Description

Technical Field

[0001] This invention relates to the field of spray technology, and more particularly to a spray immunization device. Background Technology

[0002] When using a vaccine spray to immunize chicks, a quantitative spraying device is used to draw the vaccine liquid from the tank and spray it onto the chicks. The chicks then peck at the vaccine to achieve the immunization effect.

[0003] However, in existing spray immunization equipment, the spray metering device consists of a drive component and a suction cylinder. The drive component drives the piston movement of the suction cylinder to achieve the liquid extraction and drainage operations. However, the amount of liquid extracted and discharged each time is unstable; and because the chicks are transported in chick frames via a belt conveyor mechanism, if the chick frames cannot be removed manually in time after spraying, the chick frames will remain on the belt conveyor mechanism, causing wear and tear. In addition, sudden stops or pauses after spraying can easily cause vaccine droplets on the chick down to slip off, resulting in poor spraying effect.

[0004] Therefore, a spray immunization device is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a spray immunization device that can improve the spraying effect, ensure spraying efficiency, and reduce wear on the belt transmission mechanism.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Spray immunization equipment includes:

[0008] A belt conveyor mechanism for transporting chick crates;

[0009] A buffer tray is provided on the belt transmission mechanism along the extension direction of the belt transmission mechanism. The buffer tray includes a guide portion and a support portion connected to each other. The guide portion is inclined downward relative to the support portion. The end of the guide portion away from the support portion is not higher than the upper end surface of the belt transmission mechanism. The guide portion faces the material feeding direction. The support portion protrudes relative to the upper end surface of the belt transmission mechanism.

[0010] A spray assembly, which is mounted on the belt conveyor mechanism;

[0011] A spray metering mechanism is provided on the belt conveyor mechanism and is connected to the spray assembly. The spray metering mechanism can extract a metered amount of liquid and spray it onto the chicks in the chick frame transported by the belt conveyor mechanism through the spray assembly.

[0012] Furthermore, the belt conveyor mechanism includes a conveyor frame and a conveyor assembly. The conveyor assembly includes a drive motor and a belt conveyor assembly. The drive motor is mounted on the conveyor frame and is connected to the belt conveyor assembly in a driving manner. The belt conveyor assembly is rotatably mounted on the conveyor frame along the extension direction of the conveyor frame. The spray assembly is mounted on the conveyor frame. The support portion extends out from the upper end face of the belt conveyor assembly.

[0013] Furthermore, the belt conveyor assembly includes a drive roller, a driven roller, and a belt. The drive roller and the driven roller are arranged parallel to each other at both ends of the conveyor frame. The drive roller is connected to the drive motor. The belt is sleeved on the drive roller and the driven roller. The support portion protrudes from the upper end face of the belt.

[0014] Furthermore, a support block is provided on the conveying frame, and the buffer tray is disposed on the support block.

[0015] Furthermore, a height adjustment mechanism is provided between the buffer tray and the support block. The height adjustment mechanism can adjust the distance between the buffer tray and the support block, thereby adjusting the protrusion height of the buffer tray relative to the belt transmission assembly.

[0016] Furthermore, the spray metering mechanism includes a mounting plate, a drive assembly, and a suction cylinder. The mounting plate is disposed on the conveying frame, the drive assembly is disposed on the mounting plate, and the suction cylinder includes a cylinder body and a piston. The cylinder body is disposed on the mounting plate, the piston is located in the cylinder body, and one end of the piston extends out relative to the cylinder body. The drive assembly is throttle-connected to the piston, and the drive assembly can drive the piston to move relative to the cylinder body. The cylinder body is in communication with the spray assembly.

[0017] Furthermore, the drive assembly includes a motor and a transmission assembly. The motor is mounted on the mounting plate and is connected in drive to the transmission assembly, which is connected in drive to the piston.

[0018] Furthermore, the spray metering mechanism also includes a positioning component disposed on the mounting plate, the positioning component being used to define the retracted position and the extended position of the piston relative to the cylinder.

[0019] Furthermore, the positioning component includes a first positioning sensor, a second positioning sensor, and a sensing plate. The first positioning sensor and the second positioning sensor are spaced apart on the mounting plate, and the sensing plate is disposed on the piston. The sensing plate can cooperate with the first positioning sensor to limit the position of the piston retracted relative to the cylinder, and the sensing plate can cooperate with the second positioning sensor to limit the position of the piston extended relative to the cylinder.

[0020] Furthermore, the spray assembly includes a mounting bracket and a sprayer. The mounting bracket is mounted on the conveying frame, and the sprayer is mounted on the mounting bracket. The sprayer has multiple spray holes evenly distributed on it, and the spray metering mechanism is connected to the sprayer.

