Description

Technical Field

[0001] The present invention relates to the technical field of sea intestine fishing, and particularly to an intelligent unmanned sea intestine fishing machine. Background Art

[0002] The sea intestine (scientific name: Urechis unicinctus) is a marine organism with high protein (15%-20%) and low fat, rich in taurine, arginine, zinc, iron and other minerals and vitamins, and has both nutritional and medicinal values. It inhabits the sandy seabed in shallow waters and relies on swallowing sediment organic matter to maintain ecological functions.

[0003] Sea intestine fishing mostly adopts two methods: manual fishing and water pump fishing. Among them, manual fishing needs to be carried out by manually digging sand and filtering. The fishing efficiency of this method is low, the manual labor intensity is high, and the labor cost is high. When using the water pump fishing method, in order to blow up the sediment, a water pump with a large flow rate and high lift needs to be selected. Although this kind of water pump can blow up the sediment, due to its too large impact force, it is extremely easy to cause the death and damage of sea intestines, and there is also the problem of low fishing efficiency.

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1 - 12 shown, the present invention provides an intelligent unmanned sea cucumber fishing machine, which includes an unmanned tractor 1, a sand turning plow 2 and a sea cucumber sieve 3. The unmanned tractor 1 provides traction power and can control the traction activity of the unmanned tractor 1 by means of remote control. The sand turning plow 2 is used for sand turning operation in the fishing ground, and its purpose is to turn out sea cucumbers from the sand. The sea cucumber sieve 3 is used for filtering sea cucumbers and filtering out sediment.

[0033] The driverless tractor 1 includes a driving chassis 11 and a sealed cabin cover 12. The sealed cabin cover 12 is installed on top of the driving chassis 11. Inside the sealed cabin cover 12, there are an engine 13, a gear pump 14, a valve plate assembly 15, and a hydraulic oil tank 16. The engine 13 is a twin-cylinder engine that provides sufficient power for the gear pump 14. The core function of the gear pump 14 is energy conversion and oil delivery. The gear pump 14 rotates through the meshing of the driving gear and the driven gear, forms a partial vacuum in the oil suction chamber to suck in oil, and outputs high-pressure oil through volume compression in the oil pressure chamber. This process converts mechanical energy into hydraulic energy to provide hydraulic power support for the unmanned sea cucumber harvester. The valve plate assembly 15 is used to achieve flow and hydraulic control. The valve plate assembly 15 integrates components such as an overflow valve and a direction valve, and adjusts the oil flow direction and pressure to match the load requirements. The hydraulic oil tank 16 is used for oil storage and supply. The hydraulic oil tank 16 stores hydraulic oil and continuously supplies oil to the gear pump to ensure the required flow rate in the pump's oil suction chamber.

[0034] The gear pump 14 sucks oil from the hydraulic oil tank 16, outputs high-pressure oil to the valve plate assembly 15. The valve plate assembly 15 diverts the oil to the actuators (such as hydraulic pumps and swing cylinders), and limits the system pressure through the overflow valve to ensure safety. After the actuators complete their actions, the oil returns to the hydraulic oil tank 16 through the circuit, and is cooled and filtered before being recycled.

[0035] In the middle of the upper cover of the sealed cabin cover 12, there are a filter 131, an exhaust pipe 132, and a cooling fan 133. At the front end of the upper cover of the sealed cabin cover 12, there is a GPS antenna 18. At the rear end of the upper cover of the sealed cabin cover 12, there is a monitoring pan-tilt 17. The monitoring pan-tilt 17 realizes multi-angle and intelligent monitoring through the linkage of the mechanical structure and the camera. It realizes horizontal and vertical dual-axis movement through two groups of motors, can cover the monitoring requirements of the three-dimensional space, and the monitoring pan-tilt 17 provides visual support for the commander to remotely operate the driverless tractor 1.

[0036] At the front and rear ends of the sealed cabin cover 12, there are searchlights 121. The searchlights 121 provide a lighting source for the monitoring pan-tilt 17, facilitating the operator to remotely monitor the on-site fishing situation.

[0037] The driving chassis 11 includes a vehicle support 111, a driving wheel mechanism 114, a tensioning wheel mechanism 115, a floating wheel mechanism 116, and a crawler 117. The vehicle support 111 is the support structure of the entire driving chassis 11. On both sides of the lower end of the vehicle support 111, there are lower fixed wheels 112 respectively. In the middle of the upper end of the vehicle support 111, there is an upper fixed wheel 1113.

