Description

Technical Field

[0001] The present invention belongs to the technical field of seeding, and specifically relates to a sod scarifier seeder. Background Art

[0002] Sod scarifying and seeding is a method for lawn reseeding, used to reseed sparse areas, fill bald spots or sparse parts in the lawn, or improve the lawn density and quality without completely renovating.

[0003] The traditional method is to first use tools to scarify the sod, such as using a rake to make shallow grooves or small holes in the existing sod. The main purpose is to break the dead grass layer on the surface of the lawn so that the seeds can contact the soil. Because the dead leaves form a solid hydrophobic layer on the surface of the lawn, if the dead grass layer is not properly treated, the sown grass seeds are not only prone to dehydration and death, but also the roots are difficult to penetrate the dead grass layer and reach deep into the soil.

[0004] Then, the grass seeds are evenly spread on the scarified sod, ensuring that the seeds fall into the scratches or holes and contact the soil. Then, gently cover the soil and compact it to help the seeds tightly combine with the soil and promote germination. Finally, water moderately to keep the soil moist, but avoid overwatering that may cause the seeds to wash away.

[0005] However, the working process of this method is relatively complicated. Different tools and machines are required. First, a rake is used to scarify the sod, and then the seeder is replaced to spread the seeds. It is difficult to complete the two tasks of scarifying the sod and spreading the grass seeds with a single mechanical tool. Summary of the Invention

[0006] To solve the problem of the relatively complicated working process proposed in the above background art, the present invention provides a sod scarifier seeder.

[0007] To achieve the above object, the present invention provides the following technical solution: A sod scarifier seeder includes a grass seed box, and moving rollers symmetrically distributed in pairs and installed on the side walls of the grass seed box. An armrest is installed between the left and right side walls of the grass seed box. A cylindrical roller is arranged below the grass seed box. A number of columns of first harrow plates are integrally fixed on the surface of the cylindrical roller, and a number of columns of first harrow plates are circumferentially equidistantly distributed on the cylindrical roller. A strip plate is arranged between adjacent two columns of first harrow plates, and the strip plate is attached to the surface of the cylindrical roller. A number of second harrow plates are arranged at equal intervals on each strip plate. The edges on both sides of the first harrow plates and the second harrow plates are blades. A first driving mechanism for driving the strip plate and the second harrow plates to move horizontally, and a second driving mechanism for driving the first harrow plates and the second harrow plates to rotate are arranged below the grass seed box. A matching component is arranged on the lower surface of the grass seed box.

[0008] Preferably, the first driving mechanism includes first electric telescopic rods fixed on the left and right side walls of the grass seed box. Both ends of the first electric telescopic rods are bent, and the end far from the grass seed box is fixedly connected with a rectangular bearing plate. A round shaft is rotatably connected between the two rectangular bearing plates. The cylindrical roller is sleeved on the round shaft, and the round shaft is driven by an external motor.

[0009] Preferably, on the side of each of the two rectangular bearing plates close to each other, there is a rotatably connected first annular sleeve. Two symmetrically distributed second electric telescopic rods are fixedly installed on the first annular sleeve. The ends of the two second electric telescopic rods far from the first annular sleeve are bent, and are fixedly connected with the same second annular sleeve. The round shaft is located within the second annular sleeve, and the strip plate is fixed on the second annular sleeve.

[0010] Preferably, the second driving mechanism includes a plurality of rectangular grooves opened at both ends of the round shaft and evenly distributed in a circumferential manner. A shaft sleeve is sleeved on the round shaft, and a rectangular slider that is slidably adapted to the rectangular groove is integrally fixed on the inner wall of the shaft sleeve.

[0011] Preferably, a ratchet wheel located within the second annular sleeve is sleeved on the shaft sleeve. On both opposite side walls of the second annular sleeve, two symmetrically distributed limiting rods are fixedly connected. The end of the limiting rod far from the second annular sleeve is L-shaped and fits on the surface of the ratchet wheel.

[0012] Preferably, at least one movable rod penetrates through the second annular sleeve. The end of the movable rod outside the second annular sleeve is fixedly connected with a handle. The end of the movable rod far from the handle is fixedly connected with a ratchet tooth that meshes with the ratchet wheel. A first spring sleeved on the movable rod is fixedly connected to the ratchet tooth. The end of the first spring far from the ratchet tooth abuts against the inner wall of the second annular sleeve.

