Description

Technical Field

[0001] This utility model relates to the field of sericulture technology, specifically a silkworm tray. Background Technology

[0002] Silkworm rearing is an agricultural breeding process that requires high standards in terms of environment, time, and operational management. Silkworms need to be fed, cleaned, and have their trays changed regularly at different growth stages. To facilitate management, a grid-like trough is commonly used in silkworm farms as a container for silkworms. These troughs are typically made of lightweight plastic or bamboo woven boards, with a grid-like internal structure that evenly distributes the silkworms within the trough, promoting ventilation, humidity control, and feeding.

[0003] In actual aquaculture, a large number of square troughs need to be stacked in an orderly manner and transported or managed centrally. Therefore, silkworm tray carts are usually used to carry and move the square troughs. However, the carts currently in use are quite heavy when fully loaded with square troughs, making it extremely difficult to turn on the spot, especially in environments with high friction such as brick or cement floors. If a side handle is added to make pushing easier, the protruding structure of the multiple square troughs on each cart will affect the neat stacking of carts, easily leading to wasted space and interference with adjacent carts. In addition, the large turning torque on the spot can easily cause the silkworm tray cart to tilt or even tip over under heavy load due to uneven force.

[0004] Therefore, there is an urgent need for a silkworm spinning wheel to solve the above-mentioned technical defects. Utility Model Content

[0005] The purpose of this utility model is to provide a silkworm tray cart to solve the problems mentioned in the background art, such as the large overall weight of the currently used cart after being fully loaded with square slots, making it inconvenient to turn in place, and the fact that setting handles would affect the stacking and interfere with adjacent carts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a silkworm tray cart, comprising an upper frame and a lower frame, wherein the upper frame is mounted on the top of the lower frame, and the upper frame and the lower frame are welded together at their four corners by vertical beams. Fixing plates are connected to the four corners of the bottom of the lower frame, and grooves are provided on all four sides of the lower frame. A traction structure is provided in each set of grooves. The traction structure includes a mounting seat installed in the groove, a rotating shaft is rotatably connected inside the mounting seat, a torsion spring is provided between the rotating shaft and the mounting seat, a pull rope is sleeved in the middle section of the rotating shaft, and a pull ring is connected to the end of the pull rope.

[0007] As a further technical solution of this utility model, the upper shelf is welded with buckle posts around its perimeter, and each pull ring matches the size of the corresponding buckle post.

[0008] As a further technical solution of this utility model, the upper shelf and the lower shelf have the same structural dimensions, both being rectangular frames welded together from four sets of steel straight rods.

[0009] As a further technical solution of this utility model, the vertical beam adopts an "L" shaped steel structure, and the upper and lower shelves are connected by corner reinforcement.

[0010] As a further technical solution of this utility model, each of the fixing plates is connected to a wheel seat below it, the lower end of the wheel seat is equipped with a ball bearing, the outer ring of the ball bearing is fitted with a wheel housing, and the bottom of the wheel housing is connected to a roller.

[0011] As a further technical solution of this utility model, a spring rod is installed inside each wheel housing, and the spring rod is movably assembled above the corresponding roller to form a buffer structure.

[0012] As a further technical solution of this utility model, the rollers are provided in four sets, which are respectively arranged below the four corners of the lower shelf to form a four-wheel support.

[0013] As a further technical solution of this utility model, the roller is made of nitrile rubber material.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a traction structure consisting of a mounting base, a rotating shaft, a torsion spring, a pull rope, and a pull ring, manual and rapid traction can be achieved during the use of the silkworm tray cart without pushing or turning in place, which is particularly suitable for silkworm rearing workshops where multiple silkworm tray carts are transported in groups; when the traction function is not used, the pull rope can be automatically retracted under the action of the torsion spring, and the pull ring can be hooked onto the buckle column on the outside of the upper shelf, avoiding dragging and wear or tripping workers, without interfering with adjacent carts, and improving space utilization.

[0015] The stacking frame consists of an upper shelf, a lower shelf, and vertical beams with an "L" shaped steel structure. There is a ventilation gap between the two layers designed for the thickness of the silkworm trays. This can maintain a good ventilation environment when stacking multiple silkworm trays, reduce the risk of silkworm diseases caused by high temperature and humidity, and at the same time make the stacking of silkworm trays stable and not easy to tilt or slip, thus improving space utilization. It is suitable for centralized storage and unified management in medium and large-sized silkworm farms.

