Description

Technical Field

[0001] The invention relates to the technical field of packaging devices, and in particular to a feed quantitative packaging device for feed production. Background Art

[0002] As an important type of feed, silage plays a vital role in animal husbandry. It is made from water-rich plant feed that is sealed and fermented. It is mainly used to feed ruminants. Compared with fresh feed and dry feed, silage has significant advantages. First of all, the storage resistance of silage is one of its major characteristics. Due to the fermentation process, the microbial activity in silage is inhibited, thereby extending its shelf life. Secondly, the nutritional content of silage is richer than that of dry feed.

[0003] In the process of packaging silage, currently most of the packaging is completed by wrapping the silage with layers of stretch film on the packaging device. However, although the stretch film has certain flexibility and stretchability, it may break due to friction, pressure or sharp parts of the feed when facing silage containing sharp edges or hard particles. This penetration phenomenon will not only affect the integrity of the package, but also may cause the silage to contact with the external environment during the fermentation process, thereby affecting the fermentation effect and the quality of the feed. To address this problem, the staff have to use special fermentation bags for secondary packaging. However, when packaging the silage with fermentation bags, since the fermentation bags themselves are not elastic, in order to avoid rupture due to the fermentation and expansion of the feed inside, the silage cannot usually be compacted well during the packaging process. However, insufficient compaction will cause the fermented feed to be too fluffy, thereby affecting the fermentation effect, that is, reducing the packaging quality of the silage, and the practicality is not good.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The present invention can not only conveniently complete the packaging of silage by filling the fermentation bag and wrapping the packaging tape through the cooperation of the transmission mechanism, the fixed straightening mechanism, the pleat clamping mechanism, the wrapping mechanism and the hammer adjustment mechanism, but also enable the packaged fermentation bag to flexibly adapt to the natural expansion demand of the silage during the fermentation process, that is, it can ensure that the silage is fully compacted to promote the fermentation effect, and at the same time, it can avoid the problem of fermentation bag rupture caused by the expansion of the silage fermentation, thereby effectively ensuring the fermentation effect of the silage, and then effectively improving the packaging quality of the silage.

[0021] 2. The present invention can fix the fermentation bag by setting a fixed straightening mechanism and utilizing the setting of a ring and a fixing assembly, and can open and longitudinally straighten the fermentation bag by moving the compaction roller downward and the ring upward, thereby effectively increasing the effective utilization rate of the internal space of the fermentation bag, thereby optimizing the use effect of the fermentation bag and being more conducive to the subsequent silage filling operation.

[0022] 3. The present invention fixes the arrangement of the compacting roller in the straightening mechanism, so that when the fermentation bag is filled with silage, the compacting roller can rotate and move upward to compact the entire bag of silage, and by setting multiple groups of compacting belt positions on different compacting rollers, it can ensure the comprehensiveness of the compaction of the upper end surface of the silage while forming a height difference on the upper end surface. This height difference helps the feed to form a tighter stacking structure during the compaction process, thereby increasing the contact area and bonding force between layers and reducing gaps in the feed, thereby further improving the compaction density of the feed, that is, it is more conducive to ensuring the subsequent fermentation effect. In addition, by fixing the arrangement of the support roller in the straightening mechanism, it can be ensured that the fermentation bag is always in an open state, preventing the problem of the subsequent compacting roller being unable to be removed after the fermentation bag is wrapped too tightly with the packing tape.

[0023] 4. The present invention can reserve longitudinal folds in the fermentation bag through the cooperation between the wrinkle clamping mechanism and the wrapping mechanism. In the case where the longitudinal folds are reserved, the packing tape in the wrapping mechanism can be used to wrap the fermentation bag. The fermentation bag is adsorbed and clamped by the upper and lower clamps in the wrinkle clamping mechanism, so that wrinkles can be clamped out of the adsorbed fermentation bag part. At the same time, after the wrinkles are clamped out, the wrinkles on the fermentation bag can be extended to a length matching the height of the fermentation bag by moving the upper clamp upward. The reserved wrinkles can ensure that when the fermentation bag expands due to the fermentation of the feed inside it, the feed can still be well wrapped, thereby preventing the fermentation bag from rupturing due to excessive internal pressure, and further preventing the fermentation failure of the feed inside due to the rupture of the fermentation bag, effectively ensuring the fermentation effect.

