Description

Technical Field

[0001] The invention relates to the field of fertilizer production, and in particular to a composite microbial fertilizer production device. Background Art

[0002] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials. Common mixers are divided into gas and low-viscosity liquid mixers, medium- and high-viscosity liquid and paste mixing machines, thermoplastic material mixers, powdered and granular solid material mixing machines, etc. Mixers are efficient and fast and are widely used in many industries. The production process of compound microbial fertilizers mainly includes crushing, mixing, granulation, drying, screening, metering and packaging. That is to say, when producing compound microbial fertilizers, various raw materials must first be cleaned and crushed, and then the various raw materials must be mixed and granulated according to the ratio. During mixing, the crushed raw materials will inevitably clump due to stacking and transportation, which makes the mixing uneven, thus affecting subsequent processing. A Chinese patent document with application publication number CN 110917948 A discloses a mixing device for producing organic fertilizers. The device is provided with a crushing assembly and a crushing disk inside a housing. The crushing assembly and the crushing disk cooperate to crush the agglomerated materials. However, most of the raw materials of organic fertilizers are relatively moist, and it is more likely to increase the humidity after stacking. The extrusion crushing method has an unsatisfactory crushing effect on the agglomerated materials, and the materials after extrusion and crushing are still concentrated in the same position after falling, resulting in an unsatisfactory mixing effect.

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0052] like Figures 1 to 9 As shown, a composite microbial fertilizer production device provided by an embodiment of the present invention includes a housing 100, a stirring assembly 600, an auger assembly 700, a material distribution assembly 800 and a material leveling assembly 900;

[0053] The housing 100 is provided with a loading port 301 at the top and a discharging port 200 at the bottom. The discharging port 200 is blocked during operation and can be discharged by opening the discharging port 200. A feeding cylinder 110 is provided at the center of the housing 100, and the bottom of the feeding cylinder 110 is connected to the internal space of the housing 100. The stirring assembly 600 is provided at the bottom of the housing 100 and is configured to stir the material; the auger assembly 700 is provided inside the feeding cylinder 110 and is configured to transport the material at the bottom of the housing 100 upward along the feeding cylinder 110; the material distribution assembly 800 is provided at the top of the feeding cylinder 110 and is configured to divide the material transported by the auger assembly 700 into a plurality of feeding points evenly distributed along the circumferential direction and feed downward; the material leveling assembly 900 is provided outside the feeding cylinder 110 and below the material distribution assembly 800 and is configured to break up the material falling from the material distribution assembly 800 and disperse it to the surroundings.

[0054] The material leveling assembly 900 includes a rotating frame 910 and a plurality of grid assemblies 930. The rotating frame 910 is coaxially arranged on the outside of the feeding barrel 110 and can rotate. The rotating frame 910 includes a central barrel 915, an outer ring body 914 and a plurality of connecting rods 912. The outer ring body 914 is located on the outside of the central barrel 915 and is coaxial with the central barrel 915. The plurality of connecting rods 912 are evenly distributed along the circumferential direction and connected between the central barrel 915 and the outer ring body 914 along the radial direction. The central barrel 915 is rotatably sleeved on the outside of the feeding barrel 110. The grid assemblies 930 are arranged on the connecting rods 912 in a one-to-one correspondence. Each grid assembly 930 includes an upper grid and a lower grid. The upper grid and the lower grid are overall in a V-shaped structure with twisted sides. The opening directions of the upper grid and the lower grid of the same grid assembly 930 are opposite, the opening directions of all upper grids are the same, the opening directions of all lower grids are the same, and the opening direction of the upper grid is consistent with the rotation direction of the rotating frame 910. Specifically, the grille assembly 930 includes a plurality of frame rods, which are arranged at intervals along the extension direction of the connecting rod 912. The frame rods include a ring and an upper rod body and a lower rod body respectively connected to the upper and lower ends of the ring. The ring is sleeved on the connecting rod 912. The upper rod body of the frame rod on each connecting rod 912 together forms an upper grille, and the lower rod body of the frame rod on each connecting rod 912 together forms a lower grille.

[0055] When in use, the various raw materials to be mixed are put into the housing 100 from the feeding port 301 according to the ratio requirements, and then the auger assembly 700 and the material leveling assembly 900 are started. The auger assembly 700 transports the materials at the bottom of the housing 100 from bottom to top along the feeding tube 110. When the materials are transported to the top of the feeding tube 110, the materials are dropped downward through the material dividing assembly 800. As the material leveling assembly 900 rotates, the materials collide with the upper and lower grids to break up the agglomerated materials. At the same time, due to the twisted structure of the upper and lower grids, the materials are guided in different directions after being broken up, and then fall discretely to the inner bottom of the housing 100, and the materials are mixed more evenly by cooperating with the stirring assembly 600 to stir the materials. At the same time, through multiple cycles of the auger assembly 700, the materials are mixed more evenly. The present invention cooperates with the auger assembly 700, the material distribution assembly 800 and the material leveling assembly 900, and utilizes the special structure of the upper grid and the lower grid of the material leveling assembly 900 to effectively break up the material and disperse it around, so that the material falls discretely to the bottom of the outer shell 100 and is evenly mixed under the action of the stirring assembly 600, with a good mixing effect.

