Description
Technical Field
[0001] The utility model relates to the technical field of seeders, in particular to a mechanical seeder for Hedysarum scoparium seeds. Background Art
[0002] A seeder is a planting machine that takes crop seeds as the sowing object. By replacing manual sowing with a seeder, the labor intensity during sowing can be reduced and the sowing accuracy can be improved. The seeder realizes the sowing work through a sowing mechanism.
[0003] Currently, the sowing of Hedysarum scoparium is all carried out manually, without a corresponding mechanical seeder. By modifying a wheat seeder, the existing Hedysarum scoparium seeder is formed. When sowing, first, the seeds are introduced into the interior of the sowing box, and then the motor is started. The motor drives the anti-caking cylinder to stir and disperse the seeds inside the sowing box, thereby preventing the caked seeds from blocking the telescopic sowing tube. Then, the push rod is started to adjust the length of the telescopic sowing tube, thereby controlling the sowing depth. However, achieving the above two effects through the motor and the push rod respectively will result in too many electronic control devices on the sowing mechanism, and the maintenance of the electronic control devices is too complicated. Because the faults of the electronic system are not intuitive enough, it is not easy to detect and repair. The electronic system involves complex circuits and programming, and the maintenance difficulty is relatively large. Too many electronic control devices will increase the difficulty and complexity of maintenance. Content of the Utility Model
[0004] The utility model aims at the deficiencies of the existing technology and provides the following technical solution: A mechanical seeder for Hedysarum scoparium seeds, including a frame body. Wheels are arranged at the bottom of the frame body. A sowing mechanism is arranged on the frame body. The sowing mechanism includes a sowing box. The sowing box is arranged on the frame body. A motor is installed on the frame body. The output end of the motor is connected with a rotating rod. The rotating rod penetrates through the inner wall of the sowing box and is rotatably connected with the sowing box. An anti-caking cylinder is arranged inside the sowing box. The anti-caking cylinder is connected to the surface of the rotating rod. A second meshing wheel is connected to the rotating rod. A telescopic sowing tube is arranged at the lower end of the sowing box. The telescopic sowing tube communicates with the sowing box. The fixed part of the telescopic sowing tube is connected with a fixed plate. The moving part of the telescopic sowing tube is connected with a moving plate. The fixed plate is rotatably connected with a first rotating shaft passing through it. The upper end of the first rotating shaft is connected with a second rotating shaft through an elastic component. The upper end of the second rotating shaft is connected with a first meshing wheel. The second meshing wheel meshes with the first meshing wheel. The lower end of the first rotating shaft is connected with a lead screw. The lead screw is threadedly connected with the moving plate. A furrow opener is arranged at the lower end of the telescopic sowing tube. A soil covering device is connected to the furrow opener.
[0005] As an improvement of the above technical solution, the elastic component includes a rotating disk. The lower end of the second rotating shaft is connected to the rotating disk. The surface of the rotating disk is slidably connected with a plurality of sliding rods penetrating through it. The lower end of the sliding rod is connected to a connecting block, and the connecting block is connected to the first rotating shaft. A spring is wound around the surface of the sliding rod. One end of the spring is connected to the rotating disk, and the other end of the spring is connected to the connecting block.
[0006] As an improvement of the above technical solution, the seeding mechanism further includes an adjusting component. The seeding box is rotatably connected with an adjusting component. The adjusting component includes a driving rod. The seeding box is rotatably connected with a driving rod. One end of the driving rod is connected to a crank, and the other end of the driving rod is connected to a cam. The cam is arranged corresponding to the rotating disk.
[0007] As an improvement of the above technical solution, a return torsion spring is wound around the surface of the driving rod. One end of the return torsion spring is connected to the seeding box, and the other end of the return torsion spring is connected to the driving rod.
[0008] As an improvement of the above technical solution, a plurality of ball bearings are arranged on the surface of the cam.
[0009] The beneficial effects of the present utility model:
[0010] When only stirring and dispersing without adjusting the seeding depth is required, the user presses down the elastic component. Since the elastic component has elasticity, the first meshing wheel can be separated from the second meshing wheel, thereby realizing the single control of the stirring and dispersing effect. Therefore, by setting the seeding mechanism, the number of electronic control devices on this mechanism can be reduced. In the function of controlling the seeding depth, a mechanical structure can be used to replace the electronic control device. The maintenance of the mechanical system is simpler than that of the electronic system because the faults of mechanical components are more intuitive, easy to detect and repair, thus reducing the difficulty and complexity of repairing this mechanism.

