UA19336U - Test bench for determining the quality of sowing seeds - Google Patents

Abstract

The proposed test bench for determining the quality of sowing seeds contains a support frame, the casing of a sowing mechanism with hopper for seeds, a rotary disk, a support disk, a conical drum with concentric chambers, which is installed at a vertical shaft, a drive for the drum, an optical measuring system, and a control unit. The casing of a sowing mechanism is installed at the guide parts of the frame, over the rotary disk, with a possibility to be radially displaced relative to the center of the disk. The rotary disk is supported by the support disk via support rollers. Between the casing of a sowing mechanism and the rotary disk, a screen with holes of 2 x 2 mm us installed, which is optically coupled with the optical measuring system. The amount of seeds, distance between seeds, and other parameters that characterize the quality of sowing seeds are determined by the measuring system connected to a computer.

Description

Description of the invention

The useful model refers to agricultural engineering and can be used for 2 studies of the quality characteristics of precision seed drills: this is the accuracy of seed placement in a row, deviation from the norm of sowing per unit area, their damage, the effect of the speed of movement of the unit on the quality of sowing, etc.

A well-known stand for researching the quality of seed sowing, which is made in the form of a frame, a housing of a seeding device with a seed hopper, a conical drum with concentrically placed cells on the periphery of its lower base with a vertical drive shaft, a drive and a control panel (Stand for researching 70 characteristics of precision sowing devices seeds. Gevko B.M., and others. Application for utility model Mo)200604085 dated 04/13/2006|.

The main disadvantage of the stand is limited technological capabilities and low labor productivity.

The basis of the useful model is the task of increasing labor productivity when conducting research on the characteristics of sowing devices and expanding technological capabilities by implementing a stand for 72 studies of the quality of seed sowing in the form of a frame, a body of a sowing device with a seed hopper, a conical drum with cells concentrically placed on the periphery of its lower base with a vertical drive shaft, a drive and a control panel, and the housing of the sowing device with a hopper is installed above the turntable on guides with the possibility of radial movement to the center, in turn, the guides are rigidly installed in the lower part of the frame, in which the drive mechanism is installed under the turntable, in addition, the lower end of the rotary disk is in interaction with the lower support disk through the rolling elements placed on its periphery in cylindrical grooves, and a sensitive optical screen is installed on top of the rotary disk, on top of which a grid with 2x2mm squares is installed, optical the sensitive screen through the converter is connected to the computer system for measuring the supply, the number of seeds, the distance between them, the accuracy of sowing, etc.

The stand for testing the quality of sowing seeds is shown in Fig. 1, Fig. 2 - view along A in Fig. 1, Fig. 3 - view along 29 B and Fig. 2. -

The stand for studying the quality of sowing seeds consists of frame 1 on which the main nodes are installed. On the left side of the frame 1, a seeding device with a hopper 2 is rigidly installed, in the middle of which a conical drum 4 is mounted on dovetail-type guides 3, with the possibility of radial movement, and cells 5 are concentrically placed along the periphery of its lower base. The conical drum 4 is mounted on a vertical ee , the drive shaft 6 with the electric motor 7. Under the cell 5, a window is made for moving the seeds to the sowing zone. co

Guides C are rigidly fixed to the frame 1, inside which a support disk 9 is rigidly mounted on supports 8, which interacts with the lower end of the rotary table 11 through the rolling elements 10. A sensitive optical screen 12 is installed on top of the rotary table o, which is connected to the computer by the computer system 13 through the converter 14. Ge")

The rotary table 11 is driven by an individual motor 15, and the research process is controlled from the control panel 16. The movement of the sowing device with the hopper 2 is carried out along the guides З - the dovetail 17 with fixing bolt 18. In addition, a grid is installed on top of the sensitive optical screen 12 19 with 2x2 mm cells for placing seeds 20 in order to fix them in one place.

The work of the stand for researching the quality of seed sowing is carried out as follows. The seed is poured into the hopper 2 of the seeding device and the latter is placed in the appropriate place above the sensitive optical screen 12 and with the grid 19, which rotates together with the rotary table 11. During the preparatory work, the computer system 13, the electric motor 15, conical drum drive 4,

From" individual engine 15, rotary disk drive 10. The speeds of the drives are selected under the condition that the speed of the unit is 2...Zm/s, the distance between the seeds in a row is 5...11cm. In addition, by changing the position of the seeder, its speed can also be controlled.

After that, the rotary table 11 is turned on from the control panel 16, which rotates, and seeds 20 periodically fall onto it, the placement of which and the distance between them is fixed by the computer system 13 (se) through the converter 14 and the sensitive optical screen 12. By changing the rotation speed of the seed drum and rotary table, we get data that is processed by the computer system and gives the results of the study. o In order to check the adequacy of the computer system, a grid 19 with sowing seeds 20 and 20 is used to measure deviations and other parameters. The grid 19 ensures stable placement of seeds 20 on the rotary table 11. The advantages of the stand include increasing labor productivity during research and expanding technological capabilities. with
