Description

Technical Field

[0001] The present invention relates to the field of animal feed production, and in particular to intelligent animal feed production equipment. Background Art

[0002] Silage is made by crushing fresh grass, straw and other plant feed and putting them into fermentation barrels for fermentation. The fermented silage retains the original nutrients, improves palatability and extends the shelf life. It is a commonly used method of feed production.

[0003] Silage fermented in the fermentation barrel can be used directly for livestock feeding. Usually, when using silage, farms will only take an appropriate amount of feed from the fermentation barrel for feeding each time, and the remaining feed will continue to be stored in the fermentation barrel, extending the shelf life while continuing to ferment. When part of the feed in the fermentation barrel is taken out, a cavity will appear in the fermentation barrel. Although the fermentation barrel will be resealed with the barrel cover after each feed is taken, outside air has entered the cavity. This part of air will affect the anaerobic fermentation environment and is not conducive to the fermentation and preservation of the feed; and as the number of times the feed is taken increases, the larger the cavity, the more air content, and thus the less feed in the fermentation barrel, the shelf life will be greatly shortened.

[0011] More preferably, a pull ring is provided on the upper side of the closing block.

[0012] More preferably, one end of the scraper close to the inner wall of the fermentation barrel is made of rubber material and contacts the inner wall of the fermentation barrel; a groove for accommodating the rubber end of the scraper is correspondingly provided on the sealing member.

[0013] More preferably, a collecting assembly is also included, which includes a fixed ring, a slip ring, a one-way valve and a collecting bag; a plurality of fixed rings are fixedly connected to the barrel cover; each fixed ring corresponds to an exhaust port; a slip ring is rotatably connected to each fixed ring; the inner diameter of the slip ring is larger than the diameter of the exhaust port; two third limit blocks are fixedly connected to each fixed ring; a plurality of paddles are fixedly connected to the upper side of the slip ring; two groups of vertically distributed one-way valves are installed on each fixed ring; one group of one-way valves is connected to the outside; each one-way valve of the other group is connected to a collecting bag for collecting fermentation gas; two connecting holes are provided on each slip ring; the connecting hole on the same slip ring is connected to the corresponding group of one-way valves; and scale lines are provided on the inner wall of the fermentation barrel.

[0016] The bracket formed by the connecting frame and the columnar roller prevents the barrel cover from deflecting when it moves down, causing the seal to not contact the inner wall of the fermentation barrel and lose its sealing performance;

[0017] When the barrel cover moves downward, it rotates and drives the scraper to scrape the surface of the remaining feed flat, so as to avoid pits on the surface of the remaining feed. Air is retained in the pits, which causes the feed on the surface of the pits to deteriorate. The deteriorated feed then infects the rest of the feed below, thus affecting the storage of all the remaining feed.

[0018] The fermentation gas is collected by the collecting component to prevent the fermentation gas from rushing out when the user opens the fermentation barrel and being inhaled by the user, which endangers the user's health. In addition, the fermentation gas has a strong irritating odor and is likely to cause discomfort to the user on the spot.

[0019] By controlling the sealing member to shrink and not contact the inner wall of the fermentation barrel, the sealing member does not generate resistance when the user lifts the connecting frame and the barrel cover, making it convenient for the user to bend over and reach into the fermentation barrel to lift the connecting frame and the barrel cover.

DETAILED DESCRIPTION

[0032] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0033] Example 1

[0034] like Figure 1-Figure 8 As shown, an intelligent animal feed production device includes a fermentation barrel 1 and a mounting ring 2; the fermentation barrel 1 is made of plastic; the mounting ring 2 is connected to the fermentation barrel 1; the inner diameter of the mounting ring 2 is the same as the inner diameter of the fermentation barrel 1; and a plurality of locks for locking the mounting ring 2 are installed on the fermentation barrel 1;

[0035] It also includes a connecting frame 3, a barrel cover 4, a closing block 5, a cylindrical roller 6, an intelligent thermometer 8 and a sealing member 41; two groups of first limit blocks 2001 are fixedly connected to the inner side of the mounting ring 2; two U-shaped second limit blocks 2002 are slidably connected to the mounting ring 2; the U-shaped opening of the second limit block 2002 faces the center of the mounting ring 2; a group of first limit blocks 2001 corresponds to a second limit block 2002 in upper and lower correspondence; a connecting frame 3 is provided on the mounting ring 2; the connecting frame 3 is composed of an outer connecting ring 3001, four connecting rods 3002 and an inner connecting ring 3003; the outer connecting ring 3001 is inserted into the first limit blocks 2001 corresponding to the upper and lower parts. between the limit block 2001 and the second limit block 2002; the barrel cover 4 is connected to the lower side of the inner connecting ring 3003; two exhaust ports 4001 are provided on the barrel cover 4; a pair of slide bars 4002 are arranged beside each exhaust port 4001; an elastic member 4003 is fixedly connected to each slide bar 4002; a closing block 5 is commonly connected to each pair of slide bars 4002 in a damping sliding manner; the closing block 5 is fixedly connected to the corresponding elastic member 4003; eight columnar rollers 6 are arranged in a circular array on the outer connecting ring 3001; an intelligent thermometer 8 is installed on the upper side of the barrel cover 4; the probe of the intelligent thermometer 8 passes downward through the barrel cover 4.

