Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, and in particular to a flip-plate feeding mechanism for a mineral compound fertilizer production line. Background Technology

[0002] The mineral compound fertilizer production line integrates soil testing, formula customization, fertilizer production, and farmer fertilization, forming an integrated service system encompassing production, supply, sales, and application. It transforms the original single fertilizer business into a service-oriented business, fundamentally changing farmers' fertilization habits and enabling fertilization based on soil type, crop needs, and farmer requirements. This improves crop yield, enhances crop quality, and regulates soil elements, providing farmers with precise fertilization services that reduce costs and increase income.

[0003] According to Chinese Patent Publication No. CN221587301U, a flip-plate feeding mechanism for a mineral compound fertilizer production line facilitates the placement of mineral compound fertilizer raw materials through the cooperation of the feeding flip plate and the feeding plate. Two baffles limit the mineral compound raw materials on the feeding flip plate. Two lifting seats facilitate the simultaneous movement of two lower pressure plates on the upper side of the feeding flip plate, so that the mineral compound fertilizer raw materials on the feeding flip plate can be pressed down through the cooperation of the two lower pressure plates. Thus, the cooperation of the two baffles and the two lower pressure plates reduces the falling of mineral compound raw materials during the movement of the feeding flip plate. The drive component facilitates the simultaneous rotation of the feeding flip plate, the feeding plate, and the two baffles, so that the mineral compound fertilizer raw materials can be poured into the feeding hopper, thereby allowing the mineral compound fertilizer raw materials to enter the raw material silo through the feeding hopper and the feeding bin.

[0004] In this application, the feeding flap is tilted before feeding. After the raw material is added into the feeding flap, it slides downward under its own weight. Even with the cooperation of the lower pressure plate, the raw material may still slide and fall. At the same time, during the process of adding the raw material into the feeding flap, the raw material will pile up under its own weight, which makes it difficult for the lower pressure plate to limit the raw material. Therefore, a flap feeding mechanism for a mineral compound fertilizer production line is proposed to solve the above problems. Utility Model Content

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1-6 As shown, the present invention proposes a flip-plate feeding mechanism for a mineral compound fertilizer production line, including a feeding bin 1, a raw material bin 2, and a feeding hopper 3. The feeding hopper 3 is installed on one side of the raw material bin 2, the feeding bin 1 is located at the top of the feeding hopper 3, a feeding port is opened on the right side of the feeding bin 1, and a flip-plate feeding structure 4 is provided on the right side of the feeding hopper 3.

[0028] In this utility model, the material can be lifted and tipped by the flip-plate feeding structure 4 and fed into the inside of the feeding bin 1 through the feeding port, and then into the inside of the raw material bin 2 through the feeding hopper 3. The flip-plate feeding structure 4 can more conveniently and quickly add the raw material into the raw material bin 2, ensuring the stability of the raw material when it is added into the raw material bin 2, and minimizing the possibility of the raw material falling into the raw material bin 2.

[0029] In an optional embodiment, the tipping feeding structure 4 includes vertical plates 41 installed on the front and back of the feeding bin 1. Two base plates 42 are respectively installed on the right side of the two vertical plates 41. Two lifting blocks 43 are arranged between the opposite sides of the two base plates 42. Lifting components 44 are provided on the top of the two base plates 42. The two lifting components 44 are respectively connected to the two lifting blocks 43 and are used to drive the two lifting blocks 43 to lift. A support plate 45 is installed between the opposite sides of the two lifting blocks 43. A feeding tipping bucket 46 is placed on the top of the support plate 45. A rotating component 47 is arranged between the opposite sides of the two lifting blocks 43. The rotating component 47 is connected to the feeding tipping bucket 46 and is used to drive the feeding tipping bucket 46 to rotate.

[0030] Two sets of lifting components 44 can be installed on the two vertical plates 41 and the base plate 42 respectively. The raw materials of compound fertilizer can be placed in the two feeding hoppers 46. After being placed, the two sets of lifting components 44 can drive the two lifting blocks 43 to move upward. The two lifting blocks 43 will drive the rotating component 47 and the support plate 45 to move upward. The support plate 45 will drive the feeding hopper 46 to move upward. The feeding hopper 46 will drive the raw materials to move upward. When the feeding hopper 46 moves above the feeding bin 1, the rotating component 47 can drive the feeding hopper 46 to rotate.

[0031] A discharge port is provided on the left side of the feeding hopper 46. A baffle plate 48 is provided inside the discharge port, and a torsion component 49 is provided inside the discharge port. The discharge port is connected to the baffle plate 48 through the torsion component 49, and the baffle plate 48 is adapted to the discharge port.

[0032] When the feeding hopper 46 rotates, the material will move to the left side of the feeding hopper 46 under its gravity. At this time, the material will squeeze the baffle plate 48. Then, under the action of the torsion component 49, the baffle plate 48 will flip, so that the raw material will be discharged through the discharge port.

[0033] The left side of the feeding hopper 46 corresponds to the right side of the feeding bin 1. The width of the feeding hopper 46 is smaller than the width of the feeding port. Because the rotating component 47 is located at the bottom of the feeding hopper 46, when the feeding hopper 46 rotates through the rotating component 47, the left side of the feeding hopper 46 will move to the top of the feeding bin 1. At this time, the raw material discharged through the discharge port will fall directly into the feeding bin 1 and be sent into the feeding bin 1 through the feeding hopper 3.

