Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a belt connection structure and a tomato harvester having the same. Background Technology

[0002] In various fields of machinery and equipment, belts are a crucial component, widely used in agricultural machinery and industrial equipment, playing an irreplaceable role in the stable operation of many machines. Taking tomato harvesters as an example, their belts are primarily used to transport crops. During actual operation, belts not only bear significant loads but also undergo frequent bending operations, constantly operating under high-intensity conditions.

[0003] With the acceleration of agricultural modernization, the requirements for the performance of agricultural machinery are constantly increasing. Under these circumstances, the reliability and stability of belt connection components have become key factors affecting the service life and working efficiency of equipment.

[0004] Currently, existing belt connection technologies generally use riveting or threaded fastening to secure the belt to other components. However, because the belt material is relatively soft, the rivet end often lacks sufficient support when using riveting. This makes the riveted connection structure prone to deformation during actual use, causing the steel rod to loosen and, in severe cases, even detach, which has a very adverse effect on the normal operation of the entire equipment. Utility Model Content

[0005] In view of this, the present invention provides a belt connection structure and a tomato harvester having the same, to solve the problem that one end of the steel rod easily detaches from the belt when used in the prior art.

[0006] This utility model provides a belt connection structure, including: a belt and a connector for connecting the belt, the belt and the connector being connected by a fastener, the fastener including an external threaded component and an internal threaded component, both the external threaded component and the internal threaded component having a cap structure and a rod structure; the side of the belt away from the connector has a groove, the groove having a through hole for the fastener to pass through, the rod structures of the external threaded component and the internal threaded component being inserted into the through hole and threadedly connected within the through hole; the cap structure of the external threaded component or the internal threaded component is accommodated within the groove of the belt, the depth of the groove being greater than or equal to the height of the cap structure of the external threaded component or the internal threaded component.

[0007] With the above configuration, the external and internal threaded parts are connected by threads within the through hole. Compared to traditional riveting methods, threaded connections offer better tightness and stability, providing continuous and uniform clamping force, and significantly reducing the risk of loosening due to uneven force. A groove is provided on the side of the belt away from the connector to accommodate the cap structure of either the external or internal threaded part, with the groove depth matching the height of the cap structure. On one hand, this design makes the entire connection structure more compact, avoiding situations like traditional nut not being countersunk and protruding from the belt surface, thus preventing wear on other components (such as gears and pulleys), ensuring smooth and stable equipment operation. On the other hand, the groove provides a stable support environment for the cap structure, solving the problem of insufficient support at one end of the rivet in traditional riveting. Even when the belt is subjected to heavy loads and frequent bending operations, the cap structure housed in the groove can maintain a tight state thanks to the support of the groove, preventing deformation of the connection structure due to stress. This prevents the steel rod from loosening and detaching, effectively solving the problem of the steel rod easily detaching from the belt. This greatly improves the reliability and stability of the belt connection components, ensuring the efficient and stable operation of equipment such as tomato harvesters.

[0008] Optionally, the groove is a rectangular groove, and the groove has at least one through hole.

[0009] With the above configuration, the rectangular groove has a regular shape, ensuring high precision and consistency, thereby reducing production difficulty and cost. Simultaneously, the inclusion of at least one through hole provides flexibility for fastener installation. Depending on the belt's application, load, and connector specifications, the number and layout of the through holes can be flexibly adjusted, better adapting to diverse application scenarios and fully leveraging the performance advantages of the belt connection structure.

[0010] Optionally, the internal threaded component includes a base plate, which is embedded in the groove. The base plate has at least one protrusion inserted into the through hole of the belt. The protrusion has an internal threaded hole for connection with the external threaded component.

[0011] With the above configuration, the substrate is embedded in the groove, making the connection between the internal threaded component and the belt more stable and precise. The substrate can closely fit the shape of the groove, providing a large area of ​​contact support, effectively dispersing the stress generated when the external threaded component is tightened, reducing the possibility of excessive local stress, and thus improving the stability of the entire connection structure. The design of at least one protrusion inserted into the belt through hole not only provides a positioning reference for the connection of the external threaded component, ensuring that the external threaded component can accurately connect with the internal threaded hole and avoid problems such as misalignment and offset during installation, but also enhances the mechanical bonding force between the internal threaded component and the belt.

[0012] Optionally, the groove has at least two through holes.

[0013] The above design significantly enhances the stability of the connection between the belt and the connector. The design with at least two through holes allows for multi-point connection of the fasteners, evenly distributing external force across multiple connection points. Multiple through holes, combined with the fasteners, prevent excessive stress in any one area, thereby greatly reducing the risk of loosening or deformation of the connection structure and significantly improving the reliability and stability of the entire equipment operation.

