Description

Technical Field

[0001] The invention relates to the technical field of mixers, in particular to a quick mixing device before bio-fertilizer fermentation. Background Art

[0002] Biofertilizer refers to fertilizer derived from biological organic matter, such as plants and animals, obtained through fermentation, composting or other treatment methods. The biofertilizer raw materials need to be mixed before fermentation.

[0003] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials. During the mixing process, it can also increase the contact surface area of ​​the materials to promote chemical reactions and accelerate physical changes.

[0004] When the existing mixer mixes the bio-fertilizer raw materials, since the bio-fertilizer raw materials are crushed in advance, when they are poured into the mixer for mixing, the crushed bio-fertilizer raw materials will agglomerate during transportation and storage.

At the same time, multiple bio-fertilizer raw materials are directly mixed by the mixer, which requires a long mixing time to complete the mixing. Therefore, the present application provides a bio-fertilizer pre-fermentation rapid mixing device to meet the needs. Summary of the invention

[0046] like Figure 5 and Figure 6 As shown, the screening structure 5 includes a screening drum bracket 53 rotatably connected to the outer wall of the mixing drum 3, one end of the screening drum bracket 53 is hinged to the outer wall of the mixing drum 3, and the other end is detachably connected to the buckle on the outer wall of the mixing drum 3. When it is necessary to clean the circulation unit 8 and the vibration structure 9, the buckle can be opened, the entire screening drum 51 is rotated open, and the mixing drum feed port 36 and the vibration structure 9 are exposed, so that the staff can clean the bio-fertilizer raw material residues and debris in the bio-fertilizer raw materials. One side of the screening drum bracket 53 is fixedly connected to the screening drum 51, and a screening port 52 is opened at one end of the screening drum 51. The end of the screening drum 51 close to the screening port 52 is fixedly connected to the feed pipe 6 connected thereto, and the screening port 52 is connected to the feed pipe 6. 6 is connected, the biofertilizer principle passes through the curved feed pipe 6 and enters the interior of the sieve barrel 51 through the sieve opening 52, the interior of the sieve barrel 51 is fixedly connected with rotating convex rings 55 on both sides, the interior of the sieve barrel 51 is rotatably connected with a sieve shaft 54, one end of the sieve barrel 51 is fixedly connected with a motor, one end of the sieve shaft 54 ​​passes through the sieve barrel 51 and is fixedly connected with the output end of the motor, the motor drives the sieve shaft 54 ​​to rotate, thereby breaking up the biofertilizer raw materials entering the sieve barrel 51, the circulation unit 8, the circulation unit 8 is located inside the sieve barrel 51, the circulation unit 8 is rotatably connected to the two ends of the sieve barrel 51, and the biofertilizer raw materials after being broken up by the sieve shaft 54 ​​can be circulated and screened through the circulation unit 8.

[0047] like Figure 6 and Figure 7 As shown, the circulation unit 8 includes a circulation drum 81 rotatably connected to both ends of the screening drum 51, and a plurality of rows of evenly arranged first material ports 82 are opened on the surface wall of the circulation drum 81. After the biofertilizer raw materials are scattered by the screening shaft 54, they will be scattered below the circulation drum 81. The biofertilizer raw materials that meet the size will enter the next process through the first material port 82, and the biofertilizer raw materials that do not meet the size will be driven by the rotating circulation drum 81 to rotate to the top of the screening shaft 54, and fall to the screening shaft under the action of gravity. The breaking process continues on the material rotating shaft 54 ​​until all the biofertilizer raw materials meet the requirements and pass through the first material port 82. The inner surface wall of the circulation cylinder 81 is fixedly connected with a threaded spiral arc plate 85. The spiral arc plate 85 is a plurality of arc plate structures distributed in a threaded manner. The biofertilizer raw materials entering the screening port 52 can be carried to the inside of the screening cylinder 51 through the spiral arc plate 85 to prevent the biofertilizer raw materials from accumulating at the screening port 52. The surface wall of the spiral arc plate 85 is provided with a plurality of arc grooves 851. The arc grooves 85 1 can effectively increase the extrusion force between the spiral arc plate 85 and the biofertilizer raw material. The two ends of the circulation drum 81 are provided with rotating annular grooves 84 adapted to the rotating convex ring 55. The circulation drum 81 and the screening drum 51 are rotatably connected through the rotating annular grooves 84 and the rotating convex ring 55.

