Multiple strip-shaped scraper slots 703, which are equal in number to the number of the plowing components, are vertically opened through the bottom surface of the scraper seat 701. The width of the strip-shaped scraper slots 703 is equal to twice the width of the plowing claws 602. In the top view direction, each plowing claw 602 is located in one of the strip-shaped scraper slots 703.

[0062] Working principle:

[0063] When the user pushes the planting device forward using the handle 301

[0064] First, several bulbs of Fritillaria cirrhosa are placed into the planting cavity 201 located at the rear. The hydraulic telescopic rod 103 is activated, causing the swing rod 105 to swing downwards. This causes the entire second rotating shaft 601, plowing claw 602, and first motor 801 to move downwards as a whole, until a portion of the plowing claw 602 enters the ground (the depth to which a portion of the claw needs to enter the ground is determined based on the actual situation). Then, the first motor 801 is activated, and the second rotating shaft 601 rotates, thereby driving the plowing claw 602 to rotate and plow the ground until depressions appear between the planting rows. Finally, the second motor 801 is activated. 2 (the second motor 802 arranged on the rear side) causes the first rotating shaft 502 to rotate, thereby causing the planting guide plate 501 to rotate synchronously. During this process, multiple Fritillaria bulbs located in the planting insertion cavity 201 continuously fall into each planting guide groove 503 that is rotated to the highest position. After the Fritillaria bulbs located in the planting guide groove 503 are rotated and moved to the lowest position of the first rotating shaft 502, they fall out from the planting guide groove 503 at the lowest position and enter the outlet channel 203. Then, multiple Fritillaria bulbs are dispersed through the diversion channel and fall into the planting rows.

[0065] When the planting device is in a position where it cannot turn around, the user can pull the planting device backward to plant. During this process, several Fritillaria bulbs are placed into the planting cavity 201 set at the front. The hydraulic telescopic rod 103 is activated, causing the swing rod 105 to swing downward, thereby causing the entire second rotating shaft 601, plowing claw 602, and first motor 801 to move downward as a whole until part of the plowing claw 602 enters the ground. Then, the first motor 801 is activated, and the second rotating shaft 601 rotates, thereby driving the plowing claw 602 to rotate and plow the ground until the ground has depressions between the planting rows. Then, the second motor 802 (the second motor arranged at the front) is activated. 802), causing the first rotating shaft 502 to rotate, thereby causing the planting guide plate 501 to rotate synchronously. During this process, multiple Fritillaria bulbs located in the planting insertion cavity 201 continuously fall into each planting guide groove 503 at the highest position. After the Fritillaria bulbs located in the planting guide groove 503 are rotated and moved to the lowest position of the first rotating shaft 502, they fall out from the planting guide groove 503 at the lowest position and enter the outlet channel 203. Then, multiple Fritillaria bulbs are dispersed through the diversion channel (the design of the diversion surface 4032 allows the Fritillaria bulbs to be further guided and dispersed better) and fall into the planting rows.

[0066] When planting is complete, the hydraulic telescopic rod 103 is activated again, causing the swing rod 105 to swing upward, thereby causing the entire second rotating shaft 601, plowing claw 602 and first motor 801 to move upward as a whole, so as to avoid damaging the plowing claw 602.

[0067] In addition, each time the second rotating shaft 601 rotates, the synchronously rotating plowing claw 602 enters the strip-shaped scraper slot 703. Excess soil adhering to the plowing claw 602 is removed (scraped) by the strip-shaped scraper slot 703, ensuring that the plowing claw 602 plows the land more effectively to form planting rows. If the soil removed (scraped) from the plowing claw 602 is carried to the top surface of the scraper seat 701, it will roll off due to the design of the inclined surface 702, preventing excessive soil accumulation on the top surface of the scraper seat 701.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
