Embodiment 1

[0039] When rotary tillage and weeding are required, before starting the tiller, the operating lever 16 is moved to the left side of the knife shaft 2, and the shift fork 14 is driven to the knife shaft 2 by the shift fork connecting rod 15 of the clutch, shifting and reversing device. Swipe to the right of the . The shift fork 14 slides to the right side of the cutter shaft 2 to drive the dial sleeve 13 to slide synchronously to the right side of the cutter shaft 2, so that the four trapezoidal convex teeth on the right end surface of the dial sleeve 13 are inserted into the four trapezoidal teeth on the inner end surface of the right spiral bevel gear 9. Trapezoidal concave keyway.

[0040] After starting the machine, the power is input from the longitudinal helical gear shaft 7, and the helical gear shaft 7 is always meshed with the left helical bevel gear 5 and the right helical bevel gear 9 through the helical bevel gear 17, and the left helical bevel gear 5 and the right...

Embodiment 2

[0042] When ditching is required, before starting the tiller, install the ditching knife group on the knife shaft 2 through the pin shaft 22, move the operating lever 16 to the right side of the knife shaft 2, and drive it through the fork connecting rod 15 Shift fork 14 slides to the left side of cutter shaft 2. The shift fork 14 slides to the left side of the cutter shaft 2 and drives the dial sleeve 13 to slide to the left, so that four trapezoidal protruding teeth on the left end face of the dial sleeve 13 are inserted into four trapezoidal grooves on the inner end face of the left spiral bevel gear 5 .

[0043] After starting the machine, power is input from the vertical helical gear shaft 7, and its one end helical bevel gear 17 is always engaged with the left helical bevel gear 5 and the right helical bevel gear 9, and both rotate simultaneously. The four protruding teeth on the right end surface of the dial sleeve 13 are in a disengaged state from the four grooves on t...

Embodiment 3

[0046] When it is necessary to climb slopes, climb mountains, or move between plots, before starting the tiller, set the operating lever 16 to the middle position, and drive the shift fork connecting rod 15 and the shift fork 14 to slide to the middle position, and the shift fork 14 drives the shifter The sleeve 13 is slid to the middle position. After starting the machine, power is input from the vertical helical gear shaft 7, and the helical bevel gear 17 at one end meshes with the left helical bevel gear 5 and the right helical bevel gear 9, driving both to rotate simultaneously.

[0047] Because shift fork 14 is in the middle position, four protruding teeth of its left and right end surfaces are in disengagement state simultaneously with left helical bevel gear 5 and right helical bevel gear 9, power can't be transmitted to shift fork 13, and cutter shaft 2 also loses power thereupon. Now the road wheel 23 rotates and the cutter shaft 2 does not rotate, so that climbing, m...

Abstract

The invention belongs to agricultural mechanical equipment and relates to a power transmission device for a mini-tiller, in particular to a full-gear transmission-type power transmission device whichis provided with a clutch gear shift and reversing device and used for the mini-tiller. The device comprises a power input mechanism, a power output mechanism, the clutch gear shift and reversing device between the power input mechanism and the power output mechanism and walking wheels; the walking wheels are connected with the power input mechanism through a walking wheel gearbox. According to the power transmission device for the mini-tiller, under the situation that the rotation directions of the walking wheels of the mini-tiller are not changed, the rotation directions of rotary blade shafts can be changed in the forward and reverse directions. Therefore the ditching function of the full-gear mini-tiller is achieved, the device is easy and convenient to operate, a protection cover doesnot need to be replaced during ditching, any other operation is not needed, and the ditching operation can be conducted only by stirring a shifting fork and arranging a cutter. Meanwhile, during machine movements such as mountain climbing, slope climbing and land parcel movements in the non-work period, the shifting fork only needs to be stirred, rotary blades cannot rotate, the walking wheels drive the device to walk, the safety is guaranteed, and the labor is saved.

Description

technical field [0001] The invention belongs to mechanical equipment for planting crops, and relates to a power transmission device for a tiller, more specifically, a full-gear transmission type power transmission device with a clutch, shifting and reversing device for a tiller. Background technique [0002] Tillers are commonly used operating equipment for agricultural farming machinery, especially widely used in small-scale cultivated land. Existing tillage machines are mainly divided into two classes, one is a two-drive tiller, and the other is a four-drive tiller. There are two main types of four-wheel drive tillers, one is the tiller with belt and chain transmission, and the other is the tiller with full gear transmission. Existing partial belt and chain-driven micro-tillers can realize the function of ditching, which is not available in current full-gear-driven micro-tillers. However, the micro tillage machine driven by belt and chain has the disadvantages of large s...
