Description

Technical Field

[0001] The present invention relates to the field of animal feed production, and particularly to an intelligent production device for animal feed. Background Art

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

[0003] The silage feed fermented in the fermentation barrel can be directly used for livestock feeding. Usually, when a farm uses silage feed, only an appropriate amount of feed is taken from the fermentation barrel for feeding each time, and the remaining feed will continue to be stored in the fermentation barrel, which can extend the shelf life and still continue to ferment. When a part of the feed in the fermentation barrel is taken away, a cavity appears in the fermentation barrel. Although the fermentation barrel is re-sealed through the barrel lid each time the feed is taken, external air has entered the cavity. This part of the air will affect the anaerobic fermentation environment and is not conducive to the fermentation and preservation of the feed. Moreover, with the increase in the number of times of taking, the cavity becomes larger, the air content increases, and then the feed in the fermentation barrel becomes less, and the shelf life will also be greatly shortened.

[0007] More preferably, it further includes ball bearings; several ball bearings are installed on the lower side of the outer connecting ring through support rods; the ball bearings contact the upper surface of the bucket cover.

[0008] More preferably, a clamping ring is arranged on the edge of the fermentation bucket; a clamping groove adapted to the clamping ring is opened on the lower side of the mounting ring.

[0009] More preferably, a columnar holding part is arranged on the connecting rod.

[0010] More preferably, a steering arrow mark is arranged on the upper surface of the bucket cover.

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

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

[0013] More preferably, it further includes a collection component. The collection component includes a fixed ring, a sliding ring, a one-way valve and a collection bag; several fixed rings are fixedly connected to the bucket cover; each fixed ring corresponds to an exhaust port; a sliding ring is rotatably connected in each fixed ring; the inner diameter of the sliding ring is larger than the diameter of the exhaust port; two third limiting blocks are fixedly connected to each fixed ring; several sliders are fixedly connected to the upper side of the sliding ring; two groups of one-way valves distributed vertically are installed on each fixed ring; one group of one-way valves is communicated with the outside; each one-way valve of the other group is communicated with a collection bag for collecting fermentation gas; two connecting holes are opened on each sliding ring; the connecting holes on the same sliding ring are communicated with the corresponding group of one-way valves; a scale line is arranged on the inner wall of the fermentation bucket.

At the same time, the cavity between the bucket lid and the remaining feed also disappears, and the sealing block reseals the exhaust port, so that the bucket lid isolates the remaining feed from the outside world, and the remaining feed is sealed and fermented for preservation. Thus, after taking part of the feed, it can avoid the outside air entering the cavity formed by taking away the feed, affecting the anaerobic fermentation environment and being unfavorable to the fermentation and preservation of the remaining feed;

[0016] The bracket formed by the connecting frame and the columnar roller avoids the deflection of the bucket lid when it moves downward, resulting in the sealing member not contacting the inner wall of the fermentation barrel and losing the sealing property;

[0017] When the bucket lid moves downward, it rotates and drives the scraper to scrape the surface of the remaining feed flat, avoiding the appearance of pits on the surface of the remaining feed. The air remains in the pits, resulting in the deterioration of the feed on the surface layer in the pits, and the deteriorated feed infects the remaining feed below, thereby affecting the storage of all the remaining feed;

[0018] The fermentation gas is collected by the collection component, avoiding that when the user opens the fermentation barrel, the fermentation gas rushes outwards and is inhaled into the body by the user, endangering the health of the user, and the fermentation gas has a strong pungent smell and is likely to cause discomfort to the user on the spot;

[0019] By controlling the contraction of the sealing member so that it does not contact the inner wall of the fermentation barrel, when the user lifts the connecting frame and the bucket lid, the sealing member does not generate resistance, facilitating the user to bend down and reach into the fermentation barrel to lift the connecting frame and the bucket lid.

Detailed implementation manners

[0032] The following is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention accordingly.

