A net machine net-retrieving mechanism with a maintenance passage

Abstract

This utility model relates to the field of fishing net machine technology, specifically to a fishing net machine hauling mechanism with a maintenance passage. It includes a support platform fixedly connected to the body of the fishing net machine. The support platform is located directly above the area between adjacent hauling rollers on the fishing net machine. There is a certain height difference between the bottom of the support platform and the net sheet on the surface of the lower hauling roller to prevent the net sheet from contacting the bottom of the support platform. The support platform extends axially along the hauling rollers, forming a maintenance passage that allows access to the fishing net machine's maintenance area. This utility model, by installing a support platform at the existing fishing net machine's hauling mechanism, prevents workers from being blocked by the net sheet when a malfunction occurs in the hauling mechanism. Because the support platform is located above the hauling rollers and the net sheet, workers can walk through the maintenance passage on the support platform without being prevented from entering the maintenance area by the net sheet. Maintenance can be performed without disassembling or damaging the net sheet, thus improving efficiency.

Description

Technical Field

[0001] This utility model relates to the field of fishing net machine technology, and in particular to a fishing net machine net-collecting mechanism with a maintenance channel. Background Technology

[0002] Currently, during fishing net machine maintenance, the netting between the winding rollers at the retrieval mechanism can become an obstacle, preventing workers from accessing the maintenance area. To address this, the industry commonly employs two methods: directly removing the netting or cutting a notch in the obstructing portion to open a maintenance channel. Both methods have drawbacks: the first method, while opening the channel, causes the netting to detach from the winding rollers, requiring reconnection during subsequent winding; the second method damages the netting, resulting in waste. Therefore, neither is an ideal solution. There is an urgent need to design a technical solution that allows for barrier-free maintenance of fishing net machines without removing or damaging the netting. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a net-collecting mechanism for a fishing net machine with a maintenance channel, so as to solve the technical problem that existing fishing net machines require the removal or destruction of the nets when they are being repaired because the nets can obstruct access to the maintenance area.

[0004] To achieve the above objectives, this utility model provides a fishing net retrieval mechanism with a maintenance channel, including a support platform fixedly connected to the body of the fishing net machine. The support platform is located directly above the area between adjacent take-up rollers on the fishing net machine. There is a certain height difference between the bottom of the support platform and the net sheet on the surface of the take-up roller below, so as to prevent the net sheet from contacting the bottom of the support platform. The support platform extends along the axial direction of the take-up roller and forms a maintenance channel that allows access to the maintenance area of ​​the fishing net machine. During maintenance operations, operators can pass through the maintenance channel to bypass the net sheet and enter the maintenance area of ​​the fishing net machine without obstruction.

[0005] As a preferred embodiment of this utility model, the support platform includes:

[0006] The crossbeams, having at least two, are arranged on the machine body at relative intervals, the lengths of the two machine bodies extending along the axial direction of the take-up roller;

[0007] A pad is fixedly laid on the two beams and fills the gap.

[0008] As a preferred embodiment of this utility model, a first positioning hole is provided on the surface of the crossbeam, and a second positioning hole corresponding to the first positioning hole is provided on the surface of the body. A first positioning element for connecting the two is provided in the first positioning hole and the second positioning hole.

[0009] As a preferred embodiment of this utility model, the surface of the pad is provided with a third positioning hole, and the surface of the crossbeam is provided with a fourth positioning hole corresponding to the third positioning hole. A second positioning element for connecting the two is provided in the third positioning hole and the fourth positioning hole.

[0010] As a preferred embodiment of this utility model, the pad has multiple pads arranged sequentially along the length of the crossbeam.

[0011] As a preferred technical solution of this utility model, the upper end of the pad is provided with an anti-slip structure, and the two sides of the support platform are provided with guardrails.

[0012] As a preferred embodiment of this utility model, the net-collecting mechanism of the fishing net machine further includes:

[0013] A bracket is fixed at one end to one side of the crossbeam, and the other end of the bracket extends toward the take-up roller;

[0014] At least two rollers are rotatably disposed at one end of the bracket near the take-up roller, and the rollers are in rolling contact with the take-up roller.

[0015] As a preferred embodiment of this utility model, the bracket is connected to a mounting plate on the side near the crossbeam. The surface of the mounting plate is provided with a fifth positioning hole, and the surface of the crossbeam is provided with a sixth positioning hole corresponding to the fifth positioning hole. A third positioning element for connecting the two is provided in the fifth positioning hole and the sixth positioning hole.

