Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rice transplanter floating plate mounting structure, more particularly to a rice transplanter double floating plate sensing control structure. BACKGROUND

[0002] The rice transplanter is a kind of agricultural machinery for transplanting rice seedlings into the rice field. When transplanting, a number of rice seedlings are first taken from the seedbed by a mechanical claw and transplanted into the soil of the field. In order to maintain a right angle between the seedbed and the ground, the front end of the mechanical claw must adopt an elliptical motion curve when moving. The motion is completed by a planetary mechanism of rotating or deforming gears, and the engine for forward movement can drive these motion mechanisms. The rice transplanter must be designed with non-slip wheels and floating plates when moving on the soil. Through sensing the ground condition by the floating plates, the mechanical claw can better transplant the rice seedlings into the soil.

[0003] In the existing rice transplanter, the floating plates located at the middle part of the whole device are in contact with the soil surface, and then the motion of the rice transplanter is adjusted. If the floating plates are single, the middle floating plate can be directly used for sensing. If the floating plates are double, in order to ensure the sensing effect, the floating plate located at the middle position is needed, which requires a separate sensing floating plate to be additionally arranged, resulting in a complex overall structure and increased cost.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0037] like Figures 1 to 10 The diagram illustrates a double-float sensing and control structure for a rice transplanter, comprising a crossbeam 1, longitudinal support brackets 3, float connecting crossbars 2, side floats 7, and a central float 70. Multiple longitudinal support brackets 3 are fixed at intervals on one side of the crossbeam 1. Each end of a longitudinal support bracket 3 is equipped with transplanting claws 6 via a transplanting box 5. The structure also includes a central float connecting rod 8, a float sensing rod 10, a pull-wire movable frame 11, a pull-wire connecting plate 12, and a sensing pull-wire 13. Two central floats 70 are respectively positioned below the two middle longitudinal support brackets 3. Multiple side floats 7 are positioned below the remaining longitudinal support brackets 3. The float connecting crossbar 2 is rotatably mounted below the longitudinal support brackets 3. The middle parts of the 7 and the central float plate 70 are respectively hinged to the float plate connecting crossbar 2. One end of the two middle central float plates 70 is respectively set at both ends of the middle float plate connecting rod 8 through ball bearings. One end of the float plate sensing rod 10 is connected to the middle part of the middle float plate connecting rod 8 through ball bearings, and the other end is fixed to the pull wire movable frame 11. The pull wire movable frame 11 is slidably connected to the pull wire connecting plate 12. The inner core of one end of the sensing pull wire 13 is fixed to the pull wire connecting plate 12, and the outer sleeve of the sensing pull wire 13 is stuck on the pull wire movable frame 11. The pull wire connecting plate 12 is hinged to the crossbeam 1, and the pull wire connecting plate 12 is movably connected to the float plate connecting crossbar 2 through the pull rod 14.

[0038] The long hole is arranged on the pull wire movable frame 11, the connecting shaft is arranged on the pull wire connecting plate 12, and the connecting shaft slides in the long hole. When the state of the two central floating plates 70 changes, the state change of the two central floating plates 70 is transmitted to the pull wire movable frame 11 through the central floating plate connecting rod 8 and the floating plate sensing rod 10, and then the position of the pull wire movable frame 11 and the pull wire connecting plate 12 changes, and further the inner core length of the sensing pull wire 13 changes, and then the rice transplanter senses the state change of the two central floating plates 70.

[0039] The two sides of the ball bearing 80 are respectively provided with a limiting sleeve 83, one end of the limiting sleeve 83 abuts against the ball bearing 80, and the other end abuts against the stop ring A 82 arranged on the central floating plate connecting rod 8. The central floating plate 70 is provided with a connecting support 90, the connecting support 90 is connected with one end of the central floating plate connecting rod 8 through the ball bearing 80, the central floating plate connecting rod 8 is further provided with a stop ring B 84 at a position close to the end, and the stop ring A 82 and the stop ring B 84 are further provided with a compression spring 81.

[0040] The one end of the support and the floating plate sensing rod 10 is provided with a hollow ring-shaped hinged seat, the hollow ring-shaped hinged seat and the ball bearing are further provided with a snap spring 85, when the central floating plate connecting rod 8 swings, one end of the limiting sleeve away from the ball bearing abuts against the inner wall of the hollow ring-shaped hinged seat, and the other end of the limiting sleeve close to the ball bearing abuts against the snap spring, the limiting sleeve can limit the rotation angle of the ball bearing, and avoid damage of the ball bearing due to too large rotation amplitude; when the two central floating plates are high and low, the compression springs of the two central floating plates are compressed, and the middle section of the central floating plate connecting rod 8 becomes long, so that the middle sensing point is always located at the middle position of the central floating plate connecting rod 8.

[0041] The ball bearing 80 outside the two ends and the middle part of the central floating plate connecting rod 8 is further provided with a ball bearing sleeve 9, and the outside of the ball bearing sleeve 9 is fixed with the central floating plate connecting rod 8 through the clamping ring 91. The floating plate connecting cross beam 2 is provided with a plurality of supporting rods 21, the side floating plate 7 and the central floating plate 70 are both provided with a hinged seat 74, and the supporting rod 21 is hinged with the hinged seat 74.

[0042] The other end of the central floating plate 70 is provided with a front limiting plate 73, and the end of the vertical support 3 is further fixed with a limiting block 31, and the front limiting plate 73 cooperates with the limiting block 31. The front limiting plate 73 and the limiting block 31 are both triangular. Since one end of the central floating plate is not limited, in order to prevent the collision between the central floating plate and the transplanter claw 6, the above limiting structure needs to be arranged to ensure the stable and efficient operation of the mechanism.

[0043] One end of the side floating plate 7 is provided with a rear limiting plate 71, and one end of the side floating plate 7 is further provided with a limiting guide rod 72, the cross beam 1 is fixed with a limiting frame 77, and the limiting guide rod 72 is arranged in the limiting frame 77. The other end of the side floating plate 7 is also provided with a front limiting plate 73, and the front limiting plate 73 directly cooperates with the bottom of the vertical support 3.

[0044] The limiting structure of the side float plate is different from that of the middle float plate. The side float plate can be equipped with limiting structures at both the front and rear, making the movement trajectory of the side float plate more stable. At the same time, due to the presence of the limiting structure near the crossbeam, the other end of the side float plate does not need to be equipped with a limiting block and can directly cooperate with the longitudinal extension bracket 3.

[0045] Both the side float 7 and the central float 70 have arc-shaped notches 75 on both sides near the rice planting claw 6 to avoid interference. The bottom of both the side float 7 and the central float 70 also has a through groove 76, with one end of the groove 76 being deeper than the other. The through groove in the middle of the float in this invention divides the bottom of the float into two parts, reducing resistance to movement and improving the stability of the float.

[0046] This invention connects two central floats together via a central float connecting rod. The two central floats jointly provide soil surface sensing information to the equipment. The central floats are connected to the central float connecting rod via ball bearings, and the central float sensing rod is also installed via ball bearings. The two central floats achieve integrated control, and a single float can provide 1 / 2 of the control quantity. This invention can be implemented with simple modifications to the existing float structure, resulting in a simple overall structure and good sensing effect.

[0047] In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0048] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
