Description

Chemical fertilizer spreader with a long nose

The application relates to a kind of deep applicator that is used for various crops are carried out soil deep placement chemical fertilizer.

Before the application makes, give paddy field and dry field farming thing to fertilize, adopt following several method and utensil:

1, be to adopt traditional manual face of land broadcast application.Adopt hand to grab chemical fertilizer at paddy field and send in the soil, or adopt into the earth depths, adopt wooden spike to beat in dry land and after cave or little spade dig the cave chemical fertilizer is sent in the cave with pin.

2, be to pull the deep placement machine on large-scale farm with tractor to carry out the fertilizer deep placement operation.

3, be a day disclosure special permission, the continuous fertilization device is given crops deep placement chemical fertilizer in the clear 57-65120 employing soil.

The method of above-mentioned dispensing chemical fertilizer is because chemical fertilizer is sprinkling upon the soil surface, and the decomposition of chemical fertilizer is volatilized and be serious with the current mistake, the loss height to percent about 50 of nitrogen.

Though what have can accomplish fertilizer deep placement, operating efficiency is very low, and labour intensity is big.

The 2nd kind of way can only be given part crops deep placement chemical fertilizer in the large tracts of land soil, to the paddy rice in the small size soil, vegetables, cotton, corn, nursery stock etc., and other to have grown the higher crops of soil dispensing chemical fertilizer then powerless.

The 3rd kind of day disclosure special permission, the continuous fertilization device is compared with manual fertilising in the soil of clear 57-65120, has improved efficiency, alleviated labour intensity, but this utensil can not force chemical fertilizer to enter mechanism in the soil, so it can not be used for paddy field deep placement chemical fertilizer.This utensil does not have gusset, and deep placement chemical fertilizer operator requires great effort very much in harder soil.Power.The chemical fertilizer storage cylinder of this utensil is that the top is big, the bottom is a straight tube.Therefore, the center of gravity height is not easy to operate, and chemical fertilizer by the time be easy to generate clogging.This utensil can only singlely use, and operating efficiency is lower.

The application's purpose: provide a kind of fertilizer deep placing device, be used for various crops are carried out soil deep placement powder shape chemical fertilizer.

The application's fertilizer deep placing device mainly is made of storage cylinder 1, operating control device, working head a, gusset 37 etc.Storage cylinder 1 is made of by cone top Cylinder m and bottom, is used to store powder shape chemical fertilizer, and with reference to Fig. 1, Fig. 2, operating control device promotes steel wire 6 by action bars 5, drives fork 8 and rotates counterclockwise around square head shaft 9.The left swing arm 11 that meanwhile is contained in square head shaft 9 also rotates counterclockwise, thereby make the ratchet that is contained on swing arm 11 other ends, drive ratchet 19 and be rotated counterclockwise 60 °, also rotate 60 ° with ratchet 19 coaxial distribution wheels 31, at this moment, storage cylinder 1 is entered distribute the chemical fertilizer at h place between wheel 31 blades to be assigned in the working head lower cavity g.Arrive this, its task of metering distributor gear is finished.Referring to Fig. 1,2,3, working head a, be by when left swing arm 11 is rotated, drive left and right push arm 20,20 ' move downward,, drive the inboard of slide block 22 along the wedge side wall e of working head a shell 2 meanwhile by having strong market potential 21, and compression spring 23 is to lower slider, the resistance that this moment, slider head 27 overcame torque spring 30 and extraneous soil is forced from the chemical fertilizer of metering distributor gear, pushes closing door 29 open and enters the depth of soils, reaches the fertilising purpose.When hand is decontroled action bars 5, because the compression spring 23 in the working head is upheld reset response, impel slide block 22 to slide along inboard the going up rapidly of wedge side wall e, promptly produce bump, make chemical fertilizer, also impel the chemical fertilizer that may rest in the cavity g to fall wedge end K place simultaneously from enriching in the storage cylinder 1 to h the blade that distributes wheel 31 with storage cylinder 1 shell, when slide block resets, except that ratchet 19 and distribute wheel 31 still in situ, other movable part also resets simultaneously, for next deep placement chemical fertilizer is got ready.So repeat, just can carry out continual fertilizer deep placement operation.

So far fertilizer deep placing device of the present invention as can be known center technology, it is the chemical fertilizer that will be contained in the storage cylinder, by operating control device, impel the work of metering distributor gear, and chemical fertilizer is sent into working head, thereafter working head passes through maneuver control device simultaneously, make slide block inboard and compress spring,, overcome torque spring and extraneous soil resistance to lower slider along the wedge side wall of working head shell, by force chemical fertilizer is pushed in the soil, thereby finished the single-dose application process.

The application's advantage is that storage cylinder top is little, and the below is big, and center of gravity is low, is convenient to operation, can by force chemical fertilizer be imposed on soil, reliable operation, and in than pan soil earth to fertilize the time, design has gusset.

Simultaneously, this fertilizer deep placing device can be pressed into piece in advance with chemical fertilizer, and chemical fertilizer can prolong diffusion time in soil, allows crops slowly absorb the effect that prolongs fertility to obtain, and to saving fertilizer amount, it is favourable to improve output.

Below center of the present invention technology contents is described in further detail in conjunction with the accompanying drawings.
