Description

Technical Field

[0001] The invention relates to the technical field of organic fertilizer equipment, and in particular to a raw material mixing device for organic fertilizer fermentation. Background Art

[0002] Adjusting the carbon-nitrogen ratio is a key step in some organic fertilizer fermentation processes. By controlling the ratio of carbon (C) and nitrogen (N) elements in the raw materials, the fermentation process can be optimized, promoting the rapid decomposition of organic matter and the active growth of microorganisms. Carbon sources generally come from organic matter with a high carbon content, such as straw, sawdust, and stalks; while nitrogen sources come from organic matter with a high nitrogen content, such as chicken manure, cow manure, and pig manure. Since different raw materials are decomposed by microorganisms at different rates during the fermentation process, if the raw materials are unevenly distributed, the temperature in some places may be too high, affecting the activity of microorganisms, or the temperature in some places may be too low, slowing the fermentation process. Therefore, in the production process of organic fertilizers, the mixing of raw materials is a crucial link.

[0003] When handling bulk organic fertilizer raw materials, some manufacturers use forklifts to mix the raw materials to facilitate on-site composting and fermentation of the mixed raw materials. However, this method is difficult to ensure the uniformity of raw material mixing. For this reason, some manufacturers use mixing equipment to centrally mix the raw materials to obtain more uniform fermentation raw materials. However, mixing equipment often faces cleaning problems during long-term use, especially when using raw materials such as animal manure, raw material residues are easily accumulated on the surface of the mixing equipment. These accumulations gradually solidify and adhere more firmly over time, increasing the difficulty of equipment maintenance. In the current production process, it is accustomed to cleaning the mixing equipment after the mixing is completed or when the accumulation reaches a certain amount. However, this cleaning method has a lag, and the accumulation is often unable to be discovered and handled in time, especially in the continuous mixing system, where the continuity of the production process makes the cleaning work more complicated. Since the mixing equipment is usually set inside the cabin, some difficult cleaning parts may need to be shut down for disassembly and cleaning, which will extend the production line downtime and affect production efficiency. At present, although some equipment has an automatic cleaning function during the mixing process, most cleaning mechanisms still rely on manual intervention and often cannot work in conjunction with the mixing system.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0037] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] See also Figure 1 to Figure 12 The present application is used to mix the raw materials of organic fertilizer fermentation in the carbon-nitrogen ratio adjustment stage during the organic fertilizer production process, and includes a fixed shell 100, a feeding port 110 is arranged on the top of the fixed shell 100, and the feeding port 110 cooperates with the material conveying equipment 200 on the production line to continuously feed the organic fertilizer raw materials into the fixed shell 100;

[0039] It should be noted that the organic fertilizer raw materials used here are crushed, including nitrogen sources, such as cow dung, chicken dung, pig dung and food waste that can replace them, as well as carbon sources, such as straw, rice straw, sawdust and husks, and also include catalysts that promote the fermentation of these raw materials;

[0040] In this embodiment, the feeding port 110 may include a first feeding port 111 and a second feeding port 112 for feeding the carbon source and the nitrogen source. However, the present application does not impose any specific restrictions on the feeding port 110, which may have a variety of implementation forms, such as providing a funnel (not shown in the figure) at the hopper, or changing the feeding port to other shapes, and in addition Figure 1 In some embodiments of the present application, the first feeding port 111 and the second feeding port 112 may also be formed in other areas of the top of the fixed housing;

[0041] See also Figure 2~Figure 5 , a stirring assembly 120 is arranged in the fixed housing 100, and the stirring assembly 120 is connected to a driving device 300 arranged at a side end of the fixed housing 100, as a preferred embodiment of the present application:

[0042] See also Figure 3~Figure 4 The stirring assembly 120 includes a first stirring member 121 and a second stirring member 122. The first stirring member 121 includes a first rotary arm 1211 and a pair of parallel first stirring rods 1212. The ends of the first stirring rods 1212 are connected to a first connecting member 1213. The first connecting member 1213 is rotatably matched with the first rotary arm 1211. The first rotary arm 1211 is rotatably matched with the fixed housing 100 through a first rotating shaft 1214. The first rotating shaft 1214 is connected to the driving device 300.

[0043] See also Figure 5 The second stirring member 122 includes a second swing arm 1221 and a pair of parallel second stirring rods 1222. The end of the second stirring rod 1222 is connected to a second connecting member 1223. The second connecting member 1223 is rotatably matched with the second swing arm 1221. The second swing arm 1221 is rotatably matched with the fixed housing 100 through a second rotating shaft 1224. A cleaning member 130 is provided between the first stirring rod 1212 and the second stirring rod 1222 in a sliding manner. The cleaning member 130 cooperates with the first stirring rod 1212 and the second stirring rod 1222, so that the driving device 300 can transmit the driving energy transmitted through the rotating shaft to the cleaning member 130 through the stirring rod part.

