Description

Technical Field

[0001] The present invention relates to a seaweed primary processing auxiliary device, in particular to a rope net continuous conveying and drying device with a cover net and a working method, belonging to the technical field of seaweed primary drying processing. Background Art

[0002] Kelp, an important seaweed, has both high edible and industrial value. Traditional primary processing methods for kelp rely primarily on drying and salting. Drying kelp is an extremely arduous and laborious process. Under the scorching sun, a rope of kelp weighing over 100 kilograms must be lifted, shaken out, and spread flat on the beach. Half a day later, the kelp needs to be turned over for drying. To reduce the amount of sand on the kelp's surface while it's being spread out, the drying area is often covered with pebbles or nets, or even with drying racks. However, the drying area is large, and workers need to move back and forth to spread and turn the kelp, which is physically demanding and can easily lead to heatstroke in the scorching sun. Furthermore, during the drying process, the material loses water, significantly reducing its weight and making it susceptible to being blown away by strong winds. Therefore, a net is needed to cover the material. However, both the covering and collecting of the nets require manual labor, which is labor-intensive and environmentally harsh.

[0003] While conventional net-chain systems can be used to construct mechanized drying systems, the high cost of stainless steel chains for long-distance transport makes them unsuitable for mechanized drying of low-value items like kelp. Furthermore, they also fail to address the issue of net cover installation. Therefore, a cost-effective, reliable mechanical structure is needed to dry low-value items while reducing the workload of operators. Summary of the Invention

[0004] The purpose of the present invention is to provide a rope net continuous conveying and drying device with a cover net and a working method. The rope net structure replaces the traditional chain net structure, which will significantly reduce the material and production costs of the device for long-distance and large-scale kelp drying. The operator spreads the kelp in situ, and the mesh automatically and stably moves forward, greatly reducing the physical effort of the drying operator to walk long distances. The kelp is placed on the net of the device, maintaining a certain distance from the ground, eliminating the path for dust and sand to adhere to the surface of the kelp, and improving the quality of materials such as kelp. The upper and lower surfaces of the kelp are free to drain moisture, and manual drying is not required, which reduces the drying process and reduces the workload. To prevent the dried kelp from being blown away by strong winds, the cover net is released along with the rope net when the kelp is spread to dry, covering the top of the kelp. After the material is dried, the cover net is retracted along with the rope net. The mechanized retraction and deployment of the cover net saves labor to the greatest extent.

[0005] The present invention specifically adopts the following technical solutions:

[0006] A rope net continuous conveying and drying device with a cover net comprises a roller rope net transmission structure and a cover net laying structure; the roller rope net transmission structure has its own power and can drive the rope net to move forward and backward, the end close to the operator is the proximal end, and the other end is the distal end; the cover net laying structure comprises a net winding disk 16 close to the proximal end for storing the cover net 15, and the head end of the cover net 15 is fixed to the rope net; in the process of the rope net moving toward the distal end, the operator gradually lays seaweed on the rope net, and at the same time, the cover net 15 is laid forward under the pulling force Fs of the rope net, and gradually covers the laid seaweed; the cover net laying structure has its own servo motor 17, and the servo motor 17 applies a cover net dragging force Fg in the net-collecting direction to the net winding disk 16, and the cover net dragging force Fg is less than the pulling force Fs of the rope net.

[0007] The roller rope net transmission structure also includes a wire rope synchronous anti-skid device I, which includes a pair of active sheaves 2 and a pair of passive sheaves 3; the active sheaves 2 and the passive sheaves 3 wrap the wire rope 4 around their own groove bodies for multiple turns and then tighten and fix it, and the wire rope 4 serves as the movement and force transmission component of the roller rope net transmission structure.

[0008] Furthermore, the rope net includes a mesh 7 and rope net cross bars 5 spaced apart on the mesh 7 , and some or all of the rope net cross bars 5 are fixedly connected to the steel rope 4 via a locking device.

[0009] Furthermore, the locking device includes a first locking member 9 for clamping the steel wire rope 4 , and a second locking member 22 vertically fixed to the first locking member 9 for clamping the rope net crossbar 5 .

[0010] Furthermore, the passive sheave 3 is located at the farthest end; the passive sheave 3 is lower than the active sheave 2; and the wire rope synchronous anti-slip device I is supported by the frame 1.

