Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0027] Combination Figure 1-Figure 8 The utility model discloses a raw material crusher for producing and processing magnesium carbon bricks, comprising a support frame 1 and a crushing box 2. The crushing box 2 is placed on the top of the support frame 1, and a feed hopper 3 is fixed on the top of the crushing box 2. Two rotating shafts 202 are rotatably connected at the top of the crushing box 2. A gear 2021 is provided at one end of the rotating shaft 202. A discharge hopper 203 is fixed below the rotating shaft 202 inside the crushing box 2. A screen hopper 204 is provided at the bottom of the discharge hopper 203. Slide plates 2041 are fixed on both sides of the screen hopper 204, which slide in a slideway provided inside the crushing box 2. A screen mesh 2043 is fixed on the inside of the screen hopper 204. One side of the screen hopper 204 passes through the crushing box 2. A driving component 4 is provided, and a discharging platform 205 is fixed at the outlet position of the crushing box 2 on one side below the screen bucket 204, and a collecting box 5 is placed at the position below the crushing box 2 and corresponding to the discharging platform 205. The driving component 4 includes a bracket 401 fixed to one side of the crushing box 2, a motor 402 is fixed to one side of the bracket 401, and the motor 402 is connected to a rotating wheel 403 through the bracket 401, and an adjusting rod 404 is rotatably connected to the rotating wheel 403, and a moving block 405 is rotatably connected to the other end of the adjusting rod 404, and the moving block 405 slides in the opening of the side wall of the crushing box 2 and is fixedly connected to one end of the screen bucket 204.

[0028] Specifically, in this case, when in use, the control panel on the side wall of the crushing box 2 is operated to start the gear 2021 to engage and rotate relative to each other, and the motor 402 on the bracket 401 is started at the same time, and the raw material is put into the feed hopper 3. The rotation of the gear 2021 drives the rotating shaft 202 to rotate for crushing, and the crushed raw material passes through the discharge hopper 203 and falls into the screening bucket 204. When the motor 402 is started, it will drive the rotating wheel 403 to rotate, and the adjusting rod 404 will move regularly accordingly, driving the moving block 405 to swing back and forth, and the moving block 405 drives the screening bucket 204 to swing back and forth. The slides 2041 on both sides of the screening bucket 204 slide in the slideway opened inside the crushing box 2, thereby achieving the screening effect. The screened raw material falls into the collection box 5 directly below, and the raw material that has not passed the screening falls into another collection box 5 through the discharge platform 205 as it swings. The component has a simple structure and is easy to maintain. It can improve the raw material screening accuracy and can well meet the requirements of the magnesia-carbon brick production process for raw material crushing and screening.

[0029] The utility model is further described below in conjunction with embodiments.

[0030] Embodiment 1:

[0031] Combination Figure 4-Figure 5 A groove is provided on the inner side of the screen bucket 204, and a screen 2043 is provided in the groove. The screen 2043 is inserted into the opening of the groove. A locking block 2044 is provided at the opening of the groove of the screen bucket 204, and the locking block 2044 fits with the screen 2043. The screen 2043 is designed to be a card slot type and is fixed with the locking block 2044. The installation is simple and quick, and stability and firmness are guaranteed. The screen 2043 can be disassembled and maintained conveniently, or replaced with different specifications to meet different production needs.

[0032] Rubber blocks 2042 are fixed on both sides of the slide plate 2041. Fixing rubber blocks 2042 on both sides of the slide plate 2041 can provide buffering and protection, prevent components from being damaged, and extend the service life of components.

[0033] Embodiment 2:

[0034] Combination Figure 2-Figure 7 There are crushing blocks 201 fixed on the inner wall of the crushing box 2 on both sides of the rotating shaft 202, and crushing wheels 2022 are distributed on the rotating shaft 202. Using the crushing wheels 2022 for crushing can achieve efficient crushing in a short time, improve production efficiency and output, and help to ensure the consistency and stability of product quality.