Detailed implementation manners
[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0018] Please refer to Figures 1-5 , the present utility model provides a technical solution: a Hedysarum scoparium seed seeding machine, including a frame 1, wheels 2 are arranged at the bottom of the frame 1, a seeding mechanism 3 is arranged on the frame 1, the seeding mechanism 3 includes a seeding box 31, the seeding box 31 is arranged on the frame 1, a motor 32 is installed on the frame 1, the output end of the motor 32 is connected to a rotating rod 33, the rotating rod 33 penetrates through the inner wall of the seeding box 31 and is rotatably connected to the seeding box 31, an anti-caking cylinder 34 is arranged inside the seeding box 31, the anti-caking cylinder 34 is connected to the surface of the rotating rod 33, a second meshing wheel 395 is connected to the rotating rod 33, a telescopic seeding pipe 394 is arranged at the lower end of the seeding box 31, the telescopic seeding pipe 394 communicates with the seeding box 31, the fixed part of the telescopic seeding pipe 394 is connected to a fixing plate 35, the moving part of the telescopic seeding pipe 394 is connected to a moving plate 36, the fixing plate 35 is rotatably connected to a first rotating shaft 37 passing through it, the upper end of the first rotating shaft 37 is connected to a second rotating shaft 391 through an elastic component 39, the upper end of the second rotating shaft 391 is connected to a first meshing wheel 392, the second meshing wheel 395 meshes with the first meshing wheel 392, the lower end of the first rotating shaft 37 is connected to a lead screw 38, the lead screw 38 is threadedly connected to the moving plate 36, a furrow opener 396 is arranged at the lower end of the telescopic seeding pipe 394, and a soil covering device 397 is connected to the furrow opener 396.
[0019] In this embodiment, the motor 32 is first started, and the output end of the motor 32 rotates at a low speed, thereby driving the rotating rod 33 to rotate, and then driving the anti-caking cylinder 34 to rotate. Since the anti-caking cylinder 34 rotates, the caked seeds inside the sowing box 31 can be stirred and dispersed. At the same time, since the rotating rod 33 rotates, the second meshing wheel 395 is driven to rotate, and then the second rotating shaft 391 is driven to rotate through the first meshing wheel 392. Furthermore, the first rotating shaft 37 rotates on the fixed plate 35 through the elastic component 39. Since the first rotating shaft 37 rotates, the lead screw 38 is driven to rotate, and then the telescopic sowing pipe 394 is driven to expand and contract through the moving plate 36. Thus, by the mutual cooperation of the furrow opener 396 and the soil covering device 397, the sowing depth can be adjusted. When only stirring and dispersing are required without adjusting the sowing depth, the user presses down the elastic component 39. Since the elastic component 39 has elasticity, the first meshing wheel 392 can be separated from the second meshing wheel 395, thereby realizing the single control of the stirring and dispersing effect. Therefore, by setting the sowing mechanism 3, the number of electric control devices on this mechanism can be reduced. In the function of controlling the sowing depth, a mechanical structure can be used to replace the electric control device. The maintenance of the mechanical system is simpler than that of the electronic system because the faults of mechanical components are more intuitive and easy to detect and repair, thereby reducing the difficulty and complexity of repairing this mechanism.
[0020] Specifically, the elastic component 39 includes a rotating disk 3901. The lower end of the second rotating shaft 391 is connected to the rotating disk 3901. The surface of the rotating disk 3901 is slidably connected with a plurality of sliding rods 3902 penetrating through it. The lower end of the sliding rod 3902 is connected to a connecting block 3903. The connecting block 3903 is connected to the first rotating shaft 37. A spring 3904 is wound around the surface of the sliding rod 3902. One end of the spring 3904 is connected to the rotating disk 3901, and the other end of the spring 3904 is connected to the connecting block 3903.
[0021] In this embodiment, when the user presses down the rotating disk 3901, the spring 3904 is compressed, so that the rotating disk 3901 slides downward on the surface of the sliding rod 3902, and then drives the first meshing wheel 392 to move downward through the second rotating shaft 391, thereby separating from the second meshing wheel 395.
[0022] Specifically, the sowing mechanism 3 further includes an adjusting component 393. An adjusting component 393 is rotatably connected to the sowing box 31. The adjusting component 393 includes a driving rod 3931. The driving rod 3931 is rotatably connected to the sowing box 31. One end of the driving rod 3931 is connected to a crank 3932, and the other end of the driving rod 3931 is connected to a cam 3933. The cam 3933 is correspondingly arranged with the rotating disk 3901.
[0023] In this embodiment, the user first rotates the crank 3932, thereby driving the drive rod 3931 to rotate on the seeding box 31, and then driving the cam 3933 to rotate. By using the cam 3933 to squeeze the rotating disk 3901, the first engaging wheel 392 can be moved downward, so as to disengage from the second engaging wheel 395, making it more convenient for the user to operate.
[0024] Specifically, a return torsion spring 3934 is wound around the surface of the drive rod 3931. One end of the return torsion spring 3934 is connected to the seeding box 31, and the other end of the return torsion spring 3934 is connected to the drive rod 3931.
[0025] In this embodiment, since the return torsion spring 3934 has a certain return torque, the return torsion spring 3934 can reset the cam 3933.
[0026] Specifically, a number of balls are provided on the surface of the cam 3933.
[0027] In this embodiment, by providing the balls, the friction between the cam 3933 and the rotating disk 3901 can be reduced, making it more convenient for the user to use the cam 3933 to squeeze the rotating disk 3901.
[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
