A material discharge trough is provided at a position of the connection frame 3 corresponding to the sealing plate 61 .

[0024] Specifically, the weeding work of the existing rice transplanter is carried out by combining mechanization and chemical methods. First, during the rice transplanting operation, the spray device equipped with the rice transplanter will simultaneously spray soil sealing herbicides, which can quickly cover the soil surface to form a protective film to prevent weed seeds from germinating. At the same time, according to the type and distribution of weeds in the field, appropriate stem and leaf treatment agents can also be selected and sprayed by a rice transplanter or a mist machine to directly act on the grown weeds to further control the growth of weeds. This working method is not only efficient, but also ensures that the herbicide can be evenly distributed in the field, providing a good environment for rice growth. The above scheme still has some problems in practical application, because the use of herbicides may cause phytotoxicity to the seedlings, especially in the weaning period when the resistance of the seedlings is weak, which may cause the seedlings to be damaged, thereby causing the seedlings to have weak resistance and fail to survive in subsequent growth; Therefore, the present invention solves this problem by setting a certain structure. First, the rice transplanter is moved into the rice field. Because there are a lot of weeds floating in the water in the rice field, the rice transplanter 26 may insert the weeds into the soil in the process of transplanting, which will cause the subsequent growth of the seedlings to be compressed by the weeds. The living space, therefore, needs to be cleaned up in the rice field. When transplanting, the rice seedlings to be transplanted are first placed in the fixed groove 14, and the position is limited by the limit assembly, and then the rice transplanter is pulled to move along the rice field where the rice seedlings need to be transplanted. When the movement starts, the first motor 2 is started, and the first motor 2 drives the first gear 23 to rotate. The rotation of the first gear 23 drives the fixed shaft 22 in the middle to rotate. The two sides of the fixed shaft 22 are connected to the drive shaft 24 by the gear and rack method respectively. The rotation of the drive shaft 24 can rotate the rice transplanter 26 of the entire rice transplanter, thereby controlling the rice transplanter 26 to continuously reciprocate for transplanting, thereby achieving the effect of high-efficiency rice transplanting. In addition, before starting the first motor 2, the second motor 4 is started, and the second motor 4 will drive the first rotating wheel 41 fixed to its output end to rotate, and the rotation of the first rotating wheel 41 can drive the second rack 42 to transmit, and the transmission of the second rack 42 will drive the second rotating wheel 46 to rotate, and the rotation of the second rotating wheel 46 can drive the connecting shaft 47 in the middle to rotate, and the rotation of the connecting shaft 47 can drive a plurality of cleaning rods 48 fixed to its circumferential surface to rotate, and the cleaning rods 48 pick up the weeds in the rice field through a plurality of fixed columns 49 on both sides thereof, and then achieve the effect of clearing the weeds in the rice field, thereby removing the weeds in the rice field, and the weeds picked up on the fixed columns 49 will It is placed in the first cavity 31 of the connecting frame 3. When the first motor 2 drives the connecting shaft 47, it will also drive the reciprocating screw 43 at its output end to rotate. The rotation of the reciprocating screw 43 can drive the scraper 44 slidably connected to its circumferential surface to slide. The sliding of the scraper 44 can squeeze the picked up weeds into a certain block. When the weeds accumulate to a certain extent, the two first hydraulic cylinders 6 on the lower surface of the connecting frame 3 are started, so that the first hydraulic cylinders 6 drive the sealing plates 61 at their output ends to open the discharge chute on the lower surface of the connecting frame 3. At this time, the weeds squeezed into blocks will fall into the rice field and return to the field, thereby achieving the effect of automatically cleaning and packing the weeds and improving the efficiency of removing weeds in the rice field.

[0025] Embodiment 2:

[0026] like Figures 2 to 9 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a plurality of rotating blades 12 are fixedly connected to the circumferential surface of each rotating wheel 11, and the rotating blades 12 are used to assist the movement of the rotating wheel 11, and a control handle 13 is fixedly connected to one side of the fixed platform 1; A limiting assembly is arranged inside each fixed groove 14, and the limiting assembly includes a fixed guide rail 5 fixedly connected in the fixed groove 14, and a limiting groove 51 is provided in each fixed guide rail 5, and a guide block 52 is slidably connected in the limiting groove 51, and a fixing plate 53 is fixedly connected to the upper surface of the guide block 52, and the fixing plate 53 is used to limit the position of the seedlings; A scraper 54 is fixedly connected to one side of each fixed plate 53, and the scraper 54 is used to clean the residual sludge in the fixed tank 14; An arc-shaped plate 16 is fixedly connected to one side of each connecting plate 15 . Two positioning plates 17 are fixedly connected to the lower surface of each connecting plate 15 . A positioning groove 18 is defined between the two positioning plates 17 .

