Description

Technical Field

[0001] The invention belongs to the field of wheat root system detection, in particular to a wheat root system detection sampling and separation device. Background Art

[0002] Plant root system testing is an important agricultural and ecological research field. It can help us understand the growth dynamics, structure and function of plant roots, thereby optimizing plant growth conditions and increasing crop yields. The purpose of wheat root system testing is to deeply understand the growth and development mechanism of wheat roots and how it affects crop growth and development, yield formation and tolerance to abiotic stresses.

[0003] A patent application with publication number CN112305157A discloses a plant root growth detection device, which belongs to the field of plant growth monitoring technology. A plant root growth detection device includes a cup sleeve, a cup body, a cup cover and a measuring cylinder. The cup sleeve includes an inner wall, an outer wall and an upper wall. The space separated by the inner wall, the outer wall and the upper wall is a liquid cavity. The liquid cavity is filled with liquid, which can protect the plant root system from being affected by external light. It can indirectly observe the root growth of the plant in all directions in the cup body.

[0004] Traditional wheat root system testing requires pulling the growing wheat out of the soil, but root system testing requires a relatively complete root system. However, the wheat root system is closely integrated with the soil, and direct and forceful pulling out can easily cause root damage.

[0005] To this end, the present invention provides a wheat root system detection sampling and separation device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: a wheat root detection sampling and separation device described in the present invention comprises a recovery tank, a recovery hole is provided in the middle of the bottom surface of the recovery tank, a negative pressure machine is provided on the outside of the recovery tank, the negative pressure generating end of the negative pressure machine is connected to the top of the recovery hole, a grabbing component is provided on the inside of the recovery hole, the grabbing component is used to pull the wheat out of the land by the roots, a plurality of optical cameras are installed on the inner wall of the recovery hole, an annular driving groove is provided at the bottom of the recovery tank, and a plurality of separation blocks for separating wheat and soil are provided in the driving groove;

[0008] When you need to randomly pick a few wheat plants from a wheat field for testing, by observing the root conditions of the wheat, you can deeply understand the growth and development mechanism of the wheat root system, and you can also detect whether the wheat roots are diseased. However, the wheat roots are closely connected to the soil. If you pull them out directly, it is easy for some roots to remain in the soil, resulting in inaccurate detection structure.

[0009] Through the setting of the recovery tank, the operator holds the recovery tank, selects a wheat plant, and aims the recovery hole at the bottom of the recovery tank from top to bottom at the wheat. At the same time, the negative pressure machine is started to generate negative pressure, and the negative pressure is transmitted to the recovery hole. Under the adsorption of negative pressure, the upper part of the wheat will be sucked into the recovery hole under the action of negative pressure, so that the recovery tank will not press on the leaf part of the wheat during the downward pressure process. After the recovery tank contacts the ground, the grabbing component will grab the stems of the wheat close to the ground, and then the separation block will be inserted into the ground to vibrate and loosen the soil around the wheat. At the same time, the grabbing component slowly pulls the wheat upward, greatly reducing the problem of root damage caused by forced pulling out of wheat. After the wheat is completely separated from the soil and placed in the recovery tank, multiple optical cameras are used to take photos of the wheat roots and the whole. Through this setting, not only the wheat is completely removed from the soil, the damage to the wheat roots is reduced, but also all the appearance information of the wheat is recorded. No on-site observation is required. After randomly sampling multiple wheats, the data can be fully analyzed.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 3 As shown, a wheat root detection sampling and separation device according to an embodiment of the present invention comprises a recovery tank 1, a recovery hole 9 is provided in the middle of the bottom surface of the recovery tank 1, a negative pressure machine 5 is provided on the outside of the recovery tank 1, a negative pressure generating end of the negative pressure machine 5 is connected to the top of the recovery hole 9, a grabbing component is provided on the inside of the recovery hole 9, and the grabbing component is used to pull wheat out of the soil by the roots, a plurality of optical cameras 13 are installed on the inner wall of the recovery hole 9, an annular driving groove 10 is provided at the bottom of the recovery tank 1, and a plurality of separation blocks 8 for separating wheat and soil are provided in the driving groove 10;

[0033] When you need to randomly pick a few wheat plants from a wheat field for testing, by observing the root conditions of the wheat, you can deeply understand the growth and development mechanism of the wheat root system, and you can also detect whether the wheat roots are diseased. However, the wheat roots are closely connected to the soil. If you pull them out directly, it is easy for some roots to remain in the soil, resulting in inaccurate detection structure.

