Description

Technical Field

[0001] This utility model is applied to the field of bio-organic fertilizer manufacturing, and relates to the mixing of organic fertilizer raw material particles, specifically a mixing device capable of continuous production. Background Technology

[0002] With advancements in organic fertilizer production technology, bio-organic fertilizers have evolved from large blocks to granules, facilitating uniform soil absorption. Simultaneously, the addition of nitrogen, phosphorus, potassium, and trace elements creates organic fertilizers that both improve soil structure and provide nutrients. The production steps for this type of organic fertilizer include fermentation and drying of the bio-raw material, crushing, batching, mixing, granulation, drying, sieving, and packaging. Crushing involves breaking the dried bio-raw material into fine particles to prepare the size for subsequent granulation. Batching involves adding nitrogen, phosphorus, potassium, and trace elements to the bio-raw material granules, mixing thoroughly, then moistening and extruding to form granules. After granulation, drying and sieving result in a finished organic fertilizer product with uniform particle size. Currently, most mixing devices on the market operate on a cyclical basis and cannot achieve continuous mixing.

[0003] Organic fertilizer production is inseparable from mixing devices, and there are many patent applications in this area. For example, CN108435066A discloses a fertilizer mixing device that can mix fertilizer evenly, solving the problem of uniform mixing. In paragraph

[0017] , the motor is powered on and starts. Under the action of the first bearing, it drives the rotating drum to rotate. Under the action of the first gear, the second gear rotates. The second rolling shaft drives the first mixing rod to rotate at high speed. The operator opens the stop valve to discharge the fertilizer. The problems with this technical solution are: 1) The first bearing assembly does not contact the rotating drum, so it cannot drive the rotating drum to rotate; 2) The gear is located in the housing and comes into contact with the mixing dust, which is easy to wear. The maintenance lubricating oil is easy to drip into the fertilizer, causing fertilizer contamination; 3) The stop valve is located in the housing, which is inconvenient to operate; 4) It is a periodic operation and cannot solve the problem of continuous production. CN113457507A discloses an organic bio-fertilizer mixing device with good mixing effect, integrating mixing and drying. The mixing rod is a linkage mechanism, resulting in good mixing of bio-fertilizer. However, bio-fertilizer easily enters the empty tube, causing obstruction of movement. This device also operates periodically, requiring the removal of the cover plate to take out the raw materials from the discharge port. CN115532152A discloses an organic fertilizer uniform mixing device that integrates mixing, crushing, heating, and fermentation. The mixing rod can swing up and down, the cutting blade crushes large pieces of fertilizer, and an anti-clogging component prevents the discharge port from clogging. It also operates periodically. Both of the above mixing devices have complex structures, high manufacturing costs, and are not competitive in the market. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a biological organic fertilizer raw material mixing device that mixes fine particulate raw materials during continuous operation. It has a simple structure, low manufacturing cost, and high mixing efficiency.

[0005] The technical solution adopted in this utility model is as follows: a biological organic fertilizer raw material mixing device includes a mixing component, a cylinder rotation component, a support component, and a valve component. The mixing component is located inside the cylinder of the cylinder rotation component and includes a rotating shaft and mixing rods. The mixing rods are fixedly connected to the rotating shaft and are evenly distributed around the circumference. The cylinder rotation component includes a cylinder, a transition gear, a main gear, and a gear ring. The gear ring is fixedly installed at the bottom of the cylinder, and its rotation center coincides with that of the cylinder and the rotating shaft. The main gear is installed at the lower end of the rotating shaft extending from the bottom of the cylinder. The main gear and the gear ring are connected via a gear transmission through the transition gear, and the rotating shaft of the transition gear is fixedly installed on the support plate. A discharge port is provided on the bottom plate of the cylinder. The valve component is located at the bottom of the cylinder and includes a small shaft, a sealing plate, and a small wheel. The small shaft is fixedly installed at the bottom of the cylinder, the sealing plate is rotatably connected to the small shaft, and the small wheel is installed on the lower surface of the sealing plate and rotatably connected to it. The sealing plate corresponds to the discharge port. The support assembly includes a rolling ball, a support plate, and a ball-grooved ring. The ball-grooved ring is fixedly installed on the support plate, corresponding to the ball-grooved ring at the bottom of the cylinder. A rolling ball is placed between the upper and lower ball-grooved rings. An arc-shaped discharge port is provided on the support plate between the ball-grooved ring and the toothed ring, with inclined plates at the two arc ends of the arc-shaped discharge port. The valve assembly cooperates with the support assembly to open and close the discharge port. The valve assembly opens when it rotates above the arc-shaped discharge port and closes at other positions.

[0006] Furthermore, to adapt to large-scale continuous production and improve the uniformity of mixing, the two stirring devices are arranged vertically with the same center of rotation, and their shafts are connected by a coupling.

