Description

Technical Field

[0001] The invention relates to the technical field of silage devices, in particular to an automatic vacuum forage silage tank. Background Art

[0002] The silage of forage refers to the process of sealing the forage and isolating it from the outside air, causing internal hypoxia, leading to anaerobic fermentation, and producing organic acids. The fresh forage is subjected to lactic acid fermentation in an anaerobic environment to produce a juicy, storable feed that can be used by livestock for a long time. The forage is usually processed by silage tanks.

[0003] However, during the use of the silage tank, after a part of the forage is added, in order to remove the air in the silage itself, the operator will compact the silage by stepping on it to increase the storage density. The operator's stepping on the silage will result in slow compaction efficiency. At the same time, after the forage is added, the air inside the silage tank will be extracted by a vacuum pump. After the silage tank is sealed, the stored forage is isolated from the outside air, causing internal hypoxia and anaerobic fermentation, thereby producing organic acids, which can preserve the forage for a long time. When the vacuum pump extracts the internal air, if some of the forage is sucked up by the vacuum pump, the forage will enter the vacuum pump and damage the vacuum pump. At the same time, after the internal air is extracted, the connecting pipe from the vacuum pump suction port and the threaded sleeve on the barrel cover are usually disassembled, and then the sealing cover and the threaded sleeve are threadedly connected for sealing. When the connecting pipe is disassembled and the sealing cover is installed, oxygen will also enter the silage tank, thereby affecting the silage effect of the forage. Summary of the invention

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.14 and Fig.15As shown, an automatic vacuum forage silage tank described in the present invention includes a silage tank body 1, a downward pressure structure 2 installed on the silage tank body 1, a connecting cover 8 threadedly connected to the top of the silage tank body 1, a fixing frame 9 installed on the connecting cover 8, an exhaust structure 5 arranged between the downward pressure structure 2 and the fixing frame 9, a sealing structure 4 installed in the fixing frame 9, and a filtering structure 7 installed in the fixing frame 9; the downward pressure structure 2 includes two mounting sleeves 201 fixedly connected to the side wall of the silage tank body 1 and a mounting block 202 detachably connected to the mounting sleeve 201, a connecting ring 203 is fixedly connected between the two mounting blocks 202, a mounting frame 204 is fixedly connected to the left side of the connecting ring 203, and a base 205 is fixedly connected to the bottom of the mounting frame 204. A hydraulic rod 206 is installed on the mounting frame 204, and the telescopic end of the hydraulic rod 206 is fixedly connected to a mounting frame 207, and a mounting shaft 208 is rotatably connected in the mounting frame 207, and a mounting rod 209 is fixedly connected to the mounting shaft 208, and a connecting shaft 210 is fixedly connected below the mounting rod 209, and a pressing plate 211 is fixedly connected below the connecting shaft 210; the exhaust structure 5 includes a connecting frame 501 fixedly connected to the top of the fixed frame 9 and a threaded sleeve 502 fixedly connected to the connecting frame 501, a connecting sleeve 503 is threadedly connected to the threaded sleeve 502, and a connecting pipe 504 is rotatably connected to the connecting sleeve 503, a vacuum pump 506 is installed on the base 205, and the other end of the connecting pipe 504 is installed at the suction port of the vacuum pump 506.

[0040] Specifically, Figure 1 , Figure 5 , Figure 7 and Fig.11 As shown, a motor 212 is installed above the installation frame 207, and the installation shaft 208 is fixedly connected to the output shaft of the motor 212. First, the connection cover 8 is removed from the silage tank body 1, and then the forage is added to the silage tank body 1. Each time a certain amount of forage is added, the motor 212 can be started, and the output shaft of the motor 212 rotates to drive the installation shaft 208 to rotate, and the installation shaft 208 drives the installation rod 209 to rotate, so that the installation rod 209 drives the pressing plate 211 to rotate to the top of the silage tank body 1 through the connecting shaft 210, and then the motor 212 is started. The hydraulic rod 206 drives the mounting frame 207 to move downward when the telescopic end of the hydraulic rod 206 contracts. The mounting frame 207 causes the connecting shaft 210 to drive the pressing plate 211 to move downward. When the pressing plate 211 moves downward, the added forage can be compacted. The pressing plate 211 is driven by the hydraulic rod 206 to compact the forage, thereby improving the compaction efficiency. After compaction, the hydraulic rod 206 is extended, and then the motor 212 is started to rotate the pressing plate 211 to one side. The pressing plate 211 can be rotated to one side to avoid the pressing plate 211 affecting the addition of forage.

