Description

Technical Field

[0002] Grains refer to the seeds of grasses and some legumes, such as rice, wheat, corn, soybeans, peas, etc. After the grains are processed, they are stored in the granaries within the grain stations.

[0003] Chinese patent application number CN202321347741.8 discloses a simple device for detecting the moisture content of bagged grains, which belongs to the technical field of detection equipment. It includes a box body and a discharge port, and the discharge port is arranged on the box body. It also includes a humidity detection device, which is snapped on the discharge port; it also includes a sampling rod, one end of the sampling rod is arranged in the box body, and a sampling port is arranged on the other end of the sampling rod, and the sampling port extends to the other end of the sampling rod; the end of the sampling port extending into the sampling rod is connected to the discharge port; the end of the sampling port extending into the sampling rod is connected to the discharge port, and the sampling rod is inserted into the bagged grains.

[0004] The above technical solution takes out the grains through the sampling port, and then enters the box through the sampling port. The grains are selected by the sampling port and reach the humidity detection device through the discharge port connected to the box to obtain the humidity data of the grains. The grains in the granary need to be regularly tested for humidity to prevent the grains from fermenting due to excessive humidity. The granary stores a lot of grains, and the depth of the grains inside the granary is deep. When the above-mentioned grain humidity detection equipment inspects the grains, it extends the sampling rod and inserts it into the grains in the granary to sample the grains. The grains are then flowed into the detection chamber for humidity detection, and the detected grains are then removed. The grain detection device cannot perform layered detection on the grains in the deeper granary, and multiple sampling and detection are required for detecting grains at different depths. The steps in the grain detection process are cumbersome, time-consuming and labor-intensive, which affects the efficiency of grain humidity detection. Summary of the Invention

When the sampling cavity corresponds to the sampling slot, the grain enters the sampling cavity along the sampling slot. When the grain sampling is completed, the knob is continued to be turned, and the rotating shaft rotates with the fixed ring. The multiple partitions continue to rotate.

At this time, the sampling shell is fixed on the surface of the fixed block, and the dial plate moves upward inside the sliding groove, bringing the lower pressure block upward, and then the telescopic end of the second multi-stage telescopic rod is inserted into the fixed ring through the upper through groove. When the through groove corresponds to the notch position, the lower pressure block is reset under the action of the third spring, and the lower pressure block moves downward, bringing the ramp rail downward to squeeze the guide rod. The guide rod passes through the notch and is locked in the through groove. At this time, the telescopic end of the second multi-stage telescopic rod is locked with the fixed ring, thereby realizing the separation of the sampling shell and the cone head from the telescopic device, which is convenient for the storage of the humidity detector.

[0023] 3) When the grain moisture comprehensive monitoring and post-evaluation service device is in use, when the cone head finishes leaking the grain in the granary, the baffle is manually flipped over. At this time, the baffle is separated from the detection slot, and the grain inside the detection slot after the humidity test is completed falls into the granary, and the grain inside the detection slot is discharged, which is convenient for the humidity detector to test the moisture of the grain next time.

One end of the fixed column 15 is fixedly connected to the bottom surface of the rotating shaft 5, and the other end of the fixed column 15 is fixedly connected to the cone head 11. The middle of the surface is fixedly connected, and a baffle 16 is provided on the outside of any detection groove 12. The baffle 16 prevents the grain inside the detection groove 12 from leaking out, and the bottom of the baffle 16 is provided with a chamfer. When the cone head 11 moves downward, the force of the grain on the baffle 16 is reduced. The first multi-stage telescopic rod 2 is extended by the controller 43, and the sampling shell 3 moves downward with the cone head 11 inserted into the grain in the granary. The second multi-stage telescopic rod 24 is extended following the sampling shell 3. Since the sampling groove 4 is closed by the arc plate 7, the grain cannot enter the sampling shell 3. When the sampling shell 3 drops to the position where the grain needs to be detected, the knob 41 is manually turned, and the second multi-stage telescopic rod 24 rotates with the fixed ring 25, thereby causing the rotating shaft 5 to rotate and the multiple partitions 6 to rotate.

When the groove 4 corresponds, the grain enters the sampling cavity along the sampling groove 4. When the grain sampling is completed, continue to turn the knob 41. At this time, the rotating shaft 5 rotates with multiple partitions 6 to continue to rotate. When the arc plate 7 rotates to correspond to the sampling groove 4, the sampling groove 4 is closed again. Then the grain inside the sampling cavity corresponds to the fan-shaped groove 8. At this time, the grain inside the sampling cavity falls into the detection groove 12 along the fan-shaped groove 8 and the discharge groove 10. Then the detector 13 monitors the humidity of the grain inside the detection groove 12. Compared with traditional grain humidity detection equipment, the humidity detector 1 can perform layered detection on the grain at the top, middle and bottom positions, and adopts sampling detection, so that the humidity detector 1 can detect the grain humidity more accurately.The layered detection process is completed at one time, which improves the efficiency of the moisture detector 1 in detecting grain moisture.

