Problems solved by technology

[0004] Traditional conventional plows or rotary tillers, paddy field harrows and beaters and other land preparation equipment are not suitable for the requirements of new agronomic techniques, and have a great impact on the mechanized planting of rice. Requirements and technical requirements for ecological management of soda saline-alkali land in Northeast China
[0005] At present, most of the rice straw returning machines in the market are driven. As for the non-driven rice straw full-scale returning machines, which can also improve the soda saline-alkali land, there has not been found yet.

Embodiment 1

[0044] see Figure 1-5 As shown, a rice straw burying machine applied to soda saline-alkali land is combined with a frame, a star-wheel-type soil stirring roller and a disc-type grass roller to adapt to different paddy field soils and surface straw coverage conditions.

[0045] The frame includes a front beam frame 1, a rear beam frame 14, a pull rod 7 and a roller bracket 13, and the two ends of the front beam frame 1 are welded with a horizontal welding plate 4, and the horizontal welding plate 4 is connected to the frame plate through a bolt 10 and a nut 9 5. The frame plate 5 is welded on the front side of the roller bracket 13, the top of the roller bracket 13 is welded with a pressure plate 15, and the rear beam frame 14 is installed above the pressure plate 15, and the rear beam frame 14 is arranged between the two roller brackets 13, and the end of the rear beam frame 14 The upper and lower sides of the back beam frame 14 are fixed by the pressing plate 15, and the pre...

Embodiment 2

[0052] see Figure 10 , Figure 11 As shown, a rice straw burial machine applied to soda saline-alkali land is combined by using a frame and two sets of disc-type grass rollers installed on the frame. The frame and the structure disclosed in Embodiment 1 are the same, and the To adapt to different paddy field soil and surface straw cover conditions.

[0053] The round-hole type stubble-returning roll includes a return-sizing and grass-returning roller 25, a return-sizing hole 26, a side plate 27 and a return-sizing and pressing grass roller shaft 28, and the surface of the returning-sizing and pressing grass roller 25 is evenly provided with several Returning slurry hole 26, returning slurry and pressing grass roller 25 two ends are welded with side plate 27, and side plate 27 is fixed on returning slurry pressing grass roller shaft 28, has beating, the effect of flat ground.

Embodiment 3

[0055] see Figure 12-14 As shown, a rice straw burial machine applied to soda saline-alkali land includes a frame, a star-wheel soil stirring roller, a disc-type grass pressing roller and a round-hole stubble-returning roller for combination. The frame, star wheel The structure of the soil stirring roller, the disc-type grass-pressing roller and the round-hole-type stubble-pressing and slurry-returning roller are the same as those disclosed in Embodiment 1, and are used to adapt to different paddy field soils and surface straw mulching conditions.

[0056] In an embodiment of the present invention, the disc pressing grass roller shaft 20, the soil stirring roller shaft 21 and the returning pulp and grass pressing roller shaft 28 can all be installed in the bearing housing 16 between the roller brackets 13, and the ball bearings 23 Driven by the transmission and the frame to rotate.

[0057] see Figure 1-4 as well as Figure 10 , Figure 12-14 As shown, the results of the...

Abstract

The invention discloses a rice straw pressure burying machine applied to soda saline-alkaline lands and belongs to the technical field of agricultural machinery. The rice straw pressure burying machine applied to the soda saline-alkaline lands solves the problem of lack of non-driven rice straw all returning machines as well as machines and tools for improving the soda saline-alkaline lands. The rice straw pressure burying machine applied to the soda saline-alkaline lands comprises a frame, a star wheel type ploughing roller, a disc type straw pressing roller and a round hole type stubble pressing pulp returning roller, wherein the frame is universal and can achieve random combination of single roller, double rollers and triple rollers to adapt to different paddy field soils and differentsurface straw covering conditions; only powered by a tractor, the rice straw pressure burying machine applied to the soda saline-alkaline lands overcomes the problem of straw twining and blocking of working parts of traditional driven type soil tillage and preparation machines; crop straw is applied to increasing soil fertility, straw stubbles are pressed and buried at the bottom of a plough layerto form a straw isolating layer, which can effectively prevent bottom salt and alkali from moving up, improve the ecological treatment and restoration effects on rice cultivating soil of the soda saline-alkaline lands and achieve the aim of saline-alkaline land improvement; applied working parts are all in a non-driven type, so that power and fuel consumption during operation can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rice straw burying machine applied to soda saline-alkali land. Background technique [0002] Rice is the largest food crop in my country. Its planting methods mainly include transplanting and direct seeding, but both of them have strict requirements on the conditions of the planting surface. The traditional plowing and land preparation method, under the condition of no straw mulch and low stubble height, soaks the field after plowing or rotary plowing, and uses paddy field harrow or beater to meet the technical requirements of plowing before rice transplanting or paddy field direct seeding. In recent years, with the development of the new agronomic technology of returning full rice straw to the field, traditional plows or rotary tillers, paddy field harrows and beaters and other land preparation equipment are not suitable for the new agronomic technology requirem...
