Technical Field

[0001] The present invention relates to the technical field of Pennisetum silage, and more particularly, to a Pennisetum forage silage fermentation system. Background Art

[0002] Forage silage is an effective means to extend the storage time of forage and improve the feeding effect of forage. However, in traditional forage silage work, silage failure (rotting and deterioration) often occurs. Since it is usually batch and large-scale silage, once this situation occurs, it is very easy to cause a large amount of forage waste.

[0003] Due to the usually batch and large-scale silage, traditional manual monitoring is no longer applicable, and it is very easy to have problems of inadequate monitoring.

[0004] In view of this, the present application is specifically proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a Pennisetum forage silage fermentation system, which can continuously sample and monitor the fermentation system during the silage process to ensure the smooth progress of the silage fermentation process, facilitate the timely treatment of the fermentation system with abnormal fermentation, further reduce the loss of forage, and improve the utilization rate of forage.

[0017] On one side of the sliding member close to the collection hole, a collection inner tank is provided, and the collection inner tank is cylindrical. One end of the collection inner tank is fixedly connected to the sliding member, and one end of the collection inner tank close to the sliding member is closed by the sliding member. The other end of the collection inner tank is fixedly connected to the inner end wall of one end of the collection inner cavity close to the collection hole, and one end of the collection inner tank far from the sliding member is closed by the inner end wall of the collection inner cavity.

[0018] The sliding member is also equipped with a collection pipe. The collection pipe is located on the side of the sliding member far from the collection inner tank. The collection pipe penetrates through the sliding member and is fixedly connected to the sliding member. The collection pipe is communicated with the internal space of the collection inner tank. The collection pipe is made of a flexible material. One end of the collection pipe far from the sliding member is led out from one end of the cooperation column far from the rotating ring and further extends outside the cover.

[0020] Further, a groove is provided on the inner end wall of the collection inner cavity close to the rotating ring, the collection hole is provided in the groove, and the diameter of the groove is greater than the diameter of the baffle. When the one-way valve is closed, the baffle fits against the bottom of the groove.

[0021] Further, the controller is used to determine the molar amount of the sampled gas collected this time according to the distance between the pushing member and the end face of the cooperation column when the one-way valve is opened.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] In order to overcome the defects existing in the prior art, please refer to Figures 1-6 , this embodiment provides a Pennisetum forage silage fermentation system, and the Pennisetum forage silage fermentation system includes: a fermentation container 100, a gas sampling mechanism 200, and a controller (not shown in the figure).

[0038] The fermentation container 100 is used to put silage raw materials for silage fermentation.

[0039] The top of the fermentation container 100 has an opening and is detachably fitted with a cover 110, and the gas sampling mechanism 200 is arranged inside the cover 110.

[0040] The gas sampling mechanism 200 includes: a rotating ring 210, a fitting cylinder 220, a telescopic assembly 230, and a fitting column 240.

[0041] The rotating ring 210 is rotatably fitted to the cover 110 and driven by a driver (not shown in the figure). The rotation axis line of the rotating ring 210 is arranged along the radial direction of the opening of the fermentation container 100. The axis line of the fitting cylinder 220 is arranged parallel to the rotation axis line of the rotating ring 210, and the fitting cylinder 220 is fixedly connected to the inner ring wall of the rotating ring 210.

[0042] The rotation axis line of the rotating ring 210 coincides with its central axis line. Along the length direction of the central axis line of the rotating ring 210, the telescopic assembly 230 and the fitting column 240 are arranged on opposite sides of the rotating ring 210.

[0043] The telescopic rod 231 of the telescopic assembly 230 is arranged parallel to the rotation axis line of the rotating ring 210 and fixedly connected with a pushing member 232. The shape of the pushing member 232 is the same as the cross-sectional shape of the inner space of the fitting cylinder 220, and the diameter of the pushing member 232 is adapted to the inner diameter of the fitting cylinder 220.

