[0001] The present application relates to the field of moisture meters, and particularly to a feeding structure of an online grain moisture meter. Background Art
[0002] A grain moisture meter is a device used to measure the moisture content in grains, and is widely used in agriculture, grain storage and processing, etc. It can provide accurate moisture content data in a short time, and adopts advanced sensors and algorithms to ensure reliable measurement results. Some models are easy to carry and suitable for on-site use. They can measure various grains such as wheat, corn, rice, etc. They are easy to operate and usually equipped with a digital display screen.
[0003] At present, the working environment of grain moisture meters on the market is relatively harsh. Grains mixed with impurities directly impact on the detection wheels, causing serious wear on the surfaces of the detection wheels, resulting in a continuous decline in detection accuracy. At the same time, grains all fall between the detection wheels at the same time, and there are more grains being rolled at the same time, making it impossible to accurately measure the moisture content of the grains.
[0004] In view of this, we propose a feeding structure of an online grain moisture meter to solve the above problems. Summary of the Invention

[0028] Embodiment 1:
[0029] The present invention provides a feeding structure for an on-line grain moisture meter. Please refer to Figures 1-4 , which includes a control mechanism 1. The control mechanism 1 includes a housing 11. An installation plate 12 is fixedly installed inside the housing 11. A detection component 14 is installed on the installation plate 12. A protective housing 2 is provided on the front wall of the housing 11. A driving component 13 is installed on the installation plate 12. A bracket component 3 is fixedly installed on a side wall of the housing 11 close to the protective housing 2. The bracket component 3 includes an outer installation frame 31 fixedly installed on the outer wall of the housing 11. The side wall of the outer installation frame 31 away from the housing 11 is arranged obliquely from top to bottom and from inside to outside. A feeding mechanism 4 is fixedly provided on the side wall of the outer installation frame 31 away from the housing 11. The feeding mechanism 4 includes an enclosing material component 41 and a rotating component 42 rotatably connected inside it. The driving component 13 drives the rotating component 42 to rotate.
[0030] Specifically, the inclined feeding mechanism 4 is used to receive a part of the falling grains. Cooperating with the driving component 13 to drive the rotating component 42 to rotate, the grains inside the enclosing material component 41 can be conveyed upward and crushed by the detection component 14 to detect their moisture content, realizing the detection of grains one by one, effectively improving the detection accuracy, and at the same time avoiding large-particle impurities from entering and damaging the detection component 14.
[0031] The driving component 13 includes a servo motor. The output end of the servo motor is fixedly connected with a driving shaft 131. An inclined gear 133 is arranged at one end of the driving shaft 131 away from the installation plate 12. A gear 134 is fixedly installed on the outer wall of the driving shaft 131. A bearing sleeve 132 is arranged on the outer wall of the driving shaft 131.
[0032] Specifically, a PLC circuit board is arranged behind the installation plate 12. The servo motor is electrically connected to the circuit board. The bearing sleeve 132 is installed on the housing 11, which can ensure that the driving shaft 131 can rotate freely after passing through the housing 11.
[0033] Embodiment 2:
[0034] The present invention provides a feeding structure for an on-line grain moisture meter. Please refer to Figures 4-7, the detection assembly 14 includes a pair of rotating shafts 141 rotatably connected to the mounting plate 12. Detection wheels 143 are provided at one end of the rotating shafts 141 away from the mounting plate 12. Gear two 142 is provided on the outer wall of each rotating shaft 141. The two gear two 142 are meshed with each other, and the gear two 142 is meshed with the gear one 134.
[0035] Specifically, the rotation of the gear one 134 on the drive shaft 131 drives the rotation of the gear two 142, and then drives the rotation of a pair of rotating shafts 141. The detection wheels 143 can rotate inward synchronously to roll the grains. The meshing connection between the three gears enables one servo motor to drive multiple mechanisms to work, reducing the production cost of the device and improving its practicability.
[0036] The material surrounding assembly 41 includes a bottom plate 411. A communication groove 412 is opened at the upper end of the bottom plate 411. A fixed ring 413 is fixedly connected to the side wall of the bottom plate 411 away from the mounting plate 12. A falling groove 414 corresponding to the position of the communication groove 412 is opened at the bottom of the fixed ring 413. A notch groove 415 is opened on the side wall of the fixed ring 413.
[0037] The rotating assembly 42 includes a connecting shaft 421 passing through the bottom plate 411 and the communication groove 412. A helical gear two 422 is provided at one end of the connecting shaft 421 close to the mounting plate 12. The helical gear two 422 is in frictional contact connection with the helical gear one 133. The other end of the connecting shaft 421 is fixedly connected with a rotating disc 424. Reserved grooves 425 are symmetrically opened at the upper and lower ends of the rotating disc 424. A pushing flap 426 is provided at the edge of the side wall of the rotating disc 424 away from the mounting plate 12. A bearing sleeve two 423 is provided on the outer wall of the connecting shaft 421.
[0038] Specifically, the pushing flap 426 can push away the excess grains accumulated below, preventing the grains conveyed up from always being the same batch, which may cause deviation in detection.
[0039] An inner mounting plate 32 is provided inside the outer mounting frame 31. A material guiding box 33 is fixedly installed on one side wall of the inner mounting plate 32 away from the control mechanism 1. The upper opening of the material guiding box 33 corresponds to the communication groove 412, and the lower opening of the material guiding box 33 corresponds to the connection part of the two detection wheels 143.
[0040] Specifically, please refer to Figure 9, when grains fall into the material surrounding component 41, the reserved slot 425 of the rotating disk 424 can accommodate one grain of grain. The first helical gear 133 of the driving component 13 drives the second helical gear 422 to rotate, so that the connecting shaft 421 drives the rotating disk 424 to rotate. As a result, the grains inside the lower reserved slot 425 can be conveyed to the upper part, and fall into the material guiding box 33 through the communication slot 412 and the falling slot 414. The grains slide downward along the material guiding box 33 and are crushed by the detection wheel 143 to detect their moisture content, realizing the detection of grains one by one, effectively improving the detection accuracy, and at the same time avoiding large-particle impurities from entering and damaging the detection component 14.
[0041] Further, according to the types and particle sizes of specific grains, the granulation detection of grains can be realized by replacing the rotating disk 424 with different sizes of reserved slots 425.
[0042] Please refer to Figure 8 , the protective housing 2 includes a feeding area 21 provided on a side wall away from the control mechanism 1. A straight plate 22 is arranged inside the feeding area 21. A feeding slot 23 is opened on the straight plate 22. An inner folding plate 24 corresponding to the position of the feeding slot 23 is arranged on the straight plate 22. A discharge slot 25 is opened at the lower end of the protective housing 2. Half of the fixed ring 413 is exposed outside the feeding slot 23.
[0043] Specifically, the feeding area 21 is embedded inward for a certain distance, effectively preventing the fixed ring 413 from being directly exposed outside. The embedded structure of the feeding area 21 can be used for effective shielding to prevent a large amount of grains from directly impacting inside the fixed ring 413, resulting in the inability to realize granulation detection. The inner folding plate 24 is to make room for the notch slot 415 so that excess grains can be pushed out of the notch slot 415 by the pushing flap 426..
[0044] The above is only the best implementation mode adopted by the present application in combination with the current actual requirements, but the protection scope of the present application is not limited thereto.
