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.

Embodiment 1

[0028] The light-duty agricultural earth-boring machine disclosed in this embodiment is composed of two parts: a host machine and a drilling tool that cooperate with each other;

[0029] Among them, see figure 1 , 2 As shown, the drilling tool includes a drill bit 1 and a drill rod 2 that can be combined and connected. There are multiple drill rods 2 that can be connected end to end; The sheet 201 is wound and fixed on the outside of the core rod 202; the helical sheet 201 is surrounded by a number of axial grooves 5 that are equiangularly distributed and extend axially along the drill pipe 2, and the outer edge of the helical sheet 201 is in the adjacent axial groove. The part between 5 is tooth 3;

[0030] Among them, see image 3 , 4 , 5 and 6, the main frame includes a frame 8, the frame 8 is provided with a top plate 14 and a base plate 9 distributed up and down, and the frame 8 is laid flat on the ground and the base plate 9 has a ground clearance. The top plate 14 ...

Embodiment 2

[0051] see Image 6 As shown, during the drilling operation of the light-duty agricultural earth-boring machine disclosed in the aforementioned embodiments, the spiral piece 201 will transport the earth material produced in the borehole to the ground. Generally, it will not affect the normal operation of the drilling operation. If the drilling depth is deep and the soil material produced is large, the soil material needs to be transferred to avoid the soil material gathering above the hole and affecting the drilling efficiency. The operator can The soil material produced by drilling is transferred by tools such as shovels to avoid the accumulation of soil material above the hole, but this operation method is cumbersome, time-consuming and laborious. For this reason, the present embodiment has further improvements on the basis of the structure of the light agricultural earth-boring machine disclosed in embodiment 1, and the specific structure is:

[0052] see Figure 9 , 10 ...

Embodiment 3

[0056] see Image 6 As shown, in the structure adopted by the light-duty agricultural earth-boring machine disclosed in the foregoing embodiments, the helical piece 201 is provided with an axial groove 5 so that its outer end is formed with teeth 3 distributed at intervals. This kind of special structure will weaken its upward conveying ability to soil materials, but because most of the soil in the farmland has poor fluidity, in addition, the rotation frame 13, driving roller 12, axial groove 5, teeth 3 and other parts can be adjusted during implementation. Relative positional relationship, quantity, specific shape and size and other parameters are reasonably adjusted to make up for the aforementioned lack of poor conveying capacity, thereby ensuring that the spiral blade 201 can convey the soil material generated during the drilling process to the ground above the ground. At the same time, this embodiment has a further improvement on the basis of the structure of the light-du...

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...
