Description

Technical Field

[0001] This invention belongs to the field of fishery machinery technology, specifically relating to an air-blowing shellfish seeding device and its seeding method. Background Technology

[0002] Mudflat shellfish are an important species for marine aquaculture in my country, generally living in shallow seas and intertidal mudflats. They have high edible and economic value, and seeding is a crucial step in shellfish aquaculture, closely related to subsequent cultivation and harvesting. Currently, the main method of seeding shellfish is for workers to scatter seedfish onto the mudflat surface. This method suffers from high labor costs, high seedfish breakage rate, low seeding efficiency, and high seeding costs. While there are devices that can seed shellfish, such as the portable wind-blown shellfish seeding machine (publication number CN213404549U), which has only one seeding port and low seeding efficiency, and the automated shellfish seeding device (publication number CN111109169A), which improves seeding efficiency, is large, complex, and costly to manufacture. Therefore, there is a need for a shellfish seeding device that can replace manual seeding, has a simple structure, and low manufacturing cost. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and to propose an air-blowing shellfish seeding device and its seeding method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The present invention provides an air-blowing shellfish seeding device, comprising a seedling box, a seedling discharge mechanism, a seedling blowing mechanism, a cleaning mechanism, and a frame.

[0006] The seedling box is fixed to the frame. The seedling feeding mechanism is located directly below the seedling box and includes a seedling feeding assembly, a rotating shaft, and a seedling separating plate assembly. The seedling feeding assembly has multiple seedling feeding components arranged equidistantly in the horizontal direction, including a seedling feeding pipe, a shell, and a seedling guide pipe. The vertically arranged seedling feeding pipe is fixed at both ends to the seedling box and the shell, and the inner cavity of the shell is connected to the inner cavity of the seedling box through the seedling feeding pipe. The upper end of the seedling guide pipe is fixed to the shell. The horizontally arranged rotating shaft passes through a pair of holes opened in each shell and forms a rotating pair with the frame, and is driven by a motor. A seedling separating plate assembly is provided on the rotating shaft at each position in the inner cavity of each shell. The seedling separating plate assembly consists of 2n seedling separating plates arranged equidistantly in the circumferential direction, where n≥2. The seedling separating plates are fixed on the rotating shaft and arranged in the radial direction. Each seedling separating plate assembly divides the corresponding inner cavity of the shell into 2n seedling separating chambers. The diameter of the seedling feeding pipe and the seedling guide pipe is smaller than the distance between the ends of two adjacent seedling separating plates away from the rotating shaft.

[0007] The seedling blowing mechanism includes a blower, a solenoid valve, an air guide pipe, and a seedling blowing pipe. The blower is fixed on the seedling box, and the blower's exhaust port 1 is connected to the air inlet 1 of the solenoid valve fixed on the frame through the exhaust pipe. The exhaust port 2 of the solenoid valve is connected to the air inlet 2 of the air guide pipe. The air guide pipe is horizontally fixed on the frame, and the end of the air guide pipe away from the solenoid valve is closed. Multiple exhaust ports 3 are equidistantly arranged along the axial direction on the air guide pipe. Each exhaust port 3 is fixed with a downwardly inclined seedling blowing pipe, and each seedling blowing pipe is connected to the air guide pipe. The lower end of each seedling guide pipe is fixed to the middle of a seedling blowing pipe. The inner cavity of each shell is connected to each seedling blowing pipe through each seedling guide pipe, and a photoelectric sensor is provided in the middle of each seedling blowing pipe.

[0008] The cleaning mechanism includes a water tank, a water pipe, nozzles, and valves. The water tank is fixed on the frame, and the outlet of the water tank is connected to the inlet of the water pipe through the valve. The shape of the water pipe is consistent with the shape of the opening at the top of the seedling box, and the water pipe is fixed on the opening. Multiple nozzles are fixed on the water pipe and are equidistantly arranged along the circumference of the opening. Each nozzle is connected to the water pipe.

[0009] Preferably, the lower end of the seedling box has multiple seedling discharge holes arranged at equal intervals, and two seedling separation baffles arranged in a V-shape are fixed on both sides of each seedling discharge hole, and the two seedling separation baffles between every two adjacent seedling discharge holes are combined into an arched baffle; each seedling discharge pipe is fixed to one seedling discharge hole.

[0010] More preferably, both the seedling divider and the seedling divider are made of rubber.

[0011] Preferably, the motor housing is fixed to the frame, and the motor output shaft is connected to the rotary shaft via a coupling.

