Abstract
Description
Technical Field
[0001] This invention relates to the field of cocoon harvesting, and more specifically to a grid-stacking and conveying cocoon harvesting device. Background Technology
[0002] A cocoon-collecting device is a specialized tool used in the sericulture industry to harvest cocoons from mature silkworms after they have spun them in a cocooning frame. The square-grid cocooning frame is currently the highest quality cocooning frame used in the sericulture industry and is also the most widely used frame by silkworm farmers.
[0003] The commonly used square cluster cocoon harvesting device on the market includes a frame, a drive unit, and a cocoon picking mechanism. The frame is equipped with a cluster-laying platform, and the cluster-laying platform has a cocoon dropping opening located below the cocoon picking mechanism. The cluster-laying platform is equipped with a cluster clamping device. The cocoon picking mechanism includes a transmission mechanism and several cocoon-topping strips. After the cocoon picking mechanism pushes the cocoons out of the square cluster, they fall through the cocoon dropping opening. The cocoon dropping opening can be connected to a cocoon collecting device to collect the fallen cocoons.
[0004] However, this device requires manual placement of the square clusters on the placement platform before sequential conveying, resulting in low efficiency. Existing square cluster stacking devices stack square clusters on the placement platform and then convey them sequentially onto a conveyor belt. However, during the descent of the square clusters, the cocoons on the clusters are prone to detaching, affecting cocoon recovery. Summary of the Invention
[0005] One objective of this invention is to provide a cocoon harvesting device that uses a grid cluster stacking and conveying mechanism to vertically place and transport several grid clusters, and uses an adjusting mechanism to rotate the grid clusters 90 degrees to position them on a first conveying rod for transport, thereby avoiding the problem of cocoons separating from the grid clusters caused by vertical stacking.
[0006] This objective is achieved using the following technical solution:
[0007] A cocoon harvesting device for stacking and conveying square clusters includes a cocoon picking mechanism, a conveying mechanism, and several square clusters. The cocoon picking mechanism includes a cluster placement platform with a cocoon dropping opening. The conveying mechanism is connected to the cluster placement platform and is used to transport several clusters to the cluster placement platform to avoid manual placement.
[0008] The conveying mechanism of this device includes two first conveying rods, two second conveying rods above the first conveying rods, and an adjusting rod below the first conveying rods. The adjusting rod is equipped with an adjusting mechanism. Several square clusters are vertically arranged on the first and second conveying rods. The first and second conveying rods are used to convey the square clusters. Under the action of the first and second conveying rods, the square clusters move towards the cluster placement platform. When the square clusters move to the end of the second conveying rods, the adjusting mechanism acts on the square clusters, causing the square clusters to rotate 90 degrees, separate from the second conveying rods, and lie flat on the first conveying rods. The flat square clusters are then conveyed through the first conveying rods.
[0009] In the process of forming cocoons on the upper grid of the large silkworm, several grids are placed vertically. Therefore, in order to simplify the operation, the first and second conveyor rods of this device place the grids vertically. After the cocoons on the upper grid of the large silkworm are formed, they can be directly conveyed to the first and second conveyor rods, making the operation more convenient.
[0010] When the grid cluster is at the end of the second conveyor rod, the adjusting mechanism rotates the cluster 90 degrees from a vertical to a horizontal position. Compared to existing conveyor mechanisms where grid clusters are stacked from top to bottom, this device prevents the upper grid clusters from moving downwards due to gravity after the bottom cluster is pushed out. During this downward movement, the grid clusters are subjected to forces that can easily cause separation between the cocoons and the clusters, thus affecting the final cocoon harvesting efficiency and quality. In this device, adjacent grid clusters do not interact or affect each other during transport. Furthermore, compared to existing structures, this device can transport a greater number of grid clusters simultaneously and is easier to operate.
[0011] Furthermore, the adjustment mechanism in this device can have various structures, such as a rotating plate connected to a rotating shaft, which drives the rotating plate to rotate 90 degrees, thereby driving the grid cluster to rotate. It can also be a telescopic rotating structure, as long as it can achieve the goal of rotating the grid cluster by 90 degrees.
