Description

Technical Field

[0001] The present invention relates to the technical field of granary robots, and in particular to an intelligent granary robot. Background Art

[0002] The granary robot is used to solve the safety risks of manual entry into the granary. It can be remotely controlled to prevent employees from being drowned in grain. The granary robot can move back and forth on the grain without getting stuck in it, and can also tidy up uneven grain to keep the granary clean. In addition, the granary robot can also autonomously sample in the granary and randomly select samples for sampling.

[0003] The granary robot on the market includes a transmission shaft and a spiral wheel, wherein the spiral wheel has a hollow shaft portion and spiral blades integrally arranged on the outer wall of the hollow shaft portion. There are currently two matching modes of the transmission shaft and the spiral wheel.

[0004] 1. The transmission shaft is a flat shaft, and a hole adapted to the flat shaft is arranged in the spiral wheel.

[0005] Second, a very long keyway is set on the transmission shaft, a key is installed, and a groove matching the key is set inside the hollow shaft.

[0006] Both solutions will result in a smaller diameter of the hollow shaft of the spiral wheel. When the outer diameter of the spiral wheel is fixed, the greater the height of the spiral blade, the lower the mechanical strength of the spiral wheel. When used for a long time, the spiral blade is easily damaged after being under pressure for a long time. In addition, the diameter of the hollow shaft is small.

[0043] Please refer to Figure 1-Figure 5 As shown, an intelligent granary robot provided by an embodiment of the present application includes a main body 1, a control panel assembly 2 and two drive assemblies 3. The control panel assembly 2 is arranged inside the main body 1, and the drive assembly 3 is installed on the main body 1. The drive assembly 3 includes a motor 31, a transmission shaft 32 and two spiral wheel assemblies 33. The motor 31 is connected to the transmission shaft 32 in a transmission manner, and the two spiral wheel assemblies 33 are connected to the transmission shaft 32 in a transmission manner, that is, the transmission shaft 32 is driven to rotate by the rotation of the motor 31, and the rotation of the transmission shaft 32 drives the spiral wheel assembly 33 to rotate to run on the grain surface. In this embodiment, the two drive assemblies 3 are arranged at intervals below the main body 1, and the main body 1 is supported and driven to move by the drive assembly 3. Each drive assembly 3 has two spiral wheel assemblies 33, and the two spiral wheel assemblies 33 are driven by a transmission shaft 32, and the two spiral wheel assemblies 33 are coaxially arranged on the transmission shaft 32 at intervals.

[0044] The control panel assembly 2 is electrically connected to the motor 31, and the control panel assembly 2 is used to control the granary robot to intelligently complete the preset task under the preset program. For example, the preset task of the intelligent granary robot is to level the grain surface. After starting, the intelligent granary robot can walk along the preset route and complete the task of leveling the grain during the walking process. For another example, the preset task of the intelligent granary robot of the present application is to perform random sampling. After receiving the signal, the intelligent granary robot starts the motor 31 to drive the main body 1 to move to the corresponding position and then perform sampling.

[0045] Please refer to Figure 2 , Figure 6 and Figure 7As shown, the spiral wheel assembly 33 includes a spiral wheel 331 and two sleeves 332, and the two sleeves 332 are respectively arranged at both ends of the spiral wheel 331. The spiral wheel 331 includes a hollow shaft 3311 and a spiral blade 3312 arranged around the outer side of the hollow shaft 3311. The transmission shaft 32 is axially arranged in the hollow shaft 3311, the transmission shaft 32 is transmission-connected with the sleeve 332, and the sleeve 332 is transmission-connected with the spiral wheel 331. In this embodiment, the number of spiral wheels 331 is set to four, the number of transmission shafts 32 is two, and the number of motors 31 is two. Among them, two spiral wheels 331 are sleeved on one transmission shaft 32, and the transmission shaft 32 is driven to rotate by one motor 31, thereby driving the two spiral wheels 331 to rotate. The other two spiral wheels 331 are sleeved on another transmission shaft 32, and the transmission shaft 32 is driven to rotate by another motor 31, so as to drive the two spiral wheels 331 to rotate. The present application is driven by two motors 31, with sufficient power and stable travel.