[0034] In an optional embodiment, the two lifting assemblies 44 include vertical rods 441 respectively mounted on the top of the two base plates 42. Each vertical rod 441 has a lifting groove on its opposite side. Each vertical rod 441 has a first servo motor 442 mounted on its top. The output shafts of the two first servo motors 442 are each fitted with threaded rods 443 extending into the lifting groove. The two threaded rods 443 are rotatably connected to the inner bottom wall of the two lifting grooves. Each threaded rod 443 has a threaded block 444 threadedly connected to its outer side. The opposite side of the two threaded blocks 444 is connected to the opposite side of the two lifting blocks 43.

[0035] When it is necessary to lift the feeding hopper 46, the two first servo motors 442 are started. The two output shafts of the first servo motors 442 will drive the two threaded rods 443 to rotate respectively. Since the lifting groove and the threaded block 444 are both square, the two threaded blocks 444 will not rotate. When the two threaded rods 443 rotate, under the action of the thread thrust, the two threaded rods 443 will drive the two threaded blocks 444 to move upward respectively. The two threaded blocks 444 will drive the two lifting blocks 43 to move upward respectively. The two lifting blocks 43 will drive the support plate 45 to move upward. The support plate 45 will drive the feeding hopper 46 to move upward.

[0036] The two first servo motors 442 have the same parameters. The two first servo motors 442 are controlled by a vector frequency converter to achieve master-slave control. The master-slave control is a speed closed-loop control with feedback from the servo encoder to achieve synchronous movement of the two first servo motors 442. For details, please refer to "Real-time Synchronous Control Technology of Dual Motor Drive Lifting Mechanism". It will not be elaborated in this application document.

[0037] In an optional embodiment, the rotating assembly 47 includes an L-shaped plate 471 respectively mounted on opposite sides of the two lifting blocks 43. A second servo motor 472 is mounted on the rear side wall of the inner cavity of the front L-shaped plate 471. The output shaft of the second servo motor 472 is mounted with a rotating shaft 473 extending between opposite sides of the two L-shaped plates 471. The other end of the rotating shaft 473 is rotatably connected to the front side of the front L-shaped plate 471. Two connecting blocks 474 are mounted on the outer side of the rotating shaft 473. The tops of the two connecting blocks 474 are connected to the bottom of the feeding hopper 46.

[0038] When the feeding hopper 46 moves upward and reaches above the feeding bin 1, the second servo motor 472 is activated. The output shaft of the second servo motor 472 will drive the rotating shaft 473 to rotate. The rotating shaft 473 will drive the two connecting blocks 474 to rotate. The two connecting blocks 474 will drive the feeding hopper 46 to rotate.

[0039] In an optional embodiment, the torsion assembly 49 includes mounting grooves 491 formed on the front and rear side walls of the discharge port cavity. A rotating rod 492 is rotatably connected between opposite sides of the two mounting grooves 491 cavities. A baffle plate 48 is mounted on the outside of the rotating rod 492. A torsion spring 493 is mounted on the opposite side wall of the two mounting grooves 491 cavities. The opposite sides of the two torsion springs 493 are respectively connected to the front and back of the baffle plate 48, and are both located on the outside of the rotating rod 492.

[0040] During the rotation of the feeding hopper 46, the raw material inside the feeding hopper 46 will move to the left, causing the raw material to accumulate on the left side of the feeding hopper 46. At this time, the raw material will squeeze the baffle plate 48, causing the baffle plate 48 to rotate, thereby exposing the discharge port to the outside. The raw material inside the feeding hopper 46 will fall directly into the feeding bin 1 through the discharge port.

[0041] When the baffle plate 48 rotates, it drives the rotating rod 492 to rotate. When the baffle plate 48 rotates, it drives the two torsion springs 493 to twist. When the second servo motor 472 is started in reverse, the feeding hopper 46 will rotate in the opposite direction and return to a horizontal position. At this time, the baffle plate 48 rotates in the opposite direction and is in a vertical state under the rebound force of the two torsion springs 493. At this time, the baffle plate 48 will block the discharge port to ensure the stability of the feeding hopper 46 when it is filled with materials.

[0042] In an optional embodiment, a controller is installed on the outside of the feeding hopper 1. The first servo motor 442 and the second servo motor 472 are both electrically connected to the controller, and the controller can control the first servo motor 442 and the second servo motor 472.

[0043] Working principle:

[0044] In the operation of the tilting feeding mechanism of this mineral compound fertilizer production line, the raw materials for compound fertilizer production are first added into the feeding hopper 46. At this time, the raw materials are blocked by the side wall of the feeding hopper 46 and the baffle plate 48, so that the raw materials can remain stably inside the feeding hopper 46. After the raw materials are added, the first servo motor 442 is started, which causes the two threaded blocks 444 to move upward. The two threaded blocks 444 will drive the two lifting blocks 43 to move upward, which will drive the support plate 45 to move upward, and the support plate 45 will drive the feeding hopper 46 to move upward. When the 6th motor moves above the feeding bin 1, the second servo motor 472 is activated. The output shaft of the second servo motor 472 drives the rotating shaft 473 to rotate. The rotating shaft 473 drives the two connecting blocks 474 to rotate. The two connecting blocks 474 drive the feeding hopper 46 to rotate. During the rotation of the feeding hopper 46, the raw material inside the feeding hopper 46 moves to the left, causing the raw material to accumulate on the left side of the feeding hopper 46. At this time, the raw material will squeeze the baffle plate 48, causing the baffle plate 48 to rotate, thereby exposing the discharge port to the outside. The raw material inside the feeding hopper 46 will fall directly into the feeding bin 1 through the discharge port.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
