Description

Technical Field

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

[0002] In the rose cultivation industry, fertilizer quality plays a crucial role in the growth, yield, and quality of roses. High-quality rose fertilizer requires a uniform mixture of various components to meet the nutrient needs of roses at different growth stages. However, current mixing equipment used in rose fertilizer processing has many problems.

[0003] Traditional fertilizer mixing methods rely heavily on manual stirring, which is not only labor-intensive and inefficient, but also makes it difficult to ensure the uniform mixing of various fertilizer components, easily leading to inconsistent fertilizer quality and affecting the growth of roses. With the development of agricultural mechanization, some mechanized mixing devices have begun to be applied in the field of fertilizer processing.

[0004] For example, patent document CN201620471924.4 discloses a "fertilizer mixing device" that mixes fertilizer using a stirring shaft and stirring blades. However, this device has a relatively simple stirring structure, only capable of basic stirring. When dealing with the various textures and particle sizes that may be present in rose fertilizer, it cannot achieve comprehensive, multi-layered, and efficient mixing, easily leading to mixing dead zones and poor mixing results. Furthermore, the device's discharge design is also inadequate. The discharge port structure is simple and lacks effective auxiliary discharge measures, easily causing poor fertilizer discharge, slow discharge speed, and significant fertilizer residue inside the device after discharge, wasting raw materials and increasing cleaning difficulty and cost. In summary, existing mixing devices for rose fertilizer processing have significant deficiencies in terms of mixing uniformity, stirring efficiency, smooth discharge, and reducing residue. Utility Model Content

[0010] Preferably, the first stirring component includes a pair of stirring rods and a first stirring blade and a second stirring blade disposed at both ends of the pair of stirring rods; the second stirring component includes a pair of stirring rods and a third stirring blade disposed at the bottom of the pair of stirring rods respectively.

[0011] Preferably, the second mounting rod is further provided with a support rod at one end away from the stirring main shaft; the support rod is provided with a fourth stirring blade that contacts the inner wall of the mixing chamber.

[0014] Preferably, the cylinder extends the piston rod, causing the discharge baffle to rotate based on the second connecting rod to open the discharge port; the cylinder retracts the piston rod, causing the discharge baffle to rotate based on the second connecting rod to close the discharge port.

[0015] Preferably, the discharge port is equipped with a guide plate.

[0016] The mixing device for processing rose fertilizer provided by this utility model has the following beneficial effects:

[0017] In this invention, the mixing device for processing rose fertilizer uses a first mixing section and a second mixing section working together to mix the fertilizer from different angles and areas, forming a three-dimensional mixing process. This effectively solves the problem of uneven fertilizer mixing, ensuring that all components of the rose fertilizer are fully integrated and improving fertilizer quality. The scraper at the bottom of the second mixing section, positioned in opposite directions, simultaneously cleans the bottom of the mixing chamber during the mixing process, preventing fertilizer residue from accumulating and ensuring that there are no dead corners in each mixing, thus reducing raw material waste. The dual mixing structure accelerates the flow rate of materials, significantly shortening the mixing time. Compared with the traditional single mixing method, it significantly improves mixing efficiency and meets the needs of mass production. The arc-shaped discharge port, combined with an automatic opening and closing mechanism, enables rapid and smooth discharge of fertilizer, further improving overall operating efficiency while reducing manual intervention and labor intensity.

[0032] Example 1

[0033] Please see Figure 1 This utility model provides a mixing device for processing rose fertilizer, including a frame 100, a mixing chamber, and a stirring mechanism; the mixing chamber 200 is disposed on the frame 100 and has a mixing cavity 210 inside; the bottom of the mixing cavity 210 is provided with an arc-shaped discharge port 211, which is opened or closed by a discharge baffle 212; the top of the mixing chamber 200 is provided with an opening for fertilizer to enter the mixing cavity 210.