[0013] Preferably, the matching assembly includes arc-shaped grooves opened on the left and right side walls of the grass seed box and adapted to the cylindrical roller. Bottom plates are telescopically inserted into the front and rear side walls of the grass seed box. On one side of the two bottom plates located inside the grass seed box, movable strips are fixedly connected.

[0014] Preferably, the lower surface of one of the movable strips is inclined, and the upper surface of the other movable strip is inclined, and the two inclined surfaces are in a parallel state.

[0015] Preferably, on one side of the two bottom plates located outside the grass seed box, bent rods are fixedly connected. A plug rod is telescopically inserted into the free end of the bent rod. The end of the plug rod far from the bent rod is fixedly connected to the outer side wall of the grass seed box. A second spring sleeved on the plug rod is fixedly connected between the grass seed box and the bent rod.

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

[0017] By setting the second driving mechanism, the first harrow floor and the second harrow floor can be driven to rotate simultaneously to complete the work of cutting the turf;

[0018] Moreover, the second driving mechanism can also drive the first harrow floor to rotate alone, so that the first harrow floor can fit together with the second harrow floor;

[0019] After cutting the turf, it is necessary to trim the degraded lawn and cut off the too-high grass leaves on the lawn to prevent the too-high grass leaves from covering the grass seeds and affecting the germination of the grass seeds;

[0020] Then, by setting the first driving mechanism, the second harrow floor can be driven to reciprocate horizontally in the state where the first harrow floor and the second harrow floor are mutually attached. Since the edges on both sides of the first harrow floor and the second harrow floor are blades, the second harrow floor can cooperate with the first harrow floor to form a mowing operation when reciprocating horizontally, complete the mowing work, and cut off the too-high grass leaves on the lawn.

[0021] By setting the cooperation component, the first harrow floor and the second harrow floor can rotate simultaneously in the state of being mutually attached, and cooperate with the grass seed box to complete the seeding work. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0033] As Figure 1 shown, the present invention provides a turf cutting seeding machine, including a grass seed box 11, and moving rollers 12 installed on the side walls of the grass seed box 11 and symmetrically distributed in pairs, and a handrail 13 is installed between the two side walls of the grass seed box 11

[0034] Among them, the handrail 13 enables the planting personnel to hold and control the moving direction of the whole seeding machine, while the moving rollers 12 enable the seeding machine to move conveniently to the sparse parts of the lawn

[0035] As Figure 1 and Figure 2 shown, a cylindrical roller 21 is arranged below the grass seed box 11. A number of columns of first harrow floors 22 are integrally fixed on the surface of the cylindrical roller 21, and a number of columns of first harrow floors 22 are circumferentially equidistributed on the cylindrical roller 21. A strip plate 23 is arranged between adjacent two columns of first harrow floors 22, and the strip plate 23 is attached to the surface of the cylindrical roller 21. A number of second harrow floors 24 are arranged on each strip plate 23 at equal intervals

[0036] Among them, the first harrow floor 22 and the second harrow floor 24 are used to cut the turf. When the first harrow floor 22 and the second harrow floor 24 are both in a rotating state, and the first harrow floor 22 and the second harrow floor 24 can contact the lawn during rotation, then the first harrow floor 22 and the second harrow floor 24 can act as a rake to cut the turf

[0037] At the edges on both sides of the first harrow floor 22 and the second harrow floor 24 are blades. Below the grass seed box 11, there is a first driving mechanism for driving the strip plate 23 and the second harrow floor 24 to move horizontally, and a second driving mechanism for driving the first harrow floor 22 and the second harrow floor 24 to rotate.

[0038] By setting the second driving mechanism, the first harrow floor 22 and the second harrow floor 24 can be driven to rotate simultaneously to complete the work of cutting the turf.

[0039] And the second driving mechanism can also drive the first harrow floor 22 to rotate alone, so that the first harrow floor 22 can fit together with the second harrow floor 24 (as Figure 5 shown).

[0040] Before cutting the turf, it is necessary to trim the degraded lawn and cut off the too-high grass leaves on the lawn to prevent the too-high grass leaves from covering the grass seeds and affecting the germination of the grass seeds.

