Description

Technical Field

[0001] This utility model relates to the field of mechanical crusher technology, and in particular to a mechanical crusher. Background Technology

[0002] Crusheres are widely used in many sectors such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries. Commonly used crushing machinery includes jaw crushers, impact crushers, air-classifying crushers, hammer crushers, cone crushers, roller crushers, and compound crushers. Jaw crushers are characterized by a large crushing ratio, uniform product particle size, simple structure, reliable operation, easy maintenance, and economical operating costs. Impact crushers can process materials with side lengths of 100-500 mm and a compressive strength up to 350 MPa, offering advantages such as a large crushing ratio and cubic particle size after crushing. Impact crushers are suitable for crushing medium-hard materials, offering advantages such as high production capacity and small output particle size. Many existing mechanical crushers are difficult to move, therefore, a mechanical crusher is used to crush raw materials.

[0003] Existing technologies, such as patent CN208427191U, disclose a mechanical crusher. This patent uses a base, with a crushing box fixedly connected to the top of the base. The upper surface of the crushing box has a feed inlet, and a first motor is fixedly connected to the side of the crushing box via a pad. A first bearing is fixedly connected to the side of the inner wall of the crushing box, and the output shaft of the first motor is fixedly connected to the inner wall of the first bearing. A rotating shaft is fixedly connected to the inner wall of the first bearing. This utility model solves the problem that many existing mechanical crushers cannot completely crush materials, requiring manual crushing of some raw materials after the crusher has been crushed, which not only reduces work efficiency but also increases working costs.

[0004] In daily operation, during the use of the equipment, there is a problem that the raw materials inside the hopper cannot quickly come into contact with the crusher, making it difficult to crush the raw materials inside the hopper. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where equipment is unable to quickly crush raw materials, and to propose a mechanical crusher.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mechanical crusher, comprising a main body, a support frame, a discharge pipe, a material hopper, a crusher, and an extrusion device. The support frame is fixedly connected to the lower surface of the material hopper, the discharge pipe is fixedly connected to the lower surface of the main body, the material hopper is fixedly connected to the upper surface of the main body, and the crusher is fixedly installed inside the main body. The extrusion device is fixedly disposed inside the material hopper, and includes a connecting frame and a pressure plate. The connecting frame is slidably connected inside the material hopper, the pressure plate is disposed inside the connecting frame, a rotating block is fixedly connected inside the connecting frame, and the pressure plate is rotatably connected inside the rotating block. A sliding hole is provided on the surface of the material hopper, and a connecting block is fixedly connected to one end of the connecting frame, the connecting block being slidably connected inside the sliding hole.

[0007] Furthermore, two limiting blocks are fixedly connected to the side of the material hopper, and threaded rods are rotatably connected inside the two limiting blocks. By setting the limiting blocks, the threaded rods can be limited, reducing the difficulty of limiting the movement of the threaded rods during equipment use.

[0008] Furthermore, the two ends of the threaded rod are fixedly connected to fixing blocks, and the threaded rod is threadedly connected inside the connecting blocks. The fixing blocks facilitate the positioning of the threaded rod.

[0009] Furthermore, a servo motor is fixedly connected to the lower end of the threaded rod, and the servo motor is fixedly connected to the surface of the material hopper.

[0010] Furthermore, an auxiliary component is fixedly installed inside the pressure plate. The auxiliary component includes a mounting block and a positioning groove. The positioning groove is opened inside the connecting frame. The mounting block is fixedly connected to the upper surface of the pressure plate. A pull groove is opened inside the mounting block. A positioning plate is slidably connected inside the pull groove. The positioning plate is inserted into the positioning groove. By setting the positioning plate, the pressure plate can be limited, reducing the situation where the pressure plate is difficult to limit during use.

[0011] Furthermore, a first spring is fixedly connected to the end of the positioning plate away from the positioning groove, and the end of the first spring away from the positioning plate is fixedly connected inside the groove. The first spring is provided to facilitate the application of a reset force to the positioning plate.

[0012] Furthermore, a pull block is fixedly connected to the upper surface of the positioning plate near the first spring end. The pull block is slidably connected inside the pull groove. The pull block is provided to facilitate the movement of the positioning plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up an extrusion device, the raw materials inside the material hopper are effectively moved, which plays a role in squeezing the material inside the material hopper downward. This reduces the situation where the raw materials inside the material hopper are difficult to contact the crusher quickly when the existing equipment is in use, which makes it difficult to crush the raw materials inside the material hopper. This extrusion device realizes the rapid feeding of raw materials, facilitates the crushing of raw materials by the equipment, and improves the practicality of the equipment.

[0015] 2. In this utility model, by setting an auxiliary component, the pressure plate is effectively limited, which plays a role in installing and positioning the pressure plate. This reduces the situation where the pressure plate is difficult to detach from the connecting frame during use, making it difficult for the equipment to quickly squeeze the raw materials. This auxiliary component enables the quick installation and disassembly of the pressure plate, improving the practicality of the equipment. Attached Figure Description

[0023] The main body 1 is made of high-strength cast iron, with multiple layers of sound insulation boards and shock-absorbing rubber pads inside, which can effectively reduce noise and vibration during the crushing process; the support frame 2 is welded from thickened steel; the discharge pipe 3 is designed with an inclined shape, with a smooth inner wall and a gradually narrowing diameter, using gravity and material flow inertia to quickly discharge the crushed material; the material hopper 4 is inverted conical in shape and made of wear-resistant stainless steel, and its volume is designed according to the crusher's processing capacity to effectively store the raw materials to be crushed; the crusher 5 consists of a rotating extrusion disc, which is made of high-hardness alloy material and undergoes a special heat treatment process, resulting in strong wear resistance and high crushing efficiency.

