Description
Technical Field
[0001] This utility model relates to the technical field of pensing devices, and in particular to an automatic weighing and pensing device for animal husbandry and veterinary medicine. Background Technology
[0002] Currently, with the rapid development of the meat and livestock industry, there are more and more intensive and large-scale farms. In order to achieve refined management, it is necessary to keep track of the livestock's physical condition and weight at all times and formulate different daily rations according to different nutritional and production needs. Therefore, in order to solve the problem of rapid weighing and grouping of livestock, it is necessary to develop an automated and highly accurate automatic weighing and grouping system for livestock.
[0003] Most existing weighing and pensing devices use a double-opening gate structure. When opening the gate, it is very easy to touch the livestock. If the force is too great, it will cause stress to the livestock. At the same time, during the weighing process, mud, dust or feces are easily left on the weighing platform, which affects the measurement accuracy and causes pensing errors. Utility Model Content
[0004] To address the problems mentioned in the background section, this invention provides an automatic weighing and sorting device for livestock and veterinary medicine.
[0005] The technical solution of this utility model to achieve the above objectives is an automatic weighing and sorting device for animal husbandry and veterinary medicine, comprising:
[0006] The column frame has cleaning openings on the lower part of its two side surfaces and observation openings on the upper part of its two side surfaces, with glass panels installed inside the observation openings.
[0007] The electronic platform scale is installed inside the lower part of the column frame, with both ends inserted into the cleaning port;
[0008] The weighing instrument is installed at the center of one end of the column frame and is electrically connected to the electronic platform scale.
[0009] The zeroing button is installed on the vertical frame at one end of the column frame and is electrically connected to the weighing instrument.
[0010] The column ramp is installed at one end of the column frame, with guardrails installed at both ends of its upper surface and connected to the column frame. An input panel is installed on one of the guardrails and is electrically connected to the weighing instrument.
[0011] A retractable gate mechanism, located at the four corners inside the column frame, includes:
[0012] Electric push rods are installed on both sides of the center of the vertical frame of the column frame and are symmetrically distributed. A horizontal adjustment rod is installed at the telescopic end of the rod, and a hinge seat is installed at one end of the horizontal adjustment rod. The hinge seat is set outside the vertical frame of the column frame and slides in contact with the vertical frame of the column frame.
[0013] The gateposts are installed on one side of the vertical frame of the partition frame, at both ends of one side surface.
[0014] The hinged strut is movable and hinged to the hinged seat.
[0015] 90° bends are set inside the vertical frames of the column frame, evenly distributed, and corresponding to the positions of the vertical bars of the gate.
[0016] A horizontal bar square box is installed on one side of the vertical frame of the column frame and contacts the glass panel. A limiting vertical bar is set inside it.
[0017] The horizontal flexible rod is movably inserted into a 90° bend, with one end connected to the gate vertical rod and the other end connected to the limiting vertical rod.
[0018] In this utility model, a pressing protrusion is installed on the side surface of one of the gate vertical bars, and the pressing protrusion corresponds to the position of the zeroing button.
[0019] In this invention, the gate's vertical bar extends close to the vertical frame of the partition frame as the electric push rod extends, causing the pressing protrusion to press the zeroing button, thereby causing the weighing instrument's measurement value to return to zero.
[0020] In this invention, the upper surface of the electronic platform scale and the upper surface of the dividing ramp are on the same horizontal plane and are separated by a small gap.
[0021] In this invention, the input panel has number buttons, and the animal's ear number is input into the weighing instrument.
[0022] In this invention, the transverse flexible rod is composed of a rubber flexible rod with a flexible steel cable embedded in the center.
[0023] In this invention, the weighing instrument is equipped with a wireless transmission module to upload weighing data to a mobile terminal in real time.
[0024] In this invention, when the retractable gate mechanism is closed, the distance between the two gate vertical bars at the same end of the partition frame is relatively small.
[0025] In this invention, infrared ranging sensors are installed at the center of the upper part of both ends of the column frame.
