Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural harvesters, and relates to a rolling harvesting device and method for Houttuynia cordata in wetlands. Background Art

[0002] The roots, stems and leaves of Houttuynia cordata can all be eaten and used as medicine, and the main planting methods are divided into dryland planting and wetland planting.

[0003] During the growth of dryland Houttuynia cordata, its roots have a certain pattern, and the roots of adjacent two plants of Houttuynia cordata are not easily entangled, and the roots are easily separated during collection. Since wetland Houttuynia cordata grows in shallow water, its rhizomes penetrate into the shallow water layer and the mud layer, resulting in relatively developed roots connected to the rhizomes, and the rhizomes and roots between adjacent two plants are intertwined with each other, forming an overall "root blanket" laid in the shallow water layer.

[0004] When harvesting dryland Houttuynia cordata, it is usually not necessary to cut the stems and leaves above the ground surface first, and it can be directly dug; the digging is usually carried out by manual excavation or mechanical rake excavation; when harvesting in wetlands, the rhizomes in the deep part of the mud layer need to be cut off first, and the rhizomes in the shallow part are retained to form a "root blanket". At present, it is completely impossible to harvest wetland Houttuynia cordata in the same way as dryland Houttuynia cordata. Summary of the Invention

The operating table is a mesh plate structure with multiple mesh holes, and on one end of the operating table adjacent to the direction rod, there is an avoidance opening.

[0014] The described rolling coiling mechanism includes a rotating housing, a rotating motor, a rolling shaft, rolling nails, a connecting column, and a cross connecting plate. At one end of the rotating housing, there is a connecting column which is inserted into the connecting hole of the transfer folding frame. The rotating motor is installed on one side of the rotating housing, and the output end of the rotating motor passes through the rotating housing and is connected to the cross connecting plate. The cross connecting plate has multiple through holes into which the rolling shaft is inserted, and there are multiple rolling nails on the rolling shaft.

[0015] The usage method of the wetland houttuynia cordata rolling harvesting device as described above includes the following steps: S1. Feeding: Place the "root system blanket" on the rolling coiling mechanism, and the rolling nails pass through the "root system blanket" to prevent the "root system blanket" from slipping. S2. Rolling coiling: The driving wheel rotates to drive the entire harvesting device forward. At the same time, the rotating motor drives the cross connecting plate and drives the rolling shaft to rotate to convey the "root system blanket" along the sieve towards the operating table. In this step, the cutting knife moves forward synchronously with the harvesting device and cuts the "root system blanket" to prevent the width of the "root system blanket" from exceeding the width of the rolling coiling mechanism. In this step, the "root system blanket" conveyed onto the operating table is manually rolled into bundles and then unloaded. S3. Distance adjustment: The controller controls the lifting mechanism of the vehicle frame to lift and lower. The lifting mechanism drives the transfer frame to perform vertical lifting and lowering. The fixed frame and the folding frame move within a range of 90° in angle through the reciprocating hydraulic cylinder and the elastic member. In this step, the adjustment of the angle is to prevent the "root system blanket" from being torn during the coiling process. S4. U-turn: When the harvesting device reaches the other end of the paddy field, the lifting mechanism drives the transfer frame to lift. The support mechanism in the operating table slides along the hollow tube and descends accordingly, and the pin is inserted through the pin holes on the hollow tube and the support column. The lifting mechanism drives the transfer frame to lower, making the driving wheel and the auxiliary wheel suspended. Then, the entire harvesting device is manually pushed to rotate 360° with the support column as the fulcrum to turn the harvesting device to the required direction. After that, the lifting mechanism drives the transfer frame to lift and reset again. S5. Steering: During the walking process of the harvesting device, apply a lateral thrust to the side of the direction rod to deflect the driving wheel, thereby steering the harvesting device. S6. Leveling: When the harvesting device is in an inclined state, the hydraulic rod drives the telescopic column to slide along the sleeve, driving the auxiliary wheel to lift and lower to adjust the overall balance of the harvesting device.

