Technical field

The present invention relates to a kind of agriculture and animal husbandry machinery, belong to rotary cultivator technical field, more particularly, to one kind has multiple safety measures Rotary cultivator, be to join with sword protection plate guide wheel to alter the wide horizontal mini-tiller balked during upturned soil type plough disappears.

Background technology

Bread is the staff of life；In farming work, more important work is exactly arable land of ploughing, traditional employment or made with ox For main labour not only high labor intensive, and extremely inefficient.To soil, in particular for hills and mountain area, continually develop and Improve multiple rotary cultivators, to the labour intensity mitigating peasant, improve effect and play a very important role.Rotary cultivator be widely used in by The hobby of people is selected not to carry out operation from the mode walked sometimes from walking sometimes.In recent years, with economical quick Exhibition and social progress, country further enhances farming and animal husbandry work, increases agriculture and animal husbandry equipment and buys subsidy dynamics, and agriculture and animal husbandry is mechanical to be obtained To developing rapidly, rotary cultivator is exactly one of agriculture and animal husbandry machinery.Because rotary cultivator can be widely applied to field, meadow, garden, Vegetable garden, orchard, hot house etc. is ploughed, and ploughs, site preparation, hoes the fields and hack is turned up soil, significantly improve operating efficiency, rotary cultivator is progressively Become rural area, pastoral area, one of agricultural machine machinery that garden management is commonly used, progressively replace original artificial or farm cattle work moulds Formula.But, first, the starting handle of existing rotary cultivator, also referred to as stop working handle, holds and just opens, does not have fault-operation protection measure, When imprudence pressure starts handle, rotary knife will rotate, and do not meet and guarantee safe high request.Secondly, existing rotary cultivator Fender configuration typically just simply mud guard is set above rotary blade, and mud guard is fixed on body, makes With during exist substantially not enough: one is because mud guard only covers the top of rotary blade, stirs up a cloud of dust in rotary tillage machine operation, Dust is big, and poor working environment directly affects the healthy of operator；Two is that sandy soil splash outward, pole in rotary tillage machine operation Easily accidentally injure people；Three is easy foundry loam, and the mud guard due to various rotary cultivators is all made with metallic plate, extruded soil during operation It is mingled with grass roots to be cemented on mud guard, with rotary blade, stronger frictional force occurs solidly, increased power consumption, plus The fast abrasion of rotary blade, the clay that cements on mud guard needs manually be wiped off with shovel, wastes time and energy, affects effect, it is former Therefore one be mud guard be fixing, without being solved using activity or servo-actuated upper mud guard and activity rear mudguard etc. Measure；Mud guard is fixing, has a special case, and it is fixing in rotary tillage process, is only to install to change conveniently, for example in fact With new 200920244006.8, a kind of upper cover board liftable rotary cultivator, its composition includes: rotary cultivator main body, it is characterized in that: Described rotary cultivator main body upper cover plate includes a movable top lid plate connecting by loose-leaf, and described upper cover plate has lock Button；It is fixing during its upper cover plate operation, be activity and servo-actuated upper mud guard and activity during this operation with the present invention The solution such as rear mudguard and left and right protection has the difference of essence.Four is easily to twine grass during rotary tillage, and that is due to various rotary cultivators Mud guard there is no the measure of cutting blade.Moreover, existing rotary cultivator is easy to tilt and overturns, at that rate, no matter rotating or not The rotary blade rotating, has the possibility hindered leg He hinder pin；One of its reason is that rotary cultivator rear portion only has a referred to as drag strut Single bar, it is the drag strut of regulating height, contacts to earth in one end, both can adjust the depth of rotary tillage by adjusting the height of drag strut Degree, plays a kind of effect of the Auxiliary support to rotary cultivator again；Because drag strut is single, that is, a point supports, therefore rotary cultivator Easily crooked；If the single bar improving drag strut is double end bar, or has the double end bar with steamboat, then it is expected to be improved；Also have One reason is cost of transportation；The mud guard of existing rotary cultivator is fixed on body, and volume is big, and in container, box number is limited, It is improved to portable plate or demountable panel it is expected to reduce cost of transportation；If setting its tool wide cut of the outer protection plate of function wave in rotary cultivator to subtract Shake and invigorate and Multipoint Uniform is then safer.The casing of the rotary cultivator of general intermediate transmission has width, casing and rotation Gap must be stayed between blade, therefore intermediate transmission must be had to balk and balk during area is also known as, how inexpensive on tiller simply eliminate Balk, be worldwide hard nut to crack.Because alter before rotary cultivator box body generally to be arranged on ploughed by upturned soil type using, but that being larger Before the rotary cultivator box body that type tractor drives, using effect is notable；And it is very big in the handrail very long lever effect of single hand steered operation When i.e. the direction of advance before rotary cultivator box body and upper and lower yaw direction are waved and are rocked very big, alter upturned soil type plough off and on when and prick Empty lift when lower.And if in the simply easy to manufacture workpiece ploughing shovel etc of lower box mounting structure, effect is simultaneously paid no attention to Think.The elimination of dream peace swing type or inclined-plane eccentric shaft shell type is balked device, and it is complicated and is used for large-scale rotary cultivator, micro computer On be difficult to complete.
