DETAILED DESCRIPTION

[0026] The following describes a cone-type stone crusher provided by the present invention in detail with reference to the accompanying drawings and specific embodiments. It is also noted that, to provide a more detailed description, the following embodiments are best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative implementations. Furthermore, the accompanying drawings are only provided to more specifically describe the embodiments and are not intended to limit the present invention.

[0027] like Figure 1 - Figure 6 As shown, the embodiment of the present invention provides a cone-type stone crusher, comprising: a crusher body 1, in which a static cone 4 and a dynamic cone 5 are provided, which are movably connected to each other, wherein the static cone 4 is fixed to the top of the crusher body 1, and the dynamic cone 5 is connected to the bottom of the static cone 4 by rotating at a certain eccentric angle and located inside the static cone 4. The outer wall of the dynamic cone 5 cooperates with the inner wall of the static cone 4 to squeeze and crush the stone. This device is a prior art, so the specific structure is not shown in detail in the drawings of the specification; a hopper 7 is fixed to the top of the crusher body 1, and the dynamic cone 5 is connected to the bottom of the static cone 4 by rotating at a certain eccentric angle and located inside the static cone 4. 2 is fixed to the top of the static cone 4, and a clamping seat 6 for supporting the hopper 7 is provided on the inner side wall of the fixed seat 2. The fixed seat 2 is annular in structure, and an annular seat is provided on the side for overlapping the top of the crusher body 1. The inner side wall of the clamping seat 6 abuts against the outer side wall of the hopper 7 to support the hopper 7; there are multiple protective components 3, which include a mounting seat 9 fixed to the top of the fixed seat 2 and a protective plate 10 movably connected to the mounting seat 9. The protective plates 10 on the multiple protective components 3 cooperate with each other to form a circular plate body for covering the top area of ​​the hopper 7.

[0028] By setting up the protective component 3, effective sealing and protection of the top area of ​​the hopper 7 is achieved. Without affecting the discharge of materials, the stones that are squeezed and fly during the crushing process are blocked to prevent the stones from flying out of the crusher body 1 and causing personal injury to nearby workers; the protective component 3 is a detachable structure as a whole, and can be quickly disassembled and replaced after it is damaged, thereby optimizing the maintenance process and improving work efficiency.

[0029] like Figure 6 As shown, the protective plate 10 has a fan-shaped structure, and a rotating assembly 11 is provided on the side of the bottom near the arc end. The rotating assembly 11 includes a wedge block fixedly connected to the protective plate 10, and a sleeve fixedly connected to the wedge block; a mounting groove 16 is provided on the inner side wall of the mounting seat 9 near the bottom, and a rotating shaft is fixed inside the mounting groove 16, and the rotating shaft and the sleeve are rotatably connected.

[0030] By setting the protective plate 10 into a fan-shaped structure, it is not only convenient for multiple protective plates 10 to cooperate with each other to form a complete circular plate body, covering the top of the hopper 7 and reducing the risk of gravel splashing, but also ensures the compactness of the structure and the flexibility of installation. The rotating assembly 11 set at the bottom includes a fixed connection between a wedge block and a sleeve, so that the protective plate 10 can rotate smoothly around the rotating shaft, which is convenient for quickly opening or closing the top of the hopper 7 when needed, facilitating feeding and cleaning. During use, the protective plate 10 is limited to flip upward by the arc-shaped end wall of the protective plate 10 abutting against the inner side wall of the mounting seat 9. Under the abutment of the side walls of the two, when the protective plate 10 flips upward to the maximum angle, its plate body and the side wall of the mounting seat 9 are in a mutually perpendicular state (i.e., in the horizontal direction).

[0031] like Figure 3 and Figure 5 As shown, a card slot 14 is provided at the bottom of the mounting seat 9, and the card slot 14 is slidably connected with the top of the side wall of the fixing seat 2, wherein the card slot 14 has a curve design with the same curvature as the side wall of the fixing seat 2; it also includes a locking bolt 15, which is threadedly connected with the outer side wall of the card slot 14, and an annular groove 8 is provided on the outer side wall of the fixing seat 2 near the top. The locking bolt 15 is configured to pass through the side wall of the card slot 14 and abut against the bottom wall of the annular groove 8 when the fixing seat 2 is fixed.

[0032] Through the sliding connection design of the card slot 14 at the bottom of the mounting seat 9 and the side wall of the fixing seat 2, the mounting seat 9 can be accurately aligned and fixed on the fixing seat 2. At the same time, the locking bolt 15 passes through the side wall of the card slot 14 and abuts against the bottom wall of the annular groove 8 on the fixing seat 2, thereby achieving double locking, effectively preventing the protective component 3 from accidentally loosening or falling off during operation.

[0033] like Figure 3As shown, it also includes a protective shell 12, which is fixed on the top of the protective plate 10. The protective shell 12 is an open structure, and the opening faces the mounting seat 9; it also includes a tension spring 13, the two ends of which are respectively fixedly connected to the inner wall of the mounting seat 9 and the inner side of the end wall of the protective shell 12 away from the opening, and the tension spring 13 is completely located inside the protective shell 12.

[0034] The protective shell 12 not only provides additional protection for the protective plate 10, preventing external impacts from directly affecting the protective plate 10, but its design, with its opening facing the mounting seat 9, also facilitates the installation and securing of the tension spring 13, while also protecting the tension spring 13 from damage caused by impacts from rocks during the unloading process. The tension spring 13, acting as an elastic element, connects the mounting seat 9 and the protective shell 12 at both ends, providing a stable closing force when the protective plate 10 is closed. Furthermore, when the protective plate 10 needs to be opened, its elastic potential energy facilitates rapid opening, improving operational convenience.

[0035] The protective plate 10 and the protective shell 12 are made of the same polymer resin material, which not only has excellent wear resistance and corrosion resistance, and can withstand the erosion of harsh working environments such as gravel and dust, but also has good impact resistance and lightweight characteristics, which reduces the overall weight of the equipment and reduces manufacturing costs, while ensuring the safety of operators.

[0036] The technical solution provided by the present invention is that, during the stone crushing process, the stone to be crushed is thrown into the crusher body 1 from above, and under the action of the gravity of the falling stone, the protective plate 10 pulls the tension spring 13 to rotate downward, thereby generating a gap so that the stone can smoothly fall into the hopper 7 and be guided to the inside of the crusher body 1 to be squeezed and crushed by the static cone 4 and the dynamic cone 5. Under the tension of the tension spring 13, the protective plate 10 always has a tendency to automatically reset to the horizontal position. Through the cooperation of multiple protective plates 10, a vertical circular vertical projection protective structure is always formed on the top of the crusher body 1, and the gap between two adjacent protective plates 10 is filled with falling stone, which effectively blocks the stones flying from the crusher body 1 and improves the safety of the construction site. It should be noted that since both sides of the protective plate 10 are impacted by stones, damage is inevitable. When the protective plate 10 is damaged, the protective component 3 connected to the protective plate 10 is replaced as a whole. It is only necessary to screw the locking bolt 15 to disengage it from the annular groove 8, and then lift the mounting base 9 as a whole upward to disengage the slot 14 from the side wall of the fixing base 2. The operation is convenient and quick.

[0037] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