[0024] 5. The present invention, through the setting of the wrapping mechanism, utilizes the setting that the rotation speed of the upper electrically-controlled rotating shaft is slightly higher than that of the lower electrically-controlled rotating shaft, so that the packing belts on the two sets of electrically-controlled rotating shafts can be respectively wrapped around the fermentation bag with different tightness, that is, the wrapping tightness of the packing belt (inner belt) wrapped first can be lower than that of the subsequent packing belt (outer belt). When the silage is fermented and the fermentation bag expands, since the wrapping effect of the inner belt is looser than that of the outer belt, the outer belt will first break due to the limit of elastic force. At this time, the inner belt begins to assume the role of the previous outer belt, that is, continue to maintain the compression and wrapping of the silage inside the fermentation bag to prevent the feed from becoming loose in structure due to the loss of external pressure, thereby effectively ensuring that the fermentation effect of the silage is not affected, that is, further ensuring the fermentation effect.

[0025] 6. The present invention, through the setting of the hammer adjustment mechanism, utilizes the upward movement of the first air hammer and the second air hammer to hammer the fermentation bag during wrapping. The hammering of the first air hammer can further reduce the gap between the feed particles in the fermentation bag, thereby increasing the compactness and uniformity of the feed (i.e., further improving the compaction of the silage), and further improving the fermentation effect. The hammering of the second air hammer cooperates with the intermittent adsorption of the strapping tape by the air intake port on the contact plate thereon, so that the adsorbed strapping tape can be pulled out and re-attached. During this re-attaching process, due to the elasticity of the strapping tape and the irregularity of the surface of the fermentation bag, its tensile stress will be quickly distributed and adjusted, which not only makes the strapping tape more evenly wrapped around the fermentation bag, but also prevents the strapping tape from prematurely breaking due to stress concentration during the fermentation process, thereby ensuring the silage fermentation effect and improving the wrapping quality of the strapping tape, thereby improving the packaging quality of the silage.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The transmission mechanism includes a protective shell 12 and a synchronization rod 22. The protective shell 12 is installed on the mounting plate and the side wall of the turntable 2, and three groups of through grooves for the upper synchronous disk 21, the lower synchronous disk 23 and the electronic scale 24 to pass through are opened at the opening of the protective shell 12. Rotating blocks are installed at both ends of the synchronization rod 22, and the synchronization rod 22 is rotatably connected to the inside of the protective shell 12 through two groups of rotating blocks. The side walls of the two groups of rotating blocks are in friction contact with the side walls of the upper synchronous disk 21 and the lower synchronous disk 23 respectively.

[0040] Reference Figures 2 to 4 as well as Figure 8 A fixed straightening mechanism is provided on the inner wall of the upper synchronous disk 21, which is used to fix the fermentation bag and to open and longitudinally straighten the fixed fermentation bag. The fixed straightening mechanism includes a collar 32, a third push rod 5 and a fixing assembly. The collar 32 is installed on the fixing assembly, and the collar 32 is used to sleeve the fermentation bag. The fixing assembly is arranged at the bottom end of the upper synchronous disk 21, and is used to clamp and fix the fermentation bag sleeved on the collar 32. The fixing assembly includes four groups of first push rods 3, and the four groups of first push rods 3 are evenly installed at the bottom end of the upper synchronous disk 21. The output ends of the first push rods 3 are all fixedly connected to the transverse push rods 31, and the output ends of the four groups of transverse push rods 31 are all fixedly connected to the pressing plates 311, and the bottom ends of the four groups of transverse push rods 31 are all installed with fixing blocks 321, and the four groups of transverse push rods 31 are fixedly connected to the side walls of the collar 32 through the fixing blocks 321. A plurality of connecting rods 50 are installed on the third push rod 5, and the third push rod 5 is installed on the inner wall of the upper synchronization disk 21 through the plurality of connecting rods 50, the third push rod 5 is located at the center of the collar 32, and the output end of the third push rod 5 is fixedly connected with a mounting rod, and four groups of laterally arranged compacting rollers 51 are evenly installed on the outer wall of the mounting rod near the bottom end, and a plurality of compacting belts 511 are installed on the outer walls of the four groups of compacting rollers 51, and the positions of the plurality of compacting belts 511 on the two symmetrical groups of compacting rollers 51 are the same, and the positions of the plurality of compacting belts 511 on the two adjacent groups of compacting rollers 51 are staggered with each other, and four groups of support rods are evenly installed on the outer wall of the mounting rod near the top end, and support rollers 52 are installed near the edge at the bottom ends of the four groups of support rods, and the bottom ends of the four groups of support rollers 52 are respectively fixedly connected to the outer walls of the four groups of compacting rollers 51.

