Detailed description of the invention
Below, by exemplary embodiment, this utility model is specifically described.It should be appreciated, however, that in the case of not being further discussed below, element, structure and features in an embodiment can also be advantageously incorporated in other embodiments.
In description of the present utility model, it should be noted that, " interior ", " outward " of feed mechanism for seed, " on ", D score, the orientation of the instruction such as "front", "rear" " top " " bottom " or position relationship be based on the position relationship shown in accompanying drawing 1, it is for only for ease of description this utility model and simplifies description, rather than instruction or the device of hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
nullSee Fig. 1、Fig. 2、Fig. 4 and Fig. 7，As shown in the figure，Feed mechanism for seed of the present utility model，Sowing for a ridge duplicate rows，Including housing 1，Housing 1 is internally provided with rotating discharge plate 2，Internal for housing 1 longitudinal subdivision is formed induction chamber and seed chamber by discharge plate 2，The top of housing 1 is provided with seed inlet，The bottom of housing 1 is provided with sowing port，The bottom of sowing port is provided with point kind of a unit 3，Kind of a unit 3 is divided to include sowing port just divides kind of a box 31，The upper bottom surface dividing kind of box 31 is opening and arranges，Kind of box 31 inside is divided to cross fixing axle 33，Point kind of box 31 is internal is divided into two chambers in left and right in the middle part of point kind of box on the basis of longitudinal surface，The axle sleeve 34 that can rotate it is arranged with around fixing axle 33 on fixing axle 33，The baffle plate 37 that can block arbitrary chamber upper end open it is installed with on axle sleeve 34，Reversal means 36 also it is installed with on axle sleeve 34，Reversal means 36 can be against the lateral surface of discharge plate，Reversal means 36 promotes baffle plate 37 to rotate under the drive of discharge plate 2，When baffle plate 37 turns to the chamber sheltering from one of them，Seed falls into another chamber，So can be achieved with the separation of duplicate rows seed，Make sowing more accurate.
See Fig. 3-Fig. 6.As shown in figures 3 to 6, discharge plate 2 includes the multiple dish teeth 21 being distributed on discharge plate 2 excircle, and the discharge plate 2 between adjacent disc tooth is provided with the feed outlet 22 of two adsorbable seeds；Baffle plate 37 is provided with opening with the junction of axle sleeve 34, torsion spring 35 it is provided with on axle sleeve 34, torsion spring 35 is located on axle sleeve 34 through opening sleeve, between reversal means 36 and baffle plate 37 at an acute angle, the angle Selection of this acute angle depends on the length of reversal means, and the when of acute angle, the length of reversal means can meet drive flapper at the upper end open of chamber without long, and when acute angle, the dynamics of the fluctuation dish tooth that reversal means is born is optimum, the most preferably 30o-60o, effect the most at an acute angle is, when reversal means is against on dish tooth, baffle plate can move at left side or right lateral position, and when baffle plate continues to move to, baffle plate disengaging dish tooth, because there is certain distance between dish tooth and the upper end open of chamber of discharge plate bottommost, the variation of displacement can be realized by reversal means；Under non-driving state, the end of reversal means 36 is against on the dish tooth 21 turning to bottommost discharge plate, and baffle plate is now in right lateral position or left lateral position, in the present embodiment, being at left chamber with baffle plate, one end of torsion spring 35 is against in reversal means 36, and the other end is against on point kind of box 31 inwall.
See Fig. 5, for the side view of in Fig. 1 point of kind of unit.As it is shown in figure 5, feed mechanism for seed also includes being arranged on the seeding unit 4 bottom point kind of unit 3, seeding unit 4 includes the seeding 41 corresponding to left and right cavity bottom, and is integrally connected to the discharging tube 42 bottom seeding 41.Seeding 41 is set to easily guide the hollow cone of seeds fall；Two discharging tubes 42 shift to install, so by the distance between regulation discharging tube, the i.e. interval of two row seeds on scalable ridge.
By above structure, feed mechanism for seed is when seeding, seed from seed inlet by enter enclosure interior seed chamber, induction chamber air-breathing, make to be formed between induction chamber and seed chamber pressure reduction, seed is adsorbed on the feed outlet of discharge plate under differential pressure action from seed chamber, and at discharge plate operating to bottom sowing port, the reversal means in kind of unit is divided to be against on the dish tooth of discharge plate, discharge plate rotates and promotes reversal means motion, baffle plate moves simultaneously, torsion spring is compressed, when baffle plate moves to right chamber top, when sheltering from right chamber, seeding unit is in opening state, seed falls into seeding unit discharge from left chamber；Along with discharge plate is rotated further, dish tooth departs from reversal means, and under the effect of torsion spring, baffle plate is returned to left chamber top, shelters from left chamber, and seed falls into seeding unit discharge from right chamber；Alternate cycles realizes double row sowing.
It addition, the bottom of discharge plate 2 be provided with seed can be scraped from feed outlet scrape kind of tongue 5, go under discharge plate at sowing port, under the effect scraping kind of tongue, seed can be scraped.
In this utility model, as in figure 2 it is shown, the side of discharge plate 2 is provided with the sprocket wheel 6 that discharge plate 2 can be driven to rotate.
In order to point kind of a unit is connected on housing, the outside dividing kind of box 31 is symmetrically arranged with the connector 32 being connected with housing 1, and connector 32 is bolted plants on box, so at housing with dividing, when need not point kind of unit, can will point kind of unit disassembling or a replacing by demounting bolt.
It addition, this utility model additionally provides a kind of seeder, the bottom of this seeder is provided with above-mentioned feed mechanism for seed.
By feed mechanism for seed of the present utility model and seeder, seed is at point kind of the unit through feed mechanism for seed, and when seed demand sows skidding upper left to ridge, baffle plate moves to right lateral position and blocks right chamber mouth, thus during sowing seed, can realize Precise sowing.
The above; it it is only preferred embodiment of the present utility model; it it is not the restriction that this utility model is made other form; any those skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified as the Equivalent embodiments of equivalent variations is applied to other field; but it is every without departing from technical solutions of the utility model content; any simple modification, equivalent variations and the remodeling made above example according to technical spirit of the present utility model, still falls within the protection domain of technical solutions of the utility model.
