[0001] The utility model relates to the technical field of tomato leaf moisture detection, in particular to a device for detecting the moisture content of tomato leaves based on hyperspectrum. Background Technique

[0002] In tomato planting, a device for detecting the moisture content of leaves is often used to detect the moisture content in its leaves, so as to judge whether the tomato grows healthily and cooperate with the staff to reasonably improve the planting method. For example, a rapid detector for the moisture content of crop leaves with the publication number of CN107328901A includes a detector base, a detection table and a detection table cover. The inner bottom end of the detection groove is fixedly provided with a detection disk through a main rotating shaft.

The dial is movably installed on the side wall of the detection groove through a side rotating shaft. A collection device is arranged in the detection table cover above the detection disk, and a display device is arranged on the detector base. When detecting, the leaf sample of the crop is placed on the detection table, and the leaf sample is located in the placement groove of the detection disk. The detection table is sealed by the detection table cover to ensure the accuracy of the detection. The detection disk can freely rotate in the detection groove through the main rotating shaft at the bottom end of the detection disk, so as to control the omnidirectional detection of the leaf sample. Among them, rotate the dial, and the detection disk rotates accordingly through the gear meshing structure between the dial and the external clamping teeth to complete the rotation of the leaf sample.

[0003] For the above-mentioned rapid detector for the moisture content of crop leaves, the detection table can be sealed by the detection table cover, and the leaf sampling can be conveniently completed. However, when detecting the moisture content of the leaves, when the staff place the leaves on the weighing instrument and dry the leaves, the leaves are easily blown up and offset by the hot air, which is not conducive to the subsequent detection.

[0012] Furthermore, a belt is nested at the rear end of the rotating rod, and the lower end of the belt is nested at the rear end of the air collecting plate.

[0013] Furthermore, the lower end of the traction rope is fixedly installed at the upper end of the lifting block. A sliding groove is formed in the inner wall of the housing, the lifting block is slidably connected with the sliding groove, a reset spring is fixedly installed inside the lifting block, a cleaning scraper is fixedly installed at the front end of the reset spring, the front end of the cleaning scraper is inclined, and the front end of the cleaning scraper is attached to the transparent part of the inner wall of the front end of the housing.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. A hyperspectral camera that is convenient for observation is provided. By arranging a hyperspectral camera at the bottom of the rotating door, the state of the blade during drying can be captured, which is convenient for subsequent staff to observe the blade state more carefully. At the same time, in cooperation with the transparent setting at the front end of the housing, the state of the blade during dehydration can be observed in a timely manner.

[0016] Further, when detecting the water content of tomato leaves, first weigh the tomato leaves with a weighing scale, and the weighed weight is displayed on the display screen for easy observation by the staff.

At the same time, as the traction rope is pulled, it can drive the lifting block to slide up and down along the sliding groove. When the lifting block rises along the sliding groove, the reset spring inside it presses on the cleaning scraper, and the cleaning scraper contacts the transparent position at the front end of the housing to scrape off the water vapor condensate beads, avoiding the situation of unclear observation and achieving the effect of facilitating observation.

Dryers 5 are arranged at the left and right ends of the housing 1, and the output ends of the dryers 5 are aligned with the leaf surfaces. A weighing device 7 is arranged inside the housing 1, and a display screen 8 is arranged at the front end of the weighing device 7, and the leaves are placed on the surface of the weighing device 7, and the front end of the housing 1 is made transparent.

[0030] In Embodiment 1, a hyperspectral camera 4 that is convenient for observation is provided. By arranging the hyperspectral camera 4 at the bottom of the rotating door 3, the state of the leaves during drying can be captured, which is convenient for subsequent staff to observe the leaf state more carefully. At the same time, in cooperation with the transparent setting at the front end of the housing 1, the state of the leaves during dehydration can be observed in a timely manner. When detecting the water content of tomato leaves, first weigh the tomato leaves through the weighing device 7, and the weighed weight is displayed on the display screen 8 for the convenience of the staff to observe. Then, dry the tomato leaves through the dryer 5, and weigh the dried tomato leaves. Therefore, subtracting the weight after drying from the weight before drying can obtain the water content of the tomato leaves. During drying, the generated gas is discharged through the air outlet 2.

[0031] Embodiment 2:

[0032] As Figures 1-4The disclosed technical solution is to solve the problem of poor drying effect, and it discloses that a driving motor is fixedly installed at the lower end of the housing 1, and the output end of the housing 1 rotates synchronously with the rotating disk 6 through a belt. The lower end of the rotating disk 6 is rotatably installed inside the housing 1, and an efficient drying detection mechanism is arranged on the outer side of the rotating disk 6. The efficient drying detection mechanism is provided with a rolling rod 9, and the upper end of the rolling rod 9 is fixedly installed at the lower end of the rotating disk 6. A circular groove 10 is opened on the bottom inner wall of the housing 1, and the rolling rod 9 is nested inside the circular groove 10. A limiting groove 13 is opened on the inner wall of the housing 1, and a baffle 11 is slidably connected inside the limiting groove 13. Air holes 12 are opened on the surface of the baffle 11, and the baffle 11 is located above the weighing device 7.

