Description

Technical Field

[0001] The invention relates to the field of excrement microbial degradation equipment, in particular to a microbial degradation equipment for livestock and poultry excrement treatment. Background Art

[0002] With the rapid development of scale and intensiveness of livestock and poultry breeding industry, it has played an important role in ensuring the supply of livestock and poultry products in urban and rural areas, but it is also accompanied by problems such as the effective treatment and utilization of livestock and poultry manure.

[0003] At present, the most common method for treating livestock and poultry manure is to first separate the dry and wet manure, then concentrate the dry manure in a fermentation tank and mix it with bedding, then add microbial fermentation agents, and wait for the fermentation to be completed before returning it to the field for use. However, before being collected, the manure will be repeatedly trampled by livestock and poultry and become compacted, resulting in poor air permeability, which cannot provide a good growth environment for microorganisms, and easily lead to problems such as long fermentation time and poor fermentation effect.

[0004] In view of the above problems, some solutions have been proposed in the prior art, such as a microbial degradation device for livestock and poultry manure with publication number CN115677389A. The prior art turns and raks the manure with a mixing mechanism to fully mix the manure with the bedding, and at the same time can loosen the compacted manure, thereby increasing the ventilation volume and providing a suitable growth environment for the microorganisms. However, the four sides of the fermentation tank are usually right-angled sides, and the stirring range of the mixing mechanism in the prior art is usually circular, which makes it impossible to effectively turn over the manure at the edge of the fermentation tank, resulting in poor fermentation effect at the edge of the fermentation tank. At the same time, since the microbial fermentation agent is sprayed on the upper layer of the manure pile, short-term turning and stirring can easily lead to uneven mixing of the fermentation agent and the manure, resulting in inconsistent fermentation time and effect in different areas, and the area at the bottom of the edge of the fermentation tank is difficult to mix with the fermentation agent, and long-term turning and stirring will reduce production efficiency.

[0005] Therefore, a microbial degradation device for treating livestock and poultry manure is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a microbial degradation device for treating livestock and poultry manure, which solves the problem that traditional equipment can only cover a circular range, resulting in dead corners in stirring and difficulty in evenly mixing the microbial fermentation agent and manure. Through the principle of Leno's triangle, the stirring range is formed into a square that can fit the edge of the fermentation tank, and the microbial fermentation agent is continuously injected during the stirring process, which improves the stirring effect and makes the distribution of the microbial fermentation agent more uniform, thereby improving the degradation efficiency of manure.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A microbial degradation device for treating livestock and poultry manure is used in conjunction with a fermentation tank, comprising a movable base, a fixed frame, a movable frame and a driving mechanism, and also comprising a driving block, a connecting block, a triangular plate, a feed port, a stirring sheet, a discharge port and a shielding component, wherein the driving block is connected to the lower side of the driving mechanism, the connecting block is connected to the driving block, the triangular plate is connected to the connecting block, the connection point between the driving block and the connecting block is not coaxial with the connection point between the connecting block and the triangular plate, the triangular plate is a Leno triangle, the feed port is arranged at the upper end of the triangular plate, the three stirring sheets are respectively connected to the bottom of the three sides of the triangular plate, the discharge port is arranged on the inner surface of the stirring sheet, the discharge port is connected to the feed port, the shielding component is connected to the stirring sheet and covers the surface of the discharge port, the driving mechanism controls the rotation of the stirring sheet through the triangular plate, and at the same time, the resistance of the manure pushes the shielding component to move and exposes the discharge port, and the discharge port continuously flows out the microbial fermentation agent as the stirring sheet moves.