[0041] Then, by setting the first driving mechanism, the second harrow floor 24 can be driven to reciprocate horizontally in the state where the first harrow floor 22 and the second harrow floor 24 are in contact with each other. Since the edges on both sides of the first harrow floor 22 and the second harrow floor 24 are blades, the second harrow floor 24 can cooperate with the first harrow floor 22 to form a mowing operation when moving horizontally back and forth, complete the mowing work, and cut off the too-high grass leaves on the lawn.

[0042] A matching component is arranged on the lower surface of the grass seed box 11.

[0043] By setting the matching component, the first harrow floor 22 and the second harrow floor 24 can rotate simultaneously in the state of being in contact with each other and cooperate with the grass seed box 11 to complete the seeding work.

[0044] As Figure 1 and Figure 2 and Figure 3 shown, the first driving mechanism includes first electric telescopic rods 31 fixed on the left and right side walls of the grass seed box 11. Both ends of the first electric telescopic rods 31 are bent, and the end far from the grass seed box 11 is fixedly connected with a rectangular bearing plate 32. A round shaft 33 is rotatably connected between the two rectangular bearing plates 32. The cylindrical roller 21 is sleeved on the round shaft 33, and the round shaft 33 is driven by an external motor.

[0045] Among them, the round shaft 33 can be driven by an external motor to rotate, driving the first harrow floor 22 to rotate simultaneously. The two first electric telescopic rods 31 can drive the cylindrical roller 21 to move vertically, so that the first harrow floor 22 and the second harrow floor 24 can rotate close to the turf to cut the turf, and can also move upward away from the turf.

[0046] AsFigure 3 and Figure 4 As shown in Figure 4 , on one side of the two rectangular bearing plates 32 close to each other, a first annular sleeve 34 is rotatably connected. Two symmetrically distributed second electric telescopic rods 35 are fixedly installed on the first annular sleeve 34. The ends of the two second electric telescopic rods 35 away from the first annular sleeve 34 are bent and fixedly connected to the same second annular sleeve 36. The round shaft 33 is located inside the second annular sleeve 36, and the strip plate 23 is fixed on the second annular sleeve 36.

[0047] Among them, the centers of the round shaft 33 and the first annular sleeve 34 are on the same horizontal line. By setting the second electric telescopic rod 35, the strip plate 23 and the second harrow floor 24 fixed on the strip plate 23 can be driven to move horizontally.

[0048] As Figure 3 shown in Figure 3 , the second driving mechanism includes a plurality of rectangular grooves 41 opened at both ends of the round shaft 33 and evenly distributed in a circumferential manner. A shaft sleeve 42 is sleeved on the round shaft 33, and a rectangular slider 43 slidably adapted to the rectangular groove 41 is integrally fixed on the inner wall of the shaft sleeve 42.

[0049] As Figure 3 shown in Figure 3 , a ratchet wheel 44 located inside the second annular sleeve 36 is sleeved on the shaft sleeve 42. Two symmetrically distributed limiting rods 45 are fixedly connected to opposite side walls of the second annular sleeve 36. The end of the limiting rod 45 away from the second annular sleeve 36 is L-shaped and fits on the surface of the ratchet wheel 44.

[0050] Adopting the above scheme, when the second annular sleeve 36 moves horizontally, the ratchet wheel 44 can be pushed to move horizontally along with it through the limiting rod 45, so that the ratchet wheel 44 is always inside the second annular sleeve 36. By setting the rectangular groove 41, the shaft sleeve 42 and the rectangular slider 43, the ratchet wheel 44 can move horizontally along the round shaft 33, and at the same time, it does not prevent the round shaft 33 from driving the ratchet wheel 44 to rotate. Since the end of the limiting rod 45 away from the second annular sleeve 36 only fits on the ratchet wheel 44, the limiting rod 45 does not prevent the ratchet wheel 44 from rotating either.

[0051] A ball is installed at the end of the limiting rod 45 away from the second annular sleeve 36, and the ball can reduce the friction between it and the limiting rod 45 when the ratchet wheel 44 rotates.

