[0005] To solve the above-mentioned technical problems, this utility model provides a cleaning device for grain production and processing, including a cleaning box. The top of the cleaning box has an inlet, and an inlet trough is fixedly connected to the middle of the inlet. A sieve plate is fixedly connected to the middle of the cleaning box. A support is fixedly connected between the inner walls of both sides of the cleaning box. A rotating column is rotatably connected between the support and the bottom wall of the cleaning box. Multiple vertically arranged stirring ribs are fixedly connected to the middle of the rotating column. A drain is opened on one side of the cleaning box, located between the support and the bottom wall of the cleaning box. A water inlet is opened in the middle of one side of the cleaning box, and a discharge port is opened at the bottom of the other side of the cleaning box. Slides are opened on both sides of the discharge port, and a baffle is set in the middle of the slide. This shortens the soaking time of the grain in water, avoids the impact of prolonged soaking on the quality of the grain, and enables the classified collection of impurities of different sizes, facilitating subsequent collection and processing.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0025] like Figure 1-6 As shown: This embodiment provides a cleaning device for grain production and processing, including a cleaning box 100. The top of the cleaning box 100 is provided with an inlet 101. An inlet trough is fixedly connected to the middle of the inlet 101. A sieve plate 102 is fixedly connected to the middle of the cleaning box 100. A plurality of sieve openings are provided in the middle of the sieve plate 102. The diameter of the sieve openings is larger than the diameter of the grain. A groove 112 is provided in the middle of one side of the cleaning box 100. The side of the sieve plate 102 near the groove 112 is lower than the side away from the groove 112. The groove 112 corresponds to the horizontal position of the lower end of the sieve plate 102. A collection trough 113 is fixedly connected to one side of the groove 112.
[0026] During cleaning, grains enter the cleaning box 100 through the feed chute. When the grains pass through the sieve plate 102, larger impurities and dirt are blocked by the sieve plate 102, thus achieving initial cleaning. The grains continue to fall through the sieve plate 102, while impurities and dirt slide down the inclined surface of the cleaning box 100 into the collection trough 113, so that impurities can be discharged in an orderly manner, avoiding the problem of disorderly discharge and maintaining a clean and tidy production environment.
[0027] Rotating column 104 Figure 2 As shown,
[0028] A bracket 103 is fixedly connected between the inner walls of both sides of the cleaning box 100. A rotating column 104 is rotatably connected between the bracket 103 and the bottom wall of the cleaning box 100. Multiple stirring ribs 105 arranged in an upper and lower array are fixedly connected to the middle of the rotating column 104. A motor 111 is fixedly connected to the center of the bottom of the cleaning box 100. The output shaft of the motor 111 is fixedly connected to the bottom of the rotating column 104. Multiple support columns 117 are fixedly connected to the bottom of the cleaning box 100. A water inlet 107 is opened in the middle of one side of the cleaning box 100. The water inlet 107 is connected to an external water source. A drain 106 is opened on one side of the cleaning box 100. The water inlet 107 is set higher than the drain 106. The drain 106 is located between the bracket 103 and the bottom wall of the cleaning box 100. A collection box is set on one side of the drain 106.
[0029] Grains fall onto the bottom wall of the cleaning tank 100 through the sieve plate 102, and then external water is introduced through the water inlet 107. After the water completely submerges the grains, the motor 111 is started and stopped, driving the rotating column 104 to rotate, causing the grains to be stirred inside the cleaning tank 100, further removing impurities and dirt from the surface of the grains. During the stirring process, impurities are stirred by the stirring ribs 105 on the rotating column 104. The design of the stirring ribs 105 avoids the damage to the grains caused by the excessive contact surface between the blades and the grains, as is the case with traditional grains. Impurities are separated from the grains; larger impurities are filtered by the sieve plate 102, while smaller and lighter impurities float on the horizontal surface. Water is continuously added through the water inlet 107, ultimately making the grains... The water level is higher than the drain 106, and the surface water flows out of the cleaning tank 100, carrying away floating impurities and cleaning the grains. The water containing impurities enters the collection tank for collection. The pretreatment by the sieve plate 102 and the stirring by the stirring ribs 105 shorten the soaking time of the grains in water, avoiding the impact of long-term soaking on the quality of the grains, while improving cleaning efficiency. The sieve plate 102 and the drain 106 enable the classified collection of impurities of different sizes, facilitating subsequent collection and processing. The support column 117 supports the cleaning tank 100, ensuring the stability of the cleaning tank 100, and also provides space for the installation of the motor 111 at the bottom of the cleaning tank 100.
