Description

Technical Field

[0001] This utility model belongs to the technical field of shellfish harvesting equipment, and in particular relates to a small-scale shock-type shellfish harvesting device. Background Technology

[0002] Shellfish aquaculture is one of the leading industries in China's fisheries sector, making a significant contribution to the development of China's fisheries economy. The four-cornered clam, as one of the main farmed economic shellfish, has a wide farming area and high yield. Mudflats are the primary habitat for the four-cornered clam, and the harvesting environment there is extremely harsh. Harvesting is a crucial step in the four-cornered clam farming process; the harvesting methods, efficiency, cost, and effectiveness directly impact the farmed clam yield and profitability.

[0003] Currently, the Chinese utility model patent application filed by our team earlier, with publication number CN223274725U, discloses a shellfish vibration liquefaction harvesting device and its shellfish harvesting equipment. The shellfish vibration liquefaction harvesting device includes a support frame, a vibration harvesting unit, and a vibration drive unit. The vibration harvesting unit includes a lifting plate and several striking plates. The vibration drive unit is located on the support frame and is used to drive several striking plates to lift and vibrate the mudflat bottom sediment to liquefy it, thereby enabling the shellfish in the liquefied mudflat bottom sediment to float to the surface. However, the large-scale collection equipment applied for by our team in the early stage requires an independent heavy-duty support frame, multiple sets of customized transmission components and a large power system. Not only does it occupy a lot of space and is difficult to adapt to narrow collection scenarios such as small mudflats and shallows, but the high degree of component customization and low overall integration also leads to high equipment procurement costs. For small-scale collection needs (such as small-scale aquaculture area harvesting), the existing large-scale devices are difficult to promote due to poor adaptability and high cost. There is an urgent need for a shellfish collection device that is small in size, simple in structure and low in procurement cost to solve the problems of low shellfish collection efficiency, insufficient equipment adaptability and high cost in small scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a small-scale impact-type shellfish harvesting device, which aims to solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] In a first aspect, this application provides a small-scale vibratory shellfish harvesting device, including a traveling component for fixing a shellfish vibratory liquefaction module, a tracked drive vehicle and a shellfish harvesting component respectively provided at the front and rear ends of the traveling component, the tracked drive vehicle being provided with a shellfish collection frame; the shellfish harvesting component includes a trapezoidal bottom plate, a set of parallel side baffles and a temporary storage frame extending upward along the bottom plate, a collection roller provided between the opposite surfaces of the two side baffles, a cover plate provided at the top of the side baffles, and a drive motor provided at the top of the cover plate, the output shaft of the drive motor being connected to the collection roller via a transmission belt.

[0007] In one possible implementation, a conveyor belt is also included, one end of which is located in the temporary storage frame of the shellfish harvesting component and extends upward at an angle to the top of the traveling component and then horizontally to the top of the shellfish collection frame. A support frame for supporting the conveyor belt is provided on the side of the shellfish collection frame near the traveling component.

[0008] In one possible implementation, the cover plate is L-shaped, and a connecting rod is provided at the end of the cover plate near the traveling component. The connecting rod is hinged to the cover plate. The collecting roller is rotatably engaged with the side baffle. A material-pushing plate is provided at equal intervals along the circumferential direction on the outer side of the collecting roller. Multiple striking blocks are provided at the radial outer end of the material-pushing plate. The striking blocks are hinged to the material-pushing plate and are arranged at equal intervals along the axial direction of the collecting roller.

[0009] In one possible implementation, the base plate is composed of a plurality of equally spaced partitions, and a partition plate that matches the shape of the collecting roller is provided at the top of the base plate.

[0010] In one possible implementation, the shellfish harvesting assembly further includes a guide rod with an inverted boss-shaped cross-section, a return spring sleeved on the outside of the guide rod, and a guide rod groove that slides with the guide rod at the bottom end of the side baffle.

