[0039] In one embodiment, the support frame 700 is composed of two L-shaped support rods 710, and the second drive mechanism 210 extends from between the two support rods 710 and is placed under the two support rods 710, which effectively reduces the assembly volume of the device of the present invention, has a compact structure, and is more conducive to transporting the device of the present invention to mountainous areas, hills, and the like.

[0040] The support frame 700 is provided with two support plates 720, and the rotary tiller 220 includes a rotating shaft 221 and a rotary tiller blade 222 provided on the rotating shaft 221. The rotating shaft 221 is clamped between the two support plates 720 by a bearing, and the second driving mechanism 210 extends from the rear side of the frame body 500 to the bottom of the support frame 700 and is connected to the middle of the rotating shaft 221. The rotary tiller 220 is evenly distributed on both sides of the second driving mechanism 210 to effectively ensure the balance of force on the rotating shaft 221 when the rotary tiller 220 performs rotary tillage and loosening operations on the ground; the second driving mechanism 210 drives the rotating shaft 221 to rotate, thereby causing the rotary tiller blade 222 to rotate synchronously, thereby achieving the effect of leveling and loosening the ground; a rotary tiller seat 223 is provided on the rotating shaft 221, and the rotary tiller seat 223 is fixed to the rotating shaft 221 by a screw sleeve and rotates together with the rotating shaft 221. The outer surface of the rotary tillage seat 223 is staggered with multiple slots 224, and the rotary tillage blade 222 is placed in the slot 224, so that the loosening area of ​​the rotary tiller 220 is larger and the efficiency is higher; the rotary tillage blade 222 is a 7-shaped blade structure, and the rotary tillage blade 222 includes a main body 2221 and a blade tip 2222. The main body 2221 is placed in the slot 224, and the angle between the main body 2221 and the blade tip 2222 is 120°~140°. Preferably, the angle between the main body 2221 and the blade tip 2222 is 130°, which can reduce the probability of straw or stalks blocking the rotary tillage blade 222 while ensuring a good rotary tillage effect of the rotary tillage mechanism 200.

[0041] The punching mechanism 300 includes a third driving mechanism 310 and a puncher 320. The third driving mechanism 310 is connected to the puncher 320. The third driving mechanism 310 is arranged on one side of the fertilizing mechanism 400. The third driving mechanism 310 drives the puncher 320 to move up and down. When the power mechanism 100 drives the punching mechanism 300 and the rotary tillage mechanism 200 to move, the puncher 320 will push the soil loosened by the rotary tillage mechanism 200 toward both sides of the puncher 320, and cooperate with the third driving mechanism 310 to drive the puncher 320 to move up and down, so that a plurality of hole positions 600 are formed at intervals on the ground in the moving direction of the rotary tillage mechanism 200.

[0042] The punching mechanism 300 also includes a fixing frame 330, which is arranged on one side of the fertilizing mechanism 400 and connected to the support frame 700. The third driving mechanism 310 is arranged on the fixing frame 330, and the puncher 320 is provided with a soil retaining plate 321. When the first driving mechanism 110 drives the driving wheel 120 to move, the rotary tillage mechanism 200 and the punching mechanism 300 also move along with the driving wheel 120 in the direction of travel of the driving wheel 120. The rotary tillage mechanism 200 performs a ground leveling and loosening operation on the ground in its direction of travel. During the advancement process, the soil retaining plate 321 will guide the soil loosened by the rotary tillage mechanism 200, so that the soil loosened by the rotary tillage mechanism 200 is pushed toward both sides of the soil retaining plate 321, and cooperate with the third driving mechanism 310 to drive the soil retaining plate 321 to perform up and down reciprocating motion, so that a plurality of hole positions 600 are formed at intervals on the ground in the direction of travel of the rotary tillage mechanism 200.

[0043] The puncher 320 also includes a fixing seat 322, and the retaining plate 321 is arranged on one side of the fixing seat 322. Specifically, the retaining plate 321 is arranged on the front side of the fixing seat 322 to guide the soil loosened by the rotary tillage mechanism 200 to both sides of the fixing seat 322. The fixing seat 322 is a hollow structure to facilitate the fertilizer in the fertilizing mechanism 400 to pass through the fixing seat 322 and fall into the hole 600 formed by the retaining plate 321 pushing the soil loosened by the rotary tillage mechanism 200; the cross-section of the retaining plate 321 is a V-shaped structure to reduce the rotation of the tillage mechanism. The soil loosened by the mechanism 200 provides resistance to the puncher 320. In this embodiment, the width of the retaining plate 321 is 20 cm to prevent the soil in the hole 600 from falling too quickly. The length of the retaining plate 321 is 20 cm to facilitate the control of the depth of the hole 600, so as to prevent the hole 600 from being too deep and causing the soil to accumulate higher and fall into the fixing seat 322, thereby affecting the normal fertilization operation of the fertilizing mechanism 400. In other embodiments, the retaining plate 321 can also be set as a straight plate or an arc plate structure.