[0012] However, to further protect the cocoons on the grid cluster during rotation, the inventors have preferred an adjustment mechanism. This adjustment mechanism includes a first slider and a second slider located on an adjustment rod, and a first and second action plate forming an L-shape. When the adjustment mechanism acts on the grid cluster, the first and second action plates contact the side and bottom of the grid cluster, respectively. The first and second action plates protect the grid cluster, preventing it from being subjected to excessive force. Furthermore, the contact between the first action plate and the side of the grid cluster prevents the cocoons from falling off during rotation. A connecting plate is connected to the first action plate, hinged to one end of the first rotating rod. The other end of the first rotating rod is hinged to the first slider, and the connecting plate is hinged to the second slider. The second slider can slide on the adjustment rod, causing the first and second action plates to rotate 90 degrees, thereby rotating the grid cluster 90 degrees.
[0013] In use, the first slider remains stationary, while the second slider moves away from the first slider on the adjusting rod. During the sliding process of the second slider, the first rotating rod and connecting plate rotate, causing the first and second acting plates to rotate 90 degrees. This structure has a slow rotation speed, and because the first and second acting plates act simultaneously on the grid cluster, it is easier to adjust.
[0014] Furthermore, preferably, after the first and second action plates are rotated 90 degrees, the first action plate is positioned below the first conveyor rod. This allows the grid clusters to be directly conveyed on the first conveyor rod without requiring additional operations, making it easier to use.
[0015] Furthermore, the grid clusters are equipped with upper and lower connecting rods at their top and bottom ends, respectively. When several grid clusters are vertically positioned on the first and second conveyor rods, the upper connecting rod is located at the lower end of the second conveyor rod, which supports the grid clusters, thus ensuring greater stability when placed vertically. The lower connecting rod is located at the upper end of the first conveyor rod, which supports the grid clusters, further enhancing the stability of the connection. During the conveying process, the first and second conveyor rods can move the grid clusters on them via other moving mechanisms, or via conveyor belts or conveyor components mounted on the first and second conveyor rods.
[0016] Since the upper connecting rod is located at the lower end of the second conveying rod, when the first and second action plates of this device are not rotated, the first action plate is located at the end of the second conveying rod. Thus, when the first and second action plates rotate, the upper connecting rod can rotate out from the end of the second conveying rod, separating the upper connecting rod from the second conveying rod, and directly rotating onto the first conveying rod.
[0017] Preferably, the width of the first and second action plates is smaller than the width of the two second conveying rods. When the first and second action plates rotate, they act between the two second conveying rods, which can better separate the grid cluster from the second conveying rods and can better act on the grid cluster.
[0018] Furthermore, the cocoon harvesting device includes a detection mechanism located between the cocoon picking mechanism and the conveying mechanism. The detection mechanism includes a conveyor frame for transporting the cocoon clusters. A connecting cover is installed on the conveyor frame, and within the connecting cover, along the conveying direction of the conveyor frame, are sequentially arranged detection components for detecting silkworm cocoons and screening components for screening silkworm cocoons. The conveying mechanism is equipped with a first cocoon drop outlet for collecting silkworm cocoons. The conveyor frame, the cocoon-collecting mechanism's cluster-laying platform, and two first conveyor rods are located on the same horizontal plane. The cocoon clusters can be directly transported to the conveyor frame via the first conveyor rods. After being detected on the conveyor frame, they are then transported to the cluster-laying platform via the conveyor frame.
[0019] The detection components include a camera. When the square cluster passes through the conveyor, it is first photographed by the camera. The images are compared to identify the locations of cocoons that fail the inspection. After the square cluster is conveyed to the screen, the screen removes the cocoons that fail the inspection. The cocoons that fail the inspection fall into the first cocoon drop opening. The cocoons that pass the inspection are moved to the cluster release platform by the square cluster.
[0020] Preferably, the screening component includes an adjustable grid plate with the same structure as the grid cluster. Each square of the adjustable grid plate corresponds one-to-one with the grid cluster, and each square of the adjustable grid plate is equipped with a telescopic rod. When the grid cluster moves below the screening component, that is, directly below the adjustable grid plate, the telescopic rod corresponding to the cocoon that failed the test is extended, thus removing the cocoon that failed the test.
