Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rice transplanter seedling box structure, and particularly relates to a transplanter side arc rotary seedling box capable of reducing the distance between transplanted seedlings and a ridge side. BACKGROUND

[0002] A transplanter is a kind of agricultural machinery for transplanting rice seedlings into a rice field. When planting, a mechanical claw takes a number of rice seedlings from a seedbed and plants them into the soil in the field. The components of the transplanting part of various transplanters are basically the same: a manual transplanter is composed of a seedling box, a seedling separating mechanism, a frame and a float (boat plate), and a self-propelled motorized transplanter is further provided with a power drive, a walking device, a seedling feeding mechanism and other parts. The main function of the seedling box is to carry seedlings and cooperate with the seedling feeding mechanism and the seedling separating mechanism to complete the seedling feeding and separating operations. The seedling box is mainly composed of a box body, a box frame, a seedling door (including a seedling curtain) and a seedling brush. Under the action of a transverse seedling box moving mechanism, the seedling box moves transversely, so that the seedlings move to the seedling door to cooperate with the seedling taking device to take seedlings regularly and plant them. The seedling separating mechanism is the main working part of the rice transplanter, which is composed of a seedling taking device, a driving mechanism and a trajectory control mechanism. The seedling taking device is driven by the driving mechanism and controlled by the trajectory control mechanism to take a certain number of seedlings from the seedling box according to a certain trajectory and then plant them into the soil, and then returns to the original position to start the next cycle of operation.

[0003] The seedling box of the current transplanter is linear, that is, the seedling taking device takes the seedlings arranged transversely during the transverse movement of the seedling box. Thus, when the seedling box slides to the side of the ridge for transplanting, the seedling box must be 30 cm away from the ridge, otherwise the seedling box will be damaged by scraping the ridge. This makes the transplanted seedlings 30 cm away from the ridge, which causes waste of the field, and manual replanting is required, which wastes labor.

[0004] Therefore, based on the above technical problems, the technical personnel in the field urgently need to develop a transplanter side arc rotary seedling box capable of reducing the distance between transplanted seedlings and a ridge side. SUMMARY

[0005] The present application aims to provide a transplanter side arc rotary seedling box capable of reducing the distance between transplanted seedlings and a ridge side to solve the above problems.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0008] The arc-shaped seedling box is rotatably installed on the side of the seedling transplanter box frame adjacent to the transverse seedling box to be close to the ridge for seedling transplanting.

[0009] The seedling lowering mechanism is arranged on the arc-shaped seedling box to drive the seedlings to move downward to the seedling transplanter gate part for the seedling taker to take and transplant the seedlings.

[0010] The rotation driving mechanism is arranged on the arc-shaped seedling box to drive the arc-shaped seedling box to rotate, so that the seedling transplanter gate part moves horizontally relative to the seedlings horizontally distributed on the arc-shaped seedling box, and the seedling taker continuously takes the seedlings horizontally distributed on the arc-shaped seedling box.

[0011] Further, the seedling lowering mechanism includes a seedling lowering belt, and an opening is arranged on the arc-shaped seedling box to install the seedling lowering belt. The seedling lowering belt is in a closed ring shape, and the two ends are supported and tensioned by rollers. The seedlings are driven to move by the friction force through the rotation of the seedling lowering belt.

[0012] Further, two groups of the seedling lowering belts are arranged transversely on the arc-shaped seedling box.

[0013] Further, a seedling lowering motor is arranged on the back side of the arc-shaped seedling box. The seedling lowering motor drives the rollers supporting the seedling lowering belt to rotate to drive the seedling lowering belt to rotate.

[0014] Further, rotary supports are arranged on the upper and lower ends of the front side of the arc-shaped seedling box. The rotary supports are rotatably connected to the seedling transplanter box frame through the rotation shafts.

[0015] Further, when the arc-shaped seedling box rotates, the seedlings horizontally distributed on the arc-shaped seedling box are always located above the seedling transplanter gate part and the seedling taker.

[0016] Further, the rotation driving mechanism includes a passive rotary arc-shaped rack arranged on the lower end of the back side of the arc-shaped seedling box and a linkage driving gear set. The linkage driving gear set is engaged with the passive rotary arc-shaped rack to drive the arc-shaped seedling box to rotate.

[0017] Further, the linkage driving gear set drives the passive rotary arc-shaped rack to rotate by taking the transverse seedling box transverse output shaft of the seedling transplanter as the power source.

[0018] Further, the linkage driving gear set comprises a transmission rack and a speed increasing gear box, the transmission rack is connected with the transverse seedling box transverse output shaft to drive the transmission rack to move horizontally, the speed increasing gear box is arranged on the back side of the arc-shaped seedling box, the transmission rack is engaged with the input end of the speed increasing gear box, and the speed increasing gear box is engaged with the passive rotating arc-shaped rack.

