[0002] Gardening is the creation of a beautiful natural environment and recreational space within a certain area by using engineering technology and artistic means, through transforming the terrain (such as building mountains, stacking stones, and managing water), planting trees, flowers, and plants, constructing buildings, and arranging garden paths. Most gardening projects require planting lawns. Before sowing the lawn, the land must be finely prepared to clear away stones and debris, make the land level and smooth, then plow the land, and mix the topsoil and additives evenly.

[0003] Lawn tillers are mainly used for loosening the soil in green spaces such as lawns and gardens. They can effectively remove obstacles such as weeds and tree roots in the soil and improve the air permeability and water retention of the soil. Current tillers are generally composed of a handle, a power system, a transmission system and a loosening shovel. During operation, workers need to control the loosening depth and path by hand. When the soil is relatively moist, manual walking is more laborious. The loosening depth of a lawn tiller is generally shallow, usually only between 5 cm and 10 cm. This depth may not be enough to meet the deep needs of soil improvement for some lawns or before sowing grass seeds. Utility Model Content

[0017] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] Combined with Figure 1 , Figure 2 , Figure 3 A lawn loosening device for landscaping engineering comprises an agricultural machinery head 1 and a loosening assembly 2. The agricultural machinery head 1 is composed of a frame 3, track wheels 4, a driving machine 5, and a connecting frame 6. The connecting frame 6 is fixed behind the frame 3. The driving machine 5 is used as a driving machine 5 for driving the track wheels 4 forward. The frame 3 is provided with a seat and a steering wheel. The loosening assembly 2 is installed on the rear side of the connecting frame 6. The connecting frame 6 is provided with a slide 7. A plurality of guide rods 8 are provided in the slide 7. A hydraulic cylinder 9 is symmetrically provided on the slide 7. The loosening assembly 2 comprises a lifting plate 10 and a cross plate 11. The lifting plate 10 is located in the slide 7. The lifting plate 10 is slidably connected to the guide rod 8. The cross plate Connecting rods 12 are provided on both sides of 11, and the connecting rods 12 are fixed under the lifting plate 10. A plurality of rotating shafts 13 are rotatably provided on the horizontal plate 11. The upper end of the rotating shaft 13 is provided with a first belt pulley 14 and a second belt pulley 15, and the lower end of the rotating shaft 13 is provided with a rotary tiller 16. The rotary tiller 16 is conical, and the drill tip of the rotary tiller 16 is arranged higher than the bottom surface of the crawler wheel 4. The spiral blades of the two adjacent rotary tillers 16 are left spiral blades and right spiral blades respectively. When cultivating the land, the soil will be cut and rubbed by the left and right drill rods to be crushed and formed at one time, and the soft soil will automatically rise up due to the action of the spiral line, so that there is more air inside the soil;

[0020] When turning the soil of the lawn, the lifting plate 10 and the horizontal plate 11 are driven downward by the hydraulic cylinder 9, so that the rotary tiller 16 is partially inserted into the soil. The staff directly operates the movement of the frame 3, and multiple rotary tillers 16 are used to loosen the soil of the lawn. The loosening component 2 can be adjusted up and down in height, thereby adjusting the loosening depth of the rotary tiller 16.

[0021] A triangular support frame 17 is provided between the connecting rod 12 and the lifting plate 10. The connecting rod 12 is slidably connected to the connecting frame 6. The triangular support frame 17 and the plurality of guide rods 8 can improve the stability of the lifting plate 10 during the up and down movement.

[0022] A protective cover 18 is provided on the transverse plate 11, and a motor 19 is provided on the protective cover 18. The output shaft of the motor 19 is connected to the outermost rotating shaft 13, and the first pulley 14 and the second pulley 15 are connected through a transmission belt 20.

[0023] Among them, the rotating shaft 13 connected to the motor 19 has a certain angle with other rotating shafts 13. Under the drive of the motor 19, the rotating shaft 13 drives multiple rotating shafts 13 to rotate simultaneously through the transmission belts 20 connected in sequence up and down, thereby driving the rotary tiller 16 to operate synchronously.

[0024] The cross plate 11 is clamped in the slide groove 7, the hydraulic cylinder 9 is fixed on the cross plate 11 and located between the guide rods 8, and a reinforcement sleeve 21 is sleeved on the cross plate 11 and located on the outside of the guide rods 8. The reinforcement sleeve 21 can increase the stability of the connection between the lifting plate 10 and the guide rods 8 to avoid deformation of the guide rods 8 caused by excessive pressure on one side of the lifting plate 10.

[0025] During the specific implementation of the utility model, a worker sits on the frame to control the movement of the frame, starts the hydraulic cylinder to drive the lifting plate to move downward along the guide rod in the slide groove until the rotary tillage head is inserted into the soil, continues to adjust the feed depth of the rotary tillage head, starts the motor to drive the rotating shaft to rotate, and drives multiple rotating shafts to rotate in sequence through the first pulley, the second pulley and the transmission belt, so that the rotary tillage head rotates to loosen the lawn.

[0026] Compared with the prior art, the product of the utility model has a simpler structure as a whole, and each component is not a precision component, so it is easy to produce and manufacture, and the cost is also low.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
