Description

Technical Field

[0001] The utility model relates to the technical field of farmland sowing equipment, in particular to a drop material blocking prevention seeder for a farmland sowing machine. Background Art

[0002] A seeder is a planting machine that sows crop seeds. It is a seeder used for a certain type of crop and is often named after the crop type, such as grain drill, corn hole seeder, cotton seeder, forage spreader, etc.

[0003] When mechanized sowing is used in farmland, a seeder is generally used for sowing. The grain seeds enter the seeder from the hopper and are rotated by the scoop wheel to bring the grain seeds to the outlet of the seeder.

[0004] However, when there are too many grain seeds stored in the hopper of some existing seeders, blockage may occur, resulting in the grain seeds being unable to fall smoothly into the seed meter, affecting the normal sowing process. Workers are often required to stir the grain seeds in the hopper trough with a stick or knock on the outside of the hopper to clear it, which is time-consuming and labor-intensive, inconvenient for workers to use, and has low work efficiency. Utility Model Content

[0010] The utility model is further configured that the transmission shaft is connected to the pulley via a belt, and a material inlet is provided at one end of the material trough.

[0011] By adopting the above technical solution, the transmission power is transmitted by connecting the transmission shaft and the pulley with a belt, so as to provide power for each structure of the device, thereby making the device structure more perfect.

[0012] The utility model is further configured as follows: a seeding device is fixedly installed on one side of the material trough, and a discharge port is fixedly installed on one end of the seeding device, the fan and the seeding device are connected by a ventilation pipe, a turntable is movably installed on the inside of the seeding device, and a placement port is opened on the side of the turntable, and the number of the placement ports is set in multiple groups.

By installing a turntable, the turntable and the drive shaft rotate, so that the grain seeds can be evenly distributed into the discharge port according to the spacing between the placement ports and implanted into the soil at certain intervals.

[0014] The utility model is further configured that a convex shaft is sleeved on the inner side of the fixing block, and the convex shaft is arranged in two groups, and the fixing block is arranged in four groups.

[0015] By adopting the above technical solution and installing four sets of fixing blocks, the connection between the fixing blocks and the vibration grooves is made more stable, better supporting force is obtained, and the device is more stable when in operation.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] The utility model is provided with a cam shaft, a pulley, a spring, a vibration groove, etc., and a motor drives the transmission shaft to rotate, so that the transmission shaft rotates through the belt drive pulley, thereby rotating the cam shaft, and at the same time the fixed block is limited by the cam shaft and begins to move up and down along the inner side of the material groove.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A material-dropping and anti-blocking seeder for a farmland seeder, such as Figure 1-5 As shown, it includes a mounting plate 1 and a motor 2. A material trough 4 is fixedly mounted on one end of the mounting plate 1, and a vibration trough 7 is movably mounted on the inner side of the material trough 4. A spring 8 is installed between the material trough 4 and the vibration trough 7. Cam shafts 10 are fixedly mounted on both ends of the material trough 4, and fixed blocks 9 are fixedly mounted on both ends of the vibration trough 7. A pulley 11 is fixedly mounted on one end of the cam shaft 10. A transmission shaft 12 is movably mounted on the output end of the motor 2. The transmission shaft 12 is driven to rotate by the motor 2, so that the transmission shaft 12 rotates through the belt drive pulley 11, thereby rotating the cam shaft 10. At the same time, the fixed block 9 is limited by the cam shaft 10 and begins to move up and down along the inner side of the material trough 4. Under the action of the spring 8, the vibration trough 7 generates high-frequency vibrations, so that the activity of the grain seeds in the vibration trough 7 is enhanced under the action of vibration, so that they fall smoothly into the seed metering device.

[0027] See also Figure 4 A fan 3 is fixedly installed at one end of the mounting plate 1, a fan blade 13 is fixedly installed at one end of the transmission shaft 12, and a spiral plate 15 is fixedly installed at the other end of the transmission shaft 12. By installing the spiral plate 15, it is convenient to quickly transfer the grain seeds in the material trough 4 to the seed meter 5 for sowing operations, thereby improving work efficiency.

[0028] See also Figure 1 The transmission shaft 12 is connected to the pulley 11 by a belt, and a feeding port 6 is provided at one end of the material trough 4. The transmission shaft 12 and the pulley 11 are connected by a belt to transmit power, thereby providing power for each structure of the device, making the device structure more perfect.

[0029] See also Figure 4 A turntable 14 is movably installed inside the seed meter 5, and a placement opening 16 is opened on the side of the turntable 14. The number of the placement openings 16 is set in multiple groups. By installing the turntable 14, the turntable 14 and the transmission shaft 12 rotate, so that the grain seeds can be evenly distributed into the discharge opening 17 according to the spacing of the placement openings 16 and implanted into the soil at a certain interval.

[0030] See also Figure 5 A seed meter 5 is fixedly installed on one side of the material trough 4, and a discharge port 17 is fixedly installed on one end of the seed meter 5. The fan 3 and the seed meter 5 are connected by a ventilation pipe 18. By installing the ventilation pipe 18, the adsorption pressure generated by the fan 3 is evenly distributed to the seed meter 5, making the device structure more perfect and the operation more stable.

[0031] See also Figure 2 A convex shaft 10 is mounted on the inner side of the fixed block 9, and the convex shaft 10 is arranged in two groups, and the fixed block 9 is arranged in four groups. By installing four groups of fixed blocks 9, the connection between the fixed block 9 and the vibration groove 7 is more firmly established, and better supporting force is obtained, which makes the device more stable when in operation.

[0032] The working principle of the utility model is as follows: when in use, the grain seeds are put into the material trough 4 from the feeding port 6, and the motor 2 is started. At this time, the motor 2 will drive the transmission shaft 12 to rotate, so that the transmission shaft 12 rotates through the belt drive pulley 11, thereby rotating the cam 10, and at the same time, the fixed block 9 is limited by the cam 10 and begins to move up and down along the inner side of the material trough 4. Under the action of the spring 8, the vibration trough 7 generates high-frequency vibration, so that the grain seeds in the vibration trough 7 are more active under the action of vibration, so that they fall into the seed metering device smoothly. At the same time, the spiral plate 15 will limit the grain seeds in the material trough 4 and transport the grain seeds to one side of the turntable 14 inside the seed metering device 5. At this time, the adsorption pressure generated by the rotation of the fan blades 13 inside the fan 3 will be given to the inside of the seed metering device 5 through the ventilation pipe 18, so that the grain seeds inside the seed metering device 5 will fit on the placement port 16 under the action of the adsorption pressure, and be transferred to the discharge port 17 through the rotation of the turntable 14, and then be put into the soil for sowing through the discharge port 17.