[0026] Compared with the prior art, the beneficial effects of this utility model are:
[0027] 1. The retractable gate mechanism avoids contact with livestock when opening and closing the gate, thus preventing stress to the animals. It also optimizes space design, reduces the overall footprint of the device, and the automatic zeroing of the weighing when the gate is opened effectively ensures weighing accuracy and reduces errors.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] This utility model provides a technical solution, such as Figures 1-5As shown; an automatic weighing and pensing device for animal husbandry and veterinary use includes: a pensing frame 1, with cleaning openings 11 on the lower part of its two side surfaces and observation openings on the upper part of its two side surfaces, with glass panels 12 installed inside the observation openings; an electronic platform scale 2, installed inside the lower end of the pensing frame 1, with both ends inserted into the cleaning openings 11; and a weighing instrument 3, installed at the center of one end of the pensing frame 1 and electrically connected to the electronic platform scale 2.
[0039] In this embodiment of the utility model, the electronic platform scale 2 is placed inside the cleaning port 11, so that the electronic platform scale 2 can be cleaned to both sides after use, making it easier to clean the electronic platform scale 2 and making it more convenient to use.
[0040] In this embodiment of the invention, by using the electronic platform scale 2 and the weighing instrument 3, livestock can be automatically weighed and the weight can be displayed and stored for refined management of livestock.
[0041] In this embodiment of the invention, the glass panel 12 inside the observation port can be replaced with a transparent plastic plate or a transparent rubber plate to reduce the cost of the device and avoid the problem of the observation glass 12 breaking and affecting its use.
[0042] Zeroing button 4 is installed on the vertical frame at one end of the column frame 1 and is electrically connected to the weighing instrument 3; column ramp 5 is installed at one end of the column frame 1, with guardrails 51 installed at both ends of its upper surface and connected to the column frame 1, and an input panel 52 is installed on one of the guardrails 51, which is electrically connected to the weighing instrument 3.
[0043] In this embodiment of the utility model, the zeroing button 4 is provided so that after the retractable gate mechanism 6 is opened, the zeroing button 4 can be pressed to reset the measurement value of the electronic platform scale 2 to zero, so as to perform high-precision measurement in the future, while avoiding measurement errors caused by mud, dust or feces falling onto the electronic platform scale 2.
[0044] In this embodiment of the utility model, the use of the protective fence 51 and the partition ramp 5 allows livestock to be pre-lined so that they can be weighed and partitioned one by one. At the same time, the use of the input panel 52 allows staff to input the livestock number into the weighing instrument 3 to understand the actual growth condition and weight of the livestock, and to carry out refined management of the livestock.
[0045] In this embodiment of the invention, an RFID reading module may be installed inside the input panel 52, enabling it to automatically identify the identification information on the animal's ears, thereby automating data collection, reducing manual input errors, and saving manpower.
[0046] A retractable gate mechanism 6 is located at the four corners inside the column frame 1. It includes: an electric push rod 61, symmetrically distributed on both sides of the center of the vertical frame of the column frame 1, with a horizontal adjusting rod 611 installed at its telescopic end. A hinge seat 612 is installed at one end of the horizontal adjusting rod 611, and the hinge seat 612 is located outside the vertical frame of the column frame 1 and slides in contact with it; and a gate vertical rod 62, located on one side of the vertical frame of the column frame 1, with hinge supports movably installed at both ends of its side surface. The rod 621 is hinged to the hinge seat 612; the 90° bend 63 is set inside the vertical frame of the partition frame 1 and is evenly distributed, corresponding to the position of the gate vertical rod 62; the horizontal bar box 64 is installed on one side of the vertical frame of the partition frame 1 and contacts the glass panel 12, and a limiting vertical rod 641 is set inside it; the horizontal flexible rod 65 is movably inserted into the 90° bend 63, one end of which is connected to the gate vertical rod 62 and the other end is connected to the limiting vertical rod 641.
[0047] In this embodiment of the utility model, the electric push rod 61 is used to drive the hinged support rod 621 to move the gate vertical rod 62 closer to or away from the vertical frame of the partition frame 1, thereby controlling the opening or closing of the gate, thus avoiding contact between the gate and the livestock when the gate is opened or closed, so as to avoid causing stress to the livestock.
[0048] In this embodiment of the utility model, the rotation of the hinged support rod 621 and the deformable guidance of the transverse flexible rod 65 through the 90° bend 63 enable the gate vertical rod 62 to be opened or closed by translation, thereby making reasonable use of space and reducing its occupied area.
