Description

Technical Field

[0001] This invention belongs to the field of agricultural automation equipment technology, and in particular relates to an automated breeding device for castor silkworms. Background Technology

[0002] In the breeding process of castor silkworms, the uniformity of castor leaf feeding, the efficiency of separating silkworm bodies from excrement / residual leaves, and the precise control of the breeding environment are the core factors that directly affect the uniformity of silkworm growth and development, health status, and final cocoon quality. However, existing castor silkworm breeding devices, especially in the automated feeding stage of castor leaves, have many technical bottlenecks that need to be solved:

[0003] Traditional castor leaf feeding relies heavily on extensive conveying methods (such as simple belt conveyors and manual scattering), which cannot control the amount of castor leaves conveyed and the uniformity of distribution. The overlapping castor leaves can easily block the conveying channels, and blank areas are likely to appear during the conveying process, resulting in uneven feeding of silkworms. Waste of residual leaves and hunger of some silkworms coexist, affecting the uniformity of silkworm growth and the quality of cocoon spinning. Summary of the Invention

[0004] This invention addresses the problems of traditional castor leaf feeding, which relies heavily on extensive conveying methods (such as simple belt conveyors and manual scattering). These methods fail to control the amount and uniformity of castor leaf distribution, easily clog conveying channels due to overlapping leaves, and create gaps in the conveying process. This results in uneven feeding by silkworms, waste of leaves, and hunger in some silkworms, negatively impacting the uniformity of silkworm growth and cocoon quality. The invention proposes the following technical solution:

[0005] The automated breeding device for castor silkworms includes:

[0006] Feed hood, used to guide castor leaves in;

[0007] Conveyor frame, connected below the feed hood;

[0008] The conveyor belt is located inside the conveyor frame and the feed hood;

[0009] The cultivation tank is located on the conveyor belt of the conveyor frame;

[0010] The castor leaf layering supplementary assembly includes: a pressing roller, located above the discharge end of the conveyor belt; a pushing roller, located at the front end of the pressing roller and rotating in the opposite direction to the pressing roller; a driving component, synchronously driving the pressing roller to rotate forward and the pushing roller to rotate in the opposite direction; a speed-changing structure, connecting the pushing roller and the pressing roller; a fan blade, located in the speed-changing structure; a gas collecting hood, located at one end of the fan blade and connected to the magnetic oscillation structure; a magnetic oscillation structure, located above the gas collecting hood and controlling the airflow direction; a converging hood, connected to one end of the gas collecting hood; cavities, separated within the converging hood; and jet pipes, corresponding to each cavity.

[0011] The pusher roller blocks the upper layer of the multi-layer castor leaves, and the single layer of castor leaves enters the cultivation tank through the pressing roller; the pressing roller drives the fan blades to generate airflow through the speed-changing structure, and the magnetic swing structure controls the airflow to alternately enter different cavities and then be ejected along the jet pipe, so that the multi-layer castor leaves enter the blank area at the top of the conveyor belt.

[0012] As a preferred embodiment of the above technical solution, the pressing roller is movably connected to both ends of a mounting plate, and the mounting plate is installed inside the feed hood.

[0013] As a preferred embodiment of the above technical solution, the speed-changing structure includes a moving gear and a speed-changing gear. The moving gear is disposed on the pressing roller, and the pushing roller is coaxially connected to the speed-changing gear to achieve reverse rotation. The speed-changing gear meshes with the moving gear and is connected to the fan blade.

[0014] As a preferred embodiment of the above technical solution, the magnetic oscillation structure includes:

[0015] A rectangular cover, connected to the gas collection cover;

[0016] A disc is disposed at the end of the moving gear;

[0017] Two magnetic components are symmetrically arranged on the outer side of the disk.

[0018] A cylinder is disposed within the rectangular cover;

[0019] A pendulum needle is located on the outer side of the cylinder;

[0020] The second magnetic component is located on the outside of the pendulum needle.