[0019] Further, the arc-shaped seedling box moves synchronously with the transverse seedling box.

[0020] In the above technical solution, the present application provides a rice transplanter side arc-shaped rotating seedling box for reducing the distance between seedlings and the ridge side, which has the following beneficial effects:

[0021] The side of the present application close to the ridge of the rice transplanter is provided with a rotating arc-shaped seedling box, which is an arc-shaped and rotatable seedling box, so that the seedlings arranged horizontally are moved to the seedling door and the seedling taking device in turn in a rotating mode, instead of being moved by the transverse seedling box, and the moving distance is 15 cm shorter than that of the transverse seedling box. The distance between the seedlings and the ridge is just appropriate, and the field waste and manual operation are reduced. BRIEF DESCRIPTION OF DRAWINGS

[0033] In order to make the skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0034] Please refer to Figures 1-8 A arc-shaped rotating seedling box of the rice transplanter provided by the embodiment of the present application, the prior art of the rice transplanter includes a transplanter box frame 1, the transplanter box frame 1 is provided with a transverse seedling box 2 for carrying seedlings, the transplanter box frame 1 is used to support the transverse seedling box 2 on the rice transplanter, the transverse seedling box 2 moves horizontally, so that the seedlings move to the seedling door to cooperate with the regular seedling taking of the seedling taker, further comprising:

[0035] An arc-shaped seedling box 3, the inner arc surface of the front side of the arc-shaped seedling box 3 is used to carry seedlings, the arc-shaped seedling box 3 is rotatably installed on the transplanter box frame 1 at the side position adjacent to the transverse seedling box 2 to be close to the ridge for transplanting, specifically, at the side close to the ridge, the arc-shaped seedling box 3 sends seedlings in a rotating manner instead of the transverse seedling box 2 sending seedlings in a horizontal moving manner, so that the linear distance required for the rotating movement of the arc-shaped seedling box 3 is about 15 cm, which is 15 cm shorter than the movement distance of the transverse seedling box 2 moving horizontally, so that the rice transplanter can work at a distance of 15 cm from the ridge when transplanting, wherein the setting position of the arc-shaped seedling box 3 can be located on the left side of the transverse seedling box 2 according to specific use requirements, or can be located on the right side of the transverse seedling box 2, or can be located on both left and right sides of the transverse seedling box 2;

[0036] The seedling lowering mechanism is arranged at a position of the arc-shaped seedling box 3 for carrying seedlings to drive the seedlings to move downward to the seedling door part of the rice transplanter to be taken by the seedling taker, so that the seedling taker of the rice transplanter continuously takes the seedlings horizontally distributed on the arc surface after taking a row of seedlings distributed transversely.

[0037] The rotating driving mechanism is arranged on the arc-shaped seedling box 3 to drive the arc-shaped seedling box 3 to rotate, so that the seedling door part of the rice transplanter moves horizontally relative to the seedlings transversely distributed on the arc surface of the arc-shaped seedling box 3, so that the seedling taker continuously takes the seedlings horizontally distributed on the arc surface.

[0038] Specifically, after the arc-shaped seedling box 3 completes the seedling rotation and delivery, the seedling lowering switch is powered on, the seedling lowering motor in the seedling lowering mechanism works to drive the seedling lowering belt to complete the seedling lowering work. The arc-shaped seedling box delivers seedlings again, and the arc-shaped seedling box 3 works in this way repeatedly.

[0039] Further, the seedling lowering mechanism includes the seedling lowering belt 4, and the arc-shaped seedling box 3 is provided with an opening 5 for installing the seedling lowering belt 4, so that the front side of the seedling lowering belt 4 protrudes from the front side of the arc-shaped seedling box 3 to drive the seedlings to move. The seedling lowering belt 4 is in the form of a closed ring, and the two ends are supported and tensioned by roller shafts to form a vertical length in the same direction as the arc-shaped seedling box 3. The seedlings are driven to move by the friction force through the rotation of the seedling lowering belt 4.

[0040] Further, two groups of seedling lowering belts 4 are arranged transversely on the arc-shaped seedling box 3 to expand the area that can contact the seedlings and adapt to the arc shape of the arc-shaped seedling box 3 to better drive the seedlings to move downward.

[0041] Further, the arc-shaped seedling box 3 is provided with a seedling lowering motor 6 at the back side, and the seedling lowering motor 6 drives the roller shafts supporting the seedling lowering belt 4 to rotate to drive the seedling lowering belt 4 to rotate.

