Abstract
The utility model relates to an aspirated-air type precision sowing mechanism, comprising a seed chamber and a seed receiving tube. A negative pressure air aspirating cavity is arranged on the seed chamber. A seed aspirating disc is arranged at one side of the air aspirating cavity. A seed taking chamber is arranged on the periphery outside the seed aspirating disc. Seed aspirating holes are arranged on the seed taking chamber. Seed passing holes are also arranged on the inner circle of the seed aspirating disc. The utility model can be matched with the seeders with various types. The utility model better solves the problem of the seed discharging in precision bunch planting. When the seeds are broadcast into a hole, the seeds can not be squeezed into a stack. Simultaneously, the aspirated-air type precision sowing mechanism can realize precision equidistant drill seeding. Hole spaces can be adjusted by adjusting the rotation speed of the seed aspirating disc. Seeding quantity can be adjusted by adjusting the position of a seed scraping plate. The seeding accuracy of the aspirated-air type precision sowing mechanism can be controlled at grains.
Description
The utility model relates to a kind of sower feed mechanism, especially a kind of driven sucking precise amount feed mechanism.
Present sower has drilling and bunch planting, and drilling consumption kind of amount is big, and in the crop management afterwards, especially operations labor intensity such as final singling, thinning is big, thereby in recent years along with the raising of seed quality, uses increasing gradually of bunch planting method.But present grouping mechanism such as duck-beak type grouping mechanism, its duckbilled are easily stopped up by earth and cause broadcast leakage, never have fine solution in the control of amount of seed metering, and seed is too much and be extruded into a pile, thereby makes the popularization of this method be subjected to influence.
The purpose of this utility model provides a kind of sower feed mechanism that can control amount of seed metering more exactly and can not stop up, especially a kind of driven sucking precise amount feed mechanism.
The utility model comprises seed chamber, inoculated tube, on seed chamber, be provided with negative pressure aspiration chamber, described aspiration chamber is on seed chamber top and be a semicircular arc, this aspiration chamber one end leads to negative-pressure air fan, and other end side is provided with seeds sucker, and described seeds sucker is fixed on one, the aspiration chamber outside of dish be provided with outwardly open kind of the chamber of getting a week, getting has several suction holes on kind of the chamber, suction hole with the aspiration chamber with get kind of a chamber and be communicated with, also be provided with several on the circle in the seeds sucker and cross kind of a hole.
Understand the situation of sowing for knowing at seeding time, get kind of a place, chamber at the feed mechanism shell and be provided with observation window, this observation window seals with transparent material.
For better controlling the amount of sowing, be provided with adjustable seeds scraper on seeds sucker top.
The utility model can with the supporting use of various sower, better realized the seeding problem of precise hole sowing, after broadcasting, seed can not be extruded into a pile, can realize also simultaneously that smart amount is even apart from drilling, regulate the rotating speed of seeds sucker and just can adjust the cave distance, regulate the position of seeds scraper and just can adjust the amount of sowing, its seeding accuracy can be controlled to grain.
Below in conjunction with accompanying drawing the utility model is described.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Fig. 3 is one of the utility model and the schematic diagram of the supporting use embodiment of sower.
With reference to accompanying drawing, the utility model comprises seed chamber (5), inoculated tube (8), on seed chamber, be provided with negative pressure aspiration chamber (3), the aspiration chamber is on seed chamber top and be a semicircular arc, aspiration chamber one end leads to negative-pressure air fan, other end side is provided with seeds sucker (10), described seeds sucker is fixed on one (9), the aspiration chamber outside of dish be provided with outside opening (2) week get kind of a chamber (6), get several suction holes are arranged on kind of the chamber, suction hole with aspiration chamber (3) with get kind of a chamber (5) and be communicated with, get kind of a chamber for seed can in time be entered from seed chamber (5), also be provided with several on the circle in the seeds sucker and cross kind of a hole (11), understand the situation of sowing for knowing at seeding time, get kind of a place, chamber at feed mechanism shell (4) and be provided with observation window (2), this observation window seals with transparent material.For better controlling the amount of sowing, be provided with adjustable seeds scraper (7) on seeds sucker top.
The utility model course of work is as follows: seed enters seed chamber and some from the pipe of sowing and enters and get kind of a chamber from crossing kind of a hole, in the aspiration chamber, produce negative pressure by negative pressure straw (1) by negative-pressure air fan, when kind of the chamber of getting of seeds sucker forwards negative pressure aspiration chamber when place to, entering the seed of getting kind of chamber has several quilts to inhale on suction hole, the seed that the seeds sucker rotation will be inhaled on suction hole is taken away, forward when top to when getting kind of a chamber, seeds scraper scrapes unnecessary seed, regulate the position of seeds scraper, with regard to the controlled amount of sowing, produce negative pressure aspiration chamber when getting kind of a chamber, seed on the suction hole promptly falls into gets kind of a chamber, get kind of a chamber and forward seeding unit when below to, seed is promptly discharged from the opening of getting kind of chamber.
Embodiment
Fig. 3 is one of the utility model and the use schematic diagram of the supporting use embodiment of sower, and the inoculated tube of feed mechanism (8) is connected with the seed-box of sower, and negative pressure straw (1) connects air-introduced machine.
Claims (3)
1, a kind of driven sucking precise amount feed mechanism, comprise seed chamber, inoculated tube, on seed chamber, be provided with negative pressure aspiration chamber, described aspiration chamber is on seed chamber top and be a semicircular arc, this aspiration chamber one end leads to negative-pressure air fan, other end side is provided with seeds sucker, described seeds sucker is fixed on one, the aspiration dish is by outwardly open kind of the chamber of getting that is provided with in a week in the outside, aspiration chamber, get several suction holes are arranged on kind of the chamber, suction hole with the aspiration chamber with get kind of a chamber and be communicated with, also be provided with several on the circle in the seeds sucker and cross kind of a hole.
2, driven sucking precise amount feed mechanism as claimed in claim 1 is characterized in that being provided with adjustable seeds scraper on seeds sucker top.
3, driven sucking precise amount feed mechanism as claimed in claim 1 or 2 is characterized in that getting kind of a place, chamber at the feed mechanism shell is provided with observation window, and this observation window seals with transparent material.
