DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. The embodiments of the present invention and all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-Figure 12 The multi-row planting rice transplanter comprises a rice seedling loading slide 1 and a driving mechanism 3. The rice seedling loading slide 1 is connected to an electric control slide rail platform 2, and a limiting slot plate 11 is equidistantly arranged on the rice seedling loading slide 1, and a driving mechanism 3 is arranged at the bottom end of the rice seedling loading slide 1, and a rice seedling planting gripper 4 is arranged on the driving mechanism 3; the driving mechanism 3 drives the rice seedling planting gripper 4 to rotate, so that the rice seedling planting gripper 4 reaches the seedling outlet position to grab the rice seedlings, wherein a slide base 12 is fixedly arranged at the bottom end of the rice seedling loading slide 1, and a rice seedling loading auxiliary component is arranged on the top of the slide base 12, and a rice seedling planting auxiliary mechanism is connected to the front side of the slide base 12.

[0020] When placing the seedlings, the seedlings are placed in the limiting groove formed by the limiting groove plate 11, and the limiting tube 502 in the seedling loading auxiliary component is used in conjunction with the guiding movable plug rod 601 to limit the position, so that the seedlings can slide smoothly to the seedling outlet position at the bottom of the seedling loading slide 1, and in this scheme, two groups of limiting tubes 502 are arranged in the limiting groove, and the limiting tubes 502 divide the limiting groove into equal parts, that is, the sliding seedlings can be prevented from being offset, so that they can accurately reach the seedling outlet position, so as to avoid pauses or even terminations that affect the seedling planting work.

[0021] In order to further improve the smoothness of the sliding of the seedlings and to facilitate the staff to place the seedlings, the auxiliary baffle body 501 in the seedling loading auxiliary component of this scheme is fixedly set on the slide base 12, the limiting tube 502 is set through the auxiliary baffle body 501, and the outer side wall of one end of the limiting tube 502 is provided with a connecting thread 503, the first fastening screw sleeve 504 is threadedly connected to the limiting tube 502 and is located on one side of the auxiliary baffle body 501, and the second fastening screw sleeve 505 is threadedly connected to the limiting tube 502 and is located on the other side of the auxiliary baffle body 501; a limiting groove is formed between adjacent limiting groove plates 11; the outer side walls of the second fastening screw sleeve 505 and the first fastening screw sleeve 504 are both fixedly provided with a rotating auxiliary protrusion 506; two limiting tubes 502 are provided in one limiting groove, and the two limiting tubes 502 divide the limiting groove into equal parts ; A guide accessory is provided in the limiting tube 502, and the guide movable plug rod 601 in the guide accessory is movably inserted in the limiting tube 502, and an elbow handle 602 is fixedly provided at one end of the guide movable plug rod 601, and an auxiliary spring 605 is fixedly provided at the other end of the guide movable plug rod 601, and a supporting round block 606 is fixedly provided at the other end of the auxiliary spring 605, and the supporting round block 606 is welded and fixed at the tube mouth position of one end of the limiting tube 502, and a guide movable plug rod 601 is movably inserted in a limiting tube 502, and the elbow handle 602 at one end of the guide movable plug rod 601 is bent upward; a through hole body 603 is provided in the elbow handle 602, and the auxiliary pressure rod 604 is adapted to be inserted with the through hole body 603, and the auxiliary pressure rod 604 penetrates the elbow handle 602 at one end of the two guide movable plug rods 601 arranged in the limiting groove.

