Description

Technical Field

[0001] The utility model relates to the technical field of flat grain robots, and particularly to an installation structure of a flat grain driving wheel of a flat grain robot. Background Art

[0002] A flat grain robot refers to a flattening device that walks in a granary to gradually flatten the piled-up grains so as to improve the capacity utilization rate of the granary or the grain storage container. Among them, there is a flat grain robot that adopts the structural scheme of a flat grain driving wheel. The flat grain driving wheel is both a walking component and a flat grain component. For example, a segmented variable pitch spiral driving flat storage robot disclosed in the Chinese invention patent application with the publication number CN113396705A. Since the volume of the granary is generally very large, a spiral staircase is generally provided to reach the personnel entrance at the top. Therefore, the staff needs to carry the flat grain robot to the top, enter through the personnel entrance, and then place the flat grain robot on the top of the grain pile. Then the flat grain robot starts to work and crawls on the top of the grain pile. The flat grain driving wheel not only drives the flat grain robot to move, but also pushes the grains during the movement, thereby gradually flattening the spire-shaped grain pile.

[0003] As can be seen from the above, the flat grain driving wheel is a core component, and the flat grain driving wheel acts on the grains. The applicant believes that the installation convenience and light weight of the flat grain driving wheel are of great significance to the flat grain robot. Therefore, how to design the installation structure of the flat grain driving wheel needs further research. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and propose an installation structure of a flat grain driving wheel of a flat grain robot, which has high installation convenience and is beneficial to light weight.

[0005] Compared with the prior art, the utility model proposes an installation structure of a flat grain driving wheel of a flat grain robot, which includes a flat grain driving wheel and an output shaft. The output shaft is provided with a guiding support rod coaxially arranged. The flat grain driving wheel is sleeved on the guiding support rod. One end of the output shaft is provided with a first part of a detachable axially concave-convex plug-in and matching structure. One end of the flat grain driving wheel on the side of the output shaft is provided with a second part of a detachable axially concave-convex plug-in and matching structure. When the flat grain driving wheel is sleeved on the guiding support rod, one end of the output shaft and one end of the flat grain driving wheel are in transmission connection through the axial concave-convex plug-in and matching between the first part and the second part. The guiding support rod is provided with an axial limiting member at the other end of the flat grain driving wheel. The axial limiting member is detachably connected to the guiding support rod. The axial limiting member axially limits the flat grain driving wheel between one end of the output shaft and the other end of the flat grain driving wheel. The output shaft rotates to drive the flat grain driving wheel to rotate.

[0006] After adopting the above structure, compared with the prior art, the utility model has the following advantages:

[0007] Through improvement, on the one hand, when installing the grain leveling drive wheel, first, the grain leveling drive wheel is sleeved with the guiding support rod, and then the axial limiting member is connected to complete the axial limit. Thus, the installation of the grain leveling drive wheel is completed, and at the same time, the transmission connection is completed, which is very convenient. When disassembly, maintenance or replacement is required, first disassemble the axial limiting member, and then remove the grain leveling drive wheel from the guiding support rod. On the other hand, since one end of the output shaft is in transmission connection with one end of the grain leveling drive wheel through the axial concave-convex insertion fit between the first part and the second part, the guiding support rod mainly plays an axial supporting role. Then, according to the mechanical principle, the guiding support rod does not need to adopt a solid part, and a hollow structure inside the guiding support rod can also be used in the present disclosure. Therefore, the wall thickness of the guiding support rod can be made thinner, so as to greatly reduce the weight. Even if the length of the grain leveling drive wheel is relatively long, it can still be relatively lightweight. That is to say, the design of the present disclosure provides a precondition for lightweight. Therefore, according to the design of the present disclosure, preferably, any rod with sufficient axial support and lightweight can be used in the present disclosure, such as a carbon fiber rod.

[0008] In summary, the present disclosure has high installation convenience and is beneficial to lightweight.

[0009] In some embodiments, the output shaft is provided with an axially through hole, and the guiding support rod is sleeved with the axially through hole. The guiding support rod passes through the output shaft, and both ends of the guiding support rod extend out to form a left support rod and a right support rod. A grain leveling drive wheel is sleeved on each of the left support rod and the right support rod, and two axial limiting members are correspondingly provided to axially limit the two grain leveling drive wheels. Both ends of the output shaft are provided with a first part.

