Description

Technical Field

[0001] This utility model relates to the field of grass paving cutting technology, and in particular to a cutting device for grass pavers. Background Technology

[0002] Grass pavers are structural bricks characterized by gaps on their surface that allow for the planting of lawns or other plants, enhancing the aesthetic appeal of green spaces. Typically made of concrete or other materials, grass pavers possess a certain load-bearing capacity and durability. They are widely used in urban roads, plazas, landscaping, and rooftop gardens. Using grass pavers can increase urban green coverage, improve the environment, reduce the urban heat island effect, and also facilitate rainwater infiltration and soil conservation.

[0003] The production of grass pavers mostly involves injecting concrete slurry into molds, and then demolding them after the concrete has solidified. However, in current production methods, due to the gaps in the molds, burrs and excess material are often left on the edges of the raw grass pavers. If these burrs and excess material are not removed, it will affect the splicing and laying of the pavers. Therefore, after the grass pavers are removed from the molds, cutting equipment is needed to remove the burrs and excess material from the edges. Currently, this removal requires operators to manually place the grass pavers on a processing table and adjust the edges. Position the grass bricks (ensuring they are directly below the cutting equipment), then use clamps to limit their movement. Once the cutting equipment is started, it will cut the edges of the grass bricks. After cutting, the operator manually releases the clamps and removes the grass bricks from the processing table. This process is repeated to process the grass bricks in sequence. Although this removes burrs and excess material from the edges of the bricks, it requires the operator to constantly load and unload the bricks and adjust their positions, which increases the complexity, time, and effort required for cutting the grass bricks.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figure 1-5 One embodiment of this utility model provides: a cutting device for grass pavers, comprising: Conveyor belt 1 has a cutting device fixedly installed on its top for removing burrs and excess material from the edges of the bricks. A U-shaped plate is fixedly installed on the top of conveyor belt 1, and a hydraulic cylinder is fixedly installed on the top of the U-shaped plate. Side plates are fixedly installed on both sides of conveyor belt 1, and one end of the U-shaped plate is fixedly connected to the outer wall of each of the two side plates (e.g., ...). Figure 1 As shown in the figure, the rotational connection between the U-shaped plate and the conveyor belt 1, as well as the support for the U-shaped plate, can be achieved through the two side plates.

[0016] The power output end of the hydraulic cylinder is detachably equipped with a mounting block 3 that is the same shape as the grass paver. A threaded post is fixedly installed on the power output end of the hydraulic cylinder, and a threaded tube 6 that matches the threaded post is fixedly installed on the other end of the mounting block 3. One end of the mounting block 3 can be connected to the power output end of the hydraulic cylinder through the mutual cooperation of the threaded tube 6 and the threaded post. When the mounting block 3 needs to be replaced, simply rotate the threaded tube 6 to make the threaded tube 6 and the threaded post rotate relative to each other until the threaded post is completely removed from the inner cavity of the threaded tube 6. This will separate the mounting block 3 from the power output end of the hydraulic cylinder, so that the mounting block 3 can be replaced.

[0017] The shape of the mounting block 3 is the same as that of the grass paver, and the size of the mounting block 3 is slightly larger than that of the grass paver that needs to be cut.

[0018] Multiple positioning blocks 2 are detachably installed on the outer wall of the conveyor belt 1 along its rotation direction. Multiple elastic plates 7 are fixedly installed on the outer wall of the positioning blocks 2 to press against the inner wall of the grass pavers. The elastic plates 7 are designed with an L-shaped structure. When the positioning blocks 2 are installed outside the conveyor belt 1, the end of the elastic plate 7 away from the positioning blocks 2 points towards the conveyor belt 1. When the grass pavers are placed on top of the conveyor belt 1, they are fitted onto the outside of the positioning blocks 2. At this time, the outer walls of the multiple elastic plates 7 are in contact with the inner wall of the grass pavers. Under the pressure of the inner wall of the grass pavers, the multiple elastic plates 7 are deformed by force, thereby increasing the friction between the elastic plates 7 and the inner wall of the positioning blocks 2. This prevents the positioning blocks 2 from shaking when moving with the conveyor belt 1 and when removing burrs and residue from the edges of the grass pavers, thus improving the stability when removing burrs and residue from the edges of the grass pavers.

