Description

Technical Field

[0001] This utility model relates to the field of livestock breeding equipment technology, and in particular to a sealed silage pit with moisture-proof and frost-proof features. Background Technology

[0002] Silage is a type of roughage produced by chopping green fodder with a moisture content of 65% to 75% and fermenting it under sealed, oxygen-deficient conditions through the action of anaerobic lactic acid bacteria, which inhibits the growth of various miscellaneous bacteria. Silage pits are the main facilities for making and storing silage, and their sealing and heat preservation performance directly affects the fermentation quality and storage time of the silage.

[0003] However, existing silage pits are often designed in a simple way, covered only by simple cover plates or plastic films. This traditional sealing method is difficult to guarantee the airtightness between the edge of the pit and the cover. Especially during long-term use, the lack of a tight seal can easily allow external air and moisture to seep into the pit, destroying the internal anaerobic environment and causing aerobic spoilage and mold growth of the feed.

[0004] Furthermore, the fermentation process of silage requires a suitable temperature environment, and fermentation itself generates heat. However, in cold regions of northern my country or during winter, the ambient temperature is extremely low. Traditional silage pits lack effective heat preservation measures, causing heat to dissipate rapidly from the pit. This not only inhibits the activity of lactic acid bacteria and affects the fermentation quality, but also easily causes the feed in contact with the pit walls or top to freeze due to low temperatures. At the same time, the water vapor generated during fermentation rises and easily condenses into water droplets when it encounters the cold pit top, further aggravating the risk of spoilage of the surface feed. Existing single-structure silage pits can no longer meet the storage needs of modern livestock farming for high-quality feed.

[0005] Therefore, this utility model proposes a sealed silage pit with moisture-proof and freeze-proof features to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems in existing technologies, traditional silage pits have simple sealing structures that allow external moisture to easily seep in and cause feed to mold, as well as a lack of effective heat insulation measures that lead to rapid heat loss and easy freezing and spoilage of feed in low-temperature environments. This utility model aims to provide a sealed silage pit with improved structure that can effectively solve the above problems and is moisture-proof and freeze-proof.

[0007] This utility model provides a sealed silage pit with moisture-proof and freeze-proof features, comprising: a pit body and a sealing mechanism and a protective mechanism disposed on the outside of the pit body.

[0008] The protective mechanism has an outer shell that covers and is fixedly connected to the outside of the cellar body, and a vacuum groove for isolating heat conduction is formed between the outer wall of the cellar body and the inner wall of the outer shell.

[0009] Furthermore, the sealing mechanism includes a cellar cover that fits over the top of the cellar body. The bottom surface of the cellar cover has an interlocking groove. The top of the cellar body is embedded in the interlocking groove. A fixing plate is fixedly connected to the outer side of the cellar cover. A bolt is threaded onto the surface of the fixing plate. The bottom end of the bolt is fixedly connected to the outer wall of the outer shell. A wedge block is fixedly connected to the bottom surface of the cellar cover. A wedge groove is formed at the corresponding position on the top of the cellar body. The wedge block is inserted into the wedge groove, and the wedge block and the wedge groove are interference-fitted. Through the tight insertion of the wedge block and the wedge groove and the locking of the bolt, the cellar cover is firmly fixed above the cellar body and the internal environment of the cellar body is sealed.

[0010] Preferably, a rubber pad and a sealing pad are fixedly connected to the inner top wall of the fitting groove. The rubber pad and the sealing pad are located between the contact surface between the inner wall of the fitting groove and the top of the cellar body, and are used to fill the pores of the contact surface to enhance the sealing performance.

[0011] Preferably, a heat insulation plate is fixedly connected inside the vacuum tank. The heat insulation plate surrounds the outside of the cellar body and is located between the cellar body and the outer shell, in order to block the transfer of heat between the cellar body and the outside.

[0012] Preferably, the outer surface of the cellar cover and the outer surface of the outer shell are both covered with heat-insulating cloth, which covers the outermost layer of the sealing mechanism and the protective mechanism.

[0013] Preferably, the bottom surface of the cellar cover is fixedly connected with a second bolt, and a sponge board is sleeved on the outside of the second bolt. The sponge board is fixedly suspended at the bottom of the cellar cover by the second bolt and is used to absorb water vapor generated inside.

[0014] Preferably, the sponge board is located above the internal cavity of the cellar, and the two bolts are arranged at equal intervals on the bottom surface of the cellar cover.

[0015] Preferably, the bolts are arranged at equal intervals along the length of the fixing plate, and the fitting groove has a square frame structure to adapt to the top shape of the cellar body.

