Abstract

The utility model relates to a dynamic seedling-throwing machine for transplanting of rice seedlings, in particular to a wind force seedling-throwing machine. A wind force seedling-throwing machine includes a wind turbine (1), an air outlet (2), a wind force box (3), a seedling inlet (4), a wind force enhancement belt (5) and a seedling outlet (6). When at work, put the machine on the bank of the rice field and power on the wind turbine. Wind passing through the air outlet blows to the wind force box and passes through the wind force enhancement belt and the wind force is strengthened. Put rice seedlings uniformly at the seedling inlet and the seedlings will be blown to the rice field by the wind force. With the help of the machine, seeding efficiency can greatly be enhanced. Moreover, the rice seedlings can be uniformly laid, survival rate and tillering rate being high. In this way, production rate of rice can be increased and working force of farmers can be lowered. Impairment of cold water to the human body can be reduced. The wind force seedling-throwing machine is noted for easy structure, convenient maintenance and low costs. Therefore, the machine is quite suitable for popularization in rural areas.

Description

The two control of piston type fertilizer applicator

Technical field

The utility model belongs to the field of mechanical technique of using in the agricultural production, particularly a kind of fertilizer applicator.

Background technology

The peasant is when using solid, granular chemical fertilizer at present, usually be the soil surface that fertilizer is sprinkled upon crop root part, cover with soil then, by artificial water spray or natural precipitation, make solid fertilizer dissolving back flow into crop root part, thereby absorbed by plant and utilize.Yet this mode can only make a small amount of fertilizer porous to crop root part, a large portion fertilizer still is stranded in the thin solum, walked by rain drop erosion then, or its active ingredient evaporates in the air, thereby cause the significant wastage of chemical fertilizer, and the chemical fertilizer that runs off pollutes to natural environment.For addressing this problem, people have designed a lot of fertilising instruments, with the fertilising instrument chemical fertilizer are executed the plant root soil deep layer, effectively overcome the above problems.But have a lot of different problems in the existing fertilising instrument, what have can not control fertilizing amount, causes fertilising uneven, and plant growth is very different; Also can cause waste when the fertilizing amount that has is excessive; Though the quantitative fertilization that has that also has is controlled, inconvenience is operated and carried to its complex structure, and result of use is not good, because the existence of variety of issue causes the fertilising instrument extensively not promoted in the rural area.

The utility model content

For addressing the above problem, the utility model provides the two control of a kind of piston type fertilizer applicator, and its embodiment is as follows:

The two control of piston type fertilizer applicator is made up of overcoat and movable push bar, and overcoat is cylindrical, and the bottom has through hole, top is stamped and is screwed lid, and push rod passes loam cake and is contained in the overcoat, and handle is arranged at its top, push rod cup is arranged at the bottom, and push rod cup is over against lower through-hole, and the overcoat middle and lower part is installed with neck bush; Be positioned at overcoat, a push rod overhead gage arranged on the push rod that covers an end by screwing; Between neck bush and the push rod overhead gage spring is arranged, be positioned on the push rod of neck bush and be installed with a upper piston cylindraceous, a lower piston cylindraceous is installed on the push rod between upper piston and the push rod cup, and being positioned on the push rod at lower piston two ends has hold-down nut; A charging through hole that runs through overcoat and neck bush is arranged on the side of overcoat, and the inner opening of through hole is between upper piston and lower piston; A depth adjustment nut is equipped with in the below of pusher grip.

As peasant during at field fertilization, hand-held pusher grip, push rod cup is carried the container of a dress storage solid fertilizer down simultaneously, and this container can link to each other with the through hole that flexible pipe and fertilizer applicator put outward; At this moment solid fertilizer can by the charging through hole, slip in the chamber that is surrounded by upper piston, lower piston, push rod and neck bush from accumulator under deadweight; When the peasant chooses the appropriate location of fertilising, this fertilizer applicator can be stood on this position, to pressing down handle, push rod moves downward, push rod cup inserts in the soil, and at this moment, the push rod overhead gage is to the lower compression spring, upper piston and lower piston move down, and the fertilizer in the chamber is slippage downwards under the promotion of deadweight and upper piston; When continuing to advance pusher grip, lower piston skids off from neck bush, owing to there is not the parcel of neck bush, and the last end face of lower piston is the conical surface, the solid material that is between upper piston and the lower piston will hang down from lower piston under the effect of gravity, is accumulated in by in the cavity that end face surrounds on push rod, external bushing, the push rod cup; Continue to advance pusher grip, the depth adjustment nut touches and screws lid, handle is screwed lid and is blocked, this moment, push rod cup inserted the degree of depth certain in the earth, arrive at the appropriate location of plant root, reach fertilising and expected the effect of needs, fertilising person just can unclamp pusher grip, return under the effect of the spring of push rod in external bushing, push rod is up, and at this moment owing to there is bigger gap between push rod cup and external bushing, solid fertilizer will advance in the mud pit from the gap in landing, fertilising person mentions fertilizer applicator, finishes once manual fertilising process.

In operating process next time, the fertilising personnel can repeat above process.

This shows, in fertilising process each time, fertilizing amount is upper piston, lower piston, neck bush, and the volume of the cavity that surrounds of push rod, therefore the size of single fertilizing amount is constant, thereby guaranteed that the fertilising personnel can impose the fertilizer of equivalent to every strain plant, made the growing way in crops even, harvest is good.

In the fertilizer applicator of said structure,, can control the degree of depth in the push rod cup insertion soil by regulating the depth adjustment nut of pusher grip; By regulating the nut of lower piston top and bottom, can control upper piston, lower piston, neck bush, and the volume of the cavity that surrounds of push rod, that is regulate the size of single fertilizing amount.

According to the needs of different plants fertilization effect, the through hole of jacket bottom and push rod cup can be arranged to two kinds of schemes, and promptly the through hole of jacket bottom is circular, and push rod cup is a cone; Or the through hole of jacket bottom is rectangle, and the push rod cup tip is " a 1 " font.

Owing to adopt above-described utility model structure, make the fertilising of crop realize the purpose of quantitative depthkeeping control, thereby it is even to make every strain farm sow growing way, has improved the growth quality in crops, avoided the waste of chemical fertilizer and to the pollution of environment.
