Description

Technical Field

[0001] This application relates to the field of silkworm rearing technology, specifically to a silkworm rearing frame. Background Technology

[0002] The silkworm is an important economic insect and a major source of raw materials for silk production. Silkworm rearing requires the use of silkworm racks. These racks typically have a multi-tiered structure, allowing multiple trays or platforms to be placed within a limited indoor space. Different tiers of the rack enable separate rearing of silkworms, facilitating classification and observation based on their growth stage and health condition. For example, small, large, and mature silkworms can be placed on different tiers and reared with different methods. This significantly increases the number of silkworms raised per unit area, effectively utilizes space resources, and meets the needs of large-scale silkworm rearing.

[0003] For example, the automated silkworm rearing rack device authorized by China with the publication number CN 219894324 U discloses that the present invention uses a power component to drive the rack to move, so as to realize the pop-out and retraction of the silkworm tray, increase the convenience of picking up and putting down the silkworm tray, and at the same time save labor costs and reduce breeding costs.

[0004] However, most silkworm rearing frames currently have a fixed spacing between layers, which requires frequent bending and movement when feeding mulberry leaves and removing sand from the bottom layer, increasing labor intensity and reducing work efficiency. At the same time, it is not easy to adjust the spacing between layers. Utility Model Content

[0005] Therefore, this application provides a silkworm rearing frame to solve the problem that the fixed spacing between the layers of the existing silkworm rearing frame leads to frequent bending and movement when feeding mulberry leaves and removing sand from the bottom layer, and at the same time, it is not convenient to adjust the spacing between the layers.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A silkworm rearing frame includes: an installation frame, a fixing plate, and a fixing rod. A winding assembly is provided at the upper middle part of the installation frame, and multiple sets of placement racks are provided on the inner side of the installation frame. A bottom plate is installed on the inner bottom of the placement rack.

[0008] Each of the multiple sets of placement racks has a fixed plate fixedly installed on both the left and right sides. A guide wheel is fixedly installed on the upper outer side of one set of fixed plates, and a steel rope is provided on the outer side of the guide wheel.

[0009] A fixing rod is fixedly installed on the lower outer side of the fixing plate, and a steel chain is sleeved on the outer side of the fixing rod. A fixing nut located outside the steel chain is installed on the outer side of the fixing rod to prevent the steel chain from falling off.

[0010] Furthermore, the winding assembly includes a geared motor, a drive shaft, and a winding reel. The geared motor is installed at the top center of the mounting frame, and the output end of the geared motor is connected to the drive shaft. Multiple winding reels are fixedly installed in the middle of the drive shaft.

[0011] Furthermore, the winding reel and the steel rope are arranged in a one-to-one correspondence, and the steel rope is wound around the outer side of the middle part of the winding reel.

[0012] Furthermore, the upper end of the fixing plate is lower than the top height of the placement frame, and the longitudinal section of the fixing plate is "L" shaped.

[0013] Furthermore, each of the upper outer sides of the multiple sets of fixing plates is fixedly installed with a mounting ring, and the mounting ring is connected to the lower end of the steel chain.

[0014] Furthermore, a limiting block is fixedly installed on the side wall of the placement rack, and the limiting block is slidably connected to the mounting frame to limit the movement of the placement rack.

[0015] Furthermore, the fixing rod is located directly above the mounting ring, and the top of the steel chain can slide on the outside of the fixing rod, so that multiple sets of placement racks can be stably stacked in sequence.

[0016] Compared with the prior art, this application has at least the following beneficial effects:

[0017] 1. By starting the geared motor, the drive shaft and winding reel rotate, facilitating the winding of the steel rope. This, in turn, moves the first-layer placement frame upwards to a comfortable operating height for workers, allowing them to perform sludge removal and sanding operations on the first layer. As the first-layer placement frame moves upwards, the steel chain between it and the second-layer placement frame is pulled vertically, thus moving the second-layer placement frame upwards to a comfortable operating height for workers. Similarly, multiple placement frames are sequentially moved upwards, reaching comfortable operating heights for workers in succession. This effectively reduces frequent bending and movement by workers, lowers labor intensity, and improves work efficiency.

[0018] 2. By rotating the fixing nut, the fixing nut is separated from the fixing rod. Then, the ring connecting the steel chain to the fixing rod is removed. The ring at a suitable length on the steel chain is then fitted onto the outside of the fixing rod. Next, the fixing nut is rotated to create a threaded connection with the fixing rod, thus limiting the movement of the steel chain and facilitating easy adjustment of the spacing between layers.

[0027] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 5 As shown, a silkworm rearing frame according to the first aspect embodiment of this application includes: a mounting frame 1, a fixing plate 7 and a fixing rod 10. A winding assembly is provided at the middle of the upper end of the mounting frame 1. Multiple sets of placement racks 5 are provided on the inner side of the mounting frame 1. A bottom plate 6 is installed on the bottom of the inner side of the placement rack 5.