[0021] The beneficial effects of this invention are:

[0022] The present invention provides a spray immunization device, in which a belt conveyor mechanism is used to transport chick frames. A buffer tray is provided on the belt conveyor mechanism along its extension direction. The buffer tray consists of a guide section and a support section. After spraying, the chick frames are guided onto the support section by the belt conveyor mechanism, thereby separating the material from the belt. During this process, the belt conveyor assembly can operate continuously to load and transport the chick frames, ensuring spraying efficiency while reducing belt wear and increasing buffering to prevent vaccine droplets from slipping due to sudden stops or jerks in the chick frames. By setting a spray metering mechanism to work in conjunction with the spray assembly, a metered amount of liquid is sprayed, thereby stabilizing the amount of liquid falling into each chick frame and improving the spraying effect.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the process of spraying vaccines onto chicks, in order to improve the spraying effect, ensure spraying efficiency, and reduce wear on the belt transmission mechanism, such as... Figures 1-4 As shown, the present invention provides a spray immunization device. The spray immunization device includes a belt conveyor mechanism 1, a buffer tray 2, a spray assembly 3, and a spray metering mechanism 4.

[0033] The belt conveyor 1 is used to transport the chicks in the frame. The buffer tray 2 is set on the belt conveyor 1 along the extension direction of the belt conveyor 1. The buffer tray 2 includes a guide part 21 and a support part 22 connected to each other. The guide part 21 is inclined downward relative to the support part 22. The end of the guide part 21 away from the support part 22 is not higher than the upper end face of the belt conveyor 1. The guide part 21 faces the material feeding direction. The support part 22 protrudes relative to the upper end face of the belt conveyor 1. The spray assembly 3 is mounted on the belt conveyor 1. The spray metering mechanism 4 is set on the belt conveyor 1 and is connected to the spray assembly 3. The spray metering mechanism 4 can extract a metered amount of liquid and spray it onto the chicks in the frame transported by the belt conveyor 1 through the spray assembly 3.

[0034] After spraying, the chick frames are guided by the belt conveyor 1 and fed onto the support 22 via the guide 21, thus separating the material from the belt 123. During this process, the belt conveyor 12 can operate continuously to feed and transport the chick frames. The sprayed chick frames are continuously supported on the support 22, which ensures spraying efficiency, reduces wear on the belt 123, and increases buffering to prevent the vaccine droplets from slipping due to sudden stops or jerks in the chick frames. By setting the spray metering mechanism 4 to work in conjunction with the spraying assembly 3, a metered amount of liquid is sprayed, thereby stabilizing the amount of liquid falling into each chick frame and improving the spraying effect.

[0035] Furthermore, the belt conveyor mechanism 1 includes a conveyor frame 11 and a conveyor assembly. The conveyor assembly includes a drive motor and a belt conveyor assembly 12. The drive motor is fixedly mounted on the conveyor frame 11 and is connected to the belt conveyor assembly 12 for transmission. The belt conveyor assembly 12 is rotatably mounted on the conveyor frame 11 along its extension direction. The spray assembly 3 is mounted on the conveyor frame 11, and the support part 22 extends out from the upper end face of the belt conveyor assembly 12. By controlling the rotation of the drive motor, the conveyor assembly is driven to move, and the conveyor assembly drives the chick frame to move, thereby realizing the automation of the chick frame movement and transmission.

[0036] Furthermore, the belt conveyor assembly 12 includes a drive roller 121, a driven roller 122, and a belt 123. The drive roller 121 and the driven roller 122 are arranged parallel to each other at both ends of the conveying frame 11. The drive roller 121 is connected to a drive motor. The belt 123 is sleeved on the drive roller 121 and the driven roller 122, and the support part 22 protrudes from the upper end face of the belt 123. During the conveying of the chick frames, the drive motor drives the drive roller 121, which in turn drives the driven roller 122 to rotate via the belt 123, thereby realizing the movement and conveying of the chick frames by the belt 123. In this embodiment, two sets of belt conveyor assemblies 12 are provided, located on opposite sides of the conveying frame 111.

[0037] Furthermore, a support block 25 is fixedly installed on the conveying frame 11, and the buffer tray 2 is installed on the support block 25. By setting the support block 25, the buffer tray 2 can be effectively supported, and the buffer tray 2 can be easily installed on the conveying frame 11. Specifically, in this embodiment, multiple support blocks 25 are arranged at intervals.

[0038] Furthermore, a height adjustment mechanism is provided between the buffer plate 2 and the support block 25. This mechanism can adjust the distance between the buffer plate 2 and the support block 25, thereby adjusting the protrusion height of the buffer plate 2 relative to the belt transmission assembly 12. By providing this adjustment mechanism, the installation height of the buffer plate 2 can be adjusted according to actual needs, thus flexibly meeting the requirements of different applications. Specifically, the adjustment mechanism includes a screw 24, which is fixedly connected to the support part 22. One end of the screw 24 passes through the support block 25, and a positioning nut 23 is screwed onto the screw 24. By adjusting the position of the nut, the length of the screw 24 inserted into the support block 25 can be adjusted, thereby achieving the purpose of adjusting the height of the support part 22.

