So that suppression roller 11 two ends are located at same level position, it is ensured that suppression roller 11 in operation can level soil is carried out it is high
Multi-mass work.
The drive connection of transmission mechanism is that fertilizing mechanism is connected transmission by chain with suppression roller, and drive sprocket is installed
On suppression roller, drive sprocket is rotated by chain-driving bridge sprocket 15, and bridge sprocket 15 is arranged in rotary tillage frame 16,
Bridge sprocket 15 is rotated by chain-driving driven sprocket 14, and driven sprocket 14 is arranged on the fertilizer expelling shaft of shallow-layer fertilizing box 9, shallow
Layer fertilizing box 9 fertilizer expelling shaft on two intermediate transmission sprocket wheels are installed, by chain respectively with two power transmission shafts of subsoiling fertilizing box 7
The driven sprocket 14 of upper installation is connected.
Using tractor as the drive mechanism of subsoiling rotary tillage combine, according to the fertilising of soil requirement in subsoiling fertilizing box
7 and shallow-layer fertilizing box 9 in be put into different fertilizer, regulate subsoiling spade 3 spade seat 2 position, determine the depth of subsoiling,
Tractor is pulled during operation machine operation, the subsoiling of subsoiling spade 3, and the fertilizer of subsoiling fertilizing box 7 is entered by whole layer placement of fertilizer pipe 4
Whole layer placement of fertilizer groove 5, is then applied fertilizer by fertilizer applying hole to 20~30cm of depth of soil soil, the pipe 6 while first floor applies fertilizer
Another fertilizer is applied in soil shallow-layer, shallow-layer fertilizing box 9 below applies the third fertilizer by the plate that applies fertilizer, then rotary cultivator
Fertilizer is threaded onto in 0 to 15cm soil horizon by 8 progress rotary tillage process, it is possible to achieve thin solum applies fertilizer；Soil after rotary tillage is again
Soil is flattened by the suppression effect for suppressing rod 10 and suppression roller 11, it is thus disposable to complete subsoiling, rotary tillage, holostrome
Give fertilizer and suppression operation.
It should be noted that the present embodiment not limits the present invention, subsoiling spade of the invention is in spade seat by spacing
Hole carries out position restriction so as to change subsoiling spade in the position of spade seat with bolt, and subsoiling can also be realized by other means
Spade spade seat relative position change, as long as position change be by subsoiling spade spade seat fixed form change i.e.
Can；The whole layer placement of fertilizer groove of the present invention is to be arranged separately in behind subsoiling spade, and this is for the ease of dismounting and repairing, certainly
Whole layer placement of fertilizer groove and subsoiling spade can be made integrative-structure, have no effect on the effect of subsoil application.
Specific case is applied in the present invention to be set forth the principle and embodiment of the present invention, above example
Illustrate the method and its core concept for being only intended to help to understand the present invention；Simultaneously for those of ordinary skill in the art, according to
According to the thought of the present invention, it will change in specific embodiments and applications.In summary, this specification content
It should not be construed as limiting the invention.
