[0002] Due to the growth environment and picking methods of red dates, there will be debris such as branches and leaves mixed in after the red dates are picked, and dust will adhere to the surface of the red dates. Therefore, in the subsequent processing of red date foods, it is necessary to carry out impurity removal and cleaning processes. In conventional processes, the red dates are mostly directly poured into water and washed by stirring, rolling and other means to remove dust attached to the surface. However, relying solely on flushing means, due to the presence of branch and leaf debris, more water will be required for flushing to avoid ineffective separation.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 As shown, in Example 1, a red date impurity removal and cleaning machine comprises a frame 1, a hopper 2 is provided on the top of the frame 1, and the hopper can hold the red dates to be cleaned and cleaned, and a pulsator unloading mechanism 3 is provided at the unloading port of the hopper 2, and the pulsator unloading mechanism can unload the red dates in the hopper 2 evenly and continuously, so that the unloading speed of the red dates can be controlled. The lower end of the unloading port of the hopper 2 is connected to the impurity blowing bin 4, and the impurity blowing bin 4 is provided with a blowing assembly, and the lower end of the impurity blowing bin 4 corresponds to the ultrasonic cleaning tank 5. Due to the large difference in quality between red dates and impurities, the blowing assembly can blow and separate the red dates and impurities passing through the impurity blowing bin during the unloading process, and the red dates and impurities are separated by air flow, and a material frame 6 is slidably provided in the ultrasonic cleaning tank 5. The red dates after impurity removal and separation fall into the material frame located in the ultrasonic cleaning tank, and then the ultrasonic cleaning tank performs ultrasonic decontamination cleaning on the dust on the surface of the red dates. The device has a simple structure and is convenient for feeding. In addition, the impeller feeding mechanism is used to gradually and continuously feed the red dates to avoid impurities being entrapped. At the same time, the impurity removal effect is better by blowing. Finally, ultrasonic cleaning is used to make the cleaning more thorough.

[0020] Embodiment 2, as Figure 2 As shown, the red date impurity removal and cleaning machine is based on the embodiment 1, and the impeller unloading mechanism 3 includes a roller shaft 7 rotatably arranged on the frame 1, and the roller shaft 7 is provided with a plurality of grooves in the circumference, and the frame 1 is provided with a driving motor 8 for driving the roller shaft 7 to rotate. In this embodiment, the groove is a full-body arc groove 9 opened on the roller shaft 7. The full-body arc groove runs through the roller shaft in the length direction, so that the red dates can enter the groove in rows, and at the same time, the whole row is released as the roller shaft rotates. At the same time, the unloading method of this embodiment can avoid the problem of impurities being entrained and difficult to separate caused by the large instantaneous unloading amount.

[0021] When it is necessary to discharge the red dates, the driving motor drives the roller to rotate, so that the arc groove on the roller moves with it, thereby transferring the red dates entering the arc groove from the upper hopper to the impurity blowing and separation bin below.

[0022] In addition, in this embodiment, the gap between the shell and the roller at the discharge port of the hopper is smaller than the diameter of the red dates, so that the red dates can only be transferred to the bottom through the groove, preventing the red dates in the hopper from falling naturally from the gap.

[0023] Embodiment 3, a red date impurity removal and cleaning machine, based on embodiment 2, the impurity blowing and separation bin 4 includes a bin body 10 fixedly mounted on the frame 1, and the top and bottom of the bin body 10 are provided with openings corresponding to the impeller unloading mechanism 3 and the ultrasonic cleaning tank 5, respectively. In this embodiment, the top opening of the bin body is connected to the unloading port of the hopper, and corresponds to the roller 4 of the impeller unloading mechanism 3, so that the red dates carried by the roller 4 can enter the bin body when they fall.

[0024] In addition, the blowing and separating assembly includes a grid plate 11 vertically arranged in the silo 10, a fan 12 is arranged on the silo 10 on one side of the grid plate 11, an air inlet for satisfying the air intake of the fan is arranged on the silo 10, and a debris discharge port 13 corresponding to the grid plate 11 is arranged on the silo 10 on the other side. In this embodiment, the grid plate is located on one side of the top opening of the silo, and the red dates fall into the silo and pass through the fan and the grid plate. The wind of the fan is used to blow the impurities in the red dates through the grid plate and discharge the impurities from the silo through the debris discharge port. In this embodiment, a storage frame 14 corresponding to the debris discharge port 13 is arranged on one side of the frame 1, and when the impurities are blown out of the debris discharge port, they fall into the storage frame. The grid plate is arranged to intercept the red dates when they are blown and moved at the same time, so as to prevent them from being blown out with the impurities. Under the action of gravity, the red dates move down along the surface of the grid plate until they fall into the material frame below through the outlet. In this embodiment, the grid holes of the grid plate are arranged vertically, which is conducive to the red dates sliding down along the surface of the grid plate after being blown to the surface of the grid plate.

[0025] Embodiment 4, a red date impurity removing and cleaning machine, is based on Embodiment 3, wherein the ultrasonic cleaning tank 5 comprises a water tank 15, which is a long cubic water tank with an open top, and an ultrasonic emitter 16 is arranged at the center position on the bottom or side wall of the water tank 15.

[0026] In this embodiment, the material frame 6 is a rectangular mesh frame with an opening at the top, and the length of the rectangular mesh frame is less than the length of the water tank. In this embodiment, the water tank is fixed on the ground or on a rack, and the length of the water tank is greater than the length of two rectangular mesh frames, which can store more clean water, have a better cleaning effect, and can be used multiple times. A handle is provided at the upper end of the rectangular mesh frame, and a roller is provided at the bottom. During the unloading process, the rectangular mesh frame is pushed to move to one end of the water tank, so as to correspond to the lower end opening of the warehouse body, so that the red dates fall into the rectangular mesh frame. After the unloading is completed, the handle is pulled to move the rectangular mesh frame to correspond to the ultrasonic transmitter. At the same time, the material frame 6 is made of plastic material to facilitate ultrasonic penetration. In this embodiment, the ultrasonic transmitter 16 is arranged at the center of the side wall of the water tank 15, and the two ends of the rectangular mesh frame along the length direction of the water tank 15 are provided with a shielding net 17. When the rectangular mesh frame moves to correspond to the ultrasonic transmitter, the ultrasonic transmitter emits ultrasonic waves, generates ultrasonic vibrations to the water body in the rectangular mesh frame, and thus cleans the red dates in the rectangular mesh frame. As a further optional method, the water tank 15 is provided with a middle cover 18 that can be opened and closed. The middle cover is also located in the middle position corresponding to the ultrasonic cleaner. The size of the middle cover is consistent with the rectangular mesh frame. When ultrasonic cleaning is performed, the middle cover is used to cover the top of the rectangular mesh frame, thereby simultaneously utilizing the shielding effect generated by the shielding net and the middle cover to reduce the leakage of ultrasonic waves. After ultrasonic treatment for a period of time, continue to pull the handle to move the material frame, move the material frame to the other end, and finally take the material frame out of the water tank for unloading. After unloading is completed, put the material frame back into the water tank corresponding to the lower end of the warehouse body. In this embodiment, a drain pipe 19 is provided at one end of the water tank 15, and a water inlet pipe 20 is provided at the other end. Valves are provided on the drain pipe 19 and the water inlet pipe. The water inlet pipe is connected to the tap water pipe, so that the water in the water tank is replaced by the drain pipe and the water inlet pipe.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
