Description

Technical Field

[0001] The utility model relates to the field of liquid manure distribution, in particular to a rectangular liquid manure distributor with an oblique manure outlet. Background Art

[0002] The function of the rectangular distributor is to transport the organic liquid fertilizer to the rectangular distributor through the fertilizer inlet pipe, and then use the internal pressure difference of the device to ensure that the liquid fertilizer can be evenly spread to the field through the fertilizer outlet pipe. Figure 3 、 Figure 7 As shown, it mainly consists of a fertilizer inlet pipeline, a distributor shell and a fertilizer outlet pipeline.

[0003] At present, when the system distributes liquid fertilizer, the liquid fertilizer enters from the fertilizer inlet and fills the distributor shell. Since the fertilizer outlet pipe and the distributor shell are in vertical contact, the liquid fertilizer will flow to the fertilizer outlet at a certain speed along the positive direction of the Z axis at the connection between the fertilizer outlet pipe and the distributor shell. However, inside the distributor shell, the liquid fertilizer still has a certain speed along the positive and negative directions of the X axis. These liquid fertilizers moving along the positive and negative directions of the X axis will wash away part of the liquid fertilizer that is about to enter the fertilizer outlet pipe, resulting in a reduction in the amount of liquid fertilizer in the fertilizer outlet pipe, and the speed of the liquid fertilizer along the positive and negative directions of the X axis is getting smaller and smaller, causing the liquid fertilizer flow rate at the fertilizer outlet to gradually increase along the positive direction of the X axis. In the area above the contact surface between the fertilizer inlet pipe and the distributor shell, the speed of the liquid fertilizer in the positive direction of the Z axis is much greater than the speed along the X axis, so that the liquid fertilizer in the fertilizer outlet pipe connected to this area can also obtain a larger flow rate. Through the fluid simulation results, it is known that it cannot effectively distribute the liquid fertilizer evenly to each fertilizer outlet pipe, resulting in low uniformity, such as Figure 8 shown.

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions 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 only 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 making creative efforts are within the scope of protection of the present invention.

[0027] Example 1, refer to Figure 1-Figure 5 The top of the rectangular distributor 1 is provided with a plurality of fertilizer pipes 2 and a clamping device. The fertilizer pipe 2 is connected to the rectangular distributor 1. A limit ring 21 is fixedly provided on the fertilizer pipe 2 near the top wall of the rectangular distributor 1. An adjusting device is provided above the limit ring 21. The clamping device is arranged around the limit ring 21. The clamping device is composed of two mounting plates 5 staggered and spliced ​​together. One end of the mounting plate 5 is provided with a clamping block 52, and the other end of the mounting plate 5 is provided with a clamping groove 53 matching the clamping block 52. The clamping block 52 and the clamping groove 53 are correspondingly provided with connecting holes 56. The connecting hole 56 is internally threaded with a connecting bolt 55. The interior of the mounting plate 5 is provided with a slide groove 54 matching the limiting ring 21. The two mounting plates 5 limit the limiting ring 21 by clamping, and the clamping device is fixedly connected to the top of the rectangular distributor 1 through the mounting bolt 51.

[0028] Furthermore, the adjusting device includes a positioning plate 4 and a positioning device 42. The positioning plate 4 is fixedly connected to the outer wall of the fertilizer outlet pipeline 2. The positioning plate 4 rotates synchronously with the fertilizer outlet pipeline 2. When the clamping device limits the limiting ring 21, the bottom wall of the positioning plate 4 is fitted with the top wall of the mounting plate 5. A positioning hole 41 is provided inside the positioning plate 4.

[0029] It should be noted that the positioning device 42 is composed of a wrench and a stud, and the positioning hole 41 is threadedly connected to the stud. The relative position of the stud can be adjusted by turning the wrench, so that the angle between the positioning plate 4 and the fertilizer outlet pipe 2 can be adjusted. The height of the stud is greater than the height of the positioning hole 41, ensuring that the positioning plate 4 can be effectively fixed by the stud. The upper side wall of the mounting plate 5 corresponding to the positioning hole 41 is solid and is provided with anti-slip grooves, ensuring that the stud can be tightly against the upper surface of the mounting plate 5 while also avoiding its accidental sliding.

[0030] In this embodiment, the structural composition is as follows: the clamping device is composed of two mounting plates 5 staggered together, one end of each mounting plate 5 is provided with a clamping block 52, and the other end is provided with a clamping groove 53 matching the clamping block 52. This design allows the two mounting plates 5 to be tightly connected through the mutual engagement of the clamping block 52 and the clamping groove 53. The interior of the mounting plate 5 is provided with a sliding groove 54 matching the limiting ring 21, so that the mounting plate 5 can slide around the limiting ring 21 and fix its position. At the same time, the mounting plate 5 is fixedly connected to the top of the rectangular distributor 1 through the mounting bolt 51 to ensure the stability of the entire clamping device.

[0031] When the two mounting plates 5 limit the limiting ring 21 by snapping together, they together form a stable supporting structure, limiting the movement of the fertilizer outlet pipeline 2 in the vertical direction, and providing a basis for subsequent angle adjustment.

