Description

Technical Field

[0001] This utility model relates to the field of grain planting technology, specifically to a grain planting seedling rack. Background Technology

[0002] With the development of modern agricultural technology, the efficiency and yield of grain cultivation have been significantly improved. Seedling raising, as a crucial step in grain cultivation, is of great importance to ensuring healthy seedling growth and increasing final yield. Traditional seedling raising methods typically rely on manual experience for irrigation management, which not only consumes a large amount of manpower and resources but also makes it difficult to precisely control water supply, easily leading to water waste or insufficient irrigation affecting seedling growth.

[0003] While some automated irrigation systems exist in the current technology, most of these systems can only achieve timed and quantitative irrigation, and cannot dynamically adjust the irrigation amount according to the actual water level in each seedling trough. Especially in the process of grain seedling cultivation, different types of grains have different water requirements, and even the same variety may have varying water needs at different growth stages. Therefore, how to flexibly adjust and accurately control the water level in the seedling trough during irrigation to meet the needs of different crops and their growth stages, and automatically stop irrigation when a designated height is reached, has become an urgent technical problem to be solved.

[0004] Therefore, a grain cultivation seedling rack is needed to solve the above problems. Utility Model Content

[0005] To address the aforementioned problem—namely, the difficulty of precisely controlling water supply in existing irrigation equipment—this invention provides a grain seedling cultivation rack.

[0006] A grain seedling raising rack includes a seedling base and a water tank. The seedling base has a seedling trough and a water passage hole inside, which is in fluid communication with the water tank. The side of the seedling trough, near the top, is connected to the water passage hole via a water supply hole. A baffle plate is slidably mounted on the side of the water supply hole. A sliding plate is vertically slidably mounted on the side of the seedling trough. A top-blocking sliding plate is slidably mounted through the sliding plate and is drivenly connected to the baffle plate. By slidably mounting the baffle plate on the side of the water supply hole and the top-blocking sliding plate through the sliding plate, and drivingly connecting the baffle plate to the top-blocking sliding plate, when the water level in the seedling trough reaches the height of the top-blocking sliding plate, the water in the seedling trough pushes the top-blocking sliding plate, causing the top-blocking sliding plate to drive the baffle plate to slide, blocking the water supply hole and preventing water from continuing to flow into the seedling trough. This design allows the device to automatically and accurately control the water level in the seedling trough.

[0007] The above-mentioned grain planting seedling rack includes a first seedling base, a second seedling base, and a third seedling base. The first seedling base is fixedly installed on the base plate by a frame plate. The second seedling base is fixedly installed on the top of the first seedling base by a first support rod. The third seedling base is fixedly installed on the top of the second seedling base by a second support rod. The top of the first seedling base, the second seedling base, and the third seedling base are all provided with multiple seedling troughs. The water passage holes are all provided through the interior of the first seedling base, the second seedling base, and the third seedling base near the bottom.

[0008] In the aforementioned grain seedling cultivation rack, the water tank is fixedly installed on the upper surface of the base plate. A water pump is fixedly installed at one end of the water tank and electrically connected to an external power source. The water inlet of the water pump is in fluid communication with the interior of the water tank near the bottom. The water outlet of the water pump is connected to one end of the water passage hole on the first seedling base via a water supply pipe. The other end of the water passage hole on the first seedling base is connected to one end of the water passage hole on the second seedling base via a first water passage pipe. The other end of the water passage hole on the second seedling base is connected to one end of the water passage hole on the third seedling base via a second water passage pipe. The other end of the water passage hole on the third seedling base is connected to the interior of the water tank near the top via an outlet pipe. A pressure valve is installed inside the outlet pipe. By installing the pressure valve, the water in the water passage hole has sufficient pressure to enter the seedling trough.

[0009] In the aforementioned grain seedling rack, an inner cavity is provided on the side of the water supply hole away from the seedling trough. The baffle plate slides in the inner cavity via a tension spring. A top groove matching the baffle plate is provided on the side of the water supply hole near the seedling trough. An extension groove is provided at the bottom of the inner cavity. An extension slider is fixedly installed at the bottom of the baffle plate and slides in the extension groove. When one end of the baffle plate abuts against the top groove, it can block the flow of water in the water supply hole.

