Description

Technical Field

[0001] This application relates to the field of seedling raising machine technology, and in particular to a water spraying device for a seedling raising machine. Background Technology

[0002] In modern agricultural planting, seedling raising machines, as key equipment for achieving mechanized and large-scale seedling raising of crops such as rice, greatly improve production efficiency and seedling quality. In the traditional seedling raising process, sowing is a core step, and evenly and appropriately moistening the seedbed soil (the soil in the seedling tray) before and after sowing is a fundamental step to ensure successful seed germination and subsequent healthy seedling growth. Moist soil not only provides the necessary moisture for seed germination but also improves the cohesion between soil particles, facilitating seed fixation and close contact with the soil after sowing, preventing seeds from becoming airborne, and thus ensuring uniform and consistent seedling emergence.

[0003] However, most existing seedling raising machines lack a device to spray water and moisten the soil between the soil spreading and sowing stages. Dry soil cannot hold the seeds in place, and the seeds are likely to be blown away by the wind or sink unevenly due to gravity, affecting the uniformity of germination. Furthermore, the adhesion between the seeds and the unwatered soil is weak, and subsequent watering after sowing can easily disrupt the seed position, leading to uneven seed distribution and reduced germination rate. Therefore, it is necessary to develop a water spraying device that can work in conjunction with the main body of the seedling raising machine to automatically and evenly and precisely moisten the soil in the seedling tray before sowing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a water spraying device for a seedling raising machine. The technical problem it solves is that existing seedling raising machines lack a soil moistening device between the soil spreading and sowing processes, affecting the uniformity of seedling emergence and the emergence rate. To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: A water spraying device for a seedling raising machine, comprising: Seedling machine frame; The mounting frame is fixedly installed on the upper end face of the seedling machine frame, and a water pump is fixedly installed on the upper end face of the mounting frame. A water spraying assembly, comprising a water supply pipe and a water spraying pipe, both of which are fixedly connected to a mounting bracket. One end of the water supply pipe is connected to a water pump, and the other end is connected to the water spraying pipe. The water spraying pipe has several uniformly spaced water spray holes along its axial direction. The water receiving tank is located directly below the water spray pipe and is fixedly connected to the seedling raising machine frame. The water receiving tank is open.

[0005] Furthermore, end caps are fixedly installed at both ends of the water spray pipe, with one end of the end cap being open.

[0006] Furthermore, the inner wall of the water spray pipe is provided with an arc-shaped baffle, and a swing rod is fixedly provided on both ends of the arc-shaped baffle, with a drive shaft rotatably connected to the upper end of the swing rod.

[0007] Furthermore, the drive shaft is connected to a first bevel gear and a second bevel gear via a key. The second bevel gear and the first bevel gear are positioned with a clearance between them. The second bevel gear is meshed with a half bevel gear. The half bevel gear is fixedly connected to a main shaft. The other end of the main shaft is connected to a motor, which is fixedly installed inside the end cover.

[0008] Furthermore, a connecting plate is fixedly disposed inside the end cap, and the connecting plate has a through hole for the drive shaft to pass through, and a sealing gasket is fixedly disposed on the inner wall of the through hole.

[0009] Furthermore, a pressure plate is fixedly provided on the upper surface of the arc-shaped baffle, and one end face of the pressure plate is fixedly connected to the swing rod.

[0010] Furthermore, a support block is provided below the water spray pipe, and the support block is fixedly connected to the mounting bracket.

[0011] Furthermore, a drain outlet is provided at the bottom of the water receiving tank, and the drain outlet is connected to an external drain pipe.

[0012] The beneficial effects of this utility model are: the water spraying device is set between the soil spreading device and the sowing device of the seedling machine, which wets the soil in the seedling tray before sowing, avoids uneven sinking of seeds due to external force, ensures uniform emergence, enhances the adhesion between seeds and soil, prevents subsequent watering from washing away the seeds, and improves the emergence rate.