[0034] Please see Figure 1 , Figure 3 and Figure 4 The mixing mechanism includes a mixing spindle 320 disposed within the mixing chamber 210 via a rotary seat 310, and a first mixing part disposed on the mixing spindle 320. The mixing spindle 320 is driven by a motor 110 disposed on the frame 100, causing the mixing spindle 320 to drive the first mixing part to rotate within the mixing chamber 210, thereby mixing the fertilizer within the mixing chamber 210. The top of the mixing chamber 300 has an opening for the fertilizer to enter the mixing chamber 310.

[0035] In use, different types of fertilizers are added through the opening of the mixing chamber 210, and then the motor 110 is started to drive the stirring shaft 320. The stirring shaft 320 drives the first stirring unit to rotate within the mixing chamber 210, thoroughly mixing the various types of fertilizers. The structure of the first stirring unit effectively improves mixing efficiency and ensures uniform fertilizer mixing. Furthermore, the outlet 211 facilitates the smooth discharge of the mixed fertilizer, while the outlet baffle 212 allows for flexible control of the opening and closing of the outlet 211 as needed, enhancing the practicality and flexibility of the device.

[0036] Further, please see Figure 1 The motor 110 drives the stirring spindle 320 through a transmission mechanism mounted on the frame 100. A driven gear 111 is fixedly provided at the bottom of the stirring spindle 320. The transmission mechanism includes a transmission base 121 and a transmission shaft 122 that can rotate based on the transmission base 121. The transmission shaft 122 is connected to the motor 110 via a pulley. A bevel gear 123 is provided at the other end of the transmission base 121 and is connected to the driven gear 111.

[0037] When in use, the motor 110 is started, and the motor 110 drives the transmission shaft 122 through belt drive, thereby causing the bevel gear 123 on the transmission shaft 122 to drive the driven gear 111 to realize the rotation of the stirring main shaft 320.

[0038] Furthermore, a protective cover can be installed on the frame 100 surrounding the transmission mechanism to prevent external objects from accidentally contacting the transmission gears and belts, ensuring operational safety. Simultaneously, the design of the protective cover should facilitate daily maintenance and inspection, ensuring the transmission mechanism is always in good working condition. In addition, the transmission gears and belts can be inspected and lubricated regularly to reduce wear, extend service life, and ensure the stable operation of the entire mixing unit.

[0039] Because fertilizer has a high density and requires a large mixing force, this transmission structure effectively transmits the power of the motor 110, ensuring that the mixing shaft 320 has sufficient torque for mixing. Furthermore, the bevel gear 123 transmission method makes power transmission smoother, reducing vibration and noise during the mixing process and improving the stability and durability of the equipment.

[0040] Further, please see Figure 4 The stirring spindle 320 is further provided with a second stirring part; the second stirring part is connected to the stirring spindle 320 in a transmission connection to drive the second stirring part to rotate.

[0041] Since fertilizers may be in a relatively compact state, it may be difficult to mix them or the mixing effect may be poor if only the first mixing part is used. Therefore, by setting up a second mixing part to assist the first mixing part in the mixing operation, the mixing effect can be significantly improved.

[0042] The second stirring section and the first stirring section are reasonably distributed on the stirring main shaft 320, which can ensure that different types of fertilizers can be fully stirred during the stirring process, avoiding the problem of uneven fertilizer mixing.

[0043] During mixing, the second mixing section operates in conjunction with the first mixing section. Therefore, the fertilizer, after being mixed by the first section, is not yet in a clumped or compacted state. The second mixing section helps to address the problem of compacted fertilizer being difficult to mix, making the entire mixing process more efficient and smooth. Driven by the mixing shaft 320, the first and second mixing sections work together to complete the fertilizer mixing operation, providing strong support for subsequent fertilization.

[0044] Further, please see Figure 3The second stirring part includes a third mounting rod 361 and a third stirring element 362 that can rotate based on the third mounting rod 361; the bottom of the third stirring element 362 is provided with a first scraper 363 and a second scraper 364, and the scraping directions of the first scraper 363 and the second scraper 364 are arranged in opposite directions.

