[0001] The present invention relates to a feeding device, in particular to a feeding and sparging device and a dryer. Background Art

[0002] Rice is a refined product of rice. During the processing and production of rice, it is necessary to screen and filter the rice in order to filter out impurities in the rice. A flat rotary screen can be selected to screen the rice. When using a flat rotary screen, a rice feeding device will be selected for use in combination in order to better feed the material.

The support frame 11 is provided with two, and the upper part of the support frame 11 is slidably connected to the connecting rod 12, and the screed box 1 is connected between the connecting rods 12. The bottom of the screed box 1 is evenly provided with six feed ports, and the bottom of the screed box 1 is slidably connected to six of the seals 13, and the seals 13 are used to block the feed ports. The rear side of the bottom of the screed box 1 is rotatably connected. The rotating screw 14 is threadedly connected to the sealing member 13 at the rear. Two heating tubes 15 are connected to the front and rear sides of the inner wall of the screed box 1. The upper left part of the screed box 1 is slidably connected to the lower pressure frame 17. The steel mesh 16 is arranged in the lower pressure frame 17. The upper right part of the screed box 1 is provided with a driving assembly for driving the steel mesh 16 to move downward. The driving assembly is connected to the right part of the lower pressure frame 17. The bottom of the connecting rod 12 on the right is connected to the connecting cylinder 25. A device for driving the connecting cylinder 25 to move left and right is provided between the lower pressure frame 17 and the support frame 11 on the right. The moving assembly that moves to the right, the upper part of the support frame 11 on the right is slidably connected to the moving frame 23, and the moving frame 23 and the connecting cylinder 25 are movably connected; the driving assembly includes a rotating screw 18, a driving motor 19 and a support 110, the upper right part of the screed box 1 is welded with the support 110, the upper part of the support 110 is connected to the driving motor 19 by bolts, and the lower part of the output shaft of the driving motor 19 is connected to the rotating screw 18 through a coupling, the lower part of the rotating screw 18 is rotatably connected to the screed box 1, and the rotating screw 18 and the right part of the lower pressure frame 17 are threaded The movable assembly includes a guide downward moving part 2, a driving screw rod 21, a rotating disk 22, a support disk 24 and a nut 26.

[0036] When people need to use the present feeding and scrambling device and dryer to pour rice evenly into the flat rotary screen, they first dock the feeding port of the flat rotary screen with the bottom of the scrambling box 1, then rotate the rotating screw rod 14 to drive the sealing member 13 to move to the right to open the feeding port, and then pour the rice into the scrambling box 1, and turn on the driving motor 19 and the heating tube 15. The heating tube 15 can automatically dry the rice, so that the rice that has agglomerated with water can be dried so as to disperse the rice. The driving motor 19 controls the rotating screw rod 18 to rotate forward and backward, and the rotating screw rod 18 rotates forward and backward to drive the lower pressing frame 17 and the wire mesh 16 to move up and down. When the wire mesh 16 moves downward and contacts the rice, the wire mesh 16 can cut the agglomerated rice, and when the lower pressing frame 17 moves downward, it also drives the guide downward moving member 2 and the nut 2 6 moves downward, and the nut 26 moves downward, which drives the driving screw rod 21 and the rotating disk 22 to rotate.

The left and right movement of the connecting rod 12 can drive the material-scraping box 1 to move left and right continuously. In this way, the material-scraping box 1 can continuously shake the rice, and cooperate with the wire mesh 16 to cut the agglomerated rice, so that the rice passes through the feed port evenly into the flat rotary screen. When the lower pressing frame 17 and the wire mesh 16 move upward and reset, the nut 26 is also driven to move upward and reset. When the feeding and scrambling device and the dryer are not in use, the driving motor 19 and the heating tube 15 are turned off, and the rotating screw rod 14 is manually reversed to drive the seal 13 to move left and reset.