[0024] The specific settings and functions of the extrusion device 6 and auxiliary components 7 will be discussed below.

[0025] In this embodiment: the extrusion device 6 is fixedly installed inside the material hopper 4. The extrusion device 6 includes a connecting frame 61 and a pressure plate 62. The connecting frame 61 is slidably connected inside the material hopper 4. The connecting frame 61 is a rectangular metal frame with rounded edges to reduce friction with the inner wall of the material hopper 4 and ensure smooth sliding. The pressure plate 62 adopts an arc-shaped design with anti-slip ridges distributed on the surface to increase friction with the material and improve the extrusion effect. The pressure plate 62 is installed inside the connecting frame 61. A rotating block 63 is fixedly connected inside the connecting frame 61. The pressure plate 62 is rotatably connected inside the rotating block 63. A sliding hole 64 is opened on the surface of the material hopper 4. A connecting block 65 is fixedly connected to one end of the connecting frame 61. The connecting block 65 is slidably connected inside the sliding hole 64.

[0026] Specifically, two limiting blocks 66 are fixedly connected to the side of the material hopper 4, and threaded rods 67 are rotatably connected inside the two limiting blocks 66.

[0027] In this embodiment: by setting the limiting block 66, the threaded rod 67 can be limited, reducing the difficulty of limiting the movement of the threaded rod 67 during use.

[0028] Specifically, the two ends of the threaded rod 67 are fixedly connected to the fixing blocks 68. The threaded rod 67 is threadedly connected inside the connecting block 65. The fixing blocks 68 are provided to facilitate the positioning of the threaded rod 67.

[0029] Specifically, a servo motor 69 is fixedly connected to the lower end of the threaded rod 67, and the servo motor 69 is fixedly connected to the surface of the material hopper 4.

[0030] In this embodiment: An auxiliary component 7 is fixedly installed inside the pressure plate 62. The auxiliary component 7 includes a mounting block 71 and a positioning groove 73. The positioning groove 73 is opened inside the connecting frame 61. The mounting block 71 is fixedly connected to the upper surface of the pressure plate 62. A pull groove 72 is opened inside the mounting block 71. A positioning plate 74 is slidably connected inside the pull groove 72. The positioning plate 74 is inserted and connected inside the positioning groove 73.

[0031] In this embodiment, by setting the positioning plate 74, the pressure plate 62 can be limited, reducing the difficulty of limiting the pressure plate 62 during use.

[0032] Specifically, a first spring 76 is fixedly connected to the end of the positioning plate 74 away from the positioning groove 73. The end of the first spring 76 away from the positioning plate 74 is fixedly connected to the inside of the pull groove 72. The first spring 76 is provided to facilitate the application of a reset spring force to the positioning plate 74.

[0033] Specifically, a pull block 75 is fixedly connected to the upper surface of the positioning plate 74 near the first spring 76. The pull block 75 is slidably connected inside the pull groove 72. The pull block 75 is provided to facilitate the movement of the positioning plate 74.

[0034] Working Principle: During standby, the user places the raw material to be crushed into the material hopper 4 and starts the equipment. The crusher 5 inside the main body 1 operates to crush the raw material, which is then discharged through the discharge pipe 3. During operation, when the user places the raw material into the material hopper 4, the pressure plate 62 engages with the connecting frame 61, and the servo motor 69 is started. The servo motor 69 drives the threaded rod 67 to rotate within the limit block 66. The rotation of the threaded rod 67 then moves the connecting block 65 within the sliding hole 64. The movement of the connecting block 65 causes the connecting frame 61 and the pressure plate 62 to press the material inside the material hopper 4 downwards. By setting up the pressing device 6, the raw material inside the material hopper 4 is effectively moved, effectively pressing it downwards. This reduces the difficulty in quickly contacting the crusher 5 with the raw material inside the material hopper 4, which is a problem in existing equipment, making it difficult to crush the raw material. This pressing device 6 enables rapid material discharge, facilitating the crushing of the raw material and improving the practicality of the equipment.

[0035] When the equipment is in use, the user pulls the pull block 75 to move the positioning plate 74 inside the pull groove 72 when the pressure plate 62 is moved. The movement of the positioning plate 74 compresses the first spring 76, generating elastic force. Then the positioning plate 74 disengages from the positioning groove 73, and the pressure plate 62 is unrestrained. Pulling the pressure plate 62 inside the connecting frame 61 allows it to rotate and disengage from the connecting frame 61. By setting the auxiliary component 7, the pressure plate 62 is effectively limited, which plays a role in the installation and positioning of the pressure plate 62. This reduces the situation where the pressure plate 62 is difficult to disengage from the connecting frame 61 during the use of existing equipment, making it difficult for the equipment to quickly squeeze the raw materials. This auxiliary component 7 enables the quick installation and disassembly of the pressure plate 62, improving the practicality of the equipment.
