Light agricultural earth boring machine

Abstract

The invention relates to the field of agricultural machines and tools, and particularly discloses a light agricultural earth boring machine. The light agricultural earth boring machine comprises a main machine and a boring tool; the boring tool comprises a boring rod and a boring bit, a spiral piece is arranged on the boring rod, axial grooves are formed in the periphery of the spiral piece, and teeth are arranged on the portion, between the adjacent axial grooves, of the outer edge of the spiral piece; a top plate and a bottom plate are arranged on a rack of the main machine, a main shaft and at least three reversing frames are rotationally fixed between the top plate and the bottom plate, at least three roll shafts are arranged on each reversing frame, and the reversing frames are jointly in transmission connection with the main shaft; each roller shaft is sleeved with a stirring roller, and a motor is arranged in the rack; after the boring tool is combined with the main machine, when the reversing frames rotate synchronously, the stirring rollers on the reversing frames circularly stir the teeth so as to jointly drive the boring rod to rotate. The light agricultural earth boring machine is scientific and reasonable in structural design, high in utilization rate of mechanical parts, small in energy loss, convenient and fast to use, efficient and labor-saving in operation, large in boring depth range, high in practicability, and wide in application prospects in agricultural production.

Description

technical field [0001] The invention relates to an agricultural implement, in particular to a light earth drilling machine suitable for drilling soil in agricultural production. Background technique [0002] Agricultural soil drilling machine is a kind of mechanical equipment commonly used in agricultural production process. It can drill holes in the soil efficiently and quickly, and then in the process of planting crop seedlings, fertilizing deep forest trees, buried piles in greenhouse or fence construction, etc. It is widely used. The currently commonly used small agricultural earth drilling machines are usually of a walk-behind design, consisting of a drill pipe with helical fins and a main engine with power. The main engine usually uses an electric motor or a fuel engine as a power source. There are some deficiencies in the actual application of the existing small-scale agricultural earth-boring machine with the above-mentioned structure. First, it is necessary to manua...

Problems solved by technology

There are some deficiencies in the actual application of the existing small-scale agricultural earth-boring machine with the above-mentioned structure. First, it is necessary to manually erect the equipment on the ground before the drilling operation starts, and lift the relatively cumbersome main engine to a high position to drill the hole. During the operation, the main machine needs to be manually supported. After the drilling is completed, the entire equipment needs to be lifted to remove the drill pipe from the hole. The entire operation process is laborious and often cannot be operated by a single person; The operator controls the main engine by hand, and the drilling direction is difficult to accurately control and cannot be kept constant. The resulting drill hole diameter and hole direction are not standardized, which often has an adverse effect on subsequent operations; third, the existing small agricultural drills Based on its hand-held structural design characteristics, the drill pipe should not be too long, otherwise it cannot be used hand-held, resulting in a small maximum drilling depth, which greatly reduces its practicability and greatly reduces its use in agricultural production operations.
