Description

The rotovator of the engine with fuel gas tank improved

Technical field

The present invention relates to a kind of agriculture and animal husbandry machinery, belong to rotovator technical field, it is the rotovator of the engine with fuel gas tank improved, it comprises rotovator that the four-stroke engine with miniature propane fuel tank drives and joins the wide horizontal mini-tiller of altering during upturned soil type plough disappears and balking with sword protection plate guide wheel, also relates to a kind of rotovator having multiple safety measures.

Background technology

Bread is the staff of life; In farming work, the work of outbalance is exactly arable lands of ploughing, traditional employment or with the main labour of Niu Zuowei not only labour intensity greatly, and efficiency is extremely low.To soil, especially for hills and mountain area, continually develop and improve multiple rotovator, to the labour intensity alleviating peasant, improve effect and play a very important role.The mode that rotovator is widely used in sometimes certainly not walking by sometimes certainly walking selected by the hobby of people is to carry out operation.In recent years, along with fast development and the social progress of economy, country further enhances farming and animal husbandry work, and increase agriculture and animal husbandry facility and buy subsidy dynamics, agriculture and animal husbandry machinery is developed rapidly, and rotovator is exactly the one in agriculture and animal husbandry machinery.Because rotovator can be widely used in field, meadow, garden, vegetable garden, orchard, the arable lands such as plastic tunnel, plough, wholely, hoe the fields and hack upturned soil, significantly improve operating efficiency, rotovator progressively becomes rural area, pastoral area, one of agricultural machine machinery that garden management is conventional, progressively replaces the work pattern of the artificial or farm cattle of original use.But first, the starting handle of existing rotovator, also referred to as flame-out handle, holds and just open, and does not have fault-operation protection measure, when handle is started in careless pressure, revolving cutter will rotate, and does not meet and guarantee safe high request.Secondly, the fender configuration of existing rotovator generally just arranges mud guard simply above rotary blade, and mud guard is fixed on body, in use exist obviously not enough: one is because mud guard only covers the top of rotary blade, stir up a cloud of dust when rotovator operation, dust is large, and poor working environment, directly affects the healthy of operator; Two is that sandy soil splash outward, very easily accidentally injure people when rotovator operation; Three is easy foundry loams, mud guard due to various rotovator is all make with metallic plate, during operation, extruded soil is mingled with grass roots and is cemented on mud guard, there is stronger frictional force with rotary blade solidly, add power consumption, accelerate the wearing and tearing of rotary blade, the clay that cements on mud guard needs artificial shovel to wipe off, waste time and energy, affect effect, one of its reason is mud guard is fixing, and not employing activity or the solution such as rear mudguard of servo-actuated upper mud guard and activity; Mud guard is fixing, there is a special case, it is fixing when rotary tillage process, only install to change conveniently, such as utility model 200920244006.8, a kind of upper cover board liftable rotary cultivator, its composition comprises: rotovator main body, it is characterized in that: described rotovator main body upper cover plate comprises a movable top lid plate connected by loose-leaf, and described upper cover plate has snap close; Fixing during its upper cover plate operation, when this and operation of the present invention be movable with servo-actuated upper mud guard and the solution such as the rear mudguard of activity and left and right protection have the difference of essence.Four easily twine grass when being rotary tillages, and that is because the mud guard of various rotovator does not have the measure of cutting blade.Moreover existing rotovator is easy to and overturning, and at that rate, rotary blade that is that no matter rotate or that do not rotate, has the possibility of hindering leg He hindering pin; One of its reason is that rotovator rear portion only has a single bar being called drag strut, and it is the drag strut of regulating height, contacts to earth in one end, both can adjust the degree of depth of rotary tillage by regulating the height of drag strut, playing again a kind of supplemental support effect to rotovator; Because drag strut is single, namely a point supports, therefore rotovator is easily crooked; If the single bar improving drag strut is double end bar, or there is the double end bar of band steamboat, be then expected to be improved; A reason is also had to be cost of transportation; The mud guard of existing rotovator is fixed on body, and volume is large, and in container, box number is limited, is improved to portable plate or demountable panel, is expected to reduce cost of transportation; If establish outer its tool wide cut vibration damping of protection plate of function wave at rotovator and invigorate and Multipoint Uniform, safer.The casing of the rotovator of general intermediate transmission has width, must stay gap between casing and rotating blade, thus must have intermediate transmission balk district also known as in balk, how on mini-size tillage machine inexpensive eliminate simply in balk, be worldwide hard nut to crack.Use because alter before upturned soil type plough will be arranged on rotary cultivator box body usually, but that is that result of use is just remarkable before the rotary cultivator box body that relatively large tractor drives; And when single hand steered operation, handrail very long lever effect is very large, when the direction of advance namely before rotary cultivator box body and up and down yaw direction are waved and rocked very large, alter upturned soil type plough off and on, under Shi Erzha, time and sky is lifted, with not becoming.And if lower box mounting structure simply easy to manufacture plough shovel and so on workpiece, effect is unsatisfactory.Dream peace swing type or the elimination of inclined-plane eccentric shaft shell type are balked device, and it is complicated and be used for large-scale rotovator, and microcomputer has been difficult to.Existing driving machine many employings engine, and multiple-purpose diesel motor or gasoline engine.Gasoline engine fuel used is gasoline; Gasoline and air is made first to form combustion mixture before entering cylinder with air cleaner and carburetor etc.; By the quick-fried row of four-stroke entrance pressure, combustion mixture enters in cylinder and is compressed, close to compressing at the end ignition and expansion working, what gasoline engine entered cylinder is combustion mixture, what compress is also combustion mixture, because gasoline and air form combustion mixture, because of excessive fuel oil enter cylinder after can only become mist vaporous in moment and cause the phenomenon that part fuel oil fails to burn completely all the time, therefore oil consumption and exhaust pollution environment.And its atomizing effect of diesel engine is no exception.Certain hope that row falls in noise abatement is exactly adopt combustion gas on the way.

