Abstract

The utility model relates to a heater unit arranged on an agricultural tricycle or on a quadricycle, which can be used for a one-cylinder motor. The utility model is formed by orderly and hermetically connecting an air intake rubber tube, a supply blower, an air supply hose, a silencing heat exchanger, a heat preservation foaming tube, a warm air tee joint T and a warm air duck bill. The utility model adopts the structure that a circulating tube and cavity are fixed in the original silencer; when the motor works, the heat of end gas is transformed to the wall of the circulating tube and the wall of a cavity in the silencing heat exchanger, and the supply blower sends fresh cold air into the circulating tube and the cavity in the silencing heat exchanger via sealed air supply pipelines; after being heated, the air flows into a steering room through the heat preservation foaming tube.

Description

The agricultural tricycle heater unit

The utility model is the heat energy that utilizes motor exhaust, will be converted to a kind of agricultural tricycle heater unit of warm air by the cold air that supply ventilating fan is sent into by silencer inner circulating tube chamber.

From the kind of existing automobile-used heater unit, mainly based on water heating fan, but it to require driving engine must be multi-cylinder engine, and the agricultural tricycle of single cylinder engine is blank aspect heating always.Though equipment---the warm braw gloves that utilize the silencer heating are arranged in recent years, and its temperature is low, contains poisonous tail gas in the warm braw, thereby can't be used for the heating of closed farm vehicle.Basic reason is its structural shortcoming (structure as shown in Figure 1), and its forming process is: induced draft fan by between induction opening inspiration silencer outer wall and time outer wall, is finished cold air again by pipeline arrival gloves.Because the used silencer of warm braw gloves is to have added one deck shell outside common silencer again, the silencer outer wall is in the low temperature environment, and it has only utilized the heat of silencer time outer wall, and the utilization of tail gas heat quantity is very limited, makes the warm braw temperature that obtains very low.In addition, because fresh air inlet and exhaust port are too near, come air draught by induced draft fan, poisonous tail gas can directly enter the warm braw pipe, and the warm braw that obtains is the mixture of air and poisonous tail gas, and is harmful.Therefore, these warm braw gloves can't be used for the heating of closed car.

The purpose of this utility model provides a kind of heater unit, makes the warm braw temperature height, pure, the nonhazardous of quality that obtain, reaches the heating requirement of closed agricultural tricycle fully; Can satisfy simultaneously the heating requirement of single-cylinder farm four-wheeled, solve the farm vehicle heating problem of single cylinder engine.

The purpose of this utility model is achieved in that this blower structure such as accompanying drawing 2, and this heater unit is connected by silencing heat exchanger and osed top air-supply pipeline and forms.Behind the fresh air process air intake sebific duct, enter silencing heat exchanger by supply ventilating fan by air supply hose and ventilation inlet air-supply, after the engine start, high-temperature tail gas directly is sprayed onto and is fixed on the silencer in-to-in coil pipe outer wall when the silencer, because the coil pipe wall has fully absorbed the heat of tail gas, temperature constantly increases, so, when fresh air is flowed through silencer inside coil pipe, the tube wall very high with temperature carries out thermal energy exchange, obtains very soon heating up.After the intensification, enter operator's compartment through warm braw air outlet and warming foaming pipe again, regulate the warm braw trend by the warm braw threeway: the one, directly blow to operator's compartment; The 2nd, be used for the defrosting of windshield by the warm braw duckbilled.

Owing to adopt such scheme, this heater unit can make full use of the heat of motor exhaust, the temperature that has solved the existence of warm braw gloves is low, contains the problem of poisonous tail gas in the warm braw, and a kind of promptly convenient practical again novel warm-air machine is being provided aspect the heating of single-cylinder farm car.Simultaneously at extremely frigid zones, must put the water in the water tank only behind slow, the engine off owing to exist water heating fan to heat up, otherwise the problem of meeting bursting by freezing water tank, so the utility model heater unit can also replace water heating fan to be applied to the heating of Multi-Cylinder Diesel Engine.

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing 1 is a warm braw glove construction scheme drawing.

Accompanying drawing 2 is structural representations of the present utility model.

Accompanying drawing 3 is major parts of the present utility model---the elevation profile constructional drawing of the embodiment of silencing heat exchanger.

In the accompanying drawing 1,1. induction opening 2. silencer outer walls 3. silencers time outer wall 4. induced draft fans 5. gloves 6. exhaust ports

In the accompanying drawing 2,1. air intake sebific duct 2. supply ventilating fans 3. air supply hoses 4. ventilation inlets 5. silencing heat exchangers 6. warm braws go out 7. thermal insulation foaming pipes, 8. warm braw threeways, 9. warm braw duckbilleds

In the accompanying drawing 3,1. exhaust port 2. warm braw chambeies 3. wind pushing cavities, 4. ventilation inlets 5. circulating pipes 6. warm braws outlet

In accompanying drawing 2, air intake sebific duct (1), supply ventilating fan (2), air supply hose (3), silencing heat exchanger (5), thermal insulation foaming pipe (7), warm braw threeway (8), warm braw duckbilled (9) order sealed attachment constitute a warm braw and form pipeline, during supply ventilating fan work, warm braw enters operator's compartment by this closing pipe line, and warm braw pipeline and exhaust emissions pipeline are not connected.Be to adopt to blow by closing pipe line to finish the warm braw effect by supply ventilating fan.

In accompanying drawing 3, cold air enters in the silencer inner circulating tube chamber by ventilation inlet (4), finishes the conversion of cold air to warm air by the heat of exchange wall of the lumen.In the present embodiment, to adopt the circulating pipe cavity configuration of welded closure in the silencer to be defined as silencing heat exchanger, in accompanying drawing 3, ventilation inlet (4), warm braw outlet (6) and silencer inner circulating tube are formed a closing pipe line, this closing pipe line places in the exhaust emissions chamber, but not connected with the exhaust emissions chamber.In silencing heat exchanger, the circulation tube chamber has absorbed the heat energy of high-temperature tail gas, and when supply ventilating fan was sent into cold air in the inner circulating tube chamber of silencing heat exchanger, cold air can displace the heat of tube wall, thereby finishes the conversion of cold air to hot air.

Claims (3)

1, a kind of heater unit is characterized in that: by air intake sebific duct, supply ventilating fan, air supply hose, silencing heat exchanger, thermal insulation foaming pipe, warm braw threeway, warm braw duckbilled order sealed attachment.

2, heater unit according to claim 1 is characterized in that: in original silencer, and fixed cycles pipe and chamber, promptly the silencing heat exchanger structure adds ripe air.

3, heater unit according to claim 1 is characterized in that: utilize supply ventilating fan to send in the silencing heat exchanger air and operator's compartment by the air-supply pipeline.
