Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer mixers, specifically a vertical mixer for compound fertilizers. Background Technology

[0002] In the production process of compound fertilizer, it is crucial to uniformly mix fertilizers of different components in order to ensure the quality and efficacy of the fertilizer. This is because compound fertilizers are composed of a variety of nutrients (such as nitrogen, phosphorus, and potassium), and different crops have different requirements for the proportion of these nutrients. If the fertilizer is not mixed evenly, the crops in the fertilization area will not be able to obtain nutrients in an even manner, which will affect the growth, development and yield of the crops. Therefore, a fertilizer mixer is needed to mix the fertilizer.

[0003] Traditional mixing mechanisms typically use a single stirring rod to agitate the fertilizer inside the tank. A single stirring rod cannot adequately handle vertical mixing, causing fertilizer to tend to accumulate at the bottom and become difficult to mix thoroughly with the fertilizer at the top. Furthermore, fertilizer tends to adhere to the inner wall of the mixing tank. Over time, this residual fertilizer will mix into the new fertilizer, affecting the purity and quality of subsequent fertilizers. Utility Model Content

[0004] The purpose of this invention is to provide a vertical mixer for compound fertilizers, which solves the problem that traditional mixing mechanisms typically use a single mixing rod to mix the fertilizer inside the tank. A single mixing rod cannot adequately handle vertical mixing, leading to fertilizer accumulation at the bottom, making it difficult to mix thoroughly with the fertilizer at the top. Furthermore, fertilizer tends to adhere to the inner wall of the mixing tank, and over time, this residual fertilizer will mix into the new fertilizer, affecting the purity and quality of subsequent fertilizers.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a vertical mixer for compound fertilizer, comprising a mounting platform, several support rods fixedly mounted on the lower surface of the mounting platform, a mixing tank fixedly mounted inside the mounting platform, a cover plate fixedly mounted on the upper surface of the mixing tank, a feed pipe fixedly mounted on the upper surface of the cover plate, the feed pipe being connected to the interior of the mixing tank, a discharge pipe fixedly mounted on the lower surface of the mixing tank, a valve installed inside the discharge pipe, and a mixing mechanism mounted on the outer surface of the cover plate, wherein the mixing end and the scraping end of the mixing mechanism are both located inside the mixing tank.

[0007] Furthermore, the stirring mechanism includes a motor, which is fixedly mounted on the upper surface of the cover plate. A rotating rod is fixedly mounted on the output end of the motor, extending into the interior of the stirring tank. Several sets of stirring paddles are fixedly mounted on the circumferential side of the rotating rod.

[0008] Furthermore, an extension rod is fixedly installed at one end of the rotating rod, and a spiral blade is fixedly installed on the outer surface of the extension rod.

[0009] Furthermore, each of the two stirring paddles has an installation groove at one end, and a positioning block is inserted into the inside of each installation groove. The positioning block is fixedly installed to the stirring paddle by locking bolts, and a fixing rod is fixedly installed at one end of each positioning block.

[0010] Furthermore, a scraper mounting seat is fixedly installed at one end of each of the two fixing rods.

[0011] Furthermore, a scraper is fixedly installed on one side of the scraper mounting base, and the scraper abuts against the inner wall of the mixing tank.

[0012] This utility model has the following beneficial effects:

[0013] (1) This utility model starts with a motor, which drives the rotating rod to rotate. Several sets of stirring paddles on the circumference of the rotating rod rotate with the rotation of the rotating rod, stirring the compound fertilizer in the mixing tank. The rotation of the stirring paddles makes the fertilizer fully mixed in the mixing tank. Fertilizer particles of different components come into contact with each other and turn over, achieving the purpose of uniform mixing. At the same time, the extension rod at one end of the rotating rod and the spiral blade on the outer surface of the extension rod also rotate. The spiral blade helps to push the fertilizer at the bottom upward, preventing the fertilizer from accumulating at the bottom, so that the fertilizer can also be fully stirred in the vertical direction of the mixing tank. Since the scraper is in contact with the inner wall of the mixing tank, when the stirring paddle rotates, the scraper will scrape off the fertilizer attached to the inner wall of the mixing tank, which improves the uniformity of mixing and avoids fertilizer residue on the tank wall. Residual fertilizer will be mixed into the new fertilizer during the next mixing, resulting in uneven fertilizer composition or impurities.

