Abstract
Description
Technical Field
[0001] This utility model relates to the field of poultry egg incubation equipment, and in particular to a poultry egg incubator with an eccentric column fine adjustment mechanism. Background Technology
[0002] Incubators primarily simulate the natural incubation environment, controlling temperature, humidity, and ventilation to allow embryos to develop normally. Small poultry egg incubators typically include a housing with a lid and base, a heating and humidification system, a control system, a transmission mechanism, and an alarm system. The heating system mainly consists of heating wires. Existing incubators use heating wires directly fixed to the lid. Over time, the heating wires become loose and deformed. Furthermore, the tightening process cannot be completed in one go during production and installation, leading to loose and uneven distribution of the heating wires. The thermal conductivity of metal heat dissipation wires is related to tension. When taut, the molecular spacing of the material is closer, increasing the heat transfer rate by about 15%-20%. Tight heat dissipation wires reduce heat retention caused by loose wires, allowing heat to be evenly conducted to the incubator space. Loose heat dissipation wires sag due to gravity, causing excessively high temperatures at the bottom and poor temperature control at the top. Heat dissipation wires expand during heating. If installed too loosely, they may sag under their own weight at high temperatures, contacting the egg tray or other components, causing localized overheating or even fire risks and embryo death. Loose heating wires are also prone to metal fatigue due to vibration or temperature changes, shortening their service life. Utility Model Content

[0004] This utility model achieves the above-mentioned objective through the following technical solution: an egg incubator with an eccentric column fine-tuning mechanism, comprising a cover and a base, wherein an accelerated evaporation mechanism is fixedly connected to the cover, the accelerated evaporation mechanism comprising a heating wire assembly, wherein the heating wire of the heating wire assembly is fixedly installed on the inner side of the cover through an eccentric column, the eccentric column passing through mounting holes on both ends, the eccentric column being fixedly installed to the cover through the mounting holes by a fixing member, the central axis of the mounting holes not coinciding with the central axis of the eccentric column, a wire-receiving groove being provided on the outer surface of the eccentric column, the wire-receiving groove being the concave surface of the eccentric column, and a single heating wire of the heating wire assembly being wound in the wire-receiving groove.
[0005] Preferably, a clamping groove is provided on the convex surface of the outer surface of the eccentric column, excluding the concave surface, parallel to the central axis of the eccentric column, to cooperate with a clamping fixture for tightening and loosening the eccentric column.
[0006] Preferably, there are four eccentric pillars, which are set at the four vertices of a quadrilateral, and the heating wires of the heating wire group are evenly distributed around the eccentric pillars to form a quadrilateral.
[0007] Preferably, the eccentric column is cylindrical, and three annular grooves are uniformly arranged on the cylindrical surface of the eccentric column around its central axis.
[0008] Preferably, the outer surface of the eccentric column is corrugated, and the eccentric column is installed at the lower end of the cover after passing through the mounting hole with a fastening screw.

[0014] Compared with the prior art, the beneficial effects obtained by this utility model are:
[0015] This utility model discloses an egg incubator with an eccentric column fine-tuning mechanism, including a cover and a base. An accelerated evaporation mechanism is fixedly connected to the cover. The accelerated evaporation mechanism includes a heating wire assembly. The heating wires of the heating wire assembly are fixedly installed on the inner side of the cover via an eccentric column. The eccentric column passes through mounting holes on both ends. The eccentric column is fixedly installed to the cover via a fixing member passing through the mounting holes. The central axis of the mounting holes does not coincide with the central axis of the eccentric column. A wire-receiving groove is provided on the outer surface of the eccentric column, and the wire-receiving groove is the concave surface of the eccentric column. A single heating wire of the heating wire assembly is wound within the wire-receiving groove. By fixing the eccentric column at the apex of the overall shape of the wire assembly, and with the heating wire wound in the wire-receiving groove, the effective length of the winding path is changed during rotation, utilizing the geometric structure of the eccentric column's axis deviating from the center, thereby achieving tension adjustment. Its core principle can be divided into two parts: the relationship between the eccentricity and the path length. The eccentricity of the eccentric column determines the change in distance from the winding point to the center of rotation. When the eccentric column rotates, the position of the winding point varies within the range of the column radius ± eccentricity. Multiple eccentric columns are arranged at a certain angle (such as at the vertices of a square), and tension is uniformized through synchronous rotation. The small displacements of each eccentric column are superimposed to form a cumulative tension change (i.e., the total tension change is the vector sum of the displacements of each column). During initial production and installation, the eccentric column is rotated to the direction of minimum eccentricity, resulting in the shortest winding path, which facilitates initial installation and subsequent tension adjustment. This utility model discloses a poultry egg incubator with an eccentric column fine-tuning mechanism. It adopts an eccentric column combined tensioning winding system to achieve high-precision, dynamically adjustable tension control. It solves the technical problems of existing poultry egg incubators, such as low heat conduction efficiency due to slack and uneven distribution of heating wires, the shortened service life of slack heating wires due to vibration or temperature changes, and the fire and embryo mortality risks associated with slack heating. It has the beneficial effects of improving heat transfer speed, reducing the risk of embryo mortality during incubation, and extending the service life of heating wires. Attached Figure Description

However, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Example 1
[0026] Please see Figures 1 to 5An egg incubator with an eccentric column fine-tuning mechanism includes an upper cover 1, a middle cover 2, a transmission mechanism 3, an egg-turning tray 4, a base 5, and a water replenishment mechanism 6. The upper cover 1 and the middle cover 2 are assembled and cooperated through a quick-connect and release mechanism. The upper cover 1 integrates a microcomputer control system 11 and an accelerated evaporation mechanism 12. The accelerated evaporation mechanism 12 includes a heating wire assembly 121 and a fan 122. The heating wire assembly 121 is wound around four eccentric columns 7, which are located at the vertices of a quadrilateral. The tension of the heating wires in the heating wire assembly 121 is finely adjusted through the eccentric columns 7. The eccentric columns 7 are circular. The eccentric column 7 is cylindrical and has mounting through holes 72 penetrating both ends. The central axis of the mounting through holes 72 does not coincide with the axis of the eccentric column 7. Three annular wire grooves 71 are evenly arranged around the cylindrical surface on the cylindrical surface of the eccentric column 7. The heating wire of the heating wire group 121 is wound into the wire groove 71. The outer surface of the eccentric column 7 is corrugated. The eccentric column 7 is installed at the lower end of the upper cover 1 after passing through the mounting through holes 72 with fastening screws. The corrugated outer surface of the eccentric column 7 has a clamping groove 73, which cooperates with the clamping fixture to tighten or loosen the eccentric column 7.
[0027] The upper cover 1 is provided with a limiting protrusion, and the middle cover 2 is provided with a limiting groove. The limiting protrusion has a buckle extending to the center of the upper cover, and the limiting groove has a track protrusion extending to the outside of the middle cover. The track protrusion of the limiting groove has a notch. The buckle of the limiting protrusion is inserted into the notch and rotated. The track protrusion of the limiting groove and the buckle of the limiting protrusion cooperate to close the upper cover 1 and the middle cover 2. When it is necessary to open the upper cover 1, the buckle is rotated to the position corresponding to the notch to open the upper cover 1.
[0028] The microcomputer control system 11 is connected to the accelerated evaporation mechanism 12 via communication and electrical connection to control the air volume and temperature. A motor is mounted on the upper cover 1, with one end of the motor's rotating shaft connected to a first transmission component. The microcomputer control system 11 controls the start and stop of the motor. The middle cover 2 has a receiving cavity 21 with ventilation holes on its wall. After the upper cover 1 and the middle cover 2 are fastened together, the accelerated evaporation mechanism 12 is housed within the receiving cavity 21. A second transmission component is attached to the lower part of the receiving cavity 21. The first and second transmission components form a transmission mechanism 3. The rotation of the motor drives the first transmission component, which is a pinion gear (i.e., a drive gear). The teeth of the first transmission component mesh with the teeth of the second transmission component. The middle part of the second transmission component is the main body, with ventilation holes evenly distributed on it. The lower part of the second transmission component is a first connecting part, which includes an insertion protrusion.
[0029] The egg-turning tray 4 includes a movable part 41 and a support part 42. The movable part 41 has a limiting ring adapted to the size of the eggs. A second connecting part is provided on the central axis of the movable part 41. The support part 42 is located below the movable part 41 and is used to support the eggs in case they fall. The support part 42 has evenly distributed through holes to facilitate the evaporation of moisture from the base 5 to the incubation area. A limiting post is provided on the central axis of the support part 42. The second connecting part is hollow and fitted onto the limiting post. The second connecting part includes an insertion groove. The first connecting part and the second connecting part cooperate with the interlocking structure of the insertion protrusion and the insertion groove to realize the rotation transmission of the movable part 41 of the egg-turning tray 4 driven by the second transmission component. For easy insertion, the size of the insertion groove is larger than the size of the insertion protrusion. Thus, the microcomputer control system 11 controls the rotation of the motor, and the first transmission component, the second transmission component, and the overall transmission mechanism of the egg-turning tray 4 are completed for the egg-turning action during the egg incubation process.
