Description

Technical Field

[0001] The utility model relates to the technical field of slow-release fertilizers, in particular to a mixing device for the production of slow-release fertilizers that can improve the slow-release effect. Background Technique

[0002] The mixing device for the production of slow-release fertilizers is a device specifically used for mixing the raw materials for the production of slow-release fertilizers. This device usually includes key components such as a fixed frame, a motor, a discharge port, and a box body. Among them, the motor drives the rotation of the rotating shaft, and drives the stirring rod to rotate through a transmission mechanism such as gears, so as to realize the mixing of the raw materials.

[0003] In order to improve the slow-release effect, a controlled-release mechanism is installed inside most of the mixing devices for the production of slow-release fertilizers: The controlled-release mechanism is a key device for the production of slow-release fertilizers. By selecting a suitable controlled-release mechanism (such as a chemical reaction controlled-release mechanism, a film coating controlled-release mechanism, a microbial controlled-release mechanism, etc.), the release rate and time of nutrients in the fertilizer can be controlled, so as to optimize the slow-release effect. And such a mixing device for the production of slow-release fertilizers equipped with a controlled-release mechanism can be called a mixing device for the production of slow-release fertilizers that can improve the slow-release effect.

[0004] However, the existing controlled-release materials are polymer coating materials (resin, rubber), sulfur coating, minerals, etc., and their own hardness is relatively high. After adding these controlled-release materials to the inside of the equipment, it takes a lot of time for the rotating stirring blades alone to completely mix them with the chemical fertilizer raw materials, thus affecting the production efficiency of slow-release fertilizers; Therefore, it does not meet the existing needs, and for this reason, we propose a mixing device for the production of slow-release fertilizers that can improve the slow-release effect. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a mixing device for the production of slow-release fertilizers that can improve the slow-release effect, so as to solve the problems raised in the above background technique that the existing controlled-release materials are polymer coating materials (resin, rubber), sulfur coating, minerals, etc., and their own hardness is relatively high. After adding these controlled-release materials to the inside of the equipment, it takes a lot of time for the rotating stirring blades alone to completely mix them with the chemical fertilizer raw materials, thus affecting the production efficiency of slow-release fertilizers.

[0006] To achieve the above object, the present utility model provides the following technical solutions: a mixing device for the production of slow-release fertilizers capable of improving the slow-release effect, including a controlled-release fertilizer mixer. On one side of the outer surface of the controlled-release fertilizer mixer, a stepping motor is fixedly installed. The output shaft of the stepping motor is connected to a transmission rotating shaft through a coupling. On one side of the outer surface of the transmission rotating shaft, a controlled-release material pre-crushing mechanism is connected. The controlled-release material pre-crushing mechanism includes a filter screen, crushing and cutting rods, and a synchronous transmission mechanism. The filter screen is located below the crushing and cutting rods, and the filter screen can be synchronously driven to rotate while being driven to move up and down in a cycle through the synchronous transmission mechanism.

[0007] Preferably, in the middle position of the rear end face of the transmission rotating shaft, a stirring blade located inside the controlled-release fertilizer mixer is connected;

The two concave rotating shafts are respectively connected to the front and rear end faces of the crushing and cutting rods, and the first concave rotating shaft from left to right is connected in series with the transmission rotating shaft through a synchronous chain.

[0009] Preferably, one side of the outer surface of the concave rotating shaft is concave. A metal sleeve is movably sleeved at the concave part on the outer surface of the concave rotating shaft. The lower end face of the metal sleeve is connected to a connecting rod through a rotating shaft. The lower end face of the connecting rod is connected to a pushing rod through a rotating shaft, and a rubber contact pushing head is fixedly arranged on the surface of the pushing rod facing the filter screen.

[0015] 1. The utility model can drive the crushing and cutting rod to rotate through the synchronous transmission mechanism. The controlled-release material just added to the inside of the controlled-release fertilizer mixer will first contact the rotating crushing and cutting rod. The rotating crushing and cutting rod can crush the controlled-release material to cut it into smaller particles, increasing the overall surface area of the controlled-release material, thereby reducing the time required for the complete fusion between the controlled-release material and the chemical fertilizer raw materials.

One side of the outer surface of the controlled-release fertilizer mixer 1 is fixedly installed with a stepping motor 2. The output shaft of the stepping motor 2 is connected to a transmission rotating shaft 3 through a coupling. One side of the outer surface of the transmission rotating shaft 3 is connected with a controlled-release material pre-crushing mechanism. The controlled-release material pre-crushing mechanism includes a filter screen 5, a crushing and cutting rod 6, and a synchronous transmission mechanism. The filter screen 5 is located below the crushing and cutting rod 6, and through the synchronous transmission mechanism, the filter screen 5 can be driven to move up and down cyclically while synchronously driving the crushing and cutting rod 6 to rotate.

