Description
Technical field:
The utility model relates generally to a kind of farm machinery, and particularly a kind of structure is small and exquisite, the superminiature harvesting and tillage machine that weight is lighter.
Background technology:
The farm machinery that is used for farming operation is of a great variety, but is suitable for the Plain in large stretch of straight soil mostly, thereby the agricultural machinery structure generally maximizes.But the southern mountain region of China is many, and now widely used farm machinery can't use in the mountain region, thereby small and exquisite at the mountain region development structure, and the miniature farm machinery that weight is lighter is an inevitable choice.And the rural area take the labour maximum be intensive cultivation to the soil, ploughed in the past and generally used animal power, but be limited to factors such as cost height, use and popularize, therefore can only cut the earth with instruments such as hoes and put in order ground, efficient is extremely low, add that the between twenty and fifty labour in rural area flows to the city, the rural laborer lacks, if re-use this original methods of cultivation, will greatly influence the development of rural productivity.Though there was similar agricultural machinery promoting the use of in the past, really practical is less, is not complex structure, and cost is too high, is exactly the present situation of incompatibility mountainous rural area, and performance is single.Therefore develop a kind of cultivated whole soil that can be used for of suitable mountain area use, the farm machinery that can take into account other purposes again is that reality is needed.
Summary of the invention:
The purpose of this utility model then is to provide a kind of portable superminiature harvesting and tillage machine that can overcome the prior art shortcoming.
For achieving the above object; scheme of the present utility model is: a kind of portable superminiature harvesting and tillage machine; comprise and use an internal combustion engine as power source; to be fixed on as the internal combustion engine of power source on the support; the power output shaft of said internal combustion engine and a speed change system join; speed change system joins by an arrangement of clutch and a transmission system; the power transmission shaft of the end of described transmission system and a level storing joins; the two ends of power transmission shaft respectively have at least one group of cutter tooth; the formed plane of cutter tooth is perpendicular to the ground; the adjusting device of the cutter tooth incision ground degree of depth is arranged, and have protective device and the hand that link to each other with support are held device.
Adopt such scheme, because employed power source power is big and in light weight, it is compact and practical that it ploughs whole separation structure, so complete machine weight is not heavy, is convenient to carrying carry, and has enough functions, thereby finished the purpose of this utility model.
Below in conjunction with diagram and embodiment scheme is described in more detail.
