CN203538150U - Net hauler roller capable of increasing friction - Google Patents

Abstract

The utility model discloses a net hauler roller capable of increasing friction. The net hauler roller is characterized by comprising a revolving shaft and a roller body (1); the roller body (1) is fusiform; the middle part of the roller body (1) is bigger than both ends of the roller body (1) in diameter; a rubber layer (2) is arranged outside the roller body (1); one end of the roller body (1) is also provided with a steel ring (3), and the diameter of the steel ring (3) is smaller than the maximum diameter of the roller body (1). The net hauler roller has the advantages that the structure is simple, the design is skillful, the layout is reasonable, and a headline on a net can pass on the premise that the friction between the roller body and the net is increased.

Description

Can improve the net hauler cylinder of frictional force

Technical field

The utility model relates to a kind of net hauler roller frame, particularly a kind of net hauler cylinder that improves frictional force.

Background technology

On purse seiner, being provided with can be by the net hauler of fishing net pull-up from water, and the dynamic structure of net hauler is net hauler cylinder, in the process that net hauler cylinder rotates, under the effect of frictional force, drives net sports to realize hauling action.Because the weight of etting itself is larger, add the fish in etting, therefore the needed strength of mobile etting is very large, and so just needing will have enough frictional force between net hauler cylinder and etting; And traditional net hauler cylinder and the frictional force between etting are often not enough, often there will be the phenomenon of skidding, dallying; On etting, be also provided with headline, headline often can be difficult to by net hauler cylinder in the process with etting motion, affects hauling effect simultaneously.Therefore need now a kind of net hauler roller frame that can address the above problem.

Utility model content

The utility model is in order to solve the existing above-mentioned deficiency of prior art, propose a kind of simple in structure, design ingenious, rationally distributed, can increase and etting between under the prerequisite of frictional force, do not affect the net hauler cylinder that on etting, headline passes through.

Technical solution of the present utility model is: a kind of net hauler cylinder that improves frictional force, it is characterized in that: described cylinder comprises rotating shaft and barrel 1, described 1 one-tenth fusiformis of barrel, its middle part diameter is greater than two ends diameter, at barrel 1, be outside equipped with rubber layer 2, one end of barrel 1 is also provided with steel loop 3, and the diameter of steel loop 3 is less than the maximum gauge of barrel 1.

Compared with the existing technology, tool has the following advantages the utility model:

The net hauler cylinder of the improved frictional force of this kind of version, it is simple in structure, design ingenious, it for traditional net hauler cylinder in use, due to and etting between frictional force not enough, cause skid, the phenomenon such as idle running and the normal situation of hauling, the shape of cylinder is designed to fusiformis small in the end and big in the middle, in the outside of barrel, increased the rubber layer that can improve frictional force, these two kinds of structural improvement can both effectively increase the frictional force between barrel and etting simultaneously.Simultaneously in order to prevent that the headline on etting from impacting when contacting with barrel, is also provided with in one end of barrel the steel loop that diameter is relatively little.The manufacture craft of this net hauler cylinder is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of net hauler cylinder that improves frictional force, this roller frame comprises a rotating shaft and is arranged in rotating shaft and the barrel 1 thereupon rotating, 1 one-tenth fusiformis of this barrel, it is the diameter that the diameter of intermediate portion is greater than two end portions, and be also provided with rubber layer 2 in barrel 1 outside, and one end of barrel 1 is also provided with steel loop 3, the diameter of this steel loop 3 is less than the maximum gauge at barrel 1 middle part.

Because the diameter of barrel 1 mid portion is greater than the diameter of two end portions, can increase the frictional force between etting and barrel 1, and the rubber layer 2 in barrel 1 arranged outside also can increase this part frictional force, to prevent the generation of the situations such as cylinder dallies, skids; And the steel loop 3 that is arranged on barrel 1 one end is because its diameter is less than the maximum gauge of barrel 1, and steel loop 3 is smooth surface, therefore can allow the headline on etting pass through smoothly.

Claims (1)

1. the net hauler cylinder that can improve frictional force, it is characterized in that: described cylinder comprises rotating shaft and barrel (1), described barrel (1) becomes fusiformis, its middle part diameter is greater than two ends diameter, at barrel (1), be outside equipped with rubber layer (2), one end of barrel (1) is also provided with steel loop (3), and the diameter of steel loop (3) is less than the maximum gauge of barrel (1).
