Description

Technical Field

[0001] This application relates to the field of straw wrapping technology, and more particularly to a tensile-strength reinforced straw wrapping. Background Technology

[0002] The primary function of hay bales is to solidify loose hay, straw, silage, and other materials into bales, such as round or square bales. However, loose materials themselves have no fixed shape, and the integrity of the bales is maintained entirely by the "tensile force constraint" of the bale. During the wrapping process, the bale is easily torn or broken by the expansion force of the material, resulting in loose bales that cannot form standard bales. Even if the bales are temporarily formed, slight displacement between materials during transportation or stacking will continue to exert tensile force on the bale. Insufficient tensile strength will cause the mesh to enlarge and the edges to tear, ultimately leading to the scattering of hay and straw and resulting in material loss.

[0003] In existing technologies, the bottom breakage of hay bales designed with uniform density is not accidental when used with forklifts, cranes, and other equipment for lifting hay bales. Rather, it is an inevitable result of a severe mismatch between the stress characteristics of the net and the lifting mechanical environment. The core contradiction lies in the fact that the uniform density net cannot specifically resist the instantaneous concentrated tension in the middle and lifting points during the lifting process. This ultimately causes the tension overload point to shift to the bottom and lead to breakage. When forklifts or cranes lift hay bales, the weight of the hay bales themselves is converted into a vertically downward tension through the net. The distribution of this tension is significantly non-uniform—the middle and lifting points are the absolute core areas of tension, and the bottom net must additionally bear the dual load of stacking pressure and dynamic impact.

[0004] Therefore, it is necessary to propose a tensile-strength-enhanced straw net to solve the above problems. Utility Model Content

[0005] This application provides a tensile-strength reinforced hay bale net to improve the technical problem in related technologies where hay bales designed with an overall uniform density may break at the bottom when used with forklifts, cranes, or other equipment to lift hay bales.

[0006] This application provides a tensile-enhanced straw bale net, comprising a mesh structure formed by multiple warp and weft threads interwoven together. The mesh structure has at least two regions with different mesh densities along its length, wherein the mesh density of the first region is greater than that of the second region. The mesh density of the first region is located in the middle part of the mesh structure, so that the straw bale net exerts different constraint forces on the straw bale in different regions, thereby improving the overall binding stability of the straw bale. A connecting component is provided at one end of the mesh structure to facilitate fixing the two ends of the straw bale and to provide a lifting point corresponding to the position of the second region.

[0007] The technical solution described above in this application embodiment has at least the following technical effects: by designing a high grid density in the middle first region and a low grid density in the other second regions, the constraint force is directionally distributed. At the same time, the lifting point corresponds to the second region, which can indirectly reduce the additional tension interference in the first region and reduce the probability of breakage in the middle region and the bottom from the force path.

[0008] In this embodiment, the mesh structure is provided with three regions of different densities. The mesh density of the first region is greater than that of the second region, the mesh density of the second region is greater than that of the third region, the second region is located at both ends of the first region, and the third region is located at one end of the second region away from the first region.

[0009] Through this technical solution, the straw bale netting constructs a three-layer force-bearing system of "core reinforcement, transition buffer, and edge adaptation" by using a gradient density design of the first region (high density), the second region (medium density), and the third region (low density). Compared with traditional uniform density netting or dual density netting, it more accurately matches the force reduction law of the straw bale from the core to the edge.

[0010] In this embodiment, the connecting assembly includes a fixed frame and a locking claw rotatably mounted on the fixed frame. The locking claw is a plurality of semi-circular rings arranged in parallel. The fixed frame and the locking claw are mutually engaged through connecting holes and locking blocks. The fixed frame is also provided with a transmission component for releasing the engagement relationship between the locking claw and the fixed frame.

[0011] With this technical solution, when it is necessary to fix both ends of the straw net, the end of the straw net away from the connecting component is placed in the locking claw. By fastening the locking claw, the snap-fit ​​block on the locking claw is engaged with the connecting hole on the fixing frame, restricting the movement between the two and making it easier to fix both ends of the straw net.

[0012] In this embodiment, the transmission groove is connected to the connecting hole, the transmission component includes a transmission rod, the transmission rod is movably disposed in the transmission groove, and the transmission rod is provided with an abutment block for abutting against the locking block to release the locking relationship between the locking block and the connecting hole.

[0013] This technical solution allows for the release of the locking pawl from the fixed frame by pressing the transmission rod, which in turn facilitates the transmission between the abutment block and the locking block on the transmission rod. This release method is more convenient.

