[0024] See also Figure 1-Figure 7 A grading device for rice processing includes a vibrating bed 1 and a screening plate 2. The vibrating bed 1 is provided with a fixing mechanism 4 for fixing the screening plate 2. The upper end of the vibrating bed 1 is provided with a feeding mechanism 3.
[0025] The vibration bed 1 includes a bed body 101, a vibration motor 102, a first spring 104 and a support base 103. The bottom of the bed body 101 is provided with a first discharge port 1011 and a second discharge port 1012. The first spring 104 is fixedly mounted on the upper end of the support base 103. The bed body 101 is fixedly mounted on the upper end of the first spring 104. The vibration motor 102 is fixedly mounted on the front end surface of the bed body 101. The fixing mechanism 4 includes a first fixing plate 401, a second fixing plate 402, a second spring 404 and a latch 403. The second fixing plate 402 is provided with a second spring 404 and a latch 403. Plate 402 is installed on the inner end surface of the bed body 101, a third slide groove 4021 is provided on the second fixed plate 402, and a rotating shaft 203 that slides with the third slide groove 4021 is provided on the front and rear sides of the screening plate 2. The first fixed plate 401 is installed on the upper end surface of the bed body 101 away from the end of the second fixed plate 402, the pin 403 and the spring are installed in the first fixed plate 401, the pin 403 is elastically connected to the first fixed plate 401 through the second spring 404, and the side of the screening plate 2 is provided with a pin hole 202 that cooperates with the pin 403.
[0026] Furthermore, the side end face of the first fixed plate 401 is provided with a guide hole 4011 that cooperates with the pin 403, a second slide groove 4012 is provided in the guide hole 4011, the side end face of the pin 403 is provided with a limit plate 4031 that slides with the second slide groove 4012, and the upper end face edge of the pin 403 is chamfered.
[0027] The second slide groove 4012 and the limit plate 4031 cooperate to limit the sliding of the latch 403. The edge of the upper end surface of the latch 403 is chamfered so that when the screen presses the latch 403, the latch 403 is subjected to the horizontal component of force and can automatically be retracted into the guide hole 4011. When the latch 403 is aligned with the pin hole 202, the latch 403 is automatically inserted into the pin hole 202 under the resetting action of the second spring 404.
[0028] Furthermore, the third sliding groove 4021 includes a vertical section and a horizontal section. The bottom of the vertical section is connected to the right side of the horizontal section, and the top of the vertical section is connected to the upper end surface of the second fixing plate 402.
[0029] The rotating shafts 203 on the front and rear sides of the vibrating screen can slide along the third slide groove 4021. When sliding from the vertical section to the horizontal section, the longitudinal displacement of the screening plate 2 close to the second fixed plate 402 is restricted. When the pin 403 is inserted into the pin hole 202, the longitudinal displacement of the screening plate 2 close to the first fixed plate 401 is restricted. Due to the horizontal spacing between the first fixed plate 401 and the second fixed plate 402, the screening plate 2 is also restricted in the horizontal direction, thereby fixing the screening plate 2.
[0030] Furthermore, the feeding mechanism 3 includes a feeding hopper 301, a driving motor 302, a controller 303, an isolation plate 305 and a discharge roller 304. The driving motor 302 is fixedly mounted on the front end surface of the feeding hopper 301, the discharge roller 304 is fixedly mounted on the output shaft of the driving motor 302, and the controller 303 is fixedly mounted on the front end surface of the bed 101 and is electrically connected to the driving motor 302.
[0031] The discharge roller 304 is driven to rotate by the motor, so that the discharge roller 304 delivers the rice in the feeding hopper 301 to the screening plate 2. The controller 303 controls the speed of the driving motor 302, thereby controlling the rotation speed of the discharge roller 304, thereby achieving the regulation of the discharge speed, reducing the poor discharge caused by rice accumulation, or reducing the impact of rice accumulation on the screening effect.
[0032] Furthermore, the discharge roller 304 includes a central axis 3041 and material-discharging blades 3042. The material-discharging blades 3042 are arranged in an equidistant circular array on the side end face of the central axis 3041. The number of the material-discharging blades 3042 is six. The isolation plate 305 is installed in the feeding hopper 301. The side end face of the isolation plate 305 is provided with an arc groove that fits the discharge roller 304.
[0033] The material-discharging fan blades 3042 on the side of the central axis 3041 divide the space between the two groups of isolation plates 305 into six areas. As the discharge roller 304 rotates, each area discharges material in turn. When the discharge roller 304 stops rotating, the equipment stops feeding, thereby strictly controlling the material discharge speed, ensuring that the rice is evenly spread on the screening plate 2, and improving the screening effect.
[0034] Furthermore, the feeding hopper 301 is provided with a rotatably connected roller 3011 .
[0035] The friction between the rice packaging bag and the feeding hopper 301 is reduced by the rotating roller 301, thereby facilitating the removal of the packaging bag after feeding, thereby improving the convenience of operation.
[0036] Furthermore, a handle 201 is provided on the upper end surface of the screening plate 2 , there are two latches 403 , and a connecting rod 4032 is provided between the two groups of latches 403 .
[0037] The screen plate 2 can be conveniently lifted up by the handle 201, thereby making it convenient to remove the screen plate 2 and quickly replace the screen plates 2 of different specifications. The two sets of pins 403 can be pulled out at the same time through the connecting rod 4032, further improving the convenience of operation.
[0038] When using this device, select a screening plate 2 of appropriate specifications, determine its mesh size and other parameters according to the rice processing requirements, align the rotating shafts 203 on both sides of the screening plate 2 with the vertical section entrance of the third slide groove 4021 on the second fixed plate 402, and then slide the screening plate 2 downward along the vertical section until the rotating shaft 203 slides to the horizontal section. At this time, the longitudinal displacement of the screening plate 2 close to the second fixed plate 402 is restricted, and the screening plate 2 is pressed down until the latch 403 is aligned with the pin hole 202 on the side of the screening plate 2. The latch 403 is reset by the spring. The pin 202 is automatically inserted into the pin hole 202, thus limiting the displacement of the screening plate 2 and fixing it horizontally. The rice bag is placed above the feeding hopper 301, with the bag opening aligned with the entrance of the feeding hopper 301. Since the feeding hopper 301 is provided with a rotatably connected roller 3011, the roller 3011 can be used to reduce the friction between the bag and the feeding hopper 301, facilitating the pouring of rice into the feeding hopper 301. The controller 303 is turned on to set the speed of the drive motor 302, thereby controlling the rotation speed of the discharge roller 304. The drive motor 302 drives the discharge roller 304 to rotate. The central axis 3041 and six feeding blades 3042 of the discharge roller 304 divide the space between the two sets of isolation plates 305 into six areas. As the discharge roller 304 rotates, each area discharges rice in turn, ensuring that the rice is evenly spread on the screening plate 2. According to the actual screening situation and rice flow demand, the motor speed can be adjusted in time through the controller 303 to achieve the best feeding effect, and the vibration motor 102 is started to make the bed 101 start to vibrate. During the vibration process, the rice is graded on the screening plate 2 as it vibrates. Smaller rice particles fall through the mesh of the screening plate 2, and larger rice particles remain on the screening plate 2, achieving a preliminary grading effect.
[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
