Description

Technical Field

[0001] This utility model relates to the field of seed cleaning technology, and in particular to a watermelon seed cleaning and sorting device. Background Technology

[0002] Before sowing watermelon seeds, their surfaces need to be cleaned. Watermelon seeds may have dirt, impurities, and other contaminants attached to them. These contaminants not only affect the cleanliness of the seeds but may also carry pathogens, hindering healthy growth. Cleaning effectively removes these contaminants and pathogens, reducing the occurrence of seedling diseases and thus improving the germination rate, allowing the seeds to grow healthily.

[0003] However, in the existing technology, after washing watermelon seeds, it is still necessary to sort the seeds to remove inferior seeds and keep the superior ones. The current seed sorting work is mostly done manually, and when there are a lot of watermelon seeds to wash, the manual sorting method is generally inefficient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: most seed sorting is done manually, and manual sorting is generally inefficient when there are many watermelon seeds to be cleaned.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a watermelon seed cleaning and sorting device, comprising a platform, a soaking tank being fixedly mounted through the surface of the platform, and a liquid discharge port being provided at the lower end of the soaking tank. A valve is fixedly installed on the surface of the liquid discharge port. A first electric telescopic rod is fixedly mounted on the outer surface of the soaking tank, and a fixing block is fixedly mounted at one end of the first electric telescopic rod. A second electric telescopic rod is fixedly mounted on the surface of the fixing block, and a connecting arm is fixedly connected to the telescopic end of the second electric telescopic rod. A sorting frame is fixedly mounted at one end of the connecting arm, and a drain cover is rotatably connected to the top edge of the sorting frame. A fixing rod is fixedly mounted on the side of the sorting frame, and a through-plug is slidably connected to the fixing rod, and the through-plug engages with the side of the drain cover.

[0006] In a preferred embodiment, a blocking plate is fixedly connected to one end of the fixing rod.

[0007] In a preferred embodiment, a water tank is fixedly connected to the surface of the placement platform on one side of the soaking tank, and a water pump is fixedly connected to the surface of the water tank. Both the output end and the input end of the water pump are fixedly connected to a conveying rigid pipe, and the conveying rigid pipe located at the lower end of the water pump is fixedly connected to the water tank through it.

[0008] In a preferred embodiment, a support is fixedly connected to the outer surface of the conveying rigid pipe above the soaking tank, and one end of the support is fixedly connected to the placement platform.

[0009] In a preferred embodiment, a flexible tube is fixedly connected to one end of the conveying rigid tube located directly above the drain cover.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This invention involves filling a soaking tank with brine, then placing watermelon seeds to be cleaned into a sorting frame. The opening at the top of the sorting frame is then closed by rotating a perforated cap, which is secured to the cap with a insert to improve stability. The sorting frame is then lowered using a first-order electric telescopic rod, immersing it in the brine to clean the watermelon seeds and remove impurities and pathogens. Once the seeds are cleaned, the sorting frame is raised to remove them from the brine. Two second-order electric telescopic rods are then used to move the connecting arm and sorting frame left and right, causing the shriveled and small inferior seeds to fall out. This process separates plump, high-quality seeds from the sorting frame, eliminating the need for manual sorting and making the process simple and quick. Attached Figure Description

[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. 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.

[0018] Example 1

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a watermelon seed washing and sorting device, including a platform 1, a soaking tank 2 fixedly fixed through the surface of the platform 1, the soaking tank 2 being used to hold brine for soaking and washing watermelon seeds, and a discharge port 3 being provided at the lower end of the soaking tank 2, a valve being fixedly installed on the surface of the discharge port 3, by opening the valve on the discharge port 3, the brine used to wash watermelon seeds and the screened inferior seeds can be quickly discharged out of the soaking tank 2, and an electric telescopic rod 4 is fixedly fixed to the outer surface of the soaking tank 2. Rod 4 serves to move the fixed block 5, the second electric telescopic rod 6, the connecting arm 7, and the sorting frame 8 up and down. The retraction of the first electric telescopic rod 4 causes the sorting frame 8 containing watermelon seeds to move downwards and be immersed in the brine of the soaking tank 2 for soaking and cleaning. A fixed block 5 is fixed to one end of the first electric telescopic rod 4. The fixed block 5 facilitates the fixed installation of the second electric telescopic rod 6 at one end of the first electric telescopic rod 4. The second electric telescopic rod 6 is fixed to the surface of the fixed block 5, and a connecting arm 7 is fixedly connected to the telescopic end of the second electric telescopic rod 6. A sorting frame 8 is fixed to one end. When the watermelon seeds have finished soaking and washing, the sorting frame 8 is moved upward to remove the watermelon seeds from the salt water. Then, the two No. 2 electric telescopic rods 6 are controlled to extend and retract back and forth, causing the connecting arm 7 and the sorting frame 8 to sway left and right, allowing the shriveled and small inferior seeds to fall out of the sorting frame 8. Thus, the plump and high-quality seeds are sorted out in the sorting frame 8. A drain cover 9 is rotatably connected to the top edge of the sorting frame 8. A fixing rod 10 is fixed to the side of the sorting frame 8, and a through-plug 11 is slidably connected to the fixing rod 10. The through-plug 11 is connected to the drain. The sides of the cover 9 are engaged. Before watermelon seeds are placed into the sorting frame 8 and soaked in salt water, the drain cover 9 is rotated to seal the opening of the sorting frame 8. This effectively prevents watermelon seeds from falling from the sorting frame 8 into the soaking tank 2 while soaking in salt water, which would prevent the sorting frame 8 from scooping all the watermelon seeds out of the salt water for subsequent screening. After the drain cover 9 seals the opening of the sorting frame 8, the stability of the drain cover 9 when sealing the sorting frame 8 is improved by allowing the insert 11 to slide on the fixing rod 10 and engage with the drain cover 9.

