Description

Double layer fertilization rotary tillage seeder

Technical field

The utility model relates to a seeder.

Background technique

At present, most of the existing wheat planters use a rotary tiller to prepare the soil before sowing, and then apply fertilizer at the same time of sowing, which can ensure the nutrient requirements of crop seedling growth. The demand increases and topdressing is required. When topdressing crops in the mid-growth period, most areas in my country still use the throwing method to sprinkle chemical fertilizers on the ground, resulting in volatilization and loss of chemical fertilizers, and the effective utilization rate is only about 30%. Compared with the average effective utilization rate of chemical fertilizers in developed countries in the world, which is 60%, There is a big gap. Nutrients cannot be fully absorbed by the roots of crops, resulting in a large amount of chemical fertilizer being wasted; topdressing also requires manpower and material resources, which increases the cost of food production. The latest test shows that if the deep layer fertilizer is applied at the same time of sowing, the grain output can be significantly increased, and the topdressing operation can be saved; the utility model combines the three processes of rotary tillage, double-layer fertilization, and sowing into one, which can effectively reduce the entry of machines into the ground The number of times, improve soil moisture retention capacity. Such joint operations can not only achieve high efficiency and low consumption of operations, but also effectively promote and promote the implementation of fertilizer deep application technology, which is an effective measure to increase agricultural production and save costs and increase efficiency. Therefore, the design of double-layer fertilization rotary tillage seeder meets the requirements of agronomic production increase.

Contents of the invention

In order to apply deep and shallow layers of fertilizer at the same time of sowing, the utility model provides a double-layer fertilization rotary tillage seeder. The planter sows seeds while preparing the soil with rotary tillage, and at the same time applies chemical fertilizers layered into the soil layer at a specific depth. The utility model is composed of a rotary tillage device, a suspension device, a ditch opener, a suppression device, a seed pipe, a fertilizer pipe, and a bottom fertilizer pipe, etc., and completes multiple processes such as rotary tillage, double-layer fertilization, sowing, and suppression in one operation.

The technical solution adopted by the utility model to solve its technical problems is: during the operation process, the rotary tiller shaft is powered by the tractor to drive the rotation, the deep fertilization device is installed on the rear beam of the rotary tiller, and the deep ditching shovel handle and The bottom fertilizer pipe is connected in sequence, followed by the fertilization and seeding device, and the ditch is opened with a shovel opener. To connect back and forth, and then use the adjustable device to connect the seed fertilizer pipe with the seed pipe in sequence, and the seed drop port of the seed pipe can be adjusted above the fertilizer outlet of the seed pipe. The fertilizer outlet of the seed fertilizer pipe is adjustable 15-25cm above the outlet of the base fertilizer pipe, and the front and back connections between the base fertilizer pipe and the ditching shovel handle improve the strength of the ditching shovel handle. When planting and fertilizing, the base fertilizer pipe is deep into the soil, which ensures that the fertilizer is not easy to volatilize and the nutrients can be fully absorbed by the roots of the crops. At the same time, it also achieves the effect of loosening the soil. However, because the deep fertilization device is deep into the soil, the traction resistance Therefore, according to the traction power and the nutrient requirements of wheat, two or three rows can be used to share a deep fertilization device. Because the rotary tillage is performed before deep fertilization, the soil layer of 10-15cm is soft, which can also reduce the resistance on the handle of the deep ditching shovel, thereby reducing the required power. In order to make the deep fertilization device not only easy to enter the soil, but also receive less resistance in the process of advancing, the deep ditching shovel uses a narrow wing type ditching shovel.

The beneficial effects of the utility model are: double layer fertilization can greatly reduce the loss and waste of chemical fertilizers at the same time of sowing, and the nutrients can be fully absorbed by the roots of the crops, which is beneficial to the growth in the middle and late stages, so that the whole growth period will not lose fertilizer, The effect of increasing production is remarkable; it can realize the positioning and isolation of seed fertilizers to avoid burning seeds; improve work efficiency, reduce costs, and reduce labor intensity; uniform and accurate fertilization; it can also reduce the pollution of chemical fertilizers to the environment.

Detailed ways

In the embodiment shown in the accompanying drawings, the shaft of the rotary tiller is powered by a tractor to drive the rotation, and the deep opener (3) is installed on the rear beam of the rotary tiller (1), and the depth of entry into the soil is adjustable. (3) and the base fertilizer pipe (8) are connected in sequence, followed by the sowing device. The sowing device uses a shovel-type ditch opener for ditching. The fertilizer pipe (5) is installed and connected to the shallow ditching shovel handle (4) through a fixed card, the seed fertilizer pipe (5) and the seed pipe (6) are fixedly connected in front and rear order through an adjustable device, and the seed pipe (6) and the seed pipe (6) are fixedly connected in sequence. The depth of the fertilizer pipe (5) into the soil can be adjusted, and the seed drop port of the seed pipe (6) can be adjusted between 3-7cm above the fertilizer outlet of the seed pipe (5). During operation, the seed can be adjusted according to the amount of fertilizer applied. , fertilizer spacing to avoid burning seeds. The base fertilizer is applied to 25-40cm underground through the base fertilizer pipe (8), and the soil returns to the soil naturally. The fertilizer flowing out from the seed fertilizer pipe (5) falls on the top 15-25cm of the fertilizer flowing out from the base fertilizer pipe (8), and the base fertilizer is used for crops. The growth needs in the middle and late stages, and the fertilizer is used for the growth of crops in the seedling stage.
