Description

Zhongtong electric agricultural windmill

technical field

The utility model relates to a middle-pass type electric agricultural windmill.

Background technique

At present, the windmills used in rural areas to select grains such as rice and wheat have been gradually replaced by electric ones, and the problem of labor-intensive work in the past has been solved. However, both manual windmills and electric windmills currently used are windmills with one end open and the other closed. These windmills have structures such as bellows and blades, which not only occupy the volume of the windmill, but also increase the load on the windmill, making it difficult to move. . Simultaneously, because the electric windmill that uses now is that motor is directly contained on the windmill, neither is easy to repair, maintain, and is equally heavy and inconvenient to operate. Therefore existing windmill is not convenient enough yet, needs improvement. In addition, because the shape design of the genuine product hopper and the grain product hopper in the current bellows also has great defects, the authenticity rate of this kind of crops that rely on gravity and wind for screening is very low, and the screening efficiency is also very low, which cannot meet the requirements of different crops. The screening of crops can only be used by a single machine.

Contents of the invention

The purpose of the utility model is to provide a middle-pass type electric agricultural windmill, which has the advantages of high screening efficiency, light and handy structure, convenient movement and simple operation.

The utility model is realized in this way, it comprises blower fan, wind power adjustment knob, feed hopper, feed control board, bellows, slag chip outlet, waste product discharge hopper, waste product outlet, genuine product discharge hopper, genuine product export and frame , which is characterized in that the lower part of the bellows is connected with the frame, the left end of the bellows is provided with a fan, the fan is connected with a wind adjustment knob, the right end of the bellows is connected with a slag outlet, and the middle part of the upper surface of the bellows is provided with a feeding hopper. The lower end is connected with a feed control panel, the lower surface of the bellows located directly below the feed hopper is connected with a genuine product discharge hopper, and the lower surface of the bellows next to the genuine product discharge hopper is also connected with a waste product discharge hopper, and the genuine product discharge hopper and the waste product discharge hopper are respectively A genuine product outlet and a waste product outlet are provided; the cross-sectional area of the slag chip outlet is smaller than the cross-sectional area of the bellows; the cross-sections of the genuine product discharge hopper and the waste product discharge hopper are the same, and they are all inverted right-angled trapezoidal structures. Wherein the right-angle sides of two upside-down right-angled trapezoids are adjacent.

The technical effects of the utility model are: 1. The windmill adopts the structure of Zhongtong, which saves the traditional bellows, wind blades, and rotating devices, which well reduces the weight of the windmill and is easy to move; 2. The windmill can be used for activities The wind source, while inheriting the labor-saving advantages of the past electric windmill, also has a more convenient movable wind source device, which is easy to operate. 3. This windmill simplifies the structure, improves the mechanical efficiency, reduces the space occupied by the device, saves labor, is safe and practical, and has a good market; 4. The structure of this windmill is more reasonable and compact, which improves the screening efficiency and finished products rate, easy to operate and use.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, the utility model is realized in this way, it comprises blower fan 1, wind force adjustment knob 2, feed hopper 3, feed control board 4, bellows 5, slag chip outlet 6, Dust product discharge hopper 7, waste product outlet 8, genuine product discharge hopper 9, genuine product outlet 10 and frame 11, its structural feature is that bellows 5 bottoms are connected with frame 11, and the left end of bellows 5 is provided with fan 1, and fan 1 is connected There is a wind adjustment knob 2, the right end of the bellows 5 is connected with a slag outlet 6, the middle part of the upper surface of the bellows 5 is provided with a feed hopper 3, and the lower end of the feed hopper 3 is connected with a feed control panel 4, which is located at the front of the feed hopper 3. The lower surface of bellows 5 below is connected with genuine product discharge hopper 9, and the lower surface of bellows 5 next to genuine product discharge hopper 9 is also connected with chaff product discharge hopper 7, and authentic product discharge hopper 9 and chaff product discharge hopper 7 are respectively provided with genuine product outlet 10 and The waste product outlet 8; the cross-sectional area of the slag chip outlet 6 is less than the cross-sectional area of the bellows 5; the cross-sections of the genuine product discharge hopper 9 and the waste product discharge hopper 7 are the same, and are inverted right-angled trapezoidal structures, Wherein the right-angle sides of two upside-down right-angled trapezoids are adjacent.

The working process of the windmill of the utility model is like this, depending on the types of crops and the weight, adjust the wind force adjustment knob 2 on the fan 1, so that the crops are subjected to an appropriate wind force during the screening process, and the crops need to be screened from the feed hopper 3. The crops can be more finely screened and the number of screenings can be adjusted by adjusting the feed control panel 4 to adjust the screening volume and screening speed once. In the bellows 5, due to the blowing of the wind, the quality of genuine products is large, and the quality of waste products is light. Like this wind force has less impact on the falling lateral displacement of genuine products, but has a greater impact on the product, so that the genuine product will fall in the genuine product discharge hopper 9 below, and the waste product will fall on the product on the right side of the genuine product discharge hopper 9 In the discharge hopper 7, the slag chips and shell skin are directly discharged from the slag chip outlet 6. Since the genuine product discharge hopper 9 and the waste product discharge hopper 7 have the same cross section, they are all inverted right-angled trapezoidal structures, and two of them are inverted right-angled trapezoidal structures. The right-angled sides of the bellows are adjacent to each other. This structure is not only small in size, but also has a small area to receive genuine and waste products. Because the wind force will weaken when it flows to the right end of the bellows 5, only the cross-sectional area of the slag outlet 6 is less than The cross-sectional area of the bellows 5 can improve the wind flow and increase the wind force, so that no slag remains in the bellows 5 . Finally genuine product and poor product are discharged from genuine product outlet 10 and poor product outlet 8 respectively.
