Description

Technical Field

[0001] The invention relates to the technical field of straw rotary tillage returning machines, and in particular to a straw rotary tillage returning machine with adjustable rotary burying depth. Background Art

[0002] In order to prohibit straw burning, increase the comprehensive utilization of straw, prevent air pollution and protect the environment, my country has vigorously promoted straw return machines. Straw burning will produce a large amount of harmful gases, such as sulfur dioxide, carbon monoxide and particulate matter, which will cause serious pollution to the atmospheric environment. Straw rotary tillage and return to the field can avoid the occurrence of straw burning from the source and effectively improve the air quality. Straw rotary tillage and return to the field is a mechanical equipment used in agricultural production. Straw rotary tillage and return to the field is an agricultural production technology. It refers to the process of using rotary tillage machinery to directly crush the straw remaining after the harvest of crops and turn it over and bury it in the soil. The purpose is to allow the straw to decompose naturally in the soil, thereby increasing the organic matter content in the soil, improving soil structure, and enhancing the soil's ability to retain water and fertilizer. For example, long-term straw return to the field can make the soil more loose, which is conducive to the growth and development of crop roots.

[0003] When using a straw rotary tillage machine, the straw is usually crushed and then plowed into the soil. Since some soils are too loose, it is difficult for the straw to be buried in the soil during plowing, which affects the effect of returning the straw to the field. Therefore, we propose a straw rotary tillage machine with adjustable burial depth. Summary of the invention

When the inclined scraper rotates, the top of the top scrapes the bottom surface of the liquid storage box to clear the mud, to prevent the bottom surface of the liquid storage box that has been in an atomized and humid environment for a long time from being gradually covered with wet mud, causing blockage and affecting the spraying effect.

[0008] 2. The present invention provides a rotary tillage device, and uses a built-in slide bar to adjust the distance between the rotary tillage blade and the electric roller shaft 2, that is, the rotary burying depth during operation, to prevent part of the soil from being too loose, resulting in difficulty in burying the straw into the soil during tillage, affecting the effect of returning the straw to the field; the oblique bar moves to perform piercing cleaning on the inner area of ​​the square slide hole, to prevent excessive debris from gradually accumulating in the square slide hole after long-term rotary tillage of the straw, causing blockage and affecting the sliding adjustment of the built-in slide bar; the concave scraper performs scraping cleaning on the side of the moving rotary tillage blade, to prevent the surface of the rotary tillage blade from being accumulated with lumps of sludge and other debris after long-term use, which seriously affects the rotary tillage effect of the straw; when the concave scraper rotates at high speed with the circular chuck, the mud and other debris accumulated on the inside are discharged outward through the concave through hole due to centrifugal force, to prevent the concave scraper from gradually accumulating excessive mud and other debris on the inside after long-term use, affecting the cleaning effect of the rotary tillage blade.

The atomized droplets are accelerated to be sprayed and distributed in the rotary tillage operation area by the push of the square pressure plate, so as to prevent the floating atomized droplets from being difficult to penetrate into the rotary tillage operation area due to the large degree of splashing of dust and ash when the straw rotary tillage machine is performing rotary tillage operation. A corrugated ring sheet is provided on the outside of the electric push rod to wrap and cover the electric push rod, so as to prevent the electric push rod from being damaged by water seepage when working in a liquid storage tank filled with water for a long time. The atomizing circular hole 1 and the atomizing circular hole 2 are staggered so that the square pressure plate can effectively push a part of the water flow to be discharged from the atomizing circular hole 1 at an accelerated rate, so as to prevent the squeezed water flow from being unloaded up and down at the same time when the atomizing circular hole 1 and the atomizing circular hole 2 are aligned with each other, and it is difficult to discharge from the atomizing circular hole 1 at an accelerated rate.

