TECHNICAL FIELD

[0001] The present application relates to the field of transplanting equipment, in particular to a straight-insertion type mechanized bare seedling film transplanting device and method. BACKGROUND

[0002] Taking sweet potato bare seedling film transplanting as an example, at present, the sweet potato film transplanting work has gradually been replaced by automatic or semi-automatic machines from the traditional manual complex operation. Such transplanting machines are mainly of the pincer type, chain type and duckbill type. Due to the particularity of the principle of the mechanized transplanting device and the complex agronomic requirements of sweet potato transplanting, the two seedling clamping mechanisms of the transplanting device need to take and place sweet potato seedlings due to the particularity of the structure, which can easily cause the film opening to be too large. Moreover, due to the disturbance of the soil, the posture of the sweet potato seedling after transplanting is affected, and the movement range of the mechanism is too large, which makes the soil backfilling effect after transplanting unsatisfactory. Therefore, it is difficult to guarantee the quality of sweet potato seedling transplanting when using the pincer type, chain type and duckbill type. SUMMARY

[0003] In view of the deficiencies of the prior art, the purpose of the present application is to provide a straight-insertion type mechanized bare seedling film transplanting device and method, which can solve the problems of large film opening and poor soil backfilling effect on the basis of meeting the agronomic requirements of the posture of the bare seedling after transplanting.

[0004] In order to achieve the above-mentioned purpose, the present application is realized by the following technical scheme:

[0005] In the first aspect, the embodiments of the present application provide a straight-insertion type mechanized bare seedling film transplanting device, which comprises a seedling inserting assembly, the seedling inserting assembly comprises a seedling inserting and a pull rod mechanism, the seedling inserting is connected with a driving assembly through the pull rod mechanism, and a reset spring assembly is installed between the driving assembly and the pull rod mechanism.

[0006] The driving assembly is used to make the seedling inserting produce a cyclic reciprocating transplanting action along a single longitudinal plane, so as to form a boat-shaped bare seedling transplanting.

[0007] As a further implementation manner, the seedling inserting comprises a seedling inserting main body and a fork part located at the end of the seedling inserting main body, and the seedling inserting main body is in the shape of a circular arc.

[0008] As a further implementation manner, the pull rod mechanism comprises a pull rod and an inclined pull rod, one end of the pull rod and the inclined pull rod is detachably connected with the seedling inserting, the other end of the pull rod is connected with the driving assembly, and the other end of the inclined pull rod is connected to the pull rod at a set position.

[0009] As a further implementation manner, the reset spring assembly comprises a fixed plate, the fixed plate is provided with a sliding cooperation part, the sliding cooperation part is slidably connected with a sliding block, a first spring is connected between the sliding block and one end of the fixed plate, and a second spring is connected between the sliding block and the pull rod.

[0010] As a further implementation, the sliding block and the mating end of the sliding fitting part are installed with a bearing.

[0011] As a further implementation, the sliding fitting part has a set inclination angle with the vertical normal line.

[0012] As a further implementation, the driving assembly comprises a gear box and a transmission mechanism installed in the gear box, and the transmission mechanism is connected with the pull rod mechanism.

[0013] As a further implementation, the transmission mechanism comprises a main transmission shaft and a secondary transmission shaft, the main transmission shaft is installed with a non-full-tooth driving gear, the secondary transmission shaft is installed with a full-tooth driven gear, and the non-full-tooth driving gear is matched with the full-tooth driven gear; one end of the main transmission shaft is installed with a sprocket.

[0014] In the second aspect, the embodiments of the present application also provide a direct insertion type mechanized bare seedling film up-transplanting method, which adopts the transplanting device and comprises the following steps:

[0015] The counterclockwise movement of the non-full-tooth driving gear drives the clockwise movement of the full-tooth driven gear, thereby driving the seedling inserter to insert the bare seedling into the soil in a clockwise direction; when the non-full-tooth driving gear rotates one round, the device completes one working cycle; when the teeth of the non-full-tooth driving gear are engaged with the full-tooth driven gear, the seedling inserter realizes the clockwise transplanting action; when the non-full-tooth driving gear is not engaged with the full-tooth driven gear, the seedling inserter is pulled back to the original position by the reset spring assembly to complete one working cycle.

[0016] The present application has the following advantages:

DETAILED DESCRIPTION

[0027] Example One:

[0028] In a typical embodiment of the present disclosure, as shown in Figure 1 , a direct insertion type mechanized bare seedling film transplanting device is given.