[0009] In the process of making fertilizer from manure, the energy in the manure needs to be consumed to avoid root burn when it is used as fertilizer in the future. Therefore, it is necessary to mix microbial fermentation agents into the manure when it is composted and fermented, so as to consume the energy in the manure through the massive reproduction of microorganisms. In addition to energy, the reproduction of microorganisms also requires a large amount of oxygen. Therefore, it is necessary to ensure that there is sufficient air circulation in the manure. However, the manure is often repeatedly trampled by livestock and poultry before collection to become compacted, resulting in poor air permeability, which in turn affects the massive reproduction of microorganisms. Therefore, in the existing scheme, materials such as straw are usually evenly mixed into the manure. These relatively loose materials will bridge each other, thereby ensuring that the microorganisms have enough oxygen to reproduce. However, since the stirring range of the existing stirring equipment is usually circular and the effective stirring of the stirring blades is There are gaps between the mixing ranges, so the mixing of manure and straw is not uniform, which in turn affects the uniformity of ventilation, and it is not easy to ensure the uniformity of microbial reproduction in manure, resulting in different fermentation effects in different areas. Through the above scheme, the triangular plate is set as a Leno triangle, and then corresponding stirring pieces are set on the lower sides of the three edges of the triangular plate. The stirring range of the stirring piece is formed into a square range through the principle of Leno triangle, which can be fitted with the edge of the fermentation tank to ensure that the manure in the fermentation tank can be stirred without dead ends, so that the manure and straw and other filling materials can be fully mixed, thereby ensuring the amount of air entering the manure; and while the stirring piece is stirring, the microbial fermentation agent is continuously discharged from the discharge port, so that the microorganisms can be evenly mixed into the manure, thereby ensuring the fermentation effect of manure in different areas.

[0010] Preferably, the side length of the motion coverage range of the triangle plate is a, the distance between the motion coverage ranges of two triangle plates is b, and a>b.

[0011] Through the above scheme, part of the coverage area between two adjacent triangular plates can overlap with each other, thereby avoiding the problem that the area between the two sets of stirring blades in traditional equipment cannot be stirred, and further ensuring the stirring effect of manure.

[0012] Preferably, the inner side of the stirring piece is a straight surface, the outer circle of the stirring piece is an arc surface with the same shape as the edge of the triangular plate, and the thickness of the stirring piece gradually increases from front to back in the moving direction.

[0013] Through the above scheme, the outer circle of the stirring plate is set to the same arc surface as the triangular plate, which can ensure that the shape of the active coverage range of the stirring plate is square, so that the stirring range can match the shape of the fermentation tank; the thickness change of the stirring plate makes it have less resistance when moving in the feces.

[0014] Preferably, a guide groove is arranged on the arc surface of the outer ring of the stirring blade, and the guide groove is an arc groove. The guide groove is arranged to be gradually inclined upward from front to back in its moving direction. A convex strip is arranged in the guide groove, and the convex strip is arranged along the opening direction of the guide groove.

[0015] Through the above scheme, during the process of the stirring blade rotating and inserting into the feces, the guide groove can guide the flow direction of the feces and reduce the resistance when the stirring blade is rotating and inserted; the setting of the convex strips can disperse the feces flowing through, making it loose, and then increase the amount of air entering, thereby providing sufficient oxygen for the reproduction of microorganisms, thereby ensuring the fermentation effect of the feces.

[0016] Preferably, the discharge port is arranged on a straight surface inside the stirring blade, and the discharge port is inclined in the opposite direction to the moving direction of the stirring blade.

[0017] Through the above scheme, the microbial fermentation agent is located in the discharge port. When the stirring blade moves forward, the fermentation agent will be separated from the stirring blade because it cannot keep up with the speed of the stirring blade, and will continuously flow out through the discharge port and then mix with the feces. Moreover, since the stirring blade continuously moves in the front and rear directions during the rotation process, the microbial fermentation agent can be fully and evenly placed in various areas of the fermentation tank, thereby ensuring the fermentation effect of the feces.

[0018] Preferably, a baffle is provided on the side of the stirring blade away from the shielding component, the baffle is inclined, the slope of the baffle is the same as the slope of the discharge port, and a plurality of rows of protrusions are provided in the vertical direction on the side of the baffle close to the stirring blade.

