Description

Technical Field

[0001] The present application relates to the technical field of breeding, and in particular to an intelligent pig passage anti-backflow device. Background Art

[0002] In animal husbandry, pig management and transportation is an important link. At present, when weaned, culled or fattened pigs are loaded onto external vehicles for transportation, they may return to the original farm due to fright or other reasons. This is because pigs need to directly or indirectly contact a large number of people and vehicles inside and outside the farm during the process of leaving the farm, which may bring unknown pollutants from external vehicles into the farm, posing a serious threat to the biosafety of the farm.

[0003] The existing pig driving gate design is usually a switch door that can be opened and closed at any time. It is set in the channel for transferring pigs. When pigs need to pass through, the switch door is opened manually and then closed again after the pigs pass through. However, this structure is difficult to effectively prevent pigs from flowing back during the pig exit process. Utility Model Content

[0004] In order to prevent backflow during pig transportation, the present application provides an intelligent pig backflow prevention device.

[0005] The present application provides an intelligent pig passage anti-backflow device, which adopts the following technical solutions:

[0006] An intelligent pig passage backflow prevention device comprises a rotating shaft beam and a non-return beam arranged along the width direction of a channel, a fixed rod arranged on the rotating shaft beam, and a movable rod rotatably arranged on the rotating shaft beam, wherein the movable rod is provided with a plurality of movable doors for pigs to pass through along the direction of the rotating shaft beam, and the fixed rod is provided with a plurality of movable rods between the movable rod and the side wall of the channel; when the pig passes through the channel in the forward direction and abuts against the movable rod, the movable rod can rotate in the direction away from the non-return beam, and after the pig passes through, the movable rod can rotate to an initial state; when the pig passes through the channel in the reverse direction and abuts against the movable rod, the movable rod is restricted from rotating by the non-return beam.

[0007] By adopting the above technical solution, the one-way passage and anti-backflow function of pigs are realized. When the pigs pass through in the forward direction, the movable rod can rotate freely; when the pigs try to pass through in the reverse direction, the movable rod is restricted by the non-return beam and cannot rotate, thereby preventing the pigs from flowing back, improving the breeding efficiency and management effect, and reducing the chaos caused by the backflow of pigs and the possible risk of biological contamination.

[0008] Optionally, a rotating sleeve is provided outside the rotating sleeve of the rotating shaft beam, and the movable rod is arranged on the rotating sleeve.

[0009] By adopting the above technical solution, a rotating sleeve is rotatably sleeved outside the rotating shaft beam, and the movable rod is arranged on the rotating sleeve, thereby enhancing the flexibility and stability of the rotation of the movable rod.

[0010] Optionally, it also includes a sensor, a counter and a display screen, wherein the sensor is used to detect the pigs passing through the movable door and transmit the signal to the counter, and the counter transmits the number of pigs to the display screen for display.

[0011] By adopting the above technical solution, setting up sensors, counters and display screens, the sensors can automatically detect the number of pigs passing through the movable door and display the number information in real time through the display screen; this design improves the intelligence and automation level of breeding management, allowing breeders to more easily grasp the passage of pigs.

[0012] Optionally, the sensor is an infrared sensor.

[0013] By adopting the above technical solutions, the infrared sensor has the advantages of accurate detection, rapid response, and strong anti-interference ability. It can improve the detection efficiency and accuracy of the device and further enhance the intelligent level of breeding management.

[0014] Optionally, it further includes two columns arranged on the side walls on both sides of the channel, and the rotating shaft beam and the non-return beam are arranged on the two columns.

[0015] By adopting the above technical solution, setting up the columns can facilitate the installation of the rotating shaft beam and the non-return beam.

[0016] Optionally, the rotating shaft beam and the non-return beam are fixed to the side walls of the column by welding.

[0017] Optionally, connecting plates are provided at both ends of the rotating shaft beam and the non-return beam, bolts and nuts are provided on the connecting plates, and positioning holes for the bolts to pass through are opened on the columns.

