Description

Technical Field

[0001] This invention relates to the field of agricultural planting equipment technology, specifically to a high-efficiency sweet potato planting device for hilly dryland areas. Background Technology

[0002] Sweet potatoes are an important food, economic, and feed crop in my country, with a wide planting area. They play a vital role in ensuring food security, promoting agricultural efficiency, and increasing farmers' income. The planting process is a key step in the entire sweet potato planting process, and its quality directly affects the emergence rate, growth status, and final yield of sweet potatoes. Sweet potato planting methods are divided into manual planting and mechanical planting. The operation process of both manual and mechanical planting mainly includes steps such as trenching, seedling placement, soil covering, and compaction.

[0003] When sweet potatoes are mechanically planted horizontally, they are placed on the surface of the ridges perpendicular to the direction of the ridges. They need to be covered with soil and then compacted. The position of the sweet potato seedlings is not fixed and they are prone to displacement. Furthermore, compaction requires additional operations, which increases the planting time. Therefore, this method does not meet the existing needs. To address this, we propose a high-efficiency sweet potato planting device for hilly dry land. Summary of the Invention

[0008] Preferably, the transmission module includes a synchronous gearbox and a reduction gearbox. The synchronous gearbox is fixed to the fixed plate, and the output motor is fixed to the outside of the output motor. The synchronous gearbox has one drive input shaft and three drive output shafts. The output shaft of the output motor is connected to the drive input shaft. One of the drive output shafts is on the same side as the drive input shaft, and the other two drive output shafts are located on the other side of the synchronous gearbox and are respectively connected to the ends of the dividing shaft and the rotary tillage shaft.

[0009] Preferably, the reduction gearbox is fixed on the outer side of the end of the connecting support plate away from the fixed plate. The reduction gearbox has two drive shafts. One of the drive shafts is connected to the end of the linkage shaft. The other drive shaft and the drive output shaft on the same side as the drive input shaft are both fixed with synchronous pulleys. Synchronous belts are sleeved on the outer sides of the two synchronous pulleys and are driven through the synchronous belts.

[0010] Preferably, a ridge-splitting module is provided between the ridge-splitting roller and the protective shell. The ridge-splitting module includes a support rod, the two ends of which are respectively fixed to the upper surface of two fixed plates. Multiple fixed connecting rods are fixed to the bottom of the support rod. A ridge-splitting plow is fixed to the bottom end of the fixed connecting rod. A protective shielding block is fixed to the rear end of the ridge-splitting plow. The protective shielding block is located between two adjacent ridge-splitting rollers, and the side of the protective shielding block is in sliding contact with the end face of the ridge-splitting roller.

[0011] Preferably, the top of the protective shielding block is provided with a reserved groove, the dividing shaft passes through the middle of the reserved groove, and the diameter of the reserved groove is equal to the diameter of the dividing shaft.

[0012] Preferably, two baffles are fixed on the upper surface of the end of the support rod that connects to the dividing plow head.

[0013] Preferably, the slotted compaction module further includes a fixed connecting plate, one end of which is fixed to the support rod, and the other end of which is fixed with a suspended support plate and a guide rod, and the end of the guide rod away from the fixed connecting plate is provided with a rectangular groove.

[0014] Preferably, the top end of the transmission frame passes through the inside of the rectangular groove, and the size of the rectangular groove is the same as the cross-sectional size of the top end of the transmission frame.

[0015] Preferably, one end of the suspended support plate is located inside the transmission disk, and the inner side of the transmission disk is provided with two connecting ring grooves. A supporting arc strip is engaged inside the connecting ring groove, and the supporting arc strip is fixed to the outer side of the end of the suspended support plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention utilizes a transmission module to transmit power to a linkage shaft, which drives the transmission disc to rotate via a transmission pulley and belt. The transmission disc, transmission connecting rod, and transmission frame reciprocate in a crank motion, causing the grooving strip to move back and forth in a straight line and grooves the top of the ridges after ridging. This allows sweet potato seedlings to be placed at fixed points and at equal intervals. The soil covering plate slides against the surface of the ridges, pushing the soil into the grooves created by the grooving strip to cover and compact the sweet potato seedlings. This simplifies the planting process, shortens the planting time, and thus improves planting efficiency.

[0018] 2. This invention sets up a ridge-shaping module between two adjacent ridge-shaping rollers, and uses a ridge-shaping plow to move the loosened soil towards the middle of the ridge-shaping rollers, so that the ridge-shaping rollers can compact the soil to form ridges. The protective shielding block slides against the side of the ridge to compact and correct the side of the ridge, preventing the soil from loosening and collapsing after being squeezed by the ridge-shaping rollers.

[0019] 3. The present invention provides a baffle with a contact curved surface between the protective shielding block and the ridge-separating roller to block the gap between the protective shielding block and the ridge-separating roller, thereby preventing soil from entering between the protective shielding block and the ridge-separating roller and hindering the rotation of the ridge-separating roller.

