Description

Technical Field

[0001] This utility model belongs to the field of silkworm rearing equipment, specifically relating to a rotating and lifting silkworm rearing device. Background Technology

[0002] To save floor space, existing silkworm rearing racks typically have multiple layers of silkworm trays placed vertically. However, the trays at higher positions are inconvenient for staff to monitor and access. To address this, patent CN202323167025.4 discloses a rotating silkworm rearing rack. By setting up a rectangular ring-shaped conveyor chain and directly connecting the silkworm trays to the conveyor chain, the conveyor chain moves the silkworm trays during operation, allowing the trays to be adjusted to a suitable height for staff to operate.

[0003] However, the above technical solutions have the following problems: When the silkworm tray moves vertically to the top or bottom of the rectangular ring-shaped conveyor chain, it will begin to move laterally. Since the silkworm tray is directly connected to the conveyor chain, it is necessary to avoid interference between the laterally moving silkworm tray and its two adjacent silkworm trays. That is, when other silkworm trays move to the top or bottom of the conveyor chain, the bottom of the laterally moving silkworm tray may collide with other silkworm trays. Therefore, in the actual design process, the spacing between adjacent silkworm trays and the width of the entire conveyor chain need to be designed, resulting in a larger overall equipment width to accommodate a certain number of silkworm trays and a larger overall equipment footprint. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a rotating and lifting silkworm rearing device to solve the problem that the existing silkworm rearing rack equipment occupies a large area.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0006] The rotating and lifting silkworm rearing equipment includes a silkworm tray mounting frame, a conveying assembly, and a connecting assembly for connecting the silkworm tray mounting frame to the conveying assembly. The conveying assembly is used to form an elliptical conveying path in a vertical plane. The connecting assembly has multiple sets along the circumference of the conveying assembly. The connecting assembly includes a connecting rod that is detachably connected to the conveying assembly. The connecting rod has two rods, and the ends of the two connecting rods facing away from the conveying assembly are connected to form a triangular structure. The ends of the connecting rods are hinged to the middle of the side of the silkworm tray mounting frame.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] In this solution, the conveying component and the silkworm tray mounting frame are connected by a connecting component. This allows the conveying component to be designed to be smaller, as long as the connecting rod extends out and connects to the silkworm tray mounting frame. Furthermore, the conveying path of the conveying component is elliptical. When the connecting rod moves to the top or bottom of the conveying component, the connecting rod extending from the conveying component will also make an arc-shaped movement. Therefore, the silkworm tray mounting frame will not actually make a purely horizontal movement, reducing the possibility of interference.

[0009] In addition, the silkworm tray mounting frame is connected by connecting rods. To reduce the possibility of deformation of the connecting rods under load or swaying of the transmission components due to the connecting rods pulling them, a triangular structure is formed by two connecting rods to improve stability.

[0010] Furthermore, the conveying assembly includes a conveying chain and a drive sprocket and a driven sprocket for chain drive connection with the conveying chain, and the connecting assembly is mounted on the conveying chain.

[0011] Furthermore, the conveying components are provided in two sets and located on both sides of the silkworm tray mounting frame. The two ends of the silkworm tray mounting frame are respectively connected to the conveying chains on both sides through connecting components.

[0012] Furthermore, a first link connects the driving sprockets of the two sets of transmission components, and a second link connects the driven sprockets of the two sets of transmission components.

[0013] Furthermore, the connecting rods of adjacent sets of connecting components are sequentially connected at one end facing the conveyor chain.

[0014] Furthermore, the conveyor chain is provided with a first connecting block, and the first connecting block has a groove. The ends of the connecting rods of adjacent connecting components are all inserted into the groove and detachably connected to the first connecting block.

[0015] Furthermore, the shortest distance from the end of the connecting rod facing away from the conveyor chain to the conveyor chain is greater than or equal to the shortest distance from the connection point between the silkworm tray mounting frame and the connecting rod to the conveyor chain.

[0016] Furthermore, the distance between the two connecting rods of the connecting assembly is less than or equal to one-third of the circumference of the drive sprocket.

[0017] Furthermore, a second connecting block is detachably connected to the side of the silkworm tray mounting frame. The end of the second connecting block protrudes from the upper surface of the silkworm tray mounting frame, and the protruding part of the second connecting block is hinged to the connecting rod.

[0018] Furthermore, the connecting rod includes a first arc segment and a second arc segment. The first arc segment is connected to the conveying assembly, and the first arc segments of the two connecting rods of the connecting assembly are bent in opposite directions. The second arc segment is connected to the silkworm tray mounting frame, and the second arc segments of the two connecting rods of the connecting assembly are bent in a direction that approaches each other.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments will be given.

[0026] like Figure 1 , Figure 2 As shown, the rotating and lifting silkworm rearing equipment includes a silkworm tray mounting frame 2, a conveying assembly, and a connecting assembly for connecting the silkworm tray mounting frame 2 to the conveying assembly. The conveying assembly forms an elliptical conveying path in a vertical plane. Specifically, in this embodiment, the conveying assembly includes a conveying chain 6 and a driving sprocket 4 and a driven sprocket 5 for chain drive connection with the conveying chain 6. The connecting assembly is mounted on the conveying chain 6. In actual design, a frame 1 is also provided, and the driving sprocket 4 and driven sprocket 5 are rotatably connected to the frame 1. Alternatively, the conveying assembly can also use existing technologies such as conveyor belts, gears, or synchronous belts, as long as the conveying function can be achieved.

