Description

Technical Field

[0001] The invention relates to the technical field of ecological protection, and in particular to a grass seed sowing device for grassland ecological restoration. Background Art

[0002] The grass seed sowing device is a mechanized tool widely used for sowing grass seeds, such as lawn planting, greening projects, farmland restoration, and grassland green plant regeneration. The grass seed sowing device can be divided into two types: manual and mechanical. In order to make the grass seeds evenly sown, the existing Chinese patent with application number CN202220603235.X discloses a grass seed sowing device for grassland ecological restoration, including a vehicle body, a sowing mechanism is provided on the top of the vehicle body, and the sowing mechanism includes a tank body, which is fixed to the top of the vehicle body and connected to the inside of the vehicle body, a cover body is installed on the top of the tank body, a handle is fixed on the top of the cover body, and a first through-hole plate is sleeved on the inner wall of the bottom outlet of the tank body, and a second through-hole plate is attached to the bottom of the first through-hole plate.

[0003] This prior art controls the second port plate to rotate relative to the first port plate through a caster drive, so that material discharge is completed when their material holes overlap, and material discharge is stopped when their material holes are misaligned. Since the first port plate and the second port plate are in flat contact, when there are many grass seeds in the tank body, it will cause material squeezing at the bottom of the tank body. If the material discharge is only controlled by the rotational relationship between the two plates, problems such as grass seed jamming and material discharge difficulty may occur, and the grass seeds cannot be discharged evenly. Therefore, how to ensure smooth material discharge while combining caster drive is a problem that the current grass seed sowing equipment needs to solve. Summary of the invention

[0004] In order to solve the above problems, the present invention provides the following technical solutions:

[0005] The cam is provided with a driving member which has a bottom end portion for slitting the cam and a bottom end portion for sliding the cam into engagement with the cam.

[0006] As a further preferred embodiment, an arc-shaped surface is provided at the bottom of the barrel cavity, the bottom of the arc-shaped surface reaches the top of the movable hole, the bottom of the elastic plate reaches the movable hole along the arc-shaped surface and is connected to the top surface of the through-hole plate, the bottom of the elastic plate is close to the first material hole, and a circle of plastic deformation grooves is provided at the bottom of the driving seat, and the plastic deformation groove is a horn groove which gradually becomes larger from the top end to the bottom end.

[0007] As a further preferred embodiment, a plastic layer is provided on the top surface of the arc-shaped portion, the top surface of the plastic layer is arc-shaped, and the curvature of the arc-shaped portion is consistent with the curvature of the arc-shaped portion.

[0008] As a further preferred embodiment, a sinking cavity is opened at the bottom of the barrel, the opening of the sinking cavity faces downward, the driving seat is located in the sinking cavity, the bottom end of the sinking cavity is filled with a dividing plate, the middle part of the dividing plate is installed with a first guide seat, the driving rod is assembled in the first guide seat, and the crank-connecting rod structure is connected to the bottom end of the driving rod.

[0009] As further preferred, the driving seat is a rubber seat, the through-hole plate is a rubber plate, and the bottom surface of the through-hole plate is convex in a downward arc shape facing the plastic layer.

[0010] As a further preferred embodiment, a second discharge hole is provided on the dividing plate, and the top surface of the dividing plate is an inclined surface, and the inclined direction gradually inclines downward toward the direction of the first guide seat.

[0011] As a further preferred embodiment, the elastic plate is a fan-shaped plate which gradually widens from one end of the first material hole to the other end, there are a plurality of first material holes, and the elastic plates are a plurality of pieces, and a plurality of pieces of the elastic plates are arranged on the through-port plate corresponding to one first material hole, and a movable gap is left between the two elastic plates, and a plurality of flow channels are opened on the arc surface at the bottom of the barrel cavity along the arc direction of the arc surface, and each piece of the elastic plate is correspondingly arranged on one of the flow channels and covers the flow channel, and rounded surfaces are provided between the two sides of the flow channel and the arc surface, and the rounded surfaces have a smooth transition to the flow channel.

