Description

Technical Field

[0001] This utility model relates to the field of material screening equipment manufacturing technology, and in particular to a screening machine for shellfish materials. Background Technology

[0002] In the cultivation of shellfish such as abalone, screening abalone seedlings or matured abalone by size is an important task. Different cultivation plans or sales plans are developed based on the different sizes of abalone seedlings and matured abalone.

[0003] Traditional manual screening methods are inefficient and cannot meet the needs of large-scale aquaculture. To improve screening efficiency, abalone screening machines have appeared on the market. For example, a Chinese utility model patent with patent number Z202123180013.6, entitled "Screening Machine," was published on May 31, 2022. This machine includes a frame with support rollers rotatably connected at both ends. An inclined screen cylinder is rolled on the support rollers. The screen holes at both ends of the screen cylinder have different diameters. Rings are connected to both ends of the screen cylinder, one of which is connected to a driven gear. The driven gear meshes with a driving gear, which is connected to the output shaft of a drive motor. The drive motor is connected to the frame. This utility model, through the coordinated use of the driving gear, driven gear, and screen cylinder, allows smaller abalone to pass through the screen holes in the front half of the screen cylinder into the front discharge hopper below the frame, while larger abalone pass through the screen holes in the rear half into the rear discharge hopper below the frame. The structure is relatively simple and the operation is convenient. However, this screening machine can only screen a limited number of grades, and because abalone tends to clump together and is difficult to break up, the accuracy of the screening grades needs to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a screening machine for shellfish materials, which can realize automatic material distribution, feeding and screening, effectively improve the level of automation, reduce the labor intensity of operators, and can screen a wide range of grades with high accuracy.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a screening machine for shellfish materials, including a first support frame, a vibrating screen, and a feeding trough. The vibrating screen includes a feeding trough, the lower part of which is connected to the first support frame by multiple first springs. A vibrating motor is installed at the lower part of the feeding trough. Multiple screening plates are arranged in the feeding trough from top to bottom. Each screening plate has multiple screening holes. The cross-sectional area of ​​the screening holes on the upper screening plate is larger than that on the lower screening plate. The output end of the feeding trough has multiple discharge ports, and each screening plate is connected to one discharge port.

[0006] The discharge end of the feeding trough is located above the feed end of the feeding trough; the lower front side of the feeding trough is connected to the second support frame by the second spring, and the second support frame is fixed to the feeding trough; the lower rear side of the feeding trough is connected to the third support frame by the third spring, and the third support frame is fixed to the feeding trough or directly supported on the ground.

[0007] In a further improvement, a first nut is fixedly connected to the third spring on the third support frame, and a vertically arranged adjusting screw is screwed onto the first nut. A supporting shoulder is provided on the upper part of the adjusting screw, and the lower part of the third spring is sleeved on the upper part of the adjusting screw and the lower end of the third spring is supported on the shoulder.

[0008] Alternatively, a vertically arranged adjusting screw is fixed to the third spring on the third support frame. An adjusting nut is screwed onto the adjusting screw and a washer is fitted on it. The washer abuts against the upper end of the adjusting nut. The lower part of the third spring is fitted onto the upper part of the adjusting screw and the lower end of the third spring is supported on the washer.

[0009] Alternatively, a first nut may be fixed to the third spring on the third support frame. A vertically arranged adjusting screw may be screwed onto the first nut. An adjusting nut may be screwed onto the adjusting screw and a washer may be fitted on it. The washer may be pressed against the upper end of the adjusting nut. The lower part of the third spring may be fitted onto the upper part of an adjusting screw and the lower end of the third spring may be supported on the washer.

[0010] This allows for adjustment of the inclination of the feeding chute, which in turn allows for adjustment of the material's dispersion and falling speed, thus enabling adjustment of the dispersion and feeding speed to match the screening speed of the vibrating screen.