[0016] Preferably, the wedge-shaped blocks are arranged at equal intervals along the bottom edge of the cellar cover, and the number and position of the wedge-shaped grooves correspond one-to-one with the wedge-shaped blocks.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of poor sealing of the pit body and easy penetration of external moisture in the prior art by designing the pit cover, the interlocking groove, the interference fit of the wedge block and the wedge groove, and the multiple sealing structure of the rubber gasket and the sealing gasket. It achieves the effect of completely isolating the outside air and moisture, ensuring that the silage ferments in an anaerobic environment, and preventing the feed from getting damp, moldy and deteriorating.

[0019] 2. This utility model solves the problems of poor heat preservation performance and easy heat loss in existing silage pits by setting up a multi-layer protective mechanism consisting of an outer shell, a vacuum tank, a heat insulation board and a heat insulation cloth on the outside. It achieves the effect of efficient heat preservation and insulation, and prevents feed fermentation from being hindered or freezing and deteriorating in low-temperature environments.

[0020] 3. This utility model solves the problem of the hot and humid steam generated during feed fermentation rising to the top and condensing into water droplets or ice when it encounters cold air by setting a water-absorbing sponge board at the bottom of the cellar cover and fixing it with bolts. It achieves the effect of absorbing the water vapor at the top and preventing the condensate from dripping and contaminating or freezing the surface of the feed. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Please refer to Figures 1 to 5 This utility model provides a sealed silage pit with moisture and frost protection, which aims to solve the problems in the prior art where poor sealing performance of silage pits leads to easy penetration of external moisture and feed mold, and insufficient heat insulation performance leads to hindered feed fermentation or freezing and deterioration in low-temperature environments.

[0030] Please refer to Figure 1 and Figure 2 A moisture-proof and freeze-proof sealed silage pit includes a pit body 1, a sealing mechanism 2 and a protective mechanism 3 installed on the outside of the pit body 1. The pit body 1 serves as the main storage container for silage. The sealing mechanism 2 is used to cover and seal the top of the pit body 1 to block the air circulation between the external environment and the inside of the pit body 1. The protective mechanism 3 is used to cover the outer perimeter of the pit body 1 to reduce heat loss and prevent the effects of low temperature.

[0031] Please refer to Figure 1 , Figure 2 and Figure 4 The protective mechanism 3 includes an outer shell 301 that covers and is fixedly connected to the outside of the cellar body 1. A vacuum groove 306 is formed between the outer wall of the cellar body 1 and the inner wall of the outer shell 301. The vacuum groove 306 forms a heat insulation layer to reduce heat conduction. The sealing mechanism 2 includes a cellar cover 201 that covers the top of the cellar body 1. The bottom surface of the cellar cover 201 has a fitting groove 208. The top of the cellar body 1 is embedded in the fitting groove 208 to form a preliminary labyrinth-type sealing structure. Fixing plates 202 are fixedly connected to the left and right ends of the outer side of the cellar cover 201. Bolts 203 are threadedly connected to the surface of the fixing plates 202. The bottom end is fixedly connected to the outer wall of the outer shell 301. The cellar cover 201 is fastened to the outer shell 301 of the protective mechanism 3 by bolt 203. Wedge blocks 206 are fixedly connected to both the front and rear sides of the bottom of the cellar cover 201. A wedge groove 207 is opened at the corresponding position at the top of the cellar body 1. The wedge blocks 206 are inserted into the inside of the wedge groove 207 and the wedge blocks 206 and the wedge groove 207 are interference fit. Through the tight insertion of the wedge blocks 206 and the wedge groove 207 and the locking action of the bolt 203, the cellar cover 201 is firmly fixed above the cellar body 1 and provides multiple sealing protection for the internal environment of the cellar body 1.

[0032] Please refer to Figure 3 , Figure 4 and Figure 5 Rubber pad 204 and sealing pad 205 are fixedly connected to the inner top wall of the fitting groove 208. Rubber pad 204 and sealing pad 205 extend circumferentially along the fitting groove 208 and form a closed frame structure. Rubber pad 204 and sealing pad 205 are made of highly resilient rubber material. Rubber pad 204 and sealing pad 205 are arranged at predetermined positions on the inner wall of the fitting groove 208, contacting the top of the pit body 1. This provides a flexible buffer and sealing medium for the rigid connection between the pit body 1 and the pit cover 201. The top of the pit body 1 is correspondingly embedded inside the fitting groove 208. In the assembled state, the end face of the top of the pit body 1 directly presses against the rubber pad 204 and sealing pad 205. The axial pressure applied by the bolt 203 forces the rubber pad... The pad 204 and the sealing pad 205 undergo elastic compression deformation. The deformed rubber pad 204 and the sealing pad 205 fully fill the micro-assembly gap between the inner wall of the fitting groove 208 and the top of the cellar body 1. This flexible filling and fitting structure ensures that external air and moisture cannot pass through the joint surface between the cellar body 1 and the cellar cover 201 and enter the interior. In addition, the heat insulation plate 303 is fixedly connected to the inside of the vacuum tank 306. The heat insulation plate 303 surrounds the outer wall of the cellar body 1 and is located between the cellar body 1 and the outer shell 301. The heat insulation plate 303 blocks heat radiation and heat convection. Together with the vacuum environment of the vacuum tank 306, it forms a double heat insulation barrier to ensure that the heat inside the cellar body 1 is not easily lost and is not easily affected by the external low temperature.

