Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-6 This utility model provides a technical solution for an integrated cleaning and drying device for walnut processing: An integrated cleaning and drying device for walnut processing includes an equipment mounting frame 1, a cleaning tank 2 in the middle of the equipment mounting frame 1, a support plate 3 inside the cleaning tank 2, a water tank 4 on the outside of the equipment mounting frame 1, a water pump 5 and an air pump 9 inside the equipment mounting frame 1, an inlet pipe 6 between the water pump 5 and the water tank 4, an outlet pipe 7 at the output end of the water pump 5, a high-pressure nozzle 8 on the outside of the outlet pipe 7, an air outlet pipe 10 at the output end of the air pump 9, a turbulence nozzle 11 at the bottom of the air outlet pipe 10, a drying component 16 at the upper end of the equipment mounting frame 1, and a mud scraping component 18 at the bottom of the cleaning tank 2.
[0023] The sludge scraping assembly 18 includes an electric push rod 181, the output end of which is provided with a connecting plate 182. A limit switch 183 and a guide rod 184 are provided on one side of the connecting plate 182, and a guide sleeve 185 is provided in the middle of the cleaning tank 2.
[0024] like Figure 1-2 A support frame is provided on one side of the equipment mounting frame 1, and a conveyor frame is installed on the upper end of the support frame. A conveyor motor 12 is provided on the upper end of the conveyor frame. A transmission roller 13 is provided at the output end of the conveyor motor 12. A feeding belt 14 is provided on the outside of the transmission roller 13. Several sets of limiting plates 15 are installed on the outside of the feeding belt 14. The limiting plates 15 and the feeding belt 14 are connected by bolts, which facilitates the conveying of walnuts and makes drying operations convenient.
[0025] like Figure 1 As shown, the equipment mounting frame 1 and the cleaning tank 2 are connected by bolts. The upper end of the bearing plate 3 has several sets of through holes. The water pump 5 is connected to the equipment mounting frame 1 by bolts. The input end of the water pump 5 is connected to the water tank 4 through the water inlet pipe 6. The output end of the water pump 5 is connected to the water outlet pipe 7, which is beneficial for water supply during the walnut cleaning process.
[0026] like Figure 1 and Figure 3As shown, there are several groups of high-pressure nozzles 8 arranged in an array, and each group of high-pressure nozzles 8 is connected to the water outlet pipe 7. The output end of the air pump 9 is connected to the air outlet pipe 10. There are several groups of turbulence nozzles 11 arranged in an array, and the turbulence nozzles 11 are connected to the air outlet pipe 10. A drain outlet 17 is provided on one side of the cleaning tank 2, and a valve is provided on the outside of the drain outlet 17. The turbulence nozzles 11 can effectively enhance the turbulence of the water in the cleaning tank 2 and improve the cleaning effect.
[0027] like Figure 5-6 As shown, the electric push rod 181 is connected to the cleaning tank 2 by bolts. The electric push rod 181 is electrically connected to the external controller. The output end of the electric push rod 181 is fixedly connected to the connecting plate 182. There are two sets of limit switches 183, which are symmetrically distributed. The guide rod 184 is adapted to the guide sleeve 185. A scraper 186 is provided at the bottom of the connecting plate 182. A hinge is provided between the scraper 186 and the connecting plate 182, and the hinge is installed close to the drain outlet 17. A limit block 187 is fixedly connected to one side of the connecting plate 182, which facilitates the scraping of mud at the bottom of the cleaning tank 2.
[0028] like Figure 1 and Figure 4 As shown, the air-drying assembly 16 includes an air-drying rack 161, an air-drying motor 162 is installed at the upper end of the air-drying rack 161, there are two sets of air-drying motors 162 and they are symmetrically distributed, the output end of the air-drying motor 162 is fixedly connected to a fan blade 163, and a heating wire 164 is installed in the middle of the air-drying rack 161, which is conducive to the drying operation of walnuts.
[0029] The working principle of this invention is as follows: During use, the user pours walnuts into the cleaning tank 2. Water is added to the cleaning tank 2 until it reaches the level of the water tank 4. After being filtered inside the water tank 4, the water continuously flows through the inlet pipe 6 into the water pump 5, then into the outlet pipe 7, and finally is sprayed out through the high-pressure nozzle 8. Simultaneously, the air pump 9 sends air through the air outlet pipe 10 into several sets of turbulence nozzles 11, blowing it into the cleaning tank 2, effectively enhancing the cleaning effect within the cleaning tank 2. The increased water agitation enhances the cleaning effect. After cleaning, the walnuts are driven by the output of the conveyor motor 12 to rotate the transmission roller 13, which in turn drives the feeding belt 14 to convey them. This causes the limiting plate 15 to block the walnuts inside the cleaning tank 2, dispersing them. When the walnuts are at the bottom of the drying rack 161, the output of the drying motor 162 drives the fan blades 163 to rotate, and the heating wire 164 is activated to blow hot air straight onto the outer surface of the walnuts, accelerating their drying. This allows the equipment to perform a one-stop cleaning and drying operation, improving the processing efficiency of the walnuts.
[0030] It should be noted that, through the setting of the sludge scraping assembly 18, after the cleaning tank 2 is used and the accumulated sludge inside needs to be cleaned, the output end of the electric push rod 181 can be controlled by the external controller to drive the connecting plate 182 to perform a reset operation. This causes the connecting plate 182 to scrape the sludge at the bottom of the cleaning tank 2 during its movement, bringing the sludge closer to the drain outlet 17. At this time, under the support of the limit block 187, the scraper 186 will not rotate in the opposite direction when performing the sludge scraping operation. During the movement of the connecting plate 182, it slides along the inside of the guide sleeve 185 through the guide rod 184, and the drainage is opened at the same time. The valve on the outside of the drain 17 allows the mud and sand to be discharged through the drain 17. Then, the output end of the electric push rod 181 drives the connecting plate 182 to move. Under the support of the hinge, the scraper 186 is flipped to prevent the remaining mud and sand from being pushed to the other side of the cleaning tank 2. When the limit switch 183 contacts one side of the cleaning tank 2, it feeds back to the controller, which controls the output end of the electric push rod 181 to pull back in the opposite direction. This causes the connecting plate 182 and the scraper 186 to scrape the mud and sand again, thereby treating the mud and sand and preventing the accumulation of mud and sand in the drain 17, thus improving its practicality.
[0031] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