[0034] Through the setting of the recovery tank 1, the operator holds the recovery tank 1, selects a wheat plant, and aligns the recovery hole 9 at the bottom of the recovery tank 1 from top to bottom with the wheat, and at the same time starts the negative pressure machine 5 to generate negative pressure, and the negative pressure is transmitted to the recovery hole 9. Under the adsorption of the negative pressure, the upper part of the wheat will be sucked into the recovery hole 9 under the action of the negative pressure, so that the recovery tank 1 will not press the leaf part of the wheat during the downward pressing process. After the recovery tank 1 contacts the ground, the grabbing component will clamp the wheat stem close to the ground, and then the separation block 8 will be inserted into the ground to vibrate and loosen the soil around the wheat. At the same time, the grabbing component slowly pulls the wheat upward, greatly reducing the problem of root damage caused by forced pulling out of the wheat. After the wheat is completely separated from the soil and enters the recovery tank 1, multiple optical cameras 13 are used to take photos of the wheat root system and the whole. Through this setting, not only the wheat is completely taken out of the soil, the damage to the wheat root system is reduced, but also all the appearance information of the wheat is recorded. There is no need for on-site observation. After randomly sampling multiple wheats, the data can be fully analyzed.

[0035] It should be noted that the root system detection of wheat is mainly in the "tillering stage, greening stage, jointing stage and heading stage" in the wheat growth cycle, because the root system detection of wheat is to analyze the growth dynamics and growth and development mechanism of wheat. In these four cycles, wheat has not yet fully grown and formed, and the planting interval of wheat is generally 15 to 20 centimeters. In order to facilitate the management of wheat fields, a 20-centimeter wide row is left between each sowing width, so the recovery tank 1 can smoothly cover the wheat from top to bottom.

[0036] like Figures 1 to 5 As shown, a plurality of electric telescopic rods 14 are arranged inside the driving slot 10, the bottom output end of the electric telescopic rod 14 is fixedly connected to the separation block 8, the plurality of electric telescopic rods 14 are distributed in an annular shape with equal spacing, and a power assembly is arranged between the outer sides of the plurality of electric telescopic rods 14, and the power assembly is used to drive the plurality of electric rods 14 to rotate in an annular shape;

[0037] During operation, after the recovery tank 1 contacts the ground, the electric telescopic rod 14 is started to push the separation block 8 downward. The bottom and sides of the separation block 8 are flat, which can effectively break the soil. At the same time, the power component allows multiple electric telescopic rods 14 and the separation block 8 to rotate, so that a circular ring can be drawn around the wheat root system. In this way, even if the soil dries up and the wheat roots are closely combined with the soil, the grabbing arm 12 can directly lift the wheat and the soil because the surrounding soil is divided. Then, the grabbing component shakes the wheat up and down to shake off the remaining soil from the wheat root system, thereby obtaining a complete wheat root system.

[0038] like Figures 1 to 7 As shown, the power assembly includes a gear ring 15, the gear ring 15 is slidably engaged in the recovery tank 1, the outer side of the gear ring 15 is meshed with a transmission gear 20, the transmission gear 20 is located on the outer side of the recovery tank 1, a reduction motor 19 is provided on one side of the transmission gear 20, a transmission belt 21 is connected between the output end of the reduction motor 19 and the central axis of the transmission gear 20, and a protective shell 11 is sleeved on the outer sides of the transmission gear 20 and the reduction motor 19;

[0039] During operation, the reduction motor 19 rotates, and the transmission belt 21 drives the transmission gear 20 to rotate, and the transmission gear 20 drives the gear ring 15 to rotate, thereby completing the rotation of all the electric telescopic rods 14 and the separation block 8. Since the reduction motor 19 and the transmission gear 20 are transmitted through the transmission belt 21, even if the soil is hard, only the transmission belt 21 will slip, and the reduction motor 19 will not stop suddenly, thereby reducing the damage of the reduction motor 19.