[0052] As Figure 6 shown in Figure 6 , at least one movable rod 46 penetrates through the second annular sleeve 36. One end of the movable rod 46 outside the second annular sleeve 36 is fixedly connected to a handle 47, and the other end of the movable rod 46 away from the handle 47 is fixedly connected to a ratchet tooth 48 meshing with the ratchet wheel 44. A first spring 49 sleeved on the movable rod 46 is fixedly connected to the ratchet tooth 48, and one end of the first spring 49 away from the ratchet tooth 48 abuts against the inner wall of the second annular sleeve 36.

[0053] When the ratchet tooth 48 is as Figure 6 shown, when the ratchet wheel 44 rotates in the direction indicated by the arrow D, the ratchet wheel 44 can drive the second annular sleeve 36 to rotate through the ratchet tooth 48. The second annular sleeve 36 can drive the second rake floor 24 to rotate through the strip plate 23. At the same time, the cylindrical roller 21 and the first rake floor 22 also rotate following the ratchet wheel 44 through the round shaft 33. Then the first rake floor 22 and the second rake floor 24 can be in a rotating state at the same time to cut the turf.

[0054] When the ratchet tooth 48 is as Figure 6 shown, when the ratchet wheel 44 rotates in the opposite direction of the arrow D, it cannot drive the second annular sleeve 36 to rotate through the ratchet tooth 48. Then the second annular sleeve 36, the strip plate 23 and the second rake floor 24 cannot rotate, while the cylindrical roller 21 and the first rake floor 22 rotate following the round shaft 33 and the ratchet wheel 44 in the opposite direction of the arrow D, so that the first rake floor 22 and the second rake floor 24 are in contact with each other, as Figure 5 shown.

[0055] By setting the two sides of the first rake floor 22 and the second rake floor 24 as blades, when the first rake floor 22 and the second rake floor 24 are in contact with each other, then by driving the second annular sleeve 36, the strip plate 23 and the second rake floor 24 to reciprocate horizontally through the second electric telescopic rod 35, at this time the first rake floor 22 and the second rake floor 24 can act as a lawn mowing tool to cut short the too-high grass leaves on the lawn, preventing the too-high grass leaves from covering the grass seeds and affecting the germination of the grass seeds.

[0056] Among them, the movable rod 46 can stretch in the second annular sleeve 36, and the movable rod 46 can rotate on the second annular sleeve 36.

[0057] As Figure 1 , Figure 7 , Figure 8 shown, the matching component includes arc-shaped grooves 51 opened on the opposite side walls of the grass seed box 11 and adapted to the cylindrical roller 21. The bottom plates 52 are telescopically inserted on the front and rear side walls of the grass seed box 11. One side of the two bottom plates 52 located inside the grass seed box 11 is fixedly connected with a movable strip 53.

[0058] As Figure 8 and Figure 7 shown, the lower surface of one movable strip 53 is inclined, the upper surface of the other movable strip 53 is inclined, and the two inclined surfaces are in a parallel state.

[0059] As Figure 9As shown, on one side outside the grass seed box 11, two bottom plates 52 are fixedly connected with bent bars 54. The free ends of the bent bars 54 are telescopically inserted with inserting rods 55. One end of the inserting rod 55 away from the bent bar 54 is fixedly connected to the outer side wall of the grass seed box 11. A second spring 56 sleeved on the inserting rod 55 is fixedly connected between the grass seed box 11 and the bent bar 54.

[0060] As Figure 1 and Figure 7 shown, a circular feeding port is opened on the upper surface of the grass seed box 11 for placing grass seeds into the grass seed box 11.

[0061] The working principle and usage process of the present invention:

[0062] In the initial state, each row of second harrow floors 24 is located between two rows of first harrow floors 22, and the state of the ratchet teeth 48 is as Figure 6 shown;

[0063] By driving the circular shaft 33 to rotate through an external motor, the circular shaft 33 can drive the cylindrical roller 21 sleeved on its surface to rotate accordingly. The cylindrical roller 21 can drive the first harrow floor 22 fixed on its surface to rotate accordingly. At the same time, the circular shaft 33 can drive the ratchet wheel 44 to rotate in the direction indicated by arrow D through the shaft sleeve 42. The ratchet wheel 44 can drive the second annular sleeve 36 to rotate through the ratchet teeth 48. The second annular sleeve 36 can drive the second harrow floor 24 to rotate through the strip plate 23. Then the first harrow floor 22 and the second harrow floor 24 can be in a rotating state at the same time to cut the turf.