[0014] Optionally, the internal threaded component includes a base plate, which is embedded in the groove. The base plate has at least two protrusions, which are inserted into the through hole of the belt. Each protrusion has an internal threaded hole for connection with the external threaded component.

[0015] With the above-described configuration, the substrate is embedded in the groove, achieving precise positioning. During installation, operators can quickly place the internally threaded component in the correct position, reducing installation time and errors. At least two protrusions are inserted one-to-one with the belt through-holes, further clarifying the installation direction and making the alignment and connection of the externally threaded component with the protrusion's internal thread hole easier, improving assembly efficiency. The cooperation of multiple protrusions with the externally threaded component significantly enhances the connection strength. When the belt is subjected to tension, shear, or torque from various directions, each protrusion can share a portion of the external force, extending the service life of the entire connection structure.

[0016] Optionally, the root of the protruding post has a tapered section.

[0017] Through the above design, the tapered section enhances the tightness and stability of the connection between the protrusion and the belt. When the protrusion is inserted into the through hole of the belt, the tapered section acts as a guide, making the insertion process smoother. Simultaneously, because the diameter of the tapered section is larger than the diameter of the opening on the belt surface, it forms an interference fit with the belt hole after installation. This interference fit increases the friction and mechanical engagement force between the protrusion and the belt, effectively preventing the protrusion from loosening or shifting during use.

[0018] Optionally, the average diameter of the tapered segment is greater than the inner diameter of the through hole of the belt.

[0019] With the above configuration, the tapered section, due to its average diameter being larger than the inner diameter of the belt through-hole, will form an interference fit with the belt through-hole. This interference fit requires the application of a certain external force to overcome resistance when the protrusion is inserted into the belt through-hole, and this process makes the connection between the protrusion and the belt tighter.

[0020] Optionally, the height of the protrusion is less than the depth of the through hole in the belt.

[0021] With the above design, when the protrusion is inserted into the through hole of the belt, its top will not protrude excessively from the belt surface, thus avoiding unnecessary interference or friction between the protrusion and other components during belt operation. This helps reduce wear on the protrusion and extend its service life. At the same time, it also reduces the unevenness of the belt surface that may be caused by the protrusion, making the belt run more smoothly and steadily, and reducing vibration and noise caused by belt instability.

[0022] Optionally, the grooves have a plurality of grooves spaced apart along the length of the belt.

[0023] With the above settings, the connection points can be flexibly selected according to different working conditions, the external force on the belt can be distributed more evenly, the local stress concentration can be reduced, the service life of the belt can be extended, and the installation and replacement of the connecting parts can be facilitated, which greatly improves the applicability and reliability of the belt connection structure.

[0024] This utility model also provides a tomato harvester, including the aforementioned belt connection structure.

[0025] Through the above-mentioned design, the stability and reliability of the belt connection of the tomato harvester are greatly improved during use. When the tomato harvester is transporting crops, even if the belt is subjected to a large load and frequent bending, the new belt connection structure, with its rationally designed grooves, fasteners, and other components, can effectively prevent the connection from loosening or the steel rod from detaching. This ensures the continuous and efficient operation of the tomato harvester, reduces equipment failure and repair time, lowers maintenance costs, improves overall operating efficiency, and brings significant benefits to agricultural production.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] The following is combined with Figures 1 to 6 This describes embodiments of the present invention. Figure 1 The belt connection structure provided in this embodiment is applied to the conveyor belt 1 of a tomato harvester, wherein the belt 1 is fixed to the connecting rod through the belt connection structure.

[0037] like Figure 2 The diagram shows a specific implementation of the belt connection structure provided in this embodiment, which includes: belt 1, connector 2, and fasteners.

[0038] Specifically, the belt 1 and the connector 2 are connected by fasteners, which include an external threaded part 3 and an internal threaded part 4. Both the external threaded part 3 and the internal threaded part 4 have a cap structure and a rod structure. The side of the belt 1 away from the connector 2 has a groove 6. The groove 6 has a through hole 5 for the fastener to pass through. The rod structures of the external threaded part 3 and the internal threaded part 4 are inserted into the through hole 5 and threadedly connected within the through hole 5. The cap structure of the external threaded part 3 or the internal threaded part 4 is accommodated in the groove 6 of the belt 1. The depth of the groove 6 is greater than or equal to the height of the cap structure of the external threaded part 3 or the internal threaded part 4.