[0021] As a preferred embodiment of the above technical solution, the outer side of one of the magnetic components has opposite magnetic poles to the outer side of the other magnetic component, while the outer side of the other magnetic component has the same magnetic poles as the outer side of the other magnetic component, thereby driving the pendulum needle to rotate through the action of the magnetic poles.

[0022] As a preferred embodiment of the above technical solution, the rectangular cover is provided with two air vents, and the oscillating needle blocks one of the air vents of the rectangular cover when it rotates.

[0023] As a preferred embodiment of the above technical solution, the magnetic oscillation structure further includes an air intake pipe, which connects the air collection shroud and the rectangular shroud, and is used to guide the airflow generated by the fan blades into the rectangular shroud.

[0024] As a preferred embodiment of the above technical solution, the converging shroud is provided with a synchronous exhaust structure, wherein the synchronous exhaust structure is:

[0025] An elastic element is disposed within the cavity inside the converging cover;

[0026] A baffle is connected to the elastic member;

[0027] A sealing column is connected to the baffle.

[0028] The baffle is stretched by the airflow pressure, which separates the sealing column from the jet pipe.

[0029] As a preferred embodiment of the above technical solution, the elastic element is an elastic telescopic rod. When the pressure inside the cavity increases, the baffle drives the elastic element to stretch, thereby separating the sealing column from the jet pipe.

[0030] The beneficial effects of this invention are as follows:

[0031] (1) This device achieves revolutionary improvement through double roller cooperative mechanical layering. The high-speed reverse rotation of the roller generates strong resistance force, allowing only a single layer of castor leaves to pass through the gap between it and the pressing roller. The pressing roller rotates forward to comb the leaves synchronously, so that the castor leaves on the surface of the conveyor belt are evenly arranged in a single layer. This design keeps the amount of castor leaves entering the breeding tank constant per unit time. Compared with manual feeding, the utilization rate of castor leaves is improved, eliminating the chronic problem of waste from residual leaves and localized hunger of silkworms, and providing a balanced nutritional basis for the silkworms.

[0032] (2) The pressing roller drives the fan blade to generate airflow. After being gathered by the gas collection hood, the airflow path is periodically switched by the magnetic oscillating needle mechanism, so that the two rows of reverse jet pipes spray alternately. The synchronous exhaust structure ensures that all nozzles in the single-sided cavity open synchronously under the air pressure threshold. The airflow accurately covers the blank area of ​​the conveyor belt, and blows the upper castor leaves blocked by the push roller into the blind area, improving the uniformity of castor leaf coverage.

[0033] (3) The device overcomes the bottleneck of castor leaf conveying blockage through a dual-stage anti-blocking design of mechanical blockage and dynamic purging. The push roller breaks the multi-layer castor leaf stacking structure, eliminating the risk of leaf entanglement. The rotating shaft pre-disperses the feed castor leaves to avoid initial accumulation. The high-speed airflow driven by the pressing roller forms a continuous purging in the conveying channel, inhibiting leaf adhesion. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0043] Example 1

