Description

Technical Field

[0001] This utility model relates to the technical field of slurry-throwing equipment for paddy field operations, and in particular to a new type of slurry-throwing blade assembly suitable for paddy field operations. Background Technology

[0002] The existing paddy field pulverizers mainly consist of a cutter shaft and multiple pulverizing blades assembled on the cutter shaft at certain intervals. In actual operation, straw often gets tangled on the blades, and large chunks of mud are difficult to crush. This increases the resistance encountered by the blades during pulverizing, and the straw tangling further exacerbates the problem of mud adhesion, greatly reducing the pulverizing effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a new type of slurry-throwing blade assembly suitable for paddy field operations, which improves the effect of the slurry-throwing blade assembly in cutting straw and crushing mud, and creates a loose and uniform soil environment for the growth of rice roots.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A novel slurry-throwing blade assembly suitable for paddy field operations includes a paddy field wheel, slurry-throwing blades, a disc blade, and a blade shaft.

[0006] The paddy field wheel, the slurry-throwing knife, and the disc knife are all mounted on the cutter shaft. There are two paddy field wheels, located at the left and right ends of the cutter shaft, respectively.

[0007] The disc cutter has at least five serrated large cutting edges arranged circumferentially. The serrated large cutting edges are inclined sharp teeth. One tooth surface of the serrated large cutting edge is a short plane, and the other tooth surface is a long arc surface. Each long arc surface is provided with multiple toothed small cutting edges arranged in a straight line.

[0008] Furthermore, the small toothed cutting edge is an inclined pointed tooth, and the inclination direction of the small toothed cutting edge is consistent with the inclination direction of the large serrated cutting edge.

[0009] Furthermore, the root of the serrated large cutting edge of one of the disc cutters corresponds in direction to the tip of the serrated large cutting edge of the adjacent disc cutter.

[0010] Furthermore, each of the slurry cutting blades has at least three slurry cutting blades evenly distributed around its circumference. The frontal projection of each slurry cutting blade is an L-shape with rounded corners. The slurry cutting blades are bent toward the left or right end of the cutting shaft. Each slurry cutting blade has multiple triangular toothed blades arranged one by one on its slurry-facing surface.

[0011] Furthermore, the slurry blade includes a curved right-angled trapezoidal blade and a mounting shank integrally connected to the acute angle of the right-angled trapezoidal blade, the mounting shank being fixed to the blade shaft.

[0012] Furthermore, a flow guide groove is provided on the inner side of the slurry blade along its length.

[0013] Furthermore, a slurry-blasting blade that bends to the left end of the cutter shaft, two disc cutters, and another slurry-blasting blade that bends to the right end of the cutter shaft constitute a slurry-blasting and crushing blade assembly, and at least one of the slurry-blasting and crushing blade assemblies is mounted on each cutter shaft.

[0014] Furthermore, the installation sequence of the slurry pulverizing blade assembly is as follows: one slurry pulverizing blade bent to the left end of the cutter shaft, two disc cutters, and another slurry pulverizing blade bent to the right end of the cutter shaft.

[0015] Furthermore, the installation sequence of the slurry pulverizing blade assembly is as follows: one disc blade, one slurry pulverizing blade bent to the left end of the blade shaft, another disc blade, and another slurry pulverizing blade bent to the right end of the blade shaft.

[0028] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Please refer to Figures 1 to 5 The embodiments provided by this utility model are as follows:

[0030] A novel slurry-throwing blade assembly suitable for paddy field operations includes a paddy field wheel 1, a slurry-throwing blade 2, a disc blade 3, and a blade shaft 4. The paddy field wheel 1, the slurry-throwing blade 2, and the disc blade 3 are all mounted on the blade shaft 4. There are two paddy field wheels 1, located at the left and right ends of the blade shaft 4, respectively. The slurry-throwing blade 2 and the disc blade 3 are located between the two paddy field wheels 1. The combination of the paddy field wheel 1, the slurry-throwing blade 2, and the disc blade 3 improves the effect of crushing straw and mud, and enhances the quality of slurry-throwing operations.

[0031] The disc cutter 3 has at least five serrated large cutting edges 31 arranged circumferentially, such as... Figure 1 and Figure 2 As shown, the serrated large cutting edge 31 consists of inclined sharp teeth. During operation, the sharp teeth are positioned to face the slurry, enabling them to cut straw and break up the mud. Specifically, the number of serrated large cutting edges 31 can be five, six, seven, eight, nine, ten, eleven, or twelve.

