[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0024] The utility model provides a technical solution: Figure 2 and Figure 3As shown, in this embodiment, a cage crusher for low-noise fertilizer production includes a base plate 1, a sound insulation component 6 is installed on the top of the base plate 1, and the sound insulation component 6 includes two first limiting grooves 601 opened on the top outer wall of the base plate 1, and a rack 602 is slidably connected inside the two first limiting grooves 601 respectively, and a sound insulation cover 604 is fixedly connected to the ends of the two racks 602 away from each other. The two sound insulation covers 604 can overlap with each other to form a closed space, and a crusher body 2 is fixedly installed on the top outer wall of the base plate 1, and the two sound insulation covers 604 can completely wrap the crusher body 2.
[0025] A gear 603 is rotatably connected to the middle of the top outer wall of the base plate 1, and both racks 602 are engaged with the gear 603. A cylinder 605 is fixedly installed on the top outer wall of the base plate 1, and the output end of the cylinder 605 is fixedly connected to the inner wall of one of the sound insulation covers 604.
[0026] Start the cylinder 605 on the top of the base plate 1, and the cylinder 605 drives a sound insulation cover 604 to move to one side. The sound insulation cover 604 drives the rack 602 connected to it to slide along the first limit groove 601. This rack 602 drives the gear 603 to rotate through engagement. The gear 603 can drive the other rack 602 to slide in the opposite direction through engagement, and then the other sound insulation cover 604 will also move in the opposite direction until the two sound insulation covers 604 are merged. The crusher body 2 will be completely wrapped, thereby ensuring that the noise generated by the crusher body 2 will not be transmitted outward at will.
[0027] like Figure 1 As shown, a feed port 3 is provided on the top outer wall of one of the sound insulation covers 604. The feed port 3 can correspond to the position of the feed pipe of the crusher body 2, and the feed port 3 is arranged in a corrugated shape as a whole.
[0028] Workers can feed materials into the crusher body 2 through the feed port 3. The noise generated by the crusher body 2 will be weakened by multiple refractions when passing through the feed port 3, and will also be absorbed by the feed port 3, thereby greatly weakening the conduction of the noise.
[0029] like Figure 2 and Figure 3 As shown, a second limiting groove 606 is provided at both ends of the top outer wall of the base plate 1, and an extension block 607 is provided on the inner wall at both ends of the two sound insulation covers 604. The four extension blocks 607 are respectively slidably connected to the inside of the two second limiting grooves 606. Under the restriction of the second limiting grooves 606, the movement of the sound insulation cover 604 can be ensured to be sufficiently stable.
[0030] like Figure 1 and Figure 2As shown, two rollers 4 are provided on the outer walls of the two sound insulation covers 604 that are away from each other. The four rollers 4 are in contact with the ground, which can support the sound insulation covers 604 without affecting the normal movement of the sound insulation covers 604.
[0031] like Figure 1 and Figure 2 As shown, a baffle 5 is provided on the outside of one of the sound insulation covers 604 , and the baffle 5 can cover the outside of the other sound insulation cover 604 , thereby preventing noise from being transmitted outward from the gap between the two sound insulation covers 604 .
[0032] like Figure 4 As shown, the bottom plate 1, the feed port 3 and the two sound insulation covers 604 include a sound insulation board 6041 and a sound insulation felt 6042, and the sound insulation felt 6042 is in the inner position. The noise generated during the operation of the device will first be absorbed by the sound insulation felt 6042 and then blocked by the sound insulation board 6041. The cooperation of the two can greatly increase the sound insulation effect.
[0033] The utility model provides a low-noise cage crusher for fertilizer production. The specific working principle is as follows:
[0034] When the device is working, the material receiving piece is first placed at the bottom of the discharge port of the crusher body 2, and then the cylinder 605 on the top of the bottom plate 1 is started. The cylinder 605 drives a sound insulation cover 604 to move to one side, and the sound insulation cover 604 drives the rack 602 connected to it to slide along the first limit groove 601. This rack 602 drives the gear 603 to rotate through engagement, and the gear 603 can drive the other rack 602 to slide in the opposite direction through engagement, and then the other sound insulation cover 604 will also move in the opposite direction until the two sound insulation covers 604 are merged together. The crusher body 2 will be completely wrapped, thereby ensuring that the noise generated by the crusher body 2 will not be transmitted outward at will. During this period, the staff can feed the crusher body 2 through the feed port 3, and the noise generated by the crusher body 2 will be weakened by multiple refractions when passing through the feed port 3, and will also be absorbed by the feed port 3, so the conduction of the noise can be greatly weakened.
[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
