DETAILED DESCRIPTION
[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a multifunctional crushing and grinding device of the utility model comprises a grinding cylinder 1 and grinding balls 14, wherein the grinding balls 14 are arranged inside the grinding cylinder 1, and a grinding channel of a hemispherical structure is formed between the grinding cylinder 1 and the grinding balls 14, and a plurality of first push plates 13 are distributed in an annular structure in the opening above the grinding channel, and spaces for the first push plates 13 to move inward are formed between the first push plates 13, and second push plates 12 are arranged above the spaces of the first push plates 13 to block the spaces, a positioning ring 7 is arranged inside the grinding cylinder 1, and vertical rods 11 are installed on the top surfaces of the first push plates 13 and the second push plates 12, and the other ends of the vertical rods 11 are installed on the positioning ring 7.
[0021] In this embodiment, a transverse plate 2 is installed in the opening of the grinding cylinder 1, an axial hole is provided in the middle of the transverse plate 2, a motor 3 is installed on the transverse plate 2, the rotating shaft of the motor 3 passes through the axial hole and is installed with a shaft rod 15 through a coupling, the other end of the shaft rod 15 is installed on the grinding ball 14 through a connecting flange, a cylinder 4 is installed on the motor 3, a top plate 5 is installed on the piston rod of the cylinder 4, and a connecting rod 6 is installed between the top plate 5 and the positioning ring 7.
[0022] In this embodiment, a plurality of positioning grooves 9 are provided on the inner wall surface of the grinding cylinder 1, and a positioning block 8 is installed on the outer ring surface of the positioning ring 7 opposite to the positioning groove 9. The positioning block 8 is slidably set in the positioning groove 9. The cross-sections of the positioning groove 9 and the positioning block 8 are both arranged in a trapezoidal structure. The positioning ring can be positioned by the positioning groove and the positioning block so that the positioning ring can only move up and down along the positioning groove.
[0023] In this embodiment, the first push plate 13 and the second push plate 12 are both arranged in an arc-shaped structure, and the degree of the arc matches the degree of the arc of the outer ring of the grinding ball 14. The inner side surfaces of the first push plate 13 and the second push plate 12 are in contact with the outer ring surface of the grinding ball 14, and the outer side surfaces of the first push plate 13 and the second push plate 12 are in contact with the inner side surface of the grinding cylinder 1.
[0024] In this embodiment, a base 10 is installed at the bottom of the grinding cylinder 1, and a discharge pipe is also installed at the bottom of the grinding cylinder 1, and the materials after grinding can be discharged through the discharge pipe.
[0025] In this embodiment, the vertical rods 11 are all made of elastic metal material. After the first push plate enters the interior of the grinding channel, the grinding channel becomes smaller as it goes downward, so the first push plates will move closer to each other. During the process of moving closer, the vertical rods can bend, and the second push plate can block the space between the first push plates, so that the material can be fully pressed into the grinding channel.
[0026] When in use, the motor and the cylinder are started, and the motor can drive the shaft rod and the grinding balls to crush and grind the materials through the rotating grinding balls, while the cylinder is in a reciprocating telescopic state. After the piston rod on the cylinder is extended, it can drive the top plate to move upward, and the movement of the top plate drives the connecting rod and the positioning ring, so that the positioning ring moves upward stably along the positioning groove, and the movement of the positioning ring can synchronously drive the vertical rod, the first push plate and the second push plate, so that the first push plate and the second push plate are moved out of the opening of the grinding channel, and at this time, the materials can enter the interior of the grinding channel along the opening;
[0027] On the contrary, after the piston rod of the cylinder retracts, it can drive the top plate to move downward. The movement of the top plate drives the connecting rod and the positioning ring, and the positioning ring synchronously drives the first push plate and the second push plate through the vertical rod, so that the first push plate and the second push plate can enter the opening of the grinding channel, squeeze the material downward, and push the material directly into the interior of the grinding channel, avoiding the situation where the material does not enter the opening of the grinding channel, so as to ensure the grinding efficiency.
[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
