A servo motor 10 is installed on the lower part of the outer right side of the processing box 1 by bolt connection, and the output shaft of the servo motor 10 is fixedly connected to the right end of the driving shaft 101.

[0032] The trigger assembly includes a positioning frame 11, a driven gear 111, a missing gear 112, a trigger rod 113, a positioning seat 114, a limit plate 115, a return spring I 116, a return spring II 117 and a trigger frame 118. Figure 5 and Figure 6As shown, a positioning frame 11 is slidably connected to the upper left side of the processing box 1, and a straight hole is opened at the lower part of the positioning frame 11. The front side of the lower part of the positioning frame 11 is fixedly connected to a limiting plate 115, and the limiting plate 115 is slidably connected to the left side of the processing box 1. The front side of the lower part of the limiting plate 115 is an inclined surface. When the limiting plate 115 moves downward and contacts the material blocking plate 5, the limiting plate 115 can drive the material blocking plate 5 to move forward. Three return springs II 117 are evenly spaced and connected to the lower front side of the outer front side of the processing box 1. The left end of the spaced feed pipe 4 is fixedly sleeved with a positioning seat 114, and a column is fixed to the rear side of the left side of the positioning seat 114. A return spring I 116 is connected between the rear side of the positioning seat 114 and the lower part of the left side of the feed frame 3. The rear side of the positioning frame 11 is fixedly connected to the trigger rod 11 3. The top of the trigger rod 113 contacts the column of the positioning seat 114. When the trigger rod 113 moves upward, the trigger rod 113 can drive the positioning seat 114 to swing upward. The lower left side of the processing box 1 is rotatably connected to the driven gear 111. The left end of the shaft of the driven gear 111 is fixed with a trigger frame 118. A protrusion is provided on the left side of the trigger frame 118. The protrusion of the trigger frame 118 is located in the slotted hole of the positioning frame 11. When the trigger frame 118 rotates, the trigger frame 118 can drive the positioning frame 11 to move. The lower left side of the outer side of the processing box 1 is rotatably connected to the missing gear 112. The missing gear 112 is located above the drive shaft 101. The missing gear 112 rotates and engages with the driven gear 111. The right side of the shaft of the missing gear 112 and the left side of the drive shaft 101 are driven by a synchronous belt assembly.

[0033] First, place the collection container just below the processing box 1, pour an appropriate amount of selenium-rich rice into the feed frame 3, block the selenium-rich rice with the interval feed pipe 4, then connect the hot air pipe 22 to the machine for exhausting hot air, start the machine to exhaust the hot air into the hot air pipe 22, and the hot air pipe 22 sprays the hot air into the processing box 1, and at the same time start the servo motor 10 to reverse and drive the drive shaft 101 to rotate forward, and the drive shaft 101 rotates forward to drive the stirring frame 102 to rotate forward, and the drive shaft 101 rotates forward and also drives the missing gear 112 to rotate forward. When the missing gear 112 rotates forward and engages with the driven gear 111, the missing gear 112 drives the driven gear 111 to reverse 120 degrees, and the driven gear 111 reverses and drives the trigger frame 118 to reverse, and the trigger frame 118 reverses and drives the positioning frame 11 to move downward, and the positioning frame 1 1 moves downward, driving the trigger rod 113 and the limit plate 115 to move downward, and the limit plate 115 moves downward to contact the material blocking plate 5, and the limit plate 115 drives the material blocking plate 5 to move forward without sealing the processing box 1, and the reset spring II 117 is stretched. At this time, the missing gear 112 rotates forward and disengages from the driven gear 111, and the driven gear 111 stops reversing, and the limit plate 115 stops driving the material blocking plate 5 to continue moving forward. When the missing gear 112 continues to rotate forward and engages with the driven gear 111 again, the missing gear 112 drives the driven gear 111 to reverse 120 degrees again, and the trigger frame 118 reverses again to drive the positioning frame 11 to move upward, and the positioning frame 11 moves upward to drive the limit plate 115 and the trigger rod 113 to move upward, and the limit plate 1 15 moves upward and disengages from the material blocking plate 5. Due to the action of the reset spring II 117, the material blocking plate 5 moves backward and resets. When the trigger rod 113 moves upward and contacts the positioning seat 114, the trigger rod 113 drives the positioning seat 114 to swing upward, the reset spring I 116 is compressed, and the positioning seat 114 swings upward to drive the interval feed pipe 4 to reverse ninety degrees. The interval feed pipe 4 stops blocking the selenium-rich rice in the feed frame 3, and an appropriate amount of selenium-rich rice is discharged into the processing box 1 through the interval feed pipe 4. The selenium-rich rice contacts the sieve plate 7, and the sieve plate 7 filters out the large debris in the selenium-rich rice. Since the sieve plate 7 is inclined, the filtered large debris slides into the discharge frame 8 and is blocked by the baffle plate 9, and the selenium-rich rice that has filtered out the large debris passes through the sieve plate 7 and falls To the guide plate 21, since the two sides of the guide plate 21 are inclined and in an inverted V shape, the selenium-rich rice can be guided to both sides to contact the stirring frame 102 evenly, and the hot air in the processing box 1 dries the selenium-rich rice. At the same time, the stirring frame 102 rotates forward to stir the selenium-rich rice, so that the selenium-rich rice is fully in contact with the hot air and is quickly dried, thereby improving the drying efficiency. When the missing gear 112 is engaged with the driven gear 111 again, the trigger frame 118 is reversed 120 degrees again, and the trigger frame 118 drives the positioning frame 11 to move downward and reset. The positioning frame 11 resets and drives the limit plate 115 and the trigger rod 113 to move downward and reset. The trigger rod 113 resets without limiting the positioning seat 114. Due to the action of the reset spring Ⅰ116,The positioning seat 114 swings downward to reset, driving the interval feed pipe 4 to rotate forward 90 degrees to reset. The interval feed pipe 4 blocks the remaining selenium-rich rice in the feed frame 3. At this time, the selenium-rich rice in the processing box 1 continues to be dried. When the missing gear 112 engages with the driven gear 111 again, the limit plate 115 drives the material blocking plate 5 to move forward and open, and the selenium-rich rice in the processing box 1 falls from the processing box 1 to the collection container and is collected. This is repeated to complete the intermittent feeding, drying and discharging work process. When all the selenium-rich rice is dried, stop discharging the hot air into the hot air pipe 22, turn off the servo motor 10, stop driving the stirring frame 102 to rotate forward, and stop driving the missing gear 112 to rotate forward through the synchronous belt assembly. The trigger rod 113 and the limit plate 115 also stop moving. The collection container is picked up to carry out subsequent processing of the dried selenium-rich rice, and another collection container is placed under the discharge frame 8. The force-bearing rod 91 is pulled to drive the shielding plate 9 to swing downward and open. The large debris in the discharge frame 8 falls into the collection container, and then the force-bearing rod 91 is pulled to drive the shielding plate 9 to swing upward and reset. Example 2