[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0022] This invention discloses a square cluster stacking and conveying cocoon harvesting device. This device arranges several vertically placed square clusters horizontally in sequence through an adjustment mechanism, which can effectively prevent cocoons from falling out of the square clusters during transportation, improve the cocoon harvesting efficiency, and facilitate long-term use.
[0023] Meanwhile, this device uses a detection mechanism to detect the silkworm cocoons in the grid clusters and uses a screening device to remove the silkworm cocoons that fail the test, thus avoiding the mixing of untested silkworm cocoons into the clustering platform and improving the efficiency and quality of cocoon harvesting.

Therefore, they should not be construed as limiting the scope of protection of this invention.
[0039] Example 1
[0040] like Figure 1 As shown, the cocoon harvesting device includes a cocoon picking mechanism, a detection mechanism, a conveying mechanism, and several square clusters 1. The detection mechanism is located between the cocoon picking mechanism and the conveying mechanism. The detection mechanism is used to detect the quality of the silkworm cocoons and remove those that fail the screening. The cocoon picking mechanism is used to push the silkworm cocoons out of the square clusters and drop them through the cocoon dropping opening. The cocoon dropping opening can be connected to a cocoon collecting device to collect the dropped silkworm cocoons.
[0041] The conveying mechanism includes two first conveyor rods 4, a conveyor frame 15, and a clustering platform for the cocoon-picking mechanism. The two first conveyor rods 4 are located on the same horizontal plane. The two first conveyor rods 4 convey the horizontally placed square clusters to the conveyor frame, and the conveyor frame conveys the square clusters to the clustering platform. The first conveyor rods, the conveyor frame, and the clustering platform can be conveyed by a conveyor belt, or by a telescopic structure that moves the square clusters on it, or by other moving mechanisms. The inventor does not make specific limitations here, as long as the purpose of conveying can be achieved.
[0042] Based on this, such as Figure 2 As shown, two second conveyor rods 5 are arranged above the first conveyor rod 4, and an adjusting rod 6 is arranged below the first conveyor rod 4. An adjusting mechanism is provided on the adjusting rod 6. Several square clusters 1 are vertically arranged on the first conveyor rod 4 and the second conveyor rods 5. The first conveyor rod 4 and the second conveyor rod 5 are used to convey the square clusters 1. The adjusting mechanism can act on the square clusters 1 to rotate the square clusters 1 by 90 degrees and place them flat on the first conveyor rod 4.
[0043] In some embodiments, the adjustment mechanism is as follows: Figure 3 As shown, the adjustment mechanism includes a first slider 7 and a second slider 8 located on the adjustment rod 6, and a first actuating plate 11 and a second actuating plate 12 forming an L-shape, as shown in the figure. Figure 4As shown, when the adjusting mechanism acts on the grid cluster 1, the first acting plate 11 and the second acting plate 12 contact the side and lower end of the grid cluster 1, respectively. A connecting plate 10 is connected to the first acting plate 11. The connecting plate 10 is hinged to one end of the first rotating rod 9, and the other end of the first rotating rod 9 is hinged to the first slider 7. The connecting plate 10 is hinged to the second slider 8. The second slider 8 can slide on the adjusting rod 6, causing the first acting plate 11 and the second acting plate 12 to rotate 90 degrees, and driving the grid cluster 1 to rotate 90 degrees.
[0044] In use, when a cluster of squares moves to the first action plate 11 and the second action plate 12, as follows: Figure 3 As shown, the first action plate 11 is located at the end of the second conveying rod 5. The first action plate 11 contacts the side of the grid cluster, and the second action plate 12 contacts the lower end of the grid cluster. Then, the first slider 7 is fixed, and the second slider 8 moves along the adjusting rod in a direction away from the first slider. During the movement of the second slider 8, the first rotating rod 9 and the connecting plate 10 are rotated. When the first rotating rod 9 and the connecting plate 10 rotate, the first action plate 11 and the second action plate 12 are rotated 90 degrees, so that the first action plate 11 is rotated to a horizontal position and the second action plate 12 is rotated to a vertical position. Figure 5 As shown.
