Description

Technical Field

[0001] The invention relates to the field of temperature measurement, and in particular to a pasture forage temperature detection device and a detection method for performing temperature detection at a special position of the forage. Background Art

[0002] Temperature monitoring of pasture forage is essential to ensure forage quality and the health of animal feeding. The temperature of forage can affect its nutritional content and microbial activity, which in turn affects livestock digestion and health.

[0003] In the related art, hay is stored in stacks. Since the density of each hay stack is different, the resistance encountered when the temperature probe is manually inserted into the hay stack is also different. When the resistance is too large, the temperature probe will bend and cannot reach the preset location. At the same time, since the density of the same hay stack is also different, the manual insertion method will cause excessive resistance in the previous second, and a larger insertion force will be manually applied. In the next second, the resistance suddenly decreases. At this time, due to the excessive insertion force, the inspection personnel will collide with the hay stack, which may cause the hay stack to collapse, resulting in casualties.

DETAILED DESCRIPTION

[0060] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0061] For examples, see Figure 1-Figure 4 At least one embodiment provides a pasture forage temperature detection device, comprising: a driving component 110 and a telescopic temperature measuring component 120; the driving component 110 is fixedly connected to the telescopic temperature measuring component 120 and is suitable for driving the telescopic temperature measuring component 120 to extend or retract; the telescopic temperature measuring component 120 comprises: an outer sleeve 121, a telescopic temperature measuring rod 122 and a screw 123; one end of the telescopic temperature measuring rod 122 extends into the outer sleeve 121 and is slidably connected to the outer sleeve 121; the driving component 110 is fixedly arranged on the outer sleeve 121; the screw 123 passes through the outer sleeve 121 and is rotatably connected to the telescopic temperature measuring rod 122; the driving component 110 is suitable for driving the screw 123 to rotate, thereby driving the telescopic temperature measuring rod 122 to extend and retract. By using the driving component 110 to control the telescopic speed of the telescopic temperature measuring rod 122, it is ensured that the telescopic temperature measuring rod 122 is inserted into the haystack at a constant speed, thereby preventing the haystack from collapsing. At the same time, the telescopic temperature measuring rod 122 is strengthened by the screw rod 123 to prevent the telescopic temperature measuring rod 122 from being deformed, thereby ensuring that the telescopic temperature measuring rod 122 can reach a preset temperature measuring point and improving the accuracy of temperature measurement.

[0062] like Figure 1 As shown, the driving assembly 110 includes a driving motor 111, a first gear (not shown) and a second gear (not shown), the first gear is sleeved on the screw 123 and is threadedly connected to the screw 123, the second gear is fixedly connected to the rotor of the driving motor 111, and the first gear is meshed with the second gear. When the driving motor 111 is working, it drives the second gear to rotate, and at this time the first gear also rotates, and the screw 123 threadedly connected to the first gear also rotates, and the screw 123 will rise and fall while rotating, thereby driving the telescopic temperature measuring rod 122 to extend or retract.

[0063] Please continue reading Figure 2 as well as Figure 4 , the structure of the telescopic temperature measuring rod 122 is described below. In at least one embodiment, the telescopic temperature measuring rod 122 includes: a temperature conducting tube 1221, a rotating bearing 1222 and a temperature measuring sensor 1223; the temperature conducting tube 1221 is slidably arranged in the outer sleeve 121; the rotating bearing 1222 is fixed to one end of the temperature conducting tube 1221 away from the outer sleeve 121, and the outer ring of the rotating bearing 1222 is fixedly connected to the inner wall of the temperature conducting tube 1221; one end of the screw 123 passes through the inner ring of the rotating bearing 1222, and the side wall of the screw is fixedly connected to the inner ring of the rotating bearing 1222; the temperature measuring sensor 1223 is fixedly arranged at one end of the screw 123 passing through the inner ring of the rotating bearing 1222. The screw 123 extends into the temperature conducting tube 1221 to support the temperature conducting tube 1221, thereby improving the strength of the temperature conducting tube 1221. At the same time, since there is a deviation in the temperature of the same point in the haystack at various positions, and the temperature sensor generally only detects the temperature in the facing direction, in some embodiments, the temperature sensor 1223 is fixed to the end of the screw 123. When the screw 123 rotates, the temperature sensor 1223 is also driven to rotate, so that the temperature sensor 1223 can detect the temperature of the entire circle of the temperature conducting tube 1221. By taking the temperature values ​​at different time points and obtaining the average value, the final temperature value is obtained to complete the temperature detection, thereby improving the accuracy of the temperature detection.