[0034] On the basis of embodiment 1, a vibration assembly is also included. The vibration assembly includes a guide tube 12, a cam 121, a positioning plate 122, a pull wire 123 and a compression spring 124. Figure 7 As shown, a conduit 12 is fixedly connected symmetrically on the front and back right side of the processing box 1, and a positioning plate 122 is slidably connected to the lower part of the outer right side of the processing box 1. A pull wire 123 is symmetrically connected to the bottom of the positioning plate 122. The tail ends of the pull wires 123 on the front and rear sides pass through the conduits 12 on the front and rear sides and are fixedly connected to the right side of the sieve plate 7. The pull wire 123 slides downward along the conduit 12, thereby driving the sieve plate 7 to move. A compression spring 124 is symmetrically connected between the right side of the sieve plate 7 and the right side of the positioning frame 6. A cam 121 is fixedly sleeved on the right side of the drive shaft 101, and the cam 121 is in contact with the positioning plate 122. When the cam 121 rotates, the cam 121 can drive the positioning plate 122 to move downward.

[0035] When the servo motor 10 starts to rotate forward, the drive shaft 101 rotates forward and also drives the cam 121 to rotate forward. When the cam 121 rotates forward so that the convex end contacts the positioning plate 122, the cam 121 drives the positioning plate 122 to move downward. The positioning plate 122 moves downward and drives the pull wire 123 to move downward. The pull wire 123 moves downward through the conduit 12 and drives the sieve plate 7 to move to the right. The compression spring 124 is compressed. When the cam 121 continues to rotate forward so that the convex end is out of contact with the positioning plate 122, the cam 121 stops contacting the positioning plate. 122 is limited, and due to the action of compression spring 124, sieve plate 7 moves to the left and resets. This is repeated. As cam 121 continuously rotates forward, sieve plate 7 also continuously moves left and right. When selenium-rich rice falls onto sieve plate 7, sieve plate 7 moves left and right to vibrate and screen the selenium-rich rice, screening out large debris in the selenium-rich rice. When servo motor 10 is turned off, drive shaft 101 stops driving cam 121 to rotate forward, cam 121 stops driving positioning plate 122 to move, and sieve plate 7 also stops moving left and right. In this way, selenium-rich rice can be prevented from getting stuck on sieve plate 7 and affecting screening, thereby improving the effect of screening large debris from selenium-rich rice. Example 3

[0036] On the basis of embodiment 1 and embodiment 2, it also includes a mounting frame 13 and a cloth cover 14, see Figure 8 As shown, the discharge end of the processing box 1 is fixedly connected to a mounting frame 13, and the bottom of the mounting frame 13 is fixedly connected to a cloth cover 14. When the selenium-rich rice is discharged into the cloth cover 14, the cloth cover 14 can block the flying dust.

[0037] Also includes a cover plate 15, see Figure 8 As shown, a cover plate 15 is rotatably connected to the left side of the top of the feed frame 3.

[0038] Also includes an observation window 16, see Figure 8 As shown, observation windows 16 are fixedly connected to the lower parts of the front and rear sides of the processing box 1.

[0039] When the dried selenium-rich rice is discharged from the processing box 1, the selenium-rich rice is discharged into the cloth cover 14. The selenium-rich rice in the cloth cover 14 falls accurately into the collection container. The cloth cover 14 blocks the dust generated during the falling process of the selenium-rich rice, thereby preventing the dust from floating around and affecting the environment, thereby ensuring the cleanliness of the surrounding environment.

[0040] When it is time to pour selenium-enriched rice into the feed frame 3, the cover 15 is first pulled upward to swing open, then an appropriate amount of selenium-enriched rice is poured into the feed frame 3, and then the cover 15 is pulled downward to swing close. This prevents foreign matter from falling into the feed frame 3 and contaminating the selenium-enriched rice, thereby ensuring the quality of the selenium-enriched rice.

[0041] When the stirring rack rotates forward to stir and dry the selenium-rich rice by hot air, the operator can check the drying condition of the selenium-rich rice through the observation window 16. In this way, the drying condition of the selenium-rich rice can be checked in time, thereby being able to make corresponding operations according to the situation of the selenium-rich rice in time.

[0042] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in this field based on the above content of the present invention are all within the scope of protection required by the present invention.
