[0030] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0031] Current waterfowl hatching equipment generally adopts an internal fixed frame structure, which has advantages such as a large egg-turning angle and strong wind penetration, and can effectively meet the basic needs of duck and goose egg hatching.

[0032] However, this type of equipment has significant drawbacks in practical applications: because the eggs are fixed inside the frame, the water cooling process during egg drying is extremely inconvenient. Specifically, the operating space is limited, and the water flow is uneven, which affects the heat dissipation efficiency of the eggs, easily causing an unstable embryonic development environment, and ultimately making it difficult to achieve ideal hatching and chick survival rates.

[0033] like Figures 1 to 4 As shown, the present invention provides a wheeled octagonal egg cart without power supply. The wheeled octagonal egg cart is installed inside the incubator box 100. Specifically, the wheeled octagonal egg cart includes a support frame 2, an octagonal egg rack 1 and a transmission mechanism 10 disposed above the support frame 2.

[0034] The octagonal egg rack 1 includes two support frames 5 arranged opposite to each other and an octagonal frame 6 located between the two support frames 5. A rotating shaft 7 is transversely provided in the middle of the octagonal frame 6, and the two ends of the rotating shaft 7 are respectively passed through the two support frames 5.

[0035] The rear end of the octagonal frame 6 is provided with a driven non-full gear 8, which is located outside the rotating shaft 7;

[0036] The support frame 5 is provided with a drive gear 9. Specifically, the drive gear 9 is rotatably mounted on the support frame 5.

[0037] The driven non-full gear 8 is engaged with the driving gear 9, and the transmission mechanism 10 is used to drive the driving gear 9 to rotate;

[0038] The octagonal egg rack 1 includes two support frames 5 and an octagonal frame 6 located between the two support frames 5. A rotating shaft 7 is horizontally inserted through the middle of the octagonal frame 6, and the two ends of the rotating shaft 7 are respectively inserted through the two support frames 5. That is, the octagonal frame 6 is rotatably positioned between the two support frames 5 through the rotating shaft 7 in the middle. The bottom of the support frame 5 is fixed to the top surface of the support frame 2. The octagonal frame 6 has multiple layers of mounting partitions inside. The mounting partitions are used to place the egg rack, and the egg rack is used to place hatching eggs. The number of mounting partitions in the octagonal frame 6 is not less than 14 layers. The number of mounting partitions in the octagonal frame 6 is preferably 14 layers.

[0039] The octagonal egg rack 1 employs a symmetrically arranged support structure with two support frames 5, and a rotatable octagonal frame 6 is positioned between the two support frames 5. This octagonal frame 6 innovatively adopts a centrally located rotating shaft design, with its rotating shaft 7 passing laterally through the geometric center of the octagonal frame 6. Both ends of the rotating shaft 7 can be mounted in corresponding shaft holes of the two support frames 5 via precision bearings. This structural layout allows the octagonal frame 6 to rotate smoothly between the two support frames 5 with the rotating shaft 7 as its center of rotation.

[0040] The structural design of the octagonal egg rack 1 has the following advantages: First, it has strong structural stability: the double load-bearing frame design effectively distributes the load and improves the overall mechanical strength; second, it has a reasonable rotating mechanism: the centrally located rotating shaft realizes the balanced movement of the rotating frame and reduces the risk of off-center loading; third, it has high assembly precision: the positioning structure at both ends of the rotating shaft 7 ensures the coaxiality of the rotating parts; fourth, it has strong maintenance convenience: the modular design makes it easy to replace the load-bearing frame 5 or the octagonal frame 6 components separately.

[0041] The octagonal frame 6 has a driven incomplete gear 8 at its rear end. This driven incomplete gear 8 can be fixedly mounted at the rear end of the octagonal frame 6. The rotation of the driven incomplete gear 8 can drive the octagonal egg rack 1 to rotate. The driven incomplete gear 8 is located outside the rotating shaft 7. A driving gear 9 meshes with the driven incomplete gear 8. The driving gear 9 is rotatably mounted on the support frame 5. The transmission mechanism 10 is used to drive the driving gear 9 to rotate forward or backward. That is, the driving gear 9 is connected to the driven incomplete gear 8 through meshing. The driving gear 9 is rotatably mounted on the support frame 5 and is driven to rotate forward or backward by the transmission mechanism 10. By driving the driving gear 9 to rotate forward or backward through the transmission mechanism 10, the driven incomplete gear 8 can be driven to rotate forward or backward, thereby driving the octagonal frame 6 to swing, achieving precise rotation control. This allows for automatic egg turning while facilitating water flushing and heat dissipation, thus achieving uniform water flushing, improving heat dissipation rate, and being more conducive to hatching and hatching results, increasing the hatching rate and the survival rate of chicks.