[0044] Driven by the driving device 300, the first stirring member 121 rotates around the axis of the first rotating shaft 1214 (for example, counterclockwise), forming axial stirring in the axial direction of the fixed shell 100; part of the driving energy of the driving device 300 is transmitted to the cleaning member 130 through the first stirring rod 121, so that the cleaning member 130 slides along the axial direction of the second stirring rod 1222, and transmits its driving energy to the second stirring member 122, so that the second stirring member 122 rotates around the axis of the second rotating shaft 1224, forming radial stirring in a direction perpendicular to the axial direction of the fixed shell 100, and stirring in two directions is helpful to obtain a uniform mixture of fermentation raw materials. At the same time, during the rotation of the first stirring member 121 and the second stirring member 122, the cleaning member 130 automatically moves back and forth on the first stirring rod 1212 and the second stirring rod 1222 to remove the accumulation on the stirring rods, thereby ensuring the long-term stability of the equipment and production.

[0045] In other embodiments of the present application, in addition to inputting driving energy through the first stirring member 121, driving energy can also be input through the second stirring member 122, and the effect is the same or similar to that of the above-mentioned embodiment; in a preferred embodiment of the present application, the first stirring member 121 and the second stirring member 122 can also be separately connected to the driving device 300, and stirring in two directions can be achieved by coordinating the rotational speeds of the first stirring member 121 and the second stirring member 122. It can be understood that although this makes the stirring effect more flexible and adjustable, the two independent driving devices 300 will also increase the cost of the equipment.

[0046] See also Figure 1~Figure 3A discharge port (not shown in the figure) is formed at the bottom of the fixed housing 100, and the discharge port is used to discharge the mixed organic fertilizer raw materials in the fixed housing 100, and cooperate with the material conveying device 200 to convey the mixed organic fertilizer raw materials to the next link. In this embodiment, the discharge port is provided with a discharge valve 140 to better control the discharge state. The discharge valve 140 can be an electric valve, a pneumatic valve or a mechanical valve. This application does not specifically limit it, and it can adopt a discharge device of various structures that can be adopted by personnel in the technical field to which the present invention belongs.

[0047] See also Figure 3~Figure 5 The driving device 300 includes a driving motor 310, a reducer 320 and a control cabinet 330. The driving motor 310 is used to generate driving force, the reducer 320 is used to reduce the speed of the driving motor 310, and the control cabinet 330 is used to monitor and adjust the operation of the driving motor; the reducer 320 is arranged on the outer wall of the fixed housing 100 through a bracket, and the output end of the reducer 320 is coaxially matched with the first rotating shaft 1214. It can be understood that the structure of the driving device 300 above is only used as an example, and the present application does not specifically limit it. Personnel in the technical field to which the present invention belongs can use driving devices of various structures to rotate the first rotating shaft 1214.

[0048] It should be noted that each of the stirring rods (1212, 1222) and the connecting members (1213, 1223) are rotatably matched via bearings, so that the stirring rods (1212, 1222) can rotate during the stirring process. When the cleaning member 130 reciprocates on the stirring rods (1212, 1222), the accumulated materials on the surface of the stirring rods (1212, 1222) can be effectively removed. Due to the rotation of the stirring rods, the cleaning member 130 can cover a wider surface area of ​​the stirring rods (1212, 1222).

[0049] See also Figure 5~Figure 6 The cleaning member 130 is arranged on the inner side of each stirring rod (1212, 1222) in a form of being clamped by the first stirring rod 1212 and the second stirring rod 1222 at the same time, so that the stirring rod transfers part of the driving energy of the driving device 300 to the cleaning member 130 through cooperation with the cleaning member 130; for the transfer process, please refer to Figure 6 , Figure 6Figures A to F are state diagrams of the stirring member when it rotates at different angles, and the arrows in the figures are used to indicate the order of angle changes. L1 in the figure is the axis of the first rotating shaft. Taking the rotation state of the first rotary arm 1211 as an example, Figure B is a state diagram of the first rotary arm 1211 in Figure A after it rotates 60° in the clockwise direction; Figure C is a state diagram of the first rotary arm 1211 in Figure B after it rotates 30° in the clockwise direction; Figure D is a state diagram of the first rotary arm 1211 in Figure C after it rotates 60° in the clockwise direction; Figure E is a state diagram of the first rotary arm 1211 in Figure B after it rotates 15° in the clockwise direction; FIG. D is a state diagram of the first rotary arm 1211 after rotating 60° in the clockwise direction; FIG. F is a state diagram of the first rotary arm 1211 in FIG. E after rotating 60° in the clockwise direction; FIG. F is a state diagram of the first rotary arm 1211 returning to the state shown in FIG. A after continuing to rotate 90° in the clockwise direction; as the stirring member and the first rotating shaft 1214 rotate, the cleaning member 130 slides back and forth on the stirring rod to clean the accumulated matter; the movement trajectory of the cleaning member 130 on the first stirring rod 1212 and the second stirring rod 1222 is shown in FIG. Figure 7 As shown, according to the different rotation directions of the stirring member, there are two sets of motion trajectories, namely the first trajectory R1 and the second trajectory R2, both of which are roughly elliptical; as an example, when the first rotating shaft 1214 is Figure 6 When the cleaning member 130 rotates clockwise in the order of FIG. A to FIG. F, the movement trajectory of the cleaning member 130 is the first trajectory R1, and vice versa, it is the second trajectory R2.

