Description

[Detailed Description of the Invention] The present invention relates to a bale cutter for cutting bales of grass, rice straw, etc. compressed and packed into blocks by a hay baler into a state suitable for feeding.

A bale cutter for cutting bales has a horizontal rotating shaft supported on the machine frame, and a number of rotating blades are attached to the rotating shaft in parallel. The cylindrical body that accommodates the bale is placed on the top side of the machine frame in a state where it rotates while protruding from the top side, and the cylindrical body that accommodates the bale is placed in such a position that its axial direction is in the vertical direction, and the axis of rotation is in the vertical direction. The cylindrical body is mounted so that it can rotate freely, and the cylindrical body and the rotating shaft are transmitted to the output shaft of the prime mover for driving rotation, and the cylindrical body and the rotary blade are driven. When a bale is fed into the cylindrical body in a rotating state, the bottom side of the bale receives the cutting action of a large number of parallel rotating blades. This is a special cutter that can be used to cut bales by changing them sequentially, and cutting the bales by unraveling them and cutting them sequentially from the bottom side of the bales.

For this reason, it is not very popular because it is expensive and its range of use is limited.

The purpose of the present invention is to enable bale cutting to be carried out using straw cutters owned by ordinary farmers, thereby making it possible to supply bale cutters at a low cost.

In the present invention, for this purpose, a feed roll chamber that accommodates and supports the feed roll is provided in front of the entrance of the cutting chamber that accommodates the cutting mechanism, and a supply gutter is provided in front of the receiving opening of the feed roll chamber. A cover that covers the upper surface side of the base end of the supply gutter is removably attached to the straw cutter equipped with the straw cutter, and a rotating shaft on which a number of cutting blades are supported in parallel is mounted inside the cover. The present invention proposes a bale cutter which is arranged so as to be transverse to the left and right, and whose shaft is mounted on the left and right side walls of the cover, and whose rotating shaft is transmitted to a rotating shaft provided in the body of the straw cutter.

Next, embodiments will be described in detail with reference to the drawings.

FIG. 1 is a side view of the entire bale cutter A according to the present invention, where a is a straw cutter, 1 is the main body of the straw cutter a, 2 is its supply gutter, and 3 is the base end of the feed gutter 2. A cover is removably attached to the top side, 4 is a rotating shaft supported by the cover 3, 5
shows a transmission pulley attached to the outer end of the rotating shaft 4 in order to conduct the rotating shaft 4 to the rotating shaft provided in the cutter body 1.

As shown in FIG. 2, the straw cutter a is constructed by arranging the cutter main shaft 11 that crosses the cutting chamber 10 at the axial center of the cutting chamber 10 mounted on the frame of the cutter body 1. The cutter main shaft 11 is mounted on the frame of the main body 1, and the rotary blades 12, 12 are mounted and supported via the cutter mounting bracket, and the cutting chamber 1 is
The rotary blade 1 is located at the part facing the entrance 10a of the
2, 12 and the corresponding fixed blade 13 to the cutter body 1.
The entrance 1 of the cutting chamber 10 is fixed to the frame of the cutting chamber 10.
A feed roll chamber 15 is installed on the front surface of the feed roll chamber 15, which accommodates and supports a pair of vertically opposing feed rolls 14, 14. The supply gutter 2 that protrudes long toward
is detachably assembled, and at the bottom of the supply gutter 2 there is a roll 2 that is pivotally supported at the base end and tip end of the supply gutter 2.
This is a normal straw cutter that is equipped with a supply conveyor 23 that is made by endlessly wrapping a conveyor belt 22 around the cutter main shaft 11 and the rotating shaft of the roll 21 on the driving side of the supply conveyor 23. When the material to be cut is supplied into the supply gutter 2 while the output shaft of the motor M supporting the frame of the cutter body 1 is being driven and rotated, the supply conveyor 23 moves the material between the feed rolls 14 and 14 facing each other. The material is fed into the gap, sequentially fed into the cutting chamber 10 by the feed rolls 14, 14, cut by the fixed blade 13 and the rotary blade 12, and discharged from the discharge port 10b of the cutting chamber 10. The fact that the straw is discharged outside the machine via the discharge gutter 16 connected to the straw cutter 10b is no different from the previous cylinder-type straw cutter.

