In order to better understand the technical means of the embodiments of this application and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of this application more obvious and understandable, specific implementation methods of this application are described below.

[0012] 1. By setting up crushing rollers, a first motor, a second motor, and crushing blades, soil is poured into the soil crushing box through the feeding pipe. Then, the crushing rollers perform initial crushing of the soil, and the soil falls into the positioning chamber through the discharge port. The second motor is started, which drives the positioning cylinder to rotate, thereby driving the crushing blades to rotate, so as to further crush the soil clods and improve the soil crushing effect.

[0013] 2. With the configuration of the first sealing cover, first bolt, second sealing cover, third bolt, second bolt, and limit cover, when the crushing roller needs to be replaced, unscrew the first bolt, remove the first sealing cover, then pull out the crushing roller, place the new crushing roller on the output shaft of the first motor, and make the limit block lock in the limit groove. Then, replace the first sealing cover and tighten the first bolt. When the crushing blade needs to be replaced, unscrew the third bolt, remove the second sealing cover, then unscrew the second bolt, lift the rectangular rod upwards until the rectangular rod is disengaged from the positioning cylinder, and then remove the crushing blade. Insert the rectangular rod on the new crushing blade into the positioning cylinder, and make the limit cover fit on the positioning cylinder. Then, tighten the second bolt again and reinstall the second sealing cover on the positioning chamber to complete the replacement of the crushing blade, thereby extending the service life of the device.

For example, "connection" or "linkage" in mechanical structures can refer to a physical connection, such as a fixed connection, a detachable connection, or an integral connection. In addition to referring to a physical connection, "connection" or "linkage" in circuit structures can also refer to an electrical connection or a signal connection. For example, it can be a direct connection, i.e., a physical connection, or an indirect connection through at least one intermediate component, as long as the circuit is connected. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0028] This application provides an auxiliary soil-crushing mechanism for agricultural sowing, including a positioning chamber 1. A soil-crushing box 2 is fixedly connected to the top of the positioning chamber 1, and a feeding pipe 3 is fixedly connected to the top of the soil-crushing box 2. A pair of first motors 4 are fixedly connected to the rear side wall of the soil-crushing box 2. The output shafts of the pair of first motors 4 pass through the side wall of the soil-crushing box 2. A crushing roller 5 is sleeved on the output shaft of the first motor 4. A pair of limiting grooves 6 are opened in the crushing roller 5. A limiting block 7 is set in the limiting groove 6. The limiting block 7 is fixedly connected to the output shaft of the first motor 4. A first sealing cover 8 is provided on the front side of the soil-crushing box 2. Two pairs of first bolts 9 pass through the first sealing cover 8. A threaded groove matching the first bolts 9 is opened on the front side wall of the soil-crushing box 2. A circular groove 10 is opened at the bottom of the positioning chamber 1, and a crushing mechanism is provided inside the positioning chamber 1. A discharge port 11 is opened between the top of the soil-crushing box 2 and the top of the positioning chamber 1.

[0029] In the technical solution of this application embodiment, the soil can be further crushed by the crushing mechanism. A pair of discharge pipes 12 are fixedly connected to the bottom of the positioning chamber 1. A valve is installed on the discharge pipe 12. The crushing mechanism includes a second motor 13, which is fixedly connected to the bottom of the positioning chamber 1. The output shaft of the second motor 13 passes through the positioning chamber 1 and is fixedly connected to a positioning cylinder 14. A limiting cover 15 is sleeved on the positioning cylinder 14. A rectangular rod 16 is fixedly connected to the limiting cover 15. The bottom end of the rectangular rod 16 extends into the positioning cylinder 14. Several crushing blades 17 are fixedly connected to the rod of the rectangular rod 16. Several second bolts 18 pass through the limiting cover 15. A threaded groove matching the second bolts 18 is opened on the top of the positioning cylinder 14.

[0030] In the technical solution of this application embodiment, the crusher blade 17 can be easily replaced by the second sealing cover 19 and the third bolt 20. The front side of the positioning chamber 1 is provided with the second sealing cover 19, and two pairs of third bolts 20 pass through the second sealing cover 19. The front side wall of the positioning chamber 1 is provided with a threaded groove that matches the third bolt 20. A pair of L-shaped plates 21 are fixedly connected to the bottom of the positioning chamber 1. A pair of rollers 22 are fixedly connected to the bottom of the pair of L-shaped plates 21. The pair of L-shaped plates 21 are symmetrically arranged about the central axis of the positioning chamber 1, and the two pairs of rollers 22 are symmetrically arranged about the central axis of the L-shaped plates 21.

[0031] Working principle: In use, the first motor 4 is started, driving the crushing roller 5 to rotate. Soil is then poured into the soil crushing box 2 through the feeding pipe 3. The crushing roller 5 performs initial crushing of the soil, which then falls into the positioning chamber 1 through the discharge port 11. Next, the second motor 13 is started, driving the positioning cylinder 14 to rotate, which in turn drives the crushing blade 17 to rotate, further crushing the soil clods until the soil crushing is complete. Then, the valve of the discharge pipe 12 is opened, and the soil is discharged through the discharge pipe 12. When the crushing roller 5 needs to be replaced, the first bolt 9 is unscrewed, the first sealing cover 8 is removed, and then the crushing roller 5 is pulled out to install the new crushing roller. The first sealing cover 8 is then replaced and the first bolt 9 is tightened. When the crushing blade 17 needs to be replaced, the third bolt 20 is unscrewed, the second sealing cover 19 is removed, and then the second bolt 18 is unscrewed. The rectangular rod 16 is then lifted until it is disengaged from the positioning cylinder 14, at which point the crushing blade 17 can be removed. The rectangular rod 16 on the new crushing blade 17 is inserted into the positioning cylinder 14, and the limiting cover 15 is fitted onto the positioning cylinder 14. Then the second bolt 18 is tightened again, and the second sealing cover 19 is reinstalled on the positioning chamber 1, thus completing the replacement of the crushing blade 17.
