Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production and processing equipment, and in particular to a dissolving powder spraying device used for fertilizer production. Background Art

[0002] With the continuous development of modern agriculture, fertilizers have effectively improved the production efficiency of crops and their scope of use has become increasingly wide.

[0003] In the process of agricultural sowing, a lot of granular fertilizers are used. Solid granular fertilizers are easy to spread and transport. In actual use, in order to ensure that the fertilizer's fertility continues to work effectively, the surface of the fertilizer is usually sprayed with powder during the fertilizer production process, so that the dissolved slow-release film raw material powder is effectively wrapped on the surface of the fertilizer to form a slow-release film, which is convenient for the fertilizer to continue to work effectively in the field.

[0004] However, when the fertilizer surface is powdered, since the fertilizer particles are mostly in a piled state, it is easy to cause uneven powdering, which affects the quality of the actual product. Therefore, we propose a dissolving powdering device for fertilizer production. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a dissolving powder spraying device for fertilizer production.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A dissolving powder spraying device for fertilizer production, comprising:

[0008] A base, wherein the top of the base is provided with a stepped groove;

[0009] The powder spraying and sorting mechanism is arranged at the top of the base through a support frame. The powder spraying and sorting mechanism includes an anastomotic ring. A flow guide mechanism is arranged at the top of the anastomotic ring. A plurality of spiral guide tubes are evenly arranged on the shell of the flow guide mechanism. The fertilizer particles are guided to give the fertilizer particles a tangential force for rotation, so as to ensure that the fertilizer can be rotated after being vacated. The powder spraying and sorting mechanism also includes a nozzle facing the spiral guide tube, which is used to spray the surface of the vacated fertilizer with a slow-release film raw material, and can also unload the vacated fertilizer particles under the action of the spraying air pressure, and realize the sorting operation of the fertilizer after the powder spraying according to the different landing points of the fertilizer caused by the final unloading.

[0010] The adjusting mechanism is located in the stepped groove of the base. The adjusting mechanism is provided with a forecast plate that is matched with the matching ring, and the forecast plate is rotatable, which is used to drive the fertilizer particles on the surface to rotate and provide centrifugal force to enable the waste to enter the spiral conduit, which is convenient for subsequent emptying operations. The adjusting mechanism also includes a receiving plate located above the forecast plate, which is used to receive the fertilizer particles after unloading, so that the sorted fertilizer falls on the surface of the receiving plate in an orderly and layered manner;

[0011] The material guide mechanism is installed on the upper part of one side of the base, and is used to export the sorted fertilizers in batches. The material guide mechanism is provided with a material guide plate and a material discharge port for exporting the fertilizers;

[0012] The feeding assembly is used for adding fertilizer raw materials, including an adjustable guide block to facilitate the delivery of fertilizer particles to different positions on the forecast plate.

[0013] As a preferred technical solution of the present application, the adjustment mechanism includes a push rod motor located at the bottom end of the stepped groove on the base, the top end of the output shaft of the push rod motor is coaxially connected to a lifting column, a support plate is fixedly installed on the middle part of the outer side of the lifting column to provide stable support, and a receiving plate is rotatably provided on the top end of the lifting column to receive the fertilizer after unloading;

[0014] A feed plate is sleeved on the middle part of the outer side of the lifting column, and a gear ring is provided at the bottom end of the feed plate at the perforation. A motor is installed on the top of the support plate, and a driving gear meshing with the gear ring is coaxially installed on the output shaft of the motor, thereby effectively realizing the rotation of the feed plate and providing centrifugal force for the subsequent rotation of the fertilizer and the subsequent evacuation of the fertilizer.

[0015] The sizes of the forecast plate and the receiving plate are consistent and are the same as the inner diameter of the anastomotic ring, so as to facilitate the blocking effect on the anastomotic ring and prevent the fertilizer particles from being scattered.