[0016] The main beneficial effects of the present invention are as follows: It is nested with the vehicle frame through a lifting mechanism and connected to the transfer rack, enabling the overall device to achieve harvesting during forward movement, improving convenience and efficiency at the same time.

[0017] One side of the beam frame is connected to the fuel tank and the other side is connected to the telescopic column, enabling the auxiliary wheel to be telescopically adjusted to always be horizontal with one side of the driving wheel, ensuring the stability of the device during operation.

[0018] It is nested with the framework through a lifting mechanism and connected to the transfer rack, enabling the hydraulic telescopic cylinder to telescopically control the articulated frame to drive the telescopic frame to lift, and the transfer rack to lift and lower along with the telescopic frame.

[0019] It is connected to the transfer rack through an operating platform, enabling the support mechanism to be installed in the operating platform. When the device gets stuck in the mud, the lifting mechanism lifts and drives the transfer rack to rise, and the support mechanism supports the overall device to enable manual rotation to help the device turn and reverse.

[0020] Through the cooperation of the reciprocating hydraulic cylinder and the elastic member with the fixed frame and the folding frame, the range of the included angle is increased or decreased, enabling the "root system blanket" to avoid being disconnected due to excessive tension during backward transmission, ensuring the quality of harvesting and coiling.

[0021] The rolling shaft in the coiling device rotates with the rotating shaft to roll and transmit the "root system blanket" and coil it, improving efficiency and ensuring the quality of harvesting the "root system blanket" at the same time.

[0022] Since the width of the "root system blanket" in the planted wetland is inconsistent with the width of the rolling shaft, by placing the overall device in the wetland and moving forward, the cutting knife provided at the bottom of the fixed frame is used in cooperation to cut out a "root system blanket" with the same width as the rolling shaft, and then perform backward transmission and harvesting.

Two driving wheels 15 are respectively connected to both ends of the fuel tank 12. One of the driving wheels 15 is connected to the steering rod 17. The controller 6 is connected to the beam frame 11. The power system 5 is located on one side of the fuel tank 12. The hydraulic rod 14, the driving wheels 15, and the controller 6 are all connected to the power system 5. The beam frame 11 is an inverted U-shaped structure with an opening facing downwards, including hollow tubes 19 vertically connected to both ends of the cross beam of the beam frame 11. A pipe sleeve 18 is provided on one side of one of the hollow tubes 19. A chute hole and a hinge hole are provided on the cross beam. The telescopic column 13 is controlled by the hydraulic rod 14 to rise and fall, so that the auxiliary wheel 16 and the driving wheels 15 are always horizontal during movement. The steering rod 17 controls the driving wheels 15 to deflect to achieve steering, improving the direction control of the device during movement.

[0037] Preferably, hydraulic oil is stored in the fuel tank 12. The driving wheels 15 are hydraulic wheels. The power system 5 is an engine. The engine is connected to the hydraulic system. The engine provides pressure for the hydraulic system. The fuel tank 12 is communicated with the hydraulic system, the driving wheels 15, the hydraulic telescopic cylinder 23, the reciprocating hydraulic cylinder 36, and the hydraulic rod 14. The rotary motor 42 is electrically connected to the power system 5.

[0038] Furthermore, the lifting mechanism 2 includes a telescopic frame 21, a hinge frame 22, and a hydraulic telescopic cylinder 23. The telescopic frame 21 is an inverted U-shaped structure with an opening facing downwards, including vertical beams vertically connected to both ends of the cross beam of the lifting mechanism 2. A chute hole and a hinge hole are provided on the cross beam. The hinge frame 22 is an X-cross five-point hinge structure. Two of the hinge points cooperate with the chute and hinge holes on the cross beam of the lifting mechanism 2, and the other two hinge points cooperate with the chute and hinge holes on the cross beam of the beam frame 11. Both ends of the hydraulic telescopic cylinder 23 are respectively connected to two hinge points on the hinge frame 22. The hydraulic telescopic cylinder 23 drives the hinge frame 22 to drive the telescopic frame 21 to slide up and down along the pipe sleeve 18 of the frame 1. By nesting the telescopic frame 21 with the skeleton 11, the hydraulic telescopic cylinder 23 drives the movable frame 22 to fold, so that the telescopic frame 21 and the transfer frame 3 are lifted and lowered, and the height of the cutting knife 313 in the transfer frame 3 and the "root system blanket" can be adjusted to adapt to "root system blankets" of different thicknesses.

