Description

Technical Field

[0001] This invention relates to the field of silage processing technology, specifically to a silage processing equipment. Background Technology

[0002] Existing processing equipment for pelleted silage mainly includes feeding devices for feeding silage raw materials and pellet mills for rolling and pelletizing the incoming materials.

[0003] Because silage raw materials have a high moisture content, direct pelleting yields poor results. Therefore, it's necessary to pre-mix some dry powder, such as crushed wheat bran or corn flour, into the silage raw materials before pelleting to improve pelleting efficiency. Existing pelleting equipment typically uses roller-type pellet mills. After the silage raw materials mixed with dry powder are fed into the pellet mill, the rotating feed rollers compress the silage raw materials on the forming disc, forcing them through the forming holes for pelleting. However, in actual pelleting, the excessive friction of the material passing through the forming holes during extrusion makes extrusion difficult, affecting the pelleting effect and reducing pelleting efficiency. Furthermore, the extruded pellets easily break into fragments upon breaking, which cannot be promptly removed and collected, resulting in a large amount of fragments in the finished pellets, affecting feed stability and palatability.

[0004] Therefore, the research objective of this invention is to design a silage processing equipment that can uniformly and conveniently add dry powder to silage raw materials during the feeding process; effectively and significantly improve the granulation efficiency and granulation effect of silage during the pelleting process; and promptly clean and collect the feed fragments formed during the pelleting process, thereby ensuring the stability and palatability of the pelleted feed. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a silage processing equipment that can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is: A silage processing device includes a pelletizer for pelleting silage and a feeding device for feeding raw materials into the pelletizer. The granulator includes: A feed pelleting chamber is set on a corresponding machine base. A feed forming disc adapted to pelletize feed raw materials is installed in the feed pelleting chamber. The feed forming disc is evenly provided with a number of feed pelleting holes for extruding feed raw materials into pellets. A feed forming assembly includes a feed forming tube fixed to the feed pelleting hole. The bottom of the feed forming tube is open and facing downwards, and a corresponding feed pellet isolation cover is provided. The feed pellet isolation cover is connected to a corresponding feed isolation plate, and feed pellet guide holes for feed fragments are evenly distributed on the feed pellet isolation cover. A corresponding ultrasonic vibrator is connected to the feed isolation plate to assist the forming of feed raw materials in the feed forming tube through ultrasonic vibration. A corresponding feed fragment extraction pipe is provided in the space formed by the feed isolation plate, the feed forming plate, and the feed pellet isolation cover. The feed fragment extraction pipe is used to discharge feed fragments generated during the pelleting process. The feed roller pressing assembly includes a mounting shaft rotatably disposed within the feed pelleting chamber. The upper end of the mounting shaft extends through to the upper part of the feed forming disc and is horizontally rotatably mounted with at least one rolling feed roller pressing component adapted for feed raw material pelleting. The mounting shaft is drively connected to the output shaft end of a corresponding drive motor to drive the rolling feed roller pressing component to rotate in order to extrude and pelletize the feed raw materials on the feed forming disc. The feeding device includes: The feeding channel is supported and installed on the corresponding feeding bracket. The discharge end of the feeding channel is directly opposite the upper side of the feed pelleting chamber. A silage feeding hopper is installed on the side of the feeding channel away from the discharge end, and a dry powder feeding hopper is provided on the side of the feeding channel close to the discharge end. The silage pushing assembly is used to push the silage raw materials in the feeding channel toward its discharge end; The cutting and mixing assembly is used to cut the silage material passing under the dry powder hopper and mix the dry powder into the cut silage material.

[0007] The silage pushing assembly includes a reciprocating pushing cylinder installed on the feeding channel at the rear of the silage feeding hopper. The piston rod end of the reciprocating pushing cylinder extends into the feeding channel at the rear of the silage feeding hopper and is fixedly connected to a corresponding pushing plate.

