Description

Technical Field

[0001] This invention relates to the field of feed processing technology, specifically a concentrated feed production process. Background Technology

[0002] Feed is a general term for the food of animals raised by all people. In order to make it easier to feed animals, feed ingredients are usually crushed and ground to reduce the overall volume of the feed ingredients and make it easier for animals to eat. Therefore, a feed fine grinding device is needed to facilitate feed processing.

[0003] According to a Chinese patent application with publication number 202410896907.4, a fine grinding device for feed processing is disclosed. By opening the discharge trough inside the intermediate frame, it is convenient to transport the ground feed through the inclined surface and facilitate the discharge of the feed through the bottom drain. At the same time, the inclined surface helps to buffer the feed during the flow process to avoid excessive discharge force, which is convenient for use. However, the above-mentioned fine grinding device for feed processing still has the problem of not being convenient to adjust the coarseness of the feed. The feed particle size is uniform and the product variety is not strong. To this end, we propose a concentrated feed production process to solve the above-mentioned technical problems.

[0043] As a preferred embodiment of the present invention, the lower part of the outer wall of the outer frame is provided with three discharge ports distributed at equal angles. A corrugated telescopic sleeve is fixedly installed between the bottom of the forming sleeve and the inner bottom side of the outer frame. The corrugated telescopic sleeve is located around a plurality of guide rods. A conical guide platform is fixedly installed on the inner bottom side of the outer frame. The conical guide platform is located around the corrugated telescopic sleeve and inside the three discharge ports.

[0044] As a preferred embodiment of the present invention, three position sensors are fixedly installed on the outer wall of the outer frame, and the three position sensors are used to sense the height position of the molded sleeve.

[0045] A production method for concentrated feed includes the following steps:

[0046] S1, adjust the height of the forming sleeve according to the coarseness of the feed to be processed, and adjust the fine hole, medium hole or coarse hole to the periphery of the three grinding discs as needed;

[0047] S2, the conveying unit conveys the raw material into the forming sleeve;

[0048] S3 uses a motor to rotate three grinding discs, crushing the raw materials inside the forming sleeve.

[0049] Compared with the prior art, the beneficial effects of the present invention are:

[0050] 1. In this invention, the hollow lead screw is rotated by turning the handwheel, causing the adjusting nut to move upward or downward along the axial direction of the hollow lead screw, which in turn causes the forming sleeve to move upward or downward. During the upward or downward movement of the forming sleeve, multiple fine holes, medium holes and coarse holes will move together, thereby adjusting the fine holes, medium holes or coarse holes to the periphery of the three grinding discs according to the coarseness of the feed to be processed, for processing feed of different coarseness.

[0051] 2. In this invention, the output shaft of the power motor drives the central vertical shaft to rotate. The rotation of the central vertical shaft drives the three overlapping rods to rotate together through the rolling frame. The rotation of the overlapping rods drives the torsion disc to rotate together. The rotation of the torsion disc drives the plum blossom groove to rotate together. Furthermore, through the contact between the inner wall of the plum blossom groove and the outer wall of the ball head, the ball head and the insertion rod rotate together. The rotation of the insertion rod then drives the spiral conveyor plate to rotate along the inside of the conveying sleeve, conveying the raw material downward to the inside of the forming sleeve.

[0052] 3. In this invention, when the raw material inside the molding sleeve is compressed, the resistance of the spiral conveyor blade increases. When the resistance of the spiral conveyor blade is greater than the elastic force of the elastic rod, even though the torsion disc continues to rotate, the outer wall of the ball head slides along the side wall of the plum blossom groove, the inner wall and bottom wall of the plum blossom groove, and the top of the protrusion, thereby causing the elastic rod to undergo elastic bending deformation. At this time, the insertion rod does not rotate, that is, the spiral conveyor blade stops conveying the raw material downward, thereby alleviating the problem of raw material compression inside the molding sleeve.

