Description

Technical Field

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

[0002] In agriculture, blended fertilizers have become an important means of improving crop yield and quality because they can be precisely formulated according to the nutritional needs of different crops and soil fertility conditions. However, traditional blended fertilizer production processes suffer from numerous problems in the mixing and transportation stages, severely impacting production efficiency and fertilizer quality.

[0003] Existing patent CN220844320U discloses a blended fertilizer conveying structure, including multiple sets of first support legs, multiple sets of side support plates, a conveyor belt, and partitions. The side support plates are located on the top surface of the first support legs and are fixedly connected to them. The conveyor belt is located between two side support plates and is rotatably connected to them. The top surface of the conveyor belt has a linear array of partitions, which are fixedly connected to the conveyor belt. A conveying guide device is provided on the top surface of the first support legs. The conveying guide device includes a conveying plate for receiving materials and multiple sets of guide plates for guiding materials. The conveying plate is located between two side support plates and is fixedly connected to them. The guide plates are rotatably connected to the conveying plate. The device's guide plates interact to guide the flow of material on the surface of the conveyor plate, preventing fertilizer particles from flowing out randomly according to the size of the discharge port. This would cause the fertilizer to scatter in all directions, preventing it from falling into the designated area and increasing the workload of the operators.

[0004] However, during the mixing stage, the device only has a simple stirring function and cannot dehumidify and prevent moisture from entering the mixing silo, which causes the fertilizer particles to easily clump together during subsequent processing, affecting the quality of subsequent blended fertilizer processing.

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] In the attached diagram, all identical reference numerals refer to the same components.

[0018] like Figure 1-4As shown, this utility model provides a fertilizer blending and conveying device, including a mixing silo 1 and a conveying pipe 4. Support legs are installed at the four corners of the bottom of the mixing silo 1. A stirring assembly 2 is installed inside the mixing silo 1. A conveying assembly 3 is installed inside the conveying pipe 4. Four support plates are installed at the bottom of the conveying pipe 4. The top of the mixing silo 1 is open. A discharge pipe 5 is installed at the bottom of the mixing silo 1. The bottom wall of the mixing silo 1 is inclined towards the discharge pipe 5. A valve is installed at the connection between the discharge pipe 5 and the mixing silo 1. The other end of the discharge pipe 5 is connected to the conveying pipe 4.

[0019] In this embodiment, the stirring assembly 2 includes a motor 201, a sealing plate 202, a baffle 203, a sieve plate 204, a handle 205, a rotating rod 206, a stirring rod 207, a heating rod 208, and a scraper 209. The sieve plate 204 is installed between the sealing plate 202 and the baffle 203. The sealing plate 202 is circular, and the baffle 203 is semi-circular.

[0020] Furthermore, the sealing plate 202, the sieve plate 204, and the baffle 203 are all movably arranged inside the mixing bin 1. A motor 201 and a handle 205 are installed on one side of the sealing plate 202, with the handle 205 located below the motor 201.

[0021] Furthermore, a rotating rod 206 is installed on the rotating shaft of the motor 201. The other end of the rotating rod 206 is rotatably connected to the baffle 203 through a bearing seat. Multiple stirring rods 207 are installed on one side of the rotating rod 206, and multiple heating rods 208 are installed on the other side of the rotating rod 206.

[0022] Furthermore, a scraper 209 is connected to one end of the stirring rod 207 and the heating rod 208 respectively. One side of the outer wall of the scraper 209 is in contact with the sealing plate 202, and the other side of the outer wall is in contact with the baffle 203. The top wall size of the scraper 209 is adapted to the inner diameter of the sieve plate 204.

[0023] Specifically, the scraper 209 is cleverly designed. Its close fit with the sealing plate 202, baffle 203, and sieve plate 204 effectively scrapes off fertilizer adhering to various components during stirring and rotation, preventing fertilizer residue and clogging of the sieve plate 204, ensuring normal operation of the equipment, and reducing maintenance costs and downtime. The conveying assembly 3 uses motor 2 301 to drive gear 1 302 and gear 2 303 to rotate, which in turn drives the spiral blades 305 on the two drive rods 304 to rotate and convey fertilizer.

