Description
Technical field
The utility model relates to a kind of rubber roll husker drive speed regulating device.
Background technology
The operation principle of rubber roll husker is the rubber roll by the rotation of a pair of variable speed in opposite directions, under certain pressure, to paddy by extruding with tear and rub the purpose that reaches paddy husking with the hands.The big more shell-breaking rate of the linear speed difference of two rubber rolls of rubber roll husker is just high more, and the linear speed of two rubber rolls and big more, output is just high more.According to publishing in Zhengzhou grain association on February 1st, 1992, the linear speed difference of two rubber rolls of the 1st page of narration of " design principle of the novel gearbox of rubber roll husker " book that Liu Silin, Wang Futai, Wei Guangjian, Wang Dingjun write rubber roll husker and linear speed and ratio K be one of important parameter of rubber roll husker.The 7th page of meter to the size of common stalk rice, long-grained nonglutinous rice of this book calculated K value=0.1～0.117 of long-grained nonglutinous rice, K value=0.08～0.09 of stalk rice." discussion of hulling machine structure both at home and abroad " literary composition of writing according to [grain and feed industry] 2000 the 9th phase 9-11 page or leaf Chai Wenfu of Wuxi Scientific Research and Design Inst., State Grain Reserves Bureau, introduce at present known external Japan assistant bamboo, Switzerland's cloth is reined in hulling machine and is adopted belt changed course transmission, speed change is to keep rational linear speed and linear speed poor by the rubber roll belt pulley of changing different-diameter by manpower and exchange speed roller.Hulling machine manufacturer of domestic all families, first-elected Zhuji, Zhejiang adopts the gear-box speed change to combine with belt transmission, can replace according to roller abrasion directly carrying out shift speed governing and speed roller, guarantee that two rollers have rational linear speed when different-diameter and linear speed is poor, since rubber roll be a clamping until using up, can save repeatedly roll change work and time.Yet,, must compete or be subjected to gear to limit though the gear-box speed change is good.
China's patent documentation discloses a kind of hulling machine exchange change gear box, and number of patent application is 95219917.A kind of hulling machine exchange change gear box that this patent documentation is introduced, has a casing, case lid is arranged at its top, two pairs of duplicate gears are arranged in the casing, wherein a pair of duplicate gear is made up of variable block gear wheel and pinion, and another is to being made up of fixedly gear wheel and pinion, and the two pinion diameter numbers of teeth equate, the two gear wheels also diameter number of teeth equate, and are greatly to the corresponding installation of little intersection; Case lid is provided with speed change and allots mechanism.Stir this mechanism and can make two pairs of duplicate gears greatly to little, perhaps little of big engagement, make power transmission shaft drive hulling rubber roller exchange speed change, to guarantee the rubber roll wearing and tearing evenly, it is poor to prevent to produce linear speed.
TBL5.5 gear-box that the MLGT25-A type 10 inch rubber roll huskers that Zhejiang Province Zhuji City grain and oil machinery factory produces are supporting and MLGT51 type 20 inch rubber roll huskers supporting TBSL11 gear-box to have adopted the patent No. be 95219517 patented technology.Product description according to above-mentioned hulling machine, see the list of references of submission, the 4-5 page or leaf is introduced, described hulling machine adopt speed-changing gear box carry out the speed roller alternately and speed governing guarantee that the rational linear speed of hulling machine two rubber rolls is poor, and rubber roll is once loaded onto until using up, avoid the repeatedly trouble of roll change, saved labour and time.The product description of above-mentioned hulling machine is seen the list of references of submission, the 11st page of speed change parameter list of the supporting TBL5.5 gear-box of MLGT25-A type 10 inch rubber roll huskers that Zhejiang Province Zhuji City grain and oil machinery factory produces of continuing that has been situated between.Show disclosed data rubber roll in the process that abrasion, diameter diminish according to this, change between 0.885～0.893 by speed-changing gear box speed governing K value, published on February 1st, 1992 according to Zhengzhou grain association according to aforementioned, the desired K value of stalk rice that " design principle of the novel gearbox of rubber roll husker " book that Liu Silin, Wang Futai, Wei Guangjian, Wang Dingjun write provides, this machine relatively be fit to processing stalk rice or with the similar paddy of stalk rice character.
The product description of above-mentioned hulling machine is seen the list of references of submission, the 12nd page be situated between continue MLGT51 type 20 inch rubber roll huskers that Zhejiang Province Zhuji City grain and oil machinery factory produces the speed change parameter list of supporting TBSL11 gear-box.Show disclosed data rubber roll in the process that abrasion, diameter diminish according to this, change between 0.1～0.117 by speed-changing gear box speed governing K value, published on February 1st, 1992 according to Zhengzhou grain association according to aforementioned, the desired K value of long-grained nonglutinous rice that " design principle of the novel gearbox of rubber roll husker " book that Liu Silin, Wang Futai, Wei Guangjian, Wang Dingjun write provides, this machine relatively be fit to the processing long-grained nonglutinous rice or with the similar paddy of long-grained nonglutinous rice character.
Summary of the invention
Little in order to overcome existing hulling machine gear-box slewing range, two roller linear speed differences and linear speed and the ratio K value can not be with rubber roll abrasion and the deficiency of corresponding raising, the utility model provides a kind of rubber roll husker drive speed regulating device, make two rubber rolls of same hulling machine to provide to adapt to different rice varieties rub with the hands the required linear speed of avulsion shells and, the linear speed difference and along with roller directly wear away two roller linear speed differences and linear speed and ratio K
The technical solution of the utility model is following design in order to achieve the above object:
A kind of rubber roll husker drive speed regulating device, this device are fixed on output and the power shaft, comprise driving belt and belt pulley; Belt pulley on the output shaft respectively with power shaft on belt pulley connect mutually by driving belt; It is characterized in that: described arrangements for speed regulation axially fasten by splined shaft and output shaft, power shaft and are connected or are combined into one; The outer surface of splined shaft has at least 1 groove and at least 1 spline tooth along the splined shaft axial distribution, and shifting bond(s) matches with groove by the mode that slips in the groove; Be fixed with on each splined shaft that power shaft, output shaft match equal number, at least 1 belt pulley; Belt pulley is cooperated by fixed cone dish and movable awl dish and forms, and the driving belt cross section is " V " type, and matches with " V " type concave ring groove of belt pulley; The segmentation of fixed cone dish is enclosed within outside the splined shaft, and radially is connected in by screw on the maximum gauge of spline tooth; The activity awl that matches with the fixed cone dish coils also that segmentation is enclosed within outside the splined shaft, and radially is connected on the shifting bond(s) by screw; Splined shaft is a hollow-core construction, and the right-hand member hollow part of splined shaft is fixed with the drive screw pair, and the drive screw pair comprises hold-down nut and drive screw; The hollow part inwall of hold-down nut and splined shaft closely cooperates; Hold-down nut is enclosed within outside the drive screw, and closely cooperates with drive screw; Hold-down nut radially is fastened on the splined shaft by screw, and keyboard, thrust bearing are fixed on the external part of screw rod by nut.