[0018] By adopting the above technical solution, the bolts and nuts on the connecting plate and the positioning holes on the column are used to realize the fixed connection between the rotating shaft beam and the non-return beam and the column, making the installation and disassembly of the device more convenient and quick, and also improving the stability and reliability of the device.

[0019] Optionally, a plurality of positioning holes are provided along the length direction of the column.

[0020] By adopting the above technical solution, the height of the rotating shaft beam and the non-return beam can be adjusted according to actual needs to adapt to pigs of different sizes, thereby further improving the flexibility and applicability of the device.

[0021] In summary, the present application includes at least one of the following beneficial effects:

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] Example 1

[0030] The present application embodiment discloses an intelligent pig passage anti-backflow device. Figure 1 The backflow prevention device includes a column 7, a rotating shaft beam 1 and a non-return beam 2, wherein two columns 7 are arranged along the vertical direction and are respectively fixed on the side walls on both sides of the channel, the rotating shaft beam 1 and the non-return beam 2 are arranged along the horizontal direction, and both ends are respectively fixed on the column 7, and also includes a fixed rod 3 arranged on the rotating shaft beam 1, and a movable rod 4 rotatably arranged on the rotating shaft beam 1, a plurality of movable rods 4 are arranged at intervals along the length direction of the rotating shaft beam 1, and a plurality of movable rods 4 together form a movable door for pigs to pass through; a plurality of fixed rods 3 are arranged at intervals on both sides of the movable door and between the two columns to limit the passage of pigs.

[0031] Reference Figure 1 and Figure 2In this embodiment, specifically, the shaft beam 1 and the non-return beam 2 are both configured as circular rods with hollow interiors, wherein the non-return beam 2 can be disposed above the shaft beam 1, and the fixed rod 3 and the movable rod 4 can also be configured as circular thin rods. The outer side wall of the shaft beam 1 can be rotatably connected to the rotating sleeve 11 by means of a bearing or a groove, and the movable rod 4 is fixed to the outer side wall of the rotating sleeve 11 by means of welding, bolts, etc., to achieve rotatable connection, and a plurality of rotating sleeves 11 and movable rods 4 are provided in a one-to-one correspondence.

[0032] Further, Figure 2 The orientation is used as a reference. At this time, the movable rod 4 is fixed to the left side of the rotating sleeve 11, the lower end of the movable rod 4 extends toward the ground, and the upper end extends upward to the right side of the non-return beam 2. It should be noted that at this time, the length of the movable rod 4 extending downward to the ground is greater than the length extending upward toward the non-return beam 2, so in the natural state, the movable rod 4 can maintain a nearly vertical state under the vertical action, and at the same time, the upper end side wall of the movable rod 4 can abut against the right side wall of the non-return beam 2; correspondingly, the fixed rod 3 can be fixed to the left side of the rotating shaft beam 1 by welding or the like, and the upper end is fixed to the right side of the non-return beam 2.

[0033] At this time, the direction from right to left is the positive direction. When the pig passes through the passage in the positive direction and touches the movable door, it can drive the upper end of the corresponding movable rod 4 to rotate in the clockwise direction, that is, to rotate away from the non-return beam 2, and the pig can pass through the movable door smoothly; correspondingly, the direction from left to right is the reverse direction. When the pig passes through the passage in the reverse direction and touches the movable door, it can apply a force to rotate the upper end of the movable rod 4 in the counterclockwise direction. At this time, the upper end of the movable rod 4 abuts against the non-return beam 2 and is restricted from rotating, that is, it can restrict the pig from passing through the movable door in the reverse direction, thereby achieving the effect of preventing backflow. Correspondingly, the positioning rod can be fixed by welding to the left side of the rotating shaft beam 1 and the right side of the non-return beam 2.

