Description

Technical Field

[0001] This utility model relates to the field of grain warehouse robot technology, and in particular to a grain warehouse robot that is easy to walk. Background Technology

[0002] Grain silo robots are used to address the safety risks associated with manual entry into grain silos. They can be remotely controlled to prevent employees from being submerged in grain. These robots can move freely across the grain without getting stuck, and can also smooth out uneven grain, keeping the grain silo clean. Furthermore, they can autonomously take samples within the grain silo, randomly selecting samples for collection.

[0003] Grain storage robots need to move on grain within the storage silo. The surface of the grain may have uneven areas, and the outer surface of the robot's chassis can easily come into contact with these uneven grains, potentially causing collisions. Currently, the chassis width of grain storage robots on the market is the same from top to bottom. This type of robot has a large collision area with the grain, resulting in greater impact force and weak force dissipation, making it prone to tipping over. Utility Model Content

[0004] The main purpose of this invention is to propose a convenient walking grain warehouse robot, which aims to reduce the impact of grain on the robot's chassis.

[0005] To achieve the above objectives, the present invention proposes a convenient walking grain silo robot, comprising:

[0006] The main body includes the top cover and chassis assembled as one unit;

[0007] A control panel assembly is disposed inside the main body;

[0008] A drive component, connected to the main body, is used to drive the main body to move;

[0009] The chassis includes a compartment, the width of which decreases in the direction away from the top cover.

[0010] In one embodiment, the silo body has a two-tier structure, including a first tier and a second tier arranged sequentially from top to bottom. The outer wall of the first tier is an inclined surface, and the outer wall of the second tier is a curved surface.

[0011] In one embodiment, the chassis further includes two side wings connected to the cargo body, with the two side wings respectively disposed on both sides of the cargo body.

[0012] In one embodiment, the bottom wall of the side wing is higher than the bottom wall of the cargo box.

[0013] In one embodiment, the two side wings are located at the middle of the main body.

[0014] In one embodiment, the chamber body and the side wings are integrally injection molded.

[0015] In one embodiment, the device further includes two handles, which are respectively disposed on both sides of the compartment.

[0016] In one embodiment, the handle includes a handle bracket and a handle glove, the handle glove being fitted onto the handle bracket.

[0017] In one embodiment, the inner wall of the glove is provided with a plurality of positioning protrusions, and the handle bracket includes positioning grooves that are adapted to the protrusions.

[0018] In one embodiment, the grain warehouse robot further includes a strip-shaped signal indicator assembly, which is connected to the control board assembly.

[0019] The lower width of the chassis of this utility model is smaller than the upper width. Because the lower width is smaller, the probability of the chassis coming into contact with the grain is lower during movement. Even if it does come into contact with the grain, the resistance from the grain is smaller due to the reduced contact area. Therefore, the robot walks more conveniently and the probability of the grain silo robot tipping over is reduced. Attached Figure Description

[0034] Grain silo robots need to operate inside grain silos for extended periods. Because of the grain inside, the surface of the grain may be uneven, and the robot's chassis is prone to contact with this uneven grain, resulting in collisions. Currently, grain silo robots on the market have chassis of uniform width, or a chassis where the upper part is wider than the lower part. This type of structure results in a larger contact area with the grain, leading to greater impact force and weak force dissipation, making the robot prone to tipping over. Therefore, this application proposes a more convenient, mobile grain silo robot.

[0035] Please refer to Figures 1 to 3 As shown, this application proposes a convenient walking grain silo robot, including a main body 1, a control board assembly 2, and a drive assembly 3. The control board assembly 2 is disposed inside the main body 1 and is used to control the normal operation of the grain silo robot and to control the grain silo robot to perform different tasks, such as leveling the grain surface in the grain silo and performing random sampling. The drive assembly 3 is connected to the main body 1 and electrically connected to the control board assembly 2. The drive assembly 3 receives signals from the control board assembly 2 and drives the main body 1 to move forward, backward, and turn, thereby completing the tasks of the grain silo robot.

[0036] In this embodiment, the main body 1 includes an upper cover 11 and a chassis 12. The upper cover 11 is disposed above the chassis 12, and the upper cover 11 and chassis 12 are assembled to form a cavity structure with internal accommodating space to accommodate other components. A drive assembly 3 is disposed below the main body 1, and a portion of the drive assembly 3 may be disposed inside the main body 1. The chassis 12 includes a storage compartment 121, the width of which decreases in the direction away from the upper cover 11. It should be noted that the length direction of the storage compartment 121 is the same as the forward direction of the grain storage robot.