[0036] It also includes a scraping assembly, which includes a connecting shaft 21 and a scraper 22; the connecting shaft 21 is fixedly connected to the center of the upper surface of the barrel cover 4; the connecting shaft 21 is rotatably connected to the inner connecting ring 3003; the hand wheel 2101 is bolted to the upper side of the connecting shaft 21; the middle of the connecting shaft 21 is fixedly connected to a limit plate 2102; the lower side of the limit plate 2102 is in contact with the upper side of the inner connecting ring 3003, and then the barrel cover 4, the connecting shaft 21 and the inner connecting ring 3003 form upper and lower restrictions on each other; four scrapers 22 are rotatably connected to the lower side of the barrel cover 4 through a torsion spring; the scrapers 22 are arranged at an angle; a group of storage grooves 4004 adapted to the scrapers 22 are opened on the lower side of the barrel cover 4.

[0037] It also includes balls 7; a number of balls 7 are installed on the lower side of the outer connecting ring 3001 through a support rod; the balls 7 are in contact with the upper surface of the barrel cover 4 to increase the stability between the connecting frame 3 and the barrel cover 4, while reducing the friction with the upper surface of the barrel cover 4.

[0038] A clamping ring is arranged on the barrel edge of the fermentation barrel 1; a clamping groove matched with the clamping ring is arranged on the lower side of the mounting ring 2 to ensure the stability of the connection between the mounting ring 2 and the fermentation barrel 1.

[0039] The connecting rod 3002 is provided with a columnar gripping portion, which facilitates the user to grip the connecting rod 3002 to drive related parts.

[0040] A turning arrow mark is provided on the upper surface of the barrel cover 4, so that the user can intuitively understand the rotation direction of the barrel cover 4, and it is convenient to perform the rotation operation on the barrel cover 4.

[0041] A pull ring is provided on the upper side of the closing block 5 to facilitate the user to pull the closing block 5 .

[0042] The scraper 22 is made of rubber at one end close to the inner wall of the fermentation barrel 1 and contacts the inner wall of the fermentation barrel 1. When the barrel cover 4 drives the scraper 22 to rotate, the feed remaining on the inner wall of the fermentation barrel 1 can be scraped off; a groove for accommodating the rubber end of the scraper 22 is correspondingly opened on the sealing member 41.

[0043] In the initial state of the present invention, the U-shaped second limit block 2002 is located at Figure 5 In the initial position shown, there is a gap between the first limit block 2001 fixed to the inner side of the mounting ring 2 and the corresponding second limit block 2002 below. By restricting the external connecting ring 3001 in the gap, the connecting frame 3 and its connecting parts are locked and fixed to the mounting ring 2 to form a complete closing cover for closing the fermentation barrel 1.

[0044] When the feed is fermented, the fermentation barrel 1 is in an open state. The user puts the unfermented feed into the fermentation barrel 1 and fills it up. Then, the snap ring on the fermentation barrel 1 is aligned with the snap groove of the mounting ring 2. The mounting ring 2, the connecting frame 3 and the barrel cover 4 are covered on the fermentation barrel 1 to seal the fermentation barrel 1. The mounting ring 2 is locked and fixed by the lock on the fermentation barrel 1, thereby sealing and fermenting the feed. During the fermentation process, the temperature in the fermentation barrel 1 is monitored in real time by the intelligent thermometer 8 to prevent temperature changes from affecting the fermentation environment. The intelligent thermometer 8 is powered by a battery.

