Description

Technical Field

[0001] This utility model relates to the field of rotating support technology, and in particular to a corn seed selection device. Background Technology

[0002] Seed selection is a crucial step in corn cultivation. Choosing seeds with high purity and high vigor ensures the genetic stability of the variety, while high vigor results in higher germination and seedling rates, promoting uniform and complete seedling emergence and laying the foundation for high yields.

[0003] In existing technologies, corn seed selection devices cannot control the amount of seeds selected at one time. If the amount of seeds selected at one time is too large, it will cause mutual squeezing and friction between seeds during the selection process, thereby damaging the seeds, reducing the germination rate, and thus affecting the yield and quality of corn. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing traditional corn seed selection devices, which cannot control the amount of seeds selected at one time. Excessive selection at one time can lead to mutual squeezing and friction between seeds during the selection process, thereby damaging the seeds, reducing the germination rate, and thus affecting the yield and quality of corn. Therefore, this invention proposes a corn seed selection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a corn seed selection device, comprising a base plate, a rotating device at the top of the base plate, the rotating device comprising a housing, the bottom end of the housing being fixedly connected to the base plate, two arc-shaped plates being fixedly connected inside the housing, a seed storage hopper being fixedly connected to the outer sides of the two arc-shaped plates, a drive motor being fixedly connected to the outside of the housing, a round rod being fixedly connected to the output end of the drive motor, the arc surface of the round rod being rotatably connected to the housing, a component rod being fixedly connected to the arc surface of the round rod, two vibration motors being fixedly connected inside the housing, and seed selection plates being fixedly connected to the output ends of the two vibration motors.

[0006] The aforementioned components achieve the following effects: the drive motor's starting output drives the round rod to rotate, the round rod drives the component rod to rotate, and the vibration motor's starting output drives the seed selection plate to vibrate.

[0007] Preferably, the outer surface of the shell is fixedly connected to two support plates, and one side of the two support plates is fixedly connected to the seed storage hopper.

[0008] The aforementioned components achieve the following effect: the support plate supports the seed storage hopper, preventing deformation of the seed storage hopper.

[0009] Preferably, a support frame is fixedly connected to the outside of the housing, a guide hopper is fixedly connected to one side of the support frame, and one side of the guide hopper is fixedly connected to the housing.

[0010] The effect achieved by the above components is to support the guide hopper with the support frame and prevent the guide hopper from deforming.

[0011] Preferably, the interior of the housing is provided with a cleaning device, which includes two concave plates. The two concave plates are fixedly connected to the housing on opposite sides, and a movable plate is slidably connected inside the concave plates.

[0012] The effect achieved by the above components is that the moving plate slides within the concave plate.

[0013] Preferably, a connecting plate is fixedly connected to one side of the two movable plates that are close to each other, and two telescopic rods are fixedly connected to one side of the connecting plate.

[0014] The effect achieved by the above components is that the moving plate moves, causing the connecting plate to move, which in turn moves the telescopic rod.

[0015] Preferably, a cleaning plate is fixedly connected to the output end of the two telescopic rods, and one side of the cleaning plate is slidably connected to the seed selection plate.

[0016] The effect achieved by the above components is that the movement of the telescopic rod drives the movement of the cleaning plate.

[0017] Preferably, the arc surface of the telescopic rod is fitted with a spring, and the two ends of the two springs are respectively fixedly connected to the connecting plate and the cleaning plate.

[0018] The effect achieved by the above components is to prevent the spring from deforming during the stretching or contraction process.

[0019] Preferably, a pin is slidably connected to one side of the movable plate.

[0020] The effect achieved by the above components is that the pin and the movable plate are compatible.

[0021] Preferably, the arc surface of the pin is slidably connected to a limiting block, and one side of the two limiting blocks is fixedly connected to the housing.

[0022] The effect achieved by the above components is that the pin and the limit block are matched.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] In this invention, a rotating device is used to control the amount of corn seeds selected at one time. The drive motor starts and drives the round rod to rotate, and the weighting rod puts the corn seeds to be selected from the seed storage hopper onto the seed selection plate. The rotating device solves the problem that traditional corn seed selection devices cannot control the amount of seeds selected at one time. If the amount of seeds selected at one time is too large, it will cause mutual squeezing and friction between seeds during the selection process, thereby damaging the seeds, reducing the germination rate, and thus affecting the yield and quality of corn.

[0025] In this invention, when it is necessary to clean the corn seeds remaining on the seed selection plate, the moving plate drives the connecting plate to move, causing the telescopic rod and spring to move. The cleaning plate then slides on the seed selection plate, thus removing the corn seeds. This cleaning device solves the problem that traditional corn seed selection devices are not convenient for cleaning the seed selection plate, resulting in corn seeds remaining on the seed selection plate and affecting the seed selection effect.

