Description

Technology Field

[0001] The present invention relates to a feed mixing device, and more specifically, to a feed mixing device that prevents spoilage of feed and maximizes the nutritional status of livestock by sterilizing the feed through a steam injection pipe section that injects high-temperature steam during stirring so that the feed is crushed by a stirring screw inside the housing. Background Technology

[0003] Generally, the method for packaging TMR or fermented TMR involves installing a packaging filling mixer on the upper part of the packaging machine to receive and store feed from a TMR mixer installed on the ground or underground, and packaging by a gravity-drop type packaging machine installed on the lower part.

[0004] There is a positional difference of about 10 meters between the feed mixing mixer and the packaging feed storage filling mixer on the ground, so there is a method of transporting feed from the feed mixing mixer to the packaging filling mixer by installing it at an angle using a belt or chain conveyor.

[0005] These conveyors must be installed with a small inclination angle within the optimal efficiency range; to achieve this, the feed mixing mixer and the packaging feed filling mixer are installed at a significant distance apart. This not only requires a large amount of space but also leads to problems such as dust scattering and feed falling outside due to structural issues, resulting in feed loss and contamination of the surrounding area.

[0006] Furthermore, conventionally, since feed is packaged without being sterilized during mixing, there is a problem in that harmful mold grows in the feed over time, and feeding the aged feed to livestock leads to diseases and a decline in their nutritional status.

[0007] Therefore, there is a need to improve this.

[0008] A related background technology is Korean Registered Patent Publication No. 0770367 (Registered on October 19, 2007, Title: Livestock Feed Fermentation Mixing Device). The problem to be solved

[0010] The present invention was created out of the aforementioned necessity, and aims to provide a feed mixing device capable of maximizing the nutritional status of livestock by preventing feed spoilage through the sterilization of feed by injecting high-temperature steam from a steam injection pipe section during stirring so that the feed is crushed by a stirring screw inside the housing. means of solving the problem

[0013] The above steam injection pipe section is characterized by having a plurality of injection guide holes formed on both sides at set intervals along the axial direction for injecting steam toward the stirring screw.

[0014] The above-mentioned spray guide hole portion is fitted with a diffusion guide nozzle to spray steam so as to diffuse it, and the diffusion guide nozzle is characterized by including a fitting portion that is fitted into the spray guide hole portion, a head portion that is extended in a conical shape with a diameter that gradually decreases toward the end of the fitting portion, and a spray hole portion that is formed through the circumferential surface of the head portion in a spiral trajectory along the axial direction to spray steam.

[0015] The above steam injection pipe section is provided with an auxiliary grinding section that protrudes between the injection guide holes to additionally grind feed, and the auxiliary grinding section is characterized by including a fixed section that protrudes from the circumferential surface of the steam injection pipe section, a grinding blade section that extends obliquely from the end of the fixed section to grind feed, and a grinding tooth section that is hinge-connected to the fixed section so that the rim protrudes to grind feed.

[0016] The circumferential surface of the steam injection pipe section is characterized by having a movement guiding member formed in an arrow shape to guide the feed to move toward the grinding blade section when the stirring screw stirs the feed. Effects of the invention

[0022] Furthermore, the terms described below are defined in consideration of their functions in the present invention, and these may vary depending on the intent or practice of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification.

[0026] As illustrated in FIGS. 1 to 7, a feed mixing device according to one embodiment of the present invention includes a housing (100), a stirring screw (200), a dispersion separator (300), and a steam injection pipe section (400).

[0027] The housing (100) accommodates feed introduced from the outside in a manner that allows it to be discharged. Here, the feed includes mixed feed (TMR) or fermented mixed feed (Fermented TMR).

[0028] This housing (100) serves to provide a space in which a stirring screw (200), a dispersion inducing member (300), and a steam injection pipe (400) are installed, and at the same time, a space in which feed can be received so as to be stirred.

[0029] At this time, the housing (100) is provided with an input guide (110) that guides the input of external feed and an output guide (120) that guides the discharge of the feed after mixing is complete.

[0030] Here, the input guide (110) includes an input hole (111) formed on the upper side of the housing (100) and an input opening / closing cover (112) hinged to the housing (100) to cover the input hole (111) so as to be openable / closeable.

[0031] Additionally, the discharge guide (120) includes a discharge hole portion (121) formed openly on the periphery of the housing (100), a guide member (122) provided in the housing (100) to communicate with the discharge hole portion (121) and forming a slide groove portion, an opening / closing door (123) fitted into the slide groove portion so as to be slidably movable to cover the discharge hole portion (121) so as to be openable / closed, and an operating cylinder (124) provided in the housing (100) to support the opening / closing door (123) so that the opening / closing door (123) can be slidably moved.

[0032] At this time, the operating cylinder (124) is rotatably connected to one side of the periphery of the housing (100) to extend and retract the rod to the other side, and the rod of the operating cylinder (124) is connected to the opening / closing door (123) to slide the opening / closing door (123) when extended and retracted.