[0041] Specifically, Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig.13As shown, the mounting block 202 is fixed between the mounting structure 6 and the mounting sleeve 201, and the mounting structure 6 includes two fixing sleeves 601 fixedly connected to the side wall of the silage tank body 1 and a slide bar 602 slidably connected to the fixing sleeve 601, the slide bar 602 is slidably connected to the mounting sleeve 201, the slide bar 602 is engaged with the mounting block 202, a connecting block 603 is fixedly connected to the slide bar 602, a spring 604 is fixedly connected between the connecting block 603 and the fixing sleeve 601, a cross bar 605 is fixedly connected between the two sliding rods 602, a fixing block 606 is fixedly connected to the fixing sleeve 601 at the rear, a second knob 607 is slidably connected to the fixing block 606 at the rear, and the connecting block 603 at the rear is fixedly connected to the fixing sleeve 601. 03 is provided with a threaded hole 609 for use with a second knob 607, and a stopper 608 is fixedly connected to the second knob 607, and the stopper 608 conflicts with the fixed block 606. A winding structure 3 is provided on the base 205, and the winding structure 3 includes a vertical plate 301 fixedly connected to the top of the base 205 and a winding roller 302 fixedly connected to the front of the vertical plate 301, and a connecting plate 303 is fixedly connected to the winding roller 302, and a threaded column 304 is fixedly connected to the front of the winding roller 302. After the vacuum pump 506 is turned off, the connecting sleeve 503 can be removed from the threaded sleeve 502, and then the connecting sleeve 503 can be wound around the winding roller 302 on the vertical plate 301. After the winding is completed, the connecting sleeve 503 and the threaded column 304 are fixedly connected. The threaded fit of the column 304 fixes the connecting sleeve 503 and the connecting tube 504 to prevent the connecting tube 504 from sliding off the winding roller 302 after winding. At the same time, the setting of the connecting plate 303 can also prevent the connecting tube 504 from sliding off from the front of the winding roller 302. When the connecting tube 504 is wound up, the rear connecting block 603 can be pressed. When the connecting block 603 moves downward, the spring 604 contracts. At the same time, when the rear connecting block 603 moves downward, the rear sliding rod 602 is driven to move downward. The rear sliding rod 602 drives the front sliding rod 602 to move downward through the cross bar 605. When the sliding rod 602 is no longer engaged with the mounting block 202, the second knob 607 can be pushed to make the second knob 607 engage with the threaded hole 609 on the rear connecting block 603. The second knob 607 is then turned to make the second knob 607 threadably matched with the threaded hole 609 to fix the connecting block 603 to prevent the connecting block 603 from moving upward under the action of the spring 604. At this time, the vacuum pump 506, the hydraulic rod 206, the pressing plate 211 and other components can be moved to the side of other silage tank bodies 1 through the base 205, and the base 205 is fixed to the mounting sleeves 201 on other silage tank bodies 1 through the mounting block 202. The sliding rod 602 is engaged with the mounting block 202, so that the base 205 and the silage tank body 1 can be quickly disassembled and assembled, thereby improving the disassembly and assembly efficiency. The base 205 is detachable, so that it is convenient to drive the vacuum pump 506 and the pressing plate 211 to cooperate with multiple silage tank bodies 1 for use, thereby improving practicality.The connecting tube 504 is reeled in by the reeling roller 302 to prevent the excessively long connecting tube 504 from being damaged by friction with the ground when the base 205 moves.

