Description

Technical Field

[0001] This utility model relates to the technical field of rice moisture content testing equipment, specifically a handheld rice moisture content tester. Background Technology

[0002] Regularly using a handheld moisture meter to check the moisture content of stored rice can help detect changes in moisture levels in a timely manner, prevent the rice from becoming moldy and spoiled, and ensure the quality of the rice.

[0003] The existing handheld rice moisture content meter connects the data cable at the bottom of the probe to the plug at the top of the meter. The probe is inserted into the inside of the stored rice. The change in the moisture content of the rice will cause a change in its dielectric constant, which in turn causes a change in the capacitance value to measure the moisture content of the rice. After use, the data cable is unplugged from the plug.

[0004] Existing handheld rice moisture content testers are prone to data cable bending, twisting, and tangling during daily use and carrying. Prolonged excessive bending and twisting can cause the internal wires of the data cable to break or the insulation layer to be damaged, leading to short circuits, open circuits, and other problems, thus increasing the probability of damage. Therefore, we propose a handheld rice moisture content tester. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a handheld rice moisture content detector. The neatly stored data cable can ensure the smooth movement of the detector, reduce the risk of damage to the instrument due to accidental snagging, and avoid the data cable tangling and excessive bending caused by manual winding, thereby extending the service life of the data cable. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a handheld rice moisture content detector, including a measuring instrument, an insertion port at the top of the measuring instrument, a handle on the outside of the measuring instrument, a probe at the top of the handle, the bottom of each of the two probes being fixedly connected to a contact plate, a contact head at the front end of the contact plate, and a winding mechanism.

[0007] The take-up mechanism includes a rotating shaft, a take-up roller, and a wire groove. The rotating shaft is rotatably connected between the front and rear inner walls of the handle. The take-up roller is fixedly sleeved on the outside of the rotating shaft. The take-up roller has a wire groove on its outside, and a data cable is placed inside the wire groove.

The bottom end of the data cable is inserted into the inside of the socket, and the top end of the data cable is fixedly connected to the rear side of the collector ring. The neatly stored data cable can ensure the smooth movement of the detector, reduce the risk of instrument damage due to accidental snagging, and avoid data cable knots and excessive bending caused by manual winding, thereby extending the service life of the data cable.

[0008] Furthermore, the winding mechanism also includes a slide bar, a slider, and a reciprocating screw. A slider is slidably connected to the outside of the slide bar between the front and rear inner walls of the handle. A through hole is opened in the middle of the slider. The outside of the data cable is slidably connected to the inner wall of the through hole. A reciprocating screw is rotatably connected between the front and rear inner walls of the handle. The left end of the slider is threadedly connected to the outside of the reciprocating screw to achieve orderly winding of the data cable.

[0009] Furthermore, the take-up mechanism also includes sprockets and chains. Sprockets are fixedly fitted on the outer rear end of the rotating shaft and the outer rear end of the reciprocating screw. The two sprockets are connected by chain drive to realize the synchronous operation of take-up and lay-up of the wire.

[0010] Furthermore, the winding mechanism also includes a dial wheel, and the dial wheel is fixedly connected to one end of the shaft extending from the rear side of the handle. A locking bolt is threaded onto the edge of the dial wheel for easy driving.

[0011] Furthermore, a rubber pad is provided on the inner wall of the through hole to reduce friction damage to the data cable.

[0012] Furthermore, anti-slip grooves are provided on the left and right sides of the handle, and the inner walls of the anti-slip grooves are provided with evenly distributed anti-slip textures to prevent them from falling off.

[0013] Furthermore, the measuring instrument has a battery mounting hole on its rear side, and a sliding cover is slidably connected between the top of the left and right inner walls of the battery mounting hole to facilitate battery installation.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This handheld rice moisture content detector has the following advantages:

[0015] Rotating the dial causes the shaft to drive the take-up roller, winding the data cable into the inside of the cable groove. Through chain transmission, the reciprocating screw drives the slider, which, supported and guided by the slide rod, moves the data cable back and forth, achieving orderly winding of the data cable into the inside of the cable groove. This protects the data cable from external environmental interference. During the movement of the detector, the data cable will not be easily hooked or tethered by surrounding objects. The data cable will be orderly wound into the inside of the cable groove, and the neatly wound data cable will not take up extra space, making it convenient for the storage and carrying of the instrument.

