Some improvement to Manpower automatic rice transplanter

Technical field the invention belongs to the agricultural tool field.

The multifunctional combined operation of technical background is transplanted seedlings, sower has carried out some improvement to Manpower automatic rice transplanter, but Manpower automatic rice transplanter still exists carrying inconvenient, disadvantages such as vertical seedlings sending mechanism is complicated, and conveyer belt need be done in other factory, and square nut is loosening easily.

Summary of the invention the present invention is the running gear to Manpower automatic rice transplanter, vertical seedlings sending mechanism, and square nut, the seedling case, frames etc. are carried out some improvement.

Manpower automatic rice transplanter is transported to farm work, very inconvenient by people's carrying, the method for solution, the one, travel with crawler belt; The 2nd, four iron tyres are installed.The method that iron tyre is installed is, with the front-wheel axle bed is that the land wheel axle bed is installed in seedling ship leftover bits and pieces iron front, on the axle bed front axle being installed is land axle, in seedling ship leftover bits and pieces iron back the trailing wheel axle bed being installed is the regulating wheel axle bed, on the trailing wheel axle bed hind axle being installed is tension wheel shaft, two iron tyres and a sprocket wheel are installed on the front axle, two iron tyres and a sprocket wheel are installed on hind axle, the front and back sprocket wheel links up with chain.So both solve the carrying problem of Manpower automatic rice transplanter, also increased the power and the shallow plowing weed eradication area of rice transplanter.Travelling with crawler belt, is that two driving wheels are installed on front axle, draws up at trailing wheel two regulating wheels are installed, and on driving wheel and regulating wheel crawler belt is installed.Crawler belt will be made easily, and is light, does creeper tread with sheet metal, and creeper tread does not weld the both sides of guide and upwards pulls back the obtuse angle that is a bit larger tham the right angle, becomes the track plate, forms track.In addition both sides not with the part of guide welding, pull back right angle or acute angle and obtuse angle downwards, become short blade, the one, prevent to skid, the 2nd, can play the effect of shallow plowing weed eradication.Creeper tread is pulled back the two ends of blade downwards, the centre at creeper tread two ends and the cover welding of having strong market potential, another creeper tread in two, half two ends of narrow this and short guide welding, half wide two ends are by the one side and short guide welding of track plate, and creeper tread in two connects into a creeper tread with a connecting plate and four screws with it.Also can directly will lack guide and be welded on the two sides of creeper tread two ends not in two by the track plate with creeper tread.Be welded in the middle of the creeper tread guide and the guide that is welded on the creeper tread both sides with track pin wear at interval link up crawler belt.Each guide two ends all seals with sealing ring.This is a kind of method of doing crawler belt.The another kind of method of doing crawler belt is, creeper tread is not pulled back the two ends of track plate, one end is narrower, an end broad, and an end is pulled back short blade, the other end is not pulled blade, pull back an end of blade, the part that rail plate long goes out does not cut off or cuts off less, bores track pin at the two ends of track plate and penetrates the hole, with track pin that narrow end of wide this end of creeper tread and creeper tread (narrow be placed on wide inner face) is worn one by one and is linked up, crawler belt.This method crawler belt is done easily, but creeper tread and track pin wearing and tearing are big, bad easily.The third method of doing crawler belt is, it is equally wide that creeper tread is not pulled back the two ends of track plate, one end is pulled back short blade, the other end is not pulled blade, in the track plate front and back of each creeper tread, connect steel plate in the riveted joint respectively and be connected steel plate outward, the connecting hole on the inside and outside connection steel plate promptly is that track pin penetrates the hole, with track pin each creeper tread is worn and to be linked up, crawler belt.This method not only crawler belt is done easily, and inside and outside connection steel plate and track pin change easily, and the time that creeper tread is used is long.

