[0002] As one of the most critical steps in agricultural planting, sowing plays a decisive and key role in agricultural output. At present, the agricultural land in the northwest region is vast, especially in Xinjiang, where the land transfer area is vast, which is suitable for large-scale agricultural machinery operations. However, the temperature difference between day and night in Xinjiang is large, with long winter and summer seasons and short spring and autumn seasons. During sowing, large-scale mechanical sowing and film laying are used to achieve the effect of increasing temperature, moisture retention and increasing yield.

[0003] However, when the seeder is performing film laying operations, the thickness and toughness of the mulch film are gradually increasing due to the increasing national requirements for the recycling of residual mulch film. This makes the mechanical sawtooth film cutter of the original mulch laying seeder incomplete in cutting the film, and the mulch film with increased thickness and toughness cannot be completely torn, which requires manual film cutting. This leads to waste of mulch film and human resources, affecting the development of intelligent agriculture. Utility Model Content

[0026] [Example 1]

[0027] See also Figure 1-5The utility model provides a technical solution: a new electric film cutting device for a film laying seeding machine. The housing of the new electric film cutting device consists of a left housing 1 of the device and a right housing 5 of the film cutting device. A knife rod through hole 7 is provided on both sides. The gap of the entire device housing is controlled by a fixing screw 3.

[0028] Specifically, the knife bar through hole 7 can pass through the knife bar of the film-laying seeding machine. During installation, turn the fixing screw 3 until the left shell 1 of the device is separated from the right shell 5 of the device, set the length of the film-breaking knife, first pass the knife bar through hole 7 of the left shell 1 of the device through the knife bar, so that the left drive wheel 17 is tangent to the left side of the knife bar, and then pass the knife bar through hole 7 of the right shell 5 of the device through the knife bar, so that the right drive wheel 8 is tangent to the right side of the knife bar, align the two side shells in parallel, and slightly adjust so that the auxiliary fixing wheel 4 is tangent to the upper surface of the knife bar. At this time, tighten the fixing screw 3 to fix the device on the knife bar of the film-laying seeding machine. After the device is installed firmly, insert the lithium battery 12.

[0029] The auxiliary fixed wheel 4 is fixed by a fixed wheel rotating shaft 20 passing through the fixed wheel rotating shaft through hole 19. The two ends of the fixed wheel rotating shaft 20 are respectively inserted into the through holes in the fixed columns 6 of the outer shell on both sides of the device. When the device is in motion, the auxiliary fixed wheel 4 can move with the device on the upper side of the knife rod.

[0030] The fixing column 6 is composed of two parts, namely, the left housing 1 and the right housing 5. A fixing wheel shaft through hole 19 is provided to insert the fixing wheel shaft 20.

[0031] In the present embodiment, the right housing 5 of the device is further provided with a film cutting knife groove 11. Symmetrical semicircular columnar protrusions are provided on both sides of the knife groove 11, and the semicircular columnar protrusions on both sides can clamp the film cutting knife position fixing point 23, which is used to control the direction and length of the film cutting knife 22. The film cutting knife 22 is composed of a blade fixing end 25, a blade 10, a blade position control button 15, and a blade defect infrared detection device 24. When the length of the film cutting knife 22 is set, the blade position control button 15 is pressed to lift the film cutting knife position fixing point 23. When the film cutting end of the control blade 10 just passes through the ground film, the blade position control button 15 is released, the film cutting knife position fixing point 23 falls, and the symmetrical semicircular columnar protrusions at both ends of the knife groove 11 clamp the film cutting knife position fixing point 23 to fix the length of the film cutting knife 22.

[0032] The blade defect infrared detection device 24 is connected to the controller 21. When the blade 10 falls off due to mechanical wear or the blade fixing end 25 is damaged, the blade defect infrared detection device 24 detects that the blade 10 is abnormal and transmits an abnormal signal to the controller 21. The controller 21 uploads the abnormal information to the cab to remind the operator to stop the car for inspection and replace and repair the film cutting blade 10, thereby realizing intelligent fault monitoring of the film cutting blade.

[0033] In this embodiment, an antenna 2 is further provided outside the left housing 1 of the device. The antenna 2 is connected to the controller 21 and is used to receive the film cutting instruction from the cab. When the film cutting instruction is received, the controller 21 controls the driving mechanism to act.

[0034] The drive mechanism is symmetrically arranged on both sides and is respectively located in the housings on both sides of the device. The left drive mechanism is composed of a left DC motor 16, a rotating shaft 26, a left driving wheel 17 and a left gear 18; the right drive mechanism is composed of a right DC motor 14, a rotating shaft 9, a right driving wheel 8 and a right gear 13. The left DC single-machine rotating shaft 26 of the left DC motor 16 is connected to the left driving wheel 17 through the left gear 18; the right DC motor rotating shaft 9 of the right DC motor 14 is connected to the right driving wheel 8 through the right gear 13. The left and right motors are both connected to the controller 21, and the controller 21 controls the corresponding speed and direction of the DC motor. When in action, the left DC motor 16 and the right DC motor 14 rotate in opposite directions and at the same speed. The device moves from the starting point of one end of the knife rod to the end point of the other end of the knife rod along with the drive mechanism. The film cutting knife 22 is set with a suitable length, and as the device moves, the ground film is completely cut from one end to the other end. When the device reaches the end point, the controller 21 controls the left DC motor 16 and the right DC motor 14 to rotate in the opposite direction at a faster speed, so that the device as a whole returns to the starting point along the knife rod, completing a film cutting operation and waiting for the antenna 2 to receive the next film cutting operation instruction.

[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.