[0039] Furthermore, the transfer rack 3 includes a fixed rack 31, a transfer folding rack 32, an operating table 33, a connecting member 34, an elastic member 35, a reciprocating hydraulic cylinder 36, and a connecting plate 37. The fixed rack 31 and the transfer folding rack 32 are engaged through a connecting seat 311. One end of the operating table 33 is connected to the connecting seat 311. The pin 71 of the support mechanism 7 passes through the hollow tube 331 of the operating table 33. The connecting member 34 is connected to the bushing 312 inside the fixed rack 31. The two ends of the elastic member 35 and the two ends of the connecting plate 37 are respectively connected to the ear plate 325 of the folding rack 321 and the ear seat 342 of the connecting member 34. One end of the reciprocating hydraulic cylinder 36 is connected to the fixed rack 31, and the other end of the reciprocating hydraulic cylinder 36 is connected to the ear seat 342. The support mechanism 7 includes a support plate connected to a support column, and a plurality of pin holes arranged in a modulus are provided on the support column. The pin 71 cooperates with the pin holes. By engaging the fixed rack 31 and the transfer folding rack 32, the included angle between the two can be controlled. When the rhizome of the "root system blanket" is short, the included angle becomes smaller; when the rhizome is long, the included angle becomes larger, avoiding breakage caused by uneven stress on the "root system blanket" due to different thicknesses and inconsistent compactness of the "root system blanket". The operating table 33 provides an operating space for manual operation. At the same time, the coiled "root system blanket" can be placed on the operating table 33 for manual coiling and cutting.

[0040] Furthermore, the fixed rack 31 includes a connecting seat 311, a bushing 312, a cutting knife 313, and a sliding rod 314. A connecting seat 311 is provided at one end of the fixed rack 31. The two ends of the connecting rod 341 of the connecting member 34 are inserted into the bushing 312 inside the fixed rack 31. One cutting knife 313 is slidably engaged through the sliding rod 314 at the lower end of the cross beam of the fixed rack 31, and the other cutting knife 313 is located on the side of the fixed rack 31. Pushing the cutting knife 313 to slide along the sliding rod 314 facilitates adjusting the cutting width of the "root system blanket".

[0041] Furthermore, the transfer folding rack 32 includes a folding rack 321, a screen 322, a separating column 323, a connecting hole 324, and an ear plate 325. The screen 322 is connected in parallel to the upper end surface of the folding rack 321. Ear plates 325 are symmetrically provided on the cross beam of the folding rack 321. The folding rack 321 is of a U-shaped structure, and a plurality of separating columns 323 are provided in the opening direction. A connecting hole 324 is provided at one end of the folding rack 321. The separating column 323 separates the "root system blanket" from the rolling shaft 43 during the rolling process, and at the same time supports the "root system blanket" to prevent collapse. The screen 322 sifts the muddy water of the "root system blanket" to improve the overall quality.

[0042] Furthermore, the connecting member 34 includes a connecting rod 341 and an ear seat 342. Ear seats 342 are symmetrically provided on the connecting rod 341. The two ends of the connecting rod 341 are connected to the bushing 312 inside the fixed rack 31. When the folding rack 321 moves through the reciprocating hydraulic cylinder 36, the fixed rack 31 remains horizontal, and the direction of the cutting knife 313 at the lower end of the fixed rack 31 remains unchanged for cutting.

[0043] Furthermore, the operation platform 33 includes a hollow tube 331 and mesh holes 332. A hollow tube 331 is provided on one side of the operation platform 33 close to the fixing frame 31, and a pin hole is provided on one side of the hollow tube 331. The operation platform 33 is of a mesh plate structure with a plurality of mesh holes 332 provided thereon, and an avoidance opening is provided at one end of the operation platform 33 close to the direction rod 17. This enables the "root system blanket" transmitted to the operation platform 33 to be sieved again to prevent excessive soil from entering the "root system blanket". At the same time, when the driving wheel 15 is controlled by the direction rod 17 to rotate, it passes through the avoidance opening to avoid touching the operation platform 33, restricting its rotation direction and improving the overall convenience.