A fixing ring 25 is fixedly installed on the top surface of the rotating shaft 5, and a through-type through groove 26 is provided on the surface of the fixing ring 25. The through groove 26 has the same number and corresponding position as the notches 30, and one end of the guide rod 28 passes through the notch 30 and is engaged with the through groove 26.

[0041] The inner wall of the movable groove 34 is slidably connected with a slide rod 33 , and a lower pressing block 31 is fixedly installed on the bottom surface of the slide rod 33 . The surface of the lower pressing block 31 is provided with a ramp rail 32 , and the other end of the guide rod 28 contacts the surface of the ramp rail 32 .

The third spring 35 is used for the movement reset of the lower pressing block 31 .

[0043] The end surface of the second multi-stage telescopic rod 24 is provided with a sliding groove 38 connected to the movable groove 34. The interior of the sliding groove 38 is slidably connected to a dial plate 39 that matches it. One end of the dial plate 39 is fixedly connected to the surface of the lower pressing block 31.

A sliding frame 37 that matches the slide plate 36 is fixedly installed on the inner wall of the second multi-stage telescopic rod 24.

[0044] A frame plate 40 is fixedly mounted on the top surface of the humidity detector 1, the top surface of the second multi-stage telescopic rod 24 is rotatably connected to the frame plate 40, a knob 41 is fixedly mounted on the top surface of the second multi-stage telescopic rod 24, and a handle 42 is fixedly mounted on the surface of the frame plate 40. The setting of the handle 42 makes it convenient for personnel to control the direction of the humidity detector 1.

[0045] A controller 43 is fixedly mounted on the side surface of the rack 40. The controller 43 is a conventional programmable control device in the prior art. The controller 43 is electrically connected to the first multi-stage telescopic rod 2 via a wire. A plurality of displays 44 are fixedly mounted on the surface of the controller 43.

The humidity detection system is a prior art and can be implemented by those skilled in the art. It will not be described in detail here. The display 44 is electrically connected to the detector 13. The display 44 is a conventional display 44 in the prior art. The display 44 is used to display the humidity of the grain detected by the detector 13. A spring shaft 45 is provided between the two side surfaces of the baffle 16 and the detection slot 12. The spring shaft 45 is a conventional spring shaft 45 in the prior art. The baffle 16 is rotatably connected to the detection slot 12 through the spring shaft 45. When the cone head 11 completes leaking the grain in the granary, the baffle 16 is manually flipped over. At this time, the baffle 16 is separated from the detection slot 12. After the humidity detection inside the detection slot 12 is completed, the grain falls into the granary, and the grain inside the detection slot 12 is discharged, which facilitates the humidity detector 1 to detect the humidity of the grain next time.

