Abstract
The invention relates to a colter speed change gear box matched with a walking tractor. The colter speed change gear box comprises a box body, an input gear, an input shaft, an intermediate gear, an intermediate shaft, a colter transmission gear, a colter transmission shaft, an engagement sleeve and an operation rod. During work, the input gear is engaged with a walking tractor chassis speed change box gear to obtain power, and power is transmitted to the intermediate gear and then transmitted to the colter transmission gear. When the operation rod is shifted to enable the engagement sleeve to be engaged with the colter transmission gear, the colter transmission gear drives the colter transmission shaft to rotate through the engagement sleeve and output power. When the operation rod is shifted to enable the engagement sleeve to be separated from the colter transmission gear, the colter transmission gear idles, and the colter transmission shaft does not output power. The colter speed change gear box integrates functions of an intermediate transmission box and a colter speed change gear box, the structure is compact, gears, shafts and other components in the box body are firm and durable, and the adverse influences in the aspects such as operation due to increasing of the diameter of a paddy wheel are greatly relieved.

Detailed description of the invention
By describing the technology contents of the present invention in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate attached
Figure is explained.
The design of most critical of the present invention is: middle driving box and colter change gear box are united two into one.
Refer to shown in Fig. 1 to Fig. 5, the colter change gear box of the walking tractor matching of the present invention, including casing 1,
Input gear 2, power shaft 3, idler gear 4, jackshaft 5, colter travelling gear 10, colter power transmission shaft 7, engaging sleeve 8 and manipulation
Bar 9；The connector for being arranged in the frame of agricultural machinery and implement by casing 1, described input gear 2, power shaft it is provided with on casing 1
3, idler gear 4, jackshaft 5, colter travelling gear 10, colter power transmission shaft 7 and engaging sleeve 8 are arranged in casing 1, described input
Gear 2 is arranged on power shaft 3, and described idler gear 4 is arranged on jackshaft 5, described colter travelling gear 10 and engaging sleeve 8
It is arranged on colter power transmission shaft 7；Described input gear 2 is meshed with idler gear 4, described idler gear 4 and colter driving cog
Wheel 10 is meshed, and described stick 9 is arranged on casing 1, and the engaging sleeve 8 in casing 1 is inserted to control in the struck side of stick 9
Engaging sleeve 8 and colter travelling gear 10 engage or separate, thus carry out the powerdriven clutch for clutch control of colter power transmission shaft 7.
In the above-described embodiments, as it is shown in figure 1, the part flank of tooth of input gear 2 stretches out outside casing 1 so that can during work
It is engaged obtaining power with the gearbox gear by input gear 2 with walking tractor chassis.
In the above-described embodiments, power shaft 3, jackshaft 5 and colter power transmission shaft 7 are rotatably arranged in casing 1, rotate
The mode connected can be to be respectively mounted bearing at the two ends of power shaft 3, jackshaft 5 and colter power transmission shaft 7, is fixed by bearing
In casing 1, as shown in Fig. 2, Fig. 4 and Fig. 5.Certainly, the invention is not limited in the above-mentioned mode being rotationally connected, any existing

Power transmission shaft 7 rotates, and when engaging sleeve 8 separates with colter travelling gear 10, colter power transmission shaft 7 does not rotate and do not exports power, thus
Realize output or the closedown of power.
The operation principle of the present invention is as follows:
During work, engage acquisition power by input gear 2 with walking tractor chassis gearbox gear and be delivered to centre
Gear, is delivered to colter travelling gear 10 the most again；Stirring stick 9 makes engaging sleeve 8 engage (dental inlay with colter travelling gear 10
Engagement) time, colter travelling gear 10 drives colter power transmission shaft 7 to rotate output power by engaging sleeve 8；Stir stick 9 to make to nibble
When trap 8 separates with colter travelling gear 10, colter travelling gear 10 dallies, and colter power transmission shaft 7 does not rotate and do not exports power.
Knowable to foregoing description, the beneficial effects of the present invention is: use the colter change gear box of said structure, have concurrently
Middle driving box and the function of colter change gear box, without additionally installing middle driving box additional during use, thus reach to simplify knot
Structure, save installing space, alleviate due to diameter of paddy wheel strengthen the tractor agricultural machinery and implement unit center of gravity brought improve and rear move to
The purpose of adverse effect that operation brings, and saved installing space may be used for strengthening power shaft, input gear, in
Countershaft and the diameter of idler gear, thus it is greatly improved their structural strength, make the parts such as casing internal gear and axle firm resistance to
With, it is hardly damaged, improves service life.
Further, described connector includes left connecting tube 6 and right connecting tube 11, described left connecting tube 6 and right connecting tube
11 are connected in the left and right both ends of the surface of casing 1.
Knowable to foregoing description, the beneficial effects of the present invention is: casing is fixed by left connecting tube and right connecting tube
Being connected in the frame of agricultural machinery and implement, simple in construction, easy for installation, stable connection is reliable.
Further, described input gear 2, idler gear 4 and colter travelling gear 10 distribution triangular in shape.Such as Fig. 1 institute
Showing, jackshaft is arranged at the upper right side of power shaft, and colter power transmission shaft is arranged at the lower right of power shaft.
Knowable to foregoing description, the beneficial effects of the present invention is: use above-mentioned design, whole body structure can be made tight
Gather, under conditions of meeting diameter of paddy wheel, reduce and on agricultural machinery and implement, move size and rear shifting size, significantly alleviate owing to paddy field wheel is straight
The adverse effect that center of gravity improves and rear shifting brings making tractor agricultural machinery and implement unit is strengthened in footpath to aspects such as operations.
In the above-described embodiments, described idler gear 4 can be individual gears, as shown in Figure 2；Or be duplicate gear, such as Fig. 4
Shown in, when using duplicate gear, two numbers of teeth can be made to take different value, thus change the rotating speed of colter power transmission shaft 7；Or be 2 with
The individual gears that axle is arranged, during as it is shown in figure 5, use 2 individual gears, the number of teeth of 2 individual gears can take different value, thus change
The rotating speed of colter power transmission shaft 7.
In sum, the colter change gear box of the walking tractor matching that the present invention provides, compact conformation, casing internal tooth
