Description

Technical Field

[0001] This invention relates to the field of organic fertilizer production technology, and in particular to a mixer for processing organic fertilizer. Background Technology

[0002] Organic fertilizer refers to a type of fertilizer derived from the metabolic secretions (excrement) and remains of animals and plants, industrial waste (distillers' grains, bone meal, and medicinal herb residues), and other biological products (microbial fertilizers). Through the action of microorganisms, it undergoes decomposition, fermentation, and other non-toxic and harmless reactions. Its main characteristics are its richness in organic matter and various nutrients, which can improve soil nutrient conditions and increase crop yields. The production process of organic fertilizer typically involves using a mixer to combine various raw materials.

[0003] Chinese utility model patent CN214076440U discloses a horizontal twin-shaft mixer for organic fertilizer processing. The mixer is driven by a motor to rotate the first rotating shaft and the drive gear. The drive gear drives the driven gear to rotate, and the driven gear drives the second rotating shaft to rotate. Thus, the second rotating shaft and the first rotating shaft drive the mixing blades to rotate and perform mixing. During the mixing process, the organic fertilizer is continuously pushed to the left by the spiral structure of the mixing blades, which makes it easy for the organic fertilizer to slide out from the left end of the mixing base later.

[0004] When using the twin-shaft mixer disclosed in the above utility model patent to mix the raw materials of organic fertilizer, the material moves in one direction when the mixing blades rotate under the drive of the first and second spiral shafts, and the mixing blades push the material to one side of the mixing shell, causing the material to accumulate on one side of the mixing shell, resulting in uneven mixing of the material. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a mixer for organic fertilizer processing, which solves the problem of uneven material mixing in existing technologies.

[0006] According to an embodiment of the present invention, a mixer for organic fertilizer processing includes a frame and a mixing chamber mounted on the frame. The mixing chamber has a rotatable outer shaft, and the frame has a first motor drivenly connected to the outer shaft. The outer shaft has multiple mounting seats spaced apart. Each mounting seat has a mixing blade that can rotate radially around the outer shaft. Each mixing blade has an eccentric shaft. Each mounting seat also has a movable block that can move axially along the outer shaft. The movable block has a groove, and the eccentric shaft extends into the groove and abuts against the movable block. The outer shaft contains a rotatable inner shaft, and the outer shaft has a second motor drivenly connected to the inner shaft. The inner shaft includes multiple shaft bodies. The shafts are arranged in a row inside the inner shaft. Each shaft includes a drive rod and connecting rods respectively disposed at both ends of the drive rod. The axial direction of the drive rod is not parallel to the axial direction of the outer shaft. The axial direction of the connecting rod coincides with the axial direction of the outer shaft. Two connecting rods of any two adjacent shafts are fixedly connected to each other. A rotatable drive cylinder is sleeved on the drive rod, and a transmission rod is provided on the drive cylinder. One end of the drive cylinder has an extension portion extending away from the drive rod. One end of the transmission rod is rotatably connected to the movable block, and the other end is provided with a first spherical head. The end of the extension portion away from the drive rod is provided with a first mounting groove that mates with the first spherical head.

[0007] Compared with the prior art, the present invention has the following beneficial effects: the first motor drives the outer shaft to rotate, causing the stirring blades to rotate axially around the outer shaft to stir the material in the mixing tank. At the same time, the second motor drives the inner shaft to rotate inside the outer shaft. When the inner shaft rotates, the drive rod rotates axially around the outer shaft and drives the drive cylinder to move. During the movement of the drive cylinder, the transmission rod drives the movable block to move back and forth on the mounting base. During the movement of the movable block, the stirring blades are driven to rotate back and forth by the eccentric shaft and the sliding groove. This makes the stirring blades perform a compound motion of axial rotation and radial reciprocating rotation around the outer shaft when stirring the material. When the material is stirred by the stirring blades, it moves in multiple different directions, which speeds up the mixing of the material and avoids the accumulation of material in some areas of the mixing tank. This solves the technical problem of uneven material mixing and produces the technical effect of improving the material mixing efficiency and ensuring uniform material mixing.

[0016] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 7 As shown in the figure, this embodiment of the invention proposes a mixer for organic fertilizer processing, which is used to mix and stir multiple raw materials during the organic fertilizer processing process.

