Description

Technical Field

[0001] This utility model belongs to the field of baling machines, and specifically relates to a welded steel needle for baling machines. Background Technology

[0002] Straw balers rely on needle mechanisms to perform baling operations, which act as ropes to bind the straw. The needles themselves have complex shapes and holes. Current methods typically involve casting followed by necessary machining. However, casting suffers from problems such as large deformation, low precision, high scrap rate, low strength, and difficulties in subsequent processing, resulting in a short service life and increased equipment costs. Utility Model Content

[0003] This invention provides a welded steel needle for a baler, which addresses the shortcomings described in the prior art.

[0004] The technical solution adopted in this utility model is as follows: A welded steel needle for a baler includes a needle body comprising a first arc-shaped side plate, a second arc-shaped side plate, a first reinforcing plate, and a second reinforcing plate. The first and second arc-shaped side plates are arranged opposite each other, and the first and second reinforcing plates are welded parallel to each other between them. The heads of the first and second arc-shaped side plates are close to each other to form a needle tip. A rope-passing hole is provided between the heads of the first and second reinforcing plates and the needle tip. The roots of the first and second arc-shaped side plates are welded to a needle base. The second reinforcing plate, the first arc-shaped side plate, and the second arc-shaped side plate form a guide wire groove. This invention uses a combined welding method instead of the original one-piece casting method, reducing manufacturing costs. Maintenance can be performed by replacing individual parts, eliminating the need to replace the entire cast part, thus reducing maintenance costs.

[0005] As a preferred embodiment of this utility model, a needle seat limiting platform is provided at the root of the first arc-shaped side plate and the root of the second arc-shaped side plate of the steel needle. The end of the needle seat is located at the needle seat limiting platform and welded to the end face of the needle seat limiting platform. The needle seat limiting platform is formed by removing a portion of the root of the first arc-shaped side plate and the root of the second arc-shaped side plate of the steel needle to create a step. The end of the needle seat is assembled to the step and welded to the end face of the step.

[0006] In a preferred embodiment of this invention, the roots of the first and second arc-shaped side plates of the steel needle are welded to the same welding reinforcing block, which is then welded to the needle holder. To enhance the welding strength between the needle holder and the needle holder, end-face welding is performed using the welding reinforcing block, thereby improving the welding strength between the needle holder and the steel needle body.

[0007] As a preferred embodiment of this utility model, the first arc-shaped side plate of the steel needle is provided with a first positioning welding hole I and a second positioning welding hole II along the arc direction; the second arc-shaped side plate of the steel needle is provided with a first positioning welding hole II and a second positioning welding hole II along the arc direction; the first reinforcing plate of the steel needle is provided with a first welding protrusion, and the corresponding first welding protrusion is inserted into the first positioning welding hole I and the first positioning welding hole II before welding; the second reinforcing plate of the steel needle is provided with a second welding protrusion, and the corresponding second welding protrusion is inserted into the second positioning welding hole I and the second positioning welding hole II before welding. The provision of positioning welding holes and welding protrusions not only facilitates accurate assembly, but also prevents movement during welding, thereby improving welding accuracy.

[0008] As a preferred embodiment of this utility model, the first reinforcing plate of the steel needle is flush with the upper surface of the first arc-shaped side plate and the second arc-shaped side plate of the steel needle.

[0009] As a preferred embodiment of this utility model, the head of the second reinforcing plate of the steel needle is inclined toward the first reinforcing plate of the steel needle.

[0010] In a preferred embodiment of this invention, a first rope roller and a second rope roller are welded to the tip of the steel needle. The gap between the first and second rope rollers serves as a rope threading hole, and the second rope roller is located near the first reinforcing plate of the steel needle. Both rope rollers have arc surfaces to prevent the bundling rope from being worn off during operation.

[0011] As a preferred embodiment of this utility model, the second rope roller is a pulley, and the area defined by the outer arc surface of the pulley, the outer circumferential surface of the first rope roller, the inner side of the first arc-shaped side plate of the steel needle, and the inner side of the second arc-shaped side plate of the steel needle is a rope threading hole.

[0012] As a preferred embodiment of this utility model, the first arc-shaped side plate of the steel needle, the second arc-shaped side plate of the steel needle, the first reinforcing plate of the steel needle, and the second reinforcing plate of the steel needle are all spring steel plates.

[0013] This invention uses a combination of welding to manufacture steel needles and spring steel plates. Spring steel plates have high strength and toughness, and can automatically repair themselves after a certain deformation. Compared with cast steel needles, this reduces the loss rate, and the overall weight is lower, resulting in smoother operation of the steel needles and lower manufacturing costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] A type of baler uses welded steel needles, such as Figure 1-3 As shown, the device includes a steel needle body, which comprises a first arc-shaped side plate 101, a second arc-shaped side plate 102, a first reinforcing plate 103, and a second reinforcing plate 104. The first arc-shaped side plate 101, the second arc-shaped side plate 102, the first reinforcing plate 103, and the second reinforcing plate 104 are all made of spring steel plate.

