[0036] Reference Figures 1-3 This is the first embodiment of the present invention, which proposes a forage turning and drying blade shaft for use in a forage turning and drying machine. It includes a central shaft 1, which is rotatably mounted inside the forage turning and drying machine; a number of support plates 2, which are mounted on the central shaft 1 and have gaps between adjacent support plates 2; a number of mounting plates 3, which are mounted on the support plates 2 and are evenly distributed along the circumference of the central shaft 1; and a number of elastic grass-pulling components 4, which are mounted on the mounting plates 3.

[0037] In this embodiment, to address the problem of heavy and difficult-to-install blade shafts in related technologies, a forage turning blade shaft is designed. The central shaft 1 is made of high-strength alloy steel and is rotatably mounted on the frame of the forage turning machine via bearing seats, ensuring flexible rotation and the ability to withstand large loads. Multiple support plates 2, made of aluminum alloy, are evenly welded to the central shaft 1, with adjacent support plates 2 spaced a certain distance apart, ensuring structural strength while reducing overall weight. Multiple mounting plates 3 are made of stainless steel through stamping, with each mounting plate 3 resting on its corresponding support plate 2 at both ends and fixed by welding, achieving even distribution along the circumference of the central shaft 1. Multiple elastic grass-pulling components 4 are made of a highly elastic rubber and steel wire composite material and are fixed to the mounting plates 3 using a specially designed slot structure, with glue applied inside the slots to enhance the fixing effect.

[0038] The advantages are that the high-strength alloy steel central shaft 1 ensures the overall rigidity and durability of the cutter shaft, the aluminum alloy support plate 2 reduces weight without affecting the support performance and is easy to install in the turner, the stainless steel mounting plate 3 is corrosion resistant and easy to install, and the elastic grass-pulling component 4 can effectively turn the grass. This combination design fundamentally solves the problem of the heavy and difficult-to-install cutter shaft, improves installation efficiency, and reduces labor intensity.

[0039] Furthermore, the mounting plate 3 has several positioning grooves 301, and the support plate 2 has several positioning protrusions 201, with the positioning protrusions 201 located within the positioning grooves 301.

[0040] In this embodiment, the mounting plate 3 is provided with a plurality of positioning grooves 301 at the edge in contact with the support plate 2 by a stamping process. The support plate 2 is welded with a size-matched positioning protrusion 201 at the corresponding position. During installation, the positioning protrusion 201 of the support plate 2 is aligned with the positioning groove 301 of the mounting plate 3, and then gently pressed to achieve accurate positioning, and then welded and fixed.

[0041] The advantage is that the cooperation of the positioning groove 301 and the positioning protrusion 201 makes the mounting plate 3 more convenient and fast when mounted on the support plate 2, without the need for complex measurement and adjustment, greatly improving the assembly efficiency, reducing the installation error, ensuring the stability of the whole cutter shaft structure, and further optimizing the problem of difficult installation of the cutter shaft.

[0042] Further, the support plate 2 has a plurality of weight reduction holes 202.

[0043] In this embodiment, the support plate 2 is designed as a circular plate structure, and a plurality of weight reduction holes 202 are processed on the plate surface by a drilling process. The weight reduction holes 202 are uniformly distributed in the edge area of the support plate 2 away from the central shaft 1, which not only ensures the strength of the support plate 2, but also maximally reduces the weight.

[0044] The advantage is that the weight reduction holes 202 effectively reduce the self-weight of the support plate 2, thereby reducing the weight of the whole cutter shaft, making the cutter shaft more labor-saving during installation and handling, and also reducing the energy consumption of the turner, improving the energy utilization efficiency, and facilitating the long-term stable operation of the equipment.

[0045] Further, the elastic grass pushing member 4 has an elastic part 401 arranged on the mounting plate 3, and a grass turning part 402 arranged on the elastic part 401. The elastic part 401 is arranged at both ends of the grass turning part 402 and the mounting plate 3, and is used to provide the force for turning the grass.

[0046] In this embodiment, the elastic part 401 of the elastic grass pushing member 4 is made of high-strength spring steel, and has a spiral shape. One end is welded in the groove of the mounting plate 3, which ensures firm connection. The grass turning part 402 is fixed at the top end of the elastic part 401.

[0047] The advantage is that the spring steel material of the elastic part 401 provides stable and reliable elastic force, which can meet the turning requirements under different working conditions. The nylon material of the grass turning part 402 is light and has a certain flexibility, and is not easy to damage the grass. The combination of the two can efficiently and gently turn the grass during the turning and drying of the grass, improve the turning quality, and ensure the drying effect of the grass.

