Description

Technical Field

[0001] The invention relates to the field of pig farming equipment, and more particularly to a vehicle disinfection device for entering a pig farm. Background Art

[0002] Foreign vehicles need to be disinfected when entering the pig farm to prevent the pathogens on the vehicle from infecting the pigs in the farm and causing swine fever.

[0003] The existing disinfection of vehicles entering the pig farm mainly relies on manpower or simple disinfection equipment. The staff carries a sprayer filled with disinfectant liquid to spray disinfectant on the vehicles entering the farm. Although this method is simple to operate, it also has certain problems, such as the adverse effects of disinfectant on the human body, poor spraying uniformity of disinfectant liquid, spray leakage, and heavy workload of the staff. As for the existing disinfection equipment, it mainly sets multiple nozzles on both sides of the channel, and the nozzles spray when the vehicles pass by. However, this type of disinfection equipment also has certain problems. First, the bottom and top of the vehicles entering the farm cannot be sprayed with disinfectant liquid. Secondly, the spraying uniformity of the disinfectant liquid is not particularly good. Moreover, when spraying disinfectant on the side of the vehicle, due to the different sizes of the vehicles, the distance between the side of the vehicle and the nozzle is different. When the nozzle is far away from the vehicle, most of the disinfectant liquid sprayed by the nozzle will fall due to its own gravity and cannot adhere to the surface of the vehicle, thereby affecting the disinfection effect.

[0004] Therefore, how to provide a pig farm entry vehicle disinfection device that can overcome the above-mentioned problems is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0037] Rack 01;

[0038] Support and limit assembly, the support and limit assembly includes a support rail 02 and a mounting frame 03;

[0039] The support rail 02 is fixed on the frame 01. The support rail 02 is closed at both ends and its center line can define a vertical plane. The center line of the support rail 02 is a rectangle with smooth arcs at four corners. The mounting frame 03 is slidably mounted on the support rail 02. The mounting frame 03 can move along the length direction of the support rail 02.

[0040] A driving assembly, the driving assembly includes a sprocket 06, a chain 07 and a driving machine 08. There are multiple sprockets 06 and all of them are rotatably supported on the frame 01. There are four sprockets 06 in the present application. The axis lines of the four sprockets 06 can define a rectangular area, and the axis lines of the sprockets 06 are perpendicular to the vertical plane; the chain 07, which is closed at both ends, is simultaneously mounted on multiple sprockets 06, and the shape defined by the center line of the chain 07 is the same as the shape defined by the center line of the support track 02. Along the axis line direction of the sprocket 06, the chain 07 is directly opposite to the support track 02, and the mounting frame 03 is connected to a chain plate of the chain 07; the driving machine 08 is fixed on the frame 01 and its output shaft is coaxially fixed with a sprocket 06; the driving machine 08 drives a sprocket 06 to rotate, and when the sprocket 06 rotates, it drives the remaining sprockets 06 to rotate through the chain 07. When the chain 07 is running, it drives the mounting frame 03 to move, and the direction of movement of the mounting frame 03 is the same as the length direction of the support track 02;

[0041] The disinfection assembly includes a nozzle 10, a liquid medicine tank 11 and a pump body 12. The nozzle 10 is mounted on the mounting frame 03, and the spray direction of the nozzle 10 is toward the inner side of the area surrounded by the support track 02; the liquid medicine tank 11 contains disinfectant liquid, and the liquid medicine tank 11 has a liquid filling port, through which water and disinfectant can be added to the liquid medicine tank 11, and the liquid outlet of the liquid medicine tank 11 is connected to the nozzle 10, and the water channel between the two is connected in series with the pump body 12; the pump body 12 will pump the disinfectant liquid in the liquid medicine tank 11 to the nozzle 10;

[0042] The mesh plate 13 is arranged horizontally and is located inside the area surrounded by the support track 02. The nozzle 10 can be located below the mesh plate 13. The pig farm entrance vehicle can travel on the mesh plate 13 and pass through the area surrounded by the support track 02. After the pig farm entrance vehicle travels onto the mesh plate 13, the driving machine 08 drives the nozzle 10 to move along the length direction of the support track 02. The nozzle 10 can spray the disinfectant liquid onto the surface of the pig farm entrance vehicle, including the front, rear, left, right, top and bottom of the pig farm entrance vehicle. Because the disinfectant liquid sprayed by the nozzle 10 is in mist and diverges in a cone shape, the front and rear sides of the pig farm entrance vehicle can be exposed to the disinfectant liquid. Alternatively, a separate staff member is equipped, and the staff member carries a sprayer filled with disinfectant liquid and manually sprays the disinfectant liquid on the front and rear sides of the pig farm entrance vehicle.