[0064] Before cutting the turf, it is necessary to trim the degraded lawn and cut off the too-high grass leaves on the lawn to prevent the too-high grass leaves from covering the grass seeds and affecting the germination of the grass seeds.

[0065] When it is necessary to trim the grass leaves, drive the circular shaft 33 to rotate in the reverse direction through an external motor. The circular shaft 33 can drive the ratchet wheel 44 to rotate in the opposite direction of arrow D through the shaft sleeve 42. At this time, the ratchet wheel 44 cannot drive the second annular sleeve 36 to rotate through the ratchet teeth 48. Then the second annular sleeve 36, the strip plate 23 and the second harrow floor 24 cannot rotate, while the cylindrical roller 21 and the first harrow floor 22 rotate along the opposite direction of arrow D following the circular shaft 33 and the ratchet wheel 44, so that the first harrow floor 22 and the second harrow floor 24 are attached to each other.

[0066] Since the two sides of the first rake floor 22 and the second rake floor 24 are provided with blades, when the first rake floor 22 and the second rake floor 24 are fitted together, the second electric telescopic rod 35 is then used to drive the second annular sleeve 36, the strip plate 23 and the second rake floor 24 to reciprocate horizontally. At this time, the first rake floor 22 and the second rake floor 24 can act as a lawn mowing tool to cut short the overly long grass blades on the lawn, preventing the overly long grass blades from covering the grass seeds and affecting the germination of the grass seeds.

[0067] When the first rake floor 22 and the second rake floor 24 are in a fitted state, a row of the first rake floor 22 and a row of the second rake floor 24 will form a long strip-shaped arc plate;

[0068] When it is necessary to sow seeds on the cut turf, the first electric telescopic rod 31 is used to drive the rectangular carrier plate 32 to move upward. The rectangular carrier plate 32 can drive the cylindrical roller 21 to move upward accordingly, so that the cylindrical roller 21 moves into the arc groove 51. At the same time, the two movable strips 53 need to be pulled out of the seed box 11 to prevent the movable strips 53 from affecting the upward movement of the cylindrical roller 21;

[0069] The two movable strips 53 can continuously abut against the cylindrical roller 21 or the mutually fitted first rake floor 22 and second rake floor 24 when the cylindrical roller 21 rotates to prevent the grass seeds from falling.

[0070] The grass seeds are poured into the seed box 11 through the feeding port on the upper surface of the seed box 11. Then, the first rake floor 22 and the second rake floor 24 are driven to rotate simultaneously. During the rotation, the first rake floor 22 and the second rake floor 24 will push the inclined surface of the movable strip 53 to move the movable strip 53 outward of the seed box 11. Moreover, the first rake floor 22 and the second rake floor 24 can take the grass seeds in the seed box 11 out of the seed box 11 and scatter them on the lawn.

[0071] When it is necessary to sow grass seeds, the rotation directions of the first rake floor 22 and the second rake floor 24 are the directions indicated by the arrow D;

[0072] The mutually fitted first rake floor 22 and second rake floor 24 will scoop the grass seeds in the seed box 11 into them like a spoon during rotation, and take the scooped grass seeds out of the seed box 11 and scatter them on the lawn as they rotate;

[0073] Among them, the inclination angles of the inclined surfaces of the two movable strips 53 are adapted to the inclination angles of the first rake floor and the second rake floor, so that the first rake floor and the second rake floor can push the movable strip 53 during rotation and will not be stuck by the movable strip 53.

[0074] Among them, the ratchet 48 can be rotated by the handle 47 and the movable rod 46. After the ratchet 48 is rotated 180 degrees, when the ratchet wheel 44 rotates in the direction indicated by the arrow D, it cannot drive the second annular sleeve 36 to rotate through the ratchet 48. Then, the strip plate 23 and the second harrow floor 24 cannot rotate accordingly either. However, the cylindrical roller 21 and the first harrow floor 22 can follow the round shaft 33 and the ratchet wheel 44 to rotate in the direction indicated by the arrow D, separating the second harrow floor 24 and the first harrow floor 22 that are attached to each other.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
