The sixth sprocket 535 is connected to the sweeping shaft 221. When the fifth sprocket 534 rotates, the third chain 536 drives the sixth sprocket 535 to rotate, and further drives the cleaning shaft 221 to rotate, so that the fifth sprocket 534 and the sixth sprocket 535 can rotate by the third driving member 53, and the conveying shaft 1212 and the cleaning shaft 221 can rotate synchronously by the third driving member 53.

In other embodiments, a fourth driving member 54 is disposed between the sixth sprocket 535 and the sweeping shaft 221, the fourth driving member 54 includes a second gearbox 541, the second gearbox 541 can rotate when the sixth sprocket 535 rotates, so as to drive the sweeping shaft 221 to rotate, and the second gearbox 541 can control the rotation speed of the sweeping shaft 221.

It can be understood that, when the cleaning shaft 221 has a plurality of, the fourth driving part 54 has a plurality of, the cleaning shafts 221 and the fourth driving parts 54 correspond to each other one by one, a third transmission shaft 542 extending along the left-right direction is arranged between two adjacent fourth driving parts 54, and the third transmission shaft 542 can drive the fourth driving parts 54 to operate simultaneously, so as to drive the cleaning shafts 221 to rotate synchronously, and further drive the brush heads 222 to clean soil on the surface of the mulching film simultaneously.

Further, the fourth driving member 54 includes a fourth transmission shaft 543 and a coupling 544, the fourth transmission shaft 543 extends in the vertical direction, and the coupling 544 is provided between the fourth transmission shaft 543 and the cleaning shaft 221. When the sixth chain wheel 535 rotates, the fourth driving part 54 is driven to operate, so as to drive the fourth transmission shaft 543 to rotate, and further drive the cleaning shaft 221 to rotate by using the shaft coupling 544.

According to the potato seedling killing and mulching film recycling integrated machine 100, the first driving part 51, the second driving part 52, the third driving part 53, the fourth driving part 54 and the like are utilized to drive the seedling killing roller 1111, the conveying shaft 1212 and the cleaning shaft 221 to synchronously rotate, the seedling killing operation, the cleaning operation and the film collecting operation are completed simultaneously, and the working efficiency is high.

Specifically, the seedling killing knives 112 rotate at a high speed to kill seedlings by connecting the tractor with the first driving part 51 of the potato seedling killing and mulching film recycling integrated machine 100, the seedlings are smashed by the seedling killing knives 112 and fall into the hopper 122 to be discharged in time through the transmission of the second driving part 52, and after the speed is reduced by the third driving part 53 and the fourth driving part 54, the power is transmitted to the cleaning assembly 22.

For example, the output rotation speed of the traction driver is 540r/min, when the rotation speed is transmitted to the seedling killing roller 1111 after the speed change of the first gearbox 511 and the gearbox 513, the rotation speed of the seedling killing roller 1111 reaches 1440r/min, the power is transmitted to the transmission shaft 1212 through the transmission of the second driving part 52, the transmission ratio is 1:6, the transmission shaft 1212 discharges seedlings in time at the rotation speed of 240r/min, the rotation speed is reduced again 541 after the transmission of the third driving part 53 and the fourth driving part 54, the output rotation speed of the second gearbox is 60r/min, namely the rotation speed of the brush head 222 is 60 r/min.

In the process of carrying out film collecting operation on the potato seedling-killing and mulching film recycling integrated machine 100, in order to collect mulching films, the linear speed of the film rolling roller is consistent with that of the potato seedling-killing and mulching film recycling integrated machine 100, in other words, the speed of the potato seedling-killing and mulching film recycling integrated machine 100 is high, and the linear speed of the film rolling roller is increased; the speed of the potato seedling killing and mulching film recycling integrated machine 100 is low, and the linear speed of the film rolling roller is reduced accordingly.

In some embodiments, the integrated potato seedling killing and mulching film recycling machine 100 further comprises a second driving assembly 6, and the second driving assembly 6 is respectively connected with the soil crushing assembly 21 and the film rolling assembly 32 so as to drive the film rolling roller and the soil crushing roller 211 to rotate.

The soil crushing roller 211 rotates by means of friction force between the soil crushing roller 211 and the surface of the ridge body, namely the linear speed of the soil crushing roller 211 is the same as that of the potato seedling killing and mulching film recycling all-in-one machine 100. According to the integrated machine 100 for seedling killing and mulching film recycling of potatoes, disclosed by the embodiment of the invention, when the soil crushing roller 211 rotates, the second driving assembly 6 drives the film rolling roller to rotate, so that the linear speeds of the film rolling roller and the soil crushing roller 211 are kept consistent, and further, the film rolling speed of the film rolling roller is kept consistent with the advancing speed of the integrated machine 100 for seedling killing and mulching film recycling of potatoes.

It should be noted that, because the mulching film is wrapped in the soil on the surface of the ridge body, the mulching film is necessarily pulled by the film rolling roller at an excessively high speed, and the mulching film is torn seriously, so the normal running speed of the integrated machine 100 for killing the seedlings of the potatoes and recycling the mulching film cannot be greater than 1m/s, when the integrated machine 100 for killing the seedlings of the potatoes and recycling the mulching film advances at a low speed, enough time just can be provided for the cleaning unit 2 to perform the cleaning work of the soil on the film surface, that is, the film rolling roller and the soil crushing roller 211 rotate at a constant speed, and when the integrated machine 100 for killing the seedlings of the potatoes and recycling the mulching film runs at a speed of 1m/s, the rotating speed of the film rolling roller is 48 r/min.

In an embodiment of the present invention, the second drive component 52, the third drive component 53 and the second drive assembly 6 are chain drives in order to accommodate the harsh environment of the field. It will be appreciated that in other embodiments, the second drive member 52, the third drive member 53 and the second drive assembly 6 may also be belt driven mechanisms, or the second drive member 52, the third drive member 53 and the second drive assembly 6 may be driven by motors, respectively.
