[0002] The grain seed horizontal sampler is used to control the sieving and sampling of grain seeds. When inspecting the quality of grains, in addition to taking a certain number of samples, whether the samples are fully mixed and whether the required representative samples are taken in the correct amount are also important factors affecting the grain seed inspection results.

[0003] For example, the authorized patent with publication number CN218239490U (modular grain sampler) includes: a support frame, several samplers for dividing grain into two equal portions, and several receiving boxes for receiving the divided grain; the support frame has several first openings for accommodating the samplers, two second openings for accommodating the samplers or receiving boxes, four third openings for accommodating the samplers or receiving boxes, and eight fourth openings for accommodating the receiving boxes; the first openings, two second openings, four third openings, and eight fourth openings are symmetrically arranged on the support frame; this utility model provides a modular grain sampler, which allows receiving boxes or samplers to be placed on the support frame according to the actual number of grain portions, so that grain can be divided into several equal portions as needed, without the need for staff to repeatedly divide the grain using the samplers, effectively improving the efficiency of grain sampling.

[0004] The existing technology mentioned above cannot pre-screen grains according to particle size during the sampling process, which makes its functionality insufficient. The quality of the sampling process is inconsistent, affecting the quality and effect of the sampling. Furthermore, the sampling efficiency is not stable enough, which can easily lead to more dust and dirt, resulting in a decline in environmental quality. Utility Model Content

[0005] The purpose of this invention is to provide a horizontal grain seed sampler to solve the problems mentioned in the background art, such as the inability to pre-screen grains according to particle size during the sampling process, resulting in insufficient functionality, inconsistent sampling quality, affecting the quality and effect of sampling, and unstable sampling efficiency, which easily leads to more dust and dirt and a decline in environmental quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a horizontal grain seed sampler, comprising a sieving hopper, a sample box, a storage box, and a sieve trough. The top of the sample box is provided with a sieving hopper via a support rod. The bottom of the sieving hopper is provided with multiple distributing heads. The interior of the sieving hopper is provided with a sieve trough. The bottom of the sieve trough is provided with a primary sieve plate, a secondary sieve plate, a tertiary sieve plate, a quaternary sieve plate, and a quinary sieve plate. The bottom of the sample box is provided with a guide trough, the bottom of which is connected to multiple receiving hoppers on the top of the storage box.

[0007] In a further embodiment, the screening hopper is provided with side ears on both sides, and the side ears are connected to the support rod.

[0008] In a further embodiment, the primary sieve plate, secondary sieve plate, tertiary sieve plate, quaternary sieve plate and quinary sieve plate are respectively arranged facing the multiple material distribution heads.

[0009] In a further embodiment, a limiting frame is also included, which is provided on both sides of the bottom of the sample box. The limiting frame is provided with limiting holes, and the top of the receiving hopper is directly opposite the limiting holes. The inside of the sample box is provided with a receiving port composed of multiple partitions.

[0010] In a further embodiment, the front of the storage bin is provided with multiple discharge ports, and the discharge ports are correspondingly arranged with the receiving hopper.

[0011] In a further embodiment, a feeding hopper is provided on one side of the top of the screening hopper, and the feeding hopper is positioned directly opposite the primary sieve plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The top of the sample box of this utility model is equipped with a sieve bucket via a support rod. A feeding hopper is provided on one side of the top of the sieve bucket, and a sieve groove is provided inside the sieve bucket. Multiple sieve plates with different apertures are provided at the bottom of the sieve groove, so that the incoming grain can be sieved and stored separately in the sieve plates. This process is completely sealed, which can prevent grain dust from floating in the air and causing air pollution.

[0014] 2. This utility model is equipped with multiple distributing heads, which can quantitatively discharge the sieved grain separately. The distributing heads are directly opposite the receiving ports, which allows the sampled grain to be stably classified and discharged. The grain can be stably guided into the receiving hopper through the guide channel and then discharged into the storage bin for storage, thereby increasing storage safety.
