Abstract
The invention relates to the field of agriculture machinery and discloses a telescopic seedling pulling wheel device. The design solves the problems of pulling missing, blockage and small seedling pulling range during the corn harvesting. Through the adoption of double seedling pulling wheels for seedling pulling and the change of the extending length of pulling teeth, the seedling pulling range expansion is realized, and meanwhile, the seedling pulling wheels in pairs are placed at different heights so that the dimension of the seedling pulling wheels is increased. The device comprises worm-and-gear transmission boxes, a main seedling pulling wheel, the pulling teeth, a stop block and a cam, wherein one ends of the two worm-and-gear transmission boxes are connected onto corresponding ear picking rollers, the other ends of the two worm-and-gear transmission boxes are connected with a guide cone, the side surfaces of the worm-and-gear transmission boxes are hinged onto a machine frame through screw bolts, the stop block and the cam are welded onto the machine frame in a welding mode, the main seedling pulling wheel and the pulling teeth are arranged on the seedling pulling shaft extending out from the transmission box, and corn plants are smoothly pulled into the ear pulling roller through the telescopic effect of the pulling teeth and the effect of the main pulling wheel during the work.
Description
Technical field
What the present invention relates to is a kind of extension type straw shift wheel device, and this straw shift wheel device can be realized dialling the standing grain effect preferably in harvest corn to milpa, belongs to agricultural mechanical field.
Background technology
At present, the associating maize harvesting machine on the market is rice-pulling chain formula and straw shift wheel formula mostly, and wherein the straw shift wheel formula comprises that single straw shift wheel formula and double seedling are wheeled.Chain type is dialled the standing grain device has limited harvest machinery owing to the size of the dynamics of dialling standing grain and scope pace; Simultaneously the cost of rice-pulling chain higher, easy to wear, be prone to elongation, transmission stability is poor; Need timely tightener sprocket at work, can reduce operating efficiency like this, and have influence on operation quality.Simultaneously because the disunity of China's corn planting line-spacing brings big difficulty to harvest corn.The straw shift wheel formula is dialled the standing grain device and is existed the leakage of milpa to dial, stop up and dial problems such as the standing grain scope is less during harvest corn.The maize harvesting machine of single straw shift wheel formula has increased the diameter of straw shift wheel in order to increase the working range of straw shift wheel, and structure is improper can influence perhaps disturb corn before leaving, produces yield loss.The maize harvesting machine that double seedling is wheeled, the spacing of the limited size of straw shift wheel between snapping bar dialled the standing grain device simultaneously and placed at grade mostly; Make the size of straw shift wheel and the sphere of action of group standing grain be restricted; Dial the standing grain poor effect, be easy to produce leak and dial phenomenon, even be placed on the Different Plane; The sphere of action of the size of straw shift wheel and group standing grain also can be limited, is difficult to group standing grain effect that reaches desirable.
Variation through adopting the double seedling wheel to dial standing grain and moving tooth extension elongation has realized the expansion of group standing grain scope, and paired straw shift wheel of while is placed on different height makes the size of straw shift wheel increase to some extent.
Summary of the invention
The objective of the invention is to overcome the existing deficiency of dialling the standing grain device, the little problem of standing grain scope is dialled, is stopped up and dials in the leakage when solving harvest corn.
The technical solution adopted for the present invention to solve the technical problems is: a kind of extension type straw shift wheel device comprises worm and gear gearbox, main straw shift wheel, moving tooth, block, cam; An end of worm shaft is connected with corresponding snapping bar in the worm and gear gearbox; The other end is connected with starting taper; The worm and gear gearbox is fixed on the frame; Block and cam also are fixed on the frame, and main straw shift wheel and moving tooth are installed on the worm-wheel shaft that the worm and gear gearbox stretches out, and two straw shift wheels are on the plane of differing heights; In the time need not dialling standing grain, the moving tooth revolution, main straw shift wheel is dialled in milpa between two snapping bars; Arrive when dialling the standing grain scope, moving tooth is turned back to the operating position.
Described extension type straw shift wheel device is installed to main straw shift wheel on the worm-wheel shaft, and moving tooth is installed on the main straw shift wheel through bearing pin, and roller is installed on the moving tooth through bearing pin, because the length difference of worm-wheel shaft is on the plane of differing heights two main straw shift wheels.
Described extension type straw shift wheel device; In the time need not dialling standing grain; Moving tooth is rotation backward under the effect of the reaction force of main body straw shift wheel, milpa and another worm-wheel shaft; Send into milpa two snapping bars between by the effect of main straw shift wheel this moment; Moving tooth forwards the operating position to next time at block and action of cam when the standing grain scope is dialled in arrival, and the cam contour rolling prevents moving tooth hypsokinesis when work to roller in the effect lower edge of the reaction force of the milpa that is struck in dialling the standing grain process, and the while prevents that under the block effect moving tooth from turning forward.
The invention has the beneficial effects as follows; Straw shift wheel is divided into main straw shift wheel and moving tooth two parts, and main straw shift wheel is installed on the rice-pulling shaft, and moving tooth is installed on the main straw shift wheel; Because the length difference of rice-pulling shaft is on the plane of differing heights two main straw shift wheels; So just increased the size of straw shift wheel, simultaneously in the time need not dialling standing grain, moving tooth rotation backward under the effect of the reaction force of main body straw shift wheel, milpa and another rice-pulling shaft; Send into milpa two snapping bars between by the effect of main straw shift wheel this moment, prevents effectively to stop up; Moving tooth forwards the operating position to next time at block and action of cam when the standing grain scope is dialled in arrival, thereby the flexible sphere of action that has increased group standing grain that has realized moving tooth is not so also disturbed corn before leaving simultaneously, effectively improves group standing grain efficient.
