Description

 Description: A single-plate double-belt wide and narrow row transplanter

 [0001] The present invention relates to agricultural machinery equipment, and more particularly to a rice transplanter.

 Background technique

[0002] Traditional rice cultivation generally adopts the method of planting with equal spacing. However, this method of inserting plants is bound to have a problem of shading between plants and plants, which is unfavorable for ventilation and light transmission, and the ventilation and light transmittance of rice is direct. Affect the yield of rice and the prevention and control of pests and diseases. At present, wide and narrow row transplanting methods have been widely used. It is a rice high-yield cultivation technique cultivated with narrow row spacing and wide row spacing. The cultivation method can not only ensure the reasonable number of holes per unit area, but also has the advantages of reasonable distribution of plant population, good ventilation and light transmission performance, and high photosynthesis rate. Therefore, the yield level is high, which is one of the cultivation methods frequently selected for high-yield research. At the same time, due to the enhanced ventilation and light transmission, the humidity between the rice plants is reduced, which can reduce the pests and diseases to a certain extent, and finally achieve the goal of high yield and income. In order to meet the requirements of this agronomy, people have also designed a variety of wide and narrow rice transplanters. For example, the Chinese patent of CN10193342 discloses a helical gear transmission wide and narrow row transplanter. A set of staggered helical gears are arranged in the left and right gear boxes of the same structure. The planetary gears and the intermediate tilting gears are a pair of meshing crossed helical gears, so that the planetary shaft and the gear box are inclined, thereby being fixed to the planet. The planting arm of the shaft is tilted with the gear box; the moving plane of the planting arm is no longer parallel with the plane of rotation of the gear box, but is moved spatially to form a working path of the space transplanting; the needle moves from the position of the picking position to the pushing At the point position, the cusp point produces a lateral displacement, that is, a displacement perpendicular to the advancing direction of the machine, so that the seedling point is laterally shifted to the left or right relative to the position of the picking point, and the spacing of the inserted raft is formed under the premise of the existing slanting equidistant distribution. The wide and narrow rows of agronomic requirements are distributed. This structure can be used in the seedling table of the existing transplanter of the equidistant transplanting, and the wide and narrow row can be realized. However, if the lateral displacement caused by the tip of the needle is too large, that is, the angle of inclination of the needle is too large, The damage caused by the picking of the picking needle is too large; if the lateral displacement caused by the tip of the needle is too small, that is, the angle of inclination of the needle is too small, the variation of the spacing will be small, and the agronomy of the wide and narrow row will not be achieved. purpose. To solve this problem, there is also a technical solution, such as the Chinese patent of CN10177954, which discloses a wide and narrow rice transplanter, which is characterized in that it comprises a box, a plug-in mechanism, and a transfer box mechanism. , rack, suspension frame and power running device, 秧 The box can be laterally moved left and right on the frame by the moving box mechanism; the utility model is characterized in that: the spacing between the seedling removing mechanisms of the adding and inserting mechanism is arranged at intervals of a wide row width and a narrow row width; It is divided into a plurality of rug blanket placing units in a horizontal direction, and there is a space between the unit and the unit, and the unit is provided with a rug blanket position, the width of which is twice the width of the narrow line; each unit is provided with two spaces A narrow row width seedling insertion mechanism. In the technical solution, the setting of the insertion mechanism of the two seedlings of each unit is inevitably, the first one is taken from the foremost end of the rug blanket, and the second one is taken from the middle of the rug blanket, this point is taken. As can be seen from the description, this makes the insertion of the tamper by the technical solution, the narrow line of which is necessarily half the width of the carpet unit, and the existing standard rug, for example, has a width of 28 CM, and the narrow line width is realized. It is 14CM. However, current agronomic studies have shown that the width of this narrow line is too dense, which will affect the growth of rice, and the narrow line width should be 16-18CM. Therefore, to achieve this width, 32-36CM should be cultivated. Wide carpet seedlings, which obviously requires a comprehensive renovation of the existing carpet seedling cultivation equipment, resulting in a great waste. This is also an important reason why the technical solution has not been actually promoted.

 technical problem

 [0003] The invention mainly solves the technical problem that the seedling damage of the wide and narrow row transplanter existing in the prior art is serious, and it is difficult to adapt to the width of the existing carpet seedling, etc., and provides an existing one that can protect the seedlings by using the existing one. The carpet seedling cultivation equipment realizes the single-plate double-plant wide and narrow row transplanter which meets the agronomic requirements in the case of the standard carpet seedling.

