[0041] The ditching mechanism of this tractor has two working modes:

[0042] Mode 1: When the ditching mechanism is used for ridge cultivation, since crops are planted on ridges, the soil on the ridges needs to be kept loose. Figure 1 , the guide assembly 6 is separated from the ridging shaft 7, and the ridging shaft 7 is used to trim the soil pile to form soil ridges on both sides of the ditch. The following working steps of the ditching mechanism are included:

[0043] The bottom of the furrow opener 3 is kept slightly higher than the bottom of the rotary tillage tool 2. After the rotary tillage tool 2 tills the ground 10, the furrow opener 3 follows the tractor to dig furrows on the ground 10 after the rotary tillage tool 2 has tilled the ground. The ridging wheel 4 trims the soil pile behind the furrowing plate 32 behind the furrow opener 3 to form a soil ridge.

[0044] Mode 2: When the ditching mechanism is used for ditching, since crops are planted in the ditch, the soil in the ditch needs to be kept loose, and the ridge is used to keep the moisture in the ditch. The soil of the ridge needs to be compacted to guide the water down into the ditch. Therefore, in this mode, refer to Figure 2 The guide assembly 6 is combined with the ridging shaft 7. The ridging shaft 7 is used to trim and compact the soil to form a soil ridge. The guide assembly 6 is used to retain some loose soil on the soil ridge for soil cultivation during planting in the ditch. The furrowing mechanism in mode 2 includes the following working steps:

[0045] refer to Figure 2 and Figure 3 The plate adjustment assembly 5 adjusts the position of the guide assembly 6 so that the limiting sleeve 64 is placed on the ridging shaft 7, the front end of the guide plate 61 extends to the front of the ridging shaft 7, and the rear end of the guide plate 61 extends to the rear of the ridging shaft 7, and then the inclination angle of the guide plate 61 is adjusted to facilitate the soil to enter the guide plate 61.

[0046] refer to Fig. 9 After the rotary tillage tool 2 tills the ground 10, the furrow opener 3 follows the tractor to dig furrows on the ground 10 after the rotary tillage tool 2 has tilled the ground. The bottom of the furrow opener 3 is higher than the bottom of the rotary tillage tool 2 by an appropriate height, so that the bottom of the furrow opener 3 retains the soil after rotary tillage to form furrow planting soil 11; the ridging wheel 4 trims the soil pile behind the furrowing plate 32 behind the furrow opener 3 to form a soil ridge. Before the ridging shaft 7 trims the soil pile, the guide plate 61 guides some of the soil blocks in front of the ridging shaft 7 to the rear of the ridging shaft 7, and a fluffy layer 8 is formed on the upper part of the compacted compact layer 12 behind the ridging shaft 7, which is used for soil cultivation during planting in the furrow. The ridging shaft 7 trims and compacts the soil in front of it that has not been diverted to form a compact layer 12 for rainwater diversion and rainwater collection in the furrow.

[0047] Example 2

[0048] The difference between this embodiment and embodiment 1 is that Fig.10 In this embodiment, a paddle 9 is arranged above the guide plate 61, and the paddle 9 is used to paddle the soil blocks on the guide plate 61 from the front to the outside and back to assist the soil blocks on the guide plate 61 to enter the rear of the ridging shaft 7 from the front of the ridging shaft 7.

[0049] refer to Fig.10A connecting base 91 is fixedly arranged below the plate adjustment assembly 5, and a walking channel 93 and a walking rod 92 that walks along the walking channel 93 are arranged on the connecting base 91.

Rotating connecting blocks 97 that are rotatably connected to the walking rod 92 are arranged at both ends of the walking rod 92, and the rotating connecting blocks 97 are connected to the paddle 9 through the second connecting rod 98, and the paddle 9 can follow the walking rod 92 to walk along the walking channel 93. Among them, the path of the toggle channel corresponds to the extension route of the guide plate 61. When the walking rod 92 passes through the toggle channel, the paddle 9 is used to toggle the soil blocks on the guide plate 61, and the auxiliary soil blocks enter the rear of the ridging shaft 7 from the front of the ridging shaft 7. The walking rod 92 moves in the return channel, and the bottom of the paddle 9 does not contact the soil blocks on the guide plate 61. The walking rod 92 returns from the tail end of the toggle channel to the head end of the toggle channel. The walking rod 92 cyclically moves in the shifting channel and the return channel, so that the shifting piece 9 can continuously and unidirectionally shift the soil blocks on the guide plate 61 .

[0050] refer to Fig.10 and Fig.11 , a walking block 94 is provided on the connecting base 91, a first driving cylinder 95 is provided on the walking block 94, a working end of the first driving cylinder 95 is fixedly connected to a rotating connecting block 97, and the walking block 94 is connected to the connecting base 91 through a second driving cylinder 96, and the second driving cylinder 96 is arranged perpendicular to the axis of the first driving cylinder 95. The second driving cylinder 96 is used to push the walking block 94 to move in the horizontal direction, and the first driving cylinder 95 is used to push the rotating connecting block 97 to move in the vertical direction. The second driving cylinder 96 cooperates with the first driving cylinder 95 to realize the movement of the paddle 9 along the walking channel 93, so as to realize the continuous unidirectional movement of the paddle 9 to the soil blocks on the guide plate 61.

[0051] When the guide assembly 6 is separated from the ridging shaft 7, the limiting sleeve 64 leaves the ridging shaft 7. At this time, the walking rod 92 is located in the return channel of the walking channel 93, and the paddle 9 is away from the guide plate 61, giving the guide plate 61 and the limiting sleeve 64 space to move upward.
