[0002] Compound fertilizer refers to a fertilizer containing two or more nutrients of nitrogen, phosphorus and potassium. Compound fertilizer has the advantages of high nutrient content, few by-products and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable yields of crops.

[0003] At present, when the compound fertilizer granules are being rapidly molded, the staff will pour the prepared compound fertilizer materials into the processing equipment.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0021] In the traditional rapid forming operation of compound fertilizer granules, the compound fertilizer material is squeezed into a ball cake by using an extrusion die. During the extrusion process, a part of the compound fertilizer material will remain inside the groove of the extrusion die due to pressure. When the extrusion die is used to extrude the compound fertilizer material later, the ball cake cannot be squeezed out due to the blockage of the hole, and the compound fertilizer granule forming operation cannot be completed.

[0022] In view of this, the utility model provides a rapid forming device for compound fertilizer particles. The rapid forming device for compound fertilizer particles is used in combination with a cleaning device and an extrusion device to solve the problem that a part of the compound fertilizer material will remain in the groove of the extrusion die due to pressure, resulting in clogging of the holes and inability to extrude ball cakes. The cleaning device can be used to clean the compound fertilizer material retained in the holes of the extrusion device, thereby avoiding clogging of the holes of the extrusion device and inability to extrude ball cakes.

[0023] Embodiment 1: Figure 1 , 2 , 3 and 4 show that a compound fertilizer granule rapid prototyping equipment comprises a shell 1, the inner wall of the shell 1 is rotatably connected with a first cross bar 2 through a bearing, the outer wall of the first cross bar 2 is provided with a first gear 3, and the outer wall of the shell 1 is provided with a fixing plate 8, and the compound fertilizer granule rapid prototyping equipment also comprises: a cleaning device 4, which is arranged on one side of the shell 1; an extrusion device 5, which is installed above the first cross bar 2; a scattering device 6, which is arranged below the first cross bar 2; a drying device 7, which is installed below the inner part of the shell 1; a feeding port is processed on the top of the shell 1, and the material can be dropped into the inner part of the shell 1 through the feeding port, and when the extrusion device 5 rotates, it will drive the first gear 3 to rotate, and when the first gear 3 rotates, it will drive the scattering device 6 to rotate, and then when the extrusion device 5 rotates, the scattering device 6 will be driven by the extrusion device 5 to rotate; wherein, the cleaning device 4 can clean the extrusion device 5, the extrusion device 5 can extrude the compound fertilizer material into a cake, the scattering device 6 can break the cake-shaped compound fertilizer material into particles, and the drying device 7 can dry the compound fertilizer particles;

[0024] In the specific implementation process, it is worth pointing out that the top of the shell 1 is processed with a feed inlet, and the material can be dropped into the inside of the shell 1 through the feed inlet. When the extrusion device 5 rotates, it will drive the first gear 3 to rotate, and when the first gear 3 rotates, it will drive the scattering device 6 to rotate. Then, when the extrusion device 5 rotates, the scattering device 6 will be driven by the extrusion device 5 to rotate;

[0025] Specifically, when using the compound fertilizer granule rapid prototyping equipment, the worker first adds water and compound fertilizer materials in proportion for preparation, and then starts the extrusion device 5 through an external power supply. After the extrusion device 5 starts to rotate, the worker pours the prepared compound fertilizer material into the interior of the shell 1 from the feeding port at the top of the shell 1. During the falling process, the compound fertilizer material will first pass through the extrusion device 5. At this time, the compound fertilizer material will be squeezed into a ball cake by the extrusion device 5, until the ball cake breaks away from the extrusion device 5 and continues to fall, and then the ball cake is broken up into particles by the breaking device 6. Finally, these particles will fall to the bottom of the shell 1. After the worker dries the compound fertilizer particles through the drying device 7, all the compound fertilizer particles are taken out and the extrusion device 5 is cleaned using the cleaning device 4 to facilitate the next operation.

