Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-8 In this embodiment of the utility model, a simple and portable double-row rice harvesting and shredding device includes...

[0035] The gathering frame 1 is used for gathering and rowing rice. The gathering frame 1 is fixedly connected to the push frame 2. A fixed knife holder 4 is bolted to the bottom side of the connection between the gathering frame 1 and the push frame 2, and a movable knife holder 5 is slidably connected to the inside of the fixed knife holder 4.

[0036] A crushing box 3 is fixed above the pusher 2; two crushing rollers 6 are installed inside the crushing box 3, and the two crushing rollers 6 are connected by two gears 14.

[0037] The crushing box 3 has a rectangular trough on the side away from the collecting frame 1 to facilitate the discharge of crushed straw.

[0038] By adopting the above technical solution, when harvesting the male parent rice, the two rows of male parent rice can be gathered together using the gathering frame 1. Then, the rice above the roots of the male parent rice is harvested under the alternating movement of the fixed blade holder 4 and the movable blade holder 5. After the harvested rice enters the crushing box 3, the two crushing rollers 6 crush the rice straw, which improves the crushing effect of the rice straw, so as to facilitate the subsequent return of straw to the field and also facilitate the degradation and decomposition of straw in the soil.

[0039] In this embodiment, the gathering frame 1 has three A-frames, and at least two wheels are installed on the upper surface of each A-frame. A toggle belt 8 is installed on the wheels. The outer side of the toggle belt 8 is provided with multiple teeth.

[0040] Furthermore, the wheel is also connected to a drive motor, which is located inside the front end of the A-frame (not shown in the figure).

[0041] By adopting the above technical solution, when harvesting the parent rice, the drive motor drives the rotating wheel to rotate, so that the conveyor belt 8 transports the rice. Since the conveyor belt 8 is set at an inclination, the harvested rice straw can be transported to the crushing box 3 for crushing.

[0042] In this embodiment, a protective shell 9 is provided above the toggle strap 8, and the protective shell 9 is fixedly connected to the A-frame.

[0043] The protective shell 9 prevents rice straw from getting tangled with the agitator belt 8, ensuring the normal operation of the equipment.

[0044] In this embodiment, a connecting rod 17 is movably connected to one end of the movable tool holder 5 near the gear 14 via a rotating shaft; the connecting rod 17 is connected to the eccentric wheel 16 via the rotating shaft.

[0045] The eccentric wheel 16 is mounted on the drive shaft, and the upper end of the drive shaft is connected to the crushing roller 6 through the bevel gear set 15; the drive shaft is also mounted to the collecting frame 1 through the seated bearing.

[0046] It should be noted that the fixed blade holder 4 is fixedly connected to the retracting frame 1, while the movable blade holder 5 is slidably connected inside the fixed blade holder 4. When the movable blade holder 5 moves laterally back and forth, the roots of the rice are cut off by the alternation between the movable blade holder 5 and the fixed blade holder 4. The specific driving principle of the lateral back and forth movement of the movable blade holder 5 is as follows:

[0047] When the crushing roller 6 rotates, the eccentric wheel 16 is driven to rotate through the bevel gear set 15. The eccentric wheel 16 pulls the movable blade holder 5 through the connecting rod 17, thereby realizing the lateral reciprocating movement of the movable blade holder 5. No additional drive components are required, the structure is reasonably designed, and the manufacturing cost is low.

[0048] It should be noted that the bevel gear set 15 is equipped with a protective cover on the outside to prevent it from getting tangled with rice straw; (Attached) Figure 1-8 The diagram is for a more intuitive display of the main components of the device; some protective covers are not shown.

[0049] In this embodiment, one end of one of the two crushing rollers 6 is also connected to the output shaft of the motor 7 via a coupling; the motor 7 is also fixedly connected to the motor base 11; the motor base 11 is fixed on the outside of the crushing box 3; a power distribution box 10 is also fixed on the outside of the crushing box 3, and the power distribution box 10 is located above the motor base 11.

[0050] It should be noted that the distribution box 10 can be equipped with either a circuit breaker or a storage battery; the motor 7 is selected as either an AC motor or a DC motor depending on the nature of the distribution box 10; if a storage battery is selected, the battery capacity should be chosen to meet the motor's usage requirements.

[0051] In this embodiment, wheels 12 are installed on the lower sides of both sides of the push frame 2 via a rotating shaft; two handles 13 are fixed on the upper part of the push frame 2.

[0052] When in use, pushing the two handles 13, in conjunction with the wheels 12, allows the equipment to move and harvest rice. Additionally, by pushing and pulling the handles 13 with the wheels 12 as the adjustment center, the height of the fixed blade holder 4 and the movable blade holder 5 relative to the ground can be adjusted, allowing for better contact with the ground during rice harvesting and reducing the height of the rice stubble.

[0053] The working principle of this utility model is as follows: By pushing the two handles 13, the equipment can be moved with the help of the wheels 12, thereby harvesting rice. In addition, by pushing and pulling the handles 13 with the wheels 12 as the adjustment center, the height of the fixed blade holder 4 and the movable blade holder 5 relative to the ground can be adjusted, so as to better fit the ground for harvesting rice; when the crushing roller 6 rotates, the eccentric wheel 16 is driven to rotate through the bevel gear set 15, and the eccentric wheel 16 pulls the movable blade holder 5 through the connecting rod 17, thereby realizing the lateral reciprocating movement of the movable blade holder 5.

[0054] When harvesting the male parent rice, the two rows of male parent rice can be gathered together using the gathering frame 1. Then, the rice above the roots of the male parent rice is harvested by the alternating movement of the fixed blade holder 4 and the movable blade holder 5. After the harvested rice enters the crushing box 3, the two crushing rollers 6 crush the rice straw, which improves the crushing effect of the rice straw, so as to facilitate the subsequent return of the straw to the field and also facilitate the degradation and decomposition of the straw in the soil.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0056] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
