[0014] 1. This utility model, by installing a combined platform on top of the chassis assembly, utilizes its structural design to give the robot flexibility and stability. The design of the combined platform allows for the installation of various feeding devices or tools to meet different operational needs. The inclusion of an electric rotary seat enables the combined platform to rotate 360 ​​degrees, further improving the flexibility and accuracy of feeding. At the same time, the structural design of the chassis assembly enhances the robot's stability and load-bearing capacity. The welded connection between the counterweight and the stabilizing platform, as well as the inclusion of a buffer seat, effectively reduces vibration and swaying during robot movement, ensuring the stability and accuracy of feeding. The matching design of the docking groove and the support frame allows the combined platform to be firmly installed on the chassis assembly, further improving the overall structural strength of the robot and facilitating later disassembly and maintenance. In addition, the chassis assembly, combined platform, moving wheel set, and protective components adopt a relatively modular structure, which facilitates the replacement or repair of each component individually, reducing operating costs and improving maintenance efficiency. This makes the four-wheeled omnidirectional composite robot for feeding flexible and stable, able to meet different operational needs, while improving the robot's safety and practicality.

[0015] 2. The design of the mobile wheel assembly in this utility model enables the robot to move flexibly in various complex environments. The buffer posts allow the electric self-propelled wheels to maintain the robot's stability and mobility when encountering obstacles, and effectively absorb the impact and vibration during the robot's movement, protecting the electric self-propelled wheels and electric joints, extending their service life, and ensuring good passability and stability under different terrain conditions. The fixed connection between the electric joints and the fixed seat, and the movable installation of the fixed seat on the side surface of the counterweight seat, allow the mobile wheel assembly to be adjusted within a certain range of angles relative to the chassis assembly. This allows for adjustment of the tilt height of the entire mobile wheel assembly according to actual needs, adapting to different ground conditions, and further enhancing the robot's adaptability and flexibility. In addition, the electric self-propelled wheels are made of wear-resistant materials, which have excellent wear resistance and corrosion resistance, extending their service life and reducing maintenance costs. The movable connection between the fixed seat and the counterweight seat allows the mobile wheel assembly to maintain stability while also having a certain degree of elasticity, effectively mitigating the impact forces that the robot may experience during movement, further improving the robot's stability and durability.

[0016] 3. The protective components of this utility model further enhance the safety and stability of the robot. The buffer baffle and buffer rod can buffer the robot when it encounters a collision, effectively preventing damage to the robot during the collision and protecting the robot's key components. The docking seat is movably installed on one side of the buffer seat, so that the protective components can be firmly installed on the chassis assembly, while facilitating disassembly and replacement in the future. As a result, the device structure has the advantages of compact structure, flexibility and stability, strong load-bearing capacity, good adaptability and safety and reliability. It can be widely used in field operations, logistics and transportation and other fields, bringing convenience to production and life. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1 to 5 As shown, a four-wheeled omnidirectional composite robot for feeding includes a chassis assembly 1 and a combined platform 2. The combined platform 2 is mounted on the top of the chassis assembly 1, and the moving wheel sets 3 are symmetrically mounted on the left and right sides of the bottom of the moving wheel sets 3. Protective components 4 are mounted on both the front and rear ends of the chassis assembly 1. The combined platform 2 includes a support frame 201, an electric rotary seat 202, and a combined seat 203. The electric rotary seat 202 is mounted in the middle of the top of the support frame 201, and the combined seat 203 is mounted on the top of the electric rotary seat 202. The inner surface structure of the docking groove 104 matches the outer surface structure of a section of the bottom of the support frame 201, and two sets of holes for bolt installation are provided at the connection between the support frame 201 and the docking groove 104. The combined base 203 adopts a flange structure. The chassis assembly 1 includes a counterweight base 101, a stabilizing platform 102, a buffer base 103, and a docking groove 104. The stabilizing platform 102 is installed on the top of the counterweight base 101, and the buffer base 103 is horizontally installed at both the front and rear ends of the top of the stabilizing platform 102. The top surface of the stabilizing platform 102 is symmetrically provided with docking grooves 104. The counterweight base 101 and the stabilizing platform 102 are welded together, and the buffer base 103 and the stabilizing platform 102 are also welded together. The design of the combined base 2 allows for the installation of various feeding devices or tools to meet different operational needs. The electric rotary base 202 enables the combined base 203 to rotate 360 ​​degrees, further improving the flexibility and accuracy of feeding.

