Abstract
Description
Technical Field
[0001] This utility model relates to the field of sample divider technology, and more specifically, to a sample divider suitable for seeds of different sizes. Background Technology
[0002] A seed divider is a device used in agriculture and plant research to divide seeds into uniform portions. It ensures the representativeness and consistency of the samples, and is of great significance for seed quality testing and breeding research.
[0003] When separating seeds of different sizes, the sampler typically uses a pull-out switch at the inlet to control the size of the outlet. A hopper with its pointed tip is usually located directly below the outlet. Using a pull-out switch can cause a misalignment between the outlet and the pointed tip of the hopper when controlling the inlet size, affecting the separation efficiency. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a sampler that is suitable for seeds of different sizes and can ensure that the seeds always fall to the center of the top of the sampler hopper, thus ensuring the uniformity of sample distribution.
[0005] To solve the above problems, the present invention adopts the following technical solution.
[0006] A sampler suitable for seeds of different sizes, comprising:
[0007] A storage hopper for storing seeds, and a discharge port for discharging the seeds is provided at the bottom of the storage hopper;
[0008] A receiving hopper is located below the storage hopper and is used to receive seeds from the storage hopper; the top of the receiving hopper is provided with a receiving port corresponding to the discharge port, and the bottom is provided with at least two sampling ports;
[0009] An extended feed pipe is provided, with one end connected to the outlet and the other end adjustable and positioned within the receiving port to guide the seeds from the outlet into the receiving hopper.
[0010] The sample hopper is located inside the receiving hopper and has a pointed top. The pointed top of the sample hopper is directly opposite to and partially inserted into the extended feed pipe to evenly distribute the seeds into each sample inlet.
[0011] Preferably, the extended feed tube is threaded into the receiving port.
[0012] Preferably, an adjusting ring is rotatably connected to the top of the receiving port, and the extended feed pipe is threaded into the adjusting ring.
[0013] Preferably, the outer wall of the upper half of the extended feed tube is provided with threads, and the outer wall of the lower half is provided with a guide bar that vertically guides and cooperates with the inner wall of the feed inlet.
[0014] Preferably, a switch for opening and closing the discharge port is provided between the extended feed pipe and the storage hopper.
[0015] Preferably, the sample hopper is a cone-shaped structure with the tip pointing upwards, and a number of evenly spaced grid strips are arranged around the outer side wall of the bottom of the sample hopper.
[0016] Preferably, the bottom of the sample hopper is provided with at least one partition in the middle to evenly divide the bottom of the receiving hopper.
[0017] Compared with the prior art, the advantages of this utility model are as follows:
[0018] By raising the extended feed pipe, the bottom of the extended feed pipe can be moved away from the top of the sample hopper, thereby expanding the discharge space at the bottom of the extended feed pipe; by lowering the extended feed pipe, the bottom of the extended feed pipe can be moved closer to the top of the sample hopper, thereby reducing the discharge space at the bottom of the extended feed pipe. Regardless of whether the extended feed pipe is raised or lowered, it always corresponds directly to the top of the sample hopper. This allows it to be used for seeds of different sizes while ensuring that the seeds always fall at the top of the sample hopper without deviation, thus guaranteeing a uniform sample distribution.

[0027] 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.
[0028] refer to Figure 1-4 A sampler suitable for seeds of different sizes includes: a storage hopper 1, a receiving bin 2, an extended feed pipe 3, and a sample dispensing hopper 4. The storage hopper 1 stores seeds, and its bottom has a discharge port 11 for discharging. The receiving bin 2 is located below the storage hopper 1 and receives seeds from it; its top has a receiving port 21 corresponding to the discharge port 11, and its bottom has at least two sample dispensing ports 22. One end of the extended feed pipe 3 is connected to the discharge port 11, and the other end is adjustable and positioned within the receiving port 21 to guide seeds from the discharge port 11 into the receiving bin 2. The sample dispensing hopper 4 is located within the receiving bin 2, with a pointed top; the pointed top of the sample dispensing hopper 4 is directly and partially inserted into the extended feed pipe 3 to evenly distribute seeds into each sample dispensing port 22.