[0011] In one possible implementation, a slider is provided on the side baffle near the end of the temporary storage frame, and a groove is provided on the end of the temporary storage frame near the side baffle to slide with the slider.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] This invention integrates a shellfish vibration liquefaction module into a compact traveling component, eliminating the need for a large support structure, thus reducing the size and weight of the device and making it suitable for small-scale collection needs. Then, through the reciprocating motion of the shellfish vibration liquefaction module, the feeding plate, the striking block, and the bottom plate, the shellfish are fully separated from the mud and sand. Finally, the shellfish are automatically transported by a conveyor belt, which reduces the size of the shellfish and lowers the cost while eliminating the need for extensive manual intervention in shellfish collection.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0027] like Figures 1-8 As shown, a small-scale vibratory shellfish harvesting device is described. This small-scale vibratory shellfish harvesting device includes a traveling component 3 for fixing a shellfish vibratory liquefaction module 2. A tracked drive vehicle 1 and a shellfish harvesting component 4 are respectively provided at the front and rear ends of the traveling component 3. The device is characterized in that: a shellfish collection frame 101 is provided on the tracked drive vehicle 1; the shellfish harvesting component 4 includes a trapezoidal bottom plate 401, a set of parallel side baffles 405 and a temporary storage frame 404 extending upward along the bottom plate 401, a collection roller 403 is provided between the opposite surfaces of the two side baffles 405, a cover plate 408 is provided at the top of the side baffles 405, and a drive motor 407 is provided at the top of the cover plate 408. The output shaft of the drive motor 407 is connected to the collection roller 403 through a transmission belt.

[0028] First, use Figure 1 The overall structure of this small-scale vibration-type shellfish harvesting equipment is described. Figure 1 This is an isometric view of one embodiment of this application.

[0029] The small impact-type shellfish harvesting device also includes a conveyor belt 5. One end of the conveyor belt 5 is located in the temporary storage frame 404 of the shellfish harvesting component 4 and extends upward at an angle to the top of the traveling component 3 and then extends horizontally to the top of the shellfish collection frame 101. A support frame for supporting the conveyor belt 5 is provided on the side of the shellfish collection frame 101 near the traveling component 3.

[0030] In this embodiment, both ends of the traveling component 3 are hinged to the tracked drive vehicle 1 and the shellfish harvesting component 4 respectively via connecting rods. The shellfish impact liquefaction module 2 has the same structure as the shellfish impact liquefaction harvesting device with publication number CN223274725U. When working, it can generate high-frequency impact force to act on the mud and sand layer in the collection area, so that the mud and sand are loosened and liquefied, thereby realizing the separation of shellfish and mud and sand.

[0031] The tracked vehicle 1 is located at the front end of the traveling component 3. It adopts a tracked design, which can increase the contact area with the ground and prevent sinking on soft tidal flats. At the same time, it can flexibly cope with terrain protrusions or depressions, providing stable moving power for the entire device. A shellfish collection frame 101 is fixedly installed on the upper part of the tracked vehicle 1. The shellfish collection frame 101 is a frame structure with an open top, used to store shellfish transported by the conveyor belt 5.

[0032] In some embodiments, such as Figure 3 and Figure 5As shown. In this embodiment, the cover plate 408 is L-shaped, and a connecting rod 406 is provided at the end of the cover plate 408 near the traveling component 3. The connecting rod 406 is hinged to the cover plate 408. The collecting roller 403 is rotatably engaged with the side baffle 405. The outer side of the collecting roller 403 is provided with material-pushing plates 408 arranged at equal intervals along the circumference. Multiple striking blocks 409 are provided at the outer radial end of the material-pushing plates 408. The striking blocks 409 are hinged to the material-pushing plates 408 and arranged at equal intervals along the axial direction of the collecting roller 403.

[0033] The material-pushing plate 408 is used to push the shellfish away from the side of the collecting roller 403 near the traveling component 3 and transport them to the temporary storage frame 404. While the collecting roller 403 is rotating, the striking block 409 on the outer end of the material-pushing plate 408 is driven to rotate synchronously. The striking block 409 is hinged to the material-pushing plate 408, so that the striking block 409 can rotate flexibly when it comes into contact with the shellfish, avoiding scratching the shellfish shell. At the same time, the striking block 409 can break up the mud and sand adhering to the surface of the shellfish, further improving the purity of the shellfish.

