Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a shallow rotary ditcher with active ditching on both sides. Background Technology

[0002] Rapeseed yields are low, resulting in low profits, especially in seedling cultivation. Intensive farming methods such as plowing, rotary tillage, ridging, seedling raising, and transplanting significantly increase production costs, reduce profits, and may even lead to losses. No-till planting extends the rapeseed's growing period in the field, making it unsuitable for multiple cropping and resulting in overall low returns. No-till transplanting, on the other hand, leads to soil compaction during rotary tillage and transplanting, hindering root growth. Furthermore, the low available nutrient content in the soil contributes to premature aging and low yields.

[0003] To improve the production efficiency of rapeseed mechanized operations in the middle and lower reaches of the Yangtze River, and to address the current production problems of uneven seedbeds, poor soil breaking quality, and "sun-drying" that easily occur when using related machinery, resulting in low rapeseed germination rates, there is an urgent need to provide a shallow rotary tiller with active ditching on both sides.

[0024] The unit disc ditching mechanism 2 has a symmetrical structure and includes: a gearbox 201, a gearbox shaft 202, a unit disc mudguard 203, a unit disc mudguard tie rod 204, a side-mounted gearbox 205, a unit disc 206, a plow head 207, and a ditching assembly. The gearbox 201 is installed in the middle of the gearbox shaft 202, and the gearbox shaft 202 is installed on the right side plate 106 and connected to the left side plate 113 at both ends by a shaft. The unit disc mudguard 203 is connected to the unit disc mudguard tie rod 204 by bolts. The unit disc mudguard tie rod 204 is symmetrically installed on the left and right sides of the middle square tube 107 by bolts and connected to the plow head 207 at the bottom by bolts. The side-mounted gearbox 205 is installed on the left side of the left side plate 113 by bolts. The unit disc 206 is symmetrically installed on the left and right sides of the rotary tiller shaft 213 by bolts and connected by bolts. The ditching assembly is installed on the unit disc 206.

[0025] The ditching assembly includes: a unit disc rotary tiller blade holder 208, a left ditching blade 209, a left rotary tiller blade 210, a right rotary tiller blade 211, a right ditching blade 212, a rotary tiller shaft 213, and a ditching blade holder 214; three left ditching blades 209 are evenly mounted on the ditching blade holder 214 in a circumferentially proportional manner using bolts, and are mounted on the left side of the unit disc 206 via shaft connections; five unit disc rotary tiller blade holders 208 are evenly mounted on the unit disc 206 in a circumferentially proportional manner and are connected by welding; five left rotary tiller blades 210 are evenly mounted on the unit disc rotary tiller blade holders 208 in a circumferentially proportional manner and are connected by bolts; five right rotary tiller blades are evenly mounted on the unit disc rotary tiller blade holders 208 in a circumferentially proportional manner; three right ditching blades 212 are evenly mounted on the ditching blade holder 214 in a circumferentially proportional manner and are mounted on the right side of the unit disc 206 via bolt connections.

[0026] like Figure 2 As shown, the 10 rotary tillage blades 211 of the unit disc ditching mechanism 2 are evenly installed on the unit disc 206, and the 6 ditching blades 212 are evenly installed on the ditching blade holders 214. They are connected to the rotary tillage blade shaft 213 and driven to rotate by the rotary tillage blade shaft 213. The rotary tillage blades 211 of the unit disc ditching mechanism contact the soil and perform preliminary ditching. After the unit disc ditching, the plow head 207 device cleans the loose soil at the bottom of the furrow and compacts the furrow walls, creating a drainage furrow with compact walls and a stable shape. After completion, the soil scattered from the ditching is scattered onto the middle box surface. The shallow rotary mechanism 3 then performs rotary tilling on the soil.

[0027] The shallow rotary mechanism 3 has a symmetrical structure and includes: a flange 301, a left shallow rotary blade 302, a right shallow rotary blade 303, and a shallow rotary blade holder 304. The flange 301 is installed on both sides of the rotary tiller shaft 213 and connected to the right side plate 106 and the left side plate 113 by bolts. 28 shallow rotary blade holders 304 are evenly welded to the rotary tiller shaft 213 in a clockwise spiral pattern, and 28 shallow rotary blade holders 304 are evenly installed on the rotary tiller shaft 213 in a counterclockwise spiral pattern. 28 left shallow rotary blades 302 are evenly installed on the clockwise spiral shallow rotary blade holders 304 and connected by bolts. 28 right shallow rotary blades 303 are evenly installed on the counterclockwise spiral shallow rotary blade holders 304 and connected by bolts.

[0028] like Figure 4As shown, the shallow rotary mechanism 3 is connected to the support mechanism 1 and the unit plate ditching mechanism 2. The shallow rotary mechanism 3 is installed behind the support mechanism 1 and between the two unit plate ditching mechanisms 2. The soil that is thrown onto the middle bed surface by the unit plate ditching mechanism is rotated by the left and right blade rollers of the shallow rotary mechanism, which drives the shallow rotary blade 303 to work. The operation of the shallow rotary blade makes the soil thrown by the rotary tillage blade 303 of the unit plate ditching mechanism on both sides evenly cover the bed surface. The shallow rotary blade operates by cutting the surface soil and straw of the uncultivated land, making the soil on the working bed surface finely broken and the soil and straw evenly mixed.

[0029] The press roller mechanism 4 is a symmetrical mechanism, including: a left telescopic rod 401, a left telescopic rod connecting sheet metal part 402, a right telescopic rod connecting sheet metal part 403, a right telescopic rod 404, a scraper connecting sheet metal part 405, a press roller shaft 406, a scraper 407, and a press roller 408; the lower end of the left telescopic rod 401 is welded to the left side square tube 111 of the press roller and passes through the left telescopic rod connecting sheet metal part 402; the lower end of the right telescopic rod 404 is welded to the right side plate 109 of the press roller and passes through the right telescopic rod connecting sheet metal part 403; the right telescopic rod connecting sheet metal part 404... 03 is symmetrically connected to the right telescopic rod 404, the left telescopic rod 401, and the left telescopic rod connecting sheet metal part 402; one end of the scraper connecting sheet metal part 405 is connected to the right side plate 109 of the pressing roller by bolts, and the other end is connected to the scraper 407 by bolts and installed on the left and right sides of the scraper 407; the pressing roller shaft 406 is connected to the pressing roller 408 by a key, and is connected to the left side square tube 111 of the pressing roller and the right side plate 109 of the pressing roller; the pressing roller is installed between the left side square tube 111 of the pressing roller and the right side plate 109 of the pressing roller via the pressing roller shaft 406.

[0030] like Figure 6 As shown, the pressing roller mechanism 4 is connected to the support mechanism 1. The pressing roller mechanism 4 is symmetrically installed behind the support mechanism 1. The soil that has been broken up by the unit disc trenching mechanism 2 and the shallow rotating mechanism 3 is leveled by the up and down floating of the telescopic rod pressing roller 408. The soil on the box surface is then cleaned by the scraper. The pressing roller compacts and flattens the box surface to achieve a suitable soil porosity and create good conditions for rapeseed seed implantation.

[0031] This invention solves the problems of uneven soil coverage and uneven seedbed surfaces, which are unsuitable for the simplified and efficient production of rapeseed. Designing a rapeseed seedbed preparation device suitable for efficient rapeseed production is of great significance. This device involves opening furrows on both sides, throwing soil from the furrows to cover the middle seedbed, and using a shallow-rotating soil-mixing component to evenly distribute and finely break up the soil on the seedbed surface, mixing the soil and straw evenly. This efficient operation creates favorable conditions for rapeseed seed implantation.

[0032] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