[0037] Example 2

[0038] On the basis of Example 1, Figure 6-Figure 7As shown, it also includes a scattering mechanism for scattering the rice, which is arranged between the upper rear part of the screed box 1 and the lower pressing frame 17, and the scattering mechanism includes a scattering frame 3, a return spring 31, a guide rod 32 and a toggle assembly. The left and right sides of the rear top of the lower pressing frame 17 are connected to the guide rods 32, and the scattering frame 3 for scattering the rice is slidably connected between the guide rods 32. The return spring 31 is connected between the left and right sides of the scattering frame 3 and the upper part of the guide rod 32, and the toggle assembly for intermittently driving the scattering frame 3 to move up and down is provided between the rear part of the scattering frame 3 and the rear part of the lower pressing frame 17. During the downward movement of the lower pressing frame 17, the scattering frame 3 can be continuously moved up and down to scatter the rice through the toggle assembly; The dynamic component includes a pressure rod 33, a rotating member 34, a rotating gear 35, a missing rack 36 and a guide member 37. The pressure rod 33 is connected to the middle of the rear part of the falling frame 3, and the guide member 37 is connected to the middle of the upper rear part of the lower pressure frame 17. The upper part of the guide member 37 is rotatably connected to the rotating member 34. The rotating member 34 and the upper part of the pressure rod 33 are squeezed together. The right part of the rotating member 34 is connected to the rotating gear 35, and the middle of the upper rear part of the material mixing box 1 is connected to the missing rack 36. The missing rack 36 and the rotating gear 35 are engaged. During the downward movement of the falling frame 17 driving the falling frame 3, the rotating member 34 intermittently squeezes the pressure rod 33 under the cooperation of the rotating gear 35 and the missing rack 36, thereby driving the falling frame 3 to move up and down.

[0039] When the lower pressing frame 17 drives the falling frame 3 to move downward, it also drives the guide member 37, the pressure rod 33, the rotating member 34 and the rotating gear 35 to move downward. When the rotating gear 35 is engaged with the missing rack 36, the rotating gear 35 is driven to rotate. The rotation of the rotating gear 35 drives the rotating member 34 to rotate. When the rotating member 34 contacts the upper part of the pressure rod 33, the pressure rod 33 is driven to move upward. The pressure rod 33 drives the falling frame 3 to move upward. The reset spring 31 is compressed. When the rotating member 34 and the pressure rod 33 are engaged, the pressure rod 33 is driven upward. When the upper part of 3 is separated, under the action of the reset spring 31, the scatter frame 3 and the pressure rod 33 are driven to move downward and reset. Repeating the above operation can make the scatter frame 3 move up and down continuously. After the lower pressing frame 17 drives the scatter frame 3 to be inserted into the rice, the scatter frame 3 moves up and down continuously to scatter the rice clumps, which can facilitate the uniform feeding of rice. When the lower pressing frame 17 drives the scatter frame 3 to move upward and reset, it further drives the guide member 37, the pressure rod 33, the rotating member 34 and the rotating gear 35 to move upward and reset.

[0040] like Figure 8As shown, it also includes an anti-blocking mechanism to prevent the feed port from being blocked. The anti-blocking mechanism is arranged on the support frame 11 on the left, and the anti-blocking mechanism includes a loosening frame 4, a connecting circular frame 41 and a guide frame 42. The right part of the left support frame 11 is connected to the guide frame 42, and the bottom of the material mixing box 1 is slidably connected to the loosening frame 4, and the left part of the loosening frame 4 is connected to the connecting circular frame 41. The connecting circular frame 41 and the guide frame 42 are slidably connected.

[0041] When the material leveling box 1 moves left and right, it will drive the loosening frame 4 and the connecting circular frame 41 to move left and right as well. The connecting circular frame 41 moves left and right on the guide frame 42. Under the action of the guide frame 42, the connecting circular frame 41 is driven to move up and down continuously. The up and down movement of the connecting circular frame 41 also drives the loosening frame 4 to move up and down continuously. The loosening frame 4 can be continuously inserted into the feed port by continuously moving up and down, so that the loosening frame 4 can dredge the rice in the feed port to prevent the rice from blocking the feed port, thereby further achieving uniform feeding.

