Description

Technical Field

[0001] The utility model relates to the technical field of flat grain robots, and specifically relates to a driving structure 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 a grain storage container. Among them, there is a flat grain robot that adopts a structural scheme of flat grain driving wheels. The flat grain driving wheels are both walking components and flat grain components. For example, a segmented variable pitch spiral driving flat storage robot disclosed in a Chinese invention patent application with the publication number CN113396705A. The flat storage robot includes two rotating cylinders arranged in parallel. The rotating cylinder sequentially includes, from one end to the other end: a first section, a second section, and a third section; a plurality of first blades, which are arranged on the first section and are arranged in a spiral shape along the axial direction; a plurality of second blades, which are arranged on the third section and are arranged in a spiral shape along the axial direction; wherein, the pitch between adjacent first blades is different from the pitch between adjacent second blades; the rotation directions of all the blades on the same rotating cylinder are the same, and the rotation directions of the blades on the two rotating cylinders are opposite; two driving mechanisms, which are arranged on the frame and respectively drive the rotating cylinders to rotate in a matching manner.

[0003] As can be seen from the above, the rotating cylinder is the flat grain driving wheel. Currently, the driving structure uses the form of an electric motor connected to a reducer to drive the flat grain driving wheel. However, the existing driving structure is relatively high in height and high in structural cost. 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 a driving structure of a flat grain robot, which is beneficial to reducing the height and also beneficial to reducing the cost.

[0005] Compared with the prior art, the utility model proposes a driving structure of a flat grain robot, which includes an electric motor and a reducer. The reducer is provided with an output shaft, and the output shaft is connected to the flat grain driving wheel of the flat grain robot. One side of the reducer in the horizontal direction is provided with an opening. The end cover of the electric motor on the side of its output shaft is connected to one side of the reducer in the horizontal direction and covers the opening. The output shaft is integrally provided with a driving gear and is coaxially arranged. A driven gear is arranged in the reducer. The driven gear is arranged on the output shaft and is coaxially arranged. The axis of the driving gear and the axis of the driven gear are arranged in a perpendicular intersecting distribution. When the end cover covers the opening, the output shaft carries the driving gear and inserts into the reducer through the opening and meshes with the driven gear.

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

[0007] Through improvement, an opening is provided on one lateral side of the speed reducer. The end cover of the motor on the side of its output shaft is connected to the lateral side of the speed reducer and covers the opening. In this way, the end cover of the motor serves as both the covering component for the opening and the connecting component for connecting the motor to the speed reducer. Therefore, after the motor is connected to the speed reducer, it is beneficial to reduce the height in the lateral direction. At the same time, since the end cover is used as both the covering component and the connecting component, the number of components is greatly reduced, which is conducive to cost reduction.

[0008] In some embodiments, the housing of the speed reducer is an integral component, and an axial through-hole is provided along the axial direction of the output shaft, and the aforementioned opening is provided in the lateral direction.

[0009] In some embodiments, the end cover is provided with a socket part extending towards the opening side, and the socket part is socket-fitted with the opening to position the motor.

[0010] In some embodiments, the socket part is provided with a first bearing, and the first bearing is connected to the output shaft. The first bearing is used to position and rotatably support the output shaft.

[0011] In some embodiments, two or more first bearings are sequentially arranged along the axial direction of the output shaft.

[0012] In some embodiments, the end cover extends along the axial direction and in the direction opposite to the output shaft side to form an axial support part. The axial support part extends to the tail of the motor, and a second bearing is provided at the part of the axial support part located at the tail of the motor. The rotating shaft of the motor is rotatably socket-fitted with the end cover, and the rotating shaft is positioned and rotatably supported by the first bearing and the second bearing.

