Description

Technical Field

[0001] The invention relates to the technical field of fertilizer granulation devices, in particular to a solid fertilizer granulation device. Background Art

[0002] During the agricultural sowing process, fertilization is usually required to supply nutrients to crops and ensure effective and rapid growth of crops.

[0003] Most of these fertilizers are solid granular fertilizers. During the production process, a granulating device is required to granulate the fertilizer raw materials to facilitate subsequent practical use. However, in the actual granulation process, since the raw materials are mostly fine particles, they are not compact enough during the actual processing, resulting in uneven subsequent granulation. In addition, during the actual sowing process, due to insufficient compactness, they are easily dissolved quickly, which does not achieve the purpose of slow release and affects the actual purpose of long-term fertility supply. For this reason, we propose a solid fertilizer granulating device. Summary of the invention

The outer sides of the pulleys II and I are sleeved with the same set of synchronous belts, and a driving motor for driving the pulley I to rotate is arranged on the bottom side of the deflection plate, so that the synchronous rotation of the pulley II is realized under the action of the synchronous belt, and the pulley II is coaxially connected to the bottom surface of the receiving circular silo, thereby realizing the rotation of the receiving circular silo, driving the raw materials inside to roll, increasing the contact probability, and realizing the bonding of the fertilizer raw materials.

[0012] As a preferred technical solution of the present application, two groups of atomizing nozzles are installed on the granulating assembly, and a liquid guide tube for guiding water vapor is connected to the atomizing nozzle.

[0015] The extrusion molding assembly includes a swing motor installed on the outside of the support frame, the output shaft of the swing motor passes through the support frame and is connected to a cam, and a pressing and granulating component arranged on the inside of the support frame is connected below the cam, and the pressing and granulating component is used to press and form the fertilizer and fall it in linkage with the cam;

[0016] The support frame is located on the inner side of the receiving round silo, and telescopic rods are provided on both sides of the support arms, and the telescopic rods pass through the support arms and are connected to the pressing and granulating components.

[0020] A number of pushing vertebrae are evenly arranged in the gap between the ball receiving grooves II at the bottom end of the pressing upper die, and insertion holes corresponding to the pushing vertebrae are evenly arranged between the ball receiving grooves I on the pressing lower die. When the pressing upper die and the pressing lower die are completely pressed and stabilized, the pushing vertebrae are completely inserted into the corresponding insertion holes. At this time, the fertilizer raw materials originally retained above the pressing lower die but not inside the ball receiving groove I will be pushed to between the ball receiving grooves I and II under the gradual pressing action of the pushing vertebrae, thereby further improving the density of the pressed fertilizer particles and thus improving the compactness of the finished product.

[0021] As a preferred technical solution of the present application, a resistance spring is sleeved on the outer side of the flip shaft, and the resistance spring is in resistance with the outer side of the support frame, so as to ensure the stability of the pressed lower mold when it is not driven by external force, avoid self-rotation, and ensure the effective collection of the fertilizer after it falls;

[0022] A meshing gear is also installed on the flip shaft, and linkage racks meshing with the meshing gear are fixedly installed on both sides of the pressing upper die, so as to ensure that the meshing gear and the pressing lower die can be driven to flip during the pressing and rising process of the pressing upper die. The length of the gear teeth on the linkage rack is consistent with the length of the gear teeth of the meshing gear, and the overall length of the linkage rack is much larger than the length of the surface gear teeth, and the initial state of the pressing lower die is a state facing the pressing upper die, so as to effectively ensure that the pressing lower die can be driven to flip for one circle during the pressing process of the pressing upper die, and after driving the pressing lower die to flip for one circle during the molding and pressing process, its state is maintained to receive the fertilizer, so as to provide load-bearing guarantee for subsequent molding and extrusion. When the molding is completed, the pressing upper die returns to its position, and the linkage rack follows to rise, so as to realize the flipping of the pressing lower die for one circle again.

[0026] The beneficial effects of the present invention are:

[0027] 1. Water vapor is supplied through the atomizing nozzle to increase the humidity of the fertilizer raw materials, ensuring the effective forming and granulation of the subsequent fertilizer particles. The fertilizer falls along the slope and hits the surface of the fixed bar to perform a certain beating operation, which improves the compactness of the fertilizer and preliminarily guarantees the quality of the subsequent finished products.

[0028] 2. When the fertilizer falls into the pressing and granulating component, it is pressed and formed under the action of the linked pressing upper die and the pressing lower die, and the density is increased as much as possible under the action of the pushing cone, thereby improving the compactness of the actual fertilizer particles, thereby achieving the purpose of improving the quality of the finished product. In addition, it can be automatically poured out under the action of the subsequent linked pressing upper die and the pressing lower die, making room for subsequent forming;

[0029] 3. The sorting operation of the shaped fertilizer particles is realized under the action of the guide plate in the package processing mechanism, and the surface slow-release coating film is sprayed with the slow-release film raw material nozzle in cooperation with the slow-release film raw material nozzle, thereby achieving the purpose of improving the quality of the finished product.