 Problem solution

 Technical solution

[0004] The above technical problem of the present invention is mainly solved by the following technical solutions: A single-plate double-plant wide and narrow row transplanter, comprising a vehicle body, a seedling platform and a planting mechanism, wherein the seedlings include several The seedling board, the planting mechanism is composed of a driving box and a rotating box, each of which is provided with a planting arm, and the planting arm is provided with a plugging claw, which is characterized in that between the seedling board and the seedling board There is a vacancy position, and each seedling plate is provided with two boring positions, and each of the squatting positions is correspondingly provided with the rotary box and the corresponding insertion arm and the insertion claw, and the spacing between the two squatting positions is the seedling board. One-half of the width of the carpet can be placed, and the circular trajectory circles of the two rotary boxes corresponding to the same seedling plate form an angle with each other, so that the insertion point of the left insertion claw is opposite to the corresponding extraction point. Offset to the left by 0-2CM; the insertion point of the right insertion claw is offset to the right by 0-2CM with respect to its corresponding extraction point, and the left and right sides of the insertion claw are offset from the extraction point to the insertion point by a total of 2- 4CM. this invention The trajectory circle of the rotary box refers to the trajectory of the point where the point of the non-slewing center is taken on the rotary box. In the technical solution, the circular trajectory circles of the two rotating boxes corresponding to the same seedling plate form an angle with each other, so that the insertion point is not directly under the picking point, and the offset occurs. With this technical setting, the corresponding two insertion points are spaced more than the corresponding two extraction points. Since the two insertion points here are exactly narrow lines, the offset distance is 0-2CM, and the two are offset to the sides respectively, so the actual spacing becomes 2-4CM, so that it achieves narrow lines. The width is properly enlarged, and the seedlings are not damaged because the tilting angle of the claws is too large. Of course, the left and right sides, of course, as long as the total spacing is enlarged by 2-4 cm, the offset distances of the left and right claws can be different. The wide row of the present invention is obtained by the vacancies provided between the seedling plate and the seedling plate. Therefore, the present invention can realize wide and narrow row insertion which are suitable for both wide rows and narrow rows. The important significance of the technical solution is that, based on the width of the existing standard (commonly used) carpet, in the prior art, the narrow row in the wide and narrow row of insertions realized by one carpet seedling corresponding to the two insertion claws is agronomically Too narrow, and the present invention achieves a breakthrough in this point, using both the existing width of the carpet seedlings and the wide and narrow row spacing of the appropriate line spacing.

The output shaft of the drive box is generally parallel to the moving direction of the seedling table during operation. If the rotating shaft of the rotary box is not redirected in the output shaft connected to the drive box, the rotation path circle of the rotary box must be moved with the movement of the seedling table. The directions are perpendicular, and the rotation trajectories of each rotary box are also parallel to each other, and there is no angle. Therefore, the technical solution adopts a changing mechanism to make the non-parallel and different axes between the rotating shaft of the rotary box and the output shaft of the driving box have an angle, and realize the circular trajectory circle of the two corresponding rotating boxes. An angle. The angle of the angle of change of the changing mechanism determines the angle between the rotation trajectories of the two rotary boxes corresponding to the same seedling board.

[0006] Preferably, a double output driving box is disposed between two adjacent seedling plates, and one of the two sides of the double output driving box is respectively provided corresponding to the seedling plate of the side, and the left and right sides are respectively The seedling plates of the end are also respectively provided with a single output drive box, and the single output drive box is provided with a rotary box corresponding to the seed plate of the left and right ends, forming a layout of two seed boxes corresponding to two rotary boxes. The technical solution makes the rotary boxes on both sides of the double output drive box do not correspond to the same seedling plate, but respectively correspond to two adjacent seedling plates, because the two rotary boxes corresponding to the same seedling plate are located closer to each other. The space between the two is very limited and it is difficult to arrange a drive box. [0007] Preferably, the middle part of the lower end of the seedling board is provided with a carpet seedling dividing plate, and the seedling table is at the rightmost side, and the two corresponding positions of the seedling board are respectively at the most or the end of the seedling board and the carpet seedling segmentation The right side of the board. In the present invention, the two sputum positions corresponding to the same seedling plate are taken by the transplanting claws, one is taken from the left end, and the other is taken from the middle ridge, and the seedlings are moved to the left. The position moves to the right relative to the seedling table until the picking point on the left reaches the middle of the seedling board, and the picking point on the right side reaches the far right side of the seedling board, this is, in theory, the left side is the corresponding point. The last seedling in the first half of the seedling, but if the seedlings are not bound by any of the left and right sides, the seedlings are easy to fall, so that the transplanting claws can not get the seedlings. Similarly, when the seedlings are Moving 左 from left to right, that is, taking the 秧 point from the right to the left relative to the seedling stage, and the right side taking the 秧 point to the last one is also the same. Therefore, in the technical solution, a carpet seedling dividing plate is arranged at the lower end of the middle portion of the seedling plate, and during the downward movement of the carpet seedling, the carpet seedling is formed and divided, and the restraining effect on the seedlings on both sides is achieved.

 [0008] Preferably, the carpet seed dividing plate comprises a bottom plate for fixing the same on the seedling plate, and a dividing plate perpendicular to the bottom plate, wherein the dividing plate end has a sharp corner and is attached to the fixing plate. The lower end is lifted up to form an obliquely upward cutting edge. The cutting edge has a good cutting action on the carpet seedling.

 [0009] Preferably, the width of the seedling board can be 28CM, and the spacing between the two picking points corresponding to the same seedling board is 14CM, that is, the spacing of the picking points of the two transplanting jaws corresponding to the same seedling board. It is 14CM. In this technical solution, the seedlings of the seedling board can be placed at 28CM, which is the most widely promoted carpet seedling size. The existing seedling raising equipments are all of this size, and the insertion point is shifted relative to the picking point. The seedling spacing of -18CM is a reasonable narrow row width in the wide and narrow row transplanting technology. This technical scheme effectively realizes that two single-row 28CM carpet seedlings complete two rows of transplanting, and the spacing is larger than 1/2 of the width of the carpet seedling, which is reasonable. 16-18CM. Moreover, since the lateral displacement distance of the single insertion claw from the seedling to the insertion is small, the inclination angle of the phase to the seedling is small, and no substantial damage is caused to the seedling.
