[0002] In the daily disinfection and epidemic prevention work of farms, drug spraying equipment is an important epidemic prevention facility, and its use effect directly affects the effect of disinfection and epidemic prevention. Although the existing fixed spraying system has been widely used, there are still some problems in actual use.

[0003] First, during zone disinfection, different types of livestock and poultry houses often require different disinfection intensities, and operators need to replace different types of nozzles to adjust the flow rate. Secondly, in terms of seasonal adjustment needs, a large flow rate may be required in summer for cooling and disinfection, while a small flow rate is required in winter to avoid freezing. For operators, especially in large farms, the operation is cumbersome and it is difficult to accurately control the flow rate. In addition, in equipment maintenance scenarios, such as cleaning or overhaul, quick-connect structures are used for rapid disassembly and assembly, but some pipeline check mechanisms may fail due to wear or aging, resulting in waste of liquid medicine. Sometimes when technicians need to test the performance of nozzles one by one or perform pipeline pressure tests, they need to repeatedly disassemble and assemble the nozzles, making it difficult to quickly locate faults. Summary of the invention

[0004] In view of the above problems or problems existing in the prior art, the present invention is proposed.

[0005] Therefore, the purpose of the present invention is to provide a drug spraying equipment for treating farm pens, which can solve the problems of frequent replacement of nozzles due to differences in different livestock and poultry houses and seasonal needs, and difficulty in accurately controlling the flow rate; when the equipment is maintained, aging of the pipeline check mechanism can easily cause waste of liquid medicine; at the same time, performance testing and pipeline pressure testing require repeated disassembly and assembly of the nozzle, affecting the efficiency of fault diagnosis.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0023] Example 1 Reference Figure 1~Figure 4 , which is the first embodiment of the present invention, and provides a drug spraying device for treating farm pens, comprising a three-way unit 1, including a three-way pipe 11, a valve core 12 arranged inside the three-way pipe 11, a first spring 13 arranged on the end surface of the valve core 12, a pipe sleeve 14 arranged on the outer wall of the three-way pipe 11, a second spring 15 arranged on the end surface of the pipe sleeve 14, and a plurality of locking balls 16 arranged inside the pipe wall of the three-way pipe 11; The spray unit 2 includes a shell 21 and a spray pipe 22 arranged inside the shell 21 .

[0024] Furthermore, the three-way pipe 11 includes a main pipe 111, a branch pipe 112 arranged on the side wall of the main pipe 111, a prism 113 arranged on the inner wall of the main pipe 111, a valve seat 114 arranged on the inner wall of the branch pipe 112, a plurality of wedge-shaped holes 115 arranged on the inner wall of the branch pipe 112, and a limiting surface 116 arranged on the outer wall of the branch pipe 112.

[0025] Furthermore, the valve core 12 includes an arc-shaped wall 121 disposed at the lower end thereof, and a sealing block 122 disposed at the bottom of the arc-shaped wall 121 .

[0026] Furthermore, the sleeve 14 includes a limiting ring 141 disposed on an end surface thereof.

[0027] Furthermore, the housing 21 includes a snap-fitting groove 211 disposed on an outer wall thereof, a plurality of second injection passages 212 disposed inside a side wall of the housing 21 , and an internal thread 213 disposed on an inner wall of the housing 21 .

[0028] Furthermore, the spray pipe 22 includes a prismatic hole 221 arranged on the top thereof, an external thread 222 arranged on the outer wall of the spray pipe 22, a plurality of strip holes 223 penetrating the side wall of the upper end of the spray pipe 22, a plurality of expansion holes 224 penetrating the side wall of the lower end of the spray pipe 22, and a first injection channel 225 arranged at the bottom of the spray pipe 22.

[0029] Furthermore, the spray pipe 22 is threadedly connected to the housing 21 .

[0030] Furthermore, the prism hole 221 and the prism 113 are consistent in shape, and the two cooperate with each other.

