Background

In conventional farming, the soil structure in the field can slowly change to form a plough bottom layer due to the fact that long-term farming is often subjected to multiple times of squeezing of the soil by agricultural implements and accompanied by deposition of slime in the process of precipitation. The consistency of the plough bottom layer is larger, the total porosity is small, runoff, poor water permeability, poor air permeability, difficult root system lower edge and other adverse phenomena can be caused, and the material transfer, energy transfer and root system downward extension in soil are seriously hindered. Therefore, manual measures are needed to deeply loosen the plough so as to achieve the purpose of reforming or eliminating the plough bottom layer.

With the vigorous development of mechanized soil deep scarification technology in recent years, a deep scarification machine plays an important role in agricultural production, the deep scarification technology is the most effective method for breaking a plough bottom layer, soil is not turned over while a plough layer is deepened, the soil becomes loose, the soil quality is effectively improved, and the soil water storage and soil moisture preservation capability is improved.

The existing subsoiler generally has the problem of large operation resistance, and under the condition that the horsepower of a matched tractor is certain, the tillage resistance of the subsoiler in the soil operation is reduced as much as possible, the operation is convenient, and the operation efficiency is improved. At present, a vibration drag reduction method is a common method for deep scarification drag reduction. Although the vibration subsoiler reduces the working resistance, there are some problems such as impact compaction on the broken soil, uneven bottom of the subsoiling trench after operation, and fatigue damage of the subsoiler and other parts due to vibration, which affects the service life of the subsoiler and reduces the reliability of the operation of the subsoiler.

The air heater 5 is fixedly arranged on the hot air rack 3 through bolt connection, and the subsoiler 1 is fixedly connected below the subsoiler 2 through a welding mode. The subsoiler 1 is a hollow structure, and the surface of the head 11 of the subsoiler 1 is provided with hot air holes 112. One end of the hot air pipe 4 is connected with the hot air blower 5, the other end of the hot air pipe is connected with the subsoiler 1, and hot air generated by the hot air blower 5 is discharged from a hot air hole 112 on the shovel head 11 of the subsoiler 1 through the hot air pipe 4.

The subsoiler head 11 and the shaft 12 of this embodiment are both hollow. Referring to fig. 3, which is a schematic view of the structure of the blade head of the subsoiler, the blade head 11 of the subsoiler 1 of this embodiment has hot air holes 112 uniformly distributed on the soil-facing surface, and the diameter of the hot air holes 112 is 1mm to prevent the hot air holes 112 from being blocked during operation, so as to discharge hot air. The head of shovel head 11 is provided with pipeline port five 111 of 10mm, and pipeline port five 111 is used for installing hot blast pipe 4.

Referring to fig. 4 and 5, there are shown front and top views of the shank of the subsoiler. The head and the tail of the shovel handle 12 are respectively provided with a pipeline port three 122 and a pipeline port four 121 which are 10mm, and the shovel head 11 and the shovel handle 12 are connected together by welding so as to be convenient for installing the hot blast pipe. The pipe port four 121 at the tail of the shovel shaft 12 is matched with the pipe port five 111 at the head of the shovel head 11.

Referring to fig. 6, 7 and 8, which are a bottom view, a front view and a top view of the subsoiler frame assembly, respectively, a first pipe 212 and a second pipe 211 are disposed above and below the subsoiler frame 2, respectively, the first pipe 212 and the second pipe 211 are in the same vertical line, and the third pipe 122 is engaged with the second pipe 211, and when the subsoiler 1 is mounted on the subsoiler frame 2, the third pipe 122 at the head of the subsoiler is aligned with the second pipe 211 on the subsoiler frame 2.

Referring to fig. 9, a sectional view of the hot blast pipe installed inside the subsoiler and the subsoiler frame is shown. The hot air pipe 4 passes through a first pipeline port 212 and a second pipeline port 211 of the subsoiler frame 2, then passes through a third pipeline port 122 and a fourth pipeline port 121 of a shovel handle 12 of the subsoiler 1, and then passes through a fifth pipeline port of a shovel head 11 of the subsoiler 1, and finally the hot air fan 5 discharges hot air to the hollow shovel head 11 and then to the outer side of the shovel head 11 through a hot air hole 112 of the shovel head 11.

Referring to FIG. 10, a schematic view of the handle portion of the present invention is shown with the four subsoilers removed. The hot air generated by the hot air blower 5 is directly conveyed to the shovel head through the hot air pipe 4, the diameter of the hot air pipe 4 is small, so that the heat loss is small in the conveying process, and the hot air output from the tail end of the hot air pipe 4 is discharged from the hot air hole 112 of the shovel head 11. In the subsoiling process, because the water content of deep soil is high, the hot air fan 5 outputs hot air from the hot air hole 112 of the shovel head 11 through the hot air pipe 4, and the diameter of the hot air pipe 4 is small, so that the hot air output from the hot air hole 112 has certain pressure, a thin air film is formed on the surface of the shovel head 11, the soil can slide on the surface of the subsoiling shovel 1, and the sliding resistance of the soil to the subsoiling shovel is reduced. In addition, because the hot air can dry the soil around the surface of the shovel head 11, the dry soil can reduce the viscous resistance to the shovel head 11, and the effects of reducing resistance and debonding are also achieved. The design and the working principle finally achieve the purpose of hot air resistance reduction of the subsoiler.

The working principle is as follows: the hot air blower 5 is connected with the hot air pipe 4, introduces the generated hot air into the hot air pipe 4, sequentially passes through the first pipeline port 212 and the second pipeline port 211 of the subsoiler 1, the third pipeline port 122 and the fourth pipeline port 121 of the handle part of the subsoiler along the hot air pipe 4, and then passes through the fifth pipeline port 111 of the shovel head 11 part of the subsoiler 1. Finally, the hot air blower 5 discharges hot air into the hollow shovel head 11, and then discharges the hot air out of the shovel head through the hot air holes 112 of the shovel head 11, so as to achieve the effects of drying soil around the surface of the shovel head 11 and reducing drag and debonding. For the direct landing from shovel head 11 of broken soil, can not produce the compaction for the ditch bottom unevenness is loosened to the dark after the operation, and the subsoiler does not have the vibration, for vibration damage life, this embodiment does not have this problem, the reliability increase of subsoiler operation.

In this embodiment, the hot air duct 4 is relatively long and directly supplies hot air to the blade head 11 of the subsoiler 1. As can be known by persons skilled in the art, the handle 12 of the subsoiler 1 is of a hollow structure, the hot air pipe 4 can directly convey hot air to the head of the handle 12 of the subsoiler 1, the hot air flows into the shovel head 11 in the handle 12, and the handle 12 can be heated by the hot air, so that soil on the handle 12 can fall off.