[0045] Example 2
[0046] In some embodiments, such as Figure 6 As shown, the upper and lower ends of the grid cluster 1 are respectively provided with an upper connecting rod 2 and a lower connecting rod 3. When several grid clusters 1 are vertically arranged on the first conveyor rod 4 and the second conveyor rod 5, the upper connecting rod 2 is located at the lower end of the second conveyor rod 5, and the lower connecting rod 3 is located at the upper end of the first conveyor rod 4. Figure 7 As shown, the width of the first action plate 11 and the second action plate 12 is smaller than the width of the two second transmission rods 5.
[0047] When the first action plate 11 and the second action plate 12 rotate 90 degrees, they drive the grid cluster to rotate. The upper end of the grid cluster is connected to the second conveyor rod 5, and the lower connecting rod remains in contact with the first conveyor rod 4. After the grid cluster rotates, the upper connecting rod separates from the second conveyor rod and contacts the first conveyor rod, causing the grid cluster to be placed horizontally. After the grid cluster is placed horizontally on the first conveyor rod 4, as... Figure 8 As shown, the first conveyor rod conveys the grid cluster.
[0048] In some embodiments, after the first action plate 11 and the second action plate 12 are rotated 90 degrees, the first action plate 11 is located below the first transmission rod 4.
[0049] In use, the upper connecting rod 2 of several vertically placed square clusters is placed above the second conveying rod 5, and the lower connecting rod 3 is placed above the first conveying rod 4. In this embodiment, the upper end of the square cluster is in contact with the second conveying rod 5, and the lower end of the square cluster is in contact with the first conveying rod 4. When rotating, the side of the square cluster is in contact with the first working plate 11, and the lower end of the square cluster rotates with the second working plate 12. After rotation, the side of the square cluster that is in contact with the first working plate 11 is in contact with the first conveying rod 4, which facilitates horizontal placement and transmission through the first conveying rod.
[0050] In some embodiments, such as Figure 10 As shown, it includes two adjusting rods 6. The two ends of the first slider 7 and the second slider 8 are respectively connected to the two adjusting rods. The first slider 7 and the second slider 8 can slide on the two adjusting rods. The two ends of the two adjusting rods 6 are respectively connected to the fixing blocks 14. The second slider 8 is connected to one of the fixing blocks 14 by a telescopic rod 13. The second slider 8 slides on the adjusting rod by extending and retracting the telescopic rod 13.
[0051] Example 3
[0052] Based on the above embodiments, the detection mechanism includes a conveyor frame 15 for conveying the square cluster 1, a connecting cover 16 is provided on the conveyor frame 15, and a detection element for detecting silkworm cocoons and a screening element for screening silkworm cocoons are sequentially arranged inside the connecting cover 16 along the conveying direction of the conveyor frame 15. The conveying mechanism is provided with a first cocoon drop outlet for collecting silkworm cocoons.
[0053] like Figure 9 As shown, the screening component includes an adjustable grid plate 17 with the same structure as the grid cluster 1. Each square of the adjustable grid plate 17 corresponds one-to-one with the grid cluster 1, and each square of the adjustable grid plate 17 is equipped with a telescopic rod 18. The detection component includes a camera.
[0054] During operation, as the grid cluster passes through the conveyor, an image of the silkworm cocoons within the cluster is first captured by a camera. The cocoon regions in each image are then divided to obtain multiple local images. Texture is extracted from each local image to obtain a corresponding local texture location map (a binary image). The texture direction of each pixel in the local texture location map is then obtained. Based on the texture direction, the visibility of each pixel in the local texture location map is calculated. Based on the visibility of each pixel, a texture feature index is calculated for each local image. Based on the texture feature index, the quality level of the cocoons in the images is determined, resulting in a corresponding quality level. The location information of cocoons that failed the inspection within the grid cluster is then obtained based on their quality level.
[0055] The conveyor frame 15 continues to convey the square cluster. When the square cluster is directly below the adjusting square plate 17, each square in the adjusting square plate 17 corresponds to a square in the square cluster. Based on the position information of the silkworm cocoons that failed the test in the square cluster, the telescopic rods with the same position information in the adjusting square plate 17 are extended to push the silkworm cocoons that failed the test out of the square cluster and into the first cocoon drop opening.
[0056] The conveyor frame 15 continues to convey the square clusters, placing them on the clustering platform. The cocoon-picking mechanism pushes the cocoons off the square clusters and drops them through the cocoon-dropping opening to obtain the cocoons.
