[0025] Embodiment 2: Referring to Figures 1 - 7 and Figure 10 , which is the second embodiment of the present invention, a seeding maize weeding and soil covering tiller is provided. The lifting assembly includes a fixed rack 203, which is fixedly installed on one side of the partition plate 201. Connecting blocks 204 are symmetrically installed at both ends of the fixed rack 203, and sliding columns 205 are slidably connected to the connecting blocks 204.

[0026] A reset elastic piece 206 is sleeved on the sliding column 205. Movable teeth 207 are provided at both ends of the fixed rack 203. One side of the movable tooth 207 is fixedly connected to the sliding column 205. The movable tooth 207 is slidably connected to one side of the partition plate 201. A driving gear 208 is meshed with one side of the fixed rack 203.

[0027] The delay component includes a coordination gear 209 sleeved on a driving gear 208. A driven block 210 is fixedly installed on one side of the coordination gear 209. An active block 211 is slidably connected to one side of the driven block 210. The active block 211 is sleeved on the driving gear 208. One end of the driving gear 208 is fixedly connected to a coordination block 212. There are abutting columns on the driven block 210, the active block 211 and the coordination block 212. The abutting columns are respectively fixedly connected to one side of the driven block 210 and the coordination block 212. The surfaces where the driven block 210 and the coordination block 212 are located are symmetrical. The end of the coordination block 212 that cannot be close to the abutting column set on the driven block 210 does not fit in contact. Both sides of the active block 211 are provided with abutting columns, which can simultaneously abut and drive the driven block 210 and the coordination block 212.

[0028] A support frame 213 is arranged between the driving gear 208 and the coordination gear 209. The support frame 213 is sleeved on the gear shaft of the driving gear 208. The bottom end of the support frame 213 is fixedly connected to the surface of the protective cover 100. A fixed frame 214 is fixedly connected to one side of the protective cover 100. A driven gear 215 is rotatably connected to the fixed frame 214. The driven gear 215 meshes with the upper coordination gear 209.

[0029] One side of the driven gear 215 is fixedly connected to a rotating block 216. Both ends of the rotating block 216 are connected with pawls 217 by torsion springs. One side of the rotating block 216 is rotatably connected to a ratchet ring 218. The rotating block 216 is arranged inside the ratchet ring 218. One side of the ratchet ring 218 is fixedly connected to a reciprocating lead screw 219.

[0030] A sliding sleeve 220 is sleeved on the reciprocating lead screw 219. A sliding groove 221 is opened on one side of the protective cover 100. One end of the sliding sleeve 220 is slidably connected in the sliding groove 221. One end of the sliding sleeve 220 is fixedly connected to the surface of the scraping plate 202. One end of the driving gear 208 is fixedly installed with a driving motor 222. There are two groups of the reciprocating lead screw 219 and the sliding sleeve 220. The two groups of sliding sleeves 220 move towards each other along their respective reciprocating lead screws 219. One sliding sleeve 220 on one side moves to the left, and the other sliding sleeve 220 on the other side moves to the right. The length of the sliding groove 221 is the same as that of the two groups of sliding grooves 221 above.

