Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing equipment technology, and in particular to a fertilizer mixing mixer. Background Technology

[0002] In modern agricultural production, fertilizer mixing is a crucial step in the production of compound fertilizers or organic-inorganic compound fertilizers. Fertilizer mixers, as core equipment for achieving uniform mixing of various materials, are widely used. Existing fertilizer mixers include a mixing tank and a mixing device installed inside the tank. However, many fertilizer raw materials, especially organic fertilizers or materials with high moisture content, have strong adhesion and poor flowability. During the mixing process, these sticky materials easily adhere to the inner wall of the mixing tank, especially in the bottom and corner areas of the tank that are difficult for the mixing device to reach, forming a layer of sticky material that is difficult to remove. This not only affects the uniformity of fertilizer mixing but also causes a large amount of material residue during discharge, resulting in waste and cross-contamination between different batches. More seriously, the fertilizer adhering to the bottom will accumulate near the discharge port, even forming an arch, thus blocking the discharge port and slowing down or even interrupting the discharge process. This seriously reduces production efficiency and often requires manual unblocking and cleaning, which increases labor intensity and poses safety hazards. Existing mixers generally lack an effective structure that can actively solve the problems of material adhesion at the bottom and blockage at the discharge port.

[0003] Therefore, this utility model proposes a fertilizer mixing mixer to overcome the shortcomings of the prior art. Utility Model Content

[0004] In view of the problems that existing fertilizer mixing mixers generally suffer from when processing viscous materials, such as severe material adhesion at the bottom of the tank and easy blockage of the discharge port leading to poor material discharge, this utility model aims to provide a fertilizer mixing mixer with an improved structure that can effectively solve the above problems.

[0005] This utility model provides a fertilizer mixing mixer, including: a mixing tank, a motor, a rotating rod and a mixing blade, as well as a connecting rod, a scraper, a groove, a triangular plate, a fixing rod, a hinge, a baffle, a fixing block, a locking post, a pull ring and a threaded sleeve.

[0006] The scraper's outline is adapted to the inner bottom of the mixing tank, and the scraper is integrated with a triangular plate for scraping up the fertilizer and a groove for collecting and guiding the fertilizer.

[0007] Furthermore, the rotating rod is fixedly connected to the scraper and the fixed rod through the connecting rod at the bottom. Under the drive of the motor, the scraper scrapes and cleans the bottom of the mixing tank, while the fixed rod clears the discharge port area. The baffle is connected to the bottom of the mixing tank through a hinge and is locked or released by a locking pin that can be inserted and removed from the fixed block.

[0008] Preferably, the scraper is a plate-shaped structure arranged radially, the triangular plate is located on the front side of the scraper facing the rotation direction, and the groove is located behind the triangular plate.

[0009] Preferably, the inner wall surface of the groove is coated with an anti-stick material layer.

[0010] Preferably, the fixing rod is rod-shaped and coaxially disposed at the bottom center of the connecting rod, with the free end of the fixing rod facing the baffle.

[0011] Preferably, there are two fixing blocks, which are welded to the outer wall of the mixing tank at intervals, and the locking pin passes through the fixing block, the baffle and the other fixing block in sequence.

[0012] Preferably, one end of the locking pin is provided with a pull ring, and the other end is provided with an external thread. The threaded sleeve has an internal thread structure and is screwed to the other end of the locking pin, for tightening and abutting against the outside of the fixing block.

[0013] Preferably, one side of the hinge is connected to the upper edge of the baffle, and the other side is connected to the bottom outlet edge of the mixing tank.

[0014] Preferably, the stirring blades are in multiple sets and are spaced apart along the axial direction of the rotating rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the technical problem in the prior art of processing sticky fertilizers, where the material adheres to the bottom of the mixing tank, is difficult to clean, and easily clogs the discharge port. It achieves the beneficial effects of automatically cleaning the tank bottom, preventing blockage, ensuring smooth discharge, and improving the applicability of the equipment. This is achieved by setting a scraper at the bottom of the rotating rod and rotating synchronously with the rotating rod, and integrating a triangular plate for scraping the material and an anti-sticking groove for guiding the material on the scraper. In addition, a fixed rod is set above the discharge port for coordinated unblocking.

