Description

Technical Field

[0001] The present invention belongs to agricultural machinery, and mainly relates to a semi-mechanized operation cutting and baling machine applicable to crop harvesting in hilly small plots. Background Art

[0002] Hilly land is a type of land with a sloping surface, small plot area, and poor surface flatness. Existing large-scale agricultural harvesting machines are difficult to adapt to and meet the crop harvesting operations on such hilly plots. Therefore, until now, the crop harvesting operations on such hilly lands are mostly completed manually by manpower. The problems that must be solved are low labor efficiency, high labor intensity, and waste of human resources. Especially in recent years, with the urbanization transfer of rural young laborers to work in cities, the rural labor force has decreased significantly, and the lack of labor resources has further increased the operation cost of manual harvesting of hilly land crops and the decline of agricultural production economic benefits. Summary of the Invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, and in combination with the actual needs of crop harvesting operations in hilly areas, develop a bicycle-type cutting and baling machine for crop harvesting in hilly plots, so as to achieve the purposes of being able to adapt to and meet the strong crop harvesting ability in hilly plots, having good operation stability, improving the harvesting operation efficiency, reducing the labor intensity, saving human resources, and reducing the harvesting operation cost.

[0004] The object of the present invention is achieved as follows: A mechanism frame is fixedly installed on the front end of the bicycle frame in an inclined manner towards the rear side. N straw support and protection plates are fixedly installed at intervals from top to bottom in the middle part of the front side of the mechanism frame. A linear reciprocating cutter table assembly is fixedly installed on the bottom side of the mechanism frame. A left extrusion arc plate is fixedly installed on the left end of the mechanism frame from top to bottom to match the straw support and protection plates. An extrusion plate frame is installed on the right end of the mechanism frame in a laterally reciprocating movable manner. A right extrusion arc plate is fixedly installed on the extrusion plate frame symmetrically with the left extrusion arc plate. A one-way lead screw is axially and radially positioned and circumferentially rotatably supported and installed at the middle part of the mechanism frame, behind the position of the straw support and protection plates. The one-way lead screw is rotatably inserted and fitted with a threaded through hole on the extrusion plate frame. An extrusion driven gear and a relaxation driven gear are fixedly installed on the right end of the one-way lead screw. A motor and a battery are fixedly installed on the mechanism frame in a mutually connected manner. An extrusion driving gear and a relaxation driving gear are sequentially and rotatably sleeved on the motor shaft of the motor, and the rotation direction of the extrusion driving gear is opposite to the rotation direction of the relaxation driving gear. The extrusion driving gear is meshed and driven with the extrusion driven gear at a speed reduction ratio, and the relaxation driving gear is meshed and driven with the relaxation driven gear at a speed increase ratio. A guiding control seat, a T-shaped seat plate, and a vertically installed shaft are fixedly installed on the same side of the linear reciprocating cutter table assembly. A crank and a driven pulley are respectively fixedly installed on the upper and lower ends of the vertically installed shaft. A driving rod is inserted into the guiding control seat in a linearly movable manner. The inner end of the driving rod is hinged to the moving blade of the linear reciprocating cutter table assembly, and the outer end of the driving rod is hinged to the crank through a connecting rod. An A-axis and a B-axis are installed on the T-shaped seat plate perpendicularly and rotatably. A driven sprocket and a driving bevel gear are fixedly installed on the A-axis. A driven bevel gear and a driving pulley are fixedly installed on the B-axis. A secondary transmission chain is sleeved on the driving sprocket and the driven sprocket, and a transmission belt is sleeved on the driving pulley and the driven pulley. A locking rod is inserted into the outside of the right side of the mechanism frame in a vertically lockable and adjustable manner. The lower end of the locking rod is inserted and locked or disengaged from the teeth of the extrusion driven gear. Thus, a bicycle-type cutting and baling machine for crop harvesting in hilly areas is formed.

[0005] The present invention is a three-point support semi-mechanized small crop cutting and baling harvesting machine designed and developed according to the characteristics of hilly areas, with the characteristics of novel, unique, reasonable structure, simple and convenient operation, strong adaptability, good use stability, low labor intensity, saving human resources, and low operation cost, providing technical support for crop harvesting operations in hilly areas.