[0012] As a further preferred embodiment, the crank-connecting rod structure includes a crank-connecting rod hinged on one of the casters, a driven frame connected to the crank-connecting rod, a spring seat connected between the driven frame and the bottom surface of the barrel, and a second guide seat fixed to the vehicle body, and the crank-connecting rod slides in the second guide seat.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] A crank connecting rod structure is arranged on the caster, and a lifting port plate is arranged at the bottom of the barrel, and the other end of the crank connecting rod mechanism is connected to the port plate. When in use, the rotating action generated by the caster is transmitted to the port plate by the crank connecting rod mechanism, and the lifting and lowering of the port plate is controlled. A circle of elastic plates is arranged in the barrel, and the top surface of the port plate is connected to the bottom end of the elastic plate. When the driving seat rises, all the elastic plates bend in the direction away from the barrel surface, and these elastic plates and the port plate push the grass seeds to rise by a certain amplitude. At the same time, these elastic plates will continue to bend in their arc direction, giving These grass seeds on the elastic plate provide an upward and central area force, forcing the grass seeds to move upward first in the barrel. As the crank connecting rod rotates rapidly to the next position, the driven frame drives the driving rod to descend, the driving rod drives the driving seat, and the driving seat drives the plastic layer to descend. As the driving rod continues to descend, the vibration effect generated by the rapid descent of the through-hole plate and the rapid recovery of the elastic plate causes the grass seeds to fall back quickly by inertia. The inertial force and the vibration effect generated are used to quickly discharge the grass seeds through the first material hole. In this way, the barrel can be prevented from getting stuck.

DETAILED DESCRIPTION

[0022] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0023] In one embodiment, Figure 1-Figure 6 As shown: This embodiment provides a grass seed sowing device for grassland ecological restoration, including a barrel 1, a barrel 1 and a driving assembly 4. A body 2 is provided at the bottom of the barrel 1, and a caster 3 is provided on the body 2. A driving assembly 4 is provided at the bottom of the barrel 1. A movable hole 5 is opened at the bottom end of the barrel 1. The driving assembly 4 includes a through-hole plate 6 sliding in the movable hole 5, and a first material hole 7 is provided on the through-hole plate 6. The driving assembly 4 also includes a driving seat 8 arranged at the bottom of the barrel 1, and a driving rod 9 is provided at the bottom of the driving seat 8. The driving seat 8 is located below the through-hole plate 6. The driving assembly 4 includes a crank connecting rod structure 10 connected to the caster 3, and the other end of the crank connecting rod structure 10 is connected to the driving rod 9. The driving assembly 4 also includes an elastic plate 11 arranged on the cavity wall of the barrel 1, and the bottom end of the elastic plate 11 reaches the movable hole 5 and is connected to the through-hole plate 6, and the top end of the elastic plate 11 reaches the barrel mouth of the barrel 1 and is connected to the barrel mouth. The top surface of the driving seat 8 is provided with an arc-shaped portion 81 protruding upward. When the driving rod 9 rises under the drive of the crank-connecting rod structure 10, it will bring the driving seat 8 up with it. The driving seat 8 will push the arc portion 81 against the through-hole plate 6 to make the through-hole plate 6 rise, and the through-hole plate 6 will drive the elastic plate 11 to continue to bend in the bending direction (first bend in the axial direction and then bend upward). The rise of the driving seat 8 and the bending of the elastic plate 11 give the grass seeds a pre-stress, and the driving rod 9 will generate inertia when bringing the driving seat 8 down. When the driving seat 8 drives the elastic plate 11 to recover, the elastic plate 11 will fit onto the barrel 1 again. The two actions together produce a vibration effect, which makes it smoother for the grass seeds to be discharged through the first material hole 7.

[0024] As a further preferred embodiment, the crank-connecting rod structure 10 includes a crank-connecting rod 22 hinged on a caster 3, a driven frame 23 connected to the crank-connecting rod 22, a spring seat 24 connected between the driven frame 23 and the bottom surface of the barrel 1, and a second guide seat 25 fixed on the vehicle body 2, and the crank-connecting rod 22 slides in the second guide seat 25.