[0031] Specifically, initially, the baffle plate 201 is not lifted and is in a closed state, which can block impurities and prevent them from splashing onto the scraper plate 202 and adhering to it, and the scraper plate 202 is limited in the protective cover 100, and the coordination block 212 is in a vertical state. The movable block 211 is on one side of the coordination block 212 and conflicts with the coordination block 212, and contacts the arc surface of the column on one side of the coordination block 212 and the column on the corresponding side of the movable block 211 through the contact, and the driven block 210 is on the other side of the coordination block 212. It is in a horizontal state and does not conflict with the movable block 211 and the coordination block 212. The driven block 210 is staggered with the movable block 211 and the coordination block 212, and the column on one side of the coordination block 212 and the column on the corresponding side of the driven block 210 are separated by the movable block 211, so that the column on the coordination block 212 does not contact the column on the driven block 210. Figure 4 and Figure 10 As shown; The output end of the driving motor 222 drives the driving gear 208 to rotate on the support frame 213, and drives the coordination block 212 fixed at one end of the driving gear 208 to rotate together. Since the length of the support column of the coordination block 212 and the driven block 210 is short, when the coordination block 212 and the driven block 210 are horizontal, the two support columns do not contact, so that the coordination block 212 passes through the driven block 210, so that the movable block 211 on one side that is not interfered with rotates to a vertical state under the action of gravity, and the coordination gear 209 is sleeved on the driving gear 208 and meshes with the driven gear 215 below to generate resistance, so that the driving gear 208 rotates. When the gear 208 is in motion, the sleeved coordination gear 209 does not rotate. The driving gear 208 rotates and drives the meshed fixed rack 203 on one side to slide upward, driving the baffle plate 201 in the protective cover 100 to start sliding upward. The baffle plate 201 can scrape off the impurities intercepted on the baffle plate 201 while rising along the protective cover 100. When the coordination block 212 rotates a circle and returns to the other side of the movable block 211 in the vertical state, it will conflict with the movable block 211 again. The support column on one side of 212 conflicts with the arc surface of the support column on one side of 211, and pushes the conflicting movable block 211 to rotate together. At the same time, after the driving gear 208 rotates to lift the fixed rack 203 engaged on one side, the driving gear 208 rotates to contact the movable tooth 207 at the bottom of the fixed rack 203, pushing the movable tooth 207 to slide along one side of the baffle plate 201. The sliding of the movable tooth 207 pushes the sliding posts 205 on both sides to slide along the connecting block 204, squeezing the reset spring piece 206 sleeved on the sliding post 205, so that the driving gear 208 rotates to keep pushing the fixed rack 203 to be in a lifted state; Subsequently, when the coordination block 212 pushes the movable block 211 to rotate until it contacts the driven block 210, the support column on one side of the coordination block 212 pushes and contacts the arc surface of the support column on one side of the movable block 211, so that the support on the other side of the movable block 211 contacts the support column of the driven block 210 on the corresponding side, and drives them to rotate together, so that the driven block 210 rotates together with the driving gear 208, driving the meshing driven gear 215 below to rotate together on the fixed frame 214, and the rotation of the driven gear 215 will drive the fixed rotating block 216 on one side to rotate together, and the pawls 217 at both ends of the rotating block 216 will contact the inner wall of the ratchet ring 218, and drive the reciprocating screw 219 on one side of the ratchet ring 218 to rotate together, driving the sliding sleeve 220 sleeved on the reciprocating screw 219 to slide back and forth, and the slide plate on one side of the sliding sleeve 220 passes through the sliding groove 221 to drive the scraper The plate 202 slides along the inner wall of the protective cover 100. When the slide plate slides along the sliding groove 221, it can clean up the impurities splashed into the sliding groove 221 and the impurities on the inner wall of the protective cover 100. When the sliding sleeve 220 drives the scraper plate 202 to return from the middle position to the initial end, the output end of the driving motor 222 drives the driving gear 208 to rotate in the opposite direction. The steps are opposite to this. The driving gear 208 drives the fixed rack 203 on one side to slide downward. The movable teeth 207 at the top of the fixed rack 203 have the same effect as the movable teeth 207 at the bottom, so that after the baffle plate 201 is closed, the driving gear 208 can continue to rotate to drive the remaining structures to reset, and the rotating block 216 will drive the ratchet pawls 217 at both ends to rotate in the ratchet ring 218, so that the driven block 210, the movable block 211 and the coordination block 212 all return to the initial position.

[0032] Example 3: Reference Figure 2 and Figures 5 - 9 , which is the third embodiment of the present invention, provides a seed corn weeding and soil covering tillage machine, the removal component includes a limit groove 303, the limit groove 303 is opened on the baffle plate 201, one end of the tool 301 is sleeved with a push column 304, the push column 304 is slidably connected to one side of the protective cover 100, the push column 304 is sleeved with a push spring 305, the limit groove 303 consists of a bevel groove and a groove, which can limit the tool 301.