[0041] When it is necessary to carry out packaging operation, first, the pressing plate 311 is controlled to move in the direction away from the ring 32 by the horizontal push rod 31. At this time, the staff can put the fermentation bag on the ring 32. At this time, the horizontal push rod 31 controls the pressing plate 311 to move towards the fermentation bag until it fits with the outer wall of the ring 32 (that is, the fermentation bag part at the outer wall of the ring 32 is tightly clamped), thereby completing the fixing operation of the fermentation bag. Thereafter, the third push rod 5 is turned on to make the compacting roller 51 move downward, so that the fermentation bag can be stretched out. When the compacting roller 51 fits with the electronic scale 24, the start of the third push rod 5 is stopped, and the first push rod 3 is turned on at the same time, so that the horizontal push rod 31 starts to move upward. Since the horizontal push rod 31 is connected to the ring 32 through the fixing block 321, the upward movement of the horizontal push rod 31 will drive the ring 32 to move upward, so that the fermentation bag can be pulled longitudinally until the fermentation bag is in a straightened state. At this time, the first push rod 3 will record its own tension change data.

[0042] Reference Figures 3 to 7 The bottom end of the upper synchronization disk 21 is provided with a pleat clamping mechanism for forming two groups of longitudinal pleats on the fermentation bag. The pleat clamping mechanism includes two groups of second push rods 4 and two groups of support columns. The bottom ends of the two groups of second push rods 4 are both equipped with upper clamps 41. The inward ends of the two groups of upper clamps 41 are both provided with upper air ports 411. The two groups of outer side walls of the two groups of upper clamps 41 are both slidably connected with upper sliders 412. The top ends of the two groups of support columns are both equipped with lower clamps 42. A lower air port 421 is provided at one end facing inwards of the lower clamps 42, and lower sliders 422 are slidably connected to the two sets of outer walls on the two sets of lower clamps 42. The upper air port 411 and the lower air port 421 are connected to an external air suction device at one end facing outwards. The two sets of outer walls on the two sets of upper clamps 41 are inclined toward the opening of the upper air port 411, and the two sets of outer walls on the two sets of lower clamps 42 are inclined toward the opening of the lower air port 421.

[0043] After the fermentation bag is stretched and straightened longitudinally, the lower air port 421 on the lower clamp 42 starts to evacuate air through the external air suction device, so that the surface of the fermentation bag is adsorbed, and at the same time, the two groups of lower sliders 422 slide toward the fermentation bag. Due to the inclined setting of the outer wall of the lower clamp 42, when the two groups of lower sliders 422 slide toward the fermentation bag, they also move towards each other, so that the adsorbed fermentation bag part can be clamped (that is, wrinkles are clamped). The operating principle of the upper clamp 41 is the same as that of the lower clamp 42. After the fermentation bag is wrinkled, the upper clamp 41 starts to move upward by starting the second push rod 4, thereby driving the upper slider 412 to move upward. While the upper slider 412 moves upward, the staff can perform the filling and wrapping operation on the fermentation bag ( Specific steps are described later). When the upper slider 412 moves upward, the folds on the fermentation bag will be extended until the upper slider 412 moves to the opening of the fermentation bag. Since the filling and wrapping operation will be performed simultaneously during the movement of the upper slider 412, the folds will be folded and wrapped into the entire package. During the fermentation of the silage, its volume will expand, thereby causing the fermentation bag to expand as well. At this time, the folds on the fermentation bag can serve as reserved space. The reserved folds can ensure that when the fermentation bag expands due to the fermentation of the feed inside it, it can still wrap the feed well, thereby preventing the fermentation bag from rupturing due to excessive internal pressure, thereby preventing the internal feed from failing to ferment due to the rupture of the fermentation bag, and effectively ensuring the fermentation effect.

