Description

Technical Field

[0001] The invention relates to an incubator, in particular to an incubator using a mobile egg cart. Background Art

[0002] An incubator is a device used to artificially incubate poultry eggs. According to its structure, it can be divided into tunnel incubators and box incubators. The box incubator mainly includes an incubator and an egg-turning device arranged therein. The main body of the egg-turning device is an egg rack. At present, there are two main types of egg racks: octagonal egg racks and seesaw egg racks. In comparison, the octagonal egg rack has a higher hatching rate. The octagonal egg rack is suspended between two standing feet through a rotating main shaft, and the egg-turning device is driven to rotate by a driving mechanism through a transmission mechanism. The box incubator using this egg-turning device is referred to as an octagonal incubator.

[0003] For example, the Chinese patent application number 201710291896.7 discloses a large-angle egg-turning incubator, which achieves large-angle egg turning and improves the hatching rate of poultry eggs, and is favored by enterprises. However, its egg rack is fixed in the incubator. Due to different operating procedures, some customers require an incubator with a movable egg trolley.

[0004] In order to meet the needs of the market, some incubators use mobile egg carts. The egg racks are suspended on the mobile egg carts by rotating the main shaft. In order to make the egg racks reciprocate and tilt during the incubation process, the incubator is equipped with a motor and a transmission mechanism on each mobile egg cart. The motor drives the egg racks to reciprocate and tilt through the transmission mechanism. However, the incubator brings the following problems:

[0005] 1. The weight of the mobile egg cart when it is full of poultry eggs is already very heavy, and workers need a lot of strength to move it. When a heavier motor is added, the weight of the mobile egg cart becomes even heavier, making it more difficult for workers to push the mobile egg cart;

[0006] 2. When pushing the mobile egg cart into the incubator for hatching, the power plug of the motor on each mobile egg cart needs to be inserted into the socket fixed on the incubator. When the mobile egg cart needs to be removed, the power plug of the motor on the mobile egg cart needs to be unplugged from the socket. This undoubtedly increases the workload of the workers and makes the operation of the incubator more complicated.

[0007] 3. The installation of a motor on each mobile egg trolley undoubtedly increases the cost of the incubator and also increases the power of the incubator;

[0008] 4. When moving the mobile egg cart out of the incubator, if you want to rotate the egg rack to a certain angle, you need to find another socket to provide power to the motor. Summary of the invention

[0009] The technical problem to be solved by the present invention is to provide a mobile egg trolley type incubator with reasonable structure and simple operation.

[0010] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0011] A mobile egg trolley incubator comprises an incubator, an incubation adjustment system, at least one egg rack and at least one mobile egg trolley, wherein the egg rack is suspended on the mobile egg trolley through a rotating main shaft, a transmission mechanism is provided on the mobile egg trolley, and a parking space is provided in the incubator corresponding to each mobile egg trolley. The invention is characterized in that: the incubator further comprises a power source and a transmission shaft assembly, wherein the transmission shaft assembly and the power source are both fixedly mounted on the incubator, the power source is connected to the input shaft of the transmission shaft assembly, an output shaft is provided in the transmission shaft assembly corresponding to each parking space, a fixed docking piece is provided at the end of each output shaft, a docking shaft connected to its transmission mechanism is provided on each mobile egg trolley, and a mobile docking piece is provided at the end of each docking shaft; when the mobile egg trolley moves into the parking space, the mobile docking piece automatically docks with the corresponding fixed docking piece to transmit the power of the power source to the transmission mechanism, and the egg rack is driven to rotate through the transmission mechanism.

[0012] As a further refined structure of the present invention: the fixed docking piece includes a clamping column, which is fixedly inserted at the end of the output shaft and extends radially along the output shaft. The movable docking piece includes a docking column and a spring. A middle hole is provided in the middle of the docking column. One end of the docking column can be slidably mounted on the end of the docking shaft through the middle hole, and the docking column can drive the docking shaft to rotate together. A cross groove is provided at the other end of the docking column, and a step is provided on the docking shaft. The spring is movably sleeved on the docking shaft and compressed between the step and the docking column. When in use, the end of the output shaft is correspondingly inserted into the middle hole of the end of the docking column with the cross groove, and the clamping column is clamped in the cross groove to achieve docking.

[0013] Furthermore, the cross-section of the end of the docking shaft connected to the docking column is a polygon, the cross-section of the middle hole is a corresponding polygon, and a slide groove extending along its axial direction is provided at the end of the docking shaft connected to the docking column, and a pin is inserted on the side wall of the docking column, and the end of the pin extending into the middle hole is located in the slide groove.

