Description

Technical Field

[0001] The utility model relates to the technical field of saline-alkali land conditioner preparation equipment, in particular to a mixing device for preparing saline-alkali land conditioner. Background Technique

[0002] Saline-alkali land is a type of salt accumulation, which means that the salt content in the soil affects the normal growth of crops. During the utilization of saline-alkali land, simply speaking, it can be divided into light saline-alkali land, medium saline-alkali land and heavy saline-alkali land. Light saline-alkali land refers to the emergence rate of 70%-80% and the salt content below 0.3‰; heavy saline-alkali land refers to the salt content exceeding 0.6‰ and the emergence rate below 50%.

[0003] Before using saline-alkali land for planting, it is necessary to transform the saline-alkali land. When transforming, it is necessary to prepare the corresponding improvement agent according to the soil quality of the saline-alkali land. After the improvement agent is prepared, the soil of the saline-alkali land is turned over, and the improvement agent is evenly sprayed on the saline-alkali land during the soil-turning process, so that the improvement agent neutralizes the salt in the saline-alkali land, making the saline-alkali land meet the planting requirements.

[0004] However, when producing the improvement agent, the raw materials are generally directly poured into a stirring kettle or a stirrer, and then the raw materials are stirred by the stirring kettle or the stirrer. The mixing of the raw materials is completed in the stirring kettle or the stirrer, which takes a long time and reduces the mixing efficiency of the raw materials. Therefore, it does not meet the existing requirements. For this reason, we propose a mixing device for preparing saline-alkali land conditioner. Content of the Utility Model

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] As Figures 1 to 3 shown, a mixing device for preparing a saline-alkali land conditioner, a discharge pipe 2 is fixed to the bottom end of a stirring barrel 1, a cover plate is detachably installed at the top end of the stirring barrel 1, a stirring main shaft 3 is rotatably installed through the middle of the cover plate, stirring paddles 4 are fixed to the outer side of the stirring main shaft 3, a stirring motor 5 is connected to the top end of the stirring main shaft 3, a feed hopper 7 is installed above the cover plate, a feed connection pipe 9 is fixed to the bottom end of the feed hopper 7, the bottom end of the feed connection pipe 9 penetrates through the cover plate and a feed premixing pipe 10 is fixed to the bottom end thereof, and the feed premixing pipe 10 is spirally distributed around the stirring main shaft 3. The raw materials are mixed and added into the interior of the stirring barrel 1 through the feed hopper 7, the feed connection pipe 9, and the feed premixing pipe 10. The feed premixing pipe 10 increases the formation of the raw material flow and enables the raw materials to be preliminarily mixed in the feed connection pipe 9 and the feed premixing pipe 10.

[0020] A plurality of premixing guide strips 11 are provided inside both the feed connection pipe 9 and the feed premixing pipe 10. The premixing guide strips 11 are circularly arrayed around the pipe axes of the feed connection pipe 9 and the feed premixing pipe 10. The premixing guide strips 11 are spirally wound in close contact with the inner walls of the feed connection pipe 9 and the feed premixing pipe 10. The inner side of the premixing guide strips 11 is an arc surface. The raw materials of the improving agent entering the feed connection pipe 9 and the feed premixing pipe 10 are guided by the premixing guide strips 11 spirally wound inside the feed connection pipe 9 and the feed premixing pipe 10, so that the raw materials of the improving agent flow spirally in the feed connection pipe 9 and the feed premixing pipe 10, and the raw materials of the improving agent are preliminarily mixed during the flowing process.

[0021] The inner bottom end of the stirring barrel 1 is in an inverted conical shape, and a solenoid valve is provided inside the bottom end of the discharge pipe 2. The stirring barrel 1 with an inverted conical inner bottom end can ensure that all the mixed improving agent enters the discharge pipe 2, and avoid waste caused by the remaining of the mixed improving agent inside the stirring barrel 1.

[0022] A support frame 6 is installed below the stirring motor 5. The support frame 6 is fixed to the cover plate and supports the stirring motor 5. Four symmetrically distributed support rods 8 are fixed to the bottom end of the feed hopper 7, and the bottom ends of the support rods 8 are fixed to the cover plate. The stirring motor 5 is supported by the support frame 6 to ensure the stable position of the stirring motor 5 and avoid the inclination of the stirring motor 5, and the feed hopper 7 is supported by the support rods 8 to ensure that the feed hopper 7 does not fall off the cover plate.

[0023] Working principle: First, the improved agent raw materials with mixing are simultaneously added into the inner side of the feeding funnel 7. The improved agent raw materials enter the feeding funnel 7 and then enter the feeding connection pipe 9 from the bottom end of the feeding funnel 7. Subsequently, the improved agent raw materials flow along the feeding connection pipe 9 into the feeding premixing pipe 10. The improved agent raw materials flow in the spirally distributed feeding premixing pipe 10 and enter the stirring barrel 1 from the bottom end of the feeding premixing pipe 10. When the improved agent raw materials flow in the feeding connection pipe 9 and the feeding premixing pipe 10, the premixing material diversion strips 11 spirally wound on the inner sides of the feeding connection pipe 9 and the feeding premixing pipe 10 divert the improved agent entering the feeding connection pipe 9 and the feeding premixing pipe 10, so that the raw materials of the improved agent flow spirally in the feeding connection pipe 9 and the feeding premixing pipe 10. Moreover, the arc surface inside the premixing material diversion strip 11 guides the raw materials of the improved agent in the spiral flow towards the center of the feeding connection pipe 9 and the feeding premixing pipe 10, so that the raw materials of the improved agent are preliminarily mixed during the flowing process. After the preliminarily mixed improved agent raw materials enter the stirring barrel 1, the stirring motor 5 is powered on and started to drive the stirring main shaft 3 and the stirring paddle 4 to rotate, and the stirring paddle 4 is used to mix and stir the preliminarily mixed improved agent. The raw materials are preliminarily mixed during the feeding process, reducing the time required for subsequent mixing and stirring inside the stirring barrel 1 and improving the mixing and stirring efficiency of the improved agent.
