Description

Technical Field

[0001] The utility model belongs to the technical field of agriculture, and particularly relates to a fertilizer mixer for agriculture. Background Technique

[0002] Fertilizers refer to substances that provide one or more essential nutrients for plants and improve soil properties and soil fertility levels. They are one of the material bases for agricultural production. In order to better meet the growth needs of crops, improve fertilizer utilization efficiency, and reduce waste, it is necessary to mix multiple fertilizers together. A fertilizer mixer for agriculture disclosed in the patent with the publication number CN211189960U mixes fertilizers evenly by setting up a mixing barrel and an auger for double mixing. However, fertilizers are prone to caking and forming lumps during storage, and it is difficult to completely break up the caked fertilizers by mixing, and small fertilizer lumps will be turned over with the fertilizers, resulting in uneven mixing. Content of the Utility Model

[0003] In view of this, while ensuring high-efficiency mixing of fertilizers, the utility model solves the problem that the caked fertilizers cannot be completely broken up during mixing, resulting in a large amount of small fertilizer lumps in the mixed fertilizers, which affects the use.

[0004] The utility model solves the above technical problems through the following technical means:

[0005] A fertilizer mixer for agriculture includes a base, a mixing barrel and a driving component. The driving component is installed on the base, the mixing barrel is rotatably installed on the base, a bushing is fixedly installed on the base, and the mixing barrel is rotatably installed on the bushing. Support rollers are fixedly installed on both sides of the base to support the mixing barrel. The support rollers include a support seat, a fixed shaft and a support wheel. The support seat is fixedly installed on the base, the fixed shaft is installed on the support seat, and the support wheel is installed on the fixed shaft through a bearing. A driving wheel is installed on the output shaft of the driving component, a support is installed on the base, a rotating shaft is installed on the support, a driven wheel is installed at one end of the rotating shaft, the driving wheel is connected to the driven wheel through a belt, a gear is installed at the other end of the rotating shaft, and the gear meshes with a toothed ring to drive the rotation of the mixing barrel. The mixing barrel is provided with a toothed ring and mixing blades, and the mixing blades are spirally distributed in the mixing barrel. A crushing mechanism is arranged at the opening position in the mixing barrel. The crushing mechanism includes a U-shaped sieve barrel, crushing blades and a support rod. The crushing blades include crushing blade leaves and a transmission shaft. The transmission shaft is installed on the driving component. The transmission shaft, the bushing, the mixing barrel and the driving wheel are coaxial. The crushing blade leaves are fixedly installed in a spiral strip shape at one end of the transmission shaft. One end of the U-shaped sieve barrel is connected to the bushing, and the other end is connected to the support rod. The support rod is installed on the base.

[0006] On the basis of the above technical solution, the utility model has also made the following improvements:

[0007] Furthermore, the diameter of the driving wheel is larger than that of the driven wheel. The large wheel drives the small wheel for speed-up transmission, which has higher transmission efficiency and is convenient for improving the stirring efficiency.

[0008] Furthermore, the size of the sieve holes of the U-shaped sieve barrel is 2-5 mm 2 , which is convenient for screening out and crushing oversized fertilizer lumps, and avoiding agglomerated fertilizers from falling into the mixing barrel for mixing, resulting in a large amount of agglomerated fertilizers in the mixed fertilizers.

[0009] Furthermore, the total length of the crushing mechanism does not exceed half of the depth of the mixing barrel, avoiding the mixed fertilizers in the mixing barrel from repeatedly falling into the U-shaped sieve barrel for repeated screening and affecting the efficiency.

[0010] Furthermore, rollers are provided at the bottom of the base, which is convenient for the movement of the mixer.

[0011] The beneficial effects of the present utility model are as follows: The non-agglomerated fertilizers directly fall into the mixing barrel through the U-shaped sieve barrel. The agglomerated fertilizers are screened out in the U-shaped sieve barrel and can be crushed under the extrusion of the crushing blades and then fall into the mixing barrel for mixing, which can avoid a large amount of small agglomerated fertilizers in the mixed fertilizers. The spiral-distributed stirring blades in the mixing barrel can make the mixing barrel rotate clockwise for discharging and counterclockwise for feeding, and at the same time, the mixing barrel performs axial and radial cyclic stirring, which can achieve rapid and uniform mixing of fertilizers.
