Description

Technical Field

[0001] This invention relates to the field of seafood transportation technology, specifically a frozen seafood transportation device. Background Technology

[0002] Seafood refers to edible or usable animals and plants and their processed products in the ocean, covering categories such as fish, shellfish, shrimp, and algae. Common forms include live, chilled, and dried products.

However, the existing technology cannot make adaptive transport adjustments according to the different sizes of seafood, and it cannot remove the ice attached to the surface of the seafood. Therefore, it needs to be improved. Summary of the Invention

Detailed Implementation

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example 1, please refer to Figures 1-6 A seafood freezing conveying device includes a mounting base plate 1, a support and adjustment mechanism 2 at the bottom of the mounting base plate 1, a conveying box 3 on the mounting base plate 1, a discharge pipe 4 and a one-way exhaust valve 5 on the conveying box 3, a blower 6 on the conveying box 3, a conveying plate mechanism 7 fixedly connected to the conveying box 3, a conveying block mechanism 8 on the conveying box 3, a clapping mechanism 9 on the conveying box 3, a reciprocating lever mechanism 10 on the side of the conveying box 3, and a positioning linkage mechanism 11 between the conveying block mechanism 8 and the clapping mechanism 9. The support and adjustment mechanism 2 is used to adjust the height of the mounting base plate 1, the reciprocating lever mechanism 10 is used to drive the positioning linkage mechanism 11, the positioning linkage mechanism 11 is used to drive the conveying block mechanism 8 and the clapping mechanism 9 to reciprocate and rise and fall, and the conveying block mechanism 8 and the clapping mechanism 9 are used to clapping and convey seafood.

[0027] The support adjustment mechanism 2 includes a first displacement seat 201 and a second displacement seat 204 fixed to the bottom of the mounting base plate 1. Two of each type of displacement seat 201 and 204 are provided. The first displacement seat 201 is rotatably connected to a first support rod 202, which has a positioning block groove 203. The second displacement seat 204 is rotatably connected to a second support rod 205, which is rotatably connected to a deflection shaft 206. Two deflection shafts 206 are provided, symmetrically arranged on the second support rod 205. The deflection shafts 206 are rotatably connected to a sliding frame 207, which is slidably connected to the first support rod 202. A third displacement seat 208 is fixedly connected to the bottom of the mounting base plate 1. The third displacement seat 208 is rotatably connected to a hydraulic push rod 209. One end of the hydraulic push rod 209 away from the third displacement seat 208 is fixedly connected to a lifting block 210. The lifting block 210 is rotatably connected to a lifting shaft 211, which is rotatably connected to the sliding frame 207.

[0028] Specifically, activating the hydraulic push rod 209 can drive the lifting block 210 to rise or fall, which in turn drives the lifting shaft 211 to rise or fall, thereby causing the sliding frame 207 to move along the first support rod 202. This causes the first support rod 202 to rotate around the first positioner 201, and the second support rod 205 to rotate around the second positioner 204, in order to adjust the height of the mounting base plate 1.

[0029] The conveying plate mechanism 7 includes a fixed plate 701 fixed inside the conveying box 3. The fixed plate 701 has several equally spaced top block slots 702 and several first drainage holes 703. The conveying block mechanism 8 includes a sliding outer shell 801 slidably connected to the conveying box 3. A first motor 802 is installed inside the sliding outer shell 801. The output shaft of the first motor 802 is fixedly connected to a shift gear 803. The shift gear 803 meshes with two racks 804. The racks 804 are fixedly connected to a sliding inner plate 805. The sliding inner plate 805 is located inside the sliding outer shell 801 and is slidably connected to the sliding outer shell 801. The sliding inner plate 805 has a rack slot 806. Several equally spaced top blocks 807 are fixedly connected to the sliding outer shell 801. The end of each top block 807 away from the sliding outer shell 801 is inclined. The clapping mechanism 9 includes a lifting slide rod 901 that is slidably connected to the conveyor box 3. The lifting slide rod 901 passes through the conveyor box 3 and is fixedly connected to a lifting clapping plate 902. The lifting clapping plate 902 is inclined and has a plurality of second leakage holes 903.

