Description

Technical Field

[0001] The utility model relates to the technical field of crop planting, in particular to a portable farmland drilling device. Background Art

[0002] Hole sowing is an important task in agricultural production. For crops such as corn, cotton, beets, sunflowers and beans, the production requires that the seeds be sown in holes according to a certain row spacing and hole spacing. Traditional crop planting drilling basically relies on manual digging of holes. This method is inefficient and increases the labor intensity of workers. It is not conducive to controlling the depth, row spacing and hole spacing of the holes. The holes dug are arranged in a messy manner, which is not conducive to crop sowing and seed survival.

[0003] In order to solve the above technical problems, the technical solution of the Chinese utility model patent announcement with patent application number CN202020678567.5 is a drilling device for vegetable planting, comprising a supporting foot, two supporting feet are provided, and a movable wheel is provided at the bottom of the supporting foot, a rotating shaft is provided on the opposite side of the two supporting feet, and the rotating shaft is rotatably connected to the supporting foot through a bearing, a connecting plate is fixedly connected to one side of the rotating shaft, a push handle is provided on the side of the connecting plate away from the rotating shaft, connecting columns are provided on both sides of the bottom of the connecting plate away from the rotating shaft, a fixing rod is provided at the bottom of the connecting column, and mounting holes distributed at equal intervals are provided at the bottom of the fixing rod, and the size of the mounting hole is consistent with the size of the top of the drilling bit. , and one side of the fixing rod is provided with a through hole distributed one-to-one with the mounting hole, the through hole is connected to the mounting hole, and one side of the top of the drilling drill bit is provided with a first threaded hole, the first threaded hole and the through hole are located at the same horizontal height, and the drilling drill bit is fixedly connected to the fixing rod by a bolt. According to the utility model, the push handle is pushed by hand, and the device is moved under the action of the moving wheel. When drilling a hole is needed, the handle of the push handle is pressed downward by hand. Since the connecting plate rotates through the rotating shaft and the supporting foot, the connecting plate moves downward close to the push handle. Therefore, under the action of the lever principle, the drilling drill bit contacts the ground to drill a hole. Since the lever principle has a labor-saving effect, the labor intensity of the user is reduced.

[0004] However, the above-mentioned prior art has the following technical problems: the punching device for vegetable planting provided by the above-mentioned scheme arranges the punching drill bits at equal intervals at the bottom of the fixed rod to make the hole distances the same when punching. However, the optimal hole distances when planting different crops are also different. Too large or too small hole distances will affect the crop yield. Therefore, when actually drilling holes, not only must the hole distances be kept the same, but the hole distances must also be adjusted according to the types of crops to ensure the crop yield.
