Optionally, the specific distance between one end of the scraping plate 413 close to the feeding belt 300 and the feeding belt 300 is determined according to the thickness of the material, and the distance between the scraping plate 413 and the feeding belt 300 is adjustable. The specific adjustment mode can be as follows:

as shown in fig. 4, the mounting bracket 600 includes two vertical brackets 62, a first horizontal bracket 61 and a second horizontal bracket 63, the two vertical brackets 62 are respectively fixed at two ends of the feeding bracket 500 in the width direction, two ends of the first horizontal bracket 61 and the second horizontal bracket 63 are respectively fixed on the two vertical brackets 61, and the second horizontal bracket 62 is located above the first horizontal bracket 61. Wherein, the material leveling device 41 is fixed on the first horizontal bracket 61, and the moisture meter 42 is fixed on the second horizontal bracket 62.

the sensors are in communication with the controller, which is in communication with the sensors and moisture meter 42, respectively, and the sensors are configured to detect whether the material is being leveled by material leveling device 41.

Specifically, fig. 5 is another schematic structural diagram of the material moisture content detection device 400 provided by the present application, as shown in fig. 5, the detector is a micro switch 43, wherein the micro switch 43 is disposed inside the scraping plate 413, wherein the inside of the scraping plate 413 refers to a side surface (an area surrounded by the scraping plate 413, the first side plate 411, and the second side plate 412) of the scraping plate 413, which is close to the first area Q, wherein the controller is in communication connection with the micro switch 43 and the moisture meter 42, and the micro switch 43 is configured to detect whether the material is leveled. The controller is in communication connection with the micro switch 43 and the moisture meter 42; wherein, micro-gap switch 43 is used for generating material flattening signal to send material flattening signal to the controller, the controller with material flattening signal transmission to moisture meter 42, moisture meter 42 is according to the moisture content of the material of material flattening device flattening back of material flattening signal detection. Alternatively, as shown in fig. 5, when the scraper plates 413 include two first scraper plates 414, the micro-switch 43 is disposed at an intermediate position inside one of the first scraper plates 414.

Specifically, as shown in fig. 5, the microswitch 43 includes: a microswitch body 431; a contact piece 432 (e.g. a spring piece) with one end fixed on the microswitch body 431, wherein the other end of the contact piece 432 is a free end, the free end is close to the material conveying belt 300, and the extending direction of the contact piece 432 is perpendicular to the material conveying belt 300; and contacts disposed on the contact pads 432, wherein the contacts include a fixed contact and a movable contact. Contact 432 can be stirred when the material is through scraping flitch 413, and when contact 432 was stirred by the material, the movable contact put through with decide the contact fast, and micro-gap switch 43 put through promptly can think: the material is leveled by the material leveling device, that is, when the contact 432 is shifted by the material, the micro switch 43 generates a material leveling signal and transmits the material leveling signal to the controller, the controller transmits the material leveling signal to the moisture meter 42, and the moisture meter 42 starts the detection operation after receiving the material leveling signal and after a preset time. This application uses micro-gap switch 43 as detecting whether the material is by the flattening, because micro-gap switch 43 passes through contact 432 can be closed, micro-gap switch 43 can produce material flattening signal, and micro-gap switch 43's simple structure easily realizes.

For example: the distance l2 between the one end of the scraping plate 413 close to the material conveying belt 300 and the material conveying belt 300 is 7cm, when the thickness of the material on the material conveying belt 300 is larger than or equal to 7cm, when the scraping plate 413 scrapes the material at ordinary times, the thickness of the scraped material is 7cm, the thickness of the scraped material is consistent, at the moment, after the contact piece 432 in the micro switch 43 is touched, the thickness of the material in the detection area is consistent, then a material leveling signal is generated, the micro switch 43 transmits the material leveling signal to the moisture determinator 42, after the moisture determinator 42 receives the material leveling signal, the detection work is started after a preset time, and the probability of inaccurate detection result caused by inconsistent material thickness in the detection area is reduced.

Specifically, the moisture meter 42 starts to operate after receiving the material leveling signal for a preset time period, where the preset time period may be determined according to the position of the microswitch 43 on the scraper 413, the distance between the scraper 413 and the moisture meter 42, and the information of the conveying parameters (such as the linear speed of the conveying belt 300) of the conveying belt 300 for conveying the material. For example, on the premise that the distance between the scraper 413 and the moisture meter 42 and the information of the conveying parameters of the material conveyed by the conveying belt 300 are fixed, the closer the micro switch 43 is disposed on the scraper 413 to the moisture meter 42, the shorter the preset time period.

Specifically, because the types of the materials conveyed by the conveying belt 300 are different, when the moisture content of the materials is detected, the moisture meter 42 selects a detection channel corresponding to the type of the materials according to the type of the materials to detect the moisture content of the materials, so as to obtain the current moisture content of the materials; and then selecting a proper water content correction model according to the material type to select a proper correction coefficient, and correcting the current water content according to the correction coefficient to obtain the final water content of the material, namely the water content of the material. When the type of the material conveyed by the material conveying belt 300 is determined, the specific material type of the material conveyed by the material conveying belt 300 is determined according to the distance between the material bin 100 and the scraper 413, the linear speed of the material conveying belt 300 and the material unloading signal. The detector may be not only the microswitch 43 described above but also other detection devices such as an imaging device. And the installation position of the detector can be determined according to the specific type of the detector, and can be installed on the material leveling device or other positions. For example, when the detector is a microswitch 43, the microswitch 43 is mounted inside the scraper plate.

In one possible implementation, as shown in fig. 6, the moisture meter 42 includes: a microwave emitter (not shown in fig. 6) disposed below the feeding belt 300 is configured to emit microwaves; the moisture meter probe 421 is fixed on the mounting bracket 600, the moisture meter probe 421 is arranged above the material conveying belt 300, and the moisture meter probe 421 is configured to receive microwaves transmitted by the microwave transmitter and passing through the material and the residual microwaves after the microwaves pass through the material conveying belt 300; and signal receiver 422, signal receiver 422 sets up the below at defeated material belt 300, and signal receiver 422 configures as: detecting the moisture content of the material according to the microwave emitted by the microwave emitter and the residual microwave received by the moisture meter probe 421; wherein, the detection area of the moisture meter probe 421 on the feeding belt 300 at least partially overlaps with the first area. This application utilizes the microwave to detect the moisture content in the material promptly, and its theory of operation is: when microwaves with specific frequency of 2.4GHz penetrate through the material on the material conveying belt 300, 0-H bonds of water molecules in the material can absorb microwave energy with specific frequency. Microwave energy emitted by the microwave emitter penetrates through the material and the belt, and the remaining microwave energy is received by the moisture meter probe 421. The signal receiver 422 calculates the percentage content of moisture, i.e. the water content of the material, based on the microwave energy attenuation generated when the microwaves penetrate the medium.

Optionally, a straight line between the moisture meter probe 421 and the central point of the first area is perpendicular to the feeding belt 300. Moisture meter probe 421 is located material leveling device 41 directly over promptly, when moisture meter probe 421 sends the microwave, the microwave can pierce through the material in the first region, and then the material that moisture meter 42 detected is most to be located the material in the first region, and the material that moisture meter 42 detected promptly is the material after being leveled mostly, because the material in the first region is leveled, the thickness uniformity, consequently, the degree of accuracy of the moisture content of the material that material moisture content detection device detected has been improved.

In the concrete production and transportation process, when the material conveying belt 300 conveys materials, the transportation environment is mostly severe, so that a large amount of dust is easily attached to the moisture meter probe 421 of the moisture meter 42, and the accuracy of the measured data is seriously affected.
