Description

Technical Field

[0001] This utility model relates to the field of seed sampling technology, and more specifically, to an automatic sampling and conveying device for seed purity analysis. Background Technology

[0002] A horizontal sample divider is a device that divides a granular sample into two equal portions using intersecting, opposite-direction sliding tracks. It is primarily used for dividing granular materials such as seeds, grains, and feed. Its simple and practical construction results in minimal sampling error, and it is available in materials including stainless steel and powder-coated iron plates. The device achieves rapid sampling through a grooved arrangement, and different models are suitable for various particle sizes and weight ranges, making it suitable for both laboratory and agricultural production.

[0003] Existing horizontal sample dividers are not good at removing shriveled seeds and dust mixed in between seeds during the seed separation process. In addition, the sample pouring speed and state (such as flattening and uniform falling) need to be manually controlled during the separation process. Improper operation can easily lead to uneven separation. Therefore, we propose an automatic sample separation and conveying device for seed purity analysis to solve the above problems. Utility Model Content

[0004] 1. Technical problems to be solved In view of the problems existing in the prior art, the purpose of this utility model is to provide an automatic sample sorting and conveying device for seed purity analysis. It can not only effectively remove shriveled seeds and impurities such as dust, but also make the seeds fall at a uniform speed, so as to make the sample sorting uniform.

[0005] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0006] An automatic sample sorting and conveying device for seed purity analysis includes a sample sorting box and a discharge port opened on the top of the sample sorting box. The top edge of the sample sorting box is symmetrically and fixedly connected with brackets, and a drive roller and a driven roller are rotatably connected between the brackets respectively. A conveyor belt corresponding to the end of the drive roller and the driven roller is installed between the drive roller and the driven roller. A drive motor for driving the drive roller to rotate is installed on the bracket. The sample box has an assembly window at its end, and a fan is installed on the inside of the assembly window. A partition is fixedly connected at an angle to the inner side of the sample box. The partition has a through hole at the part corresponding to the discharge port. A screen is installed at an angle on one side of the through hole. The partition is provided with a sloping boss integrally formed with the sample box below it; The sample box is provided with a first discharge port and a second discharge port from top to bottom at the end away from the fan.

[0007] Furthermore, a support frame is symmetrically welded to the part of the bracket near the driven roller, and a guide hole is provided on the support frame. A tray integrally formed with the support frame is provided below the guide hole.

[0008] Furthermore, a material box is installed between the brackets, and a guide boss that slides and connects with the guide hole is installed on the side wall of the material box. A grid plate is welded to the bottom opening of the material box. A spring is installed between the grating plate and the support plate.

[0009] Furthermore, a vibration motor is installed on the outer surface of the material box.

[0010] Furthermore, a dustproof mesh cover is installed at the air inlet end of the fan.

[0011] Furthermore, the bottom end of the screen corresponds to the edge of the through hole away from the fan.

[0012] Furthermore, a collection bag is installed at the first discharge port.

[0013] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: (1) In this scheme, the active roller installed on the support is driven by the start of the drive motor, and the driven roller drives the conveyor belt to transport the seeds and drop them into the sample box through the discharge port. At the same time, the fan is turned on and the fan speed is adjusted. During the process of the seeds falling, the shriveled seeds and dust pass through the screen under the action of the airflow. At the same time, the screen is used to intercept the plump seeds. The screen is set at an angle, which is conducive to the plump seeds falling under the action of gravity. Finally, the seeds enter the bottom of the inner cavity of the sample box through the through hole and are discharged under the guidance of the inclined boss. This not only effectively removes shriveled seeds and dust and other impurities, but also makes the seeds fall at a uniform speed, so that the sample is evenly distributed.