[0046] The drive assembly 3 of the intelligent granary robot provided by the present application adds a shaft sleeve 332, which is driven to rotate by the transmission shaft 32 during operation, and then the spiral wheel 331 is driven to rotate by the shaft sleeve 332. Due to the existence of the shaft sleeve 332, the diameter of the hollow shaft of the spiral wheel 331 of the present application can be set larger, the diameter of the hollow shaft increases, and the strength of the spiral blades 3312 on the two spiral wheels 331 increases, so the spiral blades 3312 of the spiral wheel 331 are less susceptible to damage, which can increase the service life of the spiral blades 3312; in addition, since there is a large hollow space in the cooperation between the hollow shaft and the shaft sleeve 332, the overall weight of the present application will be reduced, and the energy used to drive the operation of the granary robot can also be reduced, which has the effect of energy saving and environmental protection.

[0047] Please refer to Fig.10 As shown, in this embodiment, the inner diameter of the hollow shaft 3311 is within the range of 30mm-60mm. The inner diameter of the hollow shaft 3311 can be selected to be 45mm, the outer diameter can be selected to be 55mm, and the diameter of the transmission shaft 32 is 14mm. The gap between the hollow shaft 3311 and the transmission shaft 32 can be used to accommodate the shaft sleeve 332. The present application uses the shaft sleeve 332 to drive and connect the transmission shaft 32 and the spiral wheel 331 to increase the outer diameter of the hollow shaft 3311 on the spiral wheel 331, thereby improving the mechanical strength of the spiral blade 3312.

[0048] Please refer to Figure 8-Figure 10As shown, in an optional embodiment, the sleeve 332 includes a shaft body 3321 and a flange 3322, and the flange 3322 is connected to one end of the shaft body 3321. The shaft body 3321 penetrates into the hollow shaft 3311 of the spiral wheel 331, and the flange 3322 abuts against the end of the hollow shaft 3311. The present application sets a sleeve 332 at each end of the spiral wheel 331, and the shaft bodies 3321 of the two sleeves 332 are inserted into the hollow shaft 3311, and then the two ends of the hollow shaft 3311 are covered by the setting of the flange 3322 to form a complete integral spiral wheel assembly 33, and the mechanical strength at the position of the two spiral wheels 331 is higher. It can be understood that the inner diameter of the hollow shaft 3311 is equal to the outer diameter of the shaft body 3321 to ensure the fit between the sleeve 332 and the hollow shaft 3311. In a preferred embodiment, the ends of the spiral blades protrude outside the hollow shaft to form a plurality of clamping parts 3314, and the clamping parts 3314 clamp the flange edges. The provision of the clamping parts 3314 facilitates accurate positioning during assembly by the user, and can also protect the shaft sleeve 332, reduce the friction of the food on the periphery of the shaft sleeve 332, and thus reduce the damage to the shaft sleeve 332.

[0049] Please refer again Fig. 9 As shown, in this embodiment, at least two protruding blocks 3323 are also provided outside the shaft body 3321, and at least two first grooves 3313 are provided on the inner wall of the hollow shaft 3311. After the sleeve 332 is installed in the hollow shaft 3311, multiple protruding blocks 3323 are respectively inserted into the first grooves 3313. To ensure the stability of the transmission cooperation between the sleeve 332 and the spiral wheel 331. The number of protruding blocks 3323 can be set to two, and the two protruding blocks 3323 are 180 degrees apart to make the force symmetrical. The protruding blocks 3323 can also be set to three, and the angles between the three protruding blocks 3323 are all 120. The number of protruding blocks 3323 here can be set according to actual needs, and the number of first grooves 3313 is the same as the number of protruding blocks 3323.

[0050] See also Fig.10 As shown, in an optional embodiment, the first groove 3313 is provided on the end surface of the hollow shaft 3311, that is, the first groove 3313 extends from the end surface of the hollow shaft 3311 to the inside of the hollow shaft 3311. The first groove 3313 is provided corresponding to the root of the spiral blade 3312, and the thickness of the spiral blade 3312 tends to increase in the direction toward the root.