[0030] Sealing block 116 Figure 5 , 6 As shown,
[0031] The bottom of the cleaning box 100 is provided with a water outlet 114, a filter screen 115 is fixedly connected to the middle of the water outlet 114, and a sealing block 116 is threadedly connected to the middle of the water outlet 114.
[0032] After cleaning, the sealing block 116 is rotated open, and the water in the cleaning tank 100 flows out through the outlet 114. The filter screen 115 is used to intercept residual impurities and prevent them from flowing out with the water. To ensure the sealing of the outlet 114, the outlet 114 is threaded with a sealing block 116 in the middle. During cleaning, the sealing block 116 can be tightened to keep the outlet 114 sealed.
[0033] baffle 110 Figure 2 , 4 As shown,
[0034] A discharge port 108 is provided on the bottom of the other side of the cleaning box 100. Slide grooves 109 are provided on both sides of the discharge port 108. A baffle 110 is provided in the middle of the slide groove 109. A pressure plate is provided on one side of the baffle 110. Limiting plates 118 are fixedly connected to both ends of the bottom of the baffle 110. Limiting rods 119 are slidably connected to the middle of each limiting plate 118. Two vertically arranged limiting rods are provided on the sides of the support column 117 adjacent to the limiting rods 119. The inner diameter of the limiting port 120 is the same as the diameter of the limiting rod 119. When the baffle 110 is closed, the limiting rod 119 is located in the adjacent upper limiting port 120. The vertical position of the limiting port 120 and the limiting rod 119 is the same. The side of the limiting rod 119 away from the support column 117 is fixedly connected to the pull rod 121. The rod body of the limiting rod 119 located between the pull rod 121 and the limiting plate 118 is sleeved with a spring 122.
[0035] After the water is discharged, the operator pulls the lever 121, causing the limiting rod 119 to move out of the upper limiting port 120. Then, the baffle 110 moves down, causing the baffle 110 to move the limiting plate 118 and the limiting rod 119 down. When the limiting rod 119 moves down to the height of the lower limiting port 120, the elastic force of the spring 122 causes the limiting rod 119 to extend and engage in the limiting port 120, thereby achieving limiting control of the bottom of the cleaning box 100 and keeping the discharge port 108 in the open state for easy discharge. After the discharge is completed, by pulling the lever 121, the limiting rod 119 can be removed from the limiting port 120. The operator moves the baffle 110 and the limiting plate 118 upward, so that the limiting rods 119 are inserted into the adjacent upper limiting ports 120, thereby closing the discharge port 108.
[0036] Working principle:
[0037] First, the grains enter the cleaning chamber through the feed chute. As they pass through the sieve, larger impurities and dirt are blocked by the sieve, which has a larger diameter than the grains, achieving initial cleaning. The grains then continue to fall through the sieve, while impurities and dirt slide down the inclined surface of the cleaning chamber into the collection trough for orderly discharge. During the cleaning process, the grains fall onto the bottom wall of the cleaning chamber and are introduced into the water source through the inlet. After the grains are completely submerged in water, the motor starts, driving the rotating column and stirring ribs to rotate, further removing impurities and dirt from the surface of the grains. During stirring, impurities are carried away and separated; larger impurities are filtered through the sieve, while smaller impurities are discharged with the water flow. After cleaning, the water outlet is opened by rotating the sealing block, allowing the water in the cleaning chamber to flow out. The filter screen intercepts residual impurities. The discharge port at the bottom of the cleaning chamber opens or closes the baffle by operating the limit rod, allowing the grains to be discharged.
[0038] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