[0014] (2) In this scheme, the seeds to be sampled are placed into the material box and the vibration motor is turned on at the same time. Under the elastic force of the spring installed on the tray, the seeds slide through the guide boss and the guide hole opened on the support frame, and the falling seeds are dispersed by the grid plate, so that the seeds fall evenly on the conveyor belt, preventing the seeds from gathering and falling in a concentrated manner, which is beneficial to the seed sampling work.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Example: Please see Figure 1-5 An automatic sample sorting and conveying device for seed purity analysis includes a sample sorting box 1 and a discharge port 2 opened on the top of the sample sorting box 1. The top edge of the sample sorting box 1 is symmetrically fixedly connected with a bracket 3, and a drive roller 4 and a driven roller 5 are rotatably connected between the brackets 3 respectively. A conveyor belt 6 corresponding to the end of the drive roller 4 and the driven roller 5 is installed between the drive roller 4 and the driven roller 5. A drive motor 7 for driving the drive roller 4 to rotate is installed on the bracket 3. The sample box 1 has an assembly window at its end, and a fan 8 is installed on the inside of the assembly window. A partition 10 is fixedly connected at an angle to the inner side of the sample box 1. A through hole 11 is opened on the partition 10 corresponding to the part of the discharge port 2. A screen 12 set at an angle is installed on one side of the through hole 11. Below the partition 10, there is a sloping boss 13 integrally formed with the sample box 1; The sample box 1, located away from the blower 8, has a first discharge port and a second discharge port respectively, from top to bottom. It should be noted that, in use, the automatic sample sorting and conveying device for seed purity analysis works by starting the drive motor 7 to rotate the active roller 4 mounted on the support 3, which in turn drives the conveyor belt 6 to transport the seeds through the feed port 2 into the sample sorting box 1. At the same time, the fan 8 is turned on and its speed is adjusted. During the seed falling process, shriveled seeds and dust pass through the screen 12 under the action of airflow, while the screen 12 traps plump seeds. The screen 12 is angled, which helps plump seeds fall under the action of gravity. Finally, the seeds enter the bottom of the inner cavity of the sample sorting box 1 through the through hole 11 and are discharged under the guidance of the inclined boss 13. This not only effectively removes shriveled seeds and dust and other impurities, but also ensures that the seeds fall at a uniform speed, resulting in uniform sample sorting.

[0019] like Figure 1 , Figure 5 As shown, a support frame 15 is symmetrically welded to the support frame 3 near the driven roller 5. A guide hole 16 is provided on the support frame 15. A support plate 17 integrally formed with the support frame 15 is provided below the guide hole 16. A material box 18 is installed between the supports 3. A guide boss 22 that is slidably connected to the guide hole 16 is installed on the side wall of the material box 18. A grid plate 19 is welded to the bottom opening of the material box 18. A spring 21 is installed between the grid plate 19 and the support plate 17. A vibration motor 20 is installed on the outer surface of the material box 18. It should be noted that by placing the seeds to be sampled into the material box 18 and simultaneously turning on the vibration motor 20, the seeds slide through the guide boss 22 in conjunction with the guide hole 16 on the support frame 15 under the elastic force of the spring 21 installed on the pallet 17, and are dispersed by the grid plate 19, so that the seeds fall evenly onto the conveyor belt 6, preventing the seeds from agglomerating and falling in a concentrated manner, which is beneficial to the seed sampling work.

[0020] like Figure 2 As shown, a dustproof mesh cover 9 is installed at the air inlet end of the fan 8; It should be noted that by setting up the dustproof net cover 9, impurities in the intake air are trapped, which has a good air purification effect.

[0021] like Figure 3 As shown, the bottom end of the screen 12 corresponds to the edge of the through hole 11 away from the blower 8; It should be noted that it not only effectively filters out shriveled seeds, but also causes the plump seeds that are trapped to fall under the influence of gravity.

[0022] like Figure 1 As shown, a collection bag 14 is installed at the first discharge port; It should be noted that it can effectively collect shriveled seeds and impurities such as dust.

[0023] In use: The drive motor 7 is started to drive the active roller 4 installed on the bracket 3 to rotate, and the driven roller 5 drives the conveyor belt 6 to transport the seeds. The seeds fall into the sample box 1 through the discharge port 2. At the same time, the fan 8 is turned on and the wind speed of the fan 8 is adjusted. During the falling process, shriveled seeds and dust pass through the screen 12 under the action of airflow. At the same time, the screen 12 is used to intercept the plump seeds. The screen 12 is set at an angle, which is conducive to the plump seeds falling under the action of gravity. Finally, the seeds enter the bottom of the inner cavity of the sample box 1 through the through hole 11 and are discharged under the guidance of the inclined boss 13.

[0024] 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.