[0039] In this embodiment, from the perspective of connection strength, the external threaded part 3 and the internal threaded part 4 are connected by internal threads in the through hole 5. Compared with the traditional riveting method, the threaded connection provides a more stable and continuous fastening force, effectively avoiding loosening caused by external impact or vibration. The groove 6's design for accommodating the cap structure ensures the compactness of the connection structure, avoids interference or friction between protruding parts and other equipment parts, reduces wear, and extends the overall service life of the equipment. On the other hand, the groove 6 provides a stable support environment for the cap structure, solving the problem of the rivet end easily bending and deforming due to lack of support in the traditional riveting method, greatly enhancing the reliability of the connection. Even when the belt 1 is subjected to a large load and frequent bending operations, the cap structure accommodated in the groove 6 can maintain a tight state, effectively preventing the steel rod from loosening and detaching, ensuring that the belt 1 and the connecting part 2 always maintain a stable connection, thus providing a solid guarantee for the stable operation of the relevant mechanical equipment.

[0040] like Figure 3 As shown, this is a specific embodiment of the belt connection structure provided in this example. The groove 6 is a rectangular groove, and the groove 6 has at least one through hole 5.

[0041] Specifically, the regular shape of the rectangular groove facilitates manufacturing and ensures the dimensional accuracy and consistency of the groove 6, thus providing a stable foundation for subsequent installation and connection. Since the groove 6 has at least one through hole 5, the connection point between the belt 1 and the connector 2 can be flexibly arranged according to actual needs. When it is necessary to withstand larger tensile or shear forces, the number of through holes 5 can be increased, and multiple fasteners can be used to distribute the force, improving the reliability and stability of the connection.

[0042] Furthermore, the shape of the groove 6 in this embodiment is not limited to a rectangular shape. In fact, as long as the shape of the groove 6 meets the key condition of accommodating the fastener's cap structure and ensuring that the fastener's cap structure does not exceed the depth of the groove 6, thus avoiding any protrusion from the surface of the belt 1, it is acceptable. In this way, in practical applications, the shape of the groove 6 can be flexibly selected or designed according to specific design requirements and operating conditions, providing more possibilities and adaptability for the belt connection structure to better meet the diverse requirements of different equipment and working scenarios.

[0043] like Figure 4 As shown, this is a specific embodiment of the belt connection structure provided in this embodiment. The internal threaded component 4 includes a base plate 7, which is embedded in the groove 6. The base plate 7 has at least one protrusion 8, which is inserted into the through hole 5 of the belt 1. The protrusion 8 has an internal threaded hole 9, which is used to connect with the external threaded component 3.

[0044] Specifically, the substrate 7 is embedded in the groove 6, ensuring a stable connection between the internal threaded component 4 and the belt 1, preventing displacement of the internal threaded component 4 due to vibration or other factors during belt 1 operation. At least one protrusion 8 on the substrate 7 is precisely inserted into the through hole 5 of the belt 1, serving a positioning and initial fixing function, making the relative position of the internal threaded component 4 and the belt 1 more accurate and stable. When the external threaded component 3 is screwed into the internal threaded hole 9, the two fit tightly together, forming a reliable threaded connection. This connection method can withstand greater tensile and shear forces.

[0045] like Figure 1 As shown, this is a specific embodiment of the belt connection structure provided in this example, wherein the groove 6 has at least two through holes 5.

[0046] Specifically, multiple through holes 5 allow the belt 1 and the connector 2 to form multiple connection points, evenly distributing the tensile and impact forces on the belt 1 during operation, preventing excessive stress at a single point, and greatly enhancing the reliability and stability of the connection. At the same time, this design is highly flexible. The number of through holes 5 can be selected as needed for different working scenarios and stress conditions. Under heavy loads, multiple through holes 5 strengthen the connection; under light stress, the number of through holes 5 can be reduced, simplifying installation and maintenance. Furthermore, the layout of the through holes 5 can be optimized according to the force direction and stress distribution of the belt 1, improving overall performance, ensuring stable operation of the belt 1, extending its service life, reducing equipment failure and downtime, and improving operating efficiency and production benefits.

[0047] like Figure 4 As shown, this is a specific implementation of the belt connection structure provided in this embodiment. The internal threaded component 4 includes a base plate 7 and at least two protrusions 8 disposed on the base plate 7.

[0048] Specifically, the base plate 7 is embedded in the groove 6, providing a stable support platform for the entire internal threaded component 4, effectively preventing displacement or shaking of the internal threaded component 4 during the operation of the belt 1. The protrusion 8 is inserted into the through hole 5 of the belt 1, and the protrusion 8 has an internal threaded hole 9, which is used to connect with the external threaded component 3, realizing multi-point positioning and connection. This not only enhances the mechanical bonding force between the internal threaded component 4 and the belt 1, but also allows the belt 1 to evenly distribute the force when subjected to complex external forces such as tension and torque through multiple protrusions 8.

