Description

Technical Field

[0001] This utility model relates to the field of crop cultivation technology, specifically to a cultivation device for measuring crop water consumption. Background Technology

[0002] Currently, when using pot experiments to study the water and fertilizer utilization characteristics of drought-resistant crops such as wheat with a large planting area and hybrid millet with great potential for promotion, it is often necessary to collect accurate water consumption data.

[0003] For example, a cultivation device for accurately measuring crop water consumption, authorized by publication number CN203167654U, includes a planting cultivation cylinder and a planting cover. A communicating vessel is provided at the bottom of the planting cultivation cylinder. Several planting holes are provided on the planting cover, and a planting block is placed on each planting hole. The planting block includes a disc adapted to the size of the planting hole and a hollow column vertically positioned in the center of the disc. However, this document still has shortcomings. In use, crop planting is very simple because both the disc and the hollow column of the planting block are divided into two equal parts along their axial direction. During use, only the plant seedling needs to be placed between the two parts of the planting block. Then, assemble the planting block along with the plant seedling onto the planting cover. Because the planting block disc has a groove that matches the size of the planting hole, the planting block is securely attached to the planting cover and will not tilt or fall over as the crop grows. However, as the crop grows and consumes water, the water supply will gradually decrease, making it difficult to keep the crop roots constantly submerged. At the same time, as the crop grows, its water requirements will change. Traditional methods require re-clamping the crop to adjust the depth of the crop roots inserted into the water, which is cumbersome and inconvenient for adjusting the depth of the crop roots inserted into the water. Utility Model Content

[0004] The purpose of this invention is to solve the problem of not being able to keep the roots of crops in water at all times, and to propose a cultivation mechanism for measuring the water consumption of crops.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a cultivation mechanism for measuring crop water consumption, including a water trough and a support plate. The support plate is fitted with a clearance inside the water trough. A moving mechanism is provided below the support plate. A third support is provided above the support plate. A second sleeve is fixedly connected inside the third support. A second support rod is slidably connected inside the second sleeve. A spring is provided inside the second sleeve. The two ends of the spring are fixedly connected to the second sleeve and the second support rod, respectively. An adjustment mechanism is provided above the support plate. The adjustment mechanism includes a first support and a second support. The first support and the second support are both fixedly connected to the upper surface of the support plate. The first support and the support plate are rotatably connected to the outer walls of both ends of a screw through bearings. A rotating wheel is fixedly connected to the upper end of the screw. A threaded block is threadedly connected to the outer wall of the screw. The outer wall of the threaded block is fixedly connected to the third support. The second support and the support plate are fixedly connected to the two ends of a sliding rod. A slider is slidably connected to the outer wall of the sliding rod. The outer wall of the slider is fixedly connected to the third support.

[0007] Preferably, the moving mechanism includes a foam board and first support rods. The foam board is fixedly connected to the lower surface of the support plate, the upper ends of the two first support rods are fixedly connected to the support plate, the outer walls of the first support rods are slidably connected to the first sleeves, and the ends of the two first sleeves are fixedly connected to the water tank.

[0008] Preferably, an arc-shaped plate is fixed to the end of the second support rod, and a handle is fixed to the upper surface of the arc-shaped plate.

[0009] Preferably, the inner wall of the arc-shaped plate is fixedly connected to the clamping plate by a connecting column.

[0010] Preferably, two moving blocks are fixed to the outer wall of the arc-shaped plate, and the outer wall of the moving blocks is slidably connected to the sliding groove provided in the third support.

[0011] Preferably, the water tank is fixedly connected to the outer wall of the end of the drain pipe, and a valve is installed on the outer wall of the drain pipe.

[0012] Preferably, the water tank is fixedly connected to the outer wall of the end of the transparent tube.

[0013] The cultivation mechanism for measuring crop water consumption proposed in this utility model has the following advantages: Through the cooperation between the foam board, the first support rod, and the first sleeve, the foam board floats on the water surface. As the crop absorbs and consumes water, the amount of water in the tank decreases, and the foam board always floats on the liquid surface. The vertical height of the foam board changes with the change of the liquid level, which in turn changes the height of the support plate. The first support rod and the first sleeve guide the movement of the support plate, making the movement of the support plate more stable. When the support plate moves, it drives the crop to move, so that the crop roots are always in the water. This makes it easy to keep the crop roots in the water during measurement.

