Technical Field

[0001] This application relates to the technical field of nut cleaning equipment, and in particular to a fully automatic nut cleaning device. Background Art

[0002] During the production and processing of nuts, there are often residues of metal chips, and the nuts need to be cleaned. A nut cleaning device is a device used to clean impurities such as oil stains and iron filings on the surface of nuts.

[0003] The nut cleaning device usually consists of a machine body, a cleaning tank, a spraying system, a feeding component, etc. Usually, the spraying system is used to spray and wash the nuts in the cleaning bin with high-pressure water flow, and the nuts are mechanically stirred by means of the feeding component for multi-faceted washing to remove the dirt on the surface of the nuts. Some devices are also equipped with an ultrasonic vibration system, which generates a cavitation effect through high-frequency vibration to further enhance the cleaning effect.

[0004] At present, after cleaning, the surfaces of some nuts may not be thoroughly cleaned. It is necessary to add a cleaning agent and mix it with the nuts, and the cleaning agent is evenly injected into the drum manually or through a pump. The rotation of the drum is used to promote the mixing of the nuts and the cleaning agent. However, due to the small size and large quantity of the nuts, the mixing may be uneven, which will affect the cleaning effect of the nuts. Summary of the Invention

[0005] In order to improve the cleaning effect of nuts, this application provides a fully automatic nut cleaning device.

[0006] The fully automatic nut cleaning device provided by this application adopts the following technical solution: A fully automatic nut cleaning device includes a cleaning device and a feeding device installed on one side of the cleaning device.

A filter box connected to the feeding device is provided at the discharge port of the mixing device. The mixing device includes a cabinet body, a spiral cylinder, and a driving mechanism. The spiral cylinder is rotatably installed in the cabinet body. The driving mechanism is installed inside the cabinet body and is used to drive the spiral cylinder to rotate. The inner wall of the spiral cylinder is fixedly connected with spiral blades for promoting the mixing of the cleaning liquid and the nuts and pushing the nuts forward. A guide plate connected to the spiral cylinder is fixedly connected to one side of the cabinet body close to the impurity removal device. A pump is fixedly connected to one side of the cabinet body close to the guide plate. One end of the pump is connected to a liquid storage tank connected to the cabinet body, and the other end of the pump is fixedly connected to a movable spray head for guiding the cleaning liquid to spray into the spiral cylinder.

[0007] By adopting the above technical solutions, firstly, through the settings of the cleaning device, feeding device, impurity removal device, mixing device, etc., the full-process automation of nut cleaning can be achieved, reducing manual intervention and improving production efficiency; secondly, the impurity removal device can remove the residues on the surface of the nuts, and the mixing device promotes the mixing of the cleaning liquid and the nuts through the spiral cylinder and spiral blades, ensuring that the nuts can fully contact the cleaning liquid, thereby improving the cleaning effect.

Detailed implementation manners

[0030] The following further elaborates on this application Figure 1-8 in conjunction with the attached drawings.

[0031] An embodiment of this application discloses a fully automatic nut cleaning device.

[0032] Referring to Figure 1 , the cleaning device 1 includes a first cleaning cabinet 11 and a second cleaning cabinet 12. A feeding device 2 is provided on one side of each of the first cleaning cabinet 11 and the second cleaning cabinet 12. The discharge ports of the two feeding devices 2 are respectively located above the feeding ports at the upper ends of the first cleaning cabinet 11 or the second cleaning cabinet 12. The feeding device 2 is used to stably convey nuts into the first cleaning cabinet 11 or the second cleaning cabinet 12 for cleaning. In this application, the feeding device 2 is a conveyor belt lifting feeding device 2, which is a prior art and will not be elaborated here. An impurity removal device 3 is provided at the discharge port of the first cleaning cabinet 11. The impurity removal device 3 cleans the residues such as debris on the nuts after preliminary cleaning by vibration; a mixing device 4 for mixing the cleaning agent and the nuts is provided at the discharge port of the impurity removal device 3. A filter box 5 is provided below the discharge port of the mixing device 4, and the lower end of the other feeding device 2 is fixedly connected to one side of the filter box 5 for guiding the nuts in the filter box 5 into the second cleaning cabinet 12 for secondary cleaning. A vibration device 7 for removing the water stains on the surface of the nuts is provided at the discharge port of the second cleaning cabinet 12, and then it falls from the discharge port of the vibration device 7 into the collection tank 8 for unified collection and processing. In this application, the structure of the vibration device 7 is the same as that of the impurity removal device 3, but the purposes are different.

