Detailed Implementation

[0026] As shown in the accompanying drawings, this embodiment provides a multi-functional cherry radish harvester, including a chassis frame 1, a mounting frame 2 on the chassis frame 1, and wheels 3 on the chassis frame 1.

[0027] A clamping device 4 is connected to the front end of the chassis frame 1, and a cherry-supporting device 5 is connected to the front end of the clamping device 4. A diversion device 6 is connected to the lower rear of the clamping device 4 on the mounting frame 2. Collection frames 7 are set on both sides of the diversion device 6. The collection frames 7 are connected to both sides of the chassis. A sowing and fertilizing device 8 is connected to the lower part of the mounting frame 2. A seed and fertilizer bin 9 is connected to the upper part of the sowing and fertilizing device 8. A furrowing device 10 is connected to the front end of the sowing and fertilizing device 8 on the chassis. A soil covering device 11 is connected to the rear end of the sowing and fertilizing device 8 on the mounting frame 2. A watering device 12 is connected to both the mounting frame 2 and the chassis frame 1 above the soil covering device 11.

[0028] The clamping device 4 includes a clamping frame 13, an upper limit plate 14, a lower limit plate 15, a synchronous pulley, a synchronous belt 16, a tension pulley 17, a torsion spring 18, and a blade 19. The clamping frame 13 is connected to the mounting frame 2. The lower limit plate 15 is connected above the clamping frame 13. The upper limit plate 14 and the lower limit plate 15 are connected by a connecting column with a space between them. A clamping drive motor 20 is mounted on the lower limit plate 15 via a motor bracket. The upper limit plate 14 and the lower limit plate 15 are rotatably connected at their front and rear ends. The step wheel, the front and rear synchronous wheels are connected by a synchronous belt 16 for synchronous transmission (a part of the synchronous belt 16 is omitted to show the inner parts). The clamping drive motor 20 is connected to one of the synchronous wheels to drive the synchronous wheel to rotate. Multiple tension wheels 17 are provided on the inner side of the synchronous wheel. Torsion springs 18 are provided on the tension wheels 17 to adjust the clamping force. Blades 19 are connected to the upper limit plate 14 and the lower limit plate 15 through blade 19 brackets to cut radish and cherry stems. The cherry support 5 is connected to the front end of the lower limit plate 15.

[0029] The synchronous pulleys include a front left pulley 21, a front right pulley 22, a rear left pulley 23, and a rear right pulley 24. The front left pulleys 21 and 22 are connected to the front end between the upper limit plate 14 and the lower limit plate 15, and the rear left pulleys 23 and 24 are connected to the rear end between the upper limit plate 14 and the lower limit plate 15, respectively. The clamping drive motor 20 is connected to either the rear right pulley 24 or the rear left pulley 23. A synchronous belt 16 is connected between the front left pulley 21 and the rear left pulley 23, and another synchronous belt 16 is connected between the front right pulley 22 and the rear right pulley 24. Each of the rear left pulleys 23 and the rear right pulley 24 is connected to a synchronous gear 25 via a flange coupling, and the two synchronous gears 25 mesh with each other.

[0030] When the clamping drive motor 20 is working, the motor shaft drives the rear right wheel 24 or the rear left wheel 23 to rotate. The rear left wheel 23 and the rear right wheel 24 rotate in opposite directions through the action of the synchronous gear 25. The two synchronous belts 16 rotate in opposite directions, driving the front left wheel 21 and the front right wheel 22 to rotate in opposite directions. The tensioning wheel 17 inside the synchronous belt 16 provides sufficient tension for the rotation of the synchronous belt 16 and each synchronous wheel.

[0031] The radish tassel gathers the radish tassels between the two synchronous belts 16. Because the gap between the two synchronous belts 16 is smaller than the radish tassels, the tensioning force of the tensioning wheel 17 squeezes the radish tassels and clamps them. Then, the radish is pulled out from front to back and from bottom to top by the two conveyor belts installed at a certain angle to the ground and the conveyor belts rotating in opposite directions at the same time.

[0032] The diversion device 6 includes a buffer plate 26, a guide block 27, and a ramp plate 28. The buffer plate 26 is mounted on the mounting frame 2 and located below and behind the clamping device 4. The guide block 27 is herringbone shaped with its pointed end facing forward. The guide block 27 and the buffer plate 26 are movably connected by a guide shaft. There are two ramp plates 28, located on both sides of the guide block 27 and connected to the buffer plate 26. The lower ends of the two ramp plates 28 are located above the two collection frames 7.

[0033] Once the clamping action is complete, the radish tops are cut off by the blade 19, separating the stems and leaves. The cut stems and leaves are scattered back into the field, while the radishes first fall onto the buffer plate 26 on the diversion device 6, and then are randomly diverted to both sides by the guide block 27, falling along the slope to the collection frames 7 on both sides, thus completing the radish pulling, top cutting, and collection.

[0034] The sowing and fertilizing device 8 includes a sowing and fertilizing frame 29, an impeller 30, a sowing groove wheel 31, a fertilizing groove wheel 32, a light shaft 33, a spring shock absorber 34, a linear guide rail 35, and a funnel 36. The light shaft 33 passes through the sowing and fertilizing frame 29 and is rotatably connected to the fertilizing frame via a flange bearing. There are two impellers 30, which are connected to both ends of the light shaft 33 via flange couplings and are located outside the sowing and fertilizing frame 29. The sowing groove wheel 31 and the fertilizing groove wheel 32 are both connected to the middle of the light shaft 33 via flange couplings and are located inside the sowing and fertilizing frame 29. Spring shock absorbers 34 are respectively installed in the middle of the outer two sides of the sowing and fertilizing frame 29. The lower end of the spring shock absorber 34 is movably connected to the sowing and fertilizing frame 29. There are two linear guide rails 35, which are respectively installed on both sides above the rear end of the sowing and fertilizing frame 29. The funnel 36 is fixed to the bottom of the sowing and fertilizing frame 29.

