Description

Technical Field

[0001] The utility model relates to a sowing device for integrated wheat, corn, water and fertilizer, in particular to a shallow buried drip irrigation laying device for a wheat seeder. Background Art

[0002] I. Wheat cultivation: Water resources are scarce in the North China Plain. In recent years, the shallow buried drip irrigation watering method in arid areas of the northwest has been introduced. The upper and lower crop rotations do not integrate. The shallow buried drip irrigation only considers the convenience of wheat watering. After harvesting wheat, the row spacing of the next crop of corn is not integrated with that of the previous crop of wheat, and the watering row spacing of corn does not match that of wheat watering. It can only be used for one season a year. For example, if summer corn uses the shallow buried drip irrigation belt to re-lay, it will waste labor and drip irrigation belts and delay watering after sowing summer corn.

[0003] II. The application laying devices of shallow buried drip irrigation belts are diverse, and the laying row spacing and soil covering are not standardized. There is no unified standard, and there is a lack of a shallow buried drip irrigation belt laying device that can save water and labor and integrate the upper and lower crops of wheat and corn. Content of the Utility Model

[0004] In order to solve the above technical problems, an embodiment of the utility model provides a shallow buried drip irrigation laying device for a wheat seeder. The technical solution is as follows:

[0005] A shallow buried drip irrigation laying device for a wheat seeder includes a frame, and a large bracket that can be adjusted to rise / fall is installed on the frame. It is characterized in that a pressing roller is provided on the large bracket, and a plurality of ditch pressing devices are arranged at intervals along the axial direction on the outer circumference of the pressing roller. The ditch pressing devices press out grooves for laying drip irrigation belts on the land, and the height and width of the ditch pressing devices match the buried depth of the drip irrigation belts and the diameter of the drip irrigation belts;

[0006] Above the pressing roller, there is a drip irrigation belt reel, and the number of drip irrigation belt reels matches the number of ditch pressing devices. The drip irrigation belt reels are installed on a reel bracket, and the reel bracket is installed on the large bracket;

[0007] At the rear upper part of the pressing roller, at a position corresponding to the ditch pressing devices, there is a drip irrigation belt laying device. The middle part of the drip irrigation belt laying device is provided with a drip irrigation belt conduit that penetrates up and down. The upper port of the drip irrigation belt conduit is vertically upward, and the lower port of the drip irrigation belt conduit extends deep into the groove below the ground surface. The drip irrigation belt on the drip irrigation belt reel is inserted from the upper port of the drip irrigation belt conduit, extends out from the lower port of the drip irrigation belt conduit and is buried in the groove below the ground surface;

[0008] Behind the drip irrigation belt laying device, there is a soil covering device, and the lower end of the drip irrigation belt laying device is located below the soil covering device.

[0009] Further, the ditch pressing device is a protrusion arranged on the outer circumference of the pressing roller.

[0010] Furthermore, the protrusion is rectangular, with a height from the surface of the pressing roller ranging from 2.5 cm to 3 cm and a width not less than 2 cm.

[0011] Furthermore, the drip irrigation tape layer extends in a curved shape from top to bottom, and its outer thickness gradually decreases. The lower end extends backward away from the pressing roller and is in a horizontal state, parallel to the ground and extending into a groove below the ground.

[0012] Furthermore, there are two left and right side plates provided at the rear edge of the drip irrigation tape layer. Along the curved direction, a number of first hinge holes are spaced on the side plates. The first hinge holes penetrate through the left and right side plates. A first four-link copying support arm and a second four-link copying support arm are respectively hingedly connected to the first hinge holes. The first four-link copying support arm is located above the second four-link copying support arm.

[0013] Furthermore, a second hinge hole is provided at the other end of the first four-link copying support arm, and a third hinge hole is provided at the other end of the second four-link copying support arm. A first hinge shaft is inserted into the second hinge hole to hingedly connect the first four-link copying support arm to the large bracket. A second hinge shaft is inserted into the third hinge hole to hingedly connect the second four-link copying support arm to the large bracket.

[0014] Furthermore, on one side of the drip irrigation tape layer near the pressing roller at the front, a hanging member and a tension spring are also provided. The upper end of the tension spring is hung on the hanging member, and the lower end of the tension spring is hung on the first hinge shaft.

[0015] Furthermore, the upper port of the drip irrigation tape conduit is set to be flared.

[0016] Furthermore, the water dripping holes of the drip irrigation tape are laid downward in the groove.

[0017] Furthermore, a soil covering implement mounting frame is also provided on the large bracket. The soil covering implement is mounted on the soil covering implement mounting frame and a certain distance is reserved between the soil covering implement and the drip irrigation tape layer;

[0018] The soil covering implement is a rubber plate.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. The upper and lower crop compatibility shallow buried drip irrigation tape layer in the wheat and corn double-cropping area in one year. The wheat seeder adopts 40 cm or 45 cm ridge-free uniform sowing. After sowing, the drip irrigation tape is laid in the middle of 40 cm or 45 cm. The water and fertilizer in the range of 40 cm or 45 cm for wheat watering are concentratedly supplied. It saves about 40% of water and about 30% of fertilizer compared with the traditional shallow buried drip irrigation laying method.

[0021] 2. Reform of the next-season corn planting: Change the traditional 60-cm equal-row corn planting to wide-narrow row planting. The corn adopts a row spacing layout of 40 - 80 cm, and the drip irrigation tape for wheat is laid at 40 cm or 45 cm. After wheat harvesting, the summer corn planting is changed to wide-narrow row planting. For summer corn, one group of 80-cm water supply drip irrigation tapes is closed for water and fertilizer supply. The corn realizes concentrated water and fertilizer supply with a 40-cm narrow row spacing. An innovative shallow-buried drip irrigation tape laying mode for wheat and corn in the upper and lower seasons is achieved, with the integration of wheat and corn in the upper and lower seasons, saving water, labor, and fertilizer. Especially for summer corn, it ensures fertilizer supply in the middle and late stages compared with the traditional planting method, significantly increasing the corn yield per mu. The traditional watering method is changed. The rainy season from late July to early August is the critical period for corn fertilizer demand. Due to the inability of manual and mechanical operations to enter the field for fertilization of tall crops, the water and fertilizer irrigation method with drip irrigation tapes reserved in the trenches can significantly increase the wheat yield per mu by more than 10% and the corn yield per mu by more than 20%.

[0022] 3. On the press roller of the wheat seeder, a furrow opener with a designed height of 2.5 - 3 cm and a width of not less than 2 cm deep is designed. While pressing after sowing, a trench is pressed in the row. The drip irrigation tape is reserved in the trench, and finally covered with a soil covering device. In this way, during the sowing operation, the sowing and pressing operations are realized, and at the same time, the operation of laying the drip irrigation tape is completed, realizing the integrated operation of wheat sowing and tape laying, changing the traditional separate sowing and separate tape laying operation methods, improving efficiency, saving costs, and achieving the effect of dual use (for wheat and corn) with one laying.

[0023] 4. Laying the drip irrigation tape with the drip holes facing down has a good effect of creating a shady soil moisture, accelerating seed germination, and when watering and fertilizing plants in the future, it can make water and fertilizer better reach the roots of plants, promoting plant growth and increasing yield.
