Description

Technical Field

[0001] This invention relates to the field of sericulture machinery and equipment technology, specifically to an automated silkworm rearing equipment and method. Background Technology

[0002] Silkworm farming is a traditional breeding technique. Generally, silkworms are raised on silkworm trays, which are open-mouthed containers similar to winnowing baskets. They have advantages such as being lightweight and dehydrating quickly.

[0003] Traditional silkworm farming involves distributing large numbers of silkworms in silkworm trays, which are then placed on shelves and stacked from bottom to top. In artificial silkworm farming, the silkworms in the trays need to be fed mulberry leaves every few hours, and the trays need to be cleaned every one or two days. This requires manual labor to remove the trays from the shelves, feed them, clean them, and then place them back on the shelves. This process involves manually moving the trays, feeding them, disinfecting them, and then stacking them up – a very labor-intensive, time-consuming, slow, and inefficient process. Summary of the Invention

[0004] This invention provides an automated silkworm rearing equipment and method to solve the technical problem that the manual handling of silkworm trays, feeding of mulberry leaves, disinfection, and then stacking of them during the transportation process is extremely labor-intensive.

[0005] To achieve the above objectives, the present invention provides an automated silkworm rearing equipment, comprising: a conveying device for conveying silkworm trays, wherein silkworm tray unloading and stacking devices are provided at both ends of the conveying device;

[0006] A disinfection device and a unloading device are provided in the direction of conveying from unloading the silkworm trays to stacking the silkworm trays, and the disinfection device and the unloading device are located above the conveying device.

[0007] By adopting the above technical solution, the silkworm trays are placed on the silkworm tray unloading device, and the silkworm trays are unloaded one by one and transported on the conveying device. When the silkworm trays reach the bottom of the disinfection device, the disinfection device will sprinkle quicklime. Then they reach the bottom of the unloading device, and the unloading device will sprinkle mulberry leaves on the surface of the silkworm trays through the unloading port. Finally, the silkworm trays reach the silkworm tray stacking device and are stacked.

[0008] Among them, the silkworm tray set consists of multiple layers of silkworm trays stacked together.

[0009] Furthermore, the silkworm tray unloading and stacking device includes: a lifting device for lifting the silkworm tray on the conveying device, and a supporting device for supporting the silkworm tray being lifted.

[0010] By adopting the above technical solution, the conveying device transports the silkworm trays to the designated position, and the lifting device and supporting device stack or unstack the silkworm trays, thereby realizing the automatic stacking of several silkworm trays and the removal of several silkworm trays in the stacked state one by one, reducing the intensity of manual labor and saving time and labor costs.

[0011] Furthermore, the device also includes a silkworm tray, which comprises a feeding tray and a sand removal tray; the bottom of the feeding tray has a mesh structure, and the feeding tray is located above the sand removal tray;

[0012] The sand removal tray includes: a movable plate disposed at the bottom of the sand removal tray; one end of the movable plate is hinged to the sand removal tray, and the other end is provided with a buckle structure for stabilizing the movable plate.

[0013] By adopting the above technical solution, silkworms are fed in a feeding tray, and silkworm excrement falls into a sand removal tray through a mesh structure. During the feeding process, when the silkworm tray reaches the designated position, the latch will open, thereby removing sand from the silkworm tray.

[0014] Furthermore, the buckle structure includes: a fixing block on the bottom surface of the sand removal tray, a rotating shaft rotating along the axis on the surface of the fixing block, and a V-shaped support plate at the end of the rotating shaft; a torsion spring between the fixing block and the V-shaped support plate, one end of the torsion spring being fixedly connected to the fixing block and the other end being fixedly connected to the V-shaped support plate;

[0015] A limiting block is provided on the conveying device, and the limiting block is located on the side of the V-shaped support plate.

[0016] By adopting the above technical solution, the left side of the V-shaped support plate is used to support the movable plate, and the right side is used to contact the limiting block. As the silkworm disc is continuously conveyed forward on the conveying device, the torsion spring is in normal condition. When the surface of the V-shaped support plate contacts the surface of the limiting block, the V-shaped support plate will rotate along the axis of the rotating shaft, so that the V-shaped support plate will no longer support the movable plate. The silkworm disc at the other end rotates downward with the hinge point as the rotation point. This causes the silkworm excrement on the sand removal disc to fall out through the inclined plane. When the silkworm disc has completely passed the limiting block, the torsion spring, which is in a compressed state, will return to its initial state, thereby causing the rotating shaft to drive the V-shaped support plate to return to its initial state.

