Abstract
A hand-operated reversible plow comprises a plow body and a plow frame. The plow body and the plow frame are connected. The reversible plow further comprises an overturning handle, an overturning mechanism and a suspension bracket. The overturning handle is connected with the overturning mechanism which is connected with the plow frame. The overturning mechanism is driven to move through the rotation of the overturning handle. The plow frame is then overturned. The overturning handle is equipped on the suspension bracket. The overturning mechanism comprises a front sprocket wheel, a rear sprocket wheel and a rotary shaft. The front sprocket wheel is connected with the overturning handle. The front sprocket wheel is connected with the rear sprocket wheel through chains. The rear sprocket wheel is connected with the rotary shaft which is connected with the plow frame. The rotary shaft is connected with the suspension bracket through a bearing and a rotary shaft sleeve. By means of chain transmission, the force required for the overturning of the plow is reduced. Meanwhile, the transmission efficiency is increased. The overturning resistance is decreased through the bearing type overturning. Furthermore, a counterweight iron is adopted by the plow itself. The resistance generated by the deadweight of the plow body is then balanced.

Technical field
The utility model belongs to the pivot plow technical field, particularly a kind of manual pivot plow, and main and fraction horsepower tractor uses.
Background technology
At present, mostly domestic pivot plow present and the fraction horsepower tractor is pneumatic type and fluid pressure type upset.
Because mostly pneumatic pivot plow is small-sized pivot plow, main and fraction horsepower tractor matees and is used for the operation of fritter field, causes easily after the single file work, and the required air pressure that overturns is not enough, is difficult to overturn, and has influenced operating efficiency.
Hydraulic reversing plough (small-sized), because small-sized pivot plow value itself is not high, and pivot plow need be equipped with overturning oil cylinder and reversal valve, has increased cost greatly and has caused the peasant to be difficult to accept price.
And the prior mechanical reversing two-way plow mainly contains link-type and belt-conveying type.Link-type pivot plow working strength at work is big, and reason mainly contains 3 points: 1) do not possess work-saving device in the main switching mechanism.2) reason owing to plow frame causes the centre of draft big apart from the distance at rotating shaft center, has strengthened the required strength of overturning.3) mostly the rotatable parts of existing machinery pivot plow upset are telescopic, have increased the upset resistance.Because the reason of linkage itself, upset work steadily do not cause its safety coefficient not high enough yet.Belt-type pivot plow transmission efficiency loss at work is bigger, skids easily and the phenomenon of the difficulty that occurs overturning.
The utility model content
There is the problem that the upset resistance is big, upset is wasted time and energy in the mechanical type pivot plow in the above-mentioned prior art in order to solve, and the purpose of the utility model is to provide a kind of manual pivot plow, can solve this problem.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of manual pivot plow comprises plough body and plow frame; Plough body is connected with plow frame, and said pivot plow also comprises handle reverse, switching mechanism and hanger bracket, and said handle reverse is connected with said switching mechanism; Said switching mechanism is connected with said plow frame, through the rotation drive switching mechanism motion of handle reverse, thus the upset of realization plow frame; Wherein, said handle reverse is arranged on the said hanger bracket, and said switching mechanism comprises preceding sprocket wheel, back sprocket wheel and rotating shaft; Sprocket wheel is connected with said handle reverse before said, and said preceding sprocket wheel is connected with said back sprocket wheel through chain, and said back sprocket wheel is connected with rotating shaft; Said rotating shaft is connected with said plow frame, and said rotating shaft is connected with said hanger bracket through bearing, rotating shaft cover.
Preferably, said hanger bracket two ends are respectively equipped with left limit plate and the right limit plate that is used to limit said plow frame upset degree.
Preferably, said manual pivot plow also comprises balance weight iron, and balance weight iron is arranged on an end of said plow frame.
The beneficial effect of the utility model: reduced this power required in switching process of plough through chain drive in the utility model, improved transmission efficiency simultaneously.Through the bearing-type upset, reduce the upset resistance.Itself adopts balance weight iron, makes the resistance that produces because of the plough body deadweight obtain balance.