[0013] By setting up an arc-shaped baffle, a swing arm, and a bevel gear transmission mechanism, the bevel gear transmission mechanism drives the swing arm to rotate, which in turn drives the arc-shaped baffle to reciprocate along the inner wall of the water spray pipe. This reciprocating motion mechanism can realize the dynamic opening and closing of the water spray holes, achieve intermittent water spraying, avoid spraying water onto the connection point of the seedling tray groove, ensure the uniformity of soil moisture, and save water resources.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows: like Figures 1-2 As shown, a water spraying device for a seedling raising machine includes a seedling raising machine frame 1. A mounting frame 2 is fixedly installed on the upper surface of the seedling raising machine frame 1. A water pump 3 is fixedly installed on the upper surface of the mounting frame 2. The water pump 3 is connected to a water spraying assembly 4. The water spraying assembly 4 includes a water delivery pipe 41 and a water spraying pipe 42. Both the water spraying pipe 41 and the water delivery pipe 42 are fixedly connected to the mounting frame 2. One end of the water delivery pipe 41 is connected to the water pump 3, and the other end of the water delivery pipe 41 is connected to the water spraying pipe 42. The water spraying pipe 42... A plurality of uniformly spaced water spray holes 43 are provided along the axial direction. A water receiving tank 5 is provided directly below the water spray pipe 42. The water receiving tank 5 is fixedly connected to the seedling machine frame 1 and is open. The water spray device is located between the soil spreading device and the sowing device of the seedling machine. Before sowing, the soil 24 in the seedling tray 21 is moistened to prevent the seeds from sinking unevenly due to external force, ensure the uniformity of seedling emergence, enhance the adhesion between the seeds and the soil 24, prevent the seeds from being washed away by subsequent watering, and improve the seedling emergence rate.

[0024] like Figure 3 As shown, end caps 6 are fixedly installed at both ends of the water spray pipe 42, and one end of the end cap 6 is open.

[0025] like Figures 4-7 As shown, the inner wall of the water spray pipe 42 is provided with an arc-shaped baffle 7. A swing rod 8 is fixedly installed on both ends of the arc-shaped baffle 7. A drive shaft 9 is rotatably connected to the upper end of the swing rod 8. The drive shaft 9 is keyed to a first bevel gear 10 and a second bevel gear 11. The second bevel gear 11 and the first bevel gear 10 are positioned with a gap between them. The second bevel gear 11 is meshed with a half-bevel gear 12. The half-bevel gear 12 is fixedly connected to a main shaft 13. The other end of the main shaft 13 is connected to a motor 14, which is fixedly installed inside the end cover 6. By setting up the arc-shaped baffle 7, the swing rod 8, and the bevel gear transmission mechanism, the bevel gear transmission mechanism drives the rotation of the swing rod 8, thereby driving the arc-shaped baffle 7 to reciprocate along the inner wall of the water spray pipe 42 in a curved motion. This curved reciprocating motion mechanism can dynamically open and close the water spray holes 43, achieving intermittent water spraying, avoiding spraying water onto the connection point of the groove 22 in the seedling tray 21, ensuring the uniformity of soil moisture 24, and saving water resources.

[0026] In use, the motor 14 is started, and the motor 14 transmits power to the half-bevel gear 12 through the main shaft 13. The half-bevel gear 12 begins to rotate. When the teeth of the half-bevel gear 12 rotate to mesh with the first bevel gear 10, the half-bevel gear 12 will drive the first bevel gear 10 to rotate counterclockwise. The counterclockwise rotation of the first bevel gear 10 will drive the drive shaft 9 to rotate counterclockwise. The rotation of the drive shaft 9 will drive the swing arm 8 to swing counterclockwise along the end face of the water spray pipe 42, thereby driving the arc-shaped baffle 7 to rotate counterclockwise along the inner wall of the water spray pipe 42. The arc-shaped baffle 7 rotates away from the water spray hole 43, and the water spray hole 43 is now in the open state. Water will be sprayed into the seedling tray 21 below through the spray hole 43; when the teeth of the half bevel gear 12 rotate to mesh with the second bevel gear 11, the half bevel gear 12 will drive the second bevel gear 11 to rotate clockwise, the clockwise rotation of the second bevel gear 11 will drive the drive shaft 9 to rotate clockwise, the rotation of the drive shaft 9 will drive the swing arm 8 to swing clockwise along the end face of the spray pipe 42, and then drive the arc baffle 7 to rotate clockwise along the inner wall of the spray pipe 42. The arc baffle 7 rotates to the spray hole 43 and blocks the spray hole 43. At this time, the spray hole 43 is in a closed state, and the water in the spray pipe 42 stops spraying water into the seedling tray 21 below.

