[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1 , Figure 2 As shown, an organic fertilizer fermentation device for planting crops comprises a mechanism shell 1, four rectangularly distributed supporting feet 2 are fixedly connected to the lower surface of the mechanism shell 1 near the four corners, a fermentation tank 3 is fixedly connected to the inner side near the upper side of the mechanism shell 1, a plurality of evenly distributed partitions 4 are connected to the inner lower surface of the mechanism shell 1, a water pipe 5 is fixedly connected to the front side near the left side of the mechanism shell 1 and the rear side near the right side of the mechanism shell 1, a stirring mechanism 6 is fixedly connected to the middle boss on the right side of the mechanism shell 1, and a discharging mechanism 7 is fixedly connected to the right side of the mechanism shell 1 near the rear lower boss.

[0029] It should be noted that rubber pads are fixedly connected to the lower sides of the four supporting legs 2 to reduce vibrations generated when internal components are in operation.

[0030] like Figure 3 As shown, the upper side of the partition 4 is fixedly connected to the outer wall of the fermentation tank 3 near the lower side, and the partition 4 forms a coil-shaped cavity at the inner bottom of the mechanism housing 1.

[0031] It should be noted that hot water is injected from the water pipe 5 on the rear right side and discharged from the water pipe 5 on the front left side. The hot water heats the inside of the fermentation tank 3 so that the inside of the fermentation tank 3 reaches the optimal fermentation temperature. The arrangement of the partitions 4 is used to extend the time that the hot water remains in the mechanism housing 1 as much as possible.

[0032] like Figure 4 , Figure 5 As shown, the stirring mechanism 6 includes a first motor 61, the lower surface of the first motor 61 is fixedly connected to the middle boss on the right side of the mechanism housing 1, the output end of the first motor 61 is fixedly connected to a rotating rod 62, and the left end of the rotating rod 62 is fixedly connected to a first stirring frame 63.

[0033] It should be noted that the first motor 61 drives the rotating rod 62 to rotate, and when the rotating rod 62 rotates, it drives the first stirring frame 63 to rotate, and when the first stirring frame 63 rotates, the material inside the fermentation tank 3 is stirred.

[0034] like Figure 4 As shown, the second stirring racks 64 are rotatably connected to the left and right sides of the first stirring rack 63 near the lower side.

[0035] It should be noted that a receiving groove is provided on the front side of the second stirring frame 64, and the shape of the receiving groove is consistent with the shape of the first stirring frame 63. When the first stirring frame 63 is rotated and the first stirring frame 63 is movably sleeved into the inner side of the receiving groove, the first stirring frame 63 and the second stirring frame 64 form a complete plate-like component.

[0036] like Figure 1 , Figure 5As shown, a fixed sleeve 65 is fixedly connected to the right side near the upper end of the second stirring frame 64, the outer side of the rotating rod 62 is movably sleeved on the inner side of the fixed sleeve 65, a circular plate 66 is fixedly connected to the outer wall of the fixed sleeve 65 near the right side, and the circular plate 66 is located on the right side of the mechanism housing 1, and a plurality of annularly distributed limiting rods 67 are fixedly connected to the right side near the edge of the circular plate 66, and a fixed ring 68 is movably sleeved on the outer wall of the limiting rod 67, and a spring 69 is movably sleeved on the outer walls of the plurality of limiting rods 67, and the spring 69 is located on the left side of the fixing ring 68, a limiting ring 610 is fixedly connected to the outer wall of the rotating rod 62 near the right side, and the left side surface of the limiting ring 610 fits the right side surface of the fixed sleeve 65, and four annularly distributed latching teeth 611 are fixedly connected to the outer wall of the fixed sleeve 65 near the right side and the outer wall of the limiting ring 610, and the outer wall of the latching teeth 611 is movably sleeved in the latching groove opened on the inner side of the fixing ring 68.

[0037] It should be noted that when the latch teeth 611 on the outside of the fixed sleeve 65 and the latch teeth 611 on the outside of the limiting ring 610 are simultaneously inserted into the slots on the inside of the fixed ring 68, the fixed sleeve 65 and the rotating rod 62 remain relatively still. When the first motor 61 drives the first stirring frame 63 to rotate, it can drive the second stirring frame 64 to rotate synchronously, pushing the fixed ring 68, so that the latch teeth 611 on the outside of the limiting ring 610 are disengaged from the fixed ring 68, resulting in the fixed sleeve 65 not driving the rotating rod 62 to rotate synchronously when rotating.

[0038] like Figure 2 , Figure 6 and Figure 7 As shown, the discharging mechanism 7 includes a second motor 71, the front side of the second motor 71 is fixedly connected to the boss on the right side of the mechanism housing 1 near the rear lower side, the output end of the second motor 71 is fixedly connected to the first gear 72, the right side of the mechanism housing 1 is rotatably connected to a ring gear 73 near the edge, and the front upper side of the first gear 72 is meshed and connected with the rear lower side of the ring gear 73, the left side of the mechanism housing 1 is movably sleeved with a cover 77, the right side of the cover 77 is fixedly connected with a movable screw 76 near the front and rear sides, and the outer wall of the movable screw 76 is movably sleeved on the bosses on the front and rear sides of the mechanism housing 1, the inner sides of the two movable screws 76 are threadedly connected with screw rods 74, the outer wall of the screw rod 74 is rotatably connected to the right wall of the boss on the front and rear sides of the mechanism housing 1 near the right side, the right ends of the two screw rods 74 are fixedly connected with second gears 75, and the side of the second gear 75 close to each other is meshed and connected with the outer side of the ring gear 73.

