Description

Technical Field

[0001] This invention relates to the field of centrifuge facilities, and more particularly to a raw material pretreatment device for silage processing. Background Technology

[0002] Silage is a type of feed made from plant-based feed with high moisture content through sealing and fermentation. It is mainly used to feed ruminants. During the processing of silage, centrifugal screening equipment is often used to screen the crushed raw materials in order to select qualified products. However, in the existing centrifugal screening equipment, the centrifugal force generated by the rotation of the centrifugal screen cylinder causes the raw materials to always adhere to the inner wall of the centrifugal screen cylinder, which prevents the raw materials from moving fully in the centrifugal screen cylinder and seriously affects the screening effect. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a raw material pretreatment device for silage processing.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a raw material pretreatment device for silage processing, comprising a bucket base, a movable platform slidably disposed above the bucket base, a cylindrical shell rotatably mounted through the upper end of the movable platform, a centrifugal sieve cylinder coaxially fixedly mounted inside the cylindrical shell, a gap being left between the centrifugal sieve cylinder and the cylindrical shell, a feeding component installed on one side of the upper end of the bucket base, the feeding component communicating with the centrifugal sieve cylinder, and a first servo motor installed on the other side of the upper end of the bucket base, with a pusher connecting the output end of the first servo motor to the side of the movable platform.

[0005] Preferably, slides are symmetrically fixedly installed at the front and rear edges of the lower end of the mobile platform, and two bearing rods are symmetrically installed at the upper end of the bucket. The slides are attached to the outer surface of the bearing rods, and L-shaped frames are fixedly installed on the front and rear ends of the first servo motor. The ends of the L-shaped frames are fixed to the bucket.

[0006] Preferably, a bearing shaft is coaxially arranged below the output end of the first servo motor. The bearing shaft is rotatably mounted on the bucket seat. A top frame is fixedly mounted on both the end of the bearing shaft and the output end of the first servo motor. A connecting shaft is rotatably mounted through the ends of the two top frames. One end of the push frame is embedded in the connecting shaft. A slot seat is fixedly mounted in the middle of the side of the moving platform. The other end of the push frame is rotatably mounted inside the slot seat.

[0007] Preferably, a rod seat is fixedly installed at the end of the bearing rod, and the lower end of the rod seat is fixed to the bucket seat. A second servo motor is arranged on the front side of the cylinder shell. A motor frame is fixedly installed at the rear end of the second servo motor. The end of the motor frame is fixed to the moving platform. A pulley is coaxially embedded between the output end of the second servo motor and the lower part of the outer surface of the cylinder shell. A synchronous belt is connected between the two pulleys.

[0008] Preferably, a solenoid valve is installed on the discharge pipe of the centrifugal screen cylinder, a pipe frame is fixedly installed at the lower middle part of the moving platform, an inclined guide is fixedly installed at the end of the pipe frame, the opening of the discharge pipe of the centrifugal screen cylinder is located inside the opening of the inclined guide, and the inclination direction of the inclined guide is opposite to the inclination direction of the inner bottom surface of the bucket.

[0009] Preferably, the feeding component includes a vertical frame fixedly installed on one side of the upper end of the hopper base, a hopper fixedly installed at the end of the vertical frame, a second solenoid valve installed on the discharge pipe of the hopper, a fixing frame fixedly installed at the rear end of the vertical frame, a disc fixedly installed at the end of the fixing frame, the discharge pipe of the hopper being fixedly connected to the upper edge of the disc, a flexible hose being fixedly connected to the lower edge of the disc, the lower end of the flexible hose being connected to the centrifugal sieve cylinder, and the flexible hose being rotatably connected to the centrifugal sieve cylinder.