[0042] In addition, the driven non-full gear 8 is fan-shaped or semi-circular, and the teeth of the gear are located on the arc-shaped edge;

[0043] The transmission mechanism 10 can be a chain drive or a belt drive;

[0044] The structural design of the support frame 5, the octagonal frame 6, and the transmission mechanism 10 has the following advantages:

[0045] First, the structure is compact. The design of the support frame 5 and the octagonal frame 6 in the middle are arranged opposite each other to form a stable support system, which effectively reduces the space occupied by the overall equipment. Combined with the design of the rotating shaft 7 running horizontally through the middle of the octagonal frame 6, it can not only ensure the structural strength but also improve the space utilization. Second, the transmission is precise. Through the special meshing design of non-full gears (that is, the cooperation between the driving gear 9 and the driven non-full gear 8), the meshing connection is highly reliable, the egg turning is smooth, and the precise angle control of the octagonal frame 6 can also be achieved. When the driving gear 9 drives the driven non-full gear 8 to rotate, a preset stop position can be achieved for precise positioning, which is particularly suitable for industrial scenarios that require intermittent rotation; thirdly, the power transmission stability is achieved by the through-type fit design of the rotating shaft 7 and the octagonal frame 6, which, together with the precision meshing transmission of the gear set, forms a stable power transmission path. Moreover, this connection structure can effectively eliminate vibration deviation during the transmission process, ensuring the smooth operation of the octagonal frame 6; fourthly, the modular maintenance advantage is achieved by adopting a separate component design (the load-bearing frame 5, the octagonal frame 6, and the transmission mechanism 10 are set independently). Each functional module can work together and can also be disassembled and maintained individually. In particular, the separate structure of the driving gear 9 and the transmission mechanism 10 greatly simplifies the daily maintenance and component replacement process.

[0046] like Figures 1 to 4 As shown, in some embodiments of this utility model, the driven non-full gear 8 is fan-shaped or semi-circular, and the teeth of the gear are located on the arc-shaped edge. The driven non-full gear 8 is preferably semi-circular. Both ends of the driven non-full gear 8 are provided with stop portions 81 in an integral molding manner. By setting the stop portions 81, the rotation angle of the driven non-full gear 8 is ensured to be appropriate.

[0047] like Figures 1 to 4 As shown, in some embodiments of this utility model, the support frame 2 includes a supporting base plate 3 and movable wheels 4 located at the four corners of the bottom surface of the supporting base plate 3. Specifically, the four movable wheels 4 are symmetrically arranged at the four corners of the bottom surface of the supporting base plate 3. Each movable wheel 4 includes a movable mounting seat and a wheel body. The movable mounting seat can be fixed to the bottom of the supporting base plate 3 by welding and / or bolting. The wheel body is rotatably disposed below the movable mounting seat.

[0048] The symmetrically distributed four-corner casters 4 form a rectangular support structure, which, together with the rigid load-bearing base plate 3, effectively improves the overall stability of the equipment and prevents tilting. The evenly distributed design of the four support points can evenly distribute the load-bearing pressure to each caster 4, avoiding single-point overload and extending the service life of the wheel set. The four-wheel configuration takes into account both load-bearing and movement performance, and has better ground adaptability than the traditional three-point support, enabling multi-directional smooth movement. The design of integrating the casters 4 into the bottom of the load-bearing base plate 3 maximizes the preservation of the flat working surface in the central area of ​​the base plate, facilitating the expansion of equipment functions.

[0049] like Figures 1 to 4 As shown, in some embodiments of this utility model, the tooth surfaces of both the driven non-full gear 8 and the driving gear 9 are provided with a wear-resistant coating.

[0050] By applying a wear-resistant coating to the tooth surfaces of both the driven non-full gear 8 and the driving gear 9, the tooth surface wear rate can be effectively reduced, the frequency of subsequent maintenance can be reduced, and the service life of the gear pair can be extended. In addition, the wear-resistant coating can reduce meshing power loss, buffer meshing impact, and reduce gear transmission noise.

[0051] like Figures 1 to 4 As shown, in some embodiments of this utility model, the transmission mechanism 10 includes an egg cart turning speed reducer 103, a drive sprocket, a driven sprocket, and a chain. The chain is wrapped around the outside of the drive sprocket and the driven sprocket. In addition, the transmission mechanism 10 also includes a connecting shaft 102, which is used to connect an egg turning speed reducer motor 101 externally. One end of the connecting shaft 102 away from the egg turning speed reducer motor 101 is connected to the egg cart turning speed reducer 103.