[0051] Specifically, the first groove 3313 extends from the end surface of the hollow shaft 3311 to the inside of the hollow shaft 3311 to facilitate the installation of the sleeve 332. During installation, the protruding block 3323 on the shaft body 3321 is directly aligned with the first groove 3313 in the hollow shaft 3311, and then the shaft body 3321 of the sleeve 332 is inserted into the hollow shaft 3311 until the flange edge 3322 of the sleeve 332 abuts against the end surface of the hollow shaft 3311. The first groove 3313 is set corresponding to the root of the spiral blade 3312 to ensure the mechanical properties of the protruding block 3323 and the first groove 3313. The wall thickness at the root of the spiral blade 3312 is large, and the first groove 3313 is set here, which increases the mechanical strength of the spiral wheel, avoids the probability of damage to the first groove 3313 after long-term use, and ensures that the sleeve 332 and the spiral wheel 331 can be stably transmitted for a long time. The thickness of the spiral blade 3312 increases in the direction toward the root, that is, the thickness of the spiral blade 3312 increases from the side away from the hollow shaft 3311 to the side close to the hollow shaft 3311. This structure further increases the mechanical strength of the spiral blade 3312, ensuring that the spiral wheel 331 does not deform after long-term use, thereby increasing the service life of the spiral wheel 331.

[0052] See also Fig. 9As shown, the shaft body 3321 includes an inner cylinder 3324, an outer cylinder 3325 and a connecting rib 3326. The inner cylinder 3324 and the outer cylinder 3325 are arranged at intervals. The connecting rib 3326 is used to connect the inner cylinder 3324 and the outer cylinder 3325 to increase the mechanical strength of the shaft body 3321. The number, position and thickness of the connecting rib 3326 can be set according to actual conditions and are not limited here. The inner cylinder 3324 has a through hole 3327 and a second groove 3328. The through hole 3327 is used for the transmission shaft 32 to pass through. The second groove 3328 is used to place a key 34. The type of the key 34 is a flat key. It can be understood that the transmission shaft 32 also has a keyway 321. The flat key is arranged in the keyway 321 on the transmission shaft 32 and in the second groove 3328 of the shaft body 3321. The transmission shaft 32 and the sleeve 332 are connected by the key 34. In an optional embodiment, the number of the second grooves 3328 is set to two, and the angle between the two second grooves 3328 is 90. In this embodiment, the number of the raised blocks 3323 is two, the two first grooves at one end of the hollow shaft are 180, and the two first grooves at the other end of the hollow shaft are also 180. The projections of the first grooves at both ends of the hollow shaft on its radial cross section are perpendicular to each other, so the raised blocks at both ends of the hollow shaft are more evenly stressed on the spiral wheel. In order to match the first grooves at both ends of the hollow shaft, the number of the second grooves 3328 is two, and the angle between the two is 90, so that at least one of the two second grooves can be adapted to the key. In other embodiments, the raised blocks can also be set to 4, and the four raised blocks are evenly arranged around the axis of the hollow shaft, which can also make the force on the spiral wheel more even.

[0053] See also Figure 5 As shown, the drive assembly 3 also includes a reducer 35 and a seal 36. The reducer 35 is arranged below the motor 31, and the seal 36 is arranged between the motor 31 and the reducer. The transmission shaft 32 passes through one of the spiral wheel assemblies 33, the reducer 35 and the other spiral wheel assembly 33 in sequence. A plurality of sleeves 37 are arranged between the reducer 35 and the spiral wheel assembly 33, and locking nuts 38 are respectively arranged at both ends of the transmission shaft 32. The spiral assembly also includes two end caps 39, which are installed at both ends of the transmission shaft 32 and cover the locking nuts 38.

[0054] Specifically, the drive assembly 3 also includes a reducer 35 and a seal 36. The motor 31 and the reducer 35 are connected in a transmission manner. The reducer 35 is arranged directly below the motor 31, and a seal 36 is also arranged between the motor 31 and the reducer 35. The seal 36 can increase the sealing performance between the motor 31 and the reducer 35, reduce the corrosion of the gas generated inside the granary to the motor 31, the reducer 35 and the internal parts of the granary robot, and thus improve the service life of the granary robot. The transmission shaft 32 passes through the two spiral wheel assemblies 33 and the reducer 35, and after the reducer 35 decelerates and increases the torque, it drives the spiral wheel assembly 33 to rotate. The two spiral wheel assemblies 33 are arranged on both sides of the reducer 35 to ensure the balance of the power transmission of the reducer 35.

