Description

Sweet potato seedling transplanter

Technical Field

The utility model relates to the technical field of sweet potato planting machinery, in particular to a sweet potato seedling transplanting machine.

Background

China is a large agricultural country and one of the most abundant agricultural product types, wherein sweet potatoes are food crops inferior to rice, wheat and corn. The main links of sweet potato planting are: seedling arrangement breeding, tillage ridging, seedling shearing, transplanting, field management, harvesting and the like, wherein the transplanting link plays a vital role in the yield of sweet potatoes.

The sweet potato is mainly propagated asexually by adopting tuberous root, and is first cultivated and then transplanted. At present, the transplanting of sweet potatoes in China mainly takes bare seedling transplanting such as high-shearing seedling and the like as main materials, namely, seed potatoes are planted on a seedling raising bed, stem tips are sheared after the sweet potatoes grow to a certain degree, the seed potatoes are transplanted into a field, and a pot seedling transplanting mode is used as auxiliary materials. In general, when crops such as tobacco, cotton, vegetables and the like are planted, the stems of the aerial parts of seedlings are required to be upright and the rhizomes of the underground parts of seedlings are required to be less bent, but the planting of sweet potatoes has special requirements. Sweet potatoes are rooted at the nodes of seedlings buried in soil, and the insertion depth is preferably 3-4 nodes. If seedlings are planted vertically, the sweet potatoes with narrow potato forming space are crowded and grow, and the deformed melons with low yield appear in a large quantity. Therefore, the sweet potatoes are planted in a flat way, namely, seedlings are laid on soil layers 3-5 cm above the ridges in a flat way and then are watered and buried. The flat planting potato has large space and even nutrition absorption, and is beneficial to improving the yield of sweet potatoes.

In addition, the transplanting density of the seedlings needs to be correspondingly adjusted according to factors such as different soil conditions, climate conditions, seedling length, fruit size requirements and the like.

Chinese patent CN208768426U discloses a sweet potato horizontal transplanting machine, wherein the turntable is driven by a power mechanism to rotate, the turntable drives a transplanting rod to rotate together, the middle part of the transplanting rod is hinged with the turntable, the inner end of the transplanting rod forms sliding fit with an eccentric wheel, when the transplanting rod reaches the rear of a belt transmission mechanism, a fork at the outer end of the transplanting rod clamps seedlings on the belt transmission mechanism, then the seedlings are driven to rotate downwards and backwards, after the seedlings are horizontally inserted into soil, the transplanting rod is separated from the seedlings and pulled out from the soil, the transplanting rod continues to move upwards and returns to an initial state, and the transplanting rod is ready for the next transplanting. The transplanting machine can horizontally insert the roots of seedlings into soil.

However, this sweet potato horizontal transplanter has the following disadvantages: 1) When the fork heads at the outer ends of the transplanting rods horizontally insert seedlings into soil and the fork heads are pulled out of the soil, sometimes the seedlings can be pulled out of the soil along with the fork heads, so that the seedling missing condition occurs, and the later stage also needs manual seedling supplementing, which is time-consuming and labor-consuming; 2) In the single transplanting process, the fork width of the fork head of the transplanting rod is fixed, and the transplanting rod cannot adapt to seedlings with different thicknesses, so that the situation that the seedlings cannot be clamped due to the overlarge fork width or damaged due to the overlarge fork width frequently occurs; 3) In the transplanting process, the user places the seedling interval on the conveying belt according to rough estimation of the distance, due to errors of manual estimation, the possible interval of the seedling on the conveying belt is variable, the field is soft after the cultivation, the transplanting machine is easy to jolt in the advancing process, the seedling feeding is uneven, the transplanting interval is unequal, and the transplanting quality is reduced; 4) When the seedlings are placed manually, a user needs to estimate possible movement tracks of the transplanting rods and align fork heads of the transplanting rods to place the seedlings, and the operations are difficult in the actual field operation process, so that the transplanting rods can not always grasp the seedlings, and the transplanting efficiency is greatly reduced; 5) The transplanting rods extend on the rotary table along the circumferential direction, and the periphery of the rotary table can accommodate a small number of transplanting rods (only 5 as shown in fig. 2 of the patent specification), which means that the rotary table rotates for transplanting at most 5 seedlings, so that transplanting efficiency is low; 6) The transplanting machine has the advantages of more components and complex structure, and the slender, forked and bent transplanting rods are easy to damage in the actual transplanting process, so that the maintenance rate of the transplanting machine is high.