[0019] Through the above scheme, the baffle is arranged at the front end of the moving direction of the discharge port, thereby preventing feces from entering the discharge port during the movement, and ensuring that the fermentation agent can flow out of the discharge port normally.

[0020] Preferably, a plurality of mounting grooves are provided in the stirring plate, and the shielding assembly includes a shielding plate, a connecting plate, a card plate and a reset spring, the connecting plate is connected to the mounting groove, the shielding plate is connected to the connecting plate, the shielding plate is "L"-shaped, the card plate is connected to the connecting plate, the cross-sectional surface area of ​​the card plate is larger than the cross-sectional surface area of ​​the connecting plate, the reset spring is provided inside the stirring plate, and the two ends of the reset spring are respectively connected to the card plate and the stirring plate.

[0021] Through the above scheme, in a static state, that is, when not inserted into the manure for stirring, the baffle is in a state of covering the discharge port, thereby preventing the fermentation agent from flowing out of the discharge port; when in the stirring stage, the stirring blade continues to move in the moving direction, and the baffle will move in the opposite direction of the moving direction of the stirring blade under the action of the resistance of the manure, and then remain relatively still with the stirring blade under the action of the card plate. At this time, the movement of the baffle exposes the discharge port, and then the fermentation agent continues to flow out during the movement of the stirring blade.

[0022] Preferably, the shield is provided with an inclined plate at the front end in the moving direction, and the slope of the inclined plate is the same as the slope of the baffle.

[0023] Through the above scheme, when in a stationary state, the inclined plate covers the discharge port and maintains a nearly close fit with the baffle; when in the stirring stage, the inclined plate can reduce the resistance of its movement in the feces and sewage. At the same time, since the slope of the discharge port is the same as that of the inclined plate, the fermentation agent flowing out of the discharge port can flow out along the inclined plate and is more easily mixed with the feces and sewage.

[0024] Preferably, the inclined plate is provided with multiple rows of sawtooth strips in its inclined direction, the sawtooth strips include multiple teeth, the teeth and the protrusions are staggered in the vertical direction, and the thickness of the protrusions is the same as the shortest vertical distance between every two teeth on the sawtooth strip.

[0025] Through the above scheme, the serrated bar can stir the feces and sewage as it moves in the feces and sewage, thereby making the compressed feces and sewage looser and increasing the amount of air that can pass through it; and because the spacing between the teeth is small, it is more troublesome to clean the feces and sewage remaining between the teeth after the stirring is completed. Therefore, by providing a protrusion structure on the baffle, after the baffle is reset at rest, the teeth and the protrusions are interlaced and inserted into each other's gaps, and then the feces and sewage remaining between the teeth are cleaned up by the protrusions.

[0026] Preferably, a fixing rod is connected to the inner side of the stirring blade, and the fixing rods on the lower sides of the three stirring blades are connected to each other.

[0027] Through the above scheme, the free ends of the three stirring blades are connected to each other through the fixing rod, thereby avoiding the stress concentration at the connection between the stirring blade and the triangular plate during operation, which may cause damage to the components. It plays a role in balancing the stress and can also improve the stability of the stirring blade.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention solves the problem that the traditional stirring method has a stirring dead angle, resulting in poor stirring effect and thus affecting the air intake, as well as the uneven mixing and distribution of feces and microbial fermentation agents. Through the principle of Leno's triangle, the three stirring blades cooperate with each other to form a square stirring range, and the stirring ranges formed by multiple groups of stirring blades will overlap, which can not only ensure that the feces are stirred without dead angles, but also improve the stirring effect; while the stirring blades rotate and move forward, the microbial fermentation agent continuously flows out of the discharge port, and is fully mixed with the feces as the stirring blades move, ensuring the uniformity of the mixing and distribution of the microbial fermentation agent and feces.