[0019] The included angle of the elastic plate 7 is greater than 90°, which allows the grass brick to be smoothly fitted onto the outside of the positioning block 2. At the same time, when the bottom of the grass brick is in contact with the top of the conveyor belt 1, the included angle of the elastic plate 7 is close to 90°, thereby increasing the contact area between the outer wall of the elastic plate 7 and the inner wall of the grass brick, and further improving the stability of the grass brick.

[0020] The elastic plate 7 is made of stainless steel, which can increase the number of bends at the bends of the elastic plate 7 and the strength of the elastic plate 7, thereby improving the service life of the elastic plate 7.

[0021] Multiple positioning tubes 9 are fixedly installed on the outer wall of the conveyor belt 1 along the rotation direction of the conveyor belt 1. One end of each positioning block 2 has a positioning hole adapted to the positioning tube 9. A limit bolt 8 is detachably installed in the inner cavity of the positioning hole. The inner wall of the positioning tube 9 has a threaded groove adapted to the limit bolt 8. Since the grass pavers have different sizes, the inner hole size of different sizes of grass pavers is different. When limiting different sizes of grass pavers, it is necessary to replace the positioning block 2 and the elastic plate 7 with different sizes so that the grass pavers can smoothly fit onto the outer wall of the positioning block 2 through the inner hole, and the outer wall of the elastic plate 7 and the inner wall of the grass pavers are tightly fitted. When replacing the positioning block 2, continuously rotate the large end of the limit bolt 8 until the limit is reached. The positioning bolt 8 is completely separated from the inside of the positioning tube 9. Then, the positioning block 2 is pulled out from the outside of the positioning tube 9. The positioning block 2 that matches the grass paver is then fitted onto the outside of the positioning tube 9 through the positioning hole until the bottom of the positioning block 2 is in contact with the top of the conveyor belt 1. Then, the small end of the limiting bolt 8 is inserted into the inside of the positioning tube 9 through the positioning hole. Then, the large end of the limiting bolt 8 is continuously rotated until the large end of the limiting bolt 8 and the top of the positioning block 2 are tightly fitted. The positioning block 2 can be limited by the limiting bolt 8 to prevent it from detaching from the conveyor belt 1. Positioning blocks 2 of different sizes can be replaced so that grass pavers of different sizes can be limited by the cooperation of the positioning block 2 and the elastic plate 7.

[0022] When the grass paver moves to the underside of the conveyor belt 1 as it rotates, the weight of the grass paver is greater than the friction between the elastic plate 7 and the grass paver. As a result, the grass paver falls off the outside of the conveyor belt 1 under the action of gravity, which realizes automatic feeding of the grass paver. No manual intervention is required for feeding the grass paver, which reduces the tediousness of cutting grass paver blanks and the time and effort required.

[0023] Multiple cutting blades 4 are fixedly installed at one edge of the mounting block 3, with adjacent ends of two adjacent cutting blades 4 fixedly connected. The shape of the cutting blades 4 arranged together is the same as the shape of the mounting block 3. When one of the grass pavers moves directly below the mounting block 3 (the top center axis of the grass paver coincides with the center axis of one end of the mounting block 3), the conveyor belt 1 stops rotating. Then, the hydraulic cylinder is activated, causing the power output end of the hydraulic cylinder to move downward until the tips of the multiple cutting blades 4 are in contact with the edge of the grass paver. As the power output end of the hydraulic cylinder continues to move downward, the tips of the multiple cutting blades 4 can move along the edge of the grass paver, thus removing burrs and excess material from the edge of the grass paver. Then, the power output end of the hydraulic cylinder is moved upward until the cutting blades 4 move directly above the grass paver. Then, the conveyor belt 1 is activated until the uncut grass paver moves directly below the mounting block 3 again, at which point the hydraulic cylinder is activated to cut the edge of the grass paver. Through the cooperation of the conveyor belt 1 and the hydraulic cylinder, burrs and excess material on the edges of multiple grass pavers can be continuously cut.

