Description

Technical Field

[0001] The invention belongs to the technical field of sowing, in particular to a turf-scratching seeder. Background Art

[0002] Scratch seeding is a method of overseeding a lawn that is used to reseed sparse areas, fill in bald spots or thin sections of a lawn, or to improve the density and quality of a lawn without completely renovating it.

[0003] The traditional way is to use tools to scratch the turf first, such as using a rake to make shallow grooves or small holes in the existing turf. The main purpose is to break the dead grass layer on the surface of the lawn so that the seeds can contact the soil. This is because the dead leaves form a solid hydrophobic layer on the surface of the lawn. If the dead grass layer is not handled properly, the grass seeds after sowing will not only easily dehydrate and die, but the roots will also find it difficult to penetrate the dead grass layer and penetrate into the soil.

[0004] Then evenly spread the grass seeds on the scratched turf, making sure the seeds fall into the scratches or holes and come into contact with the soil. Next, lightly cover the soil and compact it to help the seeds combine closely with the soil and promote germination. Finally, water it appropriately to keep the soil moist, but avoid over-watering that may cause seed loss.

[0005] However, the working process of this method is relatively complicated, and different tools and machines need to be used. It is necessary to use a rake to scratch the turf first, and then replace the seeder to sow the seeds.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, the present invention provides a turf scratching seeder, comprising a grass seed box 11, and movable 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.

[0022] The armrest 13 enables the planter to control the overall moving direction of the seeder, while the moving roller 12 enables the seeder to be conveniently moved to a sparsely-spaced lawn area.

[0023] like Figure 1 and Figure 2 As shown, a cylindrical roller 21 is provided under the grass seed box 11, and a plurality of rows of first raking floors 22 are integrally fixed on the surface of the cylindrical roller 21, and the plurality of rows of first raking floors 22 are equidistantly distributed on the cylindrical roller 21 in a circle, and a strip plate 23 is provided between two adjacent rows of the first raking floors 22, and the strip plate 23 is attached to the surface of the cylindrical roller 21, and a plurality of equidistantly distributed second raking floors 24 are provided on each strip plate 23.

[0024] The first rake floor 22 and the second rake floor 24 are used to scratch the grass. When the first rake floor 22 and the second rake floor 24 are in a rotating state at the same time, and the first rake floor 22 and the second rake floor 24 can contact the lawn during rotation, the first rake floor 22 and the second rake floor 24 can act as a rake to scratch the grass.

[0025] The edges of both sides of the first raking floor 22 and the second raking floor 24 are provided with blades, and a first driving mechanism for driving the strip plate 23 and the second raking floor 24 to move in the horizontal direction and a second driving mechanism for driving the first raking floor 22 and the second raking floor 24 to rotate are arranged under the grass seed box 11.

[0026] By providing a second driving mechanism, the first raking floor 22 and the second raking floor 24 can be driven to rotate at the same time to complete the turf scratching work; The second driving mechanism can also independently drive the first rake floor 22 to rotate, so that the first rake floor 22 can be attached to the second rake floor 24 (such as Figure 5 shown); Before scratching the turf, the degraded lawn needs to be trimmed and the tall grass leaves on the lawn need to be trimmed to prevent the tall grass leaves from covering the grass seeds and affecting the germination of the grass seeds. Then, by providing the first driving mechanism, the second raking floor 24 can be driven to reciprocate in the horizontal direction when the first raking floor 22 and the second raking floor 24 are in contact with each other. Since the edges of both sides of the first raking floor 22 and the second raking floor 24 are blades, the second raking floor 24 can cooperate with the first raking floor 22 to perform a mowing operation when moving horizontally back and forth, thereby completing the mowing operation and trimming off the excessively high grass leaves on the lawn.

[0027] The lower surface of the grass seed box 11 is provided with matching components.

[0028] By providing the matching components, the first raking floor plate 22 and the second raking floor plate 24 can rotate simultaneously in a state of being in contact with each other, and cooperate with the grass seed box 11 to complete the sowing work.

[0029] like Figure 1 and Figure 2 and Figure 3 As shown, the first driving mechanism includes a first electric telescopic rod 31 fixed on the left and right side walls of the grass seed box 11, both ends of the first electric telescopic rod 31 are bent, and the end away from the grass seed box 11 is fixedly connected to a rectangular supporting plate 32, and a circular shaft 33 is rotatably connected between the two rectangular supporting plates 32, the cylindrical roller 21 is sleeved on the circular shaft 33, and the circular shaft 33 is driven by an external motor.

[0030] The circular shaft 33 can be driven to rotate by an external motor, driving the first raking floor 22 to rotate simultaneously. The two first electric telescopic rods 31 can drive the cylindrical roller 21 to move in the vertical direction, so that the first raking floor 22 and the second raking floor 24 can rotate close to the turf to scratch the turf, and can also move upward away from the turf.

[0031] like Figure 3 and Figure 4As shown, the two rectangular supporting plates 32 are rotatably connected to the first annular sleeve 34 on one side close to each other, and 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 in the second annular sleeve 36, and the strip plate 23 is fixed on the second annular sleeve 36.

