Description

The supporting structure of tail-operated pedal-front-mounted type walking tractor

Affiliated technical field:

The utility model relates to a kind of auxiliary component structure of on tail-operated pedal-front-mounted type walking tractor, using.

Background technology:

Present known hand tractor seat sub-assembly, tail pulley structure front do not have pedal folding connecting shaft and front positioning type pedal, just can meet the demands so this tractor must have with former different auxiliary component, and not so this machine will be difficult to use.

Summary of the invention:

In order to overcome the difficult problem that existing hand tractor parts are difficult on this machine, using; The utility model provides some parts to comprise: novel rotovator body structure; Punching press or welding, pedal weldment, the novel farm implements weldment of novel handgrip weldment, novel punching press tail-wheel fork structure, the parallelogram farm implements lower link of reinforcement.

The utility model solves the technical scheme that its technical problem adopted: this tractor driver is being pull-up, in order to change the pull-up handgrip into, this tractor driver in the connection steel plate be that square or rectangular stretches out downwards a lot so that the connection bolt is avoided the just elevating arc after handgrip is turned back axle; And handgrip is turned back axle for being fixedly welded on fan tooth rotating shaft center, on the head jack, latch is arranged, and elevating arc adopts the similar of knockdown and workers and peasants' one 81 types, but its latch is closeer, more to be reached more than 7 teeth; Can be casting or steel plate machine-shaping, and novel pedal structure is to weld a stamping forming pedal on the steel pipe head that stretches out to the left and right on the former T type pedal weldment, its structure be that a block plate is struck out the tennis racket shape, has the bag shape protruding on it; On a deep trouth is arranged, deep trouth is used to snap in steel pipe, plays welding and location, is adopting round steel to curve under the situation of racket shape pedal; Horizontal or straight steel bar in the welding in the frame of racket shape pedal, with the effect of the contact-making surface that increases pedal and pin, the structure of this tail wheel fork is that tail-gear spindle penetrates one and saves in the square tube, is welded into T type structure; Two blocks of caudal furca steel plates in square tube both sides welding, its structure is up big and down small steel plate, one side on its limit to folding the angle steel limit, the angle steel limit that folds also is up big and down small; Play reinforcement, all have circular arc to handle certainly on it, can reduce steel plate caudal furca thickness like this and save material, being similar on the screw head on the parallelogram farm implements lower link on the workers and peasants-12 at this machine has u shaped connector; There is screw to be slidingly connected in the middle of the joint and between the screw rod, welds thickening or be employed in the mode that the screw hole place is widened with another block plate in the middle of the u shaped connector, can improve lower link intensity like this, novel farm implements weldment is arranged on this machine to carry bigger pulling force; Be characterized on the back of single hole grooved farm implements Connection Block, welding plow standard or rake post, plow standard or rake post are to dig a right angle breach on pipe, square tube or the oblate tube head, the farm implements Connection Block is snapped in breach be welded to connect, and the bonding strength of plow harrow is strengthened greatly; Connecting structures such as plough, rake, water Dual-purpose harrow morning through bolt below the minimizing distortion, pipe, square tube or oblate pipe, be diplopore when connecting plough, and plow standard has certain camber also to flatten; Being used in this box body that some central box formula rotovators can not packing list be beneficial to wear screw rod, and the rake post be to bore the hole on the pipe, because must have new structure on this casing, to use; This machine rotovator casing is divided into left and right sides two halves box-like structure, and casing can be casting or punch forming structure, and punching press welding combining structure, and on the two halves formula casing first overhanging bearing top circle is all arranged; There is the bearing position casing and shaft connection place, and the casing two halves are linked to be an integral body with bolt, and first in the casing is speed change and clutch shaft, is the circular shaft that half spline structure is arranged; The power input shaft that this casing of ining succession stretches out outward has dog clutch, shift fork commonly used on the rotovator on first, with and coaxial minor sprocket or pinion, the rotovator lower box is a rotary tiller shaft; The wheeled sprocket wheel of big driving cog is arranged on it, is small one and large one two duplicate gears or sprocket wheel on middle one, to form two-stage gear or chain deceleration transmission, in having the gear of speed changing function; The parallel connection of the jaw clutch of its uppermost power input shaft small one and large one duplicate gear, supporting bidentate wheel and small transmission gear or minor sprocket are arranged on the jackshaft, the gear wheel of back or sprocket wheel and rotary tiller shaft are coaxial again; The transmission that just links to each other of pinion or minor sprocket with coaxial hinge wheel of rotary tiller shaft or gear wheel, certain simple type that two chain drives of direct employing are also arranged, the transmission that links to each other of the hinge wheel on the cutter shaft below the minor sprocket on first and the casing just; Also strainer should be arranged, with bolt two halves formula casing is linked to be an integral body around the casing, the bearing position is arranged on the casing.

The beneficial effect of the utility model is: can make this tractor put the machine of ploughing and a part of parts, and rational in infrastructure, better accomplish the action of tractor.
