A fixed plate 3 is fixedly installed on one side of the crushing box 5, and the motor 2 is fixedly installed on the fixed plate 3. A symmetrically arranged transmission shaft 17 and a transmission shaft 2 are rotatably installed in the crushing box 5, one end of the transmission shaft 17 passes through the crushing box 5 and is fixedly installed with the output end of the motor 2, and a crushing roller 8 is fixedly sleeved on the transmission shaft 17 and the transmission shaft 2. The end of the transmission shaft 17 away from the motor 2 passes through the crushing box 5 and is fixedly sleeved with a gear 16, and the end of the transmission shaft 2 away from the motor 2 passes through the crushing box 5 and is fixedly sleeved with a gear 2, and the gear 2 is meshed with the gear 16.

[0020] The upper surface of the crushing box 5 is provided with a feed port 1 connected to the interior thereof. The feed port 1 is located above the crushing rollers 8, so that the solid waste can be directly poured between the two crushing rollers 8, which is beneficial to crushing the solid waste.

[0021] A discharge port 9 is fixedly installed in the crushing box 5. The discharge port 9 is located below the two crushing rollers 8. The discharge port 9 is funnel-shaped for easy feeding. A magnet 11 is fixedly installed in the crushing box 5. The magnet 11 is arranged horizontally and has a semicircular cross section. A hollow shaft 10 is rotatably sleeved on the magnet 11. The hollow shaft 10 is located directly below the discharge port 9. A motor 3 14 is fixedly installed on one side of the crushing box 5. The output end of the motor 3 14 passes through the crushing box 5 and is fixedly mounted with the hollow shaft 10.

[0022] A motor 2 4 is fixedly installed on one side of the crushing box 5, and a transmission shaft 3 6 is fixedly installed on the output end of the motor 2 4 through the crushing box 5. A fan blade 7 is fixedly installed on one end of the transmission shaft 3 6, and the fan blade 7 corresponds to the position of the hollow shaft 10. A collection box 12 and a collection box 2 13 are slidably installed at the bottom of the crushing box 5. The collection box 12 is located directly below the hollow shaft 10, and the collection box 2 13 is located on the side of the collection box 12 away from the fan blade 7. An opening and closing door 15 is installed on one side of the bottom of the crushing box 5. Opening the opening and closing door 15 facilitates taking out the collection box 12 and the collection box 2 13.

[0023] The working principle of a solid waste treatment device for environmental protection engineering provided by the utility model is as follows:

[0024] When in use, solid waste is put into the feed port 1, and motor 1 2, motor 2 4, and motor 3 14 are started at the same time. Motor 1 2 drives transmission shaft 1 17 to rotate, transmission shaft 1 17 drives gear 1 16 to rotate, gear 1 16 drives gear 2 to rotate, and gear 2 drives transmission shaft 2 to rotate, so that transmission shaft 1 17 and transmission shaft 2 respectively drive corresponding crushing rollers 8 to rotate, and the two crushing rollers 8 rotate to crush the waste.

[0025] The crushed waste falls onto the hollow shaft 10 through the discharge port 9, and the metal debris in the waste will be adsorbed by the magnet 11 to the top of the hollow shaft 10. The motor 2 4 drives the fan blade 7 to rotate through the transmission shaft 3 6, and the fan blade 7 blows the non-metallic impurities into the collection box 2 13. The motor 3 14 drives the hollow shaft 10 to rotate. When the metal debris above the hollow shaft 10 rotates with the hollow shaft 10, since the magnet 11 is a semi-cylinder divided along the axis of the cylinder, when the metal debris adsorbed on the top of the hollow shaft 10 rotates to the bottom of the hollow shaft 10, the metal debris is affected by the magnetic force of the magnet 11, which becomes smaller and falls into the collection box 1 12, so that the metal debris will not wrap the hollow shaft 10 and will not affect the suction force of the magnet 11 on the metal debris.

[0026] When cleaning the debris, the opening and closing door 15 is opened to facilitate pulling out the collection box 12 and the collection box 2 13 for cleaning.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