[0010] Preferably, the upper end of the hose is aligned with the discharge pipe opening of the hopper, and a first reinforcing frame is fixedly installed at both the front and rear ends of the upright frame. The end of the first reinforcing frame is fixed to the hopper base, and a second reinforcing frame is fixedly installed at the upper end of the upright frame. The end of the second reinforcing frame is fixed to the hopper. A drive shaft is rotatably installed between the upper and lower end faces of the disc body. A material blocking disc is coaxially embedded in the middle of the outer surface of the drive shaft. The material blocking disc fits into the interior of the disc body, and two discharge holes are symmetrically opened through the upper end face of the material blocking disc.

[0011] Preferably, a transmission column is rotatably mounted on the outer surface of the disc body. A second pulley is coaxially embedded at the upper end of the transmission column and the upper end of the transmission shaft. A second synchronous belt connects the two second pulleys. A gear is coaxially embedded at the lower end of the transmission column. A toothed plate meshes with the outer side of the gear. A connecting frame is fixedly mounted at the rear end of the toothed plate. The end of the connecting frame is fixed to the moving platform.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the No. 2 servo motor is working and driving the centrifugal screen cylinder to rotate to centrifuge and screen the raw materials inside the centrifugal screen cylinder, the No. 1 servo motor will work synchronously to drive the top frame to rotate, which in turn drives the push frame to move, so that the moving table can swing back and forth on the support rod, which in turn drives the rotating centrifugal screen cylinder to swing back and forth, so that the raw materials can move fully in the centrifugal screen cylinder, so as to avoid the raw materials always adhering to the inner wall of the centrifugal screen cylinder under the action of centrifugal force, thereby improving the centrifugal screening effect.

[0014] 2. When the moving table drives the centrifugal screen cylinder to swing back and forth, it will also drive the toothed plate to move left and right simultaneously, thereby driving the gear meshing with the toothed plate to rotate. This allows the transmission column to drive the material blocking disc on the transmission shaft to rotate in the disc body via the No. 2 synchronous belt. When the material in the hopper is connected to the discharge hole and the material outlet of the hopper, it is fed into the centrifugal screen cylinder. When they are misaligned, the material is prevented from being fed into the centrifugal screen cylinder. This allows the material to be added to the centrifugal screen cylinder intermittently in small amounts, so as to avoid the accumulation of too much material in the centrifugal screen cylinder and affect the screening. This ensures the normal operation of the screening.

[0015] 3. The screened raw material will fall into the hopper through the gap between the centrifugal screen cylinder and the shell and be discharged. At the same time, the No. 2 solenoid valve on the hopper can be closed to stop feeding, and the No. 1 solenoid valve on the centrifugal screen cylinder can be opened to allow the screened raw material in the centrifugal screen cylinder to fall into the inclined guide tube and be guided out. The feeding process is simple and convenient to use. Attached Figure Description

[0023] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] like Figures 1-6 The illustrated raw material pretreatment device for silage processing includes a hopper 1. A movable platform 14 is slidably mounted above the hopper 1, supporting a cylindrical shell 13. The cylindrical shell 13 is rotatably mounted through the upper end of the movable platform 14. A centrifugal sieve cylinder 12 is coaxially fixed inside the cylindrical shell 13, with a gap between the centrifugal sieve cylinder 12 and the cylindrical shell 13 for discharging the screened raw materials. A feeding component is installed on one side of the upper end of the hopper 1, communicating with the centrifugal sieve cylinder 12. A feeding component is installed on the other side of the upper end of the hopper 1. The system is equipped with a No. 1 servo motor 15, which drives the pusher 25 to move and push or pull the moving table 14. The pusher 25 is connected between the output end of the No. 1 servo motor 15 and the side of the moving table 14. The No. 1 servo motor 15 will work synchronously to drive the top frame 26 to rotate, which in turn drives the pusher 25 to move, so that the moving table 14 can swing back and forth on the support rod 23, which in turn drives the rotating centrifugal screen cylinder 12 to swing back and forth, so that the raw material can move fully in the centrifugal screen cylinder 12 for centrifugal screening.

