Abstract
Description
Technical Field
[0001] This utility model relates to the field of material pushing technology, and in particular to a material pushing robot. Background Technology
[0002] In dairy farming, Total Mixed Ration (TMR) is often used for automated feeding. This method requires specialized processing equipment to mix roughage, concentrates, and other additives together to ensure uniform mixing. The TMR feed is then delivered to the feeding area using appropriate equipment. During feeding, dairy cows exhibit picky eating behavior due to different feed preferences, pushing unwanted feed out of the feeding area. This affects the cows' nutrient absorption, leading to a decrease in milk yield and quality. Therefore, a feed-pushing robot is used to push the feed back to the feeding area. However, in related technologies, stacking robots are difficult to maintain due to the confined space of the surrounding cylindrical enclosure. Utility Model Content

Detailed Implementation
[0036] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0037] Figure 1 This is a three-dimensional structural diagram of the pusher robot body according to an embodiment of the present utility model; Figure 3 This is a three-dimensional structural diagram of the pusher cylinder according to an embodiment of the present utility model. Figure 1 and Figure 3 As shown, the pusher robot of the present invention, an exemplary embodiment, includes a main body and a pusher cylinder surrounding the main body, with the pusher cylinder rotatably mounted on the main body. The main body includes a walking chassis 10, a first base plate 30, and a plurality of rollers 43. The first base plate 30 is mounted above the walking chassis 10 via a plurality of columns 41. Each roller 43 is rotatably mounted on the outside of the corresponding column 41. The pusher cylinder includes a cylinder 60 and a frame structure 61 supported within the cylinder 60, with the frame structure 61 rotatably mounted on the first base plate 30. An annular guide rail 62 is also provided on the inner wall of the cylinder 60, and each roller 43 is attached to the inner wall surface of the guide rail 62. The main body also includes a drive device 21 located below the first base plate 30, which is connected to the frame structure 61 in a transmission manner.
[0038] In practical applications, the drive device 21 drives the frame structure 61 to rotate on the first base plate 30, and the frame structure 61 drives the cylinder 60 to rotate circumferentially along the body. During the rotation, the outer wall of the cylinder 60 pushes the feed back into the cow's feeding area. Driven by the walking chassis 10, the feeding robot walks along the feeding area, thereby pushing all the feed that has been pushed out of the feeding area back into the feeding area.
[0039] Specifically, the portion of the frame structure 61 located at the top of the cylinder 60 is rotatably positioned above the first base plate 30. The frame structure 61 also includes an annular guide rail 62, which is located on the inner wall of the cylinder 60 and at the center of the cylinder 60 in the vertical direction. Multiple rollers 43 are circumferentially arranged at the center of the body. Specifically, the rollers 43 are rotatably mounted on a column 41, which connects the first base plate 30 and the traveling chassis 10. The rollers 43 roll and conform to the inner wall surface of the guide rail 62, thereby allowing the cylinder 60 to rotate smoothly.
[0040] For example, the first base plate 30 and the traveling chassis 10 are generally square in shape, and there are four pillars 41, each pillar 41 being located at a corner of the first base plate 30 and a corner of the traveling chassis 10. Two ear plates 42 are provided on the outer side of the pillar 41, and the rollers 43 are rotatably disposed between the two ear plates 42 via a rotating shaft. It can be understood that the rotating shaft is arranged in the vertical direction.
[0041] Since the columns 41 are distributed along the circumference of the body, the rollers 43 are evenly distributed along the circumference of the body, reducing swaying and ensuring the overall stability of the pusher robot.
[0042] In some implementations, the roller 43 can be a nylon wheel. When the pushing robot is subjected to external impact, the roller 43 can act as a buffer, preventing deformation and enhancing the impact resistance of the robot body.
[0043] Continue as Figure 1 As shown, the main body also includes a battery 13 and a second substrate 20 located between the chassis 10 and the first substrate 30; the second substrate 20 is located in the middle of the column 41; the second substrate 20 has a first clearance opening, the battery 13 is located on the chassis 10, and a portion of the battery 13 is located in the first clearance opening; the first substrate 30 has a second clearance opening 31 opposite to the first clearance opening.
[0044] The battery 13 is a vertically removable battery, which is mounted on the walking chassis 10 and passes through the second substrate 20 through a first clearance opening. Correspondingly, the first substrate 30 also has a second clearance opening 31 through which the battery 13 can pass. On the one hand, mounting the battery 13 on the walking chassis 10 can lower the center of gravity of the entire pushing robot, maintain stability, reduce the impact of external factors on the battery 13, and thus ensure the safety of the battery 13. On the other hand, the vertical battery 13 can be pulled out from the top of the cylinder 60, which is convenient for replacement and provides more operating space compared to the battery replacement technology of the prior art.
[0045] Figure 4 This is a top view structural diagram of the material-pushing robot according to an embodiment of the present utility model. Figure 3 and Figure 4As shown, the frame structure 61 located at the top of the cylinder 60 includes a central disc and six aluminum tubes extending outward in the circumferential direction. The aluminum tubes are supported on a ring, and the ring is supported inside the cylinder 60. This structure can disperse the impact force on the cylinder and stably support the cylinder, allowing it to rotate smoothly.