[0008] The dry powder hopper is equipped with a corresponding buffer rubber component at the discharge port. The cutting and mixing assembly includes a lifting drive cylinder that can be lifted and installed on the upper side of the dry powder hopper. An ultrasonic cutter with a blade penetrating through the opening of the buffer rubber component is fixed downward to the lifting drive cylinder.

[0009] The portion of the feed forming tube not connected to the feed pelleting hole is spaced apart from the feed pelleting hole. Corresponding vibration-damping rubber tubes are extruded and installed at the intervals between the feed forming tube and the feed pelleting hole. During the process of driving the rolling feed roller to rotate and press the material on the upper side of the feed forming disc into the corresponding feed pelleting hole for pelleting, the ultrasonic vibrator is activated so that each feed forming tube is independently under ultrasonic vibration.

[0010] A corresponding transverse cutting component is fixedly installed on the mounting shaft on the lower side of the feed isolation plate. The feed scrap extraction pipe is connected to the feed end of the corresponding negative pressure collection component. When the transverse cutting component cuts the formed material as the mounting shaft rotates, the negative pressure collection component is activated to draw negative pressure into the space formed by the feed isolation plate, the feed forming disc, and the feed pellet isolation cover, so as to collect the scrap caused by cutting under negative pressure. During the negative pressure collection of scrap, the inner surfaces of the feed isolation plate, the feed forming disc, and the feed pellet isolation cover are respectively under the drive of the ultrasonic vibrator in an ultrasonic vibration state.

[0011] The upper part of the feed pelleting chamber is provided with a corresponding feed guide hopper, and a filter media assembly for screening the feed raw materials by particle size is installed on the feed guide hopper; the filter media assembly includes a filter screen installed on the feed guide hopper, the filter screen is made of elastic metal material, and a corresponding feed guiding area is provided in the middle of the filter screen. Multiple corresponding protrusions are evenly distributed at the bottom of the feed guiding area, and a fixed protrusion is provided at the top of the mounting shaft for moving the protrusions.

[0012] An inclined guide plate is installed at an angle on the bottom side of the feed pelleting chamber, located below the feed forming disc, and an outlet chute with its feed inlet end connected to the bottom of the inclined guide plate is installed at an angle on the feed pelleting chamber; a corresponding buffer pad layer is installed on the upper side of the inclined guide plate, and at least one corresponding elastic connecting rod is fixedly installed between the inclined guide plate and the feed isolation plate.

[0013] The rolling feed roller press consists of a set of two, which are symmetrically installed on the upper end of the mounting shaft. Multiple corresponding pressure roller grooves are evenly distributed on the surface of the rolling feed roller press.

[0014] The negative pressure collection assembly includes a vacuum pump and a debris collection container connected to the vacuum pump. The debris collection container is connected to the feed debris extraction pipe on the side not connected to the vacuum pump.

[0015] A filter, which is a filter bag, is installed on the feed scrap extraction pipe inside the scrap collection container.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1) The feeding device of the present invention includes a feeding channel, the discharge end of which faces the upper side of the feed pelleting chamber. A silage feeding hopper is installed on the side of the feeding channel away from the discharge end, and a dry powder material discharge hopper is provided on the side of the feeding channel closer to the discharge end. During the feeding process, the reciprocating pushing cylinder of the silage pushing component moves back and forth to squeeze and push the silage raw material under the silage feeding hopper. When the silage raw material passes the position of the dry powder material discharge hopper, the lifting drive cylinder of the cutting and mixing component drives the ultrasonic cutter to move back and forth. This effectively cuts the silage raw material again and evenly mixes the dry powder material in the dry powder material discharge hopper into the cut silage raw material during the cutting process. Thus, the dry powder material is added to the silage raw material evenly and conveniently during the feeding process, ensuring the smooth progress of the silage pelleting process.

