[0002] With the rapid development of modern agriculture, macronutrient water-soluble fertilizer as a kind of efficient, environmentally friendly fertilizer type, is more and more widely used in agricultural production.

[0003] In the mixing process of existing macronutrient water-soluble fertilizer, various different raw materials are poured into the mixing barrel for mixing, but due to the difference in physical properties (such as particle size, shape, density, etc.) of the raw materials, they will naturally accumulate at different positions in the mixing barrel. For example, raw materials with higher density tend to settle at the bottom of the mixing barrel, while raw materials with lower density tend to accumulate at the top. This stratification phenomenon leads to ineffective contact and mixing between different layers of raw materials at the beginning of mixing, making the mixing process slow and uneven. At the same time, the existing mixing device mostly adopts a simple stirring paddle stirring method, relying on the rotation of the stirring paddle to drive the movement of the surrounding materials to achieve mixing. This stirring method lacks a mechanism for forced material circulation, and cannot effectively lift the raw materials at the bottom of the mixing barrel to the upper layer, nor can it fully transport the raw materials at the upper layer to the lower layer. During stirring, the materials mainly move in the local area near the stirring paddle, while the area far from the stirring paddle is prone to form a stirring dead zone, resulting in insufficient mixing of materials.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0022] Please refer to the drawings of the embodiments of the utility model Figures 1-6 The embodiment of the utility model discloses a kind of macroelement water-soluble fertilizer high-efficiency mixing device: including base 1, the base 1 is rotatably connected with overturning frame 2, the overturning frame 2 is fixedly connected with mixing barrel 3, stirring cavity 4 is equipped in the mixing barrel 3, stirring frame 5 is rotatably connected in the stirring cavity 4, material conveying pipe 6 is equipped in the stirring cavity 4, the material conveying pipe 6 is coaxially fixedly connected with the mixing barrel 3, material conveying cavity 7 is equipped in the material conveying pipe 6, feeding port 8 is equipped in the material conveying pipe 6 lower end, the material conveying cavity 7 is communicated with the stirring cavity 4 by feeding port 8, discharging port 9 is equipped in the material conveying pipe 6 upper end, conveying assembly 10 for lifting material is equipped in the material conveying cavity 7.
[0023] The base 1 is horizontally arranged at the bottom, and is fixed on the ground or a table as a fixed support body. The base 1 has a rib plate extending upward at the front and rear. The middle part of the turnover frame 2 is rotatably arranged at the upper end of the rib plate. The rib plate provides sufficient space between the turnover frame 2 and the base 1, so that the turnover frame 2 can change the angle by more than 90 degrees. The mixing barrel 3 is arranged in an open-top structure. In the initial state, the mixing barrel 3 is vertically arranged on the turnover frame 2, and the opening of the mixing barrel 3 faces upward. At this time, the fertilizer to be mixed can be added into the mixing barrel 3 from the top. The fertilizer to be mixed enters the stirring cavity 4 from the opening of the mixing table to be stirred. The opening of the mixing barrel 3 is also the discharge port 9 of the mixing barrel 3. After the fertilizer is mixed, the opening of the mixing barrel 3 is turned downward by the rotation of the turnover frame 2, so as to achieve the purpose of pouring. The mixing barrel 3 is coaxially arranged with the conveying pipe 6. The height of the conveying pipe 6 is lower than the barrel opening of the mixing barrel 3. Under the segmentation of the conveying pipe 6, the conveying pipe 6 forms a conveying cavity 7 with a smaller diameter inside. The conveying pipe 6 is a tubular stirring cavity 4 with a larger diameter outside. The bottom of the stirring cavity 4 is communicated with the conveying cavity 7 through the feeding port 8. When the fertilizer raw material is in the stirrer, the fertilizer raw material enters the conveying cavity 7 through the reducing port. The conveying assembly 10 in the raw material cavity moves the fertilizer raw material at the bottom upward along the conveying cavity 7. Finally, the fertilizer raw material is conveyed to the upper position of the stirring cavity 4 through the discharge port 9. In this way, the upper and lower fertilizers in the stirring cavity 4 can be mixed more quickly, and the mixing efficiency is improved.
