Description

Technical Field

[0001] The utility model belongs to the technical field of sericulture equipment, relates to a sericulture table, and particularly relates to a lifting sericulture table which is convenient to adjust the height and operate. Background Technique

[0002] As a traditional industry in China, the sericulture industry has a long history and has a profound impact on the global silk culture and trade. With the passage of time, sericulture technology has been continuously improving, gradually developing from the initial small-scale manual sericulture at home to intensive and large-scale development. However, despite the development of sericulture technology, there are still many inconveniences and limitations in the key facility of the sericulture table, which restricts the sericulture efficiency and the pace of industrial modernization.

[0003] At present, the structure of the sericulture table generally adopts a multi-layer frame stacking method, and the columns are connected by bolts to support the frame. Although this design meets the basic needs of sericulture to a certain extent, its fixed height and cumbersome adjustment method make it particularly inconvenient during the sericulture process, especially when it is necessary to adjust the sericulture table to adapt to silkworms at different growth stages. In addition, the multi-layer stacked frames also bring difficulties to the staff in dealing with sericulture on the upper or lower layers.

[0004] In order to overcome the limitations of the existing sericulture table, some technical improvement attempts have been made in the industry. For example, the electric lifting sericulture table proposed in the prior art realizes the lifting function of the sericulture table through an electric method, improving the convenience of operation. However, this design still has deficiencies when the large silkworms are mounting the cocooning frame. Especially when it is necessary to combine the sericulture tables and install the rotary frame for silk spinning and cocooning operations, the existing structure limits the working height and affects the work efficiency of the operators. During the sericulture process, especially during the stage when the large silkworms are mounting the cocooning frame, it is necessary to combine two layers of silkworms onto one sericulture table and install a rotary frame to facilitate the silkworms to spin silk and form cocoons. However, since the height between the installation layers of the rotary frame is not fixed, if there is a misoperation during the adjustment of the electric lifting sericulture table, resulting in the incorrect reduction of the height between the layers, it may cause harm to the silkworms, and at the same time, the rotary frame may also be damaged. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a new type of safe lifting sericulture table. On the basis of maintaining the convenience of electric lifting, this sericulture table reduces the operation risk through innovative design to ensure safety during the installation of the rotary frame or other sericulture operations.

[0061] The following is described in conjunction with the accompanying drawings and a specific embodiment.

[0062] To make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model.

[0063] It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0064] See Figures 1 to 6 This embodiment describes a lifting silkworm platform, which includes a bed frame 100, multiple layers of silkworm platforms and a driving device 200.

[0065] The bed frame 100 is a frame structure, welded or bolted together by strong metal materials, providing a support foundation for the entire lifting silkworm platform. The bed frame 100 is designed with multiple support points to ensure stability and load-bearing capacity during the lifting process. The bed frame 100 also serves as a guide rail for the lifting of the silkworm platform.

[0066] The multiple layers of silkworm platforms are installed on the bed frame 100. Each layer of the silkworm platform is designed with a bottom cloth or net for placing mulberry silkworms. These silkworm platforms are alternately connected by fixed connecting plates 400 and adjusting members 500 to form a hierarchical structure. The fixed connecting plates 400 ensure a fixed distance between adjacent silkworm platforms, while the adjusting members 500 allow the distance between adjacent silkworm platforms to be adjusted when needed.

[0067] The driving device 200 is installed on the bed frame 100, usually located on one side or in the middle of the bed frame 100 for easy maintenance and operation. The driving device 200 includes at least one servo motor or stepper motor, which, through precise control, drives the transmission mechanism to realize the lifting of the silkworm platform. The transmission mechanism includes a transmission belt 310, a reel 320, a traction assembly 330, a fixed pulley 340 and a movable pulley 350. The transmission belt 310 connects the driving device 200 and the reel 320, and the reel 320 winds and unwinds the traction assembly 330. One end of the traction assembly 330 is fixedly connected to the reel 320, and the other end passes through the fixed pulley 340 and the movable pulley 350 and is then fixedly connected to the ejector rod 101 on the bed frame 100. The operator can start the driving device 200 through the control panel. The motor rotates to drive the reel 320 to rotate, and the traction assembly 330 transmits power through the transmission belt 310 to realize the lifting of multiple layers of silkworm platforms.

