Technical Field

[0001] This utility model relates to the field of Pinellia ternata harvesting technology, and specifically discloses a Pinellia ternata harvesting plow with adjustable digging depth. Background Technology

[0002] Pinellia ternata is a plant belonging to the genus Pinellia in the family Araceae. Its tuber is spherical, 1-2 cm in diameter, and has fibrous roots. It has 2-5 leaves, sometimes 1. The petiole is 15-20 cm long, with a sheath at the base. Within the sheath, above the sheath, or at the base of the leaf blade (petiole tip), there are bulbils 3-5 mm in diameter. These bulbils germinate on the mother plant or after falling to the ground. Seedling leaves are ovate-cordate to hastate, entire, simple, 2-3 cm long and 2-2.5 cm wide. Mature plant leaves are 3-lobed, with green lobes, pale on the back, oblong-elliptic or lanceolate, acute at both ends. The middle lobe is 3-10 cm long and 1-3 cm wide; the lateral lobes are slightly shorter. The margins are entire or have indistinct shallow wavy teeth. There are 8-10 pairs of lateral veins, thin and weak, with a dense reticulate network of fine veins and two concentric rings of veins. It is a medicinal plant with properties of drying dampness and resolving phlegm, relieving nausea and vomiting, and reducing boils when used raw.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-3 A Pinellia ternata harvesting plow with adjustable digging depth includes a cleaning box 1 with open structures at both the top and bottom. The lower end of the cleaning box 1 is provided with an adjustment mechanism, the inside of the cleaning box 1 is provided with a cleaning mechanism, and the left side of the cleaning box 1 is provided with a digging mechanism.

[0023] The adjustment mechanism includes an annular groove 2 opened on the lower end face of the cleaning box 1. A movable cylinder 3 is slidably connected inside the annular groove 2. Two symmetrically distributed screws 4 are rotatably connected to the upper end of the annular groove 2. Both screws 4 are threadedly connected to the movable cylinder 3. Multiple evenly distributed drive wheels 5 are installed at the lower end of the movable cylinder 3.

[0024] The cleaning mechanism includes a sluice 6 fixedly connected to the inner sidewalls of the front and rear sides of the cleaning box 1. A screen 7 is provided between the two sluice 6. Rollers 8 located inside the two sluice 6 are fixedly connected to the front and rear ends of the screen 7.

[0025] The excavation mechanism includes two mounting plates 9 fixedly connected to the left side wall of the cleaning box 1 and distributed front and back. A conveyor 10 is installed between the two mounting plates 9. The conveyor 10 is driven by a drive motor installed on the rear end of the cleaning box 1. A shovel plate 11 is fixedly connected to the left end of the two mounting plates 9. The right end of the shovel plate 11 extends above the conveyor 10. A rotating roller 12 is rotatably connected inside the shovel plate 11. A plurality of evenly distributed crushing push bars 13 are fixedly connected to the outer wall of the rotating roller 12.

[0026] In this embodiment: When in use, the device is moved to the harvesting point, and then the digging depth of the Pinellia harvesting plow is adjusted according to the site conditions. Specifically, the two screws 4 rotate, driving the moving cylinder 3 to move up or down. After the moving cylinder 3 moves up, the height of the cleaning box 1 decreases, and at the same time, the position of the shovel 11 moves down relative to the position of the multiple drive wheels 5, making the digging depth of the shovel 11 deeper. After the moving cylinder 3 moves down, the height of the cleaning box 1 increases, and at the same time, the position of the shovel 11 moves up relative to the position of the multiple drive wheels 5, making the digging depth of the shovel 11 shallower. Thus, the digging depth of the device is adjusted according to the site conditions to avoid damage to shallow Pinellia or missed harvesting of deep Pinellia.

[0027] After adjustment, the device is moved by multiple drive wheels 5. During the movement, the drive motor drives the conveyor 10 to operate. At the same time, the shovel 11 is inserted into the ground to shovel the soil and Pinellia ternata into the shovel 11. Then the rotating roller 12 rotates, which drives multiple crushing push bars 13 to rotate. The rotating crushing push bars 13 crush the soil and push the crushed soil and Pinellia ternata inside the soil to the conveyor 10. Then the conveyor 10 transports the soil and Pinellia ternata into the cleaning box 1, thereby excavating and transporting the soil and Pinellia ternata.

[0028] After the soil and Pinellia ternata enter the cleaning box 1, they fall onto the screen 7. The screen 7 then swings back and forth. Through the cooperation of the two chute 6 and multiple rollers 8, the screen 7 can swing smoothly, screening the soil and Pinellia ternata. After the soil is screened by the screen 7, it is backfilled to the ground through the cleaning box 1 and the moving cylinder 3. The Pinellia ternata stays on the screen 7 and is discharged through the discharge chute 26, thus cleaning the soil on the outside of the harvested Pinellia ternata. It is convenient to use.

[0029] As a technical optimization of this utility model, the outer walls of the two screws 4 are fixedly connected with the first bevel gear 14, and the inside of the cleaning box 1 is rotatably connected with the rotating shaft 15 located below the screen 7. Both ends of the rotating shaft 15 extend into the inside of the annular groove 2 and are fixedly connected with the second bevel gear 16 that meshes with the first bevel gear 14.

