Description

Technical Field

[0001] This invention relates to the technical field of agricultural film residue recycling, and in particular to a conjugate cam-type film residue recycling machine picking device and its working method. Background Technology

[0002] The area of ​​farmland covered by plastic film mulching in my country has reached 300 million mu (approximately 20 million hectares). Plastic film mulching is widely used in cool regions to increase soil temperature, conserve water and soil, retain fertilizer, and improve fertilizer efficiency. While this technology has promoted agricultural development, the plastic film residues left in the soil are difficult to degrade, causing significant soil pollution and damage.

[0003] The drum-type residual film recycling machine is one of the most widely used models, but the existing technology lacks an effective combination of agricultural machinery, agronomy and agricultural film. The oscillation of the nail teeth is often controlled by springs to reset, which is complex in structure, has poor motion accuracy and poor durability and reliability of the device, and has problems such as film entanglement and poor reliability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a conjugate cam-type residual film recycling machine picking device and working method, which avoids film entanglement on the roller during the picking operation, ensuring the stability and quality of the machine operation.

[0005] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0006] A conjugate cam-type residual film recycling machine picking device includes a roller, which is fixedly mounted on a central shaft and rotatably mounted on a residual film recycling frame via the central shaft. Conjugate cams are installed on the residual film recycling frame and at both ends of the roller. The central shaft is parallel to a toothed shaft, on which several toothed pins are mounted. The roller extends from both ends of the toothed shaft and is rotatably connected to end plates at both ends of the roller. Both ends of the toothed shaft are connected to a roller connecting device, which includes a roller connecting boss, a first roller, and a second roller. The roller connecting boss is connected to the first and second rollers via roller connecting rocker arms on both sides. The first and second rollers slide in cooperation with the conjugate cams, thereby swinging back and forth relative to the roller, causing the toothed pins to extend or retract along the inlet and outlet holes opened on the roller.

[0007] In the above scheme, the conjugate cam includes a first cam and a second cam, and the first cam and the second cam are respectively in sliding engagement with the first roller and the second roller.

[0008] In the above scheme, the toothed shaft is connected to the roller connecting boss, and the toothed shaft drives the roller connecting boss to rotate together.

[0009] In the above scheme, the roller includes several arc plates, the number of which is the same as the number of nail tooth shafts. The several arc plates form a circumferential structure, and each of the several arc plates has an arc-shaped inlet and outlet hole.

[0010] In the above scheme, there are several spiked shafts, which are distributed around the central axis.

[0011] In the above scheme, the arc plate has a structure that is convex in the middle and bent downwards on both sides.

[0012] In the above scheme, the arc plates are detachably connected; adjacent arc plates are connected by a support plate.

[0013] In the above scheme, the nail teeth are connected to the nail tooth shaft by bolts.

[0014] In the above scheme, the conjugate cam is arranged symmetrically on both sides with the first roller and the second roller.

[0015] The working method of the conjugate cam-type residual film picking device is as follows: the roller connecting device moves in a circular motion with the drum. At the same time, under the combined action of the first roller, the second roller and the conjugate cam in the roller connecting device slidingly engage, the device swings back and forth relative to the drum, causing each nail tooth to extend or retract from the drum through the inlet and outlet holes. After the nail tooth extends out of the drum, the residual film can be attached to the nail tooth as the drum rotates. As the drum continues to rotate, the nail tooth gradually retracts into the drum, and the residual film attached to the nail tooth falls off for collection. The first roller, the second roller, the roller connecting rocker arm and the conjugate cam jointly control the nail tooth shaft to swing back and forth relative to the drum, thereby realizing the extension or retraction of the nail tooth fixedly connected to the nail tooth shaft. The periodic extension and retraction of the nail tooth prevents the residual film from getting tangled on the drum, facilitating the collection of the residual film.

[0016] Beneficial effects:

[0017] 1. In this invention, a conjugate cam mechanism is formed by a roller-connected rocker arm, a first roller, a second roller, a first cam, a second cam, and a frame. The roller-connected rocker arm rotates a full revolution with the drum, and simultaneously oscillates back and forth relative to the drum under the combined action of the first roller, the second roller, and the conjugate cam. This allows the nail teeth fixed on the nail tooth shaft to extend or retract from the inlet and outlet holes on the arc plate. The periodic extension or retraction of the nail teeth prevents residual film from tangling on the drum, ensuring that the machine can maintain efficient and reliable operation.

[0018] 2. The conjugate cam of the present invention includes a first cam and a second cam. The cam pair formed by the two rollers and the two cams causes the two rollers to swing, thereby controlling the extension or retraction of the pin teeth, thus making the structure more stable.