[0011] In a further improvement, when the third support frame is fixed to the material trough, it is integrated with the second support frame via a connecting rod. This enhances the support strength and better transmits the vibration force of the vibrating screen.

[0012] When the third support frame is directly supported on the ground, it is connected to the first support frame via a connecting rod. This prevents the third support frame from shifting and improves the reliability of the support.

[0013] Preferably, the cross-section of the material trough is U-shaped, and a first U-shaped frame is fixedly connected to the bottom surface of the material trough. The opening end of the first U-shaped frame is located near the discharge port. Screening plates are stacked on the first U-shaped frame, and two adjacent screening plates are separated by a second U-shaped frame. The opening end of the second U-shaped frame is located near the discharge port.

[0014] Multiple second nuts are fixed to the upper perimeter of the material trough, and each second nut is screwed with a vertically arranged clamping bolt. A pressure strip is installed near the edge of the uppermost screening plate, excluding the outlet. The lower end of the clamping bolt abuts against the pressure strip, and the pressure strip clamps the multi-layer screening plate and the second U-shaped frame. This effectively prevents collision noise from the screening plate, the second U-shaped frame, the first U-shaped frame, and the material trough during vibration, thus reducing the operating noise of the vibrating screen.

[0015] Preferably, each layer of the screening plate also includes a support frame fixedly connected to the lower end face of the screening plate. The support frame includes a frame fixed to the peripheral edge of the lower end face of the screening plate and multiple round tubes connecting the frame. The multiple round tubes support the lower end face of the screening plate to facilitate material discharge.

[0016] Preferably, the material trough is equipped with three layers of screening plates, and the output end of the material trough has three discharge ports. Each layer of screening plates is connected to one discharge port at the output end of the material trough. The side of the material trough also has a discharge port, which is connected to the inner bottom surface of the material trough. In this way, the screening machine can screen materials of four grades, providing a wide range of screening levels.

[0017] Furthermore, a material receiving platform is provided at the rear of the trough, which can receive materials jumping backward and prevent them from falling out of the vibrating screen; a waterproof cover is provided at the bottom of the trough, and the vibrating motor is located inside the waterproof cover. This can better protect the vibrating motor.

[0018] As a further improvement, multiple support wheel assemblies are installed on the front and rear sides of the lower part of the first support frame. The support wheel assemblies can adjust the support height relative to the first support frame. This makes it easy to adjust the tilt of the entire vibrating screen and adjust the discharge speed.

[0019] A U-shaped bracket is fixed to the rear of the feeding trough. The U-shaped bracket allows the flexible water pipe to pass through and holds the flexible water pipe in place. Flushing water through the flexible water pipe can also break up piles of shellfish material, making it easier to distribute the material during feeding.

[0020] The shellfish material is preferably abalone.

[0021] In a further improvement, a first water pipe is installed on the feed trough, and the first water pipe has multiple first water outlets. The first water outlets spray water into the feed trough to flush and drive the shellfish material.

[0022] A second water pipe is installed above the feeding trough, and the second water pipe has multiple second water outlets. The second water outlets spray water into the feeding trough to flush and drive the shellfish material, thereby dispersing and screening the material.

[0023] Furthermore, multiple first water pipes are arranged at intervals along the direction perpendicular to the output direction of the feed trough. These multiple first water pipes are connected to form the same first water circuit. The water outlet directions of the first water outlets of different first water pipes can be set to be the same or different.

[0024] Multiple second water pipes are arranged at intervals along the discharge direction perpendicular to the material discharge trough. Multiple second water pipes are connected to form the same second water circuit. The discharge directions of the second water outlets of different second water pipes can be set to be the same or different.

[0025] The first waterway and the second waterway are connected by a flexible hose and connected to the same inlet pipe, or the first waterway and the second waterway are each connected to different external inlet pipes.