[0020] 4. This invention utilizes adjacent slotted pressing strips to move in different directions. When the tiller moves forward at a constant speed, the slotted pressing strips that move up and down move alternately and create slots of the same width on the surface of the compacted soil ridge, which are evenly distributed along the length of the soil ridge. This achieves even and orderly planting of sweet potato seedlings. The orderly spacing avoids the sweet potatoes from squeezing each other due to insufficient space after they grow.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] like Figure 1 and Figure 2As shown, a high-efficiency sweet potato planting device for hilly dry land includes a soil loosening module 1 and an output motor 3. The soil loosening module 1 includes a protective shell 101, a connecting column 102 is detachably installed on the top of the protective shell 101, and a fixing plate 105 is fixed at both ends of the protective shell 101.

[0031] A rotary tillage shaft 103 is rotatably inserted between two fixed plates 105. Multiple rotary tillage blades 104 are fixed on the outer surface of the rotary tillage shaft 103. A ridge-shaping shaft 106 is rotatably inserted between the other ends of the two fixed plates 105. Multiple ridge-shaping rollers 107 are fixed on the outer surface of the ridge-shaping shaft 106. The rotary tillage blades 104 are used to break up and loosen the soil. The ridge-shaping rollers 107 are used to gather and compact the loosened soil under the ridge-shaping rollers 107, thus creating ridges suitable for planting sweet potato seedlings in the field.

[0032] like Figure 1 and Figure 5 As shown, a transmission module 2 is installed on the outside of one of the slotted compaction modules 5. The transmission module 2 includes a synchronous gearbox 201 and a reduction gearbox 206. The synchronous gearbox 201 is fixed to the fixed plate 105. The output motor 3 is fixed on the outside of the output motor 3. The synchronous gearbox 201 has one drive input shaft 202 and three drive output shafts 203. The output shaft of the output motor 3 is connected to the drive input shaft 202. One of the drive output shafts 203 is on the same side as the drive input shaft 202. The other two drive output shafts 203 are located on the other side of the synchronous gearbox 201 and are respectively connected to the ends of the ridge-dividing shaft 106 and the rotary tillage shaft 103. The rotary tillage shaft 103 and the ridge-dividing shaft 106 are rotated simultaneously through the output motor 3, the synchronous gearbox 201, the drive input shaft 202 and the drive output shaft 203, so that the soil loosening and ridge compaction operations can be carried out at the same time.

[0033] The reduction gearbox 206 is fixed on the outer side of the end of the connecting support plate 501 away from the fixed plate 105. The reduction gearbox 206 has two drive shafts 207. One drive shaft 207 is connected to the end of the linkage shaft 504. The other drive shaft 207 and the drive output shaft 203 on the same side as the drive input shaft 202 are both fixed with synchronous pulleys 204. Synchronous belts 205 are sleeved on the outer side of the two synchronous pulleys 204 and are driven through the synchronous belts 205. While the rotary tillage shaft 103 and the ridge-dividing shaft 106 are running, the power is transmitted and the linkage shaft 504 is rotated simultaneously through the reduction gearbox 206 and the drive shaft 207, so that the grooving and compaction module 5 grooves on the surface of the soil ridge formed after the ridge roller 107 compacts the soil.

[0034] like Figure 1 , Figure 3 and Figure 4As shown, a ridge-shaping module 4 is provided between the ridge-shaping roller 107 and the protective shell 101. The ridge-shaping module 4 includes a support rod 401. Both ends of the support rod 401 are fixed to the upper surfaces of two fixed plates 105 respectively. Multiple fixed connecting rods 402 are fixed to the bottom of the support rod 401. A ridge-shaping plow head 403 is fixed to the bottom end of the fixed connecting rod 402. A protective shielding block 404 is fixed to the rear end of the ridge-shaping plow head 403. The protective shielding block 404 is located between two adjacent ridge-shaping rollers 107, and the side of the protective shielding block 404 slides in contact with the end face of the ridge-shaping roller 107. By moving the ridge-shaping plow head 403 in the broken soil, the loosened soil is transferred to the area below the ridge-shaping roller 107, so that the ridge-shaping roller 107 compacts the soil and forms ridges.

[0035] The top of the protective shielding block 404 is provided with a reserved groove 405. The dividing shaft 106 passes through the middle of the reserved groove 405, and the diameter of the reserved groove 405 is equal to the diameter of the dividing shaft 106. Two baffles 406 are fixed on the upper surface of the end where the support rod 401 is connected to the dividing plow head 403. The outer side of the baffle 406 is provided with a contact curved surface 407. The radius of curvature of the contact curved surface 407 is the same as the radius of the end of the contact curved surface 407. The baffle 406 is located between the end of the protective shielding block 404 and the end of the dividing roller 107, which plays a role in shielding the soil and preventing the soil from passing through the gap between the protective shielding block 404 and the end of the dividing roller 107, so that the soil is concentrated below the dividing roller 107 and the soil height is not insufficient due to soil reduction.