Since the transmission gear 76 is meshed and connected with the circulation gear 83, the rotating transmission gear 76 will drive the circulation drum 81 installed on the circulation gear 83 to rotate on the rotating convex ring 55, and then the circulation drum 81 can synchronously circulate and screen the biofertilizer raw materials during the mixing process.

[0048] like Figures 8 to 10 and Fig.12As shown, the vibration structure 9 includes a vibration plate 91 hinged at one end of the mixing barrel feed port 36, and a plurality of rows of uniform second material ports are provided on the surface of the vibration plate 91. Qualified biofertilizer raw materials passing through the first material port 82 on the circulation barrel 81 will fall into the surface of the vibration plate 91. The specifications of the second material port are consistent with those of the first material port 82. The biofertilizer raw materials circulated and screened by the circulation barrel 81 will be pre-mixed during the vibration process of the vibration plate 91. A vibration groove 361 is provided on one side of the mixing barrel feed port 36. The vibration groove 361 provides an installation space for the second elastic sheet 94. A vibration mounting sheet 93 corresponding to the vibration mounting sheet 93 is fixedly connected to one side of the vibration plate 91 close to the vibration groove 361. Symmetrical second elastic sheets 94 are fixedly connected to the surfaces of the vibration mounting sheet 93 on both sides. When the second elastic sheet 94 is deformed and restored, the vibration mounting sheet 93 will be driven to shake, thereby driving the vibration plate 91 to shake, so that the biofertilizer raw materials passing through the vibration plate 91 are vibrated and mixed. The surface of one end of the vibration plate 91 close to the vibration mounting sheet 93 is fixed. A plurality of first elastic sheets 92 are connected, and the position of the first elastic sheet 92 corresponds to the first material port 82.

By integrally forming them by die-casting, the strength of the first elastic sheet 92 and the second elastic sheet 94 can be increased, the production efficiency is high, and the production cost is reduced. During the rotation of the circulation drum 81, the edge of the first material port 82 will squeeze the first elastic sheet 92, and the first elastic sheet 92 will squeeze the vibration plate 91 downward while deforming. The squeezed vibration plate 91 will drive the vibration mounting sheet 93 to squeeze the second elastic sheet 94 for compression deformation. When the first material port 82 rotates to above the first elastic sheet 92, the squeezing of the first elastic sheet 92 will be released. At this time, the second elastic sheet 94 will recover its deformation after there is no squeezing force, driving the vibration mounting sheet 93 to move upward. In this process, the first material port 82 will repeat the first elastic sheet 92 to form a cycle. The second elastic sheet 94 drives the vibration plate 91 to move up and down during the deformation and recovery process, thereby causing the vibration plate 91 to vibrate back and forth.

[0049] like Fig.13As shown, the second elastic sheet 94 is mainly composed of a first mounting section 941, a deformation section 942 and a second mounting section 943. One side surface of the second mounting section 943 is fixedly connected to the inner surface of the vibration groove 361. The other end of the second mounting section 943 is connected to evenly arranged deformation sections 942. One end of each deformation section 942 is connected to the first mounting section 941. One end of the first mounting section 941 is fixedly connected to one side of the vibration mounting sheet 93. The number of deformation sections 942 is even and is symmetrically distributed on the surface of one side of the second mounting section 943. The thickness of the second mounting section 943 gradually changes from thin to thick from the middle to both sides. The vibration mounting sheet 93 is fixed to the inside of the vibration groove 361 through the second elastic sheet 94. When the vibration mounting sheet 93 is squeezed downward, the deformation section 942 of the second elastic sheet 94 below the vibration mounting sheet 93 will be compressed and bent, while the deformation section 942 of the second elastic sheet 94 above the vibration mounting sheet 93 will be stretched and bent.

