Description

Technical Field

[0001] The utility model relates to the technical field of rice seedling cultivation, in particular to a rice seedling cultivation water-saving cultivation device. Background Art

[0002] Rice seedling cultivation is an important part of the rice planting process to ensure the healthy growth and high yield of the seedlings. During the seedling cultivation period, attention should be paid to management measures such as fertilization, irrigation, weeding, and pest control to ensure the healthy growth of the seedlings. During the seedling cultivation process, it is necessary to fully control the amount of irrigation water to keep the soil moist and avoid drought or waterlogging of the seedlings.

[0003] However, the prior art has the following defects:

[0004] Generally, seedling raising equipment controls the amount of water irrigated to the seedling raising tray by controlling the water output of the valve nozzle. However, the growth of each bunch of seedlings is different, and the excess water that cannot be absorbed will accumulate at the bottom of the seedling raising tray, causing the roots of the seedlings to rot. In order to avoid rot, some farmers will poke holes at the bottom of the seedling raising tray so that the excess water can flow out of the seedling raising tray, but this method is more wasteful of water resources. Summary of the invention

[0005] In order to solve the technical problem of wasting water resources during irrigation, the utility model provides a rice seedling raising and water-saving cultivation device.

[0006] The utility model adopts the following technical scheme to achieve: a rice seedling raising and water-saving cultivation device.

[0007] It comprises a bracket, a motor is arranged in the bracket, and a rotating rod is arranged at the output end of the motor;

[0008] A rotating irrigation mechanism, which includes two discs, a limiting groove, a seedling tray, a water pumping pipe, a spray head, a stabilizing unit and a sliding unit. One end of one of the discs is arranged on the rotating rod, and one end of the other disc is connected to the stabilizing unit. The adjacent ends of the two discs are provided with a placing disc through a sliding unit. The placing disc is provided with a limiting groove for placing the seedling tray. The water pumping pipe is arranged on a bracket, and multiple spray heads are arranged on the water pumping pipe.

[0009] A rotating drainage mechanism, the rotating drainage mechanism includes an interface, a water flow trough, a filter box and an elastic unit, the two interfaces are fixed on the bracket, the water flow trough is opened on the bracket, and both ends of the water flow trough are connected to the interface to form channel 2, one end of the filter box is provided with a fixed pipe connected to channel 2, and one end of the water pumping pipe is connected to the filter box.

[0010] Through the above technical solution, the motor can drive the disc to rotate, thereby causing the disc to rotate, and because the two discs are connected through the placement disc, the other disc is also driven to rotate. Therefore, the seedling tray can be rotated to be located below the spray head for irrigation and located on one side of the interface for drainage.

[0011] The rice seedlings can be planted in the seedling tray under the action of the rotating irrigation mechanism, and the irrigation work can be realized by cooperating with the spray head to spray water. At the same time, it is relatively space-saving, and a large number of rice seedlings can be cultivated to increase the output value. The limit groove can place the seedling tray more stably in the placement tray. In addition, a weight block is provided at one end of the placement tray away from the limit groove to ensure that when the disc rotates, the seedling tray can always be located directly above and will not tip over.

[0012] The excess water in the seedling tray can be discharged by rotating the drainage mechanism, thereby improving the utilization rate of water.

[0013] As a further improvement of the above solution, the stabilizing unit includes a rotating plate and a rotating groove, the rotating groove is opened on the bracket, one end of the rotating plate slides on the rotating groove, and the other end of the rotating plate is fixedly connected to the disc.

[0014] Through the above technical solution, the rotating plate rotates in the rotating groove, so that the disc not connected to the rotating rod can also rotate smoothly, thereby improving the overall stability of the device.

[0015] As a further improvement of the above scheme, the sliding unit includes a limiting cylinder, a slot, a slide rail and a water storage unit, and the plurality of limiting cylinders are symmetrically fixed at an adjacent end of the disc. The slot is opened on the disc and connected to the inner cavity of the limiting cylinder to form a channel three for the placement disc to pass through, and the two ends of the placement disc pass through the channel three and are located at an end of the disc away from each other. The slide rail is fixed on the placement disc, and the limiting cylinder is provided with a track for the slide rail to slide.

[0016] According to the above technical solution, the placement tray will also rotate to keep the seedling tray from tipping over and always facing upwards when the disc rotates, so that the slide rail can rotate in the track, thus ensuring that the placement tray can rotate and the stability of the placement tray is ensured.

