Abstract

The invention provides a split type soil-breaking subsoiler capable of being independently adjusted, aiming at avoiding the phenomena of large soil blocks, uneven ground surface, influence on subsequent operation and soil moisture loss under the conditions of dry soil and thick soil layer of subsoiling; the soil crushing wheel is reasonable and compact in structure and comprises a rack, an upper suspension, a lower suspension, a U-shaped clamp, a subsoiler clamping plate welded together, a subsoiler rod, a subsoiler tip, a soil crushing wheel outer connecting plate, a soil crushing wheel inner connecting frame, a pin 1, a soil crushing wheel supporting plate, a soil crushing wheel assembly, a soil crushing wheel tip and a pin 2; the invention is connected with the rear suspension of the tractor, and the lifting of the implement is controlled by the suspension system according to the requirement of the subsoiling depth during operation, the working positions of all working parts of the invention can be adjusted according to the subsoiling ridge distance position, the implement continuously advances under the driving of the tractor, the subsoiling shovel carries out subsoiling, the rear soil crushing wheel assembly rolls and advances, and the soil blocks appearing in the subsoiling process are crushed and pressed.

Description

Split independently-adjustable soil crushing subsoiler

Technical Field

The invention belongs to the field of agricultural machinery, and relates to a subsoiler;

background

Deep scarification is a new farming system combining agricultural machinery and agriculture, and is one of main technologies for protecting farmland. The deep scarifier is widely used for deeply loosening cultivated land, can effectively break a hard plough layer formed under the conditions of ploughing, stubble cleaning, repeated ground-entering operation of large-scale machinery and the like for a long time, effectively improves the water permeability and air permeability of soil, improves the infiltration rate of rainfall and increases the water storage capacity of the soil. The structure of the subsoiler produced in China at present mainly comprises a frame, a subsoiler handle, a shovel tip, an adjusting wheel, an upper suspension pin and a lower suspension pin, but the subsoiler with the structure has the following problems that (1) during operation, the subsoiler is easily blocked by sundries before shoveling, and the operation quality is influenced; (2) the dry and deep-loosening soil layer is thick, so that the phenomenon of large soil blocks is easy to occur, the ground surface is uneven, the subsequent operation is influenced, and meanwhile, the soil moisture loss is easy to cause;

disclosure of Invention

The invention aims to overcome the defects and shortcomings in the prior art, and provides the subsoiler which is simple in structure, convenient to operate and convenient to popularize and apply.

The invention is realized by adopting the following technical scheme: 1. mounting four outer connecting plates of the soil crushing wheel to the rear part of the frame through pins; 2. arranging the soil crushing wheel tips in sequence into a straight line and uniformly welding the straight line to the soil crushing wheel part; 3. mounting a soil crushing wheel support plate on the welded soil crushing wheel part through a pin; 4. installing the left soil crushing wheel and the right soil crushing wheel which are provided with the soil crushing wheel supporting plates on the soil crushing wheel outer connecting plates by using pins; 5. the frame is hung on a tractor and then hung at three points, the left lower hanger and the right lower hanger on the lower part of the frame are firstly installed, then the upper hanger on the upper part of the frame is installed, and the hangers are positioned at the highest floating position; 6. installing the deep scarification shovel clamping plate welding parts on the rack through U-shaped clamps, fixing the six deep scarification shovel clamping plate welding parts through the U-shaped clamps after the installation positions of the six deep scarification shovel clamping plate welding parts are set according to the ridge spacing condition of the cultivated land, and adjusting the spacing at any time through loosening and tightening the U-shaped clamps according to the variation of the cultivated land; 7. welding the subsoiler tip to the subsoiler rod; 8. six subsoiler rods with welded shovel tips are sequentially fixed to a subsoiler clamping plate through screws.

The invention has reasonable and compact structure and convenient installation and use, breaks the plough bottom layer, recovers the soil plough layer structure, is used for mechanized plowing of deep soil cultivation among rows, improves the water storage and soil moisture conservation capability of soil, eliminates partial weeds, levels the ground surface, promotes grain growth, improves the agricultural mechanized standard and the like.

Drawings

The invention will be further described with reference to the accompanying drawings.

FIG. 1 is a schematic front view of the present invention;

in the figure: 1. the soil breaking device comprises a rack, an upper suspension, a lower suspension, a U-shaped clamp, a sub-soiling shovel clamping plate, a sub-soiling shovel rod, a sub-soiling shovel tip, a soil breaking wheel outer connecting plate, a sub-soiling shovel clamping plate and a pin, wherein the sub-soiling shovel clamping plate is welded to the rack, the sub-soiling shovel rod is welded to the sub-soiling shovel tip, the sub-soiling shovel tip is welded to the sub-soiling shovel clamping plate, the sub-soiling shovel tip is welded to the sub-soiling shovel 8, a soil breaking wheel outer connecting plate is welded to the sub-soiling shovel;

detailed description of the preferred embodiments

As shown in figure 1, the invention can complete the operation by driving a tractor through a frame 1, an upper suspension 2, a lower suspension 3, a U-shaped clamp 4, a subsoiler clamping plate 5, a subsoiler rod 6, a subsoiler tip 7, a soil crushing wheel external connecting plate 8, a soil crushing wheel internal connecting frame 9, a pin 1, a pin 11, a soil crushing wheel supporting plate 12, a soil crushing wheel assembly 13, a soil crushing wheel tip 14 and a pin 2.

The above technical features constitute the best embodiment of the present invention, which has strong adaptability and implementation effect, and unnecessary technical features can be increased or decreased according to actual needs to meet the requirements of different situations.
