Description

Technical Field

[0001] This invention relates to the field of grain leveling robot technology, specifically to a grain leveling drive wheel mounting structure for a grain leveling robot. Background Technology

[0002] A grain leveling robot is a device that moves within a grain silo to gradually flatten piles of grain, thereby improving the utilization rate of the silo or grain storage container. One type of grain leveling robot employs a structure with a grain leveling drive wheel, which serves as both the walking component and the grain leveling component. For example, Chinese invention patent application CN113396705A discloses a segmented variable pitch spiral-driven grain leveling robot. Since grain silos are generally very large, they typically have a spiral staircase leading to a personnel entrance at the top. Therefore, workers need to lift the grain leveling robot to the top, enter through the personnel entrance, and place the robot on top of the grain pile. The grain leveling robot then begins its work, crawling along the top of the grain pile. The grain leveling drive wheel both moves the robot and pushes the grain during this movement, gradually leveling the pointed top of the grain pile.

[0003] As can be seen from the above, the grain leveling drive wheel is a core component. The grain leveling drive wheel acts on the grain. The applicant believes that the ease of installation and lightweight design of the grain leveling drive wheel are of great significance to the grain leveling robot. Therefore, how to design the installation structure of the grain leveling drive wheel needs further research. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and propose a grain leveling robot grain leveling drive wheel mounting structure, which has high installation convenience and is conducive to weight reduction.

[0005] Compared with the prior art, the present invention proposes a leveling drive wheel mounting structure for a leveling robot, including a leveling drive wheel and an output shaft. The output shaft is provided with a coaxially arranged guide support rod. The leveling drive wheel is sleeved with the guide support rod. One end of the output shaft is provided with a first part of a detachable axial concave-convex insertion and engagement structure. The end of the leveling drive wheel located on the same side as the output shaft is provided with a second part of the detachable axial concave-convex insertion and engagement structure. When the leveling drive wheel is sleeved with the guide support rod, one end of the output shaft and one end of the leveling drive wheel are connected by transmission through the axial concave-convex insertion and engagement between the first part and the second part. The guide support rod is provided with an axial limiting member at the other end of the leveling drive wheel. The axial limiting member is detachably connected to the guide support rod. The axial limiting member axially limits the leveling drive wheel between one end of the output shaft and the other end of the leveling drive wheel. The rotation of the output shaft is used to drive the leveling drive wheel to rotate.

[0006] Compared with the prior art, the present invention has the following advantages after adopting the above structure:

[0007] This disclosure improves upon existing methods in two ways. First, when installing the leveling drive wheel, the drive wheel is first connected to the guide support rod, and then the axial limiting component is connected to complete the axial limiting. This completes both the installation of the leveling drive wheel and the transmission connection, which is very convenient. When disassembly, maintenance, or replacement is required, the axial limiting component is removed first, and then the leveling drive wheel is removed from the guide support rod. Second, since one end of the output shaft is connected to one end of the leveling drive wheel through an axial concave-convex interlocking fit between the first and second parts, the guide support rod mainly plays an axial support role. Therefore, according to the principles of mechanics, the guide support rod does not need to be a solid part. A hollow structure can also be used in this disclosure, so the wall thickness of the guide support rod can be made thinner, thereby greatly reducing the weight. Even if the leveling drive wheel is long, it can still be relatively lightweight. In other words, the design of this disclosure provides a prerequisite for lightweighting. Therefore, according to the design of this disclosure, preferably, any rod that has sufficient axial support and is lightweight can be used in this disclosure, such as a carbon fiber rod.

[0008] In summary, this disclosure offers high ease of installation and is beneficial for weight reduction.

[0009] In some embodiments, the output shaft is provided with an axial through hole, the guide support rod is sleeved with the axial through hole, the guide support rod passes through the output shaft, and the two ends of the guide support rod extend outward to form a left support rod and a right support rod. Each of the left support rod and the right support rod is sleeved with a leveling drive wheel, and two axial limiting members are provided to axially limit the two leveling drive wheels. Both ends of the output shaft are provided with a first part.