[0016] As a preferred technical solution of the present application, several groups of stabilizing rods are fixedly installed on the top of the support plate, and steel balls in contact with the bottom end of the prediction plate are fixedly installed on the top of the stabilizing rods, which are used to stably support the prediction plate while reducing the friction during the rotation of the prediction plate to ensure stable rotation.

[0017] As a preferred technical solution of the present application, the flow guide mechanism includes a cover shell, the top and bottom ends of the cover shell are both opened, and a plurality of groups of inlet ports are evenly arranged on the lower side of the inner wall of the cover shell for the entry of fertilizer particles that follow the rotation of the prediction plate to generate centrifugal force, and spiral conduits corresponding to the inlet ports are evenly arranged along the curvature of the shell body of the cover shell, and the spiral conduits are provided with a spiral curvature to facilitate the fertilizer particles that are drilled into the inlet ports by the centrifugal force and move along the spiral conduits to finally have a certain spiral effect, so that the fertilizer particles can finally rotate after being vacated at the top opening of the spiral conduit.

[0018] As a preferred technical solution of the present application, the powder spraying and sorting mechanism also includes a top plate installed on the top of the guide mechanism through a support rod, a storage hopper is provided on the top of the top plate for containing the slow-release film raw material, a pump body connected to the storage hopper is also installed on the top of the top plate, a conduit is connected to one end of the pump body, and a nozzle flush with the top opening of the spiral conduit is installed at the center of the bottom end of the top plate, the conduit is connected to the nozzle, so that the slow-release film raw material is effectively sprayed out and wrapped on the rotating and vacated fertilizer particles, and in this process, under the action of the air pressure sprayed by the nozzle, The kinetic energy of the fertilizer particles is gradually unloaded, so that the fertilizer particles are wrapped with the slow-release film and then fall onto the receiving plate. Due to the different weights of the fertilizer particles, the time for kinetic energy unloading is inconsistent, which leads to different final landing points of the fertilizer particles. The larger the particles and the larger the mass of the particles, the more time they consume, and the closer the landing point on the receiving plate is to the center of the circle. Conversely, the smaller the particles and the smaller the mass, the less time they consume, and the landing point is located on the receiving plate near the edge, thereby effectively realizing the slow-release film coating operation of the fertilizer particles and the sorting process.

[0019] As a preferred technical solution of the present application, the material guiding mechanism includes a fixed plate I, two sets of slide grooves are arranged at the top of the fixed plate I, and a pneumatic push rod I is installed in the slide groove, and a U-shaped slide is also slidably arranged in the slide groove of the fixed plate I, and the output shaft of the pneumatic push rod I is respectively connected to the two sets of support arms of the U-shaped slide, thereby driving the U-shaped slide to move;

[0020] An electric push rod is installed at the top of the U-shaped slide, and the output shaft of the electric push rod vertically penetrates the U-shaped slide downward and is connected to a guide plate. The side of the guide plate close to the powder spraying and sorting mechanism is curved. Under the action of the moving U-shaped slide, the guide plate moves to above the receiving plate. The setting of the electric push rod can prevent the guide plate from directly contacting the fertilizer on the surface of the receiving plate during movement, and then continue to probe and fall to the boundary line of sorting. The electric push rod is started to make the guide plate fall and contact with the fertilizer particles. The receiving plate is rotated, so that the sorted fertilizer is guided out under the action of the guide plate, and finally delivered to the discharge port along the guide plate to realize the collection of the fertilizer. This reciprocating process can realize the batch collection and processing of fertilizer particles of different particle sizes.

[0021] As a preferred technical solution of the present application, the feeding assembly includes a fixed plate II fixedly mounted on the side of the base, a slide is provided at the top of the fixed plate II, and a material guide block is slidably arranged on the slide, an inclined material discharge chute is provided on the material guide block, and a pneumatic push rod II for pushing the material guide block is provided on one side of the top of the fixed plate II, so that in actual use, the position of the material guide block extending into the prediction plate can be effectively adjusted to ensure that the fertilizer raw materials can fall evenly on the surface of the prediction plate.

