[0023] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0024] As Figures 1-4 shown, a firecracker crushing and dispersing device includes a base frame 1, on which are provided:

[0025] A hopper 2, in which a crushing roller 21 is rotatably arranged;

[0026] A material distribution plate 3, a receiving groove 11 is formed in the base frame 1 on the lower side of the hopper 2, leakage holes 31 are arranged in a rectangular array on the material distribution plate 3, and the material distribution plate 3 is arranged in the receiving groove 11 to be separated to form a debris receiving cavity 111 and a particle receiving cavity 112. The particle receiving cavity 112 is located on the lower side of the debris receiving cavity 111, and a drainage part 12 communicating with the particle receiving cavity 112 is formed on the base frame 1.

[0027] Specifically, as Figure 2As shown in the figure, a hopper 2 is fixedly arranged on the upper part of the base frame 1. A set of shredding rollers 21 that rotate to shred firecrackers are arranged in the hopper 2. The receiving groove 11 of the base frame 1 is located vertically below the hopper 2 to receive and collect the firecracker scraps shredded by the shredding rollers 21. A distributing plate 3 is arranged in the receiving groove 11 to divide the receiving groove 11 into a debris receiving cavity 111 and a particle receiving cavity 112. When the firecracker scraps fall by gravity and enter the receiving groove 11, the larger firecracker paper scraps are blocked by the distributing plate 3 and stay in the debris receiving cavity 111. The smaller gunpowder particles or small paper scraps will flow down along the leakage holes 31 following the water droplets extruded from the firecrackers and enter the particle receiving cavity 112 to be collected, thus completing the separate collection of the firecracker scraps according to particle size, improving the processing efficiency of the firecracker scraps. The water liquid in the particle receiving cavity 112 will also be discharged along the drainage part 12 to remove the sewage, and the drainage part 12 is used to avoid the pollution problem caused by the water extruded from the firecrackers carrying gunpowder particles and overflowing.

[0028] Furthermore, a filter element 5 is arranged in the drainage part 12. When the water liquid in the particle receiving cavity 112 is discharged along the drainage part 12, the gunpowder particles or small paper scraps will be blocked by the filter element 5 in the particle receiving cavity 112, thus avoiding the pollution problem caused by the gunpowder particles flowing out with the sewage and improving the cleanliness during the shredding and destruction process.

[0029] Still further, the bottom of the particle receiving cavity 112 of the base frame 1 is inclined, and the drainage part 12 is connected to the lower end of the bottom of the particle receiving cavity 112, thereby improving the drainage efficiency of the drainage part 12 for the particle receiving cavity 112. Secondly, an opening communicating with the particle receiving cavity 112 is provided on the base frame 1, and a plugging member 4 is slidably arranged to plug the opening. The plugging member 4 can be taken out to clean and take out the collected objects in the particle receiving cavity 112.

[0030] In the above technical solution, the distributing plate 3 is used to separate the firecracker scraps received in the receiving groove 11. The larger scraps are located in the debris receiving cavity 111, while the smaller gunpowder particles and water liquid are first collected in the particle receiving cavity 112. Subsequently, the water liquid is discharged along the drainage part 12 to complete the separate discharge of the gunpowder particles and the water liquid. While improving the processing efficiency of the firecracker scraps, it can also avoid the pollution problem caused by the water extruded from the firecrackers carrying gunpowder particles and overflowing.

[0031] As a further embodiment provided by the present utility model, the distributing plate 3 is arranged in an inclined shape, and the distributing plate 3 is vertically slidably arranged in the receiving groove 11 through a first sliding part 32 provided thereon. The distributing plate 3 is driven to slide vertically so that the lower end of the distributing plate 3 is flush with the secondary discharge port 113 of the receiving groove 11.

[0032] Specifically, as Figure 2As shown in the figure, a secondary discharge port 113 is provided at the upper end of the receiving groove 11, and the distribution plate 3 is arranged obliquely. When the distribution plate 3 is driven to slide vertically upward, the lower end of the distribution plate 3 moves to be flush with the secondary discharge port 113, so that the larger-particle firecracker paper scraps supported on the distribution plate 3 are discharged from the secondary discharge port 113, completing the discharge of the collected materials in the debris receiving cavity 111. By using the distribution plate 3 initially located at a lower height to increase the capacity of the debris receiving cavity 111 and improve the collection amount of debris in the debris receiving cavity 111, and then only by making the distribution plate 3 slide vertically to discharge the debris when the debris needs to be discharged, the movable distribution plate 3 can be used to improve the crushing efficiency of firecrackers.

