Description

Technical Field

[0001] The utility model belongs to the technical field of seed drills, and in particular relates to a seed drill with adjustable seeding spacing and plant spacing. Background Art

[0002] Traditional seed sowing mostly adopts manual sowing or mechanical sowing. When using manual sowing, problems such as uneven sowing and low sowing efficiency are prone to occur, which cannot meet the requirements of modern society for labor productivity. Although the work efficiency has been significantly improved by using machines instead of manual sowing, the existing sowing machines are complex in structure, large in size, high in cost, and have high requirements for terrain, so they are not suitable for sowing in a small area. At present, hand-held hand-cranked seeders have appeared on the market. The seeder drives the sowing wind wheel to rotate by shaking the handle for sowing. The sowing range is small. When using it, the worker holds the seeder and shakes the handle manually, which increases the labor intensity of the workers and reduces the sowing efficiency. In addition, the shaking frequency is difficult to control, resulting in uneven sowing. Therefore, we designed a seeder with adjustable sowing spacing and plant spacing. Utility Model Content

A conveying groove for conveying seeds is provided on the movable rod 42. A connecting rod 421 is fixedly installed on the upper end of the movable rod 42. A stopper 422 is fixedly installed on the upper end of the connecting rod 421. An inclined surface inclined to the guide groove 412 is provided on the upper end of the stopper 422. A mounting groove 411 and a guide groove 412 connected to the seed feeding hole 41 are provided in the sowing cylinder 4. A fixed rod 423 is fixedly installed on the upper part of the movable rod 42. The fixed rod 423 is movable in the mounting groove 411. A tension spring 424 is fixedly installed between the fixed rod 423 and the groove wall of the mounting groove 411.

[0029] The pushing frame includes a T-bar 5, a fixed sleeve 51, an insert rod 52 and a locking bolt 53. The fixed sleeve 51 is fixedly installed at the lower end of the T-bar 5, and the insert rod 52 is movably inserted at both ends of the fixed sleeve 51. The end of the insert rod 52 is rotatably connected to the seed storage box 1. A threaded hole is opened on the fixed sleeve 51, and the locking bolt 53 is threadedly connected in the threaded hole.

[0030] A rubber gasket is rotatably mounted on the lower end of the locking bolt 53 , and the rubber gasket is in close contact with the portion of the insertion rod 52 extending into the fixed sleeve 51 . The rubber gasket increases the friction force, so that the locking bolt 53 can lock the insertion rod 52 more tightly.

[0031] A conical cover 6 is fixedly installed on the lower end of the movable rod 42, and a limiting cylinder 61 is fixedly installed on the inner wall of the conical cover 6. A movable push rod 62 is movably installed in the limiting cylinder 61, and a compression spring is fixedly installed between the movable push rod 62 and the cylinder wall of the limiting cylinder 61.

An inclined groove is provided on the inner wall of the conical cover 6, and a convex column is provided on the movable push rod 62, which extends into the inclined groove. The conical cover 6 can be used to more conveniently drill holes in the soil. When the movable push rod 62 conflicts with the ground, the rotating baffle 63 will release the obstruction of the lower end opening of the conical cover 6 to facilitate the falling of seeds in the conical cover 6.

[0032] The sowing tube 4 is provided with a mounting hole connected to the mounting groove 411 , and an internal thread is provided in the mounting hole, and a positioning bolt 7 is connected to the internal thread of the mounting hole.

[0033] The method of using the utility model is as follows:

[0034] When in use, open the movable plug 3, send the seeds into the seed storage box 1 through the addition port 2, then reinstall the movable plug 3, and screw the positioning bolt 7 as needed. When the positioning bolt 7 extends into the installation groove 411 and contacts the lower end of the fixing rod 423, it will block the fixing rod 423 to prevent the movable rod 42 from moving. By changing the number of activities of the sowing cylinder 4, the plant spacing during sowing is adjusted;

[0035] The locking bolt 53 is turned to make the insertion rod 52 move at the end of the fixed sleeve 51. After adjusting the spacing between the two sets of sowing mechanisms, the locking bolt 53 is turned again. The rubber gasket at the lower end of the locking bolt 53 will press the insertion rod 52 tightly, and the distance between the two sets of sowing mechanisms is fixed, thereby adjusting the spacing during sowing.

[0036] The seeder is pushed in the field by the T-bar 5, and the seed storage box 1 rotates accordingly. The conical cover 6 on the seeding cylinder 4 is constantly in contact with the soil, pressing a conical groove on the soil. When the seeder is active, multiple seeding cylinders 4 are in contact with the ground one after another, and the entire seeding mechanism is in a state of ups and downs and moving in the thrust direction. When the seeding cylinder 4 is stationary or inverted, the conical cover 6 at the bottom of the seeding cylinder 4 is subjected to the tension of the tension spring 424, and the stopper 422 at the top of the connecting rod 421 is forced to block the seeding hole 41 through the fixed rod 423. When active, the movable rod in the seeding cylinder close to the ground 42. The conical cover 6 as a whole will pull the connecting rod 421 and the block 422 to move under the action of inertia, the tension spring 421 is in an extended state, and the block 422 is separated from the seed inlet hole 41, so that the seeds in the seed storage box 1 enter the conveying groove of the movable rod 42 through the guide groove 412, and finally the seeds are sown into the conical groove through the conical cover 6. When the movable push rod 62 contacts the ground, the rotating baffle 63 rotates to release the obstruction of the lower end opening of the conical cover 6, so that the seeds in the conical cover 6 can fall and complete the sowing. The operation is simple, the sowing spacing and plant spacing can be adjusted, and it is more convenient to use.