[0025] Working principle and effect: When in use, put grass seeds into the barrel 1, and the vehicle body 2 drives the caster 3 to rotate when moving forward, and the caster 3 drives the crank connecting rod 22 to move, and the crank connecting rod 22 drives the driven frame 23 to move, and the driven frame 23 drives the driving rod 9 to move up and down, and the driving rod 9 drives the driving seat 8 to move up and down, and the driving seat 8 moves the plastic layer 13 up and down. When the driving seat 8 rises with the plastic layer 13, the plastic layer 13 will enter the movable hole 5 and push the through plate 6 to rise along the movable hole 5, and the through plate 6 pushes all the elastic plates 11, so that all The elastic plates 11 bend upward away from the arc surface 12, and the grass seeds are pushed up by these elastic plates 11 and the through-hole plate 6. At the same time, the elastic plates 11 will continue to bend in the direction of their arc, providing an upward and central area force to the grass seeds on the elastic plates 11, forcing the grass seeds to move upward first in the barrel 1, especially the grass seeds close to the through-hole plate 6 (it can be regarded as the grass seeds being pounded upward once). At this time, the plastic layer 13 is compressed on the bottom surface of the through-hole plate 6 and all the first material holes 7 on the through-hole plate 6 are closed. As the crank connecting rod 22 rotates rapidly to the next position, the driven frame 23 drives the driving rod 9 to descend, the driving rod 9 drives the driving seat 8, and the driving seat 8 drives the plastic layer 13 to descend. As the driving rod 9 continues to descend, the distance between the plastic layer 13 and the through-hole plate 6 becomes farther, the first material hole 7 opens rapidly, and the through-hole plate 6 descends rapidly along the movable hole 5, the plastic layer 13 expands back to its original state, and the top surface of the plastic layer 13 recovers to an arc shape. The driving seat 8 descends rapidly, and the elastic plate 11 recovers rapidly and quickly hits the arc surface 12 by rebounding. The vibration effect generated by the rapid descent of the through-hole plate 6 and the rapid recovery of the elastic plate 11 causes the grass seeds to fall back quickly by inertia. The inertial force and the vibration effect generated are used to allow the grass seeds to be discharged quickly through the first material hole 7, and the barrel 1 avoids material jamming when sowing seeds.

[0026] In addition, after the plastic layer 13 expands back to its original shape, its top surface returns to an arc shape. At this time, its arc-shaped top surface is just located on the bottom side of the through-hole plate 6, which also corresponds to the bottom side of the first material hole 7. After the grass seeds are discharged through the first material hole 7, even if they fall on the plastic layer 13, there will be no material stagnation.

[0027] In terms of structure, even if the present invention also uses casters 3 as a drive like the prior art, the mechanism combined with casters 3 uses a crank-connecting rod mechanism, and the crank-connecting rod mechanism transmits power to the drive seat 8 in an up-and-down motion, which assists in the discharge of the barrel 1 without the occurrence of material jamming. It does not need to be driven by gears like the prior art, and does not require high assembly relations like gear transmission during assembly, and does not require gear selection. The crank-connecting rod mechanism can be made from local materials, for example, the crank-connecting rod mechanism can be made by welding and articulation, which is low in cost. The lifting action of the drive seat 8 is combined with a plurality of elastic plates 11, and the action is transmitted to the barrel 1 by these elastic plates 11. When the drive seat 8 rises, it directly participates in the barrel 1, so that these elastic plates 11 bend toward the axial direction, cooperate with the rise of the drive seat 8, and provide an upward pre-stress to the grass seeds. The vibration effect generated when the drive seat 8 falls back and these elastic plates 11 are restored and reset assists in the smooth discharge of the grass seeds.

