Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, and in particular to a compound fertilizer raw material mixer. Background Technology

[0002] Compound fertilizer is a type of fertilizer containing at least two of the three nutrients: nitrogen, phosphorus, and potassium, in specified amounts. It contains a variety of nutrients, including nitrogen, phosphorus, and potassium, providing comprehensive nutrition to crops and meeting their nutritional needs at different growth stages, thus contributing to crop growth, development, and high and stable yields.

[0003] Chinese Patent CN221846921U discloses a compound fertilizer raw material mixing device, including a mixing box for mixing compound fertilizer raw materials. A collection cover is fixedly connected to the bottom of the mixing box. The mixing components include a first motor, which is fixedly installed on the bottom of a mounting plate. Mixing blades are symmetrically arranged on the surface of the rotating shaft, and connecting frames are arranged in a circumferential array on the surface of the rotating shaft. Scrapers are fixedly connected to the connecting frames. In this device, a second motor drives the rotating shaft and the arc-shaped blades to rotate, initially mixing the raw materials in the baffle. The mixed raw materials fall into the mixing box through a feeding chute. The first motor drives the rotating shaft and the mixing blades to rotate again, further mixing and stirring the raw materials in the mixing box to ensure thorough mixing. A booster pump sends water into the mixing box and sprays it out through spray holes to rinse the inner wall of the mixing box for future use. After cleaning, a heater is turned on to send hot air into the mixing box to dry the inner wall of the mixing box.

[0004] However, the above technical solution has the following shortcomings: the device first mixes the raw materials once, then pours the raw materials in the baffle, and then mixes the raw materials a second time to improve the mixing effect of the raw materials. However, this method is not only cumbersome to operate, but also the efficiency of the two mixing actions is relatively low, which reduces the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a compound fertilizer raw material mixer that can not only effectively mix compound fertilizer raw materials, improving processing efficiency and quality, but also reduce the workload and enhance the practicality of the device.

[0007] Preferably, two mounting rings are coaxially provided on both the rotating shaft and the rotating rod, and the mounting rings are rotatably connected to the housing and the connecting plate, respectively.

[0008] Preferably, the bottom of the box is set as an inclined surface, the scraper includes an inclined part and a vertical part, and the scraper and the box are slidably connected.

[0009] Preferably, a feeding funnel is provided on the box body, and the bottom of the feeding funnel penetrates through the connecting plate and extends into the interior of the box body.

[0010] Preferably, a water tank is provided on the mounting base, a water pump is connected to the water tank, a water inlet is provided on the connecting plate, a water supply pipe is connected between the water pump and the water inlet, and a first control valve is provided on the water supply pipe.

[0012] Preferably, a discharge pipe is provided on the housing, and a second control valve is provided on the discharge pipe.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This invention utilizes a stirring device that drives multiple sets of stirring blades, stirring rods, and scrapers to effectively mix the materials inside the box, including the corners and upper and lower layers. This improves the mixing efficiency and effectiveness of the raw materials. Simultaneously, a fixed plate assists in agitating the materials, enhancing their fluidity and further increasing mixing efficiency.

[0020] Example 1

[0021] like Figures 1-4 As shown in the figure, the compound fertilizer raw material mixer proposed in this embodiment includes a mounting base 1 and a stirring device; a box 2 is provided on the mounting base 1, and a connecting plate 3 is provided inside the box 2.

[0022] The stirring device includes a motor 4 mounted on a housing 2, a first gear 5 driven by the motor 4, a rotating shaft 6 rotatably mounted on the housing 2, a second gear 7 and a third gear 8 coaxially mounted on the rotating shaft 6, three rotating rods 9 arranged in a ring array and rotatably mounted on a connecting plate 3, a fourth gear 10 coaxially mounted on the rotating rods 9, multiple sets of stirring blades 11 linearly distributed on the rotating rods 9, a stirring rod 12 mounted at the bottom of the rotating rods 9, a scraper 13 mounted on the stirring rods 12, and a fixing plate 14 mounted on the scraper 13; the first gear 5 and the second gear 7 are meshed together, the third gear 8 and the three fourth gears 10 are meshed together, and the fixing plate 14 is provided with multiple holes 15.