[0017] As a further improvement of the above scheme, the water storage unit includes a lifting block, a flow hole and a water guide groove. A plurality of the lifting blocks are fixed in the limiting groove at equal distances, a plurality of the flow holes are opened at equal distances at the bottom of the seedling tray, and the water guide groove is opened in the placing tray and connected to the limiting groove to form channel one.

[0018] Through the above technical solution, the bottom of the seedling tray and the limiting groove can be prevented from contacting by setting multiple lifting blocks, so that the water inside the limiting groove can erode into the seedling tray, and then the rice seedlings will rot. At the same time, multiple flow holes can ensure that the soil water in the seedling tray can be discharged when there is a lot of water, so that each rice seedling can absorb water according to its own growth state, so that it can grow better. And the channel formed by the limiting groove and the water guide groove improves the convenience of subsequent drainage.

[0019] As a further improvement of the above scheme, the elastic unit includes a fixed plate, a spring groove, a spring, a baffle, a lifting plate and a contact unit, the fixed plate is fixed to the two ends of the placement plate extending from channel three, and the spring groove is opened on the fixed plate, one end of the spring is fixed in the spring groove, and the other end of the spring is connected to the baffle, and the lifting plate is fixed to the end of the baffle away from the placement plate.

[0020] Through the above technical solution, the spring groove can be set to drive the sealing gasket on the baffle plate to contact the water guide groove again, so as to seal the water guide groove and prevent water from flowing out of the water guide groove. The spring groove is provided for the baffle plate to move, and the lifting plate is provided so that the lifting plate can contact the interface to perform drainage work.

[0021] As a further improvement of the above solution, the contact unit includes balls, a plurality of the balls are rolled and embedded on the lifting plate, and a sealing gasket is provided at one end of the baffle plate close to the placement plate to contact the water guide groove.

[0022] Through the above technical solution, the plurality of balls are provided, so that the lifting plate is smoother when in contact with the interface, and the friction force generated by the balls and the interface is also smaller, thereby extending the service life of the device. The provided sealing pad can prevent water leakage in the water guide groove.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0032] Example 1

[0033] Please combine Figure 1-4 A rice seedling water-saving cultivation device of this embodiment includes a bracket 1, a motor 2 is arranged in the bracket 1, and a rotating rod 3 is arranged at the output end of the motor 2;

[0034] The rotating irrigation mechanism includes two discs 4, a limiting groove 9, a seedling tray 11, a water pumping pipe 23, a spraying head 24, a stabilizing unit and a sliding unit. One end of one disc 4 is arranged on the rotating rod 3, and one end of the other disc 4 is connected to the stabilizing unit. The adjacent ends of the two discs 4 are provided with a placing disc 8 through a sliding unit. The placing disc 8 is provided with a limiting groove 9 for placing the seedling tray 11. The water pumping pipe 23 is arranged on the bracket 1, and multiple spraying heads 24 are arranged on the water pumping pipe 23.

[0035] The limiting groove 9 is conical in shape, so that the center of the cone is located in the middle of the limiting groove 9 and is connected to the water guide groove 13, so that the water in the limiting groove 9 can flow into the water guide groove 13 to the greatest extent. And because the limiting groove 9 is conical, the height of each lifting block 10 is different, but the horizontal height of the top of the lifting block 10 is on the same straight line to ensure that the seedling tray 11 can be placed stably.

[0036] The rotating drainage mechanism includes an interface 20, a water flow trough 21, a filter box 22 and an elastic unit. The two interfaces 20 are fixed on the bracket 1. The water flow trough 21 is opened on the bracket 1, and both ends of the water flow trough 21 are connected to the interface 20 to form a channel 2. One end of the filter box 22 is provided with a fixed pipe connected to the channel 2, and one end of the water suction pipe 23 is connected to the filter box 22.

[0037] A rubber pad is provided at one end of the interface 20 close to the disc 4, so that when the disc 4 contacts the rubber pad and the ball 19 moves to the peak of the interface 20, the rubber pad can guide the water in the water guide groove 13 when draining water, so that the water in the water guide groove 13 can flow into the interface 20 as much as possible.

[0038] The stabilizing unit includes a rotating plate 25 and a rotating groove 26 . The rotating groove 26 is provided on the bracket 1 . One end of the rotating plate 25 slides on the rotating groove 26 , and the other end of the rotating plate 25 is fixedly connected to the disc 4 .

[0039] The sliding unit includes a limiting cylinder 5, a slot 6, a slide rail 7 and a water storage unit. Multiple limiting cylinders 5 are symmetrically fixed at the adjacent end of the disc 4. The slot 6 is opened on the disc 4 and is connected to the inner cavity of the limiting cylinder 5 to form a channel three for the placement disc 8 to pass through, and the two ends of the placement disc 8 pass through the channel three and are located at the end of the disc 4 away from each other. The slide rail 7 is fixed on the placement disc 8, and the limiting cylinder 5 is provided with a track for the slide rail 7 to slide.

