GRAVITY COMPENSATION SWING TYPE VEGETABLE SEED SCREENING
AND DRYING DEVICE
TECHNICAL FIELD

BACKGROUND
With the development of agricultural economy, large-scale vegetable planting is becoming more and more popular. Before planting, vegetable seeds need to be dried and screened to improve the germination rate. However, the existing vegetable seed screening and drying devices still have the following problems.
Firstly, when a large number of vegetable seeds are dried, the seeds need to be dried in a large drying device, but the evaporated water tends to accumulate in the device and difficult to remove, so there is more and more accumulated water in the device, not only seriously affecting the drying effect, but also easily leading to rust of iron parts in the device; besides, the generated rust tends to adhere to vegetable seeds, thus reducing the quality of vegetable seeds.
Secondly, when vegetable seeds are being screened and dried, the device needs to keep moving to improve the efficiency of screening and drying. Under the influence of high-frequency vibration, the movement speed of vegetable seeds increases constantly. When rotating and drying, the seeds make free-fall movement inside the device. When the seeds fall into the discharge port after screening, some seeds are prone to show oblique throwing movement. At this time, if the seeds move too fast, they will hit the inner wall of the device, causing a large number of vegetable seeds to be damaged, and the long-term impact will also easily lead to the deformation of the plate wall of the device.
Therefore, a vegetable seed screening and drying device is urgently needed to solve the problems mentioned above.

The invention provides a low-cost, lossless gravity compensation swing type vegetable seed screening and drying device, and it has the following beneficial effects.
Firstly, when vegetable seeds fall freely inside the rotary drying barrel, in order to prevent the seeds from falling too fast, based on the technical principle of weight compensation, the invention skillfully sets the lifting air holes on the top barrel wall of the rotary drying barrel, so that hot air blown out from the non-contact air holes enters the rotary drying barrel; this not only strengthens the drying of the seeds, but also reduces the falling speed of the seeds without direkt/503233 contact with the seeds, and prevents the seeds from being damaged when they hit the barrel wall of the rotary drying barrel too fast.
Secondly, in order to prevent vegetable seeds from violently colliding with the discharge funnel when they fall into the discharge funnel, based on the technical principle of prevention in advance, the invention skillfully sets the impact buffering soft plate in the discharge funnel, and utilizes the elasticity of the rubber spring block itself and the repulsive force between the swing magnet and the fixed magnet to provide a stable buffering force. Under the condition of high vibration speed of the screening plate, the vegetable seeds are effectively prevented from directly colliding with the discharge funnel, and the damage rate of the vegetable seeds is reduced.
Thirdly, The vegetable seeds are placed in the rotary drying barrel for rotary drying, so that the vegetable seeds scatter and fall when the rotary drying barrel rotates, greatly increasing the contact area between the vegetable seeds and the hot air flow, and preventing uneven drying. At the same time, the hot air flow formed by the convection drying fan also plays a certain buffering role, so as to prevent the vegetable seeds from being damaged due to the excessive initial speed when they fall into the feeding barrel.
Fourthly, during the rotation of the rotary drying barrel, the moisture attached to the vegetable seeds is directly discharged along the lifting air holes at the top of the invention after evaporation, and there is no need to set an additional water vapor collection device. Meanwhile, the accumulated water condensed in the rotary drying barrel is discharged by rotating the drain holes at the bottom of the drying barrel.
Fifth, the impact buffer curtain in the buffer feeding bin buffers and intercepts the vegetable seeds before they fall into the diversion guide bin after drying, so as to prevent the vegetable seeds from falling directly and colliding with the diversion plate in the diversion guide bin, and the impact buffer curtain also absorbs the residual moisture on the vegetable seeds.
Sixth, The diversion plate diverts the dried vegetable seeds, prevents the vegetable seeds from being concentrated in one part of the screening plate to cause blockage, and greatly improves the screening efficiency.
Seventh, after the top flip is opened, not only is the primary screening situation directly503233 observed, but also the residue left on the top screening plate is conveniently and quickly removed, being beneficial to the maintenance and overhaul of the device.
Eighth, when there are many vegetable seeds falling on the baffle, the diversion clamping plate conducts lateral diversion of the vegetable seeds, so as to prevent the vegetable seeds from being concentrated in a certain place at the bottom of the diversion clamping plate.
Ninth, vegetable seeds are finely classified according to grain size after four-stage screening, and this is conducive to the scientific and industrialized development of vegetable planting and ensures the scientific development of vegetables of the same quality.