[0023] In this embodiment, after various raw materials are added to the interior of the housing 2, the motor 4 is started to drive the first gear 5 to rotate. The first gear 5 and the second gear 7 mesh and transmit power, which in turn drives the rotating shaft 6 to drive the third gear 8 to rotate. The third gear 8 meshes and transmits power with three fourth gears 10 at the same time. The fourth gears 10 drive multiple sets of stirring blades 11 to rotate in the same direction in different areas inside the housing 2, so as to fully stir and mix the various raw materials, improve the mixing efficiency and effect of the raw materials. At the same time, the rotating shaft 6 drives the stirring rod 12 to rotate to stir the small amount of raw materials accumulated at the bottom of the housing 2. When the stirring rod 12 rotates, it also drives the scraper 13 to rotate. The scraper 13 drives the fixed plate 14 to rotate. The fixed plate 14 assists in stirring the raw materials, enhances the fluidity of the raw materials, and improves the mixing efficiency. In addition, the set leakage hole 15 can make the raw materials continuously squeezed and deformed during the stirring process, preventing the raw materials from accumulating and sticking on the fixed plate 14, ensuring the uniformity and continuity of the stirring, improving the ink mixing efficiency, and having good practicality.

[0024] Example 2

[0025] like Figure 2 and Figure 3 As shown in this embodiment, a compound fertilizer raw material mixer is proposed. Compared with the first embodiment, in this embodiment, two mounting rings 16 are coaxially arranged on both the rotating shaft 6 and the rotating rod 9. The mounting rings 16 are rotatably connected to the box body 2 and the connecting plate 3, respectively. The mounting rings 16 are used to install the rotating shaft 6 and the rotating rod 9 on the box body 2 and the connecting plate 3, respectively, to ensure the stability of the rotating shaft 6 and the rotating rod 9 when rotating. The bottom of the box body 2 is set as an inclined surface. The scraper 13 includes an inclined part and a vertical part. The scraper 13 is slidably connected to the box body 2. When the scraper 13 drives the fixed plate 14 to rotate, its inclined part and vertical part will slide with the vertical surface and inclined surface of the inner wall of the box body 2, so as to avoid the situation that the raw materials near the inner wall are poorly mixed during the mixing process. At the same time, when discharging the material, the scraper 13 can also prevent some material from adhering to the inner wall and being difficult to discharge.

[0026] Example 3

[0027] like Figure 1 and Figure 4 As shown in the figure, the compound fertilizer raw material mixer proposed in this embodiment, compared with the first embodiment, has a feeding funnel 17 on the box 2. The bottom of the feeding funnel 17 passes through the connecting plate 3 and extends into the interior of the box 2. A discharge pipe 25 is provided on the box 2, and a second control valve 26 is provided on the discharge pipe 25.

[0028] A water tank 18 is provided on the mounting base 1, and a water pump 19 is connected to the water tank 18. A water inlet 21 is provided on the connecting plate 3. A water supply pipe 20 is connected between the water pump 19 and the water inlet 21. A first control valve 22 is provided on the water supply pipe 20. A cavity 23 is provided inside the connecting plate 3. Multiple nozzles 24 are arranged in a ring array on the connecting plate 3. The nozzles 24 and the cavity 23 are connected.

[0029] In this embodiment, the raw materials prepared in a certain proportion can be added into the interior of the box 2 through the feeding funnel 17, and the discharge of the material is controlled by the discharge pipe 25 and the second control valve 26. After the material is discharged, the water pump 19 is started to transport the cleaning liquid in the water tank 18 into the cavity 23 of the connecting plate 3 through the water pipe 20. Finally, it is sprayed from multiple nozzles 24 at the same time to rinse the various structures and inner walls inside the box 2. The motor 4 can be started to assist in cleaning during rinsing, which facilitates the subsequent use of the box 2.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