[0042] Further, the arc-shaped seedling box 3 is provided with rotating supports 7 at the upper and lower ends of the front side, and the rotating supports 7 are rotatably connected to the rice transplanter box frame 1 through rotating shafts. The two groups of rotating supports 7 are used to stably support the rotation of the arc-shaped seedling box 3. A separate support for installing the rotating supports 7 can be arranged on the rice transplanter box frame 1 to better arrange the arc-shaped seedling box 3 adjacent to the transverse seedling box 2.

[0043] Further, when the arc-shaped seedling box 3 rotates, the seedlings horizontally distributed in the arc surface on the arc-shaped seedling box 3 are always located above the seedling door part of the rice transplanter and the seedling taker to realize the continuous seedling taking of the seedling taker during the rotation of the arc-shaped seedling box 3.

[0044] Further, the rotating driving mechanism comprises a passive rotating arc-shaped rack 8 arranged at the lower end of the back side of the arc-shaped seedling box 3 and a linkage driving gear set, the linkage driving gear set is engaged with the passive rotating arc-shaped rack 8 to drive the rotation of the arc-shaped seedling box 3, the passive rotating arc-shaped rack 8 is equivalent to a transmission structure, and the transmission is achieved through gear engagement to drive the rotation of the arc-shaped seedling box 3.

[0045] Further, the linkage driving gear set is driven to rotate by the transverse seedling box 2 transverse output shaft of the rice transplanter as a power source, so that the arc-shaped seedling box 3 and the transverse seedling box 2 use a common power source to facilitate consistent operation.

[0046] Further, the linkage driving gear set comprises a transmission rack 9 and a speed increasing gear box 10, the transmission rack 9 is connected with the transverse output shaft of the transverse seedling box 2 to drive the horizontal movement of the transmission rack 9, that is, the transmission rack 9 moves synchronously with the transverse output shaft of the transverse seedling box 2, the speed increasing gear box 10 is arranged at the back side of the arc-shaped seedling box 3, the transmission rack 9 is engaged with the input end of the speed increasing gear box 10, and the speed increasing gear box 10 is engaged with the passive rotating arc-shaped rack 8, specifically, the speed increasing gear box 10 is a conventional gear transmission structure, the transmission rack 9 transmits the transverse force to a small radius gear in the speed increasing gear box 10 through engagement transmission, a large radius gear is arranged on the shaft of the small radius gear, the large radius gear is engaged with the passive rotating arc-shaped rack 8, the transmission is increased to the rotation speed of the arc-shaped seedling box 3, and the problem that the arc length of the arc-shaped seedling box 3 is longer than the width of the transverse seedling box 2 is solved, and the consistent operation of the arc-shaped seedling box 3 and the transverse seedling box 2 is ensured.

[0047] Further, the arc-shaped seedling box 3 and the transverse seedling box 2 are synchronously moved in the direction changing mode, so that the operation of the arc-shaped seedling box 3 and the transverse seedling box 2 is consistent, that is, the operation in the direction changing mode is consistent, and the linkage effect can be achieved.

[0048] According to the above embodiment, the linkage driving gear set is driven to rotate by the transverse output shaft of the transverse seedling box 2 of the rice transplanter as a power source, so that the arc-shaped seedling box 3 and the transverse seedling box 2 use a common power source to facilitate consistent operation, and we are not limited to using the linkage driving gear set for transmission, and the transmission mode can be various forms, such as universal joint transmission and other existing transmission forms.

[0049] Similarly, in the driving mechanism of the seedling lowering mechanism, the seedling lowering motor 6 is used to drive the rotation of the roller shaft supporting the seedling lowering belt 4 to drive the rotation of the seedling lowering belt 4, realizing the single driving mode of the seedling lowering motor 6, but a design scheme such as a linkage driving gear set can also be used to make the seedling lowering mechanism use the same power source as the seedling lowering structure on the transverse seedling box 2, and use the universal joint transmission, rack transmission or other conventional forms of electric transmission in the prior art to drive the rotation of the seedling lowering belt 4, but the above conventional transmission structure will not be described again, and only the driving mode and transmission mode of the seedling lowering mechanism and the rotating driving mechanism are described.

[0050] In summary, the seedling transplanter of the present application uses a rotating arc-shaped seedling box on the side close to the ridge, which is an arc-shaped and rotatable seedling box. The arc-shaped seedling box ensures seedling lowering and rotates to move the transversely arranged seedlings horizontally to the seedling gate and seedling taker position in turn, replacing the seedling feeding mode of the transverse seedling box. Since it is a rotating mode, the movement distance is 15 cm shorter than that of the linear transverse seedling box. The distance from the seedlings to the ridge is just right, reducing field waste and manual operation.

[0051] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is not doubtful that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
