Description

Technical Field

[0001] The present application relates to the technical field of planting equipment, and in particular to a lawn planting device. Background Art

[0002] Grassland is land that mainly grows herbs and shrubs and is suitable for the development of animal husbandry production. It has a subtle influence on the living environment of human beings. Before planting grassland, the soil needs to be loosened to have good air permeability to facilitate the smooth germination of grass seeds after sowing. In the prior art, before loosening the soil, relevant machinery is usually used to assist.

[0003] The Chinese patent with the authorization announcement number CN215935484U discloses a grassland soil loosening device, including a mounting plate, a mounting frame is arranged at one end of the mounting plate, and two sets of loosening wheels are arranged in the mounting frame; the two sets of loosening wheels are connected to the mounting plate through a transmission assembly, and the outer circumference of the two sets of loosening wheels are provided with multiple sets of loosening teeth. When the loosening wheels rotate, the soil is loosened by the multiple sets of loosening teeth, which can make the soil loosening more efficient.

[0004] Regarding the above-mentioned related technical solutions, based on the sowing density of grass seeds, when the density of grass seeds sown per unit area is relatively large, the requirements for soil looseness and soil permeability are higher, and it is often necessary to loosen the soil at a deeper depth; however, the positions of the loosening wheel and the mounting plate in the above-mentioned device are fixed, and a loosening device with a loosening wheel of a larger size is required to loosen the soil at a deeper depth, which is inconvenient to use. Utility Model Content

[0005] In order to conveniently loosen the soil at a deeper level, the present application provides a grass planting device.

[0006] The present application provides a lawn planting device that adopts the following technical solution:

[0007] A lawn planting device comprises a device assembly, wherein a mounting bracket is rotatably mounted at the front end of the device assembly, and the mounting bracket is provided with a loosening mechanism for loosening soil; the mounting bracket is rotatably connected to a connecting arm plate, and the connecting arm plate is provided with a plurality of positioning holes, and all the positioning holes are arranged at intervals along the length direction of the connecting arm plate; a positioning column is fixed to the side of the device assembly, the positioning column is plug-fitted with the positioning hole, and a limiting component for limiting the connection arm plate from being separated from the positioning column is detachably mounted at the end of the positioning column.

[0008] By adopting the above technical solution, by providing a mounting bracket that is rotatably mounted on the device assembly, and by plugging and matching between the positioning hole of the connecting arm plate and the positioning column, the rotation position of the mounting bracket can be positioned, and the soil can be loosened by the loosening mechanism. In addition, by removing the limiting component, separating the connecting arm plate from the positioning column, and inserting another positioning hole of the connecting arm plate into the positioning column, the mounting bracket can be rotated relative to the device assembly, and the position of the mounting bracket and the device assembly is changed, thereby adjusting the height of the loosening mechanism, and the soil at a deeper depth can be loosened conveniently to ensure the smooth germination and growth of grass seeds after sowing.

[0009] Optionally, the mounting bracket is fixed with an articulated seat, which includes two side panels arranged at intervals, and a connecting arm plate is rotatably connected between the two side panels via a rotating shaft. The width of the connecting arm plate is smaller than the spacing between the two side panels. When the connecting arm plate moves in a direction away from the device assembly, the connecting arm plate can detach from the positioning column.

[0010] By adopting the above-mentioned technical solution, a hinge seat is set to rotatably install the connecting arm plate, and the width of the connecting arm plate is smaller than the spacing between the two side plates, so that the connecting arm plate can slide along the axial direction of the rotating shaft, and when the connecting arm plate moves to a position away from the device assembly, the connecting arm plate can smoothly disengage from the positioning column, so as to change the position of the positioning column and the corresponding plug-in positioning hole, thereby playing a role in adjusting the height of the loosening mechanism.

[0011] Optionally, the side panel farther away from the device assembly among the two side panels is set as the first side panel, and a magnetic attraction component is provided between the connecting arm plate and the first side panel. When the limiting component is detached from the positioning column, the connecting arm plate and the first side panel are abutted against each other through the magnetic attraction component, and the positioning hole automatically detaches from the positioning column.

[0012] By adopting the above-mentioned technical solution and setting up a magnetic suction component, the connecting arm plate can always have a tendency to approach the first side plate. After the limiting component is removed from the positioning column, the connecting arm plate can automatically move outward under the action of the magnetic suction component until it is in contact with the first side plate. At this time, the positioning hole automatically disengages from the positioning column, that is, the connecting arm plate automatically disengages from the positioning column, which can facilitate the operator to perform height adjustment operations on the loosening mechanism.

[0013] Optionally, the magnetic attraction component includes a magnetic block embedded in the side of the connecting arm plate close to the first side plate and a magnetic ring embedded in the side of the first side plate close to the connecting arm plate, and the magnetic block and the magnetic ring are magnetically attracted to each other.

