When the machine is running, the seedling clamping driven shaft 413 drives the seedling pairing driving shaft 521 to provide power for this part, and drives the seedling rowing front shaft 541 to rotate through the sprocket and chain, thereby rotating the seedling pairing rear wheel 525 and the seedling rowing front wheel 543, and further driving the seedling pairing belt 522 and the seedling rowing belt 542 to rotate, so that the seedling pairing reverse tensioning wheel 524, the seedling pairing rear wheel 525, the seedling rowing tensioning wheel 544 and the seedling rowing rear wheel 545 are rotated, thereby ensuring that the roots and fruits run smoothly during the process of pulling and cutting the tassels.

[0133] The pulling and cutting tassel device 5 is used to connect the clamping device 4, and is connected and transported by two conveyor belts (seedling belt 522 and seedling row belt 542) up and down to ensure that the root fruit and the tassel leaves are effectively separated under the premise that the seedlings are not damaged. Generally, the tassel leaves are retained at 3-5 cm. The cutting length can be adjusted according to the height of the tassel leaves clamped by the clamping device 4 and the height position of the tassel cutting mechanism 53, so that the root fruit falls from the bottom of the pulling and cutting tassel device 5 to the conveyor belt of the horizontal conveying device 3, and the tassel leaves are discharged and dropped from the upper part of the pulling and cutting tassel device 5. The seedling pairing mechanism 52 and the clamping device 4 are close to each other, so that the seedling clamping belt 418 can smoothly transfer the clamped tassels to the seedling pairing belt 522, forming an effective connection, avoiding the root and fruit falling off and bumping at the connection point, and a weeding component can be provided on the pulling and cutting frame 51, which is located 1-2mm away from each pulley and forms a certain angle with its rotation direction to prevent the tassels from being entangled in the pulley and the inner side of the seedling pairing belt 522 and the seedling discharge belt 542, causing the seedling pairing belt 522 and the seedling discharge belt 542 to slip; the seedling pairing belt 522, the seedling front wheel 523, the seedling reverse tensioning wheel 524 and the seedling rear wheel 525 are used to connect the roots and fruits and transport them to the tassel cutting device. During the transportation process, the roots and fruits are first connected to the seedling front wheel 523 from the rear of the clamping device 4 and then pulled and transported. The seedling front wheel 5 23 is different from other pulleys. One side of its lower end needs to cut around the disc at a larger angle to prevent the root fruit from being squeezed and colliding with the bottom of the tassel connection during the handover from the clamping belt to the vine belt 522, which may cause damage to the root fruit; the tassel cutting mechanism 53 is a hydraulically driven disc cutter, and the rotation of the disc cutter can improve the tassel cutting rate; the vine belt 542, the vine front wheel 543, the vine tensioning wheel 544 and the vine rear wheel 545 are used to connect with the vine clamping device to transport the upper tassels of white radish. The front half of this part is to pull the tassels into line in preparation for the tassel cutting process. In the second half, after the tassel cutting is completed and the root fruit falls off, the vine belt 542 continues to clamp the cut tassels and move backward until it passes over the transverse conveyor belt 38 to prevent the cut tassels from falling onto the conveyor belt, thereby reducing the impurity rate.

Figure 6EThe figure is a schematic diagram of the inclination angle of the longitudinal tassel-supporting mechanism of an embodiment of the present invention. The tassel-supporting device 6 of this embodiment adopts bionic finger-moving to actively rotate the bidirectional tassels to gather the tassels of the white radish to be harvested, including two transverse tassel-supporting mechanisms 61 and one longitudinal tassel-supporting mechanism 62. The transverse tassel-supporting mechanism 61 and the longitudinal tassel-supporting mechanism 62 respectively include: a tassel-supporting frame 611, which is installed on the clamping mechanism 41 and is used to adjust the position and inclination angle of the transverse tassel-supporting mechanism 61 and the longitudinal tassel-supporting mechanism 62; a tassel-supporting driving motor 612, which is installed on the tassel-supporting frame 611; a tassel-supporting driving wheel 614, which is installed on the tassel-supporting frame 611 and connected to the tassel-supporting driving motor 612; a tassel-supporting driven wheel 615, which is connected to the tassel-supporting driving wheel 614 through a tassel-supporting belt 617; a motor tensioner 616. The tightening component 613 is installed at the upper end of the seedling supporting frame 611, and is used to adjust the connection position of the seedling supporting drive motor 612 and the seedling supporting active wheel 614; the seedling supporting outer guard plate 616 is installed on the seedling supporting frame 611 and is located on the outside of the seedling supporting active wheel 614 and the seedling supporting driven wheel 615; and the weeding component 618 is installed on the seedling supporting driven wheel 615, and is used together with the seedling supporting outer guard plate 616 to prevent the seedlings from being entangled and the seedling belt 617 from slipping. It is preferred to install the weeding component 618 at 1-2 mm of the seedling supporting driven wheel 615, and the weeding scraper cooperates with the groove of the seedling supporting driven wheel 615 to prevent the seedlings from being entangled with the pulley and causing problems such as belt slippage and pulley blockage.

