Technical field

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

Background technology

Bread is the staff of life；In farming is worked, comparatively important work is ploughed arable lands exactly, traditional employment or with Niu Zuowei main labour not only labor intensity greatly, and extremely inefficient.To soil, in particular for hills and mountain area, continually develop and improve multiple rotary cultivator, to the labor intensity alleviating peasant, improve effect and play a very important role.Rotary cultivator be widely used in by the hobby of people selected sometimes from walk sometimes from the mode do not walked to carry out operation.In recent years, along with economic fast development and social progress, country further enhances farming and animal husbandry work, increases agriculture and animal husbandry facility and buys subsidy dynamics, and agriculture and animal husbandry machinery is developed rapidly, and rotary cultivator is exactly the one in agriculture and animal husbandry machinery.Owing to rotary cultivator can be widely applied to field, meadow, garden, vegetable garden, orchard, hot houses etc. are ploughed, and plough, wholely, hoe the fields and hack is turned up soil, significantly improving work efficiency, rotary cultivator progressively becomes rural area, pastoral area, one of agricultural machine machinery that garden management is conventional, progressively replaces original use manually or the work pattern of farm cattle.But, first, the starting handle of existing rotary cultivator, also referred to as flame-out handle, hold and just open, it does not have fault-operation protection measure, when imprudence pressure starts handle, rotation cutter will rotate, and do not meet and guarantee safe high request.Secondly, the fender configuration of existing rotary cultivator is typically just provided above mud guard at rotary blade simply, and mud guard is fixed on body, in use exist substantially not enough: one is the top only covering rotary blade due to mud guard, stir up a cloud of dust when rotary cultivator operation, dust is big, and poor working environment directly affects the healthy of operator；Two is that sandy soil splash outward when rotary cultivator operation, very easily accidentally injures people；Three is easy foundry loam, owing to the mud guard of various rotary cultivators is all made 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 abrasion 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, without the solution such as rear mudguard of employing activity or servo-actuated upper mud guard and activity；Mud guard is fixing, there is a special case, it is fixing when rotary tillage process, it is only install to change conveniently, such as utility model 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 connected by loose-leaf, and described upper cover plate has snap close；It is fixing during its upper cover plate operation, is that the solution such as rear mudguard and left and right protection of movable and servo-actuated upper mud guard and activity has essential difference during this operation with the present invention.Four easily twine grass when being rotary tillage, and that is owing to the mud guard of various rotary cultivators does not have the measure of cutting blade.Moreover, existing rotary cultivator is prone to tilt and overturning, at that rate, rotary blade that is that no matter rotate or that do not rotate, there is the possibility hindered lower limb He hinder foot；One of its reason is that rotary cultivator 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, play again a kind of auxiliary supporting role to rotary cultivator；Because drag strut is single, namely a point supports, therefore rotary cultivator is 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 having a 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, is improved to portable plate or demountable panel, it is expected to reduce cost of transportation；If setting function wave its tool wide cut vibration damping of outer protection plate at rotary cultivator and invigorating and Multipoint Uniform, safer.The casing of the rotary cultivator 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 tiller inexpensive eliminate simply in balk, be worldwide hard nut to crack.Use because altering before upturned soil type plough to be generally arranged on rotary cultivator box body, but that is that result of use is just notable before the rotary cultivator box body that relatively large tractor drives；And when single hand steered operation, handrail very long lever effect is very big, namely direction of advance before rotary cultivator box body and up and down yaw direction wave when rocking very big, alter upturned soil type and plough off and on, under Shi Erzha, time and sky is lifted, with not becoming.And if at the workpiece of lower box mounting structure plough shovel etc simply easy to manufacture, 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 is used for large-scale rotary cultivator, and micro computer has been difficult to.Existing driving machine many employings electromotor, and multiple-purpose diesel motor or gasoline engine.Fuel used by gasoline engine is gasoline；Gasoline and air is made to be initially formed combustion mixture before entering cylinder with air filter 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, compression is also combustion mixture, owing to gasoline and air form combustion mixture, the phenomenon that mist shape can only be become in moment and cause part fuel oil to fail all the time to burn completely after entering cylinder because of excessive fuel oil, therefore oil consumption and exhaust pollution environment.And its atomizing effect of diesel engine is no exception.Noise abatement is dropped the way of certain hope of row and is adopted combustion gas exactly.