[0011] Furthermore, the density of the mesh 7 is greater than that of the cover mesh 15 .

[0012] Furthermore, the cover net 15 has mesh frames 19 on both sides, and a cover net cross bar 20 is provided at intervals in the middle; the net disk 16 is supported by a cover grid frame 18.

[0013] Furthermore, the proximal end of the roller rope net transmission structure has a roller 10, which is supported by a roller frame 11; the bracket roller and the roller 10 are both provided with raised edges and several raised small cylinders are evenly arranged on the circumference, and the column heads are hemispherical and form a circle, forming a wire rope accommodating space with the raised edges.

[0014] Preferably, it also includes a double roller bracket assembly IV, and the double roller bracket assembly IV is provided with a pair of upper and lower wire rope guide wheels for guiding the wire rope.

[0015] A working method of the above-mentioned rope net continuous conveying and drying device with a cover net, the output status of the rope net and the cover net:

[0016] The operator is located at the proximal end, and the roller rope net transmission structure drives the rope net to move toward the distal end. The operator gradually lays the seaweed on the rope net. At the same time, the cover net is laid forward under the pulling force Fs of the rope net, gradually covering the laid seaweed. During this process, because the pulling force Fg of the cover net is smaller than the pulling force Fs of the rope net, the pulling force Fs of the rope net continuously overcomes the resistance of the pulling force Fg of the cover net.

[0017] Rope net and cover net recovery status: the operator is located at the proximal end, the roller rope net transmission structure drives the rope net to move toward the proximal end, the net reel 16 that stores the cover net 15 is gradually reeled in by the servo motor 17, and the cover net moves toward the proximal end synchronously with the rope net under the action of the cover net drag force Fg; the operator gradually pulls out the seaweed between the cover net and the rope net.

[0018] The beneficial effects of the present invention are:

[0019] 1) The most basic function is to transport the net over long distances in a simple and inexpensive way. The operator simply stands still and spreads the kelp or other drying material flat on the net, and the net moves forward to quickly dry it. During harvesting, the operator can simply stand still and pick up the delivered material.

[0020] 2) A rope net structure replaces the traditional chain net structure, significantly reducing the material and manufacturing costs of kelp drying equipment over long distances and over large areas. Operators spread the kelp in situ, and the net automatically and steadily moves forward, significantly reducing the physical effort required to walk long distances. The kelp is placed on the device's net, a certain distance from the ground, eliminating the path for dust and sand to adhere to the kelp surface and improving the quality of the kelp and other materials. The upper and lower surfaces of the kelp are well drained, eliminating the need for manual turning during drying, reducing the turning process and reducing labor. To prevent the dried kelp from being blown away by strong winds, a cover net is lowered along with the rope net during drying, covering the kelp. After the material is dried, the cover net is retracted along with the rope net. The mechanized retraction and deployment of the cover net minimizes labor costs.

[0021] 3) After the wire rope has passed through the active and passive sheaves for several weeks, it will not slip after obtaining sufficient friction with the sheaves, ensuring that the two pairs of active and passive sheaves drive the left and right wire ropes to move synchronously. The crossbars of the rope net are connected to the wire ropes through three-way locks (first lock and second lock), ensuring that the crossbars are not firmly connected to the wire ropes. The combined effect of the two forms a stable fixed frame for the mesh, allowing the mesh to maintain its shape and flatness even during the movement of the wire ropes. Several ropes connect all the crossbars from the middle of the crossbar or at equal distances, supporting the middle of the mesh and suppressing sagging in the middle of the mesh.

[0022] 4) The support rollers and drum are both equipped with raised edges and several small raised cylinders evenly spaced around their circumferences. The cylinder heads are hemispherical and form a circle, forming a wire rope accommodation space with the raised edges. This limits the position of the wire rope, ensuring that the wire rope with the fixed mesh can pass through the passively rotating roller and drum accommodation space. When the mesh is placed on the drying material, the two parallel wire rope segments that form the mesh's flexible framework tend to sag and move toward each other (inward) under the influence of the material's weight. The rows of small raised cylinders, on the one hand, prevent the wire rope from moving inward, and on the other hand, precisely insert into the mesh, allowing the mesh to pass smoothly.

