Description

Technical Field

[0001] The utility model relates to the technical field of ropes for grain reels, in particular to a rope for grain reels. Background Art

[0002] The grain rolling machine, also known as the flattening machine, is a device used to flatten the grain after it is stored in the warehouse. As we all know, after the grain is mechanized into the warehouse, a cone-shaped grain pile will be formed at the center of the cylindrical silo and multiple locations in the bunk silo. This cone-shaped grain pile is extremely unfavorable to the safety of grain storage. The flatness of the grain surface is directly related to the implementation effect of grain storage technologies such as ventilation, fumigation, and grain temperature measurement and control during grain storage, which in turn affects the safety of grain during the storage period. Therefore, flattening the grain surface is crucial as the last operation link before the grain enters the conventional storage stage after entering the warehouse. The utility model patent with the authorization announcement number CN214482326U discloses an efficient and simple flattening machine, in which the wire rope is driven by a motor, and then the flattening plate is driven to operate. The disadvantage of pure wire rope is that since it is used for operations on grain, the wire rope cannot be oiled, which makes it easy to rust, wear and break, and has a lot of noise. Utility Model Content

[0003] The utility model aims to provide a rope for a grain reel, aiming to improve the problems of greater wear and poor mute effect of pure steel wire ropes used in existing grain reels.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A rope for a grain winding machine comprises a rope core and rope strands. With the rope core as the center, a plurality of rope strands are spirally twisted and evenly distributed on the surface of the rope core. The rope strands are wrapped with a first sleeve made of polyurethane material. The gap between the first sleeve and the rope strands is filled with a plurality of filling strands. The filling strands are spirally twisted and located between adjacent rope strands. The rope strands are made of polyethylene fiber, and the filling strands are made of seaweed fiber.

[0006] Preferably, the diameter of the filling strand is smaller than the diameter of the rope strand, and the diameter of the rope strand is smaller than the diameter of the rope core.

[0007] Preferably, the twist of the rope strands is less than 5 twists per 10 cm length.

[0008] Preferably, the rope core comprises a steel core and strands, with the steel core as the center, a plurality of strands are spirally twisted and evenly distributed on the surface of the steel core, and the strands are wrapped with a second sleeve made of polyurethane.

[0009] Preferably, the periphery of the strand and the accommodating cavity of the second sleeve are filled with a rubber filling layer.

[0010] Preferably, the strands are made of polyethylene fiber.

[0011] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0012] 1. In the utility model, with the rope core as the center, a number of rope strands are spirally twisted and evenly distributed on the surface of the rope core to form a strand shape, and then wrapped with a sleeve made of polyurethane material, which has good energy absorption, shock absorption, noise reduction and wear resistance, which not only increases the service life of the rope, but also reduces the noise generated during its operation.

[0013] 2.

[0022] Example

[0023] Please refer to Figure 1 As shown, this embodiment provides a rope for a grain winding machine, including a rope core 1 and rope strands 2. With the rope core 1 as the center, a plurality of rope strands 2 are spirally twisted and evenly distributed on the surface of the rope core 1. The rope strands 2 are wrapped with a first sleeve 4 made of polyurethane material. The gap between the first sleeve 4 and the rope strands 2 is filled with a plurality of filling strands 3. The filling strands 3 are spirally twisted and located between adjacent rope strands 2. The rope strands 2 are made of polyethylene fiber, and the filling strands 3 are made of seaweed fiber.

[0024] Specifically, with the rope core 1 as the center, a certain number of rope strands 2 are twisted into a spiral rope, and the rope strands 2 are wrapped with a first sleeve 4. The wall thickness of the first sleeve 4 is 2-3mm, and the material of the sleeve is polyurethane. Since polyurethane has the characteristics of high wear resistance, impact resistance, high bearing capacity, acid and alkali resistance, the sleeve has less wear during use, and has higher toughness, tear resistance and corrosion resistance, which increases the service life of the rope. In addition, compared with the "hard collision" of pure steel wire rope during use, the polyurethane sleeve has the advantages of energy absorption, shock absorption and noise reduction.

[0025] At the same time, a number of filling strands 3 are filled in the gap between the first sleeve 4 and the rope strand 2, so that the rope structure is more stable, fuller and more uniform in thickness, and it is not easy to leave gaps in the sleeve and cause inward collapse. Since the filling strands 3 are made of seaweed fiber, they have good antibacterial, anti-mildew and anti-mite effects, thereby increasing the service life of the rope.

[0026] In addition, the rope strands 2 are made of polyethylene fibers, which have the characteristics of high strength, small elongation, light weight, wear resistance, and easy operation. In a preferred embodiment, the polyethylene fibers are dipped in glue (such as modified chloroprene rubber) before making the rope strands 2, and the glue content is about 5-7%. After the dipping, the breaking strength of the polyethylene fibers is increased to varying degrees.

[0027] Furthermore, the diameter of the filling strand 3 is smaller than the diameter of the rope strand 2, and the diameter of the rope strand 2 is smaller than the diameter of the rope core 1. Specifically, the filling strand 3 has a smaller diameter so that the gap can be effectively filled, and the diameter of the rope core 1 is the largest, which facilitates the twisting of the rope strand 2 and reduces the gap between the rope strands 2, making the twisting more compact and improving the overall structural strength of the rope.

[0028] Furthermore, the twist of the rope strand 2 is less than 5 twists per 10 cm length. Specifically, the greater the fiber twist, the lower the fiber breaking strength. Therefore, in order to achieve a certain breaking strength when making the rope strand 2, the twist is less than 5 twists per 10 cm length. At this time, the effect of the twist on the breaking strength of the fiber is small and can be ignored, thereby increasing the overall structural strength of the rope.

[0029] like Figure 2 As shown, the rope core 1 includes a steel core 11 and strands 12. With the steel core 11 as the center, a number of strands 12 are spirally twisted and evenly distributed on the surface of the steel core 11. The strands 12 are wrapped with a second sleeve 14 made of polyurethane. Specifically, the rope core 1 is a steel core 11, which makes the rope have a certain rigidity and high structural stability, avoiding the rope from being entangled and affecting the use. At the same time, with the steel core 11 as the center, a certain number of strands 12 are twisted into a spiral rope, which increases the service life of the rope as a whole. The second sleeve 14 wrapped with polyurethane material provides a certain buffer between the rope core 1 and the strands 2, which is wear-resistant and can effectively reduce shock during use.

[0030] Furthermore, the outer periphery of the strand 12 and the accommodating cavity of the second sleeve 14 are filled with a rubber filling layer 13. The rubber filling layer 13 is obtained by dipping the rope core 1 in rubber. In this embodiment, chloroprene rubber is used, which has high tensile strength and good aging resistance, and can meet the long-term winding use of the rope. The addition of the rubber layer 13 makes the rope strand 2 structure fuller and stronger, and improves the high strength, wear resistance, corrosion resistance, elasticity and light weight of the rope. At the same time, due to the presence of the rubber layer 13, the rope has better elasticity, and can be adaptively deformed during the winding process. Compared with the purely rigid steel wire rope, it is less likely to have a stringing phenomenon.

[0031] In another preferred embodiment, the strand 12 is made of polyethylene fiber with a fiber strength of 30 cN / dtex-50 cN / dtex, which ensures high strength of the rope while having good wear resistance and corrosion resistance, and makes the rope lighter.

[0032] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
