[0021] Preferably, a crushing box 2 is fixedly installed on the upper end of the support cylinder 1, and a box cover 3 is threadedly connected to the upper end of the crushing box 2. A feeding mechanism 4 is arranged on the top of the box cover 3, and a carrying handle 15 is rotatably connected to the surface of the box cover 3. A crushing mechanism 5 is arranged inside the crushing box 2, and a discharging assembly for crushing the material and discharging it is arranged on one side of the crushing box 2. A power assembly for providing power to the crushing mechanism 5 is arranged at a corresponding position below the crushing box 2 and at the bottom of the support cylinder 1.

[0022] Preferably, the discharging assembly includes: a discharging port 6, a baffle 7, a sliding mechanism 8, a collecting bucket 9 and a pull ring 10, the discharging port 6 is opened on one side of the crushing box 2, a baffle 7 is arranged at a corresponding position on one side of the discharging port 6, sliding mechanisms 8 are arranged on both sides of the baffle 7, the baffle 7 is slidably connected to one side of the crushing box 2 through two groups of sliding mechanisms 8, a pull ring 10 is fixedly installed on the top of the baffle 7, and a collecting bucket 9 is arranged on one side of the baffle 7, wherein the large-diameter end of the collecting bucket 9 is fixedly connected to the two groups of fixed blocks 801 on both sides, the upper end of the large-diameter end of the collecting bucket 9 is flush with the top of the two groups of fixed blocks 801, and the lower end of the large-diameter end of the collecting bucket 9 is extended to the bottom of the fixed block 801 and fixedly connected to the surface of the crushing box 2.

[0023] Specifically, through the coordinated use of the baffle 7, the sliding mechanism 8, the collecting bucket 9 and the pull ring 10, the baffle 7 is pulled upward by using the pull ring 10, and the sliding mechanism 8 is convenient for controlling the baffle 7. Then, the baffle 7 is moved to the upper end of the discharge port 6, and the device is tilted to allow the crushed material to enter the collecting bucket 9 from the discharge port 6 and be poured out from one end of the collecting bucket 9, thereby reducing the discharge of dust inside the crushing box 2, reducing the dust standing time, and improving work efficiency. At the same time, the setting of the sliding mechanism 8 can facilitate the baffle 7 to slide on one side of the crushing box 2, and can also use the sliding mechanism to control the baffle 7 to descend, and block the discharge port 6, so that the device can facilitate the crushing of the material.

[0024] Preferably, the sliding mechanism 8 includes: a fixed block 801, a slide groove 802, a telescopic spring 803 and a slider 804, two groups of fixed blocks 801 are fixedly installed at both ends of one side of the crushing box 2, a slide groove 802 is opened on one side of the fixed block 801, and a telescopic spring 803 is fixedly installed on the inner wall of the upper end of the slide groove 802, and two groups of sliders 804 are fixedly installed at both ends of the baffle 7, the surface of the slider 804 is adapted to the interior of the slide groove 802, and the surface of the slider 804 is slidably connected to the inner wall of the slide groove 802, and the top of the slider 804 is fixedly connected to one end of the telescopic spring 803.

[0025] Specifically, through the coordinated use of the fixed block 801, the slide groove 802, the telescopic spring 803 and the slider 804, when discharging is required, the baffle 7 moves upward and will move the slider 804 upward inside the slide groove 802. The telescopic spring 803 is acted upon and the discharge port 6 is exposed, thereby facilitating the user to pour the crushed material into the collecting bucket 9. When the discharging is completed, the baffle 7 falls downward after the pull ring 10 is released. At the same time, the force generated by the telescopic spring 803 pushes the baffle 7 downward, so that the bottom of the baffle 7 can fit against the lower inner wall of one end of the collecting bucket 9, so that the material inside the crushing box 2 will not slip out of the collecting bucket 9.
