Description

Technical Field

[0001] This utility model relates to the field of seed production equipment technology, and in particular to a seed testing and sampling device. Background Technology

[0002] Seed cultivation is of paramount importance in ensuring crop yield. After a series of processing operations such as screening, washing, coating, and drying, seeds need to be stored in tanks. Once stored, seeds inside the tanks need to be sampled and tested regularly to prevent mold, necrosis, and other problems. This allows for the assessment of seed quality within the tank. Currently, seed sampling in tanks typically involves opening the inlet to sample seeds from the upper layer of the tank, or randomly sampling materials that fall at the outlet during seed discharge. This sampling process is not only laborious but also fails to sample seeds from all areas of the tank, potentially leading to unrepresentative results and affecting the staff's assessment of seed quality.

[0017] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-3 As shown, the seed detection and sampling device described in this embodiment includes a storage tank 1. The upper and lower ends of the storage tank 1 are provided with an inlet 2 and an outlet 3. Several samplers are arranged circumferentially on the side wall of the storage tank 1.

[0020] The sampler includes a cylindrical base 4 that is placed horizontally and penetrates the side wall of the storage tank 1. A retractable puncture tube 5 is provided inside the cylindrical base 4. Both ends of the puncture tube 5 extend out from both ends of the cylindrical base 4. A retractable sampling rod 6 is provided inside the puncture tube 5. The end of the sampling rod 6 located outside the storage tank 1 extends outward from the puncture tube 5. The portion of the sampling rod 6 located inside the storage tank 1 is provided with a sampling groove 6a. The portion of the puncture tube 5 located inside the storage tank 1 is provided with a sampling notch 5a at the position corresponding to the sampling groove 6a. The sampling notch 5a and the sampling groove 6a are interconnected.

[0021] A conical puncture head 7 is provided at one end of the puncture tube 5 located inside the storage tank 1. The puncture head 7 is sealed at one end of the puncture tube 5 located inside the storage tank 1. The end of the sampling rod 6 abuts against the end where the puncture head 7 is connected to the puncture tube 5. The puncture head 7 increases the penetration capability of the puncture tube 5, thereby facilitating seed sampling operations.

[0022] The bottom of the inner wall of the puncture tube 5 is provided with a raised slide rail 8 in the horizontal direction. The bottom of the sampling rod 6 is provided with a slide groove 6a that matches the slide rail 8. The slide groove 6a at the bottom of the sampling rod 6 is inserted along the slide rail 8. This ensures that the sampling rod 6 is inserted into the puncture tube 5 at one position, so that the positions of the sampling groove 6a and the sampling notch 5a can be kept in correspondence.

[0023] The puncture tube 5 is provided with a pull handle 9 at one end outside the storage tank 1. Controlling the pull handle 9 can control the puncture tube 5 to slide along the cylinder seat 4.

[0024] An operating head 10 is provided at one end of the sampling rod 6 located outside the puncture tube 5. The operating head 10 facilitates the staff to insert and withdraw the sampling rod 6 inside the puncture tube 5.

[0025] The samplers are staggered along the side wall of storage tank 1, and each sampler is set to a different length according to the requirements, so that the seeds in various locations inside storage tank 1 can be sampled.

[0026] Discharge valves 11 are installed at the discharge ports 3.

[0027] The bottom of the storage tank 1 is provided with support legs 12.

[0028] The working principle of this utility model is as follows: After processing, the seeds are stored in storage tank 1. As the storage time increases, the quality of the seeds in storage tank 1 needs to be tested. A sampler on storage tank 1 is randomly selected for sampling. The sampling personnel can hold the pull handle 9 and control the piercing tube 5 to pierce into storage tank 1 along the cylinder 4. As the part of the piercing tube 5 with the sampling notch 5a extends out of the cylinder 4 and into the seeds in storage tank 1, the stored seeds will fall into the sampling groove 6a in the internal sampling rod 6 along the sampling notch 5a. The sampling groove 6a collects the seeds. After sampling, the puncture tube 5 is pulled out, and the puncture head 7 at the end of the puncture tube 5 is controlled to enter the interior of the cylinder seat 4. Then, the operator holds the operating head 10 and pulls the sampling rod 6 out. After the sampling rod 6 is pulled out, the seed sample collected in the sampling slot 6a can be taken out. After sampling is completed, the sampling rod 6 is reinserted into the puncture tube 5 along the slide rail 8 on the puncture tube 5, and the sampling operation can be repeated. The whole process is convenient to operate, and the operator can sample the seeds in various positions in the storage tank 1, which improves the representativeness of the samples and makes the test data more accurate.

[0029] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