[0048] Further, the elastic grass pushing member 4 is circumferentially and equidistantly arranged around the central shaft 1.

[0049] In this embodiment, the elastic grass pushing part 4 is uniformly distributed along the circumferential direction and the central axis direction of the central shaft 1, and is fixedly installed on the mounting plate 3 through accurate mold positioning.

[0050] The advantage is that this uniform and reasonable distribution mode ensures that the knife shaft has a wider and more uniform turning and covering range on the grass during rotation, avoids the situation of missing turning or uneven turning, improves the overall efficiency of the grass turning and drying, and optimizes the turning and drying effect.

[0051] Further, the deep rod 5 is arranged at the end of the grass turning part 402 away from the elastic part 401, and the deep rod 5 and the grass turning part 402 have a first included angle therebetween.

[0052] In this embodiment, the deep rod 5 is made of a stainless steel round rod, and is fixedly arranged at the end of the grass turning part 402 away from the elastic part 401 through welding. The deep rod 5 and the grass turning part 402 form a certain included angle, and the deep rod 5 can be inserted into the deep part of the grass pile to assist the grass turning part 402 to turn when the knife shaft rotates at a high speed.

[0053] The advantage is that the arrangement of the deep rod 5 further enhances the turning ability of the knife shaft on the grass, especially for the thicker and more compact grass pile. The deep rod 5 with a specific included angle can be easily inserted to turn up the bottom layer of grass, and cooperates with the grass turning part 402 to make the grass turning and drying more thorough, improve the uniformity of the drying, and reduce the drying time.

[0054] Further, the connecting rod 6 is arranged, and the two ends of the connecting rod 6 are connected with the two elastic parts 401 respectively. The connecting rod 6 has a clamping part 601, and the clamping part 601 abuts against the side of the mounting plate 3 away from the elastic part 401.

[0055] In this embodiment, the two ends of the connecting rod 6 are tightly clamped with the two adjacent elastic parts 401 through a specially made U-shaped clamping groove. The middle part of the connecting rod 6 is punched downward to form the clamping part 601. When the connecting rod 6 is clamped on the elastic part 401, the clamping part 601 tightly abuts against the side of the mounting plate 3 away from the elastic part 401, thereby achieving the transverse reinforcement of the elastic grass pushing part 4.

[0056] The advantage is that the reliable transverse connection and support are provided for the elastic grass pushing part 4, the stability of the elastic grass pushing part 4 during high-speed rotation is enhanced, displacement or deformation of the elastic grass pushing part 4 due to centrifugal force and other factors is prevented, the long-term stable operation of the knife shaft is ensured, and the maintenance frequency is reduced.

[0057] Further, the mounting plate 3 has a positioning hole, and the fastening bolt 7 is arranged and is threadedly connected with the positioning hole, and is used to fix the clamping part 601 on the mounting plate 3.

[0058] In the embodiment, the mounting plate 3 is drilled at the position close to the clamping portion 601 of the connecting rod 6 to form a positioning hole, the fastening bolt 7 is selected as a high-strength bolt, and the bolt is screwed with the threaded hole on the clamping portion 601 after passing through the positioning hole, so that the clamping portion 601 is firmly fixed on the mounting plate 3.

[0059] The fastening bolt 7 cooperates with the positioning hole to provide reliable guarantee for the fixation of the connecting rod 6, so that the assembly of the cutter shaft is more standardized and stable, and the overall reliability is improved.

[0060] Further, the clamping plate 8 is further included, the clamping plate 8 penetrates the pair of elastic portions 401, and the clamping plate 8 is threadedly connected with the fastening bolt 7.

[0061] In the embodiment, the clamping plate 8 is stamped and formed by a steel plate, and the shape is a long strip, the clamping plate 8 penetrates the middle of the pair of elastic portions 401, and the two ends are threadedly connected with the fastening bolt 7 through the round holes, so that the elastic portions 401 are further clamped and fixed.

[0062] The clamping plate 8 further strengthens the fixation effect of the elastic grass moving member 4, especially for the pair of elastic portions 401 that bear large centrifugal force, the double fixation mode makes it more stable, reduces the risk of loosening and falling of the elastic grass moving member 4 in the process of high-speed operation of the cutter shaft, and guarantees the safe operation and continuous operation ability of the equipment.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and are not limited, although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the utility model, and all should be included in the scope of the claims of the utility model.
