Description

Technical Field

[0001] This invention relates to the field of grain leveling robot technology, specifically to a grain leveling drive wheel 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, reducing the weight of the Pingliang robot makes it easier for workers to handle, so how to reduce its weight is a key area of ​​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 leveling drive wheel for a leveling robot, which is beneficial to weight reduction.

[0005] Compared with the prior art, the present invention proposes a leveling drive wheel for a leveling robot, including a rotating cylinder and a leveling part disposed on the outer periphery of the rotating cylinder. The rotating cylinder has an axial weight-reducing through hole that extends through the axial direction of the rotating cylinder, and a connecting part is provided in the axial weight-reducing through hole. The axial length of the connecting part is less than the length of the axial weight-reducing through hole. The connecting part includes, from the inside to the outside, a transmission component and an intermediate plastic component. The intermediate plastic component is injection molded onto the transmission component to form a first composite component. The rotating cylinder is injection molded onto the intermediate plastic component of the first composite component to form a leveling drive wheel. The transmission component is used to connect with the output shaft of the leveling robot. When the transmission component rotates, the rotating cylinder is driven to rotate through the intermediate plastic component.

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

[0007] This disclosure improves upon the previous method by providing an axial weight-reduction through-hole that runs through the axial direction of the rotating cylinder, and also includes a connecting portion. This connecting portion, from the inside out, sequentially includes a transmission component and an intermediate plastic component. The intermediate plastic component is injection molded onto the transmission component to form a first composite assembly. The rotating cylinder is injection molded onto the intermediate plastic component of the first composite assembly to form a grain leveling drive wheel. The transmission component is used to connect to the output shaft of the grain leveling robot. When the transmission component rotates, the intermediate plastic component drives the rotating cylinder to rotate, thereby achieving the purpose of weight reduction while ensuring the transmission requirements.

[0008] Meanwhile, the main body of this disclosure is made of plastic parts, which are relatively light. However, the transmission parts, in order to ensure transmission, can be made of metal parts, high-strength plastic parts, glass fiber reinforced parts, or carbon fiber parts, etc. From an economic and technological point of view, metal parts are generally used. Since the metal parts are only a small section, they are relatively light. Since the diameter of the rotating cylinder is relatively large, the intermediate plastic parts are used for transition and the axial weight reduction through holes are set, so that the rotating cylinder can be made thinner and lighter.

[0009] In some embodiments, the connecting portion is located at one end of the rotating cylinder near the output shaft.

[0010] In some embodiments, the other end of the rotating cylinder is provided with an end cap, which is connected to the axial weight reduction through hole to close the axial weight reduction through hole.

[0011] In some embodiments, the end cap is provided with an axial sleeve portion, which is sleeved with an axial weight reduction through hole.

[0012] In some embodiments, the end cap is detachably connected to a flow guide cap.

[0013] In some embodiments, the transmission member is provided with a plurality of axially arranged first protrusions in the circumferential direction, and the first protrusions are embedded in the intermediate plastic part when the intermediate plastic part is injection molded over the transmission member.

[0014] In some embodiments, the outer peripheral wall of the intermediate plastic part is provided with a plurality of axially arranged grooves, and a second protrusion is formed between adjacent grooves. When the rotating cylinder is injection molded onto the intermediate plastic part, the second protrusion is embedded in the rotating cylinder, and the inner peripheral wall of the rotating cylinder is embedded in each groove.

[0015] In some embodiments, the groove is a trapezoidal shape with a narrow opening and a wide bottom.

[0016] In some embodiments, when the rotating cylinder is injection molded onto the intermediate plastic part of the first composite component, a baffle is formed by injection molding. The baffle is located at the inner end of the connecting portion, and the baffle is in contact with the inner end. 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 9The image shows a leveling drive wheel for a leveling robot, comprising a rotating cylinder 1 and a leveling section 2 disposed on the outer periphery of the rotating cylinder 1. The rotating cylinder 1 has an axial weight-reducing through hole 3 extending through the axial direction of the rotating cylinder 1, and a connecting section 4 is provided inside the axial weight-reducing through hole 3. The axial length of the connecting section 4 is less than the length of the axial weight-reducing through hole 3. The connecting section 4 includes, from the inside out, a transmission component 5 and an intermediate plastic component 6. The intermediate plastic component 6 is injection molded onto the transmission component 5 to form a first composite component. The rotating cylinder 1 is injection molded onto the intermediate plastic component 6 of the first composite component to form a leveling drive wheel. The transmission component 5 is used to connect to the output shaft of the leveling robot. When the transmission component 5 rotates, the rotating cylinder 1 is driven to rotate through the intermediate plastic component 6.

