Description
Technical Field
[0001] This utility model relates to the field of agricultural seedling technology, specifically to an integrated device for washing and drying pumpkin seeds. Background Technology
[0002] Pumpkin seeds are the reproductive organs of the pumpkin, usually located inside the pumpkin fruit. They are flat and oval in shape with a hard outer shell, and their color may be white, yellow, green, or black depending on the variety. They are the "embryos" of the pumpkin plant and can germinate and grow into new pumpkin plants under suitable conditions. Pumpkin seeds are best cleaned and dried to improve germination rate, extend storage time, and ensure food safety.
[0003] Currently, the industry generally adopts split-type processing equipment, with each process completed by independent equipment in segments. This means that the cleaning and drying processes are designed separately: the cleaning stage relies on an independent tank, while the drying stage needs to be transferred to a special equipment for processing.
[0004] The split-type processing equipment commonly used in the industry currently has the following technical defects: the washed pumpkin seeds are deposited at the bottom of the tank, and operators need to use a filter to scoop them out batch by batch and transfer them to the drying equipment. The connection between the equipment depends on manual intervention, which leads to reduced production efficiency, interruption of the operation process and high labor intensity.

[0034] Example
[0035] To address the technical problems in the background section, the following integrated device for washing and drying pumpkin seeds is provided:
[0036] Combination Figures 1-5 As shown, this utility model provides a pumpkin seed washing and drying integrated device, comprising: a base 100, an outer barrel 200 mounted on the top of the base 100, an outer filter barrel 600 fixedly installed inside the outer barrel 200, an inner filter barrel 500 placed inside the outer filter barrel 600, a lifting unit 300 fixedly installed on the rear side of the top of the base 100, a stirring unit 400 mounted on the lifting unit 300 that penetrates the inner filter barrel 500 and is installed and connected to the outer filter barrel 600, and a flow guiding unit 700 mounted on the bottom of the outer barrel 200 and installed and connected to the stirring unit 400; by using the outer barrel 200 as the outer shell structure and the outer filter barrel 600 as the outer filtration layer, the inner filter barrel 500 is also supported, and the inner filter barrel 500 is not... However, it can hold the pumpkin seeds to be cleaned and can also work with the outer filter bucket 600 to filter out the pumpkin pulp, ensuring that the pumpkin seeds remain in the inner filter bucket 500. Through the cooperation between the stirring unit 400 and the lifting unit 300, not only can the pumpkin seeds be cleaned and the pulp removed by stirring, but the inner filter bucket 500 can also be lifted to raise the cleaned pumpkin seeds for easy extraction by personnel. The flow guiding unit 700 can not only inject cleaning water from the bottom to achieve a certain backwashing effect, but also switch to the blower mode after cleaning to dry the cleaned pumpkin seeds, thus improving the operation performance of the device.
[0037] The lifting unit 300 includes a mounting frame 301 and a top plate 304; the mounting frame 301 is fixedly installed on the rear side of the top of the base 100, and the top plate 304 is slidably installed on the front side of the mounting frame 301; the mounting frame 301 is a support structure to realize the installation and bearing of the working components, and the hoisting operation of the mixing unit 400 is realized through the top plate 304.
[0038] The stirring unit 400 includes a rotating shaft 402, a docking kit 403, and stirring blades 405. The rotating shaft 402 is mounted on the bottom of the top plate 304. The docking kit 403 is rotatably installed on the bottom of the outer filter barrel 600. The docking kit 403 passes through the inner filter barrel 500 and docks with the rotating shaft 402. Limiting ports 406 are provided on both sides of the docking kit 403. The stirring blades 405 that dock with the limiting ports 406 are fixedly connected to the rotating shaft 402. The rotating shaft 402 synchronously drives the stirring blades 405 and the docking kit 403 to rotate synchronously, thereby completing the cleaning operation of the pumpkin seeds in the inner and outer filter barrels.
[0039] The flow guiding unit 700 includes a three-way pipe 701 and a fan 704. The bottom of the outer barrel 200 is connected to the three-way pipe 701, which is connected to the docking kit 403. The top of the base 100 is fixedly installed with the fan 704, and the output end of the fan 704 is connected to one end of the three-way pipe 701.
[0040] Air is blown in by the blower 704 and diverted to the docking kit 403 through the three-way pipe 701, thus sending air into the filter canister.
[0041] In this embodiment, the lifting unit 300 further includes a guide rail 303 and a driving component 305. The front of the mounting frame 301 is provided with the guide rail 303, and the guide rail 303 is slidably connected to the top plate 304. The mounting frame 301 between the guide rails 303 is provided with a guide opening 302. The back of the mounting frame 301 is equipped with the driving component 305, and the driving component 305 is used to drive the top plate 304.
