[0031] Embodiment 1:
[0032] Referring to the attached Figures 1-3 , a tobacco leaf maturity detection device of this embodiment includes a housing 1. A handle 2 is fixedly connected to the bottom of the housing 1 for a staff member to hold the handle 2. A display screen 6 is fixedly connected to the top of the housing 1, and a controller 5 is fixedly connected to the top of the housing 1. The controller 5 is communicatively connected to the display screen 6. The controller 5 transmits the numerical value to the display screen 6, and the staff member views the data on the display screen 6 to obtain the chlorophyll content at different positions of the tobacco leaf to judge the maturity of the tobacco leaf. The model of the controller 5 is selected according to actual needs as long as it meets the work requirements. At one end of the housing 1 far from the handle 2, a first sensor 7 and a second sensor 8 are oppositely arranged. The distance between the first sensor 7 and the second sensor 8 is adjustable. Both the first sensor 7 and the second sensor 8 are chlorophyll sensors and are communicatively connected to the controller 5, so as to transmit the measured numerical value to the display screen 6 through the controller 5 for viewing.
[0033] Specifically, a second sensor 8 is arranged at one end of the housing 1 far from the handle 2. The second sensor 8 detects the tobacco leaf. The model of the second sensor 8 is selected according to actual needs as long as it meets the work requirements.
[0034] Inside the outer shell 1, there is a detection device for adjusting the distance between the first sensor 7 and the second sensor; the detection device includes a handle 11, a threaded column 12, a vertical column 13, a horizontal column 14, a vertical rod 15, a sleeve 16 and the first sensor 7. The bottom of the threaded column 12 penetrates through the outer shell and is fixedly connected to the handle 11. The staff rotates the handle 11, and the handle 11 drives the threaded column 12 to rotate. Preferably, the bottom outer wall of the threaded column 12 is rotationally connected to the inner wall of the outer shell 1 through a bearing. The top outer wall of the threaded column 12 is threadedly connected to the vertical column 13. The threaded column 12 drives the vertical column 13 to move. The top of the vertical column 13 is fixedly connected to the horizontal column 14. The vertical column 13 drives the horizontal column 14 to descend. The horizontal column 14 horizontally penetrates through the outer shell 1 and is movably connected to the outer shell 1. The horizontal column 14 can move up and down in the outer shell 1. On one side of the horizontal column 14 close to the vertical column 13, there is a vertical rod 15 fixedly connected. The horizontal column 14 drives the vertical rod 15 to move up and down. The outer wall of the vertical rod 15 is sleeved with a sleeve 16. The bottom of the sleeve 16 is fixedly connected to the inner wall of the outer shell 1. The two vertical rods 15 slide in the sleeve 16. On the side of the horizontal column 14 away from the vertical column 13 on the same side as the vertical column 13, there is a first sensor 7. The horizontal column 14 drives the first sensor 7 to descend. The model of the first sensor 7 is selected according to actual needs to meet the work requirements.
[0035] In the specific implementation process, it is particularly worth noting that the model of the controller 5 is selected according to actual needs to meet the work requirements; the model of the second sensor 8 is selected according to actual needs to meet the work requirements; the model of the first sensor 7 is selected according to actual needs to meet the work requirements. During operation, the staff holds the handle 2, and the second sensor 8 detects the tobacco leaves. The controller 5 transmits the values to the display screen 6. The staff observes the data on the display screen 6 to obtain the chlorophyll content at different positions of the tobacco leaves to judge the maturity of the tobacco leaves; then, the staff rotates the handle 11, and the handle 11 drives the threaded column 12 to rotate. Since the vertical column 13 is circumferentially fixed through the horizontal column 14, the vertical rod 15 and the sleeve 16, the threaded column 12 can only drive the vertical column 13 to move up and down. At the same time, the vertical column 13 drives the horizontal column 14 to descend. The horizontal column 14 moves in the outer shell 1. The horizontal column 14 drives the vertical rod 15 to move. The two vertical rods 15 slide in the sleeve 16. Moreover, the horizontal column 14 also drives the first sensor 7 to descend. The first sensor 7 and the second sensor 8 are arranged oppositely and are both in communication with the controller 5; by moving the handle, the first sensor 7 and the second sensor 8 are used to detect the chlorophyll content at different positions of the tobacco leaves, so as to detect the maturity of the tobacco leaves.
