[0001] This utility model relates to the field of rotary tillage equipment technology, and in particular to a high-strength rotary tillage composite blade assembly. Background Technology

[0002] Rotary tillers, as an important type of agricultural machinery, are widely used in farmland tillage operations. Their core working component, the rotary tiller blade assembly, is directly responsible for cutting and breaking up the soil and mixing stubble, weeds, and other debris into the soil.

[0003] When operating in fields with abundant straw and weeds, existing rotary tiller blade sets are prone to having flexible grass stems easily entangled in the blade shaft, blade holder, and other structural components. As the entangled material accumulates, it increases power consumption, causes implement overload, and may even force the operator to frequently stop the machine for manual clearing, thus reducing operational efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength rotary tillage composite blade set, which solves the problems of poor anti-entanglement effect and impact on the continuity of operation of existing rotary tillage composite blade sets.

Each working component includes a blade holder, a mounting plate, rotary tillage blades, a connecting component, and an anti-tangling plate. The blade holder is fixedly connected to the blade shaft and mounted on it. The mounting plate is fixedly connected to the blade shaft and also to the blade holder, and is located on one side of the blade holder. The connecting component is mounted on the mounting plate. The rotary tillage blades are connected to the blade holder via the connecting component. The anti-tangling plate is fixedly connected to the mounting plate and mounted on it.

[0006] The mounting plate has a mounting portion extending in all directions, and a first mounting groove is provided on the mounting portion. The first mounting groove cooperates with the anti-tangle plate, and the anti-tangle plate is installed at the first mounting groove.

[0007] The anti-tangle plate has an extension that extends axially along the cutter shaft, and the end of the extension extends axially beyond the corresponding end face of the cutter shaft.

[0008] The anti-wrap plate also has several toothed protrusions, which are disposed on one side of the anti-wrap plate and are evenly distributed on the anti-wrap plate.

[0009] The working component further includes a reinforcing ring, which is annular and fixedly connected to the extension.

[0010] The connecting assembly includes a bolt and a nut. The rotary tiller has a through hole that passes through the rotary tiller. The bolt passes through the blade holder, the through hole, and the mounting plate. The nut is threaded to the bolt and is fitted onto the bolt.

[0011] The mounting plate also has a positioning groove that penetrates the mounting plate; the tool holder has a positioning protrusion that is located on the side of the tool holder near the positioning groove and engages with the positioning groove.

[0012] This utility model discloses a high-strength rotary tillage composite blade assembly. During operation, the agricultural equipment provides power to drive the blade shaft to rotate. The L-shaped horizontal working section of the rotary tillage blade first cuts into the soil, achieving a composite tillage effect of cutting, lifting, and crushing.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] First embodiment: Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of a high-strength rotary tillage composite blade assembly. Figure 2 This is a structural diagram of the first mounting slot. Figure 3 This is a schematic diagram of the positioning protrusion.

[0021] This utility model provides a high-strength rotary tillage composite blade assembly, including a blade shaft 101 and multiple working components 102. Each working component 102 includes a blade holder 103, a mounting plate 104, rotary tillage blades 105, a connecting component 106, and an anti-tangling plate 107. The working component 102 also includes a reinforcing ring 111. The connecting component 106 includes bolts 112 and nuts 113. The mounting plate 104 also has a positioning groove 114. The anti-tangling plate 107 prevents weeds from tangling on the blade shaft 101 and the blade holder 103 during operation, improving the continuity of operation and reducing downtime. It is understood that the aforementioned solution can be used to prevent weeds from tangling on the blade shaft 101.

