Description

Technical Field

[0001] This utility model relates to the field of grain processing machinery technology, specifically a sample sorting device for grain testing. Background Technology

[0002] In the processes of grain acquisition, storage, and processing, obtaining representative small samples through sample division is a crucial prerequisite for subsequent quality testing. To ensure the accuracy and efficiency of sample division, automated or semi-automated sample division devices are widely used. These devices typically include a motor-driven rotary sample division mechanism for mixing and dividing the input grain.

[0003] However, in existing technologies, such motor-driven rotary sampling mechanisms inevitably generate vibrations during operation. This vibration affects the overall stability of the equipment, especially on uneven surfaces, potentially leading to decreased sample uniformity. More importantly, the sample collection bins in existing devices are typically positioned using simple placement or slots. Under continuous vibration, these bins are prone to slight displacement or gaps between themselves and the discharge port. This unstable connection not only causes sample spillage and cross-contamination after sampling but also affects the accuracy and representativeness of the final sampling, thus interfering with subsequent grain testing results.

[0004] Therefore, this utility model proposes a sampling device for grain testing to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a grain testing sampling device, which aims to improve the existing grain testing sampling devices, which suffer from insufficient overall stability due to equipment vibration, and the simple connection between the storage box and the discharge port used to collect samples, which is prone to displacement during vibration and sample spillage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A grain testing sampling device includes: a housing, a sampling mechanism, a discharge bin, a storage bin, a slider, and an elastic locking block.

[0007] The sample separation mechanism includes a rotating disk driven by a motor, on which a conical cylinder is provided.

[0008] Furthermore, the slider is slidably connected to the discharge bin, and the elastic block is located on the storage box. The slider and the elastic block cooperate by the slider sliding and pressing the elastic block to fix the storage box.

[0009] Preferably, the sample separation mechanism further includes a connecting rod, which is connected between the rotating disk and the conical cylinder.

[0010] Preferably, the rotating disk is also provided with a rib that surrounds the conical cylinder.

[0011] Preferably, the rotating disk is also provided with a prism plate.

[0012] Preferably, the device further includes a telescopic rod connected to the housing, and the end of the telescopic rod is provided with an anti-slip pad.

[0013] Preferably, the telescopic rod is connected to the box body via a fixed rod.

[0014] Preferably, the device further includes a baffle plate located above the motor.

[0015] Preferably, the top of the box is provided with a feed inlet, and a feed hopper is connected to the feed inlet.

[0016] Preferably, the storage bin is equipped with a handle.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem that the storage box connection method in existing grain sampling devices is simple and prone to displacement or falling off when the equipment vibrates by setting a slider that is slidably connected in the discharge bin and an elastic locking block set on the storage box and cooperating with the slider. It achieves the effect of quickly and reliably fixing the storage box, ensuring complete collection of samples after sampling and avoiding sample spillage.

[0018] 2. This utility model solves the problem of decreased sample representativeness caused by unstable structure and unreliable sample collection in the prior art by combining the motor-driven rotary sampling mechanism with the storage box locking structure and the overall support structure. It achieves the technical effect of ensuring the continuity of the automated sampling process and the accuracy of sample collection, thereby improving the representativeness of the final sample and the reliability of the test results.

[0021] 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.

[0022] Reference Figures 1-5 A grain sampling device is proposed to solve the problems of insufficient stability due to vibration and loose connection of storage tank in existing grain sampling devices.

[0023] The grain testing sampling device includes a housing 1 and a sampling mechanism located inside the housing 1. The housing 1 serves as the mounting base and supporting shell for the entire device, and the sampling mechanism is used to disperse and sample the input grain.

[0024] The slider 17 has a structure that moves in its vertical direction and is disposed inside the discharge bin 14. Its function is to provide a point of action for fixing the storage bin 15. A corresponding elastic block 18 is provided on the storage bin 15. The elastic block 18 is integrally formed on the side wall of the storage bin 15 and extends toward the slider 17.

[0025] In the assembled state, when the storage bin 15 is pushed under the discharge hopper 14, the slider 17 can slide along its direction of movement, pressing the elastic locking block 18 on the storage bin 15. This cooperative structure of the slider 17 pressing the elastic locking block 18 ensures that the storage bin 15 is firmly locked and fixed under the discharge hopper 14, effectively preventing the storage bin 15 from shifting or falling off due to vibration during the sampling process, and ensuring the stable reception and collection of the sampled grains.

[0026] In a preferred embodiment, to enhance the overall stability of the device, the device also includes a telescopic rod 12 connected to the housing 1. The end of the telescopic rod 12 is provided with an anti-slip pad 13. The telescopic rod 12 is fixedly connected to the housing 1 via a fixing rod 11. By adjusting the length of the telescopic rod 12, the anti-slip pad 13 can be made to contact the ground stably.

[0027] In a preferred embodiment, in order to achieve automatic dispersion and sampling of grain, the sampling mechanism includes a motor 4 and a rotating disk 5 driven by the motor 4. A conical cylinder 8 is fixedly installed on the rotating disk 5, and the conical outer surface of the conical cylinder 8 is used to initially disperse the falling grain.

[0028] In a preferred embodiment, in order to achieve synchronous rotation of the rotating disk 5 and the conical cylinder 8, the sample separating mechanism also includes a connecting rod 7, one end of which is fixedly connected to the rotating disk 5 and the other end of which is fixedly connected to the conical cylinder 8.

[0029] As a preferred implementation method, in order to further improve the uniformity of sample distribution, a rib 9 surrounding the conical cylinder 8 is fixedly connected to the rotating disk 5, and a rib plate 6 is integrally formed on the rotating disk 5.

[0030] In a preferred embodiment, in order to protect the motor 4, the device also includes a baffle 10, which is fixedly disposed between the upper part of the motor 4 and the lower part of the sample dispensing mechanism.

[0031] In a preferred embodiment, in order to facilitate the filling and removal of grain, a feed inlet 2 is provided on the top of the box 1, a feed hopper 3 is connected to the feed inlet 2, and a handle 16 is fixedly connected to the outer wall of the storage box 15.

[0032] Working principle: The grain to be sampled is fed into the device through the feed hopper 3 and feed inlet 2. At the same time, the telescopic rod 12 extends to bring the anti-slip pad 13 into contact with the ground. The telescopic rod 12 and the box 1 are connected by the fixing rod 11 to enhance the stability of the device. After the storage box 15 is placed below the discharge bin 14, the slider 17 inside the discharge bin 14 slides down. The slider 17 will press the elastic locking block 18 on the storage box 15. The elastic locking block 18 locks the slider 17, thus firmly fixing the storage box 15. The motor 4 is started, and the motor 4 drives the rotating disk 5 to start rotating. The rotating disk 5 drives the conical cylinder 8, the prism plate 6, and the prism rod 9 to move synchronously through the connecting rod 7, continuously dispersing and sampling the falling grain. The sampled grain enters the discharge bin 14 and falls into the fixed storage box 15. Through the support of the telescopic rod 12 and the anti-slip pad 13, and the coordinated locking effect of the slider 17 and the elastic locking block 18, this utility model effectively solves the problems of insufficient stability caused by device vibration and loose connection of the storage box in the prior art, ensuring the stability of the sampling operation and the reliability of sample collection.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