[0014] Furthermore, a sleeve is sleeved on the butt joint shaft, and the end surface of the sleeve serves as a step.

[0015] Furthermore, the drive shaft assembly includes multiple drive shafts and multiple steering gears. A steering gear is fixedly arranged corresponding to each parking space. The output shaft is connected to the corresponding steering gear. Adjacent steering gears are connected through the drive shaft. The input shaft is connected to one of the steering gears, thereby transmitting power from the power source to each output shaft.

[0016] Furthermore, the power source is a reduction motor, and the rotating shaft of the reduction motor is connected to the input shaft.

[0017] Furthermore, the transmission mechanism includes a screw rod, a nut and a guide rod. The screw rod is vertically rotatably supported on the mobile egg cart, the guide rod is fixed on the egg rack, and the guide rod is arranged radially along the rotating main shaft. The nut is threadedly connected to the screw rod, and a horizontal guide tube is fixed on the nut. The guide tube is movably sleeved on the guide rod, and one end of the screw rod is connected to the docking shaft through a coupling.

[0018] Furthermore, each parking space is provided with a guide groove, and in the process of moving the mobile egg trolley into or out of the parking space, the wheels of the mobile egg trolley move along the guide groove.

[0019] Furthermore, the mobile egg trolley-type incubator is provided with an electromagnet corresponding to each parking space, the electromagnet is fixed on the incubator box and located at the inner end of the parking space, and a metal piece is fixed on the mobile egg trolley at the position corresponding to the electromagnet.

[0020] Furthermore, the hatching regulation system includes a humidity regulation system, a temperature regulation system, a water spray system, an air circulation system and a controller.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention only needs to set up one power source, which is distributed to each mobile egg trolley through the transmission shaft assembly. The structure is reasonable, the weight of the mobile egg trolley will not be increased, the power of the incubator will not be increased, and the cost is low. The mobile egg trolley and the transmission shaft assembly are automatically connected by the mobile docking piece and the fixed docking piece, which is simple to operate and does not increase the workload of workers.

[0023] 2. When the mobile egg cart of the present invention is moved out of the incubator to load eggs, in order to conveniently place the egg tray and poultry eggs on the egg rack, the egg rack needs to be rotated to a certain angle. At this time, it is only necessary to dock the mobile docking piece of the docking shaft with the handle with the fixed docking piece, and then manually rotate the handle to rotate the egg rack to a certain angle, which is convenient and simple to operate.

[0024] 3. The fixed docking part of the present invention is fastened into the cross groove of the docking column of the movable docking part through its clamping column, so as to achieve quick docking. Even if the clamping column fails to align with the cross groove during docking, the docking column is always pressed on the clamping column under the elastic force of the spring. When the power source is started to drive the output shaft to rotate, the clamping column will slide along the end surface of the docking column and then be clamped into the cross groove.

[0034] The present invention is further described below in conjunction with embodiments.

[0035] like Figures 1 to 5 The mobile egg trolley incubator shown comprises an incubator box 41, an incubation adjustment system, at least one egg rack 32, at least one mobile egg trolley 31, a power source 24 and a transmission shaft assembly.

[0036] The egg rack 32 is suspended on the mobile egg cart 31 by rotating the main shaft 33. The mobile egg cart 31 is provided with a transmission mechanism, and a parking space 43 is provided in the incubator corresponding to each mobile egg cart 31. In this embodiment, four mobile egg carts 31 and four egg racks 32 are provided, and one egg rack 32 is provided on each mobile egg cart 31. Of course, two or more egg racks 32 can also be provided on one mobile egg cart 31, and four parking spaces 43 are provided in the incubator 41, and the four parking spaces 43 are arranged side by side horizontally.

[0037] There is one power source 24, which is fixedly mounted on the incubator 41. The power source 24 of this embodiment is a reduction motor, which is fixed on the middle of the incubator 41. Of course, the power source 24 can also be other power equipment, and the power source 24 can also be installed at other positions of the incubator 41, both outside and inside. The transmission shaft assembly is fixedly mounted on the incubator 41, and the power source 24 is connected to the input shaft 23 of the transmission shaft assembly. The transmission shaft assembly is respectively provided with an output shaft 15 corresponding to each parking space 43, so that the power of the power source 24 is distributed to each parking space 43 through the transmission shaft assembly.