[0026] In this invention, the discharge end of the feeding trough is located above the inlet end; the lower front side of the feeding trough is connected to a second support frame via a second spring, and the second support frame is fixedly connected to the feeding trough; the lower rear side of the feeding trough is connected to a third support frame via a third spring, and the third support frame is fixedly connected to the feeding trough or directly supported on the ground. In this way, the feeding trough can automatically disperse and feed materials following the vibration of the vibrating screen.

[0027] Secondly, the material trough is equipped with multiple screening plates arranged at intervals from top to bottom. Each screening plate has multiple screening holes, and the cross-sectional area of ​​the screening holes on the upper screening plate is larger than that on the lower screening plate. The trough also has multiple discharge ports, with each screening plate connected to one discharge port. This allows for a wider range of screening grades with greater accuracy. The entire device can automatically distribute, discharge, and screen materials, effectively improving automation and reducing the workload of operators. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] Example 1 Figures 1 to 8 As shown, a shellfish material screening machine includes a first support frame 1, a vibrating screen 2, and a feeding trough 3. The vibrating screen 2 includes a feeding trough 21. The lower part of the feeding trough 21 is connected to the first support frame 1 by four first springs 4. Specifically, the lower part of the feeding trough 21 is provided with four first lower protrusions 21a, each first lower protrusion 21a being fitted onto the upper part of a first spring 4. The first support frame 1 is provided with four first upper protrusions 11, each first upper protrusion 11 being fitted onto the lower part of a first spring 4. This also facilitates the removal of the feeding trough 21.

[0039] Two vibrating motors 5 are installed at the bottom of the material trough 21. Three screening plates 6 are arranged at intervals from top to bottom inside the material trough 21. Each screening plate 6 has multiple screening holes 61. The cross-sectional area of ​​the screening holes 61 on the upper screening plate 6 of two adjacent screening plates 6 is larger than that on the lower screening plate 6. The output end of the material trough 21 has three discharge ports 22, and each screening plate 6 is connected to one discharge port 22. There is also a discharge port 22 on the side of the material trough 21, and the bottom surface of the material trough 21 is connected to the discharge port 22 on the side of the material trough 21.

[0040] The discharge end of the feeding trough 3 is located above the feeding end of the feeding trough 21; the lower front side of the feeding trough 3 is connected to the second support frame 7 by two second springs 41; specifically, the lower part of the feeding trough 3 is provided with two second lower protrusions 3a, each second lower protrusion 3a is sleeved on the upper part of a second spring 41, and the second support frame 7 is provided with two second upper protrusions 7a, each second upper protrusion 7a is sleeved on the lower part of a second spring 41;

[0041] The second support frame 7 is fixedly connected to the material trough 21. The second support frame 7 can be fixedly connected to the material trough 21 by bolts or welding.

[0042] The lower rear side of the feeding trough 3 is connected to the third support frame 71 by two third springs 42. The lower part of the feeding trough 3 is provided with two third lower protrusions 3b, each of which is fitted on the upper part of a third spring 42. The third support frame 71 is fixed to the feeding trough 21. The third support frame 71 can be fixed to the feeding trough 21 by bolts or welding. The third support frame 71 can also be connected to the second support frame 7 by a connecting rod 70 to enhance the support strength and transmit the vibration force of the vibrating screen 2.

[0043] Two first nuts 72 are fixed to two third springs 42 on the third support frame 71. Each first nut 72 is screwed with a vertically arranged adjusting screw 73. The upper part of the adjusting screw 73 is provided with a support shoulder 731. The lower part of each third spring 42 is sleeved on the upper part of an adjusting screw 73, and the lower end of the third spring 42 is supported on the shoulder 731. In this way, the inclination of the feeding trough 3 can be adjusted by rotating the adjusting screw 73, which is conducive to adjusting the dispersion and falling speed of the material, that is, adjusting the dispersion and feeding speed, which is convenient to adapt to the screening speed of the vibrating screen 2. Secondly, the entire feeding trough 3 is also easy to disassemble.