[0018] Please refer to Figures 1 to 5The organic fertilizer processing mixer includes a frame 1 and a mixing box 2 mounted on the frame 1. The mixing box 2 is provided with a rotatable outer shaft 3, and the frame 1 is provided with a first motor 11 that is drively connected to the outer shaft 3. The outer shaft 3 is provided with a plurality of mounting seats 4 at intervals. Each mounting seat 4 is provided with a stirring blade 5 that can rotate radially around the outer shaft 3. When the outer shaft 3 rotates under the drive of the first motor 11, the stirring blade 5 rotates axially around the outer shaft 3 and stirs the material in the mixing box 2. The stirring blade 5 is provided with an eccentric shaft 51. The mounting base 4 is also provided with a movable block 6 that can move along the axial direction of the outer shaft 3. The movable block 6 is provided with a sliding groove 61, and the eccentric shaft 51 extends into the sliding groove 61 and abuts against the movable block 6. The outer shaft 3 is provided with a rotatable inner shaft 7, and the outer shaft 3 is provided with a second motor 31 that is driven and connected to the inner shaft 7. The inner shaft 7 includes a plurality of shaft bodies 71, which are arranged in a row inside the inner shaft 7. Each shaft body 71 includes a drive rod 72 and connecting rods 73 respectively provided at both ends of the drive rod 72. The axial direction of the drive rod 72 is not parallel to the axial direction of the outer shaft 3. The axial direction of the connecting rod 73 coincides with the axial direction of the outer shaft 3, and any two adjacent shaft bodies 71 are fixedly connected to each other. A rotatable drive cylinder 74 is sleeved on the drive rod 72, and a transmission rod 75 is provided on the drive cylinder 74. One end of the drive cylinder 74 has a direction away from the drive rod 72. The extension 76 extends in the direction of 2. One end of the transmission rod 75 is rotatably connected to the movable block 6, and the other end is provided with a first spherical head 77. The end of the extension 76 away from the drive rod 72 is provided with a first mounting groove that cooperates with the first spherical head 77. The inner shaft 7 is driven to rotate by the second motor 31, which in turn drives the drive cylinder 74 to move through the drive rod 72. During the movement of the drive cylinder 74, the transmission rod 75 drives the movable block 6 to reciprocate along the axial direction of the outer shaft 3 on the mounting base 4. During the movement of the movable block 6, the stirring blade 5 is driven to reciprocate radially around the outer shaft 3 through the cooperation of the eccentric shaft 51 and the sliding groove 61. That is, the stirring blade 5 performs a compound motion of axial rotation and radial reciprocating rotation around the outer shaft 3 during the stirring of materials, so that the materials move in different directions under the action of the stirring blade 5, thereby accelerating the mixing efficiency of the materials.

[0019] Specifically, the working process of the organic fertilizer processing mixer provided in this embodiment is as follows: Various different raw materials are added to the mixing tank 2 in proportion. The first motor 11 and the second motor 31 are turned on respectively. The second motor 31 is connected to the power supply via a conductive slip ring. The first motor 11 drives the outer shaft 3 to rotate and drives the stirring blades 5 to rotate axially around the outer shaft 3. The second motor 31 drives the inner shaft 7 to rotate within the outer shaft 3 and drives the stirring blades 5 to reciprocate radially around the outer shaft 3. During the mixing process, the stirring blades 5 perform a combined motion of axial rotation and radial reciprocating rotation around the outer shaft 3, causing the material in the mixing tank 2 to move in multiple different directions under the action of the stirring blades 5, thereby accelerating material mixing and preventing material accumulation in certain areas of the mixing tank 2. After the material is evenly mixed, the first motor 11 and the second motor 31 are turned off, and the mixed material is removed from the mixing tank 2. The organic fertilizer processing mixer provided in this embodiment uses the mixing blades 5 to perform a combined motion of axial rotation around the outer shaft 3 and radial reciprocating rotation around the outer shaft 3 to mix the material, thereby improving the mixing efficiency of the material and preventing the material from accumulating, thus ensuring that the material is mixed evenly.

[0020] like Figure 1 and Figure 2 As shown, the mixing tank 2 is provided with two rotatable outer shafts 3 spaced apart. Each of the two outer shafts 3 is equipped with a drive gear 32. The mixing tank 2 also has two meshing transmission gears 21, with each transmission gear 21 meshing one-to-one with the two drive gears 32. By providing two outer shafts 3 on the mixing tank 2, and connecting them via the drive gears 32 and transmission gears 21, when the first motor 11 drives one of the outer shafts 3 to rotate, both outer shafts 3 rotate simultaneously in opposite directions. Consequently, the stirring blades 5 on both outer shafts 3 simultaneously stir the material in the mixing tank 2, further improving the stirring efficiency of the organic fertilizer processing mixer.