[0022] The beneficial effects of the present invention are:

[0023] 1. Through the action of the rotating anticipation plate, the fertilizer particles are given centrifugal force. With the inlet on the guide mechanism and the setting of the spiral guide tube, the fertilizer particles are finally in a rotating posture when they are vacated, so that the sustained-release film raw material powder sprayed from the nozzle can be evenly wrapped on the surface of the waste particles, effectively improving the efficiency of powder spraying treatment;

[0024] 2. The kinetic energy of the fertilizer particles in the air is eliminated under the action of the nozzle, and the final fertilizer particles fall at different points on the receiving plate according to the actual particle size and weight, thereby effectively realizing that the fertilizer particles can be automatically sorted on the receiving plate surface in different ways after the powder spraying treatment, which provides convenience for subsequent batch collection;

[0025] 3. Through the setting of the adjustable guide plate on the guide mechanism, the sorted fertilizer particles can be effectively guided out and collected in batches, thereby improving the effective screening and collection of products and achieving effective scheduling of different products.

[0026] In summary, in the process of powder spraying treatment of fertilizer particles, the present application realizes the self-rotation of fertilizer particles, effectively improves the uniformity of the fertilizer particles during the powder spraying process, and also eliminates kinetic energy by means of the air pressure effect of the vacated fertilizer and the nozzle, thereby achieving the effect of sorting the fertilizer particles according to the different characteristics of the landing points of fertilizer particles of different masses and particle sizes. Combined with the setting of the material guiding mechanism, the batch collection and processing of different grades of the processed fertilizer particles is effectively realized.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Reference Figure 1-8 , a dissolving powder spraying device for fertilizer production, comprising:

[0038] A base 1, wherein a stepped groove is provided at the top of the base 1;

[0039] The powder spraying and sorting mechanism 3 is arranged at the top of the base 1 through a support frame. The powder spraying and sorting mechanism 3 includes an anastomotic ring 31. A flow guide mechanism 32 is arranged at the top of the anastomotic ring 31. A plurality of spiral guide tubes 322 are evenly arranged on the shell of the flow guide mechanism 32. The fertilizer particles are guided to give the fertilizer particles a tangential force for rotation, so as to ensure that the fertilizer can be rotated after being vacated. The powder spraying and sorting mechanism 3 also includes a nozzle 36 facing the spiral guide tube 322, which is used to spray the surface of the vacated fertilizer with a slow-release film raw material, and can also unload the vacated fertilizer particles under the action of the spraying air pressure, and realize the sorting operation of the fertilizer after the powder spraying according to the different landing points of the fertilizer caused by the final unloading.

[0040] The adjusting mechanism 4 is located in the stepped groove of the base 1. The adjusting mechanism 4 is provided with a forecast plate 48 which is matched with the matching ring 31, and the forecast plate 48 is rotatable, which is used to drive the fertilizer particles on the surface to rotate and provide centrifugal force to realize the waste entering the spiral guide tube 322, which is convenient for the subsequent emptying operation. The adjusting mechanism 4 also includes a receiving plate 49 located above the forecast plate 48, which is used to receive the fertilizer particles after the force is unloaded, so that the sorted fertilizer falls on the surface of the receiving plate 49 in an orderly layered manner;

[0041] The material guide mechanism 2 is installed on the upper part of one side of the base 1, and is used to export the sorted fertilizers in batches. The material guide mechanism 2 is provided with a material guide plate 24 and a material discharge port 25 for exporting the fertilizers. The material guide mechanism 2 includes a fixed plate Ⅰ21, and the top of the fixed plate Ⅰ21 is provided with two groups of slide grooves, and a pneumatic push rod Ⅰ23 is installed in the slide groove. The fixed plate Ⅰ21 is also slidably provided with a U-shaped slide 22 in the slide groove, and the output shaft of the pneumatic push rod Ⅰ23 is respectively connected to the two groups of arms of the U-shaped slide 22, thereby driving the U-shaped slide 22 to move.