[0037] When the grain silo robot walks on the grain surface inside the silo, the distance between the chassis 12 and the grain surface is very close, and the grain surface is uneven. Therefore, the chassis 12 inevitably bumps into the grain during movement. The chassis 12 of this application has a long and narrow silo body 121, which reduces air resistance during movement. Furthermore, the width of the silo body 121 gradually decreases in the direction away from the top cover 11, that is, the width of the lower end of the silo body 121 is smaller than the width of the upper end. The smaller width at the lower end reduces the probability of the chassis 12 contacting the grain during movement. Even if it does contact the grain, the reduced contact area results in less resistance from the grain, making the robot's movement more convenient and reducing the probability of the grain silo robot tipping over.

[0038] Please refer to Figure 2 As shown, the storage body 121 comprises a two-tiered structure, namely a first tier 122 and a second tier 123, with the first tier 122 positioned above the second tier 123. The outer wall of the first tier 122 is inclined, while the outer wall of the second tier 123 is curved. In this embodiment, the width of the chassis 12 does not decrease uniformly from top to bottom; the width of the chassis 12 exhibits two decreasing trends. The chassis 12 has a first tier 122 and a second tier 123. The first tier 122 is located far from the bottom of the chassis 12, therefore it does not essentially contact the grain below, hence the inclined outer wall of the first tier 122. The second tier 123 is located at the bottom of the chassis 12, thus it more easily contacts the grain surface, hence the curved outer wall of the second tier 123. The curved surface increases uniformity and reduces the resistance generated when the chassis 12 contacts the grain.

[0039] Please refer to Figure 4 As shown, the chassis 12 also includes two side wings 124, which are respectively located on both sides of the cargo box 121.

[0040] Specifically, the side wings 124 are perpendicular to the silo body 121, forming a cross shape, with the two side wings 124 located on the left and right sides of the silo body 121 respectively. The two side wings 124 both expand the width of the chassis 12 to accommodate more components and reduce material usage. For example, if the chassis 12 of the grain silo machine adopts a rectangular structure, although the rectangular structure of the chassis 12 provides more internal space, it would require more raw materials, increasing material costs. Furthermore, the two side wings 124 of this application are symmetrical about the central axis of the silo body 121. The symmetrical side wings 124 on both sides also act as balance arms, greatly increasing the overall balance of the grain silo robot, thereby improving its balance performance during operation and reducing the possibility of the grain silo robot tipping over.

[0041] Please refer to this again. Figure 2As shown, the bottom wall of the side wing 124 is higher than the bottom wall of the hopper body 121. Although the side wall can increase the balance of the grain hopper robot, the side wing 124 also indirectly increases the width of the hopper body 121. To prevent the side wing 124 from contacting the grain, it is positioned above the hopper body 121, meaning the bottom wall of the side wing 124 is higher than the bottom wall of the hopper body 121. In this embodiment, two side wings 124 are used to increase the balance of the chassis 12, and positioning the side wings 124 above the hopper body 121 reduces the possibility of the side wing 124 contacting the grain. The specific value by which the bottom wall of the side wing 124 is higher than the bottom wall of the hopper body 121 can be set according to actual conditions.

[0042] Please refer to this again. Figure 4 As shown, in an optional embodiment, two side wings 124 are positioned at the center of the silo body 121. Positioning the two side wings 124 at the center of the silo body 121 creates a horizontally and vertically symmetrical "cross-shaped" structure for the chassis 12, structurally increasing the overall balance of the grain silo robot. Since the grain silo robot not only moves forward and backward within the silo but also turns, the horizontally and vertically symmetrical structure of the silo body 121 ensures the stability of the grain silo robot during movement and reduces the probability of it tipping over.

[0043] In an optional embodiment, the side wings 124 and the housing 121 are integrally injection molded. This application also integrally injection molds the chassis 12. Integral molding of the chassis 12 reduces the number of parts. This reduction in parts facilitates material management, significantly simplifies material management during production, reduces the probability of production errors, and provides greater convenience for material management. The reduction in materials also reduces the number of molds, thus significantly lowering mold costs. Furthermore, using integral injection molding combines multiple parts into one, reducing subsequent assembly steps and lowering labor assembly costs.

[0044] Please refer to Figure 3As shown, in this embodiment, the drive assembly 3 includes two drive units 31, which are respectively connected to both ends of the side wing 124. Specifically, each drive unit 31 includes a motor 311, a reducer 312, and a drive wheel 313. The motor 311 is driven by the reducer 312, and the reducer 312 is driven by the drive wheel 313. The motor 311 is located at the end of the side wing 124 away from the silo body 121, and the reducer 312 is located below the motor 311. During operation, the motor 311 receives a signal from the control board assembly 2 and starts up. The reducer 312 reduces the rotational speed and increases the torque to ensure that the grain silo robot can move stably on the grain surface. The drive wheel 313 is in direct contact with the grain surface and partially sinks into the grain surface during rotation, providing stable power for the grain silo robot to move forward. In this embodiment, a motor 311 is provided at the ends of both side wings 124. The dual motors 311 provide power to the entire device, resulting in stronger power and easier turning operations. When turning, the speed difference between the two motors 311 can be achieved.

