Embodiment Construction

[0021] specific implementation plan

[0022] The present invention will be described below through embodiments in conjunction with the accompanying drawings.

[0023] As shown in the figure, the auxiliary soil covering mechanism of the seeding mechanism is mainly composed of a soil retaining plate 1, a soil guide plate 2, a ground wheel 3, a sprocket 4, a chain 5, a ground wheel frame 6, a frame 7, a U-shaped card 8, and a ditch. Device shovel handle 9, locking screw rod 10, trousers 11, chain 12, soil setting wheel 13, bracket 14, bolt 15, sprocket wheel 16, seed pipe 17, bolt 18, bearing 19, shaft 20, shaft 21, chain Wheel 22, sprocket wheel 23, axle 24, opener 25, bearing 26, bearing 27 and welding plate 28 etc. are formed.

[0024] The seeding mechanism mainly includes a frame 7, a ground wheel frame 6 installed on the frame 7 through a U-shaped card 8, the ground wheel 3 is connected with the ground wheel frame 6 through a bearing 19 and a shaft 20, and the trousers 11 a...

Abstract

The invention discloses an assistant soil sealing mechanism used with seeder colter boot, which belongs to the technical field of agricultural machine. The technical scheme is that: the invention comprises two thumbwheels (13) and an earth-moving board (2) respectively positioned at two sides of the colter boot (25) of the seeding mechanism as well as a power transmission mechanism connected with the thumbwheels (13); wherein, the two thumbwheels (13) are arranged at inner side in front part of the earth-moving board (2). Compared with the traditional colter boot, the invention is unnecessary of mounting additional soil sealing mechanism; besides, with the rational design of the thumbwheels and the earth-moving board, the device can smoothly get back thee soil excavated by the colter boot without excavating the soil around, therefore, the device can preciously ensure the consistency of the soil depth after seeding and reduce the water lose due to the excavation of the soil during seeding by the machines and tools as less as possible, thus improving the crop seedling emergence and effectively facilitating the implementation of the seeding without ploughing.

Description

technical field [0001] The invention relates to an auxiliary soil-covering mechanism matched with a seeder ditch opener, belonging to the technical field of agricultural machinery. technical background [0002] With the continuous development of the level of agricultural mechanization in our country, the requirements for the level of agricultural mechanization are getting higher and higher, and the development of agriculture needs to take the road of sustainable development. [0003] my country is one of the main arid agricultural countries in the world, in which arid and semi-arid areas account for 52.5% of the country's cultivated land, mainly concentrated in 16 northern provinces. Therefore, the lack of water in the soil has become the main problem of crop growth, and the emergence of spring crops is the most critical of the entire crop growth process. Insufficient water makes it impossible to complete the sowing operation, which affects the emergence rate of crops. In t...