[0042] Specifically, Figure 1 , Figure 3 , Figure 5 , Figure 7 , Fig. 9 , Fig.10 , Fig.12 , Fig.14 and Fig.15As shown, a sealing ring 505 is installed in the connecting sleeve 503, and the sealing ring 505 is in conflict with the threaded sleeve 502. The sealing structure 4 includes a sealing plate 401 slidably connected to the fixing frame 9 and a sealing ring 402 slidably connected to the sealing plate 401. A mounting plate 403 is slidably connected to the sealing plate 401, and the sealing ring 402 is fixedly connected to the mounting plate 403. A first knob 404 is rotatably connected to the sealing plate 401, and the mounting plate 403 is threadedly connected to the first knob 404. A sealing groove 406 is provided in the fixing frame 9. A guide column 405 is fixedly connected to the sealing plate 401, and the mounting plate 403 is slidably connected to the guide column 405. Both sides of the sealing plate 401 are fixedly connected There is an anti-slip block 407, and the anti-slip block 407 is slidably connected to the fixed frame 9. The filtering structure 7 includes a slide plate 701 detachably connected to the fixed frame 9 and a filter screen 702 fixedly connected to the slide plate 701. A card plate 703 is slidably connected in the fixed frame 9, and the card plate 703 is engaged with the slide plate 701. A pull plate 704 is fixedly connected above the card plate 703, and a tension spring 705 is fixedly connected between the pull plate 704 and the fixed frame 9. After the forage is added to the silage tank body 1, the connecting cover 8 is installed above the silage tank body 1, and the connecting sleeve 503 is threadedly matched with the threaded sleeve 502, and the connecting sleeve 503 is installed on the threaded sleeve 502. Since the connecting sleeve 503 is rotatably connected to the connecting pipe 504, it is not When the sealing plate 401 is no longer sealed at the through groove of the fixing frame 9, the vacuum pump 506 is started. When the vacuum pump 506 is in operation, the air inside the silage tank body 1 is extracted. If part of the forage is sucked up during the extraction, the forage will be filtered by the filter net 702. The filter net 702 is set to prevent the forage from coming out of the connecting pipe 504. The air in the silo tank body 1 is extracted by the vacuum pump 506. After the silo tank body 1 is sealed, the stored forage grass is isolated from the outside air, resulting in internal hypoxia and anaerobic fermentation, thereby producing organic acid, which can preserve the forage grass for a long time. At this time, turn the first knob 404, and the first knob 404 will threadably drive the mounting plate 403 to slide downward.The mounting plate 403 will slide with the guide column 405. The setting of the guide column 405 makes the mounting plate 403 slide more smoothly. The mounting plate 403 will drive the sealing ring 402 to move downward, so that the sealing ring 402 is engaged with the sealing groove 406 in the fixed frame 9. The sealing performance between the sealing plate 401 and the fixed frame 9 is improved by the engagement of the sealing ring 402 with the sealing groove 406. After the sealing plate 401 seals the through groove of the fixed frame 9, the vacuum pump 506 can be turned off, and when the filter screen 702 needs to be removed, the pull plate 704 can be pulled upward. When the pull plate 704 moves upward, the tension spring 705 extends. After the pull plate 704 drives the card plate 703 to slide until it is no longer engaged with the slide plate 701, the slide plate 701 can be pulled outward to remove the filter screen 702 for cleaning or replacement.

[0043] When the present invention is used, the connecting cover 8 is first removed from the silage tank body 1, and then the forage is added into the silage tank body 1. Each time a certain amount of forage is added, the motor 212 can be started, and the output shaft of the motor 212 drives the installation shaft 208 to rotate, and the installation shaft 208 drives the installation rod 209 to rotate, so that the installation rod 209 drives the pressing plate 211 to rotate to the top of the silage tank body 1 through the connecting shaft 210, and then the hydraulic rod 206 is started, and the telescopic end of the hydraulic rod 206 is retracted. When the hydraulic rod 206 is used to drive the pressing plate 211 to compact the forage grass, the hydraulic rod 206 is used to extend the hydraulic rod 206, and then the motor 212 is started to rotate the pressing plate 211 to one side. The pressing plate 211 can rotate to one side to avoid affecting the addition of forage grass.