[0022] In this specific embodiment, the blade holder 103 is fixedly connected to the blade shaft 101 and is disposed on the blade shaft 101. The mounting plate 104 is fixedly connected to the blade shaft 101 and to the blade holder 103, and is located on one side of the blade holder 103. The connecting assembly 106 is disposed on the mounting plate 104. The rotary tiller blade 105 is connected to the blade holder 103 through the connecting assembly 106. The anti-tangling plate 107 is fixedly connected to the mounting plate 104 and is disposed on the mounting plate 104. The blade shaft 101 has a hexagonal cylindrical structure and can be installed between two end plates of the agricultural equipment (not shown in the figure) frame, and is driven by the power device of the agricultural equipment to achieve rotational operation. Multiple working components 102 are arranged along the axis of the blade shaft 101. The working assembly 102 is provided with three blade holders 103 and three rotary tillers 105. The blade holders 103 are C-shaped, and a slot 117 is formed between the blade holders 103 and the mounting plate 104. The root of the rotary tiller 105 can be inserted into the slot 117. The connecting assembly 106 is used to fix the rotary tiller 105 in the slot 117. Three anti-tangling plates 107 are provided in total, and one anti-tangling plate 107 is simultaneously connected to three mounting plates 104 by bolts. The end of the rotary tiller 105 is L-shaped, and its structure consists of an integrally formed vertical section and a horizontal working section. The vertical section serves as the connecting root, and the horizontal working section serves as the main tillage component. Its cutting edge is opened on the side facing the rotation direction for cutting into and breaking the soil during operation.

[0023] In use, the mounting plate 104 is welded to the blade holder 103 to form a slot 117 between the blade holder 103 and the blade holder 103. Then, the root of the rotary tiller 105 is inserted into the slot 117, and the root of the rotary tiller 105 is fixed in the slot 117 by the connecting assembly 106. Then, the anti-tangling plate 107 is fixedly connected to the mounting plate 104. Then, the assembled blade shaft 101 assembly is installed onto the frame of the agricultural equipment through the connecting structures at both ends, and the blade shaft... 101 is connected to the power output mechanism; during operation, the agricultural equipment provides power to drive the blade shaft 101 to rotate. The L-shaped horizontal working section of the rotary tiller 105 first cuts into the soil, achieving a composite tillage effect of cutting, lifting, and crushing. At the same time, the anti-tangling plate 107 moves with the rotary tiller 105. Its surface can effectively block, cut, and guide weeds and straw, preventing them from getting tangled on the blade shaft 101 or the blade holder 103, thereby ensuring the continuity and stability of the tillage process, reducing the frequency of downtime for cleaning, and improving operating efficiency.

[0024] The mounting plate 104 has a mounting portion 108 extending in all directions. The mounting portion 108 is provided with a first mounting groove 116. The first mounting groove 116 cooperates with the anti-wrap plate 107, and the anti-wrap plate 107 is installed in the first mounting groove 116. The first mounting groove 116 is a recessed structure adapted to the thickness of the anti-wrap plate 107. Its outline is consistent with the edge shape of the anti-wrap plate 107, so that the anti-wrap plate 107 can be embedded and attached to the groove. By increasing the contact area, the stability of the anti-wrap plate 107 is enhanced.

[0025] Secondly, the anti-tangling plate 107 has an extension 109 that extends axially along the cutter shaft 101 and the end of the extension 109 extends axially beyond the corresponding end face of the cutter shaft 101. When the cutter shaft 101 rotates, the extension 109 can block weeds and straws that attempt to flow to the end of the cutter shaft 101, preventing weeds from tangling on the end components of the cutter shaft 101.

[0026] Meanwhile, the anti-tangling plate 107 also has a number of toothed protrusions 110, which are disposed on one side of the anti-tangling plate 107 and are evenly distributed on the anti-tangling plate 107. The toothed protrusions 110 and the plate body of the anti-tangling plate 107 are integrally formed by stamping, which ensures the connection strength. The evenly distributed toothed protrusions 110 divide large sections of weeds into multiple small sections, changing the physical form of the tangled material, making it easier for it to be broken up or thrown away from the working area by the subsequent rotary tiller blades 105, thereby improving the anti-tangling plate 107's ability to deal with complex and dense weeds.

[0027] In addition, the reinforcing ring 111 is annular and is fixedly connected to the extension 109; the reinforcing ring 111 is connected to the outer end face of the extension 109, and the reinforcing ring 111 is fixedly connected to the extension 109 of each of the anti-winding plates 107 by means of bolts 112, thereby connecting multiple independent anti-winding plates 107 into an integral frame, which enhances the overall rigidity and stability of the anti-winding plates 107.