[0068] According to an embodiment of the silkworm platform lifting of the present utility model, a shaft hole 410 is provided on the fixed connecting plate 400, and a rotating shaft 600 is detachably installed on the shaft hole 410, and a rotary frame is installed on the rotating shaft 600. The fixed connecting plate 400 is a key connecting component in the silkworm platform lifting, and the number is several, for example, 4, which are distributed on both sides of the silkworm platform to ensure a uniform fixed spacing between each layer of silkworm platforms. On each shaft hole 410, the rotating shaft 600 is fixed by a detachable installation method. The rotating shaft 600 is usually made of high-strength metal material to bear the gravity of the rotary frame and the silkworms. The rotating shaft 600 and the shaft hole 410 can be fixed by fasteners such as bolts and nuts for easy installation and future maintenance. Alternatively, a bearing 420 can also be installed on the shaft hole 410, and the rotating shaft 600 is detachably installed on the bearing 420.

[0069] The adjusting member 500 is a key component for adjusting the layer spacing of the silkworm platform in the silkworm platform lifting, and is composed of three main parts: an upper ring 510, a hanging plate 520 and a lower ring 530. According to an embodiment of the silkworm platform lifting of the present utility model, the adjusting member 500 includes an upper ring 510, a hanging plate 520 and a lower ring 530.

[0070] The upper ring 510 is designed to be fixedly connected to the upper silkworm platform. Usually, the upper ring 510 is connected to the frame structure of the silkworm platform by welding, bolts or special fasteners to ensure stability and load-bearing capacity during the lifting process.

[0071] The lower ring 530 is made of a flexible material, such as a steel wire rope, a nylon rope or other flexible but high-strength materials, to allow the lower ring 530 to remain slack when not in use and be able to stretch to adjust the layer spacing when in use. The lower ring 530 is fixedly connected to the lower silkworm platform, usually through an adjustable fixing device, such as a hook ring, a buckle or other quick connection mechanisms, for easy and quick adjustment of the distance between the silkworm platforms.

[0072] The hanging plate 520 is fixedly connected to the upper ring 510 and the lower ring 530. The hanging plate 520 is a plate made of a rigid material and is connected to the silkworm platform below the adjusting member 500. The hanging plate 520 can be connected to the silkworm platform below the adjusting member 500 through a hook, a clamp or other mechanical devices, so as to realize the superposition of the silkworm platforms above and below the adjusting member 500 and reduce the overall height of the multi-layer silkworm platforms.

[0073] According to an embodiment of the silkworm platform lifting device of the present invention, the transmission mechanism includes a transmission belt 310, a reel 320, a traction assembly 330, a fixed pulley 340 and a movable pulley 350. The transmission belt 310 is used for transmitting power. The reel 320 is wound with the transmission belt 310 and is responsible for taking in and releasing the traction assembly 330. A top rod 101 is provided on the bed frame 100, and the traction assembly 330 connects the reel 320 and the top rod 101 to transmit the traction force. The fixed pulley 340 is installed on the top rod 101 of the bed frame 100 to change the traction direction of the traction assembly 330. The movable pulley 350 interacts with the traction assembly 330 to reduce the load on the reel 320.

[0074] The reel 320 is installed at an appropriate position on the bed frame 100, usually close to the driving device 200. In this embodiment, the reel 320 is installed in the middle of the top of the bed frame 100, and the rotation of the reel 320 is driven by the driving device 200 through the transmission belt 310 to realize the taking in and releasing of the traction assembly 330.

[0075] The first end of the traction assembly 330 is fixedly connected to the reel 320 to ensure the effective transmission of power. The first end of the traction assembly 330 is fixedly connected to the reel 320, the second end passes through the fixed pulley 340, passes downward through the movable pulley 350, and then is fixedly connected to the top rod 101 upward. The material selection of the traction assembly 330 needs to consider strength and durability, and commonly used steel wire ropes or synthetic fiber ropes are used.

[0076] The fixed pulley 340 is installed on the top rod 101 of the bed frame 100, and its position and design ensure that the traction assembly 330 can smoothly change the direction and reduce the friction loss. The movable pulley 350 is arranged on the path of the traction assembly 330. When the traction assembly 330 passes through the movable pulley 350, the required traction force can be reduced and the mechanical efficiency of the system can be improved.

[0077] After the second end of the traction assembly 330 passes through the fixed pulley 340, it passes downward through the movable pulley 350, and then is fixedly connected to the top rod 101 upward again, forming a transmission path to ensure the stable transmission of the traction force. The operator controls the driving device 200 to drive the rotation of the reel 320, and the traction assembly 330 is taken in and released accordingly. Through the cooperation of the fixed pulley 340 and the movable pulley 350, the smooth lifting and lowering of the multi-layer silkworm platforms are realized.

