Abstract

The utility model discloses a mechanical equipment used for the folding process of the sweep net fishing work under the ice layer. The net folding machine mainly comprises a winch net drum and a cylinder on an arch; the rear shaft of the tractor can export motive power. A netting is hoisted by the winch net drum from the net outlet ice layer and is smoothly put up on the cylinder of the arch; the netting through the cylinder is winched in flaky type and is perpendicularly downward folded on the sled of the stacking net so as to enable the netting to be tidily sent into the water under the ice layer at the net interface while the next net working. The utility model has the advantages of simple structure, convenient operation, saving the hard work of stacking the netting from the ice layer to the sled, and net folding in order.

Description

Arch-type net folding machine

The utility model is to be used for the folded employed plant equipment of net operation of subglacial haul seine fishing operation.

The fishing of subglacial haul seine is the main fishing means in each provinces and regions of northern China, also is the fishing form of solely being deposited in the world at present.In the entire job process, the strongest with folded net labour that operation is taken, still by manually on the ice face, carrying on the back the danish seine clothing, be stacked to sledge through arrangement then and get on so far.Etting is highly more folded, just piles up effort more, and folded net effect is also poor more.This folded net mode, heavy, the time-consuming weak effect of labour, sometimes even can confound etting, influence is used.

The purpose of this utility model solves exactly in the folded net operation and plays the hoisting net clothing and be aided with two labours and can fold etting like a cork, breaks away from heavy manual labor, increases work efficiency.

This net folding machine mainly is made up of two parts of the cylinder on hoisting net drum and the portal frame, be output as power with the tractor rear axle, after the double end universal coupling puts splined end, be that power has directly been passed to the hoisting net drum axle, driving the hoisting net drum rotates, there is bearing block at hoisting net roller two ends, horizontal support hoisting net drum, and bearing block is fixed on the net folding machine sledge.Hoisting net drum both sides wallboard medial surface intersects is setting the friction rubber strip, the hoisting net guide pillar that the free transfer of energy of level is arranged in hoisting net drum front upper place, simultaneously power passes to cylinder on the portal frame by two groups of sprocket wheels and a pair of speed increasing gear again, and two ends of cylinder have strand to draw the little drum of embedding form of headline and ground rope.Respectively strand draw headline, ground rope each embedding lattice sheet of the little drum of embedding form all in the even arranged crosswise of two medial surfaces of drum, embedding lattice sheet and perpendicular to the surface of drum, and according in the middle of the diameter decision embedding lattice sheet of floating, ground rope rope surplus Ullage.

The utility model has the advantages that the rotation that utilizes hoisting net drum and roller, strand is received etting relatively evenly.Because cylinder two end embedding form side drums wheels twists headline and ground rope respectively and etting is entirely drawn back and falls in the form of sheets, can make things convenient for and fitly be folded on the sledge of stacking etting, this machine is simple in structure, easy to use, only two labours can finish the former 8-10 people's of need heavy work like a cork, folded net effect is improved greatly, and has shortened and put the net time.

Accompanying drawing 1 is the structural principle schematic diagram of the utility model embodiment.

Accompanying drawing 2a-b is that the utility model is implemented the operation schematic diagram.

Specify embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in Figure 1, left-hand component is net folding machine sledge (12), and right-hand component is net wring machine sledge (13).Tractor rear axle outputting power is through the reduction box (14) of net wring machine, on one side with transmission of power to friction drum (15), be used as nettle, output power with the driving net folding machine by splined end (16) again in addition.After double end universal coupling (11) put splined end (16), promptly power was directly tied and has been passed on hoisting net drum (2) axle, drove the hoisting net drum and rotated.There are the former bearing block that fixes on the net folding machine sledge (12), horizontal support hoisting net drum (2) in hoisting net drum two ends.Hoisting net drum both sides wallboard medial surface intersects is setting the friction rubber strip.Increase pulling force for increasing hoisting net drum hoisting net cornerite, establish the hoisting net guide pillar (9) of the free transfer of energy of a level in its front upper place.Power by the sprocket wheel on the axle, is passed to the cylinder (3) on the portal frame (6) again.Chain wheel set (5) is divided two groups up and down, influences the transmission effect to avoid long the hanging of chain.The lower sprocket group is passed to the cochain wheels by a pair of speed increasing gear (8) with power again simultaneously, like this, cylinder (3) turn to switched in opposite with hoisting net drum (2), the volume twisted wire speed that can make cylinder (3) again is slightly greater than the hoisting net linear velocity of hoisting net drum (2), thereby make the etting between hoisting net drum (2) and the cylinder (3) be in tensioning state, be unlikely making etting sagging.There is the little drum of embedding form (4) of strand rock guiding principle and ground rope at the two ends of cylinder (3), strand is drawn headline respectively, each embedding lattice sheet of the little drum of embedding form of ground rope is all in the even arranged crosswise of two medial surfaces of drum, the embedding form is perpendicular to the surface of drum, and according to the quantity of the diameter decision embedding lattice sheet of the size of floating, sinker and floating, heavy guiding principle and embedding lattice sheet surplus Ullage.When strand is folded net, two operating personnels in two limits each proficiency is taken headline or ground rope, set foot on both sides pedal (1) and the guiding principle rope is costed the little drum of embedding lattice (4) of cylinder (3) two ends, float and sinker are embedded in each embedding compartment, the guiding principle rope is then curved to be embedded in the Ullage of lattice in the middle of sheet, when cylinder (3) rotates, and floating, ground rope slippage backward, to help an etting constantly to roll up heave in effectively, and with etting.Entirely draw back, etting is fallen in the form of sheets, and two operating personnels in two limits constantly haul etting, the constantly folding action of promptly finishing folding etting.Fig. 2 is this machine operation schematic diagram, and Fig. 2 (6) after by tractor two sledges being dragged to the operation area, is parked in out the network interface place with net wring machine sledge (13), the tractor winch strand guiding principle of tending to act separately.Fig. 2 (a) when being hauling line shaft connected good after, again with pin with net folding machine " sledge (12) is fixed on the ice face, continuous hoisting net, constantly folding etting.

When shifting the fishing ground, the connection of the power of two sledges is unloaded, and double end universal joint shaft (11) is hung on the hook of portal frame, with connecting pin (10) two sledges is connected, and is pulled by tractor.