[0030] Specifically, turning on the first motor 802 can drive the displacement gear 803 to rotate, thereby causing the displacement gear 803 to shift, which in turn causes the sliding inner plate 805 to shift. This causes the sliding inner plate 805 to shift relative to the sliding outer shell 801. When the side of the sliding outer shell 801 contacts the conveyor box 3, the sliding inner plate 805 will rise and fall as the sliding outer shell 801 rises and falls. At this time, under the action of air pressure, the blocked first leak hole 703 can be cleared.

[0031] Additionally, the lifting and lowering of the sliding outer shell 801 can drive the lifting and lowering of the top block 807. The top block 807 passes through the top block groove 702. The top block 807 pushes the seafood to shake off the ice on the surface of the seafood. At the same time, the lifting and lowering of the lifting slide 901 can drive the lifting plate 902 to lift and lower, thereby shaking off the ice attached to the surface of the seafood and causing the ice to fall off. In addition, since the surface of the top block 807 is inclined, and the lifting plate 902 is also inclined, the seafood can be shaken to the next top block 807, thus realizing the conveying of the seafood.

[0032] The reciprocating lever mechanism 10 includes a second motor 1001 fixed on the conveyor box 3. The output shaft of the second motor 1001 is fixedly connected to a rotating frame 1002. A rotating block groove 1003 is provided in the rotating frame 1002. A third motor 1004 is provided on the rotating frame 1002 in the rotating block groove 1003. The output shaft of the third motor 1004 is fixedly connected to an adjusting threaded rod 1005. The adjusting threaded rod 1005 is threadedly connected to a rotating block 1006. The rotating block 1006 is located in the rotating block groove 1003. The rotating block 1006 and the rotating frame 1002 are slidably connected. The rotating block 1006 is fixedly connected to a rotating shaft 1007. The positioning linkage mechanism 11 includes a fixed rod 1101, which is fixedly connected to a crossbar 1102. A transverse groove 1103 is provided on the crossbar 1102, and a rotating shaft 1007 is located within the transverse groove 1103. The fixed rod 1101 is fixedly connected to a fourth motor 1104. The output shaft of the fourth motor 1104 is fixedly connected to a first rotating rod 1105. The first rotating rod 1105 is rotatably connected to a first rotating shaft 1106. The first rotating shaft 1106 is rotatably connected to a second rotating rod 1107. The second rotating rod 1107 is rotatably connected to a second rotating shaft 1108. The second rotating shaft 1108 is rotatably connected to a first displacement block 1109. A first displacement block groove 1110 is provided on the fixed rod 1101, and the first displacement block 1109 is located within the first displacement block groove 1110. The first displacement block 1109 and the fixed rod 1101... The sliding connection includes a first displacement block 1109 fixedly connected to a telescopic rod 1118, a fifth motor 1111 mounted on the fixed rod 1101, an output shaft of the fifth motor 1111 fixedly connected to a third rotating rod 1112, a third rotating shaft 1113 rotatably connected to a third rotating shaft 1113, a fourth rotating rod 1114 rotatably connected to a fourth rotating shaft 1115, and a second displacement block 1116 rotatably connected to the fixed rod 1101. A second displacement block groove 1117 is provided on the fixed rod 1101, and the second displacement block 1116 is located within the second displacement block groove 1117. The second displacement block 1116 and the fixed rod 1101 are slidably connected. The fourth rotating shaft 1115 passes through the second displacement block 1116 and is rotatably connected to a lifting slide rod 901. The telescopic rod 1118 passes through the conveyor box 3, and a sealing slide plate 13 is provided on the conveyor box 3 at the position of the telescopic rod 1118. The telescopic rod 1118 and the sliding inner plate 805 are fixedly connected.