[0020] Example 2

[0021] like Figure 1-3 As shown, a baffle plate 12 is fixedly connected to one end of the fixing rod 10. The baffle plate 12 blocks the movement of the through-plug 11, effectively preventing the through-plug 11 from accidentally detaching from the fixing rod 10 and being lost. A water tank 13 is fixedly connected to the surface of the placement platform 1 on one side of the soaking tank 2, and a water pump 14 is fixedly connected to the surface of the water tank 13. Both the output and input ends of the water pump 14 are fixedly connected to conveying hard pipes 15, and the conveying hard pipe 15 located at the lower end of the water pump 14 is fixedly connected to the water tank 13. When the watermelon seeds are taken out of the brine for sorting, the water pump 14 is turned on, so that the clean water in the water tank 13 is drawn into the conveying hard pipe 15. Finally, the clean water flows out from the end of the conveying hard pipe 15 above the drain cover 9. The water sprayed from the mouth passes through the drain cover 9 to wash the watermelon seeds in the sorting box 8, removing the residual salt. The conveying rigid pipe 15 is fixedly connected to the bracket 16 on the outer surface above the soaking tank 2, and one end of the bracket 16 is fixedly connected to the mounting platform 1. The bracket 16 supports the conveying rigid pipe 15 above the soaking tank 2, making its installation more stable. The end of the conveying rigid pipe 15 located directly above the drain cover 9 is fixedly connected to the hose 17. The water conveyed by the conveying rigid pipe 15 is sprayed out from the lower end of the hose 17. Since the hose 17 is flexible, the user can swing it to change the landing point of the water after it is sprayed out, thereby expanding the rinsing range of the watermelon seeds and making it easier to clean the watermelon seeds more thoroughly.

[0022] Working principle:

[0023] like Figure 1-3 As shown, when using this utility model, the user first pours a 2% concentration of salt water into the soaking tank 2, and the temperature of the salt water is equal to the room temperature, so as to facilitate better soaking and cleaning later. Then, the watermelon seeds to be cleaned are placed in the sorting frame 8. Then, the drain cover 9 is rotated to close the opening of the sorting frame 8. Next, the through plug 11 on the fixing rod 10 is pushed to engage with the drain cover 9. Then, the first electric telescopic rod 4 is controlled to retract, which drives the fixing block 5, the second electric telescopic rod 6, the connecting arm 7 and the sorting frame 8 to move down. The sorting frame 8 moves down into the salt water, allowing the watermelon seeds to be soaked and cleaned in the salt water to remove impurities and bacteria from their surface.

[0024] After the watermelon seeds have been soaked and cleaned for a period of time, the sorting frame 8 is moved upward to remove the watermelon seeds from the salt water. Then, the two No. 2 electric telescopic rods 6 are controlled to extend and retract back and forth, causing the connecting arm 7 and the sorting frame 8 to sway left and right, allowing the shriveled and small inferior seeds to fall out of the sorting frame 8. This separates the plump and high-quality seeds from the sorting frame 8. While sorting the watermelon seeds, the water pump 14 is turned on to draw clean water from the water tank 13. The clean water is then conveyed through the conveying pipe 15 and finally sprayed out from the port of the hose 17. The user then drags the hose 17 to allow the clean water to rinse every part of the drain cover 9. The clean water flows through the holes in the drain cover 9 into the sorting frame 8 to clean the sorted superior watermelon seeds and wash away the residual salt.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
