Description

Technical Field

[0001] This utility model belongs to the technical field of raw grain quality testing equipment, and in particular relates to a raw grain testing and screening equipment. Background Technology

[0002] As is well known, in the grain storage process, pricing and grading of raw grains are required based on their quality information. Currently, the raw grains are tested according to national grain testing standards, which involve sampling, sorting, and sieving. All these processes are performed manually.

[0003] Currently in the industry, after raw grains are combined and sampled, different vibrating sieves are generally used to sieve the samples to obtain the weight of the clean sample and impurities, thereby calculating the impurity percentage. However, because the clean sample after sieving contains a certain amount of dust and light impurities, such as wheat husks, the clean sample will generate not only dust but also wheat husks and other light impurities during the process of flowing to the weighing equipment. If these are not treated, they may affect the subsequent test results of the clean sample. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a raw grain detection and screening device, which solves the above problems.

[0005] To achieve the above objectives, this utility model discloses a grain detection and screening device, comprising:

[0006] A sieving module, comprising a vibrating screen, a clean sample guide pipe, and an impurity guide pipe, wherein the vibrating screen conveys the sieved clean sample and impurities to a weighing module through the clean sample guide pipe and the impurity guide pipe, respectively.

[0007] The weighing module is used to weigh the impurities and the net sample separately.

[0008] And a sample cleaning and dust removal module, which is connected to the sample guide pipe and is used for sample cleaning and dust removal.

[0009] Compared with existing technologies, this application has the following advantages: During use, the vibrating screen is turned on, and the screened clean sample and impurities flow into the weighing module through the clean sample guide pipe and impurity guide pipe, respectively. The weighing module then weighs the clean grain and impurities. A clean sample dust removal module is connected to the clean sample guide pipe. When the clean sample dust removal module operates, it removes dust and lightweight impurities such as wheat husks from the clean sample, thus preventing problems that could affect the clean sample testing results.

[0010] Furthermore, the sample cleaning and dust removal module includes a dust collector, a dust removal pipe, and a baffle. The dust collector is connected to the sample guide pipe through the dust removal pipe. The baffle is disposed inside the sample guide pipe and is located on the side of the dust removal pipe near the air inlet, which is used to separate the sample from the air inlet.

[0011] Furthermore, the baffle is an L-shaped baffle.

[0012] Furthermore, a transparent acrylic plate is provided on the outside of the sample guide tube.

[0013] Furthermore, the weighing module includes a clean sample weighing hopper and an impurity weighing hopper respectively disposed below the clean sample guide pipe and the impurity guide pipe.

[0014] Furthermore, a clean sample storage hopper and an impurity storage hopper are respectively provided below the clean sample weighing hopper and the impurity weighing hopper.

[0015] Furthermore, the clean sample weighing hopper includes a clean sample hopper, a clean sample weighing sensor, and a clean sample opening mechanism, and the impurity weighing hopper includes an impurity hopper, an impurity weighing sensor, and an impurity opening mechanism.

[0016] Furthermore, the sample opening mechanism includes a sample opening cylinder, and the sample hopper includes a sample rotating plate and a sample fixing plate that are hinged to each other, so that when the sample opening cylinder extends, it can push the sample rotating plate to rotate around the sample fixing plate.

[0017] Furthermore, the impurity opening mechanism includes an impurity opening cylinder and a tension spring. The impurity hopper includes an impurity rotating plate and an impurity fixing plate that are hinged to each other. The impurity rotating plate is connected to the tension spring so that when the impurity opening cylinder extends, it can push the impurity rotating plate to rotate around the impurity fixing plate and stretch the tension spring.

[0018] Furthermore, the telescopic end of the impurity opening cylinder is equipped with rollers. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-3 As shown, this utility model discloses a grain detection and screening device, comprising:

[0027] The sieving module includes a vibrating screen 1, a clean sample guide pipe 2, and an impurity guide pipe 3. The vibrating screen 1 transports the sieved clean sample and impurities to the weighing module through the clean sample guide pipe 2 and the impurity guide pipe 3, respectively.

[0028] The weighing module is used to weigh the impurities and the net sample separately.

[0029] And a sample cleaning and dust removal module, which is connected to the sample guide pipe 1 and is used for sample cleaning and dust removal.

[0030] Compared with existing technologies, this application has the following advantages: In use, the vibrating screen 1 is turned on, and the screened clean sample and impurities flow into the weighing module through the clean sample guide pipe 2 and impurity guide pipe 3, respectively. The weighing of the clean grain and impurities is completed on the weighing module. A clean sample dust removal module is connected to the clean sample guide pipe 1. When the clean sample dust removal module operates, it removes dust and lightweight impurities such as wheat husks from the clean sample, thereby avoiding problems that could affect the clean sample testing results.

