Description

Technical Field

[0001] This invention relates to the field of planting equipment technology, and more specifically to a plant cultivation experimental device for measuring greenhouse gas emissions from plants. Background Technology

[0002] Greenhouse gases refer to gases in the atmosphere that can absorb long-wave radiation reflected from the ground and re-emit radiation. One of the important sources of greenhouse gases is agriculture. During plant cultivation, factors such as soil moisture content, plant growth stage, and soil structure all affect greenhouse gas emissions. Existing plant cultivation equipment used to measure greenhouse gas emissions has the following shortcomings in its application:

[0003] First, the size of the planting box cannot be adjusted. During the growth process, plants need a lot of space for root growth, and the root size is different at different growth stages. The existing planting box cannot be adjusted in size, which can easily lead to insufficient space for plant roots to grow.

[0004] Second, it is inconvenient to add soil to the planting boxes. When adding soil to the existing planting boxes, it is necessary to manually pour soil into the boxes and loosen the soil manually, which is time-consuming and labor-intensive. Summary of the Invention

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide a plant cultivation experimental device for measuring greenhouse gas emissions from plants, including a base, a support fixedly mounted on the base, multiple casters fixedly mounted on the base, a top cover rotatably mounted on the support, a planting mechanism fixedly mounted on the support, a soil-filling mechanism fixedly mounted on the base and support, a spraying mechanism fixedly mounted on the base and top cover, an electronic control board fixedly mounted on the base, and a detection mechanism fixedly mounted on the planting mechanism and top cover; the planting mechanism includes a second motor fixedly mounted on the support, a first gear ring rotatably mounted on the support, multiple drive components slidably mounted on the support, a base plate fixedly mounted on the support, multiple housings slidably mounted on the base plate, a first slide groove fixedly mounted on the housing, a baffle slidably mounted on the first slide groove, and a limiting component fixedly mounted on the baffle; the baffle and the base plate are connected by an elastic fabric.

[0008] The second motor drives the first gear ring to rotate, which in turn causes the drive assembly to slide on the support, thus moving the boxes away from each other. During the movement of the boxes, the baffles that were originally slidably set in the first sliding groove are exposed. The baffles are used to cover the gaps created after the movement of the two adjacent boxes. At the same time, the movement of the boxes will also move the baffles together. The elastic cloth is used to cover the gaps between the baffles and the bottom plate after the boxes are moved, realizing the function of adjustable box size, so that the plants have enough growing space. When the size of the boxes is adjusted, the drive assembly will also drive the screw conveyor assembly to move upward a short distance. During the movement, the bottom plate and the box will vibrate slightly, realizing the function of loosening the soil. After the size of the boxes is adjusted, there is still space. The limiting component can prevent the plants from collapsing. At the same time, the first motor drives the screw conveyor assembly to work. The soil in the storage tank enters the screw conveyor assembly through the first channel and is sent to the box by the screw conveyor assembly, realizing the function of automatic soil replenishment. The screw conveyor assembly is equipped with a soil spreading device, which can spread the soil evenly in the box and prevent the soil from accumulating on one side of the box.

[0009] Specifically, the drive assembly includes a third slide groove fixedly mounted on the bracket, a first connecting rod slidably mounted on the third slide groove, a first gear rotatably mounted on the bracket and meshing with a first gear ring, a second connecting rod slidably mounted on the first connecting rod, a fourth slide groove fixedly mounted on the second connecting rod, a third connecting rod slidably mounted on the fourth slide groove, and a linkage device fixedly mounted on the first connecting rod; the second connecting rod and the first connecting rod are connected by a first spring; one end of the third connecting rod is fixedly connected to the housing.

[0010] Specifically, the limiting component includes a spring telescopic rod fixedly mounted on the baffle and an arc-shaped plate fixedly mounted on the telescopic rod.

[0012] Specifically, the soil spreading device includes a conical cover fixedly mounted on the conveying rod and rotatably mounted on the fifth chute, a first through hole fixedly mounted on the conical cover, a second sleeve fixedly mounted on the conical cover, a rack fixedly mounted on the second sleeve, a transmission wheel rotatably mounted on the fourth connecting rod and meshing with the rack, a second conveying rod fixedly mounted on the transmission wheel, and multiple second through holes fixedly mounted on the second sleeve.

[0013] Specifically, the linkage device includes a first rotating shaft bracket fixedly mounted on the first connecting rod, a second rotating shaft bracket fixedly mounted on the first sleeve, and a fourth connecting rod rotatably mounted on the first rotating shaft bracket and the second rotating shaft bracket.

[0014] Specifically, the spraying mechanism includes a spray head fixed on the top cover, a water tank fixed on the base, and a water pump fixed on the base; the spray head and the water tank are connected by a hose.

[0015] Specifically, the detection mechanism includes a gas analyzer fixed on the top cover, a tubular moisture meter fixed on the baffle, and a distance sensor fixed on the top cover.