[0038] In order to transmit the power transmitted to the output shaft 15 to the mobile egg cart 31, the mobile egg cart type incubator is provided with a fixed docking piece at the end of each output shaft 15, a docking shaft 11 connected to its transmission mechanism is provided on each mobile egg cart 31, and a mobile docking piece is provided at the end of each docking shaft 11. When the mobile egg cart 31 moves into the parking space 43, the mobile docking piece automatically docks with the corresponding fixed docking piece to transmit the power of the power source 24 to the transmission mechanism, and drives the egg rack 32 to rotate through the transmission mechanism.

[0039] like Figures 5 to 8 As shown, the structure of the fixed docking member of this embodiment is: the fixed docking member includes a clamping column 14, the clamping column 14 is fixedly inserted at the end of the output shaft 15, and the clamping column 14 extends radially along the output shaft 15, and the specific installation structure of the clamping column 14 is: the clamping column 14 passes through the radial through hole at the end of the output shaft 15, and the clamping column 14 is fixedly connected to the output shaft 15, such as welding, and both ends of the clamping column 14 are exposed and symmetrical with the axis of the output shaft 15. The structure of the mobile docking member of this embodiment is as follows: the mobile docking member includes a docking column 13 and a spring 12, a middle hole 131 is provided in the middle of the docking column 13, one end of the docking column 13 can be slidably mounted on the end of the docking shaft 11 through the middle hole 131, and the docking column 13 can drive the docking shaft 11 to rotate together, the other end of the docking column 13 is provided with a cross groove 132, the groove width of the cross groove 132 corresponds to the diameter of the clamping column 14, the diameter of the middle hole 131 at the end of the docking column 13 with the cross groove 132 is larger than the diameter of the output shaft 15, a step 112 is provided on the docking shaft 11, the spring 12 is movably mounted on the docking shaft 11, and is compressed between the step 112 and the docking column 13.

[0040] When the mobile egg cart 31 is pushed into the parking space 43 in the incubator 41, two situations may occur: the first situation is as follows: Figure 7 As shown, the clamping column 14 is just inserted into the cross groove 132, and the end of the output shaft 15 is inserted into the middle hole 131. At this time, the power source 24 is started to transmit power to the transmission mechanism, and the egg rack 32 is driven to rotate through the transmission mechanism; the second case, as Figure 8 As shown, the clamping column 14 is not aligned with the cross groove 132. Under the elastic force of the spring 12, the end face of the docking column 13 of the mobile docking piece will always be pressed on the corresponding clamping column 14. At this time, the power source 24 is started, and the output shaft 15 rotates under the drive of the power source 24, which will drive the clamping column 14 to slide along the end face of the docking column 13. When sliding until the clamping column 14 is aligned with the cross groove 132, the clamping column 14 can still automatically snap into the cross groove 132, and the end of the output shaft 15 is inserted into the middle hole 131 to achieve a stable connection.

[0041] The installation structure of the docking column 13 of this embodiment is as follows: the cross section of the end of the docking shaft 11 connected to the docking column 13 is hexagonal, and the cross section of the middle hole 131 is also a corresponding hexagon. The hexagonal middle hole cooperates with the hexagonal end of the docking shaft to achieve the slidable assembly of the docking column 13, and the docking column 13 can drive the docking shaft 11 to rotate together. In order to prevent the docking column 13 from being pushed out under the elastic force of the spring 12, a slide groove 111 extending along the axial direction of the docking shaft 11 is also provided at the end of the docking shaft 11 connected to the docking column 13. A pin 17 is inserted on the side wall of the docking column 13. The end of the pin 17 extending into the middle hole 131 is located in the slide groove 111. The end of the pin 17 extending into the middle hole can slide along the slide groove 111, and the two ends of the slide groove 111 do not pass through the end surface of the docking shaft 11. The connection structure using the pin 17 also makes the installation and disassembly of the docking column 13 simpler.

[0042] The step structure is as follows: a sleeve 16 is sleeved on the docking shaft, and the end face of the sleeve 16 serves as a step 112. One end face of the sleeve 16 in this embodiment abuts against the spring 12 as the step 112, and the other end face abuts against the coupling 18 used to connect the docking shaft 11 with the transmission mechanism. Figure 3 As shown, a vertical support column 37 is also fixed on the mobile egg cart, a support tube 38 is fixed on the support column 37, and the sleeve 16 is movably inserted into the support tube 38, so as to limit the position of the sleeve 16 and the docking shaft 11.

