Description

Rice straw round bale chopper {TRACTOR ATTACHABLE ROUND BALE CHOPPER FOR RICE STRAW}

The present invention relates to a straw straw round bale chopper, and more specifically, a straw straw bale that is three times or more tougher than a forage crop, such as rye, is cut to about 10 cm so as to be suitable for cows, and is then supplied to the thread or TMR mixer of the barn. The straw bale chopper is designed to reduce the loss of rice straw and increase its utilization.

In general, in Korea, there is no machine for automatic cutting of straw straw bales, so the tangled rice straw is fed to the cows, so that the loss caused by stepping and shedding when the cows eat is 25% of the feed amount, which is supplied to the TMR mixer. In this case, the bale is pulled out by manpower and cut using a small rice straw cutter (3 to 5 PS) and supplied to the TMR mixer by manpower.

In the present invention, when cutting rice straw, which is three times tougher than feed crops such as rye, a fan-shaped blade is attached to reduce cutting force, and is primarily cut in the longitudinal direction, and secondly cut by the blade attached to the flywheel, and attached to the flywheel. It is to provide a new type of straw straw bale chopper that allows the fan to rotate and blow out the cut straw.

Another object of the present invention is to improve the workability by automatically conveying and supplying a straw straw bale of about 200 to 300kg by a chain conveyor, and at the same time, a 40-horsepower tractor with a straw straw bale chopper is widely distributed in Korea. It is intended to be available.

In order to achieve the above object, the present invention is a circular bale chopper for cutting a straw straw to a predetermined size in order to feed cows, the bottom of the loading box is installed so that the circular bale transfer bar is circulated and rotated by a transfer chain, the main body A primary cutting device is installed at the rear of the cutting unit and a secondary cutting device is installed at the front of the cutting unit. The primary cutting device has a plurality of primary fixed blades protruding downward from the bottom of the fixed support, and a fan shape is formed on the outer peripheral surface of the cylindrical rotating drum. The first rotary blade and the lug of the shape is radially coupled at regular intervals, the secondary cutting device is formed with an outlet on one side of the cover, the outlet angle is controlled by the wire and the tension spring and the discharge angle control bar The discharge guide plate is combined to enable it.

In the present invention as described above, the lug coupled to the rotating drum of the primary cutting device is a straight line contacting the circumference of the rotating drum and the angle of 있도록 40 ~ 80 ° between the primary rotary blade so as to roll over the cut rice straw It is characterized by consisting of a length of 1 ~ 4 ㎝ shorter than the primary cutting blade.

Figure 4 is a right side view showing a straw round bale chopper according to the present invention, Figure 5 is a left side view showing a straw straw round bale chopper according to the present invention, Figure 6 is a plan view showing a straw round bale chopper according to the present invention, At the bottom of the loading box 2 coupled to the rear of the main body 10, a circular bale transfer bar 4 circulated and rotated by the transfer chain 3 is installed and the circular bale supplied to the loading box 2 is first. It shows that it is supplied to the cutting device 20 automatically.

Referring to the use state of the present invention as follows.

As shown in Figures 1 to 6, using a straw straw bale chopper (1) according to the present invention to cut a straw straw bale, which is three times more tough than a forage crop round bale, such as rye, first, PTO (drawings) (Not shown) to couple the PTO connecting shaft 40 of the round bale chopper (1) so that power can be transmitted, and connects the drawbar connecting shaft (51) to the tractor.

In this way, when the circular bale chopper 1 is connected to the tractor so that power can be transmitted, when the circular bale to be cut is supplied to the loading box 2, the circular bale circulated and rotated by the transfer chain 3 The round bale is introduced into the primary cutting device 20 by the bale transfer bar 4.

Therefore, the straw straw bale introduced into the primary cutting device 20 is coupled to the first fixed blade 12 and the rotating drum 13 coupled to the fixed support 11 to the first rotary blade 14 to be rotated It is cut in the longitudinal direction.

At this time, the rotary drum 13 of the primary cutting device 20 at the angle between the tangential circumference of the rotary drum 13 and the primary rotary blade 14 between the primary rotary blade 14 and the angle of ∠40 ~ 80 ° 14 Lug 15 having a length of 1 to 4 cm shorter than) is coupled at equal intervals so that the rice straw cut by the primary rotary blade 14 is rolled up.

In this way, the rice straw first cut in the longitudinal direction by the primary cutting device 20 is introduced into the secondary cutting device 30 and the secondary cutting is made, the rice straw introduced from the primary cutting device 20 The secondary rotary blade 29 coupled to the flywheel 28 and the secondary fixed blade 27 'coupled to the frame 27 is secondary cut in the transverse direction.

In this state, the secondary cut straw bale is discharged to the outside through the outlet 22 formed in the cover 21 is supplied to the irradiation of the barn or TMR mixer, the cut straw straw bale is the outer peripheral surface of the flywheel 28 It is discharged to the discharge port 22 by the wind generated by the fan 29 'coupled to.

In addition, since the discharge guide plate 26 is coupled to the discharge port 22 so that the angle can be adjusted by the wire 23, the tension spring 24, and the discharge angle adjusting bar 25, the discharge angle adjusting bar 25 By adjusting the angle of the discharge guide plate 26 by using), the discharge angle of the straw bale to be discharged can be arbitrarily adjusted.

In this way, the straw straw bale, which is three times tougher than feed crops such as rye, is first cut in the longitudinal direction by the primary cutting device 20, and subsequently, in the secondary cutting device 30 in the horizontal direction. Since it is cut and shortened, it is possible to prevent the loss (approximately 25% of the feed amount) caused by the cow stepping on and spilling when feeding the uncut rice straw round bale to the cow.

As such, by using the straw straw bale chopper according to the present invention, it is possible to feed the cows without cutting the straw from the farmhouse or cut it with a crest cutter for small soybeans, thereby maximally reducing manpower and work costs. In addition, it is possible to save the straw straw that is lost or dropped on the floor during feeding without cutting the straw is efficient and economical effect can be obtained.
