Description

Technical Field

[0001] The utility model relates to the technical field of fish transportation, in particular to a two-way fish transportation channel of a tuna boat. Background Art

[0002] After catching tuna in the open sea with a purse seine, the tuna in the purse seine is salvaged onto the boat using a net bag. The tuna are then slaughtered and bled, and finally moved to a freezer for low-temperature freezing.

[0003] A Chinese patent disclosed a fish transportation channel for a tuna boat with a publication number of CN217456275U, and the application date is 2022.02.17. The patented technology puts the processed tuna into the opening, and then slides down along the fish inlet pipe. When the tuna needs to be transported to the freezing chamber in the stern direction, the first rotating shaft and the guide plate are driven by the driving mechanism to rotate clockwise, and the guide plate blocks the second channel. At this time, the tuna dropped from the fish inlet pipe slides along the guide plate into the first channel and slides to the corresponding conveyor belt in the stern direction. When the tuna needs to be transported to the freezing chamber in the bow direction, the first rotating shaft and the guide plate are driven to rotate clockwise, and the guide plate blocks the second channel. When the tuna is put into the tank, the first rotating shaft and the guide plate are driven by the driving mechanism to rotate counterclockwise, and the guide plate blocks the first channel. At this time, the tuna dropped from the fish inlet pipe slides along the guide plate into the second channel and slides toward the bow to the corresponding conveyor belt. The operation is simple, eliminating the trouble of manual handling, saving time and effort; however, after the tuna is poured into the opening, the number of tuna poured in at one time may cause the fish in the pipe to squeeze each other at the same time, which may cause the gun bone at the mouth of a tuna to pass through the sliding groove and get stuck in the first return spring, thereby affecting the switching between the first channel and the second channel. Therefore, those skilled in the art provide a two-way fish transportation channel for a tuna boat to solve the problems raised in the above background technology. Summary of the invention

[0004] The utility model aims to provide a two-way fish transportation channel for a tuna boat, which facilitates the switching of the transportation channel and avoids the influence of the device operation when the fish enters.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A two-way fish transportation channel for a tuna boat comprises a delivery pipe, wherein both sides of the bottom of the delivery pipe are fixedly connected with mirror-symmetrical transport channels, the transport channels are connected to the delivery pipe at the connection, and connecting plates are fixedly connected on opposite sides of the two transport channels, a channel switching mechanism is installed on the connecting plate, the channel switching mechanism comprises a rotatable rotating rod, a V-shaped turning plate is fixedly connected to the rotating rod, extension grooves are opened on both sides of the turning plate, and an extendable or retractable extension plate is installed inside the extension groove.

[0007] As a further solution of the utility model: a group of support springs are fixedly connected to one side of the extension plate, and the other side of the support springs is fixedly connected to the inside of the extension groove; a group of guide blocks for adjusting the extension length of the extension plate are fixedly connected to one side of the transport channel.

[0008] As a further solution of the utility model: a guide groove is provided on one side of the guide block; a movable rod is rotatably connected to one side of the extension plate, and the movable rod is slidably connected to the guide groove.

[0009] As a further solution of the utility model: rollers are fixedly connected to both sides of the movable rod, and the rollers are rollingly connected to the guide grooves.

[0011] One side of the connection is fixed.

[0012] As a further solution of the utility model: the cross section of the guide groove is matched with the outer side surface of the extension plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The bidirectional fish transportation channel of the tuna boat starts the motor through an external power supply, and the output end of the motor drives the rotating rod to rotate. When the output end of the motor rotates clockwise, it drives the turning plate to rotate in the same direction, so that the movable rods on both sides slide along the inside of the guide groove, driving the left extension plate to reveal the extension groove, and the right extension plate is gradually recovered in the extension groove, until the left movable rod is located at the top of the guide groove, and the extension plate is located at the outermost end of the extension groove to close the left transportation channel, and when the right movable rod is located at the bottom of the guide groove, this side of the turning plate fits with the connecting plate, and the extension plate shrinks inside the extension groove, and the transportation channel on this side is opened. Similarly, when the output end of the motor rotates counterclockwise, the right transportation channel will be closed and the left transportation channel will be opened at the same time. The coordination of the above structure facilitates the switching of the transportation channels while avoiding affecting the operation of the device when fish enters.

[0015] In addition, when the turning plate of the two-way fish conveying channel of the tuna boat is turned over, it will drive the movable rod to slide inside the guide groove, drive the extension plate to slide forward or backward, so as to achieve the effect of adjusting the length of the exposed part of the extension plate.

DETAILED DESCRIPTION

[0021] like Figure 1 , 2 As shown, a two-way fish transportation channel of a tuna boat includes a delivery pipe 10, and mirror-symmetrical transportation channels 11 are obliquely fixedly connected to the left and right sides of the bottom of the delivery pipe 10, the transportation channels 11 are connected to the delivery pipe 10 at the connection, and connecting plates 12 are fixedly connected to the opposite sides of the two transportation channels 11.

[0022] Conveyor belts for conveying tuna to the outside are installed inside the two conveying channels 11. The two conveying channels convey different places. For example, tuna are divided according to their size or weight, and then different tunas are conveyed to different treatment or processing positions according to conveying channels on different sides. Since tuna are all put into one delivery pipe 10, in order to prevent tuna from being put into the wrong delivery channel 11, a channel switching mechanism 20 is proposed.