[0030] 2. By setting a stirring blade and a shielding component, when the stirring blade is in a stationary state, the shield will cover the discharge port to prevent the microbial fermentation agent from flowing out of the discharge port; when the stirring blade is in a moving state, the shield will move in the opposite direction of the moving direction of the stirring blade under the action of the resistance of feces and sewage, and the discharge port will be exposed at this time, and then the fermentation agent will continuously flow out during the movement of the stirring blade. The outflowing fermentation agent is fully mixed with feces and sewage as the stirring blade continues to stir and move forward, and can be evenly distributed in various areas of the fermentation tank, so that the fermentation effect of feces and sewage at different positions of the fermentation tank remains consistent, thereby ensuring the fermentation effect.

[0031] 3. By setting the sawtooth bar and the protrusion, the sawtooth bar can disperse the compressed feces and dirt, thereby increasing the amount of air that can enter, ensuring the amount of oxygen required for microbial reproduction; when the stirring is completed, the reset spring drives the baffle to reset, and then the inclined plate is close to the baffle. Since the feces and dirt remaining between each tooth on the sawtooth bar are inconvenient to clean, when the inclined plate is close to the baffle, the teeth and the protrusions are staggered and inserted into each other's gaps, and then the feces and dirt remaining between the teeth are pushed out through the protrusions, thereby achieving the effect of cleaning the feces and dirt remaining between the teeth.

DETAILED DESCRIPTION

[0041] 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 creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 8 The present invention provides a microbial degradation device for livestock and poultry manure treatment, and the technical solution is as follows:

[0043] For details, please refer to Figure 1 and Figure 2, a microbial degradation device for livestock and poultry manure treatment, used in conjunction with the fermentation tank 1. The fermentation tank 1 is of a square structure with an opening at its top. It includes a mobile base 2, a fixed frame 3, a movable frame 4, and a driving mechanism 5. The mobile base 2, the fixed frame 3, and the movable frame 4 form an inverted U shape. The fixed frame 3 and the movable frame 4 are connected to the mobile base 2 through electric telescopic rods and can be lifted relative to the mobile base 2, thereby changing the height of the device. Moreover, the movable frame 4 is connected to the fixed frame 3 through an electric telescopic rod, enabling the movable frame 4 to move horizontally relative to the fixed frame 3. The driving mechanism 5 is connected to the lower side of the fixed frame 3. There is a motor inside the driving mechanism 5. It also includes a driving block 6, a connecting block 7, a triangular plate 8, a feed inlet 9, stirring blades 10, a discharge outlet 11, and a shielding component 12. The driving block 6 is connected to the lower side of the driving mechanism 5 and is driven by the motor inside the driving mechanism 5 to achieve rotation. The connecting block 7 is rotatably connected to the driving block 6, and the triangular plate 8 is rotatably connected to the connecting block 7. The connection point between the driving block 6 and the connecting block 7 is not coaxial with the connection point between the connecting block 7 and the triangular plate 8. The triangular plate 8 is a Reuleaux triangle, which can make the movement range of the triangular plate 8 form a square range, and then can fit with the edge of the fermentation tank 1, ensuring that the manure in the fermentation tank 1 can be stirred without dead corners, so that the manure and filling materials such as straw can be fully mixed, and further ensuring the air intake inside the manure;

[0044] The feed inlet 9 is arranged on the upper side of the triangular plate 8. There is a cavity inside the triangular plate 8 that can accommodate the microbial fermentation agent. The discharge outlet 11 is arranged on the inner surface of the stirring blade 10. The discharge outlet 11 is communicated with the feed inlet 9. The shielding component 12 is connected to the stirring blade 10 and covers the surface of the discharge outlet 11. While the stirring blade 10 is stirring, the microbial fermentation agent is continuously discharged from the discharge outlet 11, enabling the microorganisms to be evenly mixed into the manure, ensuring the fermentation effect of the manure in different areas;

[0045] The three stirring blades 10 are respectively connected to the bottoms of the three sides of the triangular plate 8. The fixed rods 18 are connected to the inner bottoms of the stirring blades 10. The fixed rods 18 on the lower sides of the three stirring blades 10 are connected to each other, thereby avoiding the situation that the stress concentration at the connection between the stirring blade 10 and the triangular plate 8 causes component damage during operation, playing a role in balancing stress and also improving the stability of the stirring blade 10.

