Description

Technical Field

[0001] The utility model relates to the technical field of grain-leveling robots, and specifically relates to a grain-leveling driving wheel of a grain-leveling robot. Background Art

[0002] A grain-leveling robot refers to a leveling device that walks in a granary to gradually push flat the piled-up grains to improve the capacity utilization rate of the granary or the grain storage container. Among them, there is a structural scheme of a grain-leveling robot using a grain-leveling driving wheel. This grain-leveling driving wheel is both a walking component and a grain-leveling component. For example, a segmented variable pitch spiral driving and leveling 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 set up to reach the personnel entrance at the top. Therefore, the staff needs to carry the grain-leveling robot to the top, enter through the personnel entrance, and then place the grain-leveling robot on the top of the grain pile. Then the grain-leveling robot starts to work and crawls on the top of the grain pile. The grain-leveling driving wheel not only drives the grain-leveling robot to move, but also pushes the grains during the movement, thereby gradually flattening the pointed grain pile.

[0003] As can be seen from the above, reducing the weight of the grain-leveling robot is beneficial for the staff to carry. Therefore, how to reduce the weight is worthy of key 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 a grain-leveling driving wheel of a grain-leveling robot, which is beneficial for weight reduction.

[0005] Compared with the prior art, the utility model proposes a grain-leveling driving wheel of a grain-leveling robot, which includes a rotating cylinder and a grain-leveling part arranged on the outer periphery of the rotating cylinder. The rotating cylinder is provided with an axial weight-reducing through hole axially penetrating through the rotating cylinder, and a connecting part is arranged 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 sequentially includes a transmission part and an intermediate plastic part from the inside to the outside. The intermediate plastic part is injection-molded and coated on the transmission part to form a first composite component. The rotating cylinder is injection-molded and coated on the intermediate plastic part of the first composite component to form the grain-leveling driving wheel. The transmission part is used to connect with the output shaft of the grain-leveling robot. When the transmission part rotates, the rotating cylinder is driven to rotate through the intermediate plastic part.

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

[0007] Through improvement, the present disclosure provides that the rotating cylinder is provided with an axially penetrating weight-reducing through-hole along the axial direction of the rotating cylinder, and a connecting portion is provided. The connecting portion sequentially includes a transmission member and an intermediate plastic member from the inside to the outside. The intermediate plastic member is injection-molded and coated on the transmission member to form a first composite component. The rotating cylinder is injection-molded and coated on the intermediate plastic member of the first composite component to form a leveling driving wheel. The transmission member is used to connect to the output shaft of the leveling robot. When the transmission member rotates, the rotating cylinder is driven to rotate through the intermediate plastic member, thereby achieving the purpose of weight reduction while ensuring the transmission requirements.

[0008] Meanwhile, in the present disclosure, the main body is a plastic part, which is relatively light. In order to ensure transmission, the transmission member can be a metal part, a high-strength plastic part, a glass fiber reinforced part, a carbon fiber part or other high-strength transmission parts. Considering from the economic and technological perspectives, a metal part is generally used. Since the metal part is only a small section, the weight is relatively light. And because the diameter of the rotating cylinder is relatively large, through the transition of the intermediate plastic part and the setting of the axially weight-reducing through-hole, the rotating cylinder can be made thinner to make the weight lighter.

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

[0010] In some embodiments, an end cover is provided at the other end of the rotating cylinder, and the end cover is connected to the axially weight-reducing through-hole to close the axially weight-reducing through-hole.

[0011] In some embodiments, the end cover is provided with an axially sleeved portion, and the axially sleeved portion is sleeved with the axially weight-reducing through-hole.

[0012] In some embodiments, the end cover is detachably connected with a diversion cover.

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

[0014] In some embodiments, a plurality of grooves axially arranged are provided on the outer peripheral wall of the intermediate plastic member, and a second protrusion is formed between adjacent grooves. When the rotating cylinder is injection-molded and coated on the intermediate plastic member, 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 in a trapezoidal shape with a narrow opening and a wide bottom.