[0043] There are two support rails 02, which are arranged in sequence along a direction perpendicular to the vertical plane. The mounting frame 03 is slidably connected to the two support rails 02 at the same time, and the mounting frame 03 can stably slide on the support rails 02;

[0044] More specifically, the support and limit assembly also includes a support shaft 04 and a limit wheel 05. The inner side wall of the support track 02 is provided with a T-shaped slide groove 020 closed at both ends. The support shaft 04 and the limit wheel 05 are both located in the T-shaped slide groove 020. Two support shafts 04 are arranged in each T-shaped slide groove 020. The two support shafts 04 are arranged in sequence along the groove length direction of the T-shaped slide groove 020. The axial length direction of the support shaft 04 is parallel to the axis of the sprocket 06. Both ends of each support shaft 04 are coaxially supported to have a limit The limiting wheel 05 and the notch of the T-shaped slide groove 020 are located between the two limiting wheels 05 connected to the same support shaft 04. The outer wall of the limiting wheel 05 can roll and abut against the bottom wall or the top wall of the T-shaped slide groove 020. When the chain 07 drives the mounting frame 03 to move, the limiting wheel 05 can reliably roll in the T-shaped slide groove 020. The mounting frame 03 has two connecting ends, and the two connecting ends are respectively arranged in two T-shaped slide grooves 020. Multiple support shafts 04 in the same T-shaped slide groove 020 are fixed to one connecting end.

[0045] More specifically, it also includes a telescopic assembly, which includes a telescopic cylinder 14, a connecting rod 15, a distance sensor 16 and a controller 17;

[0046] The telescopic cylinder 14 is fixed on the mounting frame 03, and the telescopic cylinder 14 is located between the two supporting rails 02, and the telescopic direction of the telescopic end of the telescopic cylinder 14 is perpendicular to the axis of the sprocket 06;

[0047] The length direction of the connecting rod 15 is perpendicular to the vertical plane. The connecting rod 15 is located inside the area surrounded by the support track 02. The nozzle 10 is fixed on the connecting rod 15. There are multiple nozzles 10 and they are arranged equidistantly in sequence along the length direction of the connecting rod 15.

[0048] There are multiple distance measuring sensors 16 and they are all fixed on the connecting rod 15. The multiple distance measuring sensors 16 are arranged in sequence and at equal distances along the length direction of the connecting rod 15.

[0049] The controller 17 is mounted on the frame 01, and the driving machine 08, the pump body 12, the telescopic cylinder 14 and the distance sensor 16 are all electrically connected to the controller 17;

[0050] The telescopic cylinder 14 can drive the connecting rod 15 to move, so that the connecting rod 15 can approach or move away from the pig farm entrance vehicle located on the mesh plate 13, thereby allowing the nozzle 10 to approach or move away from the pig farm entrance vehicle; the telescopic cylinder 14 is combined with the design of the distance measuring sensor 16, so that a certain distance can be maintained between the nozzle 10 and the pig farm entrance vehicle. The disinfection device can effectively disinfect pig farm entrance vehicles of different sizes. The nozzle 10 will not collide with the pig farm entrance vehicle or the mesh plate 13 during the movement, and the surface of the pig farm entrance vehicle can be fully sprayed with disinfectant liquid to ensure the disinfection effect.

[0051] More specifically, it also includes a guide assembly, two guide assemblies are provided, and the chain 07 and the telescopic cylinder 14 are both located between the two guide assemblies;

[0052] The guide assembly includes a sleeve 18, a guide rod 19 and a stopper 20. The sleeve 18 is fixed on the mounting frame 03. A through hole is opened on the mounting frame 03, and the through hole is opposite to and connected with the sleeve 18. The guide rod 19 is slidably inserted in the sleeve 18 and the through hole. One end of the guide rod 19 is fixed to the connecting rod 15, and the other end of the guide rod 19 is fixed to the stopper 20. The length direction of the guide rod 19 is the same as the telescopic direction of the telescopic end of the telescopic cylinder 14. The outer contour diameter of the stopper 20 is larger than the inner diameter of the sleeve 18. The telescopic cylinder 14 can drive the connecting rod 15 to move stably.

[0053] More specifically, the driving assembly also includes a connecting member 09 , one end of the connecting member 09 is fixed to the mounting frame 03 , and the other end of the connecting member 09 is fixed to a chain plate of the chain 07 . In this embodiment, the connecting member 09 is fixed to an inner chain plate of the chain 07 .