[0012] Preferably, the rotary shaft is supported on the frame by a bearing housing.

[0013] Preferably, a brush is fixed to the end of the seedling separating board away from the rotating shaft.

[0014] Preferably, the seedling guide tube is equipped with a pipe vibrator.

[0015] More preferably, the frame is equipped with a touch screen, and the controller communicates with the touch screen to control the solenoid valve, valve, pipe vibrator, fan and motor.

[0016] The present invention discloses a seeding method for a pneumatic shellfish seeding device, the specific details of which are as follows:

[0017] Water is filled into the storage tank. The controller opens the valve and drives the motor to rotate the shaft one revolution. Water flows into the water pipes and is sprayed onto the inner wall of the seedling box by each nozzle. It then enters each housing through each seedling discharge pipe, and then enters each blower pipe through each seedling guide pipe. Finally, it flows out from the outlet of each blower pipe. The water flow washes away impurities from the seedling box, each seedling discharge pipe, each housing, each seedling guide pipe, each blower pipe, and each seedling separating plate. A layer of water film is formed on the inner wall of the seedling box, each seedling discharge pipe, each housing, each seedling guide pipe, each blower pipe, and the surface of each seedling separating plate. After the rinsing is completed, the controller closes the valve and stops the motor.

[0018] The frame is mounted on a mobile trolley, which drives the frame to move the seedling box, seedling discharge assembly, rotating shaft, seedling blowing mechanism, and washing mechanism to the mudflat. Initially, the seedling discharge pipe and guide pipe of each seedling discharge assembly are only connected to a pair of seedling separation chambers directly opposite each other inside the shell. The seedlings are poured into the seedling box, and under their own gravity, they fall through the seedling discharge pipes into the seedling separation chambers connected to the corresponding seedling discharge pipes inside the shell. Then, the controller controls the motor to drive the rotating shaft to rotate intermittently, with each rotation being 1 / 2n revolutions. During the intermittent rotation of the rotating shaft, each seedling separation plate rotates intermittently, and with each rotation of the rotating shaft, the seedling discharge pipe and guide pipe of each seedling discharge assembly are connected to the next pair of seedling separation chambers directly opposite each other inside the shell. Under their own gravity, the seedlings fall through the seedling discharge pipes into the seedling separation chamber connected to the seedling discharge pipe in the next pair of seedling separation chambers.

[0019] When the rotary shaft rotates n times, the moving trolley drive frame moves the seedling box, seedling discharge assembly, rotary shaft, seedling blowing mechanism, and cleaning mechanism forward. As the rotary shaft continues to rotate intermittently, when each seedling guide tube connects to a seedling separation chamber containing seedlings in its corresponding shell, the seedlings in the separation chamber fall into the seedling blowing tube under their own gravity. The photoelectric sensor detects the seedlings falling, the controller controls the fan to work, and controls the solenoid valve to open. The airflow is discharged from the fan's exhaust port, passes through the solenoid valve into the air guide tube, and then enters the corresponding seedling blowing tube from each exhaust port, blowing the seedlings in each seedling blowing tube out and scattering them onto the mudflats.

[0020] The present invention has the following beneficial effects:

[0021] This invention can replace manual labor in shellfish seeding, and the breakage rate of shellfish seedlings is low during seeding. Specifically, the invention uses a cleaning mechanism to wash and clean all parts that come into contact with the shellfish seedlings, and applies a water film to the surface of these parts, reducing friction between the shellfish seedlings and these parts, thereby reducing the breakage rate. Furthermore, the invention uses a controller to control a motor to drive a rotating shaft, causing each seedling separating plate to rotate intermittently, transporting the shellfish seedlings between adjacent separating plates within each shell to the seedling blowing pipe, thus achieving the seedling transport function. Further, when a photoelectric sensor detects shellfish seedlings in the seedling blowing pipe, the controller activates a fan, and the airflow blows the shellfish seedlings out of each blowing pipe. The discharge pipe, shell, guide pipe, and blowing pipe are arranged in multiple aligned sets, allowing the airflow to evenly distribute the shellfish seedlings from each blowing pipe onto the mudflats in one go. This replaces manual labor in shellfish seeding, reduces labor costs, lowers seeding costs, and improves seeding efficiency. At the same time, the invention has a simple structure and low manufacturing cost. Attached Figure Description

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides an air-blowing shellfish seeding device, comprising a seedling box 1, a seedling discharge mechanism, a seedling blowing mechanism, a cleaning mechanism, and a frame 25.

