Abstract

The utility model relates to a hand pushed type automatic harvester which is composed of a machine frame assembly, a circular knife, front and back wheels, a machine cover, etc. A vertical front rotating shaft of the utility model is driven by the front wheel through a gear, a bevel gear and a horizontal front shaft. A circular serrated knife and a crop pulling rod which are arranged on the vertical front rotating shaft are forced by the rotation of the vertical front rotating shaft to rotate. Crops are pulled into the circular serrated knife by the crop pulling rod in order to be cut. A horizontal back shaft is driven by the movement of the back wheels to rotate. A vertical back shaft is driven by the horizontal back shaft through the bevel gear to move. A sprocket follows the back wheels to rotate and drives a chain to move. A crop pushing plate and a crop pushing bracket follow the chain to move annularly along a balancing rail. Cut objects which are sent from the crop pulling rod are forced by the crop pushing plate to be pushed to the outside of a machine body along a crop supporting rod. The utility model has the advantages of small size, light weight and convenient operation. The utility model can be used in paddy fields with complicated landform; the labor intensity is alleviated, and the harvesting speed is increased.

Description

The automatic grain header of hand-push type

The utility model relates to farm implements, the automatic grain header of especially a kind of hand-push type.

The major part of China rural area crops harvesting at present is still based on handwork, and this mode is time-consuming, effort, efficiency are also very low.The combine that mechanization degree is high is popularized gradually and is used, but because of its expense height, use cost is also high, and limited by environmental condition, is difficult to large tracts of land and promotes.

The purpose of this utility model just provides a kind of efficiency height, the automatic grain header of the hand-push type that production cost is low.

The purpose of this utility model is realized by following technical scheme.

The automatic grain header of hand-push type is made of support assembly, circular saw serrated knife, front and back wheel, cover etc., one end of cover is fixed on the support assembly, front-wheel is fixed on the support assembly by axle, horizontal front axle two ends respectively are connected with front-wheel by a pair of big or small meshing gear, be with the umbrella tooth more than two on the horizontal front axle, the lower end of vertical front rotary shaft is provided with the umbrella tooth, horizontal front axle links to each other by the engagement of umbrella tooth with vertical front rotary shaft, be fixed with circular saw serrated knife and upper and lower rice crop grasping rod on the vertical front rotary shaft, overlapped staggered between the circular saw serrated knife; Trailing wheel is fixed on the support assembly by horizontal rear axle, is with two umbrella teeth on the horizontal rear axle, and the lower end of vertical back rotating shaft is provided with the umbrella tooth, and horizontal rear axle links to each other with the logical umbrella tooth engagement of vertical back rotating shaft, and the upper end of vertical back rotating shaft is provided with sprocket wheel, and chain is enclosed within on the sprocket wheel; Also be provided with annular balance track and grain lifting rod, rice crop pushing bracket on the support assembly; Rice crop pushing bracket is placed on the balance track, and the one end is fixed on the chain, and rice crop pushing plate and rice crop pushing bracket flexibly connect.

The automatic grain header of hand-push type of the present utility model drives vertical front rotary shaft by front-wheel by gear, umbrella tooth, horizontal front axle, the rotation of vertical front rotary shaft makes circular saw serrated knife and the rice crop grasping rod rotation on it, rice crop grasping rod is pulled standing grain between the circular saw serrated knife and is cut, and rice crop pushing plate is pushing away the standing grain that cuts off along balance track and grain lifting rod moves and outside the breach kickoff mechanism of right side.

The automatic grain header of hand-push type of the present utility model has that volume is little, in light weight, advantages of simple operation, can be widely used in rice field with a varied topography, both alleviate labour intensity, has accelerated harvesting speed again.

Below in conjunction with accompanying drawing the utility model is elaborated.
