[0026] 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.

[0027] Example 1, see Figure 1As shown, a grain processing and cleaning device includes a support frame 1. A grain cleaning tank 2 is provided on the top left side of the support frame 1 to provide a cleaning environment for the grain. A cleaning and stirring device 9 is provided inside the grain cleaning tank 2 for cleaning and transporting the grain.

A conveying device 7 is provided on the top of the installation frame 5. Motors 8 are provided on both the left and right sides of the bottom of the support frame 1. Four nozzles 6 are evenly provided on the top of the installation frame 5 for spraying clean water.

[0028] During operation, first add the required clean water to the water tank 3, then pour the grain from the funnel 4 into the grain washing tank 2, turn on the water pump to add clean water to the grain washing tank 2, at which time the motor 8 drives the washing and stirring device 9 to stir the grain for washing. When the grain reaches a certain volume, the washing and stirring device 9 outputs the accumulated grain from the conveying trough and transports it to the conveying device 7. At this time, another motor 8 drives the rotation of the conveying device 7, and at the same time the nozzle 6 starts to spray clean water to further clean the residual dirty water and dust on the surface of the grain.

[0029] Example 2: Based on Example 1, this example adds a water tank 3, a water injection pipe 31, a second water pump 32, a second water delivery pipe 33, a first water pump 34, and a first water delivery pipe 35 to transport clean water, thereby achieving the purpose of deep cleaning of grains.

[0030] The top of the water tank 3 is provided with water outlet 36, water outlet 47 and water outlet 58, which are used to install water injection pipe 31, water delivery pipe 1 35 and water delivery pipe 2 33 respectively, for conveying clean water.

[0031] Specifically, to achieve the above objectives, please refer to Figure 2 , 3 As shown in Figure 4, in this embodiment, the water tank 3 has a water supply pipe 35 and a water supply pipe 33, which are used to supply water to the grain washing tank 2 and the nozzle 6, thereby deeply cleaning the grain.

[0032] The conveyor device 7 is equipped with a conveyor belt 73 for conveying grain. The top of the conveyor belt 73 is equipped with several partitions 71 for separating the grain. The conveyor belt 73 is equipped with a conveyor roller 72 in the middle for driving the conveyor belt 73. The surface of the conveyor belt 73 also has several holes for drainage. The motor 8 drives the conveyor roller 72 to rotate, and the partitions 71 intersect with the mounting frame 5.

[0033] The grain washing tank 2 has a water outlet pipe 25 at the front for discharging wastewater, and a material conveying trough on the right side. The top of the water tank 3 has a water inlet pipe 31, a water delivery pipe 1 35, and a water delivery pipe 2 33. A water pump 1 34 is installed on the water delivery pipe 1 35, and a water pump 2 32 is installed on the water delivery pipe 2 33. The water delivery pipe 1 35 and the water delivery pipe 2 33 extend into the bottom of the water tank 3 for water pumping. The water pump 1 34 and the water pump 2 32 are installed on the top of the water tank 3. The front of the grain washing tank 2 has a water outlet hole 1 21 for installing the water outlet pipe 25. The front of the grain washing tank 2 has a shaft hole 1 22 and a water inlet 23 for installing the water delivery pipe 1 35. The top of the grain washing tank 2 has a funnel hole 24 for installing the funnel 4.

[0034] The mounting frame 5 has shaft holes 52 on both sides, front and back, for mounting conveyor rollers 72. The top of the mounting frame 5 has mounting holes 51 evenly spaced for mounting nozzles 6. The inlets of several nozzles 6 are connected to water supply pipes 33.

[0035] During operation, the clean water in the water tank 3 is pumped by the water pump 34 and delivered through the water pipe 35 from the water inlet 23 into the grain washing tank 2. The motor 8 drives the washing and stirring device 9 to wash and stir the grain, which is then conveyed from the feed inlet to the conveying device 7. The washing and stirring device 9 is installed in the shaft hole 22. The dirty water used to wash the grain flows out from the water outlet 25. At the same time, the clean water in the water tank 3 is pumped by the water pump 32 and delivered through the water pipe 33 to the nozzle 6 to further spray and wash the grain transported from the grain washing tank 2 to the conveying device 7. The conveyor roller 72 moves in the shaft hole 52. The partition 71 isolates the conveyed grain, allowing the sprayed clean water to rinse and wash the grain more thoroughly. The surface of the conveyor belt 73 also has several holes for drainage. The diameter of the holes is smaller than that of ordinary grains, such as wheat, soybeans, and corn kernels.

[0036] Example 3: This example adds a grain washing structure to Example 2 to achieve deep cleaning of the grain.

[0037] For specific details on achieving the above objectives, please refer to [link / reference]. Figure 7 As shown, the washing and stirring device 9 is equipped with a second conveyor roller 91, and another motor 8 drives the second conveyor roller 91 to rotate. The second conveyor roller 91 is installed in the shaft hole 22. Four vertical plates 92 are evenly arranged on the surface of the second conveyor roller 91. Several stirring holes 94 are opened on the surface of the vertical plates 92. Hard brushes 93 are provided on the vertical plates 92 away from the second conveyor roller 91 for sweeping and washing grain.

[0038] At the beginning of operation, a small amount of grain falls into the bottom of the grain washing tank 2 through the stirring hole 94. The hard brush 93 first cleans the small amount of grain. When the grain accumulates to a certain amount, the hard brush 93 sweeps the grain towards the conveying trough during the rotation of the vertical plate 92. Some of the grain slides down the vertical plate 92 again and returns to the water through the hard brush 93. At this time, the hard brush 93 will scrub the grain again. The stirring hole 94 will cause friction between the grains to clean the residual dust on the surface. The hard brush 93 scrubs the surface of the grain at the bottom. Then, the hard brush 93 sweeps the cleaned grain from the conveying port into the conveyor device 7. With the cooperation of the partition 71, the grain is carried into the conveyor belt 73 and cleaned again by several nozzles 6 to remove the turbid liquid from the surface of the grain. The cleaned grain is transported to the end of the conveyor belt 73 for further processing. The hard brush 93 intersects with the bottom of the grain washing tank 2, so that the remaining grain is swept into the conveyor device 7.
