Description

Technical Field

[0001] The present invention relates to a wheel-type shellfish picker and a shellfish picking method, belonging to the technical field of fishery machinery, specifically to aquatic machinery, and particularly to a wheel-type shellfish picker. Background Art

[0002] Shellfish are mainly distributed in the ocean, and a very small number of populations live in freshwater lakes. Shellfish growing in the ocean are usually hidden under the sand. It is difficult to find and pick them manually, which is not only time-consuming, labor-intensive, but also inefficient. At present, there is no relatively applicable picking machinery and picking method for marine shellfish. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a wheel-type shellfish picker and a shellfish picking method, which can efficiently pick and collect shellfish in marine sand piles.

[0004] The technical problems to be solved by the present invention are achieved by the following technical solutions:

[0005] A wheel-type shellfish picker for picking shellfish in the seabed sand includes a box body, a rotating shaft, an impeller, a flushing wheel water pipe, and a flushing sand water pipe.

[0006] The bottom of the box body is provided with an opening. The rotating shaft is arranged inside the box body, and both ends of the rotating shaft are rotatably connected to the front and rear side walls of the box body respectively;

[0007] A plurality of impellers for holding shellfish are evenly arranged along the circumferential direction of the rotating shaft. The impeller is provided with sieve holes;

[0008] The flushing wheel water pipe is vertically arranged on the side wall of the box body. The flushing wheel water pipe is used for spraying water and impacting the impeller to make it rotate;

[0009] The flushing sand water pipe is inclinedly arranged at the lower part of the side wall of the box body. The flushing sand water pipe is used for impacting the seabed to make the shellfish come out of the sand and float forward;

[0010] Water suction ports and water inlets are respectively arranged on the front and rear sides of the box body. The water suction port is used for sucking the shellfish from the impeller, and the water inlet is used for supplementing seawater.

[0011] As a preferred example, the flushing wheel water pipe is provided with two groups, upper and lower. One group of parallel flushing wheel water pipes is arranged above one side of the box body and the other group is arranged below the other side. The flushing wheel water pipe is perpendicular to the rotating shaft. The upper flushing wheel water pipe and the lower flushing wheel water pipe both spray water on the impeller to generate a couple moment, so that the impeller rotates.

[0012] As a preferred example, each of the impellers is an L-shaped blade with a bent portion, and the bending direction of the L-shaped blade is consistent with the water flushing direction of the punching wheel water pipe, ensuring that the shellfish can be caught by the impeller.

[0013] As a preferred example, the positions of both ends of the impeller corresponding to the punching wheel water pipe are of a closed structure without sieve holes. The sieve holes on the impeller reduce the resistance during rotation and are also beneficial for sand leakage. No sieve holes are provided in the area facing the punching wheel water pipe, ensuring that the impact force of the seawater on the blade is not weakened.

[0014] As a preferred example, the water suction port and the water inlet are arranged parallel to the impeller, lifting the shellfish to the water suction port, and the water suction port is parallel to the seabed (conventional water suction ports are directly or obliquely facing the seabed). This is beneficial for reducing the intake of sediment and increasing the service life of the pump.

[0015] As a preferred example, the top of the box body is arc-shaped, facilitating the flow of seawater inside the box body and reducing the resistance of the seawater on the impeller during rotation.

[0016] As a preferred example, the number of the sand flushing water pipes increases with the increase of the length of the impeller. The longer the impeller length, the more the number of sand flushing water pipes at the same interval, ensuring that the shellfish on the seabed along the length direction of the impeller can be impacted and floated up and caught by the impeller.

[0017] As a preferred example, a net cover for preventing fish from entering is provided at the water inlet.

[0018] As a preferred example, the water suction port is connected with a net bag for loading shellfish, and the shellfish enter the net bag from the water suction port.

[0019] A method for picking up shellfish by a wheel-type shellfish picker, using the wheel-type shellfish picker as described above. The specific method is as follows: Place the bottom of the box body on the seabed sand. The sand flushing water pipe sprays seawater to impact the seabed sand, causing the shellfish to emerge from the sand and float forward. The punching wheel water pipe sprays seawater to impact the impeller, causing it to rotate around the rotating shaft and catch the shellfish washed out. While the impeller rotates, the sand leaks out through the sieve holes. The water suction port sucks and draws the shellfish in the box body. When sucking, seawater is supplemented from the water inlet.

[0020] The beneficial effects of the present invention are:

[0021] Through the present invention, a wheel-type shellfish picker and a method for picking up shellfish are provided. The sand flushing water pipe sprays seawater to impact the shellfish in the seabed sand, and the punching wheel water pipe sprays seawater to impact the impeller to rotate and catch the impacted shellfish. When the shellfish is driven by the impeller to rotate to the position opposite to the water suction port, the pump at the water suction port sucks the shellfish from the impeller into the net bag, completing the shellfish picking work. The wheel-type shellfish picker of the present invention can replace the existing manual work to pick up shellfish, saving time and effort, not requiring a large amount of manual labor, and having a high picking efficiency.

[0032] In order to clearly understand the technical means, creative features, achieved purposes and effects of the present invention, the present invention will be further described below with reference to specific drawings and embodiments.

[0033] Embodiment 1:

[0034] As Figures 1 - 3 shown, the present invention provides a wheel - type shell collector for picking up shellfish in the seabed sand, including a box body 1, a rotating shaft 2, an impeller 7, a flushing wheel water spray pipe 5 and a flushing sand water spray pipe 6.

[0035] The box body 1 is generally in a rectangular shape. An opening 106 is provided at the bottom of the box body 1, and partitions are provided on the remaining surfaces, including a front side wall 101, a rear side wall 102, a left side wall 103, a right side wall 104, and an upper wall 105. The rotating shaft 2 is installed inside the box body 1, and both ends of the rotating shaft 2 are rotatably connected to the front side wall 101 and the rear side wall 102 on the front and rear sides of the box body 1 respectively. The rotating shaft 2 is connected to the box body 1 through bearings.

