Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a three- or four-bladed staggered high-efficiency paddy field wheel. Background Technology

[0002] Paddy field tillage is a crucial step in rice cultivation, and its quality directly affects transplanting results and crop yield. The paddy field wheel, also known as the agitator shaft, is a core working component of agricultural machinery such as paddy field agitators and pulpers. Its main function is to rotary tillage, break up, and level the paddy field soil, while simultaneously chopping up rice stubble, straw, and other residues and burying them in the mud, thus returning straw to the field.

[0003] However, existing paddy field reels generally suffer from insufficient uniformity in soil breaking: most paddy field reels use a symmetrically distributed design for their functional blades (such as breaking blades and stirring blades). While this design facilitates processing and assembly, during actual operation, the symmetrically distributed blades create fixed "breaking blind spots" on their movement trajectory—meaning that some soil areas are never touched or broken by the blades. This results in "missed tillage" areas in the paddy field where soil particles are too large and compacted. These areas not only affect the smooth entry of seedlings into the soil and the spread of roots during transplanting, but may also cause uneven distribution of water and nutrients in the field later, adversely affecting the early growth of rice. Utility Model Content

[0004] The purpose of this invention is to provide a three- or four-bladed staggered high-efficiency paddy field wheel, which solves the problem that most paddy field wheels use a symmetrically distributed design for their functional blades (such as crushing blades and stirring blades). Although this design is convenient for processing and assembly, when the wheel is actually rotating, the symmetrically distributed blades will form a fixed "crushing blind zone" on its movement trajectory. That is, some soil areas cannot be contacted and crushed by the blades, resulting in the problem of "missed tillage" areas in the paddy field where the soil particles are too large and the soil is compacted and not dispersed.

[0005] To achieve the above objectives, this utility model provides a three- or four-bladed staggered high-efficiency paddy field wheel, including a cutter shaft and a rotary tillage device. The rotary tillage device includes bent and reinforced blades, ram's horn blades, a toothed stabilizing disc, and a mounting assembly. The toothed stabilizing disc is fixedly mounted on the cutter shaft, the bent and reinforced blades are fixedly mounted on the toothed stabilizing disc, and the ram's horn blades are mounted on the cutter shaft via the mounting assembly. The toothed stabilizing disc is also provided with a first slot and a second slot.

[0006] The mounting assembly includes a mounting sleeve and a fastening bolt. The mounting sleeve is fixedly mounted on the cutter shaft. The horn-shaped blade is inserted into the mounting sleeve and fixed inside the mounting sleeve by the fastening bolt.

[0007] The bent and reinforced blade is also provided with a soil-breaking reinforcement block, which is fixedly installed on the outside of the bent and reinforced blade.

[0008] The toothed stabilizer disk is also provided with an anti-entanglement component, which includes an anti-entanglement crawling plate and a connecting member. The anti-entanglement crawling plate is installed on the toothed stabilizer disk through the connecting member.

[0009] The connecting component includes a first insert and a second insert, which are fixedly installed on the anti-entanglement crawling plate and respectively inserted into the first slot and the second slot.

[0010] This utility model discloses a three- or four-bladed staggered high-efficiency paddy field wheel. In use, the cutter shaft is driven to rotate via an external tractor power take-off shaft. The cutter shaft, through a toothed stabilizing disc, drives the bent and reinforced blades to rotate. The rotation of the bent and reinforced blades on both sides breaks up the soil in the field. Simultaneously, the rotation of the cutter shaft drives the horn-shaped blades to rotate, penetrating deep into the soil and bringing it out for cutting. With the combined action of the bent and reinforced blades, the paddy field soil is transformed into mud. The circumferential staggered distribution of the bent and reinforced blades on both sides of the cutter shaft, along with the combined action of the horn-shaped blades, ensures that the soil in the field is fully in contact with the blades and blades, allowing for uniform soil breaking up and preventing missed tillage.

Detailed Implementation

[0017] 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.

[0018] The embodiment of this application is as follows: Please see Figure 1-4 , Figure 1 This is a schematic diagram of the overall structure of a three- or four-bladed staggered high-efficiency paddy field wheel according to this utility model. Figure 2 This is a schematic diagram showing the connection between the toothed stabilizing disc and the anti-entanglement crawling plate of this utility model. Figure 3 This is a schematic diagram of the structure of the first and second insert blocks of this utility model. Figure 4 This is a schematic diagram of the toothed stabilizer disc of this utility model.

