[0031] Example 1

[0032] like Figures 1-3 As shown, the present invention proposes a vertical impact crusher, comprising a mounting platform 1, a discharge port 2 located at the top of the mounting platform 1, a guide platform 3 located at the top of the mounting platform 1 and at the axis, a crushing chamber 4 located at the top of the discharge port 2, a distribution chamber 5 located at the top of the crushing chamber 4, a feed hopper 6 located at the top of the distribution chamber 5, a dust prevention mechanism, a feeding adjustment mechanism, and a feeding frame 804.

[0033] The dust prevention mechanism is located inside the material distribution chamber 5 and is used to shield the feeding position during the material conveying process.

[0034] The feeding adjustment mechanism is installed on the dust prevention mechanism and is used to adjust the amount of material conveyed each time depending on the type of crushed material.

[0035] The feeding rack 804 is mounted on the dust prevention mechanism. A feeding plate 909 is slidably mounted on the inner side of the feeding rack 804. A sliding plate is slidably mounted on the inner side of the feeding plate 909. There are two sliding plates symmetrically arranged about the feeding plate 909. The feeding rack 804 has four chambers, and each chamber has a feeding plate 909. The feeding plate 909 slides on the feeding rack 804 to control the amount of material received. When the feeding plate 909 moves, the sliding plate is always in contact with the inner wall of the feeding rack 804 under the action of the feeding adjustment mechanism.

[0036] The impact crushing assembly includes a fixed frame 701, a motor 702, a rotating shaft 703, and a synchronous pulley 704. The fixed frame 701 is located on the outside of the mounting platform 1, the motor 702 is located on the inside of the fixed frame 701, the rotating shaft 703 is located at the output end of the motor 702, the synchronous pulley 704 is located at the bottom of the rotating shaft 703, a synchronous belt 705 is located on the outside of the synchronous pulley 704, a synchronous pulley 706 is located at the end of the synchronous belt 705 away from the synchronous pulley 704, a connecting shaft 707 is located at the axis of the synchronous pulley 706, an impeller 708 is located at the top of the connecting shaft 707, a circumferential impact plate 710 is located on the inside of the crushing chamber 4, a distribution cone 709 is located at the top of the impeller 708, and a distribution plate 711 is located on the inside of the distribution chamber 5. After falling into the distribution chamber 5, the material lands on the distribution plate 711. The distribution plate 711 is truncated cone-shaped with a hollow center, so the material is divided into two parts. One part falls directly down along the outer slope, and the other part falls from the hollow part onto the distribution cone 709. Then, it slides down the distribution cone 709 onto the impellers 708 around the perimeter. The motor 702 starts and drives the shaft 703 to rotate. The shaft 703 drives the synchronous wheel 704 to rotate. The synchronous wheel 704 drives the synchronous wheel 706 to rotate via the synchronous belt 705. The synchronous wheel 706 drives the impeller 708 to rotate via the connecting shaft 707. When the impeller 708 rotates at high speed, it launches the material that has fallen onto it and impacts and crushes the material that falls directly. The crushed material slides out from the discharge port 2 through the guide platform 3 for collection.

[0037] The dust control mechanism includes a connecting frame 801, a second motor 802, and a second rotating shaft 803. The connecting frame 801 is located on the outside of the material distribution chamber 5, the second motor 802 is located on the inside of the connecting frame 801, and the second rotating shaft 803 is located at the output end of the second motor 802. The outside of the second rotating shaft 803 is connected to the shaft center of the feeding frame 804. A baffle 805 is provided on the inside and top of the material distribution chamber 5, and the inside of the baffle 805 is in contact with the outside of the feeding frame 804. Furthermore, the partition 805 can completely cover one chamber of the feeding frame 804. After the motor 802 starts, it drives the rotating shaft 803 to rotate. The rotating shaft 803 drives the feeding frame 804 to rotate and transport the material in the feed hopper 6 to the distribution chamber 5. During this process, the chamber of the feeding frame 804 can only be fed and discharged when it moves to the top and bottom. In addition, during the crushing process, the dust cannot fly out due to the obstruction of the feeding frame 804 and the partition 805.

[0038] Example 2

[0039] like Figures 4-6 As shown, this utility model proposes a vertical impact sand making machine. Compared with Embodiment 1, this embodiment details the structure of the feeding adjustment mechanism.