[0033] In the second embodiment, when drying tomato leaves, the motor at the bottom of the housing 1 drives the rotating disk 6 to rotate. When the rotating disk 6 rotates, it can drive the tomato leaves placed on the surface of the weighing device 7 at its upper end to be dried, so the drying effect can be improved. A rolling rod 9 is arranged at the lower end of the rotating disk 6, and the rolling rod 9 can rotate under the limitation of the circular groove 10 and support the rotating disk 6, so as to achieve the effect of improving stability and facilitate more comprehensive drying. When the tomato leaves are placed on the weighing device 7, by adjusting the baffle 11 back and forth, the baffle 11 can move back and forth along the limiting groove 13 for adjustment to limit the tomato leaves and prevent the tomato leaves from flying up when being dried by the blower 5 of the dryer, which can play a role in limiting the tomato leaves. At the same time, air holes 12 are opened on the surface of the baffle 11, which can achieve ventilation and avoid the baffle 11 blocking the drying, ensuring the drying efficiency of the device.

[0034] Embodiment Three:

[0035] Such as Figure 1 、 Figure 2 、 Figure 5 and Figure 6The disclosed technical solution, in order to solve the problem that the gas after drying is likely to condense into water droplets, resulting in unclear observation, discloses that: a wind collecting plate 14 is rotatably installed inside a housing 1, and the wind collecting plate 14 is located below the output end of a dryer 5. Moreover, an anti-fog mechanism is provided at the upper end of the wind collecting plate 14. The anti-fog mechanism is provided with a rotating rod 15, and the front and rear ends of the rotating rod 15 are rotatably installed inside the housing 1. And a wire winding wheel 16 is fixedly installed at the front end of the rotating rod 15. Moreover, a traction rope 17 is wound around the surface of the wire winding wheel 16. A belt is nested at the rear end of the rotating rod 15, and the lower end of the belt is nested at the rear end of the wind collecting plate 14. The lower end of the traction rope 17 is fixedly installed at the upper end of a lifting block 18. And a chute 21 is formed on the inner wall of the housing 1, and the lifting block 18 is slidably connected to the chute 21. Moreover, a return spring 19 is fixedly installed inside the lifting block 18. The front end of the return spring 19 is fixedly installed with a cleaning squeegee 20, and the front end of the cleaning squeegee 20 is inclined, and the front end of the cleaning squeegee 20 is attached to the transparent part of the front inner wall of the housing 1.

[0036] In the third embodiment, the wind blown out by the dryer 5 drives the wind collecting plate 14 to rotate. When the wind collecting plate 14 rotates, it rotates synchronously with the upper rotating rod 15 through the belt. Therefore, the rotation of the rotating rod 15 drives the wire winding wheel 16 at the front end to rotate, and winds the traction rope 17 around the surface of the wire winding wheel 16. At the same time, as the traction rope 17 is pulled, the lifting block 18 can be driven to slide up and down along the chute 21. When the lifting block 18 rises along the chute 21, the return spring 19 inside it presses on the cleaning squeegee 20, and the cleaning squeegee 20 contacts the transparent position at the front end of the housing 1, so as to scrape off the condensed water vapor beads, avoiding the situation of unclear observation and achieving the effect of facilitating observation.

[0037] The utility model is provided with a hyperspectral camera that can facilitate observation. By arranging a hyperspectral camera at the bottom of the rotating door, the state of the blade during drying can be captured, facilitating subsequent staff to observe the blade state more carefully. At the same time, in cooperation with the transparent setting at the front end of the housing, the state of the blade during dehydration can be observed in a timely manner. When detecting the water content of tomato leaves, first weigh the tomato leaves with a weighing device, and the weighed weight is displayed on the display screen for the convenience of the staff to observe. Then, dry the tomato leaves with a dryer and weigh the dried tomato leaves. Therefore, subtracting the weight after drying from the weight before drying can obtain the water content of the tomato leaves.

[0038] When drying tomato leaves, the motor at the bottom of the housing drives the rotating disk to rotate. When the rotating disk rotates, it can drive the tomato leaves placed on the weighing device on its upper end to be dried, so the drying effect can be improved. And a rolling rod is arranged at the lower end of the rotating disk. The rolling rod can rotate under the limitation of the circular groove and support the rotating disk, so as to achieve the effect of improving stability and facilitate more comprehensive drying. When the tomato leaves are placed on the weighing device, the front and rear adjusting baffle plates are adjusted. The baffle plates can move back and forth along the limiting grooves to limit the tomato leaves and prevent the tomato leaves from flying up when being dried by the air blown by the dryer, which can play a role in limiting the tomato leaves. At the same time, air holes are arranged on the surface of the baffle plates, which can achieve ventilation and avoid the baffle plates blocking drying, ensuring the drying efficiency of the device. The air blown by the dryer drives the air collecting plate to rotate. When the air collecting plate rotates, it rotates synchronously with the rotating rod at the upper end through the belt. Therefore, the rotation of the rotating rod drives the wire collecting wheel at the front end to rotate, and the traction rope is wound on the surface of the wire collecting wheel. At the same time, as the traction rope is pulled, the lifting block can slide up and down along the sliding groove. When the lifting block rises along the sliding groove, the reset spring inside it presses on the cleaning scraper, and the cleaning scraper contacts the transparent position at the front end of the housing, so as to scrape off the water vapor condensate beads and avoid the situation of unclear observation, achieving the effect of facilitating observation.