[0056] In a further embodiment, the material dividing assembly 800 includes a screening structure, a first collecting chamber 804 and a second collecting chamber 807; the screening structure is configured to divide the materials transported to the top by the auger assembly 700 into Class I materials and Class II materials, and the volume of Class I materials is smaller than the volume of Class II materials. The first collecting chamber 804 and the second collecting chamber 807 are both located below the screening structure and are alternately arranged along the circumferential direction, the first collecting chamber 804 receives Class I materials, and the second collecting chamber 807 receives Class II materials; the first collecting chamber 804 is provided with a first discharge port 806, and the first discharge port 806 is located on the side, and the second collecting chamber 807 is provided with a second discharge port 808, and the second discharge port 808 is located at the bottom.

[0057] The composite microbial fertilizer production device of the present invention also includes a first control component, which is configured to cause the first discharge port 806 and the second discharge port 808 to discharge materials alternately during the rotation of the rotating frame 910, and to cause the material in the first collecting chamber 804 to rotate around the axis of the feed cylinder 110 in the opposite direction of the rotation of the rotating frame 910 and be thrown out from the first discharge port 806.

[0058] Among them, the screening structure includes a material guide channel, and a plurality of discharge ports 801 are arranged on the top of the feed barrel 110. There are multiple material guide channels and they extend radially, and each material guide channel corresponds to a discharge port 801; the first collecting chamber 804 is aligned with the material guide channel, and the second collecting chamber 807 is located between two adjacent material guide channels; two inclined screens 803 with close upper ends are connected to the bottom of each material guide channel, and drop ports are arranged on both sides of the material guide channel, and the drop ports are aligned with the screen 803. After the materials falling from the drop ports of the material guide channel are screened by the screen 803, one type of materials pass through the screen 803 and fall into the first collecting chamber 804, and the second type of materials slide from the outside of the screen 803 to the second collecting chamber 807.

[0059] It can be understood that, in terms of the degree of material agglomeration, small pieces of material have a small degree of agglomeration and are relatively more difficult to break up, while large pieces of material have large agglomerations and are easier to break up. According to the above rules, the materials transported to the top by the auger assembly 700 are divided into one type of material (referring to relatively small pieces of material or small agglomerates, which are specifically determined by the size of the sieve holes of the screen 803) and the second type of material (referring to large pieces of material that cannot be filtered by the screen 803), and the large pieces of material are made to fall vertically and the small pieces of material are rotated and thrown out; large pieces of material are larger in size and are easier to break up, and the vertical falling method has high dropping efficiency, while small pieces of material have small agglomerates and are not easy to break up. After the small pieces of material are rotated and thrown out, they collide with the upper and lower grilles to increase the impact force, which facilitates the breaking up of the small pieces of material.

[0060] Specifically, refer to Figure 5 , Figure 6 and Fig. 9The material distribution component 800 also includes a sleeve 830, which is located on the outside of the feed barrel 110 and is coaxial with the feed barrel 110. A partition 802 is arranged between the sleeve 830 and the feed barrel 110. There are multiple groups of partitions 802, two in each group, and a receiving plate is arranged under each group of partitions 802. Each group of partitions 802, the receiving plate and the sleeve 830 enclose the above-mentioned material guiding channel.

[0061] A blanking plate is also provided between the sleeve 830 and the feed barrel 110. The blanking plate is located below the partition 802. A number of vertical baffles are provided on the blanking plate. The vertical baffles separate the lower space between the sleeve 830 and the feed barrel 110 into the above-mentioned first collecting chamber 804 and the second collecting chamber 807. The screen 803 is provided above the vertical baffles and the upper ends of the two adjacent screens 803 are close to the material guide channel and connected to the receiving plate. Openings are provided between the receiving plate and the two adjacent partitions 802 to form the above-mentioned blanking port.

[0062] Further, see Figure 5 and Figure 6 As shown, the first control component includes a first discharge plate 810 and a second discharge plate 820, and a blanking channel 805 connected to the first discharge port 806 is arranged in the first collecting chamber 804. The blanking channel 805 is L-shaped and includes a vertical channel and a horizontal channel that are connected. A blocking plate 840 is arranged at the connection between the vertical channel and the horizontal channel. The blocking plate 840 can slide elastically along the circumference of the feeding cylinder 110 and initially block the connection between the vertical channel and the horizontal channel. The first discharge port 806 is the outlet of the horizontal channel; the first discharge plate 810 is arranged in the horizontal channel and can slide along the circumference of the feeding cylinder 110. 10 elastically slides in the circumferential direction, initially the first discharge plate 810 is close to the first discharge port 806, and when the first discharge plate 810 moves in the direction away from the first discharge port 806, it can drive the blocking plate 840 to move to open the connection between the vertical channel and the horizontal channel. Specifically, a slide groove 8051 is arranged on the blanking plate, and the slide groove 8051 is arc-shaped. The first discharge plate 810 is slidably arranged in the slide groove 8051, and the first discharge plate 810 and the slide groove 8051 are arranged at one end close to the first discharge port 806 with a first elastic member (not shown in the figure), and the first elastic member is preferably a spring.

