Description

[Detailed Description of the Invention] The present invention relates to a chaff dispersing device.

A conventional chaff spraying device is shown in FIG. In the figure, 1 is a spraying device case;
Reference numeral 1a denotes an air intake port provided in the dispersion device case 1. 2 is a dispersion duct, 2a is an air blowing port provided in the dispersion duct 2, and 2b is a chaff drop port provided in the dispersion duct. 3 is a roll-type chaff holder, and 4 is a chaff.

Next, the operation will be explained. In a device equipped with a roll-type chaff holder 3 on the top of a spreading duct 2 whose both ends are fixed to a spreading device case 1,
Air intake port 1a provided in the spray device case 1
Air with a pressure of P ₁ is blown from the chaff holder 2.
The chaf 4 located at the top is dropped and inserted into the chaf drop opening 2b provided in the dispersion duct 2 by wind pressure. Next, pressure is applied from the air outlet 2a provided in the distribution duct.
By blowing air _P2 , the chaff 4 which has been inserted into the dispersion duct 2 is released from the open opening at the other end of the dispersion duct 2 and dispersed. At this time, the pressure air P ₁ and
Since the relationship P ₂ is P ₁ >P ₂ , the chaf dropped and inserted from the chaf holder 3 is sucked into the dispersion duct 2 . By rotating the chaff holder 3 in the clockwise direction, the chaff placed between two sheets constituting the chaff holder 3 is discharged, and the chaff 4 is continuously supplied to the dispersing duct 2.

Since the conventional spraying device is configured as described above, the pressure adjustment between the pressure P ₁ blowing air into the spraying device case 1 and the pressure P ₂ blowing air into the spreading duct is delicate, and the chaff is placed at the chaff drop port 1a. It was difficult to properly insert the chaff into the chaff, and the chaf would get clogged near the chaff dropout, the chaff would be blown off by the pressure _P1 , or it would spill out near the chaff dropout.

This idea was made to eliminate the above-mentioned drawbacks of the conventional method. Instead of inserting the chaff into the chaff drop port with a pressure of P ₁ , a method was developed in which the chaff was sucked into the dispersion duct using the ejector effect. The object of the present invention is to provide a chaff dispersing device that can eliminate chaff clogging, chaff spillage, and chaff scattering and can spray chaff from a dispersion duct.

An embodiment of this invention will be described below with reference to the drawings. In Fig. 4, 1 is the spraying device case, 1b
1 is a ventilation hole provided in the dispersion device case 1, 3 is a chaff holder, 4 is a chaf, and 5 is a differential user, one end of which is fixed to the dispersion device case 1. 6 is a nozzle with one end fixed to the spray device case.

5b is a chaff suction port provided in the differential user 5 for sucking the chaff.

Next, the operation will be explained. In a device in which the chaff holder 3 is provided on the top of the differential user 5 whose one end is fixed to the spray device case 1, when air is blown into the inside of the nozzle 6, an ejector effect occurs between the nozzle 6 and the differential user 5, and the chaff holder 3 is A chaff 4 is sucked into a chaff suction port 5b provided in the differential user 5, and is sucked into the differential user 5. Next, an air flow is generated inside the differential user 5 toward the opening of the differential user 5 due to the eject effect, and the chaffs 4 are scattered by the air flow. or,
The chaf 4 is continuously supplied by rotating the chaf holder 3 in the CW direction. A ventilation hole 1b provided in the dispersion device case 1 is for air intake.

With this structure, pressure adjustment is extremely simple,
The chaff will not spill around the diff user or clog the chaff inlet.

As described above, this invention is equipped with a nozzle for sending air, a diff user whose tip extends beyond the tip of the nozzle on the outside of the nozzle, and a chaff inlet provided on the abdomen of the diff user, and air is blown from the nozzle. At the same time, since the chaff is fed from the chaff suction port, the chaff can be smoothly discharged from the tip of the diff user to the outside.