[0028] like Figure 1 , Figure 2 As shown, the bottom of the barrel cavity of the barrel 1 is provided with an arc surface 12, the bottom of the arc surface 12 reaches the top of the movable hole 5, the bottom of the elastic plate 11 reaches the movable hole 5 along the arc surface 12 and is connected to the top surface of the port plate 6. When the port plate 6 rises, it drives the elastic plate 11 to bend upward. The elastic plate 11 uses its arc structure to achieve a better bending effect, and at the same time, combined with the arc surface 12 of the barrel 1, the discharge efficiency of the barrel 1 is improved. Figure 1 , Figure 2 As shown, a circle of plastic deformation grooves 18 are formed at the bottom of the driving seat 8, and the plastic deformation grooves 18 are horn grooves that gradually expand from the top to the bottom. The top surface of the driving seat 8 is against the through-hole plate 6. When the through-hole plate 6 is pushed upward, the driving seat 8 will deform downward with the plastic deformation grooves 18 as the plastic point, so as to enter the movable hole 5 and continue to push the through-hole plate 6 upward.

[0029] like Figure 1 As shown, a sinking cavity 14 is provided at the bottom of the barrel 1, and the opening of the sinking cavity 14 faces downward. The driving seat 8 is located in the sinking cavity 14, and the bottom end of the sinking cavity 14 is filled with a dividing plate 15. The dividing plate 15 is provided with a second discharge hole 17. The top surface of the dividing plate 15 is an inclined surface, and the inclined direction gradually tilts downward toward the direction of the first guide seat 16. The first guide seat 16 is installed in the middle of the dividing plate 15, and the driving rod 9 is assembled in the first guide seat 16. The crank connecting rod structure 10 is connected to the bottom end of the driving rod 9. The setting of the sinking cavity 14 allows the driving seat 8 to be assembled in a relatively sealed environment, which can cope with harsh production environments and also saves assembly space. Figure 1 , Figure 5As shown, the grass seeds fall into the sink cavity 14 and then fall on the dividing plate 15. After being guided by the inclined surface of the dividing plate 15 and divided by a large number of second discharge holes 17, the grass seeds are evenly spread outward.

[0030] like Figure 1 , Figure 2 As shown, the driving seat 8 is a rubber seat and the through-hole plate 6 is a rubber plate. The grass seeds will not be damaged when they are received. The bottom surface of the through-hole plate 6 is convex in a downward arc toward the plastic layer 13. After the grass seeds fall onto the plastic layer 13, they continue to be discharged downward through the arc surface of the plastic layer 13 to avoid material stagnation.

[0031] like Figure 4 , Figure 6 As shown, the elastic plate 11 is a fan-shaped plate that gradually widens from one end of the first material hole 7 to the other end. There are a plurality of first material holes 7, and a plurality of elastic plates 11. A plurality of elastic plates 11 are arranged on the port plate 6 corresponding to one first material hole 7. A movable gap 19 is left between the two elastic plates 11. A plurality of flow channels 20 are opened on the arc surface 12 at the bottom of the barrel 1 along the arc direction of the arc surface 12. Each elastic plate 11 is correspondingly arranged on a flow channel 20 and covers the flow channel 20. A fillet surface 21 is arranged between the two sides of the flow channel 20 and the arc surface 12, and the fillet surface 21 smoothly transitions toward the flow channel 20. When these elastic plates 11 continue to bend in their bending direction under the push of the port plate 6, the movable gap 19 between them ensures that they bend smoothly and avoids dead points when bending. However, it is inevitable that grass seeds will pass through the active gap 19 and enter the curved surface 12. When the elastic plate 11 returns to its original position, these grass seeds will be squeezed and damaged. Therefore, a plurality of flow channels 20 are provided on the curved surface 12, and each flow channel 20 corresponds to the inner side of an elastic plate 11. When the elastic plate 11 is bent, even if some grass seeds pass through the active gap 19 and enter the curved surface 12, they will not only be discharged toward the port plate 6 through the curved surface 12, but also enter the flow channel 20 from the rounded surface 21. 0, and discharged into the corresponding first material hole 7 through the flow channel 20, and released downward through the first material hole 7. It can be seen that the bending action of the elastic plate 11 not only provides a pre-force to the grass seeds, but also when providing the pre-force, a part of the seeds will pass through the active gap 19 and the flow channel 20 into the port plate 6, and then be discharged downward through the first material hole 7 on the port plate 6, which plays a role in loosening and discharging the grass seeds. This effect can also solve the problem of sticking due to the high bottom pressure when the grass seeds are discharged.