[0078] According to an embodiment of the lifting mulberry silkworm platform of the present utility model, the lifting mulberry silkworm platform is designed to include six levels of mulberry silkworm platforms, which are the first mulberry silkworm platform 110, the second mulberry silkworm platform 120, the third mulberry silkworm platform 130, the fourth mulberry silkworm platform 140, the fifth mulberry silkworm platform 150, and the sixth mulberry silkworm platform 160 from top to bottom. On the first mulberry silkworm platform 110, a movable pulley bracket 111 is specially installed. The structural design of the movable pulley bracket 111 should ensure sufficient strength and stability to support the weight of the upper mulberry silkworm platform and reduce friction during the lifting process. The movable pulley 350 is installed on the movable pulley bracket 111, and its position and design allow the traction assembly 330 to smoothly change direction when passing through and reduce the required traction force. The use of the movable pulley 350 not only reduces the load on the reel 320 but also improves the efficiency of the entire lifting system. During the operation of the lifting mulberry silkworm platform, the movable pulley 350 allows the traction assembly 330 to lift the mulberry silkworm platform with a smaller force.

[0079] See Figure 5 and Figure 6 , according to an embodiment of the lifting mulberry silkworm platform of the present utility model, the second mulberry silkworm platform 120 and the fourth mulberry silkworm platform 140 are designed with connecting ears 102. The connecting ears 102 are protruding components located at the edges of the mulberry silkworm platforms and are used for fixedly connecting with the adjusting member 500. The shape and size of the connecting ears 102 are designed to ensure matching with the upper ring 510 of the adjusting member 500 and enable a stable connection. The third mulberry silkworm platform 130 and the fifth mulberry silkworm platform 150 are configured with hooks 103 and connection holes 104. The hooks 103 are quickly connected and separated from the hanging plate 520 of the adjusting member 500. The connection holes 104 are holes fixed at the edges of the mulberry silkworm platforms and are used for fixedly connecting with the lower ring 530 of the adjusting member 500. The hanging plate 520 of the adjusting member 500 is detachably connected with the hooks 103 of the third mulberry silkworm platform 130 and the fifth mulberry silkworm platform 150. This connection method allows for quick installation and removal of the hanging plate 520, facilitating the adjustment of the spacing between the mulberry silkworm platforms according to the needs of raising silkworms. The connection holes 104 play a connecting role on the third mulberry silkworm platform 130 and the fifth mulberry silkworm platform 150 and cooperate with the lower ring 530 of the adjusting member 500 to provide the maximum spacing between the mulberry silkworm platforms.

[0080] According to an embodiment of the lifting mulberry silkworm platform of the present utility model, the first mulberry silkworm platform 110 and the second mulberry silkworm platform 120, the third mulberry silkworm platform 130 and the fourth mulberry silkworm platform 140, the fifth mulberry silkworm platform 150 and the sixth mulberry silkworm platform 160 are respectively fixedly connected through fixed connection plates 400 to form a stable interlayer structure. The design of the fixed connection plates 400 ensures that the connection between adjacent mulberry silkworm platforms is both stable and firm, and the layer spacing between the mulberry silkworm platforms is always maintained during the lifting process.

[0081] According to an embodiment of the lifting silkworm platform of the present utility model, the driving device 200 is a servo motor or a stepper motor. The servo motor is used for the driving device 200 due to its high response speed and precise speed control ability. It can start and stop quickly and provide stable torque output throughout the operating range, being suitable for occasions with frequent start-stop and precise control requirements. The stepper motor is used for the driving device 200 due to its high response speed and precise speed control ability. It can start and stop quickly and provide stable torque output throughout the operating range, being suitable for occasions with frequent start-stop and precise control requirements. The driving device 200 is installed at a stable part of the bed frame 100, located at the top of the bed frame 100. The motor is fixed in place through a mounting bracket and fasteners. In a preferred embodiment, the operation of the motor is controlled by a control system, which can be a PLC (programmable logic controller), a microcontroller, or other electronic control units. The control system receives operation instructions and precisely controls the rotation speed and direction of the motor to achieve the lifting of the silkworm platform. The operator sends instructions to the control system through a control panel or a remote control, and the control system then controls the servo motor or the stepper motor to work, driving the silkworm platform to lift through a transmission mechanism to reach the required position.
