Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer granulation equipment, specifically a soil and fertilizer compound granulation device. Background Technology

[0002] Soil improvement and efficient fertilization are core issues in modern agriculture and ecological restoration. In traditional fertilization methods, fertilizers are typically applied directly to the soil surface, making them susceptible to nutrient loss due to rain erosion or volatilization. Studies show that nitrogen fertilizer utilization rates are generally below 30%, and phosphorus fertilizer utilization rates are less than 20% in the current season. This not only wastes resources but can also lead to non-point source pollution problems such as water eutrophication and soil acidification. Furthermore, long-term use of a single type of fertilizer can damage soil aggregate structure, reduce soil water and fertilizer retention capacity, and further exacerbate the challenges to agricultural sustainability.

[0003] In recent years, the technology of granulating fertilizers after mixing them with soil (or organic substrates) has gradually attracted attention. These granules can reduce nutrient loss and improve fertilizer utilization through physical coating and slow release, while also improving soil porosity and microbial activity. However, existing granulation equipment still faces many challenges in mixing soil and fertilizers, such as uneven material mixing and low granule strength. There is an urgent need to develop more efficient compound granulation devices to meet the dual demands of modern agriculture for precision fertilization and soil improvement. Utility Model Content

[0004] The purpose of this invention is to provide a soil and fertilizer compound granulation molding device to solve the problems of uneven material mixing and low granulation strength in the existing compound granulation molding devices mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soil and fertilizer compound granulation molding device, including a workbench, a mixing and crushing mechanism, a conveying mechanism and a shearing and guiding mechanism are respectively arranged above the workbench, and an electromagnetic valve is provided at the connection between the mixing and crushing mechanism and the conveying mechanism. The mixing and crushing mechanism includes a mixing and crushing box and a mixing and crushing motor installed on the top of the mixing and crushing box. The mixing and crushing motor is fixedly connected to a rotating shaft via a coupling. The other end of the rotating shaft passes through the top of the mixing and crushing box and extends to near the bottom of the inner cavity of the mixing and crushing box. Crushing blades and stirring blades are fixedly connected to the outer wall of the inner cavity of the mixing and crushing box. The crushing blades and stirring blades are arranged alternately on the outer wall of the rotating shaft.

[0006] The present invention is further configured such that: the conveying mechanism includes a conveying box fixedly connected to the top of the workbench by a support block and a conveying motor disposed on the left side of the conveying box; the output end of the conveying motor is fixedly connected to a round shaft by a coupling; the other end of the round shaft passes through the outer wall of the left side of the conveying box and extends to the right side near the inner cavity of the conveying box; and a conical output port is disposed on the right side of the conveying box; and spiral blades are fixedly connected to the inner and outer walls of the conveying box by the round shaft.

[0007] Using the above technical solution, after the soil and fertilizer are crushed and mixed, they enter the conveyor box. The conveyor motor is started, and the conveyor motor drives the circular shaft to rotate. The circular shaft drives the spiral blade to rotate, thereby conveying the material on the left side of the conveyor box to the right side. Under the action of the conical output port on the right side of the conveyor box, the soil and fertilizer mixture is granulated into cylindrical particles, which are quite compact, not easy to loosen, and easy to transport.

[0008] The present invention is further configured such that: the shearing guide mechanism includes a long shaft rotatably connected to the top of the workbench via a support plate and a pulley that is connected to the long shaft and the round shaft for transmission; a cutting blade is fixedly connected to the outer wall of the other end of the long shaft; the cutting blade is flush with the end of the conical output port designed on the conveyor box; and a guide ring is provided on the outside of the conical output port of the conveyor box.

[0009] Using the above technical solution, while the circular shaft rotates, the long shaft rotates through the transmission of the pulley. The long shaft drives the cutting blades symmetrically arranged on the outer wall of the long shaft to rotate, so that the cutting blades periodically cut the material output from the end of the conical output port on the conveyor box. Under the action of its own gravity, the material falls down through the arc-shaped guide ring, preventing it from falling from a height and causing granulation failure. At the same time, it also reduces the amount of manual handling.

[0010] The present invention is further configured such that: the bottom of the mixing and crushing box is connected to the top left side of the conveying box near the conveying motor, and the solenoid valve is fixedly installed at the connection between the mixing and crushing box and the conveying box.