[0027] Specifically, after starting the rice transplanter, the two rotating wheels 11 are driven to rotate by the built-in motor, thereby driving the entire rice transplanter to move. A plurality of rotating blades 12 are fixedly connected to the circumferential surface of the rotating wheel 11 to prevent the rice transplanter from sinking into the mud. In addition, after the rice seedlings are placed in the fixed groove 14, the guide rails in the fixed guide rails 5 are started to drive the fixed plate 53 to limit the rice seedlings, thereby preventing the roots of the rice seedlings from becoming soft during the rice seedling reduction process, and preventing the rice seedlings from being clamped by the rice transplanting piece 26, resulting in poor rice transplanting quality. Therefore, the roots of the rice seedlings are continuously squeezed by the limiting of the fixed plate 53 so that they can abut against the rice transplanting piece 26, thereby achieving the effect of improving the rice transplanting quality. At the same time, a scraper block 54 is fixedly connected to one side of the fixed plate 53, and the scraper block 54 can clean the residual sludge in the fixed groove 14, and then the soil on both sides of the rice seedlings is gathered back through the two arc-shaped plates 16 on the lower surface of the connecting plate 15, so that the planting effect of the rice seedlings is better and the survival rate of the rice seedlings is improved.

[0028] Working principle: first start the rice transplanter, and use the built-in motor to drive the two rotating wheels 11 to rotate, thereby driving the entire rice transplanter to move, and a number of rotating blades 12 are fixed on the circumferential surface of the rotating wheel 11 to prevent the rice transplanter from sinking into the mud; Because there are a lot of weeds floating in the water in the rice field, the transplanting piece 26 may insert the weeds into the soil during the transplanting process, which will cause the growth of the subsequent seedlings to be compressed by the weeds. Living space, therefore, it is necessary to clean the weeds in the rice field. When transplanting, the seedlings to be transplanted are first placed in the fixed groove 14. After the seedlings are placed in the fixed groove 14, the guide rails in the fixed guide rails 5 are started to drive the fixed plate 53 to limit the position of the seedlings, thereby preventing the roots of the seedlings from becoming soft during the seedling reduction process. The transplanting piece 26 cannot clamp the seedlings, resulting in poor transplanting quality. Therefore, the roots of the seedlings are continuously squeezed by the limiting position of the fixed plate 53 so that they can abut against the transplanting piece 26, thereby achieving the effect of improving the transplanting quality. At the same time, a scraper block 54 is fixed to one side of the fixed plate 53, and the scraper block 54 can The residual sludge in the fixed groove 14 is cleaned, and then the soil on both sides of the seedlings is gathered through the two arc-shaped plates 16 on the lower surface of the connecting plate 15, so that the planting effect of the seedlings is better and the survival rate of the seedlings is improved. Then the rice transplanter is pulled to move along the rice field where rice transplanting is required. When the movement starts, the first motor 2 is started, and the first motor 2 drives the first gear 23 to rotate. The rotation of the first gear 23 drives the fixed shaft 22 in the middle to rotate. The two sides of the fixed shaft 22 are respectively connected with the driving shaft 24 by the way of gears and racks. The rotation of the driving shaft 24 can rotate the transplanting part 26 of the entire rice transplanter, so as to control the transplanting part 26 to continuously reciprocate for transplanting, thereby achieving the effect of high-efficiency transplanting; the transplanting part 26 adopts the traditional four-link transmission structure and the structural design of the top rod, which are not within the protection scope of the present invention.

[0029] In addition, before starting the first motor 2, the second motor 4 is started, and the second motor 4 will drive the first rotating wheel 41 fixed to its output end to rotate, and the rotation of the first rotating wheel 41 can drive the second rack 42 to transmit, and the transmission of the second rack 42 will drive the second rotating wheel 46 to rotate, and the rotation of the second rotating wheel 46 can drive the connecting shaft 47 in the middle to rotate, and the rotation of the connecting shaft 47 can drive a plurality of cleaning rods 48 fixed to its circumferential surface to rotate, and the cleaning rods 48 pick up the weeds in the rice field through a plurality of fixed columns 49 on both sides thereof, and then achieve the effect of clearing the weeds in the rice field, thereby removing the weeds in the rice field, and the weeds picked up on the fixed columns 49 will It is placed in the first cavity 31 of the connecting frame 3. When the first motor 2 drives the connecting shaft 47, it will also drive the reciprocating screw 43 at its output end to rotate. The rotation of the reciprocating screw 43 can drive the scraper 44 slidably connected to its circumferential surface to slide. The sliding of the scraper 44 can squeeze the picked up weeds into a certain block. When the weeds accumulate to a certain extent, the two first hydraulic cylinders 6 on the lower surface of the connecting frame 3 are started, so that the first hydraulic cylinders 6 drive the sealing plates 61 at their output ends to open the discharge chute on the lower surface of the connecting frame 3. At this time, the weeds squeezed into blocks will fall into the rice field and return to the field, thereby achieving the effect of automatically cleaning and packing the weeds and improving the efficiency of removing weeds in the rice field.
