[0002] The existing seeder structure is a hand-pushed rolling seeder as disclosed in the Chinese utility model patent with the publication number CN201467660U. Its main structure includes a seed and fertilizer box and seed nozzles. The structure of the seed and fertilizer box includes a connecting plate body located in the middle and several splicing blocks. The connecting plate body is disc-shaped, and several splicing blocks are distributed around the connecting plate body. Each splicing block is provided with a seed nozzle.

[0003] During the actual installation of the above type of seeder, it is necessary to assemble the splicing blocks one by one around the connecting plate body, and there are at least two or more screw holes on each splicing block. Corresponding screws need to be installed on each screw hole, and the installation is cumbersome; when one of the splicing blocks is damaged and needs to be replaced, it is necessary to remove the corresponding screws, and the disassembly is troublesome. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a clamping mounting structure of a seeder, which has both high installation stability and convenient disassembly and assembly.

[0005] To solve the above technical problems, the technical solution of the utility model is:

[0006] A clamping mounting structure of a seeder includes a drum. The drum includes a connecting plate body located in the middle and several splicing blocks. The several splicing blocks are located around the connecting plate body. Two opposite side walls of the drum are a first side wall and a second side wall. Each splicing block is provided with a splicing groove, and the outer edge of the connecting plate body is inserted into the splicing groove.

[0007] It further includes a clamping part. A flange is provided on the first side wall of each splicing block. The clamping part simultaneously clamps the flanges on all the splicing blocks, so as to stably connect the splicing blocks and the connecting plate body.

[0008] Through the above technical solution, when it is necessary to install the connecting plate body and several splicing blocks together, the splicing grooves on the several splicing blocks can be inserted into the outer edge of the connecting plate body one by one. At this time, a preliminary pre-fixation will be generated between the splicing blocks and the connecting plate body; then, the clamping part is simultaneously clamped on the flanges of all the splicing blocks. All the splicing blocks are simultaneously subjected to a pulling force towards the center side of the connecting plate body, and a stable connection effect can be generated between the splicing blocks and the connecting plate body; on the contrary, after the clamping part is removed from the flange, the splicing blocks can be easily disassembled from the connecting plate body, and the overall disassembly and assembly are more convenient.

[0009] Preferably, the clamping part comprises a clamping steel wire and a clamping member, the clamping steel wire is pulled on the flange, both ends of the clamping steel wire are connecting ends, and the clamping member is used to pull the two connecting ends closer to each other.

[0010] Through the above technical solution, the clamping wire is put on the flange, and then the two connecting ends of the two clamping wires are brought closer together through the clamping piece. The clamping wire can tighten all the flanges, and the locking stability is high.

[0011] Preferably, the connecting end includes a torsion head formed by bending and twisting the end of a clamping wire, and the clamping member includes a clamping bolt and a clamping nut. The clamping bolt passes through the two torsion heads, and the clamping nut is threadedly connected to the clamping bolt.

[0012] Through the above technical solution, the torsion head and the clamping wire are an integrated structure with high structural stability, without the need for other additional accessories, and effectively controlling the overall manufacturing cost.

[0013] Preferably, a positioning rib is provided on the side wall of the connecting plate body close to the clamping member, a connecting wall is connected between the puzzle block and the flange, and a positioning groove which is engaged with the positioning rib is provided on the connecting wall.

[0014] Through the above technical solution, when the puzzle block is installed on the connecting plate body, the positioning ribs and the positioning grooves cooperate with each other, which can further improve the connection stability between the puzzle block and the connecting plate body.

[0015] Preferably, a connecting wall is connected between the puzzle block and the flange, a positioning boss is provided in the puzzle block, the splicing groove is located between the positioning boss and the connecting wall, and a resistance platform is provided on the side wall of the connecting plate body facing away from the clamping piece, and the resistance platform resists against the positioning boss.

[0016] Through the above technical solution, when the puzzle block is installed on the connecting plate body, the connecting plate body is clamped between the positioning boss and the connecting wall. In addition, the abutment table abuts against the side wall of the positioning boss, so the installation accuracy is higher. The abutment table may also enhance the structural strength of the side wall of the connecting plate body, and the connection stability between the puzzle block and the connecting plate body is higher.

[0017] Preferably, the flange is also provided on the second side wall of each of the puzzle blocks, and the clamping portion is also provided on the flange on the second side wall, and the clamping portion is simultaneously buckled and pulled on the flange on the second side wall.

[0018] Through the above technical solution, the first side wall and the second side wall of the entire drum both adopt a structural form in which the flange and the clamping part cooperate with each other, and the structural strength of the drum is higher.

[0019] Preferably, it further includes a metering cavity housing, a support shaft, and a walking bracket. The support shaft is fixedly connected to the walking bracket. The metering cavity housing is located inside the drum. The support shaft passes through and is rotatably connected to the first side wall. The support shaft is fixedly connected to the outer wall of the metering cavity housing close to the first side wall. A first fitting is provided on the second side wall, and a second fitting is provided on the side wall of the metering cavity housing. When the drum and the metering cavity housing rotate relative to each other, the first fitting and the second fitting cooperate with each other to generate a supporting force on the metering cavity housing.

[0020] Through the above technical solution, the metering cavity housing is in a relatively fixed state, and the drum rotates. At this time, there is a first rotation support point between the first side wall of the drum and the support shaft, and a second fitting support point is generated between the second side wall of the drum and the metering cavity housing through the first fitting and the second fitting. The above two support points are respectively located on the left and right sides of the metering cavity housing. The support stability between the drum and the metering cavity housing is extremely high. During use, it is not easy to have extrusion contact between the two, and the probability of jamming is greatly reduced.

[0021] Preferably, the first fitting includes a rolling hole opened on the second side wall;

[0022] The second fitting includes a rolling member installed on the side wall of the metering cavity housing. The rolling member is in rolling contact with the hole wall of the rolling hole.

[0023] Through the above technical solution, when the drum and the metering cavity housing rotate relative to each other, the rolling member contacts the hole wall of the rolling hole, which not only improves the support stability but also makes the rotation of the drum more flexible.

[0024] Preferably, a rolling groove is opened on the hole wall of the rolling hole, and the rolling member is fitted in the rolling groove.

[0025] Through the above technical solution, the rolling member can be restricted to move within the rolling groove, effectively improving the cooperation stability between the rolling member and the rolling hole.

[0026] Preferably, the rolling member includes rolling blocks. The number of rolling blocks is more than two. The rolling hole is a circular hole. The rolling groove is located on the arc-shaped hole wall of the rolling hole. All the rolling blocks are arranged in a circumferential array centered on the rotation axis of the drum.

[0027] Through the above technical solution, more than two rolling blocks can increase the effective support points between the drum and the metering cavity housing, improving the support stability between the drum and the metering cavity housing. BRIEF DESCRIPTION OF THE DRAWINGS
