Preferably, the connecting hole on the mounting plate is arranged in a long groove shape, and the length direction of the connecting hole is in a vertical direction, so that the mounting height of the mounting plate on the frame can be conveniently adjusted, and the purpose of adjusting the height of the seed sowing device 7 is realized.
A connection surface 6 is provided at the lower end of the test carrier 1, and a specific traction area is provided on the connection surface 6, which traction area is used for simulating the installation position of the travelling wheel of the seeder. An adjusting mechanism 2 is connected to the traction area of the connecting surface 6 of the test carrier 1, and the lower end of the adjusting mechanism 2 is connected to the bracket 3.
The adjusting mechanism 2 can adopt a structure comprising a joint bearing and an adjustable bolt, and both ends of the adjustable bolt are connected with the joint bearing. The joint bearing at one end of the adjusting mechanism 2 is connected with the connecting area on the test carrier 1. So as to realize the purposes of adjusting parameters such as the inclination angle, the front and back positions and the like of the test carrier 1 and further simulating various working conditions in actual seeding operation.
A transfer mechanism 4 is provided at the lower end of the support 3, and this transfer mechanism 4 is located below the test carrier 1. The seeding surface 5 corresponding to the sowing direction of the seed sowing device 7 is arranged on the conveying mechanism 4, the seeding surface 5 corresponds to the broadcasting port of the seed sowing device 7 on the test carrier 1, the seeding surface 5 simulates the surface of farmland soil, and the distribution condition of the dropping points of seeds of the seed sowing device 7 in actual working can be dynamically displayed. So as to observe and record key performance indexes such as the position, the grain number, the spacing and the like of the seed put in the seed sowing device 7.
The sowing surface 5 on the conveying mechanism 4 corresponds up and down to the connecting surface 6 on the test carrier 1. The relative position relationship between the seed metering device 7 and the seeding surface 5 on the test carrier 1 is changed by operating the adjusting mechanism 2, so that the gesture of the seed metering device 7 on the working surface under different working conditions can be simulated.
Through this structure, at least the following beneficial effect is reached:
① The test system can perform accurate simulation according to various complex working conditions in actual agricultural seeding operation, is beneficial to evaluating the seeding performance of the seed metering device 7 under different conditions, and improves the accuracy and the effectiveness of test results.
② The test carrier 1 can be suitable for installing seed metering devices 7 of various types and structures, and has good universality and interchangeability.

Illustratively, to facilitate simulating the performance of the seed meter 7 under ideal conditions where the work floor is level and the work floor elevation angle is 0 °. In this embodiment, the operator can lower or raise the test carrier 1 and the seed metering device 7 in its entirety to a proper position by rotating or moving the control part (e.g., screw, hydraulic cylinder, etc.) of the adjusting mechanism 2, and ensure that the mounting surface of the test carrier 1 remains parallel to the sowing surface 5 on the conveying mechanism 4. The seeding device 7 can simulate seeding operation under ideal farmland environment, namely the working ground is flat and has no gradient, which is helpful for accurately evaluating the performance index of the seeding device 7 under the optimal condition.
Illustratively, to facilitate simulating the performance of the seed meter 7 in a situation where the work floor is level but there is an incline in the direction of travel. In this embodiment, the operator can make a specific angular adjustment of the test carrier 1 by means of the adjustment mechanism 2. A specific operation may be to use the bidirectional synchronous motion function of the adjusting mechanism 2 so that two corners of one end of the mounting surface (typically, the front end or the rear end of the travel direction of the seed metering device 7) can be simultaneously and proportionally moved toward or away from the sowing surface 5 to be simulatively inclined toward one direction. For example, if the condition of the front ground descent (downhill) is to be simulated, the front end of the test carrier 1 can be tilted downward by the adjusting mechanism 2; conversely, if the front ground is simulated to rise (climb), the front end is tilted upward. Therefore, the relative angle relation between the seed metering device 7 and the inclined ground can be accurately set according to actual requirements, and the working performance of the seed metering device 7 under the non-horizontal terrain can be truly reflected. By this structure, on the one hand, the actual farmland working environment can be highly simulated, and especially for those fields which are not perfectly flat, it is helpful to more accurately evaluate and optimize the sowing effect of the seed sowing device 7 under different inclination conditions. On the other hand, through the performance test of the seed metering device 7 under various inclined ground working conditions, the design of the seed metering device 7 can be improved according to different geographic and geomorphic characteristics, and the adaptability and the working efficiency of the seed metering device 7 under complex terrain conditions are improved.