[0028] Then, the rotary tiller 105 has a through hole that passes through the rotary tiller 105, and the bolt 112 passes through the blade holder 103, the through hole, and the mounting plate 104; the nut 113 is threadedly connected to the bolt 112 and is fitted onto the bolt 112; the mounting plate 104 and the blade holder 103 are provided with through holes corresponding to the bolt 112. When installing the rotary tiller 105, the root of the rotary tiller 105 is inserted into the slot 117, and then the bolt 112 is passed through the through holes on the mounting plate 104, the rotary tiller 105, and the blade holder 103 in sequence. Finally, the nut 113 is threadedly connected to the bolt 112 and tightened, thereby completing the installation of the rotary tiller 105; when the rotary tiller 105 is worn and needs to be replaced, simply loosen the nut 113 and remove the bolt 112 to pull the old blade out of the slot 117, making maintenance simple and efficient.

[0029] Finally, the mounting plate 104 also has a positioning groove 114 that penetrates through the mounting plate 104; the tool holder 103 has a positioning protrusion 115 that is disposed on the side of the tool holder 103 near the positioning groove 114 and engages with the positioning groove 114; the shape of the positioning protrusion 115 is adapted to the shape of the positioning groove 114, and during installation, the positioning protrusion 115 can be embedded in the positioning groove 114 to achieve circumferential positioning and radial limiting between the tool holder 103 and the mounting plate 104; at the same time, it ensures that the tool holder 103 and the mounting plate 104 are in a positioned state before welding and fixing, preventing misalignment during welding, and further enhancing the overall structural reliability and service life of the tool assembly.

[0030] When using the high-strength rotary tillage composite blade assembly of this embodiment, in fields with dense straw, the anti-tangling plate 107 prevents weeds from wrapping around the blade shaft 101, and the extension 109 protects the end area of ​​the blade shaft 101; while the toothed protrusion 110 actively cuts long-fiber weeds; the reinforcing ring 111 connects each of the anti-tangling plates 107 into a whole, further enhancing the stability of the device under uneven loads, so that key components such as the blade shaft 101 and the blade holder 103 are kept clean during operation, preventing overload shutdown due to tangling; When the rotary tiller blade 105 is worn and needs to be replaced, maintenance personnel only need to use a wrench to loosen the nut 113 and remove the bolt 112 to pull the worn rotary tiller blade 105 out of the slot 117 and replace it with a new blade. The whole process does not require disassembling the blade shaft 101 or other parts and can be completed quickly in the field, reducing equipment maintenance time and labor costs. In summary, this utility model solves the pain points of traditional rotary tiller blade 105 sets such as easy tangling, insufficient strength, and inconvenient maintenance through innovative structural design, and achieves the goals of high reliability, high operating efficiency and low maintenance costs.

[0031] Second embodiment: Based on the first embodiment, please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of the second mounting groove in the second embodiment. The mounting part 108 in this embodiment also has a second mounting groove 201.

[0032] In this specific embodiment, the working component 102 further includes a grass shredder 202, which is fixedly connected to the anti-tangling plate 107 and cooperates with the second mounting groove 201; the grass shredder 202 is V-shaped, and its cutting edge is opened on the side facing the rotation direction.

[0033] The mounting plate 104 is provided with three second mounting slots 201. When the grass shredder 202 needs to be installed, the anti-tangling plate 107 is first removed, and then the mounting base of the grass shredder 202 is aligned and placed into the second mounting slot 201. Then, the grass shredder 202 is directly fixed to the mounting part 108 using bolt assembly. During operation, the grass shredder 202 rotates together with the blade shaft 101. The grass shredder 202 can perform secondary cutting and refining of the soil clods and residual short roots that have been initially broken by the rotary tiller 105, further improving the soil breaking effect and surface flatness. It is suitable for farming scenarios with higher requirements for soil breaking rate and straw return quality.

[0034] In this embodiment, the cooperation between the second mounting slot 201 and the first mounting slot 116 enables modular replacement of two functional components: the anti-tangling plate 107 and the grass shredder 202. Users can flexibly choose to install the anti-tangling plate 107 (focusing on anti-tangling) or the grass shredder 202 (focusing on fine soil shredding) according to actual field conditions (such as the amount of weeds, the amount of straw returned to the field, and the requirements for soil shredding effect), thereby greatly enhancing the functional adaptability and comprehensive agronomic effect of the blade set.

[0035] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