[0017] 2) The dry powder hopper of the present invention is equipped with a corresponding buffer rubber component at the discharge port, and an ultrasonic cutter with a blade penetrating through the opening of the buffer rubber component is fixed downwards to the lifting drive cylinder. During the process of the ultrasonic cutter cutting the silage raw material downwards, the extrusion force effectively pushes the buffer rubber component to open, so as to facilitate the discharge of the dry powder; while during the process of the ultrasonic cutter moving upwards, the buffer rubber component returns to its original deformation to reduce the discharge of dry powder, thereby effectively ensuring the controllability of the dry powder addition process of the present invention.

[0018] 3) The pellet mill of this invention adds a feed forming component to the feed forming disc, which includes a feed forming tube fixed to the feed pelleting holes. The bottom of each feed forming tube is open and downward-facing, with corresponding feed pellet isolation covers, which are connected to a feed isolation plate. This creates a drainage space on the bottom side of the forming area, composed of the feed pellet isolation covers and the feed isolation plate. Feed pellet guide holes for passing through are evenly distributed on the feed pellet isolation covers. A feed pellet drainage pipe is installed within the space formed by the feed isolation plate, the feed forming disc, and the feed pellet isolation covers. In use, the feed pellet drainage pipe is connected to an external negative pressure collection component. When feed pellets are discharged after pelleting, the feed pellets generated during pelleting can be promptly collected and drained under negative pressure, ensuring the stability and palatability of the pelleted feed.

[0019] 4) The present invention further includes an ultrasonic vibrator connected to the feed isolation plate of the pellet mill, which assists in the formation of feed raw materials within the feed forming tubes through ultrasonic vibration. During the pelleting process, the ultrasonic vibrator is activated to transmit ultrasonic vibrations through the feed isolation plate and feed pellet isolation cover to each feed forming tube, thereby assisting in the compaction of feed raw materials through high-frequency vibration. Furthermore, the ultrasonic vibration keeps the material in a state of slight vibration as it passes through the feed forming tubes, which reduces frictional resistance, promotes tight pellet arrangement, and improves the surface smoothness of the feed pellets, making them less prone to breakage.

[0020] Most importantly, ultrasonic vibration can also assist in the cleaning and collection of feed fragments. This is because silage raw materials have a certain moisture content, and the feed fragments produced during pelleting naturally also have a certain moisture content. When these fragments are absorbed into the space formed by the feed separator, feed forming disc, and feed pellet isolation cover, they easily adhere to these components, thus negatively impacting their cleaning and collection. The intervention of ultrasonic vibration not only assists in the forming of feed raw materials within the feed forming tube but also prevents excessive adhesion of feed fragments to these components, ensuring smooth cleaning and collection of feed fragments.

[0021] 5) The feed pelleting chamber of the pelleting machine of the present invention is provided with a corresponding guide hopper at the top. A filter media assembly for screening feed raw materials by particle size is installed on the guide hopper. The filter media assembly includes a filter screen installed on the guide hopper. The filter screen is made of elastic metal material, and a corresponding guide area is convexly provided in the middle of the filter screen. Multiple corresponding protrusions are evenly distributed at the bottom of the guide area. A fixed protrusion is provided at the top of the mounting shaft for actuating the protrusions. As the mounting shaft rotates, the fixed protrusion rotates accordingly to actuate the protrusions, i.e., the middle of the filter screen, thereby driving the filter screen to vibrate. This allows the feed raw materials located on the upper part of the filter screen to fall more loosely, ensuring smooth feeding and screening.

[0022] 6) The pellet mill of the present invention has an inclined guide plate installed at the bottom of the feed pelleting chamber, located below the feed forming disc, and an inlet chute connected to the bottom of the inclined guide plate is installed at an inclined angle on the feed pelleting chamber. Most importantly, the present invention has a corresponding buffer pad layer installed on the upper side of the inclined guide plate, and an elastic connecting rod is fixedly installed between the inclined guide plate and the feed isolation plate. Through the intervention of the buffer pad layer, the pelleted feed particles are received and discharged without damage. Furthermore, through the intervention of the elastic connecting rod, some vibration is transmitted to the inclined guide plate, overcoming the problem of untimely discharge caused by the buffer pad layer, thereby achieving efficient and non-destructive discharge.