[0039] Furthermore, the spray metering mechanism 4 includes a mounting plate 45, a drive assembly 41, and a suction cylinder 42. The mounting plate 45 is mounted on the conveying frame 11, and the drive assembly 41 is mounted on the mounting plate 45. The suction cylinder 42 includes a cylinder 421 and a piston 422. The cylinder 421 is mounted on the mounting plate 45, and the piston 422 is located inside the cylinder 421, with one end of the piston 422 extending relative to the cylinder 421. The drive assembly 41 is connected to the piston 422, and the drive assembly 41 can drive the piston 422 to move relative to the cylinder 421. The cylinder 421 is connected to the spray assembly 3. By setting the mounting plate 45, the installation of the drive assembly 41 and the suction cylinder 42 is facilitated. The piston 422 of the suction cylinder 42 is driven by the drive assembly 41 to achieve the extraction and discharge of liquid.

[0040] Furthermore, the drive assembly 41 includes a motor 411 and a transmission assembly. The motor 411 is fixedly mounted on the mounting plate 45 and is connected to the transmission assembly in a transmission manner. The transmission assembly is connected to the piston 422 in a transmission manner. The motor 411 drives the transmission assembly, thereby driving the piston 422 to move.

[0041] Specifically, in this embodiment, a motor 411 and a lead screw and nut structure are used as the drive component 41. The motor 411 drives the lead screw to rotate, thereby driving the nut to move. The nut and piston 422 are connected through a fisheye connector. By adjusting the forward and reverse rotation of the motor 411, the nut can be raised or lowered, thereby enabling the suction cylinder 42 to pump or discharge liquid. The fisheye connector allows the piston 422 and the nut to float, thereby allowing for minute changes in the up-and-down pushing angle of the piston 422. This avoids abnormal friction between the piston 422 and the cylinder 421, which could cause the cylinder 421 to burst. Secondly, it reduces abnormal friction between the piston 422 and the sealing ring of the cylinder 421, extending the service life of the sealing ring. Thirdly, it prevents slight displacement caused by abnormal friction between the piston 422 and the cylinder 421, and between the piston 422 and the ball screw during long-term operation, which could lead to equipment malfunction.

[0042] Furthermore, the spray metering mechanism 4 also includes a positioning component, which is mounted on the mounting plate 45. The positioning component is used to define the retracted position and extended position of the piston 422 relative to the cylinder 421. By setting the positioning component, the movement position of the piston 422 can be positioned, thereby ensuring that the amount of liquid drawn in and discharged by the suction cylinder 42 is constant, thus ensuring the spraying effect.

[0043] Furthermore, the positioning component includes a first positioning sensor 43, a second positioning sensor 44, and a sensing plate. The first positioning sensor 43 and the second positioning sensor 44 are spaced apart on the mounting plate 45, and the sensing plate is disposed on the piston 422. The sensing plate can cooperate with the first positioning sensor 43 to limit the retracted position of the piston 422 relative to the cylinder 421, and the sensing plate can cooperate with the second positioning sensor 44 to limit the extended position of the piston 422 relative to the cylinder 421. Specifically, both the first positioning sensor 43 and the second positioning sensor 44 are electrically connected to the motor 411. By sensing the position of the sensing plate, the first positioning sensor 43 and the second positioning sensor 44 control the forward and reverse rotation of the motor 411 to achieve automated control of liquid pumping and discharging. In this embodiment, both the first positioning sensor 43 and the second positioning sensor 44 are photoelectric sensors. The first limit sensor or the second limit sensor can determine whether the movement of the piston 422 is in place by sensing the position of the sensing plate. In other embodiments, limit switches or contact sensors can be used instead of photoelectric sensors, and no further restrictions are imposed here.

[0044] Furthermore, the spray assembly 3 includes a mounting bracket 31 and a sprayer. The mounting bracket 31 is mounted on the conveying frame 11, and the sprayer is mounted on the mounting bracket 31. Multiple spray holes are evenly distributed on the sprayer, and the spray metering mechanism 4 is connected to the sprayer. Specifically, in this embodiment, the spray metering mechanism 4 is controlled so that the vaccine solution sprayed in a single pass (30ml) falls in a linear droplet pattern, with 2000-2800 droplets on the film. The spraying time for each frame of chicks is shortened to 3 seconds, the droplet volume is reduced, more droplets adhere to the chick down, and they are less likely to slip off, ensuring the effectiveness of the spray immunization.

[0045] Compared with existing technologies, the number of spray droplets is significantly increased, the droplet size is reduced, the number of droplets adhering to the chickens is increased, and the addition of buffer tray 2 reduces the droplet fall when the spraying of the chicks stops abruptly at the end of the chick frame. Overall, this increases the chances of the chicks pecking at the spray, thereby improving the uniformity of immunization and ensuring the effectiveness of immunization.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