[0043] The structure of the transmission shaft assembly is as follows: the transmission shaft assembly includes a plurality of transmission shafts 22 and a plurality of steering gears 21, a steering gear 21 is fixedly arranged corresponding to each parking space 43, the output shaft 15 is connected to the corresponding steering gear 21, adjacent steering gears 21 are connected through the transmission shaft 22, and the input shaft 23 is connected to one of the steering gears 21, so as to transmit the power of the power source 24 to each output shaft 15. Figure 2 and Figure 4 As shown, this embodiment is provided with five steering gears 21 and four transmission shafts 22. The five steering gears 21 are arranged horizontally and fixed on the back plate of the incubator 41 respectively. The two steering gears on the left and the two steering gears on the right correspond to the parking spaces 43 respectively and are connected with output shafts 15 respectively. The middle steering gear corresponds to the reduction motor. The lower end of the input shaft 23 is connected to the middle steering gear, and the upper end is connected to the rotating shaft of the reduction motor. The specific number and specific installation structure of the steering gears 21 and the transmission shaft 22 will be adjusted accordingly according to the different installation positions of the reduction motor.

[0044] The steering gear 21 is a conventional device, and its structure may be: meshing bevel gears are provided inside, and steering is achieved through the cooperation between the bevel gears.

[0045] like Figure 3As shown, the transmission mechanism of this embodiment includes a screw rod 36, a nut 35 and a guide rod 71. The screw rod 36 is vertically rotatably supported on the mobile egg cart 31, and the rotation support can be realized by a bearing. The guide rod is fixed on the egg rack 32, and the guide rod is arranged along the radial direction of the rotating main shaft 33. The nut 35 is threadedly connected to the screw rod 36. A guide tube 72 is rotatably arranged on the nut 35. The guide tube 72 is rotatably arranged through a connecting shaft thereon. The guide tube 72 is movably sleeved on the guide rod 71. One end of the screw rod 36 is connected to the docking shaft 11 through a coupling 18, so that the screw rod 36 can be driven to rotate through the docking shaft 11, thereby driving the egg rack 32 to rotate. When the screw rod 36 rotates to drive the nut 35 to move upward or downward, it will drive the egg rack 32 to rotate, and the guide tube 72 will slide on the guide rod 71.

[0046] In order to enable the mobile egg cart 31 to move into the parking space 43 more smoothly and accurately, in this embodiment, two guide grooves 42 are respectively provided on each parking space 43. When the mobile egg cart 31 is moved into or out of the parking space 43, the two rows of wheels 34 of the mobile egg cart 31 move along the two guide grooves 42 respectively.

[0047] The mobile egg cart type incubator of this embodiment is provided with an electromagnet (not shown in the figure) corresponding to each parking space 43, the electromagnet is fixed on the incubator box 41 and is located at the inner end of the parking space 43, and a metal piece is fixed on the mobile egg cart 31 at the position corresponding to the electromagnet, and the metal piece of this embodiment is the cross bar 39 inside the mobile egg cart 31. When in use, before pushing the mobile egg cart 31, the electromagnet is turned on first, and when the mobile egg cart is moved into the parking space 43, the electromagnet automatically absorbs the metal piece, thereby pulling the mobile egg cart 31 inward and fixing the mobile egg cart 31. At this time, the spring 12 of the mobile docking member is in a compressed state, and the elastic force of the spring 12 will not push the mobile egg cart 31 outward.

[0048] If the mobile egg trolley incubator is not equipped with an electromagnet, the mobile egg trolley needs to use wheels with foot brakes, or use wedge-shaped wooden blocks to support the wheels, or other fixed structures to fix the mobile egg trolley in the parking space.

[0049] The hatching adjustment system comprises a humidity adjustment system, a temperature adjustment system, a water spray system, an air circulation system and a controller. The air circulation system of the present embodiment adopts a fan 51, the humidity adjustment system adopts a hygrometer and an automatic humidifying device 61 in Chinese Patent 2011200781864, the water spray system adopts an automatic water spray cooling egg device in Chinese Patent 2013202048595, and the temperature adjustment system mainly adopts a heating strip and a thermometer. The controller is installed on the incubator 41, adopts a control box, and is electrically connected to each functional module of the incubator.

[0050] The above embodiments of the present invention are not intended to limit the protection scope of the present invention, and the implementation modes of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structures of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in the art, without departing from the above basic technical ideas of the present invention, should fall within the protection scope of the present invention.
