Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a liquid sprinkling device that enables a control work and a sprinkling work to be efficiently performed using a single liquid spraying machine.

Conventional technology and problems to be solved In most conventional boom sprayers, a long boom with a large number of nozzles on the left and right sides of the machine body is extended horizontally. Since it is sprayed from above, it is impossible to evenly attach the chemical solution to the foliage of the crop, and it is practically impossible to spray it on the back side of the leaf, which has a particularly high control effect. Therefore, a pest control machine is also proposed, in which a comb-tooth-shaped jet tube body is provided for hanging and spraying the spray tube body between crop rows, and the chemical solution is sprayed from the side of the crop stem by the comb-tooth-shaped jet tube body. However, when performing sprinkling work using a comb-shaped jet tube, the number of nozzles is large compared to the length of the lateral support member, and the nozzles are facing sideways, There was a problem such as not being able to spray water efficiently.

Means for Solving the Problems Therefore, according to the present invention, in a machine in which a liquid spreader having a jet tube body is detachably mounted on a traveling machine body, a length along a stem-culm direction of a crop stem is set to the liquid spreader. A comb-shaped jet tube body in which a large number of shaku jet tubes are vertically provided on a lateral support member and a horizontal jet tube body in which a plurality of jet nozzles are horizontally arranged in a state of being close to the lateral support member are detachably provided. The above-mentioned problems are solved by mounting the comb-shaped jet tube body and the horizontal jet tube body on the liquid spraying machine in a replaceable manner.

Action When carrying out control work, attach a comb-shaped jet tube to the liquid sprayer and spray the chemical liquid from the side of the crop stem. Also,
In the case of water sprinkling work, a horizontal spray pipe is attached to the liquid sprayer and water is sprinkled from above toward the ground.

By the way, according to the present invention, in the liquid spraying machine 1, a comb-shaped jet pipe body 15 in which a large number of long jet pipes 15a along the stem-culm direction of the crop stems are vertically provided on the lateral-direction support member 15b, and the lateral-direction support member. Horizontal jet nozzles 16 each having a large number of jet nozzles 16c arranged horizontally in a state of being close to 16b are detachably provided, and these comb-shaped jet nozzles 15 and horizontal jet nozzles 16 are liquid. It is replaceably attached to the spreader 1. That is, the stays 17 and 17a are horizontally mounted on the rear surface of the machine frame 1a through the U bolts U so that the stays 17 and 17a can be adjusted vertically.
An injection pipe body drive case 19 in which a rotation base end portion 18 made of a round pipe is rotatably inserted is fixed to the stays 17 and 17a, and the injection pipe body drive case 19 is integrated with the rotation base end portion 18. With the triple pulley 20 inside, the ends of the wires 12a, 12b led out from the operation lever 12 for rotating the injection pipe body are fixed in the groove of the pulley 20 in a lap shape in a side view, and In the other groove, the other end of the coil spring 22 whose one end is locked to the fixed stay 21 is fixed,
The coil spring 22 is given a spring pressure corresponding to the weight of the upward rotating load of the injection pipe body so that the operation lever 12 can be operated vertically easily.

Now, the left and right ends of the rotating base end portion 18 are comb-shaped injection pipe bodies.
A connecting portion 18a for selectively connecting 15 and the horizontal injection pipe body 16 is formed. Fitting boss portions 23, 24 fixed to the inner ends of the lateral direction supporting members 15b, 16b are formed on the connecting portion 18a. It is designed to be inserted and connected through the plates 25 and 26, the bolt 27, and the nut 27a. Incidentally, as the connecting tool, a pin or an elastic engagement type stopper may be used instead of the bolt 27 and the nut 27a.

In the figure, 16d and 16'd are support tools, 16e is a stopper member, and 16f.
Are bolts, 18 ', 23', 24 ', 25', 26 'are bolt holes,
T is a crop such as soybean.

Fig. 7 is a pipe line diagram of the spreader, 28 is a return hose, 29, 30
Is a T-shaped joint, and 31 and 32 are nozzles.

In the above configuration, when the crop T is to be exterminated, the chemical solution is put into the tank 9 and the comb-tooth-shaped jet tube body 15 is attached to the liquid sprayer 1. At this time, the fitting boss portion 23 fixed to the inner end portion of the lateral support member 15b is inserted into the connecting portions 18a provided at both the left and right ends of the rotation base end portion 18, and the plate 24 and the rotation base end portion 18 are inserted.
The fitting boss portion 23 is fixed by the bolt 27 and the nut 27a, and the discharge hose 11 is connected to the dynamic injection 4 side through the T-shaped joint 29 and the joint portion 32.

If the machine body is moved forward, the liquid medicine is sprayed laterally from the nozzles 31 and 32 of each nozzle 15a to the stem culm of the crop T. Therefore, not only the front side of the leaf, but also the back side of the leaf and the stem portion of the chemical solution are evenly attached, and the control effect is further enhanced.

On the other hand, when performing water sprinkling work in a field scene, water is put in the tank 9 and the comb tooth-shaped injection pipe body 15 is rotated at the base end portion 18.
Then, the horizontal injection pipe body 16 is attached to the rotation base end portion 18 in the same manner as above, and water is sprayed from above toward the ground. The jet nozzles 16c of the horizontal jet pipe body 16 are arranged not in the horizontal direction like the jet nozzle ports 31 and 32 of the comb-shaped jet pipe pipe 15 but in a downward direction and in a horizontal row, so that there is no waste of water spraying and it is efficient. Watering work is performed. Further, the horizontal injection pipe body 16 has a smaller number of injection pipes than the comb-teeth-shaped injection pipe body 15 and can increase the spraying area for the same tank capacity.

Advantageous Effects of Invention As described above, according to the present invention, the traveling machine body is detachably mounted with the liquid sprayer, and the liquid sprayer has a long length along the stem-culm direction of the crop stems. Comb-shaped jet pipe bodies in which a large number of jet pipes are provided vertically on a lateral support member and horizontal jet pipe bodies in which a large number of jet nozzles are horizontally arranged in a state of being close to the lateral support member are detachably provided, respectively. Since the comb-tooth-shaped jet tube body and the horizontal jet tube body are replaceably mounted on the liquid spraying machine, the jet tube body can be selected according to the application such as pest control work or water sprinkling work, so that efficient work can be performed. At the same time, when the working machine is stored, by removing the injection pipe body, there is an effect that it can be stored easily even in a small space.
