Description
Technical Field
[0001] This utility model relates to the field of fertilizer mixing technology, specifically a fertilizer mixing device. Background Technology
[0002] In the process of crop production, fertilizers are needed to provide the nutrients required for crop growth. At the same time, fertilizers can also improve soil fertility. In the process of fertilizer production, a mixing device is needed to evenly mix the various substances in the fertilizer together for easy use later. In the process of fertilizer preparation, raw materials such as superphosphate and urea are required. During preparation, the staff first pours the various raw materials into the mixing box through the feeding hopper, and then starts the motor to drive the rotation of the stirring shaft to achieve the purpose of mixing.
[0003] A Chinese patent (publication number: CN220091216U) discloses a fertilizer mixing device, relating to the field of fertilizer mixing technology. The device includes a mixing chamber with a feed hopper at the top and a discharge hopper at the bottom. A drive motor is connected to the inner wall of the bottom of the mixing chamber, and a stirring shaft is mounted on the upper side of the drive motor. A sleeve block is connected to the top of the feed hopper, and support frames are symmetrically arranged below the sleeve block. Each support frame contains a pressing roller. This invention, by incorporating support frames and pressing rollers, allows the raw materials to be pressed to the same size during use, ensuring uniform mixing and effectively improving fertilizer preparation efficiency and the quality of the finished fertilizer. A filter screen and a pressing roller are also included; during use, the connecting frame and pressing roller work together to further press the raw materials, ensuring thorough mixing.
[0004] During the use of the above equipment, the fertilizer can be crushed in advance by the set pressing roller, and then the crushed fertilizer is filtered by the filter screen to make the fertilizer particles uniform in size and thus better mix. However, during the filtration process, if the feeding speed is too fast, some particles with the same size as the filter screen pores are easily stuck in the filter screen, which affects the filtration effect of the filter screen and the subsequent mixing efficiency.

[0005] The purpose of this invention is to provide a fertilizer mixing device to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a fertilizer mixing device, including a mixing box and two symmetrical crushing rollers rotatably connected within the mixing box.
[0007] The filter frame is installed inside the mixing tank and can slide horizontally along the width of the mixing tank.
[0008] The lifting frame is installed inside the mixing box and can slide vertically along the length of the mixing box. The lifting frame is equipped with multiple protrusions arranged in a rectangular array. The inner diameter of the protrusions is matched with the aperture of the filter frame.
[0009] The first cam is rotatably connected inside the mixing box. When the first cam rotates, it can intermittently contact the lifting frame and abut against the vertical sliding piercing mesh hole of the filter frame of the lifting frame.
[0010] The first return spring is connected to the bottom of the lifting frame and is used in conjunction with the first cam to allow the lifting frame to slide vertically back and forth.
[0011] Furthermore, the mixing tank is also equipped with a drive assembly for driving the filter frame to slide horizontally, including,
[0012] The second cam is rotatably connected to one side of the mixing box, and an abutment plate is rotatably connected to one side of the filter frame. One end of the abutment plate extends to the outside of the mixing box, and the second cam intermittently contacts the abutment plate when it rotates.
[0013] The second return spring is connected to the contact plate at one end and to the outer surface of the mixing box at the other end.
[0014] Furthermore, the mixing tank is also equipped with a linkage component on its exterior, including,
[0015] The first drive gear is coaxially arranged with the second cam;
[0016] The second drive gear is coaxially arranged with the first cam. A drive motor is connected to the mixing box. The drive end of the drive motor is connected to a turntable. A connecting rod is rotatably connected to the turntable. The other end of the connecting rod is rotatably connected to a transmission rack.
[0017] As the turntable rotates, the transmission rack intermittently meshes with the second drive gear and the first drive gear in sequence.
[0018] Furthermore, there are at least two first reset springs, which are symmetrically arranged on both sides of the lifting frame. A first mounting plate is connected inside the mixing box, and the end of the first reset spring away from the lifting frame is connected to the top of the first mounting plate.
[0019] Furthermore, at least two second mounting plates are connected inside the mixing box, and a guide rod is slidably connected to the bottom of the second mounting plate, with the other end of the guide rod connected to the filter frame.
[0020] Furthermore, a limiting rod is connected to one side of the transmission rack, and the limiting rod is slidably connected to the mixing box, and the mixing box is provided with a sliding groove for the limiting rod to slide.
[0021] Furthermore, a stirring rack is rotatably connected inside the mixing tank, and a servo motor is connected to one side of the mixing tank. The drive end of the servo motor is connected to one end of the stirring rack.