[0135] In this embodiment, one end of the rice seedling supporting frame 611 is connected to the front end of the clamping mechanism 41 by a bolt, and the other end is connected to the outer guard plate 616 of the rice seedling supporting frame. The horizontal rice seedling supporting mechanisms 61 on the left and right sides are respectively provided with an inner guard plate and an outer guard plate, and the middle longitudinal rice seedling supporting mechanism 62 has only an outer guard plate. The rice seedling supporting drive motor 612 is placed in the semicircular groove on the upper part of the rice seedling supporting frame 611, and the motor tensioning component 613 passes through the rice seedling supporting drive motor 612 and is buckled on the upper end of the rice seedling supporting frame 611, and the tensioning adjustment is achieved by bolts and nuts. The output shaft of the rice seedling supporting drive motor 612 is connected to the rice seedling supporting active wheel 614, and the two rice seedling supporting driven wheels 615 are respectively assembled with the rice seedling supporting frame 611 , installed in the middle and lower parts and rotated by the supporting belt 617, the supporting belt 617 cooperates with the supporting active wheel 614 and the two supporting driven wheels 615, the left and right side horizontal supporting mechanisms 61 are equipped with two supporting belts 617, and during assembly, the fingers of the two supporting belts 617 need to be staggered by a certain position to achieve the best supporting effect, the middle longitudinal supporting mechanism 62 is only equipped with one supporting belt 617, and the weeding component 618 is installed at a distance of 1-2mm from the bottom supporting driven wheel 615, and the left and right side horizontal supporting mechanisms 61 and the middle longitudinal supporting mechanism 62 are connected to the supporting frame 611 by bolts.

[0136] The tassel-supporting device 6 is used to gather the tassels of white radish that need to be spread out due to growth, lift the tassels and connect them with the clamping frame 411 to prepare for subsequent clamping and transporting. It adopts a bionic finger-type active rotating two-way tassel-supporting structure, consisting of two horizontal tassel-supporting mechanisms 61 and a longitudinal tassel-supporting mechanism 62. This structure can effectively avoid congestion and missed harvesting caused by the tassels during the harvest process. When the longitudinal tassel-supporting mechanism 62 has a certain inclination angle, the tassel-supporting effect is better. Preferably, the inclination angle range of the longitudinal tassel-supporting mechanism 62 is between 75° and 90°. The clamping frame 411 is used to support the seedling supporting drive motor 612 and the seedling supporting outer guard plate 616; the seedling supporting outer guard plate 616 is used to prevent the seedlings from being caught between the seedling supporting active wheel 614, the seedling supporting driven wheel 615 and the seedling supporting belt 617, affecting the rotation of the seedling supporting active wheel 614 and the seedling supporting driven wheel 615, causing the seedling supporting belt 617 to slip. At the same time, the seedling supporting driven wheel 615 is provided with a weeding component 618 to prevent the occurrence of this phenomenon; the seedling supporting belt 617 is provided with a bionic finger-type seedling supporting finger, and this structure can greatly improve the seedling supporting rate.