[0044] This invention provides an automated breeding device for castor silkworms, such as... Figures 1 to 7 As shown, the assembly includes: a feed hood 1, a conveyor frame 2, a cultivation tank 3, a conveyor belt 6, and a castor leaf layering replenishment assembly; the feed hood 1 guides the castor leaves in; the conveyor frame 2 is connected below the feed hood 1; the conveyor belt 6 is located inside the conveyor frame 2 and the feed hood 1; the cultivation tank 3 is located on the conveyor belt 6 of the conveyor frame 2; the castor leaf layering replenishment assembly includes: a pressing roller 8, a drive component 9, a push roller 10, a fan blade 113, a speed-changing structure, a magnetic oscillation structure, a gas collecting hood 114, a converging hood 131, a cavity 132, and a jet pipe 136; the pressing roller 8 is located above the discharge end of the conveyor belt 6; the push roller 10 is located at the front end of the pressing roller 8 (close to the feed hood 1) and rotates in the opposite direction to the pressing roller 8; the drive component 9 synchronously drives the pressing roller 8 to rotate forward and push... The moving roller 10 rotates in the opposite direction; the speed-changing structure connects the pushing roller 10 and the pressing roller 8; the fan blade 113 is located on the speed-changing structure; the air collecting hood 114 is located at one end of the fan blade 113 and is connected to the magnetic oscillation structure; the magnetic oscillation structure is located above the air collecting hood 114 and controls the airflow direction; the converging hood 131 is connected to one end of the air collecting hood 114; the cavity 132 is separated and located inside the converging hood 131; the jet pipe 136 is set corresponding to each cavity 132; the pushing roller 10 blocks the upper layer of the multi-layer castor leaves, and the single layer of castor leaves enters the cultivation tank 3 through the pressing roller 8; the pressing roller 8 drives the fan blade 113 to generate airflow through the speed-changing structure, and the magnetic oscillation structure controls the airflow to alternately enter different cavities 132 and then be ejected along the jet pipe 136, so that the multi-layer castor leaves enter the blank area at the top of the conveyor belt 6.

[0045] Traditional castor leaf feeding relies heavily on extensive conveying methods (such as simple belt conveyors and manual scattering), which cannot control the amount of castor leaves conveyed and the uniformity of distribution. The superimposed castor leaves can easily block the conveying channels, and blank areas are likely to appear during the conveying process, resulting in uneven feeding of silkworms. Waste of residual leaves and hunger of some silkworms coexist, affecting the uniformity of silkworm growth and the quality of cocooning.

[0046] To address this, a layered castor leaf replenishment component is used. The push roller 10 in the layered castor leaf replenishment component generates a resistance force on the multi-layered stacked castor leaves by rotating in the opposite direction, allowing only a single layer of castor leaves to pass through the gap between it and the pressing roller 8. This effectively avoids the "overload" problem caused by the indiscriminate accumulation of castor leaves in traditional belt conveyors. At the same time, the forward rotation of the pressing roller 8 flattens and combs the passing single layer of castor leaves, keeping the castor leaves evenly distributed on the conveyor belt 6, replacing the randomness of manual feeding. This layered control mode ensures that the amount of castor leaves entering the cultivation tank 3 in each batch is stable and controllable, avoiding both excessive waste of leaves and insufficient feeding that could lead to hunger in the silkworms, thus providing a balanced feeding basis for the silkworms.

[0047] The obstruction effect of the push roller 10 on the upper castor leaves breaks the "congestion hazard" caused by the disorderly stacking of multiple layers of castor leaves in traditional conveying, and avoids the situation where the leaves are entangled and stuck in the conveying gap;

[0048] Meanwhile, the fan blades 113 driven by the pressing roller 8 generate a stable airflow. After being gathered by the air collecting hood 114, the airflow is periodically and alternately controlled by the magnetic oscillation structure to enter different cavities 132, so that the jet pipe 136 accurately corresponds to the blank area and sprays out directional airflow. This airflow thrust can transport the upper layer of castor leaves that are blocked by the pushing roller 10 in the multi-layer castor leaves to the blank area at the top of the conveyor belt 6. Compared with the situation in traditional conveying where the blank area cannot be filled in time, this design greatly improves the coverage of castor leaves on the conveyor belt 6, ensuring that the silkworms in each area of ​​the cultivation tank 3 can get enough castor leaves, fundamentally solving the contradiction of some silkworms being hungry and waste of residual leaves.

