Abstract
The utility model provides a speed changing box provided with a safety clutch and used for a maize harvesting machine. The speed changing box comprises a box body, a power input shaft, a first power output shaft and a second power output shaft, wherein the power input shaft, the first power output shaft and the second power output shaft are arranged on the box body; two gears are respectively arranged on the first power output shaft and the second power output shaft; and teeth of the two gears are meshed with one another. The speed changing box is characterized in that the safety clutch, an intermediate shaft and a third power output shaft are additionally arranged on the speed changing box; the power input shaft, the intermediate shaft and the three power output shafts are parallel to one another; the safety clutch is fixedly arranged on the power input shaft through a key; a shell of the safety clutch is in the shape of an outer gear ring; two gears are respectively arranged on the intermediate shaft and the third power output shaft; the shell of the safety clutch is respectively meshed with the gear of the second power output shaft and the gear of the intermediate shaft; and the gear of the intermediate shaft is also meshed with the gear of the third power output shaft. The speed changing box is compact in structure, the three power output shafts are integrated to synchronously output power, key components are protected, and the speed changing box can automatically reset after being overloaded.
Description
Technical field
The utility model provides a kind of maize harvesting machine with the gearbox that overload clutch is housed, and belongs to agricultural machinery technological field.
Background technology
At present, the transfer gear box in the domestic existing maize harvesting machine is not installed overload clutch more, because the farmland operation circumstance complication if ceding of Taiwan obstruction or load are excessive, is prone to cause shredder bar fracture or gear overload to fracture; Or friction-type safety clutch is housed, and lean on the frictional force driving torque of friction plate, when often transshipping, friction plate is prone to heating and lost efficacy, and influences the safety of facility; Or overload shearing clutch is housed, and that leans on pin cuts off the interruption transmission, and pin is had no progeny; Change loaded down with trivial detailsly, make troubles to agricultural production, and because the accumulation of fatigue strength; The intensity of pin can reduce with the increase of working time, increases the cutting machine meeting, thereby delays the best farming time.
The utility model content
The purpose of the utility model is to provide a kind of can overcome above-mentioned defective, security reliability height, compact conformation, can when overload, also can use the gearbox that overload clutch is housed by automatically reset maize harvesting machine by the protection vitals.Its technical scheme is:
A kind of maize harvesting machine is with the gearbox that overload clutch is housed; Comprise casing and be arranged on power input shaft, first power take-off and second power take-off on the casing; Wherein be equipped with a gear on first power take-off and second power take-off, both tooth engagements is characterized in that: set up overload clutch, jackshaft and the 3rd power take-off; And power input shaft, jackshaft and three power take-offs are parallel to each other; Wherein overload clutch is fixedly mounted on the power input shaft through key, and its shell is the external tooth round, is equipped with a gear on jackshaft and the 3rd power take-off; The shell of overload clutch respectively with second power take-off, jackshaft on gears engaged, the gear on the jackshaft also with the 3rd power take-off on gears engaged.
Described maize harvesting machine is with the gearbox that overload clutch is housed, and overload clutch adopts the peg type overload clutch.
Described maize harvesting machine is with the gearbox that overload clutch is housed, second power take-off be positioned at power input shaft directly over.
Its operation principle is: under the normal operating conditions; Power imports gearbox into via power input shaft; Overload clutch rotates; And then drive the gear be arranged on jackshaft, first power take-off, second power take-off and the 3rd power take-off through shell and rotate, reach three power take-offs and export synchronously.When the facility load was excessive, overload clutch was thrown off, and this moment, power can not be delivered on jackshaft, first power take-off, second power take-off and the 3rd power take-off of gearbox, and the facility vitals is played the safeguard protection effect; After the facility load descended, overload clutch combined, and power is able to continuity, and facility continue operation.
The utility model compared with prior art, its advantage is:
1, this gearbox designs is compact, integrated three synchronous outputting powers of power take-off;
2, the use of overload clutch, when gearbox transshipped, vitals was effectively protected, and can automatically reset after the overload, and facility continue operation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, casing 2, power input shaft 3, first power take-off 4, second power take-off 5, gear 6, overload clutch 7, jackshaft 8, the 3rd power take-off 9, shell
Embodiment
In the embodiment shown in fig. 1: casing 1 is provided with power input shaft parallel to each other 2, first power take-off 3, second power take-off 4, jackshaft 7 and the 3rd power take-off 8; And second power take-off 4 be positioned at power input shaft 2 directly over; Except that power input shaft 2, be equipped with a gear 5 on other axle.Peg type overload clutch 6 is fixedly mounted on the power input shaft 2 through key, and the shell 9 of peg type overload clutch 6 is the external tooth round.The shell 9 of overload clutch 6 respectively with second power take-off 4, jackshaft 7 on gear 5 engagements; Gear 5 engagements of second power take-off 4 and first power take-off 3, the gear 5 on the jackshaft 7 through being provided with separately also with the 3rd power take-off 8 on gear 5 engagements.