[0023] 5) The end of the cover net is connected to the initial section of the rope net structure. After laying the material, the cover net fits neatly over the material as the net moves forward. The servo motor drives the cover net disc to rotate, and a small reverse torque is set to provide a certain degree of damping to the cover net disc as the rope net moves forward. This solves the problem of the rope net momentarily dragging the cover net, causing the cover net disc to rotate several times due to the inertia force generated by the instantaneous drag, and excessively releasing the cover net. When retracting the rope net, the cover disc can ensure that the cover net is retracted under the action of the servo motor's reverse torque. The cover net retraction speed is set to be slightly higher than the moving speed of the retracting rope net. Under the action of the reverse torque of the reeling disc, the cover net is always kept in a retracted and taut state when the rope net is retracted.

[0024] 6) The end of the cover net can be connected to the initial section of the rope net structure via a rope hook, with the end of the rope hook fixed to the end of the cover net. During strong winds, the rope hook is used to secure the initial section of the rope net structure, and the cover net and the rope net are retracted and extended synchronously. During calm winds, the rope hook of the cover net is detached from the initial section of the rope net structure, and the cover net is in a rolled-up state, no longer retracting and extending synchronously with the rope net.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] See attached Figure 1 The rope net continuous conveying and drying device with a cover net includes a wire rope synchronous anti-slip device I, a rope net structure component II, a tail drum component III, several double roller bracket components IV, and a cover net component V; the end close to the operator is called the near end, and the end away from the operator is called the far end.

[0036] See also Figure 4 The wire rope synchronous anti-skid device I includes a frame 1, an active sheave 2 and a passive sheave 3. The outer surfaces of the active and passive sheaves are provided with several axially parallel coaxial grooves (the groove shape can be U-shaped, semicircular, V-shaped, rectangular, etc., depending on the shape of the winding object). The groove width is slightly larger than the diameter of the wire rope 4, and the wheel groove spacing is larger than the diameter of the wire rope. The groove of the driven sheave corresponds to the center of the two adjacent grooves of the active sheave. When the wire rope is connected to the active and passive sheaves, it first contacts the groove on one side of the active sheave, then reaches the groove on the same side of the passive sheave, and returns to contact the adjacent groove on one side of the active sheave after winding half a circle. It then winds around the adjacent groove on one side of the passive sheave, and returns to the active sheave after winding half a circle. This cycle continues until the grooves of the active and passive sheaves are wound and then return, forming a closed loop connection of the wire rope through several double roller bracket assemblies IV and tail drum assemblies III, such as Figure 1 and 2 shown.

[0037] The rope net structure component II is composed of two steel wire ropes 4 and several rope net cross bars 5 arranged in parallel at a certain distance to form a net laying frame. Several longitudinal reinforcing ropes 6 connect all the cross bars in series, and the mesh 7 is fixed on the frame. The cross bars are evenly distributed on the upper edge of the steel wire rope closed loop to support the mesh, and materials such as kelp 8 are laid on the net. The mesh 7 and the rope net cross bars 5 occupy a certain placement area in the steel wire rope closed loop. Before placing the material, the mesh 7 and the rope net cross bars 5 are located below the steel wire rope closed loop; when placing the material, the steel wire rope 4 drives the rope net cross bars 5 and the mesh 7 to bypass the tail drum component III and move to a section above the steel wire rope closed loop. While placing the material, the mesh, cross bars, etc. move forward until all the meshes and cross bars are transferred from the bottom of the closed loop to the top (proximal end) of the closed loop. The rope net cross bars 5 and the steel wire rope 4 are fastened together by the first locking member 9 and the second locking member 22, such as Figure 2 and 3 shown.

[0038] In the tail drum assembly III, the drum 10 is cylindrical and horizontally positioned on a drum frame 11, connected by bearings at both ends. It is unpowered. The drum has raised edges at both ends. Several small raised cylinders 12 are evenly spaced around the left and right ends of the drum. These hemispherical cylinder heads form a circle, forming a space for the wire ropes with the raised edges. Tensioning bolts are located beneath the drum frame to tighten the wire ropes on both sides.

[0039] See also Figure 5 Combined with Figure 1 The multiple dual-roller bracket assemblies IV are equipped with two upper and lower rollers 13, each with a raised edge on one end. Several small raised cylinders 14 are evenly spaced around the circumference, with hemispherical heads forming a circle. Together with the raised edge, they create a space for the wire rope. Bearings are located within the rollers, allowing them to rotate passively under the contact of the wire rope.