Summary of the invention

The present invention relates to a kind of agriculture and animal husbandry machinery, belong to rotovator technical field, it is the rotovator of the engine with fuel gas tank improved, it comprises rotovator that the four-stroke engine with miniature propane fuel tank drives and joins the wide horizontal mini-tiller of altering during upturned soil type plough disappears and balking with sword protection plate guide wheel, also relating to a kind ofly has the rotovator of multiple safety measures to lose, and namely has the rotovator of the servo-actuated backplate retaining frame of safety and two dynamic security switchs and safe resistance fork wheel.The combination adopting guide wheel (p9) and alter upturned soil type plough (p104) is used as applying the method balked in new elimination centre that front jocket wheel joins plough; Described guide wheel (p9) and described combination of altering upturned soil type plough (p104) are located on the axis of the direction of advance of rotovator; Guiding with guide wheel makes the direction of advance of miniature rotary cultivator and upper and lower yaw direction tend to be steady, and the thing followed is upturned soil type of the altering plough adopting double-vane shovel, buries steadily, and mouldboard side direction digs angle comparatively greatly, increases button upturned soil ability, reduces blocking; Elimination is balked, grading, does not have ditch ridge, and miniature rotary cultivator adopts guide wheel and the combination of altering upturned soil type plough are used as applying front jocket wheel and join the method for balking in the middle of the elimination of plough, this belongs to initiates.In order to continually develop and improve rotovator, promote safety, improve effect, special open the present invention.Existing driving machine many employings engine, and multiple-purpose diesel motor or gasoline engine.Gasoline engine fuel used is gasoline; Gasoline and air is made first to form combustion mixture before entering cylinder with air cleaner and carburetor etc.; By the quick-fried row of four-stroke entrance pressure, combustion mixture enters in cylinder and is compressed, close to compressing at the end ignition and expansion working, what gasoline engine entered cylinder is combustion mixture, what compress is also combustion mixture, because gasoline and air form combustion mixture, because of excessive fuel oil enter cylinder after can only become mist vaporous in moment and cause the phenomenon that part fuel oil fails to burn completely all the time, therefore oil consumption and exhaust pollution environment.And its atomizing effect of diesel engine is no exception.Certain hope that row falls in noise abatement is exactly adopt combustion gas on the way.Combustion gas is gaseous state under normal temperature normality, enters engine in a gaseous form, can realize mixing more uniformly with air, makes burning more abundant, is expected the discharge capacity reducing carbon monoxide and hydrocarbon, particulate emissions is improved.The flame stability of combustion gas is lower, and in-cylinder combustion temperature declines, and the discharge of oxynitrides is reduced to some extent.It is low when using gasoline that combustion gas makes the toxicity of noxious emission compare.Seldom there is the composition of harm containing aromatic hydrocarbon etc. in discharge.Because combustion gas does not form oil film at admission line wall, also cold conditions enriching will be carried out unlike gasoline, therefore the discharge in starting 40 seconds and in warming-up is better than gasoline engine.The discharge stability of combustion gas is high, and the discharge of pernicious gas can not because of the reformation of engine and aging and increase.The evaporation of seal aspect and Leakage are also less.The octane number of combustion gas is higher.The burning-point of combustion gas is higher than gasoline, and boundary of catching fire is wider than gasoline, compares gasoline safety.The sky combustion of combustion gas more easily adjusts, and burns more stable, and running is comparatively steady, can reduce the noise of complete machine.Gasoline engine is changed into fuel gas to drive, power can decline.Gasoline carburation by evaporation in air inlet pipe and cylinder can absorb certain heat, reduces intake air temperature, improves density of the induced air, the charging efficiency of engine is increased, and the efficiency of cycle improves; And combustion gas does not have similar evaporation process in air inlet pipe and cylinder, engine power is caused to decline.Be specially the power that gas engine combustion gas and the engine that designs just are expected on realization theory is higher than petrol engine generation, the weight that the Unit Weight because of combustion gas can provide than gasoline is high by 8%.This improvement mainly adopts the general fuel gas tank easily changed.

Usefulness: the rotovator of the engine with fuel gas tank of improvement, it comprise with miniature propane fuel tank engine-driven rotovator and with sword protection plate guide wheel join alter upturned soil type plough disappear in the wide horizontal mini-tiller of balking, also relate to a kind of rotovator having multiple safety measures.Safe resistance fork is taken turns not easily crooked and is easy to guiding, and moving apron has demountable panel; There is outer protection plate assembly to further increase safety, and adopt the outer protection plate of function wave because of it, its compressive strain and upspringing, the effect of tool wide cut vibration damping multi-spot balancing; The effect of altering during upturned soil type plough tool disappears and balking is joined with sword protection plate guide wheel.Mining combustion gas falls in noise abatement.Reduce the discharge capacity of carbon monoxide and hydrocarbon, particulate emissions is improved, the discharge of oxynitrides is reduced to some extent.It is low when using gasoline that combustion gas makes the toxicity of noxious emission compare.The discharge of combustion gas in starting 40 seconds and in warming-up is better than gasoline engine, and complete machine safety is good.Fuel gas tank is easily changed.