[0049] In use, the castor leaf conveyor line (existing technology) transports castor leaves to the feed hood 1, where they fall onto the conveyor belt 6. The drive unit 9 (drive motor) is started, driving the pressing roller 8 to rotate. When the pressing roller 8 rotates, it drives the push roller 10 to rotate in the opposite direction through the speed change structure, and at the same time drives the fan blade 113 to rotate. The rotation of the fan blade 113 generates airflow, which enters the gas collection hood 114. The rotation of the pressing roller 8 also drives the magnetic oscillating structure to run, so that the gas periodically and alternately enters different cavities 132 inside the collecting hood 131, and then blows alternately to both sides (e.g., synchronously towards the drive unit 9 or away from the drive unit 9) along the corresponding jet pipe 136.

[0050] Specifically, a conveyor frame 2 is welded to the bottom of the discharge port of the feed hood 1. A cultivation tank 3 is mounted on the conveyor frame 2. Conveyor belts 6 are installed inside both the conveyor frame 2 and the feed hood 1. A detection box 4 is installed on one side of the top of the conveyor frame 2 (the above is prior art and will not be described in detail here). A rotating shaft 5 is rotatably connected inside the conveyor frame 2. The rotating shaft 5 is externally powered, and the external power drives the rotating shaft 5 to rotate, dispersing the castor leaves collected inside the feed hood 1. Mounting plates 7 are symmetrically mounted inside the feed hood 1 using screws. A pressure roller 8 is rotatably connected between the two mounting plates 7, one of which... A drive component 9 (a drive motor) is mounted on one end of the mounting plate 7 via screws. The output shaft of the drive component 9 is connected to the pressing roller 8 via a key. A speed-changing structure is mounted on the pressing roller 8 at one end of the other mounting plate 7. A fan blade 113 is mounted on one end of the speed-changing structure, and a push roller 10 penetrating the mounting plate 7 is mounted on the other end. The push roller 10 is rotatably connected between the two mounting plates 7. A magnetic oscillation structure is mounted on one end of the speed-changing structure. A gas collection hood 114 is mounted on one end of the fan blade 113, and one end of the gas collection hood 114 is fixed to the mounting plate 7 via a column (e.g., ...). Figure 4 As shown), a converging hood 131 is installed at one end of the gas collecting hood 114. Two cavities 132 are opened inside the converging hood 131. An air jet pipe 136 is installed at the bottom of the converging hood 131. The air jet pipe 136 is arranged in two rows, corresponding to the two cavities 132 respectively, and the air jet directions of the two rows of air jet pipes 136 are opposite.

[0051] like Figure 3 and Figure 4 As shown, in order to make the fan blade 113 rotate rapidly and generate airflow, the speed change structure includes a drive gear 111 and a speed change gear 112. The drive gear 111 is located on the pressing roller 8, and the push roller 10 is coaxially connected to the speed change gear 112 to achieve reverse rotation. The speed change gear 112 meshes with the drive gear 111 and is connected to the fan blade 113.

[0052] In use, the rotating pressing roller 8 drives the rotating gear 111 to rotate, and the rotating gear 111 drives the speed-changing gear 112 to rotate rapidly. The speed of the speed-changing gear 112 is higher than that of the rotating gear 111, thereby driving the fan blade 113 to rotate at high speed and generate airflow, while simultaneously driving the push roller 10 to rotate in the opposite direction. Figure 3 (As shown).

[0053] Specifically, one end of the pressing roller 8 is located outside a mounting plate 7 and is connected to a moving gear 111 by a key. A speed-changing gear 112 is meshed with the outside of the moving gear 111. The size of the moving gear 111 is larger than that of the speed-changing gear 112. One end of the speed-changing gear 112 is fixedly connected to the fan blade 113, and the other end of the speed-changing gear 112 is connected to the push roller 10 by a key.

