Description

Technical Field

[0001] This utility model relates to an intelligent integrated harvesting and desliming device for artificially cultured razor clams, which is mainly used in photovoltaic power generation systems constructed in ecologically sensitive areas such as ecological wetlands and reclaimed water utilization projects. Background Technology

[0002] Razor clams are an important economic shellfish in my country's coastal areas, and their artificial cultivation scale continues to expand, encompassing both clam paddy field farming and tidal flat farming. However, the harvesting process in clam paddy field farming has long relied on manual digging, presenting significant industry pain points: First, it is labor-intensive and inefficient, requiring workers to bend over, with an average daily harvest area of ​​less than 0.3 mu per person. Furthermore, it is subject to weather factors such as tides, high temperatures, and rain, resulting in poor operational continuity. Second, it is highly dependent on manpower, leading to rising costs. The shortage of labor in aquaculture in coastal areas is becoming increasingly prominent, with labor costs increasing year by year. First, the cost of harvesting razor clams is high because traditional harvesting methods require a large amount of manpower per acre of clam field. Second, existing machinery has poor adaptability. Some tidal flat shellfish harvesting machines use traditional tracked walking structures, which are prone to slipping and getting stuck in the muddy environment of clam fields with a water content of over 65% due to the heavy tracks and high ground pressure. Third, most machines are limited in function and easily damage clam bodies or farming facilities. They only have basic "digging-conveying" functions and lack targeted mud removal designs, resulting in a mud content of over 30% on the surface of the razor clams and high subsequent cleaning costs.

[0003] Therefore, there is an urgent need to develop an intelligent razor clam harvesting equipment that is adaptable to both muddy and net-laying aquaculture scenarios, integrates "harvesting-mud removal-walking" functions, and minimizes damage, in order to overcome the current predicament in the industry.

[0014] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model.

[0015] Figure 2 and Figure 3 These are partial structural schematic diagrams of embodiments of this utility model. Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0017] This utility model embodiment includes a collection unit 1, a conveying unit 2, a cleaning unit 3, and a walking unit 4.

[0018] The collection unit 1 includes a collection unit support 11 and a conveyor 12. The collection unit support 11 is made of 304 stainless steel. The conveyor 12 is a screw conveyor. The function of the conveyor 12 is to transport the razor clams and mud-sand mixture in the mudflats by rotation. The conveyor 12 is installed on the collection unit support 11. Its screw shaft has a pitch of 120mm, an inner diameter of 180mm, and a helix angle of 18°. When the screw shaft rotates, it can uniformly disturb the mud-sand layer 5-10cm deep on the surface of the mudflats. The razor clam and mud-sand mixture is sucked in through the inlet of the conveyor 12. Compared with manual digging, the razor clam capture rate is increased by more than 40%, and the damage rate of razor clams is greatly reduced. The conveyor 12 is equipped with a 1kW power motor, which drives the screw shaft to rotate through the output torque, thereby realizing the transportation of mud, sand and razor clams. At the same time, the screw shaft is made of aluminum alloy, which greatly reduces wear during mudflat operations and effectively ensures the long-term performance of the equipment.

[0019] Conveying unit 2 is arranged along the length of the main frame, connecting collection unit 1 and the rear cleaning unit to ensure a continuous material transfer path. Conveying unit 2 includes a conveying unit support 21, an elevator 22, and a telescopic rod 23. The elevator 22 consists of a speed-regulating motor (0.75kW power, with a reducer reduction ratio of 1:20), a stainless steel mesh belt (6mm×6mm mesh size, 280mm width), and an aluminum alloy support. The mesh belt is tensioned by a drive roller and a driven roller. The upper end of the elevator 22 is rotatably mounted on the conveying unit support 21, and the lower end is fixed to the collection unit support 11. The inlet of the elevator 22 is connected to the outlet of the conveyor 12. One end of the telescopic rod 23 is hinged to the top of the conveying unit support 21, and the other end is hinged to the elevator 22, allowing adjustment of the elevator 22's tilt angle (15° to 40°). During operation, the elevator 22 receives the mixture from collection unit 1 and transfers it to a higher position; the telescopic rod 23 adjusts its tilt angle in real time according to the slope of the clam field to ensure no material accumulation.

