[0021] Now, with reference to the accompanying drawings and preferred embodiments, the present invention will be further described in detail. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0022] Refer to Figure 1 And Figure 2 As shown, the present invention provides a technical solution: a variable cross-section negative pressure swing hammer crusher, including a variable cross-section swing hammer crusher body 1. The bottom of the variable cross-section swing hammer crusher body 1 is fixedly connected with a bottom plate 2. A motor 3 is installed on the top of the bottom plate 2. A belt pulley 6 is installed on one side of the variable cross-section swing hammer crusher body 1. A first baffle 4 is rotatably connected to the inside of the variable cross-section swing hammer crusher body 1 through a rotating shaft. A stopper 5 is fixedly connected to the inside of the variable cross-section swing hammer crusher body 1. Both sides of the first baffle 4 are fixedly connected with first return springs 7. The other ends of the first return springs 7 are fixedly connected with the inner wall of the variable cross-section swing hammer crusher body 1. An exhaust pipe 21 is installed on one side of the variable cross-section swing hammer crusher body 1. The inside of the exhaust pipe 21 is communicated with the inside of the variable cross-section swing hammer crusher body 1. The user starts the motor 3 to drive the swing hammer inside the variable cross-section swing hammer crusher body 1 to rotate. The object to be crushed is put into the inside of the variable cross-section swing hammer crusher body 1 through the inlet at the top of the variable cross-section swing hammer crusher body 1. The object is crushed by the swing hammer. The air inside the variable cross-section swing hammer crusher body 1 is pumped out through the exhaust pipe 21, so that a negative pressure is formed inside the variable cross-section swing hammer crusher body 1. The dust is sucked away through the exhaust pipe 21. By installing the first baffle 4 at the inlet of the variable cross-section swing hammer crusher body 1, the broken blocks can be blocked. During the rotation of the first baffle 4, the stopper 5 limits the rotation of the first baffle 4 to prevent the broken blocks from splashing and causing harm to the nearby staff during the crushing process.

[0023] Refer to Figure 4 And Figure 5As shown in the figure, in this implementation: a first through groove 18 is provided at the bottom of one side of the variable cross-section swing hammer crusher body 1, and a collection box 8 is slidably connected inside the first through groove 18. By installing the first through groove 18 at the bottom of the variable cross-section swing hammer crusher body 1, the crushed blocks after crushing can be collected, facilitating the centralized treatment of the crushed blocks.

[0024] Referring to Figure 4 As shown in the figure, in this implementation: a storage groove 9 is provided at the top of the collection box 8, and a limiting inclined block 10 is slidably connected inside the storage groove 9. One side of the limiting inclined block 10 is fixedly connected with a handle 20. When the user needs to take out the collection box 8, by pressing the handle 20, the limiting inclined block 10 moves downward and retracts into the storage groove 9, releasing the limit on the collection box 8, so that the collection box 8 can be pulled outwards. By limiting the collection box 8, it is possible to prevent the impact generated when the crushed blocks fall from causing the collection box 8 to displace.

[0025] Referring to Figure 4 As shown in the figure, in this implementation: limiting sliding grooves 11 are provided on both sides inside the storage groove 9, and limiting sliding blocks 12 are fixedly connected to both sides of the limiting inclined block 10. When the user moves the handle 20 to drive the limiting inclined block 10 to move up and down, the limiting sliding blocks 12 on both sides of the limiting inclined block 10 move inside the limiting sliding grooves 11, assisting the movement of the limiting inclined block 10 and preventing the limiting inclined block 10 from tilting during the movement.

[0026] Referring to Figure 4 As shown in the figure, in this implementation: two thrust springs 13 are fixedly connected to the bottom of the limiting inclined block 10, and the bottom of the thrust springs 13 is fixedly connected to the bottom inside the storage groove 9. When the user installs the collection box 8 inside the first through groove 18, by aligning the collection box 8 with the position of the first through groove 18 and pushing it inwards, when the limiting inclined block 10 contacts the outer wall of the variable cross-section swing hammer crusher body 1, the limiting inclined block 10 is squeezed and retracts into the storage groove 9. When the limiting inclined block 10 moves inside the variable cross-section swing hammer crusher body 1, the extrusion on the limiting inclined block 10 is released, and under the thrust of the thrust springs 13, the limiting inclined block 10 is pushed upwards to limit the collection box 8.