[0007] Furthermore, to prevent residual particles on the sealing plate from damaging the valve assembly, the axle of the small wheel is movable up and down, and a compression spring is installed on the upper part of the axle, so that the up and down position of the small wheel can be adjusted by the compression spring.

[0008] Furthermore, the sealing plate is stepped, with the upper protrusion corresponding to the discharge port and the lower flat plate cooperating with the bottom plate of the cylinder to form a curved seal, preventing the falling of granular raw materials.

[0009] Furthermore, to improve mixing efficiency, the stirring rods are square-shaped, and there are 2 to 6 rods, preferably four.

[0010] Furthermore, the number of discharge ports should preferably be 2 to 3 evenly distributed.

[0011] Furthermore, for safe production, an outer shell and a cover are respectively provided on the outer side and upper part of the cylinder to enclose the rotating parts.

[0012] The beneficial effects of this utility model are: this utility model realizes stirring and mixing during continuous production, and realizes automatic opening and closing of the valve assembly through the structure. The structure is simple and the manufacturing cost is low. Attached Figure Description

[0021] For the sake of simplicity and cleanliness, many related lines between the bottom of the cylinder and the support plate have been omitted, and only the cross-sectional structural components are retained. The motor drive device, bearing connections, etc., are all existing technologies and will not be described in detail. Example 1

[0022] The structure of the stirring device in this embodiment is shown in the attached figure. Figure 1-4 As shown, the assembly includes a stirring component, a rotating cylinder component, a support component, and a valve component 5. The stirring component is housed within the rotating cylinder component, and the two rotate in opposite directions. When the stirring rod rotates counterclockwise, the cylinder rotates clockwise. The support component is located at the bottom of the cylinder and supports the rotation of the cylinder, as well as controlling the opening and closing of the valve component 5.

[0023] The stirring assembly includes a rotating shaft 12 and stirring rods 2. The stirring rods 2 are fixedly mounted on the rotating shaft 12, evenly distributed around the circumference, and number 2 to 6, as shown in the attached diagram. Figure 2As shown, this embodiment uses four stirring rods. The stirring rods are rectangular; the lower horizontal bar serves as the stirring rod, while the two vertical bars act as a connector and also perform stirring. The upper horizontal bar is fixedly connected to the rotating shaft. The rotating shaft 12 is connected to a motor drive device. When the motor drive device is energized, it drives the rotating shaft and stirring rods to rotate. More stirring rods result in better mixing of the organic fertilizer raw materials, but also increase rotational resistance and motor power. Considering manufacturing and dynamic balance, four stirring rods are recommended.

[0024] The rotating cylinder assembly includes a cylinder 1, a transition gear 6, a main gear 7, and a gear ring 8. The gear ring 8 is fixedly installed at the bottom of the cylinder 1, and the rotation centers of the gear ring 8, cylinder 1, and rotating shaft are aligned. The main gear 7 is installed at the lower end of the rotating shaft extending beyond the bottom of the cylinder, and the main gear 7 is connected to the gear ring 8 via the gear transmission of the transition gear 6. (See attached...) Figure 3 As shown, the rotating shaft drives the main gear 7 to rotate counterclockwise, and the transition gear 6 to rotate clockwise, which in turn drives the gear ring 8 and the cylinder to rotate clockwise, thus achieving the opposite rotation of the stirring rod and the cylinder. A discharge port 13 is provided at the bottom of the cylinder between the gear ring and the ball groove ring, as shown in the attached diagram. Figure 2 As shown. It is advisable to have 2-3 evenly distributed discharge ports 13. One discharge port reduces the efficiency of mixing and material feeding, while three discharge ports increase the need for valve assemblies; two are most suitable. To avoid the formation of dead zones inside the cylinder, the junction of the ring plate and the bottom plate of the cylinder should preferably be a rounded corner.

[0025] The support components include the ball bearing 3, the support plate 4, the ball groove ring 10, etc., as shown in the attached document. Figure 1 and attached Figure 3 As shown. The support plate 4 is horizontal, and the rotating shaft of the transition gear 6 is fixedly installed on the support plate 4. A ball groove ring 10 is fixedly installed on the support plate, and the same ball groove ring 10 is installed at the same position on the bottom of the cylinder. A rolling ball 3 is placed between the upper and lower ball groove rings. In this way, the support plate 4 supports the rotation of the drum through the rolling ball 3 and the ball groove ring 10. An arc-shaped discharge port 9 is provided on the support plate between the ball groove ring and the gear ring. An inclined plate 14 is provided at the two arc ends of the arc-shaped discharge port. The inclined plate cooperates with the valve assembly 5 to realize the opening and closing of the cylinder discharge port 13.