Preferably, the support base plate 141 is provided with a central controller to assist the drying and screening of the device, and a model of central controller is STC12C6082.
When in use, the user first starts the convection drying fan 117. The hot air generated by the convection fan 117 enters the rotary drying barrel 113 through the air inlet barrel 116 and the feeding barrel 115. The internal temperature of the rotary drying barrel 113 is heated in advance, and then the rolling driving motor 132 is started. With the cooperation of the reducer 133, the rolling driving motor 132 drives the gear shaft 134 and the driving gear 136 to rotate, the driving gear 136 drives the external gear 137 to rotate, and the external gear 137 drives the rotary drying barrel 113 to rotate, and then the vegetable seeds are poured into the feeding funnel 111. The vegetable seeds enter the rotary drying barrel 113 after passing through the rotary connecting part I 112, and then the lifting drying fan 121 is started. The hot air generated by the lifting drying fan 121 enters the air guide cavity 124 through the air duct 122, then flows out of the non-contact air holes 125 above the air guide cavity 124, and enters the rotary drying barrel 113 through the lifting air holes 1111. At this time, the vegetable seeds in the rotary drying barrel 113 rotate together with the rotary drying barrel 113, and at the same time, the vegetable seeds also move towards the feeding barrel 115. After the vegetable seeds rotate to the top, they fall freely.
At this time, the vegetable seeds spread out, greatly increasing the contact area with hot air. The large hot air flowing from the lifting air holes 1111 not only strengthens the drying of the seeds,
but also reduces the falling speed of the seeds without directly contacting the seeds, so as t&J503233 prevent the seeds from being damaged when the falling speed is too fast and colliding with the wall of the rotary drying barrel 113. During the rotation of the rotary drying barrel 113, the moisture attached to the vegetable seeds evaporates and is directly discharged along the top lifting air holes 1111. After the vegetable seeds are dried, they fall into the buffer blanking bin 118 through the feeding barrel 115 and hit the impact buffer curtain 119. At this time, the impact buffer curtain 119 buffers and intercepts the vegetable seeds, so as to prevent the vegetable seeds from directly falling and colliding with the diversion plate 2191 in the diversion guide bin 219.
At the same time, the impact buffer curtain 119 also absorbs the residual moisture on the vegetable seeds. After being buffered by the impact buffer curtain 119, the vegetable seeds fall on the diversion plate 2191, and then fall on the top screening plate 217 through the diversion clamping plate 2193. After the starting of the swing driving motor 223, the swing driving motor 223 drives the cam shaft 224 and the swing cam 225 to rotate, and the swing cam 225 continuously pushes the pressure bearing plate 226 on the screening bin 212 when rotating. At this time, the screening bin 212 pushed back and forth reciprocates around the top of the hanging swinging arm 213, and the screening plates 217 in the screening bin 212 reciprocate together.
The vegetable seeds on the top screening plate 217 continuously move downward along the screening plates 217, and the seeds with small particle size gradually fall from the top screening plate 217 to the middle and bottom screening plates 217, until they finally fall into the corresponding feeding funnel 218. The vegetable seeds are collected by placing a container under the feeding funnel 218. At the same time, in order to prevent the vegetable seeds from violently colliding with the feeding funnel 218 when they fall into the feeding funnel 218, the invention skillfully sets the impact buffering soft plate 232 in the feeding funnel 218, and provides a stable buffering force by utilizing the elasticity of the rubber spring block 231 and the repulsive force between the swing magnet 233 and the fixed magnet 234. Under the condition that the vibration speed of the screening plate 217 is high, the vegetable seeds are effectively prevented from directly colliding with the discharge funnel 218, and the damage rate of the vegetable seeds is reduced. After the vegetable seeds are screened and dried, the device stops working, the internal temperature of the rotary drying barrel 113 gradually decreases, the residual water vapor inside is liquefied by cold, and the formed water flow flows out through the drain holes 1112 at the bottom of the rotary drying barrel 113, thus reducing the internal watet/503233 accumulation. Moreover, the top flip 216 arranged at the top of the screening bin 212 may be opened. After that, the primary screening situation in the screening bin 212 is directly observed, and the residues left on the top screening plate 217 are conveniently and quickly removed, being beneficial to the maintenance and overhaul of the device. The above is the overall working flow of the invention, and this step may be repeated the next time it is used.