[0017] Furthermore, the disinfection device includes: a storage box, the interior of which is provided with a cavity for storing disinfection materials, and a second electronic control switch is provided at the bottom of the cavity.

[0018] By adopting the above technical solution, when the silkworm tray located on the conveying device is conveyed to the bottom of the storage box, the second electric control switch will be automatically turned on, and the disinfectant material stored inside the storage box will be sprinkled onto the silkworm tray.

[0019] Furthermore, the unloading device includes: a frame mounted on the conveying device, the surface of the frame being provided with a first slide rail assembly, the surface of the first slide rail assembly being provided with a mixing section and a power section for driving the mixing section to rotate;

[0020] A feeding box is provided below the first slide rail assembly, and a first electric control switch is provided at the bottom of the feeding box.

[0021] Furthermore, the mixing section is a tank, and the tank has a mixing cavity inside. The tank has mixing blades with a spiral structure arranged from top to bottom along the axial direction.

[0022] By adopting the above technical solution, the inventors discovered that traditional methods of stirring mulberry leaves damage the leaf surface, causing the sap to leak out. When mulberry leaves are sprinkled on quicklime, the sap mixes with the quicklime, creating a highly alkaline environment for silkworms. This is detrimental to silkworm growth and may even lead to their death. Based on this, the present invention proposes an automated silkworm rearing device, comprising: a mixing unit, which is a tank with a mixing cavity inside. The tank has spiral mixing blades arranged from top to bottom along its axial direction. Mulberry leaves are placed inside the tank, and the tank rotates around its own axis, centrifugally mixing the mulberry leaves with auxiliary materials. This method allows the mulberry leaves to mix with the auxiliary materials without damaging the leaves themselves.

[0023] In addition, because the feeding tray has a mesh structure, when the disinfection device sprinkles slaked lime, some of the slaked lime will fall through the mesh structure into the sand removal tray, making it difficult to achieve a good cleaning effect. However, the leaves mixed in the mixing section contain slaked lime. When the mulberry leaves are sprinkled, lime remains on the surface of the mulberry leaves and between the mulberry leaves. This lime will not fall through the mesh structure into the sand removal tray, which helps to improve the disinfection effect in the silkworm tray.

[0024] Furthermore, the mixing section is provided with a limiting rod for stabilizing the mixing section.

[0025] By adopting the above technical solution, the limiting rod can be used to stabilize the mixing unit when the power unit drives the mixing unit.

[0026] Furthermore, the device also includes several sensors for monitoring the position of the silkworm trays, all of which are connected to a controller. The controller is used to control the operation of the conveying device, the silkworm tray unloading and stacking device, the disinfection device, and the unloading device.

[0027] Furthermore, it includes the following steps:

[0028] S1: Place the silkworm trays on the silkworm tray unloading and stacking device at one end of the conveying device, and unload them one by one by the lifting device and the support device group.

[0029] S2: The unloaded silkworm trays are conveyed on the conveyor device;

[0030] S3: When the silkworm tray passes through the disinfection device, the first electronic control switch is turned on, and the quicklime placed inside the cavity is sprinkled inside the silkworm tray.

[0031] S4: When the silkworm tray passes the unloading device, the second electric control switch is turned on to feed mulberry leaves into the silkworm tray;

[0032] S5: When the silkworm tray reaches the designated position, the buckle structure at the bottom of the silkworm tray opens, allowing the silkworm excrement in the sand removal tray at the bottom of the silkworm tray to fall out.

[0033] S6: When the silkworm trays reach the silkworm tray unloading and stacking device at the other end of the conveying device, the lifting device will fasten the buckle structure, thereby realizing the stacking of the silkworm trays.

[0034] The automated silkworm rearing equipment and method provided by this invention have at least the following technical effects:

[0035] 1. This application includes: a conveying device, a silkworm tray unloading and stacking device, a disinfection device, and a unloading device. This structure enables the silkworm tray group to be unloaded one by one, and each silkworm tray to be disinfected and fed, and then stacked one by one, reducing labor costs.

[0036] 2. The silkworm tray unloading and stacking device includes a silkworm tray unloading device and a silkworm tray stacking device. The unloading device and the stacking device have the same mechanical structure but perform different operations. The structure is simple and has good practical effect.

[0037] 3. The silkworm tray in this application has a double-layer structure, with one layer for raising silkworms and the other layer for storing silkworm excrement, thus ensuring the cleanliness of the tray surface.