[0026] like Figure 1-4 As shown, the first arc-shaped side plate 101 and the second arc-shaped side plate 102 of the steel needle are both arc-shaped plates with the same structure and shape, and are arranged opposite each other as basic side plates. The first reinforcing plate 103 and the second reinforcing plate 104 of the steel needle are welded parallel to each other along the height direction between the first arc-shaped side plate 101 and the second arc-shaped side plate 102 of the steel needle.

[0027] To facilitate assembly and welding, the first arc-shaped side plate 101 of the steel needle is provided with a first positioning welding hole I and a second positioning welding hole I along the arc direction; the second arc-shaped side plate 102 of the steel needle is provided with a first positioning welding hole II and a second positioning welding hole II along the arc direction; as shown Figure 5 As shown, the first reinforcing plate 103 of the steel needle is provided with a first welding protrusion. The corresponding first welding protrusions are inserted into the first positioning welding hole I and the first positioning welding hole II, and then welded. Figure 6 As shown, the second reinforcing plate 104 of the steel needle is provided with a second welding protrusion. The corresponding second welding protrusion is inserted into the second positioning welding hole I and the second positioning welding hole II before welding. The positioning welding holes and welding protrusions not only facilitate accurate assembly, but also prevent movement during welding, thus improving welding accuracy.

[0028] The first reinforcing plate 103 and the second reinforcing plate 104 of the steel needle are also arc-shaped and welded to the two side plates along the arc direction. The first reinforcing plate 103 of the steel needle is flush with the upper end face of the first arc-shaped side plate 101 and the second arc-shaped side plate 102 of the steel needle. The welding position of the second reinforcing plate 104 of the steel needle does not exceed the first arc-shaped side plate 101 and the second arc-shaped side plate 102 of the steel needle. Therefore, the second reinforcing plate 104, the first arc-shaped side plate 101 and the second arc-shaped side plate 102 of the steel needle form the wire groove 4.

[0029] The heads of the first arc-shaped side plate 101 and the second arc-shaped side plate 102 of the steel needle are close to each other to form the needle tip; the heads of the first reinforcing plate 103 and the second reinforcing plate 104 of the steel needle are at a certain distance from the needle tip, such as... Figure 9 As shown, a first rope roller 6 and a second rope roller 7 are welded to the tip of the steel needle. Due to the spacing of the steel needle tips, the first rope roller 6 can only be a round roller. The two ends of the round roller are directly welded to the head of the first arc-shaped side plate 101 and the head of the second arc-shaped side plate 102 of the steel needle. The second rope roller 7 mainly serves to feed the rope. The second rope roller 7 is located near the first reinforcing plate 103 of the steel needle. It is preferable to use a pulley. The outer arc surface of the pulley and the outer circumference of the first rope roller are the main contact surfaces with the bundling rope to reduce friction and prevent the bundling rope from being worn off. The area defined by the outer arc surface of the pulley, the outer circumference of the first rope roller, the inner side of the first arc-shaped side plate 101 of the steel needle, and the inner side of the second arc-shaped side plate 102 of the steel needle is the rope hole 2. The head of the second reinforcing plate 104 of the steel needle is inclined toward the first reinforcing plate 103 of the steel needle so that the head of the guide groove 4 will not obstruct the bundling rope from entering the guide groove.

[0030] like Figure 7 and 8As shown, the roots of the first arc-shaped side plate 101 and the second arc-shaped side plate 102 of the steel needle are welded to the needle holder 3; in this embodiment, a needle holder limiting platform is provided at the roots of the first arc-shaped side plate 101 and the second arc-shaped side plate 102 of the steel needle, such as... Figure 4 As shown, the needle seat limiting platform is formed by removing a portion of the root of the first arc-shaped side plate 101 and the root of the second arc-shaped side plate 102 of the steel needle to create a step. The end of the needle seat 3 is located on the needle seat limiting platform and welded to the end face of the needle seat limiting platform.

[0031] To enhance the welding strength of the needle holder, end face welding is performed using a welding reinforcement block to improve the welding strength between the needle holder and the steel needle body. The root of the first arc-shaped side plate 101 and the root of the second arc-shaped side plate 102 of the steel needle are welded to the same welding reinforcement block 5, and the welding reinforcement block 5 is welded to the needle holder 3.

[0032] This invention uses a combined welding method to replace the original one-piece casting method, which reduces manufacturing costs. Maintenance can be performed by replacing individual parts instead of replacing the entire casting, thus reducing maintenance costs.
