Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery component testing, specifically to a seed metering device for testing seed guide tubes. Background Technology

[0002] Due to structural limitations, corn and soybean planters have a long distance between the seeds after exiting the seed metering device and the seedbed. Therefore, a seed guide tube is needed as a guiding and protective component to ensure the seeds land smoothly on the seedbed. The angle of the seed guide tube directly affects the plant spacing after the seeds land. Currently, to obtain the appropriate seed guide tube angle, it is necessary to configure an entire single device to test the installation angle of the seed guide tube, which is labor-intensive and has low testing and sampling efficiency. Since different types of seed metering devices use different seed guide tubes, the installation angle of the seed guide tube also needs to be readjusted and tested when using different seed metering devices, and the visualization of the seed trajectory during testing is low.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] like Figure 1 and Figure 2As shown, a seed metering device for testing seed guide tubes includes a test frame 1, a speed-regulating conveying mechanism 2, and a seed metering control mechanism 3. The test frame 1 is a frame structure for installing components such as seed metering devices and seed guide tubes. The test frame 1 is equipped with a seed metering device mounting component 14 and a seed guide tube mounting component. The seed metering device mounting component 14 is used to install the seed metering device. The seed metering device mounting component 14 is located above the speed-regulating conveying mechanism 2. The seed metering device mounting component can be moved and adjusted along the conveying direction and width direction of the speed-regulating conveying mechanism 2, so that the installation position of the seed metering device is adjustable. The seed guide tube mounting component is used to install the seed guide tube. The seed guide tube mounting component is located above the speed-regulating conveying mechanism 2 and below the seed metering device mounting component 14. The position of the seed guide tube mounting component can be adjusted in the vertical and width directions of the speed-regulating conveying mechanism 2. The seed guide tube mounting component is provided with at least two seed guide tube hook positions along the conveying direction of the speed-regulating conveying mechanism 2. By adjusting the position of the seed guide tube on the seed guide tube mounting component and adjusting the position of the seed guide tube mounting component on the test frame 1, the position of the seed guide tube can be adapted to the seed metering device, and the seed guide tube can simulate various angle states.

[0019] The speed-adjustable conveying mechanism 2 is an adjustable-speed conveying device, preferably an adjustable-speed belt conveyor. The seed metering device discharges the seeds into the seed guide tube, and the seed guide tube leads the seeds out and onto the conveying surface of the speed-adjustable conveying mechanism 2. The speed-adjustable conveying mechanism 2 can simulate the seeder in a walking state to facilitate observation of plant spacing. When using a conveying device in the form of a belt conveyor, the conveying speed of the speed-adjustable conveying mechanism 2 is adjustable between 0-25 km / h.

[0020] The test frame 1 is also equipped with a seed metering control mechanism 3. This mechanism 3 incorporates a control system for various seed metering devices, including pneumatic and finger-clamp seed metering devices, making it compatible with a wide range of commercially available seed metering devices. The seed metering control mechanism 3 includes a control connection part. After the seed metering device and seed guide tube are installed on the test frame 1, the control mechanism 3 is connected to the seed metering device via this connection part, allowing for adjustment and control of the seed metering device. In some embodiments, an operating platform is provided on the test frame 1 at the seed metering control mechanism, facilitating debugging and maintenance of the mechanism using external equipment.

[0021] Please see Figure 2The test frame 1 is equipped with a first mounting beam 11, which is positioned along the conveying direction of the speed-regulating conveying mechanism 2. The first mounting beam 11 has a first mounting hole, which is a strip-shaped hole along the axial direction of the first mounting beam 11. The seed metering device mounting component 14 is plate-shaped and has a first waist hole. The seed metering device mounting component 14 is connected to the first mounting beam 11 via a first connector passing through the first waist hole and the first mounting hole. The first waist hole is along the width direction of the speed-regulating conveying mechanism 2. Through the first mounting hole, the seed metering device mounting component 14 can be moved and adjusted along the conveying direction of the speed-regulating conveying mechanism 2. Through the first waist hole along the width direction of the speed-regulating conveying mechanism 2, the seed metering device mounting component 14 can be moved and adjusted along the width direction of the speed-regulating conveying mechanism 2, thereby allowing the seed metering device mounting component 14 and the seed metering device mounted on it to freely adjust their installation position in the horizontal direction.

[0022] Multiple first waist holes can be provided on the seed metering device mounting component 14 to improve the installation strength of the seed metering device mounting component 14. Two first mounting beams 11 can also be provided, with the seed metering device mounting component 14 connected to multiple first mounting beams 11 to further improve the installation strength of the seed metering device mounting component 14. The first connecting member is preferably a bolt structure; tightening the first connecting member fixes the seed metering device mounting component 14 to the first mounting beam 11, while loosening the first connecting member allows adjustment of the position of the seed metering device mounting component 14.

