Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, specifically a cleaning device for grain processing. Background Technology

[0002] Grain processing refers to the business activities of transforming raw grains into semi-finished or finished grains, or vice versa. Before processing grains into food, they need to be cleaned to remove surface dust.

[0003] Chinese Patent Publication No. CN212760037U discloses a cleaning device for grain processing, including a tank body. The tank body contains a cleaning chamber and a filter frame. The cleaning chamber has an internal cavity, and the filter frame is located inside the cavity. The filter frame has a placement chamber inside, and its outer wall has several filter holes. The cavity is connected to the placement chamber through the filter holes. A telescopic rod extends the filter frame out of the tank body under the action of a cylinder. Workers can then use a threaded ring and threaded groove to rotate the telescopic rod, removing it from the fixing block and thus disassembling the filter frame. This reduces the hassle of moving the filter frame from the tank body, saving time and effort. A rubber sealing block seals the through-hole and the telescopic rod, reducing the gap between them and preventing water leakage during grain cleaning.

[0004] The cleaning device mentioned in the above patent can clean the dust on the surface of grain. However, grain inevitably contains bran or husk. During cleaning, the bran or husk will float on the water surface because of its light weight, and it needs to be manually retrieved, which is inconvenient. Therefore, we need to propose a cleaning device for grain processing. Utility Model Content

A drain pipe 25 is connected to the bottom of one side of the cleaning box 1, and a control valve is installed on the drain pipe 25.

[0024] The filter screen 20 allows water to flow through the bottom of the storage box 2 into the storage box 2 to rinse and clean the grain. The positioning frame 21 provides auxiliary support for the filter screen 20. The handle 22 allows the user to easily lift the storage box 2 to place it into or remove it from the cleaning box 1. The support frame 23 supports and fixes the storage box 2 in the inner cavity of the cleaning box 1, preventing its bottom from contacting the cleaning components. The drain pipe 25 allows wastewater to be discharged from the cleaning box 1 after cleaning.

[0025] The top of the cleaning tank 1 is fixedly installed with a connecting shell 3. Waste discharge troughs 24 are provided on both sides of the connecting shell 3. A retrieval plate 4 is movably installed inside the connecting shell 3 to retrieve bran and outer shells floating on the water surface inside the cleaning tank 1. A drive assembly for moving the retrieval plate 4 is installed inside the connecting shell 3. The drive assembly includes drive motors 6 fixedly installed at the front and rear ends of one side of the connecting shell 3. The output shaft of the drive motor 6 passes through the connecting shell 3 and extends into the inner cavity of the connecting shell 3, where a drive screw 7 is fixedly installed. The drive screw 7 is located away from... One end of the drive motor 6 is rotatably connected to the inner wall of the connecting shell 3. A slide block 8 is installed on the surface of the drive screw 7. A connecting plate 5 is fixedly installed on the top of the retrieval plate 4. Sliding components for improving the movement stability of the retrieval plate 4 are also provided between the two sides of the connecting plate 5 and the connecting shell 3. The sliding components include slide grooves 14 opened on the front and rear sides of the connecting shell 3. The two ends of the slide grooves 14 are inclined upward. Slide rods 15 that are adapted to the slide grooves 14 are fixedly installed on both ends of the connecting plate 5. The surface of the slide rods 15 is slidably connected to the inner wall of the slide grooves 14.

[0026] During the washing process, bran or husks mixed in with the grain will float on the water surface. At this time, the user can turn on the two sets of drive motors 6 through the external controller. The output shaft of the drive motor 6 will drive the connecting rod 9 to move through the drive screw 7 and the slide 8, and then drive the scooping plate 4 to move through the connecting plate 5. The scooping plate 4 will move along the slide 14 as the track to scoop the bran or husks on the water surface in the washing box 1. After scooping, the bran or husks on the scooping plate 4 can be cleaned through the waste discharge trough 24.

[0027] It is worth noting that the top of the connecting plate 5 is movably connected to the drive assembly through an elastic connecting component.

[0028] By setting up the elastic connection component, the salvage plate 4 and the slide block 8 can be elastically connected together. During the process of the slide block 8 driving the salvage plate 4 to move and salvage the bran and shells on the water surface, the connecting plate 5 will move downward under the action of the slide rod 15, so that the bottom of the salvage plate 4 is submerged in the water. At this time, the movement of the connecting plate 5 will drive the top plate 12 to move through the connecting rod 9, so as to compress the compression spring 13. After the salvage is completed, the salvage plate 4 will move to both sides of the inner cavity of the connecting shell 3. At this time, the reaction force generated by the contraction of the compression spring 13 and the guiding action of the slide groove 14 will drive the salvage plate 4 to move upward to the waste discharge trough 24. The user can clean the bran or shells on the salvage plate 4 through the waste discharge trough 24.
