[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] Reference Figure 1-Figure 6 The present invention provides a hammer crusher, comprising:

[0059] The box body 1 is provided with a feed pipe 2 at one end, a sealing plate 3 is rotatably connected to the feed pipe 2, and a transmission mechanism is provided on the sealing plate 3;

[0060] The dust hood 4 is arranged at the inner top wall of the box body 1 near the feed pipe 2. The dust hood 4 is connected with a pair of dust guide pipes 5. One end of the dust guide pipe 5 away from the dust hood 4 is connected with the bottom of the inner cavity of the box body 1. The dust guide pipe 5 is provided with a negative pressure adsorption mechanism and an atomizing spray mechanism. The atomizing spray mechanism is located above the negative pressure adsorption mechanism. The negative pressure adsorption mechanism and the atomizing spray mechanism are both connected to the transmission mechanism. When the sealing plate 3 is turned over, the negative pressure adsorption mechanism is driven to rotate through the transmission mechanism, so that the dust in the box body 1 enters the dust guide pipe 5. When the sealing plate 3 is reset, the atomizing spray mechanism is driven by the transmission mechanism to spray atomized water into the dust guide pipe 5.

[0061] The motor 6 is arranged at one side of the box body 1. The output end of the motor 6 is connected to a rotating shaft 7. The rotating shaft 7 extends into the box body and is detachably connected to a plurality of assembly plates 8. The assembly plates 8 are used to install hammer heads.

[0062] By arranging a rotatable sealing plate 3 in the feed pipe 2, the feed pipe 2 can be closed to prevent dust floating in the box body 1 from flowing out through the feed pipe 2 during crushing. In addition, when adding material, it is necessary to flip the sealing plate 3 first, so that when the sealing plate 3 moves, the negative pressure adsorption mechanism is driven to rotate through the transmission mechanism, so that the dust in the box body 1 enters the dust guide pipe 5, reducing the probability of dust escaping through the feed pipe 2. Conversely, when the sealing plate 3 is reset, the atomizing spray mechanism is driven by the transmission mechanism to spray atomized water into the dust guide pipe 5, so that the dust in the dust guide pipe 5 is attached to the water and then flows into the box body 1 from the bottom end of the dust guide pipe 5, thereby effectively reducing the amount of dust escaping during the use of the hammer crusher, effectively suppressing the problem of dust, and improving the cleanliness of the processing environment.

[0063] Furthermore, the water vapor atomization technology atomizes water into fine water droplets, which quickly diffuse in the air and collide with the suspended dust particles to form larger particle clusters, thereby effectively reducing the dust concentration in the air. Due to the high distribution density of the water mist, the relative movement speed of the dust and the water droplets increases, which is conducive to the wetting of the dust by water, but does not make the material itself wet, thereby preventing the crushed material in the box 1 from becoming sticky.

[0064] In one embodiment of the present invention, the transmission mechanism includes a first connecting rod 9, one end of which is hinged to the sealing plate 3; a second connecting rod 10 is hinged to the end of the first connecting rod 9 away from the sealing plate 3, and the end of the second connecting rod 10 away from the first connecting rod 9 extends out of the feeding tube 2 through a guide hole provided on the feeding tube 2 and is fixedly connected with a first rack 11 and a second rack 12, the first rack 11 is transmission-connected to the two negative pressure adsorption mechanisms through a first ratchet mechanism, and the second rack 12 is transmission-connected to the two atomizing spray mechanisms through a second ratchet mechanism. A sealing ring is provided at the guide hole to improve the sealing performance. The negative pressure adsorption mechanism includes: a mounting cover 13 is fixedly connected to the side wall of the dust guide tube 5; a filter plate 14 is fixedly connected to the end of the mounting cover 13 close to the dust guide tube 5; a fan 15 is rotatably connected to the mounting cover 13, the fan 15 is located on the side of the filter plate 14 away from the dust guide tube 5, and the shaft of the fan 15 is fixedly connected to the first gear 16, and the first gear 16 and the first rack 11 are transmission-connected through the first ratchet mechanism. The first ratchet mechanism includes: a first rotating rod 17 rotatably connected to the outer top wall of the box body 1; a first one-way ratchet 18 is fixedly mounted on the first rotating rod 17, and a first toothed ring 19 is provided on the first one-way ratchet 18, and the first toothed ring 19 is meshed with the first rack 11; a pair of second gears 20 are fixedly connected to the first rotating rod 17, and the pair of second gears 20 correspond one-to-one to and mesh with the pair of first gears 16.

[0065] When the closing plate 3 is opened, the second connecting rod 10 is pushed by the first connecting rod 9 to move along the guide through hole, thereby driving the first rack 11 to push the first gear ring 19 to make the first one-way ratchet 18 rotate, and then the first rotating rod 17 is driven to rotate by the first one-way ratchet 18, and the first rotating rod 17 drives a pair of second gears 20 to rotate, and then the second gear 20 drives the first gear 16 to rotate, so that the first gear 16 drives the fan 15 to rotate, and the rotation of the fan 15 generates a negative pressure adsorption force in the dust guide pipe 5, so that the dust near the feed pipe 2 is adsorbed into the dust guide pipe 5 through the dust hood 4, conversely, when the closing plate 3 is reset, the second connecting rod 10 drives the first rack 11 to reset, at this time, the first rotating rod 17 can be kept stationary by the first one-way ratchet 18, thereby preventing the fan 15 from rotating.

[0066] In one embodiment of the present invention, the atomizing spray mechanism includes a main pipeline 21; an opening and closing plate 22 is rotatably arranged in the main pipeline 21, and the opening and closing plate 22 is connected to the second rack 12 through a second ratchet mechanism; a plurality of auxiliary pipelines 23 are fixedly installed on the dust guide pipe 5, and the plurality of auxiliary pipelines 23 are connected to the main pipeline 21, and the auxiliary pipelines 23 extend into the dust guide pipe 5 and are connected to a plurality of atomizing nozzles 24.

[0067] When the sealing plate 3 flips, the second connecting rod 10 is pushed by the first connecting rod 9 to move along the guide through hole, thereby driving the second rack 12 to move along the second one-way ratchet 26. At this time, the second gear ring 27 keeps idling on the second one-way ratchet 26, so that the opening and closing plate 22 is fixed to block the main pipe 21, so as to avoid affecting the adsorption efficiency of the fan 15. Conversely, when the second gear 12 is reset, the second rack 12 pushes the second gear ring 27 and the second one-way ratchet 26 to rotate, so that the second rotating rod 25 drives the opening and closing plate 22 to rotate in the main pipe 21 through the universal shaft 28 and the connecting rod 29, so that water flows through the main pipe 21 to multiple auxiliary pipes 23, and is sprayed out after being atomized by the atomizing nozzle 24.

[0068] Furthermore, the main pipe 21 is connected to an external water source via a water pump.
