[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 , the utility model provides a technical solution:

[0023] A dust removal jaw crusher includes a shell 1, support legs 2 are fixedly installed at the four corners of the lower end face of the shell 1, a feed port 3 is connected to the upper end face of the shell 1, and the feed port 3 is connected to the existing crusher, a discharge port 5 is opened on the lower end face of the shell 1, a sieve plate 6 is slidably connected inside the shell 1, a motor 7 is provided on the front side of the shell 1, a support rod 8 is fixedly installed between the motor 7 and the shell 1, a cam 9 is fixedly installed at the end of the output shaft at the rear end of the motor 7, a transmission plate 10 is provided below the cam 9, a support plate 12 is fixedly installed on the front face of the shell 1, a spring 11 is fixedly installed between the support plate 12 and the transmission plate 10, and the transmission plate 10 is fixedly connected to the sieve plate 6.

[0024] A half gear 13 is fixedly mounted on the outer surface of the output shaft of the motor 7 , a support frame 14 is provided on the outer side of the half gear 13 , a slide rail 16 is fixedly mounted on the upper end of the support frame 14 , and the slide rail 16 is slidably connected to the support rod 8 .

[0025] Racks 15 are fixedly mounted on the upper and lower end surfaces of the support frame 14 , and the racks 15 are meshed with the half gears 13 .

[0026] A sleeve 17 is provided on the left side of the front end surface of the housing 1 , and a piston plate 19 is slidably connected to the interior of the sleeve 17 .

[0027] A transmission shaft 18 is fixedly mounted on the left end of the support frame 14 . The transmission shaft 18 extends into the interior of the sleeve 17 and is fixedly connected to the piston plate 19 .

[0028] An output pipe 20 is connected to the input pipe at the left end surface of the sleeve 17 . The output pipe 20 extends into the interior of the housing 1 and is arranged corresponding to the discharge port 5 .

[0029] First, the crushed gravel will enter the interior of the shell 1 through the feed port 3. By starting the motor 7, the cam 9 and the half gear 13 can be rotated synchronously. The cam 9 will continuously hit the transmission plate 10 and cooperate with the spring 11 to make the transmission plate 10 vibrate continuously. The transmission plate 10 will synchronously carry the screen plate 6 to vibrate, which can not only vibrate and screen the gravel, but also raise the dust in the gravel.

[0030] The utility model provides a cam 9 and a spring 11 to vibrate the screen plate 6, thereby vibrating and screening the gravel and stirring up the dust in the gravel, thereby relatively improving the practicability of the equipment.

[0031] The half gear 13 is meshed with the racks 15 on the upper and lower sides of the support frame 14, thereby driving the support frame 14 to reciprocate. The support frame 14 drives the piston plate 19 to reciprocate inside the sleeve 17 through the transmission column. When the piston plate 19 moves to the right, the one-way input valve inside the input pipe is opened, and the external gas is sucked into the interior of the sleeve 17. When the piston plate 19 moves to the left, the one-way output valve inside the output pipe 20 is opened, and the gas inside the sleeve 17 is discharged into the outer casing 1, and the raised dust appears in the discharge trough 4, thereby discharging the dust in the gravel out of the equipment.

[0032] The utility model is provided with a sleeve 17 and a piston plate 19 to suck the outside air and blow the dust inside the housing 1 to the discharge trough 4 and discharge it out of the equipment.

[0033] Working principle: First, the crushed gravel will enter the interior of the shell 1 through the feed port 3. By starting the motor 7, the cam 9 and the half gear 13 can be rotated synchronously. The cam 9 will continuously hit the transmission plate 10, and cooperate with the spring 11 to make the transmission plate 10 vibrate continuously. The transmission plate 10 synchronously carries the screen plate 6 to vibrate, which can not only vibrate and screen the gravel, but also raise the dust in the gravel. The half gear 13 is meshed with the racks 15 on the upper and lower sides of the support frame 14, thereby driving the support frame 14 to reciprocate. The support frame 14 drives the piston plate 19 to reciprocate inside the sleeve 17 through the transmission column. When the piston plate 19 moves to the right, it will open the one-way input valve inside the input pipe and suck the external gas into the interior of the sleeve 17. When the piston plate 19 moves to the left, it will open the one-way output valve inside the output pipe 20, discharge the gas inside the sleeve 17 into the shell 1, and the raised dust will appear in the discharge chute 4, thereby discharging the dust in the gravel out of the equipment.