[0053] 4. In this invention, after all the raw materials inside the funnel have been conveyed, the electric steel is started. The output rod of the electric steel drives the U-shaped frame and key sleeve to move upward, so that the bottom of the key sleeve releases its contact with the bottom of the stepped groove and then slides to the outer periphery of the key block. At this time, due to the locking effect of the key sleeve and the key block, the insertion rod cannot rotate. At this time, the torsion disk continues to rotate, which causes the ball head to slide along the inner wall of the plum blossom groove. During this period, the ball head also slides along the bottom wall of the plum blossom groove and the top of the protrusion. Therefore, the ball head will drive the insertion rod to move up and down reciprocally through the elastic rod, thereby causing the spiral conveyor plate to vibrate up and down. This vibrates the residual raw materials remaining on the inner wall of the conveyor sleeve and the surface of the spiral conveyor plate downward. Under the vibration, the raw materials fall into the inside of the forming sleeve and are crushed by the grinding disc to avoid waste of raw materials. Attached Figure Description

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] Please see Figures 1-10 The technical solution provided by the present invention specifically includes the following embodiments:

[0067] A concentrated feed production process includes a crushing unit 100 and a conveying unit 200. The crushing unit 100 is used for crushing and adjusting the coarseness of the feed, and the conveying unit 200 is fixedly installed on top of the crushing unit 100 for feeding and stopping the feed raw materials.

[0068] For further details, please refer to [link / reference]. Figures 3-7 As shown:

[0069] The compaction unit 100 includes an outer frame 101, guide rods 102, forming sleeve 103, fine holes 104, medium holes 105, coarse holes 106, linear bearings 107, a tray 108, a central vertical shaft 109, a compaction frame 1010, a fixed shaft 1011, a compaction disc 1012, an adjusting nut 1013, a hollow lead screw 1014, a handwheel 1015, a power motor 1016, a hanging rod 1017, a motor fixing plate 1018, and support feet 1019. Four guide rods 102 are fixedly installed on the bottom inner side of the outer frame 101, arranged in a circumferential array. The forming sleeve 103 slides... The forming sleeve 103 is movably installed around the four guide rods 102. Multiple fine holes 104, medium holes 105, and coarse holes 106 for processing fine feed, are opened on its surface. A linear bearing 107 is fixedly installed at the bottom of the forming sleeve 103 and slidably installed on the outer wall of the guide rods 102. A tray 108 is fixedly installed on the top of the four guide rods 102, and its outer wall is slidably connected to the inner wall of the forming sleeve 103. A central vertical shaft 109 is rotatably installed inside the outer frame 101 and penetrates both the outer frame 101 and the tray 108. A rolling frame 1010 is fixedly installed on the top of the central vertical shaft 109. Fixed shafts 1011 are uniformly distributed and fixedly installed at the bottom of the rolling frame 1010. The rolling disc 1012 is rotatably installed around the fixed shafts 1011, with its outer wall in contact with the inner wall of the forming sleeve 103. Adjusting nut 1013 is fixedly installed in the middle of the inner side of the bottom of the forming sleeve 103. Hollow lead screw 1014 is threaded into the adjusting nut 1013 and movably passes through the forming sleeve 103 and the outer frame 101, and is rotatably connected to the outer frame 101 via bearings. Hollow lead screw 1014 is located around the central vertical shaft 109. Handwheel 1015 is fixedly installed on the lower part of the outer wall of hollow lead screw 1014. A power motor is also present. The top of the output shaft 1016 is fixedly connected to the bottom of the central vertical shaft 109 via a coupling. The lifting rods 1017 are fixedly installed at equal angles at the bottom of the outer frame 101 and are located around the handwheel 1015. The motor fixing plate 1018 is fixedly installed at the bottom of the multiple lifting rods 1017. The power motor 1016 is fixedly installed at the bottom of the motor fixing plate 1018. The support legs 1019 are fixedly installed at equal angles at the bottom of the outer frame 101 and are located around the power motor 1016. Three position sensors 400 are fixedly installed on the outer wall of the outer frame 101. The three position sensors 400 are used to sense the height position of the forming sleeve 103.

