[0022] The application will be further described below in conjunction with the drawings.

[0023] As shown in the drawings Figures 1 to 5 The automatic picking and separating device for radish comprises a vehicle body 1 that can move, and tracks are arranged on both sides of the vehicle body 1 to make the off-road capability of the vehicle body 1 stronger. The vehicle body 1 is further provided with a clamping and pulling device 2, a cutting device 3, a stem and leaf conveying belt 4 and a radish conveying belt 5.

[0024] The clamping and pulling device 2 comprises a plurality of clamping and pulling units 6, and each clamping and pulling unit 6 comprises two opposite rotary belts 7. The belt surfaces of the two rotary belts 7 are opposite to each other, and the distance between the belt surfaces of the two rotary belts 7 is separated, so that a clamping and pulling conveying channel 8 is formed between the two rotary belts 7. When the vehicle body 1 moves, the oblique lower end of the clamping and pulling conveying channel 8 is opposite to the stem and leaf part of the radish. With the movement of the vehicle body 1, the stem and leaf of the radish is clamped into the clamping and pulling conveying channel 8, and then the two opposite rotary belts 7 clamp the stem and leaf of the radish. Then the rotary belts 7 rotate, so that the radish is displaced obliquely upward along the clamping and pulling conveying channel 8 and then pulled out, thereby realizing the picking of the radish.

[0025] The cutting device 3 is arranged at the clamping and pulling conveying channel 8, as shown in the drawings Figure 4 The cutting device 3 is arranged close to the oblique upper end of the clamping and pulling conveying channel 8, and the radish and the stem and leaf that are displaced along the clamping and pulling conveying channel 8 are cut and separated by the cutting device 3. After the cutting device 3 cuts the radish and the stem and leaf, the separated radish falls onto the radish conveying belt 5. The separated stem and leaf is still clamped by the rotary belts 7, so the stem and leaf will continue to be displaced obliquely upward to the end of the clamping and pulling conveying channel 8, and then the stem and leaf is pulled out from the end of the clamping and pulling conveying channel 8 and falls onto the stem and leaf conveying belt 4, thereby realizing the separation of the radish and the stem and leaf.

[0026] As shown in the drawings Figure 4As shown, the cutting device 3 includes two disc cutters 9 arranged opposite each other, with the edges of the two disc cutters 9 touching. Both disc cutters 9 can rotate actively under the drive of a motor. The connection between the stem and leaves and the radish is opposite to the connection between the two disc cutters 9. When the radish moves obliquely downward along the clamping and conveying channel 8 and passes between the two disc cutters 9, the two disc cutters 9 cooperate to cut the stem and leaves on the radish, thereby separating the radish from the stem and leaves.

[0027] As attached Figure 1 As shown, the clamping units 6 on the clamping device 2 are arranged side by side, so the total width of the clamping units 6 is relatively large. If the width of the radish conveyor belt 5 is comparable to the total width of the clamping units 6, the total width of the vehicle body 1 will be large, and the volume of the vehicle body 1 will also be large. In order to reduce the total volume of the vehicle body 1 and improve the space utilization within the vehicle body 1, the width of the radish conveyor belt 5 is made smaller than the total width of the clamping units 6. In this way, at least one clamping unit 6 is offset from the radish conveyor belt 5. (See attached diagram) Figure 4 As shown, the clamping units 6 on both sides are staggered from the radish conveyor belt 5, so the radishes on the clamping units 6 on the edges cannot fall directly onto the radish conveyor belt 5.

[0028] Therefore, in this invention, within the clamping unit 6, which is offset from the radish conveyor belt 5, a rotating disk 10 is provided below the disc cutter 9 of the cutting device 3. The rotating disk 10 can rotate actively, and a piercing structure 11 is provided on the outer ring of the rotating disk 10. The piercing structure 11 can be a needle, sharp teeth, etc., and can pierce into the radish after it has been separated from the stems and leaves. After separation from the stems and leaves, some stems and leaves remain at the upper end of the radish. The piercing structure 11 pierces into the remaining stems and leaves at the upper end of the radish, avoiding damage to the radish body. When the radish rotates a certain angle with the rotating disk 10, the radish will detach from the piercing structure 11, and then the radish will be thrown onto the radish conveyor belt 5. This allows the clamping unit 6, which is offset from the radish conveyor belt 5, to also send the radish onto the radish conveyor belt 5, thus satisfying the condition that the width of the radish conveyor belt 5 is less than the total width of the multiple clamping units 6. This reduces the width of the vehicle body 1 and improves the space utilization rate inside the vehicle body 1.