[0022] Furthermore, the top of the mixing tank is connected to at least two feed pipes, the bottom of the mixing tank is connected to a discharge pipe, and an electronic valve is installed at the discharge pipe.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] 1. The crushing roller effectively crushes the incoming fertilizer, facilitating subsequent processing. Secondly, the filter frame screens and filters the crushed fertilizer, ensuring relatively uniform fertilizer particles entering later stages. By periodically activating the first cam, the lifting frame moves vertically, promptly ejecting fertilizer particles clogging the mesh, ensuring unobstructed flow and maintaining continuous and effective filtration. The first reset spring provides a reset effect, allowing the lifting frame to return to its original position, achieving cyclic cleaning and overall improving the quality and efficiency of fertilizer blending.
[0025] 2. By driving the second cam to rotate, it interacts with the contact plate to cause the filter frame to slide and shake horizontally. In this way, the entire filter frame can fully contact the fertilizer, and the filter holes in each part can be effectively utilized, improving the filtration efficiency. At the same time, the second return spring ensures that the filter frame can move back and forth, achieving continuous and efficient filtration.
[0026] 3. By starting the drive motor, the lifting frame can pierce and the filter frame can shake separately, effectively avoiding motion interference. The transmission rack meshes with the first and second drive gears, driving the first and second cams to rotate, causing the lifting frame and filter frame to work in sequence, which can effectively perform the filtering and cleaning functions.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] Please see Figure 1-5 This utility model provides a technical solution: a fertilizer mixing device, comprising a mixing box 1 and two symmetrical crushing rollers 2 rotatably connected within the mixing box 1, including...
[0035] The filter frame 301 is set inside the mixing box 1 and can slide horizontally along the width direction of the mixing box 1.
[0036] The lifting frame 302 is installed inside the mixing box 1 and can slide vertically along the length of the mixing box 1. The lifting frame 302 is provided with multiple protrusions arranged in a rectangular array. The inner diameter of the protrusions is adapted to the aperture of the filter frame 301.
[0037] The first cam 303 is rotatably connected inside the mixing box 1. When the first cam 303 rotates, it can intermittently contact the lifting frame 302 and abut against the vertical sliding piercing mesh hole of the filter frame 301 of the lifting frame 302.
[0038] The first return spring 304 is connected to the bottom of the lifting frame 302 and is used in conjunction with the first cam 303 to allow the lifting frame 302 to slide vertically back and forth.
[0039] It should be noted that the cross-section of the filter frame 301 is trapezoidal to prevent fertilizer from scattering when it falls.
[0040] In practice, the crushing roller 2 is first used to crush the incoming fertilizer. The crushed fertilizer falls into the filter frame 301, where it filters the fertilizer. However, the mesh may become clogged during this process. To address this, the first cam 303 is activated periodically to drive the lifting frame 302 to move vertically intermittently. During this vertical movement, the lifting frame 302 contacts the filter frame 301, which pushes out any fertilizer particles that may be clogged in the mesh of the filter frame 301, ensuring the mesh remains clear and allowing the filter frame 301 to perform continuous and effective filtration. During this process, the first return spring 304 provides a reset effect, allowing the lifting frame 302 to return to its original position.
[0041] See Figure 2 and Figure 4 The mixing tank 1 is also equipped with a drive assembly for the horizontal sliding of the filter frame 301, including,
[0042] The second cam 401 is rotatably connected to one side of the mixing box 1. The filter frame 301 is rotatably connected to one side of the abutment plate 402. One end of the abutment plate 402 extends to the outside of the mixing box 1. When the second cam 401 rotates, it intermittently abuts against the abutment plate 402.
[0043] The second return spring 403 is connected to the contact plate 402, and the other end is connected to the outer surface of the mixing box 1.
[0044] In specific implementation, if the filter frame 301 remains stationary during the filtration process, only the middle part of the filter frame 301 will contact the fertilizer, and the filter holes on both sides will be wasted, resulting in low filtration efficiency. Therefore, during the filtration process, the second cam 401 can be driven to rotate, so that the second cam 401 continuously abuts against the abutment plate 402, thereby causing the abutment plate 402 to drive the filter frame 301 to slide horizontally and shake, thereby improving the filtration efficiency. The second return spring 403 set in this process facilitates the reciprocating movement of the filter frame 301.
[0045] See Figure 1 and Figure 5 The mixing tank 1 is also equipped with a linkage component on its exterior, including,
[0046] The first drive gear 501 is coaxially arranged with the second cam 401;
[0047] The second drive gear 502 is coaxially arranged with the first cam 303. A drive motor is connected to the mixing box 1. The drive end of the drive motor is connected to the turntable 503. A connecting rod 504 is rotatably connected to the turntable 503. The other end of the connecting rod 504 is rotatably connected to the transmission rack 505.