[0019] 3. The present invention has a simple and reliable structure, which avoids the film from getting tangled in the roller during the picking process, and ensures that the machine can maintain efficient and reliable operation. Attached Figure Description

[0031] The purpose of this invention is to provide a dual-roller conjugate cam type residual film picking device to solve the problems existing in the prior art, avoid film entanglement of the rollers during the picking process, and has a simple structure and high working efficiency.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Combined with appendix Figures 1-6 As shown, this embodiment provides a dual-roller conjugate cam type residual film picking device, including a roller 1, picking components and a conjugate cam. The roller 1 is rotatably mounted on the frame of the residual film recycling machine via a central shaft 11. The conjugate cam is fixedly connected to the frame of the residual film recycling machine. Multiple picking components are connected to the roller 1 along the circumferential direction. The picking components include nail teeth 2, a first roller 6, a second roller 7, a roller connecting device 10 and a nail tooth shaft 12. A roller connecting boss 13 and a roller connecting rocker arm 14 are fixedly connected to form the roller connecting device 10. The roller connecting device 10 is fixedly connected to the nail tooth shaft 12. The nail tooth shaft 12 is parallel to the central shaft 11 and rotatably connected to the roller 1. Multiple nail teeth 2 are fixedly connected to the nail tooth shaft 12 along the axial direction. The first roller 6 and the second roller 7 are rotatably connected to the roller connecting rocker arm 14. The outer circumferential surface of the roller 1 is provided with inlet and outlet holes 15 corresponding to each nail tooth 2. The roller connecting device 10 moves in a circular motion with the roller 1, and swings back and forth relative to the roller 1 under the combined action of the first roller 6, the second roller 7 and the conjugate cam, so that each nail tooth 2 extends out or retracts into the roller 1 through the inlet and outlet holes 15.

[0034] In use, the roller connecting device 10 moves in a circular motion with the roller 1, and simultaneously oscillates back and forth relative to the roller 1 under the combined action of the first roller 6, the second roller 7, and the conjugate cam. This causes each nail tooth 2 to extend or retract from the roller 1 through the inlet / outlet hole 15. After the nail tooth 2 extends out of the roller 1, it can attach the residual film to the nail tooth 2 as the roller 1 rotates. As the roller 1 continues to rotate, the nail tooth 2 gradually retracts into the roller 1, and the residual film attached to the nail tooth 2 falls off for collection. The nail tooth shaft 12 is oscillating back and forth relative to the roller 1 by the first roller 6, the second roller 7, the roller connecting rocker arm 14, and the conjugate cam, thereby realizing the extension or retraction of the nail tooth 2 fixedly connected to the nail tooth shaft 12. The structure is simple and the manufacturing cost is low. The periodic extension and retraction of the nail tooth 2 prevents the residual film from getting tangled on the roller 1 and facilitates the collection of the residual film.

[0035] In this embodiment, the roller 1 includes end plates 3, arc plates 4, support plates 5, and a central shaft 11. Two end plates 3 are fixedly connected to both ends of the central shaft 11. The number of arc plates 4 is equal to and corresponds one-to-one with the number of picking components. Inlet and outlet holes 15 are provided on each arc plate 4. The arc plates 4 and support plates 5 are alternately connected circumferentially to form the main cylindrical structure of the roller 1. Each support plate 5 is fixedly connected to two end plates 3. The central shaft 11 is fixedly connected to two end plates 3 and coaxially arranged. The arc plates 4 and support plates 5 form the cylindrical structure of the roller 1, simplifying the loading and unloading process and facilitating machine maintenance and repair.

[0036] In this embodiment, the arc plate 4 and the support plate 5 are alternately connected along the axial direction and fixedly connected to the end plate 3 by bolts to form the main structure of the roller 1. Several reinforcing circular plates are also fixedly connected at intervals on the central shaft 11 between the two end plates 3. The inner side of each support plate 5 is fixedly connected to the outer circumferential surface of each reinforcing circular plate to improve the strength of the roller 1 and ensure the structural stability during operation.

[0037] In this embodiment, the nail tooth 2 is fixedly connected to the nail tooth shaft 12 by bolts, which facilitates the disassembly and assembly of the nail tooth 2 and makes it easy to replace.

[0038] In this embodiment, the conjugate cam consists of two cams, an inner one and an outer one, which form a cam pair with the first roller 6 and the second roller 7 respectively. The conjugate cam is arranged symmetrically on both sides with the first roller 6 and the second roller 7.

[0039] In this embodiment, the conjugate cam is arranged symmetrically on both sides with the first roller 6 and the second roller 7 to improve the structural stability of the double roller conjugate cam type residual film picking device.