[0046] Figure 2 This is a side view structural diagram of the material pushing robot according to an embodiment of the present invention. Figure 2 As shown, the main body also includes a first gear 22, a second gear 23 disposed at the center of the first base plate 30, and a vertical rod 32. The second gear 23 is rotatably disposed around the vertical rod 32. The first gear 22 meshes with the second gear 23. The frame structure 61 is disposed on the second gear 23. The first gear 22 is disposed on the output shaft of the drive device 21. The diameter of the first gear 22 is smaller than the diameter of the second gear 23.
[0047] The central disc of the frame structure 61 is fixed above the second gear 23 by a ring. The second gear 23 is rotatably mounted on the periphery of the upright 32, which is fixed at the center of the first base plate 30. The drive device 21 can be located below the first base plate 30, for example, on the second base plate 20. Its output shaft passes through the first base plate 30 and is equipped with a first gear 22. The first gear 22 meshes with the second gear 23, thereby transmitting power to the second gear 23, which in turn causes the entire frame structure 61 and cylinder 60 to rotate. For example, the diameter of the first gear 22 is smaller than the diameter of the second gear 23. The gear transmission can reduce speed and increase torque to meet heavy-duty operations, improve transmission accuracy and reduce error accumulation, achieve smooth operation and reduce noise and vibration, and has high reliability, simple and durable structure, small size and strong adaptability, making it suitable for various environments and loads.
[0048] For example, the drive unit 21 can be a Z5BLD motor.
[0049] For example, the pole 32 can be a hollow pole with an internal hollow cavity that penetrates the first substrate, providing a channel for the cables of electronic devices.
[0050] Figure 5 This is a front view structural diagram of a material-pushing robot according to an embodiment of the present utility model. Figure 2 and Figure 5 As shown, the pushing robot also includes a dust cover on the pushing cylinder. The dust cover includes a base 51 and a cover body 52 hinged to the base 51. The base 51 includes an annular base and a crossbeam located inside the base. The crossbeam is fixed on the upright 32. The diameter of the base is the same as the diameter of the cylinder 60.
[0051] Due to the dusty working environment of the pushing robot and to prevent rainwater from corroding the internal components of the cylinder 60, a dust cover is installed above the rotating cylinder 60 to avoid these problems. Specifically, the crossbeam supported inside the base can be fixedly mounted on the upright 32. During the rotation of the cylinder 60, the base remains stationary, thus decoupling the dust cover from the rotation of the cylinder 60. The dust cover only translates with the chassis 10 and does not participate in the rotation of the cylinder 60. Therefore, the cylinder 60 and the dust cover constitute two independent motion systems. When at least one ultrasonic rangefinder, such as a lidar, is installed on the top of the cover 52 to measure the distance between the material and the vehicle body, the pushing robot can accurately plan its trajectory using SLAM (Simultaneous Localization and Mapping) algorithm based on radar echo data. Furthermore, during movement, the rotation frequency of the cylinder is not affected by adjustments to the robot's posture or external interference, ensuring the stability and autonomy of the pushing action.
[0052] For example, the cover 52 is a spherical crown-shaped component that can be opened and closed within a range of 0° to 90° via a hinge, thereby allowing for convenient and quick maintenance of the components inside the robot body from the top.
[0053] In some embodiments, the pusher cylinder also includes a plurality of rubber strips 63 surrounding the bottom outer wall of the cylinder body 60, the rubber strips 63 having free ends spaced apart from the cylinder body 60.
[0054] For example, the rubber strip 63 can be a rubber strip or a brush ring, which can cover the gap between the cylinder and the ground. During the feeding process, the rotation of the cylindrical body 60 acts directly on the feed through friction, pushing the feed to move in a predetermined direction. The brush ring utilizes its contact with the material and the ground to perform cleaning and sorting functions. It can not only clean up debris at the bottom and prevent material accumulation from causing feeding difficulties, but also use the combing action of the bristles to organize the material to a designated position, optimize material distribution, and improve feeding efficiency. At the same time, the brush ring can remove small obstacles on the robot's travel path, ensuring smooth robot movement.
[0055] Specifically, there can be multiple rubber strips 63, such as three or four. The ends of the rubber strips 63 along the rotation direction of the cylinder 60 do not adhere to the bottom outer wall of the cylinder 60, but detach from the cylinder 60 to form free ends. These free ends can better play the role of propelling feed.
[0056] In some embodiments, the chassis 10 includes two drive motors, two drive wheels 11 arranged in an equilateral triangle, and one driven wheel 12; each drive wheel 11 is connected to the corresponding drive motor.
[0057] The layout of two driving wheels 11 and one driven wheel 12 arranged in an equilateral triangle can effectively balance the vehicle's center of gravity, giving the chassis strong anti-roll performance and improving driving stability. Each driving wheel 11 is driven by an independent drive motor, enabling flexible steering and optimizing the turning radius.
[0058] For example, the drive wheel 11 and the corresponding drive motor are fastened to the chassis 10 with four bolts. When disassembling the drive wheel 11 and the drive motor, only four bolts need to be removed to achieve quick separation, simplifying the assembly process, reducing assembly time and process complexity, reducing production costs, and providing convenience for subsequent maintenance, thereby reducing maintenance costs and time costs.
[0059] In some embodiments, the second substrate 20 is provided with multiple protective shells for housing electronic components. These electronic components may include motor drivers, electronic buzzers, MOSFETs, small human-machine interface screens, etc. These electrical control components are housed in waterproof protective shells to prevent moisture and dust ingress that could lead to malfunctions. Furthermore, arranging the electronic components between the first substrate 30 and the second substrate 20 solves the problems of messy electrical wiring, difficult wiring, high costs, and difficulty in maintenance.
[0060] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