[0011] Using the above technical solution, the connection and closure of the mixing and crushing box and the conveying box are achieved by controlling the solenoid valve.

[0012] The present invention is further configured such that: the top of the mixing and crushing box is provided with a feed inlet, and the mixing and crushing box is provided with a box cover at the feed inlet.

[0013] By adopting the above technical solution, the feed inlet is set to facilitate the pouring of fertilizer and soil into the mixing and crushing box, and the box cover is set to prevent the material from being thrown out of the feed inlet when the mixing and crushing box is working.

[0014] The present invention is further configured such that: the mixing and crushing motor and the conveying motor are respectively fixedly installed on the top of the mixing and crushing box and the outer left side wall of the conveying box through the frame, and both the mixing and crushing motor and the conveying motor are geared motors.

[0015] By adopting the above technical solution, the entire device is powered by a mixing and crushing motor and a conveying motor, and the granulation speed of soil and fertilizer is controlled by controlling the rotation speed of the mixing and crushing motor and the conveying motor.

[0016] The present invention is further configured such that: the guide ring is symmetrically provided with guide openings near the worktable, and the guide ring is fixedly installed on the worktable by a support frame.

[0017] By adopting the above technical solution, the guide ring can guide the granulated soil and fertilizer materials to the workbench after cutting, and at the same time cover the cutting blade to prevent workers from accidentally touching the exposed blade and causing injury.

[0018] This invention provides a soil and fertilizer compound granulation and forming device. It has the following beneficial effects: (1) This utility model uses a mixing and crushing motor to drive the rotating shaft to rotate, and the rotating shaft drives the crushing blades and stirring blades to rotate. The rotating crushing blades crush the soil and fertilizer poured into the mixing and crushing box, avoiding uneven mixing of lumpy soil or fertilizer. The rotation of the stirring blades mixes the soil and fertilizer in the box evenly, achieving the requirements of granulation.

[0019] (2) This utility model uses a conveyor motor to drive a round shaft to rotate, and the round shaft drives the spiral blades to rotate, thereby conveying the material on the left side of the conveyor box to the right side. Under the action of the conical output port on the right side of the conveyor box, the soil and fertilizer mixture is granulated into a cylindrical shape, which is quite compact, not easy to loosen, and easy to transport.

