The testing machine comprises a machine frame, a seed metering device mounting rack and a traveling wheel, a traveling guide rail is arranged on the testing platform, the traveling wheel of the testing machine is matched with the guide rail, the traveling seed dispersing groove of the seed metering device is arranged on the corresponding position of the testing platform under the seed metering device mounting rack, and the traveling route of the seed dispersing groove and the seed metering device are identical. The structure of the utility model is simple, the testing is direct viewing and convenient, the seed dispersing groove can accurately simulate the practical sowing situation of the duck bill drum type dibbling seed metering device in particular, the simulating level is high, the utility model is quite applied for the detecting of the drum-type seed metering device adopted during the planting of most of crops such as cotton, corn and sugar beet, etc., and the utility model not only can be used for the experimental investigation of agricultural colleges and scientific research academies to the service behavior of the seed metering device, but also can be used for the examination of the mass production and the overhaul of the seed metering device.
Description
Technical field:
The utility model relates to a kind of sower seeding unit testing stand.
Background technology:
Along with applying of precision film spreading seeding machine, aborning the quality inspection of its core component seeding unit, the maintenance in the use be the advanced and applicable special-purpose experimental bench of active demand all.
At present both at home and abroad seeding unit testing stand kind is a lot, but the seeding of all inapplicable drum-type dibbler experiment, has seriously restricted the promotion rate and the popularization scale of precision sower.
Chinese patent 85201873 disclosed vegetables seeding unit testing stands, the computer vision seeding unit testing stand that CN2777527 announces, all mainly by test-bed, plant the bed conveyer belt, the seeding unit installing rack, the conveyer belt oiling station, source of the gas, transmission mechanism, detection and surveillance and computer data processing system constitute, also comprise the shooting sensor-based system, mechanism is very complicated, cost is very high, its test principle is to sow on conveyer belt in oiling on the conveyer belt and with seed, seed is at the volley the conveyer belt of falling, because effect of inertia, simulation has error with the real work situation, thereby experiment effect is bad.
Summary of the invention:
The purpose of this utility model provide a kind of simple in structure, test intuitive and convenient, the shape degree height of walking back and forth, be primarily aimed at bunch planting formula sower seeding unit, especially the sower seeding unit testing stand of the seeding of the duckbilled drum-type bunch planting seeding unit test and the demand of detection.
The utility model is made up of test platform and testing machine, be characterized in that described testing machine comprises frame, seeding unit installing rack and travel wheel, described test platform is provided with the guide rail of advancing, and the travel wheel of described testing machine matches with the guide rail of advancing, the test platform of corresponding site is provided with the seeding unit cloth kind groove of advancing under the seeding unit installing rack, and this cloth kind groove when advancing with testing machine the course of seeding unit consistent.
As further improvement, the above-mentioned seeding unit trench bottom of advancing preferably is provided with the soft matting layer in surface, and above-mentioned matting layer is preferably the matte cloth of low elastic force.
For adapting to the test of air inhaling type fine sowing device, on above-mentioned frame, preferably be provided with negative-pressure air fan and blower fan drive motors.
As further improvement, the utility model preferably is provided with advance drive motors and stroke limit mechanism, described stroke limit mechanism comprises and is located at the limited block in the course on the test platform, be provided with the touch type limit switch on testing machine, the contact of described touch type limit switch is located in the control circuit of the drive motors power supply of advancing.
Compared with prior art, the utility model is simple in structure, the experiment intuitive and convenient, be primarily aimed at bunch planting formula sower seeding unit, especially be provided with the cloth kind groove sowing actual conditions of profiling duckbilled drum-type bunch planting seeding unit exactly, the shape degree height of walking back and forth, be highly suitable for the detection of the drum-type seeding unit that adopts in most of proportion of crop plantings such as cotton, corn, beet, can do simultaneously to slide cutter or two disk as the parts that bury, external force such as dependence chain allow the dibbler central shaft rotate the performance test of the seeding unit of realizing seeding.This seeding unit testing stand not only can be used for the experimental study to the seeding unit service behaviour of agricultural universities and colleges, scientific research institute, also can be used for the large-scale production check and in the seeding unit service work.