[0024] The conveying assembly 10 plays a role in material circulation. The conveying assembly 10 conveys the fertilizer raw material at the lower layer of the stirring cavity 4 upward, so as to improve the moving range and moving speed of the raw material in the stirring cavity 4, avoid the same raw material from being accumulated together, improve the mixing efficiency, and ensure that the fertilizer raw material can be stably discharged from the feeding port 8. The bottom of the mixing barrel 3 is conical, so that the raw material at the bottom can be better moved to the conveying assembly 10 in the conveying cavity 7. The conveying assembly 10 is composed of a driving shaft 1001 and a spiral blade 1002. The two ends of the driving shaft 1001 are respectively supported by a first bearing bracket 1003 and a second bearing bracket 1004. The first bearing bracket 1003 is arranged at the opening of the mixing barrel 3. A conical hopper is arranged outside the first bearing bracket 1003, so as to facilitate pouring the raw material into the mixing barrel 3.
[0025] The second bearing bracket 1004 on the driving shaft 1001 is arranged on the turnover frame 2. The second bearing bracket 1004 and the mixing barrel 3 rotate synchronously with the turnover frame 2. There is a gap between the second bearing bracket 1004 and the mixing barrel 3. The motor and the speed reducer for driving the driving shaft 1001 to rotate are arranged in the gap. The mixing barrel 3 is closely arranged on the turnover frame 2. The other side of the mixing barrel 3 is fixed by a steel hoop 11. The two ends of the steel hoop 11 are fixed on the turnover frame 2.
[0026] The rotating shaft 12 on both sides of the turnover frame 2 is embedded in the shaft seat of the base 1 to realize horizontal rotation freedom, and the hydraulic telescopic rod 13 is hingedly connected to the side wall of the turnover frame 2 at one end and to the base 1 at the other end; when the telescopic rod is elongated, the turnover frame 2 is pushed to rotate around the rotating shaft 12 to an inclined state (such as 60°), so that the outlet of the mixing cylinder 3 is downward for discharging; and when the telescopic rod is retracted, the turnover frame 2 is reset to the vertical mixing position, thereby realizing the switching of the mixing / discharging double stations and avoiding the safety risk of manual pouring.
[0027] In order to reduce the configuration of power sources in the device, the stirring frame 5 is selected as an upside-down U-shaped stirring frame 5, the stirring frame 5 is welded with the driving shaft 1001, and the two sides of the stirring frame 5 are respectively provided with the first stirring block 14 and the second stirring block 15; the first stirring block 14 and the second stirring block 15 are the same in structure, and the first stirring block 14 and the second stirring block 15 on the left and right sides are staggered and distributed; when the stirring frame 5 rotates, the outer sides of the first stirring block 14 and the second stirring block 15 are attached to the inner wall of the mixing cylinder 3, so that the first stirring block 14 and the second stirring block 15 staggered and distributed can have a larger contact area with the inner wall of the mixing cylinder 3, the fertilizer on the inner wall of the mixing cylinder 3 can be scraped off, the fertilizer adhered to the inner wall of the mixing cylinder 3 can be avoided, the workload of subsequent cleaning work can be reduced, and meanwhile, the staggered distribution can increase the contact range of the fertilizer raw materials and improve the flowability of the internal raw materials and accelerate the mixing of the raw materials.
[0028] The first stirring block 14 and the second stirring block 15 are the same in structure and are each composed of a connecting rod 16 and two conical stirring heads 17; the tips of the conical stirring heads 17 are directed to the direction in which the stirring frame 5 rotates, so as to reduce the resistance when the stirring frame 5 rotates.
[0029] The overall working process of the utility model is as follows: firstly, the mixing cylinder 3 is kept in a vertical state through overturning, and raw materials are added into the mixing cylinder 3; the raw materials in the lower layer of the stirring cavity 4 enter the material conveying cavity 7 from the feeding port 8, the driving shaft 1001 and the spiral blade 1002 in the material conveying cavity 7 drive the raw materials to be lifted to the upper layer, the raw materials fall back to the upper part of the stirring cavity 4 from the discharging port 9, and when the driving shaft 1001 and the spiral blade 1002 lift the materials, the mixing frame performs the mixing work in the stirring cavity 4; the raw materials falling back to the upper part of the stirrer can be quickly mixed with the raw materials originally in the upper layer of the stirring cavity 4; after the mixing is completed, the driving shaft 1001 is stopped, the hydraulic telescopic rod 13 is elongated to the limit position, the mixing cylinder 3 is inclined by 60°, and the fertilizer slides out along the cylinder wall.
[0030] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
