Description

Technical Field

[0001] This invention relates to the field of silkworm rearing equipment technology, specifically a layered silkworm rearing device. Background Technology

[0002] The stacked silkworm rearing device is a new type of silkworm rearing equipment. Its design and application aim to improve the efficiency of silkworm rearing and save space. It mainly consists of a base frame, a top frame, and columns. Multiple sets of mulberry leaf layers and silkworm cocoon layers are set on the columns. The multiple sets of mulberry leaf layers are used to place mulberry leaves and cultivate silkworms. After the silkworms grow up, the silkworm cocoon layer needs to be moved downward by a lifting mechanism to contact the mulberry leaves, so that the silkworms can climb onto the silkworm cocoon layer. Then, the silkworm cocoon layer is raised upward by the lifting mechanism and then limited by a pin.

[0003] However, in existing tiered silkworm rearing devices, the existing lifting mechanism is mainly driven by a motor to rotate a rod. The rod then winds up or unwinds the pull rope to raise or lower the cocoon-forming layers. However, this requires changing the position of the pull rope multiple times to raise or lower each cocoon-forming layer, making it inconvenient and slow to use. Furthermore, the pins used to limit the cocoon-forming layers are also not convenient and quick enough, further complicating the operation and affecting the efficiency of silkworm rearing. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing a layered silkworm rearing device. Existing layered silkworm rearing devices primarily use a motor-driven rotating rod to raise or lower the silkworm cocooning layers by winding or unwinding the pull rope. However, this requires repeatedly changing the position of the pull rope to raise or lower each layer, making it inconvenient and slow. Furthermore, the use of pins to limit the movement of the silkworm cocooning layers is also inconvenient and slow, further hindering the efficiency of silkworm rearing. 。

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: ： A stacked silkworm rearing device includes a base frame, a top frame, and columns mounted on a stacked frame body. The side walls of the columns are provided with multiple silkworm rearing mechanisms arranged in an array, and each silkworm rearing mechanism includes a mulberry leaf layer and a silkworm cocoon layer. The mulberry leaf layer is fixed to the side walls of the columns, and the silkworm cocoon layer is slidably connected to the side walls of the columns. The side walls of the columns are provided with a limiting mechanism for limiting the silkworm cocoon layer, and the top of the top frame is provided with a pulling mechanism for raising and lowering the silkworm cocoon layer.

[0006] The pulling mechanism includes two sets of symmetrically arranged fixed plates fixedly connected to the top of the top frame, with two plates in each set. A rotating rod is rotatably connected to the opposite sidewall of each set of fixed plates, and a transmission mechanism is provided between the two rotating rods. A motor is fixedly connected to the sidewall of one of the fixed plates, and the output end of the motor is fixed to one end of the rotating rod. Multiple sets of arrayed winding rollers are sleeved on the sidewalls of the two rotating rods, with two winding rollers in each set. Two symmetrically arranged connecting blocks are fixedly connected to the sidewall of each cocoon layer, and a pull rope is fixedly connected to the top of each connecting block. The upper end of the pull rope is wound around the sidewall of the winding roller, and a connecting mechanism is provided between each winding roller and the rotating rod.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the rotating mechanism includes an L-shaped plate fixedly connected to the top of the top frame, and a fixing ring is fixedly connected to the side wall of each L-shaped plate. A rubber ring is fixedly connected to the inner side wall of each fixing ring, and the winding roller is rotatably connected to the inner side wall of the rubber ring.

[0009] The beneficial effect of adopting the above-mentioned further solution is that it ensures the normal rotation of the winding roller, and at the same time, the winding roller will not rotate arbitrarily when the connecting mechanism is disconnected and the rotating rod does not rotate.

[0010] Furthermore, the connecting mechanism includes multiple slots arranged in an array on the side wall of the rotating rod, and the ends of each winding roller are connected to insert blocks through a first moving mechanism.

[0011] The beneficial effect of adopting the above-mentioned further solution is that when the motor is started, the rotation of the motor drives the rotation of the rotating rod, and through the transmission mechanism, it drives another rotating rod to rotate. At the same time, when the rotating rod rotates, it can drive the winding roller to rotate through the connecting mechanism, thereby loosening or winding the pull rope, and thus realizing the descent and rise of a certain silkworm cocoon layer.

