Abstract
The utility model relates to a telescopic rake for culture. The telescopic rake comprises a telescopic rod and a rake, wherein the telescopic rod is a hollow circular tube with a closed end and a pipe thread end, wherein the pipe thread of the telescopic rod is provided with a plurality of axial opening slots; the pipe thread part of the telescopic rod is provided with corresponding locking rings; an inner hole in the locking ring is an inner threaded hole which is corresponding to the pipe thread part of the corresponding telescopic rod; the telescopic rod is formed by a plurality of tubular members with different thickness; the thicker tubular member of the plurality of tubular members forming the telescopic rod is sleeved on the thinner tubular member, and the tubular members are matched with each other through transition fit; the relatively thinner telescopic rods are installed in the telescopic rod; the rake is provided with a mounting rod which is installed in the thinnest telescopic rod; the rake is formed by a plurality of hook wires which are arranged in a fan-shaped form and is installed on the other end of the mounting rod. The telescopic rake provided by the utility model has the characteristics of firm structure, easiness in operation, time and effort saving, can be widely used in the ponds of different specifications for aquaculture and scientific research.
Description
Technical field
The utility model belongs to aquaculture tool manufacturing technology field, particularly relates to the flexible rake of a kind of cultivation.
Background technology
Aquaculture had become one of the important component part of China's modern agriculture and main growth point of Rural Areas at Present economy already.Aqiuculrue is the principal mode that China raises food fish.Particularly in freshwater aquaculture industry, its total output accounts for more than 75% of national fresh-water fishes total output.For the herbivorous fishes pond culture, daily need throw something and feed a large amount of pasture and water or young tender land grass.To the remaining pasture and water in pond or land grass removing the time, tend to effectively to remove residual bait because rake is off size suitable.For the pond of different size, the raiser often needs to be equipped with the rake of different size, and the workload that this just certainly will increase the raiser has increased the weight of raiser's burden, has caused the waste of resource.Therefore, need a kind of structure more reasonable, science, practicality, remove the instrument of remaining pasture and water or land grass easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of cultivation with flexible rake,, wastes time and energy the problems such as waste resource to solve Tu Chi, cement pit or net cage in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of cultivation flexible rake, comprise expansion link and rake, described expansion link is that one of a sealing is the hollow circular-tube of gas thread, the gas thread of described expansion link has some shaft orientation opening grooves, gas thread on the described expansion link partly is equipped with corresponding retaining ring, described retaining ring endoporus is the internal thread hole corresponding with the gas thread part of corresponding expansion link, described expansion link is comprised of the some different pipe fittings of thickness, thicker pipe fitting is enclosed within thinner pipe fitting outward and becomes mutually interference fits in the pipe fitting of described some composition expansion links, relatively thin expansion link is housed in the described expansion link, described rake is installed in the expansion link the thinnest in the described expansion link with a mounting rod, described rake is made of the eave tile steel wire of the fan-shaped layout of some one-tenth, is installed in the other end of mounting rod.
The rarest 3 of the shaft orientation opening groove of the gas thread tube wall of described expansion link.
Described expansion link is made by stainless steel material.
On the described rake at least by 4 steel eave tile steel wires.
Beneficial effect
The utility model sound construction, simple to operate, time saving and energy saving; Can be widely used in the pond of different size, carry out aquaculture and scientific research activity.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of the gas thread of expansion link 1.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As illustrated in fig. 1 and 2, the flexible rake of a kind of cultivation, comprise expansion link 1 and rake 2, described expansion link 1 is that one of a sealing is the hollow circular-tube of gas thread, the gas thread of described expansion link 1 has some shaft orientation opening grooves, gas thread on the described expansion link 1 partly is equipped with corresponding retaining ring 4, described retaining ring 4 endoporus are internal thread holes corresponding with the gas thread part of corresponding expansion link 1, described expansion link 1 is comprised of the some different pipe fittings of thickness, thicker pipe fitting is enclosed within thinner pipe fitting outward and becomes mutually interference fits in the pipe fitting of described some composition expansion links 1, in the described expansion link 1 relatively thin expansion link 1 is housed, described rake 2 is installed in the expansion link 1 the thinnest in the described expansion link 1 with a mounting rod 3, described rake 2 is made of the eave tile steel wire of the fan-shaped layout of some one-tenth, is installed in the other end of mounting rod 3.
The rarest 3 of the shaft orientation opening groove of the gas thread tube wall of described expansion link 1.
Described expansion link 1 is made by stainless steel material.
On the described rake 2 at least by 4 steel eave tile steel wires.
When using the utility model to remove remaining pasture and water or land grass, can be according to the pond size, by rotation the utility model retaining ring 4, the length of adjustable telescopic rod 1, the length that adapts with selection and cement pit or net cage.
