Fig. 4 shows a breaker safety device, Fig. 5 shows a side safety device of the crusher safety device, and Fig. 6 shows a rear safety device of the crusher safety device.

Referring to FIGS. 4 to 6, the tree branching crushing apparatus according to an embodiment of the present invention may include a crusher safety apparatus. The crusher safety device may include a lateral safety device 100 and a rear safety device 200.

When the driver is excessively close to the side of the main body frame 10 during the tree branching operation, part of the driver's body is sucked into the drawing roller 20 for guiding the branch of the tree to the cutter portion, It is a safety device to prevent such a serious accident such as cutting.

The side safety device 100 includes a pair of side safety bars 110a and 110b, a first driving link 120a, a second driving link 120b, and a first safety link 130. [

The left side safety bar 110a and the right side safety bar 110b are formed in the shape of a long bar along the side of the main body frame 10 and the left side safety bar 110a and the right side safety bar 110b, Is guided by a guide slot (12) coupled to the body frame (10). As a result, when the driver approaches the left or right side and the body of the driver touches the left side safety bar 110a or the right side safety bar 110b, the left side safety bar 110a or the right side safety bar 110b The first driving link 120a or the second driving link 120b coupled to the left side safety bar 110a and the right side safety bar 110b are rotated in the direction of the center of the main body frame 10 do.

One end of the first driving link 120a is coupled to the left safety bar 110a and one end of the second driving link 120b is coupled to the right safety bar 110b. The other end of the first driving link 120a and the second driving link 120b are hinged by the engaging pin 122 and the second driving link 120b is hinged by the first rotating pin 121 to the main frame 10 ), Preferably to be pivotally coupled to the lever operating panel 50.

The first driving link 120a or the second driving link 120b is rotated when any one of the left side safety bar 110a and the right side safety bar 110b is pressed. Since the first driving link 120a and the second driving link 120b are hinged to each other by the coupling pin 122, any one of the first driving link 120a and the second driving link 120b is rotated , The other one will rotate. When the first driving link 120a and the second driving link 120b rotate, the other ends of the first driving link 120a and the second driving link 120b, which are hinged by the engaging pin 122, 10).

The connection link 123 is coupled to the first driving link 120a.

The connecting link 123 functions to transmit the rotation of the first driving link 120a to the first safety link 130. [ It is natural that the connection link 123 may be connected to the second driving link 120b instead of the first driving link 120a. One end of the connection link 123 is fixedly coupled to the first driving link 120a and the other end is hinged to be rotatable with respect to the first safety link 130. [

When the other end of the first driving link 120a and the second driving link 120b move toward the rear of the main body frame 10, movement of the first driving link 120a by the connecting link 123 is transmitted to the first safety link 130 so that the first safety link 130 rotates about the second rotation pin 131. When the first safety link 130 rotates, the leading end of the first safety link 130 pushes the drawing roller driving lever 331, which is advanced to drive the drawing roller 20, backward. When the drawing roller driving lever 331 is retracted, the drawing roller 20 is controlled to be in a stopped state.

The drawing roller 20 and the cutter section are driven by the drawing roller driving lever 331 and the cutter driving lever 341. When the drawing roller 20 rotates in a state where the cutter section is not rotated, 11) may be caused by a tree branch. When the tree branch is inserted, it must be shattered by the cutter part and discharged to the outside. In order to prevent this, in a state in which the cutter driving lever 341 is in the advanced state, that is, when the cutter unit is stopped, the drawing roller driving lever 331 is prevented from being in a forward state, that is, the drawing roller 20 is in a rotating state There is a need. For this purpose, an interlocking link 135 is provided.

The interlocking link 135 is formed to extend in the direction opposite to the first safety link 130 and has one end coupled to the first safety link 130 and the other end positioned in front of the adjacent cutter driving lever 341 , The drawing roller driving lever 331 rotates in conjunction with the first safety link 130 during forward movement.

When the cutter drive lever 341 is retracted and the cutter portion is in the drive state, there is no restriction on the rotation of the interlocking link 135 and the draw roller drive lever 331 can be advanced. However, The cutter driving lever 341 prevents the interlocking link 135 from rotating so that the interlocking roller driving lever 331 can not be advanced.

An elastic member (not shown) such as a spring may be coupled to the interlocking link 135. When the force applied to the left side safety bar 110a or the right side direction electron 110b is removed after the side safety device 100 operates, one end of the elastic member is moved to the interlocking link 135 And the other end can be coupled to the lever operation panel 50. It goes without saying that the elastic member may be coupled to the first safety link 130 and the lever control panel 50.

Mounting of the rear safety device 200 is mainly intended to prevent injury to the driver by knocking the driver while the vehicle is moving in the reverse drive mode. If the driver does not set a certain distance during the backward movement of the tree branching crushing device and the body part of the driver touches the main body frame 10, the driving levers 311 and 321 are restored to the neutral state and the driving of the tree branching crushing device is stopped .

The rear safety device 200 includes a pivot frame 210, a rear safety bar 220, a second safety link 230 and a third safety link 240.

The pivot frame 210 is rotatably coupled at one end to the rear upper portion of the main body frame 10, that is, to the end of the lever control panel 50. The rear safety bar 220 is coupled to the other end of the pivot frame 210. When the driver approaches the rear and the body of the driver touches the rear safety bar 220, the rotation frame 210 rotates.

The rear safety bar 220 may be installed in the lateral direction of the main body frame 10 so as to facilitate the driver's body contact when the driver approaches the rear of the vehicle.

The second safety link 230 and the third safety link 240 are coupled to the rotation frame 210.

The second safety link 230 is coupled to the pivot frame 210 and extends so that the leading end thereof is located at a lower rear adjacent position of the drawing roller driving lever 331. [ When the driver approaches the back of the main body frame 10 excessively, the body of the driver contacts the rear safety bar 220 to press the rear safety bar 220, whereby the turning frame 210 rotates forward 2 safety link 230 presses the lower portion of the drawing roller driving lever 331. [ As a result, the drawing roller driving lever 331 is moved backward, so that the drawing roller 20 is stopped.

The third safety link 240 protrudes forward of the pivot frame 210 and is located behind the drive levers 311, When the body of the driver presses the rear safety bar 220 while the driving levers 311 and 321 are in the backward state, the rotating frame 210 rotates forward and thereby the third safety link 240 is rotated by the driving lever 311 , 321 to restore the drive levers 311, 321 to the neutral state.

As described above, the crusher safety device allows the side safety device 100 or the rear safety device 200 to operate when the driver approaches the side or rear of the main body frame 10 within a certain distance during the tree crushing operation, The drive of the tree branching crushing device or the pulling-in roller 20 can be stopped to ensure the safety of the driver.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. And such changes are, of course, within the scope of the claims.