[0040] The water storage unit includes a lifting block 10, a flow hole 12 and a water guide groove 13. Multiple lifting blocks 10 are fixed in the limiting groove 9 at equal distances. Multiple flow holes 12 are opened at the bottom of the seedling tray 11 at equal distances. The water guide groove 13 is opened in the placing tray 8 and connected with the limiting groove 9 to form channel 1.

[0041] The implementation principle of a rice seedling water-saving cultivation device in the present application is as follows: first, multiple seedling trays 11 are placed in the limiting grooves 9 in sequence, and placed on two adjacent lifting blocks 10, so that the bottom of the seedling tray 11 does not contact the limiting grooves 9, and then soil and germinated rice seedlings are placed in the seedling tray 11. When it is necessary to irrigate the rice seedlings in the seedling tray 11, start the motor 2 so that the motor 2 drives the rotating rod 3 to rotate, and then drives the disc 4 to rotate. The rotating plate 25 slides in the rotating groove 26. When the disc 4 rotates, the slide rail 7 slides in the track opened in the limiting cylinder 5, so that the heads of the rice seedlings on the seedling tray 11 are always located at the top. When one of the placement trays 8 is rotated by the disc 4 to the position directly below the spray head 24, the valve on one side of the water pumping pipe 23 is opened (the irrigation time can be adjusted according to the conditions of the rice seedlings at different stages) to control the water inlet pipe (not shown) connected to one side of the water pumping pipe 23 to spray water from the spray head 24 and fall into the seedling tray 11 to irrigate the rice seedlings. In this way, the motor 2 is controlled to drive the disc 4 to rotate, so that multiple seedling trays 11 can be located below the spray head 24 to complete the irrigation work.

[0042] After the rice seedlings in the seedling tray 11 are irrigated by the sprinkler head 24, they will penetrate into the soil for root absorption. Excess water will flow from the flow hole 12 into the limit groove 9, and then enter the channel 1 from the limit groove 9 and flow into the water guide groove 13.

[0043] When the motor 2 drives the disc 4 to rotate, so that one of the placement discs 8 moves to one side of the interface 20, as the disc 4 continues to drive the placement disc 8 close to the interface 20, the ball 19 first contacts the bottom of the slope of the outer wall of the interface 20, and as the disc 4 drives the placement disc 8 to move continuously, the ball 19 gradually moves to the peak of the slope of the outer wall of the interface 20, which will compress the spring groove 16 and drive the baffle 17 to move into the spring groove 15, thereby making the sealing gasket on one side of the baffle 17 unable to contact the two ends of the water guide groove 13, so that the water inside the water guide groove 13 can flow into the interface 20. At this time, the motor 2 will stop rotating because the placement disc 8 opposite to the placement disc 8 is using the spray head 24 to irrigate the seedling tray 11. That is, the two relative placement plates 8 do not affect each other in drainage and irrigation. When the irrigation work is completed, the motor 2 drives the disc 4 to rotate, so that the ball 19 slides to the other slope bottom of the outer wall of the interface 20, and under the rebound potential energy of the spring groove 16, the baffle 17 is driven to move from the spring groove 15, and the sealing gasket is used again to block the two ends of the water guide groove 13, so that the water guide groove 13 cannot drain, and the irrigation and drainage work is performed reciprocally. When the water in the water guide groove 13 flows into the interface 20, the interface 20 will flow into the water flow groove 21 to be collected and enter the filter box 22 for processing, and then enter the water pump 23 and re-irrigate the seedling tray 11 with new water, so as to perform water recycling work in a reciprocating cycle.

[0044] Example 2

[0045] Combination Figure 1-4 Based on Example 1, this embodiment is further improved in that the elastic unit includes a fixed plate 14, a spring groove 15, a spring 16, a baffle 17, a lifting plate 18 and a contact unit, the fixed plate 14 is fixed to the two ends of the placement disk 8 extending from the channel three, and the spring groove 15 is opened on the fixed plate 14, one end of the spring 16 is fixed in the spring groove 15, and the other end of the spring 16 is connected to the baffle 17, and the lifting plate 18 is fixed to the end of the baffle 17 away from the placement disk 8.

[0046] The contact unit includes a ball 19 , and a plurality of ball 19 are rolled and embedded on the lifting plate 18 , and a sealing gasket is provided at one end of the baffle plate 17 close to the placement plate 8 to contact the water guide groove 13 .

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