[0070] Specifically, rotating the handwheel 1015 drives the hollow lead screw 1014 to rotate. Since the hollow lead screw 1014 is threadedly connected to the adjusting nut 1013, the rotation of the hollow lead screw 1014 causes the adjusting nut 1013 to move upward or downward along the axial direction of the hollow lead screw 1014, thereby causing the forming sleeve 103 to move upward or downward. The forming sleeve 103 is guided by the four guide rods 102, making its upward or downward movement smoother and more stable. During the upward or downward movement of the forming sleeve 103, multiple fine holes 104, medium holes 105, and coarse holes 106 move together. Thus, depending on the coarseness of the processed feed, the fine holes 104, medium holes 105, or coarse holes 106 are adjusted to the periphery of the three grinding discs 1012. Among them, the outer frame 10 Three position sensors 400 on the outer wall are used to detect the height of the forming sleeve 103, so that people can know whether the fine hole 104, medium hole 105 or coarse hole 106 has reached the required height. The output shaft of the power motor 1016 drives the central vertical shaft 109 to rotate. The rotation of the central vertical shaft 109 drives the three fixed shafts 1011 and the three grinding discs 1012 to rotate inside the forming sleeve 103 through the rolling frame 1010, and drives the conveying unit 200 to operate, conveying the raw material into the forming sleeve 103. The raw material is crushed by the rotating grinding discs 1012. The crushed raw material is squeezed into a cylindrical shape from the inside of the fine hole 104, medium hole 105 or coarse hole 106, and squeezed outward along the inside of the fine hole 104, medium hole 105 or coarse hole 106.

[0071] For further details, please refer to [link / reference]. Figure 8 and Figure 9 As shown:

[0072] The conveying unit 200 includes overlapping rods 201, a torsion disc 202, a plum blossom groove 203, a plug-in hole 204, a plug-in rod 205, an elastic rod 206, a ball head 207, a spiral conveyor plate 209, and a conveying sleeve 2015. The overlapping rods 201 are evenly distributed and fixedly installed on the top of the compaction frame 1010. The torsion disc 202 is fixedly installed on the top of multiple overlapping rods 201. The plum blossom groove 203 is opened on the top of the torsion disc 202. The plug-in hole 204 is opened through the middle of the bottom of the plum blossom groove 203. The plug-in rod 205... 05 is slidably installed inside the insertion hole 204. The elastic rods 206 are fixedly installed on the outer wall of the insertion rod 205 at equal angles. Ball heads 207 are fixedly installed at the ends of the elastic rods 206. The ball heads 207 are slidably located inside the plum blossom groove 203. The spiral conveying plate 209 is fixedly installed on the outer wall of the insertion rod 205. The conveying sleeve 2015 is sleeved on the periphery of the spiral conveying plate 209, and passes through the top of the outer frame 101 and extends into it. The outer wall of the conveying sleeve 2015 is fixedly connected to the through hole of the outer frame 101.

[0073] Specifically, the output shaft of the power motor 1016 drives the central vertical shaft 109 to rotate. The rotation of the central vertical shaft 109, through the rolling frame 1010, drives the three overlapping rods 201 to rotate together. The rotation of the overlapping rods 201 drives the torsion disc 202 to rotate together. The rotation of the torsion disc 202 drives the plum blossom groove 203 to rotate together. Furthermore, through the contact between the inner wall of the plum blossom groove 203 and the outer wall of the ball head 207, the ball head 207, along with the insertion rod 205, rotates together. The rotation of the insertion rod 205 then drives the spiral conveyor plate 209 to rotate along the inside of the conveying sleeve 2015, conveying the raw material downwards into the forming sleeve 103. It should be noted that when the raw material accumulates inside the forming sleeve 103, the resistance to the rotation of the spiral conveyor plate 209 increases. When the resistance is greater than the elastic force of the elastic rod 206, although the torsion disk 202 continues to rotate, the outer wall of the ball head 207 slides along the side wall of the plum blossom groove 203, the inner wall and bottom wall of the plum blossom groove 203, and the top of the protrusion 208, causing the elastic rod 206 to undergo elastic bending deformation. At this time, the insertion rod 205 does not rotate, that is, the spiral conveyor plate 209 stops conveying raw materials downward, thereby alleviating the problem of raw material accumulation inside the forming sleeve 103. When the accumulation inside the forming sleeve 103 is relieved, the rotational resistance of the spiral conveyor plate 209 decreases. At this time, the torsion disk 202 rotates, and the ball head 207 continues to rotate through the plum blossom groove 203. On the same principle, the insertion rod 205 continues to drive the spiral conveyor plate 209 to rotate, and continues to convey raw materials into the forming sleeve 103.

