Description

Technical Field

[0001] The utility model relates to a watermelon seed stirring and cleaning device. Background Art

[0002] Before the watermelon seeds are stewed in sauce, they need to be cleaned to remove the mucous membrane, dust, weeds, etc. on the surface of the watermelon seeds. The current cleaning method is to first lift the cleaning basket into the cleaning tank, and then the single-arm crane puts the stirrer into the cleaning basket. After fixing the motor connected to the stirrer, watermelon seeds are put into the cleaning basket for cleaning and stirring. After the cleaning is completed, the single-arm crane lifts out the stirrer to make room for the overhead crane to lift. Then the overhead crane lifts the cleaning basket out of the cleaning tank, drains the water of the watermelon seeds, and then puts the watermelon seeds into the stewing pot to be stewed in sauce. This cleaning method requires lifting the cleaning basket and the stirrer in and out, which affects the cleaning efficiency. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment 1:

[0018] As Figure 1 shown, a watermelon seed stirring and cleaning device includes a cleaning barrel 3 fixedly arranged on a platform 16. The bottom of the cleaning barrel 3 is communicated with a discharge pipe 15 and a drain pipe 10. The upper end of the discharge pipe 15 is connected to a cleaning basket 4 arranged in the cleaning barrel 3. A discharge valve 11 is installed at the bottom of the discharge pipe 15. A stirring shaft 8 is arranged in the cleaning basket 4, and a stirring paddle 7 is fixedly connected to the stirring shaft 8. The upper end of the stirring shaft 8 is in transmission connection with a reduction motor 1 fixedly connected to a bracket.

[0019] The working process of this utility model is as follows: The staff stands on the platform 16, opens the gate valve 17 on the discharge pipe 18 at the lower end of the watermelon seed bin, and allows the watermelon seeds to enter the cleaning basket 4 along the discharge pipe 18. After the watermelon seeds are discharged, the gate valve 17 on the discharge pipe 18 is closed. Then, tap water and edible alkali solution are put into the cleaning bucket 3. After the cleaning bucket 3 is filled with water, the reduction motor 1 is started, and the stirring paddle 7 is driven by the reduction motor 1 to rotate to clean the watermelon seeds. After the watermelon seeds are cleaned, the valve on the drain pipe 10 is opened to drain all the water in the cleaning bucket 3. Finally, the discharge valve 11 at the lower end of the discharge pipe 15 is opened, and the watermelon seeds flow into the hanging basket 14 along the discharge pipe 15, thus completing the cleaning process of the watermelon seeds.

[0020] A weighing sensor 6 is provided between the cleaning bucket 3 and the platform 16, and the weighing sensor 6 is connected to the weighing display 5. When the staff puts watermelon seeds into the cleaning basket 4, the input amount of watermelon seeds can be observed in real time through the weighing display 5 to ensure that the weight, cleaning time, and addition amount of edible alkali of the watermelon seeds for each cleaning are the same, so that the cleaning standards are the same and the cleaning quality is guaranteed.

[0021] A spiral blade 9 is provided in the discharge pipe 15, and the spiral blade 9 is fixedly connected to the stirring shaft 8. When cleaning the watermelon seeds, the reduction motor 1 drives the spiral blade 9 to rotate in the discharge pipe 15 through the stirring shaft 8. During the rotation of the spiral blade 9, the watermelon seeds in the discharge pipe 15 are driven to move upward, so that they participate in the stirring of the watermelon seeds, avoiding dead corners and ensuring the cleaning quality.

[0022] A track 13 is provided on the ground below the cleaning bucket 3, and a trolley 12 is provided on the track 13. A hanging basket 14 is placed on the trolley 12. Usually, multiple cleaning buckets 3 are arranged on one platform 16, and the track 13 is arranged below each cleaning bucket 3. After the watermelon seeds in one of the cleaning buckets 3 are cleaned, the trolley 12 moves below the cleaning bucket 3, and then the discharge valve 11 below the cleaning bucket 3 is opened to allow the watermelon seeds to pour into the hanging basket 14 for draining. Then, the trolley 12 drags the hanging basket 14 out from below the platform 16, and the crane pours the watermelon seeds in the hanging basket 14 into the brine pot for brining. In this way, only one hanging basket 14 is needed to complete the transfer process of the watermelon seeds in all the cleaning buckets 3, and during the transfer process, the crane is not occupied for a long time, which does not affect the cleaning of the cleaning device.

[0023] Embodiment 2:

[0024] As Figure 2 and 3As shown in the figure, Embodiment 2 is a further improvement made on the basis of Embodiment 1. The discharge valve 11 is a pneumatic discharge valve 11, and the gate valve 17 is a pneumatic gate valve 17. A first electric valve 19, a second electric valve 21, and a third electric valve 22 are respectively installed on the water pipe 2, the lye pipe 20 for transporting the edible alkali solution, and the drain pipe 10. The first electric valve 19, the second electric valve 21, the third electric valve 22, the reduction motor 1, and the solenoid valves for controlling the pneumatic discharge valve 11 and the gate valve 17 are controlled to open and close by the PLC controller. The weighing sensor 6 transmits the detected data to the PLC controller.

[0025] During implementation, the controller first controls the pneumatic gate valve 17 to open, allowing the watermelon seeds to automatically fall into the cleaning basket 4. At the same time, the weighing sensor 6 weighs them. After the weight reaches the first set weight, the feeding of watermelon seeds stops. Then the controller opens the first electric valve 19, and tap water enters the cleaning barrel 3. After the weight reaches the second set weight, the first electric valve 19 closes to stop the water supply. Then the controller controls the second electric valve 21 to open, and the edible alkali solution flows into the cleaning barrel 3. After the weight reaches the third set weight, the second electric valve 21 closes. Then the controller controls the reduction motor 1 to start and clean the watermelon seeds. After the cleaning time is up, the third electric valve 22 is opened to drain the water in the cleaning barrel 3. Then the controller controls the third electric valve 22 to close, and tap water is poured into the cleaning barrel 3 again for rinsing. After the rinsing is completed, the controller controls the pneumatic discharge valve 17 to open to discharge the watermelon seeds, thus completing the full-automatic cleaning process of the watermelon seeds, which reduces the labor intensity of workers and improves the cleaning efficiency.

[0026] The content described in the embodiments of this specification is only a list of the implementation forms of the utility model concept. The protection scope of the present utility model should not be regarded as limited to the specific forms stated in the embodiments. The protection scope of the present utility model also extends to equivalent technical means that those skilled in the art can think of according to the utility model concept.