[0038] The drive wheel mechanism 114 is installed at one end above the vehicle support 111. The drive wheel mechanism 114 includes a hydraulic pump base 1141, a hydraulic pump 1142, and a drive wheel 1143. The drive wheel mechanism 114 is fixedly connected to the vehicle support 111 through the hydraulic pump base 1141. A hydraulic pump 1142 is installed on one side of the hydraulic pump base 1141, and a drive wheel 1143 is installed on the other side of the hydraulic pump base 1141. Sufficient traction power has been achieved through hydraulic drive.

[0039] The tensioning wheel mechanism 115 is installed at the other end above the vehicle support 111. The tensioning wheel mechanism 115 includes a fixed sleeve 1151, a tensioning pipe frame 1152, a plug plate 1153, a tensioning bolt 1154, and a tensioning wheel 1155. The fixed sleeve 1151 is fixedly connected to the vehicle support 111. One end of the tensioning pipe frame 1152 is inserted into the fixed sleeve 1151 and is threadedly connected to the tensioning bolt 1154. The other end of the tensioning pipe frame 1152 is used to install the tensioning wheel 1155. The tensioning bolt 1154 is connected to the fixed sleeve 1151 through the plug plate 1153. The position of the tensioning wheel 1155 is adjusted by rotating the tensioning bolt 1154 clockwise or counterclockwise, thereby adjusting the magnitude of the tensioning force.

[0040] The floating wheel mechanism 116 is installed in the middle of the lower end of the vehicle support 111. The number of floating wheel mechanisms 116 is multiple. The floating wheel mechanism 116 includes a floating frame 1161 and a floating wheel 1162. The floating frame 1161 is a V-shaped support. The middle of the floating frame 1161 is rotatably connected to the vehicle support 111. Floating wheels 1162 are installed at both ends of the floating frame 1161. The obstacle-crossing ability of the unmanned tractor is improved through the floating wheel mechanism 116 to adapt to the complex beach operation environment.

[0041] The crawler 117 is installed above the lower fixed wheel 112, the upper fixed wheel 1113, the drive wheel 1143, the tensioning wheel 1155, and the floating wheel 1162. The crawler 117 is made of a material with anti-corrosion and high mechanical strength.

[0042] The rear end of the vehicle support 111 is used to install and connect the sand turning plow 2. The rear end of the vehicle support 111 is provided with a front swing arm seat 1111 and a swing cylinder seat 1112. The sand turning plow 2 includes a plow frame 21. The front end of the upper frame of the plow frame 21 is provided with a rear swing arm seat 211. The number of the front swing arm seat 1111 and the rear swing arm seat 211 is 2. A swing arm 22 is provided between the front swing arm seat 1111 and the rear swing arm seat 211. The two swing arms 22 are symmetrically arranged. In order to adjust the turning angle and turning depth of the sand turning plow 2, the swing arms 22 are respectively rotatably connected to the front swing arm seat 1111 and the rear swing arm seat 211 through a rotating shaft.

[0043] The front support arms 23 are installed on the upper parts of the two rear swing arm seats 211. The upper ends of the two front support arms 23 are fixedly connected by a rotating shaft. The lower ends of the two front support arms 23 are rotatably connected to the rear swing arm seats 211. A rear support arm 24 is provided between the upper end of the front support arm 23 and the rear end of the upper frame of the plow frame 21. The two ends of the rear support arm 24 are respectively rotatably connected to the front support arm 23 and the plow frame 21. A swing oil cylinder 25 is provided between the upper end of the front support arm 23 and the swing cylinder seat 1112. The cylinder body and the piston rod of the swing oil cylinder 25 are respectively rotatably connected to the swing cylinder seat 1112 and the front support arm 23.

[0044] When controlling the telescopic movement of the swing oil cylinder 25, the plow frame 21 will rotate around the front swing arm seat 1111 and the rear swing arm seat 211 respectively, thereby adjusting the sand turning depth and sand turning angle of the plow frame 21.

[0045] In order to increase the adjustment range of the sand turning depth and sand turning angle of the plow frame 21, a plurality of swing arm shaft holes 2111 are provided on the rear swing arm seat 211. By switching different swing arm shaft holes 2111 to install the swing arm 22 and the front support arm 23, when the telescopic amount of the swing oil cylinder 25 is the same, the sand turning depth and sand turning angle of the plow frame 21 will be different.

