[0007] In the drying device, the compound fertilizer is effectively prevented from piling up at the bottom and is dried evenly.
[0008] As a further improvement of the present application, the filter is formed by splicing a plurality of segments, and the filter is spiral-shaped as a whole.
[0009] As a further improvement of the present application, a clamping plate is fixedly connected to one end of the filter screen that fits the shaft sleeve, and a clamping block is fixedly connected to the bottom end of the clamping plate at equal distances.

When the drying device body is used to dry the compound fertilizer, the heating mechanism can be turned on to heat the drying device body, and then the motor is turned on to drive the spiral rod, and then the compound fertilizer is transported into the drying device body through the feed port, so that the compound fertilizer falls on the filter screen, and the mesh of the filter screen is smaller than the size of the compound fertilizer, so that the compound fertilizer can stay on the filter screen without affecting the heating and drying of the compound fertilizer, and gradually falls to the bottom of the drying device body along the spiral slope. At the same time, the spiral rod drives the turntable to rotate, so that the rope is pulled up and down with the rotation cycle of the turntable, so that the steel ball collides with the bottom of the filter screen, and the compound fertilizer staying on the filter screen can be shaken off to the bottom of the drying device body. The compound fertilizer that falls to the bottom enters the shaft sleeve from the feed trough, is transported to the top of the shaft sleeve by the spiral rod, and falls on the filter screen to flow slowly again, so that a small amount of compound fertilizer stays layer by layer, and the heating and drying time is increased, so as to effectively avoid the accumulation of compound fertilizer at the bottom and achieve the effect of uniform drying.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.
[0025] The first implementation method:
[0026] Figure 1-4 A drying device for compound fertilizer processing is shown, comprising a drying device body 1 with a barrel cover installed on the top, a feed port 5 is drilled on the top of the barrel cover, a heating mechanism 9 is installed on the inner wall of the drying device body 1, four supporting legs 2 are fixedly connected to the bottom of the drying device body 1, a support plate 3 is fixedly connected between the four supporting legs 2, a motor 4 is fixedly connected to the top of the support plate 3, a screw rod 7 is connected to the output end of the motor 4, a sleeve 6 is provided on the outer sleeve of the screw rod 7, and the bottom end of the sleeve 6 is fixedly connected to the bottom of the drying device body 1, and the bottom of the sleeve 6 A feed trough 12 is symmetrically opened on the side wall, a filter screen 8 is detachably connected to the outer surface of the screw rod 7, a turntable 14 is threadedly connected to the top of the screw rod 7, and protrusions 15 with arc-shaped clamping rings on the top are symmetrically fixedly connected on both sides of the top of the turntable 14, and the two protrusions 15 are designed to be one high and one low. Vertically corresponding through holes 13 are opened on each layer of the filter screen 8, a rope 10 is passed through the through holes 13, and one end of the rope 10 is bound to the clamping ring on the top of the protrusion 15, and steel balls 11 are equidistantly passed through the rope 10, and the steel balls 11 are located under each layer of the filter screen 8.
[0027] This solution can be achieved. When the drying device body 1 is used to dry the compound fertilizer, the heating mechanism 9 can be turned on to heat the drying device body 1, and then the motor 4 is turned on to drive the screw rod 7, and then the compound fertilizer is transported to the drying device body 1 through the feed port 5, so that the compound fertilizer falls on the filter screen 8, and the mesh of the filter screen 8 is smaller than the size of the compound fertilizer, which is convenient for the compound fertilizer to stay on the filter screen 8, and at the same time does not affect the heating and drying of the compound fertilizer, and gradually falls to the bottom of the drying device body 1 along the spiral slope. At the same time, the screw rod 7 drives the turntable 14 to rotate, so that the rope 10 is pulled up and down with the rotation cycle of the turntable 14, so that the steel ball 11 collides with the bottom of the filter screen 8, and the compound fertilizer staying on the filter screen 8 can be shaken off to the bottom of the drying device body 1, and the compound fertilizer falling to the bottom enters the sleeve 6 from the feed trough 12, and is transported to the top of the sleeve 6 through the screw rod 7 and falls on the filter screen 8 to flow slowly again, so that a small amount of compound fertilizer stays layer by layer, and the heating and drying time is increased, which effectively avoids the accumulation of compound fertilizer at the bottom and achieves the effect of uniform drying.
[0028] The second implementation method:
[0029] Figure 2 and Figure 5-7It is shown that the filter screen 8 is composed of multiple segmented splicings, and the filter screen 8 is spiral as a whole. The end of the filter screen 8 that fits the shaft sleeve 6 is fixedly connected with a card plate, and the bottom end of the card plate is fixedly connected with a card block 16 at an equal distance. The outer wall of the shaft sleeve 6 is cut with a groove 17 corresponding to the card block 16, and the inner wall of the groove 17 is rotatably connected with a force plate 18, and the force plate 18 is engaged with the groove 17. A card groove 19 corresponding to the card block 16 is cut on the force plate 18, and the force plate 18 is engaged with the card block 16. The bottom of the steel ball 11 is fixedly connected to it by a rope 10 tied in a round shape, and the diameter of the round ball is greater than twice the diameter of the perforation 13. The diameter of the turntable 14 is equal to half the diameter of the drying device body 1, and the feed port 5 is offset from the turntable 14.
[0030] This solution can achieve that when the internal filter screen 8, rope 10, and steel ball 11 are damaged after drying the compound fertilizer for a long time, the barrel cover can be opened to remove the turntable 14 from the screw rod 7, and then the filter screen 8 can be pulled out from the surface of the sleeve 6 in sections. After each layer of the filter screen 8 is pulled out, the force plate 18 at the bottom can be rotated and inserted into the groove 17 to facilitate the removal of the filter screen 8 below, and then the connection on the steel ball 11 is opened to take out the steel ball 11, and then the filter screen 8 of the next layer is taken out, and the filter screen 8 of the next layer is taken out. After a cycle, all the ropes 10, steel balls 11 and filter screens 8 are removed for replacement. Before installation, the force plate 18 is opened from the groove 17, and the ropes 10 are passed through the perforations 13, and a new layer of filter screen 8 is sleeved on the surface of the shaft sleeve 6 so that the block 16 at the bottom is inserted into the slot 19, thereby positioning the filter screen 8, and then the ropes 10 are knotted and the steel balls 11 are sleeved on top, and the steel balls 11 are limited by the round knot, and they are assembled in sequence, thereby achieving the effect of replacing the internal parts of the drying device body 1.
[0031] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