[0025] Slides 5 are symmetrically fixedly installed at the front and rear edges of the lower end of the moving platform 14. Two bearing rods 23 are symmetrically installed at the upper end of the bucket 1. The slides 5 and the bearing rods 23 serve to guide the moving platform 14. The slides 5 are attached to the outer surface of the bearing rods 23. L-shaped frames 29 are fixedly installed on the front and rear ends of the first servo motor 15. The L-shaped frames 29 serve to fix the first servo motor 15. The ends of the L-shaped frames 29 are fixed to the bucket 1.

[0026] A bearing shaft 27 is coaxially arranged below the output end of the first servo motor 15. The bearing shaft 27 is rotatably mounted on the bucket seat 1. The bearing shaft 27 serves to support the top frame 26. The top frame 26 is fixedly mounted on both the end of the bearing shaft 27 and the output end of the first servo motor 15. The top frame 26 drives the push frame 25 to move. A connecting shaft 28 is rotatably mounted between the ends of the two top frames 26. The connecting shaft 28 serves to connect the top frame 26 and the push frame 25 together. One end of the push frame 25 is embedded in the connecting shaft 28. A slot seat 24 is fixedly mounted in the middle of the side of the moving table 14. The slot seat 24 serves to facilitate connection. The other end of the push frame 25 is rotatably mounted inside the slot seat 24.

[0027] A rod seat 35 is fixedly installed at the end of the supporting rod 23. The lower end of the rod seat 35 is fixed to the bucket seat 1. The rod seat 35 serves to fix the supporting rod 23. A second servo motor 18 is arranged on the front side of the cylinder shell 13. A motor frame 17 is fixedly installed at the rear end of the second servo motor 18. The motor frame 17 serves to fix the second servo motor 18. The end of the motor frame 17 is fixed to the moving platform 14. The second servo motor 18 drives the cylinder shell 13 to rotate via the first synchronous belt 22. The output end of the second servo motor 18 and the lower part of the outer surface of the cylinder shell 13 are coaxially embedded with a first pulley 6. The first pulley 6 serves to connect to the first synchronous belt 22. The first synchronous belt 22 is connected between the two first pulleys 6. The first synchronous belt 22 serves to transmit power. The second servo motor 18 drives the cylinder shell 13 to rotate via the first synchronous belt 22, which in turn drives the centrifugal screen cylinder 12 inside the cylinder shell 13 to rotate, so as to centrifuge and screen the raw materials inside the centrifugal screen cylinder 12.

[0028] A solenoid valve 4 is installed on the discharge pipe of the centrifugal sieve cylinder 12. The solenoid valve 4 is used to open and close the discharge pipe of the centrifugal sieve cylinder 12. A pipe frame 21 is fixedly installed in the middle of the lower end of the moving platform 14. An inclined guide tube 20 is fixedly installed at the end of the pipe frame 21. The pipe frame 21 is used to fix the inclined guide tube 20. The outlet of the discharge pipe of the centrifugal sieve cylinder 12 is located inside the outlet of the inclined guide tube 20. The inclined guide tube 20 is used to guide the raw material. The inclination direction of the inclined guide tube 20 is opposite to the inclination direction of the inner bottom surface of the hopper 1, which can prevent the screened raw materials from mixing together during the discharge process.

[0029] The feeding component includes a vertical frame 3 fixedly installed on one side of the upper end of the hopper 1. A hopper 7 is fixedly installed at the end of the vertical frame 3, which serves to fix the hopper 7. A second solenoid valve 30 is installed on the discharge pipe of the hopper 7. The second solenoid valve 30 is used to open and close the discharge pipe of the hopper 7. Both the second solenoid valve 30 and the first solenoid valve 4 are controlled by remote control technology. Since remote control is existing technology, it is not described in detail here. A fixing frame 9 is fixedly installed at the rear end of the vertical frame 3. A disc body 10 is fixedly installed at the end of the fixing frame 9, which serves to fix the disc body 10. The discharge pipe of the hopper 7 is fixedly connected to the upper edge of the disc body 10. A flexible hose 11 is fixedly connected to the lower edge of the disc body 10. The lower end of the flexible hose 11 is connected to the centrifugal screen cylinder 12, and the flexible hose 11 is rotatably connected to the centrifugal screen cylinder 12 to avoid the centrifugal screen cylinder 12 being affected by the flexible hose 11 when it rotates for centrifugal screening.

