Description

Technical Field

[0002] A winnowing machine is a commonly used machine that uses wind force and the deadweight of objects to screen. Ordinary winnowing machines need to winnow along the trajectory of the object, so the object has a long travel distance, which results in a larger size of the winnowing machine and a larger space. Some winnowing machines are installed at high places, and some of the winnowed flakes fall freely and directly onto the planned area on the ground. However, in the process of material falling, due to the influence of its own shape and the air, the landing point will be greatly offset, which is not convenient for sorting and transportation.

[0018] See also Figure 1The utility model structural view, a reciprocating channel flaking air selection device, which includes a main body 3, the main body 3 is a cavity structure, the outer side of the main body 3 is connected to a mounting plate 9, the main body 3 is mounted on a platform 13 through the mounting plate 9, the mounting plate 9 and the main body 3 are welded together, a threaded hole is provided on the end surface of the mounting plate 9, for passing bolts to fix the mounting plate 9, the platform 13 is provided with an opening structure that passes through the upper and lower parts, the end of the main body 3 is connected to a return channel 11, the side of the return channel 11 is provided with a blanking channel 12, and the blanking channel 12 is connected to the return channel 11 and the main body 3, and the side of the return channel 11 is provided with a discharge channel 10, wherein the blanking channel 12 and the discharge channel 10 , and the return channel 11 are both arranged on the inner side of the opening structure, passing through the platform 13 from top to bottom. The upper end of the discharge channel 10 is connected with a feed port 8, and the feed port 8 is connected to an external device feeding elevator or a feeding conveyor for material transportation. The left end of the main body 3 is connected with a bag dust collector 2, and one end of the bag dust collector 2 is connected to a negative pressure fan 1. The negative pressure generated by the negative pressure fan 1 acts on the return channel 11 through the bag dust collector 2. The shavings entering the discharge channel 10 from the feed port 8 are affected by the negative pressure at the end of the return channel 11 when leaving the discharge channel 10. The lighter shavings will move upward along the return channel 11 and enter the interior of the main body 3 along the return channel 11.

[0019] A bracket is connected between the main body 3 and the mounting plate 9. A rectangular skylight is provided at the upper end of the main body 3. An upper cover 4 is provided inside the skylight. The upper cover 4 is rotatably connected to the outer wall of the main body 3 through a hinge. The skylight can be opened when needed.

The shavings extracted by the negative pressure pass through the return channel 11 to the inside of the main body 3. Because of the climbing height, they will gradually lose power and fall along the drop channel 12. Some of the lighter ones will be blocked by the baffle 6 with mesh holes 7, and the fine dust particles will pass through the mesh holes 7 and enter the bag dust collector 2.

The falling shavings fall on the belt conveyor 16 for the next step of transportation.

[0023] The utility model adopts a structure in which the reciprocating channels are fitted together to arrange the discharging channel 10 and the returning channel 11 in a smaller space, thereby reducing the volume of the air separator. At the same time, the vertical fan cabinet 15 and the belt conveyor 16 are used to collect and transport the fallen heavy flakes, thereby realizing the function of reciprocating air duct screening, saving the space occupied by the air duct, and collecting the fallen flakes.