[0030] The middle cover 2 and the base 5 are connected by a concave-convex structure. Specifically, the lower edge of the middle cover 2 has a protrusion slightly recessed into the outer surface of the outer shell, and the upper edge of the base 5 has a guide rail slightly extended outwards from the outer surface of the outer shell. The protrusion is inserted into the guide rail to achieve the connection between the middle cover 2 and the base 5. The internal cavity of the base 5 has a water storage area, including a first water storage area and a second water storage area. The evaporation areas of the first and second water storage areas are different. The first and second water storage areas form a ring shape. A water-separating plate is provided between the second and third water storage areas. The surface area of the first water storage area is smaller than that of the second water storage area. An adjustable air inlet 22 is provided on the shell of the middle cover 2. The adjustable air inlet 22 allows external air to enter the incubator, thereby controlling the air flow inside the incubator. The size of the evaporation area meets the different humidity requirements of the poultry egg incubation stage. A water passage is provided on the outer shell of the base 5. The water passage is connected to the water supply bottle 61 through a water supply adapter 62. Based on the principle of communicating vessels and the principle of liquid column pressure balance, it is used to replenish the water in the water storage area of the base 5 in a timely manner.
[0031] Example 2
[0032] Please see Figures 1 to 3 and Figure 6An egg incubator with a rotating drive mechanism includes an upper cover 1, a middle cover 2, a transmission mechanism 3, an egg-turning tray 4, a base 5, and a water replenishment mechanism 6. A microcomputer control system 11 is integrated on the upper cover 1. The microcomputer control system 11 is connected to the transmission mechanism 3 and an accelerated evaporation mechanism 12 via communication and electrical connection. The accelerated evaporation mechanism 12 includes a heating wire assembly 121 and a fan 122. The heating wire assembly 121 is wound around eccentric pillars 7, with four eccentric pillars 7 located at the vertices of a quadrilateral. Heating of the heating wire assembly 121 is achieved through the eccentric pillars 7. The tension of the wire is finely adjusted. The eccentric column 7 is cylindrical and has mounting through holes 72 penetrating both ends. The central axis of the mounting through holes 72 does not coincide with the axis of the eccentric column 7. Three annular wire grooves 71 are evenly arranged around the cylindrical surface of the eccentric column 7. The heating wire of the heating wire group 121 is wound into the wire groove 71. The outer surface of the eccentric column 7 is corrugated. The corrugated outer surface of the eccentric column 7 has a clamping groove 73 on the protrusion, which cooperates with the clamping fixture to perform the tensioning operation of the eccentric column 7.
[0033] The mounting through hole 72 of the eccentric column 7 is fitted onto the limiting fixing column above the fixing bracket 123 and tightened by a knob assembly. The fixing bracket 123 is fixedly installed on the upper cover 1 by fastening screws. The fan 122 is fixedly installed above the ventilation channel of the fixing bracket 123. A filter screen is fixedly installed below the ventilation channel opposite to the position of the fan 122. The filter screen is used to prevent eggshell fragments, egg liquid residue, or excrement generated during incubation from entering the fan 122, causing the heat dissipation system to fail. The upper cover 1 and the middle cover 2 are connected and released by a quick-connect and release mechanism. The structure enables quick disassembly or direct fixed assembly. The quick connection and release mechanism includes, but is not limited to, a tongue-and-groove joint structure and a snap-fit assembly structure. The lower end of the middle cover 2 and the upper part of the base 5 are engaged through a tongue-and-groove joint. That is, the lower edge of the middle cover 2 has a protrusion that is slightly recessed into the outer surface of the outer shell, and the upper edge of the base 5 has a guide rail that is slightly extended outward from the outer surface of the outer shell. The protrusion is inserted into the guide rail to achieve the engagement between the middle cover 2 and the base 5. The base 5 is provided with a water channel on its outside, and the water channel is connected to the water storage bottle 61 through a water supply adapter 62.
[0034] The transmission mechanism 3 includes a motor, a rotating wheel, and an egg-turning tray 4. The motor is fixedly installed in a mounting groove protruding from the main body on the side of the fixed bracket 123. The lower end of the motor extends out of the rotating shaft. A sleeve is provided at the center of the upper end of the rotating wheel. The rotating wheel is fixedly connected to the rotating shaft of the motor through the sleeve. The rotating wheel rotates under the drive of the motor. A drive column is provided on the lower end face of the rotating wheel. The drive column is located near the outer side of the rotating wheel. The central axis of the drive column is parallel to the rotating shaft of the motor. The drive column is inserted into a strip-shaped groove protruding from the side of the movable part 41 of the egg-turning tray 4. The strip-shaped groove is a through groove. When the rotating wheel rotates one revolution, the movable part 41 of the egg-turning tray 4 is completely rotated. The drive column completes a reciprocating motion with a stroke twice the eccentricity of the drive column. The drive column provides tangential force to the movable part 41 through the strip groove, converting it into linear thrust. The egg-turning tray 4 also includes a support part 42 for supporting the eggs. A limit track is provided on the surface of the support part 42 that contacts the movable part 41 to ensure that the movable part 41 moves in a straight line. After the drive column passes through the strip groove, the bolt is tightened to prevent the drive column from coming out of the strip groove. The movable part 41 has a cuboid area for accommodating the eggs. Slots are evenly arranged on the inner sides of the long sides to be used with partition plates. The two ends of the partition plates can be inserted into the slots. The partition plates can be adjusted in pairs according to the size of the eggs to accommodate the incubation of different eggs.