[0044] At the same time, due to the inclined setting of the outer walls of the lower clamp 42 and the upper clamp 41, when the fermentation bag is slid and clamped by the two groups of lower sliders 422 and the two groups of upper sliders 412, a larger gap will be generated between the two groups of lower sliders 422 and between the two groups of upper sliders 412 at a position farther away from the fermentation bag, so that the rear half of the wrinkles clamped on the fermentation bag can be located in the above-mentioned gap, that is, the complete clamping of the wrinkles of the fermentation bag can be avoided, thereby effectively reducing the risk of damage to the fermentation bag by the two groups of upper sliders 412 during the upward movement process.

[0045] Reference Figure 1 , Figure 2 and Fig.11 A wrapping mechanism is provided at the top of the base 1 for wrapping the fermentation bag, and the wrapping mechanism includes an electric slide rail 7, which is fixedly installed at the top of the base 1 in a vertical state, and the electric slide rail 7 is slidably connected to the inner side with two sets of lifting sliders 71, and the tops of the two sets of lifting sliders 71 are both installed with electric control shafts 72, and the outer walls of the two sets of electric control shafts 72 are both wound with packing tapes 73, and the rotation rate of the upper electric control shaft 72 is slightly higher than the rotation rate of the lower electric control shaft 72.

[0046] When the upper clamp 41 moves up and produces extended wrinkles, the crushed silage is gradually poured into the fermentation bag from the hollow space between the turntable 2 and the upper synchronous disk 21 through the feed port 8. Then the staff sticks the packing tape 73 on the two sets of electric-controlled rotating shafts 72 to the surface of the fermentation bag, and makes the upper synchronous disk 21 start to rotate through the rotating part at the bottom of the turntable 2. Since the side walls of the two sets of rotating blocks on the synchronous rod 22 are in friction contact with the side walls of the upper synchronous disk 21 and the lower synchronous disk 23 respectively, the synchronous rod 22 can play a transmission role when the upper synchronous disk 21 rotates, that is, when the upper synchronous disk 21 rotates, the lower synchronous disk 23, the electronic scale 24 and the lower clamp 42 will rotate together During the rotation, the packing belt 73 will wrap around the surface of the fermentation bag to form a new layer of wrapping film, and in the process of wrapping the packing belt 73, the wrinkles created by the upper clamp 41 and the lower clamp 42 will be folded and wrapped to ensure that the subsequent filler can still compact the feed and exhaust air in the presence of wrinkles, so as to improve the subsequent fermentation effect (the fermentation effect is highly correlated with the compaction degree of silage). Since the wrapping of the packing belt 73 is mainly achieved by the rotation of the fermentation bag on the ring 32 (i.e., the rotation of the upper synchronous disk 21), the wrapping speed of the packing belt 73 is uniform.

[0047] During the winding process of the packing belt 73, since the third push rod 5 and the upper synchronous disk 21 are fixedly connected by the connecting rod 50, the rotation of the upper synchronous disk 21 will drive the compacting roller 51 and the supporting roller 52 on the third push rod 5 to rotate, and the compacting roller 51 will compact the silage fed into the feed inlet 8. Since the multiple groups of compacting belts 511 on the two symmetrical groups of compacting rollers 51 are in the same position, and the multiple groups of compacting belts 511 on the two adjacent groups of compacting rollers 51 are in a staggered state, it can ensure that every part of the upper end surface of the silage is pressed, and at the same time, a height difference can be formed on the upper end surface. This height difference helps the feed to form a tighter compaction during the compaction process. The stacked structure, because the newly added feed will fill the height difference formed before, thereby increasing the contact area and bonding force between the layers, and at the same time the above-mentioned stacked structure helps to reduce the gaps in the feed, thereby further improving the compaction density of the feed, that is, it is more conducive to ensuring the subsequent fermentation effect. As the packing belt 73 gradually wraps the fermentation bag, if the fermentation bag itself does not have sufficient support, it may shrink or deform due to the internal pressure. At this time, the support roller 52 can ensure that the fermentation bag is always in an open state, preventing the packing belt 73 from wrapping the fermentation bag too tightly, and the subsequent compaction roller 51 cannot be taken out due to the shrinkage or deformation of the fermentation bag.