[0063] The second discharge plate 820 is disposed in the second collecting chamber 807 and can slide elastically along the radial direction of the feeding cylinder 110. A through hole is disposed on the second discharge plate 820. Initially, the second discharge plate 820 is at the outer end limit position and the through hole is misaligned with the second discharge port 808. When the second discharge plate 820 is at the inner end limit position, the through hole is aligned with the second discharge hole. Specifically, a second elastic member (not shown in the figure) is disposed between the second discharge plate 820 and the blanking plate. Initially, the second elastic member makes the second discharge plate 820 at the outer end limit position. Preferably, the second elastic member is a spring.

[0064] A number of circumferentially evenly distributed first magnetic members 911 are arranged on the central tube 915 of the rotating frame 910. The number of the first magnetic members 911 is the same as the number of the first collecting chambers 804 or the second collecting chambers 807. The first magnetic members 911 can attract the first discharge plate 810 and the second discharge plate 820. Specifically, the first discharge plate 810 and the second discharge plate 820 can be made of ferromagnetic materials, or magnets can be arranged inside the first discharge plate 810 and the second discharge plate 820, and the magnets are attracted to the first magnetic members 911. During the rotation of the rotating frame 910, when the first magnetic member 911 is aligned with the first discharge plate 810, the first magnetic member 911 attracts the first discharge plate 810, and the first discharge plate 810 rotates with the rotating frame 910 under the action of the first magnetic member 911 and opens the blocking plate 840, and the material in the first collection chamber 804 falls into the horizontal channel. When the rotating frame 910 rotates to be separated from the first discharge plate 810, the first discharge plate 810 elastically resets and rotates and throws the material in the horizontal channel out of the first discharge port 806. When the rotating frame 910 rotates to the point where the first magnetic member 911 is aligned with the second discharge plate 820, the first magnetic member 911 attracts the second discharge plate 820, so that the second discharge plate 820 moves inward, the through hole of the second discharge plate 820 is aligned with the second discharge port 808, and the second discharge port 808 discharges material, so that during the rotation of the rotating frame 910, the first discharge port 806 and the second discharge port 808 alternately drop material.

[0065] In a further embodiment, the grid spacing of the grid assembly 930 can be adjusted, and the grid assembly 930 is configured such that the grid spacing when receiving the material in the first collection chamber 804 is smaller than the grid spacing when receiving the material in the second collection chamber 807. It can be understood that for the small pieces of material in the first collection chamber 804, since the material has a small degree of agglomeration, reducing the grid spacing is conducive to intercepting and breaking up the small pieces of material, and for the large pieces of material in the second collection chamber 807, if the grid spacing is too small, the contact area with the material becomes larger and the pressure is reduced, which is not conducive to breaking up the large pieces of material. Therefore, without affecting the capture of the large pieces of material, maintaining a larger grid spacing is conducive to breaking up the large pieces of material.

[0066] Specifically, the frame rods of the grille assembly 930 are divided into a first frame rod 931 and a second frame rod 932. The upper rod body and the lower rod body of the first frame rod 931 are fixed-length rods, and the upper rod body and the lower rod body of the second frame rod 932 are telescopic rods. There are three first frame rods 931, which are located on both sides and the middle respectively. The first frame rod 931 located in the middle and the tops of the first frame rods 931 located on both sides are respectively connected by elastic bars 933, and the second frame rod 932 located between the two first frame rods 931 slide relative to the elastic bars 933.

[0067] The first frame rod 931 and the second frame rod 932 can rotate relative to the connecting rod 912. The first frame rod 931 located at the innermost end is fixed in an axial position on the connecting rod 912. The remaining first frame rods 931 and the second frame rods 932 can slide axially along the connecting rod 912. A support spring 935 is connected between two adjacent frame rods. A sliding rod 920 is provided inside the connecting rod 912. The sliding rod 920 can slide along the axial direction of the connecting rod 912. The sliding rod 920 acts on the first frame rod 931 at the outermost end and is configured to drive the first frame rod 931 at the outermost end to rotate. The frame rod 931 slides, and under the action of the support spring 935, the slide bar 920 is in the outermost extreme position, and the grid spacing of the grid assembly 930 is the largest; a plurality of second magnetic members 809 with even circumferences are arranged on the outer side of the feed barrel 110, and the second magnetic members 809 correspond one-to-one to the first discharge port 801. The second magnetic member 809 can attract the slide bar 920 and then drive the slide bar 920 to move. The slide bar 920 can be made of ferromagnetic material, or a magnet can be arranged inside the slide bar 920, and the magnet can be attracted to the second magnetic member 809. When the rotating frame 910 rotates until the slide bar 920 is aligned with the second magnetic member 809, the second magnetic member 809 attracts the slide bar 920, causing the slide bar 920 to move inward.