[0055] See also Figure 6-Figure 8 As shown, the drive assembly 3 also includes a plurality of sleeves 37, two locking nuts 38 and two end caps 39. The reducer 35 and the spiral wheel assembly 33 are both sleeved on the transmission shaft 32, and there is a gap between the reducer 35 and the two spiral wheels 331 on both sides thereof. The sleeve 37 is arranged in the gap between the reducer 35 and the two spiral wheels 331, and the sleeve 37 is also sleeved on the transmission shaft 32. Then, the two ends of the transmission shaft 32 are respectively locked with locking nuts 38 to lock the two spiral wheels 331 on both sides of the reducer 35. The two end caps 39 are respectively installed at the two ends of the transmission shaft 32 and cover the locking nuts 38. In this embodiment, during the operation of the granary robot, the sleeves 332 at both ends of the transmission shaft 32 will be impacted by the grain, so an end cap 39 is arranged at each end of the transmission shaft 32 to protect the sleeves 332 at the two ends of the transmission shaft 32. Two positioning columns 391 are provided on the side of the end cap 39 facing the sleeve 332, and two positioning grooves 3329 adapted to the positioning columns 391 are provided on the end surface of the sleeve 332. During installation, the positioning columns 391 are inserted into the positioning grooves 3329, and the end cap 39 is fixed to the sleeve 332 by screws to protect the sleeve 332 and close the through hole 3327 on the sleeve 332 inside.

[0056] In order to improve the sealing and dustproof performance between the spiral wheel 331 and the sleeve 332, the internal components of the spiral wheel 331 are protected to prevent the components of the spiral wheel 331 from being corroded by the gas in the granary. The shaft body 3321 of the sleeve 332 and the hollow shaft 3311 are matched with an interference fit. The openings at both ends of the hollow shaft 3311 are provided with sleeves 332, and the inside of the hollow shaft 3311 is blocked by two sleeves 332. The sleeve 37 between the spiral wheel 331 and the reducer 35 can also block the through hole 3327 on the sleeve 332, and the sleeve 37 cooperates with the end cap 39 to seal and dustproof the two ends of the spiral wheel 331.

[0057] See also Fig.12 and Fig.13 As shown, the main body 1 includes a chassis 12 and an upper cover 11 assembled as one body, a protrusion 111 protrudes upward from the top of the upper cover 11, a protrusion cavity 112 is formed inside the protrusion 111, and an image transmission visual sensor module 4 is arranged in the protrusion cavity 112. The image transmission visual sensor module 4 is used to receive image information from the outside world. The control board assembly 2 receives information from the image transmission receiving module to process and identify the image information, and performs an intelligent task mode under a preset program to complete the task intelligently. For example, the image transmission visual sensor module 4 transmits the image information of the grain surface to the image transmission receiving module. After receiving the image information processed by the image transmission receiving module, the control board assembly 2 determines the position of the uneven grain surface, and starts the motor 31 to move to the position to smooth the grain surface at that position. In this embodiment, the upper cover 11 is arranged above the chassis 12, and the protrusion 111 is arranged on the top of the upper cover 11, and a protrusion cavity 112 is formed in the protrusion, and then the image transmission visual sensor module 4 is installed in the protrusion cavity 112, so that the image transmission visual sensor module 4 is at a higher position and will not be blocked by other parts of the grain silo robot, and can better obtain image information of the surrounding environment. Furthermore, the present application sets the image transmission visual sensor module 4 inside the upper cover, which can better protect the image transmission visual sensor module 4.

[0058] Please refer to Figure 4 , Fig.11 and Fig.12 As shown, in an optional embodiment, the chassis 12 and the upper cover 11 are both cavity structures, the bottom wall of the chassis 12 extends a full circle of the first sealing convex wall 121 to the upper cover 11, and the bottom wall of the upper cover 11 extends a full circle of the second sealing convex wall 113 to the first sealing convex wall 121, and a full circle of the sealing ring 5 is arranged between the first sealing convex wall 121 and the second sealing convex wall 113. The first sealing convex wall 121, the sealing ring 5 and the second sealing convex wall 113 divide the interior of the main body 1 (i.e., the chassis and the upper cover) into two accommodating chambers, namely, the internal sealing protection accommodating chamber 122 and the external buffer chamber 123. The internal sealing protection accommodating chamber 122 can be installed with components such as the control panel assembly 2 to achieve sealing protection of the internal parts. The external buffer chamber 123 is arranged outside the sealing protection accommodating chamber 122. The granary robot will inevitably hit the uneven grain during the movement. The buffer chamber 123 is formed on the periphery of the main body 1, which can play a buffering role and play a buffering protection effect on the internal parts.

