Description

Technical Field

[0001] The present invention relates to the technical field of farmland residual film recovery, and in particular to a drum-type residual film picking and recovery device and a working method. Background Art

[0003] The drum-type residual film recycling machine is one of the widely used models, but the existing technology lacks the effective combination of agricultural machinery, agronomy and agricultural film, has a complex structure, and has problems such as large vibration, film entanglement and poor reliability. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a drum-type residual film picking and recovery device and a working method, which adopts a crank rocker mechanism to prevent the drum from being wrapped around the film during the picking operation, thereby ensuring the stability and quality of the machine operation.

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

[0006] A crank-rocker type residual film picking device comprises a roller, the roller is fixedly mounted on a crankshaft, the crankshaft can drive the roller to rotate, one end of several crank chains is fixedly arranged on the crankshaft, the other end of the crank chain is hinged to one end of a connecting rod, the other end of the connecting rod is connected with a spike tooth, the spike tooth is hinged to one end of a rocker, the other end of the rocker is fixedly connected to a frame hinge shaft, the frame hinge shaft is parallel to the crankshaft, both ends of the frame hinge shaft are rotatably connected to the end plates at both ends of the roller; entry and exit holes are opened in the circumferential direction of the roller, and the spike teeth can extend or retract into the entry and exit holes under the drive of external force.

[0007] In the above scheme, the roller includes a plurality of arc plates, the number of the arc plates is the same as the number of the frame hinge shafts, the plurality of arc plates form a circular structure, and the plurality of arc plates are provided with arc-shaped inlet and outlet holes.

[0008] In the above solution, the arc plates are detachably connected.

[0009] In the above scheme, there are several frame articulated shafts, which are distributed around the crank.

[0010] In the above solution, the crank is arranged at the center of the drum.

[0011] In the above solution, the spike teeth are threadedly connected to the connecting rod.

[0012] In the above solution, the phase difference between adjacent crank chains is 90°.

[0013] In the above solution, the arc plate is a structure with a convex middle and downwardly curved sides.

[0014] In the above solution, the connecting rod is connected to the connecting cover by bolts, and the connecting cover is rotatably connected to the crank chain by a bearing bush.

[0015] The working method of the crank-rocker type residual film picking device is that the drum makes a circular motion with the crankshaft, and at the same time, the rocker continuously swings relative to the drum under the drive of the crankshaft chain, so that each spike tooth extends out of or retracts into the drum through the inlet and outlet holes. After the spike tooth extends out of the drum, as the drum rotates, the spike tooth can hang the residual film on the spike tooth when entering the soil. As the drum continues to rotate, the spike tooth gradually retracts into the drum, and the residual film attached to the spike tooth falls off for collection; the crank-rocker mechanism composed of the rocker, the frame articulated shaft, the connecting rod and the crankshaft chain controls the extension and retraction of the spike tooth. The periodic extension and retraction of the spike tooth prevents the residual film from being entangled on the drum, thereby facilitating the collection of the residual film.

[0016] Beneficial effects:

[0017] The crank-rocker type residual film picking device provided by the present invention comprises a crank-rocker mechanism composed of a crankshaft, a connecting rod, a rocker and a frame hinge shaft. The crankshaft rotates a full circle to drive the rocker to swing back and forth, thereby realizing the extension or retraction of the spikes fixed on the crank-rocker mechanism. The extension and retraction of the spikes are realized by the crank-connecting rod mechanism, and the structure is simple, reliable and has good dynamic characteristics. The periodic extension or retraction of the spikes prevents the residual film from being entangled on the drum, ensuring that the machine can maintain efficient and reliable operation.

[0030] Combined with Figure 1-Figure 5As shown, a crank rocker type residual film picking device comprises a roller 1 and a picking assembly. The roller 1 is rotatably mounted on the residual film recycling machine frame via a crankshaft 14. The roller 1 is connected with a plurality of picking assemblies along the circumferential direction. The picking assembly comprises spike teeth 2, a rocker 11, a frame hinge shaft 12 and a connecting rod 13. One end of the connecting rod 13 is rotatably connected to the rocker 11, and the other end of the rocker 11 is fixedly connected to the frame hinge shaft 12. The frame hinge shaft 12 is parallel to the rotation center line of the crankshaft 14 and is arranged through a bearing. Mounted on the end plate 3, a plurality of rockers 11 are fixedly connected to the frame hinge shaft 12 along the axial direction, the spikes 2 are fixed to the connecting rod 13, and the outer circumference of the drum 1 is provided with inlet and outlet holes 15 corresponding to the spikes 2, respectively. The crankshaft 14 drives the drum 1 to make a circular motion, and at the same time, the crank chain 16 on the crankshaft 14, the rocker 11, the frame hinge shaft 12 and the connecting rod 13 form a crank rocker mechanism. The hinged rocker 11 swings back and forth under the action of the crankshaft 14, so that each spike 2 extends out or retracts the drum 1 through the inlet and outlet holes 15. Among them, the phase difference of adjacent crank chains 16 is 90°.

[0031] When in use, the crank rocker mechanism moves in a circle with the drum 1, and the rocker 11 is driven by the crank chain 16 driven by the crankshaft 14 and continuously swings relative to the drum 1, so that each spike 2 extends out of or retracts into the drum 1 through the inlet and outlet holes 15. After the spike 2 extends out of the drum 1, as the drum 1 rotates, the spike 2 can attach the residual film to the spike 2 when it enters the soil. As the drum 1 continues to rotate, the spike 2 gradually retracts into the drum 1, and the residual film attached to the spike 2 falls off and is collected. The crank rocker mechanism composed of the rocker 11, the frame hinge shaft 12, the connecting rod 13 and the crank chain 16 controls the extension and retraction of the spike 2, and has a simple structure and low cost. The periodic extension and retraction of the spike 2 prevents the residual film from being entangled on the drum 1, which facilitates the collection of the residual film.

[0032] In this embodiment, end plates 3 are provided at both ends of the drum 1, and a cylindrical structure is formed in the middle by several arc plates 4, wherein two end plates 3 are fixedly connected at both ends of the crankshaft 14, the number of arc plates 4 is equal to the number of the picking mechanisms and corresponds one to one, inlet and outlet holes 15 are provided on each arc plate 4, and the arc plates 4 are sequentially connected along the circumferential direction to form the main cylindrical structure of the drum 1, the loading and unloading process is simple, and it is convenient for machine inspection and maintenance.

[0033] In this embodiment, a plurality of reinforcing circular plates are fixedly connected to the crankshaft 14 between the two end plates 3 at intervals, and the inner side of each arc plate 4 is fixedly connected to the outer circumference of the reinforcing circular plate, thereby improving the strength of the drum 1 and ensuring the structural stability during operation. The two sides of the arc plate 4 are bent into a downwardly curved structure, and the middle is a convex structure, and each of the arc plates 4 is fixedly connected in sequence at the downwardly curved part to form the outer cylindrical surface of the drum.

[0034] In this embodiment, the spike teeth 2 are fixedly connected to the crank rocker mechanism by bolts and pins, so that the spike teeth can be easily disassembled and replaced.