[0045] When the feed is fermented and needs to be taken, the user opens the lock on the fermentation barrel 1 to release the lock on the mounting ring 2, then holds the connecting rod 3002, removes the closing cover composed of the mounting ring 2, the connecting frame 3 and the barrel cover 4 from the fermentation barrel 1, and takes the feed; after the feed is taken, a cavity appears in the fermentation barrel 1. Although the fermentation barrel 1 is resealed through the closing cover after each feed is taken, the outside air has entered the cavity, which will affect the anaerobic fermentation environment and is not conducive to the fermentation and preservation of the remaining feed; and as the number of times the feed is taken increases, the larger the cavity is, the more air content is, and the fermentation barrel 1 is The less feed there is, the shorter the shelf life will be. After the user re-fixes the closing cover on the fermentation barrel 1, he manually pulls the second limit block 2002 away from the center of the mounting ring 2, and the second limit block 2002 is out of contact with the lower side of the outer connecting ring 3001. Then the user pulls up the closing block 5 through the pull ring, and the closing block 5 compresses the corresponding elastic member 4003, thereby opening the exhaust port 4001. The closing block 5 and the slide bar 4002 are damped sliding. After the closing block 5 is pulled up, the elastic member 4003 stretches to slowly push the closing block 5 downward to close the exhaust port 4001. Then the user holds the closing block 5 and pulls up the elastic member 4003 to slowly push the closing block 5 downward to close the exhaust port 4001. Holding the connecting rod 3002, the connecting frame 3 is pushed downward, and the connecting frame 3 squeezes and pushes the barrel cover 4 downward. During the downward movement of the barrel cover 4, the air in the lower cavity is squeezed, and the air is discharged upward to the outside through the exhaust port 4001. During the exhaust of the lower side of the barrel cover 4 through the exhaust port 4001, the closing block 5 is pushed upward to prevent it from moving downward to close the exhaust port 4001, until the lower side of the barrel cover 4 contacts the surface of the remaining feed and cannot move further downward, the air in the cavity is completely discharged, and at the same time, the cavity between the barrel cover 4 and the remaining feed disappears, and then the closing block 5 is re-closed under the extension and push of the elastic member 4003. The opening 4001 enables the barrel cover 4 to isolate the remaining feed from the outside world, and to seal and ferment the remaining feed, thereby preventing outside air from entering the cavity created by taking out some of the feed, affecting the anaerobic fermentation environment, and being detrimental to the fermentation and preservation of the remaining feed; when the remaining feed is subsequently fermented and preserved, the barrel cover 4 remains in a position pressed on the remaining feed. When the feed needs to be taken out, the user first pulls up the closing block 5 to open the exhaust opening 4001, so that the air pressure above and below the barrel cover 4 is the same, and then pulls up the connecting frame 3 and the barrel cover 4 and fixes them to the mounting ring 2, and removes them from the fermentation barrel 1 together, and then takes out the feed.

[0046] Furthermore, when the connecting frame 3 and the barrel cover 4 move downward along the inner wall of the fermentation barrel 1, the cylindrical roller 6 contacts and rolls with the inner wall of the fermentation barrel 1, thereby forming support between the connecting frame 3 and the fermentation barrel 1. Then, the bracket formed by the connecting frame 3 and the cylindrical roller 6 is located above the barrel cover 4, thereby preventing the barrel cover 4 from deflecting when moving downward, causing the seal 41 to not contact with the inner wall of the fermentation barrel 1 and lose its sealing performance.

[0047] After each feed is taken, pits appear on the surface of the remaining feed due to digging with tools. When the pits are deep, they contain some air. After the barrel cover 4 is pressed down and contacts the raised part of the surface of the remaining feed, it cannot move down further. The air in the pits is located on the lower side of the barrel cover 4. During the subsequent fermentation and storage process, it contacts the surface of the feed in the pits, which can easily cause the surface feed to deteriorate. The deteriorated feed then infects the rest of the feed on the lower side, thereby affecting the storage of all the remaining feed.

[0048] like Figure 7 As shown, under the action of the torsion spring, each scraper 22 is initially inclined. When the user squeezes the connecting frame 3 and the barrel cover 4 downward to perform the exhaust operation, one hand holds the connecting rod 3002 to push the connecting frame 3 and the barrel cover 4 downward, and the other hand holds the hand wheel 2101 and rotates it in the direction of the steering arrow on the barrel cover 4. The hand wheel 2101 drives the connecting shaft 21 to rotate, and the connecting shaft 21 is rotatably connected with the inner connecting ring 3003, thereby driving the barrel cover 4 to rotate relative to the connecting frame 3. During the downward movement of the barrel cover 4 and contact with the surface of the remaining feed, the downward inclined surface of the scraper 22 first contacts with the remaining feed, and in the process of being driven to rotate by the barrel cover 4, the scraper 22 scrapes the uneven surface of the remaining feed flat, avoiding pits on the surface of the remaining feed, and residual air in the pits, resulting in the deterioration of the feed on the surface of the pit, and the deteriorated feed then infects the remaining feed on the lower side, thereby affecting the storage of all the remaining feed.