[0014] In this embodiment, a retaining spring is also provided on the end of the transmission rod near the transmission groove to help the transmission rod return to its original position.

[0015] This technical solution optimizes the unlocking system of the transmission groove, transmission rod, and abutment block by setting a stop spring at the end of the transmission rod near the transmission groove. Its core function is to realize the automatic return of the transmission rod after unlocking by using the elastic reset characteristics of the spring. This makes up for the shortcomings of the springless design, which requires manual reset, is prone to leaving unlocked state, and affects the next fixation. It further improves the closed-loop operation process of fixing, unlocking and resetting.

[0016] In this embodiment, a transmission pressure block is also provided on the end of the transmission rod away from the abutment spring.

[0017] This technical solution places the transmission rod inside the fixed frame in a semi-enclosed state, making it less prone to damage while optimizing the user's usage and providing a better manual experience.

[0018] In this embodiment, the fixed frame is also equipped with a conveyor belt to facilitate transportation via the conveyor belt.

[0019] This technical solution uses a conveyor belt to clearly define the points of application for lifting during transportation, avoiding lifting from other locations that could cause the straw netting to break due to density differences. Attached Figure Description

[0022] In existing technologies, the bottom breakage of hay bales designed with uniform density is not accidental when used with forklifts, cranes, and other equipment for lifting hay bales. Rather, it is an inevitable result of a severe mismatch between the stress characteristics of the net and the lifting mechanical environment. The core contradiction lies in the fact that the uniform density net cannot specifically resist the instantaneous concentrated tension in the middle and lifting points during the lifting process. This ultimately causes the tension overload point to shift to the bottom and lead to breakage. When forklifts or cranes lift hay bales, the weight of the hay bales themselves is converted into a vertically downward tension through the net. The distribution of this tension is significantly non-uniform—the middle and lifting points are the absolute core areas of tension, and the bottom net must additionally bear the dual load of stacking pressure and dynamic impact.

[0023] Based on this, in order to improve the technical problem that the bottom of the hay bale may break when the hay bale is lifted by a forklift, crane or other equipment in the related technology, the embodiments of this application provide the following solution.

[0024] Please refer to the following: Figures 1 to 6 This application provides a tensile-enhanced straw bale net, which includes a mesh structure 1 formed by multiple warp and weft threads interwoven together. The mesh structure 1 has at least two regions with different mesh densities along its length, wherein the mesh density of the first region 11 is greater than that of the second region 12. The mesh density of the first region 11 is located in the middle part of the mesh structure 1, so that the straw bale net exerts different constraints on the straw bale in different regions, thereby improving the overall binding stability of the straw bale. A connecting component 2 is provided on one end of the mesh structure 1 to facilitate fixing the two ends of the straw bale and to provide a lifting point corresponding to the position of the second region 12.

[0025] The tensile-enhanced hay bale net provided in this application embodiment addresses the issue that the central area is the core region where tensile and compressive forces are most concentrated during hay bale packing, hoisting, and stacking. During hoisting, the central area needs to bear the weight of the majority of the hay bales, and during stacking, it needs to withstand the vertical pressure of the upper hay bales. Meanwhile, the edge areas only need basic constraint forces to prevent hay from scattering. This hay bale net achieves directional distribution of constraint forces through the design of a high-mesh density in the central first area 11 and a low-mesh density in the other areas, the second area 12. At the same time, the lifting point corresponds to the second area 12, which can indirectly reduce the additional tensile interference in the first area 11. During hoisting, the tensile force is transmitted to the second area 12 and then to the entire hay bale through the connecting component 2. The central first area 11 only needs to bear the pressure generated by the weight of the hay bale itself and does not need to bear the instantaneous impact force of hoisting and lifting, thus reducing the probability of breakage in the central area and the bottom from the force path.

[0026] In this embodiment, the mesh structure 1 is provided with three regions of different densities. The mesh density of the first region 11 is greater than that of the second region 12. The mesh density of the second region 12 is greater than that of the third region 13. The second region 12 is located at both ends of the first region 11, and the third region 13 is located at one end of the second region 12 away from the first region 11.

