Description
Technical field
The utility model relates to the draining crop mechanism of a kind of grain, oil crops and seed drying equipment thereof, especially the pulse pneumatic draining crop mechanism of rower drier.
Background technology
Draining crop mechanism is the rotatable parts of drying tower control grain flow, is the important component part of grain drier.Draining crop mechanism generally is made up of a minute grain awl, row's grain parts, transmission device and frame etc.Common draining crop mechanism mainly contains four kinds of forms at present: swing type draining crop mechanism, reciprocating type draining crop mechanism, oscillatory type draining crop mechanism and vane type draining crop mechanism.
Row's grain parts of swing type draining crop mechanism are oscillating decks that is positioned at branch grain awl below, under toggle drives, oscillating deck is made rotary oscillation around central shaft in certain limit, has changed oscillating deck and the gap of dividing grain awl below row's grain mouth thus, reaches the purpose of row's grain; This mechanism structure is simple, and relatively be fit to bulky grain and contain assorted higher material, but its installation requirement precision height, inconvenience, the material bad adaptability different to particle diameter are adjusted in the gap.Row's grain parts of reciprocating type draining crop mechanism are screens that is positioned at the reciprocal horizontal movement of branch grain awl below, by the stocking angle of side-to-side movement change grain, and the row's of realization grain; This mechanism is good to the adaptability of different material, but under the percentage of impurity condition with higher, stops up easily.The oscillatory type draining crop mechanism is driven by vibrating motor, makes the straight-line oscillation of delivery plate horizontal direction, and the row's of realization grain is simultaneously by adjusting adjusting screw(rod) adjustment row grain gap under the grain guard board; Its shortcoming is a complex structure, and spring and drive disk assembly are prone to fault, and row's grain gap is difficult for adjusting.Vane type draining crop mechanism (CN2695414Y) is at row's grain mouth plurality of impeller to be set, and the material in the groove can be forced to discharge during wheel rotation; Apparatus structure and transmission are complicated, and impurity easily is wrapped in and results in blockage on the impeller and produce phenomenon such as broken grain, is not easy to guarantee the quality of dry back grain or oil plant.
Summary of the invention
For solve the existing ubiquitous adaptability problem of draining crop mechanism to different material, row's grain is not smooth under the higher situation of percentage of impurity, influence deficiencies such as drying quality and complex structure, row's grain gap adjustment are difficult for, the utility model provides a kind of draining crop mechanism with impulse action of compact conformation.This mechanism not only is easy to the row's of adjustment grain speed, and accurately flow vector is arranged in control, and can not stop up because of percentage of impurity is higher, need not the row of adjustment grain gap, can guarantee out the quality of machine material effectively.
The technical solution of the utility model is:
Delivery plate is fixed on the traction framework, and the piston rod of the cylinder on drawing framework and being fixed on support is connected, and by the traction of piston rod, makes the traction framework produce impulse movement, realizes opening and closing two states.When the traction framework is in out, divide grain awl feed opening all to be opened, material is discharged.When the traction framework is in off-position, divide grain awl feed opening to be closed, stop discharge.Limit Bearing and block bearing guarantee that the traction framework produces horizontal slip, and location bearing guarantees that the swing of both sides does not take place the traction framework.
The movement velocity that air inlet frequency by adjusting cylinder or folding time guarantee to draw framework, thereby Flow of Goods and Materials speed, drying time and water evaporation quantity in the control drying machine.
The beneficial effects of the utility model are: the utility model compact conformation, and operate steadily, manufacture easily, can adapt to the demand of various grain driers.Need not to adjust row's grain gap, can not contain assorted more the obstruction because of grain and oil plant, row's grain is stable, even, and the row's of control flow vector accurately, improves the moisture uniformity that the machine material effectively.
Description of drawings
Below, will the utility model and improvement thereof be described in more detail with reference to the partial schematic diagrammatic sketch of an embodiment.

Fig. 2 is that the master of draining crop mechanism embodiment looks complete section surface construction figure, and draining crop mechanism is in the duty (draining crop mechanism stop position) of full cut-off.
Fig. 3 is the I--I cutaway view of Fig. 2.
Fig. 4 is that the master of draining crop mechanism embodiment looks complete section surface construction figure, and draining crop mechanism is in the duty of opening.
Among the figure, 1. traction framework, 2. Limit Bearing, 3. delivery plate, 4. block bearing, 5. connector, 6. piston rod, 7. cylinder, 8. cylinder support, 9. baffle, 10. minute grain awl, 11. cylinder guide rails, 12. location bearings.
The specific embodiment
From Fig. 1 and Fig. 3 as can be seen, draining crop mechanism is made up of delivery plate (3), traction framework (10), connector (5), piston rod (6) and cylinder (7) etc.Delivery plate (3) is fixed on the traction framework (1), is connected with the piston rod (6) of cylinder (7) by connector (5).Cylinder (7) is fixed on the cylinder support (8), and by the traction of piston rod (6), traction framework (1) produces impulse movement, drives feed opening and opens and close, and realizes the batch (-type) discharge.
As can be seen from Figure 2, delivery plate (3) be contained in branch grain awl (10) below.When draining crop mechanism was shut down, the center of delivery plate (3) should be consistent with minute center of grain awl (10) discharging opening.Simultaneously, the width of delivery plate (3) is slightly larger than branch grain awl feed opening, to guarantee that delivery plate (3) can the row's of sealing grain mouth when shutting down (when draining crop mechanism is in closed condition).
As can be seen from Figure 3, Limit Bearing (2) and block bearing (4) guarantee that traction framework (1) produces horizontal slip, and location bearing (12) guarantees that the swing of both sides does not take place traction framework (1).Delivery plate (3) is made the rectilinear motion of horizontal direction under the drive of traction framework, guarantee that material evenly falls in the drying machine.By adjusting the upper-lower position of block bearing (4); make Limit Bearing (2) contact-making surface be close to cylinder guide rail (11); definite traction framework (1) is gone up the gap between delivery plate (3) and the branch grain awl feed opening; thereby guarantee that (when draining crop mechanism is in closed condition) material can't flow out just under stopped status, and need not the row of adjustment grain gap in the drying course.
As can be seen from Figure 4, compressed air enters cylinder (7) is subjected to displacement piston rod (6), promotes traction framework (1) horizontal movement has taken place, and divides grain awl feed opening to be opened, and material is discharged.Baffle (9) protection piston rod (6) and other connectors the do not fallen impact and the wearing and tearing of material.Air inlet frequency or folding time by adjustment cylinder (7) guarantee to draw the horizontal movement speed of framework (1), thereby control Flow of Goods and Materials speed, drying time and water evaporation quantity in the drying machine effectively.