[0017] 2. This utility model uses a hinged baffle and a pluggable locking pin that passes through a fixing block to lock the baffle. At the same time, a threaded sleeve is set on the locking pin for secondary fastening and a pull ring is set for easy operation. This solves the technical problems of complex structure, unreliable locking, and easy material leakage in some discharge ports in the prior art. It achieves the beneficial effects of simple discharge port structure, firm locking, convenient operation and good sealing performance. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0025] Example:

[0026] Please refer to Figures 1 to 4 This utility model provides a fertilizer mixing mixer, aiming to solve the technical problems of material sticking to the bottom of the tank, blockage of the discharge port, and incomplete discharge caused by the viscosity of the material during fertilizer mixing. Figure 1 and Figure 2As shown, the device includes a mixing tank 1, which serves as the main support for the entire apparatus. A motor 2 is fixedly mounted on the top of the mixing tank 1. A rotating rod 3 is vertically positioned inside the mixing tank 1, with its upper end connected to the output shaft of the motor 2. Stirring blades 4 are fixedly connected to the outer wall of the rotating rod 3. Multiple sets of stirring blades 4 are spaced apart along the axial direction of the rotating rod 3. A connecting rod 5 is fixed to the bottom of the rotating rod 3, and a scraper 6 is connected to the end of the connecting rod 5. The outline of the scraper 6 matches the outline of the inner bottom of the mixing tank 1. The scraper 6 has openings... The mixing tank 1 has a groove 7, the inner wall surface of which is coated with an anti-stick material layer. A triangular plate 8 is fixed on the scraper 6. A fixing rod 9 is connected to the bottom of the connecting rod 5. A baffle 11 is pivotally connected to the bottom of the mixing tank 1 via a hinge 10. Two fixing blocks 12 are welded to the outer wall of the mixing tank 1. The fixing blocks 12 have through holes. The baffle 11 is locked by inserting a locking pin 13 into the through hole of the fixing block 12. A pull ring 15 is connected to one end of the locking pin 13. The other end of the locking pin 13 has an external thread and is threaded to a threaded sleeve 14.

[0027] The material cleaning and anti-clogging component forms a stable transmission connection with the rotating rod 3 through the connecting rod 5. Please refer to the following for details. Figure 3 The core structure is described in detail below. The scraper 6 is a radially arranged plate-like structure. The outline of the scraper 6 matches the outline of the bottom inner side of the mixing tank 1, allowing it to scrape against the inner wall of the mixing tank 1 during rotation. A triangular plate 8 is fixedly connected to the front side of the scraper 6 facing the direction of rotation. The triangular plate 8 enhances the scraping ability against adhering materials. Behind the triangular plate 8, a groove 7 is formed on the scraper 6. The groove 7 collects the fertilizer scraped up by the triangular plate 8. The inner wall surface of the groove 7 is coated with an anti-sticking material layer, effectively preventing secondary adhesion of fertilizer inside the groove 7 and ensuring that the material can smoothly slide towards the discharge port. The scraper 6 is fixedly connected to the bottom end of the rotating rod 3 via a connecting rod 5. When the motor 2 is working, the rotating rod 3 drives the scraper 6, triangular plate 8, and groove 7 to rotate synchronously. This structural combination ensures that the fertilizer adhering to the bottom of the mixing tank 1 can be actively scraped up and effectively guided to the central area. Meanwhile, please refer to... Figure 1 and Figure 2 The fixing rod 9 is rod-shaped and coaxially fixed to the center of the bottom end of the connecting rod 5. The free end of the fixing rod 9 faces the baffle 11. When the scraper 6 guides the fertilizer to the center, the fixing rod 9 rotates synchronously to disturb and clear the material near the discharge port, which can effectively break the arching that the material will form and ensure smooth discharge.