[0010] In some embodiments, the other end of the grain leveling drive wheel is provided with a socket hole, and an axially socketed part is detachably sleeved in the socket hole. The axially socketed part is provided with a limiting end part, and the limiting end part abuts against the end part of the other end of the grain leveling drive wheel along the axial direction. The guiding support rod sequentially passes through the axially socketed part and the limiting end part to form a connection end, and the connection end connects the axial limiting member, and the axial limiting member axially presses the limiting end part against the end part of the other end of the grain leveling drive wheel.

[0011] In some embodiments, an insertion structure is provided in the circumferential direction between the socket hole and the axially socketed part. The insertion structure includes an axially slot and an axially inserted part, and the insertion structure is used to limit the rotation of the axially socketed part after the axially socketed part is sleeved with the socket hole.

[0012] In some embodiments, it further includes a cover, and the cover is connected to the limiting end part.

[0013] In some embodiments, the cover adopts a diversion cover.

[0014] In some embodiments, a protective socket portion is provided at one end of the grain-leveling drive wheel, the second portion is disposed in the protective socket portion, and the end face of the second portion is flush with or recessed from the end face of the protective socket portion. When the first portion and the second portion are axially engaged with each other in a concave-convex manner, the first portion is located in the protective socket portion.

[0015] In some embodiments, the protective socket portion has a guiding shape.

[0016] In some embodiments, the guiding support rod is an axially hollow tube. Description of the Drawings

Therefore, the above terms should not be understood as limiting the present invention.

[0029] like Figures 1 to 9 The figure shows a flat grain driving wheel installation structure of a flat grain robot, including a flat grain driving wheel 1 and an output shaft 2. The output shaft 2 is provided with a coaxially arranged guide support rod 3. The flat grain driving wheel 1 is sleeved with the guide support rod 3. One end of the output shaft 2 is provided with a first part 4 of a detachable axial concave-convex plug-in matching structure. The end of the flat grain driving wheel 1 located on the side of the output shaft 2 is provided with a second part 5 of a detachable axial concave-convex plug-in matching structure. When the flat grain driving wheel 1 is sleeved with the guide support rod 3, one end of the output shaft 2 and one end of the flat grain driving wheel 1 are transmission connected through the axial concave-convex plug-in matching between the first part 4 and the second part 5. The guide support rod 3 is provided with an axial limiter 6 at the other end of the flat grain driving wheel 1. The axial limiter 6 is detachably connected to the guide support rod 3. The axial limiter 6 axially limits the flat grain driving wheel 1 between one end of the output shaft 2 and the other end of the flat grain driving wheel 1. The rotation of the output shaft 2 is used to drive the flat grain driving wheel 1 to rotate.

[0030] In this example, if Figure 3 , 4 As shown in , 5, the output shaft 2 is installed in the transmission box 22, the transmission box 22 is installed with the electric motor 18, the transmission box 22 is provided with a transmission gear 17, the transmission gear 17 is sleeved on the output shaft 2, and the transmission gear 17 and the output shaft 2 are connected by a key 20 and a keyway 21. Since the key 20 and the keyway 21 are used for the transmission connection, it can be seen that the output shaft 2 is relatively thick, and the thick output shaft 2 is suitable for setting the keyway 21. Therefore, the transmission path is roughly the electric motor 18, the transmission gear 17, the output shaft 2 and then to the flat grain driving wheel 1.

[0031] In some embodiments, the guiding support rod 3 is arranged to be rotatably connected to the output shaft 2. When the output shaft 2 rotates to drive the grain leveling driving wheel 1 to rotate, the guiding support rod 3 may not rotate synchronously. In other embodiments, the guiding support rod 3 is arranged to rotate synchronously. In the embodiments, the case where the guiding support rod 3 is arranged to rotate synchronously is mainly exemplified.

[0032] In some embodiments, as Figure 3 , 4 , as shown in Figure 5, both ends of the output shaft 2 extend out of the outer side of the transmission box 22. The output shaft 2 is provided with an axially through hole 7. The guiding support rod 3 is sleeved and matched with the axially through hole 7. The guiding support rod 3 passes through the output shaft 2, and both ends of the guiding support rod 3 extend out 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 grain leveling driving wheel 1, and two axial limiting members 6 are correspondingly provided to axially limit the two grain leveling driving wheels 1. Both ends of the output shaft 2 are provided with a first part 4. In this way, on the one hand, two grain leveling driving wheels 1 can be installed, with higher working efficiency. On the other hand, with the cooperation of the left first part 4 and the second part 5, and with the cooperation of the right first part 4 and the second part 5, the guiding support rod 3 is limited and fixed by the two axial limiting members 6, and only the guiding support rod 3 needs to be sleeved and matched with the axially through hole 7, greatly simplifying the connection relationship between the guiding support rod 3 and the output shaft 2, thus simplifying the structure and reducing the volume.