Driving wheel and regulating wheel are made up of axle sleeve, the gear teeth and reinforcing steel ring.The gear teeth of driving wheel and regulating wheel are pulled back triangle with steel bar or steel plate, and the both sides that face toward are welded on the axle sleeve, replace the gear teeth, and it is wide that the width of the gear teeth is slightly less than track.For preventing that the gear teeth from moving, gear teeth both sides all reinforce with the guiding principle circle.Rice transplanter is small and light, can be without supporting wheel and support roller.

The improvement of vertical seedlings sending is, the ratchet at ratchet shaft two ends is become fork, fork links to each other with pull bar, the driving lever at passive sprocket shaft or passive tooth wheel shaft two ends or have the high gear of several teeth to stir fork, be connected the pull bar on the fork, just can spur the seedling feeding claw row who links to each other with pull bar and carry out vertical seedlings sending.Driving lever or when having the high gear of several teeth to break away from fork, spring retracts seedling feeding claw row again.This is a kind of method.Another kind method is, near the seedling case sill of seedling case back, lever shaft is installed, lever shaft passes two seedling case side plates, half of lever fixed at the lever shaft two ends, second half of lever is fixed in the middle of the lever shaft, two connecting rods that link to each other with seedling feeding claw row, one end links to each other with seedling feeding claw row, the other end links to each other with the lever at lever shaft two ends, and the lever in the middle of the lever shaft is by the collision block on seedling-planting manipulator beam and transplant seedlings handle or the seedling-planting manipulator connecting rod or bump nail and pull, and lever shaft rotates, the lever swing at lever shaft two ends, the connecting rod that is connected with lever, the pulling seedling feeding claw row move forward and backward, and carries out vertical seedlings sending.Another way is, two ends and the middle seedling feeding claw row hook of installing seedling feeding claw row, seedling feeding claw row hook is followed closely or collision block pulling and promotion by bumping on seedling-planting manipulator beam and transplant seedlings handle or the seedling-planting manipulator connecting rod, during vertical seedlings sending, bump nail or collision block on two transplant seedlings handle or the seedling-planting manipulator connecting rods promote seedling feeding claw row hook and arrange with seedling feeding claw and carry out vertical seedlings sending, during the seedling-planting manipulator revolution, the seedling-planting manipulator beam retracts seedling feeding claw row's hook and seedling feeding claw row again, treat that the seedling case moves on to when planting on one side the last a brood of seedling of this horizontally-arranged, bump nail or collision block on two transplant seedlings handle or the seedling-planting manipulator connecting rods promote seedling feeding claw row hook again and arrange with seedling feeding claw and carry out vertical seedlings sending.

Square nut is a quadrangle, and screw eye is eccentric.Loosening for preventing square nut, an available elongated steel sheet is pulled back the right angle, and this of right angle face length simultaneously is fixed on the rocking bar, or is welded on the rocking bar, and the face short side in right angle contacts with transplant seedlings handle or seedling-planting manipulator connecting rod.

The seedling box plate can be made of galvanized iron sheet, and the right angle is pulled back on both sides, with screw it is fixed on the seedling case side plate, and a little grooves can be done in the centre, with the power of reducing friction, is beneficial to thin soil seedling downslide seedling sending.

Frame can be made of angle iron, perhaps in the place that roller is installed with an angle iron, the one side of angle iron is connected with frame, another side boring, wear strip or seedling case crossbeam pass from the hole, are fixed on the seedling case side plate again, like this can be without roller, or only on the frame rear pillar, use roller, and allow wear strip or seedling case crossbeam in roller, slide, can use roller less like this.

By these improvement, the one, be convenient to carrying, also increased the driving force of rice transplanter, the 2nd, the weed eradication of can ploughing shallowly in full field, or increase rice transplanter shallow plowing weed eradication area, and the 3rd, work is saved in easier manufacturing, economizes in raw materials, and saves cost.Make the Manpower automatic rice transplanter that has improved have more practicality, be convenient to the peasant and buy use.Crawler belt and driving wheel and regulating wheel are made easily, not only can be used for Manpower automatic rice transplanter, also can be used for other rice transplanter and small farm machine.
