Embodiment Construction

[0054] The present invention is further described below in conjunction with embodiment.

[0055] Such as figure 1 As shown, the corn finger-clamp type seed metering device seeding quality inspection platform of the present invention includes a seed metering device bracket 1 for fixing the finger-clip type seed metering device 2 and a seed tube bracket 13 for fixing the seed tube 14 , Slidable coupling 3, speed reducer 5, motor support 6, motor 7, Hall sensor 12, photoelectric sensor 15, seed block 16 and control system.

[0056] The finger clip type seed meter 2 is fixed on the seed meter bracket 1 through three-point support, and the fixing method is a suspension support type, which facilitates the installation and disassembly of the finger clip type seed meter 2 .

[0057] The seed blocking plate 16 is arranged on the upper part of the finger-clip seed metering device 2 and is connected with the seed inlet of the finger-clip seed metering device 2 . Seed guide tube 14 is c...

Abstract

The invention belongs to the technical field of agricultural machinery and in particular relates to a seed sowing quality test bed and a seed sowing quality test method for a corn finger-clip-type seed sowing device. The test bed comprises a seed sowing device support (1) used for fixing a finger-clip-type seed sowing device (2), a seed guiding pipe support (13) used for fixing a seed guiding pipe (14), a slidable coupler (3), a speed reducer (5), a motor stand (6), a motor (7), a Hall sensor (12), a photoelectric sensor (15), a seed blocking plate (16) and a control system, wherein the seed guiding pipe (14) is connected below a seed falling hole of the finger-clip-type seed sowing device (2), the photoelectric sensor (15) is arranged on the seed guiding pipe (14), and the seed guiding pipe (14) sends out a pulse signal for each seed passing through. The test bed provided by the invention is small in size, easy to operate, low in manufacturing cost and strong in practicability, can test seed sowing indexes of the seed sowing device such as qualified index, reseeding index and miss seeding and can monitor reseeding and miss seeding conditions of each finger clip of the finger-clip-type seed sowing device in real time.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a seeding quality detection platform and a seeding quality detection method of a corn finger-clamp type seed metering device. Background technique [0002] Today, with the rapid development of agricultural mechanization, corn seed metering devices are widely used, which doubles the efficiency of agricultural production. The quality of the corn seed meter determines the quality of the sowing. Sowing uniformity is a very important factor affecting crop yield, and reasonable and uniform plant spacing can achieve high yield. If the distance between two seeds is too close, the growth of crops after emergence will be affected; if the distance between two seeds is too far, land resources will be wasted; in both cases, yield loss will result. The seed meter on the seeder is a device that discharges the seeds into the sowing row individually, and it is a key c...
