Abstract
Description
Technical Field
[0001] This invention belongs to the field of fertilizer production and processing technology, and in particular relates to an automatic batching system for fertilizer production. Background Technology
[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material foundations of agricultural production. Existing new fertilizers mainly include compound fertilizers, organic fertilizers, organic-inorganic compound fertilizers, microbial fertilizers, and controlled-release fertilizers. Among them, compound fertilizers are one of the most common fertilizers. Compound fertilizers are made by mixing multiple raw materials, so a batching and mixing device is required.
[0003] Currently, there are still some problems with the actual use of the mixing and batching device. First, fertilizers are usually mixed in advance, and then multiple raw materials are poured into the mixing device at one time for mixing. Since a large amount of raw materials are poured in at one time, the mixing time is too long and the mixing effect is not good. In addition, the finished waste material after mixing will contain a lot of dust when it is discharged. The dust will be dispersed into the air during the fertilizer transportation process, thus causing environmental pollution in the workshop. Summary of the Invention
[0004] This invention provides an automatic batching system for fertilizer production, which aims to solve the problems of long mixing time, insufficient mixing, and dust pollution caused by material discharge.
[0005] This invention is implemented as follows: an automatic batching system for fertilizer production includes a base plate; a support frame is mounted on the upper end of the base plate, and a batching box is mounted on the upper end of the support frame. The batching box is shaped like an inverted frustum. Feed troughs are arranged in a circular array along the top edge of the batching box, and a discharge trough is provided at the bottom of the batching box. A storage box is correspondingly mounted above the upper end of the feed troughs. A control frame is mounted below the discharge port of the storage box. An electric cylinder is mounted on the side wall of the control frame. A motor is mounted at the top center of the batching box. The output shaft of the motor extends into the interior of the batching box and is connected to a rotating shaft. A stirring blade is mounted on the side wall of the rotating shaft. A vacuum cleaner fan is installed on the side wall of the support frame. The air inlet and outlet of the vacuum cleaner fan are both connected to air ducts. The other end of the air inlet duct of the vacuum cleaner fan is connected to the side wall of the discharge trough, and the other end of the air outlet duct of the vacuum cleaner fan is connected to the dust collection trough. The side wall of the discharge trough is provided with an opening that communicates with the air duct, and a mesh is installed at the opening. A connecting shaft is installed at the bottom of the rotating shaft, and a connecting plate is connected to the side wall of the connecting shaft. The other end of the connecting plate is connected to a scraper, and the scraper is in contact with the surface of the mesh. An air outlet trough is provided at the top of the dust collection trough, and a fixing ring is installed on the inner side wall of the air outlet trough. A mesh is installed on the inner side of the fixing ring.
[0006] Preferably, a bracket is installed on the top of the dust collection trough, and a baffle plate is hinged to the top of the bracket. The baffle plate is located diagonally above the air outlet trough. A striking pin is installed on the lower side of the baffle plate, and the striking pin is located above the mesh screen. A rubber ball is installed on the top of the bracket, and the rubber ball is located on the back side of the baffle plate.
[0007] Preferably, the fixing ring slides down and is embedded into the inner side wall of the air outlet channel of the dust collection tank. A positioning frame is installed on the outer side wall of the air outlet channel of the dust collection tank. The positioning frame has a groove inside, and a locking block is slidably installed in the groove. A spring is installed in the groove of the positioning frame, and the movable end of the spring is connected to the locking block. The outer side wall of the fixing ring has a slot that matches the locking block. A push block is installed on the top of the locking block, and the push block is located outside the positioning frame.
[0008] Preferably, the mesh is made of linen and is pressed and fixed to the inside of the fixing ring.
[0009] Preferably, a collection box is placed inside the dust collection trough, the outer wall of the collection box is in contact with the inner wall of the dust collection trough, and pulleys are installed around the bottom of the collection box.
[0010] Preferably, a spiral blade is installed on the outer side of the connecting shaft, and the spiral blade is located at the connection between the discharge trough and the bottom of the batching box.
[0011] Preferably, the inner side of the material control frame is provided with a sliding groove, and a baffle plate is slidably installed in the sliding groove. The output shaft of the electric cylinder extends into the interior of the material control frame and is connected to the side wall of the baffle plate.
[0012] Preferably, the stirring blades are provided in two sets, and the two sets of stirring blades are distributed vertically with the upper side being longer than the lower side.