[0023] refer to Figure 2 , 3, a channel switching mechanism 20 is installed on the connecting plate 12, and the channel switching mechanism 20 includes a rotatable rotating rod 209, the rotating rod 209 passes through the surface of the connection of the two transport channels 11, and a turning plate 201 is fixedly connected to the rotating rod 209, and the turning plate 201 is in a "V" shape, and the angle between the two ends of the turning plate 201 is 145 degrees. When in use, the turning plate 201 is driven by the rotating rotating rod 209 to rotate clockwise or counterclockwise. When the rotating rod 209 rotates clockwise, it drives the turning plate 201 to rotate in the same direction, so that the left side of the turning plate 201 abuts against the top surface of the left transport channel 11, and the right side of the turning plate 201 fits with the surface of the connecting plate 12, so as to achieve the effect of closing the left transport channel 11 and opening the right transport channel 11 at the same time. Similarly, when the rotating rod 209 rotates counterclockwise, the right side of the turning plate 201 abuts against the top surface of the right transport channel 11, and the left side of the turning plate 201 fits against the surface of the connecting plate 12, thereby achieving the effect of closing the left transport channel 11 and opening the right transport channel 11 at the same time.

[0024] When the above structure is in operation, the lengths of both sides of the turning plate 201 are greater than half of the connecting plate 12. Therefore, when one side of the turning plate 201 is in contact with the surface of the connecting plate 12, one side of the turning plate 201 will extend beyond the connecting plate 12, so that a part of the transport channel 11 on the open side is covered, which may cause the transport channel 11 on the open side to be blocked after a large amount of tuna is delivered. Therefore, some modifications are made to the turning plate 201.

[0025] refer to Figure 2 , 3 4. The length of one side of the turning plate 201 is half of the length of the connecting plate 12, so that no matter which side of the turning plate 201 is in contact with the surface of the connecting plate 12, the space of the transport channel 11 will not be occupied. Meanwhile, the two sides of the turning plate 201 are provided with extension grooves 202, and a group of support springs 203 are fixedly connected to the inner side of the extension groove 202 close to the rotating rod 209, and the outer sides of the two groups of support springs 203 are fixedly connected to the extension plates 204. When the support springs 203 are not pressed, the length of the one-side turning plate 201 plus the extension plate 204 is consistent with the original length of the one-side turning plate 201, so as to close the transport channel 11.

[0026] refer to Figure 2 , 34. A pair of guide blocks 30 are fixedly connected to the opposite ends of the two transport channels 11. The guide blocks 30 are respectively fixedly connected to the front and rear side surfaces of the interior of the transport channel 11. A guide groove 31 is provided on the opposite sides of the pair of guide blocks 30 in the same transport channel 11. The guide groove 31 is designed to be an arc with a gradually increasing arc curvature from bottom to top. A movable rod 205 is rotatably connected to the side of the extension plate 204 away from the rotating rod 209. The movable rod 205 is movably connected to the guide groove 31. Therefore, when the turning plate 201 is turned over, the movable rod 205 will be driven to slide inside the guide groove 31, driving the extension plate 204 to slide forward or backward, so as to adjust the length of the exposed part of the extension plate 204. When the movable rod 205 on one side is located at the bottom of the guide groove 31, the side of the turning plate 201 is in contact with the connecting plate 12, the extension plate 204 is retracted inside the extension groove 202, and the transport channel 11 on this side is opened, and at the same time, when the movable rod 205 on the other side is located at the top of the guide groove 31, the extension plate 204 is located at the outermost end of the extension groove 202 to close the transport channel 11 on the other side. Thus, the effect of not occupying the channel space when switching the transport channel 11 is achieved.

[0027] Preferably, the cross section of the guide groove 31 is matched with the outer surface of the extension plate 204, so as to achieve a guiding effect when the extension plate 204 moves.

[0028] Preferably, reference Figure 3 The front and rear sides of the movable rod 205 are respectively fixedly connected with rollers 206 , and the rollers 206 are rollingly connected to the inside of the guide groove 31 , which can make it easier for the movable rod 205 to move inside the guide groove 31 .

[0029] refer to Figure 1 A support plate 207 is fixedly connected to the front of the connecting plate 12 , a motor 208 is fixedly connected to the top of the support plate 207 , and an output end of the motor 208 is fixedly connected to the front side of the rotating rod 209 .

[0030] The working principle of the utility model is as follows: when in use, the motor 208 is started by an external power supply, and the output end of the motor 208 drives the rotating rod 209 to rotate. When the output end of the motor 208 rotates clockwise, the turning plate 201 is driven to rotate in the same direction, so that the movable rods 205 on both sides slide along the inside of the guide groove 31, driving the left extension plate 204 to reveal the extension groove 202, and the right extension plate 204 is gradually recovered in the extension groove 202, until the left movable rod 205 is located at the top of the guide groove 31, the extension plate 204 is located at the outermost end of the extension groove 202 to close the left transport channel 11, and when the right movable rod 205 is located at the bottom of the guide groove 31, the side of the turning plate 201 is fitted with the connecting plate 12, the extension plate 204 shrinks inside the extension groove 202, and the transport channel 11 on this side is opened. Similarly, when the output end of the motor 208 rotates counterclockwise, the right transport channel 11 is closed, and the left transport channel 11 is opened.
