Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning devices, and particularly relates to a watermelon seed cleaning device. Background Art

[0002] When watermelon seeds are just separated from the watermelon pulp, a large amount of mucus and sugar will be carried on their surfaces. If these mucus and sugar are not cleaned, after the watermelon seeds germinate, their surfaces will easily adhere together. When separating the germinated seeds for subculture later, it is necessary to separate them, which is time-consuming and laborious. Therefore, when watermelon seeds are separated from the watermelon pulp, they generally need to be cleaned.

[0003] Most of the existing watermelon seed cleaning devices rely on stirring blades (such as the patent document with the publication number CN206868711U) to clean them. However, the epidermis of watermelon seeds just separated from the watermelon pulp is relatively tender. When the stirring blades stir, it will cause varying degrees of damage to the epidermis of the watermelon seeds. In severe cases, it will even scratch the epidermis of the watermelon seeds, resulting in the inactivation of the watermelon seeds and affecting the germination rate of the watermelon seeds. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a watermelon seed cleaning device to solve the technical problem in the above background art that it is easy to damage the epidermis of watermelon seeds, resulting in the inactivation of watermelon seeds and affecting the germination rate of watermelon seeds.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A watermelon seed cleaning device includes: a fixed plate, a moving plate, and an up-and-down cylinder; the fixed plate is a plate-like structure, and several vertical up-and-down cylinders are fixed below the fixed plate. The telescopic end of the up-and-down cylinder is fixed with a plate-like moving plate below. A group of clamping cylinders are fixed on both sides of the moving plate by clamping frames respectively. The end of the telescopic rod of the clamping cylinder is fixed with a clamping block. The vibration washing disc is a square box structure, and an outward convex clamping edge is provided at its upper edge. A clamping groove for inlaying the clamping edge is provided on the clamping block. An externally embedded block in the shape of a block is externally embedded and fixed on the telescopic rod of each group of clamping cylinders, and a vibration motor is fixed below the externally embedded block.

[0007] Furthermore: In order to add cleaning water and cleaning agent into the vibration washing disc before vibration washing, a first electric pump and a second electric pump are fixed on the fixed plate. The liquid outlets of the first electric pump and the second electric pump are located directly above the moving plate. A hole for the liquid outlets of the first electric pump and the second electric pump to pass through is opened in the middle of the moving plate; the liquid inlet of the first electric pump is connected with a water pipe, and the liquid inlet of the second electric pump is connected with a trisodium phosphate solvent pipe.

[0008] Further: In order to facilitate the transfer of the vibration washing tray before and after vibration washing, a conveyor is provided directly below the fixed plate, and the width of the conveyor is greater than the width of the vibration washing tray.

[0009] Further: In order to make the transportation between the fixed plate and the moving plate more stable, a stabilizing mechanism is provided between the fixed plate and the moving plate. The stabilizing mechanism includes: sliding columns, connecting frames, and sliding seats; a vertical sliding column is fixedly installed directly above each of the four corners of the moving plate on the lower surface of the fixed plate, and a sliding seat is slidably fitted on each group of sliding columns. Each group of sliding seats is fixed to the upper surface of the moving plate by a connecting frame.

[0010] Further: In order to reduce the influence of the vibration motor on the clamping cylinder, a buffer column made of an elastic material is provided on the telescopic rod on the side of the outer embedded block close to the clamping cylinder.

[0011] Further: In order to be able to fix the fixed plate conveniently, a plurality of mounting holes for installation are provided on the fixed plate.

[0012] Further: In order to avoid splashing water residue during vibration washing, the conveyor used is a roller conveyor.

[0013] Further: In order to increase the rubbing effect between the watermelon seeds and the vibration washing tray, convex lines are provided on the bottom or side of the vibration washing tray to form convex patterns.

[0014] In summary, the present utility model has the following beneficial effects:

[0015] ① It does not rely on stirring blades for cleaning, and can greatly reduce the damage to the epidermis of watermelon seeds: By setting up the vibration motor, the upper and lower cylinders drive the moving plate, the clamping frame, the clamping cylinder and the clamped vibration washing tray to rise until the bottom of the vibration washing tray is separated from the conveyor. At this time, the first electric pump and the second electric pump are started to inject a certain amount of cleaning water and trisodium phosphate solvent downward respectively. Then, the two groups of vibration motors are started to work. The vibration of the vibration motor is transmitted to the vibration washing tray through the telescopic rod and the clamping block. Under the action of vibration, relative friction occurs between the watermelon seeds and between the watermelon seeds and the convex patterns on the vibration washing tray to form vibration washing, thereby removing the mucus and sugar on the surface of the watermelon seeds. At the same time, the trisodium phosphate solvent releases highly concentrated alkaline phosphate ions, which can combine with the carboxyl groups to form water-soluble soap molecules; due to the strong hydrophilicity of these soap molecules, they can be fully mixed with water molecules, thus more effectively removing mucus and sugar.

[0025] In order to add cleaning water and cleaning agent to the vibrating washing plate 8 before vibrating washing, a first electric pump 4 and a second electric pump 5 are fixed on the fixed plate 1. The liquid outlets of the first electric pump 4 and the second electric pump 5 are located directly above the moving plate 2.

