Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a grain plane rotary screen machine, including feeder hopper 1, connect at the sieve box 2 of feeder hopper 1 bottom department, set up the dust absorption subassembly 3 in feeder hopper 1 lateral wall department.

Referring to fig. 2-3, the suction assembly 3 includes a first opening 31, a suction fan 32, a connector 33, and a screen 34. The first opening 31 is arranged at the side wall of the feed hopper 1 and has a circular vertical section; the exhaust fan 32 is cylindrical, and the exhaust fan 32 is covered at the first opening 31 and is arranged at an interval with the feed hopper 1; connecting piece 33 sets up three and all connects between feeder hopper 1 and air exhauster 32, and connecting piece 33 all connects between feeder hopper 1 and air exhauster 32 for the Z shape, all is provided with connecting piece 33 between the lateral wall of air exhauster 32 both sides, the lateral wall of bottom and feeder hopper 1, and connecting piece 33 is close to one side and air exhauster 32 fixed connection of air exhauster 32, and the opposite side is connected with the lateral wall of air exhauster 32 through the first bolt 331 of level setting. The filter screen 34 is placed in a cavity formed between the three connecting pieces 33, the filter screen 34 is connected between the suction fan 32 and the feed hopper 1 in a clamping mode, and the filter screen 34 is arranged to mainly reduce the probability of the situation that grains are sucked into the suction fan 32.

Referring to fig. 2, in order to filter the dust drawn by the suction fan 32, a circular tube 321 is disposed at a side of the suction fan 32 away from the feeding hopper 1, and a non-woven fabric dust bag 322 is fixedly connected to an end of the circular tube 321 away from the suction fan 32.

Referring to fig. 3, in order to make the sealing between the filter screen 34 and the dust hopper better, a groove 341 is formed in the side wall of the filter screen 34 opposite to the feeding hopper 1, and a rubber ring 342 is connected to the inside of the groove 341.

Referring to fig. 4, in order to easily take out the strainer 34 from between the suction fan 32 and the hopper 1 by hand, a handle 35 is fixedly connected to an upper end surface of the strainer 34.

Referring to fig. 4, in order to make the filter screen 34 stably placed between the suction fan 32 and the feeding hopper 1, a square plate 36 covering the top of the suction fan 32 is connected to the upper end surface of the filter screen 34, and a second bolt 361 screwed to the top of the suction fan 32 is vertically inserted into the square plate 36.

Referring to fig. 5, in the using process, the dust drawn by the suction fan 32 is limited, and some dust is located at one side away from the suction fan 32, so that the effect of removing the dust is poor, so that a second opening 37 (shown in fig. 2) is opened at one side of the feeding hopper 1 away from the suction fan 32, a blower 38 is covered at the second opening 37, a circular ring 381 is connected at the side wall of the blower 38, and the circular ring 381 is connected with the side wall of the feeding hopper 1 through a fourth bolt 382.

Referring to fig. 5, as the blower 38 is provided, during the blowing process of the blower 38, the blower 38 blows indoor air into the feeding hopper 1, and if the indoor air is large in dust content, the indoor dust is easily blown into the feeding hopper 1, so as to cause secondary pollution, a first placing ring 39, a gauze 391 and a second placing ring 392 are sequentially arranged on one side of the blower 38 away from the feeding hopper 1, and four third bolts 393 horizontally passing through the second placing ring 392, the gauze 391 and the first placing ring 39 are arranged on the second placing ring 392.

When the dust-removing device is used, raw materials enter from the feeding hopper 1, the air in the feeding hopper 1 is sucked out by the exhaust fan 32, the screen box body 2 is in an incomplete sealing state, the blower 38 blows air to the raw materials in the feeding hopper 1, the air is blown into one side of the exhaust fan 32 by the blower 38 due to the fact that the dust is light in weight, the exhaust fan 32 synchronously performs air suction, and the dust can penetrate through the filter screen 34 from the inside of the feeding hopper 1 and then enters the inside of the non-woven fabric dust collecting bag 322.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