[0023] Since the seed metering device is equipped with a drive motor, to improve the support strength of the seed metering device, the test frame 1 is also equipped with a second mounting beam 12 and a motor mounting plate 19. The second mounting beam 12 is parallel to the first mounting beam 11, and a second mounting hole is provided on the second mounting beam 12 along the axial direction. The motor mounting plate 19 is vertically arranged and has a second waist hole along the vertical direction. The motor mounting plate 19 is connected to the second mounting beam 12 through a second connector passing through the second mounting hole and the second waist hole. The motor mounting plate 19 is provided with a motor mounting position, which includes several motor connection holes. The motor is connected to the motor mounting plate 19 through connecting components such as screws. Through the second connection hole, the motor mounting plate 19 can be adjusted along the conveying direction of the speed-regulating conveying mechanism 2. Through the second waist hole, the motor mounting plate 19 can be adjusted up and down. Both the seed metering device mounting component 14 and the motor mounting plate 19 are adjustable, so that seed metering devices of various models and specifications can be installed on the test frame 1.

[0024] The test frame 1 is also provided with a third mounting beam 13, which is vertically arranged and has a third mounting hole along its vertical direction. The seed guide tube mounting component includes an upper bracket 15 and a lower bracket 17. The upper bracket 15 is provided with a third waist hole along the width direction of the speed-regulating conveying mechanism 2. The upper bracket 15 is connected to the third mounting beam 13 through a third connector passing through the third waist hole and the third mounting hole. The upper bracket 15 can be adjusted up and down and can also be adjusted along the width direction of the speed-regulating conveying mechanism 2. The upper bracket 15 is provided with an upper hanging member, which has at least two seed guide tube hanging holes 16 along the conveying direction of the speed-regulating conveying mechanism 2. The seed guide tube hanging holes 16 are the seed guide tube hanging positions. A hanging shaft is provided at the hanging point of the seed guide tube. The hanging shaft passes through a seed guide tube hanging hole 16 to hang the seed guide tube on the upper hanging frame 15. The seed guide tube can be adjusted in the height direction and the width direction of the speed-regulating conveying mechanism 2 by using the movable and adjustable upper hanging frame 15. By matching the hanging shaft at the hanging point of the seed guide tube with different seed guide tube hanging holes 16, the seed guide tube can be adjusted in the conveying direction of the speed-regulating conveying mechanism 2.

[0025] As an optional implementation, the upper bracket is provided with adjustment holes, which communicate with the hanging holes 16 of each seed guide tube. Using the adjustment holes, the hanging shaft can be matched with different seed guide tube hanging holes 16 without removing the hanging shaft from the upper bracket, so as to facilitate the adjustment of the angle of the seed guide tube.

[0026] The lower bracket 17 is provided with a fourth waist hole, which is along the width direction of the speed regulating conveying mechanism 2. The lower bracket 17 is connected to the third mounting beam 13 through a fourth connector passing through the fourth waist hole and the third mounting hole. The lower bracket 17 is provided with a lower support 18, and the seed guide tube is provided with a support part. The support part of the seed guide tube can cooperate with the lower support 18 so that the lower support 18 can support the seed guide tube.

[0027] Similar to the first connector, the second, third, and fourth connectors are all bolted structures.

[0028] During actual testing, the hanging shaft of the seed guide tube is passed through one seed guide tube hanging hole 16, and the supporting part of the seed guide tube is supported on the lower support 18, so that the seed guide tube is installed on the test frame 1. When it is necessary to adjust the angle of the seed guide tube, the hanging shaft of the seed guide tube is passed through another seed guide tube connecting hole. Since the supporting part of the seed guide tube is still supported on the lower support 18, the position of the supporting part of the seed guide tube does not change, thereby allowing the angle of the seed guide tube to be adjusted.

[0029] In a further embodiment, a seed metering monitoring device is installed on the test frame 1, located between the seed metering device mounting component 14 and the seed guide tube mounting component. Specifically, after the seed metering device and the seed guide tube are installed on the test frame 1 and aligned, the seed metering monitoring device is located at the junction of the seed metering device and the seed guide tube, and monitors the seed metering device's seeding of the seed into the seed guide tube. A seed dropping monitoring device is installed above the speed-regulating conveying mechanism 2, located below the seed guide tube mounting component. Specifically, the seed dropping monitoring device is located at the outlet of the seed guide tube, used to monitor the seed dropping of the seed into the speed-regulating conveying mechanism 2. The seed metering monitoring device and the seed dropping monitoring device are monitoring components such as cameras or industrial cameras, which can realize the visual recording of seed metering, seed dropping and other steps, facilitating later analysis and research.

[0030] A counting monitor can also be installed on the seed delivery tube to detect the seeding status inside the tube, further improving the testing results.