[0045] The drive wheel 313 is a spiral wheel. When the spiral wheel is initially placed on the grain surface, the grain bin robot only sinks a small amount into the grain under its own gravity. After the motor 311 is started, the depth of the spiral wheel sinking into the grain will increase until it reaches a stable state, and it will maintain this depth to perform operations such as moving forward, backward, and turning.

[0046] Please refer to Figure 2 , Figure 3 and Figure 5 As shown, in an optional embodiment, the grain silo robot of this application further includes two handles 4, which are respectively disposed on both sides of the width direction of the silo body 121. Each handle 4 includes a handle bracket 41 and a glove 42, with the glove 42 fitted onto the handle bracket 41.

[0047] Specifically, to facilitate users in handling the grain silo robot of this application, two handles 4 are also provided on the grain silo robot. The two handles 4 are located on both sides of the width direction of the silo body 121 of the chassis 12, and are symmetrically arranged. The grain silo robot of this application has two handles 4, allowing users to handle the grain silo robot more stably and conveniently. Each handle 4 includes a handle bracket 41 and a handle glove 42. The handle bracket 41 includes a first arm 411 and two second arms 412 connected together, with both ends of the first arm 411 connected to the second arms 412. The ends of the two second arms 412 are inserted into the chassis 12 for fixation. The handle glove 42 is fitted onto the first arm 411. The handle glove 42 increases the friction generated when the user handles the robot, ensuring stable handling and preventing slippage and falls to the ground, thus indirectly protecting the grain silo robot. In a preferred embodiment, the second arm 412 includes a third arm 4121 and a fourth arm 4122 connected together, with an obtuse angle between them. During installation, the third arm 4121 is vertically inserted into the chassis 12, and the fourth arm 4122 is extended outward. This structure can further reduce the force required for the user to handle the grain bin robot. In some embodiments, the handle bracket 41 is made of a metal tubular component, which is bent to form the above-mentioned shape. The metal tubular component has good mechanical properties, preventing the handle bracket 41 from breaking.

[0048] Please refer to Figure 5 As shown, in an optional embodiment, the handle bracket 41 includes multiple positioning grooves 413, and the inner wall of the glove 42 is provided with multiple positioning protrusions 421. Specifically, the outer surface of the first arm 411 is recessed inward to form multiple positioning grooves 413, which are spaced apart. The glove 42 is fitted onto the first arm 411, and the inner wall of the glove 42 is provided with multiple positioning protrusions 421, the position and number of which are adapted to the positioning grooves 413. During installation, the positioning protrusions 421 are inserted into the positioning grooves 413. By setting the positioning protrusions 421 and the positioning grooves 413, the position of the glove 42 on the surface of the first arm 411 is fixed, preventing the glove 42 from sliding when the user picks up and puts down the grain silo robot. This avoids the possibility of the glove 42 slipping and causing the grain silo robot to fall, thus increasing the protection of the grain silo robot. The glove 42 is made of rubber or silicone material with a certain degree of elasticity. The handle glove 42, made of rubber or silicone, can increase friction to ensure stable gripping and placing by the user; furthermore, the elasticity of rubber or silicone makes it easy to install the handle glove 42 on the outside of the handle bracket 41.

[0049] Please refer to Figures 6 to 8As shown, in an optional embodiment, the grain silo robot of this application further includes a strip-shaped signal indicator assembly 5. The strip-shaped signal indicator assembly 5 is disposed between the upper cover 11 and the chassis 12, and is exposed to the outside, allowing the user to see the signal indicator assembly 5 from the outside, facilitating the user's confirmation of whether the grain silo robot is operating normally. The signal indicator assembly is located at the front end of the silo body 121 for easy observation by the user.

[0050] The signal indicator assembly 5 includes a light strip 51 and a light guide structure 52. The light guide structure 52 is made of optical materials, such as acrylic resin, polycarbonate, epoxy resin, etc. A ring of recessed cavities 521 is provided on the light guide structure 52. The depth of the recessed cavity 521 is slightly greater than the width of the light strip 51. The light-incident surface 522 inside the recessed cavity 521 is smooth, flat, and uniform, and matches the LED beads on the light strip 51 to ensure efficient coupling and light capture. The light-incident surface 522 of the light guide structure is parallel to the surface of the light strip 51, and the input end of the light guide is close to the LED beads to improve the coupling efficiency in the light path. The distance between the LED beads and the light-incident surface 522 is maintained at approximately 0.5 mm.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