[0042] like Figures 9-11 As shown, it also includes a screed mechanism for evenly pouring rice into the screed box 1, the screed mechanism includes a storage hopper 53, a second slider 54, a guide rail 56, a feed pipe 55 and a driving assembly, the front upper part of the screed box 1 is slidably connected to the second slider 54, the second slider 54 is slidably connected to the guide rail 56, the bottom of the guide rail 56 is connected to the storage hopper 53, the storage hopper 53 is internally connected to the feed pipe 55, and a plurality of equidistantly distributed feed ports are evenly arranged at the bottom of the feed pipe 55, and the equidistantly distributed feed ports can In order to make the rice more evenly spread inside the material mixing box 1, a driving component for driving the storage bucket 53 to move left and right is provided between the upper part of the right support frame 11 and the second slider 54; the driving component includes a fixing part 5, an electric push rod 51 and a first slider 52, the lower part of the guide rail 56 is slidingly connected to the first slider 52, the front upper part of the right support frame 11 is connected to the fixing part 5, the upper part of the fixing part 5 is connected to the electric push rod 51, and the left part of the telescopic rod of the electric push rod 51 is connected to the first slider 52.

[0043] Before pouring the rice into the screed box 1, the front part of the feeding pipe 55 can be connected to the external feeding pipe first, and then the storage bucket 53 can be manually moved backward to drive the feeding pipe 55 to move above the screed box 1. Then the telescopic rod of the electric push rod 51 is controlled to extend and retract to drive the first slider 52 to move left and right. The left and right movement of the first slider 52 drives the guide rail 56, the storage bucket 53 and the feeding pipe 55 to move left and right, so that the rice is evenly spread into the screed box 1 through the feeding pipe 55. This can avoid the situation where people pour rice at one time and cause rice accumulation. The rice is spread into the screed box 1 by moving the feeding pipe 55 left and right, further achieving uniform feeding. After the pouring is completed, the electric push rod 51 is closed, and the guide rail 56 and the feeding pipe 55 are manually pulled forward to reset, and the feeding pipe 55 and the external feeding pipe are disconnected.

[0044] like Figure 12 As shown, a limiting mechanism is also included, which is arranged between the guide rail 56 and the second slider 54. The limiting mechanism includes a connecting plate 6, a limiting spring 61, a limiting member 62 and a limiting slot block 63. The front of the second slider 54 is connected to the connecting plate 6, and the front of the connecting plate 6 is slidingly connected to the limiting member 62. The limiting spring 61 is connected between the upper part of the limiting member 62 and the connecting plate 6. The front of the guide rail 56 is connected to the limiting slot block 63, and the limiting slot block 63 and the limiting member 62 are squeezed together. After the guide rail 56 drives the limiting slot block 63 to move backward to the bottom of the limiting member 62, the limiting member 62 is stuck in the limiting slot block 63 to limit the guide rail 56.

[0045] Initially, the limiting spring 61 is in a stretched state. When the guide rail 56 drives the limiting slot block 63 to move backward to below the limiting member 62, the limiting spring 61 drives the limiting member 62 to move downward and get stuck in the limiting slot block 63. Through the cooperation between the limiting slot block 63 and the limiting member 62, the position of the guide rail 56 can be locked, and the position of the feeding pipe 55 can be locked at the same time, to prevent the feeding pipe 55 from being displaced forward and backward during the process of moving left and right to spread the material, thereby affecting the spreading of the material. If the feeding pipe 55 has finished spreading the rice, the limiting member 62 can be manually moved upward and disengaged from the limiting slot block 63, and the limiting spring 61 is stretched, so that the guide rail 56 can be pulled forward and reset.