[0029] The winding assembly includes a geared motor 2, a drive shaft 3, and winding reels 4. The geared motor 2 is mounted at the top center of the mounting frame 1, and its output end is connected to the drive shaft 3. Multiple winding reels 4 are fixedly mounted on the middle of the drive shaft 3, with each winding reel 4 corresponding to a steel rope 9. This allows the geared motor 2 to drive the drive shaft 3 and winding reels 4 to rotate synchronously, facilitating the winding of the steel rope 9 through the winding reels 4, thereby achieving the purpose of adjusting the height of multiple placement frames 5.

[0030] Meanwhile, the bottom of the placement rack 5 is hollowed out and has multiple sets of crossbars to facilitate the support of the base plate 6, so as to place multiple silkworm trays or silkworm platforms. The base plate 6 can also be a grid to improve ventilation and help improve air circulation.

[0031] Multiple placement racks 5 are fixedly installed with fixing plates 7 on both the left and right sides. A guide wheel 8 is fixedly installed on the outer side of the upper end of a set of fixing plates 7, and a steel rope 9 is provided on the outer side of the guide wheel 8. The steel rope 9 is wound around the outer side of the middle part of the winding reel 4.

[0032] Among them, the upper outer side of the multiple sets of fixing plates 7 are all fixedly installed with mounting rings 13, which facilitates the fixing of guide wheels 8 and mounting rings 13 through fixing plates 7 respectively. The top of the mounting frame 1 is also equipped with guide wheels 8, so that guide wheels 8 guide steel rope 9, making it easy for steel rope 9 to be smoothly wound onto the winding reel 4.

[0033] The upper end of the fixing plate 7 is lower than the top of the placement rack 5, and the longitudinal section of the fixing plate 7 is "L" shaped. A fixing rod 10 is fixedly installed on the lower outer side of the fixing plate 7, and a steel chain 11 is sleeved on the outer side of the fixing rod 10.

[0034] The fixing rod 10 is located directly above the mounting ring 13, and the mounting ring 13 is connected to the lower end of the steel chain 11. This allows the steel chain 11 to be installed in the gap between the two sets of placement frames 5 through the fixing rod 10 and the mounting ring 13, so that one set of steel chains 11 can move between two adjacent sets of placement frames 5. This facilitates the movement of multiple sets of placement frames 5 by sequentially driving multiple sets of steel chains 11.

[0035] Meanwhile, the outer side of the fixing rod 10 is threaded, and a fixing nut 12 located outside the steel chain 11 is installed on the outer side of the fixing rod 10 to prevent the steel chain 11 from falling off. The top of the steel chain 11 can slide on the outer side of the fixing rod 10 to allow multiple sets of placement racks 5 to be stably stacked sequentially. When the placement rack 5 moves downward to the lowest point, the ring sleeved on the outer side of the fixing rod 10 can move upward to the lowest point, and at the same time, the ring sleeved on the outer side of the mounting ring 13 can rotate outward to prevent the steel chain 11 from affecting the stacking of the placement racks 5.

[0036] A limiting block 14 is fixedly installed on the side wall of the placement rack 5, and the limiting block 14 is slidably connected to the mounting frame 1 to limit the movement of the placement rack 5 and prevent the placement rack 5 from deviating when moving.

[0037] Working principle

[0038] First, the entire unit is moved to the designated position using the braked casters. Then, the silkworm trays or silkworm beds are placed sequentially into the placement rack 5. When feeding silkworms and removing sand, the reduction motor 2 is activated via the control panel mounted on the front right side of the upright frame 1. This motor drives the drive shaft 3 and the winding reel 4 to rotate, facilitating the winding of the steel rope 9. This, in turn, moves the first layer of placement rack 5 upwards to a comfortable operating height for the worker. At this point, the worker can perform feeding and sand removal operations on the first layer. As the first layer of placement rack 5 moves upwards, the steel chain 11 between the first and second layers is pulled vertically, thus moving the second layer of placement rack 5 upwards to a comfortable operating height for the worker. Similarly, multiple sets of placement racks 5 are moved upwards sequentially, reaching comfortable operating heights for the worker. This effectively reduces the need for frequent bending and movement, lowers labor intensity, and improves work efficiency.

[0039] When it is necessary to adjust the spacing between the placement racks 5, the fixing nut 12 can be rotated to separate it from the fixing rod 10. Then, the ring connecting the steel chain 11 to the fixing rod 10 can be removed, and the ring at a suitable length on the steel chain 11 can be fitted onto the outside of the fixing rod 10. Then, the fixing nut 12 can be rotated to make it threadedly connected to the fixing rod 10, thereby limiting the movement of the steel chain 11 and facilitating the adjustment of the spacing between layers.

[0040] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
