Abstract
Description
Technical Field
[0001] The invention relates to the technical field of slow-release fertilizer production, in particular to a slow-release fertilizer coating device. Background Art
[0002] In the prior art, a slow-release fertilizer is a kind of fertilizer that is formed by evenly spraying a binder onto the surface of the slow-release fertilizer particles through a binder nozzle in a coating device. This protective layer can control the nutrient release rate and time of the slow-release fertilizer, so that the nutrients in the waste are slowly released in the soil, thereby meeting the nutrient needs of crops at different growth stages, thereby maximizing the utilization of the slow-release fertilizer.
[0003] In the prior art, the slow-release fertilizer produces particles of the same size. When the slow-release fertilizer is added to the coating machine for coating, the sprayed binder is always in a uniform amount, and the heating temperature is always at the rated temperature. This will result in insufficient binder for larger particles, while smaller particles may include more binder, which will affect the later use effect of the slow-release fertilizer. Moreover, because the heating temperature is always at the rated temperature, the heating effect of the particles including the binder will be too high, and the outer surface of the particles including more binder will reach the required heating temperature. The internal binder may not be fully heated, which may cause some fertilizers to release nutrients quickly in a short time, while some fertilizers are released slowly, which cannot meet the long-term stability needs of crops. For this reason, we propose a slow-release fertilizer coating equipment. Summary of the invention

Moreover, because the heating temperature is at the rated temperature, the heating effect of the particles including the binder is too high, and the outer surface of the particles including more binder reaches the required heating temperature, and the internal binder may not be fully heated, which may cause some fertilizers to release nutrients quickly in a short time, while some fertilizers are released slowly, and the long-term stability needs of crops cannot be met.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0041] Embodiment 1
[0042] See also Figures 1 to 14 The present invention provides a technical solution: a slow-release fertilizer coating device, comprising:
[0043] A screening mechanism 2, which is arranged inside the coating box 1 and is used to screen slow-release fertilizers of different particle sizes;
[0044] A discharging mechanism 3 is provided on one side of the coating box 1, and is used for discharging particles from large to small in sequence;
[0045] The coating mechanism 4 is arranged inside the coating box 1, and the number of the coating mechanisms 4 is two, and is used to adjust the binder injection port according to particles of different sizes to perform coating work;
[0046] A heating mechanism 5, which is disposed inside the coating box 1 and is used to heat the slow-release fertilizer particles wrapped with a binder;
[0047] A weight sensing mechanism 6, which is disposed inside the coating box 1 and is used to sense slow-release fertilizers of different particle sizes;
[0048] A material guiding mechanism 9, which is arranged inside the coating box 1 and is used to guide and collect the coated slow-release fertilizer particles;
[0049] The transmission mechanism 7 is arranged on one side of the dressing box 1, and the transmission mechanism 7 is used to drive the power transmission of the weight sensing mechanism 6 to turn the material guiding mechanism 9 to a desired angle;
[0050] By providing the screening mechanism 2, the slow-release fertilizer particles can be screened into particles of different sizes, so that the required amount of adhesive and the required heating temperature can be sprayed according to the particles of different sizes during the subsequent wrapping and heating. By providing the discharging mechanism 3, the weight sensing mechanism 6, the material guiding mechanism 9 and the transmission mechanism 7, the slow-release fertilizer particles can be discharged in order from large to small. The gravitational acceleration of the larger particles when falling is greater than that of the smaller particles, and the weight sensing mechanism 6 can sense the weight of the particles of different sizes. In this way, particles of different sizes can be detected, and the discharging mechanism 3 can be driven by the transmission mechanism 7 to discharge in order from large to small, and at the same time, the material guiding mechanism 9 can be driven to adjust to the required discharging angle according to the size of the released fertilizer particles dropped. For the released fertilizer with larger particles, the smaller the angle between the discharging structure and the horizontal line, the discharge speed of the large-particle released fertilizer can be slowed down, thereby extending the heating time, and completing the heating