[0021] like Figure 4 , Figure 5 and Figure 6 As shown, the stirring blade 5 is provided with a second spherical head 52, and the mounting base 4 is provided with a second mounting groove that mates with the second spherical head 52. The stirring blade 5 is rotatably connected to the mounting base 4 through the engagement of the second spherical head 52 and the second mounting groove, allowing the stirring blade 5 to rotate smoothly on the mounting base 4. At the same time, it prevents the stirring blade 5 from sliding radially along the outer shaft 3, which would cause the stirring blade 5 to vibrate, thus keeping the stirring blade 5 stable during the stirring of materials.

[0022] Please combine Figure 5 and Figure 6 The mounting base 4 is also provided with a limiting groove 41 that cooperates with the movable block 6. The length direction of the limiting groove 41 is consistent with the moving direction of the movable block 6. The limiting groove 41 provided on the mounting base 4 is used to limit the direction of movement of the movable block 6 on the mounting base 4 and the stroke of the movable block 6 when moving on the mounting base 4, so as to prevent the movable block 6 from deviating from the preset direction or detaching from the mounting base 4 when moving.

[0023] In detail, the mounting base 4 is further provided with a guide rod 42 parallel to the limiting groove 41, and the movable block 6 is provided with a guide hole 62 that cooperates with the guide rod 42. The movable block 6 is installed onto the mounting base 4 by the cooperation of the guide rod 42 and the guide hole 62, so that the connection between the movable block 6 and the mounting base 4 is reliable and the stability of the movable block 6 when moving on the mounting base 4 is improved.

[0024] Please refer to Figure 3 and Figure 6 Each connecting rod 73 has a connecting flange 78 at its end away from the driving rod 72, and the connecting flanges 78 on any two adjacent shafts 71 are mated together. The shafts 71 are connected by the connecting flanges 78, ensuring a secure fit between adjacent shafts 71 and ensuring that the connecting rods 73 on each shaft 71 are coaxial. This allows each stirring blade 5 to rotate smoothly and simultaneously under the drive of the inner shaft 7 when the inner shaft 7 rotates, which helps improve the structural stability of the mixer for organic fertilizer processing.

[0025] like Figure 2 and Figure 3 As shown, an arc-shaped plate 53 is provided at the end of the stirring blade 5 away from the outer shaft 3, and the arc-shaped plate 53 is detachably connected to the stirring blade 5. Providing the arc-shaped plate 53 at the end of the stirring blade 5 further enhances the stirring effect of the stirring blade 5 on the material. Furthermore, the riveting of the arc-shaped plate 53 to the stirring blade 5 ensures a secure connection while facilitating the disassembly of the arc-shaped plate 53. This allows for the replacement of damaged or deformed arc-shaped plates 53, simplifying the maintenance of the organic fertilizer processing mixer.

[0026] like Figure 1 , Figure 2 and Figure 7As shown, the mixing tank 2 has a feed inlet 22 at the top, and a feed hopper 23 is also provided on the mixing tank 2, with the feed hopper 23 communicating with the feed inlet 22. The material to be mixed is added into the mixing tank 2 through the feed inlet 22, and the feed hopper 23 on the mixing tank 2 is used to guide the material into the feed inlet 22, preventing the material from falling out of the mixing tank 2 during the process of entering the mixing tank 2.

[0027] Please combine Figure 2 and Figure 7 The bottom of the mixing tank 2 is provided with two discharge ports 24 spaced apart along the axial direction of the outer shaft 3. The mixing tank 2 is also provided with two solenoid valves 25, and the two solenoid valves 25 are connected to the two discharge ports 24 in a one-to-one correspondence. The discharge ports 24 at the bottom of the mixing tank 2 are for discharging the mixed materials in the mixing tank 2. The two discharge ports 24 are provided to improve the efficiency of material discharge. The solenoid valves 25 are respectively provided at the openings of the discharge ports 24 to control the opening or closing of the discharge ports 24, which facilitates the use of the mixer for organic fertilizer processing.

[0028] In this embodiment, the mixing tank 2 is further provided with a rotatable conveying shaft 8 and a third motor 26 connected to the conveying shaft 8. The conveying shaft 8 is arranged parallel to the outer shaft 3, and two spiral blades 81 with opposite rotation directions are spaced apart on the conveying shaft 8, with the two spiral blades 81 located directly above the two discharge ports 24 respectively. The third motor 26 is connected to the power supply using a conductive slip ring. When the conveying shaft 8 rotates under the drive of the third motor 26, it drives the spiral blades 81 to rotate. When the spiral blades 81 rotate, they convey the material in the mixing tank 2 along the axial direction of the conveying shaft 8, so that the material moves closer to or away from the discharge ports 24. In turn, the spiral blades 81 assist the mixing blades 5 in mixing the material, further improving the mixing efficiency, or transporting the mixed material to the discharge ports 24 to quickly discharge the material from the mixing tank 2, avoiding material retention in the mixing tank 2.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
