on this basis, the screening mechanism 300 further includes a preferred barrel 320 and a driving member 340, a driving end of the driving member 340 is connected to the preferred barrel 320 and the primary screen barrel 311, and is configured to drive the preferred barrel 320 and the primary screen barrel 311 to rotate, and set the preferred barrel 320 at the bottom of the primary screen barrel 311, and the bottom of the inner cavity 312A is in a hollow state, please refer to fig. 8, the hollow part is sealed by a lattice stopper 314 disposed at the bottom of the primary screen barrel 311, and the organic fertilizer in the inner cavity 312A can fall into the preferred barrel 320 after the hollow part is opened.
The working principle is as follows:
the primary screen barrel 311 is driven to rotate by the driving member 340, the rotation process is divided into the following stages, firstly, when the temperature in the heated space does not reach 45-50 ℃, the water in the organic fertilizer is not dried, the organic fertilizer does not expand (meaning the organic fertilizer can normally flow in the centrifugal groove 3121), because the rotation of the primary screen barrel 311 can generate a centrifugal force effect, under the same environment, the centrifugal force is related to the weight of the organic fertilizer, that is, the organic fertilizer with more moisture is subjected to the centrifugal force and is larger than the organic fertilizer with less moisture in the rotating process, therefore, the organic fertilizer with high moisture content can escape to the periphery under the action of centrifugal force, so that the moisture content of the peripheral organic fertilizer (the organic fertilizer in the outer cavity 311A) is greater than that of the inner organic fertilizer (the organic fertilizer in the inner cavity 312A), and the peripheral organic fertilizer and the inner organic fertilizer are isolated by the spacer ring 312; secondly, when the temperature in the heating space reaches 45-50 ℃, because the organic fertilizer in the inner cavity 312A contains almost no water (no water needs to be evaporated), so that the organic fertilizer in the inner cavity 312A is heated and expanded, and the top of the spacer ring 312 is provided with a barrel cover 313, the top of the spacer ring 312 is sealed by the barrel cover 313, and the centrifugal groove 3121 is blocked along with the expansion of the organic fertilizer, therefore, the inner cavity 312A is in a closed state, the continued expanded organic fertilizer can push the barrier 314 open, at this time, the organic fertilizer in the inner cavity 312A can fall into the preferred barrel 320, the organic fertilizer with more moisture content is separated from the organic fertilizer with less moisture content at the temperature node of 45-50 ℃, then independently drying the organic fertilizers with different moisture contents to avoid the influence of bad fertilizers (organic fertilizers with more moisture contents) on other organic fertilizers;
in addition, the primary screening barrel 311 and the preferential barrel 320 can rotate under the driving of the driving part 340, so that organic fertilizers are mixed in independent spaces where the organic fertilizers are located, and heat conduction is facilitated; and hot-air can carry out the upstream, so the temperature of top will be higher than the bottom in the heated space, lies in the higher fertilizer of moisture content can fully evaporate moisture in prescreening bucket 311 after the separation like this, and the less fertilizer of bottom moisture content also can avoid overheating impaired.
In a second embodiment, referring to fig. 4, an outer edge of the barrel cover 313 extends outward, the outer edge of the extended barrel cover 313 is connected to a top edge of the primary screening barrel 311, and the height of the spacer ring 312 is lower than the height of the primary screening barrel 311, so that an inwardly concave groove (i.e. a groove) is formed at the top of the barrel cover 313 to provide a feeding space for organic fertilizer, i.e. organic fertilizer is stacked on the top of the barrel cover 313 during feeding, then a plurality of feeding ports 3131 are formed at a position of the top wall of the barrel cover 313 on the periphery of the spacer ring 312, organic fertilizer enters the primary screening barrel 311 through the feeding port 3131 under the action of centrifugal force when the primary screening barrel 311 rotates, thereby feeding organic fertilizer, so that the organic fertilizer is not directly poured into the primary screening barrel 311, if the organic fertilizer is directly poured into the primary screening barrel 311, the organic fertilizer is stacked, and is difficult to be effectively separated during the rotation, but the organic fertilizer is gradually fed into the primary screening barrel 311 through the feeding port 3131 by the centrifugal force after being stacked on the barrel cover 313, can solve directly piling up in prescreening bucket 311 like this and cause the problem that the fertilizer can not effectively separate.
In the third embodiment, considering that the organic fertilizer in the preferred barrel 320 is also divided into good and bad organic fertilizers, because the organic fertilizer may be bonded in the above process, once the organic fertilizer is bonded, the quality of later-period fertilizer spreading may be affected, for this reason, the bottom plate of the preferred barrel 320 is a vibration plate, and the bonded organic fertilizer falling into the preferred barrel 320 is separated by vibration of the vibration plate.
However, because the organic fertilizer is bonded by centrifugal extrusion and can be separated by vibration, if the organic fertilizer can not be separated by the self-bonding vibration, the organic fertilizer needs to be optimized (i.e. more dispersed organic fertilizer is selected), as shown in fig. 3 and 12, the top of the optimized barrel 320 is provided with the receiving hopper 330, the radius of the receiving hopper 330 is larger than that of the optimized barrel 320, so that a receiving groove 330A for receiving the organic fertilizer is formed at the periphery of the optimized barrel 320, as shown in fig. 6, a plurality of optimized grooves 3211 are arranged on the outer side wall of the optimized barrel 320 near the top, so that the organic fertilizer in the optimized barrel 320 is bounced by the vibration force, and under the gravity, the bounced height of the bonded organic fertilizer is lower than that of the dispersed organic fertilizer, and then under the action of the centrifugal force, the dispersed organic fertilizer can fly out through the optimized grooves 3211 (because the height of the dispersed organic fertilizer is matched with the optimized grooves 3211, the bonded organic fertilizer is blocked by the inner wall of the optimal barrel 320 due to low height), and falls into the receiving groove 330A after flying out, so that the dispersed organic fertilizer is selected.
It is worth to say that the sizes of particles formed in the processing process of the organic fertilizer are similar, so the weight difference between the bonded organic fertilizer and the dispersed organic fertilizer is obvious.