[0038] 4. The bottom of the silkworm tray is also equipped with a buckle structure for stabilizing the movable plate. This structure can process the silkworm excrement inside the sand removal tray, improve the cleanliness of the silkworm tray, and at the same time reduce the labor cost of manual sand removal.

[0039] 5. This application also includes: a mixing section, which removes the quicklime in the silkworm tray during the sand removal process, thus failing to achieve the effect of disinfecting the silkworm tray. The mixing section is used to mix mulberry leaves and quicklime, so that the mulberry leaves directly contain lime, thereby achieving the effect of disinfecting the silkworm tray.

However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0051] Example 1

[0052] An automated silkworm rearing device, please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 It includes: a conveying device 1 for conveying silkworm trays, wherein silkworm tray unloading and stacking devices 2 are provided at both ends of the conveying device 1;

[0053] A disinfection device 3 and a unloading device 4 are provided in the direction of conveying from unloading the silkworm trays to stacking the silkworm trays, and the disinfection device 3 and the unloading device 4 are located above the conveying device 1.

[0054] Among them, the conveying device 1, the silkworm tray unloading and stacking device 2, the disinfection device 3 and the unloading device 4 are all installed on the first support. The conveying device 1 is a belt conveyor line, and the first belt conveyor line and the second belt conveyor line are symmetrically distributed. The silkworm tray unloading and stacking device 2 includes: a silkworm tray unloading device and a silkworm tray stacking device. The silkworm tray unloading device is located at one end of the belt conveyor line, and the silkworm tray stacking device is located at the other end of the belt conveyor line.

[0055] Example 2

[0056] Based on Example 1, please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The silkworm tray unloading and stacking device 2 includes: a lifting device 201 for lifting the silkworm tray on the conveying device 1, and a supporting device 202 for supporting the silkworm tray being lifted.

[0057] The support device 202 includes a first support device and a second support device, which are arranged in a mirror image on both sides of the conveying device 1; a lifting device 201 is disposed between the first support device and the second support device, and the lifting device 201 is located inside the conveying device 1; the first support device, the second support device, and the lifting device 201 are located at the same end of the conveying device. Since the first support device and the second support device have the same structure, only the specific structure of the first support device will be discussed in this embodiment.

[0058] The first support device includes a horizontal plate 203 and a vertical plate 204, which form an "L" shape. A support part 205 is provided above the horizontal plate, and a second slide rail group 206 is fixedly arranged between the horizontal plate and the support part 205. The support device 202 includes a first drive part 207, which is arranged parallel to the top surface of the support part 205. A baffle 208 is fixedly provided at one end of the first drive part 207, and the baffle 208 is perpendicular to the top surface of the support part 205. The other end is fixedly connected to the vertical plate 204. In addition, the first drive part 207 uses an electric push rod to drive the support part 205 to perform linear reciprocating motion.

[0059] The lifting device 201 includes a lifting plate 209 and a base plate 210. The base plate 210 is mounted on a first bracket. A second drive unit 211 is provided between the lifting plate 209 and the base plate 210 for driving the lifting plate 209 to perform linear reciprocating motion. The second drive unit 211 is an electric push rod.

[0060] The stacking process of silkworm trays includes: First, placing the silkworm tray 5 on the conveying device 1, that is, the silkworm tray 5 gradually approaches the lifting device 201 from a distance. When the silkworm tray 5 reaches directly above the lifting device 201, the lifting device 201 raises the vertical height of the first silkworm tray from its bottom until the height is higher than the working plane of the support device 3. Then, the support device 202 lifts the first silkworm tray from its side bottom to support it. At the same time, the lifting device 201 detaches from the first silkworm tray and returns to its initial state.

[0061] The second silkworm tray is placed on the conveying device 1, which transports it to a designated position. At this point, the second silkworm tray is directly below the first silkworm tray. The lifting device 201 raises the second silkworm tray vertically from its bottom until the top surface of the second silkworm tray contacts the bottom surface of the first silkworm tray. The lifting device 201 then stops moving. If the lifting device continues to move upward at this point, the support device 202 supporting the first silkworm tray will be squeezed by the rising lifting device 201, thus damaging the first silkworm tray. The support device 202 detaches from the first silkworm tray, and the lifting device 201 continues to move upward until this height is higher than the working plane of the support device 202. At this point, the support device 202 will lift the second silkworm tray from its side, thus supporting both the first and second silkworm trays. Simultaneously, the lifting device 201 will detach from the second silkworm tray and return to its initial state.