[0010] 4. The present invention provides a mud cleaning mechanism. When the inclined scraper rotates, the top of the scraper scrapes the bottom surface of the liquid storage box to clean the mud, so as to prevent the bottom surface of the liquid storage box that has been in an atomized and humid environment for a long time from being gradually covered by wet mud, causing blockage and affecting the spraying effect. When the rotating inclined scraper contacts the atomized droplets, it pushes the atomized droplets to diffuse in a circumferential direction with the linkage disk as the center, so as to prevent the dust and mud from splashing to a large extent when the straw rotary tillage returning machine performs rotary tillage operation, which makes it difficult for the sprayed atomized droplets to float and diffuse to the surrounding area for a secondary time. The hollow air cushion arranged on the side of the inclined scraper elastically contacts the mud and stones splashed in the rotary tillage area before moving, so as to prevent the inclined scraper from colliding and wearing with the mud and stones splashed for a long time in the rotary tillage area to cause damage. By arranging a plurality of buffer springs inside the hollow air cushion, the collision friction force on the hollow air cushion is reduced, so as to prevent the relative friction between the hollow air cushion and the splashed mud and stones for a long time from gradually wearing out its surface.

When the circular chuck 502 rotates, it drives the concave scraper 508 on the side to rotate at high speed together When the concave scraper 508 rotates at a high speed with the circular clamping disc 502, the mud and other debris accumulated inside are discharged outward through the concave through-hole 509 by centrifugal force. When the straw rotary tillage returning machine is performing rotary tillage operation on the straw, the high-pressure water pump 604 is started to pump the water in the concave water tank 601 into the liquid storage tank 605. The water flows into the liquid storage tank 605 and passes through the atomization hole 2 610 on the square pressing plate 608 to enter the bottom of the square pressing plate 608 and then passes through the atomization hole 1 606. After secondary atomization, it is sprayed on the rotary tillage operation area and the cutter disc. The secondary atomization of the atomization hole 1 606 and the atomization hole 2 610 is used to atomize dust reduction in the rotary tillage operation area and lubricate the cutter disc. When the liquid storage tank 605 is filled with water, the electric push rod 607 pushes the direction pressing plate downward. Atomizing hole 2 610 provided on square pressing plate 608 is staggered with atomizing hole 1 606 at the bottom of liquid storage box 605. When square pressing plate 608 moves downward, it pushes a part of atomized water flow to accelerate and spray out of atomizing hole 1 606. The atomized droplets are accelerated to spray out and distributed in the rotary tillage operation area by the push of square pressing plate 608. A corrugated ring piece 609 is arranged on the outer side of electric push rod 607 to wrap and cover electric push rod 607. By staggering atomizing circular hole 1 and atomizing circular hole 2, square pressing plate 608 can effectively push a part of water flow to accelerate and discharge from atomizing circular hole 1. At the same time, mud cleaning mechanism 602 can be used to scrape mud from the bottom surface of liquid storage box 605. Drive motor 6023 is started to drive linkage disk 6025 to rotate.The linkage disk 6025 rotates to drive the outer inclined scraper 6026 to rotate. When the inclined scraper 6026 rotates, the top of the bottom surface of the liquid storage box 605 is scraped to clean the mud. At the same time, the electric slide rail 6022 drives the docking ring 6021 to move horizontally. When the docking ring 6021 moves, it drives the driving motor 6023 and the bottom receiving long plate 6024 to move together with the linkage disk 6025. When the linkage disk 6025 moves, it drives the inclined scraper 6026 on the outer surface to move together to clean different positions of the bottom surface of the liquid storage box 605. When the linkage disk 6025 rotates, the inclined scraper 6026 pushes the accelerated sprayed atomized droplets toward When the rotating inclined scraper 6026 contacts the atomized droplets, it pushes the atomized droplets to diffuse in a circumferential direction with the linkage disk 6025 as the center. When the inclined scraper 6026 rotates, it drives the hollow air cushion 6027 on the side to move together. When the hollow air cushion 6027 is arranged on the side of the inclined scraper 6026, it elastically contacts the mud and stones splashed in the rotary tillage area before moving. When the hollow air cushion 6027 elastically collides with the splashed mud and stones, it compresses the internal buffer spring 6028 to a certain extent. By arranging multiple buffer springs 6028 inside the hollow air cushion 6027, the collision friction force on the hollow air cushion 6027 is reduced.
