[0001] The utility model relates to the technical field related to grinding processing, in particular to a grinding cutter head assembly. Background Art

[0002] In the prior art, materials, medicinal materials, plants, etc. are generally ground by means of a cutter head, etc. However, the prior art grinding is mostly just a simple rotation, and the assembly of the entire grinding body and the accommodating cavity, etc., is just a grinding head placed in the assembly cavity with poor sealing, or a head cover is added. This method has a poor grinding effect. At the same time, for the object to be ground above the grinding head, it cannot be guided to the grinding head to achieve grinding in the assembly method of the head cover. Utility Model Content

[0003] The purpose of the utility model is to provide a grinding head assembly, the end of which is provided with a guide portion, and a downward guide path is formed, so that the to-be-ground object, including plants and other medicinal materials, at the assembly places of the grinding head assembly and the assembly cavity, etc., can enter the grinding head below the grinding body through the guide path to achieve grinding.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions.

[0005] Grinding head assembly, comprising:

[0006] A grinding body, wherein the grinding body is equipped with a rotating assembly for driving the grinding body to rotate;

[0007] A guide portion, the guide portion is located at an end of the grinding body, and the guide portion extends from the end toward the middle of the grinding body to form a first guide path facing downward;

[0008] A grinding tool head, wherein the grinding tool head is arranged below the guide portion to form a second guide path of the guide portion;

[0009] It also includes a guiding surface located above the guiding portion, the guiding surface is formed by extending outward through the grinding body, and when viewed from a top view, the guiding surface is a structure that is wide in the middle and narrow at both ends, and from the middle toward the two ends, the guiding surface forms a curved guiding surface.

[0010] In the present technical solution, a first guide path is added, which enables the grinding body assembly, the rotating body to be ground at the edge, and the grinding body with a belt located above the grinding body to enter the grinding head through the first guide path, thereby improving the grinding efficiency.

[0011] In the present technical solution, the grinding head itself also forms a second guide path, so that the object to be ground located between the guide portion and the grinding head is further guided to the bottom of the grinding head to complete the entire grinding operation.

[0012] In the present technical solution, the guiding surface extending outward forms a structure which is wide in the middle and narrow at both ends, as well as a curved guiding surface, which can not only guide the body to be ground at the outer end to the middle position, but also the curved guiding surface can form a similar circular surface during rotation, thereby improving the effect of introducing the external grinding body during rotation.

[0013] Preferably, the grinding body is a centrally symmetrical structure with the rotating assembly as the symmetry center, including a plurality of curved contact surfaces located at the periphery of the rotating center. Compared with a single curved surface, a plurality of centrally symmetrical curved contact surfaces not only increase the contact area with the object to be ground, but also centrally symmetrically, when the rotation speed is too high, may form a plurality of circular surfaces, thereby forming a guiding force to attract the object to be ground at the periphery.

[0014] Preferably, the curved contact surface is an arc surface, and several of the arc surfaces are arranged in parallel on the outer periphery of the center of the rotating component. In this technical solution, compared with other curved structures, the arc contact surface is easy to produce and process, and it is easier to form a circular surface during rotation, especially when the speed reaches a set position, forming a guiding force similar to a tornado. The parallel arrangement of several arc surfaces increases the contact surface area.

[0015] Preferably, there are at least two guiding surfaces, and the two guiding surfaces form a curved arc structure with opposite arc directions. In this technical solution, the directions of the arcs are opposite, and there are more guiding contact directions. At this time, during the rotation, an attractive guiding force in two directions is also formed.

[0016] Preferably, a third guide path is formed on the upper surface of the grinding body, and the third guide path is a downwardly inclined curved guide path from the end of the grinding body to the rotating assembly. In this technical solution, a third guide path is also formed on the upper surface of the grinding body, so that the external grinding material enters the grinding body from the high point of the grinding body through the third guide path, providing a basis for subsequent grinding.

[0017] Preferably, the end of the grinding body is provided with a notch with an opening facing downward to form the guide portion. In the technical solution, the guide portion is formed directly through the notch, and the notch has a large cross-sectional area and can accommodate more bodies to be ground. During rotation, the grinding body with the notch will also rub against the assembly body, etc., to complete the preliminary grinding.

[0018] Preferably, an inclined surface is formed inside the notch, so that the notch forms a diameter-expanding structure with a gradually increasing opening from top to bottom. In this technical solution, the inclined surface forms a diameter-expanding structure, and as the diameter-expanding volume increases, a guide is further formed to make it continue to move downward, and the diameter-expanding structure increases the accommodating volume, guiding more objects to be ground to enter.

[0019] Preferably, the notch is partially recessed toward the center of the grinding body to form a U-shaped avoidance guide groove. In this technical solution, the end of the grinding body is located above the guide surface and is provided with a U-shaped groove to provide space for the dispersion of excess grinding objects under the guide portion.