[0031] It should be noted that the three-way pipe 11 is composed of a main pipe 111 and a branch pipe 112. The branch pipe 112 is fixed on the side wall of the main pipe 111. The two are perpendicular to each other and internally connected. The inner walls of the two ends of the main pipe 111 are provided with pipe threads for connecting the pipeline for conveying the medium. Therefore, each three-way unit 1 can be connected in series through a pipeline for conveying and spraying liquid medicine.

[0032] A prism 113 is fixed on the inner wall of the main pipe 111 along the axial direction of the branch pipe 112. The prism 113 extends into the inside of the branch pipe 112. The number of edges of the prism 113 is not limited. In this embodiment, a hexagonal prism is used, and a valve core 12 can be mounted on the outer wall of the prism 113. The through hole in the center of the valve core 12 is also hexagonal, so the valve core 12 can move axially along the prism 113.

[0033] A valve seat 114 is also fixed on the inner wall of the branch pipe 112. The upper surface of the valve seat 114 can fit tightly with the arc-shaped wall 121 at the bottom of the valve core 12. In addition, a through hole for the flow of medium is opened in the valve seat 114, and a sealing block 122 is fixed to the bottom center of the valve core 12 to block the through hole in the center of the valve seat 114, so as to ensure the sealing effect of the valve core 12 on the valve seat 114.

[0034] In addition, a first spring 13 is sleeved between the valve core 12 and the bottom of the prism 113 . Therefore, when no external force is applied, the valve core 12 will always seal the branch pipe 112 under the action of the first spring 13 .

[0035] Inside the side wall of the branch pipe 112 adjacent to the opening, a plurality of wedge-shaped holes 115 are provided radially distributed along the branch pipe 112. The wedge-shaped holes 115 are narrow at both ends and wide in the middle, and can accommodate the locking ball 16 and only allow the locking ball 16 to move in the hole, and a portion of the ball body can be exposed outside the opening of the wedge-shaped hole 115.

[0036] A limiting surface 116 is provided on the outer wall of the branch pipe 112, and the limiting surface 116 faces away from the opening position of the branch pipe 112. A pipe sleeve 14 is also sleeved on the outer wall of the branch pipe 112, and an inwardly buckled limiting ring 141 is fixed to the end surface of the pipe sleeve 14 facing away from the opening direction of the branch pipe 112. The limiting ring 141 is supported by the limiting surface 116 to prevent the pipe sleeve 14 from falling off the outer wall of the branch pipe 112. At the end surface of the limiting ring 141, there is also a second spring 15 sleeved on the outer wall of the branch pipe 112, so that the pipe sleeve 14 can be pushed against the limiting surface 116. It should be noted that in this state, the pipe sleeve 14 can completely wrap and cover the area of ​​the wedge-shaped hole 115, so that each locking ball 16 can only extend into the inside of the branch pipe 112.

[0037] When a person pushes the sleeve 14 in the opposite direction along the force direction of the second spring 15 , the wedge-shaped hole 115 can be exposed to the outside, and each locking ball 16 can move in the wedge-shaped hole 115 .

[0038] Therefore, under normal conditions, the medium flows into the three-way unit 1 through the pipeline and flows to the next pipeline. Due to the sealing of the valve core 12, the medium does not flow out from the branch pipe 112.

[0039] Preferably, the shell 21 is in the shape of a bidirectional through column, with a slightly conical bottom, and an internal thread 213 is provided on the inner wall of the shell 21, and the distance between the head and the tail of the internal thread 213 is relatively short. In addition, a cavity is left at the upper end of the internal thread 213, and a second injection channel 212 leading to the outside is provided on the inner wall of the cavity, and the second injection channel 212 will not be blocked when the shell 21 is sleeved inside the branch pipe 112.

[0040] An annular engaging groove 211 is also provided on the outer wall of the shell 21. When the sleeve 14 is pushed up, the shell 21 is not restricted by the locking ball 16, so that the upper end surface of the shell 21 can enter and support the valve seat 114, and then the sleeve 14 is released. Under the action of the second spring 15, the sleeve 14 is reset and then continues to cover the locking ball 16, so that each locking ball 16 extends to the engaging groove 211. Since the locking ball 16 cannot move at this time, the shell 21 will be effectively connected to the branch pipe 112.