[0033] Embodiment 1

[0034] As Figures 1-8 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; a plurality of latches for locking the mounting ring 2 are installed on the fermentation barrel 1;

[0035] It also includes a connecting frame 3, a bucket cover 4, a closing block 5, columnar rollers 6, an intelligent thermometer 8 and a seal 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; One group of first limit blocks 2001 corresponds to one second limit block 2002 vertically; A connecting frame 3 is arranged 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 between the vertically corresponding first limit block 2001 and second limit block 2002; The lower side of the inner connecting ring 3003 is connected with a bucket cover 4; Two exhaust ports 4001 are opened on the bucket cover 4; A pair of sliding rods 4002 are arranged beside each exhaust port 4001; An elastic member 4003 is fixedly connected to each sliding rod 4002; A closing block 5 is slidably connected to each pair of sliding rods 4002 in a damping 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 bucket cover 4; The probe of the intelligent thermometer 8 passes downward through the bucket cover 4.

[0036] It also includes a scraping component, and the scraping component includes a connecting shaft 21 and a scraping plate 22; The connecting shaft 21 is fixedly connected to the center of the upper surface of the bucket cover 4; The connecting shaft 21 is rotatably connected to the inner connecting ring 3003; A handwheel 2101 is bolted to the upper side of the connecting shaft 21; A limiting plate 2102 is fixedly connected to the middle of the connecting shaft 21; The lower side of the limiting plate 2102 contacts the upper side of the inner connecting ring 3003, so that the bucket cover 4, the connecting shaft 21 and the inner connecting ring 3003 form upper and lower restrictions on each other; Four scraping plates 22 are rotatably connected to the lower side of the bucket cover 4 through torsion springs; The scraping plates 22 are arranged obliquely; A group of storage grooves 4004 adapted to the scraping plates 22 are opened on the lower side of the bucket 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 support rods; The balls 7 contact the upper surface of the bucket cover 4, which is used to increase the stability between the connecting frame 3 and the bucket cover 4 and at the same time reduce the friction with the upper surface of the bucket cover 4.

[0038] A clamping ring is arranged on the rim of the fermentation barrel 1; A clamping groove adapted to the clamping ring is opened 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] Columnar gripping parts are arranged on the connecting rods 3002; It is convenient for the user to grip the connecting rods 3002 to drive related parts.

[0040] A steering arrow mark is arranged on the upper surface of the bucket cover 4; It allows the user to intuitively understand the rotation direction of the bucket cover 4 and is convenient for rotating the bucket cover 4.

[0041] A pull ring is provided on the upper side of the closing block 5; it is convenient for the user to lift the closing block 5.

[0042] One end of the scraping plate 22 close to the inner wall of the fermentation barrel 1 is made of rubber and is in contact with the inner wall of the fermentation barrel 1. When the barrel cover 4 drives the scraping plate 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 scraping plate 22 is correspondingly formed on the sealing member 41.

[0043] In the initial state of the present invention, the U-shaped second limiting block 2002 is located at the Figure 5 shown initial position. There is a gap between the first limiting block 2001 fixedly connected to the inside of the mounting ring 2 and the corresponding second limiting block 2002 below. By restricting the outer connecting ring 3001 in this 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 fermenting the feed, the fermentation barrel 1 is in an open state. The user loads the unfermented feed into the fermentation barrel 1 and fills it up. Then, the clamping ring on the fermentation barrel 1 is aligned with the clamping groove of the mounting ring 2, and 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 through the buckle on the fermentation barrel 1, thereby sealing and fermenting the feed. During the fermentation process, the temperature inside the fermentation barrel 1 is monitored in real time by the intelligent temperature measuring instrument 8 to avoid the influence of temperature changes on the fermentation environment. The intelligent temperature measuring instrument 8 is powered by a storage battery.