[0016] In some embodiments, when the rotating cylinder is injection-molded and coated on the intermediate plastic member 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 fits with the inner end. Description of the Drawings

Therefore, the above terms should not be construed as limitations on the present utility model

[0029] AsFigures 1 to 9 Shown is a leveling drive wheel of a leveling robot, which includes a rotating cylinder 1 and a leveling part 2 provided on the outer periphery of the rotating cylinder 1. The rotating cylinder 1 is provided with an axial weight reduction through hole 3 axially penetrating through the rotating cylinder 1, and a connecting part 4 is provided in the axial weight reduction through hole 3. The axial length of the connecting part 4 is less than the length of the axial weight reduction through hole 3. The connecting part 4 sequentially includes a transmission part 5 and an intermediate plastic part 6 from the inside to the outside. The intermediate plastic part 6 is injection-molded and coated on the transmission part 5 to form a first composite component. The rotating cylinder 1 is injection-molded and coated on the intermediate plastic part 6 of the first composite component to form a leveling drive wheel. The transmission part 5 is used to connect with the output shaft of the leveling robot. When the transmission part 5 rotates, the rotating cylinder 1 is driven to rotate through the intermediate plastic part 6.

[0030] In this example, the transmission part 5 is, for example, a metal part or a nylon part. Through the injection molding process, the transmission part 5 is coated with the intermediate plastic part 6 to form a first composite component. This first composite component serves as the connecting part 4, and the connecting part 4 is injection-molded and coated with a layer of plastic to form the rotating cylinder 1. The rotating cylinder 1 together with the connecting part 4 forms a leveling drive wheel. Therefore, the leveling drive wheel can be made with a larger diameter and lighter weight. Then, for a leveling robot equipped with multiple leveling drive wheels, the overall weight of the machine 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, as Figure 3 shown, the connecting part 4 is provided at one end of the rotating cylinder 1 close to the output shaft, so that the connection between the output shaft and the connecting part 4 can be more convenient and closer. The connection between the output shaft and the connecting part 4 can be screw connection, socket connection, welding, etc.

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

[0033] In some embodiments, as Figure 3 shown, the end cover 7 is provided with an axial socket part 8, and the axial socket part 8 is socketed with the axial weight reduction through hole 3. In this way, the axial socket part 8 can play a certain supporting role for the axial weight reduction through hole 3. Thus, the axial socket part 8 and the connecting part 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, as Figure 1 、 3 shown, the end cover 7 is detachably connected with a diversion cover 9. In this way, when the rotating cylinder 1 rotates, the end part on the side of the end cover 7 has less resistance.

[0035] In some embodiments, asFigure 4 , 5 As shown in 5 , a plurality of first protrusions 10 arranged axially are provided in the circumferential direction of the transmission member 5, and the first protrusions 10 are embedded in the intermediate plastic member 6 when the intermediate plastic member 6 is injection-molded and coated on the transmission member 5. In this way, the combination between the transmission member 5 and the intermediate plastic member 6 is more firm, and at the same time, the first protrusions 10 are beneficial to transmission.

[0036] In some embodiments, as Figure 5 , 6 , as shown in 7, a plurality of grooves 11 arranged axially are provided on the outer peripheral wall of the intermediate plastic member 6, and a second protrusion 12 is formed between adjacent grooves 11. When the rotating cylinder 1 is injection-molded and coated on the intermediate plastic member 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 combination between the intermediate plastic member 6 and the rotating cylinder 1 is more firm, and at the same time, the second protrusion 12 is beneficial to transmission.

[0037] Furthermore, for a more firm connection, as Figure 7 shown in Figure 7 , the groove 11 is in a trapezoidal shape with a narrow opening and a wide bottom, so that the inner peripheral wall of the rotating cylinder 1 embedded in each groove 11 is not easily separated from the groove 11, and at the same time, it has good transmission strength.

[0038] In some embodiments, as Figure 3 shown in Figure 3 , when the rotating cylinder 1 is injection-molded and coated on the intermediate plastic member 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 portion 4, and the baffle 13 is in mutual fit with the inner end. In this way, when the rotating cylinder 1 is injection-molded and coated on the intermediate plastic member 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 is bound to flow to the position where the baffle 13 is located to form the baffle 13, which can greatly facilitate the filling of the material of the inner peripheral wall of the rotating cylinder 1 into the groove 11.

[0039] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / attachments Figure 1 and be understood, and will not be elaborated here.

[0040] The above are only the exemplary embodiments for illustration of the present invention. 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.