[0049] As the bucket cover 4 moves downward and the scraper 22 scrapes the surface of the remaining feed, as the surface of the remaining feed is gradually scraped flat, the reaction force applied by the feed to the downward inclined surface of the scraper 22 will squeeze the scraper 22 to flip it over, and the scraper 22 will synchronously twist the torsion spring, and the scraper 22 will flip over and retract into the corresponding storage groove 4004 until the surface of the remaining feed is completely smoothed. The scraper 22 also flips over to become horizontal and is completely stored in the corresponding storage groove 4004, cooperating with the lower side of the bucket cover 4 to form a complete plane, and then the bucket cover 4 and the scraper 22 are pressed flat on the surface of the remaining feed to avoid the formation of residual air in the cavity.

[0050] Furthermore, during the rotation of the barrel cover 4, the balls 7 come into contact with the upper surface of the barrel cover 4, thereby increasing the stability between the connecting frame 3 and the barrel cover 4 and reducing the friction with the upper surface of the barrel cover 4.

[0051] Example 2

[0052] On the basis of Example 1, Figure 2 and Figure 9-11As shown, it also includes a collecting component, which includes a fixing ring 31, a sliding ring 32, a one-way valve 33 and a collecting bag 34; two fixing rings 31 are fixedly connected to the barrel cover 4; each fixing ring 31 corresponds to an exhaust port 4001; a sliding ring 32 is rotatably connected in each fixing ring 31; the inner diameter of the sliding ring 32 is larger than the diameter of the exhaust port 4001; two third limit blocks 3101 are fixedly connected to each fixing ring 31; two paddles 3202 are fixedly connected to the upper side of the sliding ring 32; two groups of vertically distributed one-way valves 33 are installed on each fixing ring 31; one group of one-way valves 33 is connected to the outside; each one-way valve 33 of the other group is connected to a collecting bag 34; two connecting holes 3201 are provided on each sliding ring 32; the connecting hole 3201 on the same sliding ring 32 is connected to the corresponding group of one-way valves 33; and scale lines are provided on the inner wall of the fermentation barrel 1.

[0053] For the sake of distinction, a group of one-way valves 33 connected to the outside world is referred to as the first group of one-way valves 33; a group of one-way valves 33 connected to the collection bag 34 is referred to as the second group of one-way valves 33; in the initial state, the connecting hole 3201 is connected to the first group of one-way valves 33. Based on this embodiment, the air exhausted from the exhaust port 4001 in Embodiment 1 is discharged to the outside world through the first group of one-way valves 33.

[0054] During the feed fermentation process, various fermentation gases are generated, most of which have a strong pungent odor. When the barrel cover 4 is not opened for a long time, the fermentation gas concentration in the fermentation barrel 1 increases. When the barrel cover 4 is opened subsequently, the fermentation gas rushes out and is inhaled by the user, which can easily cause discomfort to the user on the spot.

[0055] When fermentation gas is continuously generated in the fermentation barrel 1, the barrel cover 4 originally pressed on the surface of the feed will be pushed by the gas pressure accumulated by the fermentation gas and move upward along the inner wall of the fermentation barrel 1, and the fermentation gas will continue to accumulate in the cavity on the lower side of the barrel cover 4. Due to the sealing of the sealing member 41, the cavity is not connected to the outside world. Before the user opens the barrel cover 4, the user observes the height of the barrel cover 4 through the scale lines on the inner wall of the fermentation barrel 1 to see whether it is consistent with the height when it was closed last time. If the height is consistent, it means that there is no gas accumulation and the barrel cover 4 can be opened directly. However, if it is higher than the height of the last closure, it means that fermentation gas has accumulated on the lower side of the barrel cover 4. At this time, based on the view from top to bottom, the user manually turns the paddle 3202 counterclockwise by 90 degrees, and the paddle 3202 drives the slip ring 32 to rotate until the paddle 3202 contacts the corresponding third limit block 3101 and cannot continue to rotate, so that the connecting hole 3201 originally connected to the first group of one-way valves 33 is changed to be connected to the second group of one-way valves 33, and is also connected to the collecting bag 34. The user then pulls up the closing block 5 through the pull ring to open the exhaust port 4001, then holds the connecting rod 3002 to push the connecting frame 3 and the barrel cover 4 downward, the barrel cover 4 compresses the fermentation gas on the lower side, so that it is discharged upward through the exhaust port 4001, and the fermentation gas enters the collecting bag 34 through the connecting hole 3201 and the second set of one-way valves 33 to be collected and not released to the outside, so as to prevent the fermentation gas from rushing out and being inhaled by the user, which endangers the user's health. In addition, the fermentation gas has a strong irritating odor and is easy to cause discomfort to the user on the spot; the user pushes the connecting frame 3 and the barrel cover 4 downward until the lower side of the barrel cover 4 contacts the feed and cannot move further downward. At this time, all the fermentation gas has been discharged into the collecting bag 34, and then the user moves the connecting frame 3 and the barrel cover 4 upward again, and connects the connecting frame 3 with the mounting ring 2 through the first limit block 2001 and the second limit block 2002, and then removes the mounting ring 2, the connecting frame 3 and the barrel cover 4 from the fermentation barrel 1 to take the feed.

