Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, specifically to a compound fertilizer production mixing machine. Background Technology

[0002] In the development of modern agriculture, compound fertilizers, due to their comprehensive nutrition and long-lasting effects, have become a key agricultural input for improving crop yield and quality. The mixing process, as the core step in compound fertilizer production, directly affects the uniformity of fertilizer nutrients and its application effectiveness. A mixing machine is a commonly used mixing device.

[0003] Utility model patent application number CN202321145348.0 discloses a mixing preparation tank for compound fertilizer production. This mixing preparation tank includes a base, with a tank body fixedly connected inside the base. A motor is fixedly connected to the top center of the tank body, and a first stirring rod is fixedly connected to the output end of the motor. A first gear is fixedly connected to the upper outer side of the first stirring rod, and a support frame is fixedly connected to the bottom end of the first stirring rod. In this utility model, the coordinated use of a second stirring rod, a second gear, a scraper, and a water inlet pipe allows for convenient cleaning of the tank interior after mixing, thereby reducing labor intensity and increasing cleaning efficiency.

[0004] Although the mixing tank used in compound fertilizer production facilitates cleaning of its interior, the device still presents the following problems in actual use: The device uses a scraper to clean the inner wall of the tank, and the scraper is externally fixed to the second stirring rod. However, due to the dual constraints of the internal spatial layout of the mixing drum and the scraper's fixed installation method, disassembling the scraper requires simultaneous handling of multiple related components, and the operating space is extremely limited, significantly increasing the difficulty of disassembly. This situation makes it impossible to replace and maintain the scraper in a timely and convenient manner when it shows signs of wear, thus affecting the subsequent use of the equipment. Therefore, we propose a compound fertilizer production mixing machine. Utility Model Content

[0005] The purpose of this utility model is to provide a compound fertilizer production mixing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0021] Preferably, a connecting rod is fixed to one side wall of the slider, the end of the connecting rod passes through a slot and is fixedly connected to the dial head by bolts, and a spring is sleeved on the outside of the connecting rod;

[0022] Preferably, the spring is in an extended state, with its two ends abutting against the slider and the inner wall of the slide cavity, respectively.

[0023] Of these three settings, the slotted setting provides ample operating space for the dial head. Users can easily control the slider to slide by turning the dial head, thereby separating the card head from the card slot of the scraper, making the scraper disassembly operation more convenient and efficient.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. Through the set stirring components, the motor drives the rotating shaft and stirring blades to rotate, which can fully stir the compound fertilizer raw materials; the stirring blades and the rotating shaft are coaxially keyed, ensuring stable power transmission, ensuring stirring efficiency, and achieving uniform mixing of raw materials;

[0026] 2. When the scraper needs to be disassembled, the slider is moved within the sliding cavity by manually operating the dial, easily controlling the engagement and disengagement of the clamp and slot. This design eliminates the need for complex tools and cumbersome operations during scraper disassembly, reducing maintenance difficulty and saving maintenance time and costs. Simultaneously, as the slider slides within the sliding cavity, the clamp and slot on the scraper engage under the pressure of the spring. This engagement method is simple in structure and ensures that the scraper stably presses against the inner wall of the mixing drum, effectively cleaning residual material from the drum wall.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This embodiment provides a technical solution:

[0038] Please see Figure 1 As shown, a compound fertilizer production mixing machine includes a mixing drum 1 with an open top for holding compound fertilizer production raw materials for mixing; a cover 2 with an open bottom and detachably connected to the mixing drum 1; and a motor 20 installed on the top of the cover 2.

[0039] With the above setup, the cover 2 is bolted to the mixing drum 1, making disassembly convenient and facilitating equipment inspection and maintenance.

[0040] In this embodiment, a discharge port 10 is installed at the bottom of the mixing drum 1, and a plug is threaded to the bottom end of the discharge port 10. The bottom discharge port 10 is connected to the plug by thread, which ensures sealing while enabling convenient control of discharge.

[0041] In this embodiment, the cover 2 is bolted to the mixing drum 1. The bottom of the cover 2 has a feed inlet 21, with a threaded sealing cap connected to the feed inlet 21. The feed inlet 21, with its threaded sealing cap, can be opened flexibly during feeding and effectively prevents material leakage and the entry of external impurities when not in use, ensuring the purity of the raw materials. The bolted fastening method allows the cover 2 to be easily disassembled, facilitating the removal of the mixing assembly 3 from the mixing drum 1.

