Description

Technical Field

[0001] This utility model relates to the technical field of shellfish harvesting devices, and in particular to a shellfish harvesting device with screening function. Background Technology

[0002] Currently, the harvesting of pond shellfish in domestic aquaculture mainly relies on manual labor and simple harvesting equipment. This requires workers to spend a lot of time and energy, resulting in low harvesting efficiency, extremely high labor intensity, high sand content, and low survival rate.

[0003] Regarding the aforementioned issue, patent document CN221011562U discloses a benthic mollusk harvesting device, comprising a traction unit, a digging unit, and a harvesting unit. The traction unit drives the digging unit, which includes a digging hook to excavate mollusks buried in the soil. The harvesting unit collects the shells excavated by the digging unit. A warning unit is located below the traction unit at the front end of the traction unit's direction of travel. The warning unit stimulates the mollusks, causing them to close their shells tightly before harvesting to prevent sand inhalation. The beneficial effects of this invention are: a benthic mollusk harvesting device that allows for vertical adjustment of the digging unit via an adjustment mechanism, ensuring the harvesting device adapts to different harvesting environments and increasing its utilization rate.

[0004] The aforementioned patents do not have a screening function and cannot classify shellfish by size. Therefore, we propose a shellfish harvesting device with a screening function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of not having a screening function and being unable to grade shellfish by size, and to propose a shellfish harvesting device with a screening function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shellfish harvesting device with screening function includes:

[0008] Mounting base and track wheels mounted on the mounting base;

[0009] The mounting frame is fixedly installed on the mounting base, and the inner side of the mounting frame is equipped with a conveyor chain plate;

[0010] Two support plates are connected to the mounting base. The two support plates are rotatably mounted on the same rotating shaft. Multiple flaps are fixedly mounted on the outside of the rotating shaft.

[0011] The graded filter box is slidably mounted on the mounting base;

[0012] The flushing mechanism, mounted on the mounting base, is used to flush soil and shellfish;

[0013] The power conversion mechanism, located on the mounting base, is used to drive the conveyor chain, rotating shaft, and grading filter box.

[0014] Preferably, the rinsing mechanism includes a water pump mounted on a mounting base, the water pump being connected to a first rinsing pipe, and the first rinsing pipe being connected to a second rinsing pipe.

[0015] Preferably, the power conversion mechanism includes a mounting box mounted on a mounting base, and a connecting shaft, a first mounting shaft, and a second mounting shaft are rotatably mounted on the mounting box.

[0016] Preferably, a first pulley is fixedly mounted on one end of the first mounting shaft, a second pulley is connected to the conveyor chain plate, a third pulley is rotatably mounted on the mounting frame, a fourth pulley is connected to the rotating shaft, the first pulley and the second pulley are connected to the same first belt, the first pulley and the third pulley are connected to the same second belt, and the third pulley and the fourth pulley are connected to the same third belt.

[0017] Preferably, a first bevel gear is fixedly installed at one end of the connecting shaft, a second bevel gear is fixedly installed at one end of the first mounting shaft, and a third bevel gear is fixedly installed at one end of the second mounting shaft. The first bevel gear meshes with the second bevel gear, and the second bevel gear meshes with the third bevel gear.

[0018] Preferably, two mounting plates are fixedly mounted on the mounting base, and the same rotating rod is rotatably mounted on the two mounting plates. A cam is mounted on the outer side of the rotating rod, and the cam contacts the outer side of the grading filter box.

[0019] Preferably, multiple positioning plates are fixedly installed on the mounting base, and one end of a spring is fixedly installed on each of the multiple positioning plates, with the other end of the spring fixedly connected to one side of the grading filter box.

[0020] Preferably, a fourth bevel gear is fixedly mounted on the other end of the second mounting shaft, and a fifth bevel gear meshes with the fourth bevel gear, which is fixedly mounted on the outside of the rotating rod.

[0021] Compared with the prior art, the advantages of this utility model are:

[0022] In this design, the connecting shaft drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the third bevel gear to rotate. The second bevel gear then drives the first mounting shaft to rotate, which in turn drives the first pulley to rotate. This first pulley, via a first belt and a second belt, drives the second and third pulleys to rotate. The second pulley then drives the conveyor chain to rotate, and the third pulley, via a third belt, drives the fourth pulley to rotate. The fourth pulley then drives the rotating shaft to rotate, which in turn drives the tilting plate to move. This movement, via the third bevel gear, drives the fourth bevel gear to rotate, which in turn drives the fifth bevel gear to rotate. The fifth bevel gear drives the rotating rod to rotate, which in turn drives the cam to rotate. The cam's rotation pushes the grading filter box to move. The spring resets the grading filter box, allowing it to reciprocate. The track wheels move, driving the entire assembly to move. The flip plate flips the soil and shellfish onto the conveyor chain plate. Fine soil flows directly out from the gaps in the conveyor chain plate. The soil and shellfish are then transported to the grading filter box via the conveyor sprocket. The grading filter box grades and screens the shellfish. A water pump draws water, which is sprayed out through the first and second flushing pipes to wash the soil and shellfish on the conveyor chain plate and the grading filter box.

[0023] The gaps between the conveyor chain plates of this utility model allow for primary screening and cleaning of small shellfish. The shellfish and some soil are then conveyed to the subsequent grading filter box, where the shellfish are graded by size. Unqualified shellfish and soil are washed and shaken before returning to the soil below. Attached Figure Description