[0064] At the same time, in order to connect the wiring harness of the temperature sensor 1223, in the present application, a wiring harness hole 1231 is axially opened at the center of the screw 123, so as to facilitate the storage of the wiring harness of the temperature sensor 1223.

[0065] In order to control the telescopic rod to extend at a constant speed, in this embodiment, the pasture forage temperature detection device also includes a control module; the control module is electrically connected to the drive component 110 and is suitable for controlling the drive component 110 to drive the screw 123 to rotate at a constant speed.

[0066] Please continue reading Figure 2 as well as Figure 4 In this embodiment, at least two slide grooves 1211 are provided on the inner wall of the outer sleeve 121 along the axial direction; a slider 1221a is provided on the outer wall of the thermal conductive tube 1221 at a position corresponding to the slide groove 1211; and the slider 1221a is slidably disposed in the slide groove 1211. By providing the slide groove 1211 and the slider 1221a, the stability of the thermal conductive tube 1221 is enhanced.

[0067] In order to detect the extension distance of the telescopic temperature measuring rod 122, in at least one embodiment, a variable resistor is provided in one of the slide slots 1211 in the outer sleeve 121; the slider 1221a is made of metal, and the top surface of the slider 1221a is in contact with the variable resistor; the variable resistor and the slider 1221a constitute a sliding rheostat; the sliding rheostat is electrically connected to the control module; the control module is configured to adjust the output power w of the drive component 110 according to the resistance change Rt per unit time of the sliding rheostat, thereby controlling the screw 123 to rotate at a uniform speed. In the slide slots 1211 in the outer sleeve 121 where no variable resistor is provided, a conductive sheet is provided in one of the slide slots 1211; the variable resistor, the slider 1221a and the conductive sheet constitute a loop, and the control module is electrically connected to the loop to obtain the resistance change Rt. t By arranging the variable resistor and the conductive sheet in two different slide slots 1211, the connection of the sliding variable resistor is completed, the number of wiring in the outer sleeve 121 is reduced, and the overall stability of the system is improved.

[0068] Among them, according to the resistance change of the sliding rheostat per unit time R t The step of adjusting the output power W of the driving component 110 is: configuring a preset resistance change R per unit time. 预设 ; When the control module receives the resistance change R per unit time of the sliding rheostat t Less than R 预设 When the control module receives the resistance change R per unit time of the sliding rheostat, the output power W of the driving component 110 is reduced; t Greater than R 预设 When the output power W of the driving component 110 is increased. 预设 When the drive assembly 110 outputs the preset output power Wpreset under the average density of the haystack, the maximum resistance value R of the sliding rheostat is max divided by the time t when the telescopic temperature measuring rod 122 is fully extended 测 Specifically, the output power W is adjusted by adopting a feedback adjustment method.

[0069] like Figure 3 As shown, in this embodiment, the thermal conductive tube 1221 is made of a heat-conducting material. The outer wall of the thermal conductive tube 1221 is provided with a liquid retention groove 1221b along the axial direction; the cross section of the liquid retention groove 1221b is in the shape of a water drop. There are multiple liquid retention grooves 1221b; multiple liquid retention grooves 1221b are arranged along the circumference of the thermal conductive tube 1221. By providing the liquid retention groove 1221b, the liquid accumulated in the haystack is collected, which is convenient for subsequent detection of the pH value and nutritional components in the liquid, and analysis of the storage, fermentation and quality of the hay.

[0073] It should be noted that when the telescopic temperature measuring assembly 120 is extended at a constant speed, the temperature sensor 1223 rotates along with the rotation of the screw 123, so that the temperature sensor 1223 can detect the temperature of the entire temperature conducting tube 1221, and obtain the final temperature value by averaging to complete the temperature detection.

[0074] S130: Control the driving component 110 to operate, so that the telescopic temperature measuring component 120 contracts to complete the measurement.