[0022] When placing the seedlings, the first ones placed are directly loaded at the bottom end of the limiting groove. As the seedlings are added, if the number of seedlings is not large, that is, the seedling loading amount does not exceed the top position of the limiting tube 502, there is no need to use the auxiliary pressure rod 604 to be inserted into the through hole 603 on the elbow handle 602. If the loading amount is large at one time, that is, it exceeds the top position of the limiting tube 502, in order to limit the seedlings at the tail end of the seedling loading slide 1, it is necessary to insert the auxiliary pressure rod 604 into the through hole 603 on the elbow handle 602. At this time, the auxiliary pressure rod 604 is equivalent to a handle, that is, the staff pulls up the auxiliary pressure rod 604 to make the guide movable plug rod 601 extend outward from the limiting tube 502. At this time, the auxiliary spring 605 connected to the guide movable plug rod 601 is in a pulled state, and then the seedlings are loaded layer by layer. When the seedlings are loaded, the stretched guiding movable plug rod 601 limits the seedlings at the tail end of the seedling loading slide 1. After loading, the auxiliary pressure rod 604 is loosened. At this time, the auxiliary pressure rod 604 has a tendency to retract under the rebound action of the auxiliary spring 605, and then the auxiliary pressure rod 604 is pressed on one side of the seedling. At this time, the auxiliary pressure rod 604 is equivalent to a pushing rod, that is, the auxiliary pressure rod 604 has a pushing effect on the downward movement of the seedlings, which has a positive effect on improving the smoothness of seedling planting; when the seedlings are grabbed and planted by the seedling planting gripper 4, the auxiliary baffle body 501 arranged on the slide base 12 has a temporary blocking effect on the upper position of the seedlings, that is, when the seedling planting gripper 4 grabs the roots of the seedlings, it can avoid the seedling planting gripper 4 from causing grabbing damage to the branches and leaves on the upper part of the seedlings, which is beneficial to protecting the seedling body.

[0023] The limiting tube 502 is inserted into the auxiliary baffle body 501 and fixed by the cooperation of the first fastening screw sleeve 504 and the second fastening screw sleeve 505. The first fastening screw sleeve 504 and the second fastening screw sleeve 505 are both provided with a rotation auxiliary protrusion 506 for easy rotation, that is, when the limiting tube 502 is installed or disassembled and replaced, the first fastening screw sleeve 504 and the second fastening screw sleeve 505 can be loosened and rotated without the help of external assistance, and can be operated by the staff manually, thereby facilitating the later maintenance and maintenance of the limiting tube 502. And position adjustment work is convenient; for the installation and use of the guiding movable plug rod 601, the guiding movable plug rod 601 is directly inserted into the limiting tube 502, and the end face of one end of the guiding movable plug rod 601 is welded with an auxiliary spring 605, and the other end of the auxiliary spring 605 is welded with a limiting baffle 704, that is, after the guiding movable plug rod 601 is inserted into the limiting tube 502, when the limiting baffle 704 arranged at one end of the auxiliary spring 605 reaches the tube mouth position of one end of the limiting tube 502, the limiting baffle 704 and the limiting tube 502 are welded and fixed.

[0024] During the seedling planting process, that is, when the seedlings are grabbed by the seedling planting gripper 4, in order to avoid the problem of grabbing too many seedlings at one time, the present invention also provides a transplanting and planting auxiliary mechanism on the front side of the slide base 12 to avoid this problem, that is, the two ends of the support body 701 in the transplanting and planting auxiliary mechanism are symmetrically fixed with mounting side plates 702, the mounting side plates 702 are provided with mounting holes, and the mounting side plates 702 are fixedly connected to the front end of the slide base 12 by screws, and the support body 701 is tightly attached to the front end of the slide base 12; the front end of the support body 701 is equidistantly provided with mounting side plates 702. A placement cavity 703 is provided, and limit baffles 704 are symmetrically fixed on both sides of the top cavity of the placement cavity 703. The support body 701 corresponds to the limit groove setting position on the seedling loading slide 1 and the setting number of groups is the same; when the seedlings reach the position of the limit baffle 704 on the support body 701, the seedling planting gripper 4 grabs the seedlings from the placement cavity 703 position, and a grabbing groove is formed between adjacent limit baffles 704 on the support body 701. When the root of the seedling reaches the grabbing groove position, the upper position of the seedling is temporarily blocked by the auxiliary baffle body 501.

