[0044] When the rotary tillage mechanism 200 moves, the punching mechanism 300 and the fertilizing mechanism 400 move together with the rotary tillage mechanism 200. The puncher 320 is used to push the soil loosened by the rotary tillage mechanism 200 toward both sides of the puncher 320, and cooperates with the first driving mechanism 310 to drive the puncher 320 to do up and down reciprocating motion, so that a plurality of hole positions 500 are formed at intervals on the ground in the moving direction of the rotary tillage mechanism 200; wherein, each time the puncher 320 performs an up and down reciprocating motion, the fertilizing mechanism 400 synchronously performs a fertilizing operation.

[0046] The rotary tillage mechanism 200, the punching mechanism 300 and the fertilizing mechanism 400 are all arranged on the power mechanism 100, and the power mechanism 100 drives the rotary tillage mechanism 200, the punching mechanism 300 and the fertilizing mechanism 400 to move; 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 to both sides, and cooperate with the first driving mechanism 310 to drive the puncher 320 to do up and down reciprocating motion, so that a plurality of hole positions 500 are formed at intervals on the ground in the moving direction of the rotary tillage mechanism 200.

[0047] In this embodiment, the power mechanism 100 is separately arranged from the rotary tillage mechanism 200, and the power mechanism 100 includes a frame 110, on which a second driving mechanism 120 is arranged, and driving wheels 130 are respectively arranged on both sides of the frame 110, and the second driving mechanism 120 is used to drive the driving wheel 130 to move along the direction of travel; in this embodiment, the wheel diameter of the driving wheel 130 is 68mm and the wheelbase is 100mm, so as to ensure that the driving wheel 130 is in the grooves on both sides of the ridge to facilitate the driving wheel 130 to move along the groove direction, and also to ensure that the frame 110 is above the ridge to avoid the bottom of the frame 110 scratching the soil on the ridge and affecting the ridge-forming quality.

[0048] The rotary tillage mechanism 200 includes a support frame 210, a rotary tiller 220 and a third driving mechanism 230. The support frame 210 is fixedly arranged on one side of the power mechanism 100, and the fertilization mechanism 400 is fixedly arranged on one side of the support frame 210. Specifically, the support frame 210 is fixedly arranged on one side of the frame body 110, and the rotary tiller 220 is arranged on the support frame 210. The third driving mechanism 230 is connected to the rotary tiller 220, and the third driving mechanism 230 drives the rotary tiller 220 to operate, thereby performing rotary tillage operations on the ground.

[0049] Specifically, the rotary tiller 220 includes a rotating shaft 221 and a rotary tiller blade 222 arranged on the rotating shaft 221, the rotating shaft 221 is clamped and arranged on the support frame 210, the third driving mechanism 230 is connected to the rotating shaft 221, the third driving mechanism 230 drives the rotating shaft 221 to rotate, and then the rotary tiller blade 222 rotates synchronously, so as to achieve the effect of loosening the ground; a rotary tiller seat 223 is arranged on the rotating shaft 221, the rotary tiller seat 223 is fixed on the rotating shaft 221 by a screw sleeve, and rotates together with the rotating shaft 221, and the outer surface of the rotary tiller seat 223 is staggered at intervals. There are multiple slots 224, and the rotary tiller 222 is placed in the slots 224, so that the loosening area of ​​the rotary tiller 220 is larger and the efficiency is higher; the rotary tiller 222 is a 7-shaped knife structure, and the rotary tiller 222 includes a main body 2221 and a blade tip 2222, and the main body 2221 is placed in the slots 224. 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 the rotary tiller 222 being blocked by straw or stalks while ensuring a good rotary tillage effect of the rotary tillage mechanism 200.

[0050] In this embodiment, the third driving mechanism 230 is fixedly arranged on one side of the frame 110, and two support plates 211 are arranged on the support frame 210. The rotating shaft 221 is clamped between the two support plates 211 through a bearing. The third driving mechanism 230 extends from one side of the frame 110 to the bottom of the support frame 210 and is connected to the middle part of the rotating shaft 221. The rotary tiller 220 is evenly distributed on both sides of the third driving mechanism 230 to effectively ensure the balance of force on the rotating shaft 221 when the rotary tiller 220 loosens the ground.

[0051] The punching mechanism 300 also includes a fixing frame 330, and the fixing frame 330 is arranged on one side of the fertilizing mechanism 400. The first driving mechanism 310 is arranged on the fixing frame 330. The puncher 320 is provided with a retaining plate 321. When the rotary tillage mechanism 200 performs soil leveling and loosening operations on the ground in its moving direction, the 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 retaining plate 321, and cooperates with the first driving mechanism 310 to drive the retaining plate 321 to do up and down reciprocating motion, so that a plurality of hole positions 500 are formed at intervals on the ground in the moving direction of the rotary tillage mechanism 200.