[0032] The centers of the circular shaft 33 and the first annular sleeve 34 are on the same horizontal line. By providing the second electric telescopic rod 35 , the strip plate 23 and the second raking floor plate 24 fixed on the strip plate 23 can be driven to move in the horizontal direction.

[0033] like Figure 3 As shown, the second driving mechanism includes a plurality of rectangular grooves 41 opened at both ends of the circular shaft 33 and distributed equidistantly around the circumference. A shaft sleeve 42 is sleeved on the circular shaft 33 , and a rectangular slider 43 slidably matched with the rectangular groove 41 is integrally fixed to the inner wall of the shaft sleeve 42 .

[0034] like Figure 3 As shown, a ratchet 44 located in the second annular sleeve 36 is sleeved on the shaft sleeve 42, and two symmetrically distributed limiting rods 45 are fixedly connected to the 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 44.

[0035] By adopting the above scheme, when the second annular sleeve 36 moves in the horizontal direction, the limiting rod 45 can push the ratchet 44 to move in the horizontal direction, so that the ratchet 44 is always in the second annular sleeve 36. By providing the rectangular groove 41, the shaft sleeve 42 and the rectangular slider 43, the ratchet 44 can move horizontally along the circular shaft 33 without hindering the circular shaft 33 from driving the ratchet 44 to rotate. Since the end of the limiting rod 45 away from the second annular sleeve 36 is only attached to the ratchet 44, the limiting rod 45 will not hinder the rotation of the ratchet 44.

[0036] A ball is installed at one end of the limiting rod 45 away from the second annular sleeve 36 , and the ball can reduce the friction between the limiting rod 45 and the limiting rod 45 when the ratchet wheel 44 rotates.

[0037] like Figure 6 As shown, at least one movable rod 46 passes through the second annular sleeve 36, and one end of the movable rod 46 located outside the second annular sleeve 36 is fixedly connected to a handle 47, and the end of the movable rod 46 away from the handle 47 is fixedly connected to a ratchet 48 meshing with the ratchet 44, and the ratchet 48 is fixedly connected to a first spring 49 sleeved on the movable rod 46, and the end of the first spring 49 away from the ratchet 48 rests on the inner wall of the second annular sleeve 36.

[0038] When the ratchet 48 is Figure 6In the state, when the ratchet 44 rotates in the direction indicated by the arrow D, the ratchet 44 can drive the second annular sleeve 36 to rotate through the ratchet teeth 48, and 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 with the ratchet 44 through the circular shaft 33, so that the first rake floor 22 and the second rake floor 24 can be in a rotating state at the same time to scratch the turf.

[0039] When the ratchet 48 is Figure 6 In this state, when the ratchet 44 rotates in the opposite direction of the arrow D, the second annular sleeve 36 cannot be driven to rotate by the ratchet teeth 48, so the second annular sleeve 36, the strip plate 23 and the second rake plate 24 cannot rotate, and the cylindrical roller 21 and the first rake plate 22 follow the circular shaft 33 and the ratchet 44 to rotate in the opposite direction of the arrow D, so that the first rake plate 22 and the second rake plate 24 fit together, as shown in FIG. Figure 5 shown.

[0040] By providing blades on both sides of the first raking floor 22 and the second raking floor 24, when the first raking floor 22 and the second raking floor 24 are fitted together, the second annular sleeve 36, the strip plate 23 and the second raking floor 24 are driven by the second electric telescopic rod 35 to reciprocate in the horizontal direction. At this time, the first raking floor 22 and the second raking floor 24 can act as tools for mowing the lawn, cutting short the excessively high grass leaves on the lawn, and preventing the excessively high grass leaves from covering the grass seeds and affecting the germination of the grass seeds.

[0041] The movable rod 46 can be extended and retracted in the second annular sleeve 36 , and the movable rod 46 can be rotated on the second annular sleeve 36 .

[0042] like Figure 1 , Figure 7 , Figure 8 As shown, the matching component includes an arc groove 51 opened on the opposite side walls of the grass seed box 11 and adapted to the cylindrical roller 21, and a bottom plate 52 is telescopically inserted on the front and rear side walls of the grass seed box 11. The two bottom plates 52 are located on one side of the interior of the grass seed box 11 and are fixedly connected with a movable bar 53.

[0043] like Figure 8 and Figure 7 As shown, the lower surface of one of the movable bars 53 is inclined, the upper surface of the other movable bar 53 is inclined, and the two inclined surfaces are parallel to each other.

[0044] like Fig. 9As shown, the two bottom plates 52 are fixedly connected to one side outside the grass seed box 11 with a bending rod 54, and the free end of the bending rod 54 is telescopically inserted with an insertion rod 55, and one end of the insertion rod 55 away from the bending rod 54 is fixedly connected to the outer wall of the grass seed box 11, and a second spring 56 mounted on the insertion rod 55 is fixedly connected between the grass seed box 11 and the bending rod 54.

[0045] like Figure 1 and Figure 7 As shown, a circular feeding port is provided on the upper surface of the grass seed box 11 for placing grass seeds into the grass seed box 11 .