[0016] The beneficial effects of this utility model are as follows: By installing a support platform at the net-collecting mechanism of an existing fishing net machine, when a malfunction occurs at the net-collecting mechanism, the support platform, located above the winding roller and the net, allows workers to access the maintenance area without being obstructed by the net when walking along the maintenance passage on the support platform. Furthermore, the height difference between the support platform and the winding roller and net prevents the net from rubbing against the bottom of the support platform when the winding roller drives the net to collect it, eliminating the need to disassemble or damage the net during maintenance and improving efficiency.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0026] like Figure 1 and Figure 2As shown, a fishing net retrieval mechanism with a maintenance channel includes a support platform fixedly connected to the body 1 of the fishing net machine. The support platform is located directly above the area between adjacent take-up rollers 15 on the fishing net machine. There is a certain height difference between the bottom of the support platform and the net sheet on the surface of the lower take-up roller 15 to prevent the net sheet from contacting the bottom of the support platform. The support platform extends along the axial direction of the take-up roller 15 and forms a maintenance channel that allows access to the maintenance area of ​​the fishing net machine. During maintenance operations, operators can pass through the maintenance channel to enter the maintenance area of ​​the fishing net machine without obstruction by avoiding the net sheet.

[0027] The above technical solution allows operators to easily access the maintenance area of ​​the fishing net machine. When a malfunction occurs in the net-collecting mechanism, operators can step onto the support platform and enter the maintenance area along the maintenance passage formed at the top of the support platform. Since the support platform is located above the winding roller 15 and the net, operators will not be hindered by the net when walking on the maintenance passage on the support platform. At the same time, due to the height difference between the support platform, the winding roller 15, and the net, the net will not rub against the bottom of the support platform when the winding roller 15 drives the net to collect the net, preventing wear and tear on the net. Therefore, by setting up a support platform at the existing net-collecting mechanism of the fishing net machine, the problem of operators having difficulty entering the maintenance area due to the obstruction of the net can be effectively solved. There is no need to disassemble or damage the net, thus improving maintenance efficiency.

[0028] like Figure 2 and Figure 3 As shown, in this embodiment, the support platform includes: crossbeams 2, having at least two, and arranged on the machine body 1 at relative intervals, the lengths of the two machine bodies 1 extending along the axial direction of the winding roller 15; and pads 6 fixedly laid on the two crossbeams 2 and filling the gaps.

[0029] The above technical solution can provide support for workers by setting two crossbeams 2, while the pad 6 can seal the gap between the two crossbeams 2, preventing workers from stepping into empty spaces and increasing safety.

[0030] like Figure 4 As shown, in this embodiment, the surface of the crossbeam 2 is provided with a first positioning hole 4, and the surface of the body 1 is provided with a second positioning hole 5 corresponding to the first positioning hole 4. A first positioning element 3 for connecting the two is provided in the first positioning hole 4 and the second positioning hole 5. The surface of the pad 6 is provided with a third positioning hole 8, and the surface of the crossbeam 2 is provided with a fourth positioning hole 9 corresponding to the third positioning hole 8. A second positioning element 7 for connecting the two is provided in the third positioning hole 8 and the fourth positioning hole 9. The first positioning element 3 and the second positioning element 7 are bolts, and the first positioning hole 4, the second positioning hole 5, the third positioning hole 8 and the fourth positioning hole 9 are all threaded holes.

[0031] The above technical solution allows the crossbeam 2 to be fixed to the body 1 with bolts, and the pad 6 to be installed on the crossbeam 2. During installation, the two crossbeams 2, which serve as load-bearing structures, are first placed horizontally and parallel on the body 1, ensuring that the first positioning hole 4 on the crossbeam 2 is aligned with the second positioning hole 5 on the body 1. Then, the first positioning piece 3 is inserted into the first positioning hole 4 and the second positioning hole 5 in sequence to fix the crossbeam 2 to the body 1. Subsequently, the pad 6 is placed on the crossbeam 2, ensuring that the third positioning hole 8 on the pad 6 is aligned with the fourth positioning hole 9 on the crossbeam 2. Then, the second positioning piece 7 is inserted into the third positioning hole 8 and the fourth positioning hole 9 in sequence. Each pad 6 needs to be fixed in at least four places to fix the pad 6 to the crossbeam 2.