[0022] As Figures 1 to 6 Shown is a driving structure of a leveling robot, including a motor 1 and a speed reducer 2. The speed reducer 2 is provided with an output shaft 3, and the output shaft 3 is connected to the leveling drive wheel 4 of the leveling robot. One side of the speed reducer 2 in the transverse direction is provided with an opening 5. The end cover 7 on the side of the output shaft 6 of the motor 1 is connected to one side of the speed reducer 2 in the transverse direction and covers the opening 5. The output shaft 6 is integrally provided with a driving gear 8 and is coaxially arranged. A driven gear 9 is provided in the speed reducer 2. The driven gear 9 is arranged on the output shaft 3 and is coaxially arranged. The axis of the driving gear 8 and the axis of the driven gear 9 are arranged in a right-angled intersection. When the end cover 7 covers the opening 5, the output shaft 6 carries the driving gear 8 and is inserted into the speed reducer 2 through the opening 5 and meshes with the driven gear 9.

[0023] The assembly method can refer to Figure 2As shown in the figure, first, the output shaft 3 and the driven gear 9 are installed in the housing of the speed reducer 2 to form an assembly. Of course, the output shaft 3 can be further connected to the leveling drive wheel 4 to form a drive assembly with the speed reducer 2. Then, the pre-assembled motor 1 is connected to the drive assembly up and down at the opening 5 and fixed with bolts 17 to complete the assembly. When the motor 1 is connected to the drive assembly up and down, the output shaft 3 can be appropriately rotated to drive the driven gear 9, so that the driven gear 9 and the driving gear 8 are in good meshing, enabling the motor 1 to be installed in place relative to the opening 5. After being installed in place, it can be fixed with bolts 17.

[0024] In some embodiments, as Figure 5 shown, the housing of the speed reducer 2 is an integral part, and an axial through hole 10 is provided along the axial direction of the output shaft 3, and the opening 5 is provided transversely. The integral part is, for example, an integrally die-cast part, an integrally injection-molded part, an integrally cast part, and so on.

[0025] In some embodiments, as Figure 2 、 4 、6 shown, the end cover 7 is provided with a socket part 11 extending towards the opening 5, and the socket part 11 is socket-fitted with the opening 5 to position the motor 1. This is crucial for the present disclosure because the leveling robot has a large force during operation. How to ensure the support strength is one of the difficulties. By using the socket part 11 to be socket-fitted with the opening 5 to position the motor 1, on the one hand, it is beneficial to improve the support strength, and on the other hand, it is beneficial to ensure the position stability of the motor 1 relative to the opening 5, and further beneficial to maintain the stability of the output shaft 6 relative to the driven gear 9, thus beneficial to maintaining the good meshing between the driven gear 9 and the driving gear 8. Therefore, it has high reliability during the long-term operation of the leveling robot.

[0026] In some embodiments, as Figure 4 shown, the socket part 11 is provided with a first bearing 12, and the first bearing 12 is connected to the output shaft 6. The first bearing 12 is used to position and rotationally support the output shaft 6.

[0027] Furthermore, as Figure 4 shown, two or more first bearings 12 are provided in sequence along the axial direction of the output shaft 6. In this way, it has better support strength, further ensuring the structural stability of the output shaft 6 relative to the driven gear 9, thus being beneficial to further maintaining the good meshing between the driven gear 9 and the driving gear 8.

[0028] In some embodiments, as Figure 4 、 6As shown, an axial support portion 13 is provided on the end cover 7 extending axially and in a direction opposite to the side of the output shaft 6. The axial support portion 13 extends to the tail of the motor 1, and a second bearing 14 is provided at the portion of the axial support portion 13 located at the tail of the motor 1. The rotating shaft 17 of the motor 1 is rotatably sleeved with the end cover 7, and the rotating shaft 17 is positioned and rotatably supported by the first bearing 12 and the second bearing 14. In this way, the position stability of the rotating shaft 17 relative to the opening 5 is greatly guaranteed, so that in the mass manufacturing process, it is beneficial to maintain the stability of the output shaft 6 relative to the driven gear 9, and the driven gear 9 and the driving gear 8 are in good meshing.

[0029] In this example, as Figure 4 shown, in order to hold the second bearing 14, a limiting portion 15 is further provided at the tail of the motor 1 to axially limit the second bearing 14 through the limiting portion 15.

[0030] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices Figure 1 and be understood, and will not be elaborated here.

[0031] The above are only the exemplary embodiments of the present invention for illustration purposes. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the protection scope of the present invention patent are included in the protection scope of the present invention patent.
