The hulling mechanism 2 and the vibrating sieve mechanism 3 are sequentially arranged inside the housing 1 from top to bottom. The chip suction mechanism 4 is arranged on one side of the housing 1, and its air inlet is communicated with one side of the vibrating sieve mechanism 3. Among them, the vibrating sieve mechanism 3 includes: a multi-layer vibrating sieve assembly 301 and a driving assembly 302. The multi-layer vibrating sieve assembly 301 is arranged inside the housing 1 so as to be reciprocally movable in the vertical direction, and can realize multi-stage screening of oat grains and husks. The driving assembly 302 is arranged on the housing 1 to drive the multi-layer vibrating sieve assembly 301 to reciprocally move in the vertical direction.

[0031] In this application, oats are added through the open mouth at the upper end of the housing 1, hulled by the hulling mechanism 2, and then fall onto the multi-layer vibrating sieve assembly 301. The driving assembly 302 drives the multi-layer vibrating sieve assembly 301 to reciprocally move in the vertical direction for vibrating screening. During the vibrating screening process, since the weight of oat grains is greater than that of oat husks, the chip suction mechanism 4 will only suck away the oat husks, and the oat grains will continue to fall under the action of the multi-layer vibrating sieve mechanism 3. Since the multi-layer vibrating sieve mechanism 3 can perform multi-stage screening on oat grains, the vibrating screening time of oats is extended to ensure that the chip suction mechanism 4 can fully separate oat grains and husks.

A chip outlet mesh 3010101 communicated with the air inlet of the chip suction mechanism 4 is arranged on one side of the collection frame 30101.

[0033] In this application, a plurality of sieve meshes 30102 are arranged inside the collection frame 30101 to extend the vibrating screening time of oats, and the chip outlet mesh 3010101 is arranged to prevent oat grains from entering the chip suction mechanism 4 through the air inlet during vibration.

[0034] Referring to Figure 4 and Figure 5: The driving assembly 302 includes: a first driving motor 30201, a rotating disk 30202, an eccentric roller 30203, and a linkage rod 30204. The first driving motor 30201 is disposed on one side of the housing 1, and its output end horizontally extends into the housing 1 and is located below the vibrating screen mechanism 3. The rotating disk 30202 is coaxially disposed at the output end of the first driving motor 30201. One end of the eccentric roller 30203 is disposed at a position deviating from the axis of the rotating disk 30202, and the other end is horizontally disposed. One end of the linkage rod 30204 is hinged to the eccentric roller 30203, and the other end is hinged to the collection frame 30101.

[0035] In this application, by starting the first driving motor 30201 to drive the rotating disk 30202 to rotate, the collection frame 30101 is driven to reciprocate in the vertical direction through the eccentric roller 30203 and the linkage rod 30204. Here, a plurality of linkage rods 30204 are provided to connect the eccentric roller 30203 and the collection frame 30101 to ensure that the collection frame 30101 can stably reciprocate in the vertical direction.

[0036] Refer to Figure 4 and Figure 5 : On the opposite two side walls of the collection frame 30101, limiting sliders 3010102 are vertically provided respectively. On the opposite two inner side walls of the housing 1, limiting chutes 101 corresponding to each limiting slider 3010102 are provided respectively.

[0037] In this application, by providing the limiting sliders 3010102 and the limiting chutes 101, it is ensured that the collection frame 30101 can stably reciprocate in the vertical direction.

[0038] Refer to Figure 5 : The peeling mechanism 2 includes: a first peeling roller 201, a second peeling roller 202, a second driving motor 203, and a third driving motor 204. The first peeling roller 201 and the second peeling roller 202 which cooperate with each other are disposed above the vibrating screen mechanism 3 in the housing 1. The second driving motor 203 is disposed on the housing 1, and its output end is coaxially fixed to the first peeling roller 201. The third driving motor 204 is disposed on the housing 1, and its output end is coaxially fixed to the second peeling roller 202. The second driving motor 203 and the third driving motor 204 drive the first peeling roller 201 and the second peeling roller 202 respectively at different output speeds.

[0039] In this application, by starting the second driving motor 203 and the third driving motor 204 to drive the first peeling roller 201 and the second peeling roller 202 to rotate respectively. Here, the rotation speeds of the second driving motor 203 and the third driving motor 204 are different, so that a differential speed is generated between the first peeling roller 201 and the second peeling roller 202 to rub the oats open, and thus the peeling operation of the oats is realized.

[0040] Refer to Figure 2 : Above the first peeling roller 201 and the second peeling roller 202 inside the housing 1, there is a scraping plate 102 with one side fitting the surfaces of the first peeling roller 201 and the second peeling roller 202 respectively.

[0041] In this application, by setting the scraping plate 102, it is ensured that all oats are rubbed open to prevent oats from slipping off the outer sides of the first peeling roller 201 and the second peeling roller 202, thereby improving the oat peeling effect.

[0042] Refer to Figure 3 : The side of the scraping plate 102 that fits the first peeling roller 201 or the second peeling roller 202 is provided with a flexible layer 10201.

[0043] The setting of the flexible layer 10201 in this application can better adapt to the surface shape of the peeling roller, ensure the degree of fit between the scraping plate 102 and the peeling roller, reduce the friction between the scraping plate 102 and the peeling roller, lower the wear degree, and extend the service life of the equipment.

[0044] Refer to Figure 3 : On the opposite sides of the open part above the housing 1, there are symmetrically arranged guide plates 103, and the lower side of the guide plates 103 is above the joint of the first peeling roller 201 and the second peeling roller 202.

[0045] The setting of the guide plates 103 in this application can guide the oat grains to slide down to the joint of the peeling rollers, reduce the possibility of oat grains slipping off the outer sides of the peeling rollers, and thus improve the peeling efficiency.

[0046] Refer to Figure 2 and Figure 3 : The chip suction mechanism 4 includes: a chip suction pipe 401, a chip collection box 402, and an induced draft fan 403. The chip collection box 402 is arranged on one side of the housing 1. One end of the chip suction pipe 401 is communicated with the chip collection box 402, and the other end is communicated with the inside of the collection frame 30101 through a chip outlet net 3010101. The induced draft fan 403 is arranged on one side of the chip collection box 402, and its air inlet is communicated with the chip suction pipe 401.

[0047] In this application, by starting the induced draft fan 403, the oat husks in the collection frame 30101 are sucked into the chip collection box 402 through the chip suction pipe 401 and the chip outlet net 3010101. The wind force of the induced draft fan 403 here is controlled to the extent that it can only suck oat husks but cannot suck oat grains.

[0048] When the device provided by the utility model is in use, oats are added through the open mouth at the upper end of the outer shell 1, peeled by the peeling mechanism 2, and then fall onto the multi-layer vibrating screen assembly 301. The driving assembly 302 drives the multi-layer vibrating screen assembly 301 to reciprocate vertically to perform vibrating screening. During the vibrating screening process, since the weight of the oat grains is greater than the weight of the oat husks, the chip suction mechanism 4 will only suck away the oat husks, and the oat grains will continue to fall under the action of the multi-layer vibrating screen mechanism 3. Since the multi-layer vibrating screen mechanism 3 can perform multi-stage screening on the oat grains, the vibrating screening time of the oats is extended to ensure that the chip suction mechanism 4 can fully separate the oat grains and the husks.