[0010] In some embodiments, the other end of the leveling drive wheel is provided with a sleeve hole, and the sleeve hole is detachably fitted with an axial sleeve portion. The axial sleeve portion is provided with a limiting end, and the limiting end abuts against the end of the other end of the leveling drive wheel along the axial direction. The guide support rod passes through the axial sleeve portion and the limiting end in sequence to form a connecting end. The connecting end is connected to the axial limiting member, and the axial limiting member axially presses the limiting end against the end of the other end of the leveling drive wheel.

[0011] In some embodiments, a circumferential insertion structure is provided between the socket hole and the axial sleeve portion. The insertion structure includes an axial slot and an axial insertion portion. The insertion structure is used to restrict the rotation of the axial sleeve portion after the axial sleeve portion is engaged with the socket hole.

[0012] In some embodiments, a cover is also included, which is connected to the limiting end.

[0013] In some embodiments, the cover is a flow deflector.

[0014] In some embodiments, one end of the leveling drive wheel is provided with a protective sleeve portion, and a second portion is provided in the protective sleeve portion. The end face of the second portion is flush with or recessed relative to the end face of the protective sleeve portion. When the first portion and the second portion are axially interlocked, the first portion is located in the protective sleeve portion.

[0015] In some embodiments, the protective sleeve has a flow-guiding shape.

[0016] In some embodiments, the guide support rod is an axially hollow tube. Attached Figure Description

Detailed Implementation

[0027] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0028] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0029] like Figures 1 to 9 The diagram shows the mounting structure of a leveling drive wheel for a leveling robot, including a leveling drive wheel 1 and an output shaft 2. The output shaft 2 has a coaxially arranged guide support rod 3. The leveling drive wheel 1 is sleeved with the guide support rod 3. One end of the output shaft 2 has a first part 4 of a detachable axial concave-convex insertion and engagement structure. The end of the leveling drive wheel 1 located on the same side as the output shaft 2 has a second part 5 of a detachable axial concave-convex insertion and engagement structure. When the leveling drive wheel 1 is sleeved with the guide support rod 3, one end of the output shaft 2 and one end of the leveling drive wheel 1 are connected by a transmission through the axial concave-convex insertion and engagement between the first part 4 and the second part 5. The guide support rod 3 has an axial limiting member 6 at the other end of the leveling drive wheel 1. The axial limiting member 6 is detachably connected to the guide support rod 3. The axial limiting member 6 axially limits the leveling drive wheel 1 between one end of the output shaft 2 and the other end of the leveling drive wheel 1. The rotation of the output shaft 2 drives the leveling drive wheel 1 to rotate.

[0030] In this example, as Figure 3 , 4 As shown in Figure 5, the output shaft 2 is installed in the transmission housing 22, which houses the electric motor 18. The transmission housing 22 also contains a transmission gear 17, which is sleeved on the output shaft 2. The transmission gear 17 and the output shaft 2 are connected by a key 20 and a keyway 21. Because of the key 20 and keyway 21, the output shaft 2 is relatively thick, as a thick output shaft 2 is suitable for the keyway 21. Therefore, the transmission path is approximately: electric motor 18, transmission gear 17, output shaft 2, and then to the leveling drive wheel 1.

[0031] In some embodiments, the guide support rod 3 is rotatably connected to the output shaft 2, so that when the output shaft 2 rotates, driving the leveling drive wheel 1 to rotate, the guide support rod 3 may rotate asynchronously. In other embodiments, the guide support rod 3 is configured to rotate synchronously. The embodiments mainly illustrate the case where the guide support rod 3 rotates synchronously.

[0032] In some embodiments, such as Figure 3 , 4 As shown in Figure 5, both ends of the output shaft 2 extend outside the transmission box 22. The output shaft 2 is provided with an axial through hole 7. The guide support rod 3 is sleeved with the axial through hole 7. The guide support rod 3 passes through the output shaft 2, and both ends of the guide support rod 3 extend outward to form a left support rod 8 and a right support rod 9. Each of the left support rod 8 and the right support rod 9 is sleeved with a leveling drive wheel 1, and two axial limiting members 6 are provided to axially limit the two leveling drive wheels 1. Both ends of the output shaft 2 are provided with a first part 4. In this way, on the one hand, two leveling drive wheels 1 can be installed, which has higher working efficiency. On the other hand, with the cooperation of the first part 4 and the second part 5 on the left and the first part 4 and the second part 5 on the right, the guide support rod 3 is limited and fixed by the two axial limiting members 6. It is only necessary to sleeve the guide support rod 3 with the axial through hole 7, which greatly simplifies the connection relationship between the guide support rod 3 and the output shaft 2, thus simplifying the structure and reducing the volume.