[0025] In the work of grabbing the seedlings by the seedling planting gripper 4, in order to better avoid too many seedlings being grabbed at one time, the present scheme is provided with a material-pickup auxiliary component in the placement cavity 703, and the two ends of the connecting shaft 801 in the material-pickup auxiliary component are symmetrically connected with auxiliary bearings 802, and the auxiliary bearings 802 are welded and fixedly arranged on the inner side wall of the placement cavity 703, and the side of the center position of the connecting shaft 801 is equidistantly fixed with a support strip 803, and the other end of the support strip 803 is fixedly provided with an auxiliary support plate 80 4; the auxiliary support plate 804 and the supporting strip body 803 are arranged in corresponding positions, the number of sets is the same, and the cross-sectional shape of the end of the auxiliary support plate 804 is set to be arc-shaped; a material-shifting piece 805 is fixedly arranged on one side of the auxiliary support plate 804, the length of the material-shifting piece 805 and the auxiliary support plate 804 are set equal, and the number of sets of the two is set the same; a limited accommodating groove 807 is arranged in the middle position of the front side of the material-shifting piece 805, and guide inclined surfaces 806 are symmetrically arranged on both sides of the limited accommodating groove 807, and the groove of the limited accommodating groove 807 The opening shape is set to be V-shaped, and the inner side of the limit accommodating groove 807 is provided with an auxiliary soft hair body 808, that is, the seedling planting gripper 4 grabs the seedlings stuck in the upper limit accommodating groove 807 of the material-shifting piece 805 for planting. In the process of grabbing the seedlings from the material-shifting piece 805, the seedling planting gripper 4 grabs the seedlings on the material-shifting piece 805, and after grabbing the seedlings, it has a downward squeezing effect on the material-shifting piece 805 and the auxiliary support plate 804, wherein the material-shifting piece 805 is arranged on one side of the auxiliary support plate 804, and the auxiliary support plate 804 is provided with a plurality of auxiliary hair bodies 808. The plate 804 is arranged at one end of the supporting strip 803, and the supporting strip 803 is arranged on the connecting shaft 801. The two ends of the connecting shaft 801 are sleeved with auxiliary bearings 802, that is, the auxiliary bearings 802 are arranged so that the connecting shaft 801 can rotate. When the auxiliary support plate 804 or the material-shifting piece 805 is squeezed, the squeezed auxiliary support plate 804 and the material-shifting piece 805 can be moved, and then the auxiliary support plate 804 and the material-shifting piece 805 at their positions can be driven to move. After the seedlings on the previous material-shifting piece 805 are grabbed, the subsequent auxiliary support plate 804 and the material-shifting piece 805 will be driven to rotate. During the rotation process, the material-shifting piece 805 arranged on the front side of the auxiliary support plate 804 will drive the roots of the seedlings at the grabbing groove position, and clamp the roots of the seedlings in the limiting accommodating groove 807. During this process, when the material-shifting piece 805 is driving the seedlings to shift materials, when the roots of the seedlings are just in the position corresponding to the limiting accommodating groove 807, the roots of the seedlings can be directly clamped in the limiting accommodating groove 807, and then the next seedling planting gripper 4 will grab the seedlings. If there is a deviation between the roots of the seedlings and the limiting accommodating groove 807 when the material-shifting piece 805 is shifting materials to the seedlings, the guide The inclined surface 806 causes the roots of the seedlings to slide into the limiting accommodating groove 807. During the seedling separation work, the upper position of the seedlings is temporarily blocked by the auxiliary baffle body 501, and the roots of the seedlings slide toward the limiting accommodating groove 807 in the middle position of the material-discharging piece 805 under the action of the guiding inclined surface 806. That is, the purpose of symmetrically arranging the guiding inclined surfaces 806 on both sides of the limiting accommodating groove 807 on the front side of the material-discharging piece 805 in this process is to drive the roots of the seedlings in the grasping groove while keeping the roots of the seedlings in the limiting accommodating groove 807 as much as possible, and the side walls of the limiting accommodating groove 807 are provided with auxiliary soft hair bodies 808, so that when the limiting accommodating groove 807 drives the roots of the seedlings to move, the seedlings are prevented from falling before being grasped and planted.

[0026] The support body 701 is installed and fixed on the front side of the slide base 12 by installing the side plate 702 and screws for easy disassembly and assembly. During long-term work, if the material-pickup piece 805 and the limiting accommodating groove 807 on the material-pickup piece 805 are covered with mud and dirt and need to be cleaned or replaced, the support body 701 can be directly disassembled, and the material-pickup piece 805 placed in the cavity 703 can be cleaned, and then the support body 701 can be installed and fixed. Here, one support body 701 is provided at the bottom of each limiting groove, that is, partial disassembly and replacement can be carried out during maintenance and replacement in the later stage, and the working flexibility is higher.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