[0042] The top plate 304 is driven to move up and down by a drive component. The back of the top plate 304 has a guide port 302. The drive component 305 consists of a motor and a lead screw. The lead screw passes through the top plate 304 by a thread. The motor that drives the lead screw is also fixed on the mounting bracket 301. This is a commonly used transmission method nowadays.
[0043] In this embodiment, the stirring unit 400 also includes a motor 401, a rubber sleeve 404, and a rubber sleeve 407. The motor 401 is fixedly installed on the top plate 304. The top end of the rotating shaft 402 is connected to the output end of the motor 401. The rubber sleeve 407 is fitted on the rotating shaft 402, and the rubber sleeve 404 is wrapped around the stirring blade 405.
[0044] The motor 401 drives the rotating shaft 402 to rotate, which in turn drives the stirring blade 405 to rotate synchronously. Since the stirring blade 405 is limited by the limiting port 406 on the docking kit 403, it can synchronously drive the docking kit 403 to rotate. The rubber sleeve 407 can ensure the sealing effect between the rotating shaft 402 and the docking kit 403. The rubber sleeve 404 can reduce damage to the pumpkin seeds.
[0045] In this embodiment, a limiting ring 501 is fixedly installed at the top of the inner filter tank 500, and the stirring blade 405 extends to the bottom of the limiting ring 501.
[0046] When the stirring blade 405 rises, the two ends of the stirring blade 405 will drive the inner filter barrel 500 to rise through the limiting ring 501, and the inner filter barrel 500 after rising will make it easier for personnel to extract pumpkin seeds.
[0047] In this embodiment, a shaft seat 601 is fixedly installed on the top of the outer filter barrel 600, and the docking kit 403 is rotatably connected to the shaft seat 601.
[0048] The shaft seat 601 ensures the rotation of the docking kit 403, and ensures that the docking kit 403 can pass through the shaft seat 601 and dock with the top of the tee tube 701.
[0049] In this embodiment, the two ends of the three-way pipe 701 are equipped with manual valves 703 for use, and the top end of the three-way pipe 701 is fitted with a rotary joint 702 that is rotatably connected to the docking kit 403.
[0050] The manual valve 703 allows personnel to easily switch the flow direction of the three-way pipe 701; the rotary joint ensures the rotatable connection between the docking kit 403 and the three-way pipe 701, so that air or clean water entering through the three-way pipe 701 can simultaneously enter the docking kit 403.
[0051] Working principle and usage process of this utility model:
[0052] The motor in this application is connected to an external control system via wires. The control system can be centrally controlled by a PLC, and the motor is an existing device.
[0053] When in use, connect the external water supply pipe to the water inlet end of the three-way pipe 701, close the valve on the three-way pipe 701 at the air guide end, open the valve at the water injection end, and inject clean water into the three-way pipe 701. In this way, through the connection effect between the three-way pipe 701 and the docking kit 403, clean water is ensured to enter the bucket. Personnel then guide the pumpkin seeds into the inner filter bucket 500.
[0054] The second step involves activating the drive component 305 on the lifting unit 300. The motor in the drive component 305 drives the top plate 304 to descend, causing the bottom rotating shaft 402 to descend as well. Simultaneously, the inner filter bucket 500, which is suspended and limited by a limit ring, also descends. During descent, because the stirring blades 405 on the rotating shaft 402 are aligned with the limit port 406, it is ensured that the filter bucket descends along the limit port 406. Once the bottom is reached, the motor is activated to rotate the rotating shaft 402, thus stimulating the pumpkin inside the bucket. The pumpkin seeds are stirred and cleaned, and the pulp is separated from them. During this process, the pulp is broken up and dissolved in the water, and the pumpkin seeds float to the surface. Then, the water is drained through the drain outlet on the back of the bucket. The pulp liquid is discharged through the filter bucket, while the pumpkin seeds remain in the filter bucket. Then, the stirring unit is driven to rise again, the inner filter bucket 500 is raised, the limiting port 406 is exposed, and the rotating shaft 402 is also released from the blockage at the bottom of the docking kit 403. The above steps are repeated to inject clean water for a second rinse.
[0055] The third step is to drain the water after rinsing, allowing the water in the three-way pipe 701 to flow back. Then, close the valve at the water inlet end and open the valve at the air drying end to drive the stirring unit to rise. The inner filter barrel 500 is raised synchronously through the lifting limit ring, exposing the limit port 406. The rotating shaft 402 is also unblocked from the bottom of the docking kit 403. Finally, the blower 704 can be started to blow air and dry the pumpkin seeds. Air will enter through the three-way pipe 701, the docking kit 304 and the limit port 406 on the kit, and the pumpkin seeds will be dried along with the stirring. Finally, the lifting unit 300 maximizes the lifting of the stirring unit, and the two ends of the stirring blades 405 will drive the inner filter barrel 500 to rise through the limit ring 501. The raised inner filter barrel 500 makes it easy for personnel to extract the pumpkin seeds.
