Description

Opening and closing the rear chamber of the bailer

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear chamber opening / closing hook of a bailer, and more particularly, to a rear chamber opening / closing hook of a bailer that improves the accuracy of operation according to a pressure value measurement using a load cell and does not cause malfunction due to simplification of the structure.

It is also important to use high quality forage as well as utilization in order to produce high quality livestock products with a balanced feed system suitable for the ratio of 60: Mechanization that can be packed is important to increase utilization. In general, a compaction and binding apparatus called a baler or a baler is a device for compacting and binding a forage crop after harvesting into a predetermined form and forming it into a bale. Such molded veils are generally discharged from the baler and stored as silage after additive treatment and vinyl winding.

In Korea, 200 to 2.2 million tons, or 40% of the 5 million tons of rice straw production in 2009, are used as feed. In particular, by treating with additives such as lactic acid bacteria, it is expected to save about 500 kg of mixed feed per year. Therefore, the preparation of rice silage using machinery such as Baylor should be strongly encouraged.

On the other hand, the baler picks up and transports the crop, and is formed into a cylindrical shape while being rotated by a plurality of forming rollers installed in the chamber. When the forming is completed, the rear chamber is opened and discharged.

1A and 1B, the conventional baler is connected to the actuator 3 installed in the rear chamber 2 of the chamber 1 to discharge the bail after the formation of the bail is completed, A second operating member 6 in the form of a hook connected to be slidable forward of the first operating member 5 is inserted into the projection 2 of the rear chamber 2, (2a).

A control port 7 is formed through the upper portion of the first operating port 5 and adjustable in moving distance along the second operating port 6. The control port 7 is aligned with the control port 7, 1 opening 5 is provided with a tapered portion 8 provided at the upper portion of the operation opening 5.

That is, when the bail is molded in the chamber 1 and pushes the rear chamber 2, the second actuating member 6 hooked on the protrusion 2a is pulled, and the adjusting member 7 is connected to the stopper 8 The first actuating tool 5 is rotated downwardly by the drawing operation of the actuator 3 so that the second actuating tool 6 connected to the first actuating tool 5 is engaged with the protrusion 2a and the engaging force So that the rear chamber 2 is operated to be opened.

However, the conventional opening / closing apparatus has a problem in that it is deformed beyond the allowable size of the veil if the distance is adjusted too far by controlling the distance and the distance between the regulator and the earth.

Further, when the adjuster is adjusted too close to the tapered portion, the bale is formed to be smaller than the allowable size.

In addition, since the controller and the sensor are exposed to the outside, there is a problem that smooth detection can not be performed when the foreign object is caught.
