Abstract

The utility model discloses a flame weeder which is used for removing the weed in the ends of the fields. The flame weeder is composed by the connection of a pressure container and a flame jet head two big parts, wherein, the flame jet head comprises a protective cover, a preheating pipe, an evaporation pipe, a flame jet pipe, a jet nozzle, etc. The flame weeder has the advantages of simple structure, convenient operation, high weeding speed, good effect and low consumption and simultaneously has no toxicity to human bodies and no harm to crops.

Description

Flame weeder

The utility model relates to a kind of agricultural tool that is used for removing weeds.

For a long time, people have spent all thought to the weeds of removing the field, along with progress of science and technology, though make people broken away from the past merely with hand pull, with the heavy weeding system of hoe shovel, used chemical herbicide.The chemical herbicide price is higher, has surpassed peasant's ability to bear, makes every mu of weeding cost reach 30 yuan; Next is the prescription difference of chemical herbicide, and the kind of weeding is restricted, and often a kind of chemical herbicide can not all be removed all inhomogeneous weeds of field, causes herbicidal effect poor.And chemical herbicide is chemicals, and human body is had certain injury, has carelessness that intoxicating phenomenon will take place slightly when spraying.Simultaneously, use chemical herbicide can make the chemical analysis in the soil higher for a long time, cause the chemical analysis residual quantity of crops to surpass international standard.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of simple in structure, makes easily, and easy to use, herbicidal effect is good, and is nontoxic to human body, the flame weeder harmless to crops.

The purpose of this utility model is to reach by following measure: this flame weeder mainly is with steel pipe and high-pressure hose pressure vessel and firn-jet head two large divisions to be coupled together composition.Wherein firn-jet head is made up of guard shield, economizer bank, evaporation tube, spit tube and nozzle.The lower end and the three-way connection tube of economizer bank join, and the upper end of upper end and evaporation tube joins, and the lower end of evaporation tube and spit tube join.Bocca is placed on the spit tube.

Pressure in the pressure vessel of the present utility model should remain on 0.2-0.3Mpa.

In the economizer bank in the utility model firn-jet head copper rod is housed.

Its profile of evaporation tube in the utility model firn-jet head is shape in the shape of a spiral.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a shape assumption diagram of the present utility model.

Fig. 2 is the structure chart of firn-jet head.

The utility model is described in further detail below in conjunction with embodiment: pressure vessel (1) is to roll with the thin type steel plate to be welded.Be welded with pouring orifice (5), valve (4) and pressure tapping (2) on it, manometer (3) is placed on the joint (2).Pouring orifice (5) is furnished with oiling flap (6).Outlet (12) also is welded on the pressure vessel (1); Fuel adds in the container (1) by pouring orifice (5), and screws oiling flap (6), adds 0.3Mpa air pressure with inflator from valve (4) then, and its air pressure size can be learnt from manometer (3).High-pressure hose (11) couples together the outlet (12) of pressure vessel (1) and the steel pipe (9) on the firn-jet head (10).And be provided with the switch (7) of regulating the oil mass size and the handle of being convenient to operate (8) at the tail end of steel pipe (9).Steel pipe (9) on the firn-jet head (10) and three-way connection tube (14) weld together, and the guard shield (15) that has an air inlet is to be fixed on the three-way connection tube (14) by nut (13).The copper rod (19) that increases pre-heat effect is housed in economizer bank (18) in addition; The lower end of economizer bank (18) and three-way connection tube (14) welding, and the welding of the upper end of the spiral evaporation tube of upper end and profile (17).The lower end of evaporation tube (17) is connected with spit tube (21) by locking nut (20).Nozzle (16) is directly to be fixed on the spit tube (21) by screw thread.After fuel is by economizer bank preheating vaporization, just can go out burning from nozzle by bigger pressure.

The utility model has following advantage compared to existing technology: this flame weeder is simple in structure, easy to use, and not only weeding speed is fast, effective, and it can remove grass-seed and killing ova. Prevent the breeding of weeds and the generation of insect pest. Its weeding expense is low simultaneously, and every mu is only expended 6-10 unit, nontoxic to human body, harmless to crops.

Claims (4)

1, a kind ofly pressure vessel (1) and firn-jet head (10) are coupled together the flame weeder of forming with high-pressure hose (11) and steel pipe (9), it is characterized in that firn-jet head (10) is to be made of guard shield (15), economizer bank (18), evaporation tube (17), spit tube (21) and nozzle (16), the lower end of economizer bank (18) and three-way connection tube (14) join, the upper end joins with the upper end of evaporation tube (17), and the lower end of evaporation tube (17) and spit tube (21) join, and nozzle (16) is placed on the spit tube (21).

2, flame weeder according to claim 1 is characterized in that the pressure in the pressure vessel (1) should remain on 0.2-0.3Mpa.

3, flame weeder according to claim 1 and 2 is characterized in that being equipped with in the firn-jet head (18) copper rod (19).

4, flame weeder according to claim 3 is characterized in that its profile of evaporation tube (17) shape in the shape of a spiral in the firn-jet head (10).
