Referring to fig. 1-3, a controlled release fertilizer manufacturing apparatus comprises a workbench 1, a conveying turntable 2 is arranged on the workbench 1, and an agitator 3 is fixedly connected to the conveying turntable 2, so that the agitator 3 can rotate. Meanwhile, the outer wall of the stirring barrel 3 is wound with a heating wire 4 to heat the stirring barrel 3. The conveying turntable 2 can be connected with a driving motor to realize rotation.

Further, fixedly connected with support frame 5 on the workstation 1, vertical rotation is connected with stirring rake 6 on the support frame 5 to the lower tip of stirring rake 6 extends to the bottom of agitator 3. The support frame 5 is provided with a forward and reverse rotating motor 7 for driving the stirring paddle 6 to rotate.

When the controlled release fertilizer needs to be produced, fertilizer particles are put into the stirring barrel 3, and then the coating liquid is sprayed into the stirring barrel 3. At the moment, the stirring barrel 3 is driven to rotate through the conveying turntable 2, and meanwhile, the stirring paddle 6 is driven to rotate by the forward and reverse rotating motor 7.

When the rotation direction of the stirring paddle 6 is opposite to the rotation direction of the stirring barrel 3, fertilizer particles violently move under the action of the stirring paddle 6, so that the relative movement effect among the molecules is promoted. When the rotation direction of the stirring paddle 6 is the same as the rotation direction of the stirring barrel 3, the rotation speed of the forward and reverse rotating motor 7 is adjusted, so that the stirring paddle 6 and the stirring barrel 3 form a rotation speed difference, and then the stirring paddle 6 can still mix and stir the fertilizer particles.

The rotation direction of the stirring paddle 6 is frequently changed, so that the motion rule of fertilizer particles is broken, the contact chance of the fertilizer particles and the coating liquid is improved, the coating liquid can be uniformly coated on the surfaces of the fertilizer particles, the mixing and stirring efficiency and effect can be improved, the product quality can be improved, and the product quality can be further improved.

Further, carry fixedly connected with lifting machine 8 on the carousel 2, the feed end of lifting machine 8 communicates with the lower tip of agitator 3 to make the fertilizer granule in the agitator 3 can enter into in the lifting machine 8. Simultaneously, the discharge end of lifting machine 8 is located the top of agitator 3 to make fertilizer granule can flow back to in the agitator 3, thereby improve fertilizer granule's circulation flow effect, increase the contact chance of fertilizer granule and envelope liquid.

Further, fixed connection is provided with supporting box 9 and storage tank 10 on the workstation 1, and storage tank 10 is used for storing the envelope liquid to supporting box 9 and storage tank 10 are through feed liquor pipe 11 intercommunication, so that the envelope liquid in the storage tank 10 can enter into in the supporting box 9 through feed liquor pipe 11.

Furthermore, a drain pipe 12 is connected to the supporting box 9, the drain pipe 12 comprises a supporting pipe 13, a receiving pipe 14 and a discharge pipe 15 which are sequentially communicated from bottom to top, and the supporting pipe 13 is fixedly connected with the supporting box 9. Meanwhile, a bendable corrugated pipe 16 is fixedly connected to an end of the discharge pipe 15 away from the socket pipe 14, a nozzle 17 is fixedly connected to an end of the corrugated pipe 16 away from the socket pipe 14, and the corrugated pipe 16 and the nozzle 17 are respectively located at upper end positions inside the agitating barrel 3.

Further, a supporting shaft 18 is vertically and rotatably connected in the supporting box 9, and a plurality of fan blades 19 are fixed on the supporting shaft 18. Meanwhile, the lower end of the support shaft 18 extends to the outside of the support box 9 and is fixedly sleeved with a control gear 20, the conveying turntable 2 is fixedly sleeved with a control gear ring 21, and the control gear 20 is meshed with the control gear ring 21.

When the conveying turntable 2 drives the control gear ring 21 to rotate, the control gear ring 21 drives the control gear 20 to drive the support shaft 18 to rotate, and then the support shaft 18 drives the fan blades 19 to rotate, so that negative pressure is generated in the support box 9. At this time, the coating liquid in the storage box 10 enters the support box 9 through the liquid inlet pipe 11, then enters the nozzle 17 through the support pipe 13, the adapting pipe 14, the discharging pipe 15 and the corrugated pipe 16 in sequence, and is sprayed out through the nozzle 17, so that the automatic spraying operation of the coating liquid is realized. When the flow rate or flow of the coating liquid flowing through the discharge pipe 15 is different, the corrugated pipe 16 drives the nozzle 17 to swing, so that the spraying area of the coating liquid is increased, and the contact chance and the contact area of fertilizer particles and the coating liquid are further increased.

Further, the adapting pipe 14 is made of elastic materials such as rubber, silica gel or latex, a receiving block 22 is fixedly connected to the side wall of the support frame 5, an extrusion block 23 located right below the receiving block 22 is vertically and slidably connected to the side wall of the support frame 5, and the adapting pipe 14 is located between the receiving block 22 and the extrusion block 23. Meanwhile, the extrusion block 23 can press the bearing pipe 14 on the bearing block 22, so that the opening and closing of the bearing pipe 14 are controlled, and the workbench 1 is provided with an adjusting mechanism 24 for driving the extrusion block 23 to vertically move.

Further, the adjusting mechanism 24 comprises a plurality of adjusting balls 25 fixedly connected to the upper end of the stirring barrel 3, and the adjusting balls 25 are uniformly distributed along the circumferential direction of the stirring barrel 3. The adjusting ball 25 is located below the pressing block 23, and the adjusting ball 25 can abut against the lower end surface of the pressing block 23, so that the adjusting ball 25 can push the pressing block 23 to move upward.

When the stirring barrel 3 drives the plurality of adjusting balls 25 to rotate and the adjusting balls 25 are abutted to the lower end face of the extrusion block 23, the adjusting balls 25 can push the extrusion block 23 to move upwards along with the continuous rotation of the stirring barrel 3. At this time, the socket 14 is deformed by the pressing block 23 and the socket block 22, and blocks the coating solution.

When the adjusting ball 25 is separated from the extrusion block 23, the extrusion block 23 can move downwards and reset under the action of self gravity, and then the adapting pipe 14 resets under the action of self elasticity, so that the coating liquid enters the discharge pipe 15. The on-off control of the adapting pipe 14 can be realized by reciprocating in this way, and then the intermittent spraying operation of the coating liquid is realized.

When the extrusion block 23 and the bearing block 22 extrude and close the bearing pipe 14, the negative pressure value in the supporting box 9 is increased, and at the moment when the extrusion block 23 is reset, the coating liquid can be rapidly sprayed out, so that a part of the coating liquid can be instantly atomized, and the contact opportunity and the contact area of the coating liquid and fertilizer particles are increased. Meanwhile, when the coating liquid is sprayed out, the swing amplitude of the corrugated pipe 16 is increased, and the spraying area of the coating liquid is further increased, so that the coating liquid can be uniformly coated on the surfaces of the fertilizer particles, and the product quality is further improved.

The specific embodiments are only for explaining the present invention, and it is not intended to limit the present invention, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the present invention.