[0032] The adjustment device mainly includes a positioning disk 4 and a positioning device 42. The positioning disk 4 is fixedly connected to the outer wall of the fertilizer discharge pipe 2. Therefore, when the fertilizer discharge pipe 2 needs to be rotated, the positioning disk 4 will also rotate. The positioning device 42 consists of a wrench and a stud. The stud is threadedly connected to the positioning hole 41 inside the positioning disk 4. By turning the wrench, the relative position of the stud in the positioning hole 41 can be adjusted, thereby pushing the positioning disk 4 (and the fertilizer discharge pipe 2 fixed to it) to rotate around its axis to achieve angle adjustment.

[0033] The height of the stud is designed to be greater than the height of the positioning hole 41, ensuring that the stud can be firmly fixed in the positioning hole 41, thereby effectively fixing the angle between the positioning plate 4 and the fertilizer outlet pipe 2. In addition, the upper side wall of the mounting plate 5 corresponding to the positioning hole 41 is solid and provided with anti-slip grooves, which further enhances the friction between the stud and the mounting plate 5 and prevents the stud from accidentally sliding.

[0034] When the angle of the fertilizer discharge pipe 2 needs to be adjusted, first ensure that the clamping device is firmly clamped on the limit ring 21 to provide stable support for the fertilizer discharge pipe 2. Then, by turning the wrench in the positioning device 42, the position of the stud in the positioning hole 41 is adjusted, thereby pushing the positioning plate 4 (and the fertilizer discharge pipe 2) to rotate around its axis to the desired angle.

[0035] Once the desired angle is reached, rotate the wrench in the opposite direction. The height of the stud and the anti-slip grooves on the mounting plate 5 will jointly ensure the stable fixation of the positioning plate 4 and the fertilizer outlet pipe 2, preventing them from accidentally rotating during use.

[0036] This design not only realizes the flexible adjustment of the two angles of the fertilizer discharge pipeline, but also ensures the stability and reliability after adjustment, meeting the needs of different fertilizer discharge angles during the liquid manure distribution process.

[0037] Example 2, refer to Figures 1-9 , multiple groups of fertilizer pipes 2 are symmetrically distributed along the central axis of the rectangular distributor 1, and the angles of the fertilizer pipes 2 can be freely adjusted to ensure that the fertilizer output of each fertilizer pipe 2 is relatively uniform.

[0038] It should be noted that the angle between the fertilizer outlet pipe 2 located in the middle and at both ends of the rectangular distributor 1 and the rectangular distributor 1 is 90 degrees. This is based on the principle of fluid dynamics, which makes the flow distribution at these positions more direct and stable. The angle between the fertilizer outlet pipe 2 located between the middle and both ends of the rectangular distributor 1 and the rectangular distributor 1 is positively correlated with the distance between the fertilizer outlet pipe 2 and the fertilizer inlet pipe 3. That is, the farther away from the fertilizer inlet pipe 3, the larger the angle between the fertilizer outlet pipe 2 and the rectangular distributor 1, so as to compensate for the flow attenuation caused by the distance difference. Figure 9 This is a comparison of the distribution of the fertilizer outlet pipeline 2 between this case and the existing solution.

[0039] In this embodiment, the specific operations are as follows:

[0040] ① According to the required shell size of the rectangular distributor 1 and the required number of fertilizer outlet pipelines 2, the position of the fertilizer outlet pipeline 2 on the shell of the rectangular distributor 1 and the size of the pipeline are determined.

[0041] ②, Based on the fluid simulation software such as Fluent, a rated flow rate is applied to the liquid fertilizer at the fertilizer inlet. The simulation results show that the flow rate of the liquid fertilizer at the fertilizer outlet is not uniform enough (refer to Figure 8 ).

[0042] ③. According to the results obtained in ②, the angle θ of the fertilizer outlet pipeline 2 is adjusted. The inclination angles θ1, θ2, and θ3 of the fertilizer outlet pipeline 2 with a smaller flow rate are reduced. θ1, θ2, and θ3 decrease in sequence. This means that as the distance from the fertilizer inlet increases, the inclination angle of the fertilizer outlet pipeline 2 gradually decreases to compensate for the energy loss of the fluid during the flow process. The result obtained from the simulation again is better than the result in ②, but it is still not the optimal solution.

[0043] ④. Repeat the process in ③ and debug continuously. After each adjustment, re-simulate and further adjust the angle according to the simulation results. This process is iterative until the histograms at the outlet monitoring points tend to be parallel, that is, the flow of each fertilizer outlet tends to be uniform. In this way, the optimal inclination angle of the fertilizer outlet pipeline 2 can be obtained. The closer to the fertilizer inlet, the smaller the angle, so as to achieve the purpose of making the flow of the fertilizer outlet tend to be uniform.

[0044] Through a reasonable layout design of the fertilizer outlet pipeline 2, the uneven flow caused by position differences is reduced; using fluid simulation technology, the angle of the fertilizer outlet pipeline 2 is precisely adjusted to compensate for energy loss and velocity changes in the fluid during the flow process; through a process of continuous iterative simulation and adjustment, the flow distribution of each fertilizer outlet is gradually optimized, and ultimately the flow at the fertilizer outlet is uniform. This not only improves the efficiency and uniformity of liquid manure distribution, but also reduces resource waste and environmental pollution caused by uneven flow.
