Description

Technical Field

[0001] This utility model relates to the field of potato seed screening technology, specifically a seed pre-screening device for potato planting. Background Technology

[0002] Potatoes are the world's fourth most important food crop, and are widely cultivated in my country. During potato cultivation, seed quality directly affects potato yield and quality. Therefore, pre-screening of potato seeds is necessary before planting to remove impurities, damaged seeds, and seeds that do not meet size requirements, in order to ensure germination rate and uniform growth after planting.

[0003] In existing technology, seeds are laid on a conveyor belt, and during the conveying process, workers screen the seeds to ensure that the selected seeds are stable during subsequent planting.

[0004] However, in actual use, since the number of seeds selected each time is large and the seeds are similar in size, the screening effect will be reduced by the staff's observation. Over time, this will also reduce the staff's work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a seed pre-screening device for potato cultivation, which solves the problem that in actual use, due to the large number of seeds selected each time and the similar size of the seeds, screening by observation by staff leads to a decrease in screening effectiveness and, over time, a decrease in the work efficiency of staff.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a seed pre-screening device for potato planting, comprising a workbench, a conveying plate fixedly connected to the top of the workbench, a material box fixedly connected to one side of the top of the conveying plate, a conveying roller installed on the other side of the top of the conveying plate, a baffle provided on one side of the outer wall of the conveying roller, the bottom of the baffle fixedly connected to the top of the conveying plate, a fixing plate provided on the other side of the conveying roller, and a sorting component installed on the inner wall of the fixing plate.

[0007] Preferably, the sorting component includes a chute, which is formed on the outer wall of the fixed plate. A slider is slidably engaged with the inner wall of the chute, and an adjusting plate is fixedly connected to the outer wall of the slider. The inner wall of the adjusting plate is provided with screening holes.

[0008] Preferably, an installation groove is provided on the top of the workbench on the side away from the material box, and a recycling box is inserted into the inner wall of the installation groove.

[0010] Preferably, a limiting plate is fixedly connected to the outer wall of the recycling bin, a support plate is pressed against the bottom of the limiting plate, the outer wall of the support plate is fixedly connected to the outer wall of the workbench, and an insert is fixedly connected to the top of the support plate, with the outer wall of the insert being inserted into the inner wall of the limiting plate.

[0011] Beneficial effects

[0012] This invention provides a seed pre-screening device for potato cultivation. It offers the following advantages: Through the cooperation of a conveyor plate, a fixed plate, and sorting components, this seed pre-screening device allows all seeds to be placed into a hopper during sorting. Driven by conveyor rollers, the seeds move on the conveyor plate, and the sorting components on the fixed plate separate qualified seeds. This not only ensures accurate sorting but also improves worker efficiency. It solves the problem that when selecting a large quantity of seeds of similar size, relying on manual observation for screening can reduce the effectiveness of the screening process and, over time, decrease worker efficiency.

[0013] By using the connection hole, discharge pipe and connection hole in combination, when the air separation component sorts out qualified seeds, they will enter the discharge pipe through the connection hole and then enter the collection box through the discharge pipe. This ensures that the seeds will not be damaged during collection and solves the problem that existing sorting devices are prone to seed damage when sorting seeds. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] In practical use, since the number of seeds selected each time is large and the seeds are similar in size, the screening effect will be reduced by staff observation, and over time it will also reduce the work efficiency of the staff.

[0021] In view of this, the present invention provides a seed pre-screening device for potato planting, which solves the problem that in actual use, due to the large number of seeds selected each time and the similar size of the seeds, screening by observation by staff will reduce the screening effect and, over time, reduce the work efficiency of staff.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 It is known that a seed pre-screening device for potato planting includes a workbench 1, a conveyor plate 2 fixedly connected to the top of the workbench 1, a material box 3 fixedly connected to one side of the top of the conveyor plate 2, a conveyor roller 4 installed on the other side of the top of the conveyor plate 2, a baffle 5 provided on one side of the outer wall of the conveyor roller 4, the bottom of the baffle 5 fixedly connected to the top of the conveyor plate 2, a fixing plate 6 provided on the other side of the conveyor roller 4, and a sorting component installed on the inner wall of the fixing plate 6.

