Description
Technical Field
The invention belongs to agricultural machinery, and mainly relates to a mechanical hole sowing and seed discharging mechanism.
Background
The hole sowing agricultural technique is a new agricultural technique with the characteristics of high sowing precision, small soil disturbance, low energy consumption and the like. In order to meet and adapt to popularization and application of the agricultural technical method, hole sowing mechanisms of various structural types are researched and developed in recent years, but due to the structural design defects, the technical problems of low operation efficiency, poor hole forming quality, multiple operation faults, complex structure, high manufacturing cost and the like generally exist, and large-area popularization and application of the hole sowing agricultural technical method are restricted.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and the touch type hole pricking and seeding mechanism is researched and designed by combining the actual needs of the current agricultural production operation, so that the aims of simple structure, low manufacturing cost, reliable use and high operation efficiency are achieved.
The purpose of the invention is realized as follows: the touch type hole pricking seeding mechanism comprises a shell with a seed cavity, a hole pricking piston is arranged on the shell in an inserting and assembling mode, the hole pricking piston can move up and down and is positioned at the position outside the seed cavity, a pressure regulating screw plate is arranged on the shell and is coaxially arranged with the hole pricking piston at the position above the hole pricking piston, a pressure regulating knob is arranged on the outer portion of the upper end of the pressure regulating screw plate, a pressure spring is arranged on the shell and is positioned between the pressure regulating screw plate and the hole pricking piston, N hole depth positioning regulating holes are vertically arranged on the hole pricking piston, the hole pricking piston is in closed fit or open fit with a port below the seed cavity, a touch supporting plate provided with the hole depth regulating screw can move up and down and is arranged on the outer portion of the lower side of the hole pricking piston, and the hole seeding regulating screw is in inserting fit or separated from the inserting fit with the N hole depth positioning regulating holes in sequence.
The invention has the advantages of simple structure, low cost, high efficiency of hole sowing operation, few operation faults, simple and convenient adjustment operation, strong applicability, capability of meeting the requirements of different sowing depth operations of various crops and providing technical support for large-area popularization and application of hole sowing agricultural technology.

1. the device comprises a pressure adjusting knob, 2, a pressure adjusting screw plate, 3, a pressure spring, 4, a hole pricking piston, 5, a hole depth positioning adjusting hole, 6, a shell, 7, a hole depth adjusting screw, 8, a touch supporting plate, 9 and a seed cavity chamber.
Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. A touch hole pricking seeding mechanism comprises a shell 6 with a seed chamber 9, a hole pricking piston 4 which can move up and down is arranged on the shell 6 and is positioned at the outer side of the seed chamber 9 in an inserting and matching way, a pressure regulating screw plate 2 is arranged on the shell 6 and positioned above the hole pricking piston 4 and coaxial with the hole pricking piston 4, a pressure regulating knob 1 is arranged on the outer part of the upper end of the pressure regulating screw plate 2, a pressure spring 3 is arranged on the shell 6 and between the pressure regulating screw plate 2 and the hole pricking piston 4, n hole depth positioning adjusting holes 5 are vertically arranged on the hole pricking piston 4, the hole pricking piston 4 is in closed fit or open fit with a seed discharging port below a seed cavity 9, a touch supporting plate 8 provided with a hole depth adjusting screw 7 is arranged on the outer part of the lower side of the hole pricking piston 4 in a vertically adjustable manner, the hole depth adjusting screws 7 are in insertion fit or separation fit with the N hole depth positioning adjusting holes 5 in sequence.
When the hole pricking piston 4 is used in an operation, the shell 6 drives the hole pricking piston 4 to integrally move downwards, the hole pricking piston 4 is firstly inserted into a soil layer to form a hole, the shell 6 continues to move downwards after the touch supporting plate 8 is contacted with the surface of the soil layer, at the moment, under the pushing of the soil reaction force, the touch supporting plate 8 is matched with the hole depth positioning adjusting hole 5 through the hole depth adjusting screw 7 to drive the hole pricking piston 4 to move upwards in the shell 6, the lower side part of the hole pricking piston 4 is separated from the closed matching with the seed discharging opening below the seed chamber 9, seeds in the seed chamber 9 are sowed into the hole pricked by the hole pricking piston 4 from the opened seed discharging opening, and hole sowing operation is completed. When the shell 6 drives the hole pricking piston 4 to move upwards integrally, the hole pricking piston 4 moves downwards in the shell 6 under the action of the pressure spring 3, and the hole pricking piston 4 closes the seed discharging port below the seed cavity 9 again to circulate in sequence. The pre-pressure of the pressure spring 3 is adjusted by rotating the pressure adjusting knob 1 and utilizing the pressure adjusting screw plate 2, so that the hole-punching operation requirements under different specific resistance soil conditions are met. The hole depth positioning and adjusting hole 5 can meet the requirements of sowing depth adjustment of different crops, and the application range is expanded.
