Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a residual film recovery device, a residual film recovery machine and a working method. Background Art

[0002] The application and promotion of mulching technology has brought huge economic benefits to agricultural production. At the same time, the residual mulch has caused great pollution to the soil environment. As a currently economical and practical machine, the spring-tooth chain rake residual film recycling machine has begun to be widely used. After the spring teeth collect the residual film from the soil layer, whether the residual film can be removed to the film collection box in a timely and effective manner directly affects the operation effect of the whole machine. Therefore, the film removal device is a key component of the residual film recycling machine.

[0003] Patent CN201520691841.1, invented a film stripping device for a rake tooth residual film recovery machine, the rake tooth frame of the device has fixed and spaced rake teeth, and the two sides of the rake tooth frame are respectively equipped with a scraper film stripping mechanism driven by a driving device, and the scraper film stripping mechanism removes the accumulated residual film debris. Patent CN201420658125.9, a film stripping device for a residual film recovery machine, invented a film stripping plate installed on a roller, the free end of the film stripping plate is a nail tooth or a brush, and the residual film on the spring teeth is scraped off by rotating contact. Patent CN 201620546705.8, a film stripping machine with spring teeth self-unloading, invented a scraper-type film stripping device driven by a hydraulic motor, and the residual film on the spring teeth is scraped off by the rotating contact of the film stripping plate. The inventor found that the structures used for film stripping of spring teeth in the above patents all scrape off the residual film on the spring teeth through a rotating film stripping plate or a brush, and have a certain film stripping effect. However, the residual film is flexible and easily entangled. At the same time, since the spring teeth need to be inserted into the soil during operation, the residual film on the field surface is easily entangled in the middle and upper parts of the spring teeth. Under the influence of external factors such as soil agitation and vibration, it is very easy to get tightly entangled or dead knots. It is difficult to clean the residual film on the spring teeth at one time by simply relying on vibration or rotation of the scraper. The residual film is very likely to affect the operation of other parts of the residual film recycling machine, and in severe cases it will cause shutdown, seriously affecting the stability of the residual film recycling machine.

The two chain transmission mechanisms each include a driving sprocket, a driven sprocket and a transmission chain wound between the driving sprocket and the driven sprocket. The driving sprockets of the two chain transmission mechanisms are connected by a driving shaft 2, and the two driven sprockets are connected by a driven shaft 3. One end of the driving shaft is connected to a hydraulic motor 4, and the hydraulic motor is fixed on a motor seat 5. The hydraulic motor can drive the rotation of the driving shaft, thereby driving the two chain transmission mechanisms to work. The transmission chains of the two chain transmission mechanisms are fixed with multiple fixings, and the fixings adopt fixed tubes 6. Both ends of the fixed tubes are fixedly connected to the transmission chain, and multiple elastic teeth 7 are fixed on the fixed tubes.

[0034] The demolding plate 8 is arranged on the outer periphery of the top end of the chain transmission mechanism. The demolding plate adopts a first arc-shaped plate. The elastic teeth can extend to the outside of the demolding plate through the gaps between adjacent demolding plates. The shape of the demolding plate satisfies: along the movement direction of the elastic teeth, the distance that the top end of the elastic teeth can extend to the outside of the demolding plate gradually decreases. Finally, the elastic teeth are completely located on the inner side of the demolding plate. The maximum distance that the elastic teeth can extend to the outside of the demolding plate is greater than half of the length of the elastic teeth.

[0035] The upper end of the demolding plate is integrally connected with a second arc-shaped plate 9, and the demolding plate and the second arc-shaped plate form an annular plate structure, which can be made of steel plate.

The first plane connecting plate and the second plane connecting plate are connected by a third arc plate 12. The third arc plate adopts a semicircular ring structure and is made of steel plate. The elastic teeth can extend to the outside of the third arc plate through the gap between adjacent third arc plates, and the extending distance is greater than half of the length of the elastic teeth. The demolding plate, the second arc plate, the first plane connecting plate, the second plane connecting plate and the third arc plate together constitute a demolding assembly.

[0036] The annular plate structure formed by the stripping plate, the second arc-shaped plate and the third arc-shaped plate are all provided with a fixing plate 14, and the fixing plate is used to fix the stripping plate and the third arc-shaped plate to other structures.

[0041] Embodiment 3:

[0042] The present embodiment discloses a working method of a residual film recovery device: a chain transmission mechanism drives the elastic teeth to move through a fixed tube, the elastic teeth pick up the residual film 22 from the ground and transport it upward, when the elastic teeth pass through the film stripping plate, the distance from the top of the elastic teeth to the outside of the film stripping plate gradually decreases, and the movement of the elastic teeth causes the film stripping plate to push the residual film of the elastic teeth toward the outside of the top of the elastic teeth until the residual film is peeled off from the elastic teeth, and the peeled residual film can fall into the film box.

[0043] The speed regulating motor drives the stripping roller to rotate, and the stripping rubber plate can contact the outer side of the stripping plate to scrape off the residual film hanging on the outer side of the stripping plate, so that the residual film falls into the film box.

[0044] The residual film recovery device of this embodiment has a film stripping plate that can exert a large pushing force on the residual film in the upper and middle parts of the elastic teeth, effectively peeling the residual film from the elastic teeth, avoiding the problem that the residual film cannot be cleaned up in one go due to tight entanglement and dead knots. The film stripping effect is good, ensuring that there is no residual film on the elastic teeth, and ensuring the operating stability of the residual film recovery machine.
