Description

Technical Field

[0001] This utility model relates to the field of agricultural and grain machinery technology, and in particular to a Sacron-type dual-channel rotary vibrating cleaning screen. Background Technology

[0002] The vibrating screen works by using the reciprocating rotary vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration. The vibrating screen is equipped with screens of various mesh sizes, which separates impurities of various sizes in the grain. At present, in order to prevent the vibrating screen from clogging and increase the screening effect, air is usually blown into the screen through the air supply mechanism to separate the grain from other impurities.

[0003] Currently, when using vibrating cleaning screens, the surface of the screened grain is often covered with small particles of dust and impurities, resulting in low grain cleanliness. This makes the grain unsuitable for further processing and production, and can lead to pests and diseases during storage. Utility Model Content

[0004] The main purpose of this invention is to provide a Sacron-type dual-channel vibrating cleaning screen, which can effectively solve the problem of small particle impurities mixed in with the screened grain.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The Sacron-type dual-channel rotary vibrating cleaning screen includes a support frame and a third air guide channel. The main body of the rotary vibrating screen is installed on the support frame through several booms. A first screening plate and a second screening plate are installed inside the main body of the rotary vibrating screen. The mesh size of the first screening plate is smaller than that of the second screening plate.

[0007] The support is equipped with a flow equalization box and a feed box. The feed box is installed on the upper side of the flow equalization box. The flow equalization box is installed on one side of the main body of the vibrating screen. A plurality of first flow equalization plates are installed in the feed box. A second flow equalization plate is installed in the flow equalization box. The first flow equalization plates and the second flow equalization plates are arranged opposite to each other.

[0008] A first air guide groove is installed on one side of the feed box, and a second air guide groove is installed on the bracket. One end of the first air guide groove is installed on the second air guide groove, and the other end of the first air guide groove is configured to cooperate with the first flow equalization plate inside the feed box. The second air guide groove is divided into two ends, and the cylindrical part of the Sacron dust collector is installed on both ends of the second air guide groove.

[0009] Preferably, the bracket is fitted with casters on its lower side.

[0010] Preferably, a conical part of the Sacron dust collector is fitted to the lower end of the cylindrical part of the Sacron dust collector, a fan is fitted to the upper end of the cylindrical part of the Sacron dust collector, and a first drive motor is fitted to the upper side of the fan.

[0011] Preferably, the lower end of the conical part of the Sacron dust collector is fitted with an ash discharge auger, one end of which is provided with a one-way cover, and the other end of which is fitted with a second drive motor.

[0012] Preferably, the vibrating screen body is provided with a large particle impurity outlet, a small particle impurity outlet and a grain outlet. The large particle impurity outlet is located above the first screening plate, the grain outlet is located between the first screening plate and the second screening plate, and the small particle impurity outlet is located below the second screening plate. A feed pipe is installed on the support, and the feed pipe is configured to cooperate with the large particle impurity outlet.

[0013] Preferably, an eccentric motor is installed at the lower end of the main body of the vibrating screen, and a conveyor belt is installed on the support, with the conveyor belt configured to cooperate with the grain outlet.

[0014] Preferably, a flow divider is installed in the first air guide groove, a first regulating valve is installed in the first air guide groove, and a second regulating valve is installed in the third air guide groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The rotary vibrating cleaning screen of this utility model performs two dust removal cleaning processes using Sacron, which fully separates the grain from the dust on its surface. The air inlet below the flow equalization plate can absorb light dust. The gas containing dust enters the second air inlet through the first air guide groove, and then enters the Sacron dust collector for the first dust removal operation. The second air separation is located at the grain outlet of the vibrating screen, which can recover the light impurities generated during the vibration screening process, effectively improving the cleanliness of the grain. This makes the grain less susceptible to diseases and pests in the storage room, further improving the safety of the grain.

[0017] 2. In the screening of grain, this utility model first distributes the grain evenly through a flow equalization plate. During this process, the grain strikes the flow equalization plate, causing the grain to separate from the impurities on its surface for the first time. At this point, the Sacron dust collector removes small particulate impurities for the first time. When the grain enters the vibrating screen for screening, the first and second screening plates rub against the grain, causing the impurities on its surface to fall off further, which is considered the second impurity removal. Large particulate impurities remain on the first screening plate and are discharged, while small particulate impurities pass through the second screening plate and are discharged. When the grain is discharged from the outlet, the Sacron dust collector removes small particulate impurities for the first time, further improving the surface cleanliness of the grain, effectively reducing the occurrence of pests and diseases in the grain, and further improving the safety of the grain.

[0018] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1-8 As shown, the Sacron-type dual-duct rotary vibrating cleaning screen includes a support 101 and a third air guide 311. The main body of the rotary vibrating screen 201 is installed on the support 101 through several booms 202. The main body of the rotary vibrating screen 201 is fitted with a first screening plate 210 and a second screening plate 211. The mesh number of the first screening plate 210 is smaller than that of the second screening plate 211.

[0030] In this embodiment, the first screening plate 210 filters out impurities larger than the grain, and the second screening plate 211 filters out impurities smaller than the grain, so that the grain is located between the first screening plate 210 and the second screening plate 211, thus achieving three-layer diversion.