[0029] As attached Figure 5 As shown, a guide bar 12 is provided below the rotating disk 10. The guide bar 12 is fixed below the bracket of the clamping unit 6 and is inclined and points towards the radish conveyor belt 5. After the radish separates from the stem and leaves and the piercing structure 11 pierces the radish, the radish will rotate with the rotating disk 10. When the radish rotates with the rotating disk 10 at a certain angle, the radish will hit the guide bar 12 and slide a certain distance along the guide bar 12 before detaching from the piercing structure 11 and being thrown onto the radish conveyor belt 5. By setting the guide bar 12, the direction of the radish being thrown can be controlled to ensure that the radish is thrown onto the radish conveyor belt 5.

[0030] The linear velocity of the piercing structure 11 is similar to the moving speed of the radish in the clamping and conveying channel 8, so that the piercing structure 11 will not cut the radish due to the speed difference. If the linear velocity of the piercing structure 11 is greater than or less than the moving speed of the radish in the clamping and conveying channel 8, the piercing structure 11 will directly cut the radish, and the rotating disk 10 will not be able to drive the radish to rotate through the piercing structure 11.

[0031] As attached Figure 5 As shown, in the clamping unit 6 offset from the radish conveyor belt 5, the rotating disk 10 is positioned below the disc cutter 9 on one side of the cutting device 3, closer to the radish conveyor belt 5, making it easier for the radish to be thrown onto the radish conveyor belt 5. The disc cutter 9 on this side is coaxially connected to the rotating disk 10 and rotates synchronously. That is, the disc cutter 9 on this side and the rotating disk 10 are mounted on the same rotating shaft. When the motor drives the rotating shaft to rotate, it drives the rotating disk 10 and the disc cutter 9 on this side to rotate synchronously.

[0032] Within the clamping unit 6, which is offset from the radish conveyor belt 5, the disc cutter 9 connected to the rotating disk 10 rotates in the opposite direction to the disc cutter 9 on the other side, and the rotational speed of the disc cutter 9 on the other side is greater than that of the disc cutter 9 connected to the rotating disk 10. Since the linear velocity of the piercing structure 11 is similar to the moving speed of the radish within the clamping conveyor channel 8, the linear velocity of the disc cutter 9 on the same side as the rotating disk 10 is also similar to the moving speed of the radish within the clamping conveyor channel 8. To achieve a better cutting effect, the rotational speed of the disc cutter 9 on the other side needs to be greater. A better cutting effect is achieved through the difference in rotational speeds between the two disc cutters 9. The rotational directions of the two disc cutters 9 can be referenced in the attached diagram. Figure 5 As shown in the image.

[0033] In order to reduce the width of the vehicle body 1, the width of the stem-and-leaf conveyor belt 4 is correspondingly smaller than the total width of the multiple clamping units 6. Therefore, at least one clamping unit 6 is offset from the stem-and-leaf conveyor belt 4, as shown in the attached diagram. Figure 4 As shown, stems and leaves falling from the edge of the clamping unit 6 cannot fall directly onto the stem and leaf conveyor belt 4. The end of the clamping unit 6 is provided with an inclined guide plate 17, which gradually narrows from one end near the clamping unit 6 to the other end near the stem and leaf conveyor belt 4, allowing stems and leaves falling from the clamping unit 6 to slide along the inclined guide plate 17 onto the stem and leaf conveyor belt 4.

[0034] If the guide plate is also used between the clamping and pulling unit 6 and the radish conveying belt 5, since the radish separated from the stem and leaf is below the clamping and pulling unit 6, a certain space needs to be left between the guide plate and the clamping and pulling unit 6 for the radish to pass through, and the guide plate itself will have a certain height, so that the use of the guide plate between the clamping and pulling unit 6 and the radish conveying belt 5 will increase the distance between the clamping and pulling unit 6 and the radish conveying belt 5, resulting in the height of the vehicle body 1 being higher, and the overall volume of the vehicle body 1 cannot be effectively reduced, so the rotating disc 10 and the puncture structure 11 are used in cooperation between the clamping and pulling unit 6 and the radish conveying belt 5.