[0033] Furthermore, driving cylinders 7 for driving the vertical sliding of the distribution plate 3 are symmetrically arranged in the base frame 1, and the driving cylinders 7 are used to drive the vertical sliding of the distribution plate 3 to improve the sliding stability of the distribution plate 3.

[0034] As a further embodiment provided by the present utility model, a sliding plate 6 is slidably arranged on the distribution plate 3. Through slots 61 aligned with the leakage holes 31 are linearly arrayed on the sliding plate 6. Inner grooves 64 spaced from the through slots 61 are arrayed on the sliding plate 6. Flexible columnar members 8 are arranged in the inner grooves 64. The sliding plate 6 is driven to slide so that the through slots 61 are misaligned with the leakage holes 31, and the flexible columnar members 8 move to extend into the leakage holes 31 from the lower side in the vertical direction.

[0035] Specifically, the sliding plate 6 is slidably arranged in parallel with the distribution plate 3 through a second sliding portion 63 provided on the sliding plate 6. The through slots 61 and the inner grooves 64 are formed on the sliding plate 6. When the distribution plate 3 is at the lowest position, the through slots 61 are aligned with the leakage holes 31 so that the water liquid and smaller-particle debris in the firecracker scraps can fall from the leakage holes 31 into the particle receiving cavity 112. When the distribution plate 3 is driven to slide vertically upward until the lower end is flush with the secondary discharge port 113, the sliding plate 6 slides so that the inner grooves 64 move to be aligned with the leakage holes 31. At this time, the flexible columnar members 8 in the inner grooves 64 are inserted into the leakage holes 31 from the lower side of the leakage holes 31. First, it is to prevent some debris from being pressed into the particle receiving cavity 112 through the leakage holes 31 when the debris on the distribution plate 3 rolls and is discharged from the secondary discharge port 113, improving the stability of the classified collection of firecracker scraps. Secondly, the flexible columnar members 8 are inserted into the leakage holes 31 from the lower side of the leakage holes 31 to push the debris that may be stuck in the leakage holes 31 upward, thereby avoiding the problem that the small-particle scraps are difficult to fall due to the blockage of the leakage holes 31 and improving the stable separation of the firecracker scraps.

[0036] As a further embodiment provided by the present utility model, sliding columns 62 are symmetrically arranged on the sliding plate 6, and inclined sliding grooves 13 are symmetrically formed in the receiving groove 11. The sliding columns 62 are slidably arranged in the sliding grooves 13, and the material distribution plate 3 is driven to slide vertically close to the secondary discharge port 113 to drive the sliding plate 6 to slide.

[0037] Specifically, as Figure 3 shown, sliding columns 62 are symmetrically arranged on the sliding plate 6, and inclined sliding grooves 13 are symmetrically formed in the receiving groove 11. The sliding columns 62 are slidably arranged in the sliding grooves 13. When the material distribution plate 3 is driven to slide vertically close to the secondary discharge port 113, the sliding plate 6 moves vertically with the material distribution plate 3, causing the sliding columns 62 to slide in the sliding grooves 13. Therefore, the sliding columns 62 drive the sliding plate 6 to slide under the reaction force of the sliding grooves 13, and the sliding columns 62 and the sliding grooves 13 are used to drive the sliding plate 6 to move synchronously with the material distribution plate 3, simplifying the structure and improving the operation stability.

[0038] As a further embodiment provided by the present utility model, scraping tips 611 are arranged in the through groove 61, and the sliding plate 6 is driven to slide so that the scraping tips 611 move to scrape the lower port of the vertical direction of the material leakage hole 31.

[0039] Specifically, as Figure 4 shown, scraping tips 611 are arranged in the through groove 61. During the destruction process, firecracker debris continuously falls on the material distribution plate 3, and some large particle debris on the material distribution plate 3 will inevitably enter the material leakage hole 31 under pressure and cause blockage. When the material distribution plate 3 is driven to slide vertically upward, the sliding plate 6 is driven to slide so that the scraping tips 611 move to scrape the lower port of the vertical direction of the material leakage hole 31. Then, the scraping tips 611 are used to pull out the large particle debris in the severely blocked material leakage hole 31 downward and drop it into the particle receiving cavity 112, thereby using the scraping tips 611 and the flexible column member 8 to dredge the severely blocked material leakage hole 31 in two directions and improving the separation stability of the firecracker debris.

[0040] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
