Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of rice transplanter, specifically a hand-held step type rice transplanter. BACKGROUND

[0002] The rice transplanter is a kind of agricultural machinery that plants seedlings into farmland. With the development of technology, the current rice transplanter has realized mechanization, automation and intelligentization, and can adapt to the needs of different regions for rice transplanting. However, for the special agronomic problems in some areas, there is still no solution, especially for the agronomic requirements in small area and hilly seed production areas, there is still no mechanized rice transplanter to solve. The planting density of seedlings directly affects the population structure, pollination and final yield. The current hand-held step type rice transplanter is limited by the mutual constraint between mechanical structures, and the minimum row spacing of planting can only reach 25 cm. In order to realize the row spacing of 20 cm, even some machines use wide-narrow row alternate planting method, but the structure still retains the middle row spacing of 30 cm wide, which leads to poor natural pollination effect due to long distance. Some can only be realized on high-speed riding rice transplanter, but high-speed riding rice transplanter is not suitable for use in small fields and hilly areas because of its large size. SUMMARY

[0003] In view of the problems of the prior art, the utility model provides the following technical scheme:

[0004] A hand-held step type rice transplanter, comprising a center float, a pair of side float plates arranged on both sides of the rear end of the center float, a frame, an engine, a walking wheel, a seedling box, a rice transplanting mechanism and an operating handle, the center float and the side float plates are fixedly connected to the bottom of the frame, the engine, the rice transplanting mechanism, the seedling box and the operating handle are sequentially installed on the frame, and the operating handle is installed on one side of the frame and can be arranged on the left side or the right side. Since it is a hand-held step type, the rice transplanting row spacing is small, and when a person walks on one side, he or she will not step on the male and female seedlings planted at different periods.

[0005] Preferably, the walking wheel is a two-wheel, which is arranged on both sides of the center float, the power output by the engine is transmitted to the gear box through the belt, and the power is transmitted to the wheel transmission shaft and the wheel shaft through the gear transmission mechanism of the gear box to drive the walking wheel to move forward and backward. The other group of power is transmitted to the planting transmission middle box through the middle support transmission shaft, and the planting transmission middle box drives the side box gear box through the speed change mechanism and the planting transmission shaft to drive the rice transplanting mechanism to complete the rice transplanting operation through the chain transmission inside the side box gear box.

[0006] Preferably, the rice seedling inserting mechanism is provided with multiple groups, which are arranged at both sides of the rear end of the center float, and each group comprises a rice seedling inserting shaft, a transmission arm, a rocker, a inserting arm and a seedling claw.

[0007] Preferably, the inserting arm is of a middle bending structure, and the inserting arms at both sides are bent towards the center.

[0008] Preferably, the distance between the adjacent inserting arms is 20 cm, so as to match the agronomic requirements of some special rice varieties, especially the demand for seed production in the seed production area. The 20 cm row spacing shortens the propagation distance of natural pollination of the male parent and the female parent, improves the fertilization rate of the female parent rice, and finally forms a full endochylema and a rice grain, thereby improving the yield.

[0009] Preferably, the support of the operating handle is further provided with an operating table.

[0010] Preferably, the center float is an axis-symmetrical plastic plate, and the tail width is 10-18 cm.

[0011] Preferably, the side float plate has a width of 10-18 cm.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] 1. In the utility model, the inserting arm is of a middle bending structure, and the inserting arms at both sides are bent towards the center, so that the rice seedling inserting mechanism can complete the work without changing the mechanical structure of the rice seedling inserting machine, the row spacing of the seedlings is reduced to 20 cm, the agronomic requirements of seed production in some areas are met, the demand for manual labor for seed production is greatly reduced, and the operating handle is arranged on one side of the frame, so that the personnel will not step on the male parent seedlings and the female parent seedlings planted at different periods when walking in the field.

[0014] 2. In the utility model, the power of the engine is divided into two groups through the gear box, and the work of the rice seedling inserting mechanism can be realized through the transmission mechanism, so that the structure is simpler and easier to control. BRIEF DESCRIPTION OF DRAWINGS

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. In the embodiments, the description about the position is based on the visual angle of the operator standing at the operating handle position. Based on the embodiments of the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0019] Please refer to Figs. 1-3 A hand-held step-by-step transplanter comprises a center float, a pair of side floats arranged at the two sides of the rear end of the center float, a frame, an engine, a walking wheel, a seedling box, a transplanting mechanism, and an operating handle. The center float and the side floats are fixedly connected to the bottom of the frame. The frame is sequentially provided with the engine, the transplanting mechanism, the seedling box, and the operating handle. The operating handle is arranged on one side of the frame and can be arranged on the left side or the right side. Since it is a hand-held step-by-step transplanter, the spacing between the transplants is small. When a person walks on one side, the male and female parent seedlings transplanted at different times will not be stepped on.

[0020] Specifically, the walking wheel is a two-wheel structure and is arranged at the two sides of the center float. The power output by the engine is transmitted to the gear box through a belt. The power is transmitted to the wheel transmission shaft and the wheel shaft through the gear transmission mechanism of the gear box, so as to drive the walking wheel to move forward and backward. The other power is transmitted to the transplanting transmission middle box through the middle support transmission shaft. The power is transmitted to the side box gear box through the speed change mechanism of the transplanting transmission middle box and the transplanting transmission shaft. The side box gear box is driven to complete the transplanting operation through the chain transmission inside the side box gear box.

[0021] Specifically, the transplanting mechanism comprises a plurality of groups. The machine adopts two groups. Each group comprises two transplanting arms arranged at the two sides of the rear end of the center float. The transplanting shaft, the transmission arm, the rocker, the transplanting arm, and the seedling claw are arranged. The transmission arm is arranged at the two sides of the transplanting shaft. The transplanting arm is movably connected with the transmission arm and the rocker. The seedling claw is arranged at the front end of the transplanting arm. The chain transmission inside the side box gear box drives the rotation of the transplanting shaft, and then drives the transmission arm, the rocker, and the transplanting arm to realize the motion synthesis of the rotary motion and the linear reciprocating motion. The seedling claw completes the actions of taking seedlings, transplanting, and returning.

[0022] Specifically, the transplanting arm is a middle bending structure. The two transplanting arms are bent towards the center. The conventional hand-held step-by-step transplanter adopts a straight transplanting arm. After the transplanting shaft near the center float is connected with the transplanting arm, the seedling claw on the transplanting arm still has a certain spacing from the center float, which leads to a large spacing between the seedlings in the middle. The design of the bending transplanting arm towards the center can reduce the spacing between the seedling claw and the center float, so as to reduce the spacing between the rows.

[0023] Specifically, the spacing between adjacent insertion arms is 20 cm, including the center float and the two adjacent insertion arms on both sides.

[0024] Specifically, the support of the operating handle is also provided with an operating table.

[0025] Specifically, the center float is an axisymmetric plastic plate, and the tail width is 15 cm.

[0026] Specifically, the side float plate is 15 cm wide and just passes between the seedlings when moving.

[0027] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