[0040] The feeding adjustment mechanism includes a power component and an adjustment component. The power component is threaded onto the material distribution chamber 5 and is used to drive the adjustment component to move. The adjustment component is located at the end of the power component and is used to adjust the amount of material fed each time according to different materials. The power component includes a threaded rod 901, a power rod 902, an adjustment disc 903, and a rotating rod 904. The threaded rod 901 is threaded onto the outer wall of the material distribution chamber 5. The power rod 902 is located at the end of the threaded rod 901. The adjustment disc 903 is rotatably located at the end of the threaded rod 901 away from the power rod 902. The rotating rod 904 is rotatably located on the side of the adjustment disc 903. Four rotating rods 904 are arranged in a ring around the adjustment disc 903. When the power rod 902 is rotated, it moves under the action of the material distribution chamber 5, thereby driving the adjustment disc 903 to move. When the adjustment disc 903 moves, it drives the four rotating rods 904 to rotate synchronously. The adjustment assembly includes a sliding block 905, a cover plate 906, a rotating disk 907, and a slide 908. The sliding block 905 is rotatably mounted on the end of the rotating rod 904 away from the adjustment disk 903. The cover plate 906 is located on both sides of the sliding block 905. The rotating disk 907 is located at both ends of the feeding frame 804. The slide 908 is located on the rotating disk 907, and four slide 908s are arranged in a ring around the rotating disk 907. The inner side of the slide 908 is slidably connected to the outer side of the sliding block 905. The side of the sliding block 905 away from the rotating rod 904 is connected to the end of the feeding plate 909. A telescopic rod is provided on the inner side of the feeding plate 909. Multiple telescopic rods are arranged at equal intervals within the feeding plate 909. Springs are installed on the outer side of the telescopic rods. The ends of the telescopic rods are connected to the ends of the sliding plates. When the rotating rod 904 rotates, it drives the sliding block 905 to slide within the slide groove 908. During the sliding, it drives the feeding plate 909 to move within the cavity of the feeding rack 804. During the movement, the sliding plates on both sides extend and retract under the action of the springs, thus always fitting against the inner wall of the feeding rack 804. The cover plate 906 always closes the feeding rack 804 when the sliding block 905 moves, thus preventing material from getting stuck in the slide groove 908 or leaking below the feeding plate 909 during feeding, which would affect the operation of the device.

[0041] In summary, when using this utility model, depending on the type of material to be crushed, the power rod 902 is rotated. As the power rod 902 rotates, it moves under the action of the material distribution chamber 5, thereby driving the adjusting plate 903 to move. When the adjusting plate 903 moves, it drives the four rotating rods 904 to rotate synchronously. When the rotating rods 904 rotate, they drive the sliding block 905 to slide within the sliding groove 908. During this sliding motion, the feeding plate 909 moves within the chamber of the feeding frame 804. During this movement, the sliding plates on both sides extend and retract under the action of springs, thus always remaining in contact with the inner wall of the feeding frame 804. After the feeding chamber of the feeding frame 804 is adjusted, the material is poured into the feed hopper 6. Motor 1 702 and Motor 2 802 are then started. Motor 2 802 drives the rotating shaft 2 803 to rotate, which in turn drives the feeding frame 804 to rotate, conveying the material in the feed hopper 6 to the material distribution chamber 5. During the process, the feeding rack 804 and the baffle 805 block the connection between the material distribution chamber 5 and the feed hopper 6, preventing dust from flying out. After the material falls into the material distribution chamber 5, it lands on the material distribution plate 711. Under the action of the material distribution plate 711, part of the material falls directly down along the outer slope, and the other part falls from the hollow part onto the material distribution cone 709, and then slides down onto the impellers 708 around the perimeter. The motor 702 drives the shaft 703 to rotate, the shaft 703 drives the synchronous wheel 704 to rotate, the synchronous wheel 704 drives the synchronous wheel 706 to rotate through the synchronous belt 705, and the synchronous wheel 706 drives the impeller 708 to rotate through the connecting shaft 707. When the impeller 708 rotates at high speed, it launches the material that falls on it and impacts and crushes the material that falls directly. The crushed material slides out from the discharge port 2 through the guide platform 3 for collection.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