[0046] The use steps of the present invention are as follows: When the present grain moisture comprehensive monitoring and post-evaluation service device is in use, the block 20 is first pressed manually. At this time, the block 20 slides inside the slide groove 19 and stretches the first spring 21. Then the block 20 is inserted into the slot 18. Under the action of the first spring 21, the block 20 is reset and engaged with the slot 18. At this time, the sampling shell 3 is fixed on the surface of the fixed block 17. Then the dial plate 39 is manually toggled. At this time, the dial plate 39 moves upward inside the sliding groove 38, and moves the lower pressing block 31 upward to compress the third spring 35. Then, the telescopic end of the second multi-stage telescopic rod 24 is inserted into the fixed ring 25 through the upper through groove 23. When the through groove 26 corresponds to the position of the notch 30, the lower pressing block 31 is reset under the action of the third spring 35, and the lower pressing block 31 moves downward. The inclined rail 32 is driven to move downward to squeeze the guide rod 28, and the guide rod 28 passes through the notch 30 and is stuck in the through groove 26 to be locked. At this time, the telescopic end of the second multi-stage telescopic rod 24 is locked with the fixed ring 25, and then the dial plate 39 is locked by the lock buckle in the prior art (the lock buckle is not marked in the figure, and those skilled in the art can install the lock buckle to lock the dial plate 39). In the initial state, the sampling slot 4 is closed by the arc plate 7. Hold the handle 42 with both hands, and then vertically place the humidity detector 1 to the grain to be tested. At this time, operate the controller 43, and the controller 43 controls the first multi-stage telescopic rod 2 to extend. At this time, the sampling shell 3 moves downward with the cone head 11 inserted into the grain in the granary. The second multi-stage telescopic rod 24 extends along with the sampling shell 3. Since the sampling slot 4 is closed by the arc plate 7 Closed, grain cannot enter the sampling shell 3. When the sampling shell 3 drops to the position where the upper grain needs to be detected, stop operating the controller 43, and then manually turn the knob 41. At this time, the knob 41 rotates with the second multi-stage telescopic rod 24, and the second multi-stage telescopic rod 24 rotates with the fixing ring 25, so that the rotating shaft 5 rotates with multiple partitions 6. When the sampling cavity corresponds to the sampling slot 4, the grain enters the sampling cavity along the sampling slot 4. After the grain sampling is completed, continue to turn the knob 41. At this time, the rotating shaft 5 rotates with multiple partitions 6. When the arc plate 7 rotates to correspond to the sampling slot 4, the sampling slot 4 is closed again, and then the grain inside the sampling cavity corresponds to the fan-shaped slot 8. At this time, the grain inside the sampling cavity follows The fan-shaped groove 8 and the discharge groove 10 fall into the detection groove 12, and then the detector 13 monitors the humidity of the grains inside the detection groove 12. The detection data is transmitted to the controller 43 in the form of an electrical signal. The controller 43 processes the signal and transmits the signal to the display 44. The display 44 displays the humidity of the grains at the upper position. After the detection is completed, the first multi-stage telescopic rod 2 continues to extend. At this time, the sampling shell 3 moves downward with the cone head 11 to continue to be inserted into the grain in the granary. The second multi-stage telescopic rod 24 continues to extend following the sampling shell 3. Since the sampling groove 4 is closed by the arc plate 7, the grain cannot enter the sampling shell 3. When the sampling shell 3 drops to the position where the middle grain needs to be detected, the operation steps are the same as the steps for the upper grain detection, and will not be repeated.It should be noted that the direction of rotation of the knob 41 is unidirectional. After the grain detection at the upper, middle and bottom positions inside the granary is completed, the first multi-stage telescopic rod 2 retracts and moves the sampling shell 3 and the cone head 11 upward. When the cone head 11 completes leaking the grain in the granary, the baffle 16 is manually flipped over. At this time, the baffle 16 is separated from the detection groove 12. The grain after the humidity detection inside the detection groove 12 is completed falls into the granary, and the sampling shell 3 is separated from the fixed block 17. Then, the telescopic end of the second multi-stage telescopic rod 24 is separated from the fixed ring 25. After the telescopic device and the sampling device are separated, they are stored separately. This scheme controls the first multi-stage telescopic rod 2 to extend through the controller 43, and the sampling shell 3 moves downward with the cone head 11 inserted into the grain in the granary. The multi-stage telescopic rod 24 extends out with the sampling shell 3. Since the sampling slot 4 is closed by the arc plate 7, the grain cannot enter the sampling shell 3. When the sampling shell 3 drops to the position where the grain needs to be detected, the knob 41 is manually turned, and the second multi-stage telescopic rod 24 rotates with the fixing ring 25, so that the rotating shaft 5 rotates with multiple partitions 6. When the sampling cavity corresponds to the sampling slot 4, the grain enters the sampling cavity along the sampling slot 4. When the grain sampling is completed, the knob 41 is continued to be turned. At this time, the rotating shaft 5 rotates with multiple partitions 6 and continues to rotate. When the arc plate 7 rotates to correspond to the sampling slot 4, the sampling slot 4 is closed again, and then the grain inside the sampling cavity corresponds to the fan-shaped slot 8. At this time, the grain inside the sampling cavity falls into the sampling cavity along the fan-shaped slot 8 and the discharge chute 10. The detector 13 monitors the humidity of the grains in the detection slot 12. Compared with traditional grain humidity detection equipment, the humidity detector 1 can perform layered detection on the grains at the upper, middle and bottom positions, and adopts a sampling method for detection, so that the humidity detector 1 can detect the data of the grain humidity more accurately, and the layered detection process is completed at one time, which improves the efficiency of the humidity detector 1 in detecting the humidity of the grains; by manually pressing the card block 20, the card block 20 slides inside the slide slot 19, and then the card block 20 is inserted into the card slot 18. The card block 20 is reset under the action of the first spring 21 and is engaged with the card slot 18. At this time, the sampling shell 3 is fixed on the surface of the fixed block 17, and the dial plate 39 moves upward inside the sliding slot 38 When the pressing block 31 moves upward, the telescopic end of the second multi-stage telescopic rod 24 is inserted into the fixing ring 25 through the upper slot 23. When the through slot 26 corresponds to the position of the notch 30, the pressing block 31 is reset under the action of the third spring 35, and the pressing block 31 moves downward. The ramp rail 32 moves downward to squeeze the guide rod 28, and the guide rod 28 passes through the notch 30 and is stuck in the through slot 26 to be locked. At this time, the telescopic end of the second multi-stage telescopic rod 24 is locked with the fixing ring 25, realizing the separation of the sampling shell 3 and the cone head 11 from the telescopic device, making it convenient for the storage of the humidity detector 1; when the cone head 11 completes the leakage of the grain in the granary, the baffle 16 is manually flipped over. At this time, the baffle 16 is separated from the detection slot 12, and the grain after the humidity detection inside the detection slot 12 is completed falls into the granary.The grains in the detection tank 12 are discharged to facilitate the humidity detector 1 to detect the humidity of the grains next time.