[0035] As shown in the accompanying drawings, the output end of the stem and leaf conveying belt 4 is connected with a separation chute 13, and the stem and leaf separated from the radish falls onto the stem and leaf conveying belt 4, and then the stem and leaf falls along the stem and leaf conveying belt 4 to the separation chute 13, and then slides along the separation chute 13 to slide out of the vehicle body 1, so as to discharge the stem and leaf out of the vehicle body 1. Figure 2 As shown in the accompanying drawings, the output end of the radish conveying belt 5 is connected with a vibrating screen 14, and the rear end of the vibrating screen 14 is connected with a storage basket 15. The radish separated from the stem and leaf is screened on the vibrating screen 14 to remove the adhered soil, and gradually moves to the storage basket 15 under the vibration of the vibrating screen 14, so as to harvest the picked radish into the storage basket.

[0036] Figure 2 The working mode of the present application is as follows: the two sides of the obliquely lower end of the clamping and pulling unit 6 are provided with a soil loosening shovel 16, in the process of picking radish, the vehicle body 1 moves forward, the soil loosening shovel 16 loosens the soil at the bottom of the radish, so as to realize fruit and soil separation and reduce the pulling force, and avoid the stem and leaf being pulled off during the radish pulling process, causing missed pulling; then the stem and leaf is clamped into the clamping and pulling conveying channel 8, under the action of the rotating belt 7, the radish is pulled out of the soil and conveyed obliquely upward to the cutting device 3, the cutting device 3 separates the radish from the stem and leaf; in the clamping and pulling unit 6 opposite to the radish conveying belt 5, the radish separated from the stem and leaf directly falls onto the radish conveying belt 5; and in the clamping and pulling unit 6 staggered with the radish conveying belt 5, the upper end of the radish separated from the stem and leaf is pierced by the puncture structure 11 on the rotating disc 10, then the radish rotates with the rotating disc 10 by a certain angle, and then the radish will hit the guide bar 12 and move along the guide bar 12, the radish is separated from the puncture structure 11 and is thrown onto the radish conveying belt 5; the radish on the radish conveying belt 5 moves forward to the vibrating screen 14, the soil is screened out, and gradually moves to the storage basket 15; and the stem and leaf separated from the radish continues to move to the obliquely upper end of the clamping and pulling conveying channel 8 and then falls out, slides along the oblique guide plate 17 to the stem and leaf conveying belt 4, and then falls out of the vehicle body 1 from the separation chute 13 and returns to the radish field.

[0037] The working mode of the present application is as follows: the two sides of the obliquely lower end of the clamping and pulling unit 6 are provided with a soil loosening shovel 16, in the process of picking radish, the vehicle body 1 moves forward, the soil loosening shovel 16 loosens the soil at the bottom of the radish, so as to realize fruit and soil separation and reduce the pulling force, and avoid the stem and leaf being pulled off during the radish pulling process, causing missed pulling; then the stem and leaf is clamped into the clamping and pulling conveying channel 8, under the action of the rotating belt 7, the radish is pulled out of the soil and conveyed obliquely upward to the cutting device 3, the cutting device 3 separates the radish from the stem and leaf; in the clamping and pulling unit 6 opposite to the radish conveying belt 5, the radish separated from the stem and leaf directly falls onto the radish conveying belt 5; and in the clamping and pulling unit 6 staggered with the radish conveying belt 5, the upper end of the radish separated from the stem and leaf is pierced by the puncture structure 11 on the rotating disc 10, then the radish rotates with the rotating disc 10 by a certain angle, and then the radish will hit the guide bar 12 and move along the guide bar 12, the radish is separated from the puncture structure 11 and is thrown onto the radish conveying belt 5; the radish on the radish conveying belt 5 moves forward to the vibrating screen 14, the soil is screened out, and gradually moves to the storage basket 15; and the stem and leaf separated from the radish continues to move to the obliquely upper end of the clamping and pulling conveying channel 8 and then falls out, slides along the oblique guide plate 17 to the stem and leaf conveying belt 4, and then falls out of the vehicle body 1 from the separation chute 13 and returns to the radish field.