[0026] Embodiment 2: By Figure 1 and 2 It can be seen that the cleaning device 4 includes: a water tank 401, which is arranged on one side of the shell 1; a drain pipe 402, which is installed on the inner wall of the water tank 401 and is fixedly connected to the inner wall of the shell 1; a filter 403, which is arranged inside the water tank 401; a water inlet pipe 404, which is installed on the inner wall of the water tank 401 and is fixedly connected to the inner wall of the shell 1; a water pump 405, the model of the water pump 405 is: SG40-200, which is connected to the inner wall of the water inlet pipe 404 and is fixedly connected to the outer wall of the shell 1; a plurality of high-pressure nozzles 406 are provided and are evenly installed on the inner wall of the water inlet pipe 404; the outer wall of the water tank 401 A wall door is provided, through which workers can take out the materials collected at the bottom of the water tank 401 for unified processing, and the filter net 403 can filter the materials at the bottom of the water tank 401. When the water pump 405 extracts the water source inside the water tank 401, the filter net 403 can allow the water flow to pass normally, and block the materials to prevent the materials from entering the inside of the water pump 405 with the water flow, causing damage to the internal parts of the water pump 405; wherein, the water pump 405 can draw the water source inside the water tank 401 into the water inlet pipe 404 and then spray it out by the high-pressure nozzle 406 for cleaning operation, and the filter net 403 can filter the compound fertilizer particles;

[0027] In the specific implementation process, it is worth pointing out that the outer wall of the water tank 401 is provided with a wall door, through which workers can take out the materials collected at the bottom of the water tank 401 for unified treatment, and the filter 403 can filter the materials at the bottom of the water tank 401. When the water pump 405 extracts the water source inside the water tank 401, the filter 403 can allow the water flow to pass normally and block the materials, thereby preventing the materials from entering the interior of the water pump 405 with the water flow and damaging the internal parts of the water pump 405.

[0028] Specifically, on the basis of the above-mentioned embodiment 1, after the staff takes out the compound fertilizer particles, the materials retained in the holes of the extrusion device 5 can be cleaned through the cleaning device 4. First, the worker injects water into the water tank 401, and then turns on the water pump 405. After the water pump 405 is powered on, the water inside the water tank 401 will be drawn into the water inlet pipe 404. The water will be injected into the high-pressure nozzle 406 along the water inlet pipe 404, and finally, the materials retained in the holes of the extrusion device 5 will be cleaned by spraying through the high-pressure nozzle 406. After being impacted by the water flow, the retained materials will enter the bottom of the water tank 401 through the drain pipe 402, thereby completing the cleaning operation of the holes of the extrusion device 5.

[0029] Embodiment 3: By Figure 1 , 2 , 3 and 4 show that the extrusion device 5 includes: a first servo motor 501, the model of the first servo motor 501 is: ECMA-E1 1320RS, which is rotatably connected to the inner wall of the shell 1 through a bearing, and is detachably connected to the fixed plate 8; two second cross bars 502 are provided, both of which are rotatably connected to the inner wall of the shell 1 through a bearing, and the second cross bar 502 on the side close to the fixed plate 8 is detachably connected to the output end of the first servo motor 501; two second gears 503 are provided, which are respectively installed on the outer walls of the two second cross bars 502, and the second gear 503 on the side close to the fixed plate 8 is meshed and connected with the outer wall of the first gear 3; two first cross rollers 504 are provided, which are respectively installed on the outer walls of the two second cross bars 502, and both ends are in contact with the inner wall of the shell 1; two baffles 505 are provided, which are respectively installed on the outer walls of the two first cross rollers 504, and are both fixed to the inner wall of the shell 1; Two second gears 503 are provided and meshed with each other. When the second gear 503 close to the fixed plate 8 is rotated by force, the second gear 503 far from the fixed plate 8 is driven to rotate at the same time. The outer walls of the two first transverse rollers 504 are processed with a plurality of equidistant holes. When the compound fertilizer material passes through the two rotating first transverse rollers 504, it will be affected by the holes processed by the two first transverse rollers 504 and squeezed into a ball cake. The baffle 505 can limit the compound fertilizer material to fall to the bottom of the shell 1 only after being squeezed by the two first transverse rollers 504, so as to prevent the compound fertilizer material from falling to the bottom of the shell 1 without being squeezed. Among them, the first servo motor 501 can drive the second cross bar 502 to drive the first transverse roller 504 to rotate, and the second gear 503 can drive the first gear 3 to rotate when it is subjected to force.

[0030] In the specific implementation process, it is worth pointing out that two second gears 503 are provided and meshed with each other. When the second gear 503 close to the fixed plate 8 is rotated by force, the second gear 503 far from the fixed plate 8 is driven to rotate at the same time. The outer walls of the two first transverse rollers 504 are processed with a plurality of equidistant holes. When the compound fertilizer material passes through the two rotating first transverse rollers 504, it is affected by the holes processed by the two first transverse rollers 504 and is squeezed into a ball cake. The baffle 505 can limit the compound fertilizer material to fall to the bottom of the shell 1 only after being squeezed by the two first transverse rollers 504, so as to prevent the compound fertilizer material from falling to the bottom of the shell 1 without being squeezed.