[0137] The tassel-lifting belt 617 rotates at a uniform speed to achieve the "lifting" and "gathering" of the radish tassels. The tassels change from a scattered state to a gathered "bundled" state, which improves the uprightness of the radish tassels and facilitates the subsequent feeding of the clamping device 4. The ordinary tassel-lifting fingers are in plane contact with the tassels, and the shaking of the tassels is uncertain, which may cause the tassels to slip, and the tassels may be lifted in the early stage of the tassel-lifting process, but as the harvester moves forward and vibrates, the tassels may slip into the tassel-lifting area, which in turn reduces the success rate of tassel-lifting. The bionic finger-type tassel-lifting fingers can effectively increase the success rate of feeding the tassels because the end is provided with a slope similar to the finger shape, and can prevent the tassels from falling after feeding. The bionic finger-type tassel-lifting fingers can select the side view of the finger when pulling the radish and import it into MATLAB for morphological operation, use the Canny operator to complete edge detection, and input the command to retrieve the contour coordinate value. Since the supporting device 6 rotates at high speed during operation, the fingertip should not be too sharp, so the relatively smooth junction between the first fingertip and the first knuckle of the index finger is selected as the terminal of the bionic fingertip.

[0138] See also Figure 7 , Figure 7The figure is a schematic diagram of the internal structure of the lateral conveying device 8 according to an embodiment of the present invention. The lateral conveying device 8 of this embodiment includes a lateral conveying support frame 84, a lateral conveying driven roller 81, a lateral conveying frame 82, a lateral conveying baffle 83, a lateral lifting cylinder 85, a lateral conveying frame 86, a lateral conveying motor 87 and a lateral conveying belt 88. The lateral conveying frame 86 is connected to the traveling frame 11 and the lateral lifting cylinder 85 respectively, the lateral lifting cylinder 85 is connected to the lateral conveying support frame 84, and the lateral conveying frame 82 is connected to the upper part of the lateral conveying baffle 83 and the lateral conveying support frame 84 respectively; the lateral conveying belt 88 is assembled on the transverse conveying active roller 32, the transverse conveying driven roller 33 and the lateral conveying driven roller 81; the lateral conveying driven roller 81 is located between the transverse conveying active roller 32 and the transverse conveying driven roller 33; and the lateral conveying motor 87 is connected to the transverse conveying active roller 32 via a chain.

[0139] In this embodiment, the lateral conveying frame 86 is connected to the walking frame 11 and the lateral lifting cylinder 85 respectively. The other end of the lateral lifting cylinder 85 is connected to the lateral conveying support frame 84. The lateral conveying frame 82 and the upper part of the lateral conveying baffle 83 are connected in sequence on the lateral conveying support frame 84. The lower part of the lateral conveying baffle 83 is connected to the lateral conveying frame 86. By means of the lateral conveying active roller 32, the lateral conveying driven roller 33 and the conveyor belt support plate 34, the two sides of the conveyor belt support plate 34 are connected to the inside of the lateral conveying frames 82 on both sides. The lateral conveyor belt 88 bypasses the lateral conveying active rollers 32, the lateral conveying driven rollers 33 and the lateral conveying driven roller 81 in the middle and is installed on the outside thereof. The lateral conveying motor 87 drives the lateral conveying active roller 32 and the lateral conveying driven roller 33 to rotate through the chain to drive the entire lateral conveyor belt 88 to rotate.

[0140] The lateral conveying device 8 of this embodiment is used to screen, sort, lift, and load fruits from the transverse conveying device 3. The lateral conveying baffle 83 prevents fruits from falling during transportation on the lateral conveyor belt 88. The lateral conveying support frame 84 supports the upper end of the lateral conveyor. The lateral conveying frame 86 supports the lower end of the lateral conveyor and fixes the lateral conveyor device 8. The lateral conveying driven roller 81 is connected to the lateral conveying frame 86 and the lower part of the lateral conveying frame 82, respectively, and is located between the two to enable the upper and lower ends of the lateral conveyor to rotate relative to each other. The lateral lifting cylinder 85 connects the upper and lower parts of the lateral conveyor, and the lateral conveying motor 87 drives the upper part of the lateral conveyor to complete the expansion and folding.