[0025] As a preferred technical solution of this embodiment, as Figure 3 and Figure 4 shown, the middle position of the rear end face of the transmission rotating shaft 3 is connected with a stirring blade 4 located inside the controlled-release fertilizer mixer 1; when the equipment needs to be used, start the stepping motor 2, and the transmission rotating shaft 3 connected thereto and the stirring blade 4 connected to the middle position of the rear end face of the transmission rotating shaft 3 can be driven to rotate by the stepping motor 2. Then, add chemical fertilizer raw materials inside the controlled-release fertilizer mixer 1, and the added raw materials can be mixed and stirred by the rotating stirring blade 4. When the addition of chemical fertilizer raw materials is completed, add controlled-release materials;

[0026] The synchronous transmission mechanism includes two concave rotating shafts 8. The two concave rotating shafts 8 are respectively connected to the front and rear end faces of the crushing and cutting rod 6, and the first concave rotating shaft 8 from left to right is connected in series with the transmission rotating shaft 3 through a synchronous chain 7; during the rotation of the transmission rotating shaft 3, the concave rotating shaft 8 connected in series with it through the synchronous chain 7 and the crushing and cutting rod 6 fixed to the concave rotating shaft 8 will rotate together. The controlled-release materials just added to the inside of the controlled-release fertilizer mixer 1 will first come into contact with the rotating crushing and cutting rod 6. The rotating crushing and cutting rod 6 can crush the controlled-release materials to cut them into smaller particles, increasing the overall surface area of the controlled-release materials, thereby reducing the time required for the complete fusion between the controlled-release materials and the chemical fertilizer raw materials. Through this embodiment, the production efficiency of slow-release fertilizer can be improved.

[0027] As a preferred technical solution of this embodiment, as Figure 4 shown, one side of the outer surface of the concave rotating shaft 8 is concave. A metal sleeve 9 is movably sleeved on the concave part of the outer surface of the concave rotating shaft 8. The lower end face of the metal sleeve 9 is connected to a connecting rod 10 through a rotating shaft. The lower end face of the connecting rod 10 is connected to a pushing rod 11 through a rotating shaft, and a rubber contact pushing head 13 is fixedly arranged on the surface of the pushing rod 11 facing the filter screen 5; during the rotation of the concave rotating shaft 8, the metal sleeve 9 sleeved on the concave part of the outer surface of the concave rotating shaft 8 will revolve around the top end of the concave rotating shaft 8 as the center.

[0028] A guide sleeve 12 is movably sleeved on the lower side of the outer surface of the push rod 11. One side of the outer surface of the guide sleeve 12 is fixedly provided with a support rod, and the surface of the support rod facing the inner wall of the controlled-release fertilizer mixer 1 is fixed to the inner wall of the controlled-release fertilizer mixer 1; during the revolution of the metal sleeve 9, the push rod 11 will be pulled up and down through the connecting rod 10, and through the guide sleeve 12 sleeved on the lower side of the outer surface of the push rod 11, it can ensure that the push rod 11 moves up and down while maintaining an upright state. When the push rod 11 moves downward, the rubber contact push head 13 fixed to the lower end surface of the push rod 11 will move downward accordingly.

[0029] A support plate 14 is provided below the rubber contact push head 13. Both sides of the upper end surface of the support plate 14 are connected with a plurality of springs 15, and the upper end surfaces of the springs 15 are connected to the lower end surface of the filter screen 5; the downward-moving rubber contact push head 13 will contact the filter screen 5 and push the filter screen 5 downward. When the filter screen 5 moves downward, it will squeeze the springs 15 connected thereto.

The limit head 17 fixedly sleeved on the outer surface of the guide rod 16 can limit the maximum height of the filter screen 5 to prevent it from contacting the rotating crushing and cutting rod 6;

[0031] The filter screen 5 that moves up and down can screen the cut controlled-release materials. Only when the controlled-release materials are cut into particles smaller than the size of the filter holes on the filter screen 5 can they pass through the filter screen 5 and be mixed with the chemical fertilizer raw materials located on the lower side inside the controlled-release fertilizer mixer 1. Through the above technical solution, it can be ensured that the controlled-release materials are cut into the specified size