[0050] like Fig.11 As shown, the first elastic sheet 92 is mainly composed of a contact section 921, an extrusion section 922, a reset section 923 and a support section 924. One end of the contact section 921 is fixedly connected to the upper surface of the vibration plate 91, and the other end is connected to the extrusion section 922. One end of the extrusion section 922 is connected to the reset section 923. The highest end horizontal position of the extrusion section 922 is slightly higher than the lowest end horizontal position of the circulation drum 81. Therefore, during the rotation of the circulation drum 81, the first material port 82 will cyclically extrude the extrusion section 922. The end of the reset section 923 away from the extrusion section 922 is fixedly connected to the side of the vibration plate 91. Two support sections 924 with the same structure are connected to the opposite surface of the vibration plate 91 and the contact section 921. The thickness of the contact section 921 gradually changes from thick to thin from the end close to the vibration plate 91 toward the extrusion section 922. The thickness of the extrusion section 922 gradually changes from thin to thick from the middle to both ends, and the thickness of the reset section 923 gradually changes from thin to thick from one end close to the extrusion section 922 to the side of the vibration plate 91. When the first material port 82 extrude the side of the extrusion section 922, one end of the extrusion section 922 will pull the contact section 921 to deviate toward the surface of the vibration plate 91, and at the same time, the other end of the extrusion section 922 will push the reset section 923 to deviate in the direction away from the vibration plate 91, so that the entire first elastic sheet 92 drives the vibration plate 91 to deviate. When the deformation needs to be restored, the reset section 923 will restore the deformation toward the side of the vibration plate 91, and the contact section 921 will restore the deformation in the direction away from the surface of the vibration plate 91. At the same time, the support section 924 also restores the deformation, so that the entire first elastic sheet 92 returns to its initial position.

[0051] like Figure 2 and Figure 3As shown, one side of the discharge baffle 4 is fixedly connected with a sealing plate 42, one side of the discharge baffle 4 is hinged with the outer wall of the mixing barrel 3, and the other end is clamped with the outer wall of the mixing barrel 3, the sealing plate 42 is adapted to the discharge port 33 of the mixing barrel, and the outer side of the sealing plate 42 is wrapped with sealing rubber, so when the discharge baffle 4 is closed, the sealing plate 42 can close the discharge port 33 of the mixing barrel to prevent the internal biofertilizer raw materials from being thrown out, and the two ends of the discharge baffle 4 are fixedly connected with corrugated rubber strips 41. When the discharge baffle 4 is closed, the corrugated rubber strips on both sides are The rubber strips 41 are compressed and contracted in the first installation groove 35. When it is necessary to discharge the material, the discharge baffle 4 is opened to expand the corrugated rubber strip 41. When the corrugated rubber strip 41 pulls the discharge baffle 4 to limit the position, the discharge baffle 4 and the two sides of the mixing barrel discharge port 33 are blocked to prevent the mixed biofertilizer raw materials from being discharged to both sides, which causes the problem of troublesome collection of the biofertilizer raw materials. The first installation groove 35 is opened at the position corresponding to the outer wall of the mixing barrel 3 and the corrugated rubber strip 41. The first installation groove 35 The corrugated rubber strip 41 is used to store the shrunk corrugated rubber strip 41. The side of the corrugated rubber strip 41 away from the discharge baffle 4 is fixedly connected to the top of the first mounting groove 35. The two ends of the corrugated rubber strip 41 are respectively connected to the surface of the discharge baffle 4 and the top of the first mounting groove 35. The corrugated rubber strip 41 is a fan-shaped structure. The corrugated rubber strip 41 with a fan-shaped structure is used to adapt to the fan-shaped areas on both sides after the discharge baffle 4 is opened. The corrugated rubber strip 41 is composed of a plurality of groups of connecting strips 411 and compression strips 412 connected end to end in sequence. The connecting strip 411 is made of a hard material. The compression strip 412 is made of rubber and is fixedly connected to both sides of the connecting strip 411. The thickness of the compression strip 412 gradually changes from thin to thick from the middle to both ends. The connecting strip 411 is used to connect with the next group of compression strips 412. At the same time, it can increase the stability of the corrugated rubber strip 41 and avoid the position displacement of the corrugated rubber strip 41 when it is compressed. When the compression strip 412 is compressed, it will bend and deform, so that several groups of connecting strips 411 and compression strips 412 can be compressed in the first mounting groove 35.

