Auxiliary covering mechanism of sowing mechanism

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...

Therefore, the lack of moisture in the soil has become the main problem of crop growth, and the emergence of crops in spring is the most critical in the whole crop growth process. Insufficient water can not complete the sowing operation, which affects the emergence rate of crops

In the traditional sowing method, since the opener divides the soil to both sides of the opener, and then relies on the cover device to cover the soil on both sides to the sowing belt, the water loss is serious, and the depth of the cover is difficult to control, resulting in the emergence of seedlings. , poor consistency of emergence height or low emergence rate