[0024] Example 2 In this embodiment, the conveying assembly 3 includes a second motor 301, a first gear 302, a second gear 303, a drive rod 304, a spiral blade 305, and a discharge pipe 306. The second motor 301 is mounted on one side of the conveying pipe 4 via a bracket, and the discharge pipe 306 is provided on the other side of the bottom of the conveying pipe 4.

[0025] Furthermore, two drive rods 304 are rotatably mounted inside the feed pipe 4, and each drive rod 304 is equipped with a spiral blade 305.

[0026] Furthermore, gear 1 302 and gear 2 303 are rotatably mounted on the side of the conveying pipe 4 near motor 2 301 via bearing housing. Gear 1 302 and gear 2 303 are meshed and connected. The rotating shaft of motor 2 301 is fixedly connected to gear 1 302.

[0027] Specifically, this double-helix conveying method can provide stable and continuous conveying power, ensuring that fertilizer is discharged evenly and stably from the discharge pipe 306, meeting the needs of large-scale production.

[0028] Working principle: Before use, connect the device to an external power source and control the device through the controller.

[0029] The fertilizer raw materials to be mixed are poured into the mixing hopper 1, which is open at the top. Motor 201 is started, and its rotating shaft drives the rotating rod 206 to rotate. Multiple stirring rods 207 on one side of the rotating rod 206 stir and mix the fertilizer raw materials in the mixing hopper 1, ensuring thorough and uniform mixing. Simultaneously, multiple heating rods 208 on the other side of the rotating rod 206 are activated to heat the fertilizer. Adjusting the temperature according to the fertilizer's characteristics can aid in the reaction of certain fertilizers or improve their physical properties. During the stirring and heating process, the scraper 209 connected to one end of the stirring rod 207 and the heating rod 208 rotates accordingly. One side of the outer wall of the scraper 209 is in contact with the sealing plate 202, and the other side of the outer wall is in contact with the baffle 203. The top wall size of the scraper 209 is matched with the inner diameter of the sieve plate 204. In this way, the scraper 209 can scrape off the fertilizer adhering to the sealing plate 202, the baffle 203 and the sieve plate 204, avoiding fertilizer residue and clogging of the sieve plate 204. At the same time, the sieve plate 204 can perform preliminary screening of the mixed fertilizer and remove larger particle impurities.

[0030] Heating by heating rod 208 raises the temperature of the environment around the fertilizer, drying out the internal moisture. This effectively prevents moisture from invading and causing the fertilizer to clump together. Stirring keeps the fertilizer turning over during the drying process, ensuring that all granules are heated evenly and avoiding local overheating or insufficient drying.

[0031] Once the fertilizer is mixed evenly and reaches the desired state, open the valve at the connection between the discharge pipe 5 and the mixing silo 1. Since the bottom wall of the mixing silo 1 is inclined towards the discharge pipe 5, the fertilizer flows into the conveying pipe 4 along the inclined bottom wall through the discharge pipe 5 under the action of gravity.

[0032] When motor 2 (301) is started, its rotating shaft drives gear 1 (302) to rotate. Because gear 1 (302) and gear 2 (303) are meshed, gear 2 (303) also rotates. Gear 1 (302) and gear 2 (303) respectively drive two drive rods (304) to rotate. The spiral blades (305) on the outside of the drive rods (304) rotate accordingly. The spiral blades (305) push the fertilizer flowing from the discharge pipe (5) into the conveying pipe (4) forward. Finally, the fertilizer is discharged from the discharge pipe (306) on the other side of the bottom of the conveying pipe (4), completing the fertilizer conveying process.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0034] Furthermore, all content not described in detail in this specification is prior art known to those skilled in the art.