[0033] One end of the tool 301 is fixedly connected to a driven disk 306, and one side of the protective cover 100 is rotatably connected to a driving disk 307. A coordination disk 308 is arranged between the driven disk 306 and the driving disk 307. A belt 309 is sleeved between the driven disk 306 and the coordination disk 308. One end of the belt 309 is sleeved on the driving disk 307. One side of the coordination disk 308 is rotatably connected to a sliding block 310. The sliding block 310 is slidably connected in the protective cover 100. A coordination spring 311 is installed on the lower surface of the sliding block 310. The belt 309 is sleeved on the driven disk 306, the driving disk 307 and the coordination disk 308. A motor is arranged on one side of the driving disk 307.

[0034] A pushing frame 312 is sleeved on the tool 301, and the bottom end of the pushing frame 312 is fixedly connected to a limiting block 313. The inner wall of the protective cover 100 is symmetrically provided with moving grooves 314, and the limiting block 313 is slidably connected in the moving grooves 314. The protective cover 100 is symmetrically provided with removal grooves 315. The top of the pushing frame 312 is rotatably connected to a pushing block 316. Adjustment grooves 317 are provided at both ends of the flip plate 302, and the pushing block 316 is slidably connected in the adjusting grooves 317.

[0035] Specifically, initially, when the baffle plate 201 is not lifted, the cutter 301 is clamped in the groove in the limiting groove 303, the push spring 305 between the push column 304 and the protective cover 100 is in a compressed state, the flip cover plate 302 on one side of the protective cover 100 is also in a closed state, and the coordination spring 311 lifts the coordination disk 308, so that the belt 309 sleeved on the driven disk 306, the driving disk 307 and the coordination disk 308 presents a triangle; As the baffle plate 201 is lifted, the cutter 301 will gradually disengage from the slot, and the compressed push spring 305 will push the cutter 301 to gradually slide along the inclined groove of the limit groove 303 under the reaction force, and the cutter 301 will slide toward the side of the flip cover plate 302 along the removal grooves 315 on both sides. At the same time, when the driven disk 306 moves with the cutter 301, it will pull the sliding block 310 on one side of the coordination disk 308 to slide downward and squeeze the coordination spring 311 through the sleeved belt 309, so that the belt 309 sleeved between the driven disk 306 and the driving disk 307 can be kept in a tight state, ensuring that the cutter 301 can continue to work after being reset; The top of the push frame 312 will gradually push open the flip plate 302 on one side of the protective cover 100, so that the flip plate 302 can rotate on the protective cover 100, and the push block 316 on the top of the push frame 312 will also slide in the adjustment groove 317. When the tool 301 is removed, it can be easily cleaned and maintained, and impurities scraped off from the protective cover 100 can be prevented from falling onto the tool 301. The tool 301 can be driven to slide and reset along the inclined groove by the descending of the baffle plate 201, and the steps are opposite to those of the tool 301.