[0052] The drive sprocket is located at the output end of the egg-turning reducer 103 of the egg cart.

[0053] The driven sprocket and the driving gear 9 are coaxially arranged;

[0054] The mounting base of the egg-turning gear motor 101 is located outside the incubator box 100. Specifically, the mounting base of the egg-turning gear motor 101 is fixed to the outside of the incubator box 100 by bolt connection, which facilitates subsequent disassembly, inspection, maintenance and other operations.

[0055] The mounting base for the egg-turning reducer 103 is located on the top of the support frame 2;

[0056] The system composition of the transmission mechanism 10 and the power transmission path of the egg-turning geared motor 101 can be implemented as follows: the egg-turning geared motor 101 is electrically driven, integrating a motor and a first-stage reduction mechanism, outputting low-speed, high-torque power; a mounting shaft 105 is provided at the output end of the egg-turning geared motor 101, and the connecting shaft 102 can connect the mounting shaft 105 at the output end of the egg-turning geared motor 101 to the input shaft of the egg cart egg-turning reducer 103 through a coupling to transmit power; since the egg cart egg-turning reducer 103 is not electrically driven, it is a passive transmission component. It receives the power input from the egg-turning geared motor 101 and can perform secondary reduction (or speed change) through an internal gear set or worm gear mechanism to further increase the output torque; the driving sprocket is installed on the output shaft of the egg-turning reducer 103 as the final output. This driving sprocket drives the driven sprocket through a chain to complete the power transmission;

[0057] The driven sprocket and the driving gear 9 are coaxially arranged. Therefore, the rotation of the driven sprocket will drive the operation of the driving gear 9, thereby realizing the rotational motion of the driving gear 9.

[0058] like Figures 1 to 4 As shown, in some embodiments of this utility model, a shaft hole is provided at the end of the connecting shaft 102 that is away from the egg cart egg-turning reducer 103, and a pin 104 is provided in the shaft hole, which is perpendicular to the connecting shaft 102.

[0059] Specifically, an installation shaft 105 can be provided at the output end of the egg-turning gear motor 101. An installation groove adapted to the connecting shaft 102 is provided at one end of the installation shaft 105 away from the output end of the egg-turning gear motor 101. A limit groove is also provided at the outer end of the installation shaft 105 away from the output end of the egg-turning gear motor 101. The limit groove is connected to the installation groove and is adapted to the pin shaft 104.

[0060] In actual use, by pushing the egg cart into the incubator box 100, inserting the connecting shaft 102 into the mounting groove of the mounting shaft 105, and fitting the pin 104 into the limiting groove, the connection between the connecting shaft 102 and the mounting shaft 105 at the output end of the egg-turning reduction motor 101 can be completed. Then, through the operation of the egg-turning reduction motor 101, power is transmitted to the egg cart egg-turning reducer 103. The drive sprocket is installed on the output shaft of the egg-turning reducer 103 as the final output. The drive sprocket drives the driven sprocket through the chain to complete the power transmission.

[0061] Since the transmission mechanism 10 drives the drive gear 9 to achieve rotational motion through the egg cart egg-turning reducer 103, its structure includes the following core components: 1. A transmission assembly consisting of a drive sprocket and a driven sprocket; 2. A chain transmission system wrapped around the outer circumference of the two sprockets.

[0062] In addition, the egg-turning geared motor 101 serves as an external power source, and its mounting base can be fixed to the outside of the incubator box 100. Specifically, the mounting base of the egg-turning geared motor 101 can be fixed to the outside of the incubator box 100 by bolt connection, thereby ensuring that the wheeled octagonal egg cart without power supply achieves the purpose of wireless power supply. Among them, the mounting shaft 105 of the output end of the egg-turning geared motor 101 is connected to the connecting shaft 102, and the connecting shaft 102 is then connected to the egg cart egg-turning reducer 103. The output end of the egg cart egg-turning reducer 103 is connected to the drive sprocket, which drives the driven sprocket to rotate through chain drive. The driven sprocket adopts a coaxial design and is rigidly connected to the drive gear 9, forming an efficient power transmission path, thereby realizing the rotation of the drive gear 9.

[0063] The advantages of this transmission scheme are that it adopts a sprocket and chain drive structure, which has the characteristics of high transmission efficiency and strong load capacity; the design of the egg-turning geared motor 101 being independently installed outside the incubator box 100 ensures the stability of power transmission and facilitates equipment maintenance; at the same time, the coaxial setting of the driven sprocket and the driving gear 9 can effectively reduce the number of transmission stages, reduce energy loss, and improve transmission accuracy.