[0020] Preferably, the grinding body forms an overlap surface at the notch for assembling the grinding body. In this technical solution, the overlap surface is added, and when it is assembled with the assembly cavity later, the overlap surface is directly located above the assembly cavity, and then during rotation, the overlap surface drives the grinding body to rotate along the assembly cavity to perform grinding guidance and other tasks without adding assembly components, etc., which is convenient for assembly and has low production costs.

[0021] Preferably, the grinding blade is a sawtooth structure with the tip facing downward, and a plurality of the grinding blades are staggered along the thickness direction of the grinding body to form a grinding area. In this technical solution, the staggered sawtooth structure not only increases the grinding surface, but also increases the staggered grinding position, thereby improving the grinding efficiency.

[0027] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0028] See attached Figure 1-3As shown, the grinding head assembly in this embodiment includes a grinding body 100, and the grinding body 100 is equipped with a rotating assembly 200 that drives the grinding body 100 to rotate. In the prior art, the grinding body is rotated by the rotating assembly to increase the grinding effect, and the assembly method is also relatively conventional. For example, a motor is selected to form the rotating assembly, and then the center position of the grinding body is connected to the output shaft of the motor to achieve the effect of driving the rotation;

[0029] The grinding head assembly in this embodiment is generally used in the assembly cavity 300, assembled with the assembly cavity 300 carrying the object to be ground, and then rotated to make the grinding body produce a grinding effect to complete the grinding.

[0030] Compared with the conventional structure of the prior art, in this embodiment, a guide portion 110 is extended from the end of the grinding body 100, and the guide portion 110 extends from the end toward the middle position of the grinding body 10 to form a first guide path pointing downward; the guide portion 110 is used here to guide the object to be ground at the end to enter under the grinding body to complete the grinding, thereby improving the grinding efficiency of the object with grinding at the end.

[0031] A grinding head 120 is provided below the guide portion 110, and the grinding head 120 is provided below the guide portion 110 to form a second guide path of the guide portion 110; at this time, the grinding head 120 can also form another guide path, so that the accumulated objects to be ground will continue to move along the second guide path, avoiding accumulation and improving the grinding efficiency. After assembly, in order to allow the objects to be ground outside the assembly cavity 300 to enter the bottom of the grinding body to complete the grinding, a guide surface 130 located above the guide portion 110 is further included. The guide surface 130 is directly formed by extending outward from the grinding body 100. From a top view, the guide surface 130 is a structure that is wide in the middle and narrow at both ends, and from the middle toward the two ends, the guide surface 130 forms a curved guide surface.

[0032] In this embodiment, a first guide path is added, which enables the grinding body assembly, the rotating body to be ground at the edge, and the grinding body with a belt located above the grinding body to enter the grinding head through the first guide path, thereby improving the grinding efficiency.

[0033] In this embodiment, the grinding head itself also forms a second guide path, so that the object to be ground located between the guide portion and the grinding head is further guided to the bottom of the grinding head to complete the entire grinding operation.

[0034] In this embodiment, the guiding surface extending outward forms a structure that is wide in the middle and narrow at both ends, as well as a curved guiding surface, which can not only guide the outer end of the object to be ground to the middle position, but also the curved guiding surface can form a similar circular surface during rotation, thereby improving the effect of introducing the external grinding object during rotation.

[0035] The principle of the utility model is as follows:

[0036] By utilizing the guide portion, the guide surface and the grinding head, a horizontal inward guiding force, a vertical guiding force and a horizontal moving guiding force are respectively formed, so that the object to be ground on the outside of the assembly cavity 300, the contact point between the assembly cavity 300 and the guide portion, etc., can be introduced into the grinding head, thereby improving the overall grinding efficiency and allowing more objects to be introduced for grinding.

[0037] The grinding head assembly in the utility model can be directly assembled with the assembly cavity 300 (or the containing cavity, or the storage tank, etc.) with the grinding body for containing medicines, garbage, etc. through the guide part, etc., thereby improving the overall assembly efficiency.

[0038] When the utility model is used alone, the material to be ground can be poured into a set cavity, such as a trash can, and then the grinding head 120 is used for grinding, while the other structures also assist in guiding the poured material to be ground into the set cavity, thereby achieving multiple goals at one stroke.

[0039] In this embodiment, in order to cooperate with the rotation of the rotating assembly 200 and to improve the grinding efficiency, the grinding body 100 in this embodiment is a central symmetrical structure with the rotating assembly 200 as the symmetry center, including a plurality of curved contact surfaces 140 located at the periphery of the rotation center. Compared with one curved surface, a plurality of centrally symmetrical curved contact surfaces not only increase the contact area with the object to be ground, but also have central symmetry. When the rotation speed is too high, a plurality of circular surfaces may be formed, thereby forming a guiding force to attract the object to be ground at the periphery.

