Embodiment Construction

[0038] Such as figure 1 As shown, the present invention comprises power source 9, and power source 9 is connected with drill rod 7 by drill rod thread 8; 5. The dozer screw 3 is set, and the bottom of the drill barrel 4 is connected with the drill bit 1 through the drill bit thread 2. For the convenience of operation, a handle 10 can also be housed on the power source 9 .

[0039] Wherein, the length of the drill barrel 4 is at least 30 cm, which can be 30 cm, 40 cm, 50 cm, 60 cm or even longer, so as to ensure the storage space for the soil volume obtained by the drill bit at a depth of 20 cm. In addition, the length of the drill pipe 7 is at least 50cm, which can be 50cm, 40cm, 50cm, 60cm or even longer, and the number of drill pipes can be increased according to the depth of soil extraction. Each section of drill pipe is threaded to ensure the maximum depth. The soil sampling depth is 2m.

[0040] It should be noted that, driven by the power source 9 and driven by the dr...

Abstract

The invention provides an efficient motorized geotome without moisture loss. The efficient motorized geotome without moisture loss comprises a power source, wherein the power source is connected with a drill rod through drill rod threads; the drill rod is connected with a drill drum through drill drum threads; the drill drum is internally provided with a bulldozing screw rod, and the lower part of the drill drum is connected with a drill head through drill head threads; and the length of the drill drum is at least 30cm, and the length of the drill rod is at least 50cm. By utilizing the technical scheme of the invention, three cutting teeth are uniformly distributed on the drill head, the root parts of the cutting teeth are provided with cutter root circular arcs, thus the flexural strength of the cutting teeth is enhanced, and the service efficiency of the drill head is improved; and based on the design that the cutting face of the drill head is tangential to an inner cylindrical faceand the secondary cutting edge of the drill head is tangential to the cutter root circular arcs and is transitioned to a cutter tip structure through natural circular arcs, the one-time drilling depth of the drill head is ensured to be deeper, and the service efficiency of the drill head is improved.

Description

technical field [0001] The invention relates to a motorized soil drill used for obtaining soil samples in layers efficiently in scientific research on agricultural soil, crops, forestry, agricultural meteorology, agricultural environment and the like. Background technique [0002] There are manual and motorized drills. The manual soil drill is simple in structure, light in weight, and easy to carry, but it is laborious to operate, especially when taking a large number of soil samples, the physical strength consumed is very large. The mobile soil drill is equipped with a power source (electric motor or gasoline engine). Relying on the power of the power source can greatly reduce the physical input of manual operation when taking soil, and the work efficiency is also high. The mobile soil drill is an important direction for the development of soil drilling. [0003] When the soil-borrowing drill takes soil, due to the viscosity of the soil, when the soil-borrowing drill reach...