[0045] When the feed fermentation is completed and it is necessary to take the feed, the user unlocks the locking of the mounting ring 2 by opening the buckle on the fermentation barrel 1. Then, hold the connecting rod 3002 and remove the closed cover composed of the mounting ring 2, the connecting frame 3 and the barrel cover 4 from the fermentation barrel 1 to take the feed. After taking the feed, there is a cavity in the fermentation barrel 1. Although the fermentation barrel 1 is re-sealed through the closed cover every time the feed is taken, the outside air has entered the cavity. This part of the air will affect the anaerobic fermentation environment and is not conducive to the fermentation and preservation of the remaining feed. Moreover, the more times the feed is taken, the larger the cavity is, the more air content there is, and then the less feed there is in the fermentation barrel 1, and the shelf life will also be greatly shortened. When the user re-fixes the closed cover on the fermentation barrel 1, manually pull the second limit block 2002 to make it away from the center of the mounting ring 2. The second limit block 2002 is separated from the lower side of the outer connecting ring 3001. Then, the user pulls up the closing block 5 through the pull ring. The closing block 5 compresses the corresponding elastic member 4003, thereby opening the exhaust port 4001. The closing block 5 and the slide rod 4002 are in a damped sliding state. After the closing block 5 is pulled up, the elastic member 4003 will slowly push the closing block 5 downward to close the exhaust port 4001. Then, the user holds the connecting rod 3002 and pushes the connecting frame 3 downward. 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. When the air under the barrel cover 4 is discharged through the exhaust port 4001, it pushes the closing block 5 upward so that it does not move 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 downward anymore, the air in the cavity is completely discharged. At the same time, the cavity between the barrel cover 4 and the remaining feed also disappears. Then, the closing block 5 is re-closed the exhaust port 4001 under the pushing of the elastic member 4003, so that the barrel cover 4 isolates the remaining feed from the outside and seals and ferments the remaining feed for preservation. Thus, it is avoided that after taking some feed, the outside air enters the cavity formed by taking away the feed, affecting the anaerobic fermentation environment and being not conducive to the fermentation and preservation of the remaining feed. During the subsequent fermentation and preservation of the remaining feed, the barrel cover 4 remains pressed on the remaining feed. When it is necessary to take the feed, the user first pulls up the closing block 5 to open the exhaust port 4001 to make the air pressure above and below the barrel cover 4 the same. Then, pull up the connecting frame 3 and the barrel cover 4 and fix them to the mounting ring 2, and remove them from the fermentation barrel 1 together, and then take the feed.

[0046] Further, when the connecting frame 3 and the barrel cover 4 move downward along the inner wall of the fermentation barrel 1, the columnar roller 6 contacts and rolls on the inner wall of the fermentation barrel 1, forming a support between the connecting frame 3 and the fermentation barrel 1. Then, the support formed by the connecting frame 3 and the columnar roller 6 is located above the barrel cover 4, avoiding the barrel cover 4 from deflecting when moving downward, resulting in the sealing member 41 not contacting the inner wall of the fermentation barrel 1 and losing the sealing property.

[0047] After each time the feed is taken, due to the use of a tool to dig, pits appear on the surface of the remaining feed. When the pits are relatively deep, there is some air in the pits. After the bucket lid 4 is pressed down and contacts the raised part of the surface of the remaining feed, it cannot continue to move down. The air in the pits is located below the bucket lid 4 and contacts the surface of the feed in the pits during the subsequent fermentation and storage process, which is likely to cause the feed on the surface layer to deteriorate. The deteriorated feed then infects the remaining feed below, thereby affecting the storage of all the remaining feed.

[0048] As Figure 7 shown, under the action of the torsion spring, each scraper 22 is initially inclined. When the user presses down the connecting frame 3 and the bucket lid 4 for exhaust operation, one hand holds the connecting rod 3002 and pushes down the connecting frame 3 and the bucket lid 4, and the other hand holds the handwheel 2101 and rotates it in the direction of the steering arrow mark on the bucket lid 4. The handwheel 2101 drives the connecting shaft 21 to rotate. The connecting shaft 21 is rotationally connected to the inner connecting ring 3003, thereby driving the bucket lid 4 to rotate relative to the connecting frame 3. During the process of the bucket lid 4 moving down and contacting the surface of the remaining feed, the downward inclined surface of the scraper 22 first contacts the remaining feed. During the rotation driven by the bucket lid 4, the scraper 22 scrapes the uneven surface of the remaining feed flat, avoiding the appearance of pits on the surface of the remaining feed and residual air in the pits, which may cause the feed on the surface layer in the pits to deteriorate. The deteriorated feed then infects the remaining feed below, thereby affecting the storage of all the remaining feed.

