Abstract
The invention discloses a starter of a micro-tillage machine to start a diesel engine of a micro-tillage machine and also start other diesel engines. The starter of the micro-tillage machine is composed of three parts, namely an energy storing mechanism, a one-way clutch and an energy storage controlling mechanism; the starter of the micro-tillage machine is characterized in that an elastic locking device is arranged in the energy storage controlling mechanism. When the energy of a scroll spring is started, a handle is not manually pulled and started, but a ratchet wheel is automatically released by a pawl through the elastic locking device of the energy storage controlling mechanism, and the ratchet wheel is unlocked and the energy of the scroll spring is released to start the engine. The starter is not only convenient to operate but is reliable in working and long in service life.
Description
Technical field
The present invention is a kind of microtilling machine starter, is applicable to the usefulness of the diesel engine starting of microtilling machine, also can be used for the startup of other diesel engine.
Background technique
The application of microtilling machine is more and more extensive, and the problem of the maximum that the microtilling machine that uses now exists is difficulty in starting.Starting method commonly used has two kinds, and a kind of is that stay cord starts, and needs enough power just can draw startup, not only operation effort, and boot disk and stay cord also easily damage.Another kind is manual cranking, be 201120457718.5 disclosed " a kind of air-cooled diesel engine starters " such as the patent No., just belong to the manual cranking device, the shortcoming of this starter is: when discharging whirlpool spring energy, will be with manually pulling starting handle, unidirectional lock dog made auto-lock function open release whirlpool spring energy after starting handle rotated.This unidirectional lock dog pins the structure of whirlpool spring gear, inconvenient operation not only, and when releasing energy, also can produce strong impact, easily damage parts.
Summary of the invention
The purpose of this invention is to provide a kind of microtilling machine starter, when discharging the spiral spring energy, need not manually pull starting handle, but the elastic locking device of energy storage control mechanism can make ratchet automatically decontrol ratchet, make ratchet lose locking, discharge the energy ato unit of spiral spring, this starter is not only easy to operate, and reliable operation, long service life.
Technological scheme of the present invention is as follows: the microtilling machine starter is comprised of stored energy mechanism, overrunning clutch and energy storage control mechanism three parts.Stored energy mechanism is comprised of starter housing (1), gearwheel (2), crank handle interface (3), small gear (4), connection rotating shaft (5) and spiral spring (6) as shown in Figure 1 and Figure 2; Overrunning clutch is comprised of clutch shaft (7), clutch driving plate (11), clutch driven disc (10); The energy storage control mechanism is made of ratchet (8), ratchet (9) and ratchet rotating shaft (12) as shown in Figure 3, Figure 4.It is characterized in that: be provided with elastic locking device in the energy storage control mechanism.Elastic locking device in this example is by hinge (13), spring seat (14), spring (15) and rest pin (16) form, one end of hinge (13) and ratchet (8) are hinged, the other end is screw rod, one end of spring seat (14) is the step seat of support spring, be provided with interior threaded hole, screw with the screw rod of hinge (13), the other end center has groove vertically, groove built-in hold consign (16), spring (15) is sleeved on the spring seat (14), the step seat of one end top spring seat, the supporting of the supported pin of the other end (16).The screw pair of turning joint (13) and spring seat (14), pretightening force that can Regulation spring (15).
During energy storage, the handle of pulling ratchet (8) places ratchet the position of locking ratchet (9), as shown in Figure 3.Crank handle is by crank handle interface (3) rotation pinion (4), driving gearwheel (2) rotates, connection rotating shaft (5) is namely passed through along with gearwheel rotates in the outer end of spiral spring (6), the inner of spiral spring is connected with overrunning clutch axle (7), as shown in Figure 2, clutch shaft (7) is an integral body with clutch driving plate (11), clutch driving plate (11) band dynamic clutch driven disc (10), ratchet (9) is connected as a single entity with clutch driven disc (10) and engine flywheel.Ratchet is subjected to the effect of spiral spring power, rotate toward clockwise direction, when the tooth on the ratchet contacts with ratchet, ratchet is just locked by ratchet, as shown in Figure 3, the moment loading on the ratchet (9) makes ratchet (8) inhour rotation take ratchet rotating shaft (12) as the center of circle to ratchet (8), the countertorque that the elastic force effect of spring (15) produces clockwise rotates ratchet (8), namely locks ratchet.But this locking is by the elastic force effect of spring (15) locking, i.e. elastic locking, core of the present invention that Here it is.Be rotated further crank handle, roll tightly spiral spring (6), moment on the ratchet (9) constantly increases, when the moment on the ratchet can overcome the countertorque of spring (15) generation, ratchet (8) inhour is rotated, turn over after the transition point, the moment that the elastic force of spring (15) produces is reverse, ratchet (8) inhour is rotated, and ratchet is namely decontroled ratchet automatically, and ratchet loses locking, the spiral spring ato unit that releases energy, ratchet is locked into again the position of release, as shown in Figure 4, realizes purpose of the present invention.
