Technical Field

[0001] This utility model relates to the field of mixing and mixing technology, specifically a dual-shaft mixing and mixing machine for rice seedling cultivation substrate. Background Technology

[0002] Mixing rice seedling substrate is a crucial step in rice cultivation. Traditional mixers often use a fixed mixing structure, which cannot adjust the mixing angle and position according to different substrate ratios, resulting in uneven mixing, low efficiency, and easy material residue at the bottom of the mixing drum. Although there are some adjustable mixers in the existing technology, their complex structure and inconvenient adjustment make it difficult to meet the mixing requirements of different seedling substrates.

[0003] Therefore, there is an urgent need for a simple mixer with adjustable stirring angle and position to improve stirring efficiency and adaptability. Utility Model Content

The mixing mechanism includes a sliding block, which is U-shaped. Sliding blocks are fixed to both sides of the inner wall of the sliding block, slidingly engaging with the limiting grooves. A threaded hole is provided at the upper end of the sliding block, and a support rod is positioned above the threaded hole. A screw is fixed to the lower end of the support rod and threadedly connected to the threaded hole.

[0006] Furthermore: the two ends of the support rod protrude, and a sleeve is fitted between the two protruding parts of the support rod. Multiple stirring rods are fixed on the outer wall of the sleeve at equal intervals. A fixing pin is threaded to the outer upper end of the sleeve, and the fixing pin abuts against the upper end of the support rod to fix the rotation angle of the sleeve.

[0007] Furthermore: the lower end of the fixing rod is provided with an installation groove, the lower end of the installation groove is provided with a base plate, the upper end of the base plate is fixed with an installation strip, and the installation strip is slidably inserted into the installation groove.

[0008] Furthermore, the bottom plate has an inclined structure on both sides and is slidably disposed against the inner bottom surface of the mixing drum.

[0009] Furthermore, the stirring rod has a circular cross-section, and the stirring rod and the sleeve are integrally formed.
