Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer fermentation, in particular to a multi-axis rotary cutting aeration stirring device for an organic fertilizer fermentation tank used for agricultural vegetable planting. Background Art

[0002] Organic fertilizers are made primarily from organic byproducts such as animal excrement and plant and animal debris, which are fermented and decomposed. Organic fertilizers improve soil quality, enhance soil fertility, increase nutrient availability, purify the soil ecosystem, and ensure high-quality, high-yield, and profitable vegetable production, making them an irreplaceable fertilizer for vegetable cultivation.

[0003] The patent application number CN202311196856.6 discloses a fermentation tank stirring device, including a moving mechanism, a loading mechanism, a connecting mechanism and a stirring mechanism, wherein the loading mechanism is fixedly connected to the top of the moving mechanism, the connecting mechanism is threadedly connected to the top of the moving mechanism, the stirring mechanism is rotatably connected to the inside of the loading mechanism, and the stirring mechanism includes a main stirring unit and an auxiliary stirring unit, the main stirring unit is rotatably connected to the inside of the loading mechanism, and the auxiliary stirring unit is movably connected to the surface of the main stirring unit. The invention is provided with a cover plate threadedly connected to the top of the rotating block, wherein the thread grooves cooperate with each other so that the two form a state of mutual rotation without interfering with each other, and then the connecting rod and the threaded cap are threadedly connected to fix the cover plate, cooperate with the driving seat to drive the fermentation tank to rotate, and the internal raised block drives the fermentation to rotate, and rotates in the opposite direction to the internal stirring frame, so that the device improves the stirring effect when in use.

[0004] The current mainstream solution generally adopts single-axis stirring technology, with a fixed stirring rod angle and insufficient stirring. When stirring and mixing materials such as straw and feces in the organic fertilizer fermentation tank, large pieces of materials are not sufficiently broken, and the shear blade angle cannot be adjusted according to the material characteristics. For example, when processing hard materials such as rice husks, blade wear is likely to increase. At the same time, during fermentation, air is not introduced into the fermentation tank, which reduces the activity of microorganisms and affects the fermentation effect.

[0005] In view of this, we propose a multi-axis rotary cutting aeration stirring device for an organic fertilizer fermentation tank used in agricultural vegetable cultivation. Summary of the Invention

[0006] In order to overcome the defects in the prior art, the purpose of the present invention is to provide a multi-axis rotary cutting aeration and stirring device for an organic fertilizer fermentation tank for agricultural vegetable planting. The spiral blades are driven by a motor to drive the bottom material to the upper layer, and at the same time drive the cross-cutting piece to rotate in the opposite direction. The vertical cutting piece is driven by a belt to rotate in the same direction. The cross-cutting piece and the vertical cutting piece rotate relative to each other to effectively shear the material. At the same time, an aeration piece is arranged at the bottom end of the tank body to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides a multi-axis rotary cutting, aeration and stirring device for an organic fertilizer fermentation tank for agricultural vegetable cultivation, comprising a tank body, a tank cover, a main rotating shaft rotatably connected to the center of the tank body, cross-cutting members and vertical cutting members rotatably connected to the tank body and alternately arranged around the main rotating shaft, and an aeration member installed at the bottom end of the tank body. Spiral blades are welded to the side walls of the main rotating shaft, and the rotation of the main rotating shaft drives the adjacent cross-cutting members and vertical cutting members to rotate in opposite directions. This setting uses spiral blades to drive the bottom layer of materials to the upper layer, and the oppositely rotating cross-cutting pieces and vertical cutting pieces shear the materials, making the materials more finely divided, which is conducive to the fermentation of the materials.

The aeration component comprises an aeration plate rotatably connected to the bottom end of the tank body, a plurality of air outlets arranged on the top of the aeration plate, and an air blower connected to the aeration plate through a pipeline.

[0008] This setting injects air into the tank when the material is stirred and sheared, increasing the activity of microorganisms and improving the fermentation effect.

The driving gear is engaged with several driven gears, and several of the vertical cutting shafts are connected to the main rotating shaft through belts.

