Abstract

The utility model discloses a low temperature start heater for a tractor, which is used on a baby tractor or the diesel engine of an agricultural tricycle. The utility model is composed of electric heating tubes, a heat transferring disk, a heat conducting plate, etc. An outer casing 1 and the bottom of one side of the heat conducting plate 4 constitute a hollow cavity. A cast-iron heat transferring disk 3 which is sealed is arranged in the hollow cavity. At least one U-shaped electric heating tubes 2 are cast in the heat transferring disk 3. The heat transferring disk 3 is fixed on the bottom of the heat conducting plate 4. The heat conducting plate 4 is tightly fixed between the cylinder end 9 of an engine and an air inlet tube 8. The heat conducting plate which is arranged at the center position of the air inlet passage of the air inlet tube 8 and the cylinder end 9 has four vent holes 13. The utility model has the advantages of compact structure, no naked fire, fast temperature rising, high efficiency, convenient and safe installation and convenient and safe use.

Description

Low temp. start heater for tractor

The utility model relates to the starting aid of internal-combustion engine; Particularly relate to the cold-starting heater that is used for microtractor or agricultural tricycle.

Have the diesel engine of microtractor or agricultural tricycle now, have the problem of cold-starting difficulty at large.Usually, how roasting with fire people's, methods such as hot water scalds, ignition paper heat.But these methods not only waste time and energy, and also exist great unsafe factor.The someone adopted commercially available electric furnace or with the drain pan of high-power bulb baking diesel engine in recent years, but the thermal efficiency is all very low, general all below 20%, and electric furnace toasts because of its resistance wire surface conductance and has naked light, so danger is also very big, the bulb baking then heats up slowly, efficient is low, needs sometimes to toast a few hours, so also inconvenience is promoted.

The purpose of this utility model is at above-mentioned difficulty and problem, provides a kind of without naked light baking, and quick heating, efficient height, safe and reliable, is specially adapted to the cold-starting heater of microtractor or agricultural tricycle diesel engine.

Basic fundamental solution of the present utility model is, heat conduction board of device between the cylinder head of motor and suction tude is equipped with electric heating tube and heat transfer dish on the heat conduction board.After the energising, electric heating tube is through the heat transfer of heat transfer dish and heat conduction board, and the cylinder head heating with motor realizes the smooth starting under the low temperature.

Fig. 1 is the front view of the utility model package assembly; Shown in the figure embodiment who is applicable to 195 types series diesel engine cold-starting heater.

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is a plan view of the present utility model;

Fig. 4 is the heat insulating washer plan view that the utility model is selected for use.

Specific embodiments of the present utility model can be described as follows referring to figs. 1 through Fig. 4:

1,, forms a cavity with it by shell 1, cast iron heat transfer dish 3 of encapsulation in the cavity in the bottom of heat conduction board 4 one sides;

2, the inside of heat transfer dish 3 is cast with a U type electrothermal tube 2 at least;

3, the resistance wire Outlet of electric heating tube 2 is cascaded with socket 6 on the shell 1;

4, the heat transfer dish 3 in the cavity is packed in the bottom of heat conduction board 4 by screw 7;

5, the opposite side of heat conduction board 4 has two mounting holes 12, by the original bolt 11 of diesel engine it is fastened between engine cylinder head 9 and the suction tude 8;

6, be positioned at the gas-entered passageway central position of suction tude 8 and cylinder head 9 at heat conduction board 4, four vents 13 are arranged.

7, between heat conduction board 4 and the suction tude 8, be lined with asbestos slate heat insulating washer 5 shown in Figure 4.

Working principle of the present utility model is as follows: after the energising, the heat that electric heating tube 2 sends passes feeding diesel engine cylinder head 9 through heat transfer dish 3 and heat conduction board 4, with the motor heating, makes its smooth starting at low temperatures after several minutes.

The utility model compact structure, the flames of anger, quick heating, efficient height, easy to install and use, safe and reliable.
