Description

Technical Field

[0001] The utility model relates to the field of grain weed identification, and more specifically, to a multi-channel rapid identification device for weeds in imported grain. Background Art

[0002] Grain weed identification is an important link in agricultural production, which involves accurately identifying and classifying non-target plant species mixed in grain. This process is of great significance for ensuring grain quality, reducing storage losses, and maintaining ecological balance. During identification, professionals will accurately identify weeds based on their morphological characteristics (such as leaf shape, stem texture, inflorescence type, etc.), growth habits, and biological characteristics, in combination with relevant literature or using modern biotechnology means (such as DNA barcoding technology) to ensure the purity and safety of the grain.

[0003] Currently, grain weed identification devices face two major challenges during operation: Firstly, the single-channel design greatly limits the processing efficiency and is difficult to meet the urgent need for efficient and rapid identification in large-scale grain processing;

[0004] Secondly, weeds are prone to accumulate and cause blockage in the feeding pipe during transportation. This problem not only exacerbates operation interruptions and delays but also seriously affects the accuracy of weed identification and the identification effect of the device.

[0005] Therefore, we have made improvements and proposed a multi-channel rapid identification device for weeds in imported grain. Summary of the Utility Model

The bottom of the aggregate hopper is fixedly installed with three feeding pipes, and a stirring mechanism is arranged inside the aggregate hopper. A shearing mechanism is arranged inside the fixed frame. A conveying mechanism is arranged inside the bottom frame, and a connecting mechanism is arranged between the conveying mechanism and the stirring mechanism. An image recognition mechanism is fixedly installed on the top of the fixed frame;

[0011] The stirring mechanism includes a rotating shaft, and the rotating shaft is rotatably connected inside the aggregate hopper. A stirring rod is fixedly installed on the outer surface of the rotating shaft.

There are two reciprocating lead screws, and both reciprocating lead screws are rotatably connected inside the fixed frame. Both ends of the reciprocating lead screw are threadedly connected with a sliding plate, and a cutting knife is fixedly installed on one side surface of both sliding plates.

[0013] As a preferred technical solution of the present application, fixed rods are fixedly installed on both the upper and lower sides of the reciprocating lead screw, and the fixed rods are fixedly installed between the fixed frames. The connection mode between the sliding plate and the fixed rod is a sliding connection.

[0014] As a preferred technical solution of the present application, sprockets are fixedly installed at one end of both reciprocating lead screws, and the two sprockets are rotationally connected by a chain. A fixed cover is fixedly installed on one side surface of the fixed frame, and a first motor is fixedly installed on one side surface of the fixed cover. The output end of the first motor is fixedly connected to one end of the reciprocating lead screw on one side.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] In the solution of the present application:

[0020] 1. By setting up three feeding pipes and using three conveyors, the grain weed identification device can significantly improve processing efficiency and stability. This improvement enables the grain flow to be dispersed into three independent channels, effectively reducing the risk of blockage in a single channel feeding pipe, because even if a channel is slightly blocked, the other channels can continue to work without affecting the overall process; at the same time, the multi-feeding pipe design also promotes the uniform distribution of grain, making weeds more dispersed during transportation, which is conducive to the precise identification and removal of subsequent identification equipment, thereby improving the effect and accuracy of weed identification.

[0021] 2. Through the use of the stirring mechanism, the bottom of the collecting hopper can be stirred to break up the weeds and avoid weeds from clogging the bottom of the collecting hopper. Through the use of the shearing mechanism, when the weeds pass through the lower hopper, the slides on both sides can move relative to each other, driving the cutters on the surface to move. The cutters on both sides can cut the clumped weeds and spread them out, which is convenient for subsequent weed identification and avoids the clumping of weeds affecting the identification of weeds.

[0037] Combined with Figure 1 - Figure 6 As shown, a multi-channel rapid identification device for weeds in imported grain provided by the present utility model includes a bottom frame 1. A fixed frame 2 is fixedly installed at the top of one side of the bottom frame 1, and an aggregate hopper 3 is fixedly installed inside the fixed frame 2. Three feeding pipes 4 are fixedly installed at the bottom of the aggregate hopper 3, and a stirring mechanism 5 is arranged inside the aggregate hopper 3. A shearing mechanism 6 is arranged inside the fixed frame 2. A conveying mechanism 7 is arranged inside the bottom frame 1, and a connecting mechanism 8 is arranged between the conveying mechanism 7 and the stirring mechanism 5. An image recognition mechanism 9 is fixedly installed at the top of the fixed frame 2; the stirring mechanism 5 includes a rotating shaft 501, and the rotating shaft 501 is rotatably connected inside the aggregate hopper 3. A stirring rod 502 is fixedly installed on the outer surface of the rotating shaft 501.

[0038] In this embodiment: Three feeding pipes 4 are fixedly installed at the bottom of the aggregate hopper 3, which means that the grain can be shunted through different channels, improving the processing efficiency. The rotating shaft 501 is rotatably connected inside the aggregate hopper 3 and can drive the stirring rod 502 on its surface to rotate. When the weeds are poured into the aggregate hopper 3, the weeds at the bottom will be stirred, playing a role in breaking up and preventing blockage at the feeding pipe 4.