Illustratively, to facilitate simulating the performance of the seed meter 7 under conditions where the work surface is level but inclined from side to side in the direction of travel (e.g., hillside seeding). In this embodiment, the operator will adjust the angle of the mounting surface of the test carrier 1 by means of the adjustment mechanism 2. Specifically, the two corners of one side (e.g., the right side) of the mounting surface can be moved toward or away from the sowing surface 5 in synchronization with the adjusting mechanism 2 to simulate the situation in which the right-side ground surface is gradually raised or lowered. For example, if the condition of the right side descent of the ground is to be simulated, the right side of the test carrier 1 can be tilted downward by the adjusting mechanism 2; conversely, if the simulated right floor rises, the right side is tilted upward. Therefore, the relative angle relation between the seed metering device 7 and the inclined ground can be accurately set according to actual requirements, and the working performance of the seed metering device 7 under the non-horizontal terrain can be truly reflected. Through this structure, on the one hand, this technical scheme can accurate simulation actual farmland operation in common slope topography seeding scene for the test result is close to real condition more, helps improving the work adaptability and the reliability of seed metering ware 7 under complicated field environment. On the other hand, precious data support and reference can be provided for product design by simulating the performance of the seed metering device 7 under different gradient conditions, so that manufacturers can pertinently improve the structure and the function of the seed metering device 7 according to test results, and the seeding precision, the uniformity and the working efficiency of the seed metering device on inclined ground are improved.
Illustratively, to facilitate simulating performance of the seed meter 7 under uneven working conditions of the working surface, in this embodiment, an operator adjusts the mounting surface of the test carrier 1 through the adjusting mechanism 2 to form a specific angle with the sowing surface 5. Specifically, when it is desired to simulate an uneven working surface, such as a high or low ground at a certain angle, the height position of one angle (such as the left or right angle) on the mounting surface can be individually changed by the adjusting mechanism 2 to approach or separate from the sowing surface 5 so as to simulate the topographical features of different slopes and undulations.
For example, if a large bump is to be simulated on the left side of the front end of the working surface or if the front end is slightly higher on the left side of the terrain, the left corner of the front end of the mounting surface can be raised to enable the seed sowing device 7 to perform a sowing test under the simulated working condition.
If the left side of the front end of the working surface is to be simulated, a pit is arranged or the left side of the front end is slightly lower, the left corner of the front end of the mounting surface can be lowered, so that the seeding device 7 can perform seeding test under the condition of simulating the working condition.
If the right side of the front end of the working surface is to be simulated, a large-sized bump or a slightly higher terrain is arranged on the right side of the front end, the right corner of the front end of the mounting surface can be lifted, so that the seeding apparatus 7 can perform seeding test under the condition of simulating the working condition.
If the right side of the front end of the working surface is to be simulated, a pit is arranged or the right side of the front end is slightly lower, the right angle of the front end of the mounting surface can be reduced, so that the seeding device 7 can perform seeding test under the condition of simulating the working condition.
The simulation of the left and right sides of the rear end is similar. And will not be traced again here.
Through the structure, on one hand, various uneven topography in the farmland is simulated, so that the performance test of the seed sowing device 7 is closer to the actual operation environment, and the reliability of the test result is improved. On the other hand, the weakness and the advantage of the seed metering device 7 under the condition of complex terrain can be found through the detailed test of the working performance of the seed metering device 7 on the simulated uneven ground, the basis is provided for improving and optimizing the design of the seed metering device 7, and the adaptability and the stability of the seed metering device in practical application are improved.
Illustratively, to facilitate simulating the performance of the seed meter 7 under uneven work conditions. In this embodiment, the operator can adjust the distance between two angles at one end (e.g., front end or rear end) of the mounting surface and the sowing surface 5 according to the fluctuation of the actual terrain, so that one angle approaches the sowing surface 5 to simulate an ascending slope (e.g., hills or piles), and the other angle approaches the sowing surface 5 to simulate a descending slope (e.g., ravines or depressions). An irregular terrain condition similar to that in a real farmland is formed, and truly reflects the situation when the seed metering device 7 performs seeding operation on the ground with different inclinations. Through this structure, on the one hand, this technical scheme can realize the accurate simulation to complicated topography condition, ensures that the performance test of seed metering ware 7 under various actual conditions has high authenticity, helps evaluating its adaptability and the accuracy of sowing on uneven ground. On the other hand, through careful analysis of the working performance of the seed metering device 7 under various uneven terrains, improved data can be obtained, so that the structure of the seed metering device 7 is optimized in a targeted manner, and the performance of the seed metering device in a complex farmland environment is improved.
Illustratively, to facilitate simulating the performance of the seed meter 7 under uneven work conditions. In this embodiment, the operator can independently adjust the two corners of one side of the mounting surface using the adjustment mechanism 2 such that one corner is closer to the sowing surface 5 to simulate a terrain elevation (e.g., hills or piles) and the other corner is farther from the sowing surface 5 to simulate a terrain depression (e.g., ravines or depressions). So as to simulate various complex terrains existing in a real farmland and ensure that the seed metering device 7 can perform effective performance evaluation under different terrains. Through this structure, on the one hand, can realize the fine simulation to complicated farmland topography, ensure that seed metering ware 7 performance test result is closer to real field operating mode. On the other hand, through carrying out intensive study on the seeding performance of the seed metering device 7 under different inclinations, potential design problems can be found out, the structure and the function of the seed metering device 7 are improved accordingly, and the adaptability and the working efficiency of the seed metering device under various terrain conditions are improved.