[0033] As a preferred embodiment, to further improve the overall thermal insulation effect of the device and prevent external cold air from directly contacting metal components and causing accelerated heat conduction, please refer to... Figure 5 The outer surface of the cellar cover 201 and the outer surface of the outer shell 301 are both covered with heat insulation cloth 302. The heat insulation cloth 302 is tightly attached to the outermost surface of the sealing mechanism 2 and the protective mechanism 3. The heat insulation cloth 302 is made of industrial heat insulation felt or heat insulation cotton with low thermal conductivity. The heat insulation cloth 302 forms a windproof and heat barrier on the outermost layer of the device, reducing the impact of the external ambient temperature on the inside of the cellar 1.

[0034] As another preferred embodiment, to prevent high-temperature water vapor generated during silage fermentation from rising to the top, condensing into water droplets upon cooling, and dripping onto the feed surface, causing freezing or localized mold growth, please refer to... Figure 1 and Figure 3 Bolts 305 are fixedly connected to the left and right sides of the bottom surface of the cellar cover 201. A sponge board 304 is sleeved on the outside of the bolts 305. The sponge board 304 is fixed and suspended on the bottom plane of the cellar cover 201 by the bolts 305. The sponge board 304 is horizontally positioned directly above the internal cavity of the cellar body 1. The bolts 305 are evenly distributed on the bottom surface of the cellar cover 201. The multi-point support method ensures that the sponge board 304 remains flat and does not fall. The porous water absorption characteristics of the sponge board 304 are used to absorb the water vapor rising to the top.

[0035] As another preferred embodiment, to ensure uniform stress distribution in the sealed connection structure and improve connection stability, please refer to... Figure 2 and Figure 4 Bolts 203 are arranged at equal intervals along the length of the fixing plate 202. The fixing plate 202 can evenly transmit the locking force to the contact surface between the cellar cover 201 and the cellar body 1 through the equally spaced locking points. The fitting groove 208 has a square frame structure to fit the rectangular opening shape at the top of the cellar body 1. The wedge blocks 206 are arranged at equal intervals along the bottom edge of the cellar cover 201. The number and position of the wedge grooves 207 correspond one-to-one with the wedge blocks 206, ensuring that each wedge block 206 can be accurately inserted into the corresponding wedge groove 207 during the closing process of the cellar cover 201.

[0036] Working principle:

[0037] When sealing silage, the operator aligns the silage cover 201 with the top of the silage body 1 and closes it. As the silage cover 201 moves downward, the wedge-shaped block 206 on the bottom of the silage cover 201 is accurately inserted into the wedge-shaped groove 207 at the top of the silage body 1. Due to the interference fit design between the wedge-shaped block 206 and the wedge groove 207, the wedge-shaped block 206 is forced into the wedge groove 207, generating a strong lateral locking force. At the same time, the top of the silage body 1 is completely embedded in the bottom fitting groove 208 of the silage cover 201, and the top end face of the silage body 1 tightly presses against the fitting groove. The internal rubber gasket 204 and sealing gasket 205 are connected by rotating the fixing plate 202 and the surface bolt 203. The bolt 203 is screwed into the outer wall of the outer shell 301 and a downward pulling force is applied. This pulling force further compresses the rubber gasket 204 and sealing gasket 205, forcing the rubber gasket 204 and sealing gasket 205 to undergo elastic deformation and fill the tiny gap at the connection between the pit body 1 and the pit cover 201. This mechanical locking and flexible gap-filling structure completely blocks the path of external humid air into the pit body 1, ensuring that the silage is fermented in a strictly sealed anaerobic environment.

[0038] During the fermentation and long-term storage of silage, when the ambient temperature drops below freezing, the protective mechanism 3 plays a role in heat insulation. The outer shell 301 covering the outer shell 301 of the silo body 1 forms a vacuum trough 306 between the silo body 1 and the outer shell 301, effectively cutting off the heat conduction path. The heat insulation plate 303 located inside the vacuum trough 306 further blocks heat radiation and heat convection. Combined with the outermost layer of heat insulation cloth 302, the multi-layer heat insulation structure locks the heat generated by fermentation inside the silo body 1 and blocks the intrusion of cold air from the outside, preventing the feed from freezing and deteriorating due to low temperature. At the same time, in response to the situation where high-temperature water vapor rises and accumulates at the top during the fermentation process, the sponge board 304 suspended at the bottom of the silo cover 201 uses a porous structure to actively absorb water vapor, preventing water vapor from condensing into ice droplets on the inner wall of the silo cover 201 and falling back onto the feed surface.
