Technical Field
[0001] This utility model belongs to the field of turf cultivation technology, specifically relating to a cool-season turf cultivation device. Background Technology
[0002] Cool-season grasses are those with strong cold resistance, remaining evergreen or dormant in some regions during winter, growing vigorously in spring and autumn, but not tolerant of summer heat. Examples include various types of creeping bentgrass, Kentucky bluegrass, and ryegrass. Turfgrass plants are classified into warm-season and cool-season grasses based on their growing climate. Cool-season grasses thrive in temperatures between 15℃ and 25℃. During cultivation and maintenance, mowing is necessary to keep the lawn neat and aesthetically pleasing, promote metabolism and tillering, increase density and evenness, and result in a vibrant green color and robust plants.
[0003] In existing cool-season lawn care devices, when the grass is growing vigorously, it is not easy to see the gravel hidden in the grass with the naked eye. When the blades at the bottom of the cart rotate, they may collide with these gravel, causing blade wear or machine malfunction, resulting in property damage and delaying the mowing work.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1-3 , Figures 5-7 As shown, a cool-season turf cultivation device includes a push rod 103 fixedly assembled to one end of a housing 1. A transmission chamber 102 is fixedly assembled inside the housing 1. A blade cover 119 is fixedly connected to one end of the transmission chamber 102. A crossbar 104 is fixedly connected to the middle of the push rod 103. A secondary rod 105 is rotatably connected to the outer wall of the crossbar 104. A connecting rod 117 is fixedly connected to one end of the secondary rod 105, located inside the housing 1. A protrusion 118 is fixedly connected to the middle of the connecting rod 117. A cover ring 120 is slidably assembled to the outer wall of the blade cover 119. The bottom of the cover ring 120 is fixed... A skirt plate 122 is connected to the cover ring 120. Conical blocks 121 are fixedly connected to both sides of the cover ring 120. Rollers 124 are rotatably connected to the bottom of the conical blocks 121. Grate columns 125 are fixedly connected in an array on both sides of the bottom of the skirt plate 122 and on one side of the rollers 124. Collection chambers 106 are symmetrically and movably assembled on both sides of the cover ring 120. Panels 123 are symmetrically and fixedly connected to both sides of the cover ring 120. The collection chambers 106 are movably fitted with the panels 123 through the grooves 101. A moving mechanism for controlling the movement of the cover ring 120 is assembled inside the outer shell 1 and above the cover ring 120.
[0026] According to the above structure, the push rod 103 pushes the cart to move. When the cart moves, the transmission chamber 102 drives the blades in the blade cover 119 to rotate and trim the lawn. The skirt plate 122 scoops up the gravel encountered on the ground and guides it into the collection chamber 106 through the conical block 121. The collection chamber 106 can be unfastened to the panel 123 through the groove 101, thereby removing the gravel. The cover ring 120 contacts the ground through the roller 124. When the terrain changes, the skirt plate 122 can extend and retract up and down through the moving mechanism, so that the roller 124 and the grate 125 always keep in contact with the ground. The grate 125 helps to block smaller gravel outside the blade cover 119.
[0027] See attached document Figures 2-3 , Figures 6-7 The moving mechanism includes connecting posts 116 fixedly assembled on the top of the conical block 121. A connecting plate 107 is fixedly connected to the top of both connecting posts 116. A second fixing plate 126 is symmetrically fixedly connected inside the outer casing 1. The second fixing plate 126 is elastically connected to the connecting plate 107 via a second spring post 127. A connecting ring 108 is fixedly connected to the middle of the connecting plate 107, located outside the cover ring 120. A wedge block 109 is fixedly connected to one end of the connecting plate 107 near the protrusion 118. The moving mechanism also includes a component movably fitted onto the wedge block 1. The wedge-shaped block 112 above 109 is movably disposed on one side of the protrusion 118. One end of the wedge-shaped block 112 is fixedly connected to the protrusion 114. One side of the protrusion 114 is fixedly connected to the limiting rod 111. The inner wall of the outer shell 1 is fixedly connected to the vertical plate 110. The limiting rod 111 and the vertical plate 110 are slidably connected through each other. The two sides of the wedge-shaped block 112 are symmetrically elastically assembled with spring pillars 113. The inner wall of the outer shell 1 is symmetrically fixedly connected with fixing plates 115. The fixing plates 115 and the spring pillars 113 are elastically connected.
[0028] According to the above structure, the cover ring 120 can extend and retract vertically through the connection between the connecting post 116 and the connecting plate 107, and the connection between the connecting plate 107, the second spring post 127, and the second fixing plate 126. When the terrain changes significantly, the protrusion 118 can be moved by rotating the auxiliary rod 105. The protrusion 118 pushes the second wedge block 112 to move. While the protrusion plate 114 moves with the second wedge block 112, the limiting rod 111 slides within the vertical plate 110 to limit the angle of the movement of the second wedge block 112. The first spring post 113 is used for the rebound and reset of the second wedge block 112. The movement of the second wedge block 112 increases the compression of the first wedge block 109. Under the tension of the second spring post 127, the connecting... The plate 107 and the cover ring 120 descend, or reduce the pressure on the wedge block 109. Under the contraction of the spring column 127, the connecting plate 107 and the cover ring 120 move upward, so that the skirt plate 122 conforms to the terrain changes and prevents it from getting stuck in the ground. This utility model, by sliding the cover ring 120 and the skirt plate 122 on the outside of the blade cover 119, can shovel the gravel hidden in the lawn to both sides in advance, preventing the lawn mower blade from colliding with the gravel and wearing it, and ensuring the mowing work can proceed. At the same time, the cover ring 120 can bounce up and down with the terrain during the movement of the device, or the cover ring 120 can be adjusted and controlled by the auxiliary rod 105, so that it always fits the ground, and together with the grate column 125, it can improve the effect of filtering gravel.
[0029] The working principle of this utility model is as follows: the push rod 103 pushes the cart to move. When the cart moves, the transmission chamber 102 drives the blades in the blade cover 119 to rotate and trim the lawn. The skirt plate 122 scoops up the gravel encountered on the ground and guides it into the collection chamber 106 through the conical block 121. The collection chamber 106 can be disengaged from the insert plate 123 through the groove 101, thereby removing the gravel. The cover ring 120 contacts the ground through the roller 124. When the terrain changes, the skirt plate 122 can extend and retract up and down through the moving mechanism, so that the roller 124 and the grate post 125 always keep in contact with the ground. The grate post 125 helps to block smaller gravel outside the blade cover 119. The cover ring 120 can be connected to the connecting plate 107 through the connecting post 116, the connecting plate 107, the spring post 127, and the fixing mechanism. The connection between the two plates 126 allows for vertical extension and retraction. When the terrain changes significantly, the protrusion 118 can be moved by rotating the auxiliary rod 105. The protrusion 118 pushes the wedge block 112 to move. As the protrusion plate 114 moves with the wedge block 112, the limiting rod 111 slides within the vertical plate 110 to limit the angle of the movement of the wedge block 112. The spring column 113 is used for the rebound and reset of the wedge block 112. The movement of the wedge block 112 increases the compression of the wedge block 109. Under the tension of the spring column 127, the connecting plate 107 and the cover ring 120 are lowered, or the compression of the wedge block 109 is reduced. Under the contraction of the spring column 127, the connecting plate 107 and the cover ring 120 are moved upward, thereby allowing the skirt plate 122 to adapt to the terrain changes and prevent it from getting stuck in the ground.
[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
