Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, specifically to an automatic batching and mixing device for compound fertilizer production. Background Technology

[0002] Compound fertilizers have advantages such as high nutrient content, few by-products and good physical properties. They play a very important role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. The production process of compound fertilizers is complex, and one step in the production process is to mix the raw materials evenly.

[0003] Utility model patent CN215086675U discloses a compound fertilizer mixing device. It increases the flexibility of the device through mixing and lifting components, and the auxiliary mixing spiral blades improve mixing efficiency. This enhances the overall working efficiency of the compound fertilizer mixing device. The use of electric valves and conveyor belts reduces labor waste and improves the usability of the device. However, the existing technology has the following shortcomings: First, it lacks a precise batching module. Manual weighing is a long-standing industry practice, but manual operation is inefficient and prone to errors, leading to insufficient precision in the compound fertilizer ratio, affecting product quality and fertilizer efficacy stability. Second, the transmission structure of the mixing equipment directly drives the mixing components with a motor. This structure is prone to motor overload due to material impact loads during mixing, reducing equipment lifespan. Therefore, an automatic batching and mixing device for compound fertilizer production is proposed to address these problems. Utility Model Content

Detailed Implementation

[0022] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] Please refer to the following specific embodiment for an automatic batching and mixing device for compound fertilizer production. Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes a frame 1, a dispensing component 2 and a mixing component 3 on the frame 1;

[0024] The batching assembly 2 includes a support plate 201, a batching box 202 is fixedly connected to the top of the support plate 201, a weighing sensor 203 is fixedly connected inside the batching box 202, a weighing plate 204 is placed inside the batching box 202, a material pump 205 is fixedly connected to the outside of the batching box 202, a first feeding pipe 206 is fixedly connected to the input end of the material pump 205, and a second feeding pipe 207 is fixedly connected to the output end of the material pump 205.

[0025] A mixing tank 101 is fixedly connected to the frame 1, and a guide plate 102 is fixedly connected to the frame 1. The guide plate 102 is located below the mixing tank 101 and is designed to be inclined.

[0026] The mixing tank 101 is directly fixed to the frame 1, which enhances the overall stability of the equipment and avoids structural loosening caused by vibration during the mixing process. The inclined design of the guide plate 102 can accelerate the discharge efficiency of the mixed fertilizer, reduce residue, and prevent fertilizer from accumulating and blocking the discharge channel.

[0027] A feed pipe is fixedly connected to the inner top wall of the mixing tank 101, and a discharge pipe is fixedly connected to the inner bottom wall of the mixing tank 101, with the discharge pipe extending above the guide plate 102.

[0028] The feed pipe is connected to the batching component 2, enabling the raw materials to be automatically transported to the mixing tank 101, avoiding errors caused by manual addition; the discharge pipe extends above the guide plate 102, ensuring that the mixed fertilizer can fall accurately onto the guide plate 102, improving the continuity of discharge.

[0029] The support plate 201 is fixedly connected to the rear side of the frame 1, and there are two batching boxes 202, which are symmetrically distributed on the top of the support plate 201.

[0030] The support plate 201 is fixed to the frame 1 at the rear to provide stable support for the batching box 202 and prevent deformation due to the weight of the material. The dual symmetrical batching box 202 design can process two raw materials at the same time, improve batching efficiency, and facilitate expansion to meet the needs of multi-raw material formulations.

[0031] The first feeding pipe 206 extends above the weighing plate 204, which is in contact with the weighing sensor 203. The second feeding pipe 207 extends above the feed pipe, and the side of the second feeding pipe 207 closest to the feed pipe is inclined.

[0032] The first feeding pipe 206 extends above the weighing plate 204 to ensure that the material pump 205 can draw away the weighed compound fertilizer raw materials; the weighing plate 204 is in contact with the weighing sensor 203 to realize real-time weight monitoring and improve the accuracy of batching; the second feeding pipe 207 is inclined on the side near the feed pipe to prevent raw materials from splashing, and at the same time, it uses gravity to assist in conveying and reduce the risk of blockage.

[0033] The mixing component 3 includes a drive motor 301, the output shaft of which is fixedly connected to a first transmission wheel 302, a second transmission wheel 303 is rotatably connected to the frame 1, a belt 304 is connected between the first transmission wheel 302 and the second transmission wheel 303, and a mixing roller 305 is rotatably connected inside the mixing barrel 101.

[0034] The drive motor 301 drives the mixing roller 305 through the belt 304, achieving low noise and high efficiency power transmission; the belt 304 drive has a buffering and vibration absorption effect, reducing the damage to the motor caused by impact loads during the mixing process.

[0035] The drive motor 301 is fixedly connected to the frame 1. The side of the mixing roller 305 away from the drive motor 301 is rotatably connected to the inner wall of the mixing barrel 101, and the other side of the mixing roller 305 is fixedly connected to the second transmission wheel 303.

[0036] One side of the mixing roller 305 is rotatably connected to the inner wall of the mixing barrel 101, and the other side is fixed to the second transmission wheel 303, forming a stable transmission structure. This ensures that the mixing roller 305 rotates inside the mixing barrel 101, improving the uniformity of mixing. At the same time, it can prevent the bearings of the mixing roller 305 from being damaged due to eccentric vibration, thus extending the service life of the equipment.

[0037] Its working principle is as follows: First, the raw materials for compound fertilizer production are put into the weighing plate 204 in the batching box 202. The weight of the raw materials is weighed by the weighing sensor 203. When the raw materials reach the appropriate weight, the material pump 205 is started. Under the action of the first feeding pipe 206 and the second feeding pipe 207, the raw materials are sent from the feed pipe into the mixing tank 101. At the same time, the drive motor 301 is started. Under the drive of the first transmission wheel 302, the second transmission wheel 303 and the belt 304, the mixing roller 305 is rotated in the mixing tank 101 to mix the compound fertilizer raw materials. After the mixing process is completed, the compound fertilizer is discharged from the mixing tank 101 through the discharge pipe. A collection bucket is placed under the guide plate 102 to collect the compound fertilizer conveniently.

[0038] The above technical solution not only achieves precise ingredient proportioning, but also reduces the damage of impact load to the drive motor 301 during the mixing process.

[0039] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