[0040] like Figures 1 to 7 As shown, the outer side of the electric telescopic rod 14 is sleeved with a connecting arm 18, and a plurality of vertically arranged springs are fixedly connected between the outer side of the electric telescopic rod 14 and the connecting arm 18. The top of the recovery hole 9 is provided with an extrusion assembly, and the extrusion assembly includes a plurality of extrusion blocks 17 for extruding the electric telescopic rod 14;

[0041] During operation, during the rotation of the electric telescopic rod 14, the top of the electric telescopic rod 14 will continuously contact the extrusion block 17. Since the electric telescopic rod 14 and the connecting arm 18 are connected by a spring, the electric telescopic rod 14 will reciprocate up and down, thereby assisting the separation block 8 in breaking the soil.

[0042] like Figures 1 to 7 As shown, a series ring 16 is fixedly connected to the top of the recovery hole 9, and a plurality of extrusion blocks 17 are fixedly connected to the bottom of the series ring 16. The extrusion blocks 17 are hemispherical in shape, and the plurality of extrusion blocks 17 are equidistantly arranged in a ring shape;

[0043] During operation, when the electric telescopic rod 14 makes a circular motion, the top will be squeezed by multiple extrusion blocks 17 arranged at equal intervals. When encountering the extrusion block 17, the electric telescopic rod 14 sinks, and when away from the extrusion block 17, the electric telescopic rod 14 rises under the action of the spring, and cooperates with the hemispherical setting of the extrusion block 17 to reduce the resistance generated during the extrusion process. Through this setting, the movement mode of the separation block 8 is increased, and the ground-breaking ability of the separation block 8 is effectively improved without the need to add a new power source.

[0044] like Figures 1 to 7 As shown, the grabbing assembly includes a plurality of grabbing arms 12, which are arranged in a circular and equidistant manner. The grabbing arm 12 is composed of an electric telescopic rod 24 and an extrusion head 26. A driving seat 25 is fixedly connected to the inner wall of the recovery hole 9. The moving end of the driving seat 25 is fixedly connected to one end of the electric telescopic rod 24, and the extrusion head 26 is fixedly connected to the other end of the electric telescopic rod 24.

[0045] During operation, a driving motor is arranged inside the driving seat 25, and the outer side of the output end of the driving motor is fixedly connected to one end of the electric telescopic rod 24, so that the rotation angle of the electric telescopic rod 24 can be adjusted, and the electric telescopic rod 24 can be extended at the same time. When grabbing wheat, multiple grabbing arms 12 rotate downward, and the electric telescopic rod 24 extends at the same time, and the ends of multiple electric telescopic rods 24 are closed together to grab the roots of the wheat exposed on the ground, and then the electric telescopic rod 24 is slowly rotated. Under the premise of maintaining the grabbing force, the electric telescopic rod 24 is shortened, so that the process of slowly pulling up the wheat is realized, and the shaking process of the wheat can also be achieved by quickly adjusting the angle of the electric telescopic rod 14. Through this arrangement, the functions of grabbing and lifting the wheat are simply and conveniently completed.

[0046] like Figures 1 to 7 As shown, a control arm 3 is provided on the top of the recovery tank 1, and the control arm 3 is connected to the recovery tank 1 through a rotating shaft 2;

[0047] During operation, the operator holds the control arm 3. A control panel is installed on the top of the control arm 3 to adjust various electrical components in the recovery tank 1. At the same time, the rotating shaft 2 can adjust the angle of the control arm 3 and the recovery tank 1. In this way, the operator only needs to stand normally to complete the sampling of wheat, which reduces the difficulty of operation.