The embodiment of the application provides a sweet potato seedling transplanting machine which is used for flat planting of sweet potato seedlings.

Fig. 1 is a schematic diagram of the overall structure of a sweet potato seedling transplanting machine according to an embodiment of the application. As shown in fig. 1, the sweet potato seedling transplanting machine comprises a frame 1, travelling wheels 2, a seedling feeding mechanism 3, a seedling transplanting mechanism 4, a film covering mechanism 5, a supporting wheel 6, a storage Miao Cao, a seat 8 and a hanging mechanism 9.

The bracket 1 is used for providing a mounting framework for each component of the transplanting machine.

The road wheels 2 are installed under the frame 1 for supporting and gripping the ground to provide driving force. In order to increase friction force and facilitate grabbing ground, deeper lines are arranged on the travelling wheels 2. The travelling wheel 2, the seedling feeding mechanism 3 and the transplanting mechanism 4 are in transmission connection, such as transmission through gears and chains. In particular, two road wheels 2 may be provided, connected therebetween by a drive shaft, on which a gear is provided. The gear is connected with gears arranged in the seedling feeding mechanism 3 and the seedling transplanting mechanism 4 through chains. The travelling wheel 2, the seedling feeding mechanism 3 and the transplanting mechanism 4 can also be connected in other modes, such as belt connection and the like, and the application is not particularly limited. The transplanting machine is driven by a tractor, and the travelling wheels 2 rotate under the action of friction force with the ground to drive the seedling feeding mechanism 3 and the transplanting mechanism 4 to operate.

The seedling feeding mechanism 3 is arranged on the frame 1 and is used for conveying seedlings to the seedling transplanting mechanism 4. Fig. 2 is a schematic structural view of a seedling feeding mechanism and a single-turntable seedling transplanting mechanism according to an embodiment of the present application. As shown in fig. 2, the seedling feeding mechanism 3 includes a conveyor belt 31, seedling plates 32 provided below the conveyor belt 31, and seedling clamps 33 fixed to the conveyor belt 31 at regular intervals. The conveyor belt 31 and the placement Miao Ban 32 are inclined downward so that the output end of the conveyor belt 31, the lower edge of the placement Miao Ban 32 and the input end of the transplanting mechanism 4 cooperate with each other. The conveyor belt 31 is rotated synchronously by the driving of the traveling wheel 2 through a gear provided in the seedling feeding mechanism 3. The conveyor belt 31 may be of a link structure provided with fixing holes thereon, the seedling clamps 33 are provided with corresponding fixing holes, and the seedling clamps 33 may be fixed on the conveyor belt 31 to rotate therewith by screws passing through the fixing holes on the seedling clamps 33 and the links. The seedling clamps 33 may also be fixed to the conveyor belt 31 by other connection means such as adhesive connection, magnetic adsorption connection, etc., which are not particularly limited in the present application. Seedling clamps 33 may be made of a resilient rubber material and have a U-shape. The seedling clamp 33 may be made of other materials to form various shapes as long as it is suitable for clamping and releasing seedlings, which is not particularly limited in this application. In the transplanting process, the roots of seedlings are clamped in the seedling clamps 33 through the U-shaped openings of the seedling clamps 33, and the stems naturally lie on the seedling placing plate 32, so that the seedlings move to the input end of the transplanting mechanism 4 along with the conveying chain belt 31. The output end of the conveyor belt 31 may be further provided with a seedling feeding baffle 34 to prevent seedlings clamped in the seedling clamps 33 from continuing to move with the conveyor belt 31. The spacing between the seedling clamps 33 can be adjusted as required to adjust the transplanting spacing and control the transplanting density.