[0024] In the specific implementation process, it is worth noting that the top of the conveyor plate 2 is sloping, with the side facing the fixed plate 6 being lower and the other side being higher. This allows the seeds to move towards the fixed plate 6. Furthermore, multiple conveyor rollers 4 are provided, and their installation angle is the same as that of the conveyor plate 2, ensuring that the seeds move towards the fixed plate 6 simultaneously while being conveyed forward, thus stabilizing the seeds during conveying and sorting. A drive device is installed on the outer wall of the conveyor rollers 4, which drives the conveyor rollers 4 to rotate on top of the conveyor plate 2, ensuring stable seed conveying. The baffle 5 on the other side of the conveyor plate 2 prevents seeds from falling during screening. The sorting component can accurately sort out seeds smaller than the specified size, preventing oversized seeds from affecting sowing. When sorting seeds, the seeds are put into the material box 3, and the seeds in the material box 3 will slide onto the conveyor roller 4. The conveyor roller 4 moves forward under the drive of the drive device. Since the conveyor plate 2 and the conveyor roller 4 are sloped, the moving seeds will move against the fixed plate 6. At the same time, seeds smaller than the size set on the sorting component will be sorted out, while unqualified seeds will continue to move under the drive of the conveyor roller 4 and be transported to the recycling box 7. This not only makes the sorting accurate, but also improves the sorting speed of the workers.

[0025] Furthermore, the sorting component includes a chute 15, which is formed on the outer wall of the fixed plate 6. A slider 14 is slidably engaged on the inner wall of the chute 15. An adjusting plate 12 is fixedly connected to the outer wall of the slider 14. A screening hole 13 is formed on the inner wall of the adjusting plate 12.

[0026] In the specific implementation process, it is worth noting that the screening holes 13 on the surface of the adjustment plate 12 are limited according to the maximum size of the seeds to be screened, and seeds larger than the screening holes 13 will be selected. When changing different screening holes 13 and adjustment plates 12, the adjustment plate 12 can be quickly replaced by sliders 14 and grooves 15, which improves the work efficiency of the staff and ensures the accuracy of screening.

[0027] Furthermore, a mounting groove 19 is provided on the top side of the workbench 1 away from the material box 3, and a recycling box 7 is inserted into the inner wall of the mounting groove 19.

[0028] In the specific implementation process, it is worth noting that the recycling bin 7 is limited by the installation slot 19, which makes the recycling bin 7 easy to install, and the recycling bin 7 is used to collect the unqualified seeds that have been sorted out, which makes it convenient for the staff to process them in the subsequent process.

[0029] Example 2: From Figure 1-4It can be seen that a connection hole 10 is provided on the front side of the top of the workbench 1, and a discharge pipe 8 is connected to the bottom of the connection hole 10. The top of the discharge pipe 8 is fixedly connected to the bottom of the workbench 1, a collection box 9 is provided below the discharge pipe 8, and a baffle 11 is provided above the connection hole 10. The bottom of the baffle 11 is fixedly connected to the top of the workbench 1.

[0030] In the specific implementation process, it is worth noting that the connecting hole 10 can ensure that the sorted seeds enter the interior of the discharge pipe 8, and the material of the discharge pipe 8 is plastic, which can ensure that the seeds will not be damaged during the transportation process and ensure that the seeds enter the collection box 9 accurately, making it convenient for the staff to handle. The baffle 11 will ensure that the sorted seeds will fall accurately into the connecting hole 10, preventing them from slipping out of the workbench 1 during the falling process.

[0031] Furthermore, a limiting plate 17 is fixedly connected to the outer wall of the recycling bin 7, and a support plate 16 is pressed against the bottom of the limiting plate 17. The outer wall of the support plate 16 is fixedly connected to the outer wall of the workbench 1, and an insert block 18 is fixedly connected to the top of the support plate 16. The outer wall of the insert block 18 is inserted into the inner wall of the limiting plate 17.

[0032] In the specific implementation process, it is worth noting that when installing the recycling box 7, the limiting plate 17 on the outer wall of the recycling box 7 is pressed against the top of the support plate 16, and the insert block 18 is inserted into the inside of the limiting plate 17, thereby fixing the recycling box 7 to the outer wall of the workbench 1, making it convenient for the staff to replace the recycling box 7 to process unqualified seeds.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