[0029] In order to solve the problems of large film opening and poor soil backfilling effect on the basis of meeting the agricultural requirements of the posture of the bare seedling after transplanting, the present embodiment provides a direct insertion type mechanized bare seedling film transplanting device, which uses a mechanized way to replace manual bare seedling planting, thereby improving the quality of bare seedling transplanting.

[0030] In the following, the above-mentioned direct insertion type mechanized bare seedling film transplanting device will be described in detail in combination with the drawings.

[0031] AsFigure 1 As shown, the direct-insertion mechanized bare seedling transplanting device includes a seedling insertion assembly 1, a return spring assembly 2, and a drive assembly. The return spring assembly 2 is connected between the seedling insertion assembly 1 and the drive assembly.

[0032] Specifically, such as Figure 2 As shown, the seedling propagation assembly 1 includes a seedling insert 101 and a pull rod mechanism, wherein the pull rod mechanism includes a pull rod 102 and a diagonal pull rod 103, and the seedling propagation assembly 1 can be cut from a steel plate.

[0033] The seedling insert 101 includes a main body and a forked part connected to one end of the main body. The main body is arc-shaped to meet the agronomic requirements of "boat-bottom shaped" bare seedling transplanting. In this embodiment, the trajectory of the seedling insert 101 in the soil is a quarter-circle (90°±5°) arc (the lowest point of this arc, i.e., the lowest point of the bare seedling, is 10±2cm away from the ground). When the device is actually working on the transplanter, the transplanting trajectory of the seedling insert 101 is a combination of a quarter-circle arc with a diameter of a circle and linear motion, and the overall trajectory meets the agronomic requirements of "boat-bottom shaped" bare seedling transplanting.

[0034] The end of the seedling cutting body away from the fork has multiple through holes to provide different installation positions for the tie rod 102 and the diagonal tie rod 103; the tie rod 102 also has multiple through holes along its length. One end of the tie rod 102 is connected to the corresponding through hole of the seedling cutting body, and one end of the diagonal tie rod 103 is installed close to the other end of the seedling cutting body; the other end of the diagonal tie rod 103 is connected to the corresponding through hole of the tie rod 102.

[0035] By setting through holes on the seedling insert body and the pull rod 102, the connection positions of the corresponding components can be changed, thereby realizing different planting trajectories and planting depths of bare seedlings; the through holes on the pull rod 102 also provide different installation points for the fixing bolts 206 in the reset spring assembly 2.

[0036] In this embodiment, the connection between the pull rod 102, the inclined pull rod 103 and the seedling insert body, as well as the connection between the pull rod 102 and the inclined pull rod 103, all adopt the method of pin connection and cotter pin locking.

[0037] like Figure 3 As shown, the reset spring assembly 2 includes a fixed plate 201, a slider 204, a sliding mating part 207, a spring, etc.; the fixed plate 201 is detachably connected to the end cover 302 of the gearbox 3, and with the working end of the seedling 101 as the front side, the fixed plate 201 is located on the rear side of the seedling 101.

[0038] In order to make the structure compact while being able to play a connecting function, the fixed plate 201 of the embodiment is provided in an L shape. The fixed plate 201 is provided with a sliding fitting part 207, which is in sliding connection with the sliding block 204, that is, the sliding block 204 can move relative to the sliding fitting part 207. In the embodiment, the sliding fitting part 207 can be a guide rail or a sliding groove, as long as the movement requirement of the sliding block 204 can be met.

[0039] Since the reset spring assembly 2 can reset the seedling 101, in order to effectively reduce the adverse vibration of the spring when rebounding, a segmented spring is adopted, the first fixed point of the segmented spring is the top end of the fixed plate 201, and the second fixed point is at one end of the pull rod 102 close to the gear box 3, and the second fixed point is provided with a fixing bolt 206; during actual work, the installation position of the fixing bolt 206 can be adjusted as needed.

[0040] Specifically, the first spring 203 is connected between the sliding block 204 and the top end of the fixed plate 201, and the second spring 205 is connected between the sliding block 204 and the fixing bolt 206, so as to form a segmented spring through the first spring 203 and the second spring 205. One first spring 203 is arranged on each side of the fixed plate 201, that is, the first springs 203 are symmetrically arranged relative to the fixed plate 201; at least one second spring 205 is arranged on one side of the fixed plate 201 to meet the reset requirement. In the embodiment, the second spring 205 is arranged on one side, which meets the reset requirement; it can be understood that in other embodiments, the second spring 205 can also be arranged on both sides of the fixed plate 201.

[0041] The sliding fitting part 207 is provided in an inclined manner, and the included angle between the sliding fitting part 207 and the vertical normal line is an acute angle, so that the spring can avoid interference with the gear box 3 during work. In the embodiment, the included angle between the sliding fitting part 207 and the vertical normal line is 10°±5°.