[0027] Furthermore, the speed of motor 14 is adjustable, and the speed of motor 14 is set in coordination with the distance the seedling tray 21 moves to ensure that when the arc-shaped baffle 7 opens the water spray hole 43, the soil 24 part in the seedling tray 21 is just below the water spray pipe 42, and when the arc-shaped baffle 7 closes the water spray hole 43, the part of the groove 22 connecting part in the seedling tray 21 is just below the water spray pipe 42; the motor 14 is driven by the external seedling machine control system, and the speed of motor 14 is synchronized with the speed of the external seedling tray conveyor belt.

[0028] like Figure 4As shown, a connecting plate 15 is fixedly installed inside the end cover 6. The connecting plate 15 divides the end cover 6 into a closed area and an open area. The motor 14, the half bevel gear 12, the first bevel gear 10, and the second bevel gear 11 are all located in the closed area. The connecting plate 15 has a through hole 16 for the drive shaft 9 to pass through. A sealing gasket 17 is fixedly installed on the inner wall of the through hole 16. The purpose of this structure is to ensure sealing and prevent water from the spray pipe 42 from entering the closed area of ​​the end cover 6.

[0029] Furthermore, a pressure plate 18 is fixedly installed on the upper end face of the arc-shaped baffle 7, and one end face of the pressure plate 18 is fixedly connected to the swing rod 8. The main purpose of this structure is to apply pressure to the arc-shaped baffle 7, so that the arc-shaped baffle 7 fits more tightly with the inner wall of the water spray pipe 42, and the water blocking effect is better.

[0030] It needs to be explained that, for example Figure 2 As shown, a support block 19 is provided below the water spray pipe 42, and the support block 19 is fixedly connected to the mounting frame 2; the purpose of this structure is to further ensure the stability of the water spray pipe 42.

[0031] Furthermore, such as Figure 1 As shown, the bottom of the water receiving tank 5 is provided with a drain outlet 20, which is connected to an external drain pipe.

[0032] The working principle and process of this utility model are as follows: When the seedling tray 21 moves below the water spray pipe 42, the water pump 3 is started. The water pump 3 delivers water to the water spray pipe 42 through the water supply pipe 41. The motor 14 starts and transmits power to the semi-bevel gear 12 through the main shaft 13. The semi-bevel gear 12 begins to rotate. When the teeth of the semi-bevel gear 12 rotate to mesh with the first bevel gear 10, the semi-bevel gear 12 drives the first bevel gear 10 to rotate counterclockwise. The counterclockwise rotation of the first bevel gear 10 drives the drive shaft 9 to rotate counterclockwise. The rotation of the drive shaft 9 drives the swing arm 8 to swing counterclockwise along the end face of the water spray pipe 42, thereby driving the arc-shaped baffle 7 to rotate counterclockwise along the inner wall of the water spray pipe 42. The arc-shaped baffle 7 rotates away from the water spray hole 43, and the water spray hole 43 is now open. The water in the water spray pipe 42 then flows through the water spray hole 43. 3. The water is sprayed into the seedling tray 21 below. At this time, the area below the water spray pipe 42 is the part of the groove 22 in the seedling tray 21 that holds the soil 24. When the teeth of the half bevel gear 12 rotate to mesh with the second bevel gear 11, the half bevel gear 12 will drive the second bevel gear 11 to rotate clockwise. The clockwise rotation of the second bevel gear 11 will drive the drive shaft 9 to rotate clockwise. The rotation of the drive shaft 9 will drive the swing arm 8 to swing clockwise along the end face of the water spray pipe 42, and then drive the arc-shaped baffle 7 to rotate clockwise along the inner wall of the water spray pipe 42. The arc-shaped baffle 7 rotates to the water spray hole 43 and blocks the water spray hole 43. The water spray hole 43 is now in a closed state. The water in the water spray pipe 42 stops spraying water into the seedling tray 21 below. At this time, the area below the water spray pipe 42 is the connection point of the groove 22 in the seedling tray 21.