[0048] like Figures 1 to 7 As shown, a transfer hole is provided on the outside of the recovery tank 1, a recovery box 4 is fixedly connected to the outside of the transfer hole, the recovery box 4 and the recovery tank 1 are connected to each other, a transfer plate 23 that can be translated is provided on the inside of the recovery tank 1, the negative pressure machine 5 is fixedly connected to the outside of the recovery box 4, and the negative pressure machine 5 has two output ends, one of which is connected to the inside of the recovery tank 1 through a pipeline, and the other is connected to the recovery box 4;

[0049] During operation, the wheat can be recycled after being photographed. When the wheat is transferred upward to the highest point by the grabbing arm 12, the other output end of the negative pressure machine 5 generates negative pressure and transmits it to the recycling box 4, and closes the negative pressure connected to the recycling tank 1, so that the negative pressure will pull the wheat toward the recycling box 4. In order to ensure smooth transfer, the translatable transfer plate 23 will press the part above the wheat root system toward the recycling box 4 during the translation process. At the same time, the multiple electric telescopic rods 24 are shortened to release the wheat, so that the wheat can be transferred to the recycling box 4, completing the wheat recycling process.

[0050] like Figures 1 to 7 As shown, a plurality of through holes are provided on the surface of the transfer plate 23, and both sides of the transfer plate 23 are slidably engaged with both sides of the inner wall of the recovery tank 1, and both sides of the inner wall of the recovery tank 1 are installed with a lead screw nut mechanism 22, and the sliding nut of the lead screw nut mechanism 22 is fixedly connected with the transfer plate 23;

[0051] During operation, the transfer plate 23 is driven to move by the screw nut mechanism 22, and the through holes on the surface of the transfer plate 23 allow the negative pressure to be transmitted normally when squeezing wheat.

[0052] like Figures 1 to 7 As shown, the top of the recycling box 4 is provided with a plurality of through holes, and an isolation plate 6 is slidably connected in the through holes, and the plurality of through holes are arranged at equal intervals, and a plurality of vent holes are provided on the surface of the isolation plate 6, and electric wheels are installed on both sides of the through holes near the top, and the electric wheels are drivingly connected to the outer side of the isolation plate 6, and one side of the recycling box 4 is provided with an opening, and a recycling door 7 is rotatably connected to the opening;

[0053] During operation, after the wheat is adsorbed into the recycling box 4, the electric wheel is started to drive the isolation plate 6 closest to the negative pressure machine 5 to sink, and the adsorbed wheat is stored separately. The subsequent wheat is isolated one by one by the isolation plate 6. The through holes on the isolation plate 6 allow the negative pressure to be transmitted normally, and the wheat is subsequently taken out through the recycling door 7. Through this setting, the wheat corresponding to the photo can be found, which is convenient for the subsequent continued detection process.

[0054] During operation, through the setting of the recovery tank 1, the operator holds the recovery tank 1, selects a wheat plant, and aligns the recovery hole 9 at the bottom of the recovery tank 1 from top to bottom with the wheat, and at the same time starts the negative pressure machine 5 to generate negative pressure, and the negative pressure is transmitted to the recovery hole 9. Under the adsorption of the negative pressure, the upper part of the wheat will be sucked into the recovery hole 9 under the action of the negative pressure, so that the recovery tank 1 will not press the leaf part of the wheat during the downward pressing process. After the recovery tank 1 contacts the ground, multiple grab arms 12 will clamp the root position of the wheat exposed above the ground, and then the separation block 8 will be inserted into the ground to vibrate and loosen the soil around the wheat. At the same time, the grab arm 12 slowly pulls the wheat upward, greatly reducing the problem of root damage caused by forced pulling out of the wheat. After the wheat is completely separated from the soil and enters the recovery tank 1, multiple optical cameras 13 are used to take photos of the wheat root system and the whole. Through this setting, not only the wheat is completely taken out of the soil, the damage to the wheat root system is reduced, but also all the appearance information of the wheat is recorded. There is no need for on-site observation. After randomly sampling multiple wheats, the data can be fully analyzed;

[0055] When the recovery tank 1 contacts the ground, the electric telescopic rod 14 is started to push the separation block 8 downward. The bottom and side of the separation block 8 are flat, which can effectively break the soil. At the same time, the power component rotates the gear ring 15, and then the multiple electric telescopic rods 14 and the separation block 8 rotate, so that a circular ring can be drawn around the root system of the wheat. In this way, even if the soil dries up and the wheat roots are closely combined with the soil, the grabbing arm 12 can directly lift the wheat and the soil because the surrounding soil is divided. Then, by shaking the grabbing arm 12 up and down, the remaining soil can be shaken off the wheat root system, so as to obtain a complete wheat root system;