effect of the binder wrapped in the large-particle released fertilizer. For the released fertilizer with smaller particles, the angle between the discharging structure and the horizontal line is increased, thereby improving the discharge of the small-particle released fertilizer. Speed, to prevent the heating time from being too long and affecting the use effect, thereby ensuring the normal use of the release fertilizer and meeting the long-term stable use needs of crops; by providing the coating mechanism 4 and the heating mechanism 5, the particle size of the release fertilizer can be detected according to the weight sensing mechanism 6, and the coating mechanism 4 can be controlled to spray the required binder according to the release fertilizer of particles of different sizes. For the large-particle release fertilizer, a large amount of binder is sprayed to ensure that the large-particle release fertilizer is more evenly wrapped, avoiding the phenomenon that the large-particle release fertilizer includes insufficient binder, and when discharging the small-particle slow-release fertilizer, the amount of binder can be reduced. The spraying of the sprayed adhesive can prevent the occurrence of excessive spraying of the adhesive, which causes the small-particle fertilizer to wrap a large amount of adhesive, resulting in a long nutrient release time, affecting the subsequent use, and at the same time, the heating temperature of the heating mechanism 5 is controlled according to the slow-release fertilizer particles of different sizes, thereby ensuring that the heating temperature is increased when discharging the large-particle slow-release fertilizer to ensure that the adhesive wrapped by the large-particle slow-release fertilizer is fully heated, and the temperature can be lowered when discharging the small-particle slow-release fertilizer, thereby preventing the heating temperature of the adhesive wrapped by the small-particle slow-release fertilizer particles from being too high, resulting in the adhesive being unable to provide the desired effect for the small-particle slow-release fertilizer;
[0051] When in use, the added slow-release fertilizer particles can be screened into particles of different sizes through the screening mechanism 2, and then the particles are discharged from large to small. When discharging the largest particles of slow-release fertilizer, the weight of the slow-release fertilizer particles can be detected by the weight sensing mechanism 6, so that after detecting the weight of the granular slow-release fertilizer, the weight sensing mechanism 6 drives the material guiding mechanism 9 to adjust to a small angle and heats the granular slow-release fertilizer, thereby slowing down the discharge speed of the granular slow-release fertilizer. After completing the discharge of large-particle slow-release fertilizer, the weight sensing mechanism 6 can drive the discharging mechanism 3 to move through the transmission mechanism 7, and then discharge the next specification of slow-release fertilizer particles. The transmission mechanism 7 can feedback information to the coating mechanism 4, and the coating mechanism 4 can be controlled to adjust the size of the binder injection head according to the particle size of the slow-release fertilizer, thereby adjusting the injection amount, and then the heating mechanism 5 is adjusted to the temperature required for heating according to the slow-release fertilizer of different particle sizes, and finally discharged and collected through the material guiding mechanism 9.

[0053] When in use, the slow-release fertilizer particles are poured into the coating box 1. When the coating box 1 is vibrated, the slow-release fertilizers of different particle sizes are screened through the multiple screening nets 26. After the first screening net 26 screens the slow-release fertilizer with the smallest particles, the discharge plate 32 can block the discharge port of the fixed baffle 27, and the first motor 22 is controlled to rotate the first reciprocating screw rod 23, so that the first reciprocating screw rod 23 drives the slope thread block 25 to slide on the outside of the first limit rod 24, and the slope thread block 25 can push the first slope baffle 290 to move downward, so that the slope baffle The plate 290 slides downward in the first slide groove 28 to compress the first spring 29, and the remaining slow-release fertilizer particles can be discharged through the discharge port in the slope baffle 290, and then the slow-release fertilizer particles of the second size are screened through the second screening net 26. Thereafter, the slope threaded block 25 is moved to push the second slope baffle 290 to move and discharge the remaining particles of the slow-release fertilizer particles. The last screening net 26 is used to screen the slow-release fertilizer with the largest particles. The slope baffle 290 is pushed to move by the slope threaded block 25. At this time, the slow-release fertilizer with the largest particles is directly discharged for processing.