[0014] (2) When the scraper needs to be replaced, the cover plate is opened and then taken out of the inside of the mixing tank. The two locking bolts are unscrewed from the inside of the positioning block and the mixing paddle, and the positioning block can be taken out. The scraper can then be disassembled and replaced. The new scraper can then be installed. This makes it convenient to replace or repair the scraper and reduces maintenance costs.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-4 As shown, this utility model is a vertical mixer for compound fertilizer, including a mounting platform 1. Several support rods 2 are fixedly installed on the lower surface of the mounting platform 1. A mixing tank 3 is fixedly installed inside the mounting platform 1. A cover plate 4 is fixedly installed on the upper surface of the mixing tank 3. A feed pipe 5 is fixedly installed on the upper surface of the cover plate 4. The feed pipe 5 is connected to the inside of the mixing tank 3. A discharge pipe 6 is fixedly installed on the lower surface of the mixing tank 3. A valve 7 is installed inside the discharge pipe 6. A mixing mechanism 8 is installed on the outer surface of the cover plate 4. The mixing end and the scraping end of the mixing mechanism 8 are both located inside the mixing tank 3.

[0025] The stirring mechanism 8 includes a motor 801, which is fixedly installed on the upper surface of the cover plate 4. A rotating rod 802 is fixedly installed at the output end of the motor 801. The rotating rod 802 extends into the interior of the stirring tank 3. Several sets of stirring paddles 803 are fixedly installed on the circumferential side of the rotating rod 802.

[0026] An extension rod 804 is fixedly installed at one end of the rotating rod 802, and a spiral blade 805 is fixedly installed on the outer surface of the extension rod 804.

[0027] One end of each of the two agitators 803 is provided with an installation groove 806, and a positioning block 807 is inserted into the installation groove 806. The positioning block 807 is fixedly installed to the agitator 803 by locking bolts 808, and a fixing rod 809 is fixedly installed at one end of the positioning block 807.

[0028] Scraper mounting bases 810 are fixedly installed at one end of the two fixing rods 809;

[0029] A scraper 811 is fixedly installed on one side of the scraper mounting base 810, and the scraper 811 abuts against the inner wall of the mixing tank 3.

[0030] The motor 801 starts, driving the rotating rod 802 to rotate. Several sets of stirring paddles 803 on the circumference of the rotating rod 802 rotate along with it, stirring the compound fertilizer in the mixing tank 3. The rotation of the stirring paddles 803 ensures thorough mixing of the fertilizer within the mixing tank 3, with fertilizer particles of different components contacting and agitating each other to achieve uniform mixing. Simultaneously, the extension rod 804 at one end of the rotating rod 802 and the spiral blades 805 on the outer surface of the extension rod 804 also rotate. 05 helps to push the fertilizer at the bottom upwards, preventing it from accumulating at the bottom and ensuring that the fertilizer is fully mixed in the vertical direction of the mixing tank 3. Since the scraper 811 is in contact with the inner wall of the mixing tank 3, when the mixing paddle 803 rotates, the scraper 811 will scrape off the fertilizer adhering to the inner wall of the mixing tank 3, thereby improving the uniformity of mixing and preventing fertilizer residue on the tank wall. Residual fertilizer will be mixed into the new fertilizer during the next mixing, resulting in uneven fertilizer composition or impurities.

[0031] When in use, the raw materials of compound fertilizer first enter the mixing tank 3 through the feed pipe 5. The feed pipe 5 is connected to the inside of the mixing tank 3, so that the material can smoothly enter the mixing area.

[0032] The motor 801 starts, driving the rotating rod 802 to rotate. Several sets of stirring paddles 803 on the circumference of the rotating rod 802 rotate along with it, stirring the compound fertilizer in the mixing tank 3. The rotation of the stirring paddles 803 ensures thorough mixing of the fertilizer within the mixing tank 3, with fertilizer particles of different components contacting and agitating each other to achieve uniform mixing. Simultaneously, the extension rod 804 at one end of the rotating rod 802 and the spiral blades 805 on the outer surface of the extension rod 804 also rotate. 05 helps to push the fertilizer at the bottom upwards, preventing it from accumulating at the bottom and ensuring that the fertilizer is fully mixed in the vertical direction of the mixing tank 3. Since the scraper 811 is in contact with the inner wall of the mixing tank 3, when the mixing paddle 803 rotates, the scraper 811 will scrape off the fertilizer adhering to the inner wall of the mixing tank 3, thereby improving the uniformity of mixing and preventing fertilizer residue on the tank wall. Residual fertilizer will be mixed into the new fertilizer during the next mixing, resulting in uneven fertilizer composition or impurities.

[0033] After mixing is complete, open valve 7 inside discharge pipe 6, and the mixed compound fertilizer is discharged from mixing tank 3 through discharge pipe 6;

[0034] When the scraper 811 needs to be replaced, the cover plate 4 is opened and then taken out of the mixing tank 3. The two locking bolts 808 are unscrewed from the inside of the positioning block 807 and the mixing paddle 803, so that the positioning block 807 can be taken out, and the scraper 811 can be disassembled and replaced. The new one can then be installed. This makes replacement or repair convenient and reduces maintenance costs.