The cover 3 attached to cover the upper surface side of the base end of the supply gutter 2 is formed into an inverted channel shape when viewed from the front, and has left and right side walls 30, 3.
0, the rear end edge of the side walls 30, 30, and the rear end edge of the top plate 31 are attached to the upper surface of the left and right side walls of the supply gutter 2, and the front end surface of the base end. It is attached to the formed assembly flanges 2a, 2a, and closed and connected by set bolts 33, so that it can be attached to and detached from the supply gutter 2.
The assembly collar portions 2a, 2a provided on the supply gutter 2
is also used when assembling a safety cover (not shown) in place of the cover 3.

As shown in FIGS. 3 and 4, the rotating shaft 4 supported by the cover 3 has a large number of disk-shaped cutter mounting plates 40 between which collars 41... The cutting blades 40 are supported in parallel via..., and each of the blade mounting plates 40... has a cutting blade 4 formed in a substantially triangular shape, as shown in FIG.
A plurality of screws 2 are attached radially by set screws 43, respectively. The rotating shaft 4 has its left and right shaft ends connected to the left and right side walls 3 of the cover 3.
0, and one shaft end thereof extends from the bearing part 44 to the cover 3.
A transmission wheel 45 is assembled to protrude laterally. Then, a transmission belt 47 is wrapped around this transmission ring 45 and a transmission ring 46 provided on the cutter main shaft 11 which is pivotally supported on the cutter main body 1, and the transmission is transmitted to the rotating shaft of the cutter main body 1. The cutter body 1 is driven to rotate.

The bale cutter A according to the present invention constructed in this way operates as follows.

When a bale B of grass, rice straw, etc. compressed and packed using a baler is put into the supply gutter 2, the supply conveyor 23, which is stretched over the floor of the supply gutter 2, carries the bale B to the base of the supply gutter 2. The bale B is fed toward the end side, and the cutting blade 42, which rotates and is pivotally supported by the cover 3 that covers the base end of the supply gutter 2, comes into contact with the bale B and cuts the contact area, As a result, the bale B is in an unraveled state, and the feed rolls 14, 14 transfer the bale B in that state to the cutting chamber 10.
The materials are sequentially fed into the interior, cut by the rotary blade 12 and the fixed blade 13, and then discharged from the discharge port 10b.

In this state, even if the bale B is supplied to the supply gutter 2 of the straw cutter a, the bale B is
Since it does not fit into the opposing gap of 4, the straw cutter a
However, in this embodiment, cutting is not possible with a large number of cutting blades 42 arranged in parallel, and only the packaging is unraveled and almost no cutting is performed. A large number of cutting blades 42 arranged in parallel at the base end unravel the bale B, and the feed rolls 14, 14 feed it into the cutting chamber 10 and cut it, so that the unraveling of the bale B is easy. You will be able to do this using cutter a.

As explained above, the bale cutter according to the present invention is provided with a rotary shaft supporting a large number of rotary blades in parallel at the base end of the supply gutter of the straw cutter, which unravels the bale and feeds it into the straw cutter for cutting. Since it is designed to cut the bale, it is possible to cut the bale using a straw cutter, and the rotating shaft that supports many rotating blades in parallel can be freely attached to and removed from the base end of the supply gutter. Since the cutter is pivoted on the cover that is attached to the cutter and driven by transmission with the rotating shaft on the cutter body side, the burden on the user is essentially just the rotating shaft that supports the rotating blade in parallel. This makes it possible to provide bale cutters at a significantly lower cost.
