Description

Deep fertilization adjustment device for walk-behind tractor

technical field

The utility model relates to agricultural machinery, which is a deep fertilization regulating device for a walking tractor.

Background technique

At present, in the mountainous and semi-mountainous areas of our country, most of the farmland is sloping land, and the promotion of large-scale planting machinery for farmland preparation and fertilization is limited. Only small-scale agricultural machinery can complete the operation requirements of farmland preparation and fertilization. At present, more fertilizers with high nitrogen content or compound fertilizers with high content are used as base fertilizer in farmland. Due to the high content of fertilizer and the short distance between the applied fertilizer and the sown seeds, it is easy to cause burning of seeds and seedlings. Affect the emergence rate of crops, reduce the seedling preservation rate of bottom crops, and the phenomenon of lack of seedlings and broken bars occurs from time to time, resulting in reduced crop production. Due to the long-term use of small machinery for soil preparation, the plow layer becomes shallower and a hard plow bottom layer is formed, which makes it difficult for roots to grow through the plow bottom layer, restricting the growth and development of crop roots, resulting in smaller root growth, which greatly affects crop yield and quality. Although the utility model patent No. ZL2012202248578 discloses a "multi-plough cultivator", the depth-of-cultivation adjustment mechanism of "the nut fixed in the plow arm is connected with the fixed-axis rotating screw" can adjust the depth of cultivation, but the long-term The application of small machinery for soil preparation results in a shallow plow layer, resulting in ridges and shallow fertilization of the farmland, which significantly reduces the utilization rate of chemical fertilizers. At the same time, it is easy to cause premature aging of the crops or lodging of the plants, which seriously affects the yield of the crops.

Contents of the invention

The technical problem to be solved by the utility model is: to overcome the shortcomings of the existing base fertilizer fertilization technology, to provide a tractor with simple structure, good stability, convenient assembly, easy operation, easy to implement deep fertilization, and improve the utilization rate of chemical fertilizers. The fertilization adjustment device is suitable for applying base fertilizer to crops in upland fields to achieve precise fertilization and uniform fertilizer application. It can break the bottom of the plow, improve the vitality of crop roots, increase the distance between seeds and chemical fertilizers, and avoid burning seeds and seedlings.

The solution of the utility model to solve the technical problem is: a deep fertilization adjustment device for a walking tractor, which is characterized in that it includes a beam, a coulter, a cross arm and a fertilization tube, the beam is a columnar body, and the two coulters are respectively Placed at both ends of the crossbeam, the crossarm is placed between the crossbeam and the coulter, one end of the crossarm is fitted in the crossbeam and is slidably connected, the other end is fixedly connected with the coulter, the locking screw is threaded with the crossbeam, and the end is connected with the crossbeam arm contact, the fertilization cylinder is placed behind the coulter and is fixedly connected with the coulter.

The tillage depth adjustment mechanism of the coulter is that the nut fixedly connected in the plow arm is connected with the fixed axis rotating screw rod.

The coulter plowing depth adjustment mechanism is also provided with a locking screw, and its structure is: the locking screw is threadedly connected to the plow arm, and the end is in contact with the fixed-axis rotating screw.

The coulter plowing depth adjustment mechanism is also provided with a handle, and its structure is: the handle is fixedly connected with the end of the fixed-axis rotating screw rod.

The handle is a wheeled handle.

The utility model uses a deep fertilization adjustment device for a walking tractor. The structure of the sliding connection between the cross arm and the cross beam can adjust the distance between the two coulters to meet the fertilization needs of different ridge distances. The plowing depth adjustment mechanism of the coulter can The depth of the coulter is adjusted by connecting the fixed nut in the plow arm with the fixed-axis rotating screw. The wheel handle makes the adjustment of the plowing depth more convenient. The tractor is fixedly connected, and the coulters are adjusted to a suitable distance according to the distance between the ridges, and then the plowing depth of the coulters is adjusted according to the depth of the furrows, so that the operations of farmland preparation and fertilization can be carried out. The fertilization depth exceeds 12 cm from the soil surface to achieve precise fertilization and uniform fertilization. It can break the bottom of the plow, improve the root activity of crops, increase the distance between seeds and chemical fertilizers, and avoid burning seeds and seedlings. The utility model has the advantages of simple structure, good stability, convenient assembly, easy operation, easy implementation of deep fertilization, and improved utilization rate of chemical fertilizers.