[0028] Please refer to Figure 1 , Figure 2 and Figure 4The structure of the locking device can be further defined. There are two fixing blocks 12. The two fixing blocks 12 are welded to the outer wall of the mixing tank 1 at intervals and are located on both sides of the baffle 11 respectively. Each fixing block 12 is provided with a through hole, and the baffle 11 is also provided with a corresponding through hole. When the baffle 11 is closed, the through hole of the baffle 11 coincides and aligns with the through holes of the two fixing blocks 12. The locking pin 13 passes through the through hole of the fixing block 12, the through hole of the baffle 11 and the through hole of the other fixing block 12 in sequence, thereby firmly locking the baffle 11 in the closed position, as a further optimization of the locking reliability.

[0029] Please refer to Figure 4 One end of the locking post 13 is equipped with a pull ring 15, which facilitates the operator's insertion and removal of the locking post 13. The other end of the locking post 13 is equipped with an external thread, and the threaded sleeve 14 has an internal thread structure and is threaded with the other end of the locking post 13. After the locking post 13 is fully inserted, the threaded sleeve 14 is tightened so that the end face of the threaded sleeve 14 is tightened and abuts against the outside of the fixing block 12. Through the self-locking effect of the thread, the locking post 13 can be effectively prevented from loosening and slipping out under equipment vibration or accidental contact. As an optimization of the discharge action, one side of the hinge 10 is rotatably connected to the upper edge of the baffle 11, and the other side of the hinge 10 is fixedly connected to the bottom discharge port edge of the mixing tank 1. This connection method allows the baffle 11 to flip down and open by its own weight after unlocking, which facilitates the smooth discharge of fertilizer.

[0030] Working principle: When fertilizer needs to be mixed, it is fed into the inlet at the top of the mixing tank 1. The motor 2, located at the top of the mixing tank 1, is started. The motor 2 drives the rotating rod 3, which is vertically installed inside the mixing tank 1, to rotate via a transmission connection. As the rotating rod 3 rotates, multiple sets of stirring blades 4, fixed to the outer wall of the rotating rod 3, also rotate synchronously. The stirring blades 4 thoroughly shear, tumble, and stir the fertilizer inside the mixing tank 1, thereby achieving uniform mixing of the fertilizer. During the mixing process, if highly viscous fertilizer adheres to the mixing tank... As fertilizer accumulates on the inner bottom of mixing tank 1, the cleaning and anti-clogging component begins to function. The rotation of the rotating rod 3 synchronously drives the scraper 6 to rotate via the connecting rod 5 at the bottom. Since the contour of the scraper 6 matches the contour of the inner bottom of mixing tank 1, the scraper 6 can continuously scrape the bottom of mixing tank 1 while rotating. The triangular plate 8 fixed on the front side of the scraper 6 facing the direction of rotation will actively scrape up the adhering fertilizer. The scraped fertilizer is then guided into the groove 7 behind the triangular plate 8. Because the inner wall surface of the groove 7 is coated with... With an anti-sticking material layer, fertilizer does not easily stagnate in the groove 7 and will smoothly slide towards the center discharge port at the bottom of the mixing tank 1. At the same time, the fixing rod 9, coaxially connected to the center of the bottom of the connecting rod 5, also rotates synchronously. The fixing rod 9 continuously agitates and clears the fertilizer about to enter the discharge port, effectively breaking the arching phenomenon that the material will form and preventing blockage of the discharge port. Through the synergistic action of the scraper 6, the triangular plate 8, the groove 7, and the fixing rod 9, this utility model solves the problem of bottom blockage caused by the high viscosity of fertilizer in the prior art. To address the issues of material sticking and poor discharge, when the mixed fertilizer needs to be discharged, the operator must first loosen and remove the threaded sleeve 14 at one end of the threaded locking post 13 by turning it counterclockwise. Then, by pulling the pull ring 15 at the other end of the locking post 13, the locking post 13 can be completely pulled out from the through holes of the two fixing blocks 12 and the through hole of the baffle 11. After the locking post 13 is pulled out, the locking of the baffle 11 is released, and the baffle 11 pivots downward around the hinge 10 under the action of gravity, allowing the fertilizer inside the mixing tank 1 to be discharged smoothly from the bottom.