[0049] like Figure 4 As shown, this is a specific implementation of the belt connection structure provided in this embodiment, wherein the root of the protruding post 8 has a tapered section 10.

[0050] Specifically, during installation, the tapered section 10 acts as a guide. When the external threaded part 3 is connected to the internal threaded hole 9 in the protrusion 8, the tapered section 10 can help the external threaded part 3 to align more accurately with the internal threaded hole 9, reducing the difficulty of alignment during installation. This guiding effect is more obvious, especially in situations where space is narrow or operation is inconvenient, making the installation process smoother and more efficient.

[0051] like Figure 5 , Figure 6 As shown, this is a specific implementation of the belt connection structure provided in this embodiment, wherein the average diameter of the tapered segment 10 is greater than the inner diameter of the through hole 5 of the belt 1.

[0052] Specifically, when the protrusion 8 is inserted into the through hole 5 of the belt 1, the presence of the tapered section 10 will cause the protrusion 8 to gradually form an interference fit in the through hole 5, so that the internal threaded part 4 can maintain a fixed position during the mating process of the external threaded part 3 and the internal threaded part 4. This facilitates the installation process of the connection structure and can effectively prevent the protrusion 8 from loosening or shifting due to vibration, tension and other factors during the operation of the belt 1. This ensures the stability of the connection between the internal threaded part 4 and the belt 1, thereby improving the reliability of the entire belt connection structure.

[0053] like Figure 2 As shown, this is a specific implementation of the belt connection structure provided in this embodiment, wherein the height of the protrusion 8 is less than the depth of the through hole 5 of the belt 1.

[0054] Specifically, during the use of belt 1, the thickness of belt 1 may change due to factors such as tension and temperature variations. The height of the protrusion 8 being less than the depth of the through hole 5 can accommodate this thickness change to a certain extent, preventing the fit between the protrusion 8 and belt 1 from being too tight or too loose due to slight changes in the thickness of belt 1, thus ensuring the stability and reliability of the connection.

[0055] like Figure 2 As shown, this is a specific embodiment of the belt connection structure provided in this example. The groove 6 has a plurality of grooves spaced apart along the length direction of the belt 1.

[0056] Specifically, when the tension and torque on the belt 1 vary at different locations, fasteners can be flexibly installed at the grooves 6 in different positions according to the force distribution. For example, at critical parts of the belt 1 drive where the force is greater, connection points can be added at the corresponding grooves 6 to strengthen the connection and prevent breakage or loosening.

[0057] like Figure 1 As shown, this embodiment provides a specific implementation of a tomato harvester, including the aforementioned belt connection structure.

[0058] Specifically, when the harvester moves in the field, bumps and vibrations are inevitable. The conical section 10 and protruding post 8 in the groove 6 are tightly connected to the belt 1, effectively resisting the effects of vibration, preventing the internal and external threaded parts 3 from loosening, and ensuring the stability of the connection. At the same time, the height of the protruding post 8 is less than the depth of the through hole 5 of the belt 1, allowing the belt 1 to deform freely to a certain extent, adapting to the working conditions of the equipment under different terrains, reducing damage to the belt 1 caused by abnormal stress, improving the working efficiency of the tomato harvester, and ensuring the smooth progress of the entire harvesting operation.

[0059] Working principle:

[0060] The base plate 7 of the internally threaded component 4 is securely embedded in the groove 6 of the belt 1, and at least two protrusions 8 on the base plate 7 are inserted into the through hole 5 of the belt 1. The externally threaded component 3 is screwed into the internally threaded hole 9 of the protrusion 8 to achieve a tight connection. During operation, the external forces such as tension, torque, and vibration borne by the belt 1 are evenly distributed by the multiple spaced grooves 6 and the multiple protrusions 8 connection points in each groove 6. The tapered section 10 at the root of the protrusion 8 serves as a guide during installation and forms an interference fit after installation to prevent loosening. The height of the protrusion 8 is less than the depth of the through hole 5 of the belt 1, so that the belt 1 is not excessively restricted when deformed, reducing stress concentration. The multiple spaced grooves 6 also facilitate the adjustment of the connection points as needed and the quick positioning and maintenance during maintenance, thereby ensuring that the belt 1 connection is stable and reliable and adaptable to various working conditions.

[0061] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of the present invention.
