A grain planting device

Abstract

This invention provides a grain planting device, including a hopper for storing grain seeds, a rotating disk disposed within the hopper, a seed-collecting device mounted on the rotating disk for collecting grain seeds, and a guide pipe disposed within the hopper for guiding the grain seeds collected by the seed-collecting device out of the hopper. The rotating disk can rotate at high speed or uniform speed relative to the hopper, allowing the seed-collecting device to collect at least one grain seed, and the guide pipe to scrape the collected grain seeds from the seed-collecting device and guide them out of the hopper. Seeds are collected from the hopper through several continuously rotating vacuum nozzles, and then the guide pipe scrapes off each grain seed adsorbed on the vacuum nozzle and guides it out of the hopper. This vacuum suction method ensures that the seeds are not damaged while maintaining consistency in the number of grain seeds collected each time, achieving precise control of the number of seeds collected.

Description

Technical Field

[0001] This invention relates to a grain growing device. Background Technology

[0002] A grain sowing device is used to sow grains in soil, that is, to carry out planting operations in suitable locations. For most grain seeds, planting involves first digging a hole, then placing the seed in the hole, followed by covering with soil, compacting, and watering. While some electrically operated hole-digging and sowing devices exist, the lack of a device to control the number of seeds during actual sowing results in uneven sowing, with some holes containing more seeds than others.

[0003] Chinese patent discloses a grain sowing device (201611270602.4). Driven by a power device, a baffle can rotate a shovel around a pivot, causing the shovel to swing and rest against a stop block. The shovel inserts into the soil, digging a hole as the baffle rotates. As the baffle rotates, when the notch on the baffle aligns with the discharge port at the lower end of the inclined tube, the seeds inside the inclined tube can pass through the baffle and fall into the hole, thus completing the digging and sowing process. During each sowing process, the cylinder contracts once, causing the seeds in the storage bin to flow through the inclined tube and fall into the hole. This avoids seed accumulation on the concave surface of the baffle, preventing waste. Each time the plate moves, the seeds discharged from the storage bin fall into the hole, and the number of seeds discharged from the storage bin is consistent each time. Furthermore, the support device ensures that the plate remains horizontal during each translation. In practical use, the actual size of the seeds varies, and consistency cannot be guaranteed. Therefore, this technical solution cannot ensure that the number of seeds released each time is consistent. In other words, it cannot precisely control the number of seeds released, and thus needs to be improved. Summary of the Invention

[0004] The main objective of this invention is to solve the above-mentioned problems and provide a grain planting device that can accurately control the number of grain seeds below.

[0005] The technical solution adopted in this invention is as follows: a grain planting device, comprising a silo for storing grain seeds, a rotating disk disposed in the silo, a suction device for suctioning grain seeds mounted on the rotating disk, and a guide pipe disposed in the silo for guiding the grain seeds suctioned by the suction device out of the silo, so that the rotating disk can rotate at high speed or at a constant speed relative to the silo, so that the suction device can suction at least one grain seed, and the guide pipe can scrape the suctioned grain seed from the suction device and guide it out of the silo.

[0006] The suction device includes several vacuum nozzles equidistantly arranged around the rotating disk and at least one vacuum pump that provides vacuum suction to each vacuum nozzle, so that the vacuum nozzle can suck up at least one grain seed in the hopper, and then scrape the grain seed off the vacuum nozzle one by one through the guide tube and guide it out of the hopper.

[0007] The hopper has an inlet and an outlet, and the rotary disk is rotatably mounted in the outlet via a ring-shaped rotating assembly.

[0008] The annular rotating assembly includes an annular guide rail and an annular slider rotatably mounted on the annular guide rail, with the rotating disk fixed on the annular slider.

[0009] The grain planting device includes a drive motor for driving the rotating disk to rotate. The drive motor is fixed to the outside of the hopper via a motor frame, and the motor shaft of the drive motor is fixed to the rotating disk.

[0010] The motor shaft of the drive motor is fixed to the rotating disk via a connecting pipe. Each vacuum nozzle is connected to the connecting pipe via an air pipe. The vacuum pump is connected to the connecting pipe. One end of the connecting pipe is provided with a connecting plate that is fixed to the rotating disk. The other end of the connecting pipe is fixed to the motor shaft of the drive motor. The connecting plate is provided with several air holes for connecting to the air pipes to facilitate the connection of the air pipes.

[0011] The rotating disc ring is provided with several mounting holes for connecting the vacuum nozzle. A suction kit is provided in the mounting holes. The suction kit includes a cylinder connected to the vacuum nozzle and a soft body provided at the end of the cylinder for suctioning grain seeds. The top surface of the soft body is set as a conical surface. The soft body is provided with several through holes that penetrate the cylinder so that the vacuum nozzle can suction the grain seeds onto the soft body when vacuuming.

[0012] The guide tube is fixed inside the hopper, with one end extending to the position of the rotating disk and the other end extending outside the hopper. The end of the guide tube near the rotating disk has a notch for grain seeds to pass through.

[0013] The beneficial effects of this invention are as follows: seeds are sucked from the hopper by several continuously rotating vacuum nozzles, and then the grain seeds adsorbed on each vacuum nozzle are scraped off one by one by the guide tube and led out of the hopper. The vacuum suction method can ensure that the seeds are not damaged, and can also ensure the consistency of grain seeds each time they are released, so as to achieve precise control of the number of seeds released.