[0064] In addition, the octagonal egg rack 1 and the egg-turning reduction motor 101 are connected by an independent external connection, without plugs or wiring. There are no electrical appliances on the egg cart, and it is waterproof, moisture-proof, and corrosion-proof, avoiding the malfunctions caused by poor contact and aging and carbonization of the push rod type egg cart due to frequent plugging and unplugging of the plug.

[0065] like Figures 1 to 4 As shown, in some embodiments of this utility model, the mounting base of the egg cart egg-turning reducer 103 is fixed to the top of the support frame 2 by bolt connection; this structural design not only ensures the installation positioning accuracy, but also provides convenient disassembly and assembly conditions for subsequent equipment maintenance.

[0066] like Figures 1 to 4 As shown, in some embodiments of this utility model, the chain surface is provided with an anti-rust coating; the anti-rust coating can be formed by electroplating a metal layer on the chain surface using an electroplating process. The material of the anti-rust coating can be a zinc-nickel alloy. The anti-rust coating can not only effectively isolate oxygen and moisture corrosion, but also withstand chemical corrosion.

[0067] like Figures 1 to 4 As shown, in some embodiments of this utility model, the rotating shaft 7 and the support frame 5 are both made of stainless steel.

[0068] Both the rotating shaft 7 and the support frame 5 are made of stainless steel, which has excellent corrosion resistance and can effectively resist the erosion of harsh environments such as humidity, acids and alkalis, thereby significantly extending the service life of the equipment and reducing maintenance costs. Stainless steel has high strength and can withstand large loads and impacts, ensuring that the rotating shaft 7 and the support frame 5 remain stable during operation and improving the overall reliability of the equipment. In addition, the surface of stainless steel is smooth and not easy to get dirty, which facilitates daily cleaning and maintenance, helps to keep the equipment in good condition and reduce the failure rate.

[0069] like Figures 1 to 4 As shown, in some embodiments of this utility model, the driven non-full gear 8 is fixed to the outside of the octagonal egg rack 1 by bolt connection; that is, the driven non-full gear 8 is fixedly installed to the rear side of the octagonal egg rack 1 by standard bolt connection.

[0070] The bolted connection method can achieve rigid fixation between the driven non-full gear 8 and the octagonal machine egg frame 1, ensuring stable operation of the transmission system; the modular design of the bolted connection facilitates subsequent disassembly and maintenance, reducing equipment maintenance costs; the design of placing the driven non-full gear 8 externally on the octagonal machine egg frame 1 can effectively utilize the external space of the equipment and avoid interference with the internal structure.

[0071] like Figures 1 to 4 As shown, in some embodiments of this utility model, the support frame 5 is fixed to the top of the support frame 2 by welding and / or bolting, and a single connection method or a combination of methods can be selected according to actual working conditions.

[0072] like Figures 1 to 4 As shown, in some embodiments of this utility model, the distance between the two support frames 5 is d1, and the length of the rotating shaft 7 is d2.

[0073] The ratio of d1 to d2 is 1-1.2, and the preferred ratio of d1 to d2 is 1.1-1.2;

[0074] Since the two ends of the rotating shaft 7 need to be respectively mounted on two support frames 5, specifically, mounting holes can be provided on the support frames 5, and the two ends of the rotating shaft 7 are respectively mounted in the mounting holes on the two support frames 5. To ensure assembly feasibility and operational stability, the length of the rotating shaft 7 must meet the basic requirement of not being less than the distance between the two support frames 5. Based on this structural constraint, the ratio of d1 to d2 should be controlled within the range of 1-1.2.

[0075] This structural design can effectively improve structural stability and load distribution uniformity. The ratio of the length of the shaft 7 to the distance between the two support frames 5 (i.e., the ratio of d1 to d2 is 1-1.2) can ensure the rigidity of the shaft 7 and reserve reasonable assembly tolerance space for the mechanical system, ensuring that no jamming occurs during operation.

[0076] This utility model provides a wheeled octagonal egg-turning machine cart without a power supply. The meshing connection between the driven non-full gear and the driving gear is highly reliable and the egg-turning is smooth. The egg rack of the octagonal machine adopts an independent external connection with the external motor, without plugs, wires, or electrical appliances on the egg cart. It is waterproof, moisture-proof, and corrosion-proof, avoiding the failures caused by poor contact and aging and carbonization of the push rod caused by frequent plugging and unplugging of the push rod type egg cart. The wheeled octagonal egg-turning machine cart is easy to transport and can effectively improve work efficiency.

[0077] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