[0032] like Figure 3 As shown, in this embodiment, there are multiple pads 6 arranged sequentially along the length of the crossbeam 2;

[0033] The above technical solution can ensure that the support platform can achieve modular design. Since the two crossbeams 2 are spaced apart, the middle area of ​​the pad 6 lacks support. When the operator steps on the pad 6, it will put pressure on the pad 6. Over time, the middle part of the pad 6 will dent. Therefore, the pad 6 is easy to be damaged and needs to be replaced regularly. After the pad 6 is made into a modular design, only the damaged part needs to be replaced, which helps to reduce maintenance costs.

[0034] like Figure 3 As shown, in this embodiment, the upper end of the pad 6 is provided with an anti-slip structure, which is an anti-slip texture or an anti-slip protrusion. The two sides of the support platform are provided with guardrails, which are not shown in the figure. The cross-section of the beam 2 is an "L" shaped structure.

[0035] The above technical solution can help improve the surface roughness of the pad 6 and prevent workers from slipping due to the excessive smoothness of the pad 6 surface. In order to further improve the safety of operation, guardrails can also be installed on both sides of the crossbeam 2.

[0036] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the net-collecting mechanism of the fishing net machine further includes: a bracket 11 fixedly disposed on one side of the crossbeam 2, and the other end of the bracket 11 extending toward the take-up roller 15; at least two rollers 12, which are rotatably disposed on one end of the bracket 11 near the take-up roller 15, and the rollers 12 are in rolling contact with the take-up roller 15.

[0037] The above technical solution can ensure that the take-up roller 15 will not bend. Since the take-up roller 15 is long, when only the two ends are fixed, the middle part lacks support and is prone to deformation and bending. Therefore, the bracket 11 and roller 12 are set to provide rolling support for the middle part of the take-up roller 15. The two rollers 12 can form a stable support for the take-up roller 15. At the same time, the friction is smaller when rolling and contacting, and the take-up roller 15 is less likely to wear.

[0038] like Figure 5 As shown, in this embodiment, a mounting plate 10 is connected to the side of the bracket 11 near the crossbeam 2. A fifth positioning hole 14 is opened on the surface of the mounting plate 10, and a sixth positioning hole corresponding to the fifth positioning hole 14 is opened on the surface of the crossbeam 2. A third positioning member 13 for connecting the two is provided in the fifth positioning hole 14 and the sixth positioning hole. The third positioning member 13 is a bolt, and the fifth positioning hole 14 and the sixth positioning hole are threaded holes.

[0039] The above technical solution allows the bracket 11 to be connected to the crossbeam 2 by bolts.

[0040] Working principle:

[0041] Before use, first install the support platform at the net-collecting mechanism of the fishing net machine. First, place the two crossbeams 2, which serve as the load-bearing structure, horizontally and parallel on the machine body 1, ensuring that the first positioning hole 4 on the crossbeam 2 is aligned with the second positioning hole 5 on the machine body 1. Then, use the first positioning piece 3 to pass through the first positioning hole 4 and the second positioning hole 5 in sequence to fix the crossbeam 2 on the machine body 1. Next, place the pad 6 on the crossbeam 2, ensuring that the third positioning hole 8 on the pad 6 is aligned with the fourth positioning hole 9 on the crossbeam 2. Then, use the second positioning piece 7 to pass through the third positioning hole 8 and the fourth positioning hole 9 in sequence. Each pad 6 should be fixed in at least four places to fix the pad 6 on the crossbeam 2.

[0042] When a malfunction occurs in the net-collecting mechanism of a fishing net machine, the operator steps onto the platform 6 to enter the maintenance area. Since the platform 6 and the crossbeam 2 are both located above the winding roller 15 and the net, the operator's movement is not hindered by the net when walking on the platform 6. At the same time, due to the height difference between the platform 6 and the crossbeam 2 and the winding roller 15 and the net, the net will not rub against the bottom of the platform 6 and the crossbeam 2 when the winding roller 15 drives the net to collect the net, thus preventing wear on the net. Therefore, by setting up a support platform consisting of the platform 6 and the crossbeam 2 at the net-collecting mechanism of the existing fishing net machine, the problem of the operator's inability to enter the maintenance area due to the obstruction of the net can be effectively solved. Of course, the support platform can also be a one-piece structure, such as the platform 6 and the crossbeam 2 being integrally formed into a U-shaped structure, which eliminates the need to disassemble and damage the net, improving maintenance efficiency.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