[0031] A flow equalization box 103 and a feed box 104 are installed on the support 101. The feed box 104 is installed on the upper side of the flow equalization box 103. The flow equalization box 103 is installed on one side of the vibrating screen body 201. Several first flow equalization plates 105 are installed in the feed box 104. Second flow equalization plates 106 are installed in the flow equalization box 103. The first flow equalization plates 105 and the second flow equalization plates 106 are arranged opposite to each other.

[0032] In this embodiment, the grain entering the feed box 104 can be evenly distributed by the flow equalization plate. When the grain passes through the flow equalization plate, it will strike the corresponding flow equalization plate. During this process, the grain is separated from the dust on its surface. The first air guide groove 301 below the flow equalization plate can absorb light dust. The gas with dust enters the second air guide groove 312 through the first air guide groove 301 and then enters the Sacron dust collector for the first dust removal operation.

[0033] A first air guide groove 301 is installed on one side of the feed box 104, and a second air guide groove 312 is installed on the bracket 101. One end of the first air guide groove 301 is installed on the second air guide groove 312, and the other end of the first air guide groove 301 is set to cooperate with the first flow equalization plate 105 in the feed box 104. The second air guide groove 312 is divided into two sections. Both ends of the second air guide groove 312 are fitted with cylindrical parts 304 of a Saclon dust collector. A conical part 307 of a Saclon dust collector is installed at the lower end of the cylindrical part 304. A fan 305 is installed at the upper end of the cylindrical part 304. A first drive motor 306 is installed on the upper side of the fan 305. An ash discharge auger 308 is installed at the lower end of the conical part 307 of the Saclon dust collector. One end of the ash discharge auger 308 is provided with a one-way cover 309, and the other end of the ash discharge auger 308 is fitted with a second drive motor 310.

[0034] The main body 201 of the vibrating screen is provided with a large particle impurity outlet 203, a small particle impurity outlet 205 and a grain outlet 204. The large particle impurity outlet 203 is located above the first screening plate 210, the grain outlet 204 is located between the first screening plate 210 and the second screening plate 211, and the small particle impurity outlet 205 is located below the second screening plate 211. A feed pipe 207 is installed on the support 101, and the feed pipe 207 is configured to cooperate with the large particle impurity outlet 203.

[0035] Specifically, the grain outlet 204 in this application has several openings, as shown in the figure and Figure 8 When there is no grain outlet opening at outlet 204 (refer to...) Figure 7 The horizontal projection area of ​​the waterfall formed by the falling grain is small, and the grain cannot be well separated from the debris or other small particles separated by vibration. When a grain outlet opening is provided at outlet 204 (refer to...) Figure 8 The waterfall formed by the falling grain has a large horizontal projection area, which makes it difficult to separate the grain from the debris or other small particles separated by vibration. This facilitates the next step of the second dust removal operation, effectively reduces impurities in the grain screened by vibration, and makes the screened grain cleaner.

[0036] An eccentric motor 212 is installed at the lower end of the main body 201 of the vibrating screen. A conveyor belt 206 is installed on the support 101 and is configured to cooperate with the grain outlet 204. A caster 102 is installed on the lower side of the support 101. A diverter plate 303 is installed inside the first air guide groove 301, which can divide the first air guide groove 301 into two air channels (see reference). Figure 3 ), refer to Figure 5In the diagram, the black arrow represents the grain to be screened, the white arrow represents the gas containing light dust, and the hollow arrow represents the falling direction of the clean grain. The first air guide trough 301 is equipped with a first regulating valve 302, and the third air guide trough 311 is equipped with a second regulating valve 313. The vibrating screen body 201 shakes due to the lateral reciprocating impact force generated by the eccentric motor 212, thereby completing the screening operation.

[0037] It should be noted that, in the application, the grain to be screened is first fed into the vibrating screen through the feed box 104 and the flow equalization box 103. During this process, the grain falls onto the corresponding flow equalization plates. When the grain comes into contact with the flow equalization plates, it strikes the plates due to its own gravity, causing impurities on the grain to separate from the grain, thereby improving the screening effect. When the grain passes through the flow equalization plates, smaller dust or impurities float in the feed box 104. At this time, the Sacron dust collector absorbs and removes the dust floating in the gas in the feed box 104. The grain then enters the vibrating screen body 201, first falling onto the first screening plate 210. When the main body 201 vibrates, the grain will gradually move towards the grain outlet 204. During this process, the grain and small particle impurities will pass through the first screening plate 210, while large particle impurities will remain on the first screening plate 210 and be discharged through the large particle impurity outlet 203. Small particle impurities will pass through the second screening plate 211 and be discharged through the small particle impurity outlet 205. The grain will remain on the second screening plate 211 and be discharged through the grain outlet 204. When the grain is discharged from the grain outlet 204, the third air guide groove 311 connected to the Sacron dust collector will also perform another adsorption and impurity removal on the grain discharged from the grain outlet 204, effectively improving the purity of the screened grain.