[0034] In some embodiments, such as Figure 3 and Figure 4 As shown. In this embodiment, the base plate 401 is composed of a plurality of equally spaced partitions, and a material separating plate 402 that matches the shape of the collecting roller 403 is provided at the top of the base plate 401.

[0035] The bottom plate 401 has a trapezoidal cross-section, which guides the harvested shellfish to move naturally towards the collecting roller 403 along the inclined surface, preventing the shellfish from accumulating and clogging on the surface of the bottom plate 401. At the same time, the bottom plate 401 is composed of multiple equally spaced partitions, and the gaps between the partitions allow excess mud and sand to leak out, reducing the amount of mud and sand mixed in with the shellfish. At the top of the bottom plate 401, there is also a partition plate 402. The shape of the partition plate 402 matches the shape of the collecting roller 403 and can fit against the surface of the striking block 409, so that the shellfish are isolated from the area of ​​the collecting roller 403 after passing the partition plate 402, ensuring the continuity of the harvesting process.

[0036] In some embodiments, such as Figures 6-7 As shown. In this embodiment, the shellfish harvesting assembly 4 also includes a guide rod 411 with an inverted boss-shaped cross-section, a return spring 412 sleeved on the outside of the guide rod 411, and a guide rod groove 410 that slides with the guide rod 411 at the bottom end of the side baffle 405.

[0037] When the collecting roller 403 drives the striking block 409 to rotate, it impacts the base plate 401, which is composed of multiple equally spaced partitions, forcing the partitions to move downwards. The guide rod 411, which is fixedly connected to the partitions, can move downwards along the guide rod groove 410. When the striking block 409 moves away from the partitions, the partitions move upwards under the action of the return spring 412, so that the partitions reciprocate during the operation of the collecting roller 403, thereby causing the mud and sand to be quickly separated.

[0038] In some embodiments, such as Figure 8 As shown. In this embodiment, a slider 413 is provided at the end of the side baffle 405 near the temporary storage frame 404, and a groove 414 is provided at the end of the temporary storage frame 404 near the side baffle 405 to slide and engage with the slider 413.

[0039] The material separator 402 is located between the side baffles 405. When the collecting roller 403 drives the striking block 409 to rotate and strike the bottom plate 401, it will also drive the side baffles 405 to move up and down. When the side baffles 405 are close to the slider 413 at the end of the temporary storage frame 404, the stability of the temporary storage frame 404 relative to the ground is improved.

[0040] Finally, an arc-shaped stop block that matches the shape of the conveyor belt 5 is provided inside the temporary storage frame 404 near the side of the partition plate 402.

[0041] The travel assembly 3 includes a travel mounting plate, and a battery or diesel generator electrically connected to the shellfish impact liquefaction module is provided at the top of the travel mounting plate.

[0042] The travel assembly 3 includes a set of axles arranged in parallel below the travel mounting plate. Each axle is equipped with a wheel at its connecting end. A support sleeve that rotates with the axle is fitted on the outside of the axle. A support link extending to the travel mounting plate is provided on the outside of the support sleeve.

[0043] In this embodiment, during operation, the tracked drive vehicle 1 is started, driving the entire device to move to the preset shellfish collection area. During this process, the two ends of the traveling component 3 are hinged to the tracked drive vehicle 1 and the shellfish collection component 4 respectively through connecting rods.

[0044] Upon reaching the collection area, the shellfish vibration liquefaction module 2, which is fixed on the traveling component 3, is activated. During operation, it generates high-frequency vibration force and acts on the mud and sand layer in the collection area, causing the mud and sand to loosen and liquefy, thereby achieving the initial separation of shellfish from mud and sand, creating conditions for the subsequent harvesting operation of the shellfish harvesting component 4.