[0048] When the compacting roller 51 compacts the silage, the third push rod 5 will record its own pressure change data. When the pressure of the third push rod 5 reaches a certain value, that is, the silage is compacted to a sufficient degree for fermentation, the third push rod 5 will control the compacting roller 51 to move up a certain distance and re-compact a new layer of silage. The compacting and moving up rate of the compacting roller 51 is greater than the winding rate of the packing belt 73 (that is, greater than the rotation rate of the upper synchronous disk 21). This ensures that before the packing belt 73 completes the winding of the current layer and prepares to start the winding of the next layer, the compacting roller 51 is ready for compacting the new layer of silage. This process will be repeated until the entire bag of silage is compacted, thereby achieving reasonable compaction of the silage, avoiding the problem of poor fermentation effect or feed damage caused by uneven compaction or excessive compaction, and further ensuring the fermentation effect.

[0049] The electric slide rail 7 can control the two sets of lifting sliders 71 to move upward, thereby controlling the two sets of strapping belts 73 to move upward, so that the strapping belt 73 can completely wrap the side end surface of the fermentation bag, and the electric control shaft 72 can control the rotation speed of the strapping belt 73 (that is, control the speed of the strapping belt 73 releasing the belt when wrapping the fermentation bag). Since the strapping belt 73 is wound at a uniform speed, and the rotation speed of the electric control shaft 72 located at the top is slightly higher than the rotation speed of the electric control shaft 72 located at the bottom, in the same time, the length of the strapping belt 73 located at the top (hereinafter referred to as the inner belt) released will be longer than the length of the strapping belt 73 located at the bottom (hereinafter referred to as the outer belt), so it can Ensure that the winding tightness of the inner belt that is wound first is not as high as the winding tightness of the subsequent outer belt. When the silage is fermented and the fermentation bag expands, the outer belt will first burst due to the limit of elastic force because the winding effect of the inner belt is looser than that of the outer belt. At this time, the inner belt has not yet reached the limit of elastic force, so it begins to assume the role of the previous outer belt, that is, continue to maintain the compression and wrapping of the silage inside the fermentation bag to prevent the feed from loosening its structure due to the loss of external pressure, and finally achieve the effect of the outer belt bursting step by step to the inner belt. This step-by-step bursting effect helps to maintain continuous compression of the silage inside the fermentation bag when the fermentation bag expands, thereby effectively ensuring that the fermentation effect of the silage is not affected.

[0050] Reference Figure 1 to Figure 2 as well as Figures 9 and 10Two groups of hammer adjustment mechanisms are symmetrically arranged at the top of the base 1, which are used to hammer the fermentation bag during wrapping and make the packing belt 73 more evenly wrap the fermentation bag. The hammer adjustment mechanism includes two groups of fourth push rods 6, which are symmetrically installed on the top of the base 1, and four groups of connecting pieces 61 are commonly installed on the output ends of the two groups of fourth push rods 6. The four groups of connecting pieces 61 are all elastic, and the first air hammer 62 is commonly installed on the two groups of connecting pieces 61 located at the top, and the second air hammer 63 is commonly installed on the two groups of connecting pieces 61 located at the bottom. A contact plate 64 is installed at the output end of the second air hammer 63, and four groups of corners of the contact plate 64 away from the second air hammer 63 are provided with air suction ports 642, and four groups of air exhaust ports 641 connected to the inside of the four groups of air suction ports 642 are respectively installed on the contact plate 64, and the four groups of air exhaust ports 641 are connected to the intermittent air exhaust device outside.