[0052] The working principle provided by the present invention is that when the biofertilizer raw materials need to be mixed, the biofertilizer principle passes through the curved feed pipe 6 and the screen opening 52 into the circulation drum 81 inside the screen drum 51, and the mixing motor 2 and the motor on the screen drum 51 are started. When the mixing motor 2 drives the transmission shaft 71 to rotate, it will drive the scraper bracket 74 installed on the mounting support rod 72 to rotate, thereby driving the transmission gear 76 to rotate. Since the transmission gear 76 is meshed and connected with the circulation gear 83, the rotating transmission gear 76 will drive the circulation drum 81 installed on the circulation gear 83 to rotate on the rotating convex ring 55, and the circulation drum 81 will drive the internal The bio-fertilizer raw materials at the bottom of the screening drum 51 rotate, and at the same time, the motor on the screening drum 51 drives the screening shaft 54 ​​to rotate, so as to break up the bio-fertilizer raw materials entering the screening drum 51. After being broken up by the screening shaft 54, the bio-fertilizer raw materials will be scattered below the circulation drum 81, and the bio-fertilizer raw materials that meet the size will enter the next process through the first material port 82, and the bio-fertilizer raw materials that do not meet the size will be driven by the rotating circulation drum 81 to rotate above the screening shaft 54, and under the action of gravity, fall onto the screening shaft 54 ​​to continue the breaking process, until all the bio-fertilizer raw materials meet the requirements and pass through the first material port 82.

[0053] The qualified biofertilizer raw materials passing through the first material port 82 on the circulation cylinder 81 will fall onto the surface of the vibration plate 91. The specifications of the second material port are consistent with those of the first material port 82. The biofertilizer raw materials circulated and screened by the circulation cylinder 81 will be pre-mixed during the vibration process of the vibration plate 91. During the rotation of the circulation cylinder 81, the edge of the first material port 82 will squeeze the first elastic sheet 92. During the squeezing, one end of the squeezing section 922 will pull the contact section 921 to deflect toward the surface of the vibration plate 91, and at the same time, the other end of the squeezing section 922 will push the reset section 923 to deflect away from the vibration plate 91, so that the entire first elastic sheet 92 drives the vibration plate 91 to deflect. When it is necessary to restore the deformation, the reset section 923 will restore the deformation toward the side of the vibration plate 91, and the contact section 921 will restore the deformation toward the direction away from the surface of the vibration plate 91. At the same time, the support section 924 also restores the deformation, so that the entire first elastic sheet 92 returns to the initial position. The first elastic sheet 92 When the vibration plate 91 is deformed, it will squeeze the vibration plate 91 downward. The squeezed vibration plate 91 will drive the vibration mounting piece 93 to squeeze the second elastic piece 94 and compress and deform. When the vibration mounting piece 93 is squeezed downward, the deformation section 942 of the second elastic piece 94 below the vibration mounting piece 93 will be compressed and bent, and the deformation section 942 of the second elastic piece 94 above the vibration mounting piece 93 will be stretched and bent. When the first material port 82 rotates to above the first elastic piece 92, its edge is not released from the first elastic piece 92, and the squeezing of the first elastic piece 92 will be released. At this time, the deformation section 942 of the second elastic piece 94 will restore the deformation and drive the vibration mounting piece 93 to move upward. In this process, the first material port 82 will repeat the first elastic piece 92 to form a cycle. The second elastic piece 94 drives the vibration plate 91 to move up and down during the deformation and recovery process, so that the vibration plate 91 vibrates back and forth, thereby vibrating and mixing the biofertilizer raw materials passing through the vibration plate 91.

[0054] After vibration and mixing, the biofertilizer raw materials will pass through the second material port on the vibration plate 91 and fall into the mixing barrel 3. The mixing motor 2 drives the transmission shaft 71 to rotate, and the transmission shaft 71 drives the spiral mixing sheet 73 installed on the mounting support rod 72 to rotate, so as to stir and mix the biofertilizer raw materials in the mixing barrel 3. After mixing, the discharge baffle 4 is opened, and the biofertilizer raw materials in the mixing barrel 3 are driven by the scraper plate 75 to be discharged from the mixing barrel discharge port 33.
