Description

Technical Field

[0001] The invention belongs to the technical field of fishery machinery, and in particular relates to a multifunctional shellfish harvester and a method thereof. Background Art

[0002] As people's living standards improve, the demand for seafood products continues to increase. This demand growth provides a broad space for the development of the shellfish harvesting market. However, the traditional way of catching and collecting shellfish is to rely on manual digging by staff. Due to the short working time limit, each capture and collection requires a large amount of human resources. For example, a worker can only dig about 50 kilograms of scallops a day, resulting in a high cost of capture and collection. Due to the dual reasons of short working time limit and large manpower input, scallop capture and collection is difficult and inefficient. The work is time-consuming, laborious, and troublesome, making the overall efficiency of shellfish harvesting low. Compared with traditional manual harvesting, the use of mechanized shellfish harvesters can reduce labor costs and increase the harvesting speed. However, in the development of mechanized shellfish harvesting, the technology of some mechanized shellfish harvesting equipment is still immature. For example, digging equipment may have the problem of fixed tillage depth and different shellfish lurking depths, resulting in a high rate of missed shellfish and shellfish injury, resulting in many qualified shellfish not being harvested in time or the harvested shellfish being seriously damaged. This is not conducive to protecting the sustainable development of shellfish resources and improving product quality. Summary of the invention

Turning on the nozzle 48 can achieve the flushing of shellfish with mud and sand.

[0051] Based on the above multifunctional shellfish harvester, the present invention also provides a shellfish harvesting method, which is specifically as follows:

[0052] Before the harvester starts working, the working distance of the spiral disturbance rod 28 and the digging shovel 31 in the vertical direction is changed by the telescopic effect of the front hydraulic push rod 35 in the adjustment device 5, so as to facilitate the harvesting of tidal flat shellfish.

[0053] When the harvester is in operation, the base 1 is driven to move and turn in the tidal flat by the traveling device. The first power device 2 drives the spiral disturbance rod 28 through the first transmission device 4 to stir and dilute the sand, and the rotating spiral disturbance rod stirs the shellfish with mud and sand to the surface of the tidal flat. The digging shovel 31 digs up the shellfish with mud and sand from the surface of the tidal flat. The second power device 8 drives the triangular sliding frame 33 to move inside the digging shovel 31 through the second transmission device 9, and the triangular sliding frame 33 drives the sliding plate 34 to move back and forth. The moving sliding plate 34 moves the shellfish with mud and sand in the digging shovel 31 into the double arc vibration lifting device 67. At the same time, a large amount of mud and sand leaks out through the quicksand outlet 32 ​​below the digging shovel 31.

[0054] Specifically, in this embodiment, the second power device 8 drives the crank shaft 45 to rotate through the second transmission device 9, the crank shaft 45 drives the crank 44 to rotate, the crank 44 drives the connecting rod center rod 43 to rotate, the connecting rod center rod 43 drives the triangular sliding frame 33 to move in the grooves on both sides of the excavating shovel 31, the triangular sliding frame 33 drives the sliding plate 34 to move back and forth, and the moving sliding plate 34 moves the shellfish with mud and sand to the double arc vibration lifting device 67, and at the same time a large amount of mud and sand leaks out through the quicksand outlet 32 ​​below the excavating shovel 31.

[0055] The second power device 8 drives the first rotating hub 64 and the second rotating hub 65 to rotate through the third transmission device 10. During the rotation process, shellfish that are smaller than the required size and do not meet the standards leak out from the drainage port 66, and shellfish that meet the standards are moved to the arc-shaped transport frame 62 through the first rotating hub 64 and the second rotating hub 65. The rear hydraulic cylinder 38 drives the rear hydraulic push rod 37 to drive the lever 61 and the rake claw 70 to move left and right in the arc-shaped transport frame 62. At the same time, the cleaning device 19 is turned on. The cleaning device sprays water on the shellfish in the arc-shaped transport frame 62 through the nozzle 48. With the flushing of the cleaning device 19, a large amount of mud and sand in the shellfish is washed away. After the cleaning is completed, the shellfish that meet the standards are moved toward the transition box 63 through the lever 61, and the shellfish are sent into the transition box 63 through the rake claw 70. After the impurity removal effect of the V-shaped groove 69 in the transition box 63, they slide into the collection box 50 below, completing the shellfish harvesting.

[0056] The present invention achieves the effects of continuous digging, conveying, cleaning, sorting and collecting shellfish, overcomes the technical defect of the prior art that it cannot work continuously, and thus further increases the work efficiency.

A person skilled in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