[0023] 7) The negative pressure collection component of the pellet mill of the present invention includes a vacuum pump and a fragment collection container connected to the vacuum pump. The side of the fragment collection container not connected to the vacuum pump is connected to a feed fragment extraction pipe, and a filter bag located inside the fragment collection container is installed on the feed fragment extraction pipe. Using the fragment collection container as an intermediary, the vacuum pump creates negative pressure in the space formed by the feed isolation plate, the feed forming disc, and the feed pellet isolation cover to extract the corresponding feed fragments into place. The extracted material enters the fragment collection container and is collected by the filter bag, thereby effectively ensuring the practical effect of the present invention.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] refer to Figure 1-10 A silage processing device includes a pelletizer for pelleting silage and a feeding device for feeding raw materials into the pelletizer. The granulator includes: The feed pelleting chamber 1 is set on the corresponding machine base 2. The feed pelleting chamber 1 is equipped with a feed forming disc 3 adapted to the pelleting of feed raw materials. The feed forming disc 3 is evenly provided with a number of feed pelleting holes for extruding feed raw materials into pellets. The feed forming assembly 4 includes a feed forming tube 401 fixed to the feed pelleting hole. The bottom of the feed forming tube 401 is open and facing downwards, and a corresponding feed pellet isolation cover 402 is provided. The feed pellet isolation cover 402 is connected to a corresponding feed isolation plate 403. Feed pellet isolation covers 402 are evenly distributed with feed pellet guide holes 5 for feed pellets to pass through. A corresponding ultrasonic vibrator 6 is connected to the feed isolation plate 403 to assist the forming of feed raw materials in the feed forming tube 401 through ultrasonic vibration. A corresponding feed pellet extraction pipe 7 is provided in the space formed by the feed isolation plate 403, the feed forming disc 3, and the feed pellet isolation cover 402. The feed pellet extraction pipe 7 is used to discharge feed pellets generated during the pelleting process. The feed roller pressing assembly 8 includes a mounting shaft 801 rotatably disposed within the feed pelleting chamber 1. The upper end of the mounting shaft 801 extends through to the upper part of the feed forming disc 3 and is horizontally rotatably mounted with at least one rolling feed roller pressing component 802 adapted for feed raw material pelleting. The mounting shaft 801 is tractively connected to the output shaft end of a corresponding drive motor 803 to drive the rolling feed roller pressing component 802 to rotate in order to extrude and pelletize the feed raw materials on the feed forming disc 3. The feeding device includes: The feeding channel 21 is supported and installed on the corresponding feeding bracket 22. The discharge end of the feeding channel 21 is directly opposite the upper side of the feed granulation chamber 1. A silage feeding hopper 23 is installed on the side of the feeding channel 21 away from the discharge end, and a dry powder feeding hopper 24 is provided on the side of the feeding channel 21 close to the discharge end. The silage pushing assembly 25 is used to push the silage raw materials in the feeding channel 21 toward its discharge end; The cutting and mixing assembly 26 is used to cut the silage material passing under the dry powder hopper 24 and mix the dry powder into the cut silage material.

[0037] The silage pushing assembly 25 includes a reciprocating pushing cylinder 2501 installed on the feeding channel 21 on the rear side of the silage feeding hopper 23. The piston rod end of the reciprocating pushing cylinder 2501 extends into the feeding channel 21 on the rear side of the silage feeding hopper 23 and is fixedly connected to a corresponding pushing plate 2502.