[0042] An electric push rod 26 is installed at the top of the U-shaped slide 22. The output shaft of the electric push rod 26 vertically penetrates the U-shaped slide 22 downward and is connected to a guide plate 24. The side of the guide plate 24 close to the powder spraying and sorting mechanism 3 is in an arc shape. Under the action of the moving U-shaped slide 22, the guide plate 24 is moved above the receiving plate 49. The setting of the electric push rod 26 can prevent the guide plate 24 from directly contacting the fertilizer on the surface of the receiving plate 49 during the movement, and then continue to probe and fall to the boundary line of sorting. The electric push rod 26 is started to make the guide plate 24 fall and contact with the fertilizer particles. The receiving plate 49 is rotated, so that the sorted fertilizer is guided out under the action of the guide plate 24, and finally delivered to the discharge port 25 along the guide plate 24 to realize the collection of the fertilizer. This reciprocating process can realize the batch collection and processing of fertilizer particles of different particle sizes.

[0043] The feeding assembly 5 is used for adding fertilizer raw materials, and includes an adjustable guide block 53, which is convenient for delivering fertilizer particles to different positions on the preparation plate 48; the feeding assembly 5 includes a fixed plate Ⅱ51 fixedly installed on the side of the base 1, and a slide is provided on the top of the fixed plate Ⅱ51, and a guide block 53 is slidably arranged on the slide, and an inclined material discharge chute is provided on the guide block 53, and a pneumatic push rod Ⅱ52 for pushing the guide block 53 is provided on one side of the top of the fixed plate Ⅱ51, so that in actual use, the position of the guide block 53 extending into the preparation plate 48 can be effectively adjusted to ensure that the fertilizer raw materials can fall evenly on the surface of the preparation plate 48.

[0044] Reference Figure 8The adjusting mechanism 4 includes a push rod motor 41 located at the bottom end of the stepped groove on the base 1, and the top end of the output shaft of the push rod motor 41 is coaxially connected with a lifting column 42, and a support plate 43 is fixedly installed at the middle part of the outer side of the lifting column 42 to provide stable support, and a receiving plate 49 is rotatably provided at the top end of the lifting column 42 to receive the fertilizer after unloading;

[0045] A feed plate 48 is sleeved on the middle part of the outer side of the lifting column 42, and a gear ring 47 is provided at the bottom end of the feed plate 48 at the perforation. A motor 44 is installed on the top of the support plate 43, and a driving gear 46 meshing with the gear ring 47 is coaxially installed on the output shaft of the motor 44, thereby effectively realizing the rotation of the feed plate 48 and providing centrifugal force for the subsequent rotation of the fertilizer and the subsequent evacuation of the fertilizer.

[0046] The sizes of the expected plate 48 and the receiving plate 49 are consistent and are the same as the inner diameter of the anastomotic ring 31, so as to facilitate the blocking effect on the anastomotic ring 31 and prevent the fertilizer particles from being scattered.

[0047] Several groups of stabilizing rods 45 are fixedly installed on the top of the support plate 43. The top of the stabilizing rods 45 are fixedly installed with steel balls in contact with the bottom of the prediction plate 48, which are used to stably support the prediction plate 48 and reduce the friction during the rotation of the prediction plate 48 to ensure stable rotation.

[0048] Reference Figure 3-Figure 5 The flow guide mechanism 32 includes a cover shell 321, the top and bottom of the cover shell 321 are both opened, and a plurality of groups of inlet ports 323 are evenly opened on the lower side of the inner wall of the cover shell 321 for the fertilizer particles that follow the rotation of the prediction plate 48 to generate centrifugal force to drill in, and the shell of the cover shell 321 is evenly provided with spiral conduits 322 that are connected to the inlet ports 323 along its curvature, and the spiral conduits 322 are provided with a spiral curvature, so that the fertilizer particles that are drilled into the inlet ports 323 by the centrifugal force and move along the spiral conduits 322 finally have a certain spiral effect, so that the fertilizer particles can finally rotate after being vacated at the top opening of the spiral conduit 322.

