See also Figure 2 It can be seen that the adjacent auger blades have opposite rotation directions, and during the rotation of the auger blades, Figure 2 The liquid fertilizer at the end of the fertilizer outlet pipe with a larger liquid outlet pressure is transported to the end of the fertilizer outlet pipe with a smaller liquid outlet pressure, thereby achieving a pressure balancing effect on each fertilizer outlet pipe, so as to achieve a uniform liquid fertilizer flow rate in each fertilizer outlet pipe. In addition, the setting of the auger blades in this embodiment can mix the solid and liquid in the liquid fertilizer and crush the solid matter, thereby reducing the resistance of the liquid fertilizer in the pipeline, avoiding blockage in the pipe of the distributor shell, and thus improving the transportation efficiency of the liquid fertilizer.

[0022] Example 2 See also Figure 2 and Figure 3 As shown, this embodiment discloses a method for controlling flow rate at an outlet of a rectangular distributor, the method comprising: S110: dividing the fertilizer delivery pipeline into fertilizer delivery areas according to the location of the fertilizer delivery pipeline; Specifically, the fertilizer output area includes area A, area B, area C, area D and area E, and the number of fertilizer output pipelines arranged in a single fertilizer output area is greater than or equal to 1; It should be noted that: the setting area of ​​the fertilizer outlet pipe is the area where the fertilizer outlet pipe is installed on the side wall of the dispenser housing; The areas where the multiple fertilizer outlet pipes are located are divided into area A, area B, area C, area D and area E. In combination with the setting of the blade rotation directions of the adjacent auger blades in embodiment 1 being opposite, the liquid fertilizer in the fertilizer outlet pipes in the areas with larger liquid fertilizer flow (area A, area C and area E) can be transported to the fertilizer outlet pipes in the areas with smaller liquid fertilizer flow (area B and area D); S120: Obtaining flow data of each fertilizer delivery area and flow value of the fertilizer inlet pipeline, wherein the flow data includes regional flow data of each fertilizer delivery area at time t and regional flow change value of each fertilizer delivery area from time t to time t+k, and performing data comparison on the flow data of each fertilizer delivery area, generating and outputting comparison data; Specifically, the regional flow data includes the fertilizer flow value Vr of region A, the fertilizer flow value Vs of region B, the fertilizer flow value Vt of region C, the fertilizer flow value Vx of region D and the fertilizer flow value Vy of region E. Assuming the flow value of the fertilizer inlet pipeline is V, the logical relationship between the flow value of the fertilizer inlet pipeline V and the flow data of each region is: V=Vr+Vs+Vt+Vx+Vy; Specifically, the regional flow change value includes the fertilizer flow change value of region A, the fertilizer flow change value of region B, the fertilizer flow change value of region C, the fertilizer flow change value of region D and the fertilizer flow change value of region E; It should be noted that the flow data of each fertilizer outlet area and the flow value of the fertilizer inlet pipeline are collected by a flow meter.

[0023] Specifically, the logic for comparing the flow data of each fertilizer distribution area is as follows: The fertilizer comparison value is obtained by multiplying the sum of the values ​​of the fertilizer flow value Vr of area A, the fertilizer flow value Vt of area C, and the fertilizer flow value Vy of area E by two, and dividing it by three times the sum of the values ​​of the fertilizer flow value Vs of area B and the fertilizer flow value Vx of area D minus 1. , Set a first threshold k1 and a second threshold k2, wherein k1<0<k2, and compare the fertilizer comparison value Dv with the first threshold k1 and the second threshold k2 to generate comparison data; Specifically, the comparison data includes an ACE three-region high flow mark, a BD two-region high flow mark, and a flow stability mark. The generation logic of the comparison data is: Substitute the fertilizer output comparison value Dv into the first threshold value k1 and the second threshold value k2, where the threshold value k1 is less than the second threshold value k2. If the fertilizer output comparison value Dv is greater than or equal to the second threshold value k2, an ACE three-region high flow mark is generated; if the fertilizer output comparison value Dv is less than or equal to the first threshold value k1, a BD two-region high flow mark is generated; if the fertilizer output comparison value Dv is greater than the first threshold value k1 and greater than the second threshold value k2, a flow stability mark is generated; It should be noted that the high flow mark of the three ACE zones indicates that the liquid fertilizer flow rate of the fertilizer pipes in the three zones A, C and E is large, and the fertilizer output rate is fast. At this time, the liquid fertilizer flow rate of the two BD zones is small, and the fertilizer output rate is slow. The high flow mark of the BD double area indicates that the liquid fertilizer flow rate of the fertilizer pipes in the double areas of area B and area D is large, and the fertilizer output rate is fast. At this time, the liquid fertilizer flow rate of the three areas of ACE is small, and the fertilizer output rate is slow; and the stable flow mark indicates that the difference in liquid fertilizer flow rate of area A, area B, area C, area D and area E is small, and the liquid fertilizer flow rate of the fertilizer pipes in the five areas is almost the same or exactly the same; S130: adjusting the auger according to the comparison data and the preset fertilizer output target, and verifying the flow adjustment according to the regional flow change value of each fertilizer output area, and outputting the verification result; Specifically, the logic of adjusting the auger according to the comparison data is: Setting fertilizer output targets, the fertilizer output targets include converting high flow in three ACE areas into high flow in two BD areas, converting high flow in three ACE areas into equal flow in five areas, converting high flow in two BD areas into high flow in three ACE areas, and converting high flow in two BD areas into equal flow in five areas; It should be noted that the marks corresponding to ACE three-area high flow, BD two-area high flow and five-area equal flow are ACE three-area high flow mark, BD two-area high flow mark and stable flow mark respectively; Based on the comparison data generated at time t, if the fertilizer output target is to convert the high flow rate of the three-area ACE into the high flow rate of the two-area BD, or to convert the high flow rate of the three-area ACE into the equal flow rate of the five-area ACE, the drive motor is positively regulated, and the positive regulation is that the drive motor drives the infusion direction of the auger blade to change from biased towards area A, area C and area E to biased towards area B and area D; If the fertilizer output target is to convert the high flow rate of the BD double areas into the high flow rate of the ACE three areas, or to convert the high flow rate of the BD double areas into the equal flow rate of the five areas, the drive motor is negatively regulated, and the negative regulation is that the drive motor drives the infusion direction of the auger blades to change from being biased towards areas B and D to being biased towards areas A, C and E.

[0024] Take an example to explain the adjustment of the auger: if the fertilizer output target is to convert the high flow rate of the three-zone ACE into the high flow rate of the two-zone BD, the drive motor is positively regulated until the BD two-zone high flow mark is generated at the T+R moment and stops. If the flow rate of the area B and area D needs to be further expanded, it can be regulated according to the number of BD two-zone high flow marks generated after the T+R moment; Specifically, the logic of flow regulation verification based on the regional flow change value of each fertilizer output area is: According to the regional flow change value of each fertilizer distribution area from time t to time t+k, the preset fertilizer distribution target is compared. If the flow change of a single area does not match the preset fertilizer distribution target, a flow control abnormal label is generated and the auger adjustment is repeated. If the flow change of a single area matches the preset fertilizer distribution target, a flow control normal label is generated. It should be noted that when the flow change of a single fertilizer delivery pipeline in a single area does not match the preset fertilizer delivery target, a flow control anomaly label is generated for the area.
