Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a net supply device,

The present invention relates to a net supply apparatus to which an automatic type brake is applied and more particularly to a net supply apparatus for supplying a net to a baler by applying a brake for automatically fixing or releasing the net according to the operation of the baler, The present invention relates to a net supply apparatus which is formed with a simple structure so as not to require a separate power supply apparatus and which is equipped with an automatic brake for easy maintenance.

Generally, a baler is divided into a circular bale which is formed into a circular shape in a molding chamber and a rectangular bale which is formed by picking up a crop such as a rice straw or a grass pile according to a molding form. In recent years, Baylor, and small to medium-sized companies.

Such a baler has no self-propelled power, so it is connected to the rear of another traction drive source and pulled.

That is, the baler is connected to the rear of a tractor such as a tractor, and receives rotational force and hydraulic pressure from a PTO shaft installed in the tractor.

On the other hand, the baler is constructed by wrapping the outer circumferential surface of a roll baler, which is a bundle of bales, with a plastic net member of an appropriate length and discharging it.

Conventionally, the netting device for a baler is driven by receiving power from the net by interrupting the flow of the net as the electromagnetic clutch in the motor driving or the power of the baler.

In this way, power is transmitted to the bale chamber to introduce net into the bale chamber, and then the bale bundle rotated in the bale chamber is wound around the net so that the bale bundle is packed. In the beginning of the bale wrapping operation, There is a problem in that it is inconvenient for the operation and the standardization of the netting operation because the operation for setting the inflow length or setting the total netting length is performed manually by the operator on the baler side.

In addition, since the towing type baler can not be remotely controlled from the tractor, it is impossible to change the setting of the amount of netting in the tractor during the operation.

In addition, since it is impossible for the operator to accurately recognize the progress of the netting operation, there is a great risk of occurrence of safety accidents at work, and it is impossible to set the netting length and work correctly. It is difficult to perform the netting operation economically by making the setting of the netting length arbitrary for the operator.

In addition, since it is a complicated mechanical structure compared to a function, it is complicated in use, has a high manufacturing cost, increases the frequency of failure, low reliability of operation, and difficult maintenance.

In order to solve the above problems, Korean Patent Registration No. 10-1084509 (hereinafter referred to as Prior Art 1) discloses a "netting device for baler ".

In the prior art document 1, a netting device for a baler that is installed on a base plate 3 provided at one side of an inner side of a baler for bailing a crop and cuts the net by flowing a net for wrapping a bunch of bale, A net inflow drive roller 12 which is rotated in close contact with both sides to rotate by receiving a driving force of the driving source and an idle roller 13 which is rotated in elastic contact with the net inflow driving roller 12 upon receiving an elastic supporting force, (10); A movable cam 28 disposed on one side of the inflow means 10 and having a cam curved surface portion connected to a driving source for receiving a control signal of the microcomputer 30 and rotated, A cutter release bar 24 which is hinged and fixed at its upper end to the reset spring 23 and receives an elastic force to one side and which is rotated toward the other side by contact of the cam curved surface portion when the movable cam 28 rotates, A cutter operating bar 26 which is laterally disposed on an upper portion of the bar 24 and one end thereof is supported on the upper portion of the cutter release bar 24 and the other end is hinged and rotated downward when the cutter release bar 24 is rotated, And a cutter actuating spring (not shown) fixed to one end of the cutter actuating bar 26 and fixed to one side of the base plate 3 by vertically arranging the other end of the cutter actuating bar 26, 25) and the cutter operating bar (26) The cutter stopper 29 is provided with a cutter blade 29s provided on one side of the inflow means 10 when the cutter operating bar 26 is rotated downward, A cutter 27 for extending the cutter 27 and a cutter 27 vertically provided below the cutter actuating bar 26 to selectively project and retract the rod 21a in response to a control signal, And a cutter resetting cylinder 21 which is connected to one side of the rod 21a by a link 22 so as to rotate the lowered cutter operating bar 26 in contact with one side of the rod 21a when the rod 21a protrudes, (20).

In this prior art document 1, since the consumption amount of the net can be maintained at an optimal length, it is possible to increase the economical efficiency by suppressing excessive consumption of the net, and also to know the work situation (work amount, There is an advantage of enabling the packing operation.

In addition, since it is structurally simple, reliability of operation can be enhanced, so that operation loss due to malfunction can be minimized, and economical production and dissemination through cost reduction can be expected.

In particular, the cutting structure of the net has a cutter stopper (net fixing holder) that cuts the net to catch the net in the cutting operation at a position close to the cutting position along the orbit surrounding the cutter, As a result, accurate net cutting is possible, which leads to precise netting work.

However, in the prior art document 1, there is a problem in that the tension of the net can not be kept constant since no separate brake device for fixing the net is formed.

In addition, since the cutter reset cylinder and the micom for controlling the cutter reset cylinder must be applied to return the cutter release bar 24 to its original position, a separate apparatus is further needed, There is a problem in that the manufacturing cost is increased.
