Description

Rice straw cutter

The present invention relates to a rice straw cutter for cutting rice straw into a livestock feed, and more particularly, to a rice straw cutting machine that automatically transfers rice straw and slices it into a band saw, thereby significantly increasing cutting and hourly throughput, and improving working safety.

Rice straw is a stem of rice which has been separated from rice, and is used for various purposes.

In order to be used as a feed for the livestock, it is necessary to cut it to a certain length. In the related art, a method of cutting the plate by a rotary cutter was placed on a workbench by hand.

However, in this case, since the working environment is made by manual work, work safety and work yield are reduced, and dust generation is harmful to the human body. Especially, rice straw is made of fiber, which is difficult to cut, so the work efficiency is significantly lowered due to frequent breakdowns of the machine.

Therefore, in the cutting of rice straw, safety of work is first required, cutting must be well made, and cutting throughput must be good.

The present invention was devised in view of the above circumstances, and an object of the present invention is to provide a rice straw cutter which significantly increases cutting and hourly throughput to be sure by automatically transferring rice straw and cutting into a band saw, and improves work safety.

Specific means of the present invention for achieving the above object,

Drive pulleys 31A and 31B are connected to each output shaft of the band saw driving motors 30A and 30B, and the driven pulleys 32A and 33B are connected to the drive pulleys 31A and 31B via the pin-belts 33A and 33B. 32B) is connected.

Driving wheels 50A and 50B are connected to the other ends of the driving wheel rotation shafts 51A and 51B to which the driven pulleys 32A and 32B are connected, and the driving wheel rotation shafts 51A and 51B are on the frame 10 side. It is rotatably installed in the bearing 53 in the bearing housing 52 which is fixed to the bearing.

A driven wheel 60A and 60B are connected to the band saw tension adjusting means above the driving wheel 50A and 50B on the driven wheel mount 20 placed on the upper portion of the frame 10.

Each of the plurality of pairs of driving wheels 50A, 50B and driven wheels 60A, 60B has a band saw 70A for cutting rice straws 200A, 200B, 200C, which have been transferred by rice straw conveying means to be described later, at predetermined intervals. 70B) is wound and connected.

As shown in FIGS. 3 and 5, the tension adjusting means 80 of the band saws 70A and 70B attaches a pair of guide blocks 81A and 81B to the driven wheel mount 20, respectively. The axial supports 82A and 82B are slidably coupled to the guide blocks 81A and 81B through pins 85A and 85B so as to be slidable within a predetermined height, and to the axial supports 82A and 82B. The tension adjusting bolts 84A and 84B are coupled to the pins 87A and 87B, and the tension adjusting handles are screwed to the threaded portions of the tension bolts 84A and 84B and seated on an upper surface of the driven wheel mount 20. The tension of the band saws 70A and 70B is made by adjusting the height of the shaft supports 82A and 82B with 86A and 86B.

That is, as the tension guide handle (86A) is tightened and released as guided by the guide block (81A) guided by 81A guide shaft 81A is adjusted up and down to adjust the tension of the band saw (70A).

The upper surface of the frame 10 is a rice straw conveying means for driving the straw by driving by the conveyor driving motor 40, the drive roller 102 and the driven roller 104 on the left and right sides of the upper surface of the frame 10 ) Is rotatably installed, a small diameter sprocket 105 is installed on the drive roller shaft 103 of the drive roller 102 and connected to the axial force end of the drive motor 40. It is connected to the chain 107, the drive roller 102 and the driven roller 104 is connected to three rice straw transport belt (112).

In addition, the driven roller 104 has a support shaft plate 120 having a long hole 121 at both upper left sides of the frame 10 as a means for adjusting the tension of the rice straw conveying belt 112. The support shaft 114 of the driven roller 104 is installed to be movable in the long hole 121 of the support shaft plate 120, the support shaft 114 is the support shaft plate 120 side It is installed to be movable by the tension adjusting bolt 124 screwed on.

In addition, on the upper surface of the frame 10, straw straw guide plates 132A and 132B are installed as shown in FIG. 2 apart from the width of the straw so as to guide the straw over the transfer direction of the straw.

On the other hand, the band saw (93A, 93B) as a guide support means for preventing the bending of the band saw when cutting the straw during rotation and at the same time to correct the cutting direction, as shown in Fig. 3 the tee saw on the driven wheel mounting table 20 side The upper bearings 92A and 92B are fixedly installed on the bearing blocks 94A and 94B so as to rotate and guide the upper portions of the 70A and 70B, and the bearing blocks 94A and 94B are fixed to the fixing blocks 95A and 95B. It is guided to and is height-fixed by the bolt (B).

In addition, upper guide blocks 93A and 93B having cut band support grooves 93-1 through which the band saws 93A and 93B are inserted and guided are provided on the bottom surfaces of the bearing blocks 94A and 94B.

In addition, the lower bearings 96A and 96B and the lower bearings 96A and 96B are installed on the upper portion of the frame 10 as shown in FIG. 4 so as to rotate and guide the lower portions of the band saws 70A and 70B. Lower guide blocks 97A and 97B having band saw support grooves 97-1 to guide 93B are provided.

In the drawings, reference numeral 150 denotes a safety cover, 160 denotes a safety door, and 170 denotes an idle roller.

The operating state of this embodiment configured as described above will be described.

First, when power is supplied to the band saw driving motors 30A and 30B and the conveyor driving motor 40, the driving wheel rotation shafts 51A and 51B rotate through the X-belts 33A and 33B, and this driving shaft rotation shaft The band saws 70A, 70B and the driven wheels 60A, 60B rotate through the drive wheels 50A, 50B connected to 51A, 51B.

At the same time, the large diameter sprocket 106 connected to the output shaft of the conveyor driving motor 40 rotates, and the rotational force of the large diameter sprocket 106 causes the small diameter sprocket 105 to pass through the chain 107. As it rotates, the drive roller 102 rotates the driven roller 104 by the transfer of the straw transfer belt 112.

Therefore, when the straws 200A, 200B and 200C are sequentially placed on the upper surface of the rice straw conveying belt 112 of the driven roller 104, the rice straw is conveyed to the driving roller 102 side along the rice straw conveying belt 112. .

In this way, the straw is guided by the straw guide boards (132A, 132B) on the left and right side and is led by the straw transfer belt (112) to reach the band saws (70A, 70B) by the cutting edge of the rotating band saw (70A, 70B) The straw is cut rapidly in three equal sections vertically from this shear plane side.

The straw bales cut in this way are continuously placed on the straw transport belt 112 and fall to the rear side of the driving roller 102.

According to the embodiment of the present invention operating in this way it is possible to significantly increase the amount of cutting work by several times compared to the method of placing it on the work table by the conventional hand and cutting it by the rotary cutter.

Moreover, since the fiber of a straw straw is sawn and cut as it is, cutting property is excellent.

In addition, simply put on the rice straw transfer belt is automatically cut process without the need to hold by hand, high working safety, and there is little dust generation and noise can optimize the working environment.

Meanwhile, in the above embodiment, two band saws 70A and 70B are cut to the straw end, but the present invention can be configured to support one band saw in a zigzag up and down by a cutting width and to be driven through one driving means. It may be.

In addition, the rice straw cutter of the present invention can be driven by using the power from the power unit (P.T.O) of the tractor or tiller and using a reducer / accelerator.

As described above, according to the present invention, the cutting method for cutting rice straw is improved by an automatic method using a saw, which is excellent in cutting property, and can greatly increase the yield. It can be a starting point.