Summary of the invention

The present invention relates to a kind of agriculture and animal husbandry machinery, belong to rotary cultivator technical field, it it is the rotary cultivator of the electromotor with fuel gas tank improved, it includes the rotary cultivator that drives with the four-stroke engine of miniature propane fuel tank and joins with sword protection plate guide wheel and alter during upturned soil type plough disappears the wide horizontal mini-tiller balked, it is also related to a kind of rotary cultivator having multiple safety measures lose, namely has the servo-actuated backplate retaining frame of safety and double; two dynamic security switchs and the rotary cultivator of safe resistance fork wheel.Adopt guide wheel (p9) and alter the combination of upturned soil type plough (p104) and be used as application front jocket wheel and join the new of plough and eliminate the middle method balked；Described guide wheel (p9) and the described combination altering upturned soil type plough (p104) are located on the axis of direction of advance of rotary cultivator；Guiding the direction of advance making miniature rotary cultivator and upper and lower yaw direction to tend to be steady with guide wheel, the thing followed is to adopt upturned soil type of the altering plough of double-vane shovel, buries steadily, and mouldboard laterally digs angle relatively greatly, increases button upturned soil ability, reduces blocking；Elimination is balked, grading, it does not have ditch ridge, adopts guide wheel and alter the combination of upturned soil type plough and be used as application front jocket wheel and join the method balked in the middle of the eliminating of plough on miniature rotary cultivator, and this belongs to pioneering.In order to continually develop and improve rotary cultivator, promote safety, improve effect, the special open present invention.Existing driving machine many employings electromotor, and multiple-purpose diesel motor or gasoline engine.Fuel used by gasoline engine is gasoline；Gasoline and air is made to be initially formed combustion mixture before entering cylinder with air filter 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, compression is also combustion mixture, owing to gasoline and air form combustion mixture, the phenomenon that mist shape can only be become in moment and cause part fuel oil to fail all the time to burn completely after entering cylinder because of excessive fuel oil, therefore oil consumption and exhaust pollution environment.And its atomizing effect of diesel engine is no exception.Noise abatement is dropped the way of certain hope of row and is adopted combustion gas exactly.Combustion gas is gaseous state under room temperature normality, enters electromotor in a gaseous form, can realize more uniform mixing with air, makes burning more abundant, it is expected to reduce the discharge capacity of carbon monoxide and hydrocarbon, make particulate emissions improve.The flame stability of combustion gas is relatively low, and in-cylinder combustion temperature declines, and makes the discharge of oxynitride reduce to some extent.It is low when using gasoline that combustion gas makes the toxicity of noxious emission compare.Discharge seldom has the composition of harm containing aromatic hydrocarbon etc..Owing to combustion gas does not form oil film at admission line wall, unlike gasoline, also to carry out cold conditions enriching, 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 harmful gas will not because of the reformation of electromotor 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 air-fuel of combustion gas is easier to adjust, and burns more stable, and operating is relatively steady, can reduce the noise of complete machine.Gasoline engine changing into fuel gas 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, makes the charging efficiency of electromotor increase, and the efficiency of cycle improves；And combustion gas does not have similar evaporation process in air inlet pipe with cylinder, engine power is caused to decline.The electromotor designed exclusively for combustion gas be just expected on realization theory gas engine produce higher power than petrol engine, because the Unit Weight of combustion gas is higher than the weight that gasoline can be provided by by 8%.This improves and mainly adopts the general fuel gas tank easily changed.

Usefulness: the rotary cultivator of the electromotor with fuel gas tank of improvement, it includes the engine-driven rotary cultivator with miniature propane fuel tank and joining with sword protection plate guide wheel and alters during upturned soil type plough disappears the wide horizontal mini-tiller balked, and is also related to a kind of rotary cultivator having multiple safety measures.Safe resistance fork wheel is not easily crooked and is prone to guiding, and moving apron has demountable panel；Have outer protection plate assembly to further increase safety, and because it adopts the outer protection plate of function wave, its compressive strain and upspring, the effect of tool wide cut vibration damping multi-spot balancing；Join with sword protection plate guide wheel and alter during upturned soil type plough tool disappears the effect balked.Mining combustion gas drops in noise abatement.Reduce the discharge capacity of carbon monoxide and hydrocarbon, make particulate emissions improve, make the discharge of oxynitride reduce to some extent.It is low when using gasoline that combustion gas makes the toxicity of noxious emission compare.Combustion gas discharge 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.