Anti-slip grooves 8 are respectively provided on the left and right sides of the handle 3, and the inner walls of the anti-slip grooves 8 are provided with evenly distributed anti-slip textures. A battery mounting hole is provided on the rear side of the measuring instrument 1, and a sliding cover 7 is slidably connected between the top of the left and right inner walls of the battery mounting hole. When detecting the moisture content of rice... Slide the sliding cover 7 at the rear of the measuring instrument 1 to install the battery in the battery mounting hole, then slide the cover 7 to close it. Insert the data cable 5 into the socket 2, and turn the locking bolt to separate the locking bolt from the rear side of the handle 3. Hold the handle 3 and insert the probe 4 into the rice. When the probe 4 is inserted into the rice, a conductive path is formed between the probe 4 and the rice. The moisture in the rice will increase the conductivity of the rice. The conductivity of the rice is positively correlated with its moisture content. The higher the moisture content, the greater the conductivity. The measured data is then transmitted to the measuring instrument 1 through the data cable 5 via the probe 4. The measuring instrument 1 will display the data on the front display screen.

[0023] The take-up mechanism 6 includes a rotating shaft 61, a take-up roller 62, and a wire groove 63. The rotating shaft 61 is rotatably connected between the front and rear inner walls of the handle 3. The take-up roller 62 is fixedly sleeved on the outside of the rotating shaft 61. The take-up roller 62 has a wire groove 63 on its outside, and a data cable 5 is placed inside the wire groove 63. A collector ring 10 is provided on the outside of the front end of the rotating shaft 61. The bottom end of the contact head 11 is slidably connected to the outside of the collector ring 10. The bottom end of the data cable 5 is inserted into the inside of the socket 2, and the top end of the data cable 5 is fixedly connected to the rear side of the collector ring 10. The cable winding mechanism 6 also includes a slide bar 64, a slider 65, and a reciprocating screw 66. A slider 65 is slidably connected to the outside of the slide bar 64 between the front and rear inner walls of the handle 3. A through hole is provided in the middle of the slider 65, and the outside of the data cable 5 is slidably connected to the inner wall of the through hole. A reciprocating screw 66 is rotatably connected between the front and rear inner walls of the handle 3. The left end of the slider 65 is threadedly connected to the outside of the reciprocating screw 66. The cable winding mechanism 6 also includes a sprocket 67 and a chain 68. The outer rear ends of the rotating shaft 61 and the outer rear ends of the reciprocating screw 66 are both fixed. The fixed sleeve is equipped with sprockets 67, and the two sprockets 67 are connected by a chain 68. The take-up mechanism 6 also includes a dial wheel 69. The dial wheel 69 is fixedly connected to one end of the rotating shaft 61 extending from the rear side of the handle 3. A locking bolt is threaded onto the edge of the dial wheel 69. A rubber pad 9 is provided on the inner wall of the hole. After the rice moisture measurement is completed, the data cable 5 is pulled out from the inside of the plug 2. By rotating the dial wheel 69, the rotating shaft 61 is driven to rotate, causing the take-up roller 62 to rotate and wind the data cable 5 into the inside of the cable groove 63. As shaft 61 rotates, it drives the externally sleeved sprocket 67 to start rotating. Through the transmission of chain 68, the sprocket 67 fixedly sleeved at the rear end of reciprocating screw 67 starts to rotate. While reciprocating screw 67 rotates, the threaded slider 65 slides back and forth under the support and guidance of slider 64. Then, through the through hole in the middle of slider 64, it drives the data cable 5 to move back and forth while winding, so that the data cable 5 is wound orderly into the inside of the cable groove 63. After winding is completed, the locking bolt is turned to make it press against the rear wall of handle 3.

[0024] The working principle of the handheld rice moisture content detector provided by this utility model is as follows: When detecting the moisture content of rice, slide open the sliding cover 7 at the rear of the measuring instrument 1, install the battery in the battery mounting hole, then slide the sliding cover 7 closed, insert the data cable 5 into the socket 2, and tighten the locking bolt to separate the locking bolt from the rear side of the handle 3. Holding the handle 3, insert the probe 4 into the rice (when the probe 4 is inserted into the rice, a conductive path is formed between the probe 4 and the rice; the moisture in the rice increases the conductivity of the rice, and the conductivity of the rice is positively correlated with its moisture content; the higher the moisture content, the greater the conductivity). The measured data is transmitted to the measuring instrument 1 through the data cable 5 via the probe 4, and the measuring instrument 1 displays the data on the front display screen. After measuring the moisture content of the rice, pull the data cable 5 out of the socket 2. By rotating the dial 69, the rotating shaft 61 will start to rotate, causing the take-up roller 62 to rotate and wind the data cable 5 into the wire groove 63. At the same time as the rotating shaft 61 rotates, the externally mounted sprocket 67 will start to rotate. Through the transmission of the chain 68, the sprocket 67 fixedly mounted at the rear end of the reciprocating screw 67 will start to rotate. At the same time as the reciprocating screw 67 rotates, the threaded slider 65 will slide back and forth under the support and guidance of the slide rod 64. Then, through the through hole in the middle of the slider 64, the data cable 5 will move back and forth while being taken in, so that the data cable 5 is wound into the wire groove 63 in an orderly manner. After winding, turn the locking bolt to tighten it against the rear wall of the handle 3.