[0054] like Figures 3 to 5As shown, to prevent gas from continuously ejecting in one direction, the gas flow direction needs to be changed so that the gas circulates and ejects in a cross pattern, preventing castor leaves from converging in one direction and causing them to accumulate. Therefore, the magnetic oscillation structure includes: an air inlet pipe 121, a rectangular cover 122, a disc 123, a magnetic component 124, a cylinder 125, a oscillating needle 126, and a magnetic component 127. The rectangular cover 122 is connected to the gas collecting cover 114. The air inlet pipe 121 connects the gas collecting cover 114 and the rectangular cover 122, and is used to guide the airflow generated by the fan blade 113 into the rectangular cover 122. The disc 123 is located at the end of the moving gear 111. Magnetic components 124 are symmetrically arranged outside the disc 123 (e.g., symmetrically arranged at 180 degrees), and there are two of them. The cylinder 125 is located inside the rectangular cover 122. The oscillating needle 126 is located outside the cylinder 125. Magnetic component 127 is located outside the oscillating needle 126.

[0055] In use, the airflow inside the gas collection hood 114 enters the rectangular hood 122 through the air inlet pipe 121. At this time, when the moving gear 111 rotates, it drives the magnetic component 124 to rotate through the disk 123. When the magnetic component 124 rotates, its magnetic field interacts (attracts or repels) with the magnetic component 127 on the pendulum needle 126, driving the pendulum needle 126 to swing periodically around the cylinder 125. When the pendulum needle 126 swings, it alternately blocks one of the two air outlets of the rectangular hood 122, thereby realizing the alternating entry of airflow into different channels and forming a periodic switching of gas flow direction.

[0056] Specifically, the outlet end of the gas collecting hood 114 is connected to an air inlet pipe 121, and the outlet end of the air inlet pipe 121 is connected to a rectangular cover 122. A disc 123 is fixedly installed at the end of the moving gear 111 furthest from the driving component 9. Two magnetic components 124 are snapped onto the outside of the disc 123. The magnetic pole directions of the two magnetic components 124 need to be specifically set (e.g., NS and SN). A cylinder 125 is embedded inside the rectangular cover 122, and a swivel pin 126 is sleeved on the outside of the cylinder 125. The rectangular cover 122 has two air outlets. A pipe is connected to the outside of the air outlet 122, which is connected to the inside of the cavity 132. When the pendulum needle 126 rotates, it blocks one of the air outlets of the rectangular cover 122. A magnetic component 127 is snapped onto the outside of the pendulum needle 126. The magnetic poles of one magnetic component 124 are opposite to those of the magnetic component 127 (generating an attractive force), while the magnetic poles of the other magnetic component 124 are the same as those of the magnetic component 127 (generating a repulsive force). The change in the position of the magnetic poles caused by the rotation of the disk 123 drives the pendulum needle 126 to swing back and forth.

[0057] like Figure 3 and Figure 6As shown, since multiple jet pipes 136 are provided inside the converging hood 131, in order to ensure that the multiple jet pipes 136 exhaust gas synchronously and to prevent the exhaust gas from a single jet pipe 136 from causing some castor leaves on the conveyor belt 6 to be unable to move, a synchronous exhaust structure is provided inside the converging hood 131. The synchronous exhaust structure includes a sealing column 133, a baffle 135, and an elastic element 134. The elastic element 134 is located in the cavity 132 inside the converging hood 131. The baffle 135 is connected to the elastic element 134. The sealing column 133 is connected to the baffle 135.

[0058] In use, when the airflow enters a cavity 132 of the converging shroud 131, the air pressure inside the cavity 132 gradually increases. When the air pressure increases to a level sufficient to overcome the pre-tightening force of the elastic element 134, it pushes the baffle 135 and the sealing column 133 to move upward, stretching the elastic element 134. After the sealing column 133 moves upward, it disengages from the inlet of the jet pipe 136, and the gas inside the cavity 132 is simultaneously ejected from all the jet pipes 136 corresponding to that cavity.

[0059] When the airflow pressure decreases, the elastic element 134 contracts, causing the baffle 135 and the sealing column 133 to move down and reset, resealing the jet pipe 136.

