Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and more specifically, to a feed silage device. Background Technology

[0002] In animal husbandry, silage technology is a key technology to ensure a year-round supply of forage. Traditional silage equipment has difficulty in venting gas during the compaction process, resulting in residual air inside the feed that hinders anaerobic fermentation, provides a living environment for harmful aerobic microorganisms, and causes feed spoilage and nutrient loss. The simple compaction method and the single, easily clogged exhaust channel make compaction inefficient and unable to meet the needs of large-scale farms.

[0003] During the storage of silage, existing equipment lacks a reliable sealing mechanism, allowing outside air to easily seep in through the exhaust channels, disrupting the anaerobic environment and causing mold growth at the edges and rot in the center of the feed.

[0004] In addition, traditional equipment cannot automatically coordinate the compaction and degassing processes, requiring frequent manual adjustments, which increases labor intensity and makes it difficult to ensure standardized operation, thus affecting the quality of silage and the efficiency of breeding. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a feed silage device to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a silage device, comprising a silo body and a top cover, wherein the top cover is installed on the top of the silo body, a hydraulic cylinder is fixedly mounted on the top surface of the top cover, a pressure plate is fixedly mounted on the piston end of the hydraulic cylinder, the pressure plate slides on the inner wall of the silo body, and the pressure plate has through holes, wherein multiple sets of through holes are provided, and each of the through holes has an exhaust mechanism on its top surface, the exhaust mechanism comprising a connecting sleeve and a sealing plate, the connecting sleeve being fixed on the top surface of a push plate, the sealing plate being fixed inside the connecting sleeve and slidably connected to a push block, a sliding rod being fixedly mounted on the bottom surface of the push block, a push plate being fixedly mounted on the bottom end of the sliding rod, a top plate being fixedly mounted on the top of the connecting sleeve, a movable groove being provided between the top plate and the sealing plate, and a sealing block being slidably mounted in the movable groove, wherein multiple sets of sealing blocks are provided and each of them abuts against the push block.

[0007] The present invention is further configured such that a limiting sleeve is fixedly provided on the inner side of the connecting sleeve, the limiting sleeve is slidably connected to the slide rod, and the slide rod is configured as a polygon to prevent the slide rod from rotating during movement, ensuring a stable connection between the push block and the sealing block, and improving the reliability and working accuracy of the exhaust mechanism.

[0008] The present invention is further configured such that a vent hole is provided at the bottom end of the connecting sleeve, and the push plate abuts against the vent hole to form an automatically opening and closing exhaust channel so that the gas can be discharged in one direction and can be automatically sealed after the exhaust is completed to prevent the outside air from flowing back and ensure the anaerobic fermentation environment.

[0009] The present invention is further configured such that a ball bearing is rotatably provided on the outer side of the push plate, and multiple sets of the ball bearing are provided. An arc-shaped groove is opened on the inner side of each set of the sealing block, and the multiple sets of the arc-shaped groove abut against the multiple sets of the ball bearing respectively, thereby reducing the friction between the push plate and the contact surface of the chamber and improving the sensitivity of the exhaust mechanism so that it can start and maintain stable operation under lower air pressure.

[0010] The present invention is further configured such that a return spring is connected between the outer side of the multiple sets of sealing blocks and the movable groove. The multiple sets of return springs provide an automatic return force for the sealing blocks to ensure that the airflow channel can be quickly closed after the exhaust is completed, forming a reliable seal to prevent outside air from entering.

[0011] The present invention is further configured such that guide blocks are fixedly provided on the bottom surface of the multiple sets of sealing blocks, and guide grooves are provided on the top surface of the sealing plate. The guide grooves are provided in multiple sets and are slidably connected to the multiple sets of guide blocks respectively, providing precise motion guidance to ensure that the sealing blocks move smoothly along the predetermined trajectory, preventing jamming and deviation, and ensuring that the exhaust process is continuous and reliable.

[0012] The present invention is further configured such that the top cover and the top of the silo body are detachable, which facilitates the feeding and removal of feed, and also facilitates the cleaning and maintenance of the equipment, thereby improving work efficiency and service life.

[0013] The present invention is further configured such that the top cover is provided with an exhaust hole, and multiple sets of exhaust holes are provided to provide a final exhaust channel to ensure that the gas discharged during the feed compaction process can be completely discharged outside the equipment, thereby improving the silage effect and feed quality.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a silage device with the following advantages: 1. This device features an innovative, highly efficient, and automated exhaust mechanism. By setting multiple sets of through holes on the pressure plate and equipping it with an intelligent exhaust system consisting of a connecting sleeve and a sealing plate, it achieves directional gas discharge during the compaction process. When the feed is compressed, the resulting air pressure automatically pushes the push plate away from the vent hole and, through the slide rod and push block, drives the sealing block to form an airflow channel in the movable trough. This allows residual air in the feed to be quickly discharged without being blocked, effectively solving the problems of poor anaerobic fermentation and feed spoilage caused by the difficulty in exhausting traditional silage devices. This significantly improves the efficiency and quality of the silage process.

[0015] 2. This device is equipped with a precise and reliable sealing system. The sliding connection between the polygonal slide rod and the limiting sleeve prevents rotation and ensures stability. At the same time, the combination of multiple sets of ball bearings and arc grooves reduces friction and improves sensitivity. A specially designed sealing block combination mechanism with a return spring realizes the automatic sealing function after exhaust. When the air in the bin is completely exhausted, the return spring automatically pushes the sealing block to reset and close the movable groove. At the same time, it drives the push plate to abut against the air vent to form a double sealing structure. This effectively prevents the problem of external air seeping back and destroying the anaerobic environment. It fundamentally eliminates the risk of feed mold and spoilage caused by poor sealing in traditional devices.

[0016] 3. This device adopts an integrated design that coordinates compaction and degassing. It uses a hydraulic cylinder to drive the pressure plate for efficient and uniform feed compaction while triggering the automatic operation of the degassing mechanism. The sliding connection between the guide block and the guide groove ensures that the sealing block moves smoothly and reliably. The entire system forms a complete and efficient operation process from feeding and compaction to gas discharge and automatic sealing. Operators only need to start the hydraulic cylinder to complete all processes without frequent manual adjustments. This not only greatly improves work efficiency and reduces labor intensity, but also ensures the consistent quality and storage stability of silage through standardized operation, providing reliable feed supply and economic benefits for large-scale livestock farming.
