the motor mounting bracket 70 is fixed on the upper surface of the frame 10;

the motor 80 is fixed on the motor mounting bracket 70, and the motor 80 is a servo motor;

the motor 80 is electrically connected with the PLC, the PLC controls the motor 80 to periodically rotate forwards and backwards, and the specific model of the PLC is S7-1200;

one end surface of the gear 90 is fixed with the free end of the rotating shaft of the motor 80, and the gear 90 is positioned between the two slide block rods 51;

the side surfaces of the two slide block rods 51 adjacent to each other are provided with a spur rack which is meshed with the gear 90;

the steps and the principle are as follows:

1) placing two wheels of the frame 10 on two sides of the ridge;

2) fixing a towing ring 11 of a frame 10 to a rear side of a tractor;

3) starting the PLC;

4) starting a tractor to run along the ridges;

when the channel assembly above the ridge advances, the carrot leaves firstly pass through the larger opening side of the outer plate connecting plate 43 and the inner plate connecting plate 44 and enter the channel formed by the outer plate 41 and the inner plate 42, when the carrot leaves reach the fixed blade 46, because the PLC control motor 80 periodically moves forwards and backwards, the slider rod 51 reciprocates along the guide rail 60, namely, the blade part 531 of the movable blade 53 is periodically jointed with the blade edge of the fixed blade 46, and when the blade part 531 of the movable blade 53 is jointed with the blade edge of the fixed blade 46, the carrot leaves between the blade part 531 of the movable blade 53 and the fixed blade 46 are cut off, so far, the mechanical cutting of the carrot leaves is completed instead of manual cutting.

Because the season that the carrot was reaped is generally winter, receives the difference of temperature and carrot variety, and the carrot cherry of some varieties can wilt on the ridge upper surface, and when the device was advanced along the ridge this moment, the device only can pass through from the carrot cherry upside, but the carrot cherry can not get into in the passageway that outer panel 41 and inner panel 42 formed.

Further, the air-conditioning system also comprises a fan 100,

the fan 100 is fixed on the upper surface of the rack 10, the wind direction of the fan 100 is from bottom to top, and the air duct of the fan 100 is communicated with the lower side of the rack 10;

step 5), starting the fan 100;

when the device advances along the ridge, the fan 100 sucks up the carrot leaves wilted on the ridge, and the standing carrot leaves enter the channel formed by the outer plate 41 and the inner plate 42 along with the advance of the device, and are cut off by the

cutting edge portions

531 and 46 of the movable blade 53.

Furthermore, the degree of the included angle between the inner side plate 42 and the bottom plate 45 is 90-60 degrees, and preferably, the degree of the included angle between the inner side plate 42 and the bottom plate 45 is 80-60 degrees;

when the included angle between the inner side plate 42 and the bottom plate 45 is 90 degrees, the carrot leaves wilted on the ridge are sucked up by the fan 100 and then enter the channel formed by the inner side plate 42 and the bottom plate 45, the carrot leaves are respectively and randomly fallen to the inner side plate 42 and the bottom plate 45, but when the carrot leaves falling to the side plate 42 are cut off by the movable blade 53 and the fixed blade 46, the top tips of the carrot leaves are respectively cut off and fall onto the upper surface of the ridge, and the recycling of the carrot leaves is not facilitated;

however, when the included angle between the inner side plate 42 and the bottom plate 45 is 80 to 60 degrees, the carrot tassel wilted on the ridge is sucked up by the fan 100 and then enters the channel formed by the inner side plate 42 and the bottom plate 45, and the carrot tassel is pressed to the inner side plate 42 by the inclined outer side plate 41 because the upper sides of the inner side plate 42 and the outer side plate 41 are inclined toward the bottom plate 45, so that the carrot tassel falls toward the bottom plate 45, and at this time, the integrity of the carrot tassel can be ensured when the carrot tassel is cut off by the movable blade 53 and the fixed blade 46.

During the operation of cutting carrot cherry, the carrot leaves wilted on the ridges are sucked up by the fan 100 and pressed against the inner side plate 42 through the inclined outer side plate 41, and when the field is windy, the carrot leaves fall to the bottom plate 45 randomly.

Further, the fan cover 110, the first pipe 120 and the air outlet head 130 are also included;

the fan cover 110 is fixedly arranged at an air outlet at the upper side of the fan 100;

one end of each of the two first pipes 120 is fixed on the fan cover 110, the first pipes 120 are communicated with the inside of the fan 100, and the free ends of the first pipes 120 are communicated with the air outlet head 130;

the upper side of the air outlet head 130 is provided with an air outlet 131, and the two air outlet heads 130 are respectively fixed on the two outer side plates 41.

When the carrot tassel wilted on the ridge is sucked up by the fan 100 and passes through the inclined outer plate 41 and presses the inner plate 42, the air outlet of the air outlet 131 blows the carrot tassel to the inner plate 42 even if wind exists in the field.

If the cut carrot tassel passes through the bottom plate 45 and falls to the upper surface of the ridge, the subsequent work of digging the carrot is not facilitated.

Further, a second tube 140, a channel 150,

one end of the channel 150 is fixed on one side of the inner side plate 42 far away from the traction ring 11, the channel 150 is communicated with a cavity formed by the two inner side plates 42, and the free end of the channel 150 points to a furrow between two adjacent ridges;

one end of the second pipe 140 passes through the fan cover 110 to communicate with the fan, the free end of the second pipe 140 passes through the frame 10 and extends to between the two inner side plates 42, and the second pipe 140 blows air to the channel 150.

The cut carrot tassel falls on the bottom plate 45 and is discharged through the air outlet end of the second pipe 140, and the carrot tassel falls in the furrow between two adjacent ridges through the channel 150.

The second tube 140 is made of a hard material.

The technical scheme in the embodiment of the application at least has the following technical effects or advantages:

because the carrot cherry passes through the great one side of outer panel connecting plate 43 and interior version connecting plate 44 opening earlier, gets into in the passageway that outer panel 41 and inner panel 42 formed, when the carrot tassel arrived fixed blade 46 department, because PLC control motor 80 periodic positive and negative motion, slider pole 51 is along guide rail 60 reciprocating motion, promptly the cutting edge portion 531 of movable blade 53 and the cutting edge of fixed blade 46 are periodic to be closed, when the cutting edge portion 531 of movable blade 53 and the cutting edge of fixed blade 46 were cut, just cut off the carrot tassel between them, accomplish the machinery and replace the manual work and cut off the carrot tassel so far.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