[0013] Compared with the prior art, the embodiments of this application have the following main advantages: By setting the mixing bin to an inverted frustum shape, the raw materials will collide with the inner wall of the mixing bin after falling in. The curved inner wall will cause the materials in each storage bin to flow towards the center of the mixing bin after falling in. The materials that collide with each other will be fully mixed. The mixing blades can be used to assist in mixing the raw materials. On the other hand, the high-speed rotating mixing blades can break up the clumps of raw materials and make them fully mixed. The dust suction fan can draw in the dust generated during the mixing of raw materials by generating suction from the discharge chute, so as to prevent dust from being discharged with the finished fertilizer and causing pollution. By installing a screen, the finished fertilizer can be prevented from being sucked into the air duct. By installing a scraper, the rotating scraper can remove larger particles that have accumulated and adhered to the surface of the screen, ensuring stable ventilation of the screen and thus ensuring that the device can remove dust normally and effectively for a long time. By installing a baffle plate and rubber balls, the impact pin can repeatedly hit and vibrate the screen, thereby achieving automatic cleaning of the screen and ensuring stable and effective ventilation and dust removal of the dust collection trough for a long time. The spiral blades push the finished fertilizer at the discharge chute, thus clearing blockages and preventing clogging. The electric cylinder, once activated, pushes and pulls the baffle plate horizontally, allowing the control rack to have openings of varying heights and sizes to adjust the discharge speed of the storage bin and achieve precise raw material proportioning.

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0017] This invention provides an automatic batching system for fertilizer production, such as... Figure 1-7As shown, the system includes a base plate 1, a support frame 2 mounted on the upper end of the base plate 1, a mixing box 3 mounted on the upper end of the support frame 2, the mixing box 3 being shaped like an inverted frustum, a feeding trough 4 arranged in a circular array at the top edge of the mixing box 3, a discharge trough 5 at the bottom of the mixing box 3, a storage box 6 mounted on the upper end of the feeding trough 4, a control frame 7 mounted below the discharge port of the storage box 6, an electric cylinder 8 mounted on the side wall of the control frame 7, a motor 9 mounted at the top center of the mixing box 3, the output shaft of the motor 9 extending into the interior of the mixing box 3 and connected to a rotating shaft 10, a stirring blade 11 mounted on the side wall of the rotating shaft 10, a dust collector 12 mounted on the side wall of the support frame 2, and air ducts 13 connected to both the air inlet and outlet of the dust collector 12. The other end of pipe 13 is connected to the side wall of discharge trough 5. The other end of the air outlet pipe 13 of the dust collector 12 is connected to dust collection trough 14. The side wall of discharge trough 5 is provided with an opening communicating with pipe 13, and a mesh 15 is installed at the opening. A connecting shaft 16 is installed at the bottom of rotating shaft 10. A connecting plate 17 is connected to the side wall of connecting shaft 16. A scraper 18 is connected to the other end of connecting plate 17. The scraper 18 is in contact with the surface of mesh 15. An air outlet trough is provided at the top of dust collection trough 14, and a fixing ring 19 is installed on the inner side wall of the air outlet trough. A mesh 20 is installed on the inner side of fixing ring 19. When the device is in use, various raw materials are stored in storage box 6. When batching is required, the electric cylinder 8 can be activated to make the material control rack 7 release the material. At this time, the raw material falls from the feed trough 4 into the batching trough. Inside the mixing tank 3, by setting the mixing tank 3 in the shape of an inverted frustum, when the raw materials fall in, they will collide with the inner wall of the mixing tank 3. The arc-shaped inner wall will cause the materials in each storage tank 6 to flow towards the center of the mixing tank 3 after falling in. The materials that collide with each other will be thoroughly mixed. By setting up stirring blades 11, the mixing tank 3 can start the motor 9 during the mixing process. The motor 9 drives the stirring blades 11 to rotate through the rotating shaft 10. The rotating stirring blades 11 can further disperse the raw materials. On the other hand, the high-speed rotating stirring blades 11 can break up the clumps of raw materials, so that they are thoroughly mixed. The mixed product is discharged from the discharge chute 5 under the action of gravity. The mixing tank 3 can start the dust extraction fan 12 during the mixing process. The dust extraction fan 12 creates negative pressure inside the discharge chute 5 through the air duct 13. This system effectively draws in dust generated during raw material mixing, preventing it from being discharged with the finished fertilizer and causing pollution. A screen 15 prevents the finished fertilizer from being sucked into the duct 13. A scraper 18 is installed; when the rotating shaft 10 drives the mixing blades 11, the connecting shaft 16 at its bottom drives the scraper 18 to rotate via the connecting plate 17. The rotating scraper 18 removes larger particles accumulated on the surface of the screen 15, ensuring stable ventilation and thus guaranteeing long-term, effective dust removal. A mesh 20 allows air and dust drawn in by the dust collector 12 to fall into the dust collection trough 14, while the air exits from the air outlet at the top of the dust collection trough 14. The mesh 20 prevents dust from being dispersed into the air.This effectively retains the dust inside the dust collection tank 14.
