Description

The utility model relates to the field of monitoring the sowing of seeds of tilled crops, and may find application in the conduct of research and testing of tilled sowing devices of tilled seeders of any designs and modifications.

A stand for testing seeding machines is known (see RU No. 49674 U1, A01G 7/00, publ. 10.12.2005), containing in its design a concrete platform, a rotating air-transmitting unit, a control panel, a direct-current electric motor for a drive of the seeding unit.

The disadvantages of the known devices are cumbersome structures, expressed in the concrete base of the sandy track. The complexity of the interaction of the components of the stand is expressed in the absence of a direct connection of the fixing device with a personal computer does not provide an opportunity to simulate the topography of the soil field.

The closest to the proposed test bench is a device for testing seed devices for precision seeding seeders (see RU No. 2356210 C1, А01С 7/00, publ. 27.05.2009), containing a drive station, a set of sensors and a recording device.

The disadvantages of this stand is the presence of an acoustic sensor that can detect not only the fallen seeds, but also vibration during the operation of the stand. Also, the design features of this type of sensors do not allow their installation directly in the sowing apparatus near the point of discharge of seeds from the sowing disc.

The task of the utility model is to improve the accuracy of determining the parameters (uniformity of seeding, seeding rate, etc.) and modes

the work of the sowing apparatus of precision seeding planters in the laboratory, increasing productivity during testing.

The essence of the utility model lies in the fact that the stand for testing and running-in of pneumatic sowing machines for row tillers, containing a frame on which the electric motor is placed, a vacuum unit with a vacuum depth regulator, sensors, a personal computer, further comprises a frequency converter for adjusting the revolutions of the electric motor and conveyor adhesive tape type, connected directly to the motor shaft and set in motion simultaneously with the sowing apparatus, sensors are used photoresist Ore, directly connected to a personal computer via information transfer cables.

The technical result is to increase the accuracy of determining the parameters (uniformity of seeding, seeding rate, etc.).

To achieve this technical result in the test bench for testing and running-in of pneumatic sowing devices of row crop drills, special sensors are used that are directly connected to a personal computer for registering the modes, parameters and results of the operation of the device.

Distinctive features of the stand from the above, closest to him:

the presence of a frequency converter with the ability to set the exact speed, which corresponds to the different modes of operation of the seeder during its operation;

the presence of a set of photoresistor sensors to determine the parameters and modes of operation of the sowing apparatus, quickly transmitting information to a personal computer;

the ability to adjust the sowing apparatus on the stand at the height from the surface of the adhesive conveyor-type tape, depending on the design features of the sowing apparatus;

additional screen for outputting operational data on parameters, modes and indicators of the seeding unit

the presence of a vacuum unit with the possibility of the depth of discharge of the vacuum chamber of the sowing apparatus and compressor.

Due to the presence of these signs, it is possible to fine-tune the operating modes of the sowing apparatus and imitate the conditions of its possible real work in the field, and with the help of sensors, the readings of its operation are promptly taken and the finished results are output to a PC using a special computer program.

The essence of the utility model is illustrated in the drawing, which shows a general view of the stand for testing and running-in of pneumatic sowing machines of row crop seeders.

The bench for testing the metering unit consists of a frame 1 with the following elements fixed on it: a DC motor 2, directly connected by a drive chain 3 to the metering machine 5 being tested, a frequency converter 4 for adjusting the motor speed, a vacuum unit 6 with a vacuum regulator, an air supply unit (air compressor) 7, photoresistor sensors 8, fixing the gathering of seeds from the sowing apparatus and their speed, i.e. for registration of the current modes and parameters of operation of the device, a personal computer 9 and an adhesive tape of conveyor type 10 for collecting seeded seeds.

The bench works as follows: when the power source is turned on, the indicator panel of the frequency converter 4 sets the required number of revolutions of the sowing unit 5 (set from the condition of the seeder operation); by pressing the start button on

the control unit of the frequency converter 4 starts up the electric motor 2 of the installation and thereby the chain device 3 connected with the shaft of rotation of the sowing unit 5 comes into rotation; the DC motor 2 and the adhesive tape 10 of the conveyor type (the tape collecting the sown seeds) are set in motion simultaneously, because have a common shaft. After that, the vacuum unit 6 of the sowing apparatus with a predetermined depth of discharge is activated. In the presence of seeds coming from the disc of the sowing apparatus, the photoresistor sensors 8 start fixing the set parameters and modes, the photoresistor sensors 8, directly connected to the personal computer 9, promptly process the results and output them in a special program to the personal computer.

This happens as follows: photoresistor sensors 8 are directly connected to the personal computer 9 by means of information transfer cables, on the screen of which, with the help of a special program, we get the finished result in the form of data on the presence of seeds, the number of twins, passes, etc.

If the setting of the pneumatic planter is required in height from the surface of the adhesive conveyor belt 10 during the operation of the planter, by stopping the stand, the bolt joints of the seeding apparatus are loosened and the required distance from the seed separation point from the seeding pneumatic planter to the surface of the adhesive conveyor tape 10 imitation furrows fields).
