Description

Technical Field

[0001] The utility model relates to the technical field of silage feed processing, and more specifically, to a silage feed compression and fermentation device. Background Art

[0002] Silage feed is a type of feed that is made from plant-based feeds with high moisture content through sealing and fermentation, and is mainly used for feeding ruminants. During the production and processing of silage feed, it needs to be subjected to compression and fermentation treatment.

[0003] However, when the current silage feed compression and fermentation device needs to obtain a sample inside the fermentation tank for fermentation evaluation, the fermentation box needs to be opened to take the sample. At this time, air will enter the inside of the fermentation tank, and the user needs to evacuate the fermentation tank again after sampling, which is rather troublesome.

[0004] After retrieval, a Chinese patent with the authorization announcement number CN221235594U discloses a fermentation device for silage feed. This structure drives the abutting plate to abut between the rotating plates by pulling the pull rod upward, so that the rotating plates open. Then, hold the sleeve and the inner rod to compress the spring to open the grasping plate. Move downward so that the sampling assembly contacts the silage feed. At this time, release the sleeve and the inner rod, and the spring resets to drive the sleeve and the inner rod to reset, thereby causing the grasping plate to reset. The bent and rotating grasping plate will grasp the silage feed. Move the sampling assembly upward so that the grasping plate enters the transfer cylinder. Release the pull rod so that the rotating plates seal the transfer cylinder. Open the sealing cover to obtain the silage feed inside the transfer cylinder, which can effectively reduce the air entering the tank body during sampling.

[0005] However, when this structure is actually used, when evacuating the inside of the fermentation tank through a vacuum pump, once the silage feed contains dust and impurities, it is easy to cause the impurities and dust to enter the inside of the pipeline along with the air. In the long term, the pipeline will be blocked, making it difficult to clean and affecting the vacuum pumping effect. In view of this, the present utility model proposes a silage feed compression and fermentation device. Summary of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the present utility model provides a silage feed compression and fermentation device to solve the problems raised in the above background art.

[0008] It can be seen that in the above structure, the feed pipe and the material taking port are used for the feeding and material taking operations of silage. The negative pressure pump can evacuate the inside of the fermentation tank through the vacuum hose, ensuring that the silage inside the fermentation tank can ferment under anaerobic conditions and reducing the impact of aerobic bacteria on the silage.

The connection between the sealing plug and the fermentation tank is detachably connected by screws. Two rectangular grooves are provided on the surface of the sealing plug.

[0010] In order to seal the feed pipe and prevent air from entering the inside of the fermentation tank, preferably, the feed pipe is inclined and installed on the outer wall of the fermentation tank, and a sealing pipe cover is hinged at one end of the feed pipe. The inner diameter of the sealing pipe cover is larger than the outer diameter of the feed pipe.

[0011] In order to seal the material taking port and further improve the vacuum environment inside the fermentation tank, preferably, a sealing door is installed inside the material taking port through a hinge. A pulling groove is provided on the surface of the sealing door.

[0012] In order to compress the silage inside the fermentation tank, discharge the air inside the silage, and improve the fermentation effect of the silage, preferably, a cylinder is provided at the top of the fermentation tank.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown in the Figures 1-5 silage feed compression and fermentation device, it includes a fermentation tank 1. A plurality of support legs 18 are welded to the bottom of the fermentation tank 1. A feed pipe 2 is communicated with the outer wall of the fermentation tank 1. A material taking port 3 is provided on the surface of the fermentation tank 1. A negative pressure pump 4 is fixedly arranged on the outer wall of the fermentation tank 1 and on the side opposite to the feed pipe 2. A vacuum hose 5 is arranged between the negative pressure pump 4 and the fermentation tank 1.

[0024] Specifically, in this structure, the feed pipe 2 can place the silage and fermentation liquid to be compressed and fermented inside the fermentation tank 1. The negative pressure pump 4 can evacuate the inside of the fermentation tank 1 through the vacuum hose 5 to ensure that the inside of the fermentation tank 1 is in an anaerobic state, so as to achieve the anaerobic fermentation operation of the silage. The fermented silage can be taken out through the feeding port 3 and then fed to the feeding animals.

[0025] In a specific embodiment, as shown in Figure 3 , 4 , Figure 5, a filtering structure is provided at the connection between the vacuum hose 5 and the fermentation tank 1. The filtering structure includes a sealing plug 6. An installation hole is provided on the surface of the fermentation tank 1. The sealing plug 6 is inside the installation hole and is connected to one end of the vacuum hose 5. A through pipe 7 is connected to the bottom of the sealing plug 6. A filter screen 8 is installed inside the through pipe 7 by means of threads. Two finger holes 9 are symmetrically installed on the surface of the filter screen 8. The connection between the sealing plug 6 and the fermentation tank 1 is detachably connected by screws. Two rectangular grooves 17 are provided on the surface of the sealing plug 6.