[0059] See also Fig.11 , Figure 3 and Fig.14As shown, the granary robot also includes a battery assembly 6. A circle of raised walls 124 is provided at the middle of the chassis 12. The raised walls 124 and the chassis 12 form an installation cavity 125. The battery assembly 6 is fixedly installed in the installation cavity 125. The battery assembly 6 includes a battery pack 61, a shockproof member 62 and a fixing bracket 63. The shockproof member 62 is sleeved outside the battery pack 61. The fixing bracket 63 is provided outside the shockproof member 62 and fixed on the chassis 12.

[0060] Specifically, the granary robot needs to move in the granary for a long time. The surface of the grain in the granary is uneven and the grain surface is soft. Therefore, the granary robot shakes greatly when driving. The battery pack 61 is an important component. The shaking of the battery pack 61 will affect its use effect, and even a fire may occur when the shaking is severe. Therefore, it is necessary to carry out an effective protection design for the battery pack 61. The battery assembly 6 is arranged in the middle position of the chassis 12. The middle position of the chassis 12 includes a raised wall 124. The raised wall 124 extends upward from the bottom of the chassis 12 to form an installation cavity 125. The installation cavity 125 is used to install the battery assembly 6. The battery assembly 6 includes a fixed bracket 63, a shockproof member 62 and a battery pack 61, which are arranged in sequence from the outside to the inside. During assembly, the shockproof member 62 is first placed on the outside of the battery pack 61, and then the battery pack 61 with the shockproof member 62 is placed in the installation cavity 125, and finally the fixing bracket 63 covers the shockproof member 62 and the battery pack 61 from the top, and the battery assembly 6 is fixed to the chassis 12 as a whole through the fixing member. In addition, the present application fixes the battery assembly 6 in the middle of the chassis 12, and the shaking of the middle of the granary robot is minimal, which can also further improve the protection performance of the battery assembly 6.

[0061] See also Figure 3 and Figure 4 As shown, a motor controller assembly 7 is also arranged in the chassis 12, the control board assembly 2 is arranged at the front end of the chassis 12, and the motor controller assembly 7 is arranged at the rear end of the chassis 12, and the motor controller assembly 7 is used to intelligently control the speed of the motor 31 under the control of the control board assembly 2. The motor controller assembly 7 includes an electric adjustment controller 71 and an electric adjustment bracket 72, the electric adjustment bracket 72 is fixed on the chassis 12, and the electric adjustment controller 71 is fixed on the electric adjustment bracket 72.

[0062] In this embodiment, the battery assembly 6 is arranged in the middle of the chassis 12, and the control panel assembly 2 and the motor controller assembly 7 are arranged on the front and rear sides of the battery assembly 6. The battery assembly 6 has the largest weight, and the battery assembly 6 is arranged in the middle of the chassis 12 so that the center of gravity of the granary robot is approximately at the position of the battery assembly 6 to increase the balance of the entire granary robot. There will be a difference in the weight of the control panel assembly 2 and the electric adjustment controller 71, and the electric adjustment bracket 72 can be used to balance so that the center of gravity of the granary robot is approximately in the middle of the chassis 12. In some embodiments, the control panel assembly 2 can also be installed on a control panel bracket to fix the control panel assembly 2 and balance the center of gravity of the entire granary machine. It can be understood that there may be some other components in the chassis 12, and at this time, it is necessary to reasonably distribute them according to the weight of each part so that the center of gravity of the granary robot is approximately at the position of the battery assembly 6.

[0063] Please refer again Figure 3 and Fig.11 As shown, the chassis 12 includes a bin body 12a and two side wings 12b, and the two side wings 12b are respectively connected to both sides of the width of the bin body 12a. The motor 31 is installed at the end of the side wing 12b away from the bin body 12a.

[0064] Specifically, the warehouse body 12a and the side wings 12b are arranged vertically to form a cross shape, and the two side wings 12b are respectively located on the left and right sides of the warehouse body 12a. The side wings 12b on both sides are arranged symmetrically about the central axis of the warehouse body, and the symmetrical side wings 12b play the role of a balancing arm, which greatly increases the balance of the granary robot and reduces the possibility of the granary robot overturning. In this embodiment, the motor 31 is installed at the end of the side wing 12b away from the warehouse body 12a, and the spiral wheel 331 is arranged below the motor 31, which is equivalent to increasing the distance between the spiral wheels 331. Assuming that the two motors 31 are directly arranged on both sides of the warehouse body 12a, the distance between the two spiral wheels 331 is too small, which will affect the stability of the granary robot. The present application adds two side wings 12b, and sets the drive assembly 3 at the end of the side wing 12b to increase the stability of the granary robot.

[0065] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
