Description

Technical Field

[0001] This invention relates to the field of silkworm rearing equipment technology, specifically a portable automatic cocoon harvesting machine with a downward pressing and upward lifting mechanism. Background Technology

[0002] China is the birthplace of silk and the world's earliest country to cultivate mulberry trees, raise silkworms, reel silk, and weave silk fabrics. Silkworms have a wide range of uses; however, their rearing process is very complex. Their growth involves several molts, and their stages can be divided into the juvenile stage, the mature silkworm stage, and the dormant stage. Adult silkworms spin cocoons. Mature silkworms are placed in special containers or on cocooning frames, where they then spin silk and form their own cocoons.

[0003] The cocoon-collecting devices previously applied for by the inventor (Patent 1 - 201930433784.0, Cocoon-collecting Device 2 - 201930433788.9, Cocoon-collecting Device 3 - 201930433789.3, and Cocoon-collecting Device 4 - 201930433790.6) were found to be covered with silkworm cocoons during use. Currently, these cocoons are mostly removed manually one by one. To address the problem of tedious cocoon removal, in conjunction with the previously applied patents, the inventor designed a downward-pressing portable cocoon-collecting device with patent number 202321459809.1. However, during use, the separation of the cocoon ejection device from the cocoon-collecting device requires manual operation, which is time-consuming and labor-intensive. The waste silk used to fix the cocoons between the cocoons and the tufting device cannot be drawn into thread and needs to be removed manually, which adds extra workload to the subsequent drawing process. Therefore, it is necessary to design a device to quickly separate the cocoons from the tufting device, and at the same time remove the waste silk in advance to ensure the cleanliness of the cocoons.

[0038] like Figures 1-9 As shown, a portable automatic cocoon harvesting machine with a downward-pressing and upward-lifting design includes: a device support frame 1, a cocoon harvesting operation platform 2 on the device support frame 1, a cocoon harvesting operation platform 2 with a clustering tool placement groove in the middle, a clustering tool 4 placed in the clustering tool placement groove, a cocoon ejection plate 3 on the lower side of the clustering tool placement groove, the cocoon ejection plate 3 being mounted on an ejection drive plate 7, an ejection plate limiting protrusion on the clustering tool placement groove, and a clustering tool clamping frame 5 at one end of the cocoon harvesting operation platform 2.

The protective side plate is installed on the equipment support frame 1 through fixing bolts.

[0039] The working principle of this invention is as follows:

[0040] In use, the cluster clamping frame 5 is lifted by operating handle 55. The cluster clamping frame 5 is linked by the drive plates I92 at both ends of the drive rod I91. The drive plate I92 drives the transmission plate II96 on the ejection drive plate 7 to move down through the linkage plate 93 at the lower end and the right angle transmission plate 95. Then the cocoon ejection plate 3 is moved out of the cluster placement slot. When the ejection drive plate 7 moves down to the lowest end, the clamping spring II106 pushes the release control rod 101 into the control through hole 103 on the elastic control plate 102, controlling the ejection drive plate 7 to remain stationary. At this time, the clamping drive spring 12 of the ejection drive device 10 is in the clamped state. Then the cluster 4 full of cocoons is placed into the cluster placement slot on the cocoon harvesting operation platform 2.

[0041] Then, the cluster clamping frame 5 is pressed down by operating handle 55. During the pressing process, the cluster clamping frame 5 fixes the cluster 4 in the cluster placement slot on the operating platform 2. As the cluster clamping frame 5 continues to press down, the cluster clamping frame 5 drives the ejection trigger rod 99 to trigger the trigger protrusion 105. The trigger protrusion 105 drives the release control rod 101 to move out of the control through hole 103 on the elastic control plate 102. Then, the ejection drive plate 7 moves upward under the drive of the ejection drive device 10. The cocoon ejection plate 3 ejects the cocoons on the cluster 4. Then, the cocoon scraping toothed plate 62 on the sliding cocoon scraping device 6 collects the cocoons in the cocoon collection box next to it.

[0042] Afterwards, the cluster clamping frame 5 is lifted by operating handle 55. The cluster clamping frame 5 is linked by the drive plates I92 at both ends of the drive rod I91. The drive plates I92 drive the transmission plate II96 on the ejection drive plate 7 to move down through the linkage plate 93 and the right angle transmission plate 95 at the lower end. Then, the cocoon ejection plate 3 is moved out of the cluster placement slot, and the cocoon ejection plate 3 is separated from the cluster 4. Afterwards, the cluster 4 with waste silk is placed in a cleaning solution containing protease for cleaning. This cycle can quickly achieve cocoon picking while ensuring that there is less waste silk on the cocoon.

[0043] The present invention is designed so that the cocoon ejection plate 3 is activated only after the cluster clamping frame 5 has clamped the cluster, which ensures overall operational safety and cocoon ejection efficiency. At the same time, the cocoon ejection plate can be detached when the cluster clamping frame 5 is lifted, which can reduce the cocoon harvesting time and improve production efficiency by 50-70% compared with the technology with patent number: 202321459809.1.

[0044] This invention, through the ingeniously designed ejection linkage device 9, enables the connection and separation between the cocoon ejector and the cocoon ejection plate through purely mechanical linkage. During use, only the operating handle needs to be operated, making it very simple to use. Moreover, the purely mechanical structure does not require the use of electric or pneumatic equipment, eliminating the need for haphazard wiring and power supply, thus ensuring a safe operating environment and process, maximizing user safety, and reducing energy costs. This makes the overall production activity energy-saving and environmentally friendly. Furthermore, it allows for rapid cocoon harvesting while minimizing waste silk on the cocoons.