[0031] The seedling box 1 is fixed on the frame 25. The seedling feeding mechanism is located directly below the seedling box 1 and includes a seedling feeding assembly, a rotating shaft 7, and a seedling separating plate assembly. The seedling feeding assembly has multiple components arranged equidistantly in the horizontal direction, including a seedling feeding pipe 4, a shell 5, and a seedling guide pipe. The vertically arranged seedling feeding pipe 4 is fixed at both ends to the seedling box 1 and the shell 5, and the inner cavity of the shell 5 is connected to the inner cavity of the seedling box 1 through the seedling feeding pipe 4. The upper end of the seedling guide pipe is fixed to the shell 5. The horizontally arranged rotating shaft 7 passes through a pair of holes opened on each shell 5 and forms a rotating pair with the frame 25, and is driven by a motor 8. A seedling separating plate assembly is provided on the rotating shaft 7 at the position of each shell 5 inner cavity. The seedling separating plate assembly consists of 2n seedling separating plates 6 arranged equidistantly in the circumferential direction, where n≥2. The seedling separating plates 6 are fixed on the rotating shaft 7 and arranged in the radial direction. Each seedling separating plate assembly divides the corresponding shell inner cavity into 2n seedling separating chambers. Among them, the diameters of the seedling discharge tube 4 and the seedling guide tube are both smaller than the distance between the ends of the two adjacent seedling separation plates 6 that are far from the rotating shaft 7.

[0032] The seedling blowing mechanism includes a blower 9, a solenoid valve 12, an air guide pipe 14, and a seedling blowing pipe 15. The blower 9 is fixed on the seedling box 1, and the exhaust port 1 of the blower 9 is connected to the air inlet 1 of the solenoid valve 12 fixed on the frame 25 through the exhaust pipe 13. The exhaust port 2 of the solenoid valve 12 is connected to the air inlet 2 of the air guide pipe 14. The air guide pipe 14 is horizontally fixed on the frame 25, and the end of the air guide pipe 14 away from the solenoid valve 12 is closed. Multiple exhaust ports 3 are equidistantly arranged along the axial direction on the air guide pipe 14. Each exhaust port 3 is fixed with a downwardly inclined seedling blowing pipe 15. Each seedling blowing pipe 15 is connected to the air guide pipe 14. The lower end of each seedling guide pipe is fixed to the middle of a seedling blowing pipe 15. The inner cavity of each shell 5 is connected to each seedling blowing pipe 15 through each seedling guide pipe. A photoelectric sensor 11 is provided in the middle of each seedling blowing pipe 15. The photoelectric sensor 11 is used to detect whether the seedlings are transported into the seedling blowing pipe 15.

[0033] The cleaning mechanism includes a water tank 16, a water pipe 17, a nozzle 18, and a valve 19. The water tank 16 is fixed on the frame 25, and the outlet of the water tank 16 is connected to the inlet of the water pipe 17 through the valve 19. The shape of the water pipe 17 is consistent with the shape of the opening at the top of the seedling box 1, and the water pipe 17 is fixed on the opening. Multiple nozzles 18 are fixed on the water pipe 17 and are equidistantly arranged along the circumference of the opening. Each nozzle 18 is connected to the water pipe 17.

[0034] As a preferred embodiment, such as Figure 4 As shown, the lower end of the seedling box 1 has multiple seedling discharge holes 2 arranged at equal intervals. Two seedling separation baffles 3 arranged in a V-shape are fixed on both sides of each seedling discharge hole 2, and the two seedling separation baffles 3 between each two adjacent seedling discharge holes 2 are combined into an arched baffle; each seedling discharge pipe 4 is fixed to one seedling discharge hole 2.

[0035] More preferably, both the seedling divider 3 and the seedling divider 6 are made of flexible materials such as rubber.

[0036] In a preferred embodiment, the housing of the motor 8 is fixed on the frame 25, and the output shaft of the motor 8 is connected to the rotary shaft 7 via a coupling 24.

[0037] In a preferred embodiment, the rotary shaft 7 is supported on the frame 25 by a bearing housing 23.

[0038] As a preferred embodiment, such as Figure 5 , Figure 6 and Figure 7 As shown, a brush is fixed to one end of the seedling separating plate 6 away from the rotating shaft 7.