[0036] like Figure 1 , Figure 6 and Figure 7As shown, a slotted compaction module 5 is fixed between the ends of two fixed plates 105. The slotted compaction module 5 includes two connecting support plates 501. One end of the connecting support plate 501 is fixed to the fixed plate 105, and a connecting frame 502 is fixed to the end of the connecting support plate 501 away from the fixed plate 105. Soil-covering compaction plates 503 are fixed to the bottom of the two connecting frames 502. A linkage shaft 504 is driven between the two connecting support plates 501. Multiple transmission pulleys 508 are fixed to the outside of the linkage shaft 504. A transmission disc 510 is provided directly below the transmission pulleys 508. A transmission belt 509 is provided between the transmission pulleys 508 and the transmission disc 510, and the movement is transmitted through the transmission belt 509. Both sides of 510 are equipped with transmission connecting rods 511, and both ends of the transmission connecting rods 511 are inserted with connecting pins 514. One end of the connecting pin 514 is rotatably inserted into the inside of the transmission disc 510, and the other end of the connecting pin 514 is rotatably sleeved with a transmission frame 512. The bottom of the transmission frame 512 is fixed with a grooving strip 513. While rotary tillage and loosening the soil, the transmission module 2 transmits power to the linkage shaft 504, so that the linkage shaft 504 drives the transmission connecting rods 511 and the transmission frame 512 to move through the transmission pulley 508, the transmission belt 509, and the transmission disc 510. This causes the grooving strip 513 to move up and down and grooves the top of the soil ridge after ridging, so as to achieve fixed placement of sweet potato seedlings.

[0037] The slotted compaction module 5 also includes a fixed connecting plate 505. One end of the fixed connecting plate 505 is fixed to the support rod 401, and the other end of the fixed connecting plate 505 is fixed with a suspended support plate 506 and a guide rod 507. The end of the guide rod 507 away from the fixed connecting plate 505 is provided with a rectangular groove. The top of the transmission frame 512 passes through the inside of the rectangular groove. The size of the rectangular groove is the same as the cross-sectional size of the top of the transmission frame 512. The movement of the transmission frame 512 is restricted by the guide rod 507, so that the transmission frame 512 can only slide back and forth in a straight line.

[0038] One end of the suspended support plate 506 is located inside the transmission disc 510. The inner side of the transmission disc 510 is provided with two connecting ring grooves 516. A support arc strip 515 is snapped into the inner side of the connecting ring groove 516. The support arc strip 515 is fixed to the outer side of the end of the suspended support plate 506. By using the support arc strip 515 to snap into the inside of the connecting ring groove 516, the transmission disc 510 is suspended and supported without affecting the free rotation of the transmission disc 510, thus ensuring the smooth operation of the equipment.

[0039] When planting sweet potato seedlings, the protective shell 101 is connected to the tiller through the connecting column 102. The tiller is started and the power of the output motor 3 is connected and started. The sweet potato seedlings to be planted are placed inside the automatic seedling feeding mechanism located between the soil covering plate 503 and the grooving strip 513. The tiller moves along the length of the field.

[0040] During the movement, the output motor 3 transmits power to the rotary tiller 103, the ridge-separating shaft 106, and the linkage shaft 504 through the transmission module 2. When the power is transmitted to the rotary tiller 103, the rotary tiller 103 rotates rapidly and drives the rotary tiller blades 104 to operate. The rotary tiller blades 104 break up the soil. As the rotary tiller blades 104 continuously break up the soil, the ridge-separating plow head 403 moves with the tiller. The broken soil accumulates along the inclined surface of the ridge-separating plow head 403 and below the ridge-separating pressure roller 107 as the ridge-separating plow head 403 moves. At this time, the ridge-separating shaft 106 drives the ridge-separating pressure roller 107 to rotate. The ridge-separating pressure roller 107 compacts the soil below it, so that the soil forms trapezoidal ridges.

[0041] After the soil ridge is formed, the protective shielding block 404 slides against the side of the soil ridge to correct and compact the side of the soil ridge, preventing the soil ridge from collapsing due to loosening of the side. After the soil ridge is compacted and shaped by the ridge pressing roller 107, the linkage shaft 504 drives the transmission belt 509 and the suspended support plate 506-0 to rotate through the transmission pulley 508. The transmission disc 510 drives the ends of the two transmission connecting rods 511 to make a circular motion around the axis of the transmission disc 510 through the connecting pin 514. At this time, the ends of the two transmission connecting rods 511 are up and down, so that the two transmission frames 512 are one up and one down. At this time, the adjacent grooving pressing strips 513 move in opposite directions. The grooving pressing strips 513 reciprocate linearly and press out grooves of the same width on the soil surface. The automatic seedling feeding mechanism for planting sweet potato seedlings puts the sweet potato seedlings into the pressed grooves.

[0042] As the tiller moves continuously, the reciprocating grooving strip 513 creates grooves on the surface of the soil ridge, arranged in a linear array along the length of the ridge. Simultaneously, the soil covering plate 503 creates grooves and slides on the surface of the soil ridge where the sweet potato seedlings are placed. The soil covering plate 503 pushes the soil from the surface of the soil ridge into the grooves after the sweet potato seedlings are placed. During the movement of the soil covering plate 503, the soil in the grooves is compacted, achieving simultaneous soil covering and compaction. This simplifies the planting process, shortens the planting time, and thus improves planting efficiency.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