[0044] In one embodiment, the bottom end face of the puncher 320 is a beveled surface structure. Specifically, the bottom end faces of the fixing seat 322 and the retaining plate 321 are both beveled surface structures. During the punching operation of the punching mechanism 300, the bottom end portions of the fixing seat 322 and the retaining plate 321 are tangent to the shape of the hole position 400 formed on the ground to avoid the fixing seat 322 and the retaining plate 321 interfering with the formation of the hole position 400 and affecting the molding quality of the hole position 400.

[0045] The third driving mechanism 310 includes a driving motor 311, a driving disk 312, a crank 313, a slide rail 314 and a slide rod 315. The driving motor 311 is arranged on the fixed frame 330, and the driving motor 311 is connected to the driving disk 312. The driving motor 311 drives the driving disk 312 to rotate. One end of the crank 313 is arranged at the edge of the driving disk 312, and the other end of the crank 313 is connected to the slide rod 315. One end of the slide rod 315 is connected to the punch 320. The slide rod 315 is clamped on the slide rail 314, and the slide rod 315 moves along the slide rail. 314 direction; specifically, the driving motor 311 drives the driving disk 312 to rotate, and then the crank 313 also rotates with the driving disk 312, and then drives the slide bar 315 to slide back and forth along the slide rail 314. Since the puncher 320 is connected to the slide bar 315, the puncher 320 slides back and forth along the slide rail 314. The puncher 320 moves behind the rotary tillage mechanism 200 while moving up and down along the slide rail, so that the puncher 320 performs a hole drilling operation 600 on the ground in the direction of travel of the rotary tillage mechanism 200.

[0046] Specifically, the slide rail 314 is fixed on the fertilizing mechanism 400, and the slide rod 315 is clamped on the slide rail 314 through a limiting mechanism. In this embodiment, the limiting mechanism includes a limiting protrusion 3141 arranged on the slide rail 314 and a limiting slot 3151 clamped on the slide rod 315. The limiting protrusion 3141 is clamped in the limiting slot 3151 to prevent the slide rod 315 from detaching from the slide rail 314 and affecting the quality of use of the punching mechanism 300.

[0047] In other embodiments, alternatively, the limiting mechanism includes a limiting protrusion 3141 provided on the slide rod 315 and a limiting slot 3151 provided on the slide rail 314; or as needed, a slide slot may be provided on the slide rail 314 or the slide rod 315 to achieve the docking engagement between the slide rail 314 and the slide rod 315, thereby avoiding the slide rod 315 and the slide rail 314 from separating from each other, causing quality problems in the use of the punching mechanism 300.

[0048] In one embodiment, the puncher 320 is fixedly connected to the slide rod 315 by screws. Since the up and down movement displacement of the slide rod 315 of the third driving mechanism 310 remains unchanged, the punching depth of the puncher 320 is adjusted by adjusting the fixed position of the puncher 320 on the slide rod 315, thereby meeting the different needs of tobacco leaf planting and punching.

[0049] The fertilizing mechanism 400 includes a fertilizer box 410 and an adjusting mechanism 420. The fertilizer box 410 is arranged at the rear end of the support frame 700, and the adjusting mechanism 420 is arranged at the bottom end of the fertilizer box 410. The fertilizer box 410 is used to store fertilizer. The adjusting mechanism 420 is connected to the fertilizer box 410. The adjusting mechanism 420 is used to transport the fertilizer in the fertilizer box 410 to the hole 600 punched by the punching mechanism 300, further improving the compactness of the structure of the device of the present invention.

[0050] The regulating mechanism 420 is used to pre-store fertilizer to control the amount of fertilizer falling from the fertilizer box 410. The regulating mechanism 420 is arranged above the puncher 320; the regulating mechanism 420 is provided with an inlet 401 and an outlet 402. The inlet 401 is connected to the fertilizer box 410, and the outlet 402 is arranged above the puncher 320. The pre-stored fertilizer falling from the outlet 402 in the regulating mechanism 420 passes through the puncher 320 and falls into the hole position 600, realizing the synchronous operation of rotary tillage, punching and fertilizing, ensuring construction quality, effectively improving construction efficiency and reducing labor intensity.