[0012] Furthermore, the first moving mechanism includes a support block fixedly connected to the end of each winding roller, and a T-shaped guide rod is inserted into the top of the support block. A guide strip is fixedly connected to the side wall of the T-shaped guide rod, and a moving disk is fixedly connected to the lower end of the T-shaped guide rod. The insertion block is fixed to the bottom of the moving disk, and a first spring is sleeved on the side wall of each T-shaped guide rod. A first iron block is fixedly connected to the end of the moving disk, and a first electromagnet is fixedly connected to the side wall of the support block.

[0013] The beneficial effect of adopting the above-mentioned further solution is that when the two first electromagnets of a certain group are de-energized, the moving disk and the insert block move downward under the action of the first spring, and the insert block is inserted into the slot. When the rotating rod rotates, it can drive the winding roller to rotate through the connecting mechanism.

[0014] Furthermore, the limiting mechanism includes limiting blocks fixedly connected to the side walls of each cocoon layer, and multiple arrayed mounting blocks are fixedly connected to the side walls of the column. The side walls of the mounting blocks are provided with sliding grooves, and sliding plates are slidably connected to the sliding grooves through a second moving mechanism.

[0015] Furthermore, the sidewall of the sliding plate is fixedly connected with a plurality of arrayed triangular blocks, and the triangular blocks include inclined surfaces and limiting surfaces.

[0016] The beneficial effect of adopting the above-mentioned further solution is that when the silkworm cocoon layer moves downward, the second moving mechanism causes the triangular block to slide into the sliding groove. At this time, the triangular block disengages from the limiting block, ensuring that the silkworm cocoon layer can move downward normally. After the silkworms have completely climbed onto the silkworm cocoon layer, the second moving mechanism causes the triangular block to extend outward. Then, the silkworm cocoon layer is moved upward. At this time, the limiting block slides along the inclined plane, thereby pushing the triangular block to move into the sliding groove. When it moves to a suitable height, the triangular block can extend outward under the action of the second moving mechanism and make the limiting surface abut against the side wall of the limiting block, thus limiting the silkworm cocoon layer. This makes it easier and faster to use, improving the efficiency of silkworm rearing.

[0017] Furthermore, the second moving mechanism includes a notch at the top of the sliding groove, and a second iron block is inserted into the notch, the second iron block being fixed to the top of the sliding plate.

[0018] Furthermore, a second electromagnet is fixedly connected to the top of the mounting block, and a second spring is fixedly connected between the sliding plate and the sliding groove.

[0019] The beneficial effect of adopting the above-mentioned further solution is that when the second electromagnet is energized, it attracts the second iron block, causing the triangular block to slide into the sliding groove. At the same time, the second spring is compressed, de-energizing the second electromagnet, and the triangular block can extend outward under the action of the second spring.

[0020] Furthermore, the transmission mechanism includes two symmetrically arranged pulleys fixedly sleeved on the side walls of the two rotating rods, and belts are sleeved on the side walls of the two pulleys.

[0021] The beneficial effect of adopting the above-mentioned further solution is that when the motor is started, the rotation of the motor drives the rotation of the rotating rod. When the rotating rod rotates, it drives one of the pulleys to rotate, and through the belt and the other pulley, it drives the other rotating rod to rotate.

[0022] The beneficial effects of this invention are:

[0023] 1. Fully Automated and High-Efficiency Layered Silkworm Rearing System: This invention's layered silkworm rearing device achieves a high degree of automation and intelligence in the silkworm rearing process. Through an integrated motor drive system and a precisely designed transmission mechanism, it can be started with a single button, simultaneously driving the lifting and lowering of multiple cocoon-forming layers. The innovative electromagnet and spring linkage mechanism automatically switches working states, eliminating the need for frequent manual changes of the pull rope position or manual pin insertion, greatly simplifying the operation process and achieving seamless connection and separation between the cocoon-forming layer and the mulberry leaf layer. This process not only improves operational efficiency but also significantly reduces labor costs.

