Description

Technical Field

[0001] The utility model belongs to the technical field of rice processing equipment, and particularly relates to a rice moisture detection device. Background Art

[0002] Moisture content is a key indicator of rice quality. The national standard "Rice" (GB / T1354-2018) recommends a moisture content of ≤14.5% for high-quality glutinous rice and ≤15.5% for high-quality polished round-grained rice. Therefore, moisture testing is necessary during rice processing. Traditional moisture testing methods, such as the dry weight method, calculate moisture content based on the change in weight before and after drying. However, this method requires drying the rice to a constant weight, which is cumbersome and time-consuming.

[0003] Chinese patent document CN209215272U discloses a rice moisture detection device, which includes a housing, a display, control buttons, a switch, a power supply, a probe, a data storage and transmission device, and a capacitance-to-digital converter. The upper right end of the housing is plugged into the probe via a power cord, and the upper left end of the housing is provided with the data storage and transmission device. The rice moisture detection device of the utility model is provided with a probe, a rear insulating bracket and a front insulating bracket sandwiching a left metal electrode and a right metal electrode, and affixing them together with strong glue to form an integral body, so that the left metal electrode and the right metal electrode are completely isolated from the air, forming a measurable probe, achieving the purpose of simple manufacture and simple structure. By providing the data storage and transmission device, the measured data can be processed by a data processor and stored in a memory. When sorting, the data can be imported into a computer terminal via a GPRS communication device, achieving the purpose of simple and fast data sorting and error-prone recording.

[0004] However, when using the above-mentioned moisture detection device, an operator needs to hold the electrode for detection, which is inconvenient to operate. Moreover, due to the length limitation of the electrode, it is not convenient to detect the moisture content inside the rice outside the length range of the electrode. Utility Model Content

[0013] Furthermore, the longitudinal projection of the discharge port is not located on the support plate.

[0014] Furthermore, the moisture detection device further includes: a controller, which is provided on the box body and is connected to the rotating device, the detecting element, the lifting device, and the vibration device.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1.

[0029] There is a door on the feeding port, which is opened when adding materials and closed when the moisture is detected; the box door can be hinged to the box body and is closed during operation.

[0030] The rotating device can be a motor. When the motor is running, the first gear rotates, and then the second gear rotates through the gear transmission, which in turn drives the turntable to rotate, and finally the detection element rotates.

[0031] The detection element is used for detecting the moisture content of rice and can be a moisture detection electrode. The moisture content of rice is detected due to the different conductivity of different water.

[0032] Instructions for use: Add the rice to be tested into the testing chamber from the feeding port, then close the feeding port and ensure that the box door is tightly closed; the rice put into the testing chamber will cover the bottom of the testing piece, and the testing piece will be powered on to start testing to obtain the moisture test result of that point; then start the rotating device, and the gear will rotate to drive the turntable to rotate, so that the testing piece will move to the next testing point for moisture testing; after the test of that point is completed, repeat the above operation until all tests are completed; during use, the turntable can be rotated to a certain angle, and then the rotating device enters the standby state. After the test is completed, turn the device again to start again; after all tests are completed, open the project, take out the rice in the testing chamber, and then carry out the moisture test of the next batch of rice.

[0033] Example 2

[0034] like Figure 1-Figure 3 As shown, the rotating assembly 2 also includes: a guide rod 26, with both ends connected to the box body 1 and the turntable 25 respectively; a slide groove 15 is provided at the position of the guide rod 26 relative to the top of the box body 1, so that the guide rod 26 can rotate along the slide groove 15.

[0035] like Figure 1 、 Figure 3As shown, the detection assembly 3 further includes: a lifting device 32, which is arranged at the bottom of the turntable 25; and a detection member 31 is provided at the bottom of the lifting rod of the lifting device 32.

[0036] like Figure 3 As shown, the detection assembly 3 also includes: a cleaning sleeve 33, which is connected to the turntable 25 through a connecting rod 34; a cleaning chamber 35, which is provided in the cleaning sleeve 33 and allows the detection member 31 to move up and down along the length of the cleaning chamber 35 along the inner side of the cleaning sleeve 33.

[0037] When the rotating device is running, the turntable will be driven to rotate. In order to make the turntable rotate more stably, a guide rod is provided, and a slide groove is provided at the corresponding position on the inner side of the top of the box body. The slide groove is a ring structure. When the rotating device is running, the turntable rotates, and the guide rod will rotate along the slide groove. Multiple guide rods can be provided to ensure that the turntable runs smoothly.

[0038] The lifting device can be made of a cylinder, an electric push rod, etc. When in operation, the lifting rod of the lifting device moves accordingly, thereby driving the detection part to move up and down accordingly, so as to detect the moisture content of rice at different depths.

[0039] During large-scale production, rice needs to be frequently tested for moisture. After a certain period of use, the fine powder trapped in the rice will gradually be adsorbed and accumulated on the outer surface of the detection part, which will affect the accuracy of the test results. Therefore, a cleaning sleeve is provided. When the detection part moves up and down, it will extend into or out of the cleaning cavity of the cleaning sleeve, and the detection part is cleaned by the contact between the cleaning sleeve and the detection part.

[0040] During use, the lifting device operates, driving the lifting rod to move up and down, so that the detection element is located at different positions in the rice, thereby detecting the moisture content of the rice at different depths; the rotating device is started to rotate the turntable, thereby driving the detection element to move to different points for moisture detection; in this way, the rotating device is used in combination with the lifting device to realize moisture detection at different horizontal positions and different depths.

[0046] A valve is provided on the discharge port. After the moisture test is completed, the valve of the discharge port can be opened to facilitate the discharge of rice and then test the next batch of rice. The vertical projection of the discharge port is not on the support plate, which can avoid being restricted by the position of the support plate when taking out the tested rice, resulting in inconvenience in operation.

[0047] When the vibration device is in operation, it can vibrate the rice in the detection bin, making the rice flat and easy to detect; moreover, after the detection is completed, the vibration device can be used to achieve rapid discharge; the vibration device can use a vibration motor.

[0048] The controller is connected to the rotating device, lifting device, and vibration device, and the start-up operation of the above components can be controlled through the controller to improve the convenience of operation; the controller can be provided with a display screen for displaying the test results; connected to the detection part, the data detected by the detection part can be obtained and displayed on the controller, which is convenient for checking the test results.