[0042] The cooperating end of the sliding block 204 and the sliding fitting part 207 is provided with a bearing 202, so that the reset spring response can be more timely during work.

[0043] The driving assembly includes a gear box 3 and a transmission mechanism 4 installed in the gear box 3, as shown in Figure 4 The gear box 3 includes a box body 301 and an end cover 302 installed on the outside of the box body 301, and the gear box 3 is used to provide an installation position for other components of the transplanting device. In addition, the gear box 3 is also provided with multiple bolt installation fixing points on the outside, so that the transplanting device can be installed on a transplanting machine or other machines.

[0044] As shown in Figure 5As shown, the transmission mechanism 4 includes a main transmission shaft 402, a secondary transmission shaft 404, a non-full-tooth driving gear 406, a full-tooth driven gear 405, and the like, the non-full-tooth driving gear 406 is installed on the main transmission shaft 402, the full-tooth driven gear 405 is installed on the secondary transmission shaft 404, and the full-tooth driven gear 405 can be engaged with the teeth of the non-full-tooth driving gear 406.

[0045] The main transmission shaft 402 has a sprocket 401 installed at one end, the secondary transmission shaft 404 is connected to a pull rod mechanism, and the entire transmission assembly 4 is fixed to the gear box 3 by four bearings 403. The external machinery transmits rotary motion to the sprocket 401 through chain transmission, and the power transmission route is sprocket 401-main transmission shaft 402-non-full-tooth driving gear 406-full-tooth driven gear 405-seedling inserting assembly 1.

[0046] Due to the special structure design of the device, compared with other types of transplanting devices such as clamp type and chain clamp type, the device has the advantages of small membrane breaking and port opening, small soil disturbance, and good covering effect during the working process, because the seedling inserting device 101 only moves in a single longitudinal plane without transverse movement during transplanting into the soil, and only the narrow part of the seedling inserting device moves in the soil during the transplanting process.

[0047] When the device only performs the transplanting action without forward movement, the movement trajectory of the seedling inserting device 101 in the soil is a quarter (90°±5°) of a circle with a diameter of 400mm (the diameter can be selected according to actual requirements), and the lowest point of the bare seedling is 10±2cm away from the ground. When the device is actually working on the transplanting machine, the transplanting trajectory of the seedling inserting device is a quarter of a circle with a diameter of 400mm combined with straight line movement, and the overall trajectory conforms to the "boat bottom shape" of the bare seedling transplanting agronomy requirement.

[0048] Taking sweet potato film transplanting as an example, during operation, the transplanting device of the embodiment is installed and fixed to the rear of the bare seedling conveying assembly of the transplanting machine, the seedling inserting device 101 is placed above the sweet potato seedlings on the seedling placing plate, the entire transplanting device and the bare seedling conveying assembly are placed on the ridge, and the power is input to the outer sprocket of the transplanting device through the chain sprocket of the transplanting machine. After adjusting the posture of the transplanting device, the whole machine starts to work, and the device can effectively realize the "boat bottom shape" of the sweet potato seedlings in the soil, and meet the complex planting agronomy requirements of the sweet potato seedlings.

[0049] Embodiment two:

[0050] The embodiment provides a straight inserting type mechanized bare seedling film transplanting method, which adopts the transplanting device of embodiment one, and includes:

[0051] When the device works, the device is installed and fixed to the transplanting machine, for example,Figure 6 As shown, the transplanting machine transmits power to the sprocket 401 through chain transmission, and the sprocket 401 transmits power to the non-full tooth driving gear 406 through the main transmission shaft 402, the non-full tooth driving gear 406 is engaged with the full tooth driven gear 405, and the seedling inserting assembly 1 is rigidly connected with the full tooth driven gear 405. The counterclockwise movement of the non-full tooth driving gear 406 drives the full tooth driven gear 405 to produce clockwise movement, thereby driving the seedling inserting 101 to insert the bare seedling into the soil clockwise.

[0052] When the non-full tooth driving gear 406 rotates one round, the device completes one working cycle, i.e. transplants one bare seedling. When the teeth of the non-full tooth driving gear 406 are engaged with the full tooth driven gear 405, the seedling inserting 101 realizes the clockwise transplanting action. When the non-full tooth driving gear 406 is not engaged with the full tooth driven gear 405, the seedling inserting assembly 1 is pulled back to the original position through the reset spring assembly 2 to complete one working cycle. The seedling inserting assembly 1 and the full tooth driven gear 405 wait for the next engagement, i.e. the next working cycle, at the original position.

[0053] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
