Abstract
The utility model discloses an adjustable type seed shaft, which is composed of a shaft, a positioning pin, a fast pulley, a movable pulley, a spring, a top plate, an adjusting screw, a sliding groove, a fast pulley seed groove and a sliding gear, etc. Not only the seed shaft plays the role of the shaft, but also the movable pulley and the fast pulley can be freely stretched under the action of the adjusting screw and the spring, the seed quantity can be adjusted, the seed shaft is simple and feasible, and adjustment can be just performed without assembly and disassembly, and fine quantity sowing can be achieved.
Description
Technical field
The utility model designs a kind of seed shaft of sower, designs a kind of adjustable easy to usely especially, fast reaches long a kind of adjustable seed shaft of life-span.
Background technology
The seed shaft that present sower is adopted all is traditional old-fashioned axle, seed wheel not flexible of hole, and seed size is restricted, and broadcast leakage appears in speed soon, and the disconnected ridge of being short of seedling seriously causes the underproduction.
Summary of the invention
In view of this in order to overcome above-mentioned shortcoming, the utility model has designed a kind of adjustable seed shaft, its objective is to address the above problem.
The utility model provides a kind of adjustable seed shaft, be installed in the seed wheel axis hole of sower, comprise being provided with accent amount screw, top board, spring, sliding tray, alignment pin, fast pulley, movable pulley, fixing composition such as crop rotation groove, the slip gear teeth in axle, the axle.
It is characterized in that: described axle is provided with alignment pin, sliding tray, accent amount screw, fast pulley be positioned pin be fixed on the axle the position on, fast pulley cooperates with movable pulley, the slip gear teeth can horizontally slip on the fast pulley seed trough, spring is arranged in the middle of fast pulley and the movable pulley, spring is under the effect of accent amount screw, accent amount screw rotates telescopic spring inwards, outwards the rotation spring expands, spring cooperates with accent amount screw makes top board, the movable pulley move left and right, need small quantities of seed, accent amount screw rotates promotion top board, movable pulley inwards, the slip gear teeth are together to fast pulley one side shifting, fast pulley seed trough gap dwindles, and institute's seeding is then few.Otherwise, accent amount screw outwards being rotated spring promote movable pulley, top board, the slip gear teeth together outwards move, and it is big that fast pulley seed trough gap becomes, and institute's seeding is then many, thereby reaches precision drilling.
Owing to adopt such scheme, adjustable seed shaft, not only the accent amount is accurate, and simple and have a practicality.
Description of drawings
Fig. 1 is a STRUCTURE DECOMPOSITION schematic diagram of the present utility model;
Fig. 2 is a cutaway view of the present utility model.
Among the figure: 1,2 alignment pins, 3 fast pulleys, 4 springs, 5 movable pulleies, 6 top boards, 7 sliding trays, 8 accent amount screws, 9 fast pulley seed troughs, the 10 slip gear teeth.
Embodiment
Referring to Fig. 2, alignment pin 2 on the described axle 1 is fixed fast pulley 3, amount of seed metering needs after a little while, accent amount screw 8 rotates inwards, promotion top board 6, movable pulley 5, spring 4 suitable sliding trays 7 one fast pulley 3 in the same way move, the gear teeth 10 that slide this moment dwindle amount of seed metering with fast pulley seed trough 9 gaps and then lack, and reach smart amount.
Amount of seed metering needs for a long time, transfers outwards rotation spring 4 promotion movable pulleies 5 of screw 8, and top board 6 outwards moves along sliding tray 7, and the slip gear teeth 10 become greatly with fast pulley seed trough gap, and amount of seed metering is then big, reaches required seeding requirement.
In sum, the utility model has promoted the use effect, the tool practicality, and group proposes utility application in accordance with the law.
Claims (2)
1. adjustable seed shaft, comprise axle, alignment pin, fast pulley, spring, movable pulley, top board, sliding tray, accent amount screw, fixedly crop rotation groove, movable pulley toothed portion, it is characterized in that, one side of axle is provided with accent amount screw, sliding tray, top board and adjusts the movable pulley move left and right, the slip gear teeth are move left and right on fixing crop rotation groove, can play the effect of regulating the amount of broadcasting.
2. adjustable seed shaft according to claim 1 is characterized in that adjustable seed shaft is provided with sliding tray, under the effect of spring and accent amount screw, makes top board promote the movable pulley move left and right in sliding tray and finishes required amount of seed metering.