[0033] In some embodiments, as Figure 4 , 7 , as shown in Figure 8, the other end of the grain leveling driving wheel 1 is provided with a socket hole 10. The socket hole 10 is detachably sleeved with an axially socketed part 11. The axially socketed part 11 is provided with a limiting end part 12. The limiting end part 12 abuts against the end part of the other end of the grain leveling driving wheel 1 along the axial direction. The guiding support rod 3 sequentially passes through the axially socketed part 11 and the limiting end part 12 to form a connection end 13. The connection end 13 is connected to the axial limiting member 6, and the axial limiting member 6 axially presses the limiting end part 12 against the end part of the other end of the grain leveling driving wheel 1. In this way, on the one hand, the axially socketed part 11 has a supporting effect on the other end of the grain leveling driving wheel 1, which is beneficial to maintaining the strength and shape of the grain leveling driving wheel 1. On the other hand, since the diameter of the grain leveling driving wheel 1 is relatively large, after adopting the foregoing technical solution, it is beneficial to make the diameter of the guiding support rod 3 smaller without having to make it larger, which is beneficial to weight reduction. On the third hand, the foregoing technical solution has a relatively simple structure and is convenient for disassembly and assembly.

[0034] The axial limiting member 6 is, for example, a nut, and the connection end 13 is, for example, a screw section.

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

[0036] Furthermore, as Figure 3 , 4 shown, the cover 16 is a fairing. This is beneficial for the leveling robot to walk smoothly on the grain pile and perform the leveling work.

[0037] In some embodiments, as Figure 4 , 7 , and as shown in 8, a plugging structure is provided circumferentially between the socket hole 10 and the axial socket part 11. The plugging structure includes an axial slot 14 and an axial insertion part 15. The plugging structure is used to limit the rotation of the axial socket part 11 after the axial socket part 11 and the socket hole 10 are socketed and matched. In this way, the problem that the axial socket part 11 and the limiting end 12 rotate relative to the leveling driving wheel 1 is solved, avoiding looseness and wear. At the same time, the problem of how the guiding support rod 3 rotates synchronously is also solved relatively simply, that is, the output shaft 2 drives the leveling driving wheel 1 to rotate, the leveling driving wheel 1 drives the axial socket part 11 and the limiting end 12 to rotate, and the two limiting ends 12 drive the guiding support rod 3 to rotate.

[0038] In some embodiments, as Figure 2 , 3 , 4, and 9 shown, one end of the leveling driving wheel 1 is provided with a protective socket part 17, the second part 5 is arranged in the protective socket part 17, and the end face of the second part 5 is flush with or indented from the end face of the protective socket part 17. When the first part 4 and the second part 5 are axially inserted and matched, the first part 4 is located in the protective socket part 17. In this way, after the first part 4 and the second part 5 are connected, they are hidden in the protective socket part 17 and protected by the protective socket part 17. This design has great benefits in an environment such as a grain pile, avoiding wear and abnormalities at the connection of the first part 4 and the second part 5.

[0039] In some embodiments, as Figure 2 , 3 , 4, and 9 shown, the protective socket part 17 has a guiding shape, and the purpose of the guiding shape is that the passing grains can pass smoothly, which is beneficial for the leveling robot to walk smoothly on the grain pile and perform the leveling work. The guiding shape is, for example, conical, arc-shaped, etc. Any applicable guiding shape can be used in the present disclosure.

[0040] In some embodiments, as Figure 4 shown, for light weight, the guiding support rod 3 is an axially hollow tube, such as a seamless steel tube, an aluminum alloy tube, etc.

[0041] In this example, both the first part 4 and the second part 5 adopt the structure of axial grooves and axial protrusions, and the detachable axial concave-convex plug-in fit structure is formed by the cooperation of the corresponding axial grooves and axial protrusions. Any applicable detachable axial concave-convex plug-in fit structure can be used in this disclosure.

[0042] When understanding this disclosure, if necessary, the above structure can refer to other embodiments / attachments Figure 1 and it is understood that no further elaboration will be provided here.

[0043] The above are only the illustrative embodiments of the present invention. Therefore, any equivalent changes or modifications made to the structure, features, and principles described within the scope of the patent protection of the present invention are included within the scope of the patent protection of the present invention.