[0031] Specifically, on the basis of the above-mentioned embodiment 1, when the staff performs the molding operation on the compound fertilizer particles, the first servo motor 501 is started by an external power supply. After the first servo motor 501 is powered on, it starts to drive the second cross bar 502 to rotate. When the second cross bar 502 rotates, it drives the second gear 503 to rotate. Because two second gears 503 are provided and are meshed and connected, when the second gear 503 close to the fixed plate 8 is rotated by force, it drives the second gear 503 away from the fixed plate 8 to rotate at the same time, so that the two second cross bars 502 can drive the two first cross rollers 504 to rotate to extrude the compound fertilizer.

[0032] Embodiment 4: By Figure 1 , 2 As can be seen from Figures 4 and 5, the disintegrating device 6 includes: a third crossbar 601, which is rotatably connected to the inner wall of the housing 1 through a bearing; a third gear 602, which is installed on the outer wall of the third crossbar 601 and meshed with the outer wall of the first gear 3; a second cross roller 603, which is installed on the outer wall of the third crossbar 601, and both ends are in contact with the inner wall of the housing 1; a plurality of saw teeth 604 are provided, and are equidistantly installed on the outer wall of the second cross roller 603; wherein, when the third gear 602 is subjected to force, the third crossbar 601 can be driven to drive the second cross roller 603 and the saw teeth 604 to rotate;

[0033] In the specific implementation process, it is worth pointing out that because the third gear 602 is meshed and connected with the first gear 3, and the first gear 3 is meshed and connected with the second gear 503 close to the fixed plate 8, when the extrusion device 5 performs the extrusion operation, the first gear 3 will drive the third gear 602 to rotate, and then the scattering device 6 can rotate to scatter the ball cakes;

[0034] Specifically, on the basis of the above-mentioned embodiment 1, when the compound fertilizer material is squeezed into a ball cake and separated from the extrusion device 5, the ball cake will be broken up into particles by the breaking device 6. The specific implementation method is that when the second gear 503 is rotated under force, it will drive the first gear 3 to rotate, and at the same time, the first gear 3 will drive the third gear 602 to rotate, so that the third gear 602 can drive the third cross bar 601 to rotate. At this time, the second cross roller 603 and the sawtooth 604 will be affected by the rotation of the third cross bar 601, so that the rotation can break up the ball cake into compound fertilizer particles.

[0035] Embodiment 5: By Figure 1 and 2 It can be seen that the drying device 7 includes: a second servo motor 701, the model of the second servo motor 701 is: ECMA-E1 1320RS, which is rotatably connected to the inner wall of the shell 1 through a bearing; a fourth cross bar 702, which is installed at the output end of the second servo motor 701 and is rotatably connected to the inner wall of the shell 1 through a bearing; a stirring plate 703, which is arranged on the outer wall of the fourth cross bar 702 and fits with the bottom of the shell 1; an electric heating tube 704, the model of the electric heating tube 704 is: KWS-1118, which is installed on the inner wall of the shell 1; the second servo motor 701 will slowly stir when driving the fourth cross bar 702 to drive the stirring plate 703 to rotate, so as to prevent the stirring plate 703 from rotating too fast and breaking the compound fertilizer particles. When all the compound fertilizer particles are heated, the workers can take out the compound fertilizer particles through the wall door provided in the shell 1; wherein, the second servo motor 701 can drive the fourth cross bar 702 to drive the stirring plate 703 to rotate, and the electric heating tube 704 can dry the compound fertilizer particles;

[0036] In the specific implementation process, it is worth pointing out that the second servo motor 701 will slowly stir when driving the fourth crossbar 702 to drive the stirring plate 703 to rotate, so as to prevent the stirring plate 703 from rotating too fast and breaking the compound fertilizer particles. When all the compound fertilizer particles are heated, the workers can take out the compound fertilizer particles through the wall door provided in the housing 1;

[0037] Specifically, on the basis of the above-mentioned embodiment 1, when the compound fertilizer is broken up into particles and falls to the bottom of the outer shell 1, the worker turns on the electric heating tube 704 for heating, and the heat is transferred to the compound fertilizer particles through the inner wall of the outer shell 1 to dry the compound fertilizer particles. At the same time, the worker starts the second servo motor 701 through an external power supply. After the second servo motor 701 is powered on, it starts to drive the fourth cross bar 702 to rotate. When the fourth cross bar 702 rotates, it drives the stirring plate 703 to stir the compound fertilizer particles. With the electric heating tube 704, all the compound fertilizer particles can be dried, thereby allowing the compound fertilizer particles to be quickly formed.