The telescopic rods 324 penetrate the support arms and are connected to the pressing and granulating components 326. The outer side of the telescopic rods 324 is sleeved with springs 325, thereby ensuring that the components on the pressing and granulating components 326 can be returned to their original positions under the action of the springs 325 after following the action of the cam 323, so as to facilitate the continuous and effective molding of fertilizer particles.

[0053] Reference Figure 6 and Figure 7 The pressing granulation component 326 includes a pressing upper die 3261, and guide bars 3262 are fixedly installed on both sides of the pressing upper die 3261. The supporting arms on both sides of the support frame 321 located inside the receiving round bin 31 are provided with guide grooves corresponding to the guide bars 3262, so as to ensure that the pressing upper die 3261 can move stably after being acted upon by the cam 323;

[0054] The pressing and granulating component 326 also includes a pressing lower die 3264. A flip shaft 3265 penetrating the support frame 321 is fixedly installed in the middle of both sides of the pressing lower die 3264 to facilitate the rotation of the pressing lower die 3264 as a whole.

[0055] The bottom of the upper pressing die 3261 is provided with a plurality of ball receiving grooves II 32610, and the top of the lower pressing die 3264 is evenly provided with a plurality of ball receiving grooves I 3269 corresponding to the ball receiving grooves II 32610, so that the fertilizer is conveniently and effectively ensured to be round and smooth when the two are pressed together;

When the pressing upper mold 3261 and the pressing lower mold 3264 are completely pressed and stabilized, the pushing vertebrae 3268 are completely inserted into the corresponding insertion holes. At this time, the fertilizer raw materials originally retained above the pressing lower mold 3264 but not inside the ball receiving groove I 3269 will be pushed to between the ball receiving groove I 3269 and the ball receiving groove II 32610 under the gradual pressing action of the pushing vertebrae 3268, thereby further improving the density of the pressed fertilizer particles and thus improving the compactness of the finished product.

[0061] The processing component 42 includes a bin body 421. An opening is provided on one side of the top end of the bin body 421 facing the guide plate 43 for introducing fertilizer particles. A plurality of groups of inclined screens 423 are evenly provided inside the bin body 421 for convenient screening of the introduced fertilizer particles and classification of particles with the same particle size to further improve the quality.

[0062] Working process: First, the push rod motor 5 drives the pushing rod 6 to adjust the angles of the overall deflection adjustment mechanism 2 and the disc granulation mechanism 3, so that the fertilizer cannot rotate to the top during the rotation of the receiving round bin 31. After the fertilizer raw material is injected into the receiving round bin 31, water vapor is supplied through the atomizing nozzle 34, so that the humidity of the fertilizer raw material is increased during the rotation of the receiving round bin 31, thereby increasing the viscosity to a certain extent. Under the action of the continuously rotating receiving round bin 31, the fertilizer particles are continuously in contact, so that they are bonded and become larger. In this process, the fertilizer falls along the slope and hits the surface of the fixing bar 36, thereby performing a certain beating operation, thereby increasing the compactness of the fertilizer and preliminarily ensuring the quality of the subsequent finished product.

[0063] Then, after the compaction process reaches a certain degree, the angles of the deflection adjustment mechanism 2 and the disc granulation mechanism 3 are adjusted again, so that the fertilizer can follow the rotation to the top of the receiving silo 31, and in this process, the angles of the deflection adjustment mechanism 2 and the disc granulation mechanism 3 are periodically adjusted, so that the fertilizer rotated to the top of the receiving silo 31 falls quickly, and then falls to the inside of the granulation assembly 32, and is sent to the pressing granulation component 326 under the action of the guide block 327, so as to provide feeding assistance for the subsequent fertilizer pressing and molding;

[0064] When the fertilizer falls to the top of the pressing lower die 3264 in the pressing granulating component 326, the fertilizer is scattered in the ball receiving groove Ⅰ 3269 and the surface of the pressing lower die 3264, and then the swing motor 322 is started to rotate the cam 323 to drive the pressing upper die 3261 to press down. During the pressing process, the pushing cone 3268 at the bottom of the pressing upper die 3261 is continuously inserted into the corresponding insertion hole on the pressing lower die 3264, so that the fertilizer that is not on the inner side of the ball receiving groove Ⅰ 3269 is The raw materials are pushed into the spherical space of the ball receiving groove I 3269 and the ball receiving groove II 32610 to increase the density of the actually pressed fertilizer particles as much as possible. After the pressing is completed, the cam 323 continues to rotate, and the pressing upper die 3261 is reset under the action of the telescopic rod 324 and the spring 325, and drives the linkage rack 3263 to move, so that the pressing lower die 3264 rotates under the action of the meshing gear 3266, and drives the formed fertilizer particles to fall;

[0065] The formed fertilizer particles are finally sent to the processing part 42 along the guide plate 43, and are sorted under the action of the screen 423, and slide down along the screen 423. During the sliding process, they are sprayed with a slow-release coating film on the surface by the slow-release film raw material nozzle 422, thereby achieving the purpose of improving the quality of the finished product. At this point, the fertilizer granulation forming operation is completed.
