Description

Technical Field

[0001] The utility model relates to the technical field of microbial fertilizer processing, in particular to an agricultural microbial fertilizer dryer. Background Art

[0002] Microbial fertilizers, also known as biological fertilizers, inoculants or bacterial fertilizers, refer to a type of fertilizer product that uses the life activities of microorganisms as the core to enable crops to obtain specific fertilizer effects. There is an essential difference between microbial fertilizers and micro-fertilizers. The former is a living being, while the latter is a mineral element. Microbial resources are abundant, with a wide variety of types and functions. They can be developed into fertilizers with different functions and uses. In addition, microbial strains can be artificially selected and continuously purified and rejuvenated to improve their vitality.

[0003] At present, during the use of microbial fertilizer dryers, the fertilizer inside usually clumps or blocks due to moisture. Violent breaking by stirring may damage the microorganisms in the fertilizer, thereby affecting the activity of the microorganisms. In addition, wet fertilizer has a certain viscosity, which can easily cause it to adhere to the inner wall of the drying barrel during the drying process, making it difficult to remove it later. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An agricultural microbial fertilizer dryer, comprising:

[0006] A bottom plate and two support frames, the two support frames are fixedly mounted on the bottom plate, a drying barrel is rotatably mounted between the two support frames, a feed box is slidably connected to the bottom plate via a slide rod, a dual-axis motor is fixedly mounted on the bottom plate, and a driving structure for driving the drying barrel to rotate is mounted on the bottom plate;

[0007] A screening structure is installed on the feed box, and the screening structure includes a screening barrel fixedly connected to the side wall of the feed box, and the screening barrel is located in the drying barrel, the bottom plate is rotatably connected to two rotating shafts, and the two rotating shafts are transmission-connected to one of the output ends of the dual-shaft motor through a pulley assembly, the side wall of the bottom plate is rotatably connected to two rotating shafts, the two rotating shafts and the outer sides of the two rotating shafts are fixedly sleeved with bevel gears, and the adjacent bevel gears are meshed with each other, the outer sides of the two rotating shafts are fixedly sleeved with half gears, the side wall of the slide rod is fixedly connected to two spur racks, and the adjacent half gears are meshed with the spur racks.

[0008] Preferably, a vibration structure is installed on the support frame, and the vibration structure includes a support plate fixedly connected between two support frames, a striking plate is slidably connected to the side wall of the support plate, a spring is fixedly connected between the striking plate and the support plate, and a plurality of protrusions are fixedly connected to the side wall of the drying barrel.

[0009] Preferably, the driving structure includes spur gears fixedly connected to the outer sides of the two output ends of the biaxial motor, and two toothed rings are fixedly sleeved on the outer side of the drying barrel, and the spur gears are meshed with the toothed rings.

[0010] Preferably, a plurality of fixing plates are fixedly connected to the inner side of the drying barrel.

[0011] Preferably, a lid is rotatably installed on the side wall of the drying barrel, and a knob is rotatably connected to the side wall of the lid.

[0012] Preferably, a connecting plate is fixedly connected to the side wall of the feed box.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the present utility model, the biaxial motor drives the screening barrel to shake rapidly through the screening structure, so that the fertilizers directly entering the screening barrel from the feed box can collide with each other for crushing. The crushed fertilizers in small particles fall into the drying barrel through the screening holes on the lower side of the screening barrel for drying, and then the rotation of the drying barrel makes the fertilizers fall back into the screening barrel again, avoiding the situation of violent crushing by the stirring blades, and the repeated screening and heating make the drying effect better, preventing the occurrence of uneven heating;

[0015] In the present utility model, the rotation of the drying barrel makes the convex block push up the striking plate. After the convex block rotates, the striking plate impacts the upper side of the drying barrel through the action of two springs, thereby generating vibration. The vibration will make the fertilizers adhering to the inner wall of the drying barrel fall into the screening barrel, avoiding the loss of activity of the fertilizers caused by long-term heating, and also avoiding the subsequent difficult cleaning situation.

Detailed implementation manner

[0021] Refer to Figures 1-4 , an agricultural microbial fertilizer dryer, comprising:

[0022] A bottom plate and two support frames 1, the two support frames 1 are fixedly installed on the bottom plate, a drying barrel 2 is rotatably installed between the two support frames 1, the drying barrel 2 contains heating elements, which can generate heat to heat and dry the fertilizer inside. The drying barrel 2 is a prior art and will not be described in detail. A barrel cover 19 is rotatably installed on the side wall of the drying barrel 2, and a knob is rotatably connected to the side wall of the barrel cover 19. The barrel cover 19 is fixed by the knob. Opening the barrel cover 19 can take out the dried fertilizer. A feed box 3 is slidably connected to the bottom plate through a slide bar. A connecting plate 20 is fixedly connected to the side wall of the feed box 3. The connecting plate 20 can increase the supporting force at the bottom of the feed box 3. The feed box 3 is in contact with but not connected to the drying barrel 2. A double-shaft motor 4 is fixedly installed on the upper side of the support frame 1. A driving structure for driving the drying barrel 2 to rotate is installed on the support frame 1. The driving structure includes spur gears 16 fixedly connected to the outer sides of the two output ends of the double-shaft motor 4. Two toothed rings 17 are fixedly sleeved on the outer side of the drying barrel 2. The spur gears 16 are meshed with the toothed rings 17 to drive the rotation of the drying barrel 2 through the spur gears 16 and the toothed rings 17;

