Description

Technical Field

[0001] This application relates to silage baling technology, and more particularly to a forage storage and compaction device. Background Technology

[0002] The storage of livestock feed is mainly divided into two types: hay and silage. Silage preserves fresh feed through anaerobic fermentation. There are several storage methods for silage, including silage pits / pools, wrapped silage, and tower silage. Wrapped silage is made by squeezing out the moisture from the feed with a briquetting machine, compacting it into blocks, and then wrapping it with plastic film to isolate oxygen and promote lactic acid bacteria fermentation.

[0003] During the briquetting process of existing hay, leachate is generated and flows out from all sides of the briquette. However, during the briquetting process, the hay briquette is tightly fitted to the side walls and the pressure plate. The leachate generated on the side walls overflows upwards along the side walls of the briquetting chamber and cannot be quickly discharged through the opening in the bottom wall. After briquetting, it is necessary to wait for the overflowing leachate to flow downwards, which results in a long time from briquetting to bagging, affecting the briquetting efficiency of hay. Utility Model Content

[0004] This application provides a forage storage and compaction device to solve the problem of low discharge efficiency of leachate squeezed out during the compaction process of existing forage briquetting machines.

[0005] This application provides a forage storage and compaction device, including a compression chamber, with a hopper above the compression chamber. One end of the compression chamber is provided with a pressure plate that can move to the other end, and the other end is a pushing chamber. The front end of the pushing chamber is provided with a discharge port, and the rear end is provided with a push plate that slides toward the discharge port. The pressure plate and the push plate are driven by a hydraulic cylinder. The bottom wall of the compression chamber is provided with multiple rectangular openings. The front and rear ends of the compression chamber are vertically fixed with partitions that form seepage channels with their side walls. The seepage channels are connected to the openings. Perforated plates are fixed to the openings and the partitions.

[0006] Optionally, a collection box communicating with an opening is fixed to the bottom of the squeezing chamber, and a drain pipe is installed on the side of the collection box.

[0007] Optionally, a filter plate is provided at the lower end of the opening inside the collection box, and the top of the collection box is connected to the air intake of the negative pressure fan.

[0008] Optionally, the filter plate can be removed from one side of the collection box for cleaning.

[0009] Optionally, the upper end of the pressure plate is horizontally fixed with an interceptor plate for cutting off the extrusion chamber during pressing, and the edge of the interceptor plate facing the pressing chamber is a blade.

[0010] Optionally, a plurality of rotatably connected rollers are provided below the interceptor plate.

[0011] The forage storage and compaction device provided in this application forms a permeation channel at the side end by setting a partition on the side wall of the compression chamber. During the process of pushing and compressing the forage into briquettes, the leachate squeezed out from the sides of the forage can be quickly discharged into the permeation channel through the perforated plate on the partition, which improves the discharge efficiency of leachate and reduces the waiting time from briquettes to bagging.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0022] like Figures 1-6 As shown, one embodiment of this application provides a forage storage and compaction device, including a compression chamber 1, a hopper 2 above the compression chamber 1, a pressure plate 3 that can move to the other end at one end of the compression chamber 1, and a pushing chamber 5 at the other end. The front end of the pushing chamber 5 is provided with a discharge port 6, and the rear end is provided with a push plate 7 that slides toward the discharge port 6. The pressure plate 3 and the push plate 7 are driven by a hydraulic cylinder 4. The bottom wall of the compression chamber 1 is provided with a plurality of rectangular openings 8. The front and rear ends of the compression chamber 1 are vertically fixed with partitions 9 that form a seepage channel with the side walls. The seepage channel communicates with the openings 8. Perforated plates 10 are fixed on the openings 8 and the partitions 9.

[0023] In use, the forage enters the extrusion chamber 1 from the hopper 2. Inside the extrusion chamber 1, the hydraulic cylinder 4 pushes the pressure plate 3 towards the pressing chamber 5, compressing the forage into blocks. During the pressing process, the leachate squeezed out flows out through the perforated plates 10 on the bottom and side walls of the extrusion chamber 1. The leachate flowing out from the side wall enters the leachate channel and merges with the leachate flowing out from the bottom wall at the opening 8, then flows downwards. The forage blocks compacted by the pressure plate 3 enter the pressing chamber 5 and are pushed out from the discharge port 6 by the push plate 7 inside the pressing chamber 5.

[0024] In this embodiment, by setting a partition 9 on the side wall of the extrusion chamber 1 to form a permeation channel at the side end, the leachate squeezed out from the sides of the forage can be quickly discharged into the permeation channel through the perforated plate 10 on the partition 9 during the process of pushing and extruding the forage into a block, thereby improving the discharge efficiency of the leachate and reducing the waiting time from block to bagging.

[0025] In one possible implementation, a collection box 11 communicating with an opening 8 is fixed to the bottom of the squeezing chamber 1, and a drain pipe 12 is installed on the side end of the collection box 11.

[0026] The leachate, after converging through opening 8, flows downwards into collection tank 11 for storage. Once collection tank 11 is full, it is discharged into transfer tank through drain pipe 12. The leachate is rich in nitrogen, phosphorus, potassium, and organic matter, and can be diluted and used as liquid fertilizer for irrigating farmland and grassland, or as raw material for biogas production and microbial cultivation.

[0027] In one possible implementation, a filter plate 13 is provided at the lower end of the opening 8 inside the collection box 11, and the top of the collection box 11 is connected to the air intake of the negative pressure fan 14.

[0028] Filter plate 13 can filter out some impurity particles in leachate, improving the quality of leachate recovery.

[0029] In one possible implementation, the filter plate 13 can be removed from one side of the collection box 11 for cleaning.

[0030] The filter plate 13 is inserted through the through groove on the side of the collection box 11 and can be pulled out along the through groove for cleaning.

[0031] In one possible implementation, the upper end of the pressure plate 3 is horizontally fixed with an interceptor plate 15 for cutting off the extrusion chamber 1 when pressing the block, and the edge of the interceptor plate 15 facing the pressing chamber 5 is a blade.

[0032] As the pressure plate 3 moves to the other end to compress the straw, the upper fixed interceptor plate 15 can move synchronously with the pressure plate 3. While cutting the straw at the upper end of the compression chamber 1 with the blade, the interceptor plate 15 intercepts the straw in the upper hopper 2 to prevent the straw from falling to the other side of the pressure plate 3, which facilitates the pressing operation.

[0033] In one possible implementation, a plurality of rotatably connected rollers 16 are provided below the interceptor plate 15.

[0034] The idler roller 16 supports the portion of the interceptor plate 15 located outside the extrusion chamber 1.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