[0052] The punch 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 the two 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 500 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 rotary tillage. 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 500 from falling too quickly, and the length of the retaining plate 321 is 20 cm to facilitate the control of the depth of the hole 500, so as to prevent the soil from piling up too high and falling into the fixing seat 322 due to the hole 500 being too deep, thereby affecting the normal fertilization operation of the fertilization mechanism 400. In other embodiments, alternatively, the retaining plate 321 can also be set as a straight plate or an arc plate structure.

[0053] In one embodiment, the bottom end surface of the puncher 320 is a beveled surface structure. Specifically, the bottom end surfaces 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 ends of the fixing seat 322 and the retaining plate 321 are tangent to the shape of the hole 500 formed on the ground to avoid the fixing seat 322 and the retaining plate 321 interfering with the formation of the hole 500 and affecting the molding quality of the hole 500.

[0054] The first driving mechanism 310 includes a driving motor 311, a driving disk 312, a crank 313, a slide rail 314 and a slide bar 315. The driving motor 311 is arranged on the fixing frame 330, 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, the other end of the crank 313 is connected to the slide bar 315, one end of the slide bar 315 is connected to the punch 320, the slide bar 315 is clamped on the slide rail 314, and the slide bar 315 moves along the slide rail 31 4 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 314, so that the puncher 320 performs a hole drilling operation 500 on the ground in the moving direction of the rotary tillage mechanism 200.

[0055] 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 use quality of the punching mechanism 300.

[0056] In other embodiments, alternatively, the limiting mechanism includes a limiting protrusion 3141 arranged on the sliding rod 315 and a limiting slot 3151 opened on the sliding rail 314; or as needed, a sliding slot can be opened on the sliding rail 314 or the sliding rod 315 to achieve the docking engagement between the sliding rail 314 and the sliding rod 315, so as to avoid the sliding rod 315 and the sliding rail 314 from detaching from each other, which may cause quality problems in the use of the punching mechanism 300.

[0057] 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 first 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 different needs of tobacco leaf planting and punching.

[0058] The fertilizing mechanism 400 is matched with the punching mechanism 300, and the fertilizing mechanism 400 includes a fertilizer box 410 and an adjusting mechanism 420. The fertilizer box 410 is used to store fertilizers, and the adjusting mechanism 420 is connected to the fertilizer box 410. The adjusting mechanism 420 is used to pre-store fertilizers to control the amount of fertilizer falling from the fertilizer box 410, and the adjusting mechanism 420 is arranged above the puncher 320; the adjusting mechanism 420 is provided with an inlet 401 and an outlet 402, and the inlet 401 is connected to the fertilizer box 410, and the outlet 402 is arranged above the puncher 320. The pre-stored fertilizer in the adjusting mechanism 420 that falls from the outlet 402 passes through the puncher 320 and falls into the hole position 500, thereby realizing the synchronous operation of mechanized punching and fertilization, reducing labor intensity, effectively ensuring the uniformity of fertilization, and meeting the needs of tobacco planting.

[0059] The regulating mechanism 420 includes a feeding shell 421, which is arranged on the support frame 210, and 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, and 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 assembly 423 is arranged on one side of the movable plate 422, and the pushing assembly Part 423 is 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 driven by 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 500 punched by the puncher 320, so as to realize the fertilization operation.

[0060] Specifically, the fertilizer in the fertilizer box 410 enters the storage bin 404 through the feed inlet 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 component 423 moves to the left, since the pushing component 423 is connected to the movable plate 422, the pushing component 423 will push the movable plate 422 to move to the left to the discharge port 402, and a gap will be formed between the pushing component 423 and the discharge port 402. Under the action of gravity, the pushed component The fertilizer in the storage bin 404 pushed by 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 500 punched by the puncher 320, thereby realizing the fertilization operation; in addition, the fertilization amount 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 the controllable fertilization amount and uniform fertilization effect; 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.

[0061] 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 inlet 401, and fertilizer can fall into the storage bin 404 from the feed inlet 401; when the pushing component 423 drives the movable plate 422 to move to the left to a preset position, the baffle plate 4231 of the pushing component 423 closes the feed inlet 401 to prevent the fertilizer from continuously flowing into the storage bin 404 from the feed inlet 401; specifically, the storage bin 404 The area of ​​opening 4041 can be larger than the area of ​​feed port 401, ensuring that the fertilizer dropped from feed port 401 falls completely into storage bin 404; when movable plate 422 is about to move to the position of discharge port 402, baffle plate 4231 of push assembly 423 closes feed port 401, ensuring that no additional fertilizer flows from feed port 401 into storage bin 404 before adjustment mechanism 420 discharges the material; and then push assembly 423 continues to drive movable plate 422 to move to the left, until all fertilizer flows out from the gap between movable plate 422 and discharge port 402, to realize fertilization operation.

