Description
Technical field
The invention belongs to agricultural machinery, relate generally to a kind of dry land potted-seedling transplanting pulsation variable precision cave water injecting mechanism.
Background technology
At present, China's field-transplanting mainly uses furrow irrigation, and this irrigation method irrigation quantity is big, and water use efficiency is low, causes the waste of water resource.In order to save farmland irrigation water, a kind of rotary water filling device of exocoel is researched and developed successfully, is mainly used in pouring during planting seed.During operation, this mechanism's inner chamber maintains static, and exocoel rotates, when exocoel rotates to outlet below inner chamber, and the water injection pipe alignment cave water filling on exocoel, when exocoel turns over outlet below inner chamber, stop water filling.Pouring effect can improve in this mechanism, and reduces water consumption, it is achieved Precision Irrigation.But there is problems of, this mechanism can only realize pinpointing water filling, it is impossible to ensures when exocoel rotates, two water injection pipes are had to be directed at former and later two cavities water fillings all the time, and owing to can not control pressure or the flow of water outlet saliva, during water filling, cavities both sides easily cave in, and it cannot be guaranteed that the water yield of cavities pouring.
Summary of the invention
The purpose of the invention is aiming at the problem that above-mentioned prior art exists, actual demand in conjunction with Semen Maydis potted-seedling transplanting machinery equalization, design provides the pulsation variable precision cave water injecting mechanism of a kind of new construction, reaches that ripple control water filling, water filling be accurate and the reliable purpose of operation.
The object of the present invention is achieved like this: a kind of pulsation variable precision cave water injecting mechanism, land wheel passes sequentially through driving shaft, first drive sprocket, first driving chain, first driven sprocket, first power transmission shaft is connected with cave water filling wheel assembly, water tank is connected by water-supply-pipe with cave water filling wheel assembly, it is characterized in that: on the first described power transmission shaft, be fixedly mounted with the second drive sprocket, second driving shaft is fixedly mounted with cam and the second driven sprocket, second driving chain set fits on the second drive sprocket and the second driven sprocket, the gear ratio of described second drive sprocket and the second driven sprocket is 1:N, described N is the radical of water injection pipe on cave water filling wheel assembly, water-supply-pipe is equipped with water pump and pressure-control valve or choke valve successively, elastic telescopic controls bar two ends and contacts cooperation with cam and pressure-control valve or choke valve respectively；The inner tube A lower side wall portion of described cave water filling wheel assembly is offered variable cross-section notch, the fan angle α >=360 °/N of described variable cross-section notch.
The present invention controls pressure valve or choke valve by cam, and use variable cross-section notch arrangement, achieve pulsed infusion, i.e. during the water injection pipe laterally water filling in cave on cave water filling wheel assembly, outlet pressure and the water yield are little, it is ensured that cavities complete, when water injection pipe aligned beneath cavities bottom water injection, outlet pressure is big, water yield foot, it is ensured that the effect of cave water filling, have novel and reasonable structure, water filling precisely, water filling quality is good, service-strong feature.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present invention is described in detail.nullA kind of pulsation variable precision cave water injecting mechanism，Land wheel 8 passes sequentially through driving shaft 9、First drive sprocket 11、First driving chain 10、First driven sprocket 12、First power transmission shaft 13 is connected with cave water filling wheel assembly 16，Water tank 1 is connected by water-supply-pipe 3 with cave water filling wheel assembly 16，It is characterized in that: on the first described power transmission shaft 13, be fixedly mounted with the second drive sprocket 14，Second driving shaft 6 is fixedly mounted with cam 7 and the second driven sprocket 17，Second driving chain 15 set fits on the second drive sprocket 14 and the second driven sprocket 17，The gear ratio of described second drive sprocket 14 and the second driven sprocket 17 is 1:N，Described N is the radical of water injection pipe 16-1 on cave water filling wheel assembly 16，Water-supply-pipe 3 is equipped with water pump 2 and pressure-control valve or choke valve 4 successively，Elastic telescopic controls bar 5 two ends and contacts cooperation with cam 7 and pressure-control valve or choke valve 4 respectively；The inner tube 16-2 A lower side wall portion of described cave water filling wheel assembly 16 is offered variable cross-section notch 16-3, the fan angle α >=360 °/N of described variable cross-section notch 16-3.
nullWhen water injection work uses，The rotary motion of land wheel 8 is successively through driving shaft 9、First drive sprocket 11、First driving chain 10、First driven sprocket 12、First power transmission shaft 13 drives the cave water filling wheel assembly 16 with N number of water injection pipe 16-1 to rotate，Simultaneously，It is packed on the first power transmission shaft 13 the second drive sprocket 14 rotated through the second driving chain 15、Second driven sprocket 17、Second driving shaft 6 drives cam 7 to rotate，Clear water in water tank 1 is sent into cave water filling wheel assembly 16 intracavity through pressure-control valve or choke valve 4 by water pump 2，When a water injection pipe 16-1 turns to variable cross-section notch 16-3 cooperation position，Cam 7 controls bar 5 by elastic telescopic makes pressure-control valve or choke valve 4 change and control the pressure of water filling，Water injection rate is controlled ascending under variable cross-section notch 16-3 coordinates、The least，Realize pulsed infusion operation，Avoid water that damage and the water filling of cave sidewall are lost，Ensure water injection work effect.When having N root water injection pipe 16-1, cave water filling wheel assembly 16 rotates a circle, and cam 7 synchronous axial system N encloses, and the gear ratio of the i.e. second drive sprocket 14 and the second driven sprocket 17 is 1:N.