[0024] 2. Intelligent Precision Limiting Technology: To further enhance the safety and stability of the equipment, this invention innovatively introduces an intelligent precision limiting mechanism. When the silkworm cocoon layer automatically descends according to a preset program and contacts the mulberry leaves, the intelligent control of the second electromagnet ensures the immediate response of the limiting mechanism, allowing the cocoon layer to pass smoothly. When the cocoon layer needs to rise and be fixed in position, the limiting mechanism automatically locks itself through the precise cooperation of the electromagnet and the spring, ensuring the cocoon layer remains stable and does not wobble. This technology not only improves the stability of equipment operation but also avoids errors that may be caused by improper manual operation, truly realizing intelligent and precise control of the silkworm rearing process and showcasing the infinite possibilities of future intelligent agricultural development.

[0025] 3. The stacked silkworm rearing device of the present invention, with its fully automated and efficient operation process and intelligent and precise limiting technology, not only greatly improves the efficiency and yield of silkworm rearing, but also leads the new trend of modern agriculture towards automation and intelligence, injecting strong impetus into the development of the silkworm industry.

Detailed Implementation

[0037] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0038] The stacked silkworm rearing device is a new type of silkworm rearing equipment. Its design and application aim to improve the efficiency of silkworm rearing and save space. It mainly consists of a base frame, a top frame, and columns. Multiple sets of mulberry leaf layers and silkworm cocoon layers are set on the columns. The multiple sets of mulberry leaf layers are used to place mulberry leaves and cultivate silkworms. After the silkworms grow up, the silkworm cocoon layer needs to be moved downward by a lifting mechanism to contact the mulberry leaves, so that the silkworms can climb onto the silkworm cocoon layer. Then, the silkworm cocoon layer is raised upward by the lifting mechanism and then limited by a pin.

[0039] After conducting in-depth investigation and research on the use of the stacked silkworm rearing device, the inventors discovered that the existing stacked silkworm rearing device mainly uses a motor to drive a rotating rod to rotate, which in turn winds up or unwinds the pull rope to raise or lower the silkworm cocoon layer. However, in use, it is necessary to change the position of the pull rope multiple times to raise or lower each silkworm cocoon layer, which is not convenient and quick. Furthermore, the use of pins to limit the silkworm cocoon layer is also not convenient and quick, making the use inconvenient and slow, and affecting the efficiency of silkworm rearing.

[0040] The aforementioned problems have not been publicly reported in this field. The inventors discovered the aforementioned problems and designed this technical solution.

[0041] The present invention provides the following preferred embodiments.

[0042] like Figures 1-9 As shown, a stacked silkworm rearing device includes a base frame 101, a top frame 102, and a column 103 mounted on a stacked frame body 1. The side wall of the column 103 is provided with a plurality of silkworm rearing mechanisms arranged in an array, and each silkworm rearing mechanism includes a mulberry leaf layer 801 and a silkworm cocoon layer 802. The mulberry leaf layer 801 is fixed to the side wall of the column 103, and the silkworm cocoon layer 802 is slidably connected to the side wall of the column 103. The side wall of the column 103 is provided with a limiting mechanism for limiting the silkworm cocoon layer 802, and the top of the top frame 102 is provided with a pulling mechanism for raising and lowering the silkworm cocoon layer 802.

[0043] The pulling mechanism includes two sets of symmetrically arranged fixed plates 901 fixedly connected to the top of the top frame 102, with two plates in each set. Rotating rods 902 are rotatably connected to the opposite side walls of each set of fixed plates 901, and a transmission mechanism is provided between the two rotating rods 902. A motor 903 is fixedly connected to the side wall of one of the fixed plates 901, and the output end of the motor 903 is fixed to one end of the rotating rod 902. Multiple arrayed winding rollers 904 are sleeved on the side walls of the two rotating rods 902. There are two of the 4. Each cocoon layer 802 has two symmetrically arranged connecting blocks 905 fixedly connected to its side wall. Each connecting block 905 has a pull rope 906 fixedly connected to its top. The upper end of the pull rope 906 is wound around the side wall of the winding roller 904. Each winding roller 904 and the rotating rod 902 are connected by a connecting mechanism. There is no need to change the position of the pull rope 906, which makes it easy to lower and raise the cocoon layer 802. At the same time, it is easy to limit the position of the cocoon layer 802, making it more convenient and faster to use and improving the efficiency of silkworm rearing.

