[0022] Please refer to Figures 1 - 5 , a rice transplanter, comprising a transplanter body 1, the transplanter body 1 includes a frame 2, a handrail 3 is fixedly installed on the rear side of the frame 2, and a seedling plate 5 and a sub-planting mechanism 6 are respectively installed on the front side of the frame 2.

[0023] Furthermore, it further includes a water spraying and wetting mechanism 4, the water spraying and wetting mechanism 4 is located on the top of the frame 2, the water spraying and wetting mechanism 4 includes a water storage tank 401 and a centrifugal pump 405, the water inlet end of the centrifugal pump 405 is communicated with a suction pipe 404, the water outlet end of the centrifugal pump 405 is installed with a transmission pipe 406, a regulating valve 411 and a flow rate sensor 412 are respectively sleeved and installed on the surface of the transmission pipe 406, one end of the transmission pipe 406 away from the centrifugal pump 405 is communicated with a hollow seat 408, spray holes 409 are penetrated and opened on the surface of the hollow seat 408, and a distance measuring sensor 410 is screwed and installed on one side of the hollow seat 408.

[0024] Furthermore, the bottom of the water storage tank 401 is fixedly connected with the top of the frame 2, and the bottom of the centrifugal pump 405 is bolted to the top of the frame 2.

[0025] Furthermore, the seedling plate 5 is located in front of the water storage tank 401, a sealing plate 402 is bolted to the top of the water storage tank 401, and a transparent window 403 is fixedly inlaid on the rear side of the water storage tank 401.

[0026] Furthermore, one end of the suction pipe 404 away from the centrifugal pump 405 penetrates through the water storage tank 401 and extends to the bottom of the inner cavity of the water storage tank 401, and the number of the transmission pipes 406 is two.

[0027] Furthermore, the water outlet end of the centrifugal pump 405 is communicated with a three-way pipe 407, and one end of the transmission pipe 406 is communicated with the three-way pipe 407.

[0028] Furthermore, an installation groove 7 is opened at the top of the surface of the seedling plate 5, and the surface of the hollow seat 408 is fixedly connected with the inner wall of the installation groove 7.

[0029] Furthermore, the number of spray holes 409 is several and they are evenly distributed on the hollow seat 408. An appropriate amount of water is preset in the water storage tank 401. The operator drives the rice transplanter body 1 to move by holding the handrail 3. The rice seedlings are laid on the seedling plate 5, and the transplanting operation is completed by the transplanting mechanism 6. When it is necessary to moisten the roots of the rice seedlings, the centrifugal pump 405 is controlled to work. The water in the water storage tank 401 is shunted and transmitted into the two transmission pipes 406 through the suction pipe 404 and the three-way pipe 407, and finally sprayed into the seedling plate 5 through the hollow seat 408 and the spray holes 409. The water flows downward along the inner wall of the seedling plate 5 to complete the moistening operation of multiple rice seedlings. In order to avoid excessive water affecting the rice seedlings and wasting water resources, the distance sensor 410 can be used to monitor the distance, judge the number of rice seedlings in the seedling plate 5, and judge the water flow rate in the transmission pipe 406 according to the detection signal of the flow rate sensor 412. Then the control valve 411 is controlled to work, and the opening degree of the valve in the control valve 411 is adjusted to adjust the water flow rate. When there are more rice seedlings in the seedling plate 5, the detection distance of the distance sensor 410 is short, the opening amplitude of the control valve 411 is large, and the water flow rate in the transmission pipe 406 is large. On the contrary, when there are fewer rice seedlings in the seedling plate 5, the detection distance of the distance sensor 410 is long, the opening amplitude of the control valve 411 is small, and the water flow rate in the transmission pipe 406 slows down.

[0030] Specifically, by setting the sealing plate 402, the top of the water storage tank 401 can be shielded and covered in the installation state to prevent the water in the water storage tank 401 from evaporating quickly. By setting the transparent window 403, it is convenient for the pusher at the rear to observe the liquid level height in the water storage tank 401. By setting the three-way pipe 407, the two transmission pipes 406 can be connected, and then the water can be shunted and transmitted into the two transmission pipes 406 to meet the water supply requirements for the rice seedlings in the two seedling plates 5. By setting the hollow seat 408 and the spray holes 409, the transmitted water can be evenly diffused and sprayed into the seedling plate 5, and the spraying uniformity is better. By setting the distance sensor 410, the placement position of the rice seedlings in the seedling plate 5 can be monitored in real time. By setting the flow rate sensor 412, the flow rate of the water transmitted through the transmission pipe 406 can be monitored in real time;

[0031] The transplanting mechanism 6 has the same structure and function as the transplanting components of the rice transplanter in the prior art, and will not be described herein.

[0032] In actual application, in order to promote the growth of the roots of rice seedlings, the clear water in the water storage tank 401 can be replaced with a rooting solution dissolved with rooting powder;

[0033] In actual application, the rice transplanter body 1 is equipped with a digital display controller, and the centrifugal pump 405, the control valve 411, the flow rate sensor 412 and the distance sensor 410 are all electrically connected to the digital display controller, and the detection signals of the flow rate sensor 412 and the distance sensor 410 are both displayed by the digital display controller.

[0034] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