[0036] Further, the first sensor 7 is fixedly connected to the outer wall of the cross column 14 by bolts, and the second sensor 8 is fixedly connected to the inner wall of the housing 1 by bolts 9. In the specific implementation process, it is particularly noted that both the first sensor 7 and the second sensor 8 are chlorophyll sensors. The working principle of the chlorophyll sensor is mainly based on spectral analysis technology. By measuring the reflection and transmission of light of a specific wavelength by plant leaves, the chlorophyll content is evaluated. The staff can rotate the bolts 9 on the upper and lower sides to disassemble and replace the first sensor 7 and the second sensor 8.
[0037] Optionally, an anti-slip pad 3 is fixedly connected to the outer wall of the handle 2. When the staff holds the handle 2, the hand of the staff contacts the anti-slip pad 3, and the anti-slip pad 3 increases the friction of the handle 2 to prevent the staff from slipping when holding the handle 2.
[0038] A bottom plate 4 is also fixedly connected to the bottom of the handle 2. The bottom plate 4 limits the handle 2 so that the staff holds the middle position of the handle 2.
[0039] During operation, first, the hand of the staff contacts the anti-slip pad 3, and the anti-slip pad 3 increases the friction of the handle 2 to prevent the staff from slipping when holding the handle 2 again. The staff holds the handle 2, places the tobacco leaf between the first sensor 7 and the second sensor 8, and then the staff rotates the handle 11. The handle 11 drives the threaded column 12 to rotate, the threaded column 12 drives the vertical column 13 to move, the vertical column 13 drives the cross column 14 to descend, the cross column 14 moves in the housing 1, the cross column 14 drives the vertical rod 15 to move, the two side vertical rods 15 slide in the sleeves 16, the cross column 14 drives the first sensor 7 to descend, and the first sensor 7 and the second sensor 8 contact the tobacco leaf. After completion, the staff stops rotating the handle 11 and starts the first sensor 7 and the second sensor 8. Both the first sensor 7 and the second sensor 8 are chlorophyll sensors. Based on spectral analysis technology, by measuring the reflection and transmission of light of a specific wavelength by plant leaves, the chlorophyll content is evaluated; the first sensor 7 and the second sensor 8 transmit the information to the controller 5, and then through the controller 5 to the display screen 6. The staff views the data on the display screen 6 to obtain the chlorophyll content at different positions of the tobacco leaf to judge the maturity of the tobacco leaf. After the inspection is completed, the staff rotates the handle 11 in the reverse direction, and the first sensor 7 rises back to the initial position.
[0040] Embodiment 2:
[0041] Referring to Attach Figure 1 、 2 and 4, on the basis of Embodiment 1, a charging port 10 is installed on the front of the housing 1, and a bracket 17 is fixedly connected to the front of the housing 1. When the whole detection device is out of power, the whole detection device is charged through the charging port 10.
[0042] Optionally, a threaded rod 19 is threadedly connected to the top of the inner wall of the bracket 17. The top of the threaded rod 19 is fixedly connected to a rotary knob 18. The bottom of the threaded rod 19 is rotatably connected to a baffle 20 through a bearing. Both sides of the baffle 20 are slidably clamped in sliding grooves 21, and the two sliding grooves 21 are both opened on the inner wall of the bracket 17.
[0043] In the specific implementation process, it is particularly pointed out that when the overall charging of the detection device is completed, the staff rotates the rotary knob 18. The rotary knob 18 drives the threaded rod 19 to rotate. The threaded rod 19 drives the baffle 20 to move. The baffle 20 slides in the sliding groove 21, and the baffle 20 descends to block the charging port 10. After that, the staff stops rotating the rotary knob 18 to prevent dust from entering the inside of the charging port 10 and avoid the situation of poor contact of the charging port 10.
[0044] When the overall detection device is out of power, the staff rotates the rotary knob 18 in the reverse direction, thereby driving the baffle 20 to rise, exposing the charging port 10, and charging the overall detection device through the charging port 10.