[0010] In the aforementioned grain seedling raising rack, an adjustment cavity is provided on the side of the seedling trough away from the water supply hole, and a sliding plate cavity is provided on the outer side of the seedling trough. The sliding plate cavity extends through the adjustment cavity, and the sliding plate slides within the sliding plate cavity. A sliding sleeve is fixedly installed through the sliding plate, and a push-up sliding plate slides within the sliding sleeve. Spring cavities are provided on both sides of the interior of the sliding plate, and an inner sliding plate is slidably installed inside the spring cavities via push-up springs. A pressing rod is fixedly installed at the top of the outer side of the inner sliding plate, and a friction block is fixedly installed near the bottom of the outer side of the inner sliding plate. The outer ends of the pressing rod and the friction block extend outside the sliding plate. The pressing rod is located outside the sliding plate cavity, and the friction block abuts against the side of the sliding plate cavity. By setting the push-up sliding plate on a sliding plate that can slide up and down, the height of the push-up sliding plate can be adjusted by sliding the sliding plate up and down, thereby facilitating the adjustment of the water level in the seedling trough. The friction block abuts against the side of the sliding plate cavity to prevent the sliding plate from sliding up and down on its own, and pressing down the pressing rod facilitates the sliding of the sliding plate.

[0011] In the aforementioned grain seedling rack, a sliding cavity is connected to the outer side of the adjusting cavity. A sliding seat is slidably installed inside the sliding cavity, and a ball bearing is provided on the outer side of the sliding seat. The outer end of the abutting slide plate abuts against the inner side of the sliding seat. A first rope hole is connected to the inner side of the sliding cavity near the bottom. A pulley cavity is connected to the other end of the first rope hole, and a second rope hole is connected to the other end of the pulley cavity. The other end of the second rope hole is connected to the end of the extending slide groove near the seedling trough. A pulley sleeve is slidably installed inside the pulley cavity, and the pulley sleeve is connected to a second pull... The rope is connected to the extension slider. The second pull rope passes through the second rope hole. A pulley is rotatably mounted on the pulley sleeve. A first pull rope is slidably mounted inside the first rope hole. One end of the first pull rope is connected to the slide block. The other end of the first pull rope passes around the pulley and is connected to the end of the pulley cavity near the first rope hole. By reasonably setting the pulley, a labor-saving effect can be achieved, so that the sliding slide block only needs a small force to drive the blocking plate to slide. This can prevent the situation where the water's thrust on the sliding slide block is too small to drive the blocking plate to slide.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a baffle plate slidably installed on the side of the water supply hole, and a sliding plate for supporting the top plate slidably installed on the sliding plate. The baffle plate is driven to connect with the top plate. When the water level in the seedling trough reaches the height of the top plate, the water in the seedling trough pushes the top plate, which in turn drives the baffle plate to slide, blocking the water supply hole and preventing water from the water outlet from continuing to flow into the seedling trough. This design enables the device to automatically and accurately control the water level in the seedling trough.

[0014] 2. This utility model sets the abutting slide plate on a slide plate that can slide up and down. The height of the abutting slide plate can be adjusted by sliding the slide plate up and down, thereby facilitating the adjustment of the water level in the seedling trough. The friction block abuts the side of the slide plate cavity to prevent the slide plate from sliding up and down on its own. Pressing down the pressing rod facilitates the sliding of the slide plate.

