  However, in the tilling clay machine described in Patent Document 1, the burner 88 is installed toward the rear side of the tilling blade 83, so it is not stationary while being plowed by the tilling blade 83. A flame will be radiated to the soil, and there is a problem that the soil is not sufficiently heated and the control efficiency is poor.

  In addition, the control by the flame is particularly effective for pests existing on the surface of the field, and the pests are higher as they are closer to the surface of the field. However, in the plowing and clay machine described in Patent Document 1, since it is plowed with the plowing blade 83 just before the control with the flame, the heat of the flame removes many pests that exist near the surface of the field. There is a problem that the control efficiency is lowered because it is hidden in the soil that is difficult to transmit.

  And the flame weeding apparatus 90 described in Patent Document 2 has the above-described problems as well as the tilling and clay machine described in Patent Document 1.

In order to solve the above problems, the flame control machine of the present invention is

The plowing means is arranged at a distance from the burner in the forward direction of the aircraft.

  According to this configuration, since the tillage means is disposed at a distance from the burner in the forward direction of the machine body, after plowing, it is possible to radiate a flame to the soil that is stationary on the field surface. The soil can be sufficiently heated, and the control efficiency can be improved.

  In the flame type control machine, the tilling means is provided so as to be able to move up and down between a plowed state lowered so as to plow the field and a retreated state raised so as not to plow the field.

  According to this configuration, since the tillage means is provided so as to be able to move up and down, it can be appropriately controlled without plowing or after plowing. For example, the field surface that is not cultivated is controlled with a flame by putting the tillage means in the retracted state during the first control, and the tillage is put in the tillage state during the second control. The field surface can be controlled with a flame. This ensures that the field surface with a high pest presence rate is controlled during the first control, and the remaining pests lurking in the soil during the second control are plowed. It can be controlled by moving it to the vicinity.

  In the flame type pest control machine, an example in which the second burner disposed in the forward direction of the machine body in the tillage means is illustrated.

  According to this configuration, first, the field surface that is not cultivated is controlled by the flame of the second burner, the field after the control is cultivated by the cultivating means, and the field surface that has been cultivated is It can be controlled with the flame of the burner. Thereby, by the one control work, the second burner reliably controls the field surface having a high presence rate of pests, and the remaining pests lurking in the soil of the field are removed by the tillage means. It can be moved to the surface and controlled by the burner, and work efficiency can be improved.

Next, as shown by the solid line in the figure, the burner 5 is placed in the control state SBa, and the operator holds the hand-held handle 14 and walks the flame-type control machine 1 forward to the front of the machine. The entire surface of the field H that has not been used is controlled by flame. Next, as shown in FIG. 1, the tilling blade 6 is brought into the tilled state SCa, and the operator holds the hand-held handle 14 and walks the flame type control machine 1 forward of the machine body. While cultivating H with the cultivating blade 6, the surface of the cultivated field H is controlled with a flame.

  According to the flame type control machine 1 of the present example configured as described above, the plurality of tilling blades 6 are arranged at intervals in the forward direction of the machine body from the burner 5. A flame can be radiated to the soil stationary on the surface, heat can be sufficiently transmitted to the soil, and the control efficiency can be improved.

  Moreover, since the tilling blade 6 as a tilling means is provided so that raising and lowering is possible, the field H can be properly controlled without being plowed or controlled after being plowed. For this reason, as described above, when the plowing blade 6 is placed in the retracted state SCb during the first pest control, the non-plowed field surface is controlled with flame, and during the second plow control, the plow blade 6 is plowed. By making the state SCa, the cultivated field surface can be controlled with a flame. As a result, the surface of the field with a high pest presence rate is reliably controlled during the first control, and the remaining pests lurking in the soil of the field H during the second control are subsequently plowed. It can be controlled by moving it to the vicinity of the surface.