[0024] An industrial camera (model XCG-CP510, available for direct purchase on the market, using CCD industrial camera positioning technology, a current technology) is fixedly installed on the inner wall of the U-shaped plate. The lens of the industrial camera is always aimed directly below the cutting blade 4. At the same time, QR code patches are fixedly installed on the top of multiple positioning blocks 2. After the camera end of the industrial camera recognizes the QR code patch on the top of one of the positioning blocks 2, it transmits the position information of the positioning block 2 to the background controller. When the positioning block 2 moves to the point where the coordinates of its own central axis are the same as the coordinates of the end central axis of the mounting block 3, the conveyor belt 1 stops rotating. This ensures that the central axis of the grass brick being cut can coincide with the central axis of the mounting block 3, so that the cutting blade 4 can accurately cut the edge of the grass brick.

[0025] The cavity formed by the connection of multiple cutting blades 4 has an area slightly larger than that of the grass paver, so as to avoid the cutting blades 4 from contacting the top of the grass paver with the tip when the hydraulic cylinder power output end moves down, thus affecting the cutting of the grass paver edge.

[0026] The installation blocks 3 of different sizes can be replaced by the cooperation of the threaded tube 6 and the threaded column, so as to remove burrs and excess material from the edges of grass pavers of different sizes.

[0027] Based on the applicant's understanding of the prior art, when the cutting blade 4 cuts the edge of the grass brick located at the top of the conveyor belt 1, the cutting blade 4 continuously applies pressure to the top of the grass brick being cut, causing the top of the conveyor belt 1 to continuously sag. The continuous sag of the conveyor belt 1 will cause the grass brick being cut to shift severely. The severe shift of the grass brick will cause the cutting blade 4 to misalign with the grass brick and cut the top of the grass brick, making the grass brick being cut more prone to breakage or damage, thus reducing the pass rate of grass brick cutting.

[0028] To solve the above-mentioned technical problems, a support plate for supporting the inner wall of the conveyor belt 1 is fixedly installed inside the conveyor belt 1. The two ends of the support plate are fixedly connected to the adjacent side of the two side plates, and the distance between the top of the support plate and the top of the inner cavity of the conveyor belt 1 is no more than 1 mm. When the cutting blade 4 cuts the grass brick and causes the top of the conveyor belt 1 to be concave, the bottom of the concave surface of the conveyor belt 1 undergoes slight deformation and fits against the top of the support plate, thus supporting the top of the conveyor belt 1 and preventing the top of the conveyor belt 1 from being severely concave. The angle of deviation when cutting the grass brick is controlled within the allowable range, avoiding the cutting end of the cutting blade 4 from contacting the top of the grass brick being cut, which would cause the grass brick to break or break, thus improving the pass rate of grass brick cutting.

[0029] Since the distance between the top of the support plate and the top of the inner cavity of the conveyor belt 1 is no more than 1 mm, the inner wall of the conveyor belt 1 is kept in contact with the top of the support plate and friction occurs when the conveyor belt 1 rotates, which protects the conveyor belt 1. However, this also reduces the smoothness and stability of the conveyor belt 1 when it rotates.

[0030] A feeding plate 5 for feeding grass pavers is fixedly installed at the bottom of the conveyor belt 1. The feeding plate 5 is inclined away from the conveyor belt 1. After the grass pavers fall off the bottom of the conveyor belt 1, they will fall onto the top of the feeding plate 5 and slide along the top of the feeding plate 5 under the action of gravity. Then, the operator can collect the grass pavers that have slid to the bottom of the feeding plate 5. This cushions the sliding of the grass pavers and prevents them from hitting the ground and being damaged, thus protecting the grass pavers.

[0031] Furthermore, after the excess material and burrs at the edge of the grass brick are removed, they will accumulate on the top of the conveyor belt 1. When the accumulated burrs and excess material move to the bottom of the conveyor belt 1 as the conveyor belt 1 rotates, the burrs and excess material will fall off from the outside of the conveyor belt 1 under the action of gravity, thus achieving self-cleaning of the outside of the conveyor belt 1, which will facilitate the subsequent cutting operation at the edge of the grass brick.

[0032] The positioning block 2, elastic plate 7, positioning tube 9 and limiting bolt 8 constitute the positioning component. The positioning component can not only continuously transport the brick, but also allow the cut brick to be automatically unloaded from the top of the conveyor belt 1 without manual intervention in the unloading of grass bricks, thus reducing the tediousness of cutting grass bricks and the time and effort required.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
