Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to an oil-using peony fertilizing device. Background Art

[0002] During the fertilization process of oil peony, the appropriate type of organic fertilizer is selected according to the crop type and soil conditions before fertilization. However, there are the following problems when fertilizing oil peony. First, when fertilizing oil peony, the width and depth of the groove are large, the number of grooves is large, and the amount of excavation is large. Second, the amount of fertilizer is large. Third, the soil hardness around the oil peony is large. Fourth, when fertilizing oil peony, due to the limitations of terrain and space for oil peony, large-scale machinery cannot be used for construction, and generally only manual excavation can be used. Fifth, when fertilizing, there are many steps, which are divided into multiple links such as trenching, fertilizing, and covering soil. Due to the above problems, the workload is greatly increased when fertilizing, and the efficiency of fertilization is low. Summary of the invention

[0005] A middle groove is provided in the middle of the trolley, and two symmetrical guide rods are provided on both sides of the middle groove, one of the guide rods is provided with a screw hole on one side, the guide holes on both sides of the lifting seat are slidably connected to the two guide rods, the screw holes are rotatably connected to the screw screws, and the screw screws are threadedly connected to the screw holes on one side of the lifting seat.

[0006] The universal joint includes a No. 1 swivel seat and a No. 2 swivel seat which are hinged to each other. The No. 1 swivel seat and the No. 2 swivel seat are of C-shaped structure. A No. 1 swivel seat middle hole and a No. 2 swivel seat middle hole are respectively arranged in the middle of the No. 1 swivel seat and the No. 2 swivel seat, and a No. 1 swivel seat side hole and a No. 2 swivel seat side hole are respectively arranged on the sides of the No. 1 swivel seat and the No. 2 swivel seat, a No. 1 bevel gear is rotatably connected in the side hole of the No. 1 swivel seat and a No. 2 bevel gear is rotatably connected in the middle hole of the No. 1 swivel seat of the No. 1 swivel seat, and a No. 3 bevel gear is rotatably connected in the middle hole of the No. 2 swivel seat of the No. 2 swivel seat, and the No. 1 bevel gear is meshed with the No. 2 bevel gear and the No. 3 bevel gear on both sides at the same time.

[0007] The universal joint at the bottom of the ground loosening device is called the first universal joint, and the universal joint at the top of the ground loosening device is called the second universal joint, wherein the side surface of the No. 1 swivel seat of the second universal joint is provided with a turbine coaxial with the side hole of the No. 1 swivel seat, and the side surface of the No. 2 swivel seat of the second universal joint is provided with a worm seat, a worm is rotatably connected in the worm seat, the worm and the turbine are meshed with each other, one side of the worm intermediate shaft is connected to the No. 3 motor, and the No. 3 motor is fixed on the side surface of the No. 2 swivel seat.

The front side of the No. 1 swivel seat of each first universal joint is fixedly connected to a side plow, and the width of the side plow is greater than the width of the first universal joint.

[0009] Beneficial effect: The lifting seat and the lead screw cooperate with each other to adjust the depth of the groove. The width of the side plows on both sides is greater than the width of the first universal joint, so that the first universal joint can penetrate into the soil without resistance. The rotating No. 3 screw shaft cuts narrow grooves on both sides of the groove. The rotating No. 2 screw shaft can easily loosen the hard soil layer, reduce the resistance during trench digging, prevent the soil from being too hard, and prevent the plow from being unable to dig when the trench size is too large, thereby improving the efficiency of trench digging and ensuring the size of the trench, so that the plow can dig trenches more easily. There is no resistance when the plow moves forward in the soil loosened by the No. 2 spiral shaft. The soil slides from the surface of the plow to the upper part of the plow, and a groove is formed at the lower part of the plow. Fertilizer is placed in the hopper. When the No. 1 motor rotates, it drives the No. 1 spiral shaft to rotate, and the No. 1 spiral shaft sends the fertilizer to the fertilizer brushing plate at the lower part. The fertilizer brushing plate throws the fertilizer away, and the fertilizer falls into the groove at the lower part of the plow. After the fertilizer is filled in the groove, the soil slides from the back side of the plow, and the soil covers the fertilizer. The above makes loosening the soil, digging trenches, fertilizing, and covering the soil integrated, and the work efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS
