DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to solve the problem that the existing technology cannot effectively sort the waste according to its weight, the following technical solution is provided. Figure 1-2 ;

[0021] A gravity sorting machine for efficiently sorting waste materials and domestic garbage comprises a mounting frame 1, a feed box 2 is arranged on the top of the mounting frame 1, a feed port 21 is arranged on the top of the feed box 2, a discharge port 22 is arranged on one side of the bottom of the feed box 2, materials enter the feed box 2 through the feed port 21, and fall onto the surface of a vibrating screen 3 from the discharge port 22; a vibrating screen 3 and a bellows 4 are arranged inside the mounting frame 1, the vibrating screen 3 is made of metal, the vibrating screen 3 is located directly below the discharge port 22, the bellows 4 is arranged directly below the vibrating screen 3, an air outlet of the bellows 4 is located on the top thereof and faces the vibrating screen 3, a light material discharge plate 5 is arranged on one side of the top surface of the vibrating screen 3, and a heavy material discharge plate 6 is arranged on the side of the bottom surface of the vibrating screen 3 away from the light material discharge plate 5.

[0022] A fan is arranged inside the bellows 4, and a fan shaft 41 is arranged on the fan to drive the fan to rotate, and the fan shaft 41 is connected to a second motor 42 on one side of the mounting frame 1. The vibrating screen 3 is inclined toward one side of the light material discharging plate 5, and the light material discharging plate 5 and the vibrating screen 3 have the same inclination angle and inclination direction, so that the light material can slide off the light material discharging plate 5; the three sides of the vibrating screen 3 away from the light material discharging plate 5 are all provided with a second baffle 33 to prevent the material on the surface of the vibrating screen 3 from falling from the side; the higher side of the vibrating screen 3 is provided with an air duct 32, and the air inlet end of the air duct 32 is connected to the top of the bellows 4, and the air outlet end penetrates the second baffle 33 and faces the top of the vibrating screen 3.

[0023] Specifically, the second motor 42 drives the fan shaft 41 to rotate, and the fan shaft 41 makes the fan inside the bellows 4 run and makes the fan blow out vertical wind force, which blows up the lighter materials on the surface of the vibrating screen 3 through the sieve holes, and a part of the wind force also reaches the upper top surface of the vibrating screen 3 through the air duct 32, and blows the lighter materials horizontally from the higher side of the vibrating screen 3, so that it is blown down to the light material discharge plate 5, and finally slides down to the light material collection area along the light material discharge plate 5. The heavier materials are difficult to be blown up by the wind, so they stay on the surface of the vibrating screen 3, fall below the vibrating screen 3 with the vibration, and slide down to the heavy material collection area through the heavy material discharge plate 6.

[0024] The discharge port 22 is arranged at an angle, and a first baffle 7 is arranged obliquely above the discharge port 22. The first baffle 7 is directly opposite to the position of the discharge port 22, and the first baffle 7 is connected to the mounting frame 1 through a first telescopic adjustment rod 71; the discharge amount can be controlled and adjusted by the setting of the first baffle 7. When the discharge amount is too much, the first telescopic adjustment rod 71 extends, driving the first baffle 7 to move toward the position of the discharge port 22, thereby blocking a part of the space of the discharge port 22, thereby controlling the discharge amount, making it easier for the vibrating screen 3 to fully screen the material on its surface.

[0025] Four second telescopic adjustment rods 31 are symmetrically provided on both sides of the vibrating screen 3. The bottom end of the second telescopic adjustment rod 31 is connected to the vibrating screen 3, and the top end is rotatably connected to the eccentric shaft 8. The eccentric shaft 8 is transmission-connected to the first motor 81 provided on one side of the mounting frame 1. The relative height of the vibrating screen 3 can be adjusted by telescoping the second telescopic adjustment rod 31, so as to adjust the distance between the vibrating screen 3 and the discharge port 22 according to different material volumes; the first motor 81 drives the eccentric shaft 8 to rotate, and the eccentric shaft 8 drives the vibrating screen 3 to fluctuate up and down through the second telescopic adjustment rod 31 to generate vibration, so that the material on the vibrating screen 3 is easier to disperse for sorting.

[0026] Working principle: the material enters the feed box 2 through the feed port 21 and falls onto the surface of the vibrating screen 3 from the discharge port 22. The first motor 81 drives the eccentric shaft 8 to rotate, and the eccentric shaft 8 drives the vibrating screen 3 to fluctuate up and down through the second telescopic adjustment rod 31 to generate vibration, so that the material on the vibrating screen 3 is easier to disperse for sorting; the second motor 42 drives the fan shaft 41 to rotate, and the fan shaft 41 rotates the fan inside the bellows 4 and generates vertical upward wind force, which blows up the lighter materials on the surface through the sieve holes of the vibrating screen 3, and part of the wind force also reaches the upper top surface of the vibrating screen 3 through the air duct 32, and blows the light materials horizontally from the higher side of the vibrating screen 3, so that it is blown onto the light material discharge plate 5 and slides down to the light material collection area along the light material discharge plate 5; the heavier materials are difficult to be blown up by the wind, so they stay on the surface of the vibrating screen 3, fall to the bottom of the vibrating screen 3 with the vibration, and slide to the heavy material collection area through the heavy material discharge plate 6, thereby completing the sorting of light materials and heavy materials.