[0049] In this utility model, a pressing protrusion 622 is installed on the side surface of one of the gate vertical bars 62, and the pressing protrusion 622 corresponds to the position of the zeroing button 4; so that the pressing protrusion 622 can press the zeroing button 4 after the gate is opened.
[0050] In this utility model, the gate vertical bar 62 extends close to the vertical frame of the partition frame 1 as the electric push rod 61 extends, causing the pressing protrusion 622 to press the zeroing button 4, thereby causing the measurement value of the weighing instrument 3 to return to zero; so that when the next animal is weighed and partitioned, the electronic platform scale 2 can automatically return to zero.
[0051] In this invention, the upper surface of the electronic platform scale 2 and the upper surface of the partition ramp 5 are on the same horizontal plane and are separated by a small gap, so as to facilitate the movement of livestock onto the electronic platform scale 2.
[0052] In this invention, the input panel 52 has digital buttons, and the animal ear number is entered into the weighing instrument 3; this facilitates the entry of animal number data so that the weight of the animals can be recorded and stored one by one, so as to grasp the actual growth of the animals.
[0053] In this invention, the transverse flexible rod 65 is composed of a rubber flexible rod with a flexible steel cable embedded in the center; this ensures the strength of the transverse flexible rod 65 and allows it to bend with the 90° bend 63.
[0054] In this invention, the weighing instrument 3 is equipped with a wireless transmission module to upload weighing data to a mobile terminal in real time; this facilitates the transmission of measurement data so that staff can organize and store the measurement data.
[0055] In this utility model, when the retractable gate mechanism 6 is closed, the two gate vertical bars 62 at the same end of the partition frame 1 are spaced at a small distance; an infrared ranging sensor 13 is installed at the center of the upper part of both ends of the partition frame 1; this reduces the mutual collision of the gate vertical bars 62, thereby reducing the noise of the device, and at the same time, it facilitates the measurement of whether the livestock have completely exited the electronic platform scale 2.
[0056] When using this utility model, the staff drives the livestock to the front of the pen frame 1 and moves the livestock to the pen ramp 5. Then the staff observes the current livestock number and enters the information through the input panel 52. After the information is entered, the two retractable gate mechanisms 6 at the front of the pen frame 1 begin to open.
[0057] At this time, the corresponding electric push rod 61 starts to extend. The extension of the electric push rod 61 drives the horizontal adjustment rod 611 and the hinge seat 612 to move. Then, the two hinge support rods 621 drive the gate vertical rod 62 to move closer to the vertical frame of the partition frame 1 until the electric push rod 61 is fully extended. At this time, the gate is in the open state. At the same time, press the protrusion 622 to press the zero button 4 to make the measurement value of the electronic platform scale 2 return to zero.
[0058] Then, the staff can drive the livestock to move them onto the electronic platform scale 2. When the livestock are completely inside the pen frame 1, the value detected by the infrared distance sensor 13 at the front end of the pen frame 1 is close to the set value. After waiting for a few seconds, the staff controls the electric push rod 61 to start retracting, so that it uses two hinged support rods 621 to push the gate vertical rod 62 away from the vertical frame of the pen frame 1 until the electric push rod 61 is fully retracted. At this time, the gate is in the closed state.
[0059] Then, the weight of the livestock can be measured by the electronic platform scale 2 for a few seconds to ensure the accuracy of the measurement results. After that, the two retractable gate mechanisms 6 at the rear of the pen frame 1 can be controlled to open, allowing the livestock to walk out of the pen frame 1.
[0060] After the livestock walks out of the pen frame 1, it moves to the corresponding pen according to the weight on the weighing instrument 3. At this time, the detection value of the infrared ranging sensor 13 at the rear end of the pen frame 1 is close to the set value. After waiting for a few seconds, the two retractable gate mechanisms 6 at the rear end of the pen frame 1 are controlled to close, and the weighing and penning of the livestock is completed.
[0061] When weighing livestock again, staff can enter the livestock number again through input panel 52, and then repeat the above operation.
[0062] After the device is used up, the staff controls the retractable gate mechanism 6 to open, and then the electronic platform scale 2 can be cleaned and the garbage can be cleaned out through the cleaning ports 11 on both sides.
