Description

Automatically controlled strength matching used with feed mechanism for seed blows She Shidaozhong mechanisms

Technical field

The invention belongs to agricultural machinery, relates generally to a kind of mechanical seeding assembly.

Background technology

The mechanical feed mechanism for seed of existing various structures is adopted in the sowing course of conveying in seed after being discharged in feed mechanism for seed Complete to be sown into the conveying before kind of bed soil earth with the freely falling body mode conducted oneself with dignity by seed, due to seed and seed spout inner tubal wall Irregular and uncontrollable multiple impacts, change seed from feed mechanism for seed discharge when running orbit, direction, speed, significantly Degree reduces the operation quality of sowing.

The content of the invention

The problem that the purpose of the invention exists aiming at above-mentioned prior art, R ＆ D design one kind is matched somebody with somebody with feed mechanism for seed The automatically controlled strength that uses of set blows She Shidaozhong mechanisms, blows the mode of penetrating by pressed gas and adjusts control seed and enters in grain conductor Running orbit, direction, the speed before bed soil earth are planted, prior art is overcome and solve the problems, such as, guarantee seeding operation is reached Quality, service-strong purpose.

What the purpose of the invention was realized in：Automatically controlled strength matching used with feed mechanism for seed blows She Shidaozhong mechanisms The seed spout connected including seeding-apparatus assembly and with the seeding-apparatus assembly, what is be interconnected on the seed spout bottom matches somebody with somebody Dress air flow blowing and jetting grain conductor, defeated kind of sensor is fitted on seed spout；Cylinder block is fixedly mounted with support body, rack-and-pinion piston can be axial It is mobile installed in cylinder block fluid chamber, position is matched somebody with somebody in the cylinder block body cavity, between rack-and-pinion piston and support body Dress compression spring, the both ends of the surface of the compression spring are engaged with rack-and-pinion piston and support body respectively, external in the cylinder It is parallel to each other at side and rotatably configures I axle and II axle, electric notor and driving gear is packed on I axle, driven gear It is packed on II axle with sector gear, the driving gear is engaged with driven gear, the sector gear is in rack-and-pinion piston Engage or be disengaged to coordinate, open up air admission hole and steam vent respectively on the end cap of cylinder block, exhaust check valve is fitted in end Cover, and with steam vent in cooperation is turned off or on, the air inlet end of air flow blowing and jetting grain conductor is connected with end cap seal, and will row Stomata contains, and screen pack is fitted in air flow blowing and jetting grain conductor tube chamber, and air is equipped with by breather check valve on the end cap Cleaner, it is in connect or close cooperation that the air filter passes through breather check valve and air admission hole；Wire is by automatic controller Connected with defeated kind of sensor and electric notor respectively.

The invention novel in structural design, rationally, seeding operation efficiency and spacing in the rows qualification rate are high, and seeding quality is good, makes With reliability, failure is few, high degree of automation.Mechanism can also realize and meet that zero-speed seeding operation uses needs, be applicable model Enclose wide.

Specific embodiment

The invention embodiment is described in detail below in conjunction with the accompanying drawings.A kind of and matching used electricity of feed mechanism for seed Control strength blows She Shidaozhong mechanisms includes seeding-apparatus assembly 1 and the seed spout 3 connected with the seeding-apparatus assembly 1, described defeated The equipped air flow blowing and jetting grain conductor 4 being interconnected on the bottom of pipe 3 is planted, defeated kind of sensor 2 is fitted on seed spout 3；In support body Be fixedly mounted with cylinder block 18 on 16, rack-and-pinion piston 19 be axially movable installed in the fluid chamber of cylinder block 18, in the cylinder block 18 The equipped compression spring 17 in position, the two ends of the compression spring 17 in body cavity, between rack-and-pinion piston 19 and support body 16 Face is engaged with rack-and-pinion piston 19 and support body 16 respectively, is parallel to each other at the outside left of the cylinder block 18 and rotatably The axle 11 of configuration I and II axle 13, electric notor 10 and driving gear 12 be packed on I axle 11, driven gear 14 and sector gear 15 It is packed on II axle 13, the driving gear 12 is engaged with driven gear 14, the sector gear 15 is in rack-and-pinion piston 19 Engage or be disengaged to coordinate, open up air admission hole 8 and steam vent 21, exhaust check valve 20 respectively on the end cap 9 of cylinder block 18 It is fitted on end cap 9, and with steam vent 21 in cooperation is turned off or on, the air inlet end of air flow blowing and jetting grain conductor 4 is close with end cap 9 Envelope connection, and steam vent 21 is contained, screen pack 22 is fitted in the tube chamber of air flow blowing and jetting grain conductor 4, is passed through on the end cap 9 Breather check valve 7 is equipped with air filter 6, and the air filter 6 is in connect or close by breather check valve 7 and air admission hole 8 Close cooperation；Wire connects automatic controller 5 with defeated kind of sensor 2 and electric notor 10 respectively.

During operation, when seeding-apparatus assembly 1 is by seed feeding seed spout 3 by defeated kind of sensor 2, defeated kind of sensor 2 Electric signal is delivered into automatic controller 5, the electric notor 10 for rotating immediately passes sequentially through I axle 11, driving gear 12, driven gear 14th, II axle 13 drives sector gear 15 to rotate, and enters same in air flow blowing and jetting grain conductor 4 from lower port in the seed of seed spout 3 When, the teeth of sector gear 15 depart from and are engaged with the tooth bar of rack-and-pinion piston 19, in the case where compression spring 17 is acted on, rack-and-pinion piston 19 is quick to movement at end cap 9, and the gas in cylinder block 18 opens exhaust check valve 20 after being compressed, and pressed gas are through steam vent 21 are blown into seed on kind of bed soil earth in air flow blowing and jetting grain conductor 4；Thereafter, the teeth and tooth bar of the sector gear 15 of rotation The tooth bar of formula piston 19 enters engagement, drives rack-and-pinion piston 19 to be transported to the side of compression pressure spring 17 in cylinder block 18 Dynamic, now steam vent 21 is closed, and breather check valve 7 is opened, and air filter 6 is connected with air admission hole 8, the air warp in air Negative pressure is drawn into cylinder block 18 after filtering, is to blow kind of a deposit gas next time, is circulated successively.Screen pack 22 avoids air flow blowing and jetting Impurity in grain conductor 4 blocks steam vent 21.