[0048] When the turntable 503 rotates, the transmission rack 505 intermittently meshes with the second drive gear 502 and the first drive gear 501 in sequence.
[0049] In practice, starting the drive motor can drive the second drive gear 502 to rotate. During the rotation of the second drive gear 502, one end of the connecting rod 504 can rotate synchronously, causing the connecting rod 504 to pull the transmission rack 505 to move back and forth. During the reciprocating movement, the transmission rack 505 can continuously mesh with the second drive gear 502 and the first drive gear 501, thereby driving the first cam 303 and the second cam 401 to rotate. That is, when the lifting frame 302 performs the piercing action, the filter frame 301 continuously moves. However, when the filter frame 301 sways left and right, the lifting frame 302 will not perform the piercing action, thus avoiding motion interference.
[0050] See Figure 3 There are at least two first return springs 304, which are symmetrically arranged on both sides of the lifting frame 302. A first mounting plate 6 is connected inside the mixing box 1. The end of the first return spring 304 away from the lifting frame 302 is connected to the top of the first mounting plate 6.
[0051] In practice, the first mounting plate 6 facilitates the installation of the first reset spring 304, and the presence of two first reset springs 304 improves the stability of the filter frame 301 during puncture.
[0052] refer to Figure 4 The mixing box 1 is connected to at least two second mounting plates 7. The bottom of the second mounting plate 7 is slidably connected to a guide rod 8, and the other end of the guide rod 8 is connected to the filter frame 301.
[0053] In practice, the guide rod 8 can limit and guide the sliding of the filter frame 301, further improving the stability of the filter frame 301 during the sliding process.
[0054] refer to Figure 5 A limit rod 9 is connected to one side of the transmission rack 505. The limit rod 9 is slidably connected to the mixing box 1. The mixing box 1 has a groove for the limit rod 9 to slide.
[0055] In practice, the limiting rod 9 can limit and guide the movement of the transmission rack 505, further improving the stability of the transmission rack 505 during the sliding process.
[0056] refer to Figure 2 A mixing rack 10 is rotatably connected inside the mixing tank 1. A servo motor 11 is connected to one side of the mixing tank 1, and the drive end of the servo motor 11 is connected to one end of the mixing rack 10.
[0057] In practice, the mixing rack 10 can mix the fertilizer, and the servo motor 11 can drive the mixing rack 10 to rotate.
[0058] refer to Figure 1 The top of the mixing tank 1 is connected to at least two feed pipes, and the bottom of the mixing tank 1 is connected to a discharge pipe, with an electronic valve installed at the discharge pipe.
[0059] In practice, the multiple feed pipes facilitate the simultaneous addition of various fertilizers, and the discharge pipes facilitate the removal of materials.
[0060] Working principle: First, the crushing roller 2 crushes the incoming fertilizer. The crushed fertilizer falls into the filter frame 301, where it filters the fertilizer. However, the mesh may become clogged during this process. To address this, the first cam 303 is activated periodically, causing the lifting frame 302 to move vertically intermittently. During this vertical movement, the lifting frame 302 contacts the filter frame 301, pushing out any fertilizer particles that may be clogged in the mesh, ensuring the mesh remains clear and allowing the filter frame 301 to continuously and effectively perform filtration. During this process, the first return spring 304 provides a reset effect, allowing the lifting frame 302 to return to its original position.
[0061] During the filtration process of the filter frame 301, if the filter frame 301 remains stationary, only the middle part of the filter frame 301 will come into contact with the fertilizer, and the filter holes on both sides will be wasted, resulting in low filtration efficiency. Therefore, during the filtration process of the filter frame 301, the second cam 401 can be driven to rotate, so that the second cam 401 continuously abuts against the abutment plate 402, thereby causing the abutment plate 402 to drive the filter frame 301 to slide horizontally and shake, thereby improving the filtration efficiency. The second reset spring 403 set in this process facilitates the reciprocating movement of the filter frame 301.
[0062] Starting the drive motor can drive the second drive gear 502 to rotate. During the rotation of the second drive gear 502, it can drive one end of the connecting rod 504 to rotate synchronously, causing the connecting rod 504 to pull the transmission rack 505 to move back and forth. During the reciprocating movement, the transmission rack 505 can continuously mesh with the second drive gear 502 and the first drive gear 501, thereby driving the first cam 303 and the second cam 401 to rotate. That is, when the lifting frame 302 performs the piercing action, the filter frame 301 continuously moves. However, when the filter frame 301 sways left and right, the lifting frame 302 will not perform the piercing action, thus avoiding motion interference.