[0049] During the process of the bucket lid 4 moving down and the scraper 22 scraping the surface of the remaining feed flat, as the surface of the remaining feed is gradually scraped flat, the reaction force exerted by the feed on the downward inclined surface of the scraper 22 will squeeze the scraper 22 to make it flip. The scraper 22 synchronously twists the torsion spring, and the scraper 22 flips and retracts into the corresponding storage groove 4004 until the surface of the remaining feed is completely smoothed, and the scraper 22 also flips into a horizontal state and is completely stored in the corresponding storage groove 4004, cooperating with the lower side of the bucket lid 4 to form a complete plane. Thus, the bucket lid 4 and the scraper 22 are pressed flat on the surface of the remaining feed, avoiding the residual air in the cavity.

[0050] Furthermore, during the rotation of the bucket lid 4, the contact with the upper surface of the bucket lid 4 through the ball 7 increases the stability between the connecting frame 3 and the bucket lid 4, and at the same time reduces the friction with the upper surface of the bucket lid 4.

[0051] Embodiment 2

[0052] On the basis of Embodiment 1, as Figure 2 and Figures 9-11As shown in the figure, it further includes a collection component, which includes a fixed ring 31, a sliding ring 32, a one-way valve 33, and a collection bag 34; two fixed rings 31 are fixedly connected to the bucket cover 4; each fixed ring 31 corresponds to an exhaust port 4001; a sliding ring 32 is rotatably connected inside each fixed 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 fixed ring 31; two paddles 3202 are fixedly connected to the upper side of the sliding ring 32; two sets of one-way valves 33 distributed vertically are installed on each fixed ring 31; one set of one-way valves 33 is communicated with the outside; each one-way valve 33 of the other set is communicated with a collection bag 34; two connection holes 3201 are opened on each sliding ring 32; the connection holes 3201 on the same sliding ring 32 are communicated with the corresponding set of one-way valves 33; scale lines are provided on the inner wall of the fermentation barrel 1.

[0053] For the convenience of distinction, in the following text, the set of one-way valves 33 communicated with the outside is called the first set of one-way valves 33; the set of one-way valves 33 communicated with the collection bag 34 is called the second set of one-way valves 33; in the initial state, the connection hole 3201 is communicated with the first set of one-way valves 33. On the basis of this embodiment, the air discharged from the exhaust port 4001 in Embodiment 1 is discharged to the outside through the first set of one-way valves 33.

[0054] During the feed fermentation process, various fermentation gases are generated, and most of these gases have a strong pungent smell. When the bucket cover 4 is not opened for a long time, the concentration of fermentation gases in the fermentation barrel 1 increases. When the bucket cover 4 is opened later, the fermentation gases rush outwards and are easily inhaled by the user, which can 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 air pressure accumulated by the fermentation gas and move upward along the inner wall of the fermentation barrel 1. The fermentation gas continues to accumulate in the cavity on the lower side of the barrel cover 4. Due to the sealing of the seal 41, this cavity is not connected to the outside. Before the user opens the barrel cover 4, through the scale line on the inner wall of the fermentation barrel 1, observe whether the height of the barrel cover 4 is the same as the height at the last closing. If the heights are the same, it means there is no gas accumulation and the barrel cover 4 can be directly opened. However, if it is higher than the height at the last closing, it means there is fermentation gas accumulated under the barrel cover 4. At this time, with the top-down view as the reference, the user manually turns the dial 3202 counterclockwise by 90 degrees. The dial 3202 drives the slip ring 32 to rotate until the dial 3202 contacts the corresponding third limit block 3101 and cannot rotate further, causing the connection hole 3201 originally connected to the first group of one-way valves 33 to be changed to be connected to the second group of one-way valves 33 and also to the collection bag 34. Then the user pulls up the closing block 5 through the pull ring to open the exhaust port 4001. Then hold the connecting rod 3002 and push the connecting frame 3 and the barrel cover 4 downward. The barrel cover 4 compresses the fermentation gas below it, causing it to be discharged upward through the exhaust port 4001. The fermentation gas enters the collection bag 34 through the connection hole 3201 and the second group of one-way valves 33 and is collected without escaping to the outside, preventing the fermentation gas from rushing out and being inhaled by the user, which is harmful to the user's health. Moreover, the fermentation gas has a strong pungent smell and is likely 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 downward further. At this time, all the fermentation gas has been discharged into the collection bag 34. Then the user moves the connecting frame 3 and the barrel cover 4 upward, and through the first limit block 2001 and the second limit block 2002, connects the connecting frame 3 to the mounting ring 2, 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 has not been opened for too long, the pressure of the fermenting gas pushes the connecting frame 3 and the barrel cover 4 upward until the outer connecting ring 3001 contacts the lower side of the first limiting block 2001. At this time, the connecting frame 3 and the barrel cover 4 cannot move upward any further, and the fermenting gas in the cavity under the barrel cover 4 will continue to accumulate, increasing the cavity pressure. Since the fermenting barrel 1 is usually made of plastic, excessive pressure is likely to cause the fermenting barrel 1 to deform. Therefore, when the pressure of the fermenting gas accumulating in the cavity under the barrel cover 4 is too high, the closing block 5 will be pushed upward, and the closing block 5 will simultaneously compress the elastic member 4003, causing the exhaust port 4001 to open for pressure relief. At this time, it is communicated with the first group of one-way valves 33 and the connecting hole 3201, and the fermenting 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 under the barrel cover 4 is the same as the external pressure, there is no upward thrust on the closing block 5, and the elastic member 4003 expands, pushing the closing block 5 downward to reset and re-close the exhaust port 4001. Thus, the pressure in the cavity under the barrel cover 4 is automatically released, preventing the fermenting barrel 1 from deforming due to excessive cavity pressure and preventing external air from entering the cavity, which affects the anaerobic fermentation environment in the cavity.