[0033] In some embodiments, such as Figure 4 , 7 As shown in Figure 8, the other end of the leveling drive wheel 1 is provided with a sleeve hole 10, and the sleeve hole 10 is detachably fitted with an axial sleeve part 11. The axial sleeve part 11 is provided with a limiting end 12, which abuts against the end of the other end of the leveling drive wheel 1 along the axial direction. The guide support rod 3 passes through the axial sleeve part 11 and the limiting end 12 in sequence to form a connecting end 13. The connecting end 13 is connected to the axial limiting member 6, which axially presses the limiting end 12 against the end of the other end of the leveling drive wheel 1. In this way, on the one hand, the axial sleeve part 11 provides support for the other end of the leveling drive wheel 1, which helps to maintain the strength and shape of the leveling drive wheel 1. On the other hand, since the diameter of the leveling drive wheel 1 is relatively large, the aforementioned technical solution allows the diameter of the guide support rod 3 to be smaller, without needing to be large, which helps to reduce weight. Furthermore, the aforementioned technical solution has a relatively simple structure and is easy to assemble and disassemble.

[0034] Axial limiting component 6, for example, a nut; connecting end 13, for example, a screw section.

[0035] Furthermore, such as Figure 3 , 4As shown, it also includes a cover 16, which is connected to the limiting end 12. In this way, the axial limiting member 6 is protected inside, and the limiting end 12 is also protected.

[0036] Furthermore, such as Figure 3 , 4 As shown, the cover 16 uses a flow guide. This facilitates the smooth movement of the grain leveling robot on the grain pile and its leveling work.

[0037] In some embodiments, such as Figure 4 , 7 As shown in Figure 8, a circumferential insertion structure is provided between the socket 10 and the axial socket 11. This insertion structure includes an axial slot 14 and an axial insertion part 15. The insertion structure is used to restrict the rotation of the axial socket 11 after it is engaged with the socket 10. In this way, the problem of the axial socket 11 and the limiting end 12 rotating relative to the leveling drive wheel 1 is solved, avoiding loosening and wear. At the same time, the problem of how the guide support rod 3 rotates synchronously is also solved relatively simply. That is, the output shaft 2 drives the leveling drive wheel 1 to rotate, the leveling drive wheel 1 drives the axial socket 11 and the limiting end 12 to rotate, and the two limiting ends 12 drive the guide support rod 3 to rotate.

[0038] In some embodiments, such as Figure 2 , 3 As shown in Figures 4 and 9, one end of the grain driving wheel 1 is provided with a protective sleeve 17, and the second part 5 is provided in the protective sleeve 17. The end face of the second part 5 is flush with or recessed relative to the end face of the protective sleeve 17. When the first part 4 and the second part 5 are axially interlocked, the first part 4 is located in the protective sleeve 17. In this way, the first part 4 and the second part 5 are hidden in the protective sleeve 17 after being connected, and are protected by the protective sleeve 17. This design has great advantages in the environment of grain piles, avoiding wear and abnormalities at the connection of the first part 4 and the second part 5.

[0039] In some embodiments, such as Figure 2 , 3 As shown in Figures 4 and 9, the protective sleeve 17 adopts a guide shape. The purpose of the guide shape is to allow the grain to pass through smoothly, which is beneficial for the grain leveling robot to walk smoothly on the grain pile and level the grain. The guide shape is, for example, conical, arc, etc., and any suitable guide shape can be used in this disclosure.

[0040] In some embodiments, such as Figure 4 As shown, for the purpose of weight reduction, the guide support rod 3 is made of axial hollow tube, such as seamless steel tube, aluminum alloy tube, etc.

[0041] In this example, both Part 4 and Part 5 employ an axial groove and an axial protrusion structure. The detachable axial concave-convex plug-in mating structure is formed by the corresponding axial groove and axial protrusion. Any applicable detachable axial concave-convex plug-in mating structure can be used in this disclosure.

[0042] When understanding this disclosure, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that's understood, so I won't go into details here.

[0043] The above description is merely an illustrative embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of the present invention are included within the scope of protection of the present invention.