[0050] See also Figure 8 The cleaning member 130 has a support portion 131 in contact with the axis of the outer peripheral surface of the stirring rod (1212, 1222). The support portion 131 is parallel to the axial direction of the corresponding stirring rod and plays a role in supporting and fixing the cleaning member 130. On the surface of the cleaning member 130, the support portion 131 is arranged close to the structural center of the cleaning member 130 to ensure that the cleaning member 130 obtains uniform force when being driven. More specifically, on a cross section perpendicular to the axis of the stirring rod (1212, 1222), the support portion 131 is a notch that matches the outer peripheral surface of the stirring rod. The curvature of the notch is the same as the curvature of the outer peripheral surface of the stirring rod (1212, 1222) to ensure that the support portion 131 can fit tightly against the outer surface of the stirring rod to form a stable contact surface.

[0051] See also Figure 8The cleaning member 130 is provided with a cleaning blade 132 on the outer side of the supporting portion 131. The cleaning blade 132 is arranged along the axial direction of each stirring rod and is used to cut off the fiber raw material entangled on the stirring rod when the cleaning member 130 moves back and forth; the fiber raw material here refers to straw, rice straw and other forage. Since there may be parts that are not completely crushed in the forage, these forages are easily entangled on the stirring rod when the organic fertilizer raw materials are mixed. The forages entangled on the stirring rod are difficult to be removed by the cleaning member. Here, the cleaning blade 132 is provided to remove these entangled forages.

[0052] See also Figure 8 The cleaning blade 132 has a blade seat 1321 and a blade portion 1322. The blade seat 1321 is fastened to the cleaning member 130 by bolts. The blade portion 1322 includes a cutting edge, which is a sharp V-shaped cutting edge for cutting off the fiber raw material wound on the stirring rod. The middle part of the blade portion is hollow, so that during the stirring process, the organic fertilizer raw material can pass through the middle part of the blade portion. This reduces the residue of the organic fertilizer raw material at the blade portion 1322 and reduces the resistance of the blade portion 1322 during the stirring of the device.

[0053] See also Figure 8~Figure 10 , the end surfaces of the first connecting member 1213 and the second connecting member 1223 facing the cleaning member 130 are both provided with protrusions 133, and the protrusions 133 are arranged along the outer periphery of the stirring rod; it can be understood that, since the cleaning member 130 is in a state of sliding on the stirring rod, the grass that is not directly cut by the cleaning blade 132 will be pushed by the cleaning member 130 and moved to the two ends of the stirring rod. As the cleaning member 130 moves back and forth on the stirring rod, these grasses are easily accumulated at the connection between the two sides of the stirring rod and the connecting member, causing these grasses to be entangled with the outer side of the bearing cover 150 of the stirring rod and the connecting member, affecting the rotation performance of the stirring rod;

[0054] The protrusion 133 is designed to prevent the grass from being entangled with the outer side of the bearing cover 150 on the connecting piece; the protrusion 133 can be a symmetrical structure or a Fig.10 The asymmetric structure shown; in an optional embodiment, see Fig.10The structure of the protrusion 133 is block-shaped. Taking the configuration outside the first stirring rod 1212 as an example, the protrusion 133 includes an anti-winding portion 1331 and a guide portion 1332. The anti-winding portion 1331 is matched with the stirring rod gap to break the continuity of the grass 400 on the surface of the first stirring rod 1212 and its bearing cover, so that the grass 400 is not easy to accumulate or form continuous contact points on the surface of the first stirring rod 1212, and helps the grass 400 fall off from the surface of the first stirring rod 1212. The guide portion 1332 is used to make the grass 40 0 slides along the surface of the protrusion 133 away from the first stirring rod 1212; more specifically, the anti-winding portion 1331 forms a ridgeline or edge structure with a certain length along the axial direction of the corresponding stirring rod. Different from a round or smooth structure, the design of the ridgeline or edge structure makes it more difficult for the forage 400 to slide smoothly along the surface of the stirring rod; the guide portion is arranged along the radial direction of the corresponding stirring rod, and guides the forage to roll or slide through a plane or sloped surface; therefore, in some embodiments of the present application, the protrusion 133 can also be as follows Fig.11 The triangle and trapezoid shown can also be used to break the continuity of the grass 400 on the stirring rod and guide the grass 400 to slide.

[0055] See also Figure 8 , Fig. 9 and Fig.12 Taking the first connecting member 1213 as an example, the connecting member is provided with the protrusion 133 at least at the moving path of the cleaning blade 132, and the protrusion 133 is formed with a slit 1333 that matches the blade portion 1322; see Fig.12 The slit 1333 is used to form a supporting state that is convenient for cutting grass. When the grass 400 wrapped around the stirring rod contacts the end surface of the protrusion 133, the slit 1333 will limit the cutting of the grass 400 to a more ideal cutting position due to its shape and depth, so that the cleaning blade 132 can act on the grass 400 more effectively, thereby improving the cutting and cleaning effects of the cleaning blade.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
