[10] The screw conveyor according to any one of [1] to [9], wherein the crushing roll is provided with a plurality of teeth for separating forage separation.

[11] The screw conveyor as set forth in [10] above, wherein the screw is provided with a plurality of interchangeable forage cutting blades.

According to the present invention, since it takes no more than three minutes to crush a 500 kg roll veil, the production time of the feed product can be greatly shortened and the production amount can be increased.

In addition, since the forage such as rice straw or hay is firstly supplied to the feed blender in a state of being crushed, the load on the motor of the feed blender can be greatly reduced as compared with the case where the roll veil is directly fed.

In addition, since the forage such as rice straw isolated from the roll veil is softened in the process of being fed to the feed blender, both the palatability and digestibility of the feed product can be increased.

In addition, the softened forage can be fermented by natural seed bacteria possessed by the raw material itself without additionally adding a probiotic agent. This natural fermentation is stabilized within 3 days and can be kept for more than 6 months, but it can be obtained with cheap feed products.

As a result, it is possible to shorten the shipping date, reduce the cost, and increase the farm income.

Hereinafter, various embodiments of the screw conveyor equipped with the roughage shredding unit according to the present invention will be described in detail with reference to the drawings, but the scope of protection of the present invention should not be limited to the embodiments.

In other words, the embodiments described below are provided only for the purpose of enabling a person skilled in the art to fully and easily understand the technical idea of the present invention.

In the following embodiments, detailed description of known configurations is omitted.

≪ Embodiment >

1 to 2C are a perspective view, a plan view, a bottom view, and a side view of an embodiment of the present invention viewed from various angles.

As shown in these figures, a screw conveyor A equipped with a forage crushing unit according to an embodiment of the present invention is configured such that a main body portion and a roughage crushing unit 500 are combined.

The main body portion includes a trough 100 having an upper portion opened and a front and rear side end closed by an end plate 200 and having a discharge port 110 formed at a front end thereof and a bearing A screw S which is coupled to the bearing 300 of the waggon plate 200 so as to be rotatable in the trough 100 and which is mounted on the upper side of the trough 100 and which has a feed port And a lid 400 formed at the end.

The roughage shredding unit 500 further comprises a loading hopper 510 having a discharge port 511 to be connected to a supply port of the lid 400, a crushing roll 520 provided rotatably in the hopper 510, (Not shown) for rotating the roll 520 and interlocking means (not shown) for interlocking the operation of the drive means and the crushing roll. In the crushing roll, a large number of teeth 521 for separating a small amount of forage from the roll bale are formed.

모양으로 된 트윈 트로프이며, 배출구(110)는 트윈 트로프의 곡면부위에 1개만 형성된 공용(共用) 배출구이다. 이와 다른 구성으로서, 트윈 트로프의 곡면부위마다 배출구(110)가 형성되어도 된다.More specifically, the trough 100 has a cross-

And the discharge port 110 is a common discharge port formed only on the curved surface portion of the twin trough. As another configuration, the discharge port 110 may be formed for each curved surface portion of the tween trough.

In addition, the trough 100 according to the present embodiment is provided with openable and closable cleaning tools 120 on the left and right sides of the rear end.

The trough 100 and the lid 400 are bolted together so as to be disassembled and assembled, and the lid 400 is provided with an opening and closing type inspection opening 130. In Fig. 1, the check port 130 is shown as a square hole, but actually, an opening / closing door that covers the square hole is provided.

4 is a side view showing another embodiment of the present invention. The trough 100 is supported in an inclined state, more specifically, in a state in which the discharge port 110 is positioned higher than the roughage crushing unit 500 The lower structure 600 is provided.

Also, a plurality of moving wheels 610 are provided in the lower structure 600, which may be a caster, a tire, or a wheel moving along a rail.

FIGS. 3A to 3C illustrate various examples of a screw (S) that can be employed in a screw conveyor equipped with a roughage shredding unit according to the present invention. The inventors of the present invention have filed a patent application No. 10-2016-0033051 The reverse blade RB is welded to the section of one pitch or the reverse blade RB is welded to the section of about one pitch, The forward blade B may be welded to the entire section or the forward blade B may have a structure in which a plurality of blades C are detachably assembled. The reverse blade (RB) is installed at a position corresponding to the discharge port (110) of the trough (100).

Further, although not shown in the drawing, the crushing roll 520 and the electric motor are coupled by a coupling. When two or more crushing rolls are driven by a single electric motor, the crushing rolls 520 may be interlocked by chain or sprocket coupling or gearing.

According to the above-described structure, since the roughage is transferred through the screw conveyor provided with the roughage shredding unit, no residue is generated or dust and odor are spread in the worksite. This keeps the workplace clean.

Further, since the amount of the roughage separated from the roll bale is not small when the crushing roll once rotates, the load of the electric motor is small. Therefore, the crushing roll can be rotated at a high speed, whereby one 500 kg rollsheave can be crushed in 3 minutes.

In addition, the roughage separated from the roll bale is softened by the crushing roll and the screw, and the temperature rises by the frictional heat, so that it becomes suitable for fermentation. As a result, in the post-process, it is well mixed with other raw materials, and fermentation of fermentation and stabilization of nitrogen can be accomplished by the naturally occurring bacteria of the raw material itself without adding the probiotic agent separately. Such fermented fermented feeds can be expected to have effects such as shortening the date of shipment, improving the meat quality and grade, and increasing the weight of the shipment since the fermented fermented feed can not only be excellent in palatability and quality, but also can slow the digestion and stabilize the pH in the rumen. In addition, nitrogen-stabilized feeds can be stored for longer than six months without any change in quality.

Therefore, if a screw conveyor equipped with a roughage shredding unit according to the present invention is introduced, it is possible to remarkably increase farm income and greatly increase feed production.
