[0040] Example

[0041] like Figure 1-7 As shown, the utility model discloses a ground film sorting machine, which comprises an angle iron bracket 1, a ground film conveying assembly fixed above the angle iron bracket 1, an impurity conveying assembly fixed below the ground film conveying assembly, and a power transmission assembly.

[0042] The mulch conveying assembly includes a mulch conveying roller shell 2, a mulch conveying roller 3 and a filter screen 4 arranged in the mulch conveying roller shell 2; the mulch conveying roller shell 2 is provided with a material inlet 7 and a mulch outlet 8 at both ends, and the mulch conveying roller shell 2 is provided with a support flange 5 at one end thereof, and one end of the mulch conveying roller shell 2 provided with the mulch outlet 8 is bolted to the support flange 5, and one end of the mulch conveying roller 3 passes through the support flange 5 and matches with the bearing seat 6, and there is a support platform on the support flange 5, and a platform opening is provided on the support platform and fixed with the bearing seat 6 by bolts. The other end of the mulch conveying roller 3 is also matched with the bearing seat 6, and there is a set screw in the bearing seat 6, which can limit the mulch conveying roller 3 axially.

[0043] Two groups of filter screens 4 are provided, and both ends of the two groups of filter screens 4 are connected to the outer shell 2 of the mulch conveyor roller by hinges 11. One side of the hinge 11 is welded to the outer shell 2 of the mulch conveyor roller, and the other side is welded to the filter screen 4. The filter screen 4 is fixed to the lower opening of the outer shell 2 of the mulch conveyor roller, and the mulch conveyor roller 3 is contained therein. The other side of the filter screen 4 is provided with a lock, which cooperates with the hinge 11 welded on the outer shell 2 of the mulch conveyor roller on this side to complete the opening and closing of the filter screen 4.

[0044] Spiral teeth 9 are evenly distributed on the mulch conveying roller 3, and a discharge blade 10 is provided at one end of the mulch conveying roller 3 near the mulch outlet 8. After the mulch mixture enters from the material inlet 7, it moves forward along the spiral teeth 9 on the roller under the high-speed rotation of the mulch conveying roller 3. When the mixture moves to the filter screen 4, the heavier impurities pass through the filter screen 4 under the action of centrifugal force and gravity, and the lighter mulch part is still pushed forward along the spiral teeth 9 on the mulch conveying roller 3 until the discharge blade 10. Under the push of the discharge blade 10, the mulch is discharged along the mulch outlet 8.

[0045] The impurity conveying assembly includes an auger shell 14 and an auger 15 arranged in the auger shell 14. Four groups of shell brackets 12 are welded on the outer wall of the ground film conveying roller shell 2. Both sides of the four groups of shell brackets 12 are provided with lug connection protective covers 13. A hinge 11 is welded to the lower end of the protective cover 13. The other end of the hinge 11 is welded to the auger shell 14. An impurity outlet 16 is arranged below one end of the auger shell 14. One end of the auger 15 cooperates with the bearing seat 6. A locking screw is arranged in the bearing seat 6 to limit the auger 15 axially. The other end cooperates with the large pulley 20 in the power transmission assembly.

[0046] A motor placement platform 17 is provided above one end of the auger housing 14 near the large pulley 20. The power transmission assembly includes a power motor 18, which is placed on the motor placement platform 17. A small pulley 19 is provided on the power motor 18. The small pulley 19 on the motor is responsible for transmitting torque and driving the large pulley 20 to rotate. Key slots are provided in both the large and small pulleys 19 to transmit torque. The heavier impurities in the ground film will eventually fall into the auger housing 14 through the filter 4. The auger 15 rotates at high speed under the torque provided by the power motor 18, pushing the impurities in the ground film to the impurity outlet 16, thereby discharging the impurities.

[0047] Working principle: After the device is powered on, the auger 15 and the ground film conveying roller 3 start to rotate at high speed under the action of the motor. When the motor reaches the rated speed, the ground film impurity mixture enters the channel formed by the ground film conveying roller shell 2 and the ground film conveying roller 3 through the material inlet 7. Due to the different masses of ground film and other impurities (straw, sand, drip irrigation belt, etc.). At the beginning, under the joint action of the high-speed rotation of the ground film conveying roller 3 and the spiral teeth 9, the ground film and impurities move forward along the channel formed by the ground film conveying roller shell 2 and the ground film conveying roller 3. When it moves to the position of the filter screen 4, impurities with larger mass except the ground film will pass through the filter screen 4 under the action of centrifugal force and gravity, and fall into the impurity conveying channel under the constraint of the protective cover 13. The impurities move forward along the channel formed by the auger shell 14 under the action of the auger 15, and are finally discharged through the impurity outlet 16; the ground film with lighter mass continues to move forward along the channel of the ground film conveying part, and is finally discharged through the ground film outlet 8, and the separation of ground film and impurities is completed.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
