[0007] The aforementioned linear potato washing and screening device includes a support mechanism comprising a frame base mounted on the frame and the frame body, a swing arm hinged to one side of the frame base, and a connecting seat at the other end of the swing arm for floating and limiting.

[0008] In the aforementioned linear potato washing and screening device, both the frame and the connecting seat are equipped with elastic rubber pads that abut against the swing arm.

[0009] In the aforementioned linear potato washing and screening device, there are multiple support mechanisms, which are evenly distributed around the frame.

[0010] In the aforementioned linear potato washing and screening device, the water pipe is connected to the frame via a pipe clamp.

[0011] In the aforementioned linear potato washing and screening device, the discharge area of ​​the frame is equipped with a guide plate for diverting the washing wastewater back to the water tank.

[0012] In the aforementioned linear potato washing and screening device, the driving mechanism is a vibrating motor.

[0013] The aforementioned linear potato washing and screening device also includes a cover on the upper part of the frame for covering the nozzles.

[0028] This invention provides a linear potato washing and screening device for efficiently, water-savingly, and with low damage to clean potatoes. Figure 1-7 As shown, the device includes a frame 1, and a frame 2 is mounted on the upper part of the frame 1 via a support mechanism 3. The two ends of the frame 2 are defined as the potato feeding area and the potato discharging area, respectively, and the potatoes form a clear movement path as they move from the feeding area to the discharging area.

[0029] A drive mechanism 4 is arranged at one end of the feeding area of ​​the frame 2. The drive mechanism 4 is preferably a vibrating motor. When the vibrating motor is working, it drives the frame 2 to vibrate, thereby causing the potatoes on the frame 2 to move along the movement path towards the discharge area, and generating a continuous tumbling motion in the process.

[0030] Along the movement path of the potatoes, a spraying mechanism 5 and a water blowing mechanism 6 are arranged in sequence. The spraying mechanism 5 is responsible for rinsing the potatoes as they roll, while the water blowing mechanism 6 is responsible for blowing off any residual water on the surface of the potatoes.

[0031] Specifically, the spraying mechanism 5 includes a water pipe 51 arranged on the upper part of the frame 2 but not in direct contact with the frame 2. Multiple nozzles 52 are installed at intervals on the water pipe 51, all facing the potato movement path inside the frame 2. A water tank 53 is provided below the frame 1 to store washing water. The water pipe 51 is connected to the water tank 53 via a water pump 54, thereby pumping water from the water tank 53 into the water pipe 51 and spraying it out through the nozzles 52. The water pipe 51 can be connected and fixed to the frame 1 using fasteners such as pipe clamps.

[0032] The drying mechanism 6 includes a housing 61 fixed to the upper part of the frame 2 and connected to the frame body 1. A ventilation grille 62 is provided below the housing 61, and a blower is connected to one side of the housing 61. The airflow generated by the blower enters the housing 61 and is evenly blown onto the potatoes passing below through the ventilation grille 62 to achieve a drying effect.

[0033] Inside the frame 2, a sieve plate 21 is laid along the movement path of the potatoes. This sieve plate 21 is used to separate the potatoes from the wastewater and mud generated during rinsing. The sieve plate 21 is detachably connected to the frame 2 on all four sides for easy daily cleaning and maintenance.

[0034] The specific structure of the support mechanism 3 is as follows: It includes brackets 31 fixedly installed on the upper part of the frame 2 and the frame body 1 respectively. These brackets 31 are arranged parallel and spaced apart, forming a gap that allows the frame 2 to move. On one side of each bracket 31, a swing arm 32 with one end rotatable around it is hinged, and the other end of the swing arm 32 is equipped with a connecting seat 33 for floating limit. In order to provide cushioning and elastic restoring force, elastic rubber pads 34 are arranged at intervals around the inside of the brackets 31 and the connecting seat 33. These elastic rubber pads 34 always maintain contact with the swing arm 32. In order to ensure the stability of the frame 2 vibration, the number of support mechanisms 3 is set to multiple and evenly distributed around the frame 2.

[0035] To recycle water resources, a guide plate 22 is installed in the discharge area of ​​the frame 2. The guide plate 22 can guide the wastewater washed off the surface of the potatoes and make it flow back into the water tank 53 located at the bottom of the frame 1, so as to realize the recycling of water resources.

[0036] In addition, to protect the nozzle 52 and optimize the appearance of the equipment, an additional cover 61 for the nozzle 52 can be installed on the upper part of the frame 2.

[0037] How to use The method of using this utility model of linear potato washing and screening device is as follows: 1. Preparation: Before starting the device, ensure that the water tank 53 contains sufficient water. Start the vibration motor, water pump 54, and blower.

[0038] 2. Feeding and Washing: Potatoes to be washed are continuously or in batches fed into the feeding area of ​​the frame 2. Under the action of the vibrating motor, the potatoes jump and tumble continuously along the movement path within the frame 2 towards the discharge area. During this process, the water pump 54 delivers water from the water tank 53 to the water pipe 51, which sprays downwards through the nozzle 52 to thoroughly wash the tumbling potatoes. The wastewater and silt generated during washing are separated through the screen plate 21.

[0039] 3. Drying and Water Removal: After rinsing, the potatoes continue to the area below the water blowing mechanism 6. The airflow generated by the blower passes through the ventilation grille 62 under the cover 61, blowing off most of the residual moisture on the surface of the potatoes.

[0040] 4. Discharge and Water Circulation: After washing and drying, the potatoes are finally discharged from the discharge area and enter the next process. At the same time, the wastewater generated in the rinsing process is separated by the screen plate 21 and guided by the guide plate 22 in the discharge area to flow back to the water tank 53. After sedimentation, it can be reused by the water pump 54, forming a water circulation system and saving water resources.

[0041] 5. Shutdown and Maintenance: After the cleaning operation is completed, turn off the blower, water pump 54, and vibrating motor in sequence. The screen plate 21 can be removed from the frame 2 periodically for thorough cleaning to maintain the best separation effect.
