Description

Technical Field

[0001] This utility model relates to the field of non-contact measurement technology of beef cattle body size, and in particular to a non-contact measurement device for beef cattle body size. Background Technology

[0002] The beef cattle industry is an important agricultural sector. It not only provides beef, an important source of protein, but also promotes the development of the rural economy. Therefore, the daily monitoring of beef cattle is particularly important. Usually, people make judgments by measuring the height of the beef cattle.

[0003] For example, the patent for a non-contact measurement device for beef cattle body size, published under patent number CN215017423U, provides a non-contact measurement device for beef cattle body size, including an industrial control computer, an RFID reader, a gantry, and at least two depth cameras. When there are two depth cameras, one is located at the top of the gantry and the other at the side. The industrial control computer, RFID reader, and depth cameras are all mounted on the gantry. The RFID reader is used to identify electronic ear tags on the beef cattle. Both the RFID reader and the depth cameras are communicatively connected to the industrial control computer, and the depth cameras collect information about the beef cattle passing through the gantry.

[0004] However, because the depth camera is set on both sides and top of the gantry, when the cattle pass through the gantry, the area on the belly of the cattle or near the inside of the legs is affected by the interference of the cattle legs or the installation height of the depth camera, and the depth camera cannot collect image data, which can easily lead to measurement errors. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a non-contact measuring device for the body size of beef cattle.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a non-contact measuring device for beef cattle body size, comprising a gantry and several depth cameras. An embedded box is fixedly connected to the bottom of the gantry, and one of the depth cameras is slidably installed inside the embedded box. A lead screw is rotatably connected inside the embedded box, and a bottom slider threadedly connected to the lead screw and used to install the depth camera is slidably installed. The bottom of the gantry and the same side wall of the embedded box are both strip-shaped hollowed-out, and a connecting block connected to the bottom slider is slidably installed in the hollowed-out area. A baffle frame is fixedly connected to the top of the connecting block and arranged around the bottom slider. A transparent plate flush with the bottom of the gantry and slidably connected to the bottom edge of the baffle frame is inlaid at the opening of the embedded box. A water spray pipe is fixedly connected to the inner wall of one side of the baffle frame, and a drain pipe is fixedly connected through the inner wall of the opposite side.

[0007] Preferably, the water inlet of the spray pipe is fixedly connected to a flexible pipe, and the other end of the flexible pipe is provided with a water inlet pipe fixed to the bottom edge of the outer wall of the inner box facing away from the connecting block and used to connect to the water pump.

[0008] Preferably, a spring rod parallel to the lead screw is fixedly connected to the middle of the outer wall of the embedded box on the side facing away from the connecting block, and a fixed baffle is rotatably connected to the top edge of the middle. The telescopic end of the spring rod is fixedly connected to a movable baffle inserted into the outer wall of the embedded box in the horizontal direction, and the flexible tube passes through the surfaces of the fixed baffle and the movable baffle in sequence.

[0009] Preferably, vertically arranged side racks are fixedly connected to the inner walls on both sides of the gantry, and several side sliders are inserted into the back of the teeth of the side racks, with a depth camera installed on each of the side sliders.

[0010] Preferably, the side slider surface is rotatably connected to a gear that meshes with the tooth surface of the side rack.

[0011] Preferably, a top slider for mounting a top position depth camera is embedded and slidably connected within the inner top surface of the gantry. The top slider slides along the width direction of the gantry and is rotatably connected to a roller that is rolled within the inner top surface of the gantry.

[0012] Preferably, the rollers, gears, and lead screws are all driven by a motor.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an embedded box, a lead screw and a bottom slider are set inside the embedded box. The rotation of the lead screw causes the bottom slider to move the depth camera on its surface, so that the depth camera in the embedded box can take pictures of the belly of the beef cattle passing through the gantry. Combined with the depth cameras set on the side and top, it is possible to take pictures of the beef cattle's body from all angles as it passes through the gantry, ensuring that there will be no errors in the measurement.

[0015] 2. In this utility model, the rotation of the gear can cause it to roll on the side rack, thereby driving the side slider to rise and fall. This allows the depth camera mounted on the side slider to be adjusted adaptively according to the height of the passing cattle. Similarly, the rotation of the roller can be used to roll on the top of the gantry, thereby driving the top slider to move. This allows the depth camera mounted on the top slider to be adjusted adaptively according to the position of the cattle passing through the gantry. Attached Figure Description

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] like Figure 1-8As shown, a non-contact measurement device for beef cattle body size includes a gantry 1 and several depth cameras 13. The depth cameras 13 capture photos or videos of beef cattle passing through the gantry 1. Subsequent data analysis of the photos or videos yields relevant data about the beef cattle. An embedded box 4 is fixedly connected to the bottom of the gantry 1. One depth camera 13 is slidably mounted inside the embedded box 4. A lead screw 11 is rotatably connected inside the embedded box 4, and a bottom slider 12, threadedly connected to the lead screw 11 and used to mount the depth camera 13, is slidably mounted thereon. When the beef cattle pass through the gantry 1, based on the cattle's position, the lead screw 11 is driven to rotate, causing the bottom slider 12 to move the depth camera 13 below the cattle's body, thus acquiring an image of the cattle's abdomen as it passes. The bottom of the gantry 1 and the side walls of the embedded box 4 are both strip-shaped perforations. A connecting block 7 connected to the bottom slider 12 is slidably installed in the empty space. A baffle 6 is fixedly connected to the top of the connecting block 7 and is set around the bottom slider 12. A transparent plate 5 is embedded at the opening of the inner box 4, which is flush with the bottom of the frame 1 and slidably connected to the bottom edge of the baffle 6. The transparent plate 5 can prevent garbage from entering the inner box 4 and will not affect the operation of the depth camera 13. A water spray pipe 14 is fixedly connected to one inner wall of the baffle 6, and a drain pipe 8 is fixedly connected through the other inner wall. When the depth camera 13 in the inner box 4 is working, water is sprayed out through the water spray pipe 14 to rinse the area of ​​the transparent plate 5 covered by the baffle 6. The dirty water after rinsing flows out along the drain pipe 8, which can ensure that the lens of the depth camera 13 is unobstructed when it is working. In addition, the baffle 6 can also prevent the surrounding dirt from entering the area around the lens of the depth camera 13.