[0033] That is, the opening / closing door (123) slides up to open the discharge hole (121) when the rod of the operating cylinder (124) is moved so as to be inserted into the operating cylinder (124) while protruding from the operating cylinder (124), thereby guiding the feed stirred in the housing (100) to be discharged to the outside, and slides down to block the discharge hole (121) when the rod of the operating cylinder (124) is moved so as to protrude from the operating cylinder (124), thereby preventing the feed stirred in the body (100) from leaking out to the outside.

[0034] Additionally, a discharge guiding member (125) is mounted on the guide member (122) at a downward angle to induce the feed to be discharged from the housing (100) when the discharge hole (121) is opened.

[0035] Accordingly, when the discharge hole (121) is opened by raising the opening / closing door (123), the feed that has been mixed in the housing (100) can be easily discharged to the outside of the housing (100) by its own weight along the inclined surface of the discharge guide member (125).

[0036] And, a pair of stirring screws (200) are rotatably provided on the lower side of the housing (100) to stir the feed fed into the housing (100) so as to be crushed.

[0037] To this end, a drive motor (210) connected to the stirring screw (200) is mounted on the circumference of the housing (100) to provide rotational force to the stirring screw (200).

[0038] A pair of dispersion-inducing members (300) are provided adjacently in the housing (100) to induce dispersion of the feed from the lower side of the housing (100) when the stirring screw (200) stirs the feed. These dispersion-inducing members (300) are provided to cover the lower side of the stirring screw (200) from the lower side inside the housing (100).

[0039] Meanwhile, the steam injection pipe section (400) is axially inserted into the housing (100) to be fixedly seated on the dispersion inducing member (300) and injects high-temperature steam. This steam injection pipe section (400) performs the function of sterilizing the feed by supplying steam at 120°C to 180°C to the feed introduced into the housing (100).

[0040] On both sides of the steam injection pipe section (400), a plurality of injection guide holes (410) for injecting steam toward the stirring screw (200) are formed at set intervals along the axial direction.

[0041] At this time, as shown in FIGS. 4 and 5, a diffusion guide nozzle (420) is fitted into the spray guide hole (410) to spray steam so that it is diffused.

[0042] This diffusion guide nozzle (420) includes a fitting part (421) that is fitted into the spray guide hole part (410), a head part (422) that extends from the fitting part (421) in a conical shape with a diameter that gradually decreases toward the end, and a spray hole part (423) that is formed through the circumference of the head part (422) in a spiral trajectory along the axial direction to spray steam.

[0043] Here, a screw thread is formed on the inner surface of the injection guide hole (410), and a male screw thread can be formed on the circumferential surface of the fitting coupling part (421) to be fastened to the female screw thread.

[0044] That is, when steam is injected from the injection guide hole (410), the steam passes through the fitting coupling part (421) and is filled in the head part (422), and is then injected through the injection hole part (423) by pressure.

[0045] Thus, the injection hole section (410) arranged in a spiral trajectory in the head section (421) can not only guide the steam injection speed to gradually increase as it moves toward the end of the head section (422), but also form a vortex inside the head section (422) so that the steam injection distance can be further improved.

[0046] Additionally, the steam injection pipe section (400) may be equipped with a control valve to control whether steam is injected from the outside of the housing (100).

[0047] In addition, as shown in FIGS. 6 to 7, the steam injection pipe section (400) may be provided with an auxiliary grinding section (500) that is formed protruding between the injection guide holes (410) to additionally grind the feed.

[0048] This auxiliary grinding unit (500) includes a fixed part (510) formed protruding from the circumference of the steam injection pipe part (400), a grinding blade part (520) formed extending obliquely from the end of the fixed part (510) to grind feed, and a grinding tooth part (530) hinged to the fixed part (510) so as to protrude a rim to grind feed.

[0049] That is, when the feed is rotated in the housing (100) along the rotational direction of the stirring screw (200), the feed is crushed in the rotational direction of the stirring screw (200) when it comes into contact with the crushing blade part (520), and can be crushed in the axial direction of the stirring screw (200) when it comes into contact with the crushing tooth part (530), so that the particles of the feed are crushed more finely and the stirring quality can be improved.

[0050] Additionally, a movement guiding member (600) may be formed protruding in the shape of an arrow on the circumference of the steam injection pipe section (400) to guide the feed to move toward the grinding blade section (520) when the stirring screw (200) stirs the feed.

[0051] Accordingly, when the feed is stirred by the stirring screw (200) in the housing (100) and the feed located between the stirring screws (200) comes into contact with the movement guiding member (600), it is divided by the movement guiding member (600) and then guided to move toward the grinding blade section (520).

[0053] Although the present invention has been described with reference to an embodiment illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0054] Therefore, the true technical scope of protection of the present invention should be determined by the claims below. Explanation of the symbols