[0046] As an implementation mode of the present invention, refer to Figure 2 and Figure 3The side length of the movement coverage range of the triangular plate 8 is a, and the distance between the movement coverage ranges of the two triangular plates 8 is b, and a>b, so that the coverage ranges of the two adjacent triangular plates 8 partially overlap, avoiding dead corners in stirring and ensuring the stirring effect of the feces; the inner side of the stirring plate 10 is a straight surface, and the outer circle of the stirring plate 10 is an arc surface with the same shape as the edge of the triangular plate 8. The thickness of the stirring plate 10 gradually increases from front to back in its moving direction, so that it has less resistance when moving in the feces.

[0047] As an embodiment of the present invention, refer to Figure 4 A guide groove 13 is arranged on the arc surface of the outer ring of the stirring blade 10. The guide groove 13 is an arc groove. The guide groove 13 is gradually inclined upward from front to back in its moving direction. When the stirring blade 10 is inserted into the feces, it can guide the flow direction of the feces and reduce the movement resistance. A convex strip 14 is arranged in the guide groove 13. The convex strip 14 is arranged along the radial direction of the guide groove 13. When rotating, the convex strip 14 can stir the feces and sewage flowing through, and can crush the filling materials such as straw, so that the ability to bridge each other is stronger, making the space loose, thereby increasing the amount of air intake, providing sufficient oxygen for the reproduction of microorganisms, and thus ensuring the fermentation effect of feces and sewage.

[0048] As an embodiment of the present invention, refer to Figure 5 and Figure 6 The discharge port 11 is arranged on the straight surface of the inner side of the stirring blade 10, and the discharge port 11 is inclined in the opposite direction of the moving direction of the stirring blade 10. When the stirring blade 10 moves forward, the fermentation agent will be thrown away by the stirring blade 10 and separated from the stirring blade 10, and continuously flows out through the discharge port 11, and then mixed with the feces and sewage. Moreover, since the stirring blade 10 continuously moves along the front and rear directions during the rotation process, the microbial fermentation agent can be fully and evenly placed in various areas of the fermentation tank 1, thereby ensuring the fermentation effect of the feces and sewage. A baffle 15 is arranged at the front end of the discharge port 11, and the baffle 15 is also inclined, and the inclination direction and slope of the baffle 15 are the same as those of the discharge port 11, which can avoid the feces and sewage from entering the discharge port 11 during the movement, thereby ensuring that the discharge port 11 can normally flow out the fermentation agent.

[0049] As an embodiment of the present invention, refer to Figure 7 and Figure 8The stirring blade 10 is provided with a plurality of mounting grooves 17, wherein the mounting grooves 17 include square grooves and round hole grooves for accommodating the shielding assembly 12, wherein the shielding assembly 12 includes a shielding plate 1201, a connecting plate 1202, a card plate 1203 and a reset spring 1204, wherein the shielding plate 1201 is in an "L" shape so that it can be connected to the corner of the stirring blade 10, the connecting plate 1202 is connected to the shielding plate 1201, the card plate 1203 is connected to the connecting plate 1202, the cross-sectional surface area of ​​the card plate 1203 is larger than the cross-sectional surface area of ​​the connecting plate 1202, and the reset spring 1204 is arranged inside the stirring blade 10, and the two ends of the reset spring 1204 are respectively connected to the card plate 1203 is connected to the stirring blade 10. When stirring, the shield plate 1201 moves in the opposite direction of the moving direction of the stirring blade 10 under the action of the resistance of feces and dirt, so that the discharge port 11 is exposed, and the fermentation agent continuously flows out during the movement of the stirring blade 10; the shield plate 1201 is provided with an inclined plate 1205 at the front end of the moving direction, and the slope of the inclined plate 1205 is the same as the slope of the baffle 15. During stirring, the inclined plate 1205 can reduce the resistance of its movement in the feces and dirt. At the same time, since the slope of the discharge port 11 is also the same as that of the inclined plate 1205, the fermentation agent flowing out of the discharge port 11 can flow out along the inclined plate 1205 and is more easily mixed with the feces and dirt.