[0019] This utility model provides a three- or four-bladed staggered high-efficiency paddy field wheel: it includes a blade shaft 101 and a rotary tillage device. The rotary tillage device includes a bent and reinforced blade 102, a horn-shaped blade 103, a toothed stabilizing disc 104, and an installation component. The installation component includes an installation sleeve 107 and a fastening bolt 108. The bent and reinforced blade 102 is also provided with a soil-breaking reinforcing block 109. The toothed stabilizing disc 104 is also provided with an anti-entanglement component. The anti-entanglement component includes an anti-entanglement crawling plate 110 and a connecting component. The connecting component includes a first insert block 111 and a second insert block 112. The aforementioned solution solves the problem that most paddy field wheels use a symmetrically distributed design for their functional blades (such as crushing blades and stirring blades). Although this design is convenient for processing and assembly, when the wheel is actually rotating, the symmetrically distributed blades will form a fixed "crushing blind zone" on their movement trajectory. That is, some soil areas cannot be contacted and crushed by the blades, resulting in "missed tillage" areas in the paddy field where the soil particles are too large and compacted.

[0020] In this embodiment, the circumferentially staggered distribution of the bending reinforcement blades 102 on both sides of the blade shaft 101, along with the cooperation of the ram's horn blades 103, ensures that the soil in the field is in full contact with the blades and leaves, allowing the soil to be uniformly broken up and preventing missed tillage.

[0021] The toothed stabilizing disc 104 is fixedly mounted on the cutter shaft 101, the bent reinforcing blade 102 is fixedly mounted on the toothed stabilizing disc 104, and the horn-shaped blade 103 is mounted on the cutter shaft 101 via the mounting assembly. The toothed stabilizing disc 104 is also provided with a first slot 105 and a second slot 106. The cutter shaft 101 has a hexagonal prism structure and is hollow inside, reducing its weight. There are three sets of toothed stabilizing discs 104, evenly distributed along the axis of the cutter shaft 101. The outer periphery of the toothed stabilizing disc 104 has a toothed structure, which reduces soil adhesion. There are six sets of bent reinforcing blades 102, with three sets on each side of the cutter shaft 101 between the toothed stabilizing discs 104. The bent reinforcing blades 102 on both sides are circumferentially staggered. The ram's horn blades 103 have a ram's horn-shaped structure and are detached and installed on the cutter shaft 101 via the mounting assembly. Each edge of the cutter shaft 101 is provided with a set of ram's horn blades 103, which are also distributed left and right and staggered with the bent reinforcing blades 102. The cutter shaft 101 drives the toothed stabilizing disc 104 to rotate, so that the bent reinforcing blades 102, in cooperation with the ram's horn blades 103, uniformly break up the field soil. At the same time, the circumferential staggered distribution of the bent reinforcing blades 102 on both sides of the cutter shaft 101, as well as the staggered distribution of the ram's horn blades 103 and the bent reinforcing blades 102, prevents missed tillage.

[0022] Secondly, the mounting sleeve 107 is fixedly mounted on the cutter shaft 101; the horn blade 103 is inserted into the mounting sleeve 107 and fixed inside the mounting sleeve 107 by the fastening bolt 108. The mounting sleeve 107 is welded to the cutter shaft 101. By inserting the horn blade 103 into the mounting sleeve 107 and tightening the fastening bolt 108, the horn blade 103 can be fixed, and it is also easy to disassemble and replace.

[0023] Furthermore, the soil-breaking reinforcement block 109 is fixedly installed on the outside of the bending reinforcement blade 102. The soil-breaking reinforcement block 109 is welded to the outside of the bending reinforcement blade 102. By setting the soil-breaking reinforcement block 109, the soil-breaking ability of the bending reinforcement blade 102 can be improved.

[0024] Furthermore, the anti-tangling crawling plate 110 is mounted on the toothed stabilizing plate 104 via the connecting member. The anti-tangling crawling plate 110 consists of four rings, which are welded to the toothed stabilizing plate 104 at the left end. The connecting member facilitates the mounting of the anti-tangling crawling plate 110. The anti-tangling crawling plate 110 helps prevent weeds from tangling in the field.

[0025] Finally, the first insert 111 and the second insert 112 are fixedly installed on the anti-tangling crawling plate 110 and respectively inserted into the first slot 105 and the second slot 106. The first insert 111 and the second insert 112 are both square structures. The insertion of the first insert 111 and the second insert 112 into the first slot 105 and the second slot 106 facilitates the mounting of the anti-tangling crawling plate 110 and provides greater torque to the anti-tangling crawling plate 110.

[0026] In this embodiment, during use, the cutter shaft 101 is driven to rotate by the power take-off shaft of an external tractor. The cutter shaft 101 drives the bent and reinforced blades 102 to rotate via the toothed stabilizing disc 104. The rotation of the bent and reinforced blades 102 on both sides breaks up the soil in the field. At the same time, the rotation of the cutter shaft 101 drives the ram's horn blades 103 to rotate. The ram's horn blades 103 penetrate into the soil, bringing out the soil and cutting it. With the cooperation of the bent and reinforced blades 102, the paddy field soil is turned into mud. Thus, through the circumferential staggered distribution of the bent and reinforced blades 102 on both sides of the cutter shaft 101, and with the cooperation of the ram's horn blades 103, the soil in the field is fully in contact with the blades and blades, so that the soil can be broken up evenly and the missed tillage is avoided.

[0027] 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 all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application still fall within the scope of this application.