[0051] The regulating mechanism 420 includes a feeding shell 421, the feeding shell 421 is arranged on one side of the support frame 700, the slide rail 314 is fixedly arranged on one side of the feeding shell 421, a movable plate 422 is arranged in the feeding shell 421, the movable plate 422 separates the feeding shell 421 into a movable bin 403 and a storage bin 404, the pre-stored fertilizer is placed in the storage bin 404, in the initial state, the feed port 401 is matched and arranged at the top of the storage bin 404, and the discharge port 402 is matched and arranged at the bottom of the movable bin 403; a pushing component 423 is provided on one side of the movable plate 422, and the pushing component 423 is provided on the other side of the movable plate 422. The component 423 can be movably arranged in the feeding shell 421, and the storage bin 404 is formed by the pushing component 423, the movable plate 422 and the feeding shell 421; the pushing component 423 can move back and forth in the feeding shell 421 under the drive of an external driving device. When the pushing component 423 drives the movable plate 422 to move in the feeding shell 421, the pre-stored fertilizer in the storage bin 404 also moves with the movable plate 422, and then the pre-stored fertilizer in the storage bin 404 is pushed to the discharge port 402, and falls into the hole 600 punched by the puncher 320 to realize fertilization operation.

[0052] Specifically, the fertilizer in the fertilizer box 410 enters the storage bin 404 through the feed port 401. There is a movable plate 422 between the storage bin 404 and the movable bin 403. The movable plate 422 serves to isolate the movable bin 403 from the storage bin 404. When the pushing assembly 423 moves to the left, since the pushing assembly 423 is connected to the movable plate 422, the pushing assembly 423 will push the movable plate 422 to move to the left to the discharge port 402. A gap is formed between the pushing assembly 423 and the discharge port 402. Under the action of gravity, the pushed assembly 423 is pushed to the left. The fertilizer in the storage bin 404 pushed by the component 423 will flow out from the gap between the pushing component 423 and the discharge port 402, and fall from the discharge port 402 into the hole 600 punched by the puncher 320, thereby realizing the fertilization operation; in addition, the amount of fertilization is controlled by setting the capacity of the storage bin 404 or controlling the amount of fertilizer falling into the storage bin 404, thereby ensuring that the amount of fertilization is controllable and the fertilization effect is uniform; in this embodiment, the pushing component 423 can be controlled by an external driving device to complete the movement operation of the pushing component 423 in the feeding shell 421.

[0053] In one embodiment, the pushing component 423 is provided with a baffle plate 4231 on one side of the opening 4041 above the storage bin 404. When the pushing component 423 is in the initial position, the opening 4041 above the storage bin 404 is connected to the feed port 401, and fertilizer can fall into the storage bin 404 from the feed port 401; when the pushing component 423 drives the movable plate 422 to move to the preset position to the left, the baffle plate 4231 of the pushing component 423 closes the feed port 401 to prevent the fertilizer from continuously flowing into the storage bin 404 from the feed port 401; specifically, the storage bin 404 The area of ​​the opening 4041 can be larger than the area of ​​the feed port 401 to ensure that the fertilizer falling from the feed port 401 falls completely into the storage bin 404. When the movable plate 422 is about to move to the position of the discharge port 402, the baffle plate 4231 of the pushing component 423 closes the feed port 401 to ensure that no additional fertilizer flows from the feed port 401 into the storage bin 404 before the adjusting mechanism 420 discharges the material. Then the pushing component 423 continues to drive the movable plate 422 to move to the left until all the fertilizer flows out from the gap between the movable plate 422 and the discharge port 402 to realize the fertilization operation.

[0054] In one embodiment, the pushing assembly 423 further includes a push rod 4232 and a movable block 4233 connected to the push rod 4232. The position of the movable block 4233 in the storage bin 404 is adjusted by moving the push rod 4232 to control the storage volume of the storage bin 404, thereby controlling the single fertilizer application amount of the fertilizing mechanism 400, ensuring that the fertilizer application amount can be adjusted to meet the fertilizer requirements of different tobacco plantings; the push rod 4232 is a screw rod structure, and the push rod 4232 is arranged to pass through one side of the pushing assembly 423. Specifically, the pushing assembly 423 is A mounting hole (not shown) is provided on the side, and the push rod 4232 is provided through the mounting hole. The push rod 4232 is threadedly connected to the mounting hole. The push rod 4232 can be connected to the movable block 4233 by a bearing connection to ensure that when the push rod 4232 moves to the left or right along its own central axis, the movable block 4233 also moves to the left or right synchronously, thereby realizing the adjustment of the storage volume of the storage bin 404, thereby controlling the single fertilizer application amount of the fertilizing mechanism 400, and ensuring that the fertilizer application amount can be adjusted to meet the fertilizer requirements of different tobacco plantings.