[0074] For further details, please refer to [link / reference]. Figure 9 and Figure 10 As shown:

[0075] The conveying unit 200 also includes a protrusion 208, a stepped groove 2010, a key block 2011, a power steel 2012, a U-shaped frame 2013, and a key sleeve 2014. The protrusion 208 is fixedly installed at the bottom of the plum blossom groove 203 at equal angles. The stepped groove 2010 is opened on the upper part of the outer wall of the plug-in rod 205. The key block 2011 is opened on the upper part of the outer wall of the stepped groove 2010. The power steel 2012 is fixedly installed on the top of the plug-in rod 205. The U-shaped frame 2013 is fixedly installed on the bottom of the output rod of the power steel 2012. The key sleeve 2014 is fixedly installed on the bottom of the U-shaped frame 2013. The key sleeve 2014 is compatible with the specifications of the power steel 2012. The key sleeve 2014 is fitted around the stepped groove 2010, and its bottom abuts against the bottom of the stepped groove 2010.

[0076] Specifically, after all the raw materials inside the funnel 302 have been conveyed, the electric steel 2012 is started. The output rod of the electric steel 2012 drives the U-shaped frame 2013 and key sleeve 2014 upwards, causing the bottom of the key sleeve 2014 to release its contact with the bottom of the stepped groove 2010. It then slides to the outer periphery of the key block 2011. At this point, due to the locking effect of the key sleeve 2014 and the key block 2011, the insertion rod 205 cannot rotate. Meanwhile, the torsion disc 202 continues to rotate, causing the ball head 207 to move along... The inner wall of the plum blossom groove 203 slides, and during this time, the ball head 207 also slides along the bottom wall of the plum blossom groove 203 and the top of the protrusion 208. Therefore, the ball head 207 will drive the plug rod 205 to move up and down through the elastic rod 206, thereby causing the spiral conveyor plate 209 to vibrate up and down, and shake the residual material remaining on the inner wall of the conveyor sleeve 2015 and the surface of the spiral conveyor plate 209 downward. Under the action of vibration, the material falls into the inside of the forming sleeve 103 and is crushed by the grinding plate 1012 to avoid material waste.

[0077] For further details, please refer to [link / reference]. Figure 3 As shown:

[0078] Three equally angled support rods 301 are fixedly installed on the top of the outer frame 101. A funnel 302 is fixedly installed on the top of the three support rods 301. The output end of the funnel 302 is connected to the input end of the conveying sleeve 2015 through a flange. A fixing plate 303 is fixedly installed on the outer wall of the three support rods 301. A power steel 2012 is fixedly installed on the top of the fixing plate 303, and the output rod of the power steel 2012 moves through the interior of the fixing plate 303.

[0079] Specifically, by feeding raw materials for producing feed into the funnel 302, the raw materials flow from the output end of the funnel 302 to the input end of the conveying sleeve 2015 and then into the conveying sleeve 2015.

[0080] For further details, please refer to [link / reference]. Figure 1 and Figure 2 As shown:

[0081] The lower part of the outer wall of the outer frame 101 has three discharge ports 1001 distributed at equal angles. A corrugated telescopic sleeve 500 is fixedly installed between the bottom of the forming sleeve 103 and the inner bottom side of the outer frame 101. The corrugated telescopic sleeve 500 is located around the multiple guide rods 102. A conical guide platform 600 is fixedly installed on the inner bottom side of the outer frame 101. The conical guide platform 600 is located around the corrugated telescopic sleeve 500 and inside the three discharge ports 1001.

[0082] Specifically, the material is conveyed into the forming sleeve 103 and crushed by the rotating grinding disc 1012. The extruded material is squeezed into a cylindrical shape from the inside of the fine hole 104, medium hole 105 or coarse hole 106, and squeezed outward along the inside of the fine hole 104, medium hole 105 or coarse hole 106. Finally, it is discharged from the forming sleeve 103, falls on the conical surface of the conical guide table 600, and slides out from the inside of the discharge port 1001 along the conical surface of the conical guide table 600.

[0083] A production method for concentrated feed includes the following steps:

[0084] S1, adjust the height of the forming sleeve 103 according to the coarseness of the feed to be processed, and adjust the fine hole 104, medium hole 105 or coarse hole 106 to the periphery of the three grinding discs 1012 as needed.

[0085] S2, the conveying unit 200 conveys the raw material into the forming sleeve 103;

[0086] S3, through the action of the power motor 1016, rotates the three grinding discs 1012 to crush the raw material inside the forming sleeve 103.