[0044] After the forage is added into the silage tank body 1, the connecting cover 8 is installed on the silage tank body 1, and the connecting sleeve 503 is threadedly matched with the threaded sleeve 502, and the connecting sleeve 503 is installed on the threaded sleeve 502. Since the connecting sleeve 503 is rotatably connected with the connecting pipe 504, it will not affect the connecting pipe 504. When the connecting sleeve 503 moves to a certain position, the sealing ring 505 will contact with the threaded sleeve 502. The sealing ring 505 is tightly pressed against the threaded sleeve 502, thereby improving the sealing between the connecting sleeve 503 and the threaded sleeve 502. At this time, the sealing plate 401 is slid forward, and the sealing plate 401 drives the anti-slip block 407 to slide. The setting of the anti-slip block 407 can prevent the fixing frame 9 from slipping. When the sealing plate 401 no longer seals the through groove of the fixing frame 9, the vacuum pump 506 is started. When the vacuum pump 506 is in operation, the air inside the silage tank body 1 is extracted. If some forage is sucked up during the extraction, the forage will be filtered by the filter net 702. The setting of the filter net 702 can prevent the forage from entering the vacuum pump 506 from the connecting pipe 504 and causing damage to the vacuum pump 506. When the extraction is completed, the sealing plate 401 is pushed into the fixing frame 9. When it is pushed to a certain position, the sealing plate 401 seals the through groove of the fixing frame 9. After the air is extracted, , the sealing plate 401 slides to quickly seal the through groove of the fixing frame 9, thereby preventing the entry of oxygen and achieving a better silage effect, and the air inside the silage tank body 1 is extracted by the vacuum pump 506. After the silage tank body 1 is sealed, the stored forage is isolated from the external air, causing internal hypoxia and anaerobic fermentation, thereby producing organic acid, which can preserve the forage for a long time. At this time, the first knob 404 is turned, and the first knob 404 will threadably drive the mounting plate 403 to slide downward, and the mounting plate 403 will slide with the guide column 405. The setting of the guide column 405 makes the mounting plate 403 slide more smoothly, and the mounting plate 4 03 will drive the sealing ring 402 to move downward, so that the sealing ring 402 is engaged with the sealing groove 406 in the fixed frame 9. The sealing between the sealing plate 401 and the fixed frame 9 is improved by the engagement of the sealing ring 402 with the sealing groove 406. After the sealing plate 401 seals the through groove of the fixed frame 9, the vacuum pump 506 can be turned off, and when the filter screen 702 needs to be removed, the pull plate 704 can be pulled upward. When the pull plate 704 moves upward, the tension spring 705 extends. After the pull plate 704 drives the card plate 703 to slide until it is no longer engaged with the slide plate 701, the slide plate 701 can be pulled outward to remove the filter screen 702 for cleaning or replacement;

[0045] After the vacuum pump 506 is turned off, the connecting sleeve 503 can be removed from the threaded sleeve 502, and then the connecting sleeve 503 can be wound around the winding roller 302 on the vertical plate 301. After the winding is completed, the connecting sleeve 503 and the threaded column 304 are threadedly matched to fix the connecting sleeve 503 and the connecting pipe 504 to prevent the connected pipe 504 from sliding off the winding roller 302 after winding. At the same time, the setting of the connecting plate 303 can also prevent the connected pipe 504 from sliding off the front of the winding roller 302. When the connecting tube 504 is rolled up, the connecting block 603 at the rear can be pressed. When the connecting block 603 moves downward, the spring 604 contracts. At the same time, when the connecting block 603 at the rear moves downward, the sliding bar 602 at the rear moves downward. The sliding bar 602 at the rear drives the sliding bar 602 at the front to move downward through the cross bar 605. When the sliding bar 602 is no longer engaged with the mounting block 202, the second knob 607 can be pushed to connect the second knob 607 to the rear connecting block 603. The threaded hole 609 on the block 603 is contacted, and then the second knob 607 is rotated to make the second knob 607 threadedly matched with the threaded hole 609 to fix the connecting block 603 to prevent the connecting block 603 from moving upward under the action of the spring 604. At this time, the vacuum pump 506, the hydraulic rod 206, the pressing plate 211 and other components can be moved to the side of other silage tank bodies 1 through the base 205, and the base 205 is fixed to the mounting sleeve 201 on the other silage tank body 1 through the mounting block 202. The sliding rod 602 is engaged with the mounting block 202, so that the base 205 and the silage tank body 1 can be quickly disassembled and assembled, thereby improving the disassembly and assembly efficiency. The base 205 is detachable, so that it is convenient to drive the vacuum pump 506 and the pressing plate 211 to cooperate with multiple silage tank bodies 1 for use, thereby improving the practicality. The connecting pipe 504 is reeled in by the reeling roller 302 to prevent the excessively long connecting pipe 504 from rubbing against the ground when the base 205 moves and causing damage.