[0025] like Figures 1 to 5As shown, the mobile wheel assembly 3 includes a buffer post 301, an electric self-propelled wheel 302, an electric joint 303, and a fixed seat 304. One end of the buffer post 301 is connected to the electric self-propelled wheel 302, and the other end of the buffer post 301 away from the electric self-propelled wheel 302 is connected to the electric joint 303. The other end of the electric joint 303 away from the buffer post 301 is connected to the fixed seat 304. The electric joint 303 and the fixed seat 304 are fixedly connected. Holes for bolt installation are provided at the four opposite corners of the fixed seat 304. The fixed seat 304 is movably mounted on the side surface of the counterweight 101. The buffer post 301 enables the electric self-propelled wheel 302 to maintain the robot's stability and mobility when encountering obstacles, and effectively absorbs the impact and vibration during the robot's movement. The electric joint 303 allows the mobile wheel assembly 3 to adjust its angle relative to the chassis assembly 1 within a certain range, thereby adjusting the tilt height of the entire mobile wheel assembly 3 according to actual needs and adapting to different ground conditions.

[0026] like Figures 1 to 5 As shown, the protective component 4 includes a buffer baffle 401, a buffer rod 402, and a docking seat 403. Two sets of buffer rods 402 are horizontally installed on the side of the buffer baffle 401 near the chassis assembly 1, and a docking seat 403 is installed on the end of the buffer rod 402 away from the buffer baffle 401. The docking seat 403 is movably installed on one side of the buffer seat 103, and the buffer rod 402 and the docking seat 403 are fixedly connected. The buffer baffle 401 and the buffer rod 402 can play a buffering role when the robot encounters a collision, effectively preventing damage to the robot during the collision and protecting the robot's key components. The docking seat 403 is movably installed on one side of the buffer seat 103, so that the protective component 4 can be firmly installed on the chassis assembly 1, and at the same time, it is convenient for later disassembly and replacement.

[0027] In summary, as Figures 1 to 5 As shown, the four-wheeled omnidirectional composite robot used for feeding first places the chassis assembly 1 stably in the working area. The stability of the robot during operation is ensured by the sturdy structure of the counterweight seat 101 and the stabilizing platform 102. Then, the combined platform 2 is bolted to the docking groove 104 on the chassis assembly 1 through the hole structure at the bottom of the support frame 201, so as to achieve the firm installation of the combined platform 2. The start of the electric rotary seat 202 allows the combined platform 203 to rotate flexibly and adjust the feeding direction according to the operation requirements. The feeding equipment required for the operation can be installed on the combined platform 203 to facilitate subsequent precise feeding operations.

[0028] At the same time, the moving wheel set 3 on the chassis assembly 1 is activated, and the electric self-propelled wheel 302 moves according to the preset path or operation command. When encountering uneven ground or obstacles, the buffer column 301 effectively absorbs the impact and keeps the robot moving smoothly. The electric joint 303 adjusts the angle of the moving wheel set 3 according to the terrain changes to ensure that the robot can maintain good passability and stability in various complex environments.

[0029] During operation, the protective component 4 plays a crucial role. The combination of the buffer baffle 401 and the buffer rod 402 can effectively disperse the impact force when the robot encounters an accidental collision, protecting the robot's key components from damage. At the same time, the movable connection design between the docking seat 403 and the buffer seat 103 not only ensures the stable installation of the protective component 4, but also facilitates its disassembly and maintenance in the future.
