Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposal, in particular to a kitchen garbage crushing device. Background Art

[0002] Patent publication number CN116239402A discloses a device for rapidly processing kitchen waste. The device comprises a housing and a crushing mechanism, which includes a fixed blade assembly, a rotating shaft, and a movable blade assembly. The fixed blade assembly is fixed to the inner wall of the housing, and the rotating shaft is located in the middle of the bottom of the housing. The movable blade assembly is rotatably mounted on the rotating shaft and includes several movable blades. The movable blade assembly and the fixed blade assembly move relative to each other to grind the kitchen waste. A drawback of this prior art is that the movable blade assembly and the fixed blade assembly have fewer cutting edges, resulting in low efficiency in grinding the kitchen waste.

[0003] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0004] In order to solve the problems of the prior art, the utility model provides a kitchen waste crushing device, the movable blade and the fixed blade of which have more cutting edges, thereby achieving the effect of quickly cutting and crushing the kitchen waste.

[0005] In order to achieve the above-mentioned purpose, the technical solution applied by the present utility model is as follows:

[0006] A kitchen waste shredding device includes a housing with a rotatable transmission shaft disposed therein; a fixed blade mechanism fixed within the housing, comprising multiple fixed blade assemblies, each comprising multiple fixed blades of varying heights, each provided with multiple fixed blade cutting edges; and a movable blade mechanism fixed to the transmission shaft, comprising multiple movable blades, each provided with multiple movable blade cutting edges of varying heights. The movable blade mechanism rotates forward and reverse relative to the fixed blade mechanism, with the movable blades corresponding to the fixed blades of the fixed blade assembly. This arrangement, by providing multiple fixed blade cutting edges and multiple movable blade cutting edges on the fixed blade mechanism and the movable blade mechanism, results in a large number of cutting edges, which, when combined with shearing action, allows for rapid cutting and shredding of kitchen waste.

[0007] According to the above solution, the fixed blade mechanism includes a fixed blade mounting base and multiple fixed blade assemblies spaced apart on the fixed blade mounting base. The fixed blade assemblies include an upper fixed blade, a middle fixed blade, and a lower fixed blade. The upper fixed blade has a fixed blade cutting edge 1, the middle fixed blade has a fixed blade cutting edge 2, and the lower fixed blade has a fixed blade cutting edge 3. This arrangement allows the upper fixed blade, the middle fixed blade, and the lower fixed blade, each of different heights, to cooperate to shred garbage at different locations within the housing.

[0008] According to the above solution, arc grooves are formed on the outer walls of the upper fixed blade and the middle fixed blade. In this way, when the movable blade mechanism rotates forward and reverse relative to the fixed blade mechanism, the arc grooves can block the garbage and then cut it.

[0009] According to the above solution, the lower fixed blade is formed with a groove, and the outer sides of the lower fixed blade are formed with wavy teeth. In this way, when the movable blade mechanism rotates forward and backward relative to the fixed blade mechanism, the wavy teeth and grooves block the garbage and then cut it.

[0010] According to the above solution, the movable blade mechanism includes a movable blade mounting base and two sets of movable blades mirror-imaged on the movable blade mounting base. The movable blades are formed with movable blade edge 1, movable blade edge 2, and movable blade edge 3. Moving blade edge 1 corresponds to fixed blade edge 1, moving blade edge 2 corresponds to the middle fixed blade, and moving blade edge 3 corresponds to fixed blade edge 3. This arrangement improves crushing efficiency by allowing multiple sets of movable blade edges to cooperate with fixed blade edges.

[0011] According to the above solution, the movable blade is formed with a first notch and a second notch. The first notch is provided corresponding to the upper fixed blade, and the second notch is provided corresponding to the middle fixed blade. This arrangement facilitates cross-cutting with the upper and middle fixed blades through the first notch and the second notch, thereby improving the crushing efficiency.

[0012] According to the above scheme, one side of the movable blades serves as a gathering surface, while the other side serves as a dispersing surface. The angle formed between the gathering surfaces of the two sets of movable blades is a pure angle a1, or the angle formed between the dispersing surfaces of the two sets of movable blades is a pure angle a2. When the dispersing surface of one set of movable blades and the corresponding fixed blades are in a cutting state, the gathering surface of the other set of movable blades drives the garbage and the fixed blades into a non-cutting state. This arrangement causes the garbage to be gathered inward at one end and dispersed outward at the other end, resulting in a moderately balanced force, which in turn generates the maximum shear force on the garbage, thereby improving shear force. This also ensures concentrated cutting force, low resistance, and low power consumption, eliminating the high resistance and power consumption associated with multiple blade sets.