[0027] Two sets of conveying components are located on both sides of the silkworm tray mounting frame 2. Both ends of the silkworm tray mounting frame 2 are connected to the conveying chains 6 on both sides via connecting components, improving the stability of conveying the silkworm tray mounting frame 2. A first connecting rod is fixedly connected between the driving sprockets 4 of the two sets of conveying components, and a second connecting rod is fixedly connected between the driven sprockets 5 of the two sets of conveying components. With this design, only one driving sprocket 4 needs to be driven to rotate. In actual design, a motor for driving the driving sprocket 4 can be installed on the frame 1, or the driving sprocket 4 can be driven to rotate in other ways, such as by installing a handle on the driving sprocket 4 for manual operation.

[0028] Multiple sets of connecting components are provided along the circumference of the conveying components, thereby allowing multiple sets of silkworm tray mounting frames 2 to be installed on the conveying components. The silkworm tray mounting frames 2 are used to place silkworm trays. In actual design, the silkworm tray mounting frames 2 can be formed by welding existing technologies such as channel steel, as long as the silkworm trays can be placed on them.

[0029] The connecting assembly includes connecting rods 3 detachably connected to the conveying assembly. Two connecting rods 3 are provided, and the ends of the two connecting rods 3 facing away from the conveying assembly are connected to form a triangular structure. The ends of the connecting rods 3 are hinged to the middle of the side of the tray mounting frame 2. To increase the number of connecting assemblies installed on the conveying chain 6, the connecting rods 3 of adjacent sets of connecting assemblies are sequentially connected to each other at the ends facing the conveying chain 6. Specifically, in conjunction with... Figure 3 As shown, the conveyor chain 6 is provided with a first connecting block 10. The first connecting block 10 can be formed by directly setting a protruding part on the conveyor chain 6, or it can be a connecting block bolted to the conveyor chain 6. The first connecting block 10 has a groove, and the ends of the connecting rods 3 of adjacent connecting components are inserted into the groove and detachably connected to the first connecting block 10. Specifically, when the ends of the two connecting rods 3 are inserted into the groove, the first connecting block 10 and the ends of the two connecting rods 3 are connected together by bolts.

[0030] To avoid interference during transmission, the shortest distance from the end of the connecting rod 3 facing away from the conveyor chain 6 to the conveyor chain 6 is greater than or equal to the shortest distance from the connection point between the silkworm tray mounting frame 2 and the connecting rod 3 to the conveyor chain 6, thus preventing interference between the silkworm tray mounting frames 2 on both sides of the conveyor chain 6. The driving sprocket 4 and the driven sprocket 5 have the same diameter, and the distance between the two connecting rods 3 of the connecting assembly is less than or equal to one-third of the circumference of the driving sprocket 4, so that the connecting assembly can smoothly pass through the top or bottom of the conveyor chain 6.

[0031] In another embodiment of this utility model, combined with Figure 2 As shown, a second connecting block 7 is detachably connected to the side of the silkworm tray mounting frame 2. Specifically, the second connecting block 7 is bolted to the silkworm tray mounting frame 2, and the end of the second connecting block 7 protrudes from the upper surface of the silkworm tray mounting frame 2. The protruding part of the second connecting block 7 is hinged to the connecting rod 3. Through the design of the second connecting block 7, the position height of the silkworm tray mounting frame 2 is slightly lower than the end of the connecting rod 3, thereby reducing the shaking of the silkworm tray mounting frame 2 during the movement with the conveyor chain 6 to a certain extent. In particular, when the connecting rod 3 moves to the top or bottom of the conveyor chain 6, the silkworm tray mounting frame 2 can maintain a certain level, and the second connecting block 7 is more likely to deflect relative to the connecting rod 3.

[0032] In another embodiment of this utility model, combined with Figure 4 , Figure 5As shown, in this embodiment, the connecting rod 3 is not designed as a straight rod. The connecting rod 3 includes a first arc segment 8 and a second arc segment 9. The first arc segment 8 is connected to the conveying component. The first arc segments 8 of the two connecting rods 3 of the connecting component are bent in opposite directions. The second arc segment 9 is connected to the silkworm tray mounting frame 2. The second arc segments 9 of the two connecting rods 3 of the connecting component are bent in a direction that approaches each other.

[0033] according to Figure 4 , Figure 5 Simulation analysis shows that when connecting rod 3 is curved, the deformation is approximately 2mm, while when it is straight, the deformation is approximately 4mm. This indicates that curved connecting rod 3 exhibits less deformation under stress and higher stiffness. Therefore, a curved design for connecting rod 3 is preferred. However, in practical applications, when the silkworm disc size is small and the weight is low, and the impact on the deformation of connecting rod 3 is minimal, a straight rod can be directly used as connecting rod 3, as straight rods are easier to manufacture.