[0016] Equipped with ball bearings, spring rods, and nitrile rubber rollers, the silkworm tray can effectively absorb vibrations when passing over brick, cement, or simple soil surfaces, maintaining stable operation and preventing disturbance to the silkworms due to uneven ground.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides an embodiment of a silkworm tray cart, including an upper frame 1 and a lower frame 2. The upper frame 1 is installed on the top of the lower frame 2. The upper frame 1 and the lower frame 2 are welded together at their four corners by vertical beams 3. Fixing plates 4 are connected to the four corners of the bottom of the lower frame 2. Grooves 5 are provided on all four sides of the lower frame 2. A traction structure is provided in each set of grooves 5. The traction structure includes a mounting seat 14 installed in the groove 5. A rotating shaft 16 is rotatably connected inside the mounting seat 14. A torsion spring 15 is provided between the rotating shaft 16 and the mounting seat 14. A pull rope 6 is sleeved in the middle of the rotating shaft 16. A pull ring 7 is connected to the end of the pull rope 6. Buckle posts 8 are welded around the upper frame 1. Each pull ring 7 matches the size of the corresponding buckle post 8.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, grooves 5 are evenly distributed in the middle of the four sides of the lower shelf 2. Each set of grooves 5 is fixedly connected to a mounting base 14. A rotating shaft 16 is embedded in the mounting base 14. A torsion spring 15 is installed between the rotating shaft 16 and the mounting base 14, which can automatically rebound when not being tractioned. A pull rope 6 is sleeved in the middle of the rotating shaft 16. One end of the pull rope 6 extends out of the groove 5, and the end is fixed to a pull ring 7. When it is necessary to move or change the direction of the silkworm tray cart, the silkworm tray cart can be moved as a whole by external traction force. It is especially suitable for multiple carts to be used at the same time to transport and pass through the silkworm rearing room passage. When not in use, the pull rope 6 is automatically retracted. Silkworm farmers can hook the pull ring 7 onto the buckle post 8 welded to the outer periphery of the upper shelf 1 of the silkworm tray cart to avoid dragging and wear and tripping.

[0025] The upper shelf 1 and the lower shelf 2 have the same structural dimensions. Both are rectangular frames welded together from four sets of steel straight rods. The vertical beam 3 adopts an "L" shaped steel structure and is connected to the upper shelf 1 and the lower shelf 2 by corner reinforcement.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the upper shelf 1 and the lower shelf 2 are each composed of four sets of steel straight rods forming a frame. The two-layer structure is fixed vertically at the four corners by four sets of vertical beams 3. A certain gap structure is maintained between the upper and lower layers. The gap height is matched with the height of the silkworm trays. When placing the silkworm trays, it can fully ensure ventilation and air permeability, avoid silkworm diseases or death caused by stuffiness and humidity, facilitate temperature and humidity control of the silkworm rearing environment, facilitate stacking and storage of multiple carts, and prevent the silkworm tray carts from shifting and tipping over. The structure is simple but highly practical and suitable for use in large-scale intensive silkworm rearing bases.

[0027] Each fixed plate 4 is connected to a wheel seat 9 below it. A ball bearing 10 is installed at the lower end of the wheel seat 9. A wheel housing 11 is embedded in the outer ring of the ball bearing 10. A roller 12 is connected to the bottom of the wheel housing 11. A spring rod 13 is installed inside the wheel housing 11. The spring rod 13 is movably mounted above the corresponding roller 12 to form a buffer structure. There are four sets of rollers 12, which are respectively set below the four corners of the lower frame 2 to form a four-wheel support. The rollers 12 are made of nitrile rubber material.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the four corners of the bottom of the lower frame 2 are welded and fixed to the wheel seat 9 by fixing pieces 4. The bottom of the wheel seat 9 is rotatably connected to a ball bearing 10. The bottom of the wheel shell 11 is equipped with a roller 12. The roller 12 is made of wear-resistant nitrile rubber, which has good elasticity and ground adaptability. A spring rod 13 is set above each set of rollers 12. The spring rod 13 is located inside the wheel shell 11. It can buffer the uneven ground during the movement of the silkworm tray cart, reduce the disturbance of vibration to the silkworms, and ensure the stability of the silkworm tray stacking and the safety of transportation on paved brick, cement or simple dirt roads.

[0029] Working principle: This silkworm tray cart is used for stacking and transporting square troughs for silkworm rearing. When in use, silkworm rearing personnel place the square troughs filled with silkworm eggs or silkworms directly on the upper shelf 1. The upper shelf 1 is a frame structure welded from four sets of steel straight rods, forming an open platform. Its four corners are connected and fixed to the lower shelf 2 through four sets of "L"-shaped vertical beams 3. Each vertical beam 3 extends vertically upward and is located at the four corner edges of the upper shelf 1, forming a four-sided limiting effect, effectively preventing the square troughs from sliding or shifting during transportation or pushing, ensuring the stability and safety of the silkworm tray stacking. When it is necessary to move the silkworm tray cart, the pull rope 6 can be pulled out from the groove 5, and the pull ring 7 can be used for manual or mechanical traction to move the entire device. The bottom rollers 12 and the spring buffer structure can adapt to different ground surfaces, reduce the impact of bumps, and help protect the quiet growth environment of the silkworms.