[0013] According to the above solution, a stirring paddle is provided on the movable blade mounting seat, and the stirring paddle is located between the two sets of movable blades. In this way, the garbage in the housing can be stirred by the stirring paddle to improve the crushing efficiency.

[0014] According to the above scheme, the gap between the movable blade edge 1 and the fixed blade edge 1 is d, the gap between the movable blade edge 2 and the middle fixed blade is c, the gap between the movable blade edge 3 and the fixed blade edge 3 is b, the gap between the movable blade edge 3 and the bottom of the housing is e, and the gap between the fixed blade edge 3 and the bottom of the housing is a. The gaps a, b, c, d, and e are of different sizes. This arrangement can be set to shear objects of different sizes and thicknesses to improve the crushing efficiency.

[0015] According to the above solution, a sealing member is provided between the transmission shaft and the housing to prevent leakage.

[0016] Beneficial effects of the utility model:

[0017] The utility model is configured in this way, by arranging multiple fixed blade cutting edges and multiple movable blade cutting edges on the fixed blade mechanism and the movable blade mechanism, the utility model has multiple cutting edges, and under the coordinated shearing action, the effect of quickly cutting and crushing kitchen waste is achieved.

[0031] The technical solution of the present utility model is described below with reference to the accompanying drawings and embodiments.

[0032] Example 1:

[0033] like Figures 1 to 8 As shown, the kitchen waste shredder device of the present invention comprises a housing 1, within which a rotatable transmission shaft 4 is disposed; a fixed blade mechanism 6, fixed within the housing 1, comprising multiple fixed blade assemblies 67, each comprising multiple fixed blades of varying heights, each provided with multiple fixed blade edges; and a movable blade mechanism 5, fixed to the transmission shaft 4, comprising multiple movable blades 51, each provided with multiple movable blade edges of varying heights. The movable blade mechanism 5 rotates forward and reverse relative to the fixed blade mechanism 6, with the movable blades 51 corresponding to the fixed blades of the fixed blade assembly 67. This arrangement, by providing multiple fixed blade edges and multiple movable blade edges on the fixed blade mechanism 6 and the movable blade mechanism 5, results in a large number of edges, which, when combined with shearing action, achieve the effect of rapidly cutting and shredding kitchen waste. Among them, the fixed knife mechanism 6 is composed of multiple groups of fixed knife assemblies 67, each group of fixed knife assemblies 67 is composed of multiple fixed blades of different heights, and each fixed blade is provided with multiple fixed blade cutting edges; the movable knife mechanism 5 is composed of multiple groups of movable blades 51, and each group of movable blades 51 is provided with multiple movable blade cutting edges of different heights. When the movable knife mechanism 5 rotates forward and backward relative to the fixed knife mechanism 6, the movable blades 51 cooperate with the fixed blades to shear the garbage, so as to achieve the effect of quickly cutting and crushing the kitchen waste.

[0034] Specifically, the fixed blade mechanism 6 includes a fixed blade mounting base 60 and multiple fixed blade assemblies 67 spaced apart on the fixed blade mounting base 60. The fixed blade assemblies 67 include an upper fixed blade 61, a middle fixed blade 62, and a lower fixed blade 63. The upper fixed blade 61 is formed with a fixed blade edge 1 611, the middle fixed blade 62 is formed with a fixed blade edge 2 621, and the lower fixed blade 63 is formed with a fixed blade edge 3 631. This arrangement allows the upper fixed blade 61, the middle fixed blade 62, and the lower fixed blade 63, which are of different heights, to cooperate and shred garbage at different locations within the housing.

[0035] In actual application, the fixed blade mounting seat 60 is fixed to the inner wall of the housing 1 by screws.

[0036] Preferably, the fixed knife mounting seat 60 is an arc-shaped structure, and the shell 1 is a cylindrical structure. After the fixed knife mounting seat 60 is assembled, it fits on the inner wall of the shell 1; three groups of fixed knife assemblies 67 are arranged at intervals on the fixed knife mounting seat 60, and each group of fixed knife assemblies 67 includes an upper fixed blade 61, a middle fixed blade 62 and a lower fixed blade 63, wherein the upper fixed blade 61 and the middle fixed blade 62 can be one or two.

[0037] Furthermore, an arcuate groove 64 is formed on the outer wall of the upper fixed blade 61 and the middle fixed blade 62. When the movable blade mechanism 5 rotates forward and backward relative to the fixed blade mechanism 6, the garbage is blocked and sheared by the arcuate groove 64.