[0044] As a variation, another adjustment structure can be: an adjusting screw 73 is vertically fixed to the third support frame 71, an adjusting nut is screwed onto the adjusting screw 73 and a washer is fitted on it, the washer rests against the adjusting nut, and the lower part of each third spring 42 is fitted onto the upper part of an adjusting screw 73, with the lower end of the third spring 42 supported on the washer. In this way, the inclination of the feed chute 3 can also be adjusted by rotating the adjusting screw 73.

[0045] As another variation, another adjustment structure can be: two first nuts 72 are fixed to the two third springs 42 on the third support frame 71. Each first nut 72 is screwed with a vertically arranged adjusting screw 73. An adjusting nut is screwed onto the adjusting screw 73 and a washer is fitted on it. The washer rests against the adjusting nut. The lower part of each third spring 42 is fitted onto the upper part of an adjusting screw 73, and the lower end of the third spring 42 is supported on the washer. In this way, the inclination of the feeding trough 3 can be coarsely adjusted by rotating the adjusting screw 73, and the inclination of the feeding trough 3 can be finely adjusted by rotating the adjusting nut.

[0046] Each layer of the screening plate 6 also includes a support frame 62 fixedly connected to the lower end face of the screening plate 6. The support frame 62 includes a square frame 621 fixedly connected to the peripheral edge of the lower end face of the screening plate 6 and multiple round tubes 622 connecting the square frame 621. The multiple round tubes 622 support the lower end face of the screening plate 6. By using round tubes 622 to support the lower end face of the screening plate 6, not only can the rigidity of the screening plate 6 be enhanced, but it is also convenient for shellfish materials to fall through the screening holes 61.

[0047] The cross-section of the material trough 21 is U-shaped, and a first U-shaped frame 23 is fixedly connected to the bottom surface of the material trough 21. The structural diagram of the first U-shaped frame 23 is shown below. Figure 8 The first U-shaped frame 23 is positioned with its open end close to the discharge port 22. Screening plates 6 are stacked on the first U-shaped frame 23. Specifically, the first U-shaped frame 23 abuts against the support frame 62. Adjacent screening plates 6 are separated by a second U-shaped frame 24. The open end of the second U-shaped frame 24 is positioned close to the discharge port 22. The structure of the second U-shaped frame 24 is the same as that of the first U-shaped frame 23. Figure 5As further shown, the upper surface of the second U-shaped frame 24 abuts against the square frame 621, and the upper surface of the second U-shaped frame 24 abuts against the first layer of screening plate 6.

[0048] Multiple second nuts 8 are fixedly connected to the upper periphery of the material trough 21. Each second nut 8 is screwed with a vertically arranged clamping bolt 81. A pressure strip 82 is provided near the edge of the uppermost screening plate 6, except for the connection to the discharge port 22. The lower end of the clamping bolt 81 abuts against the pressure strip 82 and clamps the multi-layer screening plate 6 and the second U-shaped frame 24 through the pressure strip 82. This can prevent the screening plate 6, the second U-shaped frame 24, the first U-shaped frame 23 and the material trough 21 from generating collision noise when vibrating.

[0049] Two support wheel assemblies 9 are installed on the front and rear sides of the lower part of the first support frame 1. The support wheel assembly 9 can adjust the support height relative to the first support frame 1. This makes it easier to adjust the inclination of the vibrating screen 2.

[0050] A U-shaped bracket 31 is also fixedly connected to the rear of the feeding trough 3. The U-shaped bracket 31 allows the flexible water pipe to pass through and holds the flexible water pipe in place. The water flow through the flexible water pipe can also disperse the piled shellfish material, which is conducive to the dispersion of the material during feeding.

[0051] The preferred shellfish material selected is abalone.