[0057] When in use, according to the touch switch 77 that the transmission mechanism 7 is driven to touch, the size of the discharged slow-release fertilizer particles is fed back, and then the second motor 42 is controlled to operate and rotate the second reciprocating screw 43, so that the second reciprocating screw 43 drives the threaded plate 44 to slide on the outside of the third limit rod 45. When the threaded plate 44 is driven away from the slope fixing block 41, the first sliding block 491 drives the first rotating rod 490, and the first rotating rod 490 stretches the nozzle 49 to expand the opening, thereby increasing the discharge amount of the adhesive, so that the first A rotating rod 490 drives the first slider 491 to slide in the threaded plate 44, and the nozzle 49 of the nozzle is made of elastic material.

[0060] The weight sensing mechanism 6 includes a fixed limit plate 61 fixedly connected to the inside of the dressing box 1, a sensing plate 62 slidably connected to the inside of the fixed limit plate 61, a gravity sensor 63 fixedly connected to the inner side of the fixed limit plate 61 and located below the sensing plate 62, a limit connection block 64 fixedly connected to one side of the fixed limit plate 61, an empty slot block 65 fixedly connected to one side of the dressing box 1 and located outside the limit connection block 64, and a second slider fixedly connected to the bottom of the limit connection block 64 and located inside the empty slot block 65 66, the second slider 66 is slidably connected to the empty slot block 65, the bottom of the second slider 66 is fixedly connected to a third spring 69, the interior of the second slider 66 is fixedly connected to a magnet 67, the interior of the empty slot block 65 is equidistantly fixedly connected to a plurality of electromagnets 68, one side of the second slider 66 is fixedly connected to an L-shaped driving block 690, one side of the clothing box 1 is fixedly connected to two fourth limiting rods 692, and the outer sides of the two fourth limiting rods 692 and located on the outer side of the L-shaped driving block 690 are slidably connected to a track plate 691;
[0061] When in use, when the induction plate 62 is pressed by the slow-release fertilizer particles, the gravity detection is performed through the gravity sensor 63, and at the same time, the limit connecting block 64 is driven to move downward through the fixed limit plate 61, so that the limit connecting block 64 drives the second slider 66 to slide downward in the empty slot block 65 to compress the third spring 69, and then the magnet 67 in the second slider 66 can be moved to the position of the lowest electromagnet 68. At this time, the lowest electromagnet 68 is in an energized state, and the upper multiple electromagnets 68 are in an off-state. The lowest energized electromagnet 68 attracts the magnet 67 to fix the position of the second slider 66. At this time, all the electromagnets 68 above the lowest electromagnet 68 are turned on, and when the second slider 66 moves downward, it will drive the L-shaped driving block 690 to move downward. The L-shaped driving block 690 moves downward in the track plate 691. When the L-shaped driving block 690 moves to the lowest position of the track plate 691, the track plate 691 is driven by external force to make the inner wall of the slope track close to the L-shaped driving block 690. When the induction plate 62 above the gravity sensor 63 no longer senses the fall of the largest slow-release fertilizer particles, the electromagnet 68 at the lowest end is powered off. The second electromagnet 68 attracts the magnet 67 in the second slider 66 and pushes the track plate 691 away from the coating box 1 through the L-shaped driving block 690, so that the track plate 691 slides on the outside of the fourth limit rod 692. The above movement is repeated, so that the falling particles become smaller and smaller, which drives the inclination angle of the material guiding mechanism 9 to become larger and larger. After the processing is completed, the L-shaped driving block 690 can be reset.
