Inner spiral eye socket wheel seed manure disk

Abstract

The invention discloses an inner spiral eye socket wheel seed manure disk, which belongs to the agricultural machinery. The outer edge of the left end of the inner spiral eye socket wheel seed manuredisk is provided with an outer gear; seed filling eye sockets are evenly distributed in the circumferential direction of a middle external cylindrical surface; the right end of the inner spiral eye socket wheel seed manure disk is provided with a snap spring groove, a bearing shaft section and a manure contact cylindrical surface from left to right; inner spiral manure discharging blades are evenly distributed in the circumferential direction between the manure contact cylindrical surface and an inner cylindrical surface; a curve cone cylindrical surface and a straight line cone cylindrical surface are arranged in sequence on the inner side of the outer gear on the left end of the manure contact cylindrical surface. According to the inner spiral eye socket wheel seed manure disk, the seedfilling eye sockets on the outer cylindrical surface of the manure disk are used for realizing a seed discharging function, the manure in a manure box is conveyed to the left end of the manure disk along an axial direction through a manure discharging spiral channel formed by the inner spiral manure discharging blades, the manure contact cylindrical surface and the inner cylindrical surface by theinner spiral manure discharging blades, and slides into a manure discharging pipe through the curve cone cylindrical surface and the straight line cone cylindrical surface, and the technical integration of two functions including sowing and manure discharging is realized. Meanwhile, the disk has the advantages of novel structure and reliable quality.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an inner spiral socket wheel seeding fertilizer tray. Background technique [0002] At present, seed fertilizer should be applied at the same time of sowing, that is, fertilization operation is carried out at the same time of sowing operation. The existing technology is mainly realized by two sets of devices, that is, the fertilization operation is completed by using a fertilizer discharge device and a fertilization ditch opener before sowing, and then The sowing operation is completed by the sowing unit, and the application of the two sets of devices has caused an increase in the cost of the machine tool and a waste of resources. The outer cylindrical surface of the disc has been utilized, but its internal solid structure has not been utilized. The internal structure of the seeding disc is developed and utilized, and its design is improved, so that the nest wheel seeding disc has t...