[0026] Specifically, in this structure, during the evacuation of the silage inside the fermentation tank 1, once there are dust and impurities in the silage, it is easy for the dust and impurities to enter the inside of the vacuum hose 5, which may cause the vacuum hose 5 to be blocked after a long time. Therefore, in this structure, during the evacuation process, the filter screen 8 inside the through pipe 7 can block the dust and impurities in the silage to prevent the phenomenon that the vacuum hose 5 is blocked due to dust entering the inside of the vacuum hose 5.

[0027] The operator can remove the screw at the connection between the sealing plug 6 and the fermentation tank 1, lift the sealing plug 6 upward through the rectangular groove 17, so that the sealing plug 6 drives the through pipe 7 to extend out of the installation hole. The operator inserts two fingers into the finger holes 9 opened on the filter screen 8 and rotates the filter screen 8, so that the filter screen 8 rotates in a threaded manner with the through pipe 7, and the filter screen 8 can be separated from the inside of the through pipe 7, and then the filter screen 8 can be cleaned and replaced.

[0028] In a specific embodiment, as shown in Figure 1 , the feed pipe 2 is inclined and installed on the outer wall of the fermentation tank 1, and one end of the feed pipe 2 is hinged with a sealing pipe cover 10. The inner diameter of the sealing pipe cover 10 is larger than the outer diameter of the feed pipe 2.

[0029] Specifically, in this structure, the inclined feed pipe 2 makes it easy for the material to enter the inside of the fermentation tank 1. The sealing pipe cover 10 can seal the feed pipe 2 to prevent external air from entering the inside of the fermentation tank 1, thereby affecting the fermentation of the feed.

[0030] In a specific embodiment, as shown in Figure 1As shown, a sealing door 11 is installed inside the material taking port 3 through a hinge, and a pulling groove 12 is formed on the surface of the sealing door 11.

[0031] Specifically, in this structure, the sealing door 11 hinged and installed inside the material taking port 3 can be opened and closed. When the sealing door 11 is opened, the fully fermented feed can be taken out, and after the sealing door 11 is closed, the material taking port 3 can be sealed to prevent air from entering the inside of the fermentation tank 1, ensuring that the inside of the fermentation tank 1 is in a vacuum state.

[0032] In a specific embodiment, as shown in the appendix Figure 1 、 2 As shown, a cylinder 13 is arranged at the top of the fermentation tank 1. The output end of the cylinder 13 is provided with a pressing plate 14. A rubber scraping strip 15 is sleeved on the outer wall of the pressing plate 14. A plurality of hollow holes 16 are formed on the surface of the pressing plate 14. The cylinder 13 is fixedly installed at the top of the fermentation tank 1, and the output end of the cylinder 13 extends into the inside of the fermentation tank 1 and is connected to the surface of the pressing plate 14. The outer wall of the rubber scraping strip 15 is attached to the inner wall of the fermentation tank 1.

[0033] Specifically, in this structure, after the silage feed is inside the fermentation tank 1, the cylinder 13 drives the pressing plate 14 to extend downward to compress the silage feed inside the fermentation tank 1, which can effectively reduce the contamination of the silage feed by aerobic bacteria. Moreover, during the downward extension of the pressing plate 14, the rubber scraping strip 15 can be driven to scrape along the inner wall of the fermentation tank 1, and the silage feed attached to the inner wall of the fermentation tank 1 can be scraped off to reduce feed waste.

[0034] The working principle of the present utility model:

[0035] When the above structure is specifically used, first, the feed pipe 2 conveys the silage feed and the fermentation liquid to be fermented into the inside of the fermentation tank 1, and the sealing pipe cap 10 is closed. The cylinder 13 drives the pressing plate 14 to extend downward to compress the silage feed, further squeezing the air inside the silage feed to prevent aerobic bacteria from contaminating the silage feed. The rubber scraping strip 15 outside the pressing plate 14 can scrape off the silage feed attached to the inner wall of the fermentation tank 1 to reduce waste;

[0036] At this time, the negative pressure pump 4 is started to evacuate the inside of the fermentation tank 1 by using the vacuum hose 5. During the evacuation process, the filter screen 8 inside the through pipe 7 can block the dust and impurities inside the silage feed to prevent the dust and impurities from entering the inside of the vacuum hose 5 and causing blockage for a long time, affecting the evacuation effect;

[0037] The operator can remove the screw at the sealing plug 6 and the fermentation tank 1, lift the sealing plug 6 upward through the rectangular groove 17, so that the sealing plug 6 drives the through pipe 7 to extend out from the inside of the mounting hole, put two fingers into the finger holes 9 opened in the filter screen 8, and rotate the filter screen 8, so that the filter screen 8 and the through pipe 7 are rotated threadedly, and the filter screen 8 can be separated from the inside of the through pipe 7, and then the filter screen 8 can be cleaned and replaced;

[0038] Similarly, during installation, the filter screen 8 is threadedly installed inside the through pipe 7, and the through pipe 7 is extended into the fermentation tank 1 through the mounting hole, and finally the sealing plug 6 and the fermentation tank 1 are connected and sealed by screws.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