[0026] In order to facilitate the transfer of the vibrating washing plate 8 before and after vibrating washing, a conveyor 12 is provided directly below the fixed plate 1, and the width of the conveyor 12 is greater than the width of the vibrating washing plate 8.

[0027] To make the transportation between the fixed plate 1 and the moving plate 2 more stable, a stabilizing mechanism 9 is provided between the fixed plate 1 and the moving plate 2. The stabilizing mechanism 9 includes: a sliding column 91, a connecting frame 92, and a sliding seat 93. A vertical sliding column 91 is fixedly installed above each of the four corners of the moving plate 2 on the lower surface of the fixed plate 1. A sliding seat 93 is slidably engaged with each group of sliding columns 91, and each group of sliding seats 93 is fixed to the upper surface of the moving plate 2 by a connecting frame 92.

[0028] To reduce the influence of the vibration motor 11 on the clamping cylinder 7, a buffer column 73 made of an elastic material is provided on the telescopic rod 71 on the side of the outer embedded block 72 close to the clamping cylinder 7.

[0029] To facilitate the fixing of the fixed plate 1, a plurality of groups of mounting holes 13 for installation are provided on the fixed plate 1.

[0030] To avoid splashing water residue during vibration washing, the conveyor 12 used is a roller conveyor.

[0031] To increase the rubbing effect between the watermelon seeds and the vibration washing plate, convex lines 82 are provided on the bottom or side of the vibration washing plate 8 to form convex patterns.

[0032] Brief description of the usage process:

[0033] During use, first, an external control mechanism is connected to the upper and lower cylinders 3, the first electric pump 4, the second electric pump 5, the clamping cylinder 7, and the vibration motor 11. A water pipe 41 is connected to a water storage tank, and a trisodium phosphate solvent pipe 51 is connected to a trisodium phosphate solvent storage tank.

[0034] Then, the watermelon seeds to be cleaned are poured into the vibration washing plate 8, and multiple vibration washing plates 8 filled with watermelon seeds are placed on the conveyor 12 for transportation by the conveyor 12. When the vibration washing plate 8 filled with watermelon seeds is transported by the conveyor 12 below the fixed plate 1, the conveyor 12 pauses, and then the upper and lower cylinders 3 are driven to extend. The upper and lower cylinders 3 drive the moving plate 2 to move downward, and thus all the clamping cylinders 7 and the clamping blocks 10 fixed to the moving plate 2 by the clamping frame 6 move downward accordingly.

[0035] When the clamping groove on the clamping block 10 moves to the same height as the clamping edge 81 on the edge of the vibration washing plate 8, at this time, the telescopic rods 71 on the two groups of clamping cylinders 7 are controlled to extend, and the clamping blocks 10 at the ends of the telescopic rods 71 perform a clamping operation on the vibration washing plate 8. At this time, the clamping groove of the clamping block 10 externally clamps the clamping edge 81 of the vibration washing plate 8.

[0036] Then drive the upper and lower cylinders 3 to shorten. The upper and lower cylinders 3 drive the moving plate 2, the clamping frame 6, the clamping cylinder 7, and the clamped vibrating washing plate 8 to rise accordingly until the bottom of the vibrating washing plate 8 is separated from the conveyor 12. At this time, start the first electric pump 4 and the second electric pump 5 to inject a certain amount of cleaning water and trisodium phosphate solvent downward respectively. Then start the two groups of vibrating motors 11 to work. The vibration of the vibrating motors 11 is transmitted to the vibrating washing plate 8 through the telescopic rod 71 and the clamping block 10. Under the action of vibration, relative friction occurs between the watermelon seeds and between the watermelon seeds and the convex stripes 82 of the vibrating washing plate 8 to form vibrating washing, thereby removing the mucus and sugar on the surface of the watermelon seeds. At the same time, the trisodium phosphate solvent releases highly concentrated alkaline phosphate ions, which can combine with the carboxyl groups to form water-soluble soap molecules; due to the strong hydrophilicity of these soap molecules, they can be fully mixed with water molecules, thus more effectively removing mucus and sugar;

[0037] After vibrating and washing for a period of time, drive the upper and lower cylinders 3 to extend. The upper and lower cylinders 3 drive the moving plate 2 to move downward, and then all the clamping cylinders 7 and the clamping block 10 fixed on the moving plate 2 through the clamping frame 6 and the vibrating washing plate 8 move downward accordingly, and then place the vibrating washing plate 8 back on the conveyor 12. Then drive the clamping cylinder 7 to shorten, and the clamping block 10 at the end of the clamping cylinder 7 releases the clamping of the vibrating washing plate 8. The conveyor 12 transports the washed watermelon seeds and the vibrating washing plate 8 they are on to the next draining process, and transports the next group of watermelon seeds to be vibrated and washed and the vibrating washing plate 8 they are on to the lower part of the fixing plate 1 to wait for cleaning. In this way, batch vibratory washing operations of watermelon seeds are realized by repeating the process.

[0038] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