[0056] Furthermore, when the barrel cover 4 is not opened for a long time, the pressure of the fermentation gas pushes the connecting frame 3 and the barrel cover 4 to move upward until the outer connecting ring 3001 contacts the lower side of the first limit block 2001, and the connecting frame 3 and the barrel cover 4 cannot move upward any further, and the fermentation gas in the cavity under the barrel cover 4 will continue to accumulate, causing the cavity pressure to increase. The fermentation barrel 1 is usually made of plastic, and excessive pressure can easily cause the fermentation barrel 1 to deform. Therefore, when the fermentation gas in the cavity under the barrel cover 4 accumulates too much pressure, it will push the closing block 5 upward, and the closing block 5 will simultaneously compress the elastic member 4003, so that the exhaust gas The port 4001 is opened to release the pressure, and at this time it is connected with the first group of one-way valves 33 and the connecting hole 3201, and the fermentation gas is discharged from the exhaust port 4001 through the first group of one-way valves 33. After that, when the pressure in the cavity on the lower side of the barrel cover 4 is the same as the external pressure, no upward thrust is generated on the closing block 5, and the elastic member 4003 stretches to push the closing block 5 downward to reset it, and re-close the exhaust port 4001, thereby automatically releasing the pressure in the cavity on the lower side of the barrel cover 4, avoiding deformation of the fermentation barrel 1 caused by excessive pressure in the cavity, and preventing external air from entering the cavity and affecting the anaerobic fermentation environment in the cavity.

[0057] Example 3

[0058] On the basis of Example 2, Figure 3 , Figure 5 and Fig. 9 As shown, it also includes a micro air pump 42 and an air supply pipe 43; the sealing member 41 is a rubber air bag; at least one micro air pump 42 is bolted to the barrel cover 4; each micro air pump 42 outlet is connected to an air supply pipe 43; the air supply pipe 43 is connected to the sealing member 41, and the size of the sealing member 41 is changed through air supply and air suction by the micro air pump 42.

[0059] When the height of the remaining feed is close to the bottom of the fermentation barrel 1, the user pushes the connecting frame 3 and the barrel cover 4 downwards to the corresponding height. When the barrel cover 4 needs to be opened again to take the feed, the connecting frame 3 and the barrel cover 4 are located deep and far from the barrel mouth of the fermentation barrel 1, and the user needs to bend down and put the body into the fermentation barrel 1 to lift the connecting frame 3 and the barrel cover 4. However, in order to ensure the sealing, the sealing member 41 is in close contact with the inner wall of the fermentation barrel 1, and the friction is large, so the user encounters great resistance when lifting the connecting frame 3 and the barrel cover 4 from the bottom of the fermentation barrel 1, and the posture of the user putting the body into the fermentation barrel 1 is inconvenient to apply force, making it difficult to lift the connecting frame 3 and the barrel cover 4.

[0060] When the connecting frame 3 and the barrel cover 4 are close to the bottom of the fermentation barrel 1 and the user needs to lift the connecting frame 3 and the barrel cover 4, the micro air pump 42 is controlled to work, and the micro air pump 42 extracts the air inside the seal 41 through the air supply pipe 43, so that the seal 41 shrinks and does not contact the inner wall of the fermentation barrel 1. Then, when the user lifts the connecting frame 3 and the barrel cover 4, the seal 41 does not generate resistance, which is convenient for the user to bend over and put the body into the fermentation barrel 1 to lift the connecting frame 3 and the barrel cover 4; when the user needs to re-seal the fermentation barrel 1, the micro air pump 42 is controlled to work to supply air to the seal 41, so that the seal 41 expands to the same diameter as the inner diameter of the fermentation barrel 1, and the sealing effect is normally achieved.

[0061] It should be noted that the micro air pump 42 is powered by a battery installed on the barrel cover 4.