[0052] The feed trough 21 is equipped with a first water pipe 25, and the lower part of the first water pipe 25 is provided with multiple first water outlets. The first water outlets spray water into the feed trough 21 to flush and drive the shellfish material. Multiple first water pipes 25 are arranged at intervals along the direction perpendicular to the output direction of the feed trough 21. Multiple first water pipes 25 are connected to form the same first water circuit 250. The water outlet directions of the first water outlets of different first water pipes 25 can be set to be the same or different.

[0053] A second water pipe 32 is mounted on the feed trough 3. The second water pipe 32 has multiple second water outlets. The second water outlets spray water into the feed trough 3 to flush and drive the shellfish material.

[0054] Multiple second water pipes 32 are arranged at intervals along the discharge direction perpendicular to the discharge trough 3. Multiple second water pipes 32 are connected to form the same second water circuit 320. The discharge direction of the second water outlet of different second water pipes 32 can be set to be the same or different.

[0055] The first water passage 250 and the second water passage 320 are connected by a flexible hose 26 and are connected to the same inlet pipe. The first water passage 250 and the second water passage 320 can also be connected to different external inlet pipes.

[0056] The material trough 21 is equipped with a material support platform 27 at its rear top, which can receive materials jumping backward and prevent them from falling out of the vibrating screen 2; the material trough 21 is equipped with a waterproof cover 28 at its lower part, and the vibrating motor 5 is located inside the waterproof cover 28. This can better protect the vibrating motor 5.

[0057] In this embodiment, the support wheel assembly 9 is adjusted so that the material trough 21 and the discharge trough 3 are inclined to the horizontal plane, with the inlet end of the material trough 21 higher than the outlet end, and the rear side of the discharge trough 3 higher than the front outlet end. When screening shellfish such as abalone, the pile of abalone is poured directly into the discharge trough 3, the vibration motor 5 is started, the inlet water valve is opened, the vibrating screen 2 vibrates as a whole, and drives the discharge trough 3 to vibrate. The second outlets of multiple second water pipes 32 spray water into the discharge trough 3 to flush and drive the abalone. Through vibration and water flushing, the pile of abalone is dispersed and gradually falls onto the uppermost screening plate 6 of the vibrating screen 2. With the flushing of the first water pipe 25 and the vibration of the material trough 21, the abalone moves forward along the uppermost screening plate 6. Abalone that cannot pass through the screening holes 61 on the uppermost screening plate 6 are discharged from the uppermost layer. The abalone are discharged from the outlet 22. Abalone that pass through the screening holes 61 on the uppermost screening plate 6 fall into the second screening plate 6 and move forward along it. Abalone that cannot pass through the screening holes 61 on the second screening plate 6 are discharged from the outlet 22 on the second layer. Abalone that pass through the screening holes 61 on the second screening plate 6 fall into the third screening plate 6 and move forward along it. Abalone that cannot pass through the screening holes 61 on the third screening plate 6 are discharged from the outlet 22 on the third layer. Abalone that pass through the screening holes 61 on the third screening plate 6 fall into the bottom surface of the material trough 21 and move towards the output end along the bottom surface of the material trough 21. Finally, these abalone are discharged from the bottommost outlet 22, which is an outlet 22 on the side of the material trough 21. This achieves automatic dispersion and screening of abalone, dividing them into four grades with multiple and relatively accurate classifications.

[0058] In this embodiment, when it is necessary to replace the screening plate 6 or to thoroughly clean the screening plate 6, all clamping bolts 81 can be loosened, and the screening plate 6 can be pulled out from the rear side of the material trough 21, making replacement and cleaning very convenient.

[0059] Example 2 Figure 9 As shown, a shellfish material screening machine differs from Embodiment 1 in that the third support frame 71a is not connected to the material trough 21, but is directly supported on the ground. The structural shape of the third support frame 71a differs from that of the third support frame 71 in the first embodiment. The third support frame 71a is also connected to the first support frame 1 via two connecting rods 72a to prevent the third support frame 71a from shifting. The usage of this embodiment is basically the same as that of the first embodiment.

[0060] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