[0057] Embodiment 3

[0058] Based on Embodiment 2, as Figure 3 、 Figure 5 and Figure 9 shown, it further includes a micro air pump 42 and an air supply pipe 43; the seal 41 is a rubber airbag; at least one micro air pump 42 is bolted to the barrel cover 4; the outlet of each micro air pump 42 is communicated with an air supply pipe 43; the air supply pipe 43 is communicated with the seal 41, and the size of the seal 41 is changed by supplying air and sucking air through the micro air pump 42.

[0059] When the height of the remaining feed is close to the bottom of the fermenting barrel 1, the user pushes the connecting frame 3 and the barrel cover 4 downward to the corresponding height. When the user needs to open the barrel cover 4 again to take the feed, the positions of the connecting frame 3 and the barrel cover 4 are deep and far from the mouth of the fermenting barrel 1. The user needs to bend down and stretch the body into the fermenting barrel 1 to lift the connecting frame 3 and the barrel cover 4. Since the seal 41 is in close contact with the inner wall of the fermenting barrel 1 to ensure airtightness and the friction is large, when the user lifts the connecting frame 3 and the barrel cover 4 from the bottom of the fermenting barrel 1, the resistance is large, and the posture of the user stretching the body into the fermenting barrel 1 is inconvenient for applying force, making it difficult to lift the connecting frame 3 and the barrel cover 4.

[0060] When the connecting frame 3 and the bucket lid 4 are close to the bottom of the fermentation barrel 1 and the user needs to lift the connecting frame 3 and the bucket lid 4, the micro air pump 42 is controlled to work. The micro air pump 42 pumps out the air inside the seal 41 through the air supply pipe 43, causing the seal 41 to contract and not contact the inner wall of the fermentation barrel 1. Then, when the user lifts the connecting frame 3 and the bucket lid 4, the seal 41 does not generate resistance, facilitating the user to bend down and reach into the fermentation barrel 1 to lift the connecting frame 3 and the bucket lid 4. When the user needs to re-seal the fermentation barrel 1, the micro air pump 42 is controlled to supply air to the seal 41, causing the seal 41 to expand to the same diameter as the inner diameter of the fermentation barrel 1, normally achieving the sealing function.

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

[0062] The above are only examples of the present invention and are not intended to limit the present invention. All equivalent replacements made within the principles of the present invention shall be included within the protection scope of the present invention. The content not elaborated in detail in the present invention belongs to the well-known prior art of those skilled in the art.