[0032] The specific setup and function of the rotating device 2 and the cleaning device 3 will be described in detail below.

[0033] Reference Figure 2As shown in this embodiment: the rotating device 2 includes a housing 201, the bottom end of which is fixedly connected to the base plate 1. Two arc-shaped plates 202 are fixedly connected inside the housing 201, and a seed storage hopper 205 is fixedly connected to the outer side of the two arc-shaped plates 202. A drive motor 211 is fixedly connected to the outside of the housing 201. A round rod 204 is fixedly connected to the output end of the drive motor 211, and the arc surface of the round rod 204 is rotatably connected to the housing 201. A component rod 203 is fixedly connected to the arc surface of the round rod 204. Two vibration motors 206 are fixedly connected inside the housing 201, and a seed selection plate 207 is fixedly connected to the output end of the two vibration motors 206. This achieves the effect that the drive motor 211, when started, drives the round rod 204 to rotate, which in turn drives the component rod 203 to rotate, and the vibration motors 206, when started, drive the seed selection plate 207 to vibrate. Two support plates 210 are fixedly connected to the outside of the housing 201, and one side of each support plate 210 is fixedly connected to the seed storage hopper 205. The support plate 210 supports the seed storage hopper 205, preventing deformation of the seed storage hopper 205. A support frame 209 is fixedly connected to the outside of the shell 201. A guide hopper 208 is fixedly connected to one side of the support frame 209, and one side of the guide hopper 208 is fixedly connected to the shell 201. This achieves the effect of the support frame 209 supporting the guide hopper 208, preventing deformation of the guide hopper 208.

[0034] Reference Figure 4 As shown, in this embodiment: the cleaning device 3 includes two concave plates 31. The sides of the two concave plates 31 that are far apart from each other are fixedly connected to the housing 201. A movable plate 32 is slidably connected inside the concave plates 31, achieving the effect of the movable plate 32 sliding within the concave plates 31. A connecting plate 33 is fixedly connected to the sides of the two movable plates 32 that are close to each other. Two telescopic rods 34 are fixedly connected to one side of the connecting plate 33, achieving the effect of the movable plate 32 moving, driving the connecting plate 33 to move, and thus moving the telescopic rods 34. A cleaning plate 36 is fixedly connected to the output end of the two telescopic rods 34, and one side of the cleaning plate 36 is slidably connected to the seed selection plate 207, achieving the effect of the telescopic rods 34 moving, driving the cleaning plate 36 to move. A spring 35 is sleeved on the arc surface of the telescopic rod 34, and the two ends of the two springs 35 are fixedly connected to the connecting plate 33 and the cleaning plate 36 respectively. This achieves the effect of the telescopic rod 34 preventing the springs 35 from deforming during the stretching or contraction process. A pin 37 is slidably connected to one side of the movable plate 32. This achieves the desired fit between the pin 37 and the movable plate 32. The arc surface of the pin 37 is slidably connected to the limiting block 38, and one side of each limiting block 38 is fixedly connected to the housing 201. This achieves the desired fit between the pin 37 and the limiting block 38.

[0035] Working principle: By using the rotating device 2, when it is necessary to control the amount of corn seeds selected at one time, the operator first puts the corn seeds to be selected into the seed storage hopper 205, starts the vibration motor, and the output end of the vibration motor 206 drives the seed selection plate 207 to vibrate. Then, the drive motor 211 is started, and the output end of the drive motor 211 drives the round rod 204 to rotate. The rotation of the round rod 204 drives the distribution rod 203 to rotate, so that the distribution rod 203 distributes the amount of corn seeds to be selected in the seed storage hopper 205 onto the seed selection plate 207. The qualified corn seeds are screened out from the seed selection plate 207, and the unqualified corn seeds are discharged from the guide hopper 208. By using the rotating device 2, the problem of traditional corn seed selection devices being unable to control the amount of seeds selected at one time, and the problem of excessive amount of seeds selected at one time causing mutual squeezing and friction between seeds during the selection process, thereby damaging the seeds, reducing the germination rate, and thus affecting the yield and quality of corn is solved.

[0036] When it is necessary to clean the corn seeds remaining on the seed selection plate 207 using the cleaning device 3, the operator first pulls the pin 37 to release the pin 37 from its limit on the moving plate 32, and then pulls the moving plate 32 to slide within the concave plate 31. Simultaneously, the moving plate 32 moves the connecting plate 33, which in turn moves the telescopic rod 34 and the spring 35. The movement of the telescopic rod 34 and the spring 35 causes the cleaning plate 36 to slide on the seed selection plate 207, thereby removing the corn seeds remaining on the seed selection plate 207 and completing the cleaning of the seed selection plate 207. The cleaning device 3 solves the problem of traditional corn seed selection devices being inconvenient for cleaning the seed selection plate 207, resulting in corn seeds remaining on the seed selection plate 207 and affecting the seed selection effect.