[0044] The fitting column 240 is arranged coaxially with the telescopic rod 231. The fitting column 240 has a collecting inner cavity 241, and the collecting inner cavity 241 extends along the length direction of the fitting column 240. A collecting hole 242 communicating with the collecting inner cavity 241 is formed in the end wall of the fitting column 240 close to the rotating ring 210. The collecting hole 242 is fitted with a one-way valve 300 and a detecting assembly 400 for detecting whether the one-way valve 300 is opened. The one-way valve 300 is in a normally closed state, and the one-way valve 300 can be opened from the collecting hole 242 to the side where the collecting inner cavity 241 is located, so that the collecting hole 242 communicates with the collecting inner cavity 241.

[0045] In this embodiment, when the telescopic rod 231 is in the retracted state, the distance between the pushing member 232 and the fitting column 240 is greater than or equal to the length of the fitting cylinder 220. Optionally, the distance between the pushing member 232 and the fitting column 240 is equal to the length of the fitting cylinder 220. That is to say, a space for the fitting cylinder 220 to pass through is left between the pushing member 232 and the fitting column 240.

[0046] During the rotation of the rotating ring 210, the fitting cylinder 220 moves with the rotation of the rotating ring 210. During the movement of the fitting cylinder 220, the fitting cylinder 220 will periodically enter the matching state.

[0047] When the mating cylinder 220 is in a matching state, the telescopic rod 231, the mating cylinder 220, and the mating column 240 are coaxially arranged, and the end face of the mating cylinder 220 is in contact with the end face of the mating column 240, that is, the mating column 240 closes the end of the mating cylinder 220 away from the telescopic mechanism at this time. At this time, by controlling the telescopic rod 231 to extend, the telescopic mechanism can push the pushing member 232 into the mating cylinder 220. Among them, there is a sliding seal relationship between the pushing member 232 and the mating cylinder 220. During the process of the pushing member 232 approaching the mating column 240 through the mating cylinder 220, the gas in the mating cylinder 220 is continuously compressed, and the air pressure in the mating cylinder 220 continuously increases. When the air pressure reaches the threshold value that can push open the one-way valve 300, the one-way valve 300 is successfully pushed open, so that the gas in the mating cylinder 220 can enter the collection cavity 241 through the collection hole 242. After the gas in the mating cylinder 220 is fully sent into the collection cavity 241, the one-way valve 300 resets, and the gas is sealed in the collection cavity 241. In this way, a sampling of the gas in the fermentation container 100 is completed.

[0048] The gas collected in the collection cavity 241 can be exported through a pipeline for detection and analysis, so that technicians can judge whether the silage process is qualified by analyzing the changes in the gas components during the silage process, and it is convenient to detect abnormal situations in the fermentation process in a timely manner.

[0049] Among them, a distance sensor (not shown in the figure) for detecting the distance between the end face of the pushing member 232 and the end face of the mating column 240 is arranged on the side of the pushing member 232 close to the mating column 240. The distance sensor and the detection component 400 are both electrically connected to the controller, and the controller is used to determine the air pressure in the fermentation container 100 according to the distance between the pushing member 232 and the end face of the mating column 240 when the one-way valve 300 is opened.

[0050] Specifically, since the pressure required to open the one-way valve 300 is certain, when the one-way valve 300 is just pushed open, it means that the air pressure in the mating cylinder 220 at this moment is equal to this threshold pressure. At this time, according to the current distance between the pushing member 232 and the end face of the mating column 240, as well as the initial distance between the end faces of the pushing member 232 and the mating column 240, the compression degree (compression ratio) of the gas in the mating cylinder 220 when the threshold pressure is reached can be determined, and thus the pressure of the gas in the mating cylinder 220 when it is not compressed can be calculated in reverse, and this pressure is equal to the air pressure in the fermentation container 100.

[0051] Through the above design, not only can it be judged whether the silage process is qualified by automatically sampling the gas in the fermentation container 100, but also the air pressure in the fermentation container 100 can be verified and confirmed to ensure the safety of the silage process.

[0052] Optionally, the distance sensor can be a laser ranging sensor, and is not limited thereto.

[0053] It should be noted that during the silage fermentation process, the time interval for gas sampling can be flexibly adjusted according to actual needs. During the interval between each sampling, the rotating ring 210 can be controlled to keep rotating all the time, which is beneficial to disturbing the gas in the fermentation container 100 with the cooperation cylinder 220, ensuring the uniformity of the gas, thereby improving the credibility of sampling. At the same time, it is also beneficial to keep the gas in the cooperation cylinder 220 highly consistent with the gas in the fermentation container 100, thereby reducing the sampling error.