[0016] The beneficial effects of this invention are:

[0017] (1) The drive component can drive the box to move in four directions, making the planting box larger and giving the plants enough growing space.

[0018] (2) The spiral conveyor assembly can automatically transport the soil in the storage tank to the planting box, which can realize automatic soil replenishment.

[0019] (3) The soil distribution device can distribute the soil evenly during the soil replenishment process, and avoid the soil from accumulating on one side of the planting box.

[0020] (4) The linkage device works with the first sleeve and the protrusion on the bottom plate. During the movement of the first sleeve, the bottom plate can vibrate slightly, which can loosen the soil. Attached Figure Description

[0036] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Reference Figure 1-8 As shown, the plant cultivation experimental device for measuring greenhouse gas emissions from plants according to the present invention includes a base 1, a support 2 fixedly mounted on the base, multiple casters 3 fixedly mounted on the base, a top cover 4 rotatably mounted on the support, a planting mechanism 5 fixedly mounted on the support, a soil-filling mechanism 6 fixedly mounted on the base and the support, a spraying mechanism 7 fixedly mounted on the base and the top cover, an electrical control board 8 fixedly mounted on the base, and a detection mechanism 9 fixedly mounted on the planting mechanism and the top cover. The planting mechanism includes a second motor 51 fixedly mounted on the support, a first gear ring 52 rotatably mounted on the support, multiple drive components 53 slidably mounted on the support, a base plate 54 fixedly mounted on the support, multiple housings 55 slidably mounted on the base plate, a first slide groove 56 fixedly mounted on the housing, a baffle 57 slidably mounted on the first slide groove, and a limiting component 58 fixedly mounted on the baffle. The baffle and the base plate are connected by an elastic cloth 59.

[0038] The soil filling mechanism includes a storage tank 61 fixedly mounted on the base, a first through groove 62 fixedly mounted on the storage tank, a second sliding groove 63 fixedly mounted on the storage tank, a spiral conveying assembly 64 slidably mounted on the storage tank and passing through the bottom plate and the support, and a first motor 65 fixedly mounted on the base.

[0039] The second motor drives the first gear ring to rotate, which in turn causes the drive assembly to slide on the support, thus moving the boxes away from each other. During the movement of the boxes, the baffles that were originally slidably set in the first sliding groove are exposed. The baffles are used to cover the gaps created after the movement of the two adjacent boxes. At the same time, the movement of the boxes will also move the baffles together. The elastic cloth is used to cover the gaps between the baffles and the bottom plate after the boxes are moved, realizing the function of adjustable box size, so that the plants have enough growing space. When the size of the boxes is adjusted, the drive assembly will also drive the screw conveyor assembly to move upward a short distance. During the movement, the bottom plate and the box will vibrate slightly, realizing the function of loosening the soil. After the size of the boxes is adjusted, there is still space. The limiting component can prevent the plants from collapsing. At the same time, the first motor drives the screw conveyor assembly to work. The soil in the storage tank enters the screw conveyor assembly through the first channel and is sent to the box by the screw conveyor assembly, realizing the function of automatic soil replenishment. The screw conveyor assembly is equipped with a soil spreading device, which can spread the soil evenly in the box and prevent the soil from accumulating on one side of the box.

[0040] Specifically, the drive assembly includes a third slide groove 531 fixedly mounted on a bracket, a first connecting rod 532 slidably mounted on the third slide groove, a first gear 533 rotatably mounted on the bracket and meshing with a first gear ring, a second connecting rod 534 slidably mounted on the first connecting rod, a fourth slide groove 535 fixedly mounted on the second connecting rod, a third connecting rod 536 slidably mounted on the fourth slide groove, and a linkage device 537 fixedly mounted on the first connecting rod; the second connecting rod and the first connecting rod are connected by a first spring 538; one end of the third connecting rod is fixedly connected to the housing. The first connecting rod can slide on the third slide groove and has a threaded rod that meshes with the inner ring of the first gear; the second connecting rod can slide vertically on the first connecting rod; the fourth slide groove contains two third connecting rods, which are fixedly connected to two housings respectively; the linkage device is used to drive the screw conveyor assembly to move.

[0041] The second motor drives the first gear ring to rotate, the first gear ring to rotate, the first gear to rotate, the first gear to rotate, the first connecting rod to slide on the third slide groove, the first connecting rod to drive the second connecting rod to move together. Since each box is fixed to the connection of two third connecting rods, when the second connecting rod moves, the box will be subjected to two forces of equal magnitude and with an included angle of 90°, which will cause the box to move in a 45° oblique direction, making the box larger.

[0042] Specifically, the limiting component includes a spring telescopic rod 581 fixedly mounted on the baffle and an arc-shaped plate 582 fixedly mounted on the telescopic rod. The spring inside the spring telescopic rod is a compression spring; in the initial state, the arc-shaped plate is spliced ​​to form a partial spherical shape, which can clamp part of the soil and fix the plant in this part of the soil, preventing the plant from collapsing due to soil subsidence when the box expands or the soil is loosened.