[0012] In this setting, the driving gear rotates to drive the driven gear, so that the cross-cutting piece rotates in the opposite direction of the main shaft. Through the belt drive connection, the vertical cutting piece rotates in the same direction as the main shaft, and thus the cross-cutting piece rotates in the opposite direction to the vertical cutting piece.

[0013] As a further improvement of the present technical solution, the cross-cutting knife includes an arc-shaped blade and a worm gear installed at the tail end of the arc-shaped blade. Several worm gears are integrally formed on the first adjusting rod. The tail end of the arc-shaped blade extends into the cross-cutting axis and the worm gear on it engages with the corresponding worm gear.

[0014] This setting rotates the first adjusting rod, which drives the arc-shaped blade to deflect its angle through the meshing worm and worm wheel.

[0015] As a further improvement of the present technical solution, a first handle is welded and fixed to the top end of the first adjusting rod after extending out of the tank cover, serrations are provided on the cutting edge of the arc-shaped blade, and a limiting ring block is provided on the handle of the arc-shaped blade.

[0016] The first handle of this arrangement facilitates the rotation of the first adjusting lever, the saw teeth can effectively shear hard materials, and the limiting ring block limits the arc-shaped blade when it rotates.

[0017] As a further improvement of the present technical solution, a threaded rod is rotatably connected inside the fixed rod, and both sides of the upper and lower end faces of the vertical cutter are hinged to the threaded blocks threadedly connected to the threaded rod through a hinged rod, and both sides of the upper and lower end faces of the vertical cutter are welded and fixed with connecting rods that are compatible with the hinged rod.

[0020] In this setting, the second adjusting rod rotates, driving the first bevel gear to rotate, causing the second bevel gear to rotate accordingly, and then the threaded rod rotates.

[0021] As a further improvement of the present technical solution, a threaded hole adapted to the threaded rod is provided on the threaded block, and the threaded blocks connected to the hinged rods on both sides of the fixed rod move in opposite directions on the threaded rod.

[0022] This setting rotates the threaded rod, causing the threaded blocks connected to the hinged rod on one side to slide in the same direction, while those on the other side slide in the opposite direction, thereby pushing the vertical cutter to deflect.

[0023] As a further improvement of the present technical solution, a second handle is welded and fixed to the top of the second adjusting rod after extending out of the tank cover, and a long hole is opened on the top of the fixing rod to match the hinge column at the top of the threaded block.

[0025] As a further improvement of the present technical solution, a mounting seat adapted to the bottom end of the main shaft is welded and fixed at the center of the top end of the aeration disc, and the mounting seat and the bottom end of the main shaft are fixed by fastening bolts.

[0026] This setting fixes the aeration plate on the main shaft so that the aeration plate rotates as the main shaft rotates, thereby evenly diffusing the air inside the tank.

[0027] Compared with the prior art, the present invention has the following beneficial effects: 1. The multi-axis rotary cutting aeration stirring device of the organic fertilizer fermentation tank for agricultural vegetable planting drives the main shaft to rotate through the motor, and the spiral blades drive the bottom material to the upper layer. At the same time, the main shaft rotates through the driving gear and the driven gear to drive the cross-cutting piece to rotate in the opposite direction, and drives the vertical cutting piece to rotate in the same direction through the belt, so that the cross-cutting piece and the vertical cutting piece rotate relative to each other. The multi-axis cooperates to shear the material more finely, which is convenient for fermentation.

[0028] 2. The multi-axis rotary cutting, aeration and stirring device of the organic fertilizer fermentation tank for agricultural vegetable cultivation adjusts the deflection angle of the cross-cutting knife under the action of the worm and worm wheel by rotating the first adjusting rod, and drives the threaded rod to rotate under the action of the first bevel gear and the second bevel gear by rotating the second adjusting rod, and then adjusts the deflection angle of the vertical cutting knife under the action of the hinged rod. This can avoid the blade from directly facing the material when shearing hard materials, thereby reducing blade wear.

[0029] 3. The multi-axis rotary cutting aeration and stirring device of the organic fertilizer fermentation tank for agricultural vegetable planting uses an air blower to transport air through a pipe to the aeration plate, and then enters the tank body from the air outlet, increasing the activity of microorganisms in the tank body and helping to improve fermentation efficiency.