[0046] The working principle and use process of the present invention: In the initial state, each row of second rake plates 24 is located between two rows of first rake plates 22, and the state of the ratchet teeth 48 is as follows: Figure 6 As shown; The circular shaft 33 is driven to rotate by an external motor, and the circular shaft 33 can drive the cylindrical roller 21 sleeved on its surface to rotate accordingly, and the cylindrical roller 21 can drive the first rake floor 22 fixed on its surface to rotate accordingly. At the same time, the circular shaft 33 can drive the ratchet 44 to rotate in the direction indicated by the arrow D through the shaft sleeve 42, and the ratchet 44 can drive the second annular sleeve 36 to rotate accordingly through the ratchet teeth 48, and the second annular sleeve 36 can drive the second rake floor 24 to rotate accordingly through the strip plate 23, so that the first rake floor 22 and the second rake floor 24 can be in a rotating state at the same time to scratch the turf.

[0047] Before scratching the turf, the degraded lawn needs to be trimmed and the grass leaves that are too high on the lawn need to be trimmed to prevent the high grass leaves from covering the grass seeds and affecting the germination of the grass seeds.

[0048] When it is necessary to trim the grass leaves, the circular shaft 33 is driven to rotate in the opposite direction by an external motor, and the circular shaft 33 can drive the ratchet 44 to rotate in the opposite direction of the arrow D through the shaft sleeve 42. At this time, the ratchet 44 cannot drive the second annular sleeve 36 to rotate through the ratchet teeth 48, so that the second annular sleeve 36, the strip plate 23 and the second rake floor 24 cannot rotate, and the cylindrical roller 21 and the first rake floor 22 follow the circular shaft 33 and the ratchet 44 to rotate in the opposite direction of the arrow D, so that the first rake floor 22 and the second rake floor 24 fit together.

[0049] Since blades are arranged on both sides of the first raking floor 22 and the second raking floor 24, when the first raking floor 22 and the second raking floor 24 are fitted together, the second annular sleeve 36, the strip plate 23 and the second raking floor 24 are driven by the second electric telescopic rod 35 to reciprocate in the horizontal direction. At this time, the first raking floor 22 and the second raking floor 24 can act as a mowing tool to cut short the excessively high grass leaves on the lawn to prevent the excessively high grass leaves from covering the grass seeds and affecting the germination of the grass seeds.

[0050] When the first rake floor panels 22 and the second rake floor panels 24 are in a state of being in contact with each other, a row of the first rake floor panels 22 and a row of the second rake floor panels 24 will form a long arc-shaped plate; When it is necessary to sow the scratched turf, the rectangular carrying plate 32 is driven to move upward by the first electric telescopic rod 31, and the rectangular carrying plate 32 can drive the cylindrical roller 21 to move upward accordingly, so that the cylindrical roller 21 moves into the arc groove 51, and at the same time, the two movable bars 53 are pulled out of the grass seed box 11 to prevent the movable bars 53 from affecting the upward movement of the cylindrical roller 21; The two movable bars 53 can continuously press against the cylindrical roller 21 or the first raking plate 22 and the second raking plate 24 that are in contact with each other to prevent the grass seeds from falling when the cylindrical roller 21 rotates.

[0051] The grass seeds are poured into the grass seed box 11 through the feeding port on the upper surface of the grass seed box 11, and then the first raking floor 22 and the second raking floor 24 are driven to rotate simultaneously. The first raking floor 22 and the second raking floor 24 will push the inclined surface of the movable bar 53 during the rotation to move the movable bar 53 to the outside of the grass seed box 11, and the first raking floor 22 and the second raking floor 24 can bring the grass seeds in the grass seed box 11 out of the grass seed box 11 and sow them on the lawn.

[0052] When it is necessary to sow grass seeds, the first rake floor 22 and the second rake floor 24 rotate in the direction indicated by arrow D; The first raking floor plate 22 and the second raking floor plate 24 that fit each other will scoop the grass seeds in the grass seed box 11 into the first raking floor plate 22 and the second raking floor plate 24 during rotation, and as the first raking floor plate 22 and the second raking floor plate 24 rotate, the grass seeds scooped therein are taken out of the grass seed box 11 and spread on the lawn. The inclination angles of the inclined surfaces of the two movable bars 53 match the inclination angles of the first raking plate and the second raking plate, so that the first raking plate and the second raking plate can push the movable bars 53 when rotating and will not be stuck by the movable bars 53.

[0053] The ratchet 48 can be rotated by the handle 47 and the movable rod 46. After the ratchet 48 is rotated 180 degrees, the ratchet 44 cannot drive the second annular sleeve 36 to rotate through the ratchet 48 when rotating in the direction indicated by the arrow D, and the strip plate 23 and the second rake floor 24 cannot rotate accordingly. However, the cylindrical roller 21 and the first rake floor 22 can rotate along with the circular shaft 33 and the ratchet 44 in the direction indicated by the arrow D, so that the second rake floor 24 and the first rake floor 22 that are stuck together can be separated.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