[0020] (3) This utility model uses a pulley to drive the round shaft to rotate the long shaft, and the long shaft to rotate the cutting blade. This allows the cutting blade to periodically cut the material output from the end of the conical output port on the conveyor box. Under its own gravity, the material falls down through the arc-shaped guide ring, preventing it from falling from a height and causing granulation failure. It also reduces the amount of manual handling and covers the cutting blade to prevent it from being exposed and causing accidental injury to workers. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution: a soil and fertilizer compound granulation molding device, including a workbench 1, a mixing and crushing mechanism 2, a conveying mechanism 3 and a shearing and guiding mechanism 4 respectively arranged on the upper part of the workbench 1, and an electromagnetic valve 5 is provided at the connection between the mixing and crushing mechanism 2 and the conveying mechanism 3. The mixing and crushing mechanism 2 includes a mixing and crushing box 21 and a mixing and crushing motor 22 installed on the top of the mixing and crushing box 21. The top of the mixing and crushing box 21 has a feed inlet, and the mixing and crushing box 21 is equipped with a box cover at the feed inlet. The feed inlet facilitates the pouring of fertilizer and soil into the mixing and crushing box 21, and the box cover prevents the material from being thrown out of the feed inlet when the mixing and crushing box 21 is working. The mixing and crushing motor 22 is fixedly connected to a rotating shaft 23 through a coupling. The other end of the rotating shaft 23 passes through the top of the mixing and crushing box 21 and extends to the bottom of the inner cavity of the mixing and crushing box 21. Crushing blades 24 and stirring blades 25 are fixedly connected to the outer wall of the inner cavity of the mixing and crushing box 21, and the crushing blades 24 and stirring blades 25 are arranged alternately on the outer wall of the rotating shaft 23. The conveying mechanism 3 includes a conveying box 31 fixedly connected to the top of the workbench 1 via a support block, and a conveying motor 32 disposed on the left side of the conveying box 31. The bottom of the mixing and crushing box 21 is connected to the top left side of the conveying box 31 near the top of the conveying motor 32. A solenoid valve 5 is fixedly installed at the connection between the mixing and crushing box 21 and the conveying box 31. The connection and closure of the mixing and crushing box 21 and the conveying box 31 are achieved by controlling the solenoid valve 5. A round shaft 33 is fixedly connected to the output end of the conveying motor 32 via a coupling. The other end of the round shaft 33 passes through the outer left wall of the conveying box 31 and extends to the side near the conveying box 31. On the right side of the inner cavity and on the right side of the conveyor box 31, there is a conical output port 35. A circular shaft 33 is fixedly connected to the inner and outer walls of the conveyor box 31 with spiral blades 34. The mixing and crushing motor 22 and the conveying motor 32 are both fixedly installed on the top of the mixing and crushing box 21 and the outer left wall of the conveyor box 31 respectively through the frame. The mixing and crushing motor 22 and the conveying motor 32 are both geared motors. The mixing and crushing motor 22 and the conveying motor 32 are used to provide power to the entire device. The speed of soil and fertilizer granulation is controlled by controlling the speed of the mixing and crushing motor 22 and the conveying motor 32. After the soil and fertilizer are crushed and mixed, they enter the conveyor box 31. The conveyor motor 32 is started, which drives the circular shaft 33 to rotate. The circular shaft 33 drives the spiral blade 34 to rotate, thereby conveying the material from the left side of the inner cavity of the conveyor box 31 to the right side. Under the action of the conical output port 35 on the right side of the conveyor box 31, the soil and fertilizer mixture is granulated into cylindrical particles that are quite compact, not easy to loosen, and easy to transport. The shearing guide mechanism 4 includes a long shaft 41 rotatably connected to the top of the workbench 1 via a support plate, and a pulley 42 that drives the long shaft 41 and the round shaft 33. A cutting blade 43 is fixedly connected to the outer wall of the other end of the long shaft 41. The cutting blade 43 is flush with the end of the conical output port 35 designed on the conveyor box 31. A guide ring 44 is provided on the outside of the conical output port 35 of the conveyor box 31. The guide ring 44 has guide openings symmetrically arranged near the workbench 1. The guide ring is fixedly installed on the workbench 1 via a support frame. By setting the guide ring 44, the granulated soil and fertilizer materials can be guided to the workbench 1 after cutting. At the same time, the cutting blade 43 is covered to prevent the cutting blade 43 from being exposed and causing accidental injury to the workers. While the circular shaft 33 rotates, the long shaft 41 rotates through the drive of the pulley 42. The long shaft 41 drives the cutting blades 43, which are symmetrically arranged on the outer wall of the long shaft 41, to rotate. This causes the cutting blades 43 to periodically cut the material output from the end of the conical output port 35 on the conveyor box 31. Under its own gravity, the material falls down through the arc-shaped guide ring 4, preventing it from falling from a height and causing granulation failure. This also reduces the amount of manual handling.

[0025] Working principle: The mixing and crushing motor 22 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the crushing blades 24 and the stirring blades 25 to rotate. The rotating crushing blades 24 crush the soil and fertilizer poured into the mixing and crushing box 21 to avoid uneven mixing of lumpy soil or fertilizer. The rotation of the stirring blades 25 mixes the soil and fertilizer in the box evenly to achieve the requirements of granulation. The conveyor motor 32 drives the circular shaft 33 to rotate, and the circular shaft 33 drives the spiral blade 34 to rotate, thereby conveying the material on the left side of the inner cavity of the conveyor box 31 to the right side. Under the action of the conical output port 35 on the right side of the conveyor box 31, the soil and fertilizer mixture is granulated into a cylindrical shape, which is quite compact, not easy to loosen, and easy to transport. Driven by the pulley 42, the round shaft 33 drives the long shaft 41 to rotate, and the long shaft 41 drives the cutting blade 43 to rotate. This causes the cutting blade 43 to periodically cut the material output from the end of the conical output port 35 on the conveyor box 31. Under its own gravity, the material falls down through the arc-shaped guide ring 4, preventing it from falling from a height and causing granulation failure. This also reduces the amount of manual handling and covers the cutting blade 43 to prevent workers from accidentally touching it and causing injury.