The seedling transplanting mechanism 4 is arranged on the frame 1 and matched with the seedling conveying mechanism 3, and is used for planting seedlings conveyed from the seedling conveying mechanism 3 into soil. The transplanting mechanism 4 includes a turntable 41. Fig. 3 is a schematic structural view of a turntable according to an embodiment of the present application. As shown in fig. 2 and 3, a transplanting baffle 42 is provided along a portion of the outer periphery of the turntable 41 at the input end of the transplanting mechanism 4. The transplanting baffle 42 comprises an upper arc baffle 421 and a lower arc baffle 422, a gap is formed between the upper arc baffle 421 and the lower arc baffle 422 at a certain angle to serve as a seedling inlet 43, and a seedling outlet 44 is formed at the lower end of the lower arc baffle. By adjusting the spacing between the upper and lower arcuate baffles 421 and 422, the size of the seedling inlet 43 can be varied to accommodate seedlings of different sizes. Seedlings enter the seedling inlet 43 along with the conveyor belt. The outer peripheral edge of the rotary plate 41 is uniformly provided with ratchet teeth 411. The inclined direction of the ratchet 411 is away from the traveling direction of the turntable 41 so as to catch seedlings. The interval between the ratchets 411 can be adjusted to adapt to the interval between the seedling clamps 33, and the transplanting density is adjusted. The rotary table 41 is offset from the conveyor belt 31 by a certain distance in the axial direction of the rotary table 31, so that the ratchet 411 is convenient to catch the stem of the seedling. After the seedlings are clamped, the turntable 41 continues to rotate to drive the seedlings to rotate along with the turntable. Seedlings are pulled by the turntable 41 under the restraint of the lower arc baffle, come out of the seedling outlet 44, and are then pressed into the soil by the turntable 41. As the ratchet 411 rotates to the lowest point, the seedlings are also pressed to the deepest, are separated from the ratchet 411 and left in the soil, and the ratchet 411 is rotated out of the soil and continues to rotate until the seedling inlet 43 catches the next seedling. The transplanting mechanism shown in fig. 2 comprises a turntable. Alternatively, the transplanting mechanism 4 may include two turntables to simultaneously plant two rows of sweet potato seedlings on one ridge, thereby improving transplanting efficiency. By way of example, fig. 4 is a schematic structural view of a seedling feeding mechanism and a double-turntable seedling transplanting mechanism according to an embodiment of the present application, and the seedling transplanting mechanism 4 in fig. 4 includes two turntables. The transplanting mechanism 4 may further comprise more turntables as required, and the conveyor belt 31 and the corresponding transmission structure need only be correspondingly increased, which is not particularly limited in the present application.

Fig. 5 is a schematic structural view of a film covering mechanism according to an embodiment of the present application. As shown in fig. 5, the film laminating mechanism 5 includes a film supporting rod 51, a film pressing roller 52, a ditching plate 53, a film pressing wheel 54, and a soil covering plate 55. The film support rod 51 is used for inserting a film cartridge from which the film is unwound. The film pressing roller 52 is used for pressing down the middle part of the film to attach the film to the ridge. The trenching plate 53 is used to plow a shallow trench into the soil and the film covers both edges over the shallow trench. The film pressing wheel 54 is used for pressing both edges of the film into the shallow trench. The earthing disk 55 is used to cover the thin film in the shallow trench.

The support wheels 6 are used to provide support together with the road wheels 2. Chu Miaocao 7 is used for storing seedlings in the transplanting process, and is convenient to take and place. The seat 8 is used for a user to sit during transplanting. The suspension mechanism 9 is used to suspend the transplanter to the tractor.

In the transplanting process, the transplanting machine is hung on a tractor, seedlings are placed in the seedling storage groove 7, and the film cylinder is sleeved on the film supporting rod 51. After the tractor is started, the travelling wheel 2 advances to drive the conveying chain belt 31 and the rotary table 41 to rotate. The user takes out seedlings from the storage Miao Cao 7 and puts them into the seedling feeding mechanism 3 so that the roots of the seedlings are clamped in the seedling clamps 33 and the stems are laid flat on the seedling plate 32. The seedlings enter the seedling inlet of the transplanting mechanism 4 along with the conveying chain belt 31, are dragged by the turntable 41 and are pressed into the soil. The film coating mechanism 5 then coats the soil with the film.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
