Rotary tiller is a tillage machine with a tractor to complete the plowing, harrowing operations, according to the configuration of its rotary cutter shaft is divided into three types of horizontal axis, vertical axis and tilt type. Because the rotary tiller has a strong ability to break *, plowing after the surface flat and other characteristics, so it has been widely used, but in the specific operation process, to the correct use and maintenance of the rotary tiller, or will not only affect the quality of tillage, reduce the service life of machinery, but also bring threats to their own safety, so today I will briefly talk about the practical operation of the rotary tiller technical points, as follows. Rotary tiller use and maintenance of technical points    

A, the correct use of    

1, start The tiller should be in the lifting state to engage the power, and so the tiller to reach a predetermined speed, the unit can start, preferably at low speed, so as to ensure the quality of work, fine soil, but also to reduce the wear and tear of the machine parts. At the same time to listen to the rotary tiller whether there is a noise or metal knocking sound, observe the broken soil, plowing depth, if there is an abnormality will immediately turn off the engine to ensure personal safety, and then check the work, to troubleshoot before you can continue to work.    

2, turn in the mechanical head turn when the work is prohibited, the tiller should be raised, so that the blade leaves the ground, while reducing the tractor throttle, so as not to damage the blade. Tail wheel and steering clutch to cooperate with each other, slowly, prohibit sharp turns to prevent damage to the parts concerned. In lifting the tiller, the universal joint running tilt angle to less than 30 degrees, the angle is too large will produce impact noise, premature wear or damage.    

3, reversing, transfer In reversing, over the ridge and transfer of plots, the tiller should be lifted to the highest position and cut off the power to avoid damage to the machine. If you want to transfer to a distant place, use the locking device to fix the tiller. Rototiller use and maintenance of technical points    

Second, fault repair    

1, the rototiller load is too large Cause: in the preparation of the land, due to excessive plowing depth, the soil is sticky, too hard, resulting in excessive load on the rototiller.    Elimination method: reduce the plowing depth, reduce the unit forward speed and the speed of the plow blade.   

2, rototiller work jump Cause: hard soil or incorrect blade installation.    Elimination method: reduce the forward speed of the unit and the speed of the plow blade, correct installation of the blade.    

3, the ground after rotary tillage undulation Reason: the unit forward speed and knife shaft speed with improper methods of elimination: appropriate adjustment of the speed between the two.    

4, rotary tiller work with metal knocking sound Cause: transmission chain is too loose with the transmission box body touch; plow blade axis on both sides of the blade, the left support arm or transmission box body deformation after touching each other; blade fixing screws loose.    Elimination method: adjust the transmission chain tension, correction or replacement of severely deformed parts, tighten the loosened screws.    

5, plow blade gearbox noise Cause: installation of foreign objects fall, or bearings, gear teeth damage caused by.    Elimination method: try to remove foreign objects or replace the bearings or gears.    

6, rotary tiller intermittently throws a large * cause: blade bending deformation, blade breakage, loss or serious wear.    Elimination method: correction or replacement of the blade.    

7, rototiller plow shaft does not turn    

Cause: gear or bearing bite; left support arm or transmission box body deformation, plow blade shaft bending deformation; transmission chain broken or plow blade shaft wrapped grass plugging mud serious.    

Removal method: correct, repair or replace the severely deformed and damaged parts, remove the mud entanglement. 

Rototiller use and maintenance of technical points    

Three, the principle of rotary tiller maintenance    

1、Duty maintenance    

(1) check the tightening of the coupling bolts.    

(2) check the curved knife, pins and cotter pins and other wearing parts are not damaged, if there is a defect, it should be replaced in a timely manner.    

(3) check the transmission box, universal joints and bearings for lack of oil, lack of oil, then timely replenishment of oil.    

2、Quarterly maintenance    

(1) thoroughly remove the mud, dust, oil and dirt from the machine.    

(2) replace the lubricant, grease.    

(3) Check whether the blade is excessively worn.    

(4) Check the machine cover, dragging plate, etc. for deformation    

(5) Check the appearance of the machine thoroughly and replenish the paint.    

(6) long-term non-use, wheeled tractor supporting rotary tiller should be placed on the horizontal ground.