[0040] See also Figure 1-2 The cover net assembly V is composed of a cover net 15, a net roll 16, a servo motor 17 and a cover net frame 18. The cover net 15 is of the same length as the laying mesh 7 and is slightly narrower in width. The cover net 15 is provided with a mesh frame 19 on all four sides, and a number of equal-length cover net cross bars 20 are arranged at a certain distance in the width direction to stretch the net along the length direction of the cover net. Figure 1 One end of the cover net 15 is connected to the net reel 16, and the other end is connected to the horizontal bar at the starting end of the mesh of the rope net structure assembly. As the mesh 7 moves forward, the cover net 15 is driven out together. The servo motor 17 is set with a reverse torque of 2-5Nm. When the cover net is brought out, the net reel will passively rotate with it, but it will not excessively rotate multiple times due to inertia before stopping. When the mesh at the far end of the rope net structure assembly is recovered, the torque of the servo motor 17 causes the net reel 16 to rotate, retracting the cover net 15. The linear speed of the cover net 15 recovery is passively synchronized with the speed of the mesh recovery of the rope net structure assembly.

[0041] The steel wire rope of the rope net structure component II passes around the active and passive sheaves of the synchronous anti-skid device I, passes through the lower rollers and tail drums of several double-roller bracket assemblies, and then to the upper rollers of several double-roller bracket assemblies. The steel wire rope is connected end to end to form a runway-shaped closed loop. In the initial state, the end of the mesh of the rope net structure assembly is located at the initial end of the upper edge of the runway-shaped closed loop, and the remaining majority is located at the lower edge of the runway-shaped closed loop. The head end of the cover net is connected to the cross bar at the end of the mesh. When placing the drying materials, the operator will start to place the drying materials (such as kelp). Under power drive, the active sheave drives the steel wire rope forward, and the mesh moves forward. The subsequent mesh moves from the lower edge of the runway-shaped closed loop through the tail drum to the initial end of the upper edge of the runway-shaped closed loop for continuing to place the drying materials. At this time, the cross bar at the end of the mesh will drive the head of the cover net to move forward together and cover the drying materials on the mesh until it reaches the farthest end of the equipment. After the material is dried, the power drives the active sheave to rotate, and the wire rope moves from far to near. When the operator removes the nearby drying material, the mesh moves to the bottom edge of the runway-shaped closed loop after passing through the tail drum. The cover net drum automatically rewinds the cover net. Finally, the front end of the cover net and the end of the mesh return to their starting position.

[0042] See also Figure 6 Rope net and cover net output state: The operator is at the proximal end, and the roller rope net transmission structure drives the rope net to move toward the distal end. The operator gradually lays the seaweed on the rope net. At the same time, the cover net is laid forward under the pulling force Fs of the rope net, gradually covering the laid seaweed. During this process, because the pulling force Fg of the cover net is smaller than the pulling force Fs of the rope net, the pulling force Fs of the rope net continuously overcomes the resistance of the pulling force Fg of the cover net.

[0043] See also Figure 7 , rope net and cover net recovery status: the operator is located at the proximal end, the roller rope net transmission structure drives the rope net to move toward the proximal end, the net reel 16 that stores the cover net 15 is gradually reeled in by the servo motor 17, and the cover net moves toward the proximal end synchronously with the rope net under the action of the cover net drag force Fg; the operator gradually pulls out the seaweed between the cover net and the rope net.

[0044] The rope net of the present invention can be laid out for drying in lengths of 50 to 300 meters. Operators simply place the material, such as kelp, at the placement end of the device. The mechanical rotation gradually transports the loaded rope net toward a distance until the material covers the entire rope net. The rope net then drives the cover net above it, which is transported along the net belt. The cover net is pulled from the drum and laid directly over the material, preventing it from being blown away by strong winds. When collecting materials, the rope net can be reversed and the nearest materials can be collected one by one. A canopy can be constructed at the laying end of the device to reduce the labor of walking long distances when laying out materials and to reduce the intense sun exposure.

[0045] The above are preferred embodiments of the present invention. Those skilled in the art may make various changes or improvements based on the above. Without departing from the overall concept of the present invention, these changes or improvements should fall within the scope of protection claimed by the present invention.