[0051] The fourth push rod 6 can control the lifting of the connecting piece 61, thereby controlling the lifting of the first air hammer 62 and the second air hammer 63, so that the first air hammer 62 and the second air hammer 63 can rise with the rising rate of the lifting slider 71. This design can ensure that the first air hammer 62 and the second air hammer 63 hammer the fermentation bag at an appropriate time. The first air hammer 62 and the second air hammer 63 mainly use an external compressor to provide power for them, so that they move quickly toward the fermentation bag and generate a striking force. Since the connecting piece 61 is elastic, The fourth push rod 6 can be protected from being damaged by the recoil force during the hammering of the fermentation bag by the first air hammer 62 and the second air hammer 63. After the packing belt 73 on the lifting slider 71 wraps the fermentation bag, the first air hammer 62 and the second air hammer 63 immediately hammer the fermentation bag. The hammering of the first air hammer 62 can further reduce the gap between the feed particles in the fermentation bag, thereby increasing the compactness and uniformity of the feed (i.e., further improving the compaction of the silage), thereby further improving the fermentation effect. The hammering of the second air hammer 63 is to make the contact plate The contact plate 64 is attached to the surface of the fermentation bag wrapped with the strapping tape 73. Since the four groups of air suction ports 641 are connected to the intermittent air suction device outside, when the air suction port 642 is evacuated, the contact plate 64 will suck the attached strapping tape 73. Then, the contact plate 64 will temporarily move away from the surface of the fermentation bag under the action of the second air hammer 63. At this time, the sucked strapping tape 73 will be pulled out. Then, since it is intermittent air suction, after the air suction is finished, the suction effect of the air suction port 642 on the strapping tape 73 disappears, and the strapping tape 73 will quickly stick back to the surface of the fermentation bag under the action of elastic force. During the process, due to the elasticity of the strapping tape 73 and the irregularity of the surface of the fermentation bag, the tensile stress of the strapping tape 73 will be quickly distributed and adjusted. This mechanism cleverly solves the problem of uneven tensile stress of the strapping tape 73 caused by external factors such as the winding rate. This not only makes the strapping tape 73 more evenly applied to the fermentation bag, but also prevents the strapping tape 73 from cracking prematurely due to stress concentration during the fermentation process, thereby ensuring the silage fermentation effect and improving the wrapping quality of the strapping tape 73, thereby improving the packaging quality of the silage.

[0052] The electronic scale 24 has the functions of weighing, receiving signals and real-time calculation. When weighing the fermentation bag, it will add the data recorded by the first push rod 3 in real time and subtract the data recorded by the third push rod 5 at the same time to ensure the weighing accuracy of the silage weight inside the fermentation bag. When the electronic scale 24 weighs the fermentation bag to the expected weight, it stops the silage feeding operation and waits for the compaction operation of the compaction roller 51 and the wrapping operation of the packing belt 73 to be completed. Finally, when the fermentation bag is completely packed and reaches the required tightness, the staff will take out the fermentation bag containing silage and perform subsequent vacuum sealing operations.

[0053] When the bag is packed with the bag 31, the staff can put the bag on the bag 32, and then the pressing plate 311 is moved to the direction of the bag 31, so that the bag 31 is fixed to the bag 32.

[0054] After the fermentation bag is stretched and straightened longitudinally, the lower air port 421 on the lower clamp 42 starts to evacuate air through the external air suction device, so that the surface of the fermentation bag is adsorbed, and at the same time, the two groups of lower sliders 422 slide toward the fermentation bag. Due to the inclined setting of the outer wall of the lower clamp 42, when the two groups of lower sliders 422 slide toward the fermentation bag, they also move towards each other, so that the adsorbed fermentation bag part can be clamped (that is, wrinkles are clamped). The operating principle of the upper clamp 41 is the same as that of the lower clamp 42. After the fermentation bag is wrinkled, the upper clamp 41 starts to move upward by starting the second push rod 4, thereby driving the upper slider 412 to move upward. While the upper slider 412 moves upward, the staff can perform the filling and wrapping operation on the fermentation bag ( Specific steps are described later). When the upper slider 412 moves upward, the folds on the fermentation bag will be extended until the upper slider 412 moves to the opening of the fermentation bag. Since the filling and wrapping operation will be performed simultaneously during the movement of the upper slider 412, the folds will be folded and wrapped into the entire package. During the fermentation of the silage, its volume will expand, thereby causing the fermentation bag to expand as well. At this time, the folds on the fermentation bag can serve as reserved space. The reserved folds can ensure that when the fermentation bag expands due to the fermentation of the feed inside it, it can still wrap the feed well, thereby preventing the fermentation bag from rupturing due to excessive internal pressure, thereby preventing the internal feed from failing to ferment due to the rupture of the fermentation bag, and effectively ensuring the fermentation effect.

