Detailed ways

The present invention will be further described below in conjunction with Fig. 1 to Fig. 11 and embodiments.

As shown in Fig. 2 and Fig. 3, the stubble removal rotary tillage combined operation machine of the present invention comprises a rotary tiller body 1, and a gear box 11 is installed on the frame of the rotary tillage combined operation machine, and its two power output shafts are respectively driven The shaft connects the power input shaft of the stubble removal side gear box and the power input shaft (not shown) of the rotary tiller box; The power input shaft 221 and the power output shaft 222 are composed of the stubble removing side gear box 22 and the stubble removing cutter shaft 23, wherein the power input shaft 221 of the stubble removing side gear box 22 is connected with the power output shaft drive connection provided on the rotary tiller body (see Fig. 3); the upper ends of the stubble removal side gear box 22 and the stubble removal side arm 21 are respectively hinged on both sides of the rotary tiller body 1, one end of the stubble removal cutter shaft 23 is installed on the lower end of the stubble removal side arm, and the other end is installed on the power output of the stubble removal side gear box On the shaft 222, the stubble removal side arm and the stubble removal side gearbox are used as the support arms on both sides of the stubble removal cutter shaft; the stubble removal cutter is installed on the stubble removal cutter shaft; The output shaft 222 transmits power through the gear or chain in the stubble removal side gearbox; it also includes a lifting device 3 (as shown in Figure 4) for manipulating the stubble removal device to rise and fall, which is arranged between the rotary tiller body and the stubble removal device ( as shown in Figure 5).

The above-mentioned lifting device 3 can be various structures that can make the stubble removal device rise and fall, such as installing a hydraulic oil cylinder between the rotary cultivator body and the stubble removal device or through a four-bar linkage mechanism. organization as an example for further explanation.

As shown in Fig. 4 and Fig. 5, two supporting seats 31 are arranged oppositely on the body of the rotary tiller, and shaft holes are correspondingly arranged on the two supporting seats, and a lifting cross bar 32 is arranged in the shaft holes, so that The two ends of the above-mentioned landing bar 32 pass through the support seat 31, and the two ends are provided with two landing arms 33 of equal length; 21. The front ends of the stubble removal side gear box 22 are hinged; the lifting crossbar 32 is provided with an operating mechanism 5 that controls the rotation of the lifting crossbar to control the rise and fall of the stubble removal device.

Certainly, as above-mentioned improvement, also can also according to the situation of rotary cultivator body, can also be directly arranged on above-mentioned lifting bar 32 on rotary cultivator body 1 (referring to Fig. 7), helps to reduce product volume like this, reduces Cost, reduce the workload of installation and commissioning.

The above-mentioned operating mechanism can be in various forms, which will be further described below in conjunction with the accompanying drawings.

As shown in Figure 4, Figure 5, and Figure 6, the operating mechanism is: a ratchet plate 51 is provided on the support seat near the lifting crossbar (or on the body of the rotary tiller), and a ratchet plate 51 is installed at the corresponding position of the ratchet plate 51. A lever 52 perpendicular to the lifting and lowering lever is provided on the crossbar, and a ratchet 53 compatible with the ratchet plate is installed at the front of the lever 52, and a handle 54 is arranged at the rear of the lever. The handle link 55 controls the engagement and separation of the ratchet and the ratchet plate. As shown in Figure 6A, when the stubble removal device falls, the lever 52 is in a vertical state, and the ratchet 53 is engaged with the groove above the ratchet plate 51 to limit the rotation of the stubble removal device 2; when the stubble removal device 2 needs to be lifted, pull With the handle 54, the pawl is pulled out from the groove in the ratchet plate through the handle rod, so that the pawl 53 is separated from the ratchet plate 51, and then the handle is pressed down to lift the stubble removal device 2 hinged on the rotary tiller. When lifting to a suitable position, loosen the handle so that the ratchet 53 is inserted into the corresponding groove on the ratchet plate 51 (only two grooves are shown on the ratchet plate in the figure, and the number of the grooves can be set as required. Set), thereby the stubble removal device 2 is positioned, as shown in Figure 6B.

Fig. 7, Fig. 8, Fig. 9 show another kind of operating mechanism, and its structure is: a gear box 58 with worm gear 56 worm 57, wherein, worm gear 56 is arranged on the described lift cross bar 32, and worm gear 57 One end stretches out gear box 58 and is control end, and gear box casing is fixedly connected with rotary tiller body.
