[0001] The utility model belongs to the field of agricultural machinery, and particularly relates to a residual film picking-up device and a residual film recycling machine composed thereof. Background Art

[0002] After the plastic film is used, mechanical equipment is needed to recycle the residual film in the field. Chinese patents CN213819136, CN215648104, CN217656950, and CN217608233 all disclose residual film picking-up mechanisms. Although the residual film operation can be achieved, there are mainly problems such as a relatively high failure rate and poor film stripping effect of the picked-up residual film. How to reduce the failure rate or improve the film stripping effect can not only optimize the use of this model but also reduce the planting cost of farmers.

[0003] Therefore, a residual film picking-up device with a low failure rate, low use cost, simple structure, and convenient film withdrawal, and a residual film recycling machine composed thereof are proposed. Summary of the Invention

[0012] As a further improvement, the waste removing auger 1, the cleaning brush roller A13, the cleaning brush roller B14, the cleaning brush roller C15, and the cleaning brush roller D17 are arranged outside the area stretched by the film lifting roller A2, the film lifting roller B5 and the film lifting roller C8.

[0013] The utility model discloses another residual film picking-up device, which includes a frame 3. A picking-up mechanism is provided on the frame 3. The picking-up mechanism includes a film lifting belt 7, hook teeth 6, a film lifting roller A2, a film lifting roller B5, and a film lifting roller C8. It is characterized in that: a film stripping roller B26 is provided on the film lifting roller B5, the diameter of the film stripping roller B26 is larger than that of the film lifting roller B5, a film stripping roller A9 is provided on the film lifting roller C8, the diameter of the film stripping roller A9 is larger than that of the film lifting roller C8, a gap is left between the film stripping roller A9 and the film stripping roller B26, the film lifting roller A2, the film lifting roller B5, and the film lifting roller C8 form a fixed triangle, the film lifting belt 7 is wound around the film lifting roller A2, the film lifting roller B5, and the film lifting roller C8, and can bypass through the gap between the film stripping roller A9 and the film stripping roller B26.

The film lifting roller B5 is arranged in front of or directly above the film lifting roller A2. The hook teeth 6 are fixed on the film lifting belt 7 for lifting the plastic film.

[0014] In actual use: The film-lifting belt 7 is wound around three film-lifting rollers. The rotation of the film-lifting rollers drives the rotation of the film-lifting belt 7. The hook teeth 6 pick up the plastic film from the ground and move upward along the front part of the triangle formed by the three film-lifting rollers. When it moves to the film-lifting roller B5, under the action of the film-removing roller B26, the plastic film can be lifted from the root to the tip of the hook teeth. At this time, part of the impurities on the plastic film can be removed. When the plastic film runs to the film-lifting roller C8, under the action of the film-removing roller A9, the plastic film is peeled off from the hook teeth. That is, the plastic film is lifted from the root to the tip of the hook teeth at the film-lifting roller B5. When the plastic film runs to the film-lifting roller C8, the separation of the residual film and the hook teeth is completed. By using two film-removing rollers, impurities can be removed and the film and teeth can be separated more efficiently.

[0016] By setting the film-lifting roller B5 as the driving wheel and the film-lifting roller C8 as the driven wheel, during actual operation, the film-lifting belt on the picking-up side is stressed. When the film-lifting belt moves from the film-lifting roller B5 to the film-lifting roller C8, the film-lifting belt is in a non-stressed state and can move in cooperation with the film-lifting roller C8, which can reduce the failure rate and avoid belt damage.

[0017] As an improvement, the film-lifting roller C8 is a tensioning wheel, and the film-lifting roller C8 can reciprocate relative to the frame. By moving the film-lifting roller C8, the shape of the fixed triangle formed by the film-lifting roller A2, the film-lifting roller B5, and the film-lifting roller C8 can be changed.

[0018] Since the film-lifting belt is made of rubber material, there may be a risk of breaking the film-lifting belt when encountering a large load during operation. Therefore, setting the film-lifting roller C as a profiling wheel can increase the service time of the working machine and reduce the failure rate.

Compared with Example 1, the difference of this embodiment is that the outer surface of the film stripping roller A9 and / or the film stripping roller B26 is provided with a soil discharge wheel groove 9-1, and the soil discharge wheel groove 9-1 is arranged in a ring shape.

[0066] The discharge wheel groove 9-1 is an annular groove on the circumferential surface of the film stripping roller 9. When the residual film is stained with oil and fine soil particles, the fine soil particles can be discharged from the discharge wheel groove 9-1 when the residual film and the film stripping roller contact.

[0067] The outer surface of the film stripping roller refers to the contact surface with the residual film, which is the cylindrical surface of a columnar body.

[0068] Example 7: Reference Figure 8 or Figure 9 , is a structural schematic diagram of Example 7 of the utility model. Compared with Example 1, the difference of this embodiment is that: a profiling mechanism is provided, and the structure of the profiling mechanism is: it includes a profiling track 10, and a slide groove is provided on the profiling track 10. The rotating shaft of the film-lifting roller C8 is arranged in the slide groove, and the rotating shaft of the film-lifting roller C8 is provided with a buffer spring 21, so that the film-lifting roller C8 can move left and right in the slide groove of the profiling track 10; or, the structure of the profiling mechanism is: it includes a fixed arm 19 and a tension spring 20, one end of the fixed arm 19 is hinged on the frame 3, and the film-lifting roller C8 is arranged at the other end of the fixed arm 19, and the tension spring 20 is arranged between the fixed arm 19 and the frame 3, and the tension spring 20 pulls the film-lifting roller C8 in the direction of stretching the film-lifting belt 7.

[0069] The film-lifting roller C is profiled by a profiling mechanism, which includes a profiling track 10, on which a slide groove is provided, in which the rotating shaft of the film-lifting roller C8 is arranged, and the rotating shaft of the film-lifting roller C8 is provided with a buffer spring 21, so that the film-lifting roller C8 can move left and right in the slide groove of the profiling track 10; or: the profiling mechanism includes a fixed arm 19 and a tension spring 20, one end of the fixed arm 19 is hinged on the frame 3, and the film-lifting roller C8 is arranged at the other end of the fixed arm 19, and the tension spring 20 is arranged between the fixed arm 19 and the frame 3, and the tension spring 20 pulls the film-lifting roller C8 in the direction of stretching the film-lifting belt 7.

The transmission mechanism 23 includes: a power input shaft 28, a universal joint A29, a telescopic shaft sleeve A30, a transmission shaft 31, a telescopic shaft sleeve B32, a universal joint B33, and a gearbox 34. The universal joint A29 is arranged between the telescopic shaft sleeve A30 and the power input shaft 28. The universal joint B33 is arranged between the telescopic shaft sleeve B32 and the gearbox 34. The telescopic shaft sleeve A30 and the telescopic shaft sleeve B32 are sleeved on the transmission shaft 31. When the distance between the universal joint A29 and the universal joint B33 increases or decreases, the telescopic shaft sleeve A30 and the telescopic shaft sleeve B32 can slide on the transmission shaft 31, and any end of the transmission shaft 31 will not slip out of the sleeved telescopic shaft sleeve.

[0079] During actual use: The traction frame 27 is connected to the tractor. When turning is required at the end of the field during operation, a telescopic shaft sleeve is sleeved on the transmission shaft 31, and the distance between the universal joint A29 and the universal joint B33 is adjusted through the telescopic shaft sleeve sleeved on the transmission shaft, which is convenient for operation and improves work efficiency.