[0054] Generally speaking, the forage grass silage fermentation system of the genus Pennisetum provided in this embodiment can continuously sample and monitor the fermentation system during the silage process to ensure the smooth progress of the silage fermentation process, facilitate timely treatment of the fermentation system with abnormal fermentation, further reduce the loss of forage grass, and improve the utilization rate of forage grass.

[0055] The forage grass silage fermentation system of the genus Pennisetum further includes: a pressing plate 600 and a stop block 700.

[0056] The pressing plate 600 is a mesh plate, and the pressing plate 600 is used to be placed in the fermentation container 100 to compact the silage raw materials in the fermentation container 100.

[0057] The stop block 700 is detachably fitted to the inner wall of the fermentation container 100 and there is a spacing between the stop block 700 and the mouth of the fermentation container 100. The stop block 700 abuts against one side of the pressing plate 600 close to the mouth of the fermentation container 100 to limit the pressing plate 600 within the fermentation container 100.

[0058] The gas sampling mechanism 200 is arranged at an interval from the pressing plate 600.

[0059] Specifically, in this embodiment, the one-way valve 300 includes: a core body 310, a support bar 320 and a baffle 330.

[0060] The support bar 320 is fixedly connected to the outer side wall of the core body 310 and extends along the length direction of the core body 310. A plurality of support bars 320 are evenly spaced along the circumferential direction of the core body 310. The core body 310 is slidably fitted in the collection hole 242, and the core body 310 is attached to the hole wall of the collection hole 242 through the support bar 320.

[0061] The baffle 330 is perpendicular to the core body 310 and is fixedly connected to one end of the core body 310 away from the rotating ring 210. The baffle 330 is located in the collection cavity 241, and the diameter of the baffle 330 is larger than the diameter of the collection hole 242.

[0062] The detection component 400 includes: a reference column 410, a conductive core 440 and a detection circuit (not shown in the figure).

[0063] The reference column 410 is disposed in the collection inner cavity 241 and fixedly connected to the inner wall of the mating column 240. The reference column 410 is arranged along the axial direction of the collection hole 242. The collection hole 242, the mating column 240, the collection inner cavity 241, and the reference column 410 are coaxially arranged.

[0064] A gap is left between the reference column 410 and the collection hole 242. A mating blind hole 420 is formed in the end wall of the reference column 410 close to the collection hole 242, and the mating blind hole 420 extends along its length direction. The conductive core 440 is slidably fitted in the mating blind hole 420. The diameter of the conductive core 440 is adapted to the aperture of the mating blind hole 420. An elastic member 450 is abutted between the conductive core 440 and the bottom wall of the mating blind hole 420. In the natural state, under the action of the elastic member 450, the conductive core 440 abuts against the baffle 330, and the baffle 330 fits against the inner end wall of the collection inner cavity 241, thereby making the one-way valve 300 in a normally closed state.

[0065] Conductive contacts 430 are provided on the side wall of the mating blind hole 420. The conductive contacts 430 are arranged close to the mouth of the mating blind hole 420. The conductive contacts 430 are in contact with and electrically connected to the conductive core 440. One pole of the conductive contacts 430 is connected to the detection circuit by a first wire 460, and one end of the conductive core 440 away from the baffle 330 is connected to the other pole of the detection circuit by a second wire 470.

[0066] The baffle 330, the elastic member 450, and the reference column 410 are all made of insulating materials.

[0067] When the one-way valve 300 is opened, the baffle 330 will push the conductive core 440 into the mating blind hole 420, resulting in the conductive contacts 430 being relatively closer to the end of the conductive core 440 close to the baffle 330, thereby increasing the actual length of the conductive core 440 connected to the detection circuit and increasing the resistance. Therefore, it is possible to judge whether the one-way valve 300 is opened by monitoring the current or the total resistance value of the detection circuit, and it is not limited to this.

