Description

Technical Field

[0001] This utility model relates to a duck egg incubator. Background Technology

[0002] With the advancement of technology, egg incubation has become a crucial step in modern aquaculture. It helps farmers breed and reproduce more efficiently, improving overall farming profits. Therefore, improving egg incubation technology is of paramount importance. The principle of incubation technology is to ensure that the embryo completes development within a certain timeframe by maintaining uniform temperature, humidity, and oxygen levels. Currently, duck egg incubation typically involves placing the eggs on an incubation rack, which is then placed inside an incubation chamber. However, the eggs remain stationary after placement, leading to uneven heating and affecting the hatching success rate, a problem that urgently needs improvement. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a duck egg incubation rack that is not only reasonably structured but also has a more uniform temperature, thereby improving the hatching success rate.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a duck egg incubation rack, including a push-pull frame and an egg tray frame whose bottom is rotatably connected to the push-pull frame. The bottom of the egg tray frame is rotatably connected to the push-pull frame through a rotating shaft and through a protruding part. A swing block is fixedly connected to the rotating shaft. A C-shaped limiting plug is symmetrically arranged on both sides of the swing block and slidably connected to it. A top rod extending in the same direction as the limiting plug is fixedly connected to the lower end of the swing block. A top ring is coaxially sleeved on the outside of the top rod. The lower ends of the two limiting plugs extend horizontally and are fixedly connected to the outside of the top ring. A spring is abutted between the top ring and the swing block. The push-pull frame has two sets of limiting holes for the insertion of the two limiting plugs.

[0005] Furthermore, guide sleeves for slidable connection are symmetrically fixed on both sides of the swing block for limiting insertion.

[0006] Furthermore, top plates are symmetrically fixed on both sides of the top ring.

[0007] Furthermore, each of the limiting inserts includes a horizontal segment that is parallel to the top and bottom and a vertical segment that connects the two horizontal segments into one. The horizontal segment at the lower end is longer than the horizontal segment at the upper end. The two vertical segments of the limiting inserts are connected by a synchronous fixing plate. When the end of the horizontal segment at the upper end is inserted into the limiting hole, the synchronous fixing plate is abutted against the upper limit of the swing block.

[0008] Furthermore, the egg tray frame includes two parallel vertical frames, with a horizontal frame erected between the two vertical frames. The horizontal frame is spaced vertically and its two ends are rotatably connected to the vertical frames. The bottom horizontal frame is rotatably connected to the push-pull frame via a pivot, and the top horizontal frame is rotatably connected to the push-pull frame via a connecting pivot.

[0009] Furthermore, the bottom of each push-pull frame is equipped with omnidirectional casters.

[0010] Furthermore, a push-pull rod is fixed in the middle of the side of the push-pull frame away from the swing block to facilitate pushing and pulling.

[0011] Furthermore, the bottom of the push-pull frames on both sides of the swing block are fixedly connected with limiting strips to restrict the swing block from excessively rotating.

[0012] Compared with the prior art, the present invention has the following advantages: by swinging the swing block left and right with the top rod and the swing plate, the egg tray frame swings around the axis in a small range, so as to achieve uniform heating and incubation of duck eggs. The swing range is limited by the limiting strip to avoid excessive swinging, which is safer and more stable.

Detailed Implementation

[0019] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0020] like Figures 1-4As shown, the duck egg incubation rack includes a push-pull frame 1 and an egg tray frame 2 whose bottom is rotatably connected to the push-pull frame. The bottom of the egg tray frame is rotatably connected to the push-pull frame via a pivot 3. A swing block 4 is fixedly connected to the pivot. C-shaped limiting inserts 5 are symmetrically arranged on both sides of the swing block and slidably connected to it. A top rod 6 extending in the same direction as the limiting inserts is fixedly connected to the lower end of the swing block. A top ring 7 is coaxially sleeved on the outside of the top rod. The lower ends of the two limiting inserts extend horizontally and are fixedly connected to the outside of the top ring. A spring 8 is abutted between the top ring and the swing block. The spring is sleeved on the outside of the top rod. Two sets of limiting holes 9 are opened on the push-pull frame for the insertion of the two limiting inserts.

[0021] In this embodiment of the utility model, guide sleeves 10 for slidable connection are symmetrically fixed on both sides of the swing block for limiting insertion.

[0022] In this embodiment of the utility model, top plates 11 are symmetrically fixed on both sides of the top ring.

[0023] In this embodiment of the utility model, each limiting plug includes a horizontal segment that is parallel to the top and bottom and a vertical segment that connects the two horizontal segments into one. The horizontal segment at the lower end is longer than the horizontal segment at the upper end. The two vertical segments of the limiting plug are connected by a synchronous fixing plate 12. When the end of the horizontal segment at the upper end is inserted into the limiting hole, the synchronous fixing plate is abutted against the upper limit of the swing block.

[0024] In this embodiment of the utility model, the egg tray frame includes two parallel vertical frames 13, and a horizontal frame 14 is provided between the two vertical frames. The horizontal frame is arranged at intervals on both sides and is rotatably connected to the vertical frames at both ends. Egg trays and eggs can be placed on the horizontal frame. The bottom horizontal frame is rotatably connected to the push-pull frame through a pivot, and the top horizontal frame is rotatably connected to the push-pull frame through a connecting pivot 15.

[0025] In this embodiment of the utility model, the bottom of each push-pull frame is provided with universal casters 16.

[0026] In this embodiment of the utility model, a push-pull rod 17 is fixedly provided in the middle of the side of the push-pull frame away from the swing block to facilitate pushing and pulling.

[0027] In this embodiment of the invention, the bottom of the push-pull frames on both sides of the swing block is fixedly connected with a limiting strip 18 for limiting the excessive swing of the swing block. The limiting strip is bent downward to avoid interference with the swing of the egg tray frame.

[0028] The working principle of this utility model embodiment is as follows: After placing the eggs in the correct position, push the push-pull frame into the incubation chamber. The incubation chamber is equipped with a swing plate 19 that can swing left and right. The swing plate has a top hole 20 for the top rod to enter only. When in use, the top rod moves forward with the push-pull frame and extends into the top hole, and is pushed onto the swing plate by the top plate. Continue to push the push-pull frame, the spring is compressed and the top ring drives the limit plug to move backward. Then the limit plug disengages from the limit hole. At this time, the push-pull frame is fixed, the egg tray frame is released from the limit, and can then rotate with the swing block. The swing block swings left and right with the top rod and the swing plate, thereby driving the egg tray frame to swing around the axis of rotation in a small range. The swing range is limited by the limit strip to avoid excessive swinging, making it safer and more stable.

[0029] This utility model is not limited to the preferred embodiment described above. Anyone can derive other various forms of duck egg incubators based on the inspiration of this utility model. All equivalent variations and modifications made within the scope of the claims of this utility model shall fall within the scope of this utility model.