[0030] In this embodiment: the rotating shaft 15 rotates, and the rotating shaft 15, in conjunction with two second bevel gears 16, drives two first bevel gears 14 to rotate, and the two first bevel gears 14 drive two screws 4 to rotate.

[0031] As a technical optimization of this utility model, one of the rotating shafts of the conveyor 10 extends to the front of the cleaning box 1 and is fixedly connected to the rotating wheel 17. The front end face of the cleaning box 1 is provided with a sliding hole 18. The front end face of the screen 7 is fixedly connected with an extension rod passing through the sliding hole 18. A connecting rod 19 is movably connected between the eccentric shaft of the rotating wheel 17 and the extension rod.

[0032] In this embodiment: During the operation of the conveyor 10, the conveyor 10 drives the rotating wheel 17 to rotate through one of the rotating shafts. The rotating wheel 17, together with the connecting rod 19 and the extension rod, drives the screen 7 to sway back and forth.

[0033] As a technical optimization of this utility model, the front end of the roller 12 extends to the front of the shovel plate 11 and is fixedly connected to the first synchronous wheel 20. The other rotating shaft of the conveyor 10 extends to the front side of the front mounting plate 9 and is fixedly connected to the second synchronous wheel 21. A synchronous belt 22 is connected between the first synchronous wheel 20 and the second synchronous wheel 21.

[0034] In this embodiment: During the operation of the conveyor 10, the conveyor 10 drives the second synchronous wheel 21 to rotate through another rotating shaft. The second synchronous wheel 21, together with the synchronous belt 22, drives the first synchronous wheel 20 to rotate. The first synchronous wheel 20 drives the rotating roller 12 to rotate.

[0035] As a technical optimization of this utility model, a protective box 23 is fixedly connected to the right inner side wall of the cleaning box 1. A rotating shaft 15 passes through the protective box 23 and is rotatably connected to the protective box 23. A worm gear 24 located inside the protective box 23 is fixedly connected to the outer wall of the rotating shaft 15. A worm 25 meshing with the worm gear 24 is rotatably connected inside the protective box 23. The front end of the worm 25 extends to the front of the cleaning box 1 and is fixedly connected to a torsion block.

[0036] In this embodiment: the worm 25 is driven to rotate by a rotating torsion block, and the worm 25, in conjunction with the worm wheel 24, drives the rotating shaft 15 to rotate.

[0037] As a technical optimization of this utility model, the right side wall of the cleaning box 1 is connected to the discharge trough 26, and the right end of the screen 7 extends into the interior of the discharge trough 26.

[0038] In this embodiment, the discharge chute 26 facilitates the centralized collection of the screened Pinellia ternata.

[0039] The working principle and usage process of this utility model are as follows: When in use, the device is moved to the harvesting point, and then the digging depth of the Pinellia harvesting plow is adjusted according to the site conditions. Specifically, the worm 25 is driven to rotate by rotating the torsion block. The worm 25, in conjunction with the worm wheel 24, drives the rotating shaft 15 to rotate. The rotating shaft 15, in conjunction with the two second bevel gears 16, drives the two first bevel gears 14 to rotate. The two first bevel gears 14 drive the two screws 4 to rotate. The two screws 4 drive the moving cylinder 3 to move up or down. After the moving cylinder 3 moves up, the height of the cleaning box 1 decreases. At the same time, the position of the shovel 11 moves downward relative to the position of the multiple drive wheels 5, making the digging depth of the shovel 11 deeper. After the moving cylinder 3 moves downward, the height of the cleaning box 1 increases. At the same time, the position of the shovel 11 moves upward relative to the position of the multiple drive wheels 5, making the digging depth of the shovel 11 shallower. Thus, the digging depth of the device is adjusted according to the site conditions.

[0040] After adjustment, the device is moved by multiple drive wheels 5. During the movement, the drive motor drives the conveyor 10 to operate. At the same time, the shovel 11 is inserted into the ground to shovel the soil and Pinellia ternata into the shovel 11. Meanwhile, the conveyor 10 drives the second synchronous wheel 21 to rotate through another rotating shaft. The second synchronous wheel 21, together with the synchronous belt 22, drives the first synchronous wheel 20 to rotate. The first synchronous wheel 20 drives the rotating roller 12 to rotate. The rotating roller 12 drives multiple crushing push bars 13 to rotate. The rotating crushing push bars 13 crush the soil and push the crushed soil and Pinellia ternata inside the soil to the conveyor 10. Then, the conveyor 10 transports the soil and Pinellia ternata into the cleaning box 1, thereby excavating and transporting the soil and Pinellia ternata.

[0041] After the soil and Pinellia ternata enter the cleaning box 1, they fall onto the screen 7. Then, during the operation of the conveyor 10, the conveyor 10 drives the rotating wheel 17 to rotate through one of the rotating shafts. The rotating wheel 17, together with the connecting rod 19 and the extension rod, drives the screen 7 to swing back and forth. Through the cooperation between the two chute 6 and the multiple rollers 8, the screen 7 can swing smoothly to screen the soil and Pinellia ternata. After the soil is screened by the screen 7, it is backfilled to the ground through the cleaning box 1 and the moving cylinder 3. The Pinellia ternata stays on the screen 7 and is discharged through the discharge chute 26.