[0033] Referring to Figure 1 , Figure 2 and Figure 6, the impurity removal device 3 and the vibration device 7 are interconnected devices, both of which include a fixed frame 31, four damping rods 34 fixedly installed at the upper four corners of the fixed frame 31, and a vibrating disk 32 fixedly connected to the upper ends of the piston rods of the four damping rods 34. Vibration springs 35 are sleeved on the outer sides of the damping rods 34 and are fixedly connected between the fixed frame 31 and the vibrating disk 32. The vibration springs 35 are used to provide elastic support for the vibrating disk 32, and in cooperation with the damping rods 34, the vibrating disk 32 is allowed to vibrate within a certain range, thereby extending the service life of the device and improving its operating stability. A vibration motor 33 for driving the vibrating disk 32 to vibrate is fixedly connected to the lower side of the vibrating disk 32. A plurality of grid-shaped holes are formed in the upper end of the vibrating disk 32, and the diameters of these holes are smaller than the diameter and width of the nut, preventing the nut from falling out of these holes and enabling the debris or liquid remaining on the nut to fall through these holes. Protective plates are fixedly connected to the upper edges of the vibrating disk 32 to prevent the nut from falling due to vibration. A conical sewage outlet 36 is provided at the lower end of the vibrating disk 32, so that the shaken-off debris or liquid is discharged from the conical sewage outlet 36 for convenient unified collection and treatment.

[0034] Refer to Figure 2 , Figure 3 , the mixing device 4 includes a cabinet body 41 and a spiral cylinder 42 rotatably installed inside the cabinet body 41. A spiral blade 421 is fixed to the inner wall of the spiral cylinder 42. When the spiral cylinder 42 rotates, the nut is pushed forward by means of the spiral blade 421, and the uniformity of the mixing of the nut and the cleaning agent can be promoted. In this application, the shape of the spiral cylinder 42 is a hollow roller formed by splicing a cylindrical shape at both ends and an elliptical shape in the middle. The pitch of the spiral blade 421 at both ends and located on the inner wall of the cylindrical part of the spiral cylinder 42 is 10 cm to 15 cm, which can increase the forward distance of the nut and improve the conveying speed of the nut. The pitch of the middle spiral blade 421 is 5 cm to 10 cm, which can reduce the forward distance of the nut and enable the nut to stay in the spiral cylinder 42 for a longer time, thereby ensuring the full mixing of the nut and the cleaning agent.

[0035] Refer to Figure 2 , Figure 3, a travel switch 45 is fixedly connected to one side of the material guide plate 44, and a pump 46 electrically connected to the travel switch 45 is fixedly connected to one inner wall of the cabinet body 41. A liquid storage tank 47 connected to the water inlet of the pump 46 is installed outside the cabinet body 41. A circulation pipeline 471 is fixedly connected to one side of the liquid storage tank 47. One end of the circulation pipeline 471 is fixedly connected to a collection box 6. The collection box 6 is arranged below the filter box 5 and is used to collect the cleaning agent dripping from the through holes of the filter box 5, and then flows into the liquid storage tank 47 through the circulation pipeline 471 to complete the recycling of the cleaning agent and reduce the consumption of the cleaning agent. One end of the discharge port of the pump 46 is fixedly connected to a movable spray head 461. The movable spray head 461 is used to spray the cleaning agent into the spiral cylinder 42 for mixing with the nuts. The contact of the travel switch 45 is arranged on one upper side of the baffle 441. When the baffle 441 rotates, it can contact the contact of the travel switch 45, thereby controlling the travel switch 45 to send an instruction to the pump 46, so that the pump 46 operates to spray the cleaning agent into the spiral cylinder 42 through the movable spray head 461. When the baffle 441 is in the closed state and does not contact the contact of the travel switch 45, the pump 46 will not operate.

[0036] Reference Figure 2 , Figure 7 and Figure 8 , the first cleaning cabinet 11 and the second cleaning cabinet 12 both include a machine body 13, a filter cylinder 14 fixedly installed inside the machine body 13, and a stirring blade 15 rotatably connected inside the filter cylinder 14. The feed inlet of the filter cylinder 14 is fixedly connected to the upper end of the machine body 13 and is located directly below the discharge port of the feeding device 2, which is used to ensure that the nuts can stably enter the filter cylinder 14. A drive box 16 for driving the stirring blade 15 to rotate is installed on one side of the machine body 13. Inside the drive box 16, there are a motor, gears, chains, and a transmission rod. The transmission rod is fixedly connected to one end of the stirring blade 15, and this driving method is a prior art and will not be elaborated here. The drive box 16 is used to drive the stirring blade 15 to rotate back and forth inside the filter cylinder and complete the flipping of the nuts through the stirring blade to improve the cleaning effect. A through port 141 communicating with the discharge port of the machine body 13 is opened on one side of the filter cylinder 14. When the stirring blade 15 rotates, it can push some of the cleaned nuts out through the through port 141 and slide onto the upper side of the vibrating plate 32 through the discharge port of the machine body 13.