[0044] In this embodiment, as Figure 7 As shown, the rotating mechanism includes an L-shaped plate 201 fixedly connected to the top of the top frame 102, and a fixing ring 202 is fixedly connected to the side wall of each L-shaped plate 201. A rubber ring 203 is fixedly connected to the inner side wall of each fixing ring 202, and the winding roller 904 is rotatably connected to the inner side wall of the rubber ring 203 to ensure the normal rotation of the winding roller 904. At the same time, when the connecting mechanism is disconnected and the rotating rod 902 does not rotate, the winding roller 904 will not rotate arbitrarily.

[0045] In this embodiment, as Figure 7 and Figure 8As shown, the connecting mechanism includes multiple slots 301 arranged in an array on the side wall of the rotating rod 902, and the ends of each winding roller 904 are connected to insert blocks 302 through a first moving mechanism. When the motor 903 is started, the rotation of the motor 903 drives the rotation of the rotating rod 902, and drives another rotating rod 902 to rotate through the transmission mechanism. At the same time, when the rotating rod 902 rotates, it can drive the winding roller 904 to rotate through the connecting mechanism, thereby loosening or winding the pull rope 906, thereby realizing the descent and rise of a certain cocoon layer 802.

[0046] In this embodiment, as Figure 8 As shown, the first moving mechanism includes a support block 401 fixedly connected to the end of each winding roller 904, and a T-shaped guide rod 402 is inserted into the top of the support block 401. A guide strip 403 is fixedly connected to the side wall of the T-shaped guide rod 402, and a moving disk 404 is fixedly connected to the lower end of the T-shaped guide rod 402. An insert block 302 is fixed to the bottom of the moving disk 404, and a first spring 405 is sleeved on the side wall of each T-shaped guide rod 402. A first iron block 407 is fixedly connected to the end of the moving disk 404, and a first electromagnet 406 is fixedly connected to the side wall of the support block 401. When the two first electromagnets 406 in a certain group are de-energized, the moving disk 404 and the insert block 302 move downward under the action of the first spring 405, and the insert block 302 is inserted into the slot 301. When the rotating rod 902 rotates, it can drive the winding roller 904 to rotate through the connecting mechanism.

[0047] In this embodiment, as Figure 2 and Figure 4As shown, the limiting mechanism includes limiting blocks 601 fixedly connected to the side walls of each cocooning layer 802, and multiple arrayed mounting blocks 607 fixedly connected to the side wall of the column 103. The side wall of each mounting block 607 has a sliding groove 602, and a sliding plate 603 is slidably connected to the sliding groove 602 via a second moving mechanism. Multiple arrayed triangular blocks 604 are fixedly connected to the side wall of the sliding plate 603, and each triangular block 604 includes an inclined surface 605 and a limiting surface 606. When the cocooning layer 802 moves downward, the second moving mechanism causes the triangular blocks 604 to slide into the sliding groove 602. At this time, the triangular blocks 604 disengage from the limiting blocks 601. To ensure the cocooning layer 802 can move downwards normally, once the silkworms have completely climbed onto the cocooning layer 802, the second moving mechanism causes the triangular block 604 to extend outwards. Then, the cocooning layer 802 is moved upwards. At this time, the limiting block 601 slides along the inclined plane 605, thereby pushing the triangular block 604 into the sliding groove 602. When it moves to a suitable height, the triangular block 604 can extend outwards under the action of the second moving mechanism, causing the limiting surface 606 to abut against the side wall of the limiting block 601, thus limiting the cocooning layer 802. This makes it easier and faster to use the cocooning layer 802, improving the efficiency of silkworm rearing.