[0027] This design, through a gradient density structure of three zones—region 11 (high density), region 12 (medium density), and region 13 (low density)—constructs a three-layer stress-bearing system: core reinforcement, transition buffering, and edge adaptation. Compared to traditional uniform-density or dual-density nets, this design more accurately matches the decreasing stress distribution from the core to the edge of the bale. Compared to traditional uniform-density or dual-density nets, the three-density zone design focuses on "precision" and "balance," achieving comprehensive breakthroughs in safety, adaptability, and economy. The high-density design of region 11 instantly increases the tensile strength of the core area, enabling it to withstand extreme scenarios such as sudden braking during hoisting and heavy stacking pressure, reducing the risk of core breakage. The buffering effect of region 12 eliminates stress abrupt changes from the core to the edge, avoiding the common boundary breakage problem in dual-density nets, thus reducing the overall breakage rate of the net. The flexible design of region 13 reduces frictional damage between the edges and the hay or machinery, decreasing the probability of edge cracking and further extending the lifespan of the net.

[0028] In this embodiment, the connecting component 2 includes a fixed frame 21 and a locking claw 22 rotatably mounted on the fixed frame 21. The locking claw 22 is a plurality of semi-circular rings arranged in parallel. The fixed frame 21 and the locking claw 22 are mutually engaged through a connecting hole 23 and a snap-fit ​​block 24. A transmission component 25 is also provided inside the fixed frame 21 to release the snap-fit ​​relationship between the locking claw 22 and the fixed frame 21.

[0029] With this configuration, when both ends of the straw net need to be fixed, the end of the straw net furthest from the connecting component 2 is placed in the locking claw 22. By fastening the locking claw 22, the locking block 24 on the locking claw 22 is engaged with the connecting hole 23 on the fixing frame 21, restricting movement between the two and making it easier to fix both ends of the straw net. Thus, the mechanical cooperation between the locking claw 22 clamping the end of the straw net and the locking block 24 engaging with the connecting hole 23 provides a precise positioning, quick locking, and stable limiting solution for fixing both ends of the straw net, solving the problems of cumbersome operation, loose fixing, and easy detachment caused by traditional fixing methods.

[0030] In this embodiment, the transmission groove 251 is connected to the connecting hole 23. The transmission component 25 includes a transmission rod 252, which is movably disposed in the transmission groove 251. An abutment block 253 is provided on the transmission rod 252 for abutting against the locking block 24 to release the locking relationship between the locking block 24 and the connecting hole 23.

[0031] With this configuration, by pressing the transmission rod 252, the locking claw 22 and the fixing frame 21 are released through the transmission between the abutment block 253 and the locking block 24 on the transmission rod 252. The release method is more convenient. Thus, its core function is to precisely release the locking claw 22, the locking block 24 and the fixing frame 21 connection hole 23 through mechanical transmission when the straw net needs to be disassembled. This makes up for the shortcomings of traditional fixing methods, such as difficulty in unlocking and easy damage to the net, and forms a closed loop from quick fixing to convenient unlocking.

[0032] In this embodiment, a retaining spring 254 is also provided on one end of the transmission rod 252 near the transmission groove 251 to help the transmission rod 252 return to its original position.

[0033] This configuration, with an abutment spring 254 at the end of the transmission rod 252 near the transmission groove 251, optimizes the unlocking system of the transmission groove 251, transmission rod 252, and abutment block 253. Its core function is to automatically return the transmission rod 252 to its original position after unlocking by using the elastic reset characteristic of the spring. This overcomes the shortcomings of springless designs, such as the need for manual reset, the tendency to retain the unlocked state, and the impact on the next fixation, and further improves the closed-loop operation process of fixing, unlocking, and resetting.

[0034] In this embodiment, a transmission pressure block 255 is also provided on the end of the transmission rod 252 away from the abutment spring 254.

[0035] This design places the transmission rod 252 inside the fixed frame 21 in a semi-enclosed state, making it less prone to damage while optimizing the user's operation and providing a better manual experience. This addresses the pain points of blockless designs, such as difficult operation, slippage, and accidental activation, by increasing the operating contact area, optimizing force transmission efficiency, and improving operational safety. It makes unlocking easier and more controllable, further perfecting the closed-loop experience of fixing, unlocking, and resetting.

[0036] In this embodiment, a conveyor belt 26 is also provided on the fixed frame 21 to facilitate transportation via the conveyor belt 26.

[0037] This design, through the conveyor belt 26, clearly defines the lifting points required during transportation, preventing breakage caused by density differences in the straw netting due to lifting from other locations. Thus, by pre-setting and clearly defining the lifting points during transportation, the conveyor belt 26 directly solves the problem of netting breakage caused by arbitrary lifting in traditional transport from the perspective of force path control, and is particularly suitable for the gradient density design of straw netting.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