[0044] Furthermore, the rolling and coiling mechanism 4 includes a rotating housing 41, a rotating motor 42, a rolling shaft 43, rolling nails 44, a connecting column 45, and a cross connecting plate 46. A connecting column 45 is provided at one end of the rotating housing 41 and is inserted into the connecting hole 324 of the transfer folding frame 32. The rotating motor 42 is installed on one side of the rotating housing 41, and the output end of the rotating motor 42 passes through the rotating housing 41 and is connected to the cross connecting plate 46. The cross connecting plate 46 is provided with a plurality of through holes into which the rolling shaft 43 is inserted, and a plurality of rolling nails 44 are provided on the rolling shaft 43. When the "root system blanket" is placed on the rolling shaft 43 through the rolling nails 44, it can prevent sliding and avoid the "root system blanket" from slipping, improving the overall transmission efficiency during rolling.

[0045] Furthermore, the usage method of the above-mentioned wetland houttuynia cordata rolling harvesting device includes the following steps: S1, feeding: Place the "root system blanket" on the rolling and coiling mechanism 4, and the rolling nails 44 pass through the "root system blanket" to prevent the "root system blanket" from slipping. S2, rolling and coiling: The driving wheel 15 rotates to drive the entire harvesting device to move forward. At the same time, the rotating motor 42 drives the cross connecting plate 46 and drives the rolling shaft 43 to rotate to convey the "root system blanket" along the screen 322 towards the operation platform 33. In this step, the cutting knife 313 moves forward synchronously with the harvesting device and cuts the "root system blanket" to prevent the width of the "root system blanket" from exceeding the width of the rolling and coiling mechanism 4. In this step, the "root system blanket" conveyed to the operation platform 33 is manually rolled into bundles and then unloaded. S3, distance adjustment: The controller 6 controls the lifting mechanism 2 of the vehicle frame 1 to lift or lower. The lifting mechanism 2 drives the transfer frame 3 to perform vertical lifting or lowering. The fixing frame 31 and the folding frame 321 move within an angle range of 90° through the reciprocating hydraulic cylinder 36 and the elastic member 35. In this step, the adjustment of the angle is to prevent the "root system blanket" from being torn during the coiling process. S4. U-turn. When the harvesting device reaches the other end of the paddy field, the lifting mechanism 2 drives the transfer frame 3 to lift. The support mechanism 7 in the operating platform 33 slides along the hollow tube 331 and descends accordingly, and inserts the bolt 71 through the pin holes on the hollow tube 331 and the support column. The lifting mechanism 2 drives the transfer frame 3 to descend, making the driving wheel 15 and the auxiliary wheel 16 suspended. Then, manually push the whole harvesting device to rotate around the support column, rotate 360°, so that the harvesting device faces the required direction. After that, the lifting mechanism 2 drives the transfer frame 3 to lift and reset again. S5. Steering. During the walking process of the harvesting device, apply a lateral thrust to the side of the direction rod 17 to deflect the driving wheel 15, so as to steer the harvesting device. S6. Leveling. When the harvesting device is in an inclined state, the hydraulic rod 14 drives the telescopic column 13 to slide along the sleeve 18, driving the auxiliary wheel 16 to lift and lower to adjust the overall balance of the harvesting device.

[0046] In the above method, during the process of winding up the "root system blanket", through the control of the included angle, when the pulling force is too large, the elastic member 35 and the reciprocating hydraulic cylinder 36 reduce the included angle, ensuring that the "root system blanket" is not easily pulled off. At the same time, the rolling winding mechanism 4 rolls to convey the "root system blanket" backward. Moreover, the lifting mechanism 2 drives the transfer frame 3 to lift and lower, enabling the operating platform 33 to cooperate with the support mechanism 7 to complete a U-turn and steering, improving the overall convenience and controllability of the harvesting device.
