TECHNICAL FIELD
[0001] The present application relates to the technical field of agricultural engineering, in particular to a wide-sowing furrow film mulching seeder film mulching ridging device for dry saline soil. BACKGROUND
[0002] The design of the dry farming agricultural machinery takes into account the characteristics of saline soil compaction and low fertility, and combines mechanical structure mechanics, agronomic adaptability design and other technologies. By optimizing the angle of the ridging knife and the film tension adjusting mechanism, the precise matching of the agricultural machinery and the agriculture is realized. It is a key equipment component for promoting the large-scale and mechanized planting of dry saline soil. The wide-sowing furrow film mulching seeder film mulching ridging device is a special agricultural machinery component that meets the requirements of dry saline soil planting. It integrates ridging, shaping, film mulching and edge pressing functions in one, and is mainly used for dry saline soil sowing operation.
[0003] For example, the application number CN202122340371.2 is a farmland plowing ridging and film mulching device, which includes a main frame, a rotary tiller and a ridging and film mulching mechanism. The rotary tiller and the ridging and film mulching mechanism are installed on the main frame in front and back respectively. The rotary tiller is welded with a damping device at the bottom of the main frame. The damping device includes a first support plate, a second support plate and a damping spring. The first support plate is fixedly connected with the second support plate through the damping spring. The frame of the ridging and film mulching mechanism is connected with the main frame. Two concave groove ridgers are connected to the rear side of the rotary tiller. A film mulching cylinder is arranged on the concave groove ridger. Two film pressing inner wheels are arranged at the middle position of the rear end of the frame. One film pressing outer wheel is arranged on each side of the rear end of the frame. The invention installs a damping device between the main frame and the mounting beam, which can reduce the vibration caused by the operation of the equipment and improve the damping effect. The rotary tiller is connected with the concave groove ridger behind it to form a smooth and flat ridge, realizing the mechanized operation of ridging and film mulching. However, the ridging depth of the film mulching ridging device cannot be adjusted, and it is easy to jam and stop. The split type operation ridge is easy to displace and has poor flatness.

A pressure roller 205 is provided on the outer surface of the adjusting rod 204, and a pressure roller 205 is installed on the outer surface of the adjusting rod 204. The ridging blade 206 has an anti-stick coating 207 fixedly connected to its outer surface. The connecting rod 201 provides stable installation support for the ridging and flattening mechanism 2. The screw 202 connected internally can precisely adjust the height of the mounting plate 203 to adapt to the ridging depth requirements of different soil conditions. The adjusting rod 204 on the mounting plate 203 simultaneously supports the pressure roller 205 and the ridging blade 206. The anti-stick coating 207 on the outer surface of the ridging blade 206 reduces soil adhesion and ensures that the ridge is formed in a regular manner. The pressure roller 205 flattens the soil after ridging in real time and improves the density of the ridge.
[0018] like Figure 4 As shown, the main adjusting frame 3 is sleeved inside the fixed frame 1, and the main adjusting frame 3 is threadedly connected to the fastening bolt 4. A connecting rod 5 is fixedly connected to one side of the fixed frame 1, and a side column 6 is fixedly connected to one side of the connecting rod 5. The main adjusting frame 3 is sleeved inside the fixed frame 1, and the position is precisely fixed by the threaded locking of the fastening bolt 4, which can adapt to the installation requirements of different working scenarios. The connecting rod 5 on one side of the fixed frame 1 provides rigid connection support for the side column 6. The side column 6 extends outward to widen the support range, enhance the overall structural stability, and at the same time provide an installation base point for subsequent auxiliary working parts, ensuring the stability of the whole machine during operation.
[0019] Furthermore, the main adjusting frame 3 is sleeved inside the fixed frame 1, and the main adjusting frame 3 is threadedly connected to the fastening bolt 4. A connecting rod 5 is fixedly connected to one side of the fixed frame 1, and a side column 6 is fixedly connected to one side of the connecting rod 5. The main adjusting frame 3 is sleeved inside the fixed frame 1, and the position is precisely fixed by the threaded locking of the fastening bolt 4, which can adapt to the installation requirements of different working scenarios. The connecting rod 5 on one side of the fixed frame 1 provides rigid connection support for the side column 6. The side column 6 extends outward to widen the support range, enhance the overall structural stability, and at the same time provide an installation base point for subsequent auxiliary working parts, ensuring the stability of the whole machine during operation.
[0020] Furthermore, a pull rod 7 is installed on one side of the side column 6, and a blade storage slot 8 is provided inside the side column 6. A triangular connecting frame 11 is fixedly connected to the top of the top column 9, and a connecting hole 12 is provided inside the triangular connecting frame 11. The pull rod 7 on one side of the side column 6 can flexibly adjust the extension length to adapt to different lengths of film.

The crusher 1002 achieves efficient cutting and crushing of straw, avoids straw entanglement with subsequent ridging components, and improves the smoothness of the whole machine operation.
[0022] Working Principle: When using the mulching and ridging device of this drought-resistant wheat wide-seedling micro-furrow mulching seeder, firstly, the main adjusting frame 3 is fitted inside the fixed frame 1, and the fastening bolts 4 are tightened to achieve precise positioning. The side column 6 is fixed by the connecting rod 5 on one side of the fixed frame 1 to widen the support range. Then, the extension length of the pull rod 7 on the side column 6 is adjusted to adapt to the mulching width requirements. At the same time, the sliding blade 1004 is stored in the blade storage groove 8. The device is connected to the tractor or other drive equipment through the connecting hole 12 of the triangular connecting frame 11 at the top of the top column 9. Then, the drive equipment drives the device to move forward. During the movement, the mulch is pulled, and the straw crushing mechanism 10 carried by the top column 9 starts the crusher 1002 to chop the straw in the field. At the same time, the screw 2 of the ridging and flattening mechanism 2 is adjusted. 02. The height of the mounting plate 203 is adjusted by the connecting rod 201. The adjusting rod 204 on the mounting plate 203 simultaneously drives the ridging blade 206 into the soil to form ridges. The anti-stick coating 207 prevents soil from sticking and ensures that the ridges are neat. Finally, the ridges are flattened and the mulching is prepared. The pressure roller 205 flattens the soil after ridging in real time to improve the density of the ridges. After the wheat seedlings are covered with mulch, the sliding blade 1004 in the blade groove 1003 is pulled out according to the operation requirements to cut the mulch. This is the working principle of the mulching and ridging device of the drought-resistant and alkaline wheat wide seedling micro-furrow mulching seeder.