[0014] Through the cooperation of the first support, screw, rotating wheel, threaded block, second support, slide bar, and slider, the rotating wheel drives the screw to rotate, the screw drives the threaded block to move, the threaded block drives the third support to move, and the slide bar and slider guide the movement of the third support. When the third support moves, it drives the crop to move, and the depth of the crop's roots inserted into the water changes. After adjusting the depth of the crop's roots into the water to the required depth, the rotating wheel stops rotating. There is no need to re-clamp the crop to adjust the depth of the crop's roots into the water. The operation is relatively simple and convenient for adjusting the depth of the crop's roots into the water. Attached Figure Description

A third support 5 is provided above the support plate 2. A second sleeve 6 is fixedly connected inside the third support 5. There are four second sleeves 6 in total. A second support rod 7 is slidably connected inside the second sleeve 6. The second support rod 7 slides inside the second sleeve 6. A spring 8 is provided inside the second sleeve 6. The model of the spring 8 is selected according to the actual use requirements to meet the working needs. The two ends of the spring 8 are fixedly connected to the second sleeve 6 and the second support rod 7 respectively. The spring 8 can drive the second support rod 7 to move under the elastic action. An adjustment mechanism 4 is provided above the support plate 2 to adjust the depth of crop roots inserted into the water.

[0023] An arc-shaped plate 9 is fixedly connected to the end of the second support rod 7. The second support rod 7 moves together with the arc-shaped plate 9. A handle 10 is fixedly connected to the upper surface of the arc-shaped plate 9. The handle 10 drives the arc-shaped plate 9 to move. The inner wall of the arc-shaped plate 9 is fixedly connected to the clamping plate 11 through a connecting column. The arc-shaped plate 9 drives the clamping plate 11 to move. Two moving blocks 12 are fixedly connected to the outer wall of the arc-shaped plate 9. The arc-shaped plate 9 and the two moving blocks 12 move together. The outer wall of the moving blocks 12 is slidably connected to the sliding groove provided in the third bracket 5. The moving blocks 12 slide in the corresponding sliding groove in the third bracket 5. The moving blocks 12 and the third bracket 5... The internal groove guides the movement of the arc plate 9. The water tank 1 is fixedly connected to the outer wall of the end of the drain pipe 13. The drain pipe 13 facilitates the drainage of water from the inside of the water tank 1. A valve 14 is installed on the outer wall of the drain pipe 13. The valve 14 controls the opening and closing of the drain pipe 13. The water tank 1 is fixedly connected to the outer wall of the end of the transparent pipe 15. The transparent pipe 15 is connected to the inside of the water tank 1, and the surface of the transparent pipe 15 is provided with scale lines. The water level in the water tank 1 can be easily known through the transparent pipe 15. The scale line values ​​on the transparent pipe 15 correspond to the volume values ​​of the water in the water tank 1.

[0024] The moving mechanism 3 includes a foam board 301, a first support rod 302, and a first sleeve 303. The foam board 301 is fixed to the lower surface of the support plate 2. The foam board 301 can float on the water surface and its vertical height can change according to the change of the liquid level. The upper ends of the two first support rods 302 are fixedly connected to the support plate 2. The two first support rods 302 move together with the support plate 2. The outer wall of the first support rod 302 is slidably connected to the first sleeve 303. The first support rod 302 slides inside the first sleeve 303. The ends of the two first sleeves 303 are fixedly connected to the water tank 1. The first support rod 302 and the first sleeve 303 play a guiding role in the movement of the support plate 2, making the movement of the support plate 2 more stable.

[0025] As the crop absorbs and consumes water, the amount of water in the tank 1 decreases, and the foam board 301 remains floating on the surface. The vertical height of the foam board 301 changes with the change in the water level, which in turn changes the height of the support plate 2. The first support rod 302 and the first sleeve 303 guide the movement of the support plate 2, making the movement of the support plate 2 more stable. When the support plate 2 moves, it drives the crop to move, keeping the crop's roots in the water at all times. This makes it easier to keep the crop's roots in the water during measurement.

