Description

Technical Field

[0001] The utility model relates to the technical field of hole opening devices, in particular to a hole opening device capable of preventing soil splashing. Background Art

[0002] A hole-opening device refers to equipment used to open holes in geological environments such as mud and soil. With the advancement of agricultural mechanization, more and more hole-opening devices are being used in tea planting. These machines can open planting holes efficiently and quickly, and can adjust the depth and size of the holes. The machines currently used in tea gardens are usually improved based on traditional farmland trenchers or drilling machines.

[0003] When drilling holes in harder soil, the existing tea hole-making device will use a water pump to draw water from the water tank and make it fall on the pre-drilled soil through the drainage hole, thereby wetting the soil and reducing the resistance of the hole-making. However, the device does not have a mud retaining structure. During the drilling process of the drill bit, mud will splash on the drainage hole, thereby clogging it and affecting the normal use of the hole-making device. Therefore, it needs to be improved.