[0045] Subsequently, the drive motor 407 at the top of the cover plate 408 in the shellfish harvesting component 4 is activated. The output shaft of the drive motor 407 transmits power to the collecting roller 403 through the transmission belt, causing the collecting roller 403 to rotate on its own shaft. This also causes the outer material-pushing plate 408 of the collecting roller 403 to rotate synchronously, pushing the shellfish separated after being processed by the shellfish vibration liquefaction module 2 from the side of the collecting roller 403 near the traveling component 3 into the shellfish harvesting component 4. At the same time, the striking block 409 on the outer side of the material-pushing plate 408 rotates synchronously with the collecting roller 403. Because the striking block 409 is hinged to the material-pushing plate 408, the striking block 409 can rotate flexibly when it comes into contact with the shellfish, which not only avoids scratching the shellfish shells but also disperses the mud and sand adhering to the surface of the shellfish, further improving the purity of the shellfish.

[0046] The feeding plate 408 moves the shellfish toward the separating plate 402, preventing them from accumulating and clogging on the surface of the bottom plate 401. The bottom plate 401 is composed of multiple equally spaced separating plates, and the gaps between the separating plates allow excess mud and sand to leak out, reducing the amount of mud and sand mixed in with the shellfish. At the same time, the separating plate 402 is matched with the shape of the collecting roller 403 and fits against the surface of the striking block 409, ensuring that the shellfish are isolated from the area of ​​the collecting roller 403 after passing the separating plate 402, thus ensuring that the harvesting process is continuous and uninterrupted.

[0047] During the rotation of the collecting roller 403 and the striking block 409, the striking block 409 will strike the partition of the bottom plate 401, forcing the partition to move downward. The guide rod 411, which is fixedly connected to the partition, will slide downward along the guide rod groove 410 in the side baffle 405. When the striking block 409 moves away from the partition, the return spring 412 sleeved on the outside of the guide rod 411 will restore its deformation, causing the guide rod 411 to slide upward along the guide rod groove 410, thereby causing the partition to move up and down reciprocally, accelerating the separation of mud and sand from the gap between the partitions, and further reducing the sand content of the shellfish.

[0048] At the same time, the impact of the striking block 409 on the bottom plate 401 will also cause the side baffle 405 to move up and down. The slider 413 of the side baffle 405 near the end of the temporary storage frame 404 slides along the groove 414 on the corresponding side of the temporary storage frame 404. Through the sliding cooperation between the slider 413 and the groove 414, the temporary storage frame 404 is kept stable relative to the ground when the side baffle 405 moves, so as to avoid the temporary storage frame 404 shaking and affecting the shellfish receiving.

[0049] The shellfish separated by the feeding plate 408 are finally transported to the temporary storage frame 404, where the shellfish are temporarily stored. Then, the shellfish in the temporary storage frame 404 are scraped up by the conveyor belt 5 with the cooperation of the conveyor belt 5 and the arc-shaped stop. Subsequently, the shellfish are driven by the conveyor belt 5 to pass through the inclined section and the horizontal section in sequence, and finally fall into the shellfish collection frame 101 on the tracked drive vehicle 1, completing a complete shellfish collection process.

[0050] When the shellfish in the shellfish collection box 101 reaches the preset capacity, turn off the drive motor 407 and the shellfish vibration liquefaction module 2, start the tracked drive vehicle 1 to move the device to the shellfish transfer area, dump the shellfish in the shellfish collection box 101, and then move the device to a new collection area again to repeat the above process for the next round of shellfish collection.

[0051] Example 2

[0052] This utility model embodiment also provides a small-scale vibratory shellfish harvesting device, including a traveling component 3 for fixing the shellfish vibratory liquefaction module 2, and a tracked drive vehicle 1 and a shellfish harvesting component 4 respectively provided at the front and rear ends of the traveling component 3. The device is characterized in that: the tracked drive vehicle 1 is provided with a shellfish collection frame 101; the shellfish harvesting component 4 includes a trapezoidal bottom plate 401, a set of parallel side baffles 405 and a temporary storage frame 404 extending upward along the bottom plate 401, a collection roller 403 is provided between the opposite surfaces of the two side baffles 405, a cover plate 408 is provided at the top of the side baffles 405, and a drive motor 407 is provided at the top of the cover plate 408. The output shaft of the drive motor 407 is connected to the collection roller 403 through a transmission belt. When working, the tracked drive vehicle 1 is started, driving the entire device to move to the preset shellfish collection area. During this process, the two ends of the traveling component 3 are hinged to the tracked drive vehicle 1 and the shellfish harvesting component 4 respectively through connecting rods.