[0026] The adjusting mechanism 4 includes a first bracket 401, a screw 402, a rotating wheel 403, a threaded block 404, a second bracket 405, a sliding rod 406, and a slider 407. The first bracket 401 and the second bracket 405 are both fixed to the upper surface of the support plate 2. The first bracket 401 and the support plate 2 are rotatably connected to the outer walls of both ends of the screw 402 via bearings. The rotating wheel 403 is fixed to the upper end of the screw 402, driving the screw 402 to rotate. A threaded block 404 is threadedly connected to the outer wall of the screw 402. 04. The screw 402 drives the threaded block 404 to move. The outer wall of the threaded block 404 is fixedly connected to the third bracket 5. The threaded block 404 drives the third bracket 5 to move. The second bracket 405 and the support plate 2 are fixedly connected to the two ends of the slide rod 406 respectively. The outer wall of the slide rod 406 is slidably connected to the slider 407. The slider 407 slides on the outer wall of the slide rod 406. The outer wall of the slider 407 is fixedly connected to the third bracket 5. The slider 407 and the slide rod 406 guide the movement of the third bracket 5.

[0027] The rotating wheel 403 drives the screw 402 to rotate, the screw 402 drives the threaded block 404 to move, and the threaded block 404 drives the third support 5 to move. The slide bar 406 and the slider 407 guide the movement of the third support 5. When the third support 5 moves, it drives the crop to move, and the depth of the crop's roots inserted into the water changes. After adjusting the depth of the crop's roots into the water to the required depth, the rotating wheel 403 stops rotating. There is no need to re-clamp the crop to adjust the depth of the crop's roots into the water. The operation is relatively simple and convenient for adjusting the depth of the crop's roots into the water.

[0028] Working principle:

[0029] When using a cultivation facility that measures crop water consumption to measure the water consumption of cultivated crops;

[0030] Crop positioning stage:

[0031] Pulling the two handles 10 on one side of the third support 5 causes the arc plate 9 of the handle 10 to move. The movement of the moving block 12 and the sliding groove set in the third support 5 makes the movement of the arc plate 9 more stable. The arc plate 9 drives the second support rod 7 to move. The second support rod 7 slides inside the second sleeve 6 and compresses the spring 8. When the arc plate 9 moves, it drives the clamping plate 11 to move. The crop is placed between the two clamping plates 11. When the handle 10 is released, the spring 8 drives the second support rod 7 to slide in the opposite direction under the elastic action. The clamping plate 11 moves in the opposite direction and contacts the outer wall of the crop to clamp the crop. There are four clamping plates 11 in total. When in use, they can clamp and fix two crops to make the two crops the same height.

[0032] Crop root height regulation stages:

[0033] Water for crop growth is added to the inside of the water tank 1 (it can be added from the top of the water tank 1; the third support 5 has multiple hollowed-out parts, and the support plate 2 also has hollowed-out holes). Rotate the wheel 403, which drives the screw 402 to rotate. The screw 402 drives the threaded block 404 to move, and the threaded block 404 drives the third support 5 to move. The slide bar 406 and the slider 407 guide the movement of the third support 5. When the third support 5 moves, it drives the crop to move, and the depth of the crop roots inserted into the water changes, so that the crop roots are at the required depth in the water and the wheel 403 is stopped to rotate.

[0034] Crop water consumption measurement stage:

[0035] The crop roots are inserted into the water. A water tank 1 is connected to a transparent tube 15. The liquid level in the water tank 1 is the same as the liquid level in the transparent tube 15. A foam board 301 floats on the water surface. As the crop absorbs and consumes water, the water volume in the water tank 1 decreases, and the foam board 301 remains floating. The vertical height of the foam board 301 changes with the liquid level, which in turn changes the height of the support plate 2. The first support rod 302 and the first sleeve 303 guide the movement of the support plate 2, making its movement more stable. The support plate 2 moves the crop, ensuring that the crop roots remain submerged. This method facilitates measurements by keeping the crop roots submerged. As the crop grows, when it is necessary to adjust the depth of the crop roots inserted into the water, the rotating wheel 403 is turned, the height of the third support 5 changes, and thus the depth of the crop roots inserted into the water changes. After adjusting the depth of the crop roots inserted into the water to the required depth, the rotating wheel 403 is stopped. There is no need to re-clamp the crop to adjust the depth of the crop roots inserted into the water. The operation is relatively simple and convenient for adjusting the depth of the crop roots inserted into the water. The liquid level in the water tank 1 and the transparent tube 15 are the same. The water consumption of the crop is determined by observing the difference between the number of days the crop grows and the change in the liquid level in the transparent tube 15. The water consumption is the water consumption of the two crops.