[0037] Reference Figure 2 , Figure 7 and Figure 8, on one side of the body 13, a spray pipe 17 is fixedly connected, with one end passing through the inner wall of the filter cartridge 14. A plurality of high-pressure nozzles arranged in an array are fixedly connected to the lower side of the spray pipe 17, which are used to clean the oil stains and impurities on the surface of the nuts, etc. On one side of each of the first cleaning cabinet 11 and the second cleaning cabinet 12, a circulating water tank 18 is fixedly connected. At the upper ends of the two circulating water tanks 18, a high-pressure pump 19 fixedly connected to one end of the spray pipe 17 is respectively provided. The high-pressure pump 19 is used to pump the water inside the circulating water tank 18, increasing the pressure and flow rate of the water jet, thereby enhancing the cleaning effect on the nuts. And the lower end of the circulating water tank 18 communicates with the lower end of the body 13, enabling the water for cleaning the nuts to be recycled and reducing the consumption of water resources.

[0038] Refer to Figure 3 , Figure 5 , a driving mechanism 43 is fixedly connected to the inner wall of the cabinet body 41. The driving mechanism 43 is used to drive the spiral cylinder 42 to rotate stably within the cabinet body 41, thereby completing the transportation and mixing of the nuts. In this application, the driving mechanism 43 is composed of a motor, a transmission gear, a toothed ring, rollers, and a positioning ring. This driving mechanism 43 is a prior art, so it will not be elaborated here in detail.

[0039] Refer to Figure 3 , Figure 4 and Figure 5 , at one end of the cabinet body 41 close to the impurity removal device 3, a guide plate 44 for guiding the nuts to slide into the interior of the spiral cylinder 42 is fixedly connected. One end of the discharge port of the impurity removal device 3 extends into the inner side of the guide plate 44 to ensure that the nuts can stably fall onto the guide plate 44. One end of the spiral cylinder 42 is rotatably connected to the inner side of the guide plate 44, preventing the nuts from falling when sliding into the interior of the spiral cylinder 42. A baffle 441 for controlling the conveying amount of the nuts is hinged to one side of the guide plate 44, which is used to reduce the accumulation of nuts during transportation, thereby ensuring the stability of nut transportation. An elastic pad 442 is fixedly connected to one side of the baffle 441. The elastic pad 442 is used to reduce the collision between the nuts and the baffle 441, improving the service life of the baffle 441. The lower ends of the elastic pad 442 and the baffle 441 are both arc-shaped, which can reduce the damage to the nuts and prevent the nuts from being scratched when passing through the lower end of the baffle 441, thereby ensuring the quality of the nuts.

[0040] The implementation principle of the full-automatic nut cleaning device in the embodiments of this application is as follows: When in use, in the first step, the first feeding device 2 is used to convey the freshly produced nuts into the filter cartridge 14 inside the first cleaning cabinet 11. The high-pressure pump 19 is started to extract the water inside the circulating water tank 18, and it is sprayed out by the high-pressure nozzles of the spray pipe 17 to preliminarily clean these nuts. In the second step, the drive box 16 inside the first cleaning cabinet 11 is started to drive the stirring blades 15 to rotate, driving the cleaned nuts to move to the through port 141 and slide down from the discharge port of the machine body 13 onto the vibrating disk 32. In the third step, the vibration motor 33 is started to drive the vibrating disk 32 to vibrate along the upper sides of the damping rod 34 and the vibration spring 35, capable of vibrating and cleaning the impurities or liquid remaining on the surface of the nuts. In the fourth step, the nuts after the vibration treatment slide into the spiral cylinder 42 of the mixing device 4 through the guide plate 44. During the sliding process on the guide plate 44, the nuts will push the lower end of the baffle 441 to rotate. At this time, the upper end of the baffle 441 will contact the contact of the travel switch 45, controlling the operation of the pump 46, so that the cleaning agent can be sprayed into the spiral cylinder 42 by the movable nozzle 461 to be mixed with the nuts. In the fifth step, the drive mechanism 43 inside the cabinet body 41 is started to drive the spiral cylinder 42 to rotate. With the help of the spiral blades 421 inside the spiral cylinder 42, the nuts and the cleaning agent are pushed forward. And the nuts will roll during the forward movement, fully mixing with the cleaning agent until the nuts are discharged from the other end of the spiral cylinder 42 and fall into the filter box 5. In the sixth step, the second feeding device 2 is started to convey the nuts inside the filter box 5 into the second cleaning cabinet 12, repeating the above operations to complete the secondary cleaning of the nuts and convey them onto the vibration device 7. Finally, the vibration device 7 is started to remove the liquid on the surface of the nuts, and then the nuts fall into the collection box 8 to complete the cleaning work of the nuts.

[0041] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