[0053] Upon reaching the collection area, the shellfish vibration liquefaction module 2, which is fixed on the traveling component 3, is activated. During operation, it generates high-frequency vibration force and acts on the mud and sand layer in the collection area, causing the mud and sand to loosen and liquefy, thereby achieving the initial separation of shellfish from mud and sand, creating conditions for the subsequent harvesting operation of the shellfish harvesting component 4.

[0054] Subsequently, the drive motor 407 at the top of the cover plate 408 in the shellfish harvesting component 4 is activated. The output shaft of the drive motor 407 transmits power to the collecting roller 403 through the transmission belt, causing the collecting roller 403 to rotate on its own shaft. This also causes the outer material-pushing plate 408 of the collecting roller 403 to rotate synchronously, pushing the shellfish separated after being processed by the shellfish vibration liquefaction module 2 from the side of the collecting roller 403 near the traveling component 3 into the shellfish harvesting component 4. At the same time, the striking block 409 on the outer side of the material-pushing plate 408 rotates synchronously with the collecting roller 403. Because the striking block 409 is hinged to the material-pushing plate 408, the striking block 409 can rotate flexibly when it comes into contact with the shellfish, which not only avoids scratching the shellfish shells but also disperses the mud and sand adhering to the surface of the shellfish, further improving the purity of the shellfish.

[0055] The feeding plate 408 moves the shellfish toward the separating plate 402, preventing them from accumulating and clogging on the surface of the bottom plate 401. The bottom plate 401 is composed of multiple equally spaced separating plates, and the gaps between the separating plates allow excess mud and sand to leak out, reducing the amount of mud and sand mixed in with the shellfish. At the same time, the separating plate 402 is matched with the shape of the collecting roller 403 and fits against the surface of the striking block 409, ensuring that the shellfish are isolated from the area of ​​the collecting roller 403 after passing the separating plate 402, thus ensuring that the harvesting process is continuous and uninterrupted.

[0056] During the rotation of the collecting roller 403 and the striking block 409, the striking block 409 will strike the partition of the bottom plate 401, forcing the partition to move downward. The guide rod 411, which is fixedly connected to the partition, will slide downward along the guide rod groove 410 in the side baffle 405. When the striking block 409 moves away from the partition, the return spring 412 sleeved on the outside of the guide rod 411 will restore its deformation, causing the guide rod 411 to slide upward along the guide rod groove 410, thereby causing the partition to move up and down reciprocally, accelerating the separation of mud and sand from the gap between the partitions, and further reducing the sand content of the shellfish.

[0057] At the same time, the impact of the striking block 409 on the bottom plate 401 will also cause the side baffle 405 to move up and down. The slider 413 of the side baffle 405 near the end of the temporary storage frame 404 slides along the groove 414 on the corresponding side of the temporary storage frame 404. Through the sliding cooperation between the slider 413 and the groove 414, the temporary storage frame 404 is kept stable relative to the ground when the side baffle 405 moves, so as to avoid the temporary storage frame 404 shaking and affecting the shellfish receiving.

[0058] The shellfish separated by the feeding plate 408 are finally transported to the temporary storage frame 404, where the shellfish are temporarily stored. When the shellfish in the shellfish collection frame 101 reaches the preset capacity, the drive motor 407, the shellfish vibration liquefaction module 2, and the tracked drive vehicle 1 are turned off. Then, after the workers take the shellfish out of the collection frame 101, the drive motor 407, the shellfish vibration liquefaction module 2, and the tracked drive vehicle 1 can be restarted to repeat the above process for the next round of shellfish collection.