[0032] Specifically, one tooth surface of the serrated large cutting edge 31 is a short plane 311, and the other tooth surface is a long arc surface 312. Because the serrated large cutting edge 31 is inclined, the center of each long arc surface 312 does not coincide with the center of the disc cutter 3. Furthermore, from the intersection of the short plane 311 and the long arc surface 312 to the root of the long arc surface 312, the distance between the point on the long arc surface 312 and the center of the disc cutter 3 gradually decreases. Each long arc surface 312 has multiple small toothed cutting edges 32 arranged in a straight line, such as... Figure 1 and Figure 2As shown. On each long arc surface 312, multiple toothed small cutting edges 32 are arranged one after another along the long arc surface 312. This can further improve the speed and ability of the disc cutter 3 to cut straw, and can also break the mud into smaller pieces. Moreover, the mud is less likely to stick to the toothed surfaces of the disc cutter 3, thereby reducing the resistance during the movement of the pulping machine.

[0033] Specifically, in each of the serrated large cutting edges 31, the height of the short plane 311 is less than or equal to half the length of the long arc surface 312, which gives it a stronger effect in cutting straw and breaking up mud.

[0034] In summary, the slurry-throwing blade 2 crushes, rolls up, and throws the mud and straw, while the disc blade 3 directly cuts and crushes the straw and mud. Therefore, this new type of slurry-throwing blade assembly combines the paddy field wheel 1, the slurry-throwing blade 2, and the disc blade 3 to improve the effect of crushing straw and mud from multiple dimensions. It also overcomes the problem of adhesion and clogging of traditional blades, greatly improves the quality of paddy field preparation operations, and creates a loose and uniform soil environment for rice root growth.

[0035] Furthermore, the small toothed cutting edge 32 is an inclined pointed tooth, and the inclination direction of the small toothed cutting edge 32 is consistent with the inclination direction of the large serrated cutting edge 31. That is, the small toothed cutting edge 32 has the same working direction for cutting straw and breaking up mud as the large serrated cutting edge 31, further improving the effectiveness and efficiency of the disc cutter 3 in cutting straw and breaking up mud. Regarding the specific inclination angle of the small toothed cutting edge 32, on each long arc surface 312, multiple small toothed cutting edges 32 continuously change their inclination angle along the long arc surface 312 to ensure that the included angle between each small toothed cutting edge 32 and the long arc surface 312 remains consistent, that is, to ensure that each small toothed cutting edge 32 has a basically consistent cutting angle and cutting performance.

[0036] Furthermore, the central disc surface of the disc cutter 3 adopts a hollow structure, which can reduce the weight of the disc cutter 3 and further prevent mud lumps from adhering to the disc cutter 3.

[0037] Furthermore, the cross-sectional shape of the cutter shaft 4 perpendicular to the axis is polygonal, which can prevent slippage during the operation of the paddy field wheel 1, the slurry-throwing cutter 2, and the disc cutter 3.

[0038] Furthermore, the root of the tooth of the serrated large cutting edge 31 of one of the disc cutters 3 corresponds to the direction of the tooth tip of the adjacent serrated large cutting edge 31 of the disc cutter 3. With the cooperation of two adjacent disc cutters 3, it can be ensured that there are toothed small cutting edges 32 within a 360-degree range to cut the straw and crush the mud, ensuring the mud-throwing operation effect within the entire circumference.

[0039] Furthermore, such as Figure 4 and Figure 5 As shown, each of the slurry-throwing blades 2 has at least three slurry-throwing blades 21 evenly distributed around its circumference. The frontal projection of each slurry-throwing blade 21 is L-shaped with rounded corners. The slurry-throwing blade 21 bends towards the left or right end of the blade shaft 4. Each slurry-facing surface of the slurry-throwing blade 21 has multiple triangular toothed blades 211 arranged in a row. By bending the L-shaped slurry-throwing blades 21, the mud and straw are broken up, rolled up, and thrown out. The multiple triangular toothed blades 211 on the mud-facing surface of the slurry-throwing blades 21 improve the effect of cutting straw and crushing mud, and prevent straw entanglement and mud adhesion.