[0041] Preferably, the spray pipe 22 is columnar, and a first injection channel 225 is provided at the center of its lower end portion, and the first injection channel 225 is connected to the inner cavity of the spray pipe 22. In addition, the upper end surface of the spray pipe 22 is sealed, but a prismatic hole 221 is provided, and its shape is consistent with the cross-section of the prism 113, and a large chamfer is made at the opening of the prismatic hole 221. Therefore, after the shell 21 enters the branch pipe 112, the prism 113 can more easily extend into the prismatic hole 221. Therefore, at this time, the spray pipe 22 can only move along the axial direction of the prism 113 and cannot rotate.

[0042] A short distance of external thread 222 is provided on the outer wall of the spray pipe 22, so that the spray pipe 22 can be threadedly matched with the housing 21. When the prism 113 extends into the prism hole 221, the operator can manually rotate the housing 21 and move the spray pipe 22 axially.

[0043] A plurality of through strip holes 223 are provided on the outer wall of the spray pipe 22 adjacent to the prismatic hole 221, and the length of the strip holes 223 is less than the height of the central through hole of the valve seat 114. In addition, a plurality of through expansion holes 224 are provided on the side wall at the lower end of the strip holes 223, and when the expansion holes 224 are covered by the internal threads 213, the expansion holes 224 are not connected to the outside.

[0044] When using, when the operator needs to install the spray unit 2 on the three-way unit 1, the operator pushes the pipe sleeve 14 to expose the wedge-shaped hole 115, and then inserts the pipe sleeve 14 into the branch pipe 112 until the lower end surface of the valve seat 114, and then loosens the pipe sleeve 14 to complete the connection between the two. When disassembling, the reverse operation can be performed. If the valve core 12 is already open, the branch pipe 112 will be automatically blocked.

[0045] It should be noted that the position of the spray pipe 22 in the housing 21 can be preset during operation, so as to control whether the spray pipe 22 directly opens the valve core 12 during the installation of the housing 21 .

[0046] When personnel need to open the valve core 12 or adjust the flow rate, they can twist the shell 21 so that the spray pipe 22 can move axially to lift the valve core 12. When the strip hole 223 is exposed outside the through hole in the center of the valve seat 114, the medicine will enter the inner cavity of the spray pipe 22 and be sprayed out from the first injection channel 225.

[0047] When the housing 21 is further twisted, the portion of the strip hole 223 exposed from the through hole in the center of the valve seat 114 will gradually increase, thereby increasing the flow area and further increasing the flow rate of the liquid medicine.

[0048] Continue to turn the shell 21, and the opening of the strip hole 223 will continue to increase until it reaches the upper limit. When the expansion hole 224 is exposed in the chamber above the internal thread 213, part of the liquid in the inner cavity of the spray tube 22 will be diverted from the expansion holes 224 around it, enter the chamber above the internal thread 213, and finally be sprayed out from the second injection channels 212 around it, which increases the flow rate while also increasing the coverage area of ​​the spray.

[0049] When the valve core 12 needs to be closed, the housing 21 is screwed in the opposite direction until the strip hole 223 is immersed in the through hole at the center of the valve seat 114 .

[0050] In summary, the present invention enables the operator to precisely adjust the flow rate by simply rotating the shell 21, thereby meeting the disinfection intensity requirements of different livestock and poultry houses, and can quickly adapt to seasonal changes in large-flow cooling and disinfection in summer and small-flow antifreeze in winter. In terms of equipment maintenance, combined with the quick-connect structure and the rotation closing function of the spray unit 2, the spray unit 2 can be used directly as a temporary plug, which greatly simplifies the maintenance process. In particular, when the pipeline check mechanism fails due to wear and aging, the closing function of the spray equipment can be used as an emergency backup plan to provide double insurance for the drug spray system. When debugging the system, technicians can use the spray equipment's built-in closing function to complete performance testing and pipeline pressure testing without repeated disassembly and assembly, thereby improving fault diagnosis and maintenance efficiency.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
