By arranging the screening barrel 14 on the containing box 2, the screening barrel 14 can realize the screening of potatoes. After being conveyed to the containing box 2, the potatoes will first fall onto the screening barrel 14 and then be screened by the screening barrel 14. Small-sized potatoes will fall into the screening barrel 14 and be conveyed away, while large-sized potatoes will be driven by the paddle 15 and continue to move into the containing box 2, so that large-sized potatoes are gathered in the containing box 2, and potatoes of different sizes can be recycled in different ways, so that there is no need for subsequent screening, thereby reducing the labor intensity of personnel and reducing certain costs.

[0031] like Figure 1 As shown, the first servo motor 5 is coaxially arranged with the sieve barrel 14, the inner rod 16 and the screw rod 10 at the output end of the first servo motor 5 are located inside the sieve barrel 14, the first servo motor 5, the inner rod 16 and the screw rod 10 are not connected to the sieve barrel 14, the two side ends of the sieve barrel 14 are rotatably connected to the containing box 2, the upper end of the sieve barrel 14 passes through the containing box 2 and is located on the outside of the containing box 2, the upper end of the sieve barrel 14 is installed with a pulley 6, and the output end of the second servo motor 8 on the same side is also installed with a pulley 6, and the two ends are connected to the containing box 2. The transmission belt 7 can be connected between the side pulleys 6, the second servo motor 8 can independently control the screen barrel 14 to rotate, the screen barrel 14 can rotate toward the bottom of the holding box 2, the screen barrel 14 can transfer the potatoes to the bottom of the holding box 2, the potatoes will not stay at the angle between the screen barrel 14 and the holding box 2, nor will the potatoes be pushed into the angle. By setting the second servo motor 8, the screen barrel 14 can be driven to rotate independently, and the first servo motor 5 can independently drive the screw rod 10 to rotate.

[0032] Due to the tilted setting of the screen barrel 14, the first servo motor 5 and the second servo motor 8 also need to be tilted. The first servo motor 5 and the second servo motor 8 can be fixed by the fixed seat 4. The fixed seat 4 is installed on the side wall of the storage box 2 through long rods at the four corners. In order to make the fixed seat 4 cooperate with the tilt of the first servo motor 5 and the second servo motor 8, the lengths of the long rods at the upper and lower ends of the fixed seat 4 are different, so that the fixed seat 4 can be tilted during installation.

[0033] The sieve barrel 14 is cylindrical in shape as a whole, and the interior of the sieve barrel 14 is hollow. The sieve holes 17 are opened around the outer circumference of the sieve barrel 14. The diameter of the sieve holes 17 is larger than the diameter of the head 20 inside the sieve barrel 14. The head 20 is located inside the sieve barrel 14, and the head 20 is coaxially arranged with the corresponding sieve holes 17, and the head 20 faces the outside of the sieve barrel 14. Potatoes can be stored through the sieve barrel 14. After entering the sieve barrel 14, the potatoes will roll along the sieve barrel 14, so as to roll out of the sieve barrel 14. A recovery device can be placed at the output end of the sieve barrel 14 for storage. The potatoes in the holding box 2 can be transported through the conveyor bed 3, so as to realize the recovery and storage of potatoes of different sizes. By setting the sieve holes 17 on the sieve barrel 14, the sieve holes 17 can realize the entry of potatoes. The size of the sieve holes 17 can be adjusted according to demand, so as to adapt to the potatoes to be planted.

[0034] A fixing rod 18 is provided inside the screen barrel 14. The fixing rods 18 are arranged on both sides of the screen barrel 14, and the fixing rods 18 on both sides are arranged parallel to each other. Each fixing rod 18 is arranged along the length of the screen barrel 14. A corresponding fixing ring 21 is welded on the fixing rod 18, and the diameter of the fixing ring 21 is smaller than the diameter of the screen barrel 14. By providing the fixing rod 18 inside the screen barrel 14, the fixing rod 18 can rotate integrally with the screen barrel 14. By providing the fixing ring 21 on the fixing rod 18, the fixing ring 21 can be fixed on the fixing rod 18, and the fixing ring 21 can rotate with the fixing rod 18, so that it will not rotate alone, and the rotation angle of the fixing ring 21 can be the same as the rotation angle of the screen barrel 14.