[0045] During use, as the third stirring component 362 rotates, the first scraper 363 and the second scraper 364 can scrape the bottom wall of the mixing chamber 200 respectively, preventing fertilizer from adhering to the bottom wall of the mixing chamber 200, reducing fertilizer waste, and ensuring the cleanliness of the mixing chamber 200.

[0046] Furthermore, the opposite scraping directions of the first scraper 363 and the second scraper 364 further enhance the mixing effect on the fertilizer, resulting in a finer and more uniform fertilizer. This design not only improves mixing efficiency but also ensures the quality of fertilizer mixing, providing a more reliable fertilizer supply for agricultural production.

[0047] After mixing, the mixed fertilizer can be easily discharged by controlling the opening and closing of the discharge port 211 and the discharge baffle 212 for subsequent fertilization operations. The entire device has a simple structure, is easy to operate, and is highly practical, bringing great convenience to agricultural production.

[0048] Further, please see Figure 3 and Figure 4 The first stirring section includes a first sub-stirring section 340 and a second sub-stirring section 350 arranged at a preset angle; the first sub-stirring section 340 includes a first mounting rod 341 and a first stirring element disposed on the first mounting rod 341, the first stirring element including a pair of stirring rods 342 and a first stirring blade 343 and a second stirring blade 344 at both ends; the second sub-stirring section 350 includes a second mounting rod 351 and a second stirring element disposed on the second mounting rod 351, the second stirring element including a pair of stirring rods 342 and a third stirring blade 352 at the bottom; and the second mounting rod 351 is provided with a support rod 353 at one end away from the stirring main shaft 320, and a fourth stirring blade 354 is provided on the support rod 353 that contacts the inner wall of the mixing chamber 200.

[0049] In this embodiment, by setting at least two stirring sections to stir the fertilizer, the fertilizer can be mixed more thoroughly, improving stirring efficiency. The first sub-stirring section 340 and the second sub-stirring section 350 are arranged at a predetermined angle interval. This design allows for a wider stirring range and more uniform flow of fertilizer within the mixing chamber 200, avoiding localized excessively high or low fertilizer concentrations and further improving the uniformity of fertilizer mixing. Simultaneously, the first and second stirring components are respectively mounted on the first mounting rod 341 and the second mounting rod 351, allowing for independent rotation without interference, enhancing the flexibility and stability of the stirring process. This structural design not only improves the mixing quality of the fertilizer but also ensures the durability and reliability of the stirring device, providing a superior fertilizer mixing solution for agricultural production.

[0050] Further, please see Figure 4 The first stirring component includes a pair of stirring rods 342 and a first stirring plate 343 and a second stirring plate 344 disposed at both ends of the pair of stirring rods 342. An opening for fertilizer passage is formed between the first and second stirring components. This allows the fertilizer to be mixed more finely not only by the stirring action of the stirring rods 342 during the stirring process, but also through the opening between the first stirring plate 343 and the second stirring plate 344. The arrangement of the first stirring plate 343 and the second stirring plate 344 increases the contact area with the fertilizer during stirring, resulting in more frequent collisions and friction between fertilizer particles, thereby improving the uniformity of mixing. At the same time, the presence of the opening allows the fertilizer to flow freely during the stirring process, reducing dead zones and further ensuring thorough mixing of the fertilizer. In addition, the synergistic effect of the stirring rods 342, the first stirring plate 343, and the second stirring plate 344 not only enhances the stirring effect but also improves the durability and stability of the stirring component, providing a strong guarantee for long-term continuous stirring of fertilizer.