[0039] In a preferred embodiment, a pipe vibrator 10 is provided on the seedling guide tube to prevent the seedlings from adhering to the seedling guide tube.

[0040] More preferably, a touch screen 22 is provided on the frame 25, through which the amplitude of each pipe vibrator 10, the flow rate of the fan 9 and the speed of the motor 8 can be set.

[0041] The signal output terminals of each photoelectric sensor 11 are connected to the controller 21 located on the frame 25. The fan 9 is connected to the controller 21 through the frequency converter 20. The motor 8, solenoid valve 12, valve 19, frequency converter 20 and each pipe vibrator 10 are all controlled by the controller 21. The controller 21 communicates with the touch screen 22.

[0042] The present invention discloses a seeding method for a pneumatic shellfish seeding device, the specific details of which are as follows:

[0043] Water is filled into the water storage tank 16 (and pressurized after sealing with a lid). The controller 21 controls the valve 19 to open and controls the motor 8 to drive the rotary shaft 7 to rotate one revolution. The water flows into the water pipe 17, is sprayed onto the inner wall of the seedling box 1 by each nozzle 18, and then enters each housing 5 through each seedling discharge pipe 4, then enters each seedling guide pipe through each seedling blowing pipe 15, and finally flows out from the outlet of each seedling blowing pipe 15. The water flow washes the seedling box 1, each seedling discharge pipe 4, each housing 5, each seedling guide pipe, and each seedling blowing pipe. The water film removes impurities from seedlings 15 and each seedling plate 6, and coats the inner walls of seedling boxes 1, each seedling discharge pipe 4, each shell 5, each seedling guide pipe and each seedling blower 15, as well as the surface of each seedling plate 6, reducing friction between the seedlings and the inner walls of seedling boxes 1, each seedling discharge pipe 4, each shell 5, each seedling guide pipe and each seedling blower 15, as well as the surface of each seedling plate 6, thus reducing the damage rate of the seedlings. After the rinsing work is completed, the controller 21 controls the valve 19 to close and controls the motor 8 to stop working.

[0044] The frame 25 is mounted on a mobile trolley, which drives the frame 25 to move the seedling box 1, seedling discharge assembly, rotating shaft 7, seedling blowing mechanism, and cleaning mechanism to the mudflat. In the initial state, the seedling discharge pipe 4 and seedling guide pipe of each seedling discharge assembly are only connected to a pair of seedling separation chambers directly opposite each other in the shell 5. The seedlings are poured into the seedling box 1, and the seedlings in the seedling box 1 fall through the seedling discharge pipe 4 into the seedling separation chambers in the shell 5 connected to the corresponding seedling discharge pipe 4 under their own gravity. Then, the controller 21 controls the motor 8 to drive the rotating shaft 7 to rotate intermittently, and each rotation is 1 / 2n revolutions. During the intermittent rotation of the rotating shaft 7, the seedling separation plates 6 rotate intermittently. Each time the rotating shaft 7 rotates, the seedling discharge pipe 4 and seedling guide pipe of each seedling discharge assembly are connected to the next pair of seedling separation chambers directly opposite each other in the shell 5. The seedlings in the seedling box 1 fall through the seedling discharge pipe 4 into the seedling separation chamber connected to the seedling discharge pipe 4 in the next pair of seedling separation chambers under their own gravity.

[0045] When the rotary shaft 7 rotates n times, the moving trolley drive frame 25 drives the seedling box 1, seedling discharge assembly, rotary shaft 7, seedling blowing mechanism and cleaning mechanism forward. As the rotary shaft 7 continues to rotate intermittently, when each seedling guide tube is connected to a seedling separation chamber containing shellfish seedlings in the corresponding shell 5, the shellfish seedlings in the separation chamber fall into the seedling blowing tube 15 under their own gravity. The photoelectric sensor 11 detects the shellfish seedlings falling, and the controller controls the fan 9 to work (working for more than 3 seconds to avoid the fan 9 frequently opening and closing due to the slight difference in the time when the corresponding photoelectric sensor 11 detects the shellfish seedlings falling in different seedling blowing tubes 15). The controller also controls the solenoid valve 12 to open, and the airflow is discharged from the exhaust port of the fan 9, enters the air guide tube 14 through the solenoid valve 12, and then enters the corresponding seedling blowing tube 15 from each exhaust port, blowing out the shellfish seedlings in each seedling blowing tube 15. The shellfish seedlings are evenly scattered on the mudflats, thus realizing the shellfish seedling sowing work.