[0043] Specifically, the spiral conveying assembly includes a first sleeve 641 slidably disposed on the storage tank and penetrating the bottom plate and the support, a second through groove 642 fixedly disposed on the first sleeve, a fifth slide groove 643 fixedly disposed on the first sleeve, a second gear 644 rotatably disposed on the base, a rotating shaft 645 fixedly disposed on the second gear, a first conveying rod 646 slidably disposed on the rotating shaft and rotatably disposed on the first sleeve, a soil spreading device 647 fixedly disposed on the conveying rod and rotatably disposed on the fifth slide groove, and a protrusion 648 fixedly disposed on the first sleeve and the bottom plate. The first sleeve can slide along the second chute, which is used to limit and prevent the first sleeve from rotating. The second chute is initially misaligned with the first chute on the storage tank. After the first sleeve moves, the second chute aligns with the first chute, allowing the soil in the storage tank to enter the first sleeve. The first conveying rod is equipped with spiral blades, which can transport soil when rotating. The first conveying rod is connected to the rotating shaft by splicing. When the first sleeve moves, it will drive the first conveying rod to move together. The first motor drives the second gear to rotate, which in turn drives the rotating shaft to rotate, causing the first conveying rod to rotate and transport the soil upward. After the soil moves upward, it will slide into the soil distribution device under the action of gravity due to the inclined angle of the spiral blades.

[0044] Specifically, the soil-spreading device includes a conical cover 6471 fixed to the conveying rod and rotatably mounted on the fifth chute, a first through hole 6472 fixed to the conical cover, a second sleeve 6473 fixed to the conical cover, a rack 6474 fixed to the second sleeve, a transmission wheel 6475 rotatably mounted on the fourth connecting rod and meshing with the rack, a second conveying rod 6476 fixed to the transmission wheel, and a plurality of second through holes 6477 fixed to the second sleeve. The conical cover can rotate on the fifth chute, and is fixedly connected to the first conveying rod. When the first sleeve moves upward, it drives the conical cover upward through the fifth chute, which in turn drives the first conveying rod upward. Soil enters the second sleeve through the first through hole. The second sleeve is provided with a chute, on which the drive wheel can rotate, driving the second conveying rod to rotate. The second sleeve is provided with a support block to prevent the drive wheel from rotating and causing the second sleeve to rotate. The outer side of the drive wheel meshes with a rack. When the first conveying rod rotates, it drives the conical cover to rotate, which in turn drives the second sleeve to rotate along the axis of the first conveying rod. The rotation of the second sleeve causes the drive wheel to roll on the rack, which in turn drives the second conveying rod to rotate, conveying the soil to the other end of the second sleeve. The second sleeve is provided with multiple second through holes, through which soil can fall out of the second sleeve.

[0045] Specifically, the linkage device includes a first rotating shaft bracket 5371 fixedly mounted on the first connecting rod, a second rotating shaft bracket 5372 fixedly mounted on the first sleeve, and a fourth connecting rod 5373 rotatably mounted on the first and second rotating shaft brackets. During movement, the first connecting rod drives the first rotating shaft bracket to move, which in turn causes the fourth connecting rod to rotate, pulling the second rotating shaft bracket, pressure plate, and first sleeve upwards. Since the protrusions on the bottom plate and the first sleeve are engaged at this time, the box, bottom plate, and first sleeve move upwards together. The second connecting rod slides on the first connecting rod, and simultaneously the first spring is stretched. After moving a certain distance, the combined force of the weight of the box, bottom plate, and soil, and the tension of the first spring, exceeds the maximum static friction between the protrusions on the bottom plate and the first sleeve. At this point, the protrusions on the bottom plate and the first sleeve will shift one position, i.e., the bottom plate moves downwards, causing the bottom plate and box to vibrate, thus loosening the soil.

[0046] Specifically, the spraying mechanism includes a spray head 71 fixedly mounted on the top cover, a water tank 72 fixedly mounted on the base, and a water pump 73 fixedly mounted on the base; the spray head and the water tank are connected by a hose 74. The spray head is used to spray water and fertilizer; the water tank can be removed to replenish water and fertilizer; the water pump and the water tank are connected by a hose.

[0047] Specifically, the detection mechanism includes a gas analyzer 91 fixedly mounted on the top cover, a tubular moisture meter 92 fixedly mounted on the baffle, and a distance sensor 93 fixedly mounted on the top cover. The gas analyzer is used to analyze oxygen, greenhouse gases, and aromatic gases inside the top cover and monitor these gases in real time. The moisture meter is used to monitor soil moisture content in real time, and the electronic control board can control the sprinkler heads to maintain the soil moisture content at a set value. The distance sensor is used to detect the height of the plants and judge the plant growth status based on the height. When a certain height is reached, the electronic control board will drive the planting mechanism to expand the box and control the soil replenishment mechanism to replenish soil.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