[0030] The upper end of the hose 11 is aligned with the discharge pipe opening of the hopper 7 to facilitate the falling of raw materials. The front and rear ends of the upright frame 3 are fixedly installed with a first reinforcing frame 2. The end of the first reinforcing frame 2 is fixed to the hopper base 1. The upper end of the upright frame 3 is fixedly installed with a second reinforcing frame 8. The end of the second reinforcing frame 8 is fixed to the hopper 7. Both the first reinforcing frame 2 and the second reinforcing frame 8 serve to improve the connection strength. A drive shaft 31 is rotatably installed between the upper and lower end faces of the disc body 10. A material blocking disc 37 is coaxially embedded in the middle of the outer surface of the drive shaft 31. The drive shaft 31 drives the material blocking disc 37 to rotate. The material blocking disc 37 fits into the inside of the disc body 10 and prevents the raw materials from passing through. Two discharge holes 36 are symmetrically opened through the upper end face of the material blocking disc 37. The discharge holes 36 allow the raw materials to pass through.

[0031] A transmission column 32 is rotatably mounted on the outer surface of the disc body 10. The upper end of the transmission column 32 and the upper end of the transmission shaft 31 are both coaxially fitted with a second pulley 38. A second synchronous belt 33 is connected between the two second pulleys 38. The second pulley 38 is connected to the second synchronous belt 33, which is used for transmission. A gear 34 is coaxially fitted on the lower end of the transmission column 32. A toothed plate 16 meshes with the outer side of the gear 34. The cooperation between the gear 34 and the toothed plate 16 drives the material blocking disc 37 to rotate. A connecting frame 19 is fixedly installed at the rear end of the toothed plate 16. The connecting frame 19 is used to fix the toothed plate 16. The end of the connecting frame 19 is fixed to the moving table 14.

[0032] During centrifugal screening, servo motor 18 drives cylinder 13 to rotate via synchronous belt 22, which in turn drives centrifugal screen cylinder 12 inside cylinder 13 to rotate, thus centrifuging and screening the raw materials inside centrifugal screen cylinder 12. At the same time, servo motor 15 drives top frame 26 to rotate, which in turn drives push frame 25 to move, allowing moving table 14 to swing back and forth on bearing rod 23, which in turn drives the rotating centrifugal screen cylinder 12 to swing back and forth, allowing the raw materials to move fully in the centrifugal screen cylinder 12 for centrifugal screening. When moving table 14 drives centrifugal screen cylinder 12 to swing back and forth, it also drives toothed plate 16 to move back and forth, which in turn drives gear 34 meshing with toothed plate 16 to rotate, allowing transmission column 32 to pass through The second synchronous belt 33 drives the material blocking disc 37 on the transmission shaft 31 to rotate in the disc body 10. When the material in the hopper 7 is connected to the discharge hole 36 and the discharge port of the hopper 7, the material is fed into the centrifugal screen cylinder 12. When they are misaligned, the material is prevented from being fed into the centrifugal screen cylinder 12. This allows the material to be fed into the centrifugal screen cylinder 12 intermittently in small amounts to avoid excessive material accumulation in the centrifugal screen cylinder 12, which would affect the screening. The screened material will fall into the hopper seat 1 through the gap between the centrifugal screen cylinder 12 and the cylinder shell 13 and be discharged. At the same time, the second solenoid valve 30 on the hopper 7 can be closed to stop feeding, and the first solenoid valve 4 on the centrifugal screen cylinder 12 can be opened to allow the screened material in the centrifugal screen cylinder 12 to fall into the inclined guide tube 20 and be guided out.
