Description

TECHNICAL FIELD

[0002] The existing test field is mostly a small area plot, and the planting area of each test variety is only 15 square meters. The size of the plot is mostly 3*5 meters in regular layout. Under this background, the rice transplanting operation is completely completed by manual work, and the single transplanting period lasts for 4-5 days. The operation personnel are difficult to adapt to high-intensity field work. At the same time, manual transplanting adopts the traditional line pulling and dotting method, which not only has complicated operation, but also causes the operation personnel to be ill in high-temperature weather, causing safety risks, and the operation efficiency is extremely low. In addition, manual operation is difficult to ensure the high consistency of the parameters such as the distance between seedlings and the depth, and the transplanting standardization is insufficient, which causes the test data to be discrete, and affects the scientificity and reliability of the scientific research results. With the continuous improvement of the requirements of agricultural scientific research on test accuracy and efficiency, it is urgent to develop an automatic rice transplanting device suitable for test field plots to solve the pain points of the existing operation mode, realize the standardization, precision and high efficiency of the test field transplanting operation, and provide reliable technical support for agricultural scientific research.

[0017] The present application has the following beneficial effects:

[0018] As Figs. 1 to 4 The present application has the following beneficial effects:

[0019] On the ridge of the test field, a plurality of ground rails 1 are arranged in an interval and parallel mode according to the layout of the test field. The ground rail 1 is made of high-strength aluminum alloy material, has the advantages of light weight, corrosion resistance and high strength, can effectively reduce the resistance of the self-propelled frame 2 during walking, and prolong the service life.

[0020] The length of the ground rail 1 is determined according to the width of the test field, which is 15-18 meters, and the span of the row frame type rice transplanter is 15-18 meters. The middle of the test field is divided into two parts, and there is a drainage ditch in the middle. Each variety is 15 square meters, and each variety is inserted into 8 rows. The row frame is equipped with 4 rows of rice transplanter.

[0021] The ground rail 1 is fixed on the ridge by ground screws. This fixing method is firm and can withstand the pressure and friction force when the self-propelled frame 2 is walking. At the same time, it is convenient to disassemble and maintain, and convenient to transfer and re-arrange between different test fields.

[0022] The self-propelled frame 2 is composed of a skeleton 21 and a driving wheel 22. The skeleton 21 is welded by high-strength steel material to form a stable frame structure, which has high carrying capacity and anti-deformation ability, and can ensure the stability of the self-propelled frame 2 during walking.

[0023] Two driving wheels 22 are installed on both sides of the skeleton 21. The driving wheel 22 adopts an electric rudder wheel, and each driving wheel 22 is equipped with a 1-kilowatt motor as a driving source. The motor is powered by a lithium battery. The driving wheel 22 supports independent driving and speed precise control, can realize 180-degree rotation, meets the flexible turning requirement of 90 degrees when turning the field, and ensures the precise control of the walking direction.

[0024] High-precision screw rod transmission structure is adopted in the electric lifting rod 23 installed on both sides of the skeleton 21. The lifting is stable and the positioning is accurate, and the lifting range reaches 50 centimeters. A driving wheel 22 is arranged at the free end of each electric lifting rod 23. By controlling the extension and retraction of the electric lifting rod 23, the height of the row frame 3 can be adjusted.

[0025] The row frame 3 is constructed by high-strength lightweight material, which ensures the structural rigidity while improving the field passability. In order to realize the position adjustment of the self-propelled frame on the row frame (suitable for test fields of different widths), an electric push rod 32 and a sliding rail 31 matched with a pulley are arranged on the row frame 3. The electric push rod 32 is connected with the self-propelled frame 2 and pushes the self-propelled frame to slide on the row frame.

[0026] A rack 33 is installed on the row frame 3. The rack 33 is used to mesh with the gear 40 on the rice transplanter 4. The gear 40 is driven to rotate by the motor, realizing the walking driving of the rice transplanter 4 on the row frame 3. During use, the rice transplanting is carried out along the rail 31. When it is necessary to change the row, the driving wheel 22 works to move two rice planting row distances. The rice transplanter carries out reciprocating rice planting operation. When turning the field, the rice transplanter does not move, and the driving wheel 22 works.

[0027] The gear and rack transmission mode has the advantages of high transmission precision, stable transmission, and strong carrying capacity, which can ensure the speed stability and position accuracy of the rice transplanter 4 when walking on the row frame 3, and provides protection for the standardization and precision of the rice planting operation.

[0028] The holder 41 is installed on the transplanter 4, and the guide pulley 42 is arranged on the holder 41 and in contact with the lower end surface of the frame 3, thereby playing a role in guiding and stabilizing the movement of the transplanter 4. The rolling surface of the guide pulley 42 is provided with a groove matched with the frame 3, which can effectively limit the transverse movement of the transplanter 4 on the frame 3, ensure the stable movement of the transplanter 4 on the frame 3, and avoid unstable movement. The double guiding design (gear and rack transmission and guide pulley matching) not only improves the stability of the transplanter 4, but also effectively reduces the vibration and noise during movement, and improves the quality of the transplanting operation.

[0029] The transplanter 4 is a mature structure, and the structure and principle thereof will not be described in detail.

[0030] The drive wheels 22 of the self-propelled frame 2 are driven by the motor to move along the rails 1. Each drive wheel 22 is equipped with a 1-kilowatt motor, which supports independent driving and precise speed control, can rotate by 180 degrees, and meets the flexible turning requirement of 90 degrees when changing fields. When the self-propelled frame 2 reaches the head of the test field, the drive wheel 22 is turned by 90 degrees, then moves to the next rail 1, is turned by 90 degrees again, symmetrically to the next rail, and then performs the next area of the transplanting operation in the same way.

[0031] In the field changing process: 1. The electric lifting rod 23 adjusts the height of the frame 3, so that the device moves from the ridge to the field passage; 2. The steering motor in the drive wheel 22 rotates the wheel by 90 degrees, and switches to land movement; 3. The land movement drives the whole device to move in the head passage, and turns to the next field; 4. After reaching the new field, the steering motor adjusts the wheel by 90 degrees again, so that the rail moving wheel is clamped into the new ridge rail, and the operation mode is restored.

[0032] When it is necessary to adjust the distance between the two self-propelled frames 2, the distance between the two self-propelled frames is adjusted by the electric push rod, so as to adapt to the test field operation requirement of 15-18 meters wide. This mechatronic adjustment mechanism realizes flexible switching and stable support of the span, and meets the transplanting operation scene of different plots.

[0033] Meanwhile, the electric lifting rod 23 can adjust the height of the drive wheel 22 as needed, so as to ensure the smooth sliding of the self-propelled frame 2 on the frame 3. This double adjustment mechanism (electric push rod and electric lifting rod 23) not only can realize accurate spacing adjustment, but also can maintain the stable movement of the self-propelled frame 2 during the adjustment, so as to avoid the uneven transplanting phenomenon caused by improper distance adjustment.

[0034] The above merely describes the preferred embodiments of the present application, and it should be pointed out that those skilled in the art can make several improvements without departing from the principles of the present application, and these improvements should also be considered as the protection scope of the present application.