[0014] By adopting the above technical solution, through the magnetic attraction between the magnetic block and the magnetic ring, the connecting arm plate can automatically approach and fit to the first side plate after the limiting component is removed, so that the operator can adjust the height of the loosening mechanism.

[0015] Optionally, the limiting component is configured as a screw cap, and a plurality of structural grooves for holding are evenly distributed on the outer circumference of the screw cap; the outer diameter of the screw cap is larger than the outer diameter of the positioning column, and the end face of the screw cap is provided with a threaded groove for connecting with the positioning column.

[0016] By adopting the above-mentioned technical solution, the setting of the structural groove can facilitate the operator to hold and rotate the screw cap. After adjusting the connecting arm plate so that one of the positioning holes of the connecting arm plate is directly opposite to the positioning column, by making the screw cap abut against the connecting arm plate and rotating the screw cap to be threadedly connected with the positioning column, the connecting arm plate and the positioning column can be kept in a matched limit position, thereby reducing the occurrence of the connecting arm plate directly separating from the positioning column.

[0017] Optionally, the loosening mechanism includes a roller shaft rotatably connected to the mounting bracket and a plurality of loosening wheels spaced apart along the center axis of the roller shaft, and a plurality of soil turning hooks are equidistantly arranged on the outer peripheral surface of each loosening wheel.

[0018] By adopting the above technical solution, by setting a freely rotating roller shaft, the device assembly can drive the roller shaft to rotate circumferentially when it moves, and by setting a plurality of loosening wheels, when the roller shaft rotates, the soil turning hooks on the outer surface of the loosening wheel can smoothly turn the soil to loosen the soil.

[0019] Optionally, the device assembly is provided with a punching mechanism, which is located at the rear end of the loosening mechanism along the moving direction of the device assembly; wherein the punching mechanism includes a lifting base slidably connected to the device assembly, a plurality of hole nails arranged at the bottom of the lifting base, and a driving assembly for driving the lifting base to rise and fall.

[0020] By adopting the above-mentioned technical solution, after the loosening mechanism loosens the soil, the driving mechanism can drive the lifting base to move up and down, forcing the hole nails at the bottom of the lifting base to be inserted into the loose soil holes, so that the soil forms a plurality of air holes distributed at intervals, so as to further enhance the air permeability of the soil and facilitate the germination and growth of grass seeds after sowing.

[0021] Optionally, the device assembly is fixed with a fixed bracket, and the driving component includes an eccentric wheel rotatably mounted on the fixed bracket and a rotating motor for driving the eccentric wheel to rotate, and the eccentric wheel and the fixed bracket are eccentrically connected; an elastic member is also provided between the lifting base and the device assembly, and the elastic member is used to force the lifting base to normally rest against the eccentric wheel.

[0022] By adopting the above technical solution, the lifting base can be normally against the eccentric wheel by arranging an elastic member, and the eccentric wheel is driven to rotate eccentrically by arranging a rotating motor. The distance between the outer edge of the eccentric wheel and the rotating axis of the eccentric wheel is constantly changed, thereby being able to push the lifting base up and down, so that the hole nails can be inserted into the soil to form air holes.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a plurality of positioning holes, changing the positioning hole corresponding to the positioning column, that is, the plug-in column is inserted into another positioning hole of the connecting arm plate, the height of the loosening mechanism can be adjusted, and the soil at a deeper depth can be loosened conveniently to ensure the smooth germination and growth of grass seeds after sowing;

[0025] 2. By setting a magnetic attraction component, when the limiting component is removed from the positioning column, the connecting arm plate can automatically move outward to fit with the first side plate under the action of the magnetic attraction component. At this time, the connecting arm plate automatically separates from the positioning column, which can facilitate the operator to adjust the height of the loosening mechanism;

[0026] 3. After the loosening mechanism loosens the soil, the driving mechanism can drive the lifting base to move up and down, forcing the nails to be inserted into the loose soil holes, so that the soil forms a plurality of air holes distributed at intervals, so as to further enhance the air permeability of the soil.

At this time, changing the corresponding positioning hole 221 matched and plugged by the positioning column 11 can play a role in adjusting the height of the loosening mechanism 3.

[0038] Back to Figure 3 The end of the positioning column 11 away from the device assembly 1 can be detachably installed with a limiting component, which can abut against the side of the connecting arm plate 22 away from the device assembly 1 to prevent the connecting arm plate 22 from directly separating from the positioning column 11; the limiting component in this embodiment is a rotary cover 12, and the outer peripheral surface of the rotary cover 12 is evenly provided with a plurality of structural grooves 121, which can facilitate the operator to hold and rotate the rotary cover 12.