[0062] In one embodiment, the push assembly 423 further includes a push rod 4232 and a movable block 4233 connected to the push rod 4232. The push rod 4232 is moved to adjust the position of the movable block 4233 in the storage bin 404 to control the storage volume of the storage bin 404, thereby controlling the single fertilizer application amount of the fertilizing mechanism 400 to ensure 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 push assembly 423. Specifically, the push assembly 42 A mounting hole is provided on one side of the push rod 4232, through which the push rod 4232 is disposed. 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 method 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 adjusting 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 demand of different tobacco plantings.

[0063] In one embodiment, a return spring 424 is provided on one side of the pushing component 423, and a fixed plate 425 is provided on one side of the lower end of the fertilizer box 410. One end of the return spring 424 is connected to the fixed plate 425. The pushing component 423 moves in a direction away from the fixed plate 425 under the drive of an external driving device, thereby pushing the pre-stored fertilizer in the storage bin 404 to the discharge port 402 and dropping it into the hole 500 punched by the puncher 320 to achieve fertilization operation; when the pushing component 423 needs to return to its original position, the restoring force of the return spring 424 can be used to drive the pushing component 423 to return to its original position, thereby achieving the back and forth operation of the pushing component 423.

[0064] In this embodiment, the external driving device can use an external driving motor 311 combined with a cable to drive the pushing component 423 to move. For example, one end of the cable is connected to the pushing component 423, and after the middle part of the cable is wound around the pulley, the other end of the cable is connected to the rotating shaft 221 of the external driving motor 311, and the external driving motor 311 and the pulley can be fixed at the lower end of the fertilizer box 410; in other embodiments, the external driving device can also use an external driving motor 311 combined with a screw transmission, or a pushing cylinder combined with a pushing rod structure, etc.

[0065] In one embodiment, the punching mechanism 300 also includes a first controller, which is used to control the operating state of the first driving mechanism 100. The fertilizing mechanism 400 also includes a second controller, which is used to control the operating state of the adjusting mechanism 420. Further, the second controller is used to control the operating state of the pushing component 423.

[0066] Specifically, when the punching mechanism 300 starts the punching operation, the first controller controls the first driving mechanism 310 to drive the puncher 320 to move downward a preset distance, and sends a signal to the second controller, and the second controller controls the external driving device to drive the pushing component 423 to move; when the second controller detects that the puncher 320 moves downward another distance, in this embodiment, the second controller detects that the puncher 320 moves downward to the maximum punching depth, and sends a signal to the second controller. At this time, the pushing component 423 drops all the pre-stored fertilizers in the storage bin 404 from the discharge port 402, and the second controller begins to control the pushing component 423 to perform a return movement to prepare for the next round of fertilization operations.

[0067] In one embodiment, a handrail 140 is provided on the frame 110, and the handrail 140 is rotatably provided on the frame 110, so that the operator can grasp the handrail 140 from the groove on the side of the ridge, and adjust the force applied to the handrail 140 to adjust the travel direction of the driving wheel 130, so that the device of the present invention can perform cultivation operations on winding ridges.

[0068] In one embodiment, the fertilizer mechanism 400 also includes a fertilizer drop plate 430, which is arranged above the punch 320. Specifically, the fertilizer drop plate 430 is matched and arranged between the discharge port 402 of the adjusting mechanism 420 and the punch 320 to separate the fertilizer dropped from the discharge port 402 of the adjusting mechanism 420 to increase the fertilization area of ​​the fertilizer; the fertilizer drop plate 430 includes two parallel support rods 431, and a plurality of inverted "V"-shaped blocking pieces 432 are arranged between the two support rods 431, and there is a gap between two adjacent blocking pieces 432. The fertilizer dropped from the discharge port 402 will fall into the hole position 500 from both sides of the blocking piece 432 under the guiding action of the blocking piece 432, thereby effectively increasing the fertilization area of ​​the fertilizer mechanism 400.

[0069] In one embodiment, a soil retaining cover 600 is provided on the outer side of the rotary tillage mechanism 200, and the soil retaining cover 600 is fixedly arranged on the support frame 210. The soil retaining cover 600 includes two side plates 610, and the two side plates 610 are arranged in parallel. When the rotary tillage mechanism 200 performs land preparation and loosening operations, the side plates 610 can effectively prevent the loosened soil from falling into the grooves on both sides of the ridge, thereby ensuring the efficient utilization rate of the loosened soil; when the rotary tillage mechanism 200 moves along its moving direction, a small amount of the bottom of the front end of the side plate 610 will also sink into the soil. The bottom of the front end of the side plate 610 is a circular arc structure, which can effectively reduce the resistance of the soil to the travel path of the side plate 610; the rear end of the side plate 610 is bent inward to provide a limiting plate 620, and the limiting plate 620 is used to gather the soil loosened by the rotary tillage mechanism 200 to improve the stability of the hole position 500.