[0040] Furthermore, the curved contact surface 140 is an arc surface, and several of the arc surfaces are arranged in parallel on the outer periphery of the center of the rotating component. In this embodiment, compared with other curved structures, the arc contact surface is convenient for production and processing, and it is easier to form a circular surface during rotation, especially when the speed reaches a set position, forming a guiding force similar to a tornado. The parallel arrangement of several arc surfaces increases the contact surface area, and then along the outer periphery of the rotating component, there are several arc surfaces to attract the object to be ground, so that it enters the vicinity of the grinding head.

[0041] It can be directly seen from the accompanying drawings that there are at least two guide surfaces 130, and the two guide surfaces 130 form a curved arc structure with opposite arc directions. In this embodiment, the directions of the arcs are opposite, and the guiding contact directions are more. At this time, during the rotation, an attractive guiding force in two directions is also formed. During the rotation in this embodiment, first, two arc structures in opposite directions form two inward attractive forces, and then a number of curved contact surfaces are set on each of them, thereby increasing the contact and improving the contact with the object to be ground, which is equivalent to preliminary rough grinding.

[0042] Preferably, a third guide path is formed on the upper surface of the grinding body, and the third guide path is a downwardly inclined curved guide path from the end of the grinding body to the rotating assembly. In this technical solution, a third guide path is also formed on the upper surface of the grinding body, so that the external grinding material enters the grinding body from the high point of the grinding body through the third guide path, providing a basis for subsequent grinding.

[0043] In order to better form the guide, the end of the grinding body 100 is provided with a notch with an opening facing downward to form the guide portion 110. In this embodiment, the guide portion is formed directly through the notch. The cross-sectional area of ​​the notch is large, and it can accommodate more objects to be ground. During rotation, the grinding body with the notch will also undergo friction with the assembly body, etc., to complete the preliminary grinding. Furthermore, the notch with an opening facing downward guides the object to be ground into the notch, but because of its own gravity, it can automatically continue to move downward and enter the assembly cavity 300. In this embodiment, it is preferred to form a grinding cavity of a set height in the grinding body and the assembly cavity 300, so that the object to be ground that falls into the notch under gravity will be ground.

[0044] In order to make it closer to the grinding head 120, a slope 111 is formed inside the notch, so that the notch forms a diameter-expanding structure with a gradually increasing opening from top to bottom. In this embodiment, the slope forms a diameter-expanding structure, and as the diameter-expanding volume increases, a guide is further formed to make it continue to move downward, and the diameter-expanding structure increases the accommodating volume, guiding more objects to be ground to enter.

[0045] See attached Figure 1 As shown, the notch is partially recessed toward the center of the grinding body, forming a U-shaped avoidance guide groove 150. In this embodiment, the end of the grinding body is located above the guide surface and is provided with a U-shaped groove. During rotation, a U-shaped radial shearing area is formed with the notch in the vertical direction. The U-shaped groove can form an upward cavity, which moves the excessively accumulated materials to be ground below the guide upward, thereby achieving a certain degree of avoidance and dispersion. During rotation, due to the presence of the U-guide groove, cutting in another direction is also formed, thereby improving the cutting efficiency.

[0046] In order to facilitate assembly, the grinding body 100 forms a lap joint surface 160 at the notch for lap joint assembly of the grinding body. In this embodiment, the lap joint surface is added, and when it is assembled with the assembly cavity 300 later, the lap joint surface is directly located above the assembly cavity 300, and then during rotation, the lap joint surface drives the grinding body to rotate along the assembly cavity 300 to perform grinding guidance and other work, without adding assembly components, etc., which is convenient for assembly and has low production cost. Specifically, the lap joint surface 160 is one side of the notch, which is located outside the U-shaped avoidance guide groove, and the entire structure can be formed in one piece.

[0047] In this embodiment, in order to increase the grinding speed and area, the grinding blade 120 is a sawtooth structure with the tip facing downward, and a plurality of the grinding blades 120 are staggered along the thickness direction of the grinding body 100 to form a grinding area. In this embodiment, the staggered sawtooth structure not only increases the grinding surface, but also increases the staggered grinding position, thereby improving the grinding efficiency.

[0048] In the utility model, offset saw teeth are selected to form a grinding head, and then the overlapping surface 160 is matched to realize overlapping assembly. When the rotating component 200 rotates, the guide part 110, the guide surface 130, the curved contact surface 140, etc. form multiple guides, so that the external object to be ground is guided to the bottom of the grinding head to complete the grinding.

[0049] This embodiment can be used in garbage disposal, medicinal material grinding, plant treatment and other methods to improve grinding efficiency. In this embodiment, the grinding blade can also be formed at the bottom of the guide part 110, so that multiple grinding can be achieved to form a better grinding effect.
