Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a heater for drying leaf tobacco which blows warm air into the leaf tobacco drying house, and particularly to a leaf tobacco drying house to which commercial power is not supplied. The present invention relates to a heater for drying leaf tobacco, which is preferably used in.

[Prior Art] Leaf tobacco harvested in the field is shipped in a dry and weight-reduced state.

In order to dry the leaf tobacco as described above, the leaf tobacco is generally hung in a vinyl house or the like, and hot air is blown into the house to keep the leaf tobacco at a high temperature.

This type of drying heater is proposed in Japanese Utility Model Laid-Open No. 60-65595.

The drying heater proposed in Japanese Utility Model Laid-Open No. 60-65595 has an outside air introducing pipe at one end of a combustion instrument and a hot air supplying pipe for supplying hot air at the other end, and the outside air introducing pipe passes through a heat exchanger. Then, a fan for sending air to the hot air supply pipe is provided on the upper part of the combustion appliance.

A gas burner is used as a heat source.

[Problems to be Solved by the Invention] The above drying heater requires a fan for supplying hot air, and when kerosene or the like is used as fuel, the flame is generated at the initial stage of ignition until the burner crater becomes red-hot. A glow plug is needed to keep the Conventionally, a commercial power source has been used because the electric power required for such a fan and an ignition glow plug is considerably large.

On the other hand, since the leaf tobacco before drying is heavy, it is advantageous to dry it near the harvested field for transportation, and a dry house is often constructed in the field, and commercial power cannot be obtained in some cases.

When there is no commercial power source, a generator is used.However, such a generator is expensive and heavy, which causes problems such as troublesome transportation.It is not used sufficiently and the leaf tobacco is dried naturally. And was a cause of quality deterioration.

The present invention was made to solve the above problems,
It is an object of the present invention to provide a heater for drying leaf tobacco which can use inexpensive kerosene as a fuel and does not require a commercial power source or a generator.

Another object of the present invention is to provide a heater for drying tobacco, which can be transported by using a tractor, can be easily attached and detached, and has a heater stand.

[Means for Solving the Problems] A heater for drying leaf tobacco according to the present invention is a heater for drying leaf tobacco in which air heated by the heat of combustion of fuel is blown into a greenhouse for drying tobacco leaf to ignite a fuel combustion burner. The battery of the tractor is used as a power source for the glow plug and the fan for blowing warm air, and a fixture for the three-point support device of the tractor is provided.

[Operation] The heater for drying tobacco of the present invention can be easily transported to the greenhouse for drying tobacco by the tractor by attaching it to the three-point supporting device of the tractor through the fixture provided on the heater for drying. Since the power source of the tractor used for transportation is used, no commercial power source or generator is required.

Therefore, it is possible to improve the quality by connecting the leaf tobacco drying house near the field to reduce the transportation cost and easily obtaining the temperature required for the leaf tobacco drying.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 1 is a view showing a heater for drying leaf tobacco which is an embodiment of the present invention. In the figure, reference numeral 1 is the heater body, and the front leg
Being independent, supported by 8,8 and rear legs 7,7.

A fuel tank 3 is fixed to the side surface of the heater body 1.

An air inlet cover 4 covers the air intake port provided in the heater body 1 with a dustproof net.

Reference numeral 5 denotes a hot air supply pipe, to which a vinyl duct 11 extending into the house is connected.

Reference numeral 10 denotes an exhaust pipe from which burned exhaust gas is released, which can be removed.

Inside the heater body 1, there is arranged a fan for blowing hot air, which sends air taken in through the air inlet cover 4 so as to be discharged from the hot air supply pipe 5 via a heat exchanger.

Heat generated by burning kerosene stored in the fuel tank 3 with a burner is supplied to the heat exchanger, and combustion gas is discharged from the exhaust pipe 10.

At the crater of the kerosene burner, a glow plug for igniting a nichrome wire is provided.

The heat exchanger and the kerosene burner are well known and can be appropriately designed, and their structures are not shown.

The power source of the fan for hot air blowing, the glow plug for ignition, and the fuel pump for supplying kerosene is DC 12V, which is supplied by a cable extending from the control panel 2.
Further, on / off control is performed by switches in the control panel 2.

Pins 9 are attached to the legs 7 and 8 arranged on one side of the heater body,
9 is erected, and brackets 6 and 6 are fixed to face one side of the upper part of the heater body.

The pins 9 and 9 and the brackets 6 and 6 can be engaged with the left and right lower links and the upper link of the three-point support device of the tractor shown in FIG. 2, respectively, and form a fixture for the tractor.

In the above structure, the heater for drying tobacco is attached to the rear part of the tractor via the hydraulically operated three-point support device held by the tractor with the exhaust pipe 10 removed, and is transported to the tobacco drying house.

Then, the heater main body carried in the mounted state on the tractor is set outside the house, and the duct 11 extending into the house is connected to the warm air supply pipe 5. Further, the exhaust pipe 10 is attached to the exhaust port, and the battery of the tractor is connected to the terminal of the control panel 2.

Then, a fan for supplying warm air and a fuel pump for supplying kerosene are started, and a burner is ignited by an ignition glow plug to blow warm air into the house through a large number of small holes provided in the duct 11.

The air temperature in the house rises and the tobacco can be dried in a short time.

The glow plug for ignition is turned off after the burner is heated until the flame is retained, but the fan for hot air blowing and the fuel pump are operated while the heater for drying is used and used for a long time. If so, it is desirable to rotate the tractor engine to protect the battery.

The embodiment of the present invention is configured as described above, but the present invention is not limited to this. For example, the heater main body is arranged inside the house, and the exhaust pipe is extended to the outside of the house so that the exhaust gas is discharged to the outside of the house. It is also possible to supply air from inside the house.

[Effect of the Invention] As described above, the heater for drying leaf tobacco of the present invention is transported by using a tractor widely used by farmers.
Also, since it does not require commercial power, it can be conveniently used in a dry house set up in a field.

The dimensions of the three-point support device for the tractor are specified in JIS, and it is not necessary to change the fixture even if the tractor model is different.

The heater for drying leaf tobacco according to the present invention can be used for drying shiitake mushrooms and the like, and can also be used for heating during agricultural work.
Even in that case, the above-mentioned effects are obtained.