[0141] See also Figure 8 , Figure 8The figure shows the structure of a picking device 9 according to an embodiment of the present invention. In this embodiment, the picking device 9 can also be included to sort out and remove unqualified white radishes, such as those that are damaged or undersized, transported by the transverse conveyor belt 38, eliminating the need for subsequent sorting. The picking device 9 is mounted on the traveling chassis 1 and positioned between the transverse conveyor 3 and the lateral conveyor 8. The picking device 9 is used to sort the white radishes transported by the transverse conveyor 3 to ensure that the white radishes delivered to the lateral conveyor 8 are of good quality. The picking device 9 includes a seat frame 91, a picking seat 92, a fence revolving door 93 and an observation panel 94. The seat frame 91 is used to support other parts of the picking device 9 and is installed at the rear end of the walking frame 11; the picking seat 92 is installed on the seat frame 91 for workers to sit and complete the picking work; the fence revolving door is pivotally connected to the seat frame 91 with a hinge and is located behind the picking seat 92. It can be rotated backward and opened. In case of emergency, it can be opened at any time and automatically locked when the machine is running to ensure the safety of the workers; the observation panel 94 is installed on the upper left of the seat frame 91, and is preferably made of transparent acrylic material for easy observation by workers. It can not only observe the rice seedling rowing and tassel cutting situation of the pulling and tassel cutting device 5 at any time, but also effectively prevent dust, tassel leaves and other debris from flying to the picking device 9 and affecting the workers' operations.

[0142] Before harvesting, the clamping device 4 is first lowered to drive the pulling and cutting device 5 to be lifted and the lateral conveying device 8 is lowered to rotate the lateral conveyor belt 88. During harvesting, the radish tassels are first gathered by the tassel-supporting device 6 and enter the clamping device 4 to be clamped and transported to the pulling and cutting device 5. Then, the clamping mechanism 41 is connected to the pulling and cutting device 5. The pulling and cutting device 5 can be divided into two layers, the upper layer of the seedling arrangement mechanism 54 is mainly used for seedling arrangement, and the lower layer of the seedling arrangement mechanism 52 is mainly used for preparatory work for cutting. As the radish tassels are cut by the tassel cutting mechanism 53, the radish falls to the transverse conveyor belt 38 of the transverse conveying device 3. At the same time, it is manually screened and sorted by the picking device 9. The qualified radishes are transported to the accompanying collection device through the lateral conveying device 8.

[0143] When the present invention is harvesting, the root fruits are first gathered to the supporting device by the tassel-supporting device 6, and at the same time, the digging device breaks the planting ridge surface, and the root fruits are transported to the pulling and cutting device 5 by the clamping device 4, and the tassels are separated from the root fruits and dropped to the transverse conveying device 3. After manual screening and sorting, the root fruits are lifted and loaded onto the vehicle by the lateral conveying device 8. The tassel-supporting device 6 has a better tassel-gathering effect by setting an appropriate inclination angle with the ridge surface and an inclination angle of the finger of the tassel-supporting belt 617; the preferred inclination angle range of the longitudinal tassel-supporting mechanism 62 is between 75° and 90°, and the optimal inclination value should be appropriately adjusted according to different planting agronomy; the preferred inclination angle range of the transverse tassel-supporting mechanism 61 is between 64° and 90°, and the optimal inclination value should be adjusted according to different ridge surface shapes. The angle of the digging shovel 42 allows the tassels to just enter the clamping belt of the clamping device 4 during the excavation process. The clamping device 4 can automatically adjust the depth limit height according to the depth of the ridge through the depth-limiting oil cylinder control. By simulating and calculating the weight of the soil above the digging shovel 42, the range of the digging shovel 42 entry angle is preferably between 17 and 22 degrees, and the optimal value can be appropriately adjusted according to the soil conditions in different regions. The pulling and cutting device 5 and the clamping device 4 are close to each other, so that the clamping belt 418 can smoothly transfer the clamped tassels to the vine belt 522, forming an effective connection and preventing the roots and fruits from falling or colliding at the connection. The use of a hydraulic continuously variable speed crawler chassis, hydraulic contouring depth control, two-way gathering upright tassel feeding, shovel-type ridge breaking and drag reduction excavation, flexible tassel clamping, and active conveying pulling and cutting can greatly improve the efficiency of white radish harvesting, reduce the fruit damage rate, and save labor costs. It can be widely used in white radish harvesting operations in plains and hilly areas, solving the problem of mechanized white radish harvesting.

[0144] Of course, the present invention may have many other embodiments.