[0039] It should be noted that the second motor 71 drives the first gear 72 to rotate, and when the first gear 72 rotates, it drives the ring gear 73 to rotate, and when the ring gear 73 rotates, it drives the movable screw 76 to rotate, and when the second gear 75 rotates, it drives the screw rod 74 to rotate, and when the screw rod 74 rotates, the movable screw 76 moves laterally along the screw rod 74, thereby driving the cover 77 to move laterally, thereby controlling the opening or closing of the mechanism housing 1 by the cover 77.

[0040] like Figure 2 , Figure 6 and Figure 7 As shown, the outer walls of the two movable screw tubes 76 are fixedly connected with four annularly distributed clamping strips 78, and the outer sides of the clamping strips 78 are slidably connected in the sliding grooves provided on the inner walls of the bosses on the front and rear sides of the mechanism housing 1.

[0041] It should be noted that the clamping strip 78 is slidably connected in the slide groove, which is used to limit the clamping strip 78 and prevent the moving screw 76 from moving too far out of the inner side of the bosses on the front and rear sides of the mechanism housing 1, resulting in the screw rod 74 being threadedly connected only to the inner side of the moving screw 76 near the right side, while the left end of the moving screw 76 is fixed, so that the overall force of the moving screw 76 is uneven, causing the right half of the moving screw 76 to twist itself, resulting in a reduction in the service life of the moving screw 76.

[0042] like Figure 6 As shown, two pull rods 79 symmetrically distributed frontward and rearward are fixedly connected to the right side of the cover 77 near the edge, and a push plate 710 is fixedly connected to the right end of the pull rod 79. The outer side of the push plate 710 is movably sleeved on the inner side of the fermentation tank 3 near the right side.

[0043] It should be noted that when the cover 77 moves, it drives the pull rod 79 to move, causing the pull rod 79 to push or pull the push plate 710, so that the push plate 710 pushes the material inside the fermentation tank 3 out. The shape of the notch opened on the left side of the push plate 710 near the bottom is consistent with the shape of the screw rod 74.

[0044] The working principle of the utility model is as follows: first, when the latch teeth 611 on the outside of the fixed sleeve 65 and the latch teeth 611 on the outside of the limiting ring 610 are simultaneously inserted into the latch grooves on the inside of the fixed ring 68, the fixed sleeve 65 and the rotating rod 62 remain relatively still, and when the first motor 61 drives the first stirring frame 63 to rotate, the second stirring frame 64 can be driven to rotate synchronously, pushing the fixed ring 68, so that the latch teeth 611 on the outside of the limiting ring 610 are separated from the fixed ring 68, so that when the fixed sleeve 65 rotates, the rotating rod 62 will not be driven to rotate synchronously, and a receiving groove is provided on the front side of the second stirring frame 64, and the shape of the receiving groove is consistent with the shape of the first stirring frame 63, and the first stirring frame 63 is rotated. When the first stirring frame 63 is movably sleeved into the inner side of the receiving tank, the first stirring frame 63 and the second stirring frame 64 form a complete plate-like component. By pushing the fixing ring 68 and then rotating the fixing ring 68 half a circle, the first stirring frame 63 is movably sleeved into the inner side of the second stirring frame 64, so that the first stirring frame 63 and the second stirring frame 64 form a complete plate-like structure, so that the space occupied by the first stirring frame 63 and the second stirring frame 64 inside the fermentation tank 3 is convenient for taking out the organic matter from the inner side of the fermentation tank 3. Finally, the second motor 71 drives the first gear 72 to rotate, and the first gear 72 rotates to drive the gear ring 73 to rotate, and the gear ring 7 When the second gear 75 rotates, it drives the movable screw tube 76 to rotate. When the second gear 75 rotates, it drives the screw rod 74 to rotate. When the screw rod 74 rotates, the movable screw tube 76 moves laterally along the screw rod 74, thereby driving the cover 77 to move laterally, so as to control the opening or closing of the mechanism housing 1 by the cover 77. The card strip 78 is slidably connected in the slide groove to limit the card strip 78 to prevent the movable screw tube 76 from moving too far out of the inner side of the boss on the front and rear sides of the mechanism housing 1, resulting in the screw rod 74 being threadedly connected only to the inner side of the movable screw tube 76 near the right side, and the left end of the movable screw tube 76 is fixed, so that the overall force of the movable screw tube 76 is uneven, causing the right half of the movable screw tube 76 to move automatically. The body of the movable screw tube 76 is twisted, resulting in a reduction in the service life of the movable screw tube 76. When the cover 77 moves, it drives the pull rod 79 to move, causing the pull rod 79 to push or pull the push plate 710, so that the push plate 710 pushes the material inside the fermentation tank 3 out. The notch on the left side of the push plate 710 near the bottom is consistent with the shape of the screw rod 74. By movably sleeved on the inner side of the screw rod 74, the gear ring 73 and the screw rod 74 are at the position with the lowest potential energy. The second motor 71 drives the screw rod 74 to rotate, causing the cover 77 to drive the push plate 710 to push the organic fertilizer out from the inner side of the fermentation tank 3, thereby achieving the purpose of automatic discharging, which is simple, efficient, convenient and fast.