[0038] The dry powder hopper 24 is equipped with a corresponding buffer rubber component 27 at the discharge port. The cutting and mixing assembly 26 includes a lifting drive cylinder 2601 that can be lifted and installed on the upper side of the dry powder hopper 24. An ultrasonic cutter 2602 with a blade penetrating the opening of the buffer rubber component 27 is fixedly connected to the lifting drive cylinder 2601 facing downward.

[0039] During the feeding process, the feeding device of this invention utilizes the reciprocating pushing cylinder 2501 of the silage pushing assembly 25 to extrude and push the silage material under the silage feeding hopper 23. When the silage material passes the location of the dry powder feeding hopper 24, the lifting drive cylinder 2601 of the cutting and mixing assembly 26 drives the ultrasonic cutter 2602 to move back and forth. This effectively cuts the silage material again and evenly mixes the dry powder from the dry powder feeding hopper 24 into the cut silage material. This ensures that the dry powder is added evenly and conveniently to the silage material during feeding, guaranteeing the smooth progress of the silage pelleting process.

[0040] During the downward movement of the ultrasonic cutter 2602 to cut the silage material, the extrusion force effectively pushes the buffer rubber part 27 to open, so as to facilitate the feeding of dry powder; while during the upward movement of the ultrasonic cutter 2602, the buffer rubber part 27 restores its deformation to reduce the feeding of dry powder, thereby effectively ensuring the controllability of the dry powder addition process of the present invention.

[0041] The portion of the feed forming tube 401 not connected to the feed pelleting hole is spaced apart from the feed pelleting hole. Corresponding vibration-damping rubber tubes 9 are extruded and installed at the intervals between the feed forming tube 401 and the feed pelleting hole. During the process of driving the rolling feed roller 802 to rotate and press the material on the upper side of the feed forming disc 3 into the corresponding feed pelleting hole for pelleting, the ultrasonic vibrator 6 is activated so that each feed forming tube 401 is independently in an ultrasonic vibration state.

[0042] This invention adds a feed forming component 4 to the feed forming disc 3 of the pellet mill. This component includes a feed forming tube 401 fixed to the feed forming holes. The bottom of each feed forming tube 401 is open and downward-facing, with corresponding feed pellet isolation covers 402, which are connected to a feed isolation plate 403. This creates a drainage space on the bottom side of the forming area, composed of the feed pellet isolation covers 402 and the feed isolation plate 403. Feed pellet guide holes 5 are evenly distributed on the feed pellet isolation covers 402 for passing through feed fragments. A feed fragment extraction pipe 7 is installed within the space formed by the feed isolation plate 403, the feed forming disc 3, and the feed pellet isolation covers 402. In use, the feed fragment extraction pipe 7 is connected to an external negative pressure collection component. When feed pellets are broken during pelleting, the feed pellets generated during pelleting can be promptly cleaned and collected under negative pressure, thus ensuring the stability and palatability of the pelleted feed.

[0043] Building upon this, the present invention further connects a corresponding ultrasonic vibrator 6 to the feed isolation plate 403 of the pellet mill, thereby assisting the formation of feed raw materials within the feed forming tube 401 through ultrasonic vibration. During the pelleting process, the ultrasonic vibrator 6 is activated to transmit ultrasonic vibrations through the feed isolation plate 403 and the feed pellet isolation cover 402 to each feed forming tube 401, thereby assisting in compacting the feed raw materials through high-frequency vibration. Furthermore, the ultrasonic vibration keeps the material in a state of slight vibration as it passes through the feed forming tube 401, which reduces frictional resistance, promotes tight pellet arrangement, and improves the surface smoothness of the feed pellets, making them less prone to breakage.

[0044] Most importantly, ultrasonic vibration can also assist in the cleaning and collection of feed fragments. This is because silage raw materials have a certain moisture content, and the feed fragments produced during pelleting naturally also have a certain moisture content. When these fragments are adsorbed into the space formed by the feed isolation plate 403, the feed forming disc 3, and the feed pellet isolation cover 402, they easily adhere to these components, thus negatively impacting their cleaning and collection. The intervention of ultrasonic vibration not only assists in the forming of feed raw materials within the feed forming tube 401 but also prevents excessive adhesion of feed fragments to the feed isolation plate 403, the feed forming disc 3, or the feed pellet isolation cover 402, ensuring smooth cleaning and collection of feed fragments.