[0023] A screening structure is installed on the feed box 3, and the screening structure includes a screening barrel 5 fixedly connected to the side wall of the feed box 3. The fertilizer entering from the feed box 3 can directly enter the screening barrel 5, and the screening barrel 5 is located in the drying barrel 2. The screening barrel 5 is not directly connected to the drying barrel 2. A recess is opened on the upper side of the screening barrel 5, and a plurality of screening holes are opened on the lower side, so that the fertilizer can be turned into fine particles and fall from the screening holes. A plurality of fixed plates 18 are fixedly connected to the inner side of the drying barrel 2, and the fixed plates 18 are tightly fitted with the screening barrel 5. When the drying barrel 2 rotates, the fertilizer can be driven to rotate through the fixed plates 18. When the fertilizer moves to the upper side of the screening barrel 5, it falls back into the screening barrel 5 by gravity, thereby performing cyclic heating and drying, so that the drying effect is better. The bottom plate is rotatably connected to two rotating shafts 6, and the two rotating shafts 6 are connected to one of the output ends of the dual-axis motor 4 through a pulley assembly 7 for transmission. The pulley assembly 7 is dynamically connected, and is composed of two rotating wheels and a belt. The side wall of the bottom plate is rotatably connected to two rotating shafts 8. The two rotating shafts 6 and the outer sides of the two rotating shafts 8 are fixedly sleeved with bevel gears 9, and the adjacent bevel gears 9 are meshed with each other. The four bevel gears 9 are adjacent to each other, and the outer sides of the two rotating shafts 8 are fixedly sleeved with half gears 10. The side wall of the slide rod is fixedly connected to two spur racks 11, and the adjacent half gears 10 are meshed with the spur racks 11. When the half gears 10 on one side are meshed with the spur racks 11, the half gears 10 on the other side are not meshed with the spur racks 11, thereby driving the feed box 3 to slide back and forth. During the sliding process, the screening barrel 5 can screen the fertilizer inside, so that the fertilizer falls into the drying barrel 2 as fine particles for drying, and then is transported back to the screening barrel 5 by the fixed plate 18 for re-screening. The drying effect is better after multiple cycles.

[0024] A vibration structure is installed on the support frame 1, and the vibration structure includes a support plate 12 fixedly connected between the two support frames 1, a striking plate 13 is slidably connected to the side wall of the support plate 12, two springs 14 are fixedly connected between the striking plate 13 and the support plate 12, and a plurality of protrusions 15 are fixedly connected to the side wall of the drying barrel 2, and inclined sliding surfaces are provided on both sides of the protrusion 15. The striking plate 13 slides upward by the squeezing of the inclined sliding surfaces. When the protrusion 15 no longer squeezes the striking plate 13, the striking plate 13 strikes downward by the elastic force of the two springs 14, thereby striking and vibrating the surface of the drying barrel 2.

[0025] In the present utility model, first, the staff pours the microbial fertilizer to be dried from the feed box 3. At this time, the double-shaft motor 4 is turned on. The double-shaft motor 4 drives the drying barrel 2 to rotate through two spur gears 16 and a toothed ring 17. At the same time, the double-shaft motor 4 also drives two rotating shafts 6 to rotate respectively through two pulley assemblies 7. The rotating shafts 6 drive the rotating shaft 8 to rotate through two bevel gears 9. Because the rotating directions of the pulley assemblies 7 are the same, the rotating directions of the rotating shafts 8 are also the same. The rotation of the rotating shafts 8 drives the half gears 10 to rotate. When one side of the half gear 10 meshes with the straight rack 11, the half gear 10 on the other side does not mesh with the straight rack 11. Therefore, the rotation of the two half gears 10 causes the feed box 3 to make a reciprocating motion. The motion of the feed box 3 causes the screening barrel 5 to make a reciprocating motion, so as to quickly screen the fertilizer inside, enabling the fertilizer to fall through the screening holes on the lower side of the screening barrel 5. At this time, the rotating drying barrel 2 drives the fertilizer to rotate through a plurality of fixed plates 18 fixedly connected to the inner side. When it rotates above the screening barrel 5, it falls back into the screening barrel 5 by gravity for screening. Repeating this process many times makes the drying effect better, prevents the fertilizer from agglomerating, and also prevents uneven heating. While the drying barrel 2 is rotating, the drying barrel 2 drives a plurality of bumps 15 to rotate. The striking plate 13 slides upward by the extrusion of the inclined sliding surface of the bump 15. When the bump 15 no longer presses the striking plate 13, the striking plate 13 strikes downward by the elastic force of two springs 14, thereby striking and vibrating the surface of the drying barrel 2. The vibration causes the fertilizer adhering to the inner wall of the drying barrel 2 to fall into the screening barrel 5, avoiding the inactivation of the fertilizer caused by long-term heating and also avoiding the subsequent difficult cleaning situation.