[0018] A bracket 21 is installed on the top of the dust collection trough 14, and a baffle 22 is hinged to the top of the bracket 21. The baffle 22 is located diagonally above the air outlet duct. A striker 23 is installed on the lower side of the baffle 22, and the striker 23 is located above the mesh 20. A rubber ball 31 is installed on the top of the bracket 21, and the rubber ball 31 is located on the back side of the baffle 22. With the baffle 22 and striker 23 in place, after the air in the dust collection trough 14 is blown out of the air outlet duct, the baffle 22 rotates counterclockwise under the action of the wind until the baffle 22 touches the rubber ball 31. Under the action of elasticity, it rotates clockwise again. The elasticity generated by the rubber ball 31 causes the impact pin 23 on the lower side of the wind deflector 22 to strike the screen 20. The screen 20 vibrates briefly after being subjected to force. The screen 20 deforms after being subjected to force, and through the reaction force and wind force, the wind deflector 22 rotates counterclockwise again. This repeated action allows the impact pin 23 to periodically strike the screen 20. This setting can shake off the dust particles adsorbed on the lower surface of the screen 20. This setting can realize the automatic cleaning of the screen 20, thereby ensuring that the dust collection tank 14 has stable and effective ventilation and dust collection for a long time.
[0019] The fixing ring 19 slides downwards into the inner wall of the air outlet duct of the dust collection trough 14. A positioning frame 24 is installed on the outer wall of the air outlet duct of the dust collection trough 14. The positioning frame 24 has a groove inside, and a locking block 25 is slidably installed in the groove. A spring 26 is installed in the groove of the positioning frame 24, and the movable end of the spring 26 is connected to the locking block 25. The outer wall of the fixing ring 19 has a slot that matches the locking block 25. A push block 27 is installed on the top of the locking block 25, and the push block 27 is located outside the positioning frame 24. With the positioning bracket 24 in place, the fixing ring 19 on the outer side of the mesh 20 is inserted downwards from the top of the air outlet duct, and the locking block 25 inside the positioning bracket 24 is locked into the slot on the side wall of the fixing ring 19 under the elastic force of the spring 26, thereby fixing the fixing ring 19. The locking block 25 can be pushed out of the slot of the fixing ring 19 by pushing the push block 27, so that the fixing ring 19 and the mesh 20 can be removed as a whole. This installation method makes the disassembly and replacement of the mesh 20 more convenient and facilitates the replacement of the new mesh 20 in the future.
[0020] The mesh 20 is made of linen and is pressed and fixed to the inside of the fixing ring 19. The linen mesh 20 has good elasticity, which makes it easy to work with the impact pin 23 for dust removal. At the same time, the linen mesh 20 is inexpensive and has low replacement cost.
[0021] A collection box 28 is placed inside the dust collection tank 14. The outer wall of the collection box 28 is in contact with the inner wall of the dust collection tank 14. The bottom of the collection box 28 is equipped with pulleys. By setting up the collection box 28, the collection box 28 is slid into the dust collection tank 14 through the pulleys to collect dust. This setting facilitates the centralized removal of dust in the dust collection tank 14 and subsequent processing.
[0022] A spiral blade 29 is installed on the outer side of the connecting shaft 16. The spiral blade 29 is located at the bottom connection between the discharge chute 5 and the batching box 3. With the spiral blade 29 installed, the connecting shaft 16 rotates along with the rotating shaft 10, while driving the spiral blade 29 to rotate. The rotating spiral blade 29 can assist in pushing and pulling the waste material, thereby avoiding blockage.
[0023] The inner side of the material control rack 7 is provided with a sliding groove, and a baffle plate 30 is slidably installed in the sliding groove. The output shaft of the electric cylinder 8 extends into the interior of the material control rack 7 and is connected to the side wall of the baffle plate 30. With the material control rack 7 provided, the electric cylinder 8 will push and pull the baffle plate 30 horizontally after starting. This setting allows the material control rack 7 to present openings of different heights and sizes, thereby changing the feeding speed of the storage box 6 and realizing the quantitative proportion of raw materials.
[0024] Two sets of stirring blades 11 are provided, which are distributed vertically with the upper side being longer than the lower side. By providing two sets of stirring blades 11, the stirring range and the range of breaking up agglomerated raw materials can be increased, thereby further improving the mixing effect of the raw materials.
