Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural trench-digging equipment, and particularly relates to a trench-digging and shaping machine. Background Art

[0002] Agricultural machinery refers to various machines used in the processes of crop planting and animal husbandry, as well as in the primary processing and treatment of agricultural and livestock products. The trench-digging device is a commonly used agricultural machine and is an essential tool for trench-digging, fertilizing, draining, planting, and irrigating in orchards, vegetable gardens, and other farmland environments. However, during the use of existing trench-digging devices, since most of them do not have the function of trench trimming, after the trench-digging is completed, the overall aesthetics of the trench is poor. At the same time, the soil on both sides of the upper opening of the trench is very easy to flow back into the trench again, which affects the overall trench-digging effect. Therefore, to solve the above problems, it is necessary to develop a trench-digging and shaping machine with diverse functions and good use effects. Content of the Utility Model

The outer ends of the output shafts are concentrically and fixedly connected with cutter discs, and the inner ends are located inside the box body and are concentrically and fixedly connected with bevel gears d. The bevel gear d meshes with the bevel gear c on its same side.

[0006] The ditch repair and shaping component is located outside the ditch cleaning plow shovel. It includes an intermediate connecting shaft, a power box, and a telescopic oil cylinder. The intermediate connecting shaft longitudinally rotates and penetrates through the upper end of the U-shaped mounting frame.

The rotation of the sprocket a311 can drive the intermediate shaft 31 and the sprocket b312 to rotate. The rotation of the sprocket b312 can drive the sprocket c352 and the rotating shaft 351 to rotate by the second chain. The rotation of the rotating shaft 351 can drive the ditch repairing cone disks 36 and the forming pipes 39 at both ends of it to rotate. Thus far, the rotation of the ditch repairing cone disks 36 can level the inner wall of the groove, thereby improving the beauty of the groove. The rotation of the forming pipes 39 can compact the loose soil on both sides of the upper opening of the groove, thereby avoiding the problem that the overall ditching effect of the utility model is affected because the soil flows back into the groove again.Moreover, the utility model is provided with an inclined tie rod 34, a telescopic oil cylinder 33, a bracket a 37 and a bracket b 38.