[0020] The cleaning unit 3 includes a cleaning unit support 31, a vibration motor 32, a screen 33, a spring assembly 34, and a collection box 35.

[0021] A screen 33 is suspended from the cleaning unit bracket 31 by a spring assembly 34. The screen 33 is made of 304 stainless steel, with a mesh size of 12mm × 12mm and an inclination angle of 12°. The inlet of the screen 33 is connected to the outlet of the elevator 22. The screen 33 is inclined with a higher inlet and a lower outlet. A vibration motor 32 is mounted on the cleaning unit bracket 31, with a power of 0.37kW and a vibration frequency of 50Hz. The vibration motor 32 is connected to the screen 33 through an eccentric block, and drives the screen 33 to reciprocate (amplitude 5mm). The vibration causes the razor clams to move and rub against each other on the screen 33, thereby removing the mud from the razor clams. A collection box 35 is slidably mounted on the cleaning unit bracket 31 via a guide rail. The collection box 35 is made of PE material, has a volume of 60L, and has an overall box structure with an opening at the top. The collection box 35 is connected to the outlet of the screen 33 and collects the razor clams that fall after cleaning. During operation, the vibration motor 32 is started, which drives the screen 33 to vibrate. Under the action of vibration, the razor clams on the screen 33 move continuously and rub against each other, gradually removing the mud from their bodies. The mud and sand leak out through the mesh, and the razor clams slide towards the lower end as the screen 33 vibrates. In this process, preliminary surface desliming is achieved (desliming rate ≥85%). The razor clams after the mud is removed fall into the collection box 35. After cleaning is completed, the collection box 35 can be removed from the cleaning unit bracket 31.

[0022] The traveling unit 4 includes a traveling trolley 41 and a mud skid 42. The conveying unit bracket 21 of the conveying unit 2 and the cleaning unit bracket 31 of the cleaning unit 3 are both mounted on the traveling trolley 41 of the traveling unit 4. The traveling wheels of the traveling trolley 41 are impellers with a 60° angle between the blades. This effectively reduces damage to the artificial clam farming area and prevents damage to the clam farming netting caused by sharp impeller angles, increasing the economic and practical value of the entire area. Simultaneously, the impeller's strong throughput capacity effectively transports liquids containing particles and fibers, preventing them from getting stuck in muddy environments and ensuring smooth operation. The impeller is made of wear-resistant rubber, with a diameter of 400mm (20cm from the center to the highest point), and has four arc-shaped blades with a 30° inclination angle. This size design allows for precise control of the impeller's operating height, preventing contact between the impeller and the farming netting in the mud during netting farming, effectively eliminating netting damage. The mud sled 42 is mounted on the traveling trolley 41. Due to its wide base and raised front end, the mud sled 42 better distributes weight and adapts to complex environments. It also reduces the contact pressure between the trolley and the field ridges or mudflats, preventing it from sinking. During operation, the motor of the traveling trolley 41 drives the impeller to rotate. The blades agitate the silt, generating thrust to propel the equipment forward and simultaneously accelerating silt drainage. The mud sled 42, working in conjunction with the impeller, improves the equipment's maneuverability by 80% in clam fields with a 70% moisture content and in net-laying aquaculture environments, eliminating the risk of slipping and getting stuck.

[0023] During operation, the following parameters are set: conveyor 12 motor speed 180 r / min, inlet suction depth 8 cm; elevator 22 mesh belt speed 0.6 m / s, telescopic rod adjustment tilt angle 25°; screen 33 vibration frequency 50 Hz, amplitude 5 mm; traveling trolley 41 motor speed 120 r / min, forward speed 0.4 m / s. After the equipment starts, the traveling unit 4 drives the equipment forward along the clam field furrows. The collection unit 1 sucks in the clam-mud mixture, which is then transferred to the cleaning unit 3 via the conveying unit 2. After vibration and mud removal, the clam slides into the collection box. When the collection box is full, the machine stops, the collection box is pulled out to unload, and the operation continues after replacing the empty box.

[0024] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent.