[0042] Please see Figures 2-5As shown, the stirring assembly 3 is installed inside the opening of the stirring drum 1 and is used to stir the raw materials for compound fertilizer production for mixing. The stirring assembly 3 includes a rotating shaft 30 coaxially keyed to the output shaft of the motor 20, and multiple stirring blades 31 coaxially keyed to the outer wall of the rotating shaft 30. Two support rods 32 are fixed on the upper and lower sides of the outer wall of the rotating shaft 30, and a sliding cavity 321 is provided at the end of the support rod 32. A slider 34 is slidably installed in the sliding cavity 321, and a spring 37 for pressing against the slider 34 is also provided in the sliding cavity 321. A clip is fixed to the end face of the slider 34 away from the connecting rod 36. The head 35; a connecting frame 33 is fixed at the end of the support rod 32, and an installation groove 330 is provided at the connecting frame 33. Limiting strips 331 are fixed on both sides of the installation groove 330; the end of the clamping head 35 is inserted into the installation groove 330; a scraper 39 is provided between two adjacent connecting frames 33, and the end face of the scraper 39 away from the rotating shaft 30 is pressed against the inner wall of the mixing cylinder 1; limiting grooves 390 that slide with the limiting strips 331 are provided on both sides of the scraper 39; two clamping grooves 391 are provided on the other end face of the scraper 39, and the clamping head 35 is engaged with the clamping grooves 391.

[0043] With the above settings, the slider 34 in the sliding cavity 321 at the end of the support rod 32 can be kept stable under the action of the spring 37, so that the clamp 35 can be reliably engaged with the groove 391 of the scraper 39. While ensuring the stability of stirring, it also provides operating space for the disassembly and replacement of the scraper 39.

[0044] Please see Figure 3 and Figure 4 As shown, in this embodiment, the connecting frame 33 has a U-shaped cross-section and is tightly welded to the support rod 32. The U-shaped design facilitates the installation of the scraper 39, while the tight welding ensures the connection stability between the connecting frame 33 and the support rod 32.

[0045] In this embodiment, the slider 34 and the clamp 35 are integrally molded structures, and both the slider 34 and the clamp 35 are made of stainless steel. The integrally molded slider 34 and the clamp 35 have the advantages of high structural strength and good wear resistance, and can withstand the complex stress during the stirring process.

[0046] Please see Figure 3 and Figure 4 As shown, in this embodiment, a through groove 320 is provided on one side of the sliding cavity 321, and a dial 38 is provided in the through groove 320. The through groove 320 provides sufficient operating space for maneuvering the dial 38.

[0047] Please see Figure 4As shown, in this embodiment, a connecting rod 36 is fixed to one side wall of the slider 34. The end of the connecting rod 36 passes through the slot 320 and is fixedly connected to the dial head 38 by bolts. A spring 37 is sleeved on the outside of the connecting rod 36. Because the connecting rod 36 is connected to the slider 34, the operator can manually move the dial head 38 to easily control the slider 34 to slide, thereby separating the clamp head 35 from the slot 391 of the scraper 39, making the disassembly of the scraper 39 more convenient and efficient.

[0048] In this embodiment, the spring 37 is in an extended state, with its two ends abutting against the slider 34 and the inner wall of the sliding cavity 321, respectively. The spring 37 provides a continuous and stable locking force to the latch 35, ensuring that the latch 35 is stably engaged with the latch groove 391.

[0049] It is worth noting that the motor 20 involved in this embodiment is a conventional technology and will not be described in detail here.

[0050] In the compound fertilizer production process, the operator first loads the raw materials into the mixing drum 1 through the bottom feed inlet 21, and then fixes the cover 2 to the top of the mixing drum 1 with bolts. Then the operator turns on the power to the motor 20, and the motor 20 starts to work. The output shaft of the motor 20 drives the rotating shaft 30 to rotate, and the rotating shaft 30 drives the mixing blades 31 to mix the raw materials through a coaxial key connection.

[0051] When it is necessary to disassemble the scraper 39, the user first removes the connecting bolts between the cover 2 and the mixing drum 1. Then, the user lifts the cover 2 upwards, which causes the mixing assembly 3 to detach from the mixing drum. The user then manually moves the dial 38 in the slot 320. The dial 38 drives the slider 34 to slide in the sliding cavity 321 through the connecting rod 36. The spring 37 is then compressed, and the locking head 35 is separated from the locking groove 391, thus releasing the locking. Finally, the scraper 39 is pulled upwards along the direction of the limiting strip 331, so that its limiting groove 390 is disengaged from the limiting strip 331, thus completing the disassembly of the scraper 39.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
