Description

Technical Field

[0001] The utility model relates to the field of agricultural harvesting devices, in particular to a regenerated rice harvesting platform frame. Background Art

[0002] After the first season of rice is harvested, certain cultivation and management measures are taken to allow the rice stubble to sprout again, grow ears, and bloom and bear fruit, so that the second season can be harvested. This is called ratoon rice, also known as "one crop, two harvests". This model allows the rice field to be cultivated, raised, and planted at one time, and two seasons of rice can be harvested, which has many advantages. The existing ratoon rice production requires a lot of manpower to harvest in the first season, which is time-consuming and labor-intensive. During the harvesting process of ratoon rice, a major factor that affects the growth of ratoon rice in the later season is the height of the harvested rice stubble in different times and environments. This puts forward the necessity of making adaptive adjustments to the height of the ratoon rice harvesting platform frame; the harvesting height needs to be adjustable and controllable in real time.

[0003] In order to solve the above problems, a kind of detection tooling has emerged. For example, the Chinese utility model patent with announcement number CN209897650U discloses a regenerated rice harvesting platform frame, which includes an open rice shovel facing upward, a harvesting bin and side wall panels arranged on both sides of the harvesting bin; a cutting knife fixing port is arranged on both sides of the rice shovel; a rice combing device is arranged between the side wall panels; the rice combing device includes a rotating rod, comb teeth evenly spaced on the rotating rod and a turntable arranged at both ends of the rotating rod and on the outside of the side wall panels; a rice delivery port is arranged at the rear of the harvesting bin; the utility model device can harvest regenerated rice and adjust the rice stubble harvesting height at the same time. When the above-mentioned harvesting platform frame drives the rotating rod to rotate forward and backward, the tooth plate needs to reciprocate in the front-to-back direction to drive the comb teeth to clean the knotted rice on the rake in real time, but the problem of how to drive the tooth plate to efficiently reciprocate in the front-to-back direction has not been solved.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] Figure 1-2 The utility model provides a regenerated rice harvesting platform frame, including a rice shovel 1, a harvesting bin 2, a rotating rod 3, comb teeth 4, and two baffles 5, the two baffles 5 are fixed at the left and right ends of the harvesting bin 2, the rice shovel 1 is arranged at the front end of the harvesting bin 2, and the left and right sides of the rice shovel 1 are provided with cutter mounting openings 6, the rotating rod 3 is horizontally arranged, and its two ends are respectively rotatably connected with the two baffles 5, a plurality of comb teeth 4 are arranged on the rotating rod 3 at intervals, and a rice delivery opening 7 is opened at the rear end of the harvesting bin 2, and also includes a driving mechanism, the driving mechanism is arranged on one of the baffles 5, and its driving end is transmission-connected with the rotating rod 3 to drive the rotating rod 3 to rotate.

[0027] In this embodiment, the driving mechanism drives the rotating rod 3 to rotate forward and reverse, so that the multiple comb teeth 4 can make circular motion with the axis of the rotating rod 3 as the center. The multiple comb teeth 4 in motion can clean the knotted grains on the rake, which greatly improves the efficiency of cleaning the knotted grains on the rake.

[0028] Specifically, the driving mechanism includes a driving motor 81, a disc 82, a connecting rod 83, a sliding rod 84, a sliding sleeve 85, a rack plate 86, and a gear 87. The driving motor 81 is mounted on the harvesting bin 2 through a mounting seat, and its output shaft is horizontally arranged in the left-right direction and coaxially connected to the disc 82. One end of the connecting rod 83 is hinged to the edge of the disc 82, and the other end is hinged to the sliding rod 84. The sliding sleeve 85 is fixed on one of the baffles 5, and the sliding rod 84 slides horizontally in the sliding sleeve 85 in the front-back direction. One end of the rack plate 86 is fixedly connected to the sliding rod 84, and the gear 87 is coaxially connected to the rotating rod 3 and meshes with the rack plate 86.

[0029] When the driving motor 81 is started, the output torque of the driving motor 81 is transmitted to the disc 82 through a coupling. Since one end of the connecting rod 83 is hinged to the edge of the disc 82 and the other end is hinged to the sliding rod 84, and the sliding rod 84 slides horizontally in the sliding sleeve 85 in the front-back direction, the rotation of the disc 82 can drive the sliding rod 84 and the rack plate 86 to make a reciprocating motion in the front-back direction. Since the gear 87 meshes with the rack plate 86, when the rack plate 86 makes a reciprocating motion in the front-back direction, it can drive the gear 87 and the rotating rod 3 to rotate forward and backward, so that finally multiple comb teeth 4 can make a circular motion with the axis of the rotating rod 3 as the center. The multiple comb teeth 4 in motion can clean the knotted cereal grains on the harrow.

[0030] Preferably, as another embodiment of the present invention, on the basis of the Figure 1 shown embodiment, it further includes a lifting mechanism. The lifting mechanism includes a mounting plate 91, a plurality of telescopic cylinders 92, and a plurality of mounting members 93. The mounting plate 91 is fixed on the harvesting bin 2. The telescopic cylinders 92 are all arranged on the mounting plate 91, and their telescopic rods are vertically arranged and fixedly connected to the corresponding mounting members 93. A plurality of mounting holes are provided on the mounting members 93.

[0031] In this embodiment, as one implementation manner, the telescopic cylinders 92 can be installed at the bottom of the harvester through the mounting members 93. When the telescopic cylinders 92 (the telescopic cylinders 92 are hydraulic cylinders or electric cylinders) are started, the telescopic rods of the telescopic cylinders 92 can be telescoped to adjust the overall height of the frame, so as to adapt to the harvesting of ratooning rice at different times and in different environments.

[0032] Preferably, a baffle plate 10 is provided at the lower end of the grain delivery port 7.

[0033] The baffle plate 10 can prevent the cereal grains from falling below the frame when falling out of the grain delivery port 7, resulting in waste.

[0034] The working principle of the present invention:

[0035] The telescopic cylinder 92 can be installed at the bottom end of the harvester through the mounting member 93. When the telescopic cylinder 92 is started, the telescopic rod of the telescopic cylinder 92 can be extended and retracted to adjust the overall height of the frame, so as to adapt to the harvesting of ratooning rice at different times and in different environments. After the frame is installed at the lower end of the harvester, the designated cutter is installed at the cutter fixing 2. When the drive motor 81 is started, the output torque of the drive motor 81 is transmitted to the disc 82 through the coupling. Since one end of the connecting rod 83 is hinged to the edge of the disc 82 and the other end is hinged to the sliding rod 84, and the sliding rod 84 slides horizontally in the sliding sleeve 85 in the front-back direction, the rotation of the disc 82 can drive the sliding rod 84 and the rack plate 86 to make reciprocating motions in the front-back direction. Since the gear 87 meshes with the rack plate 86, when the rack plate 86 makes reciprocating motions in the front-back direction, it can drive the gear 87 and the rotating rod 3 to rotate forward and backward, and finally the multiple comb teeth 4 can make circular motions around the axis of the rotating rod 3. The multiple comb teeth 4 in motion can clean the knotted grains on the harrow.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