[0036] Example 4: Reference Figures 1 - 10 , which is a fourth embodiment of the present invention, provides a seed corn weeding and soil covering tillage machine, comprising the following steps: Initially, the baffle plate 201 is not lifted and is in a closed state, which can block impurities and prevent them from splashing onto the scraper plate 202. The scraper plate 202 is limited in the protective cover 100, and the coordination block 212 is in a vertical state. The movable block 211 is on one side of the coordination block 212 and conflicts with the coordination block 212. The driven block 210 is on the other side of the coordination block 212 and is in a horizontal state, and does not conflict with the movable block 211 and the coordination block 212. Figure 4 As shown; The output end of the driving motor 222 drives the driving gear 208 to rotate on the support frame 213, and drives the coordination block 212 fixed at one end of the driving gear 208 to rotate together, so that the movable block 211 on one side that is not interfered with by gravity rotates to a vertical state, and the coordination gear 209 is sleeved on the driving gear 208 and meshes with the driven gear 215 below to generate resistance, so that when the driving gear 208 rotates, the sleeved coordination gear 209 does not rotate. While the driving gear 208 rotates, it will drive the meshed fixed rack 203 on one side to slide upward, and drive the baffle plate 201 located in the protective cover 100 to start sliding upward. While the baffle plate 201 rises along the protective cover 100, it can scrape off the impurities intercepted on the baffle plate 201. When the coordination block 212 rotates a circle and returns to the side of the movable block 211 in the vertical state, it will conflict with the movable block 211 again, and push the conflicting movable block 211 to rotate together; Meanwhile, after the driving gear 208 rotates to lift the fixed rack 203 engaged on one side, the driving gear 208 rotates and abuts against the movable tooth 207 at the bottom end of the fixed rack 203, pushing the movable tooth 207 to slide along one side of the partition plate 201. The sliding of the movable tooth 207 pushes the sliding columns 205 on both sides to slide along the connecting block 204, squeezing the reset elastic pieces 206 sleeved on the sliding columns 205, so that the rotation of the driving gear 208 always pushes the fixed rack 203 to be in the lifted state; Subsequently, when the coordination block 212 pushes the movable block 211 to rotate until it abuts against the driven block 210 and drives it to rotate together, the driven block 210 rotates together with the driving gear 208, driving the driven gear 215 engaged below to rotate together on the fixed frame 214. The rotation of the driven gear 215 drives the fixed rotating block 216 on one side to rotate together. The pawls 217 at both ends of the rotating block 216 abut against the inner wall of the ratchet ring 218 and drive the reciprocating lead screw 219 on one side of the ratchet ring 218 to rotate together, driving the sliding sleeve 220 sleeved on the reciprocating lead screw 219 to slide back and forth. The sliding sleeve 220 passes through the sliding groove 221 to drive the scraping plate 202 to slide along the inner wall of the protective cover 100, cleaning the impurities on the inner wall of the protective cover 100. When the sliding sleeve 220 drives the scraping plate 202 to return to the initial end from the middle position, the output end of the driving motor 222 drives the driving gear 208 to rotate in the reverse direction. The steps are opposite. The driving gear 208 drives the fixed rack 203 on one side to slide downward, and the rotating block 216 drives the pawls 217 at both ends to rotate in the ratchet ring 218, so that the driven block 210, the movable block 211 and the coordination block 212 all return to the initial positions; Initially, when the partition plate 201 has not been lifted yet, the cutting tool 301 is clamped at the groove in the limiting groove 303. The pushing spring 305 between the pushing column 304 and the protective cover 100 is in a compressed state, and the flip cover plate 302 on one side of the protective cover 100 is also in the closed state. The coordination elastic piece 311 holds up the coordination disk 308, making the belt 309 sleeved on the driven disk 306, the driving disk 307 and the coordination disk 308 present a triangular shape; As the partition plate 201 is lifted, the cutting tool 301 will gradually disengage from the card slot. Under the reaction force, the compressed pushing spring 305 will push the cutting tool 301 to gradually slide along the inclined groove of the limiting groove 303. The cutting tool 301 will slide along the moving-out grooves 315 on both sides towards the flip cover plate 302. Meanwhile, when the driven disk 306 moves together with the cutting tool 301, it will pull the sliding block 310 on one side of the coordination disk 308 to slide downward by the sleeved belt 309, squeezing the coordination elastic piece 311, so that the belt 309 sleeved between the driven disk 306 and the driving disk 307 can always be in a taut state, ensuring that the cutting tool 301 can still work after resetting; While the cutting tool 301 is moving, the pushing frames 312 sleeved at both ends of the cutting tool 301 will slide along with it. The limiting blocks 313 at the bottom ends of the pushing frames 312 slide along the moving grooves 314 on both sides of the inner wall of the protective cover 100. The top ends of the pushing frames 312 will gradually push open the turning cover plate 302 on one side of the protective cover 100, causing the turning cover plate 302 to rotate on the protective cover 100. The pushing blocks 316 at the top ends of the pushing frames 312 will also slide in the adjustment grooves 317. While moving the cutting tool 301 away, it is convenient to clean and maintain it, and at the same time, it can prevent the impurities scraped off inside the protective cover 100 from falling onto the cutting tool 301. By the lowering of the partition plate 201, the cutting tool 301 is driven to slide and reset along the inclined surface groove, and the steps are opposite.