[0035] As the harvester moves forward, the spring shock absorber 34 applies pressure to the fertilizer frame, causing the seeding and fertilizing device 8 to exert a certain pressure on the ground. The friction force drives the impeller 30 to rotate, which in turn drives the optical shaft 33 to rotate. This, in turn, drives the seeding groove wheel 31 and fertilizer groove wheel 32 in the middle of the seeding and fertilizing device 8 to rotate. The seeds and fertilizer in the seed and fertilizer bin 9 placed above the seeding and fertilizing device 8 are evenly carried out through the grooves on the seeding groove wheel 31 and fertilizer groove wheel 32, thus achieving the falling of fertilizer and seeds.

[0036] The trenching device 10 includes a trenching shovel 37 and a front shovel arm 38. The rear end of the front shovel arm 38 is movably connected to an angle bracket and connected to the chassis frame 1 through the angle bracket. The trenching shovel 37 is connected to the front end of the front shovel arm 38. The front shovel arm 38 is provided with multiple pairs of connecting holes 39 at different heights, and the trenching shovel 37 can change its installation height by connecting to the connecting holes 39 at different heights.

[0037] By adjusting the connection position of the trenching shovel 37 on the front shovel arm 38, the trenching depth can be changed according to the trenching requirements and soil environment of different fields of radish, so as to adapt to the planting of cherry radish in different regions.

[0038] The soil covering device 11 includes a soil covering frame 40, a fixed angle bracket 41, a torsion spring 42, and soil gathering levers 43. The fixed angle bracket 41 is fixed on the mounting frame 2. The torsion spring 42 and the fixed angle bracket 41 are rotatably connected to the soil covering frame 40 by bolts. The torsion spring 42 is in partial contact with the soil covering frame 40. There are two soil gathering levers 43, which are fixed on the lower sides of the soil covering frame 40 respectively.

[0039] When the soil covering device 11 is working, the torsion spring 42 applies pressure to the soil covering machine frame 40 so that it can contact the ground, and the soil gathering blade 43 can gather the soil from both sides to the middle to complete the soil covering action.

[0040] The water spraying device 12 includes a water tank 44, a water pump 45, and a water spraying pipe 46. The water pump 45 is mounted on the mounting frame 2, and the water tank 44 is mounted on the chassis frame 1. The water pump 45 extends into the water tank 44 through the water pipe. The water spraying pipe 46 is fixed to the rear end of the chassis frame 1. The upper end of the water spraying pipe 46 is connected to the water pump 45, and the lower nozzle end of the water spraying pipe 46 is located above the soil covering device 11.

[0041] The water pump 45 draws water from the water tank 44 through the water pipe, and then sprays it onto the ground through the sprinkler pipe 46.

[0042] The upper part of the mounting frame 2 is connected to the main drive motor 47 via a motor bracket. The output end of the main drive motor 47 is connected to the rudder disk 48 via a flange connector. A steel wire rope is connected to the rudder disk 48. The steel wire rope passes through and is connected to the sowing and fertilizing device 8, the ditching device 10, and the soil covering device 11 respectively. Both ends of the steel wire rope are connected to the rudder disk 48.

[0043] The operation of the main drive motor 47 can control whether the ditching device 10, the sowing and fertilizing device 8, and the soil covering device 11 are close to the ground. When the main drive motor 47 is working, it drives the flange coupling and the rudder disc 48, which in turn drives the wire rope to tighten, and then drives the ditching device 10, the sowing and fertilizing device 8, and the soil covering device 11 to rise in height and leave the ground.

[0044] The overall working method is as follows.

[0045] When the cherry radish harvester is working, the radish tops lifter guides the fallen and misaligned radish tops to the center. Then, driven by the clamping drive motor 20, the synchronous belts 16 on both sides drive the synchronous belts 16 to move in opposite directions, clamping the radish tops while the machine moves forward. The radish is pulled out of the ground. When it reaches the blade 19, the radish tops are cut off and fall back into the field. The radish tubers fall onto the buffer plate 26 and then randomly fall to one side of the guide block 27. After passing the ramp plate 28, they finally fall into the collection frames 7 on both sides, completing the radish harvesting.

[0046] During the sowing and fertilization process: the main drive motor drives the steering disc 48, causing the wire rope to slack, allowing the furrowing shovel 37 to be inserted into the soil; the impeller 30 in the sowing and fertilization device 8 is pressed against the ground by the elastic force of the spring damper 34; the soil covering device 11 is pressed against the ground by the elastic force of the torsion spring 42. As the machine moves forward, the furrowing shovel 37 opens a furrow, and then the sowing wheel 31 and fertilization wheel 32 in the sowing and fertilization device 8, driven by the impeller 30, evenly spread fertilizer and seeds onto the ground through the funnel 36. Then, under the action of the soil covering frame 40 and the soil gathering disc 43, the soil covering device 11 gathers the soil that was pushed to both sides by the furrow opening back to the center, completely covering the seeds and fertilizer. After the soil is covered, the water pump 45 starts working, spraying water from the water tank 44 of the sprinkler device 12 onto the land through the sprinkler pipe 46, thereby completing a series of sowing and fertilizing actions such as ditching, sowing, fertilizing, covering, and watering.

[0047] It is understood that the above specific description of the present invention is only for illustrating the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of the present invention.