[0062] The material guiding mechanism 9 includes a second rotating rod 91 rotatably connected to the inside of the clothing box 1, a material collecting guide plate 92 is fixedly connected to the outside of the second rotating rod 91, a heating plate 93 is fixedly connected to the inside of the material collecting guide plate 92, a rotating block 95 is rotatably connected between the track plate 691 and the material collecting guide plate 92, and a guide plate 94 is fixedly connected to the inside of the clothing box 1 and above the material collecting guide plate 92;
[0063] When in use, when the largest particles of slow-release fertilizer fall, the slow-release fertilizer particles can be guided by the guide plate 94, and supplementary heating can be performed by the heating plate 93, and the heating plate 93 is adjusted to the required temperature. At the same time, the slow-release fertilizer particles that fall are getting smaller and smaller, so that the track plate 691 drives the collection guide plate 92 through the rotating block 95, and the collection guide plate 92 drives the second rotating rod 91 to flip in the coating box 1, and then the inclination angle of the collection guide plate 92 can be reduced in sequence according to the slow-release fertilizer particles, while the inclination angle becomes larger and larger, so that the large particles of slow-release fertilizer can get sufficient heating time, and the small particles of slow-release fertilizer can be quickly discharged and collected to prevent the heating from being too long, and finally discharged and collected through the collection guide plate 92.
[0064] Embodiment 2
[0065] like Figure 1-14 In the second embodiment, other structures remain unchanged, and the difference from the first embodiment is
[0066] The transmission mechanism 7 includes a rotating shaft 71 fixedly connected to one end of the second rotating rod 91, one end of the rotating shaft 71 is fixedly connected to a first pulley 72, a torsion spring 73 is sleeved on the outer side of the rotating shaft 71, and one end of the torsion spring 73 is fixedly connected to the clothing box 1, and the end of the torsion spring 73 away from the clothing box 1 is fixedly connected to the first pulley 72, the outer side of the first pulley 72 is fixedly connected to a touch block, a plurality of second fixed blocks 76 are fixedly connected to one side of the clothing box 1 at equal intervals, a touch switch 77 is fixedly connected to one side of the second fixed block 76, a winding wheel 75 is rotatably connected to one side of the clothing box 1, a second pulley 74 is fixedly connected to one side of the winding wheel 75, a belt is provided between the second pulley 74 and the first pulley 72, and a rope is fixedly connected between the winding wheel 75 and the connecting plate 38;
[0067] When in use, when the L-shaped driving block 690 moves to the bottom end of the track plate 691, the torsion spring 73 can drive the rotating shaft 71 through the first pulley 72, and the rotating shaft 71 drives the material guide mechanism 9 to drive the track plate 691 to move to the inner wall of the slope track of the L-shaped driving block 690. When the second rotating rod 91 is rotated clockwise, the rotating shaft 71 can drive the first pulley 72 to rotate, so that when the first pulley 72 flips, it will drive the touch block to touch the first touch switch 77. The switch 77 can feedback the information of the particle size to the coating mechanism 4 and the heating mechanism 5. The first touch switch 77 feedbacks the information of the slow-release fertilizer of the largest particle, and the last touch switch 77 feedbacks the information of the slow-release fertilizer of the smallest particle. In this way, when the first pulley 72 is driven, the second pulley 74 can be driven to rotate through the belt, and the second pulley 74 drives the winding wheel 75 to move the winding connecting plate 38, and the length of the fixed-distance winding rope of the winding wheel 75 is equal to the distance from the discharge plate 32 to the next fixed baffle 27.

[0070] When in use, the vibration motor 81 is controlled to run and vibrate, driving the clothing box 1 to vibrate up and down, so that the clothing box 1 drives the sliding plate 84 at the bottom of the four support columns 82 to slide in the empty slot foot block 83, and then the fourth spring 85 can be compressed by the sliding plate 84, and the vibration screening work of the clothing box 1 can be realized through the cooperation of the vibration motor 81 and the fourth spring 85;
[0071] The inner diameter of the mesh opening of the screening net 26 increases from left to right. When in use, the slow-release fertilizer of small particles to large particles can be screened out from left to right.