[0040] Specifically, the slurry-spraying blade 21 includes a curved right-angled trapezoidal blade 212 and a mounting shank 213 integrally connected to the acute angle of the right-angled trapezoidal blade 212. The mounting shank shank 213 is fixed on the blade shaft 4. The right-angled trapezoidal blade 212 includes a short base, a straight side, a long base, and a bevel. The slurry-facing surface of the slurry-spraying blade 21 is the short base plate, the bevel, and the rounded corner between the straight side and the short base of the right-angled trapezoidal blade 212.

[0041] Furthermore, such as Figure 4 and Figure 5 As shown, a flow guide groove 214 is provided on the inner side of the slurry blade 21 along its length direction. When the slurry blade 21 is thrown, excess water flows back to the furrow through the flow guide groove 214, reducing the operating resistance.

[0042] Furthermore, a slurry-throwing blade 2 bent towards the left end of the cutter shaft 4, two disc cutters 3, and another slurry-throwing blade 2 bent towards the right end of the cutter shaft 4 constitute a slurry-throwing and crushing blade assembly 5. At least one slurry-throwing and crushing blade assembly 5 is mounted on each cutter shaft 4, and at least one slurry-throwing and crushing blade assembly 5 is required depending on the length of the slurry-throwing machine. If there are multiple slurry-throwing and crushing blade assemblies 5, they are arranged in a line to increase the range of a single slurry-throwing operation.

[0043] Specifically, one embodiment of the slurry pulverizing blade assembly 5 is as follows: the installation sequence of the slurry pulverizing blade assembly 5 is: one slurry pulverizing blade 2 bent towards the left end of the blade shaft 4, two disc blades 3, and another slurry pulverizing blade 2 bent towards the right end of the blade shaft 4.

[0044] Specifically, another embodiment of the slurry pulverizing blade assembly 5 is as follows: the installation sequence of the slurry pulverizing blade assembly 5 is: one disc blade 3, one slurry pulverizing blade 2 bent to the left end of the blade shaft 4, another disc blade 3, and another slurry pulverizing blade 2 bent to the right end of the blade shaft 4.

[0045] Furthermore, such as Figure 1 and Figure 3 As shown, the paddy field wheel 1 adopts a spoke-type hollow structure, including a spoke wheel 11, wheel pieces 12 evenly distributed on the spoke wheel 11, and reinforcing plates 13 located on both sides of the wheel pieces 12, which have the functions of supporting and preventing sinking and assisting in breaking up soil.

[0046] The aforementioned new type of slurry-throwing blade assembly, suitable for paddy field operations, is installed at the rear of the slurry-throwing machine. It is supported by the paddy field wheel 1 to prevent sinking and assist in breaking up the soil. The slurry-throwing blade 2 crushes, rolls up, and throws out the straw and mud. The disc blade 3 can cut the straw and crush the mud throughout the entire stroke range of the slurry-throwing machine, which can improve the quality of paddy field preparation operations and create a loose and uniform soil environment for rice root growth.

[0047] In summary, the novel slurry-throwing blade assembly for paddy field operations provided by this utility model has the following advantages:

[0048] 1. The disc cutter 3 has a circumferentially arranged staggered sawtooth-shaped large cutting edge 31 and tooth-shaped small cutting edge 32 with a gradient design of sawtooth depth, which can cut sand and gravel of different particle sizes and high toughness straw. It forms a multi-dimensional complementary cutting network with the slurry-throwing cutter 2 and prevents mud adhesion.

[0049] 2. The slurry blade 21 adopts a composite design of hyperboloid wedge-shaped blade body and triangular toothed blade 211. The blade surface is provided with a flow guide groove 214, which can return excess water during slurrying to the furrow through the flow guide groove, reduce working resistance, and prevent mud adhesion.

[0050] 3. The outer paddy field wheel 1 adopts a spoke-shaped hollow structure, which has the functions of supporting and preventing sinking, assisting in soil breaking and preventing mud adhesion.

[0051] 4. This device, through the synergistic action of three-stage cutters, directs the mud layer to form longitudinally spaced mud-throwing and soil-breaking zones, overcoming the problem of adhesion and clogging of traditional cutters, improving the quality of paddy field preparation operations, and creating a loose and uniform soil environment for rice root growth.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