[0028] Additionally: A flexible pipe 16 is fixedly connected to the inlet of the spray pipe 14. The other end of the flexible pipe 16 is connected to an inlet pipe 9 fixed to the bottom edge of the outer wall of the inner box 4 facing away from the connecting block 7, which is used to connect to a water pump. By using a known water pump connected to the inlet pipe 9, water can be pumped to the spray pipe 14 along the inlet pipe 9 and the flexible pipe 16, and finally sprayed out. A spring rod 18, parallel to the lead screw 11, is fixedly connected to the middle of the outer wall of the inner box 4 facing away from the connecting block 7, and a fixed baffle 19 is rotatably connected to the top edge of the middle. A movable baffle 17, inserted horizontally into the outer wall of the inner box 4, is fixedly connected to the telescopic end of the spring rod 18. The flexible pipe 16 passes sequentially through the surfaces of the fixed baffle 19 and the movable baffle 17. Figure 5 As shown, when the bottom slider 12 moves to the left, it causes one end of the flexible tube 16 to move to the left, thereby pulling the entire flexible tube 16. This also causes the movable baffle 17 to move against the elastic force of the spring rod 18. During the movement, the position of the water inlet pipe 9 remains unchanged, and the flexible tube 16 remains taut and will not loosen or tangle. Conversely, when the bottom slider 12 moves to the left, it causes one end of the flexible tube 16 to move to the left, thus pulling the entire flexible tube 16. Figure 5As shown, when the bottom slider 12 moves to the right, under the restriction of the fixed baffle 19, the flexible tube 16 drives the fixed baffle 19 to rotate. When moving to the right, the flexible tube 16 is also pulled, which in turn drives the movable baffle 17 to move against the elastic force of the spring rod 18. During the movement, the position of the water inlet pipe 9 remains unchanged, and the flexible tube 16 remains taut and will not loosen or tangle. When the movement to the right is completed and the movement to the left is completed, or when the movement to the left is completed and the movement to the right is completed, the movable baffle 17 is reset by the elastic extension of the spring rod 18. This ensures that the flexible tube 16 will not loosen.

[0029] Additionally: Vertically arranged side racks 2 are fixedly connected to the inner walls of both sides of the gantry 1. Several side sliders 3 are inserted into the back of the teeth of the side racks 2. A depth camera 13 is mounted on each side slider 3. A gear 15 is rotatably connected to the surface of the side slider 3, meshing with the tooth surface of the side racks 2. By rotating the gear 15, the slider 3 rolls on the side racks 2, causing the side slider 3 to rise and fall. This allows the depth camera 13 mounted on the side slider 3 to adapt to the height of the passing cattle. A top slider 10 for mounting the top-positioned depth camera 13 is embedded and slidably connected to the inner top surface of the gantry 1. The top slider 10 extends along the width of the gantry 1. The top slider 10 is rotatably connected to a roller 20 that is rolled on the top surface of the gantry 1. Similarly, the roller 20 rotates and rolls on the top of the gantry 1, which drives the top slider 10 to move. This allows the depth camera 13 mounted on the top slider 10 to adapt to the position of the cattle as they pass through the gantry 1. The roller 20, gear 15, and lead screw 11 are all driven by a motor. By installing motors on the side slider 3, the top slider 10, and the inner box 4, the motor spindle passes through the installation position and rotates smoothly with the corresponding gear 15, roller 20, or lead screw 11.

[0030] The working principle is as follows: the gantry 1 is fixed in the installation position. When the beef cattle pass through the gantry 1, the height of the depth camera 13 on the side of the gantry 1 is adjusted by rotating the gear 15 to raise and lower the side slider 3 according to the height of the beef cattle and the left and right position of the beef cattle passing through the gantry 1. The position of the depth camera 13 on the side of the gantry 1 is adjusted by rotating the roller 20. The position of the depth camera 13 on the top of the gantry 1 is adjusted by rotating the lead screw 11 to move the bottom slider 12 to move the depth camera 13 in the embedded box 4. This ensures that the depth camera 13 on the side can cover the side of the beef cattle, the depth camera 13 on the top can cover the back of the beef cattle, and the depth camera 13 in the embedded box 4 can cover the belly of the beef cattle. As the beef cattle pass through, the gantry 13 can acquire images of the beef cattle's body from all directions.

[0031] The wiring diagrams of the motor, water pump, and depth camera 13 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the motor, water pump, and depth camera 13 will not be explained in detail.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
