Problems solved by technology

[0005] Therefore, the technical problem to be solved in the present invention is to overcome the inconsistency of seedling emergence time and irregular seedling emergence and the waste caused by the increased seeding rate of the small seed crop seeder in the prior art when the terrain is uneven or the soil humidity is larger. defects, so as to provide a sowing cover soil device and small grain crop seeder with consistent seedling emergence time and relatively neat seedling emergence time and no need to increase seeding rate when sowing in uneven terrain or high soil humidity

Embodiment 1

[0043] Such as figure 1 As shown, this embodiment provides a seeding cover, which is suitable for installation on a small-grain crop planter, including:

[0044] The seeding tube 1 includes a seed inlet and a seed outlet 11. The seed inlet is in communication with the seed bin 3 of the small-grain crop planter, and the seed outlet 11 is suspended relative to the soil surface;

[0045] The linear covering soil structure is connected to the seeding tube 1 and moves together with the seeding tube 1 to form a linear ravine on the soil parallel to the seeding path of the seeding tube 1 to push the soil against the The seeds falling on the soil in the sowing tube 1 are covered with soil.

[0046] The above-mentioned seeding cover soil device, because the seed outlet 11 of the seeding pipe 1 is suspended relative to the soil surface, the seeds are sown on the ground or shallowly on the ground during sowing, and then the linear cover soil structure connected to the rear of the seeding pipe 1...

Embodiment approach

[0052] As a specific embodiment, the rake 2 includes:

[0053] The connecting rod 21 is fixedly connected to the seeding tube 1;

[0054] There are at least two rake teeth 22, one end of the rake teeth 22 is fixedly connected to the connecting rod 21, and the other end extends downward to contact the ground.

[0055] The above-mentioned tooth rake 2 structure, on the one hand, can realize linear cover soil through the elongated rake teeth 22, and the linear cover soil can not only cover the sown seeds, but also reduce the amount of soil discharged due to the height of the terrain. It can avoid the accumulation of seeds and uneven emergence of seedlings. At the same time, the long strip rake teeth 22 are not easy to stick to the mud; on the other hand, due to the gap between the rake teeth 22, field weeds or slightly larger soil blocks can be rake from the teeth. 2 The gap between the periphery or the rake teeth 22 can pass smoothly, so as to avoid the influence of hanging grass and ...

Embodiment 2

[0067] Such as figure 1 As shown, this embodiment provides a small-grain crop planter, including:

[0068] Rotary tiller 4;

[0069] The seed bin 3 is fixedly connected to the rotary tiller 4 through a bracket; and

[0070] The seeding cover described in Example 1.

[0071] In the above-mentioned small-grain crop planter, since the seeding port 11 of the seeding tube 1 is suspended relative to the soil surface, the seeds are sown on the ground or shallowly on the ground during sowing, and then through the linear cover soil connected to the rear of the seeding tube 1 The structure is to form a linear ravine on the soil to complete the sowing of the seeds falling on the soil with a linear cover, which can successfully complete the sowing under different flat terrain and / or different soil moisture, and achieve better seedling emergence This method of sowing and covering soil will not cause the seeds to be distributed in the soil too scattered and different in depth, so that a better see...

Abstract

The invention provides a sowing and earth-up device and a small-grain crop sower. The small-grain crop sower comprises a rotary cultivator, a seed bin fixedly connected with the rotary cultivator through a support and the sowing and earth-up device. The sowing and earth-up device comprises a sowing tube and a linear earth-up structure, wherein the sowing tube comprises a seed inlet port and a seed outlet port, the seed inlet port is communicated with the seed bin of the small-grain crop sower, and the seed outlet port is suspended relative to the soil face; the linear earth-up structure is connected to the sowing tube, moves together with the sowing tube and pushes soil to earth up the seeds falling from the sowing tube to the soil in the mode of forming linear furrows parallel to the sowing path of the sowing tube in the soil. The small-grain crop sower can smoothly complete sowing under the conditions of terrain of different flatness and different soil humidities, a good seedling emergence effect is achieved, it is ensured that seedling emergence time of the seeds is uniform, and the seedlings are neat and are arranged in rows.

Description

Technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a seeding cover soil device and a small-grain crop planter. Background technique [0002] With the development of social urbanization in my country, there is a serious shortage of rural labor. Therefore, the fundamental way out for agriculture lies in mechanization. The development of efficient and high-yielding mechanized planting methods is an inevitable trend of modern agricultural development. [0003] At present, there are certain products on the market for small-grain crop planters such as sesame and rapeseed, but the effect of seedling emergence is unstable in practical applications. For example, sesame seeds have small grains and poor soil-topping ability. They are too deep into the soil to emerge after sowing. Therefore, in hilly areas and other uneven terrain, it is difficult to set the position of the seeding tube in advance. If it is set too low, the higher p...