[0070] An upper cover plate 630 is arranged above the side plate 610, and the upper cover plate 630 is arranged above the rotary tiller 220. The front end and the rear end of the upper cover plate 630 are respectively provided with inclined panels 631 to block the soil turned over by the rotary tiller 220 to prevent the turned soil from being separated from the ridge and affecting the ridge-forming quality; a rear baffle plate 640 is arranged above the rear end of the side plate 610, and the rear baffle plate 640 is inclined at an acute angle to the ground. The rear baffle plate 640 is arranged close to the punching mechanism 300 to prevent the soil thrown out by the puncher 320 during the upward movement from flying out of the soil retaining cover 600.

[0071] When the present invention is working, the rotary tillage mechanism 200 moves and drives the punching mechanism 300 and the fertilizing mechanism 400 to move together. At this time, the third driving mechanism 230 drives the rotary tiller 220 to move, so as to perform rotary tillage operation on the ground on the moving route; when it is necessary to perform a punching operation on the loosened soil on the moving route, the first driving mechanism 310 drives the puncher 320 to move up and down. When the puncher 320 moves up and down, the retaining plate 321 on the puncher 320 completely blocks the rotary tillage mechanism 200. The loosened soil is guided to form a plurality of hole positions 500 on the ground along the moving route; while the puncher 320 is performing the punching operation, the fertilizing mechanism 400 also starts the fertilizing operation, and the external driving device drives the pushing component 423 to push the pre-stored fertilizer in the storage bin 404 to the discharge port 402, and the fertilizer falls into the hole positions 500 punched by the puncher 320, thereby realizing the synchronous operation of mechanized punching and fertilization, reducing labor intensity, effectively ensuring the uniformity of fertilization, and meeting the needs of tobacco planting.

[0072] In this embodiment, the specific cooperation process between the fertilizing mechanism 400 and the punching mechanism 300 is as follows: in the initial state, the punch 320 is a certain distance above the ground. In this embodiment, the height of the punch 320 from the ground in the initial state is 5 cm. After the first driving mechanism 310 drives the punch 320 to move downward by 5 cm, the external driving device starts to drive the pushing component 423, and the fertilizing mechanism 400 changes from the pre-stored fertilizer state to the fertilizing state. When the punch 320 reaches the maximum punching depth, the pushing component 423 All the pre-stored fertilizers in the storage bin 404 are dropped from the discharge port 402, and the fertilizing mechanism 400 completes the discharge operation of the fertilizers; the puncher 320 is driven by the first driving mechanism 310 to return to its original position, and when the puncher 320 is out of the ground, that is, when the puncher 320 is 5 cm away from the original position, the pushing assembly 423 is driven by the external driving device to return to its original position, and the fertilizer in the fertilizer box 410 enters the storage bin 404 from the feed port 401, and the fertilizing mechanism 400 re-enters the pre-stored fertilizer state.

[0077] S3, the first driving mechanism 310 drives the puncher 320 to move downward to reach the maximum punching depth, the pushing component 423 causes all the pre-stored fertilizers in the storage bin 404 to drop from the discharge port 402, and the fertilizing mechanism 400 completes the discharge operation of the fertilizers;

[0078] S4. The puncher 320 moves upward under the drive of the first driving mechanism 310 and gradually returns to the initial position of the puncher 320. The pushing component 423 also gradually returns to the initial position of the pushing component 423 under the drive of the external driving device. The fertilizer in the fertilizer box 410 enters the storage bin 404 from the feed inlet 401, and the fertilizing mechanism 400 re-enters the pre-stored fertilizer state.

[0079] In one embodiment, before step S1, the step further includes

[0080] S5. According to the size of the hole positions 500 and the spacing between the hole positions 500, the operating parameters of the rotary tillage mechanism 200 and the punching mechanism 300 are adjusted; wherein, the up and down reciprocating motion cycle of the punch 320 = the hole spacing / the moving speed of the rotary tillage mechanism 200, and the hole spacing is the spacing between the bottom ends of two adjacent hole positions 500; the operating parameter of the rotary tillage mechanism 200 is the moving speed of the rotary tillage mechanism 200, and the operating parameter of the punching mechanism 300 is the sliding speed of the slide bar 315 during the reciprocating motion on the slide rail 314.