[0055] At the same time, due to the inclined setting of the outer walls of the lower clamp 42 and the upper clamp 41, when the fermentation bag is slid and clamped by the two groups of lower sliders 422 and the two groups of upper sliders 412, a larger gap will be generated between the two groups of lower sliders 422 and between the two groups of upper sliders 412 at a position farther away from the fermentation bag, so that the rear half of the wrinkles clamped on the fermentation bag can be located in the above-mentioned gap, that is, the complete clamping of the wrinkles of the fermentation bag can be avoided, thereby effectively reducing the risk of damage to the fermentation bag by the two groups of upper sliders 412 during the upward movement process.

[0056] When the upper clamp 41 moves up and produces extended wrinkles, the crushed silage is gradually poured into the fermentation bag from the hollow space between the turntable 2 and the upper synchronous disk 21 through the feed port 8. Then the staff sticks the packing tape 73 on the two sets of electric-controlled rotating shafts 72 to the surface of the fermentation bag, and makes the upper synchronous disk 21 start to rotate through the rotating part at the bottom of the turntable 2. Since the side walls of the two sets of rotating blocks on the synchronous rod 22 are in friction contact with the side walls of the upper synchronous disk 21 and the lower synchronous disk 23 respectively, the synchronous rod 22 can play a transmission role when the upper synchronous disk 21 rotates, that is, when the upper synchronous disk 21 rotates, the lower synchronous disk 23, the electronic scale 24 and the lower clamp 42 will rotate together During the rotation, the packing belt 73 will wrap around the surface of the fermentation bag to form a new layer of wrapping film, and in the process of wrapping the packing belt 73, the wrinkles created by the upper clamp 41 and the lower clamp 42 will be folded and wrapped to ensure that the subsequent filler can still compact the feed and exhaust air in the presence of wrinkles, so as to improve the subsequent fermentation effect (the fermentation effect is highly correlated with the compaction degree of silage). Since the wrapping of the packing belt 73 is mainly achieved by the rotation of the fermentation bag on the ring 32 (i.e., the rotation of the upper synchronous disk 21), the wrapping speed of the packing belt 73 is uniform.

[0057] During the winding process of the packing belt 73, since the third push rod 5 and the upper synchronous disk 21 are fixedly connected by the connecting rod 50, the rotation of the upper synchronous disk 21 will drive the compacting roller 51 and the supporting roller 52 on the third push rod 5 to rotate, and the compacting roller 51 will compact the silage fed into the feed inlet 8. Since the multiple groups of compacting belts 511 on the two symmetrical groups of compacting rollers 51 are in the same position, and the multiple groups of compacting belts 511 on the two adjacent groups of compacting rollers 51 are in a staggered state, it can ensure that every part of the upper end surface of the silage is pressed, and at the same time, a height difference can be formed on the upper end surface. This height difference helps the feed to form a tighter compaction during the compaction process. The stacked structure, because the newly added feed will fill the height difference formed before, thereby increasing the contact area and bonding force between the layers, and at the same time the above-mentioned stacked structure helps to reduce the gaps in the feed, thereby further improving the compaction density of the feed, that is, it is more conducive to ensuring the subsequent fermentation effect. As the packing belt 73 gradually wraps the fermentation bag, if the fermentation bag itself does not have sufficient support, it may shrink or deform due to the internal pressure. At this time, the support roller 52 can ensure that the fermentation bag is always in an open state, preventing the packing belt 73 from wrapping the fermentation bag too tightly, and the subsequent compaction roller 51 cannot be taken out due to the shrinkage or deformation of the fermentation bag.

[0058] When the compacting roller 51 compacts the silage, the third push rod 5 will record its own pressure change data. When the pressure of the third push rod 5 reaches a certain value, that is, the silage is compacted to a sufficient degree for fermentation, the third push rod 5 will control the compacting roller 51 to move up a certain distance and re-compact a new layer of silage. The compacting and moving up rate of the compacting roller 51 is greater than the winding rate of the packing belt 73 (that is, greater than the rotation rate of the upper synchronous disk 21). This ensures that before the packing belt 73 completes the winding of the current layer and prepares to start the winding of the next layer, the compacting roller 51 is ready for compacting the new layer of silage. This process will be repeated until the entire bag of silage is compacted, thereby achieving reasonable compaction of the silage, avoiding the problem of poor fermentation effect or feed damage caused by uneven compaction or excessive compaction, and further ensuring the fermentation effect.