[0034] The above method is only a preferred solution. In other embodiments, the movable rod 4 may also have other fixing methods. Figure 2 Taking the current position as a reference, the movable rod 4 can be fixed on the right side of the rotating sleeve 11, and the upper end of the movable rod 4 extends upward and is also located on the right side of the check beam 2. At this time, from right to left is the forward channel, and from left to right is the reverse channel, which can also achieve the effect of preventing backflow.

[0035] Reference Figure 1 and Figure 2Optionally, the shaft beam 1 can be arranged above the non-return beam 2, and the rotating sleeve 11 can be sleeved on the shaft beam 1. In this case, the movable rod 4 is welded to the left side of the rotating sleeve 11, and the rotating sleeve 11 is extended downward from the right side of the non-return beam 2 to the ground, so that the forward channel is from left to right, and the reverse channel is from right to left. As long as the combination of the non-return beam 2 and the shaft beam 1 can realize one-way flow, it belongs to the protection scope of this application.

[0036] Reference Figure 1 and Figure 2 In this embodiment, the cross section of the column 7 can be "L" shaped, and one side wall of the column 7 abuts against the channel side wall and can be fixed to the channel side wall by nails or expansion screws. The two ends of the non-return beam 2 and the shaft beam 1 can be fixed to the other outer side wall of the column 7 by welding.

[0037] Reference Figure 1 and Figure 2 In an optional embodiment, the backflow prevention device may further include a sensor 5, a counter (not shown in the figure) and a display screen 6. The sensor 5 is responsible for detecting the pigs passing through the movable door and transmitting the detection signal to the counter. The counter counts the number of pigs passing through and then transmits the number information to the display screen 6 for real-time display. This intelligent improvement enables managers to intuitively understand the passage of pigs, providing convenience for accurate management and monitoring.

[0038] Among them, the sensor 5 is preferably an infrared sensor 5, and the sensor 5, the counter and the display screen 6 can all be arranged on the column 7. Among them, the sensor 5 is preferably arranged on the side of the column 7 close to the exit, that is, the pigs are sensed when they enter the range of the movable door, and are counted by the sensor 5 after passing through the movable door. This method can improve the counting accuracy; the display screen 6 is preferably fixed on the upper surface of the column 7 to facilitate the staff to observe the display screen 6.

[0039] The implementation principle of an intelligent pig passage anti-backflow device in an embodiment of the present application is: when in use, after the pig enters the transfer channel, it approaches the movable door in the forward direction and drives the movable rod 4 to rotate by contact, and the pig can then pass through the movable door. At this time, the sensor 5 senses the pig passing through, and can count and transmit the count to the display screen 6 for real-time display; when the pig passes through, the movable rod 4 naturally falls back under the action of gravity and returns to its original state, and the next pig can continue to pass through; when a pig wants to pass through the movable door in the reverse direction, the check beam 2 will limit the reverse rotation of the movable rod 4, thereby preventing the pig from flowing back.

[0040] Example 2

[0041] The difference between this embodiment and the first embodiment is that the fixing method of the non-return beam 2 and the rotating shaft beam 1 is different. Figure 3In this embodiment, the non-return beam 2 and the shaft beam 1 are detachably fixed to the column 7. Specifically, a connecting plate 8 is welded at both ends of the shaft beam 1 and the non-return beam 2. The connecting plate 8 is a rectangular plate and can be attached to the side wall of the column 7. Bolts and nuts are provided on the connecting plate 8. The bolts and nuts can be provided at the upper and lower ends of the connecting plate 8, respectively. A positioning hole 71 for the bolt to pass through is provided on the column 7. The positioning hole 71 is provided corresponding to the bolt. When the bolt passes through the connecting plate 8 and the positioning hole 71 in sequence and cooperates with the nut, the connecting plate 8 can be fixed to the column 7.

[0042] Furthermore, a plurality of positioning holes 71 can be provided along the length direction of the column 7, that is, along the vertical direction, at intervals on the column 7, so that the heights of the rotating shaft beam 1 and the non-return beam 2 can be adjusted to accommodate pigs of different sizes.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