[0035] In practice, the storage box 2 can store the harvested potatoes. When the potatoes are dug out and transported, they will fall into the storage box 2. After the screening barrel 14 is set in the storage box 2, the potatoes will fall onto the screening barrel 14. The screening barrel 14 is provided with a screening hole 17. The size of the screening hole 17 can be adjusted according to demand. Potatoes smaller than the screening hole 17 can enter the screening barrel 14, and potatoes larger than the size of the screening hole 17 will be taken away by the screening barrel 14. The screening barrel 14 is provided with a paddle 15. The plate 15 will push the large-sized potatoes into the holding box 2, so that potatoes of different sizes can be screened. When the screen barrel 14 is installed obliquely in the holding box 2, the potatoes will roll down due to the inclination of the screen barrel 14. A partition 24 is provided at the bottom of the screen barrel 14, and the partition 24 can wrap the screen barrel 14, so that when the potatoes fall to the bottom of the screen barrel 14, they will not enter the holding box 2. Through the setting, screening of different sizes can be achieved, thereby reducing the labor intensity of personnel and reducing certain costs.

[0036] The fixing ring 21 is arranged along the length of the fixing rod 18, and each fixing ring 21 is slidably connected with a sliding rod 22. The number of sliding rods 22 on each fixing ring 21 is the same as the number of sieve holes 17 in one circle of the sieve barrel 14. The sliding rod 22 on the fixing ring 21 is connected to the corresponding top head 20. The sliding rod 22 and the top head 20 are arranged in a T shape, and the sliding rod 22 is arranged in a rectangular shape as a whole. By arranging the sliding rod 22 on the fixing ring 21, the sliding rod 22 can move along the fixing ring 21. The sliding rod 22 is rectangular as a whole. When the sliding rod 22 moves along the fixing ring 21, the sliding rod 22 will not rotate, thereby ensuring that the sliding rod 22 will not rotate when it moves. The sliding rod 22 can drive the top head 20 away from or close to the sieve hole 17, thereby ensuring that the top head 20 pushes the potatoes in the sieve hole 17, thereby avoiding clogging in the sieve hole 17.

[0037] The slide bar 22 is connected to the fixed ring 21 through and through, one end of the slide bar 22 is located inside the fixed ring 21, and the other end of the slide bar 22 is located outside the fixed ring 21. An arc seat 23 is provided on the end of the slide bar 22 inside the fixed ring 21. The arc seat 23 is provided in a V-shape as a whole, and the arc seat 23 faces the screw rod 10 inside the screen barrel 14. By providing the arc seat 23 on the slide bar 22, the arc seat 23 will not rotate when the slide bar 22 moves, and the two slope ends of the arc seat 23 can correspond to the first cone head 11 and the second cone head 12. When the first cone head 11 and the second cone head 12 reciprocate along the screw rod 10, the arc seat 23 will be pushed, thereby realizing the movement of the slide bar 22.

[0038] The first servo motor 5 is detachably connected with a cross bar 13, which is parallel to the screw rod 10, and is connected to the corresponding first cone head 11 and the second cone head 12. The cross bar 13 is the same length as the screw rod 10, and the diameter of the cross bar 13 is smaller than the diameter of the screw rod 10. By setting the cross bar 13, the cross bar 13 can be fixedly installed on the first servo motor 5, and the cross bar 13 will not rotate when the screw rod 10 rotates. When the screw rod 10 and the cross bar 13 are installed on the first cone head 11 and the second cone head 12, the first cone head 11 and the second cone head 12 can move along the screw rod 10 and will not rotate with the screw rod 10.

[0039] The first conical head 11 and the second conical head 12 on the screw rod 10 are welded to each other, the large ends of the first conical head 11 and the second conical head 12 are welded to each other, and the small ends of the first conical head 11 and the second conical head 12 face the corresponding arc seat 23. By setting the first conical head 11 and the second conical head 12, the first conical head 11 and the second conical head 12 can push the arc seat 23, and the arc seat 23 can move along the conical head, thereby changing the position of the arc seat 23, and finally changing the position of the head 20.

[0040] A paddle 15 is provided on the screen barrel 14 inside the storage box 2, and the paddle 15 is arranged along the length of the screen barrel 14. The screen barrel 14 is arranged obliquely on the storage box 2, and the output end of the screen barrel 14 is open. A partition 24 is provided below the screen barrel 14 in the storage box 2, and the partition 24 is arranged along the length of the screen barrel 14. The partition 24 is parallel to the axis of the screen barrel 14. The paddle 15 can drive the potatoes to move by setting the paddle 15, thereby preventing the potatoes from being stuck at the connection between the screen barrel 14 and the storage box 2.

[0041] The paddle plate 15 on the screen barrel 14 is arranged in a trapezoidal shape as a whole, and the heights of the two ends of the paddle plate 15 are different. By tilting the screen barrel 14, the shape of the paddle plate 15 is adjusted accordingly, so that the paddle plate 15 can contact the containing box 2 to prevent potatoes from entering the containing box 2 through the connection.