[0068] Furthermore, a sliding member 500 is arranged in the collection inner cavity 241. The sliding member 500 is provided with a relief hole for the reference column 410 to pass through. Along the length direction of the mating column 240, the sliding member 500 is slidably fitted in the collection inner cavity 241. A sliding seal is provided between the sliding member 500 and the inner side wall of the mating column 240, and between the sliding member 500 and the reference column 410.

[0069] On one side of the sliding member 500 close to the collection hole 242, there is a collection inner bladder 510. The collection inner bladder 510 is made of a flexible material. In its natural state, the collection inner bladder 510 is in a cylindrical shape. One end of the collection inner bladder 510 is fixedly connected to the sliding member 500, and one end of the collection inner bladder 510 close to the sliding member 500 is closed by the sliding member 500. The other end of the collection inner bladder 510 is fixedly connected to the inner end wall of one end of the collection inner cavity 241 close to the collection hole 242, and one end of the collection inner bladder 510 far from the sliding member 500 is closed by the inner end wall of the collection inner cavity 241.

[0070] Sliding the sliding member 500 towards the end where the collection hole 242 is located can compress the collection inner bladder 510.

[0071] The sliding member 500 is also equipped with a collection tube 520. The collection tube 520 is located on the side of the sliding member 500 far from the collection inner bladder 510. The collection tube 520 penetrates through the sliding member 500 and is fixedly connected to the sliding member 500. The collection tube 520 is in communication with the internal space of the collection inner bladder 510.

[0072] The collection tube 520 is made of a flexible material. One end of the collection tube 520 far from the sliding member 500 is led out from one end of the mating post 240 far from the rotating ring 210 and further extends outside the cover 110 (when extending outside the cover 110, it is necessary to ensure airtightness). The outer end of the collection tube 520 can be connected to a gas collector or a gas analysis device for collecting and analyzing the collected gas samples.

[0073] The collection hole 242 is also in communication with the internal space of the collection inner bladder 510. An outlet 243 for the collection tube 520 to extend out is provided on the end face of one end of the mating post 240 far from the collection hole 242. The diameter of the outlet 243 is larger than the diameter of the collection tube 520.

[0074] Among them, when the gas in the mating cylinder 220 is pushed into the collection inner cavity 241 from the collection hole 242, the gas enters the collection inner bladder 510. The collection inner bladder 510 expands and pushes the sliding member 500 towards the end far from the collection hole 242, thereby realizing gas collection.

[0075] When the gas collection is completed, the one-way valve 300 resets and closes, and the gas is sealed in the collection inner bladder 510. At this time, by directly extracting the gas through the collection tube 520, the gas can be extracted. During the process of gas extraction, as the gas is extracted, the air pressure in the collection inner bladder 510 decreases, and the sliding member 500 will gradually slide towards the side where the collection hole 242 is located and gradually reset.

[0076] Optionally, the thickness of the sliding member 500 is greater than the distance between the reference post 410 and the collection hole 242.

[0077] Optionally, a groove is provided in the collection lumen 241 near the inner end wall of the rotating ring 210, the collection hole 242 is provided in the groove, and the diameter of the groove is larger than the diameter of the baffle 330. When the one-way valve 300 is closed, the baffle 330 fits against the bottom of the groove.

[0078] Further, the controller is configured to determine the molar amount of the sampled gas collected this time (calculated according to the air pressure and the volume of the mating cylinder 220) based on the distance between the pushing member 232 and the end face of the mating post 240 when the one-way valve 300 is opened.

[0079] The Pennisetum forage silage fermentation system further includes: a gas supplementing component (not shown in the figure). The gas supplementing component is configured to supplement a corresponding amount of inert gas into the fermentation container 100 according to the molar amount of the sampled gas.

[0080] In this way, the air pressure inside the fermentation container 100 can be kept stable. Even if sampling is performed multiple times, the internal air pressure will not be affected, which is beneficial to maintaining the use safety of the fermentation container 100.

[0081] In summary, the Pennisetum forage silage fermentation system provided by the embodiments of the present invention can continuously sample and monitor the fermentation system during the silage process to ensure the smooth progress of the silage fermentation process, facilitate timely treatment of the fermentation system with abnormal fermentation, further reduce the loss of forage, and improve the utilization rate of forage.

[0082] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