[0036] As Figures 4 - 6 shown, a plurality of impellers 7 for holding shellfish are evenly arranged along the circumferential direction of the rotating shaft 2. Sieve holes are formed in the impellers 7. Each impeller 7 is an L-shaped blade with a bent portion 703. The bending direction of the L-shaped blade is the same as the water spraying direction of the punching wheel water spray pipe 5. The two ends of the impeller 7 corresponding to the positions of the punching wheel water spray pipe 5 are in a closed structure without sieve holes. That is, the area on the impeller 7 is divided into a sieve hole area 701 in the middle and closed areas 702 on both sides. The sieve holes on the impeller 7 not only reduce the resistance of rotation but also facilitate sand leakage. The area facing the punching wheel water spray pipe 5 is not provided with sieve holes, which can ensure that the impact force of seawater on the blade is not weakened.

[0037] Punching wheel water spray pipes 5 are vertically arranged on the left side wall 103 and the right side wall 104 of the box body 1. The punching wheel water spray pipes 5 are used for spraying water and impinging on the impellers 7 to make them rotate. There are two sets of punching wheel water spray pipes 5 arranged up and down. A set of mutually parallel punching wheel water spray pipes 5 are provided above the right side wall 104 and below the left side wall 103 of the box body 1 respectively. The punching wheel water spray pipes 5 are perpendicular to the rotating shaft 2. Both the upper punching wheel water spray pipe 5 and the lower punching wheel water spray pipe 5 spray water on the impellers 7 to generate a couple moment, causing the impellers 7 to rotate.

[0038] A sand flushing water spray pipe 6 is inclinedly arranged at the lower part of the right side wall 104 of the box body 1. The sand flushing water spray pipe is inclined towards the seabed. The sand flushing water spray pipe 6 is used for impinging on the seabed to make the shellfish come out of the sand and float forward. The number of sand flushing water spray pipes 6 increases with the increase in the length of the impeller 7. The longer the impeller 7, the more the number of sand flushing water spray pipes 6 at the same interval, ensuring that the shellfish on the seabed along the length direction of the impeller 7 can be impinged and floated up and held by the impellers 7.

[0039] A water suction port 3 and a water inlet 4 are respectively arranged on the rear side wall 102 and the front side wall 101 of the box body 1. The water suction port 3 is used for sucking the shellfish from the impellers 7, and the water inlet 4 is used for supplementing seawater. The shellfish washed out are collected in the impellers 7, improving the suction rate of the suction pipe water suction port 3 for the shellfish. The shellfish are concentrated and close to the water suction port 3, which is beneficial to improving the suction rate of the shellfish, thereby reducing the suction of seawater and reducing the energy consumption of the pump.

[0040] The water suction port 3 and the water inlet port 4 are arranged parallel to the impeller 7. The shellfish are lifted to the water suction port 3, and the water suction port 3 is parallel to the seabed (the conventional water suction port 3 directly faces or obliquely faces the seabed). This is beneficial to reducing the suction of sediment and improving the service life of the pump. A net cover 401 for preventing fish from being sucked in is provided at the water inlet port 4. The water suction port 3 is connected to a net bag for loading shellfish, and the shellfish enter the net bag from the water suction port 3.

[0041] The present invention also provides a method for picking up shellfish by a wheel-type shellfish picker. Using the wheel-type shellfish picker as described above, the specific method is as follows: Place the bottom of the box body 1 on the seabed sand. The sand flushing water spray pipe 6 sprays seawater to impact the seabed sand so that the shellfish come out of the sand and float forward. The impeller flushing water spray pipe 5 sprays seawater to impact the impeller 7 to make it rotate around the rotating shaft 2 and catch the shellfish washed out. While the impeller 7 rotates, the sand leaks out through the sieve holes. The water suction port 3 sucks and draws the shellfish in the box body 1. When sucking and drawing, seawater is supplemented from the water inlet port 4.

[0042] Embodiment 2:

[0043] As Figure 7 shown, the difference from Embodiment 1 is only the shape of the box body 1. In this embodiment, the top of the box body 1 is arc-shaped. Specifically, the top of the box body 1 is arc-shaped, and the bottom is a rectangular body. The arc-shaped structure at the top can facilitate the smooth flow of seawater inside the box body 1 and can reduce the resistance of seawater when the impeller 7 rotates.

[0044] Embodiment 3:

[0045] As Figure 8 shown, similar to the improvement in Embodiment 2, in this embodiment, the box body 1 is integrally a horizontally placed cylinder, and the bottom opening 106 is a side cut of the cylinder. The overall cylindrical structure can facilitate the smooth flow of seawater inside the box body 1 and can reduce the resistance of seawater when the impeller 7 rotates.

[0046] The beneficial effects brought by the present invention are as follows:

[0047] Through the present invention, a wheel-type shellfish picker and a method for picking up shellfish are provided. The sand flushing water spray pipe 6 sprays seawater to impact the shellfish in the seabed sand, the impeller flushing water spray pipe 5 sprays seawater to impact the impeller 7 to rotate, and catches the shellfish washed out. When the shellfish are driven by the impeller 7 to rotate to a position opposite to the water suction port 3, the pump at the water suction port 3 sucks the shellfish out of the impeller 7 and into the net bag, completing the shellfish picking work. The wheel-type shellfish picker of the present invention can replace the existing manual work to complete the shellfish picking work, saving time and effort, not requiring a large amount of manual labor, and having a high picking efficiency.

[0048] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field according to the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