[0027] Referring to Figure 3 And Figure 5As shown in the figure, in this embodiment: a sieve plate 14 is installed inside the variable cross-section swing hammer crusher body 1. The sieve plate 14 is a slope and is located above the collection box 8. A second through groove 19 is provided on one side of the variable cross-section swing hammer crusher body 1. By installing the sieve plate 14 above the collection box 8, large-sized fragments can be filtered. After the large-sized fragments fall onto the sieve plate 14, they slide out from the second through groove 19, avoiding the situation that during the process of object crushing, due to different materials of the objects, some fragments are relatively large and need secondary crushing. By installing the sieve plate 14 for screening, it is not necessary to manually sort the fragments.

[0028] Refer to Figure 1 As shown in the figure, in this embodiment: four connecting rods 15 are fixedly connected to one side of the variable cross-section swing hammer crusher body 1. A second baffle 16 is slidably connected to the surface of the connecting rod 15. Four second return springs 17 are fixedly connected to one side of the second baffle 16. The other ends of the second return springs 17 are fixedly connected to one side of the connecting rod 15. By installing the second baffle 16 at the position of the second through groove 19, the sliding speed of the fragments screened by the sieve plate 14 can be buffered, preventing the fragments from flying out of the second through groove 19 and causing harm to the staff.

[0029] Working principle: The user starts the motor 3 to drive the hammers inside the variable cross-section hammer crusher body 1 to rotate. The object to be crushed is put into the inside of the variable cross-section hammer crusher body 1 through the inlet at the top of the variable cross-section hammer crusher body 1. The object is crushed by the hammers, and the dust is sucked into the inside of the air extraction pipe 21. By installing the first baffle 4 at the inlet of the variable cross-section hammer crusher body 1, the broken blocks can be blocked to prevent the broken blocks from splashing and hurting the nearby workers during the crushing process. By installing the first through groove 18 at the bottom of the variable cross-section hammer crusher body 1, the broken blocks after crushing can be collected, which is convenient for centralized treatment of the broken blocks. When the collection box 8 needs to be taken out, by pressing the handle 20, the limit inclined block 10 moves downward and retracts into the storage groove 9, releasing the limit on the collection box 8, so that the collection box 8 can be pulled outwards. By limiting the collection box 8, it can prevent the impact generated when the broken blocks fall from causing the displacement of the collection box 8. During the process of moving the handle 20 to drive the limit inclined block 10 to move up and down, the limit sliding blocks 12 on both sides of the limit inclined block 10 move inside the limit sliding groove 11 to assist the movement of the limit inclined block 10 and prevent the limit inclined block 10 from tilting during the movement. When installing the collection box 8 into the inside of the first through groove 18, by aligning the collection box 8 with the position of the first through groove 18 and pushing it inwards, when the limit inclined block 10 contacts the outer wall of the variable cross-section hammer crusher body 1, the limit inclined block 10 is squeezed and retracts into the storage groove 9. When the limit inclined block 10 moves into the inside of the variable cross-section hammer crusher body 1, the extrusion on the limit inclined block 10 is released, and under the thrust of the thrust spring 13, the limit inclined block 10 is pushed upwards to limit the collection box 8. By installing the sieve plate 14 above the collection box 8, the larger broken blocks can be filtered. After the larger broken blocks fall onto the sieve plate 14, they slide out from the second through groove 19, avoiding that during the process of crushing the object, due to different materials of the object, some broken blocks are larger in volume and need secondary crushing. By installing the sieve plate 14 for screening, by installing the second baffle 16 at the position of the second through groove 19, the sliding speed of the broken blocks screened by the sieve plate 14 can be buffered to prevent the broken blocks from flying out of the second through groove 19 and hurting the workers.
