Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically a feed-pushing robot for cattle farms. Background Technology

[0002] Modern large-scale cattle farms typically employ intensive penning for feeding. When feeding the cattle, the feed should be placed at the outer edge of the pen for easy access. However, as the cattle root for the feed, they often push it far outside the pen. Therefore, it's necessary to continuously move the feed from the outer edge back to the pen's outer edge during feeding. To address this issue, many large-scale cattle farms in China are now using specialized feed-pushing robots.

[0003] Currently, the feed-pushing robots used in cattle farms include a self-rotating, attitude-adjustable hay-pushing robot disclosed in patent CN118923548A. Its structure is similar to a household robotic vacuum cleaner, offering timely and safe feed delivery, but its complex structure has led to high user costs. Patent CN221235971U discloses a cleaning device for an adjustable feed-pushing robot, which also has a relatively complex structure and suffers from poor cleaning paths in practical applications. Utility Model Content

[0004] In view of the problems pointed out in the background art, the purpose of this utility model is to propose a feeding robot for cattle farms, which aims to solve the problems of complex structure and high cost of existing feeding robots. At the same time, this utility model has a simple structure, is easy to maintain, and has convenient and quick path planning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A feeding robot for cattle farms includes a vehicle body, a bucket, a fixed shaft, and an electric push rod. The bottom of the vehicle body is equipped with steering wheels and drive wheels. The fixed shaft is a horizontal shaft, with both ends connected to the front of the vehicle body. The angle between the fixed shaft and the axis of the drive wheel at the bottom of the vehicle body is α, where 20°≤α≤70°. The bucket is rotatably hinged to the fixed shaft. One end of the electric push rod is rotatably hinged to the vehicle body, and the other end is rotatably hinged to the bucket. A brush and / or a Teflon shovel plate are connected to the bottom edge of the bucket opening.

[0006] The vehicle body is equipped with an electrical box, which contains an on-board battery and a controller. The on-board battery is connected to the power port of the electric push rod, and the controller is connected to the drive motor of the electric push rod, the steering actuator of the steering wheel, and the actuator of the drive wheel.

[0007] The steering wheel is the front wheel, and the drive wheel is the rear wheel; there is one steering wheel.

[0008] The steering actuator of the steering wheel is a steering motor, which is fixed to the vehicle body and powered by the vehicle battery.

[0009] The actuator of the drive wheel is a hub motor, which is installed inside the drive wheel, and the power port of the hub motor is connected to the vehicle battery.

[0010] The fixed shaft is connected to mounting seats at both ends, and the two ends of the fixed shaft are fixedly connected to the front of the vehicle body through the mounting seats.

[0011] The bucket is provided with a first hinge seat in the middle and a second hinge seat at each end of the bucket; the middle of the bucket is rotatably hinged to the electric push rod through the first hinge seat, and the two ends of the bucket are rotatably hinged to the fixed shaft through the corresponding second hinge seats.

[0012] The upper end of the Teflon shovel plate is connected to the bottom edge of the bucket opening, and the brush is connected to the lower end of the Teflon shovel plate.

[0013] The brush is connected to the bottom edge of the bucket opening.

[0014] The beneficial effects of this utility model are as follows: because there is an angle between the fixed shaft and the axis of the vehicle's drive wheel, and an angle is also formed between the bucket and the axis of the vehicle's drive wheel, when the vehicle moves forward in a straight line, it can push the feed scattered far outside the cattle pen to the edge of the cattle pen. Compared with the prior art, the rotating sweeping mechanism is omitted, and the path planning is simpler and more convenient. The whole machine is a fully electric tricycle, which has low manufacturing cost and is easy to maintain. Attached Figure Description
