Abstract
Description
Technical Field
[0001] The utility model discloses a uniform feeding mechanism for producing blended fertilizers. The utility model belongs to the technical field of feeding mechanisms, and in particular relates to the technical field of uniform feeding for producing blended fertilizers. Background Art
[0002] Blended fertilizers are also called BB fertilizers in our daily lives. During the processing, they are mainly made by mixing any of the three nutrients nitrogen, phosphorus and potassium. The three nutrients nitrogen, phosphorus and potassium can be made from unit fertilizers or compound fertilizers, and then made by mechanical mixing. At the same time, there is no significant chemical reaction during the mixing process.
[0003] Therefore, in the process of making blended fertilizers, it is necessary to prepare each material in proportion and then carry out the feeding operation. At present, most of them are weighed in advance, and then added into the feeding hopper together, and finally the materials are transported to the mixing equipment through the feeding hopper for mixing. Although it can be used, the materials are basically separated from each other when feeding. Therefore, it takes a long time to mix them inside the mixing equipment, thereby extending the time required for mixing. In order to shorten the time required for mixing and make different materials more evenly distributed, we propose a uniform feeding mechanism for blended fertilizer production. Utility Model Content

[0010] As an optimal technical solution of the present invention, a feeding servo motor is installed on the surface of the silo away from one end of the discharge pipe, and a spiral conveyor frame is connected to the output shaft of the feeding servo motor through a coupling. The spiral conveyor frame passes through the interior of the silo and enters the interior of the discharge pipe. An arc-shaped bottom is provided at a position inside the silo corresponding to the spiral conveyor frame, and a feed port is provided on the side of the installation box at a position corresponding to the silo.

[0012] Furthermore, the silos are arranged in sequence from top to bottom, and the discharge is carried out synchronously, so that the ratio of various materials inside the mixing silo per unit time is close to the set material ratio during the discharge. Then, under the action of the dispersion rack, the various materials can be distributed and mixed more evenly. Then, by opening the guide rack, the premixed material can pass through the guide rack into the interior of the hopper. Due to the premixing, the mixing time of the mixing equipment is shortened, thereby improving the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The hopper 5 is provided with a guide frame 3 at the bottom end of the mixing hopper 2, and a mounting shaft 7 is provided inside the mixing hopper 2. The hopper 5 is distributed in sequence from top to bottom inside the hopper 1, and a discharge pipe 6 is provided on the side of the hopper 5 that extends into the mixing hopper 2. As a result, when the material is discharged through the discharge pipe 6, the material above can fall into the material below. Since the material is discharged in proportion, the distribution between the materials is relatively uniform, and adjacent discharge pipes 6 are distributed on both sides of the mounting shaft 7. A dispersion frame 8 is installed on the mounting shaft 7 at a position corresponding to the lower part of the discharge pipe 6, ensuring that the rotation of the mounting shaft 7 drives the dispersion frame 8 to rotate, so that the material is stirred during the falling process, so that the materials can be mixed more evenly. The specifications of the feeding servo motor 53, the spiral conveying frame 52 and the discharge pipe 6 inside all the hoppers 5 can be set to the same, thereby reducing the difficulty of setting the feeding servo motor 53.
[0021] A bracket 11 is installed at the bottom of the installation box 1, and an electric control box 4 is installed on the side of the bracket 11. The electric control box 4 is used to set the speed of each feeding servo motor 53, thereby ensuring that the discharge amount of each discharge pipe 6 per unit time is within the interval range.
[0022] The mixing bin 2 includes a guide pipe 21, a storage bin 23 is installed at the bottom end of the guide pipe 21, the top end of the mounting shaft 7 passes through and extends to the outside of the guide pipe 21 and is connected to a stirring motor 22, the bottom end of the mounting shaft 7 is arranged inside the storage bin 23 and is connected to a mixing rack 24, and a discharge port 25 is provided at the bottom end of the storage bin 23, so that the material falls into the interior of the storage bin 23 after being dispersed by the dispersion rack 8 inside the guide pipe 21, and can be further mixed under the action of the mixing rack 24, thereby improving the mixing uniformity of the material.
[0023] The guide frame 3 includes a U-shaped plate 31 for opening and closing the discharge port 25.

A rubber ring 38 is sleeved on the cross bar 37 to tighten the U-shaped plate 31. The electric push rod 36 is shortened by the electric control box 4. Under the action of gravity, the U-shaped plate 31 rotates around the support shaft 33, so that the premixed material inside the storage bin 23 can fall into the inside of the hopper along the direction of the discharge port 25 and the U-shaped plate 31.
[0024] A feeding servo motor 53 is installed on the surface of the silo 5 away from the end of the discharge pipe 6. The output shaft of the feeding servo motor 53 is connected to a spiral conveyor frame 52 through a coupling.