[0033] Specifically, when the second motor 1001 is turned on, the output shaft of the second motor 1001 rotates, which drives the rotating frame 1002 to rotate, thereby driving the rotating block 1006 to rotate, and then driving the rotating shaft 1007 to rotate. Since the rotating shaft 1007 is placed in the transverse groove 1103, the rotating shaft 1007 can drive the crossbar 1102 to move up and down repeatedly. When the third motor 1004 is turned on, it drives the adjusting threaded rod 1005 to rotate, thereby driving the rotating block 1006 to move along the rotating block groove 1003, thereby adjusting the position of the rotating shaft 1007, and thus adjusting the stroke of the crossbar 1102, that is, adjusting the stroke of the fixed rod 1101, in order to adjust the stroke of the conveying block mechanism 8 and the clapper mechanism 9.

[0034] Additionally, activating the fourth motor 1104 can drive the first rotating rod 1105 to rotate, thereby driving the first rotating shaft 1106 to rotate, which in turn drives the second rotating rod 1107 to shift position, thereby driving the first shifting block 1109 to shift position along the first shifting block groove 1110. This allows adjustment of the relative distance between the conveying block mechanism 8 and the clapper mechanism 9 to convey seafood of different sizes. Simultaneously, it can also drive the first shifting block 1109 to reciprocate along the first shifting block groove 1110, thereby driving the telescopic rod 1118 to reciprocate, and thus driving the conveying block mechanism 8 to reciprocate. The lifting mechanism controls the stroke of the conveying block mechanism 8. Activating the fifth motor 1111 drives the third rotating rod 1112 to rotate, which in turn drives the third rotating shaft 1113 to rotate, which in turn drives the fourth rotating rod 1114 to shift position, thereby causing the second shifting block 1116 to shift position along the second shifting block groove 1117. At the same time, it can also drive the second shifting block 1116 to move back and forth along the second shifting block groove 1117, thereby driving the lifting slide 901 to move back and forth, which in turn drives the lifting plate 902 to move back and forth, thereby patting the ice on the seafood and causing the ice on the seafood to fall off.

[0035] Example 2, see below. Figures 1-2 The conveyor box 3 is equipped with a high-pressure jet curtain 12.

[0036] Specifically, the high-pressure jet curtain 12 can be opened to seal the conveyor box 3, and the high-pressure gas can be used to separate the outside world from the conveyor box 3.

[0037] In the implementation of this invention, the high-pressure jet curtain 12 is first activated. At this time, the seafood to be transported is put into the conveying box 3, so that the seafood is placed on the conveying plate mechanism 7. Then, the reciprocating lever mechanism 10 is activated. The reciprocating lever mechanism 10 can move the positioning linkage mechanism 11. The positioning linkage mechanism 11 can drive the conveying block mechanism 8 and the clapping mechanism 9 to rise and fall synchronously, thus realizing the clapping and conveying of seafood. The knocked-off ice fragments will fall to the bottom of the conveying box 3. Activating the positioning linkage mechanism 11 can adjust the distance between the conveying block mechanism 8 and the clapping mechanism 9, thus adapting to the conveying of seafood of different sizes. At the same time, the positioning linkage mechanism 11 can also independently drive the conveying block mechanism 8 and the clapping mechanism 9 to control the independent conveying of seafood or to realize the independent clapping and de-icing of seafood.

[0038] This invention, by setting a support adjustment mechanism 2, can adjust the height of the mounting base plate 1 to adapt to different conveying positions. The reciprocating lever mechanism 10 can drive the positioning linkage mechanism 11, thereby driving the conveying block mechanism 8 and the clapping mechanism 9 to reciprocate and lift. This enables the removal of ice attached to seafood and the conveying of seafood. The positioning linkage mechanism 11 can adjust the relative position of the conveying block mechanism 8 and the clapping mechanism 9, thus adapting to the conveying and clapping of seafood of different sizes. At the same time, the conveying block mechanism 8 and the clapping mechanism 9 can be independently controlled, enriching the performance of seafood conveying.