[0059] The electric slide rail 7 can control the two sets of lifting sliders 71 to move upward, thereby controlling the two sets of strapping belts 73 to move upward, so that the strapping belt 73 can completely wrap the side end surface of the fermentation bag, and the electric control shaft 72 can control the rotation speed of the strapping belt 73 (that is, control the speed of the strapping belt 73 releasing the belt when wrapping the fermentation bag). Since the strapping belt 73 is wound at a uniform speed, and the rotation speed of the electric control shaft 72 located at the top is slightly higher than the rotation speed of the electric control shaft 72 located at the bottom, in the same time, the length of the strapping belt 73 located at the top (hereinafter referred to as the inner belt) released will be longer than the length of the strapping belt 73 located at the bottom (hereinafter referred to as the outer belt), so it can Ensure that the winding tightness of the inner belt that is wound first is not as high as the winding tightness of the subsequent outer belt. When the silage is fermented and the fermentation bag expands, the outer belt will first burst due to the limit of elastic force because the winding effect of the inner belt is looser than that of the outer belt. At this time, the inner belt has not yet reached the limit of elastic force, so it begins to assume the role of the previous outer belt, that is, continue to maintain the compression and wrapping of the silage inside the fermentation bag to prevent the feed from loosening its structure due to the loss of external pressure, and finally achieve the effect of the outer belt bursting step by step to the inner belt. This step-by-step bursting effect helps to maintain continuous compression of the silage inside the fermentation bag when the fermentation bag expands, thereby effectively ensuring that the fermentation effect of the silage is not affected.

[0060] The fourth push rod 6 can control the lifting of the connecting piece 61, thereby controlling the lifting of the first air hammer 62 and the second air hammer 63, so that the first air hammer 62 and the second air hammer 63 can rise with the rising rate of the lifting slider 71. This design can ensure that the first air hammer 62 and the second air hammer 63 hammer the fermentation bag at an appropriate time. The first air hammer 62 and the second air hammer 63 mainly use an external compressor to provide power for them, so that they move quickly toward the fermentation bag and generate a striking force. Since the connecting piece 61 is elastic, The fourth push rod 6 can be protected from being damaged by the recoil force during the hammering of the fermentation bag by the first air hammer 62 and the second air hammer 63. After the packing belt 73 on the lifting slider 71 wraps the fermentation bag, the first air hammer 62 and the second air hammer 63 immediately hammer the fermentation bag. The hammering of the first air hammer 62 can further reduce the gap between the feed particles in the fermentation bag, thereby increasing the compactness and uniformity of the feed (i.e., further improving the compaction of the silage), thereby further improving the fermentation effect. The hammering of the second air hammer 63 is to make the contact plate The contact plate 64 is attached to the surface of the fermentation bag wrapped with the strapping tape 73. Since the four groups of air suction ports 641 are connected to the intermittent air suction device outside, when the air suction port 642 is evacuated, the contact plate 64 will suck the attached strapping tape 73. Then, the contact plate 64 will temporarily move away from the surface of the fermentation bag under the action of the second air hammer 63. At this time, the sucked strapping tape 73 will be pulled out. Then, since it is intermittent air suction, after the air suction is finished, the suction effect of the air suction port 642 on the strapping tape 73 disappears, and the strapping tape 73 will quickly stick back to the surface of the fermentation bag under the action of elastic force. During the process, due to the elasticity of the strapping tape 73 and the irregularity of the surface of the fermentation bag, the tensile stress of the strapping tape 73 will be quickly distributed and adjusted. This mechanism cleverly solves the problem of uneven tensile stress of the strapping tape 73 caused by external factors such as the winding rate. This not only makes the strapping tape 73 more evenly applied to the fermentation bag, but also prevents the strapping tape 73 from cracking prematurely due to stress concentration during the fermentation process, thereby ensuring the silage fermentation effect and improving the wrapping quality of the strapping tape 73, thereby improving the packaging quality of the silage.