[0056] The reduction motor 19 rotates, and the transmission belt 21 drives the transmission gear 20 to rotate, and the transmission gear 20 drives the gear ring 15 to rotate, thereby driving all the electric telescopic rods 14 and the separation block 8 to rotate. Since the reduction motor 19 and the transmission gear 20 are transmitted through the transmission belt 21, even if the soil is hard, only the transmission belt 21 will slip, and the reduction motor 19 will not stop suddenly, thereby reducing the damage to the reduction motor 19;

[0057] During the rotation of the electric telescopic rod 14, the top of the electric telescopic rod 14 will continuously contact the squeezing block 17. Since the electric telescopic rod 14 and the connecting arm 18 are connected by a spring, the electric telescopic rod 14 will reciprocate up and down, thus assisting the separation block 8 in breaking the soil.

[0058] When the electric telescopic rod 14 performs circular motion, the top portion will be squeezed by a plurality of equally spaced squeezing blocks 17. When encountering the squeezing blocks 17, the electric telescopic rod 14 sinks. When away from the squeezing blocks 17, the electric telescopic rod 14 rises under the action of the spring. The hemispherical setting of the squeezing blocks 17 is used to reduce the resistance generated during the squeezing process. This setting increases the movement mode of the separation block 8, effectively improving the earth-breaking ability of the separation block 8, and does not require the addition of a new power source.

[0059] A driving motor is arranged inside the driving seat 25, and the outer side of the output end of the driving motor is connected to the electric telescopic rod 24, so that the rotation angle of the electric telescopic rod 24 can be adjusted, and the electric telescopic rod 24 can be extended at the same time. When grabbing wheat, multiple grabbing arms 12 rotate downward, and the electric telescopic rod 24 is extended at the same time. The ends of multiple electric telescopic rods 24 are closed together to grab the roots of wheat exposed on the ground, and then the electric telescopic rod 24 is slowly rotated. Under the premise of maintaining the grabbing force, the electric telescopic rod 24 is shortened, so that the process of slowly pulling up the wheat is realized. The shaking process of the wheat can also be achieved by quickly adjusting the angle of the electric telescopic rod 14. Through this arrangement, the functions of grabbing and lifting the wheat are simply and conveniently completed;

[0060] The operator holds the control arm 3, and a control panel is installed on the top of the control arm 3 to adjust various electrical components in the recovery tank 1. At the same time, the rotating shaft 2 can adjust the angle of the control arm 3 and the recovery tank 1. In this way, the operator only needs to stand normally to complete the wheat sampling work, which reduces the difficulty of operation;

[0061] After the wheat is photographed, it can be recycled. When the wheat is transferred upward to the highest point by the grabbing arm 12, the other output end of the negative pressure machine 5 generates negative pressure and transmits it to the recycling box 4, and closes the negative pressure connected to the recycling tank 1, so that the negative pressure will pull the wheat toward the recycling box 4. In order to ensure the smooth transfer, the transfer plate 23 that can be translated will press the part above the wheat root system toward the recycling box 4 during the translation process, and at the same time, the multiple electric telescopic rods 24 are shortened to release the wheat, so that the wheat can be transferred to the recycling box 4, completing the wheat recycling process;

[0062] The transfer plate 23 is driven to move by the lead screw nut mechanism 22, and the through holes on the surface of the transfer plate 23 are provided so that the negative pressure can be normally transmitted when squeezing the wheat;

[0063] When the wheat is adsorbed into the recycling box 4, the electric wheel is started to drive the isolation plate 6 closest to the negative pressure machine 5 to sink, and the adsorbed wheat is stored separately. The wheat is then isolated one by one by the isolation plate 6. The through holes on the isolation plate 6 allow the negative pressure to be transmitted normally, and the wheat is subsequently taken out through the recycling door 7. Through this setting, the wheat corresponding to the photo can be found, which is convenient for the subsequent continued detection process.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
