Detailed implementation manners
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0023] Traditional seed spreaders often rely on mechanical force and gravity to distribute seeds and scatter the seeds into the soil by spreading. However, this spreading mechanism is difficult to accurately control the spreading quantity and position of the seeds, resulting in problems such as inconsistent number of seeds in each planting position or uneven distribution of seeds, which affects the growth of crop seedlings.
[0024] To solve the defects existing in the above seeder during the seeding process, please refer to Figures 1-5, a bean seeding machine provided by the utility model can accurately control the number of seeds and conveniently adjust the seeding position, improving the uniformity of seeding operations. The seeding machine is based on a frame 1, on which a support plate 2 is installed. At the bottom of the support plate 2, a plurality of equally spaced suspension rods 4 are installed. The lower end of the suspension rod 4 is fixedly connected to a seeding box 5. An adjusting mechanism 3 for adjusting the spacing between a plurality of seeding boxes 5 is provided on the support plate 2. The seeding spacing of the seeds can be adjusted through the adjusting mechanism 3. On one side of the top of the seeding box 5, a material cylinder 6 is installed for storing seeds. A circular groove 7 is opened inside the seeding box 5, and a material feeding mechanism 8 is arranged inside the circular groove 7 for sowing the seeds one by one, facilitating the control of the number of sown seeds. Among them, a distributing plate 81 rotatably installed inside the circular groove 7 is provided. A material hole 82 that can only accommodate one seed is opened on the distributing plate 81. A rotating shaft 85 is slidably connected to a plurality of distributing plates 81. Upper through grooves 89 and lower through grooves 83 are respectively opened at the top and bottom of the seeding box 5. A discharge pipe 84 communicating with the lower through groove 83 is also installed at the bottom of the seeding box 5. A feeding pipe is arranged at the bottom of the material cylinder 6, and the feeding pipe can also only accommodate one seed. The feeding pipe is communicated with the upper through groove 89. The seeds in the material cylinder 6 enter the material hole 82 through the feeding pipe and the upper through groove 89. The rotation of the rotating shaft 85 can drive the rotation of a plurality of distributing plates 81. The rotation of the distributing plate 81 drives the material hole 82 to rotate to the position of the lower through groove 83. One seed in the material hole 82 can roll from the lower through groove 83 into the discharge pipe 84 and fall onto the planting position along the discharge pipe 84. The distributing plate 81 continues to rotate until the material hole 82 is aligned with the feeding pipe of the material cylinder 6, and the material hole 82 can catch another seed. Similarly, another seed can be sown onto the planting position. Each time the distributing plate 81 rotates one circle, one seed can be sown, facilitating the control of the number of seeds. Moreover, the rotating shaft 85 can drive a plurality of distributing plates 81 to rotate synchronously, so that the discharge of a plurality of discharge pipes 84 can be synchronized, ensuring the consistency of the sowing quantity and speed of a plurality of seeding boxes 5.
[0025] The above-mentioned blanking mechanism 8 can control the number of seeds sown in the sowing box 5. In order to conveniently adjust the sowing spacing of the seeds on this basis, it is necessary to conveniently control the spacing between multiple sowing boxes 5. Therefore, the adjusting mechanism 3 is set as an electric push rod 31 fixedly installed at the end of the support plate 2. The free end of the electric push rod 31 is fixedly connected with a push-pull plate 32. A connecting rod 33 is installed on the push-pull plate 32. The upper end of the hanging rod 4 is fixedly connected with a connecting seat 34. The end of the connecting seat 34 is slidably sleeved on the connecting rod 33. A plurality of sliding grooves 35 for the hanging rod 4 to slide are opened on the support plate 2. The plurality of sliding grooves 35 are divided into two groups. The two groups of sliding grooves 35 are symmetrically distributed about the center line of the support plate 2, and the inclination angles of the plurality of sliding grooves 35 in the same group gradually increase from the inside to the outside. Driving the electric push rod 31 drives the push-pull plate 32 to move. The movement of the push-pull plate 32 drives the connecting seat 34 on the connecting rod 33 to move. The connecting seat 34 drives the hanging rod 4 to slide along the sliding groove 35. At the same time, the connecting seat 34 can slidably adapt on the connecting rod 33. The hanging rod 4 slides along the path of the sliding groove 35 to realize the contraction and expansion of the plurality of hanging rods 4, that is, the spacing between the plurality of sowing boxes 5 can be changed, so that the spacing of the sowing positions can be controlled.
[0026] When the spacing of the sowing boxes 5 is adjusted, it will drive the sowing boxes 5 to slide on the material distribution plate 81. Therefore, the material distribution plate 81 needs to slide on the rotating shaft 85. Convex strips 88 are symmetrically arranged outside the rotating shaft 85. A clamping groove 810 adapted to the convex strips 88 is opened on the inner wall of the material distribution plate 81. This can meet the sliding of the material distribution plate 81 on the sowing box 5, and the rotating shaft 85 can also drive the material distribution plate 81 to rotate when it rotates. Circular holes with a diameter larger than the rotating shaft 85 are opened on both sides of the sowing box 5, which can provide a rotating space for the convex strips 88 when the rotating shaft 85 rotates.
[0027] In order to realize the automatic blanking of the sowing box 5, sliding rods 86 are slidably connected to both sides of the bottom of the support plate 2. The rotating shaft 85 is rotatably installed between the two sliding rods 86, and a servo motor 87 acting on the rotating shaft 85 is fixedly installed on the side of one of the sliding rods 86. Since the spacing of the sowing boxes 5 needs to slide back and forth at the bottom of the support plate 2 when it changes, the setting of the sliding rods 86 can make the servo motor 87 and the rotating shaft 85 slide back and forth following the sowing box 5. Driving the servo motor 87 can drive the rotating shaft 85 to rotate, and then drive a plurality of material distribution plates 81 to rotate, realizing the effect of automatic blanking of multiple sowing boxes 5 one by one at the same time.
[0028] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.
[0029] It should be noted that in this text, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