[0060] Specifically, an elastic element 134 is installed inside the cavity 132 of the converging shroud 131. When the pressure inside the cavity 132 increases, the baffle 135 drives the elastic element 134 to stretch, thereby separating the sealing column 133 from the jet pipe 136. The elastic element 134 is an elastic telescopic rod and there are eight of them. Four elastic elements 134 form a group, and a group of elastic elements 134 is located at the four corners of the inner wall of the cavity 132. The top of the four elastic elements 134 is connected to the same baffle 135. The bottom of the baffle 135 is fixedly installed inside the jet pipe 136. The baffle 135 is driven by the airflow pressure to stretch the elastic element 134, thereby separating the sealing column 133 from the jet pipe 136.

[0061] Working principle: In actual use, the external castor leaf conveyor line (existing technology) feeds the castor leaves into the feed hood 1. The castor leaves fall onto the conveyor belt 6 through the feed hood 1. The conveyor belt 6 transports the castor leaves and, during the falling process, the castor leaves are initially dispersed by the rotating shaft 5 inside the conveyor frame 2 to prevent initial accumulation.

[0062] At this time, the drive unit 9 (drive motor) starts, driving the pressing roller 8 to rotate in the forward direction. The pressing roller 8 synchronously drives the push roller 10 to rotate in the reverse direction at high speed through the speed change structure (moving gear 111 and speed change gear 112). When the push roller 10 rotates in the reverse direction at high speed, it blocks the upper stacked castor leaves and only allows a single layer of castor leaves to flow through the gap between it and the pressing roller 8. Since the push roller 10 rotates at high speed, it drives the fan blade 113 to rotate at high speed. When the fan blade 113 rotates at high speed, it generates airflow and guides it into the air collection hood 114.

[0063] The single-layer castor leaves passing through the gap are flattened and combed by the pressing roller 8 rotating in the forward direction, and evenly distributed on the surface of the conveyor belt 6. The conveyor belt 6 continuously transports the flattened single-layer castor leaves to the area of ​​the rearing tank 3 for silkworms to feed, thus realizing quantitative feeding.

[0064] The rotation of the pressing roller 8 drives the disk 123 and the magnetic component 124 to rotate. The magnetic component 124, which is symmetrically arranged on the disk 123, alternately approaches the magnetic component 127 of the pendulum needle 126. The magnetic pole action (attraction / repulsion) of the magnetic component 124 and the magnetic component 127 drives the pendulum needle 126 to swing periodically around the cylinder 125. The pendulum needle 126 swings and alternately blocks the two air outlets of the rectangular cover 122. At this time, the airflow is periodically switched along the pipe and enters one of the cavities 132 inside the converging cover 131.

[0065] After switching, the airflow enters a cavity 132 of the converging hood 131, causing the air pressure in the cavity 132 to rise. When the air pressure overcomes the pre-tightening force of the elastic element 134, it pushes the baffle 135 to move upward, stretching the elastic element 134. The baffle 135 drives the sealing column 133 to disengage from the inlet of the jet pipe 136. All the jet pipes 136 corresponding to the cavity 132 open synchronously, so that the gas blows the castor leaves at the top of the conveyor belt 6. The two rows of jet pipes 136 alternately spray directional airflow according to the airflow switching direction (e.g., synchronously towards the drive element 9 or away from the drive element 9). The directional airflow accurately blows the upper castor leaves blocked by the push roller 10 to the blank area at the top of the conveyor belt 6. The airflow injection and castor leaf conveying are carried out synchronously, eliminating the coverage blind spot in real time and ensuring that the castor leaves are evenly distributed throughout the cultivation tank 3.

[0066] At the same time, the conveyor belt 6 on the conveyor frame 2 drives the cultivation tank 3 to move, so that the castor leaves enter different parts of the cultivation tank 3, thus achieving the purpose of replenishing the cultivation tank 3 with castor leaves.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