[0087] In this concentrated feed production process, the coarseness of the feed is first adjusted during operation. Specifically, the hollow screw 1014 is rotated by turning the handwheel 1015. Since the hollow screw 1014 is threadedly connected to the adjusting nut 1013, the rotation of the hollow screw 1014 causes the adjusting nut 1013 to move upward or downward along the axial direction of the hollow screw 1014. This, in turn, causes the forming sleeve 103 to move upward or downward. The forming sleeve 103 is guided by four guide rods 102, making its upward or downward movement smoother and more stable. During the upward or downward movement of the forming sleeve 103, multiple fine holes 104, medium holes 105, and coarse holes 106 move together. Thus, depending on the coarseness of the processed feed, the fine holes 104, medium holes 105, or coarse holes 106 are adjusted to the periphery of the three grinding discs 1012.

[0088] Next, the raw materials for feed production are fed into the funnel 302, flowing from the output end of the funnel 302 to the input end of the conveying sleeve 2015, and then into the conveying sleeve 2015. During this process, the output shaft of the power motor 1016 drives the central vertical shaft 109 to rotate. The rotation of the central vertical shaft 109 drives the three fixed shafts 1011 and the three grinding discs 1012 to rotate inside the forming sleeve 103 via the rolling frame 1010. At the same time, the rolling frame 1010 also drives the torsion disc 202 to rotate together through the connection of the three overlapping rods 201. The rotation of the torsion disc 202 drives the plum blossom trough 203 to rotate together, further passing through the plum blossom trough 203. The contact between the wall and the outer wall of the ball head 207 causes the ball head 207 and the plug rod 205 to rotate together. The rotation of the plug rod 205 then drives the spiral conveyor plate 209 to rotate along the inside of the conveyor sleeve 2015, conveying the raw material downward to the inside of the forming sleeve 103. It is crushed by the rotating grinding disc 1012. The extruded raw material is squeezed into a cylindrical shape from the inside of the fine hole 104, the medium hole 105 or the coarse hole 106, and squeezed outward along the inside of the fine hole 104, the medium hole 105 or the coarse hole 106. Finally, it is discharged from the forming sleeve 103, falls on the conical surface of the conical guide platform 600, and slides out from the inside of the discharge port 1001 along the conical surface of the conical guide platform 600.

[0089] It should be noted that when the material inside the forming sleeve 103 is accumulating, the resistance to the rotation of the spiral conveyor 209 increases. When the resistance of the spiral conveyor 209 is greater than the elastic force of the elastic rod 206, although the torsion disk 202 continues to rotate, the outer wall of the ball head 207 slides along the inner wall of the plum blossom groove 203, causing the elastic rod 206 to undergo elastic bending deformation. At this time, the insertion rod 205 does not rotate, that is, the spiral conveyor 209 stops conveying material downwards, thereby alleviating the problem of material accumulation inside the forming sleeve 103. When the accumulation inside the forming sleeve 103 is relieved, the rotation resistance of the spiral conveyor 209 decreases. At this time, the torsion disk 202 rotates, and the ball head 207 continues to rotate through the plum blossom groove 203. On the same principle, the insertion rod 205 continues to drive the spiral conveyor 209 to rotate, continuing to convey material into the forming sleeve 103.

[0090] After all the raw materials inside the funnel 302 have been conveyed, the electric steel 2012 is started. The output rod of the electric steel 2012 drives the U-shaped frame 2013 and the key sleeve 2014 upward to move, causing the bottom of the key sleeve 2014 to release its contact with the bottom of the stepped groove 2010, and then slide to the outer periphery of the key block 2011. At this time, due to the locking effect of the key sleeve 2014 and the key block 2011, the insertion rod 205 cannot rotate. At this time, the torsion disk 202 continues to rotate, causing the ball head 207 to follow the cloverleaf pattern. The inner wall of the groove 203 slides, and during this time, the ball head 207 also slides along the bottom wall of the plum blossom groove 203 and the top of the protrusion 208. Therefore, the ball head 207 will drive the plug rod 205 to move up and down repeatedly through the elastic rod 206, thereby causing the spiral conveyor plate 209 to vibrate up and down, and shake the residual material remaining on the inner wall of the conveyor sleeve 2015 and the surface of the spiral conveyor plate 209 downward. Under the action of vibration, the material falls into the interior of the forming sleeve 103 and is crushed by the grinding plate 1012 to avoid material waste.

[0091] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