[0042] The input end of the sieve barrel 14 and the output end of the second servo motor 8 are both provided with pulleys 6, and a transmission belt 7 is sleeved between the pulleys 6. The first servo motor 5 and the second servo motor 8 are both detachably connected to the fixing seat 4. The output end of the first servo motor 5 is provided with an inner rod 16, which penetrates and connects the input end of the sieve barrel 14. A screw rod 10 is welded on the inner rod 16 inside the sieve barrel 14. The first servo motor 5 can drive the sieve barrel 14 through the transmission belt 7, so that the sieve barrel 14 can rotate independently, and the screw rod 10 will not affect the rotation of the sieve barrel 14 when it moves.

[0043] In the implementation, an inner rod 16 is arranged on the first servo motor 5, one end of the inner rod 16 is located inside the sieve barrel 14, a screw rod 10 is arranged on the inner rod 16 inside the sieve barrel 14, and the screw rod 10 is threadedly connected to the first conical head 11 and the second conical head 12. The first servo motor 5 is also connected to a cross bar 13, and the cross bar 13 and the screw rod 10 are simultaneously installed on the first conical head 11 and the second conical head 12. The position of the cross bar 13 is fixed, and when the screw rod 10 rotates, the first conical head 11 and the second conical head When the first conical head 11 and the second conical head 12 move to the arc seat 23 of the slide bar 22, they push the slide bar 22 to move, so that the push head 20 moves toward the sieve hole 17, so that the potatoes stuck in the sieve hole 17 can be pushed out, and the small-sized potatoes will not be squeezed by the push head 20 after entering the sieve barrel 14 due to their size and moving speed, thereby ensuring the integrity of the potatoes.

[0044] The working principle of the present invention is as follows: during the use of the equipment, the conveying frame 1 is driven by the traction device, the front end of the conveying frame 1 will extend into the soil, and the potatoes will be scooped up as it moves. After scooping up, the chain conveying component on the conveying frame 1 will convey the potatoes to the containing box 2. Before the potatoes enter the containing box 2, they will fall onto the screen barrel 14. The large-sized potatoes that cannot enter the inside of the screen barrel 14 will be conveyed to the inside of the containing box 2 by the shifting plate 15, and then conveyed away by the conveying bed 3. The small-sized potatoes that enter the inside of the screen barrel 14 will be discharged from the lower part of the screen barrel 14 due to the inclination of the screen barrel 14, thereby realizing the graded conveying of potatoes. The storage box 2 can store the harvested potatoes. When the potatoes are dug out and transported, they will fall into the storage box 2. After the screening barrel 14 is set in the storage box 2, the potatoes will fall onto the screening barrel 14. The screening barrel 14 is provided with screening holes 17. The size of the screening holes 17 can be adjusted according to demand. Potatoes smaller than the screening holes 17 can enter the screening barrel 14, and potatoes larger than the screening holes 17 will be taken away by the screening barrel 14. The screening barrel 14 is provided with a paddle 15. The paddle 15 15 will push the large-sized potatoes into the holding box 2, so that potatoes of different sizes can be screened. When the screen barrel 14 is tilted and installed in the holding box 2, the potatoes will roll down due to the tilt of the screen barrel 14. The bottom of the screen barrel 14 is provided with a partition 24, and the partition 24 can wrap the screen barrel 14, so that when the potatoes fall to the bottom of the screen barrel 14, they will not enter the holding box 2. By setting, screening of different sizes can be achieved, thereby reducing the labor intensity of personnel and reducing a certain cost. In the present invention, an inner rod 16 is arranged on the first servo motor 5, one end of the inner rod 16 is located inside the sieve barrel 14, a screw rod 10 is arranged on the inner rod 16 inside the sieve barrel 14, and the screw rod 10 is threadedly connected to the first conical head 11 and the second conical head 12, and a cross bar 13 is also connected to the first servo motor 5, and the cross bar 13 and the screw rod 10 are simultaneously installed on the first conical head 11 and the second conical head 12, and the position of the cross bar 13 is fixed. When the screw rod 10 rotates, the first conical head 11 and the second conical head 1 2 will reciprocate along the screw rod 10, and will not rotate with the screw rod 10 after being restricted by the cross bar 13. When the first conical head 11 and the second conical head 12 move to the arc seat 23 of the slide bar 22, they will push the slide bar 22 to move, so that the push head 20 moves to the sieve hole 17, so that the potatoes stuck in the sieve hole 17 can be pushed out, and small-sized potatoes will not be squeezed by the push head 20 after entering the sieve barrel 14 due to their size and moving speed, thereby ensuring the integrity of the potatoes.