[0049] The powder spraying and sorting mechanism 3 also includes a top plate 33 installed at the top of the guide mechanism 32 through a support rod. A storage hopper 35 is provided at the top of the top plate 33 for storing the slow-release film raw material. A pump body 34 connected to the storage hopper 35 is also installed at the top of the top plate 33. A conduit is connected to one end of the pump body 34, and a nozzle 36 flush with the top opening of the spiral conduit 322 is installed at the center of the bottom end of the top plate 33. The conduit is connected to the nozzle 36, so that the slow-release film raw material is effectively sprayed out and wrapped on the rotating and vacated fertilizer particles, and in this process, it is affected by the air pressure sprayed by the nozzle 36. The kinetic energy of the fertilizer particles is gradually unloaded, so that the fertilizer particles are wrapped with the slow-release membrane and then fall onto the receiving plate 49. Due to the different weights of the fertilizer particles, the time for unloading the kinetic energy is inconsistent, which leads to different final landing points of the fertilizer particles. The larger the particles and the larger the mass of the particles, the more time they consume, and the closer the landing point on the receiving plate 49 is to the center of the circle. Conversely, the smaller the particles and the smaller the mass, the less time they consume, and the landing point is located near the edge of the receiving plate 49, thereby effectively realizing the slow-release membrane coating operation of the fertilizer particles and the effective sorting process.

[0050] Working process: First, the push rod motor 41 in the adjusting mechanism 4 is started to make the upper component fall down, so that the pre-feed plate 48 is flush with the top surface of the base 1, and then the pneumatic push rod II 52 is started to send the fertilizer particles to the surface of the pre-feed plate 48 through the slideway on the surface of the guide block 53;

[0051] Then, the push rod motor 41 is started again to make the feed plate 48 and the matching ring 31 fit together, and then the motor 44 is started to realize that the driving gear 46 drives the gear ring 47 to rotate, so that the feed plate 48 follows the rotation, and under the continuous rotation, the surface fertilizer is driven to rotate, so that the fertilizer generates centrifugal force and moves to the surroundings, and finally the waste material drills into the inlet 323 on the inner wall of the guide mechanism 32, and under the action of the larger centrifugal force, after drilling into the inlet 323, it moves upward along the spiral guide tube 322. During the movement, under the action of the spiral setting of the spiral guide tube 322, the fertilizer particles finally show a certain rotation effect when they are vacated from the top opening of the spiral guide tube 322, and cooperate with the setting of the nozzle 36 above, so that the film release original The material is sprayed out and wrapped on the rotating fertilizer particles in the air, so that the surface of the fertilizer particles is effectively sprayed with powder and wrapped. In this process, the kinetic energy of the fertilizer particles is gradually unloaded under the action of the air pressure sprayed by the nozzle 36, so that the fertilizer particles are wrapped with the slow-release film and then fall onto the receiving plate 49. Due to the different weights of the fertilizer particles, the time of kinetic energy unloading is inconsistent, which leads to different final landing points of the fertilizer particles. The larger the particle and the larger the mass of the particle, the more time it consumes, and the closer the landing point on the receiving plate 49 is to the center of the circle. On the contrary, the smaller the particle and the smaller the mass, the less time it consumes, and the landing point is located near the edge of the receiving plate 49, which not only effectively realizes the slow-release film coating operation of the fertilizer particles, but also effectively realizes the sorting process.

[0052] After the wrapping process is completed, the push rod motor 41 is started to make the receiving plate 49 fall to a position flush with the top surface of the base 1, and then the electric push rod 26 is started to lift the guide plate 24, and then the pneumatic push rod I23 is started to make the U-shaped slide 22 drive the guide plate 24 to move, and finally the guide plate 24 moves to the boundary line of the sorted particles, and the receiving plate 49 is rotated to guide the sorted particles in batches one circle at a time, and then send them to the discharge port 25 for collection and processing, thereby realizing the final batch collection and processing of the fertilizer particles after the wrapping process.