[0026] The structure of valve assembly 5 is shown in the attached figure. Figure 4 As shown, it includes a small shaft 51, a sealing plate 52, and a small wheel 53. The small shaft 51 is fixedly installed at the bottom of the cylinder. The sealing plate 52 is rotatably connected to the small shaft 51. The small wheel 53 is installed on the lower surface of the sealing plate 52 and is rotatably connected to the sealing plate. The sealing plate 52 is used to open and close the discharge port 13. To achieve closure of the discharge port, the sealing plate 52 is stepped. The upper boss of the sealing plate corresponds to the discharge port 13, and the lower flat plate cooperates with the bottom plate of the cylinder. In this way, the discharge port forms a curved seal, so even if the sealing plate is not closed properly, the granular raw material inside the cylinder cannot fall from the discharge port. When the valve assembly 5 is located in the attached... Figure 4When the solid line position is reached, the small wheel 53 of the valve assembly rotates onto the support plate 4, and the sealing plate 52 closes the discharge port. When the valve assembly rotates above the arc-shaped discharge port 9, the valve assembly rotates downwards under its own weight, thus closing the discharge port. Figure 4 At the position indicated by the double-dot line, the discharge port opens, and the raw material inside the cylinder falls into the arc-shaped discharge port 9 by its own weight. As the cylinder rotates, when the small wheel 53 contacts the inclined plate 14, the sealing plate 52 begins to rotate upward to close the discharge port. It should be noted that the installation position of the small shaft is related to the rotation direction of the cylinder. When the cylinder rotates, the inclined plate of the arc-shaped discharge port should contact the small wheel, not the sealing plate.

[0027] For safe production, an outer shell 11 and a cover are added to the outside and top of the cylinder to enclose the rotating parts inside. At the same time, dust removal pipes are installed at the material discharge points, such as the feed inlet and discharge outlet, to avoid dust pollution from material discharge and agitation.

[0028] In this embodiment, the motor drive is activated, and the rotating shaft drives the stirring rod and the cylinder to rotate in opposite directions. The pre-mixed organic fertilizer raw material granules are added through the upper feed inlet. The raw material granules fall into the cylinder and begin to mix evenly under the stirring action of the stirring rod. The cylinder's rotation of the raw material granules and the stirring rod effectively accelerates the stirring rod's speed and enhances the mixing effect. When the valve assembly 5 rotates above the arc-shaped discharge port, the raw material granules fall from the discharge port under the pushing action of the stirring rod. This embodiment has two discharge ports, and the arc of the discharge port is nearly semi-circular, thus achieving essentially continuous feeding of the raw material granules. Example 2

[0029] This embodiment arranges the stirring devices from two embodiments 1 vertically, as shown in the attached figure. Figure 5 As shown. The rotation centers of the upper and lower stirring devices are the same, and the rotating shafts are connected by coupling 15. When the motor drive device is started, the upper and lower stirring devices operate simultaneously.

[0030] The arc-shaped discharge port 9 of the upper mixing device is positioned opposite to the arc-shaped discharge port of the lower mixing device, and the small shaft of the upper and lower valve assembly 5 is installed in the opposite position to the discharge port, ensuring that the inclined plate contacts the small wheel and realizes smooth opening and closing of the discharge port.

[0031] Compared to Example 1, this embodiment adds an extra stirring step, resulting in more uniform raw material particles and improving the uniformity of the mixture. The footprint remains the same, making it suitable for production lines with continuous raw material supply or high operating speeds. Example 3

[0032] This embodiment is merely an improvement on the valve assembly in the above embodiments, as shown in the appendix. Figure 6As shown, a compression spring 54 is installed on the upper part of the axle of the small wheel to adjust the position of the axle; the small wheel rotates when the axle does not rotate. When the sealing plate 52 gradually closes, some raw material particles that have not fallen will remain on the plate, causing the boss of the sealing plate to not fit tightly with the discharge port. Although this will not cause the raw material particles inside the cylinder to fall, it will cause the position of the axle of the small wheel to shift downwards, and the position of the lower wheel will also shift downwards. In severe cases, it will get stuck on the inclined plate of the arc-shaped discharge port, causing damage to the valve assembly. To address this, the axle of the small wheel is designed to be adjustable up and down, and the compression spring 54 is used to press down on the axle. In this way, the axle and the small wheel can be freely adjusted in their vertical position to accommodate the situation where particles remain on the plate of the sealing plate.

[0033] This invention achieves mixing and stirring under continuous feeding and discharging of raw material particles, meeting the requirements of continuous production. The invention utilizes structural features to achieve the opening and closing of the valve assembly, with only one motor drive for rotation. The gears are located in a relatively enclosed space, preventing dust contamination. The structure is simple and the manufacturing cost is low.