[0046] Similarly, a plurality of support arm shaft holes 231 are provided at the upper end of the front support arm 23. By switching different support arm shaft holes 231 to install the swing oil cylinder 25 and the rear support arm 24, when the telescopic amount of the swing oil cylinder 25 is the same, the sand turning depth and sand turning angle of the plow frame 21 will be different.

[0047] Therefore, the sand turning depth and sand turning angle of the plow frame 21 can be flexibly adjusted according to the distribution depth of sea cucumbers and the water content of the sandy land in the sea cucumber fishing ground, so as to improve the effect of sea cucumber fishing.

[0048] The lower end of the plow frame 21 is designed with two rows of front and rear plow blades, namely evenly distributed front plow blades 212 and rear plow blades 213. The front plow blades 212 and the rear plow blades 213 are respectively fixed to the lower end of the plow frame 21 through plow columns. The front plow blades 212 and the rear plow blades 213 include triangular plow blade parts and rectangular plow blade parts. The triangular plow blade parts are located at both ends of the rectangular plow blade parts. The top of the upper triangular plow blade part is fixed together with the plow column. The front plow blades 212 and the rear plow blades 213 are arranged at intervals in turn. After the sediment is turned up by the front plow blades 212, the sediment is further dispersed by the rear plow blades 213 so as to separate the sea cucumbers from the sediment.

[0049] The sea intestine sieve mesh 3 is a rigid steel mesh. The sea intestine sieve mesh 3 has a structure that is wider at the front and narrower at the rear. The sea intestine sieve mesh 3 includes an upper sieve plate 31 and a lower sieve plate 32. The front ends of the upper sieve plate 31 and the lower sieve plate 32 are fixedly connected through a left sieve plate 33 and a right sieve plate 34. The rear ends of the upper sieve plate 31 and the lower sieve plate 32 are fixedly connected through a tail plate 37. A left inclined sieve plate 35 is provided between the left sieve plate 33 and the tail plate 37, and a right inclined sieve plate 36 is provided between the right sieve plate 34 and the tail plate 37.

[0050] The upper sieve plate 31, the lower sieve plate 32, the left sieve plate 33, the right sieve plate 34, the left inclined sieve plate 35 and the right inclined sieve plate 36 are provided with long strip-shaped sieve holes. The advantage of the long strip-shaped sieve holes is that it is beneficial to the filtration of sediment and reduces the resistance of sediment filtration. If round-hole-shaped sieve holes are used, it is found in experiments that the resistance of sand filtration is very large and it is easy to be blocked, especially when the water content of the sediment is low. In the present invention, the sieve holes of the upper sieve plate are designed as long strip-shaped, which creatively solves the problems of large sediment resistance and easy blockage.

[0051] No sieve holes are designed on the tail plate 37. The main reason is to protect the sea intestine and avoid damage to the sea intestine. If sieve holes are designed on the tail plate 37, since the scouring force of sediment is the greatest at the tail plate 37, the scouring force of sediment filtration will damage the sea intestine.

[0052] An intelligent unmanned sea intestine fishing machine of the present invention includes an unmanned tractor 1, a sand turning plow 2 and a sea intestine sieve mesh 3. The operator controls the traction activity of the unmanned tractor 1 by means of remote control, and conducts sea intestine fishing by means of remote control, realizing the automation and intelligence of sea intestine fishing, improving the efficiency of sea intestine fishing, and reducing the manual labor intensity and labor cost of sea intestine fishing.

[0053] The sand turning depth and sand turning angle of the sand turning plow 2 are remotely controlled by the telescopic movement of a swing oil cylinder 25. According to the distribution depth of sea intestines and the water content of the sandy land in the sea intestine fishing site, the sand turning depth and sand turning angle of the plow frame 21 are flexibly adjusted to improve the effect of sea intestine fishing. The sea intestine sieve mesh 3 is a rigid steel mesh. The sea intestine sieve mesh 3 has a structure that is wider at the front and narrower at the rear. The sieve plate of the sea intestine sieve mesh 3 is provided with long strip-shaped sieve holes, which are beneficial to the filtration of sediment and reduce the resistance of sediment filtration. No sieve holes are designed on the tail plate 37 of the sea intestine sieve mesh 3 to avoid damage to the sea intestine.

[0054] Only as described above are specific embodiments of the present invention. The scope of implementation of the present invention cannot be limited thereby. Therefore, the replacement of equivalent components or equivalent changes and modifications made according to the scope of protection of the present invention shall still fall within the scope covered by the claims of the present invention.
