DETAILED DESCRIPTION

[0029] The concept, specific structure and technical effects of the present application will be described clearly and completely in combination with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present application.

[0030] A raw grain weight and moisture detection device, as shown in Figure 1 , Figure 2 and Figure 3 , comprises a rack 1, a storage hopper 2, a detection hopper 3, a receiving hopper 4, a weighing sensor 5 and a moisture detector 6.

[0031] The storage hopper 2, the detection hopper 3 and the receiving hopper 4 are sequentially assembled on the rack 1 from top to bottom, and the bottom end of the discharge port of the upper hopper is opposite to the top end of the feeding port of the lower hopper in the adjacent two hoppers, and the bottom end of the storage hopper 2 and the detection hopper 3 is provided with a discharge door.

[0032] The detection hopper 3 is placed on the weighing sensor 5, and the inclined step surface 31 is arranged on the outer wall of the detection hopper 3, and the probe of the moisture detector 6 is inserted into the detection hopper 3 obliquely through the inclined step surface 31.

[0033] In this embodiment, in use, the raw grain material is first stored in the storage hopper 2, and then enters the detection hopper 3 during detection, and the weight and moisture of the raw grain material in the detection hopper 3 are detected by the weighing sensor 5 and the moisture detector 6 respectively, and after detection, the raw grain material enters the receiving hopper 4 for storage.

[0034] For the weighing sensor 5, it detects the total weight of the detection hopper 3 and the raw grain material, and the weight of the raw grain material in the detection hopper 3 is obtained by subtracting the weight of the detection hopper 3 from the total weight.

[0035] For the moisture detector 6, it is a conventional moisture detector, and the probe is arranged at the head. In this embodiment, the probe is fixed into the raw grain material at a more vertical angle, which can achieve ideal moisture detection effect, and at the same time, it avoids being deformed and damaged by the impact of the falling raw grain material, or being hung by impurities and fiber ends brought by the raw grain material (compared with the more horizontal fixing mode), and it also does not need an additional cylinder to drive the moisture detector 6 to insert repeatedly.

[0036] As shown in Figure 1As shown, the rack 1 is also equipped with a scraper 7 for scraping the top of the detection hopper 3, and the scraper 7 is above the top end face of the detection hopper 3. The scraper 7 can be manually driven or electrically driven. The scraper 7 is placed on the top of the detection hopper 3, and the scraper 7 is reciprocally driven to scrape the excess raw grain material on the top of the detection hopper 3, so that the top of the detection hopper 3 is flush, so that the volume of the raw grain material in the detection hopper 3 is consistent with the volume of the detection hopper, so that the subsequent weight of the detected raw grain material is divided by the volume of the detection hopper to obtain the density of the raw grain material.

[0037] As shown in the figure, Figure 1 The rack 1 is also equipped with a residual material chute 8 for guiding the residual material scraped by the scraper 7. The two inclined surfaces of the residual material chute 8 can be welded or integrally formed to cover the underlying components and mechanisms, so that the scraped residual material does not fall on these components and mechanisms, but slides down the inclined surfaces to the left and right, and then directly falls into the bottommost receiving hopper 4. The bottom of the receiving hopper 4 has an opening for the residual material to flow out and be recycled.

[0038] As shown in the figure, Figure 1 The bottom end of the storage hopper 2 is provided with a storage discharge door, and the rack 1 is equipped with a storage discharge door cylinder 9 which is drivingly connected with the storage discharge door. The storage discharge door can adopt a conventional structure in the prior art, such as a plug-in discharge door, which is horizontally inserted into the outlet of the storage hopper 2 to close the outlet of the storage hopper 2, and when it is needed to be opened, the plug-in discharge door is pulled out to open the outlet of the storage hopper 2. The driving mode of the storage discharge door can be manual or electric, and when it is electric, the storage discharge door cylinder 9 is used to reciprocally move the storage discharge door to open or close the outlet of the storage hopper 2.

[0039] As shown in the figure, Figure 1 The bottom end of the detection hopper 3 is provided with a detection discharge door, and the rack 1 is equipped with a detection discharge door cylinder 10 which is drivingly connected with the detection discharge door. The structure and principle of the detection discharge door are similar to those of the above-mentioned storage discharge door, and will not be repeated here.

[0040] As shown in the figure, Figure 2 The rack 1 is equipped with a scraper cylinder 11 which is drivingly connected with the scraper 7, and the scraper cylinder 11 is used to reciprocally drive the scraper 7 to scrape the excess raw grain material on the top of the detection hopper 3, so that the top of the detection hopper 3 is flush.

[0041] As shown in the figure, Figure 4 It also includes a controller, a display and a power supply; the controller is electrically connected with the weighing sensor 5, the moisture detector 6, each cylinder and the display, and the power supply is electrically connected with the weighing sensor 5, the moisture detector 6, the controller, the display and each cylinder.

[0042] In the embodiment, the controller, the display and the power supply can be conventional structures, the controller is used for overall controlling the raw grain weight and moisture detection, the display is used for displaying the raw grain weight and moisture detection result, and the power supply (not shown in the figure) is used for supplying power for various electrical elements.

[0043] In order to better understand the utility model, the working principle of the utility model is described once completely as follows:

[0044] The raw grain material is first stored in the storage hopper 2, and when detection is performed, the raw grain material is excessively discharged from the storage hopper 2 to the intermediate detection hopper 3, the excess raw grain is scraped off by the scraper 7 beyond the upper plane of the detection hopper 3, so that the volume of the raw grain material is consistent with the volume of the detection hopper; then the weight of the raw grain material is obtained by the weighing sensor 5, and the density of the raw grain material is calculated by using the volume of the detection hopper 3; in addition, the moisture detector 6 installed on the wall of the detection hopper 3 and fixedly inserted into the raw grain material simultaneously obtains the moisture content. After detection is completed, the raw grain material is unloaded into the lower receiving hopper 4 and flows out of the equipment.

[0045] The embodiment of the utility model is described above, but the utility model is not limited to the described embodiment, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent or replacements are all included in the range defined by the claims of the utility model.
