[0002] In order to ensure the timeliness of sowing after the wheat harvest is completed, it is necessary to sow crops such as corn immediately without performing steps such as rotary tillage in the middle. Therefore, the seeder needs to sow in a no-till environment. In terms of irrigation, drip irrigation, compared with the previous furrow irrigation and flooding irrigation methods, not only has the advantages of saving irrigation costs and improving irrigation accuracy, but also can complete the task of adding fertilizers in the later stage. Therefore, drip irrigation has become the first choice of most farmers.

[0003] The shallow buried devices of drip irrigation tapes currently available on the market have a small up and down floating stroke. Due to the uneven conditions in the farmland, the trenching depth is often inconsistent when trenching, which makes the buried depth of the drip irrigation tape inconsistent, thus affecting the subsequent irrigation accuracy.

DETAILED DESCRIPTION

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0026] like Figure 1-3 As shown, the utility model provides a shallow buried device for drip irrigation tape for no-till seeding, comprising a connecting frame 1, the rear end of the connecting frame 1 is installed on a tractor, the front end of the connecting frame 1 is horizontally provided with a drip irrigation tape beam 2, the upper end of the drip irrigation tape beam 2 is provided with a drip irrigation tape placement tray 4, and the drip irrigation tape placement tray 4 is wound with a drip irrigation tape.

[0027] A shoe-type furrow opener is installed at the lower end of the beam 2, and the shoe-type furrow opener is installed on the beam 2 through a four-bar linkage so as to be movable up and down.

[0028] Two support rods 3 are fixedly arranged at the upper end of the beam 2. The two support rods 3 are arranged obliquely upward. A drip irrigation belt placement plate 4 is rotatably installed at the top between the two support rods 3. Figure 2 As shown, a limit bolt 5 is inserted at the top of the support rod 3, and the limit bolt 5 can ensure that the drip irrigation tape will not fall off due to the shaft of the drip irrigation tape placement plate 4 coming out during operation.

[0029] The four-bar linkage includes a furrow opener mounting frame 9, an upper connecting rod 7, a lower connecting rod 10 and a fixing frame 6. The fixing frame 6 is fixedly mounted on the front side of the beam 2. The furrow opener mounting frame 9 is connected to a boot-type furrow opener. The furrow opener mounting frame 9 is arranged parallel to the fixing frame 6. The upper connecting rod 7 and the lower connecting rod 10 are hinged at the upper and lower ends of the furrow opener mounting frame 9 and the fixing frame 6, respectively.

[0030] A tension spring 8 is provided between the upper connecting rod 7 and the lower connecting rod 10. The tension spring 8 pulls the furrow opener mounting frame 9 to move downward, which can ensure that the shoe-type furrow opener provides continuous and stable ground pressure during operation, so that the furrowing depth is consistent, thereby ensuring the consistent burial depth of the drip irrigation tape.

[0031] The boot-type furrow opener includes a furrowing frame 11, which is installed on a furrowing opener mounting frame 9. A boot gripper 14 is provided on the front side of the lower end of the furrowing frame 11. The boot gripper 14 is a casting to ensure working strength. The upper surface of the boot gripper 14 forms an angle of 3° with its horizontal bottom surface to ensure that the front tip of the boot gripper 14 enters the soil first when entering the soil, which can effectively reduce the furrowing resistance.

[0032] A stubble cleaning roller 13 is rotatably installed at a position above the ditching frame 11 and the boot tightener 14. A thimble bolt 12 is provided on the top of the stubble cleaning roller 13, and a socket is provided in the middle position of the top of the stubble cleaning roller 13. The thimble bolt 12 is inserted into the socket of the stubble cleaning roller 13 to limit the position of the stubble cleaning roller 13 and facilitate the disassembly and replacement of the stubble cleaning roller 13.

[0033] A drip irrigation belt guide wheel 19 is provided at the rear side of the lower end of the ditching frame 11. After the shoe toughener 14 digs the ditch, the drip irrigation belt is buried in the ditch under the guidance of the drip irrigation belt guide wheel 19.

[0034] A soil covering device is provided at the rear side of the lower end of the trenching frame 11. The soil covering device is provided at the rear side of the drip irrigation belt guide wheel 19. The soil covering device includes two soil covering plates 17 arranged vertically relative to each other. Figure 3 As shown, the soil covering plate 17 buries the drip irrigation belt in the ditch.

[0035] The soil covering device also includes a soil covering pressure plate 16, which is installed on the front side of the soil covering disc 17. A pressure spring 15 is installed on the upper side of the soil covering pressure plate 16. The pressure spring 8 can ensure that the soil covering plate 16 provides ground pressure during the soil covering process, so as to achieve a uniform soil covering effect.

[0036] The specific working principle of the utility model:

[0037] During operation, the boot-type furrow opener performs furrowing operations at the front end of the furrowing frame 11. After furrowing, the drip irrigation tape is buried in the furrow along the drip irrigation tape guide wheel 19, and the covering plate 17 buries the drip irrigation tape in the furrow. The pressure spring 8 can ensure that the covering plate 16 provides ground pressure during the covering process, so as to achieve a uniform covering effect; the tension spring 8 pulls the furrow opener mounting frame 9 to move downward, which can ensure that the boot-type furrow opener provides continuous and stable ground pressure during operation, so that the furrowing depth is consistent, thereby ensuring the consistent burial depth of the drip irrigation tape.

[0038] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field.