[0038] Furthermore, a groove 66 is formed on the lower fixed blade 63, and a wave-shaped tooth groove 65 is formed on the outer sides of the lower fixed blade 63. In this way, when the movable blade mechanism 5 rotates forward and backward relative to the fixed blade mechanism 6, the wavy tooth groove 65 and the groove 66 are used to block the garbage and then cut it.

[0039] Specifically, the movable blade mechanism 5 includes a movable blade mounting base 50 and two sets of movable blades 51 mirror-imaged on the movable blade mounting base 50. The movable blades 51 are formed with a first movable blade edge 511, a second movable blade edge 521, and a third movable blade edge 531. The first movable blade edge 511 corresponds to the first fixed blade edge 611, the second movable blade edge 521 corresponds to the middle fixed blade 62, and the third movable blade edge 531 corresponds to the third fixed blade edge 631. This arrangement improves crushing efficiency by cooperating with multiple sets of movable blade edges and fixed blade edges.

[0040] In actual application, the movable knife mounting seat 50 is fixed on the transmission shaft 4 by bolts 2 .

[0041] Furthermore, the movable blade 51 is formed with a first notch 52 and a second notch 53. The first notch 52 is provided corresponding to the upper fixed blade 61, and the second notch 53 is provided corresponding to the middle fixed blade 62. This arrangement facilitates cross-cutting with the upper fixed blade 61 and the middle fixed blade 62 through the first notch 52 and the second notch 53, thereby improving the crushing efficiency.

[0042] Specifically, the movable blades 51 have a gathering surface 55 on one side and a dispersing surface 56 on the other. When the dispersing surface 56 of one set of movable blades 51 is engaged in a cutting position corresponding to the fixed blades, the gathering surface 55 of the other set of movable blades 51 pulls the garbage and the fixed blades into a non-cutting position. This arrangement forces the garbage to gather inward at one end and disperse outward at the other, creating a balanced force distribution. This generates the maximum shear force on the garbage, thus enhancing shearing force. This also ensures concentrated cutting force, minimal resistance, and low power consumption, eliminating the high resistance and power consumption associated with multiple blade sets.

[0043] Furthermore, a stirring paddle 54 is provided on the movable blade mounting seat 50, and the stirring paddle 54 is located between the two sets of movable blades 51. In this way, the garbage in the housing 1 can be stirred by the stirring paddle 54 to improve the crushing efficiency.

[0044] Specifically, the gap between the first movable blade edge 511 and the first fixed blade edge 611 is d, the gap between the second movable blade edge 521 and the middle fixed blade 62 is c, the gap between the third movable blade edge 531 and the third fixed blade edge 631 is b, the gap between the third movable blade edge 531 and the bottom of the housing 1 is e, and the gap between the third fixed blade edge 631 and the bottom of the housing 1 is a. The gaps a, b, c, d, and e vary in size. This arrangement allows for the shearing of objects of varying sizes and thicknesses to improve comminution efficiency.

[0045] Furthermore, a sealing member 3 is provided between the transmission shaft 4 and the housing 1. This arrangement prevents leakage.

[0046] Example 2:

[0047] like Figure 9 As shown, the difference between the second embodiment and the first embodiment is that there is no stirring paddle 54 on the movable blade mounting seat 50 in the second embodiment. The rest of the structure and principle are the same as those in the first embodiment and will not be repeated.

[0048] Example 3:

[0049] like Figure 10 As shown, one side of the movable blade 51 is a concave gathering surface 55, and the other side of the movable blade 51 is an arc-shaped dispersion surface 56. The angle formed between the gathering surfaces 55 of the two groups of movable blades 51 is a pure angle a1.

[0050] The difference between the third embodiment and the first embodiment is that there is no stirring paddle 54 on the movable blade mounting base 50 in the third embodiment, and the positions of the two sets of movable blades 51 are different, forming different angles. The rest of the structure and principle are the same as those in the first embodiment and will not be repeated.

[0051] Example 4:

[0052] like Figure 11 As shown, one side of the movable blade 51 is a concave gathering surface 55, and the other side of the movable blade 51 is an arc-shaped dispersion surface 56. The angle formed between the dispersion surfaces 56 of the two groups of movable blades 51 is a pure angle a2.

[0053] The difference between the fourth embodiment and the first embodiment is that there is no stirring paddle 54 on the movable blade mounting base 50 in the fourth embodiment, and the positions of the two sets of movable blades 51 are different, forming different angles. The rest of the structure and principle are the same as those in the first embodiment and will not be repeated.
