[0003] However, the above-mentioned device still has obvious defects during use: although the above-mentioned device can adjust the distance between the blades, the position of its rotary tillage shaft is low and cannot be adjusted, so that the rotary tiller cannot be used in the field rotary tillage scenario of wheat-cotton intercropping. This is because the wheat-cotton intercropping method requires rotary tillage and sowing of cotton seeds in the reserved rows of the unharvested wheat field, and the rotary tillage shaft of the above-mentioned device will cause serious crushing of the unharvested wheat during the rotary tillage process, so the use scenarios of the above-mentioned device are limited.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6 , the utility model provides a technical solution:

[0023] Embodiment 1:

[0024] A rotary tiller with adjustable spacing for intercropping wheat and cotton, comprising a frame 1, the frame 1 being U-shaped, a main driving roller 2 being installed on one side of the U-shaped opening direction of the frame 1, a plurality of groups of rotary tilling units 3 being flip-mounted on the main driving roller 2, a limiting seat 4 being fixedly installed below the frame 1 and inside the U-shaped opening, the limiting seat 4 being used to limit the rotary tilling unit 3 in a horizontal or vertical direction, and the limiting seat 4 limiting the rotary tilling unit 3 thereby adjusting the working state of the corresponding rotary tilling unit 3, when the rotary tilling unit 3 is limited parallel to the frame 1, the rotary tilling unit 3 is in an idling mode, and when the rotary tilling unit 3 is limited perpendicular to the frame 1, the rotary tilling unit 3 is in a rotary tilling loosening mode;

[0025] The rotary tillage unit 3 includes a flip plate 5 arranged in parallel on the left and right sides, and the flip plates 5 on the left and right sides are installed on the main transmission roller 2 through a flip bearing 6. A rotary tillage shaft 7 is movably installed at one end of the flip plates 5 away from the main transmission roller 2, and a rotary tillage blade wheel 8 is installed on the rotary tillage shaft 7. The main transmission roller 2 and the rotary tillage shaft 7 are fixedly installed with corresponding sprocket wheels 9, and the corresponding sprocket wheels 9 are connected by chains 10. The main transmission roller 2 is connected to the power mechanism, and the rotation of the main transmission roller 2 drives the rotary tillage blade wheels 8 on each rotary tillage unit 3 to rotate.

[0026] In this embodiment, the frame 1 is used as a bearing device for various parts. Figure 4 The main body of the frame 1 is U-shaped, and a main transmission roller 2 is installed on one side of its opening. A transmission chain plate is installed on one side or both sides of the main transmission roller 2. The transmission chain plate is connected to the transmission sprocket on the diesel engine or the motor through a transmission chain, so that the power output by the diesel engine or the motor is transmitted to the main transmission roller 2. Since this structure is a common transmission mechanism in the prior art, it is not described in detail in this article. Several groups of rotary tillage units 3 are installed on the main transmission roller 2. The rotary tillage units 3 may adjust the working state by flipping. In order to ensure that they are in the corresponding working state, the rotary tillage units 3 are limited by setting a limit seat 4. Refer to the attached manual Figure 1-6 Since the original crops need to be protected during the intercropping process, the transmission shaft of the rotary tillage mechanism needs to be set at a higher position. Therefore, the main drive roller 2 of the present application is set on the frame 1, and the rotary tillage unit 3 is set perpendicular to the frame 1 in the rotary tillage loosening mode. This setting can ensure that the wheat crop can pass smoothly from the bottom of the frame 1 without causing any impact during the rotary tillage process. Similarly, in order not to damage the soil in the wheat row, the rotary tillage unit 3 adopts a flip setting. When there is a wheat crop in the travel range of the rotary tillage unit 3, the rotary tillage unit 3 is flipped upward to keep it parallel to the frame 1. At this time, the rotary tillage wheel 8 of the rotary tillage unit 3 is in an idling state. The working mode of the rotary tillage unit 3 is adaptively and freely adjusted according to the reserved row spacing, thereby realizing the technical solution of adjustable spacing. The rotational power of the rotary tillage wheel 8 comes from the main drive roller 2, which transmits power through a chain drive.

[0027] Embodiment 2:

[0028] A gripping wheel 11 is also installed at the rear end of the bottom of the frame 1 in the direction of travel of the vehicle body. The gripping wheel 11 is connected to the power output shaft of the diesel engine or the motor through a transmission mechanism to obtain the driving power.

[0029] A handrail 12 is also installed at one end of the frame 1 away from the rotary tillage unit 3 .

[0030] In this embodiment, the provision of the gripping wheels 11 can ensure the smooth advancement of the frame 1, and the provision of the handrails 12 can enable the operator to control the direction of travel.

[0031] Embodiment three:

[0032] The limit seat 4 for horizontally or vertically limiting the rotary tillage unit 3 includes a cross beam 13, which is fixedly connected to the frame 1. The cross beam 13 is equipped with limit latch seats 14 twice the number of the rotary tillage units 3. The limit latch seats 14 are translationally and slidably installed with limit latches 15. The flip plate 5 is correspondingly provided with latch holes 16 that cooperate with the limit latch 15. The limit latch seat 14 is also equipped with a limit spring 17 that pushes the limit latch 15 to cooperate with the latch hole 16 in the absence of external force. The limit latch 15 is manually turned to overcome the elastic force of the limit spring 17 to do work, thereby causing the limit latch 15 to disengage from the latch hole 16.

[0033] The structure of the limit seat 4 is further disclosed in this embodiment, which locks and limits the flip plate 5 through the cooperation of the limit pin 15 and the pin hole 16, thereby realizing the locking and limiting of the rotary tillage unit 3. When contact locking is required, it is only necessary to manually bend the limit pin 15 to disengage it from the pin hole 16.

[0034] Working principle: before rotary tillage, the rotary tillage unit 3 is turned over according to the row spacing of the reserved rows in the wheat-cotton intercropping field, so that the rotary tillage unit 3 in the direction of the empty row is in the rotary tillage loosening mode, and the rotary tillage unit 3 in the direction of the wheat growing row is in the idling mode. At this time, the machine is started to rotate the rotary tillage wheel 8, and the staff controls the direction of travel of the rotary tiller through the handrail 12. Through this setting, the soil in the empty row is rotary tilled and loosened, while the wheat planting row is not rotary tilled. Since the rotary tillage unit 3 has a longer flip plate 5, the wheat can pass through the bottom of the frame 1 smoothly during the rotary tillage process without alignment and causing damage.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
