Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an integrated machine for rotary tillage and fertilization of organic fertilizer. Background Technology

[0002] Rotary tillers are agricultural tillage machines that cut, crush, mix, and blend soil using high-speed rotating blades, making them more efficient than manual tillage. Fertilizer applicators automatically apply liquid or solid fertilizers to the soil using specialized machinery, making it faster than manual fertilization. Currently, operating rotary tillers and fertilizer applicators simultaneously consumes more labor and has relatively lower efficiency. Separate operation takes more time and can lead to low fertilizer utilization due to variations in the order of operation, time, and working environment. Therefore, this application proposes an integrated rotary tiller and fertilizer applicator for organic fertilizer. Utility Model Content

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] like Figures 1-4 As shown, an organic fertilizer rotary tillage and fertilization machine includes a rotary tiller 1 and a fertilization device 2. The fertilization device 2 is fixed above the rotary tiller 1 by a bracket 19. The discharge port of the fertilization device 2 is located in front of the rotary tiller 1, that is, the discharge port at the front end of the fertilization device 2 is further forward than the front end of the rotary tiller, so that the fertilizer is spread on the soil and then tilled by the rotary tiller.

[0030] The main body of the rotary tiller 1 is a rectangular steel plate. Two steel clamps are welded to each side of the front long side of the rectangular steel plate near the center point, each clamp having three screw holes. Two steel clamping blocks are welded to each side of the rear long side of the rectangular steel plate near the short side, each clamping block having one screw hole. The main body of the traction frame 10 consists of two inverted L-shaped steel structures. The upper end has a clamping plate with three screw holes, and the lower end has a clamping plate with one screw hole. The lower clamping plate is bolted to the rear screw holes of the front long side steel clamping plate of the rotary tiller 1. A steel beam is bolted to the rear screw holes of the upper clamping plate, and the other end of the steel beam is bolted to the rear long side steel clamping block of the rear rectangular steel plate of the rotary tiller 1. The two clamps (four screw holes) at the upper end of the traction frame 10 and the two clamps (four screw holes each) on the long side of the front end of the rectangular steel plate of the rotary tiller 1 form the three connection points between the rotary tiller 1 and agricultural vehicles such as tractors. By adjusting the length of the connection mechanism, the height of the rotary tiller 1 from the ground can be adjusted, thereby adjusting the rotary tillage depth.

[0031] The rotary tiller 1 has covers 16 welded to the short sides of its rectangular steel plate. These covers 16 shield the tiller from soil splashing to the sides and protect the operator. The rotary tiller roller 12 is located below the rectangular steel plate of the rotary tiller 1. The main body of the rotary tiller roller 12 is a rotary tillage shaft 13, which is mounted on the covers 16 and rotates counterclockwise. Several rotary tillage blade shafts 14 are welded to the rotary tillage shaft 13, and four rotary tillage blades 15 are welded to each shaft. The rotary tillage blades 15 can be curved blades to achieve rotary tillage of the soil; furthermore, L-shaped blades can be used for deeper tillage than curved blades. A transmission device 11 is mounted on the rectangular steel plate of the rotary tiller 1. The front end of the transmission device 11 has a shaft hole, which connects to agricultural vehicles such as tractors via the shaft. This mechanical structure enables power transmission from the agricultural vehicle to the rotary tiller roller 12 in coordination with the rotary tiller roller 12.

[0032] A mudguard 17 is installed on the rear side of the rectangular steel plate of the rotary tiller 1. A movable hollow steel tube is installed at the front end of the mudguard 17, and a steel shaft is installed inside the hollow steel tube. The steel shaft is welded to the cover 16, allowing the mudguard 17 to rotate based on the steel shaft. A steel block with a screw hole is welded to each end of the mudguard 17. One end of the movable bolt 18 is inserted into the steel block, and the other end is inserted into the semi-circular screw hole steel block with a locking buckle welded to the rear end of the rectangular steel plate of the rotary tiller 1. By rotating the movable bolt 18, the rotation angle of the mudguard 17 based on the steel shaft can be locked, thereby controlling the direction of soil flow and protecting the operator's safety.

[0033] The rotary tiller 1 has a support frame 19 fixed to the short sides of the rectangular steel plate by welding and bolts. The support frame 19 is mainly divided into two side supports, with a crossbeam welded in the middle, and a fertilizer applicator 2 fixed on the top by a screw. The support frame 19 is designed with a certain degree of inclination, with the front end higher and the rear end lower, so that the front end of the fertilizer applicator 2 is tilted upwards, and the fertilizer is piled up to the rear end, so that it will not be automatically discharged due to gravity.

[0034] The main body of the fertilizer applicator 2 consists of a fertilizer box 20 and a conveyor belt 21. The fertilizer box 20 is connected to the support 19 by bolts through welded steel bars on its side. The upper part of the fertilizer box 20 is unobstructed and is used to hold fertilizer; the lower front part of the fertilizer box 20 is unobstructed and is used for discharging fertilizer. The conveyor belt 21 is mounted on four conveyor belt rollers 24 that are bolted to the support 19. A hydraulic motor 25 is welded to the conveyor belt roller 24 on the right side of the front of the fertilizer applicator 2. The rotating shaft of the conveyor belt 24 is connected to the rotating mechanism of the hydraulic motor 25 to provide power to the conveyor belt 21. The hydraulic motor 25 is connected to the oil tank of an agricultural vehicle such as a tractor through a hose. It is equipped with a gearbox and speed regulator, and the speed of the conveyor belt 21 can be adjusted by adjusting the oil supply. Two pedals 29 are welded to the rear of the fertilizer applicator 2. The pedals 29 are also fixed to the support 19 by bolts through welded steel supports, allowing the operator to easily transport fertilizer via the pedals.

[0035] In addition, when applying organic fertilizers with complex physical properties, such as high humidity, strong viscosity, and easy clumping, problems such as equipment blockage and uneven application may occur. Further improvements can be made to the technical solutions to address these issues.

[0036] The conveyor belt 21 has trapezoidal teeth 23 arranged in a regular pattern on its surface 22, which significantly increases the friction of the conveyor belt and prevents the organic fertilizer from adhering. The fertilizer application device 2 is equipped with a discharge plate 27 and adjusting bolts 28. The discharge plate 27 is a rectangular steel plate, and its size is consistent with the size of the lower front discharge port of the fertilizer box 20, allowing for complete coverage of the lower front discharge port of the fertilizer box 20. Two steel blocks with screw holes are welded to both the discharge plate 27 and the fertilizer box 20. Two movable bolts 18 are inserted into the two steel block groups respectively to fix the discharge plate 27. Simultaneously, the height of the discharge plate 27 can be controlled by rotating the movable bolts 18, thus controlling the usable size of the fertilizer box 20's discharge port. This ensures that the sticky, lumpy organic fertilizer maintains continuous and stable discharge under the action of gravity, conveyor belt friction, and shear force at the discharge port, achieving uniform application and smooth discharge.

[0037] Furthermore, the movable bolt 18 can be replaced with a hydraulic rod to achieve rapid height control of the discharge plate 27. In addition, fixing steel bars 26 are welded to the lower front end of the fertilizer box 20 and the outer side of the discharge plate 27 to further fix the discharge plate 27 in the horizontal direction.

[0038] In addition, it should be noted that the transmission device, hydraulic motor and conveyor belt are all existing technologies. Those skilled in the art can make conventional improvements to the above-mentioned machines, equipment or components under the technical concept of this disclosure, and this disclosure does not impose any restrictions on them.

[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