[0031] Following the above embodiment, more specifically, the sample cleaning and dust removal module includes a dust collector 4, a dust collection pipe 5, and a baffle 6. The dust collector 4 is connected to the sample guide pipe 2 via the dust collection pipe 5. The baffle 6 is disposed inside the sample guide pipe 2 and is located on the side of the dust collection pipe 5 near the air inlet, separating the sample from the air inlet. The dust collector 4 can be a cyclone dust collector. The design of the baffle 6 effectively prevents the clean grain from entering the air inlet, thus preventing the dust collector 4 from sucking away the clean grain.

[0032] Following the above embodiment, more specifically, the baffle 6 is an L-shaped baffle, thereby preventing clean grain from entering the air inlet through the bottom of the baffle 6.

[0033] Following the above embodiment, more specifically, a transparent acrylic plate is provided on the outside of the clean sample guide tube 2, through which the dust removal and impurity removal of the clean sample inside the clean sample guide tube 2 can be observed.

[0034] Following the above embodiment, more specifically, the weighing module includes a clean sample weighing hopper 7 and an impurity weighing hopper 8 respectively disposed below the clean sample guide pipe 2 and the impurity guide pipe 3. The clean sample weighing hopper 7 and the impurity weighing hopper 8 are not in contact with the clean sample guide pipe 2 and the impurity guide pipe 3 to prevent the vibration force from being transmitted to the clean sample weighing hopper 7 and the impurity weighing hopper 8 through the clean sample guide pipe 2 and the impurity guide pipe 3 when the vibrating screen 1 vibrates, thus affecting the accuracy of the clean sample and impurity weighing.

[0035] It should be noted that both the clean sample guide tube 2 and the impurity guide tube 3 have a section made of non-woven fabric for flexible connection. This not only facilitates the connection between components, but also prevents the outlets of the clean sample guide tube 2 and the impurity guide tube 3 from swinging back and forth due to the vibration of the vibrating screen 1, thereby preventing the clean sample guide tube 2 and the impurity guide tube 3 from touching the clean sample weighing hopper 7 and the impurity weighing hopper 8.

[0036] Following the above embodiment, more specifically, a clean sample storage hopper 9 and an impurity storage hopper 10 are respectively provided below the clean sample weighing hopper 7 and the impurity weighing hopper 8. The clean sample and impurities weighed in the clean sample weighing hopper 7 and the impurity weighing hopper 8 can be temporarily stored in the clean sample storage hopper 9 and the impurity storage hopper 10 to facilitate the operation of the next process.

[0037] Following the above embodiment, more specifically, the clean sample weighing hopper 7 includes a clean sample hopper, a clean sample weighing sensor, and a clean sample opening mechanism, while the impurity weighing hopper 8 includes an impurity hopper, an impurity weighing sensor, and an impurity opening mechanism. The clean sample weighing sensor is used to weigh the clean sample in the clean sample hopper, and the impurity weighing sensor is used to weigh the impurities in the impurity hopper. After weighing, the clean sample opening mechanism and the impurity opening mechanism open, allowing the clean sample and impurities to fall into the clean sample temporary storage hopper 9 and the impurity temporary storage hopper 10 for temporary storage.

[0038] Following the above embodiments, more specifically, as Figure 3 As shown, the sample opening mechanism includes a sample opening cylinder 11, and the sample hopper includes a sample rotating plate 12 and a sample fixing plate 13 hinged together. When the sample opening cylinder 11 extends, it can push the sample rotating plate 12 to rotate around the sample fixing plate 13. When the sample opening cylinder 11 extends, it pushes the sample rotating plate 12 to rotate upward around the sample fixing plate 13, thereby creating a gap between the sample rotating plate 12 and the sample fixing plate 13, thus opening the sample opening mechanism and allowing the sample to fall into the sample temporary storage hopper 9 through the gap. When the sample opening cylinder 11 retracts, the sample rotating plate 12 returns to its original position under its own gravity, thus closing the sample opening mechanism.

[0039] Continuing with the above embodiment, more specifically, the impurity opening mechanism includes an impurity opening cylinder 14 and a tension spring. The impurity hopper includes an impurity rotating plate 15 and an impurity fixing plate 16 hinged together. The impurity rotating plate 15 is connected to the tension spring so that when the impurity opening cylinder 14 extends, it can push the impurity rotating plate 15 to rotate around the impurity fixing plate 16 and stretch the tension spring. Specifically, when the impurity opening cylinder 14 extends, it pushes the impurity rotating plate 15 to rotate downward around the impurity fixing plate 16, thereby creating a gap between the impurity rotating plate 15 and the impurity fixing plate 16, thus opening the impurity opening mechanism. Impurities fall into the impurity temporary storage hopper 10 through the gap, and at the same time, the tension spring is stretched due to the rotation of the impurity rotating plate 15. When the impurity opening cylinder 14 retracts, the impurity rotating plate 15 returns to its original position under the tension of the tension spring, thus closing the impurity opening mechanism.

[0040] Following the above embodiment, more specifically, the telescopic end of the impurity opening cylinder 14 is provided with a roller 17. The roller 17 design ensures that the impurity opening cylinder 14 and the impurity rotating plate 15 form a sliding contact, further protecting the impurity rotating plate 15.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