[0045] A corresponding transverse cutting component 10 is fixedly installed on the mounting shaft 801 on the lower side of the feed isolation plate 403. The feed fragment extraction pipe 7 is connected to the feed end of the corresponding negative pressure collection component 11. When the transverse cutting component 10 cuts the formed material with the rotation of the mounting shaft 801, the negative pressure collection component 11 starts to draw negative pressure into the space formed by the feed isolation plate 403, the feed forming disc 3, and the feed pellet isolation cover 402, so as to collect the fragments caused by cutting under negative pressure. During the negative pressure collection of fragments, the inner surfaces of the feed isolation plate 403, the feed forming disc 3, and the feed pellet isolation cover 402 are respectively under the drive of the ultrasonic vibrator 6 in an ultrasonic vibration state.

[0046] The upper part of the feed pelleting chamber 1 is provided with a corresponding feed guide hopper 12, and a filter media assembly 13 for screening feed raw materials is installed on the feed guide hopper 12. The filter media assembly 13 includes a filter screen 1301 installed on the feed guide hopper 12. The filter screen 1301 is made of elastic metal material, and a corresponding feed guiding area 14 is convexly provided in the middle of the filter screen 1301. A plurality of corresponding protrusions 1302 are evenly distributed at the bottom of the feed guiding area 14. A fixed protrusion 1303 for moving the protrusions 1302 is provided at the top of the mounting shaft 801.

[0047] During the granulation process, as the mounting shaft 801 rotates, the fixed convex edge 1303 rotates accordingly to move the convex block 1302, that is, the middle part of the filter screen 1301, thereby driving the filter screen 1301 to shake, so that the feed raw materials located on the upper side of the filter screen 1301 can fall more loosely, so as to ensure the smooth feeding and screening process.

[0048] An inclined guide plate 15 is installed at an angle on the bottom side of the feed pelleting chamber 1, located below the feed forming disc 3. An outlet trough 16 with its feed inlet end connected to the bottom of the inclined guide plate 15 is installed at an angle on the feed pelleting chamber 1. A corresponding buffer pad layer 17 is installed on the upper side of the inclined guide plate 15, and at least one corresponding elastic connecting rod 18 is fixedly installed between the inclined guide plate 15 and the feed isolation plate 403.

[0049] The buffer pad layer 17 is used to receive and discharge the granulated feed pellets in a non-destructive manner. The elastic connecting rod 18 is used to transmit some of the vibration to the inclined guide plate 15, so as to overcome the problem of untimely discharge caused by the buffer pad layer 17, and thus achieve efficient and non-destructive discharge.

[0050] The rolling feed roller press 802 is a set of two, which are symmetrically installed on the upper end of the mounting shaft 801. Multiple corresponding press roller grooves 19 are evenly distributed on the surface of the rolling feed roller press 802.

[0051] The negative pressure collection assembly 11 includes a vacuum pump 1101 and a fragment collection container 1102 connected to the vacuum pump 1101. The fragment collection container 1102 is connected to the feed fragment extraction pipe 7 on the side not connected to the vacuum pump 1101.

[0052] A filter 20 is installed on the feed scrap extraction pipe 7, located inside the scrap collection container 1102. The filter 20 is a filter bag.

[0053] The pellet mill of the present invention uses the material collection container 1102 as a transfer point. The vacuum pump 1101 applies negative pressure to the space formed by the feed isolation plate 403, the feed forming plate 3, and the feed pellet isolation cover 402 to extract the corresponding feed fragments into place. The extracted material enters the material collection container 1102 and is collected by the filter bag, thereby effectively ensuring the practical effect of the present invention.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