[0023] Please see Figures 1 to 5According to a preferred embodiment of the present invention, a grain planting device includes a silo 10 for storing grain seeds, a rotating disk 20 disposed in the silo 10, a suction device 30 for suctioning grain seeds mounted on the rotating disk 20, and a guide pipe 40 disposed in the silo 10 for guiding the grain seeds suctioned by the suction device 20 out of the silo 10. The rotating disk 20 can rotate at high speed or at a constant speed relative to the silo 10, so that the suction device 30 can suction at least one grain seed, and the guide pipe 30 can scrape the suctioned grain seeds from the suction device 20 and guide them out of the silo 10. In specific implementation, the continuous rotation of the rotating disk 20 causes each suction device 30 to suction grain seeds in the silo 10, while the guide pipe scrapes the grain seeds suctioned by the suction device 30 from the suction device and guides them into the interior of the guide pipe 40 and out of the silo by the rotation of the rotating disk 20.

[0024] In this embodiment, the suction device 20 includes several vacuum nozzles 21 equidistantly arranged around the rotating disk 20 and at least one vacuum pump 22 providing vacuum suction to each vacuum nozzle 21. This allows the vacuum nozzles 21 to suck up at least one grain seed from the hopper 10, and then the grain seeds on the vacuum nozzles 21 are scraped off one by one and guided out of the hopper 10 through the guide tube 40. In this embodiment, the vacuum nozzle 21 can only suck up one seed at a time to ensure that the number of seeds released each time is consistent. Of course, in some embodiments, the vacuum nozzle 21 can also be configured to suck up two or more seeds; this can be achieved by simply adjusting the diameter of the suction port of the vacuum nozzle 21.

[0025] Specifically, in this embodiment, the hopper 10 has an inlet 11 and an outlet 12. The rotating disk 20 is rotatably mounted in the outlet 12 via an annular rotating assembly 50. The annular rotating assembly 50 includes an annular guide rail 51 and an annular slider 52 rotatably mounted on the annular guide rail 51. The rotating disk 20 is fixed on the annular slider 52 so that the rotating disk 20 can rotate on the annular guide rail 51 with the help of the annular slider 52.

[0026] Specifically, in this embodiment, the grain planting device includes a drive motor 60 for driving the rotating disk 20 to rotate. The drive motor 60 is fixed to the outside of the hopper 10 via a motor frame 61, and the motor shaft of the drive motor 60 is fixed to the rotating disk 20, thereby enabling the drive motor 60 to drive the rotating disk 20 to rotate.

[0027] Specifically, in this embodiment, the motor shaft of the drive motor 60 is fixed to the rotating disk 20 via a connecting pipe 62. Each vacuum nozzle 21 is connected to the connecting pipe 62 via an air pipe 211. The vacuum pump 22 is connected to the connecting pipe 62 so that the connecting pipe 62 and the air pipe are evacuated to a vacuum, ensuring that the vacuum nozzle 21 can perform suction operations. It is worth mentioning that one end of the connecting pipe 62 is provided with a connecting plate 621 fixed to the rotating disk 20, and the other end of the connecting pipe 62 is fixed to the motor shaft of the drive motor 60. The connecting plate 621 is provided with several air holes for connecting the air pipes to facilitate the connection of the air pipes. In fact, in order to ensure the stability of the rotation process, the air pipes are metal pipes or other rigid plastic pipes to prevent the air pipes from getting tangled during rotation.

[0028] Specifically, in this embodiment, the rotating disk 20 is provided with several mounting holes 201 for connecting the vacuum nozzle 21. A suction kit 23 is provided in the mounting holes 21. The suction kit 23 includes a cylindrical body 231 connected to the vacuum nozzle 21 and a soft body 232 provided at the end of the cylindrical body 231 for suctioning grain seeds. The top surface of the soft body 232 is a conical surface. The soft body 232 is provided with several through holes 232A that penetrate the cylindrical body 231, so that the vacuum nozzle can suction the grain seeds onto the soft body 232 when vacuuming. The area of ​​the soft body 232 determines the amount of grain seeds that are suctioned. The user can adjust the area of ​​the soft body 232 according to the size of the grain seeds to ensure the desired amount is suctioned.

[0029] Specifically, the guide tube 40 is fixed inside the hopper 10. One end of the guide tube 40 extends to the position of the rotating disk 20, and the other end of the guide tube 40 extends out of the hopper 10 and connects to other devices to ensure that the seeds drawn out enter the soil. The end of the guide tube 40 near the rotating disk 20 is provided with a notch 41 for the grain seeds to enter the tube. The size of the notch 41 is determined according to the size of the grain seeds to ensure that each grain seed sucked from the soft body 22 can enter the tube through the notch 41, and then the sucked grain seeds are scraped into the guide tube by the tube wall on the side corresponding to the notch.

[0030] The present invention aims to extract seeds from a hopper using several continuously rotating vacuum nozzles, and then scrape off the grain seeds adsorbed on each vacuum nozzle one by one through a guide tube and lead them out of the hopper. The vacuum extraction method can ensure that the seeds are not damaged while ensuring the consistency of grain seeds released each time, and achieve precise control of the number of seeds released.

[0031] The embodiments and accompanying drawings of this invention are merely for illustrating the design concept of this invention, and the scope of protection of this invention should not be limited to these embodiments.

[0032] As can be seen from the above description, the design objective of this invention can be effectively implemented. The embodiments illustrate the objectives of this invention, as well as the functional and structural subject matter, and include other equivalent substitutions.

[0033] Therefore, the scope of the invention includes other equivalent implementations, and the specific scope of the claims is as described in the claims.