[0015] 3. By reasonably setting the pulleys, this utility model can achieve a labor-saving effect, so that only a small force is needed to push the sliding plate against the slide to make the sliding slide move the blocking plate. This can prevent the situation where the water's thrust on the sliding plate is too small to drive the blocking plate to slide. Attached Figure Description

A seedling trough 2 is provided on the seedling base, and a water passage 3 is provided inside the seedling base, which is in fluid communication with the water tank 1. The side of the seedling trough 2, near the top, is connected to the water passage 3 via a water supply hole 4. A baffle plate 5 is slidably installed on the side of the water supply hole 4. A sliding plate 6 is vertically slidably installed on the side of the seedling trough 2, and a top-mounted sliding plate 7 is slidably installed through the sliding plate 6. The top-mounted sliding plate 7 drives the baffle plate 5. Connection; By sliding a baffle plate 5 on the side of the water supply hole 4 and sliding a top sliding plate 7 through the slide plate 6, and driving the baffle plate 5 and the top sliding plate 7 to connect, when the water level in the seedling trough 2 reaches the height of the top sliding plate 7, the water in the seedling trough 2 will push the top sliding plate 7, thereby causing the top sliding plate 7 to drive the baffle plate 5 to slide, blocking the water supply hole 4 and preventing the water in the water passage hole 3 from continuing to flow into the seedling trough 2. This setting enables the device to automatically and accurately control the water level in the seedling trough 2.

[0025] like Figure 1As shown, the seedling tray includes a first seedling tray 8, a second seedling tray 9, and a third seedling tray 10. The first seedling tray 8 is fixedly installed on the base plate 12 by a frame plate 11.

Water passage holes 3 are opened through the interior of the first seedling tray 8, the second seedling tray 9, and the third seedling tray 10 near the bottom.

[0026] like Figure 1 As shown, the water tank 1 is fixedly installed on the upper surface of the base plate 12. A water pump 15 is fixedly installed at one end of the water tank 1. The water pump 15 is electrically connected to an external power source. The inlet of the water pump 15 is in fluid communication with the interior of the water tank 1 near the bottom. The outlet of the water pump 15 is connected to one end of the water passage hole 3 on the first seedling bed 8 through the water supply pipe 16.

[0028] like Figure 3 and Figure 5As shown, an adjustment cavity 25 is provided on the side of the seedling trough 2 away from the water supply hole 4. A sliding plate cavity 26 is provided on the outer side of the seedling trough 2, and the sliding plate cavity 26 is provided through the adjustment cavity 25.

Spring cavities 28 are provided on both sides of the inside of the sliding plate 6. An inner sliding plate 30 is slidably installed inside the spring cavity 28 through the abutting spring 29. A pressing rod 31 is fixedly installed on the top of the outer side of the inner sliding plate 30. A pressing rod 31 is fixedly installed on the bottom of the outer side of the inner sliding plate 30. A friction block 32 is fixedly installed. The outer ends of the pressing rod 31 and the friction block 32 both extend to the outside of the slide plate 6. The pressing rod 31 is located outside the slide plate cavity 26, and the friction block 32 abuts against the side of the slide plate cavity 26. By setting the abutting slide plate 7 on the slide plate 6 that can slide up and down, the height of the abutting slide plate 7 can be adjusted by sliding the slide plate 6 up and down, thereby facilitating the adjustment of the water level in the seedling trough 2. By abutting the side of the slide plate cavity 26 with the friction block 32, the slide plate 6 can be prevented from sliding up and down on its own.

A first rope hole 36 is connected to the inner side of the sliding cavity 33 near the bottom. The other end of the first rope hole 36 is connected to a pulley cavity 37. The other end of the pulley cavity 37 is connected to a second rope hole 38. The other end of the second rope hole 38 is connected to the end of the extension slide 23 near the seedling trough 2. A pulley sleeve 39 is slidably installed inside the pulley cavity 37. The pulley sleeve 39 is connected to the extension slide 23 via a second pull rope 40. The slider 24 is connected, the second pull rope 40 is set through the second rope hole 38, the pulley 41 is rotatably installed on the pulley sleeve 39, and the first pull rope 42 is slidably installed inside the first rope hole 36. One end of the first pull rope 42 is connected to the slide block 34, and the other end of the first pull rope 42 passes around the pulley 41 and is connected to the end of the pulley cavity 37 near the first rope hole 36. By reasonably setting the pulley 41, a labor-saving effect can be achieved, so that the sliding slide block 34 only needs to be given a small force to make the sliding slide block 34 drive the blocking plate 5 to slide. This can prevent the situation where the water's thrust on the sliding slide block 7 is too small to drive the blocking plate 5 to slide.