[0030] In this example, the transmission component 5, such as a metal or nylon component, is formed by encasing the transmission component 5 in an intermediate plastic component 6 through injection molding. This first composite component serves as the connecting part 4, and the connecting part 4 is encased in a layer of plastic through injection molding to form a rotating cylinder 1. The rotating cylinder 1 together with the connecting part 4 forms the leveling drive wheel. Therefore, the leveling drive wheel can be made with a larger diameter and lighter weight. For a leveling robot with multiple leveling drive wheels, the overall weight will be reduced significantly, which is beneficial for handling and improving the battery life when the battery is used as the power source.

[0031] In some embodiments, such as Figure 3 As shown, the connecting part 4 is located at the end of the rotating cylinder 1 near the output shaft, which allows for a more convenient and closer connection between the output shaft and the connecting part 4. The connection between the output shaft and the connecting part 4 can be achieved through screwing, sleeve connection, welding, etc.

[0032] In some embodiments, such as Figure 3 As shown, the other end of the rotating cylinder 1 is provided with an end cap 7, which is connected to the axial weight reduction through hole 3 to close the axial weight reduction through hole 3. This prevents grain from entering.

[0033] In some embodiments, such as Figure 3 As shown, the end cap 7 is provided with an axial sleeve portion 8, which is sleeved with the axial weight reduction through hole 3. In this way, the axial sleeve portion 8 can provide a certain support for the axial weight reduction through hole 3, so that the axial sleeve portion 8 and the connecting portion 4 form a good support at both ends of the rotating cylinder 1, and the rotating cylinder 1 has good structural stability even when the wall thickness is relatively thin.

[0034] In some embodiments, such as Figure 1 , 3 As shown, the end cap 7 is detachably connected to the flow guide cover 9. In this way, when the rotating cylinder 1 rotates, the end of the end cap 7 has less resistance.

[0035] In some embodiments, such as Figure 4, 5 As shown, the transmission component 5 has a plurality of axially arranged first protrusions 10 circumferentially. The first protrusions 10 are embedded in the intermediate plastic component 6 when the intermediate plastic component 6 is injection molded and covered onto the transmission component 5. In this way, the transmission component 5 and the intermediate plastic component 6 are more firmly connected, and the first protrusions 10 facilitate transmission.

[0036] In some embodiments, such as Figure 5 , 6 As shown in Figures 7 and 8, the outer peripheral wall of the intermediate plastic part 6 is provided with multiple axially arranged grooves 11, and a second protrusion 12 is formed between adjacent grooves 11. When the rotating cylinder 1 is injection molded onto the intermediate plastic part 6, the second protrusion 12 is embedded in the rotating cylinder 1, and the inner peripheral wall of the rotating cylinder 1 is embedded in each groove 11. In this way, the intermediate plastic part 6 and the rotating cylinder 1 are more firmly connected, and the second protrusion 12 is beneficial for transmission.

[0037] Furthermore, for a more robust connection, such as Figure 7 As shown, the groove 11 is a trapezoidal shape with a narrow opening and a wide bottom, which makes it difficult for the inner circumferential wall of the rotating cylinder 1 embedded in each groove 11 to detach from the groove 11, while also having good transmission strength.

[0038] In some embodiments, such as Figure 3 As shown, when the rotating cylinder 1 is injection molded onto the intermediate plastic part 6 of the first composite component, a baffle 13 is formed by injection molding. The baffle 13 is located at the inner end of the connecting part 4, and the baffle 13 is in contact with the inner end. Thus, when the rotating cylinder 1 is injection molded onto the intermediate plastic part 6 of the first composite component, since the baffle 13 needs to be formed, the material of the inner peripheral wall of the rotating cylinder 1 must flow into the position where the baffle 13 is located to form the baffle 13, which greatly facilitates the filling of the groove 11 with the material of the inner peripheral wall of the rotating cylinder 1.

[0039] 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.

[0040] 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.