[0051] The second mixing component includes a pair of mixing rods 342 and third mixing blades 352 respectively disposed at the bottom of the pair of mixing rods 342. The third mixing blades 352 mainly scrape and stir the bottom, ensuring that the fertilizer accumulated at the bottom of the container is effectively mixed during the mixing process. This avoids the problem of insufficient bottom mixing common in traditional mixing methods, making the entire mixing process more uniform and efficient. The third mixing blades 352 can contact the bottom of the container without damaging it, allowing the entire mixing component to remain stable during the mixing process, further improving mixing efficiency and mixing uniformity.

[0052] Furthermore, a support rod 353 is provided at the end of the second mounting rod 351 away from the mixing shaft 320; the support rod 353 is provided with a fourth stirring blade 354 that contacts the inner wall of the mixing chamber 200. The fourth stirring blade 354 mainly scrapes and stirs the side wall, ensuring that the fertilizer adhering to the side wall of the mixing chamber 200 can also be effectively mixed during the mixing process. This avoids the problem of fertilizer adhering to the side wall in traditional mixing methods, which leads to uneven mixing or difficulty in removing fertilizer, making the entire mixing process more comprehensive and efficient.

[0053] The fourth stirring plate 354 can be in close contact with the side wall of the mixing chamber 200, and with the support rod 353, the fourth stirring plate 354 can stir more flexibly, further improving the stirring efficiency and mixing uniformity.

[0054] Furthermore, an installation sleeve 330 is fixedly provided on the top of the stirring spindle 320; the first installation rod 341, the second installation rod 351 and the third installation rod 361 are arranged at a preset angle on the installation sleeve 330.

[0055] By installing the sleeve 330, a first transmission gear can be installed on the top of the stirring shaft 320, and a second transmission gear connected to the first transmission gear is installed on the top of the third stirring component 362. This allows the stirring shaft 320 to drive the second stirring component to stir simultaneously when it rotates, enabling the two stirring components to rotate synchronously and improving stirring efficiency.

[0056] Meanwhile, the design of the mounting sleeve 330 makes the installation and disassembly of the mixing device more convenient, and facilitates the maintenance and replacement of the mixing components.

[0057] Furthermore, the first mounting rod 341, the second mounting rod 351, and the third mounting rod 361 are spaced at a predetermined angle on the mounting sleeve 330. This arrangement allows for a wider mixing range and smoother flow of fertilizer within the mixing chamber 200, further improving the uniformity of fertilizer mixing. This structural design not only optimizes the mixing effect but also enhances the practicality and durability of the mixing device, providing a more efficient and reliable solution for fertilizer mixing in agricultural production.

[0058] Further, please see Figure 2 The discharge baffle 212 opens or closes the discharge port 211 via an automatic opening and closing mechanism; the automatic opening and closing mechanism is mounted on the frame 100 and is hinged to the discharge baffle 212 via a first connecting rod 421 located at the end of the piston rod 411 of the cylinder 410; the automatic opening and closing mechanism has a hinge part 430 on the frame 100, and the hinge part 430 is hinged to the discharge baffle 212 via a second connecting rod 431.

[0059] The cylinder 410 extends the piston rod 411, causing the discharge baffle 212 to rotate based on the second connecting rod, thereby opening the discharge port 211; the cylinder 410 retracts the piston rod 411, causing the discharge baffle 212 to rotate based on the second connecting rod, thereby closing the discharge port 211.

[0060] The advantage of this design is that it allows for precise control of the discharge port 211, effectively preventing fertilizer leakage and waste. After the fertilizer is mixed, the extension of the piston rod 411 of the cylinder 410 quickly opens the discharge port 211, allowing the uniformly mixed fertilizer to be discharged smoothly. When it is necessary to stop discharging, the retraction of the piston rod 411 of the cylinder 410 promptly closes the discharge port 211, ensuring the device's airtightness. Furthermore, this automatic opening and closing mechanism design significantly reduces the workload of operators and improves work efficiency.

[0061] Furthermore, the discharge port 211 is provided with a guide plate 213, which can guide the discharged fertilizer to a designated position, avoiding the scattering and accumulation of fertilizer, and making the collection and utilization of fertilizer more convenient.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