[0062] Repeat the above process to stack the silkworm trays. This silkworm tray palletizing machine can not only stack silkworm trays, but also unpack them from the stacks, as follows:

[0063] Several stacked silkworm trays are placed on the conveying device 1. When the silkworm trays reach directly above the lifting device 2, the lifting device 201 raises the vertical height of the silkworm trays. The silkworm trays are sequentially defined from bottom to top as silkworm tray three, silkworm tray four, and silkworm tray five, until the height of silkworm tray four is equal to the working plane of the supporting device 202. The supporting device 202 lifts silkworm tray four from the bottom side of its side. At this time, the lifting device 201 gradually returns to its initial state. During this process, since silkworm tray three remains on the conveying device 1, it can continue to be transported downstream through the conveying device 1. After silkworm tray three is transported away, the lifting device 201 continues to move upward until it contacts silkworm tray four. At this time, the supporting device 202 disengages from the fourth silkworm tray. The lifting device 201 moves downward until it reaches a position where the supporting device 202 can support silkworm tray five from the bottom side of its side. The supporting device 202 supports silkworm tray five, while silkworm tray four continues to move downward until its bottom surface contacts the surface of the conveying device 1 for transport.

[0064] By repeating the above process, the stacked silkworm trays can be unstacked one by one, so that the stacked silkworm trays 5 can be laid out one by one on the conveying device.

[0065] Example 3

[0066] Based on Example 2, please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The device further includes a silkworm tray 5, which includes a feeding tray 501 and a sand removal tray 502; the bottom of the feeding tray 501 has a mesh structure, and the feeding tray 501 is located above the sand removal tray 502.

[0067] The sand removal tray 502 includes: a movable plate 503 503 disposed at the bottom of the sand removal tray 502; one end of the movable plate 503 is hinged to the sand removal tray 502, and the other end is provided with a buckle structure 6 for stabilizing the movable plate 503.

[0068] In a more preferred embodiment, the buckle structure 6 includes: a fixing block 601 on the bottom surface of the sand removal disc 503, a rotating shaft 602 rotating along an axis on the surface of the fixing block 601, and a V-shaped support plate 603 at the end of the rotating shaft 602; a torsion spring between the fixing block 601 and the V-shaped support plate 603, one end of the torsion spring being fixedly connected to the fixing block 601 and the other end being fixedly connected to the V-shaped support plate 603;

[0069] A limiting block 7 is provided on the conveying device, and the limiting block 7 is located on the side of the V-shaped support plate 603.

[0070] The feeding tray 501 is a rectangular open container with a mesh bottom, and a fence is fixedly connected around its perimeter. The sand removal tray 502 is also a rectangular open container, and the feeding tray 501 and sand removal tray 502 are fixedly connected. Silkworm excrement falls onto the movable plate 503 through the upper mesh structure, thus storing the excrement. When the V-shaped support plate 603 encounters the limiting block, it becomes attached. Figure 7 The position of the middle snap-fit ​​structure A encounters the attached Figure 4 At the position of the middle limit block B, as the conveying device continuously transports the silkworm tray forward, the V-shaped support plate 603 will rotate along the axis of the rotating shaft 602, causing the V-shaped support plate 603 to no longer support the movable plate 503. At the other end, due to the hinge, the silkworm tray rotates downward with the hinge as the rotation point under its own gravity. At this time, the movable plate 503 is in an inclined state, causing the silkworm tray to continuously fall out of the sand removal tray, thereby achieving the effect of removing sand from the silkworm tray 5. As the conveying device continues to transport the silkworm trays, the snap-fit ​​structure will completely pass through the limit block, causing the torsion spring on the rotating shaft 602 to automatically return to its initial state. When the silkworm trays reach the silkworm tray stacking device, the lifting device lifts the silkworm trays from the bottom. At this time, under the action of the lifting device, the supporting part on the left side of the V-shaped support plate 603, which is made of plastic elastic material, moves along the inclined surface of the V-shaped support plate 603. The moving plate 503 then presses against the supporting part of the V-shaped support plate 603 until the moving plate 503 reaches the top of the silkworm tray 5, thus achieving the snap-fit ​​between the supporting part of the V-shaped support plate 603 and the moving plate 503, thereby supporting the moving plate 503.

[0071] In addition, a limiting rope is provided on the movable plate 503 so that the lowest point of the movable plate 503 is higher than the highest point of the lifting device in its normal state.
