Description

Technical Field

[0001] This utility model relates to the field of automated livestock breeding equipment technology, and in particular to an intelligent feed dispensing robot with weighing function. Background Technology

[0002] In large-scale livestock farming, precise feeding is a key step in ensuring healthy animal growth and saving feed costs. Traditional feed feeding methods mostly rely on manual or simple mechanical timed feeding, which have problems such as inaccurate feeding amounts, inability to adjust according to individual or group needs, and high labor intensity.

[0003] Existing technologies include automated feeding devices, such as track-based feeding trolleys. However, these devices often lack effective weighing feedback mechanisms, failing to monitor the feeding amount in real time, leading to deviations between the actual feeding amount and the set value. Some devices integrate weighing sensors, but their installation location or structural design is unreasonable. For example, placing the weighing unit on the wheels or axles of the traveling trolley can be severely affected by factors such as track flatness and trolley vibration, resulting in unstable and inaccurate weighing data, thus affecting the control effect of precise feeding. Alternatively, radar / ultrasonic measuring instruments may be installed, emitting signals to the material surface and calculating the distance by calculating the time or parameter changes of signal transmission and return, thereby calculating the material level height. However, the accuracy may be significantly affected by dust, temperature, and the grain's angle of repose.

[0004] Furthermore, existing feeding equipment has complex feeding control mechanisms, poor sealing leading to feed waste, or slow response affecting control accuracy. Therefore, there is an urgent need in this field for an intelligent feed feeding robot that can achieve accurate and stable weighing and has reliable feeding control functions. Utility Model Content

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figures 1 to 4 As shown in the figure, this embodiment provides an intelligent feed dispensing robot with weighing function. This robot is mainly used for automated feed dispensing in pigsties, cattle sheds and other breeding facilities.

[0026] Two parallel guide rails 200 are mounted above the feed trough 100. The traveling trolley 300 is supported on the guide rails 200 by four track wheels 304 at its bottom. Limiters 201 are installed at both ends of the guide rails 200 to restrict the position of the traveling trolley 300 and protect the safety of the feeding robot. The traveling trolley 300 includes a support plate 301, with a front support axle 303 and a rear drive axle 302 respectively mounted on the front and rear sides of the bottom of the support plate 301. Track wheels 304 are installed at both ends of the two axles. The rear drive axle 302 has a built-in motor and reducer for driving the traveling trolley 300 to reciprocate along the guide rails 200.

[0027] The storage bin 400 is fixed to the support plate 301 of the traveling trolley 300 via its bottom support legs 406. The top of the bin 401 is fitted with a hinged top cover 402, which has a handle 404 for easy opening for cleaning or maintenance. A feeding port 403 is located on the top cover 402, with a one-way opening baffle. This baffle is connected to the top cover 402 via a spring hinge 4031. In its natural state, the baffle closes the feeding port 403 under spring force to prevent dust from entering. When external feed is supplied to the feeding port 403, the weight of the feed pushes open the baffle and into the bin. After feeding, the baffle automatically resets. A limiting protrusion 4032 on the top cover 402 limits the maximum opening angle of the baffle to prevent excessive tipping. A transparent feed level window 405 is installed on the side of the bin 401 for visually observing the remaining feed level.

[0028] The weighing unit consists of a support leg 406 and a weighing leg 4061 integrated at the bottom of the support leg 406. The weighing leg 4061 houses a high-precision load cell (such as a KELI SB series sensor), which is directly fixed to the support plate 301. This method of mounting the weighing unit close to the bottom of the storage hopper 400 allows for direct and accurate measurement of weight changes in the storage hopper 400 and its contents, with minimal impact from the movement and vibration of the traveling trolley 300.

[0029] The feeding mechanism 500 is mounted on the support plate 301 of the traveling trolley 300 and is located directly below the bottom discharge port 407 of the storage hopper 400. The feeding mechanism 500 includes an electric telescopic rod 501 and a control plate 502. The cylinder end of the electric telescopic rod 501 is hinged to the support plate 301 via a hinge seat. A long slot 305 is formed on the support plate 301, through which the electric telescopic rod 501 can pass. The control plate 502 includes a smooth rod 5021 fixed to the top of the support plate 301, a slider 5022 that is fitted onto the smooth rod 5021 and can slide, and a sliding plate 5023 fixedly connected to the slider 5022. One end of the sliding plate 5023 is hinged to the push rod end of the electric telescopic rod 501. When the electric telescopic rod 501 extends or retracts, it drives the slide plate 5023 to slide along the smooth rod 5021 above the long groove 305, thereby achieving precise control over the opening, closing, and opening size of the discharge port 407.

[0030] The robot is also equipped with a control system, which typically includes a PLC or microcontroller. This control system is electrically connected to the weighing sensor in the weighing leg 4061, the electric telescopic rod 501, and the drive motor of the walking trolley 300. The control system receives the weight signal from the weighing sensor and controls the movement of the walking trolley 300 and the action of the feeding mechanism 500 according to a preset program (such as timing, location, and quantity) to achieve fully automatic and precise feeding.

[0031] Working Process: The robot initially stands at the feeding station at one end of the feed trough 100, with the storage bin 400 filled with feed. The control system instructs the trolley 300 to move along the guide rail 200 to the first feeding point. Then, based on real-time data from the weighing unit, the control system controls the electric telescopic rod 501 to move, pushing the slide plate 5023 to open the feed inlet 407 for feeding. When the weighing unit detects that the amount of feed fed has reached the set value, the control system immediately instructs the electric telescopic rod 501 to retract, pulling the slide plate 5023 to close the feed inlet 407. Subsequently, the trolley 300 moves to the next feeding point, repeating the above process until the feeding task of the entire feed trough 100 is completed.

[0032] Example 2

[0033] like Figure 5 As shown, this embodiment has the same basic structure as Embodiment 1, the main difference being the installation method of the weighing unit and the structure of the feeding mechanism 500.

[0034] In this embodiment, the weighing unit is directly integrated between the support plate 301 of the traveling trolley 300 and the entire supporting bottom surface of the storage bin 400. Specifically, a large weighing platform (or weighing module) is installed on the upper surface of the support plate 301, and the storage bin 400 is directly placed and fixed on the weighing platform. This structure can also directly measure the total weight of the storage bin 400, and the installation is simpler.

[0035] Furthermore, the feeding mechanism 500 eliminates the structures of the smooth rod 5021 and the slider 5022. The slide plate 5023 is simplified into a flat plate directly hinged to the push rod end of the electric telescopic rod 501. A guide groove 306 is provided on the support plate 301. Guide protrusions are provided on both sides of the flat plate, and these guide protrusions are embedded in the guide grooves 306 on the support plate 301. When the electric telescopic rod 501 moves, the guide protrusions of the slide plate 5023 slide within the guide grooves 306 to achieve the guiding function. This design simplifies the structure and reduces manufacturing costs while ensuring guiding accuracy.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
