Description

Technical Field

[0001] This utility model relates to the technical field of grain hoppers, and specifically to a grain feeding device installed on a grain hopper. Background Technology

[0002] Grain dryers, as thermal drying equipment for various types of bulk grains (including rice, wheat, corn, soybeans, and rapeseed), have become an important part of the modernization of grain production due to the rapid development of modern agriculture and the continuous increase in the output of various grain crops.

[0003] In the structural design of traditional grain drying equipment, moisture meters are usually integrated into the bucket elevator to monitor the moisture content of the grain inside the elevator. However, it should be noted that the grain being transported by the elevator has already undergone a period of time before completing the full drying process, leading to inaccuracies in the monitoring data.

[0004] Therefore, the existing improved technology moves the moisture detection device to the inside of the grain hopper structure below the grain discharge section, using the inclined guide surface of the grain hopper to achieve directional collection and detection of grain samples. Compared to the elevator installation scheme, this layout allows the moisture detector to contact the grain that has just completed the drying process, theoretically resulting in better detection results.

[0005] However, the current solution relies on the natural flow characteristics of the inclined surface of the large bucket for grain collection, which exposes technical defects such as incomplete contact of the moisture detector in actual working conditions.

[0006] To address this problem, we provide a grain feeding device installed on the lower grain hopper. Utility Model Content

[0007] To address the problems existing in the prior art, this utility model provides a grain feeding device installed on the lower grain hopper. The feeding device integrates guiding, slowing and discharging functional modules. Through a coordinated guiding mechanism composed of a diversion baffle and a guide vane, the grain sample is directionally guided to the moisture detector, realizing real-time collection of the grain condition after drying.

[0008] To achieve the above objectives, this utility model employs a grain feeding device installed on the lower grain hopper, comprising:

[0009] A feeding mechanism installed on the side wall of the grain hopper includes a grain guide trough for introducing grain, a grain slow-flow channel along the grain guide trough, and a discharge section for discharging grain through the grain slow-flow channel. At least one moisture meter is installed at the monitoring station of the discharge section. When grain enters the grain slow-flow channel axially along the grain guide trough and is discharged through the discharge section, at least one moisture meter detects the moisture content of the grain discharged from the discharge section. The grain guide trough, grain slow-flow channel, and discharge section constitute the feeding hopper. The axial cross-section of the feeding hopper is configured in a linearly tapering shape. This structure integrates guiding, slow-flow, and discharge functions, guiding the grain sample directionally to the moisture meter, enabling real-time online monitoring of the dried grain.

[0010] As a further optimization of the above solution, the material handling mechanism is integrated with a bearing base plate fixed to the main structure of the feeding hopper. Two reinforcing ribs are symmetrically distributed on the surface of the bearing base plate. On the one hand, the reinforcing ribs strengthen the overall strength of the material handling mechanism, and on the other hand, they limit the flow of grain between the two reinforcing ribs.

[0011] As a further optimization of the above solution, the feed hopper is integrated with a flow divider plate parallel to the plane of the supporting substrate. The end of the flow divider plate is fixedly connected to a guide vane plate extending into the inside of the feed hopper. The feed hopper is integrated with a sliding plate connecting the flow divider plate and the guide vane plate. The sliding plate is fixedly connected to the lower edge of the flow divider plate and the side wall of the guide vane plate respectively. There is a flow guiding angle between the plane of the sliding plate plate and the plane of the supporting substrate plate.

[0012] As a further optimization of the above solution, the inlet end of the feed hopper is integrated with an openable and closable feed port, on which a detachable glass insert plate is installed. Operators can perform periodic sample checks by opening and closing the feed port to ensure that the test data is synchronized with the moisture content of mainstream grains. The light transmittance of the observation plate allows for visual monitoring of the inside of the guide channel during equipment operation, enabling real-time identification of material accumulation or abnormal flow conditions. When the feed port is closed, its sealing interface effectively prevents external dust from entering the detection channel, maintaining the cleanliness of the testing environment.

[0026] Please refer to the instruction manual appendix. Figure 1-4 This utility model provides a first embodiment of a grain feeding device installed on a grain hopper. In this embodiment, the grain feeding device includes a feeding mechanism 2 rigidly fixed to the wall of the grain hopper 1. The feeding mechanism 2 consists of a grain guide trough 21, a grain slow flow channel 22, and a discharge section 23, forming a feeding hopper. The grain guide trough 21 adopts an axial feeding design to achieve directional grain conveying, the grain slow flow channel 22 guides the grain flow, and a moisture detector 3 is installed in the discharge section to monitor the process. After the grain that has completed the drying process is axially introduced through the guide section, it flows in the grain slow flow channel 22 and finally passes through the detection area of ​​the discharge section 23. During this process, the moisture detector 3 collects the moisture content data of the grain flowing through it in real time.

[0027] The material handling mechanism 2 employs a support base plate 4 rigidly connected to the main structure of the feeding hopper. Two reinforcing ribs 5 are symmetrically arranged on the surface of the support base plate 4. The two reinforcing ribs 5 are welded to the support base plate 4. These reinforcing ribs 5 enhance the overall strength of the material handling mechanism 2 and also limit the flow of grain between the two reinforcing ribs 5.

[0028] In detail, the feed hopper is provided with a flow divider 6 that is parallel to the plane of the support substrate 4. The end of the flow divider 6 extends into the feed hopper with a preset radius of curvature to form a guide vane 7. A sliding plate 8 is fixed to the lower edge of the flow divider 6 and the side wall of the guide vane 7, respectively. The sliding plate 8 is fixed at a preset angle between the lower edge of the flow divider 6 and the side wall of the guide vane 7, and its mounting plane forms a guide angle with the plane of the support substrate 4.

[0029] Furthermore, the feed hopper inlet is equipped with an openable and closable feed port 9. The main frame of the feed port 9 is fixed with a flange connection structure to a detachable light-transmitting glass plate 91. The glass plate 91 is made of high light transmittance tempered glass.

[0030] During operation, operators conduct periodic manual sample checks by opening and closing the feed inlet 9, and simultaneously calibrate the online detection data and the moisture content parameters of mainstream grains; the light transmittance characteristics of the observation plate support continuous visual monitoring of the flow state inside the guide channel during equipment operation, and identify local accumulation or abnormal flow phenomena of materials in real time; when the feed inlet 9 is closed, it effectively blocks external dust from entering the detection channel and ensures the cleanliness of the detection environment.

[0031] This embodiment provides a grain feeding device installed on a lower grain hopper, and its working process is as follows:

[0032] Grains fall naturally from the inclined surface of the lower grain hopper 1 and are axially introduced into the feed hopper inlet via the guide section of the feeding mechanism 2. During the directional conveying process in the guide section, the grains are laterally constrained by the double rows of reinforcing ribs 5 on the surface of the bearing base plate 4, and enter the grain slow flow channel 22 with a linearly tapered cross section along the central axis. The grains flow within the grain slow flow channel 22 and finally pass through the detection area of ​​the discharge section 23. During this process, the moisture detector 3 collects the moisture content data of the grains flowing through it in real time.

[0033] In summary, the grain feeding device installed on the lower grain hopper of this utility model, through the integrated feeding hopper structure design of guiding, slowing and discharging functions, guides the grain sample to the moisture detector 3, realizing real-time online detection of the grain after drying.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
