[0002] Potatoes, also known as ground eggs and sweet potatoes, are annual plants of the Solanaceae family. They are also known as ground eggs and sweet potatoes, but are most commonly called "potatoes." They grow 15-80 cm tall, are glabrous or sparsely pubescent, and have stems consisting of an aboveground stem and an underground stem. Potatoes are one of China's five major staple foods. Their high nutritional value, adaptability, and high yield make them the world's third most important food crop, after wheat and corn.

The user can control the operation of the motor three 13 according to actual needs and use the worm 12 and worm gear 11 to drive the rotating shaft 10, the mounting plate 4 and the scraper 5 to rotate and adjust the angle of the scraper 5, thereby effectively improving the applicability of the device.

[0030] Furthermore, the motor 3 13 is fixedly connected to the frame 1 through a mounting base, a plurality of universal wheels 2 are fixedly provided on the bottom surface of the frame 1, and a towing rack 6 is fixedly provided on the left end of the frame 1.

[0031] Refer to the attached Figure 4 The conveying mechanism 3 includes two fixed plates 31, the left ends of the two fixed plates 31 are fixedly connected to the frame 1, and the two fixed plates 31 are rotatably connected to the two transmission shafts 33 through bearings.

[0032] Furthermore, two sprockets 34 are fixedly provided on each transmission shaft 33, and the four sprockets 34 are grouped in pairs and the two groups of sprockets 34 are connected by chains 32. The opposite surfaces of the two chains 32 are fixedly connected to the two ends of multiple steel bars 310 respectively. When the motor 1 36 is working, the brush roller 39 and multiple steel bars 310 are driven to rotate through the pulley 1 37, the pulley 2 38, the sprocket 34, the transmission shaft 33 and the chain 32. When the device moves, multiple shovels 5 are used to dig potatoes in the soil. The dug potatoes move along the shovel 5 to the steel bar 310 at the left end. At this time, the rotation of the steel bar 310 is used to drive the potatoes to the right. When the potatoes move to the bottom of the brush roller 39, the soil on the surface of the potatoes is cleaned, thereby improving the cleanliness of the potatoes harvested by this device.

[0033] Furthermore, the rear end of the right transmission shaft 33 is fixedly connected to the output shaft of motor 1 36, and motor 1 36 is fixedly connected to the frame 1 through a mounting base. A pulley 1 37 is fixedly provided on the rear side of the right transmission shaft 33, and pulley 1 37 is connected to pulley 2 38 through a belt.

[0034] Furthermore, the pulley 2 38 is fixedly arranged on the brush roller 39 and is rotatably connected to the upper ends of the two fixed plates 2 35 through bearings, and the bottom ends of the two fixed plates 2 35 are fixedly connected to the two fixed plates 1 31 respectively.

[0035] Refer to the attached Figure 5 The screening mechanism 7 includes a support frame 71 , the left end of the support frame 71 is fixedly connected to the frame 1 , and the left side of the upper surface of the support frame 71 is fixedly connected to the bottom surfaces of the two guide plates 72 at the same time.

[0036] Furthermore, the right side of the support frame 71 is rotatably connected to the connecting shaft 77 through a bearing, the bottom end of the connecting shaft 77 is fixedly connected to the output shaft of the motor 2 74, and the motor 2 74 is fixedly connected to the bottom surface of the support frame 71 through a mounting seat.

[0037] Furthermore, a plurality of dial plates 75 are fixedly provided on the connecting shaft 77, and the plurality of dial plates 75 are all sleeved in the baffle 73. The bottom surface of the baffle 73 is fixedly connected to the support frame 71. Three screening slots 76 are provided in the support frame 71, and the three screening slots 76 are all arranged around the outside of the connecting shaft 77. The widths of the three screening slots 76 are set differently. When the motor 2 74 is working, it drives the connecting shaft 77 and the dial plate 75 to rotate. When the potato moves to the right end of the guide plate 72, the rotating dial plate 75 is used to drive the potato to rotate backward along the connecting shaft 77. At this time, the potato passes through the plurality of screening slots 76 with gradually increasing widths in turn. When the potato rolls on the screening slot 76, the potato of the corresponding size falls into the storage box 8 through the screening slot 76 for classification and storage, so that the grower does not need to manually screen the potato in the future, which effectively reduces the workload of the grower.

[0038] The working principle of the present utility model is as follows: when using the device to harvest potatoes, the user can use the towing frame 6 to connect the device to the tractor, and then use the tractor to move the device to the field.

When the motor 1 36 is working, it drives the brush roller 39 and the multiple steel bars 310 to rotate through the pulley 1 37, the pulley 2 38, the sprocket 34, the transmission shaft 33 and the chain 32. When the motor 2 74 is working, it drives the connecting shaft 77 and the paddle plate 75 to rotate.

[0039] At this time, the tractor can be used to drive the device to move. When the device moves, multiple shovels 5 are used to dig potatoes in the soil. The dug potatoes move along the shovel 5 to the steel bar 310 at the left end. At this time, the rotation of the steel bar 310 drives the potatoes to move to the right. When the potatoes move under the brush roller 39, the soil on the surface of the potatoes is cleaned. When the potatoes move to the right end of the conveying mechanism 3, they fall to the left side of the support frame 71. As the potatoes accumulate, the potatoes move to the right along the guide plate 72. When the potatoes move to the right end of the guide plate 72, the rotating dial plate 75 is used to drive the potatoes to rotate backward along the connecting shaft 77. At this time, the potatoes pass through multiple screening slots 76 with gradually increasing widths in turn. When the potatoes roll on the screening slots 76, potatoes of corresponding sizes fall into the storage box 8 through the screening slots 76 for classification and storage. When the storage box 8 is full, the storage box 8 is pulled to the right so that the connecting plate 14 is disengaged from the chute 9, the storage box 8 is removed and the potatoes are cleaned.

[0040] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