[0048] In this embodiment, as Figure 4 As shown, the second moving mechanism includes a notch 701 opened at the top of the sliding groove 602, and a second iron block 702 is inserted into the notch 701. The second iron block 702 is fixed to the top of the sliding plate 603, and a second electromagnet 703 is fixedly connected to the top of the mounting block 607. A second spring 704 is fixedly connected between the sliding plate 603 and the sliding groove 602. When the second electromagnet 703 is energized, it attracts the second iron block 702, causing the triangular block 604 to slide into the sliding groove 602. At the same time, the second spring 704 is compressed, de-energizing the second electromagnet 703, and the triangular block 604 can extend outward under the action of the second spring 704.

[0049] In this embodiment, as Figure 3 and Figure 6 As shown, the transmission mechanism includes two symmetrically arranged pulleys 501 fixedly sleeved on the side walls of two rotating rods 902, and belts 502 are sleeved on the side walls of the two pulleys 501. When the motor 903 is started, the rotation of the motor 903 drives the rotation of the rotating rods 902. When the rotating rods 902 rotate, they drive one of the pulleys 501 to rotate, and through the belts 502 and the other pulley 501, they drive the other rotating rod 902 to rotate.

[0050] The specific working process of this invention is as follows:

[0051] First, when raising silkworms, mulberry leaves are placed in the mulberry leaf layer 801, and silkworm eggs are scattered on the mulberry leaves. After the silkworm eggs hatch, the larvae feed on the mulberry leaves to grow and develop. After the larvae grow up, the motor 903 is started. The rotation of the motor 903 drives the rotation of the rotating rod 902, and through the transmission mechanism, it drives another rotating rod 902 to rotate. At the same time, the two first electromagnets 406 in a certain group are de-energized. At this time, under the action of the first spring 405, the moving disk 404 and the insertion block 302 move downward and insert the insertion block 302 into the slot 301. When the rotating rod 902 rotates, it can drive the winding roller 904 to rotate through the connecting mechanism, thereby loosening the pull rope 906.

[0052] At the same time, the second electromagnet 703 is energized. After the second electromagnet 703 is energized, it attracts the second iron block 702, causing the triangular block 604 to slide into the sliding groove 602. At the same time, the second spring 704 is compressed. At this time, the triangular block 604 is disengaged from the limiting block 601, ensuring that the cocoon layer 802 can move downward normally.

[0053] At this time, under the action of gravity, the cocoon layer 802 moves downward and comes into contact with the mulberry leaves on the mulberry leaf layer 801. At this time, the silkworm will climb onto the cocoon layer 802. After climbing, the second electromagnet 703 is de-energized, and the triangular block 604 can extend outward under the action of the second spring 704. Then, the motor 903 is started to reverse, so that the pull rope 906 is wound up by the winding roller 904, thereby pulling the cocoon layer 802 upward. At this time, the limiting block 601 slides along the inclined plane 605, thereby pushing the triangular block 604 to move into the sliding groove 602. At the same time, the second spring 704 is compressed. When it moves to a suitable height, the triangular block 604 can extend outward under the action of the second spring 704 and make the limiting surface 606 abut against the side wall of the limiting block 601, which can limit the cocoon layer 802, making it easier to limit the cocoon layer 802. This makes it more convenient and faster to use and improves the efficiency of silkworm rearing.

[0054] Furthermore, when the device is moved to a suitable height, the first electromagnet 406 is energized, thereby attracting the moving disk 404 and the insert block 302 to move upward and exit from the slot 301. At the same time, the first spring 405 is compressed, causing the two winding rollers 904 of this group to disconnect from the rotating rod 902. Similarly, the cocooning layers 802 of other silkworm rearing mechanisms can be lowered and raised without changing the position of the pull rope 906, making it easier and faster to lower and raise the cocooning layers 802, thus improving the efficiency of silkworm rearing.

[0055] In summary, the beneficial effects of this invention are specifically reflected in the fact that there is no need to change the position of the pull rope 906, which facilitates the lowering and raising of the silkworm cocoon layer 802. At the same time, it is convenient to limit the position of the silkworm cocoon layer 802, making it more convenient and faster to use and improving the efficiency of silkworm rearing.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
