Problems solved by technology
Since the paddy field is only tilled by a rotary tiller, it is difficult to meet the operation requirements of a rice transplanter with a surface unevenness within the range of 1-2cm, so it is easy to cause defects such as missed transplanting and drifting during the process of machine transplanting, which restricts machine transplanting.

Embodiment Construction
[0012] Such as figure 1 , 2 As shown, a portable paddy field is composed of engine 1, handrail 2, centrifugal clutch 3, transmission shaft 4, transmission shaft sheath 5, worm 6, worm wheel 7, left roller 9, right roller 8, etc., left, The right roll consists of a drum and a deflector welded on the drum respectively. The engine 1 adopts a gasoline engine with a two-stroke power of 0.8-1.5kw. The centrifugal clutch 3 is connected to the crankshaft of the gasoline engine and connected to the transmission shaft 4. The lower end of the transmission shaft 4 is connected to the worm 6 through a spline, and the worm meshes with the worm wheel 7. The right roll is respectively connected on the left and right shaft heads of the worm gear shaft and positioned by pins.
[0013] The cylinder diameter of above-mentioned left and right roll 9,8 is 180mm, and length is 900mm, and the deflector height on it is 66mm, and length is 314mm. The cylinder lengths of the left and right rollers 9 ...

The invention discloses a portable paddy field harrow. The portable paddy field harrow is composed of a handrail (2), an engine (2) fixedly installed on the handrail (1), a centrifugal clutch (3) with the two ends connected with an engine crankshaft and a transmission shaft (4) respectively and a roller formed by a roller body and flow guide plates welded to the roller body. A worm (6) meshed with a worm gear (7) is connected to the lower end of the transmission shaft (4). A left roller (9) and a right roller (8) are connected to the left end and the right end of a worm gear shaft respectively. The engine drives the left roller and the right roller through the worm gear and the worm, paddy-field mud generates certain flowing under the effect of the flow guide plates arranged in a leftward helical line or rightward helical line mode accordingly, the mud protruding out of the surface of paddy fields flows into the sunken portions of the surface, the unevenness of the surface of the paddy fields is controlled within the range from 1 cm to 2 cm accordingly, and the paddy-field surface evenness required by operation of a rice transplanter is met; the portable paddy field harrow has the advantages of being simple in structure, reliable in use and convenient to carry.
Description
technical field [0001] The invention relates to an agricultural machine, in particular to a portable rice paddy plant. Background technique [0002] At present, although my country's rice transplanter technology is relatively mature, the machine transplanting rate of rice transplanters is still low, only 20-30%. There are many factors that cause this result, among which the rice transplanter's requirement for the flatness of the paddy field surface is one of the important reasons that affect the use of the rice transplanter. Since the paddy field is only rotary tilled by the rotary tiller, it is difficult to meet the operation requirements of the rice transplanter with the unevenness of the surface within the range of 1-2cm, so it is easy to cause defects such as missed transplanting and drifting during the machine transplanting process, which restricts the machine transplanter. Promotion and use of technology. Contents of the invention [0003] The object of the present...