[0029] Understandably, the storage hopper 1 is a component for storing seeds, and can be, for example, a square hopper structure or a conical hopper structure, but is not limited to these. The receiving hopper 2 is a component for installing the sample dispensing hopper 4, and can be, for example, a hopper structure with upper and lower conical shapes, or a cylindrical hopper structure, but is not limited to these. The extension feed pipe 3 is a component for guiding seeds to the top of the sample dispensing hopper 4, and can be a round pipe structure or a square pipe structure, but is not limited to these. The lifting and adjusting of the extension feed pipe 3 can adopt a threaded structure, a gear and rack structure, or a sliding structure such as a guide groove 211 and a guide bar 31, combined with a telescopic drive component such as an electric push rod, but is not limited to these. The sample dispensing hopper 4 is a sample dispensing component with a conical top, which can be statically fixed, or can be rotated about the central axis of the sample dispensing hopper 4, etc., but is not limited to these.
[0030] With this setup, seeds are placed in the storage hopper 1, and then enter the extended feed pipe 3 through the inlet. The extended feed pipe 3 guides the seeds to fall onto the sampling hopper 4 for sampling, and finally discharges evenly from the individual sampling ports 22. When sampling seeds of different sizes, the extended feed pipe 3 can be raised to move its bottom away from the top of the sampling hopper 4, thereby expanding the discharge space at the bottom of the extended feed pipe 3; conversely, it can be lowered to move its bottom closer to the top of the sampling hopper 4, thereby reducing the discharge space at the bottom of the extended feed pipe 3. Regardless of whether the extended feed pipe 3 is raised or lowered, it always corresponds directly to the top of the sampling hopper 4. This design is suitable for seeds of different sizes while ensuring that the seeds always fall onto the top of the sampling hopper 4 without deviation, thus guaranteeing the sampling effect.
[0031] In some embodiments, reference Figure 2-3 The extended feed tube 3 is threadedly engaged with the receiving port 21. Threads can be provided on the outer wall of the extended feed tube 3 and the inner wall of the receiving port 21. Thus, the height of the extended feed tube 3 can be adjusted by rotating it.
[0032] In some embodiments, reference Figure 3-5 An adjusting ring 5 is rotatably connected to the top of the receiving port 21, and the extended feed pipe 3 is threadedly connected inside the adjusting ring 5. Here, the adjusting ring 5 has a ring-shaped structure and internal threaded components. The rotatable connection between the adjusting ring 5 and the top of the receiving hopper can be achieved through an embedded structure of an annular groove 23 and an annular ring 42, or by installing a bearing inside the receiving port 21 and then placing the adjusting ring 5 on the inner ring of the bearing, etc., but is not limited to these methods. Thus, the height of the extended feed pipe 3 can be adjusted by rotating the adjusting ring 5.
[0033] In some embodiments, reference Figure 1 and Figure 3 The upper half of the extended feed tube 3 has threads on its outer wall, and the lower half has a vertical guide bar 31 on its outer wall. The inner wall of the receiving port 21 has a guide groove 211 that vertically guides the guide bar 31. Here, the cooperation between the guide groove 211 and the guide bar 31 can vertically limit and guide the extended feed tube 3, and also prevent the extended feed tube 3 from rotating. With the help of the adjusting ring 5, the extended feed tube 3 can be raised and lowered for adjustment.
[0034] In some embodiments, a switch 6 for opening and closing the discharge port 11 is provided between the extended feed pipe 3 and the storage hopper 1. The switch 6 can be a slide gate or a butterfly valve, but is not limited to these. In this way, the discharge port 11 can be opened and closed by the switch 6, thereby controlling the opening and closing of the sample separation.
[0035] In some embodiments, reference Figure 3 and Figure 6 The sample dispensing hopper 4 is a cone-shaped structure with its tip pointing upwards. Several evenly spaced grid strips 41 are arranged around the outer bottom wall of the sample dispensing hopper 4. The grid strips 41 divide the sample dispensing hopper 4 and the inner wall of the receiving bin 2 into several channels of uniform size. Seeds are evenly dispersed from the top of the sample dispensing hopper 4 into each channel, and then discharged through the sample dispensing port 22. Furthermore, at least one partition 7 is provided in the middle of the bottom of the sample dispensing hopper 4, evenly dividing the bottom of the receiving bin 2. This partition 7 separates the corresponding channels at the bottom of the receiving hopper, thereby creating the sample dispensing ports 22, ensuring that each sample dispensing port 22 is isolated from the others and does not interfere with them.
[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