A driving sprocket 35 is fixedly installed on the crank pedal assembly 36. The main drive chain 32 is sleeved on the driving sprocket 35 and the follower sprocket 31. A follower universal ground wheel 34 is installed on the rear axle 33. A mechanism frame 3 is fixedly installed on the front end of the bicycle frame 1 in a vertically backward-inclined manner. N straw support and protection plates 39 are sequentially and intermittently fixedly installed from top to bottom at the middle position of the front side of the mechanism frame 3. The linear reciprocating cutter table assembly 13 is fixedly installed at the bottom side of the mechanism frame 3. A left extrusion arc plate 4 is fixedly installed on the left end of the mechanism frame 3 from top to bottom to match the straw support and protection plates 39. An extrusion plate frame 12 is installed on the right end of the mechanism frame 3 in a horizontally reciprocating movable manner. A right extrusion arc plate 37 is fixedly installed on the extrusion plate frame 12 symmetrically with the left extrusion arc plate 4. A one-way lead screw 5 is axially and radially positioned and circumferentially rotatably supported and installed at the middle position of the mechanism frame 3, behind the straw support and protection plates 39. The one-way lead screw 5 is rotationally inserted into a threaded through hole 12-1 on the extrusion plate frame 12. An extrusion driven gear 10 and a relaxation driven gear 11 are fixedly installed on the right end of the one-way lead screw 5. A motor 6 and a battery 40 are fixedly installed on the mechanism frame 3 in a mutually connected manner. An extrusion driving gear 8 and a relaxation driving gear 9 are sequentially and unidirectionally rotatably sleeved on the motor shaft of the motor 6, and the rotation direction of the extrusion driving gear 8 is opposite to the rotation direction of the relaxation driving gear 9. The extrusion driving gear 8 is meshed and driven with the extrusion driven gear 10 at a speed reduction ratio, and the relaxation driving gear 9 is meshed and driven with the relaxation driven gear 11 at a speed increase ratio. A guiding control seat 20, a T-shaped seat plate 26, and a vertical shaft 38 rotatably installed are respectively fixedly installed at the same side of the linear reciprocating cutter table assembly 13. A crank 19 and a driven pulley 21 are respectively fixedly installed at the upper and lower ends of the vertical shaft 38. A driving rod 17 is inserted into the guiding control seat 20 in a linearly movable manner. The inner end of the driving rod 17 is hinged to the moving blade 13-1 of the linear reciprocating cutter table assembly 13, and the outer end of the driving rod 17 is hinged to the crank 19 through a connecting rod 18. An A-axis 16 and a B-axis 24 are perpendicularly and rotatably installed on the T-shaped seat plate 26. A driven sprocket 14 and a driving bevel gear 15 are fixedly installed on the A-axis 16. A driven bevel gear 25 and a driving pulley 23 are fixedly installed on the B-axis 24. A secondary drive chain 27 is sleeved on the driving sprocket 28 and the driven sprocket 14. A transmission belt 22 is sleeved on the driving pulley 23 and the driven pulley 21.An insert locking rod 7 that can be locked and adjusted up and down on the outer side of the right side of the mechanism frame 3, and the lower end of the locking rod 7 is in an inserted locking fit or a disengaged inserted fit with the teeth of the extrusion driven gear 10.

[0016] During operation, the operator straddles the seat 2 and steps on the crank pedal assembly 36 with both feet to drive the drive sprocket 35 to rotate. The rotation of the drive sprocket 35 sequentially drives the main drive chain 32, the follower sprocket 31, and the front axle 30 to drive the drive ground wheel 29 to rotate, causing the whole machine to move forward. At the same time, the rotation of the ground driving sprocket 28 sequentially drives the secondary drive chain 27, the driven sprocket 14, the A-axis 16, the driving bevel gear 15, the driven bevel gear 25, the B-axis 24, the driving pulley 23, the transmission belt 22, the driven pulley 21, the vertical shaft 38, the crank 19, the connecting rod 18, and the driving rod 17 to push and pull the moving blade 13-1 of the linear reciprocating cutter header assembly 13 to perform a horizontal linear reciprocating motion, cutting off the crop straw standing on the surface of the hilly land. Under the impact of the forward driving force of the machine, the upper side of the straw tilts backward and accumulates in the front side of the straw support and protection plate 39, at the position between the left extrusion arc plate 4 and the right extrusion arc plate 37. When the straw accumulation reaches the limited amount, stop stepping on the crank pedal assembly 36 by manpower, and the machine stops moving forward. Start the motor 6 to rotate forward with the battery 40. The forward rotation power drives the one-way lead screw 5 to rotate through the extrusion drive gear 8 and the extrusion driven gear 10. At this time, the release drive gear 9 remains stationary. The rotating one-way lead screw 5 drives the right extrusion arc plate 37 to move horizontally inward through the extrusion plate frame 12, and squeezes the crop straw into a pile under the cooperation of the left extrusion arc plate 4. Then turn off the motor 6, move the locking rod 7 downward by hand, and circumferentially lock it through the inserted fit between the lower end of the locking rod 7 and the extrusion driven gear 10. Pass the binding rope through the gap between the upper and lower adjacent straw support and protection plates 39 by manpower, and then wind and bind it outside the crop straw pile. After binding, disengage the locking rod 7 from the inserted locking fit with the teeth of the extrusion driven gear 10, start the motor 6 to rotate in the reverse direction, and then drive the one-way lead screw 5 to rotate in the reverse direction through the release drive gear 9 and the release driven gear 11. Drive the right extrusion arc plate 37 to move horizontally to the side away from the left extrusion arc plate 4 through the extrusion plate frame 12, loosen and remove the bundled straw bale, and complete one operation. At this time, the extrusion drive gear 8 remains stationary. Operate in sequence and cycle to perform the operation.