[0054] Two support members 21 are provided on the frame 01. The support members 21 have a running surface arranged obliquely relative to the horizontal plane. The upper ends of the two running surfaces are respectively connected to the two ends of the mesh plate 13. The inclined running surface can ensure that the vehicles entering the pig farm can smoothly drive onto the mesh plate 13. At the same time, the two support members 21 can effectively support the mesh plate 13.

[0055] Two mesh plates 13 are provided, the length direction of the mesh plates 13 is perpendicular to the vertical plane, the length directions of the two mesh plates 13 are the same, there is a gap between the two mesh plates 13, one end of the two mesh plates 13 is fixed to a support member 21 at the same time, and the wheels on both sides of the vehicle entering the pig farm can respectively roll and abut against the upper plate surfaces of the two mesh plates 13; this design can improve the spraying effect of the disinfectant solution on the bottom of the vehicle entering the pig farm.

[0056] When the pig farm entry vehicle disinfection device is in use:

[0057] Before the pig farm entry vehicle is about to drive to the upper plate surface of the mesh plate 13, the telescopic cylinder 14 is in a retracted state, and the nozzle 10 is under the mesh plate 13;

[0058] When a pig farm entry vehicle drives onto the mesh plate 13, the pig farm entry vehicle stops moving forward and ensures that the pig farm entry vehicle is arranged between the two nozzles 10 on the connecting rod 15 and close to its two ends;

[0059] The staff starts the driving machine 08 and the pump body 12 for the first time, and the driving machine 08 drives the spraying nozzle 10 to move; when the staff observes that the nozzle 10 moves above the mesh plate 13, the driving machine 08 is stopped and the telescopic cylinder 14 is controlled to start the first extension action, so that the nozzle 10 approaches the pig farm entry vehicle, and when the distance measuring sensor 16 detects that the distance between it and the left surface of the pig farm entry vehicle reaches a certain value, the telescopic cylinder 14 automatically stops the extension action;

[0060] Then the staff starts the driving machine 08 for the second time, and the nozzle 10 moves upward while spraying, so as to disinfect the left surface of the vehicle entering the pig farm; when the staff observes that the nozzle 10 moves to the upper left of the vehicle entering the pig farm, the driving machine 08 is controlled to stop and the telescopic cylinder 14 is retracted;

[0061] When the telescopic cylinder 14 is retracted and reset, the staff starts the driving machine 08 for the third time, and the nozzle 10 is converted from vertical movement to horizontal movement to achieve the disinfection of the top of the pig farm entry vehicle. Note that when the top of the pig farm entry vehicle is disinfected, the telescopic cylinder 14 is in a retracted state, because the nozzle 10 sprays downward, and most of the disinfectant liquid sprayed by the nozzle 10 can successfully fall on the top of the pig farm entry vehicle. At this time, there is no need to consider the distance between the nozzle 10 and the top of the pig farm entry vehicle;

[0062] When the staff observes that the nozzle 10 moves from the left side of the pig farm entrance vehicle to the right side and starts to move downward, the driving machine 08 is controlled to stop and the telescopic cylinder 14 is controlled to start the second extension action, so that the nozzle 10 approaches the pig farm entrance vehicle. When the distance measuring sensor 16 detects that the distance between it and the right side surface of the pig farm entrance vehicle reaches a certain value, the telescopic cylinder 14 automatically stops the extension action;

[0063] Then the staff started the driving machine 08 for the fourth time, and the nozzle 10 moved downward while spraying, thereby disinfecting the right side surface of the vehicle entering the pig farm; when the staff observed that the nozzle 10 was about to move below the mesh plate 13, the driving machine 08 was controlled to stop and the telescopic cylinder 14 was retracted;

[0064] When the telescopic cylinder 14 is retracted and reset, the staff starts the driving machine 08 for the fifth time, and the nozzle 10 is converted from vertical movement to horizontal movement to achieve the disinfection of the bottom of the vehicle entering the pig farm; after the nozzle 10 moves horizontally for a certain distance below the mesh plate 13, the driving machine 08 and the pump body 12 are controlled to stop;

[0065] Since the pig farm entrance vehicle is arranged between the two nozzles 10 on the connecting rod 15 and near its two ends, combined with the movement of the nozzles 10 and the divergent spray, the front and rear ends of the pig farm entrance vehicle can also be exposed to the disinfectant solution, thereby achieving disinfection of the front and rear ends of the pig farm entrance vehicle.

[0066] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0067] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