[0050] As an embodiment of the present invention, refer to Figure 6 and Figure 8 , a side of the baffle 15 close to the stirring piece 10 is provided with multiple rows of protrusions 16 in the vertical direction, and a certain distance is set between each row of protrusions 16; the inclined plate 1205 is provided with multiple rows of sawtooth strips 1206 in its inclined direction, and the sawtooth strips 1206 can stir the feces and sewage when it moves in the feces and sewage, thereby making the compressed feces and sewage looser and increasing the amount of air that can pass into it. The teeth 1207 on the sawtooth strips 1206 are staggered with the protrusions 16 in the vertical direction, and the thickness of the protrusions 16 is the same as the shortest distance between every two teeth 1207 on the sawtooth strips 1206. When the teeth 1207 and the protrusions 16 approach each other, the teeth 1207 and the protrusions 16 are staggered and inserted into each other's gaps, and then the feces and sewage remaining between the teeth 1207 are cleaned up by the protrusions 16.

[0051] The specific working principle is as follows: in the preparation stage of the work, firstly, a sufficient amount of microbial fermentation agent is injected into the device from the feed port 9, at which time the microbial fermentation agent will fill the cavity in the triangular plate 8 and be blocked at the discharge port 11 by the shielding component 12;

[0052] First, the fixed frame 3 and the movable frame 4 are lifted to a suitable height by controlling the electric telescopic rod between the fixed frame 3 and the movable frame 4 and the movable base 2, and then moved to a suitable position by the movable base 2, and then the motor in the driving mechanism 5 controls the triangular plate 8 to rotate, and at the same time, the electric telescopic rod controls the fixed frame 3 and the movable frame 4 to move downward, and then the multiple sets of stirring blades 10 are rotated and inserted into the feces.

[0053] During the mobile operation of the equipment, first, in a fixed area, the rotation of the triangular plate 8 drives the three stirring blades 10 to move continuously and form a square stirring coverage range. Since the fermentation tank 1 is usually a square structure, the stirring range of the equipment can stir the feces in the fermentation tank 1 without dead angles;

[0054] When the equipment is working normally, it will reciprocate in the front and back directions of the fermentation tank 1, and then fully stir the feces and sewage in the fermentation tank 1. In this process, it is necessary to add microbial fermentation agents into the feces and sewage, and make them fully and evenly mixed with the feces and sewage. Specifically, the stirring blade 10 continues to move forward during the rotation. At this time, under the action of the resistance of the feces and sewage, the shield 1201 will move in the opposite direction of the moving direction of the stirring blade 10, and then remain relatively still with the stirring blade 10 under the cooperation of the clamping plate 1203 and the mounting groove 17. At this time, the outlet of the discharge port 11 is opened, and because the stirring blade 10 is constantly moving, the fermentation agent will be separated from the stirring blade 10 because it cannot keep up with the rotation speed of the stirring blade 10, and will continue to flow out from the discharge port 11, and then mix with the feces and sewage. In order to prevent the feces and sewage from flowing into the discharge port 11, since the stirring blade 10 rotates continuously, the feces and sewage at the front end of the discharge port 11 can be blocked. Therefore, a baffle 15 is provided at the front side of the discharge port 11 to prevent the feces and sewage from entering the discharge port 11 during the movement, so as to ensure that the fermentation agent can flow out of the discharge port 11 normally; as the triangular plate 8 continues to move forward, the fermentation agent will also be evenly distributed in various areas of the fermentation tank 1, and will be fully mixed with the feces and sewage as the stirring blade 10 stirs.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